To investigate the etiology and complications of liver cirrhosis (LC) in Southern China. In this retrospective, cross-sectional study, we identified cases of liver cirrhosis admitted between January 2001 to December 2010 and reviewed the medical records. Patient demographics, etiologies and complications were collected, and etiological changes were illustrated by consecutive years and within two time periods (2001-2005 and 2006-2010). All results were expressed as the mean ± SD or as a percentage. The χ(2) test or Student's t-test was used to analyze the differences in age, gender, and etiological distribution, and one-way analysis of variance was applied to estimate the trends in etiological changes. We analyzed the relationship between the etiologies and complications using unconditioned logistic regression, and the risk of upper gastrointestinal bleeding (UGIB) and hepatocellular carcinoma (HCC) in the major etiological groups was evaluated as ORs. A P value less than 0.05 was considered significant. Statistical computation was performed using SPSS 17.0 software. In this study, we identified 6719 (83.16%) male patients and 1361 (16.84%) female patients. The average age of all of the patients was 50.5 years at the time of diagnosis. The distribution of etiological agents was as follows: viral hepatitis, 80.62% [hepatitis B virus (HBV) 77.22%, hepatitis C virus (HCV) 2.80%, (HBV + HCV) 0.58%]; alcohol, 5.68%; mixed etiology, 4.95%; cryptogenic, 2.93%; and autoimmune hepatitis, 2.03%; whereas the other included etiologies accounted for less than 4% of the total. Infantile hepatitis syndrome LC patients were the youngest (2.5 years of age), followed by the metabolic LC group (27.2 years of age). Viral hepatitis, alcohol, and mixed etiology were more prevalent in the male group, whereas autoimmune diseases, cryptogenic cirrhosis, and metabolic diseases were more prevalent in the female group. When comparing the etiological distribution in 2001-2005 with that in 2006-2010, the proportion of viral hepatitis decreased from 84.7% to 78.3% (P < 0.001), and the proportion of HBV-induced LC also decreased from 81.9% to 74.6% (P < 0.001). The incidence of mixed etiology, cryptogenic cirrhosis, and autoimmune diseases increased by 3.1% (P < 0.001), 0.5% (P = 0.158), and 1.3% (P < 0.001), respectively. Alcohol-induced LC remained relatively steady over the 10-year period. The ORs of the development of UGIB between HBV and other major etiologies were as follows: HCV, 1.07; alcohol, 1.89; autoimmune, 0.90; mixed etiology, 0.83; and cryptogenic, 1.76. The ORs of the occurrence of HCC between HBV and other major etiologies were as follows: HCV, 0.54; alcohol, 0.16; autoimmune, 0.05; mixed etiology, 0.58; and cryptogenic, 0.60. The major etiology of liver cirrhosis in Southern China is viral hepatitis. However, the proportions of viral hepatitis and HBV are gradually decreasing. Alcoholic LC patients exhibit a greater risk of experiencing UGIB, and HBV LC patients may have a greater risk of HCC.

Objective The purpose of this study was to review and compare the differences between mandibular fractures in young and adult patients. Material and Methods Patients treated at the Oral and Maxillofacial Department of Dicle University during a five-year period between 2000 and 2005 were retrospectively evaluated with respect to age groups, gender, etiology, localization and type of fractures, treatment methods and complications. Result 532 patients were included in the study, 370 (70%) males and 162 (30%) females, with a total of 744 mandibular fractures. The mean age of young patients was 10, with a male-female ratio of 2:1. The mean age of adult patients was 28, with a male-female ratio of 3:1. The most common causes of injury were falls (65%) in young patients and traffic accidents (38%) in adults. The most common fracture sites were the symphysis (35%) and condyle (36%) in young patients, and the symphysis in adults (36%). Mandibular fractures were generally treated by arch bar and maxillomandibular fixation in both young (67%) and adult (39%) patients, and 43% of the adult patients were treated by open reduction and internal fixation. Conclusion There was a similar gender, monthly and type of treatment distribution in both young and adult patients in the southeast region of Turkey. However, there were differences regarding age, etiology and fracture site. These findings between young and adult patients are broadly similar to those from other studies. Analysis of small differences may be an important factor in assessing educational and socioeconomic environments. PMID:20379677

Objective: To systematically search the literature and to summarize current evidence pertaining to the epidemiology of SCI in the MENA region incidence, gender, age, type of the injury and etiology of the injury. Methods: Embase, PubMed, Scopus, Web of Science and EBSCOhost were systematically searched from their dates of inception till July 2017 for English and non-English language articles. Also, regional databases were searched. Data were extracted from eligible articles and pooled under the random effect model using R. References of the included articles were also screened for potentially relevant studies. Results: We identified 29 articles from seven countries in the MENA region (Turkey, Iran, Saudi Arabia, Egypt, Jordan, Kuwait and Qatar). The mean age of the cases at time of injury was 31.32 (95% CI: 28.74-33.91). The random pooled annual incidence of TSCI per million was 23.24 (95% CI: 5.64-49.21). Pooled proportion of male gender was 77% (95% CI 73-80%) of the cases. Complete paraplegia was the most common type of injury. Thoracic level injury predominated. Also, the most commonly affected age group was 20-29 then 30-39. Motor vehicle accidents were found to be the leading cause of injury, then falls, gunshot, violence and sports. Further meta-regression analysis showed no association between age and etiology of the injury. Conclusion: This review shows lack of evidence about SCI in most countries of the MENA region. More epidemiological studies are needed. PMID:29719837

This study aims to present the data of mandibular fracture among children in the age group of 0-12 years treated in a district trauma center in India. Sixty-two children younger than 12 years treated for mandibular fractures over two-and-a-half-year period were studied by age, gender, anatomic site, etiology, socioeconomic status, residing area, interval from trauma to reporting, and treatment performed. The cases were divided into three age groups, and the records of the patients were analyzed. The male to female ratio was 1.58:1. Common fall and fall from bike together was a cause for injury in 50% (31 patients), of total patients. Condylar fractures occurred in 25 patients (40.3%). Multiple fractures were seen in 13% of the patients. In 47 (75.8%) patients, associated injuries other than the mandibular fractures were also present. Most patients with mandibular fractures were treated by closed reduction (36 patients, 58%). Conservative treatment and open reduction were done in 18 (29%) and 8 (13%) patients, respectively. In addition to factors such as age, gender, etiology, anatomic site, and treatment of mandibular fracture, this study also reported statistics regarding other factors such as residing area, socioeconomic status, and interval from trauma to reporting in Indian patients. It is hoped that the data presented here will be valuable to the government agencies and healthcare professionals for planning treatment, recommending preventive measures and encouraging research in this area. © 2015 John Wiley & Sons A/S.

Influence of age and gender before and after liver transplantation.

Women constitute a particular group among patients with chronic liver disease and in the post-liver transplantation (LT) setting: they are set apart not only by traditional differences with respect to men (ie, body mass index, different etiologies of liver disease, and accessibility to transplantation) but also in increasingly evident ways related to hormonal changes that characterize first the fertile age and subsequently the postmenopausal period (eg, disease course variability and responses to therapy). The aim of this review is, therefore, to evaluate the role of the interplay of factors such as age, gender, and hormones in influencing the natural history of chronic liver disease before and after LT and their importance in determining outcomes after LT. As the population requiring LT ages and the mean age at transplantation increases, older females are being considered for transplantation. Older patients are at greater risk for nonalcoholic steatohepatitis, osteoporosis, and a worse response to antiviral therapy. Female gender per se is associated with a greater risk for osteoporosis because of metabolic changes after menopause, the bodily structure of females, and, in the population of patients with chronic liver disease, the greater prevalence of cholestatic and autoimmune liver diseases. With menopause, the fall of protective estrogen levels can lead to increased fibrosis progression, and this represents a negative turning point for women with chronic liver disease and especially for patients with hepatitis C. Therefore, the notion of gender as a binary female/male factor is now giving way to the awareness of more complex disease processes within the female gender that follow hormonal, social, and age patterns and need to be addressed directly and specifically.

[Dramatic increase of gender dysphoria in youth].

Dramatic increase of gender dysphoria in youth In the past decade there has been a dramatic increase in the number of young people with gender dysphoria seeking help for gender-confirming medical interventions. From a situation of no more than a few patients annually, there were almost 200 referrals of gender dysphoria to the Astrid Lindgren Children's Hospital in 2016. This child and adolescent psychiatric unit has the whole country as a catchment area for patients <16 years. Gender-confirming medical interventions are regulated by a special law that sets a minimum age for legal and surgical gender reassignment to 18 years. The law, which is under revision, does not prevent medical investigations, hormonal therapy, and some surgical procedures before the age of 18. Gender dysphoria is defined as a persistent desire to live and be accepted as the opposite sex, usually accompanied by a perceived inconsistency with the sex assigned at birth and a desire to change the body in accordance with the perceived sex. The cause is unknown despite attempts of etiological mapping including genetic analyses, hormonal studies and modern brain imaging techniques. Repeated studies have shown that only a minority (about 20 %) of prepubertal children with gender dysphoria will have a persistent desire for later gender-confirming medical interventions, while the majority of those whose gender dysphoria is reinforced during puberty will later meet the diagnostic criteria for gender dysphoria (DSM-5) and transsexualism (ICD-10) (so called persisters). Persisters can be offered treatment with puberty stopping hormones to avoid the development of undesirable secondary sexual characteristics. Gender-confirming medical interventions are the only recommended treatment for gender dysphoria, and early treatment facilitates the ability to successfully pass in the desired sex, which is associated with a significantly better prognosis.

Few studies have investigated potential gender differences in the genetic and environmental influences on the prospective associations between parent-child conflict and later depression, a notable gap given substantial gender differences in rates of depression and suggestive evidence of differences in the etiology of depression among females and males. To fill this gap, we evaluated whether the prospective relationship between parent-child conflict and major depressive disorder symptoms varied as a function of parent-child gender composition. A combined twin and adoption sample was used (53% female; 85% European ancestry), containing 1,627 adolescent sibling pairs (789 monozygotic twin pairs, 594 dizygotic/full-biological pairs, 244 genetically unrelated pairs) with assessments at two time points in adolescence (approximate ages 15 and 18). Prospective associations between parent-child conflict and subsequent adolescent depression were explained predominately through common genetic influences for mother-daughter and mother-son pairs but less so for father-daughter and father-son pairs. Results support the notion that processes of gene-environment correlation involved in the prospective associations between parent-child conflict, and later adolescent depression appear to be less relevant to father-child relationships in comparison to mother-child relationships. Notably, results did not show that parent-child conflict was more relevant to the etiology of major depressive disorder (MDD) for girls than boys; gender differences in depression do not appear to be due to differences in the associations between parent-child conflict and child depression.

Attention-deficit/hyperactivity disorder (ADHD) is one of the most prevalent mental health disorders of childhood. Despite the availability of several evidence-based interventions, Latino children are more likely than non-minority children to have an unmet need for services related to ADHD. Given that parental beliefs about the etiology of ADHD likely influence service utilization, research needs to focus on cultural factors that may influence parental beliefs about the etiology of child behavior problems. Thus, the goal of the current study was to investigate the role of acculturation and cultural values of familism, respect, spirituality, and traditional gender roles in explaining parental etiological beliefs about ADHD in a sample of Latino parents. Findings suggest that behavioral acculturation was not significantly correlated with biopsychosocial or sociological/spiritual etiological beliefs; however, the cultural values of familism and traditional gender roles were positively correlated with sociological/spiritual beliefs. Further, exploratory analyses suggested that after controlling for SES, familism and traditional gender roles accounted for 30.5 % of the total variance in sociological/spiritual beliefs about ADHD. Finally, post hoc analyses revealed that cultural values were associated with several individual belief categories within the sociological/spiritual domain, including beliefs about friends, spirituality, and nature disharmony. The current study supports the inclusion of etiological beliefs and cultural factors in research examining help-seeking and access to mental health services among Latino families and suggests that the incorporation of alternative etiological beliefs about child behavior may be an important factor in culturally-appropriate mental health services.

Communication disabilities, including speech, language and voice disabilities, can significantly impact a person's quality of life, employment and health status. Despite this, little is known about the prevalence and etiology of communication disabilities in the general adult population. To assess the prevalence and etiology of communication disabilities in a nationally representative adult sample. We conducted a cross-sectional study and analyzed the responses of non-institutionalized adults to the Sample Adult Core questionnaire within the 2012 National Health Interview Survey. We used respondents' self-report of having a speech, language or voice disability within the past year and receiving a diagnosis for one of these communication disabilities, as well as the etiology of their communication disability. We additionally examined the responses by subgroups, including sex, age, race and ethnicity, and geographical area. In 2012 approximately 10% of the US adult population reported a communication disability, while only 2% of adults reported receiving a diagnosis. The rates of speech, language and voice disabilities and diagnoses varied across gender, race/ethnicity and geographic groups. The most common response for the etiology of a communication disability was "something else." Improved understanding of population prevalence and etiologies of communication disabilities will assist in appropriately directing rehabilitation and medical services; potentially reducing the burden of communication disabilities.

Lymphocele is a well-known postoperative complication after kidney transplantation. The aim of this study was to analyze time trend incidence, risk factors, and outcome of post-transplant lymphocele in a large pediatric cohort. This is a retrospective single institution review of 241 pediatric kidney transplants performed from 2000 to 2013. Etiology of end-stage renal disease, recipient age and gender, transplant year, BMI percentile for age, type of dialysis, living/non-living related donor, acute rejection, and multiple transplantations were analyzed in association with lymphocele formation. Fourteen of 241 (5.81%) children developed a postoperative lymphocele. There has been a reduction in the incidence of lymphocele after 2006 (3.22% vs. 8.55%, p < 0.05). Significant risk factors for lymphocele were older age (≥11 yr), transplant before 2006, male gender, BMI percentile for age ≥95%, and multiple transplantations (p < 0.05). The one-yr graft survival was significantly reduced in the group with lymphocele compared with control (81.2% vs. 92.51%, p < 0.04). This is the first pediatric report showing the following risk factors associated with post-transplant lymphocele: age ≥11 yr, male gender, BMI for age ≥95%, and multiple transplantations. A lymphocele can contribute to graft loss in the first-year post-transplant. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Severe aortic regurgitation (AR) is caused by a variety of mechanisms, which include the degenerative process, bicuspid aortic valve (BAV), aortic root dilation, endocarditis or a combination of these. Their frequency in a contemporary clinical series, and their impact on survival, are currently unknown. The authors' echocardiographic database between 1993 and 2007 was screened for patients with severe AR, and yielded 756 patients. Detailed chart reviews were performed to acquire clinical and demographic data. Mortality data were obtained from the social security death index and analyzed as a function of the condition's etiology. The probable etiologies for AR were: degenerative in 29% of patients, BAV in 10%, aortic root pathology in 11%, endocarditis in 10%, and mixed or unclear mechanism in 40%. Survival was a function of the etiology (p < 0.0001), with degenerative mechanism having the worst prognosis and BAV the best. This differential impact on mortality remained significant after adjusting for age, gender, coronary artery disease, diabetes mellitus, renal insufficiency, left ventricular ejection fraction and aortic valve replacement, using the Cox regression model (p < 0.0001). Etiology has a significant independent impact on mortality in patients with severe AR, with the worst survival being seen in degenerative AR.

To describe the reported incidence of out of hospital cardiac arrest (OHCA) and the characteristics and outcome after OHCA in relation to population density in Sweden. All patients participating in the Swedish Cardiac Arrest Register between 2008 and 2009 in (a) 20 of 21 regions (n=6457) and in (b) 165 of 292 municipalities (n=3522) in Sweden, took part in the survey. The regional population density varied between 3 and 310 inhabitants per km(2) in 2009. In 2008-2009, the number of reported cardiac arrests varied between 13 and 52 per 100,000 inhabitants and year. Survival to 1 month varied between 2% and 14% during the same period in different regions. With regard to population density, based on municipalities, bystander CPR (p=0.04) as well as cardiac etiology (p=0.002) were more frequent in less populated areas. Ambulance response time was longer in less populated areas (p<0.0001). There was no significant association between population density and survival to 1 month after OHCA or incidence (adjusted for age and gender) of OHCA. There was no significant association between population density and survival to 1 month after OHCA or incidence (adjusted for age and gender) of OHCA.

Tooth wear is becoming increasingly significant in the developed societies, because the etiological factors are frequently present in the daily life. The aim of this study was to assess the distribution of the tooth wear of the adult population in a private practice of dentistry. The group of study had 614 patients, structured on the following subgroups of age: 18- 30 years, 31-40, 41-50, 51-65 and more than 65 years old. Each patient had a clinical exam and a questionnaire for the diet and the lifestyle, spotlighting the etiology of tooth wear. attrition was the most frequent (55.7%), followed by abrasion (32.7%), erosion affected 7.5% of the patients and abfractions are the least frequent (4.1%). Erosions (9.7%) and attritions (59.9%) are more frequent at the feminine gender, and abrasions (40.4%) at the masculine gender. More than half of the abfractions (56%) were found at the youth patients (18-30 years old). Erosions were found in the 31-40 years subgroup at almost 40% of the patients; in the 41-50 years subgroup, abrasion and erosion were found in equal proportions. Abrasion prevails at the 51-65 years subgroup (30.8%). 72% of the consumers of acidic fruits had dental erosions. Tooth wear is under the influence of the diet and the age factor.

Objective. In the present study, we aimed to investigate epidemiological, clinical, and etiological characteristics of acute upper gastro-intestinal bleeding. Materials and Methods. This retrospective study was conducted between January 2003 and December 2008. It concerned all cases of acute upper gastroduodenal bleeding benefited from an urgent gastro-intestinal endoscopy in our department in Morocco. Characteristics of patients were evaluated in terms of age, gender, medical history, presenting symptoms, results of rectal and clinical examinations, and endoscopy findings. Results. 1389 cases were registered. As 66% of the patients were male, 34% were female. Mean age was 49. 12% of patients had a history of previous hemorrhage, and 26% had a history of NSAID and aspirin use. Endoscopy was performed in 96%. The gastroduodenal ulcer was the main etiology in 38%, followed by gastritis and duodenitis in 32.5%. Conclusion. AUGIB is still a frequent pathology, threatening patients' life. NSAID and aspirin are still the major risk factors. Their impact due to peptic ulcer remains stable in our country. PMID:21991509

Purpose While obesity disparities between racial and socioeconomic groups have been well characterized, those based on gender and geography have not been as thoroughly documented. This study describes obesity prevalence by state, gender, and race/ethnicity to (1) characterize obesity gender inequality, (2) determine if the geographic distribution of inequality is spatially clustered and (3) contrast the spatial clustering patterns of obesity gender inequality with overall obesity prevalence. Methods Data from the Centers for Disease Control and Prevention’s 2013 Behavioral Risk Factor Surveillance System (BRFSS) were used to calculate state-specific obesity prevalence and gender inequality measures. Global and Local Moran’s Indices were calculated to determine spatial autocorrelation. Results Age-adjusted, state-specific obesity prevalence difference and ratio measures show spatial autocorrelation (z-score=4.89, p-value <0.001). Local Moran’s Indices indicate the spatial distributions of obesity prevalence and obesity gender inequalities are not the same. High and low values of obesity prevalence and gender inequalities cluster in different areas of the U.S. Conclusion Clustering of gender inequality suggests that spatial processes operating at the state level, such as occupational or physical activity policies or social norms, are involved in the etiology of the inequality and necessitate further attention to the determinates of obesity gender inequality.

This population-based study was carried out in a well-defined geographical area, where all vascular surgical consultations and reconstructions are performed in one university hospital. All amputations performed in the region during 1990 - 1999 were identified from the hospital central registers. According to patient's identity codes, the Cause of Death Registry of Statistics Finland provided death data. Amputation data were cross-linked with the local vascular registry using identity codes. Women were found to be 8 years older than men (p < 0.0001). Major amputations comprised 73.4% in males and 77.7% in females. The age-standardized amputation incidence among males was 338 and among females 226 (per 10(6) inhabitants/year) (p < 0.001). The most prominent difference was seen in amputations due to trauma, where the age-adjusted major amputation incidence was over three-fold among males compared to females. The proportion of patients who had undergone vascular procedure before amputation was 23% in both genders. Median survival after amputation was 943 days in men and 716 in women (p = 0.01). When the higher age of women was considered, there was no significant difference between the genders. Survival was poorer among diabetics in both genders and the difference was significant in males. The amputation incidence was found to be higher in men compared to women in all etiologic subgroups except malignant tumour. Almost one in 4 patients had undergone vascular surgical reconstruction before amputation in both genders. There was no significant difference between the genders in survival after amputation. Subjects with diabetes had a poorer survival after major amputation than those without diabetes.

The absence of classical symptoms and signs of hyperthyroidism often results in delayed diagnosis and treatment. The objective of the study was to determine the prevalence of symptoms and signs of hyperthyroidism according to patients' age and gender as well as severity and type of hyperthyroidism. This was a cross-sectional study of 3049 consecutive patients with hyperthyroidism presenting to a single secondary/tertiary care clinic. Calculation of adjusted odds ratios for presence/absence of symptoms/signs of hyperthyroidism simultaneously analyzing the influence of patients' age/gender, disease etiology/severity, symptom duration, and smoking. The majority of patients older than 61 yr had two or more symptoms. The lowest proportion of subjects reporting five or more symptoms was found in those older than 61 yr. Increasing age was associated with reduced adjusted odds ratio for the presence of most classical symptoms except for weight loss and shortness of breath, independent of disease severity. Those with more severe hyperthyroidism and smokers had increased odds ratios for most symptoms. Older age, higher serum free T(4) concentrations at diagnosis, male gender, and toxic nodular hyperthyroidism were independently associated with risk of atrial fibrillation. Signs of ophthalmopathy were associated with increasing age, smoking, longer symptom duration, and female gender. Classical symptoms and signs of hyperthyroidism are significantly less prevalent in older patients and more prevalent in smokers and subjects with higher free T(4) concentrations. We propose a lower threshold for performing thyroid function tests in patients older than 60 yr, especially in those presenting with atrial fibrillation, weight loss, or shortness of breath.

AIM To investigate different etiologies and management of the rhabdomyolysis in children. METHODS Eight pediatric rhabdomyolysis cases who applied to the Dokuz Eylul University Faculty of Medicine Department of Pediatric Nephrology with different etiologies between January 2004 and January 2012 were evaluated in terms of age, gender, admission symptoms, physical examination findings, factors provoking rhabdomyolysis, number of rhabdomyolysis attacks, laboratory results, family history and the final diagnosis received after the treatment. RESULTS Average diagnosis ages of eight cases were 129 (24-192) ± 75.5 mo and five of them were girls. All of them had applied with the complaint of muscle pain, calf pain, and dark color urination. Infection (pneumonia) and excessive physical activity were the most important provocative factors and excessive licorice consumption was observed in one case. In 5 cases, acute kidney injury was determined and two cases needed hemodialysis. As a result of the further examinations; the cases had received diagnoses of rhabdomyolysis associated with mycoplasma pneumoniae, sepsis associated rhabdomyolysis, licorice-induced hypokalemic rhabdomyolysis, carnitine palmitoyltransferase II deficiency, very long-chain acyl-CoA dehydrogenase deficiency, congenital muscular dystrophy and idiopathic paroxysmal rhabdomyolysis (Meyer-Betz syndrome). CONCLUSION It is important to distinguish the sporadic and recurrent rhabdomyolysis cases from each other. Recurrent rhabdomyolysis cases should follow up more regardful and attentive. PMID:29184760

Adolescence is a key period in terms of the development of anxiety psychopathology. An emerging literature suggests that early pubertal maturation is associated with enhanced vulnerability for anxiety symptomatology, although few studies have examined this association with regard to social anxiety. Accordingly, the current study was designed to further elucidate the relation between pubertal timing and social anxiety, with a focus on clarifying the role of gender. Participants were 138 adolescents (ages 12-17 years) recruited from the general community. Level of social anxiety was examined as a function of gender and within-sample pubertal timing. As expected, early-maturing girls evidenced significantly higher social anxiety as compared to on-time girls and early-maturing boys, and no other differences were found as a function of gender or developmental timing. Findings and future directions are discussed in terms of forwarding developmentally-sensitive models of social anxiety etiology and prevention. PMID:21604866

The study of the etiological aspects of acute abdominal pain in children, in order to perceive the clinical-etiological correlations and the disorders distribution related to age, gender and the origin of the patients. The criteria for including patients were age (between 0 and 18 years) and the presence of acute abdominal pain before or during the consultation with the physician. The research on acute abdominal pain in children was performed on the level of the Surgery and Pediatrics II clinical departments of the "Sf. Ioan" Children's Emergency Clinical Hospital in Galati, between 01.01.2009 - 01.01.2011. The clinical study performed on the patients registered in the studied groups focused on the identification, the evaluation of the symptoms of acute abdominal pain in children, diagnosing and treating it. The criteria for excluding patients were an age older than 18 years or the absence of acute abdominal pain as a symptom before or during the examination. The statistical analysis used the descriptive and analytical methods. The data was centralized and statistically processed in M.S.EXCEL and S.P.S.S. databases. The patients with acute abdominal pain represent a percentage of 92.9% (2358 cases) of the total number of patients who suffer from abdominal pain (N=2537). The highest frequency of cases is represented by acute appendicitis (1056 cases - 44.8%). In the 5-18 years age group, acute appendicitis, mesenteric lymphadenitis, ovarian follicular cysts, acute pyelenophritis and salpingitis are predominant. In the 0-4 years age group gastroenteritis, acute pharyngitis, reactive hepatitis and lower digestive bleeding are predominant. In females, acute appendicitis, gastroenteritis, gastroduodenitis and cystitis are predominant, whereas in males, peritonitis, sepsis through E. coli, the contusion of the abdominal wall and acute pharyngitis are predominant.

Voice disorders affect adults and children and have different causes in different age groups. The aim of the study is to present the etiology and diagnosis dysphonia in a large population of patients with this voice disorder.for dysphonia of a large population of dysphonic patients. We evaluated 2019 patients with dysphonia who attended the Voice Disease ambulatories of a university hospital. Parameters assessed were age, gender, profession, associated symptoms, smoking, and videolaryngoscopy diagnoses. Of the 2019 patients with dysphonia who were included in this study, 786 were male (38.93%) and 1233 were female (61.07). The age groups were as follows: 1-6 years (n = 100); 7-12 years (n = 187); 13-18 years (n = 92); 19-39 years (n = 494); 41-60 years (n = 811); and >60 years (n = 335). Symptoms associated with dysphonia were vocal overuse (n = 677), gastroesophageal symptoms (n = 535), and nasosinusal symptoms (n = 497). The predominant professions of the patients were domestic workers, students, and teachers. Smoking was reported by 13.6% patients. With regard to the etiology of dysphonia, in children (1-18 years old), nodules (n = 225; 59.3%), cysts (n = 39; 10.3%), and acute laryngitis (n = 26; 6.8%) prevailed. In adults (19-60 years old), functional dysphonia (n = 268; 20.5%), acid laryngitis (n = 164; 12.5%), and vocal polyps (n = 156; 12%) predominated. In patients older than 60 years, presbyphonia (n = 89; 26.5%), functional dysphonia (n = 59; 17.6%), and Reinke's edema (n = 48; 14%) predominated. In this population of 2019 patients with dysphonia, adults and women were predominant. Dysphonia had different etiologies in the age groups studied. Nodules and cysts were predominant in children, functional dysphonia and reflux in adults, and presbyphonia and Reinke's edema in the elderly. Copyright © 2016 The Voice Foundation.

Although obesity disparities between racial and socioeconomic groups have been well characterized, those based on gender and geography have not been as thoroughly documented. This study describes obesity prevalence by state, gender, and race and/or ethnicity to (1) characterize obesity gender inequality, (2) determine if the geographic distribution of inequality is spatially clustered, and (3) contrast the spatial clustering patterns of obesity gender inequality with overall obesity prevalence. Data from the Centers for Disease Control and Prevention's 2013 Behavioral Risk Factor Surveillance System were used to calculate state-specific obesity prevalence and gender inequality measures. Global and local Moran's indices were calculated to determine spatial autocorrelation. Age-adjusted, state-specific obesity prevalence difference and ratio measures show spatial autocorrelation (z-score = 4.89, P-value < .001). Local Moran's indices indicate the spatial distributions of obesity prevalence and obesity gender inequalities are not the same. High and low values of obesity prevalence and gender inequalities cluster in different areas of the United States. Clustering of gender inequality suggests that spatial processes operating at the state level, such as occupational or physical activity policies or social norms, are involved in the etiology of the inequality and necessitate further attention to the determinates of obesity gender inequality.

This study was carried out to assess the clinical characteristics and associated systemic diseases seen in patients diagnosed with absent contractility as per the Chicago Classification version 3.0, allowing us to propose a diagnostic algorithm for their etiologic testing. The Chicago Classification version 3.0 has redefined major and minor esophageal motility disorders using high-resolution esophageal manometry. There is a dearth of publications based on research on absent contractility, which historically has been associated with myopathic processes such as systemic sclerosis (SSc). We conducted a retrospective, multicenter study. Data of patients diagnosed with absent contractility were pooled from Cleveland Clinic, Cleveland, OH (January 2006 to July 2016) and Metrohealth Medical Center, Cleveland, OH (July 2014 to July 2016) and included: age, gender, associated medical conditions, surgical history, medications, and specific antibody testing. A total of 207 patients, including 57 male individuals and 150 female individuals, with mean age of 56.1 and 60.0 years, respectively, were included. Disease distribution was as follows: SSc (diffuse or limited cutaneous) 132, overlap syndromes 7, systemic lupus erythematosus17, Sjögren syndrome 4, polymyositis 3, and dermatomyositis 3. Various other etiologies including gastroesophageal reflux disease, postradiation esophagitis, neuromuscular disorders, and surgical complications were seen in the remaining cohort. Most practitioners use the term "absent contractility" interchangeably with "scleroderma esophagus"; however, only 63% of patients with absent contractility had SSc. Overall, 20% had another systemic autoimmune rheumatologic disease and 16% had a nonrheumatologic etiology for absent contractility. Therefore, alternate diagnosis must be sought in these patients. We propose an algorithm for their etiologic evaluation.

Urinary tract infection (UTI) is the most common infection in renal transplant patients, but it is necessary to determine the risk factors for bacterial UTI in recipients of other solid organ transplants (SOTs), as well as changes in etiology, clinical presentation, and prognosis. In total, 4388 SOT recipients were monitored in 16 transplant centers belonging to the Spanish Network for Research on Infection in Transplantation (RESITRA). The frequency and characteristics of bacterial UTI in transplant patients were obtained prospectively from the cohort (September 2003 to February 2005). A total of 192 patients (4.4%) presented 249 episodes of bacterial UTI (0.23 episodes per 1000 transplantation days); 156 patients were kidney or kidney-pancreas transplant recipients, and 36 patients were liver, heart, and lung transplant recipients. The highest frequency was observed in renal transplants (7.3%). High frequency of cystitis versus pyelonephritis without related mortality was observed in both groups. The most frequent etiology was Escherichia coli (57.8%), with 25.7% producing extended-spectrum β-lactamase (ESBL). In all transplants but renal, most cases occurred in the first month after transplantation. Cases were uniformly distributed during the first 6 months after transplantation in renal recipients. Age (odds ratio [OR] per decade 1.1, 95% confidence interval [CI] 1.02-1.17), female gender (OR 1.74, 95% CI 1.42-2.13), and the need for immediate post-transplant dialysis (OR 1.63, 95% CI 1.29-2.05) were independent variables associated with bacterial UTI in renal and kidney-pancreas recipients. The independent risk factors identified in non-renal transplants were age (OR per decade 1.79, 95% CI 1.09-3.48), female gender (OR 1.7, 95% CI 1.43-2.49), and diabetes (OR 1.02, 95% CI 1.001-1.040). UTI was frequent in renal transplants, but also not unusual in non-renal transplants. Because E. coli continues to be the most frequent etiology, the emergence of ESBL-producing strains has been identified as a new problem. In both populations, most cases were cystitis without related mortality. Although the first month after transplantation was a risk period in all transplants, cases were uniformly distributed during the first 6 months in renal transplants. Age and female gender were identified as risk factors for UTI in both populations. Other particular risk factors were the need for immediate post-transplant dialysis in renal transplants and diabetes in non-renal transplants. © 2012 John Wiley & Sons A/S.

Objectives. Using Jackson Heart Study data, we examined whether perceived discrimination was associated with prevalent hypertension in African Americans. Methods. Everyday discrimination, lifetime discrimination, burden of discrimination, and stress from discrimination were examined among 4939 participants aged 35 to 84 years (women = 3123; men = 1816). We estimated prevalence ratios of hypertension by discrimination, and adjusted for age, gender, socioeconomic status, and risk factors. Results. The prevalence of hypertension was 64.0% in women and 59.7% in men. After adjustment for age, gender, and socioeconomic status, lifetime discrimination and burden of discrimination were associated with greater hypertension prevalence (prevalence ratios for highest vs lowest quartile were 1.08 [95% confidence interval (CI) = 1.02, 1.15] and 1.09 [95% CI = 1.02,1.16] for lifetime discrimination and burden of discrimination, respectively). Associations were slightly weakened after adjustment for body mass index and behavioral factors. No associations were observed for everyday discrimination. Conclusions. Further understanding the role of perceived discrimination in the etiology of hypertension may be beneficial in eliminating hypertension disparities. PMID:22401510

Gender identity disorder, or transsexualism as it is more commonly known, is a highly complex clinical entity. The general belief among behavioural scientists and physicians is that transsexualism is an identifiable and incapacitating disease which can be diagnosed and successfully treated by reassignment surgery. Although the exact etiology of gender identity disorder is unknown, several environmental, genetic and anatomical theories have been described. The reviewers draw attention to the possible genetic, hormonal, immunological and anatomical causes. An attempt is made to point out the future trends in research, highlighting their progressive features.

Theoretical models attempting to explain why approximately twice as many women as men suffer from depression often involve the role of stressful life events. However, detailed empirical evidence regarding gender differences in rates of life events that precede onset of depression is lacking, due in part to the common use of checklist assessments of stress that have been shown to possess poor validity. The present study reports on a combined sample of 375 individuals drawn from 4 studies in which all participants were diagnosed with major depressive disorder and assessed with the Life Events and Difficulties Schedule (Bifulco et al., 1989), a state-of-the-art contextual interview and life stress rating system. Women reported significantly more severe and nonsevere, independent and dependent, and other-focused and subject-focused life events prior to onset of depression than did men. Further, these relations were significantly moderated by age, such that gender differences in rates of most types of events were found primarily in young adulthood. These results are discussed in term of their implications for understanding the etiological role of stressful life events in depression. PsycINFO Database Record (c) 2010 APA, all rights reserved

Transgender Associations and Possible Etiology: A Literature Review.

Transgender or gender dysphoria has been defined in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), as distress resulting from the incongruence between one's experienced gender and one's assigned gender, along with a persistent and strong desire to be of another gender, and accompanied by clinically significant distress. Adolescents referred for evaluation often want hormonal therapy and several among them also express a desire for gender reassignment surgery. Furthermore, evidence shows that adolescents and adults with gender dysphoria without a sex development disorder, before gender reassignments, are at increased risk for suicide. For this review, a search of the English language scientific literature was conducted using the PubMed database. This summary discusses the associations and comorbidities of gender dysphoria and reiterates the evidence that its etiology is multifactorial. Transsexualism involves prenatal neuroanatomical changes, has a psychiatric association, and is found to be more prevalent in conjunction with schizophrenia and autism spectrum disorders. Childhood adversities and neglect are also linked to having a transgender identity. Moreover, the evidence favors a genetic predisposition. Likewise, there seems to be a growing concern with regards to the relationship between endocrine disruptors and transsexuals as well as other gender minority populations. More research needs to be done to understand the exact pathways.

Increased metabolism in the left auditory cortex has been reported in tinnitus patients. However, gender difference has not been addressed. To assess the differences in Positron emission tomography-computed tomography (PET-CT) results between the genders in tinnitus patients. Retrospective cohort. Included were patients referred to our clinic between January 2011 and August 2013 who complained of tinnitus and underwent fluorodeoxyglucose (FDG)-PET to assess brain metabolism. Univariate and multivariate nominal logistic regressions were used to evaluate the association between upper temporal gyrus (UTG; right and left) and gender. Included were 140 patients (87 males) with an average age of 52.5 yr (median = 53.1). Bilateral tinnitus was found in 85 patients (60.7%), left sided in 30 (21.4%), and right sided in 21(15%). Increased uptake in the UTG was found in 60% of the patients on either side. Males had a statistically significant increased uptake in the UTG in those with unilateral tinnitus and in the entire population. We present the largest study reported so far on tinnitus patients who have undergone FDG-PET-CT. We found a statistically significant difference between the genders in FDG uptake by the UTG. Further investigations should be undertaken to reveal the etiologies for these differences and to assess different therapeutic protocols according to gender. American Academy of Audiology

2012-01-01

Objective: The aim of the present study was to examine the periodontal condition of an adult population in three isolated regions in Greece and to determine the association of periodontal disease with several demographic, behavioral and environmental factors. Materials and Methods: The study population consisted of 640 individuals, aged 20 to 69 years from three isolated regions. The following indices were assessed: Pocket Depth (PD), Clinical Attachment Level (CAL), Dental Plaque, Calculus and Bleeding on Probing (BOP). Statistical analysis was accomplished by multiple linear regression model which was used to assess the association between the mean clinical attachment loss and clinical, demographic and behavioral parameters. Results: The samples of the study showed high levels of dental plaque, dental calculus and BOP. The final multivariate model showed that age (p=0.000), gender (p=0.016) and presence of calculus (p=0.000) were associated with the mean clinical attachment loss. Age (p=0.000), gender (p=0.000) and dental plaque (p=0.027) were associated with gingival recession, while age (p=0.018) and gender (p=0.000) were associated with probing depth. Bleeding on probing, dental plaque, toothbrush frequency, level of education, tobacco consumption and reasons for dental visits were not associated with the mean clinical attachment loss. Conclusion: Periodontal disease consists of a complicated destructive condition of the Periodontal tissue with a. multi-factorial etiology. Oral hygiene instructions and a regular dental follow-up could play a significant role in the prevention of periodontal disease. PMID:23119128

The objectives of this study were to compare the birth weight and gestational age distributions and prevalence rates of autism with those of other developmental disabilities and to estimate the birth weight-and gestational age-specific risks for autism. For the first objective, a retrospective cohort of children born in Atlanta, Georgia, in 1981-1993 who survived to 3 years of age was identified through vital records. Children in the cohort who had developmental disabilities (autism, mental retardation, cerebral palsy, hearing loss, or vision impairment) and were still residing in metropolitan Atlanta at 3 to 10 years of age were identified through the Metropolitan Atlanta Developmental Disabilities Surveillance Program. A nested case-control sample from the cohort was used for the second objective; all cohort children identified with autism were case participants, and control participants were cohort children who were not identified as having developmental disabilities or receiving special education services. The prevalence of autism in low birth weight or preterm children was markedly lower than those of other developmental disabilities. In multivariate analyses, birth weight of <2500 g and preterm birth at <33 weeks' gestation were associated with an approximately twofold increased risk for autism, although the magnitude of risk from these factors varied according to gender (higher in girls) and autism subgroup (higher for autism accompanied by other developmental disabilities). For example, a significant fourfold increased risk was observed in low birth weight girls for autism accompanied by mental retardation, whereas there was no significantly increased risk observed in low birth weight boys for autism alone. Gender and autism subgroup differences in birth weight and gestational age, resulting in lower gender ratios with declining birth weight or gestational age across all autism subgroups, might be markers for etiologic heterogeneity in autism.

To investigate the incidence, risk factors and the etiology of ventilator-associated pneumonia (VAP) in surgical emergency intensive care unit (ICU) patients. We conducted this prospective cohort study in the surgical emergency ICU of Istanbul Medical Faculty between December 1999 and May 2001. We included 100 mechanically ventilated patients in this study. We diagnosed VAP according to the current diagnostic criteria. We identified the etiology of VAP cases by both quantitative cultures of endotracheal aspiration and blood cultures. To analyze the predisposing factors for the development of VAP, we recorded the following variables: age, gender, acute physiology and chronic health evaluation (APACHE) II score, Glasgow coma scale (GCS), sequential organ failure assessment (SOFA) score, serum albumin level, duration of mechanical ventilation (MV) prior to the development of VAP, and underlying diseases. We determined the VAP incidence rate as 28%. We found the APACHE II score and the duration of MV to be statistically significant variables for the development of VAP. There were no significant differences regarding age, gender, GCS, SOFA score, albumin level, or underlying diseases for the development of VAP. The isolated bacteria among VAP cases were as follows: Staphylococcus aureus (n=12, 43%), Acinetobacter spp. (n=6, 21%), coagulase-negative Staphylococci (n=4, 15%), Pseudomonas aeruginosa (n=3, 10.7%) and Klebsiella pneumoniae (n=3, 10.7%). Ventilator-associated pneumonia is a common infection, and certain interventions might affect the incidence of VAP. The ICU clinicians should be aware of the risk factors for VAP, which could prove useful in identifying patients at high risk for VAP, and modifying patient care to minimize the risk of VAP.

Sarcoidosis is a multisystem granulomatous disease of unknown etiology. Current theory on the etiology of this disease involves participation of genetic factors and unknown antigens present in the patients' environment. The aim of the study was to evaluate the prevalence of different polymorphic forms of the ACE gene in healthy individuals and sarcoidosis patients, and to estimate the risk of sarcoidosis in carriers of different ACE genotypes living in rural and urban settings. The study group included 180 patients with pulmonary sarcoidosis. Assessment of the disease was based on clinical features, laboratory and imaging examinations, as well as bronchoscopy with bronchoalveolar lavage (BAL). ACE gene polymorphism was examined in DNA isolated from peripheral blood or BAL fluid (BALF) leukocytes. Incidence of sarcoidosis was not influenced by gender, age or place of residence of the patients. There were no differences in the frequency of particular genotypes in patients with sarcoidosis and in healthy individuals. The risk of disease did not depend on the ACE gene polymorphism. There were no differences in the frequencies of the different genotypes and alleles of the ACE gene in patients with sarcoidosis divided by gender, age and place of residence or by clinical manifestation of sarcoidosis. Our results do not support the previous concept which suggested a higher incidence of sarcoidosis in individuals living in rural areas and in carriers of selected ACE genotypes. It is possible that this is related to the changing environment of rural areas, increasing urbanization and pollution.

Background Chronic infections, including periodontal infections, may predispose to cardiovascular disease. We investigated the relationship between periodontal microbiota and subclinical atherosclerosis. Methods and Results Of 1056 persons (age 69±9 years) with no history of stroke or myocardial infarction enrolled in the Oral Infections and Vascular Disease Epidemiology Study (INVEST), we analyzed 657 dentate subjects. Among these subjects, 4561 subgingival plaque samples were collected (average of 7 samples/subject) and quantitatively assessed for 11 known periodontal bacteria by DNA-DNA checkerboard hybridization. Extensive in-person cardiovascular risk factor measurements, a carotid scan with high-resolution B-mode ultrasound, white blood cell count, and C-reactive protein values were obtained. In 3 separate analyses, mean carotid artery intima-media thickness (IMT) was regressed on tertiles of (1) burden of all bacteria assessed, (2) burden of bacteria causative of periodontal disease (etiologic bacterial burden), and (3) the relative predominance of causative/over other bacteria in the subgingival plaque. All analyses were adjusted for age, race/ethnicity, gender, education, body mass index, smoking, diabetes, systolic blood pressure, and LDL and HDL cholesterol. Overall periodontal bacterial burden was related to carotid IMT. This relationship was specific to causative bacterial burden and the dominance of etiologic bacteria in the observed microbiological niche. Adjusted mean IMT values across tertiles of etiologic bacterial dominance were 0.84, 0.85, and 0.88 (P=0.002). Similarly, white blood cell values increased across tertiles of etiologic bacterial burden from 5.57 to 6.09 and 6.03 cells × 109/L (P=0.01). C-reactive protein values were unrelated to periodontal microbial status (P=0.82). Conclusions Our data provide evidence of a direct relationship between periodontal microbiology and subclinical atherosclerosis. This relationship exists independent of C-reactive protein.

The purpose was to evaluate the incidence, etiology, site and patterns, management and treatment methods, and outcome of pediatric patients with mandibular fractures. Pediatric patients (1.5-16 years old) with mandibular fractures, treated at the Soroka University Medical Center were included in the study. Age, gender, etiology, site and type of fracture, associated injuries, mode of treatment, outcome, complications, and follow up were evaluated. The cases were divided into 3 age groups: Group A: 1.5-5 years, Group B: 6-11 years, and Group C: 12-16 years. Sixty one patients were included in the study. The male to female ratio was 2:1. Motor vehicle accident was the most common cause. Associated trauma was more common in young children. The condyle was involved in 54% of the fractures. Closed reduction and intermaxillary fixation was the most common treatment used. Complications were rare. Management of mandibular fracture in the pediatric age group is a challenge. The anatomical complexity of the developing mandible and teeth strongly suggest the use of surgical techniques that are different from those routinely used in adults. The conservative approach is recommended. Whenever possible closed reduction should be the treatment of choice. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

To report demographic data from a large cohort of patients with oromandibular dystonia (OMD). This is a retrospective review of patients with OMD referred to our institution between 1989 and 2015. Demographic (age of onset, gender, and familial history of dystonia) and clinical (type of OMD, associated dystonia, and etiology of dystonia) data were collected from a cohort of 240 individuals. The mean age of onset of OMD was 51.6 years old, with a female predominance (2:1). A family history of dystonia was found in 6 patients (2.5%). One hundred and forty-nine patients (62.1%) had the jaw-opening type of OMD, 48 patients (20.0%) had the jaw-closing type, and 43 patients (17.9%) had a mixed form of OMD. Lingual dystonia was also present in 64 (26.7%) of these patients. Eighty-two patients (34.2%) had a focal dystonia, 131 patients (54.6%) had a segmental dystonia, and 27 patients (11.3%) had a generalized dystonia. One hundred and seventy-one patients (71.3%) had idiopathic OMD. OMD is a chronic and disabling focal dystonia. Our study found a prevalence of female patients, an onset in middle age and a predominantly idiopathic etiology. Unlike other studies, jaw-opening was found to be the most frequent clinical type of OMD.

Objective Executive Function, a set of cognitive skills important to social and academic outcomes, is a specific area of cognitive weakness in children with congenital heart disease (CHD). We evaluated the prevalence and profile of executive dysfunction in a heterogeneous sample of school aged children with CHD, examined whether children with executive dysfunction are receiving school services and support, and identified risk factors for executive dysfunction at school age. Design 91 school aged patients completed questionnaires, including the Behavior Rating Inventory of Executive Function (BRIEF) and a medical history questionnaire. An age and gender matched control sample was drawn from a normativedatabase. Results CHD patients had a higher rate of parent reported executive dysfunction (OR=4.37, p<0.0001), especially for working memory (OR=8.22, p<0.0001) and flexibility (OR=8.05, p<0.0001). Those with executive dysfunction were not more likely to be receiving school services (p>0.05). Gender, premature birth (≤37 weeks), and CHD with aortic obstruction were predictive of executive dysfunction, especially for behavior regulation skills. Conclusions School aged children with CHD have an increased prevalence of executive dysfunction, especially problems with working memory and flexibility, and are underserved by the school system. The increased risk for executive dysfunction in those with CHD and prematurity or CHD with aortic obstruction suggests an etiology of delayed brain development in the fetal and neonatal periods, while male gender may increase susceptibility to brain injury. This study highlights the need for regular neurodevelopmental follow up in children with CHD, and a need to better understand mechanisms that contribute to adverse neurodevelopmental outcomes.

Suicide and suicidal behaviour

Summary Suicide is a complex public health problem of global dimension. Suicidal behaviour (SB) shows marked differences between genders, age groups, geographic regions and socio-political realities, and variably associates with different risk factors, underscoring likely etiological heterogeneity. Although there is no effective algorithm to predict suicide in clinical practice, improved recognition and understanding of clinical, psychological, sociological, and biological factors may facilitate the detection of high-risk individuals and assist in treatment selection. Psychotherapeutic, pharmacological, or neuromodulatory treatments of mental disorders can often prevent SB; additionally, regular follow-up of suicide attempters by mental health services is key to prevent future SB.

Objective Refractory status epilepticus (RSE) is a life-threatening disease in children wherein the patient’s convulsive seizures do not respond to adequate initial anticonvulsants. RSE is associated with high rate of mortality and morbidity. This study was aimed to survey the risk factors leading status epilepticus (SE) to RSE in children, and their early outcome. Materials & Methods Patients with SE hospitalized in Tabriz Children’s Hospital, Iran were studied during the years 2007 and 2008 with regard to their clinical profile, etiology, the treatment methods available to them and their outcome upon release from the hospital. Results Among 132 patients with SE, 53 patients (40.15%) suffered from RSE. Acute symptomatic etiology was a risk factor responsible for developing RSE in the patient (P=0.004). Encephalitis was the most common etiology of acute symptomatic SE. There was no significant relationship observed between RSE and the patients’ age, gender, date of initial drug intake and type of seizure. The mortality rate was 8.3% and a new neurological deficit occurred in 25.7% of cases. None of RSE with encephalitis returned to the baseline status. Mortality and morbidity rates were significantly higher in children with RSE than in those with SE (P=0.006). Conclusion Etiology of SE significantly influenced prognosis of it with significant incidence of RSE in acute symptomatic group. Because acute neurological insult such as encephalitis and meningitis are common causes of RSE in children, properly management of them is necessary to avoid permanent brain damage. PMID:26664438

It is unknown if health-related quality of life (HRQoL) differs between diseases associated with chronic pruritus (CP). To analyze HRQoL in relation to age, gender, skin lesions (primary vs. scratch-induced secondary) and itch intensity. Consecutive patients of our itch clinic were assessed with the Dermatology Life Quality Index (DLQI) and visual analogue scale (VAS). In 510 CP patients (282 females; median age, 61.4 years), DLQI scores and VAS values were highly correlated, irrespective of the type of skin lesion. Overall, women had a lower HRQoL compared to men (females: 10.7 ± 6.7, males: 8.9 ± 6.7), but female gender was only associated with worse quality of life in patients <65 years old. HRQoL impairment in CP is highly influenced by pruritus intensity but not to the visible skin lesion or underlying cause. With limitations to item bias, DLQI is a suitable instrument for estimating quality of life impairment by CP. © 2015 S. Karger AG, Basel.

After routine workup, 23-25% of ischemic strokes etiology remains unknown, i.e. cryptogenic. However, according to international results pathogenic patent foramen ovale (PFO) reveals in 25% of these cases. Aim of our retrospective study to prove the substantial etiological role of PFO-related stroke (PFO-RS) in cryptogenic strokes (CS), and to identify age related differences in stroke etiology. All new ischemic strokes of 2014-2015 were classified by ASCOD (Atherosclerosis, Small-vessel disease, Cardiac pathology, Other, Dissection) phenotyping. CS was defined when the etiology was unknown. With the help of special ultrasound techniques and RoPE (Risk of Paradoxical Embolism) score the portion of PFO-RS were determined in the examined CS population. Moreover, etiological distribution and differences between age groups (<40, 40-60, >60 years) were described. During the examined period, 8.12% of 985 new ischemic strokes were categorized as CS. 41.38% of examined CS were found to be PFO-related. PFO-RS were considerably more frequent in the younger age groups than in the older age groups. The probability of appearance of PFO-RS were significantly higher in younger age than in case of age independency. Our results verify the substantial etiological role of PFO-RS in CS, and confirm the essential role of contrast enhanced functional transcranial Doppler in the routine diagnostic workup. Age related differences in stroke etiology were found to be statistically significant (p=0.000, df=14), in which small-vessel disease, cardiac pathology, dissection, other pathologies, CS and PFO-RS were contributed significantly. Based on our results, till in young age rare etiologies are typical, while in older age classical etiologies are mainly characteristic.

Background: Facial fracture is gradually become a public health problem in our community due to the attendant morbidity and mortality. Hence, the aim of this study was to determine the pattern of facial fracture in Dental and Maxillofacial Surgery Department of Usmanu Danfodiyo University Teaching Hospital. This cross-sectional study was undertaken to provide information regarding gender, age, etiology, and diagnosis of patients with maxillofacial fractures. Materials and Methods: A 1-year review of patients diagnosed and treated for facial fractures in Usmanu Danfodiyo University Teaching Hospital between January 2011 and December 2011. The diagnosis was based on radiographic data and clinical examination. The main analysis outcome measures were etiology, age, gender, site, and treatment. Data were organized and presented by means of descriptive statistics and Pearson's Chi-square test. The level of significance adopted was 5%. Results: A total of 40 patients were treated in this period. Over 95% were male, 81% were caused by road traffic crash (RTC) and 86.4% were in the 21-30 years group. Most patients (52%) had mandibular fractures, and the most common site was the body. Most patients with midfacial fractures had fractures of the zygomaticomaxillary region (36%), while fractures of the parasymphyseal region were more common in the mandible 156 (31%). The most common treatment for jaw fractures was mandibulomaxillary fixation (MMF). Stable zygomatic complex fractures were reduced (elevated) intraorally, and unstable ones were supported by antral packs. Conclusions: This study highlights facial fractures secondary to RTC as a serious public health problem in our environment. Preventive strategies remain the cheapest way to reduce direct and indirect costs of the sequelae of RTC. It also bring to the fore the necessity to shift to open reduction and internal fixation (ORIF) of fractures. PMID:24741422

The aims of this study were to: examine the expression of open bite in prematurely born children and discuss the etiological factors that may lead to bite it. The subjects were 328 prematurely born (<37 gestational weeks) Caucasoid and African American children and 1,804 full-term control children, who participated in the cross-sectional study of the Collaborative Perinatal Project in the 1960s and 1970s. Dental documents, including casts and photographs, were taken once at the age of 6-12 years in the mixed dentition. The occlusion was recorded by examining and measuring the hard stone casts. Vertical open bite was recorded only for full erupted teeth. The statistical method used was chi-square analysis. Significant differences in the incidence of anterior open bite (from left to right canine) was found between the preterm and control groups and between gender and ethnic groups. The prevalence of anterior open bite was nearly 9% in the preterm group and almost 7% in the control group. African Americans (9%) had a significantly greater incidence of open bite than Caucasians (3%; P<.0001). Generally, girls had a greater incidence of open bite than boys (8% vs 6%; P<.11). When the study groups were divided by prematurity, gender, and ethnic group, the prevalence of open bite was increased--especially in preterm African American boys compared to controls (11% vs 8%). The results show differences in the development of anterior open bite between ethnic and gender groups. Premature birth may also influence dental occlusal development. Of importance are the patient's: general health condition; respiratory infections; inadequate nasal- and mouth-breathing; oral habits; and other medical problems. Preterm children may be relatively more predisposed to etiological factors for the development of anterior open bite.

The Puzzle of Male Chronophilias.

Seto, Michael C

2017-01-01

In this article, I return to the idea that pedophilia, a sexual interest in prepubescent children, can be considered a sexual orientation for age, in conjunction with the much more widely acknowledged and discussed sexual orientation for gender. Here, I broaden the scope to consider other chronophilias, referring to paraphilias for age/maturity categories other than young sexually mature adults. The puzzle of chronophilias includes questions about etiology and course, how chronophilias are related to each other, and what they can tell us about how human (male) sexuality is organized. In this article, I briefly review research on nepiophilia (infant/toddlers), pedophilia (prepubescent children), hebephilia (pubescent children), ephebophilia (postpubescent, sexually maturing adolescents), teleiophilia (young sexually mature adults, typically 20s and 30s), mesophilia (middle-aged adults, typically 40s and 50s), and gerontophilia (elderly adults, typically 60s and older) in the context of a multidimensional sexual orientations framework. Relevant research, limitations, and testable hypotheses for future work are identified.

 Benign idiopathic tonsillar hypertrophy (HBI) may affect a child's quality of life and sleep. Several studies have sought to relate the clinical features of HBI with the infectious and/or immunologic changes that occur.  To increase the knowledge of the etiology of HBI.  From 2012 to 2013 we conducted a retrospective observational study of 101 children with HBI who underwent tonsillectomies at Ambulatory ENT General Hospital of the East Zone of São Paulo City, a region with a poor socioeconomic population. Preoperative serologic results were available to confirm mononucleosis, cytomegalovirus, anti-streptolysin O (ASLO) and immunoglobulins. The mean patient age was 5.8 years (55% male, 45% female). Using the Mann-Whitney U test, we identified significant gender differences in the parameters of immunoglobulins (Ig) M (IgM), IgA, and IgE. Forty-seven percent of the patients had increased ASLO levels, and 37% had increased IgE levels.  An evaluation of a patient's serologic parameters and laboratory results may be relevant to the etiology and prevention of HBI. Based on the results obtained from the study sample, the identification of etiologic agents and causative factors remain a public health challenge that affects the quality of life of children.

Gender aspects in heart failure. Pathophysiology and medical therapy.

2004-09-01

Gender differences in the syndrome of heart failure (HF) occur in etiology and pathophysiology and lead to differences in the clinical presentation and course of the syndrome. In addition, gender specific treatment responses and gender associated differences in the behavior of treating physicians are found. Hypertension and diabetes play a major role as causes of HF in women and both interact in their pathophysiology with the renin angiotensin system (RAS). Modulation of the RAS by estrogens explains specific differences between pre- and post-menopausal women and men. Myocardial growth processes and myocardial calcium handling are differentially regulated in female and male myocytes. Myocardial remodeling with age and as a consequence of mechanical load differs in women and men. For yet unknown reasons, HF with preserved systolic function seems to be more frequent in women than in men and the clinical course of systolic HF is different in both genders. Medical therapy in heart failure has usually not been specified according to gender and gender specific analysis has been neglected in most large survival trials. Only a post-hoc analysis of gender differences led to the recognition of increased mortality with digitalis therapy in women. Single studies on angiotensin converting enzyme inhibitors (ACEI) or beta-receptor blockers did not reach significant end points in women whereas meta-analyses showed overall positive effects. Side effects of ACEI are more common and pharmacokinetics of beta-blockers are different in women. Angiotensin receptor blockers (ARB) are equally well tolerated in women and men. RAS inhibition may be particularly advantageous in postmenopausal women in whom the natural modulation of the RAS by estrogens is lost.

Suicidal behavior and its prevention constitute a major public health issue. Etiology of suicidal behavior is multifactorial. Whereas current research is mostly focused on clinical and biological risk factors, the sociodemographic risk factors for suicidal behavior, first highlighted by Durkheim, have received less attention. Besides the well-known impact of age and gender, sociodemographic variables such as marital and parental status, education, occupation, income, employment status, religion, migration or minority status, and sexual orientation are repeatedly reported to play an important role in suicidal behavior. This narrative review aimed to summarize recent research on sociodemographic risk factors for suicidal behavior and to elicit possible implications for suicide prevention.

Age, Predisposing Diseases, and Ultrasonographic Findings in Determining Clinical Outcome of Acute Acalculous Inflammatory Gallbladder Diseases in Children

2016-01-01

We evaluated clinical factors such as age, gender, predisposing diseases and ultrasonographic findings that determine clinical outcome of acute acalculous inflammatory gallbladder diseases in children. The patients were divided into the four age groups. From March 2004 through February 2014, clinical data from 131 children diagnosed as acute acalculous inflammatory gallbladder disease by ultrasonography were retrospectively reviewed. Systemic infectious diseases were the most common etiology of acute inflammatory gallbladder disease in children and were identified in 50 patients (38.2%). Kawasaki disease was the most common predisposing disease (28 patients, 21.4%). The incidence was highest in infancy and lowest in adolescence. The age groups were associated with different predisposing diseases; noninfectious systemic disease was the most common etiology in infancy and early childhood, whereas systemic infectious disease was the most common in middle childhood and adolescence (P = 0.001). Gallbladder wall thickening was more commonly found in malignancy (100%) and systemic infection (94.0%) (P = 0.002), whereas gallbladder distension was more frequent in noninfectious systemic diseases (60%) (P = 0.000). Ascites seen on ultrasonography was associated with a worse clinical course compared with no ascites (77.9% vs. 37.7%, P = 0.030), and the duration of hospitalization was longer in patients with ascites (11.6 ± 10.7 vs. 8.0 ± 6.6 days, P = 0.020). In conclusion, consideration of age and predisposing disease in addition to ultrasonographic gallbladder findings in children suspected of acute acalculous inflammatory gallbladder disease might result in better outcomes.

Objective: To evaluate the clinical characteristics and etiologies of central diabetes insipidus (CDI). Methods: The clinical data of 230 patients with CDI in the Department of Endocrinology of Chinese PLA General Hospital from 2008 June to 2014 December were collected and analyzed retrospectively. Results: The three most common causes of CDI were idiopathic CDI, lymphocytic hypophysitis and intracranial germ cell tumors. Among all the CDI, the idiopathic CDI accounted for 37.48%. There were significant differences in age onset and gender distribution among the different causes of CDI. The patients with intracranial germ cell tumors [age of onset(19.2±10.2) years] were younger than the other types of CDI. Germ cell tumors patients were more common in male, and lymphocytic hypophysitis patients were more common in female. The most frequent abnormality of anterior pituitary in patients with CDI was growth hormone deficiency, followed by hypogonadism, adrenal insufficiency and hypothyroidism. The dysfunction of thyroid axis and adrenal axis in patients with germ cell tumor was more common than those in patients with idiopathic and lymphocytic hypophysitis. Conclusions: The most common causes of central diabetes insipidus were idiopathic CDI, lymphocytic hypophysitis and intracranial germ cell tumors. There were differences in age of onset, gender distribution and abnormal production of anterior pituitary hormones among all causes of CDI patients.

Body weight and obesity show familial resemblance that could be the result of familial correlation of fat oxidation, low levels of which have been implicated in the etiology of weight gain and obesity. We studied the familial correlation of both 24-h respiratory quotient (RQ), an index of the ratio of fat to carbohydrate oxidation, and the possible influence of dietary macronutrient composition expressed by the food quotient (FQ), i.e. the theoretical RQ produced by the diet. We measured the habitual FQ of the 7 days diet by weighed food records, followed by measurement of 24-h RQ in respiration chambers in 71 healthy Caucasian siblings from 31 families. After adjustment for age, gender, and 24-h energy balance, 24-h RQ correlated in families as indicated by an intraclass correlation coefficient (r(i)) of 0.31 (P = 0.03). FQ, adjusted for age and gender, was also a familial trait for the two days immediately preceding diet (r(i) = 0.32, P < 0.01). The familial effect on 24-h RQ, adjusted for age, gender, and 24-h energy balance, remained after adjustment for the FQ of the two days preceding diet (r(i) = 0.27, P < 0.05) and was reduced but not abolished after further adjustment for fasting plasma insulin plus free fatty acids (r(i) = 0.24, P < 0.09). By a correlation analysis aimed at separating familial and individual nonfamilial factors influencing both 24-h RQ and FQ, we found a great but insignificant familial (etaF = 0.49, P < 0.18) and a somewhat lower, but significant individual nonfamilial correlation (etaNF = 0.35, P < 0.03). We conclude that substrate oxidation rates measured by RQ exhibit familial correlation after proper adjustment for confounders such as energy balance, gender, and age, and that this effect could not be fully explained by preceding diet composition, fasting plasma insulin, and free fatty acids. Further RQ and the habitual dietary composition shared familial and nonfamilial factors.

Fatigue is a common problem, which is found more frequently among women than men. To date, neither the etiology of fatigue nor the factors that explain the gender difference in its incidence are still fully understood. In a sample of men (n = 4,681) and women (n = 4,698) (age range, 15-64 years) in the Dutch National Survey of Morbidity and Interventions in General Practice, the gender differences in the underlying biological, psychological, and social factors of fatigue were analyzed. Both general and gender-specific factors were recognized. Men and women who experience complaints of fatigue appeared to be younger and more highly educated. They had more acute health complaints and more psychosocial problems and also showed a lower level of perceived health. Among women, only gender-specific biological complaints and psychosocial problems were related to fatigue. In addition, relevant sociodemographic variables included taking care of young children and being employed. Among men, fatigue was particularly related to having handicaps and severe chronic complaints. Taking care of young children did not make a difference in the male sample. Fatigue can only be adequately understood in a multicausal model with biomedical and psychosocial factors. Complaints of fatigue are too often ignored in general practice. By adopting a patient-centered style of communication, physicians can acquire a more complete picture of the patients' fatigue.

Objective The relationship between sex/gender differences and autism has attracted a variety of research ranging from clinical and neurobiological to etiological, stimulated by the male bias in autism prevalence. Findings are complex and do not always relate to each other in a straightforward manner. Distinct but interlinked questions on the relationship between sex/gender differences and autism remain underaddressed. To better understand the implications from existing research and to help design future studies, we propose a 4-level conceptual framework to clarify the embedded themes. Method We searched PubMed for publications before September 2014 using search terms “‘sex OR gender OR females’ AND autism.” A total of 1,906 articles were screened for relevance, along with publications identified via additional literature reviews, resulting in 329 articles that were reviewed. Results Level 1, “Nosological and diagnostic challenges,” concerns the question, “How should autism be defined and diagnosed in males and females?” Level 2, “Sex/gender-independent and sex/gender-dependent characteristics,” addresses the question, “What are the similarities and differences between males and females with autism?” Level 3, “General models of etiology: liability and threshold,” asks the question, “How is the liability for developing autism linked to sex/gender?” Level 4, “Specific etiological–developmental mechanisms,” focuses on the question, “What etiological–developmental mechanisms of autism are implicated by sex/gender and/or sexual/gender differentiation?” Conclusions Using this conceptual framework, findings can be more clearly summarized, and the implications of the links between findings from different levels can become clearer. Based on this 4-level framework, we suggest future research directions, methodology, and specific topics in sex/gender differences and autism. PMID:25524786

Choosing the antimicrobial agent for initial therapy of urinary tract infection (UTI) is usually empirical and should consider the prevalence of uropathogens in different age groups and gender. To establish prevalence rates of uropathogens in community-acquired UTI in relation to age and gender. Cross-sectional study conducted in the emergency department (ED) of a general hospital, from January to December, 2010, in patients younger than 15 years old who had clinical suspicion of UTI and collected quantitative urine culture. UTI was defined as urine culture with growth of a single agent > 100.000 colony forming units (cfu)/mL in a midstream collection or ≥ 50.000 cfu/mL in urethral catheterization. There were 63.464 visits to ED. 2577 urine cultures were obtained, of whom 291 were positive for UTI (prevalence = 11.3% of clinical suspicion and 0.46% of visits), 212 cases (72.8%) in females, median age = 2.6 years. The predominant uropathogen was E. coli (76.6%), followed by Proteus mirabilis (10.3%) and Staphylococcus saprophyticus (4.1%). Among infants < 3 months, prevalence rates of E. coli were significantly lower (50% vs 78.4%; OR = 0.276; p = 0.006). Higher prevalences of Staphylococcus saprophyticus occurred among patients > 10 years (24.4% vs 0.4%; OR = 79.265; p < 0.0001). Proteus mirabilis was significantly more prevalent in boys than girls (24.0% vs 5.2%; OR = 5.786; p < 0.001). E. coli was the most prevalent community-acquired uropathogen. Nevertheless, initial empiric antimicrobial treatment of UTI should consider the significant prevalence of other agents different from E. coli in infants < 3 months, the high prevalence of Staphylococcus saprophyticus in patients > 10 years and Proteus mirabilis in males.

To analyze mortality associated with hepatitis C virus (HCV) and hepatitis B virus (HBV) infection in Italy. Death certificates mentioning either HBV or HCV infection were retrieved from the Italian National Cause of Death Register for the years 2011-2013. Mortality rates and proportional mortality (percentage of deaths with mention of HCV/HBV among all registered deaths) were computed by gender and age class. The geographical variability in HCV-related mortality rates was investigated by directly age-standardized rates (European standard population). Proportional mortality for HCV and HBV among subjects aged 20-59 years was assessed in the native population and in different immigrant groups. HCV infection was mentioned in 1.6% ( n = 27730) and HBV infection in 0.2% ( n = 3838) of all deaths among subjects aged ≥ 20 years. Mortality rates associated with HCV infection increased exponentially with age in both genders, with a male to female ratio close to unity among the elderly; a further peak was observed in the 50-54 year age group especially among male subjects. HCV-related mortality rates were higher in Southern Italy among elderly people (45/100000 in subjects aged 60-79 and 125/100000 in subjects aged ≥ 80 years), and in North-Western Italy among middle-aged subjects (9/100000 in the 40-59 year age group). Proportional mortality was higher among Italian citizens and North African immigrants for HCV, and among Sub-Saharan African and Asian immigrants for HBV. Population ageing, immigration, and new therapeutic approaches are shaping the epidemiology of virus-related chronic liver disease. In spite of limits due to the incomplete reporting and misclassification of the etiology of liver disease, mortality data represent an additional source of information for surveillance.

Clinical features of pedophilia and implications for treatment.

The authors discuss the diagnostic criteria for pedophilia and review the literature on its clinical features, including data on prevalence, gender, age of onset, number of victims, frequency and type of acts, violence, impulsivity, and insight. Findings concerning the characteristics of victims (e.g., sex, age, relationship to the pedophile) and research on pedophilic subtypes-exclusive versus nonexclusive; incestuous versus nonincestuous; heterosexual, homosexual, or bisexual-are reviewed. Studies have shown that pedophiles may share many psychiatric features beyond deviant sexual desire, including high rates of comorbid axis I disorders (affective disorders, substance use disorders, impulse control disorders, other paraphilias) as well as severe axis II psychopathology (especially antisocial and Cluster C personality disorders). The authors present several possible etiological models for pedophilia and conclude that further research is needed concerning the etiological role of a childhood history of sexual abuse as well as the underlying neurobiology of deviant sexual arousal and decreased erotic differentiation. Finally, findings concerning pharmacological and cognitive-behavioral treatments for pedophilia are briefly reviewed. Recidivism, drop-out, and noncompliance are significant problems in the treatment of pedophilia. The authors review predictors of treatment outcome and conclude that pedophilia is extremely difficult to treat and that effective treatment needs to be intensive, long-term, and comprehensive, possibly with lifetime follow-up.

This study recommends using soft surgical principal and round window insertion to protect residual hearing with favorable anatomical exposure. Further studies are needed to evaluate the impact of the electrical stimulation on the organ of corti and hearing. The objective of this study is to analyze various factors that impact on preservation of residual hearing post-implantation. A retrospective study was performed to analyze loss of residual hearing in a cohort of 225 patients implanted in a large academic center. Sixty-four patients met the inclusion criteria. The impact of age at implantation, gender, etiology of hearing loss, cochleostomy vs round window insertion, partial vs full insertion, and effect of initial stimulation were analyzed using appropriate statistical analysis. The overall hearing preservation rate for all implanted patients was 64%. Loss of residual hearing was significantly more observed in cases of cochleostomy and/or non-soft surgical techniques. No correlation was observed with age at implantation, gender, side of implant, device manufacturer, and presence of pre-lingual deafness vs post-lingual, full or partial electrode insertion. In addition, there was a small but significant decrease in hearing between pre-stimulation and post-stimulation audiograms at 6000 Hz.

Gender identity disorder is a rare disorder of uncertain etiology. The emphasis on body shape in this disorder suggests that there may be an association with anorexia nervosa. We report two cases of anorexia nervosa and gender identity disorder in biologic males who presented to an eating disorders service. One was treated successfully as an outpatient and subsequently underwent gender reassignment surgery. The other patient required admission and prolonged psychotherapy. Differences between the two cases are discussed. Issues of gender identity should be considered in the assessment of male patients presenting with anorexia nervosa.

Tinea capitis is generally considered as the most frequent fungal infection in childhood, as it accounts for approximately 92% of all mycosis in children. The epidemiology of this disease varies widely ranging from antropophillic, zoophilic, and geophillic dermatophytes, as the main causative agent in different geographic areas, depending on several additional factors. Nowadays, the etiology is considered to vary with age, as well with gender, and general health condition. The former reported extraordinary Tinea capitis case reports have been replaced by original articles and researches dealing with progressively changing patterns in etiology and clinical manifestation of the disease. This fact is indicative that under the umbrella of the well-known disease there are facts still hidden for future revelations. Herein, we present two rare cases of Tinea capitis in children, which totally differ from the recently established pattern, in their clinical presentation, as well as in the etiological aspect, as we discuss this potential new etiological pattern of the disease, focusing on our retrospective and clinical observation. Collected data suggest that pathogenic molds should be considered as a potential source of infection in some geographic regions, which require total rationalization of the former therapeutic conception, regarding the molds' higher antimitotic resistance compared to dermatophytes. Molds-induced Tinea capitis should be also considered in clinically resistant and atypical cases, with further investigations of the antifungal susceptibility of the newest pathogens in the frame of the old disease. Further investigations are still needed to confirm or reject this proposal. Copyright © 2016 Elsevier Editora Ltda. All rights reserved.

Transsexualism: A Different Viewpoint to Brain Changes.

PubMed

Mohammadi, Mohammad Reza; Khaleghi, Ali

2018-05-31

Transsexualism refers to a condition or belief which results in gender dysphoria in individuals and makes them insist that their biological gender is different from their psychological and experienced gender. Although the etiology of gender dysphoria (or transsexualism) is still unknown, different neuroimaging studies show that structural and functional changes of the brain result from this sexual incongruence. The question here is whether these reported changes form part of the etiology of transsexualism or themselves result from transsexualism culture, behaviors and lifestyle. Responding to this question can be more precise by consideration of cultural neuroscience concepts, particularly the culture-behavior-brain (CBB) loop model and the interactions between behavior, culture and brain. In this article, we first review the studies on the brain of transgender people and then we will discuss the validity of this claim based on the CBB loop model. In summary, transgender individuals experience change in lifestyle, context of beliefs and concepts and, as a result, their culture and behaviors. Given the close relationship and interaction between culture, behavior and brain, the individual's brain adapts itself to the new condition (culture) and concepts and starts to alter its function and structure.

2017-06-01

The plantar calcaneal spur (PCS) is a bony outgrowth from the calcaneal tuberosity and has been studied using various methods including cadavers, radiography, histology and surgery. However, there are currently a number of discrepancies in the literature regarding the anatomical relations, histological descriptions and clinical associations of PCS. Historically, authors have described the intrinsic muscles of the foot and/or the plantar fascia as attaching to the PCS. In this article we review the relationship between the PCS and surrounding soft tissues as well as examining the histology of the PCS. We identify a number of key associations with PCS, including age, weight, gender, arthritides, plantar fasciitis and foot position; these factors may function as risk factors in PCS formation. The etiology of these spurs is a contentious issue and it has been explained through a number of theories including the degenerative, inflammatory, traction, repetitive trauma, bone-formers and vertical compression theories. We review these and finish by looking clinically at the evidence that PCS causes heel pain. © 2017 Anatomical Society.

To evaluate possible contribution of maturational delay of brain stem in the etiology of breath-holding spells in children using brain stem auditory evoked potentials. The study group included children who experienced breath-holding spells. The control group consisted of healthy age- and sex-matched children. Age, gender, type and frequency of spell, hemoglobin, and ferritin levels in study group and brain stem auditory evoked potentials results in both groups were recorded. Study group was statistically compared with control group for brain stem auditory evoked potentials. The mean age of study and control groups was 26.3 ± 14.6 and 28.9 ± 13.9 months, respectively. The III-V and I-V interpeak latencies were significantly prolonged in the study group compared with the control group (2.07 ± 0.2 milliseconds; 1.92 ± 0.13 milliseconds and 4.00 ± 0.27 milliseconds; 3.83 ± 0.19 milliseconds; P = 0.009 and P = 0.03, respectively). At the same time, III-V and I-V interpeak latencies of patients without anemia in the study group compared with those of control group were significantly prolonged (2.09 ± 0.24 milliseconds; 1.92 ± 0.13 milliseconds and 4.04 ± 0.28 milliseconds; 3.83 ± 0.19 milliseconds; P = 0.007 and P = 0.01, respectively). Our results consider that maturational delay in myelination of brain stem may have a role in the etiology of breath-holding spells in children.

Aims Culturally-specific lifestyle diabetes prevention programs require an assessment of population disease perceptions and cultural influences on health beliefs and behaviors. The primary objectives were to assess Arab Americans’ knowledge and perceptions of diabetes and their preferences for a lifestyle intervention. Methods Sixty-nine self-identified Arab or Arab Americans ≥ 30 years of age and without diabetes participated in 8 focus groups. Results Emerging themes from the data included myths about diabetes etiology, folk remedies, and social stigma. The main barrier to healthcare was lack of health insurance and/or cost of care. Intervention preferences included gender-specific exercise, group-delivered education featuring religious ideology, inclusion of the family, and utilization of community facilities. Conclusion Lifestyle interventions for Arab Americans need to address cultural preferences, diabetes myths, and folk remedies. Interventions should incorporate Arabic cultural content and gender-specific group education and exercise. Utilization of family support and religious centers will enable culturally-acceptable and cost-effective interventions. PMID:27460886

Objective Tinnitus is considered to be highly heterogeneous with respect to its etiology, its comorbidities and the response to specific interventions. Subtyping is recommended, but it remains to be determined which criteria are useful, since it has not yet been clearly demonstrated whether and to which extent etiologic factors, comorbid states and interventional response are related to each other and are thus applicable for subtyping tinnitus. Analyzing the Tinnitus Research Initiative Database we differentiated patients according to presence or absence of comorbid temporomandibular joint (TMJ) disorder complaints and compared the two groups with respect to etiologic factors. Methods 1204 Tinnitus patients from the Tinnitus Research Initiative (TRI) Database with and without subjective TMJ complaints were compared with respect to demographic, tinnitus and audiological characteristics, questionnaires, and numeric ratings. Data were analysed according to a predefined statistical analysis plan. Results Tinnitus patients with TMJ complaints (22% of the whole group) were significantly younger, had a lower age at tinnitus onset, and were more frequently female. They could modulate or mask their tinnitus more frequently by somatic maneuvers and by music or sound stimulation. Groups did not significantly differ for tinnitus duration, type of onset (gradual/abrupt), onset related events (whiplash etc.), character (pulsatile or not), hyperacusis, hearing impairment, tinnitus distress, depression, quality of life and subjective ratings (loudness etc.). Conclusion Replicating previous work in tinnitus patients with TMJ complaints, classical risk factors for tinnitus like older age and male gender are less relevant in tinnitus patients with TMJ complaints. By demonstrating group differences for modulation of tinnitus by movements and sounds our data further support the notion that tinnitus with TMJ complaints represents a subgroup of tinnitus with clinical features that are highly relevant for specific therapeutic management.

Introduction Current guidelines state that patients with severe mitral regurgitation should be treated in reference centers with a high reparability rate, low mortality rate, and durable results. Objective To analyze our global experience with the treatment of organic mitral regurgitation from various etiologies operated in a single center. Methods We evaluated all surgically treated patients with organic mitral regurgitation from 2004-2017. Patients were evaluated clinically and by echocardiography every year. We determined early and late survival rates, valve related events and freedom from recurrent mitral regurgitation and tricuspid regurgitation. Valve failure was defined as any mitral regurgitation ≥ moderate degree or the need for reoperation for any reason. Results Out of 133 patients with organic mitral regurgitation, 125 (93.9%) were submitted to valve repair. Mean age was 57±15 years and 52 patients were males. The most common etiologies were degenerative disease (73 patients) and rheumatic disease (34 patients). Early mortality was 2.4% and late survival was 84.3% at 10 years, which are similar to the age- and gender-matched general population. Only two patients developed severe mitral regurgitation, and both were reoperated (95.6% at 10 years). Freedom from mitral valve failure was 84.5% at 10 years, with no difference between degenerative and rheumatic valves. Overall, late ≥ moderate tricuspid regurgitation was present in 34% of the patients, being more common in the rheumatic ones. The use of tricuspid annuloplasty abolished this complication. Conclusion We have demonstrated that mitral regurgitation due to organic mitral valve disease from various etiologies can be surgically treated with a high repair rate, low early mortality and long-term survival that are comparable to the matched general population. Concomitant treatment of atrial fibrillation and tricuspid valve may be important adjuncts to optimize long-term results. PMID:29617498

The epidemiologic features of status epilepticus (SE) are still in the course of definition. We carried out an intensive survey of multiple sources of case material in the resident population of the health district of Ferrara, Italy, in 2003. Information was collected on age, gender, duration, seizure type and etiology of SE. The age- adjusted annual incidence rate of SE was 27.2/100,000 (95% CI = 19.4-36.9) and it was higher in men (41.7/100,000, 95% CI = 26.9-61.7) than in women (12.3/100,000, 95% CI = 6.9-20.4). The incidence was higher in the elderly (older than 60 years, 39.2/100,000) than in younger adults in the age group 20-59 years (14.7/100,000). The age-specific incidence showed a bimodal distribution peaking in the youngest (0-4 years) and in the oldest age group (75+ years). Cerebrovascular disease was the most frequent etiologic factor (45%). Epilepsy had previously been diagnosed in 40% of the patients. The case fatality was 5%. The study found a higher incidence of SE than that expected on the basis of the previous European studies suggesting that the risk of SE in southern Europe is higher and more similar to that estimated in population studies in the United States. The case fatality was lower than that reported in previous South-European population studies despite the similar clinical features of the patients. Indirect evidence suggests that several factors related to the SE management could have positively influenced the outcome. Copyright 2007 S. Karger AG, Basel.

Based on a number of small observational studies, cerebral venous sinus thrombosis has diverse clinical and imaging features, risk factors, and variable outcome. In a large, multicenter cerebral venous thrombosis (VENOST) study, we sought to more precisely characterize the clinical characteristics of Caucasian patients. All data for the VENOST study were collected between the years 2000 and 2015 from the clinical follow-up files. Clinical and radiological characteristics, risk factors, and outcomes were compared in terms of age and sex distribution. Among 1144 patients 68% were women, and in older age group (>50 years) male patients were more prevalent (16.6% versus 27.8%). The most frequent symptoms were headache (89.4%) and visual field defects (28.9%) in men, and headache (86.1%) and epileptic seizures (26.8%) in women. Gynecological factors comprised the largest group in women, in particular puerperium (18.3%). Prothrombotic conditions (26.4%), mainly methylenetetrahydrofolate reductase mutation (6.3%) and Factor V Leiden mutation (5.1%), were the most common etiologies in both genders. 8.1% of patients had infection-associated and 5.2% had malignancy-related etiology that was significantly higher in men and older age group. Parenchymal involvement constitutively hemorrhagic infarcts, malignancy, and older age was associated with higher Rankin score. Epileptic seizures had no effect on prognosis. Clinical and radiological findings were consistent with previous larger studies but predisposing factors were different with a higher incidence of puerperium. Oral contraceptive use was not a prevalent risk factor in our cohort. Malignancy, older age, and hemorrhagic infarcts had worse outcome. Copyright © 2017 National Stroke Association.

To review the methodology of behavior genetics studies addressing research questions that go beyond simple heritability estimation and illustrate these using representative research on childhood and adolescent anxiety and depression. The classic twin design and its extensions may be used to examine age and gender differences in the genetic determinants of complex traits and disorders, the role of genetic factors in explaining comorbidity, the interaction of genes and the environment, and the effect of social interaction among family members. An overview of the methods typically employed to address such questions is illustrated by a review of 34 recent studies on childhood anxiety and depression. The review provides relatively consistent evidence for small to negligible sex differences in the genetic etiology of childhood anxiety and depression, a substantial role of genetic factors in accounting for the temporal stability of these disorders, a partly genetic basis of the comorbidity between anxiety and depression, a possible role of the interaction between genotype and the environment in affecting liability to these disorders, a role of genotype-environment correlation, and a minor, if any, etiological role of sibling interaction. The results clearly demonstrate a role for genetic factors in the etiology and temporal stability of individual differences in childhood anxiety and depression. Clinical implications of the findings are discussed. 2010 American Academy of Child and Adolescent Psychiatry. Published by Elsevier Inc. All rights reserved.

Gender Dysphoria is a distressed state of mind that is of interest to psychiatrists, including forensic psychiatrists. Forensic matters can be best addressed only after one has a good appreciation of relevant psychiatric knowledge and concepts. In this commentary I review the nature of Gender Dysphoria, its relationship to cross-dressing and erotic arousal, and the question of whether it should be thought of as a psychiatric disorder. I also review the complexity of sex and gender; alternative conceptualizations of Gender Dysphoria, its etiology, its multicultural history, and its typical course over time in a given individual. Finally, I summarize treatment options, treatment outcomes, and difficulties of treating Gender Dysphoria within an inmate population. © 2016 American Academy of Psychiatry and the Law.

Despite the widely held belief that men are more narcissistic than women, there has been no systematic review to establish the magnitude, variability across measures and settings, and stability over time of this gender difference. Drawing on the biosocial approach to social role theory, a meta-analysis performed for Study 1 found that men tended to be more narcissistic than women (d = .26; k = 355 studies; N = 470,846). This gender difference remained stable in U.S. college student cohorts over time (from 1990 to 2013) and across different age groups. Study 1 also investigated gender differences in three facets of the Narcissistic Personality Inventory (NPI) to reveal that the narcissism gender difference is driven by the Exploitative/Entitlement facet (d = .29; k = 44 studies; N = 44,108) and Leadership/Authority facet (d = .20; k = 40 studies; N = 44,739); whereas the gender difference in Grandiose/Exhibitionism (d = .04; k = 39 studies; N = 42,460) was much smaller. We further investigated a less-studied form of narcissism called vulnerable narcissism-which is marked by low self-esteem, neuroticism, and introversion-to find that (in contrast to the more commonly studied form of narcissism found in the DSM and the NPI) men and women did not differ on vulnerable narcissism (d = -.04; k = 42 studies; N = 46,735). Study 2 used item response theory to rule out the possibility that measurement bias accounts for observed gender differences in the three facets of the NPI (N = 19,001). Results revealed that observed gender differences were not explained by measurement bias and thus can be interpreted as true sex differences. Discussion focuses on the implications for the biosocial construction model of gender differences, for the etiology of narcissism, for clinical applications, and for the role of narcissism in helping to explain gender differences in leadership and aggressive behavior. Readers are warned against overapplying small effect sizes to perpetuate gender stereotypes. PsycINFO Database Record (c) 2015 APA, all rights reserved.

To determine the role of lymph node biopsy in the diagnosis of lymphadenopathy and to find out the pattern of different diseases in relation to age, gender, and the site of lymph nodes involved. This retrospective study was carried out at the Histopathology Department of the Children's Hospital and The Institute of Child Health, Lahore, Pakistan, over a period of 9 years, from January 1999 to December 2007. Tissue samples were collected from 898 children presenting with lymphadenopathy, and the diagnosis was confirmed on histology and through various specific tests. The clinical data of the patients were collected from computerized hospital records. Among the total 898 consecutive lymph node biopsies, the most common pathology encountered was reactive hyperplasia in 356 children (39.6%), followed by tuberculosis in 262 (29.1%) and malignant lymphomas in 132 children (14.6%). The rest of the lesions include; 72 cases of granulomatous lymphadenitis (8%), 13 of histiocytosis X (1.4%), 44 (4.9%) of metastatic tumors, 16 of chronic inflammation (1.8%), and 3 cases of Kikuchi's disease (0.3%). The cause of lymphadenopathy was found to be significantly associated with age, gender, and site of the lymph nodes involved. Lymphadenopathy is a relatively common condition in the pediatric age group. Although 39.6% of children had reactive hyperplasia of unknown etiology, 60.3% children presented with a specific diagnosis.

Rethinking gender, heterosexual men, and women's vulnerability to HIV/AIDS.

Most HIV prevention literature portrays women as especially vulnerable to HIV infection because of biological susceptibility and men's sexual power and privilege. Conversely, heterosexual men are perceived as active transmitters of HIV but not active agents in prevention. Although the women's vulnerability paradigm was a radical revision of earlier views of women in the epidemic, mounting challenges undermine its current usefulness. We review the etiology and successes of the paradigm as well as its accruing limitations. We also call for an expanded model that acknowledges biology, gender inequality, and gendered power relations but also directly examines social structure, gender, and HIV risk for heterosexual women and men.

The aim of the study was to identify and quantify risk factors for hip pain. A representative sample of 5001 Danish men and women aged 18-65 years in 1990 were interviewed about occupational exposures (response rate 90%); 5 years later they were reinterviewed about hip pain (response rate 86%). Logistic regression with forced entry of all the independent variables was used to estimate the odds ratios for the possible risk factors. The impact of the various predictors was assessed through the calculation of population etiologic fractions. A double risk of hip pain was found for the women as compared with the men [odds ratio (OR) 2.28, 95% confidence interval (95% CI) 1.68-3.09]. The risk increased with body mass index. Whole-body vibration (OR 1.86, 95% CI 1.09-2.71) and physically demanding work (OR 1.83, 95% CI 1.23-2.71) were strong predictors of hip pain, while a squatting work posture was protective (OR 0.64, 95% CI 0.42-0.98). The impact of the statistically significant predictors (the etiologic fractions) was as follows: 0.49 for body mass index, 0.05 for whole body vibration, 0.10 for physically demanding work, and 0.32 for squatting (preventive). Female gender, age, high body mass index, whole-body vibration, and physically demanding work are significant risk factors for hip pain.

Hands are frequent sites of burn but few related studies were reported in China. The aim of this study was to examine the impacts of gender, age, seasons, place, etiology, total body surface area (TBSA), depth, infection and comorbidities on prognosis following injury in a cohort of hand burn inpatients. This is a retrospective study of total 378 inpatients admitted to the burn center of Changhai hospital from January 2009 to December 2013. The present research showed the male inpatients were predominant and most of the inpatients aged from 20 to 49. Flame (37.04%) and electricity (25.40%) were the major causes of hand burns. Hand burns happened more commonly in work place (60.85%). The study preliminarily pointed out that male, flame and depth were the most significant factors impacting surgery. The main factors relevant to amputation were identified including the electrical burns and other etiology of burns. In addition, depth of hand burns was proved to have a higher impact on length of hospital stay (LOS) than other factors. The results of this study not only provide the necessary information of hand burns in Eastern China but also give the suggestions for the prevention of hand burns.

It has been reported that borderline personality related characteristics can be observed in children, and that these characteristics are associated with increased risk for the development of borderline personality disorder. It is not clear whether borderline personality related characteristics in children share etiological features with adult borderline personality disorder. We investigated the etiology of borderline personality related characteristics in a longitudinal cohort study of 1,116 pairs of same-sex twins followed from birth through age 12 years. Borderline personality related characteristics measured at age 12 years were highly heritable, were more common in children who had exhibited poor cognitive function, impulsivity, and more behavioral and emotional problems at age 5 years, and co-occurred with symptoms of conduct disorder, depression, anxiety, and psychosis. Exposure to harsh treatment in the family environment through age 10 years predicted borderline personality related characteristics at age 12 years. This association showed evidence of environmental mediation and was stronger among children with a family history of psychiatric illness, consistent with diathesis–stress models of borderline etiology. Results indicate that borderline personality related characteristics in children share etiological features with borderline personality disorder in adults and suggest that inherited and environmental risk factors make independent and interactive contributions to borderline etiology.

This study analyzed eating disorder (ED) etiological factors for 100 midlife women ED inpatients, grouped by ED onset age: < 40 and > or = 40 years. Interpretative Phenomenological Analysis classified ED etiological influences into background contributors, immediate triggers, or sustainers. Family-of-origin issues, predominantly parental maltreatment, emerged as important background contributors, but not immediate ED triggers, regardless of onset age. Body image issues were also major background contributors regardless of onset age and further served as immediate ED triggers for many of the younger-onset patients, but not the older-onset patients. Family-of-choice and health issues were unimportant for younger-onset patients but were important ED contributors and triggers for older-onset patients. Emergent etiological differences suggest differential assessment and treatment needs for midlife ED patients based on ED onset age.

Autistic disorder (AD) is a complex neurodevelopmental disorder. The role of genetics in AD etiology is well established, and it is postulated that anywhere from 2 to 10 genes could be involved. As part of a larger study to identify these genetic effects we have ascertained a series of AD families: Sporadic (SP, 1 known AD case per family and no known history of AD) and multiplex (MP, > or = 2 cases per family). The underlying etiology of both family types is unknown. It is possible that MP families may constitute a unique subset of families in which the disease phenotype is more likely due to genetic factors. Clinical differences between the two family types could represent underlying genetic heterogeneity. We examined ADI-R data for 69 probands from MP families and 88 from SP families in order to compare and contrast the clinical phenotypes for each group as a function of verbal versus nonverbal status. Multivariate analysis controlling for covariates of age at examination, gender, and race (MANCOVA) revealed no differences between either the verbal or nonverbal MP and SP groups for the three ADI-R area scores: social interaction, communication, and restricted/repetitive interests or behaviors. These data failed to find clinical heterogeneity between MP and SP family types. This supports previous work that indicated that autism features are not useful as tools to index genetic heterogeneity. Thus, although there may be different underlying etiologic mechanisms in the SP and MP probands, there are no distinct behavioral patterns associated with probands from MP families versus SP families. These results suggests the possibility that common etiologic mechanisms, either genetic and/or environmental, could underlie all of AD.

A model for critical review of literature - with vaginismus as an example.

2007-03-01

In this article we present a behavioral model for the critical review of the literature within a certain research field, using vaginismus as an example. We searched the literature for the title word "vaginismus" and analyzed to what extent the articles dealt with the following seven categories: prevention, etiology, maintaining factors, consequences, object of intervention, method of intervention, and method of evaluation. In each category we scrutinized the content of the articles for biological, psychological, social, relational, and gender aspects. Quality requirements of etiological and treatment studies were then added and the results presented in a "quality-adjusted" model. There were 102 articles during 1985-2001, of which 22 were included in the review. Most of the articles deal with supposed predisposing factors of etiology and different aspects of intervention. Only a few articles discuss precipitating factors, maintaining factors, or consequences of the problem. No article had a gender analysis. Only 11 of the articles fulfilled some of the proposed quality criteria. We found the behavioral model with quality requirements useful for classifying and evaluating the literature of vaginismus. The model may also be used as a guide to design methodologically good studies.

Aggressive Versus Nonaggressive Antisocial Behavior: Distinctive Etiological Moderation by Age

2015-01-01

Research has supported the existence of distinct behavioral patterns, demographic correlates, and etiologic mechanisms for aggressive (AGG) versus nonaggressive but delinquent (DEL) antisocial behavior. Though behavioral genetic studies have the potential to further crystallize these dimensions, inconsistent results have limited their contribution. These inconsistencies may stem in part from the limited attention paid to the impact of age. In the current study, the authors thus examined age-related etiological moderation of AGG and DEL antisocial behavior in a sample of 720 sibling pairs (ranging in age from 10 to 18 years) with varying degrees of genetic relatedness. Results reveal that the magnitude of genetic and environmental influences on AGG remained stable across adolescence. By contrast, genetic influences on DEL increased dramatically with age, whereas shared environmental influences decreased. Subsequent longitudinal analyses fully replicated these results. Such findings highlight etiological distinctions between aggression and delinquency, and offer insights into the expression of genetic influences during development. PMID:19586186

For many years, gender differences have been recognized as important factors in the etiology, pathophysiology, comorbidities, and treatment needs and outcomes associated with the use of alcohol, drugs, and tobacco. However, little is known about how these gender-specific differences affect ED utilization; responses to ED-based interventions; needs for substance use treatment and barriers to accessing care among patients in the ED; or outcomes after an alcohol-, drug-, or tobacco-related visit. As part of the 2014 Academic Emergency Medicine consensus conference on “Gender-Specific Research in Emergency Care: Investigate, Understand and Translate How Gender Affects Patient Outcomes,” a breakout group convened to generate a research agenda on priority questions related to substance use disorders.

Objectives. Guided by the life-course perspective, we examined whether there were subgroups with different likelihood curves of smoking onset associated with specific developmental periods. Methods. Using 12 waves of panel data from 4088 participants in the National Longitudinal Survey of Youth 1997, we detected subgroups with distinctive risk patterns by employing developmental trajectory modeling analysis. Results. From birth to age 29 years, 72% of female and 74% of US males initiated smoking. We detected 4 exclusive groups with distinctive risk patterns for both genders: the Pre-Teen Risk Group initiated smoking by age 12 years, the Teenage Risk Group initiated smoking by age 18 years, the Young Adult Risk Group initiated smoking by age 25 years, and the Low Risk Group experienced little or no risk over time. Groups differed on several etiological and outcome variables. Conclusions. The process of smoking initiation from birth to young adulthood is nonhomogeneous, with distinct subgroups whose risk of smoking onset is linked to specific stages in the life course. PMID:24328611

Chronic liver disease (CLD) starts or becomes established in the adolescent and young adult (AYA) age group. This study aimed to estimate trends in CLD prevalence among US AYAs and to assess factors associated with CLD. Cross-sectional data from 14,547 AYAs (population-weighted N = 68,274,386) aged 15-39 years enrolled in the National Health and Nutrition Examination Survey from 1988 to 2012 were used. Nonalcoholic fatty liver disease (NAFLD) was defined as elevated alanine aminotransferase (>19 U/L for females and >30 U/L for males) in subjects with BMI ≥ 25 kg/m 2 ; alcoholic liver disease (ALD) as excessive alcohol use (≥3 drinks/day for men and ≥2 drinks/day for women) and elevated aminotransferases after excluding alternative etiologies. Participants were considered hepatitis C virus (HCV) positive if antibody to HCV and HCV-RNA was positive. There was a sharp increase in the prevalence of CLD from 12.9% in 1988-1994 to 28.5% in 1999-2004 that remained stable after that (27.7%). NAFLD was the most common etiology accounting for 22% of all CLD in the later period. The prevalence of ALD has been steadily increasing throughout the years, while HCV has been decreasing. On multivariate analysis, being overweight/obese, Mexican-American ethnicity, later study period, older age, and male gender, were associated with higher odds of having CLD. More than one quarter of US AYAs might be affected by CLD. CLD prevalence in this age group has more than doubled over the past three decades mainly due to rise in NAFLD prevalence.

Differences in clinicopathological characteristics of gastric cancer (GC) between young and older patients are controversial and a matter of debate. Determining the statistical significance of clinicopathological information with respect to age might provide clues for better management and treatment of GC. A total of 103 Indian GC patients were enrolled for study and specimens were classified according to the AJCC-TNM system. Patients were grouped into two age-wise categories, young patients (<40 years; n=13) and older patients (≥40 years, n=90). The clinicopathological features of both groups were retrospectively examined and compared. p53 alterations were analyzed by polymerase chain reaction-single strand conformational polymorphism and immunohistochemistry methods at gene and protein levels respectively. The cases were considered p53 over-expressed if it was present in more than 25% of the tumor cells and p53 alterations was correlated with the clinicopathological characteristics of the patients as well as etiological factors for GC in both groups. We found significant association of young patients with cancer stage (p=0.01), and very strong association with histology grade (p=0.064) and poorly differentiated (p=0.051) state of GC. However, neither young nor elderly patients showed associations with location, gender, etiological factors and p53 expression and alteration. Overall the male-to-female ratio of GC patients was 3.12 and the value was higher in the young (5.5) than in the older group (2.91). Clinicopathological features of GC like cancer stage, cell differentiation and histological grades were significantly different among young and old age cohorts. We observed a male predominance among the young group that decreased significantly with advancing age. More awareness of GC onset is required to detect cancer at an early stage for successful treatment.

The objective of this study was to evaluate the frequency, severity, exact patterns and mechanisms of burn injuries in children. The patient records of children with acute burns admitted to the University Children's Hospital of Zurich were retrospectively reviewed over an 11year period. The age group with the highest risk, were children under the age of five (69%). Boys were overrepresented in all age groups, but the gender imbalance increased with age. Infants and toddlers were mainly injured by scalds and contact burns. Conversely, almost three quarters of injuries over the age of 9 were caused by flame. The majority of scald injuries was a result of pulling down hot liquids. The typical distribution of this accident scenario involved mainly the face, trunk and arms. More than half of all flame injuries occurred due to fire accelerants. 55% of children were passively involved while other children throwing flammable substances into a fire. Most of these injuries involved the face and arms. This study shows that burn etiology is age dependent. Additionally, our results demonstrate the diversity of burn accidents and their resulting injuries. These findings may help better specify target groups and subjects for prevention.

Back pain has remained an issue of significance among aircraft crewmembers for decades, occurring in the majority of military helicopter pilots with potential deleterious effects on performance, safety, and operational readiness. This exploratory, correlational survey study was designed to evaluate the presence of patterns and relationships that may require further examination to understand causal factors. The study population consisted of U.S. Army aviation crewmembers. Subjects (467) completed an anonymous survey, including questions regarding demographics, airframes, experience, pain history and severity, ergonomics, mitigation strategies, and duty limitations. Overall, 84.6% of participants reported back pain at some time during their flying career, with 77.8% reporting back pain in the last calendar year. Age was found to significantly correlate with earlier time to pain during flight, higher pain rating after flight, and occurrence of grounding. A stepwise linear regression model was used to explore the relationships between age, flight hours, and years of aviation experience, demonstrating age to be the significant variable accounting for the observed variance. Aircrew reported wear of combat-related survival equipment and poor lumbar support to be the most notable contributors. Back pain rates were consistent with previous studies. The relationship of age to back pain in this study may highlight unique pathophysiological pathways that should be further investigated within an occupational context to better understand the etiologic role. Enhanced seated lumbar support and combat-related survival equipment remain relatively low-cost/high-yield topics worthy of further investigation for exploiting efficient means to improve health, safety, and operational performance.Kelley AM, MacDonnell J, Grigley D, Campbell J, Gaydos SJ.

Several lines of evidence have implicated the pro-inflammatory cytokine interleukin-1beta (IL-1β) in the etiology of schizophrenia. Although a number of genetic association studies have been reported, very few have systematically examined gene-wide tagging polymorphisms. A total of 533 patients with schizophrenia (302 males: mean age ± standard deviation 43.4 ± 13.0 years; 233 females; mean age 44.8 ± 15.3 years) and 1136 healthy controls (388 males: mean age 44.6 ± 17.3 years; 748 females; 46.3 ± 15.6 years) were recruited for this study. All subjects were biologically unrelated Japanese individuals. Five tagging polymorphisms of IL-1β gene (rs2853550, rs1143634, rs1143633, rs1143630, rs16944) were examined for association with schizophrenia. Significant difference in allele distribution was found between patients with schizophrenia and controls for rs1143633 (P = 0.0089). When the analysis was performed separately in each gender, significant difference between patients and controls in allele distribution of rs1143633 was observed in females (P = 0.0073). A trend towards association was also found between rs16944 and female patients with schizophrenia (P = 0.032). The present study shows the first evidence that the IL-1β gene polymorphism rs1143633 is associated with schizophrenia susceptibility in a Japanese population. The results suggest the possibility that the influence of IL-1β gene variations on susceptibility to schizophrenia may be greater in females than in males. Findings of the present study provide further support for the role of IL-1β in the etiology of schizophrenia.

Do students with Down syndrome have a specific learning profile for reading?

Ratz, Christoph

2013-12-01

The present study assessed achieved reading stages of 190 school-aged children with Down syndrome (DS, age 6-20) in Bavaria, one of the most populated federal states in Germany. Teachers described the reading stages of their students in a questionnaire. The achieved stages of reading according to the developmental model of Frith are compared to a sample of 1419 students with intellectual disability (ID) regardless of etiology, but excluding DS; thereafter parallelized ID-groups were compared. Results of the questionnaire addressed to the students' teachers showed that 20.2% of the students with DS do not read at all, 7.6% read at a logographic stage, 49.4% at an alphabetic and 22.8% at an orthographic level. Alongside these findings among the whole sample, correlations are described concerning age, gender, IQ and sociocultural background. The students with DS are then compared to other students with ID with mixed etiologies. This comparison stresses the emphasis on the alphabetic level amongst students with DS. This emphasis also exists when DS and non-DS students are parallelized in groups of ID, thus showing that students with DS and severe ID are ahead in reading, but those with mild ID are behind. Knowledge about specific literacy attainment of students with DS is vital for planning instruction, for creating learning environments, and for formulating future fields of research. Especially students with DS need specific teaching which takes their impaired verbal short term memory into account, such as learning to read in syllables. Copyright © 2013 Elsevier Ltd.

To understand the role of major, minor, and trace elements in the etiology of bone diseases including osteoporosis, it is necessary to determine the normal levels and age-related changes of bone chemical elements. The effect of age and gender on 38 chemical element contents in intact iliac crest of 84 apparently healthy 15-55 years old women (n=38) and men (n=46) was investigated by neutron activation analysis. Mean values (M+/-SEM) for mass fraction (on dry weight basis) of Ca, Cl, Co, Fe, K, Mg, Mn, Na, P, Rb, Sr, and Zn for both female and male taken together were Ca - 169+/-3g/kg, Cl - 1490+/-43 mg/kg, Co - 0.0073+/-0.0024 mg/kg, Fe - 177+/-24 mg/kg, K - 1820+/-79 mg/kg, Mg - 1840+/-48 mg/kg, Mn - 0.316+/-0.013 mg/kg, Na - 4970+/-87 mg/kg, P - 79.7+/-1.5 g/kg, Rb - 1.89+/-0.22 mg/kg, Sr - 312+/-15 mg/kg, and Zn - 65.9+/-3.4 mg/kg, respectively. The upper limit of mean contents of Cs, Eu, Hg, Sb, Sc, and Se were Cs < or = 0.09 mg/kg, Eu < or = 0.005 mg/kg, Hg < or = 0.005 mg/kg, Sb < or = 0.004 mg/kg, Sc < or = 0.001 mg/kg, and Se < or = 0.1mg/kg, respectively. In all bone samples the contents of Ag, As, Au, Ba, Br, Cd, Ce, Cr, Gd, Hf, La, Lu, Nd, Sm, Ta, Tb, Th, U, Yb, and Zr were under detection limits. The Ca, Mg, and P contents decrease with age, regardless of gender. Higher Ca, Mg, P, and Sr mass fractions as well as lower Fe content are typical of female iliac crest as compared to those in male bone. Copyright 2009 Elsevier GmbH. All rights reserved.

In a series of important but now highly controversial articles, Blanchard examined associations of sexual orientation and transvestic fetishism among male-to-female (MTF) transgender persons in Toronto, Canada. Transvestic fetishism was rare among the homosexuals but prevalent among the non-homosexuals. Subtypes of non-homosexual MTFs (heterosexual, bisexual, and asexual) were consistently high with regard to transvestic fetishism. Non-linear associations of a continuous measurement of sexual attraction to women (gynephilia) and transvestic fetishism were interpreted in terms of an etiological hypothesis in which transvestic fetishism interferes with the early development of heterosexuality. Blanchard concluded that homosexual versus non-homosexual sexual orientation is a dominant and etiologically significant axis for evaluating and understanding this population. We further assessed these findings among 571 MTFs from the New York City metropolitan area. Using the Life Chart Interview, multiple measurements of transvestic fetishism were obtained and classified as lifetime, lifecourse persistent, adolescent limited, and adult onset. Large (but not deterministic) differences in lifetime, lifecourse persistent, and adolescent limited transvestic fetishism were found between the homosexuals and non-homosexuals. Contrary to Blanchard, differences in transvestic fetishism were observed across subtypes of the non-homosexuals, and linear (not curvilinear) associations were found along a continuous measurement of gynephilia and transvestic fetishism. Age and ethnicity, in addition to sexual orientation, were found to be statistically significant predictors of transvestic fetishism. The clinical, etiological, and sociopolitical implications of these findings are discussed.

Using the Life Chart Interview, multiple measurements of transvestic fetishism were obtained and classified as lifetime, lifecourse persistent, adolescent limited, and adult onset. Large (but not deterministic) differences in lifetime, lifecourse persistent, and adolescent limited transvestic fetishism were found between the homosexuals and non-homosexuals. Contrary to Blanchard, differences in transvestic fetishism were observed across subtypes of the non-homosexuals, and linear (not curvilinear) associations were found along a continuous measurement of gynephilia and transvestic fetishism. Age and ethnicity, in addition to sexual orientation, were found to be statistically significant predictors of transvestic fetishism. The clinical, etiological, and sociopolitical implications of these findings are discussed. PMID:20039113

A wakeup call to the prevention field: are prevention programs for substance use effective for girls?

Substance misuse in adolescent girls has increased dramatically since 1992. This article reviews trends in use rates and etiological theories tested by gender that suggest that family protective factors have more influence on girls. Next, a literature review reveals that few prevention programs have published their outcomes by gender or developed gender-specific programs. Nationwide community coalition results found positive effects on boys but increased drug use in young girls. The most effective programs are family focused targeting family bonding, supervision, and communication. Recent gender-specific prevention programs with positive results address stress, depression, social assertiveness, and body image. The authors recommend additional research testing programs by gender and also gender-specific versus generic versions of evidence-based programs to determine how to improve prevention program effectiveness for girls.

Currently, a wide spectrum of retrospective studies regarding the incidence of TC among children and adults are available in the world literature, but none of them are comparative, aiming to distinguish etiological diversity depending on the different geographic areas. This study aimed to investigate the epidemiology of TC in Plovdiv, Bulgaria and Thessaloniki, and Greece, and to compare the results and predominant etiological agents using retrospective comparative analysis for an 11-year time period. The subjects included were selected from archives of the Mycological Laboratory of the University Dermatologic Clinic, University Hospital "St. George" Plovdiv, Bulgaria, and the Mycological Laboratory of the First Dermatology Department of Aristotle University Thessaloniki, Greece, by retrospective analysis of data from an 11-year time period (2004-2014). A total count of 374 children aged 0-18, with confirmed diagnosis of TC via direct mycological examination and culture were included (128 children from Plovdiv, Bulgaria, and 246 children from Thessaloniki, Greece). Samples were plated on Sabouraud agar, followed by species identification of the isolated colonies. Our results demonstrate that the incidence of TC in the region of Bulgaria and Thessaloniki for the investigated period was lower than for the previously reported period. In Plovdiv, Bulgaria, it was 1.20 ± 0.09 % (n = 172 from a total count of 14,278 cases of mycoses), as the disease accounts for 23.10 ± 1.79 % of all mycological infections among the pediatric population and 0.36 ± 0.05 % (n = 49 from a total count of 13,724) among the adults patients in Plovdiv, Bulgaria. The incidence of the disease during the period 2004-2014 in Thessaloniki was 2.49 ± 0.15 % (n = 253 cases of TC from a total count of 10,168 mycoses), as it accounts for approximately 27.06 ± 1.47 % of mycological infections among the pediatric population in Thessaloniki, Greece, and 0.08 ± 0.03 % (n = 7 from a total count of 9259) of the population of adult patients with mycoses. Our study confirmed the presumption that M. canis is the leader among the causative agents in TC in children in both of the included countries, but its presence in the etiology of disease in adult patients was very low and nonsignificant. We categorically identified dominance of the female gender among the children with TC in Plovdiv, Bulgaria; while in Thessaloniki, Greece, the gender distribution had an almost equal ratio of males to females. Our results suggest that the gender predisposition depends also on the investigated geographic region and the time of the study, rather than only on the causative pathogen and age.

Summary Background One third of patients who receive cardiac resynchronization therapy (CRT) are classified as nonresponders. Characteristics of responders to CRT have been studied in multiple clinical trials. Hypothesis We aimed to examine characteristics of CRT responders in a routine clinical practice. Method One hundred and twenty five patients were examined retrospectively from a multidisciplinary CRT clinic program. Echocardiographic CRT response was defined as a decrease in left ventricular (LV) end systolic volume (ESV) of ≥ 15% and/or absolute increase of 5% in LV ejection fraction (EF) at 6 month visit. Results There were 81 responders and 44 nonresponders. By univariate analyses, female gender, nonischemic cardiomyopathy etiology, baseline QRS duration, the presence of left bundle branch block (LBBB) and left ventricular end-diastolic volume (LVEDV) index predicted CRT response. However, multivariate analysis demonstrated only QRS duration, LBBB and LVEDV index were independent predictors (QRS width: Odd ratio [OR] 1.027, 95% CI 1.004 – 1.050, p = 0.023; LBBB: OR 3.568, 95% CI 1.284 – 9.910, p=0.015; LV EDV index: OR 0.970, 95% CI 0.953 – 0.987, p= 0.001). While female gender and nonischemic etiology were associated with an improved CRT response on univariate analyses, after adjusting for LV volumes, they were not independent predictors. Conclusion QRS width, LBBB and LVEDV index are independent predictors for echocardiographic CRT response. Previously reported differences in CRT response for gender and cardiomyopathy etiology are associated with differences in baseline LV volumes in our clinical practice. PMID:22886700

The etiology of idiopathic peripheral facial palsy (IPFP) is still uncertain; however, some authors suggest the possibility of a viral infection. to analyze the ultrastructure of the facial nerve seeking viral evidences that might provide etiological data. We studied 20 patients with peripheral facial palsy (PFP), with moderate to severe FP, of both genders, between 18-60 years of age, from the Clinic of Facial Nerve Disorders. The patients were broken down into two groups - Study: eleven patients with IPFP and Control: nine patients with trauma or tumor-related PFP. The fragments were obtained from the facial nerve sheath or from fragments of its stumps - which would be discarded or sent to pathology exam during the facial nerve repair surgery. The removed tissue was fixed in 2% glutaraldehyde, and studied under Electronic Transmission Microscopy. In the study group we observed an intense repair cellular activity by increased collagen fibers, fibroblasts containing developed organelles, free of viral particles. In the control group this repair activity was not evident, but no viral particles were observed. There were no viral particles, and there were evidences of intense activity of repair or viral infection.

Purpose: Cataract surgery is the most common intraocular surgery performed all over the world and has advanced technically in recent years. As in all surgeries, complications are unavoidable. Herein we report factors associated with complications and visual outcomes of cataract surgery. Methods: This retrospective cohort study included data of 1,632 cataract surgeries performed from 2007 to 2010 which was obtained from the cataract registry of the Malaysian National Eye Database. Demographic features, ocular and systemic comorbidites, grade of surgeon expertise and duration of surgery, type of anesthesia, intraoperative and postoperative complications, and the type of intraocular lens were recorded. Best corrected visual acuities were compared before and after the operation. Results: Mean patient age was 66.9 years with equal gender distribution. The majority of subjects had age related cataracts. Phacoemulsification was done faster than other surgeries, especially by specialist surgeons. History of prior ocular surgery and operations performed under general anesthesia were associated with greater complications. Phacoemulsification was associated with less complications and better visual outcomes. The age and etiology of cataract did not affect complications. Malays, absence of ocular comorbidities, left eyes and eyes operated under local anesthesia were more likely to experience more visual improvement. Gender, age, cause of cataract, systemic comorbidities and surgeon expertise as well as intra-and postoperative complications did not affect the visual outcomes. Conclusion: Phacoemulsification had good visual outcomes in cataract surgery. Duration of surgery, expertise of the surgeon and complications did not affect the visual outcomes. PMID:27051481

Abstract To investigate the incidence and pattern of patients managed for traumatic upper cervical spinal fractures (TUCSFs) in teaching hospitals in China over 13 years. We retrospectively reviewed 351 patients with TUCSF admitted to our teaching hospitals. Incidence rates were calculated with respect to age, gender, etiologies of trauma, anatomical distribution, anatomical classification, American spinal injury association impairment scale (ASIA) classification of neurological deficit and associated injuries. There were 260 male and 91 female patients, with a mean age of 44.2 ± 16.3 years. The mean age of the patients significantly increased by year of admission, from 35.2 ± 14.5 years to 47.5 ± 17.2 years (P = 0.005). Motor vehicle accidents (MVAs) (n = 132, 37.6%) and high falls (n = 104, 29.6%) were the 2 most common mechanisms. The number of C2 fractures (n = 300, 85.5%) was significantly higher than that of C1 (n = 99, 28.2%) (P < 0.001). High falls resulted in significantly more Type I C1 fractures than other etiologies (all P < 0.001). MVAs resulted in many more Type II and Type III C1 fractures and Type II and Type III C2 fractures than other etiologies. High falls were the most common injury type (n = 44, 36.4%) resulting in neurological deficits. Patients who presented with Landell classification Type I single C1 fracture (n = 6, 42.9%) had the highest rate of neurological deficits. Eighty-two patients had combined injuries; the most common pattern was cervical + cervical spine (n = 44, 12.5%), followed by cervical + thoracic spine (n = 27, 7.7%). A total of 121 patients (34.5%) suffered neurological deficits. Of all patients with TUCSF without combined injuries, single C2 fractures accounted for the highest rate of neurological deficits (n = 62, 32.0%). Multivariate logistic regression analysis indicated that sex (OR = 1.876, 95% CI: 1.022–3.443, P = 0.042), etiology (MVA pedestrians vs high fall: OR = 0.187, 95% CI: 0.056–0.629, P = 0.007), level (C1 + OFs vs C1: OR = 6.264, 95% CI: 1.152–34.045, P = 0.034), and injury severity scoring (ISS) (OR = 1.186, 95% CI: 1.133–1.242, P < 0.001) were independent risk factors of neurological deficit. The most common causes of TUCSF were MVAs and high falls; single C2 fractures without combined injuries accounted for the most common neurological deficits. Different etiologies resulted in different specific anatomical injuries and neurological deficits. We should make early diagnoses and initiate timely treatment according to different TUCSF patterns.

For many years, gender differences have been recognized as important factors in the etiology, pathophysiology, comorbidities, and treatment needs and outcomes associated with the use of alcohol, drugs, and tobacco. However, little is known about how these gender-specific differences affect ED utilization; responses to ED-based interventions; needs for substance use treatment and barriers to accessing care among patients in the ED; or outcomes after an alcohol-, drug-, or tobacco-related visit. As part of the 2014 Academic Emergency Medicine consensus conference on "Gender-Specific Research in Emergency Care: Investigate, Understand and Translate How Gender Affects Patient Outcomes," a breakout group convened to generate a research agenda on priority questions related to substance use disorders. © 2014 by the Society for Academic Emergency Medicine.

2017-02-01

Culturally-specific lifestyle diabetes prevention programs require an assessment of population disease perceptions and cultural influences on health beliefs and behaviors. The primary objectives were to assess Arab Americans' knowledge and perceptions of diabetes and their preferences for a lifestyle intervention. Sixty-nine self-identified Arab or Arab Americans ≥30 years of age and without diabetes participated in 8 focus groups. Emerging themes from the data included myths about diabetes etiology, folk remedies, and social stigma. The main barrier to healthcare was lack of health insurance and/or cost of care. Intervention preferences included gender-specific exercise, group-delivered education featuring religious ideology, inclusion of the family, and utilization of community facilities. Lifestyle interventions for Arab Americans need to address cultural preferences, diabetes myths, and folk remedies. Interventions should incorporate Arabic cultural content and gender-specific group education and exercise. Utilization of family support and religious centers will enable culturally-acceptable and cost-effective interventions. Copyright © 2016 Primary Care Diabetes Europe. Published by Elsevier Ltd.

Objective Bladder carcinoma (BC) is the fourth most common type of cancer in males from Western countries, with primary prevention an important healthcare challenge. We review the associated constitutional and occupational risk factors (RF), with greater or lesser scientific evidence, in the etiology of BC. Material and methods Literature review of the last 25 years of the constitutional and occupational RF associated with BC, conducted on MedLine, CancerLit, Science Citation Index and Embase. The search profiles were Risk factors/Genetic factors/Genetic polymorphisms/Epidemiology/Occupational factors and Bladder cancer. Results The main RF were (a) age and gender (diagnosed at age 65 and over, with a 4:1 ratio of males to females); (b) race, ethnicity and geographic location (predominantly in Caucasians and in Southern European countries); (c) genetic (N-acetyltransferase-2 and glutathione s-transferase M1 gene mutations, which significantly increase the risk for BC); (d) occupational, which represent 5–10% of BC RF; and (f) occupations with high BC risk, such as aluminum production, the manufacture of dyes, paints and colourings, the rubber industry and the extraction and industrial use of fossil fuels. Conclusions BC is the end result of the variable combination of constitutional and environmental RF, the majority of which are unknown. The most significant constitutional RF are related to age, gender, race, ethnicity geographic location and genetic polymorphisms. The main occupational RF are those related to aromatic amines and polycyclic aromatic hydrocarbons. PMID:23664103

Determining the association of age and laboratory parameters with tumor size of hepatocellular carcinoma (HCC). The study was at Adam Malik Hospital Medan from June- December 2016. 100 HCC patients were enrolled; those with excluding liver metastatic. Baseline characteristics of gender, age, obtaining etiology of HCC. Liver function tests, viral marker, and INR were done. Based on tumor size from abdomen CT, patients were three groups: tumor size below 3 cm, 3-5 cm, and above 5 cm size. Patients were also divided based on Child-Pugh class. Correlation of age and laboratory results with tumor size of HCC patients were analyzed. Age have negative correlation with tumor size in HCC patients (r=-0.297, p=0.032) while AFP have positive correlation with tumor size (r0.446, p=<0.001). Total bilirubin, AST, and ALT have negative correlation but non-significant (r=-0.045, -0.078, - 0.126 respectively). Albumin and INR have positive correlation but non-significant (r=0.021, 0.112 respectively). Our study suggests that older age correlates with smaller tumor size, while AFP level has a significant correlation with tumor size in HCC patients. AFP level may be a useful marker for determining the prognosis of HCC patients.

Hematoma of the ligamentum flavum (LF) is a rare cause of neural compression and sciatica. Currently, the etiology and epidemiological characteristics of ligamentum flavum hematoma (LFH) are unknown and epidemiological investigations using rewieving of reported cases have not been performed. We report the case of a 63-year-old man with a LFH compressing the spinal canal at the left L2-L3 level, rewieved relevant literature. In Medline research, wefound a total of 50 reported cases with LFHs, and the interesting point of these cases were analyzed. Many of cases were old males. Interestingly, 39 of the 50 cases were reported from Asian countries. The ages of 42 patients could be verified. The youngest age was 45 years, oldest age was 81 years, and mean age was 66.07 years. Thirty-three out of these 42 patients (78.53%) were older than 60 years. An important aspect of the present review is to bring attention for occurrence in older Asian males. With an increasing number of elderly people in the general population, there is a need to investigate risk factors such as sexual gender, age, and geographic location for LFH.

The etiology and natural history of T1DM are still unknown but certainly both genetics and environmental factors contribute to the development of the disease. Migration studies are an important tool to better understand the role of the environment. The aim of this study was to investigate some variables in diabetic children of immigrant families living in Emilia-Romagna compared with Italian diabetic children living in the same region. We recruited 73 diabetic children from immigrant families and 707 Italian diabetic children. All children were cared by Pediatric Diabetes Units of Emilia-Romagna (10 centers). The investigated variables were: gender, current age, place of birth, parents' country of origin, age at diagnosis, HbA1c and insulin regimen. No significant difference with reference to gender neither among the two ethnic groups, nor in the current mean age was observed. Mean age at diagnosis in the Italian children was lower than in immigrant patients born outside Italy--group A- (7.4 vs. 9.6, p < 0.000) and higher compared to those born in Italy--group B- (7.4 vs. 5.7 p < 0.003; A vs. B p < 0.000). The immigrant patients showed higher mean HbA1c than Italian patients (8.8 vs. 8.2, p < 0.009). A younger age at diagnosis of T1DM in immigrant children, born in Italy compared with those born in the country of origin, and with Italian patients, suggests the existence of some environmental determinants acquired with a more westernised lifestyle. Immigrant children have significantly poorer metabolic control compared with western patients. (www.actabiomedica.it)

Spoken language outcomes after hemispherectomy: factoring in etiology.

We analyzed postsurgery linguistic outcomes of 43 hemispherectomy patients operated on at UCLA. We rated spoken language (Spoken Language Rank, SLR) on a scale from 0 (no language) to 6 (mature grammar) and examined the effects of side of resection/damage, age at surgery/seizure onset, seizure control postsurgery, and etiology on language development. Etiology was defined as developmental (cortical dysplasia and prenatal stroke) and acquired pathology (Rasmussen's encephalitis and postnatal stroke). We found that clinical variables were predictive of language outcomes only when they were considered within distinct etiology groups. Specifically, children with developmental etiologies had lower SLRs than those with acquired pathologies (p =.0006); age factors correlated positively with higher SLRs only for children with acquired etiologies (p =.0006); right-sided resections led to higher SLRs only for the acquired group (p =.0008); and postsurgery seizure control correlated positively with SLR only for those with developmental etiologies (p =.0047). We argue that the variables considered are not independent predictors of spoken language outcome posthemispherectomy but should be viewed instead as characteristics of etiology.

Transsexualism: a review of etiology, diagnosis and treatment.

PubMed

Cohen-Kettenis, P T; Gooren, L J

1999-04-01

Transsexualism is considered to be the extreme end of the spectrum of gender identity disorders characterized by, among other things, a pursuit of sex reassignment surgery (SRS). The origins of transsexualism are still largely unclear. A first indication of anatomic brain differences between transsexuals and nontranssexuals has been found. Also, certain parental (rearing) factors seem to be associated with transsexualism. Some contradictory findings regarding etiology, psychopathology and success of SRS seem to be related to the fact that certain subtypes of transsexuals follow different developmental routes. The observations that psychotherapy is not helpful in altering a crystallized cross-gender identity and that certain transsexuals do not show severe psychopathology has led clinicians to adopt sex reassignment as a treatment option. In many countries, transsexuals are now treated according to the Standards of Care of the Harry Benjamin International Gender Dysphoria Association, a professional organization in the field of transsexualism. Research on postoperative functioning of transsexuals does not allow for unequivocal conclusions, but there is little doubt that sex reassignment substantially alleviates the suffering of transsexuals. However, SRS is no panacea. Psychotherapy may be needed to help transsexuals in adapting to the new situation or in dealing with issues that could not be addressed before treatment.

Research addressing genetic and environmental determinants to antisocial behaviour suggests substantial variability across studies. Likewise, evidence for etiologic gender differences is mixed, and estimates might be biased due to assortative mating. We used longitudinal Swedish total population registers to estimate the heritability of objectively measured violent offending (convictions) in classic twin (N = 36,877 pairs), adoptee-parent (N = 5,068 pairs), adoptee-sibling (N = 10,610 pairs), and sibling designs (N = 1,521,066 pairs). Type and degree of assortative mating were calculated from comparisons between spouses of siblings and half-siblings, and across consecutive spouses. Heritability estimates for the liability of violent offending agreed with previously reported heritability for self-reported antisocial behaviour. While the sibling model yielded estimates similar to the twin model (A ≈ 55%, C ≈ 13%), adoptee-models appeared to underestimate familial effects (A ≈ 20-30%, C ≈ 0%). Assortative mating was moderate to strong (r (spouse) = 0.4), appeared to result from both phenotypic assortment and social homogamy, but had only minor effect on variance components. Finally, we found significant gender differences in the etiology of violent crime.

The attention of international agencies and scientific community on mobbing (bullying) and work-related stress is increasing. However, research on gender differences and etiologic agents is still limited. This study describes the gender differences found in victims of mobbing and work-related stress in an Italian case series. Between 2001 and 2009, at the Occupational Medicine Unit of our Institution we examined 345 outpatients (197 women and 148 men) for suspected psychopathological work-related problems. After interdisciplinary diagnostic evaluation, the diagnosis of "mobbing syndrome" was formulated, according to international criteria (ICD-I0 and DSM-IV), in a minority of cases: 35 subjects. In the other workers, we found pre-existing psychiatric conditions (not related to work), or altered relationships dynamics with the colleagues. Significant gender differences emerged among people with "mobbing syndrome": there was a high prevalence of women (65%), with medium to high level of education; the most affected age group was between 34 and 45 years; several occupations were involved, with a clear preponderance of office workers. Women are mostly harassed for personal aspects related to emotional and relational factors; men for the content of their work. The knowledge of the phenomenon is an essential prerogative to contrast mobbing; this can be realized, at a preventive level, only through effective information and training for workers and employers, who have the legal obligation to preserve the integrity of the mental and physical status of their employees during the work.

Women and major depressive disorder: clinical perspectives on causal pathways.

2008-12-01

Epidemiological data on the prevalence of mood disorders demonstrate that major depressive disorder (MDD) is approximately twice as common in women as in men and that its first onset peaks during the reproductive years. We aimed to review key social, psychological, and biological factors that seem strongly implicated in the etiology of major depression and to focus on sex-specific aspects of depression, such as the role of a woman's reproductive life cycle in depressive symptomatology. A review of the literature, from 1965 to present, was conducted. An integrated etiological model best explains gender and sex differences in depression. Social, psychological, and biological variables must be simultaneously taken into account. These vulnerabilities include (but are not limited to) gender-specific roles in society, life stress such as trauma, a tendency toward ruminative coping strategies, and the effects of sex hormones and genetic factors. To effectively treat MDD in women and to prevent the recurrence of illness in vulnerable women, clinicians must understand the sex-specific aspects of mood disorders over the longitudinal course of women's reproductive lives. A biopsychosocial approach should, therefore, be the main focus of future research and practice, to eventually result in an integrated etiological model of depression in women. Based on the prevalence of MDD in women, timely screening, diagnosis, and intervention should be public health priorities.

To review the current status as regards transsexuality etiology and prevalence. To suggest measures to optimize care to achieve a significant improvement, including options for saving financial resources. A comparison of the contents of texts related to transsexualism in the ICD-10, DSM-IV, and guidelines of the Spanish gender units with international standards of care for transgender persons and the last draft version of the DSM-5. Systematic revision of the literature related to the etiology and prevalence of transsexualism. Significant discrepancies have been found as regards the minimum time period for diagnosis, access to hormone replacement therapy and to genital surgery, and the requirement of the so-called real-life experience. Impact of sex hormones on the etiology of transsexualism and underestimation of its prevalence was confirmed. The access to hormonal and surgical treatment requires a profound review, and decentralization of transsexual care is recommended, because all university hospitals haves psychiatrists, clinical psychologists, and endocrinologists available. Although gender reassignment surgery also requires plastic surgery specialists, plastic surgeons currently receive training in this field. Copyright © 2012 SEEN. Published by Elsevier Espana.

Household studies provide opportunities to understand influenza-like-illness (ILI) transmission, but data from (sub)tropical developing countries are scarce. To determine the viral etiology and epidemiology of ILI in households. ILI was detected by active case finding amongst a cohort of 263 northern Vietnam households between 2008 and 2013. Health workers collected nose and throat swabs for virus detection by multiplex real-time RT-PCR. ILI was detected at least once in 219 (23.7%) of 945 household members. 271 (62.3%) of 435 nose/throat swabs were positive for at least one of the 15 viruses tested. Six viruses predominated amongst positive swabs: Rhinovirus (28%), Influenza virus (17%), Coronavirus (8%), Enterovirus (5%), Respiratory syncytial virus (3%), Metapneumovirus virus (2.5%) and Parainfluenza virus 3 (1.8%). There was no clear seasonality, but 78% of episodes occurred in Winter/Spring for Influenza compared to 32% for Rhinovirus. Participants, on average, suffered 0.49 ILI, and 0.29 virus-positive ILI episodes, with no significant effects of gender, age, or household size. In contrast to US and Australian community studies, the frequency of ILI decreased as the number of household members aged below 5 years increased (p=0.006). The findings indicate the need for tailored ILI control strategies, and for better understanding of how local childcare practices and seasonality may influence transmission and the role of children.

The purpose of this study was to evaluate the etiologic and prognostic factors of open eye injuries in geriatric patients in the Southeastern region of Anatolia. Forty-five geriatric patients who underwent surgery for an open eye injury in our clinic between the years of 2008 and 2012 were evaluated retrospectively. Age, gender, cause and the mechanism of the trauma, visual acuity (VA), and the time between the trauma and the surgery were obtained from files and evaluated. The mean age of the patients was 70.4±8.2 (65-90) years. Thirty-four of the cases were male and 11 were female. The most frequent mechanism of trauma was a wood strike, while the second most common one was injury with a knife. Corneoscleral penetration was the most frequently observed trauma. The mean VA of the patients was 2.26±0.65 at admission, and was 1.53±0.99 logarithm of the minimum angle of resolution at the final evaluation. The most frequent complications of trauma were iris prolapse and hyphema. There was a significant correlation between the first and final VA. Penetrating ocular injuries are seen less frequently among geriatric patients, and their prognosis may be worse due to less-efficient wound site healing and differences in scleral rigidity. The most important factor affecting the final VA measurement was the VA of the patient at admission.

To determine the pattern of occurrence of mandibular fractures in the pediatric population in Portugal. This retrospective study reviews the records of patients 18 years of age or younger from the 10-year period 1993 to 2002. Age, gender, anatomic site, cause of the accident, weekly and monthly variation, location and type of fractures, presence and location of associated injuries, treatment methods, and complications were reviewed. During this 10-year period, 521 patients with 681 mandibular fractures were treated. Motor-vehicle accident (MVA) was the most common (53.9% patients) cause of fracture. Almost half of the patients (48.8%) were in the oldest age group (16 to 18 years old). The condyle of the mandible was involved in 31.0% of the fractures. Maxillomandibular (MMF) fixation was used in 534 (78.4%) fractures. Overall mortality in this series was 0.6% (3 patients); mortality was caused by multiple traumas, mainly head trauma. There is a need to reinforce legislation aimed to prevent MVA and the total enforcement of existing laws to reduce maxillofacial injuries among children and adolescents.

Recurrent aphthous stomatitis (RAS) affects approximately 20% of the general population. Its etiology is still unknown. To analyze this entity's clinical features. Data such as age, gender, family history of RAS, age at first episode onset, prodromal symptoms, number, size, morphology and localization of lesions, RAS clinical form, annual rate of recurrence, predisposing factors, symptoms and time for symptoms and lesions disappearance were assessed in 200 patients with RAS. Patients had RAS minor forms. Main clinical characteristics were family history of RAS (89%), first episode at ≥ 10 years of age (69%), prodromal symptoms (66%), one lesion per episode (63%), < 0.5 cm lesions (64%), rounded morphology (55%), localization at the tongue (27%), 3 recurrent episodes per year (36%), stress as predisposing factor (34%), symptom disappearance in 2 days (54%) and healing of lesions in 8 days (40%). Even when RAS is a common disorder of the oral mucosa, there is no curative treatment available. Therapeutic measures seek to reduce the pain and size of lesions, accelerate the time of recovery and decrease the rate of relapses. Copyright: © 2018 SecretarÍa de Salud.

Our prospective study aimed at exploring attention and executive functions in children with new-onset epilepsy prior to and during the early course of antiepileptic treatment. Sociodemographic and epilepsy-related factors were analyzed as potential predictors both of impaired cognitive functions as well as for changes in cognitive functioning in the early course of illness. From a total group of 115 children aged six to 17years without major disabilities, 76 children were assessed longitudinally with a screening tool for attention and executive functions (EpiTrack Junior®). Sociodemographic variables (gender, age at epilepsy onset, need of special education) and epilepsy-related variables (etiology of epilepsy, semiology of seizures, number of seizures) were considered as potential predictors for impaired functions prior to treatment and for deterioration/amelioration in cognitive functions in the early course. Attention and executive functions of children with new-onset epilepsy were significantly more often impaired when compared with a healthy population, but less often when compared with children with chronic epilepsy. The majority of children showed stable cognitive functioning in the early course of treatment. The risk of impaired cognitive functions was significantly heightened when etiology of epilepsy was unknown or not classifiable. The chance for improvement of functioning was lowered by having a genetic epilepsy, or an unknown semiology of seizures. Children with new-onset epilepsy are at high risk for impaired attention and executive functions even prior to antiepileptic treatment, especially when etiology of their epilepsy remains unclear. The high stability of cognitive functioning in the early course can be used in counseling of families who worry about negative side effects of drug treatment. Finally, a systematic assessment of cognitive functions in children with new-onset epilepsy is necessary to detect subtle deficits in the early course and adjust treatment accordingly.

2018-04-01

Pyroglutamic acid, an intermediate in glutathione metabolism, can lead to elevated anion gap metabolic acidosis as rare complication of acetaminophen therapy in adults. Acquired pyroglutamic acidosis has been observed primarily in settings associated with glutathione deficiency. Risk factors for glutathione deficiency include critical illness, chronic liver or kidney disease, advanced age, female gender, alcohol abuse, malnutrition, pregnancy, antiepileptic drugs, and chronic acetaminophen use. Diagnosis of pyroglutamic acidosis requires both the exclusion of common etiologies of increased anion gap metabolic acidosis and a high index of suspicion. Treatment involves discontinuation of acetaminophen, supportive care, and addressing risk factors for glutathione deficiency. The current report describes an ambulatory patient with multiple risk factors for glutathione deficiency, who developed recurrent pyroglutamic acidosis due to acetaminophen use with therapeutic blood levels of acetaminophen.

Purpose: This study evaluated the trends and factors associated with maxillofacial fractures treated from 1997 to 2007 in the Oral and Maxillofacial Surgery Department of the Clermont-Ferrand University Hospital. Material and Methods: This study included 364 patients of which 82% were men and 45%, 20-29-years old. The etiology, anatomical distribution, treatment modality and complications of maxillofacial fractures were examined. Results: Overall, interpersonal violence, traffic accidents and falls were the most common mechanisms of injury. There was a decreasing trend in traffic accidents and increasing one in falls as a cause of fracture over the 11-years period of this study. Young male patients were preferentially victim of interpersonal violence and traffic accidents, while middle-aged ones were of falls and work-related accidents. Middle-aged female patients were preferentially victim of traffic accidents and interpersonal violence, while older ones were of falls. And the number of fractures per patient varied according to the mechanism of injury: low after work-related accidents and high after traffic accidents. About two-third of fractures involved the mandible. Most of these mandibular fractures were treated by osteosynthesis with or without intermaxillary fixation, with the proportion of the latter increasing over time. There were very few postoperative infections and only in mandible. Conclusions: Maxillofacial fractures predominantly occur in young men, due to interpersonal violence. There is nevertheless an increasing trend in falls as a cause of fracture, especially in female patients, consistent with the increasing trend in presentation of older people. Most maxillofacial fractures involve the mandible and there is an increasing trend in treating these fractures by osteosynthesis without intermaxillary fixation. Antibiotic prophylaxis associated with dental hygiene care can be indicated to prevent postoperative infections.

Possible association between Interleukin-1beta gene and schizophrenia in a Japanese population

PubMed Central

2011-01-01

Background Several lines of evidence have implicated the pro-inflammatory cytokine interleukin-1beta (IL-1β) in the etiology of schizophrenia. Although a number of genetic association studies have been reported, very few have systematically examined gene-wide tagging polymorphisms. Methods A total of 533 patients with schizophrenia (302 males: mean age ± standard deviation 43.4 ± 13.0 years; 233 females; mean age 44.8 ± 15.3 years) and 1136 healthy controls (388 males: mean age 44.6 ± 17.3 years; 748 females; 46.3 ± 15.6 years) were recruited for this study. All subjects were biologically unrelated Japanese individuals. Five tagging polymorphisms of IL-1β gene (rs2853550, rs1143634, rs1143633, rs1143630, rs16944) were examined for association with schizophrenia. Results Significant difference in allele distribution was found between patients with schizophrenia and controls for rs1143633 (P = 0.0089). When the analysis was performed separately in each gender, significant difference between patients and controls in allele distribution of rs1143633 was observed in females (P = 0.0073). A trend towards association was also found between rs16944 and female patients with schizophrenia (P = 0.032). Conclusions The present study shows the first evidence that the IL-1β gene polymorphism rs1143633 is associated with schizophrenia susceptibility in a Japanese population. The results suggest the possibility that the influence of IL-1β gene variations on susceptibility to schizophrenia may be greater in females than in males. Findings of the present study provide further support for the role of IL-1β in the etiology of schizophrenia. PMID:21843369

Children with abuse who are admitted to the intensive care unit (ICU) may have high mortality and morbidity and commonly require critical care immediately. It is important to understand the epidemiology and clinical characteristics of these critical cases of child maltreatment.We retrospectively evaluated the data for 355 children with maltreatments admitted to the ICU between 2001 and 2015. Clinical factors were analyzed and compared between the abuse and the neglect groups, including age, gender, season of admission, identifying settings, injury severity score (ISS), etiologies, length of stay (LOS) in the ICU, clinical outcomes, and mortality. In addition, neurologic assessments were conducted with the Pediatric Cerebral Performance Category (PCPC) scale.The most common type of child maltreatments was neglect (n = 259), followed by physical abuse (n = 96). The mean age of the abuse group was less than that of the neglect group (P < .05). Infants accounted for the majority of the abuse group, and the most common etiology of abuse was injury of the central nervous system (CNS). In the neglect group, most were of the preschool age and the most common etiologies of abuse were injury of the CNS and musculoskeletal system (P < .001). The mortality rate in the ICU was 9.86%. The ISS was significantly associated with mortality in both the 2 groups (both P < .05), whereas the LOS in the ICU and injuries of the CNS, musculoskeletal system, and respiratory system were all associated with mortality in the neglect group (all P < .05). The PCPC scale showed poor prognosis in the abuse group as compared to the neglect group (P < .01).In the ICU, children in the abuse group had younger age, higher ISS, and worse neurologic outcome than those in the neglect group. The ISS was a predictor for mortality in the abuse and neglect groups but the LOS in the ICUs, injuries of the CNS, musculoskeletal system, and respiratory system were indicators for mortality in the neglect group. Most importantly, identifying the epidemiological information may provide further strategies to reduce the harm, lower the medical costs, and improve clinical care quality and outcomes in children with abuse.

Probability of detection of clinical seizures using heart rate changes.

PubMed

Osorio, Ivan; Manly, B F J

2015-08-01

Heart rate-based seizure detection is a viable complement or alternative to ECoG/EEG. This study investigates the role of various biological factors on the probability of clinical seizure detection using heart rate. Regression models were applied to 266 clinical seizures recorded from 72 subjects to investigate if factors such as age, gender, years with epilepsy, etiology, seizure site origin, seizure class, and data collection centers, among others, shape the probability of EKG-based seizure detection. Clinical seizure detection probability based on heart rate changes, is significantly (p<0.001) shaped by patients' age and gender, seizure class, and years with epilepsy. The probability of detecting clinical seizures (>0.8 in the majority of subjects) using heart rate is highest for complex partial seizures, increases with a patient's years with epilepsy, is lower for females than for males and is unrelated to the side of hemisphere origin. Clinical seizure detection probability using heart rate is multi-factorially dependent and sufficiently high (>0.8) in most cases to be clinically useful. Knowledge of the role that these factors play in shaping said probability will enhance its applicability and usefulness. Heart rate is a reliable and practical signal for extra-cerebral detection of clinical seizures originating from or spreading to central autonomic network structures.

and Objective Autoimmunity is an emerging field of research in the etiology of different neurological disorders including epilepsy. We aimed to investigate the presence of neuronal autoantibodies in focal epilepsy with unknown cause and their clinical correlates in both drug-responsive and resistant patients. Between 2009 and 2010 94 patients were prospectively enrolled, had their antibodies tested and clinically followed." An additional 50 age- and gender-matched controls were also tested for antibodies. Age at examination, gender, age at onset, seizure frequency, risk factors, seizure precipitants, and type of seizures were noted. Plasma obtained from patients was frozen at -80°C and analysed for autoantibodies against VGKC-complex, VGCC, GAD, LGI1, CASPR2, NMDA, AMPA and GABAB receptors with immunocytochemistry and radioimmunoassay as required. Thirteen (13.8%) patients, but none of the controls, had antibodies (p=0.003). Antibodies were directed against the uncharacterized components of VGKC-complex in 5 patients (5.3%), GAD in 4 patients (4.2%), NMDA-R in 1 patient (1%), AMPA-R in 1 patient (1%) and both GAD and VGKC-complex in 2 patients (2.1%). Prognosis of epilepsy, in subsequent follow-up, did not correlate to general presence of anti-neuronal antibodies with slightly more patients with antibodies epilepsy control than without (76.9% vs. 69.1%, not-statistically significant. Three patients with suspected active autoimmunity and epilepsy who were treated, showed a response to treatment with a reduction in the seizure frequency. Although most clinical features were identical between seropositive and seronegative patient groups, seropositive patients were more likely to have inflammatory/autoimmune disorders in their medical history. In keeping with previous studies, we have shown anti-neuronal antibodies in a proportion of focal epilepsy patients. Although autoimmunity might merely occur as a bystander effect in many chronic neurological disorders, association of anti-neuronal antibodies with good response to immunotherapy and coexisting autoimmune disorders suggests that anti-neuronal autoimmunity might participate in seizure formation at least in a subgroup of focal epilepsy patients. Immunity may play a role in some patients with unknown etiology regardless of prognosis and immunmodulatuar treatment may be helpful in seropositive group. Copyright © 2017 Elsevier B.V.

Primary intracerebral hemorrhage (ICH) studies often use hematoma location rather than ICH etiologies when assessing outcome. Characterizing ICH using hematoma location is effective/reproducible, but may miss heterogeneity among these ICH locations, particularly lobar ICH where competing primary ICH etiologies are possible. We subsequently investigated baseline characteristics/outcome differences of spontaneous, primary ICH by their etiologies: cerebral amyloid angiopathy (CAA) and hypertension. Primary ICH clinical/outcomes data were prospectively collected between 2009 and 2015. Modified Boston criteria were used to identify "probable/definite" and "possible" CAA-ICH, which were evaluated separately. SMASH-U criteria were used to identify hypertension ICH. Medication and systemic disease coagulopathy ICH were excluded. Baseline characteristics/outcomes among "probable/definite" CAA-ICH, "possible" CAA-ICH, and hypertension ICH were compared using logistic regression. Mortality models using ICH etiologies compared to hematoma location as predictor variables were assessed. Two hundred and four hypertension ICHs, 55 "probable/definite" CAA-ICHs, and 46 "possible" CAA-ICHs were identified. Despite older age and larger ICH volumes, lower hospital mortality was seen in "probable/definite" CAA-ICH versus hypertension ICH (OR 0.2; 95% CI 0.05-0.8; p = 0.02) after adjusting for female gender, components of ICH score, and EVD placement. There were no mortality differences between "possible" CAA-ICH and hypertension ICH. However, lower hospital mortality was seen in "probable/definite" versus "possible" CAA-ICH (OR 0.2; 95% CI 0.04-0.7; p = 0.02). When using ICH etiology rather than hematoma location, hospital mortality models significantly improved (χ 2 : [df = 2, N = 305] = 6.2; p = 0.01). Further investigation is required to confirm the mortality heterogeneity seen within our primary ICH cohort. Hematoma location may play a role for these findings, but the mortality differences seen among lobar ICH using CAA-ICH subtypes and a failure to identify mortality differences between "possible" CAA-ICH and hypertension ICH suggest the limitations of accounting for hematoma location alone.

Hypopituitarism in adult life is commonly acquired and the main causes are known as pituitary tumors and/or their treatments. Since there are new insights into the etiology of hypopituitarism and presence of differences in various populations, more studies regarding causes of hypopituitarism are needed to be done in different ethnic groups with sufficient number of patients. Therefore, we performed a multi-center database study in Turkish population investigating the etiology of hypopituitarism in 773 patients in tertiary care institutions. The study was designed and coordinated by the Pituitary Study Group of SEMT (The Society of Endocrinology and Metabolism of Turkey). Nineteen tertiary reference centers (14 university hospitals and 5 training hospitals) from the different regions of Turkey participated in the study. It is a cross-sectional database study, and the data were recorded for 18 months. We mainly classified the causes of hypopituitarism as pituitary tumors (due to direct effects of the pituitary tumors and/or their treatments), extra-pituitary tumors and non-tumoral causes. Mean age of 773 patients (49.8 % male, 50.2 % female) was 43.9 ± 16.1 years (range 16-84 years). The most common etiology of pituitary dysfunction was due to non-tumoral causes (49.2 %) among all patients. However, when we analyze the causes according to gender, the most common etiology in males was pituitary tumors, but the most common etiology in females was non-tumoral causes. According to the subgroup analysis of the causes of hypopituitarism in all patients, the most common four causes of hypopituitarism which have frequencies over 10 % were as follows: non-secretory pituitary adenomas, Sheehan's syndrome, lactotroph adenomas and idiopathic. With regard to the type of hormonal deficiencies; FSH/LH deficiency was the most common hormonal deficit (84.9 % of the patients). In 33.8 % of the patients, 4 anterior pituitary hormone deficiencies (FSH/LH, ACTH, TSH, and GH) were present. Among all patients, the most frequent cause of hypopituitarism was non-secretory pituitary adenomas. However, in female patients, present study clearly demonstrates that Sheehan's syndrome is still one of the most important causes of hypopituitarism in Turkish population. Further, population-based prospective studies need to be done to understand the prevalence and incidence of the causes of hypopituitarism in different countries.

The aim of the study was to identify the epidemiology of chronic kidney disease of uncertain etiology in Sri Lanka. A cross-sectional study was carried out by analyzing health statistics, and three cohort studies were conducted (n = 15 630, 3996, and 2809) to analyze the demographic information, age-specific prevalence, etiology, and stage of presentation. We screened 7604 individuals for chronic kidney disease of uncertain etiology. The results showed that the male:female ratio was 2.4:1, the mean age of patients was 54.7 ± 8 years, 92% of the patients were farmers, and 93% consumed water from shallow dug wells. Familial occurrence was common (36%). The prevalence of chronic kidney disease in different age groups was 3% in those aged 30-40 years; 7% in those aged 41-50 years, 20% in those aged 51-60 years, and 29% in those older than 60 years. Chronic kidney disease of uncertain etiology was diagnosed in 70.2% of patients, while 15.7% and 9.6% were due to hypertension and diabetic mellitus, respectively. The majority of patients were stage 4 (40%) at first presentation, while 31.8% were stage 3 and 24.5% were stage 5. Stage 1 and 2 presentation accounted for only 3.4%. Low prevalence of CKDU was noticed (1.5%) among those who consumed water from natural springs. Prevalence was highest among males, rice farming communities, and those presenting at later disease stages.

The etiology of schizophrenia continues to be confounding and elusive. Some knowledge gaps exist in the neurodegenerative theory of schizophrenia. Oxidative DNA damage and repair deficits are relevant to the mechanisms of neurodegeneration but have not been studied in drug naïve schizophrenia. The present study used the comet assay technique to study the extent of DNA damage in circulating peripheral lymphocytes of patients with drug naïve schizophrenia (n = 40) along with an age and gender matched control group (n = 40). We also assessed the DNA repair efficiency in cases following incubation in a nutrient medium. All the assayed comet parameters demonstrated significantly greater baseline DNA damage in cases in comparison to the controls except for head diameter (p < 0.001 for all significant results, p = 0.32 for head diameter). Gender, age and duration of illness (p = 0.21, 0.69 and 0.12 respectively for tail length) did not influence any of the parameters significantly. Significant decrease was noted in the comet tail length and percentage of DNA in comet tail (p < 0.001 for both) in cases following incubation suggesting that the DNA repair machinery was preserved. No difference in DNA repair efficiency was noted between the genders (p = 0.23 for tail length). Our findings confirm the presence of significant baseline DNA damage in schizophrenia even prior to the initiation of anti-psychotic treatment. Additionally, intact genomic repair efficiency was noted in this group as a whole. These results provide some evidence for oxidative DNA damage as molecular link underpinning neurodegeneration in drug naïve schizophrenia. Copyright © 2015 Elsevier Ltd. All rights reserved.

Background Absence epilepsy (AE) is etiologically heterogeneous and has at times been associated with idiopathic dystonia. Objectives Based on the clinical observation that children with AE often exhibit, interictally, a disorder resembling writer’s cramp but fully definable as dysgraphia, we tested the hypothesis that in this particular population dysgraphia would represent a subtle expression of dystonia. Methods We ascertained the prevalence of dysgraphia in 82 children with AE (mean age 9.7) and average intelligence and compared them with 89 age-, gender- and class-matched healthy children (mean age 10.57) using tests for handwriting fluency and quality, based on which we divided patients and controls into four subgroups: AE/dysgraphia, AE without dysgraphia, controls with dysgraphia and healthy controls. We compared the blink reflex recovery cycle in children belonging to all four subgroups. Results We identified dysgraphia in 17/82 children with AE and in 7/89 controls (20.7 vs 7.8%; P = 0.016) with the former having a 3.4-times higher risk of dysgraphia regardless of age and gender (odd ratio: 3.49; 95% CI 1.2, 8.8%). The AE/dysgraphia subgroup performed worse than controls with dysgraphia in one test of handwriting fluency (P = 0.037) and in most trials testing handwriting quality (P< 0.02). In children with AE/dysgraphia the blink reflex showed no suppression at short interstimulus intervals, with a difference for each value emerging when comparing the study group with the three remaining subgroups (P<0.001). Conclusions In children with AE, dysgraphia is highly prevalent and has a homogeneous, distinctive pathophysiological substrate consistent with idiopathic dystonia. PMID:26132164

Many of the patients with lymph node tuberculosis show 'Paradoxical Response" in the form of appearance of new lymph node (LN) or increase in the size of existing LN, development of new disease in other organ and worsening of the disease while on treatment. Reason behind such response in only selective patients is not clearly understood. We evaluated the pattern and predictors for paradoxical response(s) (PR) in patients with peripheral lymph node tuberculosis (TB). Study included patients aged > 6 years with peripheral lymphadenopathy of tubercular etiology attending a tertiary care hospital from Jan 2010 to Dec 2010. PR in our study was defined as worsening of pre-existing disease or development of new lesions in a patient who has been on anti-TB therapy for at least 2 weeks. One hundred ten patients with peripheral lymph node TB were included. Their mean age was 27.5 ± 5 years and 68 (62%) were females. PR occurred in 28 (25%) patients, at a mean onset time of 6 weeks (range 2-12 weeks) after starting anti-TB medication. Four of these 28 patients experienced PR on two occasions. Of these, 22 (79%) patients presented with enlarged lymph nodes only, 8 (29%) with new nodes at same or different site and 2 (7%) with discharging sinus. PR was observed more in younger age group (p> 0.05), female gender (p> 0.05), unilateral lymphadenopathy (p> 0.05) and those with positive AFB on initial examination (p< 0.01). Paradoxical response in peripheral lymph node TB is associated with younger age, female gender, unilateral lymphadenopathy and those with positive AFB on initial examination.

Posaconazole (PCZ) is given at 200 mg three times daily as a fungal prophylaxis in neutropenic hematologic malignancy patients. A relationship between exposure, plasma concentration, and efficacy is suggested. The objectives of this prospective study were to analyze the PCZ plasma concentration in hematology adults at high risk of developing invasive fungal infections (IFIs), and factors that could have an impact on the PCZ plasma concentration. PCZ plasma concentrations were measured after 2, 7, 10, 14, and 21 days of PCZ prophylaxis. Factors such as gender, age, body weight, posology, treatment duration, mucositis, proton pump inhibitor (PPI) use, and food intake were studied. Sixty-three patients were included, with a median age of 52 years (range 17-70) and a median weight of 75 kg (range 47-150). The median PCZ plasma concentration of the 63 patients ranged from 0.42 to 0.48 mg/L. At day 2, 30% of PCZ plasma concentration were under 0.35 mg/L, and at day 7, 74% were <0.70 mg/L. PCZ plasma concentrations were not affected by gender, age, body weight, or treatment duration. We found that food intake had a high influence on PCZ plasma concentrations (p = 0.0049). PCZ was well tolerated. One patient has developed a probable IFI, probably related to a low exposure to PCZ. PCZ therapeutic drug monitoring (TDM) is essential in order to early detect patients with low concentrations, to assess the etiology of such results, and to decide on the treatment strategy to apply.

To analyze the association of stroke etiological subtypes with severity and outcomes at 3 and 12 months in patients ≤50 years. Observational study of patients admitted to a stroke unit (2007-2013). demographic data, vascular risk factors, comorbidities, severity on admission (NIHSS), and good functional outcome (mRS ≤ 1) at 3 and 12 months. We used multivariate analyses to evaluate the influence of stroke etiology on severity and outcomes. We included 214 patients, 58.3 % men, mean age 41.4 years. General linear models showed all etiologies were more severe than lacunar strokes (P < 0.05). Atherothrombotic strokes showed greater severity than those of undetermined and uncommon etiology, whereas cardioembolic strokes were more severe than cryptogenic. Taking into account specific etiologies, atherothrombotic strokes (B = 5.860; 95 % CI 2.979-8.751), cervical artery dissection (CAD) [B = 7.485; 95 % confidence interval (CI) 4.734-10.237], and atrial fibrillation (AF) strokes (B = 5.773; 95 % CI 2.704-8.132) were more severe than other etiologies. Logistic regression models showed that strokes of uncommon etiology, especially those not related to CAD, had a lower probability of good outcome at 3 months [odds ratio (OR) = 0.197; CI 95 % 0.044-0.873], whereas atherothrombotic strokes were associated with this probability at 12 months (OR = 0.187; 95 % CI 0.037-0.951; P = 0.007). In patients ≤50 years of age, strokes of atherothrombotic, cardioembolic (particularly those due to AF), and uncommon etiology had a greater severity than the rest. Furthermore, strokes of uncommon etiology, especially those different from CAD, decreased the probability of a good outcome at 3 months, as did atherothrombotic strokes at 1 year.

To identify predictors of outcome, epilepsy, spasticity and depression one year after severe acquired brain injury. Retrospective cohort study. A consecutive sample of 165 patients with severe acquired brain injury admitted for inpatient rehabilitation during a 18-month time period, was contacted and offered home visits one-year after brain injury. Of the 165 patients 12 did not participate. The cohort included patients with different etiologies primarily traumatic brain injury (65), stroke (25) and subarachnoid hemorrhage (34). Functional independent measure (FIM) was measured at admission at rehabilitation unit and at follow-up. At follow-up the presence of epilepsy, spasticity, and depression was evaluated. Using multiple logistic regression a short length of stay at acute hospital (LOS1) (P=0.004), a high FIM score at admission (P<0.001), and low age (P=0.003), were all predictors of good outcome. No difference was found between etiologies (P=0.077). The presence of spasticity was predicted by low FIM score (P< 0.001), longer LOS1 (P< 0.036), etiology (P< 0.001), and lower age (P=0.001). Depression was predicted by higher age (P=0.035). Age, functional status, and length of acute hospital stay are associated with outcome one year after brain injury. The functional outcome was not correlated to etiology.

The goal of this study was to identify the etiology of events and demographics of patients that experience complications requiring activation of the Rapid Response Team (RRT) during the first 24 h following anesthetic care. We performed a retrospective review of the Quality Improvement database from the Department of Anesthesiology & Pain Medicine at Nationwide Children's Hospital. The database was searched to identify those patients who had a RRT evaluation activated within 24 h of receiving anesthesia or procedural sedation. These patients' charts were reviewed to obtain demographic information, etiology of the RRT call, and outcomes. The study cohort included 106 RRT calls that were made over a 3-year period. Six patients were excluded from analysis due to incomplete datasets. One hundred patients remained for analysis including 60 males and 40 females. Patients ranged in age from 0.08 to 31.21 years (7.8 ± 7.7 years, median 5.3 years). Seventy-one patients were American Society of Anesthesiologists' (ASA) status 3 or 4 and 29 patients were ASA status 1 or 2. Five calls were made for patients who had undergone procedural sedation while the other 95 were on patients who received general anesthesia. The average time to the RRT call after the end of anesthetic care was 11.4 ± 6.6 h. Respiratory concern was the most common reason for RRT initiation, accounting for 71 of the 100 calls. Forty-nine patients had a recent respiratory illness, chronic respiratory-related disease, or history of preterm birth. Fifty patients (50%) were transferred to a higher level of care following the RRT consult. There was no significant difference between age, gender, ASA status, or etiology of the event for patients transferred vs. those who were not. A significant difference was noted in the Pediatric Early Warning Score of patients transferred to a higher level of care in comparison to patients who remained on the floor (4 ± 2 vs. 3 ± 2, P = 0.0097). RRT calls were most common for respiratory concerns. High ASA status, general anesthesia administration, and the presence of acute or chronic conditions prior to anesthetic administration predispose a patient to perioperative complications resulting in the need for an RRT call. © 2016 John Wiley & Sons Ltd.

Venous ulcers account for 70% of chronic leg ulcers and affect about 2-7% of the population, causing much socioeconomic impact and reducing patients' quality of life. In this study we aimed to describe the clinical features of venous ulcers and sociodemographic characteristics of patients with ulcers due to chronic venous disease (CVD). This cross-sectional, observational study was conducted at the Vascular Surgery Service, Universidade Federal de Sergipe, in northeastern Brazil. The study included a consecutive series of 154 patients with active venous ulcers (CEAP C6) in the lower limb due to CVD. Sociodemographic characteristics (age, gender, race, monthly income, education, occupation, and caregiver) and clinical data (affected limb, ulcer site, etiopathogenesis, recurrence, and time elapsed since the first episode of ulcer) were collected. A possible correlation of time elapsed since the first episode of ulcer and number of recurrences with primary or secondary etiology was analyzed by Mann-Whitney U-test. Of the 154 patients analyzed, 79% were female, 94% were ethnically black or brown, 90% had a monthly income less than or equal to minimum wage, 47% were illiterate, 35% had not completed elementary school, 50% had informal jobs, 19.5% were retired, and 18.2% received sick pay from the social security system. The mean age was 53.7 years. Both limbs were affected similarly, and venous ulcers were located predominantly on the medial aspect of the leg (84%). The median time elapsed since the first episode of ulcer was 36 months, being significantly higher in patients with venous ulcers of secondary etiology (P < 0.0003). The prevalence of recurrence was also significantly higher in patients with venous ulcers of secondary etiology (P < 0.001). According to CEAP classification, 65% of ulcers were primary (Ep), 94.1% demonstrated reflux involving the superficial system (As), 92% had incompetent perforators (Ap), 35% demonstrated reflux involving the deep system (Ad), and all ulcers showed reflux without obstruction (Pr). Venous ulcers were more prevalent among low-income patients, especially chronic, recurrent ulcers of primary etiology. This finding highlights the need for improvements in patient care and surgical treatment in most cases aimed at ulcer healing and reduced recurrence. Better care would improve patients' quality of life and reduce social security expenditures. Crown Copyright © 2013. Published by Elsevier Inc. All rights reserved.

Osteosarcoma Overview.

2017-06-01

Osteosarcoma (OS) is the most common primary malignancy of bone and patients with metastatic disease or recurrences continue to have very poor outcomes. Unfortunately, little prognostic improvement has been generated from the last 20 years of research and a new perspective is warranted. OS is extremely heterogeneous in both its origins and manifestations. Although multiple associations have been made between the development of osteosarcoma and race, gender, age, various genomic alterations, and exposure situations among others, the etiology remains unclear and controversial. Noninvasive diagnostic methods include serum markers like alkaline phosphatase and a growing variety of imaging techniques including X-ray, computed tomography, magnetic resonance imaging, and positron emission as well as combinations thereof. Still, biopsy and microscopic examination are required to confirm the diagnosis and carry additional prognostic implications such as subtype classification and histological response to neoadjuvant chemotherapy. The current standard of care combines surgical and chemotherapeutic techniques, with a multitude of experimental biologics and small molecules currently in development and some in clinical trial phases. In this review, in addition to summarizing the current understanding of OS etiology, diagnostic methods, and the current standard of care, our group describes various experimental therapeutics and provides evidence to encourage a potential paradigm shift toward the introduction of immunomodulation, which may offer a more comprehensive approach to battling cancer pleomorphism.

Gender Dysphoria and Co-Occurring Autism Spectrum Disorders: Review, Case Examples, and Treatment Considerations.

2014-12-01

Transgender and gender nonconforming people who fulfill diagnostic criteria for autism spectrum disorders (ASDs) often present to mental health providers with concerns that are distinct from those without ASDs. Gender Dysphoria (GD) and ASDs have been proposed to share etiologic mechanisms and there is evidence that ASDs may be more common in transgender and gender nonconforming people. We explore the impact of ASD characteristics on individual gender identity, expression, and the process of psychotherapy. The authors present two case studies of high-functioning individuals with ASD and GD diagnoses. The limited ability to articulate an inner experience, deficits in Theory of Mind (ToM), along with the intolerance of ambiguity as a manifestation of the cognitive rigidity characteristic of ASDs, may present special difficulties to gender identity formation and consolidation and create challenges in psychotherapy. The authors suggest that ASDs do not preclude gender transition and that individuals with high-functioning ASDs are capable of making informed decisions regarding their medical care and life choices. The authors also consider possible challenges and suggest techniques for assisting such clients in exploring their gender identities.

Hematoma of the ligamentum flavum (LF) is a rare cause of neural compression and sciatica. Currently, the etiology and epidemiological characteristics of ligamentum flavum hematoma (LFH) are unknown and epidemiological investigations using rewieving of reported cases have not been performed. We report the case of a 63-year-old man with a LFH compressing the spinal canal at the left L2–L3 level, rewieved relevant literature. In Medline research, wefound a total of 50 reported cases with LFHs, and the interesting point of these cases were analyzed. Many of cases were old males. Interestingly, 39 of the 50 cases were reported from Asian countries. The ages of 42 patients could be verified. The youngest age was 45 years, oldest age was 81 years, and mean age was 66.07 years. Thirty-three out of these 42 patients (78.53%) were older than 60 years. An important aspect of the present review is to bring attention for occurrence in older Asian males. With an increasing number of elderly people in the general population, there is a need to investigate risk factors such as sexual gender, age, and geographic location for LFH. PMID:27041879

The homeostasis of essential trace elements such as selenium and manganese may be altered in patients with severe diseases of various etiologies (trauma brain injuries, tumors, leukemias, lymphomas, neurological diseases). Concentration of manganese and selenium were determined in cerebrospinal fluid by electrothermal atomic absorption spectrometry in 50 hospitalized children with various clinical ethiologies including oncological, neurological, and brain related diseases. The concentrations of manganese in cerebrospinal fluid of children were 0.97±0.67 μg/L. The concentrations of selenium were 13.3±3.5 μg/L. The concentrations were similar as published in adults. The values did not correlated with the age, gender and severity of the disease. We evaluated values of selenium and manganese in cerebrospinal fluid of seriously diseased children. © 2017 Wiley Periodicals, Inc.

Sorafenib is an oral angiogenetic multikinase inhibitor approved in the treatment of renal and hepatocellular carcinoma. Bleeding and venous thrombotic events have been described with angiogenetic agents but cerebrovascular accidents are rarely reported. We report two cases of patients with hepatocellular carcinoma who developed a cerebrovascular accident while on sorafenib. Neither patient had any risk factors for the cerebrovascular events apart from gender and age in the second patient. Laboratory data were noncontributory. The head CT scan did not reveal acute abnormalities. No hemodynamically significant stenosis was visible in the carotid ultrasound, and the echocardiogram showed normal size of the heart chambers and normal systolic function of the left ventricle. Sorafenib was discontinued in both cases. Physicians should monitor patients receiving sorafenib for neurologic symptoms, and in the absence of other etiology, prompt discontinuation of this drug should be considered. PMID:21687621

Cancer.gov

Using the guidelines for cancer biomarker validation suggested by Pepe et al. (23), we propose to perform a Phase 2 study of DCP for the detection of early stage HCC. In this proposal, we plan to perform a larger case-control study to compare the sensitivity and specificity of DCP and AFP alone and in combination in differentiating patients with all stages of HCC and more importantly those with early HCC from patients with cirrhosis. We plan to enroll consecutive patients with HCC seen at 7 centers in the United States. Controls are frequency matched to cases (all center combined) using the following criteria: age (±10 years), gender (+10%) and etiology of liver disease (viral vs non-viral (+5%). Within each participating institution, there will be an equal number (+20%) of cases and controls.

Background The aim of the study was to identify the epidemiology of chronic kidney disease of uncertain etiology in Sri Lanka. Methods A cross-sectional study was carried out by analyzing health statistics, and three cohort studies were conducted (n = 15 630, 3996, and 2809) to analyze the demographic information, age-specific prevalence, etiology, and stage of presentation. We screened 7604 individuals for chronic kidney disease of uncertain etiology. Results The results showed that the male:female ratio was 2.4:1, the mean age of patients was 54.7 ± 8 years, 92% of the patients were farmers, and 93% consumed water from shallow dug wells. Familial occurrence was common (36%). The prevalence of chronic kidney disease in different age groups was 3% in those aged 30–40 years; 7% in those aged 41–50 years, 20% in those aged 51–60 years, and 29% in those older than 60 years. Chronic kidney disease of uncertain etiology was diagnosed in 70.2% of patients, while 15.7% and 9.6% were due to hypertension and diabetic mellitus, respectively. The majority of patients were stage 4 (40%) at first presentation, while 31.8% were stage 3 and 24.5% were stage 5. Stage 1 and 2 presentation accounted for only 3.4%. Conclusions Low prevalence of CKDU was noticed (1.5%) among those who consumed water from natural springs. Prevalence was highest among males, rice farming communities, and those presenting at later disease stages. PMID:25787679

Patient Disease Perceptions and Coping Strategies for Arthritis in a Developing Nation: A Qualitative Study

2011-01-01

Background There is little prior research on the burden of arthritis in the developing world. We sought to document how patients with advanced arthritis living in the Dominican Republic are affected by and cope with their disease. Methods We conducted semi-structured, one-to-one interviews with economically disadvantaged Dominican patients with advanced knee and/or hip arthritis in the Dominican Republic. The interviews, conducted in Spanish, followed a moderator's guide that included topics such as the patients' understanding of disease etiology, their support networks, and their coping mechanisms. The interviews were audiotaped, transcribed verbatim in Spanish, and systematically analyzed using content analysis. We assessed agreement in coding between two investigators. Results 18 patients were interviewed (mean age 60 years, median age 62 years, 72% women, 100% response rate). Patients invoked religious and environmental theories of disease etiology, stating that their illness had been caused by God's will or through contact with water. While all patients experienced pain and functional limitation, the social effects of arthritis were gender-specific: women noted interference with homemaking and churchgoing activities, while men experienced disruption with occupational roles. The coping strategies used by patients appeared to reflect their beliefs about disease causation and included prayer and avoidance of water. Conclusions Patients' explanatory models of arthritis influenced the psychosocial effects of the disease and coping mechanisms used. Given the increasing reach of global health programs, understanding these culturally influenced perceptions of disease will be crucial in successfully treating chronic diseases in the developing world.

Background: Tobacco smoking has been recognized as the most important risk factor for chronic obstructive pulmonary disease (COPD) for a long time, but recent studies have shown that nonsmokers also contribute to a significant proportion of COPD. This study was performed to find out the proportion of nonsmoker individuals among COPD patients and to determine various etiologies in nonsmoker COPD patients. Materials and Methods: This study was an observational cross-sectional study conducted in Department of Pulmonary Medicine, MLN Medical College, Allahabad. A total of 200 COPD patients, aged >18 years of either gender with COPD, diagnosed by clinical and spirometric criteria (GOLD guideline) were included in the study. Results: Of the 200 COPD patients, the proportion of nonsmoker patients was 56.5%, and the smoker was 43.5%. Among 113 nonsmoker COPD patients, maximum number of patients (69.03%) belonged to low socioeconomic status but most important and statistically significant risk factor was exposure to biomass smoke (53.98%), other significant risk factors were treated pulmonary tuberculosis (32.74%), and long-standing asthma (14.16%). Risk factors that were not statistically significant were occupational exposure (9.73%), exposure to outdoor air pollution (3.54%), and lower respiratory tract infection during childhood (1.77%). The patients who were exposed to more than one risk factors, developed COPD at an earlier age. Conclusions: This study revealed that nonsmokers contribute a significant proportion of COPD patients. Multiple risk factors other than smoking also play a major role in the development of COPD, particularly exposure to biomass smoke, treated pulmonary tuberculosis, and long-standing asthma.

Socioeconomic status (SES) discrepancies exist for child and adult cancer morbidity and are a major public health concern. In this Swiss population-based matched case–control study on the etiology of childhood leukemia, we selected the cases from the Swiss Childhood Cancer Registry diagnosed since 1991 and the controls randomly from census. We assigned eight controls per case from the 1990 and 2000 census and matched them by the year of birth and gender. SES information for both cases and controls was obtained from census records by probabilistic record linkage. We investigated the association of SES with childhood leukemia in Switzerland, and explored whether it varied with different definitions of socioeconomic status (parental education, living condition, area-based SES), time period, and age. In conditional logistic regression analyses of 565 leukemia cases and 4433 controls, we found no consistent evidence for an association between SES and childhood leukemia. The odds ratio comparing the highest with the lowest SES category ranged from 0.95 (95% CI: 0.71–1.26; Ptrend = 0.73) for paternal education to 1.37 (1.00–1.89; Ptrend = 0.064) for maternal education. No effect modification was found for time period and age at diagnosis. Based on this population-based study, which avoided participation and reporting bias, we assume the potential association of socioeconomic status and childhood leukemia if existing to be small. This study did not find evidence that socioeconomic status, of Switzerland or comparable countries, is a relevant risk factor or strong confounder in etiological investigations on childhood leukemia.

Urinary tract infection (UTI) represents one of the most common diseases encountered in community medical practice. In resource poor settings, treatment is usually empiric due to the high cost and long duration required for reporting diagnosis by culture and antibiotic susceptibility testing. With the growing problem of drug resistance knowledge of antibiotic susceptibility pattern is pertinent for successful eradication of invading pathogens. Our study, the first of its kind in Cameroon, analyzed the distribution and antibiotic susceptibility of bacteria causing community-acquired urinary tract infection (CAUTI) in two towns (Bamenda and Buea) with a large number of young and middle aged persons, to provide data that could guide empiric treatment. We cultured 235 urine specimens and analyzed the antibiotic susceptibility of isolates by the disc diffusion technique. Uropathogens were recovered from 137 (58.3%), with prevalence rates in Buea and Bamenda being 65.9% and 54% respectively. Predominant pathogens were Escherichia coli (31.4%), Klebsiella oxytoca (25.5%) and Staphylococcus spp (24.1%). Geographic variation in uropathogen distribution and antibiotic susceptibility was observed, and a significant difference in pathogen distribution with respect to gender. The 20-39 years age group had the highest prevalence of infection. All pathogens isolated were detected in this group. Isolates exhibited low susceptibility to antibiotics tested. Bamenda isolates generally exhibited lower susceptibility compared to those from Buea. Regional variation in etiology of CAUTI and antibiotic susceptibility observed in our study emphasizes the need to establish local and national antimicrobial resistance monitoring systems in Cameroon to provide information for the development of CAUTI treatment guidelines.

Background Bacterial meningitis in older adults is a well-studied and serious disease, but few studies have investigated the epidemiology and outcomes of community-acquired meningitis in older adults. Methods We conducted a retrospective study of 619 adults in Houston, Texas, with community-acquired meningitis hospitalized between January 1, 2005, and January 1, 2010. Patients were categorized as older if age ≥65 (N=54) and younger if age 18–64 (N=565). An adverse clinical outcome was defined as a Glasgow Outcome Scale score of 4 or less. Results Older patients consisted of 8.7% (54/619) of the total cohort and had higher rates of comorbidities, abnormal neurological and laboratory findings, abnormalities on computed tomography and magnetic resonance imaging of the head and adverse clinical outcomes (ACO) (p<0.05). The majority of patients (65.8%) had meningitis of unknown etiology. Bacterial meningitis was an infrequent cause (7.4%). Of the known causes, bacterial meningitis and West Nile virus were more common in older patients. In contrast, younger patients more frequently had cryptococcal and viral meningitis. On logistic regression, female gender was predictive of a poor outcome in the older patients, whereas abnormal neurologic exam, fever, and CSF glucose <45mg/dLwere significant poor prognostic factors in younger patients (p<0.05). Conclusion Most cases of community-acquired meningitis are of unknown origin. Older patients are more likely to have bacterial meningitis and West Nile virus infection when a cause can be identified. They also have more neurologic abnormalities, laboratory and imaging abnormalities, as well as adverse clinical outcomes. PMID:25370434

Early-infantile epileptic encephalopathy (EIEE) with suppression-bursts is a severe neonatal epileptic encephalopathy. The etiology is multiple, with cerebral malformations as the more frequent. We review the clinical and video/EEG aspects of eight infants with EIEE. These infants, aged between 4 and 70 days at the time of video/EEG recordings, were studied in relation to their clinical and video/EEG characteristics, evolution, persistence of suppression-burst pattern and etiology. Seven of the eight infants showed an ictal clinical sign correlated to the burst of the suppression-burst pattern, four of whom died within 11 months of age. The other three are alive. One, now aged 4 years, underwent surgery for hemimegalencephaly and is seizure-free, with good neurological outcome. One, now aged 9 months, was pyridoxine-dependent and she is seizure-free, and with normal neurological evolution under pyridoxine therapy. One, now aged 3 years and 9 months, is seizure-free, but with severe neurological and cognitive impairment. The only child who did not show a clinical ictal correlation of burst is also alive, now aged 3 years and 9 months, with drug-resistant epilepsy, and severe neurological and cognitive deficits. With regard to the etiology, three showed structural abnormalities, two more showed some signs of prenatal origin of neurological disease, and three had metabolic etiology. Our study confirms that EIEE is a severe age-dependent early epileptic encephalopathy. The etiology is mostly malformative. The prognosis is poor regarding motor and cognitive development, seizures, as well as life expectancies. The presence of an ictal burst of the suppression-burst pattern usually correlates with a negative outcome.

A genetically informed longitudinal cross-lagged model was applied to twin data to explore etiological links between difficult temperament and negative parenting in early childhood. The sample comprised 313 monozygotic (MZ) and dizygotic (DZ) twin pairs. Difficult temperament and negative parenting were assessed at ages 2 and 3 using parent ratings. Both constructs were interrelated within and across age (rs .34–.47) and showed substantial stability (rs .65–.68). Difficult temperament and negative parenting were influenced by genetic and environmental factors at ages 2 and 3. The genetic and nonshared environmental correlations (rs .21–.76) at both ages suggest overlap at the level of etiology between the phenotypes. Significant bidirectional associations between difficult temperament and negative parenting were found. The cross-lagged association from difficult temperament at age 2 to negative parenting at age 3 and from negative parenting at age 2 and difficult temperament at age 3 were due to genetic, shared environmental, and nonshared environmental factors. Substantial novel genetic and nonshared environmental influences emerged at age 3 and suggest change in the etiology of these constructs over time. PMID:26490166

Although sporadic male predominance in hiccup patients has been reported, the association between gender differences and triggering factors has rarely been evaluated in patients with hiccups. The aim of this study was to investigate whether gender differences exist in hiccup patients by analyzing all previously published hiccup literature containing gender and etiology information. Published literature on this topic was identified using a standardized search strategy in the PubMed, SCOPUS, and CINAHL electronic databases. The literature search included studies published from January 1990 to December 2013. Searches were limited to English-language publications. Of 476 identified studies, 318 studies were eligible including eight case-control studies that contained nonhiccup control groups. Triggering factors for hiccups were categorized into two types: central nervous system (CNS) and non-CNS causes. Odds ratios (ORs) were calculated for the eight case-control studies and event rates for the other studies by meta-analysis. In addition, gender differences and mean ages were analyzed for the case studies. Pooled OR was 2.42 (95% confidence interval [CI] 1.40-4.17) with inclination for male predominance. Subgroup analysis by cause showed clear male predominance in the non-CNS type with OR of 11.72 (95% CI 3.16-43.50), whereas indistinct in the CNS type with OR of 1.74 (95% CI 0.95-3.16). Of the remaining 310 studies with 864 patients, previous findings were consistent. Male predominance was consistent in non-CNS (85.1%, 95% CI 78.2-90.2) and unknown origin (82.2%, 95% CI 75.8-87.2) patients, whereas mitigating the sex discrepancy in those with CNS origin (65.8%, 95% CI 53.1-76.5). We demonstrated male predominance in hiccup patients. This gender difference for hiccups was more pronounced in patients with non-CNS causes, whereas indistinct in patients with CNS causes.

Although the lung is not traditionally thought of as an organ affected by sex-based differences, emerging literature elucidates major differences between men and women in the development, physiology, and predilection to and outcomes in lung diseases. These differences are driven by both differences in sex hormones and differences in environmental exposures. However, in many cases the underlying etiology of these sex- and gender-based differences is unknown. This article outlines the state-of-the-art knowledge on the etiology of sex differences in lung disease, including differences in lung development and physiology, and reviews therapy recommendations that are sex based.

Our aim was to validate recent epidemiologic trends and describe the distribution of TIGAR-O risk factors in chronic pancreatitis (CP) patients. The NAPS-2 Continuation and Validation (NAPS2-CV) study prospectively enrolled 521 CP patients from 13 US centers from 2008 to 2012. CP was defined by definitive changes in imaging, endoscopy, or histology. Data were analyzed after stratification by demographic factors, physician-defined etiology, participating center, and TIGAR-O risk factors. Demographics and physician-defined etiology in the NAPS2-CV study were similar to the original NAPS2 study. Mean age was 53 years (IQR 43, 62) with 55% males and 87% white. Overall, alcohol was the single most common etiology (46%) followed by idiopathic etiology (24%). Alcohol etiology was significantly more common in males, middle-aged (35-65 years), and non-whites. Females and elderly (≥65 years) were more likely to have idiopathic etiology, while younger patients (<35 years) to have genetic etiology. Variability in etiology was noted by participating centers (e.g., alcohol etiology ranged from 27 to 67% among centers enrolling ≥25 patients). Smoking was the most commonly identified (59%) risk factor followed by alcohol (53%), idiopathic (30%), obstructive (19%), and hyperlipidemia (13%). The presence of multiple TIGAR-O risk factors was common, with 1, 2, ≥3 risk factors observed in 27.6, 47.6, and 23.6% of the cohort, respectively. Our data validate the current epidemiologic trends in CP. Alcohol remains the most common physician-defined etiology, while smoking was the most commonly identified TIGAR-O risk factor. Identification of multiple risk factors suggests CP to be a complex disease.

Laboratory mice develop naturally occurring lesions that affect biomedical research. Hydronephrosis is a recognized pathologic abnormality of the mouse kidney. Acquired hydronephrosis can affect any mouse, as it is caused by any naturally occurring disease that impairs free urine flow. Many etiologies leading to this condition are of particular significance to aging mice. Non-invasive ultrasound imaging detects renal pelvic dilation, renal enlargement, and parenchymal loss for pre-mortem identification of this condition. High-frequency ultrasound transducers produce high-resolution images of small structures, ideal for detecting organ pathology in mice. Using a 40 MHz linear array transducer, we obtained high-resolution images of a diversity of pathologic lesions occurring within the abdomen of seven geriatric mice with acquired hydronephrosis that enabled a determination of the underlying etiology. Etiologies diagnosed from the imaging results include pyelonephritis, neoplasia, urolithiasis, mouse urologic syndrome, and spontaneous hydronephrosis, and were confirmed at necropsy. A retrospective review of abdominal scans from an additional 149 aging mice shows that the most common etiologies associated with acquired hydronephrosis are mouse urologic syndrome and abdominal neoplasia. This report highlights the utility of high-frequency ultrasound for surveying research mice for age-related pathology, and is the first comprehensive report of multiple cases of acquired hydronephrosis in mice.

Female sexuality

Sex is a motive force bringing a man and a woman into intimate contact. Sexuality is a central aspect of being human throughout life and encompasses sex, gender identities and roles, sexual orientation, eroticism, pleasure, intimacy, and reproduction. Sexuality is experienced and expressed in thoughts, fantasies, desires, beliefs, attitudes, values, behaviors, practices, roles and relationships. Though generally, women are sexually active during adolescence, they reach their peak orgasmic frequency in their 30 s, and have a constant level of sexual capacity up to the age of 55 with little evidence that aging affects it in later life. Desire, arousal, and orgasm are the three principle stages of the sexual response cycle. Each stage is associated with unique physiological changes. Females are commonly affected by various disorders in relation to this sexual response cycle. The prevalence is generally as high as 35–40%. There are a wide range of etiological factors like age, relationship with a partner, psychiatric and medical disorders, psychotropic and other medication. Counseling to overcome stigma and enhance awareness on sexuality is an essential step in management. There are several effective psychological and pharmacological therapeutic approaches to treat female sexual disorders. This article is a review of female sexuality. PMID:26330647

Electrolyte imbalance is a common problem affecting the elderly. Increased number of comorbidities and frequent use of drugs may contribute to increased risk of hypokalemia in the elderly. This study was performed to investigate the prevalence of community-acquired hypokalemia (CAH), risk factors for its development, related factors with hypokalemia, and morbidities and all-cause mortality rates (MR) of CAH in the elderly patients. Total of 36,361 patients aged above 65 years were screened retrospectively. Group 1 consisted of 269 elderly patients with potassium level ≤3.5 mmol/L, and group 2 (control group) consisted of 182 subjects with potassium level between 3.6 and 5.5 mmol/L. Etiologic factors of CAH, presence of comorbidities, duration of hospital stay, hospital cost, and clinical outcomes were recorded. Prevalence of hypokalemia was found 3.24% in patients aged above 65 years. Duration of hospital stay, presence of ≥2 comorbid diseases, hospital cost, and MR were significantly higher in group 1 compared to group 2 (p < 0.001 for all). Loop diuretics, hydrochlorothiazides, beta agonists, inadequate oral intake, and female gender were all independent risk factors for CAH in elderly patients. Patients with ≥2 comorbid diseases were found to have greater risk of hypokalemia than the patients with <2 comorbidities. Length of hospital stay, hospital cost, and MR were higher in elderly with CAH. Female gender, hydrochlorothiazides, loop diuretics, and ≥2 comorbid diseases are the leading risk factors associated with CAH in elderly.

Pruritic skin diseases are common in cats and demand rigorous diagnostic workup for finding an underlying etiology. Measurement of a serum allergen-specific IgE in a pruritic cat is often used to make or confirm the diagnosis of a skin hypersensitivity disease, although current evidence suggests that elevated allergen-specific IgE do not always correlate with a clinical disease and vice versa. The aim of the study was to to assess the possible influence of age, deworming status, lifestyle, flea treatment, and gender on allergen-specific IgE levels and to evaluate the reliability of IgE testing in predicting the final diagnosis of a pruritic cat. For this purpose sera of 179 cats with pruritus of different causes and 20 healthy cats were evaluated for allergen-specific IgE against environmental, food and flea allergens using the Fc-epsilon receptor based enzyme-linked immunosorbent assay (ELISA) test. The results of the study showed positive correlation between age, outdoor life style, absence of deworming, absence of flea control measures and levels of allergen-specific IgE. Gender and living area (urban versus rural) did not seem to affect the formation of allergen-specific IgE. According to these findings, evaluating allergen-specific IgE levels, is not a reliable test to diagnose hypersensitivity to food or environmental allergens in cats. On the contrary, this test can be successfully used for diagnosing feline flea bite hypersensitivity. PMID:22754094

There has been a significant increase in the participation of women in sports at all levels, especially after the enactment of the Title IX Education Amendment in 1972. This increased participation at all levels has resulted in more women sustaining sports injuries. Data on sex- and gender-based differences in all organ systems, including the musculoskeletal system, are beign gathered. It is important to review some of the areas of sex- and gender-based differences in sports injuries for which there is significant research, such as osteoporosis, the female athlete triad, and anterior cruciate ligament injuries. It is also necessary to examine those areas in which more information is needed, such as injuries to the shoulder, foot, and ankle.

To explore whether health-related quality of life (HRQOL) can be predicted by pain, age, Gross Motor Function Classification System (GMFCS) level, and sex in children with cerebral palsy (CP) and whether different pain etiologies have varying effects on HRQOL. Children with CP aged 3 to 19 years and their caregivers were consecutively recruited. Caregivers reported their child's pain (Health Utilities Index 3 [HUI3] pain subset) and HRQOL (DISABKIDS questionnaires). Physicians identified pain etiologies. A multiple linear regression model determined whether pain, GMFCS level, sex, and age predicted HRQOL. An ANOVA evaluated the effects of pain etiologies on HRQOL. Three hundred and forty-four participants were approached and 87% (n=300) participated. Sufficient data were available on 248 (72% of total sample). Sixty-six participants (27%) formed the pain group with HUI3 pain scores of at least 3. The presence of pain and increasing age significantly negatively predicted HRQOL (p<0.001, R(2) =0.141), while GMFCS and sex did not. Musculoskeletal deformity (24%) and hypertonia (18%) were the most frequent pain causes. HRQOL statistically differed depending on the pain etiology (p=0.028) with musculoskeletal deformity showing the lowest mean HRQOL. The presence of pain and increasing age negatively predict HRQOL in CP. musculoskeletal deformity has the greatest negative impact on HRQOL. © 2015 Mac Keith Press.

Environment, health, and gender in Latin America: trends and research issues.

PubMed

Wasserman, E

1999-04-01

Over the past several decades, Latin America underwent rapid urbanization, a demographic shift led by women. Women now make up almost half of the economically active population and the feminization of urban poverty is being reported as well. The majority of men and women now work in unregulated, unorganized "informal" and nontraditional industries and services lacking occupational and environmental regulations. There is a marked paucity of health studies examining possible hazardous exposures, especially where gender-based social etiologies are concerned. This is true even in concentrated industries such as manufacturing assembly plants and in potentially hazardous occupations in mining and nontraditional agricultural exports, for which data from other disciplines are available and raise serious concerns. The need to ensure enough jobs at sufficient levels of income to alleviate poverty will remain a major challenge at the turn of the century and the environmental health implications of doing so could be far-reaching. What data are available and, more strikingly, the paucity of published epidemiologic studies warrant deep concern and support calls for urgent, multidisciplinary research into the health effects of the combined, multiple assaults of hazardous industrial waste, inadequate water and sewage treatment, and occupational exposures. Given the complex and varied work roles of women, the information reviewed also points to the need to conduct such research in the region within a social-etiologic framework of gender analysis.

The aim of this study is to investigate the incidence and pattern of traumatic fractures (TFs) as a result of falls in a population of children and adolescents (≤18 years old) in China.This was a cross-sectional study. We retrospectively reviewed 1412 patients who were children and adolescents with TFs as a result of falls admitted to our university-affiliated hospitals in China from 2001 to 2010. Etiologies included high fall (height ≥2) and low fall (height <2 m). The incidence and pattern were summarized with respect to different age groups, year of admission, etiologies, genders, and the neurological function.This study enrolled 1054 males (74.6%) and 358 females (25.4%) aged 10.8 ± 4.7 years. The etiologies were low fall (1059, 75.0%) and high fall (353, 25.0%). There were 2073 fractures in total and 92 patients (6.5%) presented with multiple fractures. The most common fracture sites were upper extremity fractures in 814 patients (57.6%) and lower extremity fractures in 383 patients (27.1%), followed by craniofacial fractures in 233 patients (16.5%). A total of 231 (16.4%) patients suffered a nerve injury. The frequencies of early and late complications/associated injuries were 19.5% (n = 275) and 9.2% (n = 130). The frequencies of emergency admission, nerve injury, spinal fracture, lower extremity fractures, craniofacial fracture, sternum and rib fracture, and early complications/ASOIs were significantly larger in high fall than low fall (all P <.001, respectively). The frequencies of medical insurance rate (P = .042) and upper extremity fractures (P <.001) were significantly larger in low fall than high fall. The frequencies of spinal fracture (P = .039), lower extremity fractures (P = .048), and craniofacial fracture (P = .041) were significantly larger in female than the male patients. The frequency of upper extremity fractures (P <.001) and the mean age (P <.001) was significantly larger in male than female patients. The frequencies of emergency admission, high fall, spinal fracture, and craniofacial fracture were significantly larger in patients with nerve injury than other patients without nerve injury (all P <.001, respectively).Low falls and upper extremity fractures were the most common etiologies and sites, respectively. High fall, spinal fracture and craniofacial fracture were risk factors for nerve injury. Therefore, we should focus on patients who were caused by high fall and presented with spinal and craniofacial fracture to determine the presence of a nerve injury so that we can provide early, timely diagnosis and targeted treatment to children.

Acquired neutropenia in immunocompetent children is common and its differential diagnosis ranges from benign causes to life-threatening diseases. We described the etiology, clinical picture and outcome of new onset neutropenia in immunocompetent children assessed in the emergency department and hospitalized at our medical center. Previously healthy children admitted with neutropenia (absolute neutrophil count [ANC] <1.5 x 10/L) were included. Serious bacterial infections (SBI) were defined as culture-positive blood, urine, CSF, articular fluid or stool infections, pneumonia, Brucellosis and Rickettsiosis. 601 patients (aged 5 days-202 months) were enrolled; 3 (0.5%), 48 (8%), 165 (27.5%) and 385 (64%) had ANCs <0.2, 0.2-0.5, 0.5-1.0 and 1.0-1.5 x 10/L, respectively. Associated leukopenia and thrombocytopenia were diagnosed in 186 (39%) and 71 (11.8%) patients. 316/601 (52.6%) and 519/601 (86.4%) were <2 or 36 months of age, respectively. Fever at admission was present in 27.6% patients. SBIs were diagnosed in 106 (17.6) patients. Brucellosis and rickettsiosis were diagnosed in 8/52 (15.4%) and 9/39 (23.1%) tests obtained. RSV was diagnosed in 17/33 (51.5%) nasal washes. An infectious etiology was determined in 171 (28.5%) patients. Acute leukemia was diagnosed in 6 patients. A significant correlation was found between resolution of neutropenia and patient age, infectious etiology and severity of neutropenia. 1. Severe neutropenia was rare; 2. More than half of patients were <2 months of age; 3. An infectious etiology was diagnosed in a high number of patients and SBIs were frequent; 4. Brucella spp. and rickettsial infections were frequent etiologies associated with neutropenia in our setting.

Vulvovaginitis accounts for 25% of all pediatric gynecology consultations. To assess the etiology of vulvovaginitis based on age and Tanner staging of breast development. Descriptive, cross-sectional study conducted between January 1st and December 31st, 2011. Patients with vulvovaginitis were assessed based on two outcome measures: age group (GI: 0 to 8.9 years old, GII: 9 to 15.9 years old, and GIII: 16 to 18 years old), and the Tanner staging of breast development (I, II-III, IV-V). Results. Two hundred and twenty-nine patients were included, 78 girls in the GI group, 134 in the GII group, and 17 in the GIII group; 81 girls were classified as TI, 36 as TII-III, and 112 as TIV-V based on Tanner staging. Shigella and Oxyuris were the most commonly found etiologic agents in younger girls. Candida albicans, other Candida species, Gardnerella and Ureaplasma urealyticum were the germs most commonly observed in older patients. Oxyuris was predominant in prepubertal girls, while Candida albicans, in postpubertal girls. Hormonal influence was more relevant than the patient's age in terms of vulvovaginitis etiology.

A genetically informed longitudinal cross-lagged model was applied to twin data to explore etiological links between difficult temperament and negative parenting in early childhood. The sample comprised 313 monozygotic (MZ) and dizygotic (DZ) twin pairs. Difficult temperament and negative parenting were assessed at ages 2 and 3 using parent ratings. Both constructs were interrelated within and across age (rs .34-.47) and showed substantial stability (rs .65-.68). Difficult temperament and negative parenting were influenced by genetic and environmental factors at ages 2 and 3. The genetic and nonshared environmental correlations (rs .21-.76) at both ages suggest overlap at the level of etiology between the phenotypes. Significant bidirectional associations between difficult temperament and negative parenting were found. The cross-lagged association from difficult temperament at age 2 to negative parenting at age 3 and from negative parenting at age 2 and difficult temperament at age 3 were due to genetic, shared environmental, and nonshared environmental factors. Substantial novel genetic and nonshared environmental influences emerged at age 3 and suggest change in the etiology of these constructs over time. © 2015 John Wiley & Sons Ltd.

Epileptic encephalopathy with electrical status epilepticus during sleep is an age-related and self-limited disorder. The present study analyzed the etiology, demographics, and pathogenesis of patients with electrical status epilepticus during sleep to provide information on the diagnosis and therapy of this syndrome. The etiologies of epileptic encephalopathy with electrical status epilepticus during sleep in patients admitted in Chinese People's Liberation Army General Hospital from 2009 to 2014 were retrospectively analyzed. Patients were classified into the genetic, structural-metabolic, and unknown groups according to the etiology. Demographics and clinical characteristics of all the patients were then analyzed and compared among groups. The etiologies of epileptic encephalopathy with electrical status epilepticus during sleep in 75 patients mainly included benign childhood epilepsy with centrotemporal spikes, Landau-Kleffner syndrome, polymicrogyria, and migration disorders. Age at onset of epilepsy did not show a specific pattern, but age at onset of epileptic encephalopathy with electrical status epilepticus during sleep was concentrated at age 6-9 years. The mean age at onset of epilepsy in the genetic group was significantly older than that in the structural-metabolic group (P < 0.05). Age at onset of epileptic encephalopathy with electrical status epilepticus during sleep did not significantly differ between the two groups. Electrical status epilepticus during sleep is an epileptic encephalopathy related to brain development and presents an age-dependent occurrence. Copyright © 2016 Elsevier Inc. All rights reserved.

Environmental factors play an important role in the etiology of overweight (S) and obesity (O), constituting the "obesogenic environment". The objectives of the present study are: a) to estimate overweight and obesity prevalences in 3 to 14 years-old schoolchildren from Brandsen (Provincia de Buenos Aires), and b) to analyze the probability of occurrence of overweight and obesity in relation to the socioenvironmental conditions of resident. Weight and height were measured in 989 boys and girls aged 3 to 14 years. S and O were estimated following the criteria suggested by the International Obesity Task Force. The prevalences of S and O were compared between genders and ages. The socio- environmental information was gathered according to surveys and processed by Categorical Principal Components Analysis (catPCA). Generalized Linear Model (link logit) against the variables S and O was employed. S was found in 15,8% of schoolchildren and O in 7,2%. None significative statistics differences between both genders and ages, were found. The first axis of the catPCA discriminated the cases that presented better socio-environmental conditions with positive values and those with more unfavorable conditions with negatives values. Higher probability of obese children was associated with better socio-environmental conditions (higher educational level of parents, higher income and better access to public services), and higher probability of overweight children was associated with less favored environments. The schoolchildren population of Brandsen presents high overweight and obesity prevalences. The chance of presenting overweight is higher in children from households with adverse socio-environmental conditions. On the contrary, obese children are to be more found in households which have more favorable socio-environmental conditions.

Gender-moderated gene–environment interactions are rarely explored, raising concerns about inaccurate specification of etiological models and inferential errors. The current study examined the influence of gender, negative and positive daily life events, and GABRA2 genotype (SNP rs279871) on alcohol dependence, testing two- and three-way interactions between these variables using multilevel regression models fit to data from 2,281 White participants in the Collaborative Study on the Genetics of Alcoholism. Significant direct effects of variables of interest were identified, as well as gender-specific moderation of genetic risk on this SNP by social experiences. Higher levels of positive life events were protective for men with the high-risk genotype, but not among men with the low-risk genotype or women, regardless of genotype. Our findings support the disinhibition theory of alcohol dependence, suggesting that gender differences in social norms, constraints and opportunities, and behavioral undercontrol may explain men and women’s distinct patterns of association.

2013-07-01

Sociocontextual factors such as gender and power play an important role in the etiology of affairs and in recovery from them, yet it is unclear how current treatment models address these issues. Drawing on feminist epistemology, this study utilized a grounded theory analysis of 29 scholarly articles and books on infidelity treatment published between 2000 and 2010 to identify the circumstances under which gender and power issues were or were not part of treatment. We found five conditions that limit attention to gender and power: (a) speaking (or assuming) as though partners are equal, (b) reframing infidelity as a relationship problem, (c) limiting discussion of societal context to background, (d) not considering how societal gender and power patterns impact relationship dynamics, and (e) limiting discussion of ethics on how to position around infidelity. Analysis explored how each occurred across three phases of couple therapy. The findings provide a useful foundation for a sociocontextual framework for infidelity treatment. © 2012 American Association for Marriage and Family Therapy.

Beyond the Caster Semenya controversy: the case of the use of genetics for gender testing in sport.

Caster Semenya won the eight-hundred-meter title in the Berlin World Athletics Championships in 2009. Few hours after, Caster was at the center of a harsh contestation on gender. The International Association of Athletics Federations started an investigation, which was not respectful of her privacy. Caster's case highlights the need for an improvement in the awareness of genetic counseling principles amongst professionals, the public and various stakeholders. We critically examine the historical steps of gender verification in the Olympics, the violation of genetic counseling principles in Caster's case and outline some reflections on the complexity of the genetics of Disorders of sex development (DSD). Variability in both genotypes and phenotypes in DSD may not allow any etiological or functional classification at this point in time that could permit uncontroversial gender verification for fairer sport participation. We strongly suggest revisiting the pertinence of gender verification, and the process whereby this is done.

Background There are very limited data on children with pneumonia in Mali. The objective was to assess the etiology and factors associated with community-acquired pneumonia in hospitalized children <5 years of age in Mali. Methods A prospective hospital-based case-control study was implemented in the Pediatric department of Gabriel Touré University Hospital at Bamako, Mali, between July 2011-December 2012. Cases were children with radiologically-confirmed pneumonia; Controls were hospitalized children without respiratory features, matched for age and period. Respiratory specimens, were collected to identify 19 viruses and 5 bacteria. Whole blood was collected from cases only. Factors associated with pneumonia were assessed by multivariate logistic regression. Results Overall, 118 cases and 98 controls were analyzed; 44.1% were female, median age was 11 months. Among pneumonia cases, 30.5% were hypoxemic at admission, mortality was 4.2%. Pneumonia cases differed from the controls regarding clinical signs and symptoms but not in terms of past medical history. Multivariate analysis of nasal swab findings disclosed that S. pneumoniae (adjusted odds ratio [aOR] = 3.4, 95% confidence interval [95% CI]: 1.6–7.0), human metapneumovirus (aOR = 17.2, 95% CI: 2.0–151.4), respiratory syncytial virus [RSV] (aOR = 7.4, 95% CI: 2.3–23.3), and influenza A virus (aOR = 10.7, 95% CI: 1.0–112.2) were associated with pneumonia, independently of patient age, gender, period, and other pathogens. Distribution of S. pneumoniae and RSV differed by season with higher rates of S. pneumoniae in January-June and of RSV in July-September. Pneumococcal serotypes 1 and 5 were more frequent in pneumonia cases than in the controls (P = 0.009, and P = 0.04, respectively). Conclusions In this non-PCV population from Mali, pneumonia in children was mainly attributed to S. pneumoniae, RSV, human metapneumovirus, and influenza A virus. Increased pneumococcal conjugate vaccine coverage in children could significantly reduce the burden of pneumonia in sub-Saharan African countries. PMID:26696249

An alarming increase in chronic kidney disease with unknown etiology (CKDu) has recently been reported in several provinces in Sri Lanka and chronic exposures to toxic trace elements were blamed for the etiology of this disease. Keratinized matrices such as hair and nails were investigated to determine the possible link between CKDu and toxic element exposures. Elements Li, B, Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Sr, Mo, Cd, Ba, Hg and Pb of hair and nails of patients and age that matched healthy controls were determined with Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The results showed that trace element contents in the hair of patients varies in the order of Zn>Fe>Al>Mn>Cu>Ba>Sr>Ni>Pb>Cr>B>Hg>Se>Mo>Co>As>Li>Cd while Fe>Al>Zn>Ni>Cu>Mn>Cr>Ba>Sr>B>Pb>Se>Mo>Co>Hg>Li>As>Cd in nail samples. The hair As levels of 0.007-0.165μgg -1 were found in CKDu subjects. However, no significant difference was observed between cases and controls. The total Se content in hair of CKDu subjects ranged from 0.043 to 0.513μgg -1 while it was varied from 0.031 to 1.15μgg -1 in controls. Selenium in nail samples varied from 0.037μgg -1 to 4.10μgg -1 in CKDu subjects and from 0.042μgg -1 to 2.19μgg -1 in controls. This study implies that substantial proportions of Sri Lankan population are Se deficient irrespective of gender, age and occupational exposure. Although some cutaneous manifestations were observed in patient subjects, chemical analyses of hair and nails indicated that patients were not exposed to toxic levels of arsenic or the other studied toxic elements. Therefore the early suggested causative factors such as exposure to environmental As and Cd, can be ruled out. Copyright © 2016 Elsevier GmbH. All rights reserved.

There is no published systematic review on the etiologies of chronic cough or the relationship between OSA and chronic cough in children aged ≤ 14 years. We thus undertook a systematic review based on key questions (KQs) using the Population, Intervention, Comparison, Outcome format. The KQs follow: Among children with chronic (> 4 weeks) cough (KQ 1) are the common etiologies different from those in adults? (KQ 2) Are the common etiologies age or setting dependent, or both? (KQ 3) Is OSA a cause of chronic cough in children? We used the CHEST Expert Cough Panel's protocol and the American College of Chest Physicians (CHEST) methodological guidelines and Grading of Recommendations Assessment, Development, and Evaluation framework. Data from the systematic reviews in conjunction with patients' values and preferences and the clinical context were used to form recommendations. Delphi methodology was used to obtain consensus. Combining KQs 1 and 2, we found moderate-level evidence from 10 prospective studies that the etiologies of cough in children are different from those in adults and are setting dependent. Data from three studies found that common etiologies of cough in young children were different from those in older children. However, data relating sleep abnormalities to chronic cough in children were found only in case studies. There is moderate-quality evidence that common etiologies of chronic cough in children are different from those in adults and are dependent on age and setting. As there are few data relating OSA and chronic cough in children, the panel suggested that these children should be managed in accordance with pediatric sleep guidelines. Copyright © 2017.

Behçet’s syndrome (BS) is a multisystem vasculitis that presents with a variety of mucocutaneous manifestations such as oral and genital ulcers, papulopustular lesions and erythema nodosum as well as ocular, vascular, gastrointestinal and nervous system involvement. Although it occurs worldwide, it is especially prevalent in the Far East and around the Mediterranean Sea. Male gender and younger age at disease onset are associated with a more severe disease course. The management of BS depends on the severity of symptoms. If untreated, morbidity and mortality are considerably high in patients with major organ involvement. Multidisciplinary patient care is essential for the management of BS, as it is for other multisystem diseases. Rheumatologists, dermatologists, ophthalmologists, neurologists, cardiovascular surgeons and gastroenterologists are members of the multidisciplinary team. In this study, we reviewed the epidemiology, etiology, diagnostic criteria sets, clinical findings and treatment of BS and highlighted the importance of the multidisciplinary team in the management of BS.

Based on hospital discharges in 1001-2010, we calculated risk of tumours with an elevated occupational and environmental etiological fraction by health district of residence within the Local Health Unit (LHU) N. 8 of Sardinia. With reference to the age and gender-specific hospitalization rates of the whole LHU, residents in the urban Cagliari health district showed an excess risk of haemolymphopoietic cancer (RR = 1.07; 95% CI 1.03-1.12) and bladder cancer (RR = 1.10; 95% CI 1.05-1.16); in both instances, risks were higher among female residents. The highest excess risk for lung cancer was observed among residents in the Quartu-Parteolla health district (RR = 1.13; 95% CI 1.05-1.21), and it was slightly higher among male residents. The results appear to confirm the role of urban factors in increasing cancer risk.

Difficulties with swallowing may be both persistent and life threatening for the majority of those who experience it irrespective of age, gender, and race. The purpose of this review is to define oropharyngeal dysphagia and describe its relationship to cervical spine disorders and postural disturbances due to either congenital or acquired disorders. The etiology and diagnosis of dysphagia are analyzed, focusing on cervical spine pathology associated with dysphagia as severe cervical spine disorders and postural disturbances largely have been held accountable for deglutition disorders. Scoliosis, kyphosis–lordosis, and osteophytes are the primary focus of this review in an attempt to elucidate the link between cervical spine disorders and dysphagia. It is important for physicians to be knowledgeable about what triggers oropharyngeal dysphagia in cases of cervical spine and postural disorders. Moreover, the optimum treatment for dysphagia, including the use of therapeutic maneuvers during deglutition, neck exercises, and surgical treatment, is discussed.

Ischemic stroke and coronary heart disease (CHD) may share genetic factors contributing to a common etiology. This study investigates whether 51 single nucleotide polymorphisms (SNPs) associated with CHD in multiple antecedent studies are associated with incident ischemic stroke in the Atherosclerosis Risk in Communities (ARIC) study. From the multiethnic ARIC cohort of 14,215 individuals, 495 validated ischemic strokes were identified. Cox proportional hazards models, adjusted for age and gender, identified three SNPs in Whites and two SNPs in Blacks associated with incident stroke (p

Improving knowledge regarding injuries sustained by pediatric dancers is important in order to better understand injury risk. The aim of this study is to analyze dance injury etiology and body area by age in a cohort of young female dancers presenting to a pediatric sports/dance medicine clinic. The cross-sectional epidemiological study of a 5% probability sample of dancers evaluated between 1/1/2000 and 12/31/2009 with a musculoskeletal injury requiring physician evaluation. A total of 2,133 charts were reviewed from which 171 female dancers 8-17 years old (mean age 14.7 years) were identified. Data were stratified by age, < 12 years and ≥ 12 years, and analyzed based on injury body area, type, and etiology. Fisher's exact test was used to determine statistical significance. Injuries sustained by dancers in the younger age category (< 12 years) were largely to the foot-ankle/lower leg/knee (93.3%) versus thigh-hip/spine/upper extremity (6.7%). In comparison, dancers in the older age group (≥ 12 years) had a large proportion of injuries to the foot-ankle/lower leg/knee (67.3%) as well, but had a notably larger fraction of injuries to the thigh-hip/spine/upper extremity (32.7%; p = 0.04). Approximately two-thirds of the injuries sustained in the younger age group (< 12 years) were classified as bony. In comparison, injuries in the older age group (≥ 12 years) were roughly half bony and half soft tissue (51.3% and 48.7%, respectively; p = 0.29). Most injuries were overuse in etiology for both younger and older age groups (86.7% and 82.1%, respectively; p = 1.00). Through puberty, there was a decline in the injuries to the foot-ankle/lower leg/knee. Conversely, there was an increase in the thigh/hip-pelvis/spine/upper extremity injuries through growth. Injuries to young female dancers in this study cohort were mostly categorized as overuse in etiology, and differed by the age group and the body area. Increased information regarding dance injuries can help guide future injury prevention efforts.

This study prospectively evaluated the prevalence and risk factors of tinea unguium and tinea pedis in the general adult population in Madrid, Spain. One thousand subjects were clinically examined, and samples of nails and scales from the interdigital spaces of the feet were taken from those patients presenting with signs or symptoms of onychomycosis and/or tinea pedis, respectively. In addition, a sample from the fourth interdigital space of both feet was collected from all individuals with a piece of sterilized wool carpet. Tinea unguium was defined as a positive direct examination with potassium hydroxide and culture of the etiological agent from subjects with clinically abnormal nails. Patients with positive dermatophyte cultures of foot specimens were considered to have tinea pedis. The prevalence of tinea unguium was 2.8% (4.0% for men and 1.7% for women), and the prevalence of tinea pedis was 2.9% (4.2% for men and 1.7% for women). The etiological agents of tinea unguium were identified as Trichopyton rubrum (82.1%), followed by Trichopyton mentagrophytes var. interdigitale (14.3%) and Trichopyton tonsurans (3.5%). Trichophyton rubrum (44.8%) and Trichophyton mentagrophytes (44.8%), followed by Epidermophyton floccosum (7%) and T. tonsurans (3.4%), were the organisms isolated from patients with tinea pedis. The percentage of subjects who suffered simultaneously from both diseases was 1.1% (1.7% for men and 0.6% for women). In a multivariate logistic regression analysis, age (relative risk [RR], 1.03) and gender (RR, 2.50) were independent risk factors for tinea unguium, while only gender (RR, 2.65) was predictive for the occurrence of tinea pedis. In both analyses, the presence of one of the two conditions was associated with a higher risk for the appearance of the other disease (RR, >25). PMID:10970362

in Taranto IPS (Italian polluted site, made up of 2 municipalities) the Decree defining site boundaries lists the presence of a refinery, a steel plant, a harbour area and waste landfills together with illegal dumping sites. Previous environmental and epidemiological investigations in the area documented the presence of environmental contamination and increased mortality from respiratory and cardiovascular diseases as well as a number of cancer sites; for these same health outcomes the cohort study of residents showed increased risk both in terms of mortality and morbidity. to describe the health status of residents in Taranto IPS analyzing different health indicators available at municipal level, i.e. mortality (2003-2009), mortality time trend (1980-2008) and cancer incidence (2006-2007). the analyses were carried out for residents in Taranto IPS. Mortality update (SENTIERI Project, 2003-2009) regards 63 single or grouped causes (all ages, both genders); for a selection of causes 0-1 and 0-14 age classes were analyzed (both genders combined). Standardized mortality ratio crude (SMR) and deprivation adjusted together with 90% confidence intervals (90%CI) were computed using regional rates for comparison. Mortality time trend (1980-2008, triennial intervals) were analyzed calculating standardized rates (0-99 years, both genders, per 100,000, Italian population at 2001 Census as reference) and 90%CI. Time trends were computed for all causes, all neoplasms (and lung cancer), cardiovascular diseases (and ischemic heart diseases), respiratory diseases (also acute and chronic) and all causes infant mortality (both genders combined). For cancer incidence (2006-2007) Standardized incidence ratio (SIR) and 90%CI were calculated for both genders; incidence rates of cancer registries of the macroarea South and Islands (2005-2007) and rates of Taranto Province excluding SIN municipalities (2006-2007) were used for comparison. in Taranto IPS mortality among men is in excess in both periods (SENTIERI Project 1995-2002 and 2003-2009) for all causes, all neoplasms (including lung and pleural cancer), dementia, cardiovascular diseases (including hypertension and ischemic heart diseases), respiratory diseases (including the acute ones) and digestive diseases (including liver cirrhosis). All causes infant mortality is in excess in both periods. Time trends show that Taranto IPS rates are higher than regional average in the majority of time intervals for most causes in both genders. Rates are often higher than national average form any triennial intervals. Among males, over the whole period, mortality in Taranto IPS is higher than regional and national average for causes as lung cancer, diseases of the respiratory system, including the chronic ones. Among females, since the early Nineties, lung cancer and ischemic heart diseases are in excess in Taranto IPS. Also infant mortality is higher for the whole period in Taranto IPS than regional and national averages. Cancer incidence results show excesses for cancer sites already indicated by mortality data. mortality analyzed in the context of SENTIERI Project (1995-2002 and 2003-2009), time trend mortality (1980-2008) and cancer incidence (2006- 2007) show, in both genders, excesses for causes for which an etiologic role of environmental exposure present in Taranto IPS are either ascertained or suspected on the basis of a priori evaluation of the epidemiological evidence. The finding of excess infant mortality is of the utmost importance in public health terms. Most diseases showing an increased risk have multifactorial etiology, therefore interventions of proven efficacy, such as smoking cessation, food education, measures for cardiovascular risk reduction and breast cancer and colon screening programmes should be planned. To build a climate of confidence and trust between citizens and public institutions study results and public health actions are to be communicated objectively and transparently.

Coronary artery aneurysm (CAA) with concomitant aneurysms at multiple sites is quite unusual and rare. The characteristics and the etiology of this phenomenon are unknown. Herein, we present a case with right coronary aneurysm with concomitant abdominal aorta as well as right renal artery aneurysm. A systematic review of the literatures regarding CAA with other coexisting aneurysms at multiple locations was also conducted on Medline and Embase databases. A total of 76 patients (male gender: 58; age: 37.4 ± 26.5) including the present case were included in the final study. The most common etiology of CAA with multiple aneurysms was Kawasaki (43.3%) and atherosclerotic disease (16.4%). CAA was the most frequently found at the right coronary artery (62.7%), following, left anterior descending (51%), left main (43.1%), and left circumflex (35.3%). The most common concomitant aneurysms were abdominal aorta (52.6%) and iliac artery (50%). In addition, 60.5% of the patients had an involved bilateral peripheral artery. CAA with coexisting systemic aneurysms in multiple sites is quite rare. And it usually involves multiple aneurysms at the coronary and bilateral peripheral arteries simultaneously. Currently, there are no general consensus regarding the clinical characteristics, diagnostic method, and treatment of these cases. Copyright © 2017 The Authors.

This study aims to evaluate the demographic and clinical characteristics of patients with idiopathic and non-idiopathic vocal cord paralysis (VCP). This retrospective cohort was performed on data extracted from medical files of 92 consecutive patients (43 males, 49 females; median age 52.1±23.1 years; min. 1 - max. 87) with VCP diagnosed in the otorhinolaryngology department between April 2012 and December 2015. Diagnoses associated with VCP, side of involvement (right, left or bilateral) and previous medical histories were noted and compared between patients with idiopathic and non-idiopathic VCP. Vocal cord paralysis occurred on the left side (n=56, 60.9%), right side (n=28, 30.4%) or bilaterally (n=8, 8.7%). A clinical entity related with VCP was identified in 63 patients (68.5%), while 29 (31.5%) patients had idiopathic VCP. Most common etiologies for VCP were thyroid surgery (n=32, 34.8%), cardiovascular surgery (n=9, 9.8%), lung cancer (n=6, 6.5%) and cardiac anomalies (n=4, 4.3%), respectively. Patients with idiopathic VCP were significantly older (p<0.001), while gender distribution (p=0.121) and side of involvement (p=0.340) did not differ between two groups. Vocal cord paralysis is a relatively common clinical entity with substantial rate of morbidity. Identification of the underlying etiology and awareness on the clinical characteristics are keystones for foreseeing complications and determining the appropriate therapeutic modality.

Sex and gender differences in substance use disorders.

2017-11-10

The gender gap in substance use disorders (SUDs), characterized by greater prevalence in men, is narrowing, highlighting the importance of understanding sex and gender differences in SUD etiology and maintenance. In this critical review, we provide an overview of sex/gender differences in the biology, epidemiology and treatment of SUDs. Biological sex differences are evident across an array of systems, including brain structure and function, endocrine function, and metabolic function. Gender (i.e., environmentally and socioculturally defined roles for men and women) also contributes to the initiation and course of substance use and SUDs. Adverse medical, psychiatric, and functional consequences associated with SUDs are often more severe in women. However, men and women do not substantively differ with respect to SUD treatment outcomes. Although several trends are beginning to emerge in the literature, findings on sex and gender differences in SUDs are complicated by the interacting contributions of biological and environmental factors. Future research is needed to further elucidate sex and gender differences, especially focusing on hormonal factors in SUD course and treatment outcomes; research translating findings between animal and human models; and gender differences in understudied populations, such as those with co-occurring psychiatric disorders and gender-specific populations, such as pregnant women.

2010-12-01

To investigate the epidemiology of acute respiratory tract infections (ARIs) in children younger than 24 months old with hemodynamically significant congenital heart diseases. Primary aim: incidence of hospital admission due to ARI. Secondary aims: risk factors, etiologic agents, clinical outcomes, and usefulness of preventive measures. Prospective, multicenter, epidemiologic study conducted in 57 Spanish hospitals covering four 7-month seasons (2004-2008). A total of 2613 patients were eligible for the study. Three hundred fifty-four patients (13.5%) (95% confidence interval: 12.3-14.9) required a total of 453 hospital admissions. Clinical diagnoses: bronchiolitis (54.1%), upper respiratory tract infection (21%), pneumonia (19.9%), and others (17.4%). Median length of hospital stay: 7.0 days. No etiologic agent was identified in two-thirds of the patients. In the remaining patients either a single agent (26.8%) or polymicrobial infection (5%) was identified. Respiratory syncytial virus (RSV) was the agent that was most commonly found (3.8% specific hospitalization rate). Children receiving adequate RSV prophylaxis (90.5%) had a 58.2% (95% confidence interval: 37.6-78.3) reduction in RSV hospitalization. Risk factors for admission included malnourishment, infant age, male gender, chromosome alterations, wheezing, inadequate RSV prophylaxis fulfillment, and siblings <11 years of age. Pediatric intensive care unit care was required in 21.8% of the admissions and 9 patients (0.34%) died. Hospital admission rate and severity of ARI remain as important issues in hemodynamically significant congenital heart disease patients. The strict fulfillment of prophylactic recommendations against RSV is the only protective factor that can be modulated to decrease the ARI hospital admission rate.

Despite recent advances in understanding of the pathobiology and targeted treatments of pulmonary arterial hypertension (PAH), epidemiologic data from large populations have been limited to western countries. The aim of the Korean Registry of Pulmonary Arterial Hypertension (KORPAH) was to examine the epidemiology and prognosis of Korean patients with PAH. KORPAH was designed as a nationwide, multicenter, prospective data collection using an internet webserver from September 2008 to December 2011. A total of 625 patients were enrolled. The patients' mean age was 47.6 ± 15.7 yr, and 503 (80.5%) were women. The diagnostic methods included right heart catheterization (n = 249, 39.8%) and Doppler echocardiography (n = 376, 60.2%). The etiologies, in order of frequency, were connective tissue disease (CTD), congenital heart disease, and idiopathic PAH (IPAH) (49.8%, 25.4%, and 23.2%, respectively). Patients with WHO functional class III or IV at diagnosis were 43.4%. In total, 380 (60.8%) patients received a single PAH-specific treatment at the time of enrollment, but only 72 (18.9%) patients received combination therapy. Incident cases during the registry represented 297 patients; therefore, the incidence rate of PAH was 1.9 patients/yr/million people. The 1st-, 2nd-, and 3rd-yr estimated survival rates were 90.8%, 87.8%, and 84.4%, respectively. Although Korean PAH patients exhibited similar age, gender, and survival rate compared with western registries, they showed relatively more CTD-PAH in the etiology and also systemic lupus erythematosus among CTD-PAH. The data suggest that earlier diagnosis and more specialized therapies should be needed to improve the survival of PAH patients.

Etiologic profile and antimicrobial susceptibility of community-acquired urinary tract infection in two Cameroonian towns

PubMed Central

2012-01-01

Background Urinary tract infection (UTI) represents one of the most common diseases encountered in community medical practice. In resource poor settings, treatment is usually empiric due to the high cost and long duration required for reporting diagnosis by culture and antibiotic susceptibility testing. With the growing problem of drug resistance knowledge of antibiotic susceptibility pattern is pertinent for successful eradication of invading pathogens. Our study, the first of its kind in Cameroon, analyzed the distribution and antibiotic susceptibility of bacteria causing community-acquired urinary tract infection (CAUTI) in two towns (Bamenda and Buea) with a large number of young and middle aged persons, to provide data that could guide empiric treatment. Findings We cultured 235 urine specimens and analyzed the antibiotic susceptibility of isolates by the disc diffusion technique. Uropathogens were recovered from 137 (58.3%), with prevalence rates in Buea and Bamenda being 65.9% and 54% respectively. Predominant pathogens were Escherichia coli (31.4%), Klebsiella oxytoca (25.5%) and Staphylococcus spp (24.1%). Geographic variation in uropathogen distribution and antibiotic susceptibility was observed, and a significant difference in pathogen distribution with respect to gender. The 20–39 years age group had the highest prevalence of infection. All pathogens isolated were detected in this group. Isolates exhibited low susceptibility to antibiotics tested. Bamenda isolates generally exhibited lower susceptibility compared to those from Buea. Conclusion Regional variation in etiology of CAUTI and antibiotic susceptibility observed in our study emphasizes the need to establish local and national antimicrobial resistance monitoring systems in Cameroon to provide information for the development of CAUTI treatment guidelines.

Abnormal heart rate turbulence (HRT) has been documented as a strong predictor of total mortality and sudden death in postinfarction patients, but data in patients with congestive heart failure (CHF) are limited. The aim of this study was to evaluate the prognostic significance of HRT for predicting mortality in CHF patients in New York Heart Association (NYHA) class II-III. In 651 CHF patients with sinus rhythm enrolled into the MUSIC (Muerte Subita en Insuficiencia Cardiaca) study, the standard HRT parameters turbulence onset (TO) and slope (TS), as well as HRT categories, were assessed for predicting total mortality and sudden death. HRT was analyzable in 607 patients, mean age 63 years (434 male), 50% of ischemic etiology. During a median follow up of 44 months, 129 patients died, 52 from sudden death. Abnormal TS and HRT category 2 (HRT2) were independently associated with increased all-cause mortality (HR: 2.10, CI: 1.41 to 3.12, P <.001 and HR: 2.52, CI: 1.56 to 4.05, P <.001; respectively), sudden death (HR: 2.25, CI: 1.13 to 4.46, P = .021 for HRT2), and death due to heart failure progression (HR: 4.11, CI: 1.84 to 9.19, P <.001 for HRT2) after adjustment for clinical covariates in multivariate analysis. The prognostic value of TS for predicting total mortality was similar in various groups dichotomized by age, gender, NYHA class, left ventricular ejection fraction, and CHF etiology. TS was found to be predictive for total mortality only in patients with QRS > 120 ms. HRT is a potent risk predictor for both heart failure and arrhythmic death in patients with class II and III CHF.

Autism spectrum disorders (ASD) represent a common phenotype related to multiple etiologies, such as genetic, brain injury (e.g., prematurity), environmental (e.g., viral, toxic), multiple or unknown causes. To devise a clinical classification of children diagnosed with ASD according to etiologic workup. Children diagnosed with ASD (n = 436) from two databases were divided into groups of symptomatic cryptogenic or idiopathic, and variables within each database and diagnostic category were compared. By analyzing the two separate databases, 5.4% of the children were classified as symptomatic, 27% as cryptogenic and 67.75% as idiopathic. Among other findings, the entire symptomatic group demonstrated language delays, but almost none showed evidence for regression. Our results indicate similarities between the idiopathic and cryptogenic subgroups in most of the examined variables, and mutual differences from the symptomatic subgroup. The similarities between the first two subgroups support prior evidence that most perinatal factors and minor physical anomalies do not contribute to the development of core symptoms of autism. Differences in gender and clinical and diagnostic features were found when etiology was used to create subtypes of ASD. This classification could have heuristic importance in the search for an autism gene(s).

Endoscopic third ventriculostomy (ETV) has become the method of choice in the treatment of hydrocephalus. Age and etiology could determine success rates (SR) of ETV. The purpose of this study is to assess these factors in pediatric population. Retrospective study on 51 children with obstructive hydrocephalus that underwent ETV was performed. The patients were divided into three groups per their age at the time of the treatment: < 6, 6-24, and > 24 months of age. All ETV procedures were performed by the same neurosurgeon. Overall SR of ETV was 80% (40/51) for all etiologies and ages. In patients < 6 months of age SR was 56.2% (9/16), while 6-24 months of age was 88.9% (16/18) and > 24 months was 94.1% (16/17) (p = 0.012). The highest SR was obtained on aqueductal stenosis. SR of posthemorrhagic, postinfectious, and spina bifida related hydrocephalus was 60% (3/5), 50% (1/2), and 14.3% (1/7), respectively. While SR rate at the first ETV attempt was 85.3%, it was 76.9% in patients with V-P shunt performed previously (p = 0.000). Factors indicating a potential failure of ETV were young age and etiology such as spina bifida, other than isolated aqueductal stenosis. ETV is the method of choice even in patients with former shunting. Fast healing, distensible skulls, and lower pressure gradient in younger children, all can play a role in ETV failure. Based on our experience, ETV could be the first method of choice for hydrocephalus even in children younger than 6 months of age.

Sex, trauma, stress hormones and depression.

Although few studies dispute that there are gender differences in depression, the etiology is still unknown. In this review, we cover a number of proposed factors and the evidences for and against these factors that may account for gender differences in depression. These include the possible role of estrogens at puberty, differences in exposure to childhood trauma, differences in stress perception between men and women and the biological differences in stress response. None of these factors seem to explain gender differences in depression. Finally, we do know that when depressed, women show greater hypothalamic-pituitary-adrenal (HPA) axis activation than men and that menopause with loss of estrogens show the greatest HPA axis dysregulation. It may be the constantly changing steroid milieu that contributes to these phenomena and vulnerability to depression.

Uveitides can be due to non-infectious and infectious etiologies. It has been observed that there is a gender difference with a greater preponderance of non-infectious uveitis in women than in men. This review will describe both non-infectious and infectious uveitides and describes some of the current autoimmune mechanisms thought to be underlying the gender difference. It will specifically look at non-infectious uveitides with systemic involvement including juvenile idiopathic arthritis, spondyloarthopathies, sarcoidosis, Behçet’s disease, and Vogt-Koyanagi-Harada disease and at uveitides without systemic involvement including sympathetic ophthalmia, birdshot chorioretinitis, and the white dot syndromes. Infectious uveitides like acute retinal necrosis, progressive outer retinal necrosis, and cytomegalovirus mediated uveitis will be mentioned. Different uveitides with female- or male- predominance are presented and discussed. PMID:26035764

Background: Teacher-led oral health education is equally effective in improving the oral health knowledge and oral hygiene status of adolescents as dentist-led and peer-led strategies. Aim: The aim was to determine periodontal disease awareness and knowledge among Nigerian primary school teachers. Subjects and Methods: This cross-sectional study was conducted among primary school teachers in Edo State, Nigeria. A self-administered questionnaire which elicited information on demography, awareness of the periodontal disease and source of information, knowledge of etiology, and symptoms of the periodontal disease, was the data collection tool.. The test of association was done using either Chi-square or Fisher's exact statistics. P value was set at 0.05 for significance level. Results: Out of 180 teachers recruited from seven public primary schools in Benin City, Edo State, Nigeria, 151 of them fully participated by filling the study questionnaires giving a 83.9% (151/180) response rate. The majority 74.2% (112/151) of the participants reported having heard of the periodontal disease and the leading source of information was television. A total of 29.8% (45/151) of participants considered periodontal disease as the main cause of tooth loss among adult Nigerian. Only 12.6% (19/151) of the participants knew dental plaque as soft debris on teeth and 29.1% (44/151) attested that plaque can cause periodontal disease. The majority of the participants were not aware of age 81.5% (123/151) and gender 96.7% (146/151) predisposition to periodontal disease. The perceived manifestations of the periodontal disease reported by were mainly gum bleeding 35.1% (53/151) and swollen gum 20.5% (31/151). A total of 70.2% (106/151) of the participants considered periodontal disease as a preventable disease and about half 49.0% (74/151) of the participants considered daily mouth cleaning as the best preventive method. The majority 95.4% (144/151) of the participants expressed interest in learning about the periodontal disease and the most preferred methods were workshops and lectures. Conclusion: A significant proportion of the participants heard about periodontal disease from nondental clinic sources. There existed a poor awareness of etiology, age and gender predispositions, manifestation, complications, and the preventable nature of periodontal disease among the participants. However, the majority of them indicated interest in learning about periodontal disease which should be utilized in optimizing their knowledge. PMID:26500791

The rise of eating disorders in Japan: issues of culture and limitations of the model of "westernization".

As the first non-Western nation in contemporary history to become a major industrialized economic power, Japan is central to the debate on cultural relativism in psychiatric nosologies, and the study of eating disorders in Japan contributes to the complex discussion of the impact of culture and history on the experience, diagnosis and treatment of such disorders (R. Gordon 2001; Palmer 2001). Without question, the rise in eating disorders in Japan correlated with increasing industrialization, urbanization, and the fraying of traditional family forms following World War II. While the case of Japan confirms that the existence of eating disorders appears to be linked with these broader social transformations, it also points to the importance of specific cultural and historical factors in shaping the experience of eating disorders. In this article, we explore two particular dimensions of culture in contemporary Japan: (1) gender development and gender role expectations for females coming of age; and (2) beauty ideals and the role of weight and shape concerns in the etiology of eating disorders. Our analysis of these dimensions of culture, and the data accruing from empirical and qualitative research, reveal limitations to the model of "Westernization" and call for a more culturally sensitive search for meaning in both describing and explaining eating disorders in Japan today.

To investigate the causes of non-hemolytic jaundice among infants in Chongqing, China from the period of 1982 to 2011 and to determine whether the etiologies have changed over the past 30 years. The medical records of 3 113 infants,aged 1 month to 1 year,admitted to our hospital with non-hemolytic jaundice were collected and stratified according to decade-long time periods: group A (1982-1991), n=537; group B (1992-2001), n=786; group C (2002-2011), n=1 790. Data on sex, age, etiology and bilirubin level were retrospectively assessed using the chi-square test. In the three groups, boys consistently accounted for the majority of cases (group A:74.3%, group B:66.7%, group C:62.6%). In group A, 52% of the patients were 1-2 months of age; the peak age of patients in both group B and C was 2-3 months (group B:67.8%, group C:61.0%). Group A showed the highest level of patients with mildly elevated total bilirubin level (80.3%); however, moderately elevated total bilirubin level was most frequent in group B (53.4%) and group C (49.7%). The main etiologic diagnoses of the patients in group A were cytomegalovirus (CMV) infection (31.7%), sepsis (18.2%), hepatitis B virus (HBV) (1.3%), and biliary tract anomalies (1.3%); 46.6% of the cases had unclear cause. The main etiologic diagnoses of the cases in group B were CMV infection (36.0%), sepsis (21.5%), breast milk jaundice (2.0%), and HBV (1.9%); 37.9% of the cases had unclear cause. The main etiologic diagnoses of the cases in group C were CMV infection (42.6%), sepsis (7.5%), breast milk jaundice (17.7%), and biliary tract anomalies (2.46%); 29.1% of the cases had unclear cause. In Chongqing, infective factors, especially CMV, remain the main cause of nonhemolytic jaundice in infants, but bacterial etiologies have declined over the past 30 years.Non-infective factors, such as biliary tract anomalies and inherited metabolic diseases, have trended upwards. Although there has been great progress in the clinical management of non-hemolytic jaundice in infants, etiological diagnosis remains a challenge and further study is needed to eliminate this condition.

Historical variation in young adult binge drinking trajectories and its link to historical variation in social roles and minimum legal drinking age

Jager, Justin; Keyes, Katherine M.; Schulenberg, John E.

2015-01-01

This study examines historical variation in age 18–26 binge drinking trajectories, focusing on differences in both level of use and rates of change (growth) across cohorts of young adults over three decades. As part of the national Monitoring the Future Study, over 64,000 youths from the high school classes of 1976–2004 were surveyed at biennial intervals between ages 18 and 26. We found that, relative to past cohorts, recent cohorts both enter the age 18–26 age band engaging in lower levels and exit the age 18–26 age band engaging in higher levels of binge drinking. The reason for this reversal is that, relative to past cohorts, binge drinking among recent cohorts accelerates more quickly across ages 18–22 and decelerates more slowly across ages 22–26. Moreover, we found that historical increases in minimum legal drinking age account for a portion of the historical decline in age 18 level, while historical variation in social role acquisition (e.g., marriage, parenthood, and employment) accounts for a portion of the historical acceleration in age 18–22 growth. We also found that historical variation in the age 18–22 and age 22–26 growth rates was strongly and positively connected, suggesting common mechanism(s) underlie historical variation of both growth rates. Findings were generally consistent across gender and indicate that historical time is an important source of individual differences in young adult binge drinking trajectories. Beyond binge drinking, historical time may also inform the developmental course of other young adult risk behaviors, highlighting the interplay of epidemiology and etiology. PMID:26010381

A multi-level analysis of the effects of age and gender stereotypes on trust in anthropomorphic technology by younger and older adults.

Previous research has shown that gender stereotypes, elicited by the appearance of the anthropomorphic technology, can alter perceptions of system reliability. The current study examined whether stereotypes about the perceived age and gender of anthropomorphic technology interacted with reliability to affect trust in such technology. Participants included a cross-section of younger and older adults. Through a factorial survey, participants responded to health-related vignettes containing anthropomorphic technology with a specific age, gender, and level of past reliability by rating their trust in the system. Trust in the technology was affected by the age and gender of the user as well as its appearance and reliability. Perceptions of anthropomorphic technology can be affected by pre-existing stereotypes about the capability of a specific age or gender. The perceived age and gender of automation can alter perceptions of the anthropomorphic technology such as trust. Thus, designers of automation should design anthropomorphic interfaces with an awareness that the perceived age and gender will interact with the user’s age and gender

Pediatric gender identity has gained increased attention over the past several years in the popular media, political arena, and medical literature. This article reviews terminology in this evolving field, traditional models of gender identity development and their limitations, epidemiology and natural history of cross-gender identification among children and adolescents, co-occurring conditions and behaviors, research into the biological and psychosocial determinants of cross-gender identification, and research into the options regarding and benefits of clinical approaches to gender incongruent youth. Based on a critical review of the extant literature, both theoretical and empirical, that addresses the issue of pediatric gender identity, the authors synthesized what is presently known and what is in need of further research in order to elucidate the developmental trajectory and clinical needs of gender diverse youth. The field of pediatric gender identity has evolved substantially over the past several years. New research suggests that cross-gender identification is prevalent (approximately 1% of youth). These youth suffer disproportionately high rates of anxiety, depression, and suicidality. Although research into the etiology of cross-gender identification is limited, emerging data have shown that affirmative treatment protocols may improve the high rates of mental health difficulties seen among these patients. The field of pediatric gender identity has evolved dramatically. Emerging data suggest that these patients' high rates of anxiety, depression, and suicidality appear to be improved with affirmative protocols, although future longitudinal data are needed. © 2017 Association for Child and Adolescent Mental Health.

Graves' disease (GD) is an autoimmune thyroid disease with complex and not fully established etiology. It occurs when environmental factors influence people genetically prone to this illness. The aim of this study was to determine the impact of selected factors (endogenous and environmental) on the course and complications of disease in patients with recurrent GD. Two hundred and four patients with relapsed GD, treated in the Clinical Department of Endocrinology in University Hospital in Cracow in years 2004-2006 and then in 2011 were retrospectively analyzed. Patients who agreed to participate in the study were sent questionnaire to complete. Demographic and clinical data were collected and entered into a database. Patient data included: gender, place of living, lifestyle (smoking), family history of autoimmune diseases, the course of the disease, its symptoms and the treatment strategy. Furthermore the medical documentation was analyzed. Descriptive statistical analyses were made. The study showed a significant difference in the frequency of appearance of ophthalmopathy between men and women (80% and 37.14%, respectively, p = 0.041), between smokers and nonsmokers (61.9% and 21.05%, respectively, p = 0.022) and between the age of patients with positive and negative family history of autoimmune diseases (37.6 years and 50.5 years respectively, p = 0.002). 1. Male gender is a risk factor for ophthalmopathy in GD. 2. Cigarette smoking affects the risk of Graves' ophthalmopathy. 3. A positive family history of thyroid diseases and/or autoimmune diseases promotes the development of GD at a younger age.

Bruxism is the habit of clenching or grinding one's teeth in non-functional activities and affects both children and adults alike. Respiratory problems, such as asthma and upper airway infections, are reported to be the etiological factors of bruxism. The aim of the present study was to determine whether there is an association between respiratory problems and dental caries in children who exhibit the habit of bruxism. An observational cross-sectional study was carried out. Patient histories were taken and clinical exams were performed on 90 children for selection and allocation to one of two groups. For the determination of bruxism, a questionnaire was administered to parents/guardians and an oral clinical exam was performed based on the criteria of the American Academy of Sleep Medicine. Thirty-three male and female children between 4 and 7 years of age participated in the study - 14 children with bruxism and 19 children without bruxism. The data were statistically analyzed using the chi-square test, with level of significance set at 5% (P < 0.05). Mean age of the participants was 5.73 years. The male gender accounted for 45.5% (n = 15) of the sample and the female gender accounted for 54.5% (n = 18). A statistically significant association was found between respiratory problems and dental caries among the children with bruxism. Seventy-seven percent of the children with bruxism had caries and 62.5% the children with respiratory problems exhibited the habit of bruxism. There seems to be an association between bruxism, respiratory problems, and dental caries in children.

Purpose Inadequate physical activity and obesity during adolescence are areas of public health concern. Questions exist about the role of neighborhoods in the etiology of these problems. This research addressed the relationships of perceived and objective reports of neighborhood crime to adolescent physical activity, screen media use, and BMI. Methods Socioeconomically and racially/ethnically diverse adolescents (N=2,455, 53.4% female) from 20 urban, public middle and high schools in Minneapolis/St. Paul, Minnesota responded to a classroom survey in the EAT 2010 (Eating and Activity in Teens) study. Body mass index (BMI) was measured by research staff. Participants’ mean age was 14.6 (SD=2.0); 82.7% represented racial/ethnic groups other than non-Hispanic white. Linear regressions examined associations between crime perceived by adolescents and crime reported to police and the outcomes of interest (BMI z-scores, physical activity, and screen time). Models were stratified by gender and adjusted for age, race/ethnicity, socioeconomic status, and school. Results BMI was positively associated with perceived crime among girls and boys and with reported crime in girls. For girls, there was an association between higher perceived crime and increased screen time; for boys, between higher reported property crime and reduced physical activity. Perceived crime was associated with reported crime, both property and personal, in both genders. Conclusions Few prior studies of adolescents have studied the association between both perceived and reported crime and BMI. Community-based programs for youth should consider addressing adolescents’ safety concerns along with other perceived barriers to physical activity. Interventions targeting actual crime rates are also important. PMID:26206444

Association of social and cognitive impairment and biomarkers in autism spectrum disorders

2014-01-01

Objectives The neurological basis for autism is still not fully understood, and the role of the interaction between neuro-inflammation and neurotransmission impairment needs to be clearer. This study aims to test the possible association between impaired levels of gamma aminobutyric acid (GABA), serotonin, dopamine, oxytocin, and interferon-γ-induced protein-16 (IFI16) and the severity of social and cognitive dysfunctions in individuals with autism spectrum disorders. Materials and methods GABA, serotonin, dopamine, oxytocin, and IFI16 as biochemical parameters related to neurochemistry and inflammation were determined in the plasma of 52 Saudi autistic male patients, categorized as mild-moderate and severe as indicated by their Childhood Autism Rating Scale (CARS) or social responsiveness scale (SRS), and compared to 30 age- and gender-matched control samples. Results The data indicated that Saudi patients with autism have remarkably impaired plasma levels of the measured parameters compared to age and gender-matched controls. While serotonin in platelet-free plasma and dopamine did not correlated with the severity in social and cognitive dysfunction, GABA, oxytocin, and IFI16 were remarkably associated with the severity of both tested scores (SRS and CARS). Conclusions The relationship between the selected parameters confirms the role of impaired neurochemistry and neuro-inflammation in the etiology of autism spectrum disorders and the possibility of using GABA, oxytocin, and IFI16 as markers of autism severity. Receiver operating characteristic analysis together with predictiveness diagrams proved that the measured parameters could be used as predictive biomarkers of clinical symptoms and provide significant guidance for future therapeutic strategy to re-establish physiological homeostasis.

Family disruption increases functional somatic symptoms in late adolescence: the TRAILS study.

van Gils, Anne; Janssens, Karin A M; Rosmalen, Judith G M

2014-11-01

Functional somatic symptoms (FSSs) are physical symptoms that cannot be (fully) explained by organic pathology. FSSs are very common among children and adolescents, yet their etiology is largely unknown. We hypothesize that (a) the experience of family disruption due to parental divorce or parental death increases FSSs in adolescents; (b) symptoms of depression and anxiety contribute to the relationship between family disruption and FSSs; (c) girls are more vulnerable to these effects than boys. Data were obtained from the prospective population cohort of Dutch adolescents of the Tracking Adolescents' Individual Lives Survey (N = 2,230), aged 10 to 12 years at baseline. FSSs were assessed using the Somatic Complaints subscale of the Youth Self-Report. Parental divorce and parental death were assessed with self-reports. Both outcome and predictors were assessed during 3 assessment waves over the course of 5 years. Linear mixed models were used to investigate associations between both types of family disruption and FSSs. An interaction with age was found for parental divorce (B = 0.01, p = .02) and parental death (B = 0.03, p = .04), indicating that the influence of family disruption on FSSs increases during adolescence. This relationship seems to be partly explained by symptoms of depression and anxiety. No gender differences were found with regard to the effects of family disruption on FSSs. Family disruption is associated with an increased level of FSSs in late adolescence in both genders. This relationship is partly explained by symptoms of depression and/or anxiety.

This study explores the association between private and public body consciousness and past 30-day cigarette, alcohol, marijuana, and hard drug use among adolescents. Self-reported data from alterative high school students in California were analyzed (N = 976) using multilevel regression models to account for student clustering within schools. Separate regression analyses were conducted for males and females. Both cross-sectional baseline data and one-year longitudinal prediction models indicated that body consciousness is associated with specific drug use categories differentially by gender. Findings suggest that body consciousness accounts for additional variance in substance use etiology not explained by previously recognized dispositional variables.

Age-related macular degeneration is the leading cause of blindness in elderly individuals in developed countries. The etiology and pathophysiology of age-related macular degeneration have not been elucidated yet. Knowing that the main pathological change of age-related macular degeneration is formation of drusen containing about 40% of lipids, there have been attempts to find associations between age-related macular degeneration and genes controlling lipid metabolism. To determine the frequency of CYP2C19 (G681A) Rs4244285 and CYP1A2 (-163C>A) Rs762551 genotypes in patients with age-related macular degeneration. The study enrolled 150 patients with early age-related macular degeneration and 296 age- and gender-matched healthy controls. The genotyping of Rs4244285 and Rs762551 was carried out by using the real-time polymerase chain reaction method. The CYP1A2 (-163C>A) Rs762551 C/C genotype was more frequently detected in patients with age-related macular degeneration than in the control group (32.7% vs. 21.6%, p = 0.011) and was associated with an increased risk of developing early age-related macular degeneration (OR = 1.759, 95% CI: 1.133-2.729; p = 0.012). The CYP1A2 (-163C>A) Rs762551 C/A genotype was more frequently documented in the control group compared with patients with age-related macular degeneration (46.3% vs. 30.7%, p = 0.002) and was associated with a decreased risk of having age-related macular degeneration (OR = 0.580. 95% CI: 0.362-0.929, p = 0.023) in the co-dominant model. The study showed that the CYP1A2 (-163C>A) Rs762551 C/C genotype was associated with an increased risk of age-related macular degeneration.

The study involved 138 patients (186 ears) of either sex at the age from 1 year to 84 months who presented with acute suppurative otitis media. The following methods were employed for the purpose of the study: analysis of the patients' complaints and the past medical histories, examination of the ENT organs, microbiological (bacteriological and virological) studies of secretion from the tympanic cavity, diagnostic endoscopy of the nasal cavity and nasopharynx, laboratory investigations. The study allowed to reveal the characteristic clinical manifestations of the pathology of interest depending on its etiology.

Objective To determine the prevalence, etiologies, and risk factors of blindness and visual impairment among persons age 40 years and older residing in an urban West African location. Design Population-based cross-sectional study. Participants Five thousand six hundred and three participants residing in Tema, Ghana. Methods Proportionate random cluster sampling was used to select participants age 40 and over living in the city of Tema. Presenting distance visual acuity was measured at 4 and 1 meters using a reduced Logarithm of the Minimum Angle of Resolution (logMAR) tumbling E chart and then with trial frame based on autorefraction. A screening examination was performed in the field on all participants. Complete clinical examination by an ophthalmologist was performed on participants with best corrected visual acuity < 20/40 or failure of any screening test. Main Outcome Measures Age- and gender-specific prevalence, causes, and risk factors for blindness (visual acuity in the better eye of < 20/400, World Health Organization definition) and visual impairment (visual acuity in the better eye of < 20/40). Results Six thousand eight hundred and six eligible participants were identified of which 5603 (82.3%) participated in the study. The mean age (±standard deviation) of participants was 52.7±10.9. The prevalence of visual impairment was 17.1% and blindness was 1.2%. After refraction and spectacle correction, the prevalence of visual impairment and blindness decreased to 6.7% and 0.75% respectively, suggesting that refractive error is the major correctable etiology of visual impairment and blindness in this population. Of 65 subjects having visual acuity < 20/400, 22 (34%) were correctable with refraction, 21 to the level of visual impairment, and one to normal. The remaining 43 (66%) had underlying pathology (19 cataract, 9 glaucoma, 3 non-glaucomatous optic neuropathy, 3 corneal opacities, 3 retinal disease, 5 undetermined) that prevented refractive correction. Increased age was a significant risk factor for blindness and visual impairment. Conclusions There is a high prevalence of blindness and visual impairment among those aged ≥40 years in Tema, Ghana, West Africa. Refractive error is a major cause of blindness and visual impairment in this population, followed by cataract, glaucoma, and corneal disease. PMID:22677425

[About the heterogeneity in adolescents with gender identity disorder: differential importance of psychiatric comorbidity and considerations of individual psychodynamics].

Gender identity disorder (GID), gender dysphoria (GD) respectively, is considered a multifactorial disease whose etiology is subject to complex bio-psycho-social conditions, each with different weighting. As a result, therapists, who treat children and adolescents with GID/GD, have to deal with a very heterogeneous group with individually varying causes, differing psychopathology and varying disease progression. In addition to general psychiatric aspects of development, particularly psychiatric comorbidity, but also the different individual psychodynamics--i. e. the specific constellation of conflicts and possible ego deficits and structural deficits in the learning history of the person are of differential importance. In regard to the indication for gender reassignment measures this sometimes is relevant for the decision. The difficulties arising for decision making and the usefulness of a systematic evaluation of case reports as a basis for further optimization of the treatment recommendations are illustrated by two case reports. In the course of this, also the disadvantages and potential dangers of too early diagnostic definition and introduction of gender somato-medical and legal measures are shown exemplarily.

We report whether the etiology underlying associations of childhood ADHD with adolescent alcohol and marijuana involvement is consistent with causal relationships or shared predispositions, and whether it differs by gender. In three population-based twin samples (N = 3762; 64% monozygotic), including one oversampling females with ADHD, regressions were conducted with childhood inattentive or hyperactive-impulsive symptoms predicting alcohol and marijuana outcomes by age 17. To determine whether ADHD effects were consistent with causality, twin difference analyses divided effects into those shared between twins in the pair and those differing within pairs. Adolescents with more severe childhood ADHD were more likely to initiate alcohol and marijuana use earlier, escalate to frequent or heavy use, and develop symptoms. While risks were similar across genders, females with more hyperactivity-impulsivity had higher alcohol consumption and progressed further toward daily marijuana use than did males. Monozygotic twins with more severe ADHD than their co-twins did not differ significantly on alcohol or marijuana outcomes, however, suggesting a non-causal relationship. When co-occurring use of other substances and conduct/oppositional defiant disorders were considered, hyperactivity-impulsivity remained significantly associated with both substances, as did inattention with marijuana, but not alcohol. Childhood ADHD predicts when alcohol and marijuana use are initiated and how quickly use escalates. Shared familial environment and genetics, rather than causal influences, primarily account for these associations. Stronger relationships between hyperactivity-impulsivity and heavy drinking/frequent marijuana use among adolescent females than males, as well as the greater salience of inattention for marijuana, merit further investigation.

Evidence suggests that education protects from dementia by enhancing cognitive reserve. However, this may be influenced by several socio-demographic factors. Rising numbers of dementia in India, high levels of illiteracy and heterogeneity in socio-demographic factors provide an opportunity to explore this relationship. To study the association between education and age at dementia onset, in relation to socio-demographic factors. Association between age at dementia onset and literacy was studied in relationship to potential confounding factors such as gender, bilingualism, place of dwelling, occupation, vascular risk factors, stroke, family history of dementia and dementia subtypes. Case records of 648 dementia patients diagnosed in a specialist clinic in a University hospital in Hyderabad, India were examined. All patients were prospectively enrolled as part of an ongoing longitudinal project that aims to evaluate dementia subjects with detailed clinical, etiological, imaging, and follow-up studies. Of the 648 patients, 98 (15.1%) were illiterate. More than half of illiterate skilled workers were engaged in crafts and skilled agriculture unlike literates who were in trade or clerical jobs. Mean age at onset in illiterates was 60.1 years and in literates 64.5 years (p=0.0002). Factors independently associated with age at dementia onset were bilingualism, rural dwelling and stroke, but not education. Our study demonstrates that in India, rural dwelling, bilingualism, stroke and occupation modify the relationship between education and dementia.

PURPOSE: Angle-closure glaucoma is rare in children and young adults. Only scattered cases associated with specific clinical entities have been reported. We evaluated the findings in patients in our database aged 40 or younger with angle closure. METHODS: Our database was searched for patients with angle closure who were 40 years old or younger. Data recorded included age at initial consultation; age at the time of diagnosis; gender; results of slit-lamp examination, gonioscopy, and ultrasound biomicroscopy (from 1993 onward); clinical diagnosis; and therapy. Patients with previous incisional surgery were excluded, as were patients with anterior chamber proliferative mechanisms leading to angle closure. RESULTS: Sixty-seven patients (49 females, 18 males) met entry criteria. Mean age (+/- SD) at the time of consultation was 34.4 +/- 9.4 years (range, 3-68 years). Diagnoses included plateau iris syndrome (35 patients), iridociliary cysts (8 patients), retinopathy of prematurity (7 patients), uveitis (5 patients), isolated nanophthalmos (3 patients), relative pupillary block (2 patients), Weill-Marchesani syndrome (3 patients), and 1 patient each with Marfan syndrome, miotic-induced angle closure, persistent hyperplastic primary vitreous, and idiopathic lens subluxation. CONCLUSION: The etiology of angle closure in young persons is different from that in the older population and is typically associated with structural or developmental ocular anomalies rather than relative pupillary block. Following laser iridotomy, these eyes should be monitored for recurrent angle closure and the need for additional laser or incisional surgical intervention. PMID:12545694

Prader-Willi syndrome (PWS) is a genetically determined neurodevelopmental disorder characterized by mental retardation and distinct physical, behavioral, and psychiatric features. Based on parents' questionnaires, we examined the prevalence of behavioral and psychiatric disorders of 165 persons with PWS aged 2-31 years in Japan. The data were analyzed comparing four different age groups with PWS: group 1, 2-5 years (n=34); group 2, 6-11 years (n=57); group 3, 12-17 years (n=45); and group 4, 18-31 years (n=29). Further, we compared the results of our PWS group 4 with those of 42 age-, gender-, and intelligence level-matched intellectual disability (ID) individuals without PWS. Our results showed that repetitive speech and stubbornness were prominent from early childhood and other behavioral problems such as hyperphagia, stealing food, temper tantrums, lying, and emotional lability tended to be more frequent with age among persons with PWS. Moreover, young adults with PWS have significantly higher rates of behavioral and psychiatric disorders than IDs without PWS, such as stubbornness, hyperphagia, temper tantrums, self-injurious behavior (skin picking), hypersomnia, inactivity, and delusion. Degree of obesity was not necessarily related to behavioral and psychiatric features associated with PWS. Our findings revealed that persons with PWS are more vulnerable to behavioral and psychiatric disorders particularly in young adulthood compared to those with ID from other etiologies in Japan.

A cross-sectional design across late childhood and adolescence examined the influence of sex, gender socialization, and age on responses to controlled laboratory pain tasks. Healthy children and adolescents (n = 240, 50% female, age 8 to 18 years) completed the Child Sex Role Inventory, a self-report measure of identification with stereotypically masculine and feminine personality traits, as an index of gender socialization and participated in pressure, cold pressor, and heat pain tasks. Pain tolerance, pain intensity, and bothersomeness of each pain task were assessed. Masculinity correlated with lower heat pain ratings in boys but not girls. Logistic regression indicated cold pain intensity ratings were predicted by sex, gender score, and the age-by-gender score interaction. Heat pain intensity was predicted by age, gender score, age-by-gender score interaction, and sex-by-gender score. The current findings support closer examination of the influence of gender socialization on young people's pain responses and highlight the importance of a multifactorial, developmental approach to studying the impact of gender socialization on the emergence of sex differences in pain responses after puberty.

Background: The objective of this study was to identify the prognostic factors that influence the outcome of ovarian stimulation with intrauterine insemination (IUI) cycles in couples with different infertility etiology. Materials and Methods: This retrospective study was performed in data of 1348 IUI cycles with ovarian stimulation by clomiphene citrate (CC) and/or gonadotropins in 632 women with five different infertility etiology subgroups at Akbarabbadi Hospital, Tehran, Iran. Results: The pregnancy rate (PR)/ cycle was highest (19.9%) among couples with unexplained infertility and lowest (10.6%) in couples with multiple factors infertility. In cases of unexplained infertility, the best PRs were seen after CC plus gonadotropins stimulation (26.3%) and with inseminated motile sperm count>30×106 (21.9%), but the tendency didn’t reach statistical significant. In the ovarian factor group, the best PRs were observed in women aged between 30 and 34 years (20.8%), with 2-3 preovulatory follicles (37.8%) and infertility duration between 1and 3 years (20.8%), while only infertility duration (p=0.03) and number of preovulatory follicles (p=0.01) were statistically significant. Multiple logistic regression analysis determined that number of preovulatory follicles (p=0.02), duration of infertility (p=0.015), age (p=0.019), infertility etiology (p=0.05) and stimulation regimen (p=0.01) were significant independent factors in order to predict overall clinical PR. Conclusion: The etiology of infertility is important to achieve remarkable IUI success. It is worth mentioning that within different etiologies of infertility, the demographic and cycles characteristics of couples did not show the same effect. Favorable variables for treatment success are as follows: age <40, duration of infertility ≤5 years and a cause of infertility except of multiple factors. PMID:24520471

Strokes in pediatric age group are not common. However diagnosing the cause of stroke will help in providing preventive and curative treatment. Present study was conducted to find etiology of strokes/hemiplegia in children. This study was conducted in Department of Pediatrics, Ayub Teaching Hospital Abbottabad from December 2002 to December 2005. All children from two months to fifteen years of age were included in the study. Children with weakness due to acute poliomyelitis and Guillan barre syndrome were excluded. Investigations were based on findings on history and clinical examination and included full blood count, PT, APTT, Platelets count, ECG, Echocardiography, hematocrit, lumber puncture with CSF analysis and culture and CT-scan skull. Data of all the patients presenting with strokes/hemiplegia was entered on prepared proforma. The main etiology of strokes was intracranial infection causing strokes in 23(56.09%)children and majority of children (78.26%) in this group were below five years. Etiology was un-known in 7(17.07%) children after necessary available investigations. Intracranial infection Infections that is meningitis and encephalitis are commonest etiology of strokes and hemiplegia in paediatrics patients presenting at Ayub Teaching Hospital, Abbottabad.

This study examined factors that predicted children’s gender intergroup attitudes at age 5 and the implications of these attitudes for intergroup behavior. Ethnically-diverse children from low-income backgrounds (N=246, Mexican-, Chinese-, Dominican-, and African-American) were assessed at ages 4 and 5. On average, children reported positive same-gender and negative other-gender attitudes. Positive same-gender attitudes were associated with knowledge of gender stereotypes. In contrast, positive other-gender attitudes were associated with flexibility in gender cognitions (stereotype flexibility, gender consistency). Other-gender attitudes predicted gender-biased behavior. These patterns were observed in all ethnic groups. These findings suggest that early learning about gender categories shape young children’s gender attitudes, and that these gender attitudes already have consequences for children’s intergroup behavior at age 5.

Sex refers to biological differences between men and women. Although sex is a fundamental aspect of human physiology that splits the population in two approximately equal halves, this essential biological variable is rarely considered in the design of basic physiological studies, in translating findings from basic science to clinical research, or in developing personalized medical strategies. Contrary to sex, gender refers to social and cultural factors related to being a man or a woman in a particular historical and cultural context. Unfortunately, gender is often used incorrectly by scientists and clinical investigators as synonymous with sex. This article clarifies the definition of sex and gender and reviews evidence showing how sex and gender interact with each other to influence etiology, presentation of disease, and treatment outcomes. In addition, strategies to improve the inclusion of female and male human beings in preclinical and clinical studies will be presented, and the importance of embedding concepts of sex and gender into postgraduate and medical curricula will be discussed. Also, provided is a list of resources for educators. In the history of medical concepts, physiologists have provided pivotal contributions to understanding health and disease processes. In the future, physiologists should provide the evidence for advancing personalized medicine and for reducing sex and gender disparities in health care.

Gender Differences in Cancer Susceptibility: An Inadequately Addressed Issue

PubMed Central

Dorak, M. Tevfik; Karpuzoglu, Ebru

2012-01-01

The gender difference in cancer susceptibility is one of the most consistent findings in cancer epidemiology. Hematologic malignancies are generally more common in males and this can be generalized to most other cancers. Similar gender differences in non-malignant diseases including autoimmunity, are attributed to hormonal or behavioral differences. Even in early childhood, however, where these differences would not apply, there are differences in cancer incidence between males and females. In childhood, few cancers are more common in females, but overall, males have higher susceptibility. In Hodgkin lymphoma, the gender ratio reverses toward adolescence. The pattern that autoimmune disorders are more common in females, but cancer and infections in males suggests that the known differences in immunity may be responsible for this dichotomy. Besides immune surveillance, genome surveillance mechanisms also differ in efficiency between males and females. Other obvious differences include hormonal ones and the number of X chromosomes. Some of the differences may even originate from exposures during prenatal development. This review will summarize well-documented examples of gender effect in cancer susceptibility, discuss methodological issues in exploration of gender differences, and present documented or speculated mechanisms. The gender differential in susceptibility can give important clues for the etiology of cancers and should be examined in all genetic and non-genetic association studies. PMID:23226157

Objective A prospective study was designed to analyze risk factors and clinical features in children with global developmental delay (GDD) at our hospital. No previous data is available on GDD from Oman. Methods This study was conducted at Sultan Qaboos University Hospital from January 2008 until June 2009. All the children aged 5 years or less, referred with suspected GDD were included in the study. Data was analyzed to determine the underlying etiology. The children with neurodegenerative disease and muscular dystrophy were excluded from the study. Results One hundred and ten children, 59 males (53.6%) and 51 females (46.4%) were included in the study. The mean age at initial evaluation was 13.29 months. An underlying etiology was determined in 79 (71.8%) children. Perinatal history was associated with significant difference in detection of etiology (p=0.039). Abnormal neurological examination was a significant factor in detection of the underlying etiology. Magnetic resonance imaging (MRI) in 105 children and metabolic screening in 93 children were the most frequently ordered investigations. Abnormal imaging, MRI (p=0.001), CT scan (p=0.036) and metabolic screening (p=0.034) were significantly associated with detection of etiology. Conclusion Etiology was detected in 71.8% of the children. MRI was the most significant investigation to detect the abnormality. PMID:23071884

Although ethnic or cultural differences affect prevalence of cardiovascular risk factors, limited information is available about the age- and gender-stratified prevalence of the risk factors in Asian stroke population. We assessed gender- and age-stratified prevalences of major risk factors in Korean stroke patients, and assumed that the gender differences are attenuated by adjustment with lifestyle factors. Using the nationwide hospital-based stroke registry, we identified 9417 ischemic stroke patients admitted between April 2008 and January 2011. Prevalence of hypertension, diabetes, hyperlipidemia, atrial fibrillation, prior stroke, and coronary heart disease was assessed in both genders by age groups. We analyzed gender differences of the prevalence among the age groups by calculating prevalence ratio, and further explored the influence of lifestyle factors on the gender difference in multivariable analyses. Hypertension and hyperlipidemia were more common in men until middle age, but after that more common in women, whereas diabetes was more common in women after 65 years of age. Atrial fibrillation increased steadily with age in both genders but was more common in women through all age groups. Prior stroke and coronary heart disease showed inconsistent gender differences. Gender differences in hypertension and diabetes among the age groups were attenuated by adjustment with accompanying risk factors including lifestyle factors. Korean women with stroke had more hypertension and hyperlipidemia after middle age, more diabetes after 65 years, and more atrial fibrillation throughout all ages. Strategies to control risk factors in women at risk for stroke are eagerly needed. © 2013 The Authors. International Journal of Stroke © 2013 World Stroke Organization.

Population-based studies on infantile epilepsy syndromes are scarce. Our aim was to provide syndrome-specific data on the incidence and outcome of epilepsy in a population-based cohort of infants with epilepsy onset in the first year. Included were all infants born in 1997 through 2006 whose epileptic seizures started before 12 months of age and who were residents of the Helsinki University Hospital district at the time of seizure onset. Patients were ascertained from hospital statistics, and all patient charts were reviewed. A reevaluation of the epilepsy syndromes, age at onset, etiology, and outcome at 24 months of age was based on data abstracted from the patient files. Inclusion criteria were fulfilled by 158 infants, of whom 92% were followed until age 24 months or death. The incidence of epilepsy in the first year was 124 of 100,000. An epilepsy syndrome recognized by the revised organization of epilepsies by ILAE was identified in 58% of the patients. The most common syndromes were West syndrome (41/100,000) and benign familial or nonfamilial infantile epilepsy (22/100,000). Etiology was structural-metabolic in 35%, genetic in 17%, and unknown in 48%. Early age at onset was associated with structural-metabolic etiology. Seven infants (4.4%) died before age 2 years. One infant with an SCN2A mutation died of sudden unexplained death in epilepsy (SUDEP). At 24 months, 58% of all children included in the cohort were seizure-free, and 46% had both seizure freedom and age-appropriate cognitive development. Age at onset was not associated with outcome when etiology was controlled for. Benign familial and nonfamilial infantile epilepsy appears to be more common than previously suggested, second only to West syndrome. Early age at onset is not an independent risk factor for poor outcome. Wiley Periodicals, Inc. © 2016 International League Against Epilepsy.

The objective of this study was to compare liver transplantation outcomes as a function of donor age. We performed 212 liver transplantations between 2008 and 2014. We described a prospective cohort study and grouped the patients by liver donor age. We compared quantitative and categorical variables using statistical analysis. No statistically significant differences were found among any graft age groups in gender (always more males), time on waiting list, age, height, Child Pugh Turcotte (CHILD) score, Model for End-stage Liver Disease (MELD) score, need for intraoperative blood products, or intensive care unit stay. The most frequent etiology of liver failure was alcohol. A brain-dead donor was the most frequent type in all groups. The whole graft was used except in 4 cases. No statistically significant differences were found among groups in the surgical technique, postreperfusion syndrome, arterial complications, biliary complications, venous complications, acute rejection, and retransplantation. The 3-year patient survival rate was 64% in the <60-year graft age group, 48% in the 60- to 69-year group, 64% in the 70- to 79-year group, and 40% in the ≥80-year group (P = .264). The 3-year graft survival rate was 62% in the <60-year graft age group, 47% in the 60- to 69-year group, 65% in the 70- to 79-year group, and 40% in the ≥80-year group (P = .295). Given the need to increase the pool of liver donors, older donors should be considered as a source for liver transplantation, although careful selection is required. Copyright © 2016 Elsevier Inc.

A new modular, outcome-based, interdisciplinary curriculum was introduced for undergraduate medical education at one of the largest European medical faculties. A key stated institutional goal was to systematically integrate sex and gender medicine and gender perspectives into the curriculum in order to foster adequate gender-related knowledge and skills for future doctors concerning the etiology, pathogenesis, clinical presentation, diagnosis, treatment, and research of diseases. A change agent was integrated directly into the curriculum development team to facilitate interactions with all key players of the curricular development process. The gender change agent established a supporting organizational framework of all stakeholders, and developed a 10-step approach including identification, selection, placing relevant sex and gender medicine-related issues in the curricular planning sessions, counseling of faculty members, and monitoring of the integration achieved. With this approach, quantitatively sex and gender medicine-related content was widely integrated throughout all teaching and learning formats and from early basic science to later clinical modules (94 lectures, 33 seminars, and 16 practical courses). Gender perspectives involve 5% of the learning objectives and represent an integral part of the assessment program. Qualitatively, the relevance of gender (sociocultural) differences was combined with sex (biological) differences in disease manifestation throughout the curriculum. The appointment of a change agent facilitates the development of systematic approaches that can be a key and serve as practice models to successfully integrate new overarching curricular perspectives and dimensions--in this case sex and gender medicine--into a new medical curriculum.

It is theorized that intranasal cavity volumes change throughout the aging process, possibly secondary to hormonal changes and atrophy of the sinonasal mucosa. Our objective is to compare intranasal volumes from different age groups to test the hypothesis that intranasal cavity volume increases with age. Case series. An analysis of computed tomography (CT) scans performed for reasons other than sinonasal complaints. Intranasal volumes of three groups (age 20-30 years, 40-50 years, and 70 years and above) were calculated using Vitrea software. The total intranasal volume was measured from the nasal vestibule anteriorly, the nasopharynx posteriorly, the olfactory cleft superiorly, and the nasal floor inferiorly. The total volume included the sum of the right and left sides. Sixty-two CT scans were analyzed. There was a progressive, relatively linear, increase in intranasal volume with increasing age: 20 to 30 years = 15.73 mL, 40 to 50 years = 17.30 mL, and 70 years and above = 18.38 mL. Mean intranasal volume for males was 19.07 mL, and for females was 15.23 mL. Analysis of variance demonstrated significant group differences in mean intranasal volume for age (P = .003) and gender (P < .001), with moderate-to-large effect size of 0.206 and 0.289 (partial η(2) ), respectively. Post hoc testing revealed a significant difference between the 20 to 30-year and >70-year age groups (P = .006). There was no significant difference in intranasal volume dependent upon body mass index. Intranasal volume increases with age and is larger in males. Specific etiologies responsible for increased intranasal cavity volume with age are actively being evaluated. 4 Laryngoscope, 126:2212-2215, 2016. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

Osteoarthritis (OA) is the most frequent and symptomatic health problem in the middle-aged and elderly population, with over one-half of all people over the age of 65 showing radiographic changes in painful knees. The aim of the present study was to perform an overview on the available animal models used in the research field on the OA. Discrepancies between the animal models and the human disease are present. As regards human 'idiopathic' OA, with late onset and slow progression, it is perhaps wise not to be overly enthusiastic about animal models that show severe chondrodysplasia and very early OA. Advantage by using genetically engineered mouse models, in comparison with other surgically induced models, is that molecular etiology is known. Find potential molecular markers for the onset of the disease and pay attention to the role of gender and environmental factors should be very helpful in the study of mice that acquire premature OA. Surgically induced destabilization of joint is the most widely used induction method. These models allow the temporal control of disease induction and follow predictable progression of the disease. In animals, ACL transection and meniscectomy show a speed of onset and severity of disease higher than in humans after same injury.

Rheumatoid arthritis is the most common systematic autoimmune disease and its etiology is believed to have both strong genetic and environmental components. We demonstrate the utility of including genetic and clinical phenotypes as covariates within a linkage analysis framework to search for rheumatoid arthritis susceptibility loci. The raw genotypes of 1302 affected relative pairs were combined from four large family-based samples (North American Rheumatoid Arthritis Consortium, United Kingdom, European Consortium on Rheumatoid Arthritis Families, and Canada). The familiality of the clinical phenotypes was assessed. The affected relative pairs were subjected to autosomal multipoint affected relative-pair linkage analysis. Covariates were included in the linkage analysis to take account of heterogeneity within the sample. Evidence of familiality was observed with age at onset (p << 0.001) and rheumatoid factor (RF) IgM (p << 0.001), but not definite erosions (p = 0.21). Genome-wide significant evidence for linkage was observed on chromosome 6. Genome-wide suggestive evidence for linkage was observed on chromosomes 13 and 20 when conditioning on age at onset, chromosome 15 conditional on gender, and chromosome 19 conditional on RF IgM after allowing for multiple testing of covariates.

Combat experience and problem drinking in veterans: Exploring the roles of PTSD, coping motives, and perceived stigma.

PubMed

Miller, Stephen M; Pedersen, Eric R; Marshall, Grant N

2017-03-01

The current investigation sought to illustrate the etiology of adverse alcohol consequences in young adult veterans using a path analytic framework. A total of 312 veterans aged 19-34 were enrolled in a larger intervention study on alcohol use. At baseline, participants completed measures of combat severity, PTSD symptom severity, and drinking motives to cope. At one month follow-up, participants completed measures of perceived stigma of behavioral health treatment seeking and past 30-day alcohol consequences. After entering the covariates of age, gender, race/ethnicity, and past year behavioral health treatment utilization, a path analytic model demonstrated a good fit to the data predicting alcohol consequences in this population. Further, a separate exploratory analysis confirmed that both drinking motives to cope and perceived stigma of behavioral health treatment seeking mediated the link between PTSD symptom severity and alcohol consequences. The current model expands upon prior research showing the relationship between combat severity and alcohol use behavior in young adult veterans. Results support the notion that veterans with PTSD symptoms may drink to cope and that perceived stigma surrounding help seeking may further contribute to alcohol related problems.

To test the null hypothesis that mouth-breathing (MB) children by distinct obstructive tissues present a similar cephalometric pattern. The sample included 226 prepubescent children (113 MB and 113 nasal breathing (NB) controls). An ENT clinical examination, including flexible nasal endoscopy, orthodontic clinical and cephalometric examinations, was performed on the MB population. MB children were grouped into three categories, according to the obstructive tissues: 1) adenoid group (AG), 2) tonsillar group (TG), and 3) adenotonsillar group (ATG). The NB controls were matched by gender, age, sagittal dental relationship and skeletal maturation status. Lateral cephalometric radiography provided the cephalometric pattern comparisons between the MB and NB groups. MB cephalometric measurements were significantly different from those of NB children, exception in the SNB° (P=0.056). All comparisons between the three groups of MB children with the NB children showed a significant difference. Finally, even among the three groups of MB children, a significant difference was observed in the measurements of the SNB° (P<0.036), NSGn° (P<0.028) and PFH/TAFH ratio (posterior facial height/total anterior facial height) (P<0.012). The cephalometric pattern of MB and NB children was not similar. Cephalometric measurements of the MB group differed according to the etiology of upper airway obstruction. Children with isolated hypertrophy of the palatine tonsils presented with a mandible that was positioned more forward and upward compared to children obstructed only by the enlarged adenoid.

2007-01-01

Kohlberg's (1966) hypothesis that the attainment of gender constancy motivates children to attend to gender norms was reevaluated by examining these links in relation to age. Ninety-four 3- to 7-year-old children were interviewed to assess whether and how constancy mediates age-related changes in gender-related beliefs. As expected, results indicated a general pattern of an increase in stereotype knowledge, the importance and positive evaluation of one's own gender category, and rigidity of beliefs between the ages of 3 and 5. Moreover, the stability phase, rather than full constancy, mediated some of these relations. After age 5, rigidity generally decreased with age, with relations primarily mediated by consistency.

Gender, aging, and the economics of "active aging": Setting a new research agenda.

PubMed

Paz, Amira; Doron, Israel; Tur-Sinai, Aviad

2018-01-01

The world is aging, and the percentages of older people are on a dramatic ascent. This dramatic demographic aging of human society is not gender neutral; it is mostly about older women. One of the key policy approaches to address the aging revolution is known as "active aging," crystalized by the WHO in 2002 by three pillars: participation, health, and security. The active aging policy has financial and economic aspects and affects both men and women. However, as argued in this article, a gender-based approach has not been adopted within the existing active aging framework. Therefore, a new gender-specific research agenda is needed, one that focuses on an interrelation between gender and different economic aspects of "active aging" from international, comparative, cultural, and longitudinal perspectives.

Searching for the Kinkeepers: Historian Gender, Age, and Type 2 Diabetes Family History.

2015-12-01

Kinkeepers facilitate family communication and may be key to family medical history collection and dissemination. Middle-aged women are frequently kinkeepers. Using type 2 diabetes (T2DM) as a model, we explored whether the predicted gender and age effects of kinkeeping can be extended to family medical historians. Through a U.S. telephone survey, nondiabetic Mexican Americans (n = 385), Blacks (n = 387), and Whites (n = 396) reported family histories of T2DM. Negative binomial regressions used age and gender to predict the number of affected relatives reported. Models were examined for the gender gap, parabolic age effect, and gender-by-age interaction predicted by kinkeeping. Results demonstrated support for gender and parabolic age effects but only among Whites. Kinkeeping may have application to the study of White family medical historians, but not Black or Mexican American historians, perhaps because of differences in family structure, salience of T2DM, and/or gender roles. © 2015 Society for Public Health Education.

The role of NT-proBNP in explaining the variance in anaerobic threshold and VE/VCO(2) slope.

2011-01-01

We investigated whether anaerobic threshold (AT) and ventilatory efficiency (minute ventilation/carbon dioxide production slope, VE/VCO2 slope), both significantly associated with mortality, can be predicted by questionnaire scores and/or other laboratory measurements. Anaerobic threshold and VE/VCO(2) slope, plasma N-terminal pro-brain natriuretic peptide (NT-proBNP), and the echocardiographic markers left ventricular ejection fraction (LVEF) and left atrial (LA) diameter were measured in 62 patients with heart failure (HF), who also completed the Minnesota Living with Heart Failure Questionnaire (MLHF), and the Specific Activity Questionnaire (SAQ). Linear regression models, adjusting for age and gender, were fitted. While the etiology of HF, SAQ score, MLHF score, LVEF, LA diameter, and logNT-proBNP were each significantly predictive of both AT and VE/VCO2 slope on stepwise multiple linear regression, only SAQ score (P < .001) and logNT-proBNP (P = .001) were significantly predictive of AT, explaining 56% of the variability (adjusted R(2) = 0.525), while logNT-proBNP (P < .001) and etiology of HF (P = .003) were significantly predictive of VE/VCO(2) slope, explaining 49% of the variability (adjusted R(2) = 0.45). The area under the ROC curve for NT-proBNP to identify patients with a VE/VCO(2) slope greater than 34 and AT less than 11 mL · kg(-1) · min(-1) was 0.797; P < .001 and 0.712; P = .044, respectively. A plasma concentration greater than 429.5 pg/mL (sensitivity: 78%; specificity: 70%) and greater than 674.5 pg/mL (sensitivity: 77.8%; specificity: 65%) identified a VE/VCO(2) slope greater than 34 and AT lower than 11 mL · kg(-1) · min(-1), respectively. NT-proBNP is independently related to both AT and VE/VCO(2) slope. Specific Activity Questionnaire score is independently related only to AT and the etiology of HF only to VE/VCO(2) slope.

This study examined factors that predicted children's gender intergroup attitudes at age 5 and the implications of these attitudes for intergroup behavior. Ethnically diverse children from low-income backgrounds (N = 246; Mexican-, Chinese-, Dominican-, and African American) were assessed at ages 4 and 5. On average, children reported positive same-gender and negative other-gender attitudes. Positive same-gender attitudes were associated with knowledge of gender stereotypes. In contrast, positive other-gender attitudes were associated with flexibility in gender cognitions (stereotype flexibility, gender consistency). Other-gender attitudes predicted gender-biased behavior. These patterns were observed in all ethnic groups. These findings suggest that early learning about gender categories shape young children's gender attitudes and that these gender attitudes already have consequences for children's intergroup behavior at age 5. © 2016 The Authors.

2010-01-01

Functional somatic symptoms (FSS) are symptoms not explained by underlying organic pathology. It has frequently been suggested that dysfunction of the autonomic nervous system (ANS) contributes to the development of FSS. We hypothesized that decreased cardiac vagal activity is cross-sectionally and prospectively associated with the number of FSS in the general population. This study was performed in a population-based cohort of 774 adults (45.1% male, mean age +/- SD 53.5 +/- 10.7 years). Participants completed the somatization section of the Composite International Diagnostic Interview surveying the presence of 43 FSS. ANS function was assessed by spectral analysis of heart rate variability in the high-frequency band (HRV-HF), reflecting cardiac vagal activity. Follow-up measurements of HRV-HF and FSS were performed approximately 2 years later. Linear regression analyses, with adjustments for gender, age, body mass index, anxiety, depression, smoking, alcohol use, and frequency of exercise, revealed an interaction of cardiac vagal activity with age: HRV-HF was negatively associated with FSS in adults 52 years (beta = 0.13, t = 2.51, p = 0.012). Longitudinal analysis demonstrated a similar pattern. Decreased cardiac vagal activity is associated with a higher number of FSS in adults aged 52 years needs further exploration. The role of age should be acknowledged in future studies on ANS function in the etiology of FSS. (c) 2010 S. Karger AG, Basel.

Diagnosis of secondary hypertension: an age-based approach.

PubMed

Viera, Anthony J; Neutze, Dana M

2010-12-15

Secondary hypertension is a type of hypertension with an underlying, potentially correctable cause. A secondary etiology may be suggested by symptoms (e.g., flushing and sweating suggestive of pheochromocytoma), examina- tion findings (e.g., a renal bruit suggestive of renal artery stenosis), or laboratory abnormalities (e.g., hypokalemia suggestive of aldosteronism). Secondary hypertension also should be considered in patients with resistant hyper- tension, and early or late onset of hypertension. The prevalence of secondary hypertension and the most common etiologies vary by age group. Approximately 5 to 10 percent of adults with hypertension have a secondary cause. In young adults, particu- larly women, renal artery stenosis caused by fibromuscular dyspla- sia is one of the most common secondary etiologies. Fibromuscular dysplasia can be detected by abdominal magnetic resonance imag- ing or computed tomography. These same imaging modalities can be used to detect atherosclerotic renal artery stenosis, a major cause of secondary hypertension in older adults. In middle-aged adults, aldosteronism is the most common secondary cause of hyperten- sion, and the recommended initial diagnostic test is an aldosterone/ renin ratio. Up to 85 percent of children with hypertension have an identifiable cause, most often renal parenchymal disease. Therefore, all children with confirmed hypertension should have an evaluation for an underlying etiology that includes renal ultrasonography.

The etiology of anomalous sexual preferences in men.

PubMed

Quinsey, Vermon L

2003-06-01

People discover rather than choose their sexual interests. The process of discovery typically begins before the onset of puberty and is associated with an increase in the secretion of sex hormones from the adrenal glands. However, the determinants of the direction of sexual interest, in the sense of preferences for the same or opposite sex, are earlier. These preferences, although not manifest until much later in development, appear to be caused by the neural organizational effects of intrauterine hormonal events. Variations in these hormonal events likely have several causes and two of these appear to have been identified for males. One cause is genetic and the other involves the sensitization of the maternal immune system to some aspect of the male fetus. It is presently unclear how these two causes relate to each other. The most important question for future research is whether preferences for particular-aged partners and parts of the male courtship sequence share causes similar to those of erotic gender orientation.

This study examines the contribution of the lexical/verbal channel to emotional processing in 16 right brain-damaged (RBD), 16 left brain-damaged (LBD) and 16 normal control (NC) right-handed adults. Emotional lexical perception tasks were developed; analogous nonemotional tasks were created to control for cognitive and linguistic factors. The three subject groups were matched for gender, age and education. The brain-damaged groups were similar with respect to cerebrovascular etiology, months post-onset, sensory-motor status and lesion location. Parallel emotional and nonemotional tasks included word identification, sentence identification and word discrimination. For both word tasks, RBDs were significantly more impaired than LBDs and NCs in the emotional condition. For all three tasks, RBDs showed a significantly greater performance discrepancy between emotional and nonemotional conditions than did LBDs or NCs. Results were not affected by the valence (i.e. positive/negative) of the stimuli. These findings suggest a dominant role for the right hemisphere in the perception of lexically-based emotional stimuli.

Parental Invalidation and the Development of Narcissism.

Huxley, Elizabeth; Bizumic, Boris

Parenting behaviors and childhood experiences have played a central role in theoretical approaches to the etiology of narcissism. Research has suggested an association between parenting and narcissism; however, it has been limited in its examination of different narcissism subtypes and individual differences in parenting behaviors. This study investigates the influence of perceptions of parental invalidation, an important aspect of parenting behavior theoretically associated with narcissism. Correlational and hierarchical regression analyses were conducted using a sample of 442 Australian participants to examine the relationship between invalidating behavior from mothers and fathers, and grandiose and vulnerable narcissism. Results indicate that stronger recollections of invalidating behavior from either mothers or fathers are associated with higher levels of grandiose and vulnerable narcissism when controlling for age, gender, and the related parenting behaviors of rejection, coldness, and overprotection. The lowest levels of narcissism were found in individuals who reported low levels of invalidation in both parents. These findings support the idea that parental invalidation is associated with narcissism.

The etiology of Parkinson's disease (PD) is not well established. Genetic variation in fibroblast growth factor 20 (FGF20) might influence the risk of PD occurrence and development. In this study, Two DNA polymorphisms at genetic variation in FGF20, rs2720208 (C/T) and rs1721100 (C/G), were genotyped by direct sequencing in Han Chinese population, including 394 PD patients and 383 healthy controls. Statistical analyses revealed that for rs1721100 (C/G) polymorphism, there were significant differences in genotype distribution between PD and healthy-matched controls. For rs12720208 (C/T) polymorphism, there was no significant difference in genotype distribution and gender and age-related differences between PD and control group. Results in this study revealed that the rs1721100(C/G) polymorphism is a risk factor for PD in Han Chinese population, while rs12720208(C/T) polymorphism is not significantly associated with PD.

The prevalence of hyperthyroidism in women is between 0.5-2% and it is 10 times less common in men. The most common causes are Graves' disease, toxic multinodular goiter, and autonomously functioning thyroid adenoma. Rare causes of hyperthyroidisms are as follow: pituitary adenoma, autoimmune thyroiditis (Hashitoxicosis), levothyroxine overdose, inadequate iodine supplementation (including amiodaron induced hyperthyroidism, iodine-based contrast media), hCG excess (pregnancy, gestational trophoblastic disease, germ-cell tumors), drug induced hyperthyroidism, differentiated thyroid carcinomas and/or their metastases, struma ovarii, and familial nonautoimmune hyperthyroidism. This article focuses on the current data of etiopathogenesis of hyperthyroidisms. Genetic factors (like HLA-DR3,CD40, CTLA-4, PTPN22, FOXP3 CD25) and thyroid specific genes (thyroglobulin, TSHR, G(s)alpha) and environmental and endogenous factors (such as age, iodine, selenium, emotional stress, smoking, gender, pregnancy, sex hormones, fetal microchimerism, fetal growth, bacterial infections, viral infections, allergies, drugs (alemtuzumab, interferon alpha, iplimumab/tremelimumab, tyrosine kinase inhibitors, denileukindiftitox, thalidomide/lenalidomide, exposition to fallout and radiotherapy) have been described.

Kawasaki disease (KD) in an acute vasculitis of unknown etiology. The epidemiological data available for Algerian patients remains insufficient. To describe the demographic, clinical features of children with KD and to identify the risk factors for developing coronary artery lesions (CAL). This retrospective study included children admitted with KD at the pediatric hospital in Algiers from January 2005 to December 2014. One hundred thirty-three patients (82 boys and 51 girls) with a mean age of 31 months were identified. The most common sign was fever, rash, oral changes and conjunctivitis. The cardiac complications were CAL (22.5%), pericarditis (2%) and myocarditis (1.5%). The independent variable for prediction of CAL was duration of fever >10 days, male gender and platelet count >450,000/mm3 CONCLUSION: The incidence of cardiovascular complications is high. Knowledge of KD among Algerian pediatricians should be enhanced to guarantee appropriate treatment of this disease. © The Author 2015. Published by Oxford University Press. All rights reserved.

Age and gender are two important physiological variables which might influence the personality of an individual. The influence of age and gender on big five personality domains in Indian population was assessed in this cross-sectional study that included 155 subjects (female = 76, male = 79) aged from 16-75 years. Big five personality factors were evaluated using 60-item NEO-Five Factor Inventory (NEO-FFI) at a single point in time. Among the big five factors of personality, Conscientiousness was positively correlated (r = 0.195; P < 0.05) with age in total study population, and retained the significance (P < 0.05) in men only when analyzed by gender subgroups. Further, age and gender sub-group analysis also showed that Neuroticism was inversely correlated with age in women aged 26-35 years (P < 0.05). Neuroticism and Extraversion showed a positive correlation with age in men aged 36-45 years (P < 0.001 and P < 0.05, respectively). Neuroticism was inversely correlated with age in men aged 46-55 years (P < 0.05). This preliminary report suggested that personality traits might change with age, and is gender-dependent.

Older paternal age has previously been documented as a factor in sporadic fresh mutational cases of several autosomal dominant disorders. In this collaborative study, an older mean paternal age has been documented in sporadic cases of at least five additional dominantly inheritable disorders; the basal cell nevus syndrome, the Waardenburg syndrome, the Crouzon syndrome, the oculo-dental-digital sysdrome, and the Treacher-Collins syndrome. It was also found to be a factor in acrodysostosis and progeria, suggesting a fresh mutant gene etiology for these two conditions in which virtually all cases have been sporadic and the mode of genetic etiology has been unknown.

Despite a range of research on gender identity disorder (GID), at present there is no scientific consensus on whether the etiology of GID is mental or physical. In particular recent advances in the technology of neuroimaging research have led to an increased understanding of the biological basis of various mental disorders. GID also should be evaluated from this perspective. The aim of the present study was therefore to do the first trial to examine the regional cerebral blood flow (rCBF) in GID. Persons considered biologically male fulfilling the GID criteria are termed male to female (MTF) and, conversely, persons considered biological female are termed female to male (FTM). We compared 11 FTM subjects and nine age- and handedness-matched female control subjects. None of the subjects was regularly taking medication and none had any kind of physical or psychiatric comorbidity. To evaluate rCBF in GID subjects and control subjects, statistical parametric mapping analysis of (99m)Tc-ethyl-cysteinate dimer single-photon emission computed tomography was used. GID subjects had a significant decrease in rCBF in the left anterior cingulate cortex (ACC) and a significant increase in the right insula compared to control subjects. The ACC and insula are regions that have been noted as being related to human sexual behavior and consciousness. From these findings, useful insights into the biological basis of GID were suggested.

To assess whether vardenafil would improve erectile function irrespective of etiology, baseline severity, or patient age. The consistency of the response over time was also evaluated. A multicenter, randomized, double-blind, placebo-controlled at-home study of vardenafil treatment (5, 10, and 20 mg) was performed. This secondary analysis compared the mean International Index of Erectile Function (IIEF) erectile function domain scores of various subgroups at 12 weeks of treatment. These populations included organic, psychogenic, or mixed etiologies; mild, moderate, or severe baseline severity; and four age groups (younger than 45, 45 to 55, 56 to 65, and older than 65 years). In addition, all IIEF domains were compared at sequential 4-week periods, before and during treatment. In the 580 men of the intent-to-treat population, the mean erectile function domain scores were statistically greater than placebo, irrespective of etiology, baseline severity, or age. This was seen at all dosages. Compared with placebo, vardenafil statistically improved the IIEF domain scores of erectile function, orgasmic function, intercourse satisfaction, and overall satisfaction after 4 weeks of treatment, and these improvements were maintained for 12 weeks. The rates of the most common adverse events (headache, flushing, and dyspepsia) were either constant or declined over time; they were generally mild to moderate and transient in nature. Vardenafil improved erectile function regardless of the general etiology, baseline severity of erectile dysfunction, or patient age. Improvements in erectile function and other key IIEF domains were consistently seen throughout the study.

Polypoidal choroidal vasculopathy (PCV) and neovascular age-related macular degeneration (AMD) are prevalent age-related diseases characterized by exudative changes in the macula. Although they share anatomical and clinical similarities, they are also distinctly characterized by their own features, e.g. vascular abnormalities in PCV and drusen-mediated progression in neovascular AMD. PCV remains etiologically uncharacterized, and ongoing discussion is whether PCV and neovascular AMD share the same etiology or constitute two substantially different diseases. In this study, we investigated T-cell differentiation and aging profile in human patients with PCV, patients with neovascular AMD, and age-matched healthy control individuals. Fresh venous blood was prepared for flow cytometry to investigate CD4 + and CD8 + T-cell differentiation (naïve, central memory, effector memory, effector memory CD45ra + ), loss of differentiation markers CD27 and CD28, and expression of aging marker CD56. Patients with PCV were similar to the healthy controls in all aspects. In patients with neovascular AMD we found significantly accelerated T-cell differentiation (more CD28 - CD27 - cells) and aging (more CD56 + cells) in the CD8 + T-cell compartment. These findings suggest that PCV and neovascular AMD are etiologically different in terms of T cell immunity, and that neovascular AMD is associated with T-cell immunosenescence.

Etiologic profile of spastic quadriplegia in children.

Venkateswaran, Sunita; Shevell, Michael I

2007-09-01

The etiologic profile and possible predictors of etiology in children with spastic quadriplegia were assessed in a consecutive cohort of children with this motor impairment. Medical records from a single pediatric neurology practice over a 14-year interval were retrospectively and systematically reviewed. Variables comprised possible demographic, prenatal, perinatal, and postnatal risk factors. Of the 99 patients included in the study, 39 were premature (<37 weeks gestation). The overall etiologic yield was 83%. The top three diagnoses were hypoxic-ischemic perinatal asphyxia (33%), periventricular leukomalacia (15%), and central nervous system infections (11%). In premature children, the most common diagnoses were periventricular leukomalacia (33%), perinatal asphyxia (26%), and central nervous system infections (15%). In term-born children, the most frequent diagnoses were perinatal asphyxia (37%), metabolic disease (12%), and structural malformation or infection (9% each). Factors predicting the identification of an etiology included male sex (P = 0.05), low birth weight (P = 0.003), prematurity (P = 0.01), perinatal complications (P = 0.002), and neonatal encephalopathy (P = 0.006). The etiologic yield in patients with spastic quadriplegia was 83%, with differing underlying etiologies depending on gestational age. These results should help guide physicians in investigating possible underlying etiologies in patients with spastic quadriplegia.

Data showing a remarkable gender difference in life expectancy and mortality, including survival to extreme age, are reviewed starting from clinical and demographic data and stressing the importance of a comprehensive historical perspective and a gene–environment/lifestyle interaction. Gender difference regarding prevalence and incidence of the most important age-related diseases, such as cardiovascular and neurodegenerative diseases, cancer, Type 2 diabetes, disability, autoimmunity and infections, are reviewed and updated with particular attention to the role of the immune system and immunosenescence. On the whole, gender differences appear to be pervasive and still poorly considered and investigated despite their biomedical relevance. The basic biological mechanisms responsible for gender differences in aging and longevity are quite complex and still poorly understood. The present review focuses on centenarians and their offspring as a model of healthy aging and summarizes available knowledge on three basic biological phenomena, i.e. age-related X chromosome inactivation skewing, gut microbiome changes and maternally inherited mitochondrial DNA genetic variants. In conclusion, an appropriate gender-specific medicine approach is urgently needed and should be systematically pursued in studies on healthy aging, longevity and age-related diseases, in a globalized world characterized by great gender differences which have a high impact on health and diseases.

Atypical respiratory sinus arrhythmia (RSA), a biomarker of emotion dysregulation, is associated with both externalizing and internalizing behaviors. In addition, social adversity and gender may moderate this association. In this study, we investigated if RSA (both resting RSA and RSA reactivity in an emotion regulation task) predicts externalizing and/or internalizing behaviors and the extent to which social adversity moderates this relationship. Two hundred and fifty-three children (at Time 1, mean age = 9.05, SD = 0.60, 48% boys) and their caregivers from the community participated in this study. Resting RSA and RSA reactivity were assessed, and caregivers reported children’s externalizing and internalizing behaviors at both Time 1 and Time 2 (1 year later). We found that lower resting RSA (but not RSA reactivity) at Time 1 was associated with increased externalizing and internalizing behaviors at Time 2 in boys, even after controlling for the effects of Time 1 behavioral problems and Time 2 age. Moreover, there was a significant interaction effect between Time 1 resting RSA and social adversity such that lower resting RSA predicted higher externalizing and internalizing behaviors in boys only under conditions of high social adversity. Follow-up analyses revealed that these predictive effects were stronger for externalizing behavior than for internalizing behavior. No significant effects were found for girls. Our findings provide further evidence that low resting RSA may be a transdiagnostic biomarker of emotion dysregulation and a predisposing risk factor for both types of behavior problems, in particular for boys who grow up in adverse environments. We conclude that biosocial interaction effects and gender differences should be considered when examining the etiological mechanisms of child psychopathology. PMID:28955262

The elevated risk for incident head and neck cancer among human papillomavirus (HPV)-16-seropositive individuals has substantiated a role for HPV in the etiology of head and neck cancers. The relationship between HPV seroreactivity and prevalent oral HPV infection in men and women without cancer has yet to be investigated. The goal of this study was to evaluate a possible association between oral HPV infection and HPV seroreactivity after adjustment for gender, sexual behaviors, and sexually transmitted disease. A cross-sectional study of factors associated with HPV-16, -18, and -33 seroreactivity was performed in a population of 586 men and women with and without HIV infection. Antibodies in sera were measured by use of a virus-like protein (VLP)-based enzyme-linked immunosorbent assay. Exfoliated cells from the tonsillar and oral mucosa were analyzed for the presence of 38 mucosal HPV types by polymerase chain reaction. Women had significantly greater seroreactivity for all HPV types investigated when compared with men (odds ratio, 4.3; 95% confidence interval, 3.0-6.0). Seroprevalence was greatest in men and women aged 35 to 45 years. Tonsillar HPV infection, oral sex with men, and HIV infection were independently associated with HPV seroreactivity in men after adjustment for age and number of sexual partners. In women, HSV-2 seropositivity and a history of sexually transmitted diseases were similarly important. Oral and tonsillar HPV infection were not associated with HPV seroreactivity in women. HPV seropositivity is associated with sexually transmitted diseases among women and possibly mucosal HPV exposures in men. Tonsillar HPV infection could impact seroprevalence, particularly in men.

Neuropathic pain affects various dimensions of patient health including physical, psychological, and socioeconomic. The spectrum of psychological dysfunction that accompanies this pain phenotype is unknown, as well as differences based on the etiology of the pain among patients referred for spinal cord stimulation (SCS). We prospectively assessed SCS referral patients with neuropathic pain for features of psychological distress, either mood or anxiety. Demographic data included age, gender, diagnosis, marital status, and educational level. Screening tools were applied for neuropathic pain (Douleur Neuropathic Quatre and Leeds Assessment of Neuropathic Symptoms and Signs) and psychological distress (Beck Depression Inventory [BDI] and Beck Anxiety Inventory [BAI]). Descriptive statistics defined disease prevalence, compared by gender and diagnosis. Logistic regression correlated pain intensity with severity of psychopathology. Among 150 patients with suitable neuropathic pain diagnoses and no treatable structural pathology, 57% were women, median age was 54 years, and 35% and 42% admitted to routine smoking and alcohol use, respectively. The most common diagnoses were complex regional pain syndrome (46%) and failed back surgery syndrome (38%). Depression symptoms were screened positive by BDI in 63% of patients, and anxiety symptoms were screened positive by BAI in 23% of patients. Pain intensity correlated with BDI scores (p < 0.02) but not BAI scores (p = 0.43). The high frequency of depressive and anxiety symptoms screened by the Beck scores in this cohort is an order of magnitude higher than seen in the general population. That many of these cases are undiagnosed should motivate clinicians from primary care providers, comprehensive pain specialists, and surgeons to screen SCS patients for such psychopathology. This represents an opportunity to enhance overall pain management as well as success with invasive neuromodulation strategies. © 2015 International Neuromodulation Society.

Inadequate physical activity and obesity during adolescence are areas of public health concern. Questions exist about the role of neighborhoods in the etiology of these problems. This research addressed the relationships of perceived and objective reports of neighborhood crime to adolescent physical activity, screen media use, and body mass index (BMI). Socioeconomically and racially/ethnically diverse adolescents (N = 2,455, 53.4% female) from 20 urban, public middle and high schools in Minneapolis/St. Paul, Minnesota responded to a classroom survey in the Eating and Activity in Teens 2010 study. BMI was measured by research staff. Participants' mean age was 14.6 (standard deviation = 2.0); 82.7% represented racial/ethnic groups other than non-Hispanic white. Linear regressions examined associations between crime perceived by adolescents and crime reported to police and the outcomes of interest (BMI z-scores, physical activity, and screen time). Models were stratified by gender and adjusted for age, race/ethnicity, socioeconomic status, and school. BMI was positively associated with perceived crime among girls and boys and with reported crime in girls. For girls, there was an association between higher perceived crime and increased screen time; for boys, between higher reported property crime and reduced physical activity. Perceived crime was associated with reported crime, both property and personal, in both genders. Few prior studies of adolescents have studied the association between both perceived and reported crime and BMI. Community-based programs for youth should consider addressing adolescents' safety concerns along with other perceived barriers to physical activity. Interventions targeting actual crime rates are also important. Copyright © 2015 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

Numerous studies have reported an association between stressing work conditions and cardiovascular disease. However, more evidence is needed, and the etiological mechanisms are unknown. Elevated resting heart rate has emerged as a possible risk factor for cardiovascular disease, but little is known about the relation to work-related stress. This study therefore investigated the association between job strain, job control, and job demands and resting heart rate. We conducted a cross-sectional survey of randomly selected men and women in Västra Götalandsregionen, Sweden (West county of Sweden) (n = 1552). Information about job strain, job demands, job control, heart rate and covariates was collected during the period 2001-2004 as part of the INTERGENE/ADONIX research project. Six different linear regression models were used with adjustments for gender, age, BMI, smoking, education, and physical activity in the fully adjusted model. Job strain was operationalized as the log-transformed ratio of job demands over job control in the statistical analyses. No associations were seen between resting heart rate and job demands. Job strain was associated with elevated resting heart rate in the unadjusted model (linear regression coefficient 1.26, 95 % CI 0.14 to 2.38), but not in any of the extended models. Low job control was associated with elevated resting heart rate after adjustments for gender, age, BMI, and smoking (linear regression coefficient -0.18, 95 % CI -0.30 to -0.02). However, there were no significant associations in the fully adjusted model. Low job control and job strain, but not job demands, were associated with elevated resting heart rate. However, the observed associations were modest and may be explained by confounding effects.

The influence of child gender role and maternal feedback to child stress on the emergence of the gender difference in depressive rumination in adolescence.

Extensive research has linked a greater female tendency to ruminate about depressed feelings or mood to the gender difference in depression. However, the developmental origins of the gender difference in depressive rumination are not well understood. We hypothesized that girls and women may be more likely to ruminate because rumination represents a gender-stereotyped coping style that is associated with a more feminine gender role identity, maternal encouragement of emotion expression, and passive coping responses to stress. This study examined whether child self-reported gender role identity and observed maternal responses to child stress mediated the emergent gender difference in depressive rumination in adolescence. Maternal gender role attitudes were further hypothesized to moderate the relationship between child sex and mediating variables. Rumination and gender role identity were assessed in 316 youths and their mothers in a longitudinal study from age 11 to age 15; in addition, 153 mother-child dyads participated in an observational task at age 11 from which maternal responses to a child stressor were coded. Results indicated that greater feminine gender role identity among children and encouragement of emotion expression by mothers at age 11 significantly mediated the association between child sex and the development of depressive rumination at age 15, even after controlling for rumination at age 11. Maternal gender role attitudes significantly moderated the relationship between child sex and maternal encouragement of emotion expression, such that mothers who endorsed more traditional gender role attitudes themselves were particularly likely to encourage emotion expression in their daughters.

Identifying risk factors for depression is important for understanding etiological mechanisms and targeting preventive efforts. No prior studies have compared risk factors of dysthymia and major depressive disorder (MDD) in a longitudinal setting. Predictors of new-onset MDD and dysthymia were examined in a longitudinal general population study (Health 2000 and 2011 Surveys, BRIF8901). 4057 persons free of depressive disorders at baseline were followed up for 11 years. DSM-IV MDD and dysthymia were diagnosed with the Composite International Diagnostic Interview. 126 persons (4.4%, 95%CI 3.6-5.2) were diagnosed with MDD or dysthymia at follow-up. Predictors of new-onset depressive disorders were younger age (adjusted OR 0.97, 95%CI 0.95-0.99 per year), female gender (aOR 1.46, 95%CI 1.01-2.12), multiple childhood adversities (aOR 1.76, 95%CI 1.10-2.83), low trust dimension of social capital (aOR 0.58, 95%CI 0.36-0.96 for high trust), baseline anxiety disorder (aOR 2.75, 95%CI 1.36-5.56), and baseline depressive symptoms (aOR 1.65, 95%CI 1.04-2.61 for moderate and aOR 2.49, 95%CI 1.20-5.17 for severe symptoms). Risk factors for MDD were younger age, female gender, anxiety disorder and depressive symptoms, whereas younger age, multiple childhood adversities, low trust, and having 1-2 somatic diseases predicted dysthymia. We only had one follow-up point at eleven years, and did not collect information on the subjects' health during the follow-up period. Persons with subclinical depressive symptoms, anxiety disorders, low trust, and multiple childhood adversities have a higher risk of depressive disorders. Predictors of MDD and dysthymia appear to differ. This information can be used to target preventive efforts and guide social policies. Copyright © 2016 Elsevier B.V. All rights reserved.

Sex and gender differences in the causes of dementia: a narrative review.

2014-10-01

This is a narrative review of new ideas and concepts related to differences between men and women in their risk of developing dementia or Alzheimer's disease (AD). We introduce the concept of dimorphic neurology and the distinction between sex and gender. We then provide three examples of risk factors related to sex and gender from the literature. Apolipoprotein E genotype is equally common in men and women but has a stronger effect in women. Apolipoprotein E genotype is a biological factor that cannot be modified but interacts with sex or gender related factors that can be modified. Low education has a similar harmful effect in men and women but has been historically more common in women. Education is a social factor related to gender that can be modified. Finally, bilateral oophorectomy is a factor restricted to women. Bilateral oophorectomy is a surgical practice related to sex that can be modified. Consideration of risk and protective factors in men and women separately may accelerate etiologic research for neurological diseases in general, and for dementia and AD in particular. Similarly, future preventive interventions for dementia should be tailored to men and women separately. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Biological origins of sexual orientation and gender identity: Impact on health.

PubMed

O'Hanlan, Katherine A; Gordon, Jennifer C; Sullivan, Mackenzie W

2018-04-01

Gynecologic Oncologists are sometimes consulted to care for patients who present with diverse gender identities or sexual orientations. Clinicians can create more helpful relationships with their patients if they understand the etiologies of these diverse expressions of sexual humanity. Multidisciplinary evidence reveals that a sexually dimorphic spectrum of somatic and neurologic anatomy, traits and abilities, including sexual orientation and gender identity, are conferred together during the first half of pregnancy due to genetics, epigenetics and the diversity of timing and function of sex chromosomes, sex-determining protein secretion, gonadal hormone secretion, receptor levels, adrenal function, maternally ingested dietary hormones, fetal health, and many other factors. Multiple layers of evidence confirm that sexual orientation and gender identity are as biological, innate and immutable as the other traits conferred during that critical time in gestation. Negative social responses to diverse orientations or gender identities have caused marginalization of these individuals with resultant alienation from medical care, reduced self-care and reduced access to medical care. The increased risks for many diseases, including gynecologic cancers are reviewed. Gynecologic Oncologists can potentially create more effective healthcare relationships with their patients if they have this information. Copyright © 2017 Elsevier Inc. All rights reserved.

Does Gender Matter? an Exploratory Study of Perspectives Across Genders, Age and Education

Carinci, Sherrie; Wong, Pia Lindquist

2009-11-01

Using a convenience sample and survey research methods, the authors seek to better understand how perspectives on gender are shaped by individuals' age, level of education and gender. Study participants responded in writing to scenarios and survey questions, revealing their personal views on gender as an identity category and as a marker in the social hierarchy. Analysis indicated that there were differences between male and female views on these dimensions of gender, and that age and educational levels were also influential. While younger respondents from both genders demonstrated flexibility in their definitions of gender and expressed strong support for gender equality, they were noticeably lacking in their knowledge of the historical context of gender relations and did not show the skills required to realise their ideals of gender equality, especially when compared to older respondents of both genders with higher levels of educational attainment.

Genetic and Environmental Influences on Achievement Outcomes Based on Family History of Learning Disabilities Status.

2018-05-01

A risk to develop a learning disability has been shown to run in families. Having a positive family history of learning disability seems to account for mean differences in achievement outcomes (reading, math) in that children with a positive family history score significantly lower compared to their peers with no such family history. However, the role of family history status in explaining etiological (genetic and environmental) differences among these subgroups of children has yet to be established. The present study of 872 twins ( M age = 13.30, SD age = 1.40) from the Florida Twin Project on Reading, Behavior, and Environment utilized a multigroup approach to examine etiological differences on reading, spelling, and math among two subgroups defined by family history status. Results showed significant mean differences on all achievement outcomes, aside from math; however, no significant etiological differences on any achievement outcome were found among the two subgroups. Results support previous literature that the risk for developing a learning disability is transmitted through a family, but this is seemingly not manifested by differential etiology.

Seventy five medico-surgical cases (52 men, with a mean age at surgery of 59, and 23 women, with a mean age at surgery of 59) collected between 1983 and 1989, in an ethnically homogeneous and geographically stable population (West Brittany) confirmed that the current anatomical and etiological aspects of chronic (or subacute) pure mitral incompetence (MI) have changed radically. While rates for bacterial and ischemic etiologies remain stable, the share of rheumatic MI (14 cases) has fallen considerably, to the advantage of degenerative MI (51 cases) with a heavy male predominance (39 men) with in 33 cases rupture of the main chordae, and tending to affect the lesser mitral cusp more often. A precise diagnosis in terms of lesions and etiology is possible in almost all cases on the basis of clinical history and echocardiographic findings. In a perfectly homogeneous population, chronic surgical pure MI is currently essentially a male disease, of dystrophic origin, in patients in the 6th and 7th decades of life.

The scope of this study was to construct an indicator of active aging and assess its association with quality of life and possible determinants according to gender. The AGEQOL (Aging, Gender and Quality of Life) study was used to interview 2052 individuals aged 60 years and older residing in Sete Lagoas in the State of Minas Gerais. The association between active aging, quality of life and possible determinants was performed by multiple logistic regression with a 5% level of statistical significance separately for each gender. Most men were in the active aging group (58%), and 51.8% of women were in the normal aging group (p < 0.001). The quality of life in the Physical, Psychological, and total Score domains remained associated with the outcome in the final model for both genders. Among the men, the behavioral and community participation factors were positive predictors of active aging. Women with higher incomes, who did not suffer falls and engaged in community participation, had a better chance of belonging to the active aging group. The conclusion drawn is that quality of life and participation in groups are the main determinants of active aging, and the other factors associated with active aging are different for each gender.

To determine the relationship between age and gray matter structure and how interactions between gender and hemisphere impact this relationship, we examined correlations between global or regional gray matter volume and age, including interactions of gender and hemisphere, using a general linear model with voxel-based and region-of-interest analyses. Brain magnetic resonance images were collected from 1460 healthy individuals aged 20–69 years; the images were linearly normalized and segmented and restored to native space for analysis of global gray matter volume. Linearly normalized images were then non-linearly normalized and smoothed for analysis of regional gray matter volume. Analysis of global gray matter volume revealed a significant negative correlation between gray matter ratio (gray matter volume divided by intracranial volume) and age in both genders, and a significant interaction effect of age × gender on the gray matter ratio. In analyzing regional gray matter volume, the gray matter volume of all regions showed significant main effects of age, and most regions, with the exception of several including the inferior parietal lobule, showed a significant age × gender interaction. Additionally, the inferior temporal gyrus showed a significant age × gender × hemisphere interaction. No regional volumes showed significant age × hemisphere interactions. Our study may contribute to clarifying the mechanism(s) of normal brain aging in each brain region. PMID:21818377

Toward a gender politics of aging.

2018-01-01

The article proposes a Gender Politics of Aging approach to the study of aging societies. The approach recognizes the feminization of old age, ageism's roots in sexist discourse, and the need to recognize the role of politics in driving demographic debates. Drawing together arguments from feminist gerontology and political demography, the article argues that the intersection of politics and gender must be considered if appropriate responses to an older, feminized demography are to be produced. I conclude that the work of aging feminists provides a rich vein of research and praxis from which a gender politics of aging approach can draw.

Intelligent digital signage systems transmit customized advertising and information by analyzing users and customers, unlike existing system that presented advertising in the form of broadcast without regard to type of customers. Currently, development of intelligent digital signage system has been pushed forward vigorously. In this study, we designed a system capable of analyzing gender and age of customers based on image obtained from camera, although there are many different methods for analyzing customers. We conducted age and gender recognition experiments using public database. The age/gender recognition experiments were performed through histogram matching method by extracting Local binary patterns (LBP) features after facial area on input image was normalized. The results of experiment showed that gender recognition rate was as high as approximately 97% on average. Age recognition was conducted based on categorization into 5 age classes. Age recognition rates for women and men were about 67% and 68%, respectively when that conducted separately for different gender.

To share our experience regarding the laparoscopic Frey procedure for chronic pancreatitis (CP) and patient selection. All consecutive patients undergoing duodenum-preserving pancreatic head resection from July 2013 to July 2014 were reviewed and those undergoing the Frey procedure for CP were included in this study. Data on age, gender, body mass index (BMI), American Society of Anesthesiologists score, imaging findings, inflammatory index (white blood cells, interleukin (IL)-6, and C-reaction protein), visual analogue score score during hospitalization and outpatient visit, history of CP, operative time, estimated blood loss, and postoperative data (postoperative mortality and morbidity, postoperative length of hospital stay) were obtained for patients undergoing laparoscopic surgery. The open surgery cases in this study were analyzed for risk factors related to extensive bleeding, which was the major reason for conversion during the laparoscopic procedure. Age, gender, etiology, imaging findings, amylase level, complications due to pancreatitis, functional insufficiency, and history of CP were assessed in these patients. Nine laparoscopic and 37 open Frey procedures were analyzed. Of the 46 patients, 39 were male (85%) and seven were female (16%). The etiology of CP was alcohol in 32 patients (70%) and idiopathic in 14 patients (30%). Stones were found in 38 patients (83%). An inflammatory mass was found in five patients (11%). The time from diagnosis of CP to the Frey procedure was 39 ± 19 (9-85) mo. The BMI of patients in the laparoscopic group was 20.4 ± 1.7 (17.8-22.4) kg/m(2) and was 20.6 ± 2.9 (15.4-27.7) kg/m(2) in the open group. All patients required analgesic medication for abdominal pain. Frequent acute pancreatitis or severe abdominal pain due to acute exacerbation occurred in 20 patients (43%). Pre-operative complications due to pancreatitis were observed in 18 patients (39%). Pancreatic functional insufficiency was observed in 14 patients (30%). Two laparoscopic patients (2/9) were converted. In seven successful laparoscopic cases, the mean operative time was 323 ± 29 (290-370) min. Estimated intra-operative blood loss was 57 ± 14 (40-80) mL. One patient had a postoperative complication, and no mortality was observed. Postoperative hospital stay was 7 ± 2 (5-11) d. Multiple linear regression analysis of 37 open Frey procedures showed that an inflammatory mass (P < 0.001) and acute exacerbation (P < 0.001) were risk factors for intra-operative blood loss. The laparoscopic Frey procedure for CP is feasible but only suitable in carefully selected patients.

Evidence suggests that education protects from dementia by enhancing cognitive reserve. However, this may be influenced by several socio-demographic factors. Rising numbers of dementia in India, high levels of illiteracy and heterogeneity in socio-demographic factors provide an opportunity to explore this relationship. Objective To study the association between education and age at dementia onset, in relation to socio-demographic factors. Methods Association between age at dementia onset and literacy was studied in relationship to potential confounding factors such as gender, bilingualism, place of dwelling, occupation, vascular risk factors, stroke, family history of dementia and dementia subtypes. Results Case records of 648 dementia patients diagnosed in a specialist clinic in a University hospital in Hyderabad, India were examined. All patients were prospectively enrolled as part of an ongoing longitudinal project that aims to evaluate dementia subjects with detailed clinical, etiological, imaging, and follow-up studies. Of the 648 patients, 98 (15.1%) were illiterate. More than half of illiterate skilled workers were engaged in crafts and skilled agriculture unlike literates who were in trade or clerical jobs. Mean age at onset in illiterates was 60.1 years and in literates 64.5 years (p=0.0002). Factors independently associated with age at dementia onset were bilingualism, rural dwelling and stroke, but not education. Conclusion Our study demonstrates that in India, rural dwelling, bilingualism, stroke and occupation modify the relationship between education and dementia. PMID:29213894

Osteoarthritis (OA) is one of the most common degenerative disorders among the elderly population; although aging is the most important cause, research has shown that it is a complex disease with many etiologies. It is not an inevitable part of aging but rather the result of a combination of factors, many of which can be modified or prevented. The objective of this study was to assess the burden and determinants of OA knee among the adult population. A community-based, cross-sectional study among 1986 adult persons living in a rural area in Kanchipuram district, Tamil Nadu, South India, was interviewed and examined from January 2014 to December 2014. Data collection was done by the postgraduates, trained health workers under the supervision of principal investigator. Written and informed consent was obtained before data collection. OA was diagnosed using the criteria laid down by the American College of Rheumatology, and it was validated and tested in the study area. A total of 1986 adult respondents were interviewed out of which 27.1% had OA of knee. Age more than 50 years, female gender, tobacco usage, illiteracy, lower socioeconomic class, positive family history of OA, diabetes, and hypertension were found to be associated with OA knee (P < 0.05). The burden of osteoarthritis knee was high in this region. Hence, effective preventive strategy has to be taken to minimize this burden.

Data about etiologic and demographic characteristics of acute poisoning in adults in Qatar are lacking. This prospective observational study was undertaken to analyze characteristics and possible determinants of acute poisoning in adults in Qatar. During 2010, 18,073 patients attended the emergency department of Hamad General Hospital, a teaching hospital in Qatar. Out of them, 599 (3.3%) patients were diagnosed as "poisoning case" with either chemical or pharmaceutical substances. The prevalence rate of poisoning incidence was 35.3/100,000 population. Seven patients died, corresponding with a case-fatality rate of 0.39/1000. The majority were male (65%) and the mean age was 34 years. The poisons involved were mainly chemicals (61.6%) and pharmaceuticals (38.4%). Female, mainly single, suffered more intentional poisoning compared to male. Of the patients aged 60 years and above (7.2%), the majority (95.3%) suffered unintentional poisoning with pharmaceuticals; 56% with warfarin, 12% with digoxin and 7% with insulin. Multivariate analysis shows that female gender, single status, younger than 35 years of age, being poisoned by pharmaceutical products, and the need for hospitalization are significant determinants for acute intentional poisoning after adjusting all other possible covariates. The findings of this study can be used to establish awareness and prophylactic campaigns in Qatar.

The aim of this study was to investigate the frequency and distribution of cancer cases in a defined time period in Somalia. A total of 403 cancer cases were diagnosed between January 01, 2016 and March 01, 2017 in the Department of Pathology at the Somalia Mogadishu-Turkey Education and Research Hospital or the Department of Oncology at Uniso Hospital, Somalia University. Data on cancer type, patient age, and gender were obtained from pathology reports and hospital records. Female patients totaled 49.6% (n = 200) and 50.4% of patients were male (n = 203). The youngest patient was 18 years of age, the oldest was 97, and the average age was 53.4 years. The 10 most common types of cancer were esophageal (n = 130, 32.3%), non-Hodgkin lymphoma (n = 35, 8.7%), liver (n = 26, 6.5%), breast (n = 24, 6.0%), skin (n = 17, 4.2%), thyroid (n = 13, 3.2%), brain (n = 12, 3.0%), bone (n = 11, 2.7%), colorectal (n = 11, 2.7%), and soft tissue (n = 11, 2.7%). The most common site of cancer in both males and females was the esophagus. These results show a high incidence of esophageal cancer in Somalia, and strongly suggest that environmental risk factors and nutritional habits have a strong impact in this population. Serious and extensive research on the etiology of esophageal cancer is required. Copyright © 2017 Elsevier Inc. All rights reserved.

Evaluation of environmental risk factors in the development of autism spectrum disorder (ASD) is needed for a more complete understanding of disease etiology and best approaches for prevention, diagnosis, and treatment. A pilot experiment in 54 children (n = 25 ASD, n = 29 controls; aged 12.4 ± 3.9 years) screened for 87 urinary mycotoxins via liquid chromatography-tandem mass spectrometry to assess current exposure. Zearalenone, zearalenone-4-glucoside, 3-acetyldeoxynivalenol, and altenuene were detected in 9/54 (20%) samples, most near the limit of detection. No mycotoxin/group of mycotoxins was associated with ASD-diagnosed children. To identify potential correlates of mycotoxin presence in urine, we further compared the nine subjects where a urinary mycotoxin was confirmed to the remaining 45 participants and found no difference based on the presence or absence of mycotoxin for age (t-test; p = 0.322), gender (Fisher’s exact test; p = 0.456), exposure or not to selective serotonin reuptake inhibitors (Fisher’s exact test; p = 0.367), or to other medications (Fisher’s exact test; p = 1.00). While no positive association was found, more sophisticated sample preparation techniques and instrumentation, coupled with selectivity for a smaller group of mycotoxins, could improve sensitivity and detection. Further, broadening sampling to in utero (mothers) and newborn-toddler years would cover additional exposure windows. PMID:27447670

Urinary tract infection is one of the common infections in the Indian community. Distribution and susceptibility of UTI-causing pathogens change according to time and place. This study was conducted to determine the distribution and antimicrobial susceptibility of uropathogens in the Indian community as well as to determine the effect of gender and age on the etiology of bacterial uropathogens. Clean catch midstream urine samples were collected from 288 patients of the age ranging from 15 to ≥48 years. Antimicrobial susceptibility was performed on all isolated bacteria by Kirby Bauer's disc diffusion method. The multiple antibiotic resistance (MAR) index of each antibiotic was calculated. The UTI prevalence was 53.82% in patients; however, the prevalence was significantly higher in females than in males (females: 73.57%; males: 35.14%; P = 0.000). Females within the age group of 26–36 years and elderly males of ≥48 years showed higher prevalence of UTI. Gram negative bacteria (90.32%) were found in high prevalence than Gram positive (9.68%). Escherichia coli (42.58%) was the most prevalent gram negative isolate. Nitrofurantoin (78.71%) was found the most resistant drug among all uropathogens. Tested carbapenems were found the most susceptible drug against isolated uropathogens which showed 92.26% and 84.52% susceptibility, respectively. PMID:24288649

Long-term outcome of burn scars as well as the relation with clinically relevant parameters has not been studied quantitatively. Therefore, we conducted a detailed analysis on the clinical changes of burn scars in a longitudinal setup. In addition, we focused on the differences in scar quality in relation to the depth, etiology of the burn wound and age of the patient. Burn scars of 474 patients were subjected to a scar assessment protocol 3, 6, and 12 months postburn. Three different age groups were defined (≤5, 5-18, and ≥18 years). The observer part of the patient and observer scar assessment scale revealed a significant (p < 0.001) improvement in scar quality at 12 months compared with the 3- and 6-month data. Predictors for severe scarring are depth of the wound (p < 0.001) and total body surface area burned (p < 0.001). Etiology (p = 0.753) and age (p > 0.230) have no significant influence on scar quality when corrected for sex, total body surface area burned, time, and age or etiology, respectively. © 2012 by the Wound Healing Society.

The MATRICS Consensus Cognitive Battery (MCCB) was administered to 293 schizophrenia outpatients and 210 community residents in Spain. Our first objective was to identify the age- and gender-corrected MCCB cognitive profile of patients with schizophrenia. The profile of schizophrenia patients showed deficits when compared to controls across the seven MCCB domains. Reasoning and Problem Solving and Social Cognition were the least impaired, while Visual Learning and Verbal Learning showed the greatest deficits. Our second objective was to study the effects on cognitive functioning of age and gender, in addition to diagnosis. Diagnosis was found to have the greatest effect on cognition (Cohen's d>0.8 for all MCCB domains); age and gender also had effects on cognitive functioning, although to a lesser degree (with age usually having slightly larger effects than gender). The effects of age were apparent in all domains (with better performance in younger subjects), except for Social Cognition. Gender had effects on Attention/Vigilance, Working Memory, Reasoning and Problem Solving (better performance in males), and Social Cognition (better performance in females). No interaction effects were found between diagnosis and age, or between diagnosis and gender. This lack of interactions suggests that age and gender effects are not different in patients and controls. Copyright © 2015 Elsevier B.V. All rights reserved.

Data showing a remarkable gender difference in life expectancy and mortality, including survival to extreme age, are reviewed starting from clinical and demographic data and stressing the importance of a comprehensive historical perspective and a gene-environment/lifestyle interaction. Gender difference regarding prevalence and incidence of the most important age-related diseases, such as cardiovascular and neurodegenerative diseases, cancer, Type 2 diabetes, disability, autoimmunity and infections, are reviewed and updated with particular attention to the role of the immune system and immunosenescence. On the whole, gender differences appear to be pervasive and still poorly considered and investigated despite their biomedical relevance. The basic biological mechanisms responsible for gender differences in aging and longevity are quite complex and still poorly understood. The present review focuses on centenarians and their offspring as a model of healthy aging and summarizes available knowledge on three basic biological phenomena, i.e. age-related X chromosome inactivation skewing, gut microbiome changes and maternally inherited mitochondrial DNA genetic variants. In conclusion, an appropriate gender-specific medicine approach is urgently needed and should be systematically pursued in studies on healthy aging, longevity and age-related diseases, in a globalized world characterized by great gender differences which have a high impact on health and diseases. © 2016 The Author(s).

Age- and gender-related alterations of hemorheological parameters have not been completely elucidated to date. Experiments on older animals may give valuable information on this issue. However, the majority of rheological studies have been performed in young rodents. We aimed to investigate the influence of aging and gender on hemorheological parameters in rats. Coeval male (n=10) and female (n=10) Wistar (Crl:WI) rats were followed-up over 15 months. Blood samples were obtained from the lateral tail vein at 3, 4, 5, 9, 12, 15 and 18 months of age. Hematological parameters, red blood cell deformability (elongation under shear), osmotic gradient deformability and erythrocyte aggregation were tested. Body weight and the estrus cycle (in females) were also examined. Erythrocyte aggregation showed age- and gender-related variations. Red blood cell deformability was greater in females and gradually decreased over the 15-month period in both genders. Erythrocyte aggregation was greater in male rats at most ages, but did not show consistent changes with age. The micro-rheological parameters showed age-related alterations with gender differences. The effect of the estrous cycle cannot be excluded in female rats. The results provide reference data for studies of aging in rats and of the mechanism related to age and gender differences in hemorheology.

The etiology of gender identity disorder (GID) remains largely unknown. In recent literature, increased attention has been attributed to possible biological factors in addition to psychological variables. To review the current literature on case studies of twins concordant or discordant for GID. A systematic, comprehensive literature review. Of 23 monozygotic female and male twins, nine (39.1%) were concordant for GID; in contrast, none of the 21 same-sex dizygotic female and male twins were concordant for GID, a statistically significant difference (P=0.005). Of the seven opposite-sex twins, all were discordant for GID. These findings suggest a role for genetic factors in the development of GID. © 2011 International Society for Sexual Medicine.

Research and theorizing on gender and age differences in self-esteem have played a prominent role in psychology over the past 20 years. However, virtually all empirical research has been undertaken in the United States or other Western industrialized countries, providing a narrow empirical base from which to draw conclusions and develop theory. To broaden the empirical base, the present research uses a large Internet sample (N = 985,937) to provide the first large-scale systematic cross-cultural examination of gender and age differences in self-esteem. Across 48 nations, and consistent with previous research, we found age-related increases in self-esteem from late adolescence to middle adulthood and significant gender gaps, with males consistently reporting higher self-esteem than females. Despite these broad cross-cultural similarities, the cultures differed significantly in the magnitude of gender, age, and Gender × Age effects on self-esteem. These differences were associated with cultural differences in socioeconomic, sociodemographic, gender-equality, and cultural value indicators. Discussion focuses on the theoretical implications of cross-cultural research on self-esteem. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Gender differences in autobiographical memory emerge in some data collection paradigms and not others. The present study included an extensive analysis of gender differences in autobiographical narratives. Data were collected from 196 participants, evenly split by gender and by age group (emerging adults, ages 18-29, and young adults, ages 30-40). Each participant reported four narratives, including an event that had occurred in the last 2 years, a high point, a low point, and a self-defining memory. Additionally, all participants completed self-report measures of masculine and feminine gender typicality. The narratives were coded along six dimensions-namely coherence, connectedness, agency, affect, factual elaboration, and interpretive elaboration. The results indicated that females expressed more affect, connection, and factual elaboration than males across all narratives, and that feminine typicality predicted increased connectedness in narratives. Masculine typicality predicted higher agency, lower connectedness, and lower affect, but only for some narratives and not others. These findings support an approach that views autobiographical reminiscing as a feminine-typed activity and that identifies gender differences as being linked to categorical gender, but also to one's feminine gender typicality, whereas the influences of masculine gender typicality were more context-dependent. We suggest that implicit gendered socialization and more explicit gender typicality each contribute to gendered autobiographies.

Background Intellectual disability (ID), characterized by impairments in intellectual function and adaptive behavior, affects 1-3% of the population. Many studies investigated its etiology, but few are cohort studies in middle-income countries. Aims To estimate prevalence, etiology, and factors related to ID among children prospectively followed since birth in a Southern Brazilian city (Pelotas). Methods In 2004, maternity hospitals were visited daily and births were identified. Live-born infants (n = 4,231) whose family lived in the urban area have been followed for several years. At the age of 2 and 4 years, performances in development and intelligence tests were evaluated using the Battelle Developmental Inventory and Wechsler Intelligence Scale, respectively. Children considered as having developmental delay were invited to attend a genetic evaluation. Results At 4 years of age, the prevalence of ID was 4.5%, and the etiology was classified into 5 groups: environmental (44.4%), genetic (20.5%), idiopathic (12.6%), neonatal sequelae (13.2%), other diseases (9.3%). Most children presented impairment in two or more areas of adaptive behavior. There was no difference in prenatal care attendance or maternal schooling among the groups. Conclusion For about 40% of children, ID was attributed to nonbiological factors, suggesting that the rate may be reduced with appropriate interventions early in life. PMID:27595410

Studies using relative measures, such as standardized mortality ratios, have shown that patients with epilepsy have an increased mortality. Reports on more direct and absolute measure such as life expectancy are sparse. We report potential years lost and how life expectancy has changed over 40 years in a cohort of patients with newly diagnosed epilepsy. We analyzed life expectancy in a cohort of adult patients diagnosed with definite epilepsy between 1970 and 2010. Those with brain tumor as cause of epilepsy were excluded. By retrospective probabilistic record linkage, living or death status was derived from the national death registry. We estimated life expectancy by a Weibull regression model using gender, age at diagnosis, epilepsy etiology, and year of diagnosis as covariates at time of epilepsy diagnosis, and 5, 10, 15, and 20 years after diagnosis. Results were compared to the general population, and 95% confidence intervals are given. There were 249 deaths (105 women, age at death 19.0-104.0 years) in 1,112 patients (11,978.4 person-years, 474 women, 638 men). A substantial decrease in life expectancy was observed for only a few subgroups, strongly depending on epilepsy etiology and time of diagnosis: time of life lost was highest in patients with symptomatic epilepsy diagnosed between 1970 and 1980; the impact declined with increasing time from diagnosis. Over half of the analyzed subgroups did not differ significantly from the general population. This effect was reversed in the later decades, and life expectancy was prolonged in some subgroups, reaching a maximum in those with newly diagnosed idiopathic and cryptogenic epilepsy between 2001 and 2010. Life expectancy is reduced in symptomatic epilepsies. However, in other subgroups, a prolonged life expectancy was found, which has not been reported previously. Reasons may be manifold and call for further study. © 2017 The Authors. Epilepsia published by Wiley Periodicals, Inc. on behalf of International League Against Epilepsy.

Attachment security as a mechanism linking foster care placement to improved mental health outcomes in previously institutionalized children

McLaughlin, Katie A.; Zeanah, Charles H.; Fox, Nathan A.; Nelson, Charles A.

2011-01-01

Background Children reared in institutions experience elevated rates of psychiatric disorders. Inability to form a secure attachment relationship to a primary caregiver is posited to be a central mechanism in this association. We determined whether the ameliorative effect of a foster care (FC) intervention on internalizing disorders in previously institutionalized children was explained by the development of secure attachment among children placed in FC and evaluated the role of lack of attachment in an institutionalized sample on the etiology of internalizing disorders within the context of a randomized trial. Methods A sample of 136 children (aged 6-30 months) residing in institutions was recruited in Bucharest, Romania. Children were randomized to FC (n=68) or to care as usual (CAU; n=68). Foster parents were recruited, trained, and overseen by the investigative team. Attachment security at 42 months was assessed using the Strange Situation Procedure, and internalizing disorders at 54 months were assessed using the Preschool Age Psychiatric Assessment. Results Girls in FC had fewer internalizing disorders than girls in CAU (OR=0.17, p=006). The intervention had no effect on internalizing disorders in boys (OR=0.47, p=.150). At 42 months, girls in FC were more likely to have secure attachment than girls in CAU (OR=12.5, p<.001), but no difference was observed in boys (OR=2.0, p=.205). Greater attachment security predicted lower rates of internalizing disorders in both sexes. Development of attachment security fully mediated intervention effects on internalizing disorders in girls. Conclusion Placement into FC facilitated the development of secure attachment and prevented the onset of internalizing disorders in institutionalized girls. The differential effects of FC on attachment security in boys and girls explained gender differences in the intervention effects on psychopathology. Findings provide evidence for the critical role of disrupted attachment in the etiology of internalizing disorders in children exposed to institutionalization. PMID:21733136

Objective This study examined the attribution of MCI etiology assigned by individuals with MCI and their care-partners, and the extent to which the dyads agreed on the attribution of MCI etiology. Methods We conducted secondary analyses of cross-sectional data from a cohort of individuals with MCI (n=60) and their care-partners (n=60). The mean age of the individuals with MCI was 71.0±9.4 and of care-partners 64.2±11.0 years. The primary outcome was attribution assigned to memory deficits on the Illness Perception Questionnaire. We categorized the attribution of MCI etiology as either potentially controllable or uncontrollable factors. We described the distribution of MCI etiology with descriptive and contingency tables. We determined the odds of a patient or care-partner choosing one type of MCI etiology over another. Results Although individuals with MCI and their care-partners most frequently attributed MCI to uncontrollable factors (81.7% and 61.0%, respectively), care-partners were 28.41 [95% CI, 1.26 to 645.48] times more likely to attribute MCI etiology to potentially controllable factors than individuals with MCI. No significant associations between demographic factors and attribution of MCI etiology were found for the individuals with MCI or the care-partners. Conclusion Findings demonstrated that members of the dyad attributed MCI etiology to different causes. Attributions of MCI etiology should be explored by professionals to clarify misconceptions and potentially improve subsequent voluntary actions intended to assist oneself or others. PMID:24123240

Lower urinary tract symptoms (LUTS) in young women is becoming a more recognized urologic issue that can arise from many causes, each with their own management strategy. The purpose of this study was to determine the rates of various etiologies for LUTS in women under 40 years of age. Video urodynamic studies (VUDS) were performed in 70 women age 40 years or less with LUTS for greater than 6 months between March 2005 and June 2012 at Weill Cornell Medical College. Patients with culture-proven bacterial urinary tract infections, pelvic organ prolapse greater than grade I, symptoms for less than 6 months, a history of neurologic disease, or previous urological surgery affecting voiding function, were excluded from the analysis. The mean age of the patients was 31.95 ± 5.57. There were 48 patients that presented with more than one urinary symptom (68.57%). The most frequent complaints included: urinary frequency (n = 42, 34.15%), incontinence (n = 26, 21.14%), and urinary urgency (n = 22, 17.89%). The most common urodynamic abnormality was dysfunctional voiding (n = 25, 28.74%), detrusor overactivity (n = 15, 20.00%), bladder outlet obstruction (n = 8, 11.43%). There were no significant differences seen in complaints or AUA symptom and quality of life scores across diagnosis groups. Persistent LUTS can present in younger women with an unclear etiology, which may be characterized using VUDS. The most common etiology found is dysfunctional voiding followed by detrusor overactivity. This study shows that the etiology can be more accurately determined using VUDs, which can assist in management.

This study investigated whether there is an association between semiology of status epilepticus (SE) and response to treatment and outcome. Two hundred ninety-eight consecutive adult patients (160 females, 138 males) with SE at the University of Munich Hospital were prospectively enrolled. Mean age was 63.2±17.5 (18-97) years. Patient demographics, SE semiology and electroencephalography (EEG) findings, etiology, duration of SE, treatment, and outcome measures were investigated. Status epilepticus semiology was classified according to a semiological status classification. Patient's short-term outcome was determined by Glasgow Outcome Scale (GOS). The most frequent SE type was nonconvulsive SE (NCSE) (39.2%), mostly associated with cerebrovascular etiology (46.6%). A potentially fatal etiology was found in 34.8% of the patients. More than half (60.7%) of the patients had poor short-term outcome (GOS≤3) with an overall mortality of 12.4%. SE was refractory to treatment in 21.5% of the patients. Older age, potentially fatal etiology, systemic infections, NCSE in coma, refractory SE, treatment with anesthetics, long SE duration (>24h), low Glasgow Coma Scale (GCS) (≤8) at onset, and high Status Epilepticus Severity Score (STESS-3) (≥3) were associated with poor short-term outcome and death (p<0.05). Potentially fatal etiology and low GCS were the strongest predictors of poor outcome (Exp [b]: 4.74 and 4.10 respectively, p<0.05). Status epilepticus semiology has no independent association with outcome, but potentially fatal etiology and low GCS were strong predictive factors for poor short-term outcome of SE.

Members of the genera Alphavirus (family Togaviridae ) and Flavivirus (family Flaviridae ) are important zoonotic human and equine etiologic agents of neurologic diseases in the New World. In 2010, an outbreak of Madariaga virus (MADV; formerly eastern equine encephalitis virus) and Venezuelan equine encephalitis virus (VEEV) infections was reported in eastern Panamá. We further characterized the epidemiology of the outbreak by studying household contacts of confirmed human cases and of equine cases with neurological disease signs. Serum samples were screened using a hemagglutination inhibition test, and human results were confirmed using plaque reduction neutralization tests. A generalized linear model was used to evaluate the human MADV and VEEV seroprevalence ratios by age (in tercile) and gender. Overall, antibody prevalence for human MADV infection was 19.4%, VEEV 33.3%, and Mayaro virus 1.4%. In comparison with individuals aged 2-20 years, people from older age groups (21-41 and > 41 years) were five times more likely to have antibodies against VEEV, whereas the MADV prevalence ratio was independent of age. The overall seroprevalence of MADV in equids was 26.3%, VEEV 29.4%, West Nile virus (WNV) 2.6%, and St. Louis encephalitis virus (SLEV) was 63.0%. Taken together, our results suggest that multiple arboviruses are circulating in human and equine populations in Panamá. Our findings of a lack of increase in the seroprevalence ratio with age support the hypothesis of recent MADV exposure to people living in the affected region.

The aim of this study is to identify common causes, associated ophthalmological abnormalities, and systemic comorbidities in children in Andhra Pradesh, India, with cerebral visual impairment (CVI). A retrospective review of case records of all children aged <16 years with diagnosis of CVI seen between January 2016 and December 2016 was carried out. Data were collected for their age, gender, cause of CVI, refraction, accommodation, anterior and posterior segment examination findings, and systemic problems. A total of 124 patients were identified and studied (80 boys and 44 girls, mean age 5.23 years, 44.8% aged <2 years). The most common causes of CVI were hypoxic-ischemic encephalopathy (HIE) (34.4%), undetermined etiology (32.8%), neonatal seizures, and infantile spasms (16% each). The most common presenting complaints were poor vision (76%) and squint (11.2%). Profound visual impairment was seen in 88.8%, and 11.2% had high functioning CVI. Fifty-eight (46.4%) patients had significant refractive errors, 40 (32.25%) had strabismus, 4 (3.2%) had visually significant cataract, and 40 (32%) had optic atrophy. Motor delay was observed in 39.5%, speech delay was evident in 22.4%, and cognitive delay in 16%. HIE is the most common cause (one-third) of CVI in our population, and the majority of them presented at age <2 years (44.8%) with profound visual impairment (88.8%). A significant number of them have treatable ophthalmic conditions such as refractive errors (46.4%), accommodative insufficiency (12.1%), and cataract (3.2%), and more than one-third of them also have delay in other areas of development.

"It's your badge of inclusion": the Red Hat Society as a gendered subculture of aging.

Although studies document the health-enhancing effects of social engagement, they reveal little about the underlying mechanisms operating within specific organizational contexts. Limited attention is given to the role of inequality--particularly age and gender--in shaping either the organizations to which we belong or their consequences for our well-being. We address this issue by examining the Red Hat Society, a social organization for middle-aged and older women. Interviews with members (n=52) illustrate how age and gender inequality interact to shape the organization, which can be viewed as a gendered subculture of aging. Drawing on this framework, we discuss four processes through which participation generates benefits for older women involved in age- and gender-segregated organizations: enhancing social networks, countering invisibility, creating positive frames for aging experiences, and promoting youthful identities.

The most commonly impacted tooth in the oral cavity is the mandibular third molar. Various etiologic factors have been suggested for impacted mandibular third molars. The pattern and prevalence of impacted mandibular third molars vary with different population and region. This study throws light on the prevalence and pattern of impacted mandibular third molars in Eritrea, East Africa. This is the first reported study regarding the same from Eritrea. To assess the prevalence and pattern of impacted mandibu-lar third molars in the population of Eritrea, East Africa by conducting a retrospective study from January 2009 to January 2014. This study was conducted in the Department of Oral and Maxillofacial Surgery, Orotta School of Medicine and Dental Medicine and the Orotta Referral Medical and Surgical Hospital, Asmara, Eritrea. A total of 1,813 clinical and radiographic records [orthopantomograms] were assessed and 276 cases were selected for the study as per the inclusion criteria. They were evaluated for the frequency among the various age groups, gender and region along with the sides affected, angulation and level of impaction. The presence of systemic conditions and associated pathologies was also assessed according to the type of impaction. The average age of these patients in the study was found to be 30 years, with the 20 to 30 years age group being the most affected (67.4%). Females (53.3%) were affected more than the males (46.7%). People from the Asmara region showed significantly more prevalence (79.7%) than the adjoining areas (20.3%). Mesioangular impaction was the most common angulation with a definite relationship to the age groups (p = 0.032). The level of impaction had no significant relationship to the age groups, gender, or region, although class I position A was found to be the most common type. Mesioangular class I position A impac-tion showed an apparent relationship with underlying systemic conditions, but it was statistically insignificant. Mesioangular impaction was found to be associated with the most number of pathologies (p = 0.001). The prevalence of mandibular impaction was less in Eritrea (15.2%) compared with other populations. This study provides useful baseline data for the prevalence and pattern of mandibular impaction in the Eritrean population. This study throws light on the pattern, type, and frequency of mandibular impacted teeth as per age, sex, and region among the population of Eritrea.

As societies age and governments attempt to manage within constrained health budgets by moving care into community settings, women will be called upon to provide more palliative care in old age. However, little is known about gendered disparities for caregivers of people over the age of 65 years. To identify and synthesise the empirical literature between 1994 and 2014 that focusses on gender and family caregiving for people over the age of 65 years with a life-limiting illness. Systematic review of qualitative and quantitative studies conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Supplemental review using a novel feminist quality appraisal framework. Search of MEDLINE, CINAHL, PsycINFO, Sociological Abstracts and Gender Studies to find empirical studies on gender and family caregiving at end-of-life in the context of old age. Of 19 studies identified, 9 presented thorough gender analyses. Gender themes included why people care, how they care, and the consequences of providing care. Women caregivers experienced a greater degree of mental and physical strain than their male counterparts. This was linked to societal expectation that women should provide a greater degree of care at the end-of-life for family members. Palliative family caregiving for older adults is gendered. Gender affects why people care and the consequences of providing care. Palliative care literature needs to incorporate a greater gender focus for future research and policy makers need to be aware of the gendered ramifications of providing more palliative care in the community. © The Author(s) 2016.

To identify differences in the characteristics of patients with diabetic foot ulcers (DFUs) according to their etiological classification and to compare their healing time. Over a 4.5-year period, 73 patients with DFUs were recruited. DFUs were etiologically classified as being of neuropathic, ischemic, or neuro-ischemic origin. Descriptive analyses were performed to characterize study subjects, foot-related factors, and healing outcome and time. Duration of healing was assessed using the Kaplan-Meier method. Healing time among the three types was compared using the log rank test. The number of patients manifesting neuropathic, ischemic, and neuro-ischemic ulcers was 30, 20, and 14, respectively. Differences were identified for age, diabetes duration, body mass index, hypertension, and estimated glomerular filtration rate. Patients with neuro-ischemic ulcers had better ankle-brachial index, skin perfusion pressure (SPP), and transcutaneous oxygen pressure values compared to those with ischemic ulcers. The average time in which 50% of patients had healed wounds was 70, 113, and 233 days for neuropathic, neuro-ischemic, and ischemic ulcers, respectively. Main factors associated with healing were age and SPP values. Based on the etiological ulcer type, DFU healing course and several patient factors differed. Failure to consider the differences in DFU etiology may have led to heterogeneity of results in previous studies on DFUs. Copyright © 2014 Elsevier Inc. All rights reserved.

Fertility Decline, Gender Composition of Families, and Expectations of Old Age Support.

PubMed

Allendorf, Keera

2015-08-01

Recent fertility declines in non-Western countries may have the potential to transform gender systems. One pathway for such transformations is the creation of substantial proportions of families with children of only one gender. Such families, particularly those with only daughters, may facilitate greater symmetry between sons and daughters. This article explores whether such shifts may influence gendered expectations of old age support. In keeping with patriarchal family systems, old age support is customarily provided by sons, but not daughters, in India. Using data from the 2005 Indian Human Development Survey, I find that women with sons overwhelmingly expect old age support from a son. By contrast, women with only daughters largely expect support from a daughter or a source besides a child. These findings suggest that fertility decline may place demographic pressure on gendered patterns of old age support and the gender system more broadly.

This study investigated the participation and performance trends as well as the age and gender interaction at the Olympic distance 'Zürich Triathlon' (1.5 km swim, 40 km cycle and 10 km run) from 2000 to 2010 in 7,939 total finishers (1,666 females and 6,273 males). Female triathletes aged from 40 to 54 years significantly (P < 0.05) increased their participation while the participation of younger females and males remained stable. Males of 50-54 years of age and females of 45-49 years of age improved their total race time. For elite top five overall triathletes, mean gender differences in swimming, cycling, running and overall race time were 15.2 ± 4.6%, 13.4 ± 2.3%, 17.1 ± 2.5%, and 14.8 ± 1.8%, respectively. For both elite and age group athletes, the gender difference in cycling time was significantly (P <0.001) lower than for swimming and running. The gender difference in overall Olympic distance triathlon performance increased after the age of 35 years, which appeared earlier compared to long distance triathlon as suggested by previous studies. Future investigations should compare gender difference in performance for different endurance events across age to confirm a possible effect of exercise duration on gender difference with advancing age.

2007-01-01

In science, theories lend coherence to vast amounts of descriptive information. However, current diagnostic approaches in psychopathology are primarily atheoretical, emphasizing description over etiological mechanisms. We describe the importance of Polyvagal Theory toward understanding the etiology of emotion dysregulation, a hallmark of psychopathology. When combined with theories of social reinforcement and motivation, Polyvagal Theory specifies etiological mechanisms through which distinct patterns of psychopathology emerge. In this paper, we summarize three studies evaluating autonomic nervous system functioning in children with conduct problems, ages 4-18. At all age ranges, these children exhibit attenuated sympathetic nervous system responses to reward, suggesting deficiencies in approach motivation. By middle school, this reward insensitivity is met with inadequate vagal modulation of cardiac output, suggesting additional deficiencies in emotion regulation. We propose a biosocial developmental model of conduct problems in which inherited impulsivity is amplified through social reinforcement of emotional lability. Implications for early intervention are discussed. PMID:17045726

Challenging cisgenderism in the ageing and aged care sector: Meeting the needs of older people of trans and/or non-binary experience.

PubMed

Recent Australian legislative and policy changes can benefit people of trans and/or non-binary experience (e.g. men assigned female with stereotypically 'female' bodies, women assigned male with stereotypically 'male' bodies, and people who identify as genderqueer, agender [having no gender], bi-gender [having two genders] or another gender option). These populations often experience cisgenderism, which previous research defined as 'the ideology that invalidates people's own understanding of their genders and bodies'. Some documented forms of cisgenderism include pathologising (treating people's genders and bodies as disordered) and misgendering (disregarding people's own understanding and classifications of their genders and bodies). This system of classifying people's lived experiences of gender and body invalidation is called the cisgenderism framework. Applying the cisgenderism framework in the ageing and aged care sector can enhance service providers' ability to meet the needs of older people of trans and/or non-binary experience. © 2015 AJA Inc.

Hyperpigmentations are disorders displayed with a change in the color of the skin, its strange shape, the lack of symmetry, and irregular placement. They appear no matter on the age, gender, and often as a congenital defect. Disorder connected with overproduction of melanin by pigmentary cells. The change of color is due to endogenous and exogenous cause. The aim of this thesis was to conduct a research in vivo. This will allow to judge the effectiveness of the cosmetic product which brightens the skin with hyperpigmentation problems. The characteristics of dermocosmetics were tested on people with various etiology of hyperpigmentation. The aim of the research was to assess the effect of the active substances used daily on skin hyperpigmentation. The tests were carried out on groups of patients with hyperpigmentations. The application of the pharmaceutical and the use of specific apparatus measurements were taken on every medical checkup. A survey was conducted to assess the changes in the face, neck, and neckline skin. The research was based on the apparatus analysis of the skin condition (MPA ® , VISIA ® ). Regular application of the pharmaceutical caused brightening of hyperpigmentations (P < 0.05). General improvement in skin condition was also observed - the increase in skin elasticity, smoothness, and the enhancement of hydration levels. Dermocosmetics for people with hyperpigmentation are an essential part of their medical treatment. In case of epidermal hyperpigmentation, the recipe of individually chosen and tested combination of ingredients enables us to reach satisfactory results. © 2016 Wiley Periodicals, Inc.

2003-05-15

This study investigated the effect of chronic low back pain, age, gender, and time of measurement on the magnitude of vertical spinal creep (VSC) and its recovery. A mixed design, involving three independent variables (chronic low back pain, age, and gender) and one repeated variable (time), was used. One hundred and six subjects of both genders, with and without chronic low back pain, aged between 20 and 60 years, participated in the study. The measurement of VSC and its recovery was performed using a seated stadiometer that allowed continuous measurement of VSC without changing the subject's posture over 25 min. Unloaded VSC was measured during the initial 5 min, followed by 10 min with an additional load of 15% of the subject's body weight and then for a further 10 min after the removal of the load. Subjects were grouped into one of eight categories according to the presence of chronic low back pain, age (20-39 years or 40-60 years) and gender. Repeated measures analysis of variance was computed. A significant increase in VSC with time of measurement was observed (p<0.001). No significant main effects for chronic low back pain, age, or gender were found at any time during the 25-min VSC testing protocol. Significant interactions were found between age and gender during the loaded (p=0.02) and unloaded (p=0.02) phases. A significant interaction was found between chronic low back pain and gender at the end of the unloaded phase (p=0.04). These findings suggest a combined influence of chronic low back pain, age, and gender on VSC and its recovery and that the dominance of each variable changed with the time of the measurement. Thus, subjects who differ in the presence of chronic low back pain, age, and gender should not be combined for statistical analysis of VSC and its recovery.

The purpose of this study was to examine biological and behavioral explanations for gender differences in leukocyte telomere length (LTL), a biomarker of cell aging that has been hypothesized to contribute to women’s greater longevity. Data are from a subsample (n = 851) of the Multi-Ethnic Study of Atherosclerosis, a population-based study of women and men aged 45 to 84. Mediation models were used to examine study hypotheses. We found that women had longer LTL than men, but the gender difference was smaller at older ages. Gender differences in smoking and processed meat consumption partially mediated gender differences in telomere length, whereas gender differences in estradiol, total testosterone, oxidative stress, and body mass index did not. Neither behavioral nor biological factors explained why the gender difference in LTL was smaller at older ages. Longitudinal studies are needed to assess gender differences in the rate of change in LTL over time; to identify the biological, behavioral, and psychosocial factors that contribute to these differences throughout the life course; and to determine whether gender differences in LTL explain the gender gap in longevity.

Emotion processing, supported by frontolimbic circuitry known to be sensitive to the effects of aging, is a relatively understudied cognitive-emotional domain in geriatric depression. Some evidence suggests that the neurophysiological disruption observed in emotion processing among adults with major depressive disorder (MDD) may be modulated by both gender and age. Therefore, the present study investigated the effects of gender and age on the neural circuitry supporting emotion processing in MDD. Cross-sectional comparison of fMRI signal during performance of an emotion processing task. Outpatient university setting. One hundred adults recruited by MDD status, gender, and age. Participants underwent fMRI while completing the Facial Emotion Perception Test. They viewed photographs of faces and categorized the emotion perceived. Contrast for fMRI was of face perception minus animal identification blocks. Effects of depression were observed in precuneus and effects of age in a number of frontolimbic regions. Three-way interactions were present between MDD status, gender, and age in regions pertinent to emotion processing, including frontal, limbic, and basal ganglia. Young women with MDD and older men with MDD exhibited hyperactivation in these regions compared with their respective same-gender healthy comparison (HC) counterparts. In contrast, older women and younger men with MDD exhibited hypoactivation compared to their respective same-gender HC counterparts. This the first study to report gender- and age-specific differences in emotion processing circuitry in MDD. Gender-differential mechanisms may underlie cognitive-emotional disruption in older adults with MDD. The present findings have implications for improved probes into the heterogeneity of the MDD syndrome. Copyright © 2015 American Association for Geriatric Psychiatry. Published by Elsevier Inc.

The etiology of musculoskeletal disorders is complex, with physical and psychosocial working conditions playing an important role. This study aimed to determine the relationship between psychosocial work conditions, such as psychological job demands, decision latitude, social support and job insecurity and musculoskeletal complains (MSCs) and (repetitive strain injuries (RSIs) in a 1-year prospective study. The job content questionnaire, the Nordic musculoskeletal questionnaire and provocation tests were used to study 725 employees aged 20-70 years. Pain in the lower back (58 % of subjects), neck (57 %), wrists/hands (47 %) and upper back (44 %) was most frequent. The carpal tunnel syndrome (CTS) (33.6 %), rotator cuff tendinitis (15.4 %), Guyon's canal syndrome (13.4 %), lateral epicondylitis (7.6 %), medial epicondylitis (5.3 %), tendinitis of forearm-wrist extensors (7.8 %) and tendinitis of forearm-wrist flexors (7.3 %) were the most frequent RSIs. Logistic analysis showed that increased psychological job demands statistically significantly increased the probability of lateral and medial epicondylitis, and increased control (decision latitude) statistically significantly decreased the risk of CTS. There was no relationship between job insecurity, social support and the studied RSIs. Psychosocial factors at work predict prevalence of MSCs and RSIs, irrespectively of demographic factors, e.g., age or gender, and organizational and physical factors.

In patients with functional upper gastrointestinal disorders such as gastroesophageal reflux disease and functional dyspepsia, the presence of symptoms is thought to occur in the absence of any organic diseases and the mechanisms behind this remain unclear. We therefore examined the relationship between stomach-related biomarker levels and symptoms. Twenty-four outpatients who had taken proton-pump inhibitors every day were enrolled in this study. The subjects consumed yogurt containing 109 colony-forming units of Lactobacillus gasseri OLL2716 (LG21) every day for three months. They underwent four clinical examinations in total. Each examination consisted of answering a questionnaire with a frequency scale for the symptoms of GERD (FSSG), and included measurements of the serum gastrin, ghrelin, and pepsinogens I and II levels. As a result, the FSSG score and the PGI value showed a decrease and an increase, respectively, after LG21 treatment when analyzed without age adjustment. A multiple regression analysis with additional adjustments for gender and age revealed a strong association between the PGI value and the FSSG symptom scores. Therefore either the PGI level itself or the factors regulating the PGI level might be involved in the etiology of these symptoms. PMID:24967535

Cardiac allograft vasculopathy (CAV) is a significant factor impacting outcomes after heart transplant. We performed a systematic review of risk factors for the development of CAV. A search of electronic databases was performed. The eligibility criteria included cohort and case-control studies with more than 50 adult patients submitted to a heart transplant. The outcome should be CAV diagnosed by angiography and/or intravascular ultrasound (IVUS). Two reviewers performed study selection, data abstraction, and quality assessment. Of 2514 citations, 66 articles were included--46 had 200 participants or less; 61 were single-center; and 44 were retrospective cohorts. The most used definition of CAV using angiography was the detection of any degree of abnormality (21 studies of 58). In studies using IVUS, an intimal thickness ≥0.5 mm was the most used definition (five of eight studies). Quality assessment revealed an inadequate description of patient selection, attrition, and accounting of potential confounders. Donor age, recipient age, recipient gender, etiology of heart failure, ischemic time, human leukocyte antigen matching, cytomegalovirus, lipid profile, and rejection episodes were the most studied factors. Our review indicates that the current evidence is not consistent across different studies. The definite contribution of risk factors for the development of CAV is still to be determined. © 2011 John Wiley & Sons A/S.

To determine the prognosis factors in Mexican patients with Bell's palsy. We designed a prospective, longitudinal, descriptive, and observational analysis. Two hundred and fifty one patients diagnosed with Bell's palsy at the National Institute of Rehabilitation were included. We studied the sociodemographic characteristics, seasonal occurrence, sidedness, symptoms, and therapeutic options to determine the prognostic factors for their recovery. Thirty-nine percent of patients had a complete recovery and 41.5% had an incomplete recovery. Marital status, gender, etiology, symptoms, sidedness, House-Brackmann grade, and treatments did not represent significant prognostic factors for recovery. Age > 40 years (OR = 2.4, IC 95% 1.3-4.3, p = 0.002) and lack of physical therapy (OR = 6.4, IC 95% 1.4-29.6, p = 0.006) were significant prognostic factors for incomplete recovery. Familial palsy resulted to be a protective prognostic factor against an incomplete recovery (OR = 0.54, IC 95% 0.28-1.01, p = 0.039). This protection factor was only significant in female patients (OR = 0.41, p = 0.22) but not in male patients (OR = 1.0, p = 0.61). The proportion of cases with incomplete recovery was high. The age > 40 years and lack of physical therapy were the only significant prognostic factors for an incomplete recovery.

Understanding the blood pressure (BP) distribution within populations is fundamental to an understanding of the etiology of cardiovascular diseases and to develop effective preventive strategies. This study focuses on whether the BP levels and hypertension prevalence differ between neo-migrants and settled-migrants in the city of Delhi. Data on BP, anthropometry, social variables, and demographic variables were collected from a cross-sectional sample of 226 settled-migrants and 227 neo-migrants. Men possessed significantly higher BP levels than women. Settled-migrants possessed higher BP levels, except diastolic BP in males. The prevalence of hypertension ranges from 15% (neo-migrant women) to 25% (settled-migrant men), with no significant gender differences. Group differences were significant for men. Hypertension was more prevalent in older settled-migrants and younger neo-migrants. Recent migration was found to be a significant contributor to hypertension prevalence. Age contributed significantly to BP variation in both groups except in neo-migrant men. Pulse rate also contributed to systolic BP among neo-migrant women and settled-migrant men. Thus, urban residence and migration to urban areas can be a leading cause of increased prevalence of hypertension. Neo-migrants were subjected to more lifestyle insults and the stress generated during the adjustment process may be contributing to rise of BP even at younger ages.

Objectives. We examined sexual orientation differences in adolescent smoking and intersections with race/ethnicity, gender, and age. Methods. We pooled Youth Risk Behavior Survey data collected in 2005 and 2007 from 14 jurisdictions; the analytic sample comprised observations from 13 of those jurisdictions (n = 64 397). We compared smoking behaviors of sexual minorities and heterosexuals on 2 dimensions of sexual orientation: identity (heterosexual, gay–lesbian, bisexual, unsure) and gender of lifetime sexual partners (only opposite sex, only same sex, or both sexes). Multivariable regressions examined whether race/ethnicity, gender, and age modified sexual orientation differences in smoking. Results. Sexual minorities smoked more than heterosexuals. Disparities varied by sexual orientation dimension: they were larger when we compared adolescents by identity rather than gender of sexual partners. In some instances race/ethnicity, gender, and age modified smoking disparities: Black lesbians–gays, Asian American and Pacific Islander lesbians–gays and bisexuals, younger bisexuals, and bisexual girls had greater risk. Conclusions. Sexual orientation, race/ethnicity, gender, and age should be considered in research and practice to better understand and reduce disparities in adolescent smoking. PMID:24825218

Gender differences in brain dopaminergic activity have been variably reported in the literature. We performed an evaluation for gender effects on striatal dopamine transporter (DAT) binding in a group of normal subjects. Community-dwelling adults (n = 85, 50F/35M, mean age 62.7 ± 16.2 SD, range 20-85) underwent DAT [(11)C]2-β-carbomethoxy-3β-(4-fluorophenyl) tropane (β-CFT) positron emission tomography (PET) imaging. Gender effects for DAT binding were compared using ANCOVA for two subgroups; young-to-middle aged adults and older adults, using an age threshold of 60 years. There were 54 subjects (24M/30F; mean age 72.9 ± 7.3) 60 years and older and 31 (11M/20F; mean age 45.0 ± 11.4) subjects younger than 60. Age-adjusted striatal DAT gender effects were present in the young-to-middle (F = 10.4, P = 0.003) but not in the elderly age group (F = 0.5, ns). Gender differences in nigrostriatal dopaminergic innervation are present, with higher levels of DAT binding in young-to-middle age women compared to men, but not present in the elderly.

Researchers have hypothesized that men gain greater reward from alcohol than women. However, alcohol-administration studies testing participants drinking alone have offered weak support for this hypothesis. Research suggests that social processes may be implicated in gender differences in drinking patterns. We examined the impact of gender and alcohol on “emotional contagion”—a social mechanism central to bonding and cohesion. Social drinkers (360 male, 360 female) consumed alcohol, placebo, or control beverages in groups of three. Social interactions were video recorded, and both Duchenne and non-Duchenne smiling were continuously coded using the Facial Action Coding System. Results revealed that Duchenne smiling (but not non-Duchenne smiling) contagion correlated with self-reported reward and typical drinking patterns. Importantly, Duchenne smiles were significantly less “infectious” among sober male versus female groups, and alcohol eliminated these gender differences in smiling contagion. Findings identify new directions for research exploring social-reward processes in the etiology of alcohol problems. PMID:26504673

This study examined the attribution of mild cognitive impairment (MCI) etiology assigned by individuals with MCI and their care partners, and the extent to which the dyads agreed on the attribution of MCI etiology. We conducted secondary analyses of cross-sectional data from a cohort of individuals with MCI (n = 60) and their care partners (n = 60). The mean age of the individuals with MCI was 71.0 ± 9.4 years and of care partners 64.2 ± 11.0 years. The primary outcome was attribution assigned to memory deficits on the Illness Perception Questionnaire. We categorized the attribution of MCI etiology as either potentially controllable or uncontrollable factors. We described the distribution of MCI etiology with descriptive and contingency tables. We determined the odds of a patient or care partner choosing one type of MCI etiology over another. Although individuals with MCI and their care partners most frequently attributed MCI to uncontrollable factors (81.7% and 61.0%, respectively), care partners were 28.41 (95% CI, 1.26 to 645.48) times more likely to attribute MCI etiology to potentially controllable factors than individuals with MCI. No significant associations between demographic factors and attribution of MCI etiology were found for the individuals with MCI or the care partners. Findings demonstrated that members of the dyad attributed MCI etiology to different causes. Attributions of MCI etiology should be explored by professionals to clarify misconceptions and potentially improve subsequent voluntary actions intended to assist oneself or others.

Suicide and other suicidal behaviours are markedly (though differently) patterned by gender. The increase in young male suicide rates in many countries has heightened interest in whether suicidal behaviours and ideation (thoughts) are related to masculinity. Relatively little research has explored the relationship between gender role attitudes and orientation and suicidal behaviours and ideation. Most research in this area has been conducted with young people. We investigated whether gender role orientation (masculinity and femininity scores) and gender role attitudes were related to the reporting of serious suicidal thoughts in three generations (early adulthood, and early and late middle age) in a community sample. Subjects (653 men and women aged around 23 years, 754 aged around 43 years, 722 aged around 63 years) completed home interviews with nurses as part of an ongoing longitudinal community-based study of social factors and health. These included measures of suicidal ideation (thoughts), attitudes to traditional gender roles, and a validated measure of gender role orientation (masculinity and femininity scores). The prevalence of serious suicidal thoughts was higher in early adulthood (10% men, 15% women) than in early (4% men, 8% women) and late (6% men, 5% women) middle age. In early adulthood only sex was significantly related to suicidal thoughts, with women at higher risk (adjusted OR 1.74, 95% CI 1.01-3.00). In early middle age masculinity scores were negatively related to suicidal thoughts (adjusted OR for each unit increase in score 0.65: 95% CI 0.46-0.93), and more traditional views on gender roles were positively associated with suicidal thoughts (adjusted OR 1.48: 95% CI 1.07-2.04). In late middle age trends were in the same direction as in early middle age, but were not statistically significant. Femininity scores were unrelated to serious suicidal thoughts at any age. The high rates of suicidal thoughts amongst men and women in early adulthood point to the importance of understanding mental health problems at this age. The results raise a number of questions and suggest that suicide researchers should pay more attention to gender roles and attitudes in older adults.

Multiple standards of aging: gender-specific age stereotypes in different life domains.

Whereas it is often stated that aging might have more negative consequences for the evaluation of women compared to men, evidence for this assumption is mixed. We took a differentiated look at age stereotypes of men and women, assuming that the life domain in which older persons are rated moderates gender differences in age stereotypes. A sample of 298 participants aged 20-92 rated 65 - year-old men and women on evaluative statements in eight different life domains. Furthermore, perceptions of gender- and domain-specific age-related changes were assessed by comparing the older targets to 45 - year-old men and women, respectively. The results speak in favor of the domain specificity of evaluative asymmetries in age stereotypes for men and women, and imply that an understanding of gendered perceptions of aging requires taking into account the complexities of domain-specific views on aging.

[The changing gaps of life expectancy on genders in urban cities of China, from 2005 to 2010].

To analyze the gender difference of life expectancy in urban people of China and to explore both age-specific and cause-specific contributions to the changing differences in life expectancy on genders. Data on life expectancy (male and female) and mortality were obtained from the"Annual Statistics of public health in China". Male-female gender difference was analyzed by decomposition methodologies, including age-specific decomposition and the cause-specific decomposition. Women had lived much longer than men in the Chinese urban citizens, with remarkable gains in life expectancy since 2005. Difference in gender reached a peak in 2007, with the gap of 5.3 years. Differences on mortality between men and women in the 60-79 age groups made the largest contribution (42%-47%) to the gap of 6 years on life expectancy in genders. With the widening of the gaps in gender on life expectancy between 2005 and 2007, faster declining of mortality among groups of women in age 0-1 age and over 75 years old groups made the largest contributions. Between 2007 and 2008, along with the reduction of gaps in gender, all the age groups except the 1-15 and 50-55 year-olds showed negative efforts. In 2009-2010, the widening gaps in gender on life expectancy were caused by the positive effect in the 60-70 age group. Among all the causes of death, cancer (1.638-2.019 years), circulatory diseases (1.271-1.606 years), respiratory diseases (0.551-0.800 years) made the largest contributions to the gender gap. 33%-38% of the gaps in gender were caused by cancer and among all the cancers, among which lung cancer contributed 0.6 years to the overall gap. Contribution of cancers to the gender gap was reducing, but when time went on it was mostly influenced by the narrowing effect caused by liver cancer on the gap in gender. Traffic accidents and suicidal issues were the external causes that influencing the gender gap and contributing 10.60%-15.78% to the overall differentials. Public health efforts in reducing the excess mortalities for cancer, circulatory and respiratory diseases, suicide, among men in particular, will further narrow the gender gap on life expectancy in the urban cities of China.

Although oropharyngeal and laryngeal structures are essential for swallowing, the three-dimensional (3D) anatomy is not well understood, due in part to limitations of available measuring techniques. This study uses 3D images acquired by 320-row area detector computed tomography ('320-ADCT'), to measure the pharynx and larynx and to investigate the effects of age, gender and height. Fifty-four healthy volunteers (30 male, 24 female, 23-77 years) underwent one single-phase volume scan (0.35 s) with 320-ADCT during resting tidal breathing. Six measurements of the pharynx and two of larynx were performed. Bivariate statistical methods were used to analyse the effects of gender, age and height on these measurements. Length and volume were significantly larger for men than for women for every measurement (P < 0.05) and increased with height (P < 0.05). Multiple regression analysis was performed to understand the interactions of gender, height and age. Gender, height and age each had significant effects on certain values. The volume of the larynx and hypopharynx was significantly affected by height and age. The length of pharynx was associated with gender and age. Length of the vocal folds and distance from the valleculae to the vocal folds were significantly affected by gender (P < 0.05). These results suggest that age, gender and height have independent and interacting effects on the morphology of the pharynx and larynx. Three-dimensional imaging and morphometrics using 320-ADCT are powerful tools for efficiently and reliably observing and measuring the pharynx and larynx. © 2015 John Wiley & Sons Ltd.

The purposes of this study were to examine age and gender differences in throwing performance across an underexplored portion of the lifespan: middle adolescents (14-17 years old), young adults (18-25 years old), and adults (35-55 years old). Throwing performance was assessed using the body component levels from Roberton's developmental sequences for force and ball velocity that were recorded by a radar gun. Participants in each age group performed between 5 to 10 forceful overhand throws toward a target approximately 15m to 20m from the thrower. A Wilcoxon-Mann-Whitney Test was used to determine gender differences and a Wilcoxon-Signed Ranks Test was used to determine age-group differences for each component. Gender and age-group differences in ball speed were determined by a 3 (age group) x 2 (gender) factorial analysis of variance with follow-up post-hoc tests. Young-adult men had higher body component levels and ball speed compared with the adolescent boys and adult men. Female age-group differences existed only for humerus action between young-adult and adult groups and for ball speed between young-adult and adolescent groups. Gender differences (p < .01) existed in component levels for the adolescent and young-adult groups, but not the adult groups. Gender differences in ball speed (p < .001) existed within each age group. Although these data were cross-sectional, the regressive developmental changes observed and the narrowing gender gap may eventually provide insight related to the relationships among motor skill competence, physical fitness, and physical activity across the lifespan.

Most research to date on implicit gender stereotyping has been conducted with one age group – young adults. The mechanisms that underlie the on-line processing of stereotypical information in other age groups have received very little attention. This is the first study to investigate real time processing of gender stereotypes at different age levels. We investigated the activation of gender stereotypes in Italian in four groups of participants: third- and fifth-graders, young and older adults. Participants heard a noun that was stereotypically associated with masculine (preside “headmaster”) or feminine roles (badante “social care worker”), followed by a male (padre “father”) or female kinship term (madre “mother”). The task was to decide if the two words – the role noun and the kinship term – could describe the same person. Across all age groups, participants were significantly faster to respond, and significantly more likely to press ‘yes,’ when the gender of the target was congruent with the stereotypical gender use of the preceding prime. These findings suggest that information about the stereotypical gender associated with a role noun is incorporated into the mental representation of this word and is activated as soon as the word is heard. In addition, our results show differences between male and female participants of the various age groups, and between male- and female-oriented stereotypes, pointing to important gender asymmetries.

In contrast to the extensive knowledge on the association between women's empowerment and the nutritional status of children under the age of five, relatively little is known about the influence of women's empowerment on adolescents' nutritional status. This study aimed to assess the association between women's empowerment and gender inequalities in adolescent nutritional status. Data were from the Indonesian Family Life Survey (IFLS) covering the period 1997 to 2015, and consisted of 16,683 observations from 13,396 adolescents between the ages of 10 and 19 years born in 6781 families. Three indicators of women's empowerment were used: mother's education, mother's bargaining power and mother's working status. Multivariate linear regression with robust standard errors was used to examine whether and how these indicators of women's empowerment influenced adolescent nutritional status. Interaction terms were added to analyse how the association between women's empowerment and adolescent nutritional status differed by gender. The results showed that mother's education and mother's working status were significantly associated with adolescent nutritional status, particularly with height-for-age. Adolescents of well-educated mothers had a higher height-for-age while those who were raised by mothers with a blue-collar job had a lower height-for-age. Although no gender differences were found for height-for-age, gender differences for BMI-for-age were obvious, with boys having a lower BMI-for-age than girls. Interactions between indicators of mother's empowerment and gender showed that the gender gap in BMI-for-age was smaller for adolescents of more educated mothers. However, further analyses of food consumption patterns showed that boys whose mothers were more educated consumed more fast food and had higher instant noodle consumption than girls, thus suggesting gender bias in new disguise.

The purpose of this study was to investigate the influences of gender and age on defibrillator lead failure and patient mortality. The specific influences of gender and age on defibrillator lead failure have not previously been investigated. This study analyzed the differences in gender and age in relation to defibrillator lead failure and mortality of patients in the Pacemaker and Implantable Defibrillator Leads Survival Study ("PAIDLESS"). PAIDLESS includes all patients at Winthrop University Hospital who underwent defibrillator lead implantation between February 1, 1996 and December 31, 2011. Male and female patients were compared within each age decile, beginning at 15 years old, to analyze lead failure and patient mortality. Statistical analyses were performed using Wilcoxon rank-sum test, Fisher's exact test, Kaplan-Meier analysis, and multivariable Cox regression models. P<.05 was considered statistically significant. No correction for multiple comparisons was performed for the subgroup analyses. A total of 3802 patients (2812 men and 990 women) were included in the analysis. The mean age was 70 ± 13 years (range, 15-94 years). Kaplan-Meier analysis found that between 45 and 54 years of age, leads implanted in women failed significantly faster than in men (P=.03). Multivariable Cox regression models were built to validate this finding, and they confirmed that male gender was an independent protective factor of lead failure in the 45 to 54 years group (for male gender: HR, 0.37; 95% confidence interval, 0.14-0.96; P=.04). Lead survival time for women in this age group was 13.4 years (standard error, 0.6), while leads implanted in men of this age group survived 14.7 years (standard error, 0.3). Although there were significant differences in lead failure, no differences in mortality between the genders were found for any ages or within each decile. This study is the first to compare defibrillator lead failure and patient mortality in relation to gender and age deciles at a single large implanting center. Within the 45 to 54 years group, leads implanted in women failed faster than in men. Male gender was found to be an independent protective factor in lead survival. This study emphasizes the complex interplay between gender and age with respect to implantable defibrillator lead failure and mortality.

A non-invasive bioimpedance spectroscopy (BIS) and Cole-Cole impedance model parameters (R0, R∞, τ and α) were used to analyze electrical properties of intact and stripped human skin for both gender subjects divided into younger and older age groups. R0, R∞ and τ significantly increased while α significantly decreased with age in stripped skin for both genders (p<0.031). Using pooled data with respect to age, gender and skin stripping, R0, R∞ and τ values were shown to increase with age (p<0.0034), R0, τ and α were different between genders (p<0.024) and R0, R∞ and τ decreased with skin stripping (p<0.000008). All of four Cole-Cole parameters were age dependent with specific differences observed for genders and intact and stripped skin layers. Therefore, Cole-Cole parameters, obtained by non-invasive BIS measurements, are a new type of age dependent biomarkers. Copyright © 2014 Elsevier Inc. All rights reserved.

As the workforce ages, occupational injuries from falls on the same level will increase. Some industries may be more affected than others. We conducted a cross-sectional study using data from the Bureau of Labor Statistics to estimate same-level fall injury incidence rates by age group, gender, and industry for four sectors: 1) healthcare and social assistance; 2) manufacturing; 3) retail; and 4) transportation and warehousing. We calculated rate ratios and rate differences by age group and gender. Same-level fall injury incidence rates increase with age in all four sectors. However, patterns of rate ratios and rate differences vary by age group, gender, and industry. Younger workers, men, and manufacturing workers generally have lower rates. Variation in incidence rates suggests there are unrealized opportunities to prevent same-level fall injuries. Interventions should be evaluated for their effectiveness at reducing injuries, avoiding gender- or age-discrimination and improving work ability. © 2017 Wiley Periodicals, Inc.

Despite some evidence of greater age-related deterioration of the brain in males than in females, gender differences in rates of cognitive aging have proved inconsistent. The present study employed web-based methodology to collect data from people aged 20-65 years (109,612 men; 88,509 women). As expected, men outperformed women on tests of mental rotation and line angle judgment, whereas women outperformed men on tests of category fluency and object location memory. Performance on all tests declined with age but significantly more so for men than for women. Heterosexuals of each gender generally outperformed bisexuals and homosexuals on tests where that gender was superior; however, there were no clear interactions between age and sexual orientation for either gender. At least for these particular tests from young adulthood to retirement, age is kinder to women than to men, but treats heterosexuals, bisexuals, and homosexuals just the same.

Background: Since developmental psychologists are interested in explaining age and gender differences in depression across adolescence, it is important to investigate to what extent these observed differences can be attributed to measurement bias. Measurement bias may arise when the phenomenology of depression varies with age or gender, i.e., when…

Although the lipophilic yeasts of the genus Malassezia are part of the cutaneous microbiota in healthy individuals, they are also associated with several skin diseases, such as seborrheic dermatitis. However, the effects of age and gender on the Malassezia microbiota have not been completely elucidated. We analyzed the cutaneous Malassezia microbiota of 770 healthy Japanese using the highly accurate real-time PCR with a TaqMan probe to investigate the effects of age and gender on the Malassezia population. The numbers of Malassezia cells increased in males up to 16-18 years of age and in females to 10-12 years old, and subsequently decreased gradually in both genders until senescence. Malassezia restricta overwhelmingly predominated at ages over 16-18 years in males and 23-29 years in females. M. globosa and M. restricta together accounted for more than 70% of Malassezia spp. recovered regardless of gender. The total colonization of Malassezia and the ratio of the two major species change with age and gender in humans.

The purpose of this study was to identify and compare the results of the findings from speech-language pathology evaluations for orofacial function including tongue and lip rest postures, tonus, articulation and speech, voice and language, chewing, and deglutition in children who had a history of mouth breathing. The diagnoses for mouth breathing included: allergic rhinitis, adenoidal hypertrophy, allergic rhinitis with adenoidal hypertrophy; and/or functional mouth breathing. This study was conducted with on 414 subjects of both genders, from 2 to 16-years old. A team consisting of 3 speech-language pathologists, 1 pediatrician, 1 allergist, and 1 otolaryngologist, evaluated the patients. Multidisciplinary clinical examinations were carried out (complete blood counting, X-rays, nasofibroscopy, audiometry). The two most commonly found etiologies were allergic rhinitis, followed by functional mouth breathing. Of the 414 patients in the study, 346 received a speech-language pathology evaluation. The most prevalent finding in this group of 346 subjects was the presence of orofacial myofunctional disorders. The most frequently orofacial myofunctional disorder identified in these subjects who also presented mouth breathing included: habitual open lips rest posture, low and forward tongue rest posture and lack of adequate muscle tone. There were also no statistically significant relationships identified between etiology and speech-language diagnosis. Therefore, the specific type of etiology of mouth breathing does not appear to contribute to the presence, type, or number of speech-language findings which may result from mouth breathing behavior.

To evaluate whether ovulatory dysfunction due to polycystic ovary syndrome (PCOS) is a common underlying etiology of abnormal uterine bleeding (AUB) in adolescents who require hospitalization and to explore etiology, treatment, and complications of AUB with severe anemia in adolescents. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: We identified female patients aged 8-20 years admitted to a children's hospital for treatment of AUB from January 2000 to December 2014. Our hospital protocol advises hormonal testing for PCOS and other disorders before treatment for AUB. We reviewed medical records and recorded laboratory evaluations, treatments, and final underlying diagnoses as well as recurrences of AUB and readmissions in the subsequent year. Of the 125 subjects, the mean age was 16.5 ± 2.9 years; mean hemoglobin level was 7.0 ± 1.8 g/dL; 54% were overweight/obese; and 41% sexually active. PCOS accounted for 33% of admissions; hypothalamic pituitary ovarian axis immaturity 31%; endometritis 13%; bleeding disorders 10%. Girls with PCOS were more likely to be overweight/obese (74% vs 46%; P < .01) and girls with hypothalamic pituitary ovarian axis immaturity had lower hemoglobin levels (6.4 g/dL vs 7.4 g/dL; P < .05), than girls with all other etiologies of AUB. Treating physicians failed to diagnose endometritis as the etiology for AUB in 4 of 8 girls with positive tests for sexually transmitted infection and no other etiology. PCOS was the most common underlying etiology in adolescents hospitalized with AUB. Screening for hyperandrogenemia is important for early diagnosis of PCOS to allow ongoing management and prevention of comorbidities. Endometritis was frequently underestimated as an etiology for AUB. Copyright © 2016 North American Society for Pediatric and Adolescent Gynecology. Published by Elsevier Inc. All rights reserved.

Background Dietary habits are major contributors to coronary heart disease, stroke, and diabetes. However, comprehensive evaluation of etiologic effects of dietary factors on cardiometabolic outcomes, their quantitative effects, and corresponding optimal intakes are not well-established. Objective To systematically review the evidence for effects of dietary factors on cardiometabolic diseases, including comprehensively assess evidence for causality; estimate magnitudes of etiologic effects; evaluate heterogeneity and potential for bias in these etiologic effects; and determine optimal population intake levels. Methods We utilized Bradford-Hill criteria to assess probable or convincing evidence for causal effects of multiple diet-cardiometabolic disease relationships. Etiologic effects were quantified from published or de novo meta-analyses of prospective studies or randomized clinical trials, incorporating standardized units, dose-response estimates, and heterogeneity by age and other characteristics. Potential for bias was assessed in validity analyses. Optimal intakes were determined by levels associated with lowest disease risk. Results We identified 10 foods and 7 nutrients with evidence for causal cardiometabolic effects, including protective effects of fruits, vegetables, beans/legumes, nuts/seeds, whole grains, fish, yogurt, fiber, seafood omega-3s, polyunsaturated fats, and potassium; and harms of unprocessed red meats, processed meats, sugar-sweetened beverages, glycemic load, trans-fats, and sodium. Proportional etiologic effects declined with age, but did not generally vary by sex. Established optimal population intakes were generally consistent with observed national intakes and major dietary guidelines. In validity analyses, the identified effects of individual dietary components were similar to quantified effects of dietary patterns on cardiovascular risk factors and hard endpoints. Conclusions These novel findings provide a comprehensive summary of causal evidence, quantitative etiologic effects, heterogeneity, and optimal intakes of major dietary factors for cardiometabolic diseases, informing disease impact estimation and policy planning and priorities.

Pericardial effusion can occur as a result of primary pericardial disease or secondary to systemic disease. Analysis of the features of pericardial effusion in correlation with clinical and demographic findings can help clinicians to determine the correct diagnosis and to choose the appropriate treatment and reduce patient mortality and morbidity. Retrospective analysis of the characteristics of pericardial effusion and the prevalence of the different etiologies and their correlation with demographics, clinical characteristics and medical history in 86 patients admitted to Galilee Medical Center from 2001 to 2010 who underwent pericardiocentesis or pericardial window. The most common etiology was idiopathic - 36% of cases, followed by cancer - 31.4%, coronary artery disease - 16.3%, renal failure - 4.6%, trauma - 4.6%, autoimmune disease - 4.6%, cirrhosis of liver - 1.2% of cases and hypothyroidism with 1.2% of cases. Laboratory tests rarely contributed to the diagnostic process; the most common symptom was dyspnea (76.6%). Most of the effusions were exudates (70.9%), and use of anti-coagulants increased the tendency to develop a bloody effusion (p=0.031). Idiopathic etiology, coronary heart disease or renal failure were more frequent in Arabs (58%, 57% and 75%, respectively) than in Jews (42%, 43% and 25%, respectively). In contrast, Jews had more malignant effusion (67% Jews and 33% Arabs). The average age of patients of all etiologies, except for trauma, was > 60 years (only 7% of patients were under the age of 17 years); the idiopathic etiology was mainly exudative (50%), compared with a transudative effusion in which coronary heart disease was most common (46%). The spectrum of etiologies of large symptomatic pericardial effusion in a community hospital in the Western Galilee region in the contemporary era is continuously evolving. Currently, the most frequent etiology is idiopathic, followed by malignancy. Routine laboratory testing rarely affects the pre-pericardiocentesis diagnosis.

Background Acute encephalitis is an important and severe disease in children in Vietnam. However, little is known about the etiology while such knowledge is essential for optimal prevention and treatment. To identify viral causes of encephalitis, in 2004 we conducted a one-year descriptive study at Children's Hospital Number One, a referral hospital for children in southern Vietnam including Ho Chi Minh City. Methodology/Principal Findings Children less than 16 years of age presenting with acute encephalitis of presumed viral etiology were enrolled. Diagnostic efforts included viral culture, serology and real time (RT)-PCRs. A confirmed or probable viral causative agent was established in 41% of 194 enrolled patients. The most commonly diagnosed causative agent was Japanese encephalitis virus (n = 50, 26%), followed by enteroviruses (n = 18, 9.3%), dengue virus (n = 9, 4.6%), herpes simplex virus (n = 1), cytomegalovirus (n = 1) and influenza A virus (n = 1). Fifty-seven (29%) children died acutely. Fatal outcome was independently associated with patient age and Glasgow Coma Scale (GCS) on admission. Conclusions/Significance Acute encephalitis in children in southern Vietnam is associated with high mortality. Although the etiology remains unknown in a majority of the patients, the result from the present study may be useful for future design of treatment and prevention strategies of the disease. The recognition of GCS and age as predictive factors may be helpful for clinicians in managing the patient. PMID:21049060

A case-control study aiming to evaluate the relationship between Bsm I and Apa I restriction fragment gene polymorphisms and colorectal cancer (CRC) was carried out in Kashmir, including a total of 368 subjects (180 cases and 188 controls). DNA samples extracted from the blood of the subjects were analyzed for 3' untranslated region (3' UTR) Apa I and Bsm I polymorphisms using restriction fragment length polymorphism-polymerase chain reaction (RFLP-PCR). A statistically significant 2.7-fold increased risk was observed in individuals found homozygous for the presence of the 'b' allele, in comparison to subjects homozygous for the 'B' allele (odds ratio (OR) 2.7, 95% confidence interval (CI) 1.49-4.86 (Bsm I)), and a statistically insignificant 2-fold increased risk was found among individuals with the 'aa' genotype, as compared to subjects with the 'AA' genotype (OR 2.017, 95% CI 0.86-4.7). Our study also yielded statistically significant results when the Apa I polymorphism was stratified by age (≤ 50 years) and dwelling area (rural area), and the Bsm I polymorphism by gender (male gender), suggesting a possible role of Apa I and Bsm I polymorphisms in the etiology of CRC in Kashmir. We conclude that Apa I and Bsm I single-nucleotide polymorphisms (SNPs) in the vitamin D receptor gene (VDR) might be associated with susceptibility to CRC among Kashmiris. © 2014 S.

Motives for gambling have been shown to be associated with gambling involvement, and hence important in the understanding of the etiology of problem gambling. The aim of this study was to describe differences in gambling motives in different subgroups of lifetime risk gamblers, categorized by: age, gender, alcohol- and drug habits and type of game preferred, when considering the level of risk gambling. A random Swedish sample (n = 19,530) was screened for risk gambling, using the Lie/Bet questionnaire. The study sample (n = 257) consisted of the respondents screening positive on Lie/Bet and completing a postal questionnaire about gambling and motives for gambling (measured with the NODS-PERC and the RGQ respectively). When considering the level of risk gambling, motives for gambling were not associated with gender, whereas younger persons gambled for the challenge more often than did older participants. Card/Casino and Sport gamblers played to a greater extent for social and challenge reasons then did Lotto/Bingo-gamblers. EGM-gamblers played more for coping reasons than did Lotto/Bingo gamblers. However, this association turned non-significant when considering the level of risk gambling. Moderate risk gamblers played for the challenge and coping reasons to a greater extent than low risk gamblers motives for gambling differ across subgroups of preferred game and between gamblers with low and moderate risk. The level of risk gambling is intertwined with motives for gambling and should be considered when examining gambling reasons.

To determine racial and gender differences in long-term survival following ischemic stroke in a well-defined cohort of patients. We analyzed the prospectively collected data from a randomized, placebo-controlled trial in patients with ischemic stroke presenting within 3 hours of symptom onset. We determined the effect of race and gender on 1-year survival ascertained by serial follow-ups using Kaplan-Meier analysis. Multivariate analysis was performed adjusting for age, initial NIH Stroke Scale (NIHSS) score, use of thrombolysis, time to randomization, stroke etiology, and other cardiovascular risk factors. Of the 547 patients with ischemic stroke, the 1-year survival (percentage +/- SE) for African American women (63 +/- 6%) was lower than white women (73 +/- 4%), African American men (79 +/- 4%), and white men (75 +/- 3%). Among the 209 patients younger than 65 years, the 1-year survival was prominently lower for African American women (66 +/- 8%) vs white women (87 +/- 5%), African American men (83 +/- 5%), and white men (89 +/- 3%). In the Cox proportional hazard analysis, African American women had a significantly higher rate of 1-year mortality (relative risk 2.1, 95% CI 1.2 to 3.5) after adjusting for all potential confounders except diabetes mellitus. After adjustment for diabetes mellitus, the difference became insignificant, although a 70% greater risk of 1-year mortality was still observed. Compared with whites and men, African American women have a lower 1-year survival following ischemic stroke.

To report the etiology of liver cirrhosis cases diagnosed at the University Hospital in Vitoria, Espirito Santo, Brazil. The medical charts of patients with liver cirrhosis who presented to the University Hospital in Vitoria were reviewed. Chronic alcoholism and the presence of hepatitis B or C infections (HBV and HCV, respectively) were pursued in all cases. The sample consisted of 1,516 cases (male:female ratio 3.5:1, aged 53.2 ± 12.6 years). The following main etiological factors were observed: chronic alcoholism alone (39.7%), chronic alcoholism in association with HBV or HCV (16.1 %), HCV alone (14.5%) and in association with alcoholism (8.6%) (total, 23.1 %), and HBV alone (13.1%) and in association with alcoholism (7.5%, total 20.6%). The remaining etiologies included cryptogenic cases (9.8%) and other causes (6.0%). The mean patient age was lower and the male-to-female ratio was higher in the cirrhosis cases that were associated with alcoholism or HBV compared with other causes. Intravenous drug abuse and a history of surgery or blood transfusion were significantly associated with HCV infection. Hepatocellular carcinoma was present at the time of diagnosis in 15.4% of cases. Chronic alcoholism associated with HCV infection was significantly associated (p<0.001) with reduced age (at the time of cirrhosis diagnosis) and increased prevalence of hepatocellular carcinoma (p = 0.052). Alcoholism, HCV and HBV are the main factors associated with liver cirrhosis in the state of Espirito Santo. Chronic alcoholism associated with HCV infection reduced the age of patients at the time of liver cirrhosis diagnosis.

Environmental risk factors for chronic lymphocytic leukemia (CLL) have not been consistently identified. An etiologic role for ionizing radiation in CLL is controversial. Because most of the ionizing radiation to which individuals are exposed comes from radon at home, we examined CLL incidence rates in relation to residential radon levels. We used population-based rates for CLL for US states from 2007 to 2011 and measurements of residential radon made by the US Environmental Protection Agency. Incidence rates for CLL were significantly correlated with residential radon levels among whites (both genders together and each gender separately; p < 0.005) and among blacks (p < 0.05). We speculate that radon increases CLL risk and that the mechanisms may be similar to those by which radon causes lung cancer.

Although gender differences in mental rotation in younger adults are prominent in paper-pencil tests as well as in chronometric tests with polygons as stimuli, less is known about this topic in the older age ranges. Therefore, performance was assessed with the Mental Rotation Test (MRT) paper-pencil test as well as with a computer-based two-stimulus same-different task with polygons in a sample of 150 adults divided into three age groups, 20-30, 40-50, and 60-70 years. Performance decreased with age, and men outperformed women in all age groups. The gender effect decreased with age in the MRT, possibly due to a floor effect. Gender differences remained constant across age, however, in the error rates of the computer-based task.

2013-11-01

In order to compare multidimensional fatigue research findings across age and gender subpopulations, it is important to demonstrate measurement invariance, that is, that the items from an instrument have equivalent meaning across the groups studied. This study examined the factorial invariance of the 18-item PedsQL™ Multidimensional Fatigue Scale items across age and gender and tested a bifactor model. Multigroup confirmatory factor analysis (MG-CFA) was performed specifying a three-factor model across three age groups (5-7, 8-12, and 13-18 years) and gender. MG-CFA models were proposed in order to compare the factor structure, metric, scalar, and error variance across age groups and gender. The analyses were based on 837 children and adolescents recruited from general pediatric clinics, subspecialty clinics, and hospitals in which children were being seen for well-child checks, mild acute illness, or chronic illness care. A bifactor model of the items with one general factor influencing all the items and three domain-specific factors representing the General, Sleep/Rest, and Cognitive Fatigue domains fit the data better than oblique factor models. Based on the multiple measures of model fit, configural, metric, and scalar invariance were found for almost all items across the age and gender groups, as was invariance in the factor covariances. The PedsQL™ Multidimensional Fatigue Scale demonstrated strict factorial invariance for child and adolescent self-report across gender and strong factorial invariance across age subpopulations. The findings support an equivalent three-factor structure across the age and gender groups studied. Based on these data, it can be concluded that pediatric patients across the groups interpreted the items in a similar manner regardless of their age or gender, supporting the multidimensional factor structure interpretation of the PedsQL™ Multidimensional Fatigue Scale.

Individuals with chronic whiplash associated disorders (WAD) present persistent pain in the absence of structural pathology. In these people, altered central pain processing and central sensitization are observed. The role of personal factors, such as gender and age, on pain processing mechanisms in chronic WAD, however, is still unclear. This study investigated possible gender- and age-related differences in self-reported and experimental pain measurements in people with chronic WAD. Besides the exercise-induced response on pain measurements between gender and age subgroups was recorded. Case-control study. University Hospital, Brussels. Self-reported pain and experimental pain measurements (pressure pain thresholds [PPT], occlusion cuff pressure, temporal summation, and conditioned pain modulation) were performed in 52 individuals (26 chronic WAD patients and 26 healthy controls), before and after a submaximal cycle exercise. Lower PPTs and occlusion cuff pressures were shown in chronic WAD in comparison with healthy controls. No gender and age differences regarding PPTs, occlusion cuff pressures and conditioned pain modulation were found in chronic WAD. Within the chronic WAD group, men showed higher self-reported pain compared to women and younger adults showed enhanced generalized pain facilitation compared to older adults. In addition, chronic WAD patients are able to inhibit exercise-induced hyperalgesia, but no gender and age differences in pain response following exercise were found. This study was sufficiently powered to detect differences between the chronic WAD and control group. However, a sufficient power was not reached when patients were divided in age and gender groups. Furthermore, only mechanical stimuli were included in the experimental pain measurements. Besides, psychosocial factors were not taken into account. Some alterations of altered pain processing are present in chronic WAD patients, however not in response to exercise. No gender and age differences in pain measurements were observed in people with chronic WAD.Key words: Neck pain, whiplash associated disorders, chronic pain, personal factors, age, gender, central sensitization, exercise induced hyperalgesia, pressure pain thresholds, self reported pain.

Acute encephalitis is a severe neurologic syndrome. Determining etiology from among ≈100 possible agents is difficult. To identify infectious etiologies of encephalitis in Thailand, we conducted surveillance in 7 hospitals during July 2003–August 2005 and selected patients with acute onset of brain dysfunction with fever or hypothermia and with abnormalities seen on neuroimages or electroencephalograms or with cerebrospinal fluid pleocytosis. Blood and cerebrospinal fluid were tested for >30 pathogens. Among 149 case-patients, median age was 12 (range 0–83) years, 84 (56%) were male, and 15 (10%) died. Etiology was confirmed or probable for 54 (36%) and possible or unknown for 95 (64%). Among confirmed or probable etiologies, the leading pathogens were Japanese encephalitis virus, enteroviruses, and Orientia tsutsugamushi. No samples were positive for chikungunya, Nipah, or West Nile viruses; Bartonella henselae; or malaria parasites. Although a broad range of infectious agents was identified, the etiology of most cases remains unknown. PMID:25627940

Apallic syndrome may be defined as the complete lack of cortical function - paragnosia and parapraxia. Vegetative functions and other sub cortical functions are maintained (sleep rhythm, suckling and swallowing reflex). The aim of the study was to investigate the recovery of children with Apallic syndrome depending on the etiology and differences among various modalities like self-care, motor control and speech during rehabilitation. The study was conducted among eight children (mean age 9.4) (SD-2.6). Four had a post-traumatic and four Apallic syndrome of ischemic etiology. Friedman and Kruskal-Wallis tests were used for statistical analysis. There was no evident difference in recovery among children with Apallic syndrome of different etiology. In regard to self-care, motor control and speech, all children showed the same level of improvement during rehabilitation therapy. These results correspond with similar research findings. Rehabilitation is essential to aid recovery and it does not depend on the etiology. Recovery success is the same regardless of the chosen modality.

In developed countries, systolic blood pressure is known to increase with age. Metabolic risks may generally worse with increasing age. But this trend may be modified by environmental factors which are different between gender and generation. The aim of this study was to examine the relationship between age and gender-related difference in cardio-metabolic risks and life style factors in the Japanese general population. We studied 3628 inhabitants of Watari (mean age 63.9 yrs, 42.5% men), Miyagi prefecture, who participated in a health check-up in 2009. Anthropometry, sitting blood pressures, fasting blood samples were examined. Unhealthy dietary behaviors (night meal, late dinner, fast eating, skipping breakfast, smoking, heavy drinking, lack of regular exercise) were evaluated by standard questionnaire. Presence or absence of each behavior was scored 0 or 1 and total score was calculated as healthy life style score (range 0 to 7, higher the better). Gender difference in age-related changes in blood pressures, BMI, lipid and glucose metabolism were examined by two way ANOVA. Systolic blood pressure was continuously increased from age 30 s to 70 s in both genders. Systolic blood pressure was significantly higher in men than in women in age 30 s (122.0 ± 13.9 vs. 113.3 ± 12.8 mmHg, p < 0.001) but the difference decreased with an increase in age. Similar gender interaction was observed for diastolic blood pressure, BMI, triglyceride and high density lipoprotein (all p < 0.001) but was not for HbA1c. The healthy life style score was lowest in men age 30 s (5.1 ± 1.5) and it increased with an increase in age. Women demonstrated significantly higher healthy life style score than men in all generations. The gender difference in the score was largest in age 30 s and decreased with an increase in age. Cardio-metabolic risks are worse in men than in women in young generation but this gender difference diminishes with age. The gender difference in the young may be largely attributable to life style factors. Glucose metabolism may be less affected by life style than blood pressure or lipid.

In 2 meta-analyses on gender differences in depression in nationally representative samples, we advance previous work by including studies of depression diagnoses and symptoms to (a) estimate the magnitude of the gender difference in depression across a wide array of nations and ages; (b) use a developmental perspective to elucidate patterns of gender differences across the life span; and (c) incorporate additional theory-driven moderators (e.g., gender equity). For major depression diagnoses and depression symptoms, respectively, we meta-analyzed data from 65 and 95 articles and their corresponding national data sets, representing data from 1,716,195 and 1,922,064 people in over 90 different nations. Overall, odds ratio (OR) = 1.95, 95% confidence interval (CI) [1.88, 2.03], and d = 0.27 [0.26, 0.29]. Age was the strongest predictor of effect size. The gender difference for diagnoses emerged earlier than previously thought, with OR = 2.37 at age 12. For both meta-analyses, the gender difference peaked in adolescence (OR = 3.02 for ages 13-15, and d = 0.47 for age 16) but then declined and remained stable in adulthood. Cross-national analyses indicated that larger gender differences were found in nations with greater gender equity, for major depression, but not depression symptoms. The gender difference in depression represents a health disparity, especially in adolescence, yet the magnitude of the difference indicates that depression in men should not be overlooked.

The aim of this study was to measure the mandibular cortical index (MCI), mental index (MI), panoramic mandibular index (PMI) and cortical bone thickness in the zone of the gonial angle (GT) in panoramic radiographies from a large sample of males and females and to determine how they relate to patients' age, gender and dental status. 910 panoramic radiographs were obtained and grouped into age, dental status and gender. The MCI, MI, PMI and GT were analysed. Remarkable differences were observed for MCI and GT regarding gender, age groups and dental status on both sides (p < 0.05). While age and dental status had an effect on the MI and PMI in females, dental status had an effect on the MI and PMI in males (p < 0.05). Also, gender had an effect on the MI and PMI (p < 0.05). The effects of age and tooth loss are different in females and males. In females, the harmful effects of tooth loss and age are more prominent according to the PMI and MI measurements. The effects of age and tooth loss in the GT and MCI measurements are similar, and these indices can be accepted as more reliable in studies including both genders.

While cystic fibrosis (CF) is the most common cause of bronchiectasis in childhood, non-CF bronchiectasis is associated with a wide variety of disorders. The objective of this study was to determine the relative prevalence and specific etiologies on non-CF bronchiectasis in childhood. EMBASE, Medline, OVID Cochrane Reviews, Directory of Open Access Journals, Open Science Directory, EPSCO information services, and OAlster were searched electronically and the bibliographies of selected studies were searched manually. The search was conducted independently by 2 authors. (1) any clinical trial, observational study or cross-sectional case series of 10 or more patients with a description of the conditions associated with bronchiectasis; (2) subjects aged 21 years or younger; (3) cystic fibrosis was excluded and; (4) the diagnosis was confirmed by computed tomography of the chest. Patient number, age range, inclusion criteria, diagnostic criteria, patient source, and categorical and specific etiology. From 491 studies identified, 12 studies encompassing 989 children with non-CF bronchiectasis were selected. Sixty-three percent of the subjects had an underlying disorder. Infectious (17%), primary immunodeficiency (16%), aspiration (10%), ciliary dyskinesia (9%), congenital malformation (3%), and secondary immunodeficiency (3%) were the most common disease categories; 999 etiologies were identified. Severe pneumonia of bacterial or viral etiology and B cell defects were the most common disorders identified. The majority of children with non-CF bronchiectasis have an underlying disorder. A focused history and laboratory investigated is recommended.

Prolonged conflict in South Sudan exacerbated gender disparities and inequities. This study assessed differences in attitudes towards gender inequitable norms and practices by sex, age and education to inform programming. Applying community-based participatory research methodology, 680 adult respondents, selected by quota sampling, were interviewed in seven South Sudanese communities from 2009 to 2011. The verbally administered survey assessed attitudes using the Gender Equitable Men scale. Data were stratified by sex, age and education. Of 680 respondents, 352 were female, 326 were male and two did not report their sex. The majority of respondents agreed with gender inequitable household roles, but the majority disagreed with gender inequitable practices (i.e., early marriage, forced marriage and inequitable education of girls). Respondents who reported no education were more likely than those who reported any education to agree with gender inequitable practices (all p < 0.03) except for forced marriage (p = 0.07), and few significant differences were observed when these responses were stratified by sex and by age. The study reveals agreement with gender inequitable norms in the household but an overall disagreement with gender inequitable practices in sampled communities. The findings support that education of both women and men may promote gender equitable norms and practices.

Do gender differences in audio-visual benefit and visual influence in audio-visual speech perception emerge with age?

PubMed Central

Alm, Magnus; Behne, Dawn

2015-01-01

Gender and age have been found to affect adults’ audio-visual (AV) speech perception. However, research on adult aging focuses on adults over 60 years, who have an increasing likelihood for cognitive and sensory decline, which may confound positive effects of age-related AV-experience and its interaction with gender. Observed age and gender differences in AV speech perception may also depend on measurement sensitivity and AV task difficulty. Consequently both AV benefit and visual influence were used to measure visual contribution for gender-balanced groups of young (20–30 years) and middle-aged adults (50–60 years) with task difficulty varied using AV syllables from different talkers in alternative auditory backgrounds. Females had better speech-reading performance than males. Whereas no gender differences in AV benefit or visual influence were observed for young adults, visually influenced responses were significantly greater for middle-aged females than middle-aged males. That speech-reading performance did not influence AV benefit may be explained by visual speech extraction and AV integration constituting independent abilities. Contrastingly, the gender difference in visually influenced responses in middle adulthood may reflect an experience-related shift in females’ general AV perceptual strategy. Although young females’ speech-reading proficiency may not readily contribute to greater visual influence, between young and middle-adulthood recurrent confirmation of the contribution of visual cues induced by speech-reading proficiency may gradually shift females AV perceptual strategy toward more visually dominated responses.

This study integrates healthy ageing and health psychology theories to explore the mechanisms underlying the relationship between health control expectancies and age-attitudes on the process of ageing well. Specifically, the aim of this study is to investigate the relationship between age-stereotypes and health locus of control. A population-based survey of 739 adults aged 20-97 years (mean = 57.3 years, SD = 13.66; 42% female) explored attitudes towards ageing and health attitudes. A path-analytical approach was used to investigate moderating effects of age and gender. Higher age-stereotype endorsement was associated with higher chance (β = 2.91, p < .001) and powerful other (β = 1.07, p = .012) health expectancies, after controlling for age, gender, education and self-rated health. Significant age and gender interactions were found to influence the relationship between age-stereotypes and internal health locus of control. Our findings suggest that the relationship between age-stereotypes and health locus of control dimensions must be considered within the context of age and gender. The findings point to the importance of targeting health promotion and interventions through addressing negative age-attitudes.

Introduction Falls are the leading cause of injury in almost all age-strata in the U.S. However, fall-related injuries (FI) and their circumstances are under-studied at the population level, particularly among young and middle-aged adults. This study examined the circumstances of FI among community-dwelling U.S. adults, by age and gender. Methods Narrative texts of FI from the National Health Interview Survey (1997–2010) were coded using a customized taxonomy to assess place, activity, initiating event, hazards, contributing factors, fall height, and work-relatedness of FI. Weighted proportions and incidence rates of FI were calculated across six age-gender groups (18–44, 45–64, 65+ years; women, men). Results The proportion of FI occurring indoors increased with age in both genders (22%, 30%, and 48% among men, and 40%, 49% and 62% among women for 18–44, 45–64, 65+ age-groups, respectively). In each age group the proportion of indoor FI was higher among women as compared to men. Among women, using the stairs was the second leading activity (after walking) at the time of FI (19%, 14% and 10% for women in 18–44, 45–64, 65+ age groups, respectively). FI associated with tripping increased with age among both genders, and women were more likely to trip than men in every age group. Of all age-gender groups, the rate of FI while using ladders was the highest among middle-aged men (3.3 per 1000 person-year, 95% CI 2.0, 4.5). Large objects, stairs and steps, and surface contamination were the three most common hazards noted for 15%, 14% and 13% of fall-related injuries, respectively. Conclusions The rate and the circumstances of FI differ by age and gender. Understanding these differences and obtaining information about circumstances could be vital for developing effective interventions to prevent falls and FI. PMID:28472065

Background: Gender differences exist in psychiatric disorders; however gender has not been well studied in psychotic depression. This analysis of the largest clinical trial in psychotic depression examined the effects of age and gender on clinical characteristics and predictors of treatment outcome and treatment-associated changes in body mass index (BMI) and metabolic measures. Methods: Analyses were performed on data from 259 subjects aged 18-93 in the double-blind randomized controlled trial of olanzapine plus sertraline (OLZ/SERT) vs. olanzapine plus placebo (OLZ/PBO) for psychotic depression (STOP-PD). Sociodemographic factors, clinical characteristics, treatment outcome and treatment-associated changes in BMI and metabolic measures were analyzed by gender and age. Results: Female gender was associated with divorced (χ2=5.3, d.f.=1, p=0.03) or widowed (χ2=8.1, d.f.=1, p=<0.01) marital status. Co-morbid anxiety disorders were more common in females than males (χ2=4.9, d.f.=1, p=0.03). Hallucinations(χ2=7.8, d.f.=1, p=0.005) and delusions with disorganization (t-test= −2.10, d.f. =257, p=0.04) were significantly associated with female gender as were higher cholesterol measures( χ2=7.15, d.f.=1, p=0.008).There were no significant interactions between treatment and gender in terms of change in BMI. Gender was not associated with treatment response. Discussion: This is the first analysis of gender and age as predictors of treatment outcome and treatment-associated changes in BMI and metabolic adverse effects in psychotic depression. Gender differences exist in patients with psychotic depression, most notably the presence of hallucinations. Female gender was associated with metabolic measures. Future studies with larger sample sizes may detect small gender differences in treatment outcome and treatment-associated changes in BMI and metabolic measures in psychotic depression. PMID:24229753

Tinea capitis is a dermatophytosis with diverse clinical manifestations. The causative fungi of tinea capitis vary with geography and time. This study aimed to identify the etiologic agents and to determine the clinico-etiologic correlation of tinea capitis in Lahore, Pakistan. From clinically suspected cases of tinea capitis, skin scrapings and hair samples were taken and subjected to microscopy and culture. Of 100 evaluable patients, 95% were children below 12 years of age with almost equal sex incidence. Noninflammatory and inflammatory lesions were seen in 56.4% and 43.6%, respectively. Trichophyton violaceum was the most common etiologic agent, responsible for 82% of infection, followed by T. tonsurans (8%), T. verrucosum (5%), and T. mentagrophytes (5%). T. violaceum is the predominant pathogen causing tinea capitis in this part of the world, and gives rise to a varied clinical picture.

Microflora of urinary tract was studied in 419 children aged 1 - 17 years and hospitalized due to acute or chronic pyelonephritis. Etiology of inflammatory process was established in 57.8% of cases. According to our study, etiologic structure of causative agents of pyelonephritis did not differ from all-Russian data. The leading positions belonged to Gram-negative microorganisms from Enterobacteriaceae family: Escherichia coli, Proteus mirabilis, and Klebsiella spp. Results of the study point to high susceptibility of main causative agents of pyelonephritis to cephalosporins, aminoglycosides, and fluoroquinolones. High resistance to aminopenicillines was noted. In several isolates from Enterobacteriaceae family significant resistance to nalidixic acid and furazidin was observed.

To analyze the clinical characteristics of acute meningitis and their relationship with age in adult patients presenting to the emergency department. We retrospectively investigated consecutive adult patients admitted with a diagnosis of bacterial or viral meningitis from 2002 to 2006. Data about patient's history, symptoms and signs at presentation, etiology and clinical course were collected. To investigate the relationship of clinical presentation with age, we divided patients in four age quartiles (<30 years, between 30 and 36 years, between 37 and 56 years, >56 years). Among the 202 patients considered in the study (mean age 42.8 ± 18.7 years, range 14-90), 162 (80.2%) patients had viral and 40 (19.8%) bacterial meningitis. Specific signs, such as neck stiffness or Kernig or Brudzinski signs, were more common in the first than in the fourth quartile (73.1 vs. 45.7% P = 0.041). Conversely, altered consciousness expressed as Glasgow Coma Scale (GCS) <15 was more frequent in the fourth (80.4%) than in the first (9.6%) quartile (P < 0.001). The linear regression analysis confirmed a significant decrease of GCS with the increasing of patient's age (r = -0.69, P < 0.001). At multivariate analysis, aging was associated with altered level of consciousness (OR 16.7, P < 0.001) independent of viral or bacterial etiology of the presence of comorbidities and of clinical severity (presence of severe sepsis or septic shock). Meningitis presentation largely differs with aging in adult patients. Level of consciousness is frequently altered in the older patients, when other specific signs become more rare, independent of etiology, comorbidities and clinical severity.

Variation in Subjective Aging by Sexual Minority Status.

PubMed

Barrett, Anne; Barbee, Harry

2017-06-01

The past few decades have seen increased scholarly attention to gay and lesbian individuals' aging experiences; however, few studies examine differences in subjective aging by sexual minority status. We identify four perspectives on the association between sexual minority status and subjective aging-double jeopardy, crisis competence, gender interactive, and limited salience perspectives. We examine each perspective's predictions using data from the first wave of Midlife in the United States (1995-1996; MIDUS). Ordinary least square regression models reveal strongest support for the limited salience perspective, suggesting that sexual minority status has weaker effects on subjective aging than do other social factors, such as age, health, and gender. However, some results provide support for the gender interactive perspective, positing that the effect of sexual minority status on subjective aging varies by gender. Our study provides an organizational framework of theoretical perspectives that can guide further examinations of variation in aging experiences by sexual minority status.

This study reports the effects of age and gender on the surface electromyogram while performing isometric contraction. Experiments were conducted with two age groups--Young (Age: 20-29) and Old (Age: 60-69) where they performed sustained isometric contractions at various force levels (50%, 75%, 100% of maximum voluntary contraction). Traditional features such as root mean square (RMS) and median frequency (MDF) were computed from the recorded sEMG. The result indicates that the MDF of sEMG was not significantly affected by age, but was impacted by gender in both age groups. Also there was a significant change in the RMS of sEMG with age and gender at all levels of contraction. The results also indicate a large inter-subject variation. This study will provide an understanding of the underlying physiological effects of muscle contraction and muscle fatigue in different cohorts.

Sarcoidosis is a systemic granulomatous disorder of unknown etiology often involving skin. Studies on cutaneous sarcoidosis and comorbidities are limited. This study is aimed to describe the clinical features of cutaneous sarcoidosis diagnosed in our hospital and to determine the relationships between cutaneous sarcoidosis and comorbidities.This retrospective study evaluates patients with cutaneous sarcoidosis in a tertiary center in Taiwan from 1996 to 2015. The records of 38 patients with cutaneous sarcoidosis were reviewed for clinical characteristics and evaluated by analysis of variance. A 1:4 case-control analysis was conducted with 152 age- and sex-matched controls who underwent biopsy for other benign skin tumors.The male to female ratio was 1:4.4. The average age at diagnosis was 51.7 years. Female patients were on average 13.9 years older than male patients. The correlation of age with gender was statistically significant (P = .037). The most common cutaneous lesions were plaques (47.4%) and confined to the face (71.1%). Of the 38 patients, 26.3% had diabetes mellitus. Age over 40 (P = .014) and female (P = .014) were associated with facial involvement. In the case-control study, a higher percentage of patients with cutaneous sarcoidosis than of control subjects had diabetes mellitus (P = .001), hearing loss (P = .031) and eye diseases (P = .047).The present study demonstrates a striking female predominance and high proportions of facial involvement. Diabetes mellitus, hearing loss, and eye diseases may be associated with Taiwanese patients with cutaneous sarcoidosis.

Purpose: Gender-affirming surgeries and hormone therapy are medically necessary treatments to alleviate gender dysphoria; however, significant gaps exist in the research and clinical literature on surgery utilization and age of hormone therapy initiation among transgender adults. Methods: We conducted a retrospective review of electronic health record data from a random sample of 201 transgender patients of ages 18-64 years who presented for primary care between July 1, 2010 and June 30, 2015 (inclusive) at an urban community health center in Boston, MA. Fifty percent in our analyses were trans masculine (TM), 50% trans feminine, and 24% reported a genderqueer/nonbinary gender identity. Regression models were fit to assess demographic, gender identity-related, sexual history, and mental health correlates of gender-affirming surgery and of age of hormone therapy initiation. Results: Overall, 95% of patients were prescribed hormones by their primary care provider, and the mean age of initiation of masculinizing or feminizing hormone prescriptions was 31.8 years (SD=11.1). Younger age of initiation of hormone prescriptions was associated with being TM, being a student, identifying as straight/heterosexual, having casual sexual partners, and not having past alcohol use disorder. Approximately one-third (32%) had a documented history of gender-affirming surgery. Factors associated with increased odds of surgery were older age, higher income levels, not identifying as bisexual, and not having a current psychotherapist. Conclusion: This study extends our understanding of prevalence and factors associated with gender-affirming treatments among transgender adults seeking primary care. Findings can inform future interventions to expand delivery of clinical care for transgender patients.

The effect of rotavirus in developed countries is mainly economic. This study aimed to assess the indirect costs induced by rotavirus acute gastroenteritis (RVAGE) in Spain. A prospective observational study was conducted from October 2008 to June 2009. It included 682 children up to 5 years of age with acute gastroenteritis (AGE) who attended primary care (n = 18) and emergency room/hospital settings (n = 10), covering the regions of Galicia and Asturias (North-west Spain). All non-medical expenses incurred throughout the episode were recorded in detail using personal interviews and telephone contact. Among the 682 enrolled children, 207 (30.4%) were rotavirus positive and 170 (25%) had received at least one dose of rotavirus vaccine. The mean (standard deviation) indirect cost caused by an episode of AGE was estimated at 135.17 (182.70) Euros. Costs were 1.74-fold higher when AGE was caused by rotavirus compared with other etiologies: 192.7 (219.8) Euros vs. 111.6 (163.5) Euros (p < .001). The costs for absenteeism were the most substantial with a mean of 91.41 (134.76) Euros per family, resulting in a loss of 2.45 (3.17) days of work. In RVAGE patients, the absenteeism cost was 120.4 (154) Euros compared with 75.8 (123) for the other etiologies (p = .002), because of loss of 3.5 (3.6) vs 1.9 (2.9) days of work (p < .001). Meals costs were 2-fold-higher (48.5 (55) vs 24.3 (46) Euros, p < .001) and travel costs were 2.6-fold-higher (32 (92) vs 12.5 (21.1) Euros, p = .005) in RVAGE patients compared with those with other etiologies. There were no differences between RVAGE and other etiologies groups regarding costs of hiring of caregivers or purchase of material. Patients with RVAGE were admitted to hospital more frequently than those with other etiologies (47.8% vs 14%, p < .001). Rotavirus generates a significant indirect economic burden. Our data should be considered in the decision-making process of the eventual inclusion of rotavirus vaccine in the national immunization schedule of well developed countries.

To determine the relative and absolute reliability of a dual-task functional mobility assessment. Cross-sectional study. Academic rehabilitation hospital. Individuals (N=60) with lower extremity amputation attending an outpatient amputee clinic (mean age, 58.21±12.59y; 18, 80% male) who were stratified into 3 groups: (1) transtibial amputation of vascular etiology (n=20); (2) transtibial amputation of nonvascular etiology (n=20); and (3) transfemoral or bilateral amputation of any etiology (n=20). Not applicable. Time to complete the L Test measured functional mobility under single- and dual-task conditions. The addition of a cognitive task (serial subtractions by 3's) created dual-task conditions. Single-task performance on the cognitive task was also reported. Intraclass correlation coefficients (ICCs) measured relative reliability; SEM and minimal detectable change with a 95% confidence interval (MDC 95 ) measured absolute reliability. Bland-Altman plots measured agreement between assessments. Relative reliability results were excellent for all 3 groups. Values for the dual-task L Test for those with transtibial amputation of vascular etiology (n=20; mean age, 60.36±7.84y; 19, 90% men) were ICC=.98 (95% confidence interval [CI], .94-.99), SEM=1.36 seconds, and MDC 95 =3.76 seconds; for those with transtibial amputation of nonvascular etiology (n=20; mean age, 55.85±14.08y; 17, 85% men), values were ICC=.93 (95% CI, .80-.98), SEM=1.34 seconds, and MDC 95 =3.71 seconds; and for those with transfemoral or bilateral amputation (n=20; mean age, 58.21±14.88y; 13, 65% men), values were ICC=.998 (95% CI, .996-.999), SEM=1.03 seconds, and MDC 95 =2.85 seconds. Bland-Altman plots indicated that assessments did not vary systematically for each group. This dual-task assessment protocol achieved approved levels of relative reliability values for the 3 groups tested. This protocol may be used clinically or in research settings to assess the interaction between cognition and functional mobility in the population with lower extremity amputation.

Although early childhood is a period of rapid neurocognitive development, few studies have assessed neuropsychological functioning in various cognitive domains in young typically developing children. Also, results regarding its association with gender and intelligence are mixed. In 853 typically developing children aged 6 to 10 years old, the association of gender, age, and intelligence with neuropsychological functioning in the domains of attention, executive functioning, language, memory, sensorimotor functioning, and visuospatial processing was explored. Clear positive associations with age were observed. In addition, gender differences were found and showed that girls generally outperformed boys, with the exception of visuospatial tasks. Furthermore, IQ was positively associated with neuropsychological functioning, which was strongest in visuospatial tasks. Performance in different neuropsychological domains was associated with age, gender, and intelligence in young typically developing children, and these factors should be taken into account when assessing neuropsychological functioning in clinical or research settings.

Rigidity in Gender-Typed Behaviors in Early Childhood: A Longitudinal Study of Ethnic Minority Children

Ruble, Diane; Tamis-LeMonda, Catherine; Shrout, Patrick E.

2014-01-01

A key prediction of cognitive theories of gender development concerns developmental trajectories in the relative strength or rigidity of gender typing. To examine these trajectories in early childhood, 229 children (African American, Mexican, Dominican) were followed annually from age 3 to 5 and gender-stereotypical appearance, dress-up play, toy play, and sex segregation were examined. High gender-typing was found across ethnic group, and most behaviors increased in rigidity, especially from age 3 to 4. In addressing controversy surrounding the stability and structure of gender-typing it was found that from year to year, most behaviors showed moderately stable individual differences. Behaviors were uncorrelated within age, but showed more concordance in change across time, suggesting that aspects of gender-typing are multidimensional but still show coherence. PMID:23432471

The importance of childhood and adulthood aspects of gendered life for adult mental ill-health symptoms – a 27-year follow-up of the Northern Swedish Cohort

PubMed Central

2012-01-01

Background The increasing gender equality during the 20th century, mainly in the Nordic countries, represents a major social change. A well-established theory is that this may affect the mental health patterns of women and men. This study aimed at examining associations between childhood and adulthood gendered life on mental ill-health symptoms. Methods A follow-up study of a cohort of all school leavers in a medium-sized industrial town in northern Sweden was performed from age 16 to age 42. Of those still alive of the original cohort, 94% (n = 1007) participated during the whole period. Gendered life was divided into three stages according to whether they were traditional or non-traditional (the latter includes equal): childhood (mother’s paid work position), adulthood at age 30 (ideology and childcare), and adulthood at age 42 (partnership and childcare). Mental ill-health was measured by self-reported anxious symptoms (“frequent nervousness”) and depressive symptoms (“frequent sadness”) at age 42. The statistical method was logistic regression analysis, finally adjusted for earlier mental ill-health symptoms and social confounding factors. Results Generally, parents’ gendered life was not decisive for a person’s own gendered life, and adulthood gender position ruled out the impact of childhood gender experience on self-reported mental ill-health. For women, non-traditional gender ideology at age 30 was associated with decreased risk of anxious symptoms (76% for traditional childhood, 78% for non-traditional childhood). For men, non-traditional childcare at age 42 was associated with decreased risk of depressive symptoms (84% for traditional childhood, 78% for non-traditional childhood). A contradictory indication was that non-traditional women in childcare at age 30 had a threefold increased risk of anxious symptoms at age 42, but only when having experienced a traditional childhood. Conclusion Adulthood gender equality is generally good for self-reported mental health regardless of whether one opposes or continues one’s gendered history. However, the childcare findings indicate a differentiated picture; men seem to benefit in depressive symptoms from embracing this traditionally female duty, while women suffer anxious symptoms from departing from it, if their mother did not.

Sarcoidosis is a multisystem granulomatous disease of unknown etiology. It may occur at any age, but is most commonly seen in young to middle age adults. Sarcoidosis remains more common in women regardless of geographic or racial boundaries. Although the etiology remains unclear, the most common explanation is that sarcoidosis is a disease of immunologic dysregulation triggered by an as yet unidentified environmental or microbial antigen in genetically susceptible persons. We review a case of sarcoidosis with was initially diagnosed in a neck lymph node that was removed for evaluation of metastatic squamous cell carcinoma with a discussion on the clinical and histologic characteristic of the disease.

Shared etiology of phonological memory and vocabulary deficits in school-age children.

Peterson, Robin L; Pennington, Bruce F; Samuelsson, Stefan; Byrne, Brian; Olson, Richard K

2013-08-01

The goal of this study was to investigate the etiologic basis for the association between deficits in phonological memory (PM) and vocabulary in school-age children. Children with deficits in PM or vocabulary were identified within the International Longitudinal Twin Study (ILTS; Samuelsson et al., 2005). The ILTS includes 1,045 twin pairs (between the ages of 5 and 8 years) from the United States, Australia, and Scandinavia. The authors applied the DeFries-Fulker ( DeFries & Fulker, 1985, 1988) regression method to determine whether problems in PM and vocabulary tend to co-occur because of overlapping genes, overlapping environmental risk factors, or both. Among children with isolated PM deficits, the authors found significant bivariate heritability of PM and vocabulary weaknesses both within and across time. However, when probands were selected for a vocabulary deficit, there was no evidence for bivariate heritability. In this case, it appears that the PM-vocabulary relationship is caused by common shared environmental experiences. The findings are consistent with previous research on the heritability of specific language impairment and suggest that there are etiologic subgroups of children with low vocabulary for different reasons, 1 being more influenced by genes and another being more influenced by environment.

The antisaccade task is a widely used technique to measure failure of inhibition, an important cause of cognitive and clinical abnormalities found in schizophrenia. Although antisaccade performance, which reflects the ability to inhibit prepotent responses, is a putative schizophrenia endophenotype, researchers have not consistently reported the expected differences between first-degree relatives and comparison groups. Schizophrenia participants (n=219) from the large Consortium on the Genetics of Schizophrenia (COGS) sample (n=1078) demonstrated significant deficits on an overlap version of the antisaccade task compared to their first-degree relatives (n=443) and community comparison subjects (CCS; n=416). Although mean antisaccade performance of first-degree relatives was intermediate between schizophrenia participants and CCS, a linear mixed-effects model adjusting for group, site, age, and gender found no significant performance differences between the first-degree relatives and CCS. However, admixture analyses showed that two components best explained the distributions in all three groups, suggesting two distinct doses of an etiological factor. Given the significant heritability of antisaccade performance, the effects of a genetic polymorphism is one possible explanation of our results.

Decreased Phosphorylated Protein Kinase B (Akt) in Individuals with Autism Associated with High Epidermal Growth Factor Receptor (EGFR) and Low Gamma-Aminobutyric Acid (GABA).

Russo, Anthony J

2015-01-01

Dysregulation of the PI3K/AKT/mammalian target of rapamycin (mTOR) pathway could contribute to the pathogenesis of autism spectrum disorders. In this study, phosphorylated Akt concentration was measured in 37 autistic children and 12, gender and age similar neurotypical, controls using an enzyme-linked immunosorbent assay. Akt levels were compared to biomarkers known to be associated with epidermal growth factor receptor (EGFR) and c-Met (hepatocyte growth factor (HGF) receptor) pathways and severity levels of 19 autism-related symptoms. We found phosphorylated Akt levels significantly lower in autistic children and low Akt levels correlated with high EGFR and HGF and low gamma-aminobutyric acid, but not other biomarkers. Low Akt levels also correlated significantly with increased severity of receptive language, conversational language, hypotonia, rocking and pacing, and stimming, These results suggest a relationship between decreased phosphorylated Akt and selected symptom severity in autistic children and support the suggestion that the AKT pathways may be associated with the etiology of autism.

Alcohol-impaired driving among college students represents a significant public health concern, yet little is known about specific theoretical and individual difference risk factors for driving after drinking among heavy drinking college students. This study evaluated the hypothesis that heavy drinkers with elevated alcohol demand would be more likely to report drinking and driving. Participants were 207 college students who reported at least 1 heavy drinking episode (4/5 or more drinks in 1 occasion for a woman/man) in the past month. Participants completed an alcohol purchase task that assessed hypothetical alcohol consumption across 17 drink prices and an item from the Young Adult Alcohol Consequences Questionnaire that assessed driving after drinking. In binary logistic regression models that controlled for drinking level, gender, ethnicity, age, and sensation seeking, participants who reported higher demand were more likely to report driving after drinking. These results provide support for behavioral economics models of substance abuse that view elevated/inelastic demand as a key etiological feature of substance misuse.

Otitis media (OM) is considered a potentially severe disease due to the risk of complications. To establish the annual incidence of intratemporal complications (ITC) resulting from OM and to prospectively assess patients for epidemiological and clinical factors. This prospective cohort study included patients admitted during one year at a university hospital diagnosed with intratemporal complications of OM. Patients were analyzed for age, gender, type of intratemporal complication, treatment, and clinical outcome. The overall incidence of complications and the specific incidence rates of each type of complication were determined. 1,816 patients were diagnosed with OM; 592 (33%) had chronic OM; 1224 (67%) had acute OM. Fifteen patients were diagnosed with OM ITC, adding up to an annual incidence of 0.8%. Nineteen diagnoses of ITC were made in 15 patients. Seven (36.8%) patients were diagnosed with labyrinthine fistula, five (26.3%) with mastoiditis, four (21.1%) with peripheral facial palsy, and three (15.8%) with labyrinthitis. The incidence of intratemporal complications remains significant when compared to the rates seen in developed countries. Chronic cholesteatomatous otitis media is the most frequent etiology of intratemporal complications. Labyrinthine fistula is the most common intratemporal complication.

The present study examined the patterns and sources of 10-year stability and change of adult personality assessed by the 5 domains and 30 facets of the Revised NEO Personality Inventory. Phenotypic and biometric analyses were performed on data from 126 identical and 61 fraternal twins from the Bielefeld Longitudinal Study of Adult Twins (BiLSAT). Consistent with previous research, LGM analyses revealed significant mean-level changes in domains and facets suggesting maturation of personality. There were also substantial individual differences in the change trajectories of both domain and facet scales. Correlations between age and trait changes were modest and there were no significant associations between change and gender. Biometric extensions of growth curve models showed that 10-year stability and change of personality were influenced by both genetic as well as environmental factors. Regarding the etiology of change, the analyses uncovered a more complex picture than originally stated, as findings suggest noticeable differences between traits with respect to the magnitude of genetic and environmental effects.

Co-occurrence of oral language disorders and enuresis in children. To identify and analyze the relationship between instances of oral language disorders and enuresis in children. Clinical, quantitative and qualitative study, with a descriptive/interpretative outline, presented through two distinct situations. "Situation 1" refers to a group of 120 children between 3:0 and 10:0 years old, independently of gender and age, from a philanthropic Institution in Greater São Paulo. "Situation 2" refers specifically to the evaluation of children who have oral language disorders and enuresis. Results indicated that enuretic children present a higher percentage of oral language disorders when compared to non-enuretic children, especially phonological disorders and talking very little. These results support the studies on co-occurrence of enuresis and oral language disorders, presented in papers that attribute a bio-psychic etiology to this co-morbidity. Results indicated a relationship between enuresis and oral language disorders. Considering the interactions among language, body and psyche, it is suggested that speech therapists, when dealing with oral language disorders in children, also investigate the acquisition of their bladder sphincter control, in a bio-psychical approach.

The aim of this paper is to identify the early and late implications of JPDD for biliary pathology, as well as for endoscopic therapy and classical surgery dealing mainly with lithiasis. This paper is based on a retrospective study comprising a number of 675 ERCP performed on 601 patients between 1997-2007, out of which 399 cases were followed by therapeutic measures. A total of 79 procedures were performed on 65 cases with JPDD. The main criteria were: gender, age, indications regarding the performance of ERCP+/-ES, complications that occurred while carrying out these procedures. In all the cases examined (601) the percentage of JPDD reported was of 10.81%. The rate of complications in the sphincterotomized patients without JPDD was 5.75% and the rate in the sphincterotomized patients with JPDD was 14.89%. In conclusion, the paper discusses the clinical and therapeutic implications of JPDD in biliary pathology. It has been found that JPDD is an important etiological cause for the late diseases occurring after cholelithiasis surgery. JPDD also leads to immediate therapeutic implications such as: difficult cannulation and high incidence of ERCP+/-ES complications.

The association of variants in CLU, CR1, PICALM, BIN1, ABCA7, and CD33 genes with late-onset Alzheimer's disease (LOAD) was evaluated and confirmed through genome-wide association study. However, it is unknown whether these associations can be replicated in admixed populations. The association of 14 single-nucleotide polymorphisms in those genes was evaluated in 280 LOAD cases and 357 controls from the Colombian population. In a multivariate analysis using age, gender, APOE∊4 status, and admixture covariates, significant associations were obtained ( P < .05) for variants in BIN1 (rs744373, odds ratio [OR]: 1.42), CLU (rs11136000, OR: 0.66), PICALM (rs541458, OR: 0.69), ABCA7 (rs3764650, OR: 1.7), and CD33 (rs3865444, OR: 1.12). Likewise, a significant interaction effect was observed between CLU and CR1 variants with APOE. This study replicated the associations previously reported in populations of European ancestry and shows that APOE variants have a regulatory role on the effect that variants in other loci have on LOAD, reflecting the importance of gene-gene interactions in the etiology of neurodegenerative diseases.

To determine the efficacy of L-ornithine-L-aspartate in treatment of hepatic encephalopathy. Randomized, placebo-controlled trial. Department of Gastroenterology and Hepatology, Sheikh Zayed Hospital, Lahore, from February to August 2005. Cirrhotic patients with hyperammonemia and overt hepatic encephalopathy were enrolled. Eighty patients were randomized to two treatment groups, L-ornithine-L-aspartate (20 g/d) or placebo, both dissolved in 250 mL of 5% dextrose water and infused intravenously for four hours a day for five consecutive days with 0.5 g/kg dietary protein intake at the end of daily treatment period. Outcome variables were postprandial blood ammonia and mental state grade. Adverse reactions and mortality were also determined. Both treatment groups were comparable regarding age, gender, etiology of cirrhosis, Child-Pugh class, mental state grade and blood ammonia at baseline. Although, improvement occurred in both groups, there was a greater improvement in L-ornithine-L-aspartate group with regard to both variables. Four patients in the placebo group and 2 in L-ornithine-L-aspartate group died. L-ornithine-L-aspartate infusions were found to be effective in cirrhotic patients with hepatic encephalopathy.

Previous studies indicate disturbed olfactory functions in anorexia nervosa with presumable relationship to the clinical symptom of food aversion and weight loss. However, these studies are in part limited due to inadequately matched control samples, insufficient exclusion criteria, complex interactions of the olfactory and trigeminal system, and the lack of regard to co-morbidity and medication. Thus, we investigated olfactory function in 26 female adolescent patients with anorexia nervosa and 23 healthy controls matched for age, gender, handedness, and intelligence. No significant group differences were identified. Controlling for co-morbid disorders, psychopharmacological treatment, and depressivity revealed superior olfactory identification performance in the "pure" anorexia nervosa group (n = 15) in contrast to the controls. Superior identification may be mediated by increased attentional processes towards food stimuli in patients with anorexia nervosa. Effects of co-morbidity and medication highlight the role of neurobiological factors in the etiology of anorexia nervosa. Furthermore, as other neuropsychiatric disorders such as Parkinson's disease or attention deficit hyperactivity disorder show distinct olfactory function patterns, olfaction may be suitable as phenotypic marker with potential relevance for (differential) diagnosis in neuropsychiatric disorders.

This study examined age and gender differences in physical activity levels and various physical activity patterns of 11-14-year-old Turkish adolescents and also determined if these differ between genders. Six hundred and fifty girls and 666 boys between the ages of 11 and 14 years constituted the sample of this study. Participants self-reported physical activity levels and patterns were determined by a Weekly Activity Checklist. A 2 x 4 (Gender x Age) MANOVA revealed overall significant main effect of gender and age on the physical activity level of adolescents; however, gender x age interaction effect was not significant. The findings indicated an interaction effect was not significant. The findings indicated an age-related decline in physical activity level, an increase in participation in low activities, and a decrease in participation in moderate and vigorous activities in 11-14-year-old Turkish adolescents. In addition it was found that boys were more active than girls and participated more in moderate and vigorous activities.

This paper investigates potential gender and age differences in conviction and crash occurrence subsequent to being directed to attend Iowa's Driver Improvement Program (DIP). Binary logit models were developed to investigate the factors that influence conviction occurrence after DIP by gender and age. Because of the low crash occurrence subsequent to DIP, association rules were applied to investigate the factors that influence crash occurrence subsequent to DIP, in lieu of econometric models. There were statistical significant differences by driver gender, age, and conviction history in the likelihood of subsequent convictions. However, this paper found no association between DIP outcome, crash history, and crash occurrence. Evaluating the differences in conviction and crash occurrence subsequent to DIP between female and male drivers, and among different age groups can lead to improvements of the effectiveness of DIPs and help to identify low-cost intervention measures, customized based on drivers' gender and age, for improving driving behaviors.

Age and sex-related changes in the pattern of fractures and concomitant injuries observed in this patient population is helpful in understanding craniofacial development and the treatment of these unique injuries. The goal of this study was to examine all facial fractures occurring in a child and adolescent population (age 18 or less) at a trauma center to determine any age or sex-related variability amongst fracture patterns and concomitant injuries. All facial fractures occurring at a trauma center were collected over a 12-year period based on International Classification of Disease, rev. 9 codes. This was delimited to include only those patients 18 years of age or younger. Age, sex, mechanism, and fracture types were collected and analyzed. During this time period, there were 3147 patients with facial fractures treated at our institution, 353 of which were in children and adolescent patients. Upon further review 68 patients were excluded due to insufficient data for analysis, leaving 285 patients for review, with a total of 431 fractures. The most common etiology of injury was assault for males and motor vehicle accidents (MVA) for females. The most common fracture was of the mandible in males and of the orbit in females. The most common etiology in younger age groups includes falls and pedestrian struck. Older age groups exhibit a higher incidence of assault-related injuries. Younger age groups showed a propensity for orbital fractures as opposed to older age groups where mandibular fractures predominated. Intracranial hemorrhage was the most common concomitant injury across most age groups. The differences noted in etiology of injury, fracture patterns, and concomitant injuries between sexes and different age groups likely reflects the differing activities that each group engages in predominantly. In addition the growing facial skeleton offers varying degrees of protection to the cranial contents as force-absorbing mechanisms develop.

Lung cancer is the leading cause of cancer mortality worldwide. Tobacco smoking is its primary cause, and yet the precise molecular alterations induced by smoking in lung tissue that lead to lung cancer and impact survival have remained obscure. A new framework of research is needed to address the challenges offered by this complex disease. We designed a large population-based case-control study that combines a traditional molecular epidemiology design with a more integrative approach to investigate the dynamic process that begins with smoking initiation, proceeds through dependency/smoking persistence, continues with lung cancer development and ends with progression to disseminated disease or response to therapy and survival. The study allows the integration of data from multiple sources in the same subjects (risk factors, germline variation, genomic alterations in tumors, and clinical endpoints) to tackle the disease etiology from different angles. Before beginning the study, we conducted a phone survey and pilot investigations to identify the best approach to ensure an acceptable participation in the study from cases and controls. Between 2002 and 2005, we enrolled 2101 incident primary lung cancer cases and 2120 population controls, with 86.6% and 72.4% participation rate, respectively, from a catchment area including 216 municipalities in the Lombardy region of Italy. Lung cancer cases were enrolled in 13 hospitals and population controls were randomly sampled from the area to match the cases by age, gender and residence. Detailed epidemiological information and biospecimens were collected from each participant, and clinical data and tissue specimens from the cases. Collection of follow-up data on treatment and survival is ongoing. EAGLE is a new population-based case-control study that explores the full spectrum of lung cancer etiology, from smoking addiction to lung cancer outcome, through examination of epidemiological, molecular, and clinical data. We have provided a detailed description of the study design, field activities, management, and opportunities for research following this integrative approach, which allows a sharper and more comprehensive vision of the complex nature of this disease. The study is poised to accelerate the emergence of new preventive and therapeutic strategies with potentially enormous impact on public health.

An Epidemiological Perspective of Obsessive-Compulsive Disorder in Children and Adolescents

2003-01-01

Obsessive-compulsive disorder (OCD) is reviewed from an epidemiological perspective. OCD is defined according to the DSM-IV and ICD-10, with differences noted between these two classification systems. The epidemiological rubrics of quantity (prevalence), location (genetic methods and gender differences), cause (genetic etiology), and causal mechanisms (natural history and clinical course) are reviewed. The review concludes that more research is needed to further understand the epidemiology of OCD in children and adolescents, both from a Canadian and worldwide perspective. PMID:19030478

The impact of age vs. life experience on the gender role attitudes of women in different cohorts.

Lynott, P P; McCandless, N J

2000-01-01

Much research has concluded that the gender role attitudes of older women are more traditional in orientation. This line of research, however, has often confounded the impact of age and cohort. Consequently, cohort differences in life experiences have not been systematically explored. This study addresses the relationship between age and gender role attitudes, taking into account the potential mediating effects of life experiences and controlling for cohort. The conclusions suggest that the impact of age on gender role attitudes is not as strong as might be expected. Rather, the results show that the life experiences of different cohorts are better predictors of gender role attitudes among older women, though such experiences do not have the same impact on all women.

Background and aims. Early Childhood Caries (ECC) is a public health problem with biological, social and behavioural determinants and the notion that the principal etiology is inappropriate feeding modalities is no longer tenable. Hence this study was undertaken to assess the relationship between ECC and socio-demographic factors, dietary habits, oral hygiene habits and parental characteristics. Materials and methods. The study involved a dental examination of 1400 children aged 0-71 months, recording caries using Gruebbel’s deft index and a structured questionnaire to interview parents or caretakers. The tabulated data was statistically analyzed using t-test and ANOVA at 5% level of significance. Results. The variables significantly associated with ECC were age (P<0.001), geographical location (P<0.05), duration of breast/bottle feeding (P<0.001), use of sweetened pacifiers (P<0.001), frequency of snacking (P<0.05), frequency of tooth brushing (P<0.001), the person responsible for child’s oral health care (P<0.05) and education level of parents (P<0.05). However, other variables like child’s gender, number of siblings, types of snack the child preferred and age at which tooth brushing was instituted did not have statistically significant relationship with ECC (P>0.05). Conclusion. ECC is preventable and manageable with proper information and skills. It is important for healthcare professionals, family physicians and parents to be cognizant of the involved risk factors as their preventive efforts represent the first line of defense.

Background. Cognitive impairment is an important clinical issue among elderly patients with depression and has a more complex etiology because of the variable rate of neurodegenerative changes associated with depression. The aim of the present work was to examine the prevalence of cognitive impairment and depression in a representative sample of adults aged ≥60 years. Methods. The presented work was a cross-sectional study on the prevalence of cognitive impairment and depression. Door-to-door interview technique was assigned in condition with multistage probability random sampling to obtain subjects that represent a population of the Guadalajara metropolitan area (GMA), Mexico. Cognitive function and depression were assessed by applying standardized Mini-Mental State Examination of Folstein (MMSE) and the Geriatric Depression Scale (GDS), respectively. Results. Prevalence of cognitive impairment was 13.8% (14.5% women, 12.6% men); no significant differences by gender and retired or pensioner were found. Prevalence of depression was 29.1% (33.6% women, 21.1% men); no significant differences by retired or pensioner were found. Cognitive impairment was associated with depression (OR  =  3.26, CI 95%, 2.31-4.60). Prevalence of cognitive impairment and depression is associated with: being woman, only in depression being older than 75 years being married, and a low level of education. Conclusion. Cognitive impairment and depression are highly correlated in adults aged ≥60.

Many persons who survived Nazi concentration camps are now in advanced age, so that rehabilitation centers in Poland are seeing increasing numbers of such patients, especially after strokes. In many cases, the process of rehabilitation is severely hampered by Post-Traumatic Stress Disorder (PTSD), while the neuropsychological consequences of the stroke itself often evoke traumatic memories and simultaneously disorganize or destroy the patient's previous coping mechanisms. The present study describes the program developed by the authors for concentration camp survivors in post-stroke rehabilitation, including the use of art therapy and specially prepared films to help the patients cope with PTSD. The experimental group (KL) consisted of 8 such patients (4 men, 4 women, average age 79.1+/-4.28) with mild post-stroke aphasia who went through the PTSD program, while the comparison group (C) included 8 post-stroke patients, matched for age and gender, who were not concentration camp survivors and showed no premorbid symptoms of PTSD. All subjects were tested at baseline and again 3 months later, using structured interview and observation, self-rating scales for three basic negative emotions (anger, anxiety and sadness) and the Frustration and Aggression Test for the Disabled. The results showed significant differences between the groups at baseline, while at follow-up the differences between groups had changed in both extent and distribution. Qualitative analysis of the results allows for some important observations about the etiology and course of PTSD in these persons.

Involvement of agrochemicals have been suggested in the development of chronic kidney disease of unknown etiology (CKDu). The association between CKDu and blood level of organochlorine pesticides (OCPs) in CKDu patients has been examined in the present study. All the recruited study subjects (n = 300) were divided in three groups, namely, healthy control (n = 100), patients with chronic kidney disease of unknown etiology (n = 100), and patients with chronic kidney disease of known etiology (CKDk) (n = 100). Blood OCP levels of all three study groups were analyzed by gas chromatography. Increased level of OCPs, namely α-HCH, aldrin, and β-endosulfan, were observed in CKDu patients as compared to healthy control and CKD patients of known etiology. The levels of these pesticides significantly correlated negatively with the estimated glomerular filtration rate (eGFR) and positively with urinary albumin of CKD patients. Logistic regression analysis revealed association of γ-HCH, p, p'-DDE, and β-endosulfan with CKDu on adjustment of age, sex, BMI, and total lipid content. Increased blood level of certain organochlorine pesticides is associated with the development of chronic kidney disease of unknown etiology.

Attribution theory suggests the hypothesis that heterosexuals' attitudes toward homosexual sexual orientation will be more negative when homosexuality is attributed to controllable causes. Our randomized study analyzed (a) whether beliefs about the genetic or environmental etiology of the homosexual sexual orientation can be immediately modified by reading a text and (b) the causal effect of attributions about the controllability (environmental etiology) or noncontrollability (genetic etiology) of homosexual sexual orientation on the rejection of same-sex parenting and their social rights. The sample was composed of 190 Spanish university students with a mean age of 22.07 years (SD = 8.46). The results show that beliefs about the etiology of the sexual orientation could be modified by means of a written text. Furthermore, participants who believed that sexual orientation had a genetic etiology showed greater support for social rights and less rejection of same-sex parenting. However, the effects were detected only when there was a traditional opposition to the family with same-sex parenting. When the opposition was normative, the effect was not statistically significant. Our results can be useful in planning variables for intervention programs designed to foster tolerance toward and normality of sexual diversity.

To assess the effect of gender, age and deprivation on key performance indicators in a colorectal cancer screening programme. Between March 2000 and May 2006 a demonstration pilot of biennial guaiac faecal occult blood test (gFOBT) colorectal screening was carried out in North-East Scotland for all individuals aged 50-69 years. The relevant populations were subdivided, by gender, into four age groups and into five deprivation categories according to the Scottish Index of Multiple Deprivation (SIMD), and key performance indicators analysed within these groups. In all rounds, uptake of the gFOBT increased with age (P < 0.001), decreased with increasing deprivation in both genders (P < 0.001), and was consistently higher in women than in men in all age and all SIMD groups. In addition, increasing deprivation was negatively associated with uptake of colonoscopy in men with a positive gFOBT (P < 0.001) although this effect was not observed in women. Positivity rates increased with age (P < 0.001) and increasing deprivation (P < 0.001) in both genders in all rounds, although they were higher in men than in women for all age and SIMD categories. Cancer detection rates increased with age (P < 0.001), were higher in men than in women in all age and SIMD categories, but were not consistently related to deprivation. In both genders, the positive predictive value (PPV) for cancer increased with age (P < 0.001) and decreased with increasing deprivation (P < 0.001) in all rounds and was consistently higher in men than in women in all age and SIMD categories. In this population-based colorectal screening programme gender, age, and deprivation had marked effects on key performance indicators, and this has implications both for the evaluation of screening programmes and for strategies designed to reduce inequalities.

The etiology of intimate partner violence (IPV) is multifactorial. However, etiological theories of IPV have rarely included potential genetic factors. The purpose of the present study was to examine whether a cumulative genetic score (CGS) containing the MAOA and 5-HTTLPR polymorphisms was associated with IPV perpetration after accounting for the effects of alcohol problems, drug problems, age, and length of relationship. We obtained DNA from 97 men in batterer intervention programs in the state of Rhode Island. In the full sample, the CGS was significantly associated with physical and psychological aggression and injuries caused to one's partner, even after controlling for the effects of alcohol problems, drug problems, age, and length of relationship. Two of the men in the sample likely had Klinefelter's syndrome and analyses were repeated excluding these two individuals, leading to similar results. The implications of the genetics findings for the etiology and treatment of IPV among men in batter intervention programs are briefly discussed. PMID:24759925

In this paper, we propose an age and gender estimation framework using the region-SIFT feature and multi-layered SVM classifier. The suggested framework entails three processes. The first step is landmark based face alignment. The second step is the feature extraction step. In this step, we introduce the region-SIFT feature extraction method based on facial landmarks. First, we define sub-regions of the face. We then extract SIFT features from each sub-region. In order to reduce the dimensions of features we employ a Principal Component Analysis (PCA) and a Linear Discriminant Analysis (LDA). Finally, we classify age and gender using a multi-layered Support Vector Machines (SVM) for efficient classification. Rather than performing gender estimation and age estimation independently, the use of the multi-layered SVM can improve the classification rate by constructing a classifier that estimate the age according to gender. Moreover, we collect a dataset of face images, called by DGIST_C, from the internet. A performance evaluation of proposed method was performed with the FERET database, CACD database, and DGIST_C database. The experimental results demonstrate that the proposed approach classifies age and performs gender estimation very efficiently and accurately.

We aimed to characterize the lasting effect of moderate caloric restriction during early pregnancy on offspring energy homeostasis, by focusing on the effects on food intake and body weight as well as on the insulin and leptin systems. Male and female offspring of 20% caloric restricted dams (from 1 to 12 days of pregnancy) (CR) and from control dams were studied. These animals were fed after weaning with a normal-fat (NF) diet until the age of 4 months, and then moved to a high-fat (HF) diet. Blood parameters were measured under fed and 14-h fasting conditions at different ages (2, 4 and 5 months). Food preferences were also assessed in adult animals. Accumulated caloric intake from weaning to the age of 5 months was higher in CR animals compared with their controls, and this resulted in higher body weight in adulthood in males, but not in females. Both male and female CR animals already showed higher insulin levels at the age of 2 months, under fed conditions, and higher HOMA-IR from the age of 4 months, compared with their controls. CR male animals, but not females, displayed higher preference for fat-rich food than their controls in adulthood and higher circulating leptin levels when they were under HF diet. It is suggested that hyperinsulinemia may play a role in the etiology of hyperphagia in the offspring of caloric restricted animals during gestation, with different outcomes on body weight depending on the gender, which could be associated with different programming effects on later leptin resistance.

2008-12-01

To establish the psychosexual outcome of gender-dysphoric children at 16 years or older and to examine childhood characteristics related to psychosexual outcome. We studied 77 children who had been referred in childhood to our clinic because of gender dysphoria (59 boys, 18 girls; mean age 8.4 years, age range 5-12 years). In childhood, we measured the children's cross-gender identification and discomfort with their own sex and gender roles. At follow-up 10.4 +/- 3.4 years later, 54 children (mean age 18.9 years, age range 16-28 years) agreed to participate. In this group, we assessed gender dysphoria and sexual orientation. At follow-up, 30% of the 77 participants (19 boys and 4 girls) did not respond to our recruiting letter or were not traceable; 27% (12 boys and 9 girls) were still gender dysphoric (persistence group), and 43% (desistance group: 28 boys and 5 girls) were no longer gender dysphoric. Both boys and girls in the persistence group were more extremely cross-gendered in behavior and feelings and were more likely to fulfill gender identity disorder (GID) criteria in childhood than the children in the other two groups. At follow-up, nearly all male and female participants in the persistence group reported having a homosexual or bisexual sexual orientation. In the desistance group, all of the girls and half of the boys reported having a heterosexual orientation. The other half of the boys in the desistance group had a homosexual or bisexual sexual orientation. Most children with gender dysphoria will not remain gender dysphoric after puberty. Children with persistent GID are characterized by more extreme gender dysphoria in childhood than children with desisting gender dysphoria. With regard to sexual orientation, the most likely outcome of childhood GID is homosexuality or bisexuality.

Boys vs. girls: Gender differences in the neural development of trust and reciprocity depend on social context.

Trust and cooperation increase from adolescence to adulthood, but studies on gender differences in this development are rare. We investigated gender and age-related differences in trust and reciprocity and associated neural mechanisms in 43 individuals (16-27 years, 22 male). Participants played two multi-round trust games with a cooperative and an unfair partner. Males showed more basic trust towards unknown others than females. Both genders increased trust during cooperative interactions, with no differences in average trust. Age was unrelated to trust during cooperation. During unfair interactions males decreased their trust more with age than females. ROI analysis showed age-related increases in activation in the temporo-parietal junction (TPJ) and dorsolateral prefrontal cortex (dlPFC) during cooperative investments, and increased age-related caudate activation during both cooperative and unfair repayments. Gender differences in brain activation were only observed during cooperative repayments, with males activating the TPJ more than females, and females activating the caudate more. The findings suggest relatively mature processes of trust and reciprocity in the investigated age range. Gender differences only occur in unfair contexts, becoming more pronounced with age. Largely similar neural activation in males and females and few age effects suggest that similar, mature cognitive strategies are employed. Copyright © 2017 The Authors. Published by Elsevier Ltd..

Our clinical experience showed that there has been no decrease in pediatric cases of acute viral hepatitis in Kathmandu. The objective of the study was to analyze the etiology, clinical features, laboratory parameters, sonological findings and other to determine the probable prognostic factors of Acute Viral Hepatitis in pediatric population. Consecutive patients of suspected Acute Viral Hepatitis, below the age of 15 years, attending the liver clinic between January 2006 and December 2010 were studied. After clinical examination they were subjected to blood tests and ultrasound examination of abdomen. The patients were divided in 3 age groups; 0-5, 5-10 and 5-15 years. Clinical features, laboratory parameters, ultrasound findings were compared in three age groups. Etiology of Acute Viral Hepatitis was Hepatitis A virus 266 (85%), Hepatitis E virus in 24 (8%), Hepatitis B virus in 15 (5%). In 7(2%) patients etiology was unknown. Three patients went to acute liver failure but improved with conservative treatment. There was no statistical difference in most of the parameters studied in different age groups. Ascites was more common in 5-10 years age group. Patients with secondary bacterial infection, ultrasound evidence of prominent biliary tree and ascites were associated with increased duration of illness. Patients with history of herbal medications had prolonged cholestasis. Hepatitis A is most common cause of Acute Viral Hepatitis in pediatric population. Improper use of herbal medications, secondary bacterial infection and faulty dietary intake was associated with prolonged illness. Patients with prominent biliary radicals should be treated with antibiotics even with normal blood counts for earlier recovery.

Nomograms to predict normal aortic root diameter for body surface area (BSA) in broad ranges of age have been widely used but are limited by lack of consideration of gender effects, jumps in upper limits of aortic diameter among age strata, and data from older teenagers. Sinus of Valsalva diameter was measured by American Society of Echocardiography convention in normal-weight, nonhypertensive, nondiabetic subjects ≥15 years old without aortic valve disease from clinical or population-based samples. Analyses of covariance and linear regression with assessment of residuals identified determinants and developed predictive models for normal aortic root diameter. In 1,207 apparently normal subjects ≥15 years old (54% women), aortic root diameter was 2.1 to 4.3 cm. Aortic root diameter was strongly related to BSA and height (r = 0.48 for the 2 comparisons), age (r = 0.36), and male gender (+2.7 mm adjusted for BSA and age, p <0.001 for all comparisons). Multivariable equations using age, gender, and BSA or height predicted aortic diameter strongly (R = 0.674 for the 2 comparisons, p <0.001) with minimal relation of residuals to age or body size: for BSA 2.423 + (age [years] × 0.009) + (BSA [square meters] × 0.461) - (gender [1 = man, 2 = woman] × 0.267), SEE 0.261 cm; for height 1.519 + (age [years] × 0.010) + (height [centimeters] × 0.010) - (gender [1 = man, 2 = woman] × 0.247), SEE 0.215 cm. In conclusion, aortic root diameter is larger in men and increases with body size and age. Regression models incorporating body size, age, and gender are applicable to adolescents and adults without limitations of previous nomograms. Copyright © 2012 Elsevier Inc. All rights reserved.

Rigidity in gender-typed behaviors in early childhood: a longitudinal study of ethnic minority children.

2013-01-01

A key prediction of cognitive theories of gender development concerns developmental trajectories in the relative strength or rigidity of gender typing. To examine these trajectories in early childhood, 229 children (African American, Mexican American, and Dominican American) were followed annually from age 3 to 5 years, and gender-stereotypical appearance, dress-up play, toy play, and sex segregation were examined. High gender-typing was found across ethnic groups, and most behaviors increased in rigidity, especially from age 3 to 4 years. In addressing controversy surrounding the stability and structure of gender-typing it was found that from year to year, most behaviors showed moderately stable individual differences. Behaviors were uncorrelated within age but showed more concordance in change across time, suggesting that aspects of gender-typing are multidimensional, but still show coherence. © 2013 The Authors.

Jen, Sarah

2017-01-01

Little research has explored the intersection of aging and sexuality. This qualitative study is informed by a life course approach and narrative gerontology methods. Semistructured interviews were conducted with 13 women age 55 and older to explore the effects of gender, aging, and living environment on past and current sexual experiences. Subthemes from each major theme are discussed, including: (a) messages about and perceived effects of gender, (b) perceived effects of aging, and (c) perceived effects of living environment. Findings support the use of dynamical systems theory to study women's sexual experiences.

Violent behaviour associated with alcohol consumption is frequently reported by different media. Clinical data analysing the correlation between alcohol intoxication, age, gender and violence are scarce. The aim of this study was to evaluate the influence of age, gender and blood alcohol content on violent behaviour under the influence of alcohol under central European conditions. Three hundred patients admitted to the emergency department were included into this study in the time period from January 01. to December 31. 2009. The inclusion criteria were a blood alcohol content (BAC) of ≥10 mmol/l, any traumatic injury and an age ≥16 years. Violence was defined as an evitable act committed by others leading to patient's hospitalisation. The data were compared with Wilcoxon and χ2-test for proportions. The data were considered as significant if p<0,05. Predictive quality was evaluated by using receiver operating characteristic (ROC) curve. Independent predictors were analyzed by logistic regression analysis. The average age was 36,9±16,9 years (range: 16-84 years), 259 (86%) males and 41 (24%) females. There was a significant difference in gender (odds ratio for gender male 2,88; CI 95%: 1,24-6,67; p<0,001) and age dependent (odds ratio for each year of age 0,94; CI 95%: 0,93-0,96; p<0,0001) violence with no correlation to blood alcohol content found. Logistic regression analysis revealed male gender and young age as an independent predictor for violence. These results clarify the relationship between alcohol, age, gender and violence and have important implications for municipal-level alcohol policies.

The Student-Teacher Relationship Scale (STRS) is widely used to examine teachers' relationships with young students in terms of closeness, conflict, and dependency. This study aimed to verify the dimensional structure of the STRS with confirmatory factor analysis, test its measurement invariance across child gender and age, improve its measurement of the dependency construct, and extend its age range. Teachers completed a slightly adapted STRS for a Dutch sample of 2335 children aged 3 to 12. Overall, the 3-factor model showed an acceptable fit. Results indicated metric invariance across gender and age up to 8years. Scalar invariance generally did not hold. Lack of metric invariance at ages 8 to 12 primarily involved Conflict items, whereas scale differences across gender and age primarily involved Closeness items. The adapted Dependency scale showed strong invariance and higher internal consistencies than the original scale for this Dutch sample. Importantly, the revealed non-invariance for gender and age did not influence mean group comparisons. Copyright © 2011 Society for the Study of School Psychology. Published by Elsevier Ltd.

An accurate projection for ambulance demand is essential to enable better resource planning for the future that strives to either maintain current levels of services or reconsider future standards and expectations. More than 2 million cases of emergency room attendance in 2008 were obtained from the Hong Kong Hospital Authority to project the demand for its ambulance services in 2036. The projection of ambulance demand in 2036 was computed in consideration of changes in the age-gender structure between 2008 and 2036. The quadratic relation between average daily temperature and daily ambulance demand in 2036 was further explored by including and excluding age-gender demographic changes. Without accounting for changes in the age-gender structure, the 2036 ambulance demand for age groups of 65 and above were consistently underestimated (by 38%-65%), whereas those of younger age groups were overestimated (by 6%-37%). Moreover, changes in the 2008 to 2036 age-gender structure also shift upward and emphasize relationships between average daily temperature and daily ambulance demand at both ends of the quadratic U-shaped curve. Our study reveals a potential societal implication of ageing population on the demand for ambulance services. © 2012 APJPH.

Ferritin reference values vary by age, gender, and ethnicity. We aimed to determine reference values of serum ferritin (SF) and the percentage of transferrin saturation (TSAT) for Korean children and adolescents. We analyzed data from 2,487 participants (1,311 males and 1,176 females) aged 10-20 years from the Korea National Health and Nutrition Examination Survey (2010-2012). We calculated age- and gender-stratified means and percentile values for SF and TSAT. We first plotted mean SF and TSAT by gender and according to age. In males, mean SF tended to be relatively constant among participants aged 10 to 14 years, with an upward trend thereafter. Mean SF trended downward among female participants until the age of 15 years and remained constant thereafter. Thus, significant gender differences in ferritin exist from the age of 14 years. High levels of SF were associated with obesity, and lower SF levels were associated with anemia and menarche status. We established reference values of SF and TSAT according to age and gender. The reference values for SF calculated in this study can be used to test the association between SF values and other defined diseases in Korean children and adolescents.

Androgen insensitivity syndrome (AIS) is the most frequent etiology of 46,XY disorders of sex development (DSDs), and it is an X-linked disorder caused by mutations in the androgen receptor (AR) gene. AIS patients present a broad phenotypic spectrum and individuals with a partial phenotype present with different degrees of undervirilized external genitalia. There are more than 500 different AR gene allelic variants reported to be linked to AIS, but the presence of somatic mosaicisms has been rarely identified. In the presence of a wild-type AR gene, a significant degree of spontaneous virilization at puberty can be observed, and it could influence the gender assignment, genetic counseling and the clinical and psychological management of these patients and the psychosexual outcomes of these patients are not known. In this study, we report two patients with AR allelic variants in heterozygous (c.382G>T and c.1769-1G>C) causing a partial AIS (PAIS) phenotype. The first patient was raised as female and she had undergone a gonadectomy at puberty. In both patients there was congruency between gender of rearing and gender identity and gender role. Somatic mosaicism is rare in AIS and nonsense AR variant allelic can cause partial AIS phenotype in this situation. Despite the risk of virilization and prenatal androgen exposure, the gender identity and gender role was concordant with sex of rearing in both cases. A better testosterone response can be expected in male individuals and this should be considered in the clinical management.

Biological aspects of gender disorders.

The scientific community is very interested in the biological aspects of gender disorders and sexual orientation. There are different levels to define an individual's sex: chromosomal, gonadic, and phenotypic sex. Concerning the psychological sex, men and women are different by virtue of their own gender identity, which means they recognize themselves as belonging to a determinate sex. They are different also as a result of their own role identity, a set of behaviors, tendencies, and cognitive and emotional attitudes, commonly defined as "male" and "female". Transsexuality is a disorder characterized by the development of a gender identity opposed to phenotypic sex, whereas homosexuality is not a disturbance of gender identity but only of sexual attraction, expressing sexual orientation towards people of the same sex. We started from a critical review of literature on genetic and hormonal mechanisms involved in sexual differentiation. We re-examined the neuro-anatomic and functional differences between men and women, with special reference to their role in psychosexual differentiation and to their possible implication in the genesis of homosexuality and identity gender disorders. Homosexuality and transsexuality are conditions without a well defined etiology. Although the influence of educational and environmental factors in humans is undeniable, it seems that organic neurohormonal prenatal and postnatal factors might contribute in a determinant way in the development of these two conditions. This "organicistic neurohormal theory" might find support in the study of particular situations in which the human fetus is exposed to an abnormal hormonal environment in utero.

This study examines and explains the gender disparity in health despite rapid modernization in South Korea where the social structure is still based on traditional gender relations. A nationally representative sample of 2897 men and 3286 women aged 25-64 from the 2001 Korean National Health and Nutrition Examination Survey was analyzed. Health indicators included self rated health and chronic disease. Age-adjusted prevalence was computed according to a gender and odds ratios (OR) derived from logistic regression. Percentage changes in OR by inclusion of determinant variables (socio-structural, psychosocial, and behavioral) into the base logistic regression model were used to estimate the contributions to the gender gap in two morbidity measures. Results showed a substantial female excess in ill-health in both measures, revealing an increasing disparity in the older age group. Group-specific age-adjusted prevalence of ill-health showed an inverse relationship to socioeconomic position. When adjusting for each determinant, employment status, education, and depression contributed the greatest to the gender gap. After adjusting for all suggested determinants, 78% for self rated health and 86% for chronic disease in excess OR could be explained. After stratifying for age, the full model provided a complete explanation for the female excess in chronic illness, but for self rated health a female excess was still evident for the younger age group. Socio-structural factors played a crucial role in accounting for female excess in ill-health. This result calls for greater attention to gender-based health inequality stemming from socio-structural determinants in South Korea. Cross-cultural validation studies are suggested for further discussion of the link between changing gender relations and the gender health gap in morbidity in diverse settings.

The weight of the placenta is a crude but useful proxy for its function in vivo. Accordingly extremes of placental weight are associated with adverse pregnancy outcomes while even normal variations in placental size may impact lifelong health. Centile charts of placental weight for gestational age and gender are used to identify placental weight extremes but none report the effect of parity. Thus the objective was to produce gender and gestational age specific centile charts for placental weight in nulliparous and multiparous women. Data was extracted from the Aberdeen Maternity and Neonatal Databank for all women delivering singleton babies in Aberdeen city and district after 24 weeks gestation. Gestational age specific centile charts for placental weight by gender and parity grouping (n = 88,649 deliveries over a 30 year period) were constructed using the LMS method after exclusion of outliers (0.63% of deliveries meeting study inclusion criteria). Tables and figures are presented for placental weight centiles according to gestational age, gender and parity grouping. Tables are additionally presented for the birth weight to placental weight ratio by gender. Placental weight and the fetal:placental weight ratio were higher in male versus female deliveries. Placental weight was greater in multiparous compared with nulliparous women. We present strong evidence that both gender and parity grouping influence placental weight centiles. The differences at any given gestational age are small and the effects of parity are greater overall than those of gender. In contrast the birth weight to placental weight ratio differs by gender only. These UK population specific centile charts may be useful in studies investigating the role of the placenta in mediating pregnancy outcome and lifelong health. Copyright © 2012 Elsevier Ltd.

This study examined the effects of age and gender on wideband energy absorbance in adults with normal middle ear function. Forty young adults (14 men, 26 women, aged 20-38 years), 31 middle-aged adults (16 men, 15 women, aged 42-64 years), and 30 older adults (20 men, 10 women, aged 65-82 years) were assessed. Energy absorbance (EA) data were collected at 30 frequencies using a prototype commercial instrument developed by Interacoustics. Results showed that the young adult group had significantly lower EA (between 400 and 560 Hz) than the middle-aged group. However, the middle-aged group showed significantly lower EA (between 2240 and 5040 Hz) than the young adult group. In addition, the older adult group had significantly lower EA than the young adult group (between 2520 and 5040 Hz). No significant difference in EA was found at any frequency between middle-aged and older adults. Across age groups, gender differences were found with men having significantly higher EA values than women at lower frequencies, whereas women had significantly higher EA at higher frequencies. This study provides evidence of the influence of gender and age on EA in adults with normal outer and middle ear function. These findings support the importance of establishing age- and gender-specific EA norms for the adult population.

Several aspects of thyroid dysfunction have not been fully characterized in large series of male patients. Our aim was to investigate the etiology and clinical features of hypothyroidism and assess the adequacy of replacement therapy in men attending an endocrinology clinic. We studied a group of 260 men (mean (+/-standard deviation) age 58.3 +/- 16.1 years) periodically seen because of thyroid hypofunction. We evaluated the etiology of hypothyroidism, presence or absence of goiter, time of evolution from diagnosis, current thyroid autoimmunity and thyroid functional status, and adequacy of disease control. Overt hypothyroidism was found in 182 (70.0%) and subclinical hypothyroidism in 78 (30.0%) patients. Autoimmune thyroiditis was the most frequent etiology (n = 107, 41.2%). Of these, 96 (89.7%) showed no goiter. Thyroid peroxidase antibodies were measured in 238 patients, being positive in 129 (54.2%) and negative in 109 (45.8%) patients. After excluding patients with thyroid carcinoma and those with recently diagnosed hypothyroidism, we found an adequate control of thyroid function, ie, normal thyrotropin and free thyroxine levels, in 95 patients (64.2%). Adequacy of treatment did not show any relationship with age, age at diagnosis, etiology, and autoimmune status. However, adequacy was significantly related to the degree of thyroid hypofunction (P < 0.001) and to the duration of disease (P < 0.01). We conclude that autoimmune thyroiditis, mainly the nongoitrous form, and postoperative hypothyroidism are the foremost causes of thyroid hypofunction in male patients. Adequacy of replacement treatment seems to be mainly related to the degree of thyroid hypofunction and the time from starting therapy.

Abstract Purpose: Gender-affirming surgeries and hormone therapy are medically necessary treatments to alleviate gender dysphoria; however, significant gaps exist in the research and clinical literature on surgery utilization and age of hormone therapy initiation among transgender adults. Methods: We conducted a retrospective review of electronic health record data from a random sample of 201 transgender patients of ages 18–64 years who presented for primary care between July 1, 2010 and June 30, 2015 (inclusive) at an urban community health center in Boston, MA. Fifty percent in our analyses were trans masculine (TM), 50% trans feminine, and 24% reported a genderqueer/nonbinary gender identity. Regression models were fit to assess demographic, gender identity-related, sexual history, and mental health correlates of gender-affirming surgery and of age of hormone therapy initiation. Results: Overall, 95% of patients were prescribed hormones by their primary care provider, and the mean age of initiation of masculinizing or feminizing hormone prescriptions was 31.8 years (SD=11.1). Younger age of initiation of hormone prescriptions was associated with being TM, being a student, identifying as straight/heterosexual, having casual sexual partners, and not having past alcohol use disorder. Approximately one-third (32%) had a documented history of gender-affirming surgery. Factors associated with increased odds of surgery were older age, higher income levels, not identifying as bisexual, and not having a current psychotherapist. Conclusion: This study extends our understanding of prevalence and factors associated with gender-affirming treatments among transgender adults seeking primary care. Findings can inform future interventions to expand delivery of clinical care for transgender patients. PMID:29159310

Social categories guide young children's preferences for novel objects

To whom do children look when deciding on their own preferences? To address this question, three-year-old children were asked to choose between objects or activities that were endorsed by unfamiliar people who differed in gender, race (White, Black), or age (child, adult). In Experiment 1, children demonstrated robust preferences for objects and activities endorsed by children of their own gender, but less consistent preferences for objects and activities endorsed by children of their own race. In Experiment 2, children selected objects and activities favored by people of their own gender and age. In neither study did most children acknowledge the influence of these social categories. These findings suggest that gender and age categories are encoded spontaneously and influence children's preferences and choices. For young children, gender and age may be more powerful guides to preferences than race. PMID:20590724

Although mitral regurgitation (MR) is a well-recognized prognosis factor, its true prevalence is probably underestimated and its etiology and mechanisms have not been sufficiently explored. The study aim was to evaluate the burden of MR, focusing attention on its frequency, severity, etiology, mechanism, and other associated conditions. Between February and June 2015, a total of 39,855 consecutive echocardiographic studies was performed at nine tertiary hospitals, and were prospectively included in the study. MR severity was graded into four groups, ranging from none or trace to severe MR, in accordance with the recommendations of the European Association of Cardiovascular Imaging. Patients with moderate to severe MR were selected for the analysis. MR was detected in 22.6% of cases. MR severity was mild in 82.5% of patients (n = 7,376), moderate in 11.7% (n = 1,048), and severe in 5.8% (n = 521). Concomitant valvular heart disease was present in 3,544 patients (39.7%), with tricuspid regurgitation the most frequently encountered (21.6%). Among moderate and severe MR, primary MR was more frequent than secondary MR (58.8% versus 23.5%), with degenerative valve disease being the most common cause of primary MR (49.2%). A third group composed of mixed forms of MR was described in 17.8% of cases. MR is a common finding on echocardiography, and is frequently associated with other valvular heart disease. Most MRs are of degenerative origin. The primary and secondary forms of MR differ significantly in their clinical presentation with regard to gender, age, and ventricular function. There appears to be a gap for a 'mixed' group, though further studies are needed to confirm this suggestion.

The focus of care in disorders of sex development (DSD) is often directed to issues related to sex and gender development. In addition, the molecular etiology remains unclear in the majority of cases. To report the range of associated conditions identified in the international DSD (I-DSD) Registry. Anonymized data were extracted from the I-DSD Registry for diagnosis, karyotype, sex of rearing, genetic investigations, and associated anomalies. If necessary, clarification was sought from the reporting clinician. Of 649 accessible cases, associated conditions occurred in 168 (26%); 103 (61%) cases had one condition, 31 (18%) had two conditions, 20 (12%) had three conditions, and 14 (8%) had four or more conditions. Karyotypes with most frequently reported associations included 45,X with 6 of 8 affected cases (75%), 45,X/46,XY with 19 of 42 cases (45%), 46,XY with 112 of 460 cases (24%), and 46,XX with 27 of 121 cases (22%). In the 112 cases of 46,XY DSD, the commonest conditions included small for gestational age in 26 (23%), cardiac anomalies in 22 (20%), and central nervous system disorders in 22 (20%), whereas in the 27 cases of 46,XX DSD, skeletal and renal anomalies were commonest at 12 (44%) and 8 (30%), respectively. Of 170 cases of suspected androgen insensitivity syndrome, 19 (11%) had reported anomalies and 9 of these had confirmed androgen receptor mutations. Over a quarter of the cases in the I-DSD Registry have an additional condition. These associations can direct investigators toward novel genetic etiology and also highlight the need for more holistic care of the affected person.

Over the years, Uganda has been one of the low and middle-income countries bearing the heaviest burden of road traffic incidents (RTI). Since the proclamation of the United Nations Decade of Action for Road Safety 2011 - 2020, a number of measures have been taken to reduce the burden. However, they ought to be premised on existing evidence-based research; therefore, the present review ventures to report the most recent five-year trend of RTI in Uganda. Based on Preferred Reporting Items for Systematic Reviews and Meta-Data Analysis (PRISMA) guidelines, a systematic review was employed. Using a thematic analysis, the articles were grouped into: trauma etiology, trauma care, mortality, cost, trauma registry and communication, intervention and treatment for final analysis. Of the nineteen articles that were identified to be relevant to the study, the etiology of RTI was inevitably observed to be an important cause of injuries in Uganda. The risk factors cut across: the crash type, injury physiology, cause, victims, setting, age, economic status, and gender. All studies that were reviewed have advanced varying recommendations aimed at responding to the trend of RTIs in Uganda, of which some are in tandem with the five pillars of the United Nations Decade of Action for Road Safety 2011 - 2020. Peripheral measures of the burden of RTIs in Uganda were undertaken within afive-year timeframe (2011-2015) of implementing the United Nations Decade of Action for Road Safety. The measures however, ought to be scaled-up on robust evidence based research available from all the concerned stakeholders beyond Kampala or central region to other parts of Uganda. © 2017 KUMS, All rights reserved.

The role of melatonin in the neurodevelopmental etiology of schizophrenia: A study in human olfactory neuronal precursors.

Dim light exposure of the mother during pregnancy has been proposed as one of the environmental factors that affect the fetal brain development in schizophrenia. Melatonin circulating levels are regulated by the environmental light/dark cycle. This hormone stimulates neuronal differentiation in the adult brain. However, little is known about its role in the fetal human brain development. Olfactory neuronal precursors (ONPs) are useful for studying the physiopathology of neuropsychiatric diseases because they mimic all the stages of neurodevelopment in culture. Here, we first characterized whether melatonin stimulates neuronal differentiation in cloned ONPs obtained from a healthy control subject (HCS). Then, melatonin effects were evaluated in primary cultures of ONPs derived from a patient diagnosed with schizophrenia (SZ) and an age- and gender-matched HCS. Axonal formation was evidenced morphologically by tau immunostaining and by GSK3β phosphorylated state. Potassium-evoked secretion was assessed as a functional feature of differentiated neurons. As well, we report the expression of MT1/2 receptors in human ONPs for the first time. Melatonin stimulated axonal formation and ramification in cloned ONPs through a receptor-mediated mechanism and enhanced the amount and velocity of axonal and somatic secretion. SZ ONPs displayed reduced axogenesis associated with lower levels of pGSK3β and less expression of melatonergic receptors regarding the HCS ONPs. Melatonin counteracted this reduction in SZ cells. Altogether, our results show that melatonin signaling is crucial for functional differentiation of human ONPs, strongly suggesting that a deficit of this indoleamine may lead to an impaired neurodevelopment which has been associated with the etiology of schizophrenia. © 2017 John Wiley & Sons A/S.

Autism spectrum disorder (ASD) is a neurological disorder that presents a spectrum of qualitative impairments in social interaction, communication, as well as restricted and stereotyped behavioral patterns, interests, and activities. Several studies have suggested that the etiology of ASD can be partly explained by oxidative stress. However, the implications of abnormal transsulfuration metabolism and oxidative stress, and their relation with ASD are still unclear. The purpose of this study was to evaluate several transsulfuration pathway metabolites in Chinese participants diagnosed with ASD, to better understand their role in the etiology of this disorder. Fifty children (39 male, 11 female) diagnosed with ASD and 50 age- and gender-matched non-ASD children (i.e., control group) were included in this study. This prospective blinded study was undertaken to assess transsulfuration and oxidative metabolites, including levels of homocysteine (Hcy), cysteine (Cys), total glutathione (tGSH), reduced glutathione (GSH), oxidized glutathione (GSSG), and glutathione ratio (GSH/GSSG). The clinical severity of ASD was evaluated with the Childhood Autism Rating Scale (CARS), and the autistic children's present behavior was measured by the Autism Behavior Checklist (ABC). The results indicated that Hcy and GSSG levels were significantly higher in children diagnosed with ASD, Cys, tGSH and GSH levels as well as the GSH/GSSG ratio showed remarkably lower values in ASD children compared to control subjects. Hcy levels correlated significantly with increasing CARS scores and GSSG levels in children with ASD. Our results suggest that an abnormal transsulfuration metabolism and reduced antioxidant capacity (i.e., hyperhomocysteinemia and increased oxidative stress), and Hcy level appears to have a potentially negative impact on clinical severity of autistic disorder.

To assess the evidence for diagnostic tests and therapies for transverse myelitis (TM) and make evidence-based recommendations. A review of the published literature from 1966 to March 2009 was performed, with evidence-based classification of relevant articles. Level B recommendations: neuromyelitis optica (NMO)-immunoglobulin G (IgG) antibodies should be considered useful to determine TM cause in patients presenting with clinical acute complete transverse myelitis (ACTM) features. The presence of NMO-IgG antibodies (aquaporin-4-specific antibodies) should be considered useful in determining increased TM recurrence risk. Level C recommendations: in suspected TM, distinction between ACTM or acute partial transverse myelitis may be considered useful to determine TM etiology and risk for relapse (more common with APTM). Age and gender may be considered useful to determine etiology in patients presenting with TM syndrome, with spinal infarcts seen more often in older patients and more female than male patients having TM due to multiple sclerosis (MS). Brain MRI characteristics consistent with those of MS may be considered useful to predict conversion to MS after a first partial TM episode. Longer spinal lesions extending over >3 vertebral segments may be considered useful in determining NMO vs MS. CSF examination for cells and oligoclonal bands may be considered useful to determine the cause of the TM syndrome. Plasma exchange may be considered in patients with TM who fail to improve after corticosteroid treatment. Rituximab may be considered in patients with TM due to NMO to decrease the number of relapses. Level U recommendations: there is insufficient evidence to support or refute the efficacy of other TM therapies or the usefulness of ethnicity to determine the cause of a subacute myelopathy.

We hypothesized that patients currently diagnosed with cryptogenic cirrhosis (CC) have truly 'cryptogenic' liver disease, which is unlikely to have evolved from NASH. The aim of this study is to characterize patients with CC, and compare their characteristics to patients with cirrhosis of other etiologies. To investigate this, we compared the clinical characteristics of adults with CC (n = 7,999) to those with cirrhosis caused by non-alcoholic steatohepatitis (NASH) (n = 11,302), alcohol (n = 21,714) and autoimmune hepatitis (n = 3,447), using the UNOS database from 2002-16. We performed an age, gender and year of listing matched comparison of CC and NASH (n = 7,201 in each group), and also stratified patients by the presence of obesity or diabetes mellitus (DM). From 2002 to 2016, patients listed with a diagnosis of NASH increased from about 1% to 16% while CC decreased from 8% to 4%. A logistic regression model using the entire United Network for Organ Sharing data (n = 138,021) suggested that the strongest predictors of NASH were type 2 DM, obesity, age ≥60 years, female gender and white race. Type 2 DM was more common in patients with NASH (53%) than those with CC (29%), alcoholic cirrhosis (16%) and autoimmune hepatitis (16%), and obesity was more common in NASH (65.3%) compared to the other three groups (33-42%). There were more white individuals (82.3%) in the NASH group and a lower prevalence of black, Hispanic and Asian individuals, compared to the other three groups. Hepatocellular carcinoma was more commonly seen in NASH (19% vs. 9-13% in the other groups) and this is not influenced by obesity and type 2 DM. The differences between CC and NASH remained unchanged even when two groups were matched for age, gender and year of listing, or when stratified by the presence or absence of obesity or type 2DM. Based on risk perspectives, CC should not be equated with the term 'NASH cirrhosis'. We hypothesized that cryptogenic cirrhosis is a distinct condition from cirrhosis caused by non-alcoholic steatohepatitis (NASH). By comparing cryptogenic cirrhosis with cirrhosis of other causes, we found clear clinical differences. Therefore, cryptogenic cirrhosis should not be considered the same as NASH cirrhosis. Further investigations are required to identify unknown causes of cirrhosis. Copyright © 2017 European Association for the Study of the Liver. Published by Elsevier B.V. All rights reserved.

The present study examined the influence of maternal and child characteristics on parenting behaviors in a genetically informative study. The participants were 976 twins and their mothers from the Colorado Longitudinal Twin Study and the Twin Infant Project. Indicators of positive parenting were coded during parent-child interactions when twins were 7-36 months old. Child cognitive abilities and affection were independent correlates of positive parenting. There were significant gender differences in the magnitude of genetic and environmental influences on positive parenting, with shared environmental influences on parenting of girls and additive genetic influences on parenting of boys. Girls received significantly more positive parenting than boys. Differences in etiology of positive parenting may be explained by developmental gender differences in child cognitive abilities and affection, such that girls may have more rewarding interactions with parents, evoking more positive parenting.

The present study examined the dose-dependent (0.25-5 mg/kg) effects of systemic naloxone upon deprivation-induced intake and high-fat intake as functions of age (4, 8, 14, and 20 months), gender, and gonadectomy in rats. Significant increases in body weight were observed as functions of age and gonadectomy. Whereas aging significantly reduced basal deprivation-induced intake, it generally failed to alter basal high-fat intake. Whereas age, gender, and gonadectomy failed to alter the decreases in deprivation-induced intake following low (0.25-2.5 mg/kg) naloxone doses, sham males displayed significantly greater age-related and gender-related inhibition following the 5 mg/kg dose of naloxone. Young gonadectomized rats displayed significant increases in naloxone's inhibition of deprivation-induced intake as well. More dramatic changes occurred in naloxone's inhibition of high-fat intake. Naloxone's potency increased in sham female rats as a function of age, and decreased in sham males and ovariectomized females as a function of age. Whereas sham males and ovariectomized females were most sensitive to naloxone's inhibition of high-fat intake at young ages, sham females were most sensitive at older ages. These data indicate that effects of age, gender, and gonadectomy upon naloxone-induced hypophagia dissociate as a function of the type of intake. Because selective opioid antagonist studies demonstrate that deprivation-induced intake is mediated by the mu1 receptor and high-fat intake is mediated by kappa and mu2 receptors, it is postulated that the differential effects of aging, gender, and gonadectomy variables upon opioid mediation of the two forms of intake may reflect their interaction with different opioid receptor subtypes.

We report the bone attenuation of ankle joint measured on computed tomography (CT) and the cause of injury in patients with ankle fractures. The results showed age- and gender-dependent low bone attenuation and low-energy trauma in elderly females, which suggest the osteoporotic features of ankle fractures. This study was performed to investigate the osteoporotic features of ankle fracture in terms of bone attenuation and cause of injury. One hundred ninety-four patients (mean age 51.0 years, standard deviation 15.8 years; 98 males and 96 females) with ankle fracture were included. All patients underwent CT examination, and causes of injury (high/low-energy trauma) were recorded. Mean bone attenuations of the talus, medial malleolus, lateral malleolus, and distal tibial metaphysis were measured on CT images. Patients were divided into younger age (<50 years) and older age (≥50 years) groups, and mean bone attenuation and causes of injury were compared between the two groups in each gender. Proportion of low-energy trauma was higher in the older age group than in the younger age group, but the difference was only significant in female gender (p = 0.011). The older age group showed significantly lower bone attenuation in the talus, medial malleolus, lateral malleolus, and distal tibial metaphysis than the younger age group in both genders. The older age group showed more complex pattern of fractures than the younger age group. With increasing age, bone attenuations tended to decrease and the difference of bone attenuation between the genders tended to increase in the talus, medial malleolus, lateral malleolus, and distal tibial metaphysis. Ankle fracture had features of osteoporotic fracture that is characterized by age- and gender-dependent low bone attenuation. Ankle fracture should not be excluded from the clinical and research interest as well as from the benefit of osteoporosis management.

Dementia is increasingly prevalent due to rapid aging of the population, but under-recognized among people with low education levels. This is partly due to a lack of appropriate and precise normative data, which underestimates cognitive aging in the use of screening tools for dementia. We aimed to improve the precision of screening for cognitive impairment, by characterizing the patterns of cognitive aging and derived normative data of the Mini-Mental State Examination (MMSE) for illiterate and low-educated populations. This community-based study included data from 2,280 individuals aged 40 years or older from two rural areas. Multiple linear modeling examined the effect of aging on cognition reflected by the MMSE, stratified by education level and gender. Threshold effect of age on cognition was performed using a smoothing function. The majority of participants (60.4%) were illiterate or had attended only primary school (24.6%). The effect of aging on cognition varied by gender and education. Primary-school educated females and males remained cognitively stable up to 62 and 71 years of age, respectively, with MMSE score declining 0.4 and 0.8 points/year in females and males thereafter. Illiterates females scored 2.3 points lower than illiterate males, and scores for both declined 0.2 points/year. According to these results, normative data stratified by age, education and gender was generated. This study suggests gender and educational differences exist in cognitive aging among adults with limited or no formal education. To improve screening precision for cognitive impairment with the use of MMSE in low-educated population, age, gender, and education level should be considered.

Background Anthropometry is a necessary aspect of aging-related research, especially in biomechanics and injury prevention. Little information is available on inertial parameters in the geriatric population that account for gender and obesity effects. The goal of this study was to report body segment parameters in adults aged 65 years and older, and to investigate the impact of aging, gender and obesity. Methods Eighty-three healthy old (65–75 yrs) and elderly (>75 yrs) adults were recruited to represent a range of body types. Participants underwent a whole body dual energy x-ray absorptiometry scan. Analysis was limited to segment mass, length, longitudinal center of mass position, and frontal plane radius of gyration. A mixed-linear regression model was performed using gender, obesity, age group and two-way and three-way interactions (α=0.05). Findings Mass distribution varied with obesity and gender. Males had greater trunk and upper extremity mass while females had a higher lower extremity mass. In general, obese elderly adults had significantly greater trunk segment mass with less thigh and shank segment mass than all others. Gender and obesity effects were found in center of mass and radius of gyration. Non-obese individuals possessed a more distal thigh and shank center of mass than obese. Interestingly, females had more distal trunk center of mass than males. Interpretation Age, obesity and gender have a significant impact on segment mass, center of mass and radius of gyration in old and elderly adults. This study underlines the need to consider age, obesity and gender when utilizing anthropometric data sets. PMID:20005028

Association between psychosomatic health symptoms and common mental illness in Ghanaian adolescents: Age and gender as potential moderators.

Little is known about the role of age and gender in the association between psychosomatic symptoms and common mental illness in Ghanaian adolescents. This cross-sectional study examined age and gender as moderators between psychosomatic symptoms and common mental illness using data from a school-based survey ( N = 770). Males reported higher psychosomatic symptoms and common mental illness, while younger adolescents reported higher common mental illness only. Psychosomatic symptoms were positively associated with common mental illness, but age and gender did not moderate this association. Interventions aimed at reducing the prevalence rate in psychosomatic symptoms are crucial in decreasing common mental illness in Ghanaian adolescents.

To establish age and gender specific reference values for incidental coronary artery and thoracic aorta calcification scores on routine diagnostic CT scans. These reference values can aid in structured reporting and interpretation of readily available imaging data by chest CT readers in routine practice. A random sample of 1572 (57% male, median age 61 years) was taken from a study population of 12,063 subjects who underwent diagnostic chest CT for non-cardiovascular indications between January 2002 and December 2005. Coronary artery and thoracic aorta calcifications were graded using a validated ordinal score. The 25th, 50th and 75th percentile cut points were calculated for the coronary artery and thoracic aorta calcification scores within each age/gender stratum. The 75th percentile cut points for coronary artery calcification scores were higher for men than for women across all age groups, with the exception of the lowest age group. The 75th percentile cut points for thoracic aorta calcifications scores were comparable for both genders across all age groups. Based on the obtained age and gender reference values a calculation tool is provided, that allows one to enter an individual's age, gender and calcification scores to obtain the corresponding estimated percentiles. The calculation tool as provided in this study can be used in daily practice by CT readers to examine whether a subject has high calcifications scores relative to others with the same age and gender.

Exposure to community violence through witnessing or being directly victimized has been associated with conduct problems in a range of studies. However, the relationship between community violence exposure (CVE) and conduct problems has never been studied separately in healthy individuals and individuals with conduct disorder (CD). Therefore, it is not clear whether the association between CVE and conduct problems is due to confounding factors, because those with high conduct problems also tend to live in more violent neighborhoods, i.e., an ecological fallacy. Hence, the aim of the present study was: (1) to investigate whether the association between recent CVE and current conduct problems holds true for healthy controls as well as adolescents with a diagnosis of CD; (2) to examine whether the association is stable in both groups when including effects of aggression subtypes (proactive/reactive aggression), age, gender, site and socioeconomic status (SES); and (3) to test whether proactive or reactive aggression mediate the link between CVE and conduct problems. Data from 1178 children and adolescents (62% female; 44% CD) aged between 9 years and 18 years from seven European countries were analyzed. Conduct problems were assessed using the Kiddie-Schedule of Affective Disorders and Schizophrenia diagnostic interview. Information about CVE and aggression subtypes was obtained using self-report questionnaires (Social and Health Assessment and Reactive-Proactive aggression Questionnaire (RPQ), respectively). The association between witnessing community violence and conduct problems was significant in both groups (adolescents with CD and healthy controls). The association was also stable after examining the mediating effects of aggression subtypes while including moderating effects of age, gender and SES and controlling for effects of site in both groups. There were no clear differences between the groups in the strength of the association between witnessing violence and conduct problems. However, we found evidence for a ceiling effect, i.e., individuals with very high levels of conduct problems could not show a further increase if exposed to CVE and vice versa. Results indicate that there was no evidence for an ecological fallacy being the primary cause of the association, i.e., CVE must be considered a valid risk factor in the etiology of CD.

Individuals with an evening chronotype are at increased risk of experiencing emotional problems, including depressive symptoms. However, the mechanisms underlying these associations remain unclear. The present study aimed to determine whether poor sleep quality, substance use and cognitive emotion regulation difficulties - which have been implicated in the etiology of depression - mediate the relationship between chronotype and depressive symptoms in a student sample, which was assessed cross-sectionally and after 1 year. A total of 742 Dutch students (75% women, mean age 21.4 ± 2.9 years) completed the Quick Inventory of Depressive Symptomatology, the Morningness-Eveningness Questionnaire, the Pittsburgh Sleep Quality Index, a questionnaire assessing alcohol, caffeine, tobacco and cannabis use, the Cognitive Emotion Regulation Questionnaire and the Behavioral Inhibition/Activation Scale. A subsample (n = 115) was assessed 1 year later with the same questionnaires. Cross-sectional analyses showed that evening chronotype was associated with more depressive symptoms, adjusted for age and gender (β = -0.082, p = 0.028). The relationship between eveningness and depressive symptoms was mediated by sleep quality, alcohol consumption and the cognitive emotion regulation strategies of self-blame and positive reappraisal. In longitudinal analyses, eveningness at baseline predicted more depressive symptoms at follow-up, adjusted for age and gender (β = -0.29, p = 0.002); after additional adjustment for baseline depressive symptoms, chronotype remained a significant predictor of depressive symptoms at T2 (β = -0.16, t = -2.01, p = 0.047). Only poor sleep quality at follow-up was a significant mediator of this relationship. Even though the effect is small in terms of explained variance, eveningness is related to depressive symptoms and this relationship is mediated by poor sleep quality, also in a prospective design. Self-blame and reduced positive reappraisal are correlated with eveningness. Further research is needed to assess the efficacy of chronotherapeutic interventions for the prevention of depression, in addition to sleep education and cognitive approaches.

The human finger plays an extremely important role in tactile perception, but little is known about how age and gender affect its biophysical properties and their role in tactile perception. We combined studies on contact characteristics, mechanical properties and surface topography to understand age and gender effects on the human finger. The values obtained regarding contact characteristics (i.e. adhesive force) were significantly higher for women than for men. As for mechanical properties (i.e. Young's modulus E), a significant and positive correlation with age was observed and found to be higher for women. A positive correlation was observed between age and the arithmetic mean of surface roughness for men. However, an inverse age effect was highlighted for women. The age and gender effects obtained have never been reported previously in the literature. These results open new perspectives for understanding the weakening of tactile perception across ages and how it differs between men and women. PMID:28878982

Peripheral arterial disease (PAD) encompasses disease of all arteries of the body except the coronary arteries. The main etiology whatever the patient's age is atherosclerosis. Different etiologies can induce PAD especially when patients are younger than 50 years old and have no cardiovascular risk factors (smoking, hypertension, diabetes…). PAD that appears before 50 years old can be named juvenile PAD (JPAD) although there is no consensus about the definition. The aim of this work is to present the different etiologies of JPAD according to their hereditary, acquired or mixed origins. The following hereditary causes are addressed: Marfan syndrome, Ehlers-Danlos syndrome, homocystinuria, pseudoxanthoma elasticum, osteogenesis imperfecta "mid-aortic" syndrome. Among the acquired etiologies, inflammatory JPADs without extravascular signs such as atherosclerosis and Buerger's disease, inflammatory JPADs with extravascular signs as Takayasu's disease, Behçet's disease and Cogan's syndrome, JPADs like aortitis, embolic JPADs, iatrogenic JPADs, and mechanical or traumatic JPADs are described. Finally, mixed origins as thrombotic disease and fibromuscular dysplasia are presented. This work will assist clinicians in the diagnosis of JPAD. Copyright © 2016 Elsevier Masson SAS.
