Longer Operative Time Results in a Higher Rate of Subsequent Periprosthetic Joint Infection in Patients Undergoing Primary Joint Arthroplasty

Background

Whether prolonged operative time is an independent risk factor for subsequent surgical site infection (SSI) and periprosthetic joint infection (PJI) following total joint arthroplasty (TJA) remains a clinically significant and underexplored issue. The aim of this study is to investigate the association between operative time and the risk of subsequent SSI and PJI in patients undergoing primary TJA.

Circulating CCL20: A potential biomarker for active vitiligo together with the number of Th1/17 cells

Background

Vitiligo is an autoimmune disease with varying pathological features. Activation of the CCL20-CCR6 axis plays an important role in chronic inflammatory diseases. However, whether CCL20-CCR6 and Th1/17 cells are indicative of active vitiligo is unclear.

Health Care Utilization After Ventricular Tachycardia Ablation: A Propensity Score-Matched Cohort Study

Background

Catheter ablation of ventricular tachycardia (VT) can reduce the burden of ventricular arrhythmia (VA) but its effect on health care utilization and costs after such therapy is poorly known. We sought to compare the rates of cardiovascular (CV)-related hospitalizations, survival, and health care costs in patients with recurrent VT treated either with VT ablation or with medical therapy.

Impact of Multifocality and Multilocation of Positive Surgical Margin After Radical Prostatectomy on Predicting Oncological Outcome

Objective

To assess the impact of focality and location of positive surgical margins (PSM) on long-term outcomes after radical prostatectomy (RP) for prostate cancer (PCa), including biochemical recurrence (BCR), metastasis and overall mortality.

Association of malnutrition with all-cause mortality in the elderly population: A 6-year cohort study

Background and aimsFew studies have explored the association between malnutrition, defined by the Geriatric Nutritional Risk Index (GNRI), and all-cause mortality, particularly in the Chinese population. This study aimed to investigate the association between the GNRI and all-cause mortality in the elderly population.Methods and resultsParticipants aged ≥60 years were eligible for this study and were divided into three groups by the GNRI: An adequate nutrition group, participants with a GNRI ≥98; mild malnutrition group, participants with a GNRI ≥82 but <98; and a severe malnutrition group, participants with a GNRI <82. The results implied that there was a positive association between severe malnutrition and all-cause mortality in the total population (hazard ratio (HR): 2.591 and 95% confidence interval (CI): 1.729–3.884), male subjects (HR: 2.903 and 95% CI: 1.718–4.906), and female subjects (HR: 2.081 and 95% CI: 1.071–4.046). Similar associations between severe malnutrition and all-cause mortality were observed in both the 60–69 and 70–79 years age groups (HR: 2.863 and 2.600, 95% CI: 1.444–5.678 and 1.394–4.849, respectively). However, no significant association was observed between mild malnutrition and all-cause mortality.ConclusionsSevere malnutrition could increase all-cause mortality in the 60- to 79-year-old population. However, there was no association of mild malnutrition with all-cause mortality.     

胃癌D2根治术后大出血的临床分析

目的总结分析胃癌D2根治术后发生大出血的原因及治疗方法并探讨其对生存预后的影响。方法回顾性分析广东省中医院2012年1月至2016年3月258例行胃癌D2根治术患者的临床资料,根据术后是否发生大出血分为出血组和非出血组。结果14例患者(5.4%)术后发生大出血;吻合口出血、十二指肠残端瘘或破裂是出血的主要原因;二次手术和胃镜止血是主要治疗措施。两组的短期总生存期有统计学意义(1年:P=0.017,3年:P=0.011)。结论吻合口出血、十二指肠残端瘘或破裂是胃癌D2根治术后出血的主要原因,及时诊断和治疗能有效降低病死率。胃癌D2根治术后大出血会降低患者的短期总生存期。     

孕期抗病毒治疗结合标准阻断措施对乙型肝炎高病毒载量孕妇所生婴儿母婴传播阻断的影响

目的分析乙型肝炎(乙肝)病毒(Hepatitis B virus,HBV)高载量孕妇孕期HBV脱氧核糖核酸(HBV desoxyribonucleic acid,HBV-DNA)水平和HBVe抗原(HBV e antigen,HBeAg)阳性率以及孕期抗病毒治疗结合标准阻断措施对其所生婴儿母婴传播阻断失败率的影响。方法通过医院信息系统收集HBV-DNA高载量(≥2×10^6IU/mL)孕妇血清学检测结果、抗病毒药物使用等信息,描述HBV-DNA载量和HBeAg阳性率;对HBV-DNA高载量孕妇所生婴儿进行乙肝疫苗(Hepatitis B vaccine,HepB)和乙肝免疫球蛋白(Hepatitis B immunoglobulin,HBIG)联合免疫,在完成第3剂HepB后7月龄-2岁对乙肝表面抗原和HBV-DNA进行随访检测,分析母婴传播阻断失败率。结果共纳入1822名HBV-DNA高载量孕妇,接受、未接受抗病毒治疗分别占75.19%、24.81%。孕妇妊娠期、分娩前HBV-DNA≥1.0×10^8IU/mL比例分别为68.10%(933/1370)、0.15%(2/1370)(χ^2=2692.27,P<0.0001)。接受抗病毒治疗组妊娠期、分娩前HBeAg阳性率分别为96.53%(1001/1037)、96.16%(1251/1301)(χ^2=0.23,P=0.635),未接受抗病毒治疗组妊娠期、分娩前HBeAg阳性率分别为97.70%(298/305)、96.98%(417/430)(χ^2=0.36,P=0.550)。两组HepB和HBIG联合免疫后母婴传播阻断失败率分别为0.42%(3/714)、6.67%(14/210)(χ^2=31.69,P<0.0001)。结论孕妇HBV-DNA高载量以≥1.0×10^8IU/mL为主,孕期抗病毒治疗可显著降低孕妇HBV-DNA载量,结合HepB和HBIG联合免疫可显著降低其所生婴儿HBV母婴传播阻断失败率。

Associations between serum amino acids and incident type 2 diabetes in Chinese rural adults

Background and aimsSome amino acids (AAs) may be associated with type 2 diabetes (T2DM). This study aimed to determine the associations of individual AAs with the development of T2DM in rural Chinese adults.Methods and resultsA cohort study of 1199 individuals aged 18 years or older was conducted from 2006 to 2008 in a rural community of Deqing, China, a repeated survey was done in 2015 and data linkage with the electronic health records system was performed each year for identifying new T2DM cases. A high-performance liquid chromatography approach was used to measure the baseline serum concentrations of 15 AAs. Cox proportional hazards models were used to examine the associations between AAs and the risk of incident T2DM. A total of 98 new T2DM cases were identified during the follow-up of 12 years on average. Among 15 AAs, proline was associated with an increased risk of incident T2DM after adjusted for age, sex, body mass index, fasting plasma glucose, family history of T2DM, smoking status, alcohol use, and history of hypertension, the adjusted hazard ratio for 1-standard deviation increment was 1.20 (95% confidence interval: 1.00, 1.43). The association tended to be more marked in subjects younger than 60 years and overweight/obese subjects. Among participants without hypertension, proline and phenylalanine were associated with an increased risk of incident T2DM, while aspartic acid was associated with a decreased risk.ConclusionSerum proline was associated with the risk of incident T2DM in rural Chinese adults and might be a potential predictor.
