Chronic Suppurative Otitis Media: Bacteriology and Drug Sensitivity Patterns at the Quirino Memorial Medical Center (2004-2005): A Preliminary Study

Abstract: Objectives: To identify the bacterial pathogens associated with chronic suppurative otitis media and their antimicrobial sensitivity and resistance Study Design: Cross-sectional survey Setting: The study was carried out from July 2004-July 2005 at the outpatient clinic of a government tertiary hospital. Number of subjects: A total of 32 patients (54 ears) with unilateral or bilateral active chronic suppurative otitis media. Results: Bacterial pathogens of 54 ear discharge samples from CSOM were studied. Among them, 42 (78%) were pure cultures and 9 (16.7%) were mixed, only 3 (5.6%) of the submitted samples had no growth. There were 42 pure isolates, the most common of which was Staphylococcus aureus 21 (50%), followed by Pseudomonas aeruginosa 14 (33.3%). Drug sensitivity pattern of Staphylococcus aureus showed that 61.9% were resistant to Penicillin while more than 90% were sensitive to Aminoglycosides and Clindamycin. Pseudomonas aeruginosa was resistant to penicillin in 64.3% of cases and Ciprofloxacin was active against pseudomonas in 85.7%. Conclusion: The most common bacterial pathogens from CSOM include Staphylococcus aureus and Pseudomonas aeruginosa. Majority of the isolates of Staphylococcus aureus were resistant to penicillin. Aminoglycosides, macrolides and quinolones were effective against most of the isolates of Staphylococcus aureus. Keywords: chronic otitis media, perforated tympanic membrane, chronic aural discharge

Cognitive Dysfunction in Asian Patients with Depression (CogDAD): A Cross-Sectional Study.

Abstract: Background Cognitive dysfunction is a predominant symptom of Major Depressive Disorder (MDD), contributing to functional impairment. Objective The primary objective of this study was to assess and describe perceived cognitive dysfunction amongst Asian patients diagnosed with MDD. The secondary objective was to explore the associations between depression severity, perceived cognitive dysfunction and functional disability. Methods This was a multi-country, multi-centre, cross-sectional study. Adults with a current episode of MDD were recruited from 9 university/general hospital clinics in Asia. During a single study visit, psychiatrists assessed depression severity (Clinical Global Impression-Severity, CGI-S); patients completed questionnaires assessing depression severity (Patient Health Questionnaire-9 items, PHQ-9), perceived cognitive dysfunction (Perceived Deficit Questionnaire-Depression, PDQ-D) and functional disability (Sheehan Disability Scale, SDS). Results Patients (n=664), predominantly women (66.3%), were aged 46.5±12.5 years, lived in urban areas (81.3%) and were employed (84.6%). 51.5% of patients were having their first depressive episode; 86.7% were receiving treatment; 82.2% had a current episode duration >8 weeks. Patients had mild-to-moderate depression (CGI-S=3.3±1.0; PHQ-9=11.3±6.9). Patients reported perceived cognitive dysfunction (PDQ-D=22.6±16.2) and functional disability (SDS=11.3±7.9). PHQ-9, PDQ-D and SDS were moderately-to-highly correlated (PHQ-9 and SDS: r=0.72; PHQ-9 and PDQ-D: r=0.69; PDQ-D and SDS, r=0.63). ANCOVA showed that after controlling for patient-reported depression severity (PHQ-9), perceived cognitive dysfunction (PDQ-D) was significantly associated with functional disability (SDS) (p Conclusions Asian patients with MDD reported perceived cognitive dysfunction. There is a need for physicians to evaluate cognitive dysfunction in the clinical setting in order to reach treatment goals, including functional recovery beyond remission of mood symptoms.

Child drowning prevention in the Philippines: the beginning of a conversation

Abstract: This study describes a process to explore factors which contribute to child-drowning deaths and allows the development of appropriate strategies to prevent similar deaths in a selected site in the Northern Philippines. Data collection techniques used in obtaining baseline data include: review of drowning mortality records; key informant interviews; focus group discussions; and community walk-throughs. Risk factors identified which could or did contribute to drowning events were: proximity to bodies of water; inadequate child supervision; lack of information/awareness of prevention strategies; and lack of drowning prevention programme(s). Measures on how to prevent drowning deaths were explored and initial interventions were implemented through a committee convened by the community. These interventions include: community education sessions; capability building measures; redesigning of community wells; development of playpens; and use of barriers. Community engagement is a crucial element in the development and implementation of any health programme. This study demonstrates that by engaging and working with the community action occurs, however, there is a need to conduct further evaluation activities to determine if the actions by the community continued beyond the project and have resulted in a decrease in drowning. One of the strengths of the process described is that it is culturally appropriate and site-specific and allows the community to find the solutions itself. Exploration and delivery of further projects in larger areas is required to reduce drowning in the Philippines. An imperative is the evaluation which will provide valuable information on whether barriers are a sustainable and acceptable means of prevention to the community in the long term.

COVID-19 outcomes of 10,881 patients: retrospective study of neurological symptoms and associated manifestations (Philippine CORONA Study).

Abstract: Our study aimed to determine the effects of new-onset neurological symptoms (NNS) on clinically relevant outcomes in hospitalized patients with COVID-19 infection. We conducted a nationwide, comparative, retrospective, cohort study among adult, hospitalized COVID-19 patients involving 37 hospital sites from various regions in the Philippines. We included a total of 10,881 patients with confirmed COVID-19 infection (2008 had NNS while 8873 did not have NNS). The adjusted hazard ratios (aHRs) for mortality among the mild and severe cases were significantly higher by 1.660 (95% CI 1.132-2.435) and by 1.352 (95% CI 1.042-1.752), respectively, in the NNS group compared to those in the non-NNS group. The aHRs for respiratory failure in the NNS group were significantly increased by 1.914 (95% CI 1.346-2.722), by 1.614 (95% CI 1.260-2.068), and by 1.234 (95% CI 1.089-1.398) among the mild, severe, and critical cases, respectively. The aHRs for ICU admission in the NNS group were still significantly higher by 1.973 (95% CI 1.457-2.673) and by 1.831 (95% CI 1.506-2.226) among the mild and severe cases, respectively. Patients who had NNS were not significantly associated with a longer duration of ventilator dependence (adjusted odds ratio (aOR) 0.954, 95% CI 0.772-1.179), longer ICU stay (aOR 0.983, 95% CI 0.772-1.252) and longer hospital admission (aOR 1.045, 95% CI 0.947-1.153). The presence of NNS significantly increases the risk of mortality, respiratory failure and ICU admission among COVID-19 patients.

Macrophage HIF-1α mediates obesity-related adipose tissue dysfunction via interleukin-1 receptor-associated kinase M

Abstract: Hypoxia leading to stabilization of hypoxia-inducible factor 1α (HIF-1α) serves as an early upstream initiator for adipose tissue (AT) dysfunction. Monocyte-derived macrophage infiltration in AT contributes to inflammation, fibrosis and obesity-related metabolic dysfunction. It was previously reported that myeloid cell-specific deletion of Hif-1α protected against high-fat diet (HFD)-induced AT dysfunction. Prolyl hydroxylases (PHDs) are key regulators of HIF-1α. We examined the effects of myeloid cell-specific upregulation and stabilization of Hif-1α via deletion of prolyl-hydroxylase 2 (Phd2) and whether interleukin-1 receptor associated kinase-M (Irak-M), a known downstream target of Hif-1α, contributes to Hif-1α-induced AT dysfunction. Our data show that with HFD, Hif-1α and Irak-M expressions were increased in the AT macrophages of Phd2flox/flox/LysMcre mice compared with LysMcre mice. With HFD, Phd2flox/flox/LysMcre mice exhibited increased AT inflammation, fibrosis, and systemic insulin resistance compared with control mice. Furthermore, Phd2flox/flox/LysMcre mice bone marrow-derived macrophages exposed to hypoxia in vitro also had increased expressions of both Hif-1α and Irak-M. In wild-type mice, HFD induced upregulation of both HIF-1a and Irak-M in adipose tissue. Despite equivalent expression of Hif-1α compared with wild-type mice, globally-deficient Irak-M mice fed a HFD exhibited less macrophage infiltration, decreased inflammation and fibrosis and improved glucose tolerance. Global Irak-M deficiency was associated with an alternatively-activated macrophage phenotype in the AT after HFD. Together, these data show for the first time that an Irak-M-dependent mechanism likely mediates obesity-related AT dysfunction in conjunction with Hif-1α upregulation.
