RATIONALE AND OBJECTIVES

The COVID- 19 pandemic and the subsequent designation of the Philippine General Hospital lead to necessary adjustments in internal medicine residency training. This study investigated the impact of the COVID-19 pandemic on internal medicine (IM) residents in the Philippine General Hospital.

A questionnaire was developed and distributed among internal medicine residents employed in the years 2020 and 2021. Qualitative data was then gathered through on line and face-to-face interviews.

A total of 43 Internal Medicine residents responded. This study found that the pandemic significantly affected internal medicine residents and their overall training. The participants reported changes in the number and profile of patients seen, the limited outpatient clinical exposure, the difficulties of telemedicine, and the reduced interactions with consultants and subspecialty fellows. Infection control protocols and workforce limitations also affected the number of procedures done by the residents. Resident participants reported that they were able to allot more time to studying from the textbook because of the skeletal schedules and decreased number of patients. Other learning avenues were shifted to online conferences and lectures.

The COVID-19 pandemic a lso brought about changes in residents' day-to-day routines, schedules, and rotations. Communicating with patients and relatives was also reported to be more difficult. Lifestyle changes varied among resident s. Socialization also shifted to online avenues and social messaging platforms. Having colleagues who test positive tor COVID and subsequently requiring quarantine lead to constant changes in workforce dynamics. This lead to feelings of anxiety and isolation among its trainees.

However, a number of participants still believed that the pandemic allowed them to become better physicians. This was brought about by a sense of service and pride, camaraderie among colleagues, commitment to finishing the program, financial stability, and administrative support. Still, the participants stated areas for improvement, including more consistent protocol measures, additional financial compensation, added workforce, and more transparent administrative support. All in all, participants felt that they were still able to meet the learning outcomes and minimum competencies. Majority of the participants believed the experiences brought about by the pandemic helped them become a better internist.

Ultimately, the new challenges from the pandemic strengthened the sense of service, resilience and clinical acumen of the residents.

BACKGROUND

Community pharmacists play a strategic and indispensable role as healthcare professionals with direct patient access during the COVID-19 pandemic. Nevertheless, there had been no studies that document the challenges, adaptive measures, and opportunities of community pharmacy practice in the country during such period.

This study aimed to describe the challenges encountered and adaptive measures implemented by community pharmacies, and to explore opportunities of community pharmacy practice brought about by the COVID-19 pandemic in the Philippines.

The study employed a qualitative, cross-sectional study design. Convenience sampling was conducted representative of chain and independent drug stores, online and other stores with service variations, and pharmacy organizations. Recruitment was pursued until data saturation with a total of 16 participants. Interviews were transcribed and analyzed through thematic analysis using NVivo 12. The study received ethical clearance for implementation from the UP Manila Research Ethics Board.

Results showed there were various challenges that affected both the supply- and demand- side of pharmacy operations in the community pharmacy practice during the pandemic. Due to the adaptive role of the pharmacy profession during the pandemic, there has been an increased relevance of pharmacists in public health. Furthermore, the pandemic has exhibited the need to shift to the use of e-prescriptions. However, there are limitations to its current use, such as ensuring the validity of the prescription when presented in a pharmacy.

There are several challenges encountered by community pharmacists during the pandemic. These challenges led to several adaptive measures being implemented that also became an opportunity to emphasize the vital role community pharmacists play in the healthcare system.

Contarini’s syndrome refers to the occurrence of bilateral pleural effusion which has different causes for each hemithorax. Based on extensive literature search, this is a rare finding and to date, only two published cases have recorded tuberculous effusion on one side. In this paper, the authors aim to present a case of Contarini’s syndrome, and to give emphasis that such condition with different etiologies exists and should be considered in managing bilateral effusion. This is a case of a 69-year-old female with a 7-week history of dyspnea, 2-pillow orthopnea, fever, and right-sided chest discomfort. Patient sought consultation and was prescribed with Diclofenac and Cefalexin with no relief. Patient was then admitted and intubated due to worsening dyspnea. Patient was managed as COVID-19 confirmed critical with viral myocarditis, CAP-HR, and diabetic ketoacidosis. Initial chest x-ray showed right-sided pleural effusion. Thoracentesis was done and revealed exudative pleural fluid (PF) with WBC of 20,000 with neutrophilic predominance and negative RT-PCR MTB. Cytology revealed acute inflammatory pattern. Klebsiella pneumoniae ESBL was isolated. Antibiotics were shifted to levofloxacin and meropenem. Repeat chest x-ray showed left-sided pleural effusion. Thoracentesis was done and revealed exudative PF with WBC of 1,680 with neutrophilic predominance. No organism was isolated. RT-PCR for MTB was detected. Thus, anti-TB therapy was initiated. However, ETA TB culture showed resistance to isoniazid, rifampicin, and pyrazinamide. Patient was referred to PMDT for MDR-TB treatment. Bilateral effusion has resolved with no recurrence, and with uneventful removal of bilateral chest tubes. Patient was eventually extubated and transferred to the ward. Patient however developed HAP, was re-intubated and eventually expired due to the septic shock from VAP. This case report highlights the importance of weighing risk versus benefit in deciding to perform bilateral thoracentesis when there is a clinical suspicion of an alternate or concurrent diagnosis.

Fangcang shelter hospitals are modular, rapidly deployable facilities that play a vital role in pandemic response by providing centralized isolation and basic medical care for large patient populations. Artificial intelligence (AI) has the potential to transform Fangcang shelter hospitals into intelligent, responsive systems that are capable of significantly improving emergency preparedness, operational efficiency, and patient outcomes. Key application areas include site selection and design optimization, clinical decision support, AI-assisted clinical documentation and patient engagement, intelligent robotics, and operational management. However, realizing AI's full potential requires overcoming several challenges, including limited data accessibility, privacy and governance concerns, inadequate algorithmic adaptability in dynamic emergency settings, insufficient transparency and accountability in AI-driven decisions, fragmented system architectures due to proprietary formats, high costs disproportionate to the temporary nature of Fangcang shelter hospitals, and hardware reliability in austere environments. Addressing these challenges demands standardized data-sharing frameworks, development of explainable and robust AI algorithms, clear ethical and legal oversight, interoperable modular system designs, and active collaboration among multidisciplinary stakeholders.

Neutralizing antibodies have been designed to specifically target and bind to the receptor binding domain (RBD) of spike (S) protein to block severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus from attaching to angiotensin converting enzyme 2 (ACE2). This study reports a distinctive nanobody, designated as VHH21, that directly catalyzes the S-trimer into an irreversible transition state through postfusion conformational changes. Derived from camels immunized with multiple antigens, a set of nanobodies with high affinity for the S1 protein displays abilities to neutralize pseudovirion infections with a broad resistance to variants of concern of SARS-CoV-2, including SARS-CoV and BatRaTG13. Importantly, a super-resolution screening and analysis platform based on visual fluorescence probes was designed and applied to monitor single proteins and protein subunits. A spontaneously occurring dimeric form of VHH21 was obtained to rapidly destroy the S-trimer. Structural analysis via cryogenic electron microscopy revealed that VHH21 targets specific conserved epitopes on the S protein, distinct from the ACE2 binding site on the RBD, which destabilizes the fusion process. This research highlights the potential of VHH21 as an abzyme-like nanobody (nanoabzyme) possessing broad-spectrum binding capabilities and highly effective anti-viral properties and offers a promising strategy for combating coronavirus outbreaks.

BACKGROUND

The Philippines has been significantly affected by the HIV epidemic in the Asia-Pacific region, with a notable increase in new cases over the past decade. Despite efforts to promote HIV testing, access to treatment, and awareness campaigns, progress has been slow, particularly among youths. Tangere, a market research application, conducted surveys during and after the COVID-19 pandemic to assess HIV knowledge among Filipinos.

This study aimed to evaluate changes in HIV awareness among young Filipinos during and after the COVID-19 pandemic using data collected via Tangere’s surveys. Specifically, it sought to analyze demographic characteristics, sources of HIV information, and knowledge regarding HIV transmission, prevention, and stigma.

Tangere collaborated with the investigators to develop a questionnaire assessing HIV knowledge among young Filipinos. Surveys were conducted during and after the COVID-19 pandemic, targeting subscribers aged 18-35 years, primarily from the National Capital Region and Luzon area. Data analysis involved calculating frequencies and percentages to summarize demographic characteristics and HIV knowledge. An Independent-Samples Proportions procedure was used to compare HIV knowledge during and after the pandemic.

The survey revealed that while respondents generally possessed reasonable knowledge about HIV, there were notable changes in the awareness during and after the pandemic. Social media and television were identified as primary sources of HIV information. Knowledge regarding HIV transmission and prevention increased postpandemic, particularly concerning preventive measures such as pre-exposure prophylaxis (PREP) and motherto-child transmission (MTCT). However, persistent misconceptions and stigma surrounding HIV remained, indicating the need for continued education and advocacy efforts.

The study underscores the importance of utilizing social media platforms for HIV awareness campaigns, especially among youths who are disproportionately affected by the epidemic. Despite improvements in knowledge, the Philippines has yet to achieve global HIV prevention goals. Continued efforts to enhance awareness, particularly regarding recent advancements in HIV prevention and treatment, are essential for curbing the epidemic and improving public health outcomes nationwide.

BACKGROUND

The occurrence of the COVID-19 pandemic resulted in increased risk of developing antimicrobial resistance due to the high utilization of antimicrobial agents. Since antimicrobial utilization is a crucial driver in the development of antimicrobial resistance, the need for antimicrobial use surveillance is crucial in identifying prescription patterns that would help provide proper interventions.

To determine the antibiotic use and prevalence of prescription quality indicators among COVID-19 patients admitted at a tertiary government hospital.

A retrospective cross-sectional survey was conducted to provide data on antibiotic use and the prevalence of prescription quality indicators among COVID-19 patients in a tertiary-level hospital from June 2021 to June 2022.

A total of 342 patient medical records were surveyed. The majority (119, 34.8%) of the patients were in the age group 41-60 years old and there were more male patients (52.34%) than female patients (47.66%). About 88.99% of the patients were considered to have community-acquired COVID-19 infections. Co-morbidities among patients were seen in more than half of the surveyed population (64%). These include hypertension, diabetes mellitus, chronic kidney disease, coronary artery disease, chronic lung disease, and hematologic disorders.

Empiric antibiotic therapy was high at 88.88%, while definitive treatment with confirmed bacterial infection was only at 11.11%. The most frequently prescribed antibiotic therapies are azithromycin (250, 45.9%), ceftriaxone (188, 32.2%), and cefuroxime (58, 9.9%). Patterns of antibiotic use are attributed to the similarities of respiratory bacterial infections with COVID-19 cases.

Prescription quality indicators assessed in the study include documentation of indication for prescriptions, guideline compliance, collection of culture before antibiotic therapy, and stop/review documentation. Out of 583 antibiotic prescriptions, 464 (79.58%) were properly documented with an indication. Non-compliance to guidelines reached 39.11%, while the stop and review date documentation rate was 20.41%. The collection of culture before the start of antibiotic therapy was at 50.2%.

The results from the study highlighted the need for antimicrobial surveillance and stewardship efforts among COVID-19 and other viral infections.

BACKGROUND AND OBJECTIVES

COVID-19 has quickly spread over the world and became an unprecedented burden on health care systems. COVID-19 diagnosis necessitates the use of precise testing methods such as RT-PCR. This method is generally reported as positive or negative, however, studies have shown its semi-quantitative capability through Ct values. This study determined an association that exists between the Ct values, clinical features, and laboratory findings among COVID-19 patients admitted in a tertiary infectious disease hospital in Manila, Philippines. This attempts to further explore the utility of RT-PCR in disease severity classification and diagnosis.

This was an observational retrospective study that utilized a purposive sampling method, wherein patients were selected based on the DOH case definition of confirmed COVID-19, and were stratified according to disease severity. Baseline laboratory data of the patients were gathered from medical records covering the period of June 2021 to January 2022 using a Data Collection Form. Chi-square test was used to measure the degree of association between the groups and categorical variables. Regression Analysis was used to identify predictors for certain variables. SPSS Statistics for Windows, Version 25.0 was utilized for the statistical analysis.

The total WBC, neutrophil, lymphocyte and monocyte counts, serum urea, LDH, CRP and PTT were found to be predictors of COVID-19 severity. There was no significant difference observed between the disease severity and the patient’s clinical outcome. All routine laboratory tests that were taken at baseline (ORF Gene, N-Gene, Hematocrit, White Blood Cells, Neutrophil, Lymphocyte, Monocyte, Platelet Count, Urea, Creatinine, SGPT, SGOT, Na, K, LDH, Ferritin, C Reactive Protein, Procalcitonin, D-Dimer, PT, PTT) were not significant predictors of the clinical outcome. Although WBC, neutrophil, lymphocyte, and monocyte count, urea, LDH, CRP, and PTT were predictors  of disease severity. The study also reported that the odds of having severe to critical disease increases by 20.6% for every one unit increase in neutrophil count, and 17.4% for every one unit increase in lymphocyte count. Among the laboratory parameters, neutrophil count (p=0.010654063) and urea (p= 0.04149874 have direct relationship with the N gene Ct values while Orf gene Ct Values have direct relationship with lymphocyte count (p=0.01269027). Similarly, regression showed that as monocyte count, creatinine levels, and serum ferritin decrease, Ct values increase. Sex was found to not be a significant predictor of disease severity and clinical outcome. There was also no significant difference observed between the disease severity and the patient’s clinical outcome.

The study showed that the Ct values for both ORF and N genes were not significant predictors of both disease severity and clinical outcome. However, ORF gene Ct values have direct relationship with lymphocyte counts while N gene Ct values have direct correlation with neutrophil count and urea levels. Similarly, monocyte, creatinine, and ferritin are negatively correlated with Ct values. It is important to monitor the patient’s laboratory biomarkers in order to determine the proper course of treatment and management for each case.
