    Viral infections are known as one of the major factors causing death. Ginseng is a medicinal plant that demonstrated a wide range of antiviral potential, and saponins are the major bioactive ingredients in the genus Panax with vast therapeutic potential. Studies focusing on the antiviral activity of the genus Panax plant-derived agents (extracts and saponins) and their mechanisms were identified and summarized, including contributions mainly from January 2016 until January 2022. P. ginseng, P. notoginseng, and P. quinquefolius were included in the review as valuable medicinal herbs against infections with 14 types of viruses. Reports from 9 extracts and 12 bioactive saponins were included, with 6 types of protopanaxadiol (PPD) ginsenosides and 6 types of protopanaxatriol (PPT) ginsenosides. The mechanisms mainly involved the inhibition of viral attachment and replication, the modulation of immune response by regulating signaling pathways, including the Janus kinase (JAK)/signal transducer and activator of transcription (STAT) pathway, cystathionine γ-lyase (CSE)/hydrogen sulfide (H2S) pathway, phosphoinositide-dependent kinase-1 (PDK1)/ protein kinase B (Akt) signaling pathway, c-Jun N-terminal kinase (JNK)/activator protein-1 (AP-1) pathway, and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) pathway. This review includes detailed information about the mentioned antiviral effects of the genus Panax extracts and saponins in vitro and in vivo, and in human clinical trials, which provides a scientific basis for ginseng as an adjunctive therapeutic drug or nutraceutical.

    UNASSIGNED:在慢性乙型肝炎患者中停止核苷(酸)类似物(NUCs)后严重临床结果的风险仍然不明确。本系统综述和荟萃分析旨在评估有关此问题的现有文献。
    未经授权:我们搜索了PubMed,Embase,和WebofScienceforNUC停止研究,注意到2006年1月1日至2022年8月18日发表的临床结果。我们进行了荟萃研究分析,以检查报告的结果与研究设计和特征的关系,并与非重叠人群进行了汇总研究,以提供(1)严重肝炎耀斑或肝功能失代偿或(2)肝炎耀斑相关死亡或肝移植的比例的风险估计。
    UNASSIGNED:荟萃研究分析包括50项高度异质性设计和特征的研究。我们发现,根据结果定义,安全性结果的报告差异很大,随访持续时间,和样本量。只有10项研究预先指定的安全事件作为研究结果,只有四个人的结局定义包括肝功能不全,随访时间>12个月,样本量>100名患者。我们进一步汇集了15项研究,包括4,525名个体,估计1.21%(95%CI0.70-2.08%)会发生严重的肝炎耀斑或失代偿。具有显著的异质性(I2=54%,p<0.01),而肝炎相关死亡或肝移植将发生在0.37%(95%CI0.20-0.67%),无明显异质性(I2=0.00%,p=1.00)。
    UNASSIGNED:目前关于NUC停止后严重临床结局风险的文献非常有限且高度异质性。对现有数据的汇总分析发现,停止NUCs的患者中约有1%出现严重的耀斑或肝功能失代偿。
    UNASSIGNED:目前有关NUC停止治疗慢性乙型肝炎患者的安全性问题的文献在设计和特征上是有限和异质的,因此,应该非常谨慎地解释。根据现有数据,发生严重肝炎耀斑或肝功能失代偿的患者比例估计为1.21%,耀斑相关死亡或肝移植的患者比例估计为0.37%.我们的发现对于接受核苷(t)ide类似物用于乙型肝炎病毒感染的个体非常重要,因为我们不仅汇集了当前可用的数据来估计停止治疗后严重临床不良事件的风险,而且还揭示了现有文献关于有限治疗安全性的关键限制。
    UNASSIGNED: The risk of serious clinical outcomes following cessation of nucleos(t)ide analogues (NUCs) in individuals with chronic hepatitis B remains poorly characterized. This systematic review and meta-analysis aimed to evaluate current literature on this issue.
    UNASSIGNED: We searched PubMed, Embase, and Web of Science for NUC stop studies that noted clinical outcomes published between January 1, 2006 and August 18, 2022. We performed meta-research analyses to examine the relationships of reported outcomes with study designs and characteristics and also pooled studies with non-overlapping populations to provide risk estimates for the proportions of (1) severe hepatitis flares or hepatic decompensation or (2) hepatitis flare-related death or liver transplantation.
    UNASSIGNED: The meta-research analysis included 50 studies of highly heterogeneous designs and characteristics. We found that reporting of safety outcomes varied widely according to outcome definition, follow-up duration, and sample size. Only ten studies prespecified safety events as the study outcome, and only four had an outcome definition to include hepatic insufficiency, a follow-up duration >12 months, and a sample size >100 patients. We further pooled 15 studies with 4,525 individuals and estimated that severe hepatitis flares or decompensation would occur in 1.21% (95% CI 0.70-2.08%), with significant heterogeneity (I 2 = 54%, p <0.01), while hepatitis flare-related death or liver transplantation would occur in 0.37% (95% CI 0.20-0.67%), without significant heterogeneity (I 2 = 0.00%, p = 1.00).
    UNASSIGNED: Current literature on the risk of serious clinical outcomes following NUC cessation is very limited and highly heterogeneous. Pooled analyses of available data found approximately 1% of patients who stopped NUCs developed severe flares or hepatic decompensation.
    UNASSIGNED: Current literature regarding the safety concerns surrounding NUC cessation for individuals with chronic hepatitis B is limited and heterogeneous in designs and characteristics, and thus should be interpreted with great caution. Based on currently available data, the proportion of patients that develop severe hepatitis flares or hepatic decompensation was estimated at 1.21% and that of flare-related death or liver transplantation at 0.37%. Our findings are important for individuals receiving nucleos(t)ide analogues for hepatitis B virus infection because we not only pooled currently available data to estimate the risk of serious clinical adverse events following treatment cessation but also uncovered critical limitations of existing literature regarding the safety of finite therapy.

    怀孕期间的乙型肝炎病毒(HBV)感染与围产期传播有关,从而导致人群中的HBV感染池。来自印度各地的孕妇HBV血清阳性率的报告数据差异很大。因此,我们进行了系统评价和荟萃分析,以确定HBV的合并血清阳性率及其相关的人口统计学因素.
    Medline的全面文献检索,Scopus,GoogleScholar于2000年1月至2022年4月进行了研究,以评估印度孕妇中HBV的患病率。
    共有44项研究纳入了有关272,595名患者的数据。乙型肝炎表面抗原(HBsAg)的孕妇合并患病率为1.6%[95%置信区间(CI),1.4-1.8]。在HBsAg阳性患者中,乙型肝炎e抗原的合并患病率为26.0%(95CI17.4-34.7).基于年龄的HBV血清阳性率的几率没有显着差异(<25岁与>25年)[赔率比(OR)1.07,95CI0.74-1.55],奇偶校验(初值vs.多段)(OR1.09,95CI0.70-1.70)或居住面积(城市与农村)(OR0.88,95CI0.56-1.39)。然而,未受过教育或初等教育的患者的HBV血清阳性率高于受过中等教育或以上教育的患者(OR2.29,95CI1.24-4.23).13.5-22.7%的患者存在风险因素的既往史,表明垂直获取模式。
    在印度,孕妇中HBV的流行率很低。在不到25%的病例中发现了风险因素,表示垂直传输是主要的采集模式,这可以通过提高疫苗接种覆盖率来减少。
    UNASSIGNED: Hepatitis B virus (HBV) infection during pregnancy is associated with perinatal transmission contributing to the pool of HBV infection in the population. There is a wide variation in the reported data on the seroprevalence of HBV in pregnant patients from various parts of India. Hence, a systematic review and meta-analysis was conducted to determine the pooled seroprevalence of HBV and its associated demographic factors.
    UNASSIGNED: A comprehensive literature search of Medline, Scopus, and Google Scholar was conducted from January 2000 to April 2022 for studies evaluating the prevalence of HBV in pregnant patients from India.
    UNASSIGNED: A total of 44 studies with data on 272,595 patients were included in the meta-analysis. The pooled prevalence of hepatitis B surface antigen (HBsAg) in pregnant women was 1.6% [95% confidence interval (CI), 1.4-1.8]. Among patients with HBsAg positivity, the pooled prevalence of hepatitis B e antigen was 26.0% (95%CI 17.4-34.7). There was no significant difference in the odds of HBV seroprevalence based on the age (<25 years vs. > 25 years) [odds ratio (OR) 1.07, 95%CI 0.74-1.55], parity (primipara vs. multipara) (OR 1.09, 95%CI 0.70-1.70) or area of residence (urban vs. rural) (OR 0.88, 95%CI 0.56-1.39). However, the odds of HBV seroprevalence in those with no or primary education was higher than in those with secondary level education or higher (OR 2.29, 95%CI 1.24-4.23). Prior history of risk factors was present in 13.5-22.7% of patients indicating a vertical mode of acquisition.
    UNASSIGNED: There is a low endemicity of HBV among pregnant women in India. Risk factors are seen in less than 25% of the cases, indicating vertical transmission as the predominant mode of acquisition, which can be reduced by improving vaccination coverage.

    肝硬化患者的密切随访导致早期肝细胞癌(HCC)的检测增加,尤其是磁共振成像(MRI)创新。我们报道了一个70岁男子的病例,由于慢性丙型肝炎病毒(HCV)并发肝细胞癌(HCC),最近有肝硬化史,计划对其进行肝动脉化疗栓塞(TACE),因为患者在入院时被分配为儿童B7。在第一个TACE周期中进行的血管造影不仅显示与先前检测到的HCC相对应的“肿瘤腮红”,而且在大的增生性结节中看到的HCC摄取的其他小病灶,从而出现“结节内结节”。“早期发现肝细胞癌可以改善预后。因此,了解HCC的所有早期方面至关重要,包括横断面成像上结节内结节的外观,在血管造影中,在这种情况下。
    Close follow-up of patients with liver cirrhosis has led to increased detection of hepatocellular carcinoma (HCC) at an early stage, especially with magnetic resonance imaging (MRI) innovations. We report the case of a 70-year-old man, with a recent history of liver cirrhosis due to chronic hepatitis C virus (HCV) complicated by hepatocellular carcinoma (HCC), and for whom trans-arterial chemoembolization (TACE) was planned, as the patient was assigned Child B7 at admission. Angiography performed during the first TACE cycle shows not only the \"tumor blush\" corresponding to previously detected HCC but also an additional small foci of HCC uptake seen within a large dysplastic nodule giving the appearance of \"nodule-within-nodule.\" Early detection of hepatocellular carcinoma improves prognosis. Hence, it is essential to be aware of all early aspects of HCC, including the nodule-within-nodule appearance on cross-sectional imaging, and also in angiography, as in this case.

    肝内胆管癌(iCCA)通常是一种致命的恶性肿瘤,在全球范围内发病率上升。手术切除目前仍然是唯一的治愈性治疗。然而,因为只有少数iCCA适合切除,需要新的治疗方式。我们的目的是对现有的关于iCCA使用消融疗法的文献进行系统回顾和荟萃分析,并通过计算合并的生存结果来评估其作为治疗方式的疗效,并研究预后因素与生存之间的关系。
    对PubMed数据库进行了相关文章的全面搜索。包括评估接受消融的iCCA患者生存率的研究。提取了患者的数据,肿瘤和治疗特征和存活率。随机效应荟萃分析用于汇总数据。使用Galbraith图研究异质性;使用基于回归的荟萃分析制定气泡图。
    共有10项研究纳入最终分析,共产生206名患者(69.5%为男性,中位年龄:51.2-72.5)和320个肿瘤。在所有患者中,70.4%为iCCA复发病例,原发性iCCA占29.6%。中位总生存期为8.7至52.4个月。汇集1-,3年和5年生存率为76%(95%置信区间:68-83%),33%(21-44%)和16%(7-26%),分别。中位年龄之间没有发现显着关联,肿瘤数量或中位肿瘤大小和1年生存率。
    消融疗法作为iCCA的治疗方式显示出有希望的潜力。然而,需要进一步的研究来验证这些发现。
    UNASSIGNED: Intrahepatic cholangiocarcinoma (iCCA) is usually a fatal malignancy with rising incidence globally. Surgical resection currently remains the only curative treatment. However, as only a minority of iCCA is amenable to resection, new therapeutic modalities are needed. Our aims were to systematically review and perform a meta-analysis on the existing literature regarding the use of ablative therapies for iCCA and to assess their efficacy as a treatment modality by calculating pooled survival results and investigate associations between prognostic factors and survival.
    UNASSIGNED: A comprehensive search of the PubMed database for relevant articles was performed. Studies assessing survival in patients with iCCA undergoing ablation were included. Data were extracted on patient, tumour and treatment characteristics and survival. Random effects meta-analysis was used to pool the data. Galbraith plots were used to investigate heterogeneity; bubble plots were formulated using regression-based meta-analysis.
    UNASSIGNED: A total of 10 studies were included in the final analysis, yielding an aggregate of 206 patients (69.5% males, median age: 51.2-72.5) and 320 tumours. Of all patients, 70.4% were recurrent cases of iCCA, and 29.6% were cases of primary iCCA. The median overall survival ranged from 8.7 to 52.4 months. Pooled 1-, 3- and 5-year survival rates were 76% (95% confidence interval: 68-83%), 33% (21-44%) and 16% (7-26%), respectively. No significant association was found between the median age, number of tumours or median tumour size and 1-year survival.
    UNASSIGNED: Ablative therapies display promising potential as treatment modalities for iCCA. However, further research is necessary to validate these findings.

    全球每年约有700,000人死于肝细胞癌(HCC)。使其成为癌症相关死亡的第三大原因。破裂是HCC的潜在威胁生命的并发症。肝癌破裂在亚洲和非洲的发病率高于欧洲。在亚洲,每年约有10%的诊断为HCC的患者因破裂而死亡。自发性破裂是继肿瘤进展和肝功能衰竭之后,肝癌死亡的第三大常见原因。在没有肝硬化或HCC病史的患者中诊断破裂可能很困难。肝癌破裂最常见的症状是腹痛(66-100%)。在33-90%的病例中可以看到出现休克;据报道,腹胀占33%。腹腔穿刺术记录腹膜积血是暂时诊断HCC破裂的可靠测试,它可以在高达86%的临床疑似病例中看到。诊断可以通过计算机断层扫描或超声检查来确认,或者在75%的病例中两者兼而有之。仔细的治疗前评估对于决定最佳治疗方案至关重要。破裂HCC的管理涉及多学科护理,止血仍然是主要问题。较早的研究报告说,肝癌破裂急性期的死亡率为25-75%。然而,最近的研究报告了死亡率的显著下降。由于HCC的监测和早期检测的改善,HCC破裂的发生率也有所下降。经动脉栓塞是在急性期有效诱导止血的侵入性最小的方法,成功率为53-100%。另一方面,肝切除术具有实现止血的优势,并且在相同的过程中在选定的患者中提供了潜在的治愈性切除术。
    Approximately 700,000 people die of Hepatocellular Carcinoma (HCC) each year worldwide, making it the third leading cause of cancer related deaths. Rupture is a potentially life-threatening complication of HCC. The incidence of HCC rupture is higher in Asia and Africa than in Europe. In Asia approximately 10% of patients with a diagnosis of HCC die due to rupture each year. Spontaneous rupture is the third most common cause of death due to HCC after tumor progression and liver failure. The diagnosis of rupture in patients without history of cirrhosis or HCC may be difficult. The most common symptom of ruptured HCC is abdominal pain (66-100%). Shock at presentation can be seen in 33-90% of cases; abdominal distension is reported in 33%. Abdominal paracentesis documenting hemoperitoneum is a reliable test to provisionally diagnose rupture of HCC, it can be seen in up to 86% of clinically suspected cases. The diagnoses can be confirmed by computed tomography scan or ultrasonography, or both in 75% of cases. Careful pre-treatment evaluation is essential to decide the best treatment option. Management of ruptured HCC involves multi-disciplinary care where hemostasis remains a primary concern. Earlier studies have reported a mortality rate of 25-75% in the acute phase of ruptured HCC. However, recent studies have reported a significant decrease in the incidence of mortality. There is also a decrease in the incidence of ruptured HCC due to improved surveillance and early detection of HCC. Transarterial Embolization is the least invasive method to effectively induce hemostasis in the acute stage with a success rate of 53-100%. Hepatic resection in the other hand has the advantage of achieving hemostasis and in the same go offers a potentially curative resection in selected patients.

    Kidney disease is an important extra-hepatic manifestation of hepatitis B virus (HBV) infection. However, there is paucity of recent literature on kidney disease in children and adolescents with HBV infection from several parts of sub-Saharan Africa including Nigeria.
    To review the pattern of kidney disease in hepatitis B surface antigen (HBsAg)-positive children and adolescents seen at a tertiary hospital in south-west Nigeria.
    A retrospective study was undertaken of HBsAg-seropositive children with kidney disease managed at University College Hospital, Ibadan, from January 2004 to December 2015. Patients were identified from the paediatric nephrology unit admissions and the renal histology registers.
    24 children and adolescents were studied, 17 of whom were male (70.8%), and the median age was 10.0 years (range 3-15). Ten (41.7%) had nephrotic syndrome, five (20.8%) had non-nephrotic glomerulonephritis, five (20.8%) were in end-stage renal disease (ESRD), including a patient with posterior urethral valves, and four had acute kidney injury secondary to acute tubular necrosis. Renal histology was available for 10 patients: nine had nephrotic syndrome associated with minimal change disease in six, focal segmental glomerulosclerosis in two and one had membanoproliferative glomerulonephritis. The patient with non-nephrotic glomerulonephritis had diffuse global sclerosis.
    The pattern of kidney disease in HBV-positive children demonstrated a predominance of nephrotic syndrome, followed by non-nephrotic glomerulonephritis, ESRD and acute kidney injury. Better diagnostic facilities and treatment are required. Prevention of HBV infection by universal childhood immunisation is the ultimate goal.

    在过去的几十年里,随着外科技术的标准化和进步,免疫抑制和肝移植后患者护理,优化了肝移植的结局。然而,移植的主要限制仍然是获得同种异体移植物。可以从肝移植中受益的患者数量明显超过了可用的已故供体数量。越来越多的等待肝移植的患者与供体器官的稀缺性之间的巨大差距推动了最大化现有供体库并确定新的途径的努力。本文回顾了使用扩展标准供体(老年供体,脂肪捐赠者,有恶性肿瘤的捐赠者,病毒性肝炎的捐赠者),心脏死亡后的捐赠,使用部分移植物(分裂肝移植)和其他次优供体(高钠血症,感染,低血压和正性肌力支持)。
    During the last couple of decades, with standardization and progress in surgical techniques, immunosuppression and post liver transplantation patient care, the outcome of liver transplantation has been optimized. However, the principal limitation of transplantation remains access to an allograft. The number of patients who could derive benefit from liver transplantation markedly exceeds the number of available deceased donors. The large gap between the growing list of patients waiting for liver transplantation and the scarcity of donor organs has fueled efforts to maximize existing donor pool and identify new avenues. This article reviews the changing pattern of donor for liver transplantation using grafts from extended criteria donors (elderly donors, steatotic donors, donors with malignancies, donors with viral hepatitis), donation after cardiac death, use of partial grafts (split liver grafts) and other suboptimal donors (hypernatremia, infections, hypotension and inotropic support).
