INTRODUCTION: Our aim was to study the prevalence of frailty and its associated factors in a subacute geriatric ward. METHODS: This was a cross-sectional study of 167 participants between June 2018 and June 2019. Baseline demographics and participants' Mini Nutritional Assessment, Geriatric Depression Scale, Mini Mental State Examination, Charlson's Comorbidity Index and LACE index scores were obtained. Functional measurements such as modified Barthel's Index scores and hand grip strength (HGS) were taken. Frailty was assessed using the Clinical Frailty Scale (CFS) and the FRAIL scale. Data on history of healthcare utilisation, medications, length of stay, selected blood investigations and presence of geriatric syndromes were also collected. RESULTS: The prevalence of pre-frailty (CFS 4) and frailty (CFS ≥ 5) was 16.2% and 63.4%, respectively. There were significant associations between CFS and age (pre-frail vs. non-frail: odds ratio [OR] 1.14, 95% confidence interval [CI] 1.04-1.25, P = 0.006; frail vs. non-frail: OR 1.08, 95% CI 1.01-1.15, P = 0.021), HGS at discharge (frail vs. non-frail: OR 0.90, 95% CI 0.82-0.99, P = 0.025), serum albumin (frail vs. non-frail: OR 0.90, 95% CI 0.82-0.99, P = 0.035) and the presence of urinary incontinence (frail vs. non-frail: OR 3.03, 95% CI 1.19-7.77, P = 0.021). CONCLUSION Frailty is highly prevalent in the subacute geriatric setting and has many associated factors. In this study, independent factors associated with frailty were age, HGS at discharge, serum albumin and urinary incontinence. This has implications for future resource allocation for frail older inpatients and may help direct further research to study the effectiveness of frailty-targeted interventions.

This work investigates the Musa Paradisiaca plant and its tepal extracts. The research findings show that the tepal extracts of M. Paradisiaca contain high phytochemical activity. Hence we can conclude that these plants have a number of beneficial properties. Phytochemical analysis concludes that the plant is rich in flavonoids, phenolic compounds, tannins, terpenoids, and phytosterol. In the current work, silver nanoparticles (AgNPs) have revealed the antioxidant properties of M. Paradisiaca. The results show that the methanolic extracts of these tepals exhibit antioxidant potential and are also sources of natural antioxidant compounds, though comparatively, AgNPs have shown the best antioxidant activity. This work investigates the link between the ethnopharmacological statements and the bioactive constituents found in M. Paradisiaca toward all probable markers for cervical cancer via in vivo studies and molecular docking, to form a pharmacophore setting for the active target. However, most of the mechanisms of action of herbal medicines are not in total agreement, and the information collected from their traditional remedies over the years must not be neglected. Hence, it is sensible to investigate the options available in herbal medicine for cancer progression. Biosynthesised AgNPs are principally spherical and nanosized. It was also found that tepalmediated AgNPs exhibit excellent antimicrobial efficacy against tested human pathogens. This green method can be used as a better alternative source than the chemical fabrication of nanomaterials and the biosynthesised nanoparticles can be used in antibacterial medicines. The methanolictepal extract of M. Paradisiaca with AgNPs displayed proficient antidiabetic properties in the diabetes rat model and so could have a possible development for medical use in the future

ary phytochemical screening. The resultsshowed that the ethanolic crude extract of the leaf containhigh phytochemical activity hence B.oleraceavaracephalais rich in flavonoids, phenolic compounds, carbohydratesand phytosterols. Materials and methods: The ethanolic extract was used tosynthesise copper nanoparticles. The copper nanoparticleswere successfully synthesised from copper sulphatesolution which was identified by the colour change fromdark green colour of the extract. Thus the B.oleracea varacephala is a good source to synthesis coppernanoparticles. The synthesised copper nanoparticles werecharacterised using Scanning Electron Microscope (SEM)analysis. The SEM image displayed the high-densitynanoparticles synthesised by leaf extracts and that thenanoparticles were crystals in shape. Results: The copper nanoparticles (CNP) bind to the leafextract. B.oleraceavaracephalaalso has shown theantimicrobial and antioxidant activity. A comparative studywas done between ethanolic its crude extract andnanoparticles. Both extracts exhibited zone of inhibition andbetter antioxidant potential but the CuNPs shows majorzone of inhibition and showed more antioxidant activity.Anticancer activity of B.oleraceavaracephalaagainstCervical HeLa cell line was confirmed using ethanolic crudeextract and CNP. The results showed that HeLa cellsproliferation was inhibited with increasing concentration ofethanolic crude extract and copper nanoparticles. From theresults, it was seen that percentage viability of the cancercells decreased with increased concentration of the sampleswhereas cytotoxicity against HeLa cell lines increased withthe increased concentration of the samples. Conclusion: Thus B.oleraceavaracephalapossessesanticancer activity against HeLa cell lines.

BACKGROUND: More than 140 million people drink arsenic-contaminated groundwater. It is unknown how much arsenic exposure is necessary to cause neurological impairment. Here, we evaluate the relationship between neurological impairments and the arsenic concentration in drinking water (ACDW). PARTICIPANTS AND METHODS: A cross-sectional study design was employed. We performed medical examinations of 1867 residents in seven villages in the Thabaung township in Myanmar. Medical examinations consisted of interviews regarding subjective neurological symptoms and objective neurological examinations of sensory disturbances. For subjective neurological symptoms, we ascertained the presence or absence of defects in smell, vision, taste, and hearing; the feeling of weakness; and chronic numbness or pain. For objective sensory disturbances, we examined defects in pain sensation, vibration sensation, and two-point discrimination. We analyzed the relationship between the subjective symptoms, objective sensory disturbances, and ACDW. RESULTS: Residents with ACDW ≥ 10 parts per billion (ppb) had experienced a "feeling of weakness" and "chronic numbness or pain" significantly more often than those with ACDW < 10 ppb. Residents with ACDW ≥ 50 ppb had three types of sensory disturbances significantly more often than those with ACDW < 50 ppb. In children, there was no significant association between symptoms or signs and ACDW. CONCLUSION Subjective symptoms, probably due to peripheral neuropathy, occurred at very low ACDW (around 10 ppb). Objective peripheral nerve disturbances of both small and large fibers occurred at low ACDW (> 50 ppb). These data suggest a threshold for the occurrence of peripheral neuropathy due to arsenic exposure, and indicate that the arsenic concentration in drinking water should be less than 10 ppb to ensure human health.

Malaria, tuberculosis, and hepatitis are common and notorious infectious diseases in Myanmar. Despite intensive efforts to control these diseases, their prevalence remains high. For malaria, which is a vector-borne disease, a remarkable success in the reduction of new cases has been achieved. However, the annual number of tuberculosis cases has increased over the last few decades, and the prevalence of chronic viral hepatitis infection has been high in Myanmar and other nearby countries. Early detection and prompt treatment are crucial to control these diseases. We have devoted our research efforts to understanding the status of these infectious diseases and working towards their eventual elimination for the last four years with the support of the Korea International Cooperation Agency. In the modern era, an infection that develops in one geographical area can spread globally because national borders do not effectively limit disease transmission. Our efforts to understand the status of infectious diseases in Myanmar will benefit not only Myanmar but also neighboring countries such as Korea.

Objectives: To determine the distribution of Plasmodium (P) species including Plas-modium knowlesi and to compare the specificity and sensitivity of microscopy with nested PCR in malaria diagnosis. Methods: The study was conducted in Kawthaung, southern Myanmar. Ninety clinically suspected malaria patients were screened for malaria by Giemsa stained microscopy and confirmed by nested PCR. Results: Among the participants, 57 (63.3％) were positive and 33 (36.7％) were negative by microscopy. Of positive samples, 39 (68.4％) were Plasmodium falciparum, 17 (29.8％) Plasmodium vivax and 1 (1.8％) Plasmodium malariae, whereas 59-amplified by PCR were 40 (67.8％), 18 (30.5％) and 1 (1.7％) respectively. PCR amplified 2 mi-croscopy negative samples. Two samples of P. falciparum detected by microscopy were amplified as P. vivax and vice versa. All samples were negative for Plasmodium ovale, P. knowlesi and mixed infections. Microscopy had a very good measure of agreement (k= 0.95) compared to nested PCR. Sensitivity and specificity of microscopy for diag-nosis of P. falciparum were 92.5％(95％CI:79.6–98.4) and 96.0％(95％CI:86.3–99.5) respectively, whereas for P. vivax were 83.3％(95％CI:58.6–96.4) and 97.2％(95％CI:90.3–99.7). Conclusions: P. knowlesi was not detected by both microscopy and PCR. Giemsa stained microscopy can still be applied as primary method for malaria diagnosis and is considered as gold standard. As to the lower sensitivity of microscopy for vivax malaria, those with previous history of malaria and relapse cases should be diagnosed by RDT or PCR combined with microscopy. Inaccuracy of species diagnosis highlighted the requirement of training and refresher courses for microscopists.

In the era of (pre) elimination setting, the prevalence of malaria has been decreasing in most of the previously endemic areas. Therefore, effective cost- and time-saving validated pooling strategy is needed for detection of malaria in low transmission settings. In this study, optimal pooling numbers and lowest detection limit were assessed using known density samples prepared systematically, followed by genomic DNA extraction and nested PCR. Pooling strategy that composed of 10 samples in 1 pool, 20 µl in 1 sample, was optimal, and the parasite density as low as 2 p/µl for both falciparum and vivax infection was enough for detection of malaria. This pooling method showed effectiveness for handling of a huge number of samples in low transmission settings (<9% positive rate). The results indicated that pooling of the blood samples before DNA extraction followed by usual nested PCR is useful and effective for detection of malaria in screening of hidden cases in low-transmission settings.

The lower percentage of water, sanitation and hygiene are the root causes of diarrhoea and cholera. Cholera is a sudden onset of acute watery diarrhoea which can progress to severe dehydration and death if untreated. The current pandemic, Vibrio Cholera O1 started in 1961. This study explores water, sanitation, hygiene and cholera and diarrhoea in three affected villages of Beluran District, Sabah Malaysia to support effective and timely public health intervention. This cross sectional study uses purposive sampling. All (114) households were interviewed and household water samples collected. The study reported lower coverage improved sanitation facilities (35.3% to 52.3%), no latrine at home (37% to 63%), improved water supply (52% to 60%), and prevalence of hand washing after toilet (57% - 74%). For water quality, Ecoli was present in household water (32% to 37%) but Vibrio cholerae was not isolated in any of the water samples tested. Statistically significant associations were found for; 1) occupation−non-agriculture and unimproved sanitation facility and 2) house ownership and correct knowledge of ORS preparation. Predictors for household water quality were: latrine at home, and improved household toilet. Aggressive strategies to improve water supply, sanitation and hygiene−hand washing after toilet−were recommended for future prevention of cholera and diarrhoea in the affected area.

Island health differs from other health care systems, particularly in that there are limited resources and referral faculties available. With globalisation and climate change, island populations have become increasingly vulnerable to natural disasters and global pandemics. This study will identify, explore, compare and report on island health issues facing in the western Pacific, before making appropriate recommendations. A review of selected health indicators in Pacific islands was collected from the World Health Organization (WHO) and other publicly available resources. In the Pacific region, 15 islands saw lower health expenditure (
