    Full Text Available This cross-sectional study assessed risk factors for dental fluorosis (DF among 8- to 12-year-old children in southern Brazil. Children attending 20 schools were randomly selected (n = 1,196. They were interviewed and their parents answered a questionnaire that was sent home. Prevalence of DF was 8.53% (modified Dean’s criteria, and the prevalence of severe DF was 0.17%. The results of multiple logistic regression analyses indicated that DF was associated with a higher frequency of tooth brushing and with initial use of fluoride toothpaste at the emergence of the first tooth. DF does not constitute a public health problem in southern Brazil.

    Full Text Available Little is known about stroke patients’ awareness about the warning signs of stroke and its therapeutic time window in Brazil. Method We interviewed consecutive patients with acute stroke admitted to a terciary public hospital in Brazil. Data collected included demographics, mode of arrival, National Institutes of Health Stroke Scale (NIHSS scores and knowledge of stroke warning signs and therapeutic time window. Early arrival was defined as within 4.5 hours of symptoms onset. Results Although 66.2% of patients knew the warning signs of stroke, only 7.8% reported to know that stroke had a limited therapeutic time window. Stroke severity measured by the NIHSS was independently associated with early arrival, but not knowledge of stroke signs and symptoms. Conclusion Knowledge about stroke symptoms was not a predictor of early arrival.

    Full Text Available Objective: To estimate the prevalence of obesity and overweight and associated factors in indigenous people of the Jaguapiru village in Central Brazil. Methods: We conducted a population-based cross-sectional study between January 2009 and July 2011 in the adult native population of the Jaguapiru village, Central Brazil. Sociodemographic and lifestyle data were obtained; anthropometric measures, arterial blood pressure, and blood glucose were measured. The independent variables were tested by Poisson regression, and the interactions between them were analyzed. Results: 1,608 indigenous people (982 females, mean age 37.7 ± 15.1 years were included. The prevalence of obesity was 23.2% (95% CI 20.9-25.1%. Obesity was more prevalent among 40- to 49-year-old and overweight among 50- to 59-year-old persons. Obesity was positively associated with female sex, higher income, and hypertension. Among indigenous people, interactions were found with hypertension and sedentary lifestyle - hypertension in males and sedentary lifestyle in females. Conclusions: The prevalence of obesity and overweight in indigenous people of the Jaguapiru village is high. Males as well as hypertensive and higher family income individuals have higher rates. Sedentary lifestyle and hypertension leverage the rates of obesity. Prevention and adequate public health policies can be critical for the control of excess weight and its comorbidities among Brazilian indigenous people.

    The aim of this cross-sectional study was to evaluate the prevalence of oral mucosal lesions, and their risk indicators in adult Kiriri Indians from Northeast Brazil. Clinical oral examination was performed on a representative sample of 223 Indians (age ≥ 19 years). A systematic evaluation of lips, labial mucosa and sulcus, commissures, buccal mucosa and sulcus, gingiva and alveolar ridge, tongue, floor of the mouth, and soft and hard palate was performed. Bivariate analysis was conducted to assess associations between mucosal conditions and age, gender, income, educational level, diabetic status, and smoking status. Mucosal lesions were found in 50 participants (22.4%). The most prevalent lesions were fistulae (6.2%) and traumatic ulcers (4.48%). Oral mucosal was associated with higher age (≥ 35 years; odds ratio [OR] = 1.99, 95% confidence interval [CI]: 1.05-3.76, P = 0.03) and lower education level (Mucosal conditions are prevalent in Kiriri Indians and the presence of mucosal lesions is associated with advanced age and lower education. A public health program aimed at preventing and treating mucosal lesions and targeted toward the high-risk group is vital to improve the oral health status of this population. PMID:25501053

    Full Text Available In Brazil, leprosy is endemic and concentrated in high-risk clusters. Internal migration is common in the country and may influence leprosy transmission and hamper control efforts. We performed a cross-sectional study with two separate analyses evaluating factors associated with migration in Brazil’s Northeast: one among individuals newly diagnosed with leprosy and the other among a clinically unapparent population with no symptoms of leprosy for comparison. We included 394 individuals newly diagnosed with leprosy and 391 from the clinically unapparent population. Of those with leprosy, 258 (65.5% were birth migrants, 105 (26.6% were past five-year migrants, and 43 (10.9% were circular migrants. In multivariate logistic regression, three independent factors were found to be significantly associated with migration among those with leprosy: (1 alcohol consumption, (2 separation from family/friends, and (3 difficulty reaching the healthcare facility. Separation from family/friends was also associated with migration in the clinically unapparent population. The health sector may consider adapting services to meet the needs of migrating populations. Future research is needed to explore risks associated with leprosy susceptibility from life stressors, such as separation from family and friends, access to healthcare facilities, and alcohol consumption to establish causal relationships.

    Full Text Available A cross-sectional study was conducted on HIV-infected adults being treated with antiretroviral drugs at a reference service in Southern Brazil. Participants answered a sociodemographic questionnaire and were tested by scales assessing sociocognitive variables. Adherence to treatment was assessed by a self-report inventory developed for the study. Clinical information was obtained from the patients' records. Significance tests were conducted using univariate logistic regressions followed by multivariate logistic regression analysis. A total of 195 patients participated in the study and 56.9% of them reported > or = 95% adherence on the previous two days. In univariate analysis, the odds of adherence increased with self-efficacy (a person's conviction that he/she can successfully execute the behavior required to produce a certain desired outcome in taking medications as prescribed (OR = 3.50, 95% CI 1.90-6.55, and decreased with perception of negative affect and physical concerns (OR = 0.71, 95% CI 0.53-0.95. The odds were lower for taking antiretroviral medications >4 times a day (OR = 0.44, 95% CI 0.20-0.94 and higher for patients with 8 years of schooling (OR = 2.28, 95% CI 1.12-4.66. In the multivariate analysis, self-efficacy (OR = 3.33, 95% CI 1.69-6.56 and taking medication >4 times a day (OR = 0.34, 95% CI 0.14-0.80 were independently associated with adherence. Self-efficacy was the most important predictor of adherence, followed by number of times antiretroviral medication was taken per day. Among sociodemographic and clinical variables, only the number of years of schooling was associated with adherence. Motivational interventions based on self-efficacy may be useful for increasing treatment adherence.

    Full Text Available OBJECTIVES: Patients with mental illness are more exposed to violence than the general population. This study assessed factors associated with lifetime physical violence against these patients stratified by sex in Brazil. METHODS: This is a National cross-sectional multicenter study with a representative sample of 2,475 patients randomly selected from 26 public mental health services. Logistic regression was used to evaluate factors associated with physical violence and crude (OR and adjusted odds ratios (aOR with 95% confidence interval were estimated. Statistical level considered was 0.05. RESULTS: The prevalence of lifetime physical violence against mental patients was similar for women (57.6% and men (57.8%. Physical violence against women was independently associated with: previous psychiatric hospitalizations (aOR = 2.09, lifetime STD (aOR = 1.75, lifetime alcohol consumption (aOR = 1.59, age of sexual debut (< 16 y.o. (aOR = 1.40, lifetime sex under alcohol/drugs use (aOR = 2.08, having received/offered money for sex (aOR = 1.73 and lifetime incarceration (aOR = 1.69. Among men, associated factors were: age (18-40 y.o. (aOR = 1.90, history of homelessness (aOR = 1.71, previous psychiatric hospitalization (aOR = 1.39, lifetime STD (aOR = 1.52, lifetime alcohol consumption (aOR = 1.41, lifetime use of marijuana or cocaine (aOR = 1.54, having received/offered money for sex (aOR = 1.47, lifetime history of incarceration (aOR = 2.07. DISCUSSION: The prevalence of physical violence in this population was high for both sexes. Although there were similar factors independently associated with physical violence among men and women, there are important differences, such as age of sexual debut and lifetime sex under alcohol/drugs use for women, but not for men, while younger age, history of homelessness, and lifetime use of marijuana or cocaine were associated factors for men only.

    Full Text Available Abstract Background The adoption of health-related behaviors is an important part of adolescence. This study examined the prevalence and correlates of the isolated and simultaneous presence of behavioral risk factors for cardiovascular health (BRFCH among adolescents in Curitiba, Southern Brazil. Methods A cross-sectional study was performed with 1,628 adolescents (aged 11-17.9 years, 52.5% males that were randomly selected from 44 public schools. Self-report instruments were used to assess the variables. Six BRFCH were analyzed: insufficiently active, excessive TV watching, current alcohol and tobacco use, daily soft drinks consumption and inadequate fruit and vegetable consumption. Sociodemographic and behavioral variables were studied as possible correlates of the presence of BRFCH. Results The BRFCH with the highest prevalence were insufficiently active (50.5%, 95% confidence interval [95% CI]: 48.0-52.9 and daily soft drinks consumption (47.6%, 95% CI: 45.1-50.0. Approximately 30% of the adolescents presented three or more BRFCH simultaneously. Girls, adolescents who did not participate in organized physical activity, and who used computer/video games daily were the main high-risk subgroups for insufficiently active. Boys and those who used computer/video games daily were the high-risk subgroups for daily soft drinks consumption. For excessive TV watching, we identified to be at risk those who were from a high economic class, unemployed, and who used computer/video games daily. For current alcohol use, we identified older adolescents, who were from a high economic class and who worked to be at risk. Older adolescents, who worked and who spent little active time during a physical education class were the high-risk subgroups for current tobacco use. For inadequate fruit and vegetable consumption, we identified those who did not participate in organized physical activity to be at risk. Older adolescents, who were from a high economic class

    Full Text Available Abstract Background The increase in overall rates of cesarean sections (CS in Brazil causes concern and it appears that multiple factors are involved in this fact. In 2009, undergraduate students in the first and final years of medical school at the University of Santa Catarina answered questionnaires regarding their choice of mode of delivery. The aim of the study was to evaluate whether the education process affects decision-making regarding the waay of childbirth preferred by medical students. Methods A cross-sectional, quantitative study was conducted based on data obtained from questionnaires applied to medical students. The questions addressed four different scenarios in childbirth, as follows: under an uneventful pregnancy; the mode of delivery for a pregnant woman under their care; the best choice as a healthcare manager and lastly, choosing the birth of their own child. For each circumstance, there was an open question to explain their choice. Results A total of 189 students answered the questionnaires. For any uneventful pregnancy and for a pregnant woman under their care, 8.46% of the students would opt for CS. As a healthcare manager, only 2.64% of the students would recommend CS. For these three scenarios, the answers of the students in the first year did not differ from those given by students in the sixth year. In the case of the student’s own or a partner’s pregnancy, 41.4% of those in the sixth year and 16.8% of those in the first year would choose a CS. A positive association was found between being a sixth year student and a personal preference for CS according to logistic regression (OR = 2.91; 95%CI: 1.03–8.30. Pain associated with vaginal delivery was usually the reason for choosing a CS. Conclusions A higher number of sixth year students preferred a CS for their own pregnancy (or their partner’s compared to first year students. Pain associated with vaginal delivery was the most common reason given for haven chosen

    Full Text Available Abstract Background Hepatitis C chronic liver disease is a major cause of liver transplant in developed countries. This article reports the first nationwide population-based survey conducted to estimate the seroprevalence of HCV antibodies and associated risk factors in the urban population of Brazil. Methods The cross sectional study was conducted in all Brazilian macro-regions from 2005 to 2009, as a stratified multistage cluster sample of 19,503 inhabitants aged between 10 and 69 years, representing individuals living in all 26 State capitals and the Federal District. Hepatitis C antibodies were detected by a third-generation enzyme immunoassay. Seropositive individuals were retested by Polymerase Chain Reaction and genotyped. Adjusted prevalence was estimated by macro-regions. Potential risk factors associated with HCV infection were assessed by calculating the crude and adjusted odds ratios, 95% confidence intervals (95% CI and p values. Population attributable risk was estimated for multiple factors using a case–control approach. Results The overall weighted prevalence of hepatitis C antibodies was 1.38% (95% CI: 1.12%–1.64%. Prevalence of infection increased in older groups but was similar for both sexes. The multivariate model showed the following to be predictors of HCV infection: age, injected drug use (OR = 6.65, sniffed drug use (OR = 2.59, hospitalization (OR = 1.90, groups socially deprived by the lack of sewage disposal (OR = 2.53, and injection with glass syringe (OR = 1.52, with a borderline p value. The genotypes 1 (subtypes 1a, 1b, 2b and 3a were identified. The estimated population attributable risk for the ensemble of risk factors was 40%. Approximately 1.3 million individuals would be expected to be anti-HCV-positive in the country. Conclusions The large estimated absolute numbers of infected individuals reveals the burden of the disease in the near future, giving rise to costs for the health care

  18. Elliptical cross section fuel rod study II

    International Nuclear Information System (INIS)

    In this paper it is continued the behavior analysis and comparison between cylindrical fuel rods of circular and elliptical cross sections. Taking into account the accepted models in the literature, the fission gas swelling and release were studied. An analytical comparison between both kinds of rod reveals a sensible gas release reduction in the elliptical case, a 50% swelling reduction due to intragranular bubble coalescence mechanism and an important swelling increase due to migration bubble mechanism. From the safety operation point of view, for the same linear power, an elliptical cross section rod is favored by lower central temperatures, lower gas release rates, greater gas store in ceramic matrix and lower stored energy rates.

    This study aims to describe the types of intrafamilial violence perpetrated against children according to living conditions, family factors, and child characteristics, and to identify the association between types of intrafamilial violence and asthma symptoms in atopic and non-atopic children. A cross-sectional study was carried out with 1,370 caregivers as part of the Social Changes, Asthma and Allergy in Latin America (SCAALA) study, conducted in 2006 in Brazil. The study population was selected by random sampling. The main outcome measures were atopic and non-atopic asthma. We investigate the association between intrafamilial violence and asthma symptoms in atopic and non-atopic children. A backward multivariate logistic polytomous regression was performed to verify the main association. Nonviolent discipline (NVD) and maltreatment nonviolent discipline (MNVD) were positively associated with non-atopic asthma symptoms (NVD: odds ratio (OR)=1.95/95% confidence interval (CI)=1.17-3.25; MNVD: OR=1.95/95% CI=1.19-3.20). However, for the most severe intrafamilial violence, this association was not found after control of potential confounders. This study demonstrates the effect of types of intrafamilial violence on non-atopic asthma. Intrafamilial violence against children represents one more component in the determination of non-atopic asthma in Latin America. PMID:26149733

    Full Text Available Background: Studies assessing the prevalence of oral lesions in children and adolescents, particularly in gingiva are scarce in the literature. The aim of the study was to describe the distribution of gingival proliferative lesions based on clinical and histopathological diagnoses in children and adolescents. Materials and Methods: A review of clinical charts of children and adolescents aged between 0 and 18 years old, admitted to the Oral Medicine Outpatient Unit, of Universidade Federal do Paraná, for 15 years (1994–2009 was performed. Results: Six hundred and sixty-nine out of 5,129 patients treated during this period were aged between 0 and 18 years old, and 45 of these had gingival lesions. The largest number of lesions was observed between 11 and 16 years old. The majority of the patients were referred by Curitiba's public health system. Pyogenic granuloma was the most frequent lesion (19 = 42.2%, followed by peripheral giant cell lesion (11 = 24.4%, gingival fibromatosis (10 = 22.2%, and peripheral ossifying fibroma (5 = 11.1%. Conclusion: Gingival proliferative lesions can show similar clinical characteristics. Appropriate clinical and histopathological diagnoses are necessary to guide the healthcare professional to establish the adequate treatment and to estimate the risk of recurrence.

    Full Text Available We evaluated the DMFT (decayed, missing and filled teeth index and the prevalence of candidiasis, linear gingival erythema, oral hairy leukoplakia, herpes simplex, aphthous ulcers, Kaposi's sarcoma and lymphoma, as well as the association with TCD4 count, viral load (VL and antiretroviral therapy (ART in 140 HIV-infected adult individuals. A standardized examination to determine the DMFT index and the presence of oral lesions was conducted. Demographic data, TCD4 count and use of ART were obtained from medical records. A high number of decayed teeth detected among patients undergoing ART resulted in a mean DMFT of 16.9 teeth. It was observed that 24.2% of the individuals had at least one oral lesion. Candidiasis was the most frequent lesion and was associated with the TCD4 count. Oral hairy leukoplakia was associated with an increased VL. Regular use of ART was inversely associated with the occurrence of lesions. Overall, the studied population showed low prevalence of oral lesions and high DMFT index. The use of ART seems to reduce the occurrence of these lesions. Higher TCD4 count and a lower VL were associated with an improved oral health status in HIV + individuals

    The pelvic floor (PF) provides support to all pelvic organs, as well as appropriately closure/opening mechanism of the urethra, vagina, and anus. Therefore, it is likely that female athletes involved in high-impact and in strong-effort activities are at risk for the occurrence of urinary incontinence (UI). This study aimed to investigate the occurrence of UI and other PF dysfunctions (PFD) [anal incontinence (AI), symptoms of constipation, dyspareunia, vaginal laxity, and pelvic organ prolapse] in 67 amateur athletes (AT) compared with a group 96 of nonathletes (NAT). An ad hoc survey based on questions from reliable and valid instruments was developed to investigate the occurrence of PFD symptoms. The risk of UI was higher in AT group (odds ratio: 2.90; 95% CI: 1.50-5.61), mostly among artistic gymnastics and trampoline, followed by swimming and judo athletes. Whereas, AT group reported less straining to evacuate (OR: 0.46; 95% CI: 0.22-0.96), manual assistance to defecate (OR: 0.24; 95% CI: 0.05-1.12), and a higher stool frequency (OR: 0.29; 95% CI: 0.13-0.64) than NAT group. The occurrence of loss of gas and sexual symptoms was high for both groups when compared with literature, although with no statistical difference between them. Pelvic organ prolapse was only reported by nonathletes. Athletes are at higher risk to develop UI, loss of gas, and sexual dysfunctions, either practicing high-impact or strong-effort activities. Thus, pelvic floor must be considered as an entity and addressed as well. Also, women involved in long-term high-impact and strengthening sports should be advised of the impact of such activities on pelvic floor function and offered preventive PFD strategies as well.

    Full Text Available Abstract Background Population variation in the duration and amount of menstrual bleeding has received little attention in the literature. This study describes these characteristics and investigates the distribution of self-perceived amount of menstrual bleeding according to socio-demographic, behavioral, and reproductive characteristics. Methods A community-based cross-sectional study was conducted among 18-45 years old women users of the 31 primary health care (PHC facilities in Pelotas city (Brazil. Interviews with structured questionnaire were carried out in the waiting rooms during two work shifts. Heaviness of menstrual bleeding was determined through the answer to the question: "Usually how much blood do you lose in every period?" Crude and adjusted analyses through Poisson regression took into account the aggregation per PHC facility. Results A total of 865 women were enrolled. Prevalence of heavy menstrual flow was 35.3% (95% CI 32.1-38.6%. In adjusted analyses, heavy menstrual bleeding was higher among the older, less educated and obese women, with higher number of pregnancies and who reported longer menstrual periods, extra-menstrual bleeding and clots in the flow. Use of hormonal contraceptive methods was protective against heavy menses. Conclusion Heavy menstrual bleeding is highly prevalent at the community level, and is associated with socio-demographic and anthropometric women's characteristics, as well as with duration of menstruation, extra-bleeding and presence of clots.

    Depression is the most common psychiatric co-morbidity among people living with HIV (PLHIV), with prevalence rates ranging from 25% to 36%. Depression impacts negatively upon adherence and response to combined antiretroviral therapy (CART) and the transmission of HIV infection through increased sexually risky behavior. This cross-sectional study presents data from a reference HIV-outpatient service in Dourados (Brazil) that evaluated the association between depressive symptoms, health-related quality of life, and clinical, socioeconomic, and demographic factors in newly diagnosed HIV/AIDS patients. Using the Beck Depression Inventory (BDI), the prevalence of depressive symptoms was 61% with a predominance of self-deprecating and cognitive-affective factors. Depressive symptoms were associated with lower income (p=0.019) and disadvantaged social class (p=0.005). Poorer quality of life was related to depressive symptoms (p<0.0001), low educational level (p=0.05), and lower income (p=0.03). These data suggest that socioeconomic factors, including level of income and education, are mediating the risk of depression and poor quality of life of PLHIV. Possible explanations for this effect are discussed, including the possible role of stigma. PMID:25741909

    Full Text Available Abstract Background Music is ever present in our daily lives, establishing a link between humans and the arts through the senses and pleasure. Sound technicians are the link between musicians and audiences or consumers. Recently, general concern has arisen regarding occurrences of hearing loss induced by noise from excessively amplified sound-producing activities within leisure and professional environments. Sound technicians' activities expose them to the risk of hearing loss, and consequently put at risk their quality of life, the quality of the musical product and consumers' hearing. The aim of this study was to measure the prevalence of high frequency hearing loss consistent with noise exposure among sound technicians in Brazil and compare this with a control group without occupational noise exposure. Methods This was a cross-sectional study comparing 177 participants in two groups: 82 sound technicians and 95 controls (non-sound technicians. A questionnaire on music listening habits and associated complaints was applied, and data were gathered regarding the professionals' numbers of working hours per day and both groups' hearing complaint and presence of tinnitus. The participants' ear canals were visually inspected using an otoscope. Hearing assessments were performed (tonal and speech audiometry using a portable digital AD 229 E audiometer funded by FAPESP. Results There was no statistically significant difference between the sound technicians and controls regarding age and gender. Thus, the study sample was homogenous and would be unlikely to lead to bias in the results. A statistically significant difference in hearing loss was observed between the groups: 50% among the sound technicians and 10.5% among the controls. The difference could be addressed to high sound levels. Conclusion The sound technicians presented a higher prevalence of high frequency hearing loss consistent with noise exposure than did the general population, although

    Full Text Available Objectives: To investigate the sociodemographic and clinical profile of patients receiving treatment at a specialized service for children and adolescents with eating disorders (ED in São Paulo, Brazil, and to compare data with the relevant literature. Methods: This cross-sectional study assessed male and female patients with ED up to 18 years of age. All data were collected upon admission. Results: A total of 100 subjects were assessed. Mean age was 15.41±0.18 years, and mean age at ED onset was 13.5±0.19 years. Mean disease duration was 21.06 ±1.67 months. Of the total sample, 82% of the patients were female, 84% were Caucasian, 64% came from A and B economic tiers. Moreover, in 60% ED started at 14 years of age or less, and 74% had psychiatric comorbidities. Anorexia nervosa was the most prevalent diagnosis (43%. Hospitalized patients had lower body mass index, longer ED duration, and more severe scores on the Children's Global Assessment Scale than outpatients (p < 0.05. Conclusions: Our young Brazilian patients with ED present epidemiological and symptomatic characteristics very similar to those found in the scientific literature, including a high prevalence of psychiatric comorbidities. The higher frequency of full syndrome ED, the predominance of cases with an early onset, the delay in beginning specialized treatment, and the more severe state of inpatients provide grounds for concern because these factors differ from what has been reported in reference studies and indicate greater ED severity.

    Full Text Available Abstract Background Vitamin D deficiency has been associated with a multitude of disorders including diabetes, defective insulin secretion as well as rickets and poor bone health. Vitamin D is also a concern during childhood and adolescence and has been reported in girls from South Brazil. We determined the prevalence of vitamin D deficiency in girls from South Brazil and investigated whether the genotypic distribution of the BsmI, ApaI and TaqI polymorphisms of the VDR gene and their haplotypes were associated with vitamin D levels. Methods Cross-sectional study including 234 apparently healthy girls aged 7 to 18 years. Height and weight were measured for calculation of body mass index (BMI percentiles for age. Plasma levels of 25-hydroxyvitamin D [25(OHD] were assessed. Participants were genotyped for ApaI (rs7975232, TaqI (rs731236, and BsmI (rs1544410 SNPs. Results The median and interquartile range (25-75% of BMI percentile was 62.0 (33.3 – 84.9. The frequency of overweight/obesity was 24.9%. Circulating levels of 25(OHD (≥ 30 ng/mL were adequate in 9.4%; insufficient in 54.3% (20–29 ng/mL; and deficient in 36.3% (vs. GA + AA, two-tailed Student’s t-test p vs. GT + TT, two-tailed Student’s t-test p = 0.031 and TaqI (TT vs. TC + CC, two-tailed Student’s t-test p = 0.005 SNPs and the GGT haplotype (two-tailed Student’s t-test p = 0.036 were significantly associated with lower 25(OHD levels. Conclusions 25-hydroxyvitamin D deficiency and insufficiency were highly prevalent in this sample. The BsmI, ApaI and TaqI wild variants of the VDR gene, as well as the GGT haplotype, were associated with lower vitamin D levels, suggesting that VDR gene polymorphisms could be linked to higher susceptibility to vitamin D deficiency in a sub-population of children and adolescents.

    Full Text Available Abstract Background The success of HPV vaccination programs will require awareness regarding HPV associated diseases and the benefits of HPV vaccination for the general population. The aim of this study was to assess the level of awareness and knowledge of human papillomavirus (HPV infection, cervical cancer prevention, vaccines, and factors associated with HPV awareness among young women after birth of the first child. Methods This analysis is part of a cross-sectional study carried out at Hospital Maternidade Leonor Mendes de Barros, a large public maternity hospital in Sao Paulo. Primiparous women (15-24 years who gave birth in that maternity hospital were included. A questionnaire that included questions concerning knowledge of HPV, cervical cancer, and vaccines was applied. To estimate the association of HPV awareness with selected factors, prevalence ratios (PR were estimated using a generalized linear model (GLM. Results Three hundred and one primiparous women were included; 37% of them reported that they "had ever heard about HPV", but only 19% and 7%, respectively, knew that HPV is a sexually transmitted infection (STI and that it can cause cervical cancer. Seventy-four percent of interviewees mentioned the preventive character of vaccines and all participants affirmed that they would accept HPV vaccination after delivery. In the multivariate analysis, only increasing age (P for trend = 0.021 and previous STI (P Conclusions This survey indicated that knowledge about the association between HPV and cervical cancer among primiparous young women is low. Therefore, these young low-income primiparous women could benefit greatly from educational interventions to encourage primary and secondary cervical cancer prevention programs.

    Little is known about specific learning disorder (SLD) in low- and middle-income countries (LMICs), and even less from representative school samples in small size cities outside huge urban centers. Few studies addressed the new DSM-5 criteria for SLDs. We investigated the prevalence of DSM-5 SLDs, their comorbidities and correlates in school samples of students from the second to sixth grades living in median cities from four different geographic regions in Brazil. A national test for academic performance covering reading, writing and mathematical abilities was applied. Psychiatric diagnoses were assessed by the K-SADS-PL applied to the primary caregiver. A total of 1618 children and adolescents were included in the study. The following prevalence rates of SLDs were found: 7.6% for global impairment, 5.4% for writing, 6.0% for arithmetic, and 7.5% for reading impairment. Attention-deficit/hyperactivity disorder (ADHD) was the only comorbidity significantly associated with SLD with global impairment (p = 0.031). Anxiety disorders and ADHD were associated with SLD with arithmetic impairment. Significant differences were detected in prevalence rates among cities, and several socio-demographic correlates (age, gender, IQ, and socioeconomic status) were significantly associated with SLD with global impairment in our sample. Careful validation and normatization of instruments to assess academic performance is a major problem in LMICs. As expected, we found a significant heterogeneity in prevalence rates of SLD according to geographic regions considering that Brazil is a country with a robust diversity. SLD with global and arithmetic impairment was significantly associated with psychiatric comorbidities. PMID:25925785

    Full Text Available A cross-sectional study on the prevalence of schistosomiasis mansoni in three sites of the "Baixada Ocidental Maranhense" was carried out in 1993 in: Alegre (in the municipality of São Bento, Aliança (in Cururupu and Coroatá II (in the municipality of São João Batista. Results were compared to those of another study performed at the same sites and in similar conditions, in 1987. The entire population of the three sites, with few exceptions, was submitted to fecal tests using the Kato-Katz method and immediate intradermal tests for schistosomiasis in both studies. Subjects with positive results in one of these tests were clinically evaluated by a physical examination. In 1993, the total of 827 subjects were submitted to fecal examination and 826 to intradermal test. Schistosoma mansoni eggs were found in the feces of 154 (18.6% subjects, while 478 (57.9% subjects presented a positive intradermal test. Stool examination was carried out in 367 subjects in Alegre with a positivity rate of 14.9%; the intradermal test, performed in 366 subjects, was positive in 47.5% of the cases. In Aliança, 277 subjects had their feces examined and were submitted to an intradermal test, with a positivity rate of 34.4% and 70.7%, respectively. Finally in Coroatá II, 183 inhabitants submitted to fecal and intradermal tests had positivity rates of 2.2% and 59.0%, respectively. When the present data were compared to those obtained in the survey performed in 1987, a significant decrease in the prevalence of infection by S. mansoni was observed in Alegre and Coroatá II, and a prevalence increase in Aliança.Esquistossomose mansoni na Baixada Ocidental Maranhense, Estado do Maranhão, Brasil: estudos transversais realizados em 1987 e 1993 Realizou-se, em 1993, estudo transversal acerca da ocorrência de esquistossomose mansoni em três localidades da Baixada Ocidental Maranhense: Alegre (município de São Bento, Aliança (município de Cururupu e Coroatá II

  13. Technical study on cross section measurement with Al activation

    International Nuclear Information System (INIS)

    The method of Al activation relative measurement of cross section has been studied. The cross sections of 27Al(n,α)24Na have been measured in 13.4 MeV to 14.7 MeV. The PD-300 accelerator offered D-T neutron source. The distance from sample to Tritium target is 20 cm. It spent 5 h to radiate sample with neutron. The intensity of neutron source is monitored by the α-particles from the T(d, n) 4He reaction. The induced neutron energy is determined using ratio of Nb(n,2n) and Zr(n,2n) cross section. The activated gamma ray is measured using GEM60P HPGe detector. The results of 27Al(n, α)24Na cross sections are compared with the nuclear data standard, and the deviation is less than 1%. It showed that the method of Al activation relative measurement of cross section is credible. (authors)

    Full Text Available Population-based prevalence studies are essential tools for screening of hepatitis A and provide important data on susceptible groups. However, surveillance in isolated communities is difficult because of the limited access to these areas and the need for blood sample collection. This study aimed to determine the anti-HAV prevalence using oral fluid samples to provide an alternative tool for epidemiological studies that might be useful for vaccination-related decisions. The study population was composed of 224 volunteers from South Pantanal, aged 3 to 86 years old. This study was performed using oral fluids, previously standardized for anti-HAV antibody detection, which were collected using a ChemBio device. Eluates were tested using modified commercial EIA to detect anti-HAV antibodies. The overall prevalence was 79.1%, corresponding to 178 reactive EIA tests out of 224 samples. The age stratified data revealed a prevalence of 47.8% between 0–10 years, 84% in 11–20 years and 91.9% in subjects older than 21 years. Results indicate that hepatitis A prevalence was higher in adolescents and adults, corroborating the literature reports. Thus, oral fluid samples could replace serum in HAV epidemiological studies in isolated communities as they are efficient at detecting anti-HAV antibodies.

    Using both cross-sectional and prospective analyses, this study examined vulnerability factors for sexual victimization in 541 female and male Brazilian college students, of whom a subgroup of 250 took part in two measurements 6 months apart. Risk factors for sexual victimization (alcohol consumption, casual sex, and ambiguous communication) in participants' cognitive scripts for consensual sex were linked to sexual victimization via their translation into risky sexual behavior. Pornography use was indirectly linked to sexual victimization through its influence on risky sexual scripts and sexual behavior. Child sexual abuse predicted sexual victimization in the cross-sectional analysis, and victimization since age 14 predicted revictimization in the six months covered by the prospective period. Few gender differences were found. This study is the first prospective investigation of vulnerability factors for sexual victimization in Brazil, and similarities to evidence from North America are discussed. PMID:25795529

    A cross-sectional health study of 101 cryolite workers was performed, using spirometry and a questionnaire. Multiple regression analysis revealed a significant correlation between the index of smoking and a decrease in FEV1 (per cent). There was no significant correlation between work-related exposure and lung function. Many cryolite workers described a group of symptoms appearing after 15 to 30 min of heavy dust exposure: nausea, followed by epigastric pain with relief after spontaneous or provoked vomiting. Thirty-four (33.6 per cent) workers complained of nausea, vomiting or diarrhoea in relation to work, compared to 3.8 per cent of 1752 men participating in the Copenhagen Male Study. PMID:2622142

    2015-01-01

    Full Text Available Elastic and inelastic neutron scattering differential cross sections and γ-ray production cross sections have been measured on 54,56Fe at several incident energies in the fast neutron region between 1.5 and 4.7 MeV. All measurements were completed at the University of Kentucky Accelerator Laboratory (UKAL using a 7-MV Model CN Van de Graaff accelerator, along with the neutron production and neutron and γ-ray detection systems located there. The facilities at UKAL allow the investigation of both elastic and inelastic scattering with nearly mono-energetic incident neutrons. Time-of-flight techniques were used to detect the scattered neutrons for the differential cross section measurements. The measured cross sections are important for fission reactor applications and also for testing global model calculations such as those found at ENDF, since describing both the elastic and inelastic scattering is important for determining the direct and compound components of the scattering mechanism. The γ-ray production cross sections are used to determine cross sections to unresolved levels in the neutron scattering experiments. Results from our measurements and comparisons to model calculations are presented.

Adjusted hierarchical analysis was performed using Poisson regression. Prevalence of child labor was 13.8%. Current smoking prevalence was 6.3% in the sample as a whole (15.7% among working versus 3.4% among non-working children. In the multivariate analysis, smoking was significantly associated with child labor, with a prevalence ratio of 1.75 (95%CI: 1.30-2.36. Smoking was also associated with family characteristics (lower maternal schooling, mother currently without husband/partner, household members with alcohol or drug problems, single mother, and history of serious injuries, and the children's characteristics (age greater than 16 years, inadequate school performance, and externalizing behavior. The findings point to smoking as one of the harmful consequences of child labor and suggest the workplace as an appropriate target for smoking prevention.Este estudo transversal avaliou a associação entre o tabagismo e o trabalho de crianças e adolescentes, através de análise multivariada hierárquica por regressão de Poisson.

    Grit, defined as perseverance of effort and consistency of interest, has attracted attention as a predictor of success in various fields beyond IQ and the Big Five personality dimension of Conscientiousness. The purpose of the current study was to examine previously uninvestigated questions regarding grit using a cross-sectional design among a large number of working adults in Japan. First, we tested geographical generalizability of associations between grit and orientations towards happiness by comparing previous studies in the U.S. and the current study in Japan. It was confirmed that orientation towards meaning rather than orientation towards engagement had a stronger positive correlation with grit in our sample of Japanese people. This result is inconsistent with previous studies in the U.S. Furthermore, the Big Five dimension of Openness to Experience was newly confirmed as having a positive association with grit. Second, we examined the association between grit and work engagement, which is considered as an outcome indicator for work performance. In this analysis, grit was a strong predictor for work performance as well as academic performance. PMID:26335001

    Full Text Available Background Employee engagement is the emotional commitment of the employee towards the organisation. We aimed to analyse baseline work engagement using Utrecht Work Engagement Scale (UWES at a teaching hospital. Methods We have conducted a cross-sectional study within the National Health Service (NHS Teaching Hospital in the UK. All participants were working age population from both genders directly employed by the hospital. UWES has three constituting dimensions of work engagement as vigor, dedication, and absorption. We conducted the study using UWES-9 tool. Outcome measures were mean score for each dimension of work engagement (vigor, dedication, absorption and total score compared with control score from test manual. Results We found that the score for vigor and dedication is significantly lower than comparison group (P< 0.0001 for both. The score for absorption was significantly higher than comparison group (P< 0.0001. However, total score is not significantly different. Conclusion The study shows that work engagement level is below average within the NHS employees. Vigor and dedication are significantly lower, these are characterised by energy, mental resilience, the willingness to invest one’s effort, and persistence as well as a sense of significance, enthusiasm, inspiration, pride, and challenge. The NHS employees are immersed in work. Urgent need to explore strategies to improve work engagement as it is vital for improving productivity, safety and patient experience.

    Full Text Available With recent technology in radar cross section reduction (RCSR, a periodic array of frequency selective surfaces (FSSs which exploits a non-metallic ground plane and slot embedded in the patch elements have been presented. In this study, the single layer FSSs with different incidence angles and substrate thicknesses have been investigated and simulated at the X-band frequency range using CST computer model. Based on the FSSs design, the minimum reflection response is shown to be -74.68 dB while the minimum RCS is -5577 dBm2 occurred at the incidence angle which is equal to 75 degree. Moreover, the maximum value of RCS at -4417 dBm2 has been observed when the incident wave and observer is located at the 0 degree which is offers maximum RCS reduction. Analysis of the CST computer model has been integrated with MATLAB 7 to show the reliability of the two computer model in order to study the feasibility of reflection response in reducing RCS. RCS calculations have been carried out using MATLAB 7 computer model in order to investigate the performance of minimum reflection response which offers reduction in RCS. From the simulated results, it can be concluded that, 75 degree’s incidence angles offered the best performance on RCS reduction due to the angles of incidence, minimum reflection response and lower surface current distribution.

    Full Text Available Estar no mercado de trabalho não deve impedir a mulher de amamentar. A Organização Mundial de Saúde preconiza o aleitamento materno exclusivo até seis meses de vida. No Brasil as leis propiciam à mulher trabalhadora quatro meses de licença maternidade, mas nem sempre ela recebe este benefício. Assim, como praticar amamentação exclusiva? Este artigo objetiva descrever as taxas de aleitamento materno e se o trabalho remunerado interfere na amamentação de mães da Paraíba. Trata-se de estudo transversal em 70 de 223 municípios que aceitaram participar da pesquisa na campanha de vacinação em 2002. Em 11.076 crianças menores de um ano, a prevalência de amamentação exclusiva foi de 22,4% de 0-4 meses e foi significativamente maior entre as mães que trabalhavam fora e que tiveram licença maternidade. Entre estas, foi também menor a prevalência de amamentação total e predominante. Na zona rural o trabalho fora de casa esteve associado com a redução do aleitamento materno exclusivo. A prática do amamentar na Paraíba está muito aquém das recomendações e o retorno precoce da mãe ao trabalho agrava esta situação.Paid work should not be an obstacle to women's breastfeeding. The World Health Organization (WHO recommends exclusive breastfeeding for 6 months. In Brazil, women are legally entitled to 4 months of maternity leave, but in practice few women enjoy such benefits. How is it possible to practice exclusive breastfeeding for 6 months? We analyzed both the breastfeeding rates and whether paid jobs interfere with breastfeeding in Paraíba State, Northeast Brazil. We conducted a cross-sectional study in 70 of 223 municipalities (counties during the annual immunization campaign in 2002. Among 11,076 infants (< 12 months of age, the exclusive breastfeeding rate at 0-4 months was 22.4% and was significantly higher among working women receiving maternity leave as compared to those who did not.

    Full Text Available Background: Tobacco is a leading risk factor for different types of diseases globally. Tobacco smoking by women is culturally unacceptable in India, but still women smoke tobacco at various times of their life. Aims: The aim was to estimate the prevalence and pattern of tobacco use among women and to study the associated sociodemographic factors. Settings And Design: This cross-sectional study was conducted among women aged 30 years or over in an urban resettlement colony for the migrant population at Chandigarh, India. Methodology: The study included women used tobacco products on one or more days within the past 30 days. Through systematic random sampling, 262 women were studied. As a part of the study 144 bidi smoking women were interviewed using detailed semi-structured questionnaire. Statistical Analysis: Descriptive statistics and hypothesis testing with Chi-squared test and logistic regression were done using SPSS 16.0 version. Results: Overall, the prevalence of tobacco use was 29.4% and that of bidi, zarda and hookah were 19.8%, 8.8%, and 2.7%, respectively. Around 6.2% women used tobacco during pregnancy. Teenage was the most common age of initiation of bidi smoking. Logistic regression analysis showed that the prevalence of tobacco use was high among Hindu unemployed women with no formal education belonged to scheduled caste, and those having grandchildren. Conclusions: This study highlighted high rates of tobacco use and explored both individual and family factors related to tobacco use among women. Affordable, culturally acceptable, sustainable and gender-sensitive individual and community-specific interventions will reduce the prevalence and effects of tobacco use.

    Full Text Available To examine the prevalence of hazardous drinking among staff in a UK university and its association with key socio-demographic features.A cross-sectional study.A university in the UK.All employees on the university employee database were eligible to participate. Those who completed and returned the questionnaire were included in the sample. Respondents were 131 university employees.An AUDIT cut-off score of ≥8 was used as a measure of hazardous drinking. AUDIT total score as well as a score of ≥1 in each of the three conceptual domains of alcohol consumption (questions 1-3, dependence symptoms (questions 4-6 and alcohol-related problems (questions 7-10 were used as indicators of levels of drinking and alcohol-related consequences. Secondary outcomes were employees' demographics.Over one third (35% of respondents were classified as hazardous drinkers. Twenty three per cent reported having blackouts after drinking and 14% had injuries or had injured someone. The odds of being a hazardous drinker for an employee in central departments (Human Resources, Registry etc is only one third of that of an employee in science and health-related departments (OR = 0.35, 95% CI = 0.14 to 0.91. The proportion of hazardous drinkers was higher in males compared to females (43% and 30% respectively, part-time compared to full-time (46% and 34% respectively, and academic compared to non-academic employees (39% and 32% respectively, although these were not statistically significant (p>0.05. Furthermore, age, religion and ethnic origin were not found to be significantly associated with hazardous drinking, although total scores were significantly lower for ethnic minorities compared to white employees (p = 0.019.In this study, hazardous drinking was highly prevalent among university employees. However, overt recruiting of staff to address sensitive issues such as alcohol misuse is problematic.

    Background As vitamin D may have a neuroprotective effect, the authors studied the association of biomarkers of vitamin D status and delirium to see if low vitamin D status was common in delirium cases. Methods Biochemical measures of vitamin D (25-hydroxyvitamin D [25-OHD]) and calcium metabolism were used in this retrospective cross-sectional analysis of adult in-patients with delirium, admitted at three Canadian academic hospitals from January 2011 to July 2012. Primary outcome was to determine estimates of the prevalence of hypovitaminosis D in this group in whom vitamin D was checked. Results Seventy-one (5.8%) out of 1,232 delirium inpatients had their vitamin D measured. Thirty-nine (55%) showed vitamin D insufficiency (25-OHD of 25-75 nmol/L) and 8 (11%) showed vitamin D deficiency (25-OHD < 25 nmol/L). Mean serum 25-OHD levels were lower in males (57.1±7.7 nmol/L) than in females (78.2±6.1 nmol/L), p = .01, even when controlled for age and season. Men were younger than the women (74.4±2.3 vs. 82.4±1.7, p = .005). Mean age was 78.7±1.5 years, and 33 (47%) were male. Conclusions Although vitamin D is rarely checked during delirium workup and/or management, high rates of hypovitaminosis D were found to be common in the delirium in-patients in whom it was checked. Larger studies would be needed to estimate the prevalence of hypovitaminosis D in delirium and whether hypovitaminosis D plays a role in the pathogenesis of delirium. PMID:24278095

    The present status of neutrino cross section physics is reviewed focusing on the recent theoretical developments in quasielastic scattering, multi-nucleon contributions to the inclusive scattering and pion production on nucleons and nuclei. A good understanding of these processes is crucial to meet the precision needs of neutrino oscillation experiments. Some of the challenges that arise in the consistent description of MiniBooNE and MINERvA recent data are discussed.

  18. Scaling study of the pion electroproduction cross sections

    International Nuclear Information System (INIS)

    The 1H(e, e'π+)n cross section was measured for arange of four-momentum transfer up to Q2=3.91 GeV2 at values of the invariant mass W above the resonance region. The Q2 dependence of the longitudinal component was found to be consistent with the Q2-scaling prediction for hard exclusive processes. This suggests that the QCD factorization theorem is applicable at rather low values of Q2. The transverse term falls off slower than the naive Q-8 expectation and remains appreciable even at Q2=3.91 GeV2

  19. Study of the total reaction cross section via QMD

    International Nuclear Information System (INIS)

    This paper presents a new empirical formula to calculate the average nucleon-nucleon (N-N) collision number for the total reaction cross sections (σR). Based on the initial average N-N collision number calculated by quantum molecular dynamics (QMD), quantum correction and Coulomb correction are taken into account within it. The average N-N collision number is calculated by this empirical formula. The total reaction cross sections are obtained within the framework of the Glauber theory. σR of 23Al+12C, 24Al+12C, 25Al+12C, 26Al+12C and 27Al+12C are calculated in the range of low energy. We also calculate the σR of 27Al+12C with different incident energies. The calculated σR are compared with the experimental data and the results of Glauber theory including the σR of both spherical nuclear and deformed nuclear. It is seen that the calculated σR are larger than σR of spherical nuclear and smaller than σR of deformed nuclear, whereas the results agree well with the experimental data in low-energy range.

    Full Text Available Introduction: An adequate hydration is critical for a series of body functions, including proper regulation of core body temperature, elimination of waste metabolites by the kidney and maintenance of normal physical and cognitive functions. Some institutions have set recommendations for adequate intake of water, but these recommendations vary widely. Objective: To estimate the usual daily consumption of fluids (water and all other beverages by a selective sample of Mexican population. Methods: Cross-sectional sample of 1,492 male and female adults between 18-65 years of age, drawn from 16 cities throughout Mexico. Self-reported fluid intake data collected over a 7-day consecutive period, recording intake of water, milk and derivatives, hot beverages, sugar sweetened beverages (SSB, alcoholic beverages and others. Results: We found that 87.5% of adult males and 65.4% of adult females reported drinking below their recommended daily fluid intake (3 L for males and 2 L for females, and in 80% of the population SSB, not including hot beverages or milk and derivatives, accounted for a larger amount and proportion of fluid intake than plain water. Sixty-five percent of adult males and 66% of adult females consumed more than 10% of their estimated daily caloric intake from fluids. Fluid intake did not differ significantly by gender, but showed a declining trend with age. Conclusion: Our findings may have important implications for policy recommendations, as part of comprehensive strategies to promote the adoption of healthy life styles, in this case, promoting consumption of plain water while discouraging excessive consumption of caloric beverages.

    Full Text Available Background: Hypokalemia is a very common electrolyte imbalance in diabetic patients which leads to substantial morbidity and mortality. Severe hypokalemia is associated with lifethreatening arrhythmias and sudden cardiac death. There are no adequate studies regarding the incidence and factors precipitating hypokalemia in Bangladeshi diabetic subjects. Objective: The objective of this study was to find out the factors precipitaing hypokalemia in diabetic patients. Materials and Methods: A total 95 admitted diabetic patients with hypokalemia were studied. Specimens were collected from all adult diabetic patients with serum potassium level <3.5 mmol/L irrespective of cause of admission. Informations were obtained in a semistructured data collection form and analyzed. Results: Most of the subjects (61.1% belonged to the age group of 60 years and above, 31.5% to the age group 40–59 years and 7.4% belonged to the age group of 20–39 years. Sixty one (64.2% patients were females and 34 (35.8% were males. In 63.2% cases, vomiting was found as a factor causing hypokalemia in the diabetic patients. Other common factors precipitaing hypokalemia were diarrhea (42.1%, inadequate diet (9.5%, severe hyperglycemia (3,2%, diabetic ketoacidosis (6.3% and drugs especially diuretics (18.9%, bronchodilators (6.3% and steroids (5.3%. The commonest comorbidity associated with diabetes was hypertension. Conclusion: In this study the commonest precipitating factor causing hypokalemia was vomiting. Majority of hypokalemic patients were female and of older age group. When hypokalemia is identified, the underlying precipitating factor should be sought and the disorder treated. Diuretics should be used with caution in the elderly patients having hypertension, a common comorbid condition of diabetes, as these patients are susceptible to develop hypokalemia.

    The use of portion control practices has rarely been quantified. The present study aimed to: (1) explore which portion control practices are actually used by the general population and their association with cognitive restraint, demographic background and general health interest (GHI), and (2) examine how the usage of portion control practices predicts the estimated consumption of an energy dense food (i.e. pizza). Twenty-two portion control practices were rated in terms of their frequency of use from 'never' to 'very often' by a representative sample of 1012 consumers from the island of Ireland. Three factors were extracted and named: measurement-strategy scale, eating-strategy scale, and purchasing-strategy scale. The eating-strategy scale score was the highest, while the measurement-strategy scale carried the lowest frequency score. For each strategy scale score, the strongest predictor was GHI, followed by gender. Having higher GHI and being female were independently associated with more frequent portion control. Both the eating-strategy scale score and the purchasing-strategy scale score were negatively associated with pizza portion size consumption estimates. In conclusion, while this study demonstrates that the reported use of portion control practices is low, the findings provide preliminary evidence for their validity. Further studies are needed to explore how portion control practices are used in different kinds of portion size decisions and what their contribution is to the intake of food over an extended period of time.

    Full Text Available Abstract Background Lengthy questionnaires reduce data quality and impose a burden on respondents. Previous researchers proposed that a single item ("My future seems dark to me" and a 4-item component of the Beck's Hopelessness Scale (BHS can summarise most of the information the BHS provides. There is no clear indication of what BHS cutoff values are useful in identifying people with suicide tendency. Methods In a population-based study of Chinese people aged between 15 and 59 in Hong Kong, the Chinese version of the BHS and the Centre for Epidemiologic Studies – Depression scale were administered by trained interviewers and suicidal ideation and suicidal attempts were self-reported. Receiver operating characteristics curve analysis and regression analysis were used to compare the performance of the BHS and its components in identifying people with suicidality and depression. Smoothed level of suicidal tendency was assessed in relation to scores on the BHS and its component to identify thresholds. Results It is found that the 4-item component and, to a lesser extent, the single item of the BHS perform in ways similar to the BHS. There are non-linear relationship between suicidality and scores on the BHS and the 4-item component; cutoff values identified accordingly have sensitivity and specificity of about 65%. Conclusion The 4-item component is a useful alternative to the BHS. Shortening of psycho-social measurement scales should be considered in order to reduce burden on patients or respondents and to improve response rate.

    As e-commerce and online pharmacies (OPs) arose, the potential impact of the Internet on the world of health shifted from merely the spread of information to a real opportunity to acquire health services directly. Aim of the study was to investigate the offer of prescription drugs in OPs, analysing their characteristics, using the content analysis method. The research performed using the Google search engine led to an analysis of 118 online pharmacies. Only 51 (43.2%) of them stated their precise location. Ninety-six (81.4%) online pharmacies did not require a medical prescription from the customer's physician. Online pharmacies rise complex issues in terms of patient-doctor relationship, consumer empowerment, drug quality, regulation and public health implications. PMID:19151103

    Abstract. Malnutrition is one of the most prevalent problems in older people, but there is little information about the nutritional status of the older women in China. Therefore, this study was conducted to investigate the nutritional status and clinically correlated factors for malnutrition in older Han women in China. In total, 2,556 hospital- and community-based Han women aged 60 years or older were recruited between May 2007 and December 2014. All women completed comprehensive geriatric assessment, and the Mini Nutritional Assessment Short Form (MNA-SF) was used to assess the nutritional status. The clinically corre- lated factors for malnutrition were also analyzed, including social factors, health status, and dietary behavior. The average age of these women was 75.9 ± 9.4 years, and 63.8% women lived in urban areas. Of the total respondents, 344 and 716 women were classified as malnutrition and at risk of malnutrition, respectively. Five factors were independently and positively correlated with poor nutrition, including chronic obstructive pulmonary disease (COPD), gastrointestinal disease, depression, cognitive impairment, and comorbidity (≥ 2). Three factors were independently and negatively correlated with poor nutrition, including economic status, meat intake, and fish intake. The older Han women with these five health problems should be given more attention with regards to their nutritional status. Improving economic status, eating more meat and fish were recommended for preventing poor nutrition in older women. PMID:27086430

    2014-07-01

    Full Text Available BACKGROUND: Menstruation has often been dealt with secrecy in many cultures. Such perceptions coupled with poor and inadequate sanitary facilities have often kept girls from not attending schools especially during periods of menstruation. There is gross lack of information on menstrual management among adolescent girls; most of these girls seek information about menstruation from their peers who do not know better. Adolescence being a time of tremendous opportunity, and at the same time also a time of heightened vulnerabilities, it is imperative to empower adolescent girls with adequate information and skills on crucial issues like menstrual hygiene and its management. AIM: To know the knowledge and menstrual hygiene practices of adolescent girls. MATERIAL & METHODS: Across sectional study was conducted among 210 adolescent girls in a rural field practice area of Rajarajeswari Medical College & Hospital. Data on socio-economic variables and menstrual characteristics were collected using pre-tested questionnaires. RESULTS: 87.6% of the girls were aware about menstruation prior to the attainment of menarche. Mothers were the first informants in about 56.5% girls. Overall 51.5% adolescent girls were using sanitary napkins as menstrual absorbent, while 45.6% were using used cloths. Regarding practices, for cleaning of used cloths 88.9% girls used both soap and water. Regarding restrictions practiced, 97.6% girls practiced different restrictions during menstruation. CONCLUSION: There is a need to educate the girls about menstruation, its importance and hygiene maintenance; so as to enable them to lead a healthy reproductive life in future.

    Abstract Objective To investigate the magnitude and characteristics of medical tourism in Thailand and the impact of such tourism on the Thai health system and economy. Methods In 2010, we checked the records of all visits to five private hospitals that are estimated to cover 63% of all foreign patients. We reviewed hospital records of foreign patients and obtained data on their countries of origin, diagnoses and interventions. We surveyed 293 medical tourists to collect demographic characteristics and information on their expenditure and travelling companions. To help understand the impact of medical tourism on the Thai health system, we also interviewed 15 hospital executives and 28 service providers from the private hospitals. Findings We obtained 911 913 records of hospital visits, of which 324 906 came from 104 830 medical tourists. We estimated that there were 167 000 medical tourists in Thailand in 2010. Of the medical tourists who attended our study hospitals, 67 987 (64.8%) came from the eastern Mediterranean region or Asia and 109 509 (34%) of them were treated for simple and uncomplicated conditions – i.e. general check-ups and medical consultations. The mean self-reported non-medical expenditure was 2750 United States dollars. According to the hospital staff interviewed, medical tourism in 2010 brought benefits to – and apparently had no negative impacts on – the Thai health system and economy. Conclusion We estimate that the total number of medical tourists visiting Thailand is about 10% of previous national government estimates of 1.2 million. Such tourists appear to bring economic benefits to Thailand and to have negligible effects on the health system. PMID:26769994

A sample size of 412 animals was estimated assuming unknown prevalence (set at 50%. Virus neutralization assay was used to the detect the presence of antibodies for BVDV-1 and the results found were analysed using multivariable logistic regression model. The obtained prevalence was 4% at animal level and 45% at the animal and herd level. The titers were highly variable between animals and within farms. The multivariable logistic regression analysis showed an association between being housed outside and exposure to BVDV-1 (OR=0.24, 95% CI:0.06, 0.96, P=0.04. Highly correlated data and low prevalence of antibodies at the animal level resulted in insufficient power to detect significant differences with other selected risk factors. In conclusion, the prevalence is within the range reported for other countries.

  17. Molecular dynamical and structural studies for the bakelite by neutron cross section measurements

    International Nuclear Information System (INIS)

    Neutron reaction cross sections were determined by transmission and scattering measurements, to study the dynamics and molecular structure of calcined bakelites. Total cross sections were determined, with a deviation smaller than 5%, from the literature values, by neutron transmission method and a specially devised approximation. These cross sections were then correlated with data obtained with infra-red spectroscopy, elemental analysis and other techniques to get the probable molecular formulae of bakelite. Double differential scattering cross sections, scattering law values and frequency distributions were determined with 15% error using the neutron inelastic scattering method. The frequency distributions as well as the overall results from all experimental techniques used in this work allowed to suggest a structural model like polycyclic hydrocarbons, for calcined bakelite at 8000 C.

    Full Text Available OBJECTIVES: To assess the prevalence and levels of burnout syndrome among medical students at the Universidade Federal de Sergipe-Brazil and to identify associated factors. METHODS: A cross-sectional study was performed with randomly selected students in 2009. The Maslach Burnout Inventory/Student Survey (MBI-SS and a structured questionnaire on socio-demographic characteristics, the educational process, and individual aspects were used. Statistical evaluation of multiple variables was performed through backward stepwise logistic regression analysis. RESULTS: The prevalence of burnout was 10.3% (n = 369. The prevalence was higher among those who did not have confidence in their clinical skills (Odds Ratio-OR = 6.47, those who felt uncomfortable with course activities (OR = 5.76, and those who did not see the coursework as a source of pleasure (OR = 4.68. CONCLUSION: There was a significant prevalence of burnout among the medical students studied. Three variables, in particular, were associated with burnout and were directly related to the medical education process. Preventive and intervention measures must be adopted, and longitudinal studies should be conducted.

  1. Advanced Neutron Source Cross Section Libraries (ANSL-V): ENDF/B-V based multigroup cross-section libraries for advanced neutron source (ANS) reactor studies

    International Nuclear Information System (INIS)

    Pseudo-problem-independent, multigroup cross-section libraries were generated to support Advanced Neutron Source (ANS) Reactor design studies. The ANS is a proposed reactor which would be fueled with highly enriched uranium and cooled with heavy water. The libraries, designated ANSL-V (Advanced Neutron Source Cross Section Libraries based on ENDF/B-V), are data bases in AMPX master format for subsequent generation of problem-dependent cross-sections for use with codes such as KENO, ANISN, XSDRNPM, VENTURE, DOT, DORT, TORT, and MORSE. Included in ANSL-V are 99-group and 39-group neutron, 39-neutron-group 44-gamma-ray-group secondary gamma-ray production (SGRP), 44-group gamma-ray interaction (GRI), and coupled, 39-neutron group 44-gamma-ray group (CNG) cross-section libraries. The neutron and SGRP libraries were generated primarily from ENDF/B-V data; the GRI library was generated from DLC-99/HUGO data, which is recognized as the ENDF/B-V photon interaction data. Modules from the AMPX and NJOY systems were used to process the multigroup data. Validity of selected data from the fine- and broad-group neutron libraries was satisfactorily tested in performance parameter calculations

    Chagas disease was investigated in two new settlements of landless rural workers inhabiting prefabricated, triatomine-proof houses and in four neighboring older communities where mud huts were still well suitable for vectors. Through a cross-sectional survey and entomological assessment, we surveyed 148 houses/families in the two new settlements and in 47 houses/families in the four older localities. We determined seroprevalence of Chagas disease through IFI and Elisa (eluates) assays and searched for vectors in the domestic and peridomestic environments. Seroprevalence reached 0.6% (3/466) in the new settlements and 0.8% (1/115) in the older communities. Triatomines were not found in the new settlements, while 7 Triatoma brasiliensis, 4 T. pseudomaculata, 1 Panstrongylus lutzi, and 145 Rhodnius nasutus were collected in the older localities. In addition, a colony of T. brasiliensis (n = 55) was encountered inside a school attended by children of the region. Parasite strains isolated from the insects were characterized as T. cruzi I. Despite the low prevalence of Chagas disease in both scenarios, entomological surveillance must be strengthened and housing improvement reinforced in order to control vector transmission. The risk of infection by the vectors was lower in the settlements of improved homes, where conditions for colonization of the peridomestic environment by transmitting insects were not observed.

    Improvements of the Monte Carlo transport codes and cross-section libraries are very important steps towards usage of the accelerator-driven transmutation systems. We have conducted a lot of benchmark experiments with different set-ups consisting of lead, natural uranium and moderator irradiated by relativistic protons and deuterons within framework of the collaboration “Energy and Transmutation of Radioactive Waste”. Unfortunately, the knowledge of the total or partial cross-sections of important reactions is insufficient. Due to this reason we have started extensive studies of different reaction cross-sections. We measure cross-sections of important neutron reactions by means of the quasi-monoenergetic neutron sources based on the cyclotrons at Nuclear Physics Institute in Řež and at The Svedberg Laboratory in Uppsala. Measurements of partial cross-sections of relativistic deuteron reactions were the second direction of our studies. The new results obtained during last years will be shown. Possible use of these data for improvement of libraries, models and benchmark studies will be discussed.

  4. Studies of neutron cross-sections important for spallation experiments using the activation method

    International Nuclear Information System (INIS)

    A series of experiments devoted to studies of neutron cross-sections by activation method was carried out. The cross-sections of various threshold reactions were studied by means of different quasi-monoenergetic neutron sources with energies from 14 MeV up to 100 MeV. Threshold reactions in various materials are among other used to measure fast neutron fields produced during accelerator driven system studies. For this reason our measurements of neutron cross-sections are crucial. At present, neither experimental nor evaluated data above 30 MeV are available for neutron threshold reactions in Au, I and In published in this proceedings. We studied materials in the form of thin foils and compared our data with the calculations preformed using the deterministic code TALYS 1.4.

  5. Cross-section studies of important neutron and relativistic deuteron reactions

    International Nuclear Information System (INIS)

    The cross-sections of relativistic deuteron reactions on natural copper were studied by the means of activation method. The deuteron beams produced by JINR Nuclotron (Russia) with energies from 1 GeV up to 8 GeV were used. Lack of such cross-sections prevents the usage of copper foils for beam integral monitoring. The copper monitors will help us to improve the beam integral determination during ADS studies. The yttrium samples are very suitable activation detectors for monitoring of neutron fields not only in the ADS studies. But experimental cross-section data for higher energy threshold neutron reactions are still missing. This situation is the reason why we have started to study neutron reactions on yttrium by the means of quasi mono-energetic neutron source based on NPI Řež cyclotron (Czech Republic).

  6. (x, xn γ) reaction cross section measurements for (n,xn) reaction studies

    International Nuclear Information System (INIS)

    In the context of improvement of nuclear data bases for future nuclear reactor researches, we study (n,xn) reactions experimentally with the help of the (n,xn γ) technique. The experiments are performed at the GELINA facility which delivers a pulsed, white neutron beam. Several measurement campaigns have been performed on 235U, 232Th, 182,183,184,186W and 238U isotopes. The (n,xn γ) technique consists in detecting the γ radiations from the decay of the excited nucleus created by the (n,xn) reaction using Planar High-Purity germanium (HPGe) detectors. Thus we can determine the γ production cross section. Up to now we can reach cross section uncertainties from 5 to 7% for neutron energies up to 9 MeV and 20% in the high neutron energy range. A compilation of all these experimental cross sections (mostly still preliminary) compared to theoretical predictions are discussed

    Full Text Available Abstract Background Japan provides universal health insurance to all legal residents. Prior research has suggested that immigrants to Japan disproportionately lack health insurance coverage, but no prior study has used rigorous methodology to examine this issue among Latin American immigrants in Japan. The aim of our study, therefore, was to assess the pattern of health insurance coverage and predictors of uninsurance among documented Latin American immigrants in Japan. Methods We used a cross sectional, mixed method approach using a probability proportional to estimated size sampling procedure. Of 1052 eligible Latin American residents mapped through extensive fieldwork in selected clusters, 400 immigrant residents living in Nagahama City, Japan were randomly selected for our study. Data were collected through face-to-face interviews using a structured questionnaire developed from qualitative interviews. Results Our response rate was 70.5% (n = 282. Respondents were mainly from Brazil (69.9%, under 40 years of age (64.5% and had lived in Japan for 9.45 years (SE 0.44; median, 8.00. We found a high prevalence of uninsurance (19.8% among our sample compared with the estimated national average of 1.3% in the general population. Among the insured full time workers (n = 209, 55.5% were not covered by the Employee's Health Insurance. Many immigrants cited financial trade-offs as the main reasons for uninsurance. Lacking of knowledge that health insurance is mandatory in Japan, not having a chronic disease, and having one or no children were strong predictors of uninsurance. Conclusions Lack of health insurance for immigrants in Japan is a serious concern for this population as well as for the Japanese health care system. Appropriate measures should be taken to facilitate access to health insurance for this vulnerable population.

  3. Study of the elastic scattering differential cross sections of a proton beam by a cesium target

    International Nuclear Information System (INIS)

    The elastic differential cross section of H+ on Cs is studied experimentally and theoretically. The experimental device is described, after which the differential cross-section values obtained as a function of the laboratory angle are given for four incident energies: 13.4 eV, 15.1 eV, 17.7 eV and 24.2 eV. By means of an interaction potential of the quasi-molecule H+Cs the differential cross sections are calculated for the same incident energies; this calculation uses the semi-classical method of stationary phases which shows clearly the limits of conventional description and the changes introduced by quantum effects. Very good agreement is obtained between theoretical and experimental results, which shows that elastic scattering is very little perturbed by inelastic channels in this energy range. The estimated inelastic cross section at 24 eV is about 1.9 10-15cm2, corresponding to 1.6% of the scattering process

  9. Cross-section studies of relativistic deuteron reactions on copper by activation method

    International Nuclear Information System (INIS)

    The cross-sections of relativistic deuteron reactions on natural copper were studied in detail by means of activation method. The copper foils were irradiated during experiments with the model spallation targets in the Joint Institute for Nuclear Research. The irradiation of activation samples was performed by beams in the energy range from 1 to 8 GeV. Residual nuclides were measured by the gamma spectrometry. While the EXFOR database contains sets of data for relativistic proton reactions, data for deuteron reactions in this energy range are almost missing. Lack of such experimental cross-section values prevents the use of copper foils from beam integral monitoring. For this reason our experiments focused on their measurement and completely new data were obtained in the energy region where no experimental data have been available so far. The copper monitors with their low sensitivity to fast neutrons will contribute to improvement of the beam integral determination during accelerator-driven system studies

  12. Studies of jet cross-sections and production properties with the ATLAS and CMS detectors

    CERN Document Server

    Anjos, Nuno; The ATLAS collaboration

    2015-01-01

    Several aspects of jet production in pp collisions have been measured by the ATLAS and CMS collaborations. The jet production cross sections probe the dynamics of QCD and can constrain the parton proton structure. Double-differential cross sections for inclusive, di-, three- and four-jet final states are measured at different centre-of-mass energies of pp collisions with the ATLAS detector and are compared to expectations based on NLO QCD calculations. The distribution of the jet charge has been measured in dijet events using pp collision data at 8 TeV with the ATLAS detector. Jet-jet energy correlations are sensitive to the strong coupling constant. Measurements of multi-jet systems with a veto on additional jets, probe QCD radiation effects. These measurements constitute precision tests of QCD in a new energy regime. Studies of large-radius jet properties including N-subjettines, splitting scales and other jet substructure related quantities will be presented.

  13. Theoretical study on fusion dynamics and evaporation residue cross sections for superheavy elements

    International Nuclear Information System (INIS)

    The nuclear dynamical deformation, the fusion probability and the evaporation residue (ER) cross sections for the synthesis of superheavy nuclei are studied with the di-nuclear system model and the related dynamical potential energy surface. The intrinsic energy and the maximum dynamical deformations for 48Ca+248Cm are calculated. The effect of dynamical deformation on the potential energy surface and fusion is investigated. It is found that the dynamical deformation influences the potential energy surface and fusion probability significantly. The dependence of the fusion probability on the angular momentum is investigated. The ER cross sections for some superheavy nuclei in 48Ca induced reactions are calculated and it is found that the theoretical results are in good agreement with the experimental results. (authors)

The secondly using 15 to 200 GeV neutrinos reacting in BEBC filled with neon and implemented with a liquid hydrogen target, yields, by a comparison of both medium, to a cross section ratio of 1.98+-0.19 and to an indication of it increase as a function of the Bjorken x

  15. Study of 11B + 12C and 10B + 13C fusion cross sections

    International Nuclear Information System (INIS)

    In an effort to understand the mechanism responsible for fusion cross section limitations in light heavy-ion systems, four entrance channels which form the 23Na compound nucleus have been studied. A limitation mechanism based on a critical density of compound nucleus states does not appear to be responsible for the fusion cross section limitation at energies from approximately one to three times the Coulomb barrier energy. The possibility exists, however, that such a process becomes important at higher energies. To address this question, measurements which utilize the Argonne tandem-linac accelerator have now been completed in the energy range 42.5-80.9 MeV for the 11B + 12C and the 10B + 13C. The preliminary findings of this work are reported here

  16. Infrared cross-sections and integrated band intensities of propylene: Temperature-dependent studies

    KAUST Repository

    Es-sebbar, Et-touhami

    2014-01-01

    Propylene, a by-product of biomass burning, thermal cracking of hydrocarbons and incomplete combustion of fossil fuels, is a ubiquitous molecule found in the environment and atmosphere. Accurate infrared (IR) cross-sections and integrated band intensities of propylene are essential for quantitative measurements and atmospheric modeling. We measured absolute IR cross-sections of propylene using Fourier Transform Infrared (FTIR) Spectroscopy over the wavenumber range of 400-6500cm-1 and at gas temperatures between 296 and 460K. We recorded these spectra at spectral resolutions ranging from 0.08 to 0.5cm-1 and measured the integrated band intensities for a number of vibrational bands in certain spectral regions. We then compared the integrated band intensities measured at room temperature with values derived from the National Institute of Standards and Technology (NIST) and the Pacific Northwest National Laboratory (PNNL) databases. Our results agreed well with the results reported in the two databases with a maximum deviation of about 4%. The peak cross-sections for the primary bands decreased by about 20-54% when the temperature increased from 296 to 460K. Moreover, we determined the integrated band intensities as a function of temperature for certain features in various spectral regions; we found no significant temperature dependence over the range of temperatures considered here. We also studied the effect of temperature on absorption cross-section using a Difference Frequency Generation (DFG) laser system. We compared the DFG results with those obtained from the FTIR study at certain wavenumbers over the 2850-2975cm-1 range and found a reasonable agreement with less than 10% discrepancy. © 2013 Elsevier Ltd.

    Hai-Jun, Zhao; Wei-Long, Liu; Meng-Li, Du

    2016-03-01

    The photodetachment cross section of H- in a linear harmonic oscillator potential is investigated. This system provides a rare example that can be studied analytically by both quantum and semiclassical methods with some approximations. The formulas of the cross section for different laser polarization directions are explicitly derived by both the traditional quantum approach and closed-orbit theory. In the traditional quantum approach, we calculate the cross sections in coordinate representation and momentum representation, and get the same formulas. We compare the quantum formulas with closed-orbit theory formulas, and find that when the detachment electron energy is larger than , where ω is the frequency of the oscillator potential, the quantum results are shown to be in good agreement with the semiclassical results.

    Both satisfaction and mindfulness relate to sustained physical activity. This study explored their relationship. We conducted a cross-sectional study with 398 Dutch participants who completed measures on trait mindfulness, mindfulness and satisfaction with physical activity, physical activity habits, and physical activity. We performed mediation and moderated mediation. Satisfaction mediated the effect of mindfulness on physical activity. Mindfulness was related to physical activity only when one's habit was weak. The relation of mindfulness with satisfaction was stronger for weak compared to strong habit. Understanding the relationship between mindfulness and satisfaction can contribute to the development of interventions to sustain physical activity. PMID:25631662

    Full Text Available Objectives: Published data about the association between the consumption of sweetened soft-drinks (SSD and obesity in childhood are controversial and still inconsistent. In addition, data are lacking in the Spanish population. The purpose of this study was therefore, to explore the cross-sectional association between body composition-related parameters and SSD consumption in Spanish adolescents. Subjects and methods: A representative sample of 1,523 adolescents (768 boys and 755 girls, with complete dietary data as well as anthropometric measurements, were included in this study. Weight, height, waist circumferences, and 6 skinfolds were measured, and BMI and percentage body fat were calculated. From a 24h dietary recall the subjects were grouped in 3 groups according to their SSD consumption: 1 Non-consumers (0 g of SSD consumption; 2 Moderate consumption ( 336 g/day of SSD. Results: 67% males and 75% females did not consume any SSD the day before the dietary recall interview. Males consumed more SSD than females. Regarding the association between SSD consumption and measures of obesity, no difference was observed between the three groups of SSD consumption in any of the anthropometric measurement, BMI or body fat. Conclusion: As no association was present between SSD consumption and obesity in our cross-sectional study we suggest that dietary patterns and habits as well as lifestyle factors such as physical activity should be present when examining cross-sectional or longitudinal relationships with obesity. Multidisciplinary intervention studies are crucial when trying to develop solutions against the increasing obesity epidemic.

    Full Text Available Abstract Background By 1990, 94 percent of the acquired immunodeficiency syndrome (AIDS cases in Romania were in children less than 13 years of age. The majority of the cases were identified in the city of Constanta. The purpose of this paper was to describe the current burden of pediatric human immunodeficiency virus (HIV infection in the Constanta county. Methods A cross-sectional study was designed to address the primary objective. Between April 1999 and March 2000, all living cases of pediatric HIV infection in the Constanta county were identified from records at the HIV hospital clinic which serves the Constanta county. Standard demographic, social, clinical, treatment and hospitalization data were collected for each study subject. Data were analyzed according to cross-sectional study design methodology. Results Of the 762 subjects, the majority were seven to 11 years of age, lived with their parents and attended school. Only 70% of the fathers and 13% of the mothers were employed. Horizontal transmission accounted for 90% of the cases. Most of the children had moderate to severe disease as indicated by their AIDS-defining signs; 40% had AIDS. Less than half of the children were receiving antiretroviral therapy (ART. ART and children of mothers with a high school or greater education were independent predictors of long-term non-progression of HIV disease. Conclusions This cross-sectional study demonstrated that ten years after the HIV epidemic was identified in Romania, it remains a health and economic burden. The infected children are very ill, but ART is not available for all. The proportion with vertical transmission has increased from an estimated four % to nine %. Our findings support the need to get HIV therapy to economically challenged countries such as Romania.

    Introduction: The inadequate reporting of cross-sectional studies, as in the case of the prevalence of metabolic syndrome, could cause problems in the synthesis of new evidence and lead to errors in the formulation of public policies. Objective: To evaluate the reporting quality of the articles regarding metabolic syndrome prevalence in Peruvian adults using the STROBE recommendations. Methods: We conducted a thorough literature search with the terms "Metabolic Syndrome", "Sindrome Metabolico" and "Peru" in MEDLINE/PubMed, LILACS, SciELO, LIPECS and BVS-Peru until December 2014. We selected those who were population-based observational studies with randomized sampling that reported prevalence of metabolic syndrome in adults aged 18 or more of both sexes. Information was analysed through the STROBE score per item and recommendation. Results: Seventeen articles were included in this study. All articles met the recommendations related to the report of the study's rationale, design, and provision of summary measures. The recommendations with the lowest scores were those related to the sensitivity analysis (8%, n= 1/17), participant flowchart (18%, n= 3/17), missing data analysis (24%, n= 4/17), and number of participants in each study phase (24%, n= 4/17). Conclusion: Cross-sectional studies regarding the prevalence of metabolic syndrome in peruvian adults have an inadequate reporting on the methods and results sections. We identified a clear need to improve the quality of such studies. PMID:26848197

    ABSTRACT Introduction: This cross-sectional retrospective study was designed to assess the relationships among breastfeeding duration, nonnutritive sucking habits, convex facial profile, nonspaced dentition, and distoclusion in the deciduous dentition. Materials and methods: A sample of 415 children (228 males, 187 females) aged 4 to 6 years from a mixed Indian population was clinically examined by two orthodontists. Information about breastfeeding duration and nonnutritive sucking habits was obtained by written questionnaire which was answered by the parents. Results: Chi-square test did not indicate any significant association among breastfeeding duration, convex facial profile, and distoclusion. Statistically significant association was observed between breastfeeding duration and nonspaced dentition and also between breastfeeding duration and nonnutritive sucking habits. Nonnutritive sucking habits had a statistically significant association with distoclusion and convex facial profile (odds ratio 7.04 and 4.03 respectively). Nonnutritive sucking habits did not have a statistically significant association with nonspaced dentition. Conclusion: The children breastfed 6 months duration. It can also be hypothesized that nonnutritive sucking habits may act as a dominant variable in the relationship between breastfeeding duration and occurrence of convex facial profile and distoclusion in deciduous dentition.

  4. The Ultimate Monte Carlo: Studying Cross-Sections With Cosmic Rays

    2007-01-01

    The high-energy physics community has been discussing for years the need to bring together the three principal disciplines that study hadron cross-section physics - ground-based accelerators, cosmic-ray experiments in space, and air shower research. Only recently have NASA investigators begun discussing the use of space-borne cosmic-ray payloads to bridge the gap between accelerator physics and air shower work using cosmic-ray measurements. The common tool used in these three realms of high-energy hadron physics is the Monte Carlo (MC). Yet the obvious has not been considered - using a single MC for simulating the entire relativistic energy range (GeV to EeV). The task is daunting due to large uncertainties in accelerator, space, and atmospheric cascade measurements. These include inclusive versus exclusive cross-section measurements, primary composition, interaction dynamics, and possible new physics beyond the standard model. However, the discussion of a common tool or ultimate MC might be the very thing that could begin to unify these independent groups into a common purpose. The Offline ALICE concept of a Virtual MC at CERN s Large Hadron Collider (LHC) will be discussed as a rudimentary beginning of this idea, and as a possible forum for carrying it forward in the future as LHC data emerges.

    2008-01-01

    Background: Street sweepers play an important role in maintaining the health and hygiene within the cities. This job exposes the street sweepers to a variety of risk factors such as dust, toxins and diesel exhaust pollution, which make them vulnerable to develop certain occupational diseases. Therefore, it was thought necessary to study the morbidity profile in this occupational group. Objectives: To study the prevalence of morbidities among street sweepers and comparison group. Study Design: A cross-sectional study with a comparison group. Study Setting: Nagpur Municipal Corporation, Nagpur. Subjects: The study included two groups: (1) A study group comprising 273 street sweepers. (2) A comparison group comprising 142 class IV workers working in the office buildings of Nagpur Municipal Corporation, Nagpur. Materials and Methods: A pretested proforma was used to record the necessary information such as clinical history, sociodemographic factors, findings of clinical examination and investigations performed. Results and Conclusions: The important morbidities detected among street sweepers were the following: anemia (20.5%), hypertension (9.5%), upper respiratory tract infections (URTI) (7.3%) and chronic bronchitis (5.9%). In the comparison group, important morbidities detected were the following: anemia (20.4%), hypertension (11.3%), hyperacidity (9.9%), URTI (7.0%) and refractive error (7.0%). Chronic bronchitis was detected in two subjects (1.4%) of the comparison group. The prevalence of chronic bronchitis was significantly high among street sweepers than that of subjects of the comparison group. Therefore, it is recommended that further studies with a larger sample size be undertaken to identify the factors responsible for higher prevalence of chronic bronchitis among the street sweepers.

  8. The Status of Cross Section Measurements for Neutron-induced Reactions Needed for Cosmic Ray Studies

    Sisterson, J. M.

    2003-01-01

    Cosmic ray interactions with lunar rocks and meteorites produce small amounts of radionuclides and stable isotopes. Advances in Accelerator Mass Spectrometry (AMS) allow production rates to be measured routinely in well-documented lunar rocks and meteorites. These measurements are analyzed using theoretical models to learn about the object itself and the history of the cosmic rays that fell on it. Good cross section measurements are essential input to the theoretical calculations. Most primary cosmic ray particles are protons so reliable cross sections for proton-induced reactions are essential. A cross section is deemed accurate if measurements made by different experimenters using different techniques result in consistent values. Most cross sections for proton induced reactions are now well measured. However, good cross section measurements for neutron-induced reactions are still needed. These cross sections are required to fully account for all galactic cosmic ray interactions at depth in an extraterrestrial object. When primary galactic cosmic ray (GCR) particles interact with an object many secondary neutrons are produced, which also initiate spallation reactions. Thus, the total GCR contribution to the overall cosmogenic nuclide archive has to include the contribution from the secondary neutron interactions. Few relevant cross section measurements have been reported for neutron-induced reactions at neutron energies greater than approximately 20 MeV. The status of the cross section measurements using quasi-monoenergetic neutron energies at iThemba LABS, South Africa and white neutron beams at Los Alamos Neutron Science Center (LANSCE), Los Alamos are reported here.

    Full Text Available Background: In our society, adherence to feminine traits by the female gender had been culturally promoted and socially desired. A few studies, however, entertained the possibility that healthy men and women have some common attributes in their gender orientation. Androgyny and masculinity were found related to positive mental health. Materials and Methods: A cross-sectional study was conducted to assess the level of masculinity and femininity and its relationship with the perception of stress and various psychopathology including anxiety and depression. Results: Masculinity scores of the participants negatively correlated while femininity scores positively correlated with the scores on General Health Questionnaire, Beck′s Depressive Inventory, Beck′s Anxiety Inventory, and Perceived Stress Scale. Conclusion: Androgyny is psychoprotective. Empowerment-oriented psychological approaches aimed to encourage psychological androgyny, and masculinity might be therapeutic.

    Full Text Available Introduction. Lifestyle is the set of behaviors that an individual practices consciously and voluntarily in the course of his or her life. The assessment of nutritional status by anthropometry can lead to the adoption of preventive measures for health. This is especially important in young people, as many authors have noted that the university population is particularly vulnerable for risky customs and habits. Aim. The purpose of this study is to assess and relate lifestyle with nutritional status of university students. Design. Observational descriptive, cross-sectional. Nutritional status was evaluated and the FANTASTIC questionnaire was applied. Results. 88.1% of students have a healthy lifestyle and 65% were classified as normal according to body mass index. Conclusion. The study found that there is a relationship between lifestyle and nutritional status. On the other hand risk behaviors were identified in the dimensions of nutrition, tobacco smoking, sleep and stress.

    Full Text Available Abstract Background In order to ensure that legalized abortion in South Africa improves reproductive health, women must know that abortion is a legal option in the case of unwanted pregnancy. This study investigated knowledge of abortion legislation eight years after the introduction of legal abortion services in one province of South Africa. Methods In 2004/2005, we conducted a cross-sectional study among 831 sexually-active women attending 26 public health clinics in one urban and one rural health region of the Western Cape Province. Results Thirty-two percent of women did not know that abortion is currently legal. Among those who knew of legal abortion, few had knowledge of the time restrictions involved. Conclusion In South Africa there is an unmet need among women for information on abortion. Strategies should be developed to address this gap so that women are fully informed of their rights to a safe and legal termination of pregnancy.

    OBJECTIVE Compare GHb among people with diabetes who have and have not received periodontal care. RESEARCH DESIGN AND METHODS This cross-sectional study linked 5 years of electronic medical record and dental insurance data for dually insured patients with diabetes, ages 40–70 years (n = 5,103). We assessed the association between annual mean GHb (%) and periodontal care (a proxy for periodontitis) defined using claim codes. Among patients who received periodontal care, we assessed the association between GHb and periodontal treatment intensity. We determined associations using linear regression adjusted for potential confounders and tested for effect modification by age, sex, insulin use, diabetes severity, BMI, and smoking. RESULTS Mean GHb was 7.66%; 38% of participants received periodontal care during the 5 years. After multivariate adjustment, patients who received periodontal care had a GHb level 0.08 percentage points higher than patients who did not (P = 0.02). In stratified analyses, the association was present for women (0.18 percentage points higher GHb with periodontal care, P < 0.001) but not significant for men (0.008 percentage points lower, P = 0.86). In patients who received periodontal care, those with one, and with two or more, surgical treatments had GHb 0.25 (P = 0.04) and 0.36 (P = 0.002) percentage points lower, respectively, than patients without periodontal surgeries. CONCLUSIONS This population-based cross-sectional study showed small associations between periodontal care (a proxy for periodontitis) and higher GHb. Well-controlled longitudinal studies or clinical trials are needed to evaluate causality and temporal trends. Sub-analyses suggest that further investigation of this association among women, and by intensity of periodontal treatment, may be of interest. PMID:20504894

    Full Text Available A cross-sectional study in Itagua, Paraguay tested 192 people for the presence, intensity and species of hookworm infection. Fifty-nine percent of these individuals were found to be infected. Intensity of infection was determined on 92% of infected individuals by quantitative egg counts. The high intensity hookworm infections, which cause the greatest morbidity, were clustered between the ages of five and 14 years. No differences were seen between genders. The species of hookworm was determined for parasites reared from 72% of infected individuals. Both Necator americanus and Ancylostoma duodenale were identified, although the former species predominated. We conclude that hookworm infection continues to be a public health problem in Paraguay, particularly among children and adolescents who suffer from high intensity infections. A. duodenale continues to persist in the Western Hemisphere and has not been completely displaced by N. americanus.

    We report studies of photoelectron angular distribution and cross-section for photoionization of xenon 5s electrons using the relativistic multiconfiguration Tamm-Dancoff (MCTD) approximation. We find that MCTD provides a significantly improved agreement with experiment, compared to some of the other relativistic many body approximations such as the relativistic random phase approximation and the relativistic random phase approximation with relaxation, over the entire photon energy region bracketing the near-threshold 5s Cooper minimum, from the 5s threshold up to about 70 eV. The MCTD results in the length form are in much better agreement with the experiment than those in the velocity form, suggesting residual correlations that must be of importance.

    Full Text Available This cross-sectional study aimed to estimate the prevalence of hyperuricemia and associated risk factors among Japanese-Brazilians. We obtained data on demographic, health history, food intake, and laboratory variables. Chi-square and prevalence ratios were used as measures of association. 35.3% of the subjects presented hyperuricemia, which was more frequent in smokers, males, age > 55 years, with co-morbidities, individuals on uric acid-increasing medication, serum creatinine > 1.4mg/dL, high alcohol consumption, and low consumption of milk and dairy products. In the multivariate analysis, the associations remained significant with gender, overweight, central obesity, hypertriglyceridemia, and use of specific drugs. Among males, low intake of saturated fat was associated with hyperuricemia. Individuals with hypertension showed a negative association with dairy product consumption. The high hyperuricemia prevalence suggests that changes in nutritional profile and control of associated co-morbidities could help minimize occurrence of this condition.

Cross-sectional data-collection on daily (15 November 2013 activities of a sample of European HEMSs. A web-based questionnaire with both open and closed questions was used, developed by experts of the European Prehospital Research Alliance (EUPHOREA. Results. We invited 143 bases from 11 countries; 85 (60% reported base characteristics only and 73 (51% sample-day data too. The variety of base characteristics was enormous; that is, the target population ranged from 94.000 to 4.500.000. Of 158 requested primary missions, 62 (0.82 per base resulted in landing. Cardiac aetiology (36% and trauma (36% prevailed, mostly of life-threatening severity (43%, 0.64 per mission. Had HEMS been not dispatched, patients would have been attended by another physician in 67% of cases, by paramedics in 24%, and by nurses in 9%. On-board physicians estimated to have caused a major decrease of death risk in 47% of missions, possible decrease in 22%, minor benefit in 17%, no benefit in 11%, and damage in 3%. Earlier treatment and faster transport to hospital were the main reasons for benefit. The most frequent therapeutic procedure was drug administration (78% of missions; endotracheal intubation occurred in 25% of missions and was an option hardly offered by ground crews. Conclusions. The study proved feasible, establishing an embryonic network of European HEMS. The participation rate was low and limits the generalizability of the results. Fortunately, because of its cross-sectional characteristics and the handy availability of the web platform, the study is easily repeatable with an enhanced network.

The type of ridge was %45.2 normal, %19.2 class I, %8.2 class II and %27.4 class III, respectively. %72.6 of pontics tested have inappropriate design in tissue surface. "nConclusion: It seems that in a high percentage of cases the tissue surface contour of prescribed pontics in department of prosthodontics was incorrect and more attention must be paid to the education of students and technicians.

  11. A Preliminary Study on Time Projection Chamber Simulation for Fission Cross Section Measurements with Geant4

    International Nuclear Information System (INIS)

    We present the details of the TPC simulation with Geant4 and show the results. TPC can provide more information than a fission chamber in that it is possible to distinguish different particle types. Simulations are conducted for uranium and plutonium targets with 20MeV neutrons. The simulation results are compared with the reference and show reasonable results. This is the first phase of study for realizing a TPC in the NFS at RAON, and we have more work to do, such as applying an electric field, signal processing in the simulation, and manufacturing of a TPC. The standard in fission cross section measurement is a fission chamber. It is basically just two parallel plates separated by a few centimeters of gas. A power supply connected to the plates sets up a moderate electric field. The target is deposited onto one of the plates. When fission occurs, the fragments ionize the gas, and the electric field causes the produced electrons to drift to the opposite plate, which records the total energy deposited in the chamber. A Time Projection Chamber (TPC) is a gas ionization detector similar to a fission chamber. However, it can measure the charged particle trajectories in the active volume in three dimensions by adding several readouts on the pad plane (fission chamber has only one readout one a pad plane). The specific ionization for each particle track enables the TPC to distinguish different particle types. A TPC will be used for fission cross section measurements in the Neutron Science Facility (NSF) at RAON. As a preliminary study, we present details of TPC simulation with Geant4 and discuss the results

Foram entrevistados 406 adolescentes de 15 a 19 anos de idade inscritos em uma unidade de saúde da família da zona leste do Município de São Paulo, Brasil, entre maio e dezembro de 2002. Quase a metade dos adolescentes já havia iniciado sua vida sexual, em média aos 15 anos de idade, fossem homens ou mulheres. O início da vida sexual ocorreu, em grande parte, de forma não planejada (72,7% e dentro de casa (86,1%. O uso de um método contraceptivo na primeira relação sexual foi similar entre homens e mulheres (61,0%, entretanto, foi observado um aumento maior na proporção de uso de algum anticonceptivo entre os homens na última relação sexual. Pelo fato de terem iniciado sua vida sexual em relacionamentos estáveis com vínculos afetivo-amorosos, as mulheres mostraram-se mais vulneráveis às DST/AIDS, pois substituíram o preservativo masculino por outros métodos na última relação sexual, enquanto os homens permaneceram utilizando largamente o condom, provavelmente por estarem inseridos em relacionamentos não estáveis.This cross-sectional study aimed to assess gender differences in adolescents in relation to onset of sexual activity. A total of 406 15-19-year-old adolescents from a family health unit in the city of São Paulo, Brazil, were interviewed from May to December 2002.

    Two practically useful quantities have been introduced to characterize a continuous-energy-spectrum neutron beam and to describe transmission phenomena of the beam in the field of quantitative neutron radiography. These quantities are the effective energy instead of a peak energy or a mean energy of the spectrum and an effective total macroscopic (ETM) cross section instead of a total macroscopic (TM) cross section as defined for a monochromatic energy. Four neutron beams have been used to measure ETM cross sections at effective energies of 29.8, 17.2, 9.8 meV, and at the In resonance energy of 1.46 eV. Results are studied as a function of estimated effective energy, where the effective energy was estimated by a beam quality indicator (BQI) which has been proposed recently. Validity of ETM cross sections as a function of the effective energy is discussed and correlated with recent nuclear data.

    This study aimed to determine the profile of the elderly population (>or= 60 years) in two poor municipalities in North and Northeast Brazil in 2005. Using a cross-sectional survey with a systematic sample, previously trained interviewers applied a standard household questionnaire on demographic characteristics, socioeconomic status, household conditions, physical activity, immunization status, health problems, and expenditures on medicines. Of the total sample (n = 1,013), 528 lived in Caracol, Piauí State, and 478 in Garrafão do Norte, Pará State. 56% were 60-69 years old, 10% lived alone, 69% were illiterate, 8% had a family income less than the minimum wage, 24% of the households had a flush toilet, 60% had a radio, television, and refrigerator, 88% reported at least one chronic disease, 47% had to purchase all their medicines out-of-pocket, 84% had received influenza vaccination, and 90% were able to perform normal activities of daily living. Elderly people included in this study showed poor household conditions, inadequate access to health care, and high levels of morbidity. PMID:18709224

    Erythema nodosum leprosum (ENL) is a severe multisystem immune mediated complication of borderline lepromatous leprosy and lepromatous leprosy. ENL is associated with skin lesions, neuritis, arthritis, dactylitis, eye inflammation, osteitis, orchitis, lymphadenitis and nephritis. The treatment of ENL requires immunosuppression, which is often required for prolonged periods of time and may lead to serious adverse effects. ENL and its treatment is associated with increased mortality and economic hardship. Improved, evidence-based treatments for ENL are needed; however, defining the severity of ENL and outcome measures for treatment studies is difficult because of the multiple organ systems involved. A cross-sectional study was performed, by the members of the Erythema Nodosum Leprosum International STudy (ENLIST) Group, of patients with ENL attending seven leprosy referral centres in Brazil, Ethiopia, India, Nepal, the Philippines and the United Kingdom. We systematically documented the clinical features and type of ENL, its severity and the drugs used to treat it. Patients with chronic ENL were more likely to be assessed as having severe ENL. Pain, the most frequent symptom, assessed using a semi-quantitative scale was significantly worse in individuals with "severe" ENL. Our findings will determine the items to be included in a severity scale of ENL which we are developing and validating. The study also provides data on the clinical features of ENL, which can be incorporated into a definition of ENL and used for outcome measures in treatment studies. PMID:26351858

  19. Measurement of the Thermal Neutron Capture Cross section of 237Np for the Study of Nuclear Transmutation

    International Nuclear Information System (INIS)

    Full text of publication follows: Accurate nuclear data of minor actinides are required for the study of nuclear transmutation of radioactive wastes. The 237Np is one of the most important minor actinides for this study because of its relatively large abundance in irradiated fuels. However, there are apparent discrepancies between the reported neutron capture cross sections of the 237Np for thermal neutrons. History on the measurements of the neutron capture cross section of 237Np for thermal neutrons is briefly presented first. Recent three data measured by a γ ray spectroscopic method are much smaller than those measured by other methods. To deduce the neutron capture cross section by an activation method with γ ray spectroscopy, the relevant γ-ray emission probabilities are used. These decay data could be an origin of the discrepancies on the neutron capture cross section of 237Np. To examine the hypothesis, we measured the relevant γ-ray emission probabilities of 233Pa and 238Np from the ratio of the emission rate to the activity. The obtained emission probabilities are used to correct the thermal neutron capture cross section of 237Np reported previously. The cross section is also independently determined by irradiating 237Np sample in the research reactor of Kyoto University and counting α rays emitted from 237Np and 238Pu with a Si detector. The measured emission probabilities of 233Pa and 238Np, and the neutron capture cross section of 237Np are compared with others from references. The results of the precise decay data explain the discrepancy on the neutron capture cross section of 237Np. Details of the experiments and results will be presented. (authors)

    This study tested whether the pattern of dental services utilization and the reason for the last dental visit mediate the association between educational attainment and dental pain. This is a cross-sectional analysis (n = 1099) based on data from a prospective cohort study in adults, southern Brazil. The mediating effects were assessed by including interaction terms in logistic regression models and by the KHB method, which estimated the direct, mediated, and total effects of education on dental pain. The prevalence of dental pain was 17.5%. Individuals with less than 12 yr of study who visited the dentist to solve dental problems had a 20% higher odds of reporting dental pain than those with 12 or more years of study, who sought the dentist for preventive reasons. Dental services should also focus on preventive measures, especially if less-educated individuals visit the dentist only to treat problems; this may help reduce the frequency of negative oral health outcomes, including dental pain.

  2. A study of the ability of the D0 detector to measure the single jet inclusive cross section

    International Nuclear Information System (INIS)

    The D0 experiment began accumulating data at the Fermilab Tevatron in May of 1992. Protons are collided with antiprotons at √s = 1.8 TeV and an expected peak luminosity of 5 x 1030 cm-2 sec-1. The D0 detector is an all-purpose detector that will have exceptional jet reconstruction capabilities derived from superior calorimetry and nearly 4π angular coverage. One of the many physics measurements that will be made at D0 is the inclusive jet cross section. Comparison of this cross section with theoretical predictions allows us to test the accuracy of the standard model of Quantum Chromodynamics (QCD). This comparison is usually in the form of a measurement of the differential cross section with respect to the transverse energy of the jet. The extended angular coverage of the D0 detector allows measurements of the differential cross section as a function of jet rapidity as well. Recently completed calculations of the next-to-leading-order contribution to the inclusive cross section result in predictions with reduced theoretical errors. In addition, recent fits to data from deep inelastic scattering and single photon experiments further restrict the quark and gluon structure functions of the proton which are necessary in the theoretical predictions of the cross section. It may be that an experimental measurement of the inclusive cross section would favor some of these fits over others. We have studied extensive computer simulations of both the Tevatron and the D0 detector in order to determine D0's ability to reconstruct the inclusive cross section. We present a discussion of this analysis as presently understood

    Full Text Available Systematic reviews (SRs can help decision makers interpret the deluge of published biomedical literature. However, a SR may be of limited use if the methods used to conduct the SR are flawed, and reporting of the SR is incomplete. To our knowledge, since 2004 there has been no cross-sectional study of the prevalence, focus, and completeness of reporting of SRs across different specialties. Therefore, the aim of our study was to investigate the epidemiological and reporting characteristics of a more recent cross-section of SRs.We searched MEDLINE to identify potentially eligible SRs indexed during the month of February 2014. Citations were screened using prespecified eligibility criteria. Epidemiological and reporting characteristics of a random sample of 300 SRs were extracted by one reviewer, with a 10% sample extracted in duplicate. We compared characteristics of Cochrane versus non-Cochrane reviews, and the 2014 sample of SRs versus a 2004 sample of SRs. We identified 682 SRs, suggesting that more than 8,000 SRs are being indexed in MEDLINE annually, corresponding to a 3-fold increase over the last decade. The majority of SRs addressed a therapeutic question and were conducted by authors based in China, the UK, or the US; they included a median of 15 studies involving 2,072 participants. Meta-analysis was performed in 63% of SRs, mostly using standard pairwise methods. Study risk of bias/quality assessment was performed in 70% of SRs but was rarely incorporated into the analysis (16%. Few SRs (7% searched sources of unpublished data, and the risk of publication bias was considered in less than half of SRs. Reporting quality was highly variable; at least a third of SRs did not report use of a SR protocol, eligibility criteria relating to publication status, years of coverage of the search, a full Boolean search logic for at least one database, methods for data extraction, methods for study risk of bias assessment, a primary outcome, an

    Full Text Available Abstract Background The importance of fostering the development of empathy in undergraduate students is continuously emphasized in international recommendations for medical education. Paradoxically, some studies in the North-American context using self-reported measures have found that empathy declines during undergraduate medical training. Empathy is also known to be gender dependent- (highest for female medical students and related to specialty preference - (higher in patient-oriented than technology-oriented specialties. This factor has not been studied in Portuguese medical schools. Methods This is a cross-sectional study of undergraduate medical students on self-rated measures of empathy collected at entrance and at the conclusion of the medical degree, and on the association of empathy measures with gender and specialty preferences in one medical school in Portugal. Empathy was assessed using the Portuguese adaptation of the Jefferson Scale of Physician Empathy-students version (JSPE-spv among three cohorts of undergraduate medical students in the first (N = 356 and last (N = 120 year. The construct validity of JSPE-spv was cross-validated with Principal Component Analysis and Confirmatory Factor Analysis. Reliability was assessed using Cronbach' Alpha. Global JSPE-spv score differences were examined by year of medical school, gender and specialty preferences (people-oriented vs technology-oriented specialties. Results The empathy scores of students in the final year were higher as compared to first year students (F (1,387 = 19.33, p 2p = 0.48; π = 0.99. Female students had higher empathy scores than male students (F (1,387 = 8.82, p 2p = 0.23; π = 0.84. Significant differences in empathy were not found between the students who prefer people-oriented specialties compared to those who favor the technology-oriented specialties (F (1,387 = 2.44, p = .12, ɳ 2p = 0.06; π = 0.06.

    Full Text Available BACKGROUND: In Ethiopia where tuberculosis epidemic remains high, studies that describe hotspots of the disease are unavailable. This study tried to detect the spatial distribution and clustering of smear-positive tuberculosis cases in Dabat, Ethiopia. METHODS AND FINDINGS: A population-based cross sectional study conducted in the Dabat Health and Demographic Surveillance System site from October 2010 to September 2011 identified smear-positive tuberculosis cases. Trained field workers collected demographic and location data from each study participant through house-to-house visits. A spatial scan statistic was used to identify purely spatial and space-time clusters of tuberculosis among permanent residents. Two significant (p<0.001 spatial and space-time clusters were identified in the study district. CONCLUSION: Tuberculosis is concentrated in certain geographic locations in Dabat, Ethiopia. This kind of clustering can be common in the country, so the National Tuberculosis Control Program can be more effective by identifying such clusters and targeting interventions.

    Previous studies indicated that food consumption was associated with Helicobacter pylori infection, but no study has yet investigated the association between Helicobacter pylori infection and dietary patterns. The aim of this study was to evaluate the associations between Helicobacter pylori infection and dietary patterns in Tianjin, China. The final cross-sectional study population comprised 10407 participants. Dietary consumption of participants was assessed via food frequency questionnaire. Factor analysis was used to identify dietary patterns, and Helicobacter pylori infection status was diagnosis by H. pylori urease Immunogold Testing kit. Participants in the highest quartile of the high-carbohydrate/sweet pattern showed a multivariable-adjusted OR (95% CI) of 1.65 (1.27–2.17) for the prevalence of H. pylori infection compared with those in the lowest quartile. The multiple adjusted OR for scores of the extreme quartile of high-protein/cholesterol pattern was 0.75 (95% CI, 0.57–0.98). This study demonstrated that a diet rich in carbohydrates and sweets was positively associated with the prevalence of H. pylori infection; interestingly, a diet characterized by high intake of animal offal, animal blood, fish, seafood, and poultry was associated with a reduction of prevalence of H. pylori infection.

The study was conducted to determine association of occupational stress index (OSI and its aspects with arterial hypertension and lipid disorders using data from a cross-sectional survey of male professional drivers. Methods. The cross-sectional study was performed in 439 professional drivers divided into groups (city- and intercity bus drivers, truck and taxi drivers. The OSI and OSI aspects (high demands, strictness, underload, extrinsic time pressure, noxious exposure, avoidance and conflict were calculated using the standardized questionnaire. Determination of serum lipids, blood pressure (BP and cardiovascular risk factors were done. Results. A significant difference in prevalence of diagnosed hypertension and dyslipidemia was found along with a difference in total OSI and OSI aspects among examined subgroups of drivers. A total OSI was highest in city, high in intercity bus drivers, and the lowest one in truck and taxi drivers (82.79 ± 3.5, 81.28 ± 3.7, 73.75 ± 3.5, 71.61 ± 4.4, respectively; p < 0.01. Similar pattern showed triglycerides (TG, total cholesterol (TC and LDL cholesterol and BP, while HDL-cholesterol showed reverse order (p < 0.01. Logistic regression analyses with multiple OSI aspects adjusted for age and years of exposure showed associations of total OSI with arterial hypertension [OR 5.5; 95% CI (2.24-7.95] and dyslipidemia [OR 1.43 95% CI (1.09-2.80]. Underload was the most important OSI aspect associated with the arterial hypertension [OR 1.18; 95% CI (1.04-2.58] and elevated LDL cholesterol [1.26; 95 CI (1.19-2.1]. A total OSI had a significant association with elevated LDL cholesterol [2.64; 95% CI (1.19- 7.7], triglycerides [OR 3.27; 95% CI (1.20-5.1] and low HDL cholesterol [OR 3.29; 95% CI (1.8-5.8] (p < 0.01.

    Facebook has become a very popular social networking platform today, particularly among adolescents and young adults, profoundly changing the way they communicate and interact. However, some reports have indicated that excessive Facebook use might have detrimental effects on mental health and be associated with certain psychological problems. Because previous findings on the relationship between Facebook addiction and depression were not unambiguous, further investigation was required. The main objective of our study was to examine the potential associations between Internet use, depression, and Facebook intrusion. A total of 672 Facebook users took part in the cross-sectional study. The Facebook Intrusion Questionnaire and the Center for Epidemiologic Studies Depression Scale were used. For collecting the data, the snowball sampling procedure was used. We showed that depression can be a predictor of Facebook intrusion. Our results provides additional evidence that daily Internet use time in minutes, gender, and age are also predictors of Facebook intrusion: that Facebook intrusion can be predicted by being male, young age, and an extensive number of minutes spent online. On the basis of this study, it is possible to conclude that there are certain demographic - variables, such as age, gender, or time spent online - that may help in outlining the profile of a user who may be in danger of becoming addicted to Facebook. This piece of knowledge may serve for prevention purposes. PMID:25963476

However, there are also suggestions in regard to the role of environmental, nutritional, hereditary and work associations for this dramatic increase in myopia. Method: In the present study, the medical students of NRI Medical College were studied for their refractive errors. In addition, their gender distributions, heights, weights, body mass indices were also studied in a batch-wise manner. Information about the refractive errors of eye of their parents are gathered through interviewing these medial students. Results and Conclusion: Our observations suggest that – (a myopia is the predominant refractive errors among the medical students; (b the numbers of myopic students in a batch of medical students are increasing year by year; (c there is no apparent bias towards either gender and (d majority of the parents of myopic medical students are also found to be myopic.

    Objective. Constipation is a prevalent problem in patients with psychiatric disorders; it reduces quality of life and may lead to severe complications. The prevalence distribution of constipation across all psychiatric diagnoses in patients with severe mental illness (SMI) has hardly been studied. The aim of this study is to estimate the association between psychiatric disorders and constipation in SMI inpatients. Methods. The strength of the association between constipation (based on use of laxatives) and DSM-IV psychiatric diagnosis was studied in a cross-sectional study with “adjustment disorders” as the reference group. The association was analyzed using logistic regression. Results. Of the 4728 patients, 20.3% had constipation. In the stratum of patients older than 60 years, all psychiatric categories except for substance related disorders were significantly associated with a higher prevalence of constipation (odds ratios ranging from 3.38 to 6.52), whereas no significant associations were found in the stratum of patients between 18 and 60 years (odds ratios ranging from 1.00 to 2.03). Conclusion. In the elderly, all measured psychiatric diagnoses are strongly associated with an increased prevalence of constipation. Physicians should be extra alert for constipation in SMI patients, independent of specific psychiatric diagnoses. PMID:27034921

    Full Text Available Abstract Background There are number of studies showing that general practice is one of the most stressful workplace among health care workers. Since Baltic States regained independence in 1990, the reform of the health care system took place in which new role and more responsibilities were allocated to general practitioners' in Lithuania. This study aimed to explore the psychosocial stress level among Lithuanian general practitioner's and examine the relationship between psychosocial stress and work characteristics. Methods The cross-sectional study of 300 Lithuanian General practitioners. Psychosocial stress was investigated with a questionnaire based on the Reeder scale. Job demands were investigated with the R. Karasek scale. The analysis included descriptive statistics; interrelationship analysis between characteristics and multivariate logistic regression to estimate odds ratios for each of the independent variables in the model. Results Response rate 66% (N = 197. Our study highlighted highest prevalence of psychosocial stress among widowed, single and female general practitioners. Lowest prevalence of psychosocial stress was among males and older age general practitioners. Psychosocial stress occurs when job demands are high and job decision latitude is low (χ2 = 18,9; p Conclusion One half of respondents suffering from work related psychosocial stress. High psychological workload demands combined with low decision latitude has the greatest impact to stress caseness among GP's. High job demands, high patient load and young age of GP's can be assigned as significant predictors of psychosocial stress among GP's.

    Full Text Available Introduction: Children’s obesity is strong predictor of obesity in adulthood, which increases the incidence of related diseases such as metabolic syndrome. Fatty liver is an abnormality related to metabolic syndrome with higher prevalence in obese children according to some previous studies. This study investigates the presence of Sonographic Fatty Liver (SFL in Iranian obese children in comparison with normal and overweight children. Methods: This was a cross-sectional study on 962 randomly selected children between the ages of 6 to 18 years. The subjects were divided into three groups of normal, overweight and obese based on body mass index (BMI. A questionnaire including demographic and anthropometrical characteristics was filled for each case. To detect the presence of SFL, all the subjects underwent assessment with ultrasonography by a radiologist who was not aware of their BMI. The incidence of SFL was determined on the basis of ultrasonographic diagnosis criteria. Results: The prevalence of SFL in obese children was 54.4% that was significantly higher than overweight (10.5% and normal children (1%. There was no significant difference in prevalence of SFL between sexes. Conclusion: The high rate of detected SFL in obese children in this study suggests that Iranian obese children are at risk of metabolic syndrome. It is therefore necessary to develop some plan to control obesity and its late complications.

    Full Text Available Abstract Background Fever is an extremely common sign in paediatric patients and the most common cause for a child to be taken to the doctor. The literature indicates that physicians and parents have too many misconceptions and conflicting results about fever management. In this study we aim to identify knowledge, attitudes and misconceptions of primary care physicians regarding fever in children. Methods This cross-sectional study was conducted in April-May 2010 involving primary care physicians (n=80. The physicians were surveyed using a self-administered questionnaire. Descriptive statistics were used. Results In our study only 10% of the physicians knew that a body temperature of above 37.2°C according to an auxiliary measurement is defined as fever. Only 26.2% of the physicians took into consideration signs and symptoms other than fever to prescribe antipyretics. 85% of the physicians prescribed antipyretics to control fever or prevent complications of fever especially febrile seizures. Most of the physicians (76.3% in this study reported that the height of fever may be used as an indicator for severe bacterial infection. A great majority of physicians (91.3% stated that they advised parents to alternate the use of ibuprofen and paracetamol. Conclusions There were misconceptions about the management and complications of fever. There is a perceived need to improve the recognition, assessment, and management of fever with regards to underlying illnesses in children.

    Aims and Objectives: This study was conducted to assess the incidence and prevalence of palatal rugae shapes in the male and female populations of Karnataka and Kerala. Materials and Methods: This study consisted of 100 plaster models of each group, which were equally distributed between both the genders, with an age range of 17–23 years. The rugae patterns were recorded by using Thomas and Kotze classification. Correlation between the rugae shape and population as well as the rugae shape and gender were analyzed using chi-square analysis and discriminant function analysis using the Statistical Package for the Social Sciences Version 22 (IBM Corp). Results: Curved, straight, and wavy rugae patterns were the most common in both Kerala and Karnataka sample populations. Chi-square analysis showed significant differences between the populations for the curved pattern; discriminant function analysis showed significant differences between the populations for the curved and straight patterns. Significant gender differences were found in the curved pattern for Karnataka population and in unification patterns for both populations by Chi-square/Fischer exact test. Conclusions: The curved and straight rugae patterns were significantly more frequent in the Kerala population compared to the Karnataka population. Because of the limited sample size of this study, further cross-sectional studies are suggested. PMID:27382539

    Full Text Available Tuberculosis (TB is one of the major health problems in prisons.This study was done to assess the prevalence and determinants of active tuberculosis in Ethiopian prisons.A cross-sectional study was conducted from January 2013 to December 2013 in 13 zonal prisons. All incarcerated inmates underwent TB symptom screening according to WHO criteria. From identified TB-suspects two sputum samples were analyzed using smear microscopy and solid culture. A standardized questionnaire assessing TB risk factors was completed for each TB suspect.765 (4.9% TB suspects were identified among 15,495 inmates. 51 suspects were already on anti-TB treatment (6.67% and 20 (2.8% new culture-confirmed TB cases were identified in the study, resulting in an overall TB prevalence of 458.1/100,000 (95%CI: 350-560/100,000. Risk factors for active TB were alcohol consumption, contact with a TB case before incarceration and no window in prison cell. HIV prevalence was not different between TB suspects and active TB cases. Further, the TB burden in prisons increased with advancing distance from the capital Addis Ababa.The overall TB prevalence in Ethiopian prisons was high and extremely variable among different prisons. TB risk factors related to conditions of prison facilities and the impact of implemented TB control measures need to be further studied in order to improve TB control among inmates.

    Introduction. Medical students experience significant psychological stress and are therefore at higher risk of using sedatives. There are currently no studies describing the prevalence of sedative drug use among medical students in Saudi Arabia. The aim of this study was to evaluate the prevalence and factors associated with sedative drug use among medical students in Saudi Arabia. Materials and Methods. A cross-sectional convenience sampling study gathered data by anonymous questionnaire from students enrolled at the King Saud University College of Medicine in 2011. The questionnaires collected data regarding social and demographic variables, sleep patterns, and the use of stimulant and sedative drugs since enrollment. Sedatives were defined as any pharmaceutical preparations that induce sleep. Results and Discussion. Of the 729 students who returned questionnaires, 17.0% reported sedative drug use at some time since enrollment. Higher academic year, lower grade point average, regular exercise, fewer hours of sleep per day, poorer quality of sleep, and the presence of sleeping disorders were found to be significantly associated with sedative drug use. Conclusions. Further study is required to increase our understanding of sedative drug use patterns in this relatively high-risk group, as such understanding will help in the development of early intervention programs.

    Objectives: To find out the preva-lence of worm infestation and anaemia among pregnant women along with their socio-demographic characteristics, dietary habits and state of personal hygiene and elicit the association, if any, with anemia and worm infestation Materials and methods: A cross-sectional study was carried out among pregnant mothers attending the antenatal clinic at Nasibpur Union Health Center. All antenatal mothers who came for antenatal checkup for the first time to the health centre on two prefixed days of the week during the study period were interviewed. The reports of their stool and haemoglobin examination were followed up. Results: 82% of the pregnant women were suffering from anemia.25% of the study population had worm infestation. Age at marriage, green leafy vegetable, fruit and flesh food intake of at least 4 days a week, use of lemon with food most of the time, avoiding the practice of eating last in the family, handwashing with soap and water before eating and use of footwear outside the house were statically significant with hemoglobin concentration. Only religion and handwashing practice with soap and water before eating had statistically significant association with worm infestation. Conclusion: The study showed that certain protective factors like diet and personal hygiene if addressed at the time of antenatal checkup can reduce the number of cases of anemia significantly.

    Full Text Available Few studies have examined the association between Asian dietary pattern and prediabetes, in particular, the Chinese diet. We conducted a cross-sectional study to identify dietary patterns associated with impaired fasting glucose (IFG which considered a state of prediabetes in Chinese men. The study included 1495 Chinese men aged 20 to 75 years. Information about diet was obtained using an 81-item food frequency questionnaire (FFQ, and 21 predefined food groups were considered in a factor analysis. Three dietary patterns were generated by factor analysis: (1 a vegetables-fruits pattern; (2 an animal offal-dessert pattern; and (3 a white rice-red meat pattern. The multivariate-adjusted odds ratio (OR of IFG for the highest tertile of the animal offal-dessert pattern in comparison with the lowest tertile was 3.15 (95% confidence intervals (CI: 1.87–5.30. The vegetables-fruits dietary pattern was negatively associated with the risk of IFG, but a significant association was observed only in the third tertile. There was no significant association between IFG and the white rice-red meat pattern. Our findings indicated that the vegetables-fruits dietary pattern was inversely associated with IFG, whereas the animal offal-dessert pattern was associated with an increased risk of IFG in Chinese men. Further prospective studies are needed to elucidate the diet-prediabetes relationships.

    Introduction Knowledge on the normative spinal growth is relevant in the prenatal detection of its abnormalities. The present study determines the height, transverse and sagittal diameters, cross sectional area, and volume of individual C1–S5 vertebral bodies. Material and methods Using the methods of computed tomography (CT), digital image analysis, and statistics, the size of C1–S5 vertebral bodies in 55 spontaneously aborted human fetuses aged 17–30 weeks was examined. Results All the 5 examined parameters changed significantly with gestational age (p < 0.01). The mean height of vertebral bodies revealed an increase from the atlas (2.39 ±0.54 mm) to L2 (4.62 ±0.97 mm), stabilized through L3–L4 (4.58 ±0.92 mm, 4.61 ±0.84 mm), and then was decreasing to S5 (0.43 ±1.06 mm). The mean transverse diameter of vertebral bodies was increasing from the atlas (1.20 ±1.96 mm) to L1 (6.24 ±1.46 mm), so as to stabilize through L2–L3 (6.12 ±1.65, 6.12 ±1.61 mm), and finally was decreasing to S5 (0.26 ±0.96 mm). There was an increase in sagittal diameter of vertebral bodies from the atlas (0.82 ±1.34 mm) to T7 (4.76 ±0.85 mm), its stabilization for T8–L4 (4.73 ±0.86 mm, 4.71 ±1.02 mm), and then a decrease in values to S5 (0.21 ±0.75 mm) was observed. The values for cross-sectional area of vertebral bodies were increasing from the atlas (2.95 ±5.25 mm2) to L3 (24.92 ±11.07 mm2), and then started decreasing to S5 (0.48 ±2.09 mm2). The volumetric growth of vertebral bodies was increasing from the atlas (8.60 ±16.40 mm3) to L3 (122.16 ±74.73 mm3), and then was decreasing to S5 (1.60 ±7.00 mm3). Conclusions There is a sharp increase in size of fetal vertebral bodies between the atlas and the axis, and a sharp decrease in size within the sacral spine. In human fetuses the vertebral body growth is characterized by maximum values in sagittal diameter for T7, in transverse diameter for L1, in height for L2, and in both cross-sectional area and volume for

    Full Text Available Background. Asthma and allergic rhinitis are highly prevalent conditions that cause major illness worldwide. This study aimed to assess the association between allergic rhinitis and asthma control in Peruvian school children. Methods. A cross-sectional study was conducted among 256 children with asthma recruited in 5 schools from Lima and Callao cities. The outcome was asthma control assessed by the asthma control test. A score test for trend of odds was used to evaluate the association between allergic rhinitis severity and the prevalence of inadequate asthma control. A generalized linear regression model was used to estimate the adjusted prevalence ratios of inadequate asthma control. Results. Allergic rhinitis was present in 66.4% of the population with asthma. The trend analysis showed a positive association between allergic rhinitis and the probability of inadequate asthma control (. It was associated with an increased prevalence of inadequate asthma control, with adjusted prevalence ratios of 1.53 (95% confidence interval: 1.19−1.98. Conclusion. This study indicates that allergic rhinitis is associated with an inadequate level of asthma control, giving support to the recommendation of evaluating rhinitis to improve asthma control in children.

    Various studies have demonstrated that the five-year graft survival of adolescents after renal transplantation is significantly lower than in children. This may be due to poor adherence to the post-transplant regime in adolescents. It has been shown that nurses can provide support to renal transplanted adolescents with positive effects on their adherence. The aim of this descriptive cross-sectional study was to gain knowledge about important topics of nurses' support to adolescent renal transplant patients. Twenty-seven adolescents between the ages of 12 and 18 years were interviewed and given a questionnaire based on a focus group discussion. Each of the provided 43 topics was rated on its importance. Results showed that responses corresponding to the judgment "very important" ranged from 20 % to 100 %. Information about illness and therapy was given highest priority, followed by the provision of support services as well as information and the support of planning and managing the personal way of living. These topics can be seen as a set of relevant variables that may be used for focused assessment, and for planning of nursing interventions. With regard to clinical practice it is necessary to develop nursing strategies and patient and family education programs based on the results of this study. PMID:19496030

    A cross-sectional school-based survey study (N=13,284; 53% females; mean age 15.8±0.7) of 14-17-year-old adolescents was conducted in seven European countries (Greece, Spain, Poland, Germany, Romania, the Netherlands, and Iceland). The aim of the study was to investigate the prevalence of Internet addictive behavior (IAB) and related psychosocial characteristics among adolescents in the participating countries. In the study, we distinguish two problematic groups: adolescents with IAB, characterized by a loss of control over their Internet use, and adolescents "at risk for IAB," showing fewer or weaker symptoms of IAB. The two groups combined form a group of adolescents with dysfunctional Internet behavior (DIB). About 1% of adolescents exhibited IAB and an additional 12.7% were at risk for IAB; thus, in total, 13.9% displayed DIB. The prevalence of DIB was significantly higher among boys than among girls (15.2% vs. 12.7%, psocial networking, gaming) at least 6 days/week was associated with greater probability of displaying DIB. Multiple logistic regression analysis indicated that DIB was more frequent among adolescents with a lower educational level of the parents, earlier age at first use of the Internet, and greater use of social networking sites and gaming sites. Multiple linear regression analysis showed that externalizing (i.e., behavioral) and internalizing (i.e., emotional) problems were associated with the presence of DIB. PMID:24853789

    Full Text Available Spousal violence against women is very common, yet reliable data concerning its magnitude is lacking. Objectives: To study the prevalence of physical spousal violence and the help-seeking behavior of its victims with respect to certain socio demographic variables, in the three months preceding the survey. Material & Methods: A cross-sectional study consisting of face to face interview of 379 married women, during September to December 2008 was undertaken in Tiswadi Taluka of Goa, India. Results: Spousal violence was reported by 26.6% of the respondents. Factors predisposing the women to victimization included early years of marriage, poor educational status for men and women, working women (OR=3.3; 2.1,5.5, and alcohol consumption by the husband (OR=7; 4.2,11.8. Women with higher monthly income compared to their husbands seemed to be protected (OR=0.28;0.16,0.48. Majority of the victimised women preferred to be silent sufferers. The help seeking behaviour was not proportionate to the severity or the duration of violence but seemed to be influenced by variables like women’s employment, education and income. Conclusion: The study emphasises the role of social factors in perpetuating domestic violence by intimate partner. Change in the social attitude that permits and legitimizes such acts through awareness is the only long lasting panacea.

    Full Text Available The aim of the study was to define an intrauterine growth curve for a population of Nigerian newborn babies. A cross-sectional observational study design was adopted. Weight, length and head circumference were all measured in consecutive singleton deliveries at the University of Ilorin Teaching Hospital over a 3-year period. Gestational age (GA of the babies was estimated from the last menstrual period or first trimester ultrasound. The estimates obtained were clinically validated using the Ballard score. Mean birth weights and percentiles of the weight, length and head circumferences for the respective GA were estimated using the SPSS 15 software package. A total of 5273 babies were recruited for the study with GA ranging from 25-44 weeks. Comparison of the mean birth weights of the various GA with the data from Denver, Colorado, showed that Nigerian babes tended to weigh less at the early GA, although these differences were not statistically significant. Between 26-36 weeks, the average weights of both sexes were similar; however, beyond this time point there was a consistent increase in the average weight of the males over the female babies. Growth curves for Nigerian newborn babies were generated and showed that the mean birth weight of Nigerian preterm babies was lighter than that of babies in Colorado. The impact of these differences on the classification of newborns will require further evaluation.

  20. Systematic study of individual charge-changing cross sections of intermediate-energy secondary beams

    International Nuclear Information System (INIS)

    Highlights: • Precision total and partial charge-changing cross section measurements of medium-mass nuclides were performed. • Systematic reaction data of intermediate-energy heavy-ion beams were obtained. • A significant odd-even effect is found in the partial charge-changing cross sections. -- Abstract: Charge-changing interactions of stable and unstable medium-mass nuclides have been systematically investigated at intermediate energies. Secondary beams ranging from Ar to Ge isotopes produced by projectile fragmentation of 56Fe and 70Ge were irradiated onto a carbon target, and their total and partial charge-changing cross sections were precisely measured. A clear odd–even effect found in the partial charge-changing cross sections monotonically varies as a function of the Z/N ratio among the isotopes, and grows toward the neutron-deficient side. The total charge-changing cross sections are sensitive to the Z number of nuclides, and tend to gradually increase toward the neutron-deficient side in some isotopes

    The target spallation reaction cross sections of neutrons and heavy ions which have not been observed are determined in this paper. The object of this work is to make clear the differences between the spallation reaction cross section of neutron and that of proton by comparing the obtained value of neutron with the known value of proton. To this end, the quasi monochromatic neutron field of 20{approx}50 MeV was developed in 4 cyclotrons, INS, CYRIC, TIARA and RIKEN. The nuclear spallation reaction cross sections of C, Al and Bi were measured in the above field and the distribution of nuclear spallation reaction products in Cu determined by C ion beam of HIMAC. {sup 12}C(n,2n){sup 11}C reaction cross section shows the maximum value of about 20 mb at near 40{approx}50 MeV and then the value gradually decreased to 10 mb. The cross sections of {sup 209}Bi(n,Xn) are shown. The distribution of {sup 61}Cu is lower at the entrance and higher in the depth. (S.Y.)

    Background Epidemiological data from high-income countries suggest that women with hypertensive disorders of pregnancy (HDP) are more likely to develop diabetes later in life. Objective We investigated the association between pre-eclampsia and eclampsia (PE&E) during pregnancy and the risk of diabetes in Indian women. Design Cross-sectional study. Setting India. Methods Data from India's third National Family Health Survey (NFHS-3, 2005–2006), a cross-sectional survey of women aged 15–49 years, are used. Self-reported symptoms suggestive of PE&E were obtained from 39 657 women who had a live birth in the 5 years preceding the survey. The association between PE&E and self-reported diabetes status was assessed using multivariable logistic regression models adjusting for dietary intake, body mass index (BMI), tobacco smoking, alcohol drinking, frequency of TV watching, sociodemographic characteristics and geographic region. Results The prevalence of symptoms suggestive of PE&E in women with diabetes was 1.8% (n=207; 95% CI 1.5 to 2.0; p<0.0001) and 2.1% (n=85; 95% CI 1.8 to 2.3; p<0.0001), respectively, compared with 1.1% (n=304; 95% CI 1.0 to 1.4) and 1.2% (n=426; 95% CI 1.1 to 1.5) in women who did not report any PE&E symptoms. In the multivariable analysis, PE&E was associated with 1.6 times (OR=1.59; 95% CI 1.31 to 1.94; p<0.0001) and 1.4 times (OR=1.36; 95% CI 1.05 to 1.77; p=0.001) higher risk for self-reported diabetes even after controlling for dietary intake, BMI and sociodemographic characteristics. Conclusions HDP is strongly associated with the risk of diabetes in a large nationally representative sample of Indian women. These findings are important for a country which is already tackling the burden of young onset of diabetes in the population. However, longitudinal medical histories and a clinical measurement of diabetes are needed in this low-resource setting. PMID:27496230

    The purpose of the study was to determine factors that attract physician assistants (PAs) to rural settings, and what they found satisfying about their practice and community. A cross-sectional survey design was used. All PAs who were practicing in both nonmetropolitan counties and rural communities in metropolitan counties, in a single midwestern US state, served as the population for the study. A total of 414 usable questionnaires were returned of the 1,072 distributed, a 39% response rate. Factor analysis, descriptive statistics, Pearson's correlation analysis, and robust regression analyses were used. Statistical models were tested to identify antecedents of four job satisfaction factors (satisfaction with professional respect, satisfaction with supervising physician, satisfaction with authority/ autonomy, and satisfaction with workload/salary). The strongest predictor of all four job satisfaction factors was community satisfaction, followed by importance of job practice. Additionally, the four job satisfaction factors had some significant associations with importance of socialization, community importance, practice attributes (years of practice, years in current location, specialty, and facility type), job responsibilities (percentage of patient load not discussed with physician, weekly hours as PA, inpatient visits), and demographics (marital status, race, age, education).

    Full Text Available Recent epidemiological data suggests 13.3% of Hong Kong residents suffered from Common Mental Disorders, most frequently mixed anxiety and depressive disorder. This study examines the weighted prevalence and associated risk factors of depression, anxiety and stress among Hong Kong nurses. A total of 850 nurses were invited to participate in this cross-sectional study. Participants completed the Depression, Anxiety and Stress Scale 21 and multiple logistic regression was used to determine significant relationships between variables. Chronic past-year illness and poor self-perceived mental health were significant correlates of past-week depression, anxiety and stress. It confirmed further positive correlations between depression and divorce, widowhood and separation, job dissatisfaction, disturbance with colleagues, low physical activity levels and sleep problems. Marital status; general medicine; sleep problems, and a lack of leisure significantly correlated with anxiety. Stress was significantly associated with younger age, clinical inexperience, past-year disturbance with colleagues, low physical activity, no leisure and drinking alcohol. Nurses were more depressed, anxious and stressed than the local general population, with over one-third of our respondents classified as subject to these disorders.

    Full Text Available Abstract Background Quality of Life measurements are necessary tools for effectively evaluating health services. In the population of patients afflicted with war-related blindness in Iran, such measurements have yet to be documented and utilized. "The design and implementation of this study involved the determination of a baseline score for QOL in a population of Iranian blinded in the Iraq-Iran war in order to facilitate the design of interventions intended to improve the population's QOL." Methods This was a cross-sectional study of a representative population of 250 war victims blind in both eyes at a 14-day recreational conference. Results Participants had a mean age of 43.20(SD8.34 and their composition was 96.5% male and 3.5% female with a mean SF-36 QOL score of 59.20(SD22.80. An increasing level of education among the participants correlated with a higher QOL score (p = 0.006. The QOL also has a significant correlation to number of injuries (p Conclusions As blind war survivors' age, they will present with a greater set of burdens despite their relatively better QOL in the physical component scale when compared with lower limb amputees. Risk factors of cardiovascular attack such as high blood pressure and hypercholesterolemia were present and need future interventions. Key words Quality of life, blindness, SF36, health

    Full Text Available Objective This study aims to investigate the prevalence of psychiatric disorders, i.e., the presence of signs and symptoms of anxiety and depression in type 1 diabetic patients, as well as to investigate the prevalence of psychiatric disorders in insulin dependent patients. Methods A cross-sectional observational study of 110 diabetic outpatients (mean = 58.3, SD = 14.5; 50 male and 60 female was conducted in a public health clinic with patients diagnosed with diabetes mellitus who were under the medical supervision of an endocrinologist. The patients were evaluated through the Mini International Neuropsychiatric Interview and the Hospital Anxiety and Depression Scale(HADS. Results With respect to anxiety symptoms, we found a prevalence of 60% (n = 66 among patients, while in depression symptoms we found a prevalence of 53.6% (n = 59 concerning the 110 patients evaluated. More specifically, we found 28.2% (n = 31 of patients without depression or anxiety, 13.6% (n = 15 of patients with depression, 16.4% (n = 18 of patients with anxiety and 41.8% (n = 46 of patients with depression combined with anxiety. The most remarkable data were generalized anxiety disorder (22.7%, dysthymia (18.2%, panic disorder (8.2% and social phobia (5.5%. Conclusion The need for accurate assessments about the presence of symptoms related to psychopathology in patients with type 1 diabetes is evident.

    Introduction and Aim. Injecting drug users (IDUs) are amongst the most vulnerable people to acquisition of HIV/AIDS. This study aims to collect information on IDUs and their health seeking behavior in Bangladesh. Design and Methods. A cross-sectional study was conducted among 120 IDUs attending a drug rehabilitation center in Dhaka, Bangladesh. Data were collected on sociodemographics, drug use, health seeking behavior, knowledge of injecting drugs, and sexual behavior. Results. The mean ± SD and median (IQR) age of the participants were 32.5 ± 21.3 and 33 (27-38) years, respectively, with only 9.2% females. Injection buprenorphine was the drug of choice for 40% of participants, and 58% of the participants first started drug use with smoking cannabis. 73.3% of participants shared needles sometimes and 57.5% were willing to use the needle exchange programs. 60% of the participants had no knowledge about the diseases spread by injection. Condom use during the last intercourse with regular partners was 11.7% and with any partners 15.8%. Conclusion. IDUs in Bangladesh are a high-risk group for HIV/AIDS due to lack of knowledge and risky behaviors. Education and interventions specifically aimed at IDUs are needed, because traditional education may not reach IDUs or influence their behavior. PMID:25692067

    Full Text Available Background. Diabetes mellitus and thyroid diseases are common endocrine disorders in the general population and found to exist simultaneously. This study aimed to establish the prevalence of thyroid dysfunction among Omani type 2 diabetics and its association with glycemic control. Methodology. A retrospective cross-sectional randomized primary and secondary care based study of 285 Omani type 2 diabetics, ≥ 30 years of age with known thyroid function. The following parameters were examined: age, sex, duration of diabetes, duration of thyroid disease, thyroid morphology, thyroid function, thyroid antibodies, and the mean glycated hemoglobin (mean HbA1C. The prevalence of thyroid dysfunction was compared to an independent control group of randomly selected healthy individuals with known thyroid function. Results. Thyroid dysfunction was found in 12.6% of the diabetic patients compared to 4.9% in the control group. The prevalence was higher among the diabetic females (86% compared to diabetic males (14%. The commonest thyroid dysfunction among diabetics was overt hypothyroidism (4.6%. Subclinical hypothyroidism was the commonest thyroid dysfunction seen in less controlled diabetics at a mean HbA1c of 7.8 (± 0.7. Conclusion. Screening for thyroid dysfunction in patients with type 2 diabetes mellitus should be routinely performed considering the higher prevalence of thyroid diseases in this group compared to the general population.

    Full Text Available Background: Schizophrenia is a psychosis characterized by delusions and hallucinations occurring in clear consciousness. Studies have shown that the cytokines may modulate dopaminergic metabolism and schizophrenic symptomatology in schizophrenia. Cytokine involvement in periodontal disease is also well documented. To date, however, there has been relatively little research assessing periodontal status of patients with schizophrenia. The present study was therefore mainly intended to understand the exact link, if any, between periodontal disease and schizophrenia. Materials and Methods: A total of 250 schizophrenic patients (140 males and 110 females, between 25 and 55 years of age, were selected from the out patient department of National Institute of Mental Health and Neural Sciences, Bangalore and their periodontal status was assessed as part of this cross-sectional epidemiological survey. Results: ANOVA showed that there was increased evidence of poor periodontal condition, as evidenced by gingival index and plaque index in patients who had been schizophrenic for a longer duration of time (P < 0.001. So also, higher probing pocket depths were found in schizophrenics suffering from a longer period of time than others (P < 0.001. Conclusions: Although oral neglect might be a cause of poor periodontal health in schizophrenics, the possible link between periodontal diseases giving rise to schizophrenia cannot be overlooked due to the presence of cytokine activity which is present both in schizophrenia and periodontal disease.

    Full Text Available Introduction. The prevalence of unhealthy alcohol use among university students is increasing in many countries. Objective. The aim of the study was to investigate alcohol consumption and alcohol-related knowledge, attitudes and risky behaviors among Serbian university students. Methods. The cross-sectional study was carried out at the three state universities from January to June in the academic year 2009/2010 and included 2,285 students of both genders. The students filled out a questionnaire consisting of 70 questions with respect to demographic and socioeconomic characteristics, their lifestyle habits, styles and attitudes, health assessment, as well as exposure to different risk factors. Results. It was found that 77.7% of students drank alcohol occasionally, 4.6% of them consumed it on a daily basis. Friedman’s test (p<0.001 showed that students prefer drinking beer to all other alcoholic beverages. Students in Belgrade and students of Technical faculties are undisputed champions when it comes to how often they drink six or more drinks on a single occasion. Older students in Serbia drink more and get drunk more frequently. Conclusion. A high percentage of Serbian students consume alcohol, and even though they have their first drink at an early age, they generally drink less than students in many other countries.

    Full Text Available Abstract Background Despite the potential impact on treatment adherence and recovery, there is a dearth of data on the extent and correlates of internalized stigma in patients with schizophrenia in low income countries. We conducted a study to determine the extent, domains and correlates of internalized stigma amongst outpatients with schizophrenia in Ethiopia. Methods The study was a cross-sectional facility-based survey conducted at a specialist psychiatric hospital in Addis Ababa, Ethiopia. Consecutive consenting individuals with a diagnosis of schizophrenia were recruited and assessed using an Amharic version of the Internalized Stigma of Mental Illness (ISMI scale. Results Data were collected from 212 individuals, who were mostly single (71.2%, unemployed (70.3% and male (65.1%. Nearly all participants (97.4% expressed agreement to at least one stigma item contained in the ISMI; 46.7% had a moderate to high mean stigma score. Rural residence (OR = 5.67; 95% CI = 2.30, 13.00; p  Conclusion Internalized stigma is a major problem among persons with schizophrenia in this outpatient setting in Ethiopia. Internalized stigma has the potential to substantially affect adherence to medication and is likely to affect the recovery process.

    Full Text Available Abstract Background Integrated delivery methods in healthcare systems have been proposed to confront the increasing complexity in general health care. INTERMED is an empirically derived, observer-rated instrument to measure case complexity. It was intended as a visualized, action-oriented decision-support tool for the early assessment of bio-psychosocial health risks and health needs. This study aims to document the reliability and applicability of the Spanish version of INTERMED in liver transplant patients. Methods Cross-sectional study of patients who had been included in the liver transplant waiting list. Two nurses interviewed the patients with INTERMED, and scored the instrument blind to each other. Kappa and w-kappa, Spearman, Kendall and intraclass correlation coefficients, and Cronbach's alfa were calculated. Results No patient refused the interview. Satisfactory coefficients were documented in most INTERMED items. Kappa was = 0.858 for the categorization of patients as "complex", and 21 of them (48.8% were classified in this category, and were considered to need integrated treatment. Conclusions The Spanish version of INTERMED is reliable. Its applicability in liver transplant patients adds to its generalizability.

    Full Text Available Caring for persons affected with dementia is associated with substantial psychological strain as evidenced by high rates of psychiatric morbidity and high levels of caregiver strain. Dementia care in developing countries will continue to be provided by immediate family members at home and is unlikely to be taken over by institutions due to socio-cultural reasons. This study aims to examine the relationship of selected factors of patients affected with dementia and their caregivers that were associated with the burden and coping of family caregivers. This is a cross sectional study of a long term project by the author (RJ, involves face-to-face interview with questionnaires with family caregivers of patients with dementia. Burden was related to patient’s behavioral problems, gender, family type and the years of care giving. Principal component analysis of Brief Cope revealed 6 major dimensions: acceptance, humor, religion, substance use, behavioral disengagement and self blame as significant coping skills. Care giving was associated with more psychological complaints and a poor quality of life both physical and psychological. Self blame, behavioral disengagement, venting & emotional support emerged as an important variable as the care giver relation differ in the kind of care giving and care giving burden. Results highlight the importance of improving the mixed coping skills in burdened caregivers. Interventions need to designed and tailored to the specific needs of caregivers.

    There are few longitudinal studies of the prevalence of malocclusions and possible self-correction of malocclusions during the development of the dentition. Early intervention might be unnecessary if self-correction of the malocclusion occurs during the transition from the primary to the permanent dentition. Most studies are cross-sectional and in those of longitudinal design, the results are inconsistent and difficult to interpret. Malocclusions may or may not influence the quality of life in children and adolescents. Thus, evaluations of the influence of different malocclusions on quality of life will certainly underpin a broader understanding and knowledge about how malocclusions affect the daily life of young patients. This information may also be important when it comes to assessing the most appropriate time for starting orthodontic treatment, not only from a professional point of view, but also, most importantly, from the patients' perspective. The overall aim of this thesis was therefore to evaluate the prevalence of malocclusions, and to document changes occurring during the development of the dentition, from the primary dentition stage at age 3, through the mixed dentition at age 7, to the early permanent dentition at age 11.5 years. Further aims were to review the current state of knowledge about the impact of malocclusions on oral health related quality of life (OHRQoL) and to investigate how malocclusions affect the quality of life in a cohort of children, aged 11.5 years, whose dental care is provided by the Swedish Public Dental Service.

    Full Text Available Background Hypertension or high blood pressure is a critical condition which can strain the heart, injure blood vessels, leads to augment the risk of heart attack, stroke, kidney problems, and if untreated may cause death. Several herbal approaches have been made to treat hypertensive individuals. Banana is a well known tropical fruit with little known anti hypertensive properties. The objective of this research was to investigate changes in blood pressure after consuming banana among the hypertensive individuals. Methods A cross-sectional study design was used to conduct this research. Data was collected by questionnaire and personal interviewing. Two ripened bananas (Musa acuminata were provided to each subject for 20 days. Blood pressures of the participants were taken before and after the experimentation. Results Most of the subjects were in the age group >60 years followed by 30-40 years and 51-60 years. 57.1% of the respondents were female. Noticeable changes observed in the pre and post experimentation results. Systolic and diastolic blood pressure was significantly decreased after banana consumption. Conclusion Results of this research strongly supports that banana contains phytochemicals, thus its intake significantly reduces blood pressure among hypertensive individuals. However, more clinical studies in human are still required that may provide evidence of efficacy.

    Physical abuse in school has lifelong consequences affecting child health and educational achievements. A study was designed to assess the prevalence of physical abuse experienced by pupils in basic-education schools in Aden, Yemen, and to examine the risk factors associated with it. A cross-sectional study covering 1066 pupils in 7th-9th grades from 8 schools in different districts of Aden governorate were randomly selected. Answering an anonymous self-administered questionnaire, 55.7% of pupils reported physical abuse at least once in their school lifetime (73.2% of males versus 26.6% of females). Teachers were the main perpetrators (45.4%). A statistically significant association was found between physical abuse and sex, age group, family type and father's education. Significant predictors of physical abuse on multivariate regression were male sex (OR=7.89) and extended family type (OR=1.36). Physical abuse in basic-education schools requires serious consideration by educational authorities, families and the community at large. PMID:23882958

    The aim of this study was to assess the potential role of tumor diameter in explaining variations in tumoral invasion and in the initial prognosis for patients with malignant melanoma (MM). This was a multicenter, cross-sectional study that recruited between 2000 and 2009 patients with primary in-situ MM (Tis) and invasive cutaneous MM. Tis and MMs with a Breslow's thickness less than 1 mm (T1) were grouped (Tis-T1) and tumors with a Breslow's thickness 1 mm or more were also analyzed in combination (T2-T4). The tumor size was measured after routine formalin tissue fixation. Primary outcomes were the correlation between Breslow's thickness and tumor size, and the role of tumor size in explaining variations in Breslow's thickness, as assessed by the Pearson correlation test and logistic binary regression with calculation of the odds ratios. A total of 1610 MM patients were included and analyzed. The Pearson correlation between tumor size and Breslow's thickness was 0.42, with a determination coefficient of R2=0.18 (P>0.01). Correlations between tumor size and thickness were stronger in patients aged 30-60 years (r=0.42, R2=0.1764, Pstrength of this association has been moderate. Tumor size explains a low burden of the variation observed in the Breslow's thickness. PMID:26237766

    The goal of this study was to test whether the development of executive function in young children could add to the explained variance in child ritualistic behavior beyond child and maternal traits previously found to have explanatory power. Routinized, ritualistic behavior is common and normative in young children between the ages of 2 and 5, after which it subsides. In this cross-sectional study, maternal reports on 1345 children between the ages of 2 and 6 included child variables such as temperament, fears, and behavioral problems. Mother's characteristics included perfectionism, her attachment style, and trait anxiety. The sample included ultra-orthodox families, an understudied minority, and thus it was possible to compare their ritualistic behavior with that of children from other rearing environments. Ultraorthodox children had more ritualistic behavior than age-matched children. This finding offers support for an environmental influence on level of ritualistic behavior in children. For the entire sample, we found that young children's ritualistic behavior was associated with shy and emotional temperament, fears, pervasive developmental behavioral problems, and that executive function delays in shifting and emotion regulation had an additional contribution. Ritualistic child behavior was only weakly related to maternal variables. The results were consistent with a maturational process for the trajectory of ritualistic behavior, rather than with an environmentally induced behavior. The development of executive function may be the process mediating the decline of ritualistic behavior over development. PMID:25725602

    Health literacy is important in public health and healthcare, particularly in effective communication between patients and health professionals. Although most medical students will eventually work as health professionals after graduation, research on health literacy of medical students is scarce. This study aimed to assess the health literacy level of medical students in Chongqing, China, and its influencing factors. A cross-sectional study was conducted and 1,275 participants (250 males and 1,022 females) who majored in five different disciplines were involved. The Health Literacy Questionnaire was used as the survey tool. The junior students obtained the highest scores, whereas the freshman students had the lowest scores on each scale. The average score of males was higher than that of females except in “feeling understood and supported by healthcare providers,” and the average score of students who reside in urban areas was higher than that of students in rural areas. Moreover, the average score of engineering students was higher than that of medical or health sciences students. Multiple linear regression models (Radj2 = 0.435, P = 0.000) showed that the grade, socioeconomic status, and parent’s highest level of education were positively correlated with health literacy. In conclusion, the health literacy levels of the medical students are insufficient and need improvement. PMID:27050169

    Full Text Available Introduction: Estimation of sex is the ground for an exact identification of unknown human skeletal elements. Methods for sex assessment are based on the existence of morphological features in the skeleton that manifest differently according to sex or statistical differences in skeletal measurements. Due to the specific pattern of ontogeny and age related changes of sterna articular surface during adulthood the clavicle is widely used in the estimation of sex at death and in living people. Objectives: To evolve an easily applied formula to enable the assessment of sex in unknown clavicles and to document the comparative differences between right and left clavicles by using metrical parameters. Materials and Methods: The cross sectional study was conducted in the department of Anatomy, Yenepoya Medical college, Mangalore. The present study was conducted in 50 adult dry clavicle.Maximum clavicular length, maximum breadth of sterna end ,maximum breadth of acromial end and acromial surface area were measured by digital caliper and osteometric board. Results: The maximum length of clavicle ( was statistically significant when compared with the clavicle of females. The other values like breadth of sternal end, breadth of acromial end and acromial surface area were greater in males when compared to females. Conclusion: Determination of sex the clavicle has a great medicolegal importance to the forensic people. And it also help the orthopedic implant manufactures and orthopedic surgeons to decide correct size and shape of plates and intramedullary nails for clavicular fractures in open reduction method.

    Full Text Available There is limited research on the effect of immigration on biological markers of nutrition among children of Mexican origin in the United States. The purpose of this cross-sectional study was to examine data from the Third National Health and Nutrition Examination Survey (NHANES III (1988–1994, on a national and representative sample of 1559 Mexican American children, 4–16 years of age, and assess the associations of country of birth with serum concentrations of carotenoids, vitamin A, and vitamin E. In multiple regression analyses, Mexico-born Mexican American children had significantly higher serum concentrations of α-carotene, β-carotene, β-cryptoxanthin, lutein/zeaxanthin, vitamin A, and vitamin E than their counterparts who were born in the United States after adjustment for age, sex, poverty income ratio, level of education of family reference person, body mass index, total serum cholesterol, serum cotinine, total energy intake, and vitamin/mineral consumption. Our findings confirm evidence for a negative effect of immigration/acculturation on dietary quality in this population. These findings also suggest that immigrant Mexican families should be encouraged to maintain their consumption of fruits and vegetables. Prospective studies are needed to further assess the effects of immigration/acculturation on diet and other health outcomes in children of Mexican origin and immigrants.

    Full Text Available Abstract Background Individual socioeconomic status (SES has been found to be associated with cardiovascular diseases in developed countries, but the association between individual SES and metabolic syndrome (MetS is still unclear in China. The objective of this study was to investigate the association between individual SES and MetS in China. Methods A cross-sectional study of 10054 community residents was performed from May to August 2007 using multistage stratified random sampling. SES was assessed in terms of education, personal monthly income, and household monthly income. The association between SES and MetS was determined by logistic regression models. Results After the adjustments regarding age, marital status, smoking, drinking, physical activity, body mass index (BMI, and community type, odds ratios (ORs for MetS of individuals with education level of 7~12 years and >12 years were 0.87 (95% confidence interval [CI]: 0.75 to 0.99 and 0.83 (95% CI: 0.62 to 0.91 respectively compared with those with education level of Conclusions Gender had an influence on the association between individual SES and MetS. Lower education and household monthly income level were associated with higher risk of MetS among community residents in women, while such association was not significant in men.

    Objectives The Centers for Disease Control and Prevention recommends a reproductive life plan (RLP) to promote individual responsibility for preconception health. The objectives of this study were to determine existing awareness of RLPs in a cohort of reproductive-age adults and to evaluate their knowledge level and beliefs about reproductive life planning. Methods We performed a cross-sectional survey study of adults ages 18-40 years old seeking care at the student health center of a large public university. Participation was voluntary. Survey responses were analyzed by age and gender. Results A total of 559 surveys were collected and analyzed. Only 24 % of participants had heard of an RLP although a majority (62.9 %) agreed that it is important to develop an RLP. Most respondents (85.4 %) preferred to receive information about reproductive life planning from a primary care provider or obstetrician-gynecologist, while only 4.2 % of patients surveyed reported ever being actually asked about an RLP by their healthcare provider. Among those who agreed that an RLP was important, knowledge of specific aspects of an RLP was lacking. Conclusions In our cohort of reproductive-age adults, general health literacy regarding RLPs was poor. Most of the young adults who responded to our survey did not know what an RLP was and even fewer had ever discussed one with their health provider. PMID:26679707

    Full Text Available The aim of this study is to assess whether the dental caries experience is higher in children with an autistic disorder (AD than in normal children. Three schools for autistic children and three standard elementary schools in Istanbul, Turkey, were included in a cross-sectional study. Subjects were orally examined. Socio-demographic information and data about their oral care habits were obtained from their parents from records. Sixty-two children with AD and 301 children without AD were examined. Their ages varied between 6 and 12 years. Children with AD compared to those without AD had lower experience of caries. Logistic regression analysis of DMFT showed that the dental status was positively affected in younger children (OR = 15.57; 95% CI 7.62, 31.80, children from families with high income (OR = 5.42; 95% CI 2.31, 12.75, children brushing teeth regularly (OR = 2.01, 95% CI 1.10, 3.68, children consuming less sugar (OR = 5.01; 95% CI 2.57, 9.76 and in those with AD (OR=3.99; 95% CI 1.56, 10.19. Children with AD had better caries status than children without AD at younger ages.

    Research indicates significant differences between nurse cohorts in many work-related factors. This study compared nurse competence between three generational cohorts comprising the current nursing workforce. The Nurse Competence Scale was used to collect data for this cross-sectional study from 2052 nurses in a university hospital in Finland. Data were analysed statistically. Significant differences were found between nurse cohorts in their competence. The length of work experience had a significant impact on the development of competence. The oldest cohort, with the longest work experience, had the highest competence scores (70.1 on a visual analogue scale), and the youngest had the lowest (59.0). All cohorts were most competent in patient-related nursing tasks, in maintenance of professional competence and in ethical care. Nurses were weakest in the development of nursing practice and the use of evidence-based knowledge. Targeted interventions in teaching-coaching for different nurse generations are needed to ensure the maintenance of nurse competence and high-quality patient care. PMID:24689751

  8. Study of elastic and inelastic neutron cross-sections using time of flight technique

    International Nuclear Information System (INIS)

    High precision neutron scattering data has become increasingly important in the development of nuclear reactors and accelerator systems, astrophysics and space system design, radiation therapy and isotope production, and for shielding considerations. Previous evaluations of the neutron cross-section standards were completed in 1987 and disseminated as NEANDC/INDC and other databases. R-matrix model fits for the light elements and non-model least-squares fits for the heavy elements were the basis of the combined fits for all of the data. Some important reactions and constants are not considered standards, but assist greatly in the determination of the standard cross-sections and reduce their uncertainties. The focus of the present work is to measure elastic and inelastic neutron differential scattering cross-sections for 23Na using Time of Flight Technique for a range of energies with a high accuracy level

    Introduction: Leptospirosis is a zoonotic disease affecting mainly to low income human population. Acute leptospiral infection during pregnancy has been associated with spontaneous abortion and fetal death during the first trimester and the abortion may occur as consequence of systemic failure. Objective: To estimate the frequency of Leptospira interrogans infection in women with spontaneous abortion in the state of Yucatan, Mexico. Methods: A cross sectional study on women with spontaneous abortion was conducted. Serum samples were tested for Leptospirosis by the microaglutination test, to estimate the frequency of the infecting serovar. The indirect ELISA IgM was used to detect recent infection by L. interrogans. DNA was extracted from paraffin-embedded tissue of placenta for PCR detection of L. interrogans. Results: Overall frequency of infection with L. interrogans in the 81 women with abortion was 13.6%. Five of the 12 serovars evaluated were found and included. Two of the 11 women with abortion and positive to microaglutination test were also positive to the ELISA IgM test. None samples were positive for PCR Leptospira diagnosis. Conclusion: two women could be associated with spontaneous abortion due to leptospirosis, because they showed antibodies against L. interrogans in the microaglutination test and ELISA IgM assays. Differences between regions were found with respect to the prevalences of lesptospirosis. PMID:27226658

    Cultural desire is considered to be a prerequisite for developing cultural competence. This study explored cultural desire among student nurses towards Aboriginal peoples and its association with participation in a one-semester unit on Aboriginal health through a cross-sectional survey. Our main outcome, cultural desire, was measured using two items level of agreement with Aboriginal health being an integral component of the nursing curriculum and an expressed interest in Aboriginal health. 220 (74.58%) student nurses completed the survey. Completing the Aboriginal Health and wellbeing unit did not influence students' opinions on inclusion of the unit as part of the nursing curriculum (odds ratio OR 0.73, 95% CI 0.43-1.29) or their overall cultural desire (mean difference = -0.69, 95% CI -1.29 to -0.08, p = 0.026). Students who completed the unit reported a higher understanding of Aboriginal health (OR = 2.35, 95% CI = 1.35-4.08) but lower interest levels in the subject (OR = 0.45, 95% CI: 0.24-0.84). Further research is necessary to explore how and when cultural desire might develop in nurses who are trained in cultural competence particularly in the contexts of post-colonial disparities and political conflict.

    This cross-sectional study examines baccalaureate nursing programs in South Korea to determine how and to what extent patient safety education was delivered, and to assess nursing students' patient safety competency. The Quality and Safety Education for Nurses (QSEN) student evaluation survey and a Patient Safety Competency Self-Evaluation tool were used. We distributed 234 surveys to senior students in four nursing schools; 206 (88%) students responded to the survey. The majority of students (81.6%) reported that they had received patient safety education during coursework. Patient safety education was delivered primarily by lecture rather than during laboratory or simulation sessions. The degree of coverage of QSEN competency and the students' self-reported competency in total and attitude scores showed statistical differences among nursing schools. Students' attitude score was significantly higher than skill and knowledge. Our results confirm the need to revise the nursing curriculum and to use various teaching methods to deliver patient safety education more comprehensively and effectively. Furthermore, there is a need to develop an integrated approach to ensuring students' balanced competency. PMID:26306563

    Objectives To examine young people's awareness of and involvement with tobacco marketing and to determine the association, if any, between this and their smoking behaviour. Design Cross sectional, quantitative survey, part interview and part self completion, administered in respondents' homes. Setting North east England. Participants Stratified random sample of 629 young people aged 15 and 16 years who had “opted in” to research through a postal consent procedure. Results There was a high level of awareness of and involvement in tobacco marketing among the 15-16 year olds sampled in the study: around 95% were aware of advertising and all were aware of some method of point of sale marketing. Awareness of and involvement with tobacco marketing were both significantly associated with being a smoker: for example, 30% (55/185) of smokers had received free gifts through coupons in cigarette packs, compared with 11% (21/199) of non-smokers (Pbrand stretching, and tobacco marketing in general were all independently associated with current smoking status. Conclusions Teenagers are aware of, and are participating in, many forms of tobacco marketing, and both awareness and participation are associated with current smoking status. This suggests that the current voluntary regulations designed to protect young people from smoking are not working, and that statutory regulations are required. PMID:11230063

    Objective: To understand AIDS knowledge and condom use in rural areas, and to analyze the influencing factors of condom use. Methods: This is a cross-sectional study using the cluster-sampling method. 4,800 subjects, randomly selected from six counties in China, were questioned using an anonymous survey. Results: 36% of the subjects knew that tooth extraction could transmit AIDS. 38.4% of the subjects knew that the use of public razors could transmit AIDS. 27.1% of the subjects had used a condom in the last year. The influencing factors of condom use were: sex (OR=1.325), age (OR=1.419), AIDS counseling (OR=2.181), educational level (OR=0.622), location of registered permanent residence (OR=0.732), AIDS knowledge score (OR=0.736), and resident of high AIDS prevalent province (OR=0.354). Conclusion: AIDS knowledge in rural areas is still lacking. The rate of condom use was very low. The main influencing factors of low condom use were being female, elderly, and no AIDS counseling. Higher educational level, registered permanent resident in town, high AIDS knowledge score, and resident of high AIDS prevalent provinces were the propitious factors for condom use.

    There are conflicting data regarding the magnitude and determinants of chronic obstructive pulmonary disease (COPD) risk in farmers.In a cross-sectional study of 917 nonfarming working controls and 3787 farmers aged 40-75 years, we assessed respiratory symptoms, tobacco exposure, job history (without direct exposure measurement) and lung function. COPD was defined by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criterion (post-bronchodilator forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) farmers and controls, respectively (p=0.005), and 3.1% (2.5-3.6%) and 1.5% (0.7-2.3%), respectively, for the LLN criterion (page, sex and smoking status, COPD prevalence was similar in controls and crop farmers. Compared to controls, four job categories had a higher prevalence of COPD according to the GOLD criterion, namely, cattle breeders, swine breeders, poultry breeders and breeders of two or more livestock types. Among cattle breeders, only those from Franche-Comté had higher prevalence of COPD according to both GOLD and LLN criteria.The prevalence of COPD in farmers is higher than in nonfarming working controls, and depends on the farming activity, the region and the criterion used to define COPD.

    Full Text Available Abstract Background C-reactive protein (CRP, a marker of sub-clinical inflammation, is a predictor of future cardiovascular diseases. Dietary habits affect serum CRP level however the relationship between consumption of individual food groups and CRP levels has not been established. Methods This study was designed to explore the relation between food intake and CRP levels in children using data from the cross-sectional 1999-2002 National Health and Nutrition Examination Surveys. CRP level was classified as low, average or high (3.0 mg/L, respectively. Adjusted mean daily intakes of dairy, grains, fruit, vegetables, and meat/other proteins in each CRP category were estimated using multivariate analysis of covariance modeling. The effect modification by age (5-11 years vs. 12-16 years, gender and race/ethnicity was explored. We examined whether total or central body fat (using BMI Z-scores and waist circumference explained any of the observed associations. Results A total of 4,010 children and adolescents had complete information on diet, CRP and all covariates of interest and were included in the analyses. Individuals with high CRP levels had significantly lower intake of grains (p Conclusion Children and adolescents with higher CRP levels had significantly lower intakes of grains and vegetables. The associations between selected childhood dietary patterns and CRP levels seem largely mediated through effects on body composition.

    A cross-sectional study on vaccine coverage and vaccine effectiveness was carried out on a randomized sample of the cohort of schoolchildren born in 1983 attending school in Andorra, prior to the introduction of a Systematic Immunisation Plan that included centralised import and delivery of vaccines to vaccinating clinics, surveillance of the cold-chain during vaccine delivery, and a clearly-defined immunization schedule against diphtheria, tetanus, -pertussis, polio, mumps, rubella and measles. Vaccine coverage was estimated from vaccination card records; history of disease and sociodemographic variables were obtained through a questionnaire to the children's parents and vaccine effectiveness was estimated through serum antibody testing. Vaccine coverage levels for DTP and OPV were 97.8% for both. Protective serum antibody prevalence was correspondingly high except for the polio viruses. The authors suggest that decreased vaccine effectiveness, probably due to poor preservation of the cold chain, might be the cause of this finding. In countries or regions with an otherwise developed organisation of health services, an important issue like this can still be overlooked. PMID:8212915

    Pain is a global health problem, the effects of which range from diminished quality of life to pain management costs and loss of work and productivity. Pain in the head and neck region is defined as a separate entity: orofacial pain (OFP). However, some graduates from dental schools have reported feeling less competent in their ability to diagnose OFP than in other areas of dentistry. The aims of this study were to assess how students at one U.S. dental school had learned about OFP and to identify the teaching methods and venues they would like to see enhanced in the school's OFP curriculum. A cross-sectional four-question survey was administered to 140 dental students in their third and fourth years; the survey had a response rate of 53%. Most students reported having gained their OFP knowledge mainly in dental school, and 91.9% selected didactic courses as the main teaching method in which they had learned about this topic. Clinical education was the main teaching venue these students said they would like to see enhanced in order to gain more knowledge in most forms of OFP; this result aligned with their learning preferences in general. These findings may help dental schools design their OFP curricula to take account of students' preferences as well as practical limitations regarding availability of clinical experiences.

    Cryptochromes are key components of the circadian clocks that generate and maintain seasonal variations. The aim of our study was to analyze the associations of CRY1 and CRY2 genetic variants with the problematicity of seasonal variations, and whether the problematicity of seasonal variations changed during the follow-up of 11 years. Altogether 21 CRY1 and 16 CRY2 single-nucleotide polymorphisms (SNPs) were genotyped and analyzed in 5910 individuals from a Finnish nationwide population-based sample who had filled in the self-report on the seasonal variations in mood and behavior in the year 2000. In the year 2011, 3356 of these individuals filled in the same self-report on the seasonal variations in mood and behavior. Regression models were used to test whether any of the SNPs associated with the problematicity of seasonal variations or with a change in the problematicity from 2000 to 2011. In the longitudinal analysis, CRY2 SNP rs61884508 was protective from worsening of problematicity of seasonal variations. In the cross-sectional analysis, CRY2 SNP rs72902437 showed evidence of association with problematicity of seasonal variations, as did SNP rs1554338 (in the MAPK8IP1 and downstream of CRY2).

    Current recommendations for the prevention of foot ulceration and amputation include screening at-risk individuals by testing for loss of protective sensation at eight sites using 10-g (5.07) nylon monofilaments. Yet measurement of the cutaneous pressure threshold to differentiate one-point from two-point static touch stimuli may allow identification of these at-risk individuals earlier in the clinical course of diabetic neuropathy. The present study tested this hypothesis using a prospective, cross-sectional, multicenter design that included sensibility testing of 496 patients with diabetic neuropathy, 17 of whom had a history of ulceration or amputation. Considering the cutaneous pressure threshold of the 5.07 Semmes-Weinstein nylon monofilament to be equivalent to the 95 g/mm(2) one-point static touch measured using the Pressure-Specified Sensory Device (Sensory Management Services LLC, Baltimore, Maryland), only 3 of these 17 patients with a history of foot ulceration or amputation would have been identified using the Semmes-Weinstein nylon monofilament screening technique. In contrast, using the Pressure-Specified Sensory Device, all 17 patients were identified as having abnormal sensibility, defined as greater than the 99% confidence limit for age, for two-point static touch on the hallux pulp. We conclude that patients at risk for foot ulceration can best be identified by actual measurement of the cutaneous sensibility of the hallux pulp. PMID:16166466

    Measuring the severity and progression of facioscapulohumeral muscular dystrophy (FSHD) is particularly challenging because muscle weakness progresses over long periods of time and can be sporadic. Biomarkers are essential for measuring disease burden and testing treatment strategies. We utilized the sensitive, specific, high-throughput SomaLogic proteomics platform of 1129 proteins to identify proteins with levels that correlate with FSHD severity in a cross-sectional study of two independent cohorts. We discovered biomarkers that correlate with clinical severity and disease burden measured by magnetic resonance imaging. Sixty-eight proteins in the Rochester cohort (n = 48) and 51 proteins in the Seattle cohort (n = 30) had significantly different levels in FSHD-affected individuals when compared with controls (p-value ≤ .005). A subset of these varied by at least 1.5 fold and four biomarkers were significantly elevated in both cohorts. Levels of creatine kinase MM and MB isoforms, carbonic anhydrase III, and troponin I type 2 reliably predicted the disease state and correlated with disease severity. Other novel biomarkers were also discovered that may reveal mechanisms of disease pathology. Assessing the levels of these biomarkers during clinical trials may add significance to other measures of quantifying disease progression or regression. PMID:27185459

    Full Text Available Objective: To assess the nutritional status of adolescent girls in selected villages of the Kolar district. Methods: A community-based cross-sectional study was carried out over a period of two months. 230 adolescent girls of age 10–19 years were selected randomly. Data was collected by interviewing the adolescent girls using predesigned and pre tested Proforma. Various statistical applications like percentiles, mean, standard deviation and proportions were used for analysis of the data. Results: The prevalence of wasting and stunting was 54.79% and 32.17% respectively as per water lows classification and the trend of wasting and stunting declines with the age. The prevalence of thinness was found to be 73.5% as per Indian standards. Prevalence of Anemia was 34.8% percent and it was more among menstruating girls than compared to non-menstruating girls. Anemia prevalence was less among adolescent girls using footwear during defecation than girls not using foot wear. Conclusion: It is concluded that there is a high prevalence of under nutrition among adolescent girls in the rural area of the selected villages. Health education and nutrition interventions are needed on priority basis.

    Social media and electronic news media activity are an important source of information for the general public. Yet, there is a dearth of research exploring the use of Twitter and electronic news outlets during significant worldly events such as the recent Ebola Virus scare. The purpose of this article is to investigate the use of Twitter and electronic news media outlets in communicating Ebola Virus information. A cross-sectional survey of Twitter data and Google News Trend data from 30 September till 29 October, 2014 was conducted. Between 30 September and 29 October, there were approximately 26 million tweets (25,925,152) that contained the word Ebola. The highest number of correlated activity for Twitter and electronic news outlets occurred on 16 October 2014. Other important peaks in Twitter data occurred on 1 October, 6 October, 8 October, and 12 October, 2014. The main influencers of the Twitter feeds were news media outlets. The study reveals a relationship between electronic news media publishing and Twitter activity around significant events such as Ebola. Healthcare organizations should take advantage of the relationship between electronic news media and trending events on social media sites such as Twitter and should work on developing social media campaigns in co-operation with leading electronic news media outlets (e.g. CNN, Yahoo, Reuters) that can have an influence on social media activity.

    Full Text Available Background: Puberty is transformation of the child into an adult. It includes all the events of somatic and mental maturation. Secondary sex characters were also a part of this period. The objective was to assess the pattern of sexual maturation of adolescent school girls in rural India.Methods: This was a community based cross sectional study conducted among school children of Sevanand High school, Mahadula, Nagpur. 322 girls in the age group of 10-18 years were assessed for sexual maturation. The pubertal evaluation was made with reference to Tanner stages and grading was done as per Tanner’s scale. For statistical analysis, median and standard error along with 95% confidence interval (CI were calculated using Epi Info statistical package programme version 6.0 updated 2009. Statistical significance was assessed at a type I error rate of 0.05.Results: We found that pubertal changes appeared earlier in girls. The first to appear was breast development at a median age of 10.40 years. The last to appear was pubic hair development (PH5 at median age 16.87 years, the total time taken for complete sexual maturation being 6.38 years. Median age of menarche was found to be13.18 years.Conclusion: The pattern of sexual maturation in rural adolescent school children revealed that though puberty set in earlier in girls, but took longer time for complete maturation.

    Full Text Available Researches in otherpopulations report a strong association between sexual orientationand depressive symptoms, that is, bisexual, gay, lesbian and unsureabout sexual orientation adolescents refer more depressive symptomsthan heterosexual students. Objective: To determine the associationbetween the sexual orientation and depressive symptomsin adolescent students of a public school at the city of Cartagena, Colombia.Method: A cross-sectional study was designed. This surveyincluded students aged 13-17 year-olds. These students completedin the classroom a questionnaire about health behaviors and theZung´s self-rating depression. Logistic regression was computed forcontrolling confounding variables. Results: A total of 432 students,219 boys and 213 girls, completed successfully the survey. The meanage was 14,6 (SD=1,3, and the mean scholarship was 8,4 (1,5. Atotal of 21,1% of girls and 19,2% of boys considered themselvesbisexuals, gays, lesbians or insure about sexual orientation. Depressivesymptoms were related to sexual orientation exclusivally amonggirls (OR=1,10, 95%CI 1,01-1,18, after controlling confounding factors.Conclusions: Among these adolescent students, depressivesymptoms were associated with the sexual orientation only amonggirls. It is likely that this association could be explained better by the gender than the sexual orientation. Futher investigations are needed in Colombian adolescents students.

    Full Text Available Abstract Background The authors examined factors associated with nutritional resilience/vulnerability among preschoolers in the Gaza Strip in 2007, where political violence and deprivation are widespread. Methods This cross-sectional study was carried out in 2007 using random sampling of kindergartens in order to select 350 preschoolers. Binary logistic regression was used to compare resilient (adequate nutrition and vulnerable (stunted groups with those with moderate nutrition. Results Approximately 37% of the subjects demonstrated nutritional resilience and 15% were vulnerable. Factors associated with nutritional resilience were child younger age, normal birth weight, actively hand- or spoon-feeding when the child was below two years, and residential stability in the past two years. The only factor associated with nutritional vulnerability was lower total score on the mother's General Health Questionnaire, which we interpret as a marker of maternal mental health. Conclusions Children with low-birth weight and older children had worse nutritional resiliency outcomes. Further, poorer outcomes for children were associated with lower maternal mental health status, as well as increased family residential instability. Our results add to the large literature on the pervasive effects of violence and instability on children and underscore the need for resources for early intervention and for the urgent resolution of the Palestinian and other armed conflicts.

    Concerns have been raised about a potential shortage of farm animal vets in the UK. There is no apparent lack of new graduates willing to work with farm animals, but practices report difficulties in recruiting and retaining experienced farm animal vets. Retention of vets in farm animal practice has been identified as a key issue for the sustainability of veterinary businesses and livestock health. A cross-sectional study design was used to identify factors associated with vets remaining in farm animal practice. Data were collected via an online questionnaire covering employment, education, personal background and future plans. The target population was vets with experience of farm animal work in the UK. 380 responses were included in the analysis. Working in a practice where accommodation was provided and an increasing number of years since graduation were associated with significantly lower odds of remaining in farm animal practice, while working in a practice where staff appraisals were carried out; coming from a family with a commercial farm; spending more time on farm work and being on call with an experienced vet in the first job after graduation increased the odds of remaining in farm work. Gender was not significantly associated with retention. PMID:26002092

    Full Text Available This paper explores the effect of social relations and gender-based conflicts on the uptake of HIV testing in the South and Central provinces of Zambia. We conducted a community-based cross-sectional study of 1716 randomly selected individuals. Associations were examined using mixed-effect multivariable logistic regression. A total of 264 men (64% and 268 women (56% had never tested for HIV. The strongest determinants for not being tested were disruptive couple relationships (OR = 2.48 95% CI = 1.00-6.19; tolerance to gender-based violence (OR = 2.10 95% CI = 1.05-4.32 and fear of social rejection (OR = 1.48 95% CI = 1.23-1.80. In the Zambian context, unequal power relationships within the couple and the community seem to play a pivotal role in the decision to test which until now have been largely underestimated. Policies, programs and interventions to rapidly increase HIV testing need to urgently address gender-power inequity in relationships and prevent gender-based violence to reduce the negative impact on the lives of couples and families.

    Full Text Available Background: Nearly 275 million adults use tobacco in India, which contributes substantially to potentially preventable morbidity and mortality. Awareness towards tobacco is increasing steadily but its role towards cessation is questionable. There is little evidence available about quitting behavior in the Uttarakhand region. Aims & Objectives: To assess the quitting behavior among current tobacco users in a rural population of Dehradun. Material and Methods: The study was cross sectional in nature carried out among 993 current tobacco users aged 10 years and above in the field practice area and quitting behavior was assessed using a pretested and predesigned questionnaire. Result: Of the 993 Current tobacco users, 38% and 40% of the current smokers and current smokeless tobacco users respectively had attempted to quit smoking and smokeless tobacco use in the past 12 months. 54.3% of the smokers wanted to quit smoking with majority of male smokers (56.3% willing to quit smoking compared to only 40.5% of female smokers. 36.0% of the smokeless tobacco users wanted to quit smokeless tobacco use where in contrast more female smokeless tobacco users (39.3% wanted to quit smokeless tobacco compared to 33.3% of males. Conclusion: Previous quit attempts were found to be more among males compared to females. The desire to quit smoking tobacco was also found to be more among males as compared to female smokers. More females showed desire to quit smokeless tobacco compared to males.

    Little is known about dissemination strategies that contribute to health information recognition. This study examined (a) health campaign exposure and awareness (slogan and logo recognition); (b) perceived communication channels; (c) differences between perceptions of researcher-developed and enhancement community health information materials; and (d) differences in campaign awareness and communication channels, according to Japanese community demographic characteristics. A cross-sectional survey (N = 508) was conducted in Tokigawa, Japan, in 2013. The Small Change Campaign focused on increasing physical activity and improving dietary habits. Information dissemination was carried out using leaflets, newsletters, posters, website, local public relations magazines, health classes, events, and online newsletters. The participants completed a survey assessing their campaign awareness (i.e., slogan and logo) and exposure to the informational materials presented during the campaign. Fewer than half (45.4%) knew the slogan, and only 24.4% were aware of the logo. Public relations magazines, leaflets, and newsletters were significantly better-perceived health communication channels. Researcher-developed and enhancement community health information materials were equally recognized (p = .34, w = .08). Furthermore, women and those who were employed were significantly more aware of the slogan, logo, and communication materials. Further research should explore effective communication strategies for community-based health promotion intervention via randomized control trials. PMID:25869407

  11. Smoking dependence and common psychiatric disorders in medical students: Cross-sectional study

    International Nuclear Information System (INIS)

    Objectives: Exploring the variable effect of the degree of smoking dependence on the level of anxiety and depression symptoms among medical students. Methodology: This cross-section study, conducted in the Department of Pharmacology, College of Medicine, Al-Mustansiriya University, Baghdad-Iraq from December 2010 to May 2011, involving 300 medical students selected by cluster random sampling techniques. Those students completed the Hamilton rating scale for anxiety, Zung self-report depression scale and the Fagerstrom test for nicotine dependence with a value of six or more regarded as heavy smokers, and a value less than six considered as light smokers. Results: The response rate was 89%, heavy smokers were significantly older and start smoking at an earlier age than non- and light smokers (p=0.001). Heavy smokers associated with high chance of depressive symptoms in comparison with non-smokers (OR=4.8, C.I.=1.752-13.677) and light smokers (OR=4.2, C.I.=1.042-17.161). Regarding anxiety symptoms, heavy smokers demonstrate high chance of anxiety symptoms in comparison with non-smokers (OR=5.2, C.I.=1.826-15.176), and light smokers (OR=4.5, C.I.=1.318-15.526). Conclusions: Heavy smokers differ from non- and light smokers, associated with high risk of anxiety and depression, therefore heavy smoking tends to deteriorate rather than ameliorate these symptoms.

    Full Text Available Hypertension is the most common medical problem encountered during pregnancy, complicating 2-3% of pregnancies. High blood pressure (BP with diastolic BP ≥ 90 mm Hg and/or systolic BP ≥ 140 mm Hg arising after week 22 of pregnancy and resolving after delivery is defined as gestational hypertension (GHY. The aim of this cross-sectional study was to investigate whether occupational and/or environmental exposure to organophosphorus (OP pesticide affects GHY. Women at approximately 22 weeks of gestation were recruited. OP pesticide exposure in the first trimester of pregnancy was classified into four categories: no exposure, indirect exposure, domestic exposure, and occupational exposure. Application of the exclusion criteria left 2203 participants (mean age 30.4 ± 11.6 years. Data analysis showed that in women with indirect OP pesticide exposure the incidence of GHY was slightly higher than that in the world population, whereas domestic exposure involved a 7% increase and occupational exposure a 12% increase. Analysis of the pesticides used by participants highlighted a possible role for malathion and diazinon (adjusted OR 1.09 and 1.14, resp.. Further investigation of exposed workers and the general population is clearly warranted given the broad diffusion of OP pesticides and their possible public health impact, maybe by including a wider range of health outcomes.

    Full Text Available Abstract Background Parents and Health Care Workers have traditionally attributed a variety of symptoms to teething in young children. Some of these symptoms may however connote underlying serious medical condition in a child. There is little evidence to support these beliefs despite their implications on management of a symptomatic teething child. This study therefore seeks determine the beliefs and problems mothers associate with teething in Enugu, South-east Nigeria. Findings A cross-sectional survey involving sixty mothers presenting at a Children's clinic in Enugu metropolis using questionnaire. More than 90% of the respondents thought that babies can experience medical problems as a result of teething. The commonest medical problems perceived to be associated with teething were fever (71.7%, loose stools (58.3% and vomiting (35%. Conclusion Mothers still associate a variety of symptoms of childhood illnesses to teething and this association is not evidence based and could lead to delayed interventions, increased morbidity and mortality of children. It is important therefore that mothers and health workers caring for young children are educated on the need to seek prompt medical attentions in a symptomatic child.

    To characterise the Emergency Department (ED) prevalence of cellulitis, factors predicting oral antibiotic therapy and the utility of the Clinical Resource Efficiency Support Team (CREST) guideline in predicting patient management in the ED setting, a prospective, cross-sectional study of consecutive adult patients presenting to 3 Irish EDs was performed. The overall prevalence of cellulitis was 12 per 1,000 ED visits. Of 59 patients enrolled, 45.8% were discharged. Predictors of treatment with oral antibiotics were: CREST, Class 1 allocation (odds ratio (OR) 6.81, 95% Cl =1.5-30.1, p=0.012), patient self-referral (OR= 6.2, 95% Cl 1.9- 20.0, p=0.03) and symptom duration longer than 48 hours (OR 1.2, 95% Cl = 1.0-1.5,p=0.049). In conflict with guideline recommendation, 43% of patients in CREST Class 1 received IV therapy. Treatment with oral antibiotics was predicted by CREST Class 1 allocation, self-referral, symptom duration of more than 48 hours and absence of pre-EO antibiotic therapy.

    Full Text Available Introduction: Nurses' professional competence is a crucial factor in clinical practice. Systematic evaluation of nurses’ competence and its related factors are essential for enhancing the quality of nursing care. This study aimed to assess the nurses’ competence level and its possible relationship with their personality and emotional intelligence. Methods: Using a cross-sectional survey design, three instruments including Nurse Competence Scale, short form of Schutte Self Report Emotional Intelligence Test, and the short 10-item version of Big Five Factor Inventory, were administered simultaneously to a randomized stratified sample of 220 nurses working in hospitals affiliated to Mashhad University of Medical Sciences. Data analysis was performed using SPSS 11.5. Results: Majority of nurses rated themselves as "good" and "very good", with the highest scores in "managing situations" and "work role" dimensions of nurse competence. A relatively similar pattern of scores was seen in competence dimensions, personality and emotional intelligence, among male and female nurses. Emotional intelligence and personality scores showed a significant relationship with nurses’ competence, explaining almost 20% of variations in nurse competence scores. Conclusion: Iranian nurses evaluated their overall professional competence at similar level of the nurses in other countries. Knowledge about the nurses’ competence level and its related factors, including personality and emotional intelligence, may help nurse managers in enhancing nurses' professional competence through appropriate task assignments and conducting in-service educational programs, thus improving the health status of patients.

  17. Benchmark study on neutron cross sections based on pulsed sphere experiment

    International Nuclear Information System (INIS)

    Benchmark validation of neutron cross sections was performed by comparing theoretical calculated leakage spectra with measured ones by means of pulsed sphere experiment conducted at OKTAVIAN of Osaka University, FZK, German and IPPE Obninsk, Russia. It was found out that the nuclear data of Be in both JENDL Fusion File and ENDF/B-VI had similar trend in each experiment. However, there exists some discrepancy among the three different experiments, which suggests further study is needed to validate Be nuclear data. Calculated spectra for Li, Cr, Mn, Cu, Zr, Nb and Mo using JENDL Fusion File predict the experiment fairly well. However, for LiF, (CF2)n, Si, Ti, Co and W, the calculated spectra are not in good agreement with the measurement. The prediction using FENDL-1.0 data gives NN agreement in case of Li, Cr, Mn, Cu and Mo, whereas in other case, the prediction gives insufficient result. The analysis of Fe and Pb experiment conducted at IPPE Obninsk showed that Fe data in JENDL Fusion File and JENDL-3.2 were much better than FENDL/E-1.0. Pb data in JENDL Fusion File appeared to have been much improved as compared with JENDL-3.2 evaluation. (author)

    Full Text Available Abstract Background Tissue injury due to hypoxia and/or free radicals is common in a variety of disease processes. This cross-sectional study aimed to investigate effect of chronic kidney diseases (CKD and hemodialysis (HD on hypoxia and oxidative stress biomarkers. Methods Forty pediatric patients with CKD on HD and 20 healthy children were recruited. Plasma hypoxia induced factor-1α (HIF-1α, vascular endothelial growth factor (VEGF were measured by specific ELISA kits while, total antioxidant capacity (TAC, total peroxide (TPX, pyruvate and lactate by enzymatic/chemical colorimetric methods. Oxidative stress index (OSI and lactate/pyruvate (L/P ratio were calculated. Results TAC was significantly lower while TPX, OSI and VEGF were higher in patients at before- and after-dialysis session than controls. Lactate and HIF-1α levels were significantly higher at before-dialysis session than controls. Before dialysis, TAC and L/P ratio were lower than after-dialysis. In before-dialysis session, VEGF correlated positively with pyruvate, HIF-1α and OSI correlated positively with TPX, but, negatively with TAC. In after-dialysis session, HIF-1α correlated negatively with TPX and OSI; while, OSI correlated positively with TPX. Conclusions CKD patients succumb considerable tissue hypoxia with oxidative stress. Hemodialysis ameliorated hypoxia but lowered antioxidants as evidenced by decreased levels of HIF-1α and TAC at before- compared to after-dialysis levels.

    Inequality in access to quality healthcare is a major health policy challenge in many low- and middle-income countries. This study aimed to identify the major sources of inequity in healthcare utilization using a population-based household survey from urban Nepal. A cross-sectional survey was conducted covering 9177 individuals residing in 1997 households in five municipalities of Kathmandu valley between 2011 and 2012. The concentration index was calculated and a decomposition method was used to measure inequality in healthcare utilization, along with a horizontal inequity index (HI) to estimate socioeconomic inequalities in healthcare utilization. Results showed a significant pro-rich distribution of general healthcare utilization in all service providers (Concentration Index: 0.062, P inequalities in the level of household economic status (percentage contribution: 67.8%) and in the self-reported prevalence of non-communicable diseases such as hypertension (36.7%) and diabetes (14.4%). Despite the provision of free services by public healthcare providers, our analysis found no evidence of the poor making more use of public health services (Concentration Index: 0.041, P = 0.094). Interventions to reduce the household economic burden of major illnesses, coupled with improvement in the management of public health facilities, warrant further attention by policy-makers.

    Full Text Available Objective.  To identify the factors that affect adherence to medication among older persons aged 65 and older in the Arab sector using an extended Theory of Reasoned Action. Design, Sample: A Cross-sectional questionnaire survey was conducted among convenience sample of 200 older persons in Israel aged 65 and older from the Israeli Arab sector who use prescription drugs. Measurments: The questionnaire was prepared by the researchers based on the literature review and the extended research model. Results. Research findings indicate that 80.5% of respondents fully adhere to medication. Respondents believe that medication is important and must be adhered to and they attribute much significance to the effect of significant others (physician, children on medication adherence. Moreover, adherence was found to decline with the rise in number of medications. Adherence also rises with lower functioning of respondents, who consequently receive more assistance with daily activities.  Conclusion.  The present study supports the use of an extended psychosocial theory for identifying factors affecting the medication adherence of older Arabs. It is very important to assess older persons' adherence to medication. Reevaluation of the number of medications prescribed, sources of assistance, and guidance for proper administration of medications, should be considered.

    Headache attributed to ingestion of a cold stimulus (ICHD-3 beta 4.5.1) is also known as ice cream headache (ICH). This cross-sectional epidemiological study included 283 students (10-14-year-olds) attending a grammar school in Germany, their parents (n = 401), and 41 teachers. A self-administered questionnaire was used to analyze the prevalence and characteristics of ICH based on the ICHD classification. Additionally, the association between ICH and other headaches was investigated in students and parents. Prevalence of ICH in students was 62 % without gender difference. In adults, only 36 % of females and 22 % of males reported ICH. There was an increased risk for ICH in students when mother (OR 10.7) or father (OR 8.4) had ICH. Other headaches in parents had no influence on the prevalence of ICH in students. However, in the groups of students and parents itself there was a highly significant association between ICH and other headaches (students: OR 2.4, mothers: OR 2.9, fathers: OR 6.8). There was a decreased risk for ICH when parents and students had no headache at all (OR history seems to be a protective factor for ICH. PMID:27039390

    Full Text Available Abstract Background Breastfeeding is considered the ideal method of infant feeding for at least the first six months of life. This study aimed to compare breastfeeding intention between Syrian and Jordanian women and determine factors associated with breastfeeding intention among pregnant women in these two countries. Methods A cross-sectional design was used to collect data from1200 pregnant women aged 18 years and above (600 participants from each country. A self- administered questionnaire was used to collect data on socio-demographic characteristics and breastfeeding intention. Results Intention to breastfeed was reported by 77.2% of Syrian and 76.2% of Jordanian pregnant women. There was no significant difference in intention to breastfeed between Syrian women and Jordanian women. In both countries, women with a more positive attitude to breastfeeding, women with previous breastfeeding experience and women with supportive partners were more likely to intend to breastfeed. Syrian women with a monthly family income of more than US$200, younger than 25 and primiparous or having one child were more likely to report an intention to breastfeed their infants. Jordanian women with an education level of less than high school and not living with their family-in-law were more likely to intend to breastfeed. Conclusions In Syria and Jordan, a more positive attitude to breastfeeding, previous breastfeeding experience and presence of supportive husbands are associated with intention to breastfeed. These factors should be considered when planning programs designed to promote breastfeeding in these two countries.

    Full Text Available "Background: Nutritional status of elderly is an important determinant of their health and quality of life. Elderly people are more vulnerable for nutritional insults as compared to adults. Undernutrition among elderly people is becoming significantly high regardless of the progress on health care system. This study was aimed to assess prevalence and associated factors of under nutrition among elderly people in Gondar town, Northwest Ethiopia. Methods: A community based cross-sectional study was conducted. Two stage cluster sampling technique was used to select study participants. A total of 757 subjects were included in this study for nutritional status assessment. The predictive value of the variable to Undernutrition was identified by bivariate and multiple logistic regression analysis. Results: The prevalence of undernutrition was approximately 21.9% in elderly people included in this study. Multiple analysis found that unable to read and write [AOR 2.7 95% CI (1.7-5.2], being female [AOR 3.0 95% CI (1.6-5.4], being older [AOR 38.1 95% CI (15.0-96.9], being poor [AOR 1.8 95% CI (1.0-3.2] and have poor dietary diversity score [AOR 3.7 95% CI (1.8-7.6] are independently and negatively associated with nutritional status of elderly people. Conclusion and recommendation: This study indicated high prevalence of undernutrition among elderly people in Northwest Ethiopia. Old age range, gender, educational status, dietary diversity score and wealth index were found to be the factors affecting under nutrition of elderly people. Nutrition intervention and educations focusing on very old and female elderly people in improving health care and dietary practice are highly recommended in this study area. "

    Full Text Available Many previous studies have shown that meditation practice has a positive impact on cognitive and non-cognitive functioning, which are related to job performance. Thus, the aims of this study were to (1 estimate the prevalence of meditation practice, (2 identify the characteristics of individuals who practice meditation, and (3 examine the association between meditation practice and job performance. Two population-based, cross-sectional surveys were conducted. In study 1, we examined the prevalence of meditation practice and the characteristics of the persons practicing meditation; in Study 2, we examined the association between meditation practice and job performance. The outcome variables included work engagement, subjective job performance, and job satisfaction. The Utrecht Work Engagement Scale was used to assess work engagement, the World Health Organization Health and Work Performance Questionnaire (HPQ was used to measure subjective job performance, and a scale developed by the Japanese government was used to assess job satisfaction. Hierarchical multiple regression analyses were used in Study 2. Demographic characteristics and behavioral risk factors were included as covariates in the analyses. The results of Study 1 indicated that 3.9% of persons surveyed (n = 30,665 practiced meditation; these individuals were younger and had a higher education, higher household income, higher stress level, and lower body mass index than those who did not practice meditation. The results of Study 2 (n = 1,470 indicated that meditation practice was significantly predictive of work engagement (β = 0.112, p < .001, subjective job performance (β = 0.116, p < .001, and job satisfaction (β = 0.079, p = .002, even after adjusting for covariates (β = 0.083, p < .001; β = 0.104, p < .001; β = 0.060, p = .015, respectively. The results indicate that meditation practice may positively influence job performance, including job satisfaction, subjective job

    Full Text Available Amblyopia is that condition in which there is deficiency of form or spatial vision sense resulting in the reduction of visual acuity of greater than two lines between the eyes or an absolute reduction in acuity below 6/9 either eye in Snellen's Vision Chart which cannot be corrected by refraction and cannot be attributed directly to the effect of any structural abnormality of the eye or the posterior visual pathway defects The aim of our study is to study the prevalence of amblyopia and different types of amblyopia in children between 6 – 14 years of age This prospective cross sectional study done in tertiary care centre over period of 2years. 2700 children were screened in this study out of which 54 children were found to be amblyopic. Children aged between 6 years and 14 years of age, with no previous history of strabismus surgery, with corrected or uncorrected refractive errors were included in study. RESULTS: Amblyopia was more common in male (63.79% than female children. It was lower in urban children (32.76% than in rural children (67.21%. This is because of the lack of awareness among the rural population to have regular eye check-ups. Monocular amblyopic 40(68.96% cases were common than binocular 18(21.04% cases. The most common cause of ambylopia in our study were anisometropic (36.20%, strabismic (25.86%, ametropic (12.06%, merdionic and visual deprivation (6.89%. Hypermetropia 18(46.15% was more common refractive error associated with amblyopia compared to myopia 10(25.64 and astigmatism 11(18.20%. In strabismic amblyopia (25.86%, exotropia 8 patients (53.33% are more frequent than esotropia 6 patients (40% and hypertropia 1patient (6.66 CONCLUSION: Early diagnosis and treatment of ametropias can minimize permanent loss of vision by amblyopia. Those at greater risks are children of preschool and school going ages.

    Full Text Available BACKGROUND: Smoking, drinking and chewing tobacco product, common habits in India have been positively associated with oral lesions. No study has been conducted in this part of Tamilnadu regarding the prevalence of oral lesions in relation to habits. METHODS: A hospital based cross-sectional study was carried out at Ragas Dental College, Chennai. Already existing data of two thousand and seventeen consecutive patients from sub-urban areas of Chennai, who attended the outpatient department, at Ragas Dental College, for dental complaints during a period of three months in 2004, who underwent oral examination and interviewer based questionnaire was used. RESULTS: Oral soft tissue lesions were found in 4.1% of the study subjects. The prevalence of leukoplakia, OSF and oral lichen planus was 0.59%, 0.55%, and 0.15% respectively. The prevalence of smoking, drinking alcoholic beverages and chewing was 15.02%, 8.78% and 6.99% respectively. Smoking and chewing were significant predictors of leukoplakia in this population. DISCUSSION: The prevalence of leukoplakia, OSF and oral lichen planus in our study population is similar to those found in other populations. The prevalence of consumption of alcoholic beverages in our study population was higher when compared to the Indian National Sample Survey study. However the prevalence of smoking and chewing was found to be lower. Smokers were more likely to develop smoker′s melanosis compared to other lesions. Among those who consumed alcoholic beverages alone, the prevalence of leukoplakia was higher compared to other lesions. OSF was the most prevalent lesion among those who chewed panmasala or gutkha or betel quid with or without tobacco.

    Objectives To evaluate the risk of bias tool, introduced by the Cochrane Collaboration for assessing the internal validity of randomised trials, for inter-rater agreement, concurrent validity compared with the Jadad scale and Schulz approach to allocation concealment, and the relation between risk of bias and effect estimates. Design Cross sectional study. Study sample 163 trials in children. Main outcome measures Inter-rater agreement between reviewers assessing trials using the risk of bias tool (weighted κ), time to apply the risk of bias tool compared with other approaches to quality assessment (paired t test), degree of correlation for overall risk compared with overall quality scores (Kendall’s τ statistic), and magnitude of effect estimates for studies classified as being at high, unclear, or low risk of bias (metaregression). Results Inter-rater agreement on individual domains of the risk of bias tool ranged from slight (κ=0.13) to substantial (κ=0.74). The mean time to complete the risk of bias tool was significantly longer than for the Jadad scale and Schulz approach, individually or combined (8.8 minutes (SD 2.2) per study v 2.0 (SD 0.8), P<0.001). There was low correlation between risk of bias overall compared with the Jadad scores (P=0.395) and Schulz approach (P=0.064). Effect sizes differed between studies assessed as being at high or unclear risk of bias (0.52) compared with those at low risk (0.23). Conclusions Inter-rater agreement varied across domains of the risk of bias tool. Generally, agreement was poorer for those items that required more judgment. There was low correlation between assessments of overall risk of bias and two common approaches to quality assessment: the Jadad scale and Schulz approach to allocation concealment. Overall risk of bias as assessed by the risk of bias tool differentiated effect estimates, with more conservative estimates for studies at low risk. PMID:19841007

    Full Text Available Abstract Background Alcohol use is an important risk factor for morbidity, mortality and social harm among adolescents. There is paucity of data on alcohol use among high school students in Ethiopia. This study aimed to determine the prevalence and factors associated with alcohol use among high school students in Ethiopia Methods A cross-sectional study was conducted to assess the prevalence of alcohol use and its predictors among high school students in eastern Ethiopia in April 2010. A sample of students was taken from all schools based on their enrollment size. Prevalence estimates and their 95% confidence intervals were calculated. Logistic regression was performed to adjust and examine associations. Results A total of 1721 students participated in the study. The mean age of the study population was 16.4 (SD 1.6 years. A total of 372 (22.2%; 95% CI 20.2 - 24.2% students drink alcohol. Of these, 118 (31.7% were females and 254 (68.3 males. Multivariate analysis indicated that males (OR 2.09; 95% CI 1.45-3.00, older age (OR 1.16; 95% CI 1.01-1.34, having friends who used alcohol (OR 10.09; 95% CI 6.84-14.89 and living with people who use alcohol (OR 2.77; 95% CI 1.89-4.07 increased the odds of drinking among students. Conclusion There is a high level of alcohol use among high school students in the study area. Involvement of parents, health workers and school authorities are necessary to avert the problem. Specifically, their involvement in awareness campaigns and peer education training are important to encourage students to avoid alcohol use.

    Full Text Available Abstract Background Sleep is an important physiological process for humans. University students in most resource limited countries often report poor sleep quality due to changing social opportunities and increasing academic demands. However, sleep quality among university students has not been studied in Ethiopia. Thus, this study assessed sleep quality and its demographic and psychological correlates among university students. Methods A cross-sectional survey was conducted in two universities in Ethiopia. Multistage sampling procedures were used to enroll 2,817 students into the study. A self-administered structured questionnaire including the Pittsburgh Sleep Quality Index (PSQI, the Depression Anxiety Stress Scale-21, the Perceived Stress Scale (PSS and selected modules of the World Health Organization STEPS instrument was used for the study. This research included 2,551 students. Frequency, median, mean with standard deviation and 95% confidence interval were used to characterize sleep quality and other variables. Analysis of variance and binary logistic regression procedures were also used. Result The prevalence of poor sleep quality (total PSQI score > 5 was 55.8% (1,424. Female students (adjusted odds ratio (AOR 1.23; 95% CI: 1.00, 1.57, second year (AOR 2.91; 95% CI: 2.1, 4.02 and third year students (AOR 2.25; 95% CI 1.62, 3.12 had statistically significant higher odds of poor sleep quality. Perceived stress level and symptoms of depression and anxiety were strongly associated with sleep quality. Conclusion A substantial proportion of university students are affected by poor sleep quality. If our results are confirmed in prospective studies, health promotion and educational programs for students should emphasize the importance of sleep and mental health.

    Background Statins are a major group of drugs that reduces LDL-C levels, which are proven to have other beneficial effects such as preventing coronary events. The objective of this study was to evaluate oxidative stress and select novel coronary artery disease risk factors among coronary artery disease patients on statins. Methods In this observational, cross-sectional study, we compared total cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol, apolipoprotein B, lipoprotein (a), homocysteine, reduced glutathione, glutathione peroxidase, superoxide dismutase, ascorbic acid, malondialdehyde and oxidized LDL among male coronary artery disease patients on statin therapy (group 2, n = 151) with sex-matched, diabetic patients (group 3, n = 80) as well as healthy controls (group 1, n = 84). Results Total cholesterol, triglycerides, HDL-cholesterol and LDL-cholesterol were significantly lower among subjects of group 2 compared to other two groups. The novel risk factors studied did not differ significantly between groups, except for a higher homocysteine level among group 2 subjects compared to the other two groups. Elevated oxidative stress, indicated by lower reduced glutathione, glutathione peroxidase, and ascorbic acid as well as higher malondialdehyde and oxidized LDL was observed among group 2 subjects. Triglycerides, HDL-cholesterol, ascorbic acid and malondialdehyde were found to be independent predictors for coronary artery disease among this study population. Conclusions Though coronary artery disease subjects had healthy lipid profile, oxidative stress, a recognized risk factor for coronary events, was still elevated among this patient group. Novel risk factors were not found to be major predictors for coronary artery disease among the study subjects. PMID:26138179

    Full Text Available Objectives: This study aimed to determine the prevalence of depression, anxiety and stress among Saudi Arabian dermatology patients and to assess associations with sociodemographic and clinical characteristics. Methods: This cross-sectional study was conducted among 300 consecutive dermatology patients visiting King Abdulaziz Medical City in Riyadh, Saudi Arabia, in August 2015. The Arabic version of the Depression, Anxiety and Stress Scale was used to screen for symptoms of depression, anxiety and stress. Quality of life (QOL was assessed using the Dermatology Life Quality Index. Results: A total of 254 dermatology patients participated in the study (response rate: 84.7%. The prevalence of depression, anxiety and stress was 12.6%, 22.1% and 7.5%, respectively. The presence of at least one of these negative emotional states was noted among 24.4% of the cohort (95% confidence interval: 19.3–30.2%. Depression was significantly higher among subjects who lacked family support (26.5% versus 10.7%; P = 0.006 while anxiety was less common among patients who engaged in physical exercise (14.5% versus 29.4%; P = 0.005. According to the multivariate logistic regression analysis, poor QOL and a lack of family support were significant predictors of a negative emotional state. Conclusion: Almost a quarter of the studied Saudi Arabian dermatology patients were found to suffer from at least one negative emotional state. A lack of family support and poor QOL were the primary factors associated with a negative emotional state. Interventional studies are needed to examine the effects of social and family support on psychological conditions among Saudi Arabian dermatology patients.

    Full Text Available Abstract Background The most common geriatric psychiatric disorder is depression. The role of family systems in depression among the elderly has not been studied extensively. It has been suggested that urbanization promotes nucleation of family systems and a decrease in care and support for the elderly. We conducted this study in Karachi, a large urban city of Pakistan, to determine the relationship between the type of family system and depression. We also determined the prevalence of depression in the elderly, as well as correlation of depression with other important socio-demographic variables. Methods A cross-sectional study was carried out in the premises of a tertiary care hospital in Karachi, Pakistan. Questionnaire based interviews were conducted among the elderly people visiting the hospital. Depression was assessed using the 15-item Geriatric Depression Scale. Results Four hundred subjects aged 65 and above were interviewed. The age of majority of the subjects ranged from 65 to 74 years. Seventy eight percent of the subjects were male. The prevalence of depression was found to be 19.8%. Multiple logistic regression analysis revealed that the following were significant (p independent predictors of depression: nuclear family system, female sex, being single or divorced/widowed, unemployment and having a low level of education. The elderly living in a nuclear family system were 4.3 times more likely to suffer from depression than those living in a joint family system (AOR = 4.3 [95% CI = 2.4–7.6]. Conclusion The present study found that residing in a nuclear family system is a strong independent predictor of depression in the elderly. The prevalence of depression in the elderly population in our study was moderately high and a cause of concern. The transition in family systems towards nucleation may have a major deleterious effect on the physical and mental health of the elderly.

  3. Contribution to the study of the unresolved resonance range of the neutrons cross sections

    International Nuclear Information System (INIS)

    This document presents the statistical description of neutron cross sections in the unresolved resonance range. The modeling of the total cross section and of the 'shape - elastic' cross section is based on the 'average R-Matrix' formalism. The partial cross sections describing the radiative capture, elastic scattering, inelastic scattering and fission process are calculated using the Hauser-Feshbach formalism with width fluctuation corrections. In the unresolved resonance range, these models depend on the average resonance parameters (neutron strength function Sc, mean level spacing Dc, average partial reaction widths Γc, channel radius ac, effective radius R' and distant level parameter R-barc∞). The codes (NJOY, CALENDF...) dedicated to the processing of nuclear data libraries (JEFF, ENDF/B, JENDL, CENDL, BROND... ) use the average parameters to take into account the self-shielding phenomenon for the simulation of the neutron transport in Monte-Carlo (MCNP, TRIPOLI... ) and deterministic (APOLLO, ERANOS...) codes. The evaluation work consists in establishing a consistent set of average parameters as a function of the total angular momentum J of the system and of the orbital moment of the incident neutron l. The work presented in this paper aims to describe the links between the S-Matrix and the 'average R-Matrix' formalism for the calculation of Sc, R-barc∞, ac and R'. (author)

    Full Text Available The study was designed to determine clinical profile of haemophilia patients in North India. In this cross-sectional study, we obtained family history and clinical profile of 54 diagnosed severe haemophilia patients attending Haemophilia Treatment Centre, Children Hospital LLR Hospital, Kanpur, India, for factor replacement therapy. We also obtained blood samples to investigate for hepatitis B, HIV. In study we observed that majority of the patients having their first presentation in their infancy (70.3% and median age of first presentation was 11 months of age. Though haemophilia is a genetic disorder, family history was negative in majority of patients; (70.3% subcutaneous tissue was most frequent site for initial bleeds, but as age advances joints become frequently involved and hemarthrosis was commonest complication affecting 79.6% patients. Most common involved joint was knee joint (53.7%. This hemarthrosis is the major cause of morbidity affecting quality of life of patients. Due to cost of treatment, many times we have to transfuse blood and blood products which may lead to Transfusion Transmitted Infection (TTI. In our study prevalence of TTI was 1.85% and 3.70% for HIV and Hep. B respectively. We also observed that there was time lag of >1 month in 16.5% cases between onset of symptom and definitive diagnosis, which shows lack of awareness among doctors in community. In view of this high morbidity and TTIs, we emphasize the free availability of factor concentrates and prophylactic treatment should be followed instead of palliative treatment.

    Full Text Available Introduction: Alcohol abuse is one of the health problems that all societies have involved with. Although in Iran the percent of alcohol consuming due to social and cultural preventions is lesser that other countries, its outcome and predictive factors are not accessible. Thus, this study was designed with the aim of determining the consequences of alcohol consuming and finding its effective factors in Tabriz. Method: This cross-sectional study has been done through September 2013 to July 2014 in Sina Hospital, Tabriz, Iran. All individuals with alcohol poisoning referred to the emergency department were included in the study. Demographic and clinical factors of patients, laboratory tests, dialysis and hospitalization in hospital wards were evaluated. Finally, independent effective factors for dialysis and hospitalization were assessed by using multivariate logistic regression. Results: At the end, 81(91.4% male patients with the mean age of 27.9±10.4 years were entered to the study. Ten (12.3% patients needed dialysis and 34 (42.0% were hospitalized. Increasing the serum creatinine level (OR-1.6; 95% Cl: 1.004-2.4; p-0.048 and time interval between consumption until referring to the emergency (OR-1.1; 95% Cl: 1.03-1.15; p-0.004 were the independent predictive factors of dialysis. Also, predictive agents of hospitalization included smoking (OR-3.4; 95% Cl: 1.6-5.5; p-0.01 and need to do dialysis (OR-7.9; 95% Cl: 5.4-10.5; p<0.001. Conclusion: In the present project 12.3% of patients needed dialysis. Increasing the serum creatinine and time interval between alcohol consuming until referring to the emergency were the most important predictive factors. In addition, the probability of hospitalization for smoking and dialyzed poisoned persons in hospital wards was more than other patients.

    Full Text Available Preceding research has linked noise exposure, road traffic bring the dominant community source, with annoyance, which is an indicator of more serious, chronic health conditions. This study aimed to explore the association between residential road traffic noise and self-reported annoyance from an adult Indian population, residing close to roadways. The cross-sectional study used a questionnaire survey in an urban Indian municipality along roadways, where faηade noise assessment was made manually. The survey included randomly selected subjects aged 19-59 years, residing minimum of 10 years in the area and residing within 50 m of the roadways. Association of self-reported annoyance and noise exposure was examined by binary and multiple logistic regressions. The noise exposure was classified in units of 5 dB (A from <65 dB (A to 80 dB (A. Self-reported annoyance was marked at levels above 65-70 dB (A. A 67.5 dB (AA is suggested as a threshold level. The association was statistically significant for female subjects with the adjusted odds ratio being 2.35 (95% confidence intervals: 0.99-5.58. Prevalence of annoyance was more for male subjects. Both age and period of residence were significant predictors of annoyance. Vulnerable age sub-groups were 34-40 years, followed by 50-60 years. The results of this study further suggest the association residential noise exposure near roadways and self-reported annoyance, among the study subjects.

    Epidemiological studies of different dietary patterns and the risk of hypertension among a middle-aged Chinese population remain extremely scare. Thus, the aim of this study was to identify dietary patterns and investigate the relationship between dietary patterns and the risk of hypertension among Chinese adults aged 45–60 years. The present cross-sectional study includes 2560 participants who reported their dietary intake using a validated food frequency questionnaire (FFQ). Dietary patterns were identified using factor analysis. Anthropometric measurements were obtained using standardized procedures. We used log-binomial regression analysis to examine the associations between dietary patterns and hypertension risk. Four major dietary patterns were identified and labeled as traditional Chinese, animal food, western fast-food, and high-salt patterns. After adjusting for potential confounders, participants in the highest quartile of animal food pattern scores had a greater prevalence ratio (PR) for hypertension (PR = 1.26; 95% confidence interval (CI): 1.064–1.727; p < 0.05) in comparison to those from the lowest quartile. Compared with the lowest quartile of high-salt pattern, the highest quartile had a higher prevalence ratio for hypertension (PR = 1.12; 95% CI: 1.013–1.635; p < 0.05). Conclusions: Our findings indicated that animal food and high-salt patterns were associated with increased risk of hypertension, while traditional Chinese and western fast-food patterns were not associated with the risk of hypertension. Further prospective studies are warranted to confirm these findings. PMID:27120612

    ABSTRACT Pyrethroids are a class of insecticides used widely for vector control programs. Acute pyrethroid poisoning is rare, but well documented, whereas effects of cumulative exposure are insufficiently described, including possible negative effect on glucose regulation. The objective of this study was to investigate an association between exposure to pyrethroids and abnormal glucose regulation (prediabetes or diabetes). A cross-sectional study was performed among 116 pesticide sprayers from public vector control programs in Bolivia and 92 nonexposed controls. Pesticide exposure (duration, intensity, cumulative exposure) was assessed from questionnaire data. Participants were asked about symptoms of diabetes. Blood samples were analyzed for glycosylated hemoglobin (HbA1c), a measure of glucose regulation. No association was found between pyrethroid exposure and diabetes symptoms. The prevalence of abnormal glucose regulation (defined as HbA1c ≥ 5.6%) was 61.1% among sprayers and 7.9% among nonexposed controls, corresponding to an adjusted odds ratio (OR [95% confidence interval]) for all sprayers of 11.8 [4.2–33.2] and 18.5 [5.5–62.5] for pyrethroid-exposed only. Among sprayers who had only used pyrethroids, a significant positive trend was observed between cumulative pesticide exposure (total number of hours sprayed) and adjusted OR of abnormal glucose regulation, with OR 14.7 [0.9–235] in the third exposure quintile. The study found a severely increased prevalence of prediabetes among Bolivian pesticide sprayers compared with a control group, but the relevance of the control group is critical. Within the spraying group, an association between cumulative exposure to pyrethroids and abnormal glucose regulation was seen. Further studies are needed to confirm this association. PMID:25275407

    Full Text Available Context: Adolescence is a period of biological, cognitive and social transition of such magnitude and rapidity that it is no surprise to find that it is associated with the onset or exacerbation of a number of health-related problems. It is the level of self-awareness among adolescents, which enables them to see where their thoughts and emotions take them. Aims: The aim of this study was to assess the extent of awareness regarding adolescent changes/problems among school going adolescents. Settings and Design: It was a cross-sectional study and was carried out in Block Beri, District, Jhajjar (Haryana. Materials and Methods: A sample of 320 adolescent students of 9 th -12 th classes (80 from each school were selected from four randomly chosen large Government senior secondary schools with strength of more than 250 students (two girls and two boys/co-ed senior secondary schools. Data were collected on predesigned, pre-tested and semi-structured schedules by conducting in-depth interviews of selected study adolescents by the investigator. Statistical Analysis Used: Percentages, proportions, Chi-square test, Chi-square test with Yate′s correction and t-test. Results: Out of 320, 212 (66.3% study adolescents were aware of at least one adolescent change(s whereas, when probed and further asked to enumerate the changes taking place in them, 272/320 (85% adolescents could narrate at least one such change. Out of those 272, 24 (8.82% (95% CI 6.0-12.79 adolescents either did not consider these changes as normal or they did not know whether the changes were normal or abnormal. Conclusions: Adolescents greatly lack correct information related to their bodies′ physiological, psychological and sexual changes. There is an urgent need for regular adolescent friendly information, education and communication activities covering different aspects of adolescent knowledge needs/problems.

    Full Text Available OBJECTIVE: This study seeks to understand the drivers of overall patient satisfaction in a predominantly low-income, ethnic-minority population of HIV primary care patients. The study's primary aims were to determine 1 the component experiences which contribute to patients' evaluations of their overall satisfaction with care received, and 2 the relative contribution of each component experience in explaining patients' evaluation of overall satisfaction. METHODS: We conducted a cross-sectional study of 489 adult patients receiving HIV primary care at two clinics in Houston, Texas, from January 13-April 21, 2011. The participation rate among eligible patients was 94%. The survey included 15 questions about various components of the care experience, 4 questions about the provider experience and 3 questions about overall care. To ensure that the survey was appropriately tailored to our clinic population and the list of component experiences reflected all aspects of the care experience salient to patients, we conducted in-depth interviews with key providers and clinic staff and pre-tested the survey instrument with patients. RESULTS: Patients' evaluation of their provider correlated the strongest with their overall satisfaction (standardized β = 0.445, p<0.001 and accounted for almost half of the explained variance. Access and availability, like clinic hours and ease of calling the clinic, also correlated with overall satisfaction, but less strongly. Wait time and parking, despite receiving low patient ratings, did not correlate with overall satisfaction. CONCLUSIONS: The patient-provider relationship far exceeds other component experiences of care in its association with overall satisfaction. Our study suggests that interventions to improve overall patient satisfaction should focus on improving patients' evaluation of their provider.

    Full Text Available To determine and describe clinical symptoms, demographic characteristics and environmental exposures as determinants of pulmonary mycobacterial diseases among patients examined for tuberculosis in agropastoral communities in Northern Tanzania.This was a cross sectional study. Sputum samples were collected from patients attending three hospitals in Tanzania, and were investigated for pulmonary tuberculosis by microscopy between November 2010 and June 2012. The patients were interviewed about background information, and potential exposure to mycobacteria.We examined 1,711 presumptive tuberculosis cases where 936 (54.2% were males and 775 (45.3% females. Of all the study participants, 277 (16% were found to have sputum samples positive for mycobacteria; 228 (13% were smear positive, 123 (7% were culture positive and 74 (4% were positive by both smear microscopy and culture. Of the 123 mycobacterial culture positive, 15 (12.2% had non-tuberculous mycobacteria. Males were more likely than females to be positive for mycobacteria. Factors associated with mycobacterial disease were loss of appetite, age groups below 41 years, and being a male. Among HIV negative patients, loss of appetite, age below 20 years and being a male were associated with being mycobacterial positive. Among HIV positive patients, males and those patients with a persistently coughing family member were more likely to harbor mycobacteria.The findings in this study show that both M. tuberculosis and non-tuberculous mycobacterial strains were prevalent in the study community. Some risk factors were identified. Although the reported predictors may improve screening for mycobacterial diseases, their use requires some precaution.

    This study was designed to investigate the current prevalence of hyperhomocysteinemia (Hhcy) and its association with hypertension in rural adults of Northeast China. A cross-sectional study was performed in subjects aged⩾35 years in a general Chinese population. Demographic data, laboratory examination of traditional cardiovascular risk factors and self-reported information on lifestyle factors, such as physical activities, current smoking and drinking status, dietary habits and familial factors were collected by trained personnel. A total of 7130 participants (3317 men and 3813 women) were included in this study and the mean Hhcy level of the whole population was 17.39±12.34 mmol l(-1), which was 20.99±14.83 mmol l(-1) in males and 14.19±8.51 mmol l(-1) in females, respectively. Prevalence of Hhcy in total population was 41.3%. Stratified by gender, the prevalence of Hhcy was higher in males than in females (59.0 vs 25.8%, P<0.05). After adjustment for conventional risk factors including age, salt intake, smoking, body mass index, diabetes, dyslipidemia, activity time and family history, multiple logistic regression analysis showed that Hhcy was independently associated with the risk of hypertension in males (odds ratio (OR)=1.501, 95% confidence interval (CI): 1.012-2.227; P<0.001), but not in females in this population (OR=1.182; 95% CI, 0.993-1.407; P=0.060). In conclusion, a high prevalence of Hhcy in the general adult population of rural northeast China was detected and Hhcy may be a risk factor for hypertension, particularly in males. PMID:26155996

    Full Text Available Abstract Background Chronic obstructive pulmonary disease (COPD is frequent and often coexists with other diseases. The aim of this study was to quantify the prevalence of COPD and related chronic comorbidity among patients aged over 40 years visiting family practices in an area of Madrid. Methods An observational, descriptive, cross-sectional study was conducted in a health area of the Madrid Autonomous Region (Comunidad Autónoma de Madrid. The practice population totalled 198,670 persons attended by 129 Family Physicians (FPs, and the study population was made up of persons over the age of 40 years drawn from this practice population. Patients were deemed to have COPD if this diagnosis appeared on their clinical histories. Prevalence of COPD; prevalence of a further 25 chronic diseases in patients with COPD; and standardised prevalence ratios, were calculated. Results Prevalence of COPD in family medicine was 3.2% (95% CI 3.0–3.3 overall, 5.3% among men and 1.4% among women; 90% of patients presented with comorbidity, with a mean of 4 ± 2.04 chronic diseases per patient, with the most prevalent related diseases being arterial hypertension (52%, disorders of lipid metabolism (34%, obesity (25%, diabetes (20% and arrhythmia (15%. After controlling for age and sex, the observed prevalence of the following ten chronic diseases was higher than expected: heart failure; chronic liver disease; asthma; generalised artherosclerosis; osteoporosis; ischaemic heart disease; thyroid disease; anxiety/depression; arrhythmia; and obesity. Conclusions Patients with COPD, who are frequent in family practice, have a complex profile and pose a clinical and organisational challenge to FPs.

    Hepatitis A virus (HAV) remains a public health concern worldwide contributing to significant morbidity in developed and developing countries. This cross-sectional database study estimated the overall HAV seroprevalence and the seroprevalence by gender, age, region and socioeconomic status in Mexico. Between January and October 2010, serum samples collected during the National Health and Nutrition survey (ENSANUT 2006) were obtained from subjects aged 1–95 y. Subjects’ gender, age, geographical region and socioeconomic status were extracted from the survey and compiled into a subset database by the Mexican National Institute of Public Health. Anti-HAV antibodies were measured using a chemiluminescent immunoassay. A total of 3658 subjects were included in the according-to-protocol cohort. Overall, the HAV seroprevalence was 84.2%. The HAV seroprevalence rates were similar between females (86.1%) and males (82.2%). The percentage of subjects seropositive for anti-HAV antibodies was highest in adults aged ≥ 20 y (96.9%), followed by adolescents aged 10–19 y (80.1%) and lowest in children aged 1–9 y (45.0%) (p < 0.0001). Regionally, the highest HAV seroprevalence rate was observed in the South (88.8%) followed by Central and Northern Mexico and Mexico City (p = 0.02). The HAV seroprevalence was similar between subjects of high socioeconomic (90.1%) status and of low socioeconomic status (86.6%). This study confirms the intermediate HAV endemicity in Mexico. Cost-effectiveness studies are necessary to evaluate the inclusion of an effective hepatitis A vaccine from a population-based perspective in addition to continuous efforts to improve hygiene and sanitation that have a substantial impact on the disease burden.

    Full Text Available Background: Menstruation is a natural phenomenon among matured females who experience shedding of blood for 1-7 days every month from the age of maturity until menopause. Menstrual hygiene and management is an issue that is insufficiently acknowledged and has not received adequate attention.Aims and Objectives: This study seeks to assess hygienic behavior of unmarried females aged 15 to 22 years and factors affecting their behaviors.Study Design: A cross-sectional study was conducted during 2009-10 on 350 students. They were recruited from educational institutions from a major city in South India. Demographic and menstrual history and hygiene questionnaires were used for obtaining required information. Statistical Packages for the Social Sciences (SPSS for Windows version 16 was used. Descriptive statistics, Chi-sq and Fisher’s exact tests were used for analysis.Results: Mean age of menarche was 13.4±1.2 years; disposable pads were used by two-thirds of the selected girls (68.9% regardless of age while 45.1% reported to use both disposable and non disposable materials. Frequency of changing pads was 2-3 times a day by 78.3% girls. Socioeconomic Status (SES of the selected girls and their age influenced choice of napkin/pads and other practices such as storage place of napkins; change during night and during school or college hours and personal hygiene. Older girls had better hygienic practices than the younger ones. Seventy six percent of the participants desired for more information regarding menstruation and hygienic practices.Conclusion: A variety of factors are known to affect menstrual behaviors most influential being age and SES. Awareness regarding the need for information about healthy menstrual practices is on rise among young women. It is probable that a mechanism be introduced to provide knowledge about menstrual health and self maintenance among women.

    Full Text Available Abstract Background Patient safety is vital in patient care. There is a lack of studies on medical errors in primary care settings. The aim of the study is to determine the extent of diagnostic inaccuracies and management errors in public funded primary care clinics. Methods This was a cross-sectional study conducted in twelve public funded primary care clinics in Malaysia. A total of 1753 medical records were randomly selected in 12 primary care clinics in 2007 and were reviewed by trained family physicians for diagnostic, management and documentation errors, potential errors causing serious harm and likelihood of preventability of such errors. Results The majority of patient encounters (81% were with medical assistants. Diagnostic errors were present in 3.6% (95% CI: 2.2, 5.0 of medical records and management errors in 53.2% (95% CI: 46.3, 60.2. For management errors, medication errors were present in 41.1% (95% CI: 35.8, 46.4 of records, investigation errors in 21.7% (95% CI: 16.5, 26.8 and decision making errors in 14.5% (95% CI: 10.8, 18.2. A total of 39.9% (95% CI: 33.1, 46.7 of these errors had the potential to cause serious harm. Problems of documentation including illegible handwriting were found in 98.0% (95% CI: 97.0, 99.1 of records. Nearly all errors (93.5% detected were considered preventable. Conclusions The occurrence of medical errors was high in primary care clinics particularly with documentation and medication errors. Nearly all were preventable. Remedial intervention addressing completeness of documentation and prescriptions are likely to yield reduction of errors.

    Background: Private health care providers are largely the first point of contact for Tuberculosis (TB patients, who either undergo treatment from private practitioners or buy medicines on their own from private pharmacies. Aims: This study assessed the availability, sale and magnitude of anti-tuberculosis drugs dispensing through private pharmacies.

    Methodology: The present cross sectional study was conducted among private pharmacies located along the national highway from Thalassery to Payyannur in the Kannur district of Kerala, India. A total of 38 private pharmacies located along the national highway were included.

    Results: The duration that anti–TB drugs had been on sale showed that 74.3% of pharmacies had started to sell these drugs only less than ten years ago. The majority (82.9% of the private pharmacies received up to 5 prescriptions for anti-TB drugs weekly. Out of the total of 35 pharmacies selling these drugs, 22 (62.9% reported an increase in their sales. Nearly 82% of those pharmacies that reported an increase in the sale of anti-TB drugs were selling these drugs for less than the past ten years.

    Conclusions: The current study shows that a large number of tuberculosis patients are still approaching private pharmacies for anti-tuberculosis drugs. This tendency has to be completely stopped and needs properly planned strategies to encourage private pharmacies to participate actively in the DOTS (Direct Observation Treatment Short course program of the Government, by providing them attractive alternative incentives

    Full Text Available Background: Physical and mental comorbidity is common and has significant implications for overall health outcomes. Psoriasis, a psychocutaneous disorder, is a classic example of mental-physical comorbidity. Aims: In view of the impact of socio-cultural influences on mind-body interactions and the paucity of Indian research pertaining to psychiatric morbidity in psoriatic patients, this study was undertaken to measure the prevalence of anxiety and depression in patients with psoriasis, and to correlate these with severity of psoriasis and quality of life. Materials and Methods: This cross-sectional study was conducted on 90 consecutive patients of psoriasis, over a period of 12 months, in a tertiary care centre. The Psoriasis Area and Severity Index was used to assess severity of psoriasis. PHQ-9, GAD-7 and the Perceived Stress Scale were used to screen for depression, anxiety and perceived stress respectively. The WHOQOL-BREF was used to determine the quality of life. Statistics Analysis: All analysis was performed using Microsoft Excel software and Statistical Package for Social Sciences. Results: A total of 71 (78.9% subjects had depression and 69 (76.7% had anxiety. Fifty one patients had significant stress. A significant positive correlation was established between psoriasis variables (severity and duration of psoriasis and psychological variables (depression, anxiety and stress. Severity of psoriasis had a significant negative correlation with social relationships and environmental domains of WHOQOL. Quality of life was significantly worse in patients with psoriasis with comorbid anxiety/depression. Conclusion: Patients with psoriasis have a clinically significant prevalence of depression, anxiety and perceived stress. This study highlights the complex relationship between psoriasis, psychiatric comorbidity and quality of life and the need to simultaneously consider dermatological and psychological factors.

    Full Text Available Abstract Background Previous research has shown that between 80 and 90 percent of adult smokers report having started smoking before 18 years of age. Several studies have revealed that multiple social factors influence the likelihood of smoking during adolescence, the period during which the onset of smoking usually occurs. To better understand the social mechanisms that influence adolescent smoking, we analyzed the relationship and relative importance of a broad spectrum of social variables in adolescent smoking in Iceland, a Nordic country with high per-capita income. Methods We used cross-sectional data from 7,430 14- to 16 year-old students (approximately 81% of all Icelanders in these age cohorts in the 2006 Youth in Iceland study. The Youth in Iceland studies are designed to investigate the role of several cognitive, behavioral, and social factors in the lives of adolescents, and the data collected are used to inform the design, implementation, and evaluation of substance use prevention programs that are being developed by Icelandic social scientists, policy makers, and practitioners. Results Our analysis revealed that friends' smoking behavior and attitude toward smoking were strongly associated with adolescent smoking and other tobacco use, as well as alcohol consumption during the previous 30 days. Main protective factors were parent's perceived attitude toward smoking, the quantity of time spent with parents, absence of serious verbal conflict between parents and adolescents, and participation in physical activity. Family structure was related to adolescent smoking to a small extent, but other background factors were not. Conclusion We conclude that multiple social factors are related to adolescent smoking. Parents and other primary preventive agents need to be informed about the complicated nature of the adolescent social world in order to maximize their impact.

    Full Text Available Abstract Background Hallux valgus (HV is a very common deformity of the first metatarsophalangeal joint that often requires surgical correction. However, the association between structural HV deformity and related foot pain and disability is unclear. Furthermore, no previous studies have investigated concerns about appearance and difficulty with footwear in a population with HV not seeking surgical correction. The aim of this cross-sectional study was to investigate foot pain, functional limitation, concern about appearance and difficulty with footwear in otherwise healthy adults with HV compared to controls. Methods Thirty volunteers with HV (radiographic HV angle >15 degrees and 30 matched controls were recruited for this study (50 women, 10 men; mean age 44.4 years, range 20 to 76 years. Differences between groups were examined for self-reported foot pain and disability, satisfaction with appearance, footwear difficulty, and pressure-pain threshold at the first metatarsophalangeal joint. Functional measures included balance tests, walking performance, and hallux muscle strength (abduction and plantarflexion. Mean differences (MD and 95% confidence intervals (CI were calculated. Results All self-report measures showed that HV was associated with higher levels of foot pain and disability and significant concerns about appearance and footwear (p Conclusions These findings show that HV negatively impacts on self-reported foot pain and function, and concerns about foot appearance and footwear in otherwise healthy adults. There was also evidence of impaired hallux muscle strength and increased postural sway in HV subjects compared to controls, although general physical functioning and participation in physical activity were not adversely affected.

    2008-07-01

    Full Text Available Abstract Background Despite increasing recognition of the importance of involving patients in decisions on preventive healthcare interventions, little is known about how well patients understand and utilise information provided on the relative benefits from these interventions. The aim of this study was to explore whether lay people can discriminate between preventive interventions when effectiveness is presented in terms of relative risk reduction (RRR, and whether such discrimination is influenced by presentation of baseline risk. Methods The study was a randomised cross-sectional interview survey of a representative sample (n = 1,519 of lay people with mean age 59 (range 40–98 years in Denmark. In addition to demographic information, respondents were asked to consider a hypothetical drug treatment to prevent heart attack. Its effectiveness was randomly presented as RRR of 10, 20, 30, 40, 50 or 60 percent, and half of the respondents were presented with quantitative information on the baseline risk of heart attack. The respondents had also been asked whether they were diagnosed with hypercholesterolemia or had experienced a heart attack. Results In total, 873 (58% of the respondents consented to the hypothetical treatment. While 49% accepted the treatment when RRR = 10%, the acceptance rate was 58–60% for RRR>10. There was no significant difference in acceptance rates across respondents irrespective of whether they had been presented with quantitative information on baseline risk or not. Conclusion In this study, lay people's decisions about therapy were only slightly influenced by the magnitude of the effect when it was presented in terms of RRR. The results may indicate that lay people have difficulties in discriminating between levels of effectiveness when they are presented in terms of RRR.

    Excess sodium consumption is a major cause of high blood pressure and subsequent vascular disease. However, the factors driving people's salt intake behavior remains largely unknown. This study aims to assess the relationship of salt intake behaviors with knowledge and belief on salt and health among older adults in rural China.A cross-sectional survey was conducted among 4693 older participants (men ≥50 and women ≥60 years old) randomly selected from 120 rural villages in 5 northern provinces in China. Healthy salt intake behavior was defined as either not eating pickled foods or not adding pickles/soy sauce/salt when food was not salty enough in prior 3 months.There were 81% participants having healthy salt intake behavior. Healthy salt intake behavior was more common among women (P < 0.01) and was positively associated with age (P < 0.01) and poorer health status (P < 0.01), but negatively associated with years in school (P < 0.05). After adjusting for age, sex, years in school, and health status, participants who believed in the harm of high salt intake were more likely to have healthy salt intake behavior, compared with those who did not believe (Odds Ratio = 1.6, P < 0.001). Knowledge of salt intake was not significantly related to healthy salt intake behavior.Our study demonstrated that belief in the harm of high salt intake rather than knowledge about salt and health was associated with healthy salt intake behavior, independent of age, sex, years in school, and health status. Future population salt reduction programs should place more emphasis on establishing health beliefs rather than only delivering salt-related knowledge.Clinical trial registration number of the study is NCT01259700.

    Full Text Available Abstract Background Only a few studies have investigated non-malignant respiratory effects of glass microfibers and these have provided inconsistent results. Our objective was to assess the effects of exposure to glass microfibers on respiratory and skin symptoms, asthma and lung function. Methods A cross-sectional study of 102 workers from a microfiber factory (response rate 100% and 76 office workers (73% from four factories in Thailand was conducted. They answered a questionnaire on respiratory health, occupational exposures, and lifestyle factors, and performed spirometry. Measurements of respirable dust were available from 2004 and 2005. Results Workers exposed to glass microfibers experienced increased risk of cough (adjusted OR 2.04, wheezing (adjOR 2.20, breathlessness (adjOR 4.46, nasal (adjOR 2.13 and skin symptoms (adjOR 3.89 and ever asthma (adjOR 3.51, the risks of breathlessness (95%CI 1.68–11.86 and skin symptoms (1.70–8.90 remaining statistically significant after adjustment for confounders. There was an exposure-response relation between the risk of breathlessness and skin symptoms and increasing level of microfiber exposure. Workers exposed to sensitizing chemicals, including phenol-formaldehyde resin, experienced increased risk of cough (3.43, 1.20–9.87 and nasal symptoms (3.07, 1.05–9.00. Conclusion This study provides evidence that exposure to glass microfibers increases the risk of respiratory and skin symptoms, and has an exposure-response relation with breathlessness and skin symptoms. Exposure to sensitizing chemicals increased the risk of cough and nasal symptoms. The results suggest that occupational exposure to glass microfibers is related to non-malignant adverse health effects, and that implementing exposure control measures in these industries could protect the health of employees.

  13. Serum vitamin d levels and the components of metabolic syndrome: an analytical cross-sectional study

    International Nuclear Information System (INIS)

    The present study was planned to determine the serum vitamin D levels and its relation with the various components of metabolic syndrome (MetS) in MetS positive and MetS negative subjects. Methods: This analytical cross-sectional study on 88 subjects who were divided into two groups based on whether they fulfill the diagnostic criteria for MetS or not. Fasting serum glucose, lipid profile, insulin, HOMA-IR and vitamin D levels were measured. Two sample-t test and Mann-Whitney U tests were used to compare the differences. Pearson and Spearman correlation tests were used to observe the correlations. Results: BMI (p=0.001), waist/hip ratio (p=0.001), systolic blood pressure (p=0.010), diastolic blood pressure (p=0.010), fasting serum TGs (p = 0.001), TG/HDL ratio (p=0.001), fasting blood sugar (p=0.010), fasting serum insulin (p = 0.001) and HOMA-IR (p=0.001) were significantly high in MetS positive than MetS negative subjects. In MetS Positive subjects, serum vitamin D levels were found to have negative correlation with serum LDL (r= -0.485, p=0.001), total cholesterol (r= -0.408, p=0.007) and total cholesterol/HDL ratio (r= -0.355, p=0.019). Moreover, serum vitamin D levels were found to have positive correlation with HDL/LDL ratio (r= 0.443, p=0.003). Other components of MetS did not show significant correlation with serum vitamin D levels in MetS positive subjects. In MetS negative subjects, serum vitamin D levels did not show any significant correlation with any of the study parameters. Conclusions: Serum vitamin D levels were correlated with a number of MetS components which may be controlled by optimizing vitamin D levels. (author)

    Introduction: Nowadays, hospitals have turned increasingly towards the Internet and develop their own web presence. Hospital Websites could be operating as effective web resources of information and interactive communication mediums to enhance hospital services to the public. Aim: Therefore, the aim of this study was to assess the quality of websites in Tehran’s public hospitals. Material and methods: This cross-sectional analysis involved all public hospitals in Iran’s capital city, Tehran, with a working website or subsites between April and June, 2014 (N=59). The websites were evaluated using three validated instruments: a localized checklist, Google page rank, and the Alexa traffic ranking. The mentioned checklist consisted of 112 items divided into five sections: technical characteristics, hospital information and facilities, medical services, interactive on-line services and external activities. Data were analyzed using descriptive and analytical statistics. Results: The mean website evaluation score was 45.7 out of 224 for selected public hospitals. All the studied websites were in the weak category based on the earned quality scores. There was no statistically significant association between the website evaluation score with Google page rank (P=0.092), Alexa global traffic rank and Alexa traffic rank in Iran (P>0.05). The hospital websites had a lower quality score in the interactive online services and external activities criteria in comparing to other criteria. Due to the low quality level of the studied websites and the importance of hospital portals in providing information and services on the Internet, the authorities should do precise planning for the appreciable improvement in the quality of hospital websites.

    Full Text Available Abstract Background Patients with irritable bowel syndrome (IBS often relate symptoms to the intake of certain foods. This study assesses differences in diet in subjects with and without IBS. Methods The cross-sectional, population-based study was conducted in Norway in 2001. Out of 11078 invited subjects, 4621 completed a survey about abdominal complaints and intake of common food items. IBS and IBS subgroups were classified according to Rome II criteria. Results IBS was diagnosed in 388 subjects (8.4% and, of these, 26.5% had constipation-predominant IBS (C-IBS, 44.8% alternating IBS (A-IBS, and 28.6% diarrhoea-predominant IBS (D-IBS. Low intake of dairy products (portions/day (Odds Ratio 0.85 [CI 0.78 to 0.93], p = 0.001 and high intake of water (100 ml/day (1.08 [1.02 to 1.15], p = 0.002, tea (1.05 [1.01 to 1.10], p = 0.019 and carbonated beverages (1.07 [1.01 to 1.14], p = 0.023 were associated with IBS. A lower intake of dairy products and a higher intake of alcohol and carbonated beverages were associated with D-IBS and a higher intake of water and tea was associated with A-IBS. In subjects with IBS the severity of symptoms was associated with a higher intake of vegetables and potatoes in subjects with C-IBS, with a higher intake of vegetables in subjects with A-IBS, and with a higher intake of fruits and berries, carbonated beverages and alcohol in subjects with D-IBS. Conclusions In this study, the diet differed in subjects with and without IBS and between IBS subgroups and was associated with the severity of symptoms.

    Full Text Available Introduction. Prenatal care is considered an important tool for promoting a healthy lifestyle, but has not been studied as a predictor for maternal weight gain during pregnancy, especially in Romania, where evidence about pregnancy and nutrition is scarce. Objective. This study has aimed to explore the relationship between pre-gestational body mass index (BMI, adequacy of prenatal care and weight gain during pregnancy. Methods. We carried a cross-sectional study on a sample of 400 pregnant women admitted at the “Cuza Voda” Obstetrics and Gynecology Hospital in Iasi. Information regarding demographic characteristics, number of prenatal visits, date of the initial hospital record, nutritional education during pregnancy were registered throughout a questionnaire filled out by means of a direct interview. The anthropometric indicators analyzed were the pre-gestational BMI and the pregnancy weight gain. Data on caloric intake were obtained using a food frequency questionnaire. Results. Weight gain within the limits of the Institute of Medicine recommendations was noticed at 44.35% of the women who declared that they received nutritional advice compared to 40.7% of those who did not receive advice regarding diet during pregnancy. Overweight (53.1% and obese women (66.7% had a larger weight gain than those with a normal pre-pregnancy BMI (29.8% (p<0.001. The variables that were identified with an effect on weight gain in this sample of pregnant women were: inadequate prenatal care, pre-gestational BMI and energy intake. Conclusion. Identifying the pre-gestational BMI and diet changes as predictors of weight gain underline the importance of an individualized prenatal care.

    Fiona Majorin

    Full Text Available BACKGROUND: An estimated 2.5 billion people worldwide lack access to improved sanitation facilities. While large-scale programs in some countries have increased latrine coverage, they sometimes fail to ensure optimal latrine use, including the safe disposal of child feces, a significant source of exposure to fecal pathogens. We undertook a cross-sectional study to explore fecal disposal practices among children in rural Orissa, India in villages where the Government of India's Total Sanitation Campaign had been implemented at least three years prior to the study. METHODS AND FINDINGS: We conducted surveys with heads of 136 households with 145 children under 5 years of age in 20 villages. We describe defecation and feces disposal practices and explore associations between safe disposal and risk factors. Respondents reported that children commonly defecated on the ground, either inside the household (57.5% for pre-ambulatory children or around the compound (55.2% for ambulatory children. Twenty percent of pre-ambulatory children used potties and nappies; the same percentage of ambulatory children defecated in a latrine. While 78.6% of study children came from 106 households with a latrine, less than a quarter (22.8% reported using them for disposal of child feces. Most child feces were deposited with other household waste, both for pre-ambulatory (67.5% and ambulatory (58.1% children. After restricting the analysis to households owning a latrine, the use of a nappy or potty was associated with safe disposal of feces (OR 6.72, 95%CI 1.02-44.38 though due to small sample size the regression could not adjust for confounders. CONCLUSIONS: In the area surveyed, the Total Sanitation Campaign has not led to high levels of safe disposal of child feces. Further research is needed to identify the actual scope of this potential gap in programming, the health risk presented and interventions to minimize any adverse effect.

    Full Text Available Abstract Background Laxatives are efficient drugs, but the effectiveness has been questioned. In nursing homes, the prevalence of constipation is high and laxatives are commonly used drugs. The aims of the study were to assess the effectiveness of laxative therapy in an everyday setting in Norwegian nursing homes, study differences between treatment regimens and factors associated with normal bowel function. Methods A cross-sectional study. After giving informed consent, residents above 60 years of age using laxatives for functional constipation were included, and their characteristics, medical history, use of drugs and bowel functions were recorded. Normal bowel function was defined as bowel movements from 3 times/week to 3 times/day and stool consistency 3-5 on Bristol Stool Form Scale. Results Out of 647 residents in the nursing homes, 197 were included and 116 (59% had normal bowel function. The treatment effect did not differ significantly between the laxatives, treatment regimens or expected efficacy of the regimens. The treatment was unsatisfactorily adapted to individual needs. In subjects with normal bowel function, 113 (97% had persistent complaints; 68 (59.5%, 10 (8.0%, 34 (28.6% and 26 (22.5% reported straining, manual manoeuvre to facilitate bowel movements, feeling of incomplete bowel movements, and feeling of anorectal obstruction respectively. Good nutritional status, previous or present cancer disease and anxiety/depression were predictors of normal bowel function. Conclusions Treatment of constipation in nursing homes was unsatisfactory. Nearly all patients with normal stool frequency and consistence had some persistent complaints. Improved nutrition and individualization of the treatment could improve the outcome.

    Full Text Available Introduction: Prevalence of hearing loss is 11.7% of the school going population (5-15 years. Such children fail to develop speech, language and cognitive skills unless proper habilitation is initiated. If detected early and managed suitably, will have a far better chance at a normal life than those who are habilitated late or not at all. Aims & objectives: To detect the age of suspicion, identification, intervention and treatment seeking behavior of children with hearing loss. Materials & methods: This was a cross- sectional study done in Children between 5 and 15 years age-group with hearing loss, coming to an ENT OPD, New Civil Hospital, Surat during the period of 1st August 2011 to 31 July 2012. Results: A total of 246 children were studied. Mean age of the study population was 9±3.46 years. Average age at first suspicion of hearing loss was 2.9±1.7 years, first consultation was 3.5±1.5 years and first intervention was 7.8±3.3 years. There was significant association between age of first suspicion of congenital hearing loss with father’s occupation (p=0.03. There was significant association between delay in diagnosis and gender (p= 0.04. As the level of education of parents and socio- economic status increased, preference for private set ups for first consultation also increased (p< 0.05. In 63.5% cases, advice of general practitioner resulted in the delay in referral to ENT specialist. Conclusion & Recommendations: Even after primary care, an average gap of 4.3 years is observed among parents for receiving intervention. Mother is the first person to suspect hearing loss among their children. Basic training of general practitioner/ MBBS doctors regarding primary ear care is required.

    Purpose Interdental diameter space is largely undefined in adults, which compromises the decision support for daily interdental cleaning during routine practice in individual oral prophylaxis. This study assesses the distribution of diameter access of interdental spaces in an 18- to 25-year-old adult population free of periodontal disease. Methods In March-April 2015, a cross-sectional study using random sampling was performed at the University Lyon 1, France. The interproximal dental spaces of 99 individuals were examined using a colorimetric calibrated probe associated with the corresponding calibrated interdental brush (IDB). Results Of the 2,408 out of 2,608 sites, the overall accessibility prevalence of any interdental brushing was 92.3%. In total, 80.6% of the sites required interdental brushes with smaller diameters (0.6–0.7 mm). In anterior sites, the diameter of the interdental brushes used was smaller (55.8% of IDB with 0.6 mm) than the diameter of the interdental brushes used in posterior sites (26.1% of IDB with 0.6 mm) (p < 0.01). The adjusted ORs indicate a significant association with the location of the sites (approximately doubling the risk of bleeding, i.e., OR = 1.9, in posterior sites). Conclusions Most interdental sites can be cleaned using interdental brushes. Even in healthy people, interdental hygiene requirements are very high. Strengthening the oral hygiene capacity by specifically using interdental brushes can have an effect on the health of the entire population. Screening of the accessibility of the interdental space should be a component of a routine examination for all patients. PMID:27192409

    Full Text Available Objectives: The African culture seems to play a major prohibiting role in physical exercise during pregnancy and immediate postpartum. This study was designed to assess practice and pattern of antenatal and postnatal exercise among Nigerian women. Materials and Methods: Three hundred and sixty-five women (189 pregnant women and 179 nursing mothers from six selected hospitals in south-west Nigeria participated in this cross-sectional study. Data were obtained on socio-demographic and obstetric characteristics, and practice of antenatal and postnatal exercise. Descriptive and inferential statistics were used to analyze data at P<0.05 alpha level. Results: The mean age of all the respondents was 28.9± 4.63 years. A majority of the pregnant women responders were nulliparous (39.2% while the nursing mother responders were mostly multiparous (54.5%. Prevalence for engagement in physical exercise was 81.9% and mostly based on self-prescription (35.5% and prescription by nurses (28.8%. Antenatal and postnatal exercise practice was 84.7% (160/189 and 79.0% (139/176, respectively. Aerobic (43.5% and stretching (33.4% were the most common type of physical exercises. Exercise frequency was mostly 1-2 times per week (40.8%. There was significant association between exercise practice and education level (χ2=18.795; P=0.001. Conclusion: Engagement in antenatal and postnatal exercise among Nigerian pregnant and nursing women was high and mostly based on self-prescription. Education level significantly influence physical exercise practice among Nigerian women with aerobic and stretching as the predominant exercises in pregnancy and postpartum.

    Background Multiple sclerosis (MS) is a chronic neurological disease that is associated with physical inactivity. Understanding the factors that correlate with physical activity is important for developing effective physical activity promotion programs for this population. Thus, we conducted a cross-sectional study that examined the association between features of the built environment with self-reported and objectively measured physical activity behaviour in adults with MS. Methods Participants with MS (n = 196) were sent a questionnaire packet that included self-report measures of the built environment and physical activity and a pedometer in the mail and were instructed to complete the questionnaires and wear the device for seven days. Participants returned the completed questionnaires in a pre-stamped, pre-addressed envelope. Bivariate correlation analysis was conducted for examining associations between items on the environmental questionnaire with the two measures of physical activity. Stepwise regression analysis was conducted for determining the independent contributions of the significant environmental correlates for explaining variation in physical activity. Results Correlational analysis indicated that presence of shops, stores, markets or other places within walking distance (r = .20; ρ = .18), presence of a transit stop within walking distance (r = .20; ρ = .16), and accessibility of free or low-cost recreation facilities (r = .16; ρ = .15) were related to pedometer, but not self-reported, measured physical activity. Regression analysis indicated that the presence of a transit stop within walking distance independently explained 4% of variance in pedometer measured physical activity. Conclusion Physical activity is an important behaviour to promote among individuals with MS. This study indicated that aspects of the built environment are related to this health promoting behaviour among those with MS. Further research should focus on the longitudinal

    Full Text Available Aims: To study insight correlates in schizophrenia and bipolar mood disorder in remission among out-patients attending the Psychiatry Department of a Tertiary Care Hospital. Settings and Design: In a cross-sectional, naturalistic study, adult patients with schizophrenia and bipolar mood disorder in remission (n = 80; schizophrenia-40, mania-20, bipolar depression-20 were compared on insight measures and clinical correlates. Materials and Methods: Scale to Assess the Unawareness of Mental Disorders (SUMD was used as the main tool to assess current and past measures of insight. Hogan's Drug Attitude Inventory was used to assess the drug attitude and compliance. Positive and Negative Symptom Scale for Schizophrenia, Young's Mania Rating Scale, and HAMD were used to rate psychopathology. Clinical Global Improvement was used as a screening tool for remission. Statistical Analysis: For comparison of the three clinical groups, analysis of variance and Chi-square test were used. In the post-hoc analysis, the Ryan-Einot-Gabriel-Welsch test was used to find the group difference. Results: About 40% in the schizophrenia group were unaware of their mental illness as against none in the bipolar group. The awareness of mental disorder for the current period, the awareness of the achieved effects of medications, and the awareness of social consequence was better in the bipolar group. The drug attitude (compliant positive attitude increased as the SUMD item scale decreased or in other words, as the insight improved. Conclusions: Insight, both current and retrospect, showed significant differences between the schizophrenia and bipolar patients. Insight is significantly correlated with the observed compliance and drug attitude of the patient groups.

    Full Text Available Abstract Background The prevalence of metabolic syndrome has increased over the last few decades in adolescents and has become an important health challenge worldwide. This study analyzed the relationships between metabolic risk factors (MRF and physical activity (PA and physical fitness (PF in a sample of Azorean adolescents. Methods A cross-sectional school-based study was conducted on 417 adolescents (243 girls aged 15-18 from the Azorean Islands, Portugal. Height, weight, waist circumference, fasting glucose, HDL-cholesterol, triglycerides, and blood pressure were measured. A sum of MRF was computed, and adolescents were classified into three groups: no MRF, one MRF and two or more MRF. PA was assessed by a sealed pedometer. PF was assessed using five tests from the Fitnessgram Test Battery. Dietary intake was obtained using a semi-quantitative food frequency questionnaire. Results Mean daily steps for girls and boys were 7427 ± 2725 and 7916 ± 3936, respectively. Fifty-nine percent of the adolescents showed at least one MRF and 57.6% were under the healthy zone in the 20 m Shuttle Run Test. Ordinal logistic regression analysis showed that after adjusting for sex, body mass index, socio-economic status and adherence to a Mediterranean diet, adolescents who were in the highest quartile of the pedometer step/counts (≥9423 steps/day and those who achieved the healthy zone in five tests were less likely to have one or more MRF (OR = 0.56;95%CI:0.33-0.95; OR = 0.55;95%CI:0.31-0.98, respectively. Conclusions Daily step counts and PF levels were negatively associated with having one or more MRF among Azorean adolescents. Our findings emphasize the importance of promoting and increasing regular PA and PF to reduce the public health burden of chronic diseases associated with a sedentary lifestyle.

    Full Text Available Background: Interstitial lung disease (ILD is a type of pulmonary manifestation in patients with rheumatoid arthritis (RA. Mostly RA-ILD has no symptoms and is only diagnosed by clinical examination, pulmonary function test (PFT, and high-resolution computed tomography (HRCT; hence it seems that the diagnosis of pulmonary involvement in early stages of RA is of great importance. Therefore, we decided to answer this question whether the evaluation of RA patients without pulmonary symptoms using methods such as PFT and HRCT are justifiable and reasonable or not. Methods: We conducted a cross-sectional study in a referral rheumatology clinic in Razi hospital of Rasht, Iran. Forty-four consecutive patients, diagnosed with RA, were enrolled. Physical examination of the joints was performed by an rheumatologist. The activity of RA was evaluated in all patients by Disease Activity Score 28. An expert pulmonologist performed the respiratory examination in all participants. Then, all subjects were referred for chest X-ray, PFT, and HRCT of lungs. Results: Patients included in this study, 9 (20.45% males and 35 (79.55% females, were 21–73 years old and their mean age was 49 ± 13 years. Significant relation between PFT and respiratory complaints was observed (P = 0.016. PFT had significant relation with respiratory examinations (P = 0.009. Our results indicated a significant relation between disease activity rate and PFT (P = 0.038. While HRCT had any significant relation with above items. Conclusion: We concluded, using PFT in the respiratory assessment of RA patients can be limited to persons with high disease activity, respiratory complaints, and positive findings in the clinical respiratory examination.

    Full Text Available Aim: To assess the traditional child rearing practices among rural Goan mothers and the various socio demographic factors influencing these practices. Materials and Methods: A cross sectional study was conducted among 307 rural mothers with children < 2 years in two rural areas under rural health and training centre Mandur located 16 kilometres from Panaji Goa, through house to house visits and oral interviews. Analysis of collected data was done using Microsoft Excel and SPSS version. Chi-square test was applied in addition to proportions and percentages. Results: Rooming in was practiced by majority (86% of the mothers within 24 hours of birth. 46.25% of the mothers fed colustrum to their newborns while 73.62 % of the mothers breastfed within 24 hours. 37.59% of the mothers practiced exclusive breastfeeding (EBF for the first six months. The mean duration of breastfeeding was 11.015 th months. 90% of the women was educated 12 standard and above breastfed their babies up to 12 months. Bottle feeding was common (75%. Cereal based diet was the commonest complementary feeding administered by 23% of the mothers. Commonest traditional practices followed included oil massage (97.72% and use of amulets/talisman (97.72% in the study population. Conclusion: Beneficial infant feeding practices such as early initiation of breastfeeding and feeding of colustrum among rural Goan mothers was low despite accessible antenatal care and health care services. However, though some of the traditional children rearing practices followed such as oil massage, delivery at parents' home were as per the recommended norms, some of the beliefs/practices such as kajal application, bathing the newborn immediately after birth, need to be replaced by sound and scientific methods.

    Full Text Available Since Feb, 2013, more than 100 human beings had been infected with novel H7N9 avian influenza virus. As of May 2013, several H7N9 viruses had been found in retail live bird markets (LBMs in Guangdong province of southern China where several human cases were confirmed later. However, the real avian influenza virus infection status especially H7N9 in Guangzhou remains unclear. Therefore, a cross-sectional study of avian influenza in commercial poultry farms, the wholesale LBM and retail LBMs in one district of Guangzhou was conducted from October to November, 2013. A total of 1505 cloacal and environmental samples from 52 commercial poultry farms, 1 wholesale LBM and 18 retail LBMs were collected and detected using real-time RT-PCR for type A, H7, H7N9 and H9 subtype avian influenza virus, respectively. Of all the flocks randomly sampled, 6 farms, 12 vendors of the wholesale LBM and 18 retail LBMs were type A avian influenza virus positive with 0, 3 and 11 positive for H9, respectively. The pooled prevalence and individual prevalence of type A avian influenza virus were 33.9% and 7.9% which for H9 subtype was 7.6% and 1.6%, respectively. None was H7 and H7N9 subtype virus positive. Different prevalence and prevalence ratio were found in different poultry species with partridges having the highest prevalence for both type A and H9 subtype avian influenza virus. Our results suggest that LBM may have a higher risk for sustaining and transmission of avian influenza virus than commercial poultry farms. The present study also indicates that different species may play different roles in the evolution and transmission of avian influenza virus. Therefore, risk-based surveillance and management measures should be conducted in future in this area.

    Full Text Available Background: The poor control of blood pressure is one of the prevalent problems for primary health care services all over the world.Objective: The objective of this study was to evaluate blood pressure control in hypertensive patients. Method: We conducted a cross-sectional study that included 579 subjects representative of the hypertensive patient’s population in Sarvabad city, the west of Iran in 2011. This information was extracted from the family records. Adequate blood pressure control was defined as <140/90 mmHg.Results: The mean age was 65.8 years [95% CI: 64.8, 66.8], 38.7% were male, 9.8% were smokers and 18.3% were obese. Overall, 40% [95% CI: 35.9%, 44.1%] of hypertensive patients had their blood pressure controlled; the age-specific blood pressure control rate was 61.5%, 46.4% and 35.3% in men and 45.2%, 34% and 38.2% in women age 28 to 50 years, 51 to 70 years and above 71 years, respectively.After adjustment the likelihood of having poor control was 0.36 times greater among the diabetic patients, 0.52 times greater among the patients who had a BMI ≥ 30 that these were significant.Conclusion: In all, BP control rate was low (40%.These results suggest that the majority of the treated hypertensive patients are complicated with additional cardiovascular risk factors such as smoking and obesity therefore required a good management of BP control.

    Full Text Available Background: There is a lack of information about the prevalence of stress and types of stressors experienced by Emergency Department (ED patients. Objective: The present aim is to study the prevalence of stress, types of stressful situations and the relationship with other health issues within the ED population. Materials and Methods: This is a cross-sectional study performed in an ED at a level-1 urban trauma center for four months. An anonymous survey was offered to adult non critically ill patients who were admitted in the ED. They were divided on the basis of gender, age and level of stress and were asked about their demographics, reasons for their ED visit and health issues including stress, tobacco, alcohol and marijuana use, weight concern and health. Chi-square for the categorical variables and unpaired t-tests for continuous variables were conducted. Results: We interviewed 1797 patients, over 66% reported that they felt stressed on at least a weekly basis, and over 45% indicated that they felt stressed more than twice per week. While both young and old were equally stressed, females reported significantly more stress. Family, finances and work are the most frequently cited stressors. Different age groups reported different types of stressors. Overall, those patients reporting being stressed more frequently reported more high risk behaviors including cigarette and marijuana use and health problems including being overweight, being depressed, and having sleeping problems and chronic fatigue. Conclusions: Considering the high frequency of ED patients that report frequent stress and high risk behaviors, their ED visit may be an excellent opportunity to provide a referral or an intervention for stress reduction.

    Background: Metabolic syndrome (MS) is a cluster of metabolic disturbances, and its prevalence is increasing worldwide. MS exhibits variations among ethnic groups. Zoroastrianism is an ethnic minority which has maintained its isolation and endogamy up to now. So, we evaluated the frequency of MS in Zoroastrians of Yazd, Iran. Methods: In this cross-sectional study, participants aged ≥30 years were selected using a systematic random sampling. Weight, height, body mass index (BMI), waist circumference (WC), hip circumference (HC), waistto- hip ratio (WHR) and blood pressure (BP) were measured using standard methods. Also, blood levels of glucose, triglycerides (TG), total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), urea, creatinine and uric acid (UA) were measured. Both revised National Cholesterol Education Program Adult Treatment Panel III (ATPIII) and Joint Interim Statement (JIS) criteria were used to diagnose the MS. Results: The mean±SD age of the participants (n=403) was 56.9±12.8 years. The frequency of MS was 69.7% and 74.9% based on JIS and ATPIII criteria, respectively; this was significantly different by age, marital status, job, educational level, and menopausal status (p<0.05). The most prevalent abnormal parameters of MS according to ATPIII and JIS criteria were high WC (95%) and low HDL (87.9%), respectively. Mean LDL, systolic BP, WHR, UA, urea, and creatinine were different between men and women. The difference between the age groups was statistically significant for BMI, systolic BP, diastolic BP, TG, WHR and urea (p<0.05). Conclusion: This study showed a high frequency of MS in Zoroastrians of Yazd, Iran. PMID:27493914

    The correlation between vision and cognition is not fully understood. Visual impairment in the elderly has been associated with impaired cognitive function, dementia, and Alzheimer disease. The aim was to study the correlation between near visual acuity (VA), refraction, and cognitive state in an elderly population.Subjects ≥75 years were enrolled in this cross-sectional study. Refraction and near VA was tested. Cognitive function was evaluated with a version of the mini-mental state examination for the visually impaired (MMSE-blind). The eye with better VA and no cataract or refractive surgery was analyzed.One-hundred ninety subjects (81.6 ± 5.1 years, 69.5% female) were included. Good VA (≤J3) was associated with high MMSE-blind (>17) (OR = 3.18, 95% CI = 1.57-6.43, P = 0.001). This remained significant adjusting for sex, age, and years of education. Wearing reading glasses correlated significantly with high MMSE-blind after adjustment for sex and age (OR = 2.14, 95% CI = 1.16-3.97, P = 0.016), but reached borderline significance after adjustment for education. There was a trend toward correlation between myopia and better MMSE-blind (r = -0.123, P = 0.09, Pearson correlation).Good VA and wearing glasses seem to correlate with better cognitive function. Reading glasses can serve as a protective factor against cognitive deterioration associated with sensory (visual) deprivation in old age. The association between myopia and cognition requires further investigation. PMID:26817872

    The objective was to determine the nasal carriage prevalence of methicillin-resistant Staphylococcus aureus (MRSA) among emergency medical service (EMS) personnel and the associated risk factors. A cross-sectional study was conducted among Ohio EMS personnel randomly sampled from 84 urban and rural agencies. Surveys assessing demographics, occupational history, health, cohabitation status, and hygiene practice were collected with nasal swabs from those who enrolled. Survey weight adjusted analysis was performed (1) to estimate MRSA nasal carriage prevalence of Ohio EMS providers, and (2) to identify variables associated with MRSA. MRSA was detected in 4.6% (13/280) EMS personnel sampled. After employing a survey-weighted analysis the following risk factors associated with MRSA carriage were identified: those who did not practice frequent hand hygiene after glove use (OR, 10.51; 95% CI, 2.54-43.45; P = 0.0012), living with someone with a recent staphylococcal infection (OR, 9.02; 95% CI, 1.03-78.98; P = 0.0470), and individuals with low frequency of hand washing (< 8 times per shift) (OR, 4.20; 95% CI 1.02-17.27; P = 0.0468). An additional risk factor identified through the logistic regression analysis on the study population was EMS workers with an open wound or skin infection (OR, 6.75; 95% CI, 1.25-36.36; P = 0.0262). However, this was not significant in the survey-weighted analysis. The high prevalence of MRSA in Ohio EMS personnel is both an occupational hazard and patient safety concern. Implementing methods to reinforce CDC guidelines for proper hygiene could decrease MRSA found in the EMS setting. Previous literature suggests that a reduction in MRSA colonization can lead to decreases in transmission and improved health for both patients and personnel. PMID:26516797

    Full Text Available Abstract Background To assess the incidence of high-risk population of medical students with eating disorders in Karachi by using validated self-administered questionnaires. The earlier these disorders are diagnosed and assessed, the better the chances are for enhanced treatment and fuller recovery. Therefore, we intended to undertake a study to find out the frequency of such disorders among medical students of Karachi and design strategies to overcome them. Findings A descriptive cross sectional study was conducted in 435 medical students of Karachi. Data was collected using 2 self administered questionnaires, the SCOFF Eating Disorders Questionnaire and the Eating Attitudes Test (EAT-26. Subjects' body mass indexes (BMI were also calculated. The data was sorted and analyzed in SPSS version 16. According to EAT-26, 22.75% individuals were found to be at high-risk of eating disorders, with 87.9% females and 12.1% males. However, according to SCOFF questionnaire, 17% individuals were found to be at high-risk, with 78.4% females and 21.6% males. According to BMI calculation, 9% were severely underweight, 41.4% underweight, 41.1% normal, 7.6% overweight and 0.9% belonged to obese class 1. Conclusions A significant fraction of medical students in Karachi are at high risk of development of eating disorders, females being more prone than males. Strategies should be designed to prevent occurrence of such disorders among medical students that would undoubtedly hamper the availability of dependable medical services in future.

    Full Text Available BACKGROUND/AIMS: Large-scale population studies measuring rates and dynamics of cognitive decline in multiple sclerosis (MS are lacking. In the current cross-sectional study we evaluated the patterns of cognitive impairment in MS patients with disease duration of up to 30 years. METHODS: 1,500 patients with MS were assessed by a computerized cognitive battery measuring verbal and non-verbal memory, executive function, visual spatial perception, verbal function, attention, information processing speed and motor skills. Cognitive impairment was defined as below one standard deviation (SD and severe cognitive impairment as below 2SD for age and education matched healthy population norms. RESULTS: Cognitive performance in our cohort was poorer than healthy population norms. The most frequently impaired domains were information processing speed and executive function. MS patients with secondary-progressive disease course performed poorly compared with clinically isolated syndrome, relapsing-remitting and primary progressive MS patients. By the fifth year from disease onset, 20.9% of patients performed below the 1SD cutoff for impairment, p=0.005, and 6.0% performed below the 2SD cutoff for severe cognitive impairment, p=0.002. By 10 years from onset 29.3% and 9.0% of patients performed below the 1SD and 2SD cutoffs, respectively, p=0.0001. Regression modeling suggested that cognitive impairment may precede MS onset by 1.2 years. CONCLUSIONS: The rates of cognitive impairment in this large sample of MS patients were lower than previously reported and severe cognitive impairment was evident only in a relatively small group of patients. Cognitive impairment differed significantly from expected normal distribution only at five years from onset, suggesting the existence of a therapeutic window during which patients may benefit from interventions to maintain cognitive health.

    Full Text Available Abstract Background Overweight and obesity are considered a serious health problem. There are little data on the prevalence of overweight and obesity among the Yi ethnic group in China. This study aimed to investigate the epidemiologic features of overweight/obesity among Chinese Yi nationality. Methods A cross-sectional study, including 1255 subjects aged 20-75 years, was carried out in Liangshan Yi Autonomous Prefecture of Sichuan province from 2007 to 2008. Overweight/overall obesity was defined by World Health Organization (WHO or the Working Group on Obesity in China. Results Overall, the prevalence of overweight and obesity was 19.0% and 2.9%, respectively, based on the WHO definition, while it was 21.0% and 7.4%, respectively, according to the Working Group on Obesity in China, which is similar to data reported in the 2002 Chinese National Nutrition and Health Survey. Urban residents had a significantly higher prevalence of obesity (WHO criteria: 4.3% vs 1.7% p = 0.008; China criteria: 11.4% vs 3.7%, p p p Conclusions The prevalence of overweight/obesity in the Yi nationality is similar to that in Chinese adults 5 years ago. However, urban residents have a much higher prevalence of overweight/obesity than their rural counterparts. Lifestyle and diet patterns associated with socioeconomic status may explain the difference between urban and rural residents. The prevention of overweight/obesity among urban inhabitants deserves more attention in national health education programs.

    Full Text Available Abstract Background Antihypertensive medications are widely prescribed by doctors and heavily promoted by the pharmaceutical industry. Despite strong evidence of the effectiveness and cost-effectiveness of thiazide diuretics, trends in both promotion and prescription of antihypertensive drugs favour newer, less cost-effective agents. Observational evidence shows correlations between exposure to pharmaceutical promotion and less ideal prescribing. Our study therefore aimed to determine whether print advertisements for antihypertensive medications promote quality prescribing in hypertension. Methods We performed a cross-sectional study of 113 advertisements for antihypertensive drugs from 4 general practice-oriented Australian medical publications in 2004. Advertisements were evaluated using a quality checklist based on a review of hypertension management guidelines. Main outcome measures included: frequency with which antihypertensive classes were advertised, promotion of thiazide class drugs as first line agents, use of statistical claims in advertisements, mention of harms and prices in the advertisements, promotion of assessment and treatment of cardiovascular risk, promotion of lifestyle modification, and targeting of particular patient subgroups. Results Thiazides were the most frequently advertised drug class (48.7% of advertisements, but were largely promoted in combination preparations. The only thiazide advertised as a single agent was the most expensive, indapamide. No advertisement specifically promoted any thiazide as a better first-line drug. Statistics in the advertisements tended to be expressed in relative rather than absolute terms. Drug costs were often reported, but without cost comparisons between drugs. Adverse effects were usually reported but largely confined to the advertisements' small print. Other than mentioning drug interactions with alcohol and salt, no advertisements promoted lifestyle modification. Few

    Full Text Available Abstract Background Childhood tuberculosis (TB has been neglected in the fight against TB. Despite implementation of Directly Observed Treatment Shortcourse (DOTS program in public and private hospitals in Indonesia since 2000, the burden of childhood TB in hospitals was largely unknown. The goals of this study were to document the caseload and types of childhood TB in the 0-4 and 5-14 year age groups diagnosed in DOTS hospitals on Java Island, Indonesia. Methods Cross-sectional study of TB cases recorded in inpatient and outpatient registers of 32 hospitals. Cases were analyzed by hospital characteristics, age groups, and types of TB. The number of cases reported in the outpatient unit was compared with that recorded in the TB register. Results Of 5,877 TB cases in the inpatient unit and 15,694 in the outpatient unit, 11% (648 and 27% (4,173 respectively were children. Most of the childhood TB cases were under five years old (56% and 53% in the inpatient and outpatient clinics respectively. The proportion of smear positive TB was twice as high in the inpatient compared to the outpatient units (15.6% vs 8.1%. Extra-pulmonary TB accounted for 15% and 6% of TB cases in inpatient and outpatient clinics respectively. Among children recorded in hospitals only 1.6% were reported to the National TB Program. Conclusion In response to the high caseload and gross under-reporting of childhood TB cases, the National TB Program should give higher priority for childhood TB case management in designated DOTS hospitals. In addition, an international guidance on childhood TB recording and reporting and improved diagnostics and standardized classification is required

    Background The Australian Guide to Healthy Eating (AGHE) for pregnancy provides a number of food- and nutrition-related recommendations to assist pregnant women in optimizing their dietary behavior. However, there are limited data demonstrating pregnant women’s knowledge of the AGHE recommendations. This study investigated Australian pregnant women’s knowledge of the AGHE and related dietary recommendations for maintaining a healthy pregnancy. The variations in nutrition knowledge were compared with demographic characteristics. Methods A cross-sectional study assessed eight different nutrition knowledge domains and the demographic characteristics of pregnant women. Four hundred women across Australia completed a multidimensional online survey based on validated and existing measures. Results More than half of the pregnant women surveyed (65%) were not familiar with the AGHE recommendations. The basic recommendations to eat more fruit, vegetables, bread, and cereals but less meat were poorly understood. An in-depth investigation of knowledge of nutrition information revealed misconceptions in a range of areas, including standard serving size, nutrients content of certain foods, energy density of fat, and the importance of key nutrients in pregnancy. Univariate analysis revealed significant demographic variation in nutrition knowledge scores. Multiple regression analysis confirmed the significant independent effects on respondents’ nutrition knowledge score (Planguage, and having a health/nutrition qualification. The model indicated that independent variables explained 33% (adjusted R2) of the variance found between respondents’ knowledge scores. Conclusion Australian pregnant women’s knowledge regarding AGHE for pregnancy and other key dietary recommendations is poor and varies significantly with their demographic profile. The setting of dietary guidelines is not sufficient to ensure improvement in their nutrition knowledge. It is essential that women

    Full Text Available Abstract Background Different water choices affect access to drinking water with different quality. Previous studies suggested social-economic status may affect the choice of domestic drinking water. The aim of this study is to investigate whether recent social economic changes in China affect residents’ drinking water choices. Methods We conducted a cross-sectional survey to investigate residents’ water consumption behaviour in 2011. Gender, age, education, personal income, housing condition, risk perception and personal preference of a certain type of water were selected as potential influential factors. Univariate and backward stepwise logistic regression analyses were performed to analyse the relation between these factors and different drinking water choices. Basic information was compared with that of a historical survey in the same place in 2001. Self-reported drinking-water-related diarrhoea was found correlated with different water choices and water hygiene treatment using chi-square test. Results The percentage of tap water consumption remained relatively stable and a preferred choice, with 58.99% in 2001 and 58.25% in 2011. The percentage of bottled/barrelled water consumption was 36.86% in 2001 and decreased to 25.75% in 2011. That of household filtrated water was 4.15% in 2001 and increased to 16.00% in 2011. Logistic regression model showed strong correlation between one’s health belief and drinking water choices (P P  Conclusions Personal health belief, housing condition, age, personal income, education, taste and if worm ever founded in tap water affected domestic drinking water choices in Shanghai.

    Full Text Available Urban living is associated with unhealthy lifestyles that can increase the risk of cardiometabolic diseases. In sub-Saharan Africa (SSA, where the majority of people live in rural areas, it is still unclear if there is a corresponding increase in unhealthy lifestyles as rural areas adopt urban characteristics. This study examines the distribution of urban characteristics across rural communities in Uganda and their associations with lifestyle risk factors for chronic diseases.Using data collected in 2011, we examined cross-sectional associations between urbanicity and lifestyle risk factors in rural communities in Uganda, with 7,340 participants aged 13 y and above across 25 villages. Urbanicity was defined according to a multi-component scale, and Poisson regression models were used to examine associations between urbanicity and lifestyle risk factors by quartile of urbanicity. Despite all of the villages not having paved roads and running water, there was marked variation in levels of urbanicity across the villages, largely attributable to differences in economic activity, civil infrastructure, and availability of educational and healthcare services. In regression models, after adjustment for clustering and potential confounders including socioeconomic status, increasing urbanicity was associated with an increase in lifestyle risk factors such as physical inactivity (risk ratio [RR]: 1.19; 95% CI: 1.14, 1.24, low fruit and vegetable consumption (RR: 1.17; 95% CI: 1.10, 1.23, and high body mass index (RR: 1.48; 95% CI: 1.24, 1.77.This study indicates that even across rural communities in SSA, increasing urbanicity is associated with a higher prevalence of lifestyle risk factors for cardiometabolic diseases. This finding highlights the need to consider the health impact of urbanization in rural areas across SSA. Please see later in the article for the Editors' Summary.

    Full Text Available Objective: To evaluate and describe the sleep quality in seven subscales among the patients with mild traumatic brain injury (TBI and compare it with normal patterns. Methods: This cross-sectional study was conducted within a 6-month period from February to August 2014 in Shahid Rajaei trauma center of Shiraz. Participants were selected randomly from all adult (18-60 years of age patients admitted during the study period with impression of mild TBI (GCS of more than 13. The patients’ sleep quality and demographic characteristics were evaluated by Pittsburgh sleep quality index (PSQI and self- report questionnaire, respectively. Results were compared with normal data, which extracted from the normative data of PSQI manual. Results: Overall we included 60 patients with mild TBI with mean age of 36.2±13.4 years. All the patients had sleep disturbance. Among them there were 46 (76.7% men and 14 (23.3% women. The subjective sleep quality ( p=0.01, sleep latency ( p=0.01, habitual sleep efficiency ( p=0.01, sleep disturbance ( p=0.01, use of sleep medication ( p=0.01 and day time dysfunction ( p=0.01 were significantly impaired in patients with mild TBI when compared to normal values. There were no difference between men and women regarding the sleep quality. The sleep duration was comparable between the subjects and the normal values. Conclusion: Patients with mild TBI have poor sleep quality which should be considered as one of the main factors in interventions after the injury and it might lead to better quality of life.

    This study ascertained the influence of orthodontic appliances on subjective ratings for social competence (SC), intellectual ability (IA), psychological adjustment (PA), and attractiveness in young adult orthodontic patients. A cross-sectional analytical questionnaire study was conducted with 130 undergraduates from the UK. Each participant was asked to look at a single, randomly assigned colour photograph of a young adult female and then asked to make judgements concerning her personal characteristics. Five modified photographs of the same young adult female were used: (1) no appliance, (2) stainless steel fixed orthodontic appliance, (3) ceramic fixed orthodontic appliance, (4) gold fixed orthodontic appliance, and (5) clear colourless aligner. Likert scales with higher scores indicating more positive ratings were used. The results were analysed using chi-square test, one-way univariate analysis of variance, and post hoc Tukey-B and Kruskal-Wallis tests. The results showed that greater perceived IA was associated with the appearance of no appliance (mean values: 7.56) rather than steel (6.67) or ceramic appliances (6.65) but similar to the gold (7.35) and aligner (7.08) appliances. No significant differences between the different orthodontic appliance appearances were found for SC and PA. A trend existed where the no appliance image (resembling a lingual appliance) or clear aligner was considered more attractive than the visible buccal fixed appliances. In the absence of other information, the judgements an individual young adult makes concerning the personal characteristics of a young adult are influenced by dental appearance and orthodontic appliance design. This may influence orthodontic appliance choice. PMID:20651044

    Full Text Available Background: Diarrhea still continues to be a leading cause of childhood morbidity and mortality and holds the second rank (after pneumonia for mortality in children < 5 years of age. The majority of these deaths can be avoided by timely intervention. The knowledge of caretakers about the severity of diarrheal illness ultimately affects the choice for childcare practices and influences the type of therapies received.  Objectives: To assess the various aspect of maternal knowledge about diarrhea in under-five age children. To determine the child care practices of mothers during diarrheal episodes.Materials and methods: A cross-sectional survey was carried out from February to May 2014. 5 villages were selected by systematic random sampling method in rural field training area of medical college. A self-designed and pre-tested structured questionnaire was used as study tool which covers different aspect of knowledge and childcare practices by mothers/caretakers regarding diarrhea. Overall responses of participants were scored as good, average and poor for assessment of knowledge and practice.  Results: Total 972 mother/caretakers were interviewed. Most of the mothers/caretakers (62.1% were in favor of giving of breast milk as preferred oral fluid during diarrheal episode. Nearly one fourth of mothers/caretakers (26.1% identify symptoms and signs of "dehydration" and the need for consultation. During diarrheal episodes less amount of food and fluid was given by 49.9% and 20.4% mothers/caretaker respectively. The higher level educated and employed mothers had better practices (P < 0.001 Conclusion: The study showed that knowledge and childcare practices for diarrhea still remains a great challenge among the rural population. This could be only deals with improvement in female literacy and to develop and implement diarrhea related educational interventions for mothers/caretakers.

    Full Text Available Literature about healthcare-associated infection (HCAI in China is scarce. A cross-sectional anonymous survey was conducted on 647 clinicians (199 physicians and 448 nurses from six Shanghai hospitals (grades A-C to investigate their cognizance, knowledge, attitude, self-reported practice, and risks regarding HCAI with emphasis on precautions. The mean overall score of HCAI knowledge was 40.89±11.4 (mean±SD; range, 13∼72 out of 100 for physicians and 43.48±9.9 (10∼70 for nurses. The respondents generally received high scores in hand hygiene, HCAI core concept, and healthcare worker safety but low scores in HCAI pathogen identification and isolation precautions. There were substantial variations in the knowledge scores of various demographic groups across individual hospitals and within hospital grades (ps<0.05. Within-hospital comparisons showed that the nurses were better than physicians particularly in hand hygiene knowledge in 4 hospitals (ps<0.05. Multiple linear regression analysis showed that longer work experience was inversely and independently associated with the overall and categorical knowledge of nurses, whereas independent associations between older age or higher education and categorical knowledge were noted for physicians. The respondents' self-reported practices and adherence to standard precautions were less than satisfactory. This multi-center study reports a high level of cognizance, patchy knowledge, suboptimal adherence to infection control precautions, and self-protective attitudes among the practicing clinicians regarding HCAI, with potential safety risk to patients and healthcare providers. Providing quality learning resources, enforcing knowledge-informed practice, and promoting a healthcare safety culture are recommended as interventions. Future studies are warranted for social and behavioral aspects of healthcare safety with emphasis on infection control.

    Since Feb, 2013, more than 100 human beings had been infected with novel H7N9 avian influenza virus. As of May 2013, several H7N9 viruses had been found in retail live bird markets (LBMs) in Guangdong province of southern China where several human cases were confirmed later. However, the real avian influenza virus infection status especially H7N9 in Guangzhou remains unclear. Therefore, a cross-sectional study of avian influenza in commercial poultry farms, the wholesale LBM and retail LBMs in one district of Guangzhou was conducted from October to November, 2013. A total of 1505 cloacal and environmental samples from 52 commercial poultry farms, 1 wholesale LBM and 18 retail LBMs were collected and detected using real-time RT-PCR for type A, H7, H7N9 and H9 subtype avian influenza virus, respectively. Of all the flocks randomly sampled, 6 farms, 12 vendors of the wholesale LBM and 18 retail LBMs were type A avian influenza virus positive with 0, 3 and 11 positive for H9, respectively. The pooled prevalence and individual prevalence of type A avian influenza virus were 33.9% and 7.9% which for H9 subtype was 7.6% and 1.6%, respectively. None was H7 and H7N9 subtype virus positive. Different prevalence and prevalence ratio were found in different poultry species with partridges having the highest prevalence for both type A and H9 subtype avian influenza virus. Our results suggest that LBM may have a higher risk for sustaining and transmission of avian influenza virus than commercial poultry farms. The present study also indicates that different species may play different roles in the evolution and transmission of avian influenza virus. Therefore, risk-based surveillance and management measures should be conducted in future in this area. PMID:25356738

    Introduction Burnout is a job-related stress reaction; a potential hazard for personal, professional lives of dentists. Work Engagement (WE) is the antithesis of Burnout and they can co-exist. Aim This study was taken up to know the prevalence of Burnout and WE among dentists in Bangalore, India. Matreials and Methods In a cross-sectional study, all (n=116) dentists practicing in Bangalore East Zone were randomly selected. A structured, self-administered questionnaire revealing dentists’ demographics, practice characteristics, Burnout level [6-item from Maslach Burnout Inventory] and WE [4-item from Utrecht Work Engagement Scale] was used. Ethical clearance and informed consent was obtained. The data was analyzed using SPSS version 15.0. Results With a response rate of 58.6%, high burnout was seen in 5.15% dentists. Personal Accomplishment was significantly associated with dentists in older age-group (p=0.002), married (p=0.014), MDS qualified (p=0.038), having long working hours (p=0.009) with assistants (p=0.024), more years into practice (0.007), travelling more distance from residence (p=0.021). Significance was also seen for dedication among dentists with assistants (p=0.006), emotional exhaustion among dentist with long working hours (p=0.009), and driving own vehicle (p=0.028). Finally absorption was found significant in dentists practicing solo. Conclusion Higher WE were found but still burnout persisted. Thus, burnout and WE were found to co-exist. PMID:27042589

    Full Text Available Background: Recently, certain long chain polyunsaturated fatty acids (LCPUFA have been shown to exert functional benefits with regards to gestational length. The present study examined the association of maternal LCPUFA intake, specifically Docosahexaenoic acid(DHA and Arachidonic acid (ARA, and plasma status at delivery with duration of gestation and risk of premature delivery in Indian mothers.Methods: In a cross-sectional nested case-control study, 191 mother-baby pairs [164 Full term(FT and 27 Preterm (PT] were examined for differences in maternal habitual diet pattern and plasma fatty acid composition in relation to the length of gestation.Results: The frequency of intake of n-3 fatty acid rich varieties of fish was higher (p<0.05 in FT mothers compared to PT mothers. Maternal plasma fatty acid concentration of n-3 Alpha Linolenic acid (ALA, Eicosapentaenoic acid (EPA, DHA and total n-3 fatty acids at delivery was significantly associated with intake of vegetarian ALA sources such as millets, dark whole pulses, dry fruits like walnuts, and green leafy vegetables. Among age, parity, and neonatal sex matched case-control pairs, PT mothers had significantly (p<0.01 higher levels of n-6 ARA, but lower (p<0.01 levels of n-3 DHA and total n-3 fatty acids compared to FT mothers irrespective of socioeconomic group. In fact, mothers with plasma DHA levels below median (<3.0% had ten times higher risk (OR-10.47; 95% CI: 3.03-36.48 of delivering prematurely compared to those who had plasma DHA levels above median.Conclusion: Results underscore the importance of consuming varied sources of ALA and DHAfor their role as functional lipids in determining gestational length.

    Full Text Available Abstract Background Epidemiological data indicate elevated psychosocial health risks for physicians, e. g., burnout, depression, marital disturbances, alcohol and substance abuse, and suicide. The purpose of this study was to identify psychosocial health resources and risk factors in profession-related behaviour and experience patterns of medical students and physicians that may serve as a basis for appropriate health promoting interventions. Methods The questionnaire -Related Behaviour and Experience "Work administered in cross-sectional surveys to students in the first (n = 475 and in the fifth year of studies (n = 355 in required courses at three German universities and to physicians in early professional life in the vicinity of these universities (n = 381. Results Scores reflecting a healthy behaviour pattern were less likely in physicians (16.7% compared to 5th year (26.0% and 1st year students (35.1% while scores representing unambitious and resigned patterns were more common among physicians (43.4% vs. 24.4% vs. 41.0% and 27.3% vs. 17.2% vs. 23.3 respectively. Female and male responders differed in the domains professional commitment, resistance to stress and emotional well-being. Female physicians on average scored higher in the dimensions resignation tendencies, satisfaction with life and experience of social support, and lower in career ambition. Conclusion The results show distinct psychosocial stress patterns among medical students and physicians. Health promotion and prevention of psychosocial symptoms and impairments should be integrated as a required part of the medical curriculum and be considered an important issue during the further training of physicians.

    Background:Many studies have reported that depression and anxiety have bidirectional relationship with headache.However,few researches investigated the roles of depression or anxiety in patients with headache.We surveyed the prevalence of depression and anxiety as a complication or cause of headache among outpatients with a chief complaint of headache at neurology clinics in general hospitals.Additional risk factors for depression and anxiety were also analyzed.Methods:A cross-sectional study was conducted at 11 general neurological clinics.All consecutive patients with a chief complaint of headache were enrolled.Diagnoses of depression and anxiety were made using the Chinese version of the Mini International Neuropsychiatric Interview,and those for headache were made according to the International Classification of Headache Disorders,2nd Edition.The headache impact test and an 11-point verbal rating scale were applied to assess headache severity and intensity.Logistic regression was used to analyze risk factors of patients with headache for depression or anxiety.Results:A total of 749 outpatients with headache were included.Among them,148 (19.7%) were diagnosed with depression and 103 (13.7%) with anxiety.Further analysis showed that 114 (15.2%) patients complaining headache due to somatic symptoms of psychiatric disorders and 82 (10.9%) had a depression or anxiety comorbidity with headache.Most patients with depression or anxiety manifested mild to moderate headaches.Poor sleep and severe headache-related disabilities were predictors for either depression or anxiety.Conclusion:Clinicians must identify the etiology of headache and recognize the effects of depression or anxiety on headache to develop specific treatments.

  13. Consanguinity and major genetic disorders in Saudi children: Acommunity-based cross-sectional study

    International Nuclear Information System (INIS)

    There is a high rate of consanguinity in Saudi Arabia; however,information on its relationship with genetic disorders is limited. Theobjective of this cross-sectional study was to explore the role ofconsanguinity in genetic disorders. The study sample was determined by amultistage probability random sampling procedure. Primary care physiciansperformed a history and physical examination of all children and adolescentsyounger than 19 years and all cases of genetic diseases were recorded. Thechi-square test was used to compare proportions. During the two-year studyperiod (2004-2005), 11554 of 11874 (97%) mothers answered the question onconsanguinity and 6470 of 11554 (56%) were consanguineous. There was nosignificant association between first-cousin consanguinity and Down syndrome(P=0.55). Similarly, there was no significant association with either sicklecell disease (P=0.97) or glucose-6-phosphate dehydrogenase deficiency(P=0.67) for-cousin in consanguinity. A borderline statistical significancewas found for major congenital malformations (P=0.05). However, the mostsignificant association with first-cousin consanguinity was congenital heartdisease (CHD) (P=0.01). Finally, no significant association was found fortype 1 diabetes mellitus (P=0.92). For all types of consanguinity, similartrends of association were found, with a definite statistically significantassociation only with CHD (P=0.003). The data suggest a significant role ofparental consanguinity in CHD. However, a relationship between consanguinityand other genetic diseases could not be established. The effect ofconsanguinity on genetic diseases is not uniform and this should be takeninto consideration in genetic counseling. (author)

    Full Text Available OBJECTIVES: Offspring of older men have impaired cognitive ability as children, but it is unclear if this impairment persists into adulthood. The main objective of this study was to explore the association between paternal age at offspring birth and general cognitive ability as young adults. DESIGN: Population-based cross-sectional study with prospectively collected data on obstetric factors and parental education. SETTING: Nationwide Danish sample. PARTICIPANTS: Male conscripts (n = 169,009. PRIMARY AND SECONDARY OUTCOME MEASURES: General cognitive ability as assessed by the Børge Priens test score, an intelligence test with components related to logical, verbal, numerical and spatial reasoning. RESULTS: We observed an inverse U-shaped association between paternal age and general cognitive ability (slightly lower test scores in the offspring of fathers aged less than 25 years and older than 40 years, compared with fathers aged 25 to 29 years. However, after adjustment for maternal age, parental education and birth order the shape of the association changed. Offspring of fathers younger than 20 still showed slightly lower cognitive ability (-1.11 (95% CI -1.68 to -0.54, but no significant impairments were identified in the men whose fathers were older than 29 years at the time of their birth (e.g. the mean difference in test score in the offspring of fathers aged 40 to 44 years were -0.03 [95% CI (-0.27 to 0.20] compared with fathers aged 25 to 29 years. CONCLUSIONS: We did not find that the offspring of older fathers had impaired cognitive ability as young adults. Whereas, we found a tendency that the offspring of teen fathers have lower cognitive ability. Thus, our results suggest that any potentially deleterious effects of older fathers on general cognitive ability as young adults may be counter-balanced by other potentially beneficial factors.

    Full Text Available Abstract Background Moderate alcohol consumption is protective against coronary artery disease. Endothelial dysfunction contributes to atherosclerosis and the pathogenesis of cardiovascular disease. The effects of alcohol consumption on endothelial function may be relevant to these cardiovascular outcomes, but very few studies have examined the effect of alcohol consumption on endothelial function assessed by flow-mediated dilation (FMD of the brachial artery in humans. Methods In the population-based Northern Manhattan Study (NOMAS, we performed a cross-sectional analysis of lifetime alcohol intake and brachial artery FMD during reactive hyperemia using high-resolution B-mode ultrasound images among 884 stroke-free participants (mean age 66.8 years, women 56.6%, Hispanic 67.4%, black 17.4%, and white 15.2%. Results The mean brachial FMD was 5.7% and the median was 5.5%. Compared to non-drinkers, those who drank >1 drink/month to 2 drinks/day were more likely to have FMD above the median FMD (5.5% (unadjusted OR 1.7, 95% CI 1.2–2.4, p = 0.005. In multivariate analysis, the relationship between moderate alcohol consumption and FMD remained significant after adjusting for multiple traditional cardiovascular risk factors, including sex, race-ethnicity, body mass index, diabetes mellitus, coronary artery disease, Framingham risk score, medication use (adjusted OR 1.8, 95%CI 1.1–3.0, p = 0.03. No beneficial effect on FMD was seen for those who drank more than 2 drinks/day. Conclusion In conclusion, consumption of up to 2 alcoholic beverages per day was independently associated with better FMD compared to no alcohol consumption in this multiethnic population. This effect on FMD may represent an important mechanism in explaining the protective effect of alcohol intake on cardiovascular disease.

    Full Text Available Abstract Background Primary care plays a key role in the prevention and management of cardiovascular disease (CVD. We examined primary care practice adherence to recommended care guidelines associated with the prevention and management of CVD for high risk patients. Methods We conducted a secondary analysis of cross-sectional baseline data collected from 84 primary care practices participating in a large quality improvement initiative in Eastern Ontario from 2008 to 2010. We collected medical chart data from 4,931 patients who either had, or were at high risk of developing CVD to study adherence rates to recommended guidelines for CVD care and to examine the proportion of patients at target for clinical markers such as blood pressure, lipid levels and hemoglobin A1c. Results Adherence to preventive care recommendations was poor. Less than 10% of high risk patients received a waistline measurement, half of the smokers received cessation advice, and 7.7% were referred to a smoking cessation program. Gaps in care exist for diabetes and kidney disease as 54.9% of patients with diabetes received recommended hemoglobin-A1c screenings, and only 55.8% received an albumin excretion test. Adherence rates to recommended guidelines for coronary artery disease, hypertension, and dyslipidemia were high (>75%; however Conclusions There remain significant opportunities for primary care providers to engage high risk patients in prevention activities such as weight management and smoking cessation. Despite high adherence rates for hypertension, dyslipidemia, and coronary artery disease, a significant proportion of patients failed to meet treatment targets, highlighting the complexity of caring for people with multiple chronic conditions.

    Full Text Available Background: Pityriasis versicolor (PV is a mild but recurrent superficial fungal infection of stratum corneum. Many predisposing factors such as late teen and young adulthood age, tropical and subtropical climate (and to a lesser extent temperate climate, immunosuppression, malnutrition, use of oral contraceptives, hyperhidrosis, poor hygiene and a few other factors have been proposed for this condition. Aim: Regarding these probable and possible risk factors, we felt that jail is a unique population which can be affected by this infection and therefore we decided to evaluate some aspects of this infection in this population. Methods: In this cross-sectional study in male prisoners of Bandarabbas city, 230 prisoners were randomly selected. One hundred and five (45.67% of them were diagnosed to be infected. They were also evaluated regarding age, duration of being imprisoned, skin color, site of lesion and its pigmentation change and any concomitant clinical manifestation such as pruritis, burning or cebure. Chi-square test or Fisher′s exact test was used for data analysis. Results: Mean age of infected population was 31.62 ± 8.67 years while peak incidence of PV was in 28-32 years age group. The most common color change was hypopigmentation. No case of PV hyperpigmentation was seen. We could not also observe any association between skin color and duration of being imprisoned with the frequency of infection. Conclusion: There seems to be no difference between pattern of infection in the general population and prisoners′ population in the aspects evaluated.

    In 1998 a cross-sectional study of violence against women was undertaken in three provinces of South Africa. The objectives were to measure the prevalence of physical, sexual and emotional abuse of women, to identify risk factors and associated health problems and health service use. A multi-stage sampling design was used with clusters sampled with probability proportional to number of households and households were randomly selected from within clusters. One randomly selected woman aged 18-49 years was interviewed in each selected home. Interviews were held with a total 1306 women, the response rate was 90.3% of eligible women. For the risk factor analysis, multiple logistic regression models were fitted from a large pool of candidate explanatory variables, while allowing for sampling design and interviewer effects. The lifetime prevalence of experiencing physical violence from a current or ex-husband or boyfriend was 24.6%, and 9.5% had been assaulted in the previous year. Domestic violence was significantly positively associated with violence in her childhood, her having no further education, liberal ideas on women's roles, drinking alcohol, having another partner in the year, having a confidant(e), his boy child preference, conflict over his drinking, either partner financially supporting the home, frequent conflict generally, and living outside the Northern Province. No significant associations were found with partners' ages, employment, migrant status, financial disparity, cohabitation, household possessions, urbanisation, marital status, crowding, communication, his having other partners, his education, her attitudes towards violence or her perceptions of cultural norms on women's role. The findings suggest that domestic violence is most strongly related to the status of women in a society and to the normative use of violence in conflict situations or as part of the exercise of power. We conclude by discussing implications for developing theory on causal

    Frailty is a common syndrome among elderly and sensory decline may exacerbate functional decline. The hand function, the manual dexterity, the performance of the daily living skills and the social interactions are determined, in a large degree, by sensory integrity. However, hand tactile sensory deterioration has been little explored in frailty. We performed a cross sectional observational study with 181 of institutionalized elders. From the initial sample we selected 50 subjects (68-99 years) who met the inclusion/exclusion criteria. Our goals were (1) to analyse the relationship between tactile discrimination (TD) of the hand, avoidance behaviours and attitudes towards social touch (BATST) and phenotype frailty criteria (unintentional weight loss, self-perception of exhaustion, decrease grip strength - GS, slow walking speed, low level of physical activity), (2) to explore whether other variables can contribute to explain the differences between pre-frail and frail elders. The results showed that increasing age is related to decline of TD of the hand (p=0.021) and to decrease in GS (p=0.025); women have significantly lower level of GS (p=0.001); TD decrease is correlated with higher avoidance BATST (p=0.000) and with lower GS (p=0.000); Lower GS corresponds to more avoidance BATST (p=0.003). Hand TD also can differentiate frail and pre-frail elderly subjects in this sample (p=0.037). Decreased TD of the hand may have implications on the functionality and on interpersonal relationships. TD of the hand also explains frailty levels in this sample. Hand TD should be used in assessment and intervention protocols in pre-frail and frail elders. PMID:27259030

    Objectives To measure the sex-specific and community-specific mortality rates for adults in Lusaka, Zambia, and to identify potential individual-level, household-level and community-level correlates of premature mortality. We conducted 12 survey rounds of a population-based cross-sectional study between 2004 and 2011, and collected data via a structured interview with a household head. Setting Households in Lusaka District, Zambia, 2004–2011. Participants 43 064 household heads (88% female) who enumerated 123 807 adult household members aged between 15 and 60 years. Primary outcome Premature adult mortality. Results The overall mortality rate was 16.2/1000 person-years for men and 12.3/1000 person-years for women. The conditional probability of dying between age 15 and 60 (45q15) was 0.626 for men and 0.537 for women. The top three causes of death for men and women were infectious in origin (ie, tuberculosis, HIV and malaria). We observed an over twofold variation of mortality rates between communities. The mortality rate was 1.98 times higher (95% CI 1.57 to 2.51) in households where a family member required nursing care, 1.44 times higher (95% CI 1.22 to 1.71) during the cool dry season, and 1.28 times higher (95% CI 1.06 to 1.54) in communities with low-cost housing. Conclusions To meet Zambia's development goals, further investigation is needed into the factors associated with adult mortality. Mortality can potentially be reduced through focus on high-need households and communities, and improved infectious disease prevention and treatment services. PMID:26940113

  1. Workplace determinants of social capital: cross-sectional and longitudinal evidence from a Finnish cohort study.

    Tuula Oksanen

    Full Text Available OBJECTIVE: To examine which contextual features of the workplace are associated with social capital. METHODS: This is a cohort study of 43,167 employees in 3090 Finnish public sector workplaces who responded to a survey of individual workplace social capital in 2000-02 (response rate 68%. We used ecometrics approach to estimate social capital of work units. Features of the workplace were work unit's demographic and employment patterns and size, obtained from employers' administrative records. We used multilevel-multinomial logistic regression models to examine cross-sectionally whether these features were associated with social capital between individuals and work units. Fixed effects models were used for longitudinal analyses in a subsample of 12,108 individuals to examine the effects of changes in workplace characteristics on changes in social capital between 2000 and 2004. RESULTS: After adjustment for individual characteristics, an increase in work unit size reduced the odds of high levels of individual workplace social capital (odds ratio 0.94, 95% confidence interval 0.91-0.98 per 30-person-year increase. A 20% increase in the proportion of manual and male employees reduced the odds of high levels of social capital by 8% and 23%, respectively. A 30% increase in temporary employees and a 20% increase in employee turnover were associated with 11% (95% confidence interval 1.04-1.17 and 24% (95% confidence interval 1.18-1.30 higher odds of having high levels of social capital respectively. Results from fixed effects models within individuals, adjusted for time-varying covariates, and from social capital of the work units yielded consistent results. CONCLUSIONS: These findings suggest that workplace social capital is contextually patterned. Workplace demographic and employment patterns as well as the size of the work unit are important in understanding variations in workplace social capital between individuals and workplaces.

    Full Text Available BACKGROUND: We explore the association between bone T-scores, used in osteoporosis diagnosis, and functional status since we hypothesized that bone health can impact elderly functional status and indirectly independence. METHODS: In a cross-sectional study (2005-2006 on community dwelling elderly (> = 75 years from Herne, Germany we measured bone T-scores with Dual-energy X-ray Absorptiometry, and functional status indexed by five geriatric tests: activities of daily living, instrumental activities of daily living, test of dementia, geriatric depression score and the timed-up-and-go test, and two pooled indexes: raw and standardized. Generalized linear regression was used to determine the relationship between T-scores and functional status. RESULTS: From 3243 addresses, only 632 (19% completed a clinical visit, of which only 440 (male:female, 243:197 could be included in analysis. T-scores (-0.99, 95% confidence interval [CI], -1.1-0.9 predicted activities of daily living (95.3 CI, 94.5-96.2, instrumental activities of daily living (7.3 CI, 94.5-96.2, and timed-up-and-go test (10.7 CI, 10.0-11.3 (P < = 0.05. Pooled data showed that a unit improvement in T-score improved standardized pooled functional status (15 CI, 14.7-15.3 by 0.41 and the raw (99.4 CI, 97.8-101.0 by 2.27 units. These results were limited due to pooling of different scoring directions, selection bias, and a need to follow-up with evidence testing. CONCLUSIONS: T-scores associated with lower functional status in community-dwelling elderly. Regular screening of osteoporosis as a preventive strategy might help maintain life quality with aging.

    A cross-sectional study was conducted to explore the prevalence and severity of health-related complaints perceived by adult males of Hong Kong by using the Hong Kong Traditional Chinese versions of the Aging males' symptoms (AMS) scale and the 5-dimensional and 3-level European Quality of life (EQ-5D-3L) questionnaire. A total of 825 adult males aged 40 years or above were surveyed, and observed that 80% of the population was living with little-to-mild levels of aging symptoms with mean total scores ranged between 26.02 ± 7.91 and 32.99 ± 7.91 in different age groups. Such symptoms were correlated with age, especially for the somato-vegetative and sexual symptoms. The most severe AMS symptoms were observed in the oldest age group at 70 years or above, with 76%, 34% and 70% living with moderate-to-severe levels of somato-vegetative, psychological and sexual symptoms, respectively. The result was highly correlated with the EQ-5D-3L questionnaire. Secondly, the Hong Kong Aging males' symptoms (AMS) scale was shown to have good reliability with test-retest coefficient at 0.79 (ranged 0.66-0.87) and Cronbach's alpha coefficient at 0.88 (ranged 0.70-0.84). In summary, the population of Hong Kong male adults was commonly living with little-to-mild levels of aging symptoms, whereas their severity was correlated with age. PMID:27068128

    Full Text Available Context: The views of fathers have been shown to be important determinants of infant feeding decisions, but men′s attitudes toward breastfeeding and formula feeding have rarely been explored. AIMS: To explore the relationship between maternal and paternal infant feeding attitudes and their impact on the duration of exclusive breastfeeding. Settings and Design: Prospective questionnaire-based cross-sectional study conducted in a tertiary care public hospital. Materials and Methods: From May 2009 to September 2010, a convenience sample of 238 parents of infants (>6 months to <1 year of age were included. Each parent′s attitude toward infant feeding was measured by the Iowa Infant Feeding Attitude Scale (IIFAS. Statistical Analysis Used: Pearson′s correlation test, independent samples t-test, and one-way analysis of variance were carried out for statistical significance. Results: Only 83 (34.9% mothers had exclusively breastfed their babies for 4-6 months. A mother′s "total" infant feeding attitude score was significantly correlated with her husband′s score ( r = 0.43, P < 0.01. The couples shared similar "individual" infant feeding attitudes to all but four of the 17 items. These 13 "individual" attitudes favorable toward breastfeeding were related to its optimal nutritional value, convenience of administration, ease of digestibility, unique role in mother-infant bonding, acceptability of breastfeeding in public places, and long-term health benefits to babies. Only maternal attitudes played an influential role in achieving an exclusive breastfeeding period of 4-6 months. Conclusions: Fathers′ attitudes do support breastfeeding, but do not influence the time duration of exclusive breastfeeding.

    Full Text Available Background: This cross-sectional, complete enumeration study was conducted in an urban slum to determine the frequency of occupational exposure of private medical practitioners to patient body fluids and the remedial measures adopted following such events and also to examine their high-risk practices, personal protective measures, immunisation and training status in relation to occupational exposures. Methods: After Institutional Ethics Committee approval, private medical practitioners practising for and #8805; 1 year in the locality who gave written informed consent were interviewed in their own clinics using a pre-tested formatted questionnaire. Results: Of the 108 respondents interviewed, the majority were non-allopathic, male practitioners. The speciality-wise and gender-wise differences in training in occupational exposure were not significant (p=0.135. Prior to disposal, 10.18% cut needles while 26.85% disinfected needles with 1% hypochlorite solution (p=0.0001. 50.93% never bent or recapped needles (p=0.0008. Only 19.44% regularly used gloves while examining patients (p=0.0039. 41.66% were completely unimmunised against Hepatitis B (p=0.004, while only one female non-allopathic practitioner (0.92% had taken complete immunisation against tetanus (p<0.05. Of the 7.41% respondents who had history of needle stick injuries, only one female non-allopathic practitioner had reported occupational exposure. Those unaware about the need for post-exposure prophylaxis for occupational exposure and that anti-retroviral therapy was part of post-exposure prophylaxis constituted 87.96% and 95.37%, respectively. Conclusions: Reporting of occupational exposure, complete immunisation against hepatitis B and tetanus and use of personal protection was inadequate. Specialised hands-on training ought to be an integral component of continuing medical education for private medical practitioners. [Int J Res Med Sci 2015; 3(12.000: 3708-3713

    Full Text Available Background: Breast cancer causes significant disruption to the quality of life (QOL of its patients, which is compounded further by lack of information and adequate facilities for rehabilitation. Materials and Methods: This descriptive cross-sectional study was conducted in women who had completed their Primary treatment of breast cancer. The QOL was assessed by Functional assessment of cancer therapy-breast (FACT-B version 4, and information and rehabilitation needs were enquired about in a semi-structured interview. Results: A total of 154 patients were enrolled and divided into three groups according to the time elapsed after initial treatment; Group I: 1-2 years, Group II: 2-5 years, Group III: >5 years The FACT-B mean scores were; Group I (n = 64: 79.06 ± 14.60; Group II (n = 48: 85.75 ± 20.15; and Group III (n = 42: 89.83 ± 12.80. Patients in Group I scored lowest on physical well-being subscale, Group II on breast specific subscale and Group III on Social well-being subscale. Pain, lack of energy, inability to meet the needs of the family, fear that the condition will get worse and loss of body image were significant factors contributing to poor QOL. Analysis of interviewshowed many unmet information needs. Main rehabilitation needs were effective treatment of physical symptoms and counselling about body image issues and sexual dysfunctions. Easy availability of clinical and social support services were major felt needs in the long-term follow-up. Conclusions: Targeted Interventions are needed to address issues relating to QOL and rehabilitation needs of breast cancer patients.

    Full Text Available Background: Metabolic syndrome also referred as cardio metabolic syndrome is identified as the prestate for cardiovascular disease, type 2 diabetes and also for chronic kidney disease. Obesity is considered as the strongest component of metabolic syndrome as per the definition given by different organizations. The easiest way to measure obesity are waist circumference, Body Mass Index (BMI and waist to hip ratio. Aims and Objective: To find the association between microalbuminuria and components of cardiometabolic syndrome in the bank employees and also the association between waist circumference, body mass index and components of cardiometabolic syndrome, microalbumin. Material and Methods: This was a cross sectional study involving 73 subjects working in a reputed bank. Their anthropometric measurements and biochemical parameters like fasting blood glucose, lipid profile, serum cortisol and microalbumin were measured. We defined microalbuminuria as a urinary albumin to creatinine ratio of 30 to 299 mg/gm. Results: out of 73 participants, in 33 participants at least 3-5 parameters of cardiometabolic syndrome were found to be present and were labeled as cardiometabolic syndrome patients. Waist circumference showed positive correlation with age (r=0.498, systolic blood pressure (r=0.500, diastolic blood pressure (r=0.476, fasting blood glucose (r=0.300, triglyceride (r=0.408 and microalbumin (r=0.409. Microalbumin also exhibited a significant positive correlation with age (r=0.404, waist circumference (r=0.419, fasting blood glucose (r=0.476 and HbA1c (r=0.466, while BMI showed negative correlation with microalbumin (r=-0.085. Conclusions: Obesity, one of the parameters of cardiometabolic syndrome measured as waist circumference, is indicative of the syndrome rather than BMI. Microalbumin may be considered as a promising parameter of cardiometabolic syndrome.

    Full Text Available Abstract Background Although most patients with hereditary haemochromatosis have HFE C282Y mutations, the lifetime risk to HFE C282Y homozygotes of developing fatal diseases such as hepatocellular carcinoma is uncertain. We have carried out a cross-sectional study to determine the proportion of diagnosed hepatocellular carcinoma patients who are homozygous for the HFE C282Y mutation; and to estimate the penetrance of this genotype with respect to hepatocellular carcinoma in East Anglia. Methods Tissue biopsies were analysed from 144 cases of hepatocellular carcinoma for HFE C282Y mutations; the data produced were compared with the frequency of HFE mutations in a large sample of the local population. Data were also retrieved from the East Anglian Cancer Intelligence Unit to determine the annual incidence of hepatocellular carcinoma; and from appropriate life tables. Results Eight out of 144 of the cases were homozygous for the HFE C282Y mutation, all 8 cases were male. 6 of these 8 cases had a previous diagnosis of hereditary haemochromatosis. Male HFE C282Y homozygotes were more likely to be diagnosed with hepatocellular carcinoma (odds ratio [OR] = 14, 95% confidence interval [CI] = 5–37. For this population, we estimate that the penetrance of the HFE C282Y homozygous genotype, with respect to hepatocellular carcinoma, was between 1.31 % and 2.1% for males and was zero for females. Conclusion In this population, we found that only a very small proportion of homozygotes for the HFE C282Y mutation developed hepatocellular carcinoma. However, individuals with this genotype have a significantly increased risk of this rare disease relative to those who do not carry the mutations.

    Full Text Available Abstract Background Physicians frequently report negative attitudes about obesity which is thought to affect patient care. However, little is known about how attitudes toward treating obese patients are formed. We conducted a cross-sectional survey of physicians in order to better characterize their attitudes and explore the relationships among attitudes, perceived competency in obesity care, including report of weight loss in patients, and other key physician, training, and practice characteristics. Methods We surveyed all 399 physicians from internal medicine, pediatrics, and psychiatry specialties at one institution regarding obesity care attitudes, competency, including physician report of percent of their patients who lose weight. We performed a factor analysis on the attitude items and used hierarchical regression analysis to explore the degree to which competency, reported weight loss, physician, training and practice characteristics explained the variance in each attitude factor. Results The overall response rate was 63%. More than 40% of physicians had a negative reaction towards obese patients, 56% felt qualified to treat obesity, and 46% felt successful in this realm. The factor analysis revealed 4 factors–Physician Discomfort/Bias, Physician Success/Self Efficacy, Positive Outcome Expectancy, and Negative Outcome Expectancy. Competency and reported percent of patients who lose weight were most strongly associated with the Physician Success/Self Efficacy attitude factor. Greater skill in patient assessment was associated with less Physician Discomfort/Bias. Training characteristics were associated with outcome expectancies with newer physicians reporting more positive treatment expectancies. Pediatric faculty was more positive and psychiatry faculty less negative in their treatment expectancies than internal medicine faculty. Conclusion Physician attitudes towards obesity are associated with competency, specialty, and years since

    Full Text Available Abstract Background Treatment delay is an important indicator of access to tuberculosis diagnosis and treatment. Analyses of patient delay (i.e. time interval between onset of symptoms and first consultation of a health care provider and health care delay (i.e. time interval between first consultation and start of treatment can inform policies to improve access. This study assesses the patient, health care provider and total delay in diagnosis and treatment of new smear-positive pulmonary tuberculosis patients, and the risk factors for long delay, in Vietnam. Methods A cross-sectional survey of new patients treated by the National Tuberculosis Control Programme was conducted in 70 randomly selected districts in Vietnam. All consecutively registered patients in one quarter of 2002 were interviewed using a pre-coded structured questionnaire. Results Median (range delay was 4 weeks (1–48 for total, 3 (1–48 weeks for patient and 1 (0–25 week for health care delay. Patients with long total delay (≥ 12 weeks, 15% accounted for 49% of the cumulative number of delay-weeks. Independent risk factors (p 5 km distance from a health facility or in the northern area. For long health care delay (≥ 6 weeks this was urban setting, residence in the central area and initial visit to a communal health post, TB hospital or the private sector. Conclusion Analyses of patient and treatment delays can indicate target groups and areas for health education and strengthening of the referral system, in particular between the private sector and the NTP.

    Objective To investigate estimation of calorie (energy) content of meals from fast food restaurants in adults, adolescents, and school age children. Design Cross sectional study of repeated visits to fast food restaurant chains. Setting 89 fast food restaurants in four cities in New England, United States: McDonald’s, Burger King, Subway, Wendy’s, KFC, Dunkin’ Donuts. Participants 1877 adults and 330 school age children visiting restaurants at dinnertime (evening meal) in 2010 and 2011; 1178 adolescents visiting restaurants after school or at lunchtime in 2010 and 2011. Main outcome measure Estimated calorie content of purchased meals. Results Among adults, adolescents, and school age children, the mean actual calorie content of meals was 836 calories (SD 465), 756 calories (SD 455), and 733 calories (SD 359), respectively. A calorie is equivalent to 4.18 kJ. Compared with the actual figures, participants underestimated calorie content by means of 175 calories (95% confidence interval 145 to 205), 259 calories (227 to 291), and 175 calories (108 to 242), respectively. In multivariable linear regression models, underestimation of calorie content increased substantially as the actual meal calorie content increased. Adults and adolescents eating at Subway estimated 20% and 25% lower calorie content than McDonald’s diners (relative change 0.80, 95% confidence interval 0.66 to 0.96; 0.75, 0.57 to 0.99). Conclusions People eating at fast food restaurants underestimate the calorie content of meals, especially large meals. Education of consumers through calorie menu labeling and other outreach efforts might reduce the large degree of underestimation. PMID:23704170

    Background The prevalence and the spectrum of thyroid dysfunction in the mainland of China are not adequately understood. We performed a population-based study to determine the prevalence of major thyroid dysfunctions including overt and subclinical hyper- and hypothyroidism in a stable cohort.Methods All active and retired employees aged 20 years and older (11 067) of Sinopec Zhenhai Refining & Chemical Company in Ningbo participated in the cross-sectional survey with a questionnaire and blood samples. Results A total of 10 405 individuals attended for screening. Using biochemical definitions 95.5% were euthyroid. The prevalence of former diagnosed hyperthyroidism was 1.1% in females and 0.4% in males, hypothyroidism 1.7% and 0.3%, and thyroid surgery 1.2% and 0.3%, respectively. In both sex the prevalence increased with age. Twenty-four percent of individuals with thyroid surgery or medications had abnormal thyroid-stimulating hormone (TSH) levels. In individuals without a history of thyroid disease, the prevalence of pathological TSH values in females and males were TSH ≥10 mU/L 0.60% and 0.29%; TSH 4.8-9.9 mU/L 5.71 % and 2.25%; TSH <0.3 mU/L 0.87% and 0.41 %, respectively. Overt hyper- and hypothyroidism were uncommon (0.2%, 0.3%, respectively). The prevalence of subclinical hyper- and hypothyroidism was 0.4% and 3.4%, respectively. Subclinical hypothyroidism was more common in females (male 2.4% vs. female 5.8%, P<0.001) and with increasing age (P<0.001).Conclusions The prevalence of thyroid dysfunction is 4.5% in the cohort. Among individuals with thyroid medications or surgery, only 75.7% were within the normal range of TSH. These results indicate that thyroid dysfunction is common in Chinese adults.

    Full Text Available Abstract Background Antibiotics sales without medical prescriptions are increasingly recognized as sources of antimicrobial misuse that can exacerbate the global burden of antibiotic resistance. We aimed to determine the percentage of pharmacies who sell antibiotics without medical prescriptions, examining the potential associated risks of such practice in Riyadh, Saudi Arabia, by simulation of different clinical scenarios. Methods A cross sectional study of a quasi-random sample of pharmacies stratified by the five regions of Riyadh. Each pharmacy was visited once by two investigators who simulated having a relative with a specific clinical illness (sore throat, acute bronchitis, otitis media, acute sinusitis, diarrhea, and urinary tract infection (UTI in childbearing aged women. Results A total of 327 pharmacies were visited. Antibiotics were dispensed without a medical prescription in 244 (77.6% of 327, of which 231 (95% were dispensed without a patient request. Simulated cases of sore throat and diarrhea resulted in an antibiotic being dispensed in (90% of encounters, followed by UTI (75%, acute bronchitis (73%, otitis media (51% and acute sinusitis (40%. Metronidazole (89% and ciprofloxacin (86% were commonly given for diarrhea and UTI, respectively, whereas amoxicillin/clavulanate was dispensed (51% for the other simulated cases. None of the pharmacists asked about antibiotic allergy history or provided information about drug interactions. Only 23% asked about pregnancy status when dispensing antibiotics for UTI-simulated cases. Conclusions We observed that an antibiotic could be obtained in Riyadh without a medical prescription or an evidence-based indication with associated potential clinical risks. Strict enforcement and adherence to existing regulations are warranted.

    Full Text Available In this cross-sectional study, we hypothesized that hemodialysis patients consuming greater processed meat is associated with hypertension risk, which can be partly explained by the high sodium content in processed meat. From September 2013 to May 2014, one hundred and four patients requiring chronic hemodialysis treatment were recruited from hemodialysis centers. Data on systolic blood pressure and diastolic blood pressure before receiving dialysis, and 3-day dietary records of the recruited patients were collected. HD patients with systolic and diastolic blood pressures greater than140 mmHg and higher than 90 mmHg, respectively, were considered hypertension risk. Protein foods were divided into 4 categories: red meat, white meat, soybeans, and processed meat (e.g., sausage and ham. In a model adjusted for energy intake and hypertension history, additional servings of processed meats was positively associated to systolic blood pressure >140 mmHg (odds ratio [95% confidence interval]: 2.1 [1.0-4.3], and diastolic blood pressure > 90 mmHg (odds ratio: 2.5 [1.2-5.5]. After adjustment for dietary sodium contents or body mass index (BMI, most associations were substantially attenuated and were no longer significant. In systolic blood pressure greater than140 mmHg, one serving per day of red meats (β = -1.22, P < .05 and white meats (β = -0. 75, P = .05 was associated with a reduced risk compared with one serving per day of processed meats. Similarly, compared with one serving per day of processed meat, a reduced risk of diastolic blood pressure higher than 90 mmHg was associated with one serving per day of red meat (β = -1. 59, P < .05, white meat (β = -0. 62, P < .05. Thus, in these hemodialysis patients, intake of processed meat is significantly positively associated with higher blood pressure risk, and both sodium contents in processed meat and BMI significantly contributes to this association.

    Full Text Available Abstract Background Injuries affect all age groups but have a particular impact on young people. To evaluate the incidence of non-fatal, unintentional, injuries among undergraduates in Wenzhou, China, assess the burden caused by these injuries, and explore the associated risk factors for unintentional injuries among these undergraduates, we conducted a college-based cross-sectional study. Methods Participants were selected by a multi-stage random sampling method, and 2,287 students were asked whether they had had an injury in the last 12 months; the location, cause, and consequences of the event. The questionnaire included demographic and socioeconomic characteristics, lifestyle habits, and the scale of type A behaviour pattern (TABP. Multivariate logistic regression models were used; crude odds ratios (ORs, adjusted ORs and their 95% confidence intervals (CIs were estimated, with students having no injuries as the reference group. Results The incidence of injuries among undergraduates in Wenzhou was 18.71 injuries per 100 person-years (95%CI: 17.12~20.31 injuries per 100 person-years. Falls were the leading cause of injury, followed by traffic injuries, and animal/insect bites. Male students were more likely to be injured than female students. Risk factors associated with unintentional injuries among undergraduates were: students majoring in non-medicine (adjusted OR: 1.53; 95% CI: 1.19-1.96; type A behaviour pattern (adjusted OR: 2.99; 95% CI: 1.45-6.14; liking sports (adjusted OR: 1.86; 95% CI: 1.41-2.45. Conclusions Injuries have become a public health problem among undergraduates. Falls were the major cause of non-fatal injury. Therefore, individuals, families, schools and governments should promptly adopt preventive measures aimed at preventing and controlling morbidity due to non-fatal injury, especially among students identified to be at high-risk; such as male students with type A behaviour pattern who like sports.

    While adverse conditions in a child's life do not excuse inappropriate behavior, they may cause emotional and behavioral problems that require treatment as a preventive measure to reduce the likelihood of bullying. We aimed to identify differences in the psychosocial profiles of adolescents who classified themselves as bullies, victims, or bully-victims. We performed a cross-sectional study in which data were collected between January 2009 and January 2010 from seven university-based clinics in a large metropolitan area with a predominantly Mexican-American population. We collected data on physical aggression among adolescents who self-categorized into the following groups: uninvolved, bullies, victims, and bully-victims. We determined the psychosocial profiles of the adolescents based on responses to the Youth Self Report (YSR) and parent's responses to the Child Behavior Checklist (CBCL). A one-way analysis of variance and multivariate regression analyses were performed to compare the various components of the psychosocial profiles among the groups. Our analysis of the CBCL and the YSR assessments identified differences between the uninvolved group and one or more of the other groups. No significant differences were observed among the bully, victim, and bully-victim groups based on the CBCL. We did find significant differences among those groups based on the YSR, however. Our results suggest that emotional and behavioral problems exist among bullies, victims, and bully-victims. Therefore, treatment should not focus only on the victims of bullying; treatment is equally important for the other groups (bullies and bully-victims). Failure to adequately treat the underlying problems experienced by all three groups of individuals could allow the problems of bullying to continue. PMID:24459665

    Introduction Prediabetes is an intermediate state between diabetes and normoglycaemia, where the glucose levels are higher than normal but not significant to be diagnosed as diabetes mellitus. Guidelines from various associations suggest different types of management in this situation. Objective To assess knowledge and attitude of the doctors regarding prediabetes using questionnaire. Materials and Methods A cross-sectional questionnaire based study was conducted to assess the knowledge, attitude and practice among doctors regarding prediabetes treatment. One hundred twenty two (of 150) filled questionnaires were received from general practitioners, post graduates (PGs), physicians and super specialists in and around Kolar and Bangalore. Data was analysed using descriptive statistics and expressed as percentage. Results A total of 81.3% responded to the questionnaire, of which 14 were general practitioners (MBBS), 48 PGs in General Medicine, 46 physicians (MD General Medicine), and 14 super specialists (DM). Knowledge response was 85.7% (definition – 100%, prevalence – 50.8%, approved drug- 45.2%, progression- 86.2%). Screening for prediabetes was done by 71% of the general practitioners and physicians, but specialists would screen all. 100% general practitioners, 97.9% post graduates, 91.3% of physicians and 64.2 % specialist preferred diet and exercise and rest of them opted for oral antidiabetic drug (OAD) along with diet and exercise, but none of the doctors considered OAD alone for prediabetes. Among OADs metformin (77.45%) was the most preferred followed by voglibose (20.6%) and sitagliptin (1.9%). Conclusion All doctors had awareness of prediabetes and most of them would regularly screen and treat prediabetes. Majority considered diet and exercise as first modality of treatment. The OAD opted commonly was metformin. PMID:26435963

    Full Text Available Occupational exposure to particulate air pollution has been associated with an increased risk of cardiovascular disease. However, the risk to welders working today remains unclear. We aimed to elucidate the cardiovascular effects of exposure to welding fumes.In a cross-sectional study, structured interviews and biological sampling were conducted for 101 welders and 127 controls (all non-smoking males from southern Sweden. Personal breathing zone sampling of respirable dust was performed. Blood pressure (BP and endothelial function (using peripheral arterial tonometry were measured. Plasma and serum samples were collected from peripheral blood for measurement of C-reactive protein, low-density lipoprotein, homocysteine, serum amyloid A, and cytokines.Welders were exposed to 10-fold higher levels of particles than controls. Welders had significantly higher BP compared to controls, an average of 5 mm Hg higher systolic and diastolic BP (P ≤ 0.001. IL-8 was 3.4 ng/L higher in welders (P=0.010. Years working as a welder were significantly associated with increased BP (β=0.35, 95%CI 0.13 - 0.58, P=0.0024 for systolic BP; β=0.32, 95%CI 0.16 - 0.48, P<0.001 for diastolic BP, adjusted for BMI but exposure to respirable dust was not associated with BP. No clear associations occurred between welding and endothelial function, or other effect markers.A modest increase in BP was found among welders compared to controls suggesting that low-to-moderate exposure to welding fumes remains a risk factor for cardiovascular disease.

    Full Text Available Background. Many Long-Term Care (LTC institutionalized patients are the most frail and functionally dependent among the geriatric population and have significant oral health disparities.They often suffer from dental neglect due to limited access to appropriate professional dental care. These patients have chronic health situations and are treated with medications, which increase their risk of oral diseases. Despite the growth in elderly population in Israel, there is insufficient data regarding their oral health status and treatment needs. Objective. To describe the oral health status of the LTC hospitalized adults in a geriatric and psychiatric hospital in Israel. Methods. Data was recorded from LTC hospitalized adults with a physical and/or mental disabilities in a cross-sectional research design, which included general health anamnesis and clinical oral examination. Variables included gender, medicines, oral hygiene (OH, using dentures, number of caries lesions and residual teeth. Univariate analyses included Pearson χ2 and t-test analyses. Multivariate analyses included logistic and linear regressions while the outcome variables were categorical OH index and number of carious cavitations, number of residual teeth and carious teeth percentage. Results. 153 participants were included in the study with a mean age of 65.03 ± 18.67 years. 31.3% of the patients were edentulous, and only 14% had partial or full dentures. Females had a significantly higher number of caries cavitation than males (P = 0.044. The number of caries cavitation was higher among patients with poor OH (P < 0.001 and when taking Clonazepam (P = 0.018. Number of residual teeth was higher in the fair OH group (P < 0.001. Carious teeth percentage was higher among the poor OH group (P < 0.001.

    Abstract Objective To propose an antenatal care classification for measuring the continuum of health care based on the concept of adequacy: timeliness of entry into antenatal care, number of antenatal care visits and key processes of care. Methods In a cross-sectional, retrospective study we used data from the Mexican National Health and Nutrition Survey (ENSANUT) in 2012. This contained self-reported information about antenatal care use by 6494 women during their last pregnancy ending in live birth. Antenatal care was considered to be adequate if a woman attended her first visit during the first trimester of pregnancy, made a minimum of four antenatal care visits and underwent at least seven of the eight recommended procedures during visits. We used multivariate ordinal logistic regression to identify correlates of adequate antenatal care and predicted coverage. Findings Based on a population-weighted sample of 9 052 044, 98.4% of women received antenatal care during their last pregnancy, but only 71.5% (95% confidence interval, CI: 69.7 to 73.2) received maternal health care classified as adequate. Significant geographic differences in coverage of care were identified among states. The probability of receiving adequate antenatal care was higher among women of higher socioeconomic status, with more years of schooling and with health insurance. Conclusion While basic antenatal care coverage is high in Mexico, adequate care remains low. Efforts by health systems, governments and researchers to measure and improve antenatal care should adopt a more rigorous definition of care to include important elements of quality such as continuity and processes of care.

    Full Text Available Despite recent improvements in child survival in sub-Saharan Africa, neonatal mortality rates remain largely unchanged. This study aimed to determine the frequency of delivery and newborn-care practices in southern Tanzania, where neonatal mortality is higher than the national average. All households in five districts of Southern Tanzania were approached to participate. Of 213,220 female residents aged 13-49 years, 92% participated. Cross-sectional, retrospective data on childbirth and newborn care practices were collected from 22,243 female respondents who had delivered a live baby in the preceding year. Health facility deliveries accounted for 41% of births, with nearly all non-facility deliveries occurring at home (57% of deliveries. Skilled attendants assisted 40% of births. Over half of women reported drying the baby and over a third reported wrapping the baby within 5 minutes of delivery. The majority of mothers delivering at home reported that they had made preparations for delivery, including buying soap (84% and preparing a cloth for drying the child (85%. Although 95% of these women reported that the cord was cut with a clean razor blade, only half reported that it was tied with a clean thread. Furthermore, out of all respondents 10% reported that their baby was dipped in cold water immediately after delivery, around two-thirds reported bathing their babies within 6 hours of delivery, and 28% reported putting something on the cord to help it dry. Skin-to-skin contact between mother and baby after delivery was rarely practiced. Although 83% of women breastfed within 24 hours of delivery, only 18% did so within an hour. Fewer than half of women exclusively breastfed in the three days after delivery. The findings suggest a need to promote and facilitate health facility deliveries, hygienic delivery practices for home births, delayed bathing and immediate and exclusive breastfeeding in Southern Tanzania to improve newborn health.

    The purpose of this study was to test a comprehensive model of meal portion size determinants consisting of sociodemographic, psychological and food-related variables, whilst controlling for hunger and thirst. Using cross-sectional nationally representative data collected in 2075 participants from the Island of Ireland (IoI) and Denmark (DK), eight separate hierarchical multiple regression analyses were conducted to examine the association between food-related variables and meal portion size (i.e. pizza, vegetable soup, chicken salad and a pork meal) within each country. Stepwise regressions were run with physiological control measures (hunger and thirst) entered in the first step, sociodemographic variables (sex, age, body mass index (BMI)) in the second step; psychological variables (cognitive restraint, uncontrolled eating, emotional eating, general health interest (GHI)) in the third step and food-related variables (expected fillingness, liking, expected healthfulness, food familiarity) in the fourth step. Sociodemographic variables accounted for 2-19% of the variance in meal portion sizes; psychological variables explained an additional 3-8%; and food-related variables explained an additional 2-12%. When all four variable groups were included in the regression models, liking and sometimes expected healthfulness was positively associated with meal portion size. The strongest association was for liking, which was statistically significant in both countries for all meal types. Whilst expected healthfulness was not associated with pizza portion size in either country, it was positively associated with meals that have a healthier image (vegetable soup; chicken salad and in IoI, the pork meal). In conclusion, after considering sociodemographic and psychological variables, and the food-related variables of liking and expected healthfulness, there may be little merit in manipulating the satiating power, at least of these type of meals, to maintain or promote weight

    Background While Group B Streptococcus (GBS) human colonization and infection has long been suspected as originating from cows, several investigators have suggested that ongoing interspecies GBS transmission is unlikely due to genotyping data demonstrating that human and bovine-derived GBS strains represent mostly distinct populations. The possibility of ongoing transmission between humans and their livestock has not been systematically examined. Methodology/Principal Findings To examine ongoing interspecies transmission, we conducted a prospective cross-sectional cohort study of 68 families and their livestock. Stool specimens were collected from 154 people and 115 livestock; GBS was detected in 19 (12.3%) humans and 2 (1.7%) animals (bovine and sheep). Application of multilocus sequence typing (MLST) identified 8 sequence types (STs or clones), with STs 1 and 23 predominating. There were 11 families in which two members submitted stools and at least one had GBS colonization. In 3 of these families, both members (consisting of couples) were colonized, yielding a co-colonization rate of 27% (95% CI: 7%–61%). Two of these couples had strains with identical MLST, capsule (cps) genotype, susceptibility, and RAPD profiles. One couple co-colonized with ST-1 (cps5) strains also had a bovine colonized with the identical strain type. On multivariate analysis of questionnaire data, cattle exposure was a predictor of GBS colonization, with each unit increase in days of cattle exposure increasing the odds of colonization by 20% (P = 0.02). These results support interspecies transmission with additional evidence for transmission provided by the epidemiological association with cattle exposure. Conclusions/Significance Although GBS uncommonly colonizes livestock stools, increased frequency of cattle exposure was significantly associated with human colonization and one couple shared the same GBS strains as their bovine suggesting intraspecies transmission.

    Full Text Available Background: Evidence from three randomised control trials in South Africa, Uganda and Kenya showing that male circumcision can reduce heterosexual transmission of human immunodeficiency virus (HIV infection from infected females to their male partners by up to 60% has led to an increase in circumcisions in most African countries. This has created anxieties around possible deleterious effects of circumcision on erectile function (EF.Aim: To compare EF in circumcised and uncircumcised men aged 18 years and older.Setting: Four primary healthcare facilities in Lusaka, Zambia.Methods: Using a cross-sectional survey 478 participants (242 circumcised and 236 uncircumcised from four primary healthcare facilities in Lusaka, Zambia were asked to complete the IIEF-5 questionnaire. EF scores were calculated for the two groups, where normal EF constituted an IIEF-5 score ≥ 22 (out of 25.Results: Circumcised men had higher average EF scores compared to their uncircumcised counterparts, (p < 0.001. The prevalence of erectile dysfunction was lower in circumcisedmen (56% compared to uncircumcised men (68% (p < 0.05. EF scores were similar in thosecircumcised in childhood and those who had the procedure in adulthood, (p = 0.59. The groups did not differ significantly in terms of age, relationship status, smoking, alcohol and medication use. A statistically significant difference was observed in education levels, with the circumcision group having higher levels of education (p < 0.005.Conclusion: The higher EF scores in circumcised men show that circumcision does not confer adverse EF effects in men. These results suggest that circumcision can be considered safe interms of EF. A definitive prospective study is needed to confirm these findings.

    Full Text Available BACKGROUND: Male circumcision (MC has been shown to reduce the risk of female to male transmission of HIV. The goal of this survey was to explore the acceptability of MC among the Chinese and to identify factors associated with circumcision preference. METHODS: A cross-sectional survey was conducted between September 2009 and December 2010. We interviewed 2,219 male community participants, from three high HIV prevalence provinces in western China. A structured questionnaire was used to collect data on MC knowledge, willingness to accept MC, reasons to accept or refuse MC, and sexual behaviors and health. For those who refused MC, a health education intervention providing information on the benefits of circumcision was conducted. We used multiple logistic regression models to identify factors associated with the acceptability of MC. RESULTS: Of the respondents (n = 2,219, 44.6% (989/2,219 reported they would accept MC for the following reasons: promotion of female partners' hygiene (60.3%, redundant foreskin (59.4%, prevention of penile cancer (50.2%, enhanced sexual pleasure (41.4%, and protection against HIV and STDs (34.2%. The multivariable logistic regression showed that five factors were associated with MC willingness: long foreskin (OR = 15.98, residing in Xinjiang province (OR = 3.69, being younger than 25 (OR = 1.60, knowing hazards of redundant foreskin (OR = 1.78, and having a friend who underwent circumcision (OR = 1.36. CONCLUSION: The acceptability of male circumcision was high among the general population in China. Our study elucidates the factors associated with circumcision preference and suggests that more health education campaigns about positive health effects are necessary to increase the MC rate in China.

    Objectives To estimate the correlation between osteoporosis and vascular calcification in postmenopausal women and the influence of calcium/vitamin D supplements on vascular calcification. Methods A cross-sectional study was performed including 29 women with osteoporosis (15 not taking supplements) and 18 age-matched, non-osteoporotic women. They were evaluated for cardiovascular risk factors and blood tests, lateral X-ray of lumbar spine (assessment of abdominal aorta calcification, AAC) and carotid ultrasound (increased intima media thickness (iIMT) or calcified plaques) were performed. Results In univariate analysis, osteoporotic women were 16 times more likely to develop AAC (odds ratio (OR) 15.8, 95% confidence interval (CI) 1.9-135.4) and seven times more likely to develop iIMT (OR 6.8, 95% CI 1.8-25.4) compared to normal individuals. The odds of developing AAC and iIMT were increased each year after menopause (OR 1.11, 95% CI 1.01-1.2 and OR 1.18, 95% CI 1.05-1.3, respectively) and with aging (OR 1.27, 95% CI 1.1-1.47 and OR = 1.17, 95% CI 1.04-1.3, respectively). Calcified plaques were significantly correlated with osteoporosis (p = 0.014). In multivariate analysis, osteoporosis was an independent risk factor for AAC (OR 13.3, 95% CI 1.3-134.4) and iIMT (OR 4.7, 95% CI 1.1-19.9). Low doses of supplements did not appear to affect vascular calcification (p = 0.6). Conclusions Osteoporosis is associated with increased calcification of the abdominal aorta and carotids. Low doses of supplements do not appear to cause any increase in vascular calcification in osteoporotic women. PMID:27045323

    Full Text Available OBJECTIVE: Recent evidence suggests that non-alcoholic fatty liver disease is associated with diet. Our aim was to investigate the dietary patterns of a Brazilian population with this condition and compare them with the recommended diet. METHODS: A cross-sectional study was conducted on 96 non-alcoholic fatty liver disease patients before any dietetic counseling. All patients underwent abdominal ultrasound, biochemical tests, dietary evaluations, and anthropometric evaluations. Their food intake was assessed by a semi-quantitative food-frequency questionnaire and 24-hour food recall. RESULTS: The median patient age was 53 years, and 77% of the individuals were women. Most (67.7% participants were obese, and a large waist circumference was observed in 80.2% subjects. Almost 70% of the participants had metabolic syndrome, and 62.3% presented evidence of either insulin resistance or overt diabetes. Most patients (51.5, 58.5, and 61.7%, respectively exceeded the recommendations for energy intake, as well as total and saturated fat. All patients consumed less than the amount of recommended monounsaturated fatty acids, and 52.1 and 76.6% of them consumed less polyunsaturated fatty acids and fiber, respectively, than recommended. In most patients, the calcium, sodium, potassium, pyridoxine, and vitamin C intake did not meet the recommendations, and in 10.5-15.5% of individuals, the tolerable upper limit intake for sodium was exceeded. The patients presented a significantly high intake of meats, fats, sugars, legumes (beans, and vegetables and a low consumption of cereals, fruits, and dairy products compared with the recommendations. CONCLUSIONS: Although patients with non-alcoholic fatty liver disease exhibited high energy and lipid consumption, most of them had inadequate intake of some micronutrients. The possible role of nutrient-deficient intake in the development of non-alcoholic fatty liver disease warrants investigation.

    Most studies on the prevalence of back pain have evaluated it in developed countries (Human Development Index-HDI > 0.808), and their conclusions may not hold for developing countries. The aim of this study was to identify the prevalence of back pain in representative Brazilian athletes from public high schools. This cross-sectional study was performed during the state phase of the 2015 Jogos dos Institutos Federais (JIF), or Federal Institutes Games, in Brazil (HDI = 0.744), and it enrolled 251 athletes, 173 males and 78 females (14-20 years old). The dependent variable was back pain, and the independent variables were demographic, socioeconomic, psychosocial, hereditary, exercise-level, anthropometric, strength, behavioral, and postural factors. The prevalence ratio (PR) was calculated using multivariable analysis according to the Poisson regression model (α = 0.05). The prevalence of back pain in the three months prior to the study was 43.7% (n = 104), and 26% of the athletes reported feeling back pain only once. Multivariable analysis showed that back pain was associated with demographic (sex), psychosocial (loneliness and loss of sleep in the previous year), hereditary (ethnicity, parental back pain), strength (lumbar and hand forces), anthropometric (body mass index), behavioral (sleeping time per night, reading and studying in bed, smoking habits in the previous month), and postural (sitting posture while writing, while on a bench, and while using a computer) variables. Participants who recorded higher levels of lumbar and manual forces reported a lower prevalence of back pain (PR 1.30). In conclusion, there is no association between exercise levels and back pain but there is an association between back pain and non-exercise related variables. PMID:26938456

  12. A study on the distribution of polystyrene sulfonic acid grafts over the cross-section of a PFA film

    International Nuclear Information System (INIS)

    In this study, the distribution behaviors of polystyrene sulfonic acid (PSSA) grafts over the cross-section of grafted PFA membranes (PFA-g-PSSA) were investigated by using SEM-EDX analysis. Membranes with various degrees of grafting (DOG) and thicknesses were prepared by a simultaneous radiation grafting of styrene and a subsequent sulfonation with chlorosulfonic acid. A SEM-EDX instrument was utilized to directly observe that the distribution behaviors of the PSSA grafts over the cross-section of grafted PFA membranes and the results showed that the distribution behaviors were largely affected by the grafting conditions such as the degree of grafting, monomer concentration, and film thickness.

    Full Text Available The objective of the study was to evaluate the knowledge of pharmacists and check their conduct in relation to dispensing of drugs. This is a cross-sectional study performed in four municipalities from South and Southeast of Brazil, which are reference in health national scenario and concentrate 73.6% of national economic activity. Pharmacists who works in community pharmacies were invited to answer a questionnaire prepared by the authors of this study and validated. The main outcome measured was the pharmaceutical knowledge, rated according to the number of correct answers on that questionnaire prepared by the researchers, and professional conduct in relation to dispensing of drugs. The data collection occurred from September to December 2012 and the information obtained were tabulated in duplicate by two independent researchers for later analysis. 486 community pharmacies were visited but only 112 professionals participated in the study. Among the participants, 78.6% (n = 88 did not have adequate knowledge to perform the dispensing of drugs, despite this same number of pharmacists claiming to have participated in conferences and courses after graduation. The main sources of information on drugs used by participants have a low level of scientific evidence. The performance of non-employment related tasks reduces the time available for the care of medication users. In addition, the indiscriminate sale of antimicrobials and the sale of products other than health, mischaracterize the role of the pharmacist in the community pharmacy. There are gaps in the knowledge of professionals, limiting the satisfactory completion of dispensing of drugs. In addition, the excess of other duties and inadequate professional conduct compromise the promotion of the rational use of drugs.

    Full Text Available Abstract Background Smear negative pulmonary tuberculosis (SNPT accounts for 30% of pulmonary tuberculosis cases reported yearly in Brazil. This study aimed to develop a prediction model for SNPT for outpatients in areas with scarce resources. Methods The study enrolled 551 patients with clinical-radiological suspicion of SNPT, in Rio de Janeiro, Brazil. The original data was divided into two equivalent samples for generation and validation of the prediction models. Symptoms, physical signs and chest X-rays were used for constructing logistic regression and classification and regression tree models. From the logistic regression, we generated a clinical and radiological prediction score. The area under the receiver operator characteristic curve, sensitivity, and specificity were used to evaluate the model's performance in both generation and validation samples. Results It was possible to generate predictive models for SNPT with sensitivity ranging from 64% to 71% and specificity ranging from 58% to 76%. Conclusion The results suggest that those models might be useful as screening tools for estimating the risk of SNPT, optimizing the utilization of more expensive tests, and avoiding costs of unnecessary anti-tuberculosis treatment. Those models might be cost-effective tools in a health care network with hierarchical distribution of scarce resources.

    Full Text Available Abstract Background Late presentation of patients at advanced stages when little or no benefit can be derived from any form of therapy is the hallmark of breast cancer in Nigerian women. Recent global cancer statistics indicate rising global incidence of breast cancer and the increase is occurring at a faster rate in populations of the developing countries that hitherto enjoyed low incidence of the disease. Worried by this prevailing situation and with recent data suggesting that health behavior may be influenced by level of awareness about breast cancer, a cross-sectional study was designed to assess the knowledge, attitude and practices of community-dwelling women in Nigeria towards breast cancer. Methods One thousand community-dwelling women from a semi-urban neighborhood in Nigeria were recruited for the study in January and February 2000 using interviewer-administered questionnaires designed to elicit sociodemographic information and knowledge, attitude and practices of these women towards breast cancer. Data analysis was carried out using Statistical Analysis Software (SAS version 8.2. Results Study participants had poor knowledge of breast cancer. Mean knowledge score was 42.3% and only 214 participants (21.4% knew that breast cancer presents commonly as a painless breast lump. Practice of breast self examination (BSE was low; only 432 participants (43.2% admitted to carrying out the procedure in the past year. Only 91 study participants (9.1% had clinical breast examination (CBE in the past year. Women with higher level of education (X2 = 80.66, p 2 = 47.11, p Conclusion The results of this study suggest that community-dwelling women in Nigeria have poor knowledge of breast cancer and minority practice BSE and CBE.

    This study compared adolescents' self-perceived need for orthodontic treatment with the normative need for such treatment and investigated associations between socioeconomic and demographic variables and self-perceptions of dental malocclusion. This cross-sectional study involved 1015 schoolchildren aged 12-15 years in São Luís, Maranhão, Brazil. The following data were collected using a questionnaire and an orthodontic examination card: demographic and identifying data, socioeconomic data, educational levels of family, household income, economic classification criteria, and self-reported skin color behavioral data, and oral health data. Normative occlusal condition was examined using the Angle classification and Dental Aesthetic Index (DAI). Data were analyzed using the chi-squared test (to analyze differences in the frequency distribuition of qualitative variables) and Poisson regression (to stimate associations between the perceived need of orthodontic treatment and study covariates), with a 5% significance level. Schoolchildren's self-perceived need for orthodontic treatment was associated with sex (p = 0.022) and the normative need for treatment (p = 0.004). Among socioeconomic, demographic, and oral health variables, only sex [prevalence ratio (PR) = 1.15; 95% confidence interval (95%CI) = 1.04-1.28; p = 0.009] and the normative need for orthodontic treatment (PR = 1.19; 95%CI = 1.08-1.32; p malocclusion, with female adolescents reporting a greater need for orthodontic treatment. Female adolescents seems to be more sensitive to oral health problems. The results suggest that the DAI score might reflect a self-perceived need for orthodontic treatment and the Angle classification might overestimate the orthodontic treatment need. PMID:27253139
