Gender and metabolic differences of gallstone diseases

AIM： To investigate the risk factors for gallstone disease in the general population of Chengdu, China. METHODS： This study was conducted at the West China Hospital. Subjects who received a physical examination at this hospital between January and December 2007 were included. Body mass index, blood pressure, fasting plasma glucose, serum lipid and lipoproteins concentrations were analyzed. Gallstone disease was diagnosed by ultrasound or on the basis of a history of cholecystectomy because of gallstone disease. Unconditional logistic regression analysis was used to investigate the risk factors for gallstone disease, and the Chi-square test was used to analyze differences in the incidence of metabolic disorders between subjects with and without gallstone disease. RESULTS： A total of 3573 people were included, 10.7% （384/3573） of whom had gallstone diseases. Multiple logistic regression analysis indicated that the incidence of gallstone disease in subjects aged 40-64 or ≥65 years was significantly different from that in those aged 18-39 years （P 〈 0.05）; the incidence was higher in women than in men （P 〈 0.05）. In men,a high level of fasting plasma glucose was obvious in gallstone disease （P 〈 0.05）, and in women, hypertriglyceridemia or obesity were significant in gallstone disease （P 〈 0.05）. CONCLUSION： We assume that age and sex are profoundly associated with the incidence of gallstone disease; the metabolic risk factors for gallstone disease were different between men and women.

Non-occupational lead exposure and hypertension in Pakistani adults

Hypertension is one of the most prevalent diseases in the developed and developing countries. Based on the long historical association and the provocative findings of blood pressure effects at low level of lead exposure a study was carried out to determine if an association existed between low blood lead concentration and hypertension. In this study the effects of low-level exposure to lead on blood pressure were examined among 244 adults using atomic absorption spectrometer. For quality assurance purpose certified reference materials i.e., Animal blood A-13, Bovine liver 1577 and cotton cellulose V-9 from IAEA （International Atomic Energy Agency） and NIST （National Institute of Standard Technology） were analyzed under identical experimental conditions. The mean age of hypertensive adults was 52 years （range 43-66）. The mean values of systolic and diastolic blood pressure were （209±11.7） （range 170-250） and （117±3.9） （range 105-140） mmHg respectively. Blood lead concentration ranged from 78-201 μg/L with a mean of 139 μg/L and 165-497 μg/L with a mean of 255 μg/k in normal and hypertensive adults respectively. Increase in systolic blood pressure was significantly predictive with increase in blood lead levels. Body mass index （BMI） and lipid profile including total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol and triglyceride correlated with blood pressure.

Residual urinary output in high body mass index individuals on chronic hemodialysis:A disregarded life vest?

AIM： To assess residual diuresis and diverse variables according to body mass index （BMI）.METHODS： Cross-sectional study （n = 57）, with 3 groups. Group A： BMI 〈 25, n = 22; Group B： BMI 25-30, n = 15; Group C： BMI 〉 30, n = 20. Diuresis, hematocrit, albumin, C-reactive protein, Malnutrition infammatory score, Pro-BNP, Troponin T, leptin and in-sulin levels are expressed as median and ranges （r）. RESULTS： Albumin （g/dL）： GA vs GC, 3.70 （r2.20-4.90） vs 3.85 （r3.40-4.90）, P = 0.02. Diuresis （mL/d）： GA 690 （r0-1780）; GB 660 （r60-1800）; GC 840 （r40-2840）. Diuresis GA vs GC, P = 0.01. Leptin （ng/mL）： GA vs GC, 3.81 （r0.78-69.60） vs GC, 32.80 （r0.78-124.50）, P 〈 0.001. Insulin （μU/mL）： GA vs GB, 7 （r2-44） vs 11.50 （r4-38）, P = 0.02; GA vs GC, 7 （r2-44） vs 19.5 （r5-155）, P = 0.0001. Troponin T and Pro-BNP levels were not different. Significant correlations： GC, Insulin-UF： ρ= 0.53; P = 0.03; TroponinT-diuresis： ρ = -0.48, P 〈 0.05; Pro-BNP-diuresis： ρ = -0.39, P 〈 0.01; Troponin T-ProBNP： ρ = 0.77, P 〈 0.0001; albumin-Troponin T： ρ = -0.66, P 〈 0.0001; albumin-ProBNP： ρ = -0.44, P 〈 0.05.CONCLUSION： High BMI associated positively with higher diuresis and albuminemia, and negatively with TropT and Pro-BNP. High BMI-associated better survival may be explained by better urinary output, lowering cardiovascular stress.

Impact of body mass index and gender on quality of life in patients with gastroesophageal reflux disease

AIM： To investigate the symptom presentation and quality of life in obese Chinese patients with gastro- esophageal reflux disease （GERD）. MKTHODS： Data from patients diagnosed with GERD according to the Montreal definition, were collected between January 2009 to March 2010. The enrolled patients were assigned to the normal [body mass in- dex （BMI） 〈 25 kg/m2], overweight （25-30 kg/m2）, and obese （BMI 〉 30 kg/m2） groups. General demographic data, endoscopic findings, and quality of life of the three groups of patients were analyzed and compared.and 15 patients were classified in the normal, over- weight, and obese, respectively. There was significantly more erosive esophagitis （73.3% vs 64.3% vs 39.2%, P = 0.002）, hiatal hernia （60% vs 33.9% vs 16.7%, P = 0.001）, and males （73.3% vs 73.2% vs 32.4%, P = 0.001） in the obese cases. The severity and frequency of heartburn, not acid regurgitation, was positively cor- related with BMI, with a significant association in men, but not in women. Obese patients were prone to have low quality of life scores, with obese women having the lowest scores for mental health. CONCLUSION： In patients with GERD, obese men had the most severe endoscopic and clinical presenta- tion. Obese women had the poorest mental health.

Impact of body mass index on the development of pocket hematoma：A retrospective study in Chinese people

BackgroundPocket hematoma is one of the major complications associated with cardiovascular implantable electronic devices （CIEDs） implantation. The aim of this study is to evaluate the impact of body mass index （BMI） on the occurrence of pocket hematoma after CIEDs implantation.MethodsThe study is a retrospective review of 972 patients receiving CIEDs implantation between 2008 and 2012 in a tertiary hospital.ResultsTwenty two patients （2.2%） developed severe pocket hematoma requiring re-intervention. The hematoma rate （4.6%,n = 15） of patients with a BMI of 〈 23 kg/m2 was significantly higher compared with that of patients with a BMI of≥23 kg/m2 （1.1%, n = 7,P〈 0.001）. In multivariate regression analysis, a BMI 〈 23.0 kg/m2 may be associated with the development of severe pocket hema-toma. An increase of 1.0 kg/m2 in BMI was associated with lower incidence of hematoma formation （OR： 0.84; 95% CI： 0.74-0.95;P = 0.006）.ConclusionBMI 〈 23 kg/m2 was associated with a higher incidence of pocket hematoma, requiring re-intervention. The data sup-port that great care must be taken when patients were with a lower BMI received CIEDs implantation.

Association between body mass index and erosive esophagitis:A meta-analysis

AIM:To conduct a meta-analysis to estimate the determinants of the association between erosive esophagitis (EE)and body mass index(BMI). METHODS:We identified the studies using PubMed. Studies were selected for analysis based on certain inclusion and exclusion criteria.Data were extracted from each study on the basis of predefined items.Metaanalyses were performed to verify the risk factors,such as obesity and gender. RESULTS:Twenty-one studies were included in this systematic review.These studies demonstrated an association between increasing BMI and the presence of EE[95%confidence interval(CI):1.35-1.88,overweight,odds ratio(OR)=1.60,P value homogeneity =0.003,95%CI:1.65-2.55,obese,OR=2.05,P< 0.01].The heterogeneity disappeared by stratifying for gender.No publication bias was observed in this metaanalysis by the Egger method. CONCLUSION:This analysis demonstrates a positive association between BMI and the presence of EE,especially in males.The risk seems to progressively increase with increasing weight.

The Effect of Age and Markers of Obesity on Bone Density in Iraqi Postmenopausal Women

Osteoporosis is a disease characterized by a low bone mineral density and structural deterioration of bone tissue. Leptin is considered to play a role in the maintenance of energy balance and body weight. Weight and body mass index are associated with low bone mineral density with high serum leptin concentration in older women. The study is designed to elucidate the impact of age and BMI （Body Mass Index） on osteoporotic patients （Iraqi postmenopausal women） and the functional role of leptin in those patients. A total of 72 patients divided into three groups according to BMI and two groups according to age： BMD （bone mineral density）, T-score and serum leptin concentration increased as BMI increased, while with increased age, BMD and T-score deceased and serum leptin concentration increased. There is a significant difference of BMD and T-score in BMI （25-30） group and BMI （〉 30） group from that in BMI （〈 25） group. In conclusions： Both age and BMI have an impact on osteoporosis although age shows more impact on the severity of the disease than does BMI. Studying the direct impact of leptin on BMD may open the way in using new methods in treating and preventing the osteoporosis in patients with risk factors.

Clinical Study on Simple Obesity Treated with Abdomen Acupuncture

Objective： To observe the clinical effects of simple obesity treated with abdomen acupuncture. Methods： Sixty patients with simple obesity were allocated to abdomen acupuncture group and body acupuncture group based on the randomized and controlled principle, 30 patients in each group. Fifteen treatments made up one course. The cases were treated for 2 courses. The clinical effects were evaluated by body mass index （BMI） and the declining of body height. Result： The change of BMI and clinical effects were of no significant difference between two groups after 1 course, but there were significant differences after two courses. Conclusion： The clinical effect of abdomen acupuncture treating simple obesity is better, and the effect is persistent and stable.

Effect of low-frequency electroacupuncture on pancreatic endocrine system in patients with simple obesity

Objective： To observe different efficacies of low-frequency electroacupuncture（EA） on pancreatic endocrine system in male and female patients with simple obesity due to spleen deficiency-related dampness. Methods： A total of 80 simple obesity patients were assigned to a male group（n=37） and a female group（n=43）. Both groups received a 30-minute low-frequency EA at Yinlingquan（SP 9）, Sanyinjiao（SP 6）, Zusanli（ST 36）, Fenglong（ST 40）, Quchi（LI 11）, Tianshu（ST 25）, Zhongwan（CV 12）, Shuifen（CV 9）, Qihai（CV 6） and Guanyuan（CV 4）. The treatment was done once a day, and 10 times made up a course of treatment. Patients in both groups were treated for 2 courses. Then the changes in body mass index（BMI）, serum insulin, insulin antibodies and leptin level in the two groups were observed and analyzed. Results： After treatment, the BMI, serum insulin, insulin antibodies and leptin levels were significantly reduced in both groups（P〈0.01 or P〈0.05）; the BMI and serum insulin concentration were more significantly reduced in the male group than those in the female group（both P〈0.01）; and the leptin level was more significantly reduced in the female group than that in the male group（P〈0.01）. Conclusion： EA can significantly regulate BMI and pancreatic endocrine system in both men and women with simple obesity; however, there is a gender difference： better effect for men in reducing BMI and serum insulin and better effect for women in reducing serum leptin level.

Effect of tuina exercise on simple obesity in college students

Objective:To observe the effect of tuina exercise on simple obesity in college students.Methods:Fifty-seven college students with simple obesity were divided into two groups according to the stratified randomization method.Twenty-eight in the tuina exercise group were trained in tuina exercise;while 29 in the auricular acupoint sticking group were treated with acuricular acupoint sticking.The tuina exercise group was trained once every other day,and 10 times made one course.The auricular acupoint sticking was replaced once every 4 d,and 5 times made one course.After 2-course treatment,the total therapeutic effect,weight,body mass index (BMI),waist and hip circumferences,serum total cholesterol (TC),triglyceride (TG),high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were assessed.Results:The total therapeutic effect was 86.2% in the auricular acupoint sticking group and 85.7% in the tuina exercise group.There was no significant difference between the two groups (P>0.05).After treatment,the weight,BMI,waist and hip circumferences were decreased and the differences were statistically significant (all P<0.05).The waist and hip circumferences in the tuina exercise group were lower than those in the auricular acupoint sticking group,showing statistically significant differences (all P<0.05).After treatment,there were no significant intra-group differences in TC,TG,HDL-C and LDL-C in the two groups (all P>0.05),and the between-group differences were not significant (all P>0.05).Conclusion:Tuina exercise has reliable effect in treating obesity.It can produce more significant improvements in waist and hip circumferences than auricular acupoint sticking.But no obvious effect is shown in blood lipid indicators.

The association between weight stability and parenteral nutrition characteristics and survival in patients with colorectal cancer

Objective:Knowledge about the impact of metabolic disturbances and parenteral nutrition(PN)characteristics on the survival of cancer patients receiving PN is limited.We aimed to assess the association between clinical and PN characteristics and survival in colorectal-cancer patients receiving PN support.Methods:Our study included 572 consecutive colorectal-cancer patients who had received PN support between 2008 and 2013.Patient characteristics,body mass index,weight,medical/surgical history,indication for PN,PN data and survival were recorded.Associations between clinical and PN characteristics and survival were analysed with important confounding factors.Results:The final cohort included 437 evaluable patients,with a mean age of 57 years.Eighty-one percent of the study population had advanced stage of colorectal cancer.Unstable weight(weight change≥2.5%)prior to PN initiation[hazard ratio(HR)=1.41,P=0.023]was adversely associated with survival after adjusting for multiple factors including cancer stage.Bowel obstruction(HR=1.75,P=0.017)as a PN indication was associated with worse survival when compared with without bowel obstruction.Higher PN amino acid by ideal body weight(g•kg^(-1))(HR=0.59,P=0.029)was associated with longer survival,whereas a higher percentage of non-PN intravenous calories(HR=1.04,P=0.011)was associated with shorter survival independently of confounding factors.Conclusions:Body mass index and weight stability can be useful nutritional indices for survival prediction in cancer patients receiving PN.PN planning should take into account of non-PN calories to achieve optimal energy support and balance.Future research is needed to define optimal PN amino-acid requirement and energy balance.

Effects of pre-pregnancy body mass index and gestational weight gain on neonatal birth weight

To evaluate the effects of maternal pre-pregnancy body mass index （pre-BMI） and gestational weight gain （GWG） on neonatal birth weight （NBW） in the population of Chinese healthy pregnant women, attempting to guide weight control in pregnancy. A retrospective cohort study of 3772 Chinese women was conducted. The population was stratified by maternal pre-BMI categories as underweight （〈18.5 kg/m2）, normal weight （18.5-23.9 kg/m2）, overweight （24.0-27.9 kg/m2）, and obesity （〉28.0 kg/m2）. The NBW differences were tested among the four groups, and then deeper associations among maternal pre-BMI, GWG, and NBW were investigated by multivariate analysis. NBW increased significantly with the increase of maternal pre-BMI level （P〈0.05）, except overweight to obesity （P〉0.05）. The multivariate analysis showed that both pre-BMI and GWG were positively correlated with NBW （P〈0.05）. Compared with normal pre-BMI, underweight predicted an increased odds ratio of small-for-gestational-age （SGA） and decreased odds ratio for macrosomia and large-for-gestational-age （LGA）, and the results were opposite for overweight. With the increase of GWG, the risk of SGA decreased and the risks of macrosomia and LGA increased. In addition, in different pre-BMI categories, the effects of weight gain in the first trimester on NBW were different （P〈0.05）. NBW is positively affected by both maternal pre-BMI and GWG, extreme pre-BMI and GWG are both associated with increased risks of abnormal birth weight, and maternal pre-BMI may modify the effect of weight gain in each trimester on NBW. A valid GWG guideline for Chinese women is an urgent requirement, whereas existing recommendations seem to be not very suitable for the Chinese.

Effect of acupuncture on serum PYY and nesfatin-1 in obese patients with insulin resistance

Objective To observe the effect of acupuncture on serum peptide YY(PYY)and nesfatin-1 in obese patients with insulin resistance.Methods Ninety-eight obese patients with insulin resistance were divided into a control group and an observation group by the random number table method,with 49 cases in each group.The control group received exercise and dietary interventions,and the observation group received additional acupuncture treatment to the exercise and dietary interventions.The body mass index(BMI),body fat percentage,fasting insulin(FINS),fasting plasma glucose(FPG),homeostasis model assessment for insulin resistance(HOMA-IR),triglyceride(TG),total cholesterol(TC),and serum PYY and nesfatin-1 levels were compared before and after treatment.The efficacy was evaluated after treatment.Results The total effective rate was significantly higher in the observation group than in the control group(P<0.05).After treatment,the BMI,body fat percentage,and serum TG and TC levels decreased significantly in both groups(P<0.05),and were significantly lower in the observation group than those in the control group(P<0.05).The FINS,FPG,HOMA-IR,and serum PYY and nesfatin-1 levels of the control group were not significantly changed after treatment(P>0.05).The FINS,FPG and HOMA-IR of the observation group decreased significantly after treatment(P<0.05),and were lower than those in the control group(P<0.05).The serum PYY and nesfatin-1 levels of the observation group increased significantly after treatment(P<0.05),and were higher than those in the control group(P<0.05).Conclusion Based on exercise and dietary interventions,acupuncture is effective for obese patients with insulin resistance.It can reduce the BMI,body fat percentage,blood lipids,blood glucose,and serum insulin levels and improve insulin resistance.The action may be associated with the up-regulation of serum PYY and nesfatin-1.
