Hepatitis D virus （HDV） infection， the most severe form of viral hepatitis， remains underrecognized in the Asia due to inconsistent screening and limited surveillance. This systematic review （1970—2025） stratified HDV prevalence by population subgroups： community， hospital-based， and high-risk.Community studies showed high prevalence in Pakistan， Kazakhstan， and Kyrgyzstan； hospital cohorts revealed hyperendemicity in Mongolia and Uzbekistan； high-risk populations showed concentrated transmission in ［Hong Kong， China］， ［Taiwan， China］， Vietnam， and Sultanate of Oman. Many countries and regions lacked subgroup-specific data.The uneven， population-dependent burden underscores HDV as a major driver of advanced liver disease in Central and South Asia. Routine HDV screening and RNA-based diagnostics are essential to define burden and advance WHO 2030 elimination targets.¹

Background: Advancements in surgery, chemotherapy, and radiotherapy have improved survivalfor brain tumor patients, increasing the risk of second primary tumors (SPTs) among long-term survivors. This study examines the types and risks of SPTs in brain tumor patients presenting at a tertiary care hospital. Methods: This single-center, retrospective study explored occurrences of SPTs following prima-ry brain tumors and occurrences of brain tumors as SPTs following primary extra neural tumors. A total of 41 patients were included and analyzed presenting with histologically confirmed SPTs between 1st January 2000 and 31st December 2020. Results: The study included 41 patients with SPTs, primarily female (65.9%). Of these, 20 pa-tients (48.7%) developed SPTs after a primary brain tumor, while 21 patients (51.2%) developed brain tumors as SPTs after extra-neural tumors. Among patients who developed SPTs after brain tumors (n=20), meningioma (n=8, 40.0%) and pituitary adenoma (n=6, 30.0%) were the most prevalent first primary tumors (FPTs) while breast tumors predominated as SPTs (n=4, 20.0%). Survival analysis indicated younger mean age (44.5 years) for patients marked alive, compared to those marked deceased (57.0 years) and those with unknown outcomes (63.0 years). Conclusion Based on this retrospective analysis, the median age at diagnosis was 44.5 years,with a considerable number of patients (36.6%) having uncertain outcomes at follow-up due to incomplete records. These findings highlight the need for improved follow-up data management to better assess long-term survival in patients with SPTs following brain tumors.

Background: Cognitive decline is commonly seen in brain tumor (BT) patients and is associatedwith a worsened prognosis. Cognitive rehabilitation (CR) for cancer-related cognitive dysfunction has been widely studied for non-central nervous system cancers; however, recent emerging research has commenced documenting CR strategies for BT patients and survivors. Our objective was to review the current literature on various CR modalities in patients and BT survivors. Methods: The review was conducted in accordance with the PRISMA guidelines. The studieson CR were searched across 3 databases using a predefined search strategy. After removing duplicates, performing initial and full-text screenings, and applying inclusion criteria, relevant articles were selected. The demographic details, CR technique, cognitive tasks/tests administered, cognitive functions assessed, follow-up time, and outcomes of the intervention were assessed. Results: A total of 15 studies were included in the review. Neuropsychologist-guided trainingsessions to improve memory, attention, and executive functioning are effective in improving the mentioned domains. Younger and more educated patients benefited the most. Holistic mnemonic training and neurofeedback were not shown to affect overall cognitive functioning. Computer-based training programs showed improvements in executive functions of pediatric BT survivors, however, feasibility studies showed conflicting results. Aerobic exercises improved executive functions and decreased symptoms of the tumor. Both yoga and combined aerobic and strength training improved overall cognitive functioning. Active video gaming may improve motor and process skills; however, no effect was seen on cognitive functioning. Conclusion Neuropsychologic training, computer-based programs, and physical exercise havebeen found effective in improving or preventing decline in cognitive functions of BT patients. Given the limited trials and methodological variations, a standardized CR program cannot be established at present. Ongoing trials are expected to provide valuable data in the near future.

Microangiopathic hemolytic anemia (MAHA) is a rare subtype of hemolytic anemia characterized by elevated hemolytic markers and red blood cell destruction. Though uncommon, MAHA can occur as a complication of acute pancreatitis because of the associated inflammatory response. Patients with MAHA secondary to pancreatitis show favorable outcomes when treated with plasma exchange.This paper presents the case of a patient diagnosed with acute pancreatitis-induced hemolytic anemia and thrombocytopenia, who was managed successfully with plasma exchange, steroids, and rituximab. Clinicians should maintain a high index of suspicion in patients with acute pancreatitis who present with anemia, thrombocytopenia, and schistocytes on peripheral smears, even in the absence of end-organ injuries and with normal ADAMTS13 activity. The early initiation of plasmapheresis can be lifesaving. The timely introduction of rituximab in cases where plasma exchange and steroids are insufficient, despite the ADAMTS13 activity status, may lead to better outcomes.

Objective:To evaluate the impact of short-term exposure to daytime heatwaves, nighttime heatwaves, and compound heatwaves on the risk of road traffic mortality and calculate the attributable mortality burden.Methods:This study collected road traffic mortality data from the Disease Surveillance System in Guangdong, Hunan, Zhejiang, Yunnan, and Jilin Provinces from 2013 to 2018. A time-stratified case-crossover design was used in this study, with the death date for each case serving as the case day. Control days were selected from the same year, month, and day of the week as the case day. A conditional logistic regression model was employed to estimate the cumulative associations of short-term exposure to daytime heatwaves, nighttime heatwaves, and compound heatwaves on the risk of road traffic mortality (lag 0-1 day) and to calculate the attributable fractions (AF).Results:Compared to non-heatwave days, the excess risk ( ER) of road traffic mortality on daytime heatwave days, nighttime heatwave days, and compound heatwave days was 5.3% (95% CI: 0.5%-10.2%), 4.9% (95% CI: 0.5%-9.4%) and 7.5% (95% CI: 2.3%- 12.9%), with corresponding AF of 5.0% (95% CI: 0.5%-9.3%), 4.7% (95% CI: 0.5%-8.6%), and 6.9% (95% CI: 2.3%-11.4%), respectively. Stratified analysis showed that the risk of traffic mortalities caused by daytime heatwaves was higher in females ( ER=15.7%, 95% CI: 5.8%-26.5%) than in males ( ER=1.8%, 95% CI: -3.6%-7.4%). Elderly individuals over 64 years old ( ER=10.9%, 95% CI: 0.3%- 22.6%) had a higher risk of road traffic mortalities from compound heatwaves than those under 45 years old ( ER=2.6%, 95% CI: -5.4%-11.2%). The risk of road traffic injury mortality from motor vehicle accidents caused by compound heatwaves ( ER=16.6%, 95% CI:2.4%-32.7%) was higher than that from non-motor vehicle accidents ( ER=5.7%, 95% CI:0.1%-11.5%). Conclusions:Short-term exposure to daytime heatwaves, nighttime heatwaves, and compound heatwaves was associated with an increased risk of road traffic mortality, with the strongest association observed for compound heatwaves. The mortality burden attributable to compound heatwaves was higher than that for daytime and nighttime heatwaves. Heatwaves were more significantly associated with road traffic mortality risk among females, elderly individuals over 64 years old, and motor vehicle accidents.

Objective:To assess the association between temperature and risk of animal injury, and identifying vulnerable populations.Methods:Based on a time-stratified case-crossover design, the number of animal injuries monitored in hospitals of Guangdong Provincial Injury Surveillance System in 2011 and 2015-2016 was included, and the daily meteorological data were derived from the fifth generation of European ReAnalysis-Land, which was produced by the European Centre for Medium-Range Weather Forecasts. Conditional logistic regression combined with a distributed lagged nonlinear model was applied to analyze the association of temperature and animal-specific injuries. We also conducted stratified analysis by region, sex, age, occupation, and location of injury occurrence.Results:There was an almost linear relationship between temperature and the occurrence of animal injury. The excess risk ( ER) of animal injury was 2.65% (95% CI: 2.27%-3.04%) for a 1 ℃ rise in temperature with much higher risk of occurrence ( ER=9.34%, 95% CI: 7.57%-11.13%) for non-mammalian injury than that for mammalian injuries ( ER=2.30%, 95% CI: 1.90%-2.70%). Stratified analysis revealed that the occurrence of animal injury was more susceptible to temperature influences in urban ( ER=2.78%, 95% CI: 2.35%-3.21%), female ( ER=2.71%, 95% CI: 2.16%-3.27%), the elderly aged 60 years and above ( ER=3.05%, 95% CI: 1.65%- 4.47%), farmer ( ER=4.66%, 95% CI: 3.03%-6.32%) and agricultural area ( ER=10.63%, 95% CI: 7.57%-13.79%) than their correspondents. In terms of mammalian injury, dog bites showed the highest risk ( ER=2.71%, 95% CI: 2.12%-3.30%). In terms of non-mammalian,snake injuries were highly influenced by temperature ( ER=16.74%, 95% CI: 11.33%-22.40%). Conclusions:The ambient temperature rises could increase the risk of animal injury with much higher risk for non-mammalian than that for mammalian injuries. Our findings suggest that global warming may increase the risk and disease burden from animal injuries.
