    The epidemiology and the aetiology of inflammatory diseases of the vermiform appendix remain poorly understood. The prevalence of appendiceal diverticulosis and diverticulitis in patients undergoing appendectomy for suspected acute appendicitis was investigated. A retrospective study was completed on patients who underwent appendectomy for suspected acute appendicitis. Pathology reports of all patients were screened for diverticula of the vermiform appendix. Patients with either diverticulitis of the vermiform appendix or normal appendicitis were compared. Out of two sets of consecutive patients (n = 1073), nine (0.8%) were identified with diverticulosis of the vermiform appendix. Two of these patients had diverticulitis of the vermiform appendix without appendicitis, three had diverticulitis with consecutive localized appendicitis, and four had proper acute appendicitis with a noninflamed diverticulum of the vermiform appendix. One patient had perforated appendicitis. Two patients had an obstructing neuroendocrine carcinoid which may have caused diverticular formation. Diverticula of the vermiform appendix are rare. If inflamed, they mimic acute appendicitis and are treated by appendectomy. If not inflamed, and diagnosed intraoperatively, incidental appendectomy is recommended.

    This study was done to find out the histomorphometry of lumen of vermiform appendix in Bangladeshi people. Total 100 fresh appendixes were collected for morphometric study of different age and sex during postmortem examination in the autopsy laboratory of Forensic Medicine Department of Mymensingh Medical College. This cross sectional descriptive study was done by convenient sampling technique. For convenience of differentiating the luminal diameter of vermiform appendix in relation to age and sex, findings were classified in four groups. Group A was up to 20 years, Group B 21-35 years, Group C 36-55 years and Group D 56-70 years. In the study the maximum diameter was in group A of female (87.00 μm) and minimum was (4.70 μm) in group B of female. The mean luminal diameter of vermiform appendix was more in female (60.71 μm) than in male (60.11 μm).

    The vermiform appendix in human is considered to be a vestigial organ by most of the authors. Absence of appendix is already reported in Indian population. Whether the human appendix is performing any function is debatable but when present it can create trouble. So if there is no appendix we can escape the ill-effects of the organ. With this hope the study has been done to see whether the appendix is really going to be rudimentary or absent or not. Marerials and Methods: Length, external diameter, number of lymphoid follicles, maximum diameter of the follicle or submucous coat, thickening of the muscle coat and seromucosal thickening of freshly removed appendix from human cadavers were seen. After fixation in 10% formal saline tissues were stained with haematoxylin-eosin stain and photographs were taken. The results had been tabulated and statistically correlated. The parameters like number of lymphoid follicles, length and diameter all are changed as per the age advancement which is strictly indicating some functional activities of the organ which is against the idea of vestigiality of the appendix. Human appendix cannot be called a vestigial organ unless the functional inactivity is proved. Lymphoid changes which occur after birth to provide the gut immunity is needed to be proved by further studies. There might be incidental absence or rudimentary appendix in human body, but that does not indicate that we would not have any appendix in future.

    The study was done to find out the number of lymphoid follicle of vermiform appendix in Bangladeshi people and to increase the knowledge regarding variational anatomy in our population. Total 40 fresh appendixes were collected for histological study of different age and sex during postmortem examination in the autopsy laboratory of Forensic department of Mymensingh Medical College. This cross sectional descriptive study was done by convenient sampling technique. For convenience of differentiating the number of lymphoid follicle of vermiform appendix in relation to age and sex, findings were classified in four groups, up to 20 years, 21 to 35 years, 36 to 55 years and 56 to 70 years. In the present study the number of lymphoid follicle were highest in group A, mean were (5.40+/-1.30) and lowest in group D where mean were (1.05+/-0.35). In male mean were 3.16 and in female mean were 2.86. Diameter of the lymphoid follicle in group A was highest (40.14+/-2.66) and lowest in group D (0.24+/-1.35). Number of germinal centre are highest in group B (2.20 +/- 0.45) and lowest in group D (0.00 +/- 0.00).

    The vermiform appendix is a worm like tube containing a large amount of lymphoid follicles. In our knowledge, there is a little standard data about the vermiform appendix in Iranian population. Therefore, the objective of this study was to investigate the normal appendix size in Iranian cadavers. A cross-sectional study was undertaken between June 2014 and July 2015, in the autopsy laboratory, Legal Medicine Organization, Razavi Khorasan province, Iran. A total of 693 cadavers with the mean age of 40.46±20.99 years were divided into 10 groups. After writing down position of the appendix, the length, diameter and weight of appendix were measured. Statistical analysis was performed using SPSS software. The mean values of the demographic characteristics included: age= 40.46 ± 20.99 years; weight = 63.47 ± 17.84 kg; height = 159.95 ± 28.23 cm. The mean values of the appendix length, diameter, weight and index in the cadavers were 8.52 ± 2.99 cm, 12.17 ± 4.53 mm, 6.43 ± 3.26 grams and 0.013 ± 0.01, respectively. The most common position of appendix was retrocecal in 71.7% of cases. A significant correlations were evident between the value of demographic data and appendix size (Ppopulation.

    The aim of this study was to assess the frequency of appendiceal pathology in women undergoing surgery for mucinous ovarian neoplasm and to evaluate whether appendicectomy is necessary. This single-institution retrospective study reviewed prevalence of appendiceal lesions in all patients operated on at our institution from 2002 to 2013 with the final diagnosis of mucinous tumor of the ovary. Clinicopathological data were analyzed. One hundred twenty-three cases were identified. These included 45 (37%) benign mucinous ovarian neoplasms, 63 (51%) borderline, and 11 (9%) invasive mucinous ovarian tumors. In addition, 4 (3%) cases of metastatic tumors to the ovary were also identified. Appendiceal pathology was found in association with all types of mucinous ovarian tumors (benign, borderline, and malignant). In 24% of cases, appendix was macroscopically abnormal at the time of the surgery, prompting the surgical removal. Regardless of the gross findings, microscopic abnormality in the appendix was seen in 24% of all cases. The prevalence of significant occult microscopic appendiceal pathology, that is, when the appendix was grossly normal, was 6%. Given the prevalence of coexisting appendiceal pathology found in this study and the reported low rates of complications associated with the procedure, an appendicectomy is recommended in the management of all mucinous ovarian neoplasms.

    Full Text Available BACKGROUND Appendix is derived from a Latin word (Pendere meaning at the end. It is a narrow worm-like tubular diverticulum, which arises from the posteromedial wall of caecum about 2 cms below the ileocaecal junction and is suspended by a peritoneal fold known as mesoappendix. The body of appendix is kinked on itself where the free border of mesoappendix ends. Hence, it is coiled like a worm and so is named the ‘Vermiform Appendix’. The appendix is taken up for study in view of its different positions, varying anatomical relations, and the clinical complications when pathologically affected. The relations, measurements, positions, and arterial supply were studied by gross dissection in 61 specimens (Adults – 33 and foetuses – 28 from the population of Krishna and Warangal districts of Andhra Pradesh. MATERIALS AND METHODS The present study was done on 31 adult specimens, out the length of the appendix, the diameter of the appendix at base, length of the caecum, length of ascending colon were measured. The position of the appendix was classified as per Datta’s classification. Mesenteric attachment to the vermiform appendix were noted. Even arterial supply of the appendix was studied. RESULTS Length of the appendix in adults varied from 2.00 to 25.00 cm as described by different authors, the average being 3.00 to 12.50 cm. The length of the caecum in adults were ranging from 5 to 8 cm. In the present study, the length of appendix was 14.4 cm The origin of the appendicular artery was from inferior division of ileocolic artery. A single appendicular artery is observed in all the specimens almost coinciding with studies of Michels et al. In the present study, in adults, the mesoappendix was extending to the tip in 19 specimens and extending to a variable extent in 14 specimens. Regarding the positions, in adults, they were retrocaecal, retrocolic, and subcaecal positions were 21.21% and splenic, promontory, and pelvic positions were 78

    Analytical expressions for the losses in the displacer clearance gap, a.k.a. the appendix gap, have been refined during the last decades. But most real life Stirling engines violate the assumptions behind these expressions and hence the expressions may not be applicable. In this study the gap has...... of the spatial discretisation in the gap showed that a relatively coarse discretisation was adequate for studying the appendix gap losses and showed significant variations in the axial wall temperature gradients along the gap. A parameter study on the size of the displacer clearance gap was performed...... with different algorithms for computing the heat transfer in the gap. The results showed higher losses for small gap sizes but smaller losses for large gap sizes when compared to analytical expressions for the appendix gap losses. The appendix gap losses were found to influence both the heat intake and work...

  11. A study on 'Vermiform Appendix'--a caecal appendage in common laboratory mammals.

    The vermiform appendix, a small structure without any known function in human being has been regarded as a vestigial remnant of a more developed distal caecum in man's herbivorous ancestors. A detailed study of the morphological and histological changes in the appendix and the caecum of different mammals with varying dietary habits revealed a distinctly well-defined vermiform appendix in rabbit only. However, the apical part of caecum among the carnivorous animals like cat and dog showed a clear histological picture with heavy infiltration of lymphoid tissue in the mucous & sub-mucous coats as seen in rabbit or human being. Thus, the vermiform appendix is in no way a vestigial organ but a specialized structure without any definitely known function, probably concerned with the establishment and maintenance of the body defence and immunity of the body.

    Serrated colorectal polyps often show DNA hypermethylation and/or BRAF mutations and have been implicated in the "serrated neoplastic pathway." Although similar lesions occur in the appendix, they have never been systematically investigated. We evaluated a study group of 56 serrated polyps, a control group of 17 mucinous cystadenomas, and 4 adenocarcinomas with adjacent serrated polyps of the appendix to better understand their pathogenesis. The study cases were classified as nondysplastic or dysplastic serrated polyps and evaluated for MLH-1, MSH-2, MGMT, beta-catenin, p53, and Ki-67 expression, BRAF and KRAS mutations, and microsatellite instability. Serrated polyps usually occurred in older adults with no sex predilection. Most (59%) lacked dysplasia, but all showed similar molecular features, regardless of the degree of dysplasia present. Decreased MLH-1 (50%, P<0.001) and/or MGMT (59%, P<0.001) expression and BRAF (29%, P=0.007) mutations were significantly more common in serrated polyps, but BRAF mutations were detected in a minority of the extracted DNA in 15/16 cases. Of the 28 cases with decreased MLH-1 expression, none showed high-frequency microsatellite instability. Loss of MLH-1 (25%) or MGMT (50%) expression and BRAF or KRAS mutations (50%) were inconsistently present in adenocarcinomas and were not identified in combination in any cases. We conclude that molecular features of the "serrated neoplastic pathway" are present with similar frequencies among dysplastic and nondysplastic serrated appendiceal polyps and are not highly prevalent in adjacent carcinomas. These features, including BRAF mutations, may be more closely related to a serrated morphology in appendiceal polyps rather than biologically important changes.

    The anatomy of the vermiform appendix shows variations in its macroscopic dimensions and microscopic features, some of which have potentials of influencing the clinical aspects of the appendix. The aim of this study was to find out some microscopic features of appendix and evaluate the correlation between the microscopic features of the appendix and the age of the subjects and to determine whether these findings should influence the clinical implications of appendix. In this cross-sectional observational study, thirty adult males' (age from 18 to 67 years) postmortem appendices and adnexa from Bangladeshi victims of road traffic accidents were sectioned at the base, midzone and tip stained with H+E stain and examined under microscope. Measurements were taken at the base, at the midzone and at the tip of the appendix, and the mean of the three measurements was considered as the overall value. The overall number of mucosal glands in a section ranged from 42.33 to 130.00 and the number of the germinal centres varied between 2.33 and 10.00. The overall luminal diameter ranged between 1764.58 and 3208.33 µm. The overall luminal diameter in more than 52 % of cases was between 2700.00 and 3299.99 µm with a median value of 2750 µm. The overall number of mucosal glands showed a tendency towards a positive correlation with age. The overall luminal diameter and the overall number of germinal centres showed a tendency towards a negative correlation with the age. However, none of the tendencies of correlation reached statistically any significant level.

    Anonymous screening of lymphoreticular tissues removed during routine surgery has been applied to estimate the UK population prevalence of asymptomatic vCJD prion infection. The retrospective study of Hilton et al (J Pathol 2004; 203: 733-739) found accumulation of abnormal prion protein in three formalin-fixed appendix specimens. This led to an estimated UK prevalence of vCJD infection of ∼1 in 4000, which remains the key evidence supporting current risk reduction measures to reduce iatrogenic transmission of vCJD prions in the UK. Confirmatory testing of these positives has been hampered by the inability to perform immunoblotting of formalin-fixed tissue. Animal transmission studies offer the potential for 'gold standard' confirmatory testing but are limited by both transmission barrier effects and known effects of fixation on scrapie prion titre in experimental models. Here we report the effects of fixation on brain and lymphoreticular human vCJD prions and comparative bioassay of two of the three prevalence study formalin-fixed, paraffin-embedded (FFPE) appendix specimens using transgenic mice expressing human prion protein (PrP). While transgenic mice expressing human PrP 129M readily reported vCJD prion infection after inoculation with frozen vCJD brain or appendix, and also FFPE vCJD brain, no infectivity was detected in FFPE vCJD spleen. No prion transmission was observed from either of the FFPE appendix specimens. The absence of detectable infectivity in fixed, known positive vCJD lymphoreticular tissue precludes interpreting negative transmissions from vCJD prevalence study appendix specimens. In this context, the Hilton et al study should continue to inform risk assessment pending the outcome of larger-scale studies on discarded surgical tissues and autopsy samples.

    Full Text Available Methicillin-resistant Staphylococcus aureus (MRSA is a major nosocomial pathogen worldwide. Malta is one of the countries with the highest MRSA prevalence in Europe, as identified from hospital blood cultures [1]. However, community prevalence of MRSA has never previously been investigated. This study aimed at establishing the prevalence of community MRSA nasal colonization in Maltese individuals and identifying the clonal characteristics of the detected isolates. Nasal swabs were collected from 329 healthy individuals who were also asked to complete a brief questionnaire about risk factors commonly associated with MRSA carriage and infection. The swabs were transported and enriched in a nutrient broth supplemented with NaCl. The presence of MRSA was then determined by culturing on MRSA Select chromogenic agar and then confirming by several assays, including catalase, coagulase and PBP2a agglutination tests. The isolates were assayed for antibiotic susceptibilities and typed by microarray analysis to determine the clonal characteristics of each strain. The prevalence of MRSA nasal colonization in the healthy Maltese population was found to be 8.81% (95% confidence interval [CI], 5.75–11.87%, much higher than that found in other studies carried out in several countries. No statistical association was found between MRSA carriage and demographics or risk factors; however, this was hindered by the small sample size. Almost all the isolates were fusidic-acid resistant. The majority were found to belong to a local endemic clone (CC5 which seems to be replacing the previously prevalent European clone UK-EMRSA-15 in the country. A new clone (CC50-MRSA-V was also characterized. The presence of such a significant community reservoir of MRSA increases the burdens already faced by the local healthcare system to control the MRSA epidemic. Colonization of MRSA in otherwise healthy individuals may represent a risk for endogenous infection and transmission to

    Full Text Available BACKGROUND The relationship of the various positions of appendix to its clinical picture and course in the patient is a subject of controversy. The objective is to study the correlation between anatomical position of appendix and its varied clinical presentation and also to determine the frequency of different positions of appendix in operated cases of acute appendicitis. MATERIALS AND METHODS This study was conducted from Nov 2012 to April 2014 for a period of 16 months in MVJ Medical College and Research Hospital, Hoskote, Bangalore. There were 150 cases in the study, which were histopathologically positive for appendicitis. RESULTS There were total of 150 cases. The commonest position of the appendix is retrocaecal (67.3% followed by pelvic (16%, preileal (7.3%, post-ileal (4.6%, paracaecal (2.6%, subcaecal (1.3% and subhepatic (0.6%. Certain positions like fixed retrocaecal, pelvic and post-ileal presented more often atypically. CONCLUSION There is no increased predisposition for any of the position of the appendix to get inflamed. Complications were more common in cases fixed retrocaecal, post-ileal and pelvic appendix. The patients with the above positions presented more often atypically than typically and with subtle signs and symptoms leading to delayed diagnosis and increased complications.

    The study was done to find out the number of germinal centre in human vermiform appendix of Bangladeshi people to magnify the knowledge regarding the diverse number of germinal centre of human vermiform appendix in our population in the department of Anatomy, Mymensingh Medical College, Bangladesh from July 2006 to June 2007. Total 40 appendices were collected for histological study of different age and sex during postmortem examination in the autopsy laboratory of department of Forensic Medicine, Mymensingh Medical College. This cross sectional study was done by convenient sampling technique. For convenience of differentiating the changes in number of germinal centre of vermiform appendix in relation to age and sex, findings were classified in four groups, Group A up to 20 years, Group B 21-35 years, Group C 36-55 years and Group D 56-70 years. In the present study the number of germinal centre was highest in Group B (52.38%) but in Group D it was nil. Here mean number of germinal centre in male (1.05) were more than in female (0.8).

    The aim of this study was to investigate the prevalence of kinesiographic coincidence between the most cranial position during deglutition of mandible and habitual occlusal position and to evaluate the distribution of clinical diagnosis according to the kinesiographic pattern of deglutition. 201 random patients in waiting list for dental treatment and classified as orthodontic patients, prosthetic patients, TMD patients and control patients, were evaluated. Kinesiographic records were acquired using K7I and positioning a magnetic sensor frame integral with the head and with the sensory field balanced on an artificial magnet adhering to the mucosa covering the roots of the lower mandibular incisors. The kinesiographic occlusal position was compared to the kinesiographic most cranial position of the mandible during swallowing. 99 patients displayed a discrepancy between the most cranial position during swallowing and the occlusal position. 102 patients did not show any discrepancy. In this group the kinesiographic most cranial position during swallowing coincided with the occlusal position. The finding suggests that computerised kinesiography could be useful to study deglutition, detecting in a reliable way the movement pattern. Atypical deglutition seems to be less atypical than previously though in dental patient population and, despite these data confirm its correlation with malocclusion, we noted an inverse correlation with necessity of prosthetic treatment and no higher prevalence in TMD patients.

    Full Text Available Aim of the study was to clarify the prevalence and status of smoking among today’s teenagers according to the survey. Materials and methods. There was carried out the study of the prevalence of smoking among adolescents in the Dnipro (n = 2299 individuals. Results. According to the results of the survey, there were 20.8 % active smokers among adolescents, among them 89.1 % adolescents smoked every day, including 24.9 % boys and 14.6 % girls. On average, adolescents begin smoking regularly at the age of 14.4 ± 0.1 year. The average length of smoking in adolescents was to 3.4 ± 0.1. The average number of cigarettes adolescents smoked per day made up of 9.1 ± 0.3 units. Studying the type of tobacco products 48.6 % of adolescents were found to smoke light cigarettes. The average index of smoker was 109.1 ± 3.3 and was significantly higher in boys (125.5 ± 4.9 than in girls (91.9 ± 4.0 (p < 0.001. Study of the motivation to quit smoking found that only 20.3 % of teenagers are highly motivated to quit, whereas about 31.7 % of adolescents have no motivation to quit smoking. Conclusions. The study showed that the problem of tobacco use remains highly relevant: in the city every fifth teenager smokes. The findings necessitate widespread introduction of antismoking programs among adolescents, which should be directed first to reduce the intensity of smoking and increase motivation to quit smoking, promote healthy lifestyles, as well as thorough clinical examination of adolescent smokers with the aim of identifying risk groups for the development of chronic obstructive pulmonary disease.

In February 2002, 6 VHA medical centers profiled their inpatients' fall risk profile as one aspect of program initiatives targeted at reducing veterans' fall risk and fall-related injuries, participating in a one-day collection of fall risk measurement using the Morse Fall Scale (MFS) for all inpatients (n = 1819), acute and long-term care units. Data results are reported for age, MFS score, and the relationship between age and score, and by type of ward/unit, ie, predominately acute and critical care or long-term care. The results of this prevalence study documented that the veteran inpatient population are at high-risk for anticipated physiological falls. This Veteran Integrated Services Network-wide Deployment of an Evidence-based Program to Prevent Patient Falls study was completed as part of a nationally funded clinical initiative, National Program Initiative 20-006-1.

    Full Text Available Background. Diverticular disease of the appendix (DDA is a rare disease and it has been shown to be associated with locoregional neoplasms. This study was conducted to characterize clinicopathological features and to investigate its association with appendiceal neoplasms. Methods. We searched the records of the Department of Pathology at Farwaniya Hospital for cases of diverticular disease of the appendix between 2003 and 2011. Histological slides and patient charts were reviewed for relevant information. Consecutive cases of acute appendicitis were selected as a control group. Results. We identified 25 cases of DDA, 24 of which occurred in men. Mean age of DDA patients was 35 ± 10.1 years and was significantly greater than that of appendicitis patients (P=0.027. The mean temperature of cases (37.9° was significantly higher (P=0.012 than that of the controls (37.3°. The cases had lower white blood cell (WBC counts compared to controls (13.6 versus 16.7, P=0.04. Pathological diagnosis identified 4 cases of diverticulosis, 5 cases of diverticulitis, 6 cases of diverticulosis with acute appendicitis, and 10 cases of diverticulitis and appendicitis. None of the cases was associated with any type of neoplasm. Conclusions. DDA is a rare disease, and clinicians and radiologists should be aware of it. Male sex and adult age seem to be risk factors associated with DDA. The disease may not have any direct association with any neoplasm.

    2011-09-01

    Full Text Available Objectives: Goals of epidemiological studies are the description of the measures of frequency of diseases, the attempt to clarify possible etiopathogenic mechanisms, and the provision of data to support health policy decisions. To increase the familiarity of rheumatologists toward epidemiology, we describe the methodology used in a prevalence study of musculoskeletal complaints performed in Chiavari, Italy. Methods: A questionnaire, originally developed by the Epidemiology Unit of the Arthitis Research Council in Manchester, UK, to investigate the prevalence of rheumatoid arthritis, was used after translation and validation. 4456 subjects aged 16 years or more listed in four general practices were invited to participate in the study and to fill the ARC questionnaire. The 3294 responders reported a any past occurrence of joint swelling lasting more than four weeks and the distribution of the swollen joints on a mannequin; b any joint pain lasting more than four weeks; c current joint pain or swelling; d morning stiffness; e whether they had been previously told by a doctor they had arthritis. Results: Four steps were necessary to obtain a 74% response, i.e. direct contact, two mailings and a phone interview. The performance of the different questions was good. The prevalence of the most common conditions among patients answering positively to the questions regarding morning stiffness and symmetrical swelling of joints was as follows: osteoarthritis 2.60%, fibromyalgia 1.30%, carpal tunnel syndrome 1.14%, rheumatoid arthritis 0.31%, and psoriatic arthritis 0.10%. Conclusions: Methodological issues regarding the selection of the population and sample to study, the development of a questionnaire, and the problems in obtaining valid informations are discussed.

    The work performed since 1993 on the study of the elemental profile of Buenos Aires atmosphere is presented. Both aerosol direct sampling and biomonitors have been used and the samples have been analyzed mainly by Instrumental Neutron Activation Analysis (INAA). Due to problems with XRF, Anodic Stripping Voltammetry has been chosen for lead determination and Ion Chromatography for soluble anions. For aerosol direct sampling, analytical and sampling methods are described, as well as the sampling campaigns. Experiments have been performed for studying differences between day/night elemental concentrations along the week and a possible seasonal dependence. Some results of mass concentrations and others from INAA are presented. Sampling with the 'Gent sampler' began during August 1994 at an urban residential area of the city. The results of mass concentrations for the first 28 pairs of samples are shown together with some INAA results, as this is the only technique used for the analysis. Lichens and tree bark were the chosen biomonitors. Sampling and analytical methods by INAA are exposed, presenting some of the results that have been obtained. The participation in the aerosol analysis for the Ushuaia Global Atmospheric Watch Station is also commented. (author)

    A growing number of studies have investigated the prevalence of Molar Incisor Hypomineralization (MIH) around the world. The aim of this study was to systematically estimate the pooled prevalence of MIH. A comprehensive literature research was completed in English and Chinese databases. Random effect models were used to calculate the pooled prevalence. To address the heterogeneity, meta-regression, and sensitivity analyzes were conducted. Publication bias was estimated by trim and fill method. Seventy eligible studies were included. The pooled prevalence of MIH was 14.2% globally. In subgroup analysis, South America (18.0%, 95% CI: 13.8-22.2) and Spain (21.1%, 95% CI: 17.7-24.6) had the highest prevalence. There was no significant difference between males (14.3%, 95% CI: 12.0-16.6) and females (14.4%, 95% CI: 12.8-15.9). The prevalence of MIH among children 10 years of age or younger (15.1%, 95% CI: 12.1-18.2) was much higher than the prevalence of MIH among older children (12.1%, 95% CI: 8.0-16.3). Sample size explained 15.7% heterogeneity. MIH has a high incidence globally, especially among children <10 years old. It is, therefore, imperative to develop more appropriate dental healthcare strategies to care for these children and to identify the etiology of MIH to prevent it occurring. © 2017 BSPD, IAPD and John Wiley & Sons A/S.

    To determine prevalence of delirium in critically ill children and explore associated risk factors. Multi-institutional point prevalence study. Twenty-five pediatric critical care units in the United States, the Netherlands, New Zealand, Australia, and Saudi Arabia. All children admitted to the pediatric critical care units on designated study days (n = 994). Children were screened for delirium using the Cornell Assessment of Pediatric Delirium by the bedside nurse. Demographic and treatment-related variables were collected. Primary study outcome measure was prevalence of delirium. In 159 children, a final determination of mental status could not be ascertained. Of the 835 remaining subjects, 25% screened positive for delirium, 13% were classified as comatose, and 62% were delirium-free and coma-free. Delirium prevalence rates varied significantly with reason for ICU admission, with highest delirium rates found in children admitted with an infectious or inflammatory disorder. For children who were in the PICU for 6 or more days, delirium prevalence rate was 38%. In a multivariate model, risk factors independently associated with development of delirium included age less than 2 years, mechanical ventilation, benzodiazepines, narcotics, use of physical restraints, and exposure to vasopressors and antiepileptics. Delirium is a prevalent complication of critical illness in children, with identifiable risk factors. Further multi-institutional, longitudinal studies are required to investigate effect of delirium on long-term outcomes and possible preventive and treatment measures. Universal delirium screening is practical and can be implemented in pediatric critical care units.

    Full Text Available Stroke is a leading cause of morbidity and mortality worldwide and its late burden has mainly been attributable to developing countries. Lebanon is one of these countries where epidemiological studies on stroke burden are scarce but necessary. Thus, the present study was conducted to assess the prevalence of stroke survivors among Lebanese inhabitants. A cross-sectional survey was carried out using randomly selected landline phone numbers on all governorates to retrieve data on stroke survivors and their sociodemographic characteristics. Results were then standardized over the Lebanese and the World Health Organization (WHO world populations. A total of 6963 Lebanese inhabitants were included in the study; among these were 56 stroke survivors. This led to an adjusted stroke prevalence of 0.50% [95% confidence interval (CI = 0.33–0.66%] and a world-standardized prevalence of 0.60% (95% CI = 0.42–0.78%. A significantly higher stroke prevalence was found among older age groups and more socioeconomically privileged areas. Overall, the study showed a relatively higher prevalence of stroke in this sample of Lebanese inhabitants when compared to other developing countries. However, larger community-based studies with a clinical assessment of stroke cases are needed to confirm our findings.

Four subgroups were selected based on the AED treatment in early pregnancy, valproate, carbamazepine, lamotrigine and women not receiving AED treatment. We compared the prevalence of major congenital malformations within children of these four groups and estimated prevalence ratios (PRs using Poisson regression adjusted for maternal age, sex of child, quintiles of Townsend deprivation score and indication for treatment.Results: In total, 240,071 women were included in the study. A total of 229 women were prescribed valproate in pregnancy, 357 were prescribed lamotrigine and 334 were prescribed carbamazepine and 239,151 women were not prescribed AEDs. Fifteen out of 229 (6.6% women prescribed valproate gave birth to a child with a major congenital malformation. The figures for lamotrigine, carbamazepine and women not prescribed AEDs were 2.7%, 3.3% and 2.2%, respectively. The prevalence of major congenital malformation was similar for women prescribed lamotrigine or carbamazepine compared to women with no AED treatment in pregnancy. For women prescribed valproate in polytherapy, the prevalence was fourfold higher. After adjustments, the effect of estimates attenuated, but the prevalence remained two- to

    Domestic violence is a major contributor to physical and mental ill health of the victim, and it is evident to some degree, in every society of the world. 1) To study perception about domestic violence in the study population. 2) To compare prevalence of domestic violence within the three subgroups of the study population (i.e. spouses of psychotic patients, spouses of non-psychiatric patients and hospital staff). A cross-sectional study was conducted among married men and women coming to Dhiraj General Hospital. Interviews were conducted using a semi-structured questionnaire. Inquiry was done about their perception regarding domestic violence, own experience any time in their life, and about the form of violence. Data was entered and analyzed using SPSS. 42.7% of study participants had never heard the words domestic violence. The overall prevalence of any form of violence in the study population as a whole was 32.3%. There was no significant difference found in the proportion of domestic violence among the three groups. The prevalence of physical, emotional, sexual and economic domestic violence was 16.3%, 25.3%, 2% and 11.3% respectively. Younger age group and female sex were significantly associated with the occurrence of domestic violence. Apart from the high prevalence of domestic violence in the present era, it is evident from the study that the participants' perception about domestic violence was low. Efforts should be made to raise public consciousness and reporting of domestic violence and its attendant consequences.

    2017-12-01

    This descriptive scoping aims to understand how the prevalence of cyberbullying has been estimated across studies. A systematic scoping review of cyberbullying empirical studies was conducted by using three bibliographic databases to search for papers published between January 2004 and August 2014. A protocol was defined to identify the relevant papers. Papers selected were included in a data sheet developed by the authors to record specific findings. In total, 159 studies were included in the scoping review. Most of the prevalence studies were conducted in the last 4 years, mainly in North America ( n = 77) and in Europe ( n = 65). High methodological heterogeneity was found among the studies, which may contribute to explain variability in prevalence estimates. Cyberbullying experiences were assessed through several different perspectives: focused only on victims, focused only on perpetrators, or focused on both victims and perpetrators (without differentiating between if they are victims or perpetrators). Most of the studies tend to assess cybervictimization experiences. However, even considering the same perspective, the same country, and the same recall period, a high variability in the estimates was observed. As a main conclusion, the way in which the prevalence of cyberbullying is estimated is influenced by methodological research options.

    Full Text Available INTRODUCTION: Hepatitis B is a global health problem. Among the South East Asian countries India is in intermediate zone of prevalence I.e. 2 to 5 %. 1 In the state of Tripura the prevalence of Hepatitis B among hemodialysis patients is 7.3%2 and among voluntary blood donors it is 1.2%. 3 The present study is aimed to assess the prevalence of HBV infection in Tripura at community level in particular among the different ethnic communities prevailing in this region. METHODS: A cross sectional study at community level has been done. Total 6202 samples have been collected from healthy individual above 10 years of age and a 1:4 sampling of household done. Serological marker of HBs Ag was done by ELISA.RESULTS: Prevalence of HbsAg sero-positivity was 3.6% (95%CI 3.14 - 4.06 at community level of Tripura. A higher prevalence was found in males than females which was 4.5% (95%CI 3.77-5.23 & 2.65% (95%CI 2.08 – 3.22 respectively. The prevalence of Hepatitis B was found higher among tribal community than non-tribal community which was 5.3% (95%CI 4.49 – 6.10 and 1.97%(95%CI 1.49 – 2.45 respectively. Among tribal population highest prevalence was observed among Chakma community (11.41% which was followed by Reang (7.69%, Noatia (6.09%, Jamatia (5.7%, Murasing (5.15%, Tripuri (4.95%, Halam(4.21%, and Lusai (2.7% respectively. The study shows that HBsAgseropositivity increases with age in community level reaching peak between 61 to 80 years age group I.e. 4.8% which is statistically significant. CONCLUSION: Higher prevalence of Hepatitis B among tribal population is of paramount importance from public health point of view and early intervention by Hepatitis B vaccination will reduce the disease burden among Tribal population in Tripura.

    In accordance with the 1st International pediatric sepsis consensus conference, where sepsis was defined as SIRS associated with suspected or proven infection, we have identified the need to assess the prevalence of SIRS and sepsis in children with abnormal temperatures hospitalized in The Children's Clinical University Hospital in Latvia. A descriptive prospective point prevalence study (using two time periods, each 24 h, randomly chosen) was conducted on all children (n = 943) treated in the hospital. All children with abnormal temperatures - fever or hypothermia (n = 92) - were included in the study. Questionnaires evaluating age-specific SIRS criteria were completed. The prevalence of SIRS was detected with 95% CI. Out of a total of 943 patients treated in the hospital, 10% (n = 92) had abnormal temperatures. In all these cases the abnormal temperature was a fever; hypothermia was not established in any patient. Of the children with fever, 72% (n = 66) had SIRS. Of the SIRS patients, 8% (n = 5) developed sepsis, 5% (n = 3) severe sepsis and 2% (n = 1) septic shock. Seventy-six percent (n = 50) of the SIRS patients had fever in combination with respiratory rate >2 SD above normal for age; 50% (n = 33) had fever with abnormal leukocyte count; 15% (n = 10) had fever with tachycardia >2 SD above normal for age. Most of the SIRS patients (39%, n = 25) were aged 2-5 years. Twenty-one percent (n = 14) of the children with SIRS and 50% (n = 2) of those with severe sepsis and septic shock had an underlying disease. In no case was SIRS and sepsis recognized by doctors and the diagnoses were not recorded on the patients' cards. Our results would indicate a high risk for sepsis development in children with SIRS. Early SIRS diagnosis and awareness of risk of developing sepsis could change the medical approach to the patient in everyday clinical practice, eventually leading to early, goal-directed therapy for sepsis.

Methods: Twenty GPs gave the Lupus Screening Questionnaire (LQS to their patients. The LQS has been completed by 32.521 patients resident in Scandicci, Lastra a Signa and Signa area. On the basis of the LQS analysis an SLE diagnosis was suspected in 30 patients. These 30 patients have been investigated by routine exams, antinuclear antibodies and have been refered to rheumatologist to assess the SLE diagnosis and disease activity (ECLAM Score. Results: The overall population aged >18 years was 71.204 ( 42.474 living in Scandicci, 15.368 in Lastra a Signa and 13.362 in Signa. The diagnosis was confirmed in 23 out of the 30 suspected SLE patients. Eleven out of the 23 SLE patients were from Scandicci, 6 from Lastra a Signa and the other 6 from Signa. The overall rate of SLE prevalence is 71/100.000 (1 case/1408 with a confidence interval of 95%, (confidence limits: 49-92. The rate of SLE prevalence in Scandicci is 81/100.000 (confidence limits: 42-121, in Lastra a Signa 62/100.000 (confidence limits: 32-92 and in Signa 65/100.000 (confidence limits: 36-94. Conclusion: This is the first epidemiological study on SLE prevalence in Italy. The rate of SLE prevalence is similar to that of other European studies. LQS is confirmed as an easy and reliable tool to assess SLE diagnosis also in the Italian population too.

    Violence during pregnancy can be associated with health consequences for both the pregnant woman und the unborn child. The available data on prevalence are insufficient in Germany, an underestimation of the problem is probable. Therefore data from other OECD countries are considered. Searching in the databases EMBASE (incl. Medline), CINAHL, PsycINFO and SSCI in English or German language, primary and secondary studies from OECD countries published from 2004 to 2011 were identified. Studies without a valid instrument were excluded. 20 studies using 6 different, partially modified instruments were identified. In OECD countries the prevalence data vary, depending on the instrument applied and the design of the studies. The majority of the studies underestimate the prevalence of violence during pregnancy. Study results from OECD countries are in the analysed range of the reviews. The data collected in Germany are at the bottom of the spectrum. This suggests an underestimation of the problem in Germany. Further research is needed using more valid instruments and better study designs. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Background: Domestic violence is a major contributor to physical and mental ill health of the victim, and it is evident to some degree, in every society of the world. Objectives: 1 To study perception about domestic violence in the study population. 2 To compare prevalence of domestic violence within the three subgroups of the study population (i.e. spouses of psychotic patients, spouses of non-psychiatric patients and hospital staff. Materials and Methods: A cross-sectional study was conducted among married men and women coming to Dhiraj General Hospital. Interviews were conducted using a semi-structured questionnaire. Inquiry was done about their perception regarding domestic violence, own experience any time in their life, and about the form of violence. Data was entered and analyzed using SPSS. Results: 42.7% of study participants had never heard the words domestic violence. The overall prevalence of any form of violence in the study population as a whole was 32.3%. There was no significant difference found in the proportion of domestic violence among the three groups. The prevalence of physical, emotional, sexual and economic domestic violence was 16.3%, 25.3%, 2% and 11.3% respectively. Younger age group and female sex were significantly associated with the occurrence of domestic violence. Conclusion: Apart from the high prevalence of domestic violence in the present era, it is evident from the study that the participants′ perception about domestic violence was low. Efforts should be made to raise public consciousness and reporting of domestic violence and its attendant consequences.

    To obtain minimum point prevalence rates for the skeletal muscle channelopathies and to evaluate the frequency distribution of mutations associated with these disorders. Analysis of demographic, clinical, electrophysiologic, and genetic data of all patients assessed at our national specialist channelopathy service. Only patients living in the United Kingdom with a genetically defined diagnosis of nondystrophic myotonia or periodic paralysis were eligible for the study. Prevalence rates were estimated for England, December 2011. A total of 665 patients fulfilled the inclusion criteria, of which 593 were living in England, giving a minimum point prevalence of 1.12/100,000 (95% confidence interval [CI] 1.03-1.21). Disease-specific prevalence figures were as follows: myotonia congenita 0.52/100,000 (95% CI 0.46-0.59), paramyotonia congenita 0.17/100,000 (95% CI 0.13-0.20), sodium channel myotonias 0.06/100,000 (95% CI 0.04-0.08), hyperkalemic periodic paralysis 0.17/100,000 (95% CI 0.13-0.20), hypokalemic periodic paralysis 0.13/100,000 (95% CI 0.10-0.17), and Andersen-Tawil syndrome (ATS) 0.08/100,000 (95% CI 0.05-0.10). In the whole sample (665 patients), 15 out of 104 different CLCN1 mutations accounted for 60% of all patients with myotonia congenita, 11 out of 22 SCN4A mutations for 86% of paramyotonia congenita/sodium channel myotonia pedigrees, and 3 out of 17 KCNJ2 mutations for 42% of ATS pedigrees. We describe for the first time the overall prevalence of genetically defined skeletal muscle channelopathies in England. Despite the large variety of mutations observed in patients with nondystrophic myotonia and ATS, a limited number accounted for a large proportion of cases.

    Tooth agenesis is a phenomenon that occurs relatively commonly. The incidence of the missing teeth presented in the previous reports varies according to the studied population. The aim of this study was to find the prevalence of tooth agenesis in a population group in Bucharest. The prevalence and distribution of dental agenesis was determined in a sample of 518 patients, 285 females and 233 males, aged 6 to 41 years, who had been treated in the Clinic of Orthodontics and Dentofacial Orthopedics in Bucharest. The tooth agenesis was diagnosed by using the orthodontic records and study casts for each patient. 35 of the patients, 17 males and 18 females, were diagnosed with at least one absent permanent tooth and 47 missing permanent teeth were reported. A prevalence of 6.757% was observed for tooth agenesis. The mandibular second premolar was found to be the most affected tooth, followed by the maxillary lateral incisor, maxillary second premolar, mandibular central incisors, mandibular second molar and mandibular lateral incisor. The incidence of dental agenesis, its pattern and distribution per tooth type are in accordance with the previous published studies.

    This study aimed to determine the prevalence rate of knee osteoarthritis (OA) and the risk factors for OA in hospitalized elderly patients. We conducted this retrospective study in elderly patients (aged 65 years and older) who were hospitalized in the Geriatric Ward of General Hospital of Guangzhou Military Command of the People's Liberation Army between January 2011 and June 2013, including general condition, present history, past history, physical examination, X-ray results, and disease diagnosis. The prevalence, awareness, and treatment rates of knee OA in hospitalized elderly patients were calculated. Risk factors were computed using multiple logistic regression analysis. Of a total of 267 (17.4%) hospitalized elderly patients diagnosed with knee OA, the prevalence rate of OA was 9.95% in males and 37.76% in females. The rate of awareness among those with OA was 51.68%; the rate of treatment was 83.33%; and the rate of control was 77.39%. The medical expenses for both females (1143±315 yuan month-1) and males (1192±357 yuan month-1) in knee OA patients are higher than that of the non-knee OA group (989±274 yuan month-1, 1038±295 yuan month-1). The risk factors for knee OA include gender (OR=2.448), age (OR=1.124), transportation mode (OR= 8.972), exercise (OR=7.374), bowel evacuation position (OR=5.767), family history of knee OA (OR=2.195), and body mass index (OR=2.469). The prevalence of knee OA is unexpectedly high in hospitalized elderly patients, and the rates of awareness and treatment are less than desirable. Prevention and control measures should be taken in patients with concomitant risk factors.

    Helicobacter pylori infection is considered the most common infection worldwide and is associated with many other disorders. The aim of this study is to determine the prevalence of this infection among patients undergoing endoscopy in Northern Jordan. Between November 1998 and September 2000, all patients referred from the Gastro-esophageal Clinic to the Endoscopy Unit at Princess Basma Teaching Hospital, Irbid, Northern Jordan were enrolled in this prospective study. For each patient clinical and epidemiological data was collected and endoscopy was performed. At least 3 antral biopsies were obtained from each patient, and these were examined histologically for the presence of gastritis and stained for Helicobacter pylori using modified Giemsa stain. A total of 197 consecutive patients (113 females) with a mean age of 40.2 years (range 15-91 years) were studied. Abdominal pain was the highest presenting symptom. Gastritis 91% and esophagitis 42% were the most frequent endoscopic findings. Gastritis was documented histologically in 183 (93%) of patients. Helicobacter pylori was found in 161 patients (82%), with all of these having histological gastritis. The 11 patients with gastric ulcer, compared to the 51 out of the 59 (86%) patients with duodenal ulcer, showed Helicobacter pylori in their biopsies. The prevalence of Helicobacter pylori infection in patients subjected to an upper gastrointestinal endoscopy in Jordan is high. This study confirms that Helicobacter pylori is significantly associated with gastritis and peptic ulcer. Further studies are needed to determine the types of Helicobacter pylori strains present in Jordan. (author)

    Tic disorders are neurodevelopmental disorders of childhood associated with psychiatric comorbidity and academic problems. Estimating the prevalence and understanding the epidemiology of tic disorders is more complex than was once thought. Until fairly recently, tic disorders were thought to be rare, but today tics are believed to be the most common movement disorder, with 0.2-46.3% of schoolchildren experiencing tics during their lifetime. Tentative explanations for differing prevalence estimates include the multidimensional nature of tics with a varied and heterogeneous presentation, and the use of different epidemiological methods and study designs. Literature review and analysis of methodological issues pertinent to epidemiological studies of tic disorders. Epidemiological studies of tic disorders were reviewed, and the main elements of epidemiological studies, including sample selection, case ascertainment strategy, definition of tic disorders, and the degree of coverage of the eligible population (i.e., the response rate) were examined. In order to improve the quality of epidemiological studies of tic disorders, a number of recommendations were made, including but not limited to a review of the diagnostic criteria for tic disorders, and inclusion of new tic disorder categories for those with tics of secondary etiology.

    To estimate the prevalence of overweight and obesity in the Spanish population as measured with body mass index (BMI), waist circumference (WC) and waist to height ratio (WHtR) and to determine the associated cardiovascular risk factors. Pooled analysis with individual data from 11 studies conducted in the first decade of the 21st century. Participants aged 35-74 years were asked about the history of cardiovascular diseases, hypertension, diabetes and hypercholesterolemia. Height, weight, WC, blood pressure, glycaemia, total cholesterol, low-density and high-density lipoprotein cholesterol and coronary risk were measured. The prevalence of overweight (BMI 25-29.9 kg/m(2)), general obesity (BMI ≥ 30 kg/m(2)), suboptimal WC (≥ 80 cm and population. We included 28,743 individuals. The prevalence of overweight and suboptimal WC was 51% and 30% in men and 36% and 22% in women, respectively; general obesity was 28% in both sexes and abdominal obesity 36% in men and 55% in women. The prevalence of WHtR ≥0.5 was 89% and 77% in men and women, respectively. All cardiovascular risk factors were significantly associated with abnormal increased values of BMI, WC and WHtR. Hypertension showed the strongest association with overweight [OR = 1.99 (95% confidence interval 1.81-2.21) and OR = 2.10 (1.91-2.31)]; suboptimal WC [OR = 1.78 (1.60-1.97) and OR = 1.45 (1.26-1.66)], with general obesity [OR = 4.50 (4.02-5.04), and OR = 5.20 (4.70-5.75)] and with WHtR ≥0.5 [OR = 2.94 (2.52-3.43), and OR = 3.02 (2.66-3.42)] in men and women respectively, besides abdominal obesity in men only [OR = 3.51 (3.18-3.88)]. Diabetes showed the strongest association with abdominal obesity in women [OR = 3,86 (3,09-4,89). The prevalence of obesity in Spain was high. Overweight, suboptimal WC, general, abdominal obesity and WHtR ≥0.5 was significantly associated with diabetes, hypertension, hypercholesterolemia and coronary risk.

    Dyspnea is a cardinal symptom for cardiorespiratory diseases. No study has assessed worldwide variation in dyspnea prevalence or predictors of dyspnea. We used cross-sectional data from population-based samples in 15 countries of the BOLD study to estimate prevalence of dyspnea in the full sample as well as in an a priori defined low-risk group (few risk factors or dyspnea-associated diseases). Dyspnea was defined by the modified Medical Research Council questions. We used ordered logistic regression analysis to study the association of dyspnea with site, sex, age, education, smoking habits, low/high BMI, self-reported disease, and spirometry results. Of the 9,484 participants, 27% reported any dyspnea. In the low-risk subsample (N=4,329), 16% reported some dyspnea. In multivariate analyses, all covariates were correlated to dyspnea, but only 13% of dyspnea variation was explained. Women reported more dyspnea than men (odds ratio ≈ 2.1). When forced vital capacity (FVC) fell below 60% of predicted, dyspnea was much more likely. There was considerable geographical variation in dyspnea, even when we adjusted for known risk factors and spirometry results. We were only able to explain 13% of dyspnea variation. PMID:24176991

Mucin-secreting cells with cytoplasms often containing argentaffin and argyrophil granules was the predominant histologic pattern. Lack of neuron-specific enolase activity and their positivity for lysozyme and EMA marker indicate an origin from crypt cell and not a neural crest source. After simple appendectomy, the patient was healthy 3 years following surgery.

    Full Text Available White lesions of the oral mucosa are of concern to the dental surgeon in view of the fact that some of these may be potentially malignant. Oral lichen plane: (OLP and oral lichenoid reactions (OLR share similar clinical appearances but need to be carefully distinguished because of their different etiologies and clinical behaviour. This study screened 5.017 population, in a house-to-house field survey, for tobacco use and investigated the prevalence of oral lichenoid reactions in the 98 quid users. Six subjects with clinical/clinical and histopathological criteria compatible with the diagnosis of OLR were identified. All these subjects were users of ′Gutka′, a unique chewable variant of tobacco quid containing areca nut and catechu. Statistical analysis revealed a significant association between quid habit and lesion occurrence (p < 0.005.

    Preeclampsia is associated with increased cardiovascular and renal risk. The aim of this prospective cohort study was to characterize the early postpartum blood pressure (BP) profile after preeclampsia. We enrolled 115 women with preeclampsia and 41 women with a normal pregnancy in a prospective cohort study. At 6 to 12 week postpartum, we assessed the prevalence of different hypertensive phenotypes using 24-hour ambulatory BP monitoring (ABPM), as well as the risk of salt sensitivity and the variability of BP derived from ABPM parameters. Among patients with preeclampsia, 57.4% were still hypertensive at the office. Daytime ABP was significantly higher in the preeclampsia group (118.9±15.0/83.2±10.4 mm Hg) than in controls (104.8±7.9/71.6±5.3 mm Hg; P preeclampsia women remained hypertensive on ABPM in the postpartum, of whom 24.3% were still under antihypertensive treatment; 17.9% displayed a white-coat hypertension and 11.6% had masked hypertension. In controls, 2.8% had white-coat hypertension; none had masked hypertension or needed hypertensive treatment. The prevalence of nondippers was similar 59.8% in the preeclampsia group versus 51.4% in controls. High-risk class of salt sensitivity of BP was increased in preeclampsia women (48.6%) compared with controls (17.1%); P preeclampsia. This finding may help identify women who should be included in a postpartum cardiovascular risk management program. URL: https://www.clinicaltrials.gov.

    Recent research has suggested a possible link between Parkinson's disease (PD) and Fabry disease. To test this relationship, we administered a self-report and family history questionnaire to determine the prevalence of PD in Fabry disease patients and family members with likely pathogenic alpha-galactosidase A (GLA) mutations. A total of 90 Fabry patients (77 from the online survey and 13 from the Icahn School of Medicine at Mount Sinai (ISMMS)) were included in the analysis. Two of the Fabry disease patients who completed the online survey were diagnosed with PD (2/90, 2.2%). Among probands older than 60, 8.3% (2/24) were diagnosed with PD. Using Kaplan Meier survival analysis, the age-specific risk of PD by age 70 was 11.1%. Family history was available on 72 Fabry families from the online study and 9 Fabry families from ISMMS. Among these 81 families, 6 (7.4%) had one first degree relative who fit the criteria for a conservative diagnosis of PD. The results of this study suggest that there may be an increased risk of developing PD in individuals with GLA mutations, but these findings should be interpreted with caution given the limitations of the study design.

    Hemodialized pediatric patients are a risk population for the hepatitis B and C virus infection. The aim of this paper was to study the serum prevalence of HBV and HCV infection in hemodialized children. We study 61 pediatric patients at hemodialisis, 12 on renal transplant, range between 2 and 20 years old (mean: 12.9 years), 23 male and 38 female. The specific anti-HCV IgC were measured by enzyme immunoassay (ELISA Abbott) and confirmed by LIA-TEK (Organon). The anti-HBV were measured by ELISA Abbott and transaminases by cinetic method (ASAT: 29 UI/L and ALT: 33 UI/L). The 19.7% of studied children were HCV (+) and 29.5% were HBV (+), 38.9% of them were HbsAg (+) and 50% anti-HBs (+). The HCV and HBV infection was more elevated in relation to the transfusion number and the hemodilisis time. The elevation of ALT/ASAT activity isn't a right infection index for HCV and HBV in this children.

    We aimed to determine the prevalence of psoriasis (PS) and seborrheic dermatitis (SD) (erythematous-squamous diseases) in our region and reveal the frequently encountered associated factors to aid in planning appropriate healthcare. A community-based study was conducted with 85 sample groups that reflected the population rate and demography of Tokat Province in northern Anatolia. In this community, the prevalence of PS in people older than 20 years of age was 1.2% and the prevalence of SD was 5.2%. SD rates were higher in patients who used tobacco and especially alcohol. SD prevalence was also higher in patients treated for depression and epilepsy. Furthermore, as education levels increased, SD prevalence increased proportionally. In general, PS prevalence in this region was higher than in Asia and Africa but lower than in Europe and the United States. Whereas SD prevalence varies between 2% and 12% throughout the world, the average SD prevalence was 5.2% in this study.

    To evaluate the diagnostic value of the T1 bright appendix sign for the diagnosis of acute appendicitis in pregnant women. This retrospective study included 125 pregnant women with suspected appendicitis who underwent magnetic resonance (MR) imaging. The T1 bright appendix sign was defined as a high intensity signal filling more than half length of the appendix on T1-weighted imaging. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the T1 bright appendix sign for normal appendix identification were calculated in all patients and in those with borderline-sized appendices (6-7 mm). The T1 bright appendix sign was seen in 51% of patients with normal appendices, but only in 4.5% of patients with acute appendicitis. The overall sensitivity, specificity, PPV, and NPV of the T1 bright appendix sign for normal appendix diagnosis were 44.9%, 95.5%, 97.6%, and 30.0%, respectively. All four patients with borderline sized appendix with appendicitis showed negative T1 bright appendix sign. The T1 bright appendix sign is a specific finding for the diagnosis of a normal appendix in pregnant women with suspected acute appendicitis. • Magnetic resonance imaging is increasingly used in emergency settings. • Acute appendicitis is the most common cause of acute abdomen. • Magnetic resonance imaging is widely used in pregnant population. • T1 bright appendix sign can be a specific sign representing normal appendix.

    Appendix G: Hanson Russian River Ponds Floodplain Restoration: Feasibility Study and Conceptual Design |G-1Appendix GPhysical Evaluation of the Restoration AlternativesRichard McDonald and Jonathan Nelson, PhDU.S. Geological Survey Geomorphology and Sediment Transport Laboratory, Golden, ColoradoIntroductionTo assess the relative and overall impacts of the scenarios proposed in Chapters 7 and 9,(Stage I-A–I-D and Stage II-A –II-E), each of the topographic configurations were evaluated over a range of flows. Thisevaluation was carried out using computational flow modeling tools available in the iRIC public-domain river modeling interface (www.i-ric.org, Nelsonet al.in press). Using the iRIC modeling tools described in more detail below, basic hydraulic computations of water-surface elevation, velocity, shear stress, and other hydraulic variables were carried out for the alternatives in the reach surrounding the project area, from the confluence of Dry Creek upstream to the Wohler road bridge downstream, for the full range of observed flows. This methodology allows comparison of the current channel configuration with the proposed alternatives in terms of inundation period and frequency, depth, water velocity, and other hydraulic information. By integrating this kind of information over the reach of interest and the flow record, critical metrics assessing the impacts of various topographic modifications can be compared to those same metrics for the existing condition or other modification scenarios. In addition, because the iRIC tools include predictions of sediment mobility, suspension of fines, and the potential evolution of the land surface in response to flow, these methods provide evaluation of sediment transport, stability of current and proposed surfaces, and evaluation of how these surfaces might evolve into the future. This hydraulic and sediment transport information is critically important for understanding theimpacts of various proposed alternatives on

    Mucocele of the appendix is an infrequent event, representing 0.3%-0.7% of appendiceal pathology and 8% of appendiceal tumors. It is characterized by a located or diffuse distension of the appendix with a mucus-filled lumen. We describe 35 cases of mucocele of the appendix diagnosed at Ramón y Cajal Hospital between January 1985 and January 2006. A total of 21 males and 14 females with a mean age of 52.7 years are described. Most cases manifested as abdominal pain located in right iliac fossa, but 2 cases were incidental findings at CT-scan and 1 at ultrasonography, performed for other reasons. In 4 cases, mucocele coexisted with colorectal cancer and was an incidental finding during laparotomy performed for tumor resection. Ultrasonography and computed tomography (CT) scan helped to achieve a correct diagnosis. Preoperative diagnosis of mucocele was achieved in 29% of the cases; 88% of patients underwent appendectomy, 2 had ileocecal resection, and 2 others underwent right hemicolectomy. Pathology revealed mucous hyperplasia in 34% of the cases, simple mucocele in 29%, cystadenoma in 31%, and cystadenocarcinoma in 2 patients. Two other patients developed adenocarcinoma of the cecum 12 and 33 months after surgery, and one patient developed pseudomyxoma peritonei after 62 months, causing his death. The pathologist is forced to do an exhaustive study, looking for inadvertent perforations that can change the good prognosis of mucocele. We recommend follow-up of all patients with mucoceles, because sometimes they are associated with colorectal neoplasms and recurrence as pseudomyxoma peritonei.

    To review population-based studies of the prevalence and incidence of epilepsy worldwide and use meta-analytic techniques to explore factors that may explain heterogeneity between estimates. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards were followed. We searched MEDLINE and EMBASE for articles published on the prevalence or incidence of epilepsy since 1985. Abstract, full-text review, and data abstraction were conducted in duplicate. Meta-analyses and meta-regressions were used to explore the association between prevalence or incidence, age group, sex, country level income, and study quality. A total of 222 studies were included (197 on prevalence, 48 on incidence). The point prevalence of active epilepsy was 6.38 per 1,000 persons (95% confidence interval [95% CI] 5.57-7.30), while the lifetime prevalence was 7.60 per 1,000 persons (95% CI 6.17-9.38). The annual cumulative incidence of epilepsy was 67.77 per 100,000 persons (95% CI 56.69-81.03) while the incidence rate was 61.44 per 100,000 person-years (95% CI 50.75-74.38). The prevalence of epilepsy did not differ by age group, sex, or study quality. The active annual period prevalence, lifetime prevalence, and incidence rate of epilepsy were higher in low to middle income countries. Epilepsies of unknown etiology and those with generalized seizures had the highest prevalence. This study provides a comprehensive synthesis of the prevalence and incidence of epilepsy from published international studies and offers insight into factors that contribute to heterogeneity between estimates. Significant gaps (e.g., lack of incidence studies, stratification by age groups) were identified. Standardized reporting of future epidemiologic studies of epilepsy is needed. © 2016 American Academy of Neurology.

    2001-01-01

    The aim of this study is to investigate the growing of the caecum and the vermiform appendix during the fetal period in human fetuses and the relation between growing and shape of the caecum and the localization of the vermiform appendix. 40 male and 40 female externally normal-looking fetuses were studied between 10 and 40 weeks of gestation and were subdivided into fetuses of the 1st, 2nd, and 3rd trimesters and full-term fetuses. The parameters of interest included covering of the caecum with peritoneum, shape of the caecum (long tube, symmetric saccule, asymmetric saccule, extremely large right side--atypical), axial length and width of the caecum localization of the vermiform appendix, length of vermiform appendix and length of the meso-appendix. There was a difference in covering of the caecum with peritoneum between males and females; the caecum was predominantly tube shaped during the fetal period, with the asymmetric saccule towards the end of the fetal period; the localization of the vermiform appendix was subcaecal (39%) during the fetal period and postileal (34%) in female fetuses and subcaecal (48%) in male fetuses--the localization of the vermiform appendix changed according to the caecum shape during the fetal period; we found significant differences in the measurements of vermiform appendix, meso-appendix, and caecum among 1st-, 2nd-, and 3rd-trimester fetuses and full-term fetuses. There was an increase in the measurements for vermiform appendix, meso-appendix, and caecum with increasing gestational age; the localization of the vermiform appendix depended on the shape of the caecum, was different from that of adults and different between sexes, and there was also a significant difference in covering of the caecum with peritoneum between both sexes.

    Full Text Available BACKGROUND: Atopic dermatitis (AD is a common inflammatory and chronically relapsing disorder with increasing prevalence. However, little is known about its prevalence in Shanghai, the top metropolitan of China. This study will estimate and compare the prevalence of AD in urban and rural areas in representative samples of 3 to 6-year-old children in Shanghai. METHODOLOGY/PRINCIPAL FINDINGS: A descriptive cross-sectional study was performed. Pre-school children were obtained by cluster sampling from 8 communities in different districts in Shanghai. The main instrument was the core questionnaire module for AD used in the U.K. Working Party's study. All the data were statistically analyzed by EpiData 3.1 and SPSS16.0. A total of 10,436 children completed the study satisfactorily, with a response rate of 95.8%. The prevalence of AD in 3 to 6-year-old children was 8.3% (Male: 8.5%, Female: 8.2%. The prevalence in urban areas of Shanghai was gradiently and significantly higher than that in rural areas. The highest prevalence was in the core urban area (10.2% in Xuhui Tianping vs. the lowest far from the urban areas (4.6% in Chongming Baozhen. CONCLUSIONS/SIGNIFICANCE: The prevalence of AD was 8.3% (95%CI: 7.6%-9.1% in children aged 3 to 6 in Shanghai. The prevalence of AD decreased from the center to the rural areas in Shanghai.

    Full Text Available Background. This study assesses the lifetime and active prevalence of epilepsy in Spain in people older than 18 years. Methods. EPIBERIA is a population-based epidemiological study of epilepsy prevalence using data from three representative Spanish regions (health districts in Zaragoza, Almería, and Seville between 2012 and 2013. The study consisted of two phases: screening and confirmation. Participants completed a previously validated questionnaire (EPIBERIA questionnaire over the telephone. Results. A total of 1741 valid questionnaires were obtained, including 261 (14.99% raising a suspicion of epilepsy. Of these suspected cases, 216 (82.75% agreed to participate in phase 2. Of the phase 2 participants, 22 met the International League Against Epilepsy’s diagnostic criteria for epilepsy. The estimated lifetime prevalence, adjusted by age and sex per 1,000 people, was 14.87 (95% CI: 9.8–21.9. Active prevalence was 5.79 (95% CI: 2.8–10.6. No significant age, sex, or regional differences in prevalence were detected. Conclusions. EPIBERIA provides the most accurate estimate of epilepsy prevalence in the Mediterranean region based on its original methodology and its adherence to ILAE recommendations. We highlight that the lifetime prevalence and inactive epilepsy prevalence figures observed here were compared to other epidemiological studies.

    New psychoactive substances are conquering the drug scene. Police seize different colourful packages with exceptional names. They are declared as 'bath salts', 'plant food', or 'research chemical powders'. Little is known about the actual prevalence of these drugs. Reanalysis of hair samples from routine cases concerning the presence of new psychoactive substances or 'smart drugs' should provide insight into changing patterns of designer drugs. All hair samples from 2009 and 2010 that originally tested positive for amphetamines or MDMA (N = 325) were reanalyzed for new or smart drugs such as 4-fluoroamphetamine, piperazines (BZP, mCPP and TFMPP), cathinones (4-MMC (mephedrone), methylone, butylone, ethylone, MDPV, methcathinone and cathinone), methylphenidate and ketamine. Hair snippets were extracted using a two-step extraction procedure. The analytes were analyzed using liquid chromatography-tandem mass spectrometry (LC-MS/MS) (electrospray ionization; multiple-reaction-monitoring mode - information dependent acquisition - enhanced product ion scan). New psychoactive substances were found in 120 cases (37%). Concerning the piperazine drugs, mCPP was positive in 34 (10.5%) cases and TFMPP in one case. Five mCPP cases were also positive for trazodone, an antidepressant which is metabolized to mCPP. In 11 (3%) cases, 4-MMC was detected. Concerning the smart drugs, methylphenidate was found in 16 (5%). Ketamine was found in 45 (14%) cases. 4-Fluoroamphetamine was identified in 12 (4%) cases and methylone in one case.In conclusion, there is a high prevalence of these drugs. Consequently, at least the most common ones (e.g. mCPP, KET, 4-MMC and 4-FA) should be included in screening procedures in clinical and forensic toxicology. Copyright © 2012 John Wiley & Sons, Ltd.

    This document contains Appendix E: Toxicity Information and Uncertainty Analysis, description of methods, from the combined Remedial Investigation/Feasibility Study Report for the Clinch River/Poplar Crack (CR/PC) Operable Unit (OU). The CR/PC OU is located in Anderson and Roane Counties, Tennessee and consists of the Clinch River and several of its embayments in Melton Hill and Watts Bar Reservoirs. These waters have received hazardous substances released over a period of 50 years from the US Department of Energy`s Oak Ridge Reservation (ORR), a National Priority List site established under the Comprehensive Environmental Response, Compensation, and Liability Act. A remedial investigation has been conducted to determine the current nature and extent of any contamination and to assess the resulting risk to human health and the environment. The feasibility study evaluates remedial action alternatives to identify any that are feasible for implementation and that would effectively reduce risk. Historical studies had indicated that current problems would likely include {sup 137}Cs in sediment of the Clinch River, mercury in sediment and fish of Poplar Creek and PCBs and pesticides in fish from throughout the OU. Peak releases of mercury and {sup 137}Cs occurred over 35 years ago, and current releases are low. Past releases of PCBs from the ORR are poorly quantified, and current releases are difficult to quantify because levels are so low. The site characterization focused on contaminants in surface water, sediment, and biota. Contaminants in surface water were all found to be below Ambient Water Quality Criteria. Other findings included the following: elevated metals including cesium 137 and mercury in McCoy Branch sediments; PCBs and chlordane elevated in several fish species, presenting the only major human health risk, significant ecological risks in Poplar Creek but not in the Clinch River.

    To determine the prevalence of adverse food reactions (AFRs) in dogs with dermatological signs presented to the referral dermatological clinic of the University of Milan. The medical records of dogs with dermatological signs were reviewed. Prevalence of AFRs was calculated. Owner and clinician pruritus scores were compared. Breed, sex and age predisposition were statistically tested, as was the association between AFR and selected clinical features. The prevalence of AFRs in dogs with dermatological signs was 12% (16 of 130). AFR was diagnosed in 26% of dogs with allergic disease and 48% of those subjected to a dietary trial. There was a significant association between AFRs and early onset of clinical signs (dogs with perianal fistulas were German shepherd dogs. The prevalence of AFRs in the study population was higher than most reported values. Further studies are warranted to investigate the true prevalence of AFR and its possible association with perianal fistula and other potential markers.

    The aim of the present study was to estimate the associations between the prevalence of asthma symptoms in schoolchildren and meteorological variables in west European countries that participated in the International Study of Asthma and Allergies in Children (ISAAC), Phase III 1997-2003. An ecologic study was carried out. The prevalence of asthma was obtained from this study from 48 centers in 14 countries, and meteorological variables from those stations closest to ISAAC centers, together with other socioeconomic and health care variables. Multilevel mixed-effects linear regression models were used. For schoolchildren aged 6-7 years, the prevalence rate of asthma decreased with an increase in mean annual sunshine hours, showed a positive association with rainy weather, and warm temperature, and a negative one with relative humidity and physician density (PD). Current wheeze prevalence was stronger in autumn/winter seasons and decreased with increasing PD. Severe current wheeze decreased with PD. For schoolchildren aged 13-14 years, the prevalence rates of asthma and current wheeze increased with rainy weather, and these rates decreased with increased PD. Current wheeze, as measured by a video questionnaire, was inversely associated with sunny weather, and nurse density. Severe current wheeze prevalence was stronger during autumn/winter seasons, decreased with PD, and indoor chlorinated public swimming pool density, and increased with rainy weather. Meteorological factors, including sunny and rainy weather, and PD may have some effect on the prevalence rates of asthma symptoms in children from west European countries.

    Attention deficit/hyperactivity disorder (ADHD) is an increasingly recognized comorbid condition in subjects with substance use disorders (SUDs). This paper describes the methods and study population of the International ADHD in Substance Use Disorders Prevalence (IASP) study. Objectives of the IASP are to determine the prevalence of ADHD in adult treatment seeking patients with SUD in different countries and SUD populations, determine the reliability and validity of the Adult ADHD Self-report Scale V 1.1 (ASRS) as ADHD screening instrument in SUD populations, investigate the comorbidity profile of SUD patients with and without ADHD, compare risk factors and protective factors in SUD patients with and without a comorbid diagnosis of ADHD, and increase our knowledge about the relationship between ADHD and the onset and course of SUD. In this cross-sectional, multi-centre two stage study, subjects were screened for ADHD with the ASRS, diagnosed with the Conner's Adult ADHD Diagnostic Interview for DSM-IV (CAADID), and evaluated for SUD, major depression, bipolar disorder, anti social personality disorder and borderline personality disorder. Three thousand five hundred and fifty-eight subjects from 10 countries were included. Of these 40.9% screened positive for ADHD. This is the largest international study on this population evaluating ADHD and comorbid disorders. Copyright © 2013 John Wiley & Sons, Ltd.

    Full Text Available The objective of this study was to assess the prevalence of mucositis and peri-implantitis associated with the use of two types of implants—conventional versus platform switching after one year of loading. A longitudinal study of 64 implants in 25 patients was performed. Clinical variables, such as clinical pocket depth and bleeding upon probing, plaque, mobility, gingival recession, clinical attachment loss, and radiographic bone loss, were analyzed. The case definition for peri-implantitis was established as pockets of ≥ 5 mm with bleeding and bone loss ≥ 2 mm. One year after implant loading, the prevalence of mucositis and peri-implantitis with conventional implants (CIs was 81.2% and 15.6%, respectively. For platform switching implants (PSIs the prevalence was 90% and 6.6%, respectively. These differences were not statistically significant (p = 0.5375. However, there was a trend towards a lower prevalence of peri-implantitis with platform switching Implants.

    Data on chronic pancreatitis prevalence are scanty and usually limited to hospital-based studies. Investigating chronic pancreatitis prevalence in primary care. Participating primary care physicians reported the prevalence of chronic pancreatitis among their registered patients, environmental factors and disease characteristics. The data were centrally reviewed and chronic pancreatitis cases defined according to M-ANNHEIM criteria for diagnosis and severity and TIGAR-O classification for etiology. Twenty-three primary care physicians participated in the study. According to their judgment, 51 of 36.401 patients had chronic pancreatitis. After reviewing each patient data, 11 turned out to have definite, 5 probable, 19 borderline and 16 uncertain disease. Prevalence was 30.2/100.000 for definite cases and 44.0/100.000 for definite plus probable cases. Of the 16 patients with definite/probable diagnosis, 8 were male, with mean age of 55.6 (±16.7). Four patients had alcoholic etiology, 5 post-acute/recurrent pancreatitis, 6 were deemed to be idiopathic. Four had pancreatic exocrine insufficiency, 10 were receiving pancreatic enzymes, and six had pain. Most patients had initial stage and non-severe disease. This is the first study investigating the prevalence of chronic pancreatitis in primary care. Results suggest that the prevalence in this context is higher than in hospital-based studies, with specific features, possibly representing an earlier disease stage.

    Inherited ichthyoses represent a group of rare skin disorders characterized by scaling, hyperkeratosis and inconstant erythema, involving most of the tegument. Epidemiology remains poorly described. This study aims to evaluate the prevalence of inherited ichthyosis (excluding very mild forms) and its different clinical forms in France. Capture - recapture method was used for this study. According to statistical requirements, 3 different lists (reference/competence centres, French association of patients with ichthyosis and internet network) were used to record such patients. The study was conducted in 5 areas during a closed period. The prevalence was estimated at 13.3 per million people (/M) (CI95%, [10.9 - 17.6]). With regard to autosomal recessive congenital ichthyosis, the prevalence was estimated at 7/M (CI 95% [5.7 - 9.2]), with a prevalence of lamellar ichthyosis and congenital ichthyosiform erythroderma of 4.5/M (CI 95% [3.7 - 5.9]) and 1.9/M (CI 95% [1.6 - 2.6]), respectively. Prevalence of keratinopathic forms was estimated at 1.1/M (CI 95% [0.9 - 1.5]). Prevalence of syndromic forms (all clinical forms together) was estimated at 1.9/M (CI 95% [1.6 - 2.6]). Our results constitute a crucial basis to properly size the necessary health measures that are required to improve patient care and design further clinical studies.

The worldwide prevalence of MS in the adult population is on the rise and Bangladesh is no exception. According to some epidemiological study, MS is highly prevalent in Bangladesh and has increased dramatically in last few decades. To provide a clear picture of the current situation, we conducted a systematic review and meta-analysis with an objective to assess the prevalence of metabolic syndrome among the Bangladeshi population using data already published in the scientific literature. We searched MEDLINE, EMBASE and PubMed and manually checked references of all identified relevant publications that described the prevalence of MS in Bangladesh. Random effects meta-analysis was used to pool the prevalence. Heterogeneity was explored using formal tests and subgroup analyses. Study quality and publication bias was also explored. Electronic and grey literature search retrieved 491 potentially relevant papers. After removing duplicates, reviewing titles and abstracts and screening full texts, 10 studies were finally selected. Most of the studies were conducted in rural populations and study participants were mostly females. The weighted pooled prevalence of metabolic syndrome regardless of gender and criteria used to define metabolic syndrome, was 30.0% with high heterogeneity observed. Weighted pooled prevalence of metabolic syndrome is higher in females (32%) compared to males (25%) though not statistically significant (p = 0.434). Prevalence was highest (37%) when Modified NCEP ATP III criteria was used to define MS, while it was lowest (20%) when WHO criteria was used. In most cases, geographical area (urban/rural) was identified as a source of heterogeneity between the studies. Most of the studies met study quality assessment criteria's except adequate sample size

    Full Text Available Objective: The need for immigration usually depends on complicated relations between economical, social, familial and political factors. Unavailability to education, occupation, services and respecting to primary human rights are the most important factors in immigration. Materials & Methods: This study designed and performed for detection of frequency of depression in Afghan refugees in Bardsir’s camp. In this survey 300 persons (162 female, 138 male of that camp were selected. They filled out Beck's depression inventory and demographic questionnaire. The method of sampling was cluster sampling and the study was cross-sectional. Results: Total prevalence of depression in these refugees was 53%. The most severity of depression was in age group 20-29 years. Statistically there was no significant difference between depression and age. The relation between the prevalence of depression and sex was studied (57% in female and 47.8% in male. Statistically there was a significant between the prevalence of depression and sex (P<0.04. Depression rate among single people was more than married people, but the relation between the prevalence of depression and marital status was not significant. The most severity of depression in relation with refuges duration was found in the people with refuges period of 141-150 months. Conclusion: Generally the prevalence of depression among refugees except sex doesn't relate with demographic factors and mainly the factors after migration affected the prevalence of depression.

  7. Prevalence of hypertension in Indian tribes: a systematic review and meta-analysis of observational studies.

    S A Rizwan

    Full Text Available In India there is an increasing trend in hypertension prevalence among the general population. Studies have shown that tribal populations in India are also experiencing this burden.The aim was to estimate the pooled prevalence of primary hypertension among adult tribal populations of India.A systematic search was conducted in MEDLINE, IndMed, Web of Science, Google Scholar and major journals for studies published between 1981 and 2011. Two authors independently reviewed the studies, did quality assessment and extracted data in pre-coded spread-sheets. Pooled estimates of prevalence of hypertension were calculated using DerSimonian-Laird random effects model. Subgroup and sensitivity analyses and meta-regression were performed.Twenty studies or 53 subpopulations with 64 674 subjects were included in final review. The pooled estimate of hypertension prevalence was 16.1% (95% CI: 13.5, 19.2. There was significant heterogeneity among the studies (I2 = 99% and Q = 4624.0, df  = 53, p<0.001. Subgroup analyses showed that year of study, acculturation status, special features, and BP measurement techniques significantly influenced prevalence, but after meta-regression analyses, 'decade of study' remained the only covariate that significantly and independently influenced prevalence (R2 = 0.57, Q = 119.2, df  = 49, p value <0.001.An increasing trend was found in the prevalence of hypertension in adult tribal populations across three decades. Although acculturation was probably the underlying agent that caused this increase, other unmeasured factors that need further research were also important. Concerned policy makers should focus on the changing health needs of tribal communities.

    Western diets are associated with obesity, vascular diseases, and metabolic syndrome and might increase dementia risk in later life. If these associations are causal, those low- and middle-income countries experiencing major changes in diet might also see an increasing prevalence of dementia. To investigate the relationship of dietary supply and the prevalence of dementia in mainland China, Hong Kong, and Taiwan over time using existing data and taking diagnostic criteria into account. Estimated total energy supply and animal fat from the United Nations was linked to the 70 prevalence studies in mainland China, Hong Kong, and Taiwan from 1980 to 2012 according to the current, 10 years, and 20 years before starting year of investigation. Studies using newer and older diagnostic criteria were separated into two groups. Spearman's rank correlation was calculated to investigate whether trends in total energy, animal fat supply, and prevalence of dementia were monotonically related. The supply of total energy and animal fat per capita per day in China increased considerably over the last 50 years. The original positive relationship of dietary supply and dementia prevalence disappeared after stratifying by newer and older diagnostic criteria and there was no clear time lag effect. Taking diagnostic criteria into account, there is no cross-sectional or time lag relationship between the dietary trends and changes in dementia prevalence. It may be too early to detect any such changes because current cohorts of older people did not experience these dietary changes in their early to mid-life.

    Patent foramen ovale (PFO) can cause ischemic stroke because of paradoxical embolism. Autopsy studies have shown that the prevalence of PFO is 25% in whites or blacks. However, there is a paucity of data on the prevalence of PFO in Asians. The aim of this study was to clarify the prevalence of PFO in the Japanese population. We reviewed 52,717 autopsy reports, which were collected and edited by the Japanese Society of Pathology from 2009 to 2012. Next, we inspected consecutive 103 formalin-fixed specimens that had already been examined by certified pathologists from 2009 to 2013 to find PFO and atrial septal aneurysm (ASA). ASA was defined as ≥10 mm protrusion of the septum into the left or the right atrium. In the database of the Japanese Society of Pathology, the incidence of PFO was 0.08% (43/52,717). Inspection of heart specimens disclosed that the prevalence of PFO was 13.6% (14/103). None of the PFO cases was reported at the original autopsy. PFO was more frequently found in the subjects with ASA (50%) than in those without ASA (9.7%) (P=0.004). PFO is under-reported in autopsy reports. Re-evaluation of heart specimens disclosed that the prevalence of PFO was 13.6%. The prevalence was lower than reported in the past.

    This study was carried out to estimate toothache prevalence among adult residents in Kerman. This cross-sectional, population-based study was conducted among individuals aged over 18 years (n=1800). The relevant data on the prevalence of toothache and associated factors were collected by interviewing the individuals in their homes and filling out a questionnaire designed by the examiners. Prevalence of toothache and associated factors that patients recalled previous to their interview were analyzed by chi-square test and multivariate logistic regression analysis. Nine hundred ninety-one individuals (55.1%) reported toothache during the 6 months before the interview. The participants who flossed daily, had regular dental visits, and had higher education showed a significantly lower prevalence of toothache (Pdental floss (OR=1.5), or having a mental or psychological illness (OR=1.5) were more likely to have a history of toothache. High prevalence of toothache (more than half) among residents of Kerman shows a serious and major public health problem. Toothache prevalence in middle aged adults, lower education, bigger family size, lower dental hygiene habit and/or those having mental or psychological illness were more common in the city of Kerman.

    This retrospective study was performed to investigate the prevalence of the idiopathic osteosclerosis (IO) in Korean malocclusion patients according to age, sex, and the Angle's classification of malocclusion. This study consisted of 2,001 randomly selected patients from the Department of Orthodontics at the Gangneung-Wonju National University Dental Hospital, Korea. The prevalence of IO in Korean malocclusion patients was recorded using their panoramic radiographs, and the following parameters were surveyed; age, sex, and the Angle's classification of malocclusion. The chi-square test was analyzed to determine the statistical significance of differences in the prevalence of IO between age, sex, and the Angle's classification of malocclusion. The prevalence of IO in the jaws was 6.7% in a total of 2,001 examined orthodontic patients. The majority of IO was found in the mandible (96.58%). The 30-39 age group showed the highest prevalence of IO (9.60%). There was a higher prevalence in females (6.89%) than in males (6.45%). The prevalence of IO in Angle Class I group (7.07%) was the most frequent, followed by Angle Class II group (6.72%), and Angle Class III group (6.40%). However, there was no statistical significance in sex and Angle's classification of malocclusion. The prevalence of IO in malocclusion patients showed the differences between various age groups and most of them were found in the mandibular posterior area. However, sex and the type of malocclusion are not to be considered as a contributing factor of IO.

    The prevalence of gastroesophageal reflux disease (GERD) is consistently lower in the Chinese than in white populations. Population-based data tracking the time trend of GERD prevalence in Chinese subjects is conflicting. This study examines the population prevalence, risk factors, and time trend associated with GERD in a Chinese population. A population-based cross-sectional study utilizing a validated GERD questionnaire administered by a telephone survey was performed on 3360 Chinese subjects from Hong Kong. GERD prevalence rates in 2011 were compared with prevalence rates in 2002 and 2006. Multiple logistic regressions were performed to determine the risk factors associated with weekly GERD. A total of 2074 subjects (mean age, 48.1±18.2 y; range 18 to 94; 63.1% female) completed the survey (response rate 61.7%). The prevalence of GERD as defined by the Montreal definition was 3.8%. The prevalence of weekly GERD had increased by 1.3% between 2002 and 2011, which represents an at least 50% relative increase (PGERD was associated with noncardiac chest pain [odds ratio (OR), 1.7; 95% confidence interval (CI), 1.034-2.9; P=0.037], dyspepsia (OR, 5.1; 95% CI, 3.0-8.8; PGERD rates in the ethnic Chinese have risen over the last decade. Despite this, variables associated with a survey diagnosis of GERD remain ostensibly unchanged. GERD research in East Asia should focus on the factors driving the rapid rise in prevalence rates and the association with more atypical symptoms of GERD.

    The PREDATORR (PREvalence of DiAbeTes mellitus, prediabetes, overweight, Obesity, dyslipidemia, hyperuricemia and chronic kidney disease in Romania) study is the first national study analyzing the prevalence of diabetes mellitus (DM) and prediabetes, and their association with cardiometabolic, sociodemographic, and lifestyle risk factors in the Romanian population aged 20-79 years. This was an epidemiological study with a stratified, cross-sectional, cluster random sampling design. Sociodemographic, lifestyle, and anamnestic data were collected through self- and interviewer-administered questionnaires, and biochemical assays and oral glucose tolerance tests were performed. In all, 2728 participants from 101 clinics of general practitioners were randomly selected, with a probability proportional to population size according to the 2002 Romanian Census. The participation rate was 99.6%. Impaired glucose regulation (prediabetes, known and unknown DM) was found in 28.1% of the study population. The overall age- and sex-adjusted prevalence of DM was 11.6% (95% CI 9.6%-13.6%), of which 2.4% (95% CI 1.7%-3.1%) had unknown DM. The prevalence of DM increased with age and was higher in men than in women. The age- and sex-adjusted prevalence of prediabetes was 16.5% (95%CI 14.8%-18.2%), with the highest percentage in the 60-79 year age group and in women. Obesity, abdominal obesity, dyslipidemia, low education level, and a family history of diabetes were associated with glucose metabolism disorders. The PREDATORR study shows a high prevalence of impaired glucose regulation in the adult Romanian population, providing data on the prevalence of DM and prediabetes and their association with several risk factors. © 2015 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and John Wiley Sons & Australia, Ltd.

    The objective of this study was to examine: (1) the prevalence of diagnosed Tourette syndrome in Canada by sex in youth (aged 12-17) and adults and (2) socioeconomic factors in this population. The majority of epidemiological studies of tics have focused on children and youth, with few studies describing the prevalence of tics in adult populations. Canadian data on Tourette syndrome prevalence were derived from the Canadian Community Health Survey 2010 and 2011 cycles, a Statistics Canada population-based cross-sectional survey that collects information related to health status. We determined the prevalence of diagnosed Tourette syndrome and examined sociodemographic factors, including age, sex, education, income, employment, and birthplace. Overall, 122,884 Canadians participated in the surveys, with 122 participants diagnosed with Tourette syndrome. The prevalence of Tourette syndrome was higher in males in youth: 6.03 per 1000 (95% confidence interval: 3.24-8.81) in males versus 0.48 per 1,000 (95% confidence interval: 0.05-0.91) in females, with a prevalence risk ratio of 5.31 (95% confidence interval: 2.38-11.81). In adults, the prevalence of Tourette syndrome was 0.89 per 1,000 (95% confidence interval: 0.48-1.29) in males versus 0.44 (95% confidence interval: 0.16.0-0.71) in females, with a prevalence risk ratio of 1.93 (95% confidence interval: 1.21-3.08). After adjusting for age and sex, adults with Tourette syndrome had lower odds of receiving postsecondary education or being employed and higher odds of having income lower than the median and receiving governmental support. Data on the prevalence of Tourette syndrome in adults are scarce because most studies focus on children. Our data demonstrate a decreasing prevalence risk ratio for sex in adults compared to children. A diagnosis of Tourette syndrome is associated with lower education, income, and employment in adulthood. © 2016 International Parkinson and Movement Disorder Society. © 2016

    Full Text Available Background: A previous hospital based study from Delhi revealed a high prevalence of hypothyroidism in pregnant women. Several other studies with small sample size also indicate a rising trend of prevalence of hypothyroidism during pregnancy in India. Objective: To assess prevalence of hypothyroidism in pregnant women from various states/cities across India. Materials and Methods: This was a cross-sectional multicenter study conducted at Allahabad (Uttar Pradesh, Bengaluru (Karnataka, Chennai (Tamil Nadu, Kolkata (West Bengal, Hyderabad (Telangana, Nasik (Maharashtra, Rohtak (Haryana, Pune (Maharashtra, New Delhi (Delhi, Srinagar (Kashmir, and Vizag (Andhra Pradesh enrolling 2599 pregnant women. Estimation of thyroid stimulating hormone (TSH, free T4, and antithyroid peroxidase (TPO antibodies was carried out using Roche modular kit using ECLIA technology in a central laboratory. Results: We found in our study population that 13.13% of pregnant women have hypothyroidism (n = 388, using a cutoff TSH level of 4.5 μIU/ml. This prevalence was much higher using the American Thyroid Association criteria. Anti-TPO antibodies were positive in 20.74% of all pregnant women (n = 613, whereas 40% (n = 155 of hypothyroid pregnant women were positive for anti-TPO antibodies. Conclusion: This study concludes that there is a high prevalence of hypothyroidism (13.13%, majority being subclinical in pregnant women during the first trimester from India and universal screening of hypothyroidism may be desirable in our country.

    Geographical variations in atopic sensitization in Canada have not been described previously. This study used the standardized protocol of the European Community Respiratory Health Survey-1 (ECRHS-1) to investigate the distribution and predictors of atopic sensitization in six sites across Canada and to compare the results with some ECRHS-1 centers. Adults aged 20-44 years in six study sites across Canada underwent allergy skin testing using 14 allergens (Dermatophagoides pteronyssinus, Dermatophagoides farinae) cat, cockroach, grasses (Timothy grass, Kentucky grass), molds (Cladosporium herbarium, Alternaria alternata, Aspergillus fumigatus, Penicillium), trees (tree mix, birch, Olea europea), and common ragweed. The overall prevalence of atopy (skin test over 0 mm to any allergen) was 62.7%. There was significant geographical variation in the prevalence of atopy in the six study sites (lowest 55.6% [95% C.I.51.3-59.9] in Prince Edward Island, highest 66.0 [61.7-70.3] in Montreal) and of sensitization to each of the allergens tested even after adjustment for confounders. When the first eight of the nine allergens in the ECRHS were used to estimate the prevalence of atopic sensitization, the prevalence of atopy in Canada was 57% compared with 35.2% overall for centers in the ECRHS. The prevalence of atopy in Vancouver (57% [52.3-61.8]) was close to that of Portland, Oregon (52.1% [46.2-58.0]). There was a significant variation in atopic sensitization among different study sites across Canada. The prevalence of atopic sensitization is relatively high in Canada compared with sites in the ECRHS and this may, in part, account for the high prevalence of asthma and asthma symptoms in Canada. © 2010 John Wiley & Sons A/S.

    Full Text Available The prevalence of metabolic syndrome has been increasing in Korea and has been associated with dietary habits. The aim of our study was to identify the relationship between dietary patterns and the prevalence of metabolic syndrome. Using a validated food frequency questionnaire, we employed a cross-sectional design to assess the dietary intake of 1257 Korean adults aged 31 to 70 years. To determine the participants' dietary patterns, we considered 37 predefined food groups in principal components analysis. Metabolic syndrome was defined according to the National Cholesterol Education Program Adult Treatment Panel III. The abdominal obesity criterion was modified using Asian guidelines. Prevalence ratios and 95% confidence intervals for the metabolic syndrome were calculated across the quartiles of dietary pattern scores using log binomial regression models. The covariates used in the model were age, sex, total energy intake, tobacco intake, alcohol consumption, and physical activity. The prevalence of metabolic syndrome was 19.8% in men and 14.1% in women. The PCA identified three distinct dietary patterns: the 'traditional' pattern, the 'meat' pattern, and the 'snack' pattern. There was an association of increasing waist circumference and body mass index with increasing score in the meat dietary pattern. The multivariate-adjusted prevalence ratio of metabolic syndrome for the highest quartile of the meat pattern in comparison with the lowest quartile was 1.47 (95% CI: 1.00-2.15, p for trend = 0.016. A positive association between the prevalence of metabolic syndrome and the dietary pattern score was found only for men with the meat dietary pattern (2.15, 95% CI: 1.10-4.21, p for trend = 0.005. The traditional pattern and the snack pattern were not associated with an increased prevalence of metabolic syndrome. The meat dietary pattern was associated with a higher prevalence of metabolic syndrome in Korean male adults.

    Prevalence estimates of ankylosing spondylitis vary considerably, and there are few nationwide estimates. The present study aimed to describe the national prevalence of clinically diagnosed ankylosing spondylitis in Sweden, stratified according to age, sex, geographical, and socio-economic factors, and according to subgroups with ankylosing spondylitis-related clinical manifestations and pharmacological treatment. All individuals diagnosed with ankylosing spondylitis according to the World Health Organization International Classification of Disease codes, between 1967 and 2009, were identified from the National Patient Register. Data regarding disease manifestations, patient demographics, level of education, pharmacological treatment, and geographical region were retrieved from the National Patient Register and other national registers. A total of 11,030 cases with an ankylosing spondylitis diagnosis (alive, living in Sweden, and 16 to 64 years old in December 2009) were identified in the National Patient Register, giving a point prevalence of 0.18% in 2009. The prevalence was higher in northern Sweden, and lower in those with a higher level of education. Men had a higher prevalence of ankylosing spondylitis (0.23% versus 0.14%, P ankylosing spondylitis of 0.18%. It revealed phenotypical and treatment differences between the sexes, as well as geographical and socio-economic differences in disease prevalence.

    To assess the types of maintenance fluids used in our hospital, comparing their volume and composition to the standards recommended by the guidelines. Observational, cross-sectional study. Volume and type of fluid therapy administered during 24h to patients admitted to various hospital departments were recorded. Patients receiving fluid therapy because of water-electrolyte imbalance were excluded. Out of 198 patients registered, 74 (37.4%) were excluded because they did not meet the criteria for inclusion. Mean administered volume was 2,500cc/day. Mean daily glucose dose was 36g per 24h (SD: 31.4). The most frequent combination included normal saline solution (NSS) and glucose 5% (64.4%). Mean daily dose of sodium and chlorine was, respectively, 173mEq (SD: 74.8) and 168mEq (SD: 75), representing a surplus daily dose of +87.4mEq and +85mEq. Potassium, magnesium and calcium daily deficit was, respectively, -50mEq, -22mEq and -21mEq per day. Buffer administration was exceptional, bicarbonate (2.29%), acetate (1.29%), lactate (1.15%) and gluconate (1.10%) being the buffering agents most frequently used. NNS is the most frequently used solution. In contrast to excess doses of sodium and chlorine, there is a great deficit of other ions, buffering agents and caloric intake in the fluid therapy regimens that are usually prescribed.

    To obtain national estimates of youth involved in sexting in the past year (the transmission via cell phone, the Internet, and other electronic media of sexual images), as well as provide details of the youth involved and the nature of the sexual images. The study was based on a cross-sectional national telephone survey of 1560 youth Internet users, ages 10 through 17. Estimates varied considerably depending on the nature of the images or videos and the role of the youth involved. Two and one-half percent of youth had appeared in or created nude or nearly nude pictures or videos. However, this percentage is reduced to 1.0% when the definition is restricted to only include images that were sexually explicit (ie, showed naked breasts, genitals, or bottoms). Of the youth who participated in the survey, 7.1% said they had received nude or nearly nude images of others; 5.9% of youth reported receiving sexually explicit images. Few youth distributed these images. Because policy debates on youth sexting behavior focus on concerns about the production and possession of illegal child pornography, it is important to have research that collects details about the nature of the sexual images rather than using ambiguous screening questions without follow-ups. The rate of youth exposure to sexting highlights a need to provide them with information about legal consequences of sexting and advice about what to do if they receive a sexting image. However, the data suggest that appearing in, creating, or receiving sexual images is far from being a normative behavior for youth.

    Elder abuse is an important public health and human rights issue, yet its true extent is not well understood. To address this, we will conduct a systematic review and meta-analysis of elder abuse prevalence studies from around the world. This protocol describes the methodological approach to be adopted for conducting this systematic review and meta-analysis. In particular, the protocol describes the search strategies and eligibility criteria to be used to identify and select studies and how data from the selected studies will be extracted for analysis. The protocol also describes the analytical approach that will be used to calculate pooled prevalence estimates and discusses the use of meta-regression to assess how studies' characteristics influence the prevalence estimates. This protocol conforms to the Preferred Reporting Items for Systematic reviews and Meta-Analysis - or PRISMA - guidelines and has been registered with the PROSPERO International Prospective Register of systematic reviews.

    Full Text Available OBJECTIVE: To report the prevalence of metabolic syndrome (MetS as found by the Central American Diabetes Initiative (CAMDI study for five major Central American populations: Belize (national; Costa Rica (San José; Guatemala (Guatemala City; Honduras (Tegucigalpa; and Nicaragua (Managua. METHODS: Study data on 6 185 adults aged 20 years or older with anthropometric and laboratory determination of MetS from population-based surveys were analyzed. Overall, the survey response rate was 82.0%. MetS prevalence was determined according to criteria from the Adult Treatment Panel III of the National Cholesterol Education Program. The study's protocol was reviewed and approved by the bioethical committee of each country studied. RESULTS: The overall standardized prevalence of MetS in the Central American region was 30.3% (95% confidence interval (CI: 27.1-33.4. There was wide variability by gender and work conditions, with higher prevalence among females and unpaid workers. The standardized percentage of the population free of any component of MetS was lowest in Costa Rica (9.0%; CI: 6.5-11.4 and highest in Honduras (21.1%; CI: 16.4-25.9. CONCLUSIONS: Overall prevalence of MetS in Central America is high. Strengthening surveillance of chronic diseases and establishing effective programs for preventing cardiovascular diseases might reduce the risk of MetS in Central America.

    In a prospective necropsy study, the prevalence of the Wernicke-Korsakoff syndrome (WKS) in Sydney, Australia was 2.1% of adults over the age of 15 years. The population studied encompassed a wide spectrum of socio-economic and cultural backgrounds. Abuse of alcohol appeared to be the major predisposing factor to the development of the WKS in cases which were adequately documented. This high prevalence rate is in line with other clinical and pathological Australian studies and provides additional support for the idea of prevention of the WKS by the use of thiamin supplements in the Australian diet in flour, bread and perhaps alcoholic beverages.

    In the present study, we coined the term 'alveolar dome' and aimed to demonstrate the prevalence of alveolar domes through digital periapical radiographs. This study examined 800 digital periapical radiographs in regard to the presence of alveolar domes. The periapical radiographs were acquired by a digital system using a photostimulable phosphor (PSP) plate. The χ2 test, with a significance level of 5%, was used to compare the prevalence of alveolar domes in the maxillary posterior teeth and, considering the same teeth, to verify the difference in the prevalence of dome-shaped phenomena between the roots. The prevalence of alveolar domes present in the first pre-molars was statistically lower as compared to the other maxillary posterior teeth (p<0.05). No statistically significant difference was observed in the prevalence of alveolar domes between the maxillary first and second molars. Considering the maxillary first and second molars, it was observed that the palatal root presented a lower prevalence of alveolar domes when compared to the distobuccal and mesiobuccal roots (p<0.05). The present study coined the term 'alveolar dome', referring to the anatomical projection of the root into the floor of the maxillary sinus. The maxillary first and second molars presented a greater prevalence of alveolar domes, especially in the buccal roots, followed by the third molars and second pre-molars. Although the periapical radiograph is a two-dimensional method, it can provide dentists with the auxiliary information necessary to identify alveolar domes, thus improving diagnosis, planning, and treatment.

    The PORMETS study was designed to estimate the prevalence of metabolic syndrome and its determinants in the overall and administrative regions of the Portuguese mainland. A cross-sectional study of a representative sample of non-institutionalized Portuguese adults selected from primary health care centres lists including 1695 men and 2309 women was conducted from February 2007 to July 2009. A structured questionnaire was administered, collecting information on personal medical history and socio-demographic and behavioural characteristics. Anthropometrics, blood pressure, and venous blood samples were obtained. Metabolic syndrome was defined according to three operational definitions. The prevalence ratios and their respective 95% confidence intervals were calculated using binomial generalized linear regression, with the log link function. The prevalence rates of metabolic syndrome in this sample of Portuguese adults were 36.5%, 49.6%, and 43.1%, using the Adult Treatment Panel III, International Diabetes Federation and Joint Interim Statement definitions, respectively. The most prevalent feature of metabolic syndrome in this sample was high blood pressure (64.3%) and the lowest was high fasting glucose (24.9%). After adjustment for age and gender, significant differences were observed for the 18 districts of the Portugal mainland. Additionally, metabolic syndrome was significantly more frequent in non-urban areas than in urban ones (p = 0.001). The prevalence of metabolic syndrome was significantly higher in women (p˂0.001) and older participants (p˂0.001), as well as in those who reported being housewives (p = 0.010), retired (p = 0.046) or unemployed (p = 0.024). This study showed that metabolic syndrome is highly prevalent in the Portuguese adult population. Regional differences in the prevalence of this syndrome were observed, and this condition was more common in non-urban areas and less favoured socio-economic categories.

    Full Text Available INTRODUCTION: Obesity is a worldwide public health issue. Since the epidemiological behaviour of this disease is not well established in our country, the purpose of this study was to determinate its prevalence in the Maracaibo City, Zulia State- Venezuela. MATERIALS AND METHODS: A cross-sectional study was undertaken using the data set from the Maracaibo City Metabolic Syndrome Prevalence Study. The sample consists of 2108 individuals from both genders and randomly selected: 1119 (53.09% women and 989 (46.91% men. The participants were interrogated for a complete clinical history and anthropometric measurements. To classify obesity, the WHO criteria for Body Mass Index (BMI, and Waist Circumference (WC from the IDF/NHLBI/AHA/WHF/IAS/IASO-2009 (IDF-2009 and ATPIII statements were applied. RESULTS: For BMI, obesity had an overall prevalence of 33.3% (n = 701, and according to gender women had 32.4% (n = 363 and men had 34.2% (n = 338. Overweight had a prevalence of 34.8% (n = 733, Normal weight had 29.8% (n = 629, and Underweight had 2.1% (n = 45. Adding Obesity and Overweight results, the prevalence of elevated BMI (>25 Kg/m(2 was 68.1%. Using the IDF-2009 WC's cut-off, Obesity had 74.2% prevalence, compared to 51.7% using the ATPIII parameters. CONCLUSIONS: These results show a high prevalence of abdominal obesity in our locality defined by the WHO, IDF-2009 and ATPIII criteria, which were not designed for Latin-American populations. We suggest further investigation to estimate the proper values according to ethnicity, genetic background and sociocultural aspects.

    The Pacific Northwest Loads and Resources Study (WhiteBook), is published annually by BPA, and establishes the planning basis for supplying electricity to customers. It serves a dual purpose. First, the White Book presents projections of regional and Federal system load and resource capabilities, along with relevant definitions and explanations. Second, the White Book serves as a benchmark for annual BPA determinations made pursuant to the 1981 regional power sales contracts. Specifically, BPA uses the, information in the White Book for determining the notice required when customers request to increase or decrease the amount of power purchased from BPA. Aside from these purposes, the White Book is used for input to BPA`s resource planning process. The White Book compiles information obtained from several formalized resource planning reports and data submittals, including those from the Northwest Power Planning Council (Council) and the Pacific Northwest Utilities Conference Committee (PNUCC).

    Full Text Available Abstract Background Several studies conducted during the 1990s indicated that childhood allergic diseases were increasing worldwide, but more recent investigations in some Western countries have suggested that the trend is stabilizing or may even be reversing. However, few data are available on the current status of allergic disease prevalence in Chinese children. The aim of the present study was to investigate the prevalence rates of asthma, allergic rhinitis, and eczema in children of three major cities of China, to determine the status of allergic diseases among Chinese children generally, and to evaluate the prevalence of allergic diseases in children of different ages. Methods We conducted a cross-sectional survey between October 2008 and May 2009 in three major cities of China (Beijing, Chongqing, and Guangzhou to evaluate the prevalence rates of childhood allergic diseases including asthma, allergic rhinitis, and eczema, using a questionnaire of the International Study of Asthma and Allergies in Childhood (ISAAC group. A total of 24,290 children aged 0-14 years were interviewed, using a multi-stage sampling method. To acquire data on children aged 3-14 years, we visited schools and kindergartens. To access children too young to attend school or kindergarten, we extended our survey to community health service centers. Each questionnaire was completed by a parent or guardian of a child after an informed consent form was signed. Results Of the 24,290 children in our study, 12,908 (53.14% were males and 11,382 (46.86% females; 10,372 (42.70% were from Beijing, 9,846 (40.53% from Chongqing, and 4,072 (16.77% from Guangzhou. Our survey indicated that in Beijing, Chongqing, and Guangzhou, the prevalence rates of asthma were 3.15%, 7.45%, and 2.09%, respectively; the rates of allergic rhinitis were 14.46%, 20.42%, and 7.83%; and the rates of eczema were 20.64%, 10.02%, and 7.22%. The prevalence of allergic diseases varied with age. Asthma was

    Depression is a common health problem, ranking third after cardiac and respiratory diseases as a major cause of disability. There is evidence to suggest that university students are at higher risk of depression, despite being a socially advantaged population, but the reported rates have shown wide variability across settings. To explore the prevalence of depression in university students. PubMed, PsycINFO, BioMed Central and Medline were searched to identify studies published between 1990 and 2010 reporting on depression prevalence among university students. Searches used a combination of the terms depression, depressive symptoms, depressive disorders, prevalence, university students, college students, undergraduate students, adolescents and/or young adults. Studies were evaluated with a quality rating. Twenty-four articles were identified that met the inclusion and exclusion criteria. Reported prevalence rates ranged from 10% to 85% with a weighted mean prevalence of 30.6%. The results suggest that university students experience rates of depression that are substantially higher than those found in the general population. Study quality has not improved since 1990.

    Full Text Available Hypertension is one of the leading causes of disease burden across the world. In China, the latest nationwide survey of prevalence of hypertension was ten year ago, and data in rural areas is little known. More information about hypertension prevalence could help to improve overall antihypertensive health care. We aimed to estimate the pooled prevalence of hypertension in rural areas of China.Comprehensive electronic searches of PubMed, Web of Knowledge, Chinese Web of Knowledge, Wangfang, Weipu and SinoMed databases were conducted to identify any study in each database published from January 1, 2004 to December 31, 2013, reporting the prevalence of hypertension in Chinese rural areas. Prevalence estimates were stratified by age, area, sex, publication year, and sample size. All statistical calculations were made using the Stata Version 11.0 (College Station, Texas and Statsdirect Version 2.7.9.We identified 124 studies with a total population of 3,735,534 in the present meta-analysis. Among people aged 18 years old in Chinese rural areas, the summarized prevalence is 22.81% (19.41%-26.41%. Subgroup analysis shows the following results: for male 24.46% (21.19%-27.89%, for female 22.17% (18.25%-26.35%. For 2004-2006: 18.94% (14.41%-23.94%, for 2007-2009, 21.24% (15.98%-27.01% for 2010-2013: 26.68%, (20.79%-33.02%. For Northern region 25.76% (22.36%-29.32%, for Southern region 19.30%, (15.48%-24.08%.The last decade witnessed the growth in prevalence of hypertension in rural areas of China compared with the fourth national investigation, which has climbed the same level as the urban area. Guidelines for screening and treatment of hypertension in rural areas need to be given enough attention.

    In recent years, there has been a marked change in life-style of South Asian countries caused by economic growth, affluence, urbanization and dietary westernization. Few studies on the prevalence of obesity, hypertension and diabetes in the Indian population have been reported. However, there has been scarce literature on the study of prevalence of type 2 diabetes mellitus (DM) and Hypertension in overweight and obese people in India with criteria suggested by World Health Organization (WHO) for Asians. Information on such public health issues would provide evidence based data to develop guidelines and policies on this subject. The aim of this article is to determine the prevalence of hypertension and type 2 DM in overweight and obese people. A cross-sectional study consisted of people selected from the out-patient department and indoors of a large defense hospital in a semi urban area of Assam. Patients with overweight and obesity, reporting for consultation and medical examination were taken into the study. The data collected was analyzed using the criteria for overweight, obesity, diabetes and hypertension defined by WHO, Joint National Committee VII and International Diabetes Federation, American Diabetes Association. A descriptive statistical analysis has been carried out in the study. A total of 300 people were the subject population of this study. Among the subject population, there were 97 overweight and 203 obese. The 56 subjects were found to be diabetic. The prevalence of type 2 DM in overweight subjects was 15.5% and in obese was 20.2% and overall was 18.7%. Prevalence of hypertension in the overweight population was 8.2% and in obese was 22.2% and overall found to be 17.7%. The prevalence of type 2 DM, hypertension in the obese group of the study population were found to be 20.2%, 22.2% and in the overweight population were 15.5% and 8.2%, respectively.

    Recurrent syncope of obscure etiology, particularly in those with structural heart diseases, is associated with higher mortality rates. There are insufficient and conflicting data on prevalence and etiology of syncope in the urban Middle Eastern population. Evaluating the etiologic basis of syncope can be an effective step in prevention of morbidities and sudden cardiac death in susceptible populations. The aim of our study was to determine the prevalence and etiology of syncope in an outpatient cardiology clinic in Tehran the capital of Iran. In this cross sectional study data was collected from patients' records whose first visits were from March 2006 to September 2007 and had undergone thorough examination for syncope (ECG, Holter monitoring, echocardiography, Tilt table testing, Electrophysiological study). All efforts were done to determine underlying heart diseases, physical exam and test abnormalities, final diagnosis and treatment in all selected patients. Overall prevalence of syncope was estimated to be 9%. The age-specific prevalence rates were 5-14 years:  4.14%, 15-44 years: 44.8%, 45-64 years: 31%, 65 years and Older: 20%. The most frequently identified cause (60%) was neurally-mediated (vasovagal) syncope. Mean age of patients was 44.9 years with a minimum of 5 years and maximum of 85 years. In our study, coronary heart disease had a high prevalence among participants (12.4%). Syncope is a common clinical problem. In this study prevalence rates peaked in 15-44 years age group. Considering that recurrent syncope is often disabling and may cause injury and the fact that heart diseases are more common in people affected by syncope, especial cautions should be taken while evaluating this group of patients.

    Full Text Available More than 80% cardiovascular disease (CVD is preventable despite the fact that it is currently the ultimate cause of disability in the world. Assessment of the nationwide prevalence of dyslipidemia as a major CVD risk factor is essential to efficiently conduct prevention programs. We extracted data according to the cut-off points of dyslipidemia used in each study. All published papers on this topic in Iranian and international journals with affiliation of "Iran" were reviewed using standard keywords up to September 2011. We included all available population-based studies and national surveys conducted in individuals aged ≥ 15 years. We excluded studies with < 300 individuals, non-population-based studies, or duplicated citations. We analyzed by random effect method due to between-study heterogeneity. The estimated prevalence and 95% confidence intervals in 29 eligible articles and one un-published data for hypercholesterolemia (≥200 mg/dl, hypertriglyceridemia (≥150 mg/dl, high levels of low density lipoprotein cholesterol ([LDL-C] [ ≥ 130 mg/dl] and low levels of high density lipoprotein cholesterol ([HDL-C] <40 mg/dl in males, <50 mg/dl in females, in Iranian people were 41.6% (36.1-47.0, 46.0% (43.3-48.7, 35.5% (24.0-47.1 and 43.9% (33.4-54.4, respectively among both sexes and in both rural and urban areas. Hypercholesterolemia, high LDL-C and low HDL-C were more prevalent in women, whereas hypertriglyceridemia was more prevalent in men. All types of lipid component abnormalities were more prevalent in urban residents. Prevalence of dyslipidemia is considerable in Iran. It is necessary to enforce current measures of dyslipidemia control in the Iranian people to reduce CVD burden.

    We aimed to determine the prevalence and associations of refractive error on Norfolk Island. Population-based study on Norfolk Island, South Pacific. All permanent residents on Norfolk Island aged ≥ 15 years were invited to participate. Patients underwent non-cycloplegic autorefraction, slit-lamp biomicroscope examination and biometry assessment. Only phakic eyes were analysed. Prevalence and multivariate associations of refractive error and myopia. There were 677 people (645 right phakic eyes, 648 left phakic eyes) aged ≥ 15 years were included in this study. Mean age of participants was 51.1 (standard deviation 15.7; range 15-81). Three hundred and seventy-six people (55.5%) were female. Adjusted to the 2006 Norfolk Island population, prevalence estimates of refractive error were as follows: myopia (mean spherical equivalent ≥ -1.0 D) 10.1%, hypermetropia (mean spherical equivalent ≥ 1.0 D) 36.6%, and astigmatism 17.7%. Significant independent predictors of myopia in the multivariate model were lower age (P refractive error were increasing age (P prevalence of myopia on Norfolk Island is lower than on mainland Australia, and the Norfolk Island population demonstrates ethnic differences in the prevalence estimates. Given the significant associations between refractive error and several ocular biometry characteristics, Norfolk Island may be a useful population in which to find the genetic basis of refractive error. © 2011 The Authors.

    Full Text Available Abstract Background Hypospadias is a congenital displacement of the urethral meatus in male newborns, being either an isolated defect at birth or a sign of sexual development disorders. The aim of this study was to assess the prevalence rate of hypospadias in different Districts of Italy, in order to make a comparison with other countries all over the world. Methods We reviewed all the newborns file records (years 2001–2004 in 15 Italian Hospitals. Results We found an overall hypospadias prevalence rate of 3.066 ± 0.99 per 1000 live births (82.48% mild hypospadias, 17.52% moderate-severe. In newborns Small for Gestational Age (birthweight th percentile of any gestational age the prevalence rate of hypospadias was 6.25 per 1000 live births. Performing multivariate logistic regression analysis for different degrees of hypospadias according to severity, being born SGA remained the only risk factor for moderate-severe hypospadias (p = 0.00898 but not for mild forms (p > 0.1. Conclusion In our sample the prevalence of hypospadias results as high as reported in previous European and American studies (3–4 per 1000 live births. Pathogenesis of isolated hypospadias is multifactorial (genetic, endocrine and environmental factors: however, the prevalence rate of hypospadias is higher in infants born small for gestational age than in newborns with normal birth weight.

    Full Text Available Background/objective: The anatomy of vermiform appendix displays great variations in length and position between different populations. The reports relating these variations to a specific etiological factor are few. This study aims to describe the positions and lengths of vermiform appendix among Sudanese cadavers. Methods: This descriptive study was carried out in Omdurman Teaching Hospital Morgue and Omdurman Islamic University-Sudan. Sixty Sudanese cadavers (30 male and 30 female, were dissected in the period from June 2013 to June 2014. The positions and the lengths of vermiform appendix were measured in millimeters. The data was analyzed by SPSS version 20. Results: The cadavers’ age ranged between 20 to 80 years according to their medico-legal reports. Retrocaecal position was mainly observed in 60%, pelvic in 35%, post-ileal in 3.3%, and pre-ileal in 1.7%. The lengths of the appendix was found < 69 mm in 23.3%, 70-110 mm in 60%, and > 110 mm in 16.7%, also the study showed insignificant difference between the lengths and ages (p < 0.08, and between males and females (p = 0.23. Age was the influencing factor for the positions of vermiform appendixes (p = 0.04. Conclusion: The study showed that the commonest lengths of the appendix were 70-110 mm while the common position was retrocaecal regardless to age or gender. This data should be considered in surgical removal of the inflamed appendix.

    To estimate the prevalence of refractive errors in adult Chinese Americans, and to evaluate factors associated with myopia and high myopia. A population-based, cross-sectional study. Chinese Americans 50 years and older residing in Monterey Park, California, were recruited. Noncycloplegic automated refraction with supplemental subjective refraction was performed. Myopia, high myopia, hyperopia, and high hyperopia were defined as a spherical equivalent of +0.5 D, and ≥+3.0 D, respectively. Astigmatism and high astigmatism were defined as a cylinder of >0.5 D and >2.25 D, respectively. Risk factor assessment was guided by a conceptual model. Data from 4144 participants were analyzed. The overall prevalence of myopia, high myopia, hyperopia, high hyperopia, astigmatism, and high astigmatism in the right eye was 35.1% (95% confidence interval, 33.6%-36.6%), 7.4% (6.6%-8.3%), 40.2% (38.7%-41.8%), 2.7% (2.2%-3.3%), 45.6% (44.1%-47.2%), and 3.7% (3.1%-4.3%), respectively. The prevalence of myopia and high myopia was lower among older individuals (P refractive errors (P prevalence of refractive errors, except for a higher prevalence of hyperopia among female subjects (P = .010). Age, acculturation, education, income, marital status, birth country, history of ocular disease, nonocular comorbidities, and recent eye examination were associated with prevalence of myopia. All of these factors, except for acculturation, were also associated with high myopia. Our data present the first population-based estimates of the prevalence of refractive errors among adult Chinese Americans. Compared with whites, Hispanics, and blacks, Chinese Americans have a higher burden of myopia, high myopia, and astigmatism. Copyright © 2016 Elsevier Inc. All rights reserved.

    Population-based data for diabetic hand syndrome (DHS) are limited. The aim of the present epidemiological study was to estimate the overall and cause-specific prevalence and rate ratio (RR) of DHS in patients with diabetes. The present study was a cross-sectional study based on a random sample of 57 093 diabetics and matched controls, both identified from Taiwan National Health Insurance claims in 2010. The DHS analyzed in the present study included carpal tunnel syndrome (CTS), stenosing flexor tenosynovitis (SFT), limited joint mobility (LJM), and Dupuytren's disease (DD). The prevalence of overall DHS was estimated at 2472 per 10 5 for the diabetics, compared with 1641 per 10 5 for the controls, representing a prevalence RR of 1.51 (95 % confidence interval [CI] 1.39-1.64). Stratified analyses further revealed that the significantly increased prevalence of overall DHS was more evident in females than males (1.59 vs 1.36) and was only noted in diabetics aged ≥35 years. Cause-specific analysis suggested that patients with diabetes had the highest prevalence of CTS (1244 per 10 5 ), followed by SFT (1209 per 10 5 ), LJM (39 per 10 5 ), and DD (6 per 10 5 ). In addition, diabetes was only significantly associated with CTS (RR 1.34; 95 % CI 1.20-1.51) and SFT (1.74; 95 % CI 1.54-1.97). The prevalence of overall and certain cause-specific DHS was significantly elevated in patients with diabetes in Taiwan. © 2016 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

    To determine the prevalence of amblyopia and its determinants in a population-based study in Mashhad County, Iran. This cross-sectional, population-based study was conducted on the population of Mashhad County aged >1 year using randomized stratified cluster sampling. Examinations were performed after selection of the participants and their free transportation to the sampling site. The examinations included the measurement of uncorrected and corrected visual acuity, cycloplegic and non-cycloplegic refraction, cover testing, slit-lamp biomicroscopy, and ophthalmoscopy. In this study, amblyopia was defined as best corrected visual acuity (BCVA) of 20/30 or less or 2-line interocular optotype acuity differences with no pathology. After considering the exclusion criteria, the data of 2739 individuals, 65.6% of whom were women, were analyzed. The mean age of the participants was 29.5±17.5 years. The prevalence of amblyopia was 4.6% (95% CI: 3.77%-5.43%) in the total population. The lowest prevalence was 2.24% in the age group 5-15 years (95% CI: 0.99%-3.48%) and the highest prevalence was 7.14% in the age group 55-65 years (95% CI: 2.64%-11.56%). Anisometropic amblyopia was observed in 45.24% of the amblyopic participants. Isometropic, mixed (strabismic/anisometropic), and strabismic amblyopia were other common causes of amblyopia, with a prevalence of 24.6%, 16.67%, and 13.49% in amblyopic patients, respectively. The odds ratio (OR) of having amblyopia for each 1-year increase in age was 1.02 (95% CI: 1.01-1.03). Amblyopia was less common in people with better socioeconomic status. This study showed the prevalence of amblyopia in all age groups in a population-based study for the first time. The findings of this study regarding the relatively high prevalence of amblyopia in the older population and its lower prevalence in young people indicate attention to amblyopia in recent years.

    Full Text Available Background: Intellectual disability (ID is a permanent and highly disabling condition. The birth of a disabled child induces complex feelings in mother and other family members. This study was planned to investigate phenomenology of ID and the prevalence of depression in their mothers. Objective: To find prevalence, influence of various sociodemographic variables, and its clinical correlation with depression in mothers of ID children. Study Design: A cross-sectional study. Materials and Methods: A total of 100 patients diagnosed as ID were included in the study. Objective data were collected in a special Pro forma, and mothers of these patients were evaluated with the Beck's Anxiety Inventory and Beck's Depression Inventory. Results: The mean age of patients with ID was 11.52 years, had received an average of 3.01 years of schooling, mean age at diagnosis was 6.01 years, mean intelligence quotient was 45.17, and 79% had significant comorbidities. The prevalence of depression in mothers was 79%; it was more in mothers of female ID child, ID child with significant comorbidities, severer forms of retardation, and with higher levels of anxiety in the mother. Conclusions: The prevalence of depression in mothers of ID children in the present study seems to be much greater than those reported from the previous studies. The determination of predictors of depression among mothers of ID children may help health professionals in identifying mothers at risk. Regular screening of mothers of ID children should be included in the protocol for management.

    Full Text Available Background: Wushu is one of the martial arts that combines explosive strength and speed movements with combat techniques. Most studies to date of wushurelated injuries have been published in Chinese languages. No published studies have reported the prevalence of these injuries in Iran. Therefore, the aim of the present study was to determine the prevalence of musculoskeletal injuries in male wushu players in Shiraz. Methods: Male wushu athletes aged 18 to 30 years were included in this cross sectional study if they had been practicing for 2 hours per session, twice a week during the past 3 years. The athletes were recruited by convenience sampling from 30 wushu clubs in Shiraz, Iran. The sample size was 165. The study was conducted from June to September 2016. Each participant was asked to complete an information questionnaire about his musculoskeletal injuries related to wushu during the previous year. Results: About two third (65.45% of wushu players had one or more injuries during the previous year. Severe injuries were most commonly located in the head/neck and knee/tibia areas, and inflammation was more prevalent than the other types of injuries. Conclusion: Wushu players in this study reported a high prevalence of injuries affecting different parts of the body.

    Full Text Available BACKGROUND Obesity is defined as having excess body fat due to ‘calorie imbalance’ -too few calories expended for the amount of calories consumed. Childhood obesity has both immediate and long-term effects on health and well-being. This study is aimed to highlight the burden of obesity among school children. The objectives of this study are to find the prevalence of obesity among school children aged 11-15 years and to compare prevalence of obesity among school children of government and private schools. MATERIALS AND METHODS School-based cross-sectional study conducted in 2 private and 2 government schools of a rural area in Trivandrum district. Total 800 students (200 from each school aged 11-15 years in 6 th to 10 th standards were selected by systematic random sampling and consent were obtained. Height (cm and weight (kg were measured using stadiometer and standardised weighing machine, respectively. Body Mass Index (BMI was calculated and categorised as underweight, normal, overweight and obese. The prevalence is expressed in percentages. RESULTS In this study, the total prevalence of overweight and obesity among the total 800 school children is found to be 4% and 1%, respectively. An alarming incidental finding is that the underweight prevalence is 61%, which is significantly high and should be addressed. The overall prevalence of overweight and obesity is 4.25% and 1.75%, respectively in private schools, whereas it is 3.5% and 1%, respectively, in government schools. There is not a significant difference between private and government school children. This may be due to the awareness about problems of obesity and its effects among school children and also timely health checkups in the schools. CONCLUSION This study done in a rural area found that there is a significant prevalence of obesity and overweight as well as a very high prevalence of underweight. It indicates that childhood obesity is an emerging health problem in rural areas

    Full Text Available Background: Hypothyroidism is believed to be a common health issue in India, as it is worldwide. However, there is a paucity of data on the prevalence of hypothyroidism in adult population of India. Materials and Methods: A cross-sectional, multi-centre, epidemiological study was conducted in eight major cities (Bangalore, Chennai, Delhi, Goa, Mumbai, Hyderabad, Ahmedabad and Kolkata of India to study the prevalence of hypothyroidism among adult population. Thyroid abnormalities were diagnosed on the basis of laboratory results (serum FT3, FT4 and Thyroid Stimulating Hormone [TSH]. Patients with history of hypothyroidism and receiving levothyroxine therapy or those with serum free T4 5.50 μU/ml, were categorized as hypothyroid. The prevalence of self reported and undetected hypothyroidism, and anti-thyroid peroxidase (anti-TPO antibody positivity was assessed. Results: A total of 5376 adult male or non-pregnant female participants ³18 years of age were enrolled, of which 5360 (mean age: 46 ± 14.68 years; 53.70% females were evaluated. The overall prevalence of hypothyroidism was 10.95% (n = 587, 95% CI, 10.11-11.78 of which 7.48% (n = 401 patients self reported the condition, whereas 3.47% (n = 186 were previously undetected. Inland cities showed a higher prevalence of hypothyroidism as compared to coastal cities. A significantly higher ( P 5.50 μIU/ml. Anti - TPO antibodies suggesting autoimmunity were detected in 21.85% (n = 1171 patients. Conclusion: The prevalence of hypothyroidism was high, affecting approximately one in 10 adults in the study population. Female gender and older age were found to have significant association with hypothyroidism. Subclinical hypothyroidism and anti-TPO antibody positivity were the other common observations.

    Alcohol consumption is considered a risk factor for sarcopenia, but the association between alcohol consumption and the prevalence of sarcopenia has not been evaluated in detail. This study was to identify the relationship between alcohol drinking patterns and the prevalence of sarcopenia in the elderly Korean population. The cross-sectional study was performed using data from the Korea National Health and Nutrition Examination Survey. Participants were excluded if they were under the age of 65, or if data was not available regarding skeletal muscle mass or dietary intake. After these exclusions, a total of 4020 participants (men: 1698; women: 2322) were analyzed in the present study. Sarcopenia is defined according to the criteria for the Asia Working Group for Sarcopenia (AWGS). Binge drinking was defined as consuming ≥5 standard alcoholic drinks (≥4 drinks for women) consecutively on one occasion. This data was subcategorized into two groups based on presence of binge drinking: Social drinking (≤1 time/month) and binge drinking (>1 time/month). Women binge drinkers with weekly or daily consumption had 2.8 times higher prevalence of sarcopenia than social drinkers (Odds Ratio [OR] = 2.84; 95% Confidence Interval [CI] = 1.12-7.29). However, there were no associations between binge drinkers and sarcopenia in men. After adjusting for age, body mass index (BMI), energy intake, moderate physical activity, and energy intake, women binge drinkers with weekly or daily alcohol consumption had 3.9 times higher prevalence of sarcopenia than social drinkers (OR = 3.88; 95% CI = 1.33-11.36). The prevalence of sarcopenia in elderly women was related to binge drinking frequency and amounts of drinking after adjusting for covariates. Elderly Korean women who binge drink once or more per week may be associated with sarcopenia, as seen with the observed 3.9 times higher prevalence compared to social drinkers.

    Full Text Available Abstract Background Physical activity (PA is one of the most important factors for improving population health, but no standardised systems exist for international surveillance. The International Physical Activity Questionnaire (IPAQ was developed for international surveillance. The purpose of this study was a comparative international study of population physical activity prevalence across 20 countries. Methods Between 2002–2004, a standardised protocol using IPAQ was used to assess PA participation in 20 countries [total N = 52,746, aged 18–65 years]. The median survey response rate was 61%. Physical activity levels were categorised as "low", "moderate" and "high". Age-adjusted prevalence estimates are presented by sex. Results The prevalence of "high PA" varied from 21–63%; in eight countries high PA was reported for over half of the adult population. The prevalence of "low PA" varied from 9% to 43%. Males more frequently reported high PA than females in 17 of 20 countries. The prevalence of low PA ranged from 7–41% among males, and 6–49% among females. Gender differences were noted, especially for younger adults, with males more active than females in most countries. Markedly lower physical activity prevalence (10% difference with increasing age was noted in 11 of 19 countries for males, but only in three countries for women. The ways populations accumulated PA differed, with some reporting mostly vigorous intensity activities and others mostly walking. Conclusion This study demonstrated the feasibility of international PA surveillance, and showed that IPAQ is an acceptable surveillance instrument, at least within countries. If assessment methods are used consistently over time, trend data will inform countries about the success of their efforts to promote physical activity.

    We assessed the prevalence of neck pain in the population in relation to headache. In a cross-sectional study, a total of 797 individuals completed a headache interview and provided self-reported data on neck pain. We identified migraine, TTH or both migraine and TTH (M+TTH) groups. Pericranial tenderness was recorded in 496 individuals. A total tenderness score (TTS) was calculated as the sum of local scores with a maximum score of 48. The one-year prevalence of neck pain was 68.4% and higher in those with vs. without primary headache (85.7% vs. 56.7%; adjusted OR 3.0, 95% CI 2.0-4.4, pneck pain (56.7%) was significantly higher in those with M+TTH (89.3%), pure TTH (88.4%) and pure migraine (76.2%) (pneck pain had higher TTS than individuals without neck pain (15.1±10.5 vs. 8.4±8.0, pNeck pain is highly prevalent in the general population and even more prevalent in individuals with primary headaches.

    To determine the prevalence of molar incisor hypomineralization (MIH) in Indian children and to analyze the possible etiological factors. First permanent molars and all permanent incisors were examined in 1,369 children aged 8 to 12 years. Examinations were performed by two calibrated observers. The subjects were evaluated using judgment criteria proposed by Weerheijm et al in 2003. The parents accompanying children were given a questionnaire regarding pre- and postnatal history of the children. A total of 191 children were diagnosed with MIH with a prevalence of 13.9%. Chi-square/Fisher exact test was used to compare the dichotomous variables. The relative risk with its 95% confidence interval was calculated to find the risk of clinical infections, such as chicken pox, jaundice, renal disorders, cardiac disorders, and affected molars with sex and type of delivery. Pre- and postnatal history of infection in a child was significantly correlated with the prevalence of MIH. The prevalence of MIH was 13.9% in the age group of 8 to 12 years. Prenatal and postnatal infections play an important role in hypomineralization of molars and incisors. How to cite this article: Mishra A, Pandey RK.

    2009-01-01

    We performed a multicenter prevalence study of nontuberculous mycobacteria (NTM) involving 1,582 patients (mean age, 18.9 years; male/female ratio, 1.06) with cystic fibrosis in France. The overall NTM prevalence (percentage of patients with at least one positive culture) was 6.6% (104/1,582 patients), with prevalences ranging from 3.7% (in the east of France) to 9.6% (in the greater Paris area). Mycobacterium abscessus complex (MABSC; 50 patients) and Mycobacterium avium complex (MAC; 23 patients) species were the most common NTM, and the only ones associated with fulfillment of the American Thoracic Society bacteriological criteria for NTM lung disease. The “new” species, Mycobacterium bolletii and Mycobacterium massiliense, accounted for 40% of MABSC isolates. MABSC species were isolated at all ages, with a prevalence peak between 11 and 15 years of age (5.8%), while MAC species reached their highest prevalence value among patients over 25 years of age (2.2%).

    The absence of data on the prevalence of pilomatricoma among patients with Turner syndrome served as the catalyst for this multicenter investigation. To ascertain the prevalence of pilomatricoma among patients with Turner syndrome and to determine any association between the development of pilomatricomas and the use of exogenous hormones in patients with Turner syndrome. A retrospective medical record review from January 1, 2000, through January 1, 2010, was performed of all patients with Turner syndrome. Data on pilomatricomas and the use of hormone therapy were collected. University of California-Davis Medical Center, University of Nebraska Medical Center, and The University of North Carolina at Chapel Hill. Patients with a diagnosis of Turner syndrome. Prevalence of concomitant pilomatricoma and diagnosis of Turner syndrome. Secondary outcome measures included the use of the exogenous hormones estrogen or recombinant human growth hormone (rhGH). In total, 311 patients with Turner syndrome were identified from these 3 institutions. Among them, 8 patients (2.6%) were diagnosed as having pilomatricomas. Before the development of pilomatricomas, 5 patients had been treated with rhGH but not estrogen, 1 patient had received estrogen but not rhGH, and 2 patients did not receive either therapy. Although the prevalence of pilomatricoma among the general population is unknown, this study demonstrates a high prevalence (2.6%) of pilomatricomas among patients with Turner syndrome. No apparent relationship was noted among our patients or in the literature between the use of rhGH and the development of pilomatricomas.

    To report a pilot prevalence of maternal overweight, obesity and underweight in selected Greek counties. A total of 441 adult childbearing women were recruited from maternity clinics in 6 Greek counties for this cross-sectional study. Pre-gravid weight status was defined according to the WHO cut-offs and gravid weight status was diagnosed with the Mardones and Rosso weight gain chart. During gestation the majority of the participants were of normal body weight (BW) (34.0%), obesity was apparent in 25.6% of the sample, 23.8% of the participants were underweight, and the remaining 16.6% were overweight. Overall, pregnancy tripled the prevalence of underweight, increased the prevalence of obesity (by 388.0%) and decreased the number of participants in the normal BW category (p≤0.001 for all). The majority of participants classified in each pre-gravid weight-category remained in the same weight category during their gestation. All the pre-gravidly obese women were also obese during pregnancy. Underweight was more prevalent in Kavala (37.5%) and obesity was more frequent in Thessaloniki (30.8%). Women who were overweight prior to conception were highly likely to be overweight/obese during pregnancy (OR: 23.8, CI: 11.1-51.0). The results indicate a high prevalence of overweight, obesity and underweight among pregnant women in Greece. Copyright © 2012 SEEN. Published by Elsevier Espana. All rights reserved.

    Full Text Available Multimorbidity is a major concern in primary care. Nevertheless, evidence of prevalence and patterns of multimorbidity, and their determinants, are scarce. The aim of this study is to systematically review studies of the prevalence, patterns and determinants of multimorbidity in primary care.Systematic review of literature published between 1961 and 2013 and indexed in Ovid (CINAHL, PsychINFO, Medline and Embase and Web of Knowledge. Studies were selected according to eligibility criteria of addressing prevalence, determinants, and patterns of multimorbidity and using a pretested proforma in primary care. The quality and risk of bias were assessed using STROBE criteria. Two researchers assessed the eligibility of studies for inclusion (Kappa= 0.86.We identified 39 eligible publications describing studies that included a total of 70,057,611 patients in 12 countries. The number of health conditions analysed per study ranged from 5 to 335, with multimorbidity prevalence ranging from 12.9% to 95.1%. All studies observed a significant positive association between multimorbidity and age (odds ratio [OR], 1.26 to 227.46, and lower socioeconomic status (OR, 1.20 to 1.91. Positive associations with female gender and mental disorders were also observed. The most frequent patterns of multimorbidity included osteoarthritis together with cardiovascular and/or metabolic conditions.Well-established determinants of multimorbidity include age, lower socioeconomic status and gender. The most prevalent conditions shape the patterns of multimorbidity. However, the limitations of the current evidence base means that further and better designed studies are needed to inform policy, research and clinical practice, with the goal of improving health-related quality of life for patients with multimorbidity. Standardization of the definition and assessment of multimorbidity is essential in order to better understand this phenomenon, and is a necessary immediate step.

    2016-01-01

    The aim of this study was to identify risk factors and estimate prevalence of depressive episodes among Wroclaw's universities students. Polish adaptation of the Composite International Diagnostic Interview (CIDI) was implemented to gather epidemiological data from 370 students of public universities in Wroclaw. Proportional stratified sampling was performed to obtain distinct, independent strata representing sex, year of study and educational profiles. Randomisation was ensured by recruitment procedures. Prevalence of depressive episodes among students in Wroclaw is high - 14.7% throughout life, 9.8% within 12 months prior to the interview. High prevalence of severe and moderate depressive episodes seems to be worrisome (respectively 5.1% and 6.6% throughout life, 3.8% and 3.9% within 12 months prior to the study). Year of study, profile and lack of partner relationship remain risk factor for depression. High prevalence of depressive episodes indicates the need for prevention and therapy based on epidemiological data and tailored to the students' needs. Depression among students requires further epidemiological studies.

    2010-08-01

    The aim of this review was to examine design and reporting issues that affect prevalence estimates of leg ulceration obtained using self-report and outline strategies to strengthen the validity and reliability of research in this area. We identified leg ulcer prevalence studies and evaluated them against the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) statement. The authors draw upon the wider literature and their own empirical work in discussing strategies to overcome design and reporting issues. Common deficiencies in the design and reporting of studies include wide variations in diagnostic criteria and age parameters for participant selection, a lack of description of efforts to address bias/study size rationale, and low participation rates in clinical examination stages. These factors and differences in statistical methods of analysis affect the validity and reliability of findings and hinder interpretation, making comparisons across populations difficult. Opportunities for subgroup analyses are frequently missed. Self-report is a valuable means of capturing leg ulcer prevalence, but the future design and reporting of studies need to be strengthened, including addressing weaknesses in validation strategies. Capture-recapture analysis or a multiple-methods approach has the potential to yield the most valid and reliable prevalence estimates. Copyright (c) 2010 Elsevier Inc. All rights reserved.

    Very little is known regarding the global variations in the prevalence of food allergies. The EuroPrevall-INCO project has been developed to evaluate the prevalence of food allergies in China, India and Russia using the standardized methodology of the EuroPrevall protocol used for studies in the European Union. The epidemiological surveys of the project were designed to estimate variations in the prevalence of food allergy and exposure to known or suspected risk factors for food allergy and to compare the data with different European countries. Random samples of primary schoolchildren were recruited from urban and rural regions of China, Russia and India for screening to ascertain possible adverse reactions to foods. Cases and controls were then selected to answer a detailed questionnaire designed to evaluate the possible risk factors of food allergies. Objective evidence of sensitisation including skin-prick test and serum specific IgE measurement was also collected. More than 37 000 children from the three participating countries have been screened. The response rates for the screening phase ranged from 83% to 95%. More than 3000 cases and controls were studied in the second phase of the study. Further confirmation of food allergies by double blind food challenge was conducted. This will be the first comparative study of the epidemiology of food allergies in China, India, and Russia using the same standardized methodology. The findings of these surveys will complement the data obtained from Europe and provide insights into the development of food allergy.

    Full Text Available Obesity is one of the main public health problems which underlie many chronic illnesses and socioeconomic difficulties. According to the literature review, there are limited data on the prevalence of obesity in different parts of Iran as well as its trend and prevalence among different age and gender groups. The aim of this study was to estimate the obesity prevalence in Iran using meta-analysis. All the corresponding articles published in the external and internal journals, final reports of research projects, articles of related congresses and the reference index of the correlated papers published between 1995 and 2010 were collected via the electronic research engines (PubMed, Scopus, SID, Magiran, IranMedex.  Data were analyzed using meta-analysis (random effects model and meta-regression. A total of 144 articles with the sample size of 377858 people (134588 males and 164858 females were enrolled in the study. The prevalence of obesity in populations above the age of 18 was estimated as 21.7% (CI 95%: 18.5% - 25% and in populations below 18 as 6.1% (CI 95%: 6.8%-5.4%. Meta-regression analysis showed an ascending trend in the prevalence of obesity in Iran. The prevalence rates of obesity according to the BMI index, NCHC and percentile above 95 were 17.4%, 7.6% and7.4%, respectively. The BMI mean was 19.3 in populations below the age of 18 (CI 95%: 17-21.6 and 25.2 in those above the age of 18 (CI 95%: 27.1-23.3. Considering the increasing rate of obesity in Iran and its effects on the public health, corresponding health authorities should revise the obesity preventive programs and, using public health interventions, reduce the rate of obesity in the country.

    Few epidemiological surveys on general population samples estimated changes in prevalence of respiratory symptoms/diseases over a long time interval; our study aims to quantify the temporal changes in the prevalence rates of asthma, allergic rhinitis and Chronic Obstructive Pulmonary Disease (COPD) after 25 years from baseline. A general population sample participated in 3 cross-sectional surveys carried out in Central Italy (Pisa) in 1985-88 (n = 3865), 1991-93 (n = 2841), 2009-11 (n = 1620). 2276 (47%) subjects participated in at least 1 survey, 1723 (35.5%) in at least 2 surveys and 849 (17.5%) in all the 3 surveys. All subjects filled in a standardized questionnaire about health status and risk factors; a sub-sample performed spirometry. Chi-square test was used to compare adjusted prevalence rates of respiratory symptoms/diseases and descriptive characteristics among the surveys. Generalised estimating equations (GEE) were used to analyze the association between respiratory symptoms/diseases and risk factors. There was an increasing trend in prevalence rates of all respiratory symptoms/diseases throughout the surveys: current asthma attacks (1st-3rd survey prevalence: 3.4-7.2%), allergic rhinitis (16.2-37.4%), usual phlegm (8.7-19.5%) and COPD (2.1-6.8%) more than doubled. The GEE model confirmed these increasing trends, indicating higher risk of having respiratory symptoms/diseases in the second and third surveys. While asthma and allergic rhinitis increasing trends were confirmed, with respect to other international studies, also a COPD increasing prevalence rates was shown. Copyright © 2015 Elsevier Ltd.

    2015-01-01

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

    Somatoform disorders have rarely been addressed in epidemiological and health care services studies of the elderly. The few existing studies vary considerably in their methodologies limiting comparability of findings. Data come from the MentDis_ICF65+ study, in which a total of 3142 community-dwelling respondents aged 65-84 years from six different countries were assessed by the Composite International Diagnostic Interview adapted to the needs of the elderly (CIDI65+). The 12-month prevalence rate for any somatoform disorders was found to be 3.8, whereby the prevalence for somatization disorder according to DSM-IV was 0%, the prevalence for abridged somatization was 1.7% and the rate for 12-months somatoform pain disorder was 2.6%. We found a significant variation by study centre (p < 0.005). There was a significant gender difference for pain disorder, but not for abridged somatization. Significant age-related effects revealed for both disorder groups. Somatoform disorders were found to be associated with other mental disorders [odds ratio (OR) anxiety =4.8, OR affective disorders 3.6], as well as with several impairments and disabilities. Somatoform disorders are prevalent, highly impairing conditions in older adults, which are often associated with other mental disorders and should receive more research and clinical attention.

    Prevalences of multimorbidity vary between European studies and several methods and definitions are used. In this study we examine the prevalence of multimorbidity in relation to age, gender and educational attainment and the association between physical and mental health conditions and educational attainment in a Danish population. A cross-sectional design was used to study the prevalence of multimorbidity, defined as two or more chronic conditions, and of comorbid physical and mental health conditions across age groups and educational attainment levels among 1,397,173 individuals aged 16 years and older who lived in the Capital Region of Denmark on January 1st, 2012. After calculating prevalence, odds ratios for multimorbidity and mental health conditions were derived from logistic regression on gender, age, age squared, education and number of physical conditions (only for odds ratios for mental health conditions). Odds ratios for having multimorbidity and mental health conditions for each variable were adjusted for all other variables. Multimorbidity prevalence was 21.6%. Half of the population aged 65 and above had multimorbidity, and prevalence was inversely related to educational attainment: 26.9% (95% CI, 26.8-26.9) among those with lower secondary education versus 13.5% (95% CI, 13.5-13.6) among people with postgraduate education. Adjusted odds ratios for multimorbidity were 0.50 (95% CI, 0.49-0.51) for people with postgraduate education, compared to people with lower secondary education. Among all population members, 4.9% (95% CI, 4.9-4.9) had both a physical and a mental health condition, a proportion that increased to 22.6% of people with multimorbidity. Physical and mental health comorbidity was more prevalent in women (6.33%; 95% CI, 6.3-6.4) than men (3.34%; 95% CI, 3.3-3.4) and approximately 50 times more prevalent among older persons than younger ones. Physical and mental health comorbidity was also twice as prevalent among people with lower

    The Danish General Suburban Population Study (GESUS), the objective of which is to facilitate epidemiological and genetic research, has included the Major Depression Inventory (MDI) and the WHO-Five Well-Being Index (WHO-5) among the medical health questionnaires. We were thus in a position to compare the 2-week prevalence of ICD-10 depression in the period from 2010 to 2012 with our previous Danish general population study from 2003, in which the MDI was also included. The aim of our analysis was not only to evaluate the point prevalence of ICD-10 depression but also to describe the prevalence of antidepressants received by the respondents in the GESUS study and the correspondence to their subjective well-being on the WHO-5 questionnaire. To evaluate the validity (scalability) of the MDI and the WHO-5 in the GESUS study we performed the non-parametric Mokken analysis. The scalability of the MDI and the WHO-5 was quite acceptable. In total, 14,787 respondents were available from a response rate of 50%. The 2-week prevalence of ICD-10 depression was 2.3%, which is rather similar to the 2.8% in our 2003 study. The rate of people receiving antidepressants increased consistently with increasing severity of ICD-10 depression. This study has confirmed that the use of the MDI to obtain an ICD-10 depression diagnosis gives rather conservative estimates of the 2-week prevalence of depression in the Danish general population. The prescription of antidepressants depends on the severity of the ICD-10 depression diagnosis.

    Prostate cancer screening may detect nonprogressive cancers, leading to overdiagnosis and overtreatment. The potential for overdiagnosis can be assessed from the reservoir of prostate cancer in autopsy studies that report incidental prostate cancer rates in men who died of other causes. We aimed to estimate the age-specific incidental cancer prevalence from all published autopsy studies. We identified eligible studies by searches of Medline and Embase, forward and backward citation searches and contacting authors. We screened the titles and abstracts of all articles; checked the full-text articles for eligibility and extracted clinical and pathology data using standardized forms. We extracted mean cancer prevalence, age-specific cancer prevalence and validity measures and then pooled data from all studies using logistic regression models with random effects. The 29 studies included in the review dated from 1948 to 2013. Incidental cancer was detected in all populations, with no obvious time trends in prevalence. Prostate cancer prevalence increased with each decade of age, OR = 1.7 (1.6–1.8), and was higher in studies that used the Gleason score, OR = 2.0 (1.1–3.7). No other factors were significantly predictive. The estimated mean cancer prevalence increased in a nonlinear fashion from 5% (95% CI: 3–8%) at age 79 years. There was substantial variation between populations in estimated cancer prevalence. There is a substantial reservoir of incidental prostate cancer which increases with age. The high risk of overdiagnosis limits the usefulness of prostate cancer screening. What’s new? Before symptoms of prostate cancer manifest clinically, many men die of other causes. Yet, prostate screening, particularly in older men, frequently turns out positive, resulting in overdiagnosis and overtreatment. This meta-analysis of published autopsy studies shows that incidental prostate cancer increases with age and with the use of sensitive screening strategies

    Full Text Available Abstract Background Following reports of high prevalence of low back pain (LBP in young physiotherapists 171819202122, we investigated whether LBP was a problem for undergraduate physiotherapy students. Method Physiotherapy students enrolled in one Australian tertiary institution completed a validated self-administered questionnaire in April 2001, seeking information on LBP prevalence (lifetime, 12 month, one-month, one-week, and its risk factors. The survey incorporated the Nordic back questionnaire, questions on common risks for LBP, and purpose-built questions regarding educational exposures. Univariate logistic regression models were applied to test associations. Results and Discussion 72% students responded. LBP prevalence was 69% (lifetime, 63% (12-month, 44% (one-month, 28% (one-week. The risk of LBP increased significantly for students once they completed first year. Being aged 20 or 21 years (final year students was significantly associated with all measures of LBP, compared with the youngest students. Exposure to tertiary study of greater than two years was associated with lifetime, 12 month and one-month LBP prevalence. Spending more than 20 hours in the past month 'sitting looking down' was significantly associated with one-month LBP prevalence. Similar exposure to 'treating patients' was significantly associated with one-month and one-week LBP prevalence. Conclusions Physiotherapy students should be alerted to the likelihood of LBP and is potential causes during their training, so that they enter the workforce with reduced risk of LBP. The potential for other undergraduate students to suffer LBP should also be considered.

    Portugal has been identified as one of the countries with a high prevalence of LRRK2-G2019S, considered to be the most frequent known cause of familial and sporadic Parkinson's disease (PD). The aim of this study was to evaluate the prevalence of PD in Portugal using a door-to-door methodology. A cross-sectional study was conducted in the Portuguese community-dwelling population; that is, elderly people living in the community on their own, aged ≥50 years and resident in mainland Portugal, in two phases: (i) a questionnaire was applied to screen potential cases of PD; and (ii) screened cases were evaluated by an expert in PD to confirm diagnosis. The adjusted prevalence of PD for the Portuguese community-dwelling population aged ≥50 years was 0.24%. The estimated total number of cases of PD for the Portuguese population is 180/100 000 inhabitants. The results of this study show that a geographical region with a high frequency of a causal mutation for PD does not automatically imply a high prevalence of patients with PD. © 2017 EAN.

    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. Cross-sectional study in a public university hospital. 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. 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. 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.

    To estimate the prevalence of osteoarthritis (OA) of different joints in rural areas of Iran. From five villages of Tuyserkan County, 1565 individuals were randomly selected and were interviewed to complete the Community Oriented Programme for Control of the Rheumatic Diseases (COPCORD) Core Questionnaire. Among these cases 1192 cases with rheumatic complaints were examined by a rheumatologist and laboratory and radiology tests were performed if necessary for the diagnosis. Definition of OA in various joints, were based on American College of Rheumatology (ACR) criteria. About 20% of the study population had OA in at least one of their joints. Prevalence of OA in the knee joint was 19.34%, in hand joins was 2.66% and in the neck was 2.21%. The most common findings on physical examination of patients with knee OA, hand OA and neck OA were bony crepitus (88.9%), Heberden's nodes (73.2%) and pain on movement (59.9%), respectively. This study revealed that OA in rural areas of Iran was more frequent in comparison with urban areas of Iran. Moreover, the prevalence of OA in rural areas of Iran was higher in comparison with prevalence of OA in rural areas of other Asian countries. Similar to previous studies OA was more frequently detected in the knee joint. © 2014 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

    There are few systematic studies on the prevalence of sarcopenia using the new diagnostic criteria in different geriatric care settings. To estimate the prevalence of sarcopenia, using the European Working Group on Sarcopenia in Older People (EWGSOP) criteria in older subjects living in nursing homes and in those who attend geriatric outpatient clinics. A single country multicentre study in two samples of older subjects: patients cared for in outpatient geriatric clinics, and individuals living in nursing homes. Data collected will include demographic variables, medical history, medication, geriatric syndromes, functional status (assessment of basic and instrumental activities of daily living), mobility, cognitive status, comorbidity, quality of life, nutritional status, and laboratory parameters. For the diagnosis of sarcopenia, 4m walking speed, handgrip strength, and body composition measured by bioelectrical impedance analysis will be assessed. Using the EWGSOP algorithm, the prevalence of sarcopenia in an elderly Spanish population will be estimated. In addition, concordance and correlation between the three parameters included in the definition (muscle mass, muscle strength, and physical performance) will be analysed, using the different existing cut-off points, and examining the diagnostic accuracy of each. Finally, demographic, anthropometric and functional data that define subjects with sarcopenia will be investigated. The ELLI study should improve knowledge on the prevalence and characteristics of sarcopenia in older people in our population. Copyright © 2012 SEGG. Published by Elsevier Espana.

    To determine the prevalence of amblyopia in Denmark before and after the initiation of the Danish national preschool vision screening programme. In a population-based cross-sectional study, 3826 participants of the Danish General Suburban Population Study (GESUS) aged 20 years and older from a Danish rural municipality received a complete general health examination and an ophthalmological interview and examination. This study included a comprehensive ophthalmologic interview, measurement of best corrected visual acuity (BCVA) in each eye, Hirschberg's test for strabismus and two 45-degree retinal fundus photographs of each eye. A complete ophthalmologic examination was performed when indicated. The prevalence of monocular visual impairment (MVI) was 4.26% (95% CI, 3.66-4.95, n = 163). Amblyopia was the most common cause, accounting for 33%. The prevalence of amblyopia was 1.44% (95% CI, 1.01-1.81, n = 55), being higher among non-preschool vision screened persons compared to those who were offered (estimated 95% attendance) preschool vision screening (1.78%, n = 41, 95% CI 1.24-2.33 versus 0.44%, n = 2, 95% CI, 0.12-1.60, p = 0.024). The leading cause of amblyopia was anisometropia (45.5%, 25/55). Amblyopia was the most common cause of MVI. Following the initiation of the Danish national preschool vision screening programme, which has an approximate attendance rate of 95%, the prevalence of amblyopia decreased by fourfold. © 2014 Acta Ophthalmologica Scandinavica Foundation.

    The present cross-sectional study investigated the prevalence of sarcopenia and clarified its associated factors in 1,000 elderly participants of Japanese population-based cohorts. Exercise habit in middle age was associated with low prevalence of sarcopenia in older age, suggesting that it is a protective factor against sarcopenia in older age. The present study investigated the prevalence of sarcopenia using the European Working Group on Sarcopenia in Older People (EWGSOP) definition, and clarified the association of sarcopenia with physical performance in the elderly participants of Japanese population-based cohorts of the Research on Osteoarthritis/osteoporosis Against Disability (ROAD) study. We enrolled 1,000 participants (aged ≥65 years) from the second visit of the ROAD study who had completed assessment of handgrip strength, gait speed, and skeletal muscle mass measured by bioimpedance analysis. Presence of sarcopenia was determined according to the EWGSOP algorithm. Information collected included exercise habits in middle age. Prevalence of sarcopenia was 13.8 % in men and 12.4 % in women, and tended to be significantly higher according to increasing age in both sexes. Factors associated with sarcopenia, as determined by logistic regression analysis, were chair stand time (odds ratio [OR], 1.09; 95 % confidence interval [CI], 1.04-1.14), one-leg standing time (OR, 0.97; 95 % CI, 0.96-0.99), and exercise habit in middle age (OR, 0.53; 95 % CI, 0.31-0.90). Exercise habit in middle age was associated with low prevalence of sarcopenia in older age. Furthermore, linear regression analysis revealed that exercise habits in middle age were significantly associated with grip strength (P gait speed (P < .001), and one-leg standing time (P = .005) in older age. This cross-sectional study suggests that exercise habit in middle age is a protective factor against sarcopenia in older age and effective in maintaining muscle strength and physical performance

    Full Text Available Abstract Background Uncontrolled hypertension (HT is an established risk factor for the development of vascular diseases. Prevalence varies in different communities and no such study has been conducted in the Parsi community living in Bombay, India. The objectives of this study were to determine the prevalence, awareness, compliance to medication and control of HT in this community. Method We used a 1 in 4 random selection of subjects who were ≥ 20 years of age. A questionnaire was administered and the blood pressure (BP was measured by a doctor. HT was defined as diastolic blood pressure (DBP ≥ 90 mm Hg ± systolic pressure (SBP ≥ 140 mm Hg. Isolated systolic hypertension (ISH was defined as SBP ≥ 160 mm Hg with DBP Results 2879 subjects ≥ 20 years of age were randomly selected of which 2415 (84% participated in the study. The overall prevalence of HT in the community was 36.4%, of whom 48.5% were unaware of their hypertensive status. Of those aware of having HT, 36.4% were non-compliant with their anti-hypertensive drugs and only 13.6% had optimally controlled HT. Prevalence of ISH using the present criteria was 19.5% and 73% of hypertensives ≥ 60 years had ISH. Conclusion This study shows that prevalence of HT in the Parsi community is high and nearly half are unaware of their hypertensive status. ISH is the dominant form of HT in the elderly. Compliance to treatment is poor and optimal BP control is achieved in only a small minority. The study highlights the need for regular screening coupled with educational programs to detect and optimally treat HT in the community.

    Stroke is a leading cause of disability and death worldwide. In the absence of published population-based prevalence data, we investigated the prevalence and risk factors of stroke in a population of varying urbanization in Sri Lanka. A population-based, cross-sectional study was conducted among 2313 adults aged ≥18 years residing in Colombo, selected using a multistage, probability proportionate-to-size, cluster sampling technique. Data were collected using an interviewer-administered questionnaire. Ever diagnosis of stroke was confirmed by medical doctors based on World Health Organization criteria and corroborated by documental evidence. Of the total population (52.4% women; mean age, 44.2 years; SD, 16.6), the prevalence of stroke was 10.4 per 1000 (95% confidence interval, 6.3-14.5) with a 2:1 male:female ratio. Beyond the age of 65 years, the prevalence was higher by 6-fold among men and by 2-fold among women. Ninety two percent had developed hemiparesis, 58.3% had dysphasia, and 16.7% had loss of balance. Hypertension was the commonest risk factor (62.5%) followed by smoking (45.8%), excess alcohol (41.7%), diabetes mellitus (33.3%), and transient ischemic attack (29.2%); 79.2%, predominantly men, had ≥2 risk factors. A percentage of 58.3 had brain computed tomographic scans, of whom 85.7% had ischemic strokes. A percentage of 64.3 had to change or give up working because of stroke-related disability. Age-adjusted stroke prevalence in urban Sri Lanka lies between high-income and low-/middle-income countries. The prevalence of stroke and its risk factors were higher among men. © 2015 American Heart Association, Inc.

    Chronic viral hepatitis C (VHC) is one of the most discussed infectious diseases worldwide. The number of infected persons worldwide is approximately 170 million, and in Europe, it exceeds 9 million. The aim of this study was to determine the prevalence of antibodies to hepatitis C virus (anti-HCV prevalence) and prevalence of HCV viremia (HCV-RNA prevalence) in Latvia. A multistage randomized selection was used. A total of 42 primary care physicians (PCPs) were randomly selected from the register of PCPs from different regions of Latvia. From each PCP register, 60 subjects were selected (1651 individuals in total) and invited for the anti-HCV test with a screening method (ELISA). In case of positive results, antibodies were confirmed by the Western blot test, and all these subjects were tested for HCV-RNA by polymerase chain reaction. Of the 1459 subjects tested, 57 were positive for anti-HCV (3.9%; 95% CI 3% to 5%); 35 of them were positive for anti-HCV with a confirmatory test (2.4%; 95% CI, 1.7% to 3.3%): 19 men and 16 women (3.8% and 1.7%, respectively; P=0.011). The results of HCV RNA test were positive in 25 subjects (1.7%; 95% CI, 1.2% to 2.5%): 15 men and 10 women (3% and 1% respectively, P=0.019). The prevalence of anti-HCV and HCV-RNA in Latvia was found to be 2.4% and 1.7%, respectively. The prevalence of anti-HCV and HCV-RNA was higher in men than women.

    To determine the prevalence of refractive errors in a multiethnic Asian population aged over 40 years and to examine secular trends and racial differences. A total of 10,033 adults (3353 Chinese, 3400 Indians, and 3280 Malays) participated in this study. Refractive error was determined by subjective refraction. Ocular biometric parameters were determined by partial coherence interferometry. Myopia and high myopia were defined as spherical equivalent (SE) of less than -0.5 diopters (D) and -5.0 D, respectively. Hyperopia was defined as SE of more than 0.5 D. Astigmatism was defined as cylinders less than -0.5 D. The prevalence of myopia, high myopia, hyperopia and astigmatism in Singapore adults aged over 40 years was 38.9% (95% confidence interval [CI] 37.1, 40.6); 8.4% (95% CI 8.0, 8.9); 31.5% (95% 30.5, 32.5); and 58.8% (95% CI 57.8, 59.9), respectively. Compared with the Tanjong Pagar Survey 12 years ago, there was a significant increase in the prevalence of astigmatism and mean axial length (AL) in Chinese adults aged over 40 years in Singapore. Chinese were most likely to be affected by myopia, high myopia, astigmatism, and had the longest AL among the three racial groups. The prevalence of myopia in Singapore adults is lower compared with the younger "myopia" generation in Singapore. The prevalence of astigmatism and mean AL have been increasing significantly within the past 12 years in the Chinese population. Chinese adults had higher prevalence of myopia, high myopia, astigmatism, as well as the longer AL compared with non-Chinese adults in Singapore.

  4. Some notes on critical appraisal of prevalence studies: Comment on: "The development of a critical appraisal tool for use in systematic reviews addressing questions of prevalence".

    2014-10-01

    Decisions in healthcare should be based on information obtained according to the principles of Evidence-Based Medicine (EBM). An increasing number of systematic reviews are published which summarize the results of prevalence studies. Interpretation of the results of these reviews should be accompanied by an appraisal of the methodological quality of the included data and studies. The critical appraisal tool for prevalence studies developed and tested by Munn et al. comprises 10 items and aims at targeting all kinds of prevalence studies. This comment discusses the pros and cons of different designs of quality appraisal tools and highlights their importance for systematic reviews of prevalence studies. Beyond piloting, which has been performed in the study by Munn et al., it is suggested here that the validity of the tool should be tested, including reproducibility and inter-rater reliability. It is concluded that studies as the one by Munn et al. will help to establish a critical understanding of methodological quality and will support the use of systematic reviews of non-intervention studies for health policy making.

    Empirical studies examining perceived ethnic discrimination in Latinos of diverse background groups are limited. This study examined prevalence and correlates of discrimination in a diverse sample of U.S. Latinos (N=5,291) from the multi-site Hispanic Community Health Study/Study of Latinos (HCHS/SOL) and HCHS/SOL Sociocultural Ancillary Study. The sample permitted an examination of differences across seven groups (Central American, Cuban, Dominican, Mexican, Puerto Rican, South American, and Other/Multiple Background). Most participants (79.5%) reported lifetime discrimination exposure and prevalence rates ranged from 64.9% to 98% across groups. Structural Equation Models (SEM) indicated that after adjusting for sociodemographic covariates most group differences in reports of discrimination were eliminated. However, Cubans reported the lowest levels of discrimination, overall among all groups. Furthermore, regional effects were more important than group effects. Participants from Chicago reported the highest levels of discrimination in comparison to other regions. Group differences among Latinos appear to be primarily a function of sociodemographic differences in education, income, and acculturation. In addition, differences in exposure to discrimination may be tied to variables associated with both immigration patterns and integration to U.S. culture. Results highlight the importance of considering historical context and the intersection of discrimination and immigration when evaluating the mental health of Latinos.

    Disease (BOLD foi desenvolvida para que a prevalência da DPOC possa ser avaliada com metodologia normalizada. O objetivo deste estudo foi estimar a prevalência da DPOC em adultos com 40 ou mais anos numa população alvo de 2 700 000 habitantes na região de Lisboa, de acordo com o protocolo BOLD. Métodos: A amostra foi estratificada de forma aleatória multifaseada selecionando-se 12 freguesias. O inquérito compreendia um questionário com informação sobre fatores de risco para a DPOC e doença respiratória autoreportada; adicionalmente, foi efetuada espirometria com prova de broncodilatação. Resultados: Foram incluídos 710 participantes com questionário e espirometria aceitáveis. A prevalência estimada da DPOC na população no estádio GOLD I+ foi de 14,2% (IC 95%: 11,1; 18,1 e de 7,3% no estádio ii+ (IC 95%: 4,7; 11,3. A prevalência não ajustada foi de 20,2% (IC 95%: 17,4; 23,3 no estádio i+ e de 9,5% (IC 95%: 7,6; 11,9 no estádio ii+. A prevalência da DPOC no estádio GOLD II+ aumentou com a idade, sendo mais elevada no sexo masculino. A prevalência estimada da DPOC no estádio GOLD I+ foi de 9,2% (IC 95%: 5,9; 14,0 nos não fumadores versus 27,4% (IC 95%: 18,5; 38,5 nos fumadores com carga tabágica de ≥ 20 Unidades Maço Ano. Detetou-se uma fraca concordância entre a referência a diagnóstico médico prévio e o diagnóstico espirométrico, com 86,8% de subdiagnósticos. Conclusões: O achado de uma prevalência estimada da DPOC de 14,2% sugere que esta é uma doença comum na região de Lisboa, contudo com uma elevada proporção de subdiagnósticos. Estes dados apontam para a necessidade de aumentar o grau de conhecimento dos profissionais de saúde sobre a DPOC, bem como a necessidade de maior utilização da espirometria nos cuidados de saúde primários.

    Full Text Available Background. Atopic allergy is effected by a number of environmental exposures, such as dry air and time spent outdoors, but there are few estimates of the prevalence in populations from sub-arctic areas. Objective. To determine the prevalence and severity of symptoms of food, inhalation and skin-related allergens and coeliac disease (CD in the sub-arctic region of Sweden. To study the correlation between self-reported allergy and allergy test results. To estimate the heritability of these estimates. Study design. The study was conducted in Karesuando and Soppero in Northern Sweden as part of the Northern Sweden Population Health Study (n=1,068. We used a questionnaire for self-reported allergy and CD status and measured inhalation-related allergens using Phadiatop, food-related allergens using the F×5 assay and IgA and IgG antibodies against tissue transglutaminase (anti-tTG to indicate prevalence of CD. Results. The prevalence of self-reported allergy was very high, with 42.3% reporting mild to severe allergy. Inhalation-related allergy was reported in 26.7%, food-related allergy in 24.9% and skin-related allergy in 2.4% of the participants. Of inhalation-related allergy, 11.0% reported reactions against fur and 14.6% against pollen/grass. Among food-related reactions, 14.9% reported milk (protein and lactose as the cause. The IgE measurements showed that 18.4% had elevated values for inhalation allergens and 11.7% for food allergens. Self-reported allergies and symptoms were positively correlated (p<0.01 with age- and sex-corrected inhalation allergens. Allergy prevalence was inversely correlated with age and number of hours spent outdoors. High levels of IgA and IgG anti-tTG antibodies, CD-related allergens, were found in 1.4 and 0.6% of participants, respectively. All allergens were found to be significantly (p<3e–10 heritable, with estimated heritabilities ranging from 0.34 (F×5 to 0.65 (IgA. Conclusions. Self-reported allergy

    The exact antenatal prevalence of congenital anomalies in Saudi society is unknown. Early antenatal diagnosis of congenital anomalies is crucial for early counseling, intervention and possible fetal therapy. The objective of this study was to evaluate the antenatal frequency of major congenital anomalies and malformations patterns in our hospital population and to evaluate the outcome and perinatal mortality rates for major congenital anomalies. This was a prospective study of the antenatal diagnosis of major fetal congenital anomalies conducted in the ultrasound Department of the Women's Specialized Hospital at King Fahd Medical City from for 7762 patients and 5379 babies delivered in our institution. We diagnosed 217 cases of fetal anomalies. The antenatal prevalence of congenital anomalies was 27.96 per 1000. The median maternal age at diagnosis was 27.5 years. Te median gestational age at diagnosis was 31 weeks. Genitourinary and cranial anomalies were the commonest; for 186 patients delivered in our institution, the birth prevalence was 34.57 per 1000 births. The median gestational age at delivery was 38 weeks. The perinatal mortality arte was 34.9% (65/186), including all cases of intrauterine fetal and neonatal deaths. The prevalence of major congenital anomalies in our population appears to be similar to international figures. Major congenital anomalies are a major cause of perinatal mortality. (author)

It is important to appreciate factors associated with the disease so that a holistic approach can be taken in tackling the rising burden. The objective of this study was to determine the prevalence of overweight and obesity and the factors independently associated with obesity in an urban Nigerian population. Methods A cross-sectional study of 300 healthy adult subjects was conducted in the urban city of Katsina, northern Nigeria. Relevant sociodemographic and clinical information were obtained. Screening for obesity was done using the Body Mass Index while relevant laboratory investigations were conducted. Univariate and multivariate logistic regression analyses were performed to determine the predictors of obesity. Results Overweight and obesity was found in 53.3% and 21.0% respectively with a significantly higher prevalence in females compared to males (overweight: 62.0% vs 41.9%, p Conclusion There is a high prevalence of obesity in northern Nigeria and women are significantly more affected. The high prevalence is independently associated with female sex, hypercholesterolaemia and hyperuricaemia. Public health education is urgently needed in order to reduce this burden and prevent other non-communicable cardiovascular disorders.

    Salmonella is an important zoonotic pathogen and its prevalence in the chicken meat and eggs acts as a continuous threat to human population. The current studies covering a time period of three years, was carried out to report the isolation of salmonellae from the chicken tissues, eggs and feed ingredient. A total of 1747 random samples from twelve different sources and 56 locations in Islamabad and Northern Punjab area of Pakistan, were screened for isolation studies according to the already published established protocols. The analysis of 1747 random samples comprising of 1069 (61.19%) chicken organs and 678 (38.81%) allied sources including eggs and feed ingredients, showed that a total of 162 (9.27%) were positive for salmonellae. Isolation prevalence in various chicken organs and allied sources was 86 (8.04%) and 76 (11.20%) respectively. The maximum isolation prevalence was recorded in meat meal (19.35%), followed by fish meal (17.54%), hatchery fluff (14.63%), livers (13.17%), poultry litter (10.89%), and eggs (9.64%). The range of Salmonella isolated varied from 19.35% to 4.72% in various organs and allied sources. Our findings highlighted a potential public health hazard and emphasized the significance of continuous surveillance system in the country to understand the ever changing epidemiological pattern of Salmonella serovers. The endemic prevalence of various serovars can cause outbreaks of human salmonellosis due to the consumption of contaminated meat and eggs as has already been reported worldwide.

    A plateau in childhood overweight and obesity has been reported in some developed countries while in almost all developing countries this problem is on the rise. The aim of this paper is to describe the changes in prevalence of overweight and obesity within a cohort of preschool children followed for 3 years, and to estimate and compare the incidences in urban and rural children of Hanoi, Vietnam. A longitudinal study of a cohort of 2677 children aged 3 to 6 years old at the beginning of the study was conducted in urban DodaLab and rural FilaBavi, Hanoi, Vietnam. Overall, 2602 children, 1311 urban and 1291 rural, were followed for 3 years with identical measurements of weight and height in 2013, 2014 and 2016. Standard methods were used to estimate prevalence and incidence as well as confidence intervals. During the three-year follow-up, the overall estimated prevalence of overweight increased from 9.1% to 16.7%. For the urban children, the increase was considerably higher. The overall prevalence of obesity decreased from 6.4% to 4.5% with less decrease in the urban children. In the group of children who were overweight and obese at the start of the study, 41.4% and 30.7%, respectively, remained in the same state three years later. The incidence of overweight and obesity during the three years were 12.4% and 2.7%, respectively. Boys were more likely to develop obesity than girls. Already in preschool age, the prevalence of overweight is high and it continues to increase with age, especially in the urban area. Prevention and intervention programs need to start at early preschool age and actions in urban areas deserve priority.

    Full Text Available Background: Epilepsy is one of the most common chronic neurological disorders. In children, it has long debilitating course and is associated with comorbidities including psychiatric comorbidity. To tackle this burden of comorbidities, we must know the extent of problem. Hence, there is a need for estimation of prevalence of psychiatry disorder in children with epilepsy. Aim: The present study was aimed at measuring the prevalence of various psychiatry disorders among children suffering from epilepsy. Settings and Design: Cross-sectional chart review. Methodology: We reviewed case record files of all patients with a diagnosis of epilepsy in the age group of 9–17 years. Chart review was done for 5 years, May 1, 2007, to April 30, 2012. A total of 718 patients record were included in the study after satisfying inclusion criteria and excluding nonepilepsy diagnosis. Statistical Analysis: Statistics was done using Statistical Package for Social Sciences (SPSS 18.0. Descriptive statistics were used to calculate the result, Chi-square and Mann–Whitney U-test used wherever applicable. Results: The prevalence of childhood psychiatric disorder among children with epilepsy found to be 31.2%. We also found that having a partial component (73.21%, n = 164 in seizure has more chances of psychopathology in comparison to generalized seizure (8.1%, n = 18. Among them, those having a partial component with generalization (66.96%, n = 150 had a greater prevalence of psychopathology. Mental retardation was most common psychiatric disorder among psychopathology followed by manic/depressive illness (unipolar followed by unspecified nonorganic psychosis. Conclusion: From our study, we demonstrate the significant mental health needs of children with epilepsy. The evident high prevalence of psychiatry disorder emphasizes the need for psychopathology assessment and treatment as a part of any comprehensive epilepsy clinic.

    Full Text Available Although adult asthma is attributable to occupational factors, few reports are available on asthma prevalence among health care workers in Japan. The objective of this study was to estimate the prevalence of asthma and wheeze among Japanese nursing professionals. A cross-sectional study was conducted by postal survey using a translated version of the European Community Respiratory Health Survey questionnaire from April to June 2013. The analysis included 4634 nursing professionals (257 men and 4377 women and the overall response rate was 84.8%. The prevalence of current asthma and wheeze were 10.7% (95% confidence interval (CI, 9.9%–11.7% and 15.6% (95% CI, 14.5%–16.6%, respectively. More than one year of work experience as a nursing professional and more than one year of experience with bed-making tasks were associated with odds ratios (ORs of 1.95 (95% CI, 1.12–3.39 and 1.64 (95% CI, 1.15–2.23 for wheeze, respectively. Current smoking was significantly associated with the presence of wheeze, with ORs of 2.27 for men (95% CI, 1.11–4.64 and 2.01 for women (95% CI, 1.54–2.64. Among female nurses, latex allergy was associated with wheeze (OR, 1.87; 95% CI, 1.56–2.23, as was body mass index ≥30 (OR, 2.76; 95% CI, 1.65–4.62. This study has provided the prevalence of asthma and wheeze among Japanese nursing professionals. Employment period, bed-making tasks, latex allergy, obesity, and smoking may be risk factors for prevalent wheeze among nursing professionals.

    Despite indications that there are differences in rates of child maltreatment (CM) cases in the child protection system between urban and rural areas, there are no published studies examining the differences in self-reported CM prevalence and its correlates by urbanicity. The present study aimed to: (1) identify the distribution of self-reported childhood experiences of maltreatment by urbanicity, (2) assess whether differences by urbanicity persist after adjusting for known risk factors, and (3) explore whether the associations between these risk factors and CM are modified by urban-rural designation. Using nationally representative data from waves I and III of the National Longitudinal Study of Adolescent to Adult Health, the prevalence of six maltreatment outcomes was estimated for rural, minor urban, and major urban areas (N = 14,322). Multivariable logistic models were estimated identifying if risk associated with urbanicity persisted after adjusting for other risk factors. Interactions between urbanicity and main effects were explored. Prevalence estimates of any CM, poly-victimization, supervision neglect, and physical abuse were significantly higher in major urban areas. Those from major urban areas were more likely to report any maltreatment and supervision neglect even after adjusting for child and family risk factors. The association between race/ethnicity, welfare receipt, low parental educational attainment, and disability status and CM were modified by urbanicity. Significant differences in the prevalence and correlates of CM exist between urban and rural areas. Future research and policy should use self-reported prevalence, in conjunction with official reports, to inform child maltreatment prevention and intervention. Copyright © 2018 Elsevier Ltd.

    Full Text Available Objective The present study was undertaken to determine the prevalence of periodontal diseases among adults visiting the dental department of a hospital based in Jorpati. Methods Four hundred and seventeen patients were randomly taken from a dental hospital situated in Jorpati during the time period of March 2013 to August 2013. All patients visiting the dental department who fulfilled the inclusion criteria were included in the study. The data included patients overall information along with their chief complaint, gingival bleeding on probing (BOP, probing depth (PD, frequency of brushing, adverse habits and the diagnosis of the patients examined. Results We found that 52.5% suffered from gingivitis and 47.5% suffered from periodontitis. Also 28.3% suffered from localized and 18% suffered from generalized form of periodontitis. There was no statistically significant difference in the gender when the prevalence of periodontal disease was compared. 51.4% of male and 44.4% of female was seen to be affected with periodontitis. Also habits like smoking and intake of smokeless tobacco was seen to be associated with periodontitis. Regarding the age group more number of patients in the age group of >50 years were seen to be suffering from periodontitis (84.3% as compared to age group of <35 years (25.9%. Conclusion There is high prevalence of periodontitis and gingivitis in the studied population. Periodontitis was seen to be more prevalent as age advanced which can be attributed mainly to untreated gingivitis. However, no significant difference was seen in the prevalence of periodontitis with respect to gender.

    Vitreo-retinal diseases are among the leading causes of visual impairment and blindness worldwide. This study reports the prevalence and pattern of vitreo-retinal diseases in the Bhaktapur Glaucoma Study (BGS), a population based study conducted in Nepal. BGS was a population based cross-sectional study involving 4800 subjects aged 40 years and over from Bhaktapur district. Subjects were selected using a cluster sampling methodology and a door-to-door enumeration. All subjects underwent a detailed ocular examination at the base hospital which included log MAR visual acuity, refraction, applanation tonometry and a dilated fundus examination. Fundus photography, optical coherence tomography and fundus fluorescein angiography were performed where indicated. Complete data was available for 3966 (82.62%) out of the total of 4800 enumerated subjects. The mean age was 55.08 years (SD 11.51). The overall prevalence of vitreo-retinal disorders was 5.35% (95% CI, 4.67 - 6.09). Increasing age was associated with a higher prevalence of vitreo-retinal disorders (P < 0.001). The prevalence of diabetes mellitus was 7.69% (95% CI, 6.88 - 8.56). Age-related macular degeneration (AMD) was the most common vitreo-retinal disorder with a prevalence of 1.50% (95% CI, 1.15 - 1.94), increasing significantly with age. The prevalence of diabetic retinopathy among the study population was 0.78% (95% CI, 0.53 - 1.11) and among the diabetic population 10.16% (95% CI, 7.01 - 14.12). The population prevalence of other retinal disorders were hypertensive retinopathy 0.88%, macular scar 0.37%, retinal vein occlusion 0.50%, macular hole 0.20%, retinitis pigmentosa 0.12%. and retinal detachment 0.10%.The prevalence of low vision and blindness due to vitreo-retinal disorders was 1.53% (95% CI, 1.18 - 1.97) and 0.65% (95% CI, 0.43 - 0.96), respectively. The prevalence of low vision and blindness was 28.77% (95% CI, 22.78-35.37) and 12.26% (95% CI, 8.17-17.45), respectively among cases with vitreo

    The main purpose of the study was to estimate prevalence of subjects with hypertriglyceridemia (HTG) in Russia. Secondary objectives were to explore HTG prevalence by levels, age and sex, and to assess correlation between glycated hemoglobin (HbA1C) and triglyceride (TG) level. Additionally, we analyzed geographical differences in HTG prevalence in regions of Russia. This was a cross-sectional, retrospective, observational study using database of results of lipid profile determination in 357,072 subjects from 254 Russian cities during the 3-year period from 2011 to 2013. Altogether, 29.2% (95% confidence interval [CI] 29.1-29.4%) of Russian individuals had HTG (serum TG more or equal 1.7 mmol/L). The percentage of patients with very high (TG more or equal 5.6 mmol/L) and severe HTG (TG more or equal 10.0mmol/L) was low (0.01% and 0.011%, respectively). At the same time, the portion of subjects with mixed hyperlipidemia (total cholesterol [TC] more or equal 5.2mmol/L, low-density lipoprotein cholesterol [LDL-C] more or equal 3.4 mmol/L, TG more or equal 1.7 mmol/L) was 19% of the study population. Men had 1.25 (95% CI, 1.24-1.26) times higher risk of HTG than women. Prevalence of HTG increased with age: in women TG level was maximal in the age group 60-69 years (34%), whereas in men TG level was maximal in the age group 40-49 years (43%). Prevalence of HTG increased from 2011 to 2013 from 28 to 30% (p<0.0001). Risk of HTG was 1.69 times greater when high HbA1C more or equal 6.5% was present, and vice versa, risk of HbA1C more or equal 6.5% was 2.04 times higher in individuals with HTG. Distribution of HTG and dyslipidemia by regions of Russia had large variability being higher in the south and lower in the northern regions of European part of Russia. Almost a third of Russian population has HTG. Men have higher risk of HTG than women. Prevalence of HTG increases with age and reaches its peak in age groups 60-69 years in (women) and 40-49 years (men). There is a

    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.

    To study the distribution of refractive errors among adults of European descent. Population-based eye study in Germany with 15010 participants aged 35-74 years. The study participants underwent a detailed ophthalmic examination according to a standardised protocol. Refractive error was determined by an automatic refraction device (Humphrey HARK 599) without cycloplegia. Definitions for the analysis were myopia +0.5 D, astigmatism >0.5 cylinder D and anisometropia >1.0 D difference in the spherical equivalent between the eyes. Exclusion criterion was previous cataract or refractive surgery. 13959 subjects were eligible. Refractive errors ranged from -21.5 to +13.88 D. Myopia was present in 35.1% of this study sample, hyperopia in 31.8%, astigmatism in 32.3% and anisometropia in 13.5%. The prevalence of myopia decreased, while the prevalence of hyperopia, astigmatism and anisometropia increased with age. 3.5% of the study sample had no refractive correction for their ametropia. Refractive errors affect the majority of the population. The Gutenberg Health Study sample contains more myopes than other study cohorts in adult populations. Our findings do not support the hypothesis of a generally lower prevalence of myopia among adults in Europe as compared with East Asia.

    Full Text Available Abstract Background Measuring recurrent infections such as diarrhoea or respiratory infections in epidemiological studies is a methodological challenge. Problems in measuring the incidence of recurrent infections include the episode definition, recall error, and the logistics of close follow up. Longitudinal prevalence (LP, the proportion-of-time-ill estimated by repeated prevalence measurements, is an alternative measure to incidence of recurrent infections. In contrast to incidence which usually requires continuous sampling, LP can be measured at intervals. This study explored how many more participants are needed for infrequent sampling to achieve the same study power as frequent sampling. Methods We developed a set of four empirical simulation models representing low and high risk settings with short or long episode durations. The model was used to evaluate different sampling strategies with different assumptions on recall period and recall error. Results The model identified three major factors that influence sampling strategies: (1 the clustering of episodes in individuals; (2 the duration of episodes; (3 the positive correlation between an individual's disease incidence and episode duration. Intermittent sampling (e.g. 12 times per year often requires only a slightly larger sample size compared to continuous sampling, especially in cluster-randomized trials. The collection of period prevalence data can lead to highly biased effect estimates if the exposure variable is associated with episode duration. To maximize study power, recall periods of 3 to 7 days may be preferable over shorter periods, even if this leads to inaccuracy in the prevalence estimates. Conclusion Choosing the optimal approach to measure recurrent infections in epidemiological studies depends on the setting, the study objectives, study design and budget constraints. Sampling at intervals can contribute to making epidemiological studies and trials more efficient, valid

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

    Refractive errors are a common eye problem. Considering the low number of population-based studies in Iran in this regard, we decided to determine the prevalence rates of myopia and hyperopia in a population in Mashhad, Iran. Cross-sectional population-based study. Random cluster sampling. Of 4453 selected individuals from the urban population of Mashhad, 70.4% participated. Refractive error was determined using manifest (age > 15 years) and cycloplegic refraction (age ≤ 15 years). Myopia was defined as a spherical equivalent of -0.5 diopter or worse. An spherical equivalent of +0.5 diopter or worse for non-cycloplegic refraction and an spherical equivalent of +2 diopter or worse for cycloplegic refraction was used to define hyperopia. Prevalence of refractive errors. The prevalence of myopia and hyperopia in individuals ≤ 15 years old was 3.64% (95% CI: 2.19-5.09) and 27.4% (95% CI: 23.72-31.09), respectively. The same measurements for subjects > 15 years of age was 22.36% (95% CI: 20.06-24.66) and 34.21% (95% CI: 31.57-36.85), respectively. Myopia was found to increase with age in individuals ≤ 15 years and decrease with age in individuals > 15 years of age. The rate of hyperopia showed a significant increase with age in individuals > 15 years. The prevalence of astigmatism was 25.64% (95% CI: 23.76-27.51). In children and the elderly, hyperopia is the most prevalent refractive error. After hyperopia, astigmatism is also of importance in older ages. Age is the most important demographic factor associated with different types of refractive errors. © 2011 The Authors.

    Full Text Available Background. Previous observations found a high prevalence of obstructive sleep apnea (OSA in the hemodialysis population, but the best diagnostic approach remains undefined. We assessed OSA prevalence and performance of available screening tools to propose a specific diagnostic algorithm. Methods. 104 patients from 6 Swiss hemodialysis centers underwent polygraphy and completed 3 OSA screening scores: STOP-BANG, Berlin’s Questionnaire, and Adjusted Neck Circumference. The OSA predictors were identified on a derivation population and used to develop the diagnostic algorithm, which was validated on an independent population. Results. We found 56% OSA prevalence (AHI ≥ 15/h, which was largely underdiagnosed. Screening scores showed poor performance for OSA screening (ROC areas 0.538 [SE 0.093] to 0.655 [SE 0.083]. Age, neck circumference, and time on renal replacement therapy were the best predictors of OSA and were used to develop a screening algorithm, with higher discriminatory performance than classical screening tools (ROC area 0.831 [0.066]. Conclusions. Our study confirms the high OSA prevalence and highlights the low diagnosis rate of this treatable cardiovascular risk factor in the hemodialysis population. Considering the poor performance of OSA screening tools, we propose and validate a specific algorithm to identify hemodialysis patients at risk for OSA for whom further sleep investigations should be considered.

In adults (aged 20-79 years), recruitment was stratified by age, sex, geographic region and settlement type to obtain a representative sample. Recruitment was in public areas with high numbers of people. T2DM was diagnosed by glycated haemoglobin A1c (HbA1c) levels (diabetes: HbA1c ≥6.5% [≥48mmol/mol]; pre-diabetes: HbA1c ≥5.7 to diabetic. T2DM prevalence increased with age (up to 70 years) and was higher among females than males (6.1% vs. 4.7%, pdiabetes and T2DM tended to increase with increasing body mass index. T2DM prevalence was higher in rural versus urban populations (6.7% vs. 5.0%, pdiabetes, T2DM prevalence was 5.4%, and 54% of subjects with diabetes were previously undiagnosed. These results may help to develop a new T2DM predictive, preventative and management programme in Russia. Copyright © 2016 The Authors. Published by Elsevier Ireland Ltd.. All rights reserved.

    Celiac disease may emerge at any age, but little is known of its appearance in elderly people. We evaluated the prevalence of the condition in individuals over 55 years of age, and determined the incidence of biopsy-proven celiac disease (CDb) and celiac disease including seropositive subjects for anti-tissue transglutaminase antibodies (CDb+s). The study based on prevalence figures in 2815 randomly selected subjects who had undergone a clinical examination and serologic screening for celiac disease in 2002. A second screening in the same population was carried out in 2005, comprising now 2216 individuals. Positive tissue transglutaminase antibodies were confirmed with small bowel biopsy. Within three years the prevalence of CDb increased from 2.13 to 2.34%, and that of CDb+s from 2.45 to 2.70%. Five new cases were found among patients previously seronegative; two had minor abdominal symptoms and three were asymptomatic. The incidence of celiac disease in 2002-2005 was 0.23%, giving an annual incidence of 0.08% in this population. The prevalence of celiac disease was high in elderly people, but the symptoms were subtle. Repeated screening detected five biopsy-proven cases in three years, indicating that the disorder may develop even in the elderly. Increased alertness to the disorder is therefore warranted.

    Giardia has a wide range of host species and is a common cause of diarrhoeal disease in humans and animals. Companion animals are able to transmit a range of zoonotic diseases to their owners including giardiasis, but the size of this risk is not well known. The aim of this study was to analyse giardiasis prevalence rates in dogs and cats worldwide using a systematic search approach. Meta-analysis enabled to describe associations between Giardia prevalence and various confounding factors. Pooled prevalence rates were 15.2% (95% CI 13.8-16.7%) for dogs and 12% (95% CI 9.2-15.3%) for cats. However, there was very high heterogeneity between studies. Meta-regression showed that the diagnostic method used had a major impact on reported prevalence with studies using ELISA, IFA and PCR reporting prevalence rates between 2.6 and 3.7 times greater than studies using microscopy. Conditional negative binomial regression found that symptomatic animals had higher prevalence rates ratios (PRR) than asymptomatic animals 1.61 (95% CI 1.33-1.94) in dogs and 1.94 (95% CI 1.47-2.56) in cats. Giardia was much more prevalent in young animals. For cats >6 months, PRR=0.47 (0.42-0.53) and in dogs of the same age group PRR=0.36 (0.32-0.41). Additionally, dogs kept as pets were less likely to be positive (PRR=0.56 (0.41-0.77)) but any difference in cats was not significant. Faecal excretion of Giardia is common in dogs and slightly less so in cats. However, the exact rates depend on the diagnostic method used, the age and origin of the animal. What risk such endemic colonisation poses to human health is still unclear as it will depend not only on prevalence rates but also on what assemblages are excreted and how people interact with their pets.

  20. Is the prevalence of overactive bladder overestimated? A population-based study in Finland.

    Directory of Open Access Journals (Sweden)

    Kari A O Tikkinen

    Full Text Available BACKGROUND: In earlier studies, one in six adults had overactive bladder which may impair quality of life. However, earlier studies have either not been population-based or have suffered from methodological limitations. Our aim was to assess the prevalence of overactive bladder symptoms, based on a representative study population and using consistent definitions and exclusions. METHODOLOGY/PRINCIPAL FINDINGS: The aim of the study was to assess the age-standardized prevalence of overactive bladder defined as urinary urgency, with or without urgency incontinence, usually with urinary frequency and nocturia in the absence of urinary tract infection or other obvious pathology. In 2003-2004, a questionnaire was mailed to 6,000 randomly selected Finns aged 18-79 years who were identified from the Finnish Population Register Centre. Information on voiding symptoms was collected using the validated Danish Prostatic Symptom Score, with additional frequency and nocturia questions. Corrected prevalence was calculated with adjustment for selection bias due to non-response. The questionnaire also elicited co-morbidity and socio-demographic information. Of the 6,000 subjects, 62.4% participated. The prevalence of overactive bladder was 6.5% (95% CI, 5.5% to 7.6% for men and 9.3% (CI, 7.9% to 10.6% for women. Exclusion of men with benign prostatic hyperplasia reduced prevalence among men by approximately one percentage point (to 5.6% [CI, 4.5% to 6.6%]. Among subjects with overactive bladder, urgency incontinence, frequency, and nocturia were reported by 11%, 23%, and 56% of men and 27%, 38%, and 40% of women, respectively. However, only 31% of men and 35% of women with frequency, and 31% of subjects of both sexes with nocturia reported overactive bladder. CONCLUSIONS/SIGNIFICANCE: Our results indicate a prevalence of overactive bladder as low as 8% suggesting that, in previous studies, occurrence has been overestimated due to vague criteria and selected study

    Background Dyspnea (breathing discomfort) can be as powerfully aversive as pain, yet is not routinely assessed and documented in the clinical environment. Routine identification and documentation of dyspnea is the first step to improved symptom management and it may also identify patients at risk of negative clinical outcomes. Objective To estimate the prevalence of dyspnea and of dyspnea-associated risk among hospitalized patients. Design Two pilot prospective cohort studies. Setting Single academic medical center. Patients Consecutive patients admitted to four inpatient units: cardiology, hematology/oncology, medicine, and bariatric surgery. Measurements In Study 1, nurses documented current and recent patient-reported dyspnea at the time of the Initial Patient Assessment in 581 inpatients. In Study 2, nurses documented current dyspnea at least once every nursing shift in 367 patients. We describe the prevalence of burdensome dyspnea, and compare it to pain. We also compared dyspnea ratings with a composite of adverse outcomes: 1) receipt of care from the hospital’s rapid response system, 2) transfer to the intensive care unit, or 3) death in hospital. We defined burdensome dyspnea as a rating of 4 or more on a 10-point scale. Results Prevalence of burdensome current dyspnea upon admission (Study 1) was 13% (77 of 581, 95% CI 11%-16%). Prevalence of burdensome dyspnea at some time during the hospitalization (Study 2) was 16% (57 of 367, 95% CI 12%-20%). Dyspnea was associated with higher odds of a negative outcome. Conclusions In two pilot studies, we identified a significant symptom burden of dyspnea in hospitalized patients. Patients reporting dyspnea may benefit from a more careful focus on symptom management and may represent a population at greater risk for negative outcomes. PMID:27070144

    To describe the methodology of the EPISER 2016 (study of the prevalence of rheumatic diseases in adult population in Spain), as well its strengths and limitations. The aim of this study is to estimate the prevalence of rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), systemic lupus erythematosus (SLE), Sjögren's syndrome (SS), osteoarthritis (knee, hip, hands, and cervical and lumbar spine), fibromyalgia, gout and clinical osteoporotic fracture. Population-based, multicenter, cross-sectional study, with the participation of 45 municipalities in the 17 Spanish autonomous communities. The reference population will consist of adults aged 20 years and over residing in Spain. A computer-assisted telephone interview (CATI) system will be used for data collection. Diagnostic suspicions and diagnoses received by the participants will be studied by rheumatologists in the referral hospitals in the selected municipalities. the prevalence of the rheumatic diseases will be calculated using estimators and their 95% confidence intervals. Weights will be calculated in each of the sampling stages in accordance with the probability of selection. The distribution of the population in Spain will be obtained from the Spanish Statistics Institute. Sociodemographic and lifestyle changes over the last 16 years justify EPISER 2016. This study will provide current data about the prevalences of RA, AS, PsA, SLE, SS, osteoarthritis, fibromyalgia, gout and clinical osteoporotic fracture. The results will allow comparisons with studies from other countries and EPISER 2000.

    Flat foot (pes planus) is a commonly observed disorder in clinical practice. The height of Medial Longitudinal Arch (MLA) determines the degree of pes planus. Majority of the previous studies on prevalence of flexible flat foot were done among children. The present study was undertaken to determine the prevalence of flexible flat foot among 18-21-year-old Indian adults using Navicular Drop Test (NDT) which is regarded as reliable and valid method to characterise MLA. The present study was a cross-sectional study in which Brody's Navicular Drop Test was performed in five hundred healthy subjects (250 males and 250 females) aged 18-21-year-old. Navicular Drop (ND) of ≥ 10 mm was regarded as flexible flat foot. Statistical analysis was done using SPSS version 23.0. The prevalence of flexible flat foot was 13.6% (for males-12.8%; for females-14.4%). The median with Inter Quartile Range (IQR) for ND among males was 6 mm (4-8) and 6 mm (4-9) for right and left foot respectively. The median with IQR for ND among females was 6mm (4-10) and 7mm (3-8) for right & left respectively. The correlation of Right Side Navicular Drop (RND) with height and weight was significant, but insignificant correlation was found between RND and BMI. The correlation of Left Side Navicular Drop (LND) with height, weight and BMI of individuals was statistically not significant. The difference between the ND of males and female group was statistically not significant. The present study quantified the prevalence of flexible flat foot and gender wise normative values of ND among 18-21-year-old Indian adults. The information obtained by this study will be useful in the field of orthopaedics.

    Global and regional studies on the prevalence of food allergies are plagued by inconsistent methodologies, variations in interpretation of results, and non-standardized study design. Hence, it becomes difficult to compare the prevalence of food allergies in different communities. This information would be useful in providing critical data that will enhance research to elucidate the nature of food allergies, and the role of gene-environment interactions in the sensitization of children and adults to foods. Testing methodologies range from questionnaires to objective in vitro and in vivo testing, to the gold standard, double-blind placebo-controlled food challenge (DBPCFC). Although considered the most accurate and reliable method in detecting the prevalence of food allergy, DBPCFC is not always practical in epidemiological studies of food allergy. On the other hand, multiple logistic regression studies have been done to determine predictability of the outcome of food challenges, and it appears that skin prick testing and in vitro-specific serum IgE are the best predictors. Future studies directed towards confirming the validity of these methods as well as developing algorithms to predict the food challenge outcomes are required, as they may someday become accessory tools to complement DBPCFC.

    Mental disorders often have onset early in life, contribute substantially to the global disease burden, and may interfere with young people's ability to complete age-relevant tasks in important developmental periods. However, knowledge about prevalence and course of mental disorders in young adulthood is sparse. The aim of the current study was to estimate prevalence and stability of mental disorders from the twenties to the thirties/forties. DSM-IV mental disorders were assessed with the Composite International Diagnostic Interview in two waves (1999-2004 and 2010-2011) in 1623 young adult Norwegian twins (63.2% women, aged 19-29 years in wave 1). In wave 1, the 12-month prevalence of any mental disorder among people in the twenties was 19.8% (men) and 32.4% (women), anxiety disorders: 9.6% (men) and 26.7% (women), anxiety disorders excluding specific phobias: 2.5% (men) and 6.9% (women), major depressive disorder (MDD): 4.4% (men) and 7.2% (women), and alcohol use disorder (AUD): 8.7% (men) and 4.4% (women). The prevalence of any mental disorder decreased from the twenties to the thirties/forties. This was due to a decrease in AUD and specific phobias. Anxiety disorders in the twenties predicted anxiety disorders and MDD ten years later, even when controlling for the association between these disorders in the twenties. MDD in the twenties predicted MDD ten years later. At both ages, two-week and 12-month prevalence estimates differed markedly for MDD - indicating an episodic course. Common mental disorders are highly prevalent among young adults in the twenties, and somewhat less prevalent in the thirties/forties. Those who suffer from one mental disorder in the twenties are at considerably increased risk for suffering from a disorder ten years later as well. This may have significant implications for young people's ability to attain education, establish a family, and participate in occupational life.

    Nowadays, coal workers' pneumoconiosis (CWP) is still believed to be the main occupational disease in China. However, information on the exact prevalence of the disease is not available. Therefore, the aims of our investigation were to provide the missing information in China by conducting a systematic evaluation of published data from 2001 to 2011 and to compare the prevalence of CWP with those in other countries. Published reports about the prevalence of CWP were searched from PudMed(English language databases), Foreign Medical Journal Full-Text Service Database (FMJS, English language databases), Chinese Journal Full-Text Database (CJFD, Chinese language databases), Chongqing VIP Chinese Science and Technology Journals Database (VIP, Chinese language databases), Chinese Biomedical Literature Database (CBM, Chinese language databases) and Chinese Medical Association Journals Database (CMAJ, Chinese language databases). The quality of identified reports was strictly evaluated using predetermined inclusion and exclusion criteria. Based on these criteria, 11 reports were selected. Then, the content of these reports were reviewed and the needed information was extracted. Meta-analysis was performed on the extracted data. The R2.15.1 software was applied for statistical analysis. The total populations from these reports were 173,646 and 10,821 for dust-exposed coal workers and patients with CWP, respectively. The pooled prevalence of CWP was 6.02% (95% CI: 3.43-9.26%) and the pooled rate of CWP patients combined with tuberculosis was 10.82% (95% CI: 8.26-13.66%). The prevalence was analyzed according to the geographic areas of the study, years of the investigation, duration of dust exposure, coal rank, stages of CWP, types of work and coal-mining categories, etc. Among them, the prevalence of CWP in locally owned mines (9.86%; 95% CI: 1.25-25.17%) was significantly higher than that of state-owned mines (4.83%; 95% CI: 2.35-8.13%) (P0.05). It was concluded that the

    Background Stroke is a growing public health concern in low- and middle- income countries. Improved knowledge about the association between socioeconomic status and stroke in these countries would enable the development of effective stroke prevention and management strategies. This study presents the association between socioeconomic status and the prevalence of stroke in Morocco, a lower middle-income country. Methods Data on the prevalence of stroke and stroke-related risk factors were collected during a large population-based survey. The diagnosis of stroke in surviving patients was confirmed by neurologists while health, demographic, and socioeconomic characteristics of households were collected using structured questionnaires. We used Multiple Correspondence Analysis to develop a wealth index based on characteristics of the household dwelling as well as ownership of selected assets. We used logistic regressions controlling for multiple variables to assess the statistical association between socioeconomic status and stroke. Findings Our results showed a significant association between household socioeconomic status and the prevalence of stroke. This relationship was non-linear, with individuals from both the poorest (mainly rural) and richest (mainly urban) households having a lower prevalence of stroke as compared to individuals with medium wealth level. The latter belonged mainly to urban households with a lower socioeconomic status. When taking into account the urban population only, we observed that a third of poorest households experienced a significantly higher prevalence of stroke compared to the richest third (OR = 2.06; CI 95%: 1.09; 3.89). Conclusion We conclude that individuals from the most deprived urban households bear a higher risk of stroke than the rest of the population in Morocco. This result can be explained to a certain extent by the higher presence of behavioral risk factors in this specific category of the population, which leads in

    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.

    The population of India is extremely diverse comprising of more than 3,000 ethnic groups who still follow endogamy. Haemoglobinopathies are the commonest hereditary disorders in India and pose a major health problem. The data on the prevalence of β-thalassemias and other haemoglobinopathies in different caste/ethnic groups of India is scarce. Therefore the present multicentre study was undertaken in six cities of six states of India (Maharashtra, Gujarat, West Bengal, Assam, Karnataka and Punjab) to determine the prevalence of haemoglobinopathies in different caste/ethnic groups using uniform methodology. Fifty-six thousand seven hundred eighty individuals (college students and pregnant women) from different caste/ethnic groups were screened. RBC indices were measured on an automated haematology counter while the percentage of HbA(2), HbF and other abnormal Hb variants were estimated by HPLC on the Variant Hemoglobin Testing System. The overall prevalence of β-thalassemia trait was 2.78 % and varied from 1.48 to 3.64 % in different states, while the prevalence of β-thalassemia trait in 59 ethnic groups varied from 0 to 9.3 %. HbE trait was mainly seen in Dibrugarh in Assam (23.9 %) and Kolkata in West Bengal (3.92 %). In six ethnic groups from Assam, the prevalence of HbE trait varied from 41.1 to 66.7 %. Few subjects with δβ-thalassemia, HPFH, HbS trait, HbD trait, HbE homozygous and HbE β-thalassemia as well as HbS homozygous and HbS-β-thalassemia (India.

    Full Text Available Background: Within the last 20 years, the prevalence of gestational diabetes mellitus (GDM has been reported to be increasing worldwide in correlation with ethnic and geographic variations. The actual prevalence of GDM throughout all of Greenland remains unknown. Objective: The aim of this study was to estimate the prevalence of GDM among Greenlanders and non-Greenlanders living in Greenland and to estimate the efficacy of testing for GDM. Design: This study was performed as an observational, cross-sectional study including all women with permanent address in Greenland who had given birth to a singleton during 2014. The prevalence of GDM was calculated as the proportion of all pregnant women tested with a 75-g 2-h glucose tolerance test who had a 2-h capillary whole-blood glucose value of 8.5 mmol/l or above. Testing efficacy was calculated as the proportion of women who fulfilled the testing criteria who were actually tested in Greenland in 2014. Results: A total of 794 women (727 Greenlanders and 67 non-Greenlanders were included in the study. The prevalence of GDM among tested women was 3.3% (confidence interval, CI: 0.9–5.6 among Greenlanders and 12.5% (CI: 0–25.7 among non-Greenlanders, corresponding, respectively, to 1.0% (CI: 0.3–1.3 and 4.5% (CI: 0–9.4 of all singleton pregnancies in Greenland in 2014. The overall testing efficacy was 69.0% among all eligible residents of Greenland and 85.1% among eligible residents in the capital city, Nuuk. Conclusion: In conclusion, the prevalence of GDM seems quite low in Greenland. Although diagnostic testing activity has improved within the last 6 years, still around one-third of all pregnant women in all Greenland fulfilling the testing criteria were not tested. Universal testing for GDM may be needed to improve testing of GDM in Greenland.

    Background The Australian Defence Force (ADF) Mental Health Prevalence and Wellbeing Study (MHPWS) is the first study of mental disorder prevalence in an entire military population. Objective The MHPWS aims to establish mental disorder prevalence, refine current ADF mental health screening methods, and identify specific occupational factors that influence mental health. This paper describes the design, sampling strategies, and methodology used in this study. Method At Phase 1, approximately half of all regular Navy, Army, and Air Force personnel (n=24,481) completed self-report questionnaires. At Phase 2, a stratified sub-sample (n=1,798) completed a structured diagnostic interview to detect mental disorder. Based on data from non-responders, data were weighted to represent the entire ADF population (n=50,049). Results One in five ADF members met criteria for a 12-month mental disorder (22%). The most common disorder category was anxiety disorders (14.8%), followed by affective (9.5%) and alcohol disorders (5.2%). At risk ADF sub-groups were Army personnel, and those in the lower ranks. Deployment status did not have an impact on mental disorder rates. Conclusion This study has important implications for mental health service delivery for Australian and international military personnel as well as contemporary veterans. PMID:25206944

    Full Text Available Background and Aims: Acute neuropathic pain (ANP is an under-recognised and under-diagnosed condition and often difficult to treat. If left untreated, it may further transform into persistent post-operative chronic pain leading to a disability. Aims: This prospective study was undertaken on 300 patients to identify the prevalence of ANP in the post-operative period by using a neuropathic pain detection questionnaire tool. Methods: This is an open-label study in which patients with six different types of cancer surgeries (Thoracic, gastro-intestinal, gynae/urology, bone/soft-tissue, head and neck and breast subgroups-50 each were included for painDETECT questionnaire tool on the 2 nd and 7 th day surgery. Results: This study found a 10% point prevalence of ANP. Analysis showed that 25 patients had ′possible′ ANP, the maximum from urological cancer surgery (6 followed by thoracic surgery (5. Five patients were found to have ′positive′ ANP including 2 groin node dissection, 2 hemipelvectomy and 1 oesophagectomy. Conclusion: Significant relationship between severity of post-operative pain was found with the occurrence of ANP in the post-operative period requiring a special attention to neuropathic pain assessment. Larger studies are required with longer follow-up to identify accurately the true prevalence and causative factors of ANP after surgery.

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

    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.

    Full Text Available Objective: The purpose of the present study was to investigate the prevalence of behavioral disorder among of primary school students in Abhar. Materials & Methods: 600 primary school students (300 boys and 300 girls of public primary schools in Abhar, Iran were used as the sample for this study. Their behavioral disorder scores were obtained by means of Rutter's teachers' questionnaire. Results: Using a cutpoint of 9, the prevalence rate of behavioral disorder was 43.3% among subjects, with boys showing higher rates of behavioral disorder (44.7% than girls (42% but no significant differences were found by gender on rates of behavioral disorders. 6.3 percent of the subjects had severe behavioral disorder. Conclusion: Academic achievement was negatively related to behavioral disorder. Significant differences were found by mothers' education on children’s rates of behavioral disorder. Significant differences were found by fathers' occupation on children’s rates of behavioral disorder.

    Full Text Available Workaholism has become an increasingly popular area for empirical study. However, most studies examining the prevalence of workaholism have used non-representative samples and measures with poorly defined cut-off scores. To overcome these methodological limitations, a nationally representative survey among employees in Norway (N = 1,124 was conducted. Questions relating to gender, age, marital status, caretaker responsibility for children, percentage of full-time equivalent, and educational level were asked. Workaholism was assessed by the use of a psychometrically validated instrument (i.e., Bergen Work Addiction Scale. Personality was assessed using the Mini-International Personality Item Pool. Results showed that the prevalence of workaholism was 8.3% (95% CI  = 6.7-9.9%. An adjusted logistic regression analysis showed that workaholism was negatively related to age and positively related to the personality dimensions agreeableness, neuroticism, and intellect/imagination. Implications for these findings are discussed.

    The prevalence of chronic obstructive pulmonary disease (COPD) has not been studied in Argentina. To determine the prevalence and relevant clinical characteristics of COPD in a representative sample. We performed a cross-sectional study in a population of adults aged ≥ 40 years randomly selected by cluster sampling in 6 urban locations. Subjects answered a structured survey and performed pre- and post-bronchodilator spirometry (PBD). COPD was defined as FEV 1 /FVC ratio 80 years), male gender (OR 1.62; CI 1.31-2), smoking (OR 1.95; CI 1.49-2.54), low socioeconomic status (OR 1.33; CI 1.02-1.73), and previous tuberculosis (OR 3.3; CI 1.43-7.62).

    To examine use of magnetic resonance imaging (MRI) of knees with no radiographic evidence of osteoarthritis to determine the prevalence of structural lesions associated with osteoarthritis and their relation to age, sex, and obesity. Population based observational study. Community cohort in Framingham, MA, United States (Framingham osteoarthritis study). 710 people aged >50 who had no radiographic evidence of knee osteoarthritis (Kellgren-Lawrence grade 0) and who underwent MRI of the knee. Prevalence of MRI findings that are suggestive of knee osteoarthritis (osteophytes, cartilage damage, bone marrow lesions, subchondral cysts, meniscal lesions, synovitis, attrition, and ligamentous lesions) in all participants and after stratification by age, sex, body mass index (BMI), and the presence or absence of knee pain. Pain was assessed by three different questions and also by WOMAC questionnaire. Of the 710 participants, 393 (55%) were women, 660 (93%) were white, and 206 (29%) had knee pain in the past month. The mean age was 62.3 years and mean BMI was 27.9. Prevalence of "any abnormality" was 89% (631/710) overall. Osteophytes were the most common abnormality among all participants (74%, 524/710), followed by cartilage damage (69%, 492/710) and bone marrow lesions (52%, 371/710). The higher the age, the higher the prevalence of all types of abnormalities detectable by MRI. There were no significant differences in the prevalence of any of the features between BMI groups. The prevalence of at least one type of pathology ("any abnormality") was high in both painful (90-97%, depending on pain definition) and painless (86-88%) knees. MRI shows lesions in the tibiofemoral joint in most middle aged and elderly people in whom knee radiographs do not show any features of osteoarthritis, regardless of pain.

    Background There are no existing studies that provide data regarding the epidemiology of, and risk factors for, fecal impaction, either in the general population or in any sub-group of people. Objective Estimate the prevalence of and factors associated with fecal impaction on a representative sample of the institutionalized elderly population. Design Two-phase study. Phase 1: pilot study validating the methodology in which all residents of a single nursing home participated. Phase 2: national multi-center cross-sectional study. Setting 34 randomly selected nursing homes. Measurements The presence of fecal impaction and associated factors were evaluated using three different tools: data collected from medical records; a self-completion questionnaire filled out by the subjects or a proxy; and a rectal examination. Subjects Older subjects living in nursing homes. Results The prevalence of chronic constipation was 70.7% (95%CI: 67.3–74.1%), of which 95.9% of patients were properly diagnosed and 43.1% were properly controlled. The prevalence of FI according to patient history was 47.3% (43.6–51.0%) and 6.6% (4.7–8.5%) according to rectal examination. Controlled constipation (OR: 9.8 [5.2–18.4]) and uncontrolled constipation (OR: 37.21 [19.7–70.1]), the number of medications (OR: 1.2 [1.1–1.3]), reduced functional capacity (OR: 0.98 [0.97–0.99]) and the occasional use of NSAIDs were independent risk factors for fecal impaction. Conclusions Constipation affects more than 70% of people living in nursing homes. Although it is properly diagnosed in more than 95% of cases, the disease is only controlled in less than 50%. Constipation, especially when not controlled, is the most significant risk factor leading to fecal impaction, which is prevalent in almost 50% of this population. PMID:25148393

    Full Text Available Although many epidemiological studies defining child sexual abuse prevalence rates in many countries of the world are now available, Italy presents a lack of data regarding this specific issue. Only recently some attempts to define the epidemiology of this public health problem have been tried. Between 2003 and 2010, the Department of Public Health at University of Milan was in charge of one of the more important study of this kind in Italy, involving almost 3000 students aged 18 attending secondary schools in the City of Milan who filled out an anonymous questionnaire aiming at detecting their previous experiences of sexual victimization during childhood and adolescence. After this first edition, the study was replicated among students attending secondary schools in the city of Varese, in the area of Piedmont and in Basilicata (area of Lauria, using the same investigational model and questionnaire. This paper presents the main data collected through four different epidemiological studies using the same methodology and survey tool. Considering at least one of the five different forms of child sexual abuse surveyed (being exposed to pornography, being touched on private parts, being forced to masturbate an older person, being forced to perform oral sex, or being penetrated, the prevalence rate among our samples ranges between a minimum of 12.5% (Varese and a maximum of 34.1% (Lauria. In Lauria the research reveals a higher prevalence rate of child sexual abuse, especially among the male population, for all typologies of abuse but being touched in their private parts. In all other geographical areas and for all typologies of abuse, there is always a higher prevalence among girls, with the only exception of abuse such as being exposed to pornographic materials.

    Full Text Available Background: Tobacco use is one of the leading causes of preventable deaths in the world. The aim of this study was to determine the prevalence of all common types of tobacco use and identify factors associated with tobacco use among adults in Tehran based on information from the population-based Burden of Obstructive Lung Disease study in Tehran. Materials and Methods: This study had a stratified cluster sampling strategy with proportional allocation within strata. The target population was all noninstitutionalized residents of Tehran over 18 years of age in 2013. A total of 1798 individuals were visited in 22 districts of Tehran; 811 (45.1% men and 987 (54.9% women participated in structured interviews. Results: The estimated prevalence of current cigarette smoking was 10.6% overall, 20.9% in men and 2.2% in women. The prevalence of smoking was the highest among respondents between 45 and 54 years in both males and females. The mean age of initiation of tobacco smoking was 21.04 ± 6.42 years. The mean Fagerström test score was 2.87 ± 2.36 among current smokers. The mean number f cigarettes smoked daily by the participants was 11.39 ± 10.92 cigarettes/day (95% confidence interval = 12.58–10.21 (range 1–60 cigarettes. Conclusions: The 10.6% prevalence of cigarette smoking is alarming in Tehran. We found that male gender, hookah smoking experience, and poor health status were major risk factors in our study population. Hookah smoking can be considered as a reflection of tobacco smoking in the society.

    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.

    Data on multimorbidity among the elderly people in Bangladesh are lacking. This paper reports the prevalence and distribution patterns of multimorbidity among the elderly people in rural Bangladesh. This cross-sectional study was conducted among persons aged > or = 60 years in Matlab, Bangladesh. Information on their demographics and literacy was collected through interview in the home. Information about their assets was obtained from a surveillance database. Physicians conducted clinical examinations at a local health centre. Two physicians diagnosed medical conditions, and two senior geriatricians then evaluated the same separately. Multimorbidity was defined as suffering from two or more of nine chronic medical conditions, such as arthritis, stroke, obesity, signs of thyroid hypofunction, obstructive pulmonary symptoms, symptoms of heart failure, impaired vision, hearing impairment, and high blood pressure. The overall prevalence of multimorbidity among the study population was 53.8%, and it was significantly higher among women, illiterates, persons who were single, and persons in the non-poorest quintile. In multivariable logistic regression analyses, female sex and belonging to the non-poorest quintile were independently associated with an increased odds ratio of multimorbidity. The results suggest that the prevalence of multimorbidity is high among the elderly people in rural Bangladesh. Women and the non-poorest group of the elderly people are more likely than men and the poorest people to be affected by multimorbidity. The study sheds new light on the need of primary care for the elderly people with multimorbidity in rural Bangladesh.

    The objective of this study is to determine the prevalence of asthma symptoms and overweight-obese in children aged 6-7 years and adolescents aged 13-14 years within the metropolitan area of Pamplona, and analyse the risk of asthma within the age groups and the influences if sex on this relationship. The study is based on data of asthma symptoms and body mass index of 4,413 children and adolescents obtained from the International Study of Asthma and Allergies phase III questionnaire. Unconditional logistic regression was used to obtain adjusted odds ratios (OR) and 95% confidence intervals (95% CI) for overweight-obesity and asthma symptoms in both groups, taking as reference the group of normal weight. Afterwards, it was stratified by sex. The prevalence of overweight-obesity in the group aged 6-7 years was 23.9% and in the group of teenagers was 11.5%. The prevalence of asthma symptoms in both age groups was lower than the Spanish average. The obese children aged 6-7 years had a higher risk of asthma symptoms. When it was stratified by sex, an increased risk in all asthma symptoms was observed only in obese girls. No relationship between obesity and asthma was observed n the adolescents group. Obesity in children is related to asthma symptoms. Obese girls have an increased risk and more severe asthma symptoms than boys. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA.

    There are no consistent data on the prevalence and bone status of normocalcaemic hypoparathyroidism (NHYPO) as defined by normal adjusted calcium and low PTH level. Our aim was to determine the prevalence and the metabolic bone profile of NHYPO in older women, assessing its evolution over time. The second objective was to evaluate the prevalence of other calcium metabolic disorders. The Osteoporosis and Ultrasound Study (OPUS) is a 6-yr prospective study of fracture-related factors. A total of 2419 older women (age 55-79 yrs) and 258 younger women (age 30-40 yrs) participated. Complete follow-up data were available in 1416 subjects. After calculating the adjusted calcium according to James' formula, we identified 'abnormal' calcium and PTH using Mahalanobis distances and allocated older women into different pathological categories using reference intervals from the healthy young women. We identified 57 subjects with NHYPO (2·4%). These women had lower than expected bone turnover as assessed by bone alkaline phosphatase (-14·5%, 95% CI: -26·2 to -3·0, P = 0·007), CTX (-66·3%, 95% CI: -74·0 to -56·4, P hypoparathyroidism and only 15 (0·6%) subjects had persistent evidence of NHYPO. We also identified 86 subjects (3·6%) affected by hyperparathyroid hypercalcaemia. This is the first large population-based study to investigate NHYPO in older women. NHYPO is fairly common, not always persistent and is characterized by low bone turnover. © 2015 John Wiley & Sons Ltd.

    OBJECTIVES/HYPOTHESIS The aim of this study was to define the co-prevalence of tremor with spasmodic dysphonia (SD). STUDY DESIGN A single institution prospective, case-control study was performed from May 2010 to July 2010. METHODS Consecutive patients with SD (cases) and other voice disorders (controls) were enrolled prospectively. Each participant underwent a voice evaluation and an evaluation for tremor. RESULTS 146 voice disorder controls and 128 patients with SD were enrolled. 26% of patients with SD had vocal tremor, 21% had non-vocal tremor. Patients with SD were 2.8 times more likely to have co-prevalent tremor than the control group (OR = 2.81; 95% CI, 1.55 to 5.08) and only 35% of patients with SD had been seen by a neurologist for the evaluation of dystonia and tremor. CONCLUSIONS Tremor is highly prevalent in patients with SD. It is important for each patient diagnosed with SD to undergo an evaluation for tremor, this is especially important in patients diagnosed with vocal tremor. Level of evidence 3b. PMID:21792965

    Violence against women in families is the most common form of violence against them. The purpose of this study was to determine the prevalence of domestic violence and its effects on married women of Ilam. In this descriptive-sectional research, 334 married women referred to medical health centers in Ilam were selected to participate using a random sampling method. After obtaining their consent to participate in the study, participants responded to a 46 items questionnaire and responses were analyzed using IBM SPSS for Windows ver. 20.0 (IBM Co., Armonk, NY, USA). The majority of the participants reported experiencing domestic violence and emotional violence was more prevalent than other kinds of violence. Logistic regression analysis showed that lower education level, marriage at a younger age, shorter duration of marriage, fewer children, being a housewife, and husband's unemployment had a significant relationship with domestic violence against women. The high prevalence of wife abuse in Ilam especially emotional violence due to lower education levels and marriage at younger age could be a serious threat for women's health as well as for other members of the family. This could be a grounding factor for other social harms such as suicide and this issue must be studied from legal, religious, and cultural standpoints.

    The strikingly higher prevalence of migraine in females compared with males is one of the hallmarks of migraine. A large global body of evidence exists on the sex differences in the prevalence of migraine with female to male ratios ranging from 2:1 to 3:1 and peaking in midlife. Some data are available on sex differences in associated symptoms, headache-related disability and impairment, and healthcare resource utilization in migraine. Few data are available on corresponding sex differences in probable migraine (PM) and other severe headache (ie, nonmigraine-spectrum severe headache). Gaining a clear understanding of sex differences in a range of severe headache disorders may help differentiate the range of headache types. Herein, we compare sexes on prevalence and a range of clinical variables for migraine, PM, and other severe headache in a large sample from the US population. This study analyzed data from the 2004 American Migraine Prevalence and Prevention Study. Total and demographic-stratified sex-specific, prevalence estimates of headache subtypes (migraine, PM, and other severe headache) are reported. Log-binomial models are used to calculate sex-specific adjusted prevalence ratios and 95% confidence intervals for each across demographic strata. A smoothed sex prevalence ratio (female to male) figure is presented for migraine and PM. One hundred sixty-two thousand seven hundred fifty-six individuals aged 12 and older responded to the 2004 American Migraine Prevalence and Prevention Study survey (64.9% response rate). Twenty-eight thousand two hundred sixty-one (17.4%) reported "severe headache" in the preceding year (23.5% of females and 10.6% of males), 11.8% met International Classification of Headache Disorders-2 criteria for migraine (17.3% of females and 5.7% of males), 4.6% met criteria for PM (5.3% of females and 3.9% of males), and 1.0% were categorized with other severe headache (0.9% of females and 1.0% of males). Sex differences were observed in

    Staphylococcus aureus is a major mastitis-causing pathogen. Various genotypes have been recently identified in Switzerland but Staph. aureus genotype B (GTB) was the only genotype associated with high within-herd prevalence. The risk of introducing this Staph. aureus genotype into a herd may be increased by frequent animal movements. This may also be the case when cows from different herds of origin are commingled and share their milking equipment for a limited period of time. The aim of the present study was to determine the prevalence of Staph. aureus GTB in seasonally communal dairy herds before and after a summer period when dairy farming is characterized by mixing cows from different herds of origin in 1 communal operation. In addition, the environment was investigated to identify potential Staph. aureus GTB reservoirs relevant for transmission of the disease. A total of 829 cows from 110 herds of origin in 9 communal operations were included in the study. Composite milk samples were collected from all cows during the first or second milking after arrival at the communal operation and again shortly before the end of the season. Swab samples from the environment, involved personnel, and herding dogs present were collected before the cows arrived. At the end of the season, sampling of personnel was repeated. All samples were analyzed for the presence of Staph. aureus GTB using an established quantitative PCR. At the beginning of the season, Staph. aureus GTB-positive cows were identified in 7 out of 9 communal operations and the within-communal operation prevalence ranged from 2.2 to 38.9%. At the second sampling, all communal operations were Staph. aureus GTB positive, showing within-communal operation prevalence from 1 to 72.1%. The between-herd of origin prevalence increased from 27.3 to 56.6% and the cow-level prevalence increased from 11.2% at the beginning of the season to 29.6% at the end of the season. On 3 different communal operations, Staph. aureus

    Full Text Available Abstract Background The congenital absence of one or more teeth is a dental anomaly that frequently occurs in the world’s population with a wide variability of distribution. The aim of this study is to assess the current prevalence of dental agenesis in the permanent dentition (excluding third molars using a sample of Italian orthodontic patients. Methods Panoramic radiographs of 4006 Caucasian children between 9 and 16 years of age (1865 males and 2141 females performed over a 5-year period (from 2010 to 2015 were carefully examined to identify congenital missing teeth. A chi-square test was used to determine the difference in the prevalence of hypodontia between genders and between arches. Results The prevalence of dental agenesis was 9% (9.1% for females and 8.7% for males. The most common congenitally missing teeth were the mandibular second premolars (20.3 and 18.1% followed by the upper lateral incisors (17.8 and 17.7% and the maxillary second premolars (7.4 and 6.3%. The absence of one tooth to five teeth was observed in 344 patients (8.6%, while 15 patients showed from six to nine missing teeth (0.4%. The analysis showed 363 cases of agenesis in the upper arch (0.64% and 339 in the lower arch (0.60%. Unilateral (4.6% and bilateral (4.4% agenesis demonstrated a similar frequency. The most common bilateral missing teeth were the mandibular second premolars (1.9% and the maxillary lateral incisors (1.6%. Conclusions The results of this study observed a higher prevalence of hypodontia compared to previous studies conducted on the Italian population. Thus, a detailed and careful radiographic examination was important in diagnosing one or more missing teeth. This could help plan the best possible treatments, both esthetically and functionally, for these patients.

    Full Text Available Dysmenorrhea or pain during menstruation is the most common gynaecological complaint among adolescents and college students. A good majority of patients with dysmenorrhea also experience pre - menstrual symptoms ( PMS . The objective of this cross s ectional study was to assess prevalence of dysmennorhea , PMS , college absenteeism and knowledge attitudes and practices relating to the same among college going students between the age of 18 to 26 years. METHODS: A cross s ectional analysis of a total of 420 students using questionnaires related to dysmenorrhea was done . The questionnaire dealt with the regularity of menstrual cycles , occurrence of dysmenorrhea , college absenteeism , premenstrual symptoms and lifestyle attributes of the students. RESULTS: The prevalence of dysmenorrhea of varying degrees was found to be as high as 97 percent . Dysmennorhea was seen in 45.8 percent of students with regular cycles and 97.7 percent of students with irregular cycles. 47.5 percentage of students missed their college working days due to menstruation related complaints. Among the students who had pre - menstrual syndrome , majority of them revealed life style attributes like eating fast food and also consuming over the counter pain medicines. Also psychological and emotional changes were commonly seen during the premenstrual phase. CONCLUSION: This study showed that though dysmennorhea of varying degrees is widely prevalent among college going students , the prevalence of pre - menstrual syndrome was higher. The study suggests that adequate counseling and education about menstrual symptoms and abuse of OTC analgesics if made a part of college curriculum as well as lifestyle modifications could come a long way in helping to alleviate the problems college students face due to dysmennorhea and PMS.

    SUMMARY Background & aims Previous studies have suggested that cocoa products, which are rich sources of flavonoids, may lower blood pressure, serum cholesterol, fasting blood glucose and improve endothelial function. However, it is unclear whether consumption of cocoa products including chocolate influences the risk of metabolic syndrome (MetS). In a cross-sectional design, we sought to examine the association between chocolate consumption and the prevalence of MetS. Methods We studied 4098 participants from the National Heart, Lung, and Blood Institute (NHLBI) Family Heart Study aged 25–93 years. Chocolate consumption was assessed using a semi-quantitative food-frequency questionnaire. MetS was defined using the NCEP III criteria. Generalized estimating equations were used to estimate prevalence odds ratios of MetS according to frequency of chocolate intake. Results Of the 4098 participants (mean age 51.7 y) included in the analyses, 2206 (53.8%) were female. The prevalence of metabolic syndrome in our population was 30.2%. Compared with those who did not consume any chocolate, multivariate adjusted odds ratios (95% CI) for MetS were 1.26 (0.94, 1.69), 1.15 (0.85, 1.55), and 0.99 (0.66, 1.51) among women who reported chocolate consumption of 1–3 times/ month, 1–4 times/week, and 5+ times/week, respectively. Corresponding values for men were: 1.13 (0.82, 1.57), 1.02 (0.74, 1.39), and 1.21 (0.79, 1.85). Conclusion These data do not support an association between chocolate intake and the prevalence of MetS in US adult men and women. PMID:25126517

    Impulse control disorders/other compulsive behaviours ('ICD behaviours') occur in Parkinson's disease (PD), but prospective studies are scarce, and prevalence and clinical characteristics of patients are insufficiently defined. To assess the presence of ICD behaviours over a 2-year period, and evaluate patients' clinical characteristics. A prospective, non-interventional, multicentre study (ICARUS (Impulse Control disorders And the association of neuRopsychiatric symptoms, cognition and qUality of life in ParkinSon disease); SP0990) in treated Italian PD outpatients. Study visits: baseline, year 1, year 2. Surrogate primary variable: presence of ICD behaviours and five ICD subtypes assessed by modified Minnesota Impulsive Disorder Interview (mMIDI). 1069/1095 (97.6%) patients comprised the Full Analysis Set. Point prevalence of ICD behaviours (mMIDI; primary analysis) was stable across visits: 28.6% (306/1069) at baseline, 29.3% (292/995) at year 1, 26.5% (245/925) at year 2. The most prevalent subtype was compulsive eating, followed by punding, compulsive sexual behaviour, gambling and buying disorder. Patients who were ICD positive at baseline were more likely to be male, younger, younger at PD onset, have longer disease duration, more severe non-motor symptoms (including mood and sexual function), depressive symptoms, sleep impairment and poorer PD-related quality of life. However, they did not differ from the ICD-negative patients in their severity of PD functional disability, motor performance and cognitive function. Prevalence of ICD behaviours was relatively stable across the 2-year observational period. ICD-positive patients had more severe depression, poorer sleep quality and reduced quality of life. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    To determine the prevalence of and factors associated with amblyopia in a rural Chinese population. Population-based, cross-sectional study. Six thousand eight hundred thirty Han Chinese aged 30 years or more, recruited from Yongnian County, Handan, Hebei Province, China. Thirteen villages in the Yongnian County of Handan were selected randomly, and residents of these selected villages 30 years of age or older were invited to participate in the Handan Eye Study. Participants underwent a comprehensive eye examination, including standardized visual acuity (VA) tests using logarithm of the minimum angle of resolution charts. Prevalence rates were age- and gender-standardized to the 2000 China census. The proportion of rural Chinese population aged 30 years or older with amblyopia. Unilateral amblyopia was diagnosed if best-corrected VA (BCVA) was 20/32 or worse in the amblyopic eye and was not attributable directly to any underlying structural abnormality of the eye or visual pathway. Bilateral amblyopia was diagnosed if BCVA was 20/32 or less in both eyes and if there was a history of form deprivation during the sensitive period of visual development, such as media opacities or high, uncorrected ametropia. Amblyopia was diagnosed in 205 participants, with an age- and gender-adjusted prevalence of 2.8%. Of these, 1.7% were unilateral cases and 1.1% were bilateral cases. Underlying causes included anisometropia (67.3%), strabismus (5.4%), mixed strabismus and anisometropia (4.4%), visual deprivation (9.8%), astigmatism association (9.8%), and other (3.4%). Of the amblyopia cases, 47.6% were hypermetropic. In this rural Chinese population, 2.8% of adults 30 to 80 years of age had amblyopia, a prevalence rate broadly consistent with that of most other studies. One third of the cases were bilateral, and anisometropia was the most common cause of this condition. Copyright © 2011 American Academy of Ophthalmology. Published by Elsevier Inc.

    Diabetic retinopathy (DR) is the leading cause of blindness in people of working age. The purpose of this paper is to report the prevalence and cardiovascular associations of diabetic retinopathy and maculopathy (DMac) in Germany. The Gutenberg Health Study (GHS) is a population-based study with 15,010 participants aged between 35 at 74 years from the city of Mainz and the district of Mainz-Bingen. We determined the weighted prevalence of DR and DMac by assessing fundus photographs of persons with diabetes from the GHS data base. Diabetes was defined as HbA1c ≥ 6.5%, known diagnosis diabetes mellitus or known diabetes medication. Furthermore, we analysed the association between DR and cardiovascular risk factors and diseases. Overall, 7.5% (1,124/15,010) of the GHS cohort had diabetes. Of these, 27.7% were unaware of their disease and thus were newly diagnosed by their participation in the GHS. The prevalence of DR and DMac was 21.7% and 2.3%, respectively among patients with diabetes. Vision-threatening disease was present in 5% of the diabetic cohort. In the multivariable analysis DR (all types) was associated with age (Odds Ratio [95% confidence interval]: 0.97 [0.955-0.992]; p = 0.006) arterial hypertension (1.90 [1.190-3.044]; p = 0.0072) and vision-threatening DR with obesity (3.29 [1.504-7.206]; p = 0.0029). DR (all stages) and vision-threatening DR were associated with duration of diabetes (1.09 [1.068-1.114]; pdiabetic retinal disease in Germany [corrected].Prevalence of DR was lower in the GHS compared to East-Asian studies. Associations were found with age, arterial hypertension, obesity, and duration of diabetes mellitus.

    Full Text Available Hyponatremia is the most frequently encountered electrolyte abnormality among hospitalized patients and thiazide users. In this large single-center retrospective study, we aim to determine the prevalence and risk factors of hyponatremia among patients at the King Abdulaziz Medical City (KAMC, Riyadh, Saudi Arabia.To the best of our knowledge, this is the first such study in Saudi Arabia. A chart review was done for the years 2011-2012 of all admitted Saudi patients at KAMC who were treated with indapamide and hydrochlorothiazide. A total of 2000 patients were included [1237 females (629 indapamide and 608 hydrochlorothiazide and 762 males (371 indapamide and 391 hydrochlorothiazide]. Majority of the patients had type-2 diabetes mellitus (T2DM with an overall prevalence of 72.2%. The overall prevalence of hyponatremia, regardless of severity, in the indapamide group was 37.3% versus 38.7% in the hydrochlorothiazide group. Stratification for age revealed that older patients had relatively higher levels of sodium (Na as compared with younger patients, and this inverse association was significant (R = - 0.123; P <0.001. Increasing age, female gender and presence of T2DM were the significant risk factors for hyponatremia, explaining the 4.7% of the variance perceived (P <0.001. Our study suggests that the prevalence of hyponatremia among Saudi thiazide users is relatively high, and more so for the elderly and for those with T2DM. Early identification of this condition is important and caution should be exercised while prescribing thiazide drugs, particularly to those who are most at risk of developing hyponatremia to prevent related complications.

    Atrial fibrillation (AF) is a major factor for stroke and stroke-associated mortality, and its incidence is increasing during the last decades. There are only scarce data about its prevalence in Greece. We designed an epidemiological cross-sectional study to estimate the prevalence of AF in Greece and evaluate the adequacy of anticoagulant treatment in AF patients. The Arcadia Rural Study on Atrial Fibrillation (ARSAF) was conducted between 2002-2003 in five rural villages of the Arcadia province (Greece) with a permanent population of 1312 individuals. Patients had a thorough medical examination and electrocardiogram, and information was collected about their medical history and comorbidities. CHADS2 score was used to determine stroke risk for participants with AF. 1155 subjects (88% of the entire population) participated in the study. The overall prevalence of AF was 3.9% showing an increasing trend with increasing age ranging from 0.4% in patients 84 years. Among patients with AF, 14 (32%) had paroxysmal AF. The presence of AF was associated with increasing age (OR: 1.67 for every 10 years increase, 95% CI: 1.26-2.15), hypertension (OR: 2.12, 95% CI: 1.02-4.14), heart failure (OR: 11.85, 95% CI: 4.92-28.56) and prior cerebrovascular disease (OR: 4.17, 95% CI: 1.44-12.06). Among these subjects with AF, 12 (26.6%) were considered as low-risk (CHADS2 = 0), 18 (40.0%) as intermediate-risk (CHADS2 = 1), and 15 (33.3%) as high-risk (CHADS2 > 1) patients for stroke. 25 (55.5%) patients with AF did not receive appropriate antithrombotic treatment. The prevalence of AF in Greece is similar to other countries and increases with increasing age.

    After the first outbreak of Legionnaire disease was described for the first time in1976, legionellosis has been increasingly recognized in association with many outbreaks, both community and hospital acquired. This disease remains a model of water borne transmission. In Lebanon, no report has yet been published on the prevalence of Legionella pneumophila infections. This study aims to evaluate the prevalence of legionellosis in hospitalized patients with community acquired pneumonia (CAP) and in patients with nosocomial pneumonia (HAP). The study was conducted between April 2004 and August 2007. Eleven community hospitals participated to this endeavour. Laboratory evaluation was conducted in two centers (Middle East Health Institute, Bsalim, Lebanon and Nini Hospital, Tripoli, Lebanon). Two hundred and forty two urinary samples and ninety one pulmonary samples from 242 patients were analyzed. The age range was 16 to 71 years. Two hundred and fifteen were from community acquired pneumonias and twenty seven were nosocomially acquired in intensive care units. The urinary antigen was investigated in 242 patients; the Binax kit ® was used in this research. In lung secretions of 91 patients, the presence of Legionella pneumophila was searched for using direct immunofluorescence method and culture. Among the 215 urinary samples from patients with CAP, three were positive for Legionella antigen with a prevalence of 1.4 %. Among the 27 patients with HAP, one was positive for Legionella antigen with a prevalence of 3.7%. This preliminary study reveals the fact that legionellosis is indeed present in Lebanon, hence the importance of considering it in the work-up and the management of patients with pneumonia. Hospital laboratories should therefore routin ely search for this pathogen through at least urinary antigen detection. Health authorities should also enforce microbiological regulations concerning water sanitation in hospitals and in the community to prevent the

    Previous studies have suggested that cocoa products, which are rich sources of flavonoids, may lower blood pressure, serum cholesterol, fasting blood glucose and improve endothelial function. However, it is unclear whether consumption of cocoa products including chocolate influences the risk of metabolic syndrome (MetS). In a cross-sectional design, we sought to examine the association between chocolate consumption and the prevalence of MetS. We studied 4098 participants from the National Heart, Lung, and Blood Institute (NHLBI) Family Heart Study aged 25-93 years. Chocolate consumption was assessed using a semi-quantitative food-frequency questionnaire. MetS was defined using the NCEP III criteria. Generalized estimating equations were used to estimate prevalence odds ratios of MetS according to frequency of chocolate intake. Of the 4098 participants (mean age 51.7 y) included in the analyses, 2206 (53.8%) were female. The prevalence of metabolic syndrome in our population was 30.2%. Compared with those who did not consume any chocolate, multivariate adjusted odds ratios (95% CI) for MetS were 1.26 (0.94, 1.69), 1.15 (0.85, 1.55), and 0.99 (0.66, 1.51) among women who reported chocolate consumption of 1-3 times/ month, 1-4 times/week, and 5+ times/week, respectively. Corresponding values for men were: 1.13 (0.82, 1.57), 1.02 (0.74, 1.39), and 1.21 (0.79, 1.85). These data do not support an association between chocolate intake and the prevalence of MetS in US adult men and women.

    What is the prevalence of polycystic ovary syndrome (PCOS) in Han Chinese women from different communities? The prevalence of PCOS in Chinese women aged 19-45 years is 5.6%. The prevalence of PCOS is reported to range from 5 to 10% but to the best of our knowledge the Han Chinese population has not been studied. A large-scale epidemiological study was carried out between October 2007 and September 2011 in 15 924 Han Chinese women of reproductive age (19-45 years) from the 10 provinces and municipalities in China. A total of 16 886 women from 152 cities and 112 villages were involved in the study. All study participants received a questionnaire and underwent a physical and transvaginal ultrasound examination. Blood samples were collected from a subsample of women (n = 3565) for analysis of metabolic markers and hormones. Based on the Rotterdam PCOS criteria, we assessed hyperandrogenism (H), chronic anovulation (O) and polycystic ovaries (P). Following diagnosis, women with PCOS were assigned to one of four different phenotypes. Finally, the prevalence and related risks of PCOS among Chinese women were estimated based on all the data sources. A total of 16 886 women were initially involved in the study and 15 924 eligible participants then completed the study; the overall response rate was 94.3% (15 924/16 886). The prevalence of PCOS in the Chinese community population was 5.6% (894/15 924). Blood samples were analyzed from 833 of these women who were assigned to the four PCOS phenotypes as follows: 19% H + O, 37% H + P, 15% O + P and 29% H + O + P. Comparing the 833 women with PCOS to 2732 women without PCOS indicated that PCOS occurs in younger women (P < 0.05) and these women were prone not only to menstrual problems, hyperandrogenism, PCO and infertility but also metabolic syndrome (MS) and insulin resistance (IR). However, there was no significant difference in the rate of hypertension or hyperlipemia between the two groups. Obese patients with PCOS had a

    Population-based cross-sectional study was performed to estimate the prevalence of chemical intolerance and to examine the characteristics of the sample. A Web-based survey was conducted that included 7,245 adults in Japan. The criteria for chemical intolerance proposed by Skovbjerg yielded a prevalence of 7.5% that was approximately consistent with that reported from a Danish population-based survey. Female gender, older age, and renovation in the house during the past 7 years were positively associated with chemical intolerance. Improvements in the condition were observed with daily ventilation habits. Medical history of atopic dermatitis, allergic rhinitis, food allergy, multiple chemical sensitivity, and depression were associated with chemical intolerance. Fatigue, depressed mood, and somatic symptoms were also positively correlated with chemical intolerance. Better elucidation of the causes, comorbidities, concomitants, and consequences of chemical intolerance has the potential to provide effective solutions for its prevention and treatment.

    In the last decades, the use of the epidemiological prevalence ratio (PR) instead of the odds ratio has been debated as a measure of association in cross-sectional studies. This article addresses the main difficulties in the use of statistical models for the calculation of PR: convergence problems, availability of tools and inappropriate assumptions. We implement the direct approach to estimate the PR from binary regression models based on two methods proposed by Wilcosky & Chambless and compare with different methods. We used three examples and compared the crude and adjusted estimate of PR, with the estimates obtained by use of log-binomial, Poisson regression and the prevalence odds ratio (POR). PRs obtained from the direct approach resulted in values close enough to those obtained by log-binomial and Poisson, while the POR overestimated the PR. The model implemented here showed the following advantages: no numerical instability; assumes adequate probability distribution and, is available through the R statistical package.

    Mucosal infection with high-risk human papiloma virus(HPV) types 16 and 18 is the cause of cervical cancer and might be a subset of oral squamous cell carcinoma (OSCC), yet the prevalence and type distribution of HPV in oral SCC remained unclear. We systematically reviewed published studies of OSCC biopsies, which were employed to detect and genotype HPV through different methods. The aim of this investigation is to carry out a bibliographic review on the prevalence of HPV in OSCC and normal oral mucosa.

    The goal of this study was to verify the prevalence of nutritive (breast-feeding and bottle-feeding) and non-nutritive (pacifier) sucking habits, the methods used to eliminate them, and success of these methods. To collect the data, 502 questionnaires were distributed to parents of 0- to 6-year-old children. Bottle-feeding was used by 83% and pacifier by 63% of children. The professional's explanation, the use of substances on the pacifier, the abrupt interruption of the habit, and parents' explanations were efficient in 90%, 80%, 64%, and 38% of the cases, respectively. Sucking habits had a high prevalence in this sample. An indirect linear relationship between breast-feeding and pacifier use demonstrated that the more the child was breast-fed, the less the pacifier was used. The most efficient method to end the pacifier-sucking habit was professional explanation; however, it was used less often.

    Policing is regarded as a high-risk profession for the development of mental health disturbances owing to various critical incidents and potential traumatic events they encounter. Exploration of mental health problems in policing in Sri Lanka, which recently concluded a civil war expanded over three decades, is a timely, yet, a neglected issue. Hence, the present study was conducted with the aim of determining the prevalence and associated factors of depression among police officers in the Kandy police division, Sri Lanka. A cross sectional study was conducted using a simple random sample of 750 police officers employed in the Kandy police division, Sri Lanka. A self administered questionnaire, including "Peradeniya Depression Scale" to assess depression, was used to collect data. The prevalence of depression was calculated as point prevalence with 95 % confidence intervals. Multivariable logistic regression was carried out using backward elimination method to quantify the association between depression and selected predictors identified at bivariate analysis at p Sri Lanka. Given the modifiable nature of the significant predictors, it is recommended to design a package of interventions and implement adaptive measures to rectify the problems related to depression among police officers.

    Myasthenia gravis (MG) is an autoimmune disease caused by a failure of neuromuscular transmission. Familial clustering has been reported despiteMG usually manifesting as a sporadic condition presumed not to be inherited. Our study investigated the prevalence of FAMG in a Spanish cohort, characterizing their phenotype,antibody titres and thymus findings. We investigated the presence of familial cases in 462 MG patients, characterizing by age and MGFA class at debut, quantitative MG score, antibody titres, MGFA post-intervention status and thymus pathology. Sixteen cases from8 unrelated pedigrees were identified. The prevalence of FAMG caseswas 3.46%.Mean age at onset was 57.8 ± 17.4 years (range=23–82). Distribution at debut was: 6 ocular, 4 IIa, 4IIb, 1 IIIa and 1 IIIb. Thymoma was identified in two of the 7 thymectomized individuals. The prevalence of FAMG in Spain is similar to other populations. Post-intervention status did not differ from sporadic autoimmune MG. As in other neuromuscular disorders, phenotype and inheritance heterogeneity are present in FAMG. In addition to the interfamilial heterogeneity observed, members of the same family affected with FAMG may even present different ages of onset, severity and thymus involvement. Further studies are necessary to clarify the role of genetic risk factors in this form of autoimmune MG.

    As a Burden of Obstructive Lung Disease (BOLD) collaboration, we studied the prevalence of chronic obstructive pulmonary disease (COPD) and its associated risk factors in a suburban population in Malaysia. Nonhospitalized men or women of age ≥ 40 years from a Penang district were recruited by stratified simple random sampling. Participants completed detailed questionnaires on respiratory symptoms and exposure to COPD risk factors. Prebronchodilator and post-bronchodilator spirometry conducted was standardized across all international BOLD sites in device and data quality control. Of the 1218 individuals recruited for the study, 663 (340 men and 323 women) had complete questionnaire data and acceptable post-bronchodilator spirometry. The estimated population prevalence of Global Initiative for Chronic Obstructive Lung Disease (GOLD) ≥ stage I was 6.5% or 3.4% based on either fixed forced expiratory volume in 1 s/forced vital capacity ratio of population-based epidemiology data on COPD for Malaysia. Compared with other sites globally, our estimated population prevalence was relatively low. In addition to cigarette smoking, use of biomass fuel and exposure to dusty job represented significant risk to the development of COPD. © 2016 Asian Pacific Society of Respirology.

    Purpose: The aim of this pharmaco-epidemiological study was to evaluate the prevalence of oropharyngeal candidiasis (OPC) in cancer patients treated with chemotherapy and/or radiotherapy. Methods and Materials: Signs and symptoms of OPC were noted for all patients. Antifungal therapeutic management was recorded in OPC patients. Patients receiving local antifungal treatments were monitored until the end of treatment. Results: Enrolled in the study were 2,042 patients with solid tumor and/or lymphoma treated with chemotherapy and/or another systemic cancer treatment and/or radiotherapy. The overall prevalence of OPC was 9.6% (95% confidence interval, 8.4%-11.0%] in this population. It was most frequent in patients treated with combined chemoradiotherapy (22.0%) or with more than two cytotoxic agents (16.9%). Local antifungal treatments were prescribed in 75.0% of OPC patients as recommended by guidelines. The compliance to treatment was higher in patients receiving once-daily miconazole mucoadhesive buccal tablet (MBT; 88.2%) than in those treated with several daily mouthwashes of amphotericin B (40%) or nystatin (18.8%). Conclusion: OPC prevalence in treated cancer patients was high. Local treatments were usually prescribed as per guidelines. Compliance to local treatments was better with once-daily drugs.

    The aim of this study was to investigate the prevalence of molar incisor hypomineralization (MIH) and its relationship with systemic conditions in a group of Iranian children. The study population comprised of 433 7-9 year olds, from four schools in Zahedan, Iran. Subjects were evaluated clinically by one examiner, and at a separate session, their mothers completed a coded medical history questionnaire. Hypo-mineralized molars and incisors were recorded based on DDE (developmental defects of enamel) index and DMFT (number of decayed, filled and missing teeth) was determined. Statistical analyses were performed using Chi-square and independent sample t-tests. Fifty-five (12.7%) children showed MIH. The overall mean number of affected teeth was 0.2. The mean value of DMFT in MIH children was greater than in normal children. Demarcated opacities were the most frequent (76%) enamel defect. Mother's and child's medical problems during prenatal, perinatal and post natal period were significantly remarkable in MIH children. The prevalence of MIH in a group of Iranian children was 12.7%. Prenatal, perinatal and post natal medical conditions were more prevalent in children affected by MIH.

    The aim of this study was to apply methodological procedures to determine the prevalence of adequacy of Iron and vitamin C in children's diets. It was included 238 children aged 2 to 3 years enrolled in 2009 in 25 day care centers in the municipality of Rio de Janeiro. Dietary intake was assessed by weighing the food and food record. Assessing the prevalence of nutrient adequacy took into consideration the individual and the group. The best estimate of the needs of the individual is given by the estimated average requirement (EAR), since we do not know the true needs of the individual who is being evaluated. To estimate the need of the group method was used EAR as the cutoff. The prevalence of adequacy of iron and vitamin C in children's diets was 91.2 and 62.2%, respectively. All necessary to achieve the method EAR as the cutoff were used, but became unviable the adjustment of the observed consumption data to estimate the distribution of usual intake in this group. We conclude that the study of probability of adequacy of habitual diet in iron and vitamin C in the age group in question was only possible with the use of procedures for the individual.

    Except for dementia and depression, little is known about common mental disorders in elderly people. To estimate current, 12-month and lifetime prevalence rates of mental disorders in different European and associated countries using a standardised diagnostic interview adapted to measure the cognitive needs of elderly people. The MentDis_ICF65+ study is based on an age-stratified, random sample of 3142 older men and women (65-84 years) living in selected catchment community areas of participating countries. One in two individuals had experienced a mental disorder in their lifetime, one in three within the past year and nearly one in four currently had a mental disorder. The most prevalent disorders were anxiety disorders, followed by affective and substance-related disorders. Compared with previous studies we found substantially higher prevalence rates for most mental disorders. These findings underscore the need for improving diagnostic assessments adapted to the cognitive capacity of elderly people. There is a need to raise awareness of psychosocial problems in elderly people and to deliver high-quality mental health services to these individuals. © The Royal College of Psychiatrists 2017.

    To provide information and comparison pertaining to visual impairment of Maori children with other children in New Zealand in particular: prevalence of blindness, causes of visual impairment, and avoidable causes of visual impairment. Retrospective data collection utilising the WHO/PBL eye examination record for children with blindness and low vision at Blind and Low Vision Education Network New Zealand (BLENNZ), Homai. Individuals not of Maori ethnicity or over the age of 16 were excluded from the study. 106 blind and 64 low-vision Maori children were studied. The main cause of blindness in Maori children is cortical visual impairment. Twenty-eight percent of causes of blindness in this population are potentially avoidable with non-accidental injury as the main cause. The prevalence of blindness and low vision in children amounts to 0.05% and 0.03%, respectively. The prevalence and causes of childhood blindness are comparable to the other ethnic groups in New Zealand. The main difference lies in avoidable causes of blindness, which appeared to be much higher in the Maori population. The leading cause of avoidable blindness in Maori children is caused by non-accidental injuries.

This cross-sectional, multicenter epidemiologic study enrolled 9348 hospitalized patients older than 18 y in Latin America. Student's t test and chi-square tests were used to analyze univariate analysis and multiple logistic regression analysis, respectively. Malnutrition was present in 50.2% of the patients studied. Severe malnutrition was present in 11.2% of the entire group. Malnutrition correlated with age (>60 y), presence of cancer and infection, and longer length of hospital stay (P policies ruling the practice of nutritional therapy exist only in Brazil and Costa Rica. Hospital malnutrition in Latin America is highly prevalent. Despite this prevalence, physicians' awareness of malnutrition is weak, nutritional therapy is not used routinely, and governmental policies for nutritional therapy are scarce.

    Malignant diseases have been believed to be more common in some areas of Eastern Morocco, but until now, cancer patterns have not been reported for this region. In this paper we present for the first time the cancer prevalence analysis in Eastern Morocco. Cross-sectional study carried out among all patients diagnosed and/or treated with cancer at the Hassan II Regional Oncology Center (ROC) since it was established in October 2005 until December 2012. The ROC is the only hospital specialized in cancer care in Eastern Morocco. A total of 8,508 cases of cancer were registered among residents in Eastern Morocco, with a female to male ratio of 2.1. The mean age at diagnosis was 53.9 ± 15.2 years (median age = 53 years). Thus, unlike in Western countries, cancer in Eastern Morocco afflicts younger population. The areas of Eastern Morocco did not differ significantly by mean age at diagnosis (p = 0.061). However, these regions differed significantly by sex ratio (p Morocco was observed, both in males and females (p Morocco differed significantly by cancer prevalence (p Morocco. Our study illustrates substantial differences in cancer patterns between areas of Eastern Morocco. These findings are important for cancer control and highlight the need to develop program aiming at controlling and preventing the spread of major cancer sites in Eastern Morocco, particularly in areas with increased cancer prevalence rates.

    Background: Health literacy is an increasingly important public health concern. However, little is known about the health literacy of general public in China. The aim of this study was to evaluate the prevalence of low health literacy and demographic associations in Shanghai, China. Methods: This study was a community-based cross-sectional health survey utilizing a multi-stage random sampling design. The sample consisted of 1360 individuals aged 15-69 years with the total community-dwelling Chinese as the sample frame. Health literacy was measured by a questionnaire developed on the basis of a national health literacy manual released by the Chinese Ministry of Health. Multiple logistic regression models were used to identify whether common socio-demographic features were associated with health literacy level. Results: The prevalence of low health literacy was 84.49% (95% CI, 82.56% to 86.41%). The prevalence of low health literacy was negatively associated with the level of education, occupation, and annual household income, but was not associated with gender, age, or the presence of non-communicable chronic disease. Conclusions: Simplifying health services, enhancing health education, and promoting interventions to improve health literacy in high-risk populations should be considered as part of the strategies in the making of health policy in China.

    To compare the prevalence and predictors of alcohol use in multiple cohorts. Cross-cohort comparison of retrospective and prospective studies. Population-based studies in Ireland, the UK, Australia and New Zealand. 17,244 women of predominantly Caucasian origin from two Irish retrospective studies (Growing up in Ireland (GUI) and Pregnancy Risk Assessment Monitoring System Ireland (PRAMS Ireland)), and one multicentre prospective international cohort, Screening for Pregnancy Endpoints (SCOPE) study. Prevalence of alcohol use pre-pregnancy and during pregnancy across cohorts. Sociodemographic factors associated with alcohol consumption in each cohort. Alcohol consumption during pregnancy in Ireland ranged from 20% in GUI to 80% in SCOPE, and from 40% to 80% in Australia, New Zealand and the UK. Levels of exposure also varied substantially among drinkers in each cohort ranging from 70% consuming more than 1-2 units/week in the first trimester in SCOPE Ireland, to 46% and 15% in the retrospective studies. Smoking during pregnancy was the most consistent predictor of gestational alcohol use in all three cohorts, and smokers were 17% more likely to drink during pregnancy in SCOPE, relative risk (RR)=1.17 (95% CI 1.12 to 1.22), 50% more likely to drink during pregnancy in GUI, RR=1.50 (95% CI 1.36 to 1.65), and 42% more likely to drink in PRAMS, RR=1.42 (95% CI 1.18 to 1.70). Our data suggest that alcohol use during pregnancy is prevalent and socially pervasive in the UK, Ireland, New Zealand and Australia. New policy and interventions are required to reduce alcohol prevalence both prior to and during pregnancy. Further research on biological markers and conventions for measuring alcohol use in pregnancy is required to improve the validity and reliability of prevalence estimates.

    Many autoimmune diseases, including rheumatoid arthritis (RA), share common mechanisms; however, population-based studies of the magnitude of multiple autoimmune diseases in patients with RA have not been performed. We conducted a cross-sectional study using a US administrative healthcare thcare claims database to screen for prevalence of multiple autoimmune diseases in patients with RA and osteoarthritis (OA). Each patient diagnosed with RA between January 1, 2006 and September 30, 2014 was age- and sex-matched with five patients with OA. The prevalence of 37 pre-specified autoimmune diseases during the 24-month period before and after RA or OA diagnosis was compared. Overall, 286,601 patients with RA and 992,838 matched patients (from 1,421,624 records) with OA were evaluated. During the baseline period, at least one and more than one autoimmune diseases were identified in 24.3% and 6.0% of patients with RA compared with 10.5% and 1.4% of patients with OA, respectively. Highest prevalence rates for patients with RA were for systemic lupus erythematosus (3.8% versus 0.7% for OA) and psoriatic arthritis (3.2% versus 0.4%). Highest odds ratios (ORs) comparing RA with OA were for the prevalence of ankylosing spondylitis (OR 8.0; 95% CI 7.6, 8.5) and psoriatic arthritis (OR 7.8; 95% CI 7.6, 8.1). Patients with RA have more concurrent autoimmune diseases than patients with OA. These data suggest that the interrelationship between RA and other autoimmune diseases, and outcomes associated with the occurrence of multiple autoimmune diseases, may play an important role in disease understanding, management, and treatment decisions.

    There are limited population based data on the prevalence of asthma in China. The China Asthma and Risk factors Epidemiologic (CARE) survey was designed to understand the prevalence and risk factors for asthma in mainland China. The CARE survey aims to demonstrate the prevalence and risk factors of asthma in mainland China among adolescents (age >14 years) and adults. The survey was performed between February 2010 and August 2012 in eight provinces/cities of seven areas in mainland China. The inhabitants (age, >14 years) recruited in this survey were through multi-stage cluster random sampling. Asthma diagnosis was based on medical history and lung function tests. Multivariable logistic regression was used to analyzed the risk factors for asthma. The study included 164 215 subjects (men, 79 692 [48.53%]; women, 84 523 [51.47%]). 2034 (1.24%) were asthmatic patients. Among all asthmatic patients, 521 (25.61%) were newly diagnosed. Univariable regression analysis showed that risk factors for asthma included smoking, first-degree relatives with asthma, allergic rhinitis, chronic bronchitis, COPD, pollinosis, allergic pneumonia, concomitant allergic diseases, BMI and raising pets. Multivariable logistic regression indicated that asthma risk factors included women, age stratification, smoking, first-degree relatives suffering from asthma or pollinosis, combined with allergic rhinitis, eczema or GERD. We speculated that the prevalence of asthma is increasing in mainland China among individuals aged >14 years in the past 10 years. A number of risk factors were identified. The risk factors of asthma would be further elucidated in our future work. Our CARE study highlights that asthma epidemic in mainland China should be paid more attention. Copyright © 2018.

    Malaria has traditionally been a leading public health problem in Equatorial Guinea. After completion, in September 2011, of the integrated set of interventions against malaria launched by the Global Fund Malaria Programme in the mainland area, the epidemiological situation of malaria remains unknown. The aim of this study was to investigate the prevalence rate of malaria and associated factors based on the rapid diagnosis test (RDT) in Bata district, in order to provide evidence that will reinforce the National Malaria Control Programme. From June to August 2013, a representative cross sectional survey using a multistage, stratified, cluster-selected sample was carried out in urban zones and rural villages from Bata district. Data on socio-demographic, health status and malaria-related behaviours was collected. Malaria diagnosis was performed by RDT. Bivariate and multivariable statistical methods were employed to assess malaria prevalence and its association with different factors. Prevalence of malaria was higher in rural settings (58.9 %; CI 95 % 55.2-62.5 %) than in the sampled urban communities (33.9 %; CI 95 % 31.1-36.9 %). Presence of anaemia was also high, especially in rural sites (89.6 vs. 82.8 %, p age group, the most affected age range being 13 months-14 years old. Other significant covariates were ethnic group (only in urban sites), number of adults living in the house (only in rural villages) previous history of fever, anaemia (only in urban sites) and sleeping under a bed net. Moreover, those who never slept under a bed net were two times more likely to have malaria. The prevalence of malaria was high in Bata district, especially in rural villages. The National Programme to fight malaria in Equatorial Guinea should take into account the differences found between rural and urban communities and age groups to target appropriately those worst affected. The findings of this study will assist in planning and undertaking regional policy and other

    Full Text Available Abstract Background Chlamydia trachomatis infection (CTI is the most frequent sexual transmitted disease (STI in Switzerland but its prevalence in undocumented migrants is unknown. We aimed to compare CTI prevalence among undocumented migrants undergoing termination of pregnancy (ToP to the prevalence among women with residency permit. Methods This prospective cohort study included all pregnant, undocumented women presenting from March 2005 to October 2006 to the University hospital for ToP. The control group consisted of a systematic sample of pregnant women with legal residency permit coming to the same hospital during the same time period for ToP Results One hundred seventy five undocumented women and 208 women with residency permit (controls were included in the study. Mean ages were 28.0 y (SD 5.5 and 28.2 y (SD 7.5, respectively (p = 0.77. Undocumented women came primarily from Latin-America (78%. Frequently, they lacked contraception (23%, controls 15%, OR 1.8, 95% CI 1.04;2.9. Thirteen percent of undocumented migrants were found to have CTI (compared to 4.4% of controls; OR 3.2, 95% CI 1.4;7.3. Conclusion This population of undocumented, pregnant migrants consisted primarily of young, Latino-American women. Compared to control women, undocumented migrants showed higher prevalence rates of genital CTI, which indicates that health professionals should consider systematic screening for STI in this population. There is a need to design programs providing better access to treatment and education and to increase migrants' awareness of the importance of contraception and transmission of STI.

    Neck pain is a musculoskeletal condition with high prevalence that may affect the physical, social, and psychological aspects of the individual, contributing to the increase in costs in society and business. To determine the prevalence of neck pain and associated factors in a population-based sample of adults aged 20 and more. Cross-sectional study based on a population survey. A total number of 600 individuals were interviewed in their homes, and the following data were collected: (1) participant characteristics (demographic, socioeconomic, and work-related aspects) using a pre-coded questionnaire; (2) physical activity level using the IPAQ; and (3) musculoskeletal symptoms using the Nordic questionnaire. Descriptive, bivariate, and Poisson regression analyses were performed. The prevalence of neck pain was 20.3% (95% CI 17.3-23.7). The adjusted analyses showed that individuals who were widowers or separated (PR=2.26; 1.42-5.88), had a low income (PR=1.32; 1.22-6.27) or low educational level (PR=1.83; 1.02-5.26), worked while sitting and leaning (PR=1.55; 1.08-2.40), and who reported having two or more diseases (PR=1.71; 1.55-6.31) remained associated with neck pain. This study reveals the high prevalence of neck pain and remarkable association with widowed/separated people who have low income and low educational level, who perform their occupational activities in sitting and leaning positions, and who reported having two or more diseases. Knowledge of these risk factors will contribute to the development of forms of assistance in which neck pain can be prevented and better managed.

    Hyperhidrosis is defined as excessive sweating which can be primary or secondary. Data about the prevalence of primary hyperhidrosis are scarce for northern Europe. Our aim was to investigate the prevalence of hyperhidrosis focusing on its primary form and describe the quality of life impairments for the affected individuals. Five thousand random individuals aged 18-60 years in Sweden were investigated. The individuals' addresses were obtained from Statens personadressregister, SPAR, which includes all persons who are registered as resident in Sweden. A validated questionnaire regarding hyperhidrosis including the Hyperhidrosis Disease Severity Scale (HDSS) and 36-item Short Form (SF-36) health survey was sent to each individual. The participants were asked to return the coded questionnaire within 1 week. A total of 1,353 individuals (564 male, 747 female and 42 with unspecified gender) with a mean age of 43.1 ± 11.2 years responded. The prevalence of primary hyperhidrosis was 5.5%, and severe primary hyperhidrosis (HDSS 3-4 points) occurred in 1.4%. Secondary hyperhidrosis was observed in 14.8% of the participants. Our SF-36 results showed that secondary hyperhidrosis causes a significant (p hyperhidrosis impairs primarily the mental health (p Hyperhidrosis affects individuals in adolescence as a focal form while occurring as a generalised form with increasing age. Further, the prevalence of primary hyperhidrosis described in our study is comparable to other studies from the western hemisphere. While secondary, generalised hyperhidrosis impairs both physical and mental aspects of life, primary hyperhidrosis, with the exception of severe cases, mainly affects the mental health. © 2016 S.

    Childhood sleepwalking and sleep terrors are 2 parasomnias with a risk of serious injury for which familial aggregation has been shown. To assess the prevalence of sleepwalking and sleep terrors during childhood; to investigate the link between early sleep terrors and sleepwalking later in childhood; and to evaluate the degree of association between parental history of sleepwalking and presence of somnambulism and sleep terrors in children. Sleep data from a large prospective longitudinal cohort (the Quebec Longitudinal Study of Child Development) of 1940 children born in 1997 and 1998 in the province were studied from March 1999 to March 2011. Prevalence of sleep terrors and sleepwalking was assessed yearly from ages 1 1/2 and 2 1/2 years, respectively, to age 13 years through a questionnaire completed by the mother. Parental history of sleepwalking was also queried. The peak of prevalence was observed at 1 1/2 years for sleep terrors (34.4% of children; 95% CI, 32.3%-36.5%) and at age 10 years for sleepwalking (13.4%; 95% CI, 11.3%-15.5%). As many as one-third of the children who had early childhood sleep terrors developed sleepwalking later in childhood. The prevalence of childhood sleepwalking increases with the degree of parental history of sleepwalking: 22.5% (95% CI, 19.2%-25.8%) for children without a parental history of sleepwalking, 47.4% (95% CI, 38.9%-55.9%) for children who had 1 parent with a history of sleepwalking, and 61.5% (95% CI, 42.8%-80.2%) for children whose mother and father had a history of sleepwalking. Moreover, parental history of sleepwalking predicted the incidence of sleep terrors in children as well as the persistent nature of sleep terrors. These findings substantiate the strong familial aggregation for the 2 parasomnias and lend support to the notion that sleepwalking and sleep terrors represent 2 manifestations of the same underlying pathophysiological entity.

    The metabolic syndrome (MS) is defined by the clustering of a number of cardiovascular risk factors. The aims of the present study were to estimate the prevalence of MS in Madrid (Spain) by 2 definitions and to investigate its relationship with several sociodemographic factors and C-reactive protein (CRP) levels. This was a cross-sectional population study, and participants were 1344 subjects aged 31 to 70 years. Clinical evaluation included data on sociodemographic and cardiovascular background, physical examination, fasting glucose, triglycerides, and high-density lipoprotein cholesterol. The CRP levels were determined in a subgroup of 843 subjects. The diagnosis of MS was made according to the 2005 Adult Treatment Panel III (ATP III) and International Diabetes Federation (IDF) definitions. The age- and sex-adjusted prevalence of MS was 24.6% (95% confidence interval [CI], 22.3%-26.9%) using the ATP III definition and 30.9% (95% CI, 28.4%-33.3%) using the International Diabetes Federation definition. The overall agreement rate was 91.5% (kappa = 0.80; 95% CI, 0.76-0.83). Prevalence figures by both definitions were higher in men than in women and increased with age. Male sex, older age, low educational level, and physical inactivity were all determinants of ATP III-defined MS. The presence of MS or any of its components was associated with high CRP levels. In a logistic regression analysis, low educational level and waist circumference were the best predictors for high CRP level. The prevalence of MS in the Madrid region is one of the highest in Europe and confirms the strong Spanish regional variability in this syndrome frequency. Some sociodemographic and lifestyle factors, particularly educational level, are predictors for MS and high CRP levels.

    Background: Salmonella is an important zoonotic pathogen and its prevalence in the chicken meat and eggs acts as a continuous threat to human population. The current studies covering a time period of three years, was carried out to report the isolation of salmonellae from the chicken tissues, eggs and feed ingredient. Methods: A total of 1747 random samples from twelve different sources and 56 locations in Islamabad and Northern Punjab area of Pakistan, were screened for isolation studies according to the already published established protocols. Results: The analysis of 1747 random samples comprising of 1069 (61.19%) chicken organs and 678 (38.81%) allied sources including eggs and feed ingredients, showed that a total of 162 (9.27%) were positive for salmonellae. Isolation prevalence in various chicken organs and allied sources was 86 (8.04%) and 76 (11.20%) respectively. The maximum isolation prevalence was recorded in meat meal (19.35%), followed by fish meal (17.54%), hatchery fluff (14.63%), livers (13.17%), poultry litter (10.89%), and eggs (9.64%). The range of Salmonella isolated varied from 19.35% to 4.72% in various organs and allied sources. Conclusions: Our findings highlighted a potential public health hazard and emphasized the significance of continuous surveillance system in the country to understand the ever changing epidemiological pattern of Salmonella serovers. The endemic prevalence of various serovars can cause outbreaks of human salmonellosis due to the consumption of contaminated meat and eggs as has already been reported worldwide. (author)

    To calculate the prevalence of all vitreomacular interface (VMI) disorders and stratify according to age, sex and (pre)diabetes status. The presence of VMI disorders was assessed in 2660 participants aged between 40 and 75 years from The Maastricht Study who had a gradable macular spectral-domain optical coherence tomography (SD-OCT) volume scan in at least one eye [mean 59.7 ± 8.2 years, 50.2% men, 1531 normal glucose metabolism (NGM), 401 prediabetes, 728 type 2 diabetes (DM2, oversampled)]. A stratified and multivariable logistic regression analysis was used. The prevalence of the different VMI disorders for individuals with NGM, prediabetes and DM2 was, respectively, 5.7%, 6% and 6.7% for epiretinal membranes; 6%, 9.6% and 6.8% for vitreomacular traction; 1.1%, 0.7% and 0.3% for lamellar macular holes; 0.1%, 0% and 0% for pseudoholes; 1.1%, 1.9% and 5.5% for macular cysts. None of the participants was diagnosed with a macular hole. The prevalence of epiretinal membranes, vitreomacular traction and macular cysts was higher with age (p women (p DM2 is positively associated [OR = 3.9 (95% CI 2.11-7.22, p < 0.001)] with macular cysts and negatively associated with lamellar macular holes [OR = 0.2 (95% CI 0.04-0.9, p = 0.036)] after adjustment for age and sex. The calculated prevalence of VMI disorders was 15.9%. The calculated prevalence of VMI disorders in individuals aged between 40 and 75 years is 15.9%. The prevalence depends on age, sex and glucose metabolism status for several types of VMI disorders. © 2018 The Authors.

    Full Text Available Abstract Background High blood pressure (HBP is an increasing public health issue for developing countries. HBP is an important contributing factor to many non-communicable diseases that were until very recently thought to be rare in developing countries. There is not enough evidence on its burden and risk factors in Africa. We report in this study on the prevalence and factors associated with HBP in the adult and active population of Burkina Faso from a nationally representative sample. Methods We conducted a secondary analysis of data from the World Health Organization (WHO Stepwise approach to Surveillance(STEPS survey on the prevalence of major risk factors for non-communicable diseases in Burkina Faso. This survey was conducted between September 26 and November 18, 2013 and involved a nationally representative sample of 4,800 adults aged 25 to 64 years. The risk factors were identified using a binary logistic regression in STATA Version 13.1 software. Results The analysis was conducted on a sample of 4629 participants of whom 72.18% lived in rural areas. The overall prevalence of hypertension in Burkina Faso was 18% (95% CI: 16.19%–19.96%. In urban areas the prevalence was 24.81% (95% CI 20.21%–30.07% and 15.37% (95% CI 13.67%–17.24% in rural areas. Increased Body Mass Index (BMI and older age were consistently associated with higher odds of HBP in both residential areas. In addition, being of male sex, fat intake, family history of HBP and low level of HDL cholesterol were significantly associated with increased odds of HBP in rural residents. Conclusion The prevalence of hypertension is high in Burkina Faso with roughly one person in five affected. There is a predominant burden in urban areas with prevalence of ten-point percent higher compared to rural area. Modifiable risk factors should be targeted with appropriate and effective strategies to curb the rising burden of hypertension and its consequences.

    New research on the vermiform appendix has shed light on its function. In further understanding the function of the appendix, this information should not negatively impact the clinical judgment in the event of appendicitis. Although the appendix and its pathology have been noted for centuries, it still presents a challenge in the operating room. The most common emergency surgical procedure performed is an appendectomy. Its highly variable position within the abdomen can cause confusion for clinicians. However, improved imaging modalities have heightened the physician's ability to diagnose disease of this organ. This article reviews germane literature regarding the human vermiform appendix. Copyright © 2013 Wiley Periodicals, Inc.

    Full Text Available BACKGROUND Headache or cephalgia is one of the commonest symptoms causing pain in head above eyes or the ears, behind the head in the occipital region or in the back of the upper neck causing pain as well as disability to an individual. WHO reports around 47% of adults worldwide will have experienced headache in the last year. Headache maybe primary or secondary. Tension headache is more common type of primary headache. Almost, 90% of adults have tension headache and it is more common in females than males. Migraine headache is third most prevalent disorder worldwide and ranked as seventh highest cause of disability. Migraine headaches are the second most common type of primary headaches, whereas cluster headache, a relatively uncommon type of primary headache affecting less than 1 in every 1000 adults. 1 Many people suffer from mixed headache disorder in which tension headache or secondary headache may trigger migraine. Headache on 15 or more days in every month affects 1.7-4% of the world adult population. Hospital-based studies of migraine shows India is home over 16% of world inhabitants suffering from migraine. MATERIALS AND METHODS In our study, total screening of 1200 cases was done with headache symptomatology reported to Eye OPD directly as well as referred from ENT, Medical, NeuroMedical, Surgical, Neurosurgical, Psychiatry, Orthopaedics and Trauma Ward. A detailed clinical examination and ophthalmological examination was done in 1200 cases. RESULTS Sexual prevalence in our study indicated female with increased prevalence of 46.67% compared to male of 36%. Among 30 cases of migrainous headache with or without aura, the sexual prevalence in our study has female-to-male ratio as 2:1 (female - 20 cases and male - 10 cases. No cluster headache disorder was reported in our study. Among the tension headache presented with ocular manifestations like association of the refractive error, redness, burning sensation, the female prevalence among

    2013-05-01

    Full Text Available Summary: Background: Chronic obstructive pulmonary disease (COPD has been a leading cause of morbidity and mortality worldwide, over the years. In 1995, the implementation of a respiratory function survey seemed to be an adequate way to draw attention to neglected respiratory symptoms and increase the awareness of spirometry surveys. By 2002 there were new consensual guidelines in place and the awareness that prevalence of COPD depended on the criteria used for airway obstruction definition. The purpose of this study is to revisit the two studies and to turn public some of the data and respective methodologies. Methods: From Pneumobil Study database of 12,684 subjects, only the individuals with 40+ years old (n = 9.061 were selected. The 2002 Study included a randomized representative sample of 1384 individuals with 35–69 years old. Results: The prevalence of COPD was 8.96% in Pneumobil and 5.34% in the 2002 Study. In both studies, presence of COPD was greater in males and there was a positive association between presence of COPD and older age groups. Smokers and ex-smokers showed a higher proportion of cases of COPD. Conclusions: Prevalence in Portugal is lower than in other European countries. This may be related to lower smokers’ prevalence. Globally, the most important risk factors associated with COPD were age over 60 years, male gender and smoking exposure. All aspects and limitations regarding different recruitment methodologies and different criteria for defining COPD cases highlight the need of a standardized method to evaluate COPD prevalence and associated risks factors, whose results can be compared across countries, as it is the case of BOLD project.

    Full Text Available Background: Increasing life expectancy around the world, an outstanding achievement of our century, has brought with it new public health challenges. India is the second most populous country in the world, with over 72 million inhabitants above 60 years of age as of 2001. The life expectancy in India increased from 32 years in 1947 to over 66 years in 2010, with 8.0% of the population now reaching over 60 years of age. Few studies in India target the health, especially mental health, of this geriatric population. This study aims to estimate the current prevalence of psychiatric disorders in the geriatric population of the rural area of Singanodi,Karnataka, India.Methods: This cross sectional, epidemiological, community-based study was conducted in a rural health training area of Singanodi, Raichur District, Karnataka, India.The General Health Questionnaire-12, Mini Mental State Examination, and Geriatric Depression Scale were administered to 366 participants. Chi square tests with Yates correction were utilized for statistical analysis using SPSS 19.0 software.Results:We found that 33.9% of the geriatric population in the selected province were above the threshold for mental illness based on the GHQ-12 questionnaire. Females had a higher prevalence of mental disorder at 77.6% (152 out of 196 as compared to males who had a prevalence of 42.4% (72 out of 170. The most common psychiatric disorder was depression (21.9%, and generalized anxiety was present in 10.7% of the study population. Prevalence of cognitive impairment was 16.3%, with a significantly higher percentage of  affected individuals in 80+ age group.Conclusion: Mental disorders are common among elderly people, but they are not well documented in rural India. The assessment of psychiatric disorder prevalence will help strengthen psycho-geriatric services and thus improve the quality of life of the elderly.  A system that ensures comprehensive health care will have to be developed for

    Few population-based studies of cerebral palsy have been done in low-income and middle-income countries. We aimed to examine cerebral palsy prevalence and subtypes, functional impairments, and presumed time of injury in children in Uganda. In this population-based study, we used a nested, three-stage, cross-sectional method (Iganga-Mayuge Health and Demographic Surveillance System [HDSS]) to screen for cerebral palsy in children aged 2-17 years in a rural eastern Uganda district. A specialist team confirmed the diagnosis and determined the subtype, motor function (according to the Gross Motor Function Classification System [GMFCS]), and possible time of brain injury for each child. Triangulation and interviews with key village informants were used to identify additional cases of suspected cerebral palsy. We estimated crude and adjusted cerebral palsy prevalence. We did χ 2 analyses to examine differences between the group screened at stage 1 and the entire population and regression analyses to investigate associations between the number of cases and age, GMFCS level, subtype, and time of injury. We used data from the March 1, 2015, to June 30, 2015, surveillance round of the Iganga-Mayuge HDSS. 31 756 children were screened for cerebral palsy, which was confirmed in 86 (19%) of 442 children who screened positive in the first screening stage. The crude cerebral palsy prevalence was 2·7 (95% CI 2·2-3·3) per 1000 children, and prevalence increased to 2·9 (2·4-3·6) per 1000 children after adjustment for attrition. The prevalence was lower in older (8-17 years) than in younger (cerebral palsy was the most common subtype (45 [46%] of 97 children) followed by bilateral cerebral palsy (39 [40%] of 97 children). 14 (27%) of 51 children aged 2-7 years had severe cerebral palsy (GMFCS levels 4-5) compared with only five (12%) of 42 children aged 8-17 years. Few children (two [2%] of 97) diagnosed with cerebral palsy were born preterm. Post-neonatal events were the

    Splanchnic vein thrombosis (SVT) may be negatively associated with the prognosis of pancreatitis. We performed a systematic review and meta-analysis of literatures to explore the prevalence of SVT in pancreatitis. All observational studies regarding the prevalence of SVT in pancreatitis were identified via PubMed and EMBASE databases. The prevalence of SVT was pooled in the total of patients with pancreatitis. And it was also pooled in the subgroup analyses according to the stage and causes of pancreatitis, location of SVT, and regions where the studies were performed. After the review of 714 studies, 44 studies fulfilled the inclusion criteria. Meta-analyses showed a pooled prevalence of SVT of 13.6% in pancreatitis. According to the stage of pancreatitis, the pooled prevalence of SVT was 16.6% and 11.6% in patients with acute and chronic pancreatitis, respectively. According to the causes of pancreatitis, the pooled prevalence of SVT was 12.2% and 14.6% in patients with hereditary and autoimmune pancreatitis. According to the location of SVT, the pooled prevalence of portal vein, splenic vein, and mesenteric vein thrombosis was 6.2%, 11.2%, and 2.7% in pancreatitis. The prevalence of SVT in pancreatitis was 16.9%, 11.5%, and 8.5% in Europe, America, and Asia, respectively.

    Smoking and radon both cause lung cancer, and together the risk is significantly higher. UK public health campaigns continue to reduce smoking prevalence, and other initiatives identify houses with raised radon (radon-222) levels and encourage remedial action. Smoking prevalence and radon levels in the UK have been mapped at Primary Care Trust level. This paper extends that work, using a commercial socio-demographic database to estimate smoking prevalence at the postcode sector level, and to predict the population characteristics at postcode sector level for 87 postcode sectors in Northamptonshire. Likely smoking prevalence in each postcode sector is then modelled from estimates of the smoking prevalence in the different socio-economic groups used by the database. Mapping estimated smoking prevalence, radon potential and average lung cancer incidence for each postcode sector suggested that there was little correlation between smoking prevalence and radon levels, as radon potential was generally lower in urban areas in Northamptonshire, where the estimates of smoking prevalence were highest. However, the analysis demonstrated some sectors where both radon potential and smoking prevalence were moderately raised. This study showed the potential of this methodology to map estimated smoking prevalence and radon levels to inform locally targeted public health campaigns to reduce lung cancer incidence. - Highlights: • We use a commercial socio-demographic database to estimate smoking prevalence in small areas in Northamptonshire, UK. • We map the estimated smoking prevalence and average domestic radon levels in these small areas. • We estimate annual average lung cancer incidence in these small areas. • The methodology is useful to evaluate and plan localised public health campaigns to reduce lung cancer incidence.

    The aim of this study was to evaluate the prevalence of posterior crossbite among children whose pacifier-sucking habit persisted until different ages. Children aged 3 to 6 years were randomly selected from public preschools in São Paulo, SP, Brazil. Their mothers were asked to complete a questionnaire on non-nutritive sucking behaviors. The sample consisted of 366 children assigned to 2 groups: control (n = 96) and pacifier users (n = 270). Pacifier users were further assigned to 3 subgroups, according to the age of habit persistence: P1 - until 2 years of age; P2 - between 2 and 4 years of age; and P3 - between 4 and 6 years of age. One dentist assessed the children for occlusal relationships through clinical examination. Associations between the age interval of habit discontinuation and the prevalence of posterior crossbite were analyzed using the chi-square test (p pacifier users (20.4%), compared to control children (5.2%), p pacifier users (9.8% versus 3.6%). Functional posterior crossbites were diagnosed in 3.1% of the control children and 7% of the pacifier users. The frequencies of posterior crossbite were notably high for children in the 3 pacifier subgroups, P1, P2, and P3, corresponding to 17.2%, 16.9%, and 27.3%, respectively. The high prevalence of posterior crossbite may be associated with pacifier-sucking habits that persisted after 2 years of age.

    A subset of people with co-occurring substance use and mental disorders require coordinated support from health, social welfare and justice agencies to achieve diversion from homelessness, criminal recidivism and further health and social harms. Integrated models of care are typically concentrated in large urban centres. The present study aimed to empirically measure the prevalence and distribution of complex co-occurring disorders (CCD) in a large geographic region that includes urban as well as rural and remote settings. Linked data were examined in a population of roughly 3.7 million adults. Inclusion criteria for the CCD subpopulation were: physician diagnosed substance use and mental disorders; psychiatric hospitalisation; shelter assistance; and criminal convictions. Prevalence per 100 000 was calculated in 91 small areas representing urban, rural and remote settings. 2202 individuals met our inclusion criteria for CCD. Participants had high rates of hospitalisation (8.2 admissions), criminal convictions (8.6 sentences) and social assistance payments (over $36 000 CDN) in the past 5 years. There was wide variability in the geographic distribution of people with CCD, with high prevalence rates in rural and remote settings. People with CCD are not restricted to areas with large populations or to urban settings. The highest per capita rates of CCD were observed in relatively remote locations, where mental health and substance use services are typically in limited supply. Empirically supported interventions must be adapted to meet the needs of people living outside of urban settings with high rates of CCD.

    Background Polycystic ovary syndrome (PCOS) is a common condition estimated to affect 5.61% of Chinese women of reproductive age, but little is known about the prevalence and predictors in Chinese PCOS patients. This study aimed to determine the prevalence and predictors of the metabolic abnormalities in Chinese women with and without PCOS. Methods A large-scale national epidemiological investigation was conducted in reproductive age women (19 to 45 years) across China. 833 reproductive aged PCOS women, who participated in the healthcare screening, were recruited from ten provinces in China. Clinical history, ultrasonographic exam (ovarian follicle), hormonal and metabolic parameters were the main outcome measures. Results The prevalence of metabolic syndrome (MetS) as compared in PCOS and non-PCOS women from community were 18.2% vs 14.7%, and IR (insulin resistance) were 14.2% vs 9.3% (p PCOS than in non-PCOS groups. Using multivariate logistic regression, central obesity and FAI were risk factors, while SHBG was a protective factor on the occurrence of Mets and IR in PCOS women (OR: 1.132, 1.105 and 0.995). Conclusions The risk factors of the metabolic syndrome and insulin resistance were BMI and FAI for PCOS women, respectively. The decrease of SHBG level was also a risk factor for insulin resistance in both PCOS and metabolic disturbance. PMID:25223276

    Assessment of lipid profile parameters has been considered a cornerstone in classifying individuals and populations at risk for cardiovascular disease. Recently, however, preliminary data have raised the possibility of seasonal variations in these parameters, which may cause under- or overestimation. Biological rhythms and seasonal variation of lipid profile was investigated in 227 359 consecutive individuals who underwent health checkups in primary care centers between 2008 and 2010. Plasma low-density lipoprotein cholesterol (LDL-C) >130 mg/dL was 8% more prevalent during winter than summer, with a larger difference among women and middle-aged adults (p 150 mg/dL were respectively 9% and 5% more prevalent during the summer (p < 0.001). Variation amplitude was 3.4 ± 0.3 mg/dL for HDL-C (p = 0.005), 7 ± 2 mg/dL for LDL-C (p = 0.047), and 12 ± 9 mg/dL for TG (p = 0.058). Based on a large population sample, this study confirms the existence of biological rhythms and seasonal variation in lipid profile. This finding must be particularly accounted for in cross-sectional analyses of relative risk, prevalence, or the rate of goal achievement for lipid parameters.

    Purpose To determine prevalence and associations of incomplete posterior vitreous detachment (PVD). Methods The population-based cross-sectional Beijing Eye Study 2011 included 3468 individuals with a mean age of 64.6±9.8 years (range: 50–93 years). A detailed ophthalmic examination was performed including spectral-domain optical coherence tomography (SD-OCT). Incomplete PVD was differentiated into type 1 (shallow PVD with circular perifoveal vitreous attachment), type 2 (PVD reaching fovea but not foveola), type 3 (shallow PVD with pinpoint vitreous attachment at the foveola), and type 4 (PVD completely detached from the macula, attached to the optic disc). Results An incomplete PVD was detected in 3948 eyes (prevalence: 60.5±0.6%; 95% Confidence Interval (CI): 59.3%,61.7%) of 2198 subjects (67.1±0.8%;95%CI: 65.6%,68.7%). Type 1 PVD was seen in 3090 (78.3%) eyes, type 2 PVD in 504 (12.8%) eyes, type 3 PVD in 70 (1.8%) eyes, and type 4 PVD in 284 (7.2%) eyes. Prevalence of incomplete PVD was associated with younger age (PPVD was associated with higher age (PPVD (detected in 67.1% subjects) was associated with younger age, male gender, rural region of habitation, larger corneal diameter, better best corrected visual acuity and hyperopic refractive error.

    This retrospective study aimed to investigate the prevalence of pressure ulcers (PUs) in older patients with advanced dementia versus older patients without dementia but with other comorbidities, such as diabetes, ischaemic heart disease and chronic renal failure. PUs were thought to be more prevalent and to present a higher risk of mortality in patients with dementia. PUs were assessed on admission using the European Pressure Ulcer Advisory Panel (EPUAP) staging system. Patients were classified as either with or without dementia according to Reisberg's functional assessment staging test (FAST). The prevalence of PUs and the survival rates were analysed and compared in both groups. The combined effect of PUs and dementia on survival was assessed using the Cox proportional hazard model. The median survival rate of patients with PUs and dementia was 63 days, significantly lower than in patients with PUs without dementia 117 days. Both groups had similar other comorbidities. These findings underscore the requirement for geriatricians and health professionals to be more vigilant in examining PUs as dementia progresses.

    To assess the prevalence and distribution patterns of multimorbidity among urban older adults in Burkina Faso. Cross-sectional study among community-dwelling elderly people aged ≥60 in Bobo-Dioulasso. We performed interviews, clinical examination and medical record review. Multimorbidity was defined as co-occurrence of at least two chronic diseases in one person whether as a coincidence or not. The overall prevalence of multimorbidity among older adults was 65%. Age ≥70 was associated with multimorbidity in multivariate analysis: adjusted OR = 1.65, 95% CI (1.01-2.68, P = 0.04). The most common chronic diseases were hypertension (82%) 95% CI (78; 86), malnutrition (39%) 95% CI (34; 44), visual impairments (28%) 95% CI (24; 33) and diabetes mellitus (27%) 95% CI (22; 31). Those aged ≥70 had significantly more malnutrition (50% vs. 31%, P = 0.0003) and osteoarthritis (8% vs. 3%, P = 0.01) than those aged 60-69. The high prevalence of multimorbidity requires a reorganization of healthcare systems in sub-Saharan Africa, especially in Burkina Faso. Interventions and care guidelines usually focused on individual diseases should be improved to better reflect this reality. © 2014 John Wiley & Sons Ltd.

    This study investigates the prevalence of psychological distress and stressors in the work environment as prospective predictors of distress, among employees in the offshore petroleum industry. Correlation and logistic regression analyses were employed to examine longitudinal relationships between stressors and distress in a randomly drawn sample of 741 employees from the Norwegian petroleum offshore industry. Time lag between baseline and follow-up was 6 months. Work environment stressors included safety factors, leadership, and job characteristics. The prevalence of psychological distress was 9 % at baseline and 8 % at follow-up. All investigated work environment factors correlated with subsequent distress. In bivariate logistic regression analyses, caseness of distress was predicted by baseline distress, near miss accidents, risk perception, poor safety climate, tyrannical leadership, laissez-faire leadership, job demands, and workplace bullying. After adjustment for baseline distress, control variables, and other predictors, laissez-faire leadership (OR = 1.69; 95 % CI: 1.12-2.54) and exposure to bullying (OR = 1.49; 95 % CI: 1.07-2.10) emerged as the most robust predictors of subsequent distress. The findings show that the prevalence of psychological distress is lower among offshore employees than in the general population. Although offshore workers operate in a physically challenging context, their mental health is mainly influenced by stressors in the psychosocial work environment. This highlights the importance of developing and implementing psychosocial safety interventions within the offshore industry.

However, this growth can be attenuated if effective preventive strategies are adopted. Purpose: To provide the first national population-based prevalence of CHD and to describe the profile of Lebanese adults with prevalent CHD. Methods: We carried out a cross-sectional study using a multistage cluster sample across Lebanon. We interviewed residents aged 40 years and older using a questionnaire that captured the presence of CHDs and their risk factors (RFs. Results: Our study showed that 13.4% of the Lebanese population aged ≥40 years suffer from a prevalent CHD. CHD seemed to appear more prematurely than in developed countries, and males seemed to be more subject to CHD than females until a certain age. CHD was associated with older age, male sex, a lower economic situation, hypercholesterolemia, hypertension, having a family history of premature cardiovascular diseases, and suffering from diabetes. However, smoking and waist circumference did not seem to have an independent effect on CHD, but rather an effect

    Fabry disease is a treatable cause of chronic kidney disease (CKD) characterized by a genetic deficiency of α-galactosidase A. European Renal Best Practice (ERBP) recommends screening for Fabry disease in CKD patients. However, this is based on expert opinion and there are no reports of the prevalence of Fabry disease in stage 1-5 CKD. Hence, we investigated the prevalence of Fabry disease in CKD patients not receiving renal replacement therapy. This prospective study assessed α-galactosidase activity in dried blood spots in 313 stage 1-5 CKD patients, 167 males, between ages of 18-70 years whose etiology of CKD was unknown and were not receiving renal replacement therapy. The diagnosis was confirmed by GLA gene mutation analysis. Three (all males) of 313 CKD patients (0.95%) were diagnosed of Fabry disease, for a prevalence in males of 1.80%. Family screening identified 8 aditional Fabry patients with CKD. Of a total of 11 Fabry patients, 7 were male and started enzyme replacement therapy and 4 were female. The most frequent manifestations in male patients were fatigue (100%), tinnitus, vertigo, acroparesthesia, hypohidrosis, cornea verticillata and angiokeratoma (all 85%), heat intolerance (71%), and abdominal pain (57%). The most frequent manifestations in female patients were fatigue and cornea verticillata (50%), and tinnitus, vertigo and angiokeratoma (25%). Three patients had severe episodic abdominal pain attacks and proteinuria, and were misdiagnosed as familial Mediterranean fever. The prevalence of Fabry disease in selected CKD patients is in the range found among renal replacement therapy patients, but the disease is diagnosed at an earlier, treatable stage. These data support the ERBP recommendation to screen for Fabry disease in patients with CKD of unknown origin. © 2016 The Author(s) Published by S. Karger AG, Basel.

    2012-02-15

    BACKGROUND: Surveillance of Clostridium difficile infection (CDI) is an essential component of a CDI preventative programme. AIMS: The aim of this study was to evaluate two methods of CDI surveillance. METHODS: Prevalence of CDI, antibiotic use and associated co-morbidity was assessed weekly on two wards over 6 weeks. In addition, CDI incidence surveillance was performed on all new CDI cases over a 13-week period. Cases were assessed for CDI risk factors, disease severity, response to treatment and outcome at 6 months. RESULTS: Clostridium difficile infection prevalence was 3.5% (range 2.9-6.1%) on the medical ward and 1.1% (range 0-3.5%) on the surgical ward. Patients on the medical ward were older and more likely to be colonised with MRSA; however, recent antibiotic use was more prevalent among surgical patients. Sixty-one new CDI cases were audited. Patients were elderly (mean age 71 years) with significant co-morbidity (median age adjusted Charlson co-morbidity score 5). CDI ribotypes included 027 (29 cases) 078 (5) and 106 (4). Eight patients developed severe CDI, seven due to 027. Antibiotic use was common with 56% receiving three or more antibiotics in the preceding 8 weeks. Twenty-four patients had died at 6 months, five due to CDI. CONCLUSION: Clostridium difficile infection prevalence gives a broad overview of CDI and points to areas that require more detailed surveillance and requires little time. However, patient-based CDI incidence surveillance provides a more useful analysis of CDI risk factors, disease and outcome for planning preventative programmes and focusing antibiotic stewardship efforts.

    Full Text Available PURPOSE: To evaluate the prevalence and associated factors of steep cornea/keratoconus in the adult Chinese population. METHODS: The population-based Beijing Eye Study 2011 included 3468 individuals with a mean age of 64.6±9.8 years (range: 50-93 years. A detailed ophthalmic examination was performed including optical low-coherence reflectometry. Steep cornea/keratoconus were defined as an anterior corneal refractive power exceeding 48 diopters. RESULTS: Mean refractive power of the cornea was 43.16±1.45 diopters (range: 36.51 to 48.46 diopters; flattest meridian and 43.98±1.52 diopters (range: 37.00 to 52.88 diopters; steepest meridian. A steep cornea/keratoconus defined as corneal refractive power of ≥48 diopters and ≥49 diopters was detected in 27 subjects (prevalence rate: 0.9±0.2% and 6 (0.2± 0.1% subjects, respectively. Presence of steep cornea/keratoconus was associated with shorter axial length (P<0.001, smaller interpupillary distance (P = 0.038, lower best corrected visual acuity (P = 0.021, higher cylindrical refractive error (P<0.001 and more myopic refractive error (P<0.001. It was not significantly associated with gender, body height, psychic depression, cognitive function, blood concentrations of glucose, lipids, creatinine and C-reactive protein, blood pressure and quality of life score, nor with intraocular pressure, dry eye feeling, and lens thickness. CONCLUSIONS: A steep cornea/keratoconus defined as corneal refractive power of 48+ diopters has a prevalence of 0.9±0.2% among Chinese aged 50 years and above. Its prevalence was significantly associated with the ocular parameters of shorter axial length, smaller interpupillary distance, higher cylindrical and myopic refractive error and lower best corrected visual acuity, however, with none of the systemic parameters tested.

    To investigate the prevalence and associated factors of kidney stones among adults in China. A nationwide cross-sectional survey was conducted among individuals aged ≥18 years across China, from May 2013 to July 2014. Participants underwent urinary tract ultrasonographic examinations, completed pre-designed and standardised questionnaires, and provided blood and urine samples for analysis. Kidney stones were defined as particles of ≥4 mm. Prevalence was defined as the proportion of participants with kidney stones and binary logistic regression was used to estimate the associated factors. A total of 12 570 individuals (45.2% men) with a mean (sd, range) age of 48.8 (15.3, 18-96) years were selected and invited to participate in the study. In all, 9310 (40.7% men) participants completed the investigation, with a response rate of 74.1%. The prevalence of kidney stones was 6.4% [95% confidence interval (CI) 5.9, 6.9], and the age- and sex-adjusted prevalence was 5.8% (95% CI 5.3, 6.3; 6.5% in men and 5.1% in women). Binary logistic regression analysis showed that male gender, rural residency, age, family history of urinary stones, concurrent diabetes mellitus and hyperuricaemia, increased consumption of meat, and excessive sweating were all statistically significantly associated with a greater risk of kidney stones. By contrast, consumption of more tea, legumes, and fermented vinegar was statistically significantly associated with a lesser risk of kidney stone formation. Kidney stones are common among Chinese adults, with about one in 17 adults affected currently. Some Chinese dietary habits may lower the risk of kidney stone formation. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

    To assess the prevalence and types of glaucoma in an Asian Malay population. The Singapore Malay Eye Study is a population-based, cross-sectional survey that examined 3280 (78.7% response) persons aged 40 to 80 years. Participants underwent a standardized clinical examination including slit-lamp biomicroscopy, Goldmann applanation tonometry, and dilated optic disc assessment. Participants who were suspected to have glaucoma also underwent visual field examination (24-2 SITA standard, Humphrey Visual Field Analyzer II), gonioscopy, and repeat applanation tonometry. Glaucoma was defined according to International Society for Geographical and Epidemiologic Ophthalmology criteria. Of the 3280 participants, 150 (4.6%) had diagnosed glaucoma, giving an age- and sex-standardized prevalence of 3.4% (95% confidence interval [CI], 3.3%-3.5%). The age- and sex-standardized prevalence of primary open-angle glaucoma was 2.5% (95% CI, 2.4%-2.6%), primary angle-closure glaucoma 0.12% (95% CI, 0.10%-0.14%), and secondary glaucoma 0.61% (95% CI, 0.59%-0.63%). Of the 150 glaucoma cases, only 12 (8%) had a previous known history of glaucoma. Twenty-seven (18%) eyes had low vision (based on best corrected visual acuity logarithm of the minimal angle of resolution [logMAR] >0.30 to /=1.00). The prevalence of glaucoma among Malay persons 40 years of age and older in Singapore is 3.4%, comparable to ethnic Chinese people in Singapore and other racial/ethnic groups in Asia. As in Chinese, Caucasians, and African people, primary open-angle glaucoma was the main form of glaucoma in this population. More than 90% of glaucoma cases were previously undetected.

    BACKGROUND Sunlight exposure is responsible for a large number of dermatological diseases. OBJECTIVE We estimated the prevalence of sunlight exposure and its associated factors in adults from southern Brazil in a cross-sectional, population-based study. METHODS We investigated a representative sample of individuals aged ≥ 20 years (n=3,136). Sunlight exposure and its associated factors were evaluated in two distinct situations: at leisure time and at work. The time period investigated ranged from December 2004 to March 2005, comprising 120 days of the highest ultraviolet index in the urban area of the city of Pelotas, in southern Brazil. The participants were asked about sunlight exposure for at least 20 minutes between 10 A.M. and 4 P.M. The analysis was stratified by sex, and sunlight exposure was grouped into five categories. RESULTS Among the 3,136 participants, prevalence of sunlight exposure at the beach was 32.8% (95% CI, 30.3 - 35.2) and 26.3% (95% CI, 24.2 28.3) among men and women, respectively. The prevalence at work was 39.8% (95% CI, 37.2 - 42.4) among men and 10.5% (95% CI, 9.1 - 12.0) among women. Age was inversely associated with sunlight exposure. Family income and achieved schooling were positively associated with sunlight exposure at leisure time and inversely associated with sunglight exposure at work. Self-reported skin color was not associated. Knowledge of any friend or relative who has been affected by skin cancer was positively associated with sunlight exposure among men at work. CONCLUSION Despite the media campaigns on the harmful effects of excessive sunlight exposure, we found a high prevalence of sunlight exposure during a period of high ultraviolet index. PMID:24068126

    Full Text Available Background Some previously published studies have suggested an inverse relationship between celiac disease and Helicobacter pylori, raising the possibility of the protective role Helicobacter pylori could have against celiac disease development. Nevertheless, this association is inconclusive. Objectives To determine the prevalence of Helicobacter pylori infection in celiac subjects. Methods Between January 2013 and June 2014, patients over 18 years old undergoing upper endoscopy who required both gastric and duodenal biopsies were included for analysis. Enrolled subjects were divided in two groups: those with a diagnosis of celiac disease and those without a celiac disease diagnosis. Helicobacter pylori infection prevalence was compared between groups. Among celiac patients, endoscopic markers of villous atrophy as well as histological damage severity were compared between those with and without Helicobacter pylori infection. Results Overall, 312 patients were enrolled. Seventy two of them had a diagnosis of celiac disease. Helicobacter pylori infection prevalence among celiac disease patients was 12.5%, compared to 30% in non-celiac patients [OR=0.33 (0.15-0.71]. There was not a significant difference in terms of the severity of villous atrophy in patients with Helicobacter pylori infection compared to those without it. There was a slight increase in the prevalence of endoscopic markers in those Helicobacter pylori-negative celiac subjects. Conclusion Helicobacter pylori infection seems to be less frequent in celiac patients; among those celiac subjects with concomitant Helicobacter pylori infection, histological damage degree and presence of endoscopic markers suggesting villous atrophy seem to be similar to those without Helicobacter pylori infection.

    The police personnel are special group of population that work for minimum 12 hours a day. They are at risk of various types of chronic morbidities. To determine the sociodemographic, chronic morbidity and health profile of police personnel of Vadodara district. It was a cross-sectional study conducted on the police force of Vadodara district, Gujarat, India. The present study was the outcome of health checkup camp for police personnel. Total 982 police personnel participated in the aforementioned study. Information regarding the sociodemographic profile, addiction to alcohol drinking, tobacco chewing or smoking, diagnosed chronic morbidities, BMI, blood sugar and history of exercise and yoga was collected. Data collected was entered into Microsoft Excel 2007 and analysed by using Epi-Info 7. Statistical methods used included frequencies and proportions for categorical data while range, mean and standard deviation were calculated for continuous data. For bivariate analysis, Chi-square test was used. In the study population, 95.10% were males. The prevalence of chronic morbidity, hypertension and diabetes were 9.5%, 5% and 2.6% respectively. About 47.05% had normal BMI and mean BMI was 24. The study revealed that 7.64% police personnel had the habit of smoking, 3.16% consumed alcohol whereas 24.03% consumed tobacco products. It was found that 138 (14.05%) were active in sports and 304 (30.95%) were actively involved in exercise while 44 (4.48%) were involved in yoga. The prevalence of hypertension (5%) and diabetes (2.6%) were low as compared to the general population (NFHS-4). This can be attributed to health consciousness prevalent among the population. A substantial number of study population were involved in sports, exercise and yoga.

    COPD is the third leading cause of death in the world and its global burden is predicted to increase further. Even though the prevalence of COPD is well studied, only few studies examined the incidence of COPD in a prospective and standardized manner. In a prospective population-based cohort study (Rotterdam Study) enrolling subjects aged ≥45, COPD was diagnosed based on a pre-bronchodilator obstructive spirometry (FEV1/FVC spirometry within the Rotterdam Study, cases were defined as having COPD diagnosed by a physician on the basis of clinical presentation and obstructive lung function measured by the general practitioner or respiratory physician. Incidence rates were calculated by dividing the number of incident cases by the total number of person years of subjects at risk. In this cohort of 14,619 participants, 1993 subjects with COPD were identified of whom 689 as prevalent ones and 1304 cases as incident ones. The overall incidence rate (IR) of COPD was 8.9/1000 person-years (PY); 95 % Confidence Interval (CI) 8.4-9.4. The IR was higher in males and in smokers. The proportion of female COPD participants without a history of smoking was 27.2 %, while this proportion was 7.3 % in males. The prevalence of COPD in the Rotterdam Study is 4.7 % and the overall incidence is approximately 9/1000 PY, with a higher incidence in males and in smokers. The proportion of never-smokers among female COPD cases is substantial.

    Six technical appendixes are presented that provide important supporting technical information for the study of the application of nondestructive measurements to spent-fuel storage. Each appendix addresses a particular technical subject in a reasonably self-contained fashion. Appendix A is a comparison of spent-fuel data predicted by reactor operators with measured data from reprocessors. This comparison indicates a rather high level of uncertainty in previous burnup calculations. Appendix B describes a series of nondestructive measurements at the GE-Morris Operation Spent-Fuel Storage Facility. This series of experiments successfully demonstrated a technique for reproducible positioning of fuel assemblies for nondestructive measurement. The experimental results indicate the importance of measuring the axial and angular burnup profiles of irradiated fuel assemblies for quantitative determination of spent-fuel parameters. Appendix C is a reasonably comprehensive bibliography of reports and symposia papers on spent-fuel nondestructive measurements to April 1981. Appendix D is a compendium of spent-fuel calculations that includes isotope production and depletion calculations using the EPRI-CINDER code, calculations of neutron and gamma-ray source terms, and correlations of these sources with burnup and plutonium content. Appendix E describes the pulsed-neutron technique and its potential application to spent-fuel measurements. Although not yet developed, the technique holds the promise of providing separate measurements of the uranium and plutonium fissile isotopes. Appendix F describes the experimental program and facilities at Los Alamos for the development of spent-fuel nondestructive measurement systems. Measurements are reported showing that the active neutron method is sensitive to the replacement of a single fuel rod with a dummy rod in an unirradiated uranium fuel assembly.

    Full Text Available BACKGROUND AND OBJECTIVE: Diabetes is a chronic disease that has a prolonged prediabetic phase. Indians develop diabetes 10 years earlier tha n other ethnic groups (mean age 42.5 years . 1 Diet, environment, genetics play a major role in development of diabetes. Complications of diabetes are directly proportional to the duration of diabetes and dysglycemia. Prediabetes is a condition is which glucose levels are high to be considered as normal, eventhough they do not meet the criteria for diabetes. 10% - 50% of prediabetics may develop diabetes in 3 - 10 year period. Components of prediabetes include either an isolated impai red fasting glucose or impaired glucose tolerance or both. Microvascular complications can begin is the prediabetic stage itself. Present study has been done to know the prevalence of microalbuminuria and retinopathy is prediabetic stage and correlation of both in prediabetics. MATERIALS AND METHODS: This study was conducted in a tertiary care Hospital from June 2013 to May 2014. Screening was done and patients recruited into the study after fulfilling the inclusion and exclusion criteria. American Diabetes Association Criteria 2 was used for screening and results were correlated using various parameters to know the prevalence of microalbuminuria and retinopathy in prediabetes. Data was analyzed using statistical package for social sciences(spss version 20.0 . RESULTS: In this study, 500 patients were screened for diabetes. 100 patients were included in the study. Prevalence of prediabetes was seen in 20% of patients screened. 19% of prediabetics had microalbuminuria and 8% had retinopathy. Association of both conditions was seen is 7% of patients. CONCLUSION: Diabetic Microvascular complications like retinopathy and nephropathy in the form of microalbuminuria starts even in the prediabetic stage in a significant number of patients.

Patients with all stages of lung cancer were included in this study. Demographic data of eligible patients were gathered. The Mini-International Neuropsychiatric Interview, Thai version 5.0.0 was used to identify MDD. The Thai version of the Personal Health Questionnaire Depression Scale was used to assess depression severity.Results: A total of 146 lung cancer patients from the outpatient clinic from July to December 2012 were approached. The 104 patients were included and analyzed in this study. Based on the Mini-International Neuropsychiatric Interview, 14.4% of them were defined as having MDD. Multiple linear regression analysis revealed that Chalder Fatigue Scale, Functional Assessment of Cancer Therapy – Lung, and Pittsburgh Sleep Quality Index scores were significantly correlated with MDD in lung cancer patients.Conclusion: The results suggest that MDD is more prevalent in lung cancer patients. In addition, fatigue, poor quality of life, and sleep disturbance may increase associated MDD. Because of the small sample size, further studies should be conducted to confirm these results.Keywords: lung cancer, major depressive disorder, prevalence

    Recognition that an older person has sarcopenia is important because this condition is linked to a range of adverse outcomes. Sarcopenia becomes increasingly common with age, and yet there are few data concerning its descriptive epidemiology in the very old (aged 85 years and above). Our aims were to describe risk factors for sarcopenia and estimate its prevalence and incidence in a British sample of the very old. We used data from two waves (2006/07 and 2009/10) of the Newcastle 85+ Study, a cohort born in 1921 and registered with a Newcastle/North Tyneside general practice. We assessed sarcopenia status using the European Working Group on Sarcopenia in Older People (EWGSOP) definition. Grip strength was measured using a Takei digital dynamometer (Takei Scientific Instruments Ltd., Niigata, Japan), gait speed was calculated from the Timed Up and Go test, and lean mass was estimated using a Tanita-305 body fat analyzer. We used logistic regression to examine associations between risk factors for prevalent sarcopenia at baseline and incident sarcopenia at follow-up. European Working Group on Sarcopenia in Older People sarcopenia was present in 21% of participants at baseline [149/719 participants, mean age 85.5 (0.4) years]. Many participants had either slow gait speed or weak grip strength (74.3%), and hence measurement of muscle mass was frequently indicated by the EWGSOP definition. Incidence data were available for 302 participants, and the incident rate was 3.7 cases per 100 person years at risk. Low Standardized Mini-Mental State Examination, lower occupational social class, and shorter duration of education were associated with sarcopenia at baseline, while low muscle mass was associated with incident sarcopenia. Low body mass index (BMI) was a risk factor for both in a graded fashion, with each unit decrease associated with increased odds of prevalent [odds ratio (OR) 1.29, 95% confidence interval (CI): 1.21, 1.37] and incident (OR 1.20, 95% CI: 1.08, 1

    Full Text Available OBJECTIVE Determine the coverage rate of syphilis testing during prenatal care and the prevalence of syphilis in pregnant women in Brazil. METHODS This is a national hospital-based cohort study conducted in Brazil with 23,894 postpartum women between 2011 and 2012. Data were obtained using interviews with postpartum women, hospital records, and prenatal care cards. All postpartum women with a reactive serological test result recorded in the prenatal care card or syphilis diagnosis during hospitalization for childbirth were considered cases of syphilis in pregnancy. The Chi-square test was used for determining the disease prevalence and testing coverage rate by region of residence, self-reported skin color, maternal age, and type of prenatal and child delivery care units. RESULTS Prenatal care covered 98.7% postpartum women. Syphilis testing coverage rate was 89.1% (one test and 41.2% (two tests, and syphilis prevalence in pregnancy was 1.02% (95%CI 0.84;1.25. A lower prenatal coverage rate was observed among women in the North region, indigenous women, those with less education, and those who received prenatal care in public health care units. A lower testing coverage rate was observed among residents in the North, Northeast, and Midwest regions, among younger and non-white skin-color women, among those with lower education, and those who received prenatal care in public health care units. An increased prevalence of syphilis was observed among women with < 8 years of education (1.74%, who self-reported as black (1.8% or mixed (1.2%, those who did not receive prenatal care (2.5%, and those attending public (1.37% or mixed (0.93% health care units. CONCLUSIONS The estimated prevalence of syphilis in pregnancy was similar to that reported in the last sentinel surveillance study conducted in 2006. There was an improvement in prenatal care and testing coverage rate, and the goals suggested by the World Health Organization were achieved in two regions

    This report evaluates the state of the art and effectiveness of physical coal cleaning as a potential strategy for controlling SO/sub x/ emissions in coal fired power generation. Coal properties which are significantly altered by physical coal cleaning were determined. The effects of the changes in properties as they relate to pulverized coal firing, fluidized bed combustion and low Btu gasification for combined cycle powered generation were studied. Available coal washability data were integrated by computer with U.S. coal reserve data. Approximately 18% of the demonstrated coal reserve were matched with washability data. Integrated data appear in the Appendix. Current coal preparation practices were reviewed. Future trends were determined. Five process flow sheets representing increasing levels of cleaning sophistication were prepared. The clean product from each flow sheet will meet U.S. EPA New Source Performance Standards. Capital and operating costs for each case were estimated. Environmental control technology and environmental impact associated with current coal preparation and cleaning operations were assessed. Physical coal cleaning is widely practiced today. Where applicable it represents the least expensive method of coal sulfur reduction. Developmental physical and chemical coal cleaning processes were studied. The chemical methods have the advantage of being able to remove both pyritic sulfur and organic sulfur present in the coal matrix. Further R and D efforts will be required before commercialization of these processes.

    This thesis consists of two parts. Part 1: Experimental and numerical study of jetfire stop, and Part 2: Experimental and numerical study of a new kind of shell and tube heat exchanger with helical flow on shell side. Part 1 describes the development of the model for simulation of the temperature development through Viking jetfirestop. A simulation program is developed that calculates the temperature development through Viking jetfirestop. In the development of the model, measurements of reaction energy, pyrolysis and heat conductivity at low temperatures are made. The conductivity at higher temperatures and when pyrolysis reactions are going on is estimated experimentally and by numerical calculations. Full-scale jet fire test and small-scale xenon lamp experiments are made to test the simulation model. Part 2 contains the development of a model that simulate the fluid flow and heat transfer in a helical flow shell and tube heat exchanger. It consists of the development of a porosity model and a model for pressure drop and heat transfer as well as experiments in non-standard tube layouts. Results from the simulation program are compared with experiments on a helical flow shell and tube heat exchanger. This is a separate appendix volume, including computer codes and simulated results. 316 figs., 11 tabs.

    The aim of this study was to compare the prevalences of obesity, diabetes and other cardiovascular risk factors in the region of Andalusia with those in the rest of Spain. The Di@bet.es study is a national, cross-sectional, population-based survey of cardiometabolic risk factors and their association with lifestyle. The sample consisted of 5103 participants ≥ 18 years. The variables analyzed were clinical, demographic and lifestyle survey, physical examination, and oral glucose tolerance test. The prevalence of cardiovascular risk factors in Andalusia (n=1517) was compared with that for the rest of Spain (n=3586). In data adjusted to the Spanish population, the prevalence of diabetes (World Health Organization, 1999), hypertension (blood pressure ≥ 140/90 mmHg), high-sensitivity CRP levels (≥ 3 mg/L) and obesity (body mass index ≥ 30 kg/m(2)) were 16.3%, 43.9%, 32.0%, and 37.0% in Andalusia compared with 12.5%, 39.9%, 28.3%, and 26.6% in the rest of Spain (Pdiabetes, hypertension and high-sensitivity CRP were not significant in models adjusted for age, sex, and adiposity measurements. Differences in obesity were not significant in models adjusted for age, sex, educational level, marital status, work status, and physical activity (P=.086) CONCLUSIONS: This study contributes information from a national study perspective and shows a higher prevalence of cardiovascular risk factors in southern Spain, in close relation to obesity, a sedentary lifestyle, and markers of socioeconomic disadvantage.

    Sleep disturbances apparently have a negative effect on pain or the appearance of pain itself. This suggests the need to determine whether there could be a relationship between obstructive sleep apnea-hypopnea syndrome (OSAHS) and this phenomenon. The objective of this study was to determine the pain prevalence in a population who underwent polysomnography. A cross-sectional study of patients who underwent polisomnography, pain prevalence was measured with Mcgill pain questionnaire. Data was obtained from 259 patients, and it was found that 69% suffered pain, and there was a prevalence of 81% OSAHS. Those with OSAHS had a 70% pain prevalence, with 64% for those without OSAHS. A high pain prevalence was found this population, possibly related to the characteristic of the population, how the information was gathered, and not controlling for other illnesses related with pain.

    Full Text Available Objectives: The prevalence of impacted teeth fluctuates across various ethnicities and geographical regions. The aim of the present study was to evaluate the prevalence and patterns of impacted teeth among patients living in the central part of Iran. Methods: This retrospective study was conducted on 3632 patients within the age group of 17-30 years. The frequency and pattern of the impaction were determined using orthopantomogram (OPG. Results: According to the results of the study, 56.3% of the patients were female (n=2046. Out of the 3632 OPGs, 1602 cases (44.1% were detected with at least one impacted tooth. No significant difference was observed between the males (n=682; 42.6% and females (n=920; 57.4% in this regard (P=0.237. Furthermore, the third molars were the most common impacted teeth found in 1156 radiographs (31.8% with no significant difference between the males (n=358; 30% and females (n=798; 70% (P=0.386. Mesioangular and distoangular impactions were detected to be the most frequent angulation of the impacted third molars in the mandible (49% and maxilla (41%, respectively. Additionally, 357 (9.8% and 78 (2.1% cases showed at least one impacted maxillary canine and one impacted mandibular second premolar, respectively. Moreover, impacted ectopic teeth were observed in 11 (0.3% individuals. Conclusion: Based on the findings of the present study, the third molar was the most common impacted tooth observed in the people living in the central region of Iran, followed by canine and second premolar impaction. The prevalence of the third molar impaction in the females was nearly twice as much as that in the males.

    Arteriovenous fistulas (AVFs) are the preferred form of hemodialysis vascular access, but maturation failures occur frequently, often resulting in prolonged catheter use. We sought to characterize AVF maturation in a national sample of prevalent hemodialysis patients in the United States. Nonconcurrent observational cohort study. Prevalent hemodialysis patients having had at least 1 new AVF placed during 2013, as identified using Medicare claims data in the US Renal Data System. Demographics, geographic location, dialysis vintage, comorbid conditions. Successful maturation following placement defined by subsequent use identified using monthly CROWNWeb data. AVF maturation rates were compared across strata of predictors. Patients were followed up until the earliest evidence of death, AVF maturation, or the end of 2014. In the study period, 45,087 new AVFs were placed in 39,820 prevalent hemodialysis patients. No evidence of use was identified for 36.2% of AVFs. Only 54.7% of AVFs were used within 4 months of placement, with maturation rates varying considerably across end-stage renal disease (ESRD) networks. Older age was associated with lower AVF maturation rates. Female sex, black race, some comorbid conditions (cardiovascular disease, peripheral artery disease, diabetes, needing assistance, or institutionalized status), dialysis vintage longer than 1 year, and catheter or arteriovenous graft use at ESRD incidence were also associated with lower rates of successful AVF maturation. In contrast, hypertension and prior AVF placement at ESRD incidence were associated with higher rates of successful AVF maturation. This study relies on administrative data, with monthly recording of access use. We identified numerous associations between AVF maturation and patient-level factors in a recent national sample of US hemodialysis patients. After accounting for these patient factors, we observed substantial differences in AVF maturation across some ESRD networks, indicating a

    Autism spectrum disorders (ASDs), once considered to be rare, are now reaching prevalence estimates of 1% and higher. Studies conducted in North America indicate large racial/ethnic disparities in the diagnosis of ASDs. Others show, that immigrant children have similar prevalence rates of ASDs as native children, although they are diagnosed later compared with native children. In relation to a EU funded network action, Enhancing the Scientific Study of Early Autism, it was considered important to review the literature on this subject. A comprehensive literature search was undertaken for original articles reporting on prevalence and risk for ASD in Europe among immigrants and ethnic minorities and data across studies were compared. Seventeen studies conducted in Europe concerning immigrants and ethnic minorities were found. Fifteen studies suggest a higher prevalence rate of ASDs among children of immigrants in comparison to native children (RR = 1.02-1.74; OR = 0.6-10.5). One study revealed higher prevalence of autism (OR = 2.2; 95% CI 1.6-3.1) and lower prevalence of Asperger syndrome in immigrants (OR = 0.6; 95% CI 0.3-0.97). One study showed a lower prevalence of Asperger syndrome in immigrants (aOR = 0.1, 95% CI 0.01-0.5). The majority of those analyses involved immigrants from outside Europe, e.g. from Africa and South America. After analysing the results of studies conducted in Europe, it is unclear if higher prevalence estimates of ASDs among immigrants in this region reflect true differences, especially considering many potential confounding factors, e.g. genetic, biological, environmental and cultural. Considering the number of people migrating within Europe there is a substantial need to study further the prevalence of ASDs in immigrant groups. © The Author 2016.

    Recently, an important literature data has reported that medical students experience stress more than students in other disciplines. In contrast, there is a significant shortage of the stress impact on the academic performance. The primary purpose of our study was to determine the prevalence of stress among Casablanca Medical students and to investigate if there is an association between stress and academic skills. A total of 275 participants studying at Casablanca Medical School were included. The study was conducted using a self-administered, anonymous questionnaire, which included four subscales on academic skills perception (Academic competence, Test competence, Time management and Strategic study habits) and a Test Anxiety scale to assess the degree of stress related to exams among medical students. The overall findings showed that 52.7% of respondents were stressed by examinations, and the highest stress prevalence was among the fifth-year medical students. Measures of comparative stress degrees between male and female students did not show any statistical significant differences (p=0.34). Correlation analysis revealed negative association between stress and academic competence (-0.394), test competence (-0.426), time management (-0.240), strategic study (-0.183) respectively (pstress among medical students, by establishing strategies for stress management.

    Full Text Available Background: Methicillin-resistant Staphylococcus aureus (MRSA is a cause of increased morbidity and mortality in debilitated and immunocompromised patients. Aims and Objectives: To study the prevalence of MRSA among dermatology inpatients and elucidate its predisposing factors and antibiotic sensitivity pattern. Materials and Methods: This prospective study involved all the inpatients in the dermatology ward with suspected bacterial infections, both primary and secondary. Gram′s stain, pus culture, and antibiotic sensitivity were the main tests done. Results: There were 61 patients in this study, with 36 males (59% and 25 females (41%. The age group maximally affected was 41-50 years (21.6%. Vesiculobullous disorders (22, 36.1% and eczemas (16, 26.2% were the commonest dermatoses with secondary infection. Extremities (72.1% and the trunk (26.2% were the commonest sites involved. Diabetes mellitus (DM was the commonest systemic illness (11.5%. Staphylococcus aureus was the commonest isolate, grown in 52 patients (85.2% of whom 16 (30.80% were MRSA positive. MRSA constituted 22.2% of the total bacterial isolates. All the MRSA isolates (100% were resistant to cloxacillin and oxacillin, while all the isolates (100% were sensitive to vancomycin and linezolid. Conclusions: The prevalence of MRSA in this study was high. It was most commonly seen in patients with vesiculobullous disorders. A high sensitivity of MRSA was found to amikacin. There was no relation between prolonged antibiotic therapy and MRSA in this study.

    Full Text Available Background: The prevalence of chronic diseases has increased with population ageing, and research has attempted to elucidate the correlation between chronic diseases and disability. However, most studies in older populations have focused on the effect of single disabling conditions, even though most older adults have more than one chronic disease (multimorbidity. Objective: The aims of this study were to evaluate the association of disability with disease, in terms of multimorbidity and specified pairs of diseases, in a population-based study of older adults. Materials and Methods: Using the Kungsholmen Project, we estimated the prevalence of disability by the number of chronic diseases, disease status by organ systems, and in specific pairs of chronic conditions, in a Swedish population (n=1,099; ≥77 years. Disability was defined as need of assistance in at least one activity of daily living (Katz index. Results: Functional disability was seen in 17.9% of participants. It increased as the number of chronic diseases increased. The prevalence of disability varied greatly amongst specific pairs of diseases: from 6.7% in persons affected by hypertension and atrial fibrillation to 82.4% in persons affected by dementia and hip fracture. In multivariate logistic regression models, the disease pairs that were significantly associated with the highest increased relative odds of disability contained dementia (dementia–hip fracture, dementia–CVD, and dementia–depression. Conclusions: Our findings suggest specific pairs of diseases are much more highly associated with disability than others, particularly diseases coupled with dementia. This knowledge may improve prevention of disablement and planning of resource distribution.

    To study the current prevalence of breastfeeding (BF) in Aragon (Spain) during the first 12 months of life, and analyse its demographic, perinatal and social influential factors. Obstetric, perinatal and feeding aspects were evaluated in a longitudinal and observational study, in a representative cohort of infant population from Aragon born between March 2009 to March 2010, controlled until 12 months of age (N=1.602). Exclusive or predominant BF was more frequent than the rest of feeding modalities during the first 4 months of life. Maintenance prevalence of any BF modality was 82.5% at 1(st) month of age, 71.8% at 3(rd), 54.3% at 6(th), and 27.8% at 12 months of age. Maternal variables that were significantly associated with BF maintenance both at 1 and 6 months of age were: delivery modality (higher probability in case of vaginal delivery), academic level (higher probability if university studies), origin (higher probability in mothers from Africa), adiposity (higher probability of normal weight or overweight mothers compared with obese ones), and not to smoke during gestation. BF prevalence in Aragon (Spain) during the first 12 months of age is high and has increased compared with previous data. BF continues in more than half of infants at six months and in a quarter of infants at 12 months of age. Maternal factors that significantly influence BF initiation and maintenance are, delivery modality, academic level, origin (immigration), adiposity and smoking habit.

    Full Text Available Abstract Background To determine the prevalence and characteristics of diabetic retinopathy (DR among Iranian patients with diabetes. Methods Design: population-based cross-sectional study. Participants: patients with diabetes aged 25 to 64 years in Tehran province, Iran. This survey was conducted from April to October 2007. The study sample was derived from the first national survey of risk factors for non-communicable disease. Diabetes mellitus was defined as a fasting plasma glucose of ≥ 7.0 mmol/l (126 mg/dl or more, use of diabetic medications, or a physician's diagnosis of diabetes. All patients known to have diabetes underwent an eye examination by bio-microscope and indirect ophthalmoscope to check for any signs of DR through dilated pupils by + 78 lens. Participants were also interviewed and examined to determine their demographic characteristics, medical conditions and the regularity of their eye visits. Results Among 7989 screened patients, 759 (9.5% had diabetes. Of them, 639 patients (84.2% underwent eye examination. Five patients (0.7% with media opacity were excluded. Of 634 examined patients with diabetes, 240 had some degree of diabetic retinopathy, and the overall standardized prevalence of any retinopathy was 37.0% (95% CI: 33.2-40.8, including 27.3% (95% CI: 23.7-30.8 (n = 175 with non-proliferative and 9.6% (95% CI: 7.3-11.9 (n = 65 with proliferative diabetic retinopathy. Clinically significant macular edema and vision-threatening retinopathy were detected in 5.8% (95% CI: 4.0-7.7 (n = 38 and 14.0% (95% CI: 11.3-16.7 (n = 95 of patients, respectively. Only 143 patients (22.6% with diabetes had a history of regular eye examination. Conclusion This study demonstrated a high prevalence and poor control of DR in Tehran province. This suggests the need for adequate prevention and treatment in patients with diabetes.

    Dysphagia is relatively common in patients with Parkinson disease (PD) and can have a negative impact on their quality of life; therefore, it is imperative that its prevalence in PD patients is studied. The aim of this study was to explore the prevalence and clinical correlation of dysphagia in Chinese PD patients. We recruited 116 Chinese PD patients. A videofluoroscopic study of swallowing (VFSS) was used to identify dysphagia. Assessments, including water drinking test, relative motor symptoms, non-motor symptoms (NMS) and quality of life, were performed to analyze the risks of dysphagia. The prevalence of dysphagia was 87.1%. The comparison of demographic and clinical features between patients with and without dysphagia included sex, education level, disease course, Mini-mental State Examination (MMSE), Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA), Question 6, 7 of the Unified Parkinson Disease Rating Scale (UPDRS Part II), Hoehn-Yahr stage (H&Y), water drinking test, 39-item Parkinson Disease Questionnaire (PDQ-39) and Non-Motor Symptoms Quest (NMSQ). We found significant correlations between dysphagia and age. Using age, disease course, and H&Y stage as the independent variable in our regression analysis for assessing the risk factors of dysphagia in PD patients, age and H&Y stage displayed a strong correlation as the risk factors. The risk of dysphagia in elderly PD patients is 1.078 times greater than that of younger PD patients. Also, the risk of dysphagia in PD patients of a greater H&Y staging is 3.260 times greater than that of lower staging PD patients. Our results suggest that dysphagia is common in Chinese PD patients. Older patients or those in higher H&Y stages are more likely to experience dysphagia. There is no correlation between dysphagia and PD duration.

    In October 2008 all three major banks in Iceland went bankrupt with serious consequences for Icelandic society. The national currency lost more than half of its value and there was a sharp increase in household debts and prices for domestic goods. Very little is known about the potential effects of economic recessions on gambling participation and problem gambling. This study reports on the results of three national prevalence studies conducted before and after the economic collapse in Iceland. The same methodology and measures were used in all three studies to ensure their comparability and the studies included in total N = 8.249 participants. There was an increase in past year gambling participation which extended across most gambling types. Only participation on EGMs declined significantly after the economic collapse. Past year prevalence of problematic gambling increased but further examination revealed that this increase is most probably explained by an increase in card and internet gambling among young men. Moreover, those who experienced financial difficulties due to the economic recession were 52% more likely to have bought a lottery ticket during the recession compared to those who were not affected financially. Overall, the results indicate that serious national economic recessions have differential effects on gambling behavior.

    Full Text Available BACKGROUND Migraine is a common, disabling primary headache disorder. It is a constellation of symptoms like headache, nausea, vomiting, photophobia and other similar neurological dysfunction in varying admixtures. Since, migraine is a neurovascular disease, the highly reactive amino acid, homocysteine has been postulated to play a role in migraine pathophysiology. MATERIALS AND METHODS A total of 30 migraine patients participated in the present study including 22 females and 8 males. The study was directed towards the aim of finding out the prevalence of hyperhomocysteinemia in migraine patients, which came out to be 13.3% and other aim is to show association if any between homocysteine level and severity of migraine in which we found no direct relationship between serum homocysteine level and severity of migraine. RESULTS The study was carried out from May to June, 2017, among consecutive patient attending the OPD of Medicine and Psychiatry Department. In all, 30 migraine patients and 30 controls were interviewed during this phase. The result of the present study has been analysed and tabulated. CONCLUSION Prevalence of hyperhomocysteinemia in migraine was found to be 13.3% and there was no significant relation found between serum homocysteine levels and severity of migraine. Mean serum homocysteine level was found to be higher in migraine patient as compared to control, but the association did not came out to be statistically significant.

    To assess the contribution of Human Norovirus to diarrhoeal diseases in Africa. We conducted a systematic review of the PubMed and EMBASE databases for published articles of Human Norovirus in Africa between 1990 and 2013. Data were extracted from selected studies and analysed. A total of 208 eligible studies were identified, of which 55 (from 19 countries) met the inclusion criteria. Many cases were of sporadic gastroenteritis (70.9%) in children (82%), 65.4% of which were seen in an outpatient setting. Over half (59.4%) of the affected children were under 5 years of age. The pooled prevalence rate of Human NoV was 11% (95% CI 8-14%), and the meta-analysis indicated significant heterogeneity between the studies. However, the conditional negative binomial regression could not clearly find the factors affecting the Human NoV prevalence rates reported. A close relationship was found between Human Norovirus strains from environmental and clinical samples. Unreported sporadic gastroenteritis cases of Human Norovirus are common in Africa. Most are community-associated infections. Possible environmental transmission routes have been documented. Combined environmental and clinical studies are required for targeted actions to control transmission of Human Norovirus in Africa. Systematic surveillance of Human Norovirus is needed to measure the burden of Norovirus-induced gastroenteritis in Africa and support any requirements for vaccine development. © 2015 John Wiley & Sons Ltd.

    Full Text Available Objective: To investigate the prevalence of Campylobacter jejuni (C. jejuni in the patients with gastroenteritis. Methods: This descriptive and analytical study included all adult patients with acute diarrhea admitted to the University Hospital of Zanjan Province who were enrolled in a one-year period from 2013 to 2014. Stool samples were checked for white blood cells (WBC and lactoferrin, then samples with WBC ≤ 5 positive for lactoferrin were selected for amplification of mapA gene of C. jejuni by RT-PCR assay. Results: In this study, 864 patients (410 men and 454 women with acute diarrhea were enrolled, of which about 718 patients had WBC less than 5 and 146 patients had WBC more than 5 in the stool exam. All inflammatory diarrhea samples were tested for lactoferrin and 111 cases of the samples tested were positive for lactferrin. A total of 40 samples out of 111 were positive for C. jejuni by RT. Conclusions: The finding of this study showed that the prevalence of inflammatory diarrhea and diarrhea caused by Campylobacter in this study was high. This need for education and awareness in this area, as well as appropriate treatment is too important.

    Prison is an extremely stressful environment and prisoners have an increasing risk of suffering from alexithymia. Therefore, this study aims to investigate the prevalence and associated factors of alexithymia among prisoners in China. A cross-sectional study was conducted in five main jails of the district of Zhejiang province in China, and a total of 1705 adult prisoners ultimately took part in the study. Toronto Alexithymia Scale, Childhood Trauma Questionnaire, Beck Depression Inventory, Beck Anxiety Inventory, Beck Hopelessness Scale and several short demographic questions were applied. Over 30% of prisoners were classified as alexithymics and as high as 96.2% of prisoners suffered from at least one traumatic experience in their childhood, meanwhile, 81.5%, 53.4% and 85.8% were found to be positive for depression, anxiety and hopelessness symptoms respectively. Education, childhood trauma, negative emotional symptoms including depression, anxiety and hopelessness of the respondents, were negatively or positively associated with alexithymia among prisoners. The results indicated that high prevalence of alexithymia among prisoners is linked with their level of education, experience of childhood trauma and symptoms of negative emotions. Accordingly, the findings in our study can be used for prevention and intervention of alexithymia among prisoners.

    In recent years there has been a progressive rise in the number of asylum seekers and refugees displaced from their country of origin, with significant social, economic, humanitarian and public health implications. In this population, up-to-date information on the rate and characteristics of mental health conditions, and on interventions that can be implemented once mental disorders have been identified, are needed. This umbrella review aims at systematically reviewing existing evidence on the prevalence of common mental disorders and on the efficacy of psychosocial and pharmacological interventions in adult and children asylum seekers and refugees resettled in low, middle and high income countries. We conducted an umbrella review of systematic reviews summarizing data on the prevalence of common mental disorders and on the efficacy of psychosocial and pharmacological interventions in asylum seekers and/or refugees. Methodological quality of the included studies was assessed with the AMSTAR checklist. Thirteen reviews reported data on the prevalence of common mental disorders while fourteen reviews reported data on the efficacy of psychological or pharmacological interventions. Although there was substantial variability in prevalence rates, we found that depression and anxiety were at least as frequent as post-traumatic stress disorder, accounting for up to 40% of asylum seekers and refugees. In terms of psychosocial interventions, cognitive behavioral interventions, in particular narrative exposure therapy, were the most studied interventions with positive outcomes against inactive but not active comparators. Current epidemiological data needs to be expanded with more rigorous studies focusing not only on post-traumatic stress disorder but also on depression, anxiety and other mental health conditions. In addition, new studies are urgently needed to assess the efficacy of psychosocial interventions when compared not only with no treatment but also each other

    Full Text Available Abstract Background The musculoskeletal disorders in working population represent one of the most worrying work-related health issues at the present time and although the very great majority of available data on the subject focus on musculoskeletal disorders defined by anatomical site, a growing number of studies indicate the low prevalence of disorders strictly confined to a specific anatomical site. The objective of this study was to describe the prevalence and characteristics of multisite musculoskeletal symptoms (multisite MS in a large French working population. Methods This study was performed on surveillance data of the cross-sectional survey (2002–2005 conducted by a network of occupational physicians in the working population of the Loire Valley region (from 20 to 59 years old. Data concerning MS were collected in the waiting room of the occupational physicians by means of the self-administrated standardized NORDIC questionnaire. Results The study population comprised 3,710 workers (2,162 men (58% and 1,548 women (42% with a mean age of 38.4 years (standard deviation: 10.4 years. The prevalence of MS during the past 12 months was 83.8% with 95% confidence interval of [82.8-85.3] for men and 83.9% [82.0-85.7] for women. The prevalence of subacute MS (lasting at least 30 days over the past 12 months was 32.8% [30.9-34.8] for men and 37.3% [34.9-39.7] for women. Two-thirds of workers reported MS in more than one anatomical site and about 20% reported MS lasting at least 30 days in more than one anatomical site. The anatomical sites most frequently associated with other MS were the upper back, hip, elbow and neck. The majority of these multisite MS were widespread, involving at least two of the three anatomical regions (upper limb, axial region and lower limb. Conclusions The frequency and extent of multisite MS reported by workers are considerable. Further research must be conducted in this field in order to provide a

    To determine the prevalence and causes of amblyopia in young adult Chinese, Indian, and Malay men in Singapore. A population-based cross-sectional study. Best-corrected visual acuities of all Singaporean men born in the years 1978 to 1983 were measured before enlistment into military service. Those with BCVA of 6/12 or worse were examined by an ophthalmologist for the presence of amblyopia and other causes. Of the 122,596 men examined, there were 428 with amblyopia, an overall prevalence of 0.35%. The prevalence was similar among Chinese (0.34%), Malays (0.37%), and Indians (0.41%, P = .52). Anisometropic amblyopia was the most common type of amblyopia and strabismic amblyopia was more common in Indians. There were little racial differences in the prevalence of meridional or form deprivation amblyopia. The overall prevalence of amblyopia was low and was similar among the three racial groups in young adult Singaporean males.

    Full Text Available Abstract Introduction: Sarcopenic obesity in older adults may lead to an inability to use muscles efficiently and has been associated with functional deficits and disabilities. Objective: To identify the prevalence of obesity and sarcopenic obesity (SO among community-dwelling older adults, and to characterize associated sociodemographics, health conditions and functional performance. Methods: Study data are from the FIBRA Network database of the Federal University of Minas Gerais. There were 1,373 older adult participants, subdivided into three groups: 1 non-obese; 2 non-sarcopenic obese; and 3 sarcopenic obese (SO. The latter is defined as a BMI ≥30 kg/m2 and weak palmar grip strength (PGS. Results: The overall prevalence of obesity and SO among older adults was 25.85% and 4.44%, respectively, with levels of frailty and pre-frailty among at 36.1% and 59%, respectively. Gait speed (GS was lower in the SO group as well, compared to the other groups. An average increase in GS of 0.1 m/sec reduced the likelihood of SO by 85.1%, in average. Sarcopenic obese older adults were 14.2 times more likely to be pre-fragile and 112.9 times more likely to be fragile than the other groups. Conclusion: The prevalence of obesity found in this study was higher than that in the general population, but similar to national statistics for the sample’s mean age and gender. SO was directly associated with frailty in advanced and instrumental activities of daily living as well as gait speed and significantly increased the likelihood of being pre-frail and frail. GS may be an extremely useful tool for monitoring the progress of SO in older adults.

    To determine the prevalence of refractive error and associated risk factors in the Meiktila District of central rural Myanmar. Population-based cross-sectional study. Randomized stratified cluster sampling of the inhabitants 40 years or older from villages in Meiktila was performed; 2481 eligible participants were identified, 2076 participated in the study, and adequate refractive data were obtained on 1863 individuals (75.1%). Demographic data including age, gender, and education level were obtained from all participants. The ophthalmic examination included autorefraction, nuclear opalescence (NO) grading at the slit lamp, and applanation tonometry. Refractive errors were classified by type of ametropia and their prevalence was determined. Univariate and multivariate analyses were performed and odds ratios were calculated for the predictors of refractive error within the statistical models. Mean refractive error measured -1.3 diopters (D) (standard deviation [SD], 2.9) and mean cylindrical error measured 1.1 D (SD, 1.5). Myopia of >-1.0 and >-6.0 D occurred in 42.7% (95% confidence interval [CI], 40.4%-44.9%) and 6.5% (95% CI, 5.4%-7.6%) of subjects, respectively. Myopic refractive error was associated significantly with a higher degree of NO (P+1.0 D occurred in 15% (95% CI, 5.4%-7.6%) of the population and was associated with higher education levels (Pprevalent in older subjects and in those with increased NO. The prevalence rates of myopia in the > or =40 age group are higher than those found in other Asian regions and are likely to contribute to visual impairment.

    Accumulating evidence amongst dental students indicates an alarming prevalence of stress, which can precipitate the development of burnout--a state of mental or physical exhaustion and disengagement. Understanding individual and educational correlates of burnout is necessary for its prevention. The aims of this study were to determine the prevalence of burnout amongst a large sample of Colombian dental undergraduates and investigate its psychosocial and educational correlates. Survey data collected from 5647 students participating in the Stress in Colombian Dental Education study were used for this analysis. Burnout was measured using the Maslach Burnout Inventory-Student Survey (MBI-SS). Covariates included participants' socio-demographic characteristics and perceived stress, as well as educational environment factors. Descriptive, bivariate and multivariate methods based on multilevel mixed-effects logistic regression modelling were used for data analysis. Seven per cent of the students surveyed met the criteria for burnout. The prevalence of burnout was higher amongst upper classes, older and married students, those who reported not having passed all required courses and not having dentistry as their first career choice, as well as students in public institutions and those with large class sizes. Moreover, students' perceived stress in the domains of workload and self-efficacy was significantly and positively associated with burnout. Both personal and educational environment characteristics were found to be associated with burnout. Irrespective of these factors, students' perceived stress with regard to workload and self-efficacy was a strong influence on burnout and its alleviation may be a promising avenue to prevent psychological morbidity. © 2014 John Wiley & Sons A/S.

    To assess the prevalence and severity of dysphonia in patients with cystic fibrosis sinusitis. We hypothesized that patients with CF sinusitis, compared with 2 control groups, would have higher self-reported prevalence of dysphonia and greater severity of dysphonia, according to patient-reported outcome measures as well as auditory-perceptual evaluation by expert listeners. Cross-sectional comparative pilot study. Academic tertiary care clinic. Analysis included 37 study participants: 17 patients with CF sinusitis, 10 healthy individuals, and 10 patients with non-CF sinusitis. All participants completed the 10-item Voice Handicap Index (VHI-10) questionnaire and provided voice samples. On all samples, 6 blinded speech-language pathologists independently performed auditory-perceptual evaluation, using Consensus Auditory-Perceptual Evaluation of Voice. To assess severity of sinonasal symptoms, we used the 20-item Sinonasal Outcome Test (SNOT-20). Standard parametric and nonparametric statistical analysis was performed. The differences between the 3 groups in prevalence of abnormal VHI-10 scores were not statistically significant. SNOT-20 scores were similar in the 2 sinusitis patient groups. VHI-10 scores were highest in patients with CF sinusitis, intermediate in patients with non-CF sinusitis, and lowest in healthy individuals (P = .005). Auditory-perceptual evaluation demonstrated greater overall severity of dysphonia in patients with CF sinusitis compared with the 2 control groups (P = .0005). Cystic fibrosis sinusitis appeared to be associated with worse vocal function as measured by patient self-report as well as auditory-perceptual evaluation of voice compared with patients with non-CF sinusitis and healthy controls. Further investigation in this area is warranted. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

    BACKGROUND Sepsis is a common cause of morbidity and mortality among hospitalized patients. The prevalence of this condition has increased significantly in different parts of the world. Patients admitted to dermatology wards often have severe loss of skin barrier and use systemic corticosteroids, which favor the development of sepsis. OBJECTIVES To evaluate the prevalence of sepsis among patients admitted to a dermatology ward compared to that among patients admitted to an internal medicine ward. METHODS It is a cross-sectional, observational, comparative study that was conducted at Hospital Santa Casa de Belo Horizonte. Data were collected from all patients admitted to four hospital beds at the dermatology and internal medicine wards between July 2008 and July 2009. Medical records were analyzed for the occurrence of sepsis, dermatologic diagnoses, comorbidities, types of pathogens and most commonly used antibiotics. RESULTS We analyzed 185 medical records. The prevalence of sepsis was 7.6% among patients admitted to the dermatology ward and 2.2% (p = 0.10) among those admitted to the internal medicine ward. Patients with comorbidities, diabetes mellitus and cancer did not show a higher incidence of sepsis. The main agent found was Staphylococcus aureus, and the most commonly used antibiotics were ciprofloxacin and oxacillin. There was a significant association between sepsis and the use of systemic corticosteroids (p <0.001). CONCLUSION It becomes clear that epidemiological studies on sepsis should be performed more extensively and accurately in Brazil so that efforts to prevent and treat this serious disease can be made more effectively.

    The purpose of this study was to test the feasibility of undertaking a full population investigation into the prevalence, incidence, and persistence of oral Human Papilloma Virus (HPV) in Scotland via dental settings. Male and female patients aged 16-69 years were recruited by Research Nurses in 3 primary care and dental outreach teaching centres and 2 General Dental Practices (GDPs), and by Dental Care Teams in 2 further GDPs. Participants completed a questionnaire (via an online tablet computer or paper) with socioeconomic, lifestyle, and sexual history items; and were followed up at 6-months for further questionnaire through appointment or post/online. Saline oral gargle/rinse samples, collected at baseline and follow-up, were subject to molecular HPV genotyping centrally. 1213 dental patients were approached and 402 individuals consented (participation rate 33.1%). 390 completed the baseline questionnaire and 380 provided a baseline oral specimen. Follow-up rate was 61.6% at 6 months. While recruitment was no different in Research Nurse vs Dental Care Team models the Nurse model ensured more rapid recruitment. There were relatively few missing responses in the questionnaire and high levels of disclosure of risk behaviours (99% answered some of the sexual history questions). Data linkage of participant data to routine health records including HPV vaccination data was successful with 99.1% matching. Oral rinse/gargle sample collection and subsequent HPV testing was feasible. Preliminary analyses found over 95% of samples to be valid for molecular HPV detection prevalence of oral HPV infection of 5.5% (95%CI 3.7, 8.3). It is feasible to recruit and follow-up dental patients largely representative / reflective of the wider population, suggesting it would be possible to undertake a study to investigate the prevalence, incidence, and determinants of oral HPV infection in dental settings.

    Full Text Available Demographic, socioeconomic, and urbanization level variations in Parkinson’s disease (PD are rarely investigated, especially in Asia. This study describes an eight-year trend in PD incidence and prevalence in Taiwan as well as assessing the effects of sociodemographics and urbanization on the incidence and prevalence of PD. The data analyzed were acquired from the Taiwan National Health Insurance Research Database (NHIRD entries between 2002 and 2009. The calendar year, sex, and age-specific rates were standardized, and the effects of the sociodemographics and urbanization on PD were assessed using Poisson regression analysis. PD incidence and prevalence showed a significantly increasing trend, with a greater magnitude noted for prevalence than for incidence (87.3% versus 9.2%. The PD incidence and prevalence increased with age and were slightly higher in men than in women. The people who were not under the labor force (i.e., dependents or with lower monthly incomes were at significantly increased adjusted incidence rate ratio (1.50–1.56 and adjusted prevalence rate ratio (1.66–1.71 of PD. Moreover, significantly higher PD incidence and prevalence were noted in areas with lesser urbanization. This information emphasizes the need for preventive and clinical care strategies targeting the segment of Taiwanese population that exhibited a greater incidence and prevalence of PD.

    Full Text Available Abstract Background Although studies have shown an association between anxiety and depression and obesity, psychological health among obese women during and after pregnancy has not been carefully studied. The aim of this study was to investigate psychological well-being using symptoms of depression and/or anxiety among obese pregnant women attending a weight gain restriction program and to then compare this group with a control group receiving traditional antenatal care. Methods 151 obese pregnant women in an intervention group and 188 obese pregnant women in a control group answered the Beck Anxiety Inventory (BAI and the Edinburgh Postnatal Depression Scale (EPDS. Group differences between the two groups were estimated by using the χ2 - test on categorical variables. The Student's t-test on continuous, normally distributed variables measuring changes in mean score on BAI and EPDS over time was used. To make a more comprehensive assessment of group differences, between as well as within the two groups, logistic regressions were performed with the BAI and EPDS as dependent variables, measured at gestational weeks 15 and 35 and 11 weeks postnatal. The grouping variable has been adjusted for socio-demographic variables and complications. Results The prevalence of symptoms of anxiety during pregnancy varied between 24% and 25% in the intervention group and 22% and 23% in the control group. The prevalence of symptoms of anxiety postnatally was 9% in the intervention group and 11% in the control group. Five percent of the women in the intervention group and 4% of the women in the control group showed symptoms of anxiety during the course of pregnancy and at the postpartum assessment. The prevalence of symptoms of depression during pregnancy varied between 19% and 22% in the intervention group but was constant at 18% in the control group. Postnatal prevalence was 11% in both groups. Six percent of the women in the intervention group and 4% in the

    Full Text Available Healthcare institutions have commonly reported exposure of employees, particularly nurses, to high levels of occupational violence. Despite such evidence in the Middle East Region, there is a dearth of national studies that have systematically investigated this phenomenon. This study investigates the prevalence, characteristics, consequences and factors associated with nurses' exposure to occupational violence in Lebanon.A cross-sectional design was utilized to survey a nationally representative sample of 915 nurses registered with the Order of Nurses in Lebanon. Stratified random sampling by governorate was utilized. Individually-mailed questionnaires collected information on exposure to violence, degree of burnout and demographic/professional background. The main outcome variables were exposure to verbal abuse (never, 1-3, 4-9 and 10+ times and physical violence (never, ever over the past 12-months. Descriptive statistics were used to estimate prevalence of violence. Multivariable, binomial and multinomial regression models were carried out to investigate the correlates of exposure to verbal abuse and physical violence, respectively.Response rate was 64.8%. Over the last year, prevalence of nurses' exposure to verbal abuse was 62%, (CI: 58-65% and physical violence was 10%, (CI: 8-13%. Among respondents, 31.7% of nurses indicated likelihood to quit their jobs and 22.3% were undetermined. Furthermore, 54.1% reported high levels of emotional exhaustion and 28.8% reported high levels of depersonalization. Compared to nurses with no exposure to verbal abuse, nurses reporting high exposure had high levels of emotional exhaustion (OR:6.4; CI:1.76-23.32, depersonalization (OR:6.8; CI: 3-15 and intention to quit job (OR:3.9; CI: 1.8-8.3. They further reported absence of anti-violence policies at their institutions (OR: 3; CI: 1.5-6.3. Nurses that were ever exposed to physical violence were more likely to be males (OR: 2.2; CI: 1.1-4.3, working day and

    Chronic erythematous candidiasis also known as denture-related stomatitis refers to inflammatory changes of the denture-bearing mucosa. The aim of this study was to evaluate the prevalence of chronic erythematous candidiasis in a Lebanese population using clinical and microbiological examinations. Ninety-eight patients wearing full acrylic maxillary denture (50 women and 48 men) were included in this study. A clinical oral assessment and a microbiological exam using swab samples collected from the palate of these patients were performed and the data obtained were analyzed statistically. Sixty-nine point thirty-eight per cent (69.38%) of the patients examined, (68 out of 98; 25 men and 43 women), presented chronic erythematous candidiasis. The statistical analysis showed that patient's gender was a significant predictor of the disease while no statistically significant relationship with the patient's age was found. Within the limits of this study, the prevalence of chronic erythematous candidiasis is estimated to be high in Lebanon. Women were more affected than men.

    Clinical evidence reveals the importance of mother-newborn bonding experience for health promoting and maintenance of human life. If the newborn lacks care and affection, she/he may develop an attachment disorder. A predictive scale regarding the risk of mothernewborn relationships is available, which makes possible an early intervention to prevent the development of relational disorders. The aim of this study is to apply the Kimelman measurement scale to determine the relational risk in mother-newborn pairs, as well as the prevalence and the associated biopsychosocial variables. A cross-sectional study with a probabilistic sample of 333 mother-infant pairs in postpartum maternity at Temuco hospital. The Kimelman mother-newborn attachment assessment guide was used. Biopsychosocial variables were obtained from the mothers studied. The association of biopsychosocial variables with relational risk was analyzed using OR and confidence intervals of 95%. The prevalence of high relational risk was 43.8%. The associated biopsychosocial variables included, women with no steady partner, single parent, teenage mothers, unwanted and unplanned pregnancy. Almost half of the mothers were in the high risk group. Early identification of relational risk and its related variables could help in the intervention in this vulnerable group. Copyright © 2015.

    Teeth are an interesting material for the study of ancient populations. The aim of our study was to determine the prevalence and distribution of caries in a medieval sample of paired maxillas in a rural population in Southwest France and to compare men and women. Our sample included 58 adults, 29 men and 29 women, with dentate maxillas in good state of conservation, for a total of 1,395 teeth out of a possible 1,846 (75%). The number of caries and their localization were noted. The frequency of antemortem missing teeth was 8.67%. The prevalence of caries was 17.46% and the most frequent caries were occlusal and proximal. Second and third molars were the most frequently affected maxillary and mandibular teeth. Caries on maxillary teeth were statistically more frequent than on mandibular teeth (p0.05). Our study showed that the frequency and the distribution of dental caries in this medieval population from southwest France were comparable to those of other European populations from the same period. The low level of caries was probably due to attrition and noncariogenic food. Differences between men and women were not significant, even though our results suggest that men were much more concerned by caries than women, especially for posterior teeth. A different diet may be the reason for this difference.

    Although cholera remains to be an important public health problem, studies on reliable population-based estimates of laboratory confirmed cholera in endemic areas are limited worldwide. The aim of this hospital-based study was to evaluate the prevalence of Vibrio cholerae serogroup in Assam, India, during 2003-2013. Stool samples/rectal swabs were collected from acute watery diarrhoea (AWD) cases during 2003-2013 and processed by standard microbiological procedures. Antibiotic sensitivity test was done following the Clinical and Laboratory Standards Institute guidelines. Year-wise epidemiological trend of cholera was analyzed. Cholera contributed to 3.93 per cent of AWD cases. In Assam, cholera was found to be more prevalent in the rural areas (6.7%) followed by the tea gardens (5.06%), urban slum (1.9%) and urban areas (1.4%). Highest proportion of cholera (13.7%) was observed in 0-10 yr age group. Of them, 11.5 per cent belonged to 0-5 yr age group. V. cholerae O1 El Tor serotype Ogawa was the predominant isolate. Multiple drug-resistant isolates of V. cholerae O1 Ogawa were reported in the study. Emergence of resistance amongst V. cholerae towards many antibiotics is a matter of concern. Hence, continuous surveillance for diarrhoeal disorders is necessary to control the future outbreaks of cholera in this region.

    Full Text Available Although historically tuberculosis (TB has been associated with poverty, few analytical studies from developing countries have tried to: 1. assess the relative impact of poverty on TB after the emergence of HIV; 2. explore the causal mechanism underlying this association; and 3. estimate how many cases of TB could be prevented by improving household socioeconomic position (SEP.We undertook a case-control study nested within a population-based TB and HIV prevalence survey conducted in 2005-2006 in two Zambian communities. Cases were defined as persons (15+ years of age culture positive for M. tuberculosis. Controls were randomly drawn from the TB-free participants enrolled in the prevalence survey. We developed a composite index of household SEP combining variables accounting for four different domains of household SEP. The analysis of the mediation pathway between household SEP and TB was driven by a pre-defined conceptual framework. Adjusted Population Attributable Fractions (aPAF were estimated. Prevalent TB was significantly associated with lower household SEP [aOR = 6.2, 95%CI: 2.0-19.2 and aOR = 3.4, 95%CI: 1.8-7.6 respectively for low and medium household SEP compared to high]. Other risk factors for prevalent TB included having a diet poor in proteins [aOR = 3.1, 95%CI: 1.1-8.7], being HIV positive [aOR = 3.1, 95%CI: 1.7-5.8], not BCG vaccinated [aOR = 7.7, 95%CI: 2.8-20.8], and having a history of migration [aOR = 5.2, 95%CI: 2.7-10.2]. These associations were not confounded by household SEP. The association between household SEP and TB appeared to be mediated by inadequate consumption of protein food. Approximately the same proportion of cases could be attributed to this variable and HIV infection (aPAF = 42% and 36%, respectively.While the fight against HIV remains central for TB control, interventions addressing low household SEP and, especially food availability, may contribute to strengthen our control

    Mitochondrial diseases are a heterogeneous group of diseases with different phenotypes and genotypes. Headache and, particularly migraine, seems to occur often in patients with MELAS and in patients with CPEO phenotypes. The International Classification of Headache Disorders (ICHD-3 beta) has classified headache as a secondary entity only in MELAS patients. Other headache phenotypes in mitochondrial diseases are not considered in ICHD-3beta. In this study, we analyzed headache phenomenology in a large group of patients with mitochondrial disorders. A cross-sectional questionnaire-based study on 85 patients with mitochondrial disease with different genotypes and phenotypes was conducted between 2010 and 2011. A structured headache questionnaire according to ICHD-2 was used followed by a telephone interview by a headache expert. Prevalence and characteristics of headache could be analyzed in 42 patients. Headache diagnosis was correlated with genotypes and phenotypes. In addition, the mtDNA haplotype H was analyzed. Headache was reported in 29/42 (70%; 95% CI, from 55.1 to 83.0%) of the patients. Tension-type headache (TTH) showed the highest prevalence in 16/42 (38%; 95% CI, from 23.4 to 52.8%) patients, followed by migraine and probable migraine in 12/42 (29%; 95% CI, from 14.9 to 42.2%) patients. Nine of the 42 (21%; 95% CI, from 9 to 33.8%) patients reported two different headache types. Patients with the mtDNA mutation m.3243A > G (n = 8) and MELAS (n = 7) showed the highest prevalence of headaches (88% and 85%, respectively). In patients with the CPEO phenotype (n = 32), headache occurred in 14/18 (78%; 95% CI, from 58.6 to 97%) of patients with single deletions, and in 7/13 (54%; 95% CI, from 26.7 to 80.9%) patients with multiple mtDNA deletions. There were no association between the mtDNA haplotype Hand the headache-diagnosis. The prevalence of headache was higher in patients with mitochondrial diseases than reported in the general population

    Analysis of the National Cancer Institute's Surveillance, Epidemiology, and End Results data has shown that the incidence of thyroid cancer is higher in patients with a preexisting malignancy and that the incidence of other malignancies is higher in patients with thyroid cancer. The purpose of this study was to evaluate the prevalence of a second malignancy in patients treated for thyroid, breast or renal cell cancer and determine what associations, if any, exist between these cancers. This study utilized the novel data system, Explorys, as its population base. Patient cohorts were constructed using ICD-9 codes, and prevalence rates were obtained for each cancer. Rates of second malignancy were obtained and compared to the baseline prevalence for a particular malignancy. Female thyroid cancer patients had a 0.67- and twofold increase in prevalence of a subsequent breast and renal cell cancer. Female breast and renal cell cancer patients had a twofold and 1.5-fold increase in the prevalence of thyroid cancer, respectively. Male patients with thyroid cancer had a 29- and 4.5-fold increase in prevalence of subsequent breast and renal cell cancer. Male patients with breast and renal cell cancer had an increased prevalence of subsequent thyroid cancer, 19- and threefold, respectively. Our study demonstrated a bidirectional association between thyroid, breast and renal cancer in both male and female patients. This may have important implications for patient follow-up and screening after treatment of a primary cancer.

    To investigate hypospadias' prevalence and trends, rate of surgical repairs and post-repair complications in an Australian population. Hypospadias cases were identified from all live-born infants in New South Wales, Australia, during the period 2001-2010, using routinely collected birth and hospital data. Prevalence, trends, surgical procedures or repairs, hospital admissions and complications following surgery were evaluated. Risk factors for reoperation and complications were assessed using multivariate logistic regression. There were 3186 boys with hypospadias in 2001-2010. Overall prevalence was 35.1 per 10,000 live births and remained constant during the study period. Proportions of anterior, middle, proximal and unspecified hypospadias were 41.3%, 26.2%, 5.8% and 26.6%, respectively. Surgical procedures were performed in 1945 boys (61%), with 1718 primary repairs. The overall post-surgery complication rate involving fistulas or strictures was 13%, but higher (33%) for proximal cases. Complications occurred after 1 year post-repair in 52.3% of cases and up to 5 years. Boys with proximal or middle hypospadias were at increased risk of reoperation or complications, but age at primary repair did not affect the outcome. One in 285 infants were affected with hypospadias, 60% required surgical repair or correction and one in eight experienced complications. The frequency of late complications would suggest that clinical review should be maintained for >1 year post-repair. Published by the BMJ Publishing Group Limited.

    The United States has the highest incarceration rate in the world which has created a public health crisis. Correctional facilities have become a front line for mental health care. Public health research in this setting could inform criminal justice reform. We determined prevalence rates for mental illnesses and related comorbidities among all inmates in a state prison system. Cross-sectional study using the Iowa Corrections Offender Network which contains health records of all inmates in Iowa. The point prevalence of both ICD-9 and DSM-IV codes for mental illnesses, timing of diagnosis and interval between incarceration and mental illness diagnosis were determined. The average inmate (N = 8574) age was 36.7 ± 12.4 years; 17% were ≥50 years. The majority of inmates were men (91%) and white (65%).Obesity was prevalent in 38% of inmates, and 51% had a history of smoking. Almost half of inmates were diagnosed with a mental illness (48%), of whom, 29% had a serious mental illness (41% of all females and 27% of all males), and 26% had a history of a substance use disorder. Females had higher odds of having both a mental illness and substance use disorder. Almost all mental illness diagnoses were first made during incarceration (99%). The mean interval to diagnosis of depression, anxiety, PTSD and personality disorders were 26, 24, 21 and 29 months respectively. Almost 90% of mental illnesses were recognized by the 6 th year of incarceration. The mean interval from incarceration to first diagnosis (recognition) of a substance abuse history was 11 months. There is a substantial burden of mental illness among inmates. Racial, age and gender disparities in mental health care are coupled with a general delay in diagnosis and treatment. A large part of understanding the mental health problem in this country starts at prisons.

    Full Text Available Introduction. With report of cases of griseofulvin resistant dermatophytes, the use of new Antifungal drugs such as itraconazole, fluconazole and terbinafine is recommended which are more expensive or somehow rare in Iran. Therefore, study of griseofulvin sensitivity pattern of dermatophytes in Isfahan could lead to a more effective and less expensive treatment for ermatophytoses. Methods. Fifty isolates of the most prevalent dermatophytes in Isfahan were isolated from patients and then the standard homogenized suspensions from them were prepared for future inoculation. The minimum inhibitory concemtration (MIC of Griseofulvin was determined by modified macrodiution method for each isolate and then results were compared and analysed with standard values of MICs of dermatophytes and the resistant species indentified. Results. All tested isolates (related to four species had MIC mode of 0.25, 90% had 8 and 50% ranged . between <0.25-1 µ.mg/ml. From all isolates, 10% of them including three T.verrucosum, one M. canis and one T. mentagrophytes had MIC out of standardized range, therfore, they considered as griseofulvin resistant isolates. Discussion. Although MIC valuses of drug in vivo and in vitro are somewhat different but in vitro values could be used as additional parameters in treatment of dermatophytoses, in particular its recalcitrant types or in areas which the resistant species may have high prevalence. In general, the proper application of griseofulvin and knowledge of prevalent species of dermatophytes of region and their drug sensitivity pattern could reduce the use of expensive and rare antifungal drugs for treatment of dermatophytoses in Iran.
