Mapping subnational HIV mortality in six Latin American countries with incomplete vital registration systems

Abstract: Background Human immunodeficiency virus (HIV) remains a public health priority in Latin America. While the burden of HIV is historically concentrated in urban areas and high-risk groups, subnational estimates that cover multiple countries and years are missing. This paucity is partially due to incomplete vital registration (VR) systems and statistical challenges related to estimating mortality rates in areas with low numbers of HIV deaths. In this analysis, we address this gap and provide novel estimates of the HIV mortality rate and the number of HIV deaths by age group, sex, and municipality in Brazil, Colombia, Costa Rica, Ecuador, Guatemala, and Mexico. Methods We performed an ecological study using VR data ranging from 2000 to 2017, dependent on individual country data availability. We modeled HIV mortality using a Bayesian spatially explicit mixed-effects regression model that incorporates prior information on VR completeness. We calibrated our results to the Global Burden of Disease Study 2017. Results All countries displayed over a 40-fold difference in HIV mortality between municipalities with the highest and lowest age-standardized HIV mortality rate in the last year of study for men, and over a 20-fold difference for women. Despite decreases in national HIV mortality in all countries—apart from Ecuador—across the period of study, we found broad variation in relative changes in HIV mortality at the municipality level and increasing relative inequality over time in all countries. In all six countries included in this analysis, 50% or more HIV deaths were concentrated in fewer than 10% of municipalities in the latest year of study. In addition, national age patterns reflected shifts in mortality to older age groups—the median age group among decedents ranged from 30 to 45 years of age at the municipality level in Brazil, Colombia, and Mexico in 2017. Conclusions Our subnational estimates of HIV mortality revealed significant spatial variation and diverging local trends in HIV mortality over time and by age. This analysis provides a framework for incorporating data and uncertainty from incomplete VR systems and can help guide more geographically precise public health intervention to support HIV-related care and reduce HIV-related deaths.

Social Media Use, Self-Efficacy, Perceived Threat, and Preventive Behavior in Times of COVID-19: Results of a Cross-Sectional Study in Pakistan

Abstract: Although the role of social media in infectious disease outbreaks is receiving increasing attention, little is known about the mechanisms by which social media use affects risk perception and preventive behaviors during such outbreaks. This study aims to determine whether there are any relationships between social media use, preventive behavior, perceived threat of coronavirus, self-efficacy, and socio-demographic characteristics. The data were collected from 310 respondents across Pakistan using an online cross-sectional survey. Reliability analyses were performed for all scales and structural equational modeling was used to identify the relationships between study variables. We found that: (i) social media use predicts self-efficacy (β = 0.25, p < 0.05) and perceived threat of coronavirus (β = 0.54, p < 0.05, R2 = 0.06), and (ii) preventive behavior is predicted by self-efficacy and perceived threat of coronavirus (R = 0.10, p < 0.05). Therefore, these results indicate the importance of social media's influence on health-related behaviors. These findings are valuable for health administrators, governments, policymakers, and social scientists, specifically for individuals whose situations are similar to those in Pakistan.

Anxiety amongst physicians during COVID-19: cross-sectional study in Pakistan.

Abstract: Ensuring safety and wellbeing of healthcare providers is crucial, particularly during times of a pandemic. In this study, we aim to identify the determinants of anxiety in physicians on duty in coronavirus wards or quarantine centers. We conducted a cross-sectional quantitative survey with an additional qualitative item. Five constructs of workload, exhaustion, family strain, feeling of protection, and anxiety were measured using items from two validated tools. Modifications were made for regional relevance. Factor analysis was performed showing satisfactory Cronbach alpha results. Overall, 103 physicians completed the questionnaire. T-test results revealed significant associations between gender and anxiety. Structural equation modeling identified that high workload contributed to greater exhaustion (β = 0.41, R2 = 0.17, p < 0.001) and greater family strain (β = 0.47, R2 = 0.22, p < 0.001). Exhaustion (β = 0.17, p < 0.005), family strain (β = 0.34, p < 0.001), and feelings of protection (β = − 0.30, p < 0.001) significantly explained anxiety (R2 = 0.28). Qualitative findings further identified specific needs of physicians with regard to protective equipment, compensation, quarantine management, resource allocation, security and public support, governance improvement, and health sector development. It is imperative to improve governmental and social support for physicians and other healthcare providers during the corona pandemic. Immediate attention is needed to reduce anxiety, workload, and family strain in frontline practitioners treating coronavirus patients, and to improve their (perceptions of) protection. This is a precondition for patient safety.

Cost savings associated with nutritional support in medical inpatients: an economic model based on data from a systematic review of randomised trials

Abstract: Background and aims Nutritional support improves clinical outcomes during hospitalisation as well as after discharge. Recently, a systematic review of 27 randomised, controlled trials showed that nutritional support was associated with lower rates of hospital readmissions and improved survival. In the present economic modelling study, we sought to determine whether in-hospital nutritional support would also return economic benefits. Methods The current economic model applied cost estimates to the outcome results from our recent systematic review of hospitalised patients. In the underlying meta-analysis, a total of 27 trials (n=6803 patients) were included. To calculate the economic impact of nutritional support, a Markov model was developed using transitions between relevant health states. Costs were estimated accounting for length of stay in a general hospital ward, hospital-acquired infections, readmissions and nutritional support. Six-month mortality was also considered. The estimated daily per-patient cost for in-hospital nutrition was US$6.23. Results Overall costs of care within the model timeframe of 6 months averaged US$63 227 per patient in the intervention group versus US$66 045 in the control group, which corresponds to per patient cost savings of US$2818. These cost savings were mainly due to reduced infection rate and shorter lengths of stay. We also calculated the costs to prevent a hospital-acquired infection and a non-elective readmission, that is, US$820 and US$733, respectively. The incremental cost per life-day gained was −US$1149 with 2.53 additional days. The sensitivity analyses for cost per quality-adjusted life day provided support for the original findings. Conclusions For medical inpatients who are malnourished or at nutritional risk, our findings showed that in-hospital nutritional support is a cost-effective way to reduce risk for readmissions, lower the frequency of hospital-associated infections, and improve survival rates.

Frequency and reasons for delayed treatment initiation after HIV diagnosis: cross-sectional study in Lahore, Pakistan

Abstract: Well-timed initiation of HIV therapy enhances life expectancy, decreases mortality and morbidity, and inhibits the transmission of HIV and complications related to it. The purpose of the present survey is to investigate the frequency and reasons for delayed initiation of anti-retroviral therapy (ART) and to determine its relationship with various socio-demographic variables and HIV-related characteristics. The analysis is based on a cross-sectional study involving 355 people living with HIV (diagnosed by PCR) who were more than 18 years of age and not receiving HIV therapy before enrolment at the HIV clinics of two selected tertiary-care teaching hospitals in Lahore, Pakistan. In this study, delayed initiation of ART was defined as not attending the HIV management centre or a clinic for ART within 3 months of a confirmed diagnosis. The participants were selected using a systematic probability sampling technique. Bivariate logistic regression was performed using a backward stepwise technique to establish the variables related to delayed onset of HIV therapy. Factors significant at p ≤ 0.20 were considered for multivariate analysis, which was used to describe the association between independent factors and delayed initiation of treatment. Delayed onset of ART was observed in 28.5% of individuals. Factors such as no schooling (AOR = 5.92; 95% CI: 1.38–25.41; p = 0.017) and occasional household income (AOR = 3.88; 95% CI: 1.01–14.89; p = 0.048) were significantly associated with late onset of ART. Our research findings also indicated that the main reasons for late beginning of HIV therapy were: feeling healthy (45.5%), did not have time to go to the HIV treatment centre (42.6%), did not want to discuss HIV test result (37.6%), and fear of stigma and discrimination within their community (35.6%). Late commencement of HIV therapy in Pakistan is common, and an improved connection is needed between identification of HIV and beginning of therapy. HIV management centres should counsel and monitor patients from the time of a positive HIV test result until they initiate therapy.

Psychosocial, emotional and professional challenges faced by female healthcare professionals during the COVID-19 outbreak in Lahore, Pakistan: a qualitative study.

Abstract: The novel coronavirus disease (COVID-19) is spreading rapidly, increasing the stress and challenges for healthcare professionals around the world. This study aims to discover the psychosocial, emotional and professional challenges faced by female healthcare professionals (HCPs) treating COVID-19 patients in Pakistan. Using an empirical phenomenological methodology, semi-structured telephone-based qualitative interviews were conducted with 22 female HCPs who were providing their expertise for COVID-19 patients in tertiary-level hospitals in Lahore, Pakistan. Purposive sampling was used for recruitment. The interviews were conducted between 20 July and 20 August 2020. The interviews were analysed using thematic analysis. This study explored the psychosocial, emotional and professional challenges faced by female HCPs serving COVID-19 patients. Five themes were observed in the interviews: apprehension while treating COVID-19 patients; feelings towards COVID-19 patients; challenges as female HCPs and coping strategies; confidence in government, administration and self-reflection; and finally, future concerns and recommendations. Many of these themes have also been linked with cultural issues, making the results specific to Pakistan. During the COVID-19 pandemic, female frontline HCPs have faced immense psychosocial pressure, ranging from unsupportive family norms to an unwelcoming working environment and insensitive hospital administrations. Moreover, rumours among the general public, lack of proper training, missing incentives and improper system surveillance have increased the anxiety and stress among HCPs. Hence, legislators are advised to take appropriate actions countrywide in order to alleviate the still ongoing challenges and support female HCPs in their working environment.

Factors shaping the COVID-19 epidemic curve: a multi-country analysis.

Abstract: Lockdown measures are the backbone of containment measures for the COVID-19 pandemic both in high-income countries (HICs) and low- and middle-income countries (LMICs). However, in view of the inevitably-occurring second and third global covid-19 wave, assessing the success and impact of containment measures on the epidemic curve of COVID-19 and people’s compliance with such measures is crucial for more effective policies. To determine the containment measures influencing the COVID-19 epidemic curve in nine targeted countries across high-, middle-, and low-income nations. Four HICs (Germany, Sweden, Italy, and South Korea) and five LMICs (Mexico, Colombia, India, Nigeria, and Nepal) were selected to assess the association using interrupted time series analysis of daily case numbers and deaths of COVID-19 considering the following factors: The “stringency index (SI)” indicating how tight the containment measures were implemented in each country; and the level of compliance with the prescribed measures using human mobility data. Additionally, a scoping review was conducted to contextualize the findings. Most countries implemented quite rigorous lockdown measures, particularly the LMICs (India, Nepal, and Colombia) following the model of HICs (Germany and Italy). Exceptions were Sweden and South Korea, which opted for different strategies. The compliance with the restrictions—measured as mobility related to home office, restraining from leisure activities, non-use of local transport and others—was generally good, except in Sweden and South Korea where the restrictions were limited. The endemic curves and time-series analysis showed that the containment measures were successful in HICs but not in LMICs. The imposed lockdown measures are alarming, particularly in resource-constrained settings where such measures are independent of the population segment, which drives the virus transmission. Methods for examining people’s movements or hardships that are caused by covid- no work, no food situation are inequitable. Novel and context-adapted approach of dealing with the COVID-19 crisis are therefore crucial.

The influence of social and cultural practices on maternal mortality: a qualitative study from South Punjab, Pakistan

Abstract: A disproportionately high rate of maternal deaths is reported in developing and underdeveloped regions of the world. Much of this is associated with social and cultural factors, which form barriers to women utilizing appropriate maternal healthcare. A huge body of research is available on maternal mortality in developing countries. Nevertheless, there is a lack of literature on the socio-cultural factors leading to maternal mortality within the context of the Three Delays Model. The current study aims to explore socio-cultural factors leading to a delay in seeking care in maternal healthcare in South Punjab, Pakistan. We used a qualitative method and performed three types of data collection with different target groups: (1) 60 key informant interviews with gynaecologists, (2) four focus group discussions with Lady Health Workers (LHWs), and (3) ten case studies among family members of deceased mothers. The study was conducted in Dera Ghazi Khan, situated in South Punjab, Pakistan. The data was analysed with the help of thematic analysis. The study identified that delay in seeking care—and the potentially resulting maternal mortality—is more likely to occur in Pakistan due to certain social and cultural factors. Poor socioeconomic status, limited knowledge about maternal care, and financial constraints among rural people were the main barriers to seeking care. The low status of women and male domination keeps women less empowered. The preference for traditional birth attendants results in maternal deaths. In addition, early marriages and lack of family planning, which are deeply entrenched in cultural values, religion and traditions—e.g., the influence of traditional or spiritual healers—prevented young girls from obtaining maternal healthcare. The prevalence of high maternal mortality is deeply alarming in Pakistan. The uphill struggle to reduce deaths among pregnant women is firmly rooted in addressing certain socio-cultural practices, which create constraints for women seeking maternal care. The focus on poverty reduction and enhancing decision-making power is essential for supporting women’s right to medical care. Round the world, many women are dying because of complications during pregnancy or in childbirth. These deaths are more frequent in developing and underdeveloped countries. Some reasons for this are related to social and cultural factors, which form barriers to women using appropriate maternal healthcare. Therefore, this study aims to explore socio-cultural factors leading to a delay in seeking maternal healthcare in South Punjab, Pakistan. We interviewed a variety of people to get an overview of this topic: (1) 60 interviews were conducted with gynaecologists, (2) we performed four focus group discussions with eight to ten Lady Health Workers providing maternal healthcare, and (3) we talked with family members of mothers who had died. The study shows that delays in seeking care are related to poor socioeconomic status, limited knowledge about maternal care, and low incomes of rural people. The low status of women and male domination keeps women less empowered. In addition, early marriages and lack of family planning due to cultural values, religion and traditions stopped young girls from getting maternal healthcare. The number of new mothers who die is very worrying in Pakistan. One of the important tasks for reducing deaths among pregnant women is to address certain socio-cultural practices. It is very important to reduce poverty and improve decision-making power to make sure women can use their right to medical care.

Sociocultural Challenges in the Implementation of COVID-19 Public Health Measures: Results From a Qualitative Study in Punjab, Pakistan.

Abstract: Informed public health measures are crucial to curb the COVID-19 pandemic. The sociocultural context is important to understand the success or failure of implementing public health measures. This study explores the social and behavioral response to COVID-19 and unveils challenges in the implementation of related public health measures in Pakistan. Within this qualitative study, we conducted 34 telephonic/online in-depth interviews with youths, adults, elderly people, and healthcare professionals in the Punjab province of Pakistan. Framework analysis was used for data analysis. People's poor understanding about COVID-19 and the need for preventive measures were the major challenge in implementing public health preventive strategies. Study participants reported that the lockdown strategy increased poverty and unemployment. People's poor living conditions and living environment compelled them not to follow social distancing and restricting themselves to home. Additionally, an underdeveloped healthcare system was one of the major challenges for Pakistan. The culture of denial in Pakistan related to the epidemiology of COVID-19 was an important challenge within the implementation of public health preventive measures. It is extremely important that public health experts and social scientists work together to understand the contextual sociocultural factors which shape behaviors associated with the spread of a pandemic.

Validation of the Multidimensional Assessment of Interoceptive Awareness (MAIA-2) questionnaire in hospitalized patients with major depressive disorder.

Abstract: Objectives Interoception refers to the sensation, interpretation, and integration of internal somatic signals. Abnormalities in self-reported interoception are prevalent features of major depressive disorder (MDD) and may affect treatment outcomes. In the present study, we investigated the psychometric properties of the revised eight-dimensional and 37-item Multidimensional Assessment of Interoceptive Awareness questionnaire (the MAIA-2) in a severely depressed sample, after translating two updated scales (Not-Distracting, Not-Worrying) into German. Specifically, we examined the measure's internal consistency reliability, sensitivity to change, and minimal important differences (MID) with a focus on patient's antidepressive responses to treatment. Methods The study enrolled 110 participants (age: M = 46.85, SD = 11.23; female: 55.45%) undergoing hospital treatment, of whom 87 were included in the pre-post analysis. Participants completed a German translation of MAIA-2 and the Beck Depression Inventory-II (pre-/post-treatment). Internal consistency reliability was determined by Cronbach's α/McDonalds's ω, sensitivity to change was determined by effect sizes, and MIDs were determined by distribution- (0.5*SD) and anchor-based approaches (mean change method; ROC curve cut-points). Results Depression severity reduced over the course of treatment (Median = -65.22%), and 34.48% of patients achieved remission. Reliability was appropriate for post-treatment (range of ω: .70-.90), but questionable for two pre-treatment scales (Noticing: ω = .64; Not-Distracting: ω = .66). The eight dimensions of MAIA-2 were sensitive to change (standardized response mean: .32-.81; Cohen's effect size: .30-.92). Distribution-based MIDs (.38-.61) and anchor-based mean change MIDs (remission vs. partial response: .00-.85; partial response vs. nonresponse: .08-.88) were established on the group level. For six scales, ROC cut-points (remission: .00-1.33; response: -.20-1.00) demonstrated accurate classification to treatment response groups on the individual level. Conclusions This study demonstrated the applicability of the MAIA-2 questionnaire in MDD. The updated version may have led to reliability improvements regarding the revised scales, but subthreshold reliability was evident prior to treatment. The measure's dimensions were sensitive to change. MIDs were established that corresponded with antidepressive treatment outcomes. Our findings are consistent with a growing area of research which considers somatic feelings as key contributors to mental health.

Tell me that I can do it better. The effect of attributional feedback from a learning technology on achievement emotions and performance and the moderating role of individual adaptive reactions to errors

Abstract: The study investigated whether and how the implementation of attributional feedback in a pen-tablet-based digital learning environment affects students' activity-related achievement emotions (enjoyment, boredom, anger, frustration) and writing performance. Furthermore, the role of students' tendency towards adaptive reactions to errors for the effect of attributional feedback on activity-related achievement emotions and performance, was examined. A total of 84 students were required to learn Japanese writing within a pen-tablet-based digital learning environment under one of two feedback design conditions: a condition with performance-based feedback only (PFC) or a condition adding attributional feedback (AFC). Students' tendency towards adaptive reactions to errors (i.e., affective-motivational and action-related adaptive reactions) were assessed as a baseline. Enjoyment, boredom, anger and frustration were measured at intervals during learning, while writing performance was measured continuously during the learning process. The results indicate that AFC students reported higher levels of enjoyment and lower levels of anger and frustration than those students who learned with the PFC within the digital learning environment. Furthermore, students who received the AFC outperformed the PFC students in writing performance. The results also show that the tendency towards an affective-motivational adaptive reaction to errors, was a significant positive predictor of enjoyment and writing performance and a negative predictor in terms of boredom, anger and frustration. In addition, a reduced tendency to maintain a positive effect and motivation to learn in the face of errors (i.e., affective-motivational tendency) enhanced the impact feedback design could have on anger and on frustration. In contrast, a stronger affective-motivational tendency helps to compensate the impact of feedback design on these negative, activity-related, achievement emotions. The results underline the necessity to take into account not only activity-related emotions, but also students' individual ways of dealing with errors, when designing feedback for digital learning environments.

Experiences of frontline Pakistani emigrant physicians combating COVID-19 in the United Kingdom: a qualitative phenomenological analysis.

Abstract: This study aims to explore the experiences, beliefs, feelings, and challenges faced by Pakistani migrant doctors working in the United Kingdom in times of the COVID-19 pandemic. The qualitative study aims to explore the lived experiences, beliefs, feelings, and challenges faced by Pakistani migrant physicians working in the United Kingdom during the COVID-19 pandemic. An exploratory phenomenological approach was used to collate data on experiences expressed during the COVID-19 pandemic. Purposive and snowball sampling was used to target participants, which were doctors of Pakistani origin involved in the direct care and management of COVID-19 patients in different NHS hospitals of the United Kingdom. Semi-structured, in-depth telephonic interviews were conducted with study participants in May 2020. Data analysis was done parallel with data collection by using an inductive qualitative approach. We recruited ten frontline physicians. Four theme categories emerged from the data analysis: 1) Working across borders and cultures, 2) Role of beliefs for coping with stress and fear, 3) Passion and profession, and 4) Scaffolding the Pakistani health system. Overall, the results show that the participants received limited professional support, in terms of counseling and psychological rehabilitation. Instead, they had to use self-management strategies to cope with the situation. The intensive work exhausted participants physically and emotionally. They were holding a lot of grief and hurt inside, but still, healthcare professionals showed the spirit of professional dedication to overcome difficulties. Although currently coping with their emotional problems, comprehensive professional support should be made available to cater to the wellbeing of frontline physicians.

Exploring online social networks of school leaders in times of COVID‐19

Abstract: The COVID-19 pandemic has raised a wide range of challenges for school leaders that they now (rapidly) have to address. Consequently, they also turn to informal learning networks, in order to share and collect information and reach out to their communities. In this context, the current study investigates the underlying networks structures among school leaders, what type of information is being shared, and what differences can be identified when comparing a nation-wide and a localized sample. We collected data from a US nation-wide sample of 15 relevant Twitter conversations, as well as Tweets from an US urban mid-sized public school district. Using a mixed-methods approach, we discovered several key structural dimensions and a host of highly influential actors. Moreover, we found semantic evidence for users sharing information on topics such as status reports. Finally, we discovered that the urban sample did not overly use the nation-wide, very specific approach of including COVID-19 related hashtags. Instead, they used more localized terminologies. These findings are valuable for policy makers, as they map the underlying communication patterns and provide valuable insights into who is moving what types of resources as part of the emerging governance approach on social media.

University students’ basic psychological needs, motivation, and vitality before and during COVID-19: A Self-Determination Theory approach

Abstract: Self-determination theory assumes that the basic psychological needs for autonomy, competence, and relatedness are associated with motivational regulation. As these basic psychological needs may have been affected by the shift to distance learning, students’ motivational regulation and vitality may have suffered as well. The purpose of this study was to examine the motivational regulation, satisfaction, or frustration of the basic psychological needs and vitality of university students before and after the transition to forced distance learning during the COVID-19 pandemic: Two student samples from Austria and Germany were studied: One was surveyed before the conversion to distance learning (N = 1,139) and the other at the beginning of forced distance learning (N = 1,835). The instruments used were the Scales for the Measurement of Motivational Regulation for Learning in University Students (SMR-L), the German version of the Basic Psychological Needs Satisfaction and Frustration Scale, a scale developed by the authors to differentiate the assessment of social relatedness, and the German version of the Subjective Vitality Scale. The results show that the satisfaction of basic psychological needs was significantly lower and the frustration thereof substantially higher during the distance learning period than before the pandemic. Intrinsic motivation and identified regulation were significantly lower during the forced distance learning period, and more controlled forms of motivation were higher than before the pandemic. Structural equation models showed that 42% of the students’ vitality can be explained by motivational regulation and the satisfaction and frustration of their basic needs. Motivational regulation styles functioned (differentiated according to the degree of autonomy) as mediating variables between basic needs and vitality. In terms of theoretical implications, the distinction between approach and avoidance components of introjected regulation was shown to be adequate and necessary, as they explain the outcome vitality differently. The support and avoidance of frustration of basic psychological needs should be considered in distance learning to promote the quality of motivation and students' vitality.

Determinants of women's empowerment in Pakistan: evidence from Demographic and Health Surveys, 2012-13 and 2017-18.

Abstract: Women’s empowerment has always remained a contested issue in the complex socio-demographic and cultural milieu of Pakistani society. Women are ranked lower than men on all vital human development indicators. Therefore, studying various determinants of women’s empowerment is urgently needed in the Pakistani context. The study empirically operationalized the concept of women’s empowerment and investigated its determinants through representative secondary data taken from the Pakistan Demographic and Health Surveys among women at reproductive age (15–49 years) in 2012–13 (n = 13,558) and 2017–18 (n = 15,068). The study used simple binary logistic and multivariable regression analyses. The results of the binary logistic regression highlighted that almost all of the selected demographic, economic, social, and access to information variables were significantly associated with women’s empowerment (p < 0.05) in both PDHS datasets. In the multivariable regression analysis, the adjusted odds ratios highlighted that reproductive-age women in higher age groups having children, with a higher level of education and wealth index, involved in skilled work, who were the head of household, and had access to information were reported to be more empowered. Results of the multivariable regression analysis conducted separately for two empowerment indicators (decision-making and ownership) corroborated the findings of the one indicator of women empowerment, except where ownership did not appear to be significantly associated with number of children and sex of household head in both data sets (2012–13 and 2017–18). A number of social, economic, demographic, familial, and information-exposure factors determine women’s empowerment. The study proposes some evidence-based policy options to improve the status of women in Pakistan.

Feedstock particle size distribution and water content dynamic in a pellet mill production process and comparative sieving performance of horizontal 3.15-mm mesh and 3.15-mm hole sieves

Abstract: Pellet feedstock particle size distribution is the main factor affecting pellet quality. Feedstock samples were obtained from different places in the production process of a commercial pellet mill. Particle size distribution and water content of the sieved particle fractions were analyzed. The results showed an alternation of particle size distribution and water content of the feedstock induced by the processing in the mill. Storage had a balancing effect on the water content distribution between the different particle size classes. Further experiments evaluated the reason for the underrepresentation of the 2.8–3.15-mm fraction in the feedstock. It was found that the major sieving factor for non-spherical wood particles was their width rather than their length, though the aspect ratio was important for the sorting between the 2.8–3.15-mm and the 2.0–2.8-mm sieve fractions. The significant differences between the particle width in the sieve fractions and the distribution of the particle aspect ratio improved when using a 3.15-mm mesh sieve instead of the 3.15-mm hole sieve. This indicates the better sieving performance of the 3.15-mm mesh sieve, which should be considered by pellet manufacturers and researchers investigating pellet feedstock.

Verfügbarkeit und Zielsetzungen digitalisierungsbezogener Lehrkräftefortbildungen für naturwissenschaftliche Lehrkräfte in Deutschland

Abstract: Lehrkrafte sind essentiell fur die Integration digitaler Technologien in Schule und Unterricht. Ihre Qualifizierung fur diese Aufgabe ist daher in allen Phasen der Lehrkrafteausbildung von zentraler Bedeutung, zumal nur etwa ein Drittel der derzeit im aktiven Schuldienst befindlichen Lehrkrafte wahrend des Studiums Lerngelegenheiten zu einem digitalisierungsbezogenen Kompetenzaufbau hatte. Trotz des Wunsches nach einer digitalisierungsbezogenen Qualifikation besuchen deutsche Lehrkrafte jedoch vergleichsweise selten Fortbildungen. Neben fehlender Passung des Fortbildungsangebots konnte fur diese Diskrepanz ein unzureichendes Angebot verantwortlich sein. Wir untersuchen in dieser Studie, welche Fortbildungsangebote in 12 von 16 Bundeslandern explizit fur naturwissenschaftliche Lehrkrafte uber staatliche Fortbildungskataloge angeboten wurden, welche Kompetenzbereiche des Orientierungsrahmens „Digitale Kompetenzen fur das Lehramt in den Naturwissenschaften“ (DiKoLAN) die Fortbildungen adressieren und inwieweit die in den Fortbildungen adressierten didaktischen Funktionen die Lehrkrafte bei der Ausbringung von Distanzunterricht wahrend der Schulschliesungen 2020 hatten unterstutzen konnen. Insgesamt werden 90 Fortbildungen identifiziert und damit zu wenige, um die Zielsetzungen der Kultusminister Konferenz-Strategie „Bildung in der digitalen Welt“ angemessen zu verfolgen. Aus den Angeboten lassen sich kaum Hinweise auf Faktoren ablesen, die der individuellen Lehrkraft einen kumulativen Kompetenzaufbau ermoglichen. Fast alle Fortbildungsangebote adressieren fur Naturwissenschaftslehrkrafte relevante Kompetenzbereiche des DiKoLAN-Orientierungsrahmens, ein Teil ist geeignet, Lehrkrafte die didaktischen Funktionen zu vermitteln, die auch bei der Ausbringung von Distanzunterricht genutzt werden konnen.

Digital health literacy intervention to support maternal, child and family health in primary healthcare settings of Pakistan during the age of coronavirus: study protocol for a randomised controlled trial.

Abstract: Introduction There is a need to continue primary healthcare services through digital communication for disadvantaged women living in underdeveloped areas of Pakistan, especially in the age of the coronavirus pandemic, social distancing and lockdown of communities. This project will be the first of its kind in aiming to implement a digital health literacy intervention, using smartphone and internet, to disadvantaged women through female community healthcare workers. Improved health literacy in women of reproductive years is known to promote maternal, child and family health overall. Methods and analysis The study will include a baseline survey, a pre- and post-test survey and a 3-month lasting intervention on (1) hygiene and prevention and (2) coronavirus awareness and prevention. Women of reproductive years will be sampled from disadvantaged areas across the four provinces of Pakistan (Baluchistan, Khyber Pakhtunkhwa, Punjab and Sindh), and the selection criteria will be poor, semiliterate or illiterate, belonging to underdeveloped neighbourhoods devoid of universal healthcare coverage and dependent on free primary health services. A target of 1000 women will comprise the sample, with 500 women each assigned randomly to the intervention and control groups. Analysis of variance and multivariate analysis will be used for analysing the intervention’s effects compared with the control group. Ethics and dissemination Ethics approval for this study has been received from the Internal Review Board of the Forman Christian College University (reference number: IRB-252/06-2020). Results will be published in academic journals of repute and dissemination to the international scientific community and stakeholders will also be planned through workshops. Trial registration number NCT04603092.

Psychosocial effects of the COVID-19 pandemic and lockdown on university students: Understanding apprehensions through a phenomenographic approach.

Abstract: Limited evidence exists to help understand the experiences of university students in relation to the long-term lockdown due to the COVID-19 pandemic. For that reason, we conducted a study using a phenomenographic approach in order to understand how university students perceive COVID-19 and the associated lockdown. Data were collected from 25 students in Pakistan. They were asked to demonstrate the psychological effects of the COVID-19 pandemic and lockdown in illustrations. In addition, in-depth interviews were conducted with these students, to gain further insights into their perspectives on the psychosocial effects of the COVID-19 pandemic. The analysis revealed four interlinked directions for understanding students' experiences. These themes were: 1) escape into peace, 2) hope for personal freedom, 3) fear of becoming a victim of COVID-19, and 4) concerns regarding education, future career, and opportunities. All four themes were analyzed and condensed into an outcome space, which further gathers the perceptions of students under one theme as "Hope for life while paradoxically living with fear". Studying the psychological impact of the COVID-19 pandemic and lockdown on students not only highlighted their concerns, but also emphasized the importance of starting regular psychological evaluations and stress-releasing sessions, along with online education to overcome growing depression.

Challenges in providing surgical procedures during the COVID-19 pandemic: Qualitative study among Operating Department Practitioners in Pakistan.

Abstract: The surgical theatre is associated with the highest mortality rates since the onslaught of the COVID-19 pandemic. However, Operating Department Practitioners (ODPs) are neglected human resources for health in regards to both professional development and research for patient safety; even though they are key practitioners with respect to infection control during surgeries. Therefore, this study aims to describe challenges faced by ODPs during the pandemic. The secondary aim is to use empirical evidence to inform the public health sector management about both ODP professional development and improvement in surgical procedures, with a specific focus on pandemics. A qualitative study has been conducted. Data collection was based on an interview guide with open-ended questions. Interviews with 39 ODPs in public sector teaching hospitals of Pakistan who have been working during the COVID-19 pandemic were part of the analysis. Content analysis was used to generate themes. Ten themes related to challenges faced by ODPs in delivering services during the pandemic for securing patient safety were identified: (i) Disparity in training for prevention of COVID-19; (ii) Shortcomings in COVID-19 testing; (iii) Supply shortages of personal protective equipment; (iv) Challenges in maintaining physical distance and prevention protocols; (v) Human resource shortages and role burden; (vi) Problems with hospital administration; (vii) Exclusion and hierarchy; (viii) Teamwork limitations and other communication issues; (ix) Error Management; and (x) Anxiety and fear. The public health sector, in Pakistan and other developing regions, needs to invest in the professional development of ODPs and improve resources and structures for surgical procedures, during pandemics and otherwise.
