Abstract
Background Gallstones are a significant global health issue, imposing enormous costs to patients and the healthcare system, annually. Objectives This epidemiological study aimed to explore the prevalence of gallstones among inpatients who were admitted to Shahid Rahimi Hospital in Khorramabad City, Iran, from 2016 to 2020. Methods This was a retrospective and descriptive-analytical study. The study population included patients who were admitted to Shahid Rahimi Hospital in Khorramabad City, Iran, who underwent abdominal ultrasounds from 2016 to 2020. The required data were collected using a checklist and patients' records. The logistic regression analysis method was used to analyse the obtained data in SPSS at the significance level of P<0.05. Results Of the 927 explored subjects, 232(25%) presented gallstones. The mean age of the patients with gallstones was 62.9 years. The most frequent symptom in individuals with gallstones was right upper quadriceps abdominal pain (63%). There was a significant relationship between gallstone and age, gender, epigastric pain, upper quadrant pain, hypertension, anemia, and family history. Conclusion The present study findings indicated that increasing age, female gender, the lack of epigastric pain, upper quadrant pain, anemia, hypertension, and a family history of this disease increased the risk of generating gallstone disease.

Abstract
BACKGROUND & AIMS Presence of gallstone disease may influence outcomes in patients with nonalcoholic fatty liver disease (NAFLD). We studied the impact of gallstone disease on mortality in individuals with and without NAFLD. METHODS Prospective cohort study used the Third National Health and Nutrition Examination Survey (1988-1994) with mortality data through 2015. Gallstone disease was defined as ultrasonographic evidence of gallstones or absence of the gallbladder (prior cholecystectomy). NAFLD was defined using standardized ultrasonographic criteria. RESULTS Gallstone disease and cholecystectomy were independently associated with NAFLD (odds ratio [OR], 1.75; 95% confidence interval [CI], 1.43-2.15 for gallstone disease and OR, 2.77; 95% CI, 2.01-3.83 for cholecystectomy compared with no gallstone disease). During the median follow-up of 23 years, gallstone disease was associated with a higher risk of all-cause mortality (hazard ratio [HR], 1.19; 95% CI, 1.05-1.37) and cause-specific mortality. Gallstone disease was associated with a higher risk of all-cause mortality in non-NAFLD sub-cohort (HR, 1.42; 95% CI, 1.23-1.64) but not in NAFLD (HR, 1.03; 95% CI, 0.87-1.22). Gallstone disease was associated with a higher risk of cardiovascular-related (HR, 1.40; 95% CI, 1.10-1.78) and cancer-related (HR, 1.71; 95% CI, 1.18-2.48) mortality in non-NAFLD sub-cohort. Gallstone disease was associated with increased cardiovascular mortality (HR, 1.36; 95% CI, 1.05-1.77) in NAFLD. CONCLUSIONS Gallstone disease is an independent risk factor for NAFLD, but gallstone disease is not associated with all-cause mortality in individuals with NAFLD. Screening for gallstone disease in individuals at risk for developing NAFLD may help with risk stratification for all-cause mortality related to gallstone disease.

Abstract
Background Factors of metabolic syndrome such as obesity are well-known risk factors for gallstone disease (GSD). There are different indicators of obesity, including weight, body mass index, waist circumference, and waist-to-height ratio. The predictive ability of different obesity indicators for GSD remains unclear. Objective To explore the most efficient predictor of GSD among the different anthropometric indicators of obesity. Methods This population-based cross-sectional study included 2263 participants who completed a questionnaire detailing their demographics, medical history, and lifestyle between 2014 and 2017 in Taiwan. Blood samples were collected and physical examinations, including anthropometric measurements, were performed. Gallstone disease was ascertained using ultrasonography. Multivariate analyses were performed to identify independent risk factors for GSD. Results The overall prevalence of GSD was 8.8%. According to the multivariate analysis, individuals with a waist-to-height ratio ≥0.5 (odds ratio|odds ratios (OR) = 1.65, 95% confidence interval (CI) = 1.10-2.48, p = 0.017) had an increased risk of GSD. Diabetes was the main risk factor for GSD in men (OR = 2.06, 95% CI = 1.17-3.65, p = 0.013). Among women, waist-to-height ratio >0.5 (OR = 1.76, 95% CI = 1.03-3.02, p = 0.040) and current hormone drug use (OR = 2.73, 95% CI = 1.09-6.84, p = 0.033) were significant risk factors for gallstones. Conclusion GSD was independently associated with central obesity and exogenous hormone intake in women. Among the anthropometric indicators used to assess central obesity, waist-to-height ratio was the most accurate predictor of GSD.

Abstract
BACKGROUND The occurrence of stones in the gallbladder or common bile duct and the symptoms and complications they cause is called gallstone disease. The symptoms of gallstone disease range from mild, nonspecific symptoms to a severe right quadrant abdominal pain. Characteristics of gallstone types in an Iranian population have not been well studied before and there are very limited studies on the demographic pattern of stone types in our country, so this study is one of the first studies on its kind on the epidemiology of gallstone types in Iran. As information on chemical components of the stone will help in the management and prevention of gallstones, in this study, we aimed to do chemical component analysis of gallstones including cholesterol, bilirubin, and calcium. Given the conflicting reports about the relationship between H. pylori infections and gallstone formation, this study aimed to investigate the relationship between H. pylori positivity in the bile specimen of Iranian patients with cholelithiasis and formation and type of stone. METHODS This prospective study reviewed a total of 196 patients who underwent cholecystectomy for symptomatic cholelithiasis at Shahid Beheshti Training and Research Hospital affiliated to the Yasuj University of Medical Sciences between September 2015 and May 2018. Chemical analysis of gallstone components performed using the colorimetry method. Microbiological analysis for H. pylori was done using the OnSite H. pylori Ag Rapid Test on the bile sample. For the validation test of bile, the H. pylori Rapid Stool Ag Test on stool was used, and Cohen's Kappa statistical analysis was done next. RESULTS There were significant associations between the stone types and age, chemical composition of the stones such as calcium, cholesterol, and bilirubin levels, and also H. pylori positivity and cholesterol and bilirubin levels; however, no significant association was found between the stone types and sex, H. pylori positivity and age, sex, stone types, and calcium level. The main bile and validity tests were matched to the substantial agreement according to Cohen's Kappa analysis. The most common drugs used were proton pump inhibitors, nonsteroidal anti-inflammatory drugs, antihypertensive drugs, and oral contraceptives. CONCLUSIONS This study suggested that the chemical composition of the stones could predict the presence of bacteria, there is no correlation between H. pylori and gallstone formation, and some of the drugs could be predisposing factors for gallstones. This work provides an objective basis for further research into gallbladder stone formation; meanwhile, it has great significance in the treatment and prevention of gallbladder stones. Trial registration. The project was found to be in accordance to the ethical principles and the national norms and standards for conducting research in Iran with the approval ID IR.YUMS.REC.1399.147 and date 2020.09.23, and this project is the result of a residency dissertation to obtain the specialty in general surgery, which has been registered with the research project number 960159 in the Vice Chancellor for Research and Technology Development of the Yasuj University of Medical Sciences, Yasuj, Iran, URL: https://ethics.research.ac.ir/EthicsProposalViewEn.php?id=160634.

Abstract
Background Gallbladder stone is recently increased among the Iraqi society due to many risk factors such as bacterial infection and some HLA class II antigens. Aim(s) This study investigates the types of bacterial infection and HLA-DRB1 antigens' ratio that may be correlated with gallbladder stone formation. Setting and Design: The study included 45 patients and the same number of healthy individuals as a control group. Patients were with multiple gallstones. Gallstone bacterial culture was demonstrated to diagnose viable bacteria. HLA-DRB1 alleles' frequency was investigated using sequence-specific oligonucleotide probes (PCR-SSOP). Results Irrespective of gallstone type and size, different types of living viable bacteria were isolated from the cores of the studied gallstones in 80% of the studied cases versus 20% of sterile gallstones. Gram-negative bacteria cultures were the dominant (89.3%), including Escherichia coli, Klebsiella spp., Proteus spp., Acinetobacter spp., and Enterobacter spp. Mixed infection of Gram-positive and negative bacteria was noted: Escherichia coli and Enterococus spp. and the others of Escherichia coli and Acitobacter spp., and Klebsiella spp. and Pseudomonas spp. Gram-positive bacteria cultures were also detected at lower rate (10.7%) including Staphylococci spp. The frequency of HLA-DRB1*03:01, HLA-DRB1*4:03, HLA-DRB1*13:22, and HLA-DRB1*15:10 alleles was significantly elevated in patients compared to the healthy control group. Conclusion Results ensured the viability of the bacteria isolated from the core of gallstones and showed positive correlation between gallbladder stone and different bacterial infection. In addition, HLA-DRB1 alleles were significantly high in patients compared to healthy control group suggesting them as risk factors (P < 0.05).

Abstract
PURPOSE Previous studies have indicated an increased risk of gallbladder disease with hormonal contraceptives although with discordant results. The potential increased risk of gallbladder disease with hormonal contraceptives is concerning given that women are at increased risk of this disease. Thus, the aim of this study was to examine risk of surgery-confirmed gallbladder disease (cholecystectomy) with oral contraceptives, intrauterine devices, and injectable hormonal contraceptives. METHODS We conducted a retrospective cohort study. Females aged 15-45 who initiated hormonal contraceptive use were identified in the United States IQVIA Ambulatory electronic medical record database between 2008 and 2018. Cox proportional hazards models were used to estimate adjusted hazards ratios and 95% confidence intervals for cholecystectomy with eight formulations of contraceptives compared with levonorgestrel and ethinyl estradiol combined oral contraceptive. Sensitivity analysis was conducted by lagging exposure by 90 days and by excluding patients with history of gallbladder disease. Secondary analyses were conducted by cumulative duration of use. RESULTS We identified 1,425,821 females who initiated the use of hormonal contraceptives and generated 4417 cholecystectomy events. Overall, the use of medroxyprogesterone acetate (HR: 1.22, 95% CI: 1.07-1.40) and at least 1 year of levonorgestrel intrauterine device use (HR: 1.74: 95% CI: 1.19-2.54) were associated with increased risk of cholecystectomy when compared with levonorgestrel and ethinyl estradiol combined oral contraceptive. However, we did not observe an increased risk with other hormonal contraceptives. Consistent results were observed across sensitivity analyses. CONCLUSION In this large population-based study, there was an increased risk of cholecystectomy with medroxyprogesterone acetate and intrauterine device but not other hormonal contraceptives. Additional large observational studies are required to corroborate these findings.

Abstract
BACKGROUND It has been claimed that smoking is linked with an increased risk for gallbladder disease (GBD); however, related issues need further consolidation and clarification. The present systematic review and meta-analysis aimed to further investigate the potent correlation between GBD and smoking. METHODS We conducted a comprehensive literature review to identify every study published from January 1989 to December 2019, reporting risk estimates regarding GBD and smoking. The random-effect, generic inverse variance method, according to description by DerSimonian and Laird, was used to compute pooled estimates. We used the Newcastle-Ottawa quality assessment scale to appraise the included studies' quality. RESULTS Thirty published case-control, cross-sectional, and cohort studies including 4,623,435 individuals met the eligibility criteria and were considered for data synthesis. Compared to the non-smokers, ever smokers had 1.25 times higher odds of developing GBD [95 % confidence interval (CI): 1.09-1.44]; however, increased heterogeneity was observed (I2 =96 %, 95 % CI: 62-100 %, p <0.001). Publication bias was non-significant (Eggers' regression p =0.072). The main sources of heterogeneity, as detected by meta-regression analyzing study characteristics, biases and confounders, were non-adjustment for family history (p =0.007) and alcohol (p =0.020), respectively. Subgroup analysis indicated a comparable risk for GBD as far as current, former and ever smokers are concerned (p =0.520). Quantitative analysis suggested a dose-effect for current smoking and GBD (p =0.010). CONCLUSIONS Non-smokers were demonstrated to be at a lower risk of presenting GBD when compared with ever smokers; all relevant risk estimates necessitate adjustment for family history and alcohol intake.

Abstract
INTRODUCTION The levonorgestrel oral emergency contraceptive is well tolerated and effective, however its use is still limited, mainly due to safety concerns. OBJECTIVE This systematic review and meta-analysis aimed to summarize current evidence regarding the adverse events, and their prevalence, reported during the use of oral levonorgestrel emergency contraceptives. METHODS Four electronic databases and the US FDA Adverse Event Reporting System (FAERS) Public Dashboard were searched. Studies that reported or investigated safety outcomes or adverse reactions during the use of levonorgestrel as an emergency oral contraceptive were included. Data on study design, demographics of levonorgestrel and the control cohort, and reported adverse effects were extracted. RESULTS A total of 47 articles were included in this systematic review, from which it was shown that most of the adverse reactions were common and not serious. Uncommon adverse reactions identified included anorexia, ectopic pregnancy, exanthema, chloasma, miscarriage, and weight gain. Multiple serious adverse events, including convulsion, ectopic pregnancy, febrile neutropenia, stroke, abdominal hernia, anaphylaxis, cancer, ovarian cyst rupture, serious infections, and suicidal ideation, were reported. In addition, the prevalence of adverse events after a levonorgestrel 0.75 mg two-dose regimen and a levonorgestrel 1.5 mg single-dose regimen were not statistically different (p > 0.05). CONCLUSIONS The most common adverse effects of levonorgestrel were not serious. This systematic review shows that data regarding the adverse reactions of repeated use of levonorgestrel are scarce. Studies on the multiple uses of levonorgestrel emergency contraception are still required to ensure its safety.

Abstract
BACKGROUND & AIMS The incidence and predictors of non-gastrointestinal (GI) adverse events (AEs) after colonoscopy are not well-understood. We studied the effects of antithrombotic agents, cardiopulmonary comorbidities, and age on risk of non-GI AEs after colonoscopy. METHODS We performed a retrospective longitudinal analysis to assess the diagnosis, procedure, and prescription drug codes in a United States commercial claims database (March 2010-March 2012). Data from patients at increased risk (n = 82,025; defined as patients with pulmonary comorbidities or cardiovascular disease requiring antithrombotic medications) were compared with data from 398,663 average-risk patients. In a 1:1 matched analysis, 51,932 patients at increased risk, examined by colonoscopy, were compared with 51,932 matched (on the basis of age, sex, and comorbidities) patients at increased risk who did not undergo colonoscopy. We tracked cardiac, pulmonary, and neurovascular events 1-30 days after colonoscopy. RESULTS Thirty days after outpatient colonoscopy, non-GI AEs were significantly higher in patients taking antithrombotic medications (7.3%; odds ratio [OR], 10.75; 95% confidence interval, 10.13-11.42) or those with pulmonary comorbidities (1.8%; OR, 2.44; 95% confidence interval, 2.27-2.62) vs average-risk patients (0.7%) and in patients 60-69 years old (OR, 2.21; 95% confidence interval, 2.01-2.42) or 70 years or older (OR, 6.45; 95% confidence interval, 5.89-7.06), compared with patients younger than 50 years. The 30-day incidence of non-GI AEs in patients at increased risk who underwent colonoscopy was also significantly higher than in matched patients at increased risk who did not undergo colonoscopy in the anticoagulant group (OR, 2.31; 95% confidence interval, 2.01-2.65) and in the chronic obstructive pulmonary disease group (OR, 1.33; 95% confidence interval, 1.13-1.56). CONCLUSIONS Increased number of comorbidities and older age (older than 60 years) are associated with increased risk of non-GI AEs after colonoscopy. These findings indicate the importance of determining comorbid risk and evaluating antithrombotic management before colonoscopy.

Abstract
BACKGROUND Diabetes has been hypothesized to increase the risk of gallbladder disease based on the observation that obesity and insulin resistance are associated with gallbladder disease. Although several studies have investigated the association between a diabetes diagnosis and risk of gallbladder disease, the results have not been entirely consistent. For this reason we conducted a systematic review and meta-analysis of the available cohort studies. MATERIALS AND METHODS We searched the PubMed and Embase databases for studies of diabetes and gallbladder disease (defined as gallstones, cholecystectomy, or cholecystitis) up to January 9th 2015. Prospective studies were included if they reported relative risk estimates and 95% confidence intervals of gallbladder disease associated with a diabetes diagnosis. Summary relative risks were estimated by use of a random effects model. RESULTS We identified 10 prospective studies that could be included in the meta-analysis which included 223,651 cases among 7,365,198 participants. The summary RR for diabetes patients was 1.56 (95% CI: 1.26-1.93, I(2)=99.4%, pheterogeneity<0.0001). The results persisted when stratified by gender, and in most subgroup analyses and there was no heterogeneity among studies with more than 10 years duration of follow-up. There was no evidence of publication bias. CONCLUSIONS Our analysis provides further support for an increased risk of gallbladder disease among diabetes patients.

Abstract
Tobacco smoking has been inconsistently associated with gallbladder disease risk. To clarify the association we conducted a systematic review and meta-analysis of cohort studies published on the subject. We searched the PubMed and Embase databases for studies of smoking and gallbladder disease up to January 9th 2015. Prospective studies were included if they reported relative risk estimates and 95 % confidence intervals of gallbladder disease associated with current, former or ever smoking and by number of cigarettes per day. Summary relative risks were estimated by use of a random effects model. We identified ten prospective studies including 59,530 gallbladder disease cases among 4,213,482 participants that could be included in the meta-analysis. The summary RR was 1.19 (95 % CI 1.12-1.28, I(2) = 46.9 %, n = 6) for current smokers, 1.10 (95 % CI 1.07-1.13, I(2) = 0 %, n = 6) for former smokers and 1.15 (95 % CI 1.13-1.18, I(2) = 0 %, n = 7) for ever smokers. In the dose-response analysis the summary relative risk was 1.11 (95 % CI 1.08-1.14, I(2) = 33 %, n = 3) per 10 cigarettes per day and although there was indication of nonlinearity there was a dose-dependent positive association with increasing number of cigarettes smoked per day. The current meta-analysis provides evidence of an increased risk of gallbladder disease associated with tobacco smoking.

Body mass index, abdominal fatness and the risk of gallbladder disease. Eur J Epidemiol 2015; 30:1009-19.

Abstract
Epidemiological studies have indicated a positive association between adiposity and gallbladder disease risk, however, the shape of the dose-response relationship and differences between overall and abdominal adiposity remains to be clarified. We conducted a systematic review and dose-response meta-analysis of cohort studies of body mass index (BMI), waist circumference and waist-to-hip ratio and risk of gallbladder disease. PubMed and Embase databases were searched up to January 9th 2015. Summary relative risks were calculated using a random effects model. Seventeen prospective studies of BMI and gallbladder disease risk with 55,670 cases among 1,921,103 participants were included. The summary relative risk (RR) for a 5 unit increment in BMI was 1.63 (95 % CI 1.49-1.78, I(2) = 98 %). There was evidence of a nonlinear association overall and among women, p(nonlinearity) < 0.0001, but not among men, p(nonlinearity) = 0.99, with a slight flattening of the curve at very high BMI levels (BMI 40-45), however, the risk of gallbladder disease increased almost twofold even within the "normal" BMI range. The summary RR for a 10 cm increase in waist circumference was 1.46 (95 % CI 1.24-1.72, I(2) = 98 %, n = 5) and for a 0.1 unit increment in waist-to-hip ratio was 1.44 (95 % CI 1.26-1.64, I(2) = 92 %, n = 4). Associations were attenuated, but still significant, when BMI and abdominal adiposity measures were mutually adjusted. Our results confirm a positive association between both general and abdominal fatness and the risk of gallbladder disease. There is an almost twofold increase in the risk even within the "normal" BMI range, suggesting that even moderate increases in BMI may increase risk.

Abstract
BACKGROUND Recent studies have provided conflicting and controversial results about the risk of cardiovascular events, including myocardial infarction (MI), with testosterone replacement therapy (TRT). The potential adverse effects of different TRT formulations and duration of therapy on MI risk are unknown. METHODS We performed a case-control study within a cohort of 934,283 men aged 45-80 from the IMS LifeLink Health Plan Claims Database. For each case of MI, four controls were identified using density-based sampling. Rate ratios (RRs) were computed for current and past TRT users. As a sensitivity analysis, the risk of MI before and after the start of a first-time TRT prescription in the same patient was also computed. RESULTS We identified 30,066 MI cases and 120,264 corresponding controls. Current use of TRT was not associated with an increased risk of MI (RR 1.01, 95% confidence interval [CI] 0.89-1.16); first-time users did show an increased risk (RR 1.41, 95% CI 1.06-1.87; number needed to harm 305). There was no association between MI and past TRT users and no differences among the different formulations. The RRs for current use and first-time use of TRT in men with a previous history of coronary artery disease were 1.05 (95% CI 0.79-1.41) and 1.78 (95% CI 0.93-3.40), respectively. CONCLUSION In this large observational study, an association between MI and past or current TRT use was not found. However, a statistically significant association was observed between first-time TRT exposure and MI, although the absolute risk was low.

Abstract
OBJECTIVE to describe the frequency and the factors associated with cholelithiasis in obese adolescents. METHODS this was a cross-sectional descriptive study performed with the adolescents between 10 and 19 years of age treated at the Child and Adolescent Obesity Outpatient Clinic from May to December of 2011. Obesity was defined as body mass index (BMI)>P97, and overweight as BMI>P85, for age and gender, according to the 2007 World Health Organization reference. A questionnaire concerning the presence of signs and symptoms, such as abdominal pain, nausea, vomiting, and intolerance to fat, was administered. Patients were asked about how many kilograms they had lost and in how much time. Laboratory parameters were: triglycerides, total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) levels. Cholelithiasis and hepatic steatosis were diagnosed by ultrasonography. RESULTS cholelithiasis was diagnosed in 6.1% (4/66) of the obese adolescents, most of whom were female (3/4); hepatic steatosis was identified in 21.2% (14/66). Intolerance to dietary fat was reported by all patients with cholelithiasis (4/4) and by 17.7% (11/62) of the group without cholelithiasis (p=0.001). The average weight loss was 6.0 ± 2.9 kg in the patients with cholelithiasis and 3.2 ± 4.8 kg in the group without cholelithiasis (p=0.04). However, there was no difference between the two groups regarding the time of weight loss (p=0.11). CONCLUSIONS cholelithiasis and hepatic steatosis are frequent among obese adolescents and should be investigated systematically in the presence or absence of symptoms.

Abstract
Although female use of hormonal contraceptives (HCs) has been associated with a variety of physical side effects, the psychological and behavioral side effects have received comparatively little attention until recently. Indeed, the long-term impact of HC use on human psychology has been vastly under-researched and has only recently become a focus for mainstream scholars. Women who use HCs report higher rates of depression, reduced sexual functioning, and higher interest in short-term sexual relationships compared to their naturally-cycling counterparts. Also, HC use may alter women's ability to attract a mate, as well as the mate retention behaviors in both users and their romantic partners. Some evidence even suggests that HC use alters mate choice and may negatively affect sexual satisfaction in parous women, with potential effects on future offspring. Interestingly, HCs have become a standard method of population control for captive nonhuman primates, opening up exciting avenues for potential comparative research. Here, the existing literature on the psychobehavioral effects of HCs in humans and nonhuman primates is reviewed and discussed. The potential resulting downstream consequences for the path of human evolution and recommendations for how future research could tease apart the underlying causes of these psychobehavioral effects of HC use are discussed, including suggestions for research involving nonhuman primates.

Abstract
BACKGROUND Case reports indicate that the use of fluoroquinolones may lead to acute kidney injury. We studied the association between the use of oral fluoroquinolones and acute kidney injury, and we examined interaction with renin-angiotensin-system blockers. METHODS We formed a nested cohort of men aged 40-85 enrolled in the United States IMS LifeLink Health Plan Claims Database between 2001 and 2011. We defined cases as men admitted to hospital for acute kidney injury, and controls were admitted to hospital with a different presenting diagnosis. Using risk-set sampling, we matched 10 controls to each case based on hospital admission, calendar time (within 6 wk), cohort entrance (within 6 wk) and age (within 5 yr). We used conditional logistic regression to assess the rate ratio (RR) for acute kidney injury with current, recent and past use of fluoroquinolones, adjusted by potential confounding variables. We repeated this analysis with amoxicillin and azithromycin as controls. We used a case-time-control design for our secondary analysis. RESULTS We identified 1292 cases and 12 651 matched controls. Current fluoroquinolone use had a 2.18-fold (95% confidence interval [CI] 1.74-2.73) higher adjusted RR of acute kidney injury compared with no use. There was no association between acute kidney injury and recent (adjusted RR 0.87, 95% CI 0.66-1.16) or past (RR 0.86, 95% CI 0.66-1.12) use. The absolute increase in acute kidney injury was 6.5 events per 10 000 person-years. We observed 1 additional case per 1529 patients given fluoroquinolones or per 3287 prescriptions dispensed. The dual use of fluoroquinolones and renin-angiotensin-system blockers had an RR of 4.46 (95% CI 2.84-6.99) for acute kidney injury. Our case-time-control analysis confirmed an increased risk of acute kidney injury with fluoroquinolone use (RR 2.16, 95% CI 1.52-3.18). The use of amoxicillin or azithromycin was not associated with acute kidney injury. INTERPRETATION We found a small, but significant, increased risk of acute kidney injury among men with the use of oral fluoroquinolones, as well as a significant interaction between the concomitant use of fluoroquinolones and renin-angiotensin-system blockers.

Abstract
The October 2010 ESHRE/ASRM polycystic ovary syndrome (PCOS) workshop concluded: (1) all combined oral contraceptives (COC) appear to have equal efficacy for PCOS, (2) addition of antiandrogens (spironolactone) to COCs has little treatment benefit and (3) metformin does not improve the live-birth rate and should only be used with impaired glucose tolerance. We compared these guidelines to current practice in the United States IMS claims-database. Time-series analyses were conducted by calendar-year in women with PCOS to evaluate prescribing preferences for COCs, concomitant use of spironolactone, and utilization of metformin. Trends were analyzed with linear regression. Our cohort included 1.6 million women taking COCs, 46 780 with a PCOS claim. Drospirenone utilization increased by 1.52% (SE:0.48%, p = 0.007) per-year more in women with PCOS (4.16%, SE:0.45%, p < 0.001) than in women without PCOS (2.64%, SE:0.17%, p < 0.001)). Concomitant use of drospirenone and spironolactone was common (14.26%) and increased by 0.75% (SE:0.15%, p = 0.002) per-year. Although plasma glucose tests were unavailable, women with PCOS were more likely to take metformin than have a diabetes claim (45.8% versus 15.2%, p < 0.001), indicating some women likely receive metformin solely for PCOS. Our data suggests further attention is needed to medication management of PCOS to bridge the gap between guidelines and practice.

Abstract
BACKGROUND There is an increased risk of venous thromboembolism among women taking oral contraceptives. However, whether there is an additional risk among women with polycystic ovary syndrome (PCOS) is unknown. METHODS We developed a population-based cohort from the IMS LifeLink Health Plan Claims Database, which includes managed care organizations in the United States. Women aged 18-46 years taking combined oral contraceptives and who had a claim for PCOS (n = 43 506) were matched, based on a propensity score, to control women (n = 43 506) taking oral contraceptives. Venous thromboembolism was defined using administrative coding and use of anticoagulation. We used Cox proportional hazards models to assess the relative risk (RR) of venous thromboembolism among users of combined oral contraceptives with and without PCOS. RESULTS The incidence of venous thromboembolism among women with PCOS was 23.7/10 000 person-years, while that for matched controls was 10.9/10 000 person-years. Women with PCOS taking combined oral contraceptives had an RR for venous thromboembolism of 2.14 (95% confidence interval [CI] 1.41-3.24) compared with other contraceptive users. The incidence of venous thromboembolism was 6.3/10 000 person-years among women with PCOS not taking oral contraceptives; the incidence was 4.1/10 000 person-years among matched controls. The RR of venous thromboembolism among women with PCOS not taking oral contraceptives was 1.55 (95% CI 1.10-2.19). INTERPRETATION We found a 2-fold increased risk of venous thromboembolism among women with PCOS who were taking combined oral contraceptives and a 1.5-fold increased risk among women with PCOS not taking oral contraceptives. Physicians should consider the increased risk of venous thromboembolism when prescribing contraceptive therapy to women with PCOS.

Abstract
Diseases of the gallbladder are common and costly. The best epidemiological screening method to accurately determine point prevalence of gallstone disease is ultrasonography. Many risk factors for cholesterol gallstone formation are not modifiable such as ethnic background, increasing age, female gender and family history or genetics. Conversely, the modifiable risks for cholesterol gallstones are obesity, rapid weight loss and a sedentary lifestyle. The rising epidemic of obesity and the metabolic syndrome predicts an escalation of cholesterol gallstone frequency. Risk factors for biliary sludge include pregnancy, drugs like ceftiaxone, octreotide and thiazide diuretics, and total parenteral nutrition or fasting. Diseases like cirrhosis, chronic hemolysis and ileal Crohn's disease are risk factors for black pigment stones. Gallstone disease in childhood, once considered rare, has become increasingly recognized with similar risk factors as those in adults, particularly obesity. Gallbladder cancer is uncommon in developed countries. In the U.S., it accounts for only ~ 5,000 cases per year. Elsewhere, high incidence rates occur in North and South American Indians. Other than ethnicity and female gender, additional risk factors for gallbladder cancer include cholelithiasis, advancing age, chronic inflammatory conditions affecting the gallbladder, congenital biliary abnormalities, and diagnostic confusion over gallbladder polyps.
