     概要を見る

    The delayed presentation and diagnosis of COVID-19 can contribute to spread of the disease to others but can also cause severe conditions. This study examined factors associated with delayed diagnosis among patients with COVID-19 in Okinawa, Japan. We used the data from 7125 reported cases of people living in Okinawa prefecture with symptom onset between September 2020 and March 2021. The outcome variable was the number of days from symptom onset to diagnosis. The predictor variables included age, sex, occupation, residential area, presumed infection route, and the day of the week. Cox regression analysis was used to compare the outcome between categories for each predictor variable. The median number of days from onset to diagnosis was 3 days, with an interquartile range of 1 to 5 days. Significantly more time from onset to diagnosis was observed in patients in their 60s vs. those in their 20s (hazard ratio: 0.88; 95% confidence interval: 0.81–0.96); hospitality workers were compared to office workers (0.90; 0.83–0.97), patients with unknown infection routes to those with known infection routes (0.77; 0.70–0.84), and those with symptom onset on Sundays/national holidays to those with symptom onset on weekdays (0.90; 0.85–0.96).

    Abstract Background The World Health Organization (WHO) estimated that 29% of global tuberculosis (TB) and almost 47% of childhood TB cases were not reported to national TB programs in 2019. In Cambodia, most childhood TB cases were reported from health facilities supported by the Global Fund to Fight AIDS, Tuberculosis, and Malaria in 2019. This study aimed to compare the healthcare providers' knowledge, attitude, and practices (KAP) on childhood TB case detection in operational districts (ODs) with high and low childhood TB case detection in Cambodia. Methods We conducted a cross-sectional study between November and December 2020 among healthcare providers in 10 purposively selected ODs with high childhood TB case detection and 10 ODs with low childhood TB case detection. A total of 110 healthcare providers from referral hospitals (RHs) and 220 from health centers (HCs) were interviewed. We collected information on socio-demographic characteristics, training, and KAP on childhood TB. Pearson's Chi-square or Fisher's exact and Student's t-tests were performed to explore the differences in KAP of healthcare providers from ODs with low vs. high childhood TB detection. Results Of the 330 respondents, 193 were from ODs with high childhood TB case detection, and 66.67% were from HCs. A significantly higher proportion (46.11%) of respondents from ODs with high childhood TB case detection received training on childhood TB within the past two years than those from low childhood TB case detection ODs (34.31%) (p = 0.03). Key knowledge on childhood TB was not significantly different among respondents from ODs with high and low childhood TB case detection. A significantly higher proportion of respondents from ODs with high childhood TB case detection had a good attitude (98.96 vs. 97.08%, p = 0.002) and performed good practices (58.55 vs. 45.26%, p = 0.02) on contact investigation in the community than those from low childhood TB case detection ODs. Conclusions Healthcare providers from ODs with high childhood TB detection had better attitudes and practices towards childhood TB. The attitudes and practices need to be improved among healthcare providers in ODs with low case detection. Further investment in training and experience sharing on childhood TB case detection among healthcare providers is needed to improve childhood TB case detection.

     概要を見る

    BACKGROUND: The number of out-of-school children and adolescents has been increasing globally. In sub-Saharan Africa, an estimated 23 million adolescents leave school due to poverty, teenage pregnancy, and unspecified illnesses. While the reasons for absenteeism are well-known, the factors involved in the decision to return to school have not been analyzed. This study aimed to identify the factors that promote primary school re-entry among chronic adolescent absentees in rural sub-Saharan Africa. METHODS: Qualitative data were gathered through participant observation, in-depth interviews, and focus group discussions involving nine pupils who returned to school after chronic absenteeism and 140 adult stakeholders in Mbita sub-county, Kenya. Data were analyzed using a thematic analysis method. RESULTS: The results of thematic analysis showed that the factors promoting school re-entry can be categorized into four, namely: 1) social norm: "school for a better life"; 2) linkage of community and school; 3) supportive environment; and 4) using discipline to make adolescents serious about their education. CONCLUSION: School re-entry among chronic absentees in Mbita sub-county is promoted by both community and school factors. It was observed that social norms regarded an education as a "passport to a better life." Adolescents, teachers, and community leaders view education as a means of improving one's socio-economic status. Two essential elements of health-promoting schools, a supportive environment and a linkage with community, effectively promoted returning to the school among adolescents. Introducing health-promoting schools was recommended to effectively implement a school re-entry policy in Kenya.

     概要を見る

    BACKGROUND: Although hypertension is becoming more prevalent among the adult population of the Lao People's Democratic Republic (PDR), with a prevalence of approximately 20% in 2013, treatment adherence of patients with hypertension, especially those in rural areas, remains poorly understood. The objective of the present study was to examine the rate of medication adherence to antihypertensive medicines among outpatients with hypertension in rural districts of the Savannakhet. METHODS: A prospective observational study was conducted in Xepon, Phin, and Nong districts. The study population was outpatients aged 18 years or older who were prescribed antihypertensive medicines at three district hospitals between February and August 2017. Data were collected on the first day of treatment (day 0) and the day of follow-up (around day 7) through interviews with the patients and outpatient registration books. The medication adherence rate was determined using the four-item Morisky Medication Adherence Scale. The level of adherence was evaluated by the sum of the scale, with scores ranging from 0 to 4 points. The adherent group, namely those with a score of 0, and the non-adherent group, namely those with scores of 1 to 4 points, were compared. Fisher's exact test was used to identify factors associated with medication adherence. RESULTS: Of the 68 patients examined, 38.2% newly began treatment. Half of the patients (n = 34, 50.0%, 95% CI 0.38 to 0.62) adhered to medication instructions. The adherent group was more likely to have received written instructions when prescribed medication, compared to the non-adherent group (79.4% vs 55.9%, p = 0.068). Those who perceived that hypertension needs lifelong treatment were significantly more likely to adhere to the medication regimen (p = 0.028). CONCLUSIONS: Medication adherence was present among 50% of outpatients with hypertension who visited a district hospital. Therefore, providing written instructions to patients would be effective for improving medication adherence.
