Abstract
Few previous review articles have focused on the associations between inadequate daily water intake (LOW) or urinary biomarkers of dehydration (UD; low urine volume or high urine osmolality) and multiple diseases. Accordingly, we conducted manual online searches (47 key words) of the PubMed, Embase, and Google Scholar databases with these inclusion criteria: English language, full-text, peer reviewed, no restriction on research design, and three publications minimum. Initially, 3,903 articles were identified based on their titles and abstracts. Evaluations of full length .pdf versions identified 96 studies that were acceptable for inclusion. We concluded that the evidence is insufficient or conflicting for seven disorders or diseases (i.e. suggesting the need for additional clarifying research) and it is lacking for all-cause mortality. Differential characterizations among women and men have been reported in the results of nine studies involving five diseases. Finally, the evidence for associations of LOW or UD is strong for both kidney stones and type 2 diabetes with hyperglycemia. This suggests that great public health value (i.e. reduced disease risk) may result from increased daily water intake-a simple and cost-effective dietary modification.

Abstract
BACKGROUND The global prevalence of noncommunicable diseases has risen rapidly over the past decade. Research has focused on dietary management, particularly dietary sugar, to prevent and treat noncommunicable diseases. OBJECTIVE This study undertakes a scoping review of research on the impacts of dietary sugar on cardiometabolic related health outcomes. METHODS Ovid Medline, Scopus and Web of Science Core collection databases were used to identify papers published from January 1, 2010 onwards. The included studies had to be cross-sectional or cohort studies, peered review, published in English and in adults, aged 18 years old and above. Articles had to determine the impacts of sugar intake on cardiometabolic related health outcomes. Study quality was measured using the Quality Assessment Tool for Observational Cohort and Cross-sectional Studies. In addition, a narrative synthesis of extracted information was conducted. RESULTS Thirty-one articles were included in this review. All studies had a large sample size, and the exposure measure was clearly defined, valid and applied consistently across all study participants. Exposure was measured using validated questionnaires. All data were statistically analysed and adjusted for critical potential confounding variables. Results showed that dietary sugar intake was significantly associated with metabolic syndrome, blood pressure, blood glucose, blood lipids, and body weight. CONCLUSION Dietary sugar intake significantly increased cardiometabolic risks through mechanisms dependent and independent of weight gain. It is essential to create public awareness on the topics of cardiometabolic risk management and dietary sugars intake.

Abstract
BACKGROUND & AIMS Gallstone disease (GD) is a major cause for consultation at general surgery services worldwide. In fact, GD has a strong relationship with environmental factors. However, specific characteristics in the Mexican population have not been established. The aim of this study was to compare the dietary components, physical activity, body composition and serum lipids in women with and without GD. METHODS 54 women with GD and 75 without GD from West Mexico were enrolled in a cross-sectional study. Dietary intake was obtained through a habitual day food record and analyzed using the Nutritionist Pro™ software. Physical activity was evaluated in accordance with WHO recommendations. Body fat percentage (BF%) was estimated by bioimpedance (InBody 370) and serum lipids were measured using dry chemistry (Vitros-250 Analyzer). Student's t-test and binary logistic regression model were used. RESULTS Women with GD presented a higher BF% (40 ± 8.7 vs 35.21 ± 9.8%, p = 0.004), an elevated dietary ω-6:ω-3 polyunsaturated fatty acids (PUFA) ratio (18.0 ± 11.4 vs 10.9 ± 4.7, p<0.001) and a higher simple carbohydrates (sCH) intake (28.3 ± 17.8 vs 13.23 ± 8.2%, p<0.001) as well as lower HDL-cholesterol levels (37.43 ± 8.5 vs 46.6 ± 12.02 mg/dL, p<0.001) compared with women without GD. Furthermore, it was foun d a higher ω-6:ω-3 PUFA ratio (OR: 3.9, 95% CI 1.52-10.38, p = 0.005) and excessive sCH consumption (OR: 7.4, 95% CI 1.92-28.65, p = 0.004). CONCLUSION We suggest that a high dietary ω-6:ω-3 PUFA ratio and an excessive sCH intake are associated with an increased risk of GD in women.

Abstract
Background Approximately one fifth of adults are diagnosed with gallstones worldwide. Of these, around 25% develop gallstone disease (indicated by the presence of symptoms) and undergo cholecystectomy. Summary The risk of gallstones is influenced by a combination of genetic and lifestyle factors, such as excess body weight. In fact, body mass has been demonstrated to be a major risk factor for symptomatic gallstones. Rapid weight loss can also initiate a prolithogenic state and further increase the likelihood of either gallstone formation or existing gallstones becoming symptomatic; however, sensible weight loss strategies can mitigate this risk. This review discusses the role of excess body weight and the risk of gallstone disease, as well as the options available for the prevention of symptomatic gallstones. Key Messages Healthy weight loss diets combined with regular physical activity can promote successful weight loss and weight maintenance and reduce the risk of gallstones. Should rapid weight loss be required for health reasons or be expected, e.g., after bariatric surgery, prophylactic ursodeoxycholic acid during the period of weight reduction has been demonstrated to reduce the incidence of gallstones formation or symptomatic gallstone occurrence. The recent German guidelines on gallstones recommend simultaneous cholecystectomy during bariatric surgery but only for those with preexisting symptomatic stones.

Abstract
BACKGROUND AND AIMS The association of water intake with type 2 diabetes mellitus (T2DM) is still unclear. Therefore, the aim of this systematic review and meta-analysis was to synthesize the knowledge about the relationship between water intake and the risk of T2DM. METHODS We conducted a systematic search in PubMed and Scopus up to June 2018 for observational studies. Risk ratios (RR)s and 95% confidence intervals (95% CI)s were calculated and fixed effects models were used. RESULTS Overall, 6 studies were included in the meta-analyses. There was an inverse relationship between water intake and risk of T2DM (RR: 0.94; 95% CI: 0.91-0.97, P < 0.001) with low heterogeneity (I2 = 24%, P = 0.24). CONCLUSION Our findings indicated that the intake of water was correlated with reduced risk of type 2 diabetes in women and men. These results support the current recommendations of water intake as an inseparable part of a diet with the lowest risk of diabetes mellitus.

[PMID: 33557387 PMCID: PMC7915548 DOI: 10.3390/nu13020516] [Citation(s) in RCA: 39] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2020] [Revised: 01/28/2021] [Accepted: 01/30/2021] [Indexed: 02/08/2023] Open
Abstract
The consumption of sweet beverages, including sugar-sweetened beverages (SSB), artificial-sweetened beverages (ASB) and fruit juices (FJ), is associated with the risk of different cardiometabolic diseases. It may also be linked to the development of certain types of tumors. We carried out a systematic review and meta-analysis of observational studies aimed at examining the association between sweet beverage intake and cancer risk. Suitable articles published up to June 2020 were sourced through PubMed, Web of Science and SCOPUS databases. Overall, 64 studies were identified, of which 27 were selected for the meta-analysis. This was performed by analyzing the multivariable-adjusted OR, RR or HR of the highest sweet beverage intake categories compared to the lowest one. Random effects showed significant positive association between SSB intake and breast (RR: 1.14, 95% CI: 1.01–1.30) and prostate cancer risk (RR: 1.18, 95% CI: 1.10–1.27) and also between FJs and prostate cancer risk (RR: 1.03, 95% CI: 1.01–1.05). Although the statistically significant threshold was not reached, there tended to be positive associations for the following: SSBs and colorectal and pancreatic cancer risk; FJs and breast, colorectal and pancreatic cancer risk; and ASBs and pancreatic cancer risk. This study recommends limiting sweet beverage consumption. Furthermore, we propose to establish a homogeneous classification of beverages and investigate them separately, to better understand their role in carcinogenesis.

Dietary intake of fiber, whole grains and risk of colorectal cancer: An updated analysis according to food sources, tumor location and molecular subtypes in two large US cohorts. Int J Cancer 2019; 145:3040-3051.

Abstract
Epidemiologic evidence relating fiber intake to colorectal cancer (CRC) remains inconclusive and data are limited on different food sources of fiber and heterogeneity by tumor subsite and molecular profile. We prospectively followed for CRC incidence 90,869 women from the Nurses' Health Study (1980-2012) and 47,924 men from the Health Professionals Follow-up Study (1986-2012), who completed a validated food frequency questionnaire every 4 years. Cox proportional hazards regression was used to examine the associations with CRC risk for total, cereal, fruit and vegetable fiber and whole grains. We also assessed the associations according to tumor subsites (proximal colon, distal colon and rectum) and molecular markers (microsatellite instability, BRAF mutation, CpG island methylator phenotype and KRAS mutation). We documented 3,178 CRC cases during 3,685,903 person-years of follow-up in the NHS and HPFS. Intake of total dietary fiber was not associated with CRC risk after multivariable adjustment in either women (hazard ratio [HR] comparing extreme deciles, 1.17; 95% CI, 0.92-1.48, ptrend = 0.55) or men (HR, 0.90; 95% CI, 0.67-1.21, ptrend = 0.47). Higher intake of cereal fiber and whole grains was associated with lower CRC risk in men with an HR of 0.75 (95% CI, 0.57-1.00) and 0.72 (95% CI, 0.54-0.96), respectively. No heterogeneity was detected by tumor subsite or molecular markers (pheterogeneity > 0.05). Higher intake of total dietary fiber within the range of a typical American diet is unlikely to substantially reduce CRC risk. The potential benefit of cereal fiber and whole grains in men warrants further confirmation.

Abstract
Cholesterol gallstone disease have relationships with various conditions linked with insulin resistance, but also with heart disease, atherosclerosis, and cancer. These associations derive from mechanisms active at a local (i.e. gallbladder, bile) and a systemic level and are involved in inflammation, hormones, nuclear receptors, signaling molecules, epigenetic modulation of gene expression, and gut microbiota. Despite advanced knowledge of these pathways, the available therapeutic options for symptomatic gallstone patients remain limited. Therapy includes oral litholysis by the bile acid ursodeoxycholic acid (UDCA) in a small subgroup of patients at high risk of postdissolution recurrence, or laparoscopic cholecystectomy, which is the therapeutic radical gold standard treatment. Cholecystectomy, however, may not be a neutral event, and potentially generates health problems, including the metabolic syndrome. Areas covered: Several studies on risk factors and pathogenesis of cholesterol gallstone disease, acting at a systemic level have been reviewed through a PubMed search. Authors have focused on primary prevention and novel potential therapeutic strategies. Expert commentary: The ultimate goal appears to target the manageable systemic mechanisms responsible for gallstone occurrence, pointing to primary prevention measures. Changes must target lifestyles, as well as experimenting innovative pharmacological tools in subgroups of patients at high risk of developing gallstones.

Abstract
Cholesterol gallstone disease is a major health problem in Westernized countries and depends on a complex interplay between genetic factors, lifestyle and diet, acting on specific pathogenic mechanisms. Overweigh, obesity, dyslipidemia, insulin resistance and altered cholesterol homeostasis have been linked to increased gallstone occurrence, and several studies point to a number of specific nutrients as risk- or protective factors with respect to gallstone formation in humans. There is a rising interest in the identification of common and modifiable dietetic factors that put the patients at risk of gallstones or that are able to prevent gallstone formation and growth. In particular, dietary models characterized by increased energy intake with highly refined sugars and sweet foods, high fructose intake, low fiber contents, high fat, consumption of fast food and low vitamin C intake increase the risk of gallstone formation. On the other hand, high intake of monounsaturated fats and fiber, olive oil and fish (ω-3 fatty acids) consumption, vegetable protein intake, fruit, coffee, moderate alcohol consumption and vitamin C supplementation exert a protective role. The effect of some confounding factors (e.g., physical activity) cannot be ruled out, but general recommendations about the multiple beneficial effects of diet on cholesterol gallstones must be kept in mind, in particular in groups at high risk of gallstone formation.

Abstract
PURPOSE We aimed to examine the prospective association between dietary glycemic index (GI) and glycemic load (GL) of foods consumed, intakes of carbohydrates and fiber, and the ability to perform activities of daily living (ADL) in older adults. METHODS A total of 844 participants from the Blue Mountains Eye Study aged 60 years or older were examined from 2002-2004 to 2007-2009. Dietary information was collected using a validated, semi-quantitative food-frequency questionnaire. The Older Americans Resources and Services activities of daily living scale were administered to assess the functional status of participants. Multivariable logistic regression analysis was performed. RESULTS After multivariable adjustment, participants who were in the second and third quartiles of energy-adjusted total fiber intake compared to those in the first quartile of intake (reference group) at baseline had reduced risk of incident impaired instrumental activities of daily living (IADL) 5 years later: OR, 0.39 (95% CI 0.22-0.70) and OR 0.54 (95% CI 0.30-0.95), respectively. Analyses that involved dichotomized total fiber intake showed that participants in the upper three quartiles of total fiber intake (> 19 g/day), compared to those in the lowest quartile of intake (≤ 19 g/day) or reference group, had reduced IADL disability risk 5 years later: OR 0.49 (95% CI 0.31-0.79). Non-significant associations were observed with total carbohydrates, GI, and GL and with risk of impaired total and basic ADL at 5-year follow-up. CONCLUSIONS Habitual fiber consumption might be beneficial in leading to improved health status subserving performance of instrumental daily activities, needed to function in the community.

Abstract
BACKGROUND Gallstone disease (GD) belongs to the most frequent disorders in gastroenterology and causes high costs in our health-care systems. Gallstones are uncommon in children but frequent in adults, in particular in women, and are triggered by exogenous risk factors. Here, we summarize the current knowledge concerning the contribution of inherited predisposition to gallstone risk. DESIGN In this review, we present the current data and recent research on the genetics of gallstone disease. RESULTS Several GD-predisposing gene variants have been reported, with most prominent effects being conferred by a common variant (p.D19H) of the hepatic and intestinal cholesterol transporter ABCG5/G8. A smaller group of patients might develop gallstones primarily due low phosphatidylcholine concentrations in bile as a result of loss-of-function mutations of the ABCB4 transporter (low phospholipid-associated cholelithiasis syndrome). Regardless of the origin, the risk factors for gallstones lead to the supersaturation of bile with insoluble compounds, in particular cholesterol. As result, cholesterol stones develop and present the most frequent type of gallstones. Laparoscopic cholecystectomy with low morbidity and mortality is currently the most common and effective method for the therapy of symptomatic gallbladder stones. CONCLUSIONS Gallstone disease represents a multifactorial condition and previous studies have identified the major genetic contributors to gallstone formation. The increasing knowledge about the pathomechanisms of hepatobiliary metabolism and GD as well as the identification of additional risk factors might help to overcome the current invasive therapy by specific lifestyle intervention and precise molecular treatment.

Eur J Nutr 2018; 57:1073-1082. [PMID: 28353070 PMCID: PMC6749615 DOI: 10.1007/s00394-017-1390-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2016] [Accepted: 01/28/2017] [Indexed: 01/10/2023]
Abstract
BACKGROUND High added sugar consumption has been associated with the development of metabolic syndrome (MetS). The American Heart Association (AHA) diet is designed to prevent and treat MetS; however, it remains unclear whether the AHA diet is effective on decreasing added sugar consumption. The aim of our study was to evaluate the effect of the AHA dietary counselling on added sugar consumption among participants with MetS. METHODS The AHA dietary counselling was conducted among 119 participants with MetS from June 2009 to January 2014 (ClinicalTrials.gov: NCT00911885). Unannounced 24-hour recalls were collected at baseline, 3, 6 and 12 months. Added sugar consumption patterns over time were examined using linear mixed models. RESULTS After 1-year dietary counselling, intake of added sugars decreased by 23.8 g/day (95% CI 15.1, 32.4 g/day); intake of nonalcoholic beverages dropped from the leading contributor of added sugar intake to number 7 (from 11.9 to 4.4%); the Alternative Healthy Eating Index (AHEI) score increased by 5.4 (95% CI 2.9, 8.0); however, added sugar intake for 48% participants still exceeded the recommendation. Added sugar intake per meal among different meal type was similar (24.2-25.8%) at baseline. After the 1-year dietary counselling, breakfast became the major resource of added sugar intake (33.3%); the proportion of added sugar intake from snacks decreased from 25.8% (CI 23.1, 28.5%) to 20.9% (CI 19.6, 22.3%). CONCLUSION Although the consumption of added sugars in participants with MetS decreased after the 1-year AHA dietary counselling, added sugar intake from majority of participants still exceeds recommended limits. Actions of successful public health strategies that focus on reducing added sugar intake are needed.

Abstract
Gallstone disease is one of the most common public health problems in the United States. Approximately 10%-20% of the national adult populations currently carry gallstones, and gallstone prevalence is rising. In addition, nearly 750,000 cholecystectomies are performed annually in the United States; direct and indirect costs of gallbladder surgery are estimated to be $6.5 billion. Cholelithiasis is also strongly associated with gallbladder, pancreatic, and colorectal cancer occurrence. Moreover, the National Institutes of Health estimates that almost 3,000 deaths (0.12% of all deaths) per year are attributed to complications of cholelithiasis and gallbladder disease. Although extensive research has tried to identify risk factors for cholelithiasis, several studies indicate that definitive findings still remain elusive. In this review, predisposing factors for cholelithiasis are identified, the pathophysiology of gallstone disease is described, and nonsurgical preventive options are discussed. Understanding the risk factors for cholelithiasis may not only be useful in assisting nurses to provide resources and education for patients who are diagnosed with gallstones, but also in developing novel preventive measures for the disease.

Abstract
AbstractWe aimed to examine the relationship between dietary glycaemic index (GI) and glycaemic load of foods consumed, intakes of carbohydrates, sugars and fibre, and the prevalence of depressive symptoms in older adults. Data collected from 2334 participants aged 55+ years and 1952 participants aged 60+ years were analysed. Dietary information was collected using a semi-quantitative FFQ. Depressive symptoms were based on antidepressant use or either the 36-Item Short-Form Survey, which included the Mental Health Index (MHI), or the Center for Epidemiologic Studies Depression-10 Scale. Participants in the highest v. lowest tertile of dietary GI intake had increased odds of depressive symptoms (assessed by the MHI scale), multivariable-adjusted OR 1·55 (95 % CI 1·12, 2·14). Participants in the highest compared with lowest tertile of fruit consumption had reduced odds of prevalent depressive symptoms, multivariable-adjusted OR 0·66 (95 % CI 0·46, 0·95). Total fibre, vegetable fibre and breads/cereal fibre intakes were all inversely associated with the prevalence of depressive symptoms, with global P values of 0·03, 0·01 and 0·03, respectively. Participants in the second v. first tertile of vegetable consumption had 41 % reduced odds of prevalent depressive symptoms, multivariable-adjusted OR 0·59 (95 % CI 0·40, 0·88). We show that dietary GI and fibre intakes as well as consumption of fruits and vegetables are associated with the prevalence of depressive symptoms.

Abstract
BACKGROUND Sugar-sweetened beverage consumption raises blood glucose concentration and has been positively associated with weight gain and type 2 diabetes, all of which have been implicated in the development of biliary tract cancer (BTC). This study examined the hypothesis that sweetened beverage consumption is positively associated with risk of BTC in a prospective study. METHODS The study population comprised 70 832 Swedish adults (55.9% men, age 45-83 years) from the Swedish Mammography Cohort and Cohort of Swedish Men who were free of cancer and diabetes and completed a food frequency questionnaire at baseline. Incident BTC case patients were ascertained through linkage with the Swedish Cancer Register. Cox proportional hazards regression model was used to analyze the data. All statistical tests were two-sided. RESULTS During a mean follow-up of 13.4 years, 127 extrahepatic BTC case patients (including 71 gallbladder cancers) and 21 intrahepatic BTC case patients were ascertained. After adjustment for other risk factors, women and men in the highest category of combined sugar-sweetened and artificially sweetened beverage consumption had a statistically significantly increased risk of extrahepatic BTC and gallbladder cancer. The multivariable hazard ratios for two or more servings per day (200 mL/serving) of sweetened beverages compared with no consumption were 1.79 (95% confidence interval [CI] = 1.02 to 3.13) for extrahepatic BTC and 2.24 (95% CI = 1.02 to 4.89) for gallbladder cancer. The corresponding hazard ratio for intrahepatic BTC was 1.69 (95% CI = 0.41 to 7.03). CONCLUSIONS These findings support the hypothesis that high consumption of sweetened beverages may increase the risk of BTC, particularly gallbladder cancer.

Abstract
OBJECTIVES Diets that induce a high glycemic response might increase the risk of biliary tract cancer (BTC). We evaluated the hypothesis that diets with high glycemic load (GL) and high glycemic index (GI), which are measures of the glycemic effect of foods, are associated with an increased incidence of BTC. METHODS We used data from a population-based prospective study of 76,014 Swedish adults (age 45-83 years; 57% men) who were free of cancer and had completed a food-frequency questionnaire in the autumn of 1997. Incident cancer cases were ascertained by linkage with the Swedish Cancer Registry. Data were analyzed using Cox proportional hazards regression models. RESULTS During a mean follow-up of 13.3 years (1,010,777 person-years), we identified 140 extrahepatic BTC cases (including 77 gallbladder cancers) and 23 intrahepatic BTC cases. A high dietary GL was associated with an increased risk of BTC. The multivariable relative risks for the highest versus lowest quartile of dietary GL were 1.63 (95% confidence interval (95% CI), 1.01-2.63) for extrahepatic BTC, 2.14 (95% CI, 1.06-4.33) for gallbladder cancer, and 3.46 (95% CI, 1.22-9.84) for intrahepatic BTC. Dietary GI was statistically significantly positively associated with risk of extrahepatic BTC and gallbladder cancer. We observed no statistically significant association between carbohydrate intake and BTC risk, although all associations were positive. CONCLUSION Although these data do not prove a causal relationship, they are consistent with the hypothesis that high-GL and high-GI diets are associated with an increased risk of BTC.

Abstract
OBJECTIVE To evaluate the association between body mass index (BMI, kg/m(2)) and incidence of biliary tract disease. METHODS We performed a systematic review and a meta-analysis of prospective studies by searching the database of PubMed and EMBASE published up to December 31, 2013. Outcome of interest was disease of biliary tract system (gallbladder, extrahepatic bile duct and Ampullar of Vater). We used a random-effects model to combine the study-specific relative risks (RRs) and 95% confidence intervals (95% CIs) from 22 prospective studies. We examined whether BMI was associated with a higher risk of biliary tract disease in a combined analysis. RESULTS The positive association was stronger for non-cancer biliary tract disease than biliary tract cancer; combined RRs (95% CIs) comparing the top with bottom categories were 1.40 (1.15-1.65) for biliary tract cancer and 2.75 (2.35-3.15) for non-cancer biliary tract disease (P for difference<0.001). For non-cancer biliary tract disease, combined RRs (95% CIs) comparing the top with bottom categories were 3.21 (2.48-3.93) for women and 2.01 (1.66-2.37) for men (P for difference=0.04). CONCLUSION Obesity is associated with higher risks of biliary tract cancer and, to a greater extent, non-cancer biliary tract disease.

Abstract
BACKGROUND High carbohydrate intake has been linked to insulin resistance, obesity, and abnormal serum lipid profiles-conditions which favor gallstone formation. GOALS The aim of this study was to evaluate the effect of dietary carbohydrate intake on incident gallbladder disease, defined as biliary sludge and stones, during pregnancy. STUDY We prospectively studied 3070 pregnant women who underwent serial gallbladder ultrasound during pregnancy and at 4 to 6 weeks postpartum. All women had at least 2 study ultrasounds for comparison. A semiquantitative food frequency questionnaire was completed by subjects in the early third trimester. Multivariate logistic regression was performed to assess the risk of incident gallbladder disease across quartiles total and individual carbohydrate and individual carbohydrates (starch, sucrose, galactose, fructose, and lactose) intake. RESULTS The cumulative incidence of gallbladder disease was 10.2% by 4 to 6 weeks postpartum. The risk of incident gallbladder disease during pregnancy was significantly higher among women in the highest quartile of total carbohydrate intake versus those in the lowest quartile (odds ratio 2.09, 95% confidence interval 1.02-4.27). High intake of fructose was associated with increased risk even after additional adjustment for total carbohydrate intake (odds ratio 2.18, 95% confidence interval 1.23-3.86, comparing highest with lowest quartile). No association was found between the intake of starch, sucrose, lactose, or galactose and the risk of incident gallbladder disease. CONCLUSIONS High consumption of total carbohydrate and fructose may increase the risk of developing gallbladder disease during pregnancy. Dietary modification during pregnancy might reduce gallstone incidence during this time period.

Abstract
It is imperative for gastroenterologists to understand the different formations of bile duct stones and the various medical treatments available. To minimize the complications of endoscopic retrograde cholangiopancreatography (ERCP), it is critical to appropriately assess the risk of bile duct stones before intervention. Biliary endoscopists should be comfortable with the basic techniques of stone removal, including sphincterotomy, mechanical lithotripsy, and stent placement. It is important to be aware of advanced options, including laser and electrohydraulic stone fragmentation, and papillary dilatation for problematic cases. The timing and need for ERCP in those who require a cholecystectomy is also a consideration.

Abstract
BACKGROUND Studies in the United States and the United Kingdom have reported an increased risk of cholecystectomy among women exposed to menopausal hormone therapy, but with substantial heterogeneity between types of hormone treatments. We evaluated the risk of cholecystectomy associated with different regimens of menopausal hormone therapy in a large prospective cohort study. METHODS Between 1992 and 2008, 70 928 menopausal women from the French E3N study cohort were sent questionnaires assessing their use of menopausal hormone therapy, medical history and lifestyle characteristics. The primary outcome was cholecystectomy. We analyzed the risk of cholecystectomy associated with use of menopausal hormone therapy using Cox proportional models, with age as time-scale. RESULTS During follow-up, 45 984 (64.8%) of the participants were exposed to menopausal hormone therapy, and 2819 cholecystectomies were recorded. The use of menopausal hormone therapy was associated with an increased risk of cholecystectomy (adjusted hazard ratio [HR] 1.10, 95% confidence interval [CI] 1.01-1.20) compared with women who were not exposed to menopausal hormone therapy. The association was restricted to unopposed oral estrogen therapy (adjusted HR 1.38, 95% CI 1.14-1.67). Over 5 years, about 1 cholecystectomy in excess would be expected in every 150 women using oral estrogen therapy without progestogens, compared with women not exposed to menopausal hormone therapy. INTERPRETATION The risk of cholecystectomy was increased among women exposed to oral estrogen menopausal hormone therapy, especially oral regimens without a progestagen. Complicated gallstone disease should be added to the list of potential adverse events to be considered when balancing the benefits and risks associated with menopausal hormone therapy.

Abstract
Recent criticisms of the glycaemic index (GI) focus on its validity with assertions that GI methodology is not valid, GI values are inaccurate and imprecise, GI does not predict what foods are healthy and that whole grain and fibre are better markers of carbohydrate quality than GI. None of the critics provide sound reasons for rejecting GI because some of their arguments are based on flagrant errors in understanding and interpretation while others are not supported by current data or are inconsistent with other nutritional recommendations. This paper addresses current criticisms of GI and outlines reasons why GI is valid: (1) GI methodology is accurate and precise enough for practical use; (2) GI is a property of foods; and (3) GI is biologically meaningful and relevant to virtually everyone. Current dietary guidelines recommend increased consumption of whole grains and dietary fibre but do not mention GI. However, this is illogical because the evidence that GI affects health outcomes is at least as good or better than that for whole grains and fibre. GI is a novel concept from a regulatory point of view and a number of problems need to be addressed to successfully translate GI knowledge into practice. The problems are not insurmountable but no progress can be made until bias and misunderstanding about GI can be overcome and there is better agreement about what is the actual state of knowledge on GI so that the real issues can be identified and addressed.

Abstract
BACKGROUND Higher intake of carbohydrates and high-glycemic index (high-GI) diets could lead to small vessel dysfunction. OBJECTIVES We aimed to assess the associations between intakes of high-GI and high-glycemic load (high-GL) diets, carbohydrate, and the main carbohydrate-containing food groups and retinal microvascular changes in preadolescents. DESIGN Students aged 12 y (n = 2353) from a random cluster sample of 21 schools underwent detailed eye examinations. Retinal vessel caliber and fractal dimension were measured from digital retinal images. A validated semiquantitative food-frequency questionnaire was administered. RESULTS After multivariable adjustment, children who consumed soft drinks once or more per day had significantly narrower mean retinal arterioles (∼1.9 μm) than did those who never or rarely consumed soft drinks (P-trend = 0.03). When the highest to lowest tertiles of carbohydrate consumption were compared, girls had significantly narrower retinal arterioles (∼1.4 μm; P-trend = 0.03) and boys had wider venules (∼2.3 μm; P-trend = 0.02). In girls only, a higher-GI diet was associated with narrower retinal arterioles (0.98-μm narrowing of retinal arteriolar caliber per SD increase in GI, P = 0.01). Carbohydrate intake and a high-GL diet were associated with greater retinal fractal dimension in girls (highest compared with lowest tertiles: P-trend = 0.003 and 0.01, respectively). CONCLUSIONS Greater consumption of carbohydrates and soft drinks was associated with retinal arteriolar narrowing and venular widening. Because these microvascular signs have been shown to be markers of future cardiovascular disease risk, the presence of this risk factor in children could support the need for healthy dietary patterns that include lower consumption of high-GI foods and soft drinks.

Abstract
The term glycaemic-index (GI) originally appeared in the literature in the early 1980s. GI categorizes carbohydrate according to glycaemic effect postprandially. Since its inception, GI has obtained and maintained interest of academics and clinicians globally. Upon review of GI literature, it becomes clear that the clinical utility of GI is a source of controversy. Can and should GI be applied clinically? There are academics and clinicians on both sides of the argument. Certainly, this controversy has been a stimulus for the evolution of GI methodology and application research, but may also negatively impact clinicians' perception of GI if misunderstood. This article reviews two assessments of GI that are often listed as barriers to application; the GI concept is (1) too complex and (2) too difficult for clients to apply. The literature reviewed does not support the majority of purported barriers, but does indicate that there is a call from clinicians for more and improved GI education tools and clinician GI education. The literature indicates that the Registered Dietitian (RD) can play a key role in GI knowledge translation; from research to application. Research is warranted to assess GI education tool and knowledge needs of clinicians and the clients they serve.

Abstract
It has been shown that dietary glycemic index (GI) and fiber could have a role in the development of chronic diseases; however, the link between carbohydrate nutrition and development of chronic kidney disease (CKD) is unclear. We aimed to determine whether cross-sectional and longitudinal associations exist between carbohydrate nutrition (mean dietary GI, dietary intakes of carbohydrate, sugar, starch, and fiber) and CKD. Data included 2600 Blue Mountains Eye Study (1997-1999) participants aged ≥50 y. Baseline biochemistry including serum creatinine was measured. Moderate CKD was defined as estimated glomerular filtration rate (eGFR) < 60 mL·min(-1)·1.73 m(-2). Dietary data were collected in a semiquantitative FFQ. Cross-sectionally, participants in the 4th quartile of mean dietary GI intake compared with those in the first quartile (reference) had a 55% increased likelihood of having eGFR < 60 mL·min(-1)·1.73 m(-2) [multivariable-adjusted OR = 1.55 (95% CI = 1.07-2.26); P-trend = 0.01]. After multivariable adjustment, participants in the 4th quartile of dietary cereal fiber intake compared with those in the first quartile (reference) had a 50% reduced risk of incident moderate CKD (P-trend = 0.03). Higher baseline consumption of energy-dense, nutrient-poor sources of carbohydrate (e.g. cookies) yielded a 3-fold higher risk of incident CKD (P-trend = 0.01). In summary, we observed a novel link between high cereal fiber intake and reduced incidence of moderate CKD and this was supported by the cross-sectional association with dietary GI. Conversely, our data suggest that higher intake of energy-dense, nutrient-poor sources of carbohydrate, potentially through acute hyperglycemia, could impair renal function.

Abstract
Age-related hearing loss is a frequent disability in older adults and nutrition could play a role in the development of this condition. Carbohydrate nutrition [including dietary glycemic index (GI) and load (GL)] may be linked to hearing loss. We aimed to determine the association between carbohydrate nutrition (including mean dietary GI and GL, and the dietary intakes of carbohydrate and sugar), starch, cereal and total fiber, and age-related hearing loss. The Blue Mountains Hearing Study is a population-based survey of age-related hearing loss (1997-1999 to 2002-2004). Hearing loss was measured in 2956 participants (aged ≥50 y) and was defined as the pure-tone average of frequencies 0.5, 1.0, 2.0, and 4.0 kHz > 25 dB hearing level. Dietary data were collected in a semiquantitative FFQ. A purpose-built database based on Australian GI values was used to calculate the mean GI. A higher mean dietary GI was associated with an increased prevalence of any hearing loss, comparing quintiles 1 (lowest) and 5 (highest), [multivariable-adjusted odds ratio = 1.41 (95% CI = 1.01-1.97)]. Participants in the highest quartile of mean dietary GL intake compared with those in the lowest quartile had a 76% greater risk of developing incident hearing loss (P-trend = 0.04). Higher carbohydrate and sugar intakes were associated with incident hearing loss (P-trend = 0.03 and P-trend = 0.05, respectively). In summary, a high-GL diet was a predictor of incident hearing loss, as was higher intake of total carbohydrate. Hence, high postprandial glycemia might be a potential underlying biological mechanism in the development of age-related hearing loss.

Abstract
OBJECTIVE Consumption of sugar-sweetened beverages (SSBs), which include soft drinks, fruit drinks, iced tea, and energy and vitamin water drinks has risen across the globe. Regular consumption of SSBs has been associated with weight gain and risk of overweight and obesity, but the role of SSBs in the development of related chronic metabolic diseases, such as metabolic syndrome and type 2 diabetes, has not been quantitatively reviewed. RESEARCH DESIGN AND METHODS We searched the MEDLINE database up to May 2010 for prospective cohort studies of SSB intake and risk of metabolic syndrome and type 2 diabetes. We identified 11 studies (three for metabolic syndrome and eight for type 2 diabetes) for inclusion in a random-effects meta-analysis comparing SSB intake in the highest to lowest quantiles in relation to risk of metabolic syndrome and type 2 diabetes. RESULTS Based on data from these studies, including 310,819 participants and 15,043 cases of type 2 diabetes, individuals in the highest quantile of SSB intake (most often 1-2 servings/day) had a 26% greater risk of developing type 2 diabetes than those in the lowest quantile (none or <1 serving/month) (relative risk [RR] 1.26 [95% CI 1.12-1.41]). Among studies evaluating metabolic syndrome, including 19,431 participants and 5,803 cases, the pooled RR was 1.20 [1.02-1.42]. CONCLUSIONS In addition to weight gain, higher consumption of SSBs is associated with development of metabolic syndrome and type 2 diabetes. These data provide empirical evidence that intake of SSBs should be limited to reduce obesity-related risk of chronic metabolic diseases.

Abstract
Gallstones are common in Western countries and due to pain and complications pose a substantial burden on health care systems. In general, cholesterol gallstones are distinguished from bilirubin gallstones. Bilirubin gallstones form if the ion product of unconjugated bilirubin and calcium in gallbladder bile exceeds the solubilisation capacities of mixed micelles and vesicles. Cholesterol gallstones develop if the amount of cholesterol in gallbladder bile exceeds the maximum concentration that is soluble at the given concentration of bile salts and phospholipids. In addition, cholesterol gallstone formation requires hypomotility of the gallbladder and a mucin gel as nucleation matrix for monohydrate crystals. The individual risk of gallstone formation is determined by interactions of lithogenic alleles of gallstone susceptibility genes and multiple environmental factors. For asymptomatic gallstones, expectant management is recommended, whereas an episode of gallstone-associated pain substantially increases the risk of complications such as cholecystitis, cholangitis and pancreatitis and therefore necessitates cholecystectomy.

Abstract
In recent decades, temporal patterns in SSB intake have shown a close parallel between the upsurge in obesity and rising levels of SSB consumption. SSBs are beverages that contain added caloric sweeteners such as sucrose, high-fructose corn syrup or fruit-juice concentrates, all of which result in similar metabolic effects. They include the full spectrum of soft drinks, carbonated soft drinks, fruitades, fruit drinks, sports drinks, energy and vitamin water drinks, sweetened iced tea, cordial, squashes, and lemonade, which collectively are the largest contributor to added sugar intake in the US. It has long been suspected that SSBs have an etiologic role in the obesity epidemic, however only recently have large epidemiological studies been able to quantify the relationship between SSB consumption and long-term weight gain, type 2 diabetes (T2DM) and cardiovascular disease (CVD) risk. Experimental studies have provided important insight into potential underlying biological mechanisms. It is thought that SSBs contribute to weight gain in part by incomplete compensation for energy at subsequent meals following intake of liquid calories. They may also increase risk of T2DM and CVD as a contributor to a high dietary glycemic load leading to inflammation, insulin resistance and impaired beta-cell function. Additional metabolic effects from the fructose fraction of these beverages may also promote accumulation of visceral adiposity, and increased hepatic de novo lipogenesis, and hypertension due to hyperuricemia. Consumption of SSBs should therefore be replaced by healthy alternatives such as water, to reduce risk of obesity and chronic diseases.

Abstract
Obesity has become an epidemic worldwide. It is accompanied by a multitude of medical complications including metabolic syndrome. Obesity may lead to fatty infiltration of multiple internal organs including liver, heart, kidney, and pancreas, causing organ dysfunctions. Fatty infiltration leads to chronic inflammation and tissue damage. Fatty infiltration in the liver results in nonalcoholic fatty liver disease, which is increasingly common nowadays. Recent studies in animals and humans indicate that obesity also is associated with fatty infiltration of gallbladder, resulting in cholecystosteatosis. The increased gallbladder lipids include free fatty acids, phospholipids, and triglycerides. Enhanced inflammation with an increased amount of fat in the gallbladder results in an abnormal wall structure and decreased contractility. In support of this notion, a recent experiment on the effect of Ezetimibe, which is a novel drug that inhibits intestinal fat absorption, on fatty gallbladder disease reveals that Ezetimibe can ameliorate cholecystosteatosis and restore in vivo gallbladder contractility. The proportion of cholecystectomies performed for chronic acalculous cholecystitis has increased significantly over the past two decades. An increase in gallbladder fat, which leads to poor gallbladder emptying and biliary symptoms, may partly explain this phenomenon. Although dietary carbohydrates have been demonstrated to be associated with fatty gallbladder disease, other potential modifiable environmental factors are not clear. The pathogenesis and prognosis of fatty gallbladder disease, including steatocholecystitis, and the relations of fatty gallbladder disease to nonalcoholic fatty liver disease, including steatohepatitis, and other components of metabolic syndrome are largely unknown. More research is needed to answer these questions.

Abstract
Background Our study aimed to assess the nationwide trends in the incidence of severe gallstone disease in Taiwan among adults aged ≥20. Methods A retrospective longitudinal study was conducted using Taiwan National Health Insurance Research Database collected during 1997–2005. Patients with incident severe gallstone disease (acute cholecystitis, biliary pancreatitis, acute cholangitis) and gallstone-related procedures (elective and non-elective cholecystectomy, endoscopic retrograde cholangiopancreatography [ERCP]) that led to hospital admission were identified using ICD-9-CM diagnostic and procedure codes. Annual incidence rates of gallstone-related complications and procedures were calculated and their 95% confidence intervals (CI) were estimated assuming a Poisson distribution. Results The hospital admission rate for severe gallstone disease increased with advancing age and the age-standardized rate (95% CI) per 1000 population was 0.60 (0.59–0.60) for men and 0.59 (0.59–0.60) for women. Men had a higher rate of acute cholecystitis, probably due to the substantially lower rate of elective cholecystectomy among men than women. For those aged 20–39, hospital admissions for all gallstone-related complications and procedures increased significantly. For those aged ≥60, incidences of biliary pancreatitis, acute cholangitis, and hospital admission for gallstone receiving ERCP increased significantly without substantial change in the incidence of acute cholecystitis and despite a decreased rate of elective cholecystectomy. Conclusion This population-based study found a substantial increase in the rate of admission for severe gallstone disease among those aged 20–39. Concurrently, the incidences of biliary pancreatitis and acute cholangitis have risen among those aged ≥60.

Abstract
BACKGROUND & AIMS Statins can reduce biliary cholesterol secretion independently of their ability to inhibit cholesterol synthesis. Statins also prevent the formation of gallstones in animal studies, although the effect of statins on human gallstone disease has been controversial. METHODS We examined the relationship between the use of statins and the risk of cholecystectomy in a cohort of US women. As part of the prospective Nurses' Health Study, participants biennially reported their history of gallstone disease and whether they had undergone cholecystectomy. Women also reported lifetime use of statins retrospectively in 2000. We conducted a retrospective analysis of statin using data collected in 2000, to define use from 1994 forward, and a prospective analysis for general lipid-lowering drugs from 1994 to 2004. RESULTS In the statin analysis we ascertained 2479 cases of cholecystectomy during 305,197 person-years of follow-up evaluation. The multivariate relative risk for current statin users, compared with nonusers, was 0.82 (95% confidence interval, 0.70-0.96). In the analysis of general cholesterol-lowering drugs, we ascertained 3420 cases of cholecystectomy during 511,411 person-years of follow-up evaluation. Compared with nonusers, the multivariate relative risk for current users of general cholesterol-lowering drugs, mostly statins in this cohort, was 0.88 (95% confidence interval, 0.79-0.98). CONCLUSIONS Statin use appears to reduce the risk of cholecystectomy in women.

Abstract
The number of gallstone patients is increasing in ageing populations with a high prevalence of metabolic syndrome and obesity. Recently variants of hepatic ATP binding cassette transporters have been identified as genetic susceptibility factors for gallstone disease, pointing to novel means for risk assessment and prevention. Although laparoscopic cholecystectomy is the mainstay of therapy for symptomatic gallbladder stones, the clinical management of gallstone disease is changing rapidly, with an increase in day case surgery and the advent of transluminal endoscopic surgery. Here, we summarize the molecular and genetic mechanisms of gallstone formation as well as the current evidence-based algorithms for diagnosis and therapy of gallbladder and bile duct stones.

Abstract
There is growing evidence that gallstone formation may be genetically determined. Cholesterol 7alpha-hydrolase (CYP7A1) is an enzyme that catalyzes the first, rate-limiting reaction of cholesterol catabolic pathway. Recently, a common c.-278A>C polymorphism (rs3808607:G>T) has been described in CYP7A1 gene, associated with altered plasma lipid levels. The aim of this study was to verify the finding that CYP7A1 polymorphism may be associated with gallstone disease. Frequency and distribution of the studied alleles did not differ significantly between the patients (-278C; minor allele frequency: 0.45) and the controls (0.48). No significant gender-related differences of allele frequencies or distribution were noted. We conclude that CYP7A1 promoter polymorphism is not a valuable marker of gallstone disease susceptibility in a Polish population.

Abstract
AbstractObjectiveTo assess the ability of a food-frequency questionnaire (FFQ) to rank Australians according to their intake of total carbohydrate, sugar, starch, fibre, glycaemic index (GI) and glycaemic load (GL).DesignCross-sectional sample from a population cohort.SettingTwo postcode areas west of Sydney, Australia.SubjectsFrom 1992 to 1994, a total of 2868 older Australians provided dietary data using a 145-item Willett-derived FFQ. A representative sub-sample of 78 subjects completed three 4-day weighed food records (WFRs). Pearson and Spearman correlations, Bland–Altman plots and weighted kappa values were calculated.ResultsCompared with the WFR, the FFQ provided higher mean estimates of all nutrients except starch and GI. All Pearson and/or Spearman correlations were greater than 0.5, except for GL. For GI, sugar, starch and fibre, the regression lines from the Bland–Altman analysis indicated a non-significant linear trend (P = 0.07, P = 0.36, P = 0.28 and P = 0.10, respectively). For GL and total carbohydrate, however, there was a significant linear trend (P = 0.006 and P < 0.0001, respectively), indicating that as the GL and carbohydrate intake of individuals increased, so did the magnitude of the error between the FFQ and WFR. Weighted kappa values all indicated moderate to good agreement, with the exception of GL which was only fair. The proportions of subjects correctly classified within one quintile for all of the nutrients were over 50% and gross misclassification was low (<10%).ConclusionThis FFQ was able to rank individuals according to their intakes of total carbohydrate, sugar, starch, fibre and GI, but not as well for GL.

Abstract
BACKGROUND Inconsistent findings from observational studies have prolonged the controversy over the effects of dietary glycemic index (GI) and glycemic load (GL) on the risk of certain chronic diseases. OBJECTIVE The objective was to evaluate the association between GI, GL, and chronic disease risk with the use of meta-analysis techniques. DESIGN A systematic review of published reports identified a total of 37 prospective cohort studies of GI and GL and chronic disease risk. Studies were stratified further according to the validity of the tools used to assess dietary intake. Rate ratios (RRs) were estimated in a Cox proportional hazards model and combined by using a random-effects model. RESULTS From 4 to 20 y of follow-up across studies, a total of 40 129 incident cases were identified. For the comparison between the highest and lowest quantiles of GI and GL, significant positive associations were found in fully adjusted models of validated studies for type 2 diabetes (GI RR = 1.40, 95% CI: 1.23, 1.59; GL RR = 1.27, 95% CI: 1.12, 1.45), coronary heart disease (GI RR = 1.25, 95% CI: 1.00, 1.56), gallbladder disease (GI RR = 1.26, 95% CI: 1.13, 1.40; GL RR = 1.41, 95% CI: 1.25, 1.60), breast cancer (GI RR = 1.08, 95% CI: 1.02, 1.16), and all diseases combined (GI RR = 1.14, 95% CI: 1.09, 1.19; GL RR = 1.09, 95% CI: 1.04, 1.15). CONCLUSIONS Low-GI and/or low-GL diets are independently associated with a reduced risk of certain chronic diseases. In diabetes and heart disease, the protection is comparable with that seen for whole grain and high fiber intakes. The findings support the hypothesis that higher postprandial glycemia is a universal mechanism for disease progression.

Abstract
BACKGROUND There is growing evidence that gallstone formation may be genetically determined. It was recently presented that a common polymorphism in the LRPAP1 gene might be associated with gallstone disease. AIM Since reproducibility of data is important in genetic association studies, a case control study was designed to find out whether LRPAP1 gene polymorphism is associated with gallstone disease in a Polish population. SUBJECTS Two hundred eighty-nine Polish Caucasian gallstone disease patients and 251 healthy controls participated in the study. METHODS A 37-bp insertion/deletion polymorphism in intron 5 of LRPAP1 (rs11267919) was determined by means of polymerase chain reaction assay. RESULTS The frequencies and distribution of the insertion/deletion alleles did not differ significantly between gallstone disease patients and controls. No significant gender-related differences in allele frequencies or distributions were noted. CONCLUSION The LRPAP1 insertion/deletion polymorphism is not associated with gallstone disease in a Polish population.

Abstract
INTRODUCTION We have recently demonstrated that obese and lean mice fed a high fat diet have increased gallbladder wall fat and decreased gallbladder contractility, cholecystosteatosis. Animal and human data also suggest that diets high in refined carbohydrates lead to gallstone formation. However, no data are available on the role of dietary carbohydrates on gallbladder wall fat and inflammation. Therefore, we tested the hypothesis that both obesity and dietary carbohydrates would increase gallbladder fat and cytokines, steatocholecystitis. METHODS At 8 wk of age, 47 lean and 22 obese female mice were fed a 45% carbohydrate (CHO) diet while an equal number of lean and obese mice were fed a 75% CHO diet for 4 wk. All mice underwent cholecystectomy, and the gallbladders were snap-frozen. Individual and total lipids were measured by gas chromatography. Interleukin (IL)-1beta, tumor necrosis factor (TNF)-alpha, and IL-6 were measured by enzyme-linked immunosorbent assay. Data were analyzed by analysis of variance and Tukey test. RESULTS Gallbladder total fat, triglycerides, and cholesterol were maximum (P < 0.001) in obese mice on the 75% CHO diet. Gallbladder TNF-alpha and IL-1beta as well as serum cholesterol levels showed a similar pattern (P < 0.001). Gallbladder saturated free fatty acids and IL-6 levels were highest (P < 0.001) in obese mice on the 45% CHO diet. CONCLUSIONS These data suggest that (1) both obesity and dietary carbohydrates increase gallbladder total fat, triglycerides, cholesterol, TNF-alpha, and IL-1beta and (2) obesity also increases gallbladder free fatty acids and IL-6. Therefore, we conclude that obesity is associated with steatocholecystitis and that a high carbohydrate diet exacerbates this phenomenon.

Susceptibility to obesity and gallbladder stasis produced by a protein- and fat-enriched diet in male mice compared with female mice. Nutr Metab (Lond) 2007; 4:14.

Abstract
BACKGROUND The frequency of Japanese subjects over 20 years old with metabolic syndrome is 45.6% in men but just 16.7% in women. The reason why Japanese male subjects are more susceptible to metabolic syndrome than women is unknown. One possibility is the higher frequency of Japanese male subjects (40-70 years old) who had a drinking habit (67%), while that of female subjects was only 25%. In addition, daily fat intake was markedly increased in Japanese subjects (from 9% to 25%), and cholesterol cholelithiasis is one of the most rapidly increasing digestive diseases during the past 50 years. The object of this study is to examine whether a potential sex-related risk factor exists in the manifestation of metabolic syndrome as well as gallstone formation. METHODS Gallbladder dysmotility accerelates gallstone formation and gallbladder contraction depends on cholecystokinin (CCK) and its receptor (CCK-1R). We developed CCK-1R gene knockout (-/-) mice. The effects of the fat- and protein- enriched diet OA-2 on body weight, hyperlipidemia, and frequencies of sludge and gallstone formation were examined, and compared between wild-type and CCK-1R(-/-) male and female mice. The OA-2 diet contains slightly higher protein and fat (7.9 % fat and 27.6 % protein) compared with a standard diet (CRF-1) (5.6 % fat and 22.6 % protein), but their total energies are similar. After weaning, CRF-1 was provided until 3 months of age in all animals. Administration of an OA-2 diet was started when age-matched CCK-1R(-/-) and wild-type male and female mice reached maturity, at 3 months of age. Administration of CRF-1 was continued in the rest of the animals. Mice were sacrificed by guillotine at 6 and 12 months of age and the blood was collected to measure plasma levels of triglyceride and cholesterol. The gallbladder was removed and classified as normal (clear gallbladder), clouded (sludge formation), and/or containing gallstone formations. RESULTS As long as CRF-1 was provided, the frequency of sludge and/or gallstone formation in CCK-1R(-/-) male mice was 3 of 8 (35%) and 4 of 9 (45%) in females at 12 months of age, whereas no gallstone formation was observed at 6 months of age. On the other hand, male mice fed OA-2 increased their body weight and plasma lipid concentrations, compared with those fed CRF-1 regardless of genotype. Under the OA-2 diet, sludge and gallstone formation was observed at 6 months of age, not only in CCK-1R(-/-) male mice but also in wild-type male mice. In contrast, parameters in female mice did not differ between the two diets. CONCLUSION Male mice were more susceptible to protein- and fat-enriched diet-induced obesity than female mice, and hyper-nutritional status accelerated sludge and gallstone formation in male mice.

Abstract
Gallstone disease is one of the most prevalent gastrointestinal diseases with a substantial burden to health care systems that is supposed to increase in ageing populations at risk. Aetiology and pathogenesis of cholesterol gallstones still are not well defined, and strategies for prevention and efficient nonsurgical therapies are missing. This review summarizes current concepts on the pathogenesis of cholesterol gallstones with focus on the uptake and secretion of biliary lipids and special emphasis on recent studies into the genetic background.

Abstract
BACKGROUND Gallbladder dysmotility accelerates cholelithiasis. In turn, gallbladder dysmotility can occur secondary to inflammation and excess cholesterol accumulation in gallbladder smooth muscle. METHODS The present study was designed to determine how much gallbladder dysmotility contributes to gallstone formation as a primary cause and whether a sex difference exists in gallstone formation by comparing cholecystokinin-1 receptor gene-deficient [CCK-1R(-/-)] male and female mice. RESULTS No sludge or gallstone formation was observed in mice at 6 months of age. The frequency of sludge and gallstone formation in mice at 12 and 24 months of age was slightly higher in female CCK-1R(-/-) mice than in males, but the difference was not significant. CONCLUSIONS Gallbladder dysmotility may have accelerated sludge and gallstone formation, but its contribution was limited. A 12-month period was required to produce gallstones, and after the mice reached 12 months of age, further ageing did not increase the frequency of gallstones. The effect of sex did not reach a significant level.

Abstract
Cholelithiasis is one of the most prevalent gastroenterological diseases, precipitated mainly by environmental factors. However, twin studies provided strong evidence for a role of genetic factors in the disease pathogenesis. An association between plasma lipoprotein levels and gallstone disease (GSD) was presented. Apolipoprotein B is an essential structural component of triglyceride-rich lipoprotein particles and plays an important role in the maintenance of cholesterol homeostasis in mammals. Various studies have shown a relationship between APOB gene polymorphisms and lipoprotein levels, but only few investigated a potential association between APOB polymorphism and GSD, giving contrary results. In the current study, an association between common polymorphisms in APOB gene (T2488T and E4154K) and cholesterol gallstone disease was examined. Two hundred and forty patients of Caucasian origin suffering from cholelithiasis, as well as 217 healthy individuals, were included in the study. Patients were genotyped for two single nucleotide polymorphisms (SNPs) in APOB gene: 2488C>T (XbaI), and 4154G>A (EcoRI) using PCR-RLFP method. The resulting analysis has shown that polymorphic loci in positions 2488 and 4154 in APOB gene are in full linkage in a Polish population and form only three haplotypes: 2488C-4154G, 2488T-4154G and 2488C-4154A. Frequency and distribution of 2488C>T alleles did not differ significantly between patients and controls. The 4154G allele has been found to be associated with GSD (p=0.001). A risk of gallstone formation was reduced in 4154AA homozygotes (OR=0.25, p=0.009) and heterozygous individuals (OR=0.63, p=0.03) as compared to 4154GG homozygotes. Additionally, 2488C-4154A haplotype was identified as a protective factor against GSD (p=0.04). Our results suggest that SNPs in APOB, potentially considered as one of lith genes as well as certain haplotypes, may be risk factors for GSD.

Abstract
BACKGROUND Animal and human data suggest that a diet high in refined carbohydrates leads to gallstone formation. However, no data are available on the role of dietary carbohydrates on gallbladder volume or on cholesterol crystal formation. Therefore, we tested the hypothesis that a high carbohydrate diet would alter gallbladder volume and enhance cholesterol crystal formation. METHODS At 8 weeks of age, 60 lean and 36 obese leptin-deficient female mice were fed a 45% carbohydrate diet while an equal number of lean and obese mice were fed a 75% carbohydrate diet for 4 weeks. All animals then underwent cholecystectomy, and gallbladder bile volume was recorded. Bile was pooled, filtered, and maintained in a water bath at 37 degrees C for 14 days. Birefringent cholesterol crystals in bile were counted daily; crystal observation time and crystal mass were determined. RESULTS The crystal observation time was significantly shortened in both lean and obese mice on the 75% diet compared with their counterparts on the 45% diet. The crystal mass was significantly increased in the lean mice on the 75% diet compared with the 45% diet. Gallbladder volumes were significantly reduced in both lean and obese mice on the 75% diet compared with their counterparts on the 45% diet. CONCLUSIONS These data suggest that a high carbohydrate diet decreases gallbladder volume, shortens cholesterol crystal observation time, and increases crystal mass. We conclude that dietary carbohydrates may play a role in cholesterol gallstone formation by altering biliary motility and by enhancing crystal formation.

Abstract
BACKGROUND There is a high prevalence of gallstone disease in Western countries as a consequence of genetic, biochemical, and environmental factors. Animal and clinical studies have explored the importance of dietary elements. Overwhelming but conflicting information has been reported about the relationship between specific dietary components and gallstone disease. Although the detailed biochemical pathways have been described in experimental models, human studies are mainly epidemiological. METHODS We performed a Medline search with the terms "diet", "gallstones", "cholesterol", "risk factors", including results from 1965 to 2006 and the author's personal library to review the relationship between dietary factors and cholesterol gallstone disease. RESULTS We identified over 150 references and present their results with respect to the author's criteria. CONCLUSIONS The best delineated relationship between cholesterol gallstones and diet was found in the studies that analyzed total calorie intake, refined sugars and fiber. The possible mechanisms are discussed in base of experimental studies.

Abstract
BACKGROUND Gallstone disease has been regarded as an obesity-related disease. Therefore, we hypothesized that leptin and adiponectin, mainly produced by adipose tissue, may play roles in gallstone disease. PATIENTS AND METHODS The RIA method was used to analyze serum leptin and adiponectin levels of 90 gallstone patients and 91 healthy subjects. RESULTS Our results showed that BMI, fasting glucose, serum AST and ALT, and leptin were significantly increased in the gallstone patients as compared with the healthy subjects (P < 0.001, P < 0.001, P < 0.001, P < 0.001, P < 0.001, and P = 0.013, respectively). Intriguingly, serum adiponectin was the only variable to be significantly decreased in the gallstone patients (P = 0.002). Furthermore, serum AST, leptin, and adiponectin were significantly associated with gallstone disease (P < 0.001, P = 0.021, and P = 0.006, respectively). Overweight (BMI >or= 25 kg m(-2)), but not normal-weight, gallstone patients had an increased serum leptin and a decreased serum adiponectin level as compared with matched healthy subjects (P < 0.001 and P = 0.024, respectively). In addition, serum leptin was positively correlated with BMI and serum cholesterol, while serum adiponectin was inversely correlated with serum triglyceride in the gallstone patients. CONCLUSIONS Our study indicated that hyperleptinaemia and hypoadiponectinaemia might be involved in the occurrence of gallstone disease. However, the causal relationship of hyperleptinaemia and hypoadiponectinaemia with gallstone disease might require further investigation.

Abstract
Cholelithiasis is one of the most prevalent gastroenterological diseases, imposing a huge economic burden on health-care systems. Gallbladder stones form when the concentration of cholesterol or bilirubin exceeds the solubility in the bile salt and phospholipid-rich bile. The physiology of biliary lipid secretion by a number of specialized transport proteins has recently been elucidated, and underlying genetic defects in these proteins have been identified as susceptibility factors for gallstone disease. Recent studies of identical twins and family strongly support the idea of a genetic component to gallstone disease. Epidemiological studies in high-risk populations indicate that gallstone formation is caused by multiple environmental influences and common genetic factors and their interactions. Monogenic subtypes of cholelithiasis, such as biliary lipid transporter deficiencies, appear to be rare. The characterization of lithogenic genes in knockout and transgenic mice, and the identification of many gallstone susceptibility loci in inbred mice, provide the basis for studies of the corresponding genes in patients with gallstones. The transfer of findings from mouse genetics to the bedside might lead to new strategies for individual risk assessment and reveal molecular targets for the development of new treatment strategies.
