Abstract

Soil-transmitted helminth (STH) prevalence is high worldwide. School-aged children are at risk of infection due to poor self-hygiene and contaminated soil and water. Anemia is caused by infection in children, and it affects cognitive development, physical development, and school performance. To ascertain the relationship and distribution of STH and anemia in elementary school students, as the cross-sectional objectives. Students from SDN 96 and 97 Palembang participated in the study. Using stratified random sampling, 84 students from grades 4, 5, and 6 were chosen at random. Anemia is diagnosed through a test using the Quick Check hemoglobin method. They discovered that 40.5 percent of students had intestinal worms, 15.5 percent were anemic, and 11.8 percent were both anemic and worm-infected. A p-value of 0.438 was obtained from the chi-square bivariate analysis. There is no link between STH and anemia.

Abstract

Shift work is a method of allocating work time to different workgroups. Fatigue is defined as an abnormal sensation of tiredness, sluggishness, or a lack of desire to engage in activities, which results in stress, depression, or other negative emotions. In order to satisfy patients within 24 hours, hospitals must organize nurses by shift. The goal of this study at Muhammadiyah Palembang Hospital was to see if there was a link between shift work and fatigue in pediatric and internal ward nurses. This cross-sectional and analytic study entailed 26 respondents from the total sampling method used. In this study, those who worked shifts included those who worked in the morning (12 respondents (46.2 %), evening (8 respondents (30.8%), and night (6 respondents (23.1 %). Fatigue has been linked to 38% of RSMP's overworked pediatric ward nurses and interna, with a p-value of 0.029. The hospital should provide rest periods for nurses, especially those who work the last shift because they must adapt during the night.

Abstract

Corona Virus Disease 2019 (COVID-19) is an infectious disease that has been designated as a worldwide pandemic. Symptoms of Covid-19 are not only respiratory symptoms but also extrapulmonary symptoms, including the discovery of impaired liver function in the form of increased transaminase enzymes. Therefore, this study was conducted to see the correlation of transaminase enzymes with the prognosis of COVID-19 patients treated in the Intensive Care Unit (ICU) Dr. Wahidin Sudirohusodo Hospital. The study was conducted on June to August 2021. The cross-sectional analytical research method used retrospective medical record data for the period from July to December 2020 with a sample of 137 patients with COVID-19 confirmed. From the results of the Pearson test, patients with increased SGOT were associated with a mortality prognosis (p=0.000, p<0.05) with a correlation coefficient (r) of -0.383 and an increase in SGPT were associated with a mortality prognosis (p=0.013, p<0.05) with a correlation coefficient (r) of -0.211. From the results of the Kruskal Wallis test, there were differences in prognosis in patients with increased SGOT and SGPT grades 1,2,3, and 4 (p = 0.000 and p = 0.028). There is a correlation between the increased transaminase enzymes with the prognosis of the patient's mortality. Patients with severe elevated SGOT and SGPT enzymes had a greater prognosis of mortality than those with mild enzyme elevations. Extrapulmonary symptoms of stroke were associated with increased SGOT and myocardial infarction symptoms, and nephropathy was associated with increased SGOT and SGPT. Comorbid coronary artery disease and hepatitis were associated with increased SGOT and SGPT.
