Prevalence and Risk Factors for Blastocystis Infection Among Children and Caregivers in a Child Care Center, Bangkok, Thailand.

ABSTRACT: In September 2009, a cross-sectional study was conducted to evaluate parasitic infections in a child care center in Khlong Toei, Bangkok, Thailand. Of 503 children and staff members, 258 (51.3%) stool samples and questionnaires were obtained. The most common parasitic infection was Blastocystis sp. (13.6%). Blastocystis sp. subtype 3 was predominantly found (80.0%), followed by subtypes 2 (12.0%) and 1 (8.0%). The prevalence of Blastocystis infection varied among different age groups. The prevalence of Blastocystis infection in non-HIV-infected children aged < 10 and 10-19 years were 14.5% and 10.3%, respectively, which were not significantly different. All 31 HIV-infected children were not infected with Blastocystis sp. The most likely reason could be the result of properly using prevention measures for this specific group.

Project description:BackgroundBlastocystis sp. is the most common intestinal parasite of humans. Despite its potential public health impact, epidemiological data regarding the prevalence and molecular subtype distribution of Blastocystis sp. in Europe are rarely reported. Therefore, the first multi-center epidemiological survey performed in Europe was conducted in France to diagnose and subtype Blastocystis sp. and to identify risk factors for infection.MethodsStool samples from 788 patients were collected either in summer or winter in 11 hospitals throughout France together with patient data. All stool samples were tested for the presence of Blastocystis sp. by quantitative PCR targeting the SSU rDNA gene. Positive samples were sequenced to determine the distribution of the subtypes in our cohort. Statistical analyses were performed to identify potential risk factors for infection.ResultsUsing quantitative PCR, the overall prevalence of Blastocystis sp. was shown to reach 18.1 %. The prevalence was significantly higher in summer (23.2 %) than in winter (13.7 %). Travellers or subjects infected with other enteric parasites were significantly more infected by Blastocystis sp. than non-travellers or subjects free of other enteric parasites, respectively. Different age-related epidemiological patterns were also highlighted from our data. The prevalence of Blastocystis sp. was not significantly higher in patients with digestive symptoms or diagnosed with chronic bowel diseases. Among symptomatic patients, Blastocystis sp. infection was significantly associated with abdominal pain. Gender, socioeconomic status, and immune status were not identified as potential risk factors associated with infection. Among a total of 141 subtyped isolates, subtype 3 was predominant (43.3 %), followed by subtype 1 and subtype 4 (20 %), subtype 2 (12.8 %), subtype 6 and subtype 7 (2.1 %). No association between ST and clinical symptoms was statistically evidenced.ConclusionsA high prevalence of Blastocystis sp. infection was found in our French patient population. Seasonal impact on the prevalence of Blastocystis sp. was highlighted and recent travels and age were identified as main risk factors for infection. Most cases were caused by subtypes 1 to 4, with a predominance of subtype 3. Large variations in both prevalence and ST distribution between hospitals were also observed, suggesting distinct reservoirs and transmission sources of the parasite.

Project description:BackgroundHealthcare workers (HCW), who are crucial workforce, have experienced stress during the COVID-19 pandemic. They have been learning to fight against and support patients as much as possible. Thus, this study aims to account for the psychological impact of the COVID-19 outbreaks on the healthcare workers of medical school hospitals in terms of their perceived stress and coping styles.MethodThis cross-sectional study was conducted from June to August, 2021. 517 HCWs self-administered the online survey. Perceived Stress Scale (PSS-10) in Thai-version was used to examine the perceived stress symptoms. Brief-COPE score was used to determine the coping strategies. Independent sample t-test, one-way analysis of variance (ANOVA), and multivariable regression analysis were utilized. The level of significance was set at p-value < 0.05.ResultThe prevalence of perceived stress among the HCWs was 41.97%. Coping strategies were used to deal with stress during the outbreak for problem-solving (Mean ± SD = 0.25 ± 0.60) and positive attitude (Mean ± SD = 2.85 ± 0.62). Significant difference was observed in the use of coping strategies among those who differ in marital status (F2, 514 = 7.234, p-value = 0.001), having children (t515 = -4.175, p-value < 0.001), and days off (t515 = -1.992, p-value = 0.047). Multivariable regression analysis reported who those perceived stress symptoms using social support more than those normal stress (AOR 1.54, 95% CI 1.070-2.236, p-value = 0.02). The perceived stress symptoms group used the avoidance strategy 2.03 times more than the other group (AOR 2.03, 95% CI 1.406-2.934, p-value < 0.001). Interestingly, the participants who perceived stress symptoms applied a positive attitude strategy lesser than those who experienced normal stress (57.5%) (AOR 0.42, 95% CI 0.307-0.590, p-value < 0.001).ConclusionThe impact of the COVID-19 pandemic on mental distress remains. The findings of this study suggest further study to assess the HCWs' stress after the pandemic. HCWs should consider merging each of the coping strategies to balance work and lifestyle in pandemic situations.
