Saliva has been demonstrated as feasible alternative to naso-oropharyngeal swab (NOS) for SARS-CoV-2 detection through reverse transcription quantitative/real-time polymerase chain reaction (RT-qPCR). This study compared the diagnostic agreement of conventional NOS, saliva with RNA extraction (SE) and saliva without RNA extraction (SalivaDirect) processing for RT-qPCR in identifying SARS-CoV-2. All techniques were also compared, as separate index tests, to a composite reference standard (CRS) where positive and negative results were defined as SARS-CoV-2 detection in either one or no sample, respectively. Of 517 paired samples, SARS-CoV-2 was detected in 150 (29.01%) NOS and 151 (29.21%) saliva specimens. The saliva-based tests were noted to have a sensitivity, specificity and accuracy (95% confidence interval) of 92.67% (87.26%, 96.28%), 97.55% (95.40%, 98.87%) and 96.13% (94.09%, 97.62%), respectively, for SE RT-qPCR and 91.33% (85.64%, 95.30%), 98.91% (97.23%, 99.70%) and 96.71% (94.79%, 98.07%), respectively, for SalivaDirect RT-qPCR compared to NOS RT-qPCR. Compared to CRS, all platforms demonstrated statistically similar diagnostic performance. These findings suggest that both conventional and streamlined saliva RT-qPCR are at least non-inferior to conventional NOS RT-qPCR in detecting SARS-CoV-2.

Background. The reference range of total testosterone needs to be established locally as ethnic differences in adiposity, insulin sensitivity, and sex hormone-binding globulin (SHBG) levels may affect total testosterone levels. The aim of this study is to establish the reference intervals of total testosterone from healthy, young adult Filipino males. Methods. The study included 110 healthy, Filipino male volunteers aged 21–40, studying or working at the University of the Philippines Manila. Clinical history, height, weight, body mass index (BMI), and blood pressure (BP) were obtained, and blood for total testosterone, SHBG, albumin, insulin, fasting blood sugar (FBS), and total cholesterol was collected. Free testosterone was calculated using Vermeulen’s formula. The 2.5th to 97.5th percentiles of subjects for total testosterone were used as the normative range for Filipino men. Results. The reference range of total testosterone is 7.33–53.01 nmol/L. Conclusion. The present study derived reference ranges of total testosterone using data from apparently healthy, young adult men to support clinical services.

Patients with systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) are perceived to be more vulnerable to worse COVID-19 infection outcome. Furthermore, severe shortage in hydroxychloroquine supply was experienced. We presented the psychological responses of Filipino SLE and RA patients to the COVID-19 pandemic and shortage of hydroxychloroquine supply. A total of 512 completed online surveys from SLE and RA patients were gathered from May 19 to 26, 2020. The online survey collected data on socio-demographics, health status, contact history, health service utilization, use of hydroxychloroquine, COVID-19 knowledge and concerns, precautionary measures, information needs, the validated Impact of Events Scale-Revised (IES-R) and Depression, Anxiety and Stress Scales (DASS-21) ratings. The psychological impact of COVID-19 outbreak was at least moderate in 20%. The mean IES-R score was higher among SLE (22.34, SD=14.39) than RA (18.85, SD=13.24) patients. Stress, anxiety and depression were moderate to severe in 12.3%, 38.7%, and 27.7% of respondents. The mean stress subscale score was 10.11 (SD=7.95), mean anxiety subscale score was 6.79 (SD=6.57) and mean depression subscale score was 9.03 (SD=8.77). The risk factors for adverse mental health during the COVID-19 pandemic include the presence of comorbidity of hypertension and asthma; being a healthcare worker; and presence of specific symptoms of myalgia, cough, breathing difficulty, dizziness and sore throat. The protective factors for mental health during the pandemic include satisfaction with available health information and wearing of face masks. In the third month of the pandemic in the Philippines, 20% of the respondents with lupus and RA experienced moderate to severe psychological impact. There was moderate to severe anxiety in 38.7% and moderate to severe depression in 27%. Identification of factors that affect mental health in lupus and RA is useful in implementation of effective psychological support strategies.

Background and objectives: The loss of muscle or fat free mass (FFM) as a result of systemic inflammation and poor nutrition in Chronic Obstructive Pulmonary Disease (COPD), is recognized as an important factor that influences symptoms and disease-related outcomes. To date, there are no data on body composition among Filipino COPD patients and how it impacts COPD disease severity. This paper examined the relationship of Fat Free Mass Index (FFMI = FFM/height) and sarcopenia with COPD disease severity variables. Methods: This was a cross-sectional analytic study comparing low and normal FFMI, sarcopenic and nonsarcopenic COPD patients, in terms of lung function, exercise capacity, and quality of life score. Filipino COPD patients older than 40 years were included. Patients performed six minute walking distance (6MWD), handgrip strength (HGS), and quality of life status evaluation using Filipino version of COPD Assessment Test (CAT). Body composition was measured using bioelectrical impedance analysis (BIA). Results: A total of 41 patients were included. The mean age was 69.22 years. The prevalence of being underweight and having sarcopenia was 32% and 46%, respectively. Point biserial correlation showed that COPD patients with low FFMI had a statistically significant reduction in peak inspiratory flow (r= -0.5791, P value 0.0002), peak expiratory flow (r= -0.4475, P value 0.0055), and handgrip strength (r= -0.4560, P value 0.0027); and lower CAT score (r= -0.3422, P value 0.0285). Similar findings were observed among sarcopenic COPD patients. Conclusion: The prevalence of being underweight and having sarcopenia was high. Low FFMI results in reduction of lung function and upper limb muscle strength among Filipino COPD patients. Keywords: chronic obstructive pulmonary disease, nutrition, body composition, sarcopenia, lung function

Despite the vaccine against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) being reported to be safe and effective, the unwillingness to vaccinate and doubts are still common. The aim of this international study was to assess the major reasons for the unwillingness to vaccinate in a group of students from Poland (n = 1202), Bangladesh (n = 1586), India (n = 484), Mexico (n = 234), Egypt (n = 566), Philippines (n = 2076), Pakistan (n = 506), Vietnam (n = 98) and China (n = 503). We conducted an online cross-sectional study that aimed to assess (1) the percentage of vaccinated and unvaccinated students and (2) the reasons associated with willingness/unwillingness to the vaccine. The study included 7255 respondents from 9 countries with a mean age of 21.85 ± 3.66 years. Only 22.11% (n = 1604) of students were vaccinated. However, the majority (69.25%, n = 5025) expressed a willingness to be vaccinated. More willing to vaccinate were students in informal relationships who worked mentally, used psychological/psychiatric services before the pandemic, and studied medicine. There are cultural differences regarding the reasons associated with the unwillingness to vaccinate, but some ‘universal’ might be distinguished that apply to the whole group.

The novel Coronavirus-2019 (COVID-19) was declared a pandemic by the World Health Organization (WHO) in March 2020, impacting the lifestyles, economy, physical and mental health of individuals globally. This study aimed to test the model triggered by physical symptoms resembling COVID-19 infection, in which the need for health information and perceived impact of the pandemic mediated the path sequentially, leading to adverse mental health outcomes. A cross-sectional research design with chain mediation model involving 4612 participants from participating 8 countries selected via a respondent-driven sampling strategy was used. Participants completed online questionnaires on physical symptoms, the need for health information, the Impact of Event Scale-Revised (IES-R) questionnaire and Depression, Anxiety and Stress Scale (DASS-21). The results showed that Poland and the Philippines were the two countries with the highest levels of anxiety, depression and stress; conversely, Vietnam had the lowest mean scores in these areas. Chain mediation model showed the need for health information, and the perceived impact of the pandemic were sequential mediators between physical symptoms resembling COVID-19 infection (predictor) and consequent mental health status (outcome). Excessive and contradictory health information might increase the perceived impact of the pandemic. Rapid COVID-19 testing should be implemented to minimize the psychological burden associated with physical symptoms, whilst public mental health interventions could target adverse mental outcomes associated with the pandemic.

Psoriatic arthritis is a seronegative arthropathy occurring in the presence of psoriasis. In majority of cases, typical psoriatic skin lesions precede joint disease, making diagnosis of psoriatic arthritis without typical skin lesions, a diagnostic challenge. Nail lesions are commonly seen in patients affected by this condition, making it a useful clue in the diagnosis of psoriatic arthritis. This is a case of a 58-year-old Filipino woman presenting with sudden acute urinary retention and weakness of both lower extremities accompanied with active polyarthritis. Onycholytic nail changes initially thought to be a fungal nail infection led to the diagnosis of psoriatic arthritis involving the spine. The patient was eventually treated with methotrexate and non-steroidal anti-inflammatory drugs leading to full resolution of symptoms. The patient is currently ambulatory and on regular follow-up. This case report highlights the importance of clinical and physical findings particularly the nails that would lead to a diagnosis of psoriatic arthritis.
