    Cognitive and functional geriatric assessment may change in acromegaly. Herein we aimed to determine at which points geriatric assessment of the cases with acromegaly differs from that of general elderly population. In this comparative cross-sectional study, a total of 30 cases with acromegaly (controlled n = 14, uncontrolled n = 16) and 30 gender and body-mass index-matched cases without acromegaly (control group, CG) above 60 years old were included. Cognitive functions were evaluated on the basis of the mini-mental state exam (MMSE). Affective status was determined using the geriatric depression scale. Activities of daily living (ADL) were ranked according to the Barthel index while instrumental activities of daily living (IADL) were graded on the basis of the Lawton scale. Nutritional status was evaluated using the mini-nutritional assessment (MNA). Body composition was measured through bioimpedance analysis. Functional mobility was determined using the Timed Up and Go test (TUG) and muscle strength with the handgrip strength test. Scores on the MMSE were significantly lower in the elderly cases with acromegaly than in the cases without acromegaly (p < 0.001). Dementia was more frequent in the acromegaly group than in the CG (p = 0.04). Total MNA scores were significantly lower in cases with acromegaly than in the CG (p = 0.006). More subjects in the acromegaly group (33%) were at greater risk of malnutrition than in the CG (3%) (p = 0.003). There was greater moderate functional impairment based on Barthel ADL in the acromegaly group than in the CG (p = 0.04). Acromegaly may impair cognitive functions, functional mobility and instrumental daily living activities in the geriatric population. With acromegaly, the risk of malnutrition may also increase.

    Collagenous sprue (CS) is a rare enteropathy characterized by villous atrophy and a thickened subepithelial collagen band. The aim of this study is to describe the cross-sectional imaging findings of CS. A case-control, retrospective study with cases of all CS patients from January 2000 to 2015 was performed. Inclusion criteria were (1) Histopathologic diagnosis and (2) Imaging with computed tomography abdomen/pelvis (CT A/P), CT enterography (CTE), or magnetic resonance enterography within 6 months of small bowel (SB) biopsy. Control subjects were irritable bowel syndrome (IBS) patients who underwent CTE. Imaging studies were examined by two GI radiologists, blinded to patient data. 108 patients (54 CS; 54 IBS) were included. Mean age was 56.7 ± 16.5 years, and 68% were female (72% in CS group vs. 63% in IBS group; p = 0.3). CS patients were significantly older (67 ± 12 vs. 47 ± 15 year; p reversal (46% vs. 6%; p < 0.001), SB dilation (28% vs. 0%; p < 0.001), SB conformational change (28% vs. 6%; p = 0.002), SB wall thickening (13% vs. 2%; p = 0.03), and ulcerative jejunoileitis (4% vs. 0%; p = 0.01). Radiologists suspected malabsorption in 72% in the CS group and 2% in the IBS group (p < 0.001). Imaging findings suggestive of mucosal malabsorption are commonly demonstrated in CS.

    This comparative cross-sectional study examines the association between traffic congestion and elevation of systolic and/or diastolic blood pressure levels among a convenience sample of 310 drivers. Data collection took place during a gas station pause at a fixed time of day. Higher average systolic (142 vs 123 mm Hg) and diastolic (87 vs 78 mm Hg) blood pressures were detected among drivers exposed to traffic congestion compared with those who were not exposed (P<.001), while controlling for body mass index, age, sex, pack-year smoking, driving hours per week, and occupational driving. Moreover, among persons exposed to traffic congestion, longer exposure time was associated with higher systolic and diastolic blood pressures. Further studies are needed to better understand the mechanisms of the significant association between elevated blood pressure and traffic congestion. ©2017 Wiley Periodicals, Inc.

    It has been shown that empathy strengthens the relationship between patients and health professionals and also improves patient and health professional satisfaction, which helps promote the best clinical outcomes. Empathy is considered an essential prerequisite for a nurse to effectively care for a patient and for a holistic understanding of a patient's perspective in a student population. The main aim was to compare empathy levels between health professional students attending different university courses. A comparative study with a cross-sectional approach was conducted in two successive academic year cohorts of 1st year health professional students at a public Italian university. A sample of 1st year health professional students at a public Italian university was investigated using the Jefferson Scale of Empathy Health Professional Students version (JSE-HPS). Overall, 502 health professional students were included in the study. The students in nursing showed significantly higher empathy levels than the students in other health professions. Furthermore, the female students were found to exhibit significantly more overall empathy than the male students were. The undergraduate nursing students showed a significantly higher mean score of empathy measured by the Jefferson Scale of Empathy Health Professional Students version (JSE-HPS) than the students attending other health undergraduate courses. This could mean that a particular aptitude in establishing a help-relationship with other people exists among the students that choose to become a nurse. Copyright © 2016 Elsevier Ltd.

    Full Text Available Abstract Background Pressure ulcers are a common, painful and costly condition. Results of a 1991 study into the knowledge among Dutch hospital nurses on the usefulness of measures to prevent pressure ulcers showed moderate knowledge. Results were confirmed by subsequent studies. In recent years, Dutch guidelines have been updated and the attention given to pressure ulcer care has been increased. This was expected to improve pressure ulcer care and to increase nurses' knowledge. The aims of the current study were to investigate (1 how much nurses employed in Dutch hospitals know about the usefulness of 28 preventive measures considered in the most recent national pressure ulcer guideline; (2 whether differences in knowledge exist between nurses working in hospitals that audit pressure ulcers and those employed in hospitals that do not; and (3 to study whether knowledge among Dutch hospital nurses regarding the usefulness of preventive measures had changed between 1991 and 2003. Methods A cross-sectional study design among nurses employed in Dutch hospitals in 2003 was used to investigate their knowledge and differences in knowledge between nurses employed in different types of institution. A comparative design was used to assess whether knowledge differed between this population and that of Dutch hospital nurses in 1991. The nurses' knowledge was assessed by a written questionnaire. Data of 522 respondents meeting the inclusion criteria were analyzed and compared with the results of the 351 nurses included in the 1991 study. Results Knowledge in 2003 was slightly better than that in 1991. The nurses were moderately aware of the usefulness of preventive measures. Nurses employed in organizations that monitored pressure ulcers did not display greater knowledge than those employed in organizations that did not do so. Conclusion Knowledge among Dutch hospital nurses about the usefulness of measures to prevent pressure ulcers seems to be moderate

    Objectives Maternal satisfaction during the birthing process has been well documented, whereas little is known about the fathers’ birth experiences. Our objective was to evaluate and compare the birth satisfaction of mothers and fathers. Design Comparative cross-sectional study. Setting Number of participating centres: one level III maternity centre (2813 births in 2011) in Sherbrooke, Quebec, Canada. Participants 200 mothers and 200 accompanying fathers/mother's partner recruited 12–24 h after the birth over a 6-week period. Primary and secondary outcome measures The Birth Satisfaction Scale (BSS) was used for the mother, and it was adapted to the father's perspective. Paired-samples t tests were used for comparing mothers and fathers for the BSS global and thematic scores. Multiple linear regressions (forward stepwise method) were made to identify predicting factors of mothers’ and fathers’ satisfaction. Results Global satisfaction scores for mothers (115.5/150) and fathers (114.4/150) were relatively high and similar (p=0.116). The analysis of subthemes showed that more distress during childbirth was reported by mothers (psatisfaction (psatisfaction predictor. For mothers, other satisfaction predictors were labour length, tearing and type of anaesthesia used in caesarean section. For fathers, lower satisfaction predictors were instrumental delivery, primary caesarean delivery and infant's distress factors after caesarean section. Conclusions This study highlights differences in mothers’ and fathers’ birth satisfaction and in their predictors. It is thus important to take into account the birth experience of each parent and to support parents accordingly by adapting care provision surrounding childbirth. More research on this topic from the prenatal to the postnatal period is suggested, as it might have an impact on parents’ satisfaction and on early parenthood experience. PMID:24566529

    To examine eating difficulties among stroke patients - a comparison between women and men. Gender differences have been reported in studies of stroke, but the findings are inconclusive and few of these studies have specifically focused on gender differences in eating difficulties. This study was a descriptive, cross-sectional, comparative study. Patients with stroke were recruited at a general hospital in Sweden. To detect eating difficulties, individual observations of the patients were made during one meal using a structured observation protocol. Assessment also included measurements of nutritional and oral status, degree of independence, stroke severity, neglect and well-being. One hundred and four patients (53·8% women) were included in the study. The proportion of stroke patients with one or more eating difficulties was 81·7%. The most common eating difficulties were 'managing food on the plate' (66·3%), 'food consumption' (54·8%) and 'sitting position' (45·2%). Women had lower 'food consumption', more severe stroke (p = 0·003), worse functional status (p = 0·001) and lower quality of life (QoL) (p=0·038) than men. More women than men were malnourished and living alone. After adjustment for functional status and motor arm, the odds ratio of having difficulties with food consumption was four times higher among women than men (1·7-9·4, confidence interval 95%). More women than men with stroke suffered from inadequate food consumption. The women had more severe strokes, experienced poorer QoL and showed lower functional status than the men. In the rehabilitation process of women with stroke, these factors should be taken into consideration. Structured observation of meals, including assessment of food consumption, might be necessary in acute stroke care to detect patients, especially women, who might need closer supervision and nutritional intervention. © 2011 Blackwell Publishing Ltd.

    Full Text Available Background. The objectives of this study were to determine the burden of underweight and intestinal parasitic infection in the urban and rural elementary school children. Methods. A comparative cross-sectional study design was conducted. Binary logistic regression was used to identify the determinants of malnutrition or intestinal parasites. Two independent samples’ t-test was used to identify the effect of malnutrition on school performance or hemoglobin level. Results. A total of 2372 students were included. Quarters (24.8% of school children were underweight. Underweight was associated with sex [adjusted odds ratio (AOR 0.61; 95% CI = 0.47–0.78], age [AOR = 0.21; 95% CI = 0.16–0.28], intestinal parasitic infection [AOR 2.67; 95% CI = 2–3.55], and family size [AOR 23; 95% CI = 17.67–30.02]. The prevalence of intestinal parasite among school children was 61.7% [95% CI = 60%–64%]. Shoe wearing practice [AOR 0.71; 95% CI = 0.58–0.87], personal hygiene [AOR 0.8; 95% CI = 0.65–0.99], availability of latrine [AOR 0.34; 95% CI = 0.27–0.44], age [AOR 0.58; 95% CI = 0.48–0.7], habit of eating raw vegetables [AOR 3.71; 95% CI = 3.01–4.46], and family size [AOR 1.96; 95% CI = 1.57–2.45] were the predictors of intestinal parasitic infection.

    To study insight correlates in schizophrenia and bipolar mood disorder in remission among out-patients attending the Psychiatry Department of a Tertiary Care Hospital. 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. 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. 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. 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. 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.

    Background Freon includes a number of gaseous, colorless chlorofluorocarbons. Although freon is generally considered to be a fluorocarbon of relatively low toxicity; significantly detrimental effects may occur upon over exposure. The purpose of the present study is to investigate whether occupational exposure to fluorocarbons can induce arterial hypertension, myocardial ischemia, cardiac arrhythmias, elevated levels of plasma lipids and renal dysfunction. Methods This comparative cross-sectional study was conducted at the cardiology clinic of the Suez Canal Authority Hospital (Egypt). The study included 23 apparently healthy male workers at the refrigeration services workshop who were exposed to fluorocarbons (FC 12 and FC 22) and 23 likewise apparently healthy male workers (unexposed), the control group. All the participants were interviewed using a pre-composed questionnaire and were subjected to a clinical examination and relevant laboratory investigations. Results There were no significant statistical differences between the groups studied regarding symptoms suggesting arterial hypertension and renal affection, although a significantly higher percentage of the studied refrigeration services workers had symptoms of arrhythmias. None of the workers had symptoms suggesting coronary artery disease. Clinical examination revealed that the refrigeration services workers had a significantly higher mean pulse rate compared to the controls, though no significant statistical differences were found in arterial blood pressure measurements between the two study groups. Exercise stress testing of the workers studied revealed normal heart reaction to the increased need for oxygen, while sinus tachycardia was detected in all the participants. The results of Holter monitoring revealed significant differences within subject and group regarding the number of abnormal beats detected throughout the day of monitoring (p < 0.001). There were no significant differences detected in the

    Full Text Available Rural populations in low-income countries commonly suffer from the co-morbidity of neglected tropical diseases (NTDs. Podoconiosis, trachomatous trichiasis (both NTDs and cataract are common causes of morbidity among subsistence farmers in the highlands of northern Ethiopia. We explored whether podoconiosis was associated with cataract or trachomatous trichiasis (TT among this population.A comparative cross-sectional study was conducted in East Gojam region, Amhara, Ethiopia in May 2016. Data were collected from patients previously identified as having podoconiosis and from matched healthy neighbourhood controls. Information on socio-demographic factors, clinical factors and past medical history were collected by an interview-administered questionnaire. Clinical examination involved grading of podoconiosis by examination of both legs, measurement of visual acuity, direct ophthalmoscopy of dilated pupils to grade cataract, and eyelid and corneal examination to grade trachoma. Multiple logistic regression was conducted to estimate independent association and correlates of podoconiosis, TT and cataract.A total of 700 participants were included in this study; 350 podoconiosis patients and 350 healthy neighbourhood controls. The prevalence of TT was higher among podoconiosis patients than controls (65 (18.6% vs 43 (12.3% with an adjusted odds ratio OR 1.57 (95% CI 1.02-2.40, p = 0.04. There was no significant difference in prevalence of cataract between the two populations with an adjusted OR 0.83 (95% CI 0.55-1.25, p = 0.36. Mean best visual acuity was 0.59 (SD 0.06 in podoconiosis cases compared to 0.44 (SD 0.04 in controls, p<0.001.

    Knowledge on the factors associated with severe maternal morbidity enables a better understanding of the problem and serves as a foundation for the development of an effective preventive strategy. However, various definitions of severe maternal morbidity have been applied, leading to inconsistencies between studies. The objective of this study was to identify the sociodemographic characteristics, medical and gynaecological history, past and present obstetric performance and the provision of health care services as associated factors for severe maternal morbidity in Kelantan, Malaysia. A comparative cross-sectional study was conducted in two tertiary referral hospitals in 2014. Postpartum women with severe morbidity and without severe morbidity who fulfilled the inclusion and exclusion criteria were eligible as cases and controls, respectively. The study population included all postpartum women regardless of their age. Pregnancy at less than 22 weeks of gestation, more than 42 days after the termination of pregnancy and non-Malaysian citizens were excluded. Consecutive sampling was applied for the selection of cases and for each case identified, one unmatched control from the same hospital was selected using computer-based simple random sampling. Simple and multiple logistic regressions were performed using Stata Intercooled version 11.0. A total of 23,422 pregnant women were admitted to these hospitals in 2014 and 395 women with severe maternal morbidity were identified, of which 353 were eligible as cases. An age of 35 or more years old [Adj. OR (95 % CI): 2.6 (1.67, 4.07)], women with past pregnancy complications [Adj. OR (95 % CI): 1.7 (1.00, 2.79)], underwent caesarean section deliveries [Adj. OR (95 % CI): 6.8 (4.68, 10.01)], preterm delivery [Adj. OR (95 % CI): 3.4 (1.87, 6.32)] and referral to tertiary centres [Adj. OR (95 % CI): 2.7 (1.87, 3.97)] were significant associated factors for severe maternal morbidity. Our study suggests the enhanced

    This study of the developing pongid dentition is based on cross-sectional radiographic data of juvenile Pan troglodytes, Gorilla gorilla, and Pongo pygmaeus skulls. Comparisons with developmental features of the human dentition are made, and possible explanations for the formation of larger teeth within the reduced pongid growth period are discussed. The data presented in this study provide an alternative method for ageing individual pongid crania in comparative cross-sectional growth studies. The advantages of this method are demonstrated by ageing individual Gorilla crania form radiographs and plotting relative dental age against length of the jaw.

    Full Text Available OBJECTIVE: Here, we describe our experience with different therapeutic modalities used to treat cystic lymphangiomas in children in our hospital, including single therapy with OK-432, bleomycin and surgery, and a combination of the three modalities. METHODS: We performed a retrospective, cross-sectional study including patients treated from 1998 to 2011. The effects on macrocystic lymphangiomas and adverse reactions were evaluated. Twenty-nine children with cystic lymphangiomas without any previous treatment were included. Under general anesthesia, patients given sclerosing agents underwent puncture of the lesion (guided by ultrasound when necessary and complete aspiration of the intralesional liquid. The patients were evaluated with ultrasound and clinical examinations for a maximum follow-up time of 4 years. RESULTS: The proportions of patients considered cured after the first therapeutic approach were 44% in the surgery group, 29% in the bleomycin group and 31% in the OK-432 group. These proportions were not significantly different. Sequential treatment increased the rates of curative results to 71%, 74% and 44%, respectively, after the final treatment, which in our case was approximately 1.5 applications per patient. CONCLUSION: The results of this study indicate that most patients with cystic lymphangiomas do not show complete resolution after the initial therapy, regardless of whether the therapy is surgical or involves the use of sclerosing agents. To achieve complete resolution of the lesions, either multiple operations or a combination of surgery and sclerotherapy must be used and should be tailored to the characteristics of each patient.

    Values of generation Y nurses compared to generation X and baby boomers - A cross-sectional study Abstract. Several studies point to special behaviours of generation Y employees. Starting from the assumption that there is an effect on the attitudes and behaviour of values, the study deals with the question of differences in the values between generation Y (1981 - 1995) and generations X (1966 - 1980) and the baby boomers (1956 - 1965). Values are identified by nurses (n = 421) in the self-assessment as well as by stranger estimations of station leads (n = 259) and nursing directors (n = 312) in a quantitative cross-sectional study based on the PVQ-21 questionnaire was laid. While the values of self-centredness, stimulation, and hedonism are of high importance to generation Y in both self-assessment and outside consideration, tradition, conformity, and safety are considered less important. Likewise, for some values of generation Y, differences in self and other views can be determined. In the sense of a transformational understanding of leadership, operative and strategic nursing management must consider generation-specific differences in dealing with nursing staff.

    During pregnancy, a number of changes occur in women's body, and some medications are safe and some are not. The aim of our study was to establish the possible correlation between use of beta-lactam antibiotics in pregnancy and occurrence of congenital malformations. The study included 893 pregnant women from Zagreb and 6099 pregnant women from Novi Sad. 527 pregnant women used beta-lactams. First part of the study (one month study) was performed at four maternity hospitals in Zagreb, Croatia. Second part were collected as a part of the study analysing the teratogenicity of drugs used in pregnancy, a longitudinal study performed in Novi Sad district. Pregnant women most frequently used antibacterial agents in the first trimester of pregnancy. They used 15 different antibacterial medications, most often beta-lactams. In Zagreb arm, out of the total number of pregnant women that used medications during pregnancy (859), 231 (26.9%) used beta-lactam antibiotics. Malformations were detected in 8 (3.5%) cases. The prevalence of malformations in newborns whose mothers did not take beta-lactam antibiotics in pregnancy (662) was 2.7% (18 newborns with malformations). In Novi Sad arm, out of the total number of pregnant women that used medications during pregnancy (2013), 296 (14.7%) used beta-lactam antibiotics. Malformations were detected in 14 (4.7%) cases. The prevalence of malformations in newborns whose mothers did not take beta-lactam antibiotics in pregnancy (5803) was 1.7% (99 newborns with malformations). The results show possible teratogenic potential even with those antibacterials which are considered safe (amoxicillin) but as those are usually minor malformations they often pass undetected. International pharmacoepidemiological studies of drug use in pregnancy could substantially contribute to the improvement of pharmacotherapy, and could be of great help in assessing the fetal risks.

    To observe inpatient satisfaction at different public sector hospitals of Karachi, Pakistan. A cross sectional study was carried out during 2010-2012 in four major public sector hospitals of Karachi. A total of 710 patients completed the study. Responses were gathered in a self-structured questionnaire that comprised of four dimensions of satisfaction with doctor, staff, administration and treatment. Average Score of each dimension was taken and compared using one way analysis of variance. Satisfaction with doctors, staff and administration of provincial and federal hospitals were comparatively similar (P > 0.05). However, satisfaction with treatment significantly differed in all four hospitals (P public sector hospitals showed satisfaction with healthcare personnel and related administration. However, treatment dimension needs to be improved to get more satisfaction.

    Critical parameters were calculated using the one dimensional multigroup transport theory for several cross section sets. Calculations have been performed for water mixtures of uranium metal, plutonium metal and uranium-thorium oxide, and for metallics systems, to determine the critical dimensions of geometries (sphere and cylinder). For this aim, the following cross section sets were employed: 1) multigroup cross section sets obtained from the GAMTEC-II code; 2) the HANSEN-ROACH cross section sets; 3) cross section sets from the ENDF/B-IV, processed by the NJOY code. Finally, we have also calculated the corresponding critical radius using the one dimensional multigroup transport DTF-IV code. The numerical results agree within a few percent with the critical values obtained in the literature (where the greatest discrepancy occured in the critical dimensions of water mixtures calculated with the values generated by the NJOY code), a very good results in comparison with similar works.

    BACKGROUND: Although multimorbidity has important implications for patient care in general practice, limited research has examined chronic illness and health service utilisation among problem drug users. This study aimed to determine chronic illness prevalence and health service utilisation among problem drug users attending primary care for methadone treatment, to compare these rates with matched \\'controls\\' and to develop and pilot test a valid study instrument. METHODS: A cross-sectional study of patients attending three large urban general practices in Dublin, Ireland for methadone treatment was conducted, and this sample was compared with a control group matched by practice, age, gender and General Medical Services (GMS) status. RESULTS: Data were collected on 114 patients. Fifty-seven patients were on methadone treatment, of whom 52(91%) had at least one chronic illness (other then substance use) and 39(68%) were prescribed at least one regular medication. Frequent utilisation of primary care services and secondary care services in the previous six months was observed among patients on methadone treatment and controls, although the former had significantly higher chronic illness prevalence and primary care contact rates. The study instrument facilitated data collection that was feasible and with minimal inter-observer variation. CONCLUSION: Multimorbidity is common among problem drug users attending general practice for methadone treatment. Primary care may therefore have an important role in primary and secondary prevention of chronic illnesses among this population. This study offers a feasible study instrument for further work on this issue. (238 words).

    In this study, we compared the prevalence of psychiatric disorders and the characteristics of those who either use or do not use faith healers (FHs) services. We also assessed the independent factors of study subjects associated with using FHs. This cross-sectional study compared those who use FHs (n = 383) with a control group of those who do not use them (i.e., shopping mall visitors, n = 424) using a survey of sociodemographic characteristics and a validated Arabic version of the Mini International Neuropsychiatric Interview (MINI 6.0). Participants who ranked higher among FH users included males, people who were either married, divorced, or widowed, those with less education, and those with lower income. They were more likely to report past medical and psychiatric history. Those with diagnosable psychiatric disorders were more likely to visit FHs, especially if the diagnosis was of psychotic and bipolar disorders. The prevalence of psychiatric disorders was higher among FH users, and depressive and anxiety disorders were the most prevalent. The study showed that having past psychiatric history and a current psychiatric disorder are risk factors for using FHs. Also, a high percentage of FH users had a diagnosable psychiatric disorder. Further research should assess how to facilitate their access to the mental health system.

    Full Text Available The purpose of the study was to investigate the influence of human papillomavirus (HPV vaccination on adolescent girls' knowledge of HPV and HPV vaccine, perception of sexual risk and intentions for sexual debut. This cross-sectional comparative study was conducted in Ibanda and Mbarara districts. Data was collected using a standardized self-administered questionnaire and analyzed using the Statistical Package for the Social Sciences computer software. Univariate, bivariate, and logistic regression analyses were conducted with significance level set at p < .05. Results showed that HPV vaccination was associated with being knowledgeable (Crude OR: 5.26, CI: 2.32-11.93; p = 0.000. Vaccination against HPV did not predict perception of sexual risk. Knowledge was low (only 87/385 or 22.6% of vaccinated girls were knowledgeable, but predicted perception of a high sexual risk (Adjusted OR: 3.12, CI: 1.37-3.63; p = 0.008. HPV vaccination, knowledge and perceived sexual risk did not predict sexual behaviour intentions. High parental communication was associated with adolescent attitudes that support postponement of sexual debut in both bivariate and multiple regression analyses. In conclusion, findings of this study suggest that HPV vaccination is not likely to encourage adolescent sexual activity. Influence of knowledge on sexual behaviour intentions was not definitively explained. Prospective cohort studies were proposed to address the emerging questions.

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

    The overall prevalence of HBV in Ethiopia varies from 4.7-16.8% for Hepatitis B surface antigen (HBsAg) and 70-76.38% for at least one marker positive. Patients suffering from type I Diabetes Mellitus (DM) incur high risk of infection with hepatotropic viruses because of frequent hospitalization and blood tests. A comparative cross sectional study was conducted at Woldiya General Hospital using 108 consented study populations from Diabetes and 108 non diabetes control groups during the period November 2010 - January 2011. VISITECT HBsAg rapid test kit and Humastat 80 chemistry analyzer were used. Multivariate logistic regression was used to see the association of HBV with clinical history of participants and Sociodemographic variables. All tests were two-sided with α-level of 0.05 and 80% power. Prevalence of HBsAg was equal between diabetic and non diabetic individuals, 3.7% indicating that there was no difference between the two groups. Only history of invasive procedures and chronic liver disease showed association with HBsAg seropositivity. In this study a positive relation was not indicated between HBV and Diabetes and the prevalence of HBsAg was equal between diabetic and non diabetic individuals.

    Full Text Available Abstract Background Ethiopia is one of the most densely populated countries in Africa with an estimated population of 77.1 million in mid-2007. Uncontrolled fertility has adversely influenced the socio-economic, demographic and environmental situations of the country. It is one of the largest and poorest countries that, even in the midst of crisis, has maintained high levels of fertility. This study was aimed at investigating the most important factors influencing fertility behavior in Northwest Ethiopia. Methods A comparative cross-sectional study which included 2424 women aged 25 years and above was undertaken in the Amhara region of Northwest Ethiopia. The study subjects were grouped into high fertile and low fertile categories. There were 1011 and 1413 women in the high and low fertile groups, respectively. A multi-stage cluster sampling stratified by place of residence was employed to select the required study subjects. Both bivariate and multivariate logistic regression techniques were used to analyze the data. Results Among the 25 variables considered in this study, only 9 of them were found significantly and independently associated with the level of fertility. Women with at least secondary education were at a lower risk of high fertility with OR = 0.37 (95% CI: 0.21 to 0.64 compared to those with no formal education. However, women with primary education did not show any significant difference when compared with the same baseline group. Age at first marriage was inversely associated with the number of children ever born alive. Place of residence, household expenditure, number of children who have died, attitude towards using contraceptives, women's knowledge on the safe period, and current marital status were the other variables that showed significant associations with the level of fertility. Conclusion Female education beyond the primary level, reduced infant and child mortality, delayed marriage and correct knowledge on the safe

    Most young carer studies on parentification, resilience and coping concentrated on child carers up to age 18 years, whereas the group of young adult caregivers (18-24 years) has been neglected. In our study, we focused on these young adult caregivers, who are in a life phase in which young people usually are distancing themselves from their families and are striving for autonomy and freedom. To explore young adult carers' perceptions of parentification, resilience and coping compared to young adult noncarers. Cross-sectional. In 2014/2015, data were collected on 297 healthcare students from a school for vocational education and a university in the Netherlands. A fully structured questionnaire was used. Young adult carers were compared with young adult noncarers on parentification, resilience and coping. Fifty-six students identified themselves as a carer: 40 vocational education students and 16 university students. Carers scored significantly higher than noncarers on three out of six parentification dimensions. No differences were found for resilience and problem-focused coping behaviour, whereas results for emotion-focused coping demonstrated a higher score for the carers compared to the noncarers. Although it is important to take care of the needs of all young carers, special attention should be given to those who are at the start of their adult lives, undergoing extensive changes and taking major decisions on study and career issues. Home-care professionals and school counsellors should be able to recognise this group and their needs and activate support from specialised services and significant others. © 2018 The Authors.

    Hand washing is considered as one of the most effective hygiene promotion activities for public health in developing countries. This study compared hand washing knowledge and practices in BRAC's water; sanitation and hygiene (WASH) programme areas over time. This study is a cross-sectional comparative study between baseline (2006), midline (2009) and end-line (2011) surveys in 50 sub-districts from the first phase of the programme. Thirty thousand households from 50 sub-districts were selected in two steps: i) 30 villages were selected from each sub-district by cluster sampling, and ii) 20 households were chosen systematically from each village. The matched households were considered (26,404 in each survey) for analysis. Data were collected from households through face-to-face interview using a pre-tested questionnaire. Respondents were the adult female members of the same households, who had knowledge of day-to-day household activities related to water, sanitation and hygiene. A gap between perception and practice of proper hand washing practices with soap was identified in the study areas. Hand washing practice with soap before eating was much lower than after defecation. In baseline data, 8% reported to wash their hands with soap which significantly increased to 22% in end line. Hand washing knowledge and practices before cooking food, before serving food and while handling babies is considerably limited than other critical times. A multivariate analysis shows that socio-economic factors including education of household head and respondent, water availability and access to media have strong positive association with hand washing with soap. Gap between knowledge and practice still persists in hand washing practices. Long term and extensive initiatives can aware people about the effectiveness of hand washing.

    Full Text Available Abstract Background Quality of life differs for different people in different situations and is related to one's self-satisfaction with life. Considering the role of women in family and social health and the specific cultural characteristics of our province, we aimed to compare the quality of life of employed women with housewives in Zahedan, Iran. Methods This cross-sectional study was carried out during 2009–2010 in Zahedan, Iran. The sample consisted of 110 housewives and 110 employed women selected randomly from ten health care centers. Health-related quality of life was assessed using the SF-36. Analysis of covariance (ANCOVA was used to compare quality of life in housewives and employed women while controlling for age, education and income. Results The mean (±SD age of participants was 33.87± 8.95 years. Eighty-eight women (40% had a university degree with a mean (±SD official education of 10.8 (±4.9 years. The results indicated that employed women scored higher than housewives in all measures except for physical functioning. The differences were found to be remarkable for vitality, mental health and role emotional. However, after controlling for age, education and family income, none of differences reached significant level. Conclusion After controlling for potential confounders, the findings from this study indicated that there were no significant differences in quality of life between employed women and housewives. However, employed women scored higher on the SF-36, especially on the role emotional, vitality, and mental health. The findings suggest that associations exist between some aspects of health-related quality of life and employment. Indeed improving health-related quality of life among housewives seems essential.

    People with severe mental disorders are associated with increased risk of suicide and suicide attempts compared to the general population. In low and middle-income countries, research concerning suicide attempts and completed suicide among people living with severe mental disorder is limited. The objective of this study was to assess suicide and attempts in people with severe mental disorder at Amanuel Mental Specialized Hospital, Addis Ababa, Ethiopia. Institution-based cross-sectional study was conducted in August-September 2016. Patients with schizophrenia and bipolar disorder were selected using systematic random-sampling technique. The composite international diagnostic interview was used to assess suicide that was administered by psychiatry professionals. Substance use disorder was assessed through face-to-face interviews using structured clinical interview of DSM-IV. A total of 542 (272 schizophrenia + 270 bipolar disorder) patients were included in the study. One hundred nineteen (43.75%) of schizophrenic participants and 128 (47.1%) of bipolar participants have suicidal ideation. Fifty-six (20.7%) of schizophrenic participants and 58 (21.3%) of bipolar participants have suicidal attempt. Among the schizophrenic and bipolar patients who had suicidal ideation, 31.8 and 32.60% had co-morbid substance use disorder, respectively. In this study, which was performed in Ethiopia, suicidal ideation and attempt were shown to be common problems in people with schizophrenia and bipolar disorder. Co-morbid substance use disorder was a more frequent phenomenon among patients with suicidal ideation and attempt. Attention should be given to screen and assess suicidal ideation and attempt in persons with schizophrenia and bipolar disorder.

    Full Text Available AIM: To present a method of screening for irregular astigmatism with an autorefractor and its determinants compared to corneal topography. METHODS: This cross-sectional validity study was conducted in 2013 at an eye hospital in Spain. A tabletop autorefractor (test 1 was used to measure the refractive status of the anterior surface of the cornea at two corneal meridians of each eye. Then corneal topography (test 2 and Bogan’s classification was used to group eyes into those with regular or no astigmatism (GRI and irregular astigmatism (GRII. Test 1 provided a single absolute value for the greatest cylinder difference (Vr. The receiver operating characteristic (ROC were plotted for the Vr values measured by test 1 for GRI and GRII eyes. On the basis a Vr value of 1.25 D as cut off, sensitivity, specificity were also calculated. RESULTS: The study sample was comprised of 260 eyes (135 patients. The prevalence of irregular astigmatism was 42% [95% confidence interval (CI: 36, 48]. Based on test 2, there were 151 eyes in GRI and 109 eyes in GRII. The median Vr was 0.75 D (25% quartile, 0.5 D for GRI and 1.75 D (25% quartile, 1.25 D for GRII. The area under curve was 0.171 for GRI and 0.83 for GRII. The sensitivity of test I was 78.1% and the specificity was 76.1%. CONCLUSION: A conventional autorefractor can be effective as a first level screening method to detect irregular corneal astigmatism in places where corneal topography facilities are not available.

    People with stroke have reduced walking activity. It is not known whether this deficit is due to a reduction in all aspects of walking activity or only in specific areas. Understanding specific walking activity deficits is necessary for the development of interventions that maximize improvements in activity after stroke. The purpose of this study was to examine walking activity in people poststroke compared with older adults without disability. A cross-sectional study was conducted. Fifty-four participants poststroke and 18 older adults without disability wore a step activity monitor for 3 days. The descriptors of walking activity calculated included steps per day (SPD), bouts per day (BPD), steps per bout (SPB), total time walking per day (TTW), percentage of time walking per day (PTW), and frequency of short, medium, and long walking bouts. Individuals classified as household and limited community ambulators (n=29) did not differ on any measure and were grouped (HHA-LCA group) for comparison with unlimited community ambulators (UCA group) (n=22) and with older adults without disability (n=14). The SPD, TTW, PTW, and BPD measurements were greatest in older adults and lowest in the HHA-LCA group. Seventy-two percent to 74% of all walking bouts were short, and this finding did not differ across groups. Walking in all categories (short, medium, and long) was lowest in the HHA-LCA group, greater in the UCA group, and greatest in older adults without disability. Three days of walking activity were captured. The specific descriptors of walking activity presented provide insight into walking deficits after stroke that cannot be ascertained by looking at steps per day alone. The deficits that were revealed could be addressed through appropriate exercise prescription, underscoring the need to analyze the structure of walking activity.

    Opposition to human papillomavirus (HPV) vaccination is common on social media and has the potential to impact vaccine coverage. This study aims to conduct an international comparison of the proportions of tweets about HPV vaccines that express concerns, the types of concerns expressed and the social connections among users posting about HPV vaccines in Australia, Canada and the UK. Using a cross-sectional design, an international comparison of English language tweets about HPV vaccines and social connections among Twitter users posting about HPV vaccines between January 2014 and April 2016 was conducted. The Health Belief Model, one of the most widely used theories in health psychology, was used as the basis for coding the types of HPV vaccine concerns expressed on Twitter. The content of tweets and the social connections between users who posted tweets about HPV vaccines from Australia, Canada and the UK. 16 789 Twitter users who posted 43 852 tweets about HPV vaccines. The proportions of tweets expressing concern, the type of concern expressed and the proportions of local and international social connections between users. Tweets expressing concerns about HPV vaccines made up 14.9% of tweets in Canada, 19.4% in Australia and 22.6% in the UK. The types of concerns expressed were similar across the three countries, with concerns related to 'perceived barriers' being the most common. Users expressing concerns about HPV vaccines in each of the three countries had a relatively high proportion of international followers also expressing concerns. The proportions and types of HPV vaccine concerns expressed on Twitter were similar across the three countries. Twitter users who mostly expressed concerns about HPV vaccines were better connected to international users who shared their concerns compared with users who did not express concerns about HPV vaccines. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Gastro-esophageal reflux disease (GERD) is suggested to be associated with some socio-demographic and lifestyle factors. Although the roles of some factors such as obesity are well documented, evidence on the impact of other factors such as dietary habits are still inconclusive. The aim of this study was to determine the relationship between socio-demographic and lifestyle factors with GERD in participants referred to a teaching hospital in Zahedan, South-East of Iran. This comparative cross-sectional study was conducted during 2014-2015. All patients completed a structured questionnaire regarding information on socio-demographic status, lifestyle factors and dietary habits. Anthropometric indices including body mass index (BMI) and waist circumference (WC) were used to determine general and central obesity, respectively. Data were analyzed using SPSS software version 22. Value of p obesity (OR = 1.77, 95%CI = 1.11, 2.81), central obesity (OR = 2.09, 95%CI = 1.46,3.01) and consumption of citrus fruits between meals (OR = 1.69, 95%CI = 1.04, 2.73) were associated with higher odds of GERD, while higher educational level (OR = 0.53, 95%CI = 0.36,0.77) and regular physical activity ≥2 h/week (OR = 0.53, 95%CI = 0.30, 0.94) were associated with lower odds of GERD. In the adjusted model, central obesity (OR = 1.88, 95%CI = 1.18, 3.01) and consumption of citrus fruits between meals (OR = 2.22, 95%CI = 1.30, 3.81) were positively associated with odds of GERD, while higher educational level (OR = 0.55, 95%CI = 0.33, 0.91) was associated with decreased odds of GERD. According to the results of the current study, central obesity as determined by WC and citrus fruit intake were independent factors associated with GERD. Therefore, lifestyle modification might have a positive effect in the treatment of GERD in an urban population of Iran.

    To assess the relation between male and female medical leadership. Cross sectional study on predictive factors for female medical leadership with data on sex, age, specialty, and occupational status of Norwegian physicians. Oslo, Norway. 13 844 non-retired Norwegian physicians. Medical leaders, defined as physicians holding a leading position in hospital medicine, public health, academic medicine, or private health care. 14.6% (95% confidence interval 14.0% to 15.4%) of the men were leaders compared with 5.1% (4.4% to 5.9%) of the women. Adjusted for age men had a higher estimated probability of leadership in all categories of age and job, the highest being in academic medicine with 0.57 (0.42 to 0.72) for men aged over 54 years compared with 0.39 (0.21 to 0.63) for women in the same category. Among female hospital physicians there was a positive relation between the proportion of women in their specialty and the probability of leadership. Women do not reach senior positions as easily as men. Medical specialties with high proportions of women have more female leaders.

    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.

    Cardiovascular disease is the leading cause of adult mortality in India but data on the prevalence of cardiovascular risk factors are scarce, especially from North-east region of India. This study aims to assess the prevalence and the urban/tribal gradient of cardiovascular disease risk factors among healthy population of Tripura. A cross-sectional study was carried out among 238 healthy individuals (140 urban and 98 tribal) in one urban and five tribal areas of Tripura. Data was collected on sociodemographic profile, medical history, anthropometry, dietary patterns and addiction. Fasting blood samples were collected for biochemical analysis. Prevalence of cardiovascular disease risk factors and short-term cardiovascular disease risk score was calculated. The association of independent variables with 10-year cardiovascular disease risk score were examined by using multiple regression model. Prevalence of obesity, hypertension, diabetes, dyslipidaemia, metabolic syndrome and short-term cardiovascular disease risk score were higher in urban group. Urban people had higher salt, calories and fat intake. No difference was found in the addiction patterns of tobacco and alcohol but frequency and quantity being higher in tribal area. Dyslipidaemia and alcohol consumption showed significant positive association with 10-year cardiovascular disease risk score in both groups. While the non-sedentary lifestyle and dietary habits (low salt, low fat, carbohydrate predominant) of tribal population need to be promoted as a whole across the nation, they need to be protected from the adverse effects of rampant prevalence of tobacco and alcohol addiction among them. Urban population need to be extricated from adverse effects of sedentary lifestyle, modern food habits (high salt, high fat) and tobacco-alcohol addiction.

    This study investigates current opinions about hospital advertising and compares them to the attitudes expressed 25 years ago. It replicates a survey done in 1985, using the same questionnaire and population to compare responses longitudinally. The study indicates some changes in the public's opinions of hospital advertising. Although the image of hospitals remains positive, most of the 2010 respondents' opinions were rather mixed regarding whether it is proper for hospitals to advertise. The study also confirmed that the quality of service and reputation of hospitals remain more important to the public than price.

    The purpose of this study is to investigate current attitudes and opinions of physicians' advertising and to compare them to the attitudes expressed 10 years previously. This study was designed to determine (a) consumers' attitudes toward advertising by physicians, and (b) whether age, occupation, income, education, or sex of consumer accounted for any significant difference in attitudes toward physicians who advertise. The study seems to confirm the belief of many marketing professionals that advertising and marketing do not have a place in the management and operation of professional services.

    Alteration in peripheral iron indices has been reported in a number of movement disorders, particularly Parkinson's disease. We hypothesized that iron stores may be diminished in children at an early stage of tic disorder. Using data retrieved from electronic medical records, we compared serum ferritin levels, an indicator of body iron store balance, in drug-naive children diagnosed for the first time with tic disorder (study group; N = 47, 32 boys/15 girls, aged 8.66 ± 3.17 years) compared to age- and sex-matched children with headaches (comparison group, n = 100, 62 boys/38 girls, aged 9.51 ± 3.15 years) treated in the same pediatric neurological clinic. Mean serum ferritin levels were significantly lower (-32%, p = 0.01) in the tic disorder group compared to the headache group. No significant differences were detected in circulatory hemoglobin, iron, transferrin, and platelet count between the two groups. Our findings suggest that body iron stores may be reduced in children with recent-onset tic disorder.

    Stress and distress among medical students are thoroughly studied and presumed to be particularly high, but comparative studies including other student groups are rare. A web-based survey was distributed to 500 medical students and 500 business students. We compared levels of study stress (HESI), burnout (OLBI), alcohol habits (AUDIT) and depression (MDI), and analysed their relationship with self-assessed mental health problems by logistic regression, with respect to gender. Medical students' response rate was 81.6% and that of business students 69.4%. Business students scored higher on several study stress factors and on disengagement. Depression (OR 0.61, CI95 0.37;0.98) and harmful alcohol use (OR 0.55, CI95 0.37; 0.75) were both less common among medical students. However, harmful alcohol use was highly prevalent among male students in both groups (medical students 28.0%, business students 35.4%), and among female business students (25.0%). Mental health problems in need of treatment were equally common in both groups; 22.1% and 19.3%, respectively, and was associated with female sex (OR 2.01, CI95 1.32;3.04), exhaustion (OR 2.56, CI95 1.60;4.10), lower commitment to studies (OR 1.95, CI95 1.09;3.51) and financial concerns (OR 1.81 CI95 1.18;2.80) Medical students may not be more stressed than other high achieving student populations. The more cohesive structure of medical school and a higher awareness of a healthy lifestyle may be beneficial factors.

    Previous research shows an association between obesity and attention deficit hyperactivity disorder (ADHD). The present study compares pre- and post-bariatric surgery patients using the internationally used Conners' Adult ADHD Rating Scale (CAARS™) to screen for ADHD. Matched samples pre- (N = 120) and post-bariatric surgery (N = 128) were compared using self-rating instruments to assess ADHD-relevant symptomatology, depression, eating-related psychopathology, and BMI. Prevalence of probable ADHD did not differ between groups using the CAARS Index Scale T-scores; however, CAARS subscales Inattention/Memory and Self-Concept showed significantly lower scores in post-surgery patients. All CAARS subscales correlated significantly with each other, with depression and eating-related psychopathology. There was no correlation between ADHD and excess BMI loss in post-surgery patients. The findings suggest that a considerable number of patients before and after bariatric surgery screened positive for ADHD. It can be hypothesized that some core ADHD symptoms improve after surgery. Future studies are warranted to investigate the influence of ADHD on long-term surgery outcomes. © 2017 The Author(s) Published by S. Karger GmbH, Freiburg.

    Full Text Available Abstract Background Health is vital to a child's learning in school and success in life. Therefore, early physical examination, and follow-up if necessary, would bring parents' attention to their child's health and would likely improve outcomes. The purposes of this study are twofold: to assess the health status of first-graders and to examine the health status differences between sexes, levels of residence urbanization, and quantity of available medical resources. Methods This is a comparative descriptive study. Data from the 2002 Student Entry Physical Examination (SEPE and Student Medical History Inventory (SMHI were obtained from 203 public and private elementary schools in northern Taiwan where a population of 53,053 students was included. Frequencies, independent sample t test, one-way ANOVA along with Scheff's post hoc test, and Pearson's correlation were conducted using SPSS. Results This study showed that 13.7% of students had at least one diagnosed disease from the SMHI reported by parents. Moreover, the SEPE indicated that 79.5% students had at least one health concern. Dental caries, myopia, and obesity were the most prevalent health problems among the first-graders (69.6%, 27.1%, and 9.5%, respectively. Research results show that there were significant differences in the prevalence of dental caries, myopia, and obesity between different sexes and among levels of urbanization. However, the quantity of available medical resources made no significant difference. Conclusion Elementary school entry physical examination is an important way to detect students' health problems. It is suggested that school health interventions consider students' health profiles along with their sex and level of urbanization in planning. More research is needed to find the risk factors of the health problems. Additionally, the creation of a school health committee is suggested to implement and evaluate the entry health examination program.

    Full Text Available Loss of traditional diets by food globalization may have adverse impact on the health of human being through the alteration of gut microbial ecosystem. To address this notion, we compared the gut microbiota of urban (n = 17 and rural (n = 28 school-aged children in Thailand in association with their dietary habits. Dietary records indicated that children living in urban Bangkok tended to consume modern high-fat diets, whereas children in rural Buriram tended to consume traditional vegetable-based diets. Sequencing of 16S rRNA genes amplified from stool samples showed that children in Bangkok have less Clostridiales and more Bacteroidales and Selenomonadales compared to children in Buriram and bacterial diversity is significantly less in Bangkok children than in Buriram children. In addition, fecal butyrate and propionate levels decreased in Bangkok children in association with changes in their gut microbial communities. Stool samples of these Thai children were classified into five metabolotypes (MTs based on their metabolome profiles, each characterized by high concentrations of short and middle chain fatty acids (MT1, n = 17, amino acids (MT2, n = 7, arginine (MT3, n = 6, amino acids, and amines (MT5, n = 8, or an overall low level of metabolites (MT4, n = 4. MT1 and MT4 mainly consisted of samples from Buriram, and MT2 and MT3 mainly consisted of samples from Bangkok, whereas MT5 contained three samples from Bangkok and five from Buriram samples. According to the profiles of microbiota and diets, MT1 and MT2 are characteristic of children in Buriram and Bangkok, respectively. Predicted metagenomics indicated the underrepresentation in MT2 of eight genes involved in pathways of butyrate biosynthesis, notably including paths from glutamate as well as pyruvate. Taken together, this study shows the benefit of high-vegetable Thai traditional diets on gut microbiota and suggests that high-fat and less-vegetable urban dietary habits alter gut

    Missing posterior teeth can decrease masticatory function and cause horizontal mastication deviation, i.e., mastication predominance. Mastication predominance may lead to abnormal tooth attrition and temporomandibular disorders. This study evaluated masticatory performance and mastication predominance in patients with missing posterior teeth to investigate effects of missing posterior teeth on masticatory performance and mastication predominance. Thirty volunteers with normal dentition (control group), 30 patients with unilateral missing posterior teeth (unilateral group), and 23 patients with bilateral missing posterior teeth (bilateral group) participated. Gummy jellies were used to evaluate participants' masticatory performance, and electromyography was used to assess the degree of mastication predominance. Chewing gums, gummy jellies, and peanuts were used as foods of various hardnesses for evaluating mastication predominance. Compared with the control group, masticatory performance did not differ in the unilateral group but was significantly decreased in the bilateral group. With chewing gum and gummy jellies, the degree of mastication predominance was significantly increased in both unilateral and bilateral groups than the control group. With peanuts, the degree of mastication predominance was significantly increased in the unilateral group than the control group. Although masticatory performance was not decreased in the unilateral group, the degree of mastication predominance was increased. Decreased masticatory performance was observed in the bilateral group, and for foods with normal hardness and soft foods, the degree of mastication predominance was increased. These results suggested that mastication predominance should be considered in the recovery of masticatory performance in patients with missing posterior teeth.

    The purpose of this study was to explore and compare foot and ankle characteristics in people with stroke and healthy controls; and between stroke fallers and non-fallers. Participants were recruited from community groups and completed standardized tests assessing sensation, foot posture, foot function, ankle dorsiflexion and first metatarsal phalangeal joint range of motion (1st MPJ ROM), hallux valgus presence and severity. Twenty-three stroke participants (mean age 75.09 ± 7.57 years; 12 fallers) and 16 controls (mean age 73.44 ± 8.35 years) took part. Within the stroke group, reduced 1st MPJ sensation (p = 0.016) and 1st MPJ ROM (p = 0.025) were observed in the affected foot in comparison to the non-affected foot; no other differences were apparent. Pooled data (for both feet) was used to explore between stroke/control (n = 78 feet) and stroke faller/non-faller (n = 46 feet) group differences. In comparison to the control group, stroke participants exhibited reduced sensation of the 1st MPJ (p = 0.020), higher Foot Posture Index scores (indicating greater foot pronation, p = 0.008) and reduced foot function (p = 0.003). Stroke fallers exhibited significantly greater foot pronation in comparison to non-fallers (p = 0.027). Results indicated differences in foot and ankle characteristics post stroke in comparison to healthy controls. These changes may negatively impact functional ability and the ability to preserve balance. Further research is warranted to explore the influence of foot problems on balance ability and falls in people with stroke. Implications for Rehabilitation Foot problems are common post stroke. As foot problems have been linked to increased fall risk among the general population we recommend that it would be beneficial to include foot and ankle assessments or a referral to a podiatrist for people with stroke who report foot problems. Further research is needed to explore if we can improve functional

    CT is a contemporary non-invasive imaging technique that gains an increasing importance for in vivo investigations of subcutaneous and visceral fat. The purpose of this investigation was to describe the topography and anatomy imaging features of perirenal fat depots at the level of both kidneys in clinically healthy New Zealand White rabbits that attained slaughter weight. The CT consecutive transverse scans from the last thoracic to the fifth lumbar vertebrae showed that in rabbits, perirenal fat appeared as a homogeneous hypodense structure at the background of denser shadows of lumbar and abdominal muscles, kidneys and abdominal organs. Perirenal fat depot exhibited a soft tissue density with average attenuation of −120.97±4.73 HU. On CT scans, the largest dimensions of the perirenal fat depot were 1.3±0.01 cm at the level of the right kidneys cranial pole; 1.96 cm in the plane where the right renal hilus was visualized; 1.66±0.08 cm at the level of the right kidneys caudal pole; 1.10±0.18 cm in the plane where the left renal hilus was visualized and 1.06±0.15 cm at the level of the left kidneys caudal pole. No subcutaneous fat deposits in the abdominal area were seen. Results obtained in the present study could be used as basic information for various anatomy investigations of rabbits as well as experimental designs for study of obesity in animals and humans.

Early interventions to prevent long-term sick-listing require the identification of patients at risk. The aim of this study was to compare living conditions associated with long-term sick-listing for NSP in patients with nonacute NSP, with a nonpatient population-based sample. Nonacute NSP is pain that leads to full-time sick-listing>3 weeks.Methods: One hundred and twenty-five patients with nonacute NSP, 2000–2004, were included in a randomized controlled trial in Stockholm County with the objective of comparing cognitive–behavioral rehabilitation with traditional primary care. For these patients, a cross-sectional study was carried out with baseline data. Living conditions were compared between the patients and 338 nonpatients by logistic regression. The conditions from univariate analyses were included in a multivariate analysis. The nonsignificant variables were excluded sequentially to yield a model comprising only the significant factors (P <0.05. The results are shown as odds ratios (OR with 95% confidence intervals.Results: In the univariate analyses, 13 of the 18 living conditions had higher odds for the patients with a dominance of physical work strains and Indication of alcohol over-consumption, odds ratio (OR 14.8 (95% confidence interval [CI] 3.2–67.6.

    Ultrasound-guided peripheral intravenous access may present an alternative to central or intraosseous access in patients with difficult peripheral veins. Using venepuncture of a phantom model as a proxy, we investigated whether novice ultrasound users should adopt a cross-sectional or longitudinal approach when learning to access peripheral veins under ultrasound guidance. This result would inform the development of a structured training method for this procedure. We conducted a randomised controlled trial of 30 medical students. Subjects received 35 min of training, then attempted to aspirate 1 ml of synthetic blood from a deep vein in a training model under ultrasound guidance. Subjects attempted both the cross-sectional and longitudinal approaches. Group 1 used cross-sectional first, followed by longitudinal. Group 2 used longitudinal first, then cross-sectional. We measured the time from first puncture of the model's skin to aspiration of fluid, and the number of attempts required. Subjects also reported difficulty ratings for each approach. Paired sample t-tests were used for statistical analysis. The mean number of attempts was 1.13 using the cross-sectional approach, compared with 1.30 using the longitudinal approach (p = 0.17). Mean time to aspiration of fluid was 45.1 s using the cross-sectional approach and 52.8 s using the longitudinal approach (p = 0.43). The mean difficulty score out of 10 was 3.97 for the cross-sectional approach and 3.93 for the longitudinal approach (p = 0.95). We found no significant difference in effectiveness between the cross-sectional and longitudinal approaches to ultrasound-guided venepuncture when performed on a model. We believe that both approaches should be included when teaching ultrasound-guided peripheral vascular access. To confirm which approach would be best in clinical practice, we advocate future testing of both approaches on patients.

    Acne is a multifactorial dermatosis, which is influenced not only by hormones but also by the biochemical relationship between them and the pilosebaceous unit. Inflammatory cytokines, chemokines, active oxygen, and zinc are known to be associated with the development of acne. Further, steroid metabolism is known as one of the important factors related to sebum secretion and comedone formation in acne. However, there is a lack of studies comparing these human biomarkers between healthy individuals and patients with acne. In particular, no study has investigated the relationship between human biomarkers and patterns of acne yet.The purpose of this study is to investigate diagnostic human biomarkers in acne by comparing the biological and metabolic biomarkers between healthy individuals and patients with acne and identify the relationship between human biomarkers and patterns of acne.This study is a protocol for a cross-sectional study. Forty healthy participants and 60 patients with acne will be recruited at 1 center. We will collect their blood samples and analyze the molecular biological and metabolic biomarkers (cytokines, chemokines, reactive oxygen species, corticotropin-releasing hormone, zinc, amino acid, 1-carbon metabolite, lipid metabolite, etc.). Further, we will administer questionnaires regarding their diet, sleep, stress, and other factors relating to acne and measure their skin elasticity.The study protocol was approved by the Institutional Review Board of Oriental Medical Hospital at Kyung Hee Medical Center (KOMCIRB-161118-HR-062). Written informed consent will be obtained from all the participants. The trial was registered in the Clinical Research Information Service, Republic of Korea: KCT0002212.This trial will provide evidence regarding diagnostic human biomarkers in acne and the relationship between the human biomarkers and patterns of acne.

    Because primary knock-on atoms (PKAs) create point defects and clusters in materials that are irradiated with neutrons, it is important to validate the calculations of recoil cross section spectra that are used to estimate radiation damage in materials. Here, the recoil cross section spectra of fission- and fusion-relevant materials were calculated using the Event Generator Mode (EGM) of the Particle and Heavy Ion Transport code System (PHITS) and also using the data processing code NJOY2012 with the nuclear data libraries TENDL2015, ENDF/BVII.1, and JEFF3.2. The heating number, which is the integral of the recoil cross section spectra, was also calculated using PHITS-EGM and compared with data extracted from the ACE files of TENDL2015, ENDF/BVII.1, and JENDL4.0. In general, only a small difference was found between the PKA spectra of PHITS + TENDL2015 and NJOY + TENDL2015. From analyzing the recoil cross section spectra extracted from the nuclear data libraries using NJOY2012, we found that the recoil cross section spectra were incorrect for {sup 72}Ge, {sup 75}As, {sup 89}Y, and {sup 109}Ag in the ENDF/B-VII.1 library, and for {sup 90}Zr and {sup 55}Mn in the JEFF3.2 library. From analyzing the heating number, we found that the data extracted from the ACE file of TENDL2015 for all nuclides were problematic in the neutron capture region because of incorrect data regarding the emitted gamma energy. However, PHITS + TENDL2015 can calculate PKA spectra and heating numbers correctly.

    Objective To assess and compare health system performance across six middle-income countries that are strengthening their health systems in pursuit of universal health coverage. Design Cross-sectional analysis from the World Health Organization Study on global AGEing and adult health, collected between 2007 and 2010. Setting Six middle-income countries: China, Ghana, India, Mexico, Russia and South Africa. Participants Nationally representative sample of adults aged 50 years and older. Main outcome measures We present achievement against key indicators of health system performance across effectiveness, cost, access, patient-centredness and equity domains. Results We found areas of poor performance in prevention and management of chronic conditions, such as hypertension control and cancer screening coverage. We also found that cost remains a barrier to healthcare access in spite of insurance schemes. Finally, we found evidence of disparities across many indicators, particularly in the effectiveness and patient centredness domains. Conclusions These findings identify important focus areas for action and shared learning as these countries move towards achieving universal health coverage.

    Lone parenthood is associated with poorer health; however, the vast majority of previous studies have examined lone mothers and only a few have focused on lone fathers. We aimed to examine the self-rated health and mental health status among a large population-based cross-sectional sample of Canadian lone fathers compared with both partnered fathers and lone mothers. We investigated differences in self-rated health and mental health among 1058 lone fathers compared with 20 692 partnered fathers and 5725 lone mothers using the Ontario component of the Canadian Community Health Survey (2001-2013). Multivariable logistic regression was used to compare the odds of poor/fair self-rated health and mental health between the study groups while adjusting for a comprehensive list of sociodemographic factors, stressors and lifestyle factors. Lone fathers and lone mothers showed similar prevalence of poor/fair self-rated health (11.6% and 12.5%, respectively) and mental health (6.2% and 8.4%, respectively); the odds were similar even after multivariable adjustment. Lone fathers showed higher odds of poor/fair self-rated health (OR 1.53, 95% CI 1.07 to 2.17) and mental health (OR 2.09, 95% CI 1.26 to 3.46) than partnered fathers after adjustment for sociodemographic factors; however, these differences were no longer significant after accounting for stressors, including low income and unemployment. In this large population-based study, lone fathers had worse self-rated health and mental health than partnered fathers and similarly poor self-rated health and mental health as lone mothers. Interventions, supports and social policies designed for single parents should also recognise the needs of lone fathers. Published by the BMJ Publishing Group Limited.

    Risky sexual behavior (RSB) and its consequence among school adolescents and youths have been well understood. It is still a common practice among college and university students living away from their controlling families compounded with the ever-worsening khat chewing habits. However, the relation between khat chewing and RSB is not well studied particularly among college students in Ethiopia. Hence, this study contributes to the literature by examining disparities of RSB among khat chewer and non-chewer students in Southern Ethiopia with the purpose of improving adolescent and youth health. An institution-based comparative cross-sectional study was conducted among 1211 college students at Arba Minch town in March 2015. Respondents were selected by employing a simple random sampling technique. Data was collected by using a pre-tested, structured, self- administered questionnaire. The data was entered into Epidata version 3.1 and analyzed using IBM SPSS statistics version 21. Level of statistical significance was declared at a p- value of pornographic movies (AOR = 2.51, 95% CI = 1.79,3.51), khat chewing (AOR = 3.02, 95% CI:=1.91,4.76) and alcohol drinking (AOR = 2.26, 95% CI = 1.54,3.35) were factors associated with RSB. Considerable proportions of students were engaged in khat chewing and RSB. RSB was significantly higher among khat chewers as compared to non- chewers. Comprehensive sexuality education was recommended to college communities and by extension to the ministry of health and education to address the identified factors so that RSB can be reshaped.

    Full Text Available Background: An association of eating disorder with diabetes mellitus may lead to a serious lack of metabolic control, higher mortality and morbidity. There is no recent study conducted in the Iranian population about eating disorder and its variants. The aim of the present study is investigation of frequency of disturbed eating behaviors in adolescent girls with type 1 diabetes mellitus (T1DM compared to non-diabetics. Materials and Methods: In this cross-sectional study, disturbed eating behavior were evaluated and compared in two groups of 12-22 year old adolescent and young females (126 with diabetes and 325 without diabetes. A self-report questionnaire including demographic data, Children′s Depression Inventory (CDI, and Eating Attitude Test (EAT-26 was used for data gathering. Independent t-test, Chi-square test, and logistic regression [odds ratio (OR] were used for data analyses in SPSS 15. Results: Findings revealed that higher percentage of diabetic girls are likely to have eating disturbances (67.9% vs. 53.8%, P = 0.01. Diabetic group obtained higher scores in both dieting (14.95 ± 6.28 vs. 11.79 ± 5.62, P < 0.001 and bulimia scales (4.9 ± 3.13 vs. 4.12 ± 2.89, P = 0.017, which supports a role for T1DM in inducing the symptoms. Diabetic girls were at more than double the risk of developing eating disturbance. Conclusions: The results indicate that a significantly higher percentage of diabetic girls are likely to have eating disturbances. Also, diabetic subjects had an increased probability of getting higher scores in all three EAT-26 subscales. Therefore, healthcare professionals, especially diabetic nurses, should be aware of the potential effects of the subclinical and clinical eating behaviors on adolescents with T1DM and evaluate them for these disturbances.

    Multicultural comparative studies have recently increased scientific knowledge base regarding the mental health of diverse populations. This cross-cultural study was cross-sectionally designed to assess differences in the prevalence and predictors of clinically significant depressive symptoms between Chinese and Malawian children. A total of 478 children (237 Chinese and 241 Malawians) were randomly recruited in the study. The participants completed a Children Depression Inventory in the dimensions of Negative Mood, Interpersonal Problems, Ineffectiveness, Anhedonia, and Negative Self- Esteem. They further provided demographic and family structure information. Data were analyzed by Student's t-test, Chi-square test, and logistic regression. The prevalence of clinically significant depressive symptoms was 16% and 12.4% for Chinese and Malawian study participants, respectively. Multivariate logistic regression analysis showed that fighting among siblings (adjusted odds ratio [aOR] = 4.1, 95% CI, 3.5-5.9), fighting among children and parents (aOR = 7.7, 95% CI, 4.6-9.8) and living with father only (aOR = 4.1, 95% CI, 3.4-6.7) were significant predictors of clinically significant depressive symptoms among Chinese study participants. On the other hand, clinically significant depressive symptoms were predicted by employment status of a mom only among Malawian study participants (aOR = 3.0, 95% CI, 2.3-5.9). We conclude that diverse cultures affect children's mental health differently and this cluster of children has a noticeable amount of depressive symptoms that in the least requires further diagnosis and preventive measures.

    Childhood obesity has more than doubled since it was formally recognized as a global epidemic in 1997. With increasingly dwindling space for private schools in Ethiopia, there is unresolved concern among the public on the possible effect of limited play area in schools on overweight/obesity. This study intended to determine and compare the levels of overweight and obesity among adolescents in private schools with and without adequate play area in Addis Ababa. School based comparative cross-sectional study was conducted among 1276 adolescents. 20 private schools were grouped into two based on their size of play area. Data were collected using a pre-tested questionnaire and anthropometric measurements and analyzed using descriptive statistical tests and logistic regression. The magnitude of overweight and obesity was significantly higher in schools without adequate play area than in schools with adequate play area, % (95% CI) = 19.4% (16.4 - 22.7%) and 14.6% (11.9 - 17.5%) respectively. Inadequate play area was also positively associated with overweight/obesity in the multiple logistic regression analysis, OR (95% CI) = 1.62 (1.05-2.51). Using private car transportation to and from school, father's educational status (secondary school and above) and middle wealth quintile were other significantly associated factors with overweight/obesity, OR (95% CI) =2.27 (1.13-4.57), 2.54 (1.14-5.62) and 2.54 (1.50-4.33) respectively. Inadequate play area in schools is an important contributor for overweight and obesity. Sedentary behavior was also significant factor associated with overweight/obesity.

    Subjective cognitive impairment can be a significant and prevalent problem for gynaecological cancer survivors. The aims of this study were to assess subjective cognitive functioning in gynaecological cancer survivors after primary cancer treatment, and to investigate the impact of cancer treatment on brain structural networks and its association with subjective cognitive impairment. This was a cross-sectional survey using a self-reported questionnaire by the Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog) to assess subjective cognitive functioning, and applying DTI (diffusion tensor imaging) and graph theoretical analyses to investigate brain structural networks after primary cancer treatment. A total of 158 patients with gynaecological cancer (mean age, 45.86 years) and 130 age-matched non-cancer controls (mean age, 44.55 years) were assessed. Patients reported significantly greater subjective cognitive functioning on the FACT-Cog total score and two subscales of perceived cognitive impairment and perceived cognitive ability (all p values impairment (r = -0.388, p = 0.034). When compared with non-cancer controls, a considerable proportion of gynaecological cancer survivors may exhibit subjective cognitive impairment. This study provides the first evidence of brain structural network alteration in gynaecological cancer patients at post-treatment, and offers novel insights regarding the possible neurobiological mechanism of cancer-related cognitive impairment (CRCI) in gynaecological cancer patients. As primary cancer treatment can result in a more random organisation of structural brain networks, this may reduce brain functional specificity and segregation, and have implications for cognitive impairment. Future prospective and longitudinal studies are needed to build upon the study findings in order to assess potentially relevant clinical and psychosocial variables and brain network measures, so as to more accurately understand the

    With the introduction of avoidant/restrictive food intake disorder (ARFID) in the Diagnostic and Statistical Manual - fifth edition, there is an increased need to understand the prevalence and pattern of food avoidance and restriction in adults. High rates of food allergy and intolerance in immunology clinic populations, and subsequent high rates of elimination diets, place these individuals at a greater risk of developing pathological eating behaviours. This descriptive cross sectional pilot study aims to provide preliminary data on the prevalence and nature of food avoidance and restriction in an adult population, and to explore the reasons for this behaviour. A self-administered questionnaire was designed and distributed to adults presenting to an immunology clinic and a general practice over the course of 6 months to describe the prevalence and nature of avoidant and restrictive eating behaviours in this population. Pearson's chi square test was used to examine the strength of a potential link to a formal diagnosis of avoidant restrictive food intake disorder in these patients. A total of 102 completed questionnaires were used for data analysis. Food avoidance or restriction was detected in 81 respondents (79%), with rates not significantly higher in the immunology clinic group compared to the general practice group ( p  = .242). Food allergy and intolerance were the most common reasons for disturbed eating patterns. Life impact secondary to food avoidance and restriction was reported by 26% of respondents, with significantly higher rates observed in the immunology clinic cohort compared to the general practice ( p  = .011). Eating disturbances similar to those characteristic of ARFID are very common in adults. Food avoidance and restriction due to perceived food allergy and intolerance are significant reasons for such disordered eating patterns, particularly in an immunology clinic population. Further investigation is needed to determine if such eating

    To compare the pregnancy outcome and cord blood cotinine levels between secondhand smokers and non-secondhand smokers. This was a cross-sectional comparative study in a Malaysian tertiary obstetric hospital involving 200 non-smoking pregnant women at term, of whom 100 were secondhand smokers and 100 were non-secondhand smokers. Those with multiple pregnancies, with a body mass index (BMI) of more than 30kg/m 2 or who delivered by Caesarean section were excluded. The participants' basic demographic details, delivery details, neonatal outcome and placental weight were recorded. Umbilical cord blood samples were obtained, and cord blood cotinine levels were measured with a Cotinine ELISA kit. The primary outcomes were baby's birth weight, length, and head circumference, Apgar score at 5min and placental weight. The secondary outcome was difference in cord blood cotinine levels between the two groups and the correlation of these differences with the neonatal outcome. The secondhand smoker group had significantly lower baby weight (2.94±0.31kg vs 3.05±0.40kg), head circumference (30.87±2.35cm vs 37.13±2.36cm), length (46.58±1.95cm vs 51.53±2.05cm) and placental weight (520±73.5g vs 596±61.3g) and significantly higher cord blood cotinine levels (16.35±12.84ng/mL vs 0.56±0.22ng/mL). Cord blood cotinine levels had significant negative correlations with placental weight (r=-0.461), baby's weight (r=-0.297), baby's head circumference (r=-0.501) and baby's length (r=-0.374). Secondhand smoke increases the incidence of adverse pregnancy outcomes (newborns'anthropometric measurements and placental weight) and causes higher cord blood cotinine levels.

    Full Text Available Untreated unilateral developmental dysplasia of the hip (DDH results in asymmetry of gait and hip strength and may lead to early osteoarthritis, which is commonly treated with a total hip arthroplasty (THA. There is limited knowledge about the obtained symmetry of gait and hip strength after the THA. The objectives of this cross-sectional study were to: a identify asymmetries between the operated and non-operated side in kinematics, kinetics and hip strength, b analyze if increased walking speed changed the level of asymmetry in patients c compare these results with those of healthy subjects.Women (18-70 year with unilateral DDH who had undergone unilateral THA were eligible for inclusion. Vicon gait analysis system was used to collect frontal and sagittal plane kinematic and kinetic parameters of the hip joint, pelvis and trunk during walking at comfortable walking speed and increased walking speed. Furthermore, hip abductor and extensor muscle strength was measured.Six patients and eight healthy subjects were included. In the patients, modest asymmetries in lower limb kinematics and kinetics were present during gait, but trunk lateral flexion asymmetry was evident. Patients' trunk lateral flexion also differed compared to healthy subjects. Walking speed did not significantly influence the level of asymmetry. The hip abduction strength asymmetry of 23% was not statistically significant, but the muscle strength of both sides were significantly weaker than those of healthy subjects.In patients with a DDH treated with an IBG THA modest asymmetries in gait kinematics and kinetics were present, with the exception of a substantial asymmetry of the trunk lateral flexion. Increased walking speed did not result in increased asymmetries in gait kinematics and kinetics. Hip muscle strength was symmetrical in patients, but significantly weaker than in healthy subjects. Trunk kinematics should be included as an outcome measure to assess the biomechanical

    Children are at higher risk of acquiring infections and developing severe disease. This study assessed the health care seeking behavior and associated factors of urban and rural mothers for common childhood illness in Northwest Ethiopia. A comparative community based cross-sectional study was conducted among urban and rural mothers living in the district. A multistage sampling technique was used to select the study participants. A pre-tested and structured questioner via interview was used to collect the data. Binary logistic regression analysis was used to identify associated factors. Odds ratio with 95% CI was computed to assess the strength of the associations. A total of 827 (274 urban and 553 rural) mothers were interviewed. Among these, 79.3% (95% CI: (76.5%, 82.06%)) of the mothers were sought health care in the district. Health care seeking behavior was higher among urban mothers (84.6%) than rural mothers (76.7%). Marital status, completion health extension package, and sex of child were significantly associated with health care seeking behavior of urban mothers. Whereas age of child, age and occupation of mothers, educational level of fathers, wealth quintile, and type of reported illness were significantly associated with rural mothers. Perceived severity of illness was significantly associated with both urban and rural mothers for health care seeking behavior. The overall health seeking behaviors of mothers for common childhood illness was high. However, urban mothers seek health care more than rural. Socio Economic position and types of reported illness has an effect for health seeking behavior of rural mothers. Whereas child sex preference and graduation status for health extension package has an effect for health care seeking behavior of urban mothers. Work on strengthen accessibility of health care services in the rural mothers and increase awareness of mothers about the disadvantage of sex preferences will improve the health care seek behavior of

    Full Text Available Cross-sectional study design is a type of observational study design. In a cross-sectional study, the investigator measures the outcome and the exposures in the study participants at the same time. Unlike in case–control studies (participants selected based on the outcome status or cohort studies (participants selected based on the exposure status, the participants in a cross-sectional study are just selected based on the inclusion and exclusion criteria set for the study. Once the participants have been selected for the study, the investigator follows the study to assess the exposure and the outcomes. Cross-sectional designs are used for population-based surveys and to assess the prevalence of diseases in clinic-based samples. These studies can usually be conducted relatively faster and are inexpensive. They may be conducted either before planning a cohort study or a baseline in a cohort study. These types of designs will give us information about the prevalence of outcomes or exposures; this information will be useful for designing the cohort study. However, since this is a 1-time measurement of exposure and outcome, it is difficult to derive causal relationships from cross-sectional analysis. We can estimate the prevalence of disease in cross-sectional studies. Furthermore, we will also be able to estimate the odds ratios to study the association between exposure and the outcomes in this design.

    Reduced postural control is thought to contribute to the development and persistence of chronic non-specific low back pain (CNLBP). It is therefore frequently assessed in affected patients and commonly reported as the average amount of postural sway while standing upright under a variety of sensory conditions. These averaged linear outcomes, such as mean centre of pressure (CP) displacement or mean CP surface areas, may not reflect the true postural status. Adding nonlinear outcomes and multi-segmental kinematic analysis has been reported to better reflect the complexity of postural control and may detect subtler postural differences. In this cross-sectional study, a combination of linear and nonlinear postural parameters were assessed in patients with CNLBP (n = 24, 24-75 years, 9 females) and compared to symptom-free controls (CG, n = 34, 22-67 years, 11 females). Primary outcome was postural control measured by variance of joint configurations (uncontrolled manifold index, UI), confidence ellipse surface areas (CEA) and approximate entropy (ApEn) of CP dispersion during the response phase of a perturbed postural control task on a swaying platform. Secondary outcomes were segment excursions and clinical outcome correlates for pain and function. Non-parametric tests for group comparison with P-adjustment for multiple comparisons were conducted. Principal component analysis was applied to identify patterns of segmental contribution in both groups. CNLBP and CG performed similarly with respect to the primary outcomes. Comparison of joint kinematics revealed significant differences of hip (P postural differences in CNLBP patients with low to moderate pain status.

    Informed consent is now accepted as the cornerstone of medical practice, with reasonable patient standards typically considered to be appropriate in the developed countries; however it is still challenged in many developing countries. The objective of this descriptive study was to evaluate the perceptions and practices among attending medical professionals in matters relating to informed consent in selected hospitals. A questionnaire-based cross sectional survey among doctors in the two tertiary care hospitals, one in Malaysia and the other in Kashmir, was performed. Awareness on informed consent was universal with "reasonable physician standard" as the most popular choice. As compared to doctors in Malaysia, doctors from Kashmir showed a tendency to reservedly disclose medical information (p-value equals 0.051) and withhold it, if it was deemed potentially harmful (p-value is less than 0.001) or requested so by relatives (p-value is less than 0.023). They also withheld some information from female patients (p-value is less than 0.001). When consent was refused despite needing lifesaving intervention, the majority of both respondents (73 percent versus 80 percent) considered intervention without consent to be justified. Respondents from Malaysia felt that parents could refuse treatment on their children's behalf on the basis of their beliefs (p-value is less than 0.001). Despite a very high awareness of informed consent, the model chosen reflected age-old medical paternalism. Doctors' opinions are accorded a larger role in clinical decision-making in Kashmir. The results emphasise the need for doctors to change their attitude and acknowledge the patient's autonomy, which is the basis of modern medical ethics, and yet still be aware of the cultural and religious views of the local population.

    Accurate expression for photoabsorption (photoionization) cross sections of high density system proposed recently is used to study the photoionization of solid gold. The results show that the present theoretical photoionization cross sections have good agreement both in structure and in magnitude with the experimental results of gold crystal. The studies also indicate that both the real part ε' and the imaginary part ε'' of the complex dielectric constant ε, and the dielectric influence function of a nonideal system have rich structures in low energy side with a range about 50 eV, and suggest that the influence of particle interactions of surrounding particles with the photoionized particle on the photoionization cross sections can be easily investigated using the dielectric influence function. The electron overlap effects are suggested to be implemented in the future studies to improve the accuracy of theoretical photoionization cross sections of a solid system.

    In the latest report of Ethiopian Demographic and Health Survey (EDHS) 2011, the maternal mortality ratio (MMR) was estimated at 676/100,000 live births, with total fertility rate at 4.8 and contraceptive prevalence rate at 29 %. Knowledge and utilization of long acting contraceptive in the Tigray region are low. This study aims at comparing and identifying factors related to the utilization of long acting contraceptive in urban versus rural settings of Ethiopia. A comparative community-based cross-sectional study, comprised of quantitative and qualitative methods, was conducted among 1035 married women in Wukro (urban area) and Kilteawlaelo district (rural area) in March, 2013. Stratified sampling technique was employed to approach the study participants. Data were analyzed using SPSS version 20. Multiple logistic regression analysis was used to identify the respective effect of independent predictors on utilization of long acting contraceptive. The proportion of long acting contraceptive use among the respondents was 19.9 % in the town of Wukro and 37.8 % in the district of Kilteawlaelo. Implanon was the most common type of contraceptive used in both districts, urban (75 %) and rural (94 %). The odds of using the long acting contraceptive method were three times higher among married women in the rural areas as compared with the urban women [AOR = 3. 30; 95 %, CI:2.17, 5.04]. No or limited support from male partners was an obstacle to using long acting contraceptive method [AOR = 0. 24, 95 of CI: 0.13, 0.44]. Moreover, married women whose partner did not permit them to use long acting contraceptive [AOR = 0. 47, 95 % of CI: 0.24, 0.92] and women who attended primary education [AOR = 0.24, 95 %, CI: 0.13, 0.44] were significantly associated with long acting contraceptive use. Overall, the proportion of long acting contraceptive use has found to be low. Rural women were more likely to use long acting contraceptives as compared to urban women

    Full Text Available Ethiopia is ninth among the world high tuberculosis (TB burden countries, pastoralists being the most affected population. However, there is no published report whether the behavior related to TB are different between pastoralist and the sedentary communities. Therefore, the main aim of this study is to assess the pastoralist community knowledge, attitude and perceived stigma towards tuberculosis and their health care seeking behavior in comparison to the neighboring sedentary communities and this may help to plan TB control interventions specifically for the pastoralist communities.A community-based cross-sectional survey was carried out from September 2014 to January 2015, among 337 individuals from pastoralist and 247 from the sedentary community of Kereyu district. Data were collected using structured questionnaires. Three focus group discussions were used to collect qualitative data, one with men and the other with women in the pastoralist and one with men in the sedentary groups. Data were analyzed using Statistical Software for Social Science, SPSS V 22 and STATA.A Lower proportion of pastoralists mentioned bacilli (bacteria as the cause of PTB compared to the sedentary group (63.9% vs. 81.0%, p<0.01, respectively. However, witchcraft was reported as the causes of TB by a higher proportion of pastoralists than the sedentary group (53.6% vs.23.5%, p<0.01, respectively. Similarly, a lower proportion of pastoralists indicated PTB is preventable compared to the sedentary group (95.8% vs. 99.6%, p<0.01, respectively. Moreover, majority of the pastoralists mentioned that most people would reject a TB patient in their community compared to the sedentary group (39.9% vs. 8.9%, p<0.001, respectively, and the pastoralists expressed that they would be ashamed/embarrassed if they had TB 68% vs.36.4%, p<0.001, respectively.The finding indicates that there is a lower awareness about TB, a negative attitude towards TB patients and a higher perceived

    Polycystic ovary syndrome (PCOS) is the most common chronic endocrine disorder affecting women of reproductive age. This study aimed to compare the HRQoL of South Asian and white Caucasian women with PCOS, given that it is particularly common among women of South Asian origin and they have been shown to have more severe symptoms. The Polycystic Ovary Syndrome Questionnaire (PCOSQ) and the Short Form-36 (SF-36) were administered in a cross-sectional survey to 42 South Asian and 129 Caucasian women diagnosed with PCOS recruited from the gynaecology outpatient clinics of two university teaching hospitals in Sheffield and Leeds. Additional clinical data was abstracted from medical notes. Normative data, collected as part of the Oxford Health and Lifestyles II survey, was obtained to compare SF-36 results with ethnically matched women from the general UK population. Using the SF-36, normative HRQoL scores for women of South Asian origin were lower than for Caucasian women. Given this lower baseline we tested whether the same relationship holds true among those with PCOS. Although HRQoL scores for women with PCOS were lower than normative data for both groups, South Asian women with PCOS did not have poorer HRQoL than their Caucasian counterparts. For both the SF-36 and PCOSQ, mean scores were broadly the same for both Asian and Caucasian women. For both groups, the worst two HRQoL domains as measured on the PCOSQ were 'infertility' and 'weight', with respective scores of 35.3 and 42.3 for Asian women with PCOS compared to 38.6 and 35.4 for Caucasian women with PCOS. The highest scoring domain for South Asian women with PCOS was 'menstrual problems' (55.3), indicating best health, and was the only statistically significant difference from Caucasian women (p = 0.01). On the SF-36, the lowest scoring domain was 'Energy & Vitality' for Caucasian women with PCOS, but this was significantly higher for Asian women with PCOS (p = 0.01). The best health status for both groups

    In developing country most of human infectious diseases are caused by eating contaminated food. Estimated nine out ten of the diarrheal disease is attributable to the environment and associated with risk factors of poor food hygiene practice. Understanding the risk of eating unsafe food is the major concern to prevent and control food borne diseases. The main goal of this study was to assessing food hygiene practices and its associated factors among model and non model households at Abobo district. This study was conducted from 18 October 2013 to 13 June 2014. A community-based comparative cross-sectional study design was used. Pretested structured questionnaire was used to collect data. A total of 1247 households (417 model and 830 non model households) were included in the study from Abobo district. Bivariate and multivariate logistic regression analysis was used to identify factors associated with outcome variable. The study revealed that good food hygiene practice was 51%, of which 79% were model and 36.70% were non model households. Type of household [AOR: 2.07, 95% CI: (1.32-3.39)], sex of household head [AOR: 1.63, 95% CI: (1.06-2.48)], Availability of liquid wastes disposal pit [AOR: 2.23, 95% CI: (1.39,3.63)], Knowledge of liquid waste to cause diseases [AOR: 1.95, 95% (1.23,3.08)], and availability of functional hand washing facility [AOR: 3.61, 95% CI: (1.86-7.02)] were the factors associated with food handling practices. This study revealed that good food handling practice is low among model and non model households. While type of household (model versus non model households), sex, knowledge of solid waste to cause diseases, availability of functional hand washing facility, and availability of liquid wastes disposal pit were the factors associated with outcome variable. Health extension workers should play a great role in educating households regarding food hygiene practices to improve their knowledge and practices of the food hygiene.

    Blood can save millions of lives. Even though people do not donate blood regularly, there is a constant effort to balance the supply and demand of blood. The aim of this study was, therefore, to determine the knowledge, attitude and practice of blood donation between university students. The comparative cross sectional study design was used in Adama Science and Technology University and Arsi University from April 11-May 2, 2016.360 students were selected using stratified sampling. Frequencies and proportions were computed. Chi-Square and logistic regressions were carried out and associations were considered significant at p students of Arsi University and Non-Health Science students of Adama Science and Technology University. The gender of the students (AOR = 3.150, 95% CI: 1.313, 7.554) was a significant predictor of the level of knowledge of Health Science students. The ethnicity of students (AOR = 2.085, 95% CI: 1.025, 4.243) was a significant predictor of the level of an attitude of Health Science students and gender of students (AOR = 0.343, 95% CI: 0.151, 0.779) was a significant predictor of the level of an attitude of Health Science students. Concerning Non-Health Science students, religion (AOR = 10.173, 95% CI: 1.191, 86.905) and original residence (AOR = 0.289, 95% CI: 0.094, 0.891) were a significant predictor of the level of knowledge of Non-Health Science students. Gender (AOR = 0.389, 95% CI: 0.152, 0.992) and Year of study (AOR = 0.389(0.164, 0.922) were significant predictor of level of attitude of Non-Health Science students. Year of study (AOR = 5.159, 95% CI: 1.611, 16.525) was a significant predictor of level of practice of Health Science students. Significant knowledge difference and attitude difference were observed between students from Arsi University and Adama Science and Technology University.

    Cotton dust induced respiratory disorders are dramatically increased over the globe, especially the problem is serious in developing countries. Respiratory symptoms, such as cough, phlegm, wheezing, shortness of breath, chest tightness, chronic bronchitis, and byssinosis are common among workers exposed to cotton dust. However, in Ethiopia, the magnitude of the problem is not well known and information is limited about the risk factors. Therefore, this study was aimed to assess the prevalence of respiratory symptoms and associated factors. A Comparative cross-sectional study design was employed. A total of 413 (276 exposed and 137 unexposed) participants were included in the study. Stratified and simple random sampling techniques were used to select exposed and unexposed groups to cotton dust respectively. Multivariable binary logistic regression analyses was performed to identify variables associated with respiratory symptoms and adjusted odds ratio (AOR) was used to determine the strength of associations. Significance level was obtained at 95% confidence interval (CI) and p -value ≤0.05. The prevalence of self-reported respiratory symptoms was 47.8% (95% CI: 41.3, 53.7%) and 15.3% (95% CI: 9.6, 22.3%) among exposed and control groups respectively. Sex (AOR = 2.1, 95% CI: 1.29, 3.45), service year (AOR = 2.38, 95% CI: 1.19, 4.71) and ventilation (AOR = 2.4, 95% CI: 1.17, 4.91) were factors significantly associated with respiratory symptoms. Furthermore, working department such as; ginning (AOR = 5.1, 95% CI: 2.13, 12.16), spinning (AOR = 4.96, 95% CI: 2.18, 11.29), weaving (AOR = 5.9, 95% CI: 2.46, 14.27) and blowing working departments (AOR = 5.14, 95% CI: 1.4, 18.94) were significantly associated with respiratory disorders. The prevalence of self-reported respiratory symptoms was higher among workers exposed to cotton dust than unexposed workers. Sex, service year, working department and work unit ventilation were predictor

    Full Text Available Background. Trachoma is the most common infectious cause of blindness worldwide. Once an epidemic in most parts of the world, it has largely now disappeared from developed countries. However, it continues to be endemic in many developing countries like Ethiopia. Even if several studies were conducted in different parts of Ethiopia, most of them did not show the independent predictors for rural and urban children separately. Therefore, this study aimed at assessing the prevalence and associated factors of active trachoma in urban and rural children. Methods. Community based comparative cross-sectional study was conducted in Dera woreda. Multistage sampling technique was used to select 671 children of one up to nine years of age. Data were collected by face to face interview and observation using a structured and pretested questionnaire. Binary Logistic Regression Model was fitted to consider adding independent predictors of outcome. Results. Out of 671 children, 20 (9.3% of urban and 85 (18.6% of rural children were positive for active trachoma. Having discharge on eye (AOR = 6.9, 95% CI: 1.79–27.89, presence of liquid waste around the main house (AOR = 5.6, 95% CI: 1.94–16.18, and living in households without latrine (AOR = 4.39, 95% CI: 1.39–13.89 were significantly associated with active trachoma of urban children. Rural children who had discharge on their eye (AOR = 5.86, 95% CI: 2.78–12.33, those who had unclean face (AOR = 4.68, 95% CI: 2.24–9.81, and those living in households with feces around their main houses (AOR = 1.94, 95% CI: 1.04–3.62 were significantly associated with active trachoma. Conclusion. The result showed that the prevalence of active trachoma in urban areas of the district was below WHO threshold of 10% to determine trachoma as public health problem. However, in rural areas of the district it is far from elimination of trachoma as a public health problem. Thus, in order to improve awareness of the community

    To promote child development, parenting stress, and maternal-child interactions among mothers of various nationalities must be understood. The purpose of this study was to investigate maternal-child interactions according to the mother's nationality among married immigrant mothers from the Philippines, Vietnam, and Korea. This study employed a descriptive, cross-sectional design. Inclusion criteria were mothers who had children of preschool age. A total of 348 mothers were interviewed: 142 Korean mothers, 84 immigrant mothers from the Philippines, and 122 immigrant mothers from Vietnam. Parenting stress ( p maternal-child interactions ( p = .023) differed according to the mother's nationality. By delineating the nurturing characteristics of each country, the results of this study can help immigrant mothers develop maternal-child relationships that aid culturally congruent adjustment to their new culture. The characteristics of maternal-child interactions according to the mother's nationality may inform parent education in multicultural societies.

DPs were identified by two methods: a priori approach (a priori DPs) and cluster analysis (data-driven DPs). The association between obesity and DPs and three single dietary characteristics was examined using multiple logistic regression analysis. Four data-driven DPs were obtained: 'Low-fat-Low-fibre-Low-varied' (21.2%), 'Low-fibre' (29.1%), 'Low-fat' (25.0%) and 'High-fat-Varied' (24.7%). Three a priori DPs were pre-defined: 'Non-healthy' (16.6%), 'Neither-pro-healthy-nor-non-healthy' (79.1%) and 'Pro-healthy' (4.3%). Girls with 'Low-fibre' DP were less likely to have central obesity (adjusted odds ratio (OR) = 0.36; 95% confidence interval (CI): 0.17, 0.75) than girls with 'Low-fat-Low-fibre-Low-varied' DP (reference group, OR = 1.00). No significant associations were found between a priori DPs and overweight including obesity or central obesity. The majority of girls with 'Non-healthy' DP were also classified as 'Low-fibre' DP in the total sample, in girls with overweight including obesity and in girls with central obesity (81.7%, 80.6% and 87.3%, respectively), while most girls with 'Pro-healthy' DP were classified as 'Low-fat' DP (67.8%, 87.6% and 52.1%, respectively). We found that the a priori approach as well as cluster analysis can be used to derive opposite health-oriented DPs in Polish females. Both methods have provided disappointing outcomes in explaining the association between obesity and DPs. The cluster analysis, in comparison with the a priori approach, was more useful for finding any

    Food insecurity remains highly prevalent in developing countries and over the past two decades it has increasingly been recognized as a serious public health problem, including in Ethiopia. An emerging body of literature links food insecurity to a range of negative health outcomes and causes of a decline in productivity. The objectives of the present study were to determine the level of food insecurity in East Gojjam zone where the productive safety net program is available, and in West Gojjam zone where there is no program, and to identify the determinants of food insecurity in both East and West Gojjam zones of Amhara Region, Ethiopia. Community based comparative cross-sectional study design was used from 24 May 2013- 20 July 2013. Multistage sampling technique was implemented. A total of 4110 randomly selected households in two distinct populations were approached to be included in the study. Availability and absence of the productive safety net program between the two study areas was used to categorize them as comparative groups; otherwise the two communities are comparable in many socio-cultural characteristics. The household food security access scale questionnaire, developed by the Food and Nutrition Technical Assistant Project, was used to measure food security level. Socio-demographic and other household level information were collected by using a structured questionnaire. The binary logistic regression model was used to assess factors associated with food insecurity. From the total 4110 households, 3964 (96.45 %) gave complete responses. The total prevalence of food insecurity was 55.3 % (95 % CI: 53.8, 56.8). To compare food insecurity levels between the two zones, nearly sixty percent, 59.2 % (95 % CI: 57 %, 61.4 %) of the East Gojjam and 51.3 % (95 % CI: 49.1 %, 53.5) of West Gojjam households were food insecure.

    Full Text Available Abstract Background Polycystic ovary syndrome (PCOS is the most common chronic endocrine disorder affecting women of reproductive age. This study aimed to compare the HRQoL of South Asian and white Caucasian women with PCOS, given that it is particularly common among women of South Asian origin and they have been shown to have more severe symptoms. Methods The Polycystic Ovary Syndrome Questionnaire (PCOSQ and the Short Form-36 (SF-36 were administered in a cross-sectional survey to 42 South Asian and 129 Caucasian women diagnosed with PCOS recruited from the gynaecology outpatient clinics of two university teaching hospitals in Sheffield and Leeds. Additional clinical data was abstracted from medical notes. Normative data, collected as part of the Oxford Health and Lifestyles II survey, was obtained to compare SF-36 results with ethnically matched women from the general UK population. Using the SF-36, normative HRQoL scores for women of South Asian origin were lower than for Caucasian women. Given this lower baseline we tested whether the same relationship holds true among those with PCOS. Results Although HRQoL scores for women with PCOS were lower than normative data for both groups, South Asian women with PCOS did not have poorer HRQoL than their Caucasian counterparts. For both the SF-36 and PCOSQ, mean scores were broadly the same for both Asian and Caucasian women. For both groups, the worst two HRQoL domains as measured on the PCOSQ were 'infertility' and 'weight', with respective scores of 35.3 and 42.3 for Asian women with PCOS compared to 38.6 and 35.4 for Caucasian women with PCOS. The highest scoring domain for South Asian women with PCOS was 'menstrual problems' (55.3, indicating best health, and was the only statistically significant difference from Caucasian women (p = 0.01. On the SF-36, the lowest scoring domain was 'Energy & Vitality' for Caucasian women with PCOS, but this was significantly higher for Asian women with PCOS (p

    Quality of life can be used to measure the effect of intervention on health related conditions. Health insurance contributes positive effect on availability of medical supplies and empowerment of women and children on financial healthcare. Therefore, the study was aimed to measure the impact of Community-Based Health Insurance on HRQoL and associated socio-demographic factors. A comparative community based cross-sectional study was employed. Data was collected by trained enumerators using World Health Organization QoL-BREF tool from a sample of 1964 (982 CBHI insured and 982 un-insured) household heads selected by probability proportional to size. A descriptive summery, simple and multiple linear regression analysis was applied to describe the functional predictors of HRQoL. The study was ethically approved by IRB of Wolkite University. The HRQoL score among CBHI insured family heads was 63.02 and 58.92 for un-insured family heads. The overall variation in HRQoL was explained due to; separated marital condition which reduced the HRQoL by 4.30% than those living together [ β  = - 0.044, 95% CI (- 5.67, - 0.10)], daily laborer decreased HRQoL by 7.50% [ β  = - 0.078, 95% CI (- 12.91, - 4.10)], but employment increased by 5.65% than farmers [ β  = 0.055, 95% CI (2.58, 17.59)]. QoL increased by 6.4 and 6.93% among primary and secondary level educated household heads than those household heads who could not read and write [ β  = 0.062, 95% CI (0.75, 4.31)] and [ β  = 0.067, 95% CI (1.84, 7.99)], respectively. As family size increased by one households' head, HRQoL decreased by 18.21% [ β  = - 0.201, 95% CI (- 2.55, - 1.63)], as wealth index increased by one unit, HRQoL decreased by 32.90% [ β  = - 0.306, 95% CI (- 5.15, - 3.86)] and QoL among CBHI insured household heads increased by 12.41% than those un-insured family heads [ β  = 0.117, 95% CI (2.98, 6.16)].

    Despite the availability of standard treatment guidelines for malaria in Pakistan adherence to protocols by prescribers is poor. This descriptive, cross-sectional study aimed to explore the perceptions and knowledge of prescribers in Islamabad and Rawalpindi cities towards adherence to standard treatment guidelines for malaria. A questionnaire was distributed to a random sample of 360 prescribers; 64.7% were satisfied with the available antimalarial drugs and 41.3% agreed that antimalarial drugs should only be prescribed after diagnostic testing. Only half the prescribers had the guidelines available in their health facility. Almost all the prescribers (97.7%) agreed that there was a need for more educational programmes about the guidelines. Most prescribers were unaware of the correct standard treatment regimen for Plasmodium falciparum and P. vivax malaria. There were no differences in knowledge between males and females, but prescribers having more experience, practising as general practitioners and working in private health-care facilities possessed significantly better knowledge than their counterparts.

    Full Text Available Objective: To study the correlation and effect of sequential measurement of intraocular pressure (IOP with Goldmann applanation tonometer (GAT, ocular response analyzer (ORA, dynamic contour tonometer (DCT, and Corvis ST. Setting and Design: Observational cross-sectional series from the comprehensive clinic of a tertiary eye care center seen during December 2012. Methods: One hundred and twenty-five study eyes of 125 patients with normal IOP and biomechanical properties underwent IOP measurement on GAT, DCT, ORA, and Corvis ST; in four different sequences. Patients with high refractive errors, recent surgeries, glaucoma, and corneal disorders were excluded so as to rule out patients with evident altered corneal biomechanics. Statistical Analysis: Linear regression and Bland-Altman using MedCalc software. Results: Multivariate analysis of variance with repeated measures showed no influence of sequence of device use on IOP (P = 0.85. Linear regression r 2 between GAT and Corvis ST, Corvis ST and Goldmann-correlated IOP (IOPg, and DCT and Corvis ST were 0.37 (P = 0.675, 0.63 (P = 0.607, and 0.19 (P = 0.708, respectively. The Bland-Altman agreement of Corvis ST with GAT, corneal compensated IOP, and IOPg was 2 mmHg (−5.0 to + 10.3, −0.5 mmHg (−8.1 to 7.1, and 0.5 mmHg (−6.2 to 7.1, respectively. Intraclass correlation coefficient for repeatability ranged from 0.81 to 0.96. Conclusions: Correlation between Corvis ST and ORA was found to be good and not so with GAT. However, agreement between the devices was statistically insignificant, and no influence of sequence was observed.

    Human immunodeficiency virus (HIV) is a serious disease which can be associated with various activity limitations and participation restrictions. The aim of this paper was to describe how HIV affects the functioning and health of people within different environmental contexts, particularly with regard to access to medication. Four cross-sectional studies, three in South Africa and one in Brazil, had applied the International Classification of Functioning, Disability and Health (ICF) as a classification instrument to participants living with HIV. Each group was at a different stage of the disease. Only two groups had had continuing access to antiretroviral therapy. The existence of these descriptive sets enabled comparison of the disability experienced by people living with HIV at different stages of the disease and with differing access to antiretroviral therapy. Common problems experienced in all groups related to weight maintenance, with two-thirds of the sample reporting problems in this area. Mental functions presented the most problems in all groups, with sleep (50%, 92/185), energy and drive (45%, 83/185), and emotional functions (49%, 90/185) being the most affected. In those on long-term therapy, body image affected 93% (39/42) and was a major problem. The other groups reported pain as a problem, and those with limited access to treatment also reported mobility problems. Cardiopulmonary functions were affected in all groups. Functional problems occurred in the areas of impairment and activity limitation in people at advanced stages of HIV, and more limitations occurred in the area of participation for those on antiretroviral treatment. The ICF provided a useful framework within which to describe the functioning of those with HIV and the impact of the environment. Given the wide spectrum of problems found, consideration could be given to a number of ICF core sets that are relevant to the different stages of HIV disease. Copyright © 2010 Chartered Society of

    Health literacy is a major problem worldwide and adversely affects an individual's health. The aim of the present study was to assess health literacy level among Saudi population. A cross-sectional study was conducted among a randomly selected population (n = 500) in Saudi Arabia. The questionnaire comprised of questions pertaining to demographic characteristics, health literacy and health information. Health literacy was measured by REALM-R test. Internal reliability was determined using Cronbach's alpha coefficient. The majority of the respondents had intermediate (43.8%) and basic (34.4%) health literacy levels. A higher percentage among men had intermediate (59.8%) and basic (70.93%) health literacy levels compared with women. About 30% of respondents had difficulty in understanding health screening tests and disease treatment. More than half of participants (52.4%) had difficulty in finding health information. The REALM-R test revealed that about 42.6% of individuals with score of >6 had adequate health literacy compared with 57.4% with score of ≤6 had inadequate health literacy. The present study demonstrated that a majority of Saudi individuals had inadequate health literacy that associated with poor knowledge of health information. Our findings highlighted the importance of understanding the status of health literacy among Saudis and the need for educational programs to raise the health literacy awareness among Saudi population. © The Author 2017.

    Objective Research on health services for immigrants has mostly been concerned with access barriers but rarely with appropriateness and responsiveness of care. We assessed whether appropriateness and responsiveness of care depend on migration status, using provision of neuraxial anaesthesia (NA) during labour as indicator. In relation to their migration status, we analysed whether (1) women undergoing elective or secondary/urgent secondary caesarean sections (ESCS) appropriately receive NA (instead of general anaesthesia), (2) women delivering vaginally appropriately receive NA and (3) women objecting to NA, for example, for religious reasons, may deliver vaginally without receiving NA (provider responsiveness). Design Cross-sectional study. Setting Three obstetric hospitals in Berlin, Germany. Methods Questionnaire survey covering 6391 women with migration history (first and second generations) and non-immigrant women giving birth; data linkage with routine obstetric data. We assessed the effects of migrant status, German language proficiency, religion and education on the provision of NA (primary outcome) after adjusting for other maternal and obstetric parameters. Results The chance of receiving NA for elective/ESCS was independent of migrant status after controlling for confounding variables (adjusted OR (aOR) 0.93, 95% CI 0.65 to 1.33). In vaginal deliveries, first (but not second) generation women (aOR 0.79, 95% CI 0.65 to 0.95), women with low German language skills (aOR 0.77, 95% CI 0.58 to 0.99) and women with low educational attainment (aOR 0.62, 95% CI 0.47 to 0.82) had lower chances of receiving NA; there was no evidence of overprovision among women with strong affinity to Islam (aOR 0.77, 95% CI 0.63 to 0.94). Conclusions We found evidence for underprovision of care among first-generation immigrants, among women with low German language proficiency and particularly among all women with low educational attainment, irrespective of migration

    This study investigated demographic factors, experience of burn/care and first aid course attendance as factors influencing burn first aid knowledge. A cross-sectional study was undertaken using convenience sampling of members of sporting and recreation clubs. The main outcome measure was the proportion of correct responses to multiple-choice questions relating to four burn scenarios: (1) scald, (2) contact burn, (3) ignited clothing, and (4) chemical burn. A total of 2602 responses were obtained. Large gaps (30-50% incorrect answers) were identified in burn first aid knowledge across all scenarios. 15% more individuals gave correct answers if they had attended a first aid course compared to those who had not (pfirst aid knowledge. Gender and age were significant predictors of first aid course attendance, with males and younger (≤25 years) and older (≥65 years) age-groups less likely to have attended a first aid course. In this sample, first aid training undertaken within the last 5 years with a specific burns component was associated with enhanced burn first aid knowledge. Copyright © 2013 Elsevier Ltd and ISBI.

    Sleep disorders (SDs), particularly sleep deprivation, may alter the immune system and induce systemic inflammation. Recent evidence supports an association between SDs and periodontal diseases. This cross-sectional epidemiological study aims to compare oral health variables, such as the amount of plaque/calculus, gingival inflammation, and masticatory function, in individuals with and without SDs. The study population consisted in a French cohort of individuals who underwent medical and oral examinations between 2012 and 2013. Multivariate logistic regression and general linear models were used for group comparisons. Over a total of 29,870 individuals, 11,185 (37.4 %) reported to suffer from SDs on a regular basis. Compared to individuals without SDs, SD individuals were older (mean age 44.2 vs. 45.3 years; p < 0.0001), prevalently female (38.6 vs. 52.1 %; p < 0.0001), and with higher BMI (25.3 vs. 25.7; p < 0.0001). Moreover, SD individuals displayed a significantly higher prevalence of comorbidities, higher level of gingival inflammation (adjusted odds ratio 1.22 [95 % confidence interval 1.13-1.32]), and lower masticatory function (1.45 [1.33-1.58]). Short sleepers (<6 h of sleep/night) were found to be at an increased risk of gingival inflammation (1.25 [1.1-1.4]). SD individuals with moderate-to-high gingival inflammation showed a significantly increased risk of cardiovascular disease (1.39 [1.04-1.84]) compared to SD individuals with low or no gingival inflammation. Individuals with self-report SDs are at increased risk of gingival inflammation. The coexistence of SDs and gingival inflammation is associated with an increased risk of cardiovascular diseases. These findings provide evidence for an association between SDs and gingival inflammation and support further clinical and experimental studies.

  17. Augmented cross-sectional studies with abbreviated follow-up for estimating HIV incidence.

    Cross-sectional HIV incidence estimation based on a sensitive and less-sensitive test offers great advantages over the traditional cohort study. However, its use has been limited due to concerns about the false negative rate of the less-sensitive test, reflecting the phenomenon that some subjects may remain negative permanently on the less-sensitive test. Wang and Lagakos (2010, Biometrics 66, 864-874) propose an augmented cross-sectional design that provides one way to estimate the size of the infected population who remain negative permanently and subsequently incorporate this information in the cross-sectional incidence estimator. In an augmented cross-sectional study, subjects who test negative on the less-sensitive test in the cross-sectional survey are followed forward for transition into the nonrecent state, at which time they would test positive on the less-sensitive test. However, considerable uncertainty exists regarding the appropriate length of follow-up and the size of the infected population who remain nonreactive permanently to the less-sensitive test. In this article, we assess the impact of varying follow-up time on the resulting incidence estimators from an augmented cross-sectional study, evaluate the robustness of cross-sectional estimators to assumptions about the existence and the size of the subpopulation who will remain negative permanently, and propose a new estimator based on abbreviated follow-up time (AF). Compared to the original estimator from an augmented cross-sectional study, the AF estimator allows shorter follow-up time and does not require estimation of the mean window period, defined as the average time between detectability of HIV infection with the sensitive and less-sensitive tests. It is shown to perform well in a wide range of settings. We discuss when the AF estimator would be expected to perform well and offer design considerations for an augmented cross-sectional study with abbreviated follow-up. © 2011, The

    Farmers are exposed to multiple air contaminants that may interact with tobacco smoking in the development of respiratory diseases. Farmers are currently considered to smoke less than non-farmers, but precise data in different categories of age and farming activities are lacking. Smoking habits were studied in a cross-sectional study involving 4105 farmers and 996 non-farming controls aged 40-74 years in 9 French departments between October 2012 and May 2013. Three age groups were defined (40-54, 55-64 and 65-74years). Farmers were divided into four activity groups, namely cattle breeders, livestock farmers working in confined spaces, crop farmers and others. Smoking prevalence was compared between farmers and controls, and odds ratios (ORs) for smoking adjusted for age were calculated. The adjusted OR for ever-smoking was lower among farmers than among non-farmers in all age categories, but the ORs for current smoking were similar in farmers and controls. Smoking prevalence varied according to the type of farming activity, and was lower than in non-farming controls only among cattle breeders and confined livestock farmers. In farmers, the proportion of smokers was higher in the youngest age categories compared with the older age classes. Our results confirm that the prevalence of ever-smokers is lower in farmers than in non-farmers. Nevertheless, our data show that active smoking prevalence is similar in farmers and in non-farmers. This suggests that farmers, just like non-farmers, should be targeted by primary prevention campaigns against smoking.

    Celebrities are at risk for premature mortality as well as drug-related death. Despite being a vulnerable patient group, celebrities influence people's health behaviours through biological, psychological and social processes. Therefore, celebrity endorsement of the topic could be one way to challenge the current "opioid endemic". Our aim was to better understand the factors surrounding drug-related celebrity deaths by investigating the incidence as well as substances used between 1970 and 2015 using a cross-sectional study design. We searched public databases for drug-related celebrity deaths between 1970 and 2015. They were categorized for sex, profession, age at death, year of death and substances involved. The main outcome measures are descriptive values including number of drug deaths per year and substances involved. Secondary outcome measures are analytical questions to examine whether and which factors influence age at death and year of death (e.g. type of substance use disorder). We identified 220 celebrities who died a drug-related death with a clear indication of involved substances between 1970 and 2015. The average age at death was 38.6 years; 75% were male. Most celebrities died between the age of 25 and 40. The number of drug-related deaths increased in the 21st century, with a significant increase in the use of prescription opioids. Deaths involving prescription opioids and heroin were associated with a significantly lower mean age at death compared to deaths where these substances were not involved. Compared to the 20th century, the total number of celebrities who died from a drug-related death in the 21st century increased, possibly due to an increased involvement of prescription opioids. Negative effects on individual health decisions of celebrity's followers could be the result.

  20. Cross-section uncertainty study of the NET shielding blanket

    The Next European Torus (NET) is foreseen as the next step in the European development towards the controlled use of thermonuclear fusion. Detail design of the shielding blanket protecting the peripherals, more especially the super-conducting coils, is well advanced. A cross-section uncertainty, i.e. a study of the expected inaccuracy due to the nuclear cross-section data, has been done for the neutron-gamma reactions in the insulation of the coils for such a design. As an extension of previous work on the NET shielding blanket (e.g. MCNP calculations), it was deemed necessary to estimate the accuracy attainable with transport codes in view of the uncertainties in microscopic cross-sections. The code used, SENSIBL, is based on perturbation theory and uses covariance files, COVFILS-2, for the cross-section data. This necessitates forward and adjoint flux calculations with a transport code (e.g. ONEDANT, TRISM) and folding the information contained in these coupled fluxes with the accuracy estimates of the evaluators of the ENDF/B-V files. Transport, P 5 S 12 , calculations were done with the ONEDANT code, for a shielding blanket design with 714 MW plasma fusion power. Several runs were done to obtain well converged forward and adjoint fluxes (ca. 1%). The forward and adjoint integral responses agree to 2%, which is consistent with the above accuracy. The n-γ response was chosen as it is typical of the general accuracy and is available for all materials considered. The present version of SENSIBL allows direct use of the geometric files of ONEDANT (or TRISM) which simplifies the input. Covariance data is not available at present in COVFILS-2 for all of the materials considered. Only H, C, N, O, Al, Si, Fe, Ni, and Pb could be considered, the big absentee being copper. The resulting uncertainty for the neutron-gamma reactions in the insulation of the coil was found to be 17%. Simulating copper by aluminium produces a negligible increase in the uncertainty, mainly

    Cross-sectional designs are often used to monitor the proportion of infections and other post-surgical complications acquired in hospitals. However, conventional methods for estimating incidence proportions when applied to cross-sectional data may provide estimators that are highly biased, as cross-sectional designs tend to include a high proportion of patients with prolonged hospitalization. One common solution is to use sampling weights in the analysis, which adjust for the sampling bias inherent in a cross-sectional design. The current paper describes in detail a method to build weights for a national survey of post-surgical complications conducted in Israel. We use the weights to estimate the probability of surgical site infections following colon resection, and validate the results of the weighted analysis by comparing them with those obtained from a parallel study with a historically prospective design.

    The purpose of this study was to examine by proton spectroscopy for any difference in cerebral metabolites in patients taking part in the Concorde study (comparing the efficacy of immediate versus deferred treatment with zidovudine on asymptomatic HIV infected individuals). Forty seven HIV positive male patients [29 immediate, 18 deferred zidovudine] were examined in the last 9 months of the therapeutic trial. Magnetic resonance imaging and proton spectroscopy were performed at 1.5 Tesla using a single voxel placed in the parieto-occipital white matter. No significant difference was found in metabolite ratios comparing immediate versus deferred zidovudine (NA/NA+Cho+Cr 0.52 vs. 0.52). High quality spectra were acquired in relatively large numbers of patients and logistically spectroscopy may be applied to clinical therapeutic studies.

    Optimizing methods for genital specimen collection to accurately characterize mucosal immune responses is a priority for the HIV prevention field. The menstrual cup (MC) has been proposed as an alternative to other methods including cervicovaginal lavage (CVL), but no study has yet formally compared these two methods. Forty HIV-infected, antiretroviral therapy-naïve women from the CAPRISA 002 acute HIV infection cohort study were randomized to have genital fluid collected using the MC with subsequent CVL, or by CVL alone. Qualitative data, which assessed levels of comfort and acceptability of MC using a 5-point Likert scale, was collected. Luminex multiplex assays were used to measure HIV-specific IgG against multiple gene products and 48 cytokines. The majority (94%) of participants indicated that insertion, wearing and removal of the MC was comfortable. Nineteen MCs with 18 matching, subsequent CVLs and 20 randomized CVLs were available for analysis. Mucosal IgG responses against four HIV-antigens were detected in 99% of MCs compared to only 80% of randomized CVLs (p = 0.029). Higher specific antibody activity and total antibodies were observed in MCs compared to CVL (all p<0.001). In MCs, 42/48 (88%) cytokines were in the detectable range in all participants compared to 27/48 (54%) in CVL (p<0.001). Concentrations of 22/41 cytokines (53.7%) were significantly higher in fluid collected by MC. Both total IgG (r = 0.63; p = 0.005) and cytokine concentrations (r = 0.90; p<0.001) correlated strongly between MC and corresponding post-MC CVL. MC sampling improves the detection of mucosal cytokines and antibodies, particularly those present at low concentrations. MC may therefore represent an ideal tool to assess immunological parameters in genital secretions, without interfering with concurrent collection of conventional CVL samples.

    Lung transplant (LuTx) patients are routinely immunized against tetanus and diphtheria. However, few studies have been done to measure serologic immunity in the transplant population. The primary objective of this study was to compare tetanus and diphtheria antibody concentrations in LuTx vs. healthy subjects. Serum was used from an available sample of 111 total individuals (n = 36 healthy; n = 75 LuTx). Tetanus and diphtheria antibody concentrations were measured using an enzyme-linked immunosorbant assay method. A statistically significant difference in both tetanus and diphtheria antibody concentrations was found between the groups. The median concentration of tetanus antibody was higher for healthy individuals compared with the LuTx group (3.2 IU/mL [1.2-5.2 interquartile range {IQR}] vs. 1.3 IU/mL [0.4-2.6 IQR], respectively; P = 0.0001). No difference in time was found since the last tetanus-diphtheria vaccine or tetanus-diphtheria-pertussis vaccine dose between the groups (healthy 76.5 months [16-114 IQR] vs. LuTx 74.5 months [45-118 IQR]; P = 0.44). Tetanus and diphtheria immunizations are recommended for LuTx patients to reduce the risk of infection. Because the LuTx group has lower antibody concentrations, further studies should investigate the possible need for more frequent tetanus and diphtheria boosters. © 2014 John Wiley & Sons A/S.

    There are limited data about the effect of metformin use on serum Vitamin B12 levels in type 2 diabetes patients from India. We studied serum Vitamin B12 levels in patients with type 2 diabetes mellitus who were receiving metformin and compared them to those never treated with metformin. A total of 183 patients ("metformin" group 121, "no metformin" group 63) of type 2 diabetes from the endocrinology clinic of a tertiary care center in North India were studied. Serum Vitamin B12 levels were measured in all patients. Diabetic neuropathy symptom score (DNS) and diabetic neuropathy examination score (DNE) were used to assess peripheral neuropathy while hemoglobin and mean corpuscular volume (MCV) were used to assess anemia. The serum Vitamin B12 levels were 267.7 ± 194.4 pmol/l in metformin group and 275.1 ± 197.2 pmol/l in the no metformin group ( P = 0.78). When adjusted for duration of diabetes, metformin use was associated with a 87.7 ± 37.7 pmol/l (95% confidence interval [CI], -162.1--3.3, P = 0.02) lower serum Vitamin B12 levels. No significant increase in the prevalence of neuropathy (DNS and DNE scores), anemia, or MCV was found in the Vitamin B12 deficient patients (levels <150 pmol/l) as compared to patients with normal Vitamin B12. However, serum Vitamin B12 levels for the entire cohort were higher by 12.2 ± 3.0 pmol/l (95% CI 6.4-18.0, P < 0.001) for every 1 year increase in the duration of diabetes. Metformin use was associated with a lower serum Vitamin B12 levels when adjusted for duration of diabetes. Increasing duration of diabetes was associated with higher serum Vitamin B12 levels.

    The aim of this study is to compare calculated free testosterone (cFT) and total testosterone (T) in predicting late-onset hypogonadism (LOH) in middle-aged and elderly males. We surveyed a random sample of 608 males between the ages of 45 and 87 years from Shanghai, China. The Aging Male Symptoms (AMS) questionnaire and the Androgen Deficiency in Aging Male (ADAM) questionnaire were completed by the subjects. Testosterone (T), sex hormone-binding globulin (SHBG), albumin, and other blood biochemical indexes were measured in 332 males. The corresponding cFT was obtained using the Vermeulen formula and the correlations between T and cFT were analyzed by SPSS statistical software. Among the 332 males who underwent biochemical evaluation, 289 males (87.0%) was positively screened by the ADAM questionnaire and 232 males (69.9%) by the AMS questionnaire. As suggested by linear regression, cFT exhibited a negative correlation with age in both ADAM+ and AMS+ group, whereas T did not appear to have significant correlation with age. Besides, there were statistically significant differences in cFT (Pmales. © 2016 Wiley Periodicals, Inc.

    Full Text Available Abstract Background Existent biomechanical studies on hip osteoarthritic gait have primarily focused on the end stage of disease. Consequently, there is no clear consensus on which specific gait parameters are of most relevance for hip osteoarthritis patients with mild to moderate symptoms. The purpose of this study was to explore sagittal plane gait characteristics during the stance phase of gait in hip osteoarthritis patients not eligible for hip replacement surgery. First, compared to healthy controls, and second, when categorized into two subgroups of radiographic severity defined from a minimal joint space of ≤/>2 mm. Methods Sagittal plane kinematics and kinetics of the hip, knee and ankle joint were calculated for total joint excursion throughout the stance phase, as well as from the specific events initial contact, midstance, peak hip extension and toe-off following 3D gait analysis. In addition, the Western Ontario and McMaster Universities Osteoarthritis Index, passive hip range of motion, and isokinetic muscle strength of hip and knee flexion and extension were included as secondary outcomes. Data were checked for normality and differences evaluated with the independent Student’s t-test, Welch’s t-test and the independent Mann–Whitney U-test. A binary logistic regression model was used in order to control for velocity in key variables. Results Fourty-eight hip osteoarthritis patients and 22 controls were included in the final material. The patients walked significantly slower than the controls (p=0.002, revealed significantly reduced joint excursions of the hip (pp=0.011, and a reduced hip flexion moment at midstance and peak hip extension (p2 mm suggested that the observed deviations were more pronounced in patients with greater radiographic severity. The biomechanical differences were, however, not reflected in self-reported symptoms or function. Conclusions Reduced gait velocity, reduced sagittal plane joint excursion, and

    Full Text Available Abstract Background The aim of this study was to investigate potential associations between gender equality at work and self-rated health. Methods 2861 employees in 21 companies were invited to participate in a survey. The mean response rate was 49.2%. The questionnaire contained 65 questions, mainly on gender equality and health. Two logistic regression analyses were conducted to assess associations between (i self-rated health and a register-based company gender equality index (OGGI, and (ii self-rated health and self-rated gender equality at work. Results Even though no association was found between the OGGI and health, women who rated their company as “completely equal” or “quite equal” had higher odds of reporting “good health” compared to women who perceived their company as “not equal” (OR = 2.8, 95% confidence interval = 1.4 – 5.5 and OR = 2.73, 95% CI = 1.6-4.6. Although not statistically significant, we observed the same trends in men. The results were adjusted for age, highest education level, income, full or part-time employment, and type of company based on the OGGI. Conclusions No association was found between gender equality in companies, measured by register-based index (OGGI, and health. However, perceived gender equality at work positively affected women’s self-rated health but not men’s. Further investigations are necessary to determine whether the results are fully credible given the contemporary health patterns and positions in the labour market of women and men or whether the results are driven by selection patterns.

    This paper examines the association between gestational diabetes mellitus and costs of care during pregnancy and 2-5 years post pregnancy. Healthcare utilization during pregnancy was measured for a sample of 658 women drawn from the Atlantic Diabetes in Pregnancy (ATLANTIC DIP) network. Healthcare utilization 2-5 years post pregnancy was assessed for a subsample of 348 women via a postal questionnaire. A vector of unit costs was applied to healthcare activity to calculate the costs of care at both time points. Differences in cost for women with gestational diabetes mellitus compared with those with normal glucose tolerance during the pregnancy were examined using univariate and multivariate regression analyses. Gestational diabetes mellitus was independently associated with an additional €817.60 during pregnancy (€1192.1 in the gestational diabetes mellitus group, €511.6 in the normal glucose tolerance group), in the form of additional delivery and neonatal care costs, and an additional €680.50 in annual healthcare costs 2-5 years after the index pregnancy (€6252.4 in the gestational diabetes mellitus group, €5434.8 in the normal glucose tolerance group). These results suggest that gestational diabetes mellitus is associated with increased costs of care during and post pregnancy. They provide indication of the associated cost that can be avoided or reduced by the screening, prevention and management of gestational diabetes mellitus in pregnancy. These estimates are useful for further studies that examine the cost and cost-effectiveness of such programmes. © 2014 The Authors. Diabetic Medicine © 2014 Diabetes UK.

    The objective of this study is to compare different methods for measuring breast density, both visual assessments and automated volumetric density, in a breast cancer screening setting. These measures could potentially be implemented in future screening programmes, in the context of personalised screening or screening evaluation. Digital mammographic exams (N = 992) of women participating in the Dutch breast cancer screening programme (age 50-75y) in 2013 were included. Breast density was measured in three different ways: BI-RADS density (5th edition) and with two commercially available automated software programs (Quantra and Volpara volumetric density). BI-RADS density (ordinal scale) was assessed by three radiologists. Quantra (v1.3) and Volpara (v1.5.0) provide continuous estimates. Different comparison methods were used, including Bland-Altman plots and correlation coefficients (e.g., intraclass correlation coefficient [ICC]). Based on the BI-RADS classification, 40.8% of the women had 'heterogeneously or extremely dense' breasts. The median volumetric percent density was 12.1% (IQR: 9.6-16.5) for Quantra, which was higher than the Volpara estimate (median 6.6%, IQR: 4.4-10.9). The mean difference between Quantra and Volpara was 5.19% (95% CI: 5.04-5.34) (ICC: 0.64). There was a clear increase in volumetric percent dense volume as BI-RADS density increased. The highest accuracy for predicting the presence of BI-RADS c+d (heterogeneously or extremely dense) was observed with a cut-off value of 8.0% for Volpara and 13.8% for Quantra. Although there was no perfect agreement, there appeared to be a strong association between all three measures. Both volumetric density measures seem to be usable in breast cancer screening programmes, provided that the required data flow can be realized.

Further investigations are necessary to determine whether the results are fully credible given the contemporary health patterns and positions in the labour market of women and men or whether the results are driven by selection patterns.

    Objectives: Atrial fibrillation (AF) is a common cardiac arrhythmia with increased risk of thromboembolic stroke. Oral anticoagulation (OAC) reduces stroke risk by up to 68%. The aim of our study was to evaluate quality of care in patients with AF in a primary health care setting with a focus on physician guideline adherence for OAC prescription and heart rate- and rhythm management. In a second step we aimed to compare OAC rates based on primary care data with rates based on claims data. Methods: We included all GP practices in the region Vorpommern-Greifswald, Germany, which were willing to participate (N=29/182, response rate 16%). Claims data was derived from the regional association of statutory health insurance physicians. Patients with a documented AF diagnosis (ICD-10-GM-Code ICD I48.-) from 07/2011-06/2012 were identified using electronic medical records (EMR) and claims data. Stroke and bleeding risk were calculated using the CHA 2 DS 2 -VASc and HAS-BLED scores. We calculated crude treatment rates for OAC, rate and rhythm control medications and adjusted OAC treatment rates based on practice and claims data. Adjusted rates were calculated including the CHA 2 DS 2 -VASc and HAS-BLED scores and individual factors affecting guideline based treatment. Results: We identified 927 patients based on EMR and 1,247 patients based on claims data. The crude total OAC treatment rate was 69% based on EMR and 61% based on claims data. The adjusted OAC treatment rates were 90% for patients based on EMR and 63% based on claims data. 82% of the AF patients received a treatment for rate control and 12% a treatment for rhythm control. The most common reasons for non-prescription of OAC were an increased risk of falling, dementia and increased bleeding risk. Conclusion: Our results suggest that a high rate of AF patients receive a drug therapy according to guidelines. There is a large difference between crude and adjusted OAC treatment rates. This is due to individual

    Full Text Available ABSTRACT Objective: Compare the maximal isokinetic muscle strength of knee extensor and flexor muscles between patients with knee osteoarthritis and patients submitted to total knee arthroplasty. Methods: Volunteers were divided into five groups (n = 20: Control; Ahlbäck I and II; Ahlbäck IV; six months after total knee arthroplasty; 12 months after total knee arthroplasty. An isokinetic knee strength evaluation was conducted for the quadriceps and hamstrings at 60°/s. Results: Significant differences in the peak torque of the quadriceps and hamstrings were found among the groups (p < 0.001. The Ahlbäck IV, six-month, and 12-month postoperative groups demonstrated lower values when compared to the Control and Ahlbäck I and II groups. When percentage values were compared to the Control group, mean differences ranged from 7% to 41%. Conclusion: Patients with healthy knees or early stage osteoarthritis have higher quadriceps and hamstrings strengths than those with a more advanced stage of the disease, even after knee replacement. These findings suggest that the traditional rehabilitation programs do not recover strength to levels observed in individuals without knee osteoarthritis.

    Full Text Available Abstract Background Idiopathic pulmonary arterial hypertension (IPAH is a progressive and still incurable disease. Research of IPAH-pathogenesis is complicated by the lack of a direct access to the involved tissue, the human pulmonary vasculature. Various auto-antibodies have been described in the blood of patients with IPAH. The purpose of the present work was therefore to comparatively analyze peripheral blood B lymphocyte RNA expression characteristics in IPAH and healthy controls. Methods Patients were diagnosed having IPAH according to WHO (mean pulmonary arterial pressure ≥ 25 mmHg, pulmonary capillary occlusion pressure ≤ 15 mmHg, absence of another explaining disease. Peripheral blood B-lymphocytes of patients and controls were immediately separated by density gradient centrifugation and magnetic beads for CD19. RNA was thereafter extracted and analyzed by the use of a high sensitivity gene chip (Affymetrix HG-U133-Plus2 able to analyze 47000 transcripts and variants of human genes. The array data were analyzed by two different softwares, and up-and down-regulations were defined as at least 1.3 fold with standard deviations smaller than fold-changes. Results Highly purified B-cells of 5 patients with IPAH (mean pulmonary artery pressure 51 ± 13 mmHg and 5 controls were analyzed. Using the two different analyzing methods we found 225 respectively 128 transcripts which were up-regulated (1.3–30.7 fold in IPAH compared with healthy controls. Combining both methods, there were 33 overlapping up-regulated transcripts and no down-regulated B-cell transcripts. Conclusion Patients with IPAH have a distinct RNA expression profile of their peripheral blood B-lymphocytes compared to healthy controls with some clearly up-regulated genes. Our finding suggests that in IPAH patients B cells are activated.

    Full Text Available Abstract Background In 2005, Pakistan was first labeled as a country with concentrated epidemic of Human Immunodeficiency Virus (HIV. This was revealed through second generation surveillance conducted by HIV/AIDS Surveillance Project (HASP. While injection drug users (IDUs were driving the epidemic, subsequent surveys showed that Hijra (transgender sex workers (HSWs were emerging as the second most vulnerable group with an average national prevalence of 6.4%. An exceptionally high prevalence (27.6% was found in Larkana, which is a small town on the right bank of river Indus near the ruins of Mohenjo-Daro in the province of Sindh. This paper presents the risk factors associated with high prevalence of HIV among HSWs in Larkana as compared to other cities of the country. Methods Data were extracted for secondary analysis from 2008 Integrated behavioral and biological survey (IBBS to compare HSWs living in Larkana with those living in other cities including Karachi and Hyderabad in Sindh; Lahore and Faisalabad in Punjab; and Peshawar in Khyber Pakhtunkhwa provinces. After descriptive analysis, univariate and multivariate analyses were performed to identify risk factors. P value of 0.25 or less was used to include factors in multivariate analysis. Results We compared 199 HSWs from Larkana with 420 HSWs from other cities. The average age of HSWs in Larkana was 26.42 (±5.4 years. Majority were Sindhi speaking (80%, uneducated (68% and unmarried (97%. In univariate analysis, factors associated with higher prevalence of HIV in Larkana included younger age i.e. 20–24 years (OR: 5.8, CI: 2.809–12.15, being unmarried (OR: 2.4, CI: 1.0–5.7, sex work as the only mode of income (OR: 5.5, CI: 3.70–8.2 and longer duration of being involved in sex work 5–10 years (OR: 3.3, CI: 1.7–6.12. In multivariate logistic regression the HSWs from Larkana were more likely to lack knowledge regarding preventive measures against HIV (OR 11.9, CI: 3.4–41.08 and

    Full Text Available This study analyzed the impact of area residential property values, an objective measure of socioeconomic status (SES, on self-rated health (SRH in Seattle, Washington and Paris, France. This study brings forth a valuable comparison of SRH between cities that have contrasting urban forms, population compositions, residential segregation, food systems and transportation modes. The SOS (Seattle Obesity Study was based on a representative sample of 1394 adult residents of Seattle and King County in the United States. The RECORD Study (Residential Environment and Coronary Heart Disease was based on 7131 adult residents of Paris and its suburbs in France. Socio-demographics, SRH and body weights were obtained from telephone surveys (SOS and in-person interviews (RECORD. All home addresses were geocoded using ArcGIS 9.3.1 (ESRI, Redlands, CA. Residential property values were obtained from tax records (Seattle and from real estate sales (Paris. Binary logistic regression models were used to test the associations among demographic and SES variables and SRH. Higher area property values significantly associated with better SRH, adjusting for age, gender, individual education, incomes, and BMI. The associations were significant for both cities. A one-unit increase in body mass index (BMI was more detrimental to SRH in Seattle than in Paris. In both cities, higher area residential property values were related to a significantly lower obesity risk and better SRH. Ranked residential property values can be useful for health and weight studies, including those involving social inequalities and cross-country comparisons.

    Full Text Available Introduction: Teeth play various functional and esthetic roles. As any part of the body, even teeth loss gives one the feeling of being handicapped showing a negative impact on emotions. Sometimes, few people think that having 32 teeth and losing a few among them will not make a difference. Aim: To assess and compare the emotional effects due to loss of natural teeth in complete denture wearers and nondenture wearers. Materials and Methods: A hospital-based survey was conducted on complete denture wearers and nondenture wearers who were attending the outpatient department in a dental hospital for 2 months using a pretested, self-administered questionnaire. Results: Among them who were surveyed, 65.75% agreed accepting the tooth loss is difficult, only 30.13% felt that loss of teeth affected their self-confidence (P = 0.094, about 80.82% reported that natural teeth loss affected their eating efficiency, and 57.53% of them found it difficult while speaking to others. There was a significant difference between denture wearers and nondenture wearers when asked whether loss of teeth affected their looks, eating efficiency, and speaking difficulties (P = 0.000. Conclusion: Even though the majority of them found it difficult in accepting tooth loss, it did not affect their self-confidence majorly; however, most of them found functional difficulties with loss of natural teeth.

    Full Text Available Lumbar spinal stenosis (LSS is common in the elderly. However, there have been few reports on its impact on quality of life (QoL in community-dwelling individuals. The purpose of this study was to clarify how symptomatic LSS affects QoL at the community level. A total of 1862 people (697 males and 1165 females, most subjects were between 40 and 85 y.o. agreed to participate and were interviewed. The presence of symptomatic LSS was assessed by a specially designed questionnaire. The Medical Outcomes Study 36-Item Short Form Health Survey (SF-36 was also administered. In addition, the presence of comorbid conditions that affect QoL, such as osteoarthritis of the knee and hip, cardiovascular disease, cerebrovascular disease, or respiratory disease, was also analyzed. The prevalence of symptomatic LSS gradually increased with age. Furthermore, the presence of symptomatic LSS had a strong negative effect on all 8 physical and mental domains and the physical component summary (PCS (OR: 1.547–2.544 but not the mental component summary (MCS. In comparison with comorbid conditions, LSS had a much stronger negative impact on health-related QoL (HR-QoL. The current study confirmed that the presence of symptomatic LSS might have a strong negative influence on HR-QoL in the community setting.

    Full Text Available Abstract Background Toxoplasmosis in immuno-compromised hosts manifests primarily as a life threatening condition, toxoplasmic encephalitis. However, there is scarce information about the magnitude of Toxoplasma gondii infection among HIV-infected people in Ethiopia. This study was, therefore, conducted to determine the sero-prevalence of T. gondii infection among HIV-infected and HIV-uninfected subjects. Findings Sera were collected from people with and without HIV infection for the purpose of studying hepatitis B virus (HBV at St. Paul Hospital, Addis Ababa, Ethiopia from 24 January 2007 to 15 February 2007. Among these sera, the first 330 consecutive sera, 165 from each HIV sero-group, were selected and tested for anti-T. gondii IgG antibodies using Enzyme Linked Immunosorbent Assay. The seroprevalence of Toxoplasma infection was assessed against socio-demographic characteristics, HIV and HBV serostatus and HBV-related risk factors. The overall sero-prevalence of latent T. gondii infection among the study subjects was 90.0%. Toxoplasma infection was observed with respective prevalence of 93.3% and 86.7% among HIV-infected and HIV-uninfected people. Though Toxoplasma infection seems to be influenced by age, gender and HIV serostatus, only HBV serostatus was significantly associated (OR 2.71, CI 1.12 to 6.57 in multivariate logistic regression analysis. Conclusion The seroprevalence of latent T. gondii infection is high and similar by HIV status. Educating people to prevent acquisition of new Toxoplasma infection and minimizing the risk of disease manifestations among HIV-Toxoplasma co-infected individuals is important.

    Full Text Available Rheumatoid arthritis (RA has been identified as an independent cardiovascular risk factor. The importance of risk factors such as hypertension and hyperlipidemia in the generation of atherosclerosis in RA patients is unclear. This study analyzed clinical parameters associated with carotid intima media thickness (cIMT in patients with RA.Subjects with RA and healthy controls without RA, both without known cardiovascular disease, were included. Participants underwent a standard physical examination and laboratory measurements including a lipid profile. cIMT was measured semi-automatically by ultrasound.In total 243 RA patients and 117 controls were included. The median RA disease duration was 7 years (IQR 2-14 years. The median DAS28 was 2.4 (IQR 1.6-3.2 and 114 (50.4% of the RA patients were in remission. The presence of RA and cIMT were not associated (univariate analysis. Multivariable regression analysis showed that cIMT in RA patients was associated with age (B = 0.006, P<0.001 and systolic blood pressure (B = 0.003, P = 0.003. In controls, cIMT was associated with age (B = 0.006, P<0.001 and smoking (B = 0.097, P = 0.001.cIMT values were similar between RA patients and controls. Hypertension was strongly associated with cIMT in RA patients. After adjustment, no association between cIMT and specific RA disease characteristics was found in this well treated RA cohort.

    Decision makers are searching for models to redesign home care and to organize health care in a more sustainable way. The aim of this study is to identify and characterize home care models within and across European countries by means of structural characteristics and care processes at the policy and the organization level. At the policy level, variables that reflected variation in health care policy were included based on a literature review on the home care policy for older persons in six European countries: Belgium, Finland, Germany, Iceland, Italy, and the Netherlands. At the organizational level, data on the structural characteristics and the care processes were collected from 36 home care organizations by means of a survey. Data were collected between 2013 and 2015 during the IBenC project. An observational, cross sectional, quantitative design was used. The analyses consisted of a principal component analysis followed by a hierarchical cluster analysis. Fifteen variables at the organizational level, spread across three components, explained 75.4% of the total variance. The three components made it possible to distribute home care organizations into six care models that differ on the level of patient-centered care delivery, the availability of specialized care professionals, and the level of monitoring care performance. Policy level variables did not contribute to distinguishing between home care models. Six home care models were identified and characterized. These models can be used to describe best practices.

    Full Text Available Nuclear fusion may be among the strongest sustainable ways to replace fossil fuels because it does not contribute to acid rain or global warming. In this context, activated cobalt materials in corrosion products for fusion energy are significant in determination of dose levels during maintenance after a coolant leak in a nuclear fusion reactor. Therefore, cross-section studies on cobalt material are very important for fusion reactor design. In this article, the excitation functions of some nuclear reaction channels induced by proton particles on 59Co structural material were predicted using different models. The nuclear level densities were calculated using different choices of available level density models in ALICE/ASH code. Finally, the newly calculated cross sections for the investigated nuclear reactions are compared with the experimental values and TENDL data based on TALYS nuclear code.

Methods: This cross-sectional study took place between April 2014 and April 2015 among 3,870 patients referred to the Toxicology Emergency Department of Baharlou Hospital, Tehran University of Medical Sciences, Tehran, Iran. Those with clinical signs of drug abuse and positive urine screening tests were included in the study, while cases of chronic abuse were excluded. Cardiac complications were evaluated via electrocardiography (ECG and transthoracic echocardiography. Results: A total of 230 patients (5.9% had a history of acute amphetamine abuse and positive urine tests. Of these, 32 patients (13.9% were <20 years old and 196 (85.2% were male. In total, 119 (51.7% used amphetamine and methamphetamine compounds while 111 (48.3% used amphetamines with morphine or benzodiazepines. The most common ECG finding was sinus tachycardia (43.0%, followed by sinus tachycardia plus a prolonged QT interval (34.3%. Mean creatine kinase-MB and troponin I levels were 35.9 ± 4.3 U/mL and 0.6 ± 0.2 ng/mL, respectively. A total of 60 patients (26.1% were admitted to the Intensive Care Unit. The majority (83.3% of these patients had normal echocardiography results. The mean aortic root diameter (ARD was 27.2 ± 2.8 mm. Abnormalities related to the ARD were found in 10 patients (16.7%, three of whom subsequently died. Conclusion: According to these findings, cardiac complications were common among Iranian patients who abuse amphetamines, although the majority of patients had normal echocardiography and ECG findings.

    Health maintenance and promotion are the fundamental prerequisites to community development. The best time for establishing healthy lifestyle habits is during adolescence. Due to importance of health promotion behaviors in adolescents, this study was conducted to investigate health-promoting behaviors and its associated factors among high school students in Rasht, Iran. A cross-sectional descriptive study was conducted on 424 students during the first semester of the year 2012. We employed the multistage sampling design to recruit from private and public high schools in Rasht, Iran. The data collection instrument was a self-report questionnaire consisting of two parts. The first part of instrument was consisted of demographic questionnaire and the second part was adolescent health promotion scale (AHPS) questionnaire. AHPS questionnaire was consisted of six dimensions (nutrition, social support, health responsibility, life appreciation, physical activity, and stress management) to measure health promoting lifestyles. Statistical analysis was performed by SPSS 16 software employing ANOVA (analysis of variance) test, t-test, Mann-Whitney, and the Kruskal-Wallis. The score of total Adolescent Health Promotion Scale were 3.58 ± 0.52 (possible range was 1-5). The highest score was in life appreciation dimension (3.99 ± 0.068) and the lowest score was in health responsibility dimension. Moreover, Significant associations were found between the adolescent health promotion Scale with age (P school grade (P health instructors, schoolteachers, and families must pay more attention to these students. Moreover, as most of lifelong healthy and unhealthy lifestyle habits are established during adolescence, developing effective health promotion and disease prevention strategies for adolescents seems crucial.

    the many applications of Monte Carlo modelling in nuclear medicine imaging make it desirable to increase the accuracy and computational speed of Monte Carlo codes. The accuracy of Monte Carlo simulations strongly depends on the accuracy in the probability functions and thus on the cross section libraries used for photon transport calculations. A comparison between different photon cross section libraries and parametrizations implemented in Monte Carlo simulation packages developed for positron emission tomography and the most recent Evaluated Photon Data Library (EPDL97) developed by the Lawrence Livermore National Laboratory was performed for several human tissues and common detector materials for energies from 1 keV to 1 MeV. Different photon cross section libraries and parametrizations show quite large variations as compared to the EPDL97 coefficients. This latter library is more accurate and was carefully designed in the form of look-up tables providing efficient data storage, access, and management. Toge...

    2014-01-01

    Background Lifestyle factors have been associated mostly with individual chronic diseases. We investigated the relationship between lifestyle factors (individual and combined) and the co-occurrence of multiple chronic diseases. Methods Cross-sectional analysis of results from the Program of Research on the Evolution of a Cohort Investigating Health System Effects (PRECISE) in Quebec, Canada. Subjects aged 45 years and older. A randomly-selected cohort in the general population recruited by telephone. Multimorbidity (3 or more chronic diseases) was measured by a simple count of self-reported chronic diseases from a list of 14. Five lifestyle factors (LFs) were evaluated: 1) smoking habit, 2) alcohol consumption, 3) fruit and vegetable consumption, 4) physical activity, and 5) body mass index (BMI). Each LF was given a score of 1 (unhealthy) if recommended behavioural targets were not achieved and 0 otherwise. The combined effect of unhealthy LFs (ULFs) was evaluated using the total sum of scores. Results A total of 1,196 subjects were analyzed. Mean number of ULFs was 2.6 ± 1.1 SD. When ULFs were considered separately, there was an increased likelihood of multimorbidity with low or high BMI [Odd ratio (95% Confidence Interval): men, 1.96 (1.11-3.46); women, 2.57 (1.65-4.00)], and present or past smoker [men, 3.16 (1.74-5.73)]. When combined, in men, 4-5 ULFs increased the likelihood of multimorbidity [5.23 (1.70-16.1)]; in women, starting from a threshold of 2 ULFs [1.95 (1.05-3.62)], accumulating more ULFs progressively increased the likelihood of multimorbidity. Conclusions The present study provides support to the association of lifestyle factors and multimorbidity. PMID:24996220

    To investigate the baseline status of patients' awareness, knowledge, and attitudes to patient safety in China, and to determine the factors that influence patients' involvement in patient safety. We conducted a cross sectional survey using questionnaires adapted from recent studies on patient safety from outside China. The items included medical errors, infection, medication safety, and other aspects of patient safety. The questionnaire included 17 items and 5 domains. The survey was conducted between Jan. 2009 and Dec. 2010 involving 1000 patients from ten grade-A hospitals in seven provinces or cities in China. Most patients from the surgery departments completed the questionnaires voluntarily and anonymously. Five reviewers independently input the data into Microsoft Excel 2003, and the data were double-checked. Data were analyzed using SPSS 15.0 software for differences in the perceptions and attitudes of patients toward patient safety among different genders, ages, and regions. We distributed 1000 questionnaires and collected 959 completed questionnaires (response rate: 96%). Among the respondents, 58% of patients did not know what medical error is. Sixty-five percent of patients wanted disclosure of all medical errors. After errors occurred, 58% of patients wanted explanations of all possible harms that had resulted. Among 187 patients who had experienced medical errors, 83% of patients had sought appropriate legal action. About 52% of patients understood hospital infection, but 28% patients did not know that infections could occur in hospital. Seventy-eight percent of patients thought that medical staff should wash their hands before examining patients. More than half of the patients (68%) were willing to remind the staff of hygiene if they saw unsanitary conditions in a health clinic. Only 14% of patients knew the side effects of medications that they took. The majority of patients surveyed expressed willingness to contribute to patient safety, but their

    Workplace violence is a serious problem for clinical nurses, as it leads to a series of adverse consequences. However, little information is available on the prevalence and influencing factors of workplace violence in China. To determine the prevalence of workplace violence against Chinese nurses, and its influencing factors. A multi-center, cross-sectional study. The seven geographical regions (i.e., northeast, north, central, east, south, northwest, and southwest) of China. Four thousand one hundred and twenty-five nurses. We randomly selected 28 hospitals, located in 14 cities over 13 provinces across the seven geographical regions. We distributed 4125 questionnaires between May 4 and September 23, 2014. The questionnaire included demographic information, the Workplace Violent Incident Questionnaire, the Jefferson Scale of Empathy-Health Professionals, and the Practice Environment Scale of Nursing Work Index. Workplace violence was assessed in terms of physical violence, non-physical violence, sexual harassment, and organized healthcare disturbances. We then performed descriptive analyses and logistic regressions on the collected data. The response rate was 92.97% (n=3835). Additionally, we obtained valid questionnaires from 3004 individuals. Of these, 25.77% reported experiencing physical violence, 63.65% non-physical violence, 2.76% sexual harassment, and 11.72% organized healthcare disturbances. A logistic regression analysis revealed that nurses who have less experience, work a rotating roster, work in emergency rooms and pediatrics departments, have low empathy levels, and who work in poor nursing environments have greater odds of experiencing violence. Experiences of workplace violence are prevalent among Chinese nurses, and several complex factors are associated with a greater risk of such violence, including nurses' personal characteristics, work settings, and work environments. Our results might help nursing managers understand their employees' work

    Neutron induced fission and total cross sections of 234 U have been measured over the neutron energy range from a few eV to several MeV. Neutron and fission widths for 118 cross section resonances below 1500 eV have been determined and give a class I level spacing of 10.64 + -0.46 eV and a neutron strength function of (0.857 +- 0.108)x10 -4 . These fine structure resonances comprise a narrow intermediate structure resonance in the sub-threshold fission cross section of 234 U. Parameters for the Lorentzian energy dependence of the mean fission width are deduced on the assumption that, relative to this mean, the observed fission widths have a Porter-Thomas distribution. Two large fission widths measured for resonances at 1092.5 eV and 1134 eV may indicate the presence of a second narrow intermediate structure resonance at about this energy. The class II level spacing derived from the observation of 7 resonances below 13 keV is 2.1 +-0.3 keV. Pronounced breaks in the fission cross section at 310 keV, 550 keV and 720 keV are assumed to be due to β-vibrational levels in the second minimum of the Strutinsky potential. Fluctuations due to the presence of class II resonances are strongly evident for each of these vibrational levels. It is shown that the fluctuations near 310 keV are consistent with parameters deduced from the low energy data and this enables parameters for the double humped fission barrier potential to be obtained

    Full Text Available AIM To study the changes in phosphate metabolism in kidney donors, to study the correlation of albuminuria, fractional excretion of phosphorus [FE Pi] and estimated glomerular filtration rate [eGFR] with fibroblast growth factor 23 [FGF 23] in kidney donors, to study the early tubule interstitial injury in the remnant kidney of donors by measuring urine transforming growth factor beta [TGF beta] levels. MATERIALS AND METHODS A cross-sectional study in which kidney donors with 1 year or more after donation were included. 69 kidney donors with a mean duration of 5.86 years after kidney donation were studied. Serum phosphate level, fractional excretion of phosphorus [FE Pi] and serum levels of parathyroid hormone were measured. Plasma levels of FGF 23 were measured by a second generation enzyme linked immune sorbent assay [ELISA]. Renal function was assessed by estimated glomerular filtration rate [eGFR] and degree of albuminuria. Urine levels of transforming growth factor beta [TGF beta] were measured by ELISA. A hypothesis that in kidney donors with reduced nephron number, the single nephron excretion of phosphorus will be increased to maintain normal phosphorus homeostasis and that this increase in single nephron phosphorus excretion may be mediated by FGF 23 was proposed. Testing of this hypothesis was done by studying the correlation between parameters of phosphorus metabolism, FGF 23 and the renal function of the donors. RESULTS The mean eGFR was 70.36 mL/min/1.73 m2 . 52.2% of donors had moderate increase in albuminuria [microalbuminuria], Serum phosphorus, fractional excretion of phosphorus and serum PTH levels were in the normal range. FGF 23 levels were in the normal reference range and showed no correlation with FE pi, eGFR or albuminuria, Urine TGF-beta levels were undetectable in all the donors. DISCUSSION Normal phosphorus homeostasis is maintained in kidney donors. There was no correlation between FE pi and FGF 23 levels. Kidney

    An essential model is performed - an independent study of the internal coherence between high-energy total cross-section data by using classes of functions satisfying general principles. The study is practically independent of the ρ-parameter values. This general analysis, made without any fit, reveals certain inconsistencies in the existing set of high-energy data. Some of these inconsistencies are eliminated by giving up arbitrary assumptions sometimes made in 'fitology'. It is shown that the ln 2 s increase of total cross-sections at high energies is clearly favoured when compared with other possible behaviours. (authors). 16 refs., 3 figs

    Overweight in cats is a major risk factor for diabetes mellitus and has also been associated with other disorders. Overweight and obesity are believed to be increasing problems in cats, as is currently seen in people, with important health consequences. The objectives of the present study were to determine the prevalence of overweight in cats from two different cohorts in a cross-sectional study design and to assess associations between overweight and diagnoses, and between overweight and demographic and environmental factors. Data were obtained from medical records for cats (n = 1072) visiting an academic medical center during 2013-2015, and from a questionnaire on insured cats (n = 1665). From the medical records, information on body condition score, breed, age, sex, neutering status, and diagnosis was obtained. The questionnaire included questions relating to the cat's body condition, breed, age, sex, neutering status, outdoor access, activity level, and diet. Data were analyzed by multivariable logistic regression. The prevalence of overweight was 45% in the medical records cohort and 22% in the questionnaire cohort, where owners judged their pet's body condition. Overweight cats in the medical records cohort were more likely to be diagnosed with lower urinary tract disease, diabetes mellitus, respiratory disease, skin disorders, locomotor disease, and trauma. Eating predominantly dry food, being a greedy eater, and inactivity were factors associated with an increased risk of overweight in the final model in the questionnaire cohort. In both cohorts, the Birman and Persian breeds, and geriatric cats, were less likely to be overweight, and male cats were more likely to be overweight. The prevalence of overweight cats (45%) as assessed by trained personnel was high and in the same range as previously reported. Birman and Persian cats had a lower risk of overweight. The association with dry food found in adult, neutered cats is potentially important because

    Paper questionnaires have traditionally been the first choice for data collection in research. However, declining response rates over the past decade have increased the risk of selection bias in cross-sectional studies. The growing use of the Internet offers new ways of collecting data, but trials using Web-based questionnaires have so far seen mixed results. A secure, online digital mailbox (e-Boks) linked to a civil registration number became mandatory for all Danish citizens in 2014 (exemption granted only in extraordinary cases). Approximately 89% of the Danish population have a digital mailbox, which is used for correspondence with public authorities. We aimed to compare response rates, completeness of data, and financial costs for different invitation methods: traditional surface mail and digital mail. We designed a cross-sectional comparative study. An invitation to participate in a survey on help-seeking behavior in out-of-hours care was sent to two groups of randomly selected citizens from age groups 30-39 and 50-59 years and parents to those aged 0-4 years using either traditional surface mail (paper group) or digital mail sent to a secure online mailbox (digital group). Costs per respondent were measured by adding up all costs for handling, dispatch, printing, and work salary and then dividing the total figure by the number of respondents. Data completeness was assessed by comparing the number of missing values between the two methods. Socioeconomic variables (age, gender, family income, education duration, immigrant status, and job status) were compared both between respondents and nonrespondents and within these groups to evaluate the degree of selection bias. A total 3600 citizens were invited in each group; 1303 (36.29%) responded to the digital invitation and 1653 (45.99%) to the paper invitation (difference 9.66%, 95% CI 7.40-11.92). The costs were €1.51 per respondent for the digital group and €15.67 for paper group respondents. Paper

    For understanding the reaction mechanism of heavy compound nucleus (CN), the study of evaporation residue (ER) cross-section plays a vital role. For heavier systems, the probability of formation of CN is strongly influenced by the properties of the di-nuclear system at contact configuration, where entrance channel plays a major role in reaction dynamics. Nuclear structure of the colliding nuclei also plays a key role, which influence the fusion probability. In some of the recent studies the dependence of the fusion reaction on the nuclear shell structure of projectile and target nuclei was also investigated and the importance of N = 82 in the heavy ion fusion reaction was proposed. It was reported that shell closure of one of the interacting nuclei can lead to the enhanced ER cross-section and helps in the synthesis of heavy nuclei. Keeping these points in mind, a systematic measurement of ER cross sections for 48 Ti + 140,142 Ce, 124 Sn systems was performed. Here, 140 Ce target is neutron shell closed (N T =82) but 142 Ce have 84 neutrons. By comparing the ER cross-sections of these systems, the effect of neutron shell closure on fusion probability can be examined. The ER excitation function for third system ( 48 Ti + 124 Sn) was also measured at few energy points to estimate the transmission efficiency of the spectrometer

    Reaction cross sections (σ R ) for the neutron-rich nucleus 14 B on Be, C, and Al targets have been measured at several energies in the intermediate energy range of 45-120 MeV/nucleon. The present experimental σ R show a significant enhancement relative to the systematics of stable nuclei. The nucleon density distribution was deduced through the fitting procedure with the modified Glauber calculation. The necessity of a long tail in the density distribution was found, which is consistent with the valence neutron in 2s 1/2 orbital with the small empirical one-neutron separation energy in 14 B.

    To evaluate health-related quality of life (HRQoL) and self-esteem in patients with diabetic foot ulcers (DFUs), a cross-sectional, comparative study was conducted among 35 consecutive patients with diabetes mellitus (DM) attending outpatient clinics in Pouso Alegre, Brazil. Fifteen (15) patients with and 20 without a DFU participated in the study. Demographic variables were obtained and HRQoL and self-esteem were assessed using the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) and Rosenberg Self-Esteem Scale. In both groups, 80% of patients were women. Average age did not differ significantly between the DFU and control groups (average 56 [SD 8.42] and 52 years [SD 6.68], respectively) but disease duration was significantly longer (P Self-esteem scores were similar in both groups. The results of this study confirm that patient HRQoL is negatively affected by the presence of a DFU. Wound prevention programs for patients with DM may help reduce the scope of this problem while DFU treatment programs that include psychological support may improve patient QoL.

    In many countries midwives act as the main providers of care for women throughout pregnancy, labour and birth. In our large public teaching hospital in Australia we restructured the way midwifery care is offered and introduced caseload midwifery for one third of women booked at the hospital. We then compared the costs and birth outcomes associated with caseload midwifery compared to the two existing models of care, standard hospital care and private obstetric care. We undertook a cross sectional study examining the risk profile, birth outcomes and cost of care for women booked into one of the three available models of care in a tertiary teaching hospital in Australia between July 1st 2009 December 31st 2010. To control for differences in population or case mix we described the outcomes for a cohort of low risk first time mothers known as the 'standard primipara'. Amongst the 1,379 women defined as 'standard primipara' there were significant differences in birth outcome. These first time 'low risk' mothers who received caseload care were more likely to have a spontaneous onset of labour and an unassisted vaginal birth 58.5% in MGP compared to 48.2% for Standard hospital care and 30.8% with Private obstetric care (p 1590.91 less than Standard hospital care per woman (p women in the study who received caseload care. Cost reduction appears to be achieved through reorganising the way care is delivered in the public hospital system with the introduction of Midwifery Group Practice or caseload care. The study also highlights the unexplained clinical variation that exists between the three models of care in Australia.

    Full Text Available Abstract Background Being severely overweight is a distinctive clinical feature of Prader-Willi Syndrome (PWS. PWS is a complex multisystem disorder, representing the most common form of genetic obesity. The aim of this study was the analysis of the gait pattern of adult subjects with PWS by using three-Dimensional Gait Analysis. The results were compared with those obtained in a group of obese patients and in a group of healthy subjects. Methods Cross-sectional, comparative study: 19 patients with PWS (11 males and 8 females, age: 18–40 years, BMI: 29.3–50.3 kg/m2; 14 obese matched patients (5 males and 9 females, age: 18–40 years, BMI: 34.3–45.2 kg/m2; 20 healthy subjects (10 males and 10 females, age: 21–41 years, BMI: 19.3–25.4 kg/m2. Kinematic and kinetic parameters during walking were assessed by an optoelectronic system and two force platforms. Results PWS adult patients walked slower, had a shorter stride length, a lower cadence and a longer stance phase compared with both matched obese, and healthy subjects. Obese matched patients showed spatio-temporal parameters significantly different from healthy subjects. Furthermore, Range Of Motion (ROM at knee and ankle, and plantaflexor activity of PWS patients were significantly different between obese and healthy subjects. Obese subjects revealed kinematic and kinetic data similar to healthy subjects. Conclusion PWS subjects had a gait pattern significantly different from obese patients. Despite that, both groups had a similar BMI. We suggest that PWS gait abnormalities may be related to abnormalities in the development of motor skills in childhood, due to precocious obesity. A tailored rehabilitation program in early childhood of PWS patients could prevent gait pattern changes.

    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.

    People with mental illness experience high levels of morbidity and mortality from physical disease compared to the general population. Our primary aim was to compare how people with severe mental illness (SMI; i.e. schizophrenia-spectrum disorders and bipolar disorder) and non-psychotic mental illness perceive their: (i) global physical health, (ii) barriers to improving physical health, (iii) physical health with respect to important aspects of life and (iv) motivation to change modifiable high-risk behaviours associated with coronary heart disease. A secondary aim was to determine health locus of control in these two groups of participants. People with SMI and non-psychotic mental illness were recruited from an out-patient adult mental health service in London. Cross-sectional comparison between the two groups was conducted by means of a self-completed questionnaire. A total of 146 people participated in the study, 52 with SMI and 94 with non-psychotic mental illness. There was no statistical difference between the two groups with respect to the perception of global physical health. However, physical health was considered to be a less important priority in life by people with SMI (OR 0.5, 95% CI 0.2-0.9, p = 0.029). There was no difference between the two groups in their desire to change high risk behaviours. People with SMI are more likely to have a health locus of control determined by powerful others (p locus of control may provide a theoretical focus for clinical intervention in order to promote a much needed behavioural change in this marginalised group of people.

    Though HIV/AIDS has multidimensional consequences on quality of life, there is a gap in measuring and monitoring health related quality of life of HIV/AIDS patients. Hence, this study intended to measure health related quality of life domains and associated determinants among people living with HIV/AIDS in western Ethiopia. A comparative cross-sectional study was conducted among 520 HIV/AIDS patients on anti-retroviral therapy in public health facilities in West Shoa Zone, Western Ethiopia from April to May, 2016. Participants were selected using simple random sampling method. Quality of life was measured using WHOQOL-HIV BREF and depression was assessed using Beck Depression Inventory, Second Edition (BDI-II). Data were analyzed using SPSS version 22. An independent sample t-test was used to compare quality of life domains between men and women and logistic regression analysis was used to determine independent predictors. Females had significantly lower quality of life in physical, psychological, independence and environmental domains as compared with males except social relationship and spiritual domains. Depressed HIV patients had significantly lower quality of life in all domains as compared with HIV infected patients without depression in both genders. Malnutrition and anemia were significantly associated with poor physical, psychological, independence and environmental domains. Anemic women had 1.9 times lower independence quality of life compared with women who had no anemia (AOR = 1.9, 95%CI: 1.4, 3.5). Tuberculosis was also predictor of physical, psychological, independence and social domains in both genders. TB/HIV co-infected females had 2.0 times poorer environmental health compared to only HIV infected females (AOR = 2.0, 95%CI: 1.2, 3.5). Family support, education and occupation were also independent significant predictors of QOL domains in both genders. In females, residence was significantly associated with independence (AOR = 1.8, 95%CI

    To investigate the difference in attitudes: (1) between first and fourth year physiotherapy students towards functioning in individuals with back pain; and (2) between physiotherapy students and non-healthcare students towards functioning in individuals with back pain. Observational, cross-sectional study. Glasgow Caledonian University, Scotland, UK. First year physiotherapy (n=61) and non-healthcare students (n=61), and fourth year physiotherapy (n=62) and non-healthcare students (n=62). All participants completed the Health Care Providers' Pain and Impairment Relationship Scale (range 15 to 105). This questionnaire measures attitudes towards functioning in individuals with back pain. Fourth year physiotherapy students had more positive attitudes towards functioning in individuals with back pain than first year physiotherapy students [57.4 vs 66.6 (mean difference -9.2, 95% confidence interval -12.2 to -6.1, Pstudents had more positive attitudes towards functioning in individuals with back pain compared with first year non-healthcare students [69.2 vs 65.3 (mean difference -3.9, 95% confidence interval -7.2 to -0.5, P=0.03)]. Physiotherapy students had more positive attitudes than non-healthcare students in the first year [66.6 vs 69.2 (mean difference -2.6, 95% confidence interval -5.5 to 0.4, P=0.08)] and the fourth year [57.4 vs 65.3 (mean difference -7.9, 95% confidence interval -11.4 to -4.4, Pphysiotherapy education brings about positive student attitudes towards functioning in individuals with back pain. This may be partly attributable to receiving a university degree education, but would appear to be further enhanced by specifically receiving a physiotherapy degree. This may facilitate students to become more evidence-based practitioners following qualification. Copyright 2009 Chartered Society of Physiotherapy. Published by Elsevier Ltd. All rights reserved.

    Experiments were done under 252 Cf and 60 Co γ source to study the relation between heavy ion Single Event Upset (SEU) cross sections and γ accumulated doses. There was no obvious rule and little influence of γ accumulated doses on SEU cross sections when Static Random Access Memories were in power off mode and static power on mode. In active measuring mode, the SEU cross section increased as the accumulated doses increasing when same data were written in memory cells. If reverse data, such as '55' and 'AA', were written in memory cells during the experiment, the SEU cross sections decreased to the level when memories were not irradiated under 60 Co γ source, even more small. It implied that the influence of γ accumulated doses on SEU cross sections can be set off by this method

    Full Text Available Abstract Background There is general consent that empathy is crucial for the physician-patient relationship and thus an important issue in medical education. This comparative study was designed to examine the differences in empathy between first year and final year medical students in Jimma University, Ethiopia. Methods A comparative cross-sectional study among 131 first year and 106 final year medical students was conducted in Jimma University, Ethiopia on academic year 2010/11. The study subjects were selected using simple random sampling technique from the list of the students. Study participation was voluntary. The Balanced Emotional Empathy Scale (BEES was used for the detection of “heart-reading”, i.e. emotional empathy and the Reading the Mind in the Eyes test (RME-R test to evaluate “mind-reading”, i.e. cognitive empathy. We performed t-test to compare the mean difference in empathy and RME-R scores between the two groups of students. A linear regression was computed to identify potential factors influencing the BEES and RME-R. Results Out of the total 237 students, 207 (87.3% were males. The mean age of first year and final year students was 19.3 ± 1.1 and 24.0 ± 1.4 years respectively. First year students have scored 40.6 ± 23.8 while final year students scored 41.5 ± 20.8 mean in the BEES measuring emotional empathy score. However, this difference was not statistically significant (t = −0.30, df = 231, P-value >0.05. Final year students had significantly higher mean cognitive empathy score (17.8 ± 4.5 than first year students (14.4 ± 4.8 [β = 2.7, 95%CI (1.20, 4.13]. Males had scored lower cognitive [β = −2.5, 95%CI (−4.37, −0.66] and emotional empathy [β = −12.0, 95%CI (−21.66, −5.46]. Conclusions Low emotional (BEES and cognitive empathy sores were found in first year and final year students of Jimma University could have implications on the medical

    Dental assistants help the dentist in preparing material for filling teeth. Amalgam was the filling material mostly commonly used in Norway before 1980, and declined to about 5% of all fillings in 2005. Amalgam is usually an alloy of silver, copper, tin and mercury. Copper amalgam, giving particularly high exposure to mercury was used in Norway until 1994. Metallic mercury is neurotoxic. Few studies of the health of dental assistants exist, despite their exposure to mercury. There are questions about the existence of possible chronic neurological symptoms today within this working group, due to this exposure. The aim of this study was to compare the occurrence of neurological symptoms among dental assistants likely to be exposed to mercury from work with dental filling material, compared to similar health personnel with no such exposure. All dental assistants still at work and born before 1970 registered in the archives of a trade union in Hordaland county of Norway were invited to participate (response rate 68%, n = 41), as well as a similar number of randomly selected assistant nurses (response rate 87%, n = 64) in the same age group. The participants completed a self-administered, mailed questionnaire, with questions about demographic variables, life-style factors, musculoskeletal, neurological and psychosomatic symptoms (Euroquest). The dental assistants reported significant higher occurrence of neurological symptoms; psychosomatic symptoms, problems with memory, concentration, fatigue and sleep disturbance, but not for mood. This was found by analyses of variance, adjusting for age, education, alcohol consumption, smoking and personality traits. For each specific neurological symptom, adjusted logistic regression analyses were performed, showing that these symptoms were mainly from arms, hands, legs and balance organs. There is a possibility that the higher occurrence of neurological symptoms among the dental assistants may be related to their previous work

There are questions about the existence of possible chronic neurological symptoms today within this working group, due to this exposure. The aim of this study was to compare the occurrence of neurological symptoms among dental assistants likely to be exposed to mercury from work with dental filling material, compared to similar health personnel with no such exposure. Methods All dental assistants still at work and born before 1970 registered in the archives of a trade union in Hordaland county of Norway were invited to participate (response rate 68%, n = 41, as well as a similar number of randomly selected assistant nurses (response rate 87%, n = 64 in the same age group. The participants completed a self-administered, mailed questionnaire, with questions about demographic variables, life-style factors, musculoskeletal, neurological and psychosomatic symptoms (Euroquest. Results The dental assistants reported significant higher occurrence of neurological symptoms; psychosomatic symptoms, problems with memory, concentration, fatigue and sleep disturbance, but not for mood. This was found by analyses of variance, adjusting for age, education, alcohol consumption, smoking and personality traits. For each specific neurological symptom, adjusted logistic regression analyses were performed, showing that these symptoms were mainly from arms, hands, legs and balance organs. Conclusion There is a possibility that the higher occurrence of neurological symptoms

    Atopic dermatitis is a common skin disorder of unknown aetiology with peak incidence in early childhood. The disease is associated with peripheral T-cell accumulation in the skin. The thymus is a key organ of the cellular immune response early in life. We hypothesized that atopic dermatitis...... is associated with an unbalanced establishment of the peripheral T-lymphocyte system. This cross-sectional study was performed to compare thymus sizes in patients with atopic dermatitis and healthy controls. Thirty-seven children with current atopic dermatitis were enrolled and compared with 29 healthy controls...... of thymus is compatible with increased thymic activity and emission of T lymphocytes....

    To investigate the relationship between sarcopenia and diabetic nephropathy. 56 diabetic patients without complications, 50 diabetic patients with nephropathy, 53 healthy controls included in this present study. Demographic characteristics such as sex, age, anthropometric measurements such as weight, body mass index [BMI], hip circumference, waist circumference and upper arm circumference were measured. Sarcopenia diagnosis was based on European Working Group on Sarcopenia in Older People [EWGSOP] criteria which consist of hand grip strength, 6-meter walking test and muscle mass. The frequency of sarcopenia increased gradually from 15.1% in healthy control group to 21.4% in the diabetes group, and 34% in diabetic nephropathy group (X2 for trend, p = 0.029). The frequency of sarcopenia was similar in diabetes and diabetic nephropathy group. However, the frequency of sarcopenia was higher in diabetic nephropathy than healthy controls (OR = 2.89, CI [1.11-7.51] in logistic regression). In the present study, the prevalence of sarcopenia was higher in patients with diabetic nephropathy compared to healthy controls.

    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.

    The uncertainty evaluation with statistical method is performed by repetition of transport calculation with sampling the directly perturbed nuclear data. Hence, the reliable uncertainty result can be obtained by analyzing the results of the numerous transport calculations. One of the problems in the uncertainty analysis with the statistical approach is known as that the cross section sampling from the normal (Gaussian) distribution with relatively large standard deviation leads to the sampling error of the cross sections such as the sampling of the negative cross section. Some collection methods are noted; however, the methods can distort the distribution of the sampled cross sections. In this study, a sampling method of the nuclear data is proposed by using lognormal distribution. After that, the criticality calculations with sampled nuclear data are performed and the results are compared with that from the normal distribution which is conventionally used in the previous studies. In this study, the statistical sampling method of the cross section with the lognormal distribution was proposed to increase the sampling accuracy without negative sampling error. Also, a stochastic cross section sampling and writing program was developed. For the sensitivity and uncertainty analysis, the cross section sampling was pursued with the normal and lognormal distribution. The uncertainties, which are caused by covariance of (n,.) cross sections, were evaluated by solving GODIVA problem. The results show that the sampling method with lognormal distribution can efficiently solve the negative sampling problem referred in the previous studies. It is expected that this study will contribute to increase the accuracy of the sampling-based uncertainty analysis.

    Perceived better quality of care draws lower socio-economic classes of Indians to more expensive private setups, leading to poverty illness poverty cycle. Urgent measures need to be taken to improve perceived quality of public hospitals. The present study compares the difference in perceived quality of care among parents of children admitted at two government district hospitals. A cross-sectional, comparative, questionnaire based study was conducted between February 2011 and February 2012 at Government medical college hospitals of two district headquarters in South-India: one with private-public-partnership (PPP-model); another directly operated by government - Public Hospital-model (PH-model). A total of 461 inpatients from the PH model hospital and 580 from the PPP model hospital were eligible. Patients who left against advice (LAMA) (n=44 in PH and 19 in PPP) and expired (n=25 in PH and 59 in PPP) were excluded. Fourteen incomplete forms from PH and 10 from PPP model hospital were also excluded. Responders rated perception on a 1-5 scale in each domain: accessibility of health-facility, time spent waiting, manner and quality of physician, manner and quality of nurse, manner and quality of supporting staff, perception of equipment, explanation of treatment details and general comfort. The responders also rated overall satisfaction on a 1-10 scale. In the 1-5 scale, rating≥4 in each domain was considered good. Rating≥8 in 1-10 scale was considered satisfaction. Responders from PPP-model hospital were significantly more satisfied than those from PH-model {n=529 (91.2%) vs. n=148 (32.1%) p<0.001}. This was true even when controlled for age-group, sex, maternal education, family-type, days of hospital-stay and socioeconomic class {O.R.(CI) =23.58 (16.13-34.48); p<0.001} by binary logistic regression model. In the PPP-model hospital the time spent waiting for treatment {4.28(2.07-8.82), p<.001} and manner of support staff {3.64(1.02-12.99), p=0.04} significantly

    Neck pain is related to impaired postural balance among patients and is highly prevalent among workers with high postural demands, for example, cleaners. We therefore hypothesised, that cleaners with neck pain suffer from postural dysfunction. This cross-sectional study tested if cleaners with neck...... pain have an impaired postural balance compared with cleaners without neck pain. Postural balance of 194 cleaners with (n = 85) and without (N = 109) neck pain was studied using three different tests. Success or failure to maintain the standing position for 30 s in unilateral stance was recorded...... to cleaners without neck/low back pain (p balance, measured as CEA (p

    We explore the possibility to measure the elastic and inelastic ωN cross section in p+d→d+ω+p sp and p+A reactions. Our studies indicate that the elastic scattering cross sections can be determined for ω momenta above 1 GeV/c in p+d reactions by gating on high proton spectator momenta whereas the ωN absorption cross section down to low relative ω momenta is most effectively studied in p+A reactions at beam energies 2.0-2.7 GeV.

    Kato-Katz technique has been the mainstay test in Schistosoma mansoni diagnosis in endemic areas. However, recent studies have documented its poor sensitivity in evaluating Schistosoma mansoni infection especially in areas with lower rates of transmission. It's the primary diagnostic tool in monitoring impact of the Kenya national school based deworming program on infection transmission, but there is need to consider a more sensitive technique as the prevalence reduces. Therefore, this study explored the relationship between results of the stool-based Kato-Katz technique with urine-based point-of-care circulating cathodic antigen (POC-CCA) test in view to inform decision-making by the program in changing from Kato-Katz to POC-CCA test. We used two cross-sectional surveys conducted pre- and post- mass drug administration (MDA) using praziquantel in a representative random sample of children from 18 schools across 11 counties. A total of 1944 children were randomly sampled for the study. Stool and urine samples were tested for S. mansoni infection using Kato-Katz and POC-CCA methods, respectively. S. mansoni prevalence using each technique was calculated and 95% confidence intervals obtained using binomial regression model. Specificity (Sp) and sensitivity (Sn) were determined using 2 × 2 contingency tables and compared using the McNemar's chi-square test. A total of 1899 and 1878 children were surveyed at pre- and post-treatment respectively. S. mansoni infection prevalence was 26.5 and 21.4% during pre- and post-treatment respectively using POC-CCA test, and 4.9 and 1.5% for pre- and post-treatment respectively using Kato-Katz technique. Taking POC-CCA as the gold standard, Kato-Katz was found to have significantly lower sensitivity both at pre- and post-treatment, Sn = 12.5% and Sn = 5.2% respectively, McNemar test χ 2 m  = 782.0, p < 0.001. In overall, the results showed a slight/poor agreement between the two methods, kappa index (k

    Using the best current evidence to inform clinical decisions remains a challenge for clinicians. Given the scarcity of trustworthy clinical practice guidelines providing recommendations to answer clinicians' daily questions, clinical decision support systems (ie, assistance in question identification and answering) emerge as an attractive alternative. The trustworthiness of the recommendations achieved by such systems is unknown. To evaluate the trustworthiness of a question identification and answering system that delivers timely recommendations. Cross-sectional study. We compared the responses to 100 clinical questions related to inpatient management provided by two rapid response methods with 'Gold Standard' recommendations. One of the rapid methods was based on PubMed and the other on Epistemonikos database. We defined our 'Gold Standard' as trustworthy published evidence-based recommendations or, when unavailable, recommendations developed locally by a panel of six clinicians following the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Recommendations provided by the rapid strategies were classified as potentially misleading or reasonable. We also determined if the potentially misleading recommendations could have been avoided with the appropriate implementation of searching and evidence summary tools. We were able to answer all of the 100 questions with both rapid methods. Of the 200 recommendations obtained, 6.5% (95% CI 3% to 9.9%) were classified as potentially misleading and 93.5% (95% CI 90% to 96.9%) as reasonable. 6 of the 13 potentially misleading recommendations could have been avoided by the appropriate usage of the Epistemonikos matrix tool or by constructing summary of findings tables. No significant differences were observed between the evaluated rapid response methods. A question answering service based on the GRADE approach proved feasible to implement and provided appropriate guidance for most identified

    With the advent of cross sectional image of CT, ultrasound and magnetic resonance, the need for knowledge of cross sectional anatomy is stranger than ever. To meet this need, preparation of cross sectional anatomy specimen using cadaver is indispensable, not only because it tis the real cut surface anatomy but also because overt limitations of radiographic image in both contrast and special resolution. Authors prepared cross sectional anatomy specimen using a male cadaver, comprising photographs and slides of the 60 cross cut slices from the head to the pelvis. After photography, each slices was embedded using transparent resin allowing permanent preservation of specimen without altering its original architecture. Author's unique method of preparation is presented and 4 representative specimens are illustrated comparing cadaver's CT image, cross cut surface photography, and photography of resin embedded slice of the same cut surface.

    The need of efficient resource management and full-time accessibility to resources has increased with the development of industry, resulting in the increase of shift workers. Previous researches of past decades show that there are various health effects on shift workers. However, the definition and the form of shift work have varied from each research and occupational harmful factors except for shift work have not been excluded completely in previous researches. Therefore, in this research, we tried to find out the effect of shift work focusing on the hypertension. To complement previously mentioned weakness of other researches, we performed our research on participants to whom we could minimize other risk factors excluding shift work. This research examined 1,953 petrochemical plant male workers (shift work 1,075, day worker 878) who did medical checkup from 1st Jan. 2014 to 31th Dec. 2014 in a general hospital located in Ulsan, based on their medical records and questionnaires. With the questionnaire, we found out their basic information including age, social status, occupational history, and we took their physical measurements. Compared to day workers, shift workers' odds ratio of developing hypertension was 1.31 (95% CI 0.98-1.75). After adjusting confounding variables, adjusted odds ratio for entire subjects was 1.51 (95% CI 1.11-2.06). Also, for subjects who were in continuous service for over 20 years, odds ratio was 1.51 (95% CI 1.08-2.11). Shift workers had a higher chance of hypertension than day workers do. Particularly, the longer the workers work continuously, the risk of hypertension getting higher.

    Full Text Available The aim of this study is to assess the knowledge of the students in the Faculty of Dental Medicine of Iasi on the biocompatibility of the dental materials used in current practice. To this end, we elaborated our own questionnaire, including 10 questions to which 92 students from the last 2 years of study answered. The questionnaire cotains assertions on the potential toxic reactions of the most frequently used dental materials. The students answered correctly to the questions related to the biocompatibility of certain dental materials, such as glass-ionomer cement and calcium hydroxide, and they recognized that allergic reactions determined by acrylic resins may occur. We also noticed the lack of knowledge referring to the irreversible modifications produced by the tooth whitening substances on the enamel and dentin, as well as to the side effects produced by dental amalgam.

    Full Text Available For many ENT-clinicians, it is very difficult to diagnose the stage of infection and options available for treating retropharyngeal space abscesses (RPSAs with very limited literature available to focus on the treatment options in limited resource setup. The main cutting edge of the study aims to correlate post-surgical complications of RPSAs and also to know the age related incidence. MATERIALS AND METHODS A prospective and retrospective study was undertaken in the Department of ENT, Narayana Medical College & General Hospital, Nellore, Andhra Pradesh during the period of 2011-15. The incumbent laboratory parameters like throat swab culture was done for all the suspected patients along with Complete blood counts (CBC & X-ray neck. RESULTS A total sixty suspected paediatric patients were prospectively and retrospectively studied for the period of four years, out of which males 35 and females were 25 respectively. The mean age of the patient was 8.96±1.25 years (IQR 4-14 years median age was 10 years. Radiological examination and Computed tomography (CT scan was done for greater accuracy. Blocked airway is most common postsurgical intervention and it was found to be statistically significant (p<0.00 with respect to lower age group of the population. CONCLUSION The present study concludes that proper positioning and avoidance of unnecessary manipulation is essential for preventing the postoperative complications of RPSAs. The spread of infection to the spine can lead to replicate the osteomyelitis and vertebral erosion, which in turn results in subluxation and subsequent spinal cord injury, rupture of the abscess with inhalation of contents can lead to aspiration pneumonia (or rarely asphyxiation and spread of infection to mediastinum can lead to mediastinitis. More research could be intervened to prevent the infections at poor resource setup.

    Although most of maternal deaths are preventable, maternal mortality reduction programs have not been completely successful. As targeting individuals alone does not seem to be an effective strategy to reduce maternal mortality (Millennium Development Goal 5), the present study sought to reveal the role of many distant macrostructural factors affecting maternal mortality at the global level. After preparing a global dataset, 439 indicators were selected from nearly 1800 indicators based on their relevance and the application of proper inclusion and exclusion criteria. Then Pearson correlation coefficients were computed to assess the relationship between these indicators and maternal mortality. Only indicators with statistically significant correlation more than 0.2, and missing values less than 20% were maintained. Due to the high multicollinearity among the remaining indicators, after missing values analysis and imputation, factor analysis was performed with principal component analysis as the method of extraction. Ten factors were finally extracted and entered into a multiple regression analysis. The findings of this study not only consolidated the results of earlier studies about maternal mortality, but also added new evidence. Education (std. B = -0.442), private sector and trade (std. B = -0.316), and governance (std. B = -0.280) were found to be the most important macrostructural factors associated with maternal mortality. Employment and labor structure, economic policy and debt, agriculture and food production, private sector infrastructure investment, and health finance were also some other critical factors. These distal factors explained about 65% of the variability in maternal mortality between different countries. Decreasing maternal mortality requires dealing with various factors other than individual determinants including political will, reallocation of national resources (especially health resources) in the governmental sector, education

Patients and methods: A total of 197 outpatients (54.3% females diagnosed with schizophrenia spectrum disorders (schizophrenia, schizoaffective disorder, delusional disorder according to International Classification of Diseases – tenth edition participated in the study. The mean age of the patients was 40.10±11.49 years. All individuals completed the Internalized Stigma of Mental Illness (ISMI scale and a demographic questionnaire. The disorder severity was assessed by both a psychiatrist (the objective version of Clinical Global Impression – severity scale [objCGI-S] and the patients (the subjective version of Clinical Global Impression – severity scale [subjCGI-S]. Treatment with antipsychotics stabilized the patients. Results: The overall level of self-stigma measured by the total score of the ISMI was 63.32±13.59. The total score of the ISMI positively correlated with the severity of the disorder measured by the objCGI-S and subjCGI-S. In addition, self-stigma positively correlated with the treatment duration and the number of psychiatric hospitalizations. The backward stepwise regression was applied to identify the most significant factors connected to self-stigma. The regression analysis identified the following regressors as the most relevant to self-stigma: the number of

    Full Text Available Objective: This study aimed to identify certain risky behavior patterns (unsafe sex, tobacco and drug use, and binge drinking and the factors affecting these behaviors among first- and third-year students in a university. Method: The study included a total of 8407 students enrolled as first- (4392 and third- (4015 year students. A self-administered questionnaire was used for data collection. In data analysis, respecting sampling weights, models were formed by logistic regression method to determine factors that affect the risky behaviors. Results: 731 male–1114 female students from the first year and 560 male–1096 female students from the third year were interviewed. Male students were found to be engaged in risky behaviors more frequently than females. Logistic models of the study indicated that gender, place of residence, relationship with parents, and socialization with friends have profound effects on risky behaviors. Conclusion: After leaving home, young people develop their own lifestyles, and this study demonstrates that lifestyle is the main effective factor for risky behaviors in this group. Universities need to assume more responsibility to guide students’ lives and to provide the facilities and opportunities that encourage and facilitate their adoption of a healthy lifestyle.   Key Words: University students, risky behaviours Bir Üniversitede Öğrencilerin Riskli Davranışları: Kesitsel Bir Çalışma Amaç: Bu çalışmanın amacı, bir üniversitenin birinci ve üçüncü sınıf öğrencileri arasında bazı riskli davranış modellerini (güvensiz seks, tütün ve uyuşturucu kullanımı ve aşırı alkol ve bu davranışları etkileyen faktörleri saptamaktır.

    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

    Cross-sectional HIV incidence estimation based on a sensitive and less-sensitive test offers great advantages over the traditional cohort study. However, its use has been limited due to concerns about the false negative rate of the less-sensitive test, reflecting the phenomenon that some subjects may remain negative permanently on the less-sensitive test. Wang and Lagakos (2010) propose an augmented cross-sectional design which provides one way to estimate the size of the infected population ...

    Psoriasis, a chronic autoimmune skin disorder, is believed to contribute to cardiovascular diseases and metabolic syndrome. Psoriasis's association with the components of metabolic syndrome has been reported previously. However, large-scale cross-sectional studies about psoriasis and metabolic syndrome are rare in China. We assessed the prevalence of metabolic syndrome in Chinese psoriasis patients and controls. A total of 859 psoriasis patients and 1,718 controls were recruited in an age- and sex-matched cross-sectional study. Metabolic syndrome occurred in 14.3% of the psoriasis patients as opposed to 10.0% of the control participants (P = 0.001). Psoriasis patients had a higher prevalence of overweight/obesity, hyperglycemia and dyslipidemia when compared with controls. Meanwhile, psoriasis patients with metabolic syndrome were older, and had an older age of onset and a longer disease duration when compared with those without metabolic syndrome. The prevalence of metabolic syndrome is higher in the Chinese psoriatic population, which can favor cardiovascular events. The present study strengthens the value of treating psoriasis patients not only dealing with the skin lesions, and we suggest appropriate screening and relevant health education be carried out in the treatment of psoriasis patients. © 2017 The Authors.

    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 800 0 C.

    This study explored whether the risk assessment method, structured versus clinical judgment, influences pressure ulcer (PU) prevalence or prevention strategies. A cross section survey design was employed with use of a pre-designed data collection instrument. Following ethical approval and consent, data was gathered from two acute care settings, one in Norway (clinical judgment) and one in Ireland (structured risk assessment using the Maelor Score). Data were obtained from 180 patients, 59 in Norway and 121 in Ireland. Of the patients 48% were male and 49% were female, gender was not recorded for 3%. The most common age bracket was 70-99 years of age, 46% of the study population. PU prevalence was 54% in the Norwegian site with the majority of PUs (69%) being category 1, and 12% in the Irish site with the majority (50%) being category 2. Only 8% of patients in the Norwegian site were risk assessed on admission compared with 85% in the Irish site. No dynamic mattresses and four pressure redistribution cushions were in use in the Norwegian site, whereas, in the Irish site, 27 dynamic mattresses and 11 pressure redistribution cushions were used, the majority (44%) for high-risk individuals. Of those at risk of PU development, 15% in the Norwegian site and 56% in the Irish site had a documented repositioning care plan when in bed, and 0% in the Norwegian site and 13% in the Irish site for when seated on a chair. There were inconsistencies in approach to PU risk assessment and prevention across the two clinical settings. However, prevalence rates differed, mainly relating to category 1 PU damage. Even though formal risk assessment is well established in the Irish site, this is not necessarily followed up with appropriated PU prevention. Thus, the method of risk assessment does not seem to influence subsequent care planning, questioning the role of formal risk assessment; however, despite this, risk assessment does put a focus on an important clinical problem.

    Full Text Available Representational momentum (RM has been found to be magnified in experts (e.g., sport players with respect to both real and implied motion in expert-familiar domains. However, it remains unclear whether similar effects can be achieved in expert-unfamiliar domains, especially within the context of implied motion. To answer this question, we conducted two independent experiments using an implied motion paradigm and examined the expert effects of badminton training on RM in both adult and child players. In Experiment 1, we used a cross-sectional design and compared RM between adult professional badminton players and matched controls. The results revealed significantly enhanced RM for adult players, supporting the expert effect in expert-unfamiliar domains for implied motion. However, cross-sectional studies could not ascertain whether the observed expert effect was due to innate factors or expertise acquirement. Therefore, in Experiment 2, we used a longitudinal design and compared RM between two groups of child participants, naming child players who had enrolled professional badminton training program at a sports school and age-matched peer non-players who attended an ordinary primary school without sports training. Before training, there were no differences in RM among child players, their non-player peers, and adult non-players. However, after 4 years of badminton training, child players demonstrated significantly enhanced RM compared to themselves prior to training. The increased RM observed in both adult and child players suggests that badminton expertise modulates implied motion RM.

    In this work, we report theoretical and experimental cross sections for elastic scattering of electrons by chlorobenzene (ClB). The theoretical integral and differential cross sections (DCSs) were obtained with the Schwinger multichannel method implemented with pseudopotentials (SMCPP) and the independent atom method with screening corrected additivity rule (IAM-SCAR). The calculations with the SMCPP method were done in the static-exchange (SE) approximation, for energies above 12 eV, and in the static-exchange plus polarization approximation, for energies up to 12 eV. The calculations with the IAM-SCAR method covered energies up to 500 eV. The experimental differential cross sections were obtained in the high resolution electron energy loss spectrometer VG-SEELS 400, in Lisbon, for electron energies from 8.0 eV to 50 eV and angular range from 7{sup ∘} to 110{sup ∘}. From the present theoretical integral cross section (ICS) we discuss the low-energy shape-resonances present in chlorobenzene and compare our computed resonance spectra with available electron transmission spectroscopy data present in the literature. Since there is no other work in the literature reporting differential cross sections for this molecule, we compare our theoretical and experimental DCSs with experimental data available for the parent molecule benzene.

    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

    Students' self-regulated learning becomes essential with increased use of exploratory web-based activities such as virtual patients (VPs). The purpose was to investigate the interplay between students' self-regulated learning strategies and perceived benefit in VP learning activities. A cross-sectional study (n = 150) comparing students' study strategies and perceived benefit of a virtual patient learning activity in a clinical clerkship preparatory course. Teacher regulation varied among three settings and was classified from shared to strong. These settings were compared regarding their respective relations between regulation strategies and perceived benefit of the virtual patient activity. Self-regulation learning strategy was generally associated with perceived benefit of the VP activities (rho 0.27, p strategies can increase the value of flexible web-based learning resources to students.

    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.

    Helminths are one of the major health problems of working donkeys, often with heavy worm burden and contributing to their early demise and/or reduction in their work output. Cross-sectional and longitudinal studies were conducted to investigate the current infection prevalence and level of strongyles infection donkeys would acquire through different seasons in the mid-lowland agro-ecological zones of Ethiopia. For this purpose, faecal samples from 206 (cross-sectional study) and 102 (longitudinal study) randomly selected donkeys were directly collected from the rectum and analysed. For the longitudinal study, the 102 donkeys dewormed at the end of main rainy season, beginning of October, were monitored for the level of strongyle infection they would acquire during subsequent dry and short rainy seasons. The cross-sectional study of 206 donkey has revealed an overall infection prevalence of 89.3% (95% confidence interval (CI) = 84.4, 92.9). Donkeys in the lowland zone showed a significantly higher strongyle infection prevalence (P = 0.0126) and mean eggs per gramme of faces (EPG) (P = 0.001; 2775 EPG) compared to donkeys in the midland zone (980.8 EPG). Age, sex and body condition did not have any significant effect on either the infection prevalence or level of infection (P > 0.05). The longitudinal study has shown a significantly lower strongyle infection prevalence (P = 0.003) and level of infection donkeys acquired (P = 0.001) in the subsequent dry and short rainy seasons compared to the main rainy season following October deworming. However, these values were not significantly different between the two agro-ecological zones (P > 0.05). This study clearly showed that parasitic infections are primarily acquired during the main rainy season when pasture/herbage coverage is relatively better, and the environment is conducive for parasites survival and development. On the other hand, the finding of majority of donkeys shedding low or no eggs during the

    2017-05-01

    In this article, the electromagnetic wave scattering from plasma columns with inhomogeneous electron density distribution is studied by the Green's function volume integral equation method. Due to the ready production of such plasmas in the laboratories and their practical application in various technological fields, this study tries to find the effects of plasma parameters such as the electron density, radius, and pressure on the scattering cross-section of a plasma column. Moreover, the incident wave frequency influence of the scattering pattern is demonstrated. Furthermore, the scattering cross-section of a plasma column with an inhomogeneous collision frequency profile is calculated and the effect of this inhomogeneity is discussed first in this article. These results are especially used to determine the appropriate conditions for radar cross-section reduction purposes. It is shown that the radar cross-section of a plasma column reduces more for a larger collision frequency, for a relatively lower plasma frequency, and also for a smaller radius. Furthermore, it is found that the effect of the electron density on the scattering cross-section is more obvious in comparison with the effect of other plasma parameters. Also, the plasma column with homogenous collision frequency can be used as a better shielding in contrast to its inhomogeneous counterpart.

    Full Text Available Ageing is associated with changes at the molecular and cellular level that can alter cardiovascular function and ultimately lead to disease. The baboon is an ideal model for studying ageing due to the similarities in genetic, anatomical, physiological and biochemical characteristics with humans. The aim of this cross-sectional study was to investigate the changes in cardiovascular profile of baboons over the course of their lifespan.Data were collected from 109 healthy baboons (Papio hamadryas at the Australian National Baboon Colony. A linear regression model, adjusting for sex, was used to analyse the association between age and markers of ageing with P 12 years had significantly shorter telomeres when compared to younger (<3 years baboons (P = 0.001.This study is the first to demonstrate that cardiovascular function alters with age in the baboon. This research identifies similarities within cardiovascular parameters between humans and baboon even though the length of life differs between the two species.

  6. Cross section sensitivity study for fusion blankets incorporating lead neutron multiplier

    1983-01-01

    In the recent European INTOR design, lead has been considered for incorporation in the blanket as either an explicit or implicit neutron multiplier. The blanket employs either Li 2 SiO 3 or Li 17 Pb 83 as tritium breeding material. Nucleonic analysis was performed for this blanket using the DLC37 and DLC41 cross section libraries. The reaction rates were estimated using the reaction cross sections provided with both libraries. In addition to that, they were estimated using the MACKLIB-IV response library. The calculated tritium breeding ratio was found to be 5% less and 15% more in the calculations with DLC41 and DLC41 plus MACKLIB-IV libraries, respectively, than in the calculation with the DLC37 library. The Fe, Pb, and Li cross sections given by the ENDF/B-IV and V were reviewed. A sensitivity study of these cross section uncertainties shows that the tritium breeding ratio is relatively insensitive to the above mentioned partial cross sections. The calculated tritium breeding ratio can be known within +-2%. (Auth.)

    Background: Increases in cancer survival have made understanding the basis of cancer-related cognitive impairment (CRCI) more important. CRCI neuroimaging studies have traditionally used dedicated research brain MRIs in breast cancer survivors with small sample sizes; little is known about other non-CNS cancers. However, there is a wealth of unused data from clinically-indicated MRIs that could be used to study CRCI. Objective: Evaluate brain cortical structural differences in those with non-CNS cancers using clinically-indicated MRIs. Design: Cross-sectional Patients: Adult non-CNS cancer and non-cancer control (C) patients who underwent clinically-indicated MRIs. Methods: Brain cortical surface area and thickness were measured using 3D T1-weighted images. An age-adjusted linear regression model was used and the Benjamini and Hochberg false discovery rate (FDR) corrected for multiple comparisons. Group comparisons were: cancer cases with chemotherapy (Ch+), cancer cases without chemotherapy (Ch-) and subgroup of lung cancer cases with and without chemotherapy vs C. Results: Sixty-four subjects were analyzed: 22 Ch+, 23 Ch- and 19 C patients. Subgroup analysis of 16 LCa was also performed. Statistically significant decreases in either cortical surface area or thickness were found in multiple ROIs primarily within the frontal and temporal lobes for all comparisons. Limitations: Several limitations were apparent including a small sample size that precluded adjustment for other covariates. Conclusions: Our preliminary results suggest that various types of non-CNS cancers, both with and without chemotherapy, may result in brain structural abnormalities. Also, there is a wealth of untapped clinical MRIs that could be used for future CRCI studies.

    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 big Quinta uranium target at Joint Institute for Nuclear Research (JINR) in Dubna, Russia. The deuteron beams with energies ranging from 1 GeV up to 8 GeV were produced by JINR Nuclotron. Residual nuclides were identified by the gamma spectrometry. Lack of such experimental cross-section values prevents the usage of copper foils from beam integral monitoring.

    According to World Health Organization, for every committed suicide there were 20 suicide attempts at least. In the last decade, despite the increasing awareness on suicide attempts among adolescents in China, there has been no comprehensive system reporting vital statistics. Consequently, the prevalence of suicide attempts reported in some studies ranged variedly. Therefore, the purpose of this study was to provide the first meta-analysis of cross-sectional studies of suicide attempts to fill this gap. Two reviewers independently screened potentially relevant cross-sectional studies of suicide attempts through PubMed-Medline, Embase, Wanfang Data, Chongqing VIP and Chinese National Knowledge Infrastructure databases using the core terms 'suicid*'/'suicide attempt*'/'attempted suicide' and 'adolescen*'/'youth'/'child*'/'student*' and 'China'/'Chinese' in the article titles, abstracts and keywords. Chi-square based Q test and I(2) statistic assessed the heterogeneity. Forest plot was used to display results graphically. Potential publication bias was assessed by the funnel plot, Begg's and Egger's test. In total, 43 studies with 200,124 participants met the eligibility criteria. The pooled prevalence of suicide attempts among Chinese adolescents was 2.94% (95% CI: 2.53%-3.41%). Substantial heterogeneity in prevalence estimates was revealed. Subgroup analyses showed that the prevalence for males was 2.50% (95% CI: 2.08%-3.01%), and for females was 3.17% (95% CI: 2.56%-3.91%). In sum, abstracting across the literatures, the prevalence of suicide attempts among Chinese adolescents was moderate compared with other countries around the world. Necessary measures should be set out prevent them in the future. Copyright © 2015 Elsevier Inc. All rights reserved.

    Epoxy adhesives contain organic solvents and are widely used in industry. The hazardous effects of epoxy adhesives remain unclear. The objective of this study was to investigate the risk of hearing loss among workers exposed to epoxy adhesives and noise. Cross-sectional study. For this cross-sectional study, we recruited 182 stone workers who were exposed to both epoxy adhesives and noise, 89 stone workers who were exposed to noise only, and 43 workers from the administrative staff who had not been exposed to adhesives or noise. We obtained demographic data, occupational history and medical history through face-to-face interviews and arranged physical examinations and pure-tone audiometric tests. We also conducted walk-through surveys in the stone industry. A total of 40 representative noise assessments were conducted in 15 workplaces. Air sampling was conducted at 40 workplaces, and volatile organic compounds were analysed using the Environmental Protection Agency (EPA) TO-15 method. The mean sound pressure level was 87.7 dBA (SD 9.9). The prevalence of noise-induced hearing loss was considerably increased in the stone workers exposed to epoxy adhesives (42%) compared with the stone workers who were not exposed to epoxy adhesives (21%) and the administrative staff group (9.3%). A multivariate logistic regression analysis revealed that exposure to epoxy adhesives significantly increased the risk of hearing loss between 2 and 6 kHz after adjusting for age. Significant interactions between epoxy adhesives and noise and hearing impairment were observed at 3, 4 and 6 kHz. Epoxy adhesives exacerbate hearing impairment in noisy environments, with the main impacts occurring in the middle and high frequencies. Published by the BMJ Publishing Group Limited.

    Study Objectives: To evaluate the sleep pattern and the motor activity during sleep in a cohort of patients affected by Huntington disease (HD). Design: Cross-sectional cohort study. Setting: Sleep laboratory. Patients: Thirty HD patients, 16 women and 14 men (mean age 57.3 ± 12.2 y); 30 matched healthy controls (mean age 56.5 ± 11.8 y). Interventions: Subjective sleep evaluation: Epworth Sleepiness Scale (ESS); Berlin's Questionnaire, interview for restless legs syndrome (RLS), questionnaire for REM sleep behavior disorder (RBD). Clinical evaluation: disease duration, clinical severity (unified Huntington disease motor rating scale [UHDMRS]), genetic tests. Laboratory-based full-night attended video-polysomnography (V-PSG). Measurements and Results: The duration of the disease was 9.4 ± 4.4 y, UHMDRS score was 55.5 ± 23.4, CAG repeats were 44.3 ± 4.1. Body mass index was 21.9 ± 4.0 kg/m2. No patients or caregivers reported poor sleep quality. Two patients reported symptoms of RLS. Eight patients had an ESS score ≥ 9. Eight patients had high risk of obstructive sleep apnea. At the RBD questionnaire, two patients had a pathological score. HD patients, compared to controls, showed shorter sleep, reduced sleep efficiency index, and increased arousals and awakenings. Four patients presented with sleep disordered breathing (SDB). Periodic limb movements (PLMs) during wake and sleep were observed in all patients. No episode of RBD was observed in the V-PSG recordings, and no patients showed rapid eye movement (REM) sleep without atonia. The disease duration correlated with ESS score (P Marca G, Solito M, Calandra-Buonaura G, Provini F, Bentivoglio AR, Cortelli P.

    Full Text Available "nBackground and Aim: By definition, pontic is an artificial replacement of missing tooth (teeth which is essentially used to establish function and esthetics. In order to this fact that, pontic(s is not completely the same as tooth (teeth to be replaced, it may not be concern as a simple type of restoration to achieve the best result, it must be design from the esthetically and hygienically point of view as well as comfort, demand and tissue health of patient. The main purpose of this study is to investigate the pontic designs and their relationship to edentulous partial aras. "nMaterials and Methods: 73 pontics in 57 patients have been included in this cross-sectional study. These patients were under treatment in the department of prosthodontics. A primary cast was achieved from each patient and then the cross-sectional contour of edentulous ridge was depicted. For each patient the type of pontic design was derived from textbook standards and then compared with the design of actual verified Prosthesis at delivery. The shape of tissue surface of each denture was determined by a low viscous impression material. The result of each comparison was recorded in a chart data set. "nResults: The most common pontic design was Modified ridge lap with frequency of 93.2%. 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.

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

    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

    2016-04-01

    A major problem occurring in cross-sectional studies is sampling bias. Length of hospital stay (LOS) differs strongly between patients and causes a length bias as patients with longer LOS are more likely to be included and are therefore overrepresented in this type of study. To adjust for the length bias higher weights are allocated to patients with shorter LOS. We determined the effect of length-bias adjustment in two independent populations. Length-bias correction is applied to the data of the nutritionDay project, a one-day multinational cross-sectional audit capturing data on disease and nutrition of patients admitted to hospital wards with right-censoring after 30 days follow-up. We applied the weighting method for estimating the distribution function of patient baseline variables based on the method of non-parametric maximum likelihood. Results are validated using data from all patients admitted to the General Hospital of Vienna between 2005 and 2009, where the distribution of LOS can be assumed to be known. Additionally, a simplified calculation scheme for estimating the adjusted distribution function of LOS is demonstrated on a small patient example. The crude median (lower quartile; upper quartile) LOS in the cross-sectional sample was 14 (8; 24) and decreased to 7 (4; 12) when adjusted. Hence, adjustment for length bias in cross-sectional studies is essential to get appropriate estimates. Copyright © 2015 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

  8. Criticality studies of fast assemblies with the new 27-group cross-section set

    International Nuclear Information System (INIS)

    Garg, S.B.; Shukla, V.K.

    1976-01-01

    A test of 27-group cross-section set (Garg-set) recently derived from ENDF/B library has been carried out in the criticality studies of the Pu 239 , U 235 and U 233 based metal, oxide and carbide fuelled fast critical assemblies. A total of twenty fast critical assemblies of different sizes and varying neutron spectra have been selected for analysis. Based on these analyses it has been observed that the Garg-set predicts well the criticality of uranium and plutonium based hard-spectra assemblies. In the soft-spectra systems it underpredicts criticality because of the following reasons: (a) It makes use of the higher capture cross-sections of structural and coolant elements given in ENDF/B - Version IV library. (b) It does not account for the resonance self-shielding effects of cross-sections. It has also been observed that the Garg-set gives better results than the MABBN-set for dense and dilute plutonium-based and the hard uranium-based assemblies. This superior trend of the Garg-set is slightly lost in the uranium-based dilute systems because of large differences in the capture cross-sections of structural elements of these two sets. (author)

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

    El Maddarsi, Mohamed.

    1978-01-01

    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 -15 cm 2 , corresponding to 1.6% of the scattering process [fr

    This is a case-control study. The present study aimed to compare the cross-sectional areas of the psoas major and multifidus muscles between elderly patients with adult spinal deformity (ASD) and age-matched and body weight-matched controls, and to evaluate the associations between the cross-sectional areas of these muscles and the severity of spinal deformity. The study included 49 female kyphosis patients with mild scoliosis (Cobb angle muscles were calculated using preoperative L4/L5 axial computed tomography images. In group D, the following spinopelvic parameters were assessed: sagittal vertical axis, pelvic tilt, pelvic incidence, lumbar lordosis, and thoracic kyphosis. The relationships between the muscle cross-sectional areas and spinopelvic parameters were evaluated. The cross-sectional area of the multifidus muscle was lower in group D than in group C. However, the cross-sectional area of the psoas major muscle was not different between the 2 groups. In multiple regression analysis, the cross-sectional area of the multifidus muscle was significantly associated with all spinopelvic parameters. The cross-sectional area of the multifidus muscle might be lower in elderly patients with ASD than in controls. In the elderly population, the severity of sagittal spinal deformity might be correlated with the cross-sectional area of the multifidus muscle. Therefore, muscle imbalances between the flexors and extensors of the spine could participate in the pathology of ASD.

    Highlights: → Excitation function measurement of deuteron induced reactions on rhodium up to 40 MeV. → Model code calculations with EMPIRE, ALICE and TALYS. → Integral production yield calculation. → Thin layer activation (TLA) with the produced isotopes. - Abstract: In the frame of a systematic study of the activation cross-sections of deuteron induced nuclear reactions, excitation functions of the 103 Rh(d,x) 100,101,103 Pd, 100g,101m,101g,102m,102g Rh and 103g Ru reactions were determined up to 40 MeV. Cross-sections were measured with the activation method using a stacked foil irradiation technique. Excitation functions of the contributing reactions were calculated using the ALICE-IPPE, EMPIRE-II and TALYS codes. From the measured cross-section data integral production yields were calculated and compared with experimental integral yield data reported in the literature. From the measured cross-sections and previous data, activation curves were deduced to support thin layer activation (TLA) on rhodium and Rh containing alloys.

    Background: Sexual dysfunction (SD) is a known adverse effect of psychotropic medications. Even though sexual difficulties are common among women; very few studies have been carried out in India. Objective: To study the prevalence and nature of SD among females receiving psychotropic medications and to compare the SD among female patients receiving antipsychotics and antidepressants. Materials and Methods: Female investigator conducted a hospital-based cross-sectional study on female patients visiting the psychiatry outpatient department. Patients meeting inclusion criteria were assessed for SD disorder as per Diagnostic and Statistical Manual of Mental Disorders 4th Edition Text Revision. SD severity was measured using Female Sexual Function Index (FSFI) scale. Results: The prevalence of SD in this study was 68.32%. There was more than one SD in 48 (47.52%). FSFI score was significantly low in patients with SD as compared to patients not having SD (P = 0.001). SD was more common in patients who were on combination of antidepressants and benzodiazepines than antidepressant alone or antipsychotic alone. Conclusion: SD was prevalent in more than 50% of female patients on psychotropic drugs. Number of patients on individual psychotropic drugs was so small that a definite conclusion could not be drawn. Study emphasizes the need to carry out similar study on larger number of patients to get better insight into this problem. PMID:27833229

    The aim of this study is to explore and compare through polysomnography respiratory sleep parameters between children with idiopathic epilepsy and healthy children. Our cross-sectional study included 40 children with idiopathic epilepsy and 27 healthy children, who underwent overnight polysomnography. Data about sleep respiratory parameters were obtained and statistically analyzed. The level of statistical significance was set at 0.05. The prevalence of Obstructive Sleep Apnea Syndrome was significantly higher in the epilepsy group (35% vs 7.4%, pepilepsy group was 10.6 (95% Confidence Intervals: 3.08-37.08) in comparison to the control group. The mean value of the obstructive apnea-hypopnea index was significantly higher in children with epilepsy compared to healthy children (2.46±1.22 vs 1.21±0.83, p=0.027). The mean values of central apnea index and desaturation index were comparable between these two groups. Longest apnea duration was significantly higher in the group of poor seizure control. All other sleep respiratory variables did not differ significantly between children with poor and good seizure control and between children with generalized and focal epilepsy. Children with epilepsy seem to present more prominent sleep breathing instability in comparison to healthy children, which mainly includes a predisposition to obstructive respiratory events. More studies are needed to investigate the relationship between sleep apneas and seizure control. Copyright © 2016 Elsevier B.V. All rights reserved.

    Bicycle riding has become an increasingly popular mode of transportation and exercise, especially among women, and previous studies have demonstrated a relationship between cycling and sexual dysfunction, albeit using non-validated questionnaires. We aimed to explore the relationship between cycling and sexual and urinary dysfunction. Cyclists were recruited to complete a survey through Facebook advertisements and outreach to sporting clubs across 5 English-speaking countries. Swimmers and runners were recruited as a comparison group. Participants were queried using validated questionnaires, including the Female Sexual Function Index, the American Urological Association Symptom Index, and non-validated questions about history of urinary tract infections (UTIs), genital numbness, and genital saddle sores (all self-reported). 3,118 (53.3%) Women completed the survey, comprising 1,053 (34%) non-cyclists, 1,656 (53%) low-intensity cyclists, and 409 (13%) high-intensity cyclists. After adjusting for age, body mass index, hypertension, diabetes, ischemic heart disease, tobacco use, race, marital status, urinary symptoms, and sexual activity, high-intensity cyclists had lower odds of self-reported sexual dysfunction compared to non-cyclists (adjusted odds ratio [aOR] 0.7, P = .02). There were no statistically significant differences in urinary symptoms across groups. Compared to non-cyclists, both low- and high-intensity cyclists had higher odds of reporting a previous UTI (aOR 1.4, P < .001, and aOR 1.4, P = .009, respectively), genital numbness (odds ratio [OR] 6.5, P < .001, and OR 9.1, P < .001, respectively), and saddle sores (OR 6.3, P < .001, and OR 22.7, P < .001, respectively). Women cyclists were more likely to report other genitourinary conditions, including UTIs, genital numbness, and saddle sores. This is the largest study comparing cyclists to other athletes with respect to sexual and urinary function. The study is limited by its cross-sectional design

    Background. Diabetes has been associated with psoriasis, but little is known about the association between psoriatic arthritis and diabetes. Methods. Patients diagnosed with psoriatic arthritis by a rheumatologist were compared to age- and sex-matched patients without psoriatic arthritis regarding the prevalence of diabetes in a population-based cross-sectional study using logistic multivariate models. The study was performed utilizing the medical database of Clalit, the largest healthcare provider organization in Israel. Results. The study included 549 patients with psoriatic arthritis ≥21 years and 1,098 patients without psoriatic arthritis. The prevalence of diabetes in patients with psoriatic arthritis was increased as compared to the prevalence in patients without psoriatic arthritis (15.3% versus 10.7%, P value = 0.008). The difference was prominent among females (18.7% versus 10.3%, P < 0.001) but not among males (11.2% in patients with and without psoriatic arthritis, P = 1.000). In a multivariate analysis, psoriatic arthritis was associated with diabetes among females (OR = 1.60, 95% CI: 1.02–2.52, P = 0.040) but not among males (OR = 0.71, 95% CI: 0.42–1.22, P = 0.213). Conclusion. Our study suggests a possible association between psoriatic arthritis and diabetes in women. Women with psoriatic arthritis might be candidates for diabetes screening. PMID:23843781

    Increasing evidence suggests that serum CA 19-9 is associated with abnormal glucose metabolism. However, data on the association between CA 19-9 and metabolic syndrome is limited. The aim of the present study was to investigate the association between serum CA 19-9 and metabolic syndrome. A cross-sectional study was conducted on 3641 participants aged ≥40 years from the Songnan Community, Baoshan District in Shanghai, China. Logistic regression analysis was used to evaluate the association between serum CA 19-9 and metabolic syndrome. Multivariate logistic regression analysis showed that compared with participants in the first tertile of serum CA 19-9, those in the second and third tertiles had increased odds ratios (OR) for prevalent metabolic syndrome (multivariate adjusted OR 1.46 [95% confidence interval {CI} 1.11-1.92] and 1.51 [95% CI 1.14-1.98]; P trend  = 0.005). In addition, participants with elevated serum CA 19-9 (≥37 U/mL) had an increased risk of prevalent metabolic syndrome compared with those with serum CA 19-9 metabolic syndrome. In order to confirm this association and identify potential mechanisms, prospective cohort and mechanic studies should be performed. © 2017 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

  19. Neck pain and postural balance among workers with high postural demands - a cross-sectional study

    Science.gov (United States)

    2011-01-01

    Background Neck pain is related to impaired postural balance among patients and is highly prevalent among workers with high postural demands, for example, cleaners. We therefore hypothesised, that cleaners with neck pain suffer from postural dysfunction. This cross-sectional study tested if cleaners with neck pain have an impaired postural balance compared with cleaners without neck pain. Methods Postural balance of 194 cleaners with (n = 85) and without (N = 109) neck pain was studied using three different tests. Success or failure to maintain the standing position for 30 s in unilateral stance was recorded. Participants were asked to stand on a force platform for 30 s in the Romberg position with eyes open and closed. The centre of pressure of the sway was calculated, and separated into a slow (rambling) and fast (trembling) component. Subsequently, the 95% confidence ellipse area (CEA) was calculated. Furthermore a perturbation test was performed. Results More cleaners with neck pain (81%) failed the unilateral stance compared with cleaners without neck pain (61%) (p neck pain in comparison with cleaners without neck pain in the Romberg position with eyes closed, but not with eyes open. Conclusions Postural balance is impaired among cleaners with neck pain and the current study suggests a particular role of the slow component of postural sway. Furthermore, the unilateral stance test is a simple test to illustrate functional impairment among cleaners with concurrent neck and low back pain. Trial registration ISRCTN96241850 PMID:21806796

    Worldwide, at least 200 million women and girls have undergone female genital mutilation (FGM). The medical and sexual consequences have been documented, but the psychological impact has not been studied to the same extent. The aim of this study was to explore the relationship between FGM and psychiatric problems among adolescent girls. A total of 204 girls, aged 14-19 years, were included in a cross-sectional study conducted at Suez Canal University Hospitals. All participants completed an Arabic-validated, structured questionnaire covering nine symptom scales. Sociodemographic data were also collected. Main outcome measures were the prevalence of psychiatric problems among adolescent girls who had undergone FGM. Overall, 66.2% of girls had undergone FGM. The percentage in rural areas was 91.8%, compared with 43.0% in urban areas. There were no significant differences between the FGM and non-FGM groups as regards religion, educational and socioeconomic levels. FGM girls had a significantly higher level of psychological problems with regard to somatisation, depression, anxiety, phobic anxiety and hostility compared with non-FGM girls (p < .0001). FGM is a traumatic experience that may leave a lasting psychological mark and a negative impact on the psychological status of affected girls.

    Nutrition clubs (NC) operate in community settings and provide members with nutrition education and meal replacements for weight management. NC are owned and operated by distributors of Herbalife products. There are over 6200 NC in the US, but there has been no independent assessment of the association of these NC with biomarkers of health. We conducted a cross-sectional pilot study to compare the health status of 100 NC members to 100 community-matched controls (CC) in the greater Boston area. Each CC was matched to a NC member for community of residence (zip code), age category, gender, BMI category, race/ethnicity, education level (category), and readiness to make health changes. Measures obtained included cardio-metabolic risk factors, body composition, markers of nutritional status, reported health status, dietary intake, physical activity, sleep and depression. Participants were predominantly female (64%) and Hispanic (73%). NC members had significantly lower fasting insulin (P Herbalife NC membership for themselves and their families. A higher percentage of NC members (86%) compared to CC (32%) reported being in much better or somewhat better health compared to a year ago (P Herbalife NC membership was positively associated with perceived health and measured cardiometabolic benefits. However, causality cannot be inferred from these findings.

    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

    As early as in 1898, it was noted that there was a need to find "a plausible explanation of the long recognized affinities of migraine and epilepsy". However, results of recent studies are clearly conflicting on this matter. In this cross-sectional study, we aimed to define the prevalence and characteristics of both seizure-related and interictal headaches in patients with epilepsy (5-75years) seeking help in the tertiary epilepsy clinic SEIN in Zwolle. Using a questionnaire, subjects were surveyed on the existence of headaches including characteristics, duration, severity, and accompanying symptoms. Furthermore, details on epilepsy were retrieved from medical records (e.g., syndrome, seizure frequency, and use of drugs). Diagnoses of migraine, tension-type headache, or unclassifiable headache were made based on criteria of the International Classification of Headache Disorders. Between March and December 2013, 29 children and 226 adults were evaluated, 73% of whom indicated having current headaches, which is significantly more often when compared with the general population (pheadache, while 29% had solely seizure-related headaches and 22% had both. Migraine occurs significantly more often in people with epilepsy in comparison with the general population (pheadaches conforms to results in the general population. These results show that current headaches are a significantly more frequent problem amongst people with epilepsy than in people without epilepsy. When comparing migraine prevalence, this is significantly higher in the population of patients with epilepsy. Copyright © 2014 Elsevier Inc. All rights reserved.

    The aim of this study was to evaluate tear osmolarity and tear film function and ocular surface changes in patients with metabolic syndrome. 108 eyes of 64 patients with metabolic syndrome (group 1) and 110 eyes of 55 healthy individuals (group 2) were included in this cross-sectional study. All participants were evaluated using the Ocular Surface Disease Index (OSDI) questionnaire, Schirmer I test, tear film break-up time (TBUT), and tear osmolarity. Main outcome measures were Ocular Surface Disease Index (OSDI) questionnaire, Schirmer I test, tear film break-up time (TBUT), and tear osmolarity values. Tear osmolarity values and OSDI scores were significantly higher in group 1 (314.4 ± 19.1 mOsm and 38.9 ± 1.1, respectively) compared with group 2 (295 ± 14.3 mOsm and 18.69 ± 17.2, respectively) (p = 0.01 for both). The Schirmer test values and TBUT in group 1 (10 ± 3.7 mm and 14.8 ± 3.6 sec, respectively) were significantly lower compared with group 2 (16.8 ± 2.6 mm and 18.1 ± 0.5 sec, respectively) (p syndrome can influence tear osmolarity and tear film function. Patients with metabolic syndrome showed tear hyperosmolarity and tear film dysfunction.

    Full Text Available In a resource-limited and high-burden disease setting, satisfied health professional is an asset in terms of maximized productivity, efficiency and quality health care. Job Satisfaction Index is a validated measure to identify the components that influence those issues. A multi-faceted structured questionnaire study was conducted upon a cross-section of medical educators (n=160 serving two tertiary care teaching institutions under different management set-up. Multiple demographic features were independent variables whereas three (3 critical areas of satisfaction index (SI were outcome variables. All participants were interviewed using 15 item Likert response-based, modified job satisfaction scale. It was observed that total SI scores among doctors representing the private group remained marginally higher (P<0.05 while compared to the other group. The comparative analysis of SI scores in critical areas like availability of academic supports and job security remained higher among the private doctors than that of the government ones though not significant. However the private doctors remained marginally satisfied in terms of working environment. The study outcome necessitates appropriate intervention measures at the organizational levels.

    This purpose of the study was to increase the visibility on radar for unprotected pedestrians with the aid of conducting fabric. The experiment comprised measurements of four types of fabric to determine the radio frequency properties, such as radar cross section (RCS) for the vehicle radar frequency 77 GHz and transmission (shielding) in the frequency range 3-18 GHz. Two different thicknesses of polypyrrole (PPy) nonvowen fabric were tested and one thickness for 30 % and 40 % stainless steel fabrics respectively. A jacket with the thinner nonvowen material and one with 40 % steel were tested and compared to an unmodified jacket in the RCS measurement. The measurement showed an increase in RCS of 4 dB for the jacket with the 40 % steel lining compared to the unmodified jacket. The transmission measurement was aimed at determining the fabric with the highest transmission of an incoming radio wave. The 30 % steel fabric and the two thicknesses of the nonvowen fabrics were tested. One practical application is for example the use of radar reflective material in search and rescue (SAR) clothes. The study showed that the 30 % steel fabric was the best candidate for further RCS measurements.

This study investigated the association of OPRM1 polymorphisms with subjective sleep quality among opioid-naive individuals. This cross-sectional observational study involved 161 opioid-naive males (mean age = 27.74 years; range: 18−63 years. Subjective sleep quality was assessed with the translated and validated Malay version of the Pittsburgh Sleep Quality Index (PSQI. DNA was extracted from whole blood and subjected to polymerase chain reaction (PCR-genotyping for two OPRM1 polymorphisms (118A>G and IVS2+691G>C. Subjects with combined 118A and IVS2+691G alleles (AC haplotype had significantly lower PSQI scores [mean (SD = 4.29 (1.76] compared to those without the haplotype [4.99 (2.50] (p = 0.004. On the other hand, subjects with combined heterozygous genotype (GC/AG diplotype had significantly higher PSQI scores compared to those without the diplotype [6.04 (2.48 vs 4.54 (2.22, p = 0.004]. In opioid-naive individuals, AC haplotype and GC/AG diplotype for the 118A>G and IVS2+691G>C polymorphisms of OPRM1 are associated with better and poorer sleep quality, respectively.

    In this study, we described the profile of advanced nursing practice in Spain. A cross-sectional study design was used to explore the extent and patterns of advanced nursing practice activity within the domains of expert care planning, integrated care, interprofessional collaboration, education, research, evidence-based practice, and professional leadership. Data were collected in 2015/2016. Purposive sampling yielded a sample of 165 specialist and expert nurses employed by a dual tertiary and community hospital in an urban setting. The study included specialist and expert nurses who had a higher practice profile than registered general nurses. The performance of activities according to age, current position, years of experience, nursing grade, and education was compared. Practice domains were more strongly influenced by the predictors of nursing position and professional career ladder. Age and experience predictors were found to be weak predictors of advanced practice domains. This study offers essential information of the nursing workforce, and clarifies both the advanced nursing practice profile and nomenclature in the context of study. © 2017 John Wiley & Sons Australia, Ltd.

    Intense migrations from tuberculosis endemic areas to Gulf countries create special risks for people in the region. The purpose of this study was to provide data that could justify implementing universal, regular TB screening in UAE. This prospective, cross-sectional study used interferon-γ release assay (IGRA) to screen for TB among Emirati citizens between August-2016 and May-2017; expatriates were not included in this study. Participants were recruited from Emiratis attending Tawam Hospital Polyclinics for problems unrelated to TB risk assessment. IGRA was requested for all enrolled participants. A risk-assessment questionnaire was completed by all participants. In addition, a retrospective review of IGRA results (January-2011 to April-2016) was conducted to compare prevalence of positive IGRA in the 'prospective sample' with that in 'patients screened in the past'. Four hundred fifty-five participants (69% females) were enrolled in this study. Participants' age (mean±SD) was 42±16y. The majority of participants had traveled to or had helpers from TB-endemic areas. Two hundred forty (53%) participants had IGRA test. Forty-five (18.8%) participants had positive IGRA, similar to the retrospective results of 12.4% to 23.5%. The prevalence of positive-IGRA in this study is high. Copyright © 2018 The Author(s).

    Intestinal schistosomiasis is prevalent in East Africa including Ethiopia. Constructed five years back, Gilgel Gibe dam is suspected to harbor the intermediate host for transmission of schistosomiasis. The objective of this study was to determine the prevalence of intestinal schistosomiasis and risk factors among school children. A comparative cross-sectional study was carried out in October 2008 in four Woredas bordering Gilgel Gibe dam, within 10 kilometers, and Bulbul, which is 30 Kms away from the dam. Children attending grades 1-8 in the schools located adjacent to the dam constituted the cases and those living in Bulbul constitute the controls. Using Epinfo version 6.0 for cross-sectional study, a sample size of 937 was determined. Sample size allocation was done 2:1 for cases and control. After interview, stool sample was collected and analyzed. Screening for the presence of intermediate host and physiochemical analyses of selected water bodies along the major water contact sites of the reservoir was also done Data were entered into computer and analyzed using SPSS for windows version 13.0.1. Out of 624 sampled cases and 312 controls, 585 and 270 participated in the study giving a response rate of 93.8% and 86.5%, respectively. Four hundred seventy four (81.0% of the cases and 203 (75.2%) controls use latrine regularly. On stool examination, 406 (47.5%) children, 295 (50.4%) cases and 111 (41.1%) controls) were positive to intestinal parasites but only two children, both from the control groups, were positive for Schistosoma mansoni. The three river water samples on which malacological survey was done had similar physicochemical characteristics in many ways except high conductivity, pH and percent of dissolved oxygen concentration (milligram per liter) at one site where uninfected Biomphilaria Pfeifferi was found The study revealed that schistosomiasis is not yet a problem at Gilgel-Gibe dam.

    This study looks at the changes in injuries after the implementation of a new rule by the International Boxing Association (AIBA) to remove head guards from its competitions. A cross-sectional observational study performed prospectively. This brief report examines the removal of head guards in 2 different ways. The first was to examine the stoppages due to blows to the head by comparing World Series Boxing (WSB), without head guards, to other AIBA competitions with head guards. Secondly, we examined the last 3 world championships: 2009 and 2011 (with head guards) and 2013 (without head guards). World Series Boxing and AIBA world championship boxing. Boxers from WSB and AIBA world championships. The information was recorded by ringside medical physicians. Stoppages per 10 000 rounds; stoppages per 1000 hours. Both studies show that the number of stoppages due to head blows was significantly decreased without head guards. The studies also showed that there was a notable increase in cuts. Removing head guards may reduce the already small risk of acute brain injury in amateur boxing.

    Adolescent suicide rates (ASR) are a matter of concern worldwide. Causes of this trend are not understood and could correspond to socioeconomic factors such as inequality. To investigate sociodemographic variables related to ASR, particularly the potential association with indicators of socioeconomic inequality. Cross-sectional ecological study analyzing data from 29 health districts with univariate and multivariable multilevel Poisson models. ASR were higher in male adolescents and at increasing age. No association was found between ASR and inequality (Gini coefficient and 20/20 ratio). Analysis revealed that living in a single-parent family is associated with ASR. The usual demographic patterns of adolescent suicide apply in Chile. An emerging variable of interest is single-parent family. No cross-sectional association between social inequality and ASR was found based on conflicting evidence. These results should be explored in future prospective population studies to further understand associated social factors.

    Fathers play an important role in the childbearing process, but are sometimes sidelined by midwives. The objectives were: identify fathers' needs during the labor and childbirth process; determine if their needs were met by midwives; and identify variables influencing these needs. The questionnaire was designed based on a systematic literature search and validated by a multistage consensus method. Data were collected during a cross-sectional study in two maternity wards in Belgium, where a medical-led model is used. Fathers present during natural childbirth were recruited via consecutive sampling. Based on multivariate analyses, fathers with a higher education level and multiparous fathers needed less information about the process of birth compared to less educated fathers (pfathers (pfathers, a tour of the delivery room was less important than for primiparous fathers (p=0.005; OR=0.14; 95% CI=0.03-0.54). Married fathers needed less information on how to support their partners physically (pfathers. Information needs are more important to fathers compared to needs focusing on the birth experience or their involvement. Socio-demographic variables like educational level, parity, and marital status were associated with fathers' needs. Midwives need to be aware of fathers' needs during the birth process and to fulfill these needs appropriately. Copyright © 2016 Australian College of Midwives. Published by Elsevier Ltd.

    Full Text Available Yoga, a mind-body activity that requires attentional engagement, has been associated with positive changes in brain structure and function, especially in areas related to awareness, attention, executive functions and memory. Normal aging, on the other hand, has also been associated with structural and functional brain changes, but these generally involve decreased cognitive functions. The aim of this cross-sectional study was to compare brain cortical thickness (CT in elderly yoga practitioners and a group of age-matched healthy non-practitioners. We tested 21 older women who had practiced hatha yoga for at least 8 years and 21 women naive to yoga, meditation or any mind-body interventions who were matched to the first group in age, years of formal education and physical activity level. A T1-weighted MPRAGE sequence was acquired for each participant. Yoga practitioners showed significantly greater CT in a left prefrontal lobe cluster, which included portions of the lateral middle frontal gyrus, anterior superior frontal gyrus and dorsal superior frontal gyrus. We found greater CT in the left prefrontal cortex of healthy elderly women who trained yoga for a minimum of 8 years compared with women in the control group.

    To explore the difference in carotid intima-media thickness (CIMT) between postmenopausal women with and without osteoporosis and the risk of elevated CIMT and plaque presentation. A cross-sectional study was conducted including 46 postmenopausal women with osteoporosis and 45 non-osteoporotic postmenopausal women. CIMT was measured using B-mode ultrasound. There was no statistically significant difference in mean CIMT between postmenopausal women with osteoporosis and those without osteoporosis (p > 0.05). Risk for elevated CIMT in the osteoporosis group was comparable to that of the non-osteoporosis group (adjusted odds ratio = 0.844; 95% confidence interval 0.11-6.45). The risk for the presence of plaque was three times higher in osteoporotic women than in normal individuals. However, after adjusting for age and underlying diseases that would predispose the women to cardiovascular disease, there was no significant difference in terms of presence of plaque between the two groups (adjusted odds ratio = 0.844; 95% confidence interval 0.11-6.45). There was no difference in mean CIMT between postmenopausal women with and without osteoporosis. Risk of elevated CIMT in postmenopausal women with osteoporosis was comparable to that of postmenopausal women without osteoporosis. There was no significant difference between the two groups in terms of the presence of plaque.

    Diagnosing and treatment of premenstrual syndrome (PMS) still pose a challenge in the routine medical practice which usually focuses on single pharmacological therapy. Recent research suggests that the combination of treatments including complementary alternative medicine (CAM) therapies may be more beneficial. The objective of this study was to assess the percentage of diagnosed and nondiagnosed PMS/premenstrual dysphoric disorder (PMDD) based on the presence of adequate symptoms and to compare population using hormonal or pharmaceutical agents versus CAM therapies. This is a cross-sectional study targeting sample population of 160 females of potentially reproductive age done in Ukraine between May 2014 and April 2015. According to declared symptoms, 29% females versus 26% previously diagnosed by a medical professional qualify for "moderate/severe PMS," P > 0.05. In 30% persons using pharmacological agents, major side effects, namely, nausea, insomnia, headache was caused by painkillers, contraceptives, and antidepressants. Only 37.5% of study population has been using CAM therapy methods to deal with the symptoms of PMS. Of these, 22% have achieved moderate degree in relief of the symptoms long term. We have concluded that when dealing with the burden of PMS/PMDD, the affected treatment-seeking women should have choice and access to the variety of therapies within integrative medicine (both conventional and nonconventional).

    Full Text Available Background: The relationship between breastfeeding and postpartum depression is bidirectional. Breastfeeding improves the maternal and neonatal health. There is now growing evidence that it might play a role in the prevention of postpartum depression. Objective: This study explores the relationship between breastfeeding and maternal postpartum depression. It also estimates the prevalence rate of postpartum depression among Saudi women. Methods: This is a cross-sectional study. Three-hundred postpartum women were recruited for this study from various hospitals in the Eastern Province of Saudi Arabia. Likelihood of depression was assessed using the Edinburgh Postpartum Depression Scale (EPDS. Socio-demographic data were collected as well as data regarding breastfeeding duration and intention to breastfeed. Data analysis was done using SPSS version 21, using parametric tests; independent t-test and One-Way ANOVA. Results: Postpartum mothers who intended to breast-feed their babies had a lower EPDS scores compared with those who did not intend to breast-feed. No correlation was found between the duration of breastfeeding and EPDS scores. Prevalence rate of postpartum depression in our sample was 14%. Greater age, having previous babies, intention to breastfeed and vaginal delivery were significantly associated with actual breastfeeding. Conclusion: Screening for mothers in the early postpartum period is essential to detect those who are at risk for postpartum depression. Breastfeeding may help to reduce and prevent the appearance of symptoms of depression. Prevalence rate of postpartum depression in Saudi Arabia, 14%, is similar to the worldwide rate.

    Aim The present study examined whether social support, informal socializing and social participation are associated with glycemic control in older people. Methods Data for this population-based cross-sectional study was obtained from the Japan Gerontological Evaluation Study (JAGES) 2010 linked to the annual health check-up data in Japan. We analyzed 9,554 individuals aged ≥65 years without the certification of needed long-term care. Multivariate logistic regression models were used to assess the effect of social support, informal socializing and social participations on glycemic control. The outcome measure was HbA1c ≥8.4%. Results 1.3% of the participants had a level of HbA1c over 8.4%. Better glycemic control was significantly associated with meeting with friends one to four times per month (odds ratio [OR] 0.51, 95% confidence interval [CI]0.30–0.89, compared to meeting with friends a few times per year or less) and participation in sports groups (OR 0.50, 95% CI 0.26–0.97) even after adjusting for other variables. Meeting with friends more than twice per week, receiving social support, and being married were not associated with better control of diabetes. Conclusions Meeting with friends occasionally is associated with better glycemic control among older people. PMID:28060887

    The use of nutritional supplements (NS) places athletes at great risk for inadvertent doping. Due to the paucity of data on supplement use, this study aimed to determine the proportion of Ugandan athletes using nutritional supplements and to investigate the athletes' motivation to use these supplements. A cross-sectional study was conducted in which an interviewer-administered questionnaire was used to collect data from 359 professional athletes participating in individual (boxing, cycling, athletics) and team (basketball, rugby, football, netball, and volleyball) sports. The data were categorized, and a Chi-square test was used for statistical analysis. Of the 359 athletes, 48 (13.4%) used nutritional supplements. Carbohydrate supplements, energy drinks, vitamin and mineral supplements, fish oils, and protein supplements were the most common supplements used by athletes. NS use was significantly more common among athletes who played rugby and basketball ( X 2 = 61.101, p sport for 5-10 years ( X 2 = 7.460, p = 0.024), and athletes who had attained a tertiary education ( X 2 = 33.377, p performance and health. Compared to NS use by athletes elsewhere, NS use among Ugandan athletes was low. However, determinants of athlete NS use in the current study (category of sport and duration of time spent playing the sport) are similar to those reported elsewhere.

    Several potential dietary trigger factors for migraine have been proposed. However, few studies have examined the intake pattern of these dietary items compared to adequate control populations and whether intake levels may vary by migraine aura status or attack frequency. We conducted a cross-sectional study among participants in the Women's Health Study. We used logistic regression to evaluate the association between migraine and headache status and low intake of foods commonly reported to affect migraine. A total of 25,755 women reported no history of migraine or headache, 5573 reported non-migraine headache and 7042 reported any migraine. Those with non-migraine headache or any migraine were more likely to have low intake of total alcohol (OR = 1.22, 95% CI:1.14-1.29 and OR = 1.17, 95% CI:1.11-1.24, respectively). Migraineurs with aura were more likely to have low intake of chocolate, ice cream, hot dogs, and processed meats. Those who experience migraine at least once per week were more likely to have low intake of skim/low-fat milk and white and red wine. Intake of most suggested migraine dietary triggers differs by migraine aura status and attack frequency, a pattern not found for non-migraine headache. © International Headache Society 2014.

    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.

    The total nuclear reaction cross-section for p - 4 He in the energy range from 25 to 1000 MeV is calculated within Glauber and modified Glauber models. The modified Glauber model is introduced via both Coulomb trajectory of the projectile and calculation of the effective radius of interaction. The effects of density dependent total cross-section and phase variation of nucleon-nucleon scattering amplitude are studied. It is pointed out that the phase variation of the nucleon-nucleon amplitude plays a significant role in describing σR at E p 2 at e = e0 = 0 and γ=2fm 2 at e = e0 = 0.17fm -3 .

    A numerical study of the nonviscous flow characteristics in the cross-sectional planes of a radial inflow turbine scroll is presented. The velocity potential is used in the formulation to determine the flow velocity in these planes resulting from the continuous mass discharge. The effect of the through flow velocity is simulated by a continuous distribution of source/sink in the cross-section. A special iterative procedure is devised to handle the solution of the resulting Poisson's differential equation with Neumann boundary conditions in a domain with generally curved boundaries. The analysis is used to determine the effects of the radius of curvature, the location of the scroll section and its geometry on the flow characteristics in the turbine scroll.

    Mobile phones are commonly used by adolescents. The aim of this study was to clarify associations between duration of mobile phone use and psychological mood in high school students. This cross-sectional study included 2,785 high school students in Niigata, Japan. A self-administered questionnaire was used to elicit information on sex, school year, hours of mobile phone use, psychological mood status, and possible confounders. Psychological mood outcomes were evaluated with the Mood Inventory, developed and validated in 1994, which includes five subcomponents with total scores ranging from 8 to 32 (higher score indicates stronger feeling): "Tension and excitement," "Refreshing mood," "Fatigue," "Depressed mood," and "Anxious mood." Analysis of covariance with Bonferroni's multiple comparison was used to compare mean values among quartiles of hours of mobile phone use. Among the respondents, mean mobile phone use per week was 24 (median 18) h. Long-duration mobile phone use was associated with female students, no participation in sports club activities, early mobile phone use, and fewer hours spent sleeping (all P mobile phone use and total scores were significant for "Depressed mood" (P for trend = 0.005), "Tension and excitement" (P for trend mobile phone use were significantly higher than for other quartiles (all P mobile phone use is associated with unfavorable psychological mood, in particular, a depressed mood.

Night and rotating shift work schedules exert adverse effects on functions of the human body by disturbing circadian rhythms, and they are known to cause sleep disturbances and insomnia. In this paper, we investigate the possible association between shift work and RLS. Methods This cross sectional study was conducted in an automobile manufacturing factory in Tehran, Iran. A total of 780 male assembly workers were recruited in three groups, each with 260 workers: workers on a permanent morning shift (A and two different rotating shift schedules (B and C with morning, afternoon and night shifts. We used the international RLS study group criteria for diagnosis of RLS, and the severity scale for severity assessment in subjects with RLS. Self administered questionnaires were used to gather information on age, smoking, work history, medical condition, and existence and severity of RLS symptoms. Results The prevalence of RLS was significantly higher in rotational shift workers (15% than workers with permanent morning work schedule (8.5%. In workers suffering from RLS, we found greater mean values of age and work experience, higher percentages of drug consumption, smoking, and co-morbid illnesses compared with subjects who did not have RLS, although these differences were statistically significant only for age, work experience and drug consumption. Conclusion Rotational shift work acts as a risk or exacerbating factor for Restless Legs Syndrome.

    Childhood lead poisoning has not made the list of national public health priorities in Lebanon. This study aims at identifying the prevalence and risk factors for elevated blood lead concentrations (B-Pb >or= 100 microg/L) among 1-3 year old children. It also examines the need for universal blood lead screening. This is a cross-sectional study of 281 well children, presenting to the pediatric ambulatory services at the American University of Beirut Medical Center in 1997-98. Blood was drawn on participating children for lead analysis and a structured questionnaire was introduced to mothers asking about social, demographic, and residence characteristics, as well as potential risk factors for lead exposure. Children with B-Pb >or= 100 microg/L were compared to those with B-Pb or= 100 microg/L. Logistic regression analysis showed that elevated B-Pb was associated with paternal manual jobs (odds ratio [OR]: 4.74), residence being located in high traffic areas (OR: 4.59), summer season (OR: 4.39), using hot tap water for cooking (OR: 3.96), exposure to kohl (OR: 2.40), and living in older buildings (OR: 2.01). Lead screening should be offered to high-risk children. With the recent ban of leaded gasoline in Lebanon, emphasis should shift to other sources of exposure in children.

    Obesity is an established risk factor for cancer and cancer-related deaths, including that of the breast. While the prevalence of female obesity has accelerated over the past decade in many developing countries, such as Colombia, the prevalence of overweight and obesity specifically in breast cancer populations has not been fully described. A cross-sectional study including 849 women diagnosed with breast cancer between 2009 and 2014. Based on body mass index, prevalence of overweight (BMI ≥ 25 Colombian breast cancer patients had a prevalence of overweight of 34.28% and obesity of 28.15%. Mean BMI was comparable between premenopausal and postmenopausal women (27.2 versus 27.7, resp.). Among premenopausal women, higher BMI was significantly positively associated with hormone receptor negative tumors, as well as with greater lymphovascular invasion. Colombian breast cancer patients exhibit a significant prevalence of overweight and obesity. Associations of high BMI and poor prognosis variables in the premenopausal population suggest risk of aggressive disease in this population. Future studies to further validate our observations are warranted in order to implement multidisciplinary clinical guidelines.

    Full Text Available Abstract Background Homeless men are highly vulnerable to acquisition of the hepatitis C virus (HCV compared to the general population. In Brazil, a country of continental dimensions, the extent of HCV infection in this population remains unknown. The objective of this study is to investigate the epidemiological profile of exposure to HCV in homeless men in Central Brazil. Methods A Cross-sectional study was conducted in 481 men aged over 18 years attending therapeutic communities specialized in the recovery and reintegration of homeless people. Participants were tested for anti-HCV markers using rapid tests. Poisson regression analysis was used to verify the risk factors associated with exposure to HCV. Results The prevalence of HCV exposure was 2.5% (95.0% CI: 1.4 to 4.3% and was associated with age, absence of family life, injection drug use, number of sexual partners, and history of sexually transmitted infections (STI. Participants reported multiple risk behaviors, such as alcohol (78.9%, cocaine (37.1% and/or crack use (53.1%, and inconsistent condom use (82.6%. Injection drug use was reported by 8.7% of participants. Conclusions The prevalence of HCV infection among homeless men was relatively high. Several risk behaviors were commonly reported, which shows the high vulnerability of this population. These findings emphasize the need for the development of specific strategies to reduce the risk of HCV among homeless men.

    Acne vulgaris has an important genetic predisposition, as well as keratosis pilaris. Clinical observations suggest that patients with keratosis pilaris have less frequent or less severe acne breakouts; however, we found no studies on this regard To determine if the presence of keratosis pilaris is associated with lower prevalence and severity of acne. A cross-sectional study was conducted with dermatology outpatients aged between 14 and 35 years. We evaluated history and clinical grade of acne, demographic variables, history of atopy, smoking, and use of hormonal contraceptives. Two groups were defined by the presence or absence of moderate to severe keratosis pilaris on the arms and were compared by bivariate analysis and by conditional multiple logistic regression. We included 158 patients (66% women), with a median age of 23 ± 11 years. Twenty-six percent of them had keratosis pilaris, which was associated with a history of atopy (odds ratio [OR]=2.80 [1.36 to 5.75]; pkeratosis pilaris had a less frequent history of acne (OR=0.32 [0.14 to 0.70]; pkeratosis pilaris on the arms was associated with lower prevalence of acne vulgaris and lower severity of facial lesions in adolescents and young adults.

    Full Text Available Background: The waste produced in the course of healthcare activities carries a higher potential for infection and injury than any other type of waste. Inadequate and inappropriate knowledge of handling of healthcare waste may have serious health consequences and a significant impact on the environment as well. Objective: The objective was to assess knowledge, attitude, and practices of doctors, nurses, laboratory technicians, and sanitary staff regarding biomedical waste management. Materials and Methods: This was a cross-sectional study. Setting: The study was conducted among hospitals (bed capacity >100 of Allahabad city. Participants: Medical personnel included were doctors (75, nurses (60, laboratory technicians (78, and sanitary staff (70. Results: Doctors, nurses, and laboratory technicians have better knowledge than sanitary staff regarding biomedical waste management. Knowledge regarding the color coding and waste segregation at source was found to be better among nurses and laboratory staff as compared to doctors. Regarding practices related to biomedical waste management, sanitary staff were ignorant on all the counts. However, injury reporting was low across all the groups of health professionals. Conclusion: The importance of training regarding biomedical waste management needs emphasis; lack of proper and complete knowledge about biomedical waste management impacts practices of appropriate waste disposal.

    The aims of this study are a) to examine the prevalence of metabolic syndrome among Filipino-Americans, b) to compare the rate of metabolic syndrome between Filipino men and women, and c) to examine the prevalence of central adiposity. Filipino-Americans are the second largest Asian subgroup in the United States and their leading cause of death is coronary heart disease (CHD). This study utilized a descriptive correlational, cross-sectional design that included a convenience sample of 300 Filipino-Americans residing in Southern Nevada. Survey questionnaires were used to collect the sample's demographic data and presence of CHD risk factors. Waist circumference measurements were used to examine central adiposity. Metabolic syndrome and central adiposity are highly prevalent among Filipino-Americans residing in Southern Nevada. More men than women had the syndrome, but the rate of central adiposity was significantly higher in women than in men. Intensive lifestyle modifications and treatment are indicated to decrease the prevalence of metabolic syndrome and the risk of heart disease in this group. Published by Elsevier Inc.

    The purpose of the study is to explore the reasons why specialist doctors travel to provide regular rural outreach services, and whether reasons relate to (1) salaried or private fee-for-service practice and (2) providing rural outreach services in more remote locations. A national cross-sectional study of specialist doctors from the Medicine in Australia: Balancing Employment and Life (MABEL) survey in 2014 was implemented. Specialists providing rural outreach services self-reported on a 5-point scale their level of agreement with five reasons for participating. Chi-squared analysis tested association between agreement and variables of interest. Of 567 specialists undertaking rural outreach services, reasons for participating include to grow the practice (54%), maintain a regional connection (26%), provide complex healthcare (18%), healthcare for disadvantaged people (12%) and support rural staff (6%). Salaried specialists more commonly participated to grow the practice compared with specialists in fee-for-service practice (68 vs 49%). This reason was also related to travelling further and providing outreach services in outer regional/remote locations. Private fee-for-service specialists more commonly undertook outreach services to provide complex healthcare (22 vs 14%). Specialist doctors undertake rural outreach services for a range of reasons, mainly to complement the growth and diversity of their main practice or maintain a regional connection. Structuring rural outreach around the specialist's main practice is likely to support participation and improve service distribution.

    Full Text Available Social scientists often work with theories of reciprocal causality. Sometimes theories suggest that reciprocal causes work simultaneously, or work on a time-scale small enough to make them appear simultaneous. Researchers may employ simultaneous feedback models to investigate such theories, although the practice is rare in cross-sectional survey research. This paper discusses the certain conditions that make these models possible if not desirable using such data. This methodological excursus covers the construction of simultaneous feedback models using a structural equation modeling perspective. This allows the researcher to test if a simultaneous feedback theory fits survey data, test competing hypotheses and engage in macro-comparisons. This paper presents methods in a manner and language amenable to the practicing social scientist who is not a statistician or matrix mathematician. It demonstrates how to run models using three popular software programs (MPlus, Stata and R, and an empirical example using International Social Survey Program data.

    Comparing habitual nutrient intakes in persons with a history of acute myocardial infarction (AMI), and age-matched controls. Design. Cross-sectional study. Subjects. Men and women (525 cases and 1890 matched controls), aged 47-73 years, of the population-based Malmö Diet and Cancer cohort. Nutrient intakes were assessed by a validated modified diet history method. Body fatness was assessed by bioimpedance analysis. Case ascertainment was provided by national and regional registries. Men and women were analysed separately. Median time since AMI was 5.5 years in men and 3.8 years in women. Cases reported lower energy intakes (EIs) than controls, despite having similar basal metabolic rates. After adjustment for total EI, both male and female cases had lower fat intake and higher intake of several micronutrients, such as ascorbic acid, folate, and vitamin E, than controls, the difference being largest in men. Most of the cases reporting dietary change quoted 'disease' as their main reason for change. They had lower EI and lower energy-adjusted intake of fat than other cases. Survivors of AMI reported dietary habits more in line with current recommendations, particularly those who afterwards reported having changed their dietary habits. The possible bias introduced by social desirability is discussed.

    To investigate estimation of calorie (energy) content of meals from fast food restaurants in adults, adolescents, and school age children. Cross sectional study of repeated visits to fast food restaurant chains. 89 fast food restaurants in four cities in New England, United States: McDonald's, Burger King, Subway, Wendy's, KFC, Dunkin' Donuts. 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. Estimated calorie content of purchased meals. 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). 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.

    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.

    To compare levels of depression, anxiety, and post traumatic stress disorder (PTSD) amongst immigration detainees with a comparison group of asylum seekers living within the community. A cross-sectional questionnaire study. Sixty-seven detained asylum seekers, 30 detainees who had previously been imprisoned within the UK for criminal offences, and 49 asylum seekers living in the community completed the hospital anxiety and depression scale (HADS) and the impact of event scale-revised (IES-R). Demographic information was collected. High levels of anxiety, depression, and PTSD symptoms were reported by all three groups. Detained asylum seekers had higher scores than asylum seekers living within the community for depression, anxiety, and PTSD symptoms. There was an interaction between length of detention period and prior exposure to interpersonal trauma (IP trauma) on depression scores. Immigration detainees are highly vulnerable to psychological distress. A review of detention policies is recommended in light of this. Immigration detention may have an independent adverse effect on mental health. It is also possible that individuals with mental health problems may be more likely to be detained. Further research is required to investigate this.

    A simplified reactor model is used to study the influence of critical β-values on economy parameters and dimensions of possible long time pulsed tokamak reactors. Various betas deduced from stability and equilibrium MHD theory are introduced and put into the scaling in context with technological constraints, as maximum B-field, core constraint, maximum wall loading a.o. The plasma physical concepts treated comprise circular and strongly elongated cross section and approximated FCT equilibria. The computational results are presented as plots of possible economy parameter ranges (magnet energy, wall loading, volumina, investment costs per unit power) dependent on β for suitably chosen hierarchies of the constraints. - A burn time reduction by the build ups of α-pressure may be possible for the pressure profile sensitive high-β equilibria (FCT). Burn times in the 1O sec range, resulting from simple estimates, would about cancel the economic advantages of reactors with high-β equilibria compared to a β = 5% standardreactor (UWMAK I). (orig.)

    Delusional jealousy (DJ) has been described in patients with Parkinson's disease (PD) on dopaminergic therapy, but a role for dopaminergic therapy in DJ has not been established. The current cross-sectional study on DJ investigated its association with dopaminergic therapies compared with their associations with hallucinations and its prevalence in PD patients. Eight hundred five consecutive patients with PD were enrolled between January 2009 and June 2010. DJ was identified in 20 patients (2.48%) and hallucinations in 193 patients (23.98%). In the multivariate logistic regression analyses, dopamine agonists were significantly associated with DJ (odds ratio, 18.1; 95% CI, 3.0-infinity; P = .0002) but not with hallucinations (odds ratio, 0.73; 95% CI, 0.49-1.10; P = .133). These findings suggest that dopamine agonist treatment represents a risk factor for DJ in PD independent of the presence of a dementing disorder, and the presence of this additional nonmotor side effect should be investigated in this clinical population.

    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. Cross sectional, quantitative survey, part interview and part self completion, administered in respondents' homes. North east England. Stratified random sample of 629 young people aged 15 and 16 years who had "opted in" to research through a postal consent procedure. 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 (Pawareness of coupon schemes, brand stretching, and tobacco marketing in general were all independently associated with current smoking status. 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.

    Donepezil hydrochloride is a central acetylcholine esterase inhibitor that is widely used in Alzheimer disease (AD). We have recently observed some differences in lipid profile between occasional cases of Donepezil hydrochloride users (DU) and non-users (DNU). This prompted us to study the levels of plasma lipids in these two groups, cross-sectionally. The medical charts of patients with probable AD were screened for current use of Donepezil hydrochloride and lipids profile, along with other clinical and demographic data. A total number of 105 patients were identified and included in the final analysis. Patients were divided into two groups (DU and DNU). Plasma levels of lipids were recorded. Mann-Whitney or t-test for continuous variables and Fisher exact test for categorical variables were used to test for significant differences between the groups. Regression analysis was applied to identify independently the factors associated with lipid levels. Thirty-three patients were DU and 72 DNU. The two groups differed in terms of age, lipid levels and cognitive level. DU had statistically significant higher levels of triglycerides compared with those not using the drug (P=0.036), higher total cholesterol (Phydrochloride. Alternatively, this may indicate that the effect of the medication may involve lipid metabolism, rather than other proposed mechanisms.

    The daily occupation as a swine breeder involves exposure to several bacterial components and organic dusts and inhalation of a large amount of allergens. To investigate the risk of respiratory diseases and atopy in swine breeders compared with the general population living in the same area. A population-based cross-sectional study was conducted in an agricultural area of northern Italy that enrolled a random sample of resident male breeders and non-breeders. Demographic features, comorbidities, and presence of allergic respiratory disease were retrieved through interview. Prick tests for common allergens were performed. An evaluation of pollen and mold in air samples taken inside and outside some swine confinement buildings also was performed. One hundred one male breeders (78 native-born, mean age ± SD 43.0 ± 11.1 years) and 82 non-breeders (43.0 ± 11.1 years) were enrolled. When restricting the analysis to native-born subjects, breeders vs non-breeders showed a lower prevalence of respiratory allergy (12.8% vs 31.1%, respectively, P = .002), asthma (6.4% vs 15.8%, P = .059), rhinitis (16.7% vs 51.2%, P increase, and might decrease, the risk of pollen sensitization and allergic disease.

    Full Text Available Abstract Background The aim of the study was to investigate the abductor hallucis muscle characteristics, defined as dorso-plantar (DP thickness, medio-lateral (ML width, and cross-sectional area (CSA in relation to the severity of hallux valgus using musculoskeletal ultrasound. One hundred and two feet, mean (SD age of 60.3 (20.54 years old, displaying varying severities of hallux valgus were stratified into four groups representing the four grades of the Manchester Scale (grade 0: no deformity, grade 1: mild deformity, grade 2: moderate deformity and grade 3: severe deformity. Methods The abductor hallucis muscle was imaged in each foot using a portable ultrasound system. The mean (SD DP thickness, ML width, and CSA measurements were compared across the four Manchester Scale grades using a one-way ANOVA. Results Significant differences in DP thickness were found between feet with no hallux valgus (grade 0 and feet with hallux valgus grade 2 (p = 0.001 and 3 (p  0.0125. Conclusions We speculate that morphological changes to the abductor hallucis muscle occur early in the development of the deformity.

    Presence of epithelial desquamation, erythema, and erosions on gingival tissue is usually described in the literature as desquamative gingivitis (DG). A wide range of autoimmune/dermatologic disorders can manifest as DG, although the two more common are oral lichen planus and mucous membrane pemphigoid. The aim of this study is to investigate prevalence of 11 periodontopathogenic microorganisms in patients with DG and to compare it with the microbiologic status of individuals affected by plaque-induced gingivitis (pGI). Cross-sectional clinical and microbiologic data were obtained from 66 patients (33 in each group). Subgingival plaque samples were analyzed using semiquantitative polymerase chain reaction analysis. Statistically significant difference, but with little clinical significance, was observed in gingival conditions between the two groups, probably due to the worse home control hygiene of patients with DG. Prevalence and levels of Aggregatibacter actinomycetemcomitans, Eikenella corrodens, and Fusobacterium nucleatum/periodonticum were statistically higher in samples from patients with DG than in those with pGI. In multivariate regression models, subgingival colonization of A. actinomycetemcomitans and F. nucleatum/periodonticum was not statistically associated with DG, whereas, high levels of E. corrodens were associated with 13-fold increased odds for DG. Microbiologic differences were found in subgingival plaque for patients with DG and pGI. This may suggest possible association between periodontal pathogens and DG.

    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.

    Compare changes in registered nurses' perception of the patient safety culture in restructured and not restructured intensive care units during a four-year period. Two cross-sectional surveys were performed, in 2008/2009 (time 1) and 2012/2013 (time 2). During a period of 0-3 years after time 1, three of six hospitals merged their general and medical intensive care units (restructured). The other hospitals maintained their structure of the intensive care units (not restructured). Intensive care units in hospitals at one Norwegian hospital trust. The safety culture was measured with Hospital Survey on Patient Safety Culture. At times 1 and 2, 217/302 (72%) and 145/289 (50%) registered nurses participated. Restructuring was negatively associated with change in the safety culture, in particular, the dimensions of the safety culture within the unit level. The dimensions most vulnerable for restructuring were manager expectations and actions promoting safety, teamwork within hospital units and staffing. In this study, the restructuring of intensive care units was associated with a negative impact on the safety culture. When restructuring, the management should be particularly aware of changes in the safety culture dimensions manager expectations and actions promoting safety, teamwork within hospital units and staffing.

    Given the wide variations in prevalence of chronic obstructive pulmonary disease observed between populations with similar levels of exposure to tobacco smoke, we aimed to investigate the possibility of variations in prevalence of chronic bronchitis (CB) between two geographically distinct smoking populations in rural Karnataka, India. The Burden of Obstructive Lung Disease (BOLD) questionnaire was administered to all men aged >30 years in a cross-sectional survey. The χ(2) and Fisher's exact tests were used to compare CB prevalence in the two populations. Logistic regression was used to analyse the impact of multiple variables on the occurrence of CB. Two samples of 2322 and 2182 subjects were included in the study. In non-smokers, CB prevalence did not differ between the populations. However, it was significantly different between smoking populations (44.79% vs. 2.13%, P < 0.0001). Logistic regression indicated that, in addition to smoking, region, age, occupational dust exposure and type of house were associated with higher likelihood of CB. An interaction between smoking and area of residence was found (P < 0.001) and appeared to explain the effect of region (without interaction). A significant difference in CB prevalence was observed between male populations from two areas of Karnataka state, including when stratified by smoking status. No significant difference was observed between non-smokers.

    Full Text Available Spallation reactions for the long-lived fission products 137Cs, 90Sr and 107Pd have been studied for the purpose of nuclear waste transmutation. The cross sections on the proton- and deuteron-induced spallation were obtained in inverse kinematics at the RIKEN Radioactive Isotope Beam Factory. Both the target and energy dependences of cross sections have been investigated systematically. and the cross-section differences between the proton and deuteron are found to be larger for lighter fragments. The experimental data are compared with the SPACS semi-empirical parameterization and the PHITS calculations including both the intra-nuclear cascade and evaporation processes.

    Emotional intelligence in nursing is of global interest. International studies identify that emotional intelligence influences nurses' work and relationships with patients. It is associated with compassion and care. Nursing students scored higher on measures of emotional intelligence compared to students of other study programmes. The level of emotional intelligence increases with age and tends to be higher in women. This study aims to measure the differences in emotional intelligence between nursing students with previous caring experience and those without; to examine the effects of gender on emotional intelligence scores; and to test whether nursing students score higher than engineering colleagues on emotional intelligence measures. A cross-sectional descriptive study design was used. The study included 113 nursing and 104 engineering students at the beginning of their first year of study at a university in Slovenia. Emotional intelligence was measured using the Trait Emotional Intelligence Questionnaire (TEIQue) and Schutte Self Report Emotional Intelligence Test (SSEIT). Shapiro-Wilk's test of normality was used to test the sample distribution, while the differences in mean values were tested using Student t-test of independent samples. Emotional intelligence was higher in nursing students (n = 113) than engineering students (n = 104) in both measures [TEIQue t = 3.972; p emotional intelligence scores than male students on both measures, the difference was not statistically significant [TEIQue t = -0.839; p = 0.403; SSEIT t = -1.159; p = 0.249]. EI scores in nursing students with previous caring experience were not higher compared to students without such experience for any measure [TEIQue t = -1.633; p = 0.105; SSEIT t = -0.595; p = 0.553]. Emotional intelligence was higher in nursing than engineering students, and slightly higher in women than men. It was not associated with previous caring experience. Copyright

    Full Text Available Background and Aim: Cardiovascular autonomic function tests (CAFTs are non-invasive tests that can assess both sympathetic and parasympathetic autonomic functions. Autonomic dysfunction may be considered as a risk factor for obesity and vice versa. For measurement of obesity, body mass index (BMI is a simple, valid and inexpensive method. Hence, this study was designed to evaluate the effect of obesity based on BMI criteria on autonomic nervous system based on CAFT in young adult males. Methods: A cross-sectional study was carried out on 43 young adult males in the age group of 18–25 years with an age-matched control (n = 43 group. After initial screening, anthropometric measurements were recorded. CAFTs were performed and recorded by the Cardiac Autonomic Neuropathy Analysis System (CANWin. Unpaired t- test was done to compare the parameters of study and control groups in Microsoft Excel® 2010. Results: Parasympathetic test parameters of study and control groups when expressed in mean ± standard deviation were not found statistically significant (P > 0.05. The fall in systolic blood pressure (BP in orthostatic test of study group (12.19 ± 4.8 mmHg was significantly (P = 0.0001 higher than that of control group (7.33 ± 5.16 mmHg. Increase in diastolic BP in isometric handgrip exercise test of study group (11.84 ± 5.39 mmHg was significantly less (P = 0.004 than that of control group (16.39 ± 8.71 mmHg. Conclusion: Overweight young males have altered sympathetic activity but parasympathetic activity did not show any significant difference when compared to normal weight males.

    Full Text Available CONTEXT AND OBJECTIVE Sodium excretion abnormalities in preeclampsia have been studied in relation to several factors. The objective of this study was to compare natriuria (mEq/24 h and calciuria levels (mg/24 h in preeclamptic patients. DESIGN AND SETTING An analytical cross-sectional study with a control group was conducted in the obstetric center and the high-risk pregnancy outpatient clinic at a university hospital in southern Brazil, and in a primary healthcare unit in the same city, including pregnant women with mild preeclampsia, severe preeclampsia or chronic hypertension, and women with normal pregnancies (14 patients in each group. METHOD Natriuria was measured using an ion-selective electrode in an automated clinical chemistry analyzer (Hitache 917, Roche. All the patients collected 24-hour urine, at home or at the hospital, for analysis of proteins, creatinine, calcium, sodium and uric acid. Quantitative variables with asymmetrical distribution were described using the median, minimum and maximum, and were compared using the Kruskal-Wallis test. The results were logarithmically transformed, with one-way analysis of variance (ANOVA by ranks and then the post-hoc Tukey test, and were analyzed by means of the Spearman correlation and receiver operating characteristic (ROC curve. The significance level used was 0.05. RESULTS There were significant differences between the groups in comparing severe preeclampsia with chronic hypertension and severe preeclampsia with controls (P < 0.0001 for both measurements. CONCLUSION Natriuria levels may be lower in preeclampsia when associated with calciuria. Natriuria assessment is an additional test for differential diagnosis of hypertensive diseases in pregnancy, but is a poor predictor when used alone.

    Full Text Available Abstract Background Nutrition clubs (NC operate in community settings and provide members with nutrition education and meal replacements for weight management. NC are owned and operated by distributors of Herbalife products. There are over 6200 NC in the US, but there has been no independent assessment of the association of these NC with biomarkers of health. Methods We conducted a cross-sectional pilot study to compare the health status of 100 NC members to 100 community-matched controls (CC in the greater Boston area. Each CC was matched to a NC member for community of residence (zip code, age category, gender, BMI category, race/ethnicity, education level (category, and readiness to make health changes. Measures obtained included cardio-metabolic risk factors, body composition, markers of nutritional status, reported health status, dietary intake, physical activity, sleep and depression. Results Participants were predominantly female (64% and Hispanic (73%. NC members had significantly lower fasting insulin (P < 0.001 and lower HbA1c (P = 0.008, higher levels of 25 hydroxy-vitamin D (P = 0.001, and vitamin E:cholesterol ratio (P < 0.001, and lower prevalence of metabolic syndrome (P = 0.02 compared to CC. In addition, most of the NC members (99% were satisfied with Herbalife NC membership for themselves and their families. A higher percentage of NC members (86% compared to CC (32% reported being in much better or somewhat better health compared to a year ago (P < 0.001; and they reported significantly better physical health (P = 0.03, and fewer sleep problems (P = 0.03. Conclusion Herbalife NC membership was positively associated with perceived health and measured cardiometabolic benefits. However, causality cannot be inferred from these findings.

    To evaluate the frequency, severity, and associations of symptoms of attention-deficit/hyperactivity disorder (ADHD) in children with narcolepsy with and without cataplexy. Cross-sectional survey. Four French national reference centers for narcolepsy. One hundred eight consecutively referred children aged younger than 18 y with narcolepsy, with (NwC, n = 86) or without cataplexy (NwoC, n = 22), and 67 healthy controls. The participants, their families, and sleep specialists completed a structured interview and questionnaires about sleep, daytime sleepiness, fatigue, and ADHD symptoms (ADHD-rating scale based upon Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision [DSM-IV-TR] symptoms), and use of psychostimulants for the treatment of narcolepsy (administered in 68.2%). Polysomnographic measures were collected. Clinically significant levels of ADHD symptoms were found in 4.8% of controls compared with 35.3% in patients with NwoC (P ADHD scores were 6.4 (95% confidence interval [CI]: 4.5, 9.0) in controls compared with 14.2 (95% CI: 10.6, 18.9; P hyperactivity/impulsivity were also significantly higher in both narcolepsy groups compared with controls. No difference was found between the NwC and NwoC groups for any ADHD measure. ADHD symptom severity was associated with increased levels of sleepiness, fatigue, and insomnia. Compared with the 34 untreated patients, the 73 patients treated with psychostimulants (modafinil in 91%) showed a trend toward lower narcolepsy symptoms but not lower ADHD symptoms. Pediatric patients with narcolepsy have high levels of treatment-resistant attention-deficit/hyperactivity disorder (ADHD) symptoms. The optimal treatment for ADHD symptoms in these patients warrants further evaluation in longitudinal intervention studies. © 2015 Associated Professional Sleep Societies, LLC.

    We present an atomically resolved study of metal-organic vapor epitaxy grown Mn doped InSb. Both topographic and spectroscopic measurements have been performed by cross-sectional scanning tunneling microscopy (STM). The measurements on the Mn doped InSb samples show a perfect crystal structure without any precipitates and reveal that Mn acts as a shallow acceptor. The Mn concentration of the order of ∼10 20  cm −3 obtained from the cross-sectional STM data compare well with the intended doping concentration. While the pair correlation function of the Mn atoms showed that their local distribution is uncorrelated beyond the STM resolution for observing individual dopants, disorder in the Mn ion location giving rise to percolation pathways is clearly noted. The amount of clustering that we see is thus as expected for a fully randomly disordered distribution of the Mn atoms and no enhanced clustering or second phase material was observed

    Full Text Available ABSTRACT Objectives: to compare the pelvic floor muscle strength in primiparous women after normal birth and cesarean section, related to the socio-demographic characteristics, nutritional status, dyspareunia, urinary incontinence, perineal exercise in pregnancy, perineal condition and weight of the newborn. Methods: this was a cross-sectional study conducted after 50 - 70 postpartum days, with 24 primiparous women who underwent cesarean delivery and 72 who had a normal birth. The 9301 PeritronTM was used for analysis of muscle strength. The mean muscle strength was compared between the groups by two-way analysis of variance. Results: the pelvic floor muscle strength was 24.0 cmH2O (±16.2 and 25.4 cmH2O (±14.7 in postpartum primiparous women after normal birth and cesarean section, respectively, with no significant difference. The muscular strength was greater in postpartum women with ≥ 12 years of study (42.0 ±26.3 versus 14.6 ±7.7 cmH2O; p= 0.036 and in those who performed perineal exercises (42.6±25.4 11.8±4.9 vs. cmH2O; p = 0.010, compared to caesarean. There was no difference in muscle strength according to delivery type regarding nutritional status, dyspareunia, urinary incontinence, perineal condition or newborn weight. Conclusion: pelvic floor muscle strength does not differ between primiparous women based on the type of delivery. Postpartum women with normal births, with higher education who performed perineal exercise during pregnancy showed greater muscle strength.

    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.

    Sleep disorders are common and associated with multiple metabolic and psychological derangements. Obstructive sleep apnoea (OSA) is among the most common sleep disorders and an inter-relationship between OSA, insulin resistance, obesity, type 2 diabetes (T2DM) and cardiovascular diseases has been established. Prevalence of sleep disorders in Kenyans, particularly in individuals with T2DM is unknown. We thus aimed to determine prevalence of poor quality of sleep (QOS) and high risk for OSA, among persons with T2DM and determine their associations with socio-demographic and anthropometric variables. Utilising a Cross- Sectional Descriptive design, QOS and risk for OSA were determined in a randomly selected sample of patients with T2DM (cases) and an age and sex matched comparison group. The validated Pittsburgh Sleep Quality Index (PSQI) and Berlin Questionnaire (BQ) were used to measure QOS and risk for OSA respectively. Associations between poor QOS, high risk for OSA, and socio-demographic and anthropometric variables in cases were evaluated. From 245 randomly selected persons with T2DM attending outpatient clinics, aged over 18 years, 22 were excluded due to ineligibility thus 223 were included in the analysis; 53.8% were females, mean age was 56.8 (SD 12.2) years and mean BMI was 28.8 kg/m 2 (SD 4.4). Among them, 119 (53%, CI 95% 46.5-60.2) had poor QOS and 99 (44% CI 95% 37.8-50.9) were at high risk for OSA. Among 112 individuals in comparison group, 33 (29.5%, CI 95% 20.9-38.3) had poor QOS and 9 (8%, CI 95% 3.3-13.4) had high risk for OSA. Cases had a significantly higher probability for poor QOS [OR 2.76 (95% CI 1.7-4.4))] and high risk for OSA [OR 9.1 (95% CI 4.4-19.0)]. Higher waist circumference was independently associated with a high risk for OSA in cases. We demonstrate a high burden of sleep disturbances in patients with T2DM. Our findings may have implications for clinicians to screen for sleep disorders when assessing patients with T2DM and

    2015-12-01

    Full Text Available INTRODUCTION Optimal Infant and Young Child-Feeding (IYCF practices are crucial for nutritional status, growth, development, health, and ultimately the survival of infants and young children. It was estimated that, if 90% of infants are covered with a package of intervention to protect, promote, and support the optimal IYCF practices, almost one-fifth of overall under-five mortality can be averted. OBJECTIVES 1. To study the socio-demographic characteristics of the Infants and Young children living in the rural areas. 2. To study the core Infant and Young Child Feeding indicators. MATERIALS AND METHODS A cross-sectional observational study was conducted in Venigandla village, the rural field practice area of NRI Medical College, Guntur, for a period of 4 months from January to April 2015. A total of 100 children aged 6-23 months were studied using a pre-tested semi-structured schedule. Data were entered in Microsoft Excel and analysed using Epi Info software. RESULTS Of the 100 children studied, majority of families belong to lower middle class (40% according to BG Prasad socio- economic classification. One in 10 children was given pre- lacteal feeds after birth. Two-thirds of mothers breastfed their children within first hour after birth. Three fourths of children received exclusively breastfed up to 6 months of age. Minimum Dietary Diversity was observed in 74%, Minimum Meal Frequency observed in 94% and Minimum Acceptable Diet was observed in 70% of the 6-23 months children. CONCLUSION The IYCF practices were observed to be better in the present study when compared to similar studies done elsewhere in the country. Area specific programmes need to be created for providing comprehensive nutrition and health education for mothers, to protect, promote and sustain the optimal IYCF practices.

    Obesity exhibits a wide variety of electrocardiogram (ECG) abnormalities in adults, which often lead to cardiovascular events. However, there is currently no evidence of an association between obesity and ECG variables in children and adolescents. The present study aimed to explore the associations between obesity and ECG intervals and axes in children and adolescents. A cross-sectional observational study of 5,556 students aged 5-18 years was performed. Anthropometric data, blood pressure and standard 12-lead ECGs were collected for each participant. ECG variables were measured manually based on the temporal alignment of simultaneous 12 leads using a CV200 ECG Work Station. Overweight and obese groups demonstrated significantly longer PR intervals, wider QRS durations and leftward shifts of frontal P-wave, QRS and T-wave axes, while the obese group also demonstrated significantly higher heart rates, compared with normal weight groups within normotensive or hypertensive subjects (Pobesity was also associated with longer PR intervals, wider QRS duration and a leftward shift of frontal ECG axes compared with normal waist circumference (WC) within normotensive or hypertensive subjects (Paffecting the ECG variables. Furthermore, the ECG variables, including PR interval, QRS duration and frontal P-wave, QRS and T-wave axes, were significantly linearly correlated with body mass index, WC and waist-to-height ratio adjusted for age, gender, ethnicity and blood pressure. However, there was no significant association between obesity and the corrected QT interval (P>0.05). The results of the current study indicate that in children and adolescents, general and abdominal obesity is associated with longer PR intervals, wider QRS duration and a leftward shift of frontal P-wave, QRS and T-wave axes, independent of age, gender, ethnicity and blood pressure.

    There has been an increase in the prevalence of overweight and obesity in adolescents and young adults, especially in men than women. Many adolescents have a sedentary lifestyle and consume more processed, low-fiber foods. The aim of this study was to assess the frequency of fiber intake and its selected dietary source consumption in relation to the overweight among Polish male students. This cross-sectional study involved 1,233 male students aged 13.0-24.9 years from northern, eastern and central Poland. The respondents completed a self-administered Block Screening Questionnaire for Fruit/Vegetable/Fiber Intake and measurements of their body mass and height were performed. The overweight and obesity prevalence was assessed using international standards. The most frequently consumed foods by students included: white bread and potatoes, fruit and fruit or vegetable juices. The odds of overweight (including obesity) were lower from 28% (OR=0.72; 95%CI:0.56-0.93) to 31% (OR=0.69; 95%CI:0.50-0.95) with a daily consumption of white bread compared to non-daily consumption of white bread. Consumption ≥4 times/week of prepared vegetables (cooked, preserved or marinated) was associated with 51% lower odds of overweight (OR=0.49; 95%CI:0.27-0.97) compared to consumption less than 4 times/week of these foods. The odds of overweight for the level of fiber intake was insignificant. This study provides surprising insights regarding high-fiber and low-fiber food consumption and overweight in Polish male students. A lower odds of overweight was associated with a higher frequency consumption of relatively low in fiber foods as white bread and cooked, preserved or marinated vegetables. Most of the students consumed fiber at an unacceptable level, so a beneficial impact of high-fiber foods on overweight prevalence was not shown.

    It is well known that consumption of isoflavones reduces the risk of cardiovascular disease. However, the effectiveness of isoflavones in preventing dementia is controversial. A number of intervention studies have produced conflicting results. One possible reason is that the ability to produce equol, a metabolite of a soy isoflavone, differs greatly in individuals. In addition to existing data, we sought to confirm whether an apparent beneficial effect in cognitive function is observed after soy consumption in equol producers compared with non-producers. The present study was a cross-sectional, observational study of 152 (male/female = 61/91, mean age 69.2 ± 9.2 years) individuals. Participants were divided into two groups according to equol production status, which was determined using urine samples collected after a soy challenge test. Cognitive function was assessed using two computer-based questionnaires (touch panel-type dementia assessment scale [TDAS] and mild cognitive impairment [MCI] screen). Overall, 60 (40%) of 152 participants were equol producers. Both TDAS and prevalence of MCI were significantly higher in the equol producer group than in the non-producer group. In univariate analyses, TDAS significantly correlated with age, serum creatinine, estimated glomerular filtration rate and low-density lipoprotein cholesterol. In multiple regression analysis using TDAS as a dependent variable, equol producer (β = 0.236, P = 0.005) was selected as an independent variable. In addition, multiple logistic regression analysis to assess the presence of MCI showed that being an equol producer was an independent risk factor for MCI (odds ratio 3.961). Compared with equol non-producers, equol producers showed an apparent beneficial effect in cognitive function after soy intake.

    Stunting indicates failure to attain genetic potential for height and is a well-documented indicator for poor growth. Depression is common in women of reproductive age and women's mental health problems may affect the growth of young children. We examined the association between maternal depression and stunting in mother-child pairs attending Child Welfare Clinic (CWC) in Northern Ghana. An analytical cross-sectional study was performed involving mothers (15-45 years) and their children (0-59 months) who attended CWC at Bilpeila Health Centre, Tamale, Ghana. Socio-demographic data were collected using a semi-structured questionnaire, maternal depression was measured using Centre for Epidemiological Studies Depression Screening Scale, and anthropometry was conducted on children following standard procedures. The association between maternal depression and child stunting was examined in logistic regression adjusting for potential confounders. Prevalence rates of child stunting and maternal depression were estimated at 16.1 and 27.8 % respectively in Northern Ghana. Mothers with depression when compared with those without depression tended to be younger, be currently unmarried, belong to the poorest household wealth tertile, and were more likely to have low birth weight babies, so these characteristics were adjusted for. In an adjusted multivariate logistic regression model, children of depressed mothers were almost three times more likely to be stunted compared to children of non-depressed mothers (Adjusted OR = 2.48, 95 % CI 1.29-4.77, p = 0.0011). There is a high prevalence of depression among mothers in Northern Ghana which is associated with child stunting. Further studies are needed to identify the determinants of maternal depression and to examine its association with child stunting to inform nutrition programming.

    Full Text Available Abstract Background In Jordan, as in neighboring countries in the Middle East, higher education and higher employment rates in recent years among women have had an impact on traditionally based infant feeding. The objective of this study was to evaluate practice, knowledge and attitude to breastfeeding and to assess factors associated with breastfeeding among women in the north of Jordan. Methods A cross sectional study was carried out between 15 July 2003 and 15 August 2003. A total of 344 women with children aged between 6 months and 3 years from five different villages in the north of Jordan were randomly selected and interviewed. Information regarding participants' demographics, infant feeding in first six months of life, knowledge and attitude towards breastfeeding was collected. Results Full breastfeeding was reported by 58.3%, mixed feeding was reported by 30.3% and infant formula feeding was reported by 11.4%. Almost one third of the full breastfeeding group did so for 6–12 months, and almost two thirds did continue breastfeeding for more than one year. Employed women were more likely not to practice full breastfeeding compared to unemployed women (odds ratio 3.34, 95% CI 1.60, 6.98, and women who had caesarian delivery were more likely not to practice full breastfeeding compared to those who had vaginal delivery (odds ratio 2.36, 95% CI 1.17, 4.78. Jordanian women had a positive attitude but work place and short maternity leaves had a negative impact on breastfeeding. Conclusion This study showed that a high proportion of Jordanian women did breastfeed for more than one year. However, working women and those who deliver by caesarean section were less likely to breastfeed. It is speculated that adopting facilitatory measures at hospitals and work place could increase the rate of full breastfeeding.

    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.

    Full Text Available Objectives: This study aimed to identify the prevalence of gestational diabetes mellitus (GDM and to examine its associations with social and behavioral factors, maternal body mass index (BMI, anemia, and hypertension. Methods: A cross-sectional analysis was performed on data collected from 2345 pregnant women from 16 hospitals in five selected provinces in mainland China. Results: Prevalence of GDM was as follows: overall: 3.7%; pregnant women in the first pregnancy: 3.4%; pregnant women in the second pregnancy: 4.6%. Compared with early pregnancy women, late-stage pregnant women were more likely to have GDM (OR = 4.32, 95% CI (1.82, 10.27. Compared with 18–25 years old pregnant women, women aged 36–45 years were more likely to have GDM (OR = 3.98, 95% CI (1.41, 11.28. Compared with non-hypertensive patients, hypertensive patients were more likely to have GDM (OR = 6.93, 95% CI (1.28, 37.64. However, second pregnancy, high maternal BMI, prolonged screen time (TV-viewing time, computer-using time, and mobile-phone using time, insufficient and excessive sleep duration, poor sleep quality, smoking, and secondhand smoke exposure were not significantly associated with an increased risk of GDM. Conclusions: Women in the second pregnancy do not appear to predict an increased risk for developing GDM than women in the first pregnancy. High-risk groups of GDM included women in their late pregnancy, aged 36–45 years old, and with hypertension. The findings will contribute to an improved understanding of social and behavioral determinants of GDM in Chinese population and contribute to the development of health-prevention promotion interventions to address GDM.

    Full Text Available Objectives. To investigate the experience of suicidal expressions (death wishes, life weariness, ideation, plans and attempts in young Swedish Sami, their attitudes toward suicide (ATTS, and experience of suicidal expressions and completed suicide in significant others and to compare with Swedes in general. Methods. A cross-sectional study comprising 516 Swedish Sami, 18–28 years of age together with an age and geographically matched reference group (n=218. Parts of the ATTS questionnaire have been used to cover different aspects of the suicidal complex.Data were analysed with regard to gender, occupation, counties and experience of negative societal treatment due to Sami background. Results. Both young Sami and young Swedes reported suicidal ideation, life weariness, and death wishes in a high degree (30–50%, but it was more common among the Sami. Having had plans to commit suicide showed a significant gender difference only in the Sami. The prevalence of suicide attempts did not differ significantly between Sami and Swedes. Subgroups of the Sami reported a higher degree of suicidal behaviour, Sami women and reindeer herders reported a 3, 5-fold higher odds of suicide attempts and a 2-fold higher odds having had plans committing suicide. Sami living in Vasterbotten/Jamtland/Vasternorrland and Sami with experience of ethnicity related bad treatment 2-fold higher odds of suicidal plans compared to those living in other counties. Conclusion. An increased occurrence of suicidal ideation/death wishes/life weariness in young Sami compared to young majority Swedes was found, but not an increased prevalence of suicide attempts and positive attitudes together with an increased awareness to handle suicide problems could be a contributing factor. Severe circumstances and experience of ethnicity-related bad treatment seems to contribute to increased levels of suicidal plans and attempts in subgroups of Sami.

    Simultaneous performances of motor and attention-demanding tasks are common in activities of everyday life. The present cross-sectional study examined the changes and age-related differences on mobility performance with an additional cognitive or motor task, and evaluated the relative dual-task cost (DTC) on the motor performance in young, middle-aged and older women. A total of 30 young (mean age 25.12 ± 3.00 years), 30 middle-aged (mean age 47.82 ± 5.06 years) and 30 older women (mean age 72.74 ± 5.95 years) were recruited. Participants carried out: (i) single task: Timed Up & Go Test; (ii) cognitive dual-task: Timed Up & Go Test while counting backwards by three; (iii) manual dual-task: Timed Up & Go Test while carrying a glass of water. A repeated measures anova with between-factor as age groups and within-factor as tasks was carried out to assess the effect of aging on the performance of mobility tasks. DTC was calculated as ([performance in single-task - performance in dual-task] / performance in single task) × 100%. One-way ancova were carried out to compare the DTC among the three age groups. A significant interaction between age groups and task (F 4,172  = 6.716, P performance under dual-task condition compared with young and middle-aged groups. Furthermore, DTC differences in cognitive task were observed in older women compared with younger and middle-aged women (F 2,86  = 7.649, P task. Dual-task conditions might affect mobility performance differently across the lifespan, and could be particularly challenging in older women.

    Background Health care is increasingly provided in general practice. To meet this demand, the English Department of Health recommends that 50% of all medical students should train for general practice after qualification. Currently 19% of medical students express general practice as their first career choice. Undergraduate exposure to general practice positively influences future career choice. Appropriate undergraduate exposure to general practice is therefore highly relevant to workforce planning Aim This study seeks to quantify current exposure of medical students to general practice and compare it with past provision and also with postgraduate provision. Design and setting A cross-sectional questionnaire in the UK. Method A questionnaire regarding provision of undergraduate teaching was sent to the general practice teaching leads in all UK medical schools. Information was gathered on the amount of undergraduate teaching, how this was supported financially, and whether there was an integrated department of general practice. The data were then compared with results from previous studies of teaching provision. The provision of postgraduate teaching in general practice was also examined. Results General practice teaching for medical students increased from teaching in 1968 to 13.0% by 2008; since then, the percentage has plateaued. The total amount of general practice teaching per student has fallen by 2 weeks since 2002. Medical schools providing financial data delivered 14.6% of the clinical curriculum and received 7.1% of clinical teaching funding. The number of departments of general practice has halved since 2002. Provision of postgraduate teaching has tripled since 2000. Conclusion Current levels of undergraduate teaching in general practice are too low to fulfil future workforce requirements and may be falling. Financial support for current teaching is disproportionately low and the mechanism counterproductive. Central intervention may be required to solve

    To describe the experience of Guinean Ebola virus disease (EVD) survivors in Guinea, up to ten months after discharge from the Ebola treatment unit. Cross-sectional study using a standardised semistructured questionnaire among survivors from Conakry and Coyah districts in 2015 in Guinea. We used proportions, mean (standard deviation) and median (interquartile range) to summarise the variables. The McNemar chi-square test was used to compare proportions. The 121 EVD survivors interviewed had a median reintegration time from discharge of 18 weeks (IQR: 14-32 weeks). Most survivors were aged 15-44 years (87.6%) with secondary to higher level of education (68.6%), and 25.6% were healthcare workers. The majority reported a lower socio-economic status (90%), a less favourable work situation (79%) and psychological status (60%). About 31% reported physical health problems. Most survivors reported lower levels of reintegration with friends and at work place (72%) and lower acceptance by others in general (71%) in the period after the EVD as compared to the period before the EVD. Only 55 survivors (45.5%) were involved in one or more activities of the EVD response: participation in clinical studies on the EVD (44 survivors, 36.4%), community sensitisation (28 survivors, 23.1%) or work in Ebola treatment and/or transit centres (23 survivors, 21.7%). There is a need for a long-term follow-up of EVD survivors in Guinea and more efforts to support their social, professional and economic reintegration, especially in rural areas. © 2016 John Wiley & Sons Ltd.

    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

    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.

    The present study, taking a resource-oriented approach to mental health, aimed at investigating mental resilience and its determinants among undergraduate physiotherapy students using quantitative and qualitative tools. A questionnaire-based cross-sectional survey supplemented by 2 focus groups. One university in Hungary. 130 physiotherapy students at years 1, 2, and 3. Sense of coherence, a measure of dynamic self-esteem, as well as social support from family and peers were used to assess mental well-being. A screening instrument for psychological morbidity and perceived stress were used as deficiency-oriented approaches. Student opinions were gathered on positive and negative determinants of mental health. Resilience was lower [mean difference 4.8 (95% CI -3.4; 13.1)], and the occurrence of psychological morbidity (32.5% vs. 0%) was higher among female compared to male students. However, the proportion of students fully supported by their peers was higher among females (63% vs. 37.5%). Female students, unlike their male counterparts, experienced higher stress compared to their peers in the general population. Social support declined as students progressed in their studies though this proved to be the most important protective factor for their mental well-being. Results were fed back to the course organizers recommending the implementation of an evidence-based method to improve social support as delineated by the Guide to Community Preventive Services of the US the outcomes of which are to be seen in the future.

    Individuals with Rett syndrome (RTT) can have variable manifestations of stereotypies. In this nation-wide cross-sectional study, we recruited all individuals with RTT in Taiwan diagnosed as RTT by neurologists based on genetic findings and diagnostic criteria. The data were collected using questionnaire. A total 43 cases of typical RTT and 15 cases of atypical RTT, aged from 2.1 to 40.1 years, were enrolled. They included 3 (5.2%) in stage II, 42 (72.4%) in stage III, and 13 (22.4%) in stage IV. All individuals presented with at least one stereotypy. Individuals with atypical RTT had more varied stereotypies (mean: 14 ± 6) compared to those with typical RTT (mean: 9 ± 5) (P = 0.003). Flapping (73.3%) and wringing (58.1%) were the most common hand stereotypies in atypical and typical RTT, respectively. Compared with typical RTT, hair pulling, bruxism, retropulsion, and protrusion of lips were more common in atypical RTT (P = 0.003, P = 0.006, P = 0.003 and clinical severities, and hand functions. Although there were no age-related changes in stereotypies in atypical RTT, flapping (P = 0.012), clapping (P = 0.044), and mouthing with single hand (P = 0.009) were significantly more prevalent in individuals aged <10 years with typical RTT, and they decreased after 10 years. In conclusion, our study showed that the stereotypical movements varied in typical and atypical RTT, implying the heterogeneous nature of the disease and the pathogenic mechanisms of RTT with atypical features.

    Occupational hearing loss is an increasingly prevalent occupational condition worldwide, and has been reported to occur in a wide range of workplaces; however, its prevalence among workers from municipal solid waste landfills (MSWLs) remains less clear. This study aimed to investigate the occupational hearing loss among Chinese MSWL workers. A cross-sectional study of 247 workers from 4 Chinese MSWLs was conducted. Noise and total volatile organic compounds (TVOCs) levels at worksites were determined. We conducted hearing examinations to determine hearing thresholds. A worker was identified as having hearing loss if the mean threshold at 2000, 3000 and 4000 Hz in either ear was equal to or greater than 25 dB. Prevalence of occupational hearing loss was then evaluated. Using unconditional Logistic regression models, we estimated the odds ratios (ORs) of MSWL work associated with hearing loss. According to the job title for each worker, the study subjects were divided into 3 groups, including group 1 of 63 workers without MSWL occupational hazards exposure (control group), group 2 of 84 workers with a few or short-period MSWL occupational hazards exposure, and group 3 of 100 workers with continuous MSWL occupational hazards exposure. Both noise and TVOCs levels were significantly higher at worksites for group 3. Significantly poorer hearing thresholds at frequencies of 2000, 3000 and 4000 Hz were found in group 3, compared with that in group 1 and group 2. The overall prevalence rate of hearing loss was 23.5%, with the highest in group 3 (36.0%). The OR of MSWL work associated with hearing loss was 3.39 (95% confidence interval [CI]: 1.28-8.96). The results of this study suggest significantly higher prevalence of hearing loss among MSWL workers. Further studies are needed to explore possible exposure-response relationship between MSWL occupational hazards exposure and hearing loss.

    Addressing family planning in the postpartum period is crucial for better maternal, neonatal and child survival because it enables women to achieve healthy interval between births. The contraceptive behavior of women in the postpartum period is usually different from other times in a woman's life cycle due to the additional roles and presence of emotional changes. Therefore, this study is conducted with the aim of assessing the contraceptive behavior of women in the postpartum period. A community-based cross-sectional study was conducted in August 2013 among women who gave birth one year before the study period in Gondar town, Northwest Ethiopia. Multistage cluster sampling technique was employed to recruit a total of 703 study participants. For data collection, a structured and pretested questionnaire was used. Descriptive statistics were done to characterize the study population using different variables. Bivariate and multiple logistic regression models were fitted. Odds ratios with 95% confidence intervals were computed to identify factors associated with contraceptive use. Nearly half (48.4%) of the postpartum women were using different types of contraceptives. The most commonly used method was injectable (68.5%). Resumption of mensus [Adjusted Odds Ratio (AOR) = 8.32 95% Confidence Interval (CI): (5.27, 13.14)], age ≤24 years [AOR = 2.36, 95% CI: (1.19, 4.69), duration of 7-9 months after delivery [AOR = 2.26 95% CI: (1.12, 4.54)], and having antenatal care [AOR = 5.76, 95% CI: (2.18, 15.2)] were the factors positively associated with contraceptive use in the extended postpartum period. Postpartum contraceptive practice was lower as compared to the Ethiopian demographic and health survey 2011 report for urban areas. Strengthening family planning counseling during antenatal care visit and postnatal care would improve contraceptive use in the postpartum period.

    Few studies have focused on investigating hypoalbuminemia in patients during earlier stages of chronic kidney disease (CKD). In particular, little is known about the role of gastrointestinal (GI) symptoms. Our goal in this paper is to study how GI symptoms relate to serum albumin levels in CKD, especially in the context of and compared with inflammation. We performed a cross-sectional study of 3599 patients with chronic kidney disease enrolled in the Chronic Renal Insufficiency Cohort (CRIC) study. All subjects were asked to complete the Modification of Diet in Renal Disease (MDRD) study patient symptom form. Our main predictor is GI symptom score. Serum level of C-reactive protein (CRP) was measured as well. Main outcome measures are serum albumin levels and prevalence of hypoalbuminemia. Of the participants assessed, mean serum albumin was 3.95 ± 0.46 g/dL; 12.7 % had hypoalbuminemia. Patients with lower estimated glomerular filtration rate (eGFR) were likely to have more GI symptoms (apparent at an eGFR Patients with worse GI symptoms had lower dietary protein intake. GI symptoms, like inflammation, were risk factors for lower serum albumin levels. However, adding GI symptom score or CRP into the multivariable regression analysis, did not attenuate the association between lower eGFR and lower albumin or hypoalbuminemia. Increased prevalence of GI symptoms become apparent among CKD patients at relatively high eGFR levels (45 ml/min/1.73 m(2)), long before ESRD. Patients with more severe GI symptoms scores are more likely to have hypoalbuminemia. But our data do not support GI symptoms/decreased protein intake or inflammation as being the main determinants of serum albumin level in CKD patients.

    Full Text Available Context: Dermatoglyphic is the permanent imprint found in hands. Variations of dermatoglyphic patterns among the individuals have been noted. Aims: To find out the dermatoglyphic pattern variations in dental caries between study group and the control group. Settings and Design: A cross-sectional study was done on 300 Bengalee children of Kolkata between the age group of 4-14 years. Materials and Methods: The samples were divided into two groups; study group and control group. Dental caries were detected clinically using mouth mirror and probe in daylight. Ink was applied on palm and finger by pressure pad. Bilateral palm and finger prints were taken by placing the palm and fingers over glazed paper and applying pressure over palm. Finger and palm prints obtained were inspected by magnifying glass for the study of different dermatoglyphic parameters. Statistical analysis used: Analytical statistical method with the help of student′s t-test was used to determine mean values and gender differences in the findings using SPSS version 11.0. Results: The characteristic feature which shows significant increase in caries sample group were increased total finger ridge count (TRFC and absolute finger ridge count (AFRC on fingers, representing pattern size and types. ab count and tr count were significantly lower in male and female caries sample group compared with the control group. Conclusions: There was a significant difference between caries and control group in different patterns and number of "tri radii on fingers" in fingers, the percentage of patterns on all palmar areas, total number of triradii on palm and main line index. Perhaps more systematic larger samples consisting of different genetic population are necessary to verify the conclusion.

    Full Text Available 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.

    Full Text Available Background Celiac disease (CD is a systemic autoimmune disorder due to immune response triggered by ingestion of gluten in the diet. Treatment with lifelong gluten-free diet may impact negatively on the health-related quality of life and may lead to psychological disturbances. The purpose of study was to evaluate quality of life, depression and anxiety in children with celiac disease. Materials and Methods In this cross-sectional study was done between 2013 and 2014 at the Gastroenterology Outpatient Clinic (Ghaem Hospital, Mashhad- Iran, patients with serology and biopsy-proven CD, on a gluten-free diet for at least one year, were included in this study and compared with non-celiac healthy children as controls. We used the questionnaire to investigate quality of life, anxiety and depression. Results There were statistically significant differences between the mean total anxiety (state, trait scores and depression score in the celiac patients and control group. Correlations between state and trait anxiety and depression were statistically significant (P= 0.01, r= 0.35 and (P= 0.001, r= 0.52. Reverse correlations between quality of life of CD children and anxiety (state, trait were statistically significant (P= 0.001, r= 0.51 and P= 0.02, r= 0.32. Mean total score of quality of life was not different in the two groups, but in the physical activity component, quality of life was better in CD patients (P=0.008. Conclusion In current study, anxiety and depression had a significant impact on the course of celiac disease.

    According to the 2010 estimates by the World Health Organization, nearly 285 million (4.24% of total population) people of all ages worldwide are visually impaired. Almost 18.9 million children under 15 years of age are visually impaired globally. In developing countries, 7%-31% of childhood blindness and visual impairment is avoidable. The study was conducted as a cross-sectional study among 1884 school students in Puducherry, in the age group of 10-14 years. A child with presenting maximum vision ≤6/12 Snellen equivalent in the better eye is considered visually impaired. Data were entered in Microsoft Excel 2013 and analyzed using the statistical software SPSS version 21.0. Chi-square test was applied for testing difference in proportion and a P visual impairment (vision ≤6/12) among the study participants was 6.37% (95% confidence interval = 5.27-7.47). The prevalence of visual impairment increased with age and it was found to be high among male students (6.6%) when compared to female students (6%). Presenting vision of 6/6 was observed in 79.8% of the children while with pinhole correction, the proportion increased to 94.6%. The prevalence of visual impairment in our study population was found to be 6.37% and the prevalence was even higher among children who belonged to schools of urban region or private schools. Children with a positive family history of spectacle use were more likely to have visual impairment.

    Objective Taekwondo injuries differ according to the characteristics of the athletes and the competition. This analytical cross-sectional retrospective cohort study aimed to describe reported taekwondo injuries and to determine the prevalence, characteristics and possible risk factors for injuries sustained by athletes of the Spanish national team. In addition, we compared each identified risk factor—age, weight category, annual quarter, injury timing and competition difficulty level—with its relation to injury location and type. Settings Injury occurrences in taekwondo athletes of the Spanish national team during two Olympic periods at the High Performance Centre in Barcelona were analysed. Participants 48 taekwondo athletes (22 male, 26 female; age range 15–31 years) were studied; 1678 injury episodes occurred. Inclusion criteria were: (1) having trained with the national taekwondo group for a minimum of one sports season; (2) being a member of the Spanish national team. Results Independently of sex or Olympic period, the anatomical sites with most injury episodes were knee (21.3%), foot (17.0%), ankle (12.2%), thigh (11.4%) and lower leg (8.8%). Contusions (29.3%) and cartilage (17.6%) and joint (15.7%) injuries were the prevalent types of injury. Chronological age, weight category and annual quarter can be considered risk factors for sustaining injuries in male and female elite taekwondists according to their location and type (p≤0.001). Conclusions This study provides epidemiological information that will help to inform future injury surveillance studies and the development of prevention strategies and recommendations to reduce the number of injuries in taekwondo competition.

    To assess how euthanasia in terminally ill cancer patients affects the grief response of bereaved family and friends. Cross sectional study. Tertiary referral centre for oncology patients in Utrecht, the Netherlands. 189 bereaved family members and close friends of terminally ill cancer patients who died by euthanasia and 316 bereaved family members and close friends of comparable cancer patients who died a natural death between 1992 and 1999. Symptoms of traumatic grief assessed by the inventory of traumatic grief, current feelings of grief assessed by the Texas revised inventory of grief, and post-traumatic stress reactions assessed by the impact of event scale. The bereaved family and friends of cancer patients who died by euthanasia had less traumatic grief symptoms (adjusted difference -5.29 (95% confidence interval -8.44 to -2.15)), less current feeling of grief (adjusted difference 2.93 (0.85 to 5.01)); and less post-traumatic stress reactions (adjusted difference -2.79 (-5.33 to -0.25)) than the family and friends of patients who died of natural causes. These differences were independent of other risk factors. The bereaved family and friends of cancer patients who died by euthanasia coped better with respect to grief symptoms and post-traumatic stress reactions than the bereaved of comparable cancer patients who died a natural death. These results should not be interpreted as a plea for euthanasia, but as a plea for the same level of care and openness in all patients who are terminally ill.

    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.

    Objective To evaluate a cognitive test, the TYM (“test your memory”), in the detection of Alzheimer’s disease. Design Cross sectional study. Setting Outpatient departments in three hospitals, including a memory clinic. Participants 540 control participants aged 18-95 and 139 patients attending a memory clinic with dementia/amnestic mild cognitive impairment. Intervention Cognitive test designed to use minimal operator time and to be suitable for non-specialist use. Main outcome measures Performance of normal controls on the TYM. Performance of patients with Alzheimer’s disease on the TYM compared with age matched controls. Validation of the TYM with two standard tests (the mini-mental state examination (MMSE) and the Addenbrooke’s cognitive examination-revised (ACE-R)). Sensitivity and specificity of the TYM in the detection of Alzheimer’s disease. Results Control participants completed the TYM with an average score of 47/50. Patients with Alzheimer’s disease scored an average of 33/50. The TYM score shows excellent correlation with the two standard tests. A score of ≤42/50 had a sensitivity of 93% and specificity of 86% in the diagnosis of Alzheimer’s disease. The TYM was more sensitive in detection of Alzheimer’s disease than the mini-mental examination, detecting 93% of patients compared with 52% for the mini-mental state exxamination. The negative and positive predictive values of the TYM with the cut off of ≤42 were 99% and 42% with a prevalence of Alzheimer’s disease of 10%. Thirty one patients with non-Alzheimer dementias scored an average of 39/50. Conclusions The TYM can be completed quickly and accurately by normal controls. It is a powerful and valid screening test for the detection of Alzheimer’s disease. PMID:19509424

    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.

    Full Text Available Personality influences decision making and ethical considerations. Its influence on the occurrence of research misbehavior has never been studied. This study aims to determine the association between personality traits and self-reported questionable research practices and research misconduct. We hypothesized that narcissistic, Machiavellianistic and psychopathic traits as well as self-esteem are associated with research misbehavior.Included in this cross-sectional study design were 535 Dutch biomedical scientists (response rate 65% from all hierarchical layers of 4 university medical centers in the Netherlands. We used validated personality questionnaires such as the Dark Triad (narcissism, psychopathy, and Machiavellianism, Rosenberg's Self-Esteem Scale, the Publication Pressure Questionnaire (PPQ, and also demographic and job-specific characteristics to investigate the association of personality traits with a composite research misbehavior severity score.Machiavellianism was positively associated (beta 1.28, CI 1.06-1.53 with self-reported research misbehavior, while narcissism, psychopathy and self-esteem were not. Exploratory analysis revealed that narcissism and research misconduct were more severe among persons in higher academic ranks (i.e., professors (p<0.01 and p<0.001, respectively, and self-esteem scores and publication pressure were lower (p<0.001 and p<0.01, respectively as compared to postgraduate PhD fellows.Machiavellianism may be a risk factor for research misbehaviour. Narcissism and research misbehaviour were more prevalent among biomedical scientists in higher academic positions. These results suggest that personality has an impact on research behavior and should be taken into account in fostering responsible conduct of research.

    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. Therefore, the aim of this study was to assess the quality of websites in Tehran's public hospitals. 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. 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.

    Despite the efforts of the World Anti-Doping Agency and national anti-doping agencies at the international level, a relatively low and steady rate of positive doping tests still persists all over the world. Evidence on adolescents using doping substances exists, and the proportion of adolescents engaging in doping practices is small but significant. In relation to the international research trends on anti-doping, this study aims to evaluate doping knowledge, practices, and attitudes among Korean adult and adolescent elite athletes to provide effective information on anti-doping policies and education programs. This study was a cross-sectional study of 454 Korean elite athletes (249 adults in 23 events and 205 adolescents in 22 events). Data were collected by an interviewer-administered questionnaire containing items regarding doping practices and knowledge, brief definitions of performance-enhancing substances/methods and recreational substances, and the Performance Enhancement Attitude Scale (PEAS). Adolescent (47.3%) and adult (57.0%) athletes received information on banned substances of their respective sports from the Korea Anti-Doping Agency, and 39.0 and 53.4% of adolescents and adults, respectively, had knowledge of banned substances and had permissive attitudes toward doping compared to those who were unaware. Adolescent and adult athletes have inadvertently (1.5 and 3.6%, respectively) or knowingly (1.0 and 2.8%, respectively) taken banned performance-enhancing substances, and 2.4 and 3.2%, respectively, knew someone who had taken banned substances. And the adolescent athletes in motor skill category (PEAS: 40.24 ± 10.91) were more permissive toward doping than those in team category (PEAS: 35.08 ± 10.21). An in-depth anti-doping education for Korean athletes should be more widely implemented, and effective anti-doping policy should meet the athletes' demographic characteristics, personalities, and values.

    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.

    The aim of the study was to determine health-related quality of life (HRQoL) of women with surgically treated vulvar intraepithelial neoplasia (VIN) and vulvar cancer (VC) during the first week after hospital discharge. Further objectives were to investigate differences between women with VIN and VC as well as to examine whether correlations exist between women's symptom experience and HRQoL. This cross-sectional study was conducted in 8 hospitals in Germany and Switzerland. Women with VIN and VC rated HRQoL with the validated German Short-Form 36. Differences between HRQoL in women with VIN and VC were tested with Wilcoxon rank-sum score. The WOMen with vulvAr Neoplasia (WOMAN) - Patient reported Outcome (PRO) self-report instrument was used to measure women's symptom experience. Correlations between symptoms and HRQoL were calculated using Spearman correlation coefficient. Women with VIN and VC (n = 65) reported lower HRQoL in physical aspects (Physical Component Summary [PCS], 34.9) than that in mental aspects (Mental Component Summary, 40.5). Women with VC had lower HRQoL than women with VIN, as manifested by significant differences concerning the dimensions of "physical functioning" and "role-physical." "Difficulties in daily life" as a distressing symptom correlated with MCS and PCS. Wound-related symptoms correlated with PCS and psychosocial symptoms/issues with MCS. Analysis showed that women with vulvar neoplasia reported lower HRQoL in the physical and mental dimensions 1 week after discharge than comparable studies referring to months or years after surgery. Health-related quality of life is influenced by physical impairment because physical symptoms are prevalent 1 week after discharge. Patient education should focus on symptom management in an early postsurgical phase to enhance women's HRQoL.

    2012-01-01

    Background The link between long working hours and health has been extensively studied for decades. Despite global concern regarding metabolic syndrome, however, no studies to date have solely evaluated the relationship between long working hours and that syndrome. We therefore examined the association between long working hours and metabolic syndrome in a cross-sectional study. Methods Between May and October 2009, we collected data from annual health checkups and questionnaires from employees at a manufacturing company in Shizuoka, Japan. Questionnaires were returned by 1,601 workers (response rate: 96.2%; 1,314 men, 287 women). After exclusions, including women because of a lack of overtime work, the analysis was performed for 933 men. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) for metabolic syndrome. Further, we conducted a stratified analysis by age-group (working hours and metabolic syndrome after adjusting for age, occupation, shift work, smoking status, frequency of alcohol consumption, and cohabiting status. Compared with subjects who worked 7–8 h/day, multivariate ORs for metabolic syndrome were 1.66 (95% CI, 0.91–3.01), 1.48 (95% CI, 0.75–2.90), and 2.32 (95% CI, 1.04–5.16) for those working 8–9 h/day, 9–10 h/day, and >10 h/day, respectively. Similar patterns were obtained when we excluded shift workers from the analysis. In age-stratified analysis, the corresponding ORs among workers aged ≥40 years were 2.02 (95% CI, 1.04–3.90), 1.21 (95% CI, 0.53–2.77), and 3.14 (95% CI, 1.24–7.95). In contrast, no clear association was found among workers aged working hours for increased risk of metabolic syndrome among Japanese male workers. PMID:22651100

    Full Text Available CONTEXT AND OBJECTIVES: Burnout syndrome (BS is characterized by three dimensions: emotional exhaustion, depersonalization and reduced personal fulfillment. The objectives of this study were to evaluate a possible association between BS and weekly workload, and to describe the prevalence of BS and the sociodemographic and occupational profile of on-call physicians in Maceió. DESIGN AND SETTING: Cross-sectional study in intensive care units (ICU at public and private hospitals in Maceió. METHODS: A self-administered form was used to evaluate sociodemographic characteristics and BS through the Maslach Burnout Inventory (MBI among 67 on-call physicians at ICUs in Maceió. Pearson's R correlation test was used to compare workload and emotional exhaustion. For other dimensions, Spearman's S test was used (P < 0.05. Other variables were represented by simple frequencies. The 95% confidence interval was calculated for each variable. RESULTS: Among the physicians studied, 55.22% were female and the mean age was 43.9 ± 8.95 years. The mean weekly workload on call was 43.85 ± 24.49 hours. The frequency of high scores in at least one of the three dimensions of MBI was 70.14%. CONCLUSIONS: Despite the high prevalence of BS, especially among physicians who did not practice regular physical activity, our data did not indicate any significant correlation between weekly workload and any of the three dimensions of BS in this sample. The high prevalence of BS draws attention to the importance of investigating other possible causes, in order to prevent and adequately treat it.

    The Japanese Orthopedic Association first proposed the concept of "locomotive syndrome" in 2007. It refers to circumstances in which elderly people need nursing care services or are at high risk of requiring such services within a short time. Recently, the public health burden of providing nursing care for elderly individuals has increased. Therefore, locomotive syndrome, and the means of preventing it, are a major public health focus in Japan. The purpose of this study was to investigate the relationships of lifestyle factors, such as smoking, alcohol consumption, sleep duration, and dental health, with locomotive syndrome. We conducted a cross-sectional study using an internet panel survey. The participants comprised 747 individuals aged 30-90 years. Factors related to demographics (age, sex), general health (number of teeth, presence of periodontal disease), and lifestyle (smoking, alcohol consumption, sleep duration) were assessed. We also used the 25-question Geriatric Locomotive Function Scale to determine whether each participant had locomotive syndrome. Multivariate analysis was conducted using logistic regression to investigate the independent relationships between locomotive syndrome and lifestyle factors after adjusting for sex and age. A greater proportion of women (17.7%) than men (11.2%) had locomotive syndrome (p syndrome compared with those aged syndrome, whereas sleep duration was not. The frequency of alcohol consumption, except for daily drinking, was also associated with locomotive syndrome. Our study indicates that lifestyle factors, such as smoking and number of existing teeth, may partly affect the prevalence of locomotive syndrome. Hence, lifestyle modifications, such as improving oral hygiene and promoting cessation of smoking, are important means to reduce the risk of locomotive syndrome and should be promoted by public health staff.

    Various aspects of fertility knowledge, including the timing of the fertile window, have consistently been found to be poor. Limited evidence also suggests ovulation monitoring to time intercourse could be common. However, there have been no studies that compare these two aspects of fertility and women's fertility/infertility experiences. To examine the frequency of ovulation monitoring and its relationship with fertility knowledge and experience. A cross-sectional study of women aged 25-50 years resident in southern New Zealand was undertaken in 2011. Randomly selected women were asked to complete a fertility questionnaire. Outcome prevalence measures were calculated with 95% confidence intervals (CI) and associations investigated using χ 2 tests and Poisson regression. Ovulation monitoring was common, having ever been undertaken by 31.4% (95% CI: 28.5-34.3%) of the 1034 participants. However, knowledge was poor, particularly regarding the fertile window. More women who had ever monitored ovulation correctly identified the fertile window, although the proportion was still very low (18.4 vs 13.1% in those who had not, P = 0.027). Regression modelling showed ovulation monitoring was independently associated with seeking medical help to conceive, education and fertility experience, but not with knowledge. This study confirms ovulation monitoring was commonly undertaken. However, many women, including those who had monitored their ovulation, had poor fertility knowledge and failed to identify the fertile window. Poor fertility knowledge needs to be addressed, especially among women intending to conceive. © 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    The spirituality of healthcare providers and their clients is becoming a crucial issue in a world increasingly preoccupied with material issues. In light of such, how do nurses enhance their spiritual intelligence against such materialist pressures? After a 60-year separation of Chinese on both sides of the Taiwan Strait and the rancor between their two governments, what are the similarities and the differences in nurse spirituality profiles between these two different societies? With increasing contact between the two, this issue should be examined and explored, as it has the potential to become an essential unspoken element underpinning holistic care quality. The purpose of this study was to compare spiritual intelligence between nurses in two different Chinese societies. A cross-sectional descriptive and inferential study was conducted at five medical centers in China and Taiwan. A total of 524 registered hospital nurses were recruited as participants. We used R. N. Wolman's (2001) self-reported PsychoMatrix Spirituality Inventory to measure participant levels of spiritual intelligence. The PsychoMatrix Spirituality Inventory incorporated seven factors, including divinity, mindfulness, extrasensory perception, community, intellectuality, trauma, and childhood spirituality. Results showed that social systems did have an impact on nurses' spiritual intelligence. Childhood spirituality and religious beliefs and activities greatly affected and effectively predicted nurses' spiritual intelligence. Nurses on either side of the Taiwan Strait all reported a need to deal with their daily lives pragmatically, objectively, and rationally and relied on empirical evidence in work settings. As social and economic contacts increase across the Taiwan Strait, it is imperative that nurses adopt cultural awareness and sensitivity as they provide holistic care to clients. This study opens doors to dialogue about and a better understanding of nurses' spiritual intelligence in Taiwan

    Lifestyle has a key role in having a life with quality. This is much more critical in academic community. Elite students are the scientific capital of each community; therefore, improvement of their life-style is a very crucial issue and is a way of esteeming them. This study was aimed to scrutinize the life-style of elite dental students to provide a guideline for healthy life-style for their own and for other students, as well. This descriptive and cross-sectional study was carried out on 115 Elite dental students, from a list 175 students, based upon their interest. The HPLP-II questionnaire was used which focuses on 6 behavioral fields: Spiritual Growth, Interpersonal Relations, Nutrition, Physical Activity, Health Responsibility, and Stress Management. The results also compared genders and marital status within the study group. The elite dental students were categorized in 3 age groups as 19≥ yrs (Group I), 20-22 yrs (Group II), and 23≤ yrs. (Group III) for comparison. Data were analyzed using SPSS version 19, independent t-test, one-way ANOVA, and Tukey's test. The mean score of the HPLP-II questionnaire was 2.51±0.27 (out of score 4). Spiritual growth (2.85±0.42) and physical activity (2.16±0.58) were the highest and the lowest scores, respectively. Physical activity was the only subscale different between genders ( p = 0.000). Marital status had not effect on life-style of students. Between the age groups, the physical activity was significantly different between group I and II (0.002). Elite dental students' life-style is most prominent in spiritual growth and interpersonal relationships dimensions, but is the weakest in physical activity and health responsibility behavioral attitudes. To improve the talent of all students, interventional workshops/courses aiming at modification and promotion of students' lifestyle is recommendable in the curriculum.

    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)

    Background With the medical reform, the function of community health centres emerged to be more important recently in China. However, the health service capabilities were tremendously different between metropolitan cities and small cities. This study aims to clarify the level of job satisfaction of Chinese community health workers between a metropolitan (Shenyang) and a small city (Benxi) in Liaoning province and explore its associated factors. Methods A cross-sectional survey was conducted from December 2009 to February 2010. A multi-stage sample was used and a total of 2,100 Chinese community health workers from the two cities completed self-administered questionnaire pertaining to job satisfaction indicated by Minnesota Satisfaction Questionnaire (MSQ), demographic characteristic and working situations, stress and job burnout. The effective response rate was 80.7%. Hierarchical regression analysis was performed to explore the related factors. All data analyses for the two cities were performed separately. Results The averages of overall job satisfaction score of Chinese community health workers were 67.17 in Shenyang and 69.95 in Benxi. Intrinsic job satisfaction and extrinsic job satisfaction among Chinese community health workers were significantly different between Shenyang and Benxi (p job satisfactions, respectively. In Benxi, the fourth model explained 48%, 52% of the variance of intrinsic and extrinsic job satisfactions, respectively. Three significant predictors of intrinsic and extrinsic job satisfactions for the two cities were the two dimensions (social support and decision latitude) of stress and cynicism of burnout. Conclusion From this study, the job satisfaction among Chinese community health workers in the two cities enjoyed a moderate level of job satisfactions, which represented they are not fully satisfied with their jobs. Community health workers in Shenyang had lower job satisfaction as compared to those in Benxi. This study strengthened the

    The link between long working hours and health has been extensively studied for decades. Despite global concern regarding metabolic syndrome, however, no studies to date have solely evaluated the relationship between long working hours and that syndrome. We therefore examined the association between long working hours and metabolic syndrome in a cross-sectional study. Between May and October 2009, we collected data from annual health checkups and questionnaires from employees at a manufacturing company in Shizuoka, Japan. Questionnaires were returned by 1,601 workers (response rate: 96.2%; 1,314 men, 287 women). After exclusions, including women because of a lack of overtime work, the analysis was performed for 933 men. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) for metabolic syndrome. Further, we conducted a stratified analysis by age-group (working hours and metabolic syndrome after adjusting for age, occupation, shift work, smoking status, frequency of alcohol consumption, and cohabiting status. Compared with subjects who worked 7-8 h/day, multivariate ORs for metabolic syndrome were 1.66 (95% CI, 0.91-3.01), 1.48 (95% CI, 0.75-2.90), and 2.32 (95% CI, 1.04-5.16) for those working 8-9 h/day, 9-10 h/day, and >10 h/day, respectively. Similar patterns were obtained when we excluded shift workers from the analysis. In age-stratified analysis, the corresponding ORs among workers aged ≥ 40 years were 2.02 (95% CI, 1.04-3.90), 1.21 (95% CI, 0.53-2.77), and 3.14 (95% CI, 1.24-7.95). In contrast, no clear association was found among workers aged working hours for increased risk of metabolic syndrome among Japanese male workers.

    Neck pain is associated with several alterations in neck motion and motor control. Previous studies have investigated single constructs of neck motor control, while few have applied a comprehensive set of tests to investigate cervical motor control. This comparative cross- sectional study aimed to investigate different motor control constructs in neck pain patients and healthy controls. A total of 166 subjects participated in the study, 91 healthy controls (HC) and 75 neck pain patients (NP) with long-lasting moderate to severe neck pain. Neck flexibility, proprioception, head steadiness, trajectory movement control, and postural sway were assessed using a 3D motion tracking system (Liberty). The different constructs of neck motion and motor control were based on tests used in previous studies. Neck flexibility was lower in NP compared to HC, indicated by reduced cervical ROM and conjunct motion. Movement velocity was slower in NP compared to HC. Tests of head steadiness showed a stiffer movement pattern in NP compared to HC, indicated by lower head angular velocity. NP patients departed less from a predictable trajectory movement pattern (figure of eight) compared to healthy controls, but there was no difference for unpredictable movement patterns (the Fly test). No differences were found for postural sway in standing with eyes open and eyes closed. However, NP patients had significantly larger postural sway when standing on a balance pad. Proprioception did not differ between the groups. Largest effect sizes (ES) were found for neck flexibility (ES range: 0.2-0.8) and head steadiness (ES range: 1.3-2.0). Neck flexibility was the only construct that showed a significant association with current neck pain, while peak velocity was the only variable that showed a significant association with kinesiophobia. NP patients showed an overall stiffer and more rigid neck motor control pattern compared to HC, indicated by lower neck flexibility, slower movement velocity

    Heterogeneity exists within the low back pain (LBP) population. Some patients recover after every pain episode, whereas others suffer daily from LBP complaints. Until now, studies rarely make a distinction between recurrent low back pain (RLBP) and chronic low back pain (CLBP), although both are characterized by a different clinical picture. Clinical experiences also indicate that heterogeneity exists within the CLBP population. Muscle degeneration, like atrophy, fat infiltration, alterations in muscle fiber type, and altered muscle activity, compromises proper biomechanics and motion of the spinal units in LBP patients. The amount of alterations in muscle structure and muscle function of the paraspinal muscles might be related to the recurrence or chronicity of LBP. The aim of this experimental study is to evaluate differences in muscle structure (cross-sectional area and lean muscle fat index) and muscle activity of the multifidus (MF) and erector spinae (ES) during trunk extension, in patients with RLBP, non-continuous CLBP, and continuous CLBP. This cross-sectional study took place in the university hospital of Ghent, Belgium. Muscle structure characteristics and muscle activity were assessed by magnetic resonance imaging (MRI). Fifty-five adults with non-specific LBP (24 RLBP in remission, 15 non-continuous CLBP, 16 continuous CLBP) participated in this study. Total cross-sectional area, muscle cross-sectional area, fat cross-sectional area, lean muscle fat index, T2-rest and T2-shift were assessed. A T1-weighted Dixon MRI scan was used to evaluate spinal muscle cross-sectional area and fat infiltration in the lumbar MF and ES. Muscle functional MRI was used to evaluate the muscle activity of the lumbar MF and ES during a lumbar extension exercise. Before and after the exercise, a pain assessment was performed. This study was supported by grants from the Special Research Fund of Ghent University (DEF12/AOP/022) without potential conflict of interest

    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. 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. 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 (Ppregnancy, language, and having a health/nutrition qualification. The model indicated that independent variables explained 33% (adjusted R (2)) of the variance found between respondents' knowledge scores. 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 receive support to achieve optimal and

    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)

    To investigate actual and perceived disease control in Australians with asthma, and identify factors associated with overestimation of asthma control. This was a cross-sectional study of Australian adults with asthma, who were recruited via Facebook to complete an online survey. The survey included basic demographic questions, and validated tools assessing asthma knowledge, medication adherence, medicine beliefs, illness perception and asthma control. Items that measured symptoms and frequency of reliever medication use were compared to respondents' self-rating of their own asthma control. Predictors of overestimation of asthma control were determined using multivariate logistic regression. Of 2971 survey responses, 1950 (65.6%) were complete and eligible for inclusion. Overestimation of control was apparent in 45.9% of respondents. Factors independently associated with overestimation of asthma control included education level (OR = 0.755, 95% CI: 0.612-0.931, P = 0.009), asthma knowledge (OR = 0.942, 95% CI: 0.892-0.994, P = 0.029), total asthma control, (OR = 0.842, 95% CI: 0.818-0.867, P addictive (OR = 1.144, 95% CI: 1.017-1.287, P = 0.025), and increased feelings of control over asthma (OR = 1.261, 95% CI: 1.191-1.335), P < 0.001). Overestimation of asthma control remains a significant issue in Australians with asthma. The study highlights the importance of encouraging patients to express their feelings about asthma control and beliefs about medicines, and to be more forthcoming with their asthma symptoms. This would help to reveal any discrepancies between perceived and actual asthma control.

    Child poverty rates are compared throughout Europe to monitor how countries are caring for their children. Child poverty reduction measures need to consider the importance of safe living environments for all children. In this study we investigate how European country-level economic disparity and housing conditions relate to one another, and whether they differentially correlate with child injury mortality. We used an ecological, cross-sectional study design of 26 European countries of which 20 high-income and 6 upper-middle-income. Compositional characteristics of the home and its surroundings were extracted from the 2006 European Union Income Social Inclusion and Living Conditions Database (n = 203,000). Mortality data of children aged 1-14 years were derived from the World Health Organization Mortality Database. The main outcome measure was age standardized cause-specific injury mortality rates analysed by income inequality and housing and neighbourhood conditions. Nine measures of housing and neighbourhood conditions highly differentiating European households at country level were clustered into three dimensions, labelled respectively housing, neighbourhood and economic household strain. Income inequality significantly and positively correlated with housing strain (r = 0.62, P = 0.001) and household economic strain (r = 0.42, P = 0.009) but not significantly with neighbourhood strain (r = 0.34, P = 0.087). Child injury mortality rates correlated strongly with both country-level income inequality and housing strain, with very small age-specific differences. In the European context housing, neighbourhood and household economic strains worsened with increasing levels of income inequality. Child injury mortality rates are strongly and positively associated with both income inequality and housing strain, suggesting that housing material conditions could play a role in the association between income inequality and child health. © 2013 John Wiley & Sons Ltd.

    Full Text Available OBJECTIVES Complex and diverse factors are related to reproductive health (RH behavior among adolescents according to the social and cultural context of each countries. This study examined the prevalence of active RH and factors related to active RH behavior among Indonesian adolescents. METHODS A cross-sectional study was conducted among 1,040 of students who were selected through a multi-stage random sampling technique. A self-administered questionnaire was developed, including the World Health Organization Illustrative Questionnaire for Interview-Surveys with Young People, pubertal development scale, and sexual activity scale, modified in accordance to the Indonesian context. The data were analyzed using descriptive and comparative statistics, as well as logistic regression analyses. RESULTS The prevalence of active RH behavior were more higher in boys (56.6%; 95% confidence interval [CI], 50.6% to 62.6% than in girls (43.7%; 95% CI, 37.6% to 49.8%. Negative attitudes towards RH were a factor related to active RH behavior in both boys and girls. Smoking and kind relationship envisioned before marriage (pacaran [courtship] and nikah siri [non-registered marriage] were factors related to active RH behavior in boys; whereas the absence of access to information on substance abuse was an additional factor in girls. Moreover, an interaction was found between access to information on development and smoking (boys and attitudes on RH (girls as independent variables associated with active RH behavior. CONCLUSIONS Sex education for adolescents in Indonesia, particularly in the context of a health promotion program, should be developed based on prevalent social, cultural, and religious values to prevent active RH behavior. Such programs should focus on the kind of relationship envisioned before marriage and smoking for boys and access to information on subtance abuse for girls.

    Full Text Available Little research has been done into cosmetic outcomes in non-Western breast cancer populations. We aimed to study the prevalence and determinants of dissatisfaction with cosmetic outcome after breast cancer surgery of Asian breast cancer survivors, and its association with patient-reported anxiety, depression, and quality of life. In a hospital-based cross-sectional study, 384 breast cancer survivors of at least 12 months after diagnosis completed questionnaires on satisfaction with cosmetic appearance, quality of life (EORTC-QLQ-C30 and anxiety and depression (HADS. Cumulative logit models were used to examine the adjusted association between dissatisfaction with cosmetic appearance and demographic and clinical characteristics. Kruskal-Wallis test was used to test for associations between dissatisfaction with cosmetic appearance and patient-reported outcomes. Overall, 20% of women reported to be (very dissatisfied with cosmetic appearance. Survivors of Chinese ethnicity were more likely dissatisfied with cosmetic appearance compared to Malay survivors (22% and 14% respectively, adjusted OR = 2.4, 95%CI: 1.4-3.9. Women with DCIS (adjusted OR = 2.2, 95%CI: 1.3-3.7 or advanced stage disease (adjusted OR = 2.2, 95%CI: 1.2-3.9 had a higher risk of being dissatisfied with their cosmetic appearance. Women treated with mastectomy were at a higher risk of dissatisfaction with cosmetic appearance (adjusted OR = 1.7, 95%CI: 1.1-2.5. Dissatisfaction with cosmetic appearance was associated with increased depression scores. In this South-East Asian population, one in five breast cancer patients were (very dissatisfied with the cosmetic outcome of treatment. Chinese women, women with larger tumors and women treated with mastectomy were most likely to report dissatisfaction with cosmetic appearance.

    Full Text Available Physicians' ability to make cost-effective decisions has been shown to be affected by their knowledge of health care costs. This study assessed whether Portuguese family physicians are aware of the costs of the most frequently prescribed diagnostic and laboratory tests.A cross-sectional study was conducted in a representative sample of Portuguese family physicians, using computer-assisted telephone interviews for data collection. A Likert scale was used to assess physician's level of agreement with four statements about health care costs. Family physicians were also asked to estimate the costs of diagnostic and laboratory tests. Each physician's cost estimate was compared with the true cost and the absolute error was calculated.One-quarter (24%; 95% confidence interval: 23%-25% of all cost estimates were accurate to within 25% of the true cost, with 55% (95% IC: 53-56 overestimating and 21% (95% IC: 20-22 underestimating the true actual cost. The majority (76% of family physicians thought they did not have or were uncertain as to whether they had adequate knowledge of diagnostic and laboratory test costs, and only 7% reported receiving adequate education. The majority of the family physicians (82% said that they had adequate access to information about the diagnostic and laboratory test costs. Thirty-three percent thought that costs did not influence their decision to order tests, while 27% were uncertain.Portuguese family physicians have limited awareness of diagnostic and laboratory test costs, and our results demonstrate a need for improved education in this area. Further research should focus on identifying whether interventions in cost knowledge actually change ordering behavior, in identifying optimal methods to disseminate cost information, and on improving the cost-effectiveness of care.

The majority of the family physicians (82%) said that they had adequate access to information about the diagnostic and laboratory test costs. Thirty-three percent thought that costs did not influence their decision to order tests, while 27% were uncertain. Conclusions Portuguese family physicians have limited awareness of diagnostic and laboratory test costs, and our results demonstrate a need for improved education in this area. Further research should focus on identifying whether interventions in cost knowledge actually change ordering behavior, in identifying optimal methods to disseminate cost information, and on improving the cost-effectiveness of care.

    Stress or psychological distress is often described as a causative or maintaining factor in psoriasis. Psychological traits may influence the appraisal, interpretation and coping ability regarding stressful situations. Detailed investigations of psychological traits in relation to stress reactivity in psoriasis are rare. The aim of this study was to examine whether patients with psoriasis who report an association between psychological distress and exacerbation, "stress reactors" (SRs), differ psychologically from those with no stress reactivity "non-stress reactors" (NSRs). This cross-sectional study was conducted among 101 consecutively recruited outpatients with plaque psoriasis. A psychosocial interview was performed including questions concerning stress reactivity in relation to onset and exacerbation. Three validated self-rating scales were used: Spielberger State-Trait Anxiety Inventory (STAI, Form-Y), Beck Depression Inventory (BDI-II) and Swedish Universities Scales of Personality (SSP). Independent samples t-tests, Chi-square tests and one-way ANOVA analyses were used for group comparisons when appropriate. A logistic regression model was designed with SR as the dependent variable. Sixty-four patients (63%) reported a subjective association between disease exacerbation and stress (SRs). Patients defined as SRs reported significantly higher mean scores regarding state and trait anxiety, depression, and also five SSP scale personality traits, i.e. somatic trait anxiety, psychic trait anxiety, stress susceptibility, lack of assertiveness and mistrust, compared with NSRs. In multivariate analysis, SSP-stress susceptibility was the strongest explanatory variable for SR, i.e. OR (95% CI)=1.13 (1.02 - 1.24), p=0.018. According to our results, patients who perceive stress as a causal factor in their psoriasis might have a more vulnerable psychological constitution. This finding suggests important opportunities for clinicians to identify patients who may benefit

    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 Childhood lead poisoning has not made the list of national public health priorities in Lebanon. This study aims at identifying the prevalence and risk factors for elevated blood lead concentrations (B-Pb ≥ 100 μg/L among 1–3 year old children. It also examines the need for universal blood lead screening. Methods This is a cross-sectional study of 281 well children, presenting to the pediatric ambulatory services at the American University of Beirut Medical Center in 1997–98. Blood was drawn on participating children for lead analysis and a structured questionnaire was introduced to mothers asking about social, demographic, and residence characteristics, as well as potential risk factors for lead exposure. Children with B-Pb ≥ 100 μg/L were compared to those with B-Pb Results Mean B-Pb was 66.0 μg/L (median 60.0; range 10–160; standard deviation 26.3 with 39 (14% children with B-Pb ≥ 100 μg/L. Logistic regression analysis showed that elevated B-Pb was associated with paternal manual jobs (odds ratio [OR]: 4.74, residence being located in high traffic areas (OR: 4.59, summer season (OR: 4.39, using hot tap water for cooking (OR: 3.96, exposure to kohl (OR: 2.40, and living in older buildings (OR: 2.01. Conclusion Lead screening should be offered to high-risk children. With the recent ban of leaded gasoline in Lebanon, emphasis should shift to other sources of exposure in children.

    Full Text Available ABSTRACT CONTEXT AND OBJECTIVE: Bacterial vaginosis occurs frequently in pregnancy and increases susceptibility to sexually transmitted infections (STI. Considering that adolescents are disproportionally affected by STI, the aim of this study was to evaluate the cervicovaginal levels of interleukin (IL-1 beta, IL-6, IL-8 and bacterial sialidase in pregnant adolescents with bacterial vaginosis. DESIGN AND SETTING: Cross-sectional study at mother and child referral units in Belém, Pará, Brazil. METHODS: Vaginal samples from 168 pregnant adolescents enrolled were tested for trichomoniasis and candidiasis. Their vaginal microbiota was classified according to the Nugent criteria (1991 as normal, intermediate or bacterial vaginosis. Cervical infection due to Chlamydia trachomatisand Neisseria gonorrhoeae was also assessed. Cytokine and sialidase levels were measured, respectively, using enzyme-linked immunosorbent assays and MUAN conversion in cervicovaginal lavages. Forty-eight adolescents (28.6% were excluded because they tested positive for some of the infections investigated. The remaining 120 adolescents were grouped according to vaginal flora type: normal (n = 68 or bacterial vaginosis (n = 52. Their cytokine and sialidase levels were compared between the groups using the Mann-Whitney test (P < 0.05. RESULTS: The pregnant adolescents with bacterial vaginosis had higher levels of IL-1 beta, IL-6 and IL-8 (P < 0.05. Sialidase was solely detected in 35 adolescents (67.2% with bacterial vaginosis. CONCLUSIONS: Not only IL-1 beta and sialidase levels, but also IL-6 and IL-8 levels are higher in pregnant adolescents with bacterial vaginosis, thus indicating that this condition elicits a more pronounced inflammatory response in this population, which potentially increases vulnerability to STI acquisition.

    Full Text Available CONTEXT AND OBJECTIVE: Oral narrative is a means of language development assessment. However, standardized data for deaf patients are scarce. The aim here was to compare the use of narrative competence between hearing-impaired and normal-hearing children. DESIGN AND SETTING: Analytical cross-sectional study at the Department of Speech-Language and Hearing Sciences, Universidade Federal de São Paulo. METHODS: Twenty-one moderately to profoundly bilaterally hearing-impaired children (cases and 21 normal-hearing children without language abnormalities (controls, matched according to sex, age, schooling level and school type, were studied. A board showing pictures in a temporally logical sequence was presented to each child, to elicit a narrative, and the child's performance relating to narrative structure and cohesion was measured. The frequencies of variables, their associations (Mann-Whitney test and their 95% confidence intervals was analyzed. RESULTS: The deaf subjects showed poorer performance regarding narrative structure, use of connectives, cohesion measurements and general punctuation (P < 0.05. There were no differences in the number of propositions elaborated or in referent specification between the two groups. The deaf children produced a higher proportion of orientation-related propositions (P = 0.001 and lower proportions of propositions relating to complicating actions (P = 0.015 and character reactions (P = 0.005. CONCLUSION: Hearing-impaired children have abnormalities in different aspects of language, involving form, content and use, in relation to their normal-hearing peers. Narrative competence was also associated with the children's ages and the school type.

    Addiction to smartphone usage is a common worldwide problem among adults, which might negatively affect their wellbeing. This study investigated the prevalence and factors associated with smartphone addiction and depression among a Middle Eastern population. This cross-sectional study was conducted in 2017 using a web-based questionnaire distributed via social media. Responses to the Smartphone Addiction Scale - Short version (10-items) were rated on a 6-point Likert scale, and their percentage mean score (PMS) was commuted. Responses to Beck's Depression Inventory (20-items) were summated (range 0-60); their mean score (MS) was commuted and categorized. Higher scores indicated higher levels of addiction and depression. Factors associated with these outcomes were identified using descriptive and regression analyses. Statistical significance was set at P addiction was 50.2 ± 20.3, and MS of depression was 13.6 ± 10.0. A significant positive linear relationship was present between smart phone addiction and depression (y = 39.2 + 0.8×; P smartphone addiction scores were associated with younger age users, (β = - 0.203, adj. P = 0.004). Factors associated with higher depression scores were school educated users (β = - 2.03, adj. P = 0.01) compared to the university educated group and users with higher smart phone addiction scores (β =0.194, adj. P smartphone addiction and depression is alarming. Reasonable usage of smart phones is advised, especially among younger adults and less educated users who could be at higher risk of depression.

    The study investigated the prevalence and factors predicting low back pain among nurses in Slovenian hospitals. The risk factors for low back pain are physical and psychosocial. Implementation of interventions for reducing low back pain calls for management support, accessible equipment, education, knowledge and risk assessment. Low back pain prevalence and incidence among healthcare workers is very high compared to the general population and is a strong risk factor for long-term sickness absence. A cross-sectional study design was utilized. We used validated instruments: Nordic Musculoskeletal Disorder Questionnaire, Stanford Presenteeism Scale and Perceived Stress Scale. The sample included 1744 nursing employees from 16 Slovenian hospitals, ranging from practical nurses, registered nurses, nurses with a bachelor's degree and those with a master's degree. Results revealed a prevalence of low back pain among 85.9% of respondents. Relevant risk factors included female gender, age, length of employment, years in current position, shift work and the number of nurses per shift. In the regression model, factors predicting low back pain included presenteeism with a negative effect on work, presenteeism and maintaining work productivity, inability to control daily life, number of nurses per shift and respondents' age. Future activities should be oriented towards eliminating or reducing risks for low back pain incidents and towards different strategies, guidelines and actions which empower individuals and provide knowledge to manage and prevent low back pain. Slovenian healthcare system planning needs a national strategy to successfully promote LBP preventive and controlling strategies. Management can plan preventive and curative measures to reduce low back pain prevalence among nursing personnel. Management should also implement policies reflecting research findings. © 2017 International Council of Nurses.

    Full Text Available Objectives: Body mass index (BMI, total body fat (TBF, and physical activity in relation to obesity and overweight prevalence among Omani students were studied. Methods: A cross-sectional study of 202 Omani students (101 males and 101 females from Sultan Qaboos University (SQU was carried out. Data were collected by interview using a structured questionnaire. Weight, TBF and physical activity score (PAS were measured using TANITA scales, and height measured using a standardised measuring tape. Results: Subjects were classified based on BMI as: underweight (2.48%, normal weight (69.31%, overweight (26.73% and obese (1.49%. According to TBF, 32.67% of students had low body fat scores (BFS, 26.73% high BFS and 22.28% very high BFS. Low BFS was insignificantly less likely with the increase in the mean hours of weekly exercising, (odds ratio [OR] = 0.708; 95% confidence interval [CI] = 0.448, 1.119 and the PAS (OR = 0.728; 95% CI= 0.562, 0.944. Among high and very high BFS students, the mean hours of weekly exercising (6.73±1.20 and physical activity scores (7.51±1.67 were higher than those of healthy students. Nutrition knowledge was higher among healthy students compared to low BFS, and high and very high BFS subjects. Higher nutrition knowledge was associated with a non-significant lower risk of low BFS (OR = 0.986; 95% CI = 0.958, 1.015, high and very high BFS (OR = 0.984; 95% CI = 0.961, 1.008. Conclusion: High and very high BFS were prevalent among subjects with sedentary lifestyles. Nutritional and physical activity interventions should be introduced to combat the problem of overweight students.

    Motorcyclists' injuries and fatalities are a major public health concern in many developing countries including Ghana. This study therefore aimed to investigate the prevalence of helmet use among motorcyclists in Wa, Ghana. The method used involved a cross-sectional roadside observation at 12 randomly selected sites within and outside the CBD of Wa. A total of 14,467 motorcyclists made up of 11,360 riders and 3107 pillion riders were observed during the study period. Most observed riders (86.5%) and pillion riders (61.7%) were males. The overall prevalence of helmet use among the observed motorcyclists was 36.9% (95% CI: 36.1-37.7). Helmet use for riders was 45.8% (95% CI: 44.8-46.7) whilst that for pillion riders was 3.7% (95 CI: 3.0-4.4). Based on logistic regression analysis, higher helmet wearing rates were found to be significantly associated with female gender, weekdays, morning periods and at locations within the CBD. Riders at locations outside the CBD were about 7 times less likely to wear a helmet than riders within the CBD (48.9% compared to 42.3%; χ(2)(1)=49.526; plegislation that mandates the use of helmets by both riders and pillion riders on all roads in Ghana, helmet use is generally low in Wa. This suggests that all stakeholders in road safety should jointly intensify education on helmet use and pursue rigorous enforcement on all road types especially at locations outside the CBD to improve helmet use in Wa.

    2012-01-01

    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 water-related diarrhoea was found in all types of water and improper water hygiene behaviours still existed among residents. 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 Background. Infectious diseases remain the leading causes of morbidity and mortality worldwide. Against the background of ever-increasing resistance of bacteria, it is necessary to develop effective measures aimed at the structure optimization of consumption of antimicrobial agents. Therefore, the pharmacoepidemiological data describing either the consumption of antimicrobial agents or the resistance level to them is required. Objective: Our aim was to assess the antimicrobial load in term and preterm newborns during their stay in the maternity wards and/or in the intensive care units (ICU. Methods. A retrospective cross-sectional study has been carried out. The analysis included data of 419 newborns from 5 medical centers. The study has been carried out as part of a multi-purpose program on antibiotic resistance containment being held in St. Petersburg from 2014. Results. The antimicrobial load on the child's body expressed in days of the antimicrobial therapy was 1,838 per 1,000 patient-days in children staying in the ICU for not more than 16 days, and 1,434 per 1,000 patient-days when staying in the ICU for more than 16 days. The average duration of the antimicrobial therapy is 28 days in the ICU and 5 days out the ICU (department for newborns, physiological departments. The most commonly, the children were treated with ampicillin — 384 (92%, gentamicin — 254 (61%, and fluconazole — 150 (36%. The prevalence of off-label prescriptions was 41% (of 1,557 analyzed prescriptions, unlicensed prescriptions — 10%. Congenital infections were the main reasons for prescription of antimicrobial drugs — 225 (62%. Conclusion. The high anti-bacterial load in newborns has been established. The indicator 'days of antimicrobial therapy' in the ICU is 4 times higher than that in the United States. The prevalence of off-label and unlicensed prescriptions is comparable with foreign data.

    Isoflavones comprise a class of phytoestrogens that resemble human estrogen in chemical structure, and have weak estrogenic effects. Because estrogen modulates sleep duration and quality, we hypothesized that isoflavones would have a beneficial effect on sleep status in a way similar to estrogen. We conducted a cross-sectional study to investigate the relationship between daily isoflavone intake and sleep status in Japanese subjects. Our study included 1076 Japanese adults aged 20-78 years. Daily isoflavone intake was assessed using a brief self-administered diet history questionnaire, and sleep was evaluated using a self-reported questionnaire. The prevalence of regular sleep duration (7-8 h/day) and sufficient sleep quality were 13.3% and 56.2%, respectively. After adjusting for potential confounding factors, the odds ratios (95% CIs) for optimal sleep duration (7-8 h) when higher isoflavone intakes (Q2-Q4) were compared with low isoflavone intake (Q1) were Q2: 0.94 (0.53-1.56); Q3: 1.28 (0.73-2.24); and Q4: 1.84 (1.06-3.18) (p for trend = 0.013). In the final adjusted model, sufficient sleep quality across categories of isoflavone intake was Q1: 1.00 (reference); Q2: 1.30 (0.91-1.84); Q3: 1.48 (1.03-2.12); and Q4: 1.78 (1.22-2.60); (p for trend = 0.002). Higher daily isoflavone intake was positively associated with optimal sleep duration and quality in a Japanese population. This finding suggests that daily isoflavone intake may have a potentially beneficial effect on sleep status.

    To describe nurses' perceptions concerning their professional practice environment in mainland China and identify factors associated with these views. Globally, the environments in which nurses work influence the quality of nursing practice and health care. A cross-sectional descriptive survey using both paper- and online-based delivery modes was used. A convenience sampling method was used. The survey questionnaire was composed of sociodemographic items and the 38-item Chinese version of Professional Practice Environment survey. The content of the paper-based questionnaire was identical to the online survey. Pearson's chi-square test was conducted to compare the demographic characteristics of these two data sets. Descriptive statistics analysis included frequency, percentage, mean and standard deviation. Multiple linear regression analysis using the Backwards method was applied to identify independent predictors of each subscale of the 38-item Chinese version of Professional Practice Environment. A total of 573 questionnaires were analysed. The mean score of each subscale of the 38-item Chinese version of Professional Practice Environment in this study ranged from 2·66-3·05. All subscales except work motivation (3·05, standard deviation: 0·44) scored less than 3·0. Areas rated as most in need of improvement included control over practice, interpersonal interaction, supportive leadership and handling conflict, and staff relationships with physicians and autonomy. This study has identified nurses' perspectives regarding their workplaces in contemporary China. These data have provided an important baseline for developing and implementing culturally appropriate strategies to improve the working environment of Chinese nurses. A supportive and enabling work environment promotes professional development and the safety and quality of health care. Addressing these factors is important in optimising work place environments. © 2015 John Wiley & Sons Ltd.

    By using a cross-sectional geometry, we show the capability to perform single-dot spectroscopy in self-assembled quantum dots using far-field optics. By using this method, we study the quantum-confined Stark effect in self-assembled quantum dots. For single-stack quantum dots (QDs), we find that the spectra are redshifted with an increase in electric field. For vertically coupled double-stack quantum dots, while most of the QDs are redshifted, some QDs show blueshifted spectra, which can be interpreted as an evidence of coupled QD molecules.

    2013-01-01

    This community based cross-sectional study examined the prevalence and factors associated with depression among urban poor in Peninsular Malaysia. The Patient Health Questionnaire (PHQ-9) was used to determine the presence or absence of depression. The prevalence of depression among the urban poor was 12.3%. Factors significantly associated with depression included respondents under 25 years old, male gender, living in the area for less than four years and those who do not exercise regularly. It is important to identify individuals with depression and its associated factors early because depression can severely affect the quality of life.

    2015-01-01

    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

    Full Text Available Metabolic syndrome (MetS is a growing problem in the United Arab Emirates (UAE. Moreover, the prevalence of overweight and obesity is rapidly increasing in the UAE especially among young females. However, few studies have evaluated the prevalence of MetS among young female adults in the UAE. This study determined the prevalence of MetS in Emirati females aged 17-25 years and its relation to overweight and obesity.In total, 555 Emirati female college students were enrolled in a cross-sectional study, conducted during 2013-2014 at United Arab Emirates University in Al Ain, UAE. Anthropometric measurements, blood pressure and biochemical measurements were collected. MetS was defined according to the harmonised International Diabetes Federation criteria.Of the 555 participants enrolled, 23.1% were overweight and 10.4% were classified as obese. The overall prevalence of MetS was 6.8%. MetS prevalence was highest among obese participants (34.5%, as compared with normal-weight (1.7% and overweight (10.1% participants. MetS was significantly associated with overweight (adjusted odds ratio [aOR] = 3.8, 95% confidence interval [CI]; 1.15-12.52 and obesity (aOR = 11.2, 95% CI; 3.1-40.9, as compared with normal-weight. Waist-hip ratio ≥ 0.8 (aOR = 3.04, 95% CI; 1.10-8.44 was significantly associated with MetS, as compared with waist-hip ratio <0.8. The odds of MetS were 22 fold higher in participants with glycated haemoglobin (HbA1c ≥ 6.5% (aOR = 22.5, 95% CI; 6.37-79.42 compared to HbA1c <6.5%. This difference was 9 fold higher when HbA1c between 5.6%-6.4% was compared to HbA1c <5.6% (aOR = 8.9, 95% CI; 3.4-23.5.The prevalence of MetS among obese Emirati female students was significantly higher than overweight and normal weight students. The high prevalence of MetS highlights the importance of regular screening and intervention programmes targeting weight reduction.

    The authors measured the total and fission cross-sections of 239 Pu with the linear accelerator at Saclay as a pulsed source of neutrons. The total cross-section was measured in the range from 4 to 700 eV and the best resolution used was 1.5 ns/m; the fission cross-section was measured between 4 eV and 6 keV, the best resolution having been 6 ns/m. The transmission measurements on five samples were made at the temperature of liquid nitrogen, and comparisons made with supplementary experiments at ambient temperature made it possible to determine the Doppler broadening factor (Δ = η√E). The resonances were identified from 4 to 500 eV in the total cross-section; the average level spacing was of the order of 2.4 eV. It would appear that, in this energy range, nearly all the levels were identified. The resonance parameters were determined by analysis of shape in conjunction with a least-squares programme on an IBM-7094 computer. The existence of a large number of broad resonances corresponding to very large fission widths has been shown to exist. Statistical study of the fission widths actually shows the existence of two families of resonances, one corresponding to a mean Γ f of the order of 45 meV and the other to a mean Γ/f of about 750 meV. The authors were therefore able to postulate a classification of resonances in terms of two spin states, the level population ratio in each family being: (2J 1 +1)/(2J 2 +1) = 1/3; J 1 = 0 corresponds to the broad resonances and J 2 = 1 to the narrow ones. The partial widths for radiative capture fluctuate slightly around a mean value of 40 meV. By using a multilevel programme, the authors were able to investigate the extent to which the existence of large fission widths might give rise to fictitious resonances (quasi-resonances) and perturbations and also to make a statistical study of the resonance parameters.

    Metabolically healthy obese (MHO) individual is known to be defended from the metabolic complications of obesity. Leukoaraiosis, which is commonly detected on brain magnetic resonance imaging (MRI), is now recognized as a risk of stroke, dementia and death. However, the association between MHO and the prevalence of leukoaraiosis is unclear. In this cross-sectional study of 796 participants who received a medical examination program, we investigated the association between MHO and the prevalence of leukoaraiosis. We used common clinical markers for definition of metabolic healthy status: blood pressure, fasting plasma glucose, triglycerides and high-density lipoprotein cholesterol concentrations. Obesity was defined by body mass index ≥25.0 kg/m 2 . We diagnosed leukoaraiosis by fluid-attenuated inversion recovery without hypointensity on T1-weighted images or the presence of a hyperintensity on T2-weighted images. The crude prevalence proportion of leukoaraiosis was 44.5% (case/n = 171/384) in metabolically healthy nonobese (MHNO) individual, 46.3% (44/95) in MHO individual, 62.3% (114/183) in metabolically unhealthy nonobese (MUNO) individual or 56.6% (77/136) in MUO individual. The odds ratios of prevalence of leukoaraiosis were 1.19 (95% CI 0.74-1.90, p = 0.471) for MHO, 1.79 (1.22-2.62, p = 0.003) for MUNO and 1.56 (1.03-2.37, p = 0.037) for MUO individuals after adjusting for sex, age, smoking statues, habit of exercise and alcohol, compared with MHNO individual. We revealed that MHO individuals were not related with the higher risk of leukoaraiosis, whereas MUNO and MUO individuals were.

    Full Text Available CONTEXT AND OBJECTIVE: Brazil is undergoing a period of epidemiological transition associated with demographic and nutritional changes. The prevalence of obesity is also increasing in children and is causing numerous health problems that are becoming public health issues. The aim here was to evaluate the prevalence of overweight among children of two and three years of age. DESIGN AND SETTING: Cross-sectional study in municipal day care centers in Taubaté, state of São Paulo, Brazil. METHODS: Weight and height measurements were made on 447 preschool children forming a probabilistic randomized sample. Their body mass index (BMI was calculated. Their nutritional status was classified using the World Health Organization reference cutoff points (2006. Their mean weight, height and BMI were compared according to their age and sex. RESULTS: The mean values for the final sample (n = 447 were as follows: mean age: 38.6 months (± 3.5 and Z scores for: weight/height (W/H: 0.50 (± 1.22; height/age: -0.03 (± 1.07; weight/age (W/A: 0.51 (± 1.23; and BMI: 0.51(± 1.23. The prevalence of overweight children (BMI > 1 z was 28.86%, while the prevalence of underweight children (BMI < -2 z was 0.89%. There were no differences in mean BMI among the two and three-year age groups (P = 0.66. CONCLUSION: A high prevalence of overweight was observed in the sample of two and three-year-old children, with practically no malnutrition, thus showing that a significant nutritional transition may already be occurring, even in medium-sized cities of developing countries.

    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

    Introduction The issue of street children is one of the global social problems rising in low- and middle-income countries. These children are vulnerable, but because of a lack of sufficient information, it is very difficult for stakeholders to address their plight in Cameroon. Aim To examine the situation and characteristics of street children in three Cameroonian cities. Objectives To describe the demographic, socio-economic and behavioural profiles of street children. To identify challenges of street children and to compare the results from the three cities on account of their different settings, cultural history and challenges. Materials and methods The study was an analytical cross-sectional survey conducted through researcher-administered questionnaires to 399 street children (homeless for at least a month), in three Cameroonian cities from 1 January 2015 to 30 March 2015. Results The majority of the participants were boys, more than 70% were homeless for less than 12 months and poverty was found to be the most common reason for being on the street. Most of the participants earned less than 500CFA francs (USD 0.85), with many of them resorting to begging, drug abuse, sex work and other risky behaviours. Only two of the respondents (0.5%) regarded the public attitude towards them as supportive. Conclusion As children roam the streets in search of shelter, food and other basic needs, their future hangs in the balance. Understanding the plight of street children highlights the need for immediate design and implementation of intervention strategies to prevent children from living in the streets and assist those who have become street children.

    Full Text Available BACKGROUND: Although iron deficiency is considered to be the main cause of anemia in children worldwide, other contributors to childhood anemia remain little studied in developing countries. We estimated the relative contributions of different factors to anemia in a population-based, cross-sectional survey. METHODOLOGY: We obtained venous blood samples from 1111 children aged 6 months to 10 years living in the frontier town of Acrelândia, northwest Brazil, to estimate the prevalence of anemia and iron deficiency by measuring hemoglobin, erythrocyte indices, ferritin, soluble transferrin receptor, and C-reactive protein concentrations. Children were simultaneously screened for vitamin A, vitamin B(12, and folate deficiencies; intestinal parasite infections; glucose-6-phosphate dehydrogenase deficiency; and sickle cell trait carriage. Multiple Poisson regression and adjusted prevalence ratios (aPR were used to describe associations between anemia and the independent variables. PRINCIPAL FINDINGS: The prevalence of anemia, iron deficiency, and iron-deficiency anemia were 13.6%, 45.4%, and 10.3%, respectively. Children whose families were in the highest income quartile, compared with the lowest, had a lower risk of anemia (aPR, 0.60; 95%CI, 0.37-0.98. Child age (2 pregnancies, 2.01; 1.40-2.87 were positively associated with anemia. Other associated correlates were iron deficiency (2.1; 1.4-3.0, vitamin B(12 (1.4; 1.0-2.2, and folate (2.0; 1.3-3.1 deficiencies, and C-reactive protein concentrations (>5 mg/L, 1.5; 1.1-2.2. CONCLUSIONS: Addressing morbidities and multiple nutritional deficiencies in children and mothers and improving the purchasing power of poorer families are potentially important interventions to reduce the burden of anemia.

    Full Text Available Abstract Background Wearable activity trackers offer considerable promise for helping users to adopt healthier lifestyles. This study aimed to explore users’ experience of activity trackers, including usage patterns, sharing of data to social media, perceived behaviour change (physical activity, diet and sleep, and technical issues/barriers to use. Methods A cross-sectional online survey was developed and administered to Australian adults who were current or former activity tracker users. Results were analysed descriptively, with differences between current and former users and wearable brands explored using independent samples t-tests, Mann-Whitney, and chi square tests. Results Participants included 200 current and 37 former activity tracker users (total N = 237 with a mean age of 33.1 years (SD 12.4, range 18–74 years. Fitbit (67.5% and Garmin devices (16.5% were most commonly reported. Participants typically used their trackers for sustained periods (5–7 months and most intended to continue usage. Participants reported they had improved their physical activity (51–81% more commonly than they had their diet (14–40% or sleep (11–24%, and slightly more participants reported to value the real time feedback (89% compared to the long-term monitoring (78%. Most users (70% reported they had experienced functionality issues with their devices, most commonly related to battery life and technical difficulties. Conclusions Results suggest users find activity trackers appealing and useful tools for increasing perceived physical activity levels over a sustained period.

    To generate a global reference for caesarean section (CS) rates at health facilities. Cross-sectional study. Health facilities from 43 countries. Thirty eight thousand three hundred and twenty-four women giving birth from 22 countries for model building and 10,045,875 women giving birth from 43 countries for model testing. We hypothesised that mathematical models could determine the relationship between clinical-obstetric characteristics and CS. These models generated probabilities of CS that could be compared with the observed CS rates. We devised a three-step approach to generate the global benchmark of CS rates at health facilities: creation of a multi-country reference population, building mathematical models, and testing these models. Area under the ROC curves, diagnostic odds ratio, expected CS rate, observed CS rate. According to the different versions of the model, areas under the ROC curves suggested a good discriminatory capacity of C-Model, with summary estimates ranging from 0.832 to 0.844. The C-Model was able to generate expected CS rates adjusted for the case-mix of the obstetric population. We have also prepared an e-calculator to facilitate use of C-Model (www.who.int/reproductivehealth/publications/maternal_perinatal_health/c-model/en/). This article describes the development of a global reference for CS rates. Based on maternal characteristics, this tool was able to generate an individualised expected CS rate for health facilities or groups of health facilities. With C-Model, obstetric teams, health system managers, health facilities, health insurance companies, and governments can produce a customised reference CS rate for assessing use (and overuse) of CS. The C-Model provides a customized benchmark for caesarean section rates in health facilities and systems. © 2015 World Health Organization; licensed by John Wiley & Sons Ltd on behalf of Royal College of Obstetricians and Gynaecologists.

    To examine the associations between demographic characteristics, health behaviors, workplace health culture, and health-related outcomes in Chinese workplaces. A total of 1508 employees from 10 administrative offices and 6 enterprises were recruited for a cross-sectional survey. Self-administered questionnaires mainly addressed demographic characteristics, health behaviors, workplace health culture, and health-related outcomes including self-rated health, mental health, and happiness. The proportion of participants who reported good health-related outcomes was significantly higher in those working in administrative offices than those working in enterprises. The result of the potential factors related to self-rated health (SRH), mental health, and happiness by logistic regression analyses showed that age and income were associated with SRH; type of workplace, age, smoking, and health culture at the workplace level were associated with mental health; and beneficial health effects of direct leadership was positively associated with happiness. Moreover, there were some similar results among 3 multivariate regression models. Firstly, good SRH (Odds Ratio (OR) = 1.744), mental health (OR = 1.891), and happiness (OR = 1.736) were more common among highly physically active participants compared with those physical inactive. Furthermore, passive smoking was negatively correlated with SRH (OR = 0.686), mental health (OR = 0.678), and happiness (OR = 0.616), while health culture at the individual level was positively correlated with SRH (OR = 1.478), mental health (OR = 1.654), and happiness (OR = 2.916). The present study indicated that workplace health culture, health behaviors, and demographic characteristics were associated with health-related outcomes. Furthermore, individual health culture, physical activity, and passive smoking might play a critical role in workplace health promotion.

    Full Text Available ABSTRACT BACKGROUND: Foot problems are believed to reduce quality of life and are increasingly present. Even among young adults of university age, untreated foot problems can lead to postural and mobility problems. Accordingly, our aim here was to determine the relationship between foot health and quality of life and general health among male and female university students. DESIGN AND SETTING: Observational cross-sectional quantitative study conducted at the Podiatric Medicine and Surgery Clinic of the University of Coruña, Ferrol, Spain. METHODS: A sample of 112 participants of median age 22 years came to a health center, where self-reported data were registered, including professional activity, and scores obtained through the Foot Health Status Questionnaire (FHSQ were compared. RESULTS: In Section One of the FHSQ, the university students recorded lower scores of 66.66 in the footwear domain and 60 in the general foot health domain and higher scores of 84.37 in the foot pain domain and 93.75 in the foot function domain. In Section Two, they obtained lower scores of 60 in the overall health domain and 62.50 in the vigor domain and higher scores of 100 in the physical activity and 87.50 in the social capacity domain. Differences between males and females were evaluated using the Wilcoxon rank-sum test, which showing statistical significance (P < 0.05 regarding the dimensions of footwear and general foot health. CONCLUSIONS: These university students’ quality of life relating to foot health was poor. This appears to be associated with the university period, regardless of gender.

    Menstrual disorders and sexual harassment are common among young women and interfere with their life and activities. We aimed to describe the association of sexual harassment and menstrual disorders among female university students. This cross-sectional, observational study examined the association between sexual harassment and menstrual disorders in a sample of 349 university students in Italy. Students answered an anonymous self-administered questionnaire. Descriptive bivariate analyses and logistic regression analyses were performed. Main outcome measures were associations between levels of exposure to sexual harassment (none, levels 1 and 2) and five menstrual disorders (premenstrual symptoms, heavy bleeding, pain, irregular cycles, and amenorrhea). Among the women interviewed (mean age 20.4 ± 1.45 years), 146 (41.8%) had experienced sexual harassment in the previous 12 months: 91 (26.1%) level 1 and 55 (15.7%) level 2. The frequency of premenstrual symptoms was 31.9% ( n=110); heavy bleeding, 35.3% ( n=124); pain, 51.4% ( n=181); irregular cycles, 55.5% ( n=195); and amenorrhea, 6.7% ( n=23). After adjustment for age, place of birth, being in a couple relationship and receiving hormone therapy, the frequency of menstrual disorders, except for amenorrhea, was increased with sexual harassment, with a regular gradient from no harassment to level 2 harassment. Introducing factors of depression, specific gynaecological problems and lifetime sexual violence did not change the results. For instance, the adjusted odds ratios of premenstrual symptoms were 2.10 [1.19-3.68] for women with level 1 harassment and 3.58 [1.83-7.03] for women with level 2 compared with women without harassment exposure. Sexual harassment is related to the prevalence of menstrual disorders. Healthcare providers should encourage dialogue with patients and address the issue of sexual violence or harassment.

    To determine the differences in breastfeeding among women who did and did not experience domestic violence during pregnancy and postpartum in a Swedish context. In addition, to identify possible differences regarding breastfeeding between groups with or without a history of violence. Further, determine the relationship between exclusive breastfeeding and symptoms of depression. History of violence may increase the risk of depression and a decrease in, or cessation of, breastfeeding. The study has a cross-sectional design. Data were collected prospectively from March 2012 - May 2015. A cohort of 731 mothers answered a questionnaire from a larger project (1.5 years postpartum). Breastfeeding was reported by 93.7% of participants. Women exposed to domestic violence during pregnancy and/or postpartum (4.5%) were just as likely to breastfeed as women who had not reported exposure to domestic violence. There were no statistically significant differences between the groups with or without a history of violence regarding exclusive breastfeeding. Women reporting several symptoms of depression breastfed exclusively to a lesser extent compared with women who had a few symptoms of depression. Domestic violence did not influence breastfeeding prevalence or duration. Breastfeeding did not differ in women with or without a history of violence. Symptoms of depression influenced duration of exclusive breastfeeding. Beyond recognizing women who are exposed to violence, it is important to identify and to support pregnant women and new mothers with symptoms of depression as their health and the health of their infants depends on the mothers' mental well-being. © 2017 John Wiley & Sons Ltd.

    Lower risk of COPD has been reported in black and Asian people, raising questions of poorer recognition or reduced susceptibility. We assessed prevalence and severity of COPD in ethnic groups, controlling for smoking. A retrospective cross-sectional study using routinely collected primary care data in London. COPD prevalence, severity (% predicted forced expiratory volume in 1 second [FEV1]), smoking status, and treatment were compared between ethnic groups, adjusting for age, sex, smoking, deprivation, and practice clustering. Among 358,614 patients in 47 general practices, 47.6% were white, 20% black, and 5% Asian. Prevalence of COPD was 1.01% overall, 1.55% in whites, 0.58% in blacks, and 0.78% in Asians. COPD was less likely in blacks (adjusted odds ratio [OR], 0.44; 95% confidence interval [CI] 0.39-0.51) and Asians (0.82; CI, 0.68-0.98) than whites. Black COPD patients were less likely to be current smokers (OR, 0.56; CI, 0.44-0.71) and more likely to be never-smokers (OR, 4.9; CI, 3.4-7.1). Treatment of patients with similar disease severity was similar irrespective of ethnic origin, except that long-acting muscarinic antagonists were prescribed less in black COPD patients (OR, 0.53; CI, 0.42-0.68). Black ethnicity was a predictor of poorer lung function (% predicted FEV1: B coefficient, -7.6; Pwhites to have COPD after adjusting for lower smoking rates in blacks. It seems likely that the differences observed were due either to ethnic differences in the way cigarettes were smoked or to ethnic differences in susceptibility to COPD.

    Narcolepsy is a disabling disease with a delayed diagnosis. At least 3 years before the disorder identification, several comorbidities can be observed in patients with narcolepsy. The early recognition of narcolepsy symptoms may improve long-term prognosis of the patients. Thus, we aimed to investigate the prevalence of the symptoms associated with narcolepsy and its social and psychological association in a sample of Sao Paulo city inhabitants. We performed a cross-sectional evaluation with 1,008 individuals from the Sao Paulo Epidemiologic Sleep Study (EPISONO). Excessive daytime sleepiness (EDS) was assessed by the Epworth Sleepiness Scale. Volunteers were also asked about the occurrence of cataplectic-like, hypnagogic or hypnopompic hallucinations, and sleep paralysis symptoms. The participants underwent a full-night polysomnography and completed questionnaires about psychological, demographic, and quality of life parameters. We observed a prevalence of 39.2% of EDS, 15.0% of cataplectic-like symptom, 9.2% of hypnagogic or hypnopompic hallucinations, and 14.9% of sleep paralysis in Sao Paulo city inhabitants. A frequency of 6.9% was observed when EDS and cataplectic-like symptoms were grouped. The other associations were EDS + hallucinations (4.7%) and EDS + sleep paralysis (7.5%). Symptomatic participants were predominantly women and younger compared with patients without any narcolepsy symptom (n = 451). Narcolepsy symptomatology was also associated with a poor quality of life and symptoms of depression, anxiety, and fatigue. Narcolepsy-related symptoms are associated with poor quality of life and worse psychological parameters. © 2015 American Academy of Sleep Medicine.

    Full Text Available 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.

    Little is known about health activation and self-management behavior in preventing pressure ulcers (PU) in paraplegic patients. Therefore this study aimed to describe the extent of health activation and self-management behavior in paraplegics to prevent PU's and associations between this behavior and patient characteristics. Furthermore, we aimed to find differences in health activation in paraplegics who never had a PU compared to paraplegics with a previous history of PU's or a new-onset PU's. A cross-sectional survey on health activation and self-management behavior was conducted among adult paraplegics recruited from two rehabilitation centers in the Netherlands. The Patient Activation Measure (PAM-score) was used to measure the extent of health activation. Patient statements on their level of self management behavior to prevent PU were evaluated. The mean PAM-score (0-100) was 54 (±8.1; n = 162) indicating a low level of health activation. Two indicators turned out to be statistically significant associated with health activation: level of education (OR = 2.2, p = 0.017) and degree of paraplegia (OR = 2.8, p = 0.036). Evaluation of health activation levels amongst paraplegics with or without a PU- history showed no significant difference. Analysis of patients statements demonstrated a large discrepancy between intended and actual behavior to prevent pressure ulcers. Level of education and level of paraplegia are significantly associated with health activation. A positive PU-history is not associated with future responsible behavior nor for compliant behavior in terms of health management. Copyright © 2016 Tissue Viability Society.

    Full Text Available Abstract Background Association between psychiatric morbidity and substance abuse among adolescent has been reported. However prevalence and pattern of such dysfunctions are unknown in our environment. Aims To determine the prevalence of psychosocial dysfunction and depressive symptoms among adolescents who abuse substance and also note the influence of socio-demographic factors and type of substance on the pattern of dysfuction. Method A cross-sectional study was carried out among 900 adolescents selected from 29 secondary schools in Enugu metropolis. A multi-stage sampling procedure was used to select the students. The student drug use questionnaire was used to screen respondents for substance abuse. Those who were abusing substance and matched controls (non substance abusers were assessed for psychiatric symptoms using the 35-item Paediatric Symptom Checklist (PSC and the Zung Self-rating Depression Scale (SDS. Social classification was done using the parental educational attainment and occupation. Result A total of 290 students were current substance abusers. The substances most commonly abused were alcohol (31.6%, cola nitida (kola nut (20.7% and coffee (15.7%. Using the PSC scale, 70 (24.1% subjects compared to 29 (10.7% of the controls had scores in the morbidity range of ≥ 28 for psychosocial dysfuction. This was statistically significant (χ2 = 17.57 p = 0.001. Fifty-four subjects (18.6% had scores in the morbidity range of ≥ 50 for depressive symptoms using the Zung SDS compared to 21 (7.7% of controls. This was statistically significant (χ2 = 14.43, p = 0.001. Prevalence of dysfunction was not significantly related to age in both subjects and controls (χ2 = 4.62, p = 0.010, χ2 = 4.8, p = 0.10 respectively. Also using both scales, there was no significant relationship between psychosocial dysfunction and gender or social class in both subjects and control. The prevalence of dysfuction using both scales was significantly higher

    To understand the current status of iodine nutrition among the community residents to compare the level of iodine nutrition in different areas and groups of populations in Zhejiang province. Stratified cluster sampling method was adopted and residents from twenty-two communities in Zhejiang province were selected. A cross-sectional survey was conducted, using questionnaires, laboratory tests, on urinary iodine, water iodine and the concentration of the iodine in salt, which had played positive roles in the calculation of the level of iodine nutrition. of the iodine nutrition in this cross-sectional survey were as follows: the median water iodine and salt iodine of Zhejiang were 2.42 µg/L and 28.8 mg/kg, respectively. The coverage of iodized salts was 79.54%, with the ingesting rate of qualified iodized-salt as 76.65% and the median content of urinary iodine in the population of Zhejiang was 161 µg/L. The average iodine content among pregnant women was 138 µg/L, with the percentage of samples less than 100 µg/L as 25.92%, more than 300 µg/L as 15.30%. The proportions of iodine intake through water, salt and other foods were 1.70%, 76.41% and 21.89%, respectively. The status of iodine nutrition in Zhejiang province in general seemed to be appropriate, but the level of iodine nutrition in pregnant women was less than the requirement, which should call for attention.

    There is a need to improve understanding of role stress and how it affects nurses' wellbeing, burnout and health; and hence the quality and safety of patients' care, organizational outcomes and costs. The focus is on shift charge nurses in hospitals who are accountable during a specific shift for the patients' care and staff functioning in accordance with hospital and unit policy. To compare perceptions of stress and its intensity among hospital shift charge nurses amongst three countries: Israel, USA (state of Ohio) and Thailand. A cross-sectional study was performed across three countries, focusing on a convenience sample of 2616 hospital shift charge nurses recruited from 23 general hospitals. A validated shift Charge Nurse Stress Questionnaire was used to assess impacts of four factors: patient & family complaints, lack of resources, responsibility burden and professional conflict. Descriptive statistics were used to describe demographic and professional characteristics of the participants. Chi square and the Fisher Exact Test were performed to test for demographic differences amongst the three samples. Parametric and non-parametric tests were used to compare mean stress levels amongst the study samples. The mean stress level for the total sample was 2.84 (±0.71) on a Likert scale of 1-5, implying moderate stress levels. Significant differences in stress levels were found among countries, with Thai nurses scoring the highest and Israeli nurses the lowest. Similar perceptions of stress intensity were found for all countries, with the factors "responsibility burden" and "lack of resources" considered the most stressful. Israeli and American nurses perceived similar situations as stressful and different from those perceived by Thai nurses. The findings can be partially explained by demographic, professional and cultural differences. Similarities along with differences were found in the nature and levels of stress experienced across the studied countries. A

    Self-reported data are often used in research studies among military populations. The accuracy of self-reported musculoskeletal injury data among elite military personnel was assessed for issues with recall. Cross-sectional study. Applied research laboratory at a military installation. A total of 101 subjects participated (age 28.5±5.6 years). Study participants were active duty military personnel, with no conditions that precluded them from full duty. Self-reported and medical record reviewed injuries that occurred during a 1-year period were matched by anatomic location, injury side (for extremity injuries), and injury year and type. The accuracy of recall was estimated as the per cent of medical record reviewed injuries correctly recalled in the self-report. The effect of injury anatomic location, injury type and severity and time since injury, on recall, was also assessed. Injuries were classified as recent (≤4 years since injury) or old injuries (>4 years since injury). Recall proportions were compared using Fisher's exact tests. A total of 374 injuries were extracted from the subjects' medical records. Recall was generally low (12.0%) and was not different between recent and old injuries (P=0.206). Injury location did not affect recall (P=0.418). Recall was higher for traumatic fractures as compared with less severe non-fracture injuries (P values 0.001 to Recall for non-fracture injuries was higher for recent as compared with old injuries (P=0.033). This effect of time since injury on recall was not observed for fractures (P=0.522). The results of this study highlight the importance of weighing the advantages and disadvantages of self-reported injury data before their use in research studies in military populations and the need for future research to identify modifiable factors that influence recall. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

     To examine the association between the presence of individual principal investigators' financial ties to the manufacturer of the study drug and the trial's outcomes after accounting for source of research funding.  Cross sectional study of randomized controlled trials (RCTs).  Studies published in "core clinical" journals, as identified by Medline, between 1 January 2013 and 31 December 2013.  Random sample of RCTs focused on drug efficacy.  Association between financial ties of principal investigators and study outcome.  A total of 190 papers describing 195 studies met inclusion criteria. Financial ties between principal investigators and the pharmaceutical industry were present in 132 (67.7%) studies. Of 397 principal investigators, 231 (58%) had financial ties and 166 (42%) did not. Of all principal investigators, 156 (39%) reported advisor/consultancy payments, 81 (20%) reported speakers' fees, 81 (20%) reported unspecified financial ties, 52 (13%) reported honorariums, 52 (13%) reported employee relationships, 52 (13%) reported travel fees, 41 (10%) reported stock ownership, and 20 (5%) reported having a patent related to the study drug. The prevalence of financial ties of principal investigators was 76% (103/136) among positive studies and 49% (29/59) among negative studies. In unadjusted analyses, the presence of a financial tie was associated with a positive study outcome (odds ratio 3.23, 95% confidence interval 1.7 to 6.1). In the primary multivariate analysis, a financial tie was significantly associated with positive RCT outcome after adjustment for the study funding source (odds ratio 3.57 (1.7 to 7.7). The secondary analysis controlled for additional RCT characteristics such as study phase, sample size, country of first authors, specialty, trial registration, study design, type of analysis, comparator, and outcome measure. These characteristics did not appreciably affect the relation between financial ties and study outcomes (odds ratio 3.37, 1

    Full Text Available CONTEXT AND OBJECTIVE: Celiac disease is an autoimmune disorder with an average prevalence of 1% in Europe and the United States. Because of strong European ancestry in southern Brazil, this study aimed to evaluate the seroprevalence of celiac disease among autoimmune thyroiditis patients.DESIGN AND SETTING: Cross-sectional study in a public university hospital.METHODS: This cross-sectional prevalence study included autoimmune thyroiditis patients who were tested for anti-endomysial and anti-transglutaminase antibodies between August 2010 and July 2011.RESULTS: Fifty-three patients with autoimmune thyroiditis were included; 92.5% were women, with mean age of 49.0 ± 13.5 years. Five patients (9.3% were serologically positive for celiac disease: three of them (5.6% were reactive for anti-endomysial antibodies and two (3.7% for anti-transglutaminase. None of them exhibited anemia and one presented diarrhea. Endoscopy was performed on two patients: one with normal histology and the other with lymphocytic infiltrate and villous atrophy.CONCLUSION: The prevalence of celiac disease among patients with autoimmune thyroid disease was 9.3%; one patient complained of diarrhea and none presented anemia. Among at-risk populations, like autoimmune thyroiditis patients, the presence of diarrhea or anemia should not be used as a criterion for indicating celiac disease investigation. This must be done for all autoimmune thyroiditis patients because of its high prevalence.

    Full Text Available Clinicopathological studies are important in determining the brain lesions underlying dementia. Although almost 60% of individuals with dementia live in developing countries, few clinicopathological studies focus on these individuals. We investigated the frequency of neurodegenerative and vascular-related neuropathological lesions in 1,092 Brazilian admixed older adults, their correlation with cognitive and neuropsychiatric symptoms, and the accuracy of dementia subtype diagnosis.In this cross-sectional study, we describe clinical and neuropathological variables related to cognitive impairment in 1,092 participants (mean age = 74 y, 49% male, 69% white, and mean education = 4 y. Cognitive function was investigated using the Clinical Dementia Rating (CDR and the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE; neuropsychiatric symptoms were evaluated using the Neuropsychiatric Inventory (NPI. Associations between neuropathological lesions and cognitive impairment were investigated using ordinal logistic regression. We developed a neuropathological comorbidity (NPC score and compared it to CDR, IQCODE, and NPI scores. We also described and compared the frequency of neuropathological diagnosis to clinical diagnosis of dementia subtype. Forty-four percent of the sample met criteria for neuropathological diagnosis. Among these participants, 50% had neuropathological diagnoses of Alzheimer disease (AD, and 35% of vascular dementia (VaD. Neurofibrillary tangles (NFTs, hippocampal sclerosis, lacunar infarcts, hyaline atherosclerosis, siderocalcinosis, and Lewy body disease were independently associated with cognitive impairment. Higher NPC scores were associated with worse scores in the CDR sum of boxes (β = 1.33, 95% CI 1.20-1.46, IQCODE (β = 0.14, 95% CI 0.13-0.16, and NPI (β = 1.74, 95% CI = 1.33-2.16. Compared to neuropathological diagnoses, clinical diagnosis had high sensitivity to AD and high specificity to dementia with

    Full Text Available Dear Editor, Gender equality amongst healthcare professionals is no doubt paramount to allow both equal opportunity and provision of good quality healthcare. The General Medical Council encourages that all colleagues should be treated fairly, but studies have previously demonstrated gender bias against female medical students (1. Whether this might have any impact on the students’ decision-making process and career pathways has yet to be explored. We aimed to evaluate whether doctors gave students gender-specific advice and the extent to which this advice influenced the students. Furthermore, we explored whether students felt their gender affected their career choices. We carried out a cross-sectional national study of British clinical medical students. A standardised questionnaire was completed by 94 students (54.3% female. The response rate was 88.7%. Results showed that 43.6% (n=41 of students received career advice based purely on their gender, and 63.4% (n=26 of these said that this would influence their career choices. Importantly, 82.9% (n=34 of the students who received gender-specific advice were female. Additionally, 41.2% (n=21 of females felt their gender would restrict their career choices compared with only 11.6% (n=5 of males (p=0.00142. 37.3% (n=19 of females thought their gender would unfairly disadvantage their career progression compared to 4.65% (n=2 of males (p=0.00016. Our results highlighted that doctors gave more gender-specific advice to females compared to males, and that this advice significantly impacts students’ decision making process. Furthermore, females disproportionately felt their careers would be disadvantaged and restricted compared with males. This shows an enormous disparity between male and female attitudes towards medical careers. This can have both long and short-term effects on training, career choices a
