BackgroundCyclones and storm surges threaten coastal communities worldwide.The World Meteorological Organization defines a tropical cyclone as "a non-frontal synoptic scale originating over or subtropical waters with organized convection definite cyclonic surface wind circulation". 1ore specifically, in the south-east Indian Ocean is when sustained speed more than 33 nautical miles per hour (> 62 km/h).The surge represents major cause of death injury during cyclone.A difference between water...
The total number of influenza cases with medical attendance has been estimated from sentinel surveillance data in Japan under a random sampling assumption institutions among the institutions. 2009 pandemic offered research opportunity to validate sentinel-based estimation method using proportion infections measured by population-wide seroepidemiological survey employing hemagglutinin inhibition (HI) assay. For entire population, we age-standardized at 28.5% and 23.5% cut-off values HI titer...
Background Malaria is a major public health problem in Bangladesh, frequently occurring as epidemics since the 1990s. Many factors affect increases malaria cases, including changes land use, drug resistance, control programs, socioeconomic issues, and climatic factors. No study has examined relationship between Bangladesh. Here, we investigate parameters [rainfall, temperature, humidity, sea surface temperature (SST), El Niño-Southern Oscillation (ENSO), normalized difference vegetation...
While floods can potentially increase the transmission of dengue, only few studies have reported association dengue epidemics with flooding. We estimated effects river levels and rainfall on hospital admissions for fever at 11 major hospitals in Dhaka, Bangladesh. examined time-series number relation to from 2005 2009 using generalized linear Poisson regression models adjusting seasonal, between-year variation, public holidays temperature. There was strong evidence an high levels....
Malaria treatment-seeking practices vary worldwide and Bangladesh is no exception. Individuals from 88 villages in Rajasthali were asked about their practices. A portion of these households preferred malaria treatment the National Control Programme, but still a large number continued to use drug vendors approximately one fourth individuals surveyed relied exclusively on non-control programme treatments. The risks low-control usage include incomplete treatment, possible misuse anti-malarial...
Both depression and tuberculosis (TB) are global public health problems that have a substantial impact on human health. However, depressive state among TB patients has not been well investigated in the Philippines.To assess pulmonary (PTB) to identify factors associated with Manila, Philippines.A cross-sectional survey of PTB was conducted at 10 centres two non-government organisation clinics providing directly observed treatment District I, Tondo, Manila. Face-to-face interviews 561 using...
Coronavirus disease 2019 (COVID-19) was extraordinarily harmful, with high rates of infection and hospitalization. This study aimed to evaluate the impact COVID-19 vaccination status other factors on hospitalization severity, using data from Nagasaki Prefecture, Japan. Confirmed cases were included differences in characteristics between different statuses, or not, patients varying levels severity analyzed. Furthermore, logistic regression used calculate odds ratio (ORs) 95% confidence...
Multiple micronutrient deficiencies, in particular iron deficiency anaemia (IDA) is a severe public health problem Lao People's Democratic Republic (Lao PDR). Because of the practical difficulties encountered improving nutritional adequacy traditional complementary foods and limitations associated with use liquid supplementation for treatment prevention IDA infants young children, recently, home-fortification multivitamins minerals sprinkles was recommended. This study aims to compare effect...
Background Malaria is a major public health concern in Bangladesh and it highly endemic the Chittagong Hill Tracts where prevalence was 11.7% 2007. One sub-district, Rajasthali, had of 36%. Several interventions were introduced early 2007 to control malaria. This study undertaken evaluate impacts these intensive stage on malaria Bangladesh. assesses whether or not high remains, if so, which areas individuals remain at risk infection. Methods Principal Findings A 2-stage cluster sampling...
Abstract It has been hypothesized that nitrogen fixation occurs in the human gut. However, whether gut microbiota truly this potential remains unclear. We investigated nitrogen-fixing activity and diversity of nitrogenase reductase (NifH) genes faecal humans, focusing on Papua New Guinean Japanese individuals with low to high habitual intake. A 15 N 2 incorporation assay showed significant enrichment all samples, irrespective host intake, which was also supported by an acetylene reduction...
BackgroundIt has been reported that the El Niño–Southern Oscillation (ENSO) influences interannual variation of endemic cholera in Bangladesh. There is increased interest influence Indian Ocean dipole (IOD), a climate mode coupled ocean–atmosphere variability, on regional ocean Bay Bengal and monsoon rainfall.ObjectivesWe explored relationship between IOD number patients Bangladesh, controlling for effects ENSO.MethodsTime-series regression was performed. Negative binomial models were used...
Dengue infection is endemic in many regions throughout the world. While insecticide fogging targeting vector mosquito Aedes aegypti a major control measure against dengue epidemics, impact of this method remains controversial. A previous mathematical simulation study indicated that minimized cases when conducted soon after peak disease prevalence, although was minimal, possibly because seasonality and population immunity were not considered. Periodic outbreak patterns are also highly...
Coughing plays an important role in influenza transmission; however, there is insufficient information regarding the viral load cough because of lack convenient and reliable collection methods. We developed a portable airborne particle-collection system to measure load; it equipped with air sampler draw pass through gelatin membrane filter connected cone-shaped, megaphone-like device guide airflow membrane. The was dissolved medium, measured using quantitative real-time reverse...
Abstract Background Malaria remains a major public health concern in the Democratic Republic of Congo (DRC), and school-age children are relatively neglected malaria prevalence surveys may constitute significant reservoir transmission. This study aimed to understand burden infections Kinshasa/DRC. Methods A total 634 (427 asymptomatic 207 symptomatic) blood samples collected from aged 6 14 years were analysed by microscopy, RDT Nested-PCR. Results The overall Plasmodium spp. PCR was 33%, 42%...
In Tsarang (at 3560 m), which is located in Mustang, 62.7% of the residents answered that they had a subjective medical history arthritis, and 41.1% their families arthritis on survey conducted 2017. The expression hypoxia-inducible factor (HIF) its effects are deeply involved hypoxic adaptation Tibetan highlanders. At same time, HIF also related to onset rheumatoid arthritis. Therefore, adaptive mechanism acquired by highlanders may promote development prevalence estimated be approximately...
Malaria is a major public health burden in Southeastern Bangladesh, particularly the Chittagong Hill Tracts region. endemic 13 districts of Bangladesh and highest prevalence occurs Khagrachari (15.47%). A risk map was developed geographic factors identified using Bayesian approach. The geostatistical model from previously individual environmental covariates (p < 0.2; age, different forest types, elevation economic status) for malaria WinBUGS 1.4. Spatial correlation estimated within...
Abstract In many countries with low to moderate tuberculosis (TB) incidence, cases have shifted elderly persons. It is unclear, however, whether these are associated recent Mycobacterium transmission or represent reactivation of past disease. During 2009–2015, we performed a population-based TB investigation in Yamagata Prefecture, Japan, using in-depth contact tracing and 24-loci variable-number tandem-repeat typing optimized for Beijing family M. strains. We analyzed 494 strains, which 387...
Abstract Background Understanding Plasmodium falciparum population diversity and transmission dynamics provides information on the intensity of malaria transmission, which is needed for assessing control interventions. This study aimed to determine P. allelic multiplicity infection (MOI) among asymptomatic symptomatic school-age children in Kinshasa Province, Democratic Republic Congo (DRC). Methods A total 438 DNA samples (248 190 symptomatic) were characterized by nested PCR genotyping...
