Vagus nerve stimulation(VNS)and stroke:Stroke is the second leading cause of death and the third leading cause of disability worldwide(Baig et al.,2023).There have been significant paradigm shifts in the management of acute ischemic stroke through mechanical *** chronic ischemic stroke,invasive VNS paired with rehabilitation is associated with a significant increase in upper limb motor recovery and is FDA-approved(Baig et al.,2023).There are no treatments of similar efficacy in acute intracerebral hemorrhage(ICH)where several promising trials,e.g.,TICH-2,STOP-AUST,and TRAIGE did not show improvements in functional outcomes(Puy et al.,2023).

Resettlement and relocation are among the most difficult policies to put into practice, but they may be the best ways to minimize future risks to settlements exposed to natural hazards both before and after disaster events. As climate-related disasters and forced migration become increasingly common worldwide, governments, humanitarian or development actors,and policymakers must now prioritize the implementation of a dignified and effective resettlement program as part of their planning and management responsibilities. Much of this effectiveness depends on the stakeholders and beneficiaries' understanding and knowledge of the different resettlement phases, culture and customs of affected populations, activities, and the associated implementation challenges, costs, and benefits. Serious games are used in a variety of contexts to increase awareness, train and build capacity in stakeholders and beneficiaries. This article presents a serious game developed to educate practitioners, local agencies, students, and the public to understand the complexities and challenges involved in a successful resettlement. The game is based on a real proposed resettlement project initiated in the Chiradzulu District in southern Malawi after Cyclone Freddy in March 2023, which caused widespread flooding and landslides, forcing some villages to relocate permanently. The progression in the Road to Resettlement Game consists of six primary levels: land and site preparation, housing and livelihood, water, sanitation, and hygiene, health, education, and protection. These levels are meant to be completed in a sequence that adheres to the principles of resettlement. By engaging in the serious table-top board game, players gain an understanding of the resettlement activities, their sequence, and the associated practical(technical and social) and financial challenges.

BACKGROUND:The prevalence of gallstones is low in *** Iran,many factors influence the prevalence of this *** aim of this study was to determine the prevalence of gallbladder stones and their chemical characteristics in a population by the study of cadavers. METHODS:In this cross-sectional study,autopsies were performed on 253 cadavers of more than 13 years *** cadavers were studied to determine the number,location of stone formation,chemical composition,dry weight,and mean diameter of stones in the gallbladder and common bile duct. RESULTS:The prevalence of gallstone disease in these cadavers was 6.3%(men 4.7%,women 8.6%,not significantly different,P=0.216).There was a positive relationship between the age and prevalence of gallstone disease(P=0.033).The most common stone compositions were cholesterol and *** mean diameter (P=0.0058)and dry weight(P<0.0001)of stones were higher in the gallbladder than in the common bile duct. Positive relations between the amount of oxalate and mean diameter,and between the amount of oxalate and mean dry weight of gallstones were found,but the relationship between the amount of cholesterol and mean diameter was inverse. CONCLUSIONS:The prevalence of gallstones differed among age *** and dry weight of gallstones were dependent on location of stone formation and chemical composition.
