BACKGROUND

Coronavirus Disease 2019 (COVID-19), caused by the SARS-CoV-2 virus, presents not only as a respiratory ailment but also poses risks of neurological complications whose underlying mechanisms remain unclear. These complications range from mild to severe and may involve direct invasion of the central nervous system (CNS), disruption of the blood-brain barrier, or systemic cytokine effects. Diagnostic challenges persist due to the suboptimal sensitivity of RT-PCR assays.

The present study aimed to review the contrast and non-contrast enhanced cranial CT images of all diagnosed COVID-19 patients in a tertiary referral center with the clinical impression of non-traumatic and nonoperative CNS pathologies.

We conducted a cross-sectional study analyzing CT images of COVID-19 patients with neurological symptoms. Among 51 included patients, plain CT scans were predominantly used, revealing no acute infarcts or hemorrhages in the majority, while frontal lobe involvement was notable in cases with pathology. Chronic infarcts or ischemic changes were observed in over half of the cases, primarily affecting the anterior circulation. Only one case of meningitis was documented.

In the final analysis, 51 patients met the inclusion criteria out of the initial 64 enrolled. The study population, predominantly male with a mean age of 58.02 ± 20.87 years, mainly comprised patients solely diagnosed with COVID-19. Plain CT scans were favored over contrast-enhanced scans (76.50%, n = 39). While most patients had no acute infarcts or hemorrhages, the frontal lobe was commonly affected among stroke patients (9.8%, n = 5). Additionally, a significant portion of patients without acute stroke findings exhibited chronic infarcts or ischemic changes (57.69%, n = 15).

This study sheds light on the radiological patterns of CNS involvement in COVID-19 patients, highlighting frequent frontal lobe involvement possibly attributed to hypercoagulability and endotheliitis. Further research with larger sample sizes and MRI utilization is recommended to enhance our understanding of CNS manifestations in COVID-19. This study contributes to understanding COVID-19 neurological sequelae, particularly in terms of radiological patterns, among patients presenting with neurological symptoms. The findings highlight the need for comprehensive evaluation and management of neurological complications in COVID-19 patients.

OBJECTIVES

The study aimed to define the cycle threshold (Ct) value of reverse transcription polymerase reaction (RT PCR) as a potential marker in identifying the risk of COVID-19-confirmed patients in developing cerebrovascular disease (CVD) and to present the risk factors associated with such occurrence.

The researcher employed a single center, retrospective, chart review, case-control study among adult RT-PCR confirmed, hospitalized COVID-19 patients at Las Piñas General Hospital and Satellite Trauma Center (LPGH STC) from January to December 2021. The study included 252 patients among 730 RT-PCR-confirmed adult COVID-19 patients who met the study population criteria.

Fifty patients had concomitant CVD, while 202 patients were non-CVD. The majority (n=143, 56.75%) were 19-59 years old male predominance (n=138, 54.76%). More than half of the study population suffered from either hypertension, diabetes, or both, with a high proportion of the subjects being non-compliant or no maintenance medications. Two hundred ten (83.3%) out of 252 patients were unvaccinated. Twenty (7.9%) patients were noted with a history of smoking, and 58 (23%) patients with a history of alcohol intake. The majority of the patients suffered moderate COVID-19 severity during their hospital stay, with a 30.16% (n=76) mortality rate. Ischemic stroke was the most common CVD, with 38 (76%) occurrences. Acute respiratory failure was the leading cause of death, followed by ARDS, brainstem failure, and ACS. The median cycle threshold among CVD patients was 32.84, significantly higher than the majority at 28.64. A higher mean Ct value was noted among patients with CVD infarct at 33.44 as compared to 26.83 among patients with Hemorrhagic Stroke. Utilizing the Point-Biserial Correlation Coefficient to analyze possible association between the Ct value and the occurrence of stroke, a 0.22 correlation coefficient implied a weak positive correlation between the Ct value and CVD occurrence.

The relationship between the cycle threshold (Ct) value and the occurrence of CVD exists weakly, and factors that might affect this relationship must be addressed and resolved. Interpreting Ct value results also requires clinical context; hence, careful utilization of such data must always be observed. Several factors, including old age, male gender, co existing comorbidities such as hypertension and diabetes mellitus, lack of maintenance medication and noncompliance, vaccination status, smoking, and alcohol intake history, contributed to the poorer outcome of the patients and the high probability of having a stroke.

BACKGROUND

COVID-19 has significantly impacted global mortality, particularly among those aged 45–84 years. Worldwide deaths exceeded official reports, reaching at least 3 million in 2020. In the Philippines, mortality increased in 2021 but declined by 2022. Key factors include comorbidities like diabetes and hypertension. Limited research, resources, and healthcare challenges hinder localized mortality prediction and management efforts.

This study analyzed 234 randomly selected COVID-19 patients admitted between April 1, 2020 and April 1, 2021, using quantitative methods, descriptive and predictive designs, and advanced statistical techniques.

Most COVID-19 patients in our study were older adults, predominantly female, with non-severe cases and mild PaO2/FiO2 ratios, indicating mild respiratory distress. Comorbidities were uncommon, but when present included hypertension and diabetes, affecting hospitalization length. Patients generally had low Sequential Organ Failure Assessment (SOFA) scores and were linked to better outcomes. Most recovered and were discharged, with a mortality rate lower in the Philippines compared to global figures. Severe cases were more common in older adults and males, often requiring mechanical ventilation. SOFA scores and PaO2/FiO2 ratios correlated with severity, while comorbidities prolonged hospital stays. Hospitalization averaged 11.3 days, shorter than global durations.

COVID-19 patients with two or more accompanying diseases are likely to stay longer in the hospital. On the other hand, patients on mechanical ventilation support are likely to have shorter hospital stay.

BACKGROUND

The COVID-19 pandemic brought insurmountable changes, leading to work demands and resource limitations that placed additional physical and occupational stress.

This study aimed to determine the change in the occurrence and intensity of musculoskeletal discomfort among selected university faculty members. It also determined the association of sociodemographic and anthropometric factors, workplace conditions, and involvement in physical activity with musculoskeletal pain.

This is an analytical cross-sectional study conducted from June 2022 to May 2023 that surveyed university faculty members from Metro Manila and Metro Cebu. Outcome measures include sociodemographic data, anthropometric measures of weight, height, body mass index, workplace conditions, exercise participation, and musculoskeletal discomfort using the Cornell Musculoskeletal Discomfort Questionnaire.

Data from 120 participants, mostly female, with an average BMI of 27.78 ± 12.09 kg/m2 and 11.82 ± 10.39 years of teaching experience revealed increased computer usage and reduced teaching hours during the Pandemic lockdown. There was also prevalent musculoskeletal discomfort (MSD), particularly in the neck, shoulder, and upper back. Factors associated with increased MSD were female gender, longer computer use, and pre pandemic MSD history.

This study underscores the significance of addressing ergonomic factors and work conditions to mitigate MSD risks among educators during challenging situations.

INTRODUCTION

Patients with diabetes are at higher risk of developing severe COVID-19 infection with a two-fold increased risk of mortality. This study described the risk factors affecting clinical outcomes of confirmed COVID-19 patients with diabetes mellitus at the University of Santo Tomas Hospital, Manila, Philippines.

This retrospective study included 204 patients with COVID-19 (34 with known type 2 diabetes and 2 with new-onset diabetes) from March to October 2020. Clinical characteristics and laboratory parameters were collected and analyzed in subjects with diabetes. A univariate logistic regression was used to calculate the odds ratios and 95% confidence interval (CI) for the patient’s risk factors associated with mortality or poor prognosis.

Moderate COVID-19 infection occurred in 52.8% of type 2 diabetes mellitus (T2DM) patients and critical COVID-19 infection in 27.8%. All patients with critical COVID-19 infection presented with acute respiratory distress syndrome, half had concomitant septic shock and respiratory failure was observed in 27.8%. The average length of hospital stay was approximately 17.5 days. T2DM patients with established atherosclerotic cardiovascular disease (ASCVD) are 5.1 times (95% CI 1.2 to 21.4) more likely to develop severe or critical COVID-19 infection, and more likely to stay in the hospital for more than 14 days. HbA1c >8.5% is a potential risk (OR = 3.7, 0.6 to 21.6) for severe to critical disease. T2DM patients with concomitant coronary artery disease are 7.6 times (95% CI 1.3 to 43.4) more likely to stay longer (more than 14 days) as compared to those without existing coronary artery disease. Prior statin use was a significant risk factor for ICU admission (p-value 0.0341). Other potential risk factors affecting clinical outcomes are obesity (OR 3, 0.4 to 22.7), prior use of thiazolidinedione (OR 7.8, 0.5 to 126.7) or sodium-glucose transporter 2 (SGLT2) inhibitors (OR 7.5, 0.4 to 145) and prior use of anti-thrombotic (OR 4.6, 0.4 to 56.8). The recovery rate of T2DM patients hospitalized for COVID-19 infection was 86.1%.

Patients with T2DM are more vulnerable to COVID-19 infection. The presence of established ASCVD increases the likelihood of severe COVID-19 disease as well as longer length of hospital stay for more than 14 days. Early recognition and prompt treatment led to a favorable recovery rate.

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.

BACKGROUND AND OBJECTIVE

COVID-19 has been associated with cardiac injury, often detectable through electrocardiographic (ECG) changes. This study seeks to characterize the cardiovascular and electrocardiographic profiles of adult patients diagnosed with COVID-19.

This study included adult patients with confirmed COVID-19 from June 2021 to June 2022. Clinical profiles and 12-lead ECG tracings were obtained from electronic medical records and reviewed independently by three cardiologists. Descriptive analysis was performed to summarize the cardiovascular and electrocardiographic findings in this population.

The study included 998 COVID-19 patients (mean age: 50 years; 53.7% male). The most common comorbidities were hypertension, diabetes, and dyslipidemia. A majority (31.36%) presented with severe COVID-19 infection. The most frequent significant ECG abnormalities observed at admission were sinus tachycardia (22.8%), and atrial fibrillation (11.02%). Additional ischemic findings included ST segment depression (2.91%), T-wave inversion (1.70%), and ST segment elevation (2.71%).

The baseline ECG findings among COVID-19 patients were predominantly normal; however, significant abnormalities were also identified. The most frequent abnormalities included sinus tachycardia, atrial fibrillation, and ischemic changes, all of which may have clinical implications.

OBJECTIVE

This study aimed to determine the psychological impact of the COVID-19 pandemic on university students, categorically focusing on effective coping strategies adopted.

The researcher used a descriptive cross-sectional design and a pseudo-random number sampling method with an inversion technique to randomly select 548 health science students who participated fully out of the sum of 4,140 students from each department. The initial goal was to include 572 students in the sample. This ensured a fair representation of students from the University of Nigeria, Nsukka (UNN). The researcher evaluated these students using the COVID-19 Student Stress Questionnaire and Brief-Cope Scales.

Findings showed that 58.8% of the respondents were females, 34.7% were enrolled in the nursing program, and 59.7% chose to live with their parents. Most of the students experienced moderate stress, with 45.25% and 5.47% experiencing extremely stressful or distressing situations, in terms of relationships and academic life, respectively. There were no significant differences in fear of contagion, regardless of the students' gender. and social isolation between students who lived with and without their parents. In terms of relationships and academic life among the students, there was no significant difference in relation to the demographic characteristics. Results also showed that 26.6% of the students used problem-focused coping “a little bit," and there was no significant difference as to their developmental characteristics for those using problem-focused coping, emotion-focused coping, or avoidant coping. However, the results indicated a greater tendency towards avoidant coping strategies, with no significant differences observed. Students disproportionately adopted problem-focused, emotion-focused, and avoidant coping strategies. Students reported a weakly significant positive correlation between emotionfocused coping and problem-focused coping, and a large negative association between fear of contagion and problem-focused coping strategies. They also reported a slightly positive correlation between relationships, academic life, and social isolation.

The study revealed that most students experience moderate stress, which gradually escalates into extremely stressful situations, particularly in relationships and academics. The researcher found no significant differences in fear of contagion or social isolation. However, avoidant coping was more prevalent compared to problem-focused and emotion-focused strategies. There were weak positive correlations between emotion-focused and problem-focused coping. Policy reform in the health and academic systems will strategically improve students' mental health.
