The Lancet regional health. Southeast Asia 31 100510-100510 2024年12月 査読有りBACKGROUND: Cholera cases have increased globally across the Eastern Mediterranean, Africa, Southeast Asia, and parts of Europe since early 2024. This study aims to identify cholera hotspots and understand the spatial distribution of cholera in Kolkata and surrounding regions, a key cholera reservoir. Additionally, we examine sociodemographic factors and aspects related to water, sanitation, and hygiene (WASH). METHODS: Cholera clusters were detected using kernel density estimation and spatial autocorrelation through Global Moran's-I statistics, with local cluster patterns examined using Local Moran's-I statistics. Cholera cases from August 2021 to December 2023, treated at two tertiary care facilities in Kolkata: Infectious Diseases and Beleghata General Hospital and Dr. B C Roy Post Graduate Institute of Paediatric Sciences Hospital were included. Additionally, through a case-control study, 196 culture-confirmed cholera cases and 764 age/sex-matched neighborhood controls were enrolled, to investigate cholera risk factors. FINDINGS: Spatial analysis revealed a concentration of 196 cholera cases in Kolkata and its surrounding regions of Howrah, Hooghly, and North and South 24 Parganas. Hotspot analysis showed significant clustering in several Kolkata wards (31, 33, 56, 46, 57, 58, 59, 61, 66, 71, and 107), particularly in the northern, central, and east Kolkata wetlands areas (Global Moran's I statistic = 0.14, p < 0.001). These clusters had proximity between cases, with a median distance of 187.7 m, and 25.5% of cases as close as 73.9 m apart, suggesting localized transmission. Hotspots were identified with an average distance of 1600 m between them. Local Moran's I analysis found dense "high-high" clusters in these areas (p < 0.01), with a mean Moran's I index of 0.3, (range 0.1-4.6). The case-control study revealed that males were more likely to contract cholera, with an adjusted odds ratio of 2.4 (p < 0.01). There was no significant association found between cholera infection and sociodemographic factors or various WASH practices. INTERPRETATION: The findings emphasize the importance of targeted interventions, especially in identified hotspots, to mitigate cholera transmission. Addressing Socio-economic, and environmental factors especially improvement in WASH practices may further enhance prevention effects.

Journal of International Nursing Research advpub 2023年Objective: The reason behind the constant denial to accept any kind of behavioral changes among non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) patients even after counseling and why behaviors that lead to disease progression are maintained is unclear. This study aimed to describe the daily living behaviors of NAFLD/NASH patients and elucidate the reasons behind their inability to change their routines, which are problematic as they lead to disease progression. Methods: A qualitative study was conducted using an ethnographic design. The data collection methods included participatory observation, field note-taking, and semistructured interviewing of eight NAFLD patients in their daily lives at their homes and workplaces. SpradleyJINRJJ-15s Developmental Research Sequence method was employed to analyze the data. This paper conforms to the standards for reporting qualitative research. Results: Four themes were generated: (1) health beliefs built in the family, (2) difficulty in systematizing health knowledge, (3) dependence on food, and (4) social disadvantages. Conclusions: NAFLD patients had negative influences from the family environment from childhood, lacked integrated knowledge about the risk factors, and developed food addiction. Furthermore, social disadvantages, such as a stressful environment, an environment where there was less chance to have significant others to support their treatment, financial difficulties, and lower educational background, influenced all factors.

JMA journal 3(3) 216-231 2020年7月15日Introduction: Recent estimates suggest that there is a substantial number of Japanese students with developmental disabilities. This study aimed to examine potential associations between autistic, autistic subcomponents, and attention deficit/hyperactivity disorder (ADHD) traits with student performance (as measured by presenteeism) and class attendance among Japanese university students. Methods: Participants comprised 721 students from different regions of Japan who completed a self-administered internet survey. Autistic and ADHD traits were measured using an abridged version of the autism spectrum quotient (AQ-Short) and adult ADHD self-report scale (ASRS). Presenteeism, which is an indicator of student performance, was assessed using the modified World Health Organization Health and Work Performance Questionnaire. Class attendance during the past year was self-reported by participants. Results: Students with high levels of autistic traits and high levels of ADHD traits were significantly more likely to report poor student performance (odds ratio [OR] = 3.07, 95% confidence interval [95% CI]: 1.90-4.96; and OR = 2.13, 95% CI: 1.32-3.42, respectively). Regarding autistic trait subcomponents, students with high levels of preference for routine (OR = 2.39, 95% CI: 1.38-4.13) and high levels of difficulties with social skills (OR = 1.81, 95% CI: 1.03-3.18) were also significantly more likely to report poor student performance. There were borderline significant associations between traits of attention-switching difficulties and poor student performance (OR = 1.78, 95% CI: 1.00-3.15). Regarding ADHD trait subcomponents, students with high levels of inattention (OR = 2.88, 95% CI: 1.32-6.26) were also significantly more likely to report poor student performance. Students with both high levels of autistic traits and high levels of ADHD traits were more likely to report poor student performance than those with high levels of only one trait type. There were, however, no statistically significant associations between these traits and low class attendance risk. Conclusions: Sickness presenteeism was significantly associated with high levels of both autistic traits and ADHD traits among Japanese university students.
