METHODOLOGY/PRINCIPAL FINDINGS: A total of 439 records of P. knowlesi infections in humans, macaque reservoir and vector species were collated. To predict spatial variation in disease risk, a model was fitted using records from countries where the infection data coverage is high. Predictions were then made throughout Southeast Asia, including regions where infection data are sparse. The resulting map predicts areas of high risk for P. knowlesi infection in a number of countries that are forecast to be malaria-free by 2025 (Malaysia, Cambodia, Thailand and Vietnam) as well as countries projected to be eliminating malaria (Myanmar, Laos, Indonesia and the Philippines).
CONCLUSIONS/SIGNIFICANCE: We have produced the first map of P. knowlesi malaria risk, at a fine-scale resolution, to identify priority areas for surveillance based on regions with sparse data and high estimated risk. Our map provides an initial evidence base to better understand the spatial distribution of this disease and its potential wider contribution to malaria incidence. Considering malaria elimination goals, areas for prioritised surveillance are identified.
OBJECTIVES: This study examined past month patterns of substances use and its gender difference among adolescents.
METHODS: Cross-sectional samples among adolescents aged 13-16 years who completed the Global School-based Student Health Survey (GSHS) from eight ASEAN countries were included in the analysis (n = 40,212).
RESULTS: Prevalence of past month any tobacco use was relatively high in Brunei, Indonesia, Malaysia, Thailand, and the Philippines (11-15%), but prevalence of dual cigarette and other forms of tobacco use was about 2-5% in the five countries. Past month alcohol consumption prevalence was also high in Thailand, Viet Nam, and the Philippines (16-24%), compared to the rest countries (1.4-8.2%). Moreover, prevalence of the concurrent alcohol and tobacco use was higher in Thailand and the Philippines (7 and 10%, respectively), particularly in boys (13 and 15%, respectively). Conclusions/importance: Almost 30-40% of the boys and 10-20% of girls in Malaysia, Philippines, Thailand, and Viet Nam are engaged in at least one of the two risk behaviors, and the concurrent alcohol and tobacco use was also relatively high among boys in those countries (5-15%). This study may provide some valuable insights on alcohol and tobacco policy in the region and requires to begin prevention and treatment programs in ASEAN member states.
Methods: A combination of active and passive detection of infection was carried out among communities in Batubara, Langkat, and South Nias regencies. Finger-prick blood samples from consenting individuals of all ages provided blood films for microscopic examination and blood spots on filter paper. Plasmodium species were identified using nested polymerase chain reaction (PCR) of ribosomal RNA genes and a novel assay that amplifies a conserved sequence specific for the sicavar gene family of Plasmodium knowlesi.
Results: Of 3731 participants, 614 (16.5%) were positive for malaria parasites by microscopy. PCR detected parasite DNA in samples from 1169 individuals (31.3%). In total, 377 participants (11.8%) harbored P. knowlesi. Also present were Plasmodium vivax (14.3%), Plasmodium falciparum (10.5%) and Plasmodium malariae (3.4%).
Conclusions: Amplification of sicavar is a specific and sensitive test for the presence of P. knowlesi DNA in humans. Subpatent and asymptomatic multispecies parasitemia is relatively common in North Sumatera, so PCR-based surveillance is required to support control and elimination activities.
AIM: To compare the skin diseases prompting biopsy before and during the COVID-19 pandemic.
MATERIALS AND METHODS: A retrospective study of skin diseases was performed; the skin problems were then grouped into major histopathological reactions.
RESULTS: A total of 229 biopsies were performed before the COVID-19 outbreak, whereas only 160 biopsies were done during the pandemic. Before versus during the outbreak, the proportion of major reactions were granulomatous 20.52% vs 21.88%, neoplasms 17.47% vs 20%, psoriasiform 14.85% vs 10%, vesiculobullous 9.61% vs 8.75%, others 10.92% vs 7.50%, interface dermatitis 6.99% vs 10%, vasculopathy 6.99% vs 5.63%, spongiotic 6.55% vs 8.13%, panniculitis 3.49% vs 3.75%, and superficial and deep dermal infiltrate 2.62% vs 4.38%.
CONCLUSION: A decreased total number of patients prompting less biopsies were reported during the COVID-19 outbreak. However, the three largest percentages of major histopathological reactions were still similar, namely granulomatous, neoplasms, and psoriasiform.
OBJECTIVE: To investigate the association between severe anxiety disorder and other factors with COVID-19 disease severity.
METHODS: This was cross-sectional study during March - November 2020. The diagnosis of SARS-CoV-2 was done by using RT-PCR from throat swabs, based on WHO's interim guidelines. AD was measured using self-reporting Generalized Anxiety Disorder-7 (GAD-7). All participants underwent, history taking, physical examinations, blood routine examination and chest radiography. Association between severe AD and other factors with COVID-19 disease severity were analyzed. Chi-square test (bivariate) and Logistic regression (multivariate) with the precision value of 95% was done and p-value less than 5% was considered significant.
RESULTS: Positive rate of Covid-19 patients was 43% (292 / 678). Among those 292 with Covid-19, 74 (25.3%) participants had severe disease. Multivariate analysis showed severe anxiety (OR 696.11; 95%CI: 78.54 to 6169.98; p<0.001), hypertension (OR 37.02; 95%CI: 4.49 to 305.39; p=0.001) and neutrophyl lymphocyte ratio (NLR) less than 2.89 (OR 0.15; 95%CI: 0.04 to 0.62; p=0.009).
CONCLUSION: Severe anxiety, hypertension and NLR less than 2.89 are potential independent risk factors for severe infection of SARS-CoV-2 (COVID-19).
MATERIALS AND METHODS: A total of 400 respondents were recruited, from all over the province in Indonesia. Instruments utilized were structured questionnaires including a demographic questionnaire, work performance scale (WPS), daily work stress scale. The design used was cross-sectional with a nonprobability sampling method and the data analysis with Chi-Square. The respondents were 400 respondents.
RESULTS: Shows that both respondents who had high, moderate, and low-stress levels on work from home (p>0.001), work from office (p>0.001), and Hybrid (p>0.001). Respondents also had good work performance with all varied work methods.
CONCLUSIONS: Based on this research, each worker has more varied work stress, even though they still carry out their jobs well, and have good performance.
