Background: Laparoscopic holmium laser lithotripsy (LHLL) has been used to treat bile duct stones with unclear outcomes. A meta-analysis was conducted to investigate the LHLL and laparoscopic bile duct exploration (LBDE) efficacy and safety in treating bile duct stones. Methods: The correlational studies were searched databases, such as PubMed, Embase, Cochrane Library, Web of Science, CNKI, Wanfang, and VIP, to identify eligible studies from inception to July 2022. The dichotomous and continuous outcomes were evaluated using odds ratio (OR), risk difference (RD) and weighted mean difference (WMD) with 95% confidence intervals (CIs). Stata 15.0 and Review Manager 5.3 software helped in data analyses. Results: A total of 23 studies with 1,890 patients, primarily from China, were included. The results indicated that operation time (WMD = − 26.94; 95% CI:(− 34.30, − 19.58); P < 0.00001), estimated blood loss (WMD = − 17.97; 95% CI: (− 22.94, − 13.00); P = 0.002), rate of residual stone (OR = 0.15, 95%CI: (0.10, 0.23); P < 0.00001), length of hospital stay (WMD = − 2.88; 95% CI:(− 3.80, − 1.96); P < 0.00001) and time to bowel function recovery (WMD = − 0.59; 95% CI: (− 0.76, − 0.41); P < 0.00001) had statistically significant differences between the two groups. In postoperative complications, biliary leakage (RD = -0.03; 95% CI: (− 0.05, -0.00); P = 0.02), infection (RD = − 0.06; 95% CI: (− 0.09,− 0.03); P < 0.00001) and Hepatic injury (RD = − 0.06; 95% CI: (− 0.11, − 0.01); P = 0.02) revealed statistically significant differences. However, no significant differences were observed in biliary damage (RD = − 0.03; 95% CI: (− 0.06, 0.00); P = 0.06) and hemobilia (RD = − 0.03; 95% CI: (− 0.06, 0.00); P = 0.08). Conclusion: The current meta-analysis indicated that LHLL could be more effective and safer than LBDC. However, these results should be confirmed with a larger sample size and rigorously designed randomized controlled trials. [ABSTRACT FROM AUTHOR]

Purpose: Evidence from several cohorts has suggested that a higher intake of isoflavone is associated with lower risk of lung cancer in never smokers, but the association has not been investigated by histologic type of lung cancer. Adenocarcinoma is a common histologic type found in never smokers. We hypothesized that a higher intake of isoflavone is associated with a lower risk of lung adenocarcinoma among never smokers. Here, we examined the associations of isoflavone and soy food intake with lung cancer and its histologic types in never smokers. Methods: We performed a pooled analysis using data from the Japan Public Health Center-based Prospective Study, Shanghai Women's Health Study and Shanghai Men's Study with 147,296 never smokers aged 40–74 years with no history of cancer. During 1,990,040 person-years of follow-up, 1247 lung cancer cases were documented. Dietary isoflavone and soy food intake were assessed using a food-frequency questionnaire. Multivariable Cox proportional hazards models assessed the associations between isoflavone and soy intake with incidence of lung cancer by histologic type. Results: A higher intake of dietary isoflavone and soy food were associated with reduced risk of lung adenocarcinoma. The multivariable hazard ratios (HRs) (95% CI) of risk of lung adenocarcinoma for the highest versus lowest intakes of isoflavone and soy food were 0.74 (0.60–0.92) and 0.78 (0.63–0.96), respectively. The multivariable HRs of risk of lung adenocarcinoma associated with each 10 mg/day increase in isoflavone and each 50 g/day increase in soy food intake were 0.81 (0.70–0.94) and 0.84 (0.73–0.96), respectively. Conclusion: Higher intake of isoflavone and soy food was associated with lower risk of lung adenocarcinoma in never smokers. [ABSTRACT FROM AUTHOR]

Ischemic heart disease (IHD) is one of the leading causes of mortality worldwide. Moreover, the effects of air pollution have been associated with several cardiovascular diseases (CVDs). The relationship between sandstorm weather and IHD is unknown. The Hexi Corridor is located in northwestern China and is a typical desert region comprising a large area of desert with a high incidence of sandstorms. This study aimed to explore the association between sandstorm weather and IHD-related mortality in this area. We acquired meteorological data of sandstorm weather from 2006 to 2015 from the Gansu Meteorological Bureau, and data regarding deaths due to IHD in five cities within the Hexi Corridor were collected from the death registration system of the Center for Disease Control of Gansu during the same period. Two other cities with few sandstorm events were selected as control regions. The time series method of the generalized additive model (GAM) was used to assess the association between sandstorm weather and IHD-related mortality in the Hexi Corridor. The results showed that the frequency of sandstorms in the Hexi Corridor was higher than that in the control regions (5.48% vs 1.64%, P < 0.01), and IHD-related mortality was correspondingly higher than that in the control regions (56.42/100,000 vs 45.62/100,000, P < 0.01). After stratification by gender, age, and urban/rural residence, a significant difference in IHD-related mortality was also noted (P < 0.05). Significant associations were found between sandstorm weather and IHD-related mortality, and the relative risk (RR) increased with an increasing number of days of sandstorm weather. According to the monthly and annual analyses, the mortality rate corresponded to sandstorm frequency. Our data suggest a positive association between sandstorm weather and IHD-related mortality in the Hexi Corridor of Gansu Province. The underlying mechanism requires further study.

Objective: The aim of this study was to estimate MS prevalence according to three criteria and its risk factors among men in rural China. Design: Cross-sectional study. Setting: The Nantong Metabolic Syndrome Study (NMSS) was conducted during 2007-2008 in Nantong, China. Participants: 6997 male participants aged 18-74 years. Measurements: In person interviews, blood glucose and lipid measurements were accomplished. Results: The prevalence of MS was 12.86%, 8.55% and 15.28% according to IDF, ATPIII and ATPIII-modified criteria, respectively. The IDF and ATP III-modified criteria agreed only moderately with ATP III criteria (ϰ= 0.56 and 0.68), whereas ATP III-modified and the IDF criteria agreed perfectly (ϰ= 0.90). Vigorous occupational physical activity was associated with a low prevalence of MS with Odds ratio (OR) of 0.58 (95% confidence interval (CI): 0.45-0.74). Beer drinkers (alcohol ≤ 6.2 g/day) and rice wine drinkers (alcohol ≤ 9.0 g/day) had about 34% and 33% low risks of developing MS respectively, compared with non-drinkers. OR of MS was 1.95 (95% CI: 1.39-2.73) in men who had familial history of at least two diseases, including hypertension and diabetes, compared with men without familial history of those diseases. Conclusions: Our data suggested that MS is highly prevalent among men in rural China. Family history of diabetes and hypertension is a risk factor in MS development. Physical activity, rice wine and beer consumption are associated with a significantly lower risk. [ABSTRACT FROM AUTHOR]

The aim of this study was to evaluate the influence of body mass index (BMI), weight change on triple-negative breast cancer (TNBC) prognosis in a population-based prospective cohort study. The current analysis included 518 participants diagnosed with TNBC in Shanghai Breast Cancer Survival Study. Weight at 1 year prior to cancer diagnosis, at diagnosis, and at 6, 18 and 36 months after cancer diagnosis and height at 6 months after cancer diagnosis were assessed. Disease-free survival (DFS) and overall survival (OS) were evaluated in relation to BMI and weight change using Cox proportional hazard models. Obesity (BMI ≥ 28.0 kg/m(2)) at 1-year pre-diagnosis was associated with higher risk of total mortality and recurrence/disease-specific mortality, with multivariate hazard ratios (HRs) of 1.79 (95 % CI 1.06-3.03) and 1.83 (95 % CI 1.05-3.21), respectively. The associations between BMI and TNBC prognosis attenuated over time from pre-diagnosis to post-diagnosis. Compared with stable weight (change within 5 %), weight loss ≥5 % at 18- or 36-month post-diagnosis was related with higher risk of total mortality and recurrence/disease-specific mortality. Respective multivariate HRs were 2.08 (95 % CI 1.25-3.46) and 1.42 (95 % CI 0.77-2.63) for OS, and 2.50 (95 % CI 1.45-4.30) and 2.17 (95 % CI 1.14-4.12) for DFS. However, the association of weight loss and OS/DFS attenuated after excluding patients whose weight was measured after recurrence. Weight gain ≥5 % at 18- or 36-month post-diagnosis was associated with a non-significant increased risk of death. The results showed that obesity pre-diagnosis and weight loss post-diagnosis was inversely associated with TNBC prognosis. Emphasis on maintaining stable weight after cancer diagnosis for TNBC patients may be considered. [ABSTRACT FROM AUTHOR]
