Maternal and Neonatal Outcomes of Pregnant Women with Abnormal 50 g Glucose Challenge Tests in Nakhon Si Thammarat, Thailand: A Retrospective Study

(1) Background: An abnormal 50 g glucose challenge test (50 g GCT) during pregnancy, even without a diagnosis of gestational diabetes mellitus (GDM), may result in undesirable obstetric and neonatal outcomes. This study sought to evaluate the outcomes in pregnant women with abnormal 50 g GCT in secondary care hospitals in Thailand. (2) Methods: A total of 1129 cases of pregnant women with abnormal 50 g GCT results who delivered between January 2018 and December 2020 at Thasala, Sichon, and Thungsong hospitals were retrospectively reviewed and divided into three groups: abnormal 50 g GCT and normal 100 g oral OGTT (Group 1; n = 397 cases), abnormal 50 g GCT and one abnormal 100 g OGTT value (Group 2; n = 452 cases), and GDM (Group 3; n = 307 cases). (3) Results: Cesarean section rates in group 3 (61.9%) were statistically higher than those in groups 1 (43.6%) and 2 (49.4%) (p < 0.001). In addition, the highest rate of birth asphyxia was found in group 2 (5.9%), which was significantly higher than that in Groups 1 (1.8%) and 3 (3.3%) (p = 0.007). (4) Conclusions: Pregnant women with abnormal 50 g GCTs without a diagnosis of GDM had undesirable maternal and neonatal outcomes, as well as those who had GDM, suggesting that healthcare providers should closely monitor them throughout pregnancy and the postpartum period.

Unhealthy Dietary Patterns and Their Associations with Sociodemographic Factors as Predictors among Underweight and Overweight Adolescents in Southern Thailand

(1) Background: Adolescence is a critical developmental phase; dietary intake and nutritional status significantly impact health outcomes. (2) Objective: This cross-sectional study investigated dietary patterns (DPs) and the association between sociodemographic factors and unhealthy DPs among adolescents in Thailand. (3) Methods: A multi-stage sampling selected 1480 participants from three public high schools in Nakhon Si Thammarat province. A food frequency questionnaire assessed dietary habits, and principal component analysis was used to identify DPs. Multinomial logistic regression examined the association between sociodemographic factors and DPs. (4) Results: The findings show that 25.9% of adolescents were underweight, 14.7% were overweight, and 5.8% were obese. Three DPs were identified: a healthy 'protein and vegetables' pattern and two unhealthy patterns: 'snacks' and 'processed foods', which explained 12.49%, 10.37%, and 7.07% of the dietary variance, respectively. Among underweight adolescents, higher snack consumption was associated with being younger (odds ratio (OR) = 3.24) and receiving a higher daily allowance (OR = 3.43). Additionally, female adolescents who engaged in frequent exercise had a 2.15 times higher intake of processed foods. Among overweight adolescents, higher snack intake was linked to being younger (OR = 8.65) and having larger families (OR = 6.37). Moreover, an increased daily allowance was associated with higher consumption of processed foods (OR = 11.47). (5) Conclusion: This study underscores the socio-demographic influence on unhealthy DPs. Insights can guide targeted interventions to foster healthier dietary habits during adolescence.

Impact of the COVID-19 Pandemic on the Female Sexual Function Index and Female Behavioral Changes: A Cross-Sectional Survey Study in Thailand

Sexual health alterations are associated with disasters. Consequently, the COVID-19 pandemic may affect female sexual function. This study aimed to determine the COVID-19 pandemic effect on female sexual function and to know the risk of female sexual dysfunction. This online, cross-sectional, observational research was conducted during the pandemic period. A logistic regression model was used to investigate the associations between outcomes and potential risk factors. In total, 432 sexually active women participating in the region affected by the COVID-19 pandemic were analyzed. The overall findings of our study are that 60 percent of females were at risk for female sexual dysfunction. The average FSFI score was 21.27 ± 7.17. Comparing female sexual behavior before and during the COVID-19 pandemic reveals a significant decrease in the frequency of having sex per week, foreplay duration, and coital duration. In the multivariate analysis, the factors associated with the development of RFSD are age greater than 45 years (adjusted odds ratios (AOR) 15.09, 95% confidence interval (CI) 3.67-62.07), body mass index (BMI) greater than 25 (AOR 3.26, 95%CI 1.23-8.67), jobs as a healthcare provider (AOR 8.45, 95%CI 3.66-19.53), previous COVID-19 infection within the previous three months (AOR 36.81, 95%CI 10.93-123.98), and screened-positive anxiety (AOR 13.07, 95%CI 4.75-35.94). COVID-19 influences female sexual behavior and may increase the risk of sexual dysfunction in women. Concern for the effects of female sexual quality of life in high-risk individuals is essential.

Effects of an online yoga program on anthropometric parameters among overweight female students during the COVID-19 pandemic

The coronavirus disease 2019 (COVID-19) outbreak is a public health concern. However, stay-at-home regulations to prevent disease spread increased sedentary behavior with unintended adverse outcomes. Overweight is a major global health issue, and standard treatments have a poor track record of long-term effectiveness. The purpose of this study was to evaluate how online yoga affected participants who were overweight in terms of anthropometric measurements. The study, which was designed as a experimental study, enrolled sixty overweight adolescents. The participants were divided into two groups: a control group (n = 30) and an intervention group (n = 30) who performed an online yoga home exercise program comprising basic yoga practice with 15 poses and minimal rest periods on Monday Wednesday and Friday, from 5.00 to 5.45 pm for 12 weeks. The intensity of the exercise was 65–75 percent of maximum heart rate (MHR). Anthropometric parameters, including body weight (BW), body mass index (BMI), body circumference measurements (BCM), and resting heart rate (RHR) were assessed. All parameters were measured at weeks 0, 8, and 12. Within group and between group comparisons were performed. The results revealed improved BW, BMI, BCM, and RHR in the intervention group; the median BW and BMI of the intervention group was significantly decreased at week 12, and the BCM of the intervention group showed a significant decrease in the chest, waist, hip, and thigh. This declining trend started from week 8. This 12-week online yoga program decreased BW, BMI, BCM, and RHR, which indicates that practicing yoga at home is effective on anthropometric parameters and may be an alternative therapy for health promotion and controlling body weight during the COVID-19 pandemic. However, an appropriate and continuous exercise program must be followed.

Seroprevalence of anti-Toxocara canis antibodies and associated risk factors among dog owners in the rural community of Nakhon Si Thammarat province, southern Thailand

Background

Human toxocariasis is a zoonotic parasitic disease caused by the Toxocara canis and T. cati nematodes larvae. Dog owners are at a higher risk of acquiring T. canis infection, and there is no available evidence regarding the seroprevalence of T. canis infection among dog owners in Thailand. Therefore, this study aimed to investigate the seroprevalence of T. canis infection and associated risk factors among dog owners in rural areas of Thailand.

Methods

A total of 132 dog owners, including 25 men and 107 women, were recruited for this study. Serum anti-T. canis IgG antibodies were detected using a commercial enzyme-linked immunosorbent assay (ELISA) kit, and information on risk factors was collected using a questionnaire. In addition, hematological parameters were analyzed by the auto hematology analyzer. Risk variables associated with T. canis infection were investigated using univariate and multivariate logistic regression models.

Results

The overall seroprevalence of T. canis was 76.5% (101/132). Men were more likely to be infected with T. canis than women. Univariate analysis revealed that dog owners who did not practice handwashing before meals (p = 0.005) or after contact with soil (p = 0.035) or dogs (p = 0.049) had a substantially higher risk of acquiring T. canis infection. After adjusting for confounders, not practicing handwashing before meals remained a significant risk factor for T. canis infection (p = 0.038). The mean number of eosinophils was significantly higher in the seropositive group than in the seronegative group.

Conclusions

This is the first serological report of T. canis infection among dog owners reflecting the high rate of T. canis seropositivity in rural areas of southern Thailand. This study also provides group-specific data concerning modifiable risk behaviors for more effective T. canis infection control and prevention strategies in Thailand.

Rub and Rinse Contact Lenses Before Wearing as a Protective Regimen Against Contact Lens-Related Eye Infections

Purpose

Data on contact lens (CL) users in Thailand are limited, and previous reports have mainly focused on young populations. This study aims to determine demographic data, hygienic behaviour, and complications related to the usage of CLs in the general population.

Methods

This was a cross-sectional survey conducted from November 2020 to March 2021 using an anonymous questionnaire. Information on the demographic traits of the participants, characteristics of CL use, and CL care behaviours was collected. The responses were summarised and presented as a total behaviour score. Regression analysis was performed to evaluate the potential risk factors for a history of CL-related eye infections.

Results

A total of 134 CL wearers were recruited. Of all the participants, 83.58% were female and 16.42% were male. The average age was 31.14±10.69 years old. The total behaviour score showed that 62.69% of the population had good CL behaviour, while 37.31% exhibited poor CL behaviour. More than 50% of participants practised appropriate CL handling. Common unfavourable behaviours (>50%) reported were not using CL care solution to clean the storage case, not rubbing and rinsing the lens before storage, exposure to water during wear, use of makeup around the ocular area, and missing annual eye exams. Other less common but important instances of mishandling included using tap water to clean the lenses, topping off old CL solution, and exceeding the recommended planned-replacement period. However, no behaviours were significantly associated with a history of CL-related eye infections. Rubbing and rinsing CLs before wearing them was found to be a protective factor against a history of eye infections.

Conclusion

Rubbing and rinsing CLs before wearing should be mentioned as an additional recommendation for the user.

Bacterial microbiota of the contact lens surface and associated care behaviours

Introduction

Contact lens (CL) wear has been reported to cause changes to the microbiome of the ocular surface. More insight into the alteration of this microenvironment can help to understand the pathogenesis of CL-related eye infections. Knowledge of the relationship between the CL wearer's behaviours and pathogens would help health care providers focus on each step of proper CL care. This study aims to determine the behaviours that might be associated with the community of bacteria on CL.

Methods

A cross-sectional design was performed using anonymous questionnaires to obtain demographic data and assess hygiene practices among volunteering wearers. The CLs used were collected to evaluate the prevalence of pathogenic bacteria associated with ocular infections by PCR and microbiota analysis.

Results

The bacterial microbiota study revealed a total of 19 genera and 26 isolated strains from 20 eligible CLs. Enterobacter, Staphylococcus, and Achromobacter were the main genus in this subject population. Staphylococcus pasteuri and Achromobacter agilis were the most common pathogens at 65% and 35%, respectively. Enterobacter mori, a nonpathogenic organism, was found to be the most predominant strain, accounting for 27.51% of the total bacterial constituents. The risk behaviour of CL wear that was significantly associated with A. agilis contamination was cleaning the CL case with tap water (P value = 0.04).

Conclusions

This is the first study focusing on the association between the culture selected microbial community on the CL surface and compehensive behavioural characteristics. Environmental contamination was the main source of microbes found on CL surfaces. An emphasis in patient education should be placed on careful handling during the CL care routine and managing the hygiene of the surroundings.

Optimization of Culture Protocols to Isolate Leptospira spp. from Environmental Water, Field Investigation, and Identification of Factors Associated with the Presence of Leptospira spp. in the Environment

The successful culture of Leptospira spp. from the environment is challenging. Here, we optimized the isolation of Leptospira spp. from water samples spiked with different species and initial concentrations of this organism. The time periods between water sampling and the isolation process were varied (0, 2, and 4 weeks). Bacterial cultures were observed under a microscope, and cultures were graded for cell density, weekly, for 12 weeks. Most pathogenic Leptospira spp. were difficult to culture under all conditions. All conditions of water samples spiked with novel species of Leptospira subclade P1 were culture positive within 2 weeks. For Leptospira subclade P2, storing samples for 2 weeks prior to isolation resulted in more successful isolation compared with isolation after other storage conditions. For subclade S1, all samples with initial bacterial concentrations of more than 10³ colonies/mL, under all storage conditions, were successfully cultured. These results suggest that storing contaminated water samples for 2 to 4 weeks in the dark at an ambient temperature prior to culturing can improve the isolation of Leptospira spp. from the samples. We implemented this protocol and collected water samples from natural sources accessed by both humans and animals. Leptospira spp. was identified in 32% (35/109) of water samples. The animal species using a water source influenced the likelihood of water samples being contaminated with Leptospira spp. Cultures of Leptospira spp. from environmental samples can provide useful information for understanding the complex interactions between humans, animals and the environment in the transmission of leptospirosis.
