TL;DR: It is identified that the normal NLR values in an adult, non-geriatric, population in good health are between 0.78 and 3.53.
Abstract: Neutrophil-to-lymphocyte ratio (NLR) has proven its prognostic value in cardiovascular diseases, infections, inflammatory diseases and in several types of cancers. However, no cut-off has been proposed on the basis of reference values coming from healthy population. Routine blood samples were obtained (n = 413) from workers (age: median 38, range: 21–66 years) involved in a health care prevention program, to determine means, standard deviations (SDs), 95% confidence intervals (95% CI), percentiles P2.5 and P97.5. A second independent sample of healthy volunteers is compared (n = 29). The mean NLR is 1.65 [±1.96 SD: 0.78–3.53] (95% CI [0.75–0.81] and [3.40–3.66]). In the second cohort (healthy control), the NLR values are in the same range, whichever the used analyzer. No NLR assessed in the validation series is out of the proposed limits. We have identified that the normal NLR values in an adult, non-geriatric, population in good health are between 0.78 and 3.53. These data will help to define the normal values of the NLR.

TL;DR: It is concluded that different agro-climatic conditions have effects on the phytochemicals, total phenolic content (TPC) and antioxidant potential of the A. vera plant and it can be a potential source of novel natural antioxidant compounds.
Abstract: The aim of the present study was to analyse the effect of climate change on phytochemicals, total phenolic content (TPC) and antioxidant potential of methanolic extracts of Aloe vera collected from different climatic zones of the India. Crude methanolic extracts of A. vera from the different states of India were screened for presence of various phytochemicals, total phenolic content and in vitro antioxidant activity. Total phenolic content was tested by Folin–Ciocalteau reagent based assay whilst DPPH free radical scavenging assay, metal chelating assay, hydrogen peroxide scavenging assay, reducing power assay and β carotene-linoleic assay were used to assess the antioxidant potential of A. vera methanolic leaf extracts. Alkaloids, phenols, flavonoids, saponins, and terpenes were the main phytochemicals presents in all accessions. A significant positive correlation was found between TPC and antioxidant activity of different accessions. Extracts of highland and semi-arid zones possessed maximum antioxidant potential. Accessions from tropical zones showed the least antioxidant activity in all assays. It could be concluded that different agro-climatic conditions have effects on the phytochemicals, total phenolic content (TPC) and antioxidant potential of the A. vera plant. The results reveal that A. vera can be a potential source of novel natural antioxidant compounds.

TL;DR: Evaluated social media use among healthcare workers in South Texas found that a large proportion of healthcare workers were unaware of their workplace policy, which could potentially cause a privacy breach of confidential medical information.
Abstract: The objective of this study was to evaluate the use of social media among healthcare workers in an attempt to identify how it affects the quality of patient care. An anonymous survey of 35 questions was conducted in South Texas, on 366 healthcare workers. Of the 97% of people who reported owning electronic devices, 87.9% indicated that they used social media. These healthcare workers indicated that they spent approximately 1 h on social media every day. The healthcare workers below the age of 40 were more involved in social media compared to those above 40 (p < 0.05). The use of social media among physicians and nurses was noted to be identical (88% for each group), and both groups encouraged their patients to research their clinical conditions on social media (p < 0.05). A higher number of physicians reported awareness of a social media policy in their hospital compared to nurses (p < 0.05). However, a large proportion of healthcare workers (40%) were unaware of their workplace policy, which could potentially cause a privacy breach of confidential medical information. Further studies are required to evaluate specific effects of these findings on the quality of patient care.

TL;DR: It is found that G. mellonella larvae can be used in infectivity trials and toxicity testing, and that these assays represent an inexpensive and readily executable alternative to testing in rodents.
Abstract: Infectivity trials and toxicity testing in rodents are important prerequisites to the use of compounds in man. However, trials in rats and mice are expensive and there are ethical considerations. Galleria mellonella (greater wax moth) larvae are a potential alternative. We have assessed the use of these insects in infectivity trials and toxicity testing. Using four bacterial species (two Gram-negative and two Gram-positive) we have assessed the efficacy of four antibiotics against infections in Galleria and compared the antibiotic susceptibility with that in humans. In general, we find a good correlation. Similarly, we have assessed 11 compounds (initially tested blind) for their toxicity in Galleria and compared this with toxicity trials in mice and rats. Again we found a good correlation between toxicity in Galleria and that in rodents. We have found, in our hands, that G. mellonella larvae can be used in infectivity trials and toxicity testing, and that these assays represent an inexpensive and readily executable alternative to testing in rodents.

TL;DR: This study provided a systematic overview of productivity and visibility of research work in aromatherapy and the findings could be used for organizing and prioritizing future research efforts in arom Heatherapy research.
Abstract: Quantitative data are lacking on the profile of published research in aromatherapy. The objective of the study was to investigate the profile of original and review articles under the topic aromatherapy using bibliometric analysis. Articles on aromatherapy, published between 1995 and 2014, were retrieved from the Science Citation Index-Expanded database from the Web of Science. The records extracted were analyzed for citation characteristics, including the distribution of publication years, languages, countries or regions, journals, articles, and authors using HistCite 12.03.17. VOSviewer v.1.61 was used to construct bibliometric diagrams. A total of 549 original and review articles, published in 287 different peer-reviewed journals by 1888 authors, were identified. There was a steady increase in the number of published articles from 1995 to 2014. The majority of the articles was written in English (95.8%) and the United States was the leading country in the total number of published articles (n = 107, 19.5%) Journal of Alternative and Complementary Medicine published the greatest number of articles on the topic (n = 31, 5.6%). The article that received the greatest number of citations was published in Complementary Therapies in Medicine. Visualization analysis based on co-occurrences of words in the title and abstract revealed three clusters of research topics, including essential oil, intervention, and complementary medicine. This study provided a systematic overview of productivity and visibility of research work in aromatherapy and the findings could be used for organizing and prioritizing future research efforts in aromatherapy research.

TL;DR: The authors' results were consistent with past transcriptomics studies that have found immune and transport processes play a role in feed efficiency and are impacted by complex processes in the liver, which include cellular transport, metabolism regulation, and immune function.
Abstract: To better understand which genes play a role in cattle feed intake and gain, we evaluated differential expression of genes related to gain and intake in the liver of crossbred beef steers. Based on past transcriptomics studies on cattle liver, we hypothesized that genes related to metabolism regulation and the inflammatory response would be differentially expressed. This study used 16 animals with diverse gain and intake phenotypes to compare transcript abundance after a 78 day ad libitum feed study. A total of 729 genes were differentially expressed. These genes were analyzed for over-representation among biological and cellular functions, and pathways. Cell transport processes and metabolic processes, as well as functions related to transport, were identified. Pathways related to immune function, such as the proteasome ubiquitination pathway and the chemokine signaling pathway, were also identified. Our results were consistent with past transcriptomics studies that have found immune and transport processes play a role in feed efficiency. Gain and intake are impacted by complex processes in the liver, which include cellular transport, metabolism regulation, and immune function.

TL;DR: The results show that both GE students and their younger UG counterparts on a traditional medical course have similar profiles of stress symptoms, but GEs do, however, cope with stress differently and are more likely to use active problem-focused coping strategies and to cope by using substances.
Abstract: Stress levels and psychological morbidity are high among undergraduate medical students (UGs), but there is a lack of research into the psychological health of UK graduate-entry medical students (GEs). GEs are likely to experience different (perhaps more severe) stressors and to cope with stress differently. We compared stress levels, psychological morbidity and coping styles in GE versus UG medical students studying at the same UK medical school in the same academic year. A cross-sectional self-rated questionnaire study of all first- and second-year GE and UG medical students was conducted. Perceived stress, psychological morbidity, recent adverse life events, stress-related personality traits and coping styles were assessed using standard questionnaires. 75% GEs and 46% UGs responded to the questionnaire. Both groups reported equally high levels, and similar profiles of, perceived stress and psychological morbidity. Levels of recent adverse life events and stress-related personality traits were similar in both groups. Compared to UGs, GEs were more likely to use active coping (p = 0.02) and positive reframing (p = 0.03), but were also more likely to use substances (alcohol and other drugs; p < 0.001) to help them cope. Unlike UGs, second-year GEs showed less perceived stress (p = 0.007) and psychological morbidity (p = 0.006) than first-year GEs although levels of both were still high. Our results show that both GE students and their younger UG counterparts on a traditional medical course have similar profiles of stress symptoms. They do, however, cope with stress differently. GEs are more likely to use active problem-focused coping strategies, and they are also more likely to cope by using substances (alcohol or other drugs). GE students need interventions to prevent maladaptive coping styles and encourage adaptive coping that are tailored to their needs. Such interventions should be targeted at first-year students. It is vital that these students develop positive coping skills to benefit them during training and in a future career that is inherently stressful.

TL;DR: There is a need for development of strong policies on antibiotic stewardship, antimicrobial surveillance and infection control to help guide empirical antibiotic therapy and prevent the spread of MDR bacteria and antibiotic drug resistance.
Abstract: The intensive care unit (ICU) admits critically ill patients requiring advanced airway, respiratory, cardiac and renal support. Despite the highly-specialized interventions, the mortality and morbidity is still high due to a number of reasons including nosocomial infections, which are the most likely complications in hospitalized patients with the rates being highest among ICU patients. In this cross-sectional study of 111 adult patients admitted to 2 of the ICUs in Uganda, we set out to describe the commonest bacterial infections, their antimicrobial susceptibility patterns and factors associated with development of a nosocomial infection. Klebsiella pneumoniae (30%), Acinetobacter species (22%) and Staphylococcus aureus (14%) were the most frequently isolated bacteria. The prevalence of multidrug resistant bacterial species was 58%; 50% Escherichia coli and 33.3% Klebsiella pneumoniae were extended spectrum beta lactamase or AmpC beta lactamase producers and 9.1% Acinetobacter species were extensive drug resistant. Imipenem was the antibiotic with the highest susceptibility rates across most bacterial species. Institution of ventilator support (P 0.003) and severe traumatic brain injury (P 0.035) were highly associated with the development of nosocomial infections. Due to the high prevalence of multi drug resistant (MDR) and extensive drug resistant bacterial species, there is a need for development of strong policies on antibiotic stewardship, antimicrobial surveillance and infection control to help guide empirical antibiotic therapy and prevent the spread of MDR bacteria and antibiotic drug resistance.

TL;DR: Cognitive and emotional representation of diabetes and diabetes knowledge are key determinants of patients’ diabetes self-care practices and it is therefore important that appropriate psychosocial interventions are developed to help Patients’ adherence to recommended self-Care practices.
Abstract: Self-care practices among persons living with type-2 diabetes are very crucial in diabetes manages as poor self-care results in complications. However, little research exists within the Ghanaian context. This study examined whether type-2 diabetes patients’ illness perception and diabetes knowledge significantly predict diabetes self-care practices. A cross-sectional survey design was employed and a total of 160 participants (45 males and 115 females) were sampled from a general hospital in Accra. A self-administered questionnaire measuring illness perception, diabetes knowledge and diabetes self-care practices as well as demographic checklist were used collect data. Results showed that illness perception and diabetes knowledge significantly predicted overall diabetes self-care practices. Analysis of domain specific self-care practices showed that patients’ diet was significantly predicted by illness perception and diabetes knowledge. Exercise was significantly predicted by only illness perception while blood sugar testing and diabetes foot-care were significantly predicted by diabetes knowledge. Cognitive and emotional representation of diabetes and diabetes knowledge are key determinants of patients’ diabetes self-care practices. It is therefore important that appropriate psychosocial interventions are developed to help patients’ adherence to recommended self-care practices.

TL;DR: Dega Damot district is loaded in its medicinal plant diversity and indigenous knowledge Though plants are highly affected by drought, overgrazing and firewood collection, awareness activities must be created among the district's population by concerned governmental and nongovernmental organizations about the value of medicinal plants and conservation of these plants.
Abstract: One of the services that plants provide for human beings is their wider medicinal application. Although it is not fully assessed, the practice and wider use of traditional medicine is frequent in Ethiopia. Studies conducted previously are confined to the perceptions of modern and traditional health practitioners about traditional medicine. A total of 45 informants were selected purposefully from the study area. For collecting the data, semi-structured interviewees, observation and field walks were employed from August 10 to September 30/2014. To summarize the information, descriptive statistical methods were applied. Sixty species of medicinal plants distributed in 42 families were collected and identified applied locally for the treatment of 55 human disorders. The most commonly treated ones were evil eye, malaria, wound, peptic ulcer disease and rabies. According to this study, leaves were the commonly used plant parts (36.5%) and 39% of the preparations were decoctions. Oral route, 43 (44%) was the commonly used route of application whereas most (54.8%) remedies were administered only once. Fourteen percent of preparations caused vomiting in addition most (40.4%) of the formulations was contraindicated for pregnant patients. Only seventeen percent of the formulations possessed drug food interactions. Most preparations were stored within clothes, 31 (29.8%). There exists a high (ICF = 0.8) evenness of plant use among healers for treating respiratory problems. Alliumsativum (FI = 0.75) for evil eye, Phytolacca dodecandra (FI = 0.8) for rabies and Croton macrostachyus (FI = 0.78) for treating malaria were medicinal plants with highest fidelity levels showing consistency of knowledge on species best treating power. This study also documented that drought, overgrazing and firewood collection are major threats. Dega Damot district is loaded in its medicinal plant diversity and indigenous knowledge though plants are highly affected by drought, overgrazing and firewood collection. Therefore awareness activities must be created among the district’s population by concerned governmental and nongovernmental organizations about the value of medicinal plants and conservation of these plants. The healing potential and associated adverse issues of the claimed medicinal plants should be assessed before proposing for a broader utilization.

TL;DR: These results provide a partial replication of previous work showing that introducing larger glasses (without manipulating portion size) increases purchasing, and elucidate when the effect can be expected and when not.
Abstract: Wine glass size may influence perceived volume and subsequently purchasing and consumption. Using a larger glass to serve the same portions of wine was found to increase wine sales by 9.4% (95% CI 1.9, 17.5) in a recent study conducted in one bar. The current study aimed to replicate this previous work in two other bars using a wider range of glass sizes. To match the previous study, a repeated multiple treatment reversal design, during which wine was served in glasses of the same design but different sizes, was used. The study was conducted in two bars in Cambridge, England, using glass sizes of 300, 370, 510 ml (Bar 1) and 300 and 510 ml (Bar 2). Customers purchased their choice of a 750 ml bottle, or standard UK measures of 125, 175 or 250 ml of wine, each of which was served with the same glass. Bar 1 Daily wine volume (ml) purchased was 10.5% (95% CI 1.0, 20.9) higher when sold in 510 ml compared to 370 ml glasses; but sales were not significantly different with 300 ml vs. 370 ml glasses (6.5%, 95% CI −5.2, 19.6). Bar 2 Findings were inconclusive as to whether daily wine purchased differed when using 510 ml versus 300 ml glasses (−1.1%, 95% CI −12.6, 11.9). These results provide a partial replication of previous work showing that introducing larger glasses (without manipulating portion size) increases purchasing. Understanding the mechanisms by which wine glass size influences consumption may elucidate when the effect can be expected and when not. Trial registration This study is a replication study, based on the procedure set out in the trial registration for the study that it attempts to replicate (ISRCTN registry: ISRCTN12018175)
TL;DR: The clinical outcome of neonatal sepsis in Felege Hiwot referral hospital was not satisfactory and the significant risk factors for poor outcome were respiratory distress syndrome and meconium aspiration syndrome.
Abstract: Sepsis remains a major cause of morbidity and mortality among neonates. The risk factors and clinical outcomes of sepsis are poorly understood. Most cases of sepsis occurred mostly within the first week of newborns life related to perinatal risk factors. Late onset sepsis is related to hospital acquired infections which is seen after seven days of age. The purpose of this study was to assess clinical outcome and risk factors of neonatal sepsis in Felege Hiwot referral hospital Bahir Dar, North West Ethiopia. Among the total 225 neonatal charts reviewed; 164 (72.9%) were age less than or equal to 7 days, and 144 (64%) were males. About 29 (12.9%) neonates were with irregular respiratory signs and 40 (17.8%) had meconium aspiration syndrome. Regarding the clinical outcome of neonatal sepsis: 189 (84%) were improved after treatment, 9 (4%) were died and 13 (5.8%) referred to other organizations for further treatment. Respiratory distress syndrome [AOR = 0.258 (0.072–0.930)] and meconium aspiration syndrome [AOR = 0.1989 (0.059–0.664)] were the determinant factors for poor outcome of neonatal sepsis. The clinical outcome of neonatal sepsis in Felege Hiwot referral hospital was not satisfactory. The significant risk factors for poor outcome of neonatal sepsis were respiratory distress syndrome and meconium aspiration syndrome. Recommendations to improve neonatal outcome are: performing essential newborn care for all newborns and arranging appropriate follow up until the end of neonatal period, increasing antenatal care and early detection and management of neonatal infections or problems.
TL;DR: There is a myriad of eHealth projects being implemented in Kenya, mainly in the mHealth strategic area and focusing mostly on primary care and HIV/AIDs, although few projects are implemented in marginalised areas and least urbanized counties with more health care needs.
Abstract: The growth of Information and Communication Technology in Kenya has facilitated implementation of a large number of eHealth projects in a bid to cost-effectively address health and health system challenges. This systematic review aims to provide a situational analysis of eHealth initiatives being implemented in Kenya, including an assessment of the areas of focus and geographic distribution of the health projects. The search strategy involved peer and non-peer reviewed sources of relevant information relating to projects under implementation in Kenya. The projects were examined based on strategic area of implementation, health purpose and focus, geographic location, evaluation status and thematic area. A total of 114 citations comprising 69 eHealth projects fulfilled the inclusion criteria. The eHealth projects included 47 mHealth projects, 9 health information system projects, 8 eLearning projects and 5 telemedicine projects. In terms of projects geographical distribution, 24 were executed in Nairobi whilst 15 were designed to have a national coverage but only 3 were scaled up. In terms of health focus, 19 projects were mainly on primary care, 17 on HIV/AIDS and 11 on maternal and child health (MNCH). Only 8 projects were rigorously evaluated under randomized control trials. This review discovered that there is a myriad of eHealth projects being implemented in Kenya, mainly in the mHealth strategic area and focusing mostly on primary care and HIV/AIDs. Based on our analysis, most of the projects were rarely evaluated. In addition, few projects are implemented in marginalised areas and least urbanized counties with more health care needs, notwithstanding the fact that adoption of information and communication technology should aim to improve health equity (i.e. improve access to health care particularly in remote parts of the country in order to reduce geographical inequities) and contribute to overall health systems strengthening.
TL;DR: Implementing a vertical peer-mentoring program can be an effective adjunct to faculty mentoring and student perception of the program improved each year, including feeling more prepared, supported and satisfied with their overall experience in medical school.
Abstract: Background Effective mentoring is an important component of medical student professional development. We provide a description of the mentoring program at our institution. Methods Our institution UTHSCSA implemented a student-advising program (Veritas) with clinical faculty mentors and senior students (MiMs). The MiMs provided vertical peer mentoring to more junior students as an adjunct to faculty advising. The MiMs lead small group discussions that foster camaraderie, share academic and career information and promote professional identity. An optional MiM elective more intensively develops mentorship and leadership skills through a formal curriculum. The authors used annual survey data of all students as well as student mentors to evaluate program effectiveness. Results Overall, student perception of the program improved each year across multiple domains, including feeling more prepared, supported and satisfied with their overall experience in medical school. Student mentors also found the process rewarding and helpful to their future careers as physicians. Conclusions The authors suggest implementing a vertical peer-mentoring program can be an effective adjunct to faculty mentoring.
TL;DR: Malaria infection, frequency at which one consumed fish/snails and gestational age at first ANC visit were the main factors found to be associated with anaemia among the pregnant women.
Abstract: Anaemia in pregnancy is an important health issue resulting in high maternal morbidity and mortality. The purpose of the current study was to identify factors associated with anaemia among pregnant women receiving antenatal care at the Sunyani Municipal Hospital in Ghana. A cross-sectional study involving pregnant women seeking antenatal care at the Sunyani Municipal Hospital was conducted between May and June, 2015. It involved the collection of data on socio demographic and obstetric variables, medical interventions and malaria infection, consumption of iron containing foods and supplements using a case record form and a structured questionnaire. Also, data on haemoglobin concentrations at first and current antenatal visit were collected. Bivariate and multivariate statistical analysis were done to determine factors associated with anaemia. Out of the 316 participants, 129 (40.8%) were found to be anaemic (Hb <11.0 g/dl) at the time of their first ANC visit (mean Hb: 11.21 g/dl, range 6.8–15.1 g/dl). Seventy-nine (61.2%) of them had mild anemia (Hb 9.0–10.9 g/dl), 48 (37.2%) had moderate anemia (Hb 7.0–8.9 g/dl) whilst 2 (1.6%) had severe anemia (Hb <7.0 g/dl). During their most recent ANC visit, the prevalence of anaemia was found to be similar to that of the first visit with 131 (41.5%) of them being anaemic [mean Hb: 11.24 g/dl, range 8.10–14.5 g/dl]. The haemoglobin levels however improved significantly during the most recent visit compared to the first with none of the women being severely anaemic (Hb <7.0 g/dl). The prevalence of moderate anaemia reduced from 37.2% (CI 28.9–46.2) during the first visit to 19.1% (12.7–26.9) during the most recent visit, a reduction of 48.7%. Malaria infection, frequency at which one consumed fish/snails and gestational age at first ANC visit were the main factors found to be associated with anaemia among the pregnant women. Malaria infection, fish/snails intake and gestational age at first ANC visit were significantly associated with anaemia. Addressing these factors can reduce the incidence of anaemia in pregnancy.
TL;DR: The results suggest that the plasma levels of CAT, TAC and reduced glutathione could give information on the risk of developing complications of diabetes, considering that the modification of these biomarkers levels were associated with oxidative stress.
Abstract: Studies demonstrate that free radicals are involved in the pathogenesis of diabetic complications. The aim of this study was to determine the implication of total antioxidant capacity (TAC) and some enzymatic and non-enzymatic antioxidants as suitable biomarkers of diabetic complications risk factors. A total of 90 patients (70 patients with or without diabetic complications +20 normal healthy) were examined by evaluating the level of lipid peroxidation, nitrogen monoxide (NO), fasting blood glucose, glycated haemoglobin (HbA1c), enzymatic and non-enzymatic antioxidants using standard spectrophotometric methods. The fasting blood glucose and HbA1c levels were respectively 2.05 and 2.32 times higher in the group of patients with diabetes and complications (DPWC) compared to those of healthy persons. A statistically higher level of malondialdehyde (MDA), NO and TAC was observed in a group of patients with diabetes and complications compared to those without complications (DPNC). A significant positive correlation was found between catalase (CAT) and fasting blood glucose while a significant and negative correlation was noted between reduced glutathione (GSH) and fasting blood glucose. Also was noted a significant relationship between HbA1c and other markers of oxidative stress. The results suggest that the plasma levels of CAT, TAC and reduced glutathione could give information on the risk of developing complications of diabetes, considering that the modification of these biomarkers levels were associated with oxidative stress.
TL;DR: By inhibiting ROS generation, increasing ALDH activity and decreasing the presence of acrolein, NAC has the potential to prevent CY-induced cardiotoxicity.
Abstract: The dose-limiting toxic effect of cyclophosphamide (CY) is cardiotoxicity. The pathogenesis of myocardial damage is poorly understood, and there is no established means of prevention. In previous studies, we suggested that for CY-induced cardiotoxicity, whereas acrolein is the key toxic metabolite, carboxyethylphosphoramide mustard (CEPM) is protective. We sought to verify that acrolein is the main cause of cardiotoxicity and to investigate whether aldehyde dehydrogenase (ALDH), which is associated with greater CEPM production, is involved in the protective effect for cardiotoxicity. We also evaluated the protective effect of N-acetylcysteine (NAC), an amino acid with antioxidant activity and a known acrolein scavenger. H9c2 cells were exposed to CY metabolites HCY (4-hydroxy-cyclophosphamide), acrolein or CEPM. The degree of cytotoxicity was evaluated by MTT assay, lactate dehydrogenase (LDH) release, and the production of reactive oxygen species (ROS). We also investigated how the myocardial cellular protective effects of CY metabolites were modified by NAC. To quantify acrolein levels, we measured the culture supernatants using high performance liquid chromatography. We measured ALDH activity after exposure to HCY or acrolein and the same with pre-treatment with NAC. Exposure of H9c2 cells to CEPM did not cause cytotoxicity. Increased ROS levels and myocardial cytotoxicity, however, were induced by HCY and acrolein. In cell cultures, HCY was metabolized to acrolein. Less ALDH activity was observed after exposure to HCY or acrolein. Treatment with NAC reduced acrolein concentrations. Increased ROS generation and decreased ALDH activity confirmed that CY metabolites HCY and acrolein are strongly implicated in cardiotoxicity. By inhibiting ROS generation, increasing ALDH activity and decreasing the presence of acrolein, NAC has the potential to prevent CY-induced cardiotoxicity.
TL;DR: Adherence of patients to regular follow up and diabetes treatment for 5–10 years and level of education and duration of diabetes treatment are found to be independent predictors of glycemic control among type 2 diabetes patients.
Abstract: The aim of this study was to assess the rate of glycemic control and factors affecting glycemic control in type 2 diabetic patients. A total of 174 type 2 diabetic patients were interviewed and were studied. Mean age of the patients was 48.98 ± 14.96 years (range 18–80 years). More than half (51.7%) of the patients were males. About a third of patients, 53 (30.5%), were on antidiabetic medications for less than 5 years. The most common prescribed antidiabetic medications were insulin, 48 (27.6%), and metformin 15 (8.6%). One hundred seven (61.5%) patients were on combination therapy (two drug treatment) and the remaining patients were on monotherapy. The majority, 103 (59.2%), of patients had uncontrolled blood glucose. A larger proportion of female patients, 54 (52.4%), had uncontrolled blood glucose than males. Level of education (p < 0.001) and duration of diabetes treatment (p < 0.001) were significantly associated with glycemic control. Adherence of patients to regular follow up (Adjusted Odds Ratio (AOR) = 2.42, 95% CI 1.08–5.44, p = 0.03) and diabetes treatment for 5–10 years (AOR = 4.64, 95% CI 1.79–12.06, p = 0.002) are found to be independent predictors of glycemic control among type 2 diabetes patients.
TL;DR: Prudent drug use and improved hygienic practice is recommended in the dairy farms and abattoir to safeguard the public from the risk of acquiring infections and MDR pathogenic Staphylococcus.
Abstract: Staphylococcus species cause mastitis and wound infection in livestock and food poisoning in humans through ingestion of contaminated foods, including meat and dairy products. They are evolving pathogens in that they readily acquire drug resistance, and multiple drug-resistant (MDR) isolates are increasing in human and veterinary healthcare. Therefore, this study was conducted to evaluate the prevalence of Staphylococci and their drug resistance in dairy farms and abattoir settings of Addis Ababa. In this cross-sectional study, 193 samples of milk, meat, equipment and humans working in the dairy farms and abattoir were collected (dairy farms = 72 and abattoir sources = 121). Staphylococcus isolation and identification at the species level was done according to ISO-6888-3 using biochemical characteristics. An antimicrobial susceptibility test was conducted for 43 of the isolates using 15 antimicrobial agents commonly used for humans and livestock by the Kirby Bauer disk diffusion method following CLSI guidelines. Staphylococcus organism were isolated from 92 (47.7%) of the total 193 samples, 50% in the dairy farms and 46.3% in the abattoir. The isolated species were S. aureus (n = 31; 16.1%), S. intermedius (n = 21; 10.9%), S. hyicus (n = 16; 8.3%), and coagulase negative Staphylococcus (CNS) (n = 24; 12.4%). Gentamycin was effective drug as all isolates (n = 43; 100%) were susceptible to it and followed by kanamycin (n = 39; 90.7%). However, the majority of the isolates showed resistance to penicillin-G (95.3%), nalidixic acid (88.4%), cloxacillin (79.1%), vancomycin (65.1%) and cefoxitin (55.8%). Of the 15 S. aureus tested for drug susceptibility, 73.3% of them were phenotypically resistant to vancomycin (VRSA) and all of the 15 isolates showed multi-drug resistance (MDR) to >3 drugs. Also, all of the tested CNS (100%), S. hyicus (100%) and the majority of S. intermedius isolates (88.9%) developed MDR. Alarmingly, the Staphylococcus isolates circulating in the dairy farms and abattoir in the study area harbor MDR. High level of Staphylococcus species isolation from personnel and equipment besides food (meat and milk) samples in dairy farms and abattoir settings reveals that the hygiene practice in the dairy farm and abattoir is substandard. Prudent drug use and improved hygienic practice is recommended in the dairy farms and abattoir to safeguard the public from the risk of acquiring infections and MDR pathogenic Staphylococcus.
TL;DR: The prevalence of hypertension was high and may show a hidden epidemic in this population of adults aged 25–65 years and calls for efficient health screening and regular checkups as well as interventions promoting healthy lifestyles.
Abstract: Hypertension is a growing public health problem in many developing countries including Ethiopia. It is a silent killer and most patients are detected to have it incidentally when they are admitted to hospital for unrelated disease or subjected to pre-employment or preoperative medical checkups. Information on the prevalence of hypertension and its associated factors is to be considered vital to focus and improve prevention and control of cardiovascular diseases. The study design was a cross-sectional survey. The study population consisted of adults aged 25–65 years who lived in Jigjiga city of eastern Ethiopia for at least 6 months. Data were collected using a pretested structured questionnaire, and blood pressure was measured using standardized instruments by trained clinical nurses. Hypertension was defined as having Systolic BP ≥ 140 mmHg or Diastolic BP ≥ 90 mmHg or reported use of regular anti-hypertensive medications prescribed by professionals for raised BP. Data were entered into a computer using Epi Info Version 3.5.1 and exported to SPSS version 16.0 for analysis. Multiple logistic regressions were fitted and Odds ratios with 95% confidence intervals were calculated to identify independently associated factors. The prevalence of hypertension was 28.3%. Family history of Hypertension [Adjusted OR 5.7; 95% CI (2.9, 10.9)], having high level of income [Adjusted OR 3.1; 95% CI (1.5, 6.3)], being male [Adjusted OR 2.4; 95% CI (1.3, 4.3)], being above grade 12 [Adjusted OR 2.2; 95% CI (1.2, 3.9)], and having BMI ≥ 25 [Adjusted OR 2.0; 95% CI (1.1, 3.5)] were significantly associated with hypertension. Consistent with the literatures, the prevalence of hypertension was high and may show a hidden epidemic in this population. If established with more robust and nationally representative studies, the finding calls for efficient health screening and regular checkups as well as interventions promoting healthy lifestyles. Accordingly, health promotion regarding hypertension should be provided in the population as means of primary prevention.
TL;DR: Wide range of antibiotic resistance bacteria is prevalent in raw chicken meat, and ESBL producing Gram negative bacteria in chicken meat is found.
Abstract: Multidrug resistance (MDR) and extended spectrum beta lactamase (ESBL) producer Gram negative bacteria are considered as a major health problem, globally. ESBL enzyme hydrolyses the beta lactam ring of third generation cephalosporins, which alters the structure of the antibiotic. Due to the modification in structure of the antibiotic, bacteria show resistance to these antibiotics. Resistant bacterial strains are transmitted to humans from animals through consumption of uncooked meat, through contact with uncooked meat and meat surfaces. This study aims to assess bacteriological profile and analyze the situation of antibiotic resistance, multidrug resistance, and ESBL producing Gram negative bacteria in chicken meat. A total of 38 chicken meat samples were studied in which 103 Gram negative bacteria were isolated. Species of Gram negative bacteria were identified as Citrobacter spp. (44.7%), Salmonella spp. (26.2%), Proteus spp. (18.4%), Escherichia coli (4.8%), Shigella spp. (3.9%), Pseudomonas spp. (1.9%), and Klebsiella spp. (1.0%). The prevalence of MDR isolates was found to be 79.6%. Total ESBL producer was 36.9% and ESBL producer among MDR was 34.9%. This concludes wide range of antibiotic resistance bacteria is prevalent in raw chicken meat.
TL;DR: It is thus necessary to institute some personal and institutional strategies to ameliorate the effect of stress on the quality of life of pharmacy students while encouraging the use of positive stress management strategies.
Abstract: Stress among pharmacy students could greatly affect their learning activities and general well-being. It is therefore necessary to investigate how stress relates with the quality of life of students to maintain and/or improve their personal satisfaction and academic performance. A school-based longitudinal study was used to investigate the relationship between stress and quality of life of undergraduate pharmacy students. The 10-item perceived stress scale and the shorter version of the WHO quality of life scale were administered to the same participants at two time points i.e. Time 1 (4 weeks into the semester) and Time 2 (8 weeks afterwards). The correlations and differences between the study variables were tested using the Pearson’s coefficient and independent sample t test. The mean stress scores were higher at Time 2 compared to Time 1 for the first and second years. However, there was no significant difference in stress for different year groups—Time 1 [F (3) = 0.410; p = 0.746] and Time 2 [F(3) = 0.909; p = 0.439]. Female students had higher stress scores at Time 2 compared to male students. The main stressors identified in the study were; large volume of material to be studied (88.2%), laboratory report writing (78.2%), constant pressure to maintain good grades (66.4%) and the lack of leisure time (46.4%). Even though most students employed positive stress management strategies such as time management (68.2%), other students resorted to emotional eating (9.1%) and alcohol/substance use (1.8%). At Time 2, perceived stress scores were significantly negatively correlated with social relationship (r = −0.40, p ≤ 0.0001), environmental health (r = −0.37, p ≤ 0.0001), physical health (r = −0.49, p ≤ 0.0001) and psychological health (r = −0.51, p ≤ 0.0001). The study reported significant correlations between stress and various domains of quality of life of undergraduate pharmacy students. It is thus necessary to institute some personal and institutional strategies to ameliorate the effect of stress on the quality of life of pharmacy students while encouraging the use of positive stress management strategies.
TL;DR: Various bacterial infections linked with high levels of MDR bacteria pathogens are major health problems in the study area and treatment of common bacterial infections in theStudy area needs to be guided by drug-susceptibility testing of isolates.
Abstract: In developing countries like Ethiopia, infections with antibiotic resistant bacteria become a real threat. Hence, monitoring of local level antimicrobial resistance profile is indispensable to contain the spread of drug resistant bacteria and intervene poor awareness on antimicrobial resistance. Therefore, this study aimed at determining bacterial and antibiotic resistance profiles of infections from different sites that occurred among patients. Retrospective data recorded were analyzed on culture and drug susceptibility test results at Debre Markos Referral Hospital which were performed from 2011 to 2014. Drug susceptibility tests were performed using disk-diffusion technique. Chi square test was computed to compare the proportion of bacterial isolates with patients’ age and sex. Out of 575 clinical samples processed, 280 (48.7%) were culture positive for aerobic bacteria pathogens. Wound 238 (41.4%) and urine 108 (18.8%) were the most frequent samples processed. Overall, Staphylococcus aureus (S. aureus) was the predominant isolate 100 (31.5%) followed by Escherichia coli (E. coli) 39 (13.8%), Pseudomonas aeruginosa (P. aeruginosa) 30 (10.3%) and Salmonella spp. 25 (8.9%). P. aeruginosa was the most frequent isolate followed by S. aureus from ear infection. E. coli was the leading isolate followed by Klebsiella spp. from urinary tract infection. Salmonella and Shigella spp. were the most frequent isolates in stool in children below 5 years of age. Neisseria gonorrhoeae (N. gonorrhoeae) 16 (76.2%) was the most common isolate from urethral discharge. The overall multidrug-resistant Gram positive and Gram negative bacteria isolates were 113 (84.6%) and 96 (72.2%), respectively. Gram positive bacteria revealed resistance to cotrimoxazole (80%), gentamicin (83.1%), amoxicillin (85.1%), ampicillin (85.8%), penicillin (89.7%), clindamycin (93.2%) and erythromycin (90.9%). Gram negative bacteria showed resistance to cotrimoxazole (53.1%), amoxicillin (58.8%), ampicillin (70.4%), tetracycline (75.9%) and gentamicin (76.9%). Various bacterial infections linked with high levels of MDR bacteria pathogens are major health problems in the study area. Therefore, treatment of common bacterial infections in the study area needs to be guided by drug-susceptibility testing of isolates.
TL;DR: The prevalence of intestinal helminthic infection and anemia among pregnant women attending ANC in East Wollega Zone, Ethiopia was significantly high and different socio-demographic, lifestyle and obstetric factors were identified as significant contributors.
Abstract: Ethiopia is a developing country where intestinal helminthic infections are major public health problems. The burden of intestinal parasites, particularly the soil-transmitted helminths (STHs), is often very high in school children and pregnant women. Anemia, associated with STH, is a major factor in women’s health, especially during pregnancy; it is an important contributor to maternal mortality. The aim of this study was to determine the prevalence of intestinal helminthic infection and anemia among pregnant women attending ANC in East Wollega Zone, Ethiopia. A cross-sectional study was conducted in five health centers of East Wollega Zone of Oromia Region, Ethiopia between November 2015 and January 2016. The health centers were selected randomly and study participants were enrolled consecutively with proportions from all the health centers. Stool and blood specimens were processed using standard operating procedures in accordance with structured questionnaires. Logistic regression models were applied to assess the association between predictors and outcome variables. P values less than 0.05 were taken as significant levels. Results were presented in tables and figures. A total of 372 pregnant women were enrolled in this study with a median age of 25 years (range 17–40 years). The total prevalence of intestinal helminths was 24.7% (92/372) with the predominance of Hookworm (15.1%) followed by Ascaris lumbricoides (6.5%). Illiteracy [AOR, 95% CI 2.21 (1.3, 4.8), P = 0.042], absence of latrine [AOR, 95% CI 4.62 (1.7, 8.3), P = 0.013] and regular consumption of raw and/or unwashed fruit [AOR, 95% CI 3.30 (1.2, 6.3), P = 0.011] were significant predictors of intestinal helminthic infection. The overall prevalence of anemia was 17.5% (65/372) where mild anemia accounts for 80% of the total anemia. Anemia was significantly associated with the first trimester of gestation [AOR, 95% CI 2.82 (1.3, 6.2), P = 0.009], previous malaria infection [AOR, 95% CI 2.32 (1.3, 5.3), P = 0.003], failing to take iron supplements regularly [AOR, 95% CI 1.82 (1.1, 4.8), P = 0.022] and infection with intestinal helminths specifically with Hookworm (P = 0.001) and Ascaris lumbricoides (P = 0.022). The prevalence of intestinal helminths and anemia was significantly high in this study. Different socio-demographic, lifestyle and obstetric factors were identified as significant contributors of intestinal helminthic infection and anemia among pregnant women. Therefore, public health measures and intensive antenatal care services are vital to promoting safe pregnancy.
TL;DR: In this paper, a cross-sectional study was conducted from November 2015 to March 2016 to estimate the prevalence, to assess the risk factors and to isolate the major etiological agent of subclinical mastitis in Bishoftu town.
Abstract: A cross-sectional study was conducted from November 2015 to March 2016 to estimate the prevalence, to assess the risk factors and to isolate the major etiological agent of subclinical mastitis in Bishoftu town. The study was conducted on 262 cross breed lactating cows selected from 12 intensively managed dairy farms. California mastitis test (CMT) and bacteriological culture methods were used as diagnostic tools. From 262 cows examined, 105 (40.1%) and from 1048 quarters examined, 170 (16.1%) were positive for sub-clinical mastitis using CMT. All CMT positive samples were cultured for etiological agent identification. From 170 samples cultured, 153 were positive for known subclinical mastitis pathogens. The dominant bacteria isolated were Staphylococcus species from these Staphylococcus aureus (44.9%) was the major one followed by Streptococcus spp. (25.3%) and other gram negative enteric bacteria, Escherichia coli (8.8%). Age, body condition score, milk yield, and number of parity were considered as potential risk factors; among these, age and number of parity have statistically significance association with the occurrence of subclinical mastitis (P < 0.05) both in the CMT and the bacteriological tests.
TL;DR: Obesity, hypertriglyceridemia, and systolic hypertension are independently associated with impaired fasting glucose among adults and it is recommended that the community be aware of healthy life style, early screening, and maintain continuous follow up.
Abstract: Diabetes mellitus is becoming a big public health challenge, particularly in developing countries like Ethiopia. It is a manageable disease if early screening and follow up is made. However, as studies in Ethiopia are limited and unorganized, determining the magnitude of prediabetes and diabetes and identifying associated risk factors is quite essential. A community-based, cross-sectional study was conducted from February to April 2015 among adults (aged ≥20 years) in a rural Koladiba town. A multistage sampling technique was used to select a total of 392 study participants. Data were collected after a fully informed written consent was obtained from each participant. Demographic, behavioral, and clinical data were collected using a well-structured questionnaire. Multivariable logistic regression models were fitted to control the effect of confounders. Adjusted odds ratios (AOR) with their 95% confidence intervals (95% CI) were computed to measure associations. A p value of <0.05 was considered as statistically significant. The prevalence of impaired fasting glucose and undiagnosed diabetes mellitus were 12% (95% CI 9–16) and 2.3% (95% CI 1.1–4), respectively, in Koladiba. Overweight (AOR: 4.257, 95% CI 1.345–13.476), obesity (AOR: 5.26, 95% CI 1.138–24.316), hypertriglyceridemia (AOR: 2.83, 95% CI 1.451–5.521), and systolic hypertension (AOR: 3.858, 95% CI 1.62–9.189) were found to be independently associated with impaired fasting glucose. Positive family history of diabetes also showed a marginal association with impaired fasting glucose (p = 0.057). Male sex (p = 0.012) and hypertriglyceridemia (p = 0.030) were associated with undiagnosed diabetes mellitus. The prevalence of impaired fasting glucose and undiagnosed diabetes mellitus are found to be significant. Obesity, hypertriglyceridemia, and systolic hypertension are independently associated with impaired fasting glucose among adults. We recommend that the community be aware of healthy life style, early screening, and maintain continuous follow up.
TL;DR: The positive response and readiness amongst lay users for an HIVST in this context prototype suggests that there would be a ready and willing market for HIVST.
Abstract: The uptake of HIV testing has increased in sub-Saharan Africa over the past three decades. However, the proportion of people aware of their HIV status remains lower than required to change the pandemic. HIV self-testing (HIVST) may meet this gap. Assessment of readiness for and the acceptability of HIVST by lay users in South Africa is limited. This paper presents results from a formative study designed to assess the perceived usability and acceptability of HIVST among lay users using several self-test prototypes. Fifty lay users were purposively selected from rural and peri-urban KwaZulu-Natal, South Africa. Acceptability of HIVST was assessed using a simple post-test quantitative assessment tool addressing confidence, ease-of-use, intended future use and willingness to pay. In-depth qualitative interviews explored what participants felt about the HIVST and why, their willingness to recommend and how much they would pay for a test. The key finding is that there is high acceptability regardless of self-test prototype. Acceptability is framed by two domains: usability and perceived need. Perceived usability was explored through perceived ease of use, which, regardless of actual correct usage, was reported by many of the respondents. Acceptability is influenced by perceived need, expressed by many who felt that the need for the self-test to protect privacy and autonomy. Ease of access and widespread availability of the test, not at a significant cost, were also important factors. Many participants would recommend self-test use to others and also indicated that they would choose to conduct the test again if it was free while some also indicated being willing to buy a test. The positive response and readiness amongst lay users for an HIVST in this context prototype suggests that there would be a ready and willing market for HIVST. For scalability and sustainability usability, including access and availability that are here independent indications of acceptability, should be considered. So too should the desire for future use, as an additional factor pointing to acceptability. The results show high acceptability in all of these areas domains and a general interest in HIVST amongst lay users in a community in KwaZulu-Natal.
TL;DR: The data confirm the anti-bacterial and anti-fungal properties of R. communis and showed that the biologically relevant phytochemicals from the leaves of this plant can be extracted with the solvents aqueous, methanol and ethanol.
Abstract: Ricinus communis leaves are used in herbal preparations for treating candidiasis, skin and wound infections in Ghana. This study aimed at comparing the phytochemical profile of aqueous, methanol, petroleum ether, ethyl acetate and ethanolic extracts of the leaves of Ricinus communis and determine the growth inhibitory activities, bactericidal, bacteriostatic and fungicidal effects of the respective extracts on Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumonaie and Candida albicans. The aqueous, methanol and ethanol extracts were shown to contain most of the phytochemicals analyzed. All solvents extracts exhibited inhibitory activity against the growth of all microorganisms under study. The methanol extract showed highest zones of inhibition and was found to be statistically significant (P < 0.05) compared to other solvents extracts. All solvents extracts exhibited both bacteriostatic and bactericidal effects on the test organisms at varying concentration, with MIC values ranging from 3.13 to 25.0 mg/ml and MBCs were from 200 to 400 mg/ml. MFCs of Candida albicans was between 200 and 400 mg/l. Our data confirm the anti-bacterial and anti-fungal properties of R. communis and showed that the biologically relevant phytochemicals from the leaves of this plant can be extracted with the solvents aqueous, methanol and ethanol.
TL;DR: Residence, ANC follow up, history of excess menstrual bleeding and interpregnancy interval were statistically associated with anemia among the pregnant women, and working in the identified gaps could reduce the current burden of anemiaamong pregnant women in the study area.
Abstract: Anemia is a condition in which the number of red blood cells or their oxygen-carrying capacity is insufficient to meet physiologic needs, which varies by age, sex, altitude, smoking, and pregnancy status. The study aim is to determine the prevalence and factors associated with anemia among pregnant women attending a hospital in southern Ethiopia using a structured interview administered questionnaire. Facility-based cross-sectional study was conducted from March 01–April 30 2015 at Butajira General Hospital, Ethiopia. A total of 217 women responded to the questionnaire and provided blood and stool samples for analysis. Data were analyzed using Statistical packages for social sciences version 20 for windows. The overall burden of anemia in this study was 27.6%. Residence, ANC follow up, history of excess menstrual bleeding and interpregnancy interval were statistically associated with anemia among the pregnant women. Therefore, working in the identified gaps could reduce the current burden of anemia among pregnant women in the study area.
TL;DR: The study revealed relatively high prevalence of parasitic infections among the study population, suggesting that about three-quarters of the anaemic mothers are either single or co-infected with parasitic agents.
Abstract: Parasitic infections are of public health concern globally, particular among at risk groups such as pregnant women in developing countries. The presence of these parasites during pregnancy potentiate adverse effects to both the mother and the unborn baby. This study sought to establish the prevalence of some parasitic agents among antenatal attendees in the Dangme East District of Ghana. A cross-sectional prospective study was conduct between April and July, 2012. Venous blood specimens were collected from each participant for haemoglobin estimation and malaria microscopy. In addition participants’ early morning mid-stream urine and stool specimens were analyzed microscopically for parasitic agents. A total of 375 pregnant women were involved in the study, of which anaemia was present in 66.4% (249/375). However, parasitic infections associated anaemia prevalence was 49.6% (186/375). In all, 186 cases of parasitic infections were observed; 171 (44.0%) were single isolated infections while 15 (4.0%) were co-infections. Plasmodium species were significantly associated with anaemia (13.3%, χ2 = 23.290, p < 0.001). Also, the presence of Schistosoma haematobium (3.7%, χ2 = 7.267, p = 0.008), Schistosoma mansoni (5.3%, χ2 = 5.414, p = 0.023) and hookworm (3.7%, χ2 = 11.267, p = 0.008) were significantly associated with anaemia in pregnancy. Except where co-infections exist (3.7%, χ2 = 11.267, p = 0.001), the rest of the single infections were insignificantly associated with anaemia. Collectively, intestinal helminthes were predominantly significant with anaemia in pregnancy (p = 0.001, χ2 = 107.800). The study revealed relatively high prevalence of parasitic infections among the study population, suggesting that about three-quarters of the anaemic mothers are either single or co-infected with parasitic agents.
