RESUMEN
The aim of this study was to explore the risk of Simplex virus type 1 (HSV-1) in patients with insomnia. This study applied a population-based retrospective cohort design. A total of 50,210 patients agedâ ≥â 20 years who had received a diagnosis of insomnia between 2000 and 2015. They were identified according to the corresponding International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) code. The control cohort comprised 100,420 age-matched and sex-matched patients. Data from the Taiwan National Health Insurance Research Database were employed from 2000 to 2015. The overall incidence of HSV-1 in the insomnia cohort was significantly higher than that in the comparison cohort (3.10 vs 0.33 per 1000 person-years). Patients with insomnia had a higher risk of HSV-1 infection, compared with the comparisons (hazard ratio (HR)â =â 4.33, 95% confidence interval (CI) 2.18-5.58). For individuals divided into 3 age groups (≤40, 41-65, andâ >65 years old), the HSV-1 infection risk of the insomnia cohort was significantly greater than that of the comparisons. As the duration of insomnia increases, the risk of HSV-1 occurrence decreases.

This study aims to analyze the prevalence of low muscle mass (LMM) and its associated factors among community-dwelling patients with type 2 diabetes (T2D). A retrospective design was employed to analyze the body composition of 2404 adults with T2D aged 18 years and older. LMM was defined as a skeletal muscle indexâ <â 7.0 kg/m2 for males and skeletal muscle indexâ <â 5.7 kg/m2 for females by bioelectrical impedance analyzer (InBody 770, Korea). Multivariable logistic regression was used to identify the factors related to LMM. The overall prevalence of LMM was 28%. After adjusting for multivariate odds ratios, factors significantly associated with LMM in patients with diabetes include being older than 75 years, female, having a body mass index of <18 kg/m2, and increased percent body fat. We recommend regular LMM evaluations for T2D patients with the previously mentioned characteristics as part of diabetes care.

An integrated, remotely sensed approach to assess land-use and land-cover change (LULCC) dynamics plays an important role in environmental monitoring, management, and policy development. In this study, we utilized the advantage of land-cover seasonality, canopy height, and spectral characteristics to develop a phenology-based classification model (PCM) for mapping the annual LULCC in our study areas. Monthly analysis of normalized difference vegetation index (NDVI) and near-infrared (NIR) values derived from SPOT images enabled the detection of temporal characteristics of each land type, serving as crucial indices for land type classification. The integration of normalized difference built-up index (NDBI) derived from Landsat images and airborne LiDAR canopy height into the PCM resulted in an overall performance of 0.85, slightly surpassing that of random forest analysis or principal component analysis. The development of PCM can reduce the time and effort required for manual classification and capture annual LULCC changes among five major land types: forests, built-up land, inland water, agriculture land, and grassland/shrubs. The gross change LULCC analysis for the Taoyuan Tableland demonstrated fluctuations in land types over the study period (2013 to 2022). A negative correlation (r = - 0.79) in area changes between grassland/shrubs and agricultural land and a positive correlation (r = 0.47) between irrigation ponds and agricultural land were found. Event-based LULCC analysis for Taipei City demonstrated a balance between urbanization and urban greening, with the number of urbanization events becoming comparable to urban greening events when the spatial extent of LULCC events exceeds 1000 m2. Besides, small-scale urban greening events are frequently discovered and distributed throughout the metropolitan area of Taipei City, emphasizing the localized nature of urban greening events.

Sleep problems was associated with increased risk for herpes zoster (HZ). This study examined subjects with insomnia or a combination of insomnia and depression and their risk of HZ. This retrospective cohort study included a total of 47,256 participants, with a control comprising 31,504 age- and sex-matched patients. Clinical data from 2000 to 2013 in the Taiwan National Health Insurance Research Database were used for analysis. Insomnia, depression, and HZ were defined according to the International Classification of Diseases, Ninth Revision, Clinical Modification. Subjects with insomnia had a significantly higher incidence of HZ (2.77 per 1000 person-years) than the controls (1.81 per 1000 person-years) as well as a higher risk of developing HZ (adjusted hazard ratio (AHR) = 1.62, 95% confidence interval (CI) = 1.35-1.93). Results shown subjects with insomnia durations of < 4 years, 4-6 years, and > 6 years had a significantly higher risk of HZ compared with the controls (AHR: 6.69, 95% CI 4.44-9.39; AHR: 4.42, 95% CI 3.07-6.36; AHR:1.38, 95% CI 1.14-1.87, respectively). We found a significantly higher risk of HZ in subjects with both insomnia and depression (AHR = 4.95; 95% CI = 3.99-7.02) than in those without related conditions. Patients with insomnia, and even more so those with comorbid depression, had a higher risk of developing HZ. This indicates a joint effect of insomnia and depression on HZ.
RESUMEN
AIM: The coronavirus disease 2019 (COVID-19) pandemic has had a substantial effect on frontline health care workers and caused public health nurses (PHNs) to come under various forms of pressure. PHNs face high-risk challenges in their work environment, and their professional commitment and adaptability are key concerns. The aim of this qualitative study was to describe the experiences of PHNs during the COVID-19 outbreak. METHODS/DESIGN: Twenty PHNs who worked during the COVID-19 outbreak were recruited from seven public health centres through posters. Data were collected through in-depth interviews that comprised semi-structured and open-ended questions; subsequently, the data were analysed through content analysis. RESULTS: Three themes emerged from the study findings, namely (1) the disorderliness of COVID-19 pandemic prevention work, (2) managing stress and fear, and (3) the establishment of a new normal. Because of the severity of the pandemic, the workload and stress associated with epidemic prevention policies continue to increase. PHNs may infect their family members and experience a sense of alienation and distance. They must also deal with irrationality and reactions in the people within their community. CONCLUSION: Health department directors and policymakers should provide the necessary support and assistance to frontline pandemic prevention workers to increase the efficiency of pandemic prevention efforts. PATIENT OR PUBLIC CONTRIBUTION: The participants agreed to participate in the qualitative study during the study period.
