Methods: Percutaneous transhepatic self-expandable metal stent (MS, n=61) or 10F plastic stent (PS, n=34) implantation was performed in 95 patients with malignant biliary obstruction in three hospitals of Guangdong province. All patients were followed up until death or at least one year after the procedure. Kaplan-Meier analysis was used to compare the survival and stent patency rates of the patients in the two groups. CERs of two groups were calculated. The main indexes were CERsurvival period (total cost/median survival period), CERpatency period (total cost/median patency period). Results: The total costs of treatment were 53177±3139 yuan (RMB) in MS group and 42564±4950 yuan (RMB) in PS group respectively (P>0.05). CER in MS group was superior to that in PS group (CERsurvival period was 237.4 yuan /d vs 452.6 yuan /d, respectively; CERpatency period was 231.2 yuan /d vs 472.9 yuan /d, respectively). Conclusion: The metal stent implantation is superior to the plastic stent in the CER for treatment of malignant biliary obstruction.展开更多

However, there is a lack of higher-level evidence concerning the intervention efficacy. This study aimed to determine the efficacy of an intervention to reduce the number of heat-related illnesses. Methods A quasi-experimental design was employed by two cross-sectional surveys in the year 2024 and 2015, including 2,240 participants and 2,356 participants, respectively. Each survey was designed to include one control group and one intervention group, which conducted in Licheng, China. A representative sample was selected using a multistage sampling method. Data, collected from questionnaires about heat waves in 2014 and 2015, were analyzed using a difference-in-difference analysis and cost effectiveness analysis. Outcomes included changes in the prevalence of heat-related illnesses and cost-effectiveness variables. Results Relative to the control participants, the prevalence of heat-related illness in the intervention participants decreased to a greater extent in rural areas than in urban areas （OR=0.495 vs. OR=2.282）. Moreover, the cost-effectiveness ratio in the intervention group was tess than that in the control group （usS25.06 vs. us$25.69 per participant）. Furthermore, to avoid one additional patient, the incremental cost-effectiveness ratio showed that an additional USS14.47 would be needed for the intervention compared to when no intervention was applied. Conclusion The intervention program may be considered a worthwhile investment for rural areas that are more likely to experience heat waves. Meanwhile, corresponding improving measures should be presented towards urban areas. Future research should examine whether the intervention strategies could be spread out in other domestic or international regions where heat waves are usually experienced.展开更多

This shortfall has an expected mortality of about 500 million people. To prevent such mass starvation, alternate foods can be deployed that utilize stored biomass. This study developed a model with literature values for variables and, where no values existed,used large error bounds to recognize uncertainty. Then Monte Carlo analysis was performed on three interventions: planning, research, and development. The results show that even the upper bound of USD 400 per life saved by these interventions is far lower than what is typically paid to save a life in a less-developed country. Furthermore, every day of delay on the implementation of these interventions costs 100–40,000 expected lives(number of lives saved multiplied by the probability that alternate foods would be required). These interventions plus training would save 1–300 million expected lives. In general, these solutions would reduce the possibility of civilization collapse, could assist in providing food outside of catastrophic situations, and would result in billions of dollars per year of return.展开更多

Even in India, nationwide interventions targeting safe mother and newborn care have not yielded the desired impact, indicating the necessity to combat neonatal mortality rate at population specific level. The objective of this study is to identify the newborn care practices and beliefs, analyze their harmful or beneficial characteristics, describe the deviations from the essential newborn care practices during hospital/home delivery, explain barriers to care seeking and identify areas of potential resistance for behavior change;and utilize study findings to tailor-make cost-effective essential newborn care package. The study uses qualitative data from in-depth interview of mothers who had experienced neonatal death and key-informant interviews with healthcare personnel and birth attendants. 33 cases were randomly selected from the registered neonatal deaths across Bharuch district of Gujarat, India. Key finding of this study is less prevalent practice of essential newborn care among all cases irrespective of place of delivery and the health-care personnel facilitating delivery. Habitual traditional/tribal newborn care methods challenge the practice of prescribed essential newborn care. Clustering of deaths in few households added significantly to the existing burden of neonatal deaths, attributed to superstition “Ratewa” by tribal. Study has concluded that the introduction and implementation of essential newborn care at hospital and community/ household level are the need of the hour. Quality home based neonatal care through cost effective interventions is deemed necessary where accessing institutional care is not possible in the immediate term. Community health workers can contribute to the eradication of harmful newborn care practices and the sustenance of essential practices through community education and behavior change communication.展开更多
