    本研究旨在确定拉各斯艾滋病毒感染者(PLHIV)的灾难性医疗保健支出(CHE),并确定与CHE相关的因素。
    这项研究是在2021年1月至3月期间对来自拉各斯各种医疗机构的578名艾滋病毒携带者进行的描述性横断面调查,这些机构应免费提供艾滋病毒护理和治疗服务。通过预先测试的问卷收集数据,并使用StataSE12进行分析。
    每月平均食品支出为N29,282(53.2美元),而医疗保健支出平均为N8364(15.2美元)。近60%的受访者经历过CHE,而大约30%的人不得不借钱来支付他们的医疗费用。几乎所有人(96%)都没有健康保险计划。受访者\'组,个人收入,对当前健康状况的感知,家庭人数与灾难性卫生支出显著相关p<0.05。种族/少数族裔/移民组中的PLHIV和收入低于30,000($55)的人与CHE的统计学显着相关,p<0.001,OR分别为28.7和3.15。
    这项研究,因此,突出了PLHIV在获得医疗保健方面面临的广泛财务困难,以及政策加强金融风险保护的必要性。
    UNASSIGNED: This study aimed to determine the catastrophic healthcare expenditure (CHE) among people living with HIV (PLHIV) in Lagos and to identify factors associated with CHE among them.
    UNASSIGNED: The study was a descriptive cross-sectional survey conducted between January and March 2021 among 578 PLHIVs drawn from various healthcare facilities in Lagos where HIV care and treatment services should be provided free of charge. Data were collected through pretested questionnaires and analyzed using Stata SE 12.
    UNASSIGNED: The mean monthly expenditure on food was N29,282 ($53.2), while expenditure on healthcare averaged N8364 ($15.2). Nearly 60% of respondents experienced CHE, while around 30% had to borrow money to pay for some aspect of their medical treatment. Almost all (96%) had no health insurance plan. Respondents\' group, personal income, perception of current health status, and the number of people in their households were significantly associated with catastrophic health expenditure p < 0.05. PLHIV in the racial/ethnic minority/migrants\' group and those who earned less than ₦30,000 ($55) were statistically significantly associated with CHE at p < 0.001 with OR of 28.7 and 3.15, respectively.
    UNASSIGNED: The study, therefore, highlights the widespread financial hardship faced by PLHIV in accessing healthcare, and the need for policies to increase financial risk protection.

    事故和伤害在低收入和中等收入国家的死亡率和发病率中所占比例相当大。这会影响生产力最高的年龄组,并增加残疾调整寿命年(DALY)。这给家庭带来了巨大的经济负担。探讨事故和伤害对印度家庭的经济负担,并找出事故和伤害造成的灾难性健康支出(CHE)如何影响人口。另一个目标是探索印度家庭的灾难性自付支出(OOPE)模式和不良融资。
    该研究使用了第75轮全国代表性调查的数据,也就是说,全国抽样调查(NSS)。作者使用描述性二元logistic回归分析对数据进行了分析,以估计住院率和平均住院天数,平均OOPE,以及与公共和私人医疗机构分开的医疗支出遭受灾难性影响的人口比例。
    该研究观察到,私营部门的住院治疗使72%的家庭在超过10%的截止率下产生CHE,而41%的家庭在超过25%的截止率下产生CHE。相比之下,公共部门的情况较少,22%的家庭发生CHE超过家庭年人均收入的10%,9%超过25%。
    道路交通事故(RTA)的发生率不断增加,这是医疗系统过度紧张的问题。政府应提供更好的医疗设施和全民健康保险,以确保患者的早日康复和财务安全。
    UNASSIGNED: Accidents and injuries constitute a sizable share of mortality and morbidity in low- and middle-income countries. This affects the most productive age group and increases disability-adjusted life years (DALYs). It results in a substantial financial burden on the households. To explore the economic burden of accidents and Injuries on Indian households and to find how the catastrophic health expenditure (CHE) from accidents and injuries affects the population. Another objective is to explore Catastrophic out-of-pocket expenditures (OOPE) patterns and distressed financing of households in India.
    UNASSIGNED: The study used data from the 75th round of nationally representative surveys, that is, the National Sample Survey (NSS). Authors have analyzed the data using descriptive binary logistic regression analysis to estimate the rate and average days of hospitalization, average OOPE, and share of the population experiencing the catastrophic impact from the health expenditure separately from the public and private healthcare institutions.
    UNASSIGNED: The study observed that hospitalization in the private sector imposes 72% of households incur CHE at more than 10% cut-off and 41% at more than 25% cut-off. In comparison, it is less in the public sector, with 22% of households incurring CHE at more than 10% of annual per capita household income and 9% at more than 25%.
    UNASSIGNED: The increasing incidence of road traffic accidents (RTA) is a concern for the overstretched health system. The government should provide better healthcare facilities and universal health insurance coverage to ensure patients\' speedy recovery and financial security.

    癌症护理在印度造成了巨大的经济负担,非传染性疾病导致大量死亡和残疾调整寿命年。尽管经济增长,公平的财富分配仍然是一个挑战,导致医疗服务的不平等。印度的医疗体系主要是私有化的,通过自费支出(OOPE)供资,并且缺乏对大多数人口的覆盖。因此,没有经济能力的个人在寻求必要的医疗保健时会面临灾难性的健康后果。OOPE在印度的医疗保健系统是一个主要问题,药品占费用的很大一部分,其次是诊断测试和咨询费。非医疗费用也造成了经济负担。癌症护理特别面临巨大的财务挑战,治疗费用高,减少劳动力参与,以及困境融资的必要性。癌症相关的OOPE主要由患者及其家人承担,导致巨大的财务压力。缺乏全面的医疗保险和获得公共资助的医疗保健服务的机会有限,加剧了这一问题。癌症护理中的灾难性健康支出(CHE)很普遍,使家庭陷入财务困境和潜在的贫困。已经努力解决这个问题,例如增加医疗保健方面的公共支出和实施健康保险计划。然而,在确保其有效性和影响力方面仍然存在挑战。在与癌症相关的姑息治疗相关的灾难性健康支出期间,家庭护理医生的作用对于支持患者及其家人至关重要。他们协调护理,提供宣传,情感支持,症状管理,并促进临终讨论。需要采取综合措施来加强医疗基础设施,改善获得负担得起的癌症治疗,扩大医疗保险覆盖面,并对癌症患者实施支持措施。此外,促进预防措施和早期发现可以帮助减少对昂贵治疗的需求,并降低灾难性卫生支出的风险。
    Cancer care poses a significant economic burden in India, where noncommunicable diseases contribute to a large number of deaths and disability-adjusted life-years. Despite economic growth, equitable wealth distribution remains a challenge, leading to inequalities in healthcare access. India\'s healthcare system is primarily privatized, financed through out-of-pocket expenditure (OOPE), and lacks coverage for a majority of the population. As a result, individuals without financial means face catastrophic health consequences when seeking necessary healthcare. OOPE in India\'s healthcare system is a major concern, with medicines accounting for a significant portion of expenses, followed by diagnostic tests and consultation fees. Nonmedical expenses also contribute to the financial burden. Cancer care specifically faces substantial financial challenges, with high treatment costs, reduced workforce participation, and the need for distress financing. Cancer-related OOPE is predominantly borne by patients and their families, leading to significant financial strain. The lack of comprehensive health insurance coverage and limited access to publicly funded healthcare services exacerbate the problem. Catastrophic health expenditure (CHE) in cancer care is prevalent, pushing households into financial distress and potentially impoverishment. Efforts have been made to address this issue, such as increasing public spending on healthcare and implementing health insurance schemes. However, challenges remain in ensuring their effectiveness and reach. The role of family care physicians is crucial in supporting patients and their families during catastrophic health expenditures related to cancer-related palliative care. They coordinate care, provide advocacy, emotional support, symptom management, and facilitate end-of-life discussions. Comprehensive measures are needed to strengthen healthcare infrastructure, improve access to affordable cancer care, enhance health insurance coverage, and implement supportive measures for cancer patients. Additionally, promoting preventive measures and early detection can help reduce the need for expensive treatments and decrease the risk of catastrophic health expenditures.

    阿尔茨海默病(AD)是最常见的痴呆形式。它增加了其他严重疾病的风险,并对个人造成巨大影响,家庭,和社会经济学。AD是一种复杂的多因素疾病,目前的药物治疗主要基于抑制与AD发病机制有关的酶。天然酶抑制剂是靶向AD治疗的潜在来源,主要来自植物,海洋生物,或微生物。特别是,与其他来源相比,微生物来源具有许多优势。虽然已经报道了一些关于AD的评论,这些以前的评论大多集中在介绍和讨论AD的一般理论或概述各种来源的酶抑制剂,如化学合成,植物,和海洋生物,而关于抗AD酶抑制剂的微生物来源只有很少的评论。目前,多靶向药物研究是AD潜在治疗的新趋势。然而,没有综述从微生物来源全面讨论了各种酶抑制剂。这篇综述广泛地解决了上述方面,同时更新了并提供了有关AD发病机理中涉及的酶靶标的更全面的观点。本文还涵盖了使用计算机研究从微生物中发现有关AD抑制剂的药物的新兴趋势以及进一步实验研究的观点。
    Alzheimer\'s disease (AD) is the most common form of dementia. It increases the risk of other serious diseases and causes a huge impact on individuals, families, and socioeconomics. AD is a complex multifactorial disease, and current pharmacological therapies are largely based on the inhibition of enzymes involved in the pathogenesis of AD. Natural enzyme inhibitors are the potential sources for targeting AD treatment and are mainly collected from plants, marine organisms, or microorganisms. In particular, microbial sources have many advantages compared to other sources. While several reviews on AD have been reported, most of these previous reviews focused on presenting and discussing the general theory of AD or overviewing enzyme inhibitors from various sources, such as chemical synthesis, plants, and marine organisms, while only a few reviews regarding microbial sources of enzyme inhibitors against AD are available. Currently, multi-targeted drug investigation is a new trend for the potential treatment of AD. However, there is no review that has comprehensively discussed the various kinds of enzyme inhibitors from the microbial source. This review extensively addresses the above-mentioned aspect and simultaneously updates and provides a more comprehensive view of the enzyme targets involved in the pathogenesis of AD. The emerging trend of using in silico studies to discover drugs concerning AD inhibitors from microorganisms and perspectives for further experimental studies are also covered here.

    未经证实:缺乏促进肝硬化患者隐性肝性脑病(CHE)诊断的血液生物标志物。星形胶质细胞肿胀是肝性脑病的主要组成部分。因此,我们假设胶质纤维酸性蛋白(GFAP),星形胶质细胞的主要中间细丝,可能有助于早期诊断和管理。本研究旨在探讨血清GFAP(sGFAP)水平作为CHE生物标志物的实用性。
    未经评估:在这项双中心研究中,135例肝硬化患者,21名患有持续有害饮酒和肝硬化的患者,招募了15名健康对照。使用心理测量学肝性脑病评分诊断CHE。使用高度敏感的单分子阵列(SiMoA)免疫测定来测量sGFAP水平。
    未经批准:总共,50人(37%)在纳入研究时出现CHE。有CHE的参与者显示sGFAP水平显著高于没有CHE的参与者(sGFAP中位数,163pg/ml[IQR136;268]vs.106pg/ml[IQR75;153];p<0.001)或健康对照(p<0.001)。sGFAP与心理测量学肝性脑病评分结果相关(Spearman’sρ=-0.326,p<0.001),终末期肝病评分模型(Spearman’sρ=0.253,p=0.003),氨(斯皮尔曼的ρ=0.453,p=0.002),和IL-6血清水平(斯皮尔曼ρ=0.323,p=0.006)。此外,在多变量逻辑回归分析中,sGFAP水平与CHE的存在独立相关(比值比1.009;95%CI1.004-1.015;p<0.001)。酒精相关性肝硬化患者的sGFAP水平与非酒精相关性肝硬化患者或持续饮酒患者与停止饮酒的患者。结论:sGFAP水平与肝硬化患者CHE相关。这些结果表明,星形胶质细胞损伤可能已经发生在肝硬化和亚临床认知缺陷的患者中,并且sGFAP可以作为一种新的生物标志物进行探索。
    未经证实:缺乏促进肝硬化患者隐性肝性脑病(CHE)诊断的血液生物标志物。在这项研究中,我们能够证明sGFAP水平与肝硬化患者的CHE相关.这些结果表明,星形胶质细胞损伤可能已经发生在肝硬化和亚临床认知缺陷的患者中,并且sGFAP可以作为一种新的生物标志物进行探索。
    UNASSIGNED: Blood biomarkers facilitating the diagnosis of covert hepatic encephalopathy (CHE) in patients with cirrhosis are lacking. Astrocyte swelling is a major component of hepatic encephalopathy. Thus, we hypothesised that glial fibrillary acidic protein (GFAP), the major intermediate filament of astrocytes, might facilitate early diagnosis and management. This study aimed to investigate the utility of serum GFAP (sGFAP) levels as a biomarker of CHE.
    UNASSIGNED: In this bicentric study, 135 patients with cirrhosis, 21 patients with ongoing harmful alcohol use and cirrhosis, and 15 healthy controls were recruited. CHE was diagnosed using psychometric hepatic encephalopathy score. sGFAP levels were measured using a highly sensitive single-molecule array (SiMoA) immunoassay.
    UNASSIGNED: In total, 50 (37%) people presented with CHE at study inclusion. Participants with CHE displayed significantly higher sGFAP levels than those without CHE (median sGFAP, 163 pg/ml [IQR 136; 268] vs. 106 pg/ml [IQR 75; 153]; p <0.001) or healthy controls (p <0.001). sGFAP correlated with results in psychometric hepatic encephalopathy score (Spearman\'s ρ = -0.326, p <0.001), model for end-stage liver disease score (Spearman\'s ρ = 0.253, p = 0.003), ammonia (Spearman\'s ρ = 0.453, p = 0.002), and IL-6 serum levels (Spearman\'s ρ = 0.323, p = 0.006). Additionally, sGFAP levels were independently associated with the presence of CHE in multivariable logistic regression analysis (odds ratio 1.009; 95% CI 1.004-1.015; p <0.001). sGFAP levels did not differ between patients with alcohol-related cirrhosis vs. patients with non-alcohol-related cirrhosis or between patients with ongoing alcohol use vs. patients with discontinued alcohol use.Conclusions: sGFAP levels are associated with CHE in patients with cirrhosis. These results suggest that astrocyte injury may already occur in patients with cirrhosis and subclinical cognitive deficits and that sGFAP could be explored as a novel biomarker.

    本文定义了“多维健康贫困”的概念,“考虑到健康贫困的货币方面和多维健康剥夺。此外,通过修正传统的A-FMPI方法,建立多维健康贫困指数(MHPI),具体来说,我们将灾难性卫生支出(CHE)作为充分条件,将收入贫困作为必要条件,并采取物理,心理,和社会健康考虑在内。测量结果证明身体健康,货币层面(CHE和收入贫困),在中国,心理健康对健康贫困的贡献最大。此外,农村地区的MHPI明显高于城市地区,因为自付医疗费用较高,而且在更多方面缺乏健康。与传统方法相比,MHPI更准确,稳定,全面,使其更适合衡量健康贫困。
    This article defines the concept of \"multidimensional health poverty,\" considering both the monetary aspects and multidimensional health deprivation of health poverty. Moreover, we set up the multidimensional health poverty index (MHPI) to measure health poverty in China by revising the traditional A-F MPI method, specifically we use the Catastrophic Health Expenditure (CHE) as a sufficient condition and income poverty as a necessary condition, and take physical, mental, and social health into account. The measurement result evidences that physical health, monetary dimensions (CHE and income poverty), and mental health contribute most to health poverty in China. In addition, the MHPI is significantly higher in rural areas than urban because of higher out-of-pocket medical payments and health deprivation in more dimensions. Compared with the traditional method, the MHPI is more accurate, stable, and comprehensive, making it more suitable for measuring health poverty.

    China has built a social medical insurance system that covers the entire population so as to reduce the impact of diseases on individuals and families. Although the decline in the incidence of catastrophic health expenditures (CHEs) in China is encouraging, this issue remains important. On the basis of considering selectivity bias and heterogeneity, we applied propensity score matching (PSM) to analyze the 2018 data from the China Family Panel Studies. We assigned CHE households and non-CHE households to the treatment group and the control group, respectively, and used non-random data to simulate a randomized trial to investigate the impact of CHE on household consumption in China. The results of this study indicate that, when the threshold is set at 40%, the consumption of households experiencing CHEs (CHE household) is significantly lower than that of households not experiencing CHEs (non-CHE households) and that CHEs have a significant negative impact on other household consumption and a significant impact on the household property and debt. This effect still exists when the threshold is set lower, with household essential consumption most affected. The occurrence of CHEs leads to a reduction in household consumption and a significantly worsening financial situation for the CHE households, impacting the basic quality of life of the families. Therefore, it is necessary to further reform the medical and health system to reduce the high medical expenses.

    铝(Al)是环境中普遍存在的矿物元素。大脑是铝毒性的中心目标,极易受到氧化损伤。因此,识别防止Al介导的神经元细胞死亡的药物或天然产物是预防和治疗神经退行性疾病的有力策略。这项工作的目的是探索从哈里夏叶提取物调节神经行为的潜力,Al在体内实验诱导的生化和组织病理学活性。接受Al处理的大鼠在被动回避测试中表现出学习和记忆能力的降低,除了抑制Bcl2表达外,海马单胺和谷氨酸水平也降低。此外,丙二醛(MDA),炎症标志物(TNF-α,IL-1β),凋亡标志物(caspase-3和Bax的表达)和细胞外调节激酶(ERK1/2)水平与乙酰胆碱酯酶(AChE)活性一起升高,在Al处理的动物中观察到脑组织海马区中淀粉样蛋白β斑块的组织学变化和明显沉积。同时给予高剂量的深渊H.abyssinica(200mg/kgb.w.)恢复了几乎正常水平的所有测量参数,而不是低剂量(100mg/kgb.w.),与参考药物(卡巴拉汀)相当的效果。分子对接揭示了提取物组分阻断AChE和ERK2活性位点的适当潜力。总之,H.苦参素叶提取物赋予神经保护以抵抗铝诱导的神经毒性作用,最有可能是由于其高的酚类和类黄酮含量。
    Aluminum (Al) is an omnipresent mineral element in the environment. The brain is a central target of Al toxicity, being highly susceptible to oxidative damage. Therefore, recognition of drugs or natural products that guard against Al-mediated neuronal cell death is a powerful strategy for prevention and treatment of neurodegenerative disorders. This work aimed to explore the potential of a leaf extract from Harrisonia abyssinica to modulate the neurobehavioral, biochemical and histopathological activities induced experimentally by Al in vivo. Rats subjected to Al treatment displayed a reduction in learning and memory performance in a passive avoidance test accompanied by a decrease in the hippocampal monoamine and glutamate levels in addition to suppression of Bcl2 expression. Moreover, malondialdehyde (MDA), inflammatory markers (TNF-α, IL-1β), apoptotic markers (caspase-3 and expression of Bax) and extracellular regulated kinase (ERK1/2) levels were elevated along with acetylcholinesterase (AChE) activity, histological changes and marked deposition of amyloid β plaques in the hippocampus region of the brain tissues being observed in Al-treated animals. Concomitant administration of the high dose of H. abyssinica (200 mg/kg b.w.) restored nearly normal levels of all parameters measured, rather than the low dose (100 mg/kg b.w.), an effect that was comparable to the reference drug (rivastigmine). Molecular docking revealed the appropriate potential of the extract components to block the active site of AChE and ERK2. In conclusion, H. abyssinica leaf extract conferred neuroprotection against Al-induced neurotoxic effects, most likely due to its high phenolic and flavonoid content.
