    Full Text Available Thyroid function and microalbuminuria are both associated with vascular disease and endothelial damage. However, whether thyroid function is associated with microalbuminuria is not well established. The objective was to explore the relationship between thyroid hormones and microalbuminuria in Chinese population. A community-based cross-sectional study was performed among 3,346 Chinese adults (aged ≥ 40 years. Serum free triiodothyronine (FT3, free thyroxine (FT4, and TSH (thyroid stimulating hormone were determined by chemiluminescent microparticle immunoassay. A single-void first morning urine sample was obtained for urinary albumin-creatinine ratio measurement. The prevalence of microalbuminuria decreased according to FT3 quartiles (13.2, 9.5, 8.6, and 8.2%, P for trend = 0.0005. A fully adjusted logistic regression analysis showed that high FT3 levels were associated with low prevalent microalbuminuria. The adjusted odds ratios for microalbuminuria were 0.61 (95% CI, 0.43–0.87, P = 0.007 when comparing the highest with the lowest quartile of FT3. The exclusion of participants with abnormal FT3 did not appreciably change the results (OR = 0.69, 95% CI, 0.49–0.98, P = 0.02. We concluded that serum FT3 levels, even within the normal range, were inversely associated with microalbuminuria in middle-aged and elderly Chinese adults. FT3 concentrations might play a role in the pathogenesis of microalbuminuria.

    Hypertension as well as type 2 diabetes mellitus is a major factor in population mortality. Both diseases damage the endothelium, the early sign of which is microalbuminuria, which can be screened by dipstick and can be diagnosed by using immuno-based and high performance liquid chromatography methods. Using high performance liquid chromatography, the non-immunoreactive albumin can be detected as well. The authors aimed at the examination of albuminuria in the case of immunonephelometrically negative patients with high performance liquid chromatography, in diabetic and hypertensive and non-diabetic hypertensive populations. The authors also wanted to compare the present (albumin-creatinine ratio: male: > or =2.5 mg/mmol, female: > or =3.5 mg/mmol) and a new criteria of the Heart Outcomes Prevention Evaluation study (patients without diabetes: immunological method, > or =0.7 mg/mmol; high performance liquid chromatography, > or =3.1 mg/mmol; individuals with diabetes: immunological method, > or =1.4 mg/mmol; high performance liquid chromatography, > or =5.2 mg/mmol) of microalbuminuria. Examination of fresh urines of 469 microalbuminuria negative patients by dipstick were performed by immunonephelometry. Patients, who were microalbuminuria negative by immunonephelometry as well, were further analyzed by high performance liquid chromatography using the Accumintrade mark Kit, based on size-exclusion chromatography. Three times higher albuminuria were found with high performance liquid chromatography than with immunonephelometry. The intraindividual coefficient of variation did not differ in the two methods (37 +/- 31% vs. 40 +/- 31%, p = 0.869; immunonephelometry vs. high performance liquid chromatography; mean +/- standard deviation). Using the present criteria for microalbuminuria, 43% of immunonephelometrically negative patients proved to be microalbuminuric by high performance liquid chromatography.

    Full Text Available PurposeAlthough microalbuminuria is considered as an early marker of nephropathy in diabetic adults, available information in diabetic adolescents is limited. The aim of this study was to investigate prevalence and frequency of regression of microalbuminuria in type 1 (T1DM and type 2 diabetes mellitus (T2DM patients with childhood onset.MethodsOne hundred and nine adolescents (median, 18.9 years; interquartile range (IQR, 16.5-21.0 years with T1DM and 18 T2DM adolescents (median, 17.9 years; IQR, 16.8-18.4 years with repeated measurements of microalbuminuria (first morning urine microalbumin/creatinine ratios were included. The median duration of diabetes was 10.1 (7.8-14.0 years and 5.0 (3.5-5.6 years, respectively, and follow-up period ranged 0.5-7.0 years. Growth parameters, estimated glomerular filtration rate, glycosylated hemoglobin (HbA1c and lipid profiles were obtained after reviewing medical record in each subject.ResultsThe prevalence of microalbuminuria at baseline and evaluation were 21.1% and 17.4% in T1DM, and 44.4% and 38.9% in T2DM. Regression of microalbuminuria was observed in 13 T1DM patients (56.5% and 3 T2DM patients (37.5%, and progression rate was 10.5% and 20% in T1DM and T2DM respectively. In regression T1DM group, HbA1c at baseline and follow-up was lower, and C-peptide at baseline was higher compared to persistent or progression groups. In T2DM, higher triglyceride was observed in persistent group.ConclusionConsiderable regression of microalbuminuria more than progression in diabetes adolescents indicates elevated urinary microalbumin excretion in a single test does not imply irreversible diabetic nephropathy. Careful monitoring and adequate intervention should be emphasized in adolescents with microalbuminuria to prevent rapid progression toward diabetic nephropathy.

    Full Text Available Background. Pentoxifylline is a nonspecific phosphodiesterase inhibitor with anti-inflammatory properties. Human studies have proved its antiproteinuric effect in patients with glomerular diseases, but this study was designed to assess the effects of add-on pentoxifylline to available treatment on reduction of microalbuminuria in diabetic patients without glomerular diseases. Methods. In a double-blind placebo-controlled, randomized study we evaluated the influence of pentoxifylline on microalbuminuria in type 2 diabetic patients. 40 diabetic patients with estimated glomerular filtration rate (eGFR of more than 60 mL/min/1.73 m2 in eight weeks and microalbuminuria were randomized to two groups which will receive pentoxifylline 1200 mg/day or placebo added to regular medications for 6 months. albuminuria; eGFR was evaluated at three- and six-month follow-up period. Results. Baseline characteristics were similar between the two groups. At six months, the mean estimated GFR and albuminuria were not different between two groups at 3- and 6-month follow-up. Trend of albumin to creatinine ratio, systolic and diastolic blood pressure, and eGFR in both groups were decreased, but no significant differences were noted between two groups (P value > 0.05. Conclusion. Pentoxifylline has not a significant additive antimicroalbuminuric effect compared with placebo in patients with type 2 diabetes with early stage of kidney disease; however, further clinical investigations are necessary to be done.

    Microalbuminuria is often regarded as a sign of end-organ damage due to diabetes and/or hypertension, and as such to be associated with an increased risk for cardiovascular events. It has been questioned whether isolated microalbuminuria, that is microalbuminuria in the absence of a cardiovascular disease (CVD) history, hypertension and diabetes has clinical relevance. Included were 8356 subjects who participated in the first four screening rounds of the PREVEND study, a prospective, community-based, observational cohort study. Isolated microalbuminuria was defined as microalbuminuria (30-300 mg/24 h), in the absence of a CVD history, hypertension (blood pressuredefinition of isolated microalbuminuria, in which 2250 person-years of follow-up were available. In subjects with isolated microalbuminuria, the incidence rates of cardiovascular events and mortality, hypertension and diabetes were 15.3, 28.9 and 8.9 per 1000 person-year follow-up, respectively. Subjects with isolated microalbuminuria had an increased risk for cardiovascular events and mortality [crude HR 2.23 (1.63-3.07); Phypertension [OR 1.95 (1.47-2.59); Phypertension and/or diabetes. This increased risk remained significant after adjustment for age and gender. The relative risk held by isolated microalbuminuria was similar to the relative risk held by microalbuminuria in subjects that did have a CVD history, hypertension and/or diabetes. Isolated microalbuminuria indicates a poor prognosis and warrants medical attention.

    OBJECTIVE: Microalbuminuria associates with increased risk of atherosclerosis in individuals without diabetes. We hypothesized that transendothelial lipoprotein exchange is elevated among such individuals, possibly explaining increased intimal lipoprotein accumulation and thus atherosclerosis....... METHODS: Using an in vivo isotope technique, transendothelial exchange of low density lipoprotein (LDL) was measured in 77 non-diabetic individuals. Autologous 131-iodinated LDL was reinjected intravenously, and the 1-h fractional escape rate was calculated as index of transendothelial exchange. RESULTS......: There was no difference in transendothelial LDL exchange between subjects with microalbuminuria versus normoalbuminuria (mean (95% confidence interval) 3.8%/h (3.3-4.3%/h) versus 4.2%/h (3.7-4.7%/h); P=0.33). In contrast, there was a positive correlation between transendothelial LDL exchange and (logarithmically...

    Microalbuminuria is a significant risk factor associated with nephropathy, retinopathy, and cardiovascular disease; however, there are no previous reports on the relationship of microalbuminuria with diabetic foot ulcers or stroke, despite the fact that microalbuminuria is a marker of vascular damage. The purpose of this study was to determine the relationship of microalbuminuria with diabetic foot ulcers in type II diabetes patients. In this, cross-sectional clinical study, outpatients of the offices at first level medical care in Durango, Mexico, were included in one of two groups; (a) patients with diabetic foot ulcers and (b) control of group patients without diabetic foot ulcers. Diabetic foot diagnosis was established on the basis of clinical criteria and pletismography. Patients diagnosed with renal disease, urinary tract infection, acute febrile illness, or heart failure and those receiving angiotensin-converting enzyme inhibitors were excluded from the study. Microalbuminuria was measured, on a 24-h urine collection, by precipitation with sulfasalicylic acid, and turbidity was determined by measuring absorbance with a spectrophotometer. The study included 670 diabetic patients. Using both odds ratio and logistic regression analyses, diabetes duration, cigarette smoking, aging, and microalbuminuria showed a strong relationship with diabetic foot ulcers. Microalbuminuria should be considered as an independent risk factor for diabetic foot ulcers.

    Smoking cessation in newly diagnosed type 2 diabetes patients is reported to be associated with amelioration of metabolic parameters and blood pressure (BP), and the reduction of microalbuminuria. The aim of this study is to demonstrate changes in BP, pulse rate (PR), and microalbuminuria in already diagnosed diabetes patients who quit smoking. We retrospectively evaluated diabetes outpatients who were habitual smokers, and who visited to our smoking cessation clinic. Patients were divided into two groups based on their smoking status at the termination of a 3-month smoking cessation program (smoking cessation group and smoking group), and analyzed systolic and diastolic BPs, PR, HbA1c, and body weight at the start date, and at 1, 3, 6, and 12 months thereafter. The urinary albumin-to-creatinine ratio was also measured at the start date and at 12 months. Thirty-five patients met our criteria. Mean diabetes duration was 12 years. Eighteen patients (52%) quit smoking. Success or failure of smoking cessation depended on nicotine dependence rather than good or bad glycemic control. Both BP and PR decreased significantly after 1 month or later in the smoking cessation group without worsening HbA1c, while both parameters did not show any changes in the smoking group. Microalbuminuria was also ameliorated significantly at 12 months compared with that at the start date in the smoking cessation group (95.8 ± 92.9 mg/gCr vs. 75.5 ± 96.3 mg/gCr, P = 0.0059), while it did not show a significant change in the smoking group. (61.9 ± 43.5 mg/gCr vs. 97.7 ± 90.4 mg/gCr, P = 0.1039). Smoking cessation might cause a reduction in chronic kidney disease progression through ameliorating microalbuminuria without metabolic adverse effects in patients already diagnosed with diabetes mellitus.

    Increased glycemic exposure, even below the diagnostic criteria for diabetes mellitus, is crucial in the pathogenesis of diabetic microvascular complications represented by microalbuminuria. Nonetheless, there is limited evidence regarding which single nucleotide polymorphisms (SNPs) are associated with prediabetes and whether genetic predisposition to prediabetes is related to microalbuminuria, especially in the general population. Our objective was to answer these questions. We conducted a genomewide association study (GWAS) separately on two population-based cohorts, Ansung and Ansan, in the Korean Genome and Epidemiology Study (KoGES). The initial GWAS was carried out on the Ansung cohort, followed by a replication study on the Ansan cohort. A total of 5682 native Korean participants without a significant medical illness were classified into either control group (n = 3153) or prediabetic group (n = 2529). In the GWAS, we identified two susceptibility loci associated with prediabetes, one at 17p15.3-p15.1 in the GCK gene and another at 7p15.1 in YKT6. When variations in GCK and YKT6 were used as a model of prediabetes, this genetically determined prediabetes increased microalbuminuria. Multiple logistic regression analyses revealed that fasting glucose concentration in plasma and SNP rs2908289 in GCK were associated with microalbuminuria, and adjustment for age, gender, smoking history, systolic blood pressure, waist circumference, and serum triglyceride levels did not attenuate this association. Our results suggest that prediabetes and the associated SNPs may predispose to microalbuminuria before the diagnosis of diabetes mellitus. Further studies are needed to explore the details of the physiological and molecular mechanisms underlying this genetic association.

    A growing body of evidence suggest that obese individuals are under risk of renal parenchymal disorders when compared to nonobese counterparts. Microalbuminuria is the early marker of renal involvement. Although most of obese patients carries multiple risk factors for microalbuminuria, some obese individuals without risk factor may progress to microalbuminuria. The present study was performed to examine the role of ICAM-1 gene 1462A>G (K469E) polymorphism on microalbuminuria in obese subjects without diabetes mellitus, hypertension, hiperlipidemia and older age. Ninety eight obese and 96 nonobese individuals without a comorbidity enrolled into the study. Serum ICAM-1 level was measured by enzyme linked immunoabsorbent assay (ELISA) method. ICAM-1 gene 1462A>G (K469E) polymorphism was examined by restriction fragment length polymorphism-polymerase chain reaction (RFLP-PCR). Nepholometric method was used to examine urinary albumin loss, and microalbuminuria was measured by albumin to creatinine ratio. Obese individuals had significantly higher microalbuminuria and proteinuria level compared to nonobese subjects (p: 0.043 and p: 0.011; respectively). GG genotype of ICAM-1 carriers have significantly higher microalbuminuria compared to individuals with AA or AG genotype carriers (p: 0.042). Serum ICAM-1 level was significantly correlated with creatinine and microalbuminuria (p: 0.002 and p: 0.03; respectively). Logistic regression analysis indicated a 7.39 fold increased risk of microalbuminuria in individuals with GG genotype of ICAM-1 gene 1462A>G (K469E) polymorphism. GG genotype of ICAM-1 gene K469E polymorphism is associated with increased microalbuminuria in obese individuals without another metabolic risk factor.

    Hemolytic uremic syndrome (HUS) is characterized by the presence of microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney failure. It is the leading cause of acute kidney failure in children under 3 years of age. A variable number of patients develop proteinuria, hypertension, and chronic renal failure. To evaluate the renal involvement in pediatric patients diagnosed with HUS using the microalbumin/creatinine ratio. Descriptive concurrent cohort study that analyzed the presence of microalbuminuria in patients diagnosed with HUS between January 2001 and March 2012, who evolved without hypertension and normal renal function (clearance greater than 90ml/min using Schwartz formula). Demographic factors (age, sex), clinical presentation at time of diagnosis, use of antibiotics prior to admission, and need for renal replacement therapy were evaluated. Of the 24 patients studied, 54% were male. The mean age at diagnosis was two years. Peritoneal dialysis was required in 45%, and 33% developed persistent microalbuminuria. Antiproteinuric treatment was introduce in 4 patients, with good response. The mean follow-up was 6 years (range 6 months to 11 years). The serum creatinine returned to normal in all patients during follow up. The percentage of persistent microalbuminuria found in patients with a previous diagnosis of HUS was similar in our group to that described in the literature. Antiproteinuric treatment could delay kidney damage, but further multicenter prospective studies are necessary. Copyright © 2015. Publicado por Elsevier España, S.L.U.

    Objective: To measure and correlate the levels of thiamine and dyslipidaemia in microalbuminuric diabetics. Methods: Cross-sectional comparative study was conducted at the Department of Biochemistry and Molecular Biology, Army Medical College, Rawalpindi, from January 2009 to December 2010, and comprised 60 known diabetic patients, who were inducted from diabetic clinics of Rawalpindi. These patients were divided into three equal groups, with group I (n=20) being normal healthy individuals, group II comprised of microalbuminurics type 2 diabetics (n=20) and group III (n=20) were macroalbuminuric type 2 diabetics, based on their albumin excretion rate. The healthy volunteers (n=20) had blood glucose less than 6 mmol/L and were inducted as the comparison group. Fasting blood samples of diabetic and control groups were analysed for glucose, glycosylated haemoglobin, lipid profile, thiamine chloride and thiamine monophosphate. Besides, 24-hour urine samples were analysed for microalbuminuria, thiamine chloride and thiamine monophosphate. Results: Plasma thiamine chloride and thiamine monophosphate levels were found to be significantly (p<0.001) reduced in the diabetics (n=60) compared to the controls (n=20). Furthermore, there was a progressive decline in these levels with increasing albuminuria; the lowest being in the macroalbuminuric group (group IV). Urinary thiamine levels were significantly (p<0.001) higher in the diabetics compared to the controls. These changes were more pronounced as albuminuria level increased; the highest being in group IV. The parameters of lipid profile, including triglycerides, total cholesterol and low-density lipoprotein cholesterol, were significantly (p<0.001) higher in diabetics and showed progressive increase with worsening albuminuria. Whereas, the high-density lipoprotein cholesterol levels were significantly (p<0.001) reduced in diabetics and showed progressive decline as the microalbuminuria status worsened. Furthermore, a

    Full Text Available INTRODUCTION. The prevalence of hypertension is two times higher in diabetics than in non-diabetics. In type 1 diabetes mellitus (T1DM, the incidence of hypertension is similar to the incidence of nephropathy. In obese patients with type 2 DM (T2DM there can be associated complications of hyperinsulinaemia, dyslipidaemia, and hypertension, which can lead to coronary artery disease and stroke. These associated complications are the result of a genetic defect that produces insulin resistance - Syndrome X. Increased microalbuminuria correlates with increased levels of blood pressure (BP and increased LDL cholesterol, and this is why microalbuminuria is associated with an increase in cardiovascular deaths in diabetics, even in the absence of renal failure. AIM. The aim of this study was to research the influence of a patient's age, diabetes duration, and obesity on the frequency of hypertension and its association with microalbuminuria inT1DM and T2DM. METHOD. 168 hospitalized patients with DM (79T1DM, 89T2DM were analyzed. The main outcome measures were: 24-hour urinary albumin excretion rate by radioimmunoassay (MA=30-30O mg/24h, arterial hypertension (systolic BP>140 mm Hg and/or diastolic BP>90 mm Hg, and body mass index (BMI. RESULTS. Microalbuminuria was detected in 42% of patients with T1DM and 47% of patients with T2DM. 34% of T1DM patients and 78% of T2DM patients were hypertensive. Patients were divided into four groups, according to the presence of hypertension and microalbuminuria; Group I - patients with hypertension and MA, Group II - patients with hypertension but without MA, Group III - patients without hypertension and MA, Group IV - patients without hypertension but with MA. 44% of T1DM patients were without hypertension and microalbuminuria, while the most frequent T2DM patients were those with hypertension (37% with and 41% without microalbuminuria. A significant correlation between BMI and diastolic BP in both types of DM (p<0

    Urinary albumin excretion in a representative sample of 679 patients with Type I (insulin-dependent) diabetes, 18 to 50 years of age, was investigated. Patients on antihypertensive therapy were excluded. Urinary albumin excretion was examined in one 24 hour urine sample using an ELISA technique....... Twenty-three per cent of the patients had microalbuminuria, i.e., 30-300 mg albumin/24 h. The prevalence of microalbuminuria was independent of sex, age, insulin dose and diabetes duration. In the majority of those cases in which microalbuminuria was found during the first 10 years of diabetes......, the concentrations were in the lower range, i.e., 30-50 mg/24 h. The prevalence of incipient nephropathy (urinary albumin excretion in a single urine sample of 51-300 mg/24 h) increased with diabetes duration. In patients with incipient nephropathy hemoglobin A1c tended to be, and blood pressure was, elevated...

    Diabetes is one of the most common endocrine disorders characterized by hyperglycaemia. Diabetic nephropathy is a consequence of long standing diabetes. The prevalence of microalbuminuria predicts progression to diabetic nephropathy. The present study was conducted to determine the prevalence of microalbuminuria in relation to duration of diabetes, BMI, Serum Creatinine and HbA1c in an ethnic group of Type 2 diabetes mellitus residing in Karachi. Methods: This cross-sectional descriptive study was carried out in a community diabetic centre, located at Garden East Karachi from July to December 2007. One hundred known Type 2 diabetic patients with age 30 - 70 years were included in the study. Informed consent and a structured questionnaire of each patient were recorded. Fasting venous blood and morning urine sample was collected for analysis of creatinine, HbA1c and microalbuminuria respectively. Statistical analysis was done using SPSS version 13.0. Pearson correlation was applied to observe association of microalbuminuria with different parameters. All p-values 7%) or heredity factors. Screening for microalbuminuria and HbA1c test should be done in both newly and already diagnosed Type 2 diabetic patients as an early marker of renal dysfunction and glycemic control. (author)

    The prevalent raise of type 2 diabetes (T2D) around the globe, are creating higher risk for cardiovascular diseases (CVDs) and increasing strain on each country's health care budget in the world. Microalbuminuria has appeared as a key parameter in diabetic patients. Microalbuminuria is also related to increased cardiovascular morbidity in people who are non-obese diabetic. Some studies have suggested that consumption of symbiotic foods might help improve the metabolic profile, inflammatory factors and biomarkers of oxidative stress. The aim of trial was to determine the effect of symbiotic supplementation on glycemic control, lipid profiles and microalbuminuria in non-obese T2D. In this randomized, double-blind, clinically controlled trial, 70 patients with T2D (28 females, 42 males) were randomly divided into two groups ( n  = 35 for each group). The symbiotic group (SG) consumed 500 mg/d of symbiotic supplementations containing probiotics (Lactobacillus family, Bifidobacterium family, Streptococus thermophilus), Prebiotics (Fructo oligosaccharide) and B group vitamins (1 mg), lactose (0.5 mg), malt-dextrin, magnesium saturate and the placebo group (PG) consumed capsules filled with row starch and also B group vitamins (1 mg), lactose (0.5 mg), malt-dextrin, magnesium saturate for 9 weeks. Fasting blood glucose (FBG), hemoglobin A1c (HbA1c), blood lipid profiles, 24-h dietary recalls, and anthropometric measurements were measured at the baseline and at the end of trial. SPSS software, version 16 was used to test the data and the results were expressed as mean ± standard deviation. Paired samples T-Test were used to compare continuous variables within groups. Comparison between different groups was performed through two independent samples T-Test. In the absence of normal distribution, the comparison between the groups was made using non-parametric Wilcoxon on signed ranks and Mann-Whitney tests. P values Symbiotic supplementation decreased

    Full Text Available OBJECTIVE: To assess the association between microalbuminuria with ambulatory blood pressure monitoring in normotensive individuals with insulin-dependent diabetes mellitus. METHODS: Thirty-seven patients underwent determination of the rate of urinary excretion of albumin through radioimmunoassay and ambulatory blood pressure monitoring. Their mean age was 26.5±6.7 years, and the mean duration of their disease was 8 (1-34 years. Microalbuminuria was defined as urinary excretion of albumin > or = 20 and 50% and diastolic pressure load > 30% during sleep was associated with microalbuminuria (p=0.008. The pressure drop during sleep did not differ between the groups. CONCLUSION: Microalbuminuric normotensive insulin-dependent diabetic patients show greater mean pressure value and pressure load during ambulatory blood pressure monitoring, and these variables correlate with urinary excretion of albumin.

    and hypertension, diabetes mellitus, dyslipidemia, smoking and obesity. METHODS: The presence of microalbuminuria in a group of hypertensive patients (73 individuals and in a group of patients with coronary artery disease (39 individuals was determined and compared with a control group (43 individuals. Microalbuminuria was defined as an albumin/creatinine ratio higher than 30 and lower than 300 in a spot morning urine sample. The chi-square test and the Fisher’s exact test were used in the statistical analysis. RESULTS: Microalbuminuria was present in 9.5% of the hypertensive individuals and in 33% of the patients with coronary artery disease, and was absent in individuals of the control group. When the occurrence of microalbuminuria was analyzed according to the different clinical parameters, regardless of the group involved, a statistically significant correlation was found with age, diabetes and dyslipidemia. CONCLUSION: 1 The prevalence of microalbuminuria in hypertensive individuals is high, and is even higher in patients with coronary artery disease; 2 There is a correlation of the presence of microalbuminuria with age, diabetes and dyslipidemia.

    Full Text Available Microalbuminuria is a known early predictive factor for renal and cardiovascular diseases, not only for patients with diabetes mellitus or hypertension but also in the general population. However, the prevalence and risk factors associated with microalbuminuria in Korean youth are unknown.The aims of this study are to evaluate the prevalence of microalbuminuria and the association between microalbuminuria and obesity or cardiometabolic risk factors in Korean children and adolescents without diabetes.This study examines data obtained from the Korea National Health and Nutrition Examination Survey (between 2011 and 2014. It includes a total of 1,976 participants aged between 10 and 19 years (boys 1,128 and girls 848. Microalbuminuria was defined as a urine albumin-to-creatinine ratio (UACR of ≥ 30 mg/g and < 300 mg/g. Association between microalbuminuria and the risk factors for cardiometabolic diseases including insulin resistance was evaluated.The prevalence of microalbuminuria was found to be 3.0% in Korean children and adolescents over this time period. The mean UACR for non-obese youth was significantly greater than that found in obese youth (3.2 ± 0.1 mg/g in the non-obese group vs. 2.1 ± 0.2 mg/g in the obese group; P < 0.001. In multiple logistic regression analysis, microalbuminuria was associated with hyperglycemia (OR 2.62, 95% CI 1.09-6.30 and hemoglobin A1c (OR 3.34, 95% CI 1.09-10.17 in the non-obese group and hypertension (OR 14.10, 95% CI 1.12-177.98 and HbA1c (OR 6.68, 95% CI 1.87-23.95 in the obese group.The prevalence of microalbuminuria is not prominent in obese children and adolescents. Our findings demonstrated that the presence of hypertension and hyperglycemia was associated with microalbuminuria. Especially Hemoglobin A1c was associated with microalbuminuria in youths regardless of weight status. Microalbuminuria in pediatric population can be a helpful marker for the risk of cardiovascular disease.

    Full Text Available The aim of the study was to investigate the association between elevated serum fetuin-A and increased urine albumin excretion in obese rats, and whether increased urine albumin excretion was modified by improving hepatic steatosis and lipid metabolism disorder. Male Wistar rats 4 weeks in age were randomly divided into three groups and fed with normal chow (control group, high-fat chow (obesity group, or high-fat chow plus fenofibrate (fenofibrate group. After 24 weeks, both body weight and visceral fat/body weight ratio in obese rats were higher than in controls. A difference in serology markers and pathology associated with hepatic steatosis was also found among the three groups. Serum fetuin-A and the expression of NF-κB in the liver were increased, while serum adiponectin was decreased in obese rats in comparison to controls (. Urinary albumin/creatinine ratio (ACR was increased in the obesity group compared to controls (. The fenofibrate intervention reduced serum fetuin-A and NF-κB expression in the liver and increased serum adiponectin compared to obese rats and was accompanied by decrease in ACR. A positive correlation was found between ACR and fetuin-A (, , and a negative correlation was found between ACR and adiponectin (, . We conclude that elevated fetuin-A levels are associated with microalbuminuria in obese rats, and abnormal albuminuria is reversible by improving hepatic steatosis.

    The aim of the study was to assess the association of serum uric acid levels with microalbuminuria -urinary albumin excretion (UAE)> or = 30mg/24h-. Cross-sectional study in 429 (220 women) hypertensive, non diabetic, never treated patients (mean age: 47 years) with glomerular filtration rate > or =60ml/min/1.73m(2). The prevalence of microalbuminuria was 20.5%; 18% had hyperuricemia and 47% fulfilled the criteria for metabolic syndrome (MS). Baseline UAE correlated in the unvaried analysis to diastolic blood pressure, waist circumference, high-density lipoprotein cholesterol and uric acid. In multiple linear regression models, only MS (beta=0.113; p=0.03), and serum uric acid values (beta=0.04; p=0.05) were independently associated with logUAE, after adjustment for age and sex. Hyperuricemia (serum uric acid level > or =7.0mg/dl for men and > or =6.5mg/dl for women; odds ratio=2.18; 95% confidence interval, 1.21-3.92; p=0.010), and MS (odds ratio=2.16; 95% confidence interval, 1.32-3.53; p=0.002) were independently associated with a higher risk of microalbuminuria in multiple logistic regression analyses. The prevalence of microalbuminuria was 45.8% in patients with coexistent MS and hyperuricemia, as compared to 13.6% in hypertensive patients without it (p<0.001). In patients with concomitant MS and hyperuricemia the probability of being microalbuminuric was 3.7 times higher than in patients without those factors. Serum uric acid level is associated with microalbuminuria. Coexistence of MS and hyperuricemia in hypertensive patients increases almost 4 times the odds of being microalbuminuric.

    PURPOSE: Microalbuminuria predicts early mortality in non-insulin-dependent-diabetes mellitus patients (NIDDM). Our objective in the present study was to compare and assess the relationship between 24-hour, day and nocturnal ambulatory blood pressure (BP) and urinary albumin excretion rate (UAE) in microalbuminuric and normoalbuminuric NIDDM and in normal control subjects. PATIENTS AND METHODS: In the present cross-sectional study, 24 hour ambulatory BP (daytime BP and nocturnal BP) and HbA1c were compared in microalbuminuric (n = 10) and nonmicroalbuminuric NIDDM patients (n = 10) and in nondiabetic controls (n = 9). None of the patients were taking antihypertensive agents. RESULTS: In the microlbuminuric group, whereas 24 hour and daytime systolic BP differed significantly from control values (P < 0.025 and P < 0.05 respectively), there was no difference between diabetic groups. However, nocturnal systolic BP in the microalbuminuric group was significantly higher than in the normoalbuminuric diabetic patients (139 vs. 125) (P < 0.05) and a significant difference was also found between the NIDDM patients and the control group (139, 125 vs. 114) (P < 0.025). In multiple regression analysis, only nocturnal systolic BP showed a significant relationship with UAE (P < 0.05). CONCLUSIONS: We suggest that the higher nocturnal systolic blood pressure seen in our microalbuminuric NIDDM patients may contribute to the increased morbidity in this group.

    Modifiable lifestyle-related factors are associated with risk of coronary heart disease and may also influence kidney disease risk. Community-based prospective cohort study. 2,354 African American and white participants aged 28-40 years without baseline microalbuminuria or estimated glomerular filtration rate food habits, obesity, and diet quality, which was based on 8 fundamental components of the Dietary Approaches to Stop Hypertension (DASH) diet, including increased intake of fruits, vegetables, low-fat dairy products, whole grains, and nuts and legumes and reduced intake of sodium, sugar-sweetened beverages, and red and processed meats. Spot urine albumin-creatinine ratios were obtained at baseline (1995-1996) and three 5-year follow-up examinations (5, 10, and 15 years' follow-up). Incident microalbuminuria was defined as the presence of age- and sex-adjusted albumin-creatinine ratio ≥25 mg/g at 2 or more of the successive follow-up examinations. During the 15-year follow-up, 77 (3.3%) individuals developed incident microalbuminuria. After multivariable adjustment, poor diet quality (OR, 2.0; 95% CI, 1.1-3.4) and obesity (OR, 1.9; 95% CI, 1.1-3.3) were associated significantly with microalbuminuria; current smoking (OR, 1.6; 95% CI, 0.9-2.8) was associated with microalbuminuria, although the CI crossed 1.0. Neither low physical activity (OR, 1.0; 95% CI, 0.5-1.8) nor fast food consumption (OR, 1.2; 95% CI, 0.7-2.3) was associated with microalbuminuria. Compared with individuals with no unhealthy lifestyle-related factors (poor diet quality, current smoking, and obesity), adjusted odds of incident microalbuminuria were 131%, 273%, and 634% higher for the presence of 1 (OR, 2.3; 95% CI, 1.3-4.3), 2 (OR, 3.7; 95% CI, 1.8-7.7), and 3 (OR, 7.3; 95% CI, 2.1-26.1) unhealthy lifestyle-related factors. Self-reported dietary history and physical activity, low number of outcomes. Consuming an unhealthy diet and obesity are associated with incident microalbuminuria

    Full Text Available Abstract    BACKGROUND: Enhancement of albumin exertion in urine increases the risk of renal and ischemic heart diseases (IHD. We assessed the association of urine albumin and sub-clinical IHD in a random sample of Iranian general population.    METHODS: The random sample in general population in Isfahan County was recruited to the cross-sectional study. From the all sample blood pressure and lipid profile were assessed and morning urine spot was measured for albumin and Creatinine. Microalbuminuria was defined either Albumin-Creatinine Ratio (ACR was 30-300mg. Also, the standard 12 lead electrocardiogram (ECG was carried out for all participants. The ECG pattern was divided to two categories; normal or ECG with ischemia. The logistic regression model was determined the odds of albuminuria for ischemic changes in ECG.    RESULTS: 999 subjects, age 35-70 years, participated to study. From all, 40.8% were male. Microalbuminuria was detected in 8% and sub-clinical ECG ischemic changes were found in 23.4%. The most frequent ischemic change was T wave inversion. The mean urine albumin levels in subjects with normal ECG was 9.6±14.6 mg/ml and in ischemic group was 8.5±12.2 mg/ml and they did not have statistically different. The odds ratios of neither Albumin-Creatinine ratio nor microalbuminuria were in significant range for risk to ischemic changes in ECG of apparently healthy participants.

    Full Text Available Prompt detection of renal involvement through evaluation of microalbuminuria can both reduce mortality in diabetic patients and significantly reduce the cost of managing these patients. To this end, Micral test strips have been used as a screeing tool in this group of patients though not yet in our country. The present study aimed to evaluate this test and to abtain a simpler and less expensive method of screening for microlbuminuria. In this study, 200 type 1 and type 2 diabetic patients referred to the Endocrine & Metabolims Research Center of the Tehran university of medical Sciences were evaluated for microabluminuria. Entry criteria consisted of a history of recognized diabetes longer than or equal to 5 years. Exclusion criteria included development of urinary tract infection, pyrexia, and a history of uncontrolled hypertension. Every patient first completed a data questionnaire and then provided a first-void urine sample, which was tested for microalbuminuria with a urinary protein test strip (an Iranian-made Uri-Yab and a German-made BM-test-GP strip and the sulphasalicylic acid chemical method. Negative samples were tested further using Micral test strips (based on gold-lable immunochromatograpy and the microalbumin measurement kit manufactured by Dako. Germany (based on turbidometry using a Hitachi autoanalyser. 126 women and 74 men were recruited into the study. The average age of the sample was 40.7 years (range=16 to 63 years; 17 patients had IDDM and 173, NIDDM. Average duration of recognized diabetes was 8.75 years. Based on results obtained using chemical analysis and foreign-made tests strips, 46 patients (23% had macroalbuminuria, though the detection rate using Iranian-made test strips was 18 percent (36 patients. A further 16.2 percent of patients had microalbuminuria, with an average urinary albumin excertion of 28.7 mg per liter. Compared with colorimetric methos, the Micral test yieled a sensitivity of 93% and a specificity

    The effect of resolving metabolic syndrome on target organ damage in hypertensive patients is not well described. We evaluated whether treating metabolic syndrome (MetS) with an angiotensin receptor blocker subsequently reduced microalbuminuria in the K-MetS cohort. Among 10,601 total metabolic syndrome patients, 3,250 (52.2% male, 56.2±10.0 years) with sufficient data on five specific metabolic components were included in this study. Patients were divided into four groups based on MetS status at baseline and 3 months. All patients received an angiotensin receptor blocker, fimasartan, for these 3 months; thereafter, treatment was modified at the discretion of each patient's physician. Microalbuminuria and the albumin/creatine ratio were evaluated as a proxy of organ damage. Blood pressure and waist circumference decreased from baseline to 3 months and 1 year. The average albumin/creatinine ratio significantly improved during the first three months of the study from 36.0±147.4 to 21.0±74.9 mg/g (pTreatment of hypertensive patients for one year with the angiotensin receptor blocker fimasartan significantly reduced the albumin/creatine ratio, irrespective of whether the patient had MetS; however, the albumin/creatinine ratio was significantly higher in patents with persistent or newly developed MetS compared to patients without MetS. Additionally, these findings were more prominent in women than in men.

    Full Text Available Diabetic retinopathy is one of the leading causes of blindness in working-age individuals. Diabetic patients with proteinuria or those on dialysis usually present severe forms of diabetic retinopathy, but the association of diabetic retinopathy with early stages of diabetic nephropathy has not been entirely established. A cross-sectional study was conducted on 1214 type 2 diabetic patients to determine whether microalbuminuria is associated with proliferative diabetic retinopathy in these patients. Patients were evaluated by direct and indirect ophthalmoscopy and grouped according to the presence or absence of proliferative diabetic retinopathy. The agreement of diabetic retinopathy classification performed by ophthalmoscopy and by stereoscopic color fundus photographs was 95.1% (kappa = 0.735; P < 0.001. Demographic information, smoking history, anthropometric and blood pressure measurements, glycemic and lipid profile, and urinary albumin were evaluated. On multiple regression analysis, diabetic nephropathy (OR = 5.18, 95% CI = 2.91-9.22, P < 0.001, insulin use (OR = 2.52, 95% CI = 1.47-4.31, P = 0.001 and diabetes duration (OR = 1.04, 95% CI = 1.01-1.07, P = 0.011 were positively associated with proliferative diabetic retinopathy, and body mass index (OR = 0.90, 95% CI = 0.86-0.96, P < 0.001 was negatively associated with it. When patients with macroalbuminuria and on dialysis were excluded, microalbuminuria (OR = 3.3, 95% CI = 1.56-6.98, P = 0.002 remained associated with proliferative diabetic retinopathy. Therefore, type 2 diabetic patients with proliferative diabetic retinopathy more often presented renal involvement, including urinary albumin excretion within the microalbuminuria range. Therefore, all patients with proliferative diabetic retinopathy should undergo an evaluation of renal function including urinary albumin measurements.

    Full Text Available BACKGROUND: Hyperuricemia is now regarded as a risk factor for cardiovascular disease. Micro-albuminuria is associated with increased risk for cardiovascular disease and chronic kidney disease. We hypothesized that elevated serum uric acid (UA is associated with development of micro-albuminuria in the general population. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a community-based prospective cohort study. A total of 1862 subjects from southern Taiwan, all older than 40 years, were screened and 993 of these participants without micro-albuminuria were followed for 4 years. Urinary albumin-to-creatinine ratio was measured two times per year. A multiple linear regression model indicated that serum UA was independently associated with ln(ACR after adjustment for 8 factors (age, sex, and 6 metabolic metrics (β = 0.194, p<0.01. Logistic regression analysis indicated that each 1 mg/dL increase of UA was associated with a 1.42-fold increased risk of micro-albuminuria after adjustment for the same 8 factors (OR = 1.42, 95% CI: 1.27-1.59, p<0.01. A Cox regression model using subjects with serum UA less than 5 mg/dL as reference group indicated higher hazard ratios (HRs only found in subjects with serum UA more than 7 mg/dL (HR = 3.54, 95% CI: 2.11-5.93, p<0.01 and not in subjects with serum UA of 5 to 7 mg/dL (HR = 1.30, 95% CI: 0.82-2.07, p = 0.15. CONCLUSION: Hyperuricemia is significantly associated with micro-albuminuria in middle-aged and elderly males and females from a general population in Taiwan. Elevated serum UA is an independent predictor for development of micro-albuminuria in this population.

    To determine the relationship of insulin resistance with microalbuminuria in patients of type-2 Diabetes mellitus and observe gender difference if any. Study Design: A cross-sectional study. Place and Duration of Study: Diabetes Clinic of Combined Military Hospital, Malir Cantt, from April to August 2007. Methodology: One hundred and fifty five patients of type-2 Diabetes mellitus were included in the study who had either microalbuminuria or normo albuminuria. Body mass index, waist circumference and blood pressure were recorded. Fasting venous blood sample was collected for plasma glucose (FPG), serum insulin, total and HDL cholesterol, triglycerides, creatinine and HbA1c. Urine albumin excretion was determined using urine albumin to creatinine ratio. Insulin resistance was calculated from fasting plasma glucose and serum insulin levels, using homeostatic model assessment of insulin resistance (HOMA-IR). Correlation and association testing was carried out with significance at p < 0.05. Results: Microalbuminuria was found to be significantly correlated with HOMA-IR (r = 0.33, p < 0.001), serum insulin (r = 0.28, p = < 0.001), body mass index (r = 0.18, p = 0.02) and waist circumference (r = 0.21, p = 0.008). This correlation was more significant in women (n = 85, r = 0.48, p = < 0.0001) as compared to men (n = 70, r = 0.14, p = 0.12). The correlation between HOMA-IR and urine albumin excretion remained highly significant (p = 0.001) after controlling for gender, age, duration of diabetes, waist circumference, hypertension, triglycerides and HbA1c. Conclusion: Urinary albumin excretion in patients of type-2 diabetes is strongly associated with insulin resistance and related cardiovascular risk factors. This association appears to be stronger in women than the men, in our population. (author)

    Microalbuminuria is a known complication of diabetes mellitus but it is also a cardiovascular risk factor commonly present among hypertensive (non diabetic) population. The prevalence of microalbuminuria is variable and it has been never estimated in our region. The aim of this study has been to determine the prevalence of microalbuminuria in hypertensive (non diabetic) and diabetic population in Extremadura (Spain). The study included diabetic patients and non-diabetic hypertensive ones randomly selected. Microalbuminuria was measured in every patient using albumin/creatinin reactive stick in fasting first morning urine. Whenever possible microalbuminuria was confirmed in laboratory by microalbuminuria/creatinina coefficient in first morning urine samples. A total of 979 patients (mean age [SD], 67.9 [10.8] years; 409 men and 570 women, 505 diabetics) were studied. The presence of microalbuminuria was found in 12.4% of hypertensive patients and in 21.4% of diabetic patients (p < 0.001). Hypertensives and normotensive diabetics showed a similar prevalence of microalbuminuria (13.3%, not significant), but it tripled in hypertensive diabetics (33.8; p < 0.01). Glicemic control was not different for microalbuminuric diabetic patients and non microalbuminuric ones. The patients receiving rennin-angiotensin axis blocking drugs do not showed less prevalence of microalbuminuria (hypertensives 10.5%, diabetics 23.5%). Microalbuminuria was confirmed in 65.4% of patients. The prevalence of microalbuminuria in Extremadura seems to be high either in diabetics or non diabetic hypertensive patients. The finding of microalbuminuria in diabetics patients correlates with hypertension but do not with glicemic control. The prevalence of microalbuminuria is high in spite of using rennin-angiotensin axis blocking drugs.

    Despite the previous studies showing the relationship between microalbuminuria and insulin resistance, longitudinal effect of insulin resistance on development of microalbuminuria is not clearly identified in non-diabetic population. One thousand six hundred three non-diabetic Korean men without microalbuminuria in 2005 had been followed up for the development of microalbuminuria until 2010. Microalbuminuria was evaluated by urine-albumin creatinine ration, and insulin resistance was evaluated by homeostasis model assessment of insulin resistance (HOMA-IR). Cox proportional hazards model was used to estimate the risk for microalbuminuria according to the tertile of HOMA-IR. During 5465.8 person-y of average follow-up, microalbuminuria developed in 76 (4.7%) participants. Incidence of microalbuminuria increased in proportion to the level of HOMA-IR (tertile 1: 3.0%, tertile 2: 4.1%, tertile 3: 7.1%, PHOMA-IR was set as reference, hazard ratios and 95% confidence interval were 1.15 (0.56-2.35) and 2.07 (1.05-4.09) for those in the 2nd and 3rd tertiles of HOMA-IR, even after adjusting multiple covariates, respectively (P for linear trend=0.054). Increased insulin resistance was a predictor of microalbuminuria in Korean men. Copyright © 2015 Elsevier B.V. All rights reserved.

    Type 2 diabetes mellitus (T2DM) is a worldwide pandemic that may lead to diabetic kidney disease (DKD), a complication which is the single most important and globally prevalent cause of chronic kidney disease. Microalbuminuria has been shown to be an early indicator of DKD and data suggest that angiotensin receptor blockers (ARBs) reduce urinary albumin excretion and retard the progression of renal disease in hypertensive T2DM patients. However, the effects of ARBs on preventing microalbuminuria and ensuing DKD in normotensive patients with T2DM is yet to be fully established. The objective of this study is to assess the anti-microalbuminuric effects of losartan therapy versus placebo in normotensive T2DM patients. This randomized single blinded controlled trial was performed at the Diabetic Clinic, Jinnah Hospital, Lahore over a period of 10 months. A total of 361 normotensive patients with T2DM and microalbuminuria were selected; of them, 171 patients were randomly allocated to the test group and 190 enrolled into the control group. The patients in the test group were started on losartan 50 mg/day for a six month period while those in the control group were put on vitamin B-12 500 mcg/day. The patients as well as the primary attending physicians/lab evaluators were blinded to the study. All study patients were followed up on a monthly basis. Quantitative microalbuminuria was tested at the beginning and at the end of the study. Out of the 171 patients in the test group, 149 (87.1%) had significant reduction of albuminuria by > 30% of their baseline (mean 101.9 +- 21.7 baseline and, 47.5 + - 12.9 post-therapy). The corresponding values for albuminuria in the 190 patients in the control group was mean 104.7 +- 26.3 baseline and post 6-month mean 103.9 +- 22.9, with P< 0.0001. The anti-albuminuric effect of losartan was reversible as seen on re-checking the urinary albumin two months after discontinuation of treatment. Our study shows that losartan was well tolerated

    Full Text Available Incretin-based therapies represent one of the most promising options in type 2 diabetes treatment owing to their good effectiveness with low risk of hypoglycemia and no weight gain. Other numerous potential beneficial effects of incretin-based therapies have been suggested based mostly on experimental and small clinical studies including its beta-cell- and vasculo-protective actions. One of the recently emerged interesting features of dipeptidyl peptidase-4 (DPP-4 inhibitors is its possible protective effect on the diabetic kidney disease. Here, we review the renal effects of DPP-4 inhibitors with special focus on its influence on the onset and progression of microalbuminuria, as presence of microalbuminuria represents an important early sign of kidney damage and is also associated with increased risk of hypoglycemia and cardiovascular complications. Mechanisms underlying possible nephroprotective properties of DPP-4 inhibitors include reduction of oxidative stress and inflammation and improvement of endothelial dysfunction. Effects of DPP-4 inhibitors may be both glucagon-like peptide-1 (GLP-1 dependent and independent. Ongoing prospective studies focused on the nephroprotective effects of DPP-4 inhibitors will further clarify its possible role in the prevention/attenuation of diabetic kidney disease beyond its glucose lowering properties.

    Results of group therapy (GT) for extreme dental anxiety were compared with individual treatment (IT). Scales used measured dental anxiety, beliefs or trust in dentists, and fear of the next dentist after specialist treatment which showed reduced dental anxiety and improved dental beliefs compared...... with a static control group of 45 patients. The 30 GT patients showed no significant difference in dropouts during training compared with the 68 IT patients, but for patients who completed treatment, GT (n = 24) had greater dental anxiety reduction than IT subjects (n = 60). GT patients required fewer therapist...... hours per patients than did either of the two IT methods, but time saved in GT did not reach significance over clinical rehearsal IT. Results at 1- yr follow-up after specialist treatment indicated that dropouts were significantly greater in group therapy. Rehearsal IT performed best for sustained...

    Full Text Available The R package compareGroups provides functions meant to facilitate the construction of bivariate tables (descriptives of several variables for comparison between groups and generates reports in several formats (LATEX, HTML or plain text CSV. Moreover, bivariate tables can be viewed directly on the R console in a nice format. A graphical user interface (GUI has been implemented to build the bivariate tables more easily for those users who are not familiar with the R software. Some new functions and methods have been incorporated in the newest version of the compareGroups package (version 1.x to deal with time-to-event variables, stratifying tables, merging several tables, and revising the statistical methods used. The GUI interface also has been improved, making it much easier and more intuitive to set the inputs for building the bivariate tables. The ?rst version (version 0.x and this version were presented at the 2010 useR! conference (Sanz, Subirana, and Vila 2010 and the 2011 useR! conference (Sanz, Subirana, and Vila 2011, respectively.

    Albumin excretion in urine is positively correlated with the presence of ischemic heart disease and atherosclerotic risk factors. We studied prospectively whether a slight increase of urinary albumin excretion, ie, microalbuminuria, adds to the increased risk of ischemic heart disease among...... hypertensive subjects. In 1983 and 1984, blood pressure, urinary albumin/creatinine concentration ratio, plasma total and HDL cholesterol levels, body mass index, and smoking status were obtained in a population-based sample of 2085 subjects, aged 30 to 60 years, who were free from ischemic heart disease......, diabetes mellitus, and renal or urinary tract disease. Untreated arterial hypertension or borderline hypertension was present in 204 subjects, who were followed until 1993 by the National Hospital and Death Certificate Registers with respect to development of ischemic heart disease.

    Whether changes over time of urinary albumin excretion have prognostic value is a matter of discussion. The objective was to assess the prognostic value of changes in urinary albumin excretion over time in cardiovascular risk during antihypertensive treatment. Follow-up study of 2835 hypertensives in the absence of previous cardiovascular disease (mean age 55 years, 47% men, BP 138/80 mm Hg, 19.1% diabetics, and calibrated systemic coronary risk estimation 5 or >10.6%). Usual-care of antihypertensive treatment was implemented to maintain blood pressure<140/90 mm Hg. Urinary albumin excretion was assessed yearly, and the values were expressed as the creatinine ratio. Incidence of cardiovascular events, fatal and nonfatal, was recorded during the follow-up. During a median follow-up of 4.7 years (17 028 patients-year), 294 fatal and first nonfatal cardiovascular events were recorded (1.73 CVD per 100 patients/year). Independently of blood pressure, estimated glomerular filtration rate, level of cardiovascular risk, and antihypertensive treatment, microalbuminuria at baseline and at any time during the follow-up resulted in higher risk for events, hazard ratio (HR) 1.35 (95% confidence interval [CI], 1.08-1.79) and HR 1.49 (95% CI, 1.14-1.94), respectively. Likewise, development of microalbuminuria (HR 1.60; 95% CI, 1.04-2.46) or persistence from the beginning (1.53; 95% CI, 1.13-2.06) had a significantly higher rate of events than if remained normoalbuminuric (HR 1) or regress to normoalbuminuria (HR 1.37; 95% CI, 0.92-2.06) with an 18%, 18%, 8%, and 11% events, respectively, P<0.001. The study supports the value of urinary albumin excretion assessment as a prognostic factor for cardiovascular risk, but also opens the way to consider it as an intermediate objective in hypertension. © 2014 American Heart Association, Inc.

    To compare the psychosocial outcomes of the CenteringPregnancy (CP) model of group prenatal care to individual prenatal care, we conducted a prospective cohort study of women who chose CP group (N = 124) or individual prenatal care (N = 124). Study participants completed the first survey at study recruitment (mean gestational age 12.5 weeks), with 89% completing the second survey (mean gestational age 32.7 weeks) and 84% completing the third survey (6 weeks' postpartum). Multiple linear regression models compared changes by prenatal care model in pregnancy-specific distress, prenatal planning-preparation and avoidance coping, perceived stress, affect and depressive symptoms, pregnancy-related empowerment, and postpartum maternal-infant attachment and maternal functioning. Using intention-to-treat models, group prenatal care participants demonstrated a 3.2 point greater increase (p prenatal planning-preparation coping strategies. While group participants did not demonstrate significantly greater positive outcomes in other measures, women who were at greater psychosocial risk benefitted from participation in group prenatal care. Among women reporting inadequate social support in early pregnancy, group participants demonstrated a 2.9 point greater decrease (p = 0.03) in pregnancy-specific distress in late pregnancy and 5.6 point higher mean maternal functioning scores postpartum (p = 0.03). Among women with high pregnancy-specific distress in early pregnancy, group participants had an 8.3 point greater increase (p prenatal planning-preparation coping strategies in late pregnancy and a 4.9 point greater decrease (p = 0.02) in postpartum depressive symptom scores. This study provides further evidence that group prenatal care positively impacts the psychosocial well-being of women with greater stress or lower personal coping resources. Large randomized studies are needed to establish conclusively the biological and psychosocial benefits of group

    Full Text Available BackgroundRecent evidence has suggested an association between subclinical hypothyroidism (SCH and microalbuminuria in patients with type 2 diabetes. However, whether SCH is related to microalbuminuria among subjects with prediabetes has not been studied. Thus, we evaluated the association between SCH and microalbuminuria in a cohort of prediabetic Egyptian adults.MethodsA total of 147 prediabetic subjects and 150 healthy controls matched for age and sex were enrolled in this study. Anthropometric measurements, plasma glucose, lipid profile, homeostasis model assessment of insulin resistance (HOMA-IR, thyroid stimulating hormone (TSH, free thyroxine, triiodothyronine levels, and urinary albumin-creatinine ratio (UACR were assessed.ResultsThe prevalence of SCH and microalbuminuria in the prediabetic subjects was higher than that in the healthy controls (16.3% vs. 4%, P<0.001; and 12.9% vs. 5.3%, P=0.02, respectively. Prediabetic subjects with SCH were characterized by significantly higher HOMA-IR, TSH levels, UACR, and prevalence of microalbuminuria than those with euthyroidism. TSH level was associated with total cholesterol (P=0.05, fasting insulin (P=0.01, HOMA-IR (P=0.01, and UACR (P=0.005. UACR was associated with waist circumference (P=0.01, fasting insulin (P=0.05, and HOMA-IR (P=0.02. With multiple logistic regression analysis, SCH was associated with microalbuminuria independent of confounding variables (β=2.59; P=0.01.ConclusionOur findings suggest that prediabetic subjects with SCH demonstrate higher prevalence of microalbuminuria than their non-SCH counterparts. SCH is also independently associated with microalbuminuria in prediabetic subjects. Screening and treatment for SCH may be warranted in those patients.

    Sexuality usually decreases during pregnancy. To evaluate sexual behavior during pregnancy, comparing two groups. One had sexual education and the other had none. After randomizing two groups of pregnant women, they completed self-administered questionnaires regarding attitudes and sexual behavior before and during pregnancy. Sexual education was provided in one group and a second self-administered questionnaire was completed 12 weeks later. Responses were summarized using descriptive statistics. Comparison of change of sexual behavior between two groups was analyzed using chi-square and student t-tests. The change in frequency of coitus during pregnancy was compared between the sexual education group and the noneducation group. There was no statistically difference in changes of sexual behavior between the two groups. There was a reduction in frequency of coitus (90.6% vs. 94.9%, P>0.05) between the nonsexual education group and the sexual education group and no statistically significant change in mean reduction of sexual desire (8.9 vs. 4.4, P>0.05), sexual arousal (14.3 vs. 13.1, P>0.05), satisfaction from coitus (15.4 vs. 7.2, P>0.05), and orgasm from coitus (12.3 vs. 12.3, P>0.05). The change of sexual behavior during pregnancy in the sexual education group was not different from that in the nonsexual education group. © 2010 International Society for Sexual Medicine.

    Increased arterial stiffness (iAS) and microalbuminuria (MAU), which may occur simultaneously or separately in the general population and share similar risk factors, are markers of macro- and microvascular injuries. Our research investigated the comorbidity of iAS and MAU in the middle-aged population and examined the heterogeneous effects of metabolic risk factors on iAS and MAU. We selected 11,911 individuals aged 45 to 60 years who underwent a health examination at the 3rd Xiangya Hospital between 2010 and 2014. Metabolic syndrome (MetS) was determined according to IDF/NHLBI/AHA-2009 criteria. Multinomial logistic regression was applied to evaluate the influence of MetS, components of MetS and clusters of MetS on the co-occurrence (MAU(+)/iAS(+)) or non-co-occurrence (MAU(+)/iAS(-) and MAU(-)/iAS(+)) of MAU and iAS. Reference group was MAU(-)/iAS(-). A positive effect of MetS on the presence of MAU(+)/iAS(-), MAU(-)/iAS(+), or MAU(+)/iAS(+) is listed in ascending order based on odds ratios (ORs = 2.11, 2.41, 4.61, respectively; P iAS(-), Elevated blood pressure (BP) (OR = 1.62 vs. 4.83, P iAS(+), whereas fasting blood glucose (FBG) was less associated (OR = 1.37 vs. 1.31, P 4, P iAS(-). Compared with the individuals without MetS, individuals with the elevated BP, FBG, TG and decreased HDL-c cluster had the greatest likelihood of presenting a MAU(-)/iAS(+) (OR = 5.98, P iAS(+) (OR = 13.17, P iAS(+) (OR = 5.22, P iAS, these influences could be selectively targeted to identify different types of vascular injuries.

    Numerical data that are normally distributed can be analyzed with parametric tests, that is, tests which are based on the parameters that define a normal distribution curve. If the distribution is uncertain, the data can be plotted as a normal probability plot and visually inspected, or tested for normality using one of a number of goodness of fit tests, such as the Kolmogorov-Smirnov test. The widely used Student's t-test has three variants. The one-sample t-test is used to assess if a sample mean (as an estimate of the population mean) differs significantly from a given population mean. The means of two independent samples may be compared for a statistically significant difference by the unpaired or independent samples t-test. If the data sets are related in some way, their means may be compared by the paired or dependent samples t-test. The t-test should not be used to compare the means of more than two groups. Although it is possible to compare groups in pairs, when there are more than two groups, this will increase the probability of a Type I error. The one-way analysis of variance (ANOVA) is employed to compare the means of three or more independent data sets that are normally distributed. Multiple measurements from the same set of subjects cannot be treated as separate, unrelated data sets. Comparison of means in such a situation requires repeated measures ANOVA. It is to be noted that while a multiple group comparison test such as ANOVA can point to a significant difference, it does not identify exactly between which two groups the difference lies. To do this, multiple group comparison needs to be followed up by an appropriate post hoc test. An example is the Tukey's honestly significant difference test following ANOVA. If the assumptions for parametric tests are not met, there are nonparametric alternatives for comparing data sets. These include Mann-Whitney U-test as the nonparametric counterpart of the unpaired Student's t-test, Wilcoxon signed-rank test

    Brain network analyses have moved to the forefront of neuroimaging research over the last decade. However, methods for statistically comparing groups of networks have lagged behind. These comparisons have great appeal for researchers interested in gaining further insight into complex brain function and how it changes across different mental states and disease conditions. Current comparison approaches generally either rely on a summary metric or on mass-univariate nodal or edge-based comparisons that ignore the inherent topological properties of the network, yielding little power and failing to make network level comparisons. Gleaning deeper insights into normal and abnormal changes in complex brain function demands methods that take advantage of the wealth of data present in an entire brain network. Here we propose a permutation testing framework that allows comparing groups of networks while incorporating topological features inherent in each individual network. We validate our approach using simulated data with known group differences. We then apply the method to functional brain networks derived from fMRI data.

    Full Text Available Background: Microalbuminuria and serum creatinine are the specific markers of acute renal injury. Perinatal asphyxia is responsible for 50% of all neonatal deaths and nonoliguric acute renal injuryis one of its complications. This study was undertaken to determine the efficacy of serum creatinine and microalbuminuria for early diagnosis of renal injury in severely asphyxiated neonates in Calabar, Nigeria.Methods: This prospective cross-sectional study was performed among severely asphyxiated newborns admitted into the neonatal wards of the University of Calabar Teaching Hospital (UCTH. Standard methods for the determination of blood urea and electrolyte were executed. Micral-test strips have been applied using urine dipstick and the result of the test was negative only for albumin. The developed colors have been compared five minutes after the first test.Results: Fifty full-term newborns were enrolled and their serum electrolytes, creatinine and the creatinine clearance were essentially normal. Six neonates demonstrated positive results in the microalbominuria assessment, while the rest were negative in this regard. The test has 0% sensitivity and 100% specificity, while the positive and negative predictive values were 0% and 88%, respectively.Conclusion: Microalbuminuria is not a useful marker for early diagnosis of acute renal failure in the newborns with severe prenatal asphyxia, but further studies are recommended.

  10. Energy policy: Comparative effects on minority population groups

    For a number of years, analyses of minority household energy demand have been supported by the United States Department of Energy (DOE), Office of Economic Impact and Diversity (formerly the Office of Minority Economic Impact). The intention of these analyses has been to characterize patterns of energy demand by various demographic, regional and socioeconomic groups and to develop analytical tools to assess the distributive impact of energy prices and policy on these groups. The model supports strategic objectives outlined by the Department of Energy to explicitly recognize and promote equity in state public utility commission decisions and to assess the potential impact of federal and state energy policy on demographically diverse groups as reported in the Department`s Annual Energy Outlook and the upcoming National Energy Policy Plan. The legislation mandating the Office of Economic Impact and Diversity had been premised on the assumption that patterns of energy demand for minority households are different from the population as a whole. Determining the validity of this premise and its potential economic impact on different population groups has been a major objective of these analyses. Consequently, the recripriocal impacts of energy policy on demographic groups and energy consumption and expenditure dynamics on policy formulation and strategy is a central objective of these studies. Residential energy demand research has been substantial in the past twenty years. Insightful and useful research has been done in this area. However, none of this research has addressed the potential differences in the residential energy demand structure among various population groups. Recent work does compare energy and electricity demand elasticities for non-Latino Whites, with the demand elasticities for Latinos and Blacks. This research is particularly important for examination of questions related to the economic welfare implications of national energy policy.

  11. Social Spirals through Everyday Group Life: Settings and Group Styles in a Comparative Perspective

    Directory of Open Access Journals (Sweden)

    Sebastiano Citroni

    2018-01-01

    Full Text Available Everyday group life is generally neglected in the study of the ongoing shifts affecting voluntary associations. This paper is grounded on a comparative ethnography of three Milanese associations affected by transformations in forms of voluntary participation, repertoires of action, and in their relations with public institutions. The study focuses on group styles and settings to ascertain the role played by everyday group life in shaping the implications of these transformations for the production of inclusive outcomes by the observed associations. The author introduces three different results produced by the studied associations and account for them with the same overall argument, which focus on practices and spaces shaping everyday group life. The main findings illustrate that everyday group life works both as a filter through which transformations produce consequences and also as a site of autonomous elaboration through which associations’ outcomes are made and unmade.

    Objectives The aim of the present study was to assess comparative emergency department (ED) resource utilisation across age groups. Methods A retrospective analysis of data collected in the National Non-admitted Patient Emergency Department Care Database was undertaken to assess comparative ED resource utilisation across six age groups (0-14, 15-35, 36-64, 65-74, 75-84 and ≥85 years) with previously used surrogate markers of ED resource utilisation. Results Older people had significantly higher resource utilisation for their individual ED episodes of care than younger people, with the effect increasing with advancing age. Conclusion With ED care of older people demonstrated to be more resource intensive than care for younger people, the projected increase in older person presentations anticipated with population aging will have a magnified effect on ED services. These predicted changes in demand for ED care will only be able to be optimally managed if Australian health policy, ED funding instruments and ED models of care are adjusted to take into account the specific care and resource needs of older people. What is known about the topic? Current Australian ED funding models do not adjust for patient age. Several regional studies have suggested higher resource utilisation of ED patients aged ≥65 years. Anticipated rapid population aging mandates that contribution of age to ED visit resource utilisation be further explored. What does this paper add? The present study of national Australian ED presentations compared ED resource utilisation across age groups using surrogate markers of ED cost. Older people were found to have significantly higher resource utilisation in the ED, with the effect increasing further with advancing age. What are the implications for practitioners? The higher resource utilisation of older people in the ED warrants a review of current ED funding models to ensure that they will continue to meet the needs of an aging population.

    In patients with systemic hypertension, microalbuminuria is a marker of endothelial damage and is associated with an increased risk for cardiovascular disease. To determine the factors that may lead to the occurrence of microalbuminuria in hypertensive patients with serum creatinine lower than 1.5 mg/dL. This cross-sectional study included 133 Brazilians with essential hypertension followed up at a hypertension outpatient clinic. Those with serum creatinine higher than 1.5 mg/dL, as well as those with diabetes mellitus, were excluded. Systolic and diastolic blood pressures were measured, and body mass index (BMI) and GFR estimated by using the CKD-EPI formula were calculated. The serum levels of the following were assessed: CysC, creatinine, total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, C-reactive protein (CRP) and fasting glucose. Microalbuminuria was determined in 24-hour urine. Hypertensive patients were classified according to the presence of one or more criteria for metabolic syndrome. In a multiple regression analysis, the serum levels of CysC and CRP, the atherogenic index log TG/HDLc and the presence of three or more criteria for metabolic syndrome were positively correlated with microalbuminuria (r{sup 2}: 0.277, p < 0.05). CysC, CRP, log TG/HDLc, and the presence of three or more criteria for metabolic syndrome, regardless of serum creatinine, were associated with microalbuminuria, an early marker of kidney damage and cardiovascular risk in patients with essential hypertension.

    Maternal diabetes has assumed epidemic relevance in recent years and animal studies have provided some evidence that it may cause abnormalities in renal development and a reduction in nephron endowment in the offspring; however, human data are lacking. The renal cortex contains ∼95% of the glomeruli and its volume could be taken as a surrogate measure of glomerular number; based on this assumption, we measured renal cortex volume and in addition, microalbuminuria in a homogeneous sample of 42 children of diabetic (pregestational, n = 13, and gestational, n = 29) mothers, compared with 21 healthy children born of non-diabetic mothers. The offspring of diabetic mothers showed a significant reduction of renal cortex volume and higher albumin excretion compared with controls, possibly attributable to a reduction in the number of nephrons and the difference was statistically significant (P < 0.001). Although further studies on a larger sample are necessary, our preliminary findings suggest that maternal diabetes may affect renal development with sequelae later in life, requiring closer monitoring and follow-up. Furthermore, the importance of strict maternal diabetes management and control must be emphasized.

    We explored whether visit-to-visit variability in both glycated hemoglobin (HbA1c) and systolic blood pressure (SBP) simultaneously predicted the development of microalbuminuria and retinopathy, and whether the predictive ability of these measurements changed according to mean HbA1c and SBP levels in people with type 2 diabetes. A retrospective observational cohort study was conducted on 243 type 2 diabetes patients with normoalbuminuria and 486 without retinopathy at the first visit and within 1year thereafter. The two cohorts were followed up from 1995 until 2012. Multivariate and stratified analyses were performed using Cox proportional hazard models. Microalbuminuria developed in 84 patients and retinopathy in 108. Hazard ratios (HRs) for the development of microalbuminuria associated with the coefficient of variation (CV) and variation independent of mean (VIM) of both HbA1c and SBP significantly increased. In participants with a mean SBP HbA1c were abruptly elevated and significant compared with those with a mean SBP ≥130mmHg. Visit-to-visit variability in both HbA1c and SBP simultaneously predict the development of microalbuminuria. HbA1c variability may predict the development of retinopathy when the mean SBP is normal (<130mmHg). Copyright © 2017 Elsevier B.V. All rights reserved.

    Microalbuminuria (MA) is considered a major risk factor predisposing to cardiovascular morbidity and mortality. Outcomes after percutaneous coronary intervention (PCI) for patients with acute myocardial infarction (AMI) complicated by MA have been well described. However, data regarding admission MA and coronary and myocardial flow are scant. The aims of this study were to evaluate the effects of admission MA on coronary blood flow and prognosis in ST-segment elevation myocardial infarction (STEMI) patients undergoing primary PCI. Did elevated admission microalbuminuria predict poor myocardial blood flow and 6-month mortality in ST-segment elevation myocardial infarction patients undergoing primary percutaneous coronary intervention? A total of 247 patients undergoing primary PCI for STEMI within 12 hours after symptom onset were studied. Patients were divided into 2 groups according to admission urinary albumin extraction rate (UAER): (1) an MA group (UAER 20-200 µg/min), and (2) a normoalbuminuria (NA) group (UAER < 20 µg/min). Microalbuminuria was observed in 108 patients. Univariate analyses showed statistical differences between the NA and MA groups in serum creatine level, plasma glucose level, and peak creatine kinase level on presentation. Thrombolysis In Myocardial Infarction (TIMI) flow grades (TFGs) 0-2 in the MA group were more frequent (9.4% vs 21.2%, P < 0.05) than in the NA group, and corrected TIMI frame count was higher (23.9 ± 18.5 vs 29.8 ± 23.5, P < 0.05). Admission MA was an independent predictor of poor myocardial perfusion (adjusted relative risk: 3.14, 95% confidence interval: 0.99-6.78) and a higher rate of 6-month mortality in STEMI patients undergoing primary PCI (adjusted relative risk: 1.58, 95% confidence interval: 0.74-3.39). Admission MA levels are associated with impaired myocardial flow and poor prognosis in STEMI patients undergoing primary PCI. © 2012 Wiley Periodicals, Inc.

    Full Text Available Categorical variables are commonly represented as counts or frequencies. For analysis, such data are conveniently arranged in contingency tables. Conventionally, such tables are designated as r × c tables, with r denoting number of rows and c denoting number of columns. The Chi-square (χ2 probability distribution is particularly useful in analyzing categorical variables. A number of tests yield test statistics that fit, at least approximately, a χ2 distribution and hence are referred to as χ2 tests. Examples include Pearson′s χ2 test (or simply the χ2 test, McNemar′s χ2 test, Mantel-Haenszel χ2 test and others. The Pearson′s χ2 test is the most commonly used test for assessing difference in distribution of a categorical variable between two or more independent groups. If the groups are ordered in some manner, the χ2 test for trend should be used. The Fisher′s exact probability test is a test of the independence between two dichotomous categorical variables. It provides a better alternative to the χ2 statistic to assess the difference between two independent proportions when numbers are small, but cannot be applied to a contingency table larger than a two-dimensional one. The McNemar′s χ2 test assesses the difference between paired proportions. It is used when the frequencies in a 2 × 2 table represent paired samples or observations. The Cochran′s Q test is a generalization of the McNemar′s test that compares more than two related proportions. The P value from the χ2 test or its counterparts does not indicate the strength of the difference or association between the categorical variables involved. This information can be obtained from the relative risk or the odds ratio statistic which is measures of dichotomous association obtained from 2 × 2 tables.

    Full Text Available Background. One of the severest complications of diabetes is diabetic kidney disease (DKD. Microalbuminuria (MAU is one of the first signals of DKD and an important pathogenetic mechanism of disease progression. With diabetes dramatically antioxidant properties worsen. Objective. The aim was to investigate the effect of L-arginine on oxidative stress parameters and microalbuminuria in type 2 diabetes mellitus and chronic kidney disease patients. Methods. Total of 57 patients with type 2 diabetes mellitus and chronic kidney disease and 30 healthy subjects (control group were included in the study. The patients were divided into 2 congruent groups. The 1-st group of patients (n=33, in addition to standard therapy, received L-arginine 4.2 g intravenously for 5 days, after that they took it 1,0 g orally three times a day during meals for 1 month. The second group of patients (n=24 received a standard therapy. The concentration of lipid peroxidation products was measured by a spectrophotometric method. The determination of MAU was carried out in morning portion of urine immunological semiquantitative using test strips. Results. Significant improvement in indexes of lipid peroxidation was observed in both groups after therapy (p˂0.01, but in patients treated with L-arginine it was more expressed (p˂0,01. The standard therapy did not significantly affect the level of MAU (p˃0,05. The patients treated with L-Arginine, showed a significant reduction in MAU (p˂0.01. Conclusions. The usage of L-arginine facilitates the correction of lipid peroxidation processes and reduces the severity of microalbuminuria in patients with diabetic kidney disease that slowing its progression.

    To analyze the content and culture of anorexia nervosa (AN)-related communication on the current major social network site (SNS) Facebook. We searched for groups and sites related to AN on Facebook by means of a faux profile of a young female. Identified groups/sites were analyzed with respect to (1) category (education, self-help, professional help, pro-ana, anti pro-ana), (2) activity, (3) motivational aspects (prose, pictures), and (4) social support. Numerous relevant groups were found in all categories except that professional help was almost nonexistent. Pro-ana groups were found to be the most active, best organized, and offered the highest levels of social support. Prose motivation was distinctly offered in all categories. Motivation with pictures was particularly evident in pro-ana groups. The most functional motivation was found in self-help groups. SNS appears to be a relevant way for young females suffering from AN to communicate and exchange disease and health-related ideas. Caregivers, researchers, and institutions in the field of eating disorders should be aware of the existence, possibilities, dysfunctions, and influence of SNS. Whether SNS can help persons with AN to get therapeutic assistance as well as whether it can be integrated into psychotherapeutic strategies should be examined in future studies.

    The objective of the present study was to assess the regression of left ventricular hypertrophy (LVH) during antihypertensive treatment, and its relationship with the changes in microalbuminuria. One hundred and sixty-eight previously untreated patients with echocardiographic LVH, 46 (27%) with microalbuminuria, were followed during a median period of 13 months (range 6-23 months) and treated with lifestyle changes and antihypertensive drugs. Twenty-four-hour ambulatory blood pressure monitoring, echocardiography and urinary albumin excretion were assessed at the beginning and at the end of the study period. Left ventricular mass index (LVMI) was reduced from 137 [interquartile interval (IQI), 129-154] to 121 (IQI, 104-137) g/m (P 50%) had the same odds of achieving regression of LVH as patients with normoalbuminuria (ORm 1.1; 95% CI 0.38-3.25; P = 0.85). However, those with microalbuminuria at baseline, who did not regress, had less probability of achieving LVH regression than the normoalbuminuric patients (OR 0.26; 95% CI 0.07-0.90; P = 0.03) even when adjusted for age, sex, initial LVMI, GFR, blood pressure and angiotensin-converting enzyme inhibitor (ACE-I) or angiotensin receptor blocker (ARB) treatment during the follow-up. Patients who do not have a significant reduction in microalbuminuria have less chance of achieving LVH regression, independent of blood pressure reduction.

    In type 2 diabetes mellitus, heart failure is a frequent, potentially fatal and often forgotten complication. Glucose-lowering agents and adjuvant therapies modify the risk of heart failure. We recently reported that 7.8 years of intensified compared with conventional multifactorial intervention in individuals with type 2 diabetes and microalbuminuria in the Steno-2 study reduced the risk of cardiovascular disease and prolonged life over 21.2 years of follow-up. In this post hoc analysis, we examine the impact of intensified multifactorial intervention on the risk of hospitalisation for heart failure. One hundred and sixty individuals were randomised to conventional or intensified multifactorial intervention, using sealed envelopes. The trial was conducted using the Prospective, Randomised, Open, Blinded Endpoints (PROBE) design. After 7.8 years, all individuals were offered intensified therapy and the study continued as an observational follow-up study for an additional 13.4 years. Heart-failure hospitalisations were adjudicated from patient records by an external expert committee blinded for treatment allocation. Event rates were compared using a Cox regression model adjusted for age and sex. Eighty patients were assigned to each treatment group. Ten patients undergoing intensive therapy vs 24 undergoing conventional therapy were hospitalised for heart failure during follow-up. The HR (95% CI) was 0.30 (0.14, 0.64), p = 0.002 in the intensive-therapy group compared with the conventional-therapy group. Including death in the endpoint did not lead to an alternate overall outcome; HR 0.51 (0.34, 0.76), p = 0.001. In a pooled cohort analysis, an increase in plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) during the first two years of the trial was associated with incident heart failure. Intensified, multifactorial intervention for 7.8 years in type 2 diabetic individuals with microalbuminuria reduced the risk of hospitalisation for heart

    2013-06-25

    This manuscript provides insights into ongoing debates on the regulatory issues surrounding groups of biotechnology-driven 'New Plant Breeding Techniques' (NPBTs). It presents the outcomes of preliminary discussions and in some cases the initial decisions taken by regulators in the following countries: Argentina, Australia, Canada, EU, Japan, South Africa and USA. In the light of these discussions we suggest in this manuscript a structured approach to make the evaluation more consistent and efficient. The issue appears to be complex as these groups of new technologies vary widely in both the technologies deployed and their impact on heritable changes in the plant genome. An added complication is that the legislation, definitions and regulatory approaches for biotechnology-derived crops differ significantly between these countries. There are therefore concerns that this situation will lead to non-harmonised regulatory approaches and asynchronous development and marketing of such crops resulting in trade disruptions.

    Transient ischemic attacks (TIA) and minor strokes are important risk factors for recurrent strokes. Current stroke risk prediction scores such as ABCD2, although widely used, lack optimal sensitivity and specificity. Elevated urinary albumin excretion predicts cardiovascular disease, stroke, and mortality. We explored the role of microalbuminuria (using albumin creatinine ratio (ACR)) in predicting recurrence risk in patients with TIA and minor stroke. Urinary ACR was measured on a spot sample in 150 patients attending a daily stroke clinic with TIA or minor stroke. Patients were followed up at day 7, 30, and 90 to determine recurrent stroke, cardiovascular events, or death. Eligible patients had a carotid ultrasound Doppler investigation. High-risk patients were defined as those who had an event within 90 days or had >50% internal carotid artery (ICA) stenosis. Fourteen (9.8%) recurrent events were reported by day 90 including two deaths. Fifteen patients had severe ICA stenosis. In total, 26 patients were identified as high risk. These patients had a higher frequency of previous stroke or hypercholesterolemia compared to low-risk patients (P = 0.04). ACR was higher in high-risk patients (3.4 [95% CI 2.2-5.2] vs. 1.7 [1.5-2.1] mg/mmol, P = 0.004), independent of age, sex, blood pressure, diabetes, and previous stroke. An ACR greater than 1.5 mg/mmol predicted high-risk patients (Cox proportional hazard ratio 3.5 (95% CI 1.3-9.5, P = 0.01). After TIA or minor stroke, a higher ACR predicted recurrent events and significant ICA stenosis. Incorporation of urinary ACR from a spot sample in the acute setting could improve risk stratification in patients with TIA and minor stroke.

    Subclinical elevation of urinary albumin excretion (UAlbE) early in the course of diabetes mellitus has been suggested to predict later clinical proteinuria and mortality. UAlbE is currently measured using radioimmunoassay (RIA) or radial immunodiffusion methods. However, these procedures are expensive and time-consuming and cannot be used as screening methods. Recently, an agglutination test (AT) has been suggested as a routinary method for the screening of microalbuminuria in diabetic patients. In this paper the results obtained are compared with an AT procedure and RIA method in a screening program of microproteinuria in diabetic patients. An immunological test (a latex agglutination assay) for the analysis of albuminura is used, which human albumin was adsorbed to latex beads (about 0.3 μl of a urine sample. Urine samples containing an albumin concentration >40 μg/ml were found to inhibit the agglutination of latex beads with antiserum. The RIA and AT results showed good agreement when urine samples were assayed soon after collection or after a short period of storage (≤3 weeks at -20 grade centigrades). The AT procedure has been adjusted in order to give a positive response (no agglutination) over the range of supranormal concentrations of urinary albumin (>40 μg/ml), which are on the other hand undetectable by Albustix. In addition, it is possible to perform a semiquantitative test using various dilutions of urine samples with albumin concentration > 40 μg/ml, so to estimate approximately the UAlbE. The AT method is simple, fast and specific, and has proved to be useful for the identification of diabetic patients at risk for developing clinical nephropathy. Therefore, it may be used in screening programs for diabetic microproteinuria

    Full Text Available Abstract Background Diabetic subjects, especially women, show high prevalence of asymptomatic bacteriuria (ASB. The aim of the present study was to evaluate the prevalence of ASB in subjects with type 2 diabetes mellitus (T2D with and without microalbuminuria (MA. Findings A hundred diabetic subjects with MA (53 males/47 females, mean age ± standard deviation: 65.5 ± 11.1 years and 100 diabetic subjects without MA (52 males/48 females, mean age ± standard deviation: 65.4 ± 11.3 years, consecutively attending the outpatient diabetes clinic of our hospital were recruited in the study. Subjects with overt diabetic nephropathy or nephropathy from other causes were excluded. In addition, subjects with symptoms of urinary track infection or use of antimicrobial drugs in the last 14 days were excluded by the study. Diabetic subjects with MA showed increased prevalence of ASB compared to diabetic subjects without MA (21% versus 8%, P Escherichia coli was the most prevalent pathogen isolated in diabetic subjects with and without MA (12% versus 3.0%, P = 0.01, respectively followed by Proteus mirabilis (6% versus 5%, P = 0.75, respectively and Klebsiella spp (5% versus 1%, P = 0.09, respectively.

Out of 3065 patients, 1173 (38.3%) were in the HTN group without T2DM (HTN) and 1892 (61.7%) in the HTN group with T2DM (HTN+T2DM). The overall prevalence of MA was 50.6% determined by MicralA and 22.1% with MA-24 h. Urinary albumin excretion data obtained by both techniques correlated significantly (r s =0.586; Pvalue of 41% and negative predictive value of 97%. With both methods, the presence of MA was independently associated with a higher risk (1.5- to 2.9-fold) of CV and renal organ damage in both HTN and HTN+T2DM groups. MicralA, due to its high sensitivity and negative predictive value, can be considered as a valid and reliable method for MA screening in patients with HTN with/without T2DM.

    for coronary artery disease, especially when associated with microalbuminuria (MA. Structural and functional changes in lipoproteins have not yet been fully elucidated in this context. OBJECTIVE: To assess lipid transfer (T to HDL in type-2 diabetic patients and its association with microalbuminuria and treatment with statins or insulin. METHODS: Thirty-three patients with type-2 diabetes mellitus and 34 age-matched control subjects were studied. A synthetic cholesterol-rich nanoemulsion radiolabeled with ³H- triglycerides (TG and 14C-free cholesterol (FC or ³H- cholesteryl ester (CE and 14C-phospholipids (PL was incubated with plasma. Both the nanoemulsion and lipoproteins were precipitated, except for HDL, which was counted for radioactivity. RESULTS: PLT (% was higher in the T2DM group than in the control group (25.2 ± 3.2 and 19.7 ± 3.2 respectively; p < 0.001, as was free cholesterol (% FC: 9.1 ± 2.7 and 6.3 ± 1.5 respectively; p < 0.001. The diagnosis of microalbuminuria (MA was not associated with changes in lipid transfers. Insulin therapy was associated with lower PLT rates: 23.5 ± 2.1 versus 26.1 ± 3.3; p = 0.018. Statin therapy, in turn, was associated with a drop in all lipid transfers - CET 3.5 ± 0.9; PLT: 23.8 ± 2.0; TGT: 3.9 ± 0.8; FCT: 7.4 ± 1.3 - as compared to the group that was not on statin therapy (CET: 5.9 ± 2.4; PLT: 26.9 ± 3.6; TGT: 6.4 ± 2.2; FCT: 11.1 ± 2.6. CONCLUSION:Type-2 diabetes mellitus increased lipid transfer to HDL particles, whereas statin therapy decreased all lipid transfers. The presence of MA was not associated with changes in lipid transfer.

    To quantify PH prevalence in primiparous adolescents; define predictive factors for the occurrence of PH and its impact on newborns. We followed 29 primiparous adolescents from the prenatal period through the 12th week of the puerperium, with a mean of sixteen years of age, served at the Outpatient Facility for Adolescents of Maternidade Escola Assis Chateaubriand (MEAC) of Universidade Federal do Ceará (Fortaleza, Brazil). The pregnant adolescents were divided into two groups, that is, those who remained normotensive (Group I) and those who developed PH (Group II). The variables investigated in the assessment of the value of predictability for the development of PH were anthropometric measures, socioeconomic aspects, smoking habit, inheritance for SAH (father/mother), prenatal tests requested in the first prenatal care visit in addition to microalbuminuria and ambulatory blood pressure monitoring (ABPM) in the 28th week of gestation. The pregnant adolescents were followed up at delivery and late puerperium (12th week after the puerperium). The newborns to the mothers included in our study were assessed at birth according to the Apgar score and the Capurro method, for weight, height and perinatal hypoxia. The prevalence of PH was 51.7%. Inheritance for SAH presented the highest predictive value for PH with an odds ratio of 10.99. Diastolic arterial pressure equal to or above 70 mmHg at the gestational age of 35 weeks was statistically significant as a predictive value for PH. At ABPM we found a predictive value for PH: diastolic pressure load during alertness, diastolic and systolic pressure load during night sleep, pressure variability and maximum diastolic pressure during sleep. Specifically a maximum diastolic arterial pressure (DAP) at ABPM during the period of night sleep (3)64 mmHg presented an odds ratio of 6 for PH with a sensitivity of 80% and a specificity of 60% for the development of PH.

    In type 2 diabetes elevated glomerular filtration rate (GFR) and increased renal volume (RV), often accompanied to normo or microalbuminuria, were demonstrated. This condition is considered a pathogenetic factor for clinical nephropathy. As this topic is little studied in type 2 diabetes, we have investigated 73 type 2 diabetic patients (34 normo and 39 microalbuminuric), looking for a correlation between GFR, RV, hypertension, duration of diabetes and indexes of metabolic control. GFR was measured by a scintigraphy, after infusion of 99Tc-DTPA. Renal volume was determined by ultrasound scanning. Between the groups GFR and RV weren't different; elevated GFR was demonstrated in 3 patients; increased RV in 1 patient. In the hypertensive group GFR was lower than in normotensive group and in controls. Multivariate analysis in stepwise demonstrated that GFR presents a negative correlation to systolic blood pressure as in normo as in microalbuminuric patients. In the normotensive group GFR didn't correlate to the other variables. The present data suggest that in type 2 diabetes there is a little prevalence of glomerular hyperfiltration and increased renal volume and that hypertension plays a role on GFR of hypertensive diabetic patients.

    Full Text Available INTRODUCCIÓN. La diabetes mellitus de tipo 1 es una enfermedad autoinmunitaria que se caracteriza por una deficiencia absoluta de la producción de insulina, alteraciones del metabolismo de la glucosa, los lípidos y las proteínas. El objetivo de nuestra investigación fue conocer la relación entre dislipidemia y lesión renal diabética, expresada por la presencia de microalbuminuria. MÉTODOS. Se estudiaron 52 niños con diabetes mellitus de tipo 1, edades de 9 a 15 años y 2 años o más de duración de la enfermedad. A todos se les realizó lipidograma en ayunas que incluyó análisis de triglicéridos, colesterol total, colesterol de las lipoproteínas de baja densidad y colesterol de las lipoproteínas de alta densidad. Se realizaron pruebas de microalbuminuria mediante radioinmunoanálisis para la albúmina humana en orina y también filtrado glomerular. RESULTADOS. Se observó dislipidemia en 30 pacientes (57 % y disminución del colesterol de lipoproteínas de alta densidad en todos los pacientes dislipidémicos. Se constató un aumento del colesterol de lipoproteínas de baja densidad en 27 casos (51,9 %; el colesterol total estaba elevado en 12 (23 % y se comprobó hipertrigliceridemia solo en 4 pacientes (7,6 %. Veintiuno de los 30 niños dislipidémicos (70 % tenían microalbuminuria. Se encontró que los pacientes con dislipidemia tenían mayor porcentaje de microalbuminuria, pero éste no fue significativo. En todos los pacientes con dislipidemia se observó una disminución del colesterol de lipoproteínas de alta densidad. La dislipidemia tuvo correlación positiva con la duración de la diabetes, pero no con el sexo. CONCLUSIONES. En la diabetes mellitus de tipo 1, el colesterol total y los triglicéridos no ofrecen información suficiente y es necesario realizar estudios del colesterol de lipoproteínas de alta densidad para poder pronosticar una futura lesión renal.

    An increased urinary albumin excretion (UAE) is associated with an augmented risk of cardiovascular disease in diabetic patients and in non-diabetic subjects. Left ventricular hypertrophy has been demonstrated to be a powerful predictor of cardiovascular morbidity and mortality in arterial hypertension and when the ventricular geometry is concentric the relation is even stronger. This echocardiographic and Doppler study was designed to evaluate the influence of microalbuminuria on the left ventricular geometry and function in hypertensive patients with type 2 diabetes melitus. Forty-two patients (16 males, 26 females, mean age 59.6 +/- 6.7 years) with mild-to-moderate essential hypertension and type 2 diabetes mellitus were enrolled in the study. Twenty-one patients had an elevated UAE (group 1) and 21 a normal UAE (group 2). M-mode (under two-dimensional control) and Doppler echocardiography were performed after a 4-week washout period off antihypertensive therapy. The left ventricular mass index was found to be greater than the partition value of 51 g/m2.7 in both groups but was significantly higher (p diabetes mellitus, an elevated UAE is associated with an increased left ventricular mass index, a higher prevalence of a concentric left ventricular hypertrophy pattern, a depressed midwall systolic performance and a markedly impaired diastolic function...

    Full Text Available Obesity is an increasing problem that more and more often affects children, thus not only the adult population. The aim of this thesis is to compare various elements and life habits of obese children with elements and habits of children practising athletics. These processes are physical activity, healthstate, eating habits, physical condition, breast-feeding period duration and the BMI of the children's parents. We have come upon an agreement with other authors that while comparing the BMI results of the parents, the two sets differed significantly. It was clearly indicated that obese children also have overweight or obese parents. Therefore it can be said that obesity is usually a problem of the whole actual family and its life-style. Regarding birth-weight, breast-feeding period duration, participation in P.E. class or a time spent watching TV or playing a computer, no major differences were noted. However, slight differences in favour to the athletes were seen in their good eating habits, their body-posture and their interest in sports in general. Here, the intensity with which active children practise sports and the time they devote to it are much higher and bigger than the energy and time spent on sports by obese children.

    Urinary albumin excretion is a useful marker in the prognosis of diabetic nephropathy and microvascular diseases. Methods such as enzyme linked immunosorbent assay (ELISA), radio immunoassay(RIA), radial immunodiffusion, albu screen, micro bumin and micral test are usually used for detection and screening of microalbuminuria in these patients. With consideration to the cost of an assay, methods such as ELISA and RIA are not suitable methods for screening purpose. Therefore, the aim of this work is to set a dot immunoblotting method for the measurement and screening of microalbumin in urine samples. The study was conducted during the period August 2001 to June 2003 at the National Research Center for Genetic Engineering and Biotechnology (NRCGEB) and Pars Hospital Laboratory of Tehran, Iran on 96 diabetic patients urine samples. First, anti human albumin antibodies (Abs) were produced in rabbit and immunoglobulin G (IgG) fraction was purified by protein-A affinity chromatography. Titer of Abs and optimum incubation conditions were tested by direct ELISA. Then different concentration of human albumin (0-300 mg/l) was loaded to nitrocellulose membranes and was assayed by dot immunoblotting method. The specificity and cross reactivity of Abs was tested by SDS-PAGE electrophoresis and western immunoblotting. The sensitivity of the method was calculated from human albumin calibration curve and compared with commercial immunoturbidimetric assays. Our results indicates that in using IgG with the concentrations 0.5-1 ug/ml (2 x 10-5 to 10-4 dilutions) the intensity of color directly increased with the increase of human albumin standards in blots. Western immunoblotting of urine samples did not show any cross reactivity with other urine proteins. Comparison of results of this method by commercial immunoturbidimetric methods indicates the correlation regression of approximately 0.979. The sensitivity of the method was approximately 5 mg/L of human albumin. This simple

    Full Text Available Abstract Background Patients in neurologic in-patient rehabilitation are at risk of cardio- and cerebrovascular events. Microalbuminuria (MAU is frequent and an important risk predictor but has not been validated in in-patient rehabilitation. We therefore aimed to examine MAU as an indicator of risk and predictor of vascular events in a prospective study. Methods The INSIGHT (INvestigation of patients with ischemic Stroke In neuroloGic reHabiliTation registry is the first to provide large scale data on 1,167 patients with acute stroke (χ2 or Mann–Whitney-U Test. Relative risks (RR with 95% confidence intervals (CI were estimated using log-binominal models. To evaluate the association between MAU and new vascular events as well as mortality, we calculated hazard ratios (HR using Cox proportional hazard regression. Results A substantial proportion of patients was MAU positive at baseline (33.1%. Upon univariate analysis these patients were about 4 years older (69 vs. 65 years; p 2; p = 0.03 and increased waist circumference (79.5 vs. 50.4% for women [p  Conclusions INSIGHT demonstrated a significant association between MAU and polyvascular disease and further supports previous findings that MAU predicts cardio-/cerebrovascular events in patients recovering from ischemic stroke. This biomarker may also be used in patients during neurologic in-patient rehabilitation, opening a window of opportunity for early intervention in this patient group at increased risk for recurrent events.

    Full Text Available Microalbuminuria is associated with hypertension and is a strong risk factor for subsequent chronic disease, both renal and coronary heart disease (CHD, Presently there are several methods available for measurement of microalbuminuria. The aim of this study was to evaluate if the three different methods gave similar information or if one of the assays were superior to the others. Blood pressure, inflammatory markers and cardiovascular mortality and morbidity were correlated with urine albumin analysed with a point-of-care testing (POCT instrument, nephelometric determination of albumin and albumin/creatinine ratio in elderly males. The study population consisted of 103 diabetic and 603 nondiabetic males (age 77 years in a cross-sectional study. We analyzed urine albumin with a HemoCue® Urine Albumin POCT instrument and a ProSpec® nephelometer and albumin/creatinine ratio. There were strong correlations between both systolic and diastolic blood pressure and all three urine albumin methods (p < 0.0001. There were also significant correlations between the different urine albumin measurements and serum amyloid A component, high-sensitivity C-reactive protein and interleukin-6. The three different urine albumin methods studied provided similar information in relation to cardiovascular disease. There was a strong correlation between systolic and diastolic blood pressure and microalbuminuria in both the whole study population and in nondiabetic males emphasizing the role of hypertension in glomerular damage. The good correlation between the studied urine albumin measurements show that all three methods can be used for monitoring urine albumin excretion.

    Full Text Available Aims Microalbuminuria (MA is a strong predictor of diabetic nephropathy and cardiovascular morbidity and mortality in patients with type-2 DM. The present study aimed to gather information on the prevalence and risk factors for MA in Indonesian patients with type-2 DM.Methods The DEMAND study was an international open cross-sectional 1-day survey on microalbuminuria prevalence and its risk factors in type-2 diabetic patients. This study reports the results of the Indonesian survey which was performed in primary care practice in Indonesia from June to December 2003. Normotensive or hypertensive adult patients of both genders with type-2 DM without known proteinuria and/or kidney disease were recruited into the study. Patients with known pregnancy, having menstruation or acute fever were excluded. A single urinary albumin/creatinine test was carried out in all patients.Results A total of 770 patients were eligible for analysis. Approximately 80% of the patients had micro-/ macroalbuminuria, while renal insufficiency was detected in about 36% of the 433 patients with available data. Target HbA1c (< 7% was reached by only 40% of the 118 patients who had HbA1c values. Most antidiabetic treatment prescribed was oral (82%, while insulin was used by only 14% of patients. Goal BP (< 130/80 mm Hg was achieved in only 9% of patients. The frequency of patients receiving antihypertensives was 52%, statins 18%, and aspirin 26%. The most frequently used antihypertensives were RAS blockers (45%, while diuretics were used in 7 % of the patients. The family history of DM was found in 43% of patients, the history of retinopathy in 16%, diabetic foot 9%, and history of smoking in 20% of patients.Conclusion These data reveal that Indonesia has one of the highest frequencies of silent diabetic kidney disease seen in any national group in the global DEMAND Study.

    We assessed whether an attachment-based treatment, Group Psychodynamic Interpersonal Psychotherapy (GPIP) had a greater impact compared to Group Cognitive Behavioral Therapy (GCBT) on Cold/Distant and Intrusive/Needy interpersonal problems. Ninety-five individuals with Binge Eating Disorder (BED) were randomized to GPIP or GCBT and assessed at pre-, post-, and six months post-treatment. Both therapies resulted in a significant decrease in all eight interpersonal problem subscales except the Nonassertive subscale. GPIP resulted in a greater reduction in the Cold/Distant subscale compared to GCBT, but no differences were found for changes in the Intrusive/Needy subscale. GPIP may be most relevant for those with BED who have Cold/Distant interpersonal problems and attachment avoidance.

    The objective was to assess the temporal impact of factors related to the development of microalbuminuria during the follow-up of young adult normoalbuminurics with high-normal blood pressure or at stage 1 of essential hypertension. Prospective follow-up was conducted on 245 normoalbuminuric hypertensive subjects (mean age 40.9 years; 134 men; blood pressure 139.7/88.6 mm Hg; body mass index 28.5 kg/m2) never treated previously with antihypertensive drugs, with yearly urinary albumin excretion measurements, until the development of microalbuminuria. After enrollment, patients were placed on usual care including nonpharmacological treatment or with an antihypertensive drug regime to achieve a blood pressure of 15 mg per 24-hour systolic blood pressure >139 mm Hg and a positive trend in fasting glucose were observed in the univariate analyses. However, in the multivariate analysis, only the baseline urinary albumin excretion and the trend of fasting glucose were independently related to the risk of developing microalbuminuria. In mild hypertensives, the development of microalbuminuria was linked to insufficient blood pressure control and to a progressive increment of glucose values.

    Spiritual interventions are rarely used in contemporary treatment programs and little empirical evidence is available concerning their effectiveness. The purpose of the present study was to evaluate the effectiveness of a spiritual group intervention for eating disorder inpatients. We compared the effectiveness of a Spirituality group with Cognitive and Emotional Support groups using a randomized, control group design. Participants were 122 women receiving inpatient eating disorder treatment. Patients in the Spirituality group tended to score significantly lower on psychological disturbance and eating disorder symptoms at the conclusion of treatment compared to patients in the other groups, and higher on spiritual well-being. On weekly outcome measures, patients in the Spirituality group improved significantly more quickly during the first four weeks of treatment. This study provides preliminary evidence that attending to eating disorder patients' spiritual growth and well-being during inpatient treatment may help reduce depression and anxiety, relationship distress, social role conflict, and eating disorder symptoms.

    Members of the genus Streptococcus within the phylum Firmicutes are among the most diverse and significant zoonotic pathogens. This genus has gone through considerable taxonomic revision due to increasing improvements of chemotaxonomic approaches, DNA hybridization and 16S rRNA gene sequencing. It is proposed to place the majority of streptococci into “species groups”. However, the evolutionary implications of species groups are not clear presently. We use comparative genomic approaches to yield a better understanding of the evolution of Streptococcus through genome dynamics, population structure, phylogenies and virulence factor distribution of species groups. Genome dynamics analyses indicate that the pan-genome size increases with the addition of newly sequenced strains, while the core genome size decreases with sequential addition at the genus level and species group level. Population structure analysis reveals two distinct lineages, one including Pyogenic, Bovis, Mutans and Salivarius groups, and the other including Mitis, Anginosus and Unknown groups. Phylogenetic dendrograms show that species within the same species group cluster together, and infer two main clades in accordance with population structure analysis. Distribution of streptococcal virulence factors has no obvious patterns among the species groups; however, the evolution of some common virulence factors is congruous with the evolution of species groups, according to phylogenetic inference. We suggest that the proposed streptococcal species groups are reasonable from the viewpoints of comparative genomics; evolution of the genus is congruent with the individual evolutionary trajectories of different species groups.

Methods: Plasma ET-1 (with RIA) serum TGF-β 1 (with ELISA)microalbuminuria (with immune method) levels were determination in 40 cases of DM2 without nephropathy, 32 cases of DM2 with nephropathy and 35 controls. Results: The plasma ET-1, serum TGF-β 1 , microalbuminuria levels in diabetic patients with nephropathy were significantly higher than those in controls(P 0.05). Conclusion: Plasma ET-1 and serum TGF-β 1 , microalbuminuria levels increased gradually as the diabetic nephropathy got more severe. They could be used as sensitive markers for early diagnosis of development of diabetic nephropathy. (authors)

    Albuminuria excretion rate above the reference range and below albustix positive proteinuria (20-199 microg/min) is known as microalbuminuria and has been associated with an increased risk of death and progression to renal failure. Besides hyperglicemia and high blood pressure levels, dietary factors can also influence albuminuria. To evaluate possible associations of dietary components (macronutrients and selected foods) with microalbuminuria in type 2 diabetic patients. In this cross-sectional study, 119 normoalbuminuric [NORMO; 24-h urinary albumin excretion (UAE) protein (20.5 +/- 4.4 vs. 19.0 +/- 3.5% of total energy; p = 0.01) with a higher intake from animal sources (14.5 +/- 4.7 vs. 12.9 +/- 3.8% of total energy; p = 0.015) than NORMO patients. The intakes of PUFAs (8.6 +/- 2.9 vs. 9.7 +/- 3.3% of total energy; p vegetable sources (7.3 +/- 3.4 vs. 8.6 +/- 3.7% of total energy; p = 0.029), plant oils [0.2 (0.1-0.6) vs. 0.3 (0.1-0.9) mg/kg weight; p = 0.02] and margarines [3.3 (0-75.7) vs. 7.0 (0-51.7) g/day; p = 0.01] were lower in MICRO than in NORMO. In multivariate logistic regression models, adjusted for age, gender, presence of hypertension and fasting plasma glucose, intake of total protein (% of total energy; OR 1.104; 95% CI 1.008-1.208; p = 0.032) was positively associated with microalbuminuria. The intakes of total PUFAs (% of total energy; OR 0.855; 95%CI 0.762-0.961; p = 0.008), PUFAs from vegetable sources (% of total energy; OR 0.874; 95%CI 0.787-0.971; p = 0.012) and plant oils (mg/kg weight; OR 0.036; 95% CI 0.003-0.522; p = 0.015) were negatively associated with microalbuminuria. In type 2 diabetic patients, the high intake of protein and the low intake of PUFAs, particularly from plant oils, were associated with the presence of microalbuminuria. Reducing protein intake from animal sources and increasing the intake of lipids from vegetable origin might-reduce the risk of microalbuminuria.

    Full Text Available Blood grouping is a vital test in pre-transfusion testing. Both tube and gel agglutination assays are used for ABO grouping. The main object of this study was to compare ABO grouping and D typing on tube and gel agglutination assay in order to assess the efficacy of each technique. A total of 100 healthy blood donors irrespective of age and sex were included in this study. Results showed that there is no significant difference between these two techniques. However, in 10 samples it was detected that the reaction strength in serum ABO grouping by gel agglutination assay is varied by only one grade when compared to tube agglutination assay. Due to numerous positive effects of gel assay it is more beneficial to implement this technique in the setups where blood banks bear heavy routine work load.

    Full Text Available The main objectives of this research were to compare the attitudes of learners between applying SDLC model with collaborative learning and typical SDLC model and to develop electronic courseware as group projects. The research was a quasi-experimental research. The populations of the research were students who took Computer Organization and Architecture course in the academic year 2015. There were 38 students who participated to the research. The participants were divided voluntary into two groups including an experimental group with 28 students using SDLC model with collaborative learning and a control group with 10 students using typical SDLC model. The research instruments were attitude questionnaire, semi-structured interview and self-assessment questionnaire. The collected data was analysed by arithmetic mean, standard deviation, and independent sample t-test. The results of the questionnaire revealed that the attitudes of the learners using collaborative learning and SDLC model were statistically significant difference between the mean score for experimental group and control group at a significance level of 0.05. The independent statistical analyses were significantly different between the two groups at a significance level of 0.05. The results of the interviewing revealed that most of the learners had the corresponding opinions that collaborative learning was very useful with highest level of their attitudes comparing with the previous methodology. Learners had left some feedbacks that collaborative learning should be applied to other courses.

    The purpose of this cross-sectional study was to compare the prevalence of low back pain (LBP) among female elite football and handball players to a matched non-professional active control group. The participants were requested to answer a questionnaire based on standardized Nordic questionnaires for musculoskeletal symptoms to assess the prevalence of LBP. Included participants were elite female football (n = 277) and handball players (n = 190), and a randomly selected control group from the Norwegian population (n = 167). Fifty-seven percentage of the football players, 59 % of the handball players and 60 % of the control group had experienced LBP the previous year. There were no significant group differences in the prevalence of LBP ever (p = 0.62), the previous year (p = 0.85) or the previous 7 days (p = 0.63). For both sports, there was a significant increase in prevalence of LBP from the resting period to the competitive periods of the season (p ≤ 0.001). Seventy percent of the goalkeepers in both football and handball had experienced LBP the previous year. There were no difference in LBP among female elite football and handball players compared with the control group. However, female elite athletes in football and handball reported a high prevalence of LBP compared to previous studies. The variations in LBP and playing positions indicate that specific field positions, in football and handball, is a risk factor for developing LBP.

    Full Text Available AIM: To determine the frequency of dry eye in computer users and to compare them with control group. METHODS: This study was a case control research conducted in 2015 in the city of Birjand. Sample size of study was estimated to be 304 subjects(152 subjects in each group, computer user group and control group. Non-randomized method of sampling was used in both groups. Schirmer test was used to evaluate dry eye of subjects. Then, subjects completed questionnaire. This questionnaire was developed based on objectives and reviewing the literature. After collecting the data, they were entered to SPSS Software and they were analyzed using Chi-square test or Fisher's test at the alpha level of 0.05.RESULTS: In total, 304 subjects(152 subjects in each groupwere included in the study. Frequency of dry eyes in the control group was 3.3%(5 subjectsand it was 61.8% in computer users group(94 subjects. Significant difference was observed between two groups in this regard(Pn=12, and it was 34.2% in computer users group(n=52, which significant difference was observed between two groups in this regard(PP=0.8. The mean working hour with computer per day in patients with dry eye was 6.65±3.52h, while it was 1.62±2.54h in healthy group(T=13.25, PCONCLUSION: This study showed a significant relationship between using computer and dry eye and ocular symptoms. Thus, it is necessary that officials need to pay particular attention to working hours with computer by employees. They should also develop appropriate plans to divide the working hours with computer among computer users. However, due to various confounding factors, it is recommended that these factors to be controlled in future studies.

    2015-04-01

    To investigate whether using a parametric statistic in comparing groups leads to different conclusions when using summative scores from rating scales compared with using their corresponding Rasch-based measures. A Monte Carlo simulation study was designed to examine between-group differences in the change scores derived from summative scores from rating scales, and those derived from their corresponding Rasch-based measures, using 1-way analysis of variance. The degree of inconsistency between the 2 scoring approaches (i.e. summative and Rasch-based) was examined, using varying sample sizes, scale difficulties and person ability conditions. This simulation study revealed scaling artefacts that could arise from using summative scores rather than Rasch-based measures for determining the changes between groups. The group differences in the change scores were statistically significant for summative scores under all test conditions and sample size scenarios. However, none of the group differences in the change scores were significant when using the corresponding Rasch-based measures. This study raises questions about the validity of the inference on group differences of summative score changes in parametric analyses. Moreover, it provides a rationale for the use of Rasch-based measures, which can allow valid parametric analyses of rating scale data.

    In a previous study we demonstrated children with Benign Rolandic Epilepsy have normal intelligence and language ability. However, difficulties in verbal and visual memory and aspects of phonological awareness were found compared to normative data. To address the methodological limitations related to the use of normative data, we compared the same cohort of children with Benign Rolandic Epilepsy to a matched control group. Controls (n=40) matched on age and gender to the Benign Rolandic Epilepsy cohort underwent neuropsychological assessment. The life functioning of the control group was assessed using a modified version of the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE). The study confirmed the previous findings of memory and phonological awareness difficulties. In addition, the children with Benign Rolandic Epilepsy had significantly lower IQ scores than the matched control group. Paired sample t-tests showed that on 8 of 11 QOLCE scales, children with Benign Rolandic Epilepsy were rated by parents as having poorer life functioning compared to matched controls, including lower parental ratings on the subscales of memory and language. Benign Rolandic Epilepsy has an excellent seizure prognosis, but this study further emphasizes potential cognitive difficulties. Using an age and gender matched control group, the previous findings of memory and phonological awareness difficulties were validated. These problems in cognition were also identified by parents of children with Benign Rolandic Epilepsy as problematic and impacting upon the child's quality of life.

    2015-01-01

    Little is known about the varying patterns of member engagement within inflammatory bowel disease online support groups. The aim of the study was, therefore, to compare posters and lurkers (i.e., those who read messages but choose not to post) in terms of engagement and motives for accessing online groups as well as to explore reasons why lurkers do not make an active contribution through posting messages. The findings revealed that those who posted messages visited groups more often and spent longer periods of time accessing them. However, there was no difference between posters and lurkers in terms of length of time as a group member. Furthermore, posters were more inclined to access online support groups to both seek and provide emotional, informational, and experiential support. Finally, four main reasons were described by lurkers for not posting messages and these focused on personal factors, illness severity, being helpful, and new member. For those healthcare professionals or patient volunteers who are involved in supporting inflammatory bowel disease online support groups, there are a number of practical strategies arising from these results which can be implemented to help integrate and encourage active participation by all members.

    Identifying the genetic variability in vertically transmitted viruses in early infancy is important to understand the disease progression. Being important in HIV-1 disease pathogenesis, vpu gene, isolated from young infants was investigated to understand the viral characteristics. Blood samples were obtained from 80 HIV-1 positive infants, categorized in two age groups; acute (6-18 months). A total of 77 PCR positive samples, amplified for vpu gene, were sequenced and analyzed. 73 isolates belonged to subtype C. Analysis of heterogeneity of amino acid sequences in infant groups showed that in the sequences of acute age group both insertions and deletions were present while in the early age group only deletions were present. In the acute age group, a deletion of 3 residues (RAE) in the first alfa helix in one sequence and insertions of 1-2 residues (DM, GH, G and H) in the second alfa helix in 4 sequences were observed. In the early age group, deletion of 2 residues (VN) in the cytoplasmic tail region in 2 sequences was observed. Length of the amino terminal was observed to be gradually increasing with the increasing age of the infants. Protein Variation Effect Analyzer software showed that deleterious mutations were more in the acute than the early age group. Entropy analysis revealed that heterogeneity of the residues was comparatively higher in the sequences of acute than the early age group. Mutations observed in the helixes may affect the conformation and lose the ability to degrade CD4 receptors. Heterogeneity was decreasing with the increasing ages of the infants, indicating positive selection for robust virion survival.

  8. Ethnicity and child health in northern Tanzania: Maasai pastoralists are disadvantaged compared to neighbouring ethnic groups.

    Directory of Open Access Journals (Sweden)

    David W Lawson

    Full Text Available The Maasai of northern Tanzania, a semi-nomadic ethnic group predominantly reliant on pastoralism, face a number of challenges anticipated to have negative impacts on child health, including marginalisation, vulnerabilities to drought, substandard service provision and on-going land grabbing conflicts. Yet, stemming from a lack of appropriate national survey data, no large-scale comparative study of Maasai child health has been conducted. Savannas Forever Tanzania surveyed the health of over 3500 children from 56 villages in northern Tanzania between 2009 and 2011. The major ethnic groups sampled were the Maasai, Sukuma, Rangi, and the Meru. Using multilevel regression we compare each ethnic group on the basis of (i measurements of child health, including anthropometric indicators of nutritional status and self-reported incidence of disease; and (ii important proximate determinants of child health, including food insecurity, diet, breastfeeding behaviour and vaccination coverage. We then (iii contrast households among the Maasai by the extent to which subsistence is reliant on livestock herding. Measures of both child nutritional status and disease confirm that the Maasai are substantially disadvantaged compared to neighbouring ethnic groups, Meru are relatively advantaged, and Rangi and Sukuma intermediate in most comparisons. However, Maasai children were less likely to report malaria and worm infections. Food insecurity was high throughout the study site, but particularly severe for the Maasai, and reflected in lower dietary intake of carbohydrate-rich staple foods, and fruits and vegetables. Breastfeeding was extended in the Maasai, despite higher reported consumption of cow's milk, a potential weaning food. Vaccination coverage was lowest in Maasai and Sukuma. Maasai who rely primarily on livestock herding showed signs of further disadvantage compared to Maasai relying primarily on agriculture. We discuss the potential ecological

    Full Text Available BACKGROUND: Studies of racial/ethnic variations in stroke rarely consider the South Asian population, one of the fastest growing sub-groups in the United States. This study compared risk factors for stroke among South Asians with those for whites, African-Americans, and Hispanics. METHODS: Data on 3290 stroke patients were analyzed to examine risk differences among the four racial/ethnic groups. Data on 3290 patients admitted to a regional stroke center were analyzed to examine risk differences for ischemic stroke (including subtypes of small and large vessel disease among South Asians, whites, African Americans and Hispanics. RESULTS: South Asians were younger and had higher rates of diabetes mellitus, blood pressure, and fasting blood glucose levels than other race/ethnicities. Prevalence of diabetic and antiplatelet medication use, as well as the incidence of small-artery occlusion ischemic stroke was also higher among South Asians. South Asians were almost a decade younger and had comparable socioeconomic levels as whites; however, their stroke risk factors were comparable to that of African Americans and Hispanics. DISCUSSION: Observed differences in stroke may be explained by dietary and life style choices of South Asian-Americans, risk factors that are potentially modifiable. Future population and epidemiologic studies should consider growing ethnic minority groups in the examination of the nature, outcome, and medical care profiles of stroke.

  14. Comparing group deliberation to other forms of preference aggregation in valuing ecosystem services

    2017-12-01

    Full Text Available Deliberative methods for valuing ecosystem services are hypothesized to yield group preferences that differ systematically from those that would be obtained through calculative aggregation of the preferences of participating individuals. We tested this hypothesis by comparing the group consensus results of structured deliberations against a variety of aggregation methods applied to individual participant preferences that were elicited both before and after the deliberations. Participants were also asked about their perceptions of the deliberative process, which we used to assess their ability to detect preference changes and identify the causes of any changes. For five of the seven groups tested, the group consensus results could not have been predicted from individual predeliberation preferences using any of the aggregation rules. However, individual postdeliberation preferences could be used to reconstruct the group preferences using consensual and rank-based aggregation rules. These results imply that the preferences of participants changed over the course of the deliberation and that the group preferences reflected a broad consensus on overall rankings rather than simply the pairwise preferences of the majority. Changes in individual preferences seem to have gone largely unnoticed by participants, as most stated that they did not believe their preferences had substantially changed. Most participants were satisfied with the outcome of the deliberation, and their degree of satisfaction was correlated with the feeling that their opinion was heard and that they had an influence on the outcome. Based on our results, group deliberation shows promise as a means of generating ecosystem service valuations that reflect a consensus opinion rather than simply a collection of personal preferences.

    The present study is an attempt to explore the association between kitchen indoor air pollutants and physiological profiles in kitchen workers with microalbuminuria (MAU) in north India (Lucknow) and south India (Coimbatore). The subjects comprised 145 control subjects, 233 kitchen workers from north India and 186 kitchen workers from south India. Information related to the personal and occupational history and health of the subjects at both locations were collected using a custom-made questionnaire. Worker lung function was measured using a spirometer. Blood pressure was monitored using a sphygmomanometer. Urinary MAU was measured using a urine analyzer. Indoor air monitoring in kitchens for particulate matter (PM), total volatile organic compounds (TVOC), carbon dioxide (CO 2 ) and carbon monoxide (CO) was conducted using indoor air quality monitors. The size and shape of PM in indoor air was assessed using a scanning electron microscope (SEM). Fourier transform infrared (FTIR) spectroscopy was used to detect organic or inorganic compounds in the air samples. Particulate matter concentrations (PM 2.5 and PM 1 ) were significantly higher in both north and south Indian kitchens than in non-kitchen areas. The concentrations of TVOC, CO and CO 2 were higher in the kitchens of north and south India than in the control locations (non-kitchen areas). Coarse, fine and ultrafine particles and several elements were also detected in kitchens in both locations by SEM and elemental analysis. The FTIR spectra of kitchen indoor air at both locations show the presence of organic chemicals. Significant declines in systolic blood pressure and lung function were observed in the kitchen workers with MAU at both locations compared to those of the control subjects. A higher prevalence of obstruction cases with MAU was observed among the workers in the southern region than in the controls (p workers in south India have lower lung capacities and a greater risk of obstructive and

    Biogeographic patterns of the three main Nearctic groups of continental fishes inhabiting river drainages in central Mexico (livebearing goodeids, southern Mexican notropins and species of Algansea, the last two representing independent lineages of cyprinids) were obtained and compared by following two approaches: an estimate of divergence times and using a well-defined biogeographic method. Three concordant biogeographic events were identified among the three groups, showing some evidence of a partially congruent evolutionary history. The analysed groups show at least three independent colonization events into central Mexico: two western routes, followed by the Goodeinae and members of Algansea, and an early Plateau route followed by southern notropins. The most recent common ancestor (MRCA) of each of the three freshwater fish groups diversified in central Mexico in the Late Miocene. The lack of a strong congruence in their biogeographic patterns, and the differences in species richness among the three clades might be evidence for distinct patterns of diversification. © 2015 The Fisheries Society of the British Isles.

    Genome features of the Bacillus cereus group genomes (representative strains of Bacillus cereus, Bacillus anthracis and Bacillus thuringiensis sub spp israelensis) were analyzed and compared with the Bacillus subtilis genome. A core set of 1,381 protein families among the four Bacillus genomes, with an additional set of 933 families common to the B. cereus group, was identified. Differences in signal transduction pathways, membrane transporters, cell surface structures, cell wall, and S-layer proteins suggesting differences in their phenotype were identified. The B. cereus group has signal transduction systems including a tyrosine kinase related to two-component system histidine kinases from B. subtilis. A model for regulation of the stress responsive sigma factor sigmaB in the B. cereus group different from the well studied regulation in B. subtilis has been proposed. Despite a high degree of chromosomal synteny among these genomes, significant differences in cell wall and spore coat proteins that contribute to the survival and adaptation in specific hosts has been identified.

  18. Phage morphology recapitulates phylogeny: the comparative genomics of a new group of myoviruses.

    Directory of Open Access Journals (Sweden)

    André M Comeau

    Full Text Available Among dsDNA tailed bacteriophages (Caudovirales, members of the Myoviridae family have the most sophisticated virion design that includes a complex contractile tail structure. The Myoviridae generally have larger genomes than the other phage families. Relatively few "dwarf" myoviruses, those with a genome size of less than 50 kb such as those of the Mu group, have been analyzed in extenso. Here we report on the genome sequencing and morphological characterization of a new group of such phages that infect a diverse range of Proteobacteria, namely Aeromonas salmonicida phage 56, Vibrio cholerae phages 138 and CP-T1, Bdellovibrio phage φ1422, and Pectobacterium carotovorum phage ZF40. This group of dwarf myoviruses shares an identical virion morphology, characterized by usually short contractile tails, and have genome sizes of approximately 45 kb. Although their genome sequences are variable in their lysogeny, replication, and host adaption modules, presumably reflecting differing lifestyles and hosts, their structural and morphogenesis modules have been evolutionarily constrained by their virion morphology. Comparative genomic analysis reveals that these phages, along with related prophage genomes, form a new coherent group within the Myoviridae. The results presented in this communication support the hypothesis that the diversity of phages may be more structured than generally believed and that the innumerable phages in the biosphere all belong to discrete lineages or families.

    The study aimed to test whether working memory deficits in children at risk of Learning Disabilities (LD) and/or attention deficit/hyperactivity disorder (ADHD) can be attributed to deficits in interference control, thereby implicating prefrontal systems. Two groups of children known for showing poor working memory (i.e., children with poor comprehension and children with ADHD) were compared to a group of children with specific reading decoding problems (i.e., having severe problems in phonological rather than working memory) and to a control group. All children were tested with a verbal working memory task. Interference control of irrelevant items was examined by a lexical decision task presented immediately after the final recall in about half the trials, selected at random. The interference control measure was therefore directly related to working memory performance. Results confirmed deficient working memory performance in poor comprehenders and children at risk of ADHD + LD. More interestingly, this working memory deficit was associated with greater activation of irrelevant information than in the control group. Poor decoders showed more efficient interference control, in contrast to poor comprehenders and ADHD + LD children. These results indicated that interfering items were still highly accessible to working memory in children who fail the working memory task. In turn, these findings strengthen and clarify the role of interference control, one of the most critical prefrontal functions, in working memory.

    The present study aimed to investigate the level of self-esteem among religious minority adolescents (Christians and Hindus) by making a comparison with their dominant counterparts (Muslims) in Pakistan. It was hypothesized that adolescents of religious minorities would have lower level of self-esteem than their dominant counterparts. In the present study 320 adolescents participated, in which 160 adolescents belonged to minority religious groups (i.e. 76 Christians and 84 Hindus) and 160 adolescents belonged to dominant religious group i.e. Muslims. To assess self-esteem of the participants, Rosenberg Self-Esteem Scale (Rosenberg in Society and the adolescent self image, Princeton University Press, Princeton, NJ, 1965) was used. One Way Analysis of Variance reveals that religious minority adolescents (Christians and Hindus) inclined to have lower self-esteem as compared to their dominant counterpart (Muslim adolescents).

    Background The population in Norway has become multi-ethnic due to migration from Asia and Africa over the recent decades. The aim of the present study was to explore differences in the self-reported prevalence of cardiovascular disease (CVD) and associated risk factors by diabetes status in five ethnic minority groups compared to ethnic Norwegians. Methods Pooled data from three population-based cross-sectional studies conducted in Oslo between 2000 and 2002 was used. Of 54,473 invited individuals 24,749 (45.4%) participated. The participants self-reported health status, underwent a clinical examination and blood samples were drawn. A total of 17,854 individuals aged 30 to 61 years born in Norway, Sri-Lanka, Pakistan, Iran, Vietnam or Turkey were included in the study. Chi-square tests, one-way ANOVAs, ANCOVAs, multiple and logistic regression were used. Results Age- and gender-standardized prevalence of self-reported CVD varied between 5.8% and 8.2% for the ethnic minority groups, compared to 2.9% among ethnic Norwegians (p Corresponding CVD prevalence rates among individuals with diabetes were 15.3% vs. 12.6% (p = 0.364). For individuals without diabetes, the odds ratio (OR) for CVD in the ethnic minority groups remained significantly higher (range 1.5-2.6) than ethnic Norwegians (p employment, and body height, except for Turkish individuals. Regardless of diabetes status, obesity and physical inactivity were prevalent in the majority of ethnic minority groups, whereas systolic- and diastolic- blood pressures were higher in Norwegians. In nearly all ethnic groups, individuals with diabetes had higher triglycerides, waist-to-hip ratio (WHR), and body mass index compared to individuals without diabetes. Age, diabetes, hypertension, hypercholesterolemia, and WHR were significant predictors of CVD in both ethnic Norwegians and ethnic minorities, but significant ethnic differences were found for age, diabetes, and hypercholesterolemia.

    One difficulty in understanding the effect of multi-scale patterns in watersheds comes from finding a concise way to identify and compare features across many basins. Comparing raw data (i.e. discharge time series) requires one to account for highly variable climate drivers while extracting meaningful metrics from the data series. Comparing model parameters imposes model assumptions that may obscure fundamental differences, potentially making it an exercise in comparing calibration factors. As a possible middle ground, we have found that the probability of a given basin-wide runoff response can be predicted by combining rainfall frequency with 1. a curve establishing a relationship between basin storage and base flow and 2. the baseflow flow-duration curve. In addition to providing a means to predict runoff, these curves succinctly present empirical runoff-response information, allowing ready graphical comparison of multiple watersheds. From 40+ watersheds throughout the Northeastern U.S., we demonstrate the potential to group watersheds and identify critical hydrologic features, providing particular insight into the influence of land use patterns as well as basin scale.

    A total of 56 Japanese and 59 American survivor of suicide support group facilitators were asked to rank the mutual aid objectives of their groups following Shulman's scheme in terms of their frequency and importance. Both American and Japanese facilitators showed an emphasis on personal adaptation goals (such as helping bereaved feel less isolated in their grief or encouraging bereaved to share their coping with loss experiences) over collective goals (such as raising monies for more research on mental illness or trying to combat societal suicide stigma in their local communities). Differences were also noted with American facilitators evaluating helping with problem solving, sharing different ways of coping, viewing personal issues as societal problems, and advocating for promoting social change as significantly higher than the Japanese did. We believe some of these contrasts reflect differences in American and Japanese cultural values.

    The alcoholics were diagnosed and classified based on the criteria, offered at the Alcoholism Diagnostic Conference (1977) which was held under the auspices of the Ministry of Welfare, Japan. Grade of cerebral atrophy was estimated. Measurement items on the Computed Tomography (CT Scan) which contributed to discrimination among these groups were investigated simultaneously. The study consisted of seventy-five alcoholic patients and control group of ninety-four who were devoid of any evidence for alcoholism. Influential factors which were involved in cerebral atrophy of the alcoholic groups were investigated and factorial analysis was completed. There was a definite increase in cerebral atrophy during the aging process in patients with long term durations of drinking alcohol. There was a close correlation between age and duration of drinking alcohol. After the results of canonical discriminant analysis against 9 CT items, the Ventricle index definitely contributed both in the discrimination between the alcoholics and the controls and in the discrimination between alcoholic dementia and other alcoholic psychoses. Furthermore, the horizontal diameter of the third ventricle contributed to the latter discrimination, while the Evans' index contributed to the former discrimination. Therefore, the Ventricle index and the Evans' index turn out as the most valuable diagnostic criteria, as well as the CT index against cerebral atrophy in the alcoholics; however, the horizontal diameter of the third ventricle is useful in comparing among alcoholic psychoses.

    Full Text Available Savings generated by the sector of households constitute an important growth factor in every economy. They are the basic source of capital accumulation, determining investment opportunities of the economy. Financial behaviour of households in terms of the accumulation of savings is infl uenced  by numerous factors, both internal, i.e. connected directly with a given household, and external, independent of it. The aim of this paper was to analyse savings behaviour of households of farmers as compared to the other socio-economicgroups in Poland in the years 2003 and 2013. Analyses were conducted on saving propensity, savings rates, and objectives and forms of savings accumulation by households of various socio-economic groups. Analyses showed that in 2013, saving propensity and savings rates in households of farmers were relatively low in comparison to other household groups. In households of farmers the objective of savings was, more frequently than in the other socio-economic groups of households, to ensure provisions for running consumption expenditure, purchase durable goods and expand their economic activity. In contrast, in comparison to the other households, farmers less frequently saved money for recreation and physical therapy.

    Full Text Available Introduction & Objective: Diabetes mellitus is one of the most common chronic diseases in western developed countries and developing countries, whose prevalence is increasing worldwide. One of the vascular complications of diabetes is diabetic retinopathy. Given the prevalence of diabetic retinopathy and its complications in patients with type 2 diabetes, the aim of this study was to investigate the prevalence of retinopathy in diabetic patients and to determine the relationship between microalbuminuria and retinopathy in patients with type 2 diabetes in Hamadan. Materials & Methods: This study was a cross-sectional study in which 284 medical records of patients referred to the Diabetes Center of Hamadan were studied whose eye examinations were recorded and their laboratory tests have been measured at a laboratory center. Then, the data obtained from the average of experiments during the last year and examinations carried out were entered in the check list and the statistical results of the data were analyzed and the relationship between microalbuminuria and retinopathy was evaluated. Results: In our study, 284 patients were studied. 154 (54.22% of the patients in our study had retinopathy. In persons who had retinopathy, 36.36% of patients were with mild NPDR, 27.92% with moderate NPDR, 7.79% with severe NPDR and 27.92% had PDR. In our study, 32.04% of patients had microalbuminuria, and of these, 80.21% also had retinopathy. There was a significant relationship between retinopathy and microalbuminuria. Conclusions: The results of this study showed that the prevalence of retinopathy in our study is about 54 percent, which is relatively a higher prevalence than that in other similar studies. Also, due to the strong correlation between the presence of microalbuminuria and retinopathy and also duration of diabetes, a closer look at diabetic patients for microalbuminuria in periodic eye examinations is recommended.

    A comparative study was conducted on the 20 knees of 10 females with normal knee joints (age, 22-35 years) and on 7 knees of 7 patients with subluxation syndrome (age, 15-24 years), using axial radiography and CT. In axial radiography where the angle of knee flexion was 30 deg or 60 deg, no significant difference was recognized between the two groups with respect to tilting angle, patellofemoral angle, congruence angle and lateral shift. However, a significant difference was found using CT. Thus, CT was considered useful for diagnosis. Because of these results, all 7 cases underwent surgery for detachment of the lateral side and tightening of the medial side. Three cases underwent shifting of the tibial tuberosity to the anteromedial side, resulting in a favourable outcome. Here, we report the study. (author).

    There is an increasing awareness of the advantages of multi-modal neuroimaging. Networks obtained from different modalities are usually treated in isolation, which is however contradictory to accumulating evidence that these networks show non-trivial interdependencies. Even networks obtained from a single modality, such as frequency-band specific functional networks measured from magnetoencephalography (MEG) are often treated independently. Here, we discuss how a multilayer network framework allows for integration of multiple networks into a single network description and how graph metrics can be applied to quantify multilayer network organisation for group comparison. We analyse how well-known biases for single layer networks, such as effects of group differences in link density and/or average connectivity, influence multilayer networks, and we compare four schemes that aim to correct for such biases: the minimum spanning tree (MST), effective graph resistance cost minimisation, efficiency cost optimisation (ECO) and a normalisation scheme based on singular value decomposition (SVD). These schemes can be applied to the layers independently or to the multilayer network as a whole. For correction applied to whole multilayer networks, only the SVD showed sufficient bias correction. For correction applied to individual layers, three schemes (ECO, MST, SVD) could correct for biases. By using generative models as well as empirical MEG and functional magnetic resonance imaging (fMRI) data, we further demonstrated that all schemes were sensitive to identify network topology when the original networks were perturbed. In conclusion, uncorrected multilayer network analysis leads to biases. These biases may differ between centres and studies and could consequently lead to unreproducible results in a similar manner as for single layer networks. We therefore recommend using correction schemes prior to multilayer network analysis for group comparisons. Copyright © 2017 Elsevier

    The aim was to investigate structural empowerment in nurse leaders in middle management positions. Objectives were to determine levels of empowerment of nurse leaders and to compare levels of empowerment between nurse leader groups. Access to formal and informal power, opportunity, resources, information and support are determinants of structural empowerment. Empowerment of nurse leaders in middle management positions is vital given their roles in enabling nursing teams to deliver high-quality care, benefitting both patient and workforce outcomes. Quantitative component of a mixed methods study using survey principles. The Conditions of Work Effectiveness Questionnaire II was distributed to the total population (n = 517) of nurse leaders in an NHS Foundation Trust in England. Nurse leader groups comprised unit leaders (sisters, matrons) and senior staff nurses. Quantitative data entered on spss v 17/18, were analysed using descriptive and inferential statistics. Overall, the unit response rate was 44·1% (n = 228). Levels of total and global empowerment were moderate and moderate to high respectively. Groups did not differ significantly on these parameters or on five elements of total empowerment, but significantly higher scores were found for unit leaders' access to information. Significantly higher scores were found for senior staff nurses on selected aspects of informal power and access to resources, but scores were significantly lower than unit leaders for components of support. A moderately empowered population of nurse leaders differed in relation to access to information, aspects of support, resources and informal power, reflecting differences in roles, spheres of responsibility, hierarchical position and the constraints on empowerment imposed on unit leaders by financial and resource pressures. Empowerment of nurse leaders in middle management is vital in enabling nursing teams to deliver high-quality care. Roles, spheres of responsibility, hierarchical

    Literature has shown there are significant differences between administrative databases and clinical registry data. Our objective was to compare the identification of trauma patients using All Patient Refined Diagnosis Related Groups (APR-DRG) as compared to the Trauma Registry and estimate the effects of those discrepancies on utilization. Admitted pediatric patients from 1/2012-12/2013 were abstracted from the trauma registry. The patients were linked to corresponding administrative data using the Pediatric Health Information System database at a single children's hospital. APR-DRGs referencing trauma were used to identify trauma patients. We compared variables related to utilization and diagnosis to determine the level of agreement between the two datasets. There were 1942 trauma registry patients and 980 administrative records identified with trauma-specific APR-DRG during the study period. Forty-two percent (816/1942) of registry records had an associated trauma-specific APR-DRG; 69% of registry patients requiring ICU care had trauma APR-DRGs; 73% of registry patients with head injuries had trauma APR-DRGs. Only 21% of registry patients requiring surgical management had associated trauma APR-DRGs, and 12.5% of simple fractures had associated trauma APR-DRGs. APR-DRGs appeared to only capture a fraction of the entire trauma population and it tends to be the more severely ill patients. As a result, the administrative data was not able to accurately answer hospital or operating room utilization as well as specific information on diagnosis categories regarding trauma patients. APR-DRG administrative data should not be used as the only data source for evaluating the needs of a trauma program. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Critics of emerging adulthood theory have suggested that it only applies to college students, but this assertion has largely gone untested. The purpose of the present study was to compare developmental trajectories of non-students versus college-educated youth in theoretically relevant domains of work, love, and financial independence. Using data from the Youth Development Study (N = 1139, 49.6 % female, 63.3 % White, 10.9 % Southeast Asian, 1.5 % Other Asian, 8.6 % Black, 5.3 % Mixed Race, 4.0 % Latino, 0.8 % Native American), latent growth curve models were fitted to chart each group's development, from ages 14 to 30. Different trajectories were revealed for hours worked, children, and financial dependence on parents, spouses, and government aid. No differences were found in employment rates, marriage rates, or financial dependence on own income. These results provide a clearer picture of emerging adulthood for non-students, and highlight problems with generalizing college student research to all emerging adults.

    Superficial mycoses are considered to affect more frequently patients with type 2 diabetes mellitus (DM-2), specially onychomycosis and Tinea pedis. The purpose of this study was to compare the dermatophytoses, candidiasis and Pitiriasis versicolor frequency between 40 patients with DM-2 and 40 healthy persons of either sex, 40 years old or more. Clinical, metabolic, mycologic and inmunologic studies against Candida albicans, were carried out. Both diabetics 75% (30/40) and controls 65% (26/40) presented a high frequency of superficial mycoses (no significant difference p = 0.329). Pitiriasis versicolor was not detected in diabetic patients. They presented Tinea unguium, concomitant with Tinea pedis, with a higher frequency. The predominant dermatophyte was Trichophyton rubrum 18/23 (78%) in diabetics and 8/16 (50%) in non diabetics. Candida was isolated as commensal from oral mucous: 23/40 (58%) in diabetics and 21/40 (52%) in non diabetics (serotipo A was the more frequent), and from onychomycosis: 11/40 (28%) in diabetics and 12/40 (30%) in non diabetics. The immunological response was the same in both groups: celular 100%, humoral 20%. No statistical correlation among superficial mycoses, blood glucose level, glycosylated hemoglobin values or the time suffering the disease was observed. The high susceptibility to dermatophytes and Candida sp. infection showed to be associated with age and no with the diabetic type 2 condition in those patients.

    Full Text Available 1. Average values of animal group sizes are prone to be overestimated in traditional field studies because small groups and singletons are easier to overlook than large ones. This kind of bias also applies for the method of locating groups by tracking previously radio-collared individuals in the wild. If the researcher randomly chooses a collared animal to locate a group to visit, a large group has higher probability to be selected than a small one, simply because it has more members.

    Full Text Available Purpose Vitamin D deficiency is reported to be more common in type 1 diabetes patients and might be associated with the increased urinary loss of vitamin D binding protein (VDBP consequent to impaired 25-hydroxyvitamin D (25(OHD circulation. We aimed to evaluate the possible increased urinary loss of VDBP, a correlation between VDBP and circulating 25(OHD level, and risk factors influencing low vitamin D level in pediatric type 1 diabetes patients without microalbuminuria. Methods This is a cross-sectional study of subjects who visited Seoul National University Children’s Hospital between January and March 2013. Forty-two type 1 diabetes patients and 29 healthy controls were included. Biochemical parameters including serum and urine VDBP concentrations were analyzed. Results There was no significant difference in the frequency of vitamin D deficiency or serum 25(OHD level between the 2 groups. The serum and urine VDBP concentrations did not show any difference between the 2 groups. Serum 25(OH D level did not correlate with serum or urine VDBP. Multivariate regression analysis revealed that daylight outdoor hours (β=2.948, P=0.003 and vitamin D intake (β=2.865, P=0.003 affected the 25(OHD level; the presence of type 1 diabetes or urinary VDBP excretion was not significant. Conclusions In pediatric type 1 diabetes patients, urinary VDBP excretion did not contribute to low serum 25(OHD level in the setting of normoalbuminuria. The factors associated with 25(OHD level during winter periods were daylight outdoor hours and vitamin D intake. Further studies including both micro- and macroalbuminuria patients with type 1 diabetes are warranted.

    2018-02-01

    Following the risk-need-responsivity (RNR) model, cognitive-behavioral therapy is considered most effective in reducing recidivism when based on dynamic risk factors. As studies have found differences of these factors across age, exploring this seems beneficial. The current study investigates the Central Eight (C8) risk factors across six age groups of outpatient sex offenders ( N = 650). Results showed that recidivism rates and age were inversely related from 19 years and up. Half of the C8 did not predict general recidivism at all, substance abuse, antisocial cognition, antisocial associates, and history of antisocial behavior in only one or several age groups. However, factors differed between age groups, with the youngest group demonstrating the most dysfunction in several areas and the oldest group the least. It is concluded that the C8 risk factors seem to lose significance in the older age groups. Results may benefit targeting treatment goals.

    In this study, we modelled population responses to chronic external gamma radiation in 12 laboratory species (including aquatic and soil invertebrates, fish and terrestrial mammals). Our aim was to compare radiosensitivity between individual and population endpoints and to examine how internationally proposed benchmarks for environmental radioprotection protected species against various risks at the population level. To do so, we used population matrix models, combining life history and chronic radiotoxicity data (derived from laboratory experiments and described in the literature and the FREDERICA database) to simulate changes in population endpoints (net reproductive rate R_0, asymptotic population growth rate λ, equilibrium population size N_e_q) for a range of dose rates. Elasticity analyses of models showed that population responses differed depending on the affected individual endpoint (juvenile or adult survival, delay in maturity or reduction in fecundity), the considered population endpoint (R_0, λ or N_e_q) and the life history of the studied species. Among population endpoints, net reproductive rate R_0 showed the lowest EDR_1_0 (effective dose rate inducing 10% effect) in all species, with values ranging from 26 μGy h"−"1 in the mouse Mus musculus to 38,000 μGy h"−"1 in the fish Oryzias latipes. For several species, EDR_1_0 for population endpoints were lower than the lowest EDR_1_0 for individual endpoints. Various population level risks, differing in severity for the population, were investigated. Population extinction (predicted when radiation effects caused population growth rate λ to decrease below 1, indicating that no population growth in the long term) was predicted for dose rates ranging from 2700 μGy h"−"1 in fish to 12,000 μGy h"−"1 in soil invertebrates. A milder risk, that population growth rate λ will be reduced by 10% of the reduction causing extinction, was predicted for dose rates ranging from 24 μGy h"−"1

    Background In diabetes one of the main features of the progression to diabetic kidney disease is a pathological deposition of extracellular matrix components triggering renal fibrosis. The main structural component of the fibrotic core is collagen. One of the most prominent collagens is collagen...... type III (COL III), which is excessively synthesized and incorporated into the fibrotic extracellular matrix. Multiple studies in both humans and mice have suggested that MMP-9 activity is increased in diabetic kidney disease. We investigated whether a neo-epitope fragment of COL III generated by MMP-9......

    Full Text Available Abstract Background Safe and effective weight control strategies are needed to stem the current obesity epidemic. The objective of this one-year study was to document and compare the macronutrient and micronutrient levels in the foods chosen by women following two different weight reduction interventions. Methods Ninety-six generally healthy overweight or obese women (ages 25–50 years; BMI 25–35 kg/m2 were randomized into a Traditional Food group (TFG or a Meal Replacement Group (MRG incorporating 1–2 meal replacement drinks or bars per day. Both groups had an energy-restricted goal of 5400 kJ/day. Dietary intake data was obtained using 3-Day Food records kept by the subjects at baseline, 6 months and one-year. For more uniform comparisons between groups, each diet intervention consisted of 18 small group sessions led by the same Registered Dietitian. Results Weight loss for the 73% (n = 70 completing this one-year study was not significantly different between the groups, but was significantly different (p ≤ .05 within each group with a mean (± standard deviation weight loss of -6.1 ± 6.7 kg (TFG, n = 35 vs -5.0 ± 4.9 kg (MRG, n = 35. Both groups had macronutrient (Carbohydrate:Protein:Fat ratios that were within the ranges recommended (50:19:31, TFG vs 55:16:29, MRG. Their reported reduced energy intake was similar (5729 ± 1424 kJ, TFG vs 5993 ± 2016 kJ, MRG. There was an improved dietary intake pattern in both groups as indicated by decreased intake of saturated fat (≤ 10%, cholesterol ( Conclusion In this one-year university-based intervention, both dietitian-led groups successfully lost weight while improving overall dietary adequacy. The group incorporating fortified meal replacements tended to have a more adequate essential nutrient intake compared to the group following a more traditional food group diet. This study supports the need to incorporate fortified foods and/or dietary supplements while following an energy

This study was designed to assess and compare the effect of the goal setting strategy with a group education method on increasing the physical activity of mothers of children aged 1 to 5. Mothers who had at least one child of 1-5 years were randomized into two groups. The effect of 1) goal-setting strategy and 2) group education method on increasing physical activity was assessed and compared 1 month and 3 months after the intervention. Also, the weight, height, body mass index (BMI), waist and hip circumference, and well-being were compared between the two groups before and after the intervention. Physical activity level increased significantly after the intervention in the goal-setting group and it was significantly different between the two groups after intervention (P goal-setting group after the intervention. In the group education method, only the well-being score improved significantly (P goal-setting strategy to boost physical activity, improving the state of well-being and decreasing BMI, waist, and hip circumference.

Also, the weight, height, body mass index (BMI, waist and hip circumference, and well-being were compared between the two groups before and after the intervention. Results: Physical activity level increased significantly after the intervention in the goal-setting group and it was significantly different between the two groups after intervention (P < 0.05. BMI, waist circumference, hip circumference, and well-being score were significantly different in the goal-setting group after the intervention. In the group education method, only the well-being score improved significantly (P < 0.05. Conclusion: Our study presented the effects of using the goal-setting strategy to boost physical activity, improving the state of well-being and decreasing BMI, waist, and hip circumference.

    Features of the frontal bone that are conventionally used to distinguish among fossil hominin groups were quantitatively examined. Fifty-five fossil crania dating from the early to the late Pleistocene were analyzed. Using a modified pantograph, outlines of the frontal bone were collected along the midsagittal and two parasagittal planes. The profile from nasion to bregma, as well as two profiles above the medial and lateral sections of the orbit, respectively, extending from the orbital margin to the coronal suture were traced. The outlines were measured using Elliptical Fourier Function Analysis (EFFA), which enabled a quantification of aspects of the frontal bone that have historically been described primarily in nonmetric or linear terms. Four measurements were obtained: 1) overall morphology as expressed in the Fourier harmonic amplitudes; 2) maximum projection of the supraorbital torus at three points along the browridge (glabella and the medial and lateral aspects of the torus above the orbit); 3) maximum distance of the frontal squama from the frontal chord, capturing forehead curvature; and 4) nasion-bregma chord length. The results indicate that the midsagittal profile is significantly different among all Pleistocene groups in analyses that include both size and shape, as well as size-adjusted data. Homo erectus is significantly different from the late Pleistocene groups (Neandertals and early modern H. sapiens) in glabellar projection. Anatomically modern humans are significantly different from all other groups in both raw and size-standardized analyses of all three outlines that captured overall morphology, as well as forehead curvature and lateral supraorbital torus prominence, and middle Pleistocene Homo are significantly different in both medial and lateral overall parasagittal form. However, for the majority of analyses there were no significant differences among the Pleistocene archaic groups in supraorbital torus projection, frontal squama

    2014-01-01

    In a study of three indigenous and non-indigenous cultural groups in northwestern and northeastern Siberia, framed line tests and a landscape drawing task were used to examine the hypotheses that test-based assessments of context sensitivity and independence are correlated with the amount of contextual information contained in drawings, and with the order in which the focal and background objects are drawn. The results supported these hypotheses, and inspection of the regression relationships suggested that the intergroup variations in test performance were likely to result from differences in the attention accorded to contextual information, as revealed by the drawings. Social and environmental explanations for the group differences in context sensitivity are also discussed. The conclusions support the argument that cultural differences in artistic styles and perceptual tests reflect the same underlying perceptual tendencies, and they are consistent with the argument that these tendencies reflect corresponding differences in patterns of social and environmental interaction.

    Full Text Available OBJECTIVE: to identify the changes which had occurred over the last year in the life of older adults, as well as the values attributed to these changes.METHOD: this is a multicentric, cross-sectional study, of the inquiry type, undertaken in three cities of the Brazilian Northeast, investigating two distinct groups of older adults.RESULTS: among the 236 older adults interviewed, it was observed that 30.0% reported health as the main change in their life course in the last year, this category being the most significant response among the older adults aged between 80 and 84 years old (37.7%. Changes in the family were mentioned by 11.5% of the older adults; death (9.6% and alterations in routine activities (9.6%. In relation to the value attributed to these changes, it was ascertained that for 64.7% of the older adults aged between 65 and 69 years old, these changes were positive. In the older group, 49.4% of the older adults believe that their changes were related to losses.CONCLUSION: the knowledge of the changes mentioned, the value attributed to these changes, and the self-evaluation of health provide information which assists in formulating actions which are more specific to the real needs of these age groups. They also provide the health professionals with a better understanding of how some experiences are experienced in the life trajectories of these older adults.

    In time, well water, as a source of drinking and coking water, with physical-chemical, bacteriological, and biological indicators suggestive of alteration in water potability, determines complex, sometimes irreversible, metabolic disorders. Sixty individuals residing in a rural community were divided into 2 groups: study group -30 subjects using well water, and control group--30 subjects using safe water. For the study group the selection criteria were: age, sex, use of well water as drinking and cooking water, history suggestive of chronic poisoning (pregnancy course, birth weight, susceptibility to infectious agents, and current chronic diseases). In the study group, gestosis, prematurity, and altered body mass index are more frequent as compared to the subjects in the control group. The identified laboratory changes indicate moderate anemia, hepatic cytolysis, dyslipidemia, presence of nitrites in urine, and positive urine cultures. Long-term use of water with mineral constituents in excess, absent, or inadequate, the direct biological and chemical water pollution, or most frequently the indirect pollution through the soil determine, in time, complex, sometimes irreversible, metabolic disorders.

  12. Comparative cytogenetics in Astyanax (Characiformes: Characidae with focus on the cytotaxonomy of the group

    Directory of Open Access Journals (Sweden)

    Renata Cristina Claudino de Oliveira Tenório

    Full Text Available Astyanax is a diverse group of Neotropical fishes, whose different forms occupy different environments. This great diversity is also reflected on cytogenetic aspects and molecular markers, which have repeatedly been demonstrated by cytogenetic studies. In order to characterize the karyotype of species of this genus, six species were studied: Astyanax altiparanae, A.argyrimarginatus, A. elachylepis, A. xavante, and two new species provisionally called Astyanax sp. and A. aff. bimaculatus. A detailed cytogenetic study based on conventional staining with Giemsa, AgNORs, C-banding, base-specific fluorochromes, and FISH using ribosomal genes 18S and 5S was conducted, aiming to understand some of the chromosomal mechanisms associated with the high diversification that characterizes this group and culminated with the establishment of these species. The results showed 2n = 50 chromosomes for five species and a karyotype with 52 chromosomes in Astyanax sp. Small variations in the macrostructure of the karyotypes were identified, which were quite relevant when analyzed by classical banding, fluorochromes, and FISH methods. These differences among Astyanax spp. (2n = 50 are largely due to changes in the amount and types of heterochromatic blocks. Astyanax sp (2n = 52, in addition to variations due to heterochromatic blocks, has its origin possibly by events of centric fission in a pair of chromosomes followed by minor rearrangements.These results show an interesting karyotypic diversity in Astyanax and indicate the need of a review of the group referred as A. aff. bimaculatus and the description of Astyanax sp., including the possibility of inclusion of this unit in another genus.

  16. Comparing the group theoretical approaches to the description of dipole and quadrupole collectivity in nuclei

    International Nuclear Information System (INIS)

    Georgieva, A I

    2013-01-01

    The comparison of the two types of collectivity in nuclear dynamics is based on the equal realizations of their basic symmetries, represented by the algebra-chain u(3) superset of su(3) superset of so(3). We illustrate this on the example of two phenomenological algebraic models: the semimicroscopic algebraic cluster model (SACM) with one of the clusters considered as a scalar and the interacting two vector boson model (IVBM). In both of them the root group structure that leads to the above chain is based on the coupling of two different U(3) representations, with different physical interpretations. These similarities allow for the use of the same mathematical tools in building the theory, but there are important differences that come from the different higher symmetries in which this equal substructures are embedded.

    To describe the study of the comparability of the measurements levels of biological tests processed in biochemistry in Catlab's 4 laboratories. Quality requirements, coefficients of variation and total error (CV% and TE %) were established. Controls were verified with the precision requirements (CV%) in each test and each individual laboratory analyser. Fresh serum samples were used for the comparability study. The differences were analysed using a Microsoft Access® application that produces modified Bland-Altman plots. The comparison of 32 biological parameters that are performed in more than one laboratory and/or analyser generated 306 Bland-Altman graphs. Of these, 101 (33.1%) fell within the accepted range of values based on biological variability, and 205 (66.9%) required revision. Data were re-analysed based on consensus minimum specifications for analytical quality (consensus of the Asociación Española de Farmacéuticos Analistas (AEFA), the Sociedad Española de Bioquímica Clínica y Patología Molecular (SEQC), the Asociación Española de Biopatología Médica (AEBM) and the Sociedad Española de Hematología y Hemoterapia (SEHH), October 2013). With the new specifications, 170 comparisons (56%) fitted the requirements and 136 (44%) required additional review. Taking into account the number of points that exceeded the requirement, random errors, range of results in which discrepancies were detected, and range of clinical decision, it was shown that the 44% that required review were acceptable, and the 32 tests were comparable in all laboratories and analysers. The analysis of the results showed that the consensus requirements of the 4 scientific societies were met. However, each laboratory should aim to meet stricter criteria for total error.

    Full Text Available Objective: This study compared the effectiveness of two group treatments, behavioral activation (BA and cognitive therapy (CT, in reducing subsyndromal anxiety and depressive symptoms in a sample of Iranian university students.Method: Twenty-seven Iranian university students who scored 18 or higher on the depression subscale and 16 or higher on the anxiety subscale of the Depression, Anxiety, and Stress Scale (DASS-42 were randomly assigned into treatment groups. One group received 8 sessions of BA (n = 14, and the other received 8 sessions of group CT (n = 13.Result: Analysis of covariance revealed that the BA group had a significantly greater reduction in depressive symptoms than the CT group. However, there were no significant differences between the two groups in the levels of anxiety, stress symptoms or functional impairment after treatment.Conclusion: This study found evidence for the effectiveness of BA in reducing anxiety, depressive and stress symptoms and functional impairment compared to CT. BA was more effective than CT in improving depressive symptoms and was as effective as CT in decreasing anxiety, stress and functional impairment. BA is also a cost-effective intervention, particularly in group formats.

    Two-stage clinical trial designs may be efficient in pharmacogenetics research when there is some but inconclusive evidence of effect modification by a genomic marker. Two-stage designs allow to stop early for efficacy or futility and can offer the additional opportunity to enrich the study population to a specific patient subgroup after an interim analysis. This study compared sample size requirements for fixed parallel group, group sequential, and adaptive selection designs with equal overall power and control of the family-wise type I error rate. The designs were evaluated across scenarios that defined the effect sizes in the marker positive and marker negative subgroups and the prevalence of marker positive patients in the overall study population. Effect sizes were chosen to reflect realistic planning scenarios, where at least some effect is present in the marker negative subgroup. In addition, scenarios were considered in which the assumed 'true' subgroup effects (i.e., the postulated effects) differed from those hypothesized at the planning stage. As expected, both two-stage designs generally required fewer patients than a fixed parallel group design, and the advantage increased as the difference between subgroups increased. The adaptive selection design added little further reduction in sample size, as compared with the group sequential design, when the postulated effect sizes were equal to those hypothesized at the planning stage. However, when the postulated effects deviated strongly in favor of enrichment, the comparative advantage of the adaptive selection design increased, which precisely reflects the adaptive nature of the design.

    Patients with a particular, steroid-sensitive headache and often characteristic pathology at orbital phlebography, have been suggested to suffer from venous vasculitis. Fifty such patients were examined with computed tomography (CT) of the brain. The findings were compared with those of an age-matched reference group selected at random to represent normal subjects. The CT examinations were analyzed with respect to size of lateral ventricles and signs of atrophy. In both groups, there was a significant increase of atrophy with age. There was also a significantly higher degree of atrophy in the patient group as compared with the reference group. The findings indicate that the supposedly underlying venous vasculitis is related to early aging and atrophy of the brain. (orig.)

    The present study focuses on comparing the effects of home-based (HB) and group-based (GB) physical activity on mental health in a sample of older adults in Shahr-e-kord. In this quasi-experimental study, a twice-weekly physical activity program for 2 months was provided either individually at home or in a group format for 181 people who were divided into two groups (HB and GB). The outcome, mental health, was measured with the 28-item General Health Questionnaire (GHQ-28). Mental health status improved after participation in the physical activity program. The decrease in GHQ-28 total score in GB group, 3 months after intervention, was 3.61 ± 2.28 (P effects of GB physical activity on mental health compared with HB physical activity, adjusted for related baseline variables, were significant. These findings reveal the probable effects of GB rather than HB physical activity on mental health among the elderly.

    The studies focused on age-related differences in emotional experience are still scarce, and most of them have been conducted with North-American samples. This study explores the presence of age-related differences in some facets of emotional experience (subjective well-being and emotional intensity), as well as in variables related to emotion regulation (subjective emotional control and three emotion-regulation mechanisms: situation selection, emotion suppression, rumination) in the Spanish population. One hundred and sixty people from three age groups (younger, middle-aged and older adults) participated in the study. Older participants reported lower levels of life satisfaction and positive emotional intensity than younger ones, as well as higher levels of perceived emotional control, emotional maturity and leveling of positive affect, and more use of emotion suppression. The results partially support the emotional maturity hypothesis of emotional functioning in old age, but also suggest that older adults' emotional regulation may present important peculiarities which have not yet been addressed in the extant literature, such as the moderation or limitation of emotional experience, especially positive emotions.

    Full Text Available Abstract Background In order to improve treatments for cannabis use disorder, a better understanding of factors associated with successful quitting is required. Method This study examined differences between successful (n = 87 and unsuccessful (n = 78 cannabis quitters. Participants completed a questionnaire addressing demographic, mental health, and cannabis-related variables, as well as quitting strategies during their most recent quit attempt. Results Eighteen strategies derived from cognitive behavioral therapy were entered into a principal components analysis. The analysis yielded four components, representing (1 Stimulus Removal, (2 Motivation Enhancement, (3 (lack of Distraction, and (4 (lack of Coping. Between groups comparisons showed that unsuccessful quitters scored significantly higher on Motivation Enhancement and (lack of Coping. This may indicate that unsuccessful quitters focus on the desire to quit, but do not sufficiently plan strategies for coping. Unsuccessful quitters also had significantly more symptoms of depression and stress; less education; lower exposure to formal treatment; higher day-to-day exposure to other cannabis users; and higher cannabis dependence scores. Conclusions The findings suggest that coping, environmental modification, and co-morbid mental health problems may be important factors to emphasize in treatments for cannabis use disorder.

    Full Text Available The purpose of this research is scientific rationale for fractional photothermolysis usage to correct age-related changes of neck skin of women in different age groups. Materials and Methods. A comparative study of the results for fractional photothermolysis (FP treatment in order to correct involutional changes in neck skin of 60 women in different age groups has been carried out (first group - 40-49 years old, second group - 50-60 years old. Skin moisture, its smoothness (relief, the width of the mouths of the pilosebaceous unit, the severity of pigmentation, the depth and width of wrinkles before the treatment, 1 week after and 1 month after the procedure have been investigated. Main results. After a week of having FP it affected all investigated functional skin parameters more in the 2nd age group than in the 1st one. Decreasing in moisture and smoothness of the skin, increasing the width and the depth of wrinkles, pores and pigmentation width have been marked. In one month there was more significant positive dynamics in parameters of smoothness, wrinkles width in the 2nd group (p -8, p -7 than in the 1st group (p = 0.002, p -5. Hydration of the skin, the width of the mouths of the pilosebaceous unit, the depth of wrinkles and pigmentation changed more significantly among patients in group 1 (p -7, p = 0.001, p -5, p -8. Conclusion. Skin functional parameters of patients from the first group deteriorated significantly less in comparison with the second group one week after PF procedure was carried out. 1 month after the 1st group is indicated with significant improvement in moisture, the width of the pilosebaceous unit, the depth of wrinkles and pigmentation, and the 2nd group is indicated with improvement of smoothness and width of wrinkles. The differences discovered in skin condition dynamics in different age groups should be considered when planning the aesthetic outcome of FP procedure.

    Full Text Available Reference isolates of Candida parapsilosis (n = 8, Candida metapsilosis (n = 6, Candida orthopsilosis (n = 7, and Lodderomyces elongisporus (n = 11 were analyzed to gain insight into their pathobiology and virulence mechanisms. Initial evaluation using BBL Chromagar Candida medium misidentified L. elongisporus isolates as C. albicans. Polymerase chain reaction analysis of isolate MTL idiomorphs revealed that all C. parapsilosis isolates were MTLa homozygous and no MTL α1, α2, a1, or a2 gene was detected in L. elongisporus isolates. For C. orthopsilosis, two isolates were MTLa homozygous and five were MTL-heterozygous. Similarly, one C. metapsilosis isolate was MTLα homozygous whereas five were MTL-heterozygous. Isolate phenotypic switching analysis revealed potential phenotypic switching in the MTLα homozygous C. metapsilosis isolate, resulting in concomitant elongated cell formation. Minimum inhibitory concentrations of fluconazole (FLC and FK506, alone or in combination, were determined by checkerboard assay, with data analyzed using the fractional inhibitory concentration index model. Synergistic or additive effects of these compounds were commonly observed in C. parapsilosis and L. elongisporus isolates. No killer activity was observed in the studied isolates, as determined phenotypically. No significant difference in virulence was seen for the four species in a Galleria mellonella model (P > 0.05. In conclusion, our results demonstrated phenotypic switching of C. metapsilosis CBS 2315 and that FLC and FK506 represent a promising drug combination against C. parapsilosis and L. elongisporus. The findings of the present study contribute to our understanding of the biology, diagnosis, and new possible treatments of the C. parapsilosis species group and L. elongisporus.

    Physical activity benefits cancer survivors, but the comparative effectiveness of a team-based delivery approach remains unexplored. The hypothesis tested was that a team-based physical activity intervention delivery approach has added physical and psychological benefits compared to a group-based approach. A team-based sport accessible to survivors is dragon boating, which requires no previous experience and allows for diverse skill levels. In a non-randomized trial, cancer survivors chose between two similarly structured 8-week programs, a dragon boat paddling team (n = 68) or group-based walking program (n = 52). Three separate intervention rounds were carried out in 2007-2008. Pre-post testing measured physical and psychosocial outcomes. Compared to walkers, paddlers had significantly greater (all p team cohesion, program adherence/attendance, and increased upper-body strength. For quality-of-life outcomes, both interventions were associated with pre-post improvements, but with no clear-cut pattern of between-intervention differences. These hypothesis-generating findings suggest that a short-term, team-based physical activity program (dragon boat paddling) was associated with increased cohesion and adherence/attendance. Improvements in physical fitness and psychosocial benefits were comparable to a traditional, group-based walking program. Compared to a group-based intervention delivery format, the team-based intervention delivery format holds promise for promoting physical activity program adherence/attendance in cancer survivors.

There was a prevalence of malnutrition of 32.1% in the institutionalized, 14.3% on the day house, and 3.5% in independent adult. Obesity were diagnosed in 93.2% of people by Waist/Height Ratio. Good correlations were found between body mass index (BMI and calf circumference (CC with MNA (p<0.05.Conclusions: High prevalences of undernutrition were found in nursing homes and user of day homes, with major risks in womans and people major of 80 years. The implementation of nutritional interventions depending on the type of social assistance received is required.

    Co-morbid anxiety and depression in older adults is associated with worse physical and mental health outcomes and poorer response to psychological and pharmacological treatments in older adults. However, there is a paucity of research focused on testing the efficacy of the co-morbid treatment of anxiety and depression in older adults using psychological interventions. Accordingly, the primary objective of the current study was to test the effects of a group cognitive behavior therapy (CBT) program in treating co-morbid anxiety and depression in a sample of older age adults. A total of 133 community-dwelling participants aged ⩾60 years (mean age = 67.35, s.d. = 5.44, male = 59) with both an anxiety disorder and unipolar mood disorder, as assessed on the Anxiety Disorder Interview Schedule (ADIS), were randomly allocated to an 11-week CBT group or discussion group. Participants with Mini-Mental State Examination scores <26 were excluded. Participants were assessed pre-treatment, post-treatment and at 6 months follow-up on the ADIS, a brief measure of well-being, Geriatric Anxiety Inventory and Geriatric Depression Scale. Both conditions resulted in significant improvements over time on all diagnostic, symptom and wellbeing measures. Significant group × time interaction effects emerged at post-treatment only for diagnostic severity of the primary disorder, mean severity of all anxiety disorders, mood disorders, and all disorders, and recovery rates on primary disorder. Group CBT produced faster and sustained improvements in anxiety and depression on diagnostic severity and recovery rates compared to an active control in older adults.

    Full Text Available Background: The effect of correcting static vision on sports vision is still not clear. Aim: To examine whether sports vision (depth perception [DP], dynamic visual acuity [DVA], eye movement [EM], peripheral vision [PV], and momentary vision [MV], were different among soft tennis adolescent athletes with normal vision (Group A, with refractive error and corrected with (Group B and without eyeglasses (Group C. Setting and Design: A cross-section study was conducted. Soft tennis athletes aged 10–13 who played softball tennis for 2–5 years, and who were without any ocular diseases and without visual training for the past 3 months were recruited. Materials and Methods: DPs were measured in an absolute deviation (mm between a moving rod and fixing rod (approaching at 25 mm/s, receding at 25 mm/s, approaching at 50 mm/s, receding at 50 mm/s using electric DP tester. A smaller deviation represented better DP. DVA, EM, PV, and MV were measured on a scale from 1 (worse to 10 (best using ATHLEVISION software. Statistical Analysis: Chi-square test and Kruskal–Wallis test was used to compare the data among the three study groups. Results: A total of 73 athletes (37 in Group A, 8 in Group B, 28 in Group C were enrolled in this study. All four items of DP showed significant difference among the three study groups (P = 0.0051, 0.0004, 0.0095, 0.0021. PV displayed significant difference among the three study groups (P = 0.0044. There was no significant difference in DVA, EM, and MV among the three study groups. Conclusions: Significant better DP and PV were seen among soft tennis adolescent athletes with normal vision than those with refractive error regardless whether they had eyeglasses corrected. On the other hand, DVA, EM, and MV were similar among the three study groups.

    Patients with type 2 diabetes mellitus and elevated urinary albumin:creatinine ratio (ACR) have increased risk of heart failure. We hypothesized this was because of cardiac tissue changes rather than silent coronary artery disease. In a case-controlled observational study 130 subjects including 50 ACR+ve diabetes mellitus patients with persistent microalbuminuria (ACR >2.5 mg/mol in males and >3.5 mg/mol in females, ≥2 measurements, no previous renin-angiotensin-aldosterone therapy, 50 ACR-ve diabetes mellitus patients and 30 controls underwent cardiovascular magnetic resonance for investigation of myocardial fibrosis, ischemia and infarction, and echocardiography. Thirty ACR+ve patients underwent further testing after 1-year treatment with renin-angiotensin-aldosterone blockade. Cardiac extracellular volume fraction, a measure of diffuse fibrosis, was higher in diabetes mellitus patients than controls (26.1±3.4% and 23.3±3.0% P =0.0002) and in ACR+ve than ACR-ve diabetes mellitus patients (27.2±4.1% versus 25.1±2.9%, P =0.004). ACR+ve patients also had lower E' measured by echocardiography (8.2±1.9 cm/s versus 8.9±1.9 cm/s, P =0.04) and elevated high-sensitivity cardiac troponin T 18% versus 4% ≥14 ng/L ( P =0.05). Rate of silent myocardial ischemia or infarction were not influenced by ACR status. Renin-angiotensin-aldosterone blockade was associated with increased left ventricular ejection fraction (59.3±7.8 to 61.5±8.7%, P =0.03) and decreased extracellular volume fraction (26.5±3.6 to 25.2±3.1, P =0.01) but no changes in diastolic function or high-sensitivity cardiac troponin T levels. Asymptomatic diabetes mellitus patients with persistent microalbuminuria have markers of diffuse cardiac fibrosis including elevated extracellular volume fraction, high-sensitivity cardiac troponin T, and diastolic dysfunction, which may in part be reversible by renin-angiotensin-aldosterone blockade. Increased risk in these patients may be mediated by

    Arterial hypertension is an important risk factor for cardiovascular outcomes. Blood pressure (BP) control levels remain largely out of target among primary healthcare (PHC) patients. Twenty-four-hour ambulatory blood pressure monitoring (ABPM) may contribute toward the identification of cardiovascular risk groups. To assess concordance between conventional office BP measurements and 24-h ABPM of hypertension control in cardiovascular risk groups of PHC hypertensive patients. A cross-sectional study with 569 hypertensive patients was carried out. The evaluation of BP was performed by a PHC doctor, and the 24-h ABPM was performed by a different and blinded provider. The therapeutic targets for BP followed the guidance of The Eighth Joint National Committee, the Brazilian guideline, and the 2013 European Society of Hypertension. Considering the hypertension control therapeutic targets, the guidelines were not similar and were used to evaluate differences in BP value concordances compared with BP standard measurements. After a multivariate logistic regression analysis, a conventional BP was used in comparison with ABPM in different cardiovascular risk groups of hypertensive patients. According to the ABPM by European Society of Hypertension guideline, the subgroup of inactive patients (P=0.006), with altered glycemia (P=0.015) and over 30 mg/dl albuminuria (P=0.001), presented discordance among methods. When a conventional BP measurement in comparison with the ABPM results according to the Brazilian ABPM guideline was used, the discordance occurred significantly in inactive (P=0.001) and microalbuminuria more than 30 mg/dl (P=0.022) subgroups. However, in this comparison, a concordance between high-density lipoprotein more than 60 mg/dl (P=0.015) and obesity (P=0.035) subgroups occurred. Uncontrolled glucose levels, a sedentary lifestyle, and the presence of microalbuminuria correspond to some cardiovascular risk groups that would particularly benefit from 24-h

    Few empirical studies have used a randomized controlled design to evaluate the impact of coaching, and there are even fewer that have compared coaching with other interventions. In the current field study, we investigated the relative effectiveness of coaching as an intervention to reduce procrastination. In a randomized controlled study, participants (N = 84) were assigned to an individual coaching, a self-coaching, a group training, or a control group condition. Results indicate that individual coaching and group training were effective in reducing procrastination and facilitating goal attainment. Individual coaching created a high degree of satisfaction and was superior in helping participants attaining their goals, whereas group training successfully promoted the acquisition of relevant knowledge. The results for the self-coaching condition show that independently performing exercises without being supported by a coach is not sufficient for high goal attainment. Moreover, mediation analysis show that a coach’s transformational and transactional leadership behavior influenced participants’ perceived autonomy support and intrinsic motivation, resulting in beneficial coaching outcomes. The results may guide the selection of appropriate human resource development methods: If there is a general need to systematically prepare employees to perform on specific tasks, group training seems appropriate due to lower costs. However, when certain aspects of working conditions or individual development goals are paramount, coaching might be indicated. However, further research is needed to compare the relative effectiveness of coaching with other interventions in different contexts. PMID:27199857

    Full Text Available Background: Oral isotretinoin is the only drug which promotes prolonged remission or cure of severe acne. The aim of our study was to estimate the isotretinoin exposure and to evaluate the effectiveness of the Polish and Romanian pregnancy prevention. This is a comparative study of two groups of women. Methods: A retrospective, comparative study of 569 women with acne vulgaris. The study included two groups of randomly selected women during treatment and follow-up. Group I with rigorous prevention of pregnancy; Group II without this rigor. Results: We did not register any pregnancies. 1.93% used oral contraceptives, 92.79% used a condom during sex, and 7.21% of women abstained from sex. The analysis showed significant differences (p <0.0001 total dose applied depending on the method of treatment. No statistically significant correlations were found between patients' age, duration of disease, location, and type of acne. Average length of therapy was 8.81 months. Isotretinoin therapy was interrupted for 27 patients from group I. Conclusion: The isotretinoin pregnancy prevention in Poland and Romania was very good during our study. Every woman in the fertile phase of life should use contraception while taking isotretinoin. The most important thing is the awareness of the patient.

    Behavioural problems in preschool (1-4 years) children are a common cause of referral to health services. Parents of children presenting to the child development unit with behavioural problems (n = 18) were compared with a control group (n = 45). A questionnaire was utilized to examine the parents' expectations of the children's behaviours. As might be expected, the parents of children presenting to the Unit rated their children as having more difficult behaviours. These parents had unrealistic expectations, particularly for the 'negative' behaviours (disobedience, temper tantrums, defiance and whinging). However, they were able to anticipate normal age-related difficulties in some problem areas (dawdling during mealtimes, masturbating, not sharing toys and being jealous of one's siblings). Counselling should address the issue of matching the expectations of parents with the individual rates of development of their children.

    To compare the attitudes toward smoking and smoking patterns of young male asthmatics with the attitudes and habits of a group previously studied non-asthmatic men. Volunteers responded individually to as anonymous questionnaire. Responses were received from 488 asthmatics men (55.83%) of the sample, with 11 not responding) and 386 non-asthmatics (44.16%, with 27 not responding). The mean age of subjects was 19.91 +/- 2.76 yr. Smoking asthmatics numbered 154 (31.56%) non-asthmatic smokers numbered 207 (53.6%) (p non-smoking asthmatics. The prevalence of smoking is lower among asthmatics than among non-asthmatics and asthmatics smoke fewer cigarettes/day and have a lower level of addiction. There are no differences in age of or reasons for starting to smoke. Asthmatics have fewer smoking friends than do non-asthmatics and non-smoking asthmatics have fever still. the desire to quit smoking is high in both groups.

    Economic evaluation from a societal perspective conducted alongside a randomized controlled trial with a follow-up of 52 weeks. To evaluate the cost effectiveness and cost utility of an intensive group training protocol compared with usual care physiotherapy in patients with nonspecific chronic low back pain. The intensive group training protocol combines exercise therapy, back school, and behavioral principles. Two studies found a significant reduction in absenteeism for a graded activity program in occupational health care. This program has not yet been evaluated in a primary care physiotherapy setting. Participating physical therapists in primary care recruited 114 patients with chronic nonspecific low back pain. Eligible patients were randomized to either the protocol group or the guideline group. Outcome measures included functional status (Roland Morris Disability Questionnaire), pain intensity (11-point numerical rating scale), general perceived effect and quality of life (EuroQol-5D). Cost data were measured with cost diaries and included direct and indirect costs related to low back pain. After 52 weeks, the direct health care costs were significantly higher for patients in the protocol group, largely due to the costs of the intervention. The mean difference in total costs amounted to [Euro sign] 233 (95% confidence interval: [Euro sign] -2.185; [Euro sign] 2.764). The cost-effectiveness planes indicated no significant differences in cost effectiveness between the 2 groups. The results of this economic evaluation showed no difference in total costs between the protocol group and the guideline group. The differences in effects were small and not statistically significant. At present, national implementation of the protocol is not recommended.

    COMPAR works on FORTRAN arrays with four indices: A = A(i,j,k,l) where, for each fixed k 0 ,l 0 , only the 'plane' [A(i,j,k 0 ,l 0 ), i = 1, isub(max), j = 1, jsub(max)] is held in fast memory. Given two arrays A, B of this type COMPAR has the capability to 1) re-norm A and B ind different ways; 2) calculate the deviations epsilon defined as epsilon(i,j,k,l): =[A(i,j,k,l) - B(i,j,k,l)] / GEW(i,j,k,l) where GEW (i,j,k,l) may be chosen in three different ways; 3) calculate mean, standard deviation and maximum in the array epsilon (by several intermediate stages); 4) determine traverses in the array epsilon; 5) plot these traverses by a printer; 6) simplify plots of these traverses by the PLOTEASY-system by creating input data blocks for this system. The main application of COMPAR is given (so far) by the comparison of two- and three-dimensional multigroup neutron flux-fields. (orig.) [de

    The aim of the present study was to compare and assess the oral health status of 12-year-old children from two socially disadvantaged groups in the Udupi district of South India. A total of 327 children were examined in Ashrama schools, and 340 children were randomly selected for comparison from other government schools. Modified WHO proforma was used for clinical examination. Oral hygiene practices, dental fluorosis, periodontal status, dentition status and dentofacial anomalies were assessed and compared. Chi square test was used for comparison between categorical variables and Mann-Whitney test for comparison between two groups for quantitative variables. P u 0.05 was considered as statistically significant. Dental fluorosis was detected in 22.9% children from Ashrama schools, whereas in the comparison group 14.4% children had dental fluorosis (P u 0.001). Mean Decayed teeth and DMFT value in Ashrama school children were 1.15 ± 1.62, and 1.15 ± 1.62, respectively. In the comparison group, the corresponding values were 0.46 ± 0.98 and 0.48 ± 1.04, respectively (P u 0.001). The mean number of sextants in the Ashrama school children with Community Periodontal Index score 2 was 2.00 ± 1.53, whereas in the comparison group it was 1.31 ± 1.53 (P u 0.001). No significant differences were noted between two groups with respect to Dental Aesthetic Index scores. The present study revealed higher levels of dental caries experience, untreated dental disease and social disadvantage of the children attending Ashrama schools, providing evidence for the need to address the health inequalities of these children.

    Cognitive-linguistic deficits often accompany traumatic brain injury (TBI) and can negatively impact communicative competency. The linguistic sequelae underpinning mild TBI (MTBI) remain largely unexplored in contemporary literature. The present research methods aim to provide group evidence pertaining to the influence of MTBI on linguistic and higher-level language processing. Extrapolating on the findings of recent case reports, it is hypothesized that performance of the MTBI patients will be significantly reduced compared to normal controls performance on the employed high-level linguistic tasks. Sixteen patients with MTBI and 16 age- and education-matched normal control participants were assessed using a comprehensive battery of cognitive-linguistic assessments. The results demonstrated statistically significant differences between MTBI and normal control group performance across a number of higher-level linguistic, general cognitive and general language tasks. MTBI group performance was significantly lower than the normal control group on tasks requiring complex lexical semantic operations and memory demands, including: Recall, organization, making inferences, naming and perception/discrimination. These outcomes confer that post-MTBI, cognitive, high-level language and isolated general language performance (e.g. naming) is significantly reduced in MTBI patients, compared to normal controls. Furthermore, the detailed cognitive-linguistic profile offered provides a necessary direction for the identification of areas of linguistic decline in MTBI and targets for therapeutic intervention of impaired cognitive-linguistic processes to ultimately improve communicative outcomes in MTBI.

    Cognitive abilities likely evolved in response to specific environmental and social challenges and are therefore expected to be specialized for the life history of each species. Specialized cognitive abilities may be most readily engaged under conditions that approximate the natural environment of the species being studied. While naturalistic environments might therefore have advantages over laboratory settings for cognitive research, it is difficult to conduct certain types of cognitive tests in these settings. We implemented methods for automated cognitive testing of monkeys (Macaca mulatta) in large social groups (Field station) and compared the performance to that of laboratory-housed monkeys (Laboratory). The Field station animals shared access to four touch-screen computers in a large naturalistic social group. Each Field station subject had an RFID chip implanted in each arm for computerized identification and individualized assignment of cognitive tests. The Laboratory group was housed and tested in a typical laboratory setting, with individual access to testing computers in their home cages. Monkeys in both groups voluntarily participated at their own pace for food rewards. We evaluated performance in two visual psychophysics tests, a perceptual classification test, a transitive inference test, and a delayed matching-to-sample memory test. Despite the differences in housing, social environment, age, and sex, monkeys in the two groups performed similarly in all tests. Semi-free ranging monkeys living in complex social environments are therefore viable subjects for cognitive testing designed to take advantage of the unique affordances of naturalistic testing environments.

    Peer relationships improve for children with autism spectrum disorder (ASD) in clinic-based social skills groups but rarely generalize to real world contexts. This study compares child outcomes of two social skills interventions conducted in schools with children in Kindergarten through fifth grade. Children with ASD were randomized to one of two interventions that varied on group composition (mixed typical and ASD vs. all ASD or social difficulties) and intervention approach (didactic SKILLS based vs. activity-based ENGAGE groups). Interventions were implemented at school for 8 weeks (16 sessions) with an 8-week follow-up. Innovative measures of peer nomination and playground peer engagement, as well as teacher reports of child behavior problems and teacher-child relationship were analyzed for 137 children with ASD across four sites. On the primary outcome of social network connections from the peer nomination measure, there was no main effect of treatment, but there were moderator effects. Children with low teacher-child closeness or high conflict improved more in their social connections if they received the SKILLS intervention, whereas children with higher teacher-child closeness improved more if they received the ENGAGE intervention. Only two secondary outcome measures yielded significant effects of treatment. Children in the SKILLS groups increased peer engagement and decreased isolation during recess. Child behavior problems and teacher-child closeness moderated peer engagement such that children with higher behavior problems and lower closeness benefitted more from SKILLS groups. These findings suggest that social skills groups conducted at school can affect both peer engagement during recess as well as peer acceptability. Child characteristics and teacher-child relationship prior to intervention yield important information on who might benefit from a specific social skills intervention. © 2015 Association for Child and Adolescent Mental Health.

    To determine the effectiveness of Pilates and yoga group exercise interventions for individuals with chronic neck pain (CNP). Quasi-randomised parallel controlled study. Community, university and private practice settings in four locations. Fifty-six individuals with CNP scoring ≥3/10 on the numeric pain rating scale for >3 months (controls n=17, Pilates n=20, yoga n=19). Exercise participants completed 12 small-group sessions with modifications and progressions supervised by a physiotherapist. The primary outcome measure was the Neck Disability Index (NDI). Secondary outcomes were pain ratings, range of movement and postural measurements collected at baseline, 6 weeks and 12 weeks. Follow-up was performed 6 weeks after completion of the exercise classes (Week 18). NDI decreased significantly in the Pilates {baseline: 11.1 [standard deviation (SD) 4.3] vs Week 12: 6.8 (SD 4.3); mean difference -4.3 (95% confidence interval -1.64 to -6.7); PPilates and yoga group exercise interventions with appropriate modifications and supervision were safe and equally effective for decreasing disability and pain compared with the control group for individuals with mild-to-moderate CNP.

    With continued population growth and increasing use of fresh groundwater resources, protection of this valuable resource is critical. A cost effective means to assess risk of groundwater contamination potential will provide a useful tool to protect these resources. Integrating geospatial methods offers a means to quantify the risk of contaminant potential in cost effective and spatially explicit ways. This research was designed to compare the ability of intrinsic (DRASTIC) and specific (Attenuation Factor; AF) vulnerability models to indicate groundwater vulnerability areas by comparing model results to the presence of pesticides from groundwater sample datasets. A logistic regression was used to assess the relationship between the environmental variables and the presence or absence of pesticides within regions of varying vulnerability. According to the DRASTIC model, more than 20% of the study area is very highly vulnerable. Approximately 30% is very highly vulnerable according to the AF model. When groundwater concentrations of individual pesticides were compared to model predictions, the results were mixed. Model predictability improved when concentrations of the group of similar pesticides were compared to model results. Compared to the DRASTIC model, the AF model more accurately predicts the distribution of the number of contaminated wells within each vulnerability class.

    The purpose of this study was to evaluate if young people with insidious-onset neck pain who spend long periods on mobile electronic devices (known as "text neck") have impaired cervical proprioception and if this is related to time on devices. A 2-group comparative observational study was conducted at an Australian university. Twenty-two participants with text neck and 22 asymptomatic controls, all of whom were 18 to 35 years old and spent ≥4 hours per day on unsupported electronic devices, were assessed using the head repositioning accuracy (HRA) test. Differences between groups were calculated using independent sample t-tests, and correlations between neck pain intensity, time on devices, and HRA test were performed using Pearson's bivariate analysis. During cervical flexion, those with text neck (n = 22, mean age ± standard deviation [SD]: 21 ± 4 years, 59% female) had a 3.9° (SD: 1.4°) repositioning error, and the control group (n = 22, 20 ± 1 years, 68% female) had a 2.9° (SD: 1.2°) error. The mean difference was 1° (95% confidence interval: 0-2, P = .02). For other cervical movements, there was no difference between groups. There was a moderately significant correlation (P ≤ .05) between time spent on electronic devices and cervical pain intensity and between cervical pain intensity and HRA during flexion. The participants with text neck had a greater proprioceptive error during cervical flexion compared with controls. This could be related to neck pain and time spent on electronic devices.

    Given the rise in depression disorders in adolescence, it is important to develop and study depression prevention programs for this age group. The current study examined the efficacy of Interpersonal Psychotherapy-Adolescent Skills Training (IPT-AST), a group prevention program for adolescent depression, in comparison to group programs that are typically delivered in school settings. In this indicated prevention trial, 186 adolescents with elevated depression symptoms were randomized to receive IPT-AST delivered by research staff or group counseling (GC) delivered by school counselors. Hierarchical linear modeling examined differences in rates of change in depressive symptoms and overall functioning from baseline to the 6-month follow-up assessment. Cox regression compared rates of depression diagnoses. Adolescents in IPT-AST showed significantly greater improvements in self-reported depressive symptoms and evaluator-rated overall functioning than GC adolescents from baseline to the 6-month follow-up. However, there were no significant differences between the two conditions in onset of depression diagnoses. Although both intervention conditions demonstrated significant improvements in depressive symptoms and overall functioning, results indicate that IPT-AST has modest benefits over groups run by school counselors which were matched on frequency and duration of sessions. In particular, IPT-AST outperformed GC in reduction of depressive symptoms and improvements in overall functioning. These findings point to the clinical utility of this depression prevention program, at least in the short-term. Additional follow-up is needed to determine the long-term effects of IPT-AST, relative to GC, particularly in preventing depression onset.

    Osteochondral allograft transplantation (OCA) is often performed with concomitant meniscus allograft transplantation (MAT) as a strategy for knee joint preservation, although to date, the effect of concomitant MAT on outcomes and failure rates after OCA has not been assessed. To determine clinical outcomes for patients undergoing OCA with MAT as compared with a matched cohort of patients undergoing isolated OCA. Control study; Level of evidence, 3. Patients who underwent OCA of the medial or lateral femoral condyle without concomitant MAT by a single surgeon were compared with a matched group of patients who underwent OCA with concomitant MAT (ipsilateral compartment). The patients were matched per age, sex, body mass index, and number of previous ipsilateral knee operations ±1. Patient-reported outcomes, complications, reoperations, and survival rates were compared between groups. One hundred patients undergoing OCA (50 isolated, 50 with MAT) with a mean ± SD follow-up of 4.9 ± 2.7 years (minimum, 2 years) were included (age, 31.7 ± 9.8 years; 52% male). Significantly more patients underwent OCA to the medial femoral condyle (n = 59) than the lateral femoral condyle (n = 41, P OCA. There were no significant differences between the groups regarding reoperation rate (n = 18 for OCA with MAT, n = 17 for OCA without MAT, P = .834), time to reoperation (2.2 ± 2.4 years for OCA with MAT, 3.4 ± 2.7 years for OCA without MAT, P = .149), or failure rates (n = 7 [14%] for OCA with MAT, n = 7 [14%] for OCA without MAT, P > .999). There were no significant differences in patient-reported clinical outcome scores between the groups at final follow-up. There was no significant difference in failure rates between patients undergoing medial femoral condyle OCA (n = 12, 15.3%) and lateral femoral condyle OCA (n = 5, 12.2%, P = .665). These results imply that with appropriate surgical indications to address meniscus deficiency in patients otherwise indicated for OCA and

    The measurement of patient satisfaction is crucial to enhancing customer service and competitive advantage in the health-care industry. While there are numerous approaches to such measurement, this paper provides a case study which compares and contrasts patient and staff perceptions of customer service using both survey and focus group data. Results indicate that there is a high degree of correlation between staff and patient perceptions of customer service based on both survey and focus group data. However, the staff and patient subgroups also provided complementary information regarding patient perceptions of their service experience. Staff members tended to have more negative perceptions of service attributes than did the patients themselves. The focus group results provide complementary information to survey results in terms of greater detail and more managerially relevant information. While these results are derived from a pilot study, they suggest that diversification of data sources beyond patient surveys may enhance the utility of customer service information. If further research can affirm these findings, they create exciting possibilities for gathering valid, reliable and cost-effective customer service information.

    The variability of the dust concentration in time and space, as well as the change of worker's place during the working process, define the necessity of introducing personal sampling in the hygiene control practice. However, the laboratory equipment with personal devices is still not sufficient. The aim of this work is to assess the dust exposure of the basic professional groups from the ore- and coal production in Bulgaria by personal sampling in comparative studies of the static ambient sampling used up to now. 63 full-shift investigations of the dust factor were performed on professional groups of miners of the polymetal and coal pits by static ambient devices-[Hygitest production] and personal [from firms "Casella", "Strolein" and "Gilian"] devices, after standardized methods. The results are data processed-by means of logarithmic normal distribution of the relation of the respirable dust concentrations, determined personally and by static ambient sampling. The limits of variation of this correlation are from 0.5 to 4.1 at average geometric value -0.95 and standard geometric deviation-1.8 i.e. both types of sampling are intersubstitutional for the examined groups and sites, as in the underground ores the professional risk of respirable dust is underestimated up to 4 times at static ambient sampling.

    Most epidemiologic studies of potential health impacts of mobile phones rely on self-reported information, which can lead to exposure misclassification. We compared self-reported questionnaire data among 60 participants, and phone billing records over a 3-year period (2002-2004). Phone usage information was compared by the calculation of the mean and median number of calls and duration of use, as well as correlation coefficients and associated P-values. Average call duration from self-reports was slightly lower than billing records (2.1 min vs. 2.8 min, P = 0.01). Participants reported a higher number of average daily calls than billing records (7.9 vs. 4.1, P = 0.002). Correlation coefficients for average minutes per day of mobile phone use and average number of calls per day were relatively high (R = 0.71 and 0.69, respectively, P correlations between self-reported mobile phone usage and billing records and substantial variability in recall are consistent with previous studies. However, the direction of over- and under-reporting was not consistent with previous research. We did not observe increased variability over longer periods of recall or a pattern of lower accuracy among older age groups compared with younger groups. Study limitations included a relatively small sample size, low participation rates, and potential limited generalizability. The variability within studies and non-uniformity across studies indicates that estimation of the frequency and duration of phone use by questionnaires should be supplemented with subscriber records whenever practical. © 2010 Wiley-Liss, Inc.

    Procrastination is a common problem among university students, with at least half of the population reporting great difficulties initiating or completing tasks and assignments. Procrastination can have a negative impact on course grades and the ability to achieve a university degree, but can also lead to psychological distress. Cognitive behavior therapy (CBT) is believed to reduce procrastination, but few studies have investigated its effectiveness in a regular clinical setting. The current study explored its effects using a pragmatic randomized controlled trial comparing treatment delivered during 8 weeks as self-guided CBT via the Internet (ICBT) or as group CBT. In total, 92 university students with severe procrastination were included in the study (registered as a clinical trial on Clinicaltrials.gov: NCT02112383). Outcome measures on procrastination, depression, anxiety, and well-being were distributed at pre- and posttreatment as well as 6-month follow-up. An outcome measure of procrastination was administered weekly. Linear mixed and fixed effects models were calculated, along with improvement and deterioration rates. The results showed large within-group effect sizes on procrastination, Cohen's d of 1.29 for ICBT, 95% Confidence Interval (CI) [0.81, 1.74], and d of 1.24 for group CBT, 95% CI [0.76, 1.70], and small to moderate benefits for depression, anxiety, and well-being. In total, 33.7% were regarded as improved at posttreatment and 46.7% at follow-up. No differences between conditions were observed after the treatment period, however, participants in group CBT continued or maintained their improvement at follow-up, while participants in self-guided ICBT showed some signs of deterioration. The findings from the current study suggest that CBT might be an effective treatment for those struggling with severe procrastination, but that a group format may be better for some to sustain their benefits over time and that the clinical significance of the

    A new method, comparative keyword analysis, is used to compare the language of men and women with cancer in 97 research interviews and two popular internet based support groups for people with cancer. The method is suited to the conjoint qualitative and quantitative analysis of differences between large bodies of text, an alternative to the 'code and retrieval' approach used in much thematic analysis of qualitative materials. Web forums are a rich source of data about illness experience and gender differences. Marked differences in the performance of gender are evident. These differences follow linguistic and other behavioural patterns (such as social network differences) established in other contexts. Men with prostate cancer indicate in research interviews that they are more likely to seek information on the internet; women with breast cancer that they are more likely to seek social and emotional support. Men's concerns cluster around treatment information, medical personnel and procedures. Their experience of disease is more localised on particular areas of the body, while women's experience is more holistic. Women's forum postings orientate much more towards the exchange of emotional support, including concern with the impact of illness on a wide range of other people. Women's use of superlatives as well as words referring to feelings indicate their enactment of greater emotional expressivity. Web forums are platforms for an intensification of men's knowledge gathering activities. Web forums, though actually quite publicly visible, appear to be subjectively experienced by both sexes as relatively private places for the exchange of intimate personal information. The 'privacy' of the breast cancer forum facilitated interactions found in other studies to be characteristic of women's friendship groups.

    This post hoc meta-analysis evaluated the efficacy and safety of desvenlafaxine 50 and 100 mg versus placebo across age groups and severity of depression at baseline in patients with major depressive disorder. Data from placebo and desvenlafaxine 50-mg and 100-mg dose arms were pooled from 9 short-term, placebo-controlled, major depressive disorder studies (N = 4279). Effects of age (18-40 years, >40 to depression severity (mild, 17-item Hamilton Rating Scale for Depression total score [HAM-D17] ≤18; moderate, HAM-D17 >18 to depression and function compared with placebo for patients 18 to 40 years, older than 40 to younger than 55 years, and 55 to younger than 65 years, with no significant evidence of an effect of age. Desvenlafaxine significantly improved most measures of depression and function in moderately and severely depressed patients. There was a significant baseline severity by treatment interaction for HAM-D17 total score only (P = 0.027), with a larger treatment effect for the severely depressed group. Desvenlafaxine significantly improved depressive symptoms in patients younger than 65 years and in patients with moderate or severe baseline depression. Sample sizes were not adequate to assess desvenlafaxine efficacy in patients 65 years or older or with mild baseline depression.

    Full Text Available We report a comparative investigation of the antibacterial activity of two water-soluble fullerene derivatives bearing protonated amine (AF and deprotonated carboxylic (CF groups appended to the fullerene cage via organic linkers. The negatively charged fullerene derivative CF showed no tendency to bind to the bacterial cells and, consequently, no significant antibacterial activity. In contrast, the compound AF loaded with cationic groups showed strong and partially irreversible binding to the negatively charged Escherichia coli K12 TG1 cells and to human erythrocytes, also possessing negative zeta potential. Adsorption of AF on the bacterial surface was visualized by atomic force microscopy revealing the formation of specific clusters (AF aggregates surrounding the bacterial cell. Incubation of E. coli K12 TG1 with AF led to a dose-dependent bactericidal effect with LD50 = 79.1 µM. The presence of human erythrocytes in the test medium decreased the AF antibacterial activity. Thus we reveal that the water-soluble cationic fullerene derivative AF possesses promising antibacterial activity, which might be utilized in the development of novel types of chemical disinfectants.

    2012-01-01

    Full Text Available Some antihypertensive drugs have also renoprotective and anti-inflammatory properties that go beyond their effect on blood pressure. It has been suggested that microalbuminuria and glomerular filtration rate (GFR are associated with circulating levels of the soluble form of the receptor, sRAGE (soluble receptor for advanced glycation ends-products. In the present analysis, we used data from the TALENT study to evaluate soluble receptor for advanced glycation end-products (sRAGE plasma levels in patients with hypertension and high-cardiovascular risk-treated nifedipine and telmisartan in combination. Treatment with nifedipine-telmisartan significantly decreased mean systolic and diastolic ambulatory blood pressure and resulted in a significant increase in sRAGE plasma concentrations after 24 weeks of therapy. We concluded that in hypertensive patients with early-stage renal disease, sRAGE concentrations are not influenced by either microalbuminuria or GFR. Long-term treatment with a combination of nifedipine-telmisartan may have a beneficial effect increasing sRAGE plasma levels, thus exerting an atheroprotective and anti-inflammatory activity.

    In neuropsychological research, single-cases are often compared with a small control sample. Crawford and colleagues developed inferential methods (i.e., the modified t-test) for such a research design. In the present article, we suggest an extension of the methods of Crawford and colleagues employing linear mixed models (LMM). We first show that a t-test for the significance of a dummy coded predictor variable in a linear regression is equivalent to the modified t-test of Crawford and colleagues. As an extension to this idea, we then generalized the modified t-test to repeated measures data by using LMMs to compare the performance difference in two conditions observed in a single participant to that of a small control group. The performance of LMMs regarding Type I error rates and statistical power were tested based on Monte-Carlo simulations. We found that starting with about 15-20 participants in the control sample Type I error rates were close to the nominal Type I error rate using the Satterthwaite approximation for the degrees of freedom. Moreover, statistical power was acceptable. Therefore, we conclude that LMMs can be applied successfully to statistically evaluate performance differences between a single-case and a control sample.

    DNA repair capacity is essential in maintaining cellular functions and homeostasis. Identification of genetic polymorphisms responsible for reduced DNA repair capacity may allow better cancer prevention. Double strand break repair pathway plays critical roles in maintaining genome stability. Present study was conducted to determine distribution of XRCC3 Exon 7 (C18067T, rs861539) and XRCC7 Intron 8 (G6721T, rs7003908) gene polymorphisms in North Indian population and compare with different populations globally. The genotype assays were performed in 224 normal healthy individuals of similar ethnicity using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Allelic frequencies of wild type were 79% (C) in XRCC3 Exon 7 C > T and 57% (G) in XRCC7 Intron 8 (G > T) 57% (G) observed. On the other hand, the variant allele frequency were 21% (T) in XRCC3 Exon 7 C > T and 43% (T) in XRCC7 Intron 8 G > T respectively. Major differences from other ethnic populations were observed. Our results suggest that frequency in these DNA repair genes exhibit distinctive pattern in India that could be attributed to ethnicity variation. This could assist in high-risk screening of humans exposed to environmental carcinogens and cancer predisposition in different ethnic groups.

    DNA repair capacity is crucial in maintaining cellular functions and homeostasis. However, it can be altered based on DNA sequence variations in DNA repair genes and this may lead to the development of many diseases including malignancies. Identification of genetic polymorphisms responsible for reduced DNA repair capacity is necessary for better prevention. Homologous recombination (HR), a major double strand break repair pathway, plays a critical role in maintaining the genome stability. The present study was performed to determine the frequency of the HR gene XRCC3 Exon 7 (C18067T, rs861539) polymorphisms in Saudi Arabian population in comparison with epidemiological studies by "MEDLINE" search to equate with global populations. The variant allelic (T) frequency of XRCC3 (C>T) was found to be 39%. Our results suggest that frequency of XRCC3 (C>T) DNA repair gene exhibits distinctive patterns compared with the Saudi Arabian population and this might be attributed to ethnic variation. The present findings may help in high-risk screening of humans exposed to environmental carcinogens and cancer predisposition in different ethnic groups.

    Background and purpose: The purpose of this work was a comparison of realistic IMRT plans based on the same CT-image data set and a common predefined set of dose objectives for the planning target volume and the organs at risk. This work was part of the larger European QUASIMODO IMRT verification project. Materials and methods: Eleven IMRT plans were produced by nine different European groups, each applying a representative set of clinically used IMRT treatment planning systems. The plans produced were to be deliverable in a clinically acceptable treatment time with the local technical equipment. All plans were characterized using a set of different quality measures such as dose-volume histograms, number of monitor units and treatment time. Results: Only one plan was able to fulfil all dose objectives strictly; six plans failed some of the objectives but were still considered to be clinically acceptable; four plans were not able to reach the objectives. Additional quality scores such as the number of monitor units and treatment time showed large variations, which mainly depend on the delivery technique. Conclusion: The presented planning study showed that with nearly all presently available IMRT planning and delivery systems comparable dose distributions could be achieved if the planning goals are clearly defined in advance

    The definitive diagnosis of spotted fever group (SFG) rickettsioses in humans is challenging due to the retrospective nature and cross reactivity of the serological methods and the absence of reliable and consistent samples for molecular diagnostics. Existing data indicate the transient character of bacteremia in experimentally infected animals. The ability of arthropod vectors to acquire rickettsial infection from the laboratory animals in the absence of systemic infection and known tropism of rickettsial agents to endothelial cells of peripheral blood vessels underline the importance of local infection and consequently the diagnostic potential of skin samples. In order to evaluate the diagnostic sensitivity of rickettsial DNA detection in blood and skin samples, we compared results of PCR testing in parallel samples collected from model laboratory animals infected with Rickettsia rickettsii, Rickettsia parkeri and Rickettsia slovaca-like agent at different time points after infection. Skin samples were collected from ears - away from the site of tick placement and without eschars. Overall, testing of skin samples resulted in a higher proportion of positive results than testing of blood samples. Presented data from model animals demonstrates that testing of skin samples from sites of rickettsial proliferation can provide definitive molecular diagnosis of up to 60-70% of tick-borne SFG rickettsial infections during the acute stage of illness. Detection of pathogen DNA in cutaneous samples is a valuable alternative to blood-PCR at least in model animals. Published by Elsevier GmbH.

    The most common modality of diffusion MRI used in the ageing and development studies is diffusion tensor imaging (DTI) providing two key measures, fractional anisotropy and mean diffusivity. Here, we investigated diffusional changes occurring between childhood (average age 10.3 years) and mitddle adult age (average age 54.3 years) with the help of diffusion kurtosis imaging (DKI), a recent novel extension of DTI that provides additional metrics quantifying non-Gaussianity of water diffusion in brain tissue. We performed voxelwise statistical between-group comparison of diffusion tensor and kurtosis tensor metrics using two methods, namely, the tract-based spatial statistics (TBSS) and the atlas-based regional data analysis. For the latter, fractional anisotropy, mean diffusivity, mean diffusion kurtosis, and other scalar diffusion tensor and kurtosis tensor parameters were evaluated for white matter fibres provided by the Johns-Hopkins-University Atlas in the FSL toolkit (http://fsl.fmrib.ox.ac.uk/fsl/fslwiki/Atlases). Within the same age group, all evaluated parameters varied depending on the anatomical region. TBSS analysis showed that changes in kurtosis tensor parameters beyond adolescence are more widespread along the skeleton in comparison to the changes of the diffusion tensor metrics. The regional data analysis demonstrated considerably larger between-group changes of the diffusion kurtosis metrics than of diffusion tensor metrics in all investigated regions. The effect size of the parametric changes between childhood and middle adulthood was quantified using Cohen's d. We used Cohen's d related to mean diffusion kurtosis to examine heterogeneous maturation of various fibres. The largest changes of this parameter (interpreted as reflecting the lowest level of maturation by the age of children group) were observed in the association fibres, cingulum (gyrus) and cingulum (hippocampus) followed by superior longitudinal fasciculus and inferior longitudinal

    Impaired ability to recall specific autobiographical memories is characteristic of depression, which when reversed, may have therapeutic benefits. This cluster-randomized controlled pilot trial investigated efficacy and aspects of acceptability, and feasibility of MEmory Specificity Training (MEST) relative to Psychoeducation and Supportive Counselling (PSC) for Major Depressive Disorder (N = 62). A key aim of this study was to determine a range of effect size estimates to inform a later phase trial. Assessments were completed at baseline, post-treatment and 3-month follow-up. The cognitive process outcome was memory specificity. The primary clinical outcome was symptoms on the Beck Depression Inventory-II at 3-month follow-up. The MEST group demonstrated greater improvement in memory specificity relative to PSC at post-intervention (d = 0.88) and follow-up (d = 0.74), relative to PSC. Both groups experienced a reduction in depressive symptoms at 3-month follow-up (d = 0.67). However, there was no support for a greater improvement in depressive symptoms at 3 months following MEST relative to PSC (d = -0.04). Although MEST generated changes on memory specificity and improved depressive symptoms, results provide no indication that MEST is superior to PSC in the resolution of self-reported depressive symptoms. Implications for later-phase definitive trials of MEST are discussed. Copyright © 2018 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Pedogenic and non-pedogenic calcrete facies are very common feature of Marilia (Brazil) and Mercedes (Uruguay) formations in the Parana Basin. The non-pedogenic ones constitute massive limestone facies that have been recently interpreted as groundwater calcretes. These limestones are exploited in both countries to supply raw materials to Portland cement and soil conditioner in origin and age of calcretization phenomena. In Uruguay, the calcretization process seens to be band formation. Field relationships and fossil assemblage point to a Paleocene (or later) age for the calcretization. In Brazilian territory, the groundwater calcretes aresupposed to be of Upper Cretaceous age due to the presence of dinosaurs scattered through the Bauru Group, including siliciclastic beds below and above the calcretes. The authors assume that calcretization processes are similar in both countries (host rocks, intensity, size, textures, geometries and economic potential). The main difference is in age of the calcretization. (author)

    presence of microalbuminuria (MAU), that is an amount of albumin in the urine of 30-300 mg/day or an albumin/creatinine ratio, preferentially on morning spot urine, of 30-300 mg/g.There is clear evidence that urinary albumin excretion levels, even below the cut-off values used to define MAU, are associated with an increased risk of CV events. The relationships of MAU with a variety of risk factors, such as blood pressure, diabetes and metabolic syndrome and with several indices of subclinical organ damage, may contribute, at least in part, to explain the enhanced CV risk conferred by MAU. Nonetheless, several studies showed that the association between MAU and CV disease remains when all these risk factors are taken into account in multivariate analyses. Therefore, the exact pathophysiological mechanisms explaining the association between MAU and CV risk remain to be elucidated. The simple search for MAU and in general of subclinical renal involvement in hypertensive patients may enable the clinician to better assess absolute CV risk, and its identification may induce physicians to encourage patients to make healthy lifestyle changes and perhaps would prompt to more aggressive modification of standard CV risk factors.

    To evaluate differences anatomical location and age groups on CT and clinical data in deep neck abscess. This study included 200 patients who underwent CT and were diagnosed with a deep neck abscess, from December 2005 to July 2010. Patients were divided into four groups by age (children, adolescent, adult, elderly). Next, the anatomic location, location multiplicity and clinical data regarding the deep neck abscesses were analyzed retrospectively. The deep neck abscesses observed were defined as superficial or deep and partitioned into sub-groups, with further analysis of their clinical data. The incidence of the parapharyngeal abscess was more frequent in children and elderly groups (p < 0.05). The masticator abscess was only observed among patients in the elderly group (p < 0.05). Multiple locations were observed with increased frequency in children and elderly groups (p < 0.05). Swelling in the neck was more frequently observed in children and elderly groups (p < 0.05), cervical lymphadenitis was frequently seen in children and adolescent groups (p < 0.05), and the incidence of symptoms including sore throat were significantly increased in adolescent and adult groups (p < 0.05). Location multiplicity was significantly higher in parapharyngeal, retropharyngeal, submandibular, danger, visceral and masticator spaces than other spaces (p < 0.05). With regards to anatomic location, neck swelling was more frequent in superficial group and sore throat was more frequent in deep group (p < 0.05). Deep neck abscess would show significant differences with regards to the abscess location, location multiplicity, and clinical symptoms according to age. The clinical symptoms observed are dependent on the anatomic location as defined by a superficial or deep abscess.

    Oligopeptide mapping of 35 S-methionine labeled non-stuctural (NS1) proteins of 23 influenza A virus strains showed the presence of both common and variable oligopeptides. Analysis of the oligopeptide maps revealed at least four groups of NS1 proteins. The first group includes NS1 proteins of several human H1N1 influenza viruses (that were designated as H0N1 according to the old classification). The second group is composed of NS1 proteins of H1N1 and H2N2 viruses. The third group includes NS1 proteins of H3N2 human influenza viruses. The fourth group is composed of NS1 proteins of five avian influenza viruses and an equine (H3N8) influenza virus. Two animal influenza viruses A/equi/Prague/56 (H7N7) and A/duck/England/56 (H11N6) contain NS1 proteins that belong to the second group. (Author)

    In recent years endoscopic surgery has became a highly demanded procedure because it is an easy method for diagnosis and treatment in gynecological field. Post-operative pain is considered as a condition in the morbidity status. The objective of this study was to evaluate the nociceptive suppression in laparoscopic surgery. A prospective randomized trial was performed in order to evaluate this condition. A total of 45 patients were included. Three groups were randomized using two different anesthetics applied in the cult-de-sac and uterine-bladder union. Group A (n-15) received bupivacaine, group B (n = 15) ropivacaine and group C (control) saline solution was instilled. The pain was scored using the visual analog scale as same as blood pressure and heart rate in a 15 minute intervals in the recovery room. For study design there were no differences in age, weight, height and body mass index (EMI). The surgical and anesthetic times were similar among groups. However there were significant differences when pain was evaluated. For a less toxic effects and good preventive analgesia we recommend to use ropivacaine in the postoperative status.

    To compare, through analysis of the coronary artery calcium (CAC) score and the risk factors for atherosclerosis, the characteristics of acute coronary syndrome between an asymptomatic high-risk group of atherosclerosis patients and a chronic coronary arterial obstructive disease(CAOD) group. The CAC scores of an asymptomatic high-risk group of atherosclerosis patients (group I, n=284), a chronic CAOD croup (group II, n=39) and an acute coronary syndrome group (group III, n=21) were measured by electron beam tomography. Forty-seven patients with CAOD from groups II and III underwent coronary angiography, and we scrutinized age, sex and risk factors including diabetes mellitus, hypertension, obesity, smoking, hypercholesterolemia and low high-density lipoproteinemia. The numbers of stenotic coronary arterial branches and degree of stenosis revealed by coronary angiography were also recorded. We determined the differences between the three groups in terms of CAC score and the risk factors, the relationship between CAC score and risk factors, and the characteristic features of each type of CAOD group. The mean CA score of group III (135.1) was not statistically different from that of group I (135.7) or group II (365.8). Among patients aged below 50, the mean CAC score of group III (127.4) was significantly higher than that of group I (6.2), (p=0.0006). The mean CAC score at the sixth decade was also significantly different between group I(81.5) and group II (266.9). The mean age of group III (54.2 years) was significantly lower than that of group I (58.1 years) (p=0.047) and of group II (60.1) (p=0.022). There was significant correlation between the number of stenotic coronary arterial branches and log(CAC +1) (p<.01). The square root of the CAC score and the maximal degree of stenosis was also well correlated (p<.01). There was no difference in the mean number of risk factors among the three groups, though the incidence of smoking in group III was significantly

    Full Text Available Objective: Our previous study, a 6-month randomised controlled trial, demonstrated that a group-based support promoted weight loss as compared to an education-only intervention. The purpose of this study was to examine weight loss maintenance for 2 years. Methods: Originally, 188 overweight Japanese adults, aged 40-65 years, were randomly assigned to 3 groups: control, education-only or group-based support. After the 6-month intervention, 125 participants in the education-only and the group-based support groups were followed up for 2 years. The primary outcome was the amount of weight lost. The participants were retrospectively grouped into quartiles of percent weight loss for secondary analyses. Results: At the end of follow-up, the amount of weight lost in the education-only and the group-based support groups was the same (3.3 kg. Secondary analyses using data of those who completed the study (n = 100 revealed that the participants in the highest quartile of percent weight loss significantly increased their step counts and moderate-to-vigorous physical activity compared with the lowest quartile. No significant differences were observed in the energy intake among the four groups. Conclusion: The effects of group-based support disappear within 2 years. Increasing physical activity may be a crucial factor for successful maintenance of weight loss.

    To explore the acceptability of a telephone- or a group-delivered diabetes prevention program for women with previous gestational diabetes and to compare the characteristics associated with program engagement. Postpartum women participated in a lifestyle modification program delivered by telephone (n=33) or group format (n=284). Semi-structured interviews on barriers and enablers to program engagement (defined as completing≥80% sessions) were conducted before (Group) and after (Group and Telephone) interventions. The Health Action Process Approach theory was used as the framework for inquiry. Psychological measures were compared between engagement subgroups before and after group-delivered intervention. In the telephone-delivered program 82% participants met the engagement criteria compared with 38% for the group-delivered program. Engaged participants (Group) had significantly higher risk perception, outcome expectancy, and activity self-efficacy at baseline (P<0.05). There was a greater decrease in body weight (-1.45±3.9 vs -0.26±3.5, P=0.024) and waist circumference (-3.56±5.1 vs -1.24±5.3, P=0.002) for engaged vs non-engaged participants following group program completion. Telephone delivery was associated with greater engagement in postpartum women. Engagement was associated with greater reduction in weight and waist circumference. Further studies are required to confirm the effectiveness of telephone-delivered program for diabetes prevention in postpartum women. Copyright © 2017 Elsevier B.V. All rights reserved.

    Low socio-economic group patients from rural areas often opt for free cataract surgeries offered by charitable organisations. SICS continues to be a time tested technique for cataract removal in such patients. In recent times, camp patients are sometimes treated by clear corneal phacoemulsification with implantation of a rigid IOL, which being more cost effective is often provided for camp patients. This study was undertaken to find out which surgical technique yielded better outcomes and was more suited for high volume camp surgery. To find the better surgical option- phacoemulsification with rigid IOL or SICS, in poor patients from rural areas. A prospective randomised controlled trial of cataract patients operated by two different techniques. One hundred and twelve eyes were selected and were randomly allocated into two groups of 56 eyes each. At completion of the study, data was analysed for 52 eyes operated by clear corneal phacoemulsification and implantation of a rigid IOL, and 56 eyes operated by SICS. Unpaired t-test was used to calculate the p- value. The results were evaluated on the following criteria. The mean post-operative astigmatism at the end of four weeks - was significantly higher in phacoemulsification group as compared to SICS group The BCVA (best corrected visual acuity) at the end of four weeks - was comparable in both groups. Subjective complaints and/ or complications: In phaco group two patients required sutures and seven had striate keratitis , while none in SICS group. Complaint of irritation was similar in both groups. Surgical time- was less for SICS group as compared to phaco group. SICS by virtue of being a faster surgery with more secure wound and significantly less astigmatism is a better option in camp patients from rural areas as compared to phacoemulsification with rigid IOL.

    Urinary tract infections (UTIs) are one of the most common infectious diseases in humans and domestic animals such as pigs. The most frequent infectious agent in such infections is Escherichia coli. Virulence characteristics of E. coli UTI strains range from highly virulent pyelonephritis strains...... to relatively benign asymptomatic bacteriuria strains. Here we analyse a spectrum of porcine and human UTI E. coli strains with respect to their antibiotic resistance patterns and their phylogenetic groups, determined by multiplex PCR. The clonal profiles of the strains differed profoundly; whereas human...

    Although the risk of graphene materials to aquatic organisms has drawn wide attention, the combined effects of graphene materials with other contaminants such as toxic metals, which may bring about more serious effects than graphene materials alone, have seldom been explored. Herein, the effects of graphene (GN) and graphene oxide (GO, an important oxidized derivative of graphene) on copper (Cu) toxicity to Daphnia magna were systematically investigated. The results indicated that GN remarkably increased the Cu accumulation in D. magna and enhanced the oxidative stress injury caused by Cu, whereas did not significantly alter D. magna acute mortality within the tested Cu concentrations (0-200 μg L -1 ). On the contrary, GO significantly decreased the Cu accumulation in D. magna and alleviated the oxidative stress injury caused by Cu. Meanwhile, the presence of GO significantly reduced the mortality of D. magna when Cu concentration exceeded 50 μg L -1 . The different effects of GN and GO on Cu toxicity were possibly dependent on the action of surface oxygenic functional group. Because of the introduction of surface oxygenic functional groups, the adsorption ability to metal ions, stability in water and interaction mode with organisms of GO are quite different from that of GN, causing different effects on Cu toxicity. This study provides important information on the bioavailability and toxicity of heavy metals as affected by graphene materials in natural water. Copyright © 2017 Elsevier Ltd. All rights reserved.

    New classes of two-dimensional (2D) materials beyond graphene, including layered and non-layered, and their heterostructures, are currently attracting increasing interest due to their promising applications in nanoelectronics, optoelectronics and clean energy, where thermal transport is a fundamental physical parameter. In this paper, we systematically investigated the phonon transport properties of the 2D orthorhombic group IV-VI compounds of GeS, GeSe, SnS and SnSe by solving the Boltzmann transport equation (BTE) based on first-principles calculations. Despite their similar puckered (hinge-like) structure along the armchair direction as phosphorene, the four monolayer compounds possess diverse anisotropic properties in many aspects, such as phonon group velocity, Young's modulus and lattice thermal conductivity (κ), etc. Especially, the κ along the zigzag and armchair directions of monolayer GeS shows the strongest anisotropy while monolayer SnS and SnSe show almost isotropy in phonon transport. The origin of the diverse anisotropy is fully studied and the underlying mechanism is discussed in details. With limited size, the κ could be effectively lowered, and the anisotropy could be effectively modulated by nanostructuring, which would extend the applications to nanoscale thermoelectrics and thermal management. Our study offers fundamental understanding of the anisotropic phonon transport properties of 2D materials, and would be of significance for further study, modulation and applications in emerging technologies.

    The attributes of social ecological systems affect the management of commons. Strengthening and enhancing social capital and the enforcement of rules and sanctions aid in the collective action of communities in forest fire management. Using a set of variables drawn from previous studies on the management of commons, we conducted a study across 20 community forest user groups in Central Siwalik, Nepal, by dividing the groups into two categories based on the type and level of their forest fire management response. Our study shows that the collective action in forest fire management is consistent with the collective actions in other community development activities. However, the effectiveness of collective action is primarily dependent on the complex interaction of various variables. We found that strong social capital, strong enforcement of rules and sanctions, and users' participation in crafting the rules were the major variables that strengthen collective action in forest fire management. Conversely, users' dependency on a daily wage and a lack of transparency were the variables that weaken collective action. In fire-prone forests such as the Siwalik, our results indicate that strengthening social capital and forming and enforcing forest fire management rules are important variables that encourage people to engage in collective action in fire management.

    To compare the effects of Internet-based exercise on glycaemic control, blood lipids, body composition, physical activity level, functional capacity, and quality of life with supervised group exercise in patients with type 2 diabetes. Single-blind, randomized controlled study. A Faculty of Health Sciences. A total of 65 patients with type 2 diabetes (47 women, 18 men). Group A ( n = 22), control group - physical activity counselling once with a brochure. Group B ( n = 22), supervised group-based exercise, three days per week for eight weeks. Group C ( n = 21), Internet-based exercise following the same programme via a website. Primary outcomes - glycosylated haemoglobin, fasting blood glucose, high-density and low-density lipoprotein, triglyceride, and cholesterol. Secondary outcomes - waist and hip circumferences, body mass index, number of steps, six-minute walking test, and Euro-Quality of Life-5 Dimension. After treatment, glycaemic control (mean change for Group B; Group C; -0.80%, -0.91%, P = 0.003), waist circumference (-4.23 cm, 5.64 cm, P = 0.006), and quality of life (0.26, 0.15, P = 0.013) significantly improved in both training groups compared with the control group. Fasting blood glucose (-46.86 mg/dL, P = 0.009) and hip circumference (-2.7 cm, P = 0.011) were significantly decreased in Group B and total cholesterol (-16.4 mg/dL, P = 0.028), six-minute walking distance (30.5 m, P = 0.01), and number of steps (1258.05, P = 0.023) significantly improved in Group C compared with control group. Group B and Group C changed with equal magnitude. In type 2 diabetes, supervised group-based and Internet-based exercise can improve equally glycaemic control, waist circumference, and quality of life, and both are better than simply counselling.

    Aims were to assess the efficacy of metacognitive training (MCT) in people with a recent onset of psychosis in terms of symptoms as a primary outcome and metacognitive variables as a secondary outcome. A multicenter, randomized, controlled clinical trial was performed. A total of 126 patients were randomized to an MCT or a psycho-educational intervention with cognitive-behavioral elements. The sample was composed of people with a recent onset of psychosis, recruited from nine public centers in Spain. The treatment consisted of eight weekly sessions for both groups. Patients were assessed at three time-points: baseline, post-treatment, and at 6 months follow-up. The evaluator was blinded to the condition of the patient. Symptoms were assessed with the PANSS and metacognition was assessed with a battery of questionnaires of cognitive biases and social cognition. Both MCT and psycho-educational groups had improved symptoms post-treatment and at follow-up, with greater improvements in the MCT group. The MCT group was superior to the psycho-educational group on the Beck Cognitive Insight Scale (BCIS) total (p = 0.026) and self-certainty (p = 0.035) and dependence self-subscale of irrational beliefs, comparing baseline and post-treatment. Moreover, comparing baseline and follow-up, the MCT group was better than the psycho-educational group in self-reflectiveness on the BCIS (p = 0.047), total BCIS (p = 0.045), and intolerance to frustration (p = 0.014). Jumping to Conclusions (JTC) improved more in the MCT group than the psycho-educational group (p = 0.021). Regarding the comparison within each group, Theory of Mind (ToM), Personalizing Bias, and other subscales of irrational beliefs improved in the MCT group but not the psycho-educational group (p tolerance to frustration. It seems that MCT could be useful to improve symptoms, ToM, and personalizing bias.

    Women diagnosed and surgically treated for regional breast cancer (N = 190) were studied to determine the sexual and body change sequelae for women receiving modified radical mastectomy (MRM) with breast reconstruction in comparison with the sequelae for women receiving breast-conserving therapy (BCT) or MRM without breast reconstruction. The sexuality pattern for women receiving reconstructive surgery was one that was significantly different—with lower rates of activity and fewer signs of sexual responsiveness—than that for women in either of the other groups. Significantly higher levels of traumatic stress and situational distress regarding the breast changes were reported by the women receiving an MRM in contrast to the women treated with BCT. Using a model to predict sexual morbidity, regression analyses revealed that individual differences in sexual self-schema were related to both sexual and body change stress outcomes. PMID:10965644

    Provision of antiretroviral treatment (ART) to people living with HIV (PLWH) has increased globally. Research measuring whether ART restores subjective well-being to "normal" levels is lacking, particularly in resource limited settings. The study objectives are to compare quality of life and depression symptoms for PLWH on ART to a general community population and to explore factors to explain these differences, including socio-economic status and the impact of urban or rural residence. PLWH on ART (n = 263) were recruited from ART delivery sites and participants not on ART (n = 160) were recruited from communities in Wakiso District, Uganda. Participants were interviewed using the translated World Health Organisation Quality of Life brief measure, the Hopkins Symptom Checklist depression section, and questions about socio-economic status, residence as urban or rural and, for PLWH on ART, self-reported adherence and use of HIV counselling. Compared to the community sample and controlling for location of residence, PLWH on ART had significantly higher quality of life (QOL) for physical, psychological and environment domains, but not the social domain. These differences were not due to socio-economic status alone. Depression scores were significantly lower for PLWH on ART. Both comparisons controlled for the effect of location of residence. People on ART self-reported high adherence and the majority had used HIV counselling services. Our findings show better QOL amongst PLWH on ART compared to a general community sample, which cannot be explained solely by differences in socio-economic status nor location of residence. The general community sample results point towards the challenges of life in this setting. Access to health services may underpin this difference and further research should explore this finding, in addition to identification of psychological mechanisms that relate to better QOL. ART provision infrastructure has clear benefits. Further work

    Objective To assess the effect of survey distribution protocol (mail versus handout) on data quality and measurement of patient care experiences. Data Sources/Study Setting Multisite randomized trial of survey distribution protocols. Analytic sample included 2,477 patients of 15 clinicians at three practice sites in New York State. Data Collection/Extraction Methods Mail and handout distribution modes were alternated weekly at each site for 6 weeks. Principal Findings Handout protocols yielded an incomplete distribution rate (74 percent) and lower overall response rates (40 percent versus 58 percent) compared with mail. Handout distribution rates decreased over time and resulted in more favorable survey scores compared with mailed surveys. There were significant mode–physician interaction effects, indicating that data cannot simply be pooled and adjusted for mode. Conclusions In-office survey distribution has the potential to bias measurement and comparison of physicians and sites on patient care experiences. Incomplete distribution rates observed in-office, together with between-office differences in distribution rates and declining rates over time suggest staff may be burdened by the process and selective in their choice of patients. Further testing with a larger physician and site sample is important to definitively establish the potential role for in-office distribution in obtaining reliable, valid assessment of patient care experiences.

    Full Text Available Establishment of laboratory colony is essential for mosquito-borne-disease research. Mating behavior of stenogamous Anopheles peditaeniatus and seven eurygamous species (Anopheles argyropus, Anopheles crawfordi, Anopheles nigerrimus, Anopheles nitidus, Anopheles paraliae (=An. lesteri, Anopheles pursati and Anopheles sinensis, were investigated and compared in this study. The self-mating success of adult mosquitoes in different size cages at two density resting surface (DRS values, 3.6 and 7.2, was statistically significant between stenogamous and eurygamous species. The results obtained from comparative measurements of specific characters in adult females (maxillary palpomere and antennal sensilla characters and males (wing and genitalia indicate those characters might influence the mating success of An. peditaeniatus in a small cage. The gonostylus of An. peditaeniatus was shorter than the eurygamous species. Additionally, the lower frequency of clasper movement and shorter mating time could be important mechanisms that control the stenogamous behavior of An. peditaeniatus. Interestingly, for the first time, a cluster of large sensilla coeloconica was recorded on the antenna of An. argyropus and An. peditaeniatus females. There was no statistically significant difference in the mean number per female of those large antennal sensilla coeloconica among six of the eurygamous species.

    Self-medication with antibiotics may result in antimicrobial resistance and its high prevalence is of particular concern in Low to Middle Income Countries (LMIC) like Guatemala. A better understanding of self-medication with antibiotics may represent an opportunity to develop interventions guiding the rational use of antibiotics. We aimed to compare the magnitude of antibiotic self-medication and the characteristics of those who self-medicate in two pharmacies serving disparate socio-economic communities in Guatemala City. We conducted a descriptive, cross-sectional study in one Suburban pharmacy and one City Center pharmacy in Guatemala City. We used a questionnaire to gather information about frequency of self-medication, income and education of those who self-medicate. We compared proportions between the two pharmacies, using two-sample z-test as appropriate. Four hundred and eighteen respondents completed the survey (221 in the Suburban pharmacy and 197 in the City Center pharmacy). Most respondents in both pharmacies were female (70%). The reported monthly income in the suburban pharmacy was between $1,250.00-$2,500.00, the city-center pharmacy reported a monthly income between $125.00- $625.00 (p Guatemala City. Additionally, self-medicating respondents were most often women and most commonly self-medicated with amoxicillin. Our findings support future public health interventions centered on the regulation of antibiotic sales and on the potential role of the pharmacist in guiding prescription with antibiotics in Guatemala.

    Significant differences in clinical profile and comorbidity patterns have been observed between "juvenile-onset" and "adult-onset" obsessive-compulsive disorder (OCD). There is little systematic research on onset of OCD after the fourth decade. The current study aims to compare the demographic, clinical, and comorbidity patterns of patients with "juvenile-onset" (OCD. Eight hundred two consecutive patients who consulted a specialty OCD clinic at a tertiary care hospital in India were evaluated with the Mini International Neuropsychiatric Interview, the Yale-Brown Obsessive-Compulsive Scale, and the Clinical Global Impression scale. 37.4%, 57.4%, and 5.2% of patients had juvenile-, adult-, and late-onset OCD, respectively. Late-onset OCD was associated with female gender (χ2=42, pOCD in first-degree relatives (χ2=20.4, pOCD was significantly associated with female gender, collecting compulsions, and less aggressive obsessions, in comparison with adult-onset OCD. In comparison with juvenile-onset, late-onset OCD was significantly associated with female gender, presence of precipitating factors, and less aggressive obsessions, sexual obsessions, and repeating compulsions. Late-onset OCD is characterized by female gender, lesser familial loading for OCD, and presence of precipitating factors, suggesting that it may have a distinct pathophysiology compared to juvenile- and adult-onset OCD. Systematic research is required to understand the family-genetic, neuropsychological, and neurobiological correlates of late-onset OCD.

    The nature of the effects of the low-doses from ionizing radiation has been the subject of considerable interest in the scientific community. The deleterious health effects caused by the relatively high doses of radiation led to the belief that radiation was harmful at all doses. Afterwards, the concept of the threshold dose explained that negative health effects were observed only at certain dose levels. Furthermore, it has been suggested that low doses of ionizing radiation might have beneficial effects on organisms leading to an hermetic effect of these low doses. The specific objectives of the study were to compute the morbidity (prevalence) of cancer among the radiation occupational workers and their families and to compare with suitable controls and to study prevalence of congenital anomalies among the offspring of the employees of the nuclear power plants in India and to determine, if any, their causal relation with radiation exposure

    By means of first-principles calculations, the adsorption and transport properties of lithium (Li) in orthorhombic group IV-VI compounds MX (M = Ge, Sn; X = S, Se) and GeS/graphene heterostructures have been systematically investigated. Strong interactions and distinct charge transfer between Li and compounds MX are observed. The Li diffusion barriers along the zigzag direction are found to be much lower than that along the armchair direction in monolayer and bulk MX, showing distinct anisotropic diffusion features. In particular, monolayer GeS has a lowest barrier of 0.173 eV (zigzag) among them and it will transit from a semiconductor to a metallic state after Li intercalation, indicating fast Li and electron transport properties. As a comparison, the addition of graphene in a GeS/graphene heterostructure could enhance its binding with Li, decrease the Li diffusion barrier and inhibit the volume expansion dramatically, suggesting a potential performance improvement. Our study not only reveals the directional transport properties of Li in MX, but also improves the understanding of the role of graphene in the MX/graphene heterostructure, and shows great potential application in the field of electrode materials.

    The 3500 lignite seam at the Gibbons Creek Mine in Grimes County, TX was sampled for pollen and spores at 10 cm intervals. The majority of samples are dominated (to 60%) by Momipites from the Juglandaceae (walnut family), as is typical of Jackson Group sediments. Other palynomorph taxa vary systematically, with a peak of pollen of the freshwater tree Nyssa (blackgum) and associated Rboipites angustus (to 17%) occurring at the base. Higher in the seam, increase (to 55%) of Cupuliferoipollenites (a chestnut-like grain) and Cyrillaceae-pollenites? ventosus (to 7%) percentages may indicate a higher salinity environment. A Chrysophyllum (satin leaf) peak (to 25%) near the top of the seam suggests relatively shallow fresh-water conditions. Core samples from an interval above the lignites represent a transgressive-regressive cycle in inner shelf clastics. These samples were taken at 40 cm or greater intervals and reveal the regional pollen flora. Although minor changes occur, palynomorph spectra are for the most part homogenous. The dominant grain is again Momipites coryloides, but in general percentages are lower (to 35%). Cupuliferoipollenites (to 17%), Chrysophyllum (to 5%), and Rhoipites angustus (to 3%) are not less important, but do not peak as they do in the lignite spectra. Palm leaf megafossils; in one sample suggest a clastic wetland; in this sample palm pollen (mostly Arecipites, representing the modern saw palmetto) reaches 73%. Another sample contains high (26%) percentages of the fern spore Lygodiumsporites adriennis. High percentages of these two taxa do not occur in the lignite samples.

    As India rapidly urbanizes, within urban areas socioeconomic disparities are rising and health inequality among urban children is an emerging challenge. This paper assesses the relative contribution of socioeconomic factors to child health inequalities between the less developed Empowered Action Group (EAG) states and more developed South Indian states in urban India using data from the 2005-06 National Family Health Survey. Focusing on urban health from varying regional and developmental contexts, socioeconomic inequalities in child health are examined first using Concentration Indices (CIs) and then the contributions of socioeconomic factors to the CIs of health variables are derived. The results reveal, in order of importance, pronounced contributions of household economic status, parent's illiteracy and caste to urban child health inequalities in the South Indian states. In contrast, parent's illiteracy, poor economic status, being Muslim and child birth order 3 or more are major contributors to health inequalities among urban children in the EAG states. The results suggest the need to adopt different health policy interventions in accordance with the pattern of varying contributions of socioeconomic factors to child health inequalities between the more developed South Indian states and less developed EAG states.

    The aim of the study was to compare knowledge and awareness of heart attacks/heart disease and perceived risk for future heart attack in Asian/Pacific Islander women, compared to other racial and ethnic groups. In this cross-sectional study, 318 women enrolled in a mobile phone-based physical activity education trial were analyzed. Heart attack knowledge, self-efficacy for recognizing and responding to heart attack symptoms, and perceived risk for a future heart attack were measured. Analyses were conducted using logistic, proportional odds, and linear regression models, depending on the outcome and adjusting for age. Pairwise differences between Asian/Pacific Islanders and the other four groups were assessed using a Bonferroni correction (p Asian/Pacific Islander women had significantly lower total scores for knowledge of heart attack and self-efficacy for heart attack recognition and care seeking behavior compared to the Caucasian women (p = 0.001 and p = 0.002, respectively). However, perceived risk did not differ among the groups. Forty-six percent of the Asian American women, compared to 25% of Caucasian women, falsely believed "breast cancer is the number one cause of death for women (p = 0.002)." In addition, Asian/Pacific Islander women were less likely to report "arm pain, numbness, tingling, or radiating" as one of the heart attack symptoms compared to the Caucasian and the multiracial group (34%, 63% [p Asian/Pacific Islander women and Caucasian women.

    Does the socioeconomic status (SES) that one's (ego's) network members (alters) occupy indicate social resources or social comparison standards in the dynamics of health across culture? Using nationally representative data simultaneously collected from the United States and urban China, this study examines two competing theories-social capital and comparative reference group-in the two societies and compares their different application across the two societies using two cultural explanations, relational dependence and self-evaluation motive. Social capital theory expects absolute accessed SES and the size of higher accessed socioeconomic positions to protect health, and the size of lower accessed socioeconomic positions to harm health. But comparative reference group theory predicts the opposite. Additionally, the relational dependence explanation anticipates social capital theory to be more applicable to urban China and comparative reference group theory to be more applicable to the United States. The self-evaluation motive explanation expects the same pattern across the two societies in the examination of the size of lower accessed socioeconomic positions but the opposite pattern in the analysis of absolute accessed SES and the size of higher accessed socioeconomic positions. This study focuses on depressive symptoms and measures accessed occupational status. Results are consistent with the self-evaluation motive explanation. They support both social capital theory and comparative reference group theory in the United States but only the latter theory in urban China. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Matrix metalloproteinases have a range of biological functions, including the liberation of cytokines and membrane-bound receptors, with roles in promotion of tumor invasion and angiogenesis. Several polymorphisms in MMPs have been implicated in the development of cancer as well as other diseases. Since their frequency distributions in the general North Indian population is not known the present study was conducted with the focus on MMP-1(-519) Aandgt; G, MMP-1(-1607) 1Gandgt; 2G, and MMP-7(-181) Aandgt; G gene polymorphisms. PCR-based analysis was conducted for 200 normal healthy individuals of similar ethnicity. Allelic frequencies in wild type of MMP-1(-519) Aandgt; G were 71.2% A; MMP-1(-1607) 1Gandgt; 2G 48.2% 1G; MMP-7(-181) Aandgt; G 60.7% A. The variant allele frequencies were 29% A in MMP-1(-519) Aandgt; G; 52% 2G in MMP-1(-1607) 1Gandgt; 2G; and 39.3% G in MMP-7(-181) Aandgt; G respectively. We further compared frequency distribution for these genes with various published studies in different ethnicity globally. Our results suggest that frequency in these MMP genes exhibit distinctive patterns in India that could perhaps be attributed to ethnic variation. This study is important as it can form a baseline for screening individuals who are at high risk when exposed to environmental carcinogens. More emphasis is needed on evaluating polymorphisms, alone or in combination, as modifiers of risk from relevant environmental/lifestyle exposures.

    To evaluate and compare the temporal changes in pulse waveform parameters of ocular blood flow (OBF) between non-habitual and habitual groups due to caffeine intake. This study was conducted on 19 healthy subjects (non-habitual 8; habitual 11), non-smoking and between 21 and 30 years of age. Using laser speckle flowgraphy (LSFG), three areas of optical nerve head were analyzed which are vessel, tissue, and overall, each with ten pulse waveform parameters, namely mean blur rate (MBR), fluctuation, skew, blowout score (BOS), blowout time (BOT), rising rate, falling rate, flow acceleration index (FAI), acceleration time index (ATI), and resistive index (RI). Two-way mixed ANOVA was used to determine the difference between every two groups where p groups in several ocular pulse waveform parameters, namely MBR (overall, vessel, tissue), BOT (overall), rising rate (overall), and falling rate (vessel), all with p group, but not within the habitual group. The temporal changes in parameters MBR (vessel, tissue), skew (overall, vessel), BOT (overall, vessel), rising rate (overall), falling rate (overall, vessel), and FAI (tissue) were significant for both groups (habitual and non-habitual) in response to caffeine intake. The experiment results demonstrated caffeine does modulate OBF significantly and response differently in non-habitual and habitual groups. Among all ten parameters, MBR and BOT were identified as the suitable biomarkers to differentiate between the two groups.

    Although Molluscum contagiosum (MC) is a self-limiting condition, active therapy could prevent further spread and improve cosmesis. Most of the available treatment modalities traumatize the lesions and have to be undertaken in the hospital, therefore evoking panic in children. In the quest for an alternative therapy, this study comparing 10% potassium hydroxide (KOH) solution and 5% imiquimod cream was taken up. To compare the efficacy and tolerability of 10% KOH and 5% imiquimod in the treatment of MC. This comparative study was conducted over a period of 18 months from October 2011 to March 2013, 40 patients between the age group of 1-18 years with clinically diagnosed MC were divided into two groups (lottery method), 20 patients were treated with 5% imiquimod cream (Group A) and the other 20 were treated with 10% KOH solution (Group B). Patients were followed up on the 4(th), 8(th) and 12(th) week of treatment. At the end of 12 weeks, out of 20 patients who received 10% KOH, 17 patients showed complete disappearance, whereas out of 20 patients who received 5% imiquimod, only 10 patients showed total clearance of the lesions. Adverse events were more frequent with 10% KOH, pigmentary disturbances being the most common. With only minor adverse effects, 10% KOH is an inexpensive and efficient modality for the treatment of MC in the pediatric age group. Although 5% imiquimod was effective in clearing the lesions with minimal adverse effects, the longer duration required for its efficacy may deter its wider use.

    1992-01-01

    An Advisory Group Meeting convened by the IAEA in October 1992 made recommendations on the setting up of a Co-ordinated Research Programme (CRP) using nuclear and isotopic techniques for international comparative studies of osteoporosis. The proposed CRP will be implemented by the IAEA during the period 1993-1997. The main purpose of this programme is to undertake pilot studies of bone density in selected developing country populations for the purposes of (i) determining the age of peak bone mass in each study group, and (ii) quantifying differences in bone density as functions of the age and sex of persons in the study groups, as well as quantifying differences between the study groups in different countries. The preferred technique for bone density measurements in this study is DEXA (dual energy X-ray absorptiometry). Additional measurements of trace elements in bone (and possibly also teeth) are also foreseen using neutron activation analysis and other appropriate techniques

    Full Text Available Context: Heart Rate Variability (HRV indicates how heart rate changes in response to inner and external stimuli. HRV is linked to health status and it is an indirect marker of the autonomic nervous system (ANS function. Objective: To investigate the influence of osteopathic manipulative treatment (OMT on ANS activity through changes of High Frequency, a heart rate variability index indicating the parasympathetic activity, in healthy subjects, compared with sham therapy and control group.Methods: Sixty-six healthy subjects, both male and female, were included in the present 3-armed randomized placebo controlled within subject cross-over single blinded study. Participants were asymptomatic adults, both smokers and non-smokers and not on medications. At enrollment subjects were randomized in 3 groups: A, B, C. Standardized structural evaluation followed by a patient need-based osteopathic treatment was performed in the first session of group A and in the second session of group B. Standardized evaluation followed by a protocoled sham treatment was provided in the second session of group A and in the first session of group B. No intervention was performed in the two sessions of group C, acting as a time-control. The trial was registered on clinicaltrials.gov identifier: NCT01908920.Main Outcomes Measures: HRV was calculated from electrocardiography before, during and after the intervention, for a total amount time of 25 minutes.Results: OMT engendered a statistically significant increase of parasympathetic activity, as shown by High Frequency rate (p<0.001, and decrease of sympathetic activity, as revealed by Low Frequency rate (p<0.01; results also showed a reduction of Low Frequency/High Frequency ratio (p<0.001 and Detrended fluctuation scaling exponent (p<0.05. Conclusions: Findings suggested that OMT can influence ANS activity increasing parasympathetic function and decreasing sympathetic activity, compared to sham therapy and control group.

    Acid-base functional groups at the surface of Anoxybacillus flavithermus (AF) were assigned from the modeling of batch titration data of bacterial suspensions and compared with those determined from in situ infrared spectroscopic titration analysis. The computer program FITMOD was used to generate a two-site Donnan model (site 1: pKa = 3.26, wet concn = 2.46 x 10(-4) mol g(-1); site 2: pKa = 6.12, wet concn = 6.55 x 10(-5) mol g(-1)), which was able to describe data for whole exponential phase cells from both batch acid-base titrations at 0.01 M ionic strength and electrophoretic mobility measurements over a range of different pH values and ionic strengths. In agreement with information on the composition of bacterial cell walls and a considerable body of modeling literature, site 1 of the model was assigned to carboxyl groups, and site 2 was assigned to amino groups. pH difference IR spectra acquired by in situ attenuated total reflection infrared (ATR-IR) spectroscopy confirmed the presence of carboxyl groups. The spectra appear to show a carboxyl pKa in the 3.3-4.0 range. Further peaks were assigned to phosphodiester groups, which deprotonated at slightly lower pH. The presence of amino groups could not be confirmed or discounted by IR spectroscopy, but a positively charged group corresponding to site 2 was implicated by electrophoretic mobility data. Carboxyl group speciation over a pH range of 2.3-10.3 at two different ionic strengths was further compared to modeling predictions. While model predictions were strongly influenced by the ionic strength change, pH difference IR data showed no significant change. This meant that modeling predictions agreed reasonably well with the IR data for 0.5 M ionic strength but not for 0.01 M ionic strength.

Risk groups were defined and the prevalence of new TB cases in each group calculated. Costs of each screening component were used to give indicative costs per case detected. Yield, number needed to screen (NNS and cost per case were used to assess the algorithms.The prevalence survey identified 172 new TB cases in 34,250 participants. Prevalence varied greatly in different groups, from 131/100,000 to 4651/ 100,000. Two groups were chosen to compare the algorithms. The medium-risk group (living in a rural area: men, or previous TB case, or close contact or a BMI <18.5, or tobacco user had appreciably higher cost per case (USD 221, 298 and 963 in the three algorithms than the high-risk group (all previous TB cases, all close contacts.

Using a Chest x-ray as the initial screening tool in the medium risk group cost the most (USD 963, and detected 67% of all the new cases. Using the NTP definition of TB suspects made little difference.To "End TB", many more TB cases have to be identified. Screening only the highest risk groups identified under 14% of the undetected cases,. To "End TB", medium risk groups will need to be screened. Using a CXR for initial screening results in a much higher yield, at what should be an acceptable cost.

    Communicating information about disease-modifying anti-rheumatic drugs (DMARDs) before patients start treatment is a key role for some rheumatology clinical nurse specialists. This is done in our unit to promote understanding of the risks and benefits of drug therapy and encourage timely and reliable use of DMARDs. Information is routinely provided individually but this can lead to delays in starting treatment because of limited nursing resources. In this randomized trial we tested the feasibility of giving patients, who were about to start on a DMARD, information about the drug in groups and compared this with information given individually. Adults with a clinical diagnosis of rheumatoid arthritis or psoriatic arthritis who were referred to the nursing team for counselling about starting on methotrexate, sulfasalazine or leflunomide were included. Patients who had previously taken a DMARD were not excluded and those consenting were randomized to receive drug information individually or in groups (of three to six patients). We provided all patients with written materials about the relevant drug and discussed the risks and benefits of drug use verbally. Patients allocated to group counselling received this intervention in a teaching room, with a slide presentation. The primary outcome was adherence with medication use, ascertained by pill counts, self-report diaries and prescription dispensation. Secondary outcomes included satisfaction with information about medicines (SIMS) by questionnaire; time taken to provide information; adherence to scheduled hospital appointments and blood monitoring schedules; and DMARD continuation rates at four and twelve months. Of 127 eligible patients referred for counselling about DMARDs, 62 consented to take part: 32 were randomized to receive drug information individually and 30 to receiving it in groups. Patients allocated to the two different interventions were comparable for age and diagnoses at baseline but more patients

    Children and adolescents with psychogenic non-epileptic seizures (PNES) and epilepsy are known to have psychosocial problems. The aim of the present study was to compare the psychosocial difficulties, history of stressful life events/abuse, psychiatric diagnosis, and self-esteem of adolescents with PNES to the ones with epilepsy and healthy controls at a tertiary care center in Turkey. Thirty-four adolescents with PNES diagnosed by video-EEG were compared with 23 adolescents that have epilepsy and 35 healthy volunteers. Comorbid psychiatric diagnoses of participants were examined by semi-structured interviews using Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version (KSADS-PL). Self-esteem of adolescents was evaluated by Rosenberg Self Esteem Scale (RSES). No differences in sociodemographic features were observed between the groups. The PNES group showed significantly higher rates of parental conflicts, difficulties in relationship with siblings/peers, school under-achievement, and history of stressful events/abuse. The rates of comorbid psychiatric disorders were 64.7% in PNES and 47.8% in epilepsy group. The most common disorders in both groups were attention deficit hyperactivity disorder (ADHD) and depressive disorder. The rate of posttraumatic stress disorder (PTSD) was significantly increased in the PNES group. Additionally, adolescents with PNES displayed significantly lower levels of self-esteem than the other groups. It could be concluded that both disorders involved a high risk for developing psychiatric disorders; additionally, adolescents with PNES have higher rates of stressors and lower levels of self-esteem. Findings from this investigation point to the importance of psychiatric interventions in pediatric PNES and also epilepsy.

    To test, in this pilot study, whether DHEA-S (Dehydroepiandrosterone, sulfated form) plasma levels are lower among persons with chronic neck pain, compared to control persons, and to investigate the DHEA-S response after a physical exercise. Included were 12 persons with chronic neck pain and eight controls without present pain, all 18 and 65 years of age. Exclusion criteria for both groups were articular diseases or tendinosis, fibromyalgia, systemic inflammatory and neuromuscular diseases, pain conditions due to trauma, or severe psychiatric diseases. The participants arm-cycled on an ergometer for 30 minutes. Blood samples were taken before, 60 minutes, and 150 minutes after this standardized physical exercise. The estimated plasma DHEA-S levels at baseline were 2.0 µmol/L (95% confidence interval [CI] 1.00; 4.01) in the pain group and 4.1 µmol/L (95% CI2.0; 8.6) in the control group, adjusted for sex, age, body mass index (BMI), and Shirom-Melamed Burnout Questionnaire (SMBQ), with a ratio of 0.48 ( P  = 0.094). In this pilot study, the plasma DHEA-S levels appeared to be lower among the persons with chronic neck pain, compared with the control group. It was indicated that DHEA-S decreased during the physical exercise in the control group, and either increased or was unaffected in the chronic pain group. © 2016 American Academy of Pain Medicine.

    To assess how upper limb amputation affects mental health and life satisfaction. Cross-sectional study comparing the mental health and perceived satisfaction with life among adult acquired major upper limb amputees in Norway with a control group drawn from the Norwegian general population. The scales used were the Satisfaction With Life Scale (SWLS) and the Hopkins Symptom Check List 25-item (SCL-25). The groups were compared using multiple linear regression analyses. The amputees scored significantly lower on life satisfaction than the control group. A tendency to poorer mental health in the amputee group was observed, but there was no clear evidence of such a difference. The amputation effect on life satisfaction seemed to be mediated mainly by changes in occupational status and by the occurrence of short- or long-term complications related to the amputation. Our findings imply that rehabilitation of upper limb amputees should emphasise facilitating return to work as well as the prevention of short- and long-term complications, and that this will be of importance not only for the amputees' physical function, but for the maintenance of acceptable life satisfaction. Further studies on the effect of upper limb amputation on mental health are recommended.

    Panic disorder refers to the frequent and recurring acute attacks of anxiety. Objective: This study describes the routine use of mobiles phones (MPs) and investigates the appearance of possible emotional alterations or symptoms related to their use in patients with panic disorder (PD). Background: We compared patients with PD and agoraphobia being treated at the Panic and Respiration Laboratory of The Institute of Psychiatry, Federal University of Rio de Janeiro, Brazil, to a control group of healthy volunteers. Methods: An MP-use questionnaire was administered to a consecutive sample of 50 patients and 70 controls. Results: People with PD showed significant increases in anxiety, tachycardia, respiratory alterations, trembling, perspiration, panic, fear and depression related to the lack of an MP compared to the control group. Conclusions: Both groups exhibited dependence on and were comforted by having an MP; however, people with PD and agoraphobia showed significantly more emotional alterations as well as intense physical and psychological symptoms when they were apart from or unable to use an MP compared to healthy volunteers.

    Background In Traditional Chinese Medicine (TCM) theory, functional dyspepsia (FD) can be divided into different syndromes according to different clinical symptoms and signs, and the most common one is spleen-deficiency and qi-stagnation syndrome that can be treated by Chinese traditional patent medicine ---- two kinds of Zhizhu pills, between which the primary difference in ingredients is that one contains immature orange fruit of Citrus aurantium L.(IFCA) and the other contains that of Citrus sinensis Osbeck (IFCS). The trial's objective was to compare the efficacy of two kinds of Zhizhu pills on symptom changes in patients with FD of spleen-deficiency and qi-stagnation syndrome. Methods A randomized, group sequential, double-blinded, multicenter trial was conducted in patients with FD of spleen-deficiency and qi-stagnation syndrome at 3 hospitals in Beijing between June 2003 and May 2005. Participants were randomly allocated into two groups (IFCA group and IFCS group) in a 1:1 ratio, and respectively took one of the two kinds of Zhizhu pills orally, 6 g each time, 3 times a day, for 4 weeks. Statistical analysis was performed with use of a group sequential method, the triangular test (TT). Results A total of 163 patients were randomized, and 3 patients were excluded from analysis because of early dropouts, leaving 160 patients (IFCA group: n = 82; IFCS group: n = 78) for statistical analysis. Three interim analyses were done after 62, 116, and 160 patients had completed their 4-week treatment, respectively. At the third interim analysis, the sample path crossed the upper boundary and the trial was stopped, the cure-markedly effective rates were 45% for IFCS group and 67% for IFCA group, respectively, the one-sided p-value was 0.0036, the median unbiased estimate of the odds ratio (OR) for the benefit of IFCA relative to IFCS was 2.91 with 95%CI: 1.40 to 6.06. No adverse events were observed in the two groups. Conclusions Zhizhu pills containing IFCA was superior

    Mass breast cancer screening is offered to French women between the ages of 50 and 74. In the French overseas department of Guadeloupe, where the population is of mostly African ancestry, a low age at diagnosis of breast cancer has been reported, as for African-Americans. This raises the question of whether breast cancer is more aggressive in the age group preceding that eligible for mass screening (40-49) in Guadeloupe. We compared the tumor-related prognostic factors, first line therapy and overall survival rates of breast cancer cases diagnosed between the 40-49 and 50-74 age groups, based on reports of the cancer registry of Guadeloupe for the period 2008-2013. The characteristics studied, risk of death after breast cancer (HR 0.84 [95% CI: 0.58-1.22] and overall survival, did not differ significantly between the two groups, except for higher tumor size (28.8 vs 24.0; p=0.004) in the younger group. These results do not show a pattern of more aggressive breast cancer in the age group preceding that eligible for mass screening in Guadeloupe. Copyright © 2017 Elsevier Ltd. All rights reserved.

    There is limited amount of data available on the comparative efficacy of ibrutinib and idelalisib, the B-cell receptor inhibitors (BCRi) newly approved for relapsed/refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (r/r CLL/SLL) treatment. The aim of our study was to analyze and compare the outcomes of real-world r/r CLL/SLL patients treated with these two BCRi in outside clinical trials. A comparative case matched 1:2 analysis was performed on idelalisib combined with rituximab and ibrutinib efficacy in 102 patients with r/r CLL/SLL from two observational studies of the Polish Adult Leukemia Group (PALG). Both therapies produced similar overall response rates (idelalisib plus rituximab 76.4% and ibrutinib 72.1%). Median progression-free survival (PFS) and overall survival (OS) in both groups were not reached. Furthermore, no significant difference was observed between both BCRi regimens in regard to PFS (HR=0.75, 95% CI=0.30-1.86, p=0.55) and OS (HR=0.65, 95%CI=0.26-1.68, p=0.39). In summary, the results of this retrospective analysis suggest that idelalisib combined with rituximab and ibrutinib therapies have comparable activity in r/r CLL/SLL in daily clinical practice.

    Training the health personnel about domestic violence would cause them to investigate and evaluate this issue more than before. Considering the new educational approaches for transferring knowledge, the goal of this research was to compare the effect of group-based and compact disk (CD)-based training on midwives' knowledge and attitude toward domestic violence. In this clinical experiment, seventy midwives working at health centers and hospitals of Isfahan were randomly allocated into two classes of group-based and CD-based trainings and were trained in the fields of recognition, prevention, and management of domestic violence. Data were collected by questionnaires which were completed by the midwives for evaluation of their knowledge and attitude. The mean score of midwives' knowledge and attitude toward domestic violence had a meaningful increase after the training (16.1, 46.9) compared to the score of before the training (12.1, 39.1) in both of the classes (group-based training: 17.7, 45.4) (CD-based training: 11.7, 38.6). No meaningful difference was observed between the two groups regarding midwives' attitude toward domestic violence after the intervention; however, regarding their knowledge level, the difference was statistically meaningful ( P = 0.001), and this knowledge increase was more in the CD-based training group. In spite of the effectiveness of both of the training methods in promoting midwives' knowledge and attitude about domestic violence, training with CD was more effective in increasing their knowledge; as a result, considering the benefits of CD-based training such as cost-effectiveness and possibility of use at any time, it is advised to be used in training programs for the health personnel.

    Full Text Available Background Atherosclerosis is the main cause of cardiovascular diseases, and its risk enhances in type 2 diabetes mellitus. Objectives This study aimed to evaluate Carotid Intima-Media Thickness (CIMT by carotid artery ultrasonography and assess its correlation with microalbuminuria and estimated Glomerular Filtration Rate (eGFR in the patients with type 2 diabetes mellitus. Patients and Methods This cross-sectional study was included 205 patients with Type 2 Diabetes Mellitus (T2DM. We recorded clinical and biochemical data such as FBS, lipid profile, and urinary albumin. Intima-media thickness of carotid arteries was measured in all patients by high frequency ultrasound. Results In simple correlation coefficients analysis, CIMT was significantly associated with total cholesterol (r = 0.197, P = 0.008, serum creatinine (r = 0.240, P = 0.001, and urinary albumin (r = 0.420, P = 0.000. Also, CIMT elevated significantly with the stage progression of chronic kidney disease (0.67 ± 0.15 mm in stage 1, 0.73 ± 0.22 mm in stage 2, and 0.82 ± 0.21 mm in stage 3 (P value = 0.024. In multivariate linear regression analysis, the duration of diabetes, weight, HDL, serum creatinine, urinary albumin, and estimated Glomerular Filtration Rate (eGFR were independently associated with CIMT (P value < 0.05 for all. Conclusions Our study shows a relationship between CIMT and renal parameters, including eGFR and albuminuria. This study confirms the importance of intensive examinations for early detection of atherosclerosis and treatment of risk factors.

    Full Text Available Diabetes mellitus (DM is now considered as the major cause of end-stage kidney failure, and hypertension (HTN is one of the main determinants of progression of renal disease. The aim of this study was to assess the role of blood pressure (BP by ambulatory blood pressure monitoring (ABPM in children and adolescents with type-1 DM and its correlation with micro-albuminuria (MA and diabetic control. Eighty-one patients with type-1 DM (mean age 13 ± 4 years, whose duration of DM was at least two years, were enrolled in this study. The prevalence of HTN based on ABPM was 28.4%, while by casual method it was 32.1%. The pattern of HTN was as follows: mean systolic HTN 27.2%, mean diastolic HTN 11.2%, daytime systolic HTN 17.3%, daytime diastolic HTN 6.2%, night systolic HTN 30.9%, and night diastolic HTN 29.7%. The systolic and diastolic BP loads were 33.4 and 27.2%, respectively. About 70.4% of the patients were non-dippers, 12.4% had masked HTN, and 3.7% had white coat HTN. The pre-valence of MA was 34.6% and that of abnormal HbA 1 c was 82.7%. There was no correlation bet-ween HTN and both MA and HbA 1 c; also, no correlation was found between the duration of dia-betes and HbA 1 c. Moreover, no significant correlation was found between the duration of diabetes and MA (P = 0.080. Despite the high prevalence of abnormal BP profile among diabetic children, prospective longitudinal studies considering the other major risk factors, particularly genetic factors, which have an impact on the progression to diabetic nephropathy, are recommended.

    Increasingly, Web-based health applications are developed for the prevention and management of chronic diseases. However, their reach and utilization is often disappointing. Qualitative evaluations post-implementation can be used to inform the optimization process and ultimately enhance their adoption. In current practice, such evaluations are mainly performed with end-user surveys. However, a review approach by experts in a focus group may be easier to administer and might provide similar results. The aim of this study was to assess whether industrial design engineers in a focus group would address the same issues as end users in a Web-based survey when evaluating a commercial Web-based health risk assessment (HRA) with tailored feedback. Seven Dutch companies used the HRA as part of their corporate health management strategy. Employees using the HRA (N=2289) and 10 independent industrial designers were invited to participate in the study. The HRA consisted of four components: (1) an electronic health questionnaire, (2) biometric measurements, (3) laboratory evaluation, and (4) individually tailored feedback generated by decision support software. After participating in the HRA as end users, both end users and designers evaluated the program. End users completed an evaluation questionnaire that included a free-text field. Designers participated in a focus group discussion. Constructs from user satisfaction and technology acceptance theories were used to categorize and compare the remarks from both evaluations. We assessed and qualitatively analyzed 294 remarks of 189 end users and 337 remarks of 6 industrial designers, pertaining to 295 issues in total. Of those, 137 issues were addressed in the end-user survey and 148 issues in the designer focus group. Only 7.3% (10/137) of the issues addressed in the survey were also addressed in the focus group. End users made more remarks about the usefulness of the HRA and prior expectations that were not met. Designers made

    We compare the prevalence of suicidal thoughts and attempts between Indigenous and non-Indigenous males in urban and regional Australia, and examine the extent to which any disparity between Indigenous and non-Indigenous males varies across age groups. We used data from the baseline wave of The Australian Longitudinal Study on Male Health (Ten to Men), a large-scale cohort study of Australian males aged 10-55 years residing in urban and regional areas. Indigenous identification was determined through participants self-reporting as Aboriginal, Torres Strait Islander or both. The survey collected data on suicidal thoughts in the preceding 2 weeks and lifetime suicide attempts. A total of 432 participants (2.7%) identified as Indigenous and 15,425 as non-Indigenous (97.3%). Indigenous males were twice as likely as non-Indigenous males to report recent suicidal thoughts (17.6% vs 9.4%; odds ratio = 2.1, p age groups, but a significant gap emerged among men aged 30-39 years and was largest among men aged 40-55 years. Similarly, the prevalence of lifetime suicide attempts did not differ between Indigenous and non-Indigenous males in the 14- to 17-years age group, but a disparity emerged in the 18- to 24-years age group and was even larger among males aged 25 years and older. Our paper presents unique data on suicidal thoughts and attempts among a broad age range of Indigenous and non-Indigenous males. The disparity in the prevalence of suicidal thoughts increased across age groups, which is in contrast to the large disparity between the Indigenous and non-Indigenous suicide rates in younger age groups.

    Full Text Available Background: Incidences of side effects and relapses are very common in chronic ulcerative colitis patients after termination of the treatment. Aims and Objectives: This study aims to compare the treatment with monoherbal formulation of Holarrhena antidysenterica with Mesalamine in chronic ulcerative colitis patients with special emphasis to side effects and relapse. Settings and Design: Patients were enrolled from an Ayurveda Hospital and a private Hospital, Gujarat. The study was randomized, parallel group and single blind design. Materials and Methods: The protocol was approved by Institutional Human Research Ethics Committee of Anand Pharmacy College on 23rd Jan 2013. Three groups (n = 10 were treated with drug Mesalamine (Group I, monoherbal tablet (Group II and combination of both (Group III respectively. Baseline characteristics, factors affecting quality of life, chronicity of disease, signs and symptoms, body weight and laboratory investigations were recorded. Side effects and complications developed, if any were recorded during and after the study. Statistical Analysis Used: Results were expressed as mean ± SEM. Data was statistically evaluated using t-test, Wilcoxon test, Mann Whitney U test, Kruskal Wallis test and ANOVA, wherever applicable, using GraphPad Prism 6. Results: All the groups responded positively to the treatments. All the patients were positive for occult blood in stool which reversed significantly after treatment along with rise in hemoglobin. Patients treated with herbal tablets alone showed maximal reduction in abdominal pain, diarrhea, and bowel frequency and stool consistency scores than Mesalamine treated patients. Treatment with herbal tablet alone and in combination with Mesalamine significantly reduced the stool infection. Patients treated with herbal drug alone and in combination did not report any side effects, relapse or complications while 50% patients treated with Mesalamine exhibited the relapse with

    The difference in diabetes susceptibility by ethnic background is poorly understood. The aim of this study was to assess the association between adiposity and diabetes in four ethnic minority groups compared with Norwegians, and take into account confounding by socioeconomic position. Data from questionnaires, physical examinations and serum samples were analysed for 30-to 60-year-olds from population-based cross-sectional surveys of Norwegians and four immigrant groups, comprising 4110 subjects born in Norway (n = 1871), Turkey (n = 387), Vietnam (n = 553), Sri Lanka (n = 879) and Pakistan (n = 420). Known and screening-detected diabetes cases were identified. The adiposity measures BMI, waist circumference and waist-hip ratio (WHR) were categorized into levels of adiposity. Gender-specific logistic regression models were applied to estimate the risk of diabetes for the ethnic minority groups adjusted for adiposity and income-generating work, years of education and body height used as a proxy for childhood socioeconomic position. The age standardized diabetes prevalence differed significantly between the ethnic groups (women/men): Pakistan: 26.4% (95% CI 20.1-32.7)/20.0% (14.9-25.2); Sri Lanka: 22.5% (18.1-26.9)/20.7% (17.3-24.2), Turkey: 11.9% (7.2-16.7)/12.0% (7.6-16.4), Vietnam: 8.1% (5.1-11.2)/10.4% (6.6-14.1) and Norway: 2.7% (1.8-3.7)/6.4% (4.6-8.1). The prevalence increased more in the minority groups than in Norwegians with increasing levels of BMI, WHR and waist circumference, and most for women. Highly significant ethnic differences in the age-standardized prevalence of diabetes were found for both genders in all categories of all adiposity measures (p minority groups in Oslo, with those from Sri Lanka and Pakistan at highest risk. For all levels of adiposity, a higher susceptibility for diabetes was observed for ethnic minority groups compared with Norwegians. The association persisted after adjustment for socioeconomic position for all minority women

    Group exercise programs for older adults often exclude the timing and coordination of movement. Stakeholder involvement in the research process is strongly encouraged and improves the relevance and adoption of findings. We describe stakeholder involvement in the design of a clinical trial of a group-based exercise program that incorporates timing and coordination of movement into the exercises. The study was a cluster randomized, single-blind intervention trial to compare the effects on function, disability and mobility of a standard group exercise program and the "On the Move" group exercise program in older adults residing in independent living facilities and senior apartment buildings, and attending community centers. Exercise classes were twice weekly for 12weeks delivered by study exercise leaders and facility activity staff personnel. The primary outcomes function, disability and mobility were assessed at baseline and post-intervention. Function and disability were assessed using the Late Life Function and Disability Instrument, and mobility using the Six-Minute Walk Test and gait speed. Patient and provider stakeholders had significant input into the study aims, design, sample, intervention, outcomes and operational considerations. A community-based exercise program to improve walking can be developed to address both investigator identified missing components in current exercise to improve walking and stakeholder defined needs and interest for the activity program. Involvement of stakeholders substantially improves the relevance of research questions, increases the transparency of research activities and may accelerate the adoption of research into practice.

    Dental caries is one of the most common health problems in the world. Probiotics are one the various preventive methods to reduce dental caries. The aim of this study is to compare the effectiveness of probiotic ice cream and drink on salivary Streptococcus mutans levels in children of 6-12 years age group. A three phase study was carried out in children (n = 50) of 6-12 years age with zero decayed missing filled teeth (dmft)/DMFT. They were randomly divided into two equal groups. Saliva samples were collected before the consumptions of probiotic ice cream and probiotic drink. Colony count obtained was recorded as baseline data. For both groups probiotic ice cream and drink was given randomly for 7 days and a washout period of 90 days were given and then the saliva samples were collected and colony counting was done. Statistical analysis was performed using Student's paired t-test and multiple comparisons by Tukey's honest significant difference test which showed, there is a significant reduction in salivary S. mutans level in both groups after 7 days period. However, after washout period only probiotic ice cream showed reduction whereas drink did not. Also, there was no significant difference between probiotic ice cream and drink. Probiotic organisms definitely have a role in reducing the salivary S. mutans level and ice cream would be a better choice than drink. However, the prolonged use of the agents and their effects on caries is still to be determined.

    To investigate the effectiveness of a patient education (PE) program with or without the added effect of manual therapy (MT) compared to a minimal control intervention (MCI). In a single-center university hospital setting, a total of 118 patients with clinical and radiographic unilateral hip osteoarthritis (OA) from primary care were randomized into one of three groups: PE, PE plus MT or MCI. The PE was taught by a physiotherapist involving five sessions. The MT was delivered by a chiropractor involving 12 sessions and the MCI included a home stretching program. Primary outcome was self-reported pain severity on an 11-box numeric rating scale (NRS) immediately following a 6-week intervention period. Patients were followed for 1 year. Primary analysis included 111 patients (94%). In the combined group (PE + MT), a clinically relevant reduction in pain severity compared to the MCI of 1.90 points (95% confidence interval (CI) 0.9-2.9) was achieved. Effect size (Cohen's d) for the PE + MT minus the MCI was 0.92 (95% CI 0.41-1.42). Number needed to treat for PE + MT was 3 (95% CI 2-7). No difference was found between the PE and MCI groups, with mean difference 0.0 (95% CI -1.0 to 1.0). At 12 months, not including patients receiving hip surgery the statistically significant difference favoring PE + MT was maintained. For primary care patients with OA of the hip, a combined intervention of MT and PE was more effective than a MCI. PE alone was not superior to the MCI. clinicaltrials.govNCT01039337.

    Obesity is a risk factor for breast cancer recurrence and death. Women who reside in rural areas have higher obesity prevalence and suffer from breast cancer treatment-related disparities compared to urban women. The objective of this 5-year randomized controlled trial is to compare methods for delivering extended care for weight loss maintenance among rural breast cancer survivors. Group phone-based counseling via conference calls addresses access barriers, is more cost-effective than individual phone counseling, and provides group support which may be ideal for rural breast cancer survivors who are more likely to have unmet support needs. Women (n=210) diagnosed with Stage 0 to III breast cancer in the past 10 years who are ≥ 3 months out from initial cancer treatments, have a BMI 27-45 kg/m(2), and have physician clearance were enrolled from multiple cancer centers. During Phase I (months 0 to 6), all women receive a behavioral weight loss intervention delivered through group phone sessions. Women who successfully lose 5% of weight enter Phase II (months 6 to 18) and are randomized to one of two extended care arms: continued group phone-based treatment or a mail-based newsletter. During Phase III, no contact is made (months 18 to 24). The primary outcome is weight loss maintenance from 6 to 18 months. Secondary outcomes include quality of life, serum biomarkers, and cost-effectiveness. This study will provide essential information on how to reach rural survivors in future efforts to establish weight loss support for breast cancer survivors as a standard of care.

    There is little consensus on the most efficacious vehicle substance for vitamin D supplements. Fat malabsorption may impede the ability of patients with cystic fibrosis (CF) to absorb vitamin D in an oil vehicle. We hypothesized that vitamin D contained in a powder vehicle would be absorbed more efficiently than vitamin D contained in an oil vehicle in patients with CF. In this double-blind, randomized controlled trial, hospitalized adults with CF were given a one-time bolus dose of 100,000 IU of cholecalciferol (D 3 ) in a powder-based or oil-based vehicle. Serum D 3 , 25-hydroxyvitamin D, and parathyroid hormone concentrations were analyzed at 0, 12, 24, and 48 hours posttreatment. The area under the curve for serum D 3 and the 12-hour time point were also assessed as indicators of D 3 absorption. This trial was completed by 15 patients with CF. The median (interquartile range) age, body mass index, and forced expiratory volume in 1 second were 23.7 (19.9-33.2) years, 19.9 (18.6-22.6) kg/m 2 , and 63% (37%-80%), respectively. The increase in serum D 3 and the area under the curve was greater in the powder group ( P = .002 and P = .036, respectively). Serum D 3 was higher at 12 hours in the powder group compared with the oil group ( P = .002), although levels were similar between groups by 48 hours. In adults with CF, cholecalciferol is more efficiently absorbed in a powder compared with an oil vehicle. Physicians should consider prescribing vitamin D in a powder vehicle in patients with CF to improve the absorption of vitamin D from supplements.

    Background Delays in abnormal mammogram follow-up contribute to poor outcomes. We examined abnormal screening mammogram follow-up differences for non-Hispanic Whites (NHW) and Asian women. Methods Prospective cohort of NHW and Asian women with a Breast Imaging Reporting and Data System abnormal result of 0 or 3+ in the San Francisco Mammography Registry between 2000–2010. We performed Kaplan-Meier estimation for median-days to follow-up with a diagnostic radiologic test, and compared proportion with follow-up at 30, 60 and 90 days, and no follow-up at one-year for Asians overall (and Asian ethnic groups) and NHWs. We additionally assessed the relationship between race/ethnicity and time-to-follow-up with adjusted Cox proportional hazards models. Results Among Asian women, Vietnamese and Filipinas had the longest, and Japanese the shortest, median follow-up time (32, 28, 19 days, respectively) compared to NHWs (15 days). The proportion of women receiving follow-up at 30 days was lower for Asians vs NHWs (57% vs 77%, pAsian ethnic groups except Japanese. Asians had a reduced hazard of follow-up compared with NHWs (aHR 0.70, 95% CI 0.69–0.72). Asians also had a higher rate than NHWs of no follow-up (15% vs 10%; pAsian ethnic groups, Filipinas had the highest percentage of women with no follow-up (18.1%). Conclusion Asian, particularly Filipina and Vietnamese, women were less likely than NHWs to receive timely follow-up after an abnormal screening mammogram. Research should disaggregate Asian ethnicity to better understand and address barriers to effective cancer prevention. PMID:28603859

    Ethnic minority populations in Western societies suffer from a disproportionate burden of type 2 diabetes (T2D). Insight into the role of dietary patterns in T2D may assist public health nutrition efforts in addressing these health disparities. We explored the association between dietary patterns and biomarkers of T2D in 5 ethnic groups living in Amsterdam, Netherlands. A total of 3776 men and women aged 18-70 y of Dutch, South Asian Surinamese, African-Surinamese, Turkish, and Moroccan origin from the HELIUS (HEalthy LIfe in an Urban Setting) study were included. Diet was assessed by using a food-frequency questionnaire, and dietary patterns were derived separately per ethnic group. First, food group-based dietary patterns were derived by using principal components analysis and the association with glycated hemoglobin (HbA1c) and plasma fasting glucose was assessed by using multivariable linear regression. Second, biomarker-driven dietary patterns based on HbA1c and fasting glucose concentrations were derived by applying reduced rank regression. Two comparable food group-based dietary patterns were identified in each ethnic group: a "meat and snack" pattern and a "vegetable" pattern. The meat-and-snack pattern derived within the Dutch origin population was significantly associated with HbA1c (β = 0.09; 95% CI: 0.00, 0.19) and fasting glucose (β = 0.18; 95% CI: 0.09, 0.26) concentrations. A biomarker-derived pattern characterized by red and processed meat was observed among Dutch-origin participants; however, among ethnic minority groups, this pattern was characterized by other foods including ethnicity-specific foods (e.g., roti, couscous). Although similar food group dietary patterns were derived within 5 ethnic groups, the association of the meat-and-snack pattern with fasting glucose concentrations differed by ethnicity. Taken together with the finding of ethnic differences in biomarker-driven dietary patterns, our results imply that addressing T2D risk in

    PURPOSE. This study compares a traditional worksite-based health promotion program with an activated consumer program and a control program DESIGN. Group randomized controlled trial with 18-month intervention. SETTING. Two large Midwestern companies. SUBJECTS. Three hundred and twenty employees (51% response). INTERVENTION. The traditional health promotion intervention offered population-level campaigns on physical activity, nutrition, and stress management. The activated consumer intervention included population-level campaigns for evaluating health information, choosing a health benefits plan, and understanding the risks of not taking medications as prescribed. The personal development intervention (control group) offered information on hobbies. The interventions also offered individual-level coaching for high risk individuals in both active intervention groups. MEASURES. Health risk status, general health status, consumer activation, productivity, and the ability to evaluate health information. ANALYSIS. Multivariate analyses controlled for baseline differences among the study groups. RESULTS. At the population level, compared with baseline performance, the traditional health promotion intervention improved health risk status, consumer activation, and the ability to recognize reliable health websites. Compared with baseline performance, the activated consumer intervention improved consumer activation, productivity, and the ability to recognize reliable health websites. At the population level, however, only the activated consumer intervention improved any outcome more than the control group did; that outcome was consumer activation. At the individual level for high risk individuals, both traditional health coaching and activated consumer coaching positively affected health risk status and consumer activation. In addition, both coaching interventions improved participant ability to recognize a reliable health website. Consumer activation coaching also

    We examined type I and II error rates for analysis of (1) mean hospital length of stay (LOS) versus (2) percentage of hospital LOS that are overnight. These 2 end points are suitable for when LOS is treated as a secondary economic end point. We repeatedly resampled LOS for 5052 discharges of thoracoscopic wedge resections and lung lobectomy at 26 hospitals. Unequal variances t test (Welch method) and Fisher exact test both were conservative (ie, type I error rate less than nominal level). The Wilcoxon rank sum test was included as a comparator; the type I error rates did not differ from the nominal level of 0.05 or 0.01. Fisher exact test was more powerful than the unequal variances t test at detecting differences among hospitals; estimated odds ratio for obtaining P < .05 with Fisher exact test versus unequal variances t test = 1.94, with 95% confidence interval, 1.31-3.01. Fisher exact test and Wilcoxon-Mann-Whitney had comparable statistical power in terms of differentiating LOS between hospitals. For studies with LOS to be used as a secondary end point of economic interest, there is currently considerable interest in the planned analysis being for the percentage of patients suitable for ambulatory surgery (ie, hospital LOS equals 0 or 1 midnight). Our results show that there need not be a loss of statistical power when groups are compared using this binary end point, as compared with either Welch method or Wilcoxon rank sum test.

    Avoidance of excessive sedation and subsequent prolonged mechanical ventilation in intensive care units (ICUs) is recommended, but no data are available for critically ill postoperative patients. We hypothesised that in such patients stopping sedation immediately after admission to the ICU could reduce unnecessary sedation and improve patient outcomes. We did a randomised, parallel-group, clinical trial at three ICUs in France. Stratified randomisation with minimisation (1:1 via a restricted web platform) was used to assign eligible patients (aged ≥18 years, admitted to an ICU after abdominal surgery, and expected to require at least 12 h of mechanical ventilation because of a critical illness defined by a Sequential Organ Failure Assessment score >1 for any organ, but without severe acute respiratory distress syndrome or brain injury) to usual sedation care provided according to recommended practices (control group) or to immediate interruption of sedation (intervention group). The primary outcome was the time to successful extubation (defined as the time from randomisation to the time of extubation [or tracheotomy mask] for at least 48 h). All patients who underwent randomisation (except for those who were excluded after randomisation) were included in the intention-to-treat analysis. This study is registered with ClinicalTrials.gov, number NCT01486121. Between Dec 2, 2011, and Feb 27, 2014, 137 patients were randomly assigned to the control (n=68) or intervention groups (n=69). In the intention-to-treat analysis, time to successful extubation was significantly lower in the intervention group than in the control group (median 8 h [IQR 4-36] vs 50 h [29-93], group difference -33·6 h [95% CI -44·9 to -22·4]; p<0·0001). The adjusted hazard ratio was 5·2 (95% CI 3·1-8·8, p<0·0001). Immediate interruption of sedation in critically ill postoperative patients with organ dysfunction who were admitted to the ICU after abdominal surgery improved outcomes compared

    Data on the cardiovascular disease risk profiles of Pacific peoples in New Zealand is usually aggregated and treated as a single entity. Little is known about the comparability or otherwise of cardiovascular disease (CVD) risk between different Pacific groups. To compare CVD risk profiles for the main Pacific ethnic groups assessed in New Zealand primary care practice to determine if it is reasonable to aggregate these data, or if significant differences exist. A web-based clinical decision support system for CVD risk assessment and management (PREDICT) has been implemented in primary care practices in nine PHOs throughout Auckland and Northland since 2002, covering approximately 65% of the population of these regions. Between 2002 and January 2009, baseline CVD risk assessments were carried out on 11,642 patients aged 35-74 years identifying with one or more Pacific ethnic groups (4933 Samoans, 1724 Tongans, 1366 Cook Island Maori, 880 Niueans, 1341 Fijians and 1398 people identified as Other Pacific or Pacific Not Further Defined). Fijians were subsequently excluded from the analyses because of a probable misclassification error that appears to combine Fijian Indians with ethnic Fijians. Prevalences of smoking, diabetes and prior history of CVD, as well as mean total cholesterol/HDL ratio, systolic and diastolic blood pressures, and Framingham 5-year CVD risk were calculated for each Pacific group. Age-adjusted risk ratios and mean differences stratified by gender were calculated using Samoans as the reference group. Cook Island women were almost 60% more likely to smoke than Samoan women. While Tongan men had the highest proportion of smoking (29%) among Pacific men, Tongan women had the lowest smoking proportion (10%) among Pacific women. Tongan women and Niuean men and women had a higher burden of diabetes than other Pacific ethnic groups, which were 20-30% higher than their Samoan counterparts. Niuean men and women had lower blood pressure levels than all

    Full Text Available Abstract. Through this article we are offering a global view of a theory that explains and contributes to the understanding of the position of ethnic groups in the United States within the social hierarchy. This research is focused toward a comparative analysis of Mexican and Chinese groups starting considering the following Weberian statements: a one that considers the influence of ideas and religious beliefs in the economic behavior of individuals, b and, another one that conceives religions as ethical vehicles liable to inhibit or stimulate the process of social stratification. In sum, this deals trying to consider the influence of diverse elements of religious culture in the makeup of certain economic behavior and context which is capable of vitalizing or hindering group dynamism in the social scale. This behavior is remarkably related to: a money in all its modalities, savings, expenses, investments, loans, etc., b work and entrepreneur business, and c family and communitarian solidarity. We also would like to emphasize on problems stemming from the practical applications of theory and method to the above mentioned phenomenon, emphasizing the productivity of concepts and analytical categories which are representative of a Methodological Individualism and Rational General Theory.

    In recent years, graphene and its derivatives have become prominent subject matter due to their fascinating combination of properties and potential applications in a number application. While several fundamental studies have been progressed, there is a particular need to understand how different graphene derivatives are influenced in terms of their electrical and thermal conductivities by different functional groups they end up with through their manufacturing and functionalisation methods. This article addresses of the role of different functional groups present of different of reduced graphene oxides (rGO) concerning their electrical and thermal properties, and the results were compared with elemental analyses of functionalised reduced graphene oxide (frGO) and graphene. The results showed that electrical and thermal conductivities of the rGO samples, highly dependent on the presence of residual functional groups from oxidation, reduction and functionalisation processes. The increase in reduction of oxygen, hydroxyl, carboxylic, epoxide moieties and heterocyclic compounds increase the specific surface area of the samples through which the mean electron path has increased. This improved both electrical and thermal conductivities together in all the samples which were highly dependent on the efficiency of different reductant used in this study.

    Delays in abnormal mammogram follow-up contribute to poor outcomes. In the current study, the authors examined differences in abnormal screening mammogram follow-up between non-Hispanic white (NHW) and Asian women. The authors used a prospective cohort of NHW and Asian women with a Breast Imaging, Reporting and Data System (BI-RADS) abnormal result of category 0 or 3-plus in the San Francisco Mammography Registry between 2000 and 2010. Kaplan-Meier estimation for the median number of days to follow-up with a diagnostic radiologic test was performed, and the authors compared the percentage of women with follow-up at 30 days, 60 days, and 90 days and no follow-up at 1 year for Asian women overall (and Asian ethnic groups) and NHW women. In addition, the authors assessed the relationship between race/ethnicity and time to follow-up with adjusted Cox proportional hazards models. Among Asian women, Vietnamese and Filipina women had the longest, and Japanese women the shortest, median follow-up (32 days, 28 days, and 19 days, respectively) compared with NHW women (15 days). The percentage of women receiving follow-up at 30 days was lower for Asians versus NHWs (57% vs 77%; PAsian ethnic groups except Japanese. Asian women had a reduced hazard of follow-up compared with NHW women (adjusted hazard ratio, 0.70; 95% confidence interval, 0.69-0.72). Asian women also had a higher rate of receiving no follow-up compared with NHW women (15% vs 10%; PAsian ethnic groups, Filipinas were found to have the highest percentage of women with no follow-up (18.1%). Asian women, particularly Filipina and Vietnamese women, were less likely than NHW women to receive timely follow-up after an abnormal screening mammogram.

    The WRKY genes have been identified as important transcriptional modulators predominantly during the environmental stresses, but they also play critical role at various stages of plant life cycle. We report the identification of WRKY domain (WD)-encoding genes from galegoid clade legumes chickpea (Cicer arietinum L.) and barrel medic (Medicago truncatula). In total, 78 and 98 WD-encoding genes were found in chickpea and barrel medic, respectively. Comparative analysis suggests the presence of both conserved and unique WRKYs, and expansion of WRKY family in M. truncatula primarily by tandem duplication. Exclusively found in galegoid legumes, CaWRKY16 and its orthologues encode for a novel protein having a transmembrane and partial Exo70 domains flanking a group-III WD. Genomic region of galegoids, having CaWRKY16, is more dynamic when compared with millettioids. In onion cells, fused CaWRKY16-EYFP showed punctate fluorescent signals in cytoplasm. The chickpea WRKY group-III genes were further characterized for their transcript level modulation during pathogenic stress and treatments of abscisic acid, jasmonic acid, and salicylic acid (SA) by real-time PCR. Differential regulation of genes was observed during Ascochyta rabiei infection and SA treatment. Characterization of A. rabiei and SA inducible gene CaWRKY50 showed that it localizes to plant nucleus, binds to W-box, and have a C-terminal transactivation domain. Overexpression of CaWRKY50 in tobacco plants resulted in early flowering and senescence. The in-depth comparative account presented here for two legume WRKY genes will be of great utility in hastening functional characterization of crop legume WRKYs and will also help in characterization of Exo70Js. © The Author 2016.

    Global budget per calendar year is a traditional method of funding hospitals in Serbia. Diagnose related groups (DGR) is a method of hospital payment based on classification of patients into groups with clinically similar problems and similar utilization of hospital resources. The aim of this study was to compare current methods of hospital services payment with the projected costs by DRG payment method in urology. The data were obtained from the information system used in the Clinical Hospital Center "Dr. Dragiša Mišović"--Dedinje in Belgrade, Serbia. The implemented hospital information system was the main criterion for selection of healthcare institutions. The study included 994 randomly selected patients treated surgically and conservatively in 2012. Average costs under the current payment method were slightly higher than those projected by DRG, however, the variability was twice as high (54,111 ± 69,789 compared to 53,434 ± 32,509, p payment method as well as with the projected one by DRG was observed in relation to the number of days of hospitalization (ρ = 0.842, p payment system (β = 0.843, p payment system (β = 0.737, p payment method and the pro- jected DRG payment methods (β = 0.501, p Payment under the DRG system is administratively more complex because it requires detailed and standardized coding of diagnoses and procedures, as well as the information on the average consumption of resources (costs) per DRG. Given that aggregate costs of treatment under two hospital payment methods compared in the study are not significantly different, the focus on minor surgeries both under the current hospital payment method and under the introduced DRG system would be far more cost-effective for a hospital as great variations in treatment performance (reductions of days of hospitalization and complications), and consequently invoiced amounts would be reduced.

    This study compared the flow rate and pH of resting (unstimulated) and stimulated whole saliva before and after complete denture placement in different age groups. Fifty healthy, non-medicated edentulous individuals of different age groups requiring complete denture prostheses were selected from the outpatient department. The resting (unstimulated) and stimulated whole saliva and pH were measured at three stages i.e., i)Before complete denture placement;ii)Immediately after complete denture placement; andiii)After 2 to 3 months of complete denture placement. Saliva production was stimulated by chewing paraffin wax. pH was determined by using a digital pH meter. Statistically significant differences were seen in resting(unstimulated) and stimulated whole salivary flow rate and pH obtained before, immediately after, and after 2 to 3 months of complete denture placement. No statistically significant differences were found between the different age groups in resting (unstimulated) as well as stimulated whole salivary flow rate and pH. Stimulated whole salivary flow rates and pH were significantly higher than resting (unstimulated) whole salivary flow rates and pH obtained before, immediately after, and after 2 to 3 months of complete denture placement. No age related variations in whole salivary flow rate and pH were observed in healthy, non-medicated individuals. The assessment of salivary flow rate, pH in different age groups is of prognostic value, which is an important aspect to be considered in the practice of removable prosthodontics.

    Although the HKT transporter genes ascertain some of the key determinants of crop salt tolerance mechanisms, the diversity and functional role of group II HKT genes are not clearly understood in bread wheat. The advanced knowledge on rice HKT and whole genome sequence was, therefore, used in comparative gene analysis to identify orthologous wheat group II HKT genes and their role in trait variation under different saline environments. The four group II HKTs in rice identified two orthologous gene families from bread wheat, including the known TaHKT2;1 gene family and a new distinctly different gene family designated as TaHKT2;2. A single copy of TaHKT2;2 was found on each homeologous chromosome arm 7AL, 7BL and 7DL and each gene was expressed in leaf blade, sheath and root tissues under non-stressed and at 200 mM salt stressed conditions. The proteins encoded by genes of the TaHKT2;2 family revealed more than 93% amino acid sequence identity but ≤52% amino acid identity compared to the proteins encoded by TaHKT2;1 family. Specifically, variations in known critical domains predicted functional differences between the two protein families. Similar to orthologous rice genes on chromosome 6L, TaHKT2;1 and TaHKT2;2 genes were located approximately 3 kb apart on wheat chromosomes 7AL, 7BL and 7DL, forming a static syntenic block in the two species. The chromosomal region on 7AL containing TaHKT2;1 7AL-1 co-located with QTL for shoot Na(+) concentration and yield in some saline environments. The differences in copy number, genes sequences and encoded proteins between TaHKT2;2 homeologous genes and other group II HKT gene families within and across species likely reflect functional diversity for ion selectivity and transport in plants. Evidence indicated that neither TaHKT2;2 nor TaHKT2;1 were associated with primary root Na(+) uptake but TaHKT2;1 may be associated with trait variation for Na(+) exclusion and yield in some but not all saline environments.

    Knowledge of the risk factor profile of patients presenting with late-stage age-related macular degeneration (AMD) could help identify the most frequent modifiable AMD precursors among people who are referred for treatment. We aimed to assess dietary behaviours by comparing adjusted mean intakes of micronutrients and major food groups (fruits, vegetables, fish) among patients with AMD and a sample of age-sex-matched controls. Cross-sectional analysis of 480 late AMD cases and 518 population-based age-sex-matched controls with no AMD signs. AMD cases (aged 60+ years) were those presenting for treatment to a hospital eye clinic in Sydney, Australia, during 2012-2015. The comparator group were obtained from a cohort study (Blue Mountains Eye Study; Sydney, Australia) during 2002-2009. Dietary intake was assessed using a semiquantitative food-frequency questionnaire. AMD lesions were assessed from retinal photographs. After multivariable adjustment, patients with late-stage AMD compared with controls had significantly lower intakes of vitamin E (7.4 vs 9.8 mg/day; p<0.0001), beta-carotene (6232 vs 7738 μg/day; p<0.0001), vitamin C (161 vs 184 mg/day; p=0.0002) and folate (498.3 vs 602 μg/day; p<0.0001); but had higher intakes of zinc (13.0 vs 11.9 mg/day; p<0.0001). A significantly lower proportion of patients with late AMD met the recommended intake of vegetables than controls: 52.9% versus 64.5%; p=0.0002. This study showed significant differences in intakes of vitamins C and E, beta-carotene, folate and vegetables between patients with late-stage AMD and healthy controls, and thus has provided a better understanding of the nutritional intake of patients presenting with advanced AMD.

    Mental illness is a significant and growing problem in Canadian healthcare organizations, leading to tremendous personal, social and financial costs for individuals, their colleagues, their employers and their patients. Early and appropriate intervention is needed, but unfortunately, few workers get the help that they need in a timely way due to barriers related to poor mental health literacy, stigma, and inadequate access to mental health services. Workplace education and training is one promising approach to early identification and support for workers who are struggling. Little is known, however, about what approach is most effective, particularly in the context of healthcare work. The purpose of this study is to compare the impact of a customized, contact-based education approach with standard mental health literacy training on the mental health knowledge, stigmatized beliefs and help-seeking/help-outreach behaviors of healthcare employees. A multi-centre, randomized, two-group parallel group trial design will be adopted. Two hundred healthcare employees will be randomly assigned to one of two educational interventions: Beyond Silence, a peer-led program customized to the healthcare workplace, and Mental Health First Aid, a standardized literacy based training program. Pre, post and 3-month follow-up surveys will track changes in knowledge (mental health literacy), attitudes towards mental illness, and help-seeking/help-outreach behavior. An intent-to-treat, repeated measures analysis will be conducted to compare changes in the two groups over time in terms of the primary outcome of behavior change. Linear regression modeling will be used to explore the extent to which knowledge, and attitudes predict behavior change. Qualitative interviews with participants and leaders will also be conducted to examine process and implementation of the programs. This is one of the first experimental studies to compare outcomes of standard mental health literacy training to an

    Drug-eluting stents (DES) significantly reduced the incidence of in-stent restenosis (ISR). However, ISR still exists in the contemporary DES era. Previously deemed to be a benign process, ISR leads to complex presentation and intervention. This study aimed to compare the presentation and outcome of DES-ISR versus de novo lesions. We performed a retrospective analysis of 11,666 patients receiving percutaneous coronary intervention from 2003 to 2017 and divided them into 2 groups by de novo stenosis and ISR. They were matched based on common cardiovascular risk factors at a 4:1 ratio, respectively. After matching, a total of 1,888 patients with 3,126 de novo lesions and 472 patients with 508 ISR lesions were analyzed. Patients with ISR presented more often with unstable angina (61% vs 45%, p stent technique and should motivate the continued development of fully bioresorbable scaffolds.

    Weakly-coupled TeV-scale particles may mediate the interactions between normal matter and dark matter. If so, the LHC would produce dark matter through these mediators, leading to the familiar "mono-X" search signatures, but the mediators would also produce signals without missing momentum via the same vertices involved in their production. This document from the LHC Dark Matter Working Group suggests how to compare searches for these two types of signals in case of vector and axial-vector mediators, based on a workshop that took place on September 19/20, 2016 and subsequent discussions. These suggestions include how to extend the spin-1 mediated simplified models already in widespread use to include lepton couplings. This document also provides analytic calculations of the relic density in the simplified models and reports an issue that arose when ATLAS and CMS first began to use preliminary numerical calculations of the dark matter relic density in these models.

    Identifying risk factors for human cancers should consider combinations of genetic variations and environmental exposures. Several polymorphisms in DNA repair genes have impact on repair and cancer susceptibility. We focused on X-ray repair cross-complementing group 1 (XRCC1), Xeroderma pigmentosum D (XPD) and apurinic/apyrimidinic endonuclease (APE1) as these are most extensively studied in cancer. Present study was conducted to determine distribution of XRCC1 C26304T, G27466A, G23591A, APE1 T2197G and XPD A35931C gene polymorphisms in North Indian population and compare with different populations globally. PCR-based analysis was conducted in 209 normal healthy individuals of similar ethnicity. Allelic frequencies in wild type of XRCC1 C26304T were 91.1% C(Arg); G27466A 62.9% G(Arg); G23591A 60.3% G(Arg); APE1 T2197G 75.1% T(Asp) and XPD A35931C 71.8% A(Lys). The variant allele frequency were 8.9% T(Trp) in XRCC1 C26304T; 37.1% A(His) in G27466A; 39.7% A(Gln) in G23591A; 24.9% G(Glu) in APE1 and 28.2% C(Gln) in XPD respectively. We further compared frequency distribution for these genes with various published studies in different ethnicity. Our results suggest that frequency in these DNA repair genes exhibit distinctive pattern in India that could be attributed to ethnicity variation. This could assist in high-risk screening of humans exposed to environmental carcinogens and cancer predisposition in different ethnic groups.

    Full Text Available Background: There is a growing interest in using group cognitive–behavioral therapy (CBT with people who have Asperger syndrome (AS and comorbid mental health problems. This study aims to assess the cost-effectiveness of modified group CBT for adults with AS experiencing co-occurring anxiety compared to treatment-as-usual. Methods: Economic evaluation alongside a pilot, multicenter, single-blind, randomized controlled crossover trial. Costs from the UK public sector (National Health Service and Social Services and societal perspectives, quality-adjusted life years (QALYs, incremental net (monetary benefit (INB, expected value of perfect information, expected value of sample information, expected net gain of sampling, and efficient sample size of a future trial are reported. Results: Over 48 weeks, from the societal perspective, CBT results in additional costs of £6,647, with only a 0.015 incremental gain in QALYs, leading to a negative INB estimate of £6,206 and a 23% probability of cost-effectiveness at a threshold of £30,000/QALY. Results from sensitivity analyses support the unlikely cost-effectiveness of CBT but indicate the potential for cost-effectiveness over longer time horizons. Eliminating decision uncertainty is valued at £277 million, and the efficient sample size for a future trial is estimated at 1,200 participants per arm. Limitations: Relatively small sample size and prevalence of missing data present challenges to the interpretation of the results. Conclusions: Current evidence from this small pilot study suggests that, on average, modified group CBT is not cost-effective. However, there is much decision uncertainty so such a conclusion could be wrong. A large, full-scale trial to reduce uncertainty would be an efficient investment for the UK health economy.

    In this report, the health effects of low-level doses of radiation are considered by reference to published epidemiological surveys. The work was carried out with three objectives in mind: 1. to provide a comprehensive and critical review of the subject; 2. to seek consistent indications of particular health effects by collating results and comparing with those from surveys at moderate-level doses; 3. to provide an authoritative view on the epidemiology of low-level radiation-induced health effects. Vol E (DRAFT A) is appended and contains group collation tables. Epidemiological surveys can be conveniently divided into four classes (A, B, C, D) according to the phase of life when irradiation occurs or the effect is diagnosed. The first of the classes (A) is addressed here; this class is concerned with possible effects arising from radiation received by a parent before conception. Possible effects of preconception irradiation were identified under four broad groupings. These are Down's syndrome, ''Indicators of Reproductive Damage'' (mainly Primary Sterility, Congenital Abnormalities, Sex Ratio, Fetal Mortality, Infant Mortality), Childhood Malignancies, and Chromosomal Changes in Abortuses. Information about each survey, and comparisons with results from moderate-level dose surveys, are contained in synopses that are set out in the Appendix.

    In developing a model of palliative care, the attitudes, needs, and requirements of its beneficiaries recognizing the limited remaining life expectancy need to be met. We aimed to map and compare these issues at the end of life in the groups of patients with advanced cancer and elderly individuals. The prospective study based on the analysis of semistructured interviews was conducted. Fifty individuals aged older than 85 and 50 incurable patients with advanced cancer were studied. Transcripts of interviews were analyzed qualitatively (the interviews were divided into logically completed themes, and the compliance of each with one of the levels of Abraham Maslow pyramid was determined) and quantitatively (data comparisons of 2 groups were tested in bivariate analysis using Pearson χ 2 or Fisher exact test. Two-sided significance tests were used; P value of Maslow pyramid. Their comparison showed small differences in the narratives of the patients with advanced cancer and elderly individuals aged 85 and older-concerning the past, present, and future terms of lives. In studied themes explicitly prevail the stories that are consistent with satisfaction of the upper levels of the hierarchy of needs and demands of Maslow: social relation (belonging), love, esteem, and transcendence. The attitudes, needs, and requirements at the end of life of the people are basically similar, regardless of what determined the sense of limitation of the remaining life-incurable disease or advanced age.

    Full Text Available To determine the role of markers of plasma protein damage by glycation, oxidation and nitration in microalbuminuria onset or subsequent decline of glomerular filtration rate (termed "early GFR decline" in patients with type 1 diabetes.From the 1(st Joslin Kidney Study, we selected 30 patients with longstanding normoalbuminuria and 55 patients with new onset microalbuminuria. Patients with microalbuminuria had 8-12 years follow-up during which 33 had stable GFR and 22 early GFR decline. Mean baseline GFR(CYSTATIN C was similar between the three groups. Glycation, oxidation and nitration markers were measured in protein and ultrafiltrate at baseline by liquid chromatography-tandem mass spectrometry using the most reliable methods currently available.Though none were significantly different between patients with microalbuminuria with stable or early GFR decline, levels of 6 protein damage adduct residues of plasma protein and 4 related free adducts of plasma ultrafiltrate were significantly different in patients with microalbuminuria compared to normoalbuminuria controls. Three protein damage adduct residues were decreased and 3 increased in microalbuminuria while 3 free adducts were decreased and one increased in microalbuminuria. The most profound differences were of N-formylkynurenine (NFK protein adduct residue and N(ω-carboxymethylarginine (CMA free adduct in which levels were markedly lower in microalbuminuria (P<0.001 for both.Complex processes influence levels of plasma protein damage and related proteolysis product free adducts in type 1 diabetes and microalbuminuria. The effects observed point to the possibility that patients who have efficient mechanisms of disposal of damaged proteins might be at an increased risk of developing microalbuminuria but not early renal function decline. The findings support the concept that the mechanisms responsible for microalbuminuria may differ from the mechanisms involved in the initiation of early

    Full Text Available Background: Hypercholesterolemia is a major risk factor for coronary heart disease. Clinical studies have shown that lowering elevated serum cholesterol levels, particularly low-density lipoprotein cholesterol (LDL-C, is beneficial for patients with borderline to mildly elevated serum total cholesterol (TC levels (5.0–6.0 mmol/L. Policosanol is a cholesterol-lowering drug made from purified sugar cane wax. The therapeutic range of policosanol is 5 to 20 mg/d. Objective: This study investigated the efficacy and tolerability of policosanol 5 mg/d in patients with borderline to mildly elevated serum TC levels. Methods: This 14-week, single-center, prospective, double-blind, placebo-controlled, parallel-group, comparative study was conducted in men and women aged 25 to 75 years with a serum TC level ≥4.8 to <6.0 mmol/L. After a 6-week run-in period in which patients were placed on therapeutic lifestyle changes, in particular a cholesterol-lowering diet, patients were randomly assigned to receive policosanol 5-mg tablets or placebo tablets once daily with the evening meal for 8 weeks, and the diet was continued throughout the study. Lipid profile variables, safety indicators, adverse events (AEs, and compliance with study medications were assessed. Results: One hundred patients (71 women, 29 men; mean [SD] age, 52 [10] years entered the study after the dietary run-in period. After 8 weeks of treatment, the mean (SD serum LDL-C level decreased significantly in the policosanol group (P<0.001 vs baseline and placebo from 3.57 (0.30 mmol/L to 2.86 (0.41 mmol/L (change, −19.9%. Significantly more patients in the policosanol group (42 patients [84%] achieved a ≥15% decrease in serum LDL-C than in the placebo group (2 patients [4%] (P<0.001.

    Full Text Available Background/Aim. Global budget per calendar year is a traditional method of funding hospitals in Serbia. Diagnose related groups (DGR is a method of hospital payment based on classification of patients into groups with clinically similar problems and similar utilization of hospital resources. The aim of this study was to compare current methods of hospital services payment with the projected costs by DRG payment method in urology. Methods. The data were obtained from the information system used in the Clinical Hospital Center “Dr. Dragiša Mišović” - Dedinje in Belgrade, Serbia. The implemented hospital information system was the main criterion for selection of healthcare institutions. The study included 994 randomly selected patients treated surgically and conservatively in 2012. Results. Average costs under the current payment method were slightly higher than those projected by DRG, however, the variability was twice as high (54,111 ± 69,789 compared to 53,434 ± 32,509, p < 0,001 respectively. The univariate analysis showed that the highest correlation with the current payment method as well as with the projected one by DRG was observed in relation to the number of days of hospitalization (ρ = 0.842, p < 0.001, and ρ = 0.637, p < 0.001, respectively. Multivariate regression models confirmed the influence of the number of hospitalization days to costs under the current payment system (β = 0.843, p < 0.001 as well as under the projected DRG payment system (β = 0.737, p < 0.001. The same predictor was crucial for the difference in the current payment method and the projected DRG payment methods (β = 0.501, p <0.001. Conclusion. Payment under the DRG system is administratively more complex because it requires detailed and standardized coding of diagnoses and procedures, as well as the information on the average consumption of resources (costs per DRG. Given that aggregate costs of treatment under two hospital payment methods compared

Methods A systematic review with meta-analysis. Computerised bibliographic database were searched up to January 2008 for randomised controlled trials evaluating group-based DSME for adult type-2 diabetics versus routine treatment where the intervention had at least one session and =/>6 months follow-up. At least two reviewers independently extracted data and assessed study quality. Results In total 21 studies (26 publications, 2833 participants) were included. Of all the participants 4 out of 10 were male, baseline age was 60 years, BMI 31.6, HbA1c 8.23%, diabetes duration 8 years and 82% used medication. For the main clinical outcomes, HbA1c was significantly reduced at 6 months (0.44% points; P = 0.0006, 13 studies, 1883 participants), 12 months (0.46% points; P = 0.001, 11 studies, 1503 participants) and 2 years (0.87% points; P 1, 3 studies, 397 participants) and fasting blood glucose levels were also significantly reduced at 12 months (1.26 mmol/l; P 1, 5 studies, 690 participants) but not at 6 months. For the main lifestyle outcomes, diabetes knowledge was improved significantly at 6 months (SMD 0.83; P = 0.00001, 6 studies, 768 participants), 12 months (SMD 0.85; P 1, 5 studies, 955 participants) and 2 years (SMD 1.59; P = 0.03, 2 studies, 355 participants) and self-management skills also improved significantly at 6 months (SMD 0.55; P = 0.01, 4 studies, 534 participants). For the main psychosocial outcomes, there were significant improvement for empowerment/self-efficacy (SMD 0.28, P = 0.01, 2 studies, 326 participants) after 6 months. For

    A substantial burden is placed on family caregivers of patients diagnosed with brain cancers. Despite this, the support needs of the caregivers are often under-recognised and not addressed adequately in current routine and patient centred clinical care. The Carer Support Needs Assessment Tool (CSNAT) is a validated instrument designed to systematically identify and address caregiver needs [corrected]. It has been trialled in an Australian palliative care community setting using a stepped wedge cluster design involving 322 family carers of terminally ill patients. The current article reports on a subset from this trial, 29 caregivers of patients with primary brain cancer, and compares their profile and outcomes to those of other cancer groups. Caregiver strain was assessed using the Family Appraisal of Caregiving Questionnaire, caregiver physical and mental wellbeing using SF12 and caregiver workload using a questionnaire on support with activities of daily living (ADL). In comparison to caregivers of patients with all other cancers, the primary brain cancer group had significantly higher levels of caregiver strain, lower levels of mental wellbeing and a higher level of ADL workload. Their physical wellness also deteriorated significantly over time. An action plan approach led to practical solutions for addressing highlighted concerns. Four themes evolved from the family caregivers' feedback interviews: The extremely challenging caregiver experience with brain cancer; the systematic and practical approach of the CSNAT during rapid changes; connection with health professionals, feeling acknowledged and empowered; and timely advice and assurance of support during the caregiving journey. This preliminary study has demonstrated that the CSNAT provides a practical and useful tool for assessing the support needs of family caregivers of patients with brain cancer and has provided the basis for a larger scale, longitudinal study that allows a more detailed characterisation

Material and Methods: A random population sample (N = 682 of all middle-aged Malmö males and females was given a questionnaire with the 14-item JCQ and 11-item DCQ for the job control and job demands. The JCQ job control and job demands scores were calculated in 3 different ways: using the 14-item JCQ standard scale formulas (method 1; dropping 3 job control items and using the 11-item JCQ standard scale formulas with additional scale weights (method 2; and the approach of the IPD Group (method 3, dropping 3 job control items, but using the simple 11-item summation-based scale formulas. The high job strain was defined as a combination of high demands and low control. Results: Between the 2 questionnaires, false negatives for the high job strain were much greater than false positives (37–49% vs. 7–13%. When the method 3 was applied, the sensitivity of the JCQ for the high job strain against the DCQ was lowest (0.51 vs. 0.60–0.63 when the methods 1 and 2 were applied, although the specificity was highest (0.93 vs. 0.87–0.89 when the methods 1 and 2 were applied. The prevalence of the high job strain with the JCQ (the method 3 was applied was considerably lower (4–7% than with the JCQ (the methods 1 and 2 were applied and the DCQ. The number of congruent cases for the high job strain between the 2 questionnaires was smallest when the method 3 was applied. Conclusions: The IPD-Work Consortium approach showed 2 major weaknesses to be used for epidemiological studies on the high job strain and health outcomes as compared to the standard JCQ methods: the greater misclassification of the high job strain and lower prevalence of the high job strain.

  9. Phylogenetic relationship and virulence inference of Streptococcus Anginosus Group: curated annotation and whole-genome comparative analysis support distinct species designation

    Science.gov (United States)

    2013-01-01

    Background The Streptococcus Anginosus Group (SAG) represents three closely related species of the viridans group streptococci recognized as commensal bacteria of the oral, gastrointestinal and urogenital tracts. The SAG also cause severe invasive infections, and are pathogens during cystic fibrosis (CF) pulmonary exacerbation. Little genomic information or description of virulence mechanisms is currently available for SAG. We conducted intra and inter species whole-genome comparative analyses with 59 publically available Streptococcus genomes and seven in-house closed high quality finished SAG genomes; S. constellatus (3), S. intermedius (2), and S. anginosus (2). For each SAG species, we sequenced at least one numerically dominant strain from CF airways recovered during acute exacerbation and an invasive, non-lung isolate. We also evaluated microevolution that occurred within two isolates that were cultured from one individual one year apart. Results The SAG genomes were most closely related to S. gordonii and S. sanguinis, based on shared orthologs and harbor a similar number of proteins within each COG category as other Streptococcus species. Numerous characterized streptococcus virulence factor homologs were identified within the SAG genomes including; adherence, invasion, spreading factors, LPxTG cell wall proteins, and two component histidine kinases known to be involved in virulence gene regulation. Mobile elements, primarily integrative conjugative elements and bacteriophage, account for greater than 10% of the SAG genomes. S. anginosus was the most variable species sequenced in this study, yielding both the smallest and the largest SAG genomes containing multiple genomic rearrangements, insertions and deletions. In contrast, within the S. constellatus and S. intermedius species, there was extensive continuous synteny, with only slight differences in genome size between strains. Within S. constellatus we were able to determine important SNPs and changes in

    To assess the cost-effectiveness of group cognitive behavior therapy (gCBT) in comparison with routine primary care for women with postnatal depression in the UK. Our analysis was based on a systematic literature review of the relative clinical effectiveness of gCBT compared with routine primary care and further reviews, supplemented with expert opinion of the likely cost of providing gCBT and the duration of comparative advantage for gCBT. Raw data were used to estimate a statistical relationship between changes in the Edinburgh Postnatal Depression Score (EPDS) values and changes in short-form six dimensions' (SF-6D) values. A mathematical model was constructed, and probabilistic sensitivity analyses were undertaken to estimate the mean cost per quality-adjusted life-year (QALY) and to evaluate the expected value of perfect information (EVPI). The mean cost per QALY from the stochastic analysis was estimated to be pound36,062; however, there was considerable uncertainty around this value. The EVPI was estimated to be greater than pound64 million; the key uncertainties were in the cost per woman of providing treatment and in the statistical relationship between changes in EPDS values and changes in SF-6D values. The expected value of perfect partial information for both of these parameters was in excess of pound25 million. Given the current information, the use of gCBT does not appear to be cost-effective; however, this decision is uncertain. The value of information analyses conducted indicates that further research to provide robust information on key parameters is needed and appears justified in cost-effective terms.

    Evidence from various epidemiological studies and experimental animal studies has linked adverse intrauterine circumstances with health problems in adult life. This field of investigation is known as Developmental Origins of Health and Disease (DOHaD). Studies investigating the relation between developing polycystic ovary syndrome (PCOS) in adulthood and birth weight have yielded inconsistent results: PCOS is described more often in women with low birth weight and high birth weight, while other studies have failed to establish any relation. In this retrospective case-control study, we evaluated whether women diagnosed with PCOS had lower birth weight compared to women with a regular menstrual cycle (controls). Binary logistic regression models were used to analyze the data and correct for known confounders. About 65 women with PCOS and 96 controls were recruited for this purpose. The average birth weight of PCOS women (3357 g) did not differ from the average birth weight of controls (3409 g). Mean age at menarche differed significantly between groups, 13.7  years and 12.8  years (p = 0.006), respectively, for PCOS women and controls. In conclusion, we could not confirm the effect of adverse intrauterine conditions, reflected in birth weight, on developing PCOS.

    Non-invasive fetal RHD genotyping in Australia to reduce anti-D usage will need to accommodate both prolonged sample transport times and a diverse population demographic harbouring a range of RHD blood group gene variants. We compared RHD genotyping accuracy using two blood sample collection tube types for RhD negative women stratified into deleted RHD gene haplotype and RHD gene variant cohorts. Maternal blood samples were collected into EDTA and cell-free (cf)DNA stabilising (BCT) tubes from two sites, one interstate. Automated DNA extraction and polymerase chain reaction (PCR) were used to amplify RHD exons 5 and 10 and CCR5. Automated analysis flagged maternal RHD variants, which were classified by genotyping. Time between sample collection and processing ranged from 2.9 to 187.5 hours. cfDNA levels increased with time for EDTA (range 0.03-138 ng/μL) but not BCT samples (0.01-3.24 ng/μL). For the 'deleted' cohort (n=647) all fetal RHD genotyping outcomes were concordant, excepting for one unexplained false negative EDTA sample. Matched against cord RhD serology, negative predictive values using BCT and EDTA tubes were 100% and 99.6%, respectively. Positive predictive values were 99.7% for both types. Overall 37.2% of subjects carried an RhD negative baby. The 'variant' cohort (n=15) included one novel RHD and eight hybrid or African pseudogene variants. Review for fetal RHD specific signals, based on one exon, showed three EDTA samples discordant to BCT, attributed to high maternal cfDNA levels arising from prolonged transport times. For the deleted haplotype cohort, fetal RHD genotyping accuracy was comparable for samples collected in EDTA and BCT tubes despite higher cfDNA levels in the EDTA tubes. Capacity to predict fetal RHD genotype for maternal carriers of hybrid or pseudogene RHD variants requires stringent control of cfDNA levels. We conclude that fetal RHD genotyping is feasible in the Australian environment to avoid unnecessary anti

    Purpose: Survivors of pediatric Hodgkin lymphoma (HL) are recognized to have an increased risk of delayed adverse health outcomes related to radiation therapy (RT). However, the necessary latency required to observe these late effects means that the estimated risks apply to outdated treatments. We sought to compare the normal tissue dose received by children treated for HL and enrolled in the Childhood Cancer Survivor Study (CCSS) (diagnosed 1970-1986) with that of patients treated in recent Children's Oncology Group (COG) trials (enrolled 2002-2012). Methods and Materials: RT planning data were obtained for 50 HL survivors randomly sampled from the CCSS cohort and applied to computed tomography planning data sets to reconstruct the normal tissue dosimetry. For comparison, the normal tissue dosimetry data were obtained for all 191 patients with full computed tomography–based volumetric RT planning on COG protocols AHOD0031 and AHOD0831. Results: For early-stage patients, the mean female breast dose in the COG patients was on average 83.5% lower than that for CCSS patients, with an absolute reduction of 15.5 Gy. For advanced-stage patients, the mean breast dose was decreased on average by 70% (11.6 Gy average absolute dose reduction). The mean heart dose decreased on average by 22.9 Gy (68.6%) and 17.6 Gy (56.8%) for early- and advanced-stage patients, respectively. All dose comparisons for breast, heart, lung, and thyroid were significantly lower for patients in the COG trials than for the CCSS participants. Reductions in the prescribed dose were a major contributor to these dose reductions. Conclusions: These are the first data quantifying the significant reduction in the normal tissue dose using actual, rather than hypothetical, treatment plans for children with HL. These findings provide useful information when counseling families regarding the risks of contemporary RT.

    Full Text Available Efficacy of short-course therapy with cephalosporins for treatment of group A β-hemolytic streptococcus (GABHS pharyngitis is still controversial. Subjects were 226 children with a history of at least one episode of GABHS pharyngitis. Recurrence within the follow-up period (3 weeks after initiation of therapy occurred in 7 of the 77 children in the 5-day treatment group and in 1 of the 149 children in the 10-day treatment group; the incidence of recurrence being significantly higher in the 5-day treatment group. Bacteriologic treatment failure (GABHS isolation without overt pharyngitis at follow-up culture was observed in 7 of the 77 children in the 5-day treatment group and 17 of the 149 children in the 10-day treatment group. There was no statistical difference between the two groups. A 5-day course of oral cephalosporins is not always recommended for treatment of GABHS pharyngitis in children who have repeated episodes of pharyngitis.

    In Cancer and Leukemia Group B 39801, we evaluated whether induction chemotherapy before concurrent chemoradiotherapy would result in improved survival and demonstrated no significant benefit from the addition of induction chemotherapy. The primary objective of this analysis was to dichotomize patients into prognostic groups using factors predictive of survival and to investigate whether induction chemotherapy was beneficial in either prognostic group. A Cox proportional hazard model was used to assess the impact on survival of the following factors: (>or=70 versus or=13 g/dl), performance status (PS) (1 versus 0), weight loss (>or=5% versus or=5%, age >or=70 years, PS of 1, and hgb or=2 poor prognostic factors (n = 165) or or=2 versus patients with or=2 factors (HR = 0.86, 95% CI, 0.63-1.17; p = 0.34) or group.

    Background In Cancer and Leukemia Group B 39801, we evaluated whether induction chemotherapy before concurrent chemoradiotherapy would result in improved survival, and demonstrated no significant benefit from the addition of induction chemotherapy. The primary objective of this analysis was to dichotomize patients into prognostic groups using factors predictive of survival, and to investigate if induction chemotherapy was beneficial in either prognostic group. Patients and Methods A Cox proportional hazard model was used to assess the impact on survival of the following factors: (≥ 70 vs. < 70 years), gender, race, stage (IIIB vs. IIIA), hemoglobin (hgb) (< 13 vs. ≥13 g/dl), performance status (PS) (1 vs.0), weight loss (≥5% vs. < 5%), treatment arm, and the interaction between weight loss and hgb. Results Factors predictive of decreased survival were weight loss ≥ 5%, age ≥ 70 years, PS of 1, and hgb < 13 g/dl (p<0.05). Patients were classified as having ≥2 poor prognostic factors (n=165) or ≤ 1 factor (n=166). The hazard ratio (HR) for overall survival for the patients with ≥ 2 versus patients with ≤ 1 was 1.88 (95% CI, 1.49 to 2.37; p= < 0.0001); median survival times observed were 9 (95% CI, 8 to 11) and 18 (95% CI, 16 to 24) months, respectively. There was no significant difference in survival between treatment arms in patients with ≥ 2 factors (HR=0.86, 95% CI, 0.63 to 1.17; p=0.34) or ≤1 factor (HR=0.97, 95% CI, 0.70 to 1.35; p=0.87) Conclusions There is no evidence that induction chemotherapy is beneficial in either prognostic group.

    2016-07-01

    Purpose The neck disability index (NDI) as a 10-item patient reported outcome (PRO) measure is the most commonly used whiplash associated disorders (WAD) assessment tool. However, statistical rigor and factor structure are not definitive. To date, confirmatory factor analysis (CFA) has not examined whether the factor structure generalizes across different groups (e.g., WAD versus non-WAD). This study aimed to determine the psychometric properties of the NDI in these population groups. This study used CFA to analyze NDI baseline-data for WAD (n = 804; 69 % females) and non-WAD (n = 963; 67 % females), each for the full sample and separate genders. Invariance analyses examined the NDI structure across the four groups. Across both populations and gender subgroups the one-factor solutions consistently showed better model fit over two-factor solutions. The NDI was best characterized as one-dimensional and invariant across multiple sub-groups. The NDI remains a valid PRO in WAD populations that provides acceptable measurement of neck status that is appropriate for basic functional assessment across genders. However, it is recommended that both clinicians and researchers initiate the transition toward more rigorous and less ambiguous PRO measurement tools for WAD patients and research. This future graduated movement toward other PROs should consider both regional PROs and computerized decision support systems, initially measured concurrently with the NDI to establish ways to convert existing scored data prior to their singular use.

    Residential energy cost, an important part of the household budget, varies significantly across different population groups. In the United States, researchers have conducted many studies of household fuel consumption by fuel type -- electricity, natural gas, fuel oil, and liquefied petroleum gas (LPG) -- and by geographic areas. The results of past research have also demonstrated significant variation in residential energy use across various population groups, including white, black, and Latino. However, research shows that residential energy demand by fuel type for Latinos, the fastest-growing population group in the United States, has not been explained by economic and noneconomic factors in any available statistical model. This paper presents a discussion of energy demand and expenditure patterns for Latino and non-Latino households in the United States. The statistical model developed to explain fuel consumption and expenditures for Latino households is based on Stone and Geary`s linear expenditure system model. For comparison, the authors also developed models for energy consumption in non-Latino, black, and nonblack households. These models estimate consumption of and expenditures for electricity, natural gas, fuel oil, and LPG by various households at the national level. The study revealed significant variations in the patterns of fuel consumption for Latinos and non-Latinos. The model methodology and results of this research should be useful to energy policymakers in government and industry, researchers, and academicians who are concerned with economic and energy issues related to various population groups.

    Herein, three types of upconverting NaGdF{sub 4}:Yb/Er nanoparticles (UCNPs) have been synthesized via one-step hydrothermal synthesis with polyethylene glycol (PEG), polyethylenimine (PEI) and 6-aminocapronic acid (6AA) functionalization. To evident the presence of these groups, FTIR spectra and ζ-potentials were measured to support the successful capping of PEG, PEI and 6AA on the UCNPs. The regular morphology and cubic phase of these functionalized UCNPs were attributed to the capping effect of the surfactants. Tunable upconversion luminescence (UCL) from red to green were observed under 980 nm laser excitation and the UCL tuning was attributed to the presence of various surface ligands. Moreover, surface group dependent UCL bioimaging was performed in HeLa cells. The enhanced UCL bioimaging demonstrated by PEI functionalized UCNPs evident high cell uptake. The significant cell uptake is explained by the electrostatic attraction between the amino groups (–NH{sub 2}) and the cell membrane. Moreover, the functionalized UCNPs demonstrated low cytotoxicity in MTT assay. Additional, paramagnetic property was presented by these UCNPs under magnetic field. - Highlights: • Tunable upconversion emission by capped functional groups under fixed composition. • Surface dependent upconversion luminescence bioimaging in HeLa cells. • Low cytotoxicity. • Additional paramagnetic property due to Gd{sup 3+} ions.

    Studies of large policy interventions typically do not involve randomization. Adjustments, such as matching, can remove the bias due to observed covariates, but residual confounding remains a concern. In this paper we introduce two analytical strategies to bolster inferences of the effectiveness of policy interventions based on observational data. First, we identify how study groups may differ and then select a second comparison group on this source of difference. Second, we match subjects using a strategy that finely balances the distributions of key categorical covariates and stochastically balances on other covariates. An observational study of the effect of parity on the severely ill subjects enrolled in the Federal Employees Health Benefits (FEHB) Program illustrates our methods.

    Smoking and drinking are two predisposing factors for dyslipidemia. Exercise has been proposed as a strategy to improve the blood lipids. However, it remains unclear how smoking and drinking jointly affect blood lipids and whether exercise influences their effects. To evaluate the effects of smoking and drinking, either alone or in combination, on lipid-related indices in both exercise and non-exercise groups among Chinese men. This study was conducted in a health examination center between 2015 and 2016. A sample of 6,179 male subjects was divided into exercise and non-exercise groups. Logistic and linear regression analyses were used to calculate the odds ratios for abnormal lipid-related indices and correlation coefficients between smoking/drinking and lipid-related indices. In the study population, the percentage of stable smokers and stable drinkers was 46.3% (2,860/6,179) and 77.6% (4,795/6,179), respectively. An increased smoking amount was significantly associated with an elevated triglyceride (TG) level and a decreased high-density lipoprotein cholesterol (HDL-C) level. Heavier smokers had higher odds ratios for high TG and low HDL-C. Heavier drinkers had higher levels of total cholesterol (TC), TG, and HDL-C and higher odds ratios for high TC and high TG but lower odds ratio for low HDL-C. The exercise group had lower TG levels and higher HDL-C levels than did the non-exercise group. Both heavier smoking and heavier drinking were associated with poorer TG levels, and the results suggest that drinking may be helpful for HDL-C. Exercise may relieve the negative effects of smoking and drinking.

    Full Text Available Introduction. Recent evidence of safety and efficacy of Bone Marrow Mononuclear Cells (BMMNC in spinal cord injury makes the Bone Marrow (BM CD34+ percentage and the BMMNC count gain significance. The indices of BM that change with body mass index and aging in general population have been reported but seldom in Spinal Cord Injury (SCI victims, whose parameters of relevance differ from general population. Herein, we report the indices of BMMNC in SCI victims. Materials and Methods. BMMNCs of 332 SCI patients were isolated under GMP protocols. Cell count by Trypan blue method and CD34+ cells by flow cytometry were documented and analysed across ages and gender. Results. The average BMMNC per ml in the age groups 0–20, 21–40, 41–60, and 61–80 years were 4.71, 4.03, 3.67, and 3.02 million and the CD34+ were 1.05%, 1.04%, 0.94%, and 0.93% respectively. The decline in CD34+ was sharp between 20–40 and 40–60 age groups. Females of reproductive age group had lesser CD34+. Conclusion. The BMMNC and CD34+ percentages decline with aging in SCI victims. Their lower values in females during reproductive age should be analysed for relevance to hormonal influence. This study offers reference values of BMMNC and CD34+ of SCI victims for successful clinical application.

    Very little is known about arsenic (As) metabolism in healthy populations that are not exposed to high concentrations of As in their food or water. Here we present a study with healthy volunteers from three different ethnic groups, residing in Leicester, UK, which reveals statistically significant differences in the levels of total As in urine and fingernail samples. Urine (n = 63), hair (n = 36) and fingernail (n = 36) samples from Asians, Somali Black-Africans and Whites were analysed using inductively coupled plasma mass spectrometry (ICP-MS) and graphite furnace atomic absorption spectroscopy (GF-AAS). The results clearly show that the total concentrations of As in urine and fingernail samples of a Somali Black-African population (urine 7.2 μg/g creatinine; fingernails 723.1 μg/kg) are significantly (P 0.05) in the level of As in the hair samples from these three groups; Somali Black-Africans (116.0 μg/kg), Asians (117.4 μg/kg) and Whites (141.2 μg/kg). Significantly different levels of total As in fingernail and urine and a higher percentage of urinary DMA in the Somali Black-Africans are suggestive of a different pattern of As metabolism in this ethnic group

    There have been reports and claims in the psychotherapeutic literature that the consideration of recent dreams can result in personal realizations and insight. There is theoretical support for these claims from work on rapid eye movement (REM) sleep having a function of the consolidation of emotional memories and the creative formation of connections between new and older memories. To investigate these claims, 11 participants (10 females, one male) reported and considered a recent home dream in a dream discussion group that following the "Appreciating dreams" method of Montague Ullman. The group ran 11 times, each participant attending and participating once. A further nine participants (seven females, two males) reported and considered a recent home dream in a group that followed the "Listening to the dreamer" method of Michael Schredl. The two studies each had a control condition where the participant also reported a recent event, the consideration of which followed the same technique as was followed for the dream report. Outcomes of the discussions were assessed by the participants on the Gains from Dream Interpretation (GDI) scale, and on its counterpart, the Gains from Event Interpretation scale. High ratings on the GDI experiential-insight subscale were reported for both methods, when applied to dreams, and for the Ullman method Exploration-Insight ratings for the dream condition were significantly higher than for the control event condition. In the Ullman method, self-assessment of personal insight due to consideration of dream content was also significantly higher than for the event consideration condition. The findings support the view that benefits can be obtained from the consideration of dream content, in terms of identifying the waking life sources of dream content, and because personal insight may also occur. To investigate the mechanisms for the findings, the studies should be repeated with REM and non-REM dream reports, hypothesizing greater insight

    Hepatocellular carcinoma (HCC) can be diagnosed based on characteristic findings of arterial-phase enhancement and portal/delayed 'washout' in cirrhotic patients. Several countries and major academic societies have proposed varying specific diagnostic criteria for HCC, largely reflecting the variable HCC prevalence in different regions and ethnic groups, as well as different practice patterns. In 2014, a new version of Korean practice guidelines for management of HCC was released by the Korean Liver Cancer Study Group (KLCSG) and the National Cancer Center (NCC). According to the KLCSG-NCC Korea practice guidelines, if the typical hallmark of HCC (i.e., hypervascularity in the arterial phase with washout in the portal or 3 min-delayed phases) is identified in a nodule ≥ 1 cm in diameter on either dynamic CT, dynamic MRI, or MRI using hepatocyte-specific contrast agent in high-risk groups, a diagnosis of HCC is established. In addition, the KLCSG-NCC Korea practice guidelines provide criteria to diagnose HCC for subcentimeter hepatic nodules according to imaging findings and tumor marker, which has not been addressed in other guidelines such as Association for the Study of Liver Diseases and European Association for the Study of the Liver. In this review, we briefly review the new HCC diagnostic criteria endorsed by the 2014 KLCSG-NCC Korea practice guidelines, in comparison with other recent guidelines; we furthermore address several remaining issues in noninvasive diagnosis of HCC, including prerequisite of sonographic demonstration of nodules, discrepancy between transitional phase and delayed phase, and implementation of ancillary features for HCC diagnosis

    Atopic dermatitis (AD) still remains one of the most common childhood inflammatory skin diseases. As a chronic disease, it can have a physical and psychological effect on social functioning of the affected child as well as their family. The objective of this study was to evaluate the quality of life of children with AD of different age groups and their families. A total of 203 children with a diagnosis of AD from newborn to 18 years of age and 202 of their parents took part in our study (as one parent did not return the questionnaire). All participants, according to their age, completed the following questionnaires: Infants' Dermatitis Quality of Life Index (IDQOL); Children's Dermatology Life Quality Index (CDLQI) - text and cartoon version; and Dermatitis Family Impact questionnaire (DFI). The mean total IDQOL score in our study was 8.18 (SD = 5.84, n = 120). The mean total CDLQI scores in the groups of children from 7 to 13 and from 14 to 18 years were 8.58 (SD = 4.98, n = 48) and 9.89 (SD = 5.26, n = 35). There was also a proven influence of the child's AD on the quality of life of his parents with the mean score: 7.98 (SD = 6.41, n = 202). The study demonstrated and confirmed that AD significantly impairs the children's quality of life in all age groups and also quality of life of their families. Such data give us patient-oriented information that is of great importance for understanding the situation of individuals with AD and its influence on members of their family. © 2012 The International Society of Dermatology.

    Sex Comb on Midleg (SCM) is a transcriptional repressor in the Polycomb group (PcG), but its molecular role in PcG silencing is not known. Although SCM can interact with Polycomb repressive complex 1 (PRC1) in vitro, biochemical studies have indicated that SCM is not a core constituent of PRC1 or PRC2. Nevertheless, SCM is just as critical for Drosophila Hox gene silencing as canonical subunits of these well-characterized PcG complexes. To address functional relationships between SCM and othe...

    Background The current popularity of mindfulness-based practices has coincided with the increase in access to mobile technology. This has led to many mindfulness apps and programs becoming available, some specifically for children. However, little is known about the experience of engaging with mindfulness through these mediums. Aims To explore children's experience of mindfulness delivered both face-to-face and through a computer game to highlight any differences or similarities. Method A two-armed qualitative focus groups design was used to explore children's experiences. The first arm offered mindfulness exercises in a traditional face-to-face setting with guided meditations. The second arm offered mindfulness exercises through a computer game avatar. Results Themes of relaxation, engagement, awareness, thinking, practice and directing attention emerged from both arms of focus groups. Subthematic codes highlight key differences as well as similarities in the experience of mindfulness. Conclusions These results indicate that mindfulness delivered via technology can offer a rich experience. © The Royal College of Psychiatrists 2017.

    There is a frequent association between renal insufficiency and cardiovascular disease in patients with essential hypertension (HTN). The aim of this study was to analyze the relationship between ECG parameters and the progress of renal damage in patients with treated HTN. 109 patients with HTN had their microalbuminuria monitored over a 3-year time frame. During the last 3 months of follow-up, an ECG was recorded. Patients were divided into 3 groups according to the deterioration of their renal function: normoalbuminuria during the study period (normo-normo; n = 51); normoalbuminuria developing microalbuminuria (normo-micro; n = 29); and microalbuminuria at baseline (micro-micro; n = 29). There were no differences in presence of left ventricular hypertrophy between the 3 groups. RV6/RV5 >1 was observed more frequently as renal function declined ( p = 0.025). The 12-lead QRS-complex voltage-duration product was significantly increased in patients without microalbuminuria at baseline who went on to develop microalbuminuria ( p = 0.006). Patients who developed microalbuminuria during follow-up, with positive Cornell voltage criteria, showed a lesser degree of progression of microalbuminuria when compared with the rest of the subgroups ( p = 0.044). Furthermore, patients with microalbuminuria at baseline treated with angiotensin receptor blockers and diuretics, and positive Cornell voltage criteria, showed a higher degree of microalbuminuria compared to those with negative Cornell voltage criteria ( p = 0.016). In patients with HTN, we identified some ECG parameters, which predict renal disease progression in patients with HTN, which may permit the identification of patients who are at risk of renal disease progression, despite optimal antihypertensive pharmacotherapy.

    Discussion: According to this study, the prevalence of autism among epileptic children is higher than non epileptic ones. As the age of the onset of seizure is lower the prevalence of autism will be higher. Also, the prevalence of autism among epileptic children will be higher as abnormal findings of imaging and known etiologies of seizureincrease. Loss of significant correlations among prevalence of autism and some variables of seizure can be due to few numbers of autistic cases, which were diagnosed in this study comparing with previous studies.

  7. Setting a national minimum standard for health benefits: how do state benefit mandates compare with benefits in large-group plans?

    Many proposed health insurance reforms would establish a federal minimum benefit standard--a baseline set of benefits to ensure that people have adequate coverage and financial protection when they purchase insurance. Currently, benefit mandates are set at the state level; these vary greatly across states and generally target specific areas rather than set an overall standard for what qualifies as health insurance. This issue brief considers what a broad federal minimum standard might look like by comparing existing state benefit mandates with the services and providers covered under the Federal Employees Health Benefits Program (FEHBP) Blue Cross and Blue Shield standard benefit package, an example of minimum creditable coverage that reflects current standard practice among employer-sponsored health plans. With few exceptions, benefits in the FEHBP standard option either meet or exceed those that state mandates require-indicating that a broad-based national benefit standard would include most existing state benefit mandates.

    The use of new methods and an appropriate apparatus has allowed us to make successive measurements of rigor mortis and a study of its evolution in the rat. By a comparative examination on the front and hind limbs, we have determined the following: (1) The muscular mass of the hind limbs is 2.89 times greater than that of the front limbs. (2) In the initial phase rigor mortis is more pronounced in the front limbs. (3) The front and hind limbs reach maximum rigor mortis at the same time and this state is maintained for 2 hours. (4) Resolution of rigor mortis is accelerated in the front limbs during the initial phase, but both front and hind limbs reach complete resolution at the same time.

    Natural populations of the Midas cichlid species in several different crater lakes in Nicaragua exhibit a conspicuous color polymorphism. Most individuals are dark and the remaining have a gold coloration. The color morphs mate assortatively and sympatric population differentiation has been shown based on neutral molecular data. We investigated the color polymorphism using segregation analysis and a candidate gene approach. The segregation patterns observed in a mapping cross between a gold and a dark individual were consistent with a single dominant gene as a cause of the gold phenotype. This suggests that a simple genetic architecture underlies some of the speciation events in the Midas cichlids. We compared the expression levels of several candidate color genes Mc1r, Ednrb1, Slc45a2, and Tfap1a between the color morphs. Mc1r was found to be up regulated in the gold morph. Given its widespread association in color evolution and role on melanin synthesis, the Mc1r locus was further investigated using sequences derived from a genomic library. Comparative analysis revealed conserved synteny in relation to the majority of teleosts and highlighted several previously unidentified conserved non-coding elements (CNEs) in the upstream and downstream regions in the vicinity of Mc1r. The identification of the CNEs regions allowed the comparison of sequences from gold and dark specimens of natural populations. No polymorphisms were found between in the population sample and Mc1r showed no linkage to the gold phenotype in the mapping cross, demonstrating that it is not causally related to the color polymorphism in the Midas cichlid.

Although SCM can interact with Polycomb repressive complex 1 (PRC1) in vitro, biochemical studies have indicated that SCM is not a core constituent of PRC1 or PRC2. Nevertheless, SCM is just as critical for Drosophila Hox gene silencing as canonical subunits of these well-characterized PcG complexes. To address functional relationships between SCM and other PcG components, we have performed chromatin immunoprecipitation studies using cultured Drosophila Schneider line 2 (S2) cells and larval imaginal discs. We find that SCM associates with a Polycomb response element (PRE) upstream of the Ubx gene which also binds PRC1, PRC2, and the DNA-binding PcG protein Pleiohomeotic (PHO). However, SCM is retained at this Ubx PRE despite genetic disruption or knockdown of PHO, PRC1, or PRC2, suggesting that SCM chromatin targeting does not require prior association of these other PcG components. Chromatin immunoprecipitations (IPs) to test the consequences of SCM genetic disruption or knockdown revealed that PHO association is unaffected, but reduced levels of PRE-bound PRC2 and PRC1 were observed. We discuss these results in light of current models for recruitment of PcG complexes to chromatin targets.

    This paper assesses the variations in costs and length of stay for hip replacement cases in Austria, England, Estonia, Finland, France, Germany, Ireland, Poland, Spain and Sweden and examines the ability of national diagnosis-related group (DRG) systems to explain the variation in resource use against a set of patient characteristic and treatment specific variables. In total, 195,810 cases clustered in 712 hospitals were analyzed using OLS fixed effects models for cost data (n=125,698) and negative binominal models for length-of-stay data (n=70,112). The number of DRGs differs widely across the 10 European countries (range: 2-14). Underlying this wide range is a different use of classification variables, especially secondary diagnoses and treatment options are considered to a different extent. In six countries, a standard set of patient characteristics and treatment variables explain the variation in costs or length of stay better than the DRG variables. This raises questions about the adequacy of the countries' DRG system or the lack of specific criteria, which could be used as classification variables. Copyright © 2012 John Wiley & Sons, Ltd.

    Cross-cultural communication of "nuttiness" can be problematic because the underlying conceptual elements and words used to describe its features may be largely culture-dependent. The present study was conducted to understand similarities and dissimilarities in the concept of nuttiness and its actual perception in our model food system, soymilk, among similar (Korean and Chinese) and dissimilar (Western) food cultures. In total, 110 Koreans, 103 Chinese, and 93 English-speaking, Western consumers were recruited. Subjects were asked to provide a definition of nuttiness and generate examples of nutty and non-nutty foods. They also rated the intensity of the nuttiness of 8 soymilk samples. Sensory profiles of 8 soymilk samples were obtained using 9 trained panelists. Data from the definition task were processed through textual analysis. To identify sensory drivers, consumer ratings of perceived nuttiness intensity in soymilk were projected onto a sensory space constructed from the descriptive profiles of nuttiness. We found significant association between culture and usage of specific words (χ 2 70, 0.05 =155.8, pcultures. We found that although the abstract definition of nuttiness clearly demonstrated cross-cultural differences, sensory perception of nuttiness was almost identical across all groups. This suggests that cultural background influences verbalization of one's perception, but not the actual perception itself. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Root growth and morphology may play a core role in species-niche partitioning in highly diverse communities, especially along gradients of drought risk, such as that created along the secondary succession of tropical dry forests. We experimentally tested whether root foraging capacity, especially at depth, decreases from early successional species to old-growth forest species. We also tested for a trade-off between two mechanisms for delaying desiccation, the capacity to forage deeper in the soil and the capacity to store water in tissues, and explored whether successional groups separate along such a trade-off. We examined the growth and morphology of roots in response to a controlled-vertical gradient of soil water, among seedlings of 23 woody species dominant along the secondary succession in a tropical dry forest of Mexico. As predicted, successional species developed deeper and longer root systems than old-growth forest species in response to soil drought. In addition, shallow root systems were associated with high plant water storage and high water content per unit of tissue in stems and roots, while deep roots exhibited the opposite traits, suggesting a trade-off between the capacities for vertical foraging and water storage. Our results suggest that an increased capacity of roots to forage deeper for water is a trait that enables successional species to establish under the warm-dry conditions of the secondary succession, while shallow roots, associated with a higher water storage capacity, are restricted to the old-growth forest. Overall, we found evidence that the root depth-water storage trade-off may constrain tree species distribution along secondary succession.

    Markers for endothelial cells including Ulex europaeus 1 lectin, blood group A, B, and H, and the prostaglandin metabolite 6-keto-PGF1 alpha were evaluated in paraffin secretions from formalin-fixed benign and malignant vascular neoplasms using a variety of immunohistochemical techniques, and results compared with staining for factor VIII-related antigen. Staining for Ulex appeared more sensitive than factor VIII-related antigen in identifying poorly differentiated neoplasms including haemangiosarcomas and spindle cell proliferations in Kaposi's sarcoma. Staining for blood group related antigens correlated with blood group in all cases. Ulex europaeus 1 lectin was the only marker for endothelial cells in lymphangiomas.

    We examined whether a program combining cognitive-behavioural therapy (CBT), vestibular rehabilitation (VR) and psychoeducation is equally effective in improving psychometric measures in patients with dizziness independent of a balance deficit. Measures of patients with dizziness only (DO) were compared to those of patients also having a quantified balance deficit (QBD). 32 patients (23 female, 9 male) with persistent dizziness were analysed as 2 groups based on stance and gait balance control: those with QBD (pathological balance) or DO (normal balance). Dizziness Handicap Inventory (DHI) and Brief Symptom Inventory (BSI) questionnaires were used pre- and post-therapy to assess psychometric measures. Patients then received the same combination therapy in a group setting. The QBD group mean age was 60.6, SD 8.3, and DO group mean age 44.8, SD 12.1, years. Pre-therapy, questionnaire scores were pathological but not different between groups. Balance improved significantly for the QBD group (p=0.003) but not for the DO group. DHI and BSI scores improved significantly in the DO group (0.001balance control improving to near normal. Possibly, greater focus on phobic anxiety during the group therapy program would have improved psychological measures of QBD patient. Copyright © 2017 Elsevier Inc. All rights reserved.

    PURPOSE: To examine the long-term outcomes of a randomized trial comparing short (4 months; Arm 1) and long (8 months; Arm 2) neoadjuvant hormonal therapy before radiotherapy for localized prostate cancer. METHODS AND MATERIALS: Between 1997 and 2001, 276 patients were enrolled and the data from 261 were analyzed. The stratification risk factors were prostate-specific antigen level >20 ng\\/mL, Gleason score >\\/=7, and Stage T3 or more. The intermediate-risk stratum had one factor and the high-risk stratum had two or more. Staging was done from the bone scan and computed tomography findings. The primary endpoint was biochemical failure-free survival. RESULTS: The median follow-up was 102 months. The overall survival, biochemical failure-free survival. and prostate cancer-specific survival did not differ significantly between the two treatment arms, overall or at 5 years. The cumulative probability of overall survival at 5 years was 90% (range, 87-92%) in Arm 1 and 83% (range, 80-86%) in Arm 2. The biochemical failure-free survival rate at 5 years was 66% (range, 62-71%) in Arm 1 and 63% (range, 58-67%) in Arm 2. CONCLUSION: No statistically significant difference was found in biochemical failure-free survival between 4 months and 8 months of neoadjuvant hormonal therapy before radiotherapy for localized prostate cancer.

    We compared the genetic diversity and distance among six German draught horse breeds to wild (Przewalski's Horse), primitive (Icelandic Horse, Sorraia Horse, Exmoor Pony) or riding horse breeds (Hanoverian Warmblood, Arabian) by means of genotypic information from 30 microsatellite loci. The draught horse breeds included the South German Coldblood, Rhenish German Draught Horse, Mecklenburg Coldblood, Saxon Thuringa Coldblood, Black Forest Horse and Schleswig Draught Horse. Despite large differences in population sizes, the average observed heterozygosity (H(o)) differed little among the heavy horse breeds (0.64-0.71), but was considerably lower than in the Hanoverian Warmblood or Icelandic Horse population. The mean number of alleles (N(A)) decreased more markedly with declining population sizes of German draught horse breeds (5.2-6.3) but did not reach the values of Hanoverian Warmblood (N(A) = 6.7). The coefficient of differentiation among the heavy horse breeds showed 11.6% of the diversity between the heavy horse breeds, as opposed to 21.2% between the other horse populations. The differentiation test revealed highly significant genetic differences among all draught horse breeds except the Mecklenburg and Saxon Thuringa Coldbloods. The Schleswig Draught Horse was the most distinct draught horse breed. In conclusion, the study demonstrated a clear distinction among the German draught horse breeds and even among breeds with a very short history of divergence like Rhenish German Draught Horse and its East German subpopulations Mecklenburg and Saxon Thuringa Coldblood.

    Full Text Available Regression analysis is commonly used in genome-wide association studies (GWAS to test genotype-phenotype associations but restricts the phenotype to a single observation for each individual. There is an increasing need for analytic methods for longitudinally collected phenotype data. Several methods have been proposed to perform longitudinal GWAS for family-based studies but few methods are described for unrelated populations. We compared the performance of three statistical approaches for longitudinal GWAS in unrelated subjectes: (1 principal component-based generalized estimating equations (PC-GEE; (2 principal component-based linear mixed effects model (PC-LMEM; (3 kinship coefficient matrix-based linear mixed effects model (KIN-LMEM, in a study of single-nucleotide polymorphisms (SNPs on the duration of 4 courses of chemotherapy in 624 unrelated children with de novo acute myeloid leukemia (AML genotyped on the Illumina 2.5M OmniQuad from the COG studies AAML0531 and AAML1031.In this study we observed an exaggerated type I error with PC-GEE in SNPs with minor allele frequencies < 0.05, wheras KIN-LMEM produces more than expected type II errors. PC-MEM showed balanced type I and type II errors for the observed versus expected P-values in comparison to competing approaches. In general, a strong concordance was observed between the P-values with the different approaches, in particular among P-values < 0.01 where the between-method AUCs exceed 99%. PC-LMEM accounts for genetic relatedness and correlations among repeated phenotype measures, shows minimal genome-wide inflation of type I errors, and yields high power. We therefore recommend PC-LMEM as a robust analytic approach for GWAS of longitudinal data in unrelated populations.

    Metastasis size in melanoma sentinel lymph nodes (SLNs) is an emerging prognostic factor. Two European melanoma treatment trials include SLN metastasis diameters as inclusion criteria. Whilst diameter estimates are sensitive to the number of sections examined, the level of this bias is largely unknown. We performed a prospective multicentre study to compare the European Organisation for Research and Treatment of Cancer (EORTC) recommended protocol with a protocol of complete step-sectioning. One hundred and thirty-three consecutive SLNs from seven SLN centres were analysed by five central sections 50μm apart (EORTC Protocol) followed by complete 250μm step-sectioning. Overall, 29 patients (21.8%) were SLN-positive. The EORTC Protocol missed eight of these metastases (28%), one metastasis measuring less than 0.1mm in diameter, seven measuring between 0.1 and 1mm. Complete step-sectioning at 250μm intervals (Extensive Protocol) missed one metastasis (3%) that measured less than 0.1mm. Thirteen treatment courses (34%) performed if inclusion was based on the Combined Protocol would not be performed if assessed by the EORTC Protocol. Thus, 10 patients would be without completion lymph node dissection (EORTC MINITUB study), whilst three patients would not be eligible for anti-CTLA4 trial (EORTC protocol 18071). The corresponding number with the Extensive Protocol would be three; one patient for the MINITUB registration study and two patients for the anti-CTLA4 study. Examining SLNs by close central sectioning alone (EORTC Protocol) misses a substantial number of metastases and underestimates the maximum metastasis diameter, leading to important changes in patient eligibility for various treatment protocols.

    In the absence of large, prospective, placebo-controlled studies of longer duration, substantial evidence regarding the safety and risk of testosterone (T) therapy (TTh) with regard to cardiovascular (CV) outcomes can only be gleaned from observational studies. To date, there are limited studies comparing the effects of long-term TTh in men with hypogonadism who were treated or remained untreated with T, for obvious reasons. We have established a registry to assess the long-term effectiveness and safety of T in men in a urological setting. Here, we sought to compare the effects of T on a host of parameters considered to contribute to CV risk in treated and untreated men with hypogonadism (control group). Observational, prospective, cumulative registry study in 656 men (age: 60.7 ± 7.2 years) with total T levels ≤12.1 nmol/L and symptoms of hypogonadism. In the treatment group, men (n = 360) received parenteral T undecanoate (TU) 1000 mg/12 weeks following an initial 6-week interval for up to 10 years. Men (n = 296) who had opted against TTh served as controls. Median follow-up in both groups was 7 years. Measurements were taken at least twice a year, and 8-year data were analyzed. Mean changes over time between the 2 groups were compared by means of a mixed-effects model for repeated measures, with a random effect for intercept and fixed effects for time, group, and their interaction. To account for baseline differences between the 2 groups, changes were adjusted for age, weight, waist circumference, fasting glucose, blood pressure, and lipids. There were 2 deaths in the T-treated group, none was related to CV events. There were 21 deaths in the untreated (control) group, 19 of which were related to CV events. The incidence of death in 10 patient-years was 0.1145 in the control group (95% confidence interval [CI]: 0.0746-0.1756; P control group and none in the T-treated group. Long-term TU was well tolerated with excellent adherence suggesting a high level of

    To compare in a multicenter randomized controlled trial the benefits in terms of anxiety regulation of a 15-session single-component group intervention (SGI) based on support with those of a 15-session multiple-component structured manualized group intervention (MGI) combining support with cognitive-behavioral and hypnosis components. Patients with nonmetastatic breast cancer were randomly assigned at the beginning of the survivorship period to the SGI (n = 83) or MGI (n = 87). Anxiety regulation was assessed, before and after group interventions, through an anxiety regulation task designed to assess their ability to regulate anxiety psychologically (anxiety levels) and physiologically (heart rates). Questionnaires were used to assess psychological distress, everyday anxiety regulation, and fear of recurrence. Group allocation was computer generated and concealed till baseline completion. Compared with patients in the SGI group (n = 77), patients attending the MGI group (n = 82) showed significantly reduced anxiety after a self-relaxation exercise (P = .006) and after exposure to anxiety triggers (P = .013) and reduced heart rates at different time points throughout the task (P = .001 to P = .047). The MGI participants also reported better everyday anxiety regulation (P = .005), greater use of fear of recurrence-related coping strategies (P = .022), and greater reduction in fear of recurrence-related psychological distress (P = .017) compared with the SGI group. This study shows that an MGI combining support with cognitive-behavioral techniques and hypnosis is more effective than an SGI based only on support in improving anxiety regulation in patients with breast cancer.

    Full Text Available Objectives. Overactive bladder (OAB is a chronic disease, but comparative trials of anticholinergics, which are commonly used for treatment of OAB, have generally been performed for up to 12 weeks only. There is no comparative study of a long-term intervention. Methods. We conducted a 52-week prospective randomized comparative study to evaluate the efficacy and tolerability of two anticholinergics. Results. Forty-one Japanese patients with untreated OAB were randomly assigned to imidafenacin and solifenacin groups. There was no difference in OABSS and KHQ scores between the two groups, but the severity and incidence of adverse events caused by the anticholinergics showed increased differences between the groups with time. The severity of dry mouth and the incidence of constipation were significantly lower in the imidafenacin group (=0.0092 and =0.0013, resp.. Conclusions. This study is the first long-term trial to show differences in the properties of anticholinergics that were not detected in short-term studies. Since OAB is a chronic disease, we conclude that imidafenacin is preferable to solifenacin from a perspective of safety.

  5. A randomized, double-blind, multicenter, parallel group study to compare relative efficacies of the topical gels 3% erythromycin/5% benzoyl peroxide and 0.025% tretinoin/erythromycin 4% in the treatment of moderate acne vulgaris of the face.

    Combination treatments for acne vulgaris, such as Benzamycin (3% erythromycin/5% benzoyl peroxide) and Stievamycin (0.025% tretinoin/erythromycin 4%), reduce bacterial growth, which contributes to the inflammatory lesions typical of adolescent acne, and also decrease the epidermal cell compaction which may form the characteristic noninflammatory comedone. Both agents contain erythromycin to reduce the growth of Propionibacterium acnes in skin. Benzoyl peroxide has antibiotic activity as well as anticomedogenic properties. Tretinoin may increase the turnover of epidermal cells and loosen the cells compacted to form comedones. A combination preparation containing the two antibiotics may reduce the development of resistance; the combination preparation containing tretinoin and erythromycin will have an antibiotic effect as well as acting on differentiation. This multicenter, randomized, double-blind, parallel group study compared the effectiveness of 3% erythromycin/5% benzoyl peroxide and 0.025% tretinoin/erythromycin 4%, each applied twice daily in patients with moderate acne vulgaris. Overall physician and patient ratings of severity of acne symptoms were performed at baseline and at weeks 2, 4, 8, and 12. At baseline the two treatment groups had similar disease severity. The number of papules, pustules, and comedones was reduced in both treatment groups at week 12, and the reductions were not significantly different between the two comparators. Global physician rating of improvement was significantly higher in the 3% erythromycin/5% benzoyl peroxide group compared with the 0.025% tretinoin/erythromycin 4% group; however, there was no significant difference in global patient ratings between the two treatment groups. An aggregate score was produced, for both physician rating and patient rating, by adding up individual symptom severity ratings. Compared with 0.025% tretinoin/erythromycin 4%, 3% erythromycin/5% benzoyl peroxide provided significantly greater reduction

    CT-P13 (Remsima®, Inflectra®) is a biosimilar of the infliximab reference product (RP; Remicade®) and is approved in Europe and elsewhere, mostly for the same indications as RP. The aim of this study was to compare the 54-week efficacy, immunogenicity, pharmacokinetics (PK) and safety of CT-P13 with RP in patients with ankylosing spondylitis (AS), with a focus on patient-reported outcomes (PROs). This was a multinational, double-blind, parallel-group study in patients with active AS. Participants were randomized (1:1) to receive CT-P13 (5 mg/kg) or RP (5 mg/kg) at weeks 0, 2, 6 and then every 8 weeks up to week 54. To assess responses, standardized assessment tools were used with an intention-to-treat analysis of observed data. Anti-drug antibodies (ADAs), PK parameters, and safety outcomes were also assessed. Of 250 randomized patients (n = 125 per group), 210 (84.0 %) completed 54 weeks of treatment, with similar completion rates between groups. At week 54, Assessment of Spondylo Arthritis international Society (ASAS)20 response, ASAS40 response and ASAS partial remission were comparable between treatment groups. Changes from baseline in PROs such as mean Bath Ankylosing Spondylitis Disease Activity Index (BASDAI; CT-P13 -3.1 versus RP -2.8), Bath Ankylosing Spondylitis Functional Index (BASFI; -2.9 versus -2.7), and Short Form Health Survey (SF-36) scores (9.26 versus 10.13 for physical component summary; 7.30 versus 6.54 for mental component summary) were similar between treatment groups. At 54 weeks, 19.5 % and 23.0 % of patients receiving CT-P13 and RP, respectively, had ADAs. All observed PK parameters of CT-P13 and RP, including maximum and minimum serum concentrations, were similar through 54 weeks. The influence of ADAs on PK was similar in the two treatment groups. Most adverse events were mild or moderate in severity. There was no notable difference between treatment groups in the incidence of adverse events, serious adverse events

    Full Text Available The aims of this ex post facto study were to determine the comorbidity of personality disorders (PD with eating disorders (ED, to establish the prominent characteristics of eating disorders subtypes and to compare PDs appeared in patients with EDs with those in other clinical and normal samples. Using the International Personality Disorders Examination (IPDE, 84 outpatients with EDs were compared with 23 mentally disordered women and with 23 normative women. All the statistical analyses have been carried out using non-parametric analyses. 54.8% of ED sample met criteria for at least one PD compared to 21.7% of non-ED patients and to 8.7% of normative control group. The most common PDs in the ED group were the obsessivecompulsive, borderline and avoidant, without any differences among the EDs groups. More than a half of the subjects with anorexia nervosa and bulimia nervosa met the criteria for at least one PD and this was a specific characteristic of patients with an ED.

    In a randomized, parallel-group, single-center study in 42 healthy adults, the safety and pharmacokinetic parameters of an intravenous formulation of 18.75 and 37.5 mg diclofenac sodium (DFP-08) following single- and multiple-dose bolus administration were compared with diclofenac potassium 50 mg oral tablets. Mean AUC0-inf values for a 50-mg oral tablet and an 18.75-mg intravenous formulation were similar (1308.9 [393.0]) vs 1232.4 [147.6]). As measured by the AUC, DFP-08 18.75 mg and 37.5 mg demonstrated dose proportionality for extent of exposure. One subject in each of the placebo and DFP-08 18.75-mg groups and 2 subjects in the DFP-08 37.5-mg group reported adverse events that were considered by the investigator to be related to the study drug. All were mild in intensity and did not require treatment. Two subjects in the placebo group and 1 subject in the DFP-08 18.75-mg group reported grade 1 thrombophlebitis; no subjects reported higher than grade 1 thrombophlebitis after receiving a single intravenous dose. The 18.75- and 37.5-mg doses of intravenous diclofenac (single and multiple) were well tolerated for 7 days. Additional efficacy and safety studies are required to fully characterize the product. © 2015, The American College of Clinical Pharmacology.

    Full Text Available Background and Objectives: Emphasis is placed on the correction of reading the prayer as an important precept in Islamic culture, and it is essential to use an effective teaching method to promote the status of reading the prayers in youth. This study was conducted with the aim of comparing the effect of the methods of group teaching, personal (face-to-face teaching and using compact disc (CD on correcting the pronunciation and reading of the prayer in the students of Qom University of Medical Sciences in 2011.Methods: This semi-experimental study was done on the students of the Faculty of Nursery and Midwifery of Qom University of Medical Sciences. The samples were randomly assigned into three groups, and the number of students in each group was 22. A checklist of reading mistakes was completed before the intervention, and then, teaching content was given to them in the form of group and face-to-face teaching and CD. In the following, reading mistakes of the students’ prayer were recorded one month after intervention. Data was analyzed using descriptive statistics, and Kruskal–Wallis and Wilcoxon tests at a significance level of p0.05.Conclusion: Based on the findings of this study, the effect of teaching methods of group, personal, and CD was the same in correcting the students’ reading of the prayer. Therefore, it is suggested that considering the students’ interest and current circumstances, various methods could be used for correction of the students’ reading of the prayer.

    A placebo-controlled, randomized, double-blind, parallel-group, comparative, multicenter study was conducted to investigate the efficacy and safety of benzoyl peroxide (BPO) gel, administrated once daily for 12 weeks to Japanese patients with acne vulgaris. Efficacy was evaluated by counting all inflammatory and non-inflammatory lesions. Safety was evaluated based on adverse events, local skin tolerability scores and laboratory test values. All 609 subjects were randomly assigned to receive the study products (2.5% and 5% BPO and placebo), and 607 subjects were included in the full analysis set, 544 in the per protocol set and 609 in the safety analyses. The median rates of reduction from baseline to the last evaluation of the inflammatory lesion counts, the primary end-point, in the 2.5% and 5% BPO groups were 72.7% and 75.0%, respectively, and were significantly higher than that in the placebo group (41.7%). No deaths or other serious adverse events were observed. The incidences of adverse events in the 2.5% and 5% BPO groups were 56.4% and 58.8%, respectively; a higher incidence than in the placebo group, but there was no obvious difference between the 2.5% and 5% BPO groups. All adverse events were mild or moderate in severity. Most adverse events did not lead to study product discontinuation. The results suggested that both 2.5% and 5% BPO are useful for the treatment of acne vulgaris. © 2017 The Authors. The Journal of Dermatology published by John Wiley & Sons Australia, Ltd.

    Background Group exercise programs for older adults often exclude the timing and coordination of movement. Stakeholder involvement in the research process is strongly encouraged and improves the relevance and adoption of findings. We describe stakeholder involvement in the design of a clinical trial of a group-based exercise program that incorporates timing and coordination of movement into the exercises. Methods The study was a cluster randomized, single-blind intervention trial to compare the effects on function, disability and mobility of a standard group exercise program and the “On the Move” group exercise program in older adults residing in independent living facilities and senior apartment buildings, and attending community centers. Exercise classes were twice weekly for 12 weeks delivered by study exercise leaders and facility activity staff personnel. Outcomes The primary outcomes function, disability and mobility were assessed at baseline and post-intervention. Function and disability were assessed using the Late Life Function and Disability Instrument, and mobility using the Six-Minute Walk Test and gait speed. Stakeholders Patient and provider stakeholders had significant input into the study aims, design, sample, intervention, outcomes and operational considerations. Summary A community-based exercise program to improve walking can be developed to address both investigator identified missing components in current exercise to improve walking and stakeholder defined needs and interest for the activity program. Involvement of stakeholders substantially improves the relevance of research questions, increases the transparency of research activities and may accelerate the adoption of research into practice.

    The aim of this study was to compare the tolerability and efficacy of once-daily travoprost 0.004% versus latanoprost 0.005% for 6 weeks followed by 6 weeks of once-daily travoprost 0.004% in decreasing intraocular pressure (IOP) in patients with open-angle glaucoma (OAG) or ocular hypertension (OH). This multicenter, randomized, doublemasked, active-controlled, parallel-group trial was conducted at 32 centers across Latin America. Patients aged > or =18 years with OAG or OH were randomly assigned to receive topical travoprost 0.004% or latanoprost 0.005% 1 drop QD (9 PM) for 6 weeks (masked phase). At 6 weeks, all patients were assigned to receive open-label travoprost 0.004% 1 drop QD (9 PM) for 6 additional weeks (open-label phase). Study visits were scheduled at weeks 1, 2, 4, 6, 8, and 12. At each study visit, IOP was measured at 5 PM (+/-1 hour; approximately 20 hours after study drug administration). IOP changes from baseline were combined (pooled) from the 1-, 2-, 4-, and 6-week data to provide a comparison between the 2 treatment groups. Ocular adverse events (AEs) were monitored using slit-lamp examination. A total of 302 patients were enrolled (travoprost group, 155 patients; latanoprost group, 147 patients). The mean (SD) age of the travoprost group was 61.9 (10.6) years; 60.6% were female; and 47.1% were white. The mean (SD) age of the latanoprost group was 60.5 (12.4) years; 62.6% were female; and 49.0% were white. Mean IOP values were not significantly different between the travoprost and latanoprost groups at baseline (24.7 vs 24.2 mm Hg) or 6 weeks; however, the between-group difference in reductions from baseline in pooled IOP during the masked phase of the study was statistically significant (-8.3 vs -7.5 mm Hg; P = 0.009). At weeks 6 and 12, mean lOP levels were 16.1 and 16.2 mm Hg, respectively, in the travoprost group and 16.4 and 16.1 mm Hg in the group that was switched from latanoprost to travoprost (all, P = NS). The most common ocular AEs

    Full Text Available Research on comparative efficаcy and tolerability of monotherapy with Depakine chronosphere, drugs of Carbamazepine group with extended release and oxcarbazepine in symptomatic and cryptogenic focal epilepsy has been conducted at Svt. Luka’s Institute of Child Neurology and Epilepsy (ICNE (Moscow. This retrospective study covers a random sample of patients treated in ICNE in the period from December 1, 2013 to September 1, 2014.  The study included 131 patients aged 1 to 18 years with symptomatic and cryptogenic focal epilepsy receiving treatment with one of the study drugs in monotherapy: group 1 – monotherapy with Depakine chronosphere (n = 56; group 2 – monotherapy with drugs of carbamazepine group with extended release (n = 55; group 3 – monotherapy with oxcarbazepine (trileptal (n = 20. The obtained results allow us to conclude that the effectiveness of Depakin chronosphere, carbamazepine with extended release and oxcarbazepine in monotherapy of symptomatic and cryptogenic focal epilepsy was comparable (statistically significant differences in efficacy were not found. However, carbamazepine was awarded the highest frequency of seizures aggravation. Drugs showed approximately same tolerability (statistically significant differences in tolerability were not found. However, withdrawal of the drug due to side effects was the rarest in Depakine (3.5 %, and withdrawal due to intolerance was higher in carbamazepine and oxcarbazepine (5 and 10 % respectively. Depakinum and oxcarbazepine had the best results in the blocking of pathological activity on the electroencephalogram, whereas carbamazepine was clearly inferior to them. In this regard, complete clinical-electroencephalographic remission (lasting 12 months or more was achieved under treatment of Depakine chromosphere in 21.5 % of cases, oxcarbazepi on therapy for 12 months was similar in all study drugs. Considering that the objective of epilepsy treatment is to achieve complete

    The American College of Surgeons Oncology Group trial Z0011 was a prospective, randomized, multicenter trial comparing overall survival between patients with positive sentinel lymph nodes (SLNs) who did and did not undergo axillary lymph node dissection (ALND). The current study compares complications associated with SLN dissection (SLND) plus ALND, versus SLND alone. From May 1999 to December 2004, 891 patients were randomly assigned to SLND + ALND (n = 445) or SLND alone (n = 446). Information on wound infection, axillary seroma, paresthesia, brachial plexus injury (BPI), and lymphedema was available for 821 patients. Adverse surgical effects were reported in 70% (278 of 399) of patients after SLND + ALND and 25% (103 of 411) after SLND alone (P alone group. At 1 year, lymphedema was reported subjectively by 13% (37 of 288) of patients after SLND + ALND and 2% (six of 268) after SLND alone (P alone. Lymphedema was more common after SLND + ALND but was significantly different only by subjective report. The use of SLND alone resulted in fewer complications.

    200 cancer patients who were due to receive fractionated chemotherapy (cisplatin greater than or equal to 15, ifosfamide greater than or equal to 1.2 or etoposide greater than or equal to 120, all mg/m2 per day) for 5 days, entered a multicentre study. Patients were randomised single-blind to receive either prophylactic intravenous granisetron (40 micrograms/kg) or alizapride (4 mg/kg followed by 4 mg/kg at 4 and 8 h post-treatment) plus dexamethasone 8 mg. Granistron was superior to the combination in preventing nausea and vomiting (54% vs. 43% complete responders). The differences were in the cisplatin-treated group. The time to first episode of moderate to severe nausea was significantly longer in the granisetron group (P = 0.03). Dosing with granisetron was more simple, with over 85% of patients requiring only a single prophylactic dose. Fewer patients receiving granisetron experienced adverse events (48% vs. 62%, P = 0.047). The frequency of constipation was, as expected, significantly higher in the granisetron group. Extrapyramidal effects, which were not noted by any granisetron patient, occurred in 5.3% of comparator patients.
