As many countries implement different programs aimed at eliminating malaria, attention should be given to asymptomatic carriers that may interrupt the progress. This was a community-based cross-sectional study conducted in Tanzania from December 2022 to July 2023 within 4 villages from each of the 3 regions, Geita and Kigoma, which are high malaria transmission, and Arusha, which is low transmission. Malaria was diagnosed in asymptomatic individuals aged 1 year and older using the malaria rapid diagnostic test and light microscope. A total of 2,365 of 3,489 (67.9%) participants were enrolled from high-transmission villages. The overall prevalence was 25.5% and 15.8% by malaria rapid diagnostic test and light microscope, respectively. Using the respective tools, the prevalence was significantly higher at 35.6% (confidence interval (CI)=23.6–49.9) and 23.1% (CI=16.2–35.1) in the high-transmission regions (Geita and Kigoma) compared with 2.9% (CI=1.1–3.5) and 1.1% (CI=0.7–1.8) in the low-transmission region (Arusha). Children younger than 15 years and males accounted for the greatest proportion of infections. In the study area, the prevalence of asymptomatic cases was higher than that of reported symptomatic cases in health facilities. We hypothesize that these parasite reservoirs may contribute to the persistence of malaria in the country. Therefore, to achieve comprehensive malaria control in the country, the surveillance and screening of asymptomatic malaria cases are vital.

Purpose:
This study aimed to explore customer perspectives of nursing services in tertiary hospitals.
Methods:
The data comprised mobile Voice Of Customer (VOC) data related to “nursing” or “nurses” generated from June 25, 2019, to December 31, 2022, in a tertiary hospital. A total of 44,727 VOC data points were collected, of which 4,040 were selected for the final analysis. Text network analysis and topic modeling were conducted using NetMiner 4.5.1.
Results:
Topic modeling identified five topics for positive aspects and four topics for areas requiring improvement.The positive aspects were: 1) sincere nursing care; 2) rapid response from professional medical staff; 3) teamwork for delivering customer-centric services; 4) provision and coordination of system-based healthcare services; and 5) customer-focused responsiveness. The areas requiring improvement were: 1) demand for skilled nursing care tailored to customer expectations; 2) demand for enhanced communication and reduced mechanical responses; 3) demand for appropriate handling of diverse situations; and 4) demand for overall improvements to the healthcare system, including reservation systems.
Conclusion
These results may be used to enhance customer and patient experiences in tertiary hospitals and are necessary for utilization from a hospital management perspective.

Hypovolemic shock and septic shock present similar symptoms, such as increased heart rate and decreased blood pressure. However, the two conditions have different causes, mechanisms, and treatment approaches. Early differentiation between the two conditions can have a positive impact on patient prognosis. In this case, the patient underwent a right ovarian cystectomy due to a teratoma torsion during a previous pregnancy, followed by treatment for a postoperative infection. While recovering, the patient underwent an emergency cesarean section due to sudden severe abdominal pain. After the surgery, unstable vital signs were suggestive of hypovolemia due to massive bleeding from the cesarean section. Therefore, fluid infusion and blood transfusion were initiated. The vital signs did not improve. So, the patient was reassessed. Body temperature and the previously elevated C-reactive protein levels were remeasured. The results of the reassessment indicated a septic condition due to previous infection. The patient was prescribed additional vasopressors and antibiotics for the following week. Subsequently, the patient’s vital signs stabilized, and the treatment was discontinued.
