BACKGROUND Acute myocardial infarction(AMI)is a severe cardiovascular disease caused by the blockage of coronary arteries that leads to ischemic necrosis of the myocardium.Timely medical contact is critical for successful AMI treatment,and delays increase the risk of death for patients.Pre-hospital delay time(PDT)is a significant challenge for reducing treatment times,as identifying high-risk patients with AMI remains difficult.This study aims to construct a risk prediction model to identify high-risk patients and develop targeted strategies for effective and prompt care,ultimately reducing PDT and improving treatment outcomes.AIM To construct a nomogram model for forecasting pre-hospital delay(PHD)likelihood in patients with AMI and to assess the precision of the nomogram model in predicting PHD risk.METHODS A retrospective cohort design was employed to investigate predictive factors for PHD in patients with AMI diagnosed between January 2022 and September 2022.The study included 252 patients,with 180 randomly assigned to the development group and the remaining 72 to the validation group in a 7:3 ratio.Independent risk factors influencing PHD were identified in the development group,leading to the establishment of a nomogram model for predicting PHD in patients with AMI.The model's predictive performance was evaluated using the receiver operating characteristic curve in both the development and validation groups.RESULTS Independent risk factors for PHD in patients with AMI included living alone,hyperlipidemia,age,diabetes mellitus,and digestive system diseases(P<0.05).A characteristic curve analysis indicated area under the receiver operating characteristic curve values of 0.787(95%confidence interval:0.716–0.858)and 0.770(95%confidence interval:0.660-0.879)in the development and validation groups,respectively,demonstrating the model's good discriminatory ability.The Hosmer–Lemeshow goodness-of-fit test revealed no statistically significant disparity between the anticipated and observed incidence of PHD in both development and validation cohorts(P>0.05),indicating satisfactory model calibration.CONCLUSION The nomogram model,developed with independent risk factors,accurately forecasts PHD likelihood in AMI individuals,enabling efficient identification of PHD risk in these patients. 展开更多

The immediate action taken at the site of the accident is crucial to the prognosis of the tooth. Replantation is considered as the treatment of choice. OBJECTIVE: The study was undertaken to assess the knowledge of parents who accompany their children to the pediatric dental clinic, KATH on the pre-hospital management of avulsed permanent tooth in children. METHODS: A researcher administered structured questionnaire was used to collect data on the knowledge of pre-hospital management of avulsed permanent tooth from 83 parents who accompanied their wards to the pediatric dental clinic at KATH. RESULTS: A total of 83 parents were involved in the study. 30 (36%) were males while 53 (64%) were females. The majority of the parents (57%) were either university trained or had attended college of education. Only 32 parents (39%) were aware of the possibility of replantation. Majority of the parents chose non-physiologic media as the transport media of choice and only 10% would attempt self-replantation before seeking professional help. 76 parents (92%) had no previous education on pre-hospital management of avulsed tooth. CONCLUSION: The results obtained from this study indicate that parental knowledge on pre-hospital management of avulsed permanent tooth is low hence the need for massive public educational campaigns. 展开更多

Tumor vaccines are a promising avenue in cancer immunotherapy.Despite the progress in targeting specific immune epitopes,tumor cells lacking these epitopes can evade the treatment.Here,we aimed to construct an efficient in situ tumor vaccine called Vac-SM,utilizing shikonin(SKN)to induce immunogenic cell death(ICD)and Mycobacterium smegmatis as an immune adjuvant to enhance in situ tumor vaccine efficacy.SKN showed a dose-dependent and time-dependent cytotoxic effect on the tumor cell line and induced ICD in tumor cells as evidenced by the CCK-8 assay and the detection of the expression of relevant indicators,respectively.Compared with the control group,the in situ Vac-SM injection in mouse subcutaneous metastatic tumors significantly inhibited tumor growth and distant tumor metastasis,while also improving survival rates.Mycobacterium smegmatis effectively induced maturation and activation of bone marrow-derived dendritic cells(DCs),and in vivo tumor-draining lymph nodes showed an increased maturation of DCs and a higher proportion of effector memory T-cell subsets with the Vac-SM treatment,based on flow cytometry analysis results.Collectively,the Vac-SM vaccine effectively induces ICD,improves antigen presentation by DCs,activates a specific systemic antitumor T-cell immune response,exhibits a favorable safety profile,and holds the promise for clinical translation for local tumor immunotherapy. 展开更多

Background Depressive symptoms and cognitive impairment often interact,rendering their associations controversial.To date,their joint trajectories and associations with dementia and death remain underexplored.Aims To explore the interactions between depressive symptoms and cognitive function,their developmental trajectories and the associations with all-cause dementia,Alzheimer’s disease(AD)and all-cause death in older adults.Methods Data were from the Health and Retirement Study.Depressive symptoms and cognitive function were measured using the 8-item Centre for Epidemiologic Studies Depression Scale and the Telephone Interview of Cognitive Status,respectively.All-cause dementia and AD were defined by self-reported or proxy-reported physician diagnoses.All-cause death was determined by interviews.The restricted cubic spline,group-based trajectory modelling and subdistribution hazard regression were used.Results Significant interactions between depressive symptoms and cognitive function in 2010 in their association with new-onset all-cause dementia and AD from 2010 to 2020 were found,especially in women(p for interaction<0.05).Independent trajectory analysis showed that emerging or high(vs no)depressive trajectories and poor or rapidly decreased cognitive trajectories(vs very good)from 1996 to 2010 were at significantly higher risk of subsequent all-cause dementia,AD and all-cause death.15 joint trajectories of depressive symptoms and cognitive function from 1996 to 2010 were determined,where rapidly decreased cognitive function was more common in those with no depressive symptoms.Compared with older adults with the trajectory of no depressive symptoms and very good cognitive function,those with the trajectory of no depressive symptoms but rapidly decreased cognitive function were much more likely to develop new-onset all-cause dementia and death,with subdistribution hazard ratios(95%confidence intervals)of 4.47(2.99 to 6.67)and 1.84(1.43 to 2.36),especially in women.Conclusions To effectively mitigate the risk of dementia and death,it is crucial to acknowledge the importance of preventing cognitive decline in older adults without depressive symptoms,particularly in women. 展开更多

Objective: Liver cancer is a major health concern globally and in China. This analysis investigated deaths and disability-adjusted life years(DALYs) with respect to etiologies and risk factors for liver cancer in China and worldwide.Methods: Global and China-specific data were collected on liver cancer deaths, DALYs, and age-standardized rates(ASRs) from the Global Burden of Disease Study 2019 database. Liver cancer etiologies were classified into five groups and risk factors were categorized into three levels. Each proportion of liver cancer burden was calculated in different geographic regions. The joinpoint regression model were used to assess the trends from 1990±2019.Results: Liver cancer accounted for 484,577 deaths worldwide in 2019 with an ASR of 5.9 per 100,000 population. China had an elevated liver cancer death ASR in 2019 and males had an ASR 1.7 times the global rate. The global ASR for DALYs peaked at 75±79 years of age but peaked earlier in China. Hepatitis B virus was the prominent etiology globally(39.5%) and in China(62.5%), followed by hepatitis C virus and alcohol consumption. In high sociodemographic index countries, non-alcoholic steatohepatitis has gained an increasing contribution as an etiologic factor. The liver cancer burden due to various etiologies has decreased globally in both genders. However, metabolic risk factors, particularly obesity, have had a growing contribution to the liver cancer burden, especially among males.Conclusions: Despite an overall decreasing trend in the liver cancer burden in China and worldwide, there has been a rising contribution from metabolic risk factors, highlighting the importance of implementing targeted prevention and control strategies that address regional and gender disparities. 展开更多

Introduction: Human immunodeficiency virus (HIV) is a major public health problem with high morbidity and mortality among children. The objective of this work was to audit the deaths of children and adolescents with HIV infection followed up in the pediatric department of the Regional Teaching Hospital of Borgou/Alibori (CHUDB/A) the from 2005 to 2020. Patients and Method: This was a retrospective and descriptive study conducted in the pediatric department of CHUD/B-A in Parakou. All children with HIV infection who died from January 1, 2005 to August 31, 2020 were included. Data collection was carried out in three stages: a phase of medical records processing, a phase of community survey and a phase of death audits. The variables studied were sociodemographic, clinical, biological, therapeutic and evolutionary. Results: Over the study period, the data of 464 infected children were recorded, including 92 deaths, representing a case fatality rate of 19.83%. Severe acute malnutrition (69.23%), gastro-intestinal tract infections (43.58%) and serious opportunistic pulmonary infections (24.36% pulmonary tuberculosis and 19.23% pneumocystis) were the main causes of death. The main dysfunctions found were: the delayed diagnosis of HIV infection (79.35%), the absence or delay in consultation when the child’s clinical condition deteriorates (32.61% and 47.83%), delayed initiation of antiretroviral treatment (42.39%) and non-adherence to treatment (38.04%). Non-adherence to treatment was predominant in adolescents (90.49%). Conclusion: Specific interventions for early detection, adequate nutritional care, psychosocial support for adolescents and mothers of children are necessary to reduce mortality due to HIV among children and adolescents. 展开更多

Introduction: The greatest effect of maternal mortality is renowned in children aged 2 - 5 months whose mothers had died. Children whose mothers died due to maternal complications were likely to record a higher mortality in infancy compared to children of surviving mothers. Motherless children mostly suffer a lot due to lack of day-to-day care, isolation, lack of motivation as well as economic cost associated with mother’s death. Thus, the purpose of this study was to ascertain the lives of children whose mothers passed away during childbirth at the Sagnarigu Municipality. Methods: This quantitative cross-sectional study was carried out at the Sagnarigu Municipal. The study recruited 297 respondents. To assess the effects of maternal death on the lives of children, families that experienced maternal death were assessed. The number of pregnancies experienced by the deceased woman, pregnancy-related complaints experienced, determinants of maternal death, number of children alive, and their standard of living were assessed with the aid of a structured questionnaire. Results: The data showed that negligence, illiteracy, poor road access, poverty, ignorance, delays in recognizing the problem, delays in making appropriate decisions, delays in the health facility, delays in giving the appropriate treatments, and traditional beliefs were some of the factors that led to maternal death in the Sagnarigu Municipality. Conclusion: The study concluded that determinants of maternal death in the Sagnarigu Municipal included the following;negligence, illiteracy, poverty, and delays in recognizing the problem. The study findings also demonstrated that the effects of maternal death on children are diverse and cut across different areas of a child’s life including livelihood sustenance, healthcare, education, and emotional and psychological development. 展开更多

Introduction: Stillbirths are estimated at 2 million each year, of which more than 40% occur during labour. Our objective was to study the epidemiological aspects of stillbirth and neonatal deaths in the delivery room in our health facility. Patients and methods: Prospective, descriptive and analytical study, conducted at the Jeanne Ebori Foundation Mother-Child University Hospital over 4 years (January 2019-December 2022). All neonatal deaths in the delivery room or foetal death in utero, were included. Results: Among the 18,346 deliveries performed, 512 newborns were declared dead in the delivery room (27.9‰ live births), divided into in utero foetal death (19.0‰) and immediate neonatal death (8.9‰). The mean age was 34.3 weeks of amenorrhea. The rate of preterm birth was 60.4%. The sex ratio was 1.1. The average weight was 2186.6. The main causes were vascular (46.1%), foetal (20.2%), adnexal (17.1%) and asphyxia per partum (16.6%). Foetal causes were more likely to result in IUFD than other causes (OR = 6.4 [2.4 - 15.7], p < 0.001). After birth, partum asphyxia was more likely to lead to death before 15 minutes of life than other causes (OR = 11 [6.1 - 18.9], p Conclusion: The causes of stillbirth and early neonatal mortality are dominated by maternal vascular pathologies. However, the proportion of childbirth-related causes remains worrying. Better monitoring of pregnancy and labour will minimize this prevalence in our hospital. 展开更多

Each year, approximately 1500 maternal deaths and more than 12,000 newborn deaths are recorded there. In order to correct the situation, strategies such as the implementation of Emergency Obstetric and Neonatal Care (EmONC) were initiated. Objective: Determine the rates of maternal deaths in EmONC centers in the Collines department from 2018 to 2022. Framework and Methods: The study took place in Benin precisely in the Collines department. This was a descriptive cross-sectional study. Data collection was carried out during the first two weeks of January 2023 and covered data from the 09 Basic Emergency Obstetric and Neonatal Care centers (BEMONC) and the Obstetric and Neonatal Care centers of Complete Emergency (CEmONC) of the Collines department from 2018 to 2022. An estimate of the ratios of maternal deaths occurring at the level of the EmONC centers of the Collines department from 2018-2022 was carried out followed by constructive suggestions. Results: During the five years (2018 to 2022), the Collines department recorded 42,582 live births with 148 maternal deaths, i.e. a ratio of 348 maternal deaths per 100,000 live births. Between 2018 and 2022, the highest maternal death ratio was recorded in 2019, i.e. 425 maternal deaths per 100,000 live births for all EmONC centers and 607 maternal deaths per 100,000 live births in EmONC centers. The highest maternal death ratio at the BEmONC center level was recorded in 2020, i.e. 129 maternal deaths per 100,000 births. Conclusion: These results suggest that despite the implementation of EmONC in the Collines department, maternal deaths have not decreased. To improve these outcomes for a reduction in maternal deaths, urgent action must be taken. 展开更多

The role of the autopsy: 1) Whether the death is ascribable to a natural or unnatural cause and when natural, if cardiac or extra-cardiac;2) The nosology of the cardiac diseases and the mechanism of cardiac death, whether arrhythmic or mechanical;3) If the cardiac disease is inherited, screening and counselling of the next of kin is required. About 30% of sudden deaths is ascribable to genetically determined morbid entities, mostly transmissible with the autosomal dominant pattern of inheritance, so that 50% of the first degree relatives are genetically affected (“carriers”) and exposed at risk;4) If toxic or illicit drug abuse was involved. 展开更多

Coronary artery anomaly is known as one of the causes of angina pectoris and sudden death and is an important clinical entity that cannot be overlooked.The incidence of coronary artery anomalies is as low as 1%-2%of the general population,even when the various types are combined.Coronary anomalies are practically challenging when the left and right coronary ostium are not found around their normal positions during coronary angiography with a catheter.If there is atherosclerotic stenosis of the coronary artery with an anomaly and percutaneous coronary intervention(PCI)is required,the suitability of the guiding catheter at the entrance and the adequate back up force of the guiding catheter are issues.The level of PCI risk itself should also be considered on a caseby-case basis.In this case,emission computed tomography in the R-1 subtype single coronary artery proved that ischemia occurred in an area where the coronary artery was not visible to the naked eye.Meticulous follow-up would be crucial,because sudden death may occur in single coronary arteries.To prevent atherosclerosis with full efforts is also important,as the authors indicated admirably. 展开更多

Background: Although maternal mortality is declining in most countries, it remains a significant public health problem worldwide, with high rates, particularly in developing and insecure countries like ours. Objective: To study the epidemiological factors and factors associated with the occurrence of maternal death in the Gynecology-Obstetrics Department of University Hospital of Tengandogo. Method: It was a retrospective case-control study with a descriptive and analytical purpose over a period of 6 years from January 1, 2017 to December 31, 2022. Cases were women with maternal deaths during the study period. Data processing and analysis were performed using Stata version 13 software. Univariate and multivariate analyses were performed with Stata version 13 software, and logistic regression modeling was used to estimate crude and adjusted odds ratios (OR), their 95% confidence intervals (CI), and the threshold for statistical significance was set at a p value < 0.05. Results: A total of 372 patients were included in the study, including 146 cases of maternal death. The in-hospital maternal mortality rate was 1933 deaths per 100,000 live births. The average age was 28.5 years. 58.9% of patients lived in rural areas. Married patients accounted for 88.7% of cases. The average parity was 3. Direct obstetrical causes were the main causes of death, accounting for 72.6%. They were dominated by post-partum hemorrhage (24.2%), puerperal infection (18.6%), pre-eclampsia/eclampsia (16.1%) and retroplacental hematoma (8.9%). Chronic anemia (12.9%) was the main indirect obstetric cause. Risk factors associated with maternal death were primiparity (OR for paucigravida and multigravida at 0.05;P = 0.001);ambulance transport (OR for patients referred and brought in by personal vehicle = 0.3, p < 0.001) and vaginal delivery (OR for cesarean deliveries = 0.4, p < 0.001). Conclusion: To reduce maternal mortality in Burkina Faso, strategies such as educating women about danger signs during pregnancy and promoting women’s education can be adopted. 展开更多
