The aim of this study was to determine factors affecting overall mortality in patients over 60 years of age who underwent surgery for gastric cancer in our clinic. Data on histopathological diagnosis (tumor size, lymph node status, and number), pathological stage, serum albumin level, tumor markers, complete blood count, and demographic information of 109 patients over 60 years of age who had surgery for gastric cancer between January 2011 and July 2016 were obtained retrospectively from the patient files. In addition, the survival status of all patients were examined and recorded. Metastatic lymph node ratio (MLR), red cell distribution width platelet ratio (RPR), neutrophil-lymphocyte ratio (NLR), plateletlymphocyte ratio (PLR), and prognostic nutritional index (PNI) were calculated. On univariate analysis of independent parameters, pathological LN number (p = 0.001), MLR (p <0.001), T3 (p = 0.001) or T4 (p = 0,006) tumor stage according to TNM system, the presence of metastasis (p = 0.063), and male gender (p = 0.066) were found to affect overall mortality (OM). On multivariable Cox regression analysis of these results, MLR (p = 0.005) and T stage (p = 0.006) was determined to be a statistically significant and independent prognostic value. In patients over 60 years of age who underwent surgery for gastric cancer, the factors affecting mortality were determined to be the presence of metastases, number of pathological lymph nodes, and male gender. Metastatic lymph node ratio and T1&T2 stage were determined to be independent prognostic factors. Elderly, Gastric cancer, Mortality, Prognostic factor.

This study was undertaken to evaluate conventional and some of the main bio-functional spermatozoa parameters, serum gonadal hormones and didymo-epididymal ultrasound features in patients with type 1 diabetes mellitus (DM1). DM1 affects an increasing number of men of reproductive age. Diabetes may affect male reproduction by acting on the hypothalamic-pituitary-testicular axis, causing sexual dysfunction or disrupting male accessory gland function. However, data on spermatozoa parameters and other aspects of the reproductive function in these patients are scanty. Thirty-two patients with DM1 [27.0 (25.0-30.0 years)] and 20 age-matched fertile healthy men [28.0 (27.25-30.75 years)] were enrolled. Patients with diabetic neuropathy, other endocrine disorders or conditions known to alter spermatozoa parameters were excluded. Each subject underwent semen analysis, blood withdrawal for fasting and post-prandial glycaemia, hormonal analysis and didymo-epididymal ultrasound evaluation before and after ejaculation. Patients with DM1 had a lower percentage of spermatozoa with progressive motility [10.0 (7.0-12.75) vs. 45.0 (42.0-47.75) %; p < 0.01] and a higher percentage of spermatozoa with abnormal mitochondrial function than controls [47.0 (43.0-55.0) vs. 2.0 (1.0-5.0) %; p < 0.01]. Patients also had greater post-ejaculatory diameters of cephalic [11.5 (10.2-13.6) vs. 6.0 (4.0-7.0) mm; p < 0.01] and caudal epididymis [5.5 (4.00-7.55) vs. 3.0 (2.0-4.0) mm; p < 0.01] compared to controls, suggesting a lack of the physiological post-ejaculation epididymal shrinkage. Correlation analysis suggested that progressive motility was associated with fasting glucose (r = -0.68; p < 0.01). The other parameters did not show any significant difference. Patients with DM1 had a lower percentage of spermatozoa with progressive motility, impaired mitochondrial function and epididymal post-ejaculatory dysfunction. These findings may explain why patients with DM1 experience fertility

This paper presents the results of a descriptive survey assessing male patients' past experience, current preferences, and concerns regarding the gender of the physician performing the male genital/rectal exam. The sample consists of 72 male patients seen at a university-based family practice clinic located in a small rural community in Michigan. Patient age and physician gender preference were the main independent variables of interest. This study found that 51.5% of all male patients in the sample indicated a preference for a male physician to perform the genital exam while 48.5% indicated no preference for physician gender. In contrast, for the rectal exam, 61.5% of all male patients indicated no preference for physician gender while 38.5% did express a preference for a male physician. No one expressed a preference for a female physician for either the genital or rectal exams. Further analysis revealed that male patients over the age of 40 who prefer a male physician do so, at least in part, because it would be embarrassing to have a female physician perform the exam. Few, however, would refuse to allow a female physician to perform the exam. Respondents preferred certain positions for the exam and these are a means of minimizing potential embarrassment in the older patient.

Neutropenia encompasses a family of neutropenic disorders, both permanent and intermittent, ranging from severe (<500 neutrophils/mm(3)) to mild (500-1500 neutrophils/mm(3)), which may also affect other organ systems such as the pancreas, central nervous system, heart, muscle and skin. Neutropenia can lead to life-threatening pyogenic infections whose severity is roughly inversely proportional to the circulating neutrophil counts.When neutropenia is detected, an attempt should be made to establish the etiology, and to distinguish acquired forms (the most frequent, including post viral neutropenia and autoimmune neutropenia) and congenital forms (rare disorders) that may be either isolated or part of a complex rare genetic disease. We report on a male patient initially diagnosed with isolated neutropenia who later turned out to be affected with Barth syndrome, a rare complex inherited disorder.

Patient reported outcome measures (PROMs) were used to evaluate outcomes of the artificial urinary sphincter (AUS) and the AdVance™ (American Medical Systems, Minnetonka, MN, US) male sling system (AVMS) for the symptomatic management of male stress urinary incontinence. All male patients with stress urinary incontinence referred to our specialist clinic over a two-year period completed the ICIQ-UI SF (International Consultation on Incontinence Questionnaire on Urinary Incontinence Short Form) and the ICIQ-MLUTS LF (International Consultation on Incontinence Questionnaire on Male Lower Urinary Tract Symptoms Long Form) at consultation as well as at subsequent follow-up appointments. The Wilcoxon signed-rank test for non-parametric paired data was used for pre and postoperative comparisons. The chi-squared test was used for categorical variables. Thirty-seven patients (forty surgical cases) completed a preoperative and at least one follow-up questionnaire. There was a statistically significant improvement in PROMs postoperatively, regardless of mode of surgery (p<0.01). Analysis of the ICIQ-MLUTS LF showed that patients with higher preoperative scores (>25) had greater improvement with an AUS than with the AVMS (p<0.01). This prospective study shows that completion and collection of PROMs as part of routine clinical practice is achievable and useful in the assessment of male stress incontinence surgery. PROMs are important instruments to assess effectiveness of healthcare intervention and they are useful adjuncts in surgical studies.

Many male reproductive system problems could be perceived as being embarrassing, which may be one of the reasons that they are often not identified in general practice. This article provides an overview of some common problems affecting the male reproductive system, and outlines current treatment options. Erectile dysfunction, premature ejaculation, loss of libido, testicular cancer and prostate disease may cause embarrassment to the patient and, occasionally, the general practitioner. We describe how patients affected by these conditions may present to general practice, and discuss the reasons why they may not present. We also discuss how GPs can overcome difficulties in identifying and dealing with their male patients suffering from male reproductive system issues.

Impairment of higher cognitive functions in patients with schizophrenia might stem from perturbation of more basic functions, such as processing speed. Various clinical symptoms might affect cognitive efficiency as well. Notably, previous research has revealed the role of affective symptoms on memory performance in this population, and suggested sex-specific effects. We conducted a post-hoc analysis of an extensive neuropsychological study of 88 patients with schizophrenia. Regression analyses were conducted on verbal memory and verbal fluency data to investigate the contribution of semantic organisation and processing speed to performance. The role of negative and affective symptoms and of attention disorders in verbal memory and verbal fluency was investigated separately in male and female patients. Semantic clustering contributed to verbal recall, and a measure of reading speed contributed to verbal recall as well as to phonological and semantic fluency. Negative symptoms affected verbal recall and verbal fluency in the male patients, whereas attention disorders affected these abilities in the female patients. Furthermore, depression affected verbal recall in women, whereas anxiety affected it in men. These results confirm the association of processing speed with cognitive efficiency in patients with schizophrenia. They also confirm the previously observed sex-specific associations of depression and anxiety with memory performance in these patients, and suggest that negative symptoms and attention disorders likewise are related to cognitive efficiency differently in men and women.

The prevalence of depressive affect is not well defined in the incident hemodialysis (HD) population. We investigated the prevalence of and associated risk factors and hospitalization rates for depressive affect in incident HD patients. We performed a prospective investigation using the Patient Health Questionnaire 2 (PHQ2) depressive affect assessment. From January to July of 2013 at 108 in-center clinics randomly selected across tertiles of baseline quality measures, we contacted 577 and 543 patients by telephone for depressive affect screening. PHQ2 test scores range from 0 to 6 (scores  ≥3 suggest the presence of depressive affect). The prevalence of depressive affect was measured at 1-30 and 121-150 days after initiating HD; depressive affect risk factors and hospitalization rates by depressive affect status at 1-30 days after starting HD were computed. Of 1120 contacted patients, 340 completed the PHQ2. In patients screened at 1-30 or 121-150 days after starting HD, depressive affect prevalence was 20.2% and 18.5%, respectively (unpaired t -test, P = 0.7). In 35 patients screened at both time points, there were trends for lower prevalence of depressive affect at the end of incident HD, with 20.0% and 5.7% of patients positive for depressive affect at 1-30 and 121-150 days, respectively (paired t -test, P = 0.1). Hospitalization rates were higher in patients with depressive affect during the first 30 days, exhibiting 1.5 more admissions (P < 0.001) and 10.5 additional hospital days (P = 0.008) per patient-year. Females were at higher risk for depressive affect at 1-30 days (P = 0.01). The prevalence of depressive affect in HD patients is high throughout the incident period. Rates of hospital admissions and hospital days are increased in incident HD patients with depressive affect.

Soluble carbon nanotubes show promise as materials for in vivo delivery and imaging applications. Several reports have described the in vivo toxicity of carbon nanotubes, but their effects on male reproduction have not been examined. Here, we show that repeated intravenous injections of water-soluble multiwalled carbon nanotubes into male mice can cause reversible testis damage without affecting fertility. Nanotubes accumulated in the testes, generated oxidative stress and decreased the thickness of the seminiferous epithelium in the testis at day 15, but the damage was repaired at 60 and 90 days. The quantity, quality and integrity of the sperm and the levels of three major sex hormones were not significantly affected throughout the 90-day period. The fertility of treated male mice was unaffected; the pregnancy rate and delivery success of female mice that mated with the treated male mice did not differ from those that mated with untreated male mice.

Objectives In the current study, we aimed to investigate the impact of childhood trauma on suicidal behaviour phenotypes in a group of patients with diagnosed affective disorder (unipolar or bipolar affective disorder). Patients and Methods Patients with and without a history of childhood abuse, measured by Childhood Trauma Questionnaire (CTQ), were assessed to explore risks for suicidal behaviour (including suicide attempt, self-harm and non-suicidal self-injury). The tested sample consisted of 258 patients (111 males and 147 females, in-patients and out-patients at the Department of Psychiatry and Psychotherapy, Medical University of Vienna and University Hospital Tulln, Lower Austria). Psychiatric diagnoses were derived from the SCAN (Schedules for Clinical Assessment in Neuropsychiatry) interview. In addition, patients were administered the Lifetime Parasuicidal Count (LPC), Suicidal Behaviour Questionnaire (SBQ-R), and Viennese Suicide Risk Assessment Scale (VISURIAS) questionnaires. Results In contrast to male suicide attempters, female suicide attempters showed both significantly higher total CTQ scores (p<0.001), and higher CTQ subscores (emotional, physical and sexual abuse, as well as emotional and physical neglect) in comparison to the non-suicidal control group. Besides, females with a history of self-harming behaviour (including suicidal intention) and Non-Suicidal-Self Injury (NSSI) had significantly higher CTQ total scores (p<0.001) than the control group. Conclusion These findings suggest gender differences in suicidal behaviour after being exposed to childhood trauma. PMID:26366559

Background Numerous studies show the existence of a high prevalence of cannabis use among patients with psychosis. However, the differences between men and women who debut with a first episode of psychosis (FEP) regarding cannabis use have not been largely explored. The aim of this study was to identify the specific sex factors and differences in clinical evolution associated with cannabis use. Method Sociodemographic characteristics at baseline were considered in our sample of FEP patients to find differences depending on sex and the use of cannabis. Clinical, functional and neurocognitive variables at baseline, 1-year, and 3-years follow-up were also explored. Results A total of 549 patients, of whom 43% (N = 236) were cannabis users, 79% (N = 186) male and 21% (N = 50) female, were included in the study. There was a clear relationship between being male and being a user of cannabis (OR = 5.6). Cannabis users were younger at illness onset. Longitudinal analysis showed that women significantly improved in all three dimensions of psychotic symptoms, both in the subgroup of cannabis users and in the non-users subgroup. Conversely, subgroups of men did not show improvement in the negative dimension. In cognitive function, only men presented a significant time by group interaction in processing speed, showing a greater improvement in the subgroup of cannabis users. Conclusion Despite knowing that there is a relationship between cannabis use and psychosis, due to the high prevalence of cannabis use among male FEP patients, the results showed that there were very few differences in clinical and neurocognitive outcomes between men and women who used cannabis at the start of treatment compared to those who did not.

One of the predicted consequences of climate change is a shift in body mass distributions within animal populations. Yet body mass, an important component of the physiological state of an organism, can affect key life-history traits and consequently population dynamics. Over the past decades, the wandering albatross—a pelagic seabird providing bi-parental care with marked sexual size dimorphism—has exhibited an increase in average body mass and breeding success in parallel with experiencing increasing wind speeds. To assess the impact of these changes, we examined how body mass affects five key life-history traits at the individual level: adult survival, breeding probability, breeding success, chick mass and juvenile survival. We found that male mass impacted all traits examined except breeding probability, whereas female mass affected none. Adult male survival increased with increasing mass. Increasing adult male mass increased breeding success and mass of sons but not of daughters. Juvenile male survival increased with their chick mass. These results suggest that a higher investment in sons by fathers can increase their inclusive fitness, which is not the case for daughters. Our study highlights sex-specific differences in the effect of body mass on the life history of a monogamous species with bi-parental care. PMID:28469021

23 patients (18 male and 5 female) aged 21-70 years who displayed male pattern hair loss (MPHL) in Stage 1 to Stage 5 as determined by the Norwood-Hamilton classification scale, and female pattern hair loss (FPHL) in Stage 1 to Stage 2 as determined by the Ludwig classification scale, were treated with non-activated autologous platelet-rich plasma (A-PRP). Autologous blood (55 mL) was harvested using sodium citrate as an anticoagulant. A-PRP (23 mL) was produced for all cases using a closed system according to the transfusion service protocol. Following centrifugation (260 x g for 10 min) the A-PRP was inserted in a laser light selector device, and after the centrifugation, 9 mL of A-PRP was collected. The scalp of the patients affected by androgenetic alopecia (AGA) was divided into four areas (frontal, parietal, vertex, and occipital); local anesthesia was not performed. Interfollicular A-PRP injections (0.2 mL x cm 2 ) were performed by controlled and mechanical injections scheduled at a depth of 5 mm using a medical injector gun. Treatment sessions were performed with a 30-day interval. For each patient, three treatment sessions were performed. PRP was injected in the androgen-related areas of scalp affected by hair loss. Placebo (normal saline solution) was loaded in another syringe (10 mL) and injected on the adjacent side in a similar fashion.

Contamination of groundwater by inorganic arsenic is one of the major public-health problems in Bangladesh. This cross-sectional study was conducted (a) to evaluate the quality of life (QOL) and mental health status of arsenic-affected patients and (b) to identify the factors associated with the QOL. Of 1,456 individuals, 521 (35.78%) were selected as case and control participants, using a systematic random-sampling method. The selection criteria for cases (n=259) included presence of at least one of the following: melanosis, leucomelanosis on at least 10% of the body, or keratosis on the hands or feet. Control (nonpatient) participants (n=262) were selected from the same villages by matching age (±5 years) and gender. The Bangladeshi version of the WHOQOL-BREF was used for assessing the QOL, and the self-reporting questionnaire (SRQ) was used for assessing the general mental health status. Data were analyzed using Student's t-test and analysis of covariance (ANCOVA), and the WHOQOL-BREF and SRQ scores between the patients and the non-patients were compared. The mean scores of QOL were significantly lower in the patients than those in the non-patients of both the sexes. Moreover, the mental health status of the arsenic-affected patients (mean score for males=8.4 and females=10.3) showed greater disturbances than those of the non-patients (mean score for males=5.2 and females=6.1) of both the sexes. The results of multiple regression analysis revealed that the factors potentially contributing to the lower QOL scores included: being an arsenic-affected patient, having lower age, and having lower annual income. Based on the findings, it is concluded that the QOL and mental health status of the arsenic-affected patients were significantly lower than those of the non-patients in Bangladesh. Appropriate interventions are necessary to improve the well-being of the patients.

Patients' satisfaction with male versus female physicians: a meta-analysis.

Female physicians have a more patient-centered practice style than male physicians, and patient satisfaction is predicted by a more patient-centered practice style. To assess whether there is a difference in patients' satisfaction with male versus female physicians and to examine moderators of this effect. MEDLINE and PsycINFO databases and citation search through 2009, using keywords pertaining to patient satisfaction and physician sex. English-language articles that compared patients' satisfaction in relation to their physicians' sex. Only studies of actual patients and physicians, including postgraduate trainees, were included. Forty-five studies reporting 28 effect sizes met inclusion criteria. Two coders independently extracted effect sizes (point-biserial correlations) and coded study attributes, then resolved disagreements through discussion. The satisfaction difference between male and female physicians was extremely small (r < 0.04), but was statistically significant (P < 0.05) in a random effects model. Significant moderators showed that the difference favored female physicians most when physicians were less experienced, when physicians and patients were newly acquainted, when satisfaction pertained to a specific visit, when satisfaction was measured right after a visit, and when patients were younger. There was also significant variation depending on where satisfaction was measured. Female physicians are not evaluated as highly by their patients, relative to male physicians, as one would expect based on their practice style and patients' values. Reasons for this disparity are discussed.

BACKGROUND Doctors' empathy is closely related to patients' health. This study aimed to examine whether patients' stigma and self-efficacy play a mediating role in the relationship between doctors' empathy abilities and patients' cellular immunity in male patients with breast cancer. MATERIAL AND METHODS Doctors' empathy scores and patients' demographic data, disease condition, stigma, and self-efficacy were measured. Patient T cell subset was tested at admission and 3 months after the operation and was compared by paired t test. The multivariate linear regression model was applied to analyze the factors influencing the immune index. Pearson correlation analysis and structural equation modeling were applied to explore the relationships among patients' stigma, self-efficacy, and cellular immunity and doctors' empathy abilities. RESULTS At the 2 time points, only the change in NK subset was statistically significant, while the changes in percentage of CD3+, CD4+, CD8+, and B cells were not statistically significant. The doctors' empathy abilities were negatively correlated with patients' stigma and were positively related to patients' self-efficacy. Patients' stigma was negatively related to NK subset, while self-efficacy was positively associated with NK subset. Patients' stigma and self-efficacy played a mediating role in the relationship between doctors' empathy abilities and patients' NK subset, and stigma had a stronger effect than self-efficacy. CONCLUSIONS Doctors' empathy abilities affected breast cancer patients' NK subset through their stigma and self-efficacy. The mental health of male breast cancer patients need more attention and empathy education needs to be improved.

Female remating in target pest species can affect the efficacy of control methods such as the Sterile Insect Technique (SIT) but very little is known about the postcopulatory mating behavior of these pests. In this study, we investigated the remating behavior of female Anastrepha serpentina (Diptera: Tephritidae), an oligophagous pest of Sapotaceae. First, we tested how long the sexual refractory period of females lasted after an initial mating. Second, we tested the effect of male and female sterility, female ovipositing opportunities and male density on female propensity to remate. Lastly, we tested if the amount of sperm stored by females was correlated to the likelihood of females to remate. We found that receptivity of mass-reared A. serpentina females had a bimodal response, with up to 16% of mass-reared A. serpentina females remating five days after the initial copulation, decreasing to 2% at 10 and 15 days and increasing to 13% after 20 days. Compared to fertile males, sterile males were less likely to mate and less likely to inhibit females from remating. Copula duration of sterile males was shorter compared to fertile males. Remating females were less likely to mate with a sterile male as a second mate. Sterile females were less likely to mate or remate compared to fertile females. Opportunity to oviposit and male density had no effect on female remating probability. Sperm numbers were not correlated with female likelihood to remate. Information on the post-copulatory behavior of mass-reared A. serpentina will aid fruit fly managers in improving the quality of sterile males. We discuss our results in terms of the differences this species presents in female remating behavior compared to other tephritids. Copyright © 2015 Elsevier Ltd. All rights reserved.

In psychiatric nursing, female nurses tend to spend more time building rapport with patients and developing cooperative working relationships with colleagues; they encounter more sexual harassment by patients. In contrast, male nurses respond to aggressive patients and tend to resist physically caring for female patients; they encounter more physical and verbal assault from patients. These gender differences might result in differences in job-related stress. We quantitatively examined gender differences in psychiatric nurses' job stress. The Psychiatric Nurse Job Stressor Scale and the Stress Reaction Scale of the Brief Job Stress Questionnaire were administered to 159 female and 85 male Japanese psychiatric nurses. The results indicated that female nurses had significantly higher stress levels than males related to psychiatric nursing ability, attitude towards nursing, and stress reactions of fatigue and anxiety. Moreover, the factors affecting stress reactions differed somewhat between sexes. In particular, male nurses reported that greater irritability was affected by patients' attitudes. Their anxiety and somatic symptoms were affected by their attitude towards nursing, and depressed mood was affected by psychiatric nursing ability. Knowledge of these differences can lead to better mental health-care interventions for psychiatric nurses. © 2014 Australian College of Mental Health Nurses Inc.

Fabry disease (FD) is an X-linked lysosomal storage disorder caused by the deficiency of alpha-galactosidase A. In addition to the debilitating physical symptoms of FD, there are also under-recognized and poorly characterized psychiatric features. As a first step toward characterizing psychiatric features of FD, we administered the Achenbach adult self report questionnaire to 30 FD patients and the Achenbach adult behavior checklist questionnaire to 28 partners/parents/friends of FD patients. Data from at least one of the questionnaires were available on 33 subjects. Analysis focused on social-adaptive functioning in various aspects of daily life and on criteria related to the Diagnostic and statistical manual of mental disorders IV (DSM-IV). Adaptive functioning scale values, which primarily measure social and relationship functioning and occupational success, showed that eight FD patients (six female and two male) had mean adaptive functioning deficits as compared to population norms. Greater rates of depression (P < 0.01), anxiety (P = 0.05), depression and anxiety (P = 0.03), antisocial personality (P < 0.001), attention-deficit/hyperactivity (AD/H; P < 0.01), hyperactivity-impulsivity (P < 0.01), and aggressive behavior (P = 0.03) were associated with poorer adaptive functioning. Decreased social-adaptive functioning in this study was not statistically significantly associated to disease severity, pain, or level of vitality. This study shows for the first time that FD patients, particularly women, are affected by decreased social-adaptive functioning. Comprehensive treatment plans for FD should consider assessments and interventions to evaluate and improve social, occupational, and psychological functioning. Attention to the behavioral aspects of FD could lead to improved treatment outcome and improved quality of life. Individuals affected by Fabry disease exhibited social-adaptive functioning deficits that were significantly correlated with anxiety

This article explores the therapeutic relationship between male nursing students and female patients, through the use of autobiography in a qualitative approach. For this study, 18 male nursing students enrolled in master's and bachelor's programs in Hong Kong were recruited. They were asked to make records in a diary and draw pictures of their therapeutic relationship with female patients from their clinical experiences and then participate in a focus group interview. Content analysis was carried out on the collected data. The essential factors influencing the development of a therapeutic relationship were found to be gender, symbolic meanings, and career features. Good experiences were also discussed. The results shed light on the experiences of male nursing students and how they make sense of their therapeutic relationship with female patients. © The Author(s) 2013.

Summary Smoking adversely affects hematopoietic stem cell transplantation outcome. We asked whether smoking affected outcome of newly diagnosed acute myeloid leukemia (AML) patients treated with chemotherapy. Data were collected on 280 AML patients treated with high-dose cytarabine and idarubicin-containing regimens at Roswell Park Cancer Institute who had smoking status data at diagnosis. Patients’ gender, age, AML presentation (de novo vs. secondary), white blood cell (WBC) count at diagnosis, karyotype and smoking status (never vs. ever) were analyzed. Among the 161 males and 119 females with a median follow-up of 12.9 months, 101 (36.1%) had never smoked and 179 (63.9%) were ever smokers. The proportion of patients between never and ever smokers was similar with respect to age, AML presentation, WBC count at diagnosis or karyotype based on univariate analysis of these categorical variables. Never smokers had a significantly longer overall survival (60.32 months) compared to ever smokers (30.89; p=0.005). In multivariate analysis incorporating gender, age, AML presentation, WBC count, karyotype, and smoking status as covariates, age, karyotype and smoking status retained prognostic value for overall survival. In summary, cigarette smoking has a deleterious effect on overall survival in AML. PMID:21520043

The purpose of the current study was to describe male breast cancer in Johannesburg, South Africa, and assess whether male breast cancer patients' perception of their own masculinity was affected by having a cancer commonly seen in women. A retrospective file review was carried out at two hospitals, one private and one government, of male breast cancer patients from 2007 to 2012 followed by a telephone survey of patients identified during review. Of approximately 3,000 breast cancer patients seen in the 5 years reviewed, 23 cases of male breast cancer were identified. Most were diagnosed with invasive ductal carcinoma ( n = 19, 83%). Stage at presentation was from stages 0 to 3 (Stage 0 [ n = 2, 9%], Stage 1 [ n = 3, 13%], Stage 2 [ n = 12, 52%], Stage 3 [ n = 6, 26%]) and no patients were metastatic at presentation. The telephonic survey was completed by 18 patients (78%). Nearly all ( n = 17/18) shared their diagnosis with family and close friends. Two thirds of patients delayed presentation and government hospital patients were more likely to present later than private sector hospital patients. Although most male breast cancer patients sampled did not perceive the breast cancer diagnosis as affecting their masculinity, Black men and those treated in government hospitals were less likely to be aware of male breast cancer, and were more likely to have their perception of their own masculinity affected.

Imatinib is a first-line tyrosine kinase inhibitor for treating chronic myelogenous leukaemia (CML) and has greatly improved the prognosis of this disease. An increasing number of CML patients of reproductive age are diagnosed each year, and the impact of imatinib on fertility is a major concern. Providing useful advice to these patients regarding the choice of their therapeutic treatment is very important. This study examined the impact of imatinib on the fertility of male patients with CML in the chronic phase. We performed a study of 48 adult male CML patients in the chronic phase (CML-CP), 50 healthy control subjects, and 10 male patients with infertility. Imatinib levels in semen and plasma were measured using high-performance liquid chromatography/mass spectrometry. We examined the effects of imatinib on sperm parameters and the male reproductive system using a computer-assisted sperm assay and ultrasound, respectively. We analysed sex hormone levels in the sera of CML-CP patients using an enzyme-linked immunosorbent assay. Imatinib levels in semen were comparable to plasma levels in CML-CP patients. CML-CP patients treated with imatinib exhibited reduced sperm density, counts, survival rates, and activity. Ultrasound demonstrated that the shape and size of the testis and epididymis in CML-CP patients undergoing imatinib treatment were normal. However, 19 of these patients exhibited a hydrocele in their tunica vaginalis, with a large dark area of effusion (0.7-2.9 cm in width). Sex hormone levels in the sera of the CML-CP patients were normal. These results suggest that imatinib crosses the blood-testis barrier and reduces sperm density, sperm count, survival rates, and activity in CML-CP patients. However, imatinib did not affect the structure of reproductive organs or sex hormone levels.

Summary An individual’s sex has been long recognized as a key factor affecting cancer incidence, prognosis and treatment responses. However, the molecular basis for sex disparities in cancer remains poorly understood. We performed a comprehensive analysis of molecular differences between male and female patients in 13 cancer types of The Cancer Genome Atlas and revealed two sex-effect groups associated with distinct incidence and mortality profiles. One group contains a small number of sex-affected genes, whereas the other shows much more extensive sex-biased molecular signatures. Importantly, 53% of clinically actionable genes (60/114) show sex-biased signatures. Our study provides a systematic molecular-level understanding of sex effects in diverse cancers and suggests a pressing need to develop sex-specific therapeutic strategies in certain cancer types.

To identify problems in the long-term psychosocial and developmental outcome specific to patients with the bladder exstrophy-epispadias complex (BEEC), using a self-developed semi-structured questionnaire, as there are various techniques of reconstruction to repair BEEC but to date neither patients nor surgeons have a clear answer about which type gives the most acceptable long-term results. Increasingly many patients with BEEC reach adulthood and wish to have sexual relationships and families. To date, no studies have used disease-specific psychological instruments to measure the psychosocial status of patients with BEEC. Thus we contacted 208 patients with BEEC, and 122 were enrolled, covering the complete spectrum of the BEEC. The data assessed included the surgical reconstruction, subjective assessment of continence, developmental milestones, school performance and career, overall satisfaction in life, disease-specific fears and partnership experiences in patients aged >18 years. We compared affected females and males to assess gender-associated differences in quality of life. Affected females had more close friendships, fewer disadvantages in relation to healthy female peers and more partnerships than the males. Family planning seemed to be less of a problem in affected females. There were no gender differences in the adjustments within school and professional career, which was very good in general. Future studies are needed to assess the disease-specific anxieties, considering gender-specific differences.

How patient-centered do female physicians need to be? Analogue patients' satisfaction with male and female physicians' identical behaviors.

Previous research suggests that female physicians may not receive appropriate credit in patients' eyes for their patient-centered skills compared to their male counterparts. An experiment was conducted to determine whether a performance of higher (versus lower) verbal patient-centeredness would result in a greater difference in analogue patient satisfaction for male than female physicians. Two male and two female actors portrayed physicians speaking to a patient using high or low patient-centered scripts while not varying their nonverbal cues. One hundred ninety-two students served as analogue patients by assuming the patient role while watching one of the videos and rating their satisfaction and other evaluative responses to the physician. Greater verbal patient-centeredness had a stronger positive effect on satisfaction and evaluations for male than for female physicians. This pattern is consistent with the hypothesis that the different associations between patient-centeredness and patients' satisfaction for male versus female physicians occur because of the overlap between stereotypical female behavior and behaviors that comprise patient-centered medical care. If this is the case, high verbal patient-centered behavior by female physicians is not recognized as a marker of clinical competence, as it is for male physicians, but is rather seen as expected female behavior.

While males and females are equally at risk of sudden cardiac arrest (SCA), females are less likely to be resuscitated. Cardiopulmonary Resuscitation (CPR) may be inhibited by socio-cultural norms about exposing female victims' chests. Empirically confirming this hypothesis is limited by lack of patient simulators modeling realistic female physiques. A commercially-available patient simulator was transformed to evaluate how physical attributes of a patient's sex might influence lay participants who were asked to resuscitate a female versus a male during simulated cardiac arrest. Sixty-nine participants consented to be in the study. Participants were randomly assigned to provide CPR and defibrillation as instructed by a commercially-available automated external defibrillator on a patient simulator presented as either a male or female experiencing cardiac arrest. Rescuers removed significantly more clothing from the male than the female, with men removing less clothing from the female. More rescuers' initial hand placements for CPR were centered between the female's breasts compared to the male, on which placement was distributed across the chest towards the nipples. While rescuers had better hand placement for CPR on the female, both men and women rescuers were reluctant to remove the female's clothing, with men significantly more hesitant. Reticence to remove clothing was often articulated relative to social norms during structured interviews. We suggest that using only male simulators will not allow trainees to experience social differences associated with the care of a female simulated patient. Realistic female patient simulators are needed. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Objectives: This study aimed to find the factors that affect dental esthetics and smile attractiveness in orthodontically treated patients according to laypeople’s judgment, and to determine whether there is any relationship between dental and smile esthetics. Materials and Methods: Using the Q-sort technique, 60 laypersons (30 males, 30 females) rated dental and smile photographs of 48 orthodontically treated patients based on their degree of attractiveness. Dental and smile parameters of each rated image were measured by Smile Analyzer software. The Student’s t-test and chi-square test were used to compare dental and smile parameters between attractive and unattractive images. The logistic regression was used to assess which variables predicted dental and smile esthetics in treated individuals. Results: The philtral to commissural height ratio and gingival display were significantly different in attractive and unattractive smiles (P=0.003 and P=0.02, respectively). None of the dental variables were found to be a determinant of dental esthetics at the end of the orthodontic treatment (P>0.05). According to the judgment of all raters (female and male) and the male raters’ judgment, smile attractiveness could be predicted by philtral to commissural height ratio and buccal corridor ratio (P<0.05). There was no statistically significant relationship between dental esthetics and smile attractiveness in orthodontically treated patients (P>0.05). Conclusion: The philtral to commissural height ratio and buccal corridor ratio can be considered as predictors of smile attractiveness in orthodontically treated patients. Achieving dental esthetics at the end of orthodontic treatment does not guarantee smile attractiveness. PMID:26877739

Total knee arthroplasty (TKA) in limbs affected by poliomyelitis is a technically challenging procedure. These patients often demonstrate acquired articular and metaphyseal angular deformities, bone loss, narrowness of the intramedullary canals, impaired quadriceps strength, flexion contractures and ligamentous laxity producing painful hyperextension. Thus, using condylar knee designs in these patients will likely result in early failure because of instability and abnormal load distribution. The aim of this study was to assess the outcomes associated with use of the customised (SMILES) rotating-hinge knee system at our institution for TKA in poliomyelitis-affected limbs. We retrospectively reviewed the outcome of 14 TKAs using the (SMILES) prosthesis in 13 patients with limbs affected by poliomyelitis. All patients had painful unstable knees with hyperextension. There were ten females and three males with a mean age of 66 years (range 51-84) at time of surgery. Patients were followed up clinically, radiologically and functionally with the Oxford knee score (OKS). Mean follow-up was 72 months (16-156). There were no immediate or early complications. One patient fell and sustained a peri-prosthetic fracture at seven months requiring revision to a longer stem. Radiological evaluation showed satisfactory alignment with no signs of loosening in all cases. Mean OKS improved from 11.6 (4-18) to 31.5 (18-40) postoperatively (p < 0.001). The rotating hinge (SMILES) prosthesis is effective at relieving pain and improving function in patients with poliomyelitis. The device compensates well for ligamentous insufficiency as well as for any associated bony deformity.

Background Multiple sclerosis (MS) is a demyelinating disease which can cause many disabilities for the patient. Recent data suggests that MS patients have higher risk for osteoporosis. This study was performed to investigate if the osteoporosis prevalence is higher in MS patients and to determine the possible factors affecting bone mineral density (BMD). Methods 51 definite relapsing-remitting MS patients according to McDonald's criteria (45 females, 6 males aged between 20 and 50 years) participated in this study. The control group included 407 females aged from 20 to 49 years; they were healthy and had no history of the diseases affecting bone metabolism. Femoral and lumbar BMD were measured by Dual Energy X-ray Absorptiometry (DXA). The disability of MS patients was evaluated by Expanded Disability Status Scale (EDSS). The patient's quality of life was evaluated by the validated Persian version of multiple sclerosis impact scale (MSIS-29). Results Patients’ mean age was 36 ± 3.3 years and their mean disease duration was 8.7 ± 1.7 years. The mean EDSS score and the mean body mass index (BMI) of the patients were 3 ± 0.9 and 23.5 ± 2.3 kg/m2, respectively. 29% of the patients had never been treated by ß-interferon and 6% of them had not received glucocorticoids (GCs) pulses since their MS had been diagnosed. 26% of the patients had a history of fracture.18% of our patients were osteoporotic and 43% of them were osteopenic. Femoral BMD was significantly lower among MS patients than age matched controls (P < 0.001), but lumbar BMD showed no difference. There was no correlation between administration of GCs pulses, interferon and BMD; however, we found a significant correlation between EDSS score, quality of life (QoL), disease duration and BMD of both site. Conclusion As a result of this study, bone loss inevitably occurs in MS patients. The major factor of BMD loss is immobility. Osteoporosis should be managed as part of MS patients’ treatment protocols

Personality differentially affects individual mate choice decisions in female and male Western mosquitofish (Gambusia affinis).

Consistent individual differences in behavioral tendencies (animal personality) can affect individual mate choice decisions. We asked whether personality traits affect male and female mate choice decisions similarly and whether potential personality effects are consistent across different mate choice situations. Using western mosquitofish (Gambusia affinis) as our study organism, we characterized focal individuals (males and females) twice for boldness, activity, and sociability/shoaling and found high and significant behavioral repeatability. Additionally, each focal individual was tested in two different dichotomous mate choice tests in which it could choose between computer-animated stimulus fish of the opposite sex that differed in body size and activity levels, respectively. Personality had different effects on female and male mate choice: females that were larger than average showed stronger preferences for large-bodied males with increasing levels of boldness/activity (i.e., towards more proactive personality types). Males that were larger than average and had higher shoaling tendencies showed stronger preferences for actively swimming females. Size-dependent effects of personality on the strength of preferences for distinct phenotypes of potential mating partners may reflect effects of age/experience (especially in females) and social dominance (especially in males). Previous studies found evidence for assortative mate choice based on personality types or hypothesized the existence of behavioral syndromes of individuals' choosiness across mate choice criteria, possibly including other personality traits. Our present study exemplifies that far more complex patterns of personality-dependent mate choice can emerge in natural systems.

Depressive symptomatology has been connected with an activation of the hypothalamus-pituitary-adrenal axis and, in several studies, with reduced androgen levels, while administration of androgens, usually in older subjects, may have positive effects on mood, both in males and females. Regarding dysthymic disorder (DD), low serum testosterone levels have been reported in older males, while information on younger male or on female patients is lacking. We assessed the serum levels of testosterone (T), dehydroepiandrosterone sulfate (DHEAS) and cortisol in male and female patients with DD, and compared them to the levels of sex and age matched controls. Eighteen male and 43 female patients in the age range of 22 to 71 years were studied and diagnosed according to the Scheduled Diagnostic Interview for DSM-IV axis I disorders (SCID). Depressive symptomatology was assessed using the Hamilton Depression Rating Scale. Subgroups with subjects below or over 50 years of age were also built and compared. Serum T levels were lower than controls mainly in the subjects aged below 50 years, in both genders. More pronounced were reductions in DHEAS levels both in male and female patients, while cortisol levels were normal or reduced. T levels were positively correlated to both DHEAS and cortisol. The negative correlations of DHEAS and T to age were significant for all groups and subgroups, except in the group of male patients. Four male patients (22%) had T levels below 2.0 ng/ml. Male and female patients with DD aged below 50 years show reduced gonadal and adrenal androgen levels, and normal to low cortisol levels. These neuroendocrine characteristics differentiate DD from depression, and place this diagnostic group closer to posttraumatic stress disorder.

[Purpose] This study examined the quality of life (QOL) of homebound elderly hemiparetic stroke patients and factors that affect it. [Subjects] The subjects of the study were 21 homebound elderly hemiparetic stroke patients who were 65 years old or over and required care for daily living (12 males and 9 females, average age: 79.3 ± 8.4 years old). Their physical and psychological conditions, QOL, and other characteristics were researched. [Methods] The Functional Independence Measure (FIM) was used for the activities of daily living (ADL) assessment, and the MOS 36-Item Short-Form Health Survey (SF-36, Japanese version 1.2) was used for the QOL assessment. [Results] No correlations were observed between the QOL of homebound elderly hemiparetic stroke patients and their age and gender. However, the results showed that their QOL was affected by their independence in ADL, bedridden degree, and care-need level. [Conclusion] These results suggest that in order to improve the QOL of homebound elderly hemiparetic stroke patients, ongoing rehabilitation to improve independence in ADL and lower the bedridden degree and care-need level is required.

The location of facial port-wine stain (PWS) may be helpful for predicting some associated anomalies; high glaucoma incidence is found in patients with eyes close to PWS-affected areas (V1, ophthalmic branch area of the trigeminal nerve). This study aimed to investigate the characteristics of glaucoma in V1-affected PWS. A total of 569 patients with V1 area-affected PWS were reviewed in the study. The large series was based on the referral system between the Department of Plastic and Reconstructive Surgery and the Department of Ophthalmology. All patients were screened for glaucoma with assessments of intraocular pressure, cup-to-disc ratio, corneal diameter (only for infants), and axial length. Of the 569 patients, 110 (19.3%) patients had glaucoma. Among the patients, 18.1% (76/420) had early-onset glaucoma (under 4-year-old group). In the 4 to 18-year-old age group, 29.3% (29/99) of the patients had glaucoma. Compared with right lateral and bilateral PWS, left-sided PWS had a lower risk of glaucoma in this study (odds ratio = 0.432 [95% confidence interval, 0.264-0.706], P = 0.01). The under 4-year-old group showed a slight predominance of males (61.8%) in glaucoma. High glaucoma incidence was observed in patients with eyes close to PWS. More attention should be paid to glaucoma screening for right lateral and bilateral PWS patients. The predominance of males in Sturge-Weber syndrome (SWS) early-onset glaucoma patients might be due to the limitation of the case number; however, it might also provide us a new clue of potential relationship between SWS and PCG.

A retrospective file review was carried out at two hospitals, one private and one government, of male breast cancer patients from 2007 to 2012 followed by a telephone survey of patients identified during review. Of approximately 3,000 breast cancer patients seen in the 5 years reviewed, 23 cases of male breast cancer were identified. Most were diagnosed with invasive ductal carcinoma (n = 19, 83%). Stage at presentation was from stages 0 to 3 (Stage 0 [n = 2, 9%], Stage 1 [n = 3, 13%], Stage 2 [n = 12, 52%], Stage 3 [n = 6, 26%]) and no patients were metastatic at presentation. The telephonic survey was completed by 18 patients (78%). Nearly all (n = 17/18) shared their diagnosis with family and close friends. Two thirds of patients delayed presentation and government hospital patients were more likely to present later than private sector hospital patients. Although most male breast cancer patients sampled did not perceive the breast cancer diagnosis as affecting their masculinity, Black men and those treated in government hospitals were less likely to be aware of male breast cancer, and were more likely to have their perception of their own masculinity affected.

Many studies of patients' perception of a medical chaperone have focused on female patients; that of male patients are less well studied. Moreover, previous studies were largely based on patient populations in English-speaking countries. Therefore, this study was conducted to investigate the perception and attitude of male and female Chinese patients to the presence of a chaperone during an intimate physical examination. A cross-sectional guided questionnaire survey was conducted on a convenient sample of 150 patients at a public teaching hospital in Hong Kong. Over 90% of the participants considered the presence of a chaperone appropriate during intimate physical examination, and 84% felt that doctors, irrespective of gender, should always request the presence of a chaperone. The most commonly cited reasons included the availability of an objective account should any legal issue arise, protection against sexual harassment, and to provide psychological support. This contrasted with the experience of those who had previously undergone an intimate physical examination of whom only 72.6% of women and 35.7% of men had reportedly been chaperoned. Among female participants, 75.0% preferred to be chaperoned during an intimate physical examination by a male doctor, and 28.6% would still prefer to be chaperoned when being examined by a female doctor. Among male participants, over 50% indicated no specific preference but a substantial minority reported a preference for chaperoned examination (21.2% for male doctor and 25.8% for female doctor). Patients in Hong Kong have a high degree of acceptance and expectations about the role of a medical chaperone. Both female and male patients prefer such practice regardless of physician gender. Doctors are strongly encouraged to discuss the issue openly with their patients before they conduct any intimate physical examination.

The aim of this study was to compare physicians' weight loss goals for obese male and female patients. This study was conducted in 2008-2009 in Florida, USA. Physicians (N=108; 79.6% primary care specialty) reviewed two hypothetical clinical scenarios that were identical with respect to health status and obesity (BMI=33 kg/m(2)) but differed in the gender of the patient. Physicians then completed a survey about the need for weight loss, intentions to provide weight loss counseling, and weight loss goals (i.e., ideal, successful, and acceptable goal weights) for each hypothetical patient. Physicians strongly agreed that both patients should lose weight and physician counseling and/or treatment referrals would be appropriate; however, physician weight loss goals for male and female patients differed. BMI values calculated from the suggested ideal, successful, and acceptable weight goals were significantly lower for female patients than male patients, 22.0 vs. 25. 2 kg/m(2); 25.4 vs. 27. 8 kg/m(2); and 27.0 vs. 29. 2 kg/m(2), respectively, P values <.001. Physicians endorsed significantly more stringent weight loss goals for obese female patients than obese male patients. Regardless of patient gender, physician goals exceeded the 5-10% losses currently recommended. Additional research is needed to better understand this gender discrepancy in physician expectations for obese patients. Copyright 2010 Elsevier Inc. All rights reserved.

Subareolar breast abscess (SBA) is a rare infectious disease of the breast in male patients. Herein, we report two male patients with SBA. Patient 1 was initially diagnosed with a malignant tumor based on imaging findings; ultrasonography revealed a hypoechoic mass with blood flow. Patient 2 was diagnosed with inflammatory changes to his nipple; ultrasonography findings supported the diagnosis with an irregular hypoechoic mass with blood flow. Both patients received a cytological or histological biopsy preoperatively, which showed an abscess without malignant cells. These cases serve as an important reminder to consider complete resection of the tumor including the responsible mammary duct (tumor and duct resection (TDR)) for curative therapy of SBA.

Male hypogonadism is common in the elderly and has been associated with increased risk of mortality. Our objective has been to assess the prevalence of primary and central hypogonadism in elderly male patients admitted to the hospital because of acute illness. We also evaluated the relationships between gonadal dysfunction and in-hospital mortality. 150 patients, aged ≥65 years, admitted during 2010 and 2011 in our geriatric unit, were studied. Serum concentrations total, bioavailable and free testosterone, as well as of follicle-stimulating hormone and luteinizing hormone were quantified in every patient. Hypogonadism was defined by the presence of serum testosterone levels lower than 200 ng/dl. Hypogonadism was found in 80 patients (53.3 %). Serum gonadotropin concentrations were elevated in 43.7 % of these patients, whereas 41.3 % of hypogonadic patients showed normal and 15 % low gonadotropin concentrations. Respiratory tract infection and congestive heart failure were the main causes of hospitalization in hypogonadal men, whereas acute cerebrovascular disease was the main reason for admission in eugonadal patients. Of the 13 patients who died during hospitalization, 12 were hypogonadic. Patients who died showed significantly lower serum levels of total, free and bioavailable testosterone than those found in patients who survived. Our results show that about half of patients admitted for acute illness have hypogonadism, mainly of non-hypergonadotropic type. Gonadal hypofunction is significantly related with in-hospital mortality. A low value of serum testosterone may be a predictor for mortality in elderly male patients.

Sentinel node biopsy is a standard method for nodal staging in patients with clinically localized cutaneous melanoma, but the survival advantage of sentinel node biopsy remains unsolved. The aim of this case-control study was to investigate the survival benefit of sentinel node biopsy. A total of 305 prospective melanoma patients undergoing sentinel node biopsy were compared with 616 retrospective control patients with clinically localized melanoma whom have not undergone sentinel node biopsy. Survival differences were calculated with the median follow-up time of 71 months in sentinel node biopsy patients and 74 months in control patients. Analyses were calculated overall and separately in males and females. Overall, there were no differences in relapse-free survival or cancer-specific survival between sentinel node biopsy patients and control patients. Male sentinel node biopsy patients had significantly higher relapse-free survival ( P = 0.021) and cancer-specific survival ( P = 0.024) than control patients. In females, no differences were found. Cancer-specific survival rates at 5 years were 87.8% in sentinel node biopsy patients and 85.2% in controls overall with 88.3% in male sentinel node biopsy patients and 80.6% in male controls and 87.3% in female sentinel node biopsy patients and 89.8% in female controls. Sentinel node biopsy did not improve survival in melanoma patients overall. While females had no differences in survival, males had significantly improved relapse-free survival and cancer-specific survival following sentinel node biopsy.

Central pedicled breast reduction technique in male patients after massive weight loss.

2012-03-01

Male patients after massive weight loss often suffer from redundant skin and soft tissue in the anterior and lateral chest region, causing various deformities of pseudogynecomastia. Techniques with free or pedicled nipple-areola complex (NAC) transposition are widely accepted. The authors present their approach to male breast reduction with preservation of the NAC on a central dermoglandular pedicle and a wide elliptical tissue excision of breast and lateral thorax tissue in combination with liposuction. Male breast reduction was performed on patients after moderate to massive weight loss due to diet or bariatric procedures. Former procedures included free nipple-areola grafts or inferior pedicled techniques for NAC preservation. As a modification, we performed a central pedicled breast reduction on nine male patients with excessive liposuction of the pedicle and a horizontal elliptical skin removal, allowing for sufficient tissue removal at the lateral thorax. From October 2010 until June 2011, nine male patients had central pedicled breast reconstructions after massive weight loss. Mean age was 29.1 years, mean preoperative body mass index was 29.2, and mean preoperative weight loss was 63.9 kg. The chest wall improvement was rated "very good" by eight patients. No major complications occurred in all nine patients. Male chest deformities after massive weight loss can be dealt by several approaches. The optimal scar positioning and the preservation of NAC may be the most challenging aspects of these procedures. Therefore, the preservation of the NAC on a central dermoglandular pedicle with a horizontal submammary scar course may optimize the esthetic outcome.

An environmentally relevant endocrine-disrupting antiandrogen, vinclozolin, affects calling behavior of male Xenopus laevis.

Vinclozolin (VIN) is an antiandrogenic model substance as well as a common fungicide that can affect the endocrine system of vertebrates. The objective of this study was to investigate how VIN affects mate calling behavior of South African clawed frogs (Xenopus laevis) and whether it is effective at environmentally relevant concentrations. Male X. laevis were injected with human chorionic gonadotropin (hCG) to stimulate their androgen-controlled mate calling behavior and were treated with VIN at concentrations of 10(-6), 10(-8) and 10(-10)M. VIN at 10(-6)M reduced calling activity. Furthermore, the vocalization composition of VIN-treated X. laevis was altered. The call types advertisement calls and chirping are uttered by reproductively active males, whereas the call types growling, ticking, and rasping indicate a sexually unaroused state of a male. VIN at any of the tested concentrations led to a decrease in utterance of calls, which indicate a sexually aroused state of the males, and an increase in relative proportions of calls, indicating a sexually unaroused state of the males. Additionally, the mean duration of clicks and the number of accentuated clicks during the advertisement calls decreased at all concentrations of VIN. No significant differences were observed in any other temporal or spectral calling parameters between the treatments. This study illustrates that exposure to the antiandrogen VIN might result in a reduced reproductive success by altering mate calling behavior of X. laevis. Moreover, it suggests that the behavioral parameters examined in this study can be used as sensitive biomarkers for detecting antiandrogenic endocrine disrupting compounds in amphibians.

Obstructive uropathy due to advanced cancer can be efficiently treated with a percutaneous nephrostomy. The treatment is associated with complications and frequent readmissions. How the patients' quality of life is affected by a nephrostomy remains uncertain. The aim of this study was to describe how a nephrostomy is perceived by patients and its effects on their everyday lives. Semi-structured interviews were conducted in the patients' home using a mind map. The inclusion criteria were locally advanced or metastatic urological cancer treated with a nephrostomy for a minimum of 1 month. All interviews were audio recorded, transcribed and analysed using a grounded theory approach. Ten male patients were interviewed, eight with prostate cancer and two with bladder cancer. Treatment with nephrostomy influenced the physical activity level and restricted normal social activities. Readmissions had a negative influence on mood. However, the patients who experienced symptom improvement were thankful for having had the nephrostomy, despite the inconveniences. Communicating about the hazards and benefits helped patients to adjust their expectations of a nephrostomy. The study describes how nephrostomy is a burdensome intervention accompanied by a plethora of complex physical and psychosocial issues. Having a nephrostomy on a palliative indication has extensive implications for the patients, which should not be neglected or underestimated. Individual assessment of each patient, together with excellent communication regarding the procedure and outcome, is essential. Most patients had frequent contact with the healthcare system and additional support could be offered by a palliative care service.

Cultural factors affecting urban Mexican male homosexual behavior.

PubMed

Carrier, J M

1976-03-01

Some aspects of the mestizoized urban culture in Mexico are linked to male homosexuality in support of the theory that cultural factors play an important role in the kind of life styles and sex practices of males involved in homosexual behavior. The following factors are considered relevant: the sharp dichotomization of gender roles, dual categorization of females as good or bad, separate social networks maintained by males before and after marriage, proportion of unmarried males, and distribution of income. One result of the sharp dichotomization of male and female gender roles is the widely held belief that effeminate males generally prefer to play the female role rather than the male. Effeminacy and homosexuality are also linked by the belief that as a result of this role preference effeminate males are sexually interested only in masculine males with whom they play the passive sex role. The participation of masculine males in homosexual encounters is related in part to a relatively high level of sexual awareness in combination with the lack of stigmatization of the insertor sex role and in part to the restraints placed on alternative sexual outlets by available income and/or marital status. Males involved in homosexual behavior in Mexico operate in a sociocultural environment which gives rise to expectations that they should play either the insertee or insertor sex role but not both and that they should obtain ultimate sexual satisfaction with anal intercourse rather than fellatio. In spite of cultural imperatives, however, individual preferences stemming from other variables such as personality needs, sexual gratification, desires of wanted partners, and amount of involvement may override the imperatives with resulting variations in sexual behavior patterns.

There is little information on the association of sarcopenia with physical activity in elderly cardiac patients. This study determined differences in physical activity and cutoff values for physical activity according to the presence or absence of sarcopenia in elderly male cardiac patients. Sixty-seven consecutive men aged ≥65 years with cardiac disease were enrolled. We defined sarcopenia using the European Working Group on Sarcopenia in Older People algorithm. Patients were divided into the sarcopenia group (n=25) and the non-sarcopenia group (n=42). In the patients with and without sarcopenia of physical activities were evaluated to determine cutoff values of physical activity. After adjusting for patient characteristics, both the average daily number of steps (3361.43±793.23 vs. 5991.55±583.57 steps, P=0.021) and the average daily energy expenditure of physical activity (71.84±22.19 vs. 154.57±16.18kcal, P=0.009) were significantly lower in the sarcopenia versus non-sarcopenia group. Receiver-operating characteristic analysis identified a cutoff value for steps of physical activity of 3551.80steps/day for 1 week, with a sensitivity of 0.73 and 1-specificity of 0.44 and a cutoff value for energy expenditure of physical activity of 85.17kcal/day for 1 week, with a sensitivity of 0.73 and 1-specificity of 0.27. Physical activity in the male cardiac patients with sarcopenia was significantly lower than that in those without sarcopenia. The cutoff values reported here may be useful values to aid in the identification of elderly male cardiac patients with sarcopenia. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Second cancers in patients with male breast cancer: a literature review.

The risk of second malignancies among female breast cancer patients has been studied for decades. In contrast, very little is known about second primary tumors in men. Risk factors for breast cancer in men, including genetic, hormonal and environmental factors, provide parallels to the etiology of breast cancer in women. This review considers the literature related to the risk of developing a second cancer in patients with male breast cancer. A systematic review of the literature between 1966 and 2007 was conducted and acceptable articles used for analysis. All retrieved articles were screened to identify any papers that had been missed. Studies were included if they discussed the risk of subsequent malignancy in patients with male breast cancer. Patients with history of male breast cancer have an increased risk of a second ipsilateral, or contralateral breast cancer (standardized incidence ratio 30-110). The risk of subsequent contralateral breast cancer was highest in men under 50 years of age at the time of the diagnosis of the initial cancer. The data on non-breast second primary cancers is diverse. One study has suggested an increased incidence of cancers of the small intestine, prostate, rectum and pancreas, and of non-melanoma skin cancer and myeloid leukaemia. Other investigators did not find an increase in the overall risk of subsequent cancer development in men diagnosed initially with primary breast cancer. Although sarcoma, lung and esophageal cancers are well recognized complications of radiation therapy for female breast cancer, there is no evidence for the association of these cancers following radiation therapy in male breast cancer. Although the incidence of second primary cancer in patients with primary male breast cancer requires further study, male breast cancer survivors should probably undergo periodic screening for the early detection of second breast cancers and other adverse health effects.

Nurse practice issues regarding sperm banking in adolescent male cancer patients.

The impressive increase in the survival rate of childhood cancer patients has produced increased interest in quality of life issues. This research addresses nurse practice issues in determining whether the newly diagnosed adolescent male patient is offered the option of sperm banking before undergoing chemotherapy treatment. Questionnaires were distributed to nurses and nurse practitioners on 3 inpatient and outpatient units who care for adolescent male cancer patients at the time of diagnosis, during chemotherapy, and during follow-up care. Findings indicate that 96.3% of respondents agreed that all male patients undergoing cancer treatment with infertility as a potential side effect should be offered sperm banking. Respondents viewed oncologists and nurse practitioners as appropriate professionals to discuss the option. Lack of knowledge regarding sperm banking could be limiting nurses' willingness to introduce the topic, and education regarding cryopreservation may improve their knowledge and practice.

Does patient satisfaction affect patient loyalty?

PubMed

Kessler, Daniel P; Mylod, Deirdre

2011-01-01

This paper aims to investigate how patient satisfaction affects propensity to return, i.e. loyalty. Data from 678 hospitals were matched using three sources. Patient satisfaction data were obtained from Press Ganey Associates, a leading survey firm; process-based quality measures and hospital characteristics (such as ownership and teaching status) and geographic areas were obtained from the Centers for Medicare and Medicaid Services. The frequency with which end-of-life patients return to seek treatment at the same hospital was obtained from the Dartmouth Atlas. The study uses regression analysis to estimate satisfaction's effects on patient loyalty, while holding process-based quality measures and hospital and market characteristics constant. There is a statistically significant link between satisfaction and loyalty. Although satisfaction's effect overall is relatively small, contentment with certain hospitalization experience may be important. The link between satisfaction and loyalty is weaker for high-satisfaction hospitals, consistent with other studies in the marketing literature. RESEARCH LIMITATION/IMPLICATIONS: The US hospitals analyzed are not a random sample; the results are most applicable to large, non-profit teaching hospitals in competitive markets. Satisfaction ratings have business implications for healthcare providers and may be useful as a management tool for private and public purchasers. The paper is the first to show that patient satisfaction affects actual hospital choices in a large sample. Because patient satisfaction ratings are also correlated with other quality measures, the findings suggest a pathway through which individuals naturally gravitate toward higher-quality care.

Epidemiological studies show female predominance in the prevalence of non- allergic rhinitis (NAR) and local allergic rhinitis (LAR). Experimental studies show female patients with allergic rhinitis (AR) demonstrate higher levels of sensitivity to irritants and airway hyperresponsiveness than males. Bronchial asthma shows female predominance in post-puberty patients, and gender interaction with severe asthma endotypes. Fibromyalgia, chronic fatigue syndrome, migraine and chronic cough, syndromes, which are commonly related to neurokinin substance P (SP) in the literature, also show strong female predominance. Studies have demonstrated that sex hormones, primarily oestrogens, affect mast cell activation. Mast cell proteases can amplify neurogenic inflammatory responses including the release of SP. Based on human epidemiological data and animal experimental data we hypothesized that female patients have different interaction between mast cell activation and neurogenic inflammation, i.e. substance P release, resulting in a different nasal symptom profile. To test the hypothesis we performed allergen and non-specific nasal challenges in patients with seasonal allergic rhinitis (SAR) out of season and looked for gender differences in subjective and objective responses. The interaction between subjective and objective reactivity was evaluated through the comparison of subjective symptom scores, concentrations of neurokinin substance P (SP) and cellular markers in nasal lavages after low doses of nasal allergen challenges. Female allergic subjects tended to have higher substance P (SP) concentrations both before and after non-specific challenges. The difference between post-allergen and post - hypertonic saline (HTS) challenge was highly significant in female patients (p = 0.001), while insignificant in male subjects (p = 0.14). Female patients had significantly stronger burning sensation after HTS challenge than male. These data indicate difference in the

Introduction: Sleep disturbance is a frequently overlooked complication of intensive care unit (ICU) stay. Aim: To evaluate sleep quality among patients admitted to ICU and investigate environmental and non-environmental factors that affect sleep quality in ICU. Methods: Over a 22-month period, we consecutively recruited patients who spent ≥ 2 nights post-endotracheal extubation in ICU and who were orientated to time, place, and person on the day of discharge. Self-reported sleep quality, according to a modified Freedman questionnaire, which provided data on self-reported ICU sleep quality in ICU and environmental factors affecting sleep quality in the ICU, were collected. We also investigated non-environmental factors, such as severity of illness, ICU interventions, and medications that can affect sleep quality. Results: Fifty males and 50 females were recruited with a mean (± SD) age of 65.1 ± 15.2 years. APACHE II score at admission to ICU was 18.1 ± 7.5 with duration of stay 6.7 ± 6.5days. Self-reported sleep quality score at home (1 = worst; 10 = best) was 7.0 ± 2.2; this decreased to 4.0 ± 1.7 during their stay in ICU (p < 0.001). In multivariate analysis with APACHE III as severity of illness (R2 = 0.25), factors [exp(b)(95% CI), p value] which significantly affected sleep in ICU were sex [0.37(0.19-0.72), p < 0.01], age and sex interaction [1.02(1.01-1.03), p < 0.01], bedside phone [0.92(0.87-0.97), p < 0.01], prior quality of sleep at home [1.30(1.05-1.62), p = 0.02], and use of steroids [0.82(0.69-0.98), p = 0.03] during the stay in ICU. Conclusion: Reduced sleep quality is a common problem in ICU with a multifactorial etiology. Citation: Bihari S; McEvoy RD; Kim S; Woodman RJ; Bersten AD.

Patients with Congenital Adrenal Hyperplasia (CAH) owing to 21-hydroxylase deficiency and whose karyotype is 46, XX are usually assigned to the female gender. Reported herein are the long term outcomes in three patients with CAH whose karyotype is 46, XX and who were reared as males. A retrospective review of three CAH patients with a 46, XX karyotype who were reared as males was conducted. Gender assignment, clinical and biochemical data, pre and post-genitoplasty genital examinations were reviewed. Gender identity was tested by an extensive questionnaire. Gender role, sexual preference, marital status and sexual satisfaction were evaluated by interview. The three patients were genotyped for the CYP21A2 gene confirming the diagnosis of CAH. Owing to genital virilization, cultural preferences for male gender and the lack of newborn screening programs the three patients reported herein were assigned to the male gender at birth before the diagnosis of CAH was established. In adulthood the patients remained significantly virilized. Thorough psychosexual assessments in adulthood revealed well established male gender identities compatible with their male gender assignments at birth. In all three patients, gender role and behavior were consistent with male gender identity including sexual intercourse with female partners. The three patients reported herein revealed that male gender assignment to CAH patients with a 46, XX karyotype may have a successful outcome providing there is strong parental support and expert endocrine care. No standard guidelines have been published for the gender assignment of CAH patients with a 46, XX karyotype and genital ambiguity. More studies concerning gender assignment in CAH patients with a 46, XX karyotype reared as males are needed. Copyright © 2016 Elsevier Ltd. All rights reserved.

Mutations in the large GPR98 gene underlie Usher syndrome type 2C (USH2C), and all patients described to date have been female. It was speculated that GPR98 mutations cause a more severe, and eventually lethal, phenotype in males. We describe for the first time two male patients with USH2 with novel GPR98 mutations. Clinical characterization of a male patient and his affected sister revealed a typical USH2 phenotype in both. GPR98 may have been excluded from systematic investigation in previous studies, and the proportion of patients with USH2C probably underestimated. GPR98 should be considered in patients with USH2 of both sexes.

Gait analysis of young male patients diagnosed with primary bladder neck obstruction.

Primary bladder neck obstruction (PBNO) represents an inappropriate or inadequate relaxation of the bladder neck during micturition. Based on the observation of an increased rate of postural imbalances in male patients with PBNO, we hypothesized a possible role of an unbalanced biomechanics of the pelvis on urethral sphincters activity. Our aim was to identify kinematic imbalances, usually disregarded in PBNO patients, and which could eventually be involved in the etiopathogenesis of the disease. Seven male adult patients (39.6±7.1years) were recruited; in all patients, PBNO was suspected at bladder diary and uroflowmetry, and was endoscopically confirmed with urethroscopy. Participants gait was recorded with a motion capture system (BTS Spa, Italy) to obtain three-dimensional joint angles and gait parameters. Multivariate statistics based on a Principal Component model allowed to assess the similarity of patients' gait patterns with respect to control subjects. The main finding is that patients with PBNO showed significant discordance in the observations at the ankle and pelvis level. Additionally, 6/7 patients demonstrated altered trunk positions compared to normal curves. We suggest that the identified postural imbalances could represent the cause for an anomalous activation of pelvic floor muscles (hypertonia). The consequent urinary sphincters hypercontraction may be responsible for the development of voiding dysfunction in male patients with no significant morphological alterations. Results reinforced the hypothesis of an etiopathogenetic role of postural imbalances on primary bladder neck obstruction in male patients. Copyright © 2017 Elsevier Ltd. All rights reserved.

The exercise electrocardiogram is a commonly used non-invasive method for detection of electrocardiogram (ECG) changes secondary to myocardial ischemia. Studies showed the importance of the patient's motivation to reach the estimated submaximal heart rate. The purpose of this study was to test whether the patient's motivation is dependent on the investigator's sex. We included 1170 patients (in-hospital patients and out-clinic patients; 63.5% male, 36.5% female) in this study. Stress test data (stationary bicycle with gradually increasing intensity) were collected retrospectively: patient's age, sex, maximal power stage, ECG-abnormalities, angina pectoris, and attending physician's sex. Male patients achieved a higher power stage than their female counterparts (126.5+/-47.7 W vs. 89.7+/-30.4 W). When male patients were supervised by a female doctor they reached higher maximum power stages (136.6+/-53.5 W vs. 121.6+/-43.3 W; p=0,001), more often the submaximal heart rate (47.9% vs. 38.3%; p=0.02) but complained less frequent about angina pectoris (5.6% vs. 17.3%). In contrast, none of these parameters was dependent on the attending physician's sex in female patients. The attending physician's sex influences the maximum exercise ability and the incidence of complaints during bicycle stress in male patients but not in females. We would speculate that men try to impress women with physical strength and try to dissimulate physical discomfort or pain. This could possibly influence the validity of such non-invasive methods with exercise dependent detection of myocardial ischemia.

The aim of this study was to investigate the risk factors affecting long-term prognosis of autotransplantation of third molars with complete root formation in males at dental clinics. Participating dentists were requested to provide information on transplantations they had undertaken from 1 January 1990 to 31 December 2010. Data on a total of 708 teeth from 637 patients were collected. After data screening and elimination, participants of this study consisted of 183 teeth of 171 males ranging from 20 to 72 years of age (mean age, 44·8 years). The cumulative survival rate was 86·0% at the 5-year mark, 59·1% at 10 years and 28·0% at 15 years. The mean survival time was 134·5 months, as calculated by the Kaplan-Meier method. Single factor analysis using the log-rank test showed that the following factors had significant influence (P < 0·05) on survival of transplanted teeth: periodontal disease as the reason for recipient site tooth extraction, fewer than 25 present teeth and Eichner index Groups B1 to C. Cox regression analysis examined five factors: age, smoking habit, recipient site extraction caused by periodontal disease, fewer than 25 present teeth and Eichner index. This analysis showed that two of these factors were significant: fewer than 25 present teeth was 2·63 (95% CI, 1·03-6·69) and recipient site extraction caused by periodontal disease was 3·80 (95% CI, 1·61-9·01). The results of this study suggest that long-term survival of transplanted teeth in males is influenced not only by oral bacterium but also by occlusal status. © 2012 Blackwell Publishing Ltd.

The aims are to study personality characteristics of patients with memory complaints and to assess the presence of objective (OMI) versus subjective (SMI) memory impairment, the affective status, as well as potential gender differences. The patients were assessed by means of a neuropsychiatric examination and a neuropsychological test-battery. The Swedish version of the revised NEO Personality Inventory (NEO PI-R) and the Hospital Anxiety and Depression Scale (HADS) were used. The 57 patients (38 women, 19 men, mean age 56.9) differed from the Swedish normative group in three of the five personality factors: neuroticism, extraversion and agreeableness. This was mainly because of the scores of the female patients. Approximately half of the patients had OMI. No differences regarding personality factors or affective status were found between OMI and SMI patients. The female patients scored significantly higher than the male patients on symptoms of anxiety and depression. Neuroticism and symptoms of depression interacted with memory performance and gender. Our findings demonstrate the importance of applying an objective assessment of memory functions and a gender perspective when studying patients with memory complaints.

Exposure to drinking water containing as much as 500 ppm aluminum chloride for periods of 30, 60, and 90 days had no apparent effect on male reproductive processes. In an attempt to correlate enzyme activity with particular spermatogenic cell types, postnatal development of testicular enzymes was studied. Eight enzymes were selected: hyaluronidase (H), lactate dehydrogenase isoenzyme-X (LDH-X), dehydrogenases of sorbitol (SDH), α-glycerophosphate (GPDH), glucose-6-phosphate (G6PDH), malate (MDH), glyceraldehyde-3-phosphate (G3PDH), and isocitrate (ICDH). Enzyme specific activities in testicular homogenates were determined. Two types of enzyme developmental patterns were observed. One was represented by H, LDH-X, SDH, and GPDH; and the other by G6PDH, MDH, G3PDH, and ICDH. The former was characterized by a change in enzyme activities from low in newborn to high in adult while in the latter this pattern was reversed. The two complementary enzyme systems crossed each other at puberty. Prior to puberty, only spermatogonial cells are present; sperm differentiation initiated at puberty adds spermatocytes and spermatids to the testicular cell population. Male rats were exposed to borax in their diet for periods of 30 and 60 days. Concentrations of boron were 0, 500, 1000, and 2000 ppm. At the end of each experimental period, the specific activities of the selected enzymes were determined in the testis and prostate. Correlations of enzyme activity with testicular histology and androgen activities of the male accessory organs were sought. In addition, plasma FSH, LH, and testosterone levels were measured to assess pituitary-testicular interaction. Plasma and testicular boron concentrations were determined and a minimum boron concentration which induced germinal aplasia and male infertility was estimated. In both 30 and 60 day feeding studies, male rats receiving 500 ppm failed to demonstrate any significant adverse effects. In contrast, male rats receiving 100 and 2000 ppm

Smoking behaviour and its course is influenced by personality factors. Affective temperaments could allow a more specific framework of the role trait affectivity plays in this seriously harmful health-behaviour. The aim of our study was to investigate if such an association exists in an ageing population with a special emphasis on gender differences. 459 primary care patients completed the TEMPS-A, Beck Depression Inventory (BDI) and Hamilton Anxiety Rating Scale (HAM-A). Subjects were characterized according to their smoking behaviour as current, former or never smokers. Univariate analysis ANOVA and logistic regression were performed to analyse differences in the three smoking subgroups to predict smoking initiation and maintenance. Current smokers were younger and less educated than former or never smokers. Males were more likely to try tobacco during their lifetime and were more successful in cessation. Depressive, cyclothymic and irritable temperament scores showed significant differences between the three smoking subgroups. Irritable temperament was a predictor of smoking initiation in females whereas depressive temperament predicted smoking maintenance in males with a small, opposite effect of HAM-A scores independent of age, education, lifetime depression and BDI scores. Whereas smoking initiation was exclusively predicted by a higher BDI score in males, smoking maintenance was predicted by younger age and lower education in females. The cross-sectional nature of the study design may lead to selective survival bias and hinder drawing causal relationships. Affective temperaments contribute to smoking initiation and maintenance independently of age, education, and depression. The significant contribution of depressive temperament in males and irritable temperament in females may highlight the role of gender-discordant temperaments in vulnerable subgroups.

Most of the patients are affected by isolated infantile hypertrophic pyloric stenosis (IHPS) beyond the polygenic predisposition, the other factors in the multifactorial etiology are largely unknown. The main characteristic of IHPS is the robust male predominance, thus the aim of this study was to analyze birth outcomes in males and females whether they are different or not. The study samples included 241 cases with IHPS, 357 matched, and 38,151 population controls without any defect in the population-based large dataset of the Hungarian Case-Control Surveillance of Congenital Abnormalities, 1980-1996. The findings of this case-control study confirmed the well-known strong male excess (85.5%). The mean gestational age was somewhat longer and it is associated with a lower rate of preterm births. Mean birth weight did not show significant differences among the study groups, but the rate of low birthweight was higher in cases with IHPS. However, these differences were found only in males. Thus, intrauterine fetal growth restriction is characteristic only for male cases with IHPS. Our study confirmed the well-known obvious male excess of cases with IHPS, but our findings suggest some differences in birth outcomes of male and female cases. Male cases with IHPS had intrauterine fetal growth restriction while females did not. These data may indicate some differences in the pathogenesis of IHPS in males and females.

Immunophenotype of nipple adenoma in a male patient.

PubMed

Fernandez-Flores, Angel; Suarez-Peñaranda, Jose-Manuel

2011-03-01

Adenoma of the nipple is rare in men. It must be distinguished from a breast carcinoma and from Paget disease. In this sense, immunohistochemistry can be of some help. In women, for instance, immunoexpression of c-erbB-2 favors a diagnosis of Paget disease, according to some studies. Nevertheless, we have not found any studies on HER2/neu status, estrogen receptors, or progesterone receptors in nipple adenoma of male patients. We present a case of an adenoma of the nipple in a 21-year-old man in which we carried out a wide immunohistochemical study. The lesion did not express estrogen receptors, progesterone receptors, or androgen receptors. The HercepTest was negative. Smooth muscle Actin and p63 were remarked in the basal layer of the tumoral tubules, supporting the benignancy of the lesion. This case of adenoma of the nipple in a male shows an immunophenotype that is similar to the ones reported in female patients.

A strong association has been established between migraine and depression. However, this is the first study to differentiate in a large sample of migraine patients for symptom dimensions of the affective disorder spectrum. Migraine patients (n=3174) from the LUMINA (Leiden University Medical Centre Migraine Neuro-analysis Program) study and patients with current psychopathology (n=1129), past psychopathology (n=477), and healthy controls (n=561) from the NESDA (Netherlands Study of Depression and Anxiety) study, were compared for three symptom dimensions of depression and anxiety. The dimensions -lack of positive affect (depression specific); negative affect (nonspecific); and somatic arousal (anxiety specific)- were assessed by a shortened adaptation of the Mood and Anxiety Symptom Questionnaire (MASQ-D30). Within the migraine group, the association with migraine specific determinants was established. Multivariate regression analyses were conducted. Migraine patients differed significantly (p<0.001) from healthy controls for all three dimensions: Cohen's d effect sizes were 0.37 for lack of positive affect, 0.68 for negative affect, and 0.75 for somatic arousal. For the lack of positive affect and negative affect dimensions, migraine patients were predominantly similar to the past psychopathology group. For the somatic arousal dimension, migraine patients scores were more comparable with the current psychopathology group. Migraine specific determinants for high scores on all dimensions were high frequency of attacks and cutaneous allodynia during attacks. This study shows that affective symptoms in migraine patients are especially associated with the somatic arousal component. Copyright © 2015 Elsevier Inc. All rights reserved.

Background. Male hypogonadism is an endocrine disease characterized by low levels of serum testosterone and is closely related to the development of diabetes. The purpose of the present study was to observe the risk factors for hypogonadism in male patients with type 2 diabetes. Methods. A total of 213 patients with type 2 diabetes were enrolled and divided into a low total testosterone (TT) group (=75) and a normal TT group (=138). The patients' blood glucose, blood lipids, serum insulin, and sex hormones were measured. The correlations between the patients' metabolic index and sex hormone levels were analyzed. Results. Compared with the normal TT group, body mass index (BMI), fasting insulin (FINS), and HOMA insulin resistance index (HOMA-IR) levels were significantly higher, but the luteinizing hormone (LH) levels were significantly lower in the low TT group (p < 0.05). Correlation analyses found that TT was negatively correlated with BMI, waist circumference (WC), FINS, and HOMA-IR. TT was positively correlated with LH and follicle-stimulating hormone (FSH). Conclusions. Several risk factors of diabetes associated closely with hypogonadism. BMI, metabolic syndrome (MS), HOMA-IR, and LH are independent risk factors for hypogonadism in male patients with type 2 diabetes. PMID:27006953

Individuals with autism spectrum disorders (ASDs) have impairments in executive function and social cognition, with males generally being more severely affected in these areas than females. Because the dopamine D1 receptor (encoded by DRD1) is integral to the neural circuitry mediating these processes, we examined the DRD1 gene for its role in susceptibility to ASDs by performing single marker and haplotype case-control comparisons, family-based association tests, and genotype-phenotype assessments (quantitative transmission disequilibrium tests: QTDT) using three DRD1 polymorphisms, rs265981C/T, rs4532A/G, and rs686T/C. Our previous findings suggested that the dopaminergic system may be more integrally involved in families with affected males only than in other families. We therefore restricted our study to families with two or more affected males (N = 112). There was over-transmission of rs265981-C and rs4532-A in these families (P = 0.040, P = 0.038), with haplotype TDT analysis showing over-transmission of the C-A-T haplotype (P = 0.022) from mothers to affected sons (P = 0.013). In addition, haplotype case-control comparisons revealed an increase of this putative risk haplotype in affected individuals relative to a comparison group (P = 0.004). QTDT analyses showed associations of the rs265981-C, rs4532-A, rs686-T alleles, and the C-A-T haplotype with more severe problems in social interaction, greater difficulties with nonverbal communication and increased stereotypies compared to individuals with other haplotypes. Preferential haplotype transmission of markers at the DRD1 locus and an increased frequency of a specific haplotype support the DRD1 gene as a risk gene for core symptoms of ASD in families having only affected males.

Background: Several studies have demonstrated an association between androgenetic alopecia (AGA) and cardiovascular disease. Still controversies exist regarding the association. Are they truly associated? Objective: The purpose of the present study was to assess the prevalence of AGA and establish its association in young (<45 years) Asian Indian Gujarati male patients having coronary artery disease (CAD). Materials and Methods: Case-control prospective multicentric study was carried out on 424 men. Case group consisted of 212 male subjects having CAD (Group 1) and another 212, either sibling or first degree male relative of the case subjects (having no evidence of CAD) were considered as the control group (Group 2). Age, total cholesterol, incidence of diabetes mellitus, and hypertension were similar in both groups. The degree of alopecia was assessed using the Norwood-Hamilton scale for men. Statistical analysis was performed using Chi-square test. Results: AGA was found in 80 (37.73%) young CAD patients (Group 1), whereas 44 (20.7%) of patients had alopecia in the control group (Group 2). There was statistically significant association between male AGA and CAD (P = 0.001). Odds ratio was 2.70 (95% confidence interval [CI], 1.72 ± 4.26). Statistically significant association was found between high grade baldness (Grades IV-VII) and CAD in young men (P < 0.05). Odds ratio = 2.36 (95% CI, 1.108 ± 5.033). There is statistically significant association of AGA in young Asian Gujarati male with CAD and the prevalence of AGA in young CAD patient is 37.73%. Conclusion: This study implies early onset AGA in male is independently associated with CAD, though mechanisms need to be investigated. PMID:25114445

A retrospective study. The aim of this study was to assess the changes in sexual activities in male patients surgically treated for ankylosing spondylitis (AS)-induced kyphosis and the correlation between these changes and spinal sagittal realignment. Sexual function may be affected by AS. However, little is known about the effect of spinal surgery on the sexual activity of patients with AS-induced kyphosis. Data of 45 male patients who had been surgically treated for AS-induced kyphosis were retrospectively reviewed. Changes in sexual activity were evaluated by the international index of erectile function (IIEF), frequency of sexual activity, and time point at which sexual activity began postoperatively. We compared the above-mentioned parameters before and 24 months postoperatively and analyzed the correlation of the changes in the IIEF with the changes in radiological characteristics. Each domain of the IIEF and the total IIEF were increased postoperatively. Improved sexual function was correlated with changes in spinal sagittal characteristics, among which lumbar lordosis (LL) and the chin-brow vertical angle (CBVA) were the most significant causes (P < 0.05). Most patients (71.1%) resumed their sexual activity 5 to 12 weeks after surgery. At the 24-month follow-up, the frequency of patients' sexual activity was higher than that before surgery (P < 0.05). Surgical correction of spinal deformity may improve sexual function and increase the frequency of sexual activity in men with AS. Spinal sagittal realignment and pelvic rotation may be correlated with improvement of sexual function. 4.

Group-housed male mice exhibit aggressive behaviour towards their cage mates and form a social hierarchy. Here, we describe how social hierarchy in standard group-housed conditions affects behaviour and gene expression in male mice. Four male C57BL/6 mice were kept in each cage used in the study, and the social hierarchy was determined from observation of video recordings of aggressive behaviour. After formation of a social hierarchy, the behaviour and hippocampal gene expression were analysed in the mice. Higher anxiety- and depression-like behaviours and elevated gene expression of hypothalamic corticotropin-releasing hormone and hippocampal serotonin receptor subtypes were observed in subordinate mice compared with those of dominant mice. These differences were alleviated by orally administering fluoxetine, which is an antidepressant of the selective serotonin reuptake inhibitor class. We concluded that hierarchy in the home cage affects behaviour and gene expression in male mice, resulting in anxiety- and depression-like behaviours being regulated differently in dominant and subordinate mice.

The aim of this study was to evaluate neuroendocrine activation during stress in patients with recently diagnosed multiple sclerosis before starting the immunomodulatory therapy (EDSS score≤2.0). We verified the hypothesis that certain cognitive and affective dysfunction is present already at this early stage of the disease. The sample consisted of 38 subjects, which involved patients who were recently diagnosed multiple sclerosis and age- and sex-matched healthy volunteers. Stroop test served as mental stress model enabling measurement of cognitive performance. Present results showed increased state anxiety, depression scores and poorer performance in the Stroop test in the group of patients compared to healthy subjects. The cognitive dysfunction was particularly evident in male patients with simultaneously decreased concentrations of the brain-derived neurotrophic factor (BDNF) in plasma. The patients at this stage of the disease have not yet developed the hyperactivity of the hypothalamic-pituitary-adrenocortical axis. They showed normal levels of plasma copeptin and reduced aldosterone response to mental stress test in women only. Concentrations of plasma copeptin were higher in men compared to women. Very early stages of multiple sclerosis are accompanied by disturbances in psychological well-being, mild cognitive dysfunction and decreased plasma concentrations of BDNF, particularly in male patients.

To compare the intensity and the profile of psychotic symptoms and the characteristics of parental bonding of male schizophrenia patients with a history of homicide and those without a history of violent behaviour. Clinical question - We hypothesized more intense psychotic symptoms, especially positive symptoms as signs of a more severe psychopathology in the background of homicidal behaviour. We also hypothesized a more negatively perceived pattern (less Care more Overprotection) of parental bonding in the case of homicidal schizophrenia patients than in non-violent patients and non-violent healthy controls. Symptom severity and symptom profiles were assessed with the Positive and Negative Syndrome Scale in a group of male schizophrenia patients (n=22) with the history of committed or attempted homicide, and another group (n=19) of male schizophrenia patients without a history of violent behaviour. Care- and Overprotection were assessed using the Parental Bonding Instrument (PBI) in a third group of non-violent healthy controls (n=20), too. Positive, negative and general psychopathology symptoms in the homicidal schizophrenia group were significantly (p<0.005) more severe than in the non-violent schizophrenia group. Non-violent schizophrenia patients scored lower on Care and higher on Overprotection than violent patients and healthy controls. Homicidal schizophrenia patients showed a pattern similar to the one in the healthy control group. It seems imperative to register intense positive psychotic symptoms as predictive markers for later violent behaviour. In the subgroup of male homicidal schizophrenia patients negatively experienced parental bonding does not appear to be major contributing factor to later homicidal behaviour.

[Do physicians' gender and workload affect patients?].

PubMed

Finnvold, Jon Erik

2008-10-23

The article discusses the effect of general practitioners' gender and workload on patients' experience with consultation time, waiting hours, use of out-of-hours services and planned health visits. Data were retrieved from the 2003 version of Statistics Norway's household panel study (5000 persons) and the National Insurance administration's register of regular general practitioners. Health condition was the most important factor related to patient experiences. A high workload was neither associated with more frequent use of out-of-hours services nor satisfaction with time spent in consultation. These results apply to physicians of both genders. Patients who used a female physician with a large workload had to wait longer for an appointment and more often reported dissatisfaction with the waiting time; this was not the case for male physicians. However, male physicians with a low workload had shorter waiting times. Patients who use practitioners with a high workload may have chosen their doctor more deliberately than others, which may be an explanation for few negative outcomes for physicians with a high workload. It is unlikely that these physicians would be as popular if the patients had fewer appointments, shorter consultations or more often had to use the out-of-hours services. Longer waiting time for appointments with female doctors may be related to more part time work, and the fact that female physicians more often are engaged in group practices.

Primary biliary cirrhosis (PBC), which predominantly affects women, has been associated with various autoimmune diseases. Although hypothyroidism accompanying PBC is well documented, the concomitance of PBC and hyperthyroidism is rare. Herein, we report the case of a 62-year-old man who was diagnosed with PBC several years after the development of Graves' disease. This is the first case of a male patient developing PBC with Graves' disease. Both serum alanine aminotransferase levels and serum thyroid hormone levels were normalized after the administration of thiamazole for Graves' disease. However, the cholestatic liver enzyme abnormalities continued, indicating that the PBC was actualized by the administration of thiamazole. After starting ursodeoxycholic acid treatment, cholestatic liver enzyme abnormalities improved. Taken together, when a cholestatic pattern of liver enzymes is observed during follow-up for Graves' disease, an association between Graves' disease and PBC should be considered as a differential diagnosis.

Prior studies attempted to explore the association between schizophrenia and hepatitis C virus (HCV). However, their conclusions were inconsistent. This study aimed to examine the association of schizophrenia with HCV using a population-based dataset in Taiwan. There were 6097 patients with schizophrenia and 6097 sex- and age-matched comparison patients without schizophrenia included in this study. We defined the dependent variable of interest as whether or not a patient had received a diagnosis of HCV. We found that of the sampled patients, 2.1% of patients with schizophrenia and 1.4% of comparison patients had concurrent HCV. We further found that schizophrenia was not significantly associated with concurrent HCV after adjusting for sex, age, urbanization level, geographic region, monthly income, and drug abuse. However, of the sampled male patients, the adjusted odds of concurrent hepatitis C for patients with schizophrenia were 1.72-times higher than the odds of concurrent HCV among comparison patients. We failed to observe this association among female sampled patients. We concluded that schizophrenia was not significantly associated with concurrent HCV. However, of the sampled male patients, the risk of concurrent HCV among patients with schizophrenia was higher than comparison patients. Copyright © 2017 Elsevier B.V. All rights reserved.

Genetic causes of male infertility.

2014-05-01

Male infertility, affecting around half of the couples with a problem to get pregnant, is a very heterogeneous condition. Part of patients are having a defect in spermatogenesis of which the underlying causes (including genetic ones) remain largely unknown. The only genetic tests routinely used in the diagnosis of male infertility are the analyses for the presence of Yq microdeletions and/or chromosomal abnormalities. Various other single gene or polygenic defects have been proposed to be involved in male fertility. Yet, their causative effect often remains to be proven. The recent evolution in the development of whole genome-based techniques may help in clarifying the role of genes and other genetic factors involved in spermatogenesis and spermatogenesis defects.

Pigmented mammary tumours are rare. Herein, we report the third case of primary pigmented breast adenocarcinoma in a male patient with clinical mimicking of nodular melanoma of the nipple. A male patient presented with a pigmented nodule of the right nipple. Histological examination of the lesion showed dermal and subcutaneous adenocarcinomatous proliferation. The perilesional stroma contained melanin both inside and outside macrophages, leading us to conclude on primary pigmented breast adenocarcinoma clinically mimicking nodular melanoma of the nipple. Local production of melanin by neoplastic cells in the mammary carcinoma was postulated as the cause of hyperpigmentation of the tumour. Other possible causes are transfer of melanin from overlying melanocytes of the pigmented areolar epidermis to the underlying neoplastic cells, or melanin synthesis by intratumoral melanocytes migrating from the epidermis (which strikes us as the most convincing interpretation for the reported case). Breast adenocarcinoma is a rare tumour in men and may present clinically as a pigmented lesion of the nipple, resulting in the problem of differential diagnosis with primary or metastasised nodular melanoma.

BACKGROUND: The number of nonsurgical aesthetic procedures performed in men is growing rapidly. However, there are limited data on treatment principles and goals for the male aesthetic patient.

OBJECTIVE: To review the objective data available on male aging and aesthetics and to synthesize with expert opinion on treatment considerations specific to male patients.

METHODS: Expert advisors met to discuss anatomical differences in male versus female facial anatomy related to aging, facial treatment preferences in aesthetically oriented men, and current dosing data for facial injectable treatments in male versus female patients.

RESULTS: Symmetry, averageness, sexual dimorphism, and youthfulness are generally accepted as factors that contribute to the perception of attractiveness. There are differences between men and women in facial anatomy, concepts of attractiveness in the context of masculinity and femininity, and treatment objectives. A communication gap exists for men, as evidenced by the lack of information available online or by word of mouth about injectable treatments.

CONCLUSIONS: Approaches to aesthetic consultation and treatment should differ between men and women based on the fundamental dissimilarities between the sexes. Educating men about available aesthetic treatments and about the safety and side effects associated with each treatment, as well as addressing concerns about their treatment results looking natural, are key considerations.

It has been demonstrated that glyphosate-based herbicides are toxic to animals. In the present study, reactive oxygen species (ROS) generation, antioxidant capacity against peroxyl radicals (ACAP), and lipid peroxidation (LPO), as well as the activity and expression of the acetylcholinesterase (AChE) enzyme, were evaluated in Danio rerio males exposed to 5 or 10 mg/L of glyphosate for 24 and 96 h. An increase in ACAP in gills after 24 h was observed in the animals exposed to 5 mg/L of glyphosate. A decrease in LPO was observed in brain tissue of animals exposed to 10 mg/L after 24 h, while an increase was observed in muscle after 96 h. No significant alterations were observed in ROS generation. AChE activity was not altered in muscles or brains of animals exposed to either glyphosate concentration for 24 or 96 h. However, gene expression of this enzyme in the brain was reduced after 24 h and was enhanced in both brain and muscle tissues after 96 h. Thus, contrary to previous findings that had attributed the imbalance in the oxidative state of animals exposed to glyphosate-based herbicides to surfactants and other inert compounds, the present study demonstrated that glyphosate per se promotes this same effect in zebrafish males. Although glyphosate concentrations did not alter AChE activity, this study demonstrated for the first time that this molecule affects ache expression in male zebrafish D. rerio.

However, it is unknown whether the smoking behavior of the patients is similar in all schizophrenia subtypes, as well as which is the relationship between smoking initiation and disease onset. Four hundred six patients with DSM-IV schizophrenia were interviewed to determine the smoking status in relationship to gender and schizophrenic subtype, and to other factors that could affect or be affected by smoking. The frequency of smoking among patients (58%) was significantly greater than in subjects from the general population (42%) (P =.000005). Male patients smoked significantly more frequently (70%) than the corresponding control subjects (50%) (P =.000006), whereas the difference failed to reach significance between female patients (41%) and control subjects (32%). Among male patients, the number of smokers was significantly greater than in the controls in the paranoid (77%), undifferentiated (72%), and residual (78%) subtypes, whereas there was no significant difference in the disorganized (44%) and catatonic (22%) subtypes. The findings show that the frequency of smoking in schizophrenia patients increases with increasing positive symptoms and decreases with increasing negative symptoms. Male and female smoking patients consumed approximately 10 cigarettes per day more than the corresponding control subjects (P <.000001). In 86% of the patients, smoking initiation occurred before the disease onset. Among patients who smoked, smoking initiation and disease onset occurred at age 18.7 +/- 4.4 and 24.1 +/- 6.1 years, respectively (P <.000001). It appears that smoking in schizophrenia is influenced by gender and subtype. However, the nature of this association remains uncertain because in the vast majority of the patients smoking initiation occurs earlier than the disease onset. Copyright 2001 by W.B.

Factors affecting aggressive behaviour of spawning migratory males towards mature male parr in masu salmon Oncorhynchus masou.

PubMed

Watanabe, M; Maekawa, K

2010-07-01

This study examined whether dominant migratory males (adopting fighter tactics) of the masu salmon Oncorhynchus masou would more aggressively attack large mature male parr (adopting sneaker tactics) as large mature male parr are expected to have the potential to cause a greater decrease in fertilization success. The frequency of aggressive behaviour was not related to the body size of males, and it increased with the frequency of interactions with mature male parr. The fertilization success of mature male parr was much lower than migratory males, and no relationship was observed between fertilization success and aggressive behaviour. The low fertilization success of mature male parr, despite infrequent aggressive behaviour by migratory males, indicates that there might be little benefit for migratory males to attack mature male parr more aggressively according to their body size.

Communicating under medical patriarchy: gendered doctor-patient communication between female patients with overactive bladder and male urologists in Hong Kong.

Gender differences between patients and doctors markedly influence the quality of communication in treatment processes. Previous studies have shown that communication between patients and doctors of the same gender is usually more satisfactory, particularly for female patients. However, in Hong Kong, where urology is a male-dominated specialty, female patients typically require medical care from male doctors for diseases such as overactive bladder (OAB). The literature about gender-related doctor-patient communication predominantly involves people in non-Chinese communities, with few studies conducted with Chinese populations. However, the differences between Western and Chinese cultures are expected to result in different treatment and communication experiences. Furthermore, OAB has received little attention in many Chinese communities; few studies in the literature address the communication quality between OAB patients and their urologists in Chinese communities, particularly regarding female OAB patients' experiences when seeking treatment from male urologists. This study, therefore, investigated the doctor-patient communication between female OAB patients and male urologists in Hong Kong. This study adopted a qualitative research approach by conducting semistructured interviews with 30 female OAB patients on an individual basis from April 2012 to July 2012. The participants were purposively sampled from a patient self-help group for OAB patients in Hong Kong. The participants' communication experiences with male urologists were unpleasant. Embarrassment, feelings of not being treated seriously, not being understood, and not being given the autonomy to choose treatment approaches prevailed among the participants. Furthermore, the perceived lack of empathy from their urologists made the participants' communication experiences unpleasant. The gender and power differential between the participants and their urologists, which was contributed by the social and

To evaluate the influence of an hydrophilic statin, pravastatin, on adrenal and testicular steroidogenesis and spermatogenesis, eight male hypercholesterolemic patients were studied. All patients observed a hypocholesterolemic diet and received placebo for 4 weeks followed by pravastatin (20 mg/die) for 6 months. Before, during (4th-5th week) and at the end (23th-24th week) of active treatment, CRH (1 microgram i.v.), ACTH (Synacthen 250 micrograms i.v.) and human CG (HCG 3000 IU i.m.) tests were performed in addition to semen analysis. Pravastatin significantly reduced total cholesterol (20.3%), calculated LDL-cholesterol (24.6%) and apolipoprotein B (10.5%, increased apolipoprotein A1 (16.1%) and did not influence plasma HDL-cholesterol and triglycerides. Basal plasma cortisol, aldosterone, androstenedione, testosterone and oestradiol did not change under active treatment. Pravastatin administration affected neither adrenal hormone responses to CRH and ACTH or testicular response to HCG nor spermatogenesis in respect of motility, morphology and sperm count. In conclusion, long-term pravastatin treatment, at doses effective in improving lipid profile, did not influence testicular reproductive and endocrine function and did not interfere with basal and stimulated adrenal activity of male hypercholesterolemic patients.

It has been argued that borderline personality disorder (BPD) is related to an enhanced affective reactivity. According to findings from research based on self-report, individuals with BPD develop and feel more negative and less positive affect than healthy individuals. Implicit affectivity, which can be measured using indirect assessment methods, relates to processes of the impulsive, intuitive system. In the present study, implicit and explicit affectivity was examined in patients suffering from BPD compared to healthy persons. Thirty-five women with BPD and 35 healthy women participated in the study. Implicit affectivity was assessed using the Implicit Positive and Negative Affect Test (IPANAT). Measures of explicit state and trait affectivity were also administered. BPD women had lower explicit positive state and trait affect scores and higher negative state and trait affect scores than healthy women. They had also lower implicit positive affect but they did not differ from healthy women regarding implicit negative affect. Total number of comorbid disorders was correlated with both implicit positive and implicit negative affect. According to our data, BPD patients exhibit reduced implicit positive affect as well as reduced explicit positive affect compared to healthy persons. According to our IPANAT data, BPD patients are characterized by a normal disposition to develop negative affective reactions which is in line with a number of findings from psycho-physiological research on BPD. Self-reports of negative affectivity in BPD could be biased by negative distortion.

Duchenne and Becker muscular dystrophy are X-linked neuromuscular disorders characterized by progressive muscle degeneration. Despite the involvement of multiple systems, secondary conditions among affected males have not been comprehensively described. Two hundred nine caregivers of affected males (aged 3-31 years) identified by the Muscular Dystrophy Surveillance, Tracking, and Research Network completed a mailed survey that included questions about secondary conditions impacting multiple body functions. The 5 most commonly reported conditions in males with Duchenne were cognitive deficits (38.4%), constipation (31.7%), anxiety (29.3%), depression (27.4%), and obesity (19.5%). Higher frequencies of anxiety, depression, and kidney stones were found among nonambulatory males compared to ambulatory males. Attention-deficit hyperactivity disorder (ADHD) was more common in ambulatory than nonambulatory males. These data support clinical care recommendations for monitoring of patients with Duchenne or Becker muscular dystrophy by a multidisciplinary team to prevent and treat conditions that may be secondary to the diagnosis.

Background Colour signals are widely used in intraspecific communication and often linked to individual fitness. The development of some pigment-based (e.g. carotenoids) colours is often environment-dependent and costly for the signaller, however, for structural colours (e.g. ultraviolet [UV]) this topic is poorly understood, especially in terrestrial ectothermic vertebrates. Methodology/Principal Findings In a factorial experiment, we studied how available energy and time at elevated body temperature affects the annual expression of the nuptial throat colour patch in male European green lizards (Lacerta viridis) after hibernation and before mating season. In this species, there is a female preference for males with high throat UV reflectance, and males with high UV reflectance are more likely to win fights. We found that (i) while food shortage decreased lizards' body condition, it did not affect colour development, and (ii) the available time for maintaining high body temperature affected the development of UV colour without affecting body condition or other colour traits. Conclusions/Significance Our results demonstrate that the expression of a sexually selected structural colour signal depends on the time at elevated body temperature affecting physiological performance but not on available energy gained from food per se in an ectothermic vertebrate. We suggest that the effect of high ambient temperature on UV colour in male L. viridis makes it an honest signal, because success in acquiring thermally favourable territories and/or effective behavioural thermoregulation can both be linked to individual quality.

Hospital-based HIV/HSV-2 seroprevalence among male patients with anal disease in Korea: cross sectional study

PubMed Central

2014-01-01

Background This study aimed to identify the characteristics of HIV and herpes simplex virus (HSV)-2 seroprevalence in male patients with anal disease. Methods HIV seroprevalence was estimated for different age groups of male patients with anal disease who were treated at Songdo colorectal hospital in Korea between 2001 and 2011. HIV seroprevalence of patients with anal disease was compared with that of patients with nonanal disease for each year from 2007 to 2011. HSV-2 antibody tests were conducted on 2,038 HIV-tested male patients with anal disease in 2009. Results For 11 years from 2001, HIV seroprevalence differed significantly by age group (P < 0.001) and was highest in the group aged <20 years. From 2007 to 2011, HIV seroprevalence in patients with anal disease was 7.6/10,000–13.3/10,000 and that in patients with nonanal disease was 0–0.9/10,000. HSV-2 seroprevalence among patients with anal disease was 24.0%, and only one patient with HIV and HSV-2 was observed. Conclusions HIV seroprevalencein male patients with anal disease was significantly higher than that for other diseases. HSV-2 seroprevalence was similar to that in the general male population. Implementation of the current HIV surveillance system for male patients at colorectal hospitals is necessary to help prevent HIV transmission. PMID:24444046

A high frequency of hypogonadism has been reported in male patients with advanced cancer. The current study was performed to evaluate the association between low testosterone levels, symptom burden, and survival in male patients with cancer. Of 131 consecutive male patients with cancer, 119 (91%) had an endocrine evaluation of total (TT), free (FT), and bioavailable testosterone (BT); high-sensitivity C-reactive protein (CRP); vitamin B12; thyroid-stimulating hormone; 25-hydroxy vitamin D; and cortisol levels when presenting with symptoms of fatigue and/or anorexia-cachexia. Symptoms were evaluated by the Edmonton Symptom Assessment Scale. The authors examined the correlation using the Spearman test and survival with the log-rank test and Cox regression analysis. The median age of the patients was 64 years; the majority of patients were white (85 patients; 71%). The median TT level was 209 ng/dL (normal: ≥ 200 ng/dL), the median FT was 4.4 ng/dL (normal: ≥ 9 ng/dL), and the median BT was 22.0 ng/dL (normal: ≥ 61 ng/dL). Low TT, FT, and BT values were all associated with worse fatigue (P ≤ .04), poor Eastern Cooperative Oncology Group performance status (P ≤ .05), weight loss (P ≤ .01), and opioid use (P ≤ .005). Low TT and FT were associated with increased anxiety (P ≤ .04), a decreased feeling of well-being (P ≤ .04), and increased dyspnea (P ≤ .05), whereas low BT was only found to be associated with anorexia (P = .05). Decreased TT, FT, and BT values were all found to be significantly associated with elevated CRP and low albumin and hemoglobin. On multivariate analysis, decreased survival was associated with low TT (hazards ratio [HR], 1.66; P = .034), declining Eastern Cooperative Oncology Group performance status (HR, 1.55; P = .004), high CRP (HR, 3.28; P < .001), and decreased albumin (HR, 2.52; P < .001). In male patients with cancer, low testosterone levels were associated with systemic inflammation, weight loss, increased

The DNA mismatch repair (MMR) gene MutL homolog 1 ( MLH1 ) is critical for the maintenance of genomic integrity. Methylation of the MLH1 gene promoter was identified as a prognostic marker for numerous types of cancer including glioblastoma, colorectal, ovarian and gastric cancer. The present study aimed to determine whether MLH1 promoter methylation was associated with survival in male patients with esophageal squamous cell carcinoma (ESCC). Formalin-fixed, paraffin-embedded ESCC tissues were collected from 87 male patients. MLH1 promoter methylation was assessed using the methylation-specific polymerase chain reaction approach. Kaplan-Meier survival curves and log-rank tests were used to evaluate the association between MLH1 promoter methylation and overall survival (OS) in patients with ESCC. Cox regression analysis was used to obtain crude and multivariate hazard ratios (HR), and 95% confidence intervals (CI). The present study revealed that MLH1 promoter methylation was observed in 53/87 (60.9%) of male patients with ESCC. Kaplan-Meier survival analysis demonstrated that MLH1 promoter hypermethylation was significantly associated with poorer prognosis in patients with ESCC (P=0.048). Multivariate survival analysis revealed that MLH1 promoter hypermethylation was an independent predictor of poor OS in male patients with ESCC (HR=1.716; 95% CI=1.008-2.921). Therefore, MLH1 promoter hypermethylation may be a predictor of prognosis in male patients with ESCC.

Carbamazepine (CBZ) is an anti-epileptic drug that acts on Leydig cells, affecting steroidogenesis and causes fetal malformation. The aim of this study was to investigate the effects of CBZ on male sexual maturation and other male parameters. Rat dams were treated with CBZ during pregnancy and breastfeeding. The anogenital distance (AGD) and the anogenital index (AGI) were obtained. Testicular descent and preputial separation were also evaluated. The offspring was euthanized at PND 41 and 63. The accessory glands were weighed and the testes were collected for histopathological, morphometric and sterological analyses. The numerical density of Leydig cells and hormone dosage were obtained. CBZ caused an increase of AGI and a delay of testicular descent and of preputial separation. CBZ also caused a decrease of testosterone level and of sperm count and an increase of abnormal sperm. These results indicate that CBZ delays puberty onset and affects steroidogenesis and sperm quality. Copyright © 2013 Elsevier Inc. All rights reserved.

We investigated the influence of anger processing on cognitive control in male schizophrenia patients presenting violent behaviors. We recruited 23 patients without and 24 patients with (SCZ+V) a history of violent behaviors, as well as 22 healthy non-violent men. Participants were administered an affective (angry-neutral faces) Go/NoGo task while undergoing functional magnetic resonance imaging. We found a reduced activation in the dorsolateral prefrontal cortex in SCZ+V patients specifically when inhibiting a response while viewing angry faces. These results show an inability of SCZ+V to recruit a core region of the (inhibitory) cognitive control network in the context of anger. Copyright © 2017 Elsevier B.V. All rights reserved.

A cognitive-perceptual model of symptom perception in males and females: the roles of negative affect, selective attention, health anxiety and psychological job demands.

Kolk et al.'s model of symptom perception underlines the effects of trait negative affect, selective attention and external stressors. The current study tested this model in 263 males and 498 females from an occupational sample. Trait negative affect was associated with symptom reporting in females only, and selective attention and psychological job demands were associated with symptom reporting in both genders. Health anxiety was associated with symptom reporting in males only. Future studies might consider the inclusion of selective attention, which was more strongly associated with symptom reporting than negative affect. Psychological job demands appear to influence symptom reporting in both males and females.

Anabolic androgenic steroids differentially affect social behaviors in adolescent and adult male Syrian hamsters

Anabolic androgenic steroids (AAS) are synthetic derivatives of testosterone used by over half a million adolescents in the United States for their tissue-building potency and performance-enhancing effects. AAS also affect behavior, including reports of heightened aggression and changes in sexual libido. The expression of sexual and aggressive behaviors is a function of complex interactions among hormones, social context, and the brain, which is extensively remodeled during adolescence. Thus, AAS may have different consequences on behavior during adolescence and adulthood. Using a rodent model, these studies directly compared the effects of AAS on the expression of male sexual and aggressive behaviors in adolescents and adults. Male Syrian hamsters were injected daily for 14 days with either vehicle or an AAS cocktail containing testosterone cypionate (2 mg/kg), nandrolone decanoate (2 mg/kg), and boldenone undecylenate (1 mg/kg), either during adolescence (27–41 days of age) or in adulthood (63–77 days of age). The day after the last injection, males were tested for either sexual behavior with a receptive female or agonistic behavior with a male intruder. Adolescent males treated with AAS showed significant increases in sexual and aggressive behaviors relative to vehicle-treated adolescents. In contrast, AAS-treated adults showed significantly lower levels of sexual behavior compared with vehicle-treated adults and did not show heightened aggression. Thus, adolescents, but not adults, displayed significantly higher behavioral responses to AAS, suggesting that the still-developing adolescent brain is more vulnerable than the adult brain to the adverse consequences of AAS on the nervous system and behavior.

Lactotroph adenomas (LA) are the most frequently encountered pituitary tumors. Although more frequently observed in women, LAs in men were recently included in a more aggressive category regardless of histological grading, by the WHO. We aimed to perform a rigorous retrospective review of a single center's pre-operative evaluation, patient characteristics and outcomes of male LAs patients requiring pituitary surgery. A retrospective review, over 11 years, of patients who underwent resection of a pituitary adenoma at a single center was conducted. Predictors of persistent disease in male LAs patients along with a comparison to predictors of silent corticotroph adenomas (SCAs) patients who also underwent surgery at the center was also conducted. Thirty-one male patients with LAs were identified. When compared to SCAs patients, LAs male patients were younger (41 vs. 50 years of age, p = 0.01). Men with LAs had more invasive tumors (75% vs. 44.7% p = 0.02). More LAs in men had residual tumor after surgery than patients with SCA (92.6% vs. 42.1%, p < 0.001). Male patients with LAs and patients with SCA had similar rates of requiring additional surgery (28.9% vs. 24.1%, p = NS) and radiation therapy (18.4% vs. 19.4%, p = NS). High rates of DA resistance, invasive tumors and postoperative residual disease in male patients with LA who required surgery are shown. Surgery improved optic chiasm compression, PRL level and central hypogonadism but, not surprisingly, failed to normalize other pituitary hormones and/or eliminate need for DA therapy.

To study the potentially avoidable decision-making delay in acute myocardial infarction (AMI) adults male with different psychological characteristics a nationwide multicentre study was conducted in Italy by the 118 Coronary Care Units (CCUs). 929 AMI patients consecutively presented to the CCU in a conscious condition less than two hours, 2-6 hours, 6-12 hours, and more than 12 hours after symptom onset and completing the Disease Distress Questionnaire (DDQ) were enrolled in a multicentre case-control study. The DDQ collects information regarding the decision time to seek help, and includes a set of items assessing psychological factors and pain-related symptoms. The relationship between the perceived threat and the delay due to decision-making was evaluated by means of a multivariate model using LISREL 8 structural equation modelling. The delay significantly correlated with perceived threat, which was mainly related to somatic awareness. It was only slightly related to pain and was not associated with any of the other variables. Perceived threat was also related to psychological upset, fear and health worries, the first of which was considerably influenced by emotional instability. Somatic awareness is the main dimension affecting perceived threat, but subjective pain intensity affects the delay both directly and indirectly. The core of the model is the relationship between perceived threat and the delay due to decision-making. The importance of subjective pain intensity is well documented, but it is still not clear how subjective and objective pain interact.

To evaluate a training intervention for general practice-based doctors and nurses in terms of the identification, documentation, and referral of male patients experiencing or perpetrating domestic violence and abuse (DVA) in four general practices in the south west of England. Research suggests that male victims and perpetrators of DVA present to primary care clinicians to seek support for their experiences. We know that the response of primary care clinicians to women patients experiencing DVA improves from training and the establishment of referral pathways to specialist DVA services. The intervention consisted of a 2-h practice-based training. Outcome measures included: a pre-post, self-reported survey of staff practice; disclosures of DVA as documented in medical records pre-post (six months) intervention; semi-structured interviews with clinicians; and practice-level contact data collected by DVA specialist agencies. Results show a significant increase in clinicians' self-reported preparedness to meet the needs of male patients experiencing or perpetrating DVA. There was a small increase in male patients identified within the medical records (6 pre- to 17 post-intervention) but only five of those patients made contact with a specialist DVA agency identified within the referral pathway. The training increased clinicians' confidence in responding to male patients affected by DVA. The increase in recorded identification of DVA male patients experiencing or perpetrating DVA was small and contact of those patients with a specialist DVA support service was negligible. We need to better understand male help seeking in relation to DVA, further develop interventions to increase identification of male patients experiencing or perpetrating DVA behaviours, and facilitate access to support services.

We sought to determine whether patient-provider gender concordance influences the detection and care of depression and comorbid anxiety and substance use in patients with major depression Cross-sectional analyses of baseline patient survey data linked with provider data were performed. Data based on routine primary care visits in clinics from a variety of health systems serving diverse patient populations across the United States. Participants all had major depression. Depression care was examined in the Quality Improvement for Depression (QID) Collaboration sample (n patients = 1,428, n providers = 389). In a subanalysis of data solely from 714 patients and 157 providers from Partners-In-Care, one of the projects participating in QID, we also examined detection of anxiety disorder and alcohol or drug problems. Rates of detection and care of mental health problems in primary care were low even among patients with major depression. Except for anxiety counseling in female patients, patient-provider gender concordance did not improve care as hypothesized. However, female providers were more likely to counsel on anxiety and less likely to counsel on alcohol or drug use than male providers. Female patients were less likely to be counseled on alcohol or drug use compared with male patients. Detection and care of mental health and substance use problems for patients with major depression is not influenced by patient-provider gender concordance. However, depressed female patients may have greater unmet needs for alcohol and drug use counseling than their male counterparts.

The evolution of exaggerated vocal signals in anuran species is an important topic. Males and females have both evolved the ability to discriminate communication sounds. However, the nature of sexual dimorphism in cognition and sensory discrimination and in the evolution and limitation of sexual signal exaggeration remain relatively unexplored. In the present study, we used male calls of varied complexity in the serrate-legged small treefrog, Kurixalus odontotarsus , as probes to investigate how both sexes respond to variations in call complexity and how sex differences in signal discrimination play a role in the evolution of sexual signal exaggeration. The compound calls of male K. odontotarsus consist of a series of one or more harmonic notes (A notes) which may be followed by one or more short broadband notes (B notes). Male playback experiments and female phonotaxis tests showed that increasing the number of A notes in stimulus calls elicits increased numbers of response calls by males and increases the attractiveness of the stimulus calls to females. The addition of B notes, however, reduces male calling responses. Moreover, call stimuli which contain only B notes suppress spontaneous male calling responses. Phonotaxis experiments show that females prefer calls with greater numbers of A notes and calls containing both A notes and B notes, but do not prefer calls with only B notes. Male-male competition and female choice appear to have played different roles in the evolution and limitation of signal complexity in K. odontotarsus . These results provide new insights into how exaggerated compound signals evolve and how signal complexity may be limited in anurans.

Improved targeted therapies for rheumatic diseases were developed recently resulting in a better prognosis for affected patients. Nowadays, patients are living longer and with improved quality of life, including fertility potential. These patients are affected by impaired reproductive function and the causes are often multifactorial related to particularities of each disease. This review highlights how rheumatic diseases and their management affect testicular function and male fertility. A systematic review of literature of all published data after 1970 was conducted. Data was collected about fertility abnormalities in male patients with systemic lupus erythematosus, rheumatoid arthritis, dermatomyositis, ankylosing spondylitis, Behçet disease and gout. Two independent researchers carried out the search in online databases. A total of 19 articles were included addressing the following diseases: 7 systemic lupus erythematosus, 6 Behçet disease, 4 ankylosing spondylitis, 2 rheumatoid arthritis, 2 dermatomyositis and one gout. Systemic lupus erythematosus clearly affects gonadal function impairing spermatogenesis mainly due to antisperm antibodies and cyclophosphamide therapy. Behçet disease, gout and ankylosing spondylitis patients, including those under anti-TNF therapy in the latter disease, do not seem to have reduced fertility whereas in dermatomyositis, the fertility potential is hampered by disease activity and by alkylating agents. Data regarding rheumatoid arthritis is scarce, gonadal dysfunction observed as consequence of disease activity and antisperm antibodies. Reduced fertility potential is not uncommon. Its frequency and severity vary among the different rheumatic diseases. Permanent infertility is rare and often associated with alkylating agent therapy.

Evidence suggests that physicians are less likely to identify alcohol problems in females than in males. To compare the performance of family medicine residents with male and female simulated patients (SPs) posing as problem drinkers. Fifty-six family medicine residents completed a baseline survey on knowledge and attitudes towards problem drinkers. Each resident was then visited by one male and female unannounced SP. The male and female roles were similar with respect to presenting complaint (in somnia or hypertension), age, social class, and drinking history. Residents expressed slightly more positive attitudes towards female than male patients (3.32 vs. 3.09, p < .001). Residents scored higher with undetected male than with undetected female SPs on the assessment checklist (5.1 vs. 3.2, p < .045), the management checklist (4.4 vs. 3.2, p = .032), and an interpersonal rating scale (the Alcohol Skills Rating Form; 5.5 vs. 4.7, p = .023). Educational programs should focus on improving physicians' clinical skills in the identification and treatment of alcohol problems in women.

In the current cross-sectional study, we aimed to investigate the presence and severity of "male" depressive symptoms and suicidal behaviors in psychiatric patients with and without a history of child abuse and neglect, as measured by the Childhood Trauma Questionnaire (CTQ), as well as to explore the associations among childhood maltreatment, "male depression" and suicide risk. The sample consisted of 163 consecutively admitted adult inpatients (80 men; 83 women). The patients were administered the CTQ, Gotland Male Depression Scale (GMDS), and Suicidal History Self-Rating Screening Scale (SHSS). Those with a moderate-severe childhood maltreatment history were more likely to be female (p<0.05) and reported more "male depression" (p<0.001) and suicidal behaviors (p<0.01) as compared to those not having or having a minimal history of child abuse and neglect. In the multivariate analysis, only the minimization/denial scale of the CTQ (odds ratio=0.31; p<0.001) and "male depression" (odds ratio=1.83; p<0.05) were independently associated with moderate/severe history of child maltreatment. The findings suggest that exposure to abuse and neglect as a child may increase the risk of subsequent symptoms of "male depression", which has been associated with higher suicidal risk.

MS is one of the most common chronic diseases of the nervous system. Apart from disease progression, other complications such as unemployment, separation and divorce could potentially threat patients' dignity. Most of the previous studies have been done of maintaining patients' dignity in interaction with healthcare team, but studies on affecting factors of dignity in chronic patients in the society and in interaction with usual people are scarce. We aimed to investigate factors affecting dignity of Iranian patients with MS in daily living and in interaction of them with the society. In this qualitative study, 13 patients with multiple sclerosis were chosen by purposive sampling and semi-structured interviews were conducted until data saturation. The study was done in Tehran, the capital city of Iran. Factors affecting dignity were classified as 'personal factors' and 'social factors'. Personal factors consist of the following subcategories: patients' communication with self, patients' knowledge, patients' values and beliefs and patients' resources. Social factors include others' communication with patients, social knowledge, social values and beliefs and social resources. Multiple personal and social factors interfere in perceived patient dignity. In fact, interaction between personal and social factors can be influential in final perceived dignity. By focusing on whole aspects of the patients' lives, we can identify dignity-promoting or dignity-threatening factors and help patients maintain their dignity by taking appropriate measures for moderating threatening factors and improving dignity enhancing ones. © 2016 Nordic College of Caring Science.

Psychosocial predictors of affect in adult patients undergoing orthodontic treatment.

2014-02-01

In this paper we propose to study the role of psychosocial variables in affect in adult patients undergoing orthodontic treatment, considering that affect is a key variable in treatment adherence. Seventy-four patients (average age 33,24 ± 10,56) with metal multibracket-fixed orthodontic treatment were included. Patients were assessed twice. The first stage, at the beginning of treatment, included assessment of dental impact (Psychosocial Impact of Dental Aesthetics Questionnaire), trait anxiety (State-Trait Anxiety Inventory), self-esteem (Rosenberg's self-esteem scale), and self-efficacy (General Self-efficacy Scale). In the second stage, 6 months later, positive and negative affect towards treatment was assessed using the Positive and Negative Affect Scale. Dental social impact differentiates between patients with high and low negative affect, while self-efficacy differentiates between patients with high and low positive affect. Trait anxiety and self-esteem differentiate between both types of affect (positive and negative). Trait anxiety and self-esteem (when trait anxiety weight is controlled) are significant predictor variables of affective balance. These results have important practical implications, because it seems essential to adopt a bio-psychosocial model incorporating assessment methods focusing on day-to-day changes in mood and well-being.

To assess the efficacy of a modified approach with transanal total mesorectal excision (taTME) using simple customized instruments in male patients with low rectal cancer. A total of 115 male patients with low rectal cancer from December 2006 to August 2015 were retrospectively studied. All patients had a bulky tumor (tumor diameter ≥ 40 mm). Forty-one patients (group A) underwent a classical approach of transabdominal total mesorectal excision (TME) and transanal intersphincteric resection (ISR), and the other 74 patients (group B) underwent a modified approach with transabdominal TME, transanal ISR, and taTME. Some simple instruments including modified retractors and an anal dilator with a papilionaceous fixture were used to perform taTME. The operative time, quality of mesorectal excision, circumferential resection margin, local recurrence, and postoperative survival were evaluated. All 115 patients had successful sphincter preservation. The operative time in group B (240 min, range: 160-330 min) was significantly shorter than that in group A (280 min, range: 200-360 min; P = 0.000). Compared with group A, more complete distal mesorectum and total mesorectum were achieved in group B (100% vs 75.6%, P = 0.000; 90.5% vs 70.7%, P = 0.008, respectively). After 46.1 ± 25.6 mo follow-up, group B had a lower local recurrence rate and higher disease-free survival rate compared with group A, but these differences were not statistically significant (5.4% vs 14.6%, P = 0.093; 79.5% vs 65.1%, P = 0.130). Retrograde taTME with simple customized instruments can achieve high-quality TME, and it might be an effective and economical alternative for male patients with bulky tumors.

No surgical technique is reported to be the best option for gender-affirmation surgery (GAS) of the genitalia in transmen. Although patients' preferences are central when choosing a surgical technique, no studies have evaluated this factor. To investigate transmen's priorities and preferences regarding GAS of the genitalia. From November 2015 to March 2016, 54 transmen with the diagnosis of gender dysphoria who were referred to Sahlgrenska University Hospital for discussion of therapeutic steps (surgery and hormonal treatments) were asked to complete a questionnaire on different attributes achievable with GAS, such as sexual and urinary function and appearance. Forty-seven patients (87%) completed the questionnaire. Age ranged from 18 to 52 years (mean = 26 years, SD = 7.4 years). At the time of interview, no patient had undergone GAS of the genitalia. Answers to completed questionnaires. Seventy-six percent of patients identified themselves as male, and 24% wrote other terms such as "mostly male," "inter-gender" and "non-binary." Gender identity had a significant impact on patients' preferences for two questions: the importance of vaginal removal and the importance of having a penis that would be passable in places such as male dressing rooms. These items were more important to patients identifying themselves as male. The most important attributes requested were preserved orgasm ability and tactile sensation. The least important attribute was removal of the vagina, followed by having a penis of human material, minimal scarring, and size. The ability to urinate while standing was considered a high priority by some and a low priority by others. All answers ranged from "unimportant" to "imperative." This series of patients demonstrates a considerable heterogeneity among transmen in their gender identity and preferences regarding GAS of the genitalia, which supports the need for several techniques. Patients must be accurately informed on the different techniques and

The scent of inbreeding: a male sex pheromone betrays inbred males

2013-01-01

Inbreeding depression results from mating among genetically related individuals and impairs reproductive success. The decrease in male mating success is usually attributed to an impact on multiple fitness-related traits that reduce the general condition of inbred males. Here, we find that the production of the male sex pheromone is reduced significantly by inbreeding in the butterfly Bicyclus anynana. Other traits indicative of the general condition, including flight performance, are also negatively affected in male butterflies by inbreeding. Yet, we unambiguously show that only the production of male pheromones affects mating success. Thus, this pheromone signal informs females about the inbreeding status of their mating partners. We also identify the specific chemical component (hexadecanal) probably responsible for the decrease in male mating success. Our results advocate giving increased attention to olfactory communication as a major causal factor of mate-choice decisions and sexual selection. PMID:23466986

There is a compelling evidence in support of negative associations between essential trace and toxic elements in different types of cancer. The aim of the present study was to investigate the relationship between carcinogenic (As, Cd, Ni) and anti-carcinogenic (Se, Zn) trace elements in scalp hair samples of different male cancerous patients (esophagus, lung, mouth, and urinary bladder). For comparative purposes, the scalp hair samples of healthy males of the same age group (ranged 35-65 years) as controls were analyzed. Both controls and patients have the same socioeconomic status, localities, dietary habits, and smoking locally made cigarette. The scalp hair samples were oxidized by 65% nitric acid: 30% hydrogen peroxide (2:1) ratio in microwave oven followed by atomic absorption spectrometry. The validity and accuracy of the methodology were checked using certified reference material of human hair BCR 397. The mean concentrations of As, Cd, and Ni were found to be significantly higher in scalp hair samples of patients having different cancers as compared to the controls, while reverse results were obtained in the case of Se and Zn levels (p < 0.01). The study revealed that the carcinogenic processes are significantly affecting the trace elements burden and mutual interaction of essential trace and toxic elements in the cancerous patients.

Several cases of testicular adrenal rest tumours have been reported in men with congenital adrenal hyperplasia (CAH) due to the classical form of 21-hydroxylase deficiency but the prevalence has not been established. The aims of this report were to evaluate the frequency of testicular adrenal rest tissue in this population in a retrospective multicentre study involving eight endocrinology centres, and to determine whether treatment or genetic background had an impact on the occurrence of adrenal rest tissue. Testicular adrenal rest tissue (TART) was sought clinically and with ultrasound examination in forty-five males with CAH due to the classical form of 21-hydroxylase deficiency. When the diagnosis of testicular adrenal rest tumours was sought, good observance of treatment was judged on biological concentrations of 17-hydroxyprogesterone (17OHP), delta4-androstenedione, active renin and testosterone. The results of affected and non-affected subjects were compared. TART was detected in none of the 18 subjects aged 1 to 15years but was detected in 14 of the 27 subjects aged more than 15years. Five patients with an abnormal echography result had no clinical signs. Therapeutic control evaluated at diagnosis of TART seemed less effective when diagnosis was made in patients with adrenal rest tissue compared to TART-free subjects. Various genotypes were observed in patients with or without TART. Due to the high prevalence of TART in classical CAH and the delayed clinical diagnosis, testicular ultrasonography must be performed before puberty and thereafter regularly during adulthood even if the clinical examination is normal.

The maternal environment has been shown to influence female olfactory preferences through early chemosensory experience. However, little is known about the influence of the maternal environment on chemosignals. In this study, we used two inbred mouse strains, C57BL/6 (C57) and BALB/c (BALB), and explored whether adoption could alter male chemosignals and thus influence female olfactory preferences. In Experiment 1, C57 pups were placed with BALB dams. Adult BALB females then served as the subjects in binary choice tests between paired male urine odours (BALB vs. C57, BALB vs. adopted C57 and C57 vs. adopted C57). In Experiment 2, BALB pups were placed with C57 dams, and C57 females served as the subjects in binary choice tests between paired male urine odours (C57 vs. BALB, C57 vs. adopted BALB, and BALB vs. adopted BALB). In both experiments, we found that females preferred the urine of males from different genetic backgrounds, suggesting that female olfactory preferences may be driven by genetic compatibility. Cross-fostering had subtle effects on female olfactory preferences. Although the females showed no preference between the urine odours of adopted and non-adopted males of the other strain, the BALB females preferred the urine odour of BALB males to that of adopted C57 males, whereas the C57 females showed no preference between the urine odour of C57 and adopted BALB males. Using gas chromatography-mass spectrometry (GC-MS) and stepwise discriminant analysis, we found that the ratios of volatile chemicals from urine and preputial gland secretions were altered in the fostered male mice; these changes may have resulted in the behavioural changes observed in the females. Overall, the results suggest that female mice prefer urine odours from males with different genetic backgrounds; this preference may be driven by genetic compatibility. The early maternal environment influences the chemosignals of males and thus may influence the olfactory preferences of

Understanding male cancer patients' barriers to participating in cancer rehabilitation.

The aim was to describe male cancer survivors' barriers towards participation in cancer rehabilitation as a means to guiding future targeted men's cancer rehabilitation. Symbolic Interactionism along with the interpretive descriptive methodology guided the study of 35 male cancer survivors representing seven cancer types. Data were generated through a 5-month fieldwork study comprising participant observations, semi-structured individual interviews and informal conversations. The analyses revealed two overarching findings shedding light on male cancer survivors' barriers to rehabilitation: 'Fear of losing control' and 'Striving for normality'. While 'Fear of losing control' signified what the men believed rehabilitation would invoke: 'Reduced manliness', 'Sympathy and dependency' and 'Confrontation with death', 'Striving for normality' was based on what the men believed rehabilitation would hinder: 'Autonomy and purpose', 'Solidarity and fellowship' and 'Forget and move on'. This study of male cancer survivors' and cancer rehabilitation documents how masculine ideals may constitute barriers for participation in rehabilitation and provides insights about why men are underrepresented in rehabilitation. The findings can guide practice to develop research-based rehabilitation approaches focused on preserving control and normality. Further empirical evidence is needed to: (1) explore the conduct of health professionals' towards male cancer patients and (2) address gender inequalities in cancer rehabilitation. © 2015 John Wiley & Sons Ltd.

Background and objectives Recent studies demonstrated an association between depressive affect and higher mortality risk in incident hemodialysis patients. This study sought to determine whether an association also exists with hospitalization risk. Design, setting, participants, & measurements All 8776 adult incident hemodialysis patients with Medical Outcomes Study Short Form 36 survey results treated in Fresenius Medical Care North America facilities in 2006 were followed for 1 year from the date of survey, and all hospitalization events lasting >24 hours were tracked. A depressive affect score was derived from responses to two Medical Outcomes Study Short Form 36 questions (“down in the dumps” and “downhearted and blue”). A high depressive affect score corresponded with an average response of “some of the time” or more frequent occurrence. Cox and Poisson models were constructed to determine associations of depressive affect scores with risk for time to first hospitalization and risk for hospitalization events, as well as total days spent in the hospital, respectively. Results Incident patients with high depressive affect score made up 41% of the cohort and had a median (interquartile range) hospitalization event rate of one (0, 3) and 4 (0, 15) total hospital days; the values for patients with low depressive affect scores were one (0, 2) event and 2 (0, 11) days, respectively. For high-scoring patients, the adjusted hazard ratio for first hospitalization was 1.12 (1.04, 1.20). When multiple hospital events were considered, the adjusted risk ratio was 1.13 (1.02, 1.25) and the corresponding risk ratio for total hospital days was 1.20 (1.07, 1.35). High depressive affect score was generally associated with lower physical and mental component scores, but these covariates were adjusted for in the models. Conclusions Depressive affect in incident hemodialysis patients was associated with higher risk of hospitalization and more hospital days. Future

Mechanisms linking affective reactions to competition-related and competition-extraneous concerns in male martial artists

Cerin, E; Barnett, A

2011-01-01

The main aim of this study was to examine affective linkages between competition-related and competition-extraneous concern domains. A secondary purpose was to establish the contributions of pre-competition affects to post-competition performance appraisals, independent of pre-competition performance expectations. Thirty-nine highly skilled male martial artists were assessed at five random times a day for a week and 1 h before a major competition on affective states and sources of concern. They also reported their performance expectations and post-competition performance appraisals. Affective states triggered by competition-related and competition-extraneous concerns persisted in time. Carry-over effects were stronger after reports of competition-related concerns, emphasizing the subjective importance of the competitive event. Although positive (enjoyment and surprise) and negative (sadness and guilt) affective spill-over was observed from competition-extraneous to competition-related concerns, the reverse held true only for disgust. These findings may be due to the athletes' ability to regulate affective reactions within a sporting setting, in particular. Spill-over from competition-extraneous to competition-related concerns is indicative of a lesser degree of control over work/study and family life. Given that average weekly negative affects and anger/disgust were independent predictors of post-competition performance appraisals, the phenomenon of spill-over and other affective linkage mechanisms in sport warrant further investigation.

2016-01-01

The effect of oral administration of 50% ethanolic leaf extract of Citrus limon (500 and 1,000 mg/kg body weight/day) for 35 days on fertility and various male reproductive endpoints was evaluated in Parkes strain of mice. Testicular indices such as histology, 3β- and 17β-HSD enzymes activity, immunoblot expression of StAR and P450scc, and germ cell apoptosis by TUNEL and CASP- 3 expression were assessed. Motility, viability, and number of spermatozoa in the cauda epididymidis, level of serum testosterone, fertility indices, and toxicological parameters were also evaluated. Histologically, testes in extract-treated mice showed nonuniform degenerative changes in the seminiferous tubules. Treatment had adverse effects on steroidogenic markers in the testis and induced germ cell apoptosis. Significant reductions were noted in epididymal sperm parameters and serum level of testosterone in Citrus-treated mice compared to controls. Fertility of the extract-treated males was also suppressed, but libido remained unaffected. By 56 days of treatment withdrawal, alterations induced in the above parameters returned to control levels suggesting that Citrus treatment causes reversible suppression of spermatogenesis and fertility in Parkes mice. Suppression of spermatogenesis may result from germ cell apoptosis because of decreased production of testosterone. The present work indicated that Citrus leaves can affect male reproduction.

Male-mimicking females increase male-male interactions, and decrease male survival and condition in a female-polymorphic damselfly.

PubMed

Gering, Eben J

2017-05-01

Biologists are still discovering diverse and powerful ways sexual conflicts shape biodiversity. The present study examines how the proportion of females in a population that exhibit male mimicry, a mating resistance trait, influences conspecific males' behavior, condition, and survival. Like most female-polymorphic damselflies, Ischnura ramburii harbors both "andromorph" females, which closely resemble males, and sexually dimorphic "gynomorph" counterparts. There is evidence that male mimicry helps andromorphs evade detection and harassment, but males can also learn to target locally prevalent morph(s) via prior mate encounters. I hypothesized that the presence of male mimics could therefore predispose males to mate recognition errors, and thereby increase rates of costly male-male interactions. Consistent with this hypothesis, male-male interaction rates were highest in mesocosms containing more andromorph (vs. gynomorph) females. Males in andromorph-biased mesocosms also had lower final body mass and higher mortality than males assigned to gynomorph-majority treatments. Male survival and body mass were each negatively affected by mesocosm density, and mortality data revealed a marginally significant interaction between andromorph frequency and population density. These findings suggest that, under sufficiently crowded conditions, female mating resistance traits such as male mimicry could have pronounced indirect effects on male behavior, condition, and survival. © 2017 The Author(s).

Neuropeptides affecting the transfer of juvenile hormones from males to females during mating in Spodoptera frugiperda.

2014-07-01

In the polyandric moth, Spodopterafrugiperda, juvenile hormone (JH) is transferred from the male accessory reproductive glands (AG) to the female bursa copulatrix (BC) during copulation (see Hassanien et al., 2014). Here we used the RNA interference technique to study the role of allatoregulating neuropeptides in controlling the synthesis and transfer of JH during mating. Knockdown of S. frugiperda allatostatin C (Spofr-AS type C) in freshly emerged males leads to an accumulation of JH in the AG beyond that in the control and mating results in a higher transport of JH I and JH II into the female BC. Knockdown of S. frugiperda allatotropin 2 (Spofr-AT2) significantly reduces the amount of JH in the AG as well as its transfer into the female BC during copulation. Knockdown of S. frugiperda allatostatin A (Spofr-AS type A) and S. frugiperda allatotropin (Spofr-AT; Hassanien et al., 2014) only slightly affects the accumulation of JH in the AG and its transfer from the male to the female. We conclude that Spofr-AS type C and Spofr-AT2 act as true allatostatin and true allatotropin, respectively, on the synthesis of JH I and JH II in the male AG. Moreover, both peptides seem to control the synthesis of JH III in the corpora allata of adult males and its release into the hemolymph. Copyright © 2014 Elsevier Ltd. All rights reserved.

2016-01-01

ABSTRACT Background Improved targeted therapies for rheumatic diseases were developed recently resulting in a better prognosis for affected patients. Nowadays, patients are living longer and with improved quality of life, including fertility potential. These patients are affected by impaired reproductive function and the causes are often multifactorial related to particularities of each disease. This review highlights how rheumatic diseases and their management affect testicular function and male fertility. Materials and Methods A systematic review of literature of all published data after 1970 was conducted. Data was collected about fertility abnormalities in male patients with systemic lupus erythematosus, rheumatoid arthritis, dermatomyositis, ankylosing spondylitis, Behçet disease and gout. Two independent researchers carried out the search in online databases. Results A total of 19 articles were included addressing the following diseases: 7 systemic lupus erythematosus, 6 Behçet disease, 4 ankylosing spondylitis, 2 rheumatoid arthritis, 2 dermatomyositis and one gout. Systemic lupus erythematosus clearly affects gonadal function impairing spermatogenesis mainly due to antisperm antibodies and cyclophosphamide therapy. Behçet disease, gout and ankylosing spondylitis patients, including those under anti-TNF therapy in the latter disease, do not seem to have reduced fertility whereas in dermatomyositis, the fertility potential is hampered by disease activity and by alkylating agents. Data regarding rheumatoid arthritis is scarce, gonadal dysfunction observed as consequence of disease activity and antisperm antibodies. Conclusions Reduced fertility potential is not uncommon. Its frequency and severity vary among the different rheumatic diseases. Permanent infertility is rare and often associated with alkylating agent therapy. PMID:27120778

Male adiposity is detrimental for achieving clinical pregnancy rate (CPR) following assisted reproductive technologies (ART). The hypothesis that the association of male adiposity with decreased success following ART is mediated by worse embryo quality was tested. Retrospective study including 344 infertile couples undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycles was performed. Cycle determinants included number of oocytes retrieved, zygote PN-score, total number of embryos available on day 3, number of embryos transferred, composite day 3 grade for transferred embryos, composite day 3 grade per cycle, and CPR. Couples with male body mass index (BMI) over 25 kg m(-2) (overweight and obese) exhibited significantly lower CPR compared to their normal weight counterparts (46.7% vs. 32.0% respectively, P = 0.02). No significant difference was observed for any embryo quality metrics when analyzed by male BMI: mean zygote PN-scores, mean composite day 3 grades for transferred embryos or composite day 3 grades per cycle. In a multivariable logistic regression analysis adjusting for female age, female BMI, number of embryos transferred and sperm concentration, male BMI over 25 kg m(-2) was associated with a lower chance for CPR after IVF (OR = 0.17 [95% CI: 0.04-0.65]; P = 0.01) but not after ICSI cycles (OR = 0.88 [95% CI: 0.41-1.88]; P = 0.75). In this cohort, male adiposity was associated with decreased CPR following IVF but embryo quality was not affected. Embryo grading based on conventional morphologic criteria does not explain the poorer clinical pregnancy outcomes seen in couples with overweight or obese male partner.

During monitoring of monthly medians of results from patients undertaken to assess analytical stability in routine laboratory performance, the medians for serum sodium for male and female patients were found to be significantly related. Daily, weekly and monthly patient medians of serum sodium for both male and female patients were calculated from results obtained on samples from the population >18 years on three analysers in the hospital laboratory. The half-range of medians was applied as an estimate of the maximum bias. Further, the ratios between the two medians were calculated. The medians of both genders demonstrated dispersions over time, but they were closely connected in like patterns, which were confirmed by the half-range of the ratios of medians for males and females that varied from 0.36% for daily, 0.14% for weekly and 0.036% for monthly ratios over all instruments. The tight relationship between the gender medians for serum sodium is only possible when raw laboratory data are used for calculation. The two patient medians can be used to confirm both and are useful as independent estimates of analytical bias during constant calibration periods. In contrast to the gender combined median, the estimate of analytical bias can be confirmed further by calculation of the ratios of medians for males and females.

Sarcopenia is the progressive loss of muscle mass and strength, and has a risk of adverse outcomes such as disability, poor quality of life and death. As prognosis depends not only on disease aggressiveness, but also on a patient's physical condition, sarcopenia can predict survival in patients with various cancer types. However, its effects on postoperative prognosis in patients with localized non-small cell lung cancers (NSCLC) have never been reported. We retrospectively investigated 215 male patients with pathological Stage I NSCLC. L3 muscle index is defined as the cross-section area of muscle at the third lumbar vertebra level, normalized for height, and is a clinical measurement of sarcopenia. We then investigated the effect of preoperative sarcopenia on their postoperative prognosis. Our 215 subjects included 30 patients with sarcopenia. Sarcopenia was significantly associated with body mass index, nutritional condition, serum CYFRA 21-1 level and pathological stage, but not with preoperative respiratory function or performance status. Frequency of postoperative complications, length of postoperative hospital stay, thoracic drainage period or causes of death were not correlated with the presence of sarcopenia. The sarcopenia group had a significantly shorter median overall survival (32 months) than the no-sarcopenia group. Sarcopenia might not affect short-term outcomes in patients with early-stage lung cancer. Sarcopenia was a predictor of poor prognosis in male patients with Stage I NSCLC. As sarcopenic patients with NSCLC patients are at risk for significantly worse outcomes, their treatments require careful planning, even for those with Stage I disease. © The Author 2017.

To examine: 1) current knowledge on normal biologic variation of seminal parameters; 2) how stress and psychological factors affect sperm quality in fertile and infertile males; and 3) how mental illness and psychopharmacologic agents can affect male fertility. English-language Medline, Embase, and Psycinfo were searched for relevant publications (from 1970 to January 2011) for systematic review. None. None. None. Possible effects of stress, mood, and psychotropic medications on male factor fertility. Male-factor infertility is influenced by myriad factors (obesity, tobacco, etc.). Stress alone may reduce testosterone levels and spermatogenesis. Infertility assessment and treatment can lead to distress and negatively affect sperm samples. Available research has failed to control for potentially confounding variables. Although some trends have been identified, larger-scale studies that adequately control all confounding variables are needed before conclusions can be made about the relationship between stress, psychotropic agents, and male infertility.

AIM To assess the efficacy of a modified approach with transanal total mesorectal excision (taTME) using simple customized instruments in male patients with low rectal cancer. METHODS A total of 115 male patients with low rectal cancer from December 2006 to August 2015 were retrospectively studied. All patients had a bulky tumor (tumor diameter ≥ 40 mm). Forty-one patients (group A) underwent a classical approach of transabdominal total mesorectal excision (TME) and transanal intersphincteric resection (ISR), and the other 74 patients (group B) underwent a modified approach with transabdominal TME, transanal ISR, and taTME. Some simple instruments including modified retractors and an anal dilator with a papilionaceous fixture were used to perform taTME. The operative time, quality of mesorectal excision, circumferential resection margin, local recurrence, and postoperative survival were evaluated. RESULTS All 115 patients had successful sphincter preservation. The operative time in group B (240 min, range: 160-330 min) was significantly shorter than that in group A (280 min, range: 200-360 min; P = 0.000). Compared with group A, more complete distal mesorectum and total mesorectum were achieved in group B (100% vs 75.6%, P = 0.000; 90.5% vs 70.7%, P = 0.008, respectively). After 46.1 ± 25.6 mo follow-up, group B had a lower local recurrence rate and higher disease-free survival rate compared with group A, but these differences were not statistically significant (5.4% vs 14.6%, P = 0.093; 79.5% vs 65.1%, P = 0.130). CONCLUSION Retrograde taTME with simple customized instruments can achieve high-quality TME, and it might be an effective and economical alternative for male patients with bulky tumors.

In recent years, survival rates of cancer patients have increased, resulting in a shift of focus from quantity to quality of life. A key aspect of quality of life is fertility potential; patients suffering from iatrogenic infertility often become depressed. Since many cancer therapies—chemotherapy, radiotherapy and/or surgery—and even cancer itself have detrimental effects on the male reproductive system, it is important to preserve fertility before any treatment commences. Currently, the only reliable method of male fertility preservation is sperm banking. For patients who are unable to provide semen samples by the conventional method of masturbation, there are other techniques such as electroejaculation, microsurgical epididymal sperm aspiration and testicular sperm extraction that can be employed. Unfortunately, it is presently impossible to preserve the fertility potential of pre-pubertal patients. Due to the increasing numbers of adolescent cancer patients surviving treatment, extensive research is being conducted into several possible methods such as testicular tissue cryopreservation, xenografting, in vitro gamete maturation and even the creation of artificial gametes. However, in spite of its ease, safety, convenience and many accompanying benefits, sperm banking remains underutilized in cancer patients. There are several barriers involved such as the lack of information and the urgency to begin treatment, but various measures can be put in place to overcome these barriers so that sperm banking can be more widely utilized.

Epidemiological studies have shown a high prevalence of low serum testosterone levels in men with cardiovascular disease. Moreover, the tyrosine kinase receptor Axl, the ligand of which is growth arrest-specific protein 6 (GAS6), is expressed in the vasculature, and serum GAS6 levels are associated with endothelial dysfunction and cardiovascular events. Testosterone regulates GAS6 gene transcription directly, which inhibits calcification of vascular smooth muscle cells and provides a mechanistic insight into the cardioprotective action of androgens. This study was designed to determine the correlation between serum GAS6 and testosterone levels in male patients with coronary heart disease (CHD). We recruited 225 patients with CHD and 102 apparently healthy controls. Serum concentrations of GAS6 and soluble Axl were quantified by an enzyme-linked immunosorbent assay. Levels of high-sensitivity C-reactive protein, testosterone, estradiol, and other routine biochemical markers were also measured. Testosterone decreased from 432.69 ± 14.40 to 300.76 ± 6.23 ng dl-1 (P < 0.001) and GAS6 decreased from 16.20 ± 0.31 to 12.51 ± 0.19 ng ml-1 (P < 0.001) in patients with CHD, compared with control subjects. Multiple linear regression analysis showed that serum testosterone and GAS6 levels were positively associated in male patients with CHD. Alterations in GAS6 levels may influence the development of CHD. Downregulation of GAS6/Axl signaling in the presence of low sex hormone levels during disease progression is a potential mechanism by which GAS6 affects CHD. This study provides novel results regarding the influence of sex hormones on serum GAS6 levels in patients with CHD.

Mate choice decisions are central in sexual selection theory aimed to understand how sexual traits evolve and their role in evolutionary diversification. We test the hypothesis that brain size and cognitive ability are important for accurate assessment of partner quality and that variation in brain size and cognitive ability underlies variation in mate choice. We compared sexual preference in guppy female lines selected for divergence in relative brain size, which we have previously shown to have substantial differences in cognitive ability. In a dichotomous choice test, large-brained and wild-type females showed strong preference for males with color traits that predict attractiveness in this species. In contrast, small-brained females showed no preference for males with these traits. In-depth analysis of optomotor response to color cues and gene expression of key opsins in the eye revealed that the observed differences were not due to differences in visual perception of color, indicating that differences in the ability to process indicators of attractiveness are responsible. We thus provide the first experimental support that individual variation in brain size affects mate choice decisions and conclude that differences in cognitive ability may be an important underlying mechanism behind variation in female mate choice.

Schizophrenia is a heterogeneous disorder in which there is an interaction between genetic and environmental factors. Evidence related to vitamin D deficiency and schizophrenia is aresidence. Because influenced by geographical location this can affect sun exposure to individuals living in the area because the source of vitamin D for humans is exposure to sunlight. For determining differences in serum levels of vitamin D based on residence in the highland and lowland male schizophrenic patient. This study was an analytical study, by RS Jiwa Prof. dr. M. Ildrem Medan, approach to see the comparison 60 samples (30 patients live in the Highland and Lowland). Sample inspection for serum vitamin D using ELFA method. The results showed median levels of vitamin D subjects living in high land Tanah Karo was 22.20ng/mL with minimum-maximum levels of 19.3-34.5ng/mL and in the low land Pemko Medan vitamin D levels higher with median 27.95ng/mL with the minimum-maximum level of vitamin D 20.4-42.6ng/mL. Analysis using the Mann Whitney U test showed significant differences between the levels of vitamin D based on residence with a value of p = 0.001.

Schizophrenia is a dramatic mental illness with tragic manifestation. The consequences of the illness are for the individual, affected his or her family and society. Schizophrenia is one of the twenty illness that causes Years Lost due to Disability. Treating only the symptom is insufficient. The aim of treatment must include the quality of life of aschizophrenic person. This study aims to examine the relationship between cognitive impairment and performance of the person with schizophrenia. Cognitive test is scaled with Indonesian version of Montreal Cognitive Assessment (MoCA-Ina), while personal and social performance isscaled with Personal and Social Performance scale. There are many studies that search the relationship between cognitive impairment and social functioning of schizophrenic patients, but this is the first study that uses PSP and MoCA-Ina. Both PSP and MoCA-Ina are easy to use but still have high sensitivity and specificity, and perhaps can build people’s interest to use it in clinical practice. Twenty-five male schizophrenic patients were assessed in Prof. M. Ildrem Mental Hospital of North Sumatera Province of Indonesia. Positive correlations between MoCA-Ina and PSP score were identified. Clinicians should pay attention to cognitive and might give some early intervention to it.

2012-01-01

Background The high co-occurrence between borderline personality disorder and affective disorders has led many to believe that borderline personality disorder should be considered as part of an affective spectrum. The aim of the present study was to examine whether the prevalence of affective disorders are higher for patients with borderline personality disorder than for patients with other personality disorders. Methods In a national cross-sectional study of patients receiving mental health treatment in Norway (N = 36 773), we determined whether psychiatric outpatients with borderline personality disorder (N = 1 043) had a higher prevalence of affective disorder in general, and whether they had an increased prevalence of depression, bipolar disorder or dysthymia specifically. They were compared to patients with paranoid, schizoid, dissocial, histrionic, obsessive-compulsive, avoidant, dependent, or unspecified personality disorder, as well as an aggregated group of patients with personality disorders other than the borderline type (N = 2 636). Odds ratios were computed for the borderline personality disorder group comparing it to the mixed sample of other personality disorders. Diagnostic assessments were conducted in routine clinical practice. Results More subjects with borderline personality disorder suffered from unipolar than bipolar disorders. Nevertheless, borderline personality disorder had a lower rate of depression and dysthymia than several other personality disorder groups, whereas the rate of bipolar disorder tended to be higher. Odds ratios showed 34% lower risk for unipolar depression, 70% lower risk for dysthymia and 66% higher risk for bipolar disorder in patients with borderline personality disorder compared to the aggregated group of other personality disorders. Conclusions The results suggest that borderline personality disorder has a stronger association with affective disorders in the bipolar spectrum than disorders in the unipolar

Background: There are some auspicious records on applying aerobic exercise for asthmatic patients. Recently, it is suggested that rebound exercise might even increase the gains. This study was designed to compare the effects of rebound therapy to aerobic training in male asthmatic patients. Methods: Sample included 37 male asthmatic patients (20-40 years) from the same respiratory clinic. After signing the informed consent, subjects volunteered to take part in control, rebound, or aerobic groups. There was no change in the routine medical treatment of patients. Supervised exercise programs continued for 8 weeks, consisting of two sessions of 45 to 60 minutes per week. Criteria measures were assessed pre- and post exercise program. Peak exercise capacity (VO2peak) was estimated by modified Bruce protocol, Forced vital capacity (FVC), Forced expiratory volume in 1 second (FEV1), and FEV1% were measured by spirometer. Data were analyzed by repeated measure analysis of variance (ANOVA). Results: Significant interactions were observed for all 4 criteria measures (P < 0.01), meaning that both the exercise programs were effective in improving FVC, FEV1, FEV1%, and VO2peak. Rebound exercise produced more improvement in FEV1, FEV1%, and VO2peak. Conclusions: Regular exercise strengthens the respiratory muscles and improves the cellular respiration. At the same time, it improves the muscular, respiratory, and cardio-vascular systems. Effects of rebound exercise seem to be promising. Findings suggest that rebound exercise is a useful complementary means for asthmatic male patients. PMID:23717762

To indirectly evaluate the effect of androgens on neuromuscular system in humans we analyzed if an induced short-term hypogonadal state (serum total testosterone-TT<2.3ng/ml) may affect central drive to skeletal muscle and/or muscle neuro-mechanical performance. We compared voluntary and electrically evoked muscle sEMG signals from biceps brachii in nine hypogonadal male volunteers (Hypo) and in ten healthy controls (Cont). Serum TT and dihydrotestosterone (DHT) were assayed. With respect to Hypo, Cont exhibited significantly higher median frequency content (MDF) at any angular velocity; normalized MDF [95.9% (SD=23.3) vs 73.8% (SD=9.3)]; muscle fiber conduction velocity (CV) from lowest to highest angular velocities; initial MDF at fatigue test [91.78Hz (SD=22.03) vs 70.94Hz (SD=11.06)] as well as was the normalized slope [-0.64 (SD=0.14 vs -0.5 (SD=0.11)]. In the non-fatigued state, Hypo showed a slower single twitches time to peak (TTP). In Cont, half relaxation time (HRT) decreased after fatigue while increased in Hypo (p<0.05 between groups). A significant correlation between both TT and dihydrotestosterone with MDF and CV was found during voluntary contractions only. A brief exposure to very low serum TT concentration in males seem to determine a reduced excitability of the NM system which, in turn, would favor a predominant recruitment of slow twitch MUs.

To investigate the association between the human 8-oxoguanine DNA glycosylase 1 (hOGG1) gene Ser326Cys polymorphism and male subfertility in Taiwanese patients with varicocele, we made a prospective study. Ninety young male patients with varicocele (group 1), 50 young male patients with subclinical varicocele (group 2) and 30 normal young male patients without varicocele (group 3) were recruited in this study. The hOGG1 null homozygous genotype (Cys/Cys) and the occurrence of a 4,977-bp deletion in mitochondrial DNA and mitochondrial copy number in spermatozoa were determined by polymerase chain reaction. The 8-hydroxy-2'-deoxyguanosine (8-OHdG) content of DNA in the spermatozoa was measured using high-performance liquid chromatography, and total antioxidant capacity (TAC) of seminal plasma was detected electrochemically. The rates of male subfertility were 31.1% (28/90) in group 1 and 22% (11/50) in group 2. Of 39 subfertile men, 74.4% (29/39) had the hOGG1 Cys/Cys genotype. Patients in groups 1 and 2 with hOGG1 Cys/Cys genotype had significantly higher 8-OHdG content in sperm DNA, lower mitochondrial copy number in spermatozoa and lower TAC in seminal plasma than those with Ser/Ser or Ser/Cys genotype. Clinicians should pay more attention to patients with varicocele with the hOGG1 Cys/Cys genotype. © 2018 Blackwell Verlag GmbH.

Male rank affects reproductive success and offspring performance in bank voles.

Kruczek, Małgorzata; Zatorska, Magdalena

Laboratory studies reveal that in several rodent species the females prefer dominant males as mating partners. Here we investigate the correlation between males' social rank and their reproductive success. Similar numbers of females mating with relatively more dominant or relatively more subordinate males produced a litter, and parturition took place 19-21 days after mating. Relatively more dominant males tended to sire more pups than did relatively more subordinates, but the mean number of offspring per litter did not differ significantly between the two groups. Significantly more pups fathered by relatively more dominant males survived to weaning than those sired by relatively more subordinate fathers. Dominance had a long-term effect on the reproductive activity of the offspring: their rate of sexual maturation was increased. In pups sired by a relatively more dominant father, the uteruses of females, and the testes and accessory sex glands of males, were significantly heavier than those of offspring born to relatively more subordinate males. Our results suggest that social rank is an important determinant of the reproductive success of bank vole males.

HIV-infected individuals are at increased risk of incident fractures. Evaluation of trabecular bone micro-architecture is an important tool to assess bone strength, but its use has not yet been reported in middle-aged HIV-infected male individuals. The aim of the study was to compare bone micro-architecture between HIV-infected and HIV-uninfected men. In this cross-sectional study, 53 HIV-infected male individuals with a mean (± standard deviation) age of 49 ± 9 years who had been receiving antiretroviral therapy including tenofovir disoproxil fumarate (DF) for at least 60 months were compared with 50 HIV-uninfected male controls, matched for age and ethnic origin. We studied the volumetric bone density and micro-architecture of the radius and tibia using high-resolution peripheral quantitative computed tomography (HR-p QCT). Volumetric trabecular bone density was 17% lower in the tibia (P < 10(-4) ) and 16% lower in the radius (P < 10(-3) ) in HIV-infected patients compared with controls. By contrast, the cortical bone density was normal at both sites. The tibial trabecular micro-architecture differed markedly between patients and controls: bone volume/total volume (BV/TV) and trabecular number were each 13% lower (P < 10(-4) for both). Trabecular separation and inhomogeneity of the network were 18% and 24% higher in HIV-infected patients than in controls, respectively. The radial BV/TV and trabecular thickness were each 13% lower (P < 10(-3) and 10(-2) , respectively). Cortical thickness was not different between the two groups. The findings of lower volumetric trabecular bone density and disrupted trabecular micro-architectural parameters in middle-aged male HIV-infected treated patients help to explain bone frailty in these patients. © 2016 British HIV Association.

Predictors of pre- and post-competition affective states in male martial artists: a multilevel interactional approach

Cerin, E; Barnett, A

2011-01-01

The aims of this study were to examine (a) the effects of competition-related and competition-extraneous concerns on affective states; (b) the relationships of primary and secondary appraisal with affective states and (c) the main and moderating effects of personality traits on pre- and post-competition affects. Thirty-nine male elite martial artists were assessed on 12 affective states, concerns and dimensions of primary and secondary appraisal at five random times a day across 1 week before and 3 days after a competition. On the competition day, they were assessed 1 h before and immediately after the contest. Competitive trait anxiety, neuroticism and extraversion were measured at the start of the study. The competition was the most significant and stressful event experienced in the examined period and had a pervasive influence on athletes' affective states. All examined appraisal and personality factors were somewhat associated with pre- and post-competition affective states. Competitive trait anxiety was a key moderator of the relationship between cognitive appraisal and affective states. This study supports the idea that cognitive appraisal and situational and personality factors exert main and interactive effects on athletes' pre- and post-competition affects. These factors need to be accounted for in planning of emotion regulation interventions. PMID:19883381

Coevolution of female ovulatory signals and male-male competition in primates.

PubMed

Nakahashi, Wataru

2016-03-07

Visual signals of ovulation vary among primate species. Although slight ovulatory signals are considered primate ancestral traits of which some species still exhibit, some show prominent swelling of their perineal skin (exaggerated sexual swellings) and others do not exhibit any signals of ovulation (concealed ovulation). These signals strongly affect male mating behaviors. I develop an evolutionary model of female ovulatory signals and male-male competition. I assume that each male allocates his effort between attraction of females and male-male competition for dominance. Each female gains a benefit if she is fertile and free from the alpha male who always guards one of the most fertile females in the group, but suffers a cost if she expresses a different ovulatory signal from an ancestral trait. I show that various types of ovulatory signals may evolve and can be multistable. Male-male competition becomes intense when the signal honestly indicates ovulation. Ovulatory signals may evolve to be less exaggerated in unimale groups than in multimale groups and monogamy is more likely to evolve when ovulation is concealed. These results may partly explain why various types of primate ovulatory signals evolved and how they have affected primate societies. Copyright © 2015 Elsevier Ltd. All rights reserved.

Life history theory predicts a trade-off between male sexual trait expression and immunocompetence. Using burying beetles, Nicrophorus vespilloides, as a model, we investigated the relationship between male immune function, sex pheromone emission, and attractiveness under field conditions. In the first experiment, we tested whether there is a positive correlation between immune capacity, sex pheromone characteristics (quantity, relative composition, and time invested in pheromone emission), and male attractiveness. As a measurement of immune capacity, we used an individual's encapsulation ability against a novel antigen. In the second experiment, we specifically examined whether a trade-off between chemical trait expression and immune function existed. To this end, we challenged the immune system and measured the subsequent investment in sex pheromone emission and the attractiveness of the male under field conditions. We found that a male's immunocompetence was neither related to the emission of the male's sex pheromone nor to its attractiveness in the field. Furthermore, none of the immune-challenge treatments affected the subsequent investment in pheromone emission or number of females attracted. However, we showed that the same males that emitted a high quantity of their sex pheromone in the laboratory were able to attract more females in the field. Our data suggest that the chemical signal is not a reliable predictor of a male's immunocompetence but rather is a general important fitness-related trait, with a higher emission of the sex pheromone measured in the laboratory directly affecting the attractiveness of a male under field conditions.

2017-01-01

To assess both cognitive and affective empathy in patients with bipolar disorder (BD) during an acute manic or depressive episode. The study included 25 patients with BD (aged 35±14 years) during an acute manic episode, 25 bipolar patients (aged 41±14 years) during a depressive episode, and 25 healthy control subjects (aged 36±11 years). Cognitive and affective empathy were assessed using the Multifaceted Empathy Test. In both manic and depressive patients, a significant deficit in cognitive empathy was demonstrated. However, indices of affective empathy were significantly higher in the manic group than in depressed and control subjects. In the depressed patients, indices did not differ from those of healthy controls. For affective empathy, a significant positive correlation was found with intensity of manic symptoms and a negative correlation was found with intensity of depressive symptoms. No such correlations were observed with cognitive empathy. We found evidence of increased affective empathy (overempathizing) during a manic episode in bipolar patients. This phenomenon may be connected with disturbances in emotion inhibition related to anastrophic thinking and associated with increased activity of mirror neurons, all of which occur during a manic episode.

Two hundred and eighty-three chronic pain patients, consecutive admissions to the Comprehensive Pain Center of the University of Miami School of Medicine, received an extensive psychiatric evaluation based upon the American Psychiatric Association, Diagnostic and Statistical Manual of Mental Disorders (DSM-III) criteria and flowsheets. All patients received the following type of diagnoses: DSM-III axis I; DSM-III axis II, and personality type. The distribution of assigned diagnoses for the entire patient sample was reviewed and a statistical comparison between male and female patients was performed with regards to the prevalence of each diagnosis. Anxiety syndromes and depression of various diagnostic types were the most frequently assigned axis I diagnoses with over half the patient sample receiving each of these diagnoses. Males were significantly overrepresented in the axis I diagnoses of intermittent explosive disorders, adjustment disorders with work inhibitions, and alcohol abuse and other drug dependence, while females were significantly overrepresented in disorders of current depression of various diagnostic types and somatization disorders. 58.4% of the patients fulfilled criteria for axis II personality disorder diagnoses. The most frequently personality disorders found in the patient group were dependent (17.4%), passive aggressive (14.9%), and histrionic (11.7%). Males were significantly overrepresented in paranoid and narcissistic disorders while females were overrepresented in histrionic disorder. The most frequent personality types found in the patient group were compulsive (24.5%) and dependent (10.6%). All personality types were similarly distributed between the sexes. The results of the present study were compared to a previous study of DSM-III diagnoses in chronic pain patients and are discussed in terms of the prevalence of DSM-III diagnoses in the general population. Questions are raised as to the applicability of certain DSM-III diagnoses in

In 1765 Giovanni Morgagni described a syndrome consisting of hyperostosis frontalis interna (HFI), obesity and hirsutism. In 1928 Stewart and in 1930 Morel added neuropsychiatric symptoms, e.g. depression and dementia, which led to the definition of the Morgagni-Stewart-Morel Syndrome (MSM). Although mostly women were characterized in literature no gender specifity is demanded. This case report presents the rare case of a 66 year old male psychiatric patient with Morgagni-Stewart-Morel Syndrome. The patient complained of loss of concentration and difficulties with activities of daily living. Admission diagnosis was an opioid misuse on the basis of a chronic pain syndrome. In this case report we are describing clinical features, the patient history and technical (MRI) and neuropsychological tests. Although severe psychiatric symptoms and neuropsychological deficits are commonly seen in these patients, our patient showed only mild symptoms. This case reports shows the possibility of a male patient with MSM. If MSM is a separate entity or just an epiphenomena of hormone dysregulation should be investigated in further studies.

Affective alterations and poorer quality of life often persist in patients with Cushing's syndrome (CS) in remission. Brain-derived neurotrophic factor (BDNF) regulates the hypothalamic-pituitary-adrenal axis (HPA) and is highly expressed in brain areas controlling mood and response to stress. Our aims were to assess affective alterations after long-term remission of CS and evaluate whether they are associated with serum BDNF, salivary cortisol (SalF) and/or cortisone (SalE) concentrations. Thirty-six CS patients in remission (32 females/4 males; mean age (±s.d.), 48.8 ± 11.8 years; median duration of remission, 72 months) and 36 gender-, age- and BMI-matched controls were included. Beck Depression Inventory-II (BDI-II), Center for Epidemiological Studies Depression Scale (CES-D), Positive Affect Negative Affect Scale (PANAS), State-Trait Anxiety Inventory (STAI), Perceived Stress Scale (PSS) and EuroQoL and CushingQoL questionnaires were completed and measured to evaluate anxiety, depression, stress perception and quality of life (QoL) respectively. Salivary cortisol was measured using liquid chromatography/tandem mass spectrometry (LC/TMS). BDNF was measured in serum using an ELISA. Remitted CS patients showed worse scores in all questionnaires than controls: STAI (P < 0.001), BDI (P < 0.001), CES-D (P < 0.001), PANAS (P < 0.01), PSS (P < 0.01) and EuroQoL (P < 0.01). A decrease in BDNF was observed in CS vs controls (P = 0.038), and low BDNF was associated with more anxiety (r = -0.247, P = 0.037), depression (r = -0.249, P = 0.035), stress (r = -0.277, P = 0.019) and affective balance (r = 0.243, P = 0.04). Morning salivary cortisone was inversely associated with trait anxiety (r = -0.377, P = 0.040) and depressed affect (r = -0.392, P = 0.032) in CS patients. Delay to diagnosis was associated with depressive symptoms (BDI-II: r = 0.398, P = 0.036 and CES-D: r = 0.449, P = 0.017) and CushingQoL scoring (r = -0.460, P < 0.01). Low BDNF levels are associated

Many studies show high prevalence of affective disorders in obese patients. Affective temperament is a subclinical manifestation of such conditions. The 5-HTT gene encoding the serotonin transporter may be involved in both mood and eating dysregulation. The aim of this study was to investigate the influence of a polymorphism in the 5-HTT gene on affective temperament types, depressive symptoms and Body Mass Index (BMI) in obese patients. This study involved 390 patients (237 females, and 153 males) with obesity. The TEMPS-A questionnaire, Beck Depression Inventory (BDI) and Hamilton Depression Rating Scale (HDRS) were used to evaluate affective temperaments and prevalence of depression. DNA was obtained for serotonin transporter gene-linked polymorphism (5-HTTLPR) genotyping. In obese patients S/S genotype was associated with depressive and L/L with cyclothymic temperament. Subjects with L/L genotype presented significantly higher BMI and greater intensity of depressive symptoms in BDI and HDRS. Females scored higher in anxious and depressive, while males in hyperthymic, cyclothymic and irritable temperaments. Females scored higher in BDI (subjective depression) while males in HDRS (objective depression). TEMPS-A, BDI and HDRS are frequently used in studies on affective disorders. However, these methods do not examine all dimensions of mood and personality. In obese patients S allele of 5-HTTLPR was associated with development of depressive temperament while L allele corresponded with greater obesity and prevalence of depression. Different mechanisms may be involved in manifestation of depression in males and females with obesity. Copyright © 2015 Elsevier B.V. All rights reserved.

Nursing is predominantly a female profession and caring has been considered an attribute of female nurses, which could imply a noncaring image of male nurses. To determine patients' experiences and satisfaction from care provided by male nurses in a private hospital in Islamabad, Pakistan. This cross-sectional study included a purposive sample of 50 patients admitted to medical surgical units for at least 2 days and who had at least three professional interactions with a male nurse. The Newcastle Satisfaction with Nursing Scale was used for data collection. Descriptive statistics were used for data analysis. The total score for experience and satisfaction was 81 and 51, respectively. A statistically significant difference existed between experience and satisfaction scores of male and female participants, indicating that males were more pleased and satisfied with their experience of receiving care from male nurses compared to the female participants. The male nurses were concerned for their patients, they were knowledgeable about the patients' condition and care, and provided them with clear explanations of the medical and nursing procedures. However, they seem to lack interpersonal relationship with patients and did not take initiative in understanding their patients. © 2017 Wiley Periodicals, Inc.

Aims: The primary objective of this study was to analyze the association between alcohol consumption and short-term response to treatment (post intervention) in male patients with gambling disorder enrolled in a group cognitive behavioral therapy (CBT) program. Methods: The sample consisted of 111 male individuals with a diagnosis of Gambling Disorder, with a mean age of 45 years (SD = 12.2). All participants were evaluated by a comprehensive assessment battery and assigned to CBT groups of 10–14 patients attending 16 weekly outpatient sessions lasting 90 min each. Results: The highest mean pre- and post-therapy differences were recorded for the alcohol risk/dependence group on the obsessive/compulsive and anxiety dimensions of the SCL-90-R. As regards the presence of relapses and dropouts over the course of the CBT sessions, the results show a significant association with moderate effect size: patients with risk consumption or alcohol dependence were more likely to present poor treatment outcomes. Conclusions: Alcohol abuse was frequent in GD, especially in patients with low family income and high accumulated debts. High levels of somatization and high overall psychopathology (measured by the SCL-90-R) were associated with increased risk of alcohol abuse. Alcohol abuse was also associated with poor response to treatment. PMID:27065113

To investigate whether γH2AX levels were different in the spermatozoa of healthy men compared with infertility patients, and to assess the possible correlations between γH2AX and conventional semen parameters and double-stranded breaks (DSBs) identified with the use of comet assay. Prospective study. Clinical laboratory. Semen from 100 male infertile patients and 100 healthy sperm donors. Human sperm samples were analyzed in terms of World Health Organization parameters. The γH2AX levels were detected by means of flow cytometry. DSBs of sperm were detected by means of comet assay. Morphology slides were made and the sperm morphology assessed according to strict criteria. Conventional semen analyses, γH2AX levels in sperm, DNA DSBs in sperm, and correlations among γH2AX, conventional semen analyses, and DSBs. Concentration, viability, motility, and normal sperm morphology were significantly lower in male infertility patients compared with healthy men. Also, γH2AX levels and the number of DSBs were significantly higher in the sperm of infertile subjects compared with healthy men. γH2AX levels correlated negatively with conventional semen parameters and positively with DSBs. A threshold γH2AX level of 18.55% was identified as a cutoff value to discriminate infertile subjects from fertile control subjects with a specificity of 86.0% and a sensitivity of 83.0%. The positive and negative predictive values of the 18.55% γH2AX threshold were high: 87.7% and 85.5%, respectively. γH2AX levels were higher in the sperm of male infertility patients than in healthy men. γH2AX levels in sperm, as evaluated with the use of flow cytometry, might be a useful biomarker for evaluating DSBs in human spermatozoa.

We explored health providers' formative personal and professional experiences with race and Black men as a way to assess their potential influence on interactions with Black male patients. Utilizing convenience sampling with snowballing techniques, we identified healthcare providers in two urban university hospitals. We compared Black and White providers' experiences based on race and level of training. We used the Gardener's Tale to conceptualize how racism may lead to racial health disparities. A semi-structured interview guide was used to conduct in-person interviews (n = 16). Using the grounded theory approach, we conducted three types of coding to examine data patterns. We found two themes reflective of personally mediated racism: (1) perception of Black males accompanied by two subthemes (a) biased care and (b) fear and discomfort and (2) cognitive dissonance. While this latter theme is more reflective of Jones's internalized racism level, we present its results because its novelty is compelling. Perception of Black males and cognitive dissonance appear to influence providers' approaches with Black male patients. This study suggests the need to develop initiatives and curricula in health professional schools that address provider racial bias. Understanding the dynamics operating in the patient-provider encounter enhances the ability to address and reduce health disparities.

To evaluate the functional and cosmetic results of male-to-female gender-transforming surgery. Between May 2001 and April 2008 we performed 50 male-to-female gender-transforming surgeries. All patients had been cross-dressing, living as women, and receiving estrogen and progesterone for at least 12 months, which was sufficient for breast development and atrophy of the testes and prostate to occur. This hormonal therapy was suspended 1 month before the operation. The mean operative time was 190 min and the mean depth of the vagina was 10 cm. On follow-up, the most common complication (10%) was shrinkage of the neovagina, which could be corrected by a second surgical intervention. Of the 50 patients, 45 (90%) were satisfied with the esthetic results; 42 patients (84%) reported having regular sexual intercourse, 2 of whom had pain during intercourse. Of the 50 patients, 35 (70%) reported achieving clitoral orgasm. Male-to-female gender-transforming surgery can assure satisfactory cosmetic and functional results, with a reduced intra- and postoperative morbidity. Nevertheless the experience of the surgeon and the center remains central to obtaining optimal results. Copyright 2010 S. Karger AG, Basel.

PSEUDOBULBAR AFFECT IN MULTIPLE SCLEROSIS PATIENTS.

The aim of the study was to determine the prevalence of pseudobulbar affect (PBA) in patients with multiple sclerosis (MS) and to analyze the link between PBA and patient age, sex, clinical course of MS, disease duration and degree of disability. The study was conducted on 79 MS patients that underwent inpatient rehabilitation at the Lipik Special Hospital for Medical Rehabilitation in the period from August 15, 2014 to February 15, 2015. PBA is a term used for an emotional disinhibition syndrome characterized by sudden and involuntary episodes of crying or laughing which are not in proportion to the stimulus applied or occur without stimulus. The condition can be present in patients with various neurological disorders, such as amyotrophic lateral sclerosis, Alzheimer's disease, Parkinson's disease, patients having recovered from stroke, or following traumatic brain injury. The estimated prevalence in patients with MS ranges from 10% to 46.2%. As a measuring instrument in the study, we used the Center for Neurologic Study-Lability Scale (CNS-LS), where a sum 17 denoted positive finding. The total number of respondents was 79, of which 33 (41.8%) met the CNS-LS criteria for the diagnosis of PBA. There was no statistically significant correlation between PBA, age and degree of disability, although PBA was more common in women and in patients with a secondary progressive form of the disease. We found that 42.4% of respondents with positive CNS-LS criteria for PBA did not inform their neurologist on the presence of sudden mood changes. The high frequency of PBA and the fact that a significant proportion of patients did not inform the neurologist on their affective disturbances call for an active approach to diagnosis and treatment.

The aim of this study was to determine the experience and views of female patients when they were offered a chaperone by a male sexual health practitioner for a genital examination. Between November 2007 and January 2008, an anonymous survey was administered to female patients seen by male practitioners at Melbourne Sexual Health Centre. None of the 79 (95% CI 0-5%) patients who were offered a chaperone and declined one reported that they were uncomfortable declining the offer. The qualitative analysis showed that some participants appreciated being offered the option of a chaperone even if they did not want one and that the professional attributes of the practitioner influenced their decision not to have a chaperone. Only 8% (95%CI 4-15%) felt uncomfortable when asked if they would like a chaperone. The results reassure that when a female patient declines the offer of a chaperone within a sexual health clinic, the male practitioner can feel confident that this is the expression of the patient's wish.

Birth rates in males with ulcerative colitis and ileal pouch-anal anastomosis have not been studied. This study aimed to estimate birth rates in males and females with ulcerative colitis and study the impact of ileal pouch-anal anastomosis. This was a retrospective registry-based cohort study that was performed over a 30-year period. Records for parenting a child from the same period were cross-linked with patient records, and birth rates were calculated using 15 through 49 years as age limits. All data were prospectively registered. All patients with ulcerative colitis and ulcerative colitis with ileal pouch-anal anastomosis between 1980 and 2010 were identified in Danish national databases. The primary outcomes measured were birth rates in females and males with ulcerative colitis and ulcerative colitis with ileal pouch-anal anastomosis. We included 27,379 patients with ulcerative colitis (12,812 males and 14,567 females); 1544 had ileal pouch-anal anastomosis (792 males and 752 females). Patients with ulcerative colitis have slightly reduced birth rates (males at 40.8 children/1000 years, background population 43.2, females at 46.2 children/1000 years, background population 49.1). After ileal pouch-anal anastomosis, males had increased birth rates at 47.8 children/1000 years in comparison with males with ulcerative colitis without ileal pouch-anal anastomosis (40.5 children/1000 years), whereas females had reduced birth rates at 27.6 children/1000 years in comparison with females with ulcerative colitis without ileal pouch-anal anastomosis (46.8 children/1000 years). Only birth rates were investigated and not fecundability. Furthermore, there is a question about misattributed paternity, but this has previously been shown to be less than 5%. Ulcerative colitis per se has little impact on birth rates in both sexes, but ileal pouch-anal anastomosis surgery leads to a reduction in birth rates in females and an increase in birth rates in males. This has clinical

Postpartum depression (PPD) affects approximately 15% of mothers, disrupts maternal care, and can represent a form of early life adversity for the developing offspring. Intriguingly, male and female offspring are differentially vulnerable to the effects of PPD. Antidepressants, such as fluoxetine, are commonly prescribed for treating PPD. However, fluoxetine can reach offspring via breast milk, raising serious concerns regarding the long-term consequences of infant exposure to fluoxetine. The goal of this study was to examine the long-term effects of maternal postpartum corticosterone (CORT, a model of postpartum stress/depression) and concurrent maternal postpartum fluoxetine on behavioral, endocrine, and neural measures in adult male and female offspring. Female Sprague-Dawley dams were treated daily with either CORT or oil and fluoxetine or saline from postnatal days 2-23, and offspring were weaned and left undisturbed until adulthood. Here we show that maternal postpartum fluoxetine increased anxiety-like behavior and impaired hypothalamic-pituitary-adrenal (HPA) axis negative feedback in adult male, but not female, offspring. Furthermore, maternal postpartum fluoxetine increased the density of immature neurons (doublecortin-expressing) in the hippocampus of adult male offspring but decreased the density of immature neurons in adult female offspring. Maternal postpartum CORT blunted HPA axis negative feedback in males and tended to increase density of immature neurons in males but decreased it in females. These results indicate that maternal postpartum CORT and fluoxetine can have long-lasting effects on anxiety-like behavior, HPA axis negative feedback, and adult hippocampal neurogenesis and that adult male and female offspring are differentially affected by these maternal manipulations.

The objective of this study was to compare male-female differences with respect to baseline characteristics and short-term outcome in a contemporary nationwide cohort of patients who underwent isolated mitral valve (MV) surgery. All patients [N = 3411; 58% males (N = 1977)] who underwent isolated MV surgery (replacement: N = 1048, 31%; reconstruction: N = 2364, 69%) in the Netherlands between January 2007 and December 2011 were included in this study. Differences in patient and procedural characteristics and in-hospital outcome were compared between male and female patients. Female patients were generally older (mean age, 64 vs 61 years, P < 0.001), presented more often with pulmonary hypertension (P = 0.03) and had higher logistic European System for Cardiac Operative Risk Evaluation (EuroSCORE) I (P < 0.001). Male patients presented more often with prior coronary artery bypass graft surgery (P < 0.001) and active endocarditis (P = 0.002). Female patients underwent MV replacement more often (P < 0.001) and, in case of replacement, received stented bioprostheses more often (P < 0.001). In-hospital mortality rates after MV replacement were 7% (n = 33) and 7% (n = 40) in male and female patients, respectively (OR 1.08, 95% CI 0.67-1.75; P = 0.75). In-hospital mortality rates after MV reconstruction were 1.4% (n = 21) and 1.3% (n = 11) in male and female patients, respectively (OR 0.88, 95% CI 0.42-1.84; P = 0.74). There are substantial male-female differences in patient presentation and procedural aspects in isolated MV surgery in the Netherlands. Female patients are older, have more severe disease at the time of surgery and undergo valve repair less often. Future studies are needed to identify potentially modifiable patient factors to improve the outcome of female patients with MV disease. © The Author 2016.

Crohn disease is an inflammatory bowel disease (IBD) with a complex mode of inheritance. Although nucleotide binding and oligomerization domain containing 2 (NOD2) is the strongest risk factor, the cause of Crohn disease remains unknown in the majority of the cases. X-linked inhibitor of apoptosis (XIAP) deficiency causes X-linked lymphoproliferative syndrome type 2. IBD has been reported in some XIAP-deficient patients. We characterize the IBD affecting a large cohort of patients with mutations in XIAP and examine the possible pathophysiologic mechanisms. We performed a phenotypical and histologic analysis of the IBD affecting 17 patients with hemizygous mutations in XIAP, including 3 patients identified by screening 83 patients with pediatric-onset IBD. The X chromosome inactivation was analyzed in female carriers of heterozygous XIAP mutations, including 2 adults with IBD. The functional consequences of XIAP deficiency were analyzed. Clinical presentation and histology of IBD in patients with XIAP deficiency overlapped with those of patients with Crohn disease. The age at onset was variable (from 3 months to 41 years), and IBD was severe and difficult to treat. In 2 patients hematopoietic stem cell transplantation fully restored intestinal homeostasis. Monocytes of patients had impaired NOD2-mediated IL-8 and monocyte chemoattractant protein 1 (MCP-1) production, as well as IL-10, in response to NOD2 and Toll-like receptor 2/4 costimulation. Nucleotide binding and oligomerization domain containing 1 (NOD1)-mediated IL-6 and IL-8 production was defective in fibroblasts from XIAP-deficient patients. The 2 heterozygous female carriers of XIAP mutations with IBD displayed abnormal expression of the XIAP mutated allele, resulting in impaired activation of the NOD2 pathway. IBD in patients with XIAP deficiency is similar to Crohn disease and is associated with defective NOD2 function in monocytes. Importantly, we report that it is not restricted to male patients

Supplementary feeding affects the breeding behaviour of male European treefrogs (Hyla arborea)

Meuche, Ivonne; Grafe, T Ulmar

2009-01-01

Background We investigated the effects of energetic constraints on the breeding behaviour of male European treefrogs Hyla arborea and how calling males allocated additional energy supplied by feeding experiments. Results Presence in the chorus was energetically costly indicated by both fed and unfed males losing weight. Males that were supplied with additional energy did not show longer chorus tenure. Instead, fed males returned sooner to the chorus. Additionally, fed males called more often than control males, a novel response for anurans. A significantly higher calling rate was noted from males even 31 nights after supplementary feeding. Conclusion This strategy of allocating additional energy reserves to increasing calling rate is beneficial given the preference of female hylids for males calling at high rates and a female's ability to detect small incremental increases in calling rate.

Objective: To explore the association of smoking and smoking cessation with glycemic control in male patients with type 2 diabetes. Methods: From December 2013 to January 2014, a total of 7 763 male patients with type 2 diabetes, who received national basic public health service in Changshu county of Suzhou city, Huai'an and Qinghe districts of Huai'an city, Jiangsu province, were recruited by cluster sampling. Questionnaire survey and anthropometric measurements were conducted, and fasting plasma glucose (FPG) and hemoglobin A1c (HbA1c) levels were measured. Multiple linear regression model was used to evaluate the association of smoking and smoking cessation with glycemic control. Results: The prevalence of current smoking was 45.5% in male patients with type 2 diabetes. The levels of FPG and HbA1c increased with number of cigarettes smoked per day compared with non-smokers ( P <0.001). Among patients with drug treatment, the average increase of HbA1c level in current smokers with smoking duration ≥30 years and smoking index ≥40 pack-years were 0.27% (95 %CI : 0.05%-0.49%) and 0.38% (95 %CI : 0.23%-0.53%), respectively. FPG and HbA1c level decreased obviously with smoking cessation years among former smokers ( P <0.05). Among the patients receiving no drug treatment, no dose-response relationships were observed between smoking duration, smoking cessation years and levels of FPG and HbA1c. Conclusion: Cigarette smoking was negatively related with glycemic control in male type 2 diabetes patients, especially in patients with drug treatment. Smoking cessation may be beneficial for glycemic control. Smoking cessation should be encouraged for diabetes patients as early as possible.

Impact of educational messages on patient acceptance of male medical students in OB-GYN encounters.

PubMed

Buck, Katherine; Littleton, Heather

2016-09-01

Although training in obstetrics and gynecology is a key part of medical education, male students receive less extensive experience, due in part to patient refusals. However, there is limited work seeking to reduce patient refusal rates of male students. The current study examined the efficacy of two messages at increasing male medical student acceptance into a well-woman visit. A total of 656 college women participated in a simulation study where they viewed a video of a nurse asking for permission to have a male medical student participate in their well-woman visit. The 30.5% of women who refused student participation (n = 181) were randomly assigned to view a video of the nurse either describing students' medical knowledge and technical skills training (e.g. training in performing pelvic exams) or empathic skills training (e.g. training in communication about sensitive issues). They were again asked if they would be willing to have the student participate. Both messages similarly increased student acceptance with 44.8% of those receiving the empathic skills training message and 48.9% of those who received the medical/technical skills training message accepting student participation, χ(2) (1, N = 181) = 0.3, p = 0.58. Educational messages about medical student training delivered in an engaging fashion by a credible source are a potentially effective tool to increase male student acceptance into sensitive patient encounters. Future work should test these messages in real-world settings as part of a focus on patient education to increase comfort with student participation.

OBJECTIVE: To assess the relationship between sexual behaviour, urinary symptoms, urinalysis and bacteriuria in men attending STD clinics. DESIGN: A prospective study recording sexual behaviour, urinary symptoms and collecting mid-stream urine specimens. SETTING: Two West Midlands STD clinics, UK. SUBJECTS: 1086 new male patients. RESULTS: 704 patients had had sexual intercourse (SI) within 14 days of testing, 424 had urinary symptoms and 122 had pyuria. All 13 patients with positive culture had SI < 14 days before testing, urinary symptoms and pyuria. No association was found between sexual orientation, type of SI, number of sexual partners, condom usage and bacteriuria. CONCLUSION: Bacteriuria does not behave as an STD but SI may be a factor in acquiring bacteriuria. Dysuria with or without urethral discharge is the most predictive symptom of bacteriuria. Pyuria has a high sensitivity for predicting bacteriuria among males. PMID:8976831

The second article in this series, Standards for Clinical Trials in Male and Female Sexual Dysfunction, focuses on measurement of patient-reported outcomes (PROs). Together with the design of appropriate phase I to phase IV clinical trials, the development, validation, choice, and implementation of valid PRO measurements-the focus of the present article-form the foundation of research on treatments for male and female sexual dysfunctions. PRO measurements are assessments of any aspect of a patient's health status that come directly from the patient (ie, without the interpretation of the patient's responses by a physician or anyone else). PROs are essential for assessing male and female sexual dysfunction and treatment response, including symptom frequency and severity, personal distress, satisfaction, and other measurements of sexual and general health-related quality of life. Although there are some relatively objective measurements of sexual dysfunction (ie, intravaginal ejaculatory latency time, frequency of sexual activity, etc), these measurements do not comprehensively assess the occurrence and extent of sexual dysfunction or treatment on the patient's symptoms, functioning, and well-being. Data generated by a PRO instrument can provide evidence of a treatment benefit from the patient's perspective. Copyright © 2016 International Society for Sexual Medicine. Published by Elsevier Inc.

The relationships between five classes of Japanese people (i.e., 96 centenarians, 96 Alzheimer's disease (AD) patients, 96 Parkinson's disease (PD) patients, 96 type 2 diabetic (T2D) patients, and 96 healthy non-obese young males) and their mitochondrial single nucleotide polymorphism (mtSNP) frequencies at individual mtDNA positions of the entire mitochondrial genome were examined using the radial basis function (RBF) network and the modified method. New findings of mitochondrial haplogroups were obtained for individual classes. The five classes of people were associated with the following haplogroups: Japanese centenarians-M7b2, D4b2a, and B5b; Japanese AD patients-G2a, B4c1, and N9b1; Japanese PD patients-M7b2, B4e, and B5b; Japanese T2D patients-B5b, M8a1, G, D4, and F1; and Japanese healthy non-obese young males- D4g and D4b1b. From the points of common haplogroups among the five classes, the centenarians have the common haplogroups M7b2 and B5b with the PD patients and common haplogroup B5b with the T2D patients. In addition, the 112 Japanese semi-supercentenarians (over 105 years old) recently reported were also examined by the method proposed. The results obtained were the haplogroups D4a, B4c1a, M7b2, F1, M1, and B5b. These results are different from the previously reported haplogroup classifications. As the proposed analysis method can predict a person's mtSNP constitution and the probabilities of becoming a centenarian, AD patient, PD patient, or T2D patient, it may be useful in initial diagnosis of various diseases.

This study examined the effects of xylitol on mouse intestinal microbiota and urinary isoflavonoids. Xylitol is classified as a sugar alcohol and used as a food additive. The intestinal microbiota seems to play an important role in isoflavone metabolism. Xylitol feeding appears to affect the gut microbiota. We hypothesized that dietary xylitol changes intestinal microbiota and, therefore, the metabolism of isoflavonoids in mice. Male mice were randomly divided into two groups: those fed a 0.05% daidzein with 5% xylitol diet (XD group) and those fed a 0.05% daidzein-containing control diet (CD group) for 28 days. Plasma total cholesterol concentrations were significantly lower in the XD group than in the CD group (p < 0.05). Urinary amounts of equol were significantly higher in the XD group than in the CD group (p < 0.05). The fecal lipid contents (% dry weight) were significantly greater in the XD group than in the CD group (p < 0.01). The cecal microbiota differed between the two dietary groups. The occupation ratios of Bacteroides were significantly greater in the CD than in the XD group (p < 0.05). This study suggests that xylitol has the potential to affect the metabolism of daidzein by altering the metabolic activity of the intestinal microbiota and/or gut environment. Given that equol affects bone health, dietary xylitol plus isoflavonoids may exert a favorable effect on bone health.

In this cross-sectional study, we investigated volumetric bone mineral density (vBMD), bone microstructure, and biomechanical competence of the distal radius in male patients with rheumatoid arthritis (RA). The study cohort comprised 50 male RA patients of average age of 61.1 years and 50 age-matched healthy males. Areal BMD (aBMD) of the hip, lumbar spine, and distal radius was measured by dual-energy X-ray absorptiometry. High-resolution peripheral quantitative computed tomography (HR-pQCT) of the distal radius provided measures of cortical and trabecular vBMD, microstructure, and biomechanical indices. aBMD of the hip but not the lumbar spine or ultradistal radius was significantly lower in RA patients than controls after adjustment for body weight. Total, cortical, and trabecular vBMD at the distal radius were, on average, -3.9% to -23.2% significantly lower in RA patients, and these differences were not affected by adjustment for body weight, testosterone level, or aBMD at the ultradistal radius. Trabecular microstructure indices were, on average, -8.1% (trabecular number) to 28.7% (trabecular network inhomogeneity) significantly inferior, whereas cortical pore volume and cortical porosity index were, on average, 80.3% and 63.9%, respectively, significantly higher in RA patients. RA patients also had significantly lower whole-bone stiffness, modulus, and failure load, with lower and more unevenly distributed cortical and trabecular stress. Density and microstructure indices significantly correlated with disease activity, severity, and levels of pro-inflammatory cytokines (interleukin [IL] 12p70, tumor necrosis factor, IL-6 and IL-1β). Ten RA patients had focal periosteal bone apposition most prominent at the ulnovolar aspect of the distal radius. These patients had shorter disease duration and significantly higher cortical porosity. In conclusion, HR-pQCT reveals significant alterations of bone density, microstructure, and strength of the distal radius in

Microdeletions at DYS448 and DYS387S1 associate with increased risk of male infertility.

Male infertility affects many people of reproductive age. Diagnosis and therapies based on descriptive semen parameters have helped some of the infertility patients; however, further progress in reproductive therapy demands a better understanding of the molecular and genetic causes for male infertility. Although Y chromosome microdeletions have been a hot subject of genetic studies on male infertility, the relationship between male infertility and microdeletions at Y chromosome loci DYS448, DYS387, and DYS627 remains unclear. Here we analyzed the microdeletions at these three loci in 200 infertility male patients and 200 healthy subjects and showed that microdeletions at DYS448 and DYS387 correlate with male infertility. Our results suggest that genetic analyses of Y chromosome loci DYS448 and DYS387 can be genetic markers for reproductive diagnosis and therapy.

Responses of female rock lizards to multiple scent marks of males: effects of male age, male density and scent over-marking.

PubMed

Martín, José; López, Pilar

2013-03-01

Scent-marked substrates may inform conspecifics on the characteristics of territorial males. Scent-marks of male Carpetan rock lizards (Iberolacerta cyreni) affect space use of females, which by selecting an area may increase the probability of mating with the male that has scent-marked that area. However, males do not hold exclusive territories, and scent-marks of different individual males are often together. This may provide complex information from multiple sources on the social structure. Here, we examined female preference in response to scent marks of various males and combinations in a laboratory experiment. Females preferred areas scent-marked by territorial old males against those scent-marked by young satellite-sneaker males. This reflected the known preference of females for mating with old males. In a second experiment, females preferred areas scent-marked by two males to areas of similar size marked by a single male. This may increase the probability of obtaining multiple copulations with different males, which may favour sperm competition and cryptic female choice, or may be a way to avoid infertile males. Finally, when we experimentally over-marked the scent-marks of an old male with scent-marks of a young male, females did not avoid, nor prefer, the over-marked area, suggesting that the quality of the old male may override the presence of a satellite male. We suggest that, irrespective of the causes underlying why a female selects a scent-marked area, this strategy may affect her reproductive success, which may have the same evolutionary consequences that "direct" mate choice decisions of other animals.

Reduced rDNA Copy Number Does Not Affect “Competitive” Chromosome Pairing in XYY Males of Drosophila melanogaster

PubMed Central

Maggert, Keith A.

2014-01-01

The ribosomal DNA (rDNA) arrays are causal agents in X-Y chromosome pairing in meiosis I of Drosophila males. Despite broad variation in X-linked and Y-linked rDNA copy number, polymorphisms in regulatory/spacer sequences between rRNA genes, and variance in copy number of interrupting R1 and R2 retrotransposable elements, there is little evidence that different rDNA arrays affect pairing efficacy. I investigated whether induced rDNA copy number polymorphisms affect chromosome pairing in a “competitive” situation in which complex pairing configurations were possible using males with XYY constitution. Using a common normal X chromosome, one of two different full-length Y chromosomes, and a third chromosome from a series of otherwise-isogenic rDNA deletions, I detected no differences in X-Y or Y-Y pairing or chromosome segregation frequencies that could not be attributed to random variation alone. This work was performed in the context of an undergraduate teaching program at Texas A&M University, and I discuss the pedagogical utility of this and other such experiments. PMID:24449686

To identify metabolites that are associated with an overactive bladder (OAB) using metabolomics. A total of 58 male patients without apparent neurologic disease completed 24-hour bladder diaries of their micturition behavior and International Prostate Symptom Score (IPSS) for the assessment of micturition behavior and lower urinary tract symptoms. Urgency was defined as an IPSS urgency score of ≥2 (OAB group), and patients with IPSS urgency scores of ≤1 belonged to the control group. A comprehensive study of plasma metabolites was also conducted using capillary electrophoresis time-of-flight mass spectrometry. Metabolite levels were compared between the control and OAB groups using the Mann-Whitney U test. Potential metabolite biomarkers were selected using multivariate logistic regression analysis. Of the 58 subjects, the control and OAB groups consisted of 32 and 26 male patients, respectively. Nocturnal urinary volume, 24-hour micturition frequency, nocturnal micturition frequency, and the nocturia index were significantly higher in the OAB group. Metabolomic analysis revealed 60 metabolites in the subjects' plasma. The levels of 11 metabolites differed between the control and OAB groups. Multivariate analysis showed that an increased glutamate level and reduced arginine, glutamine, and inosine monophosphate levels are significantly associated with OAB in male patients. Reduced levels of asparagine and hydroxyproline could also be associated with OAB. Urgency is associated with abnormal metabolism. Analyses of amino acid profiles might aid the search for new treatment targets for OAB. Copyright © 2018 Elsevier Inc. All rights reserved.

It should be recognized that sexuality in the aging male is of such import that a complete sexual history must be performed. By taking a complete sexual history, facts can be obtained that will allow for appropriate focus relating to a holistic evaluation and will enable us to dispel antiquated sexual myths pertaining to the aging male. If initiated by the history taker, questions concerning sexuality may be discussed more comfortably by the patient. Erectile dysfunction, male sexual response cycle, testosterone, sexually transmitted diseases, human immunodeficiency virus, long-term illness, along with religion and culture are explored in this article with the aim of improving one's knowledge base, self reflection, and awareness of the importance of male sexuality. A complete understanding and appreciation of the aging male's medical history, surgical history, social history, and emotional history as well as his sexual, cultural, and religious concepts will allow the health care provider to better analyze information, and to recommend and provide appropriate advice and treatment to the aging male patient.

Ureaplasma spp. have gained increasing recognition as pathogens in both adult and neonatal patients with multiple clinical presentations. However, the clonality of this organism in the male population and infertile couples in China is largely unknown. In this study, 96 (53 U. parvum and 43 U. urealyticum) of 103 Ureaplasma spp. strains recovered from genital specimens from male patients and 15 pairs of infertile couples were analyzed using multilocus sequence typing (MLST)/expanded multilocus sequence typing (eMLST) schemes. A total of 39 sequence types (STs) and 53 expanded sequence types (eSTs) were identified, with three predominant STs (ST1, ST9 and ST22) and eSTs (eST16, eST41 and eST82). Moreover, phylogenetic analysis revealed two distinct clusters that were highly congruent with the taxonomic differences between the two Ureaplasma species. We found significant differences in the distributions of both clusters and sub-groups between the male and female patients (P < 0.001). Moreover, 66.7% and 40.0% of the male and female partners of the infertile couples tested positive for Ureaplasma spp. The present study also attained excellent agreement of the identification of both Ureaplasma species between paired urine and semen specimens from the male partners (k > 0.80). However, this concordance was observed only for the detection of U. urealyticum within the infertile couples. In conclusion, the distributions of the clusters and sub-groups significantly differed between the male and female patients. U. urealyticum is more likely to transmit between infertile couples and be associated with clinical manifestations by the specific epidemic clonal lineages. PMID:28859153

Data on pituitary imaging in adult male patients presenting with hypogonadotrophic hypogonadism (HH) and no known pituitary disease are scarce. To assess the usefulness of pituitary imaging in the evaluation of men presenting with HH after excluding known pituitary disorders and hyperprolactinemia. A historical prospective cohort of males with HH. Men who presented for endocrine evaluation from 2011 to 2014 with testosterone levels <10.4 nmol/L (300 ng/mL), normal LH and FSH levels and no known pituitary disease. Seventy-five men were included in the analysis. Their mean age and BMI were 53.4 ± 14.8 years and 30.7 ± 5.2 kg/m2, respectively. Mean total testosterone, LH, and FSH were 6.2 ± 1.7 nmol/L, 3.4 ± 2 and 4.7 ± 3.1 mIU/L, respectively. Prolactin level within the normal range was obtained in all men (mean 161 ± 61, range 41-347 mIU/L). Sixty-two men had pituitary MRI and 13 performed CT. In 61 (81.3%) men pituitary imaging was normal. Microadenoma was found in 8 (10.7%), empty sella and thickened pituitary stalk in one patient (1.3%) each. In other four patients (5.3%) a small or mildly asymmetric pituitary gland was noted. No correlation was found between testosterone level and the presence of pituitary anomalies. This study suggests that the use of routine hypothalamic-pituitary imaging in the evaluation of IHH, in the absence of clinical characteristics of other hormonal loss or sellar compression symptoms, will not increase the diagnostic yield of sellar structural abnormalities over that reported in the general population.

Our aim was to assess short-term natural course of hypogonadism diagnosed during hospitalization for acute disease in aged male patients after discharge. A group of 43 hypogonadal males, aged 86.7±5.7 year, was studied. Serum concentrations of testosterone (T) and gonadotropins (follicle-stimulating hormone, FSH, and luteinizing hormone, LH) were measured in every patient both at admission and one month after discharge. Mean serum T at entry was 115.4±48.0 ng/dl. Hypogonadism was hyper-, hypo-, and normogonadotropic in 20 (46.5%), 20 (46.5%), and 3 (7.0%) patients, respectively. One month after discharge serum T concentrations increased significantly (230.9±135.6 ng/dl, p<0.001). At this point, more than half of the patients (n=27, 62.8%) showed normal serum T concentrations. Both gonadotropins, FSH (p<0.001), and LH (p=0.04) also increased one month after discharge. Approximately, half of the patients (13, 48.1%) who normalized serum T concentrations also showed normal serum gonadotropin concentrations. Patients who normalized their serum T concentrations one month after discharge showed significantly higher baseline values of T (134.7±33.9 ng/dl) than those who persisted with hypogonadism (n=16, 32.7%; 82.8±51.6 ng/dl, p<0.001). Lastly, serum T was the only independent predictor for achieving eugonadal status (OR 1.030; CI 95%, 1.010-1.050; p<0.001). In conclusion, about 63% of aged patients hospitalized for acute illness with hypogonadism discovered during hospitalization spontaneously normalize their serum T concentrations one month after discharge. Serum gonadotropin concentrations also increased after discharge. Serum T levels at admission was an independent predictor for the normalization of serum T concentrations.

Circumcision has been found to be an effective strategy for lowering the transmission of HIV in Africa. The Luke Commission, a mobile hospital outreach program, has used this information to decrease the rate of HIV in Swaziland by performing voluntary male medical circumcisions throughout the country. During many of these circumcisions, genital medical conditions and penile abnormalities are simultaneously discovered and corrected. The goal of our study was to evaluate the prevalence of penile abnormalities discovered and treated during voluntary male medical circumcisions performed by The Luke Commission (TLC) throughout rural Swaziland. We completed a retrospective analysis of all male patients who underwent voluntary male medical circumcision performed by TLC during a period from June-August, 2014. The penile abnormalities included: phimosis, paraphimosis, epispadias, hypospadias, ulcers, balanitis, torsion, and foreskin adherent to the glans. Of 929 total circumcisions, 771 (83%) patients had at least one pre-existing penile abnormality identified during their examinations and procedures, totaling 1110 abnormalities. Three specific abnormalities were detected - phimosis, adherent foreskin, and hypospadias. The 6-12 and 13-19 age groups had adequate sample sizes to yield precise estimates of prevalence (age group 6-12: 87% (95% confidence interval [CI]=84-90%; age group 13-19: 79% (95% CI=74-84%). The Luke Commission is improving the lives of children and adults with limited access to healthcare through regular preoperative evaluations during male circumcision, and the organization is setting an example for other international healthcare groups.

Obesity is a pandemic and is associated with multiple medical problems including subfertility. Male obesity has been associated with altered semen parameters and reproductive hormonal levels, including a reduced testosterone:estradiol (T:E₂) ratio. Treatment methods employed for obesity-related male subfertility include gonadotropin administration, weight loss, and aromatase inhibitors. Letrozole is a highly effective nonsteroidal aromatase inhibitor that has been used to treat male subfertility in several case series with promising results. Adequately designed randomized controlled studies are needed to produce evidence-based data on the role of aromatase inhibitors in male subfertility management and evaluate the side-effect profile.

This study assessed characteristics of psychiatric patients for whom financial considerations affected the provision of "optimal" treatment. Psychiatrists reported that for 33.8 percent of 1,228 patients from a national sample, financial considerations such as managed care limitations, the patient's personal finances, and limitations inherent in the public care system adversely affected the provision of optimal treatment. Patients were more likely to have their treatment adversely affected by financial considerations if they were more severely ill, had more than one behavioral health disorder or a psychosocial problem, or were receiving treatment under managed care arrangements. Patients for whom financial considerations affect the provision of optimal treatment represent a population for whom access to treatment may be particularly important.

Background Patient gender plays a significant role in patient-physician communication, patient illness understanding and aggressiveness of end of life (EoL) care. However, little is known about the extent to which gender differences in the effects of EoL discussions on EoL care contribute to gender differences in EoL care. The present study aims to determine if gender differences exist in receipt of intensive care unit (ICU) care near death and in the association between EoL discussions and receipt of ICU EoL care. Methods Multi-site, prospective, cohort study of patients (N=353) with metastatic cancers, identified as terminally ill at study enrollment and interviewed a median of 4.1 months before their deaths. Postmortem chart reviews and caregiver interviews documented ICU stays in the last week of life. Results Patients who received ICU care at the EoL were more likely to be male than those who did not (73% male vs. 52% male, p=0.02). Adjusting for potential confounds, male patients reporting an EoL discussion were less likely to have an ICU stay in the last week of life than male patients with no EoL discussion (AOR=0.26, 95% CI 0.07–0.91; p=0.04). There was no association between EoL discussions and ICU stays near death among female patients. Conclusions Men with advanced cancers are more likely than women to receive aggressive, non-beneficial, ICU care near death. Gender differences in effects of EoL discussions on EoL care likely contribute to, and may even explain, gender differences in receipt of ICU care in the last week of life. PMID:25975179

Inhibition of cholesterol biosynthesis by hydroxymethyl glutaryl coenzyme A (HMG-CoA) reductase inhibitors could, in theory, adversely affect male gonadal function because cholesterol is a precursor of steroid hormones. The objective of this randomized double-blind trial was to compare the effects of simvastatin, pravastatin, and placebo on gonadal testosterone production and spermatogenesis. After a 6-week placebo and lipid-lowering diet run-in period, 159 male patients aged 21 to 55 years with type IIa or IIb hypercholesterolemia, low-density lipoprotein (LDL) cholesterol between 145 and 240 mg/dL, and normal basal levels of testosterone were randomly assigned to treatment with simvastatin 20 mg (n = 40), simvastatin 40 mg (n = 41), pravastatin 40 mg (n = 39), or placebo (n = 39) once daily. After 24 weeks of treatment, mean total cholesterol levels were decreased 24% to 27% and mean LDL cholesterol was decreased 30% to 34% in the 3 active-treatment groups (P < .001 for all comparisons to placebo). At 24 weeks, there were no statistically significant differences between the placebo group and any of the active-treatment groups for the change from baseline in testosterone, human chorionic gonadotropin (hCG)stimulated testosterone, free testosterone index, follicle-stimulating hormone (FSH), luteinizing hormone (LH), or sex hormone-binding globulin (SHBG). Moreover, there were no statistically significant differences at week 12 or week 24 for the change from baseline in sperm concentration, ejaculate volume, or sperm motility for any active treatment relative to placebo. Both simvastatin and pravastatin were well tolerated. In summary, we found no evidence for clinically meaningful effects of simvastatin or pravastatin on gonadal testosterone production, testosterone reserve, or multiple parameters of semen quality.

Cardiovascular fitness in late adolescence is associated with future risk of depression. Relationships with other mental disorders need elucidation. This study investigated whether fitness in late adolescence is associated with future risk of serious non-affective mental disorders. Further, we examined how having an affected brother might impact the relationship. Prospective, population-based cohort study of 1 109 786 Swedish male conscripts with no history of mental illness, who underwent conscription examinations at age 18 between 1968 and 2005. Cardiovascular fitness was objectively measured at conscription using a bicycle ergometer test. During the follow-up (3-42 years), incident cases of serious non-affective mental disorders (schizophrenia and schizophrenia-like disorders, other psychotic disorders and neurotic, stress-related and somatoform disorders) were identified through the Swedish National Hospital Discharge Register. Cox proportional hazards models were used to assess the influence of cardiovascular fitness at conscription and risk of serious non-affective mental disorders later in life. Low fitness was associated with increased risk for schizophrenia and schizophrenia-like disorders [hazard ratio (HR) 1.44, 95% confidence interval (CI) 1.29-1.61], other psychotic disorders (HR 1.41, 95% CI 1.27-1.56), and neurotic or stress-related and somatoform disorders (HR 1.45, 95% CI 1.37-1.54). Relationships persisted in models that included illness in brothers. Lower fitness in late adolescent males is associated with increased risk of serious non-affective mental disorders in adulthood.

In Crohn disease, bowel-preserving surgery is necessary to prevent short bowel syndrome due to repeated operations. This study aimed to determine the remnant small bowel length cut-off and to evaluate the clinical factors related to nutritional status after small bowel resection in Crohn disease.We included 394 patients (69.3% male) who underwent small bowel resection for Crohn disease between 1991 and 2012. Patients who were classified as underweight (body mass index < 17.5) or at high risk of nutrition-related problems (modified nutritional risk index < 83.5) were regarded as having a poor nutritional status. Preliminary remnant small bowel length cut-offs were determined using receiver operating characteristic curves. Variables associated with poor nutritional status were assessed retrospectively using Student t tests, chi-squared tests, Fisher exact tests, and logistic regression analyses.The mean follow-up period was 52.9 months and the mean patient ages at the time of the last bowel surgery and last follow-up were 31.2 and 35.7 years, respectively. The mean remnant small bowel length was 331.8 cm. Forty-three patients (10.9%) underwent ileostomy, 309 (78.4%) underwent combined small bowel and colon resection, 111 (28.2%) had currently active disease, and 105 (26.6%) underwent at least 2 operations for recurrent disease. The mean body mass index and modified nutritional risk index were 20.6 and 100.8, respectively. The independent factors affecting underweight status were remnant small bowel length ≤240 cm (odds ratio: 4.84, P < 0.001), ileostomy (odds ratio: 4.70, P < 0.001), and currently active disease (odds ratio: 4.16, P < 0.001).

Reproductive behavior in male rodents is made up of anticipatory and consummatory elements which are regulated in the brain by sensory systems, reward circuits and hormone signaling. Gonadal steroids play a key role in the regulation of male sexual behavior via steroid receptors in the hypothalamus and preoptic area. Typical patterns of male reproductive behavior have been characterized, however these are not fixed but are modulated by adult experience. We assessed the effects of repeated sexual experience on male reproductive behavior of C57BL/6 mice; including measures of olfactory investigation of females, mounting, intromission and ejaculation. The effects of sexual experience on the number of cells expressing either androgen receptor (AR) or estrogen receptor alpha (ERα) in the primary brain nuclei regulating male sexual behavior was also measured. Sexually experienced male mice engaged in less sniffing of females before initiating sexual behavior and exhibited shorter latencies to mount and intromit, increased frequency of intromission, and increased duration of intromission relative to mounting. No changes in numbers of ERα-positive cells were observed, however sexually experienced males had increased numbers of AR-positive cells in the medial preoptic area (MPOA); the primary regulatory nucleus for male sexual behavior. These results indicate that sexual experience results in a qualitative change in male reproductive behavior in mice that is associated with increased testosterone sensitivity in the MPOA and that this nucleus may play a key integrative role in mediating the effects of sexual experience on male behavior.

Flowering plant genomes encode multiple cation/H + exchangers (CHXs) whose functions are largely unknown. AtCHX17, AtCHX18, and AtCHX19 are membrane transporters that modulate K+ and pH homeostasis and are localized in the dynamic endomembrane system. Loss of function reduced seed set, but the particular phase(s) of reproduction affected was not determined. Pollen tube growth and ovule targeting of chx17chx18chx19 mutant pollen appeared normal, but reciprocal cross experiments indicate a largely male defect. Although triple mutant pollen tubes reach ovules of a wild-type pistil and a synergid cell degenerated, half of those ovules were unfertilized or showed fertilization of the eggmore » or central cell, but not both female gametes. Fertility could be partially compromised by impaired pollen tube and/or sperm function as CHX19 and CHX18 are expressed in the pollen tube and sperm cell, respectively. When fertilization was successful in self-pollinated mutants, early embryo formation was retarded compared with embryos from wild-type ovules receiving mutant pollen. Thus CHX17 and CHX18 proteins may promote embryo development possibly through the endosperm where these genes are expressed. The reticulate pattern of the pollen wall was disorganized in triple mutants, indicating perturbation of wall formation during male gametophyte development. Lastly, as pH and cation homeostasis mediated by AtCHX17 affect membrane trafficking and cargo delivery, these results suggest that male fertility, sperm function, and embryo development are dependent on proper cargo sorting and secretion that remodel cell walls, plasma membranes, and extracellular factors.« less

The genetic causes of male factor infertility: a review.

2010-01-01

To illustrate the necessity for an enhanced understanding of the genetic basis of male factor infertility, to present a comprehensive synopsis of these genetic elements, and to review techniques being utilized to produce new insights in fertility research. Male factor infertility is a complex disorder that affects a large sector of the population; however, many of its etiologies are unknown. By elucidating the underlying genetic basis of infertile phenotypes, it may be possible to discover the causes of infertility and determine effective treatments for patients. The PubMed database was consulted for the most relevant papers published in the last 3 years pertaining to male factor infertility using the keywords "genetics" and "male infertility." Advances have been made in the characterization of the roles of specific genes, but further research is necessary before these results can be used as guidelines for diagnosing and treating male factor infertility. The accurate transmission of epigenetic information also has considerable influence on fertility in males and on the fertility of their offspring. Analysis of the genetic factors that impact male factor infertility will provide valuable insights into the creation of targeted treatments for patients and the determination of the causes of idiopathic infertility. Novel technologies that analyze the influence of genetics from a global perspective may lead to further developments in the understanding of the etiology of male factor infertility through the identification of specific infertile phenotype signatures.

Female major histocompatibility complex type affects male testosterone levels and sperm number in the horse (Equus caballus)

Odours of vertebrates often contain information about the major histocompatibility complex (MHC), and are used in kin recognition, mate choice or female investment in pregnancy. It is, however, still unclear whether MHC-linked signals can also affect male reproductive strategies. We used horses (Equus caballus) to study this question under experimental conditions. Twelve stallions were individually exposed either to an unfamiliar MHC-similar mare and then to an unfamiliar MHC-dissimilar mare, or vice versa. Each exposure lasted over a period of four weeks. Peripheral blood testosterone levels were determined weekly. Three ejaculates each were collected in the week after exposure to both mares (i.e. in the ninth week) to determine mean sperm number and sperm velocity. We found high testosterone levels when stallions were kept close to MHC-dissimilar mares and significantly lower ones when kept close to MHC-similar mares. Mean sperm number per ejaculate (but not sperm velocity) was positively correlated to mean testosterone levels and also affected by the order of presentation of mares: sperm numbers were higher if MHC-dissimilar mares were presented last than if MHC-similar mares were presented last. We conclude that MHC-linked signals influence testosterone secretion and semen characteristics, two indicators of male reproductive strategies. PMID:25904670

We previously reported that perinatal exposure to hypergravity affects cerebellar structure and motor coordination in rat neonates. In the present study, we explored the hypothesis that neonatal cerebellar structure and motor coordination may be particularly vulnerable to the effects of hypergravity during specific developmental stages. To test this hypothesis, we compared neurodevelopment, motor behavior and cerebellar structure in rat neonates exposed to 1.65 G on a 24-ft centrifuge during discrete periods of time: the 2nd week of pregnancy [gestational day (G) 8 through G15; group A], the 3rd week of pregnancy (G15 through birth on G22/G23; group B), the 1st week of nursing [birth through postnatal day (P) 6; group C], the 2nd and 3rd weeks of nursing (P6 through P21; group D), the combined 2nd and 3rd weeks of pregnancy and nursing (G8 through P21; group E) and stationary control (SC) neonates (group F). Prenatal exposure to hypergravity resulted in intrauterine growth retardation as reflected by a decrease in the number of pups in a litter and lower average mass at birth. Exposure to hypergravity immediately after birth impaired the righting response on P3, while the startle response in both males and females was most affected by exposure during the 2nd and 3rd weeks after birth. Hypergravity exposure also impaired motor functions, as evidenced by poorer performance on a rotarod; while both males and females exposed to hypergravity during the 2nd and 3rd weeks after birth performed poorly on P21, male neonates were most dramatically affected by exposure to hypergravity during the second week of gestation, when the duration of their recorded stay on the rotarod was one half that of SC males. Cerebellar mass was most reduced by later postnatal exposure. Thus, for the developing rat cerebellum, the postnatal period that overlaps the brain growth spurt is the most vulnerable to hypergravity. However, male motor behavior is also affected by midpregnancy exposure to

It is important to assess outcomes for medical interventions in order to focus scarce resources on outcomes with a known positive benefit. An open, observational study was performed to assess the clinical outcomes of 600 male patients with a genital skin problem attending a specialist secondary care dermatology facility. Patients were mainly referred by general practitioners and genitourinary medicine physicians. Outcome was measured at 3 and 6 months, and was determined by clinical examination and assessment of patient symptoms. The mean age of the group was 45.3 years. The commonest diagnoses were lichen sclerosus (30.5%), balanitis (17.3%), eczema (12.8%), lichen planus (7.3%), psoriasis (7.2%) and benign lesions (5.5%). The commonest presenting symptoms were genital rash (43%), genital soreness, pain or burning (17.5%), and penile lesions (15.7%). Lichen sclerosus and all forms of balanitis were more common in uncircumcised patients, whereas lichen planus was more common in circumcised males. Short-term outcome was excellent, with 11.5% of patients being reassured and discharged on their first visit, and after 6 months 58% of all patients were clear and 12% had improved. Only 4.5% reported no improvement in symptoms. Diagnostic biopsy demonstrated malignant or premalignant lesions in nearly a fifth of those having a procedure. Close working with urological and genitourinary medicine colleagues is important to manage the various aspects of male health. © 2017 British Association of Dermatologists.

46,XX-maleness affects 1 in 20 000 live male newborns resulting in infertility and hypergonadotrophic hypogonadism. Although the phenotypes of XX-males have been well described, the molecular nature of the X chromosomes remains elusive. We assessed the X inactivation status by DNA methylation analysis of four informative loci and compared those to Klinefelter syndrome (KS) and Turner syndrome. Patient cohort consisted of ten sex-determining region of the Y (SRY+) XX-males, two (SRY-) XX-males, ten 47,XXY Klinefelter men, six 45,X Turner females and ten male and female control individuals each. Methylation analysis was carried out by bisulphite sequencing of DNA from peripheral blood lymphocytes analysing X-inactive-specific transcript (XIST), phosphoglycerate kinase 1 (PGK1), ferritin, heavy peptide-like 17 (FTHL17) and short stature homeobox (SHOX). XIST methylation was 18% in (SRY+) XX-males, and thus they were severely hypomethylated compared to (SRY-) XX-males (48%; P<0.01), Klinefelter men (44%; P<0.01) and female controls (47%; P<0.01). Turner females and male controls displayed a high degree of XIST methylation of 98 and 94% respectively. Methylation of PGK1, undergoing X inactivation, was not significantly reduced in (SRY+) XX-males compared to female controls in spite of severe XIST hypomethylation (51 vs 69%; P>0.05). FTHL17, escaping X inactivation, but undergoing cell-type-specific inactivation was similarly methylated in XX-males (89%), KS patients (87%) and female controls (90%). SHOX, an X inactivation escapee located in the pseudoautosomal region, displays similarly low degrees of methylation for XX-males (7%), KS patients (7%) and female controls (9%). XIST hypomethylation clearly distinguishes (SRY+) XX-males from Klinefelter men. It does not, however, impair appropriate epigenetic regulation of representative X-linked loci.

The aim of the present study was to find and compare the correlations between somatotype and some anthropological parameters in Bulgarian male patients with type 2 diabetes mellitus. Anthropometric measurements were taken from 165 male patients with type 2 diabetes mellitus. All patients were ethnic Bulgarians. They were divided into two age groups: a 40-60-year group (58 patients, mean age 52.05 ± 0.73 yrs), and a 61-80-year group (111 patients, mean age 68.02 ± 0.53 yrs). The controls were allocated into similar age-matched groups. Direct anthropometric measurements were body height and weight, biepicondylar breadth of the humerus and biepicondylar breadth of the femur. Circumferential measurements were taken from the relaxed and contracted upper arm, the forearm, the waist, the hip, the thigh and the medial calf. Skin folds were measured below the inferior angle of the scapula, above the X rib, above the crista iliaca, at the abdomen, triceps brachii, forearm, thigh and the medial calf. The components of human somatotype according to the criteria of Heath-Carter, body mass index (BMI) and waist-to-hip ratio (WHR) were calculated. We found very strong positive correlations (PC > 0.70) between BMI and the endomorphic and mesomorphic components of somatotype in 40-60-year-old male diabetic patients. The correlation between the endomorphic and mesomorphic components of somatotype and the anthropometric measurements characterizing the central accumulation of adipose tissue (waist circumference, hip circumference, WHR) was very strong positive (PC = 0.5-0.7). Male diabetic patients aged 61-80 years: we found a very strong positive correlation between endomorphic and mesomorphic components and BMI, a strong correlation between these components and the waist circumference, and a good correlation between the components and the circumferences of the waist and hip and WHR. In male patients with type 2 diabetes aged 40-60 years, the endomorphic and mesomorphic components

[The affective pathology in patients with adolescent bulimia nervosa].

Grachev, V V

To investigate affective pathology in patients with adolescent bulimia nervosa (BN) and to analyze comorbid mutual influences of these clinical entities. A sample consisted of 52 young female patients, aged from 13.9 to 17.4 years, who simultaneously meet ICD-10 criteria of F50.2 - typical BN and F30-F39 - mood disorders. The Eating Attitudes Test (EAT-26) and the Beck Depression Inventory were used for psychometric assessment. Duration of follow-up ranged from 1 to 7 years. The common forms of affective disorders comorbid with adolescent BN were dysthymia and bipolar affective disorder (BAD) type II. Less often BN manifested in association with psychogenic endoform depressions. And the less typical was comorbidity of BN with endogenous recurrent unipolar depression. The normalization of mood and transition depression to hypomania contributed to the remission of eating disorders. Worst clinical and social outcome was detected in patients with long-term persistent hypothymia caused by dysthymia or protracted depressive episodes of recurrent depressive disorder. A more favorable outcome was seen in patients with alternation of depression and hypomania in the structure of the BAD type II and the best outcome in patients with single episode of psychogenic endoform depression.

To evaluate plasma vitamin D and cross-linked C-telopeptides of type I (CTx-I) and type II (CTx-II) collagen concentrations in males with lumbar intervertebral disc degeneration (IVD) compared to healthy controls. Improved knowledge might suggest to optimize the vitamin D status of IVD patients and contribute to clarify mechanisms of cartilage degradation. 79 Italian males with lumbar IVD assessed by Magnetic Resonance Imaging (MRI) and 79 age, sex and BMI-matched healthy controls were enrolled. Plasma 25hydroxyvitamin D (25(OH)D), CTx-I and CTx-II were measured by immunoassays. Circannual seasonality, correlation between biomarkers concentrations and clinical variables were assessed. Overall subjects 25(OH)D and CTx-II showed month rhythmicity with acrophase in August/September and October/November, and nadir in February/March and April/May, respectively. An inverse correlation between 25(OH)D and CTx-I, and a direct correlation between CTx-II and CTx-I were observed. IVD patients, particularly with osteochondrosis, showed higher CTx-II than healthy controls. Month of sampling may affect plasma 25(OH)D and CTx-II concentrations. The correlation between CTx-I and CTx-II suggests an interplay between the osteo-cartilaginous endplate and the fibro-cartilaginous disc. The results of this study highlighted that osteochondrosis associates with increased cartilaginous catabolism. Vitamin D supplementation seems more necessary in winter for lumbar IVD patients.

To describe the clinical phenotypes of four unrelated Japanese male patients with juvenile retinoschisis and to investigate occurrences of mutations in the RS1 gene. Observational case series and experimental study. Fundus examinations, fluorescein angiography, and single-flash electroretinography (ERG) were carried out. In one patient, optical coherence tomography (OCT) was performed. The coding regions of the RS1 gene that encodes retinoschisin were amplified by polymerase chain reaction (PCR). The PCR products were purified and directly sequenced. The four affected patients showed cystoid- or wheel-like foveal changes with a little or no fluorescein leakage and negative b-wave patterns in both eyes. The OCT images of foveal retinoschisis disclosed that splitting occurs in the putative fibers of Henle. In three patients, we identified three different missense mutations (p.S73P, p.Y89C, p.R209C) in the functionally important discoidin domain of the RS1 gene. The p.S73P mutation has not been previously reported. In contrast, no nucleotide substitutions were detected in the fourth patient whose parents were unrelated and asymptomatic. No other member of this family for three generations has had juvenile retinoschisis. Because serine 73 is conserved in the mouse ortholog and other discoidin proteins, the proline 73 allele is therefore very likely to encode a defective retinoschisin. Although the inheritance pattern is uncertain in the patient without the RS1 mutation, the clinical and ERG findings were indistinguishable from those of patients with RS1 mutations. This finding points to the genetic heterogeneity of juvenile retinoschisis.

This study investigated whether the previously observed association of pedophilia with lower IQs is an artifact of heterogeneity in referral source. The subjects were 832 adult male patients referred to a specialty clinic for evaluation of their sexual behavior. The patients' erotic preferences for prepubescent, pubescent, or adult partners were assessed with phallometric testing. Full scale IQ was estimated using six subtests from the WAIS-R. The results showed that the relations between pedophilia and lower IQ, lesser education, and increased rates of non-right-handedness were the same in homogeneous groups referred by lawyers or parole and probation officers as they were in a heterogeneous group referred by a miscellany of other sources. Those results, along with secondary analyses in the study, supported the conclusion that the relation between pedophilia and cognitive function is genuine and not artifactual. The findings were interpreted as evidence for the hypothesis that neurodevelopmental perturbations increase the risk of pedophilia in males.

Changes in hormone blood levels during the acute phase of traumatic brain injury (TBI) have been described in the literature. The objective was to investigate the association among several hormones plasma levels in the acute phase of severe TBI and the hospital mortality rate of male patients. The independent association among plasma levels of TSH, LH, FSH, GH, free T4, cortisol, IGF-1 and total testosterone was measured 10 hours and 30 hours after severe TBI and the hospital mortality of 60 consecutive male patients was evaluated. At least one hormonal level abnormality was demonstrated in 3.6-73.1% of patients. The multiple logistic regressions showed a trend for an independent association among hospital mortality and normal or elevated LH levels measured at 10 hours (OR = 3.7, 95% CI = 0.8-16.3, p = 0.08) and 30 hours (OR = 3.9, 95% CI = 0.9-16.7, p = 0.06). Admission with abnormal pupils and a lower Glasgow Coma Score also were independently associated with hospital mortality. The hormonal changes are frequent in the acute phase of severe TBI. The hormones plasma levels, excepting the LH, are not highly consistent with the hospital mortality of male patients.

To compare the level of testosterone between type-2 diabetes mellitus (T2DM) patients and healthy controls and to investigate the status of hypogonadism and the influence of hypopgonadism on the quality of life. We collected serum total testosterone (TT), free testosterone (FT), sex hormone-binding globulin (SHBG), and other clinical data from 166 T2DM patients aged over 30 years and 186 age-matched healthy controls. We investigated the quality of life (QoL) of the two groups of subjects using the questionnaires of Androgen Deficiency in Aging Males (ADAM), Aging Male Symptoms (AMS), 36-Item Short-Form Health Survey (SF-36), and Special Quality of Life for Diabetes Mellitus (DSQL). The level of calculated FT (cFT) was remarkably lower in the T2DM patients than in the healthy controls (P<0.05), but no statistically significant differences were observed between the two groups in the levels of TT, bio-available testosterone (Bio-T), and SHBG. The T2DM males with hypogonadism showed significant differences from those without in age, height, systolic blood pressure, and creatinine (P<0.05). Based on the criteria of cFT <0.3 nmol/L and AMS score ≥27, the incidence rate of hypogonadism was 51.81% in the T2DM patients, 31.58% in the 30－39 yr group, 32.50% in the 40－49 yr group, 50% in the 50－59 yr group, 69.23% in the 60－69 yr group, and 77.27% in the ≥70 yr group, elevated by 77.4% with the increase of 10 years of age (OR = 1.774, P<0.001). The AMS score was significantly correlated with the scores of DSQL (r = 0.557, P<0.001) and SF-36 (r = －0.739, P<0.001) in the T2DM patients. T2DM patients have lower levels of cFT than healthy men, accompanied with a higher incidence of hypogonadism. Age is a main risk factor of hypogonadism. Severer testosterone deficiency symptoms are associated with lower scores of QoL in T2DM males.

The study aimed to describe the medical, psychiatric, and cultural features of adolescent males with an eating disorder (ED). This retrospective evaluation took place at Hacettepe University, İhsan Doğramacı Children's Hospital, Ankara, Turkey, and covered a 4-year period between 2010 and 2013. Sixty adolescents were diagnosed with an ED during this period, 47 (78.3%) were females and 13 were males (21.7%) male. All 13 male patients who met full criteria for an ED according to the DSM criteria were included. Medical and psychiatric records of male patients treated for an ED were re-evaluated. The most striking finding of the study was that the female to male ratio became 3.6:1, with the increasing number of male adolescents with an ED. In our study, medical findings and complications of males with ED were similar to those seen in females. However, the most predominant gender difference was the co occurrence of a comorbid physical or mental illness. It is imperative to raise awareness of EDs in males. Although the medical findings of the study suggest that male and female adolescents with EDs are clinically similar to each other, the understanding of certain gender-specific risk factors shown in our study, such as a medical illness and/or obesity and co-morbid psychiatric diagnosis, are essential in raising suspicion. Further studies that especially evaluate cultural and social factors that affect parenting styles for boys are important in addessing possible risk factors for the development of EDs in males within different societies.

Fabry Disease (FD), an X linked lysosomal storage disease due to pathogenic α-galactosidase A ( GLA ) mutations, results in two major subtypes, the early-onset Type 1 'Classic' and the Type 2 'Later-Onset' phenotypes. To identify previously unrecognised patients, investigators screened cardiac, renal and stroke clinics by enzyme assays. However, some screening studies did not perform confirmatory GLA mutation analyses, and many included recently recognised 'benign/likely-benign' variants, thereby inflating prevalence estimates. Online databases were searched for all FD screening studies in high-risk clinics (1995-2017). Studies reporting GLA mutations were re-analysed for pathogenic mutations, sex and phenotype. Phenotype-specific and sex-specific prevalence rates were determined. Of 67 studies, 63 that screened 51363patients (33943M and 17420F) and provided GLA mutations were reanalysed for disease-causing mutations. Of reported GLA mutations, benign variants occurred in 47.9% of males and 74.1% of females. The following were the revised prevalence estimates: among 36820 (23954M and 12866F) haemodialysis screenees, 0.21% males and 0.15% females; among 3074 (2031M and 1043F) renal transplant screenees, 0.25% males and no females; among 5491 (4054M and 1437F) cardiac screenees, 0.94% males and 0.90% females; and among 5978 (3904M and 2074F) stroke screenees, 0.13% males and 0.14% females. Among male and female screenees with pathogenic mutations, the type 1 Classic phenotype was predominant (~60%), except more male cardiac patients (75%) had type 2 Later-Onset phenotype. Compared with previous findings, reanalysis of 63 studies increased the screenee numbers (~3.4-fold), eliminated 20 benign/likely benign variants, and provided more accurate sex-specific and phenotype-specific prevalence estimates, ranging from ~0.13% of stroke to ~0.9% of cardiac male or female screenees. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article

The western lowland gorilla (Gorilla gorilla gorilla) is one of the most sexually dimorphic primate species. Mature males are twice the size of females and have grey fur on their backs and a fibrous, adipose crest on their heads. Such traits are likely to have evolved by sexual selection, either because they confer advantages during male-male fights or because females prefer males with more dimorphic traits. We developed photogrammetric methods for distance collection of morphological data from silverback males frequenting the Lokoué forest clearing in Odzala-Kokoua National Park, Republic of the Congo. Body length, head-crest size, musculature development, and extent of the grey color on the back were assessed in 87 nonbreeding and breeding mature males. Behavioral data were also collected during 312 male-male encounters involving 67 mature males in order to estimate their level of aggressiveness. The number of females belonging to a mature male positively correlated with the male crest size, body length, and musculature. Whereas morphological variables did not significantly affect the intensity of male-male encounters, the number of females attending male-male encounters strongly affected the number of agonistic displays by the two males. We discuss the mechanisms through which males with more exaggerated traits could obtain a mating advantage, namely male-male fights or female mate choice. (c) 2007 Wiley-Liss, Inc.

There is a growing interest in the treatment of late-onset hypogonadism, another name for the study of testosterone deficiency in an older age group. Initial attempts at testosterone replacement have also brought attention to the possible adverse effects on the patients' cardiovascular risk factors and their prostate health. The "female" hormone estradiol is no longer considered as the feminizing hormone, as it has been identified to have an effect on the sexual and general well-being of adult males. Urologists and endocrinologists alike have started to pay attention to the serum T/E 2 (testosterone : estradiol) ratio that appears to be more important than the respective individual hormonal levels. Therein lies the possible role of aromatase inhibitors (AIs) in restoring the normal balance of serum testosterone and estradiol levels for the adequate treatment of late-onset hypogonadism, while limiting the potential adverse effects. Currently, other established clinical indications of AIs include the treatment of breast cancer in female patients and developmental growth problems in pediatric patients. This review evaluates the role of AIs as a treatment option for late-onset hypogonadism and the evidence for its other clinical uses in men, including its possible adverse effects. A literature review was performed with regards to the use of aromatase inhibitors in adult males, the role of estrogens in adult males, as well as adverse effect of AIs on bone health in adult males. To evaluate the evidence for the use of AIs in adult males to treat late-onset hypogonadism, obesity-related hypogonadotropic hypogonadism, gynecomastia, and male subfertility. To evaluate the evidence for the possible adverse effects on the bone health of adult males with the use of AIs. Currently there is no literature to recommend the use of AIs in adult males to treat late-onset hypogonadism, obesity-related hypogonadotropic hypogonadism, gynecomastia, or male subfertility, although some

Objective: To explore the clinical manifestations and molecular features of 46, XX male syndrome. Method: The clinical and molecular data of five 46, XX male syndrome cases treated in the Department of Pediatrics of Shanghai Ruijin Hospital form August 2010 to August 2014 were retrospectively analyzed. Result: The five patients were all sociopsychologically males and came to hospital respectively for short stature, ambiguous genitalia or gynecomastia. They were all below the normal male's average height, and their karyotype was all 46, XX. One case in five was verified as sex determining region of Y chromosome (SRY gene) positive revealed no abnormality in their external genitalia. He had short stature since childhood, whose SRY gene fragments were shown by FISH transferred to the ends of X chromosome. Three cases in four were SRY gene negative with ambiguous genitalia of cryptorchidism and testicular dysplasia to different degrees. The copy number variations of SOX9 gene was found in one case, the loss of heterozygosity area in DHH gene of one case. Another SRY gene negative patient who had normal male external genitalia, came to the hospital due to puberty gynecomastia, that of SOX9 gene and its upstream gene both increased. Conclusion: The main clinical characteristics of 46, XX male syndrome are male phenotype, 46, XX karyotype, gonad of testis or ovotestis and no uterus. In addition, short stature, ambiguous genitalia or gynecomastia can be one reason for hospital visits. SRY gene translocation, SOX9 gene and its upstream gene copy number increase all can lead to 46, XX male syndrome. The cause of some may play an important role in 46, XX male syndrome, but has not yet been determined.

In most cases, about the voice of the patient with female-to-male/gender identity disorder (FTM/GID), hormone therapy makes the voice low-pitched. In success cases, there is no need for phonosurgery. However, hormone therapy is not effective in some cases. We perform type 3 thyroplasty in these cases. Hormone therapy was started in 2008 but did not lower the speaking fundamental frequencies (SFFs). We therefore performed TP3 under local anesthesia. In our case, the SFF at the first visit was 146 Hz. The postoperative SFF was 110 Hz. TP3 was performed under local anesthesia in a patient with FTM/GID in whom hormone therapy proved ineffective. With successful conversion to a lower-pitched voice, the patient could begin to live daily life as a male. QOL improved significantly with TP3. If hormone therapy proves ineffective, TP3 may be selected as an optional treatment and appears to show few surgical complications and was, in this case, a very effective treatment.

Objective The nutritional status of chronic obstructive pulmonary disease (COPD) patients is associated with their exercise capacity. In the present study, we have explored the relationship between nutritional risk and exercise capacity in severe male COPD patients. Methods A total of 58 severe COPD male patients were enrolled in this study. The patients were assigned to no nutritional risk group (n=33) and nutritional risk group (n=25) according to the Nutritional Risk Screening (NRS, 2002) criteria. Blood gas analysis, conventional pulmonary function testing, and cardiopulmonary exercise testing were performed on all the patients. Results Results showed that the weight and BMI of the patients in the nutritional risk group were significantly lower than in the no nutritional risk group (P<0.05). The pulmonary diffusing capacity for carbon monoxide of the no nutritional risk group was significantly higher than that of the nutritional risk group (P<0.05). Besides, the peak VO2 (peak oxygen uptake), peak O2 pulse (peak oxygen pulse), and peak load of the nutritional risk group were significantly lower than those of the no nutritional risk group (P<0.05) and there were significantly negative correlations between the NRS score and peak VO2, peak O2 pulse, or peak load (r<0, P<0.05). Conclusion The association between exercise capacity and nutritional risk based on NRS 2002 in severe COPD male patients is supported by these results of this study. PMID:26150712

Hepatic lipase (HL) deficiency is a rare genetic disorder that has been associated with premature atherosclerosis despite high plasma high-density lipoprotein (HDL) cholesterol concentrations in the affected individuals. The authors describe the clinical and biochemical features of HL deficiency in a young male of Middle-Eastern-Arabic origin. This is the first report of cholesterol ester transfer protein (CETP) activity and mass in HL deficiency in a patient from this ethnic group. While the CETP mass was high, its activity was low, a discrepancy likely due to the abnormal composition of patient's HDL particles.

Introduction Current trends in dementia research focus on early and accurate diagnosis. In clinical practice however, this is not always possible, as multiple underlying pathologies produce mixed dementia syndromes. Furthermore, patients with severe dementia are often underestimated. Case presentation We present a case of a 71 year old Caucasian male with severe Alzheimer's Disease, bedridden and fully dependent in activities of everyday living, whose general cognitive function is almost intact. We emphasize on the diverse underlying pathologies contributing to this intriguing clinical presentation and to diagnostic uncertainty. Conclusion Understanding the complexity of the dementia process in every patient using a multidimensional approach, contributes to more rational management strategies and finally to high quality care for patients and caregivers.

Proliferation activity has already been established as a prognostic marker or as a marker for anticancer drug sensitivity. In gastric cancer, however, the prognostic significance of proliferation activity is still being debated. Several studies evaluating proliferation activity using Ki-67 have shown controversial results in terms of the relationship between proliferation activity and overall survival (OS) or drug sensitivity in gastric cancer patients. Because cytoskeleton-associated protein 2 (CKAP2) staining has recently been introduced as a marker of proliferation activity, we analyzed 437 gastric cancer tissues through CKAP2 immunohistochemistry, and we evaluated the chromatin CKAP2-positive cell count (CPCC) for proliferation activity. Although the CPCC did not show any significant correlation with OS in the male, female or total number of cases, it did show a significant correlation in the T1 or T2 male patient subgroup, according to log-rank tests (P=0.001) and univariate analysis (P=0.045). Additionally, multivariate analysis with the Cox proportional hazard regression model showed a significant correlation between the CPCC and OS (P=0.039) for the co-variables of age, gender, T stage, N stage, histology, tumor location, tumor size and adjuvant chemotherapy. In male gastric cancer cell lines, faster-growing cancer cells showed higher sensitivity to cisplatin than slow-growing cells. Thus our study indicates that CPCC-measured proliferation activity demonstrates a significantly worse prognosis in T1 or T2 male gastric cancer patients. The CPCC will help to more precisely classify gastric cancer patients and to select excellent candidates for adjuvant chemotherapy, which in turn will facilitate further clinical chemotherapeutic trials.

Turn it off! the effects of exposure to male-male erotic imagery on heterosexuals' attitudes toward gay men.

Despite the recent proliferation of lesbian, gay, and bisexual (LGB) thematic content in U.S. media, there have been relatively few empirical investigations examining its impact on heterosexuals' attitudes toward LGB individuals. This study examined the effect of one type of content, male-male homoerotic imagery, on male and female heterosexuals' attitudes toward, stereotypes about, and affective reactions to gay men. One hundred ninety-eight undergraduate students were assigned to either a male-male or male-female erotica condition, and their corresponding attitudes toward gay men were assessed. Results revealed that the effect of erotic imagery (male-male vs. male-female) on participants' stereotype and affect scores differed for men and women at varying levels of sexual anxiety. The implications of these findings are discussed in light of the literature on exposure to erotic imagery and attitudes toward gay men. In particular, the study highlights the need for additional research that acknowledges within-gender heterogeneity with respect to antigay attitude valence, extremity, and function.

To evaluate actual post-pubertal penile size and factors affecting it in hypospadias patients, we retrospectively reviewed medical charts. Hypospadias patients whose external genitalia were categorized into Tanner stage 5, and whose stretched penile length was evaluated at 15 years old or older from April 2008 to April 2015, were enrolled in the present study. Stretched penile length was measured by a single examiner. Actual post-pubertal stretched penile length and factors affecting the post-pubertal stretched penile length were estimated. Statistical analysis was performed using Mann-Whitney U test and univariate and multivariate linear regression models for the determination of independent factors. Thirty patients met the inclusion criteria. Median age at evaluation was 17.2 years. Thirteen and 17 had mild and severe hypospadias, respectively. Endocrinological abnormality was identified in 5. Multivariate analysis showed that the severity of hypospadias and endocrinological abnormality were significant factors affecting stretched penile length. Stretched penile length in 25 patients without endocrinological abnormality was significantly longer than that in those with endocrinological abnormality (p = 0.036). Among patients without endocrinological abnormality, stretched penile length in 13 with severe hypospadias was significantly shorter than that in 12 with mild hypospadias (p = 0.004). While the severity of hypospadias and endocrinological abnormality at post-pubertal evaluation were factors affecting post-pubertal penile size, stretched penile length in patients with severe hypospadias was shorter even in cases without endocrinological abnormality. These results suggest that severe hypospadias is not only a disorder of urethral development, but also a disorder of penile development.

The aim of this research was to examine the relationship between therapist interventions and patient affect responses in Short-Term Dynamic Psychotherapy (STDP). The Affect Experiencing subscale from the Achievement of Therapeutic Objectives Scale (ATOS) was adapted to measure individual immediate affect experiencing (I-AES) responses in relation to therapist interventions coded within the preceding speaking turn, using the Psychotherapy Interaction Coding (PIC) system. A hierarchical linear modelling procedure was used to assess the change in affect experiencing and the relationship between affect experiencing and therapist interventions within and across segments of therapy. Process data was taken from six STDP cases; in total 24 hours of video-taped sessions were examined. Therapist interventions were found to account for a statistically significant amount of variance in immediate affect experiencing. Higher levels of immediate affect experiencing followed the therapist's use of Confrontation, Clarification and Support compared to Questions, Self-disclosure and Information interventions. Therapist Confrontation interventions that attempted to direct pressure towards either the visceral experience of affect or a patient's defences against feelings led to the highest levels of immediate affect experiencing. The type of therapist intervention accounts for a small but significant amount of the variation observed in a patient's immediate emotional arousal. Empirical findings support clinical theory in STDP that suggests strategic verbal responses promote the achievement of this specific therapeutic objective.

Anti-müllerian hormone and sertoli cell function in paediatric male hypogonadism.

PubMed

Grinspon, Romina P; Rey, Rodolfo A

2010-01-01

In the prepubertal male, Sertoli cells are the most active testicular cell population. Without stimulation tests, prepubertal hypogonadism can only be evidenced if Sertoli cell function is assessed. Anti-müllerian hormone (AMH) is a distinctive marker of the prepubertal Sertoli cell. Serum AMH is high from fetal life until puberty. In postnatal life, AMH testicular production is stimulated by FSH and potently inhibited by androgens. In anorchid patients, AMH is undetectable. In prepubertal males with fetal- or childhood-onset primary or central hypogonadism affecting the whole gonad, serum AMH is low. Conversely, when hypogonadism only affects Leydig cells (i.e., LH/human chorionic gonadotrophin receptor or steroidogenic enzyme defects), serum AMH is normal/high. AMH is also normal/high in patients with androgen insensitivity. In patients of pubertal age with central hypogonadism, AMH is low for Tanner stage - reflecting lack of FSH stimulus, - but high for age - reflecting lack of testosterone inhibitory effect. FSH treatment results in serum AMH rise, whereas human chorionic gonadotrophin treatment increases testosterone levels which inhibit AMH production. In conclusion, AMH determination is helpful in assessing gonadal function, without need for stimulation tests, and orientates the aetiological diagnosis of paediatric male hypogonadism. Furthermore, serum AMH is an excellent marker of FSH and androgen action in the testis. Copyright 2010 S. Karger AG, Basel.

The goal of our study was to evaluate findings in mammography and sonography in male patients with pathohistologically proven diseases of the breast. Mammographies and sonographies, which were obtained in 41 male patients in a 6-year period, were retrospectively evaluated in accordance with the BI-RADS(R) classification. Histologically 13 carcinomas, 21 gynecomastias, 3 pseudogynecomastias, 2 epithelial inclusion cysts and 2 other benign lesions were diagnosed. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of mammography in differentiation of benign versus malignant disease were 92 %, 89 %, 80 %, 96 % and 90 %, respectively. Additional sonography did not change these results. However, sonography increased diagnostic confidence in 18.2 % (2/11) of suspicious lesions. In our study the invasive ductal carcinoma of male patients was a predominantly lobulated, ill-defined lesion in mammography and sonography. The differentiation of carcinoma to pseudogynecomastia and diffuse or dendritic gynecomastia was securely feasible. However, we could not reliably distinguish between carcinoma and some benign mass lesions. In cases of mammographically diagnosed masses or unclear mammography, additional sonography should be performed to increase the diagnostic confidence.

Traumatic brain injury (TBI) is a worldwide core public health problem affecting mostly young male subjects. An alarming increase in incidence has turned TBI into a leading cause of morbidity and mortality in young adults as well as a tremendous resource burden on the health and welfare sector. Hormone dysfunction is highly prevalent during the acute phase of severe TBI. In particular, investigation of the luteinizing hormone (LH) and testosterone levels during the acute phase of severe TBI in male has identified a high incidence of low testosterone levels in male patients (36.5–100%) but the prognostic significance of which remains controversial. Two independent studies showed that normal or elevated levels of LH levels earlier during hospitalization are significantly associated with higher mortality/morbidity. The association between LH levels and prognosis was independent of other predictive variables such as neuroimaging, admission Glasgow coma scale, and pupillary reaction. The possible mechanisms underlying this association and further research directions in this field are discussed. Overall, current data suggest that LH levels during the acute phase of TBI might contribute to accurate prognostication and further prospective multicentric studies are required to develop more sophisticated predictive models incorporating biomarkers such as LH in the quest for accurate outcome prediction following TBI. Moreover, the potential therapeutic benefits of modulating LH during the acute phase of TBI warrant investigation. PMID:29487565

Alcohol affects brain functional connectivity and its coupling with behavior: greater effects in male heavy drinkers.

Acute and chronic alcohol exposure significantly affect behavior but the underlying neurobiological mechanisms are still poorly understood. Here, we used functional connectivity density (FCD) mapping to study alcohol-related changes in resting brain activity and their association with behavior. Heavy drinkers (HD, N=16, 16 males) and normal controls (NM, N=24, 14 males) were tested after placebo and after acute alcohol administration. Group comparisons showed that NM had higher FCD in visual and prefrontal cortices, default mode network regions and thalamus, while HD had higher FCD in cerebellum. Acute alcohol significantly increased FCD within the thalamus, impaired cognitive and motor functions, and affected self-reports of mood/drug effects in both groups. Partial least squares regression showed that alcohol-induced changes in mood/drug effects were associated with changes in thalamic FCD in both groups. Disruptions in motor function were associated with increases in cerebellar FCD in NM and thalamus FCD in HD. Alcohol-induced declines in cognitive performance were associated with connectivity increases in visual cortex and thalamus in NM, but in HD, increases in precuneus FCD were associated with improved cognitive performance. Acute alcohol reduced 'neurocognitive coupling', the association between behavioral performance and FCD (indexing brain activity), an effect that was accentuated in HD compared with NM. Findings suggest that reduced cortical connectivity in HD contribute to decline in cognitive abilities associated with heavy alcohol consumption, whereas increased cerebellar connectivity in HD may have compensatory effects on behavioral performance. The results reveal how drinking history alters the association between brain FCD and individual differences in behavioral performance.

Factors affecting patients' online health information-seeking behaviours: The role of the Patient Health Engagement (PHE) Model.

To identify the variables affecting patients' online health information-seeking behaviours by examining the relationships between patient participation in their healthcare and online health information-seeking behaviours. A cross-sectional survey of Italian chronic patients (N=352) was conducted on patient's online health information-seeking behaviours and patient participation-related variables. Structural equation modeling analysis was conducted to test the hypothesis. This study showed how the healthcare professionals' ability to support chronic patients' autonomy affect patients' participation in their healthcare and patient's online health information-seeking behaviours. However, results do not confirm that the frequency of patients' online health-information seeking behavior has an impact on their adherence to medical prescriptions. Assuming a psychosocial perspective, we have discussed how patients' engagement - conceived as the level of their emotional elaboration of the health condition - affects the patients' ability to search for and manage online health information. To improve the effectiveness of patients' online health information-seeking behaviours and to enhance the effectiveness of technological interventions in this field, healthcare providers should target assessing and improving patient engagement and patient empowerment in their healthcare. It is important that health professionals acknowledge patients' online health information-seeking behaviours that they discuss the information offered by patients and guide them to reliable and accurate web sources.

MECHANISMS IN ENDOCRINOLOGY: Aberrations of the X chromosome as cause of male infertility.

PubMed

Röpke, Albrecht; Tüttelmann, Frank

2017-11-01

Male infertility is most commonly caused by spermatogenetic failure, clinically noted as oligo- or a-zoospermia. Today, in approximately 20% of azoospermic patients, a causal genetic defect can be identified. The most frequent genetic causes of azoospermia (or severe oligozoospermia) are Klinefelter syndrome (47,XXY), structural chromosomal abnormalities and Y-chromosomal microdeletions. Consistent with Ohno's law, the human X chromosome is the most stable of all the chromosomes, but contrary to Ohno's law, the X chromosome is loaded with regions of acquired, rapidly evolving genes, which are of special interest because they are predominantly expressed in the testis. Therefore, it is not surprising that the X chromosome, considered as the female counterpart of the male-associated Y chromosome, may actually play an essential role in male infertility and sperm production. This is supported by the recent description of a significantly increased copy number variation (CNV) burden on both sex chromosomes in infertile men and point mutations in X-chromosomal genes responsible for male infertility. Thus, the X chromosome seems to be frequently affected in infertile male patients. Four principal X-chromosomal aberrations have been identified so far: (1) aneuploidy of the X chromosome as found in Klinefelter syndrome (47,XXY or mosaicism for additional X chromosomes). (2) Translocations involving the X chromosome, e.g. nonsyndromic 46,XX testicular disorders of sex development (XX-male syndrome) or X-autosome translocations. (3) CNVs affecting the X chromosome. (4) Point mutations disrupting X-chromosomal genes. All these are reviewed herein and assessed concerning their importance for the clinical routine diagnostic workup of the infertile male as well as their potential to shape research on spermatogenic failure in the next years. © 2017 European Society of Endocrinology.

This study focuses on the role of male-male vocal communication in the reproductive repertoire of the South African clawed frog, Xenopus laevis . Six male and two female call types were recorded from native ponds in the environs of Cape Town, South Africa. These include all call types previously recorded in the laboratory as well as one previously unidentified male call: chirping. The amount of calling and the number of call types increased as the breeding season progressed. Laboratory recordings indicated that all six male call types were directed to males; three of these were directed to both sexes and three were directed exclusively to males. Both female call types were directed exclusively to males. The predominant call type, in both field and laboratory recordings, was the male advertisement call. Sexual state affected male vocal behaviour. Male pairs in which at least one male was sexually active (gonadotropin injected) produced all call types, whereas pairs of uninjected males rarely called. Some call types were strongly associated with a specific behaviour and others were not. Clasped males always growled and clasping males typically produced amplectant calls or chirps; males not engaged in clasping most frequently advertised. The amount of advertising produced by one male was profoundly affected by the presence of another male. Pairing two sexually active males resulted in suppression of advertisement calling in one; suppression was released when males were isolated after pairing. Vocal dominance was achieved even in the absence of physical contact (clasping). We suggest that X. laevis males gain a reproductive advantage by competing for advertisement privileges and by vocally suppressing neighbouring males.

The number of total cosmetic procedures performed yearly has increased by more than 274% between 1997 and 2014, according to the American Society for Aesthetic Plastic Surgery. However, the vast majority of plastic surgery procedures are still targeted toward women, with little attention toward men. This study sought to quantify the extent of gender discrepancies observed in online plastic surgery marketing in this country. For the 48 contiguous United States, a systematic Google (Mountain View, CA) search was performed for "[state] plastic surgeon." The first 10 solo or group practice websites in each state were analyzed for the gender of the first 10 images featured, presence of a male services section, and which procedures were offered to men. The results were statistically analyzed using SPSS Software (IBM Corporation, Armonk, NY). A total of 453 websites were analyzed, as 5 states did not have 10 unique solo or group practice websites. Of the 4239 images reviewed, 94.1% were of females, 5.0% were of males, and 0.9% were of a male and female together. A male services page was present in 22% of websites. The most common procedures marketed toward men were gynecomastia reduction (58%), liposuction (17%), blepharoplasty (13%), and facelift (10%). Less than 10% of all websites offered other procedures to males, with a total of 15 other aesthetic procedures identified. Many plastic surgeons choose to ignore or minimize male patients in their online marketing efforts. However, as the number of men seeking cosmetic procedures continues to grow, plastic surgeons will benefit from incorporating male patients into their practice model. © 2015 The American Society for Aesthetic Plastic Surgery, Inc.

To determine the factors involved in violent behavior in patients with bipolar disorder (BD) and to investigate the relationship between violence and substance use disorder (SUD). A sample of 100 male inpatients diagnosed with BD type I who were experiencing a current mood episode participated in the study. Violent behavior was defined as physical aggression against others. All patients were evaluated using the Young Mania Rating Scale (YMRS), Hamilton Depression Rating Scale (HDRS), Positive and Negative Syndrome Scale-positive subscale (PANSS-p), Barratt Impulsivity Scale-11 (BIS-11), Buss-Perry Aggression Questionnaire (BPAQ) and Overt Aggression Scale (OAS). Lifetime SUD and current use of substances were evaluated. Logistic regression analysis was conducted to predict violent behavior. Current substance use (CSU) rather than lifetime SUD was found to be related to violent behavior in patients with BD, and CSU was associated with a threefold increase in the risk of violence. The rate of lifetime SUD in our sample was 59%, and the rate of CSU was 39%. The most commonly abused substances were cannabis and alcohol, followed by synthetic cannabinoids, in both groups of patients with lifetime SUD and CSU. Individuals abusing any substance were more likely to have a criminal record and history of incarceration than other patients. One of the most significant risk factors for violence was a previous history of violent behavior. The sample was limited to male patients. Data on some participants' recent substance use from standard urine analysis was not obtained. The data on the use of synthetic cannabinoids was obtained from patients and their families owing to the lack of equipment for detecting synthetic cannabinoids using laboratory analysis. CSU appears to be a significant predictive factor in violent behavior in male patients. Further investigation of co-occurrence of violence with CSU and improvement in treatment strategies might reduce or prevent violence in

Factors that affect the flow of patients through triage.

To use observational methods to objectively evaluate the organisation of triage and what issues may affect the effectiveness of the process. A two-phase study comprising observation of 16 h of triage in a London hospital emergency department and interviews with the triage staff to build a qualitative task analysis and study protocol for phase 2; observation and timing in triage for 1870 min including 257 patients and for 16 different members of the triage staff. No significant difference was found between grades of staff for the average triage time or the fraction of time absent from triage. In all, 67% of the time spent absent from triage was due to escorting patients into the department. The average time a patient waited in the reception before triage was 13 min 34 s; the average length of time to triage for a patient was 4 min 17 s. A significant increase in triage time was found when patients were triaged to a specialty, expected by a specialty, or were actively "seen and treated" in triage. Protocols to prioritise patients with potentially serious conditions to the front of the queue had a significantly positive effect on their waiting time. Supplementary tasks and distractions had varying effects on the timely assessment and triage of patients. The human factors method is applicable to the triage process and can identify key factors that affect the throughput at triage. Referring a patient to a specialty at triage affects significantly the triage workload; hence, alternative methods or management should be suggested. The decision to offer active treatment at triage increases the time taken, and should be based on clinical criteria and the workload determined by staffing levels. The proportion of time absent from triage could be markedly improved by support from porters or other non-qualified staff, as well as by proceduralised handovers from triage to the main clinical area. Triage productivity could be improved by all staff by becoming aware of the effect of

Male pattern hair loss is widespread around the world. Its prevalence indicates the importance of finding the best treatment modalities. This study evaluates the efficacy and safety of minoxidil 5% topical foam in male pattern hair loss treatment and patient satisfaction. This study was a before-and-after trial on 17 male patients with male pattern hair loss. Subjects were instructed to apply one capful (1 ml) of minoxidil 5% topical foam on the scalp daily for 6 months. Efficacy was assessed through hair counts, subject assessment, and global photographic review. Seventeen male volunteers were recruited, and three volunteers were withdrawn; 14 participated in the trial for 16 weeks, and 12 continued up to 24 weeks. The average hair count with a camera at week 16 (181.87 ± 52.42) and week 24 (194.58 ± 62.82) and with an eye count at week 16 (62.57 ± 15.28) and week 24 (69.91 ± 15.61) increased significantly compared to the baseline after intervention. This study confirmed that minoxidil 5% topical foam is a safe and effective treatment for MPHL. The effect of it is evident after 24 weeks of use.

The ways in which patients' requests for antidepressants affect physicians' prescribing behavior are poorly understood. To describe physicians' affective and cognitive responses to standardized patients' (SPs) requests for antidepressants, as well as the attitudinal and contextual factors influencing prescribing behavior. Focus group interviews and brief demographic questionnaires. Twenty-two primary care physicians in 6 focus groups; all had participated in a prior RCT of the influence of patients' requests on physicians' prescribing. Iterative review of interview transcripts, involving qualitative coding and thematic analysis. Physicians participating in the focus groups were frequently unaware of and denied the degree to which their thinking was biased by patient requests, but were able to recognize such biases after facilitated reflection. Common affective responses included annoyance and empathy. Common cognitive reactions resulted in further diagnostic inquiry or in acquiescing to the patient's demands to save time or build the patient-clinician relationship. Patients' requests for medication prompted the participants to err on the side of overtreating versus careful review of clinical indications. Lack of time and participants' attitudes--toward the role of the patient and the pharmaceutical ads--also influenced their responses, prompting them to interpret patient requests as diagnostic clues or opportunities for efficiency. This study provides a taxonomy of affective and cognitive responses to patients' requests for medications and the underlying attitudes and contextual factors influencing them. Improved capacity for moment-to-moment self-awareness during clinical reasoning processes may increase the appropriateness of prescribing.

Hepatic lipase (HL) deficiency is a rare genetic disorder that has been associated with premature atherosclerosis despite high plasma high-density lipoprotein (HDL) cholesterol concentrations in the affected individuals. The authors describe the clinical and biochemical features of HL deficiency in a young male of Middle-Eastern-Arabic origin. This is the first report of cholesterol ester transfer protein (CETP) activity and mass in HL deficiency in a patient from this ethnic group. While the CETP mass was high, its activity was low, a discrepancy likely due to the abnormal composition of patient's HDL particles. PMID:22798447

Patients respond more positively to physicians who focus on their ideal affect.

Previous findings suggest that patients choose physicians whose affective focus matches how they ideally want to feel (Sims et al., 2014). For instance, the more people wanted to feel excitement, the more likely they were to hypothetically choose a new physician who promoted excitement. What remains unknown is whether this match shapes how patients actually respond to physicians after being assigned to them (i.e., whether they adhere to physicians' recommendations more and evaluate physicians more positively). To this end, community adults reported their global ideal affect and actual affect (how they ideally want to feel and actually feel during a typical week, respectively), and were randomly assigned to receive health recommendations from either a physician who expressed and promoted high arousal positive states (HAP) (e.g., excitement), or one who expressed and promoted low arousal positive states (LAP) (e.g., calm). For the next 5 days, participants reported their daily adherence to the recommendations and their daily ideal and actual affect. At the end of the week, participants evaluated their physician. As predicted, the more participants wanted to feel HAP, the more they adhered to the "HAP-focused" physician's recommendations, and the more participants wanted to feel LAP, the more they adhered to the "LAP-focused" physician's recommendations. Participants also evaluated their physician more positively when his affective focus matched their ideal affect. Neither global nor daily actual affect systematically predicted how patients responded to their physicians. These findings suggest that patients respond better to physicians whose affective focus matches their ideal affect. (c) 2015 APA, all rights reserved).

2014-01-01

The doctor-patient relationship has been influenced by the appearance of physicians, and there is an association between a physician's physical appearance and the patients' initial perceptions of physician competence. This study aims to explore patients' preferences toward the attire of a male physician, and to examine if a physician's choice of uniform influences the degree of trust, confidence, and follow-up care among respondents. A cross-sectional survey conducted among patients of the Alwazarat family medicine center in Riyadh, Saudi Arabia. A self-administered questionnaire was completed by 300 patients (50% were male and 83.6% had received a secondary education; the mean age was 33.4 [10.1] years) in the Alwazarat family medicine center in Riyadh. The questionnaire was also customized for the local setting with the inclusion of photos of a male doctor in Saudi Arabian national costume, and 3 other dress styles (Western dress with white coat, scrubs with white coat, and scrubs only). Overall, across all questions regarding physician dress style preferences, participants significantly preferred Western dress (39.9%, P < .001), followed by Saudi national dress (26.3%), a scrub suit with a white coat (22.3%), and scrubs only (11.5%). Respondents reported that they were more likely to follow medical advice and would return for follow-up care if a physician wore Western dress. They were significantly more willing to share their social, sexual, and psychological problems with a physician wearing Saudi national dress (P < .001). The importance of a physician's appearance was ranked significantly higher by older patients (P=.002). Respondents were more likely to favor a physician wearing Western attire with a white coat. However, Saudi national dress, followed by Western dress, is the preferred attire when physicians are dealing with social, sexual, and psychological problems.

This is a qualitative study using a focus group approach, conducted to determine factors influencing adherence to osteoporosis medications among older adults. Thirty-two patients aged 65 to 85 years from the greater Boston area who were prescribed an osteoporosis medication, 11 general medicine physicians and 1 nurse practitioner were recruited from Boston based hospitals affiliated with a large healthcare system. Focus groups consisting of 6 to 8 subjects including males and females were held separately for providers and patients and conducted until thematic saturation was reached. Responses were obtained from patients and providers during the focus group interviews conducted by a trained focus group moderator. All interviews were audio taped and transcribed by a medical transcriptionist. According to patients, factors affecting adherence to osteoporosis drugs included lack of knowledge about osteoporosis, dissatisfaction with their doctor visits, side effects, and difficulty or failure to remember instructions for taking medications. Physicians reported lack of patient knowledge, structural barriers, medication side effects, and the inability to track patients’ adherence to their medications as barriers to adherence. This study identifies the extent of and reasons for non-adherence as perceived by patients and providers, and provides insights into strategies to modify treatment plans to address non-adherence. The results from this study were used to develop a RCT to conduct and evaluate patient and physician targeted interventions to improve adherence to osteoporosis medications and to examine cost effectiveness of alternative strategies.

The aim of the present study was to investigate the effect of intravenous C-peptide infusion on ocular blood flow in patients with type 1 diabetes under euglycemic conditions. The study was performed in a randomized, placebo-controlled, double-masked, two-way, crossover design in 10 type 1 diabetic patients. C-peptide was intravenously administered at two different dosages (dosage 1: 25 pmol . kg(-1) . min(-1) bolus followed by 5 pmol . kg(-1) . min(-1) continuous infusion; dosage 2: six times higher than dosage 1), each for 60 min. Physiologic saline solution was used as a control for C-peptide on a different study day. On both study days, euglycemic clamps were performed. To assess retinal blood flow, laser Doppler velocimetry (blood flow velocities) and retinal vessel analyzer (vessels diameters) measurements were performed. Laser interferometric measurements of fundus pulsation were used to assess pulsatile choroidal blood flow. Blood velocities in the ophthalmic artery were measured using color Doppler imaging. Eight patients (two female and six male) completed the study according to the protocol and without adverse events. One patient developed an anaphylactic reaction to C-peptide, which resolved without sequelae. The following results originate from the remaining eight subjects. Systemic hemodynamic parameters remained stable during both study days. Infusion of C-peptide did not affect any ocular hemodynamic parameter. The data of the present study indicate that exogenous C-peptide exerts no effect on ocular hemodynamic parameters in type 1 diabetic patients under euglycemic conditions. The maximum detectable change in these parameters was <25%.

The research was executed on 1433 patients, male (1055) and a female (378), of calendar age from 17 to 93 years with a various polyorgan somatic and psychoneurological pathology in remission. The polyorgan pathology worsens age-dependent indicators and increases the bioage of male and female patients. Thus sexual differences exist and practically disappear with the years. In men the polyorgan pathology makes negative influence on the age-dependent indicators in a greater degree and increases the bioage. This may be a cause of lower life expectancy for men compared with women.

How various drugs affect anxiety-related behavior in male and female rats prenatally exposed to methamphetamine.

Different forms of anxiety-related behavior have been reported after a single drug use of many abused substances, however, less is known about how males and females are affected differently from exposure to various drugs. Furthermore, chronic prenatal methamphetamine (MA) exposure was shown to predispose the animal to an increased sensitivity to drugs administrated in adulthood. Using the Elevated plus-maze test (EPM), the first aim of the present study was to examine how male and female rats are affected by acute drug treatment with subcutaneously (s.c.) administrated (a) MA (1mg/kg); (b) drugs with a similar mechanism of action to MA: amphetamine (AMP, 1mg/kg), cocaine (COC, 5mg/kg), 3,4-methylenedioxymethamphetamine (MDMA, 5mg/kg); and (c) drugs with different mechanisms of action: morphine (MOR, 5mg/kg), and Δ 9-tetrahydrocannabinol (THC, 2mg/kg). The second aim was to determine if prenatally MA-exposed (5mg/kg) animals show an increased sensitivity to adult drug treatment. The parameters analyzed were divided into two categories: anxiety-related behavior and anxiety-unrelated/exploratory behavior. Our results showed in female rats a decreased percentage of the time spent in the closed arms (CA) after MA, and an increased percentage of the time spent in the open arms (OA) after MA, AMP, and COC treatment, indicating an anxiolytic-like effect. In females, MDMA and THC treatment increased the percentage of the time spent in the CA. An increased percentage of the time spent in the CA was also seen after MOR treatment in females as well as in males, indicating an anxiogenic-like effect. As far as the interaction between prenatal MA exposure and adult drug treatment is concerned, there was no effect found. In conclusion, it seems that: (a) in some cases female rats are more vulnerable to acute drug treatment, in terms of either anxiogenic- or anxiolytic-like effects; (b) prenatal MA exposure does not sensitize animals to the anxiety-related effects of any of the

To study the epidemiology, characteristics, and survival of male breast cancer patients. This non-randomized retrospective study includes male patients with breast cancer confirmed by biopsy. A total of 1568 breast cancer patients were registered in the Oncology Department, Tripoli Medical Center, Tripoli, Libya between January 1990 to June 2008. Twenty-two patients were male (1.4%). The mean age of male breast cancer patients was 61 years. They tend to have advanced local disease, as 65% of them were tumor (T)3 and T4, and 93.3% have positive lymph nodes. The preferred surgical treatment was mastectomy and axillary clearance in 65%, and 85% had invasive duct carcinoma. Regarding hormone receptor status, 70% were estrogen and progesterone positive. A total of 71% received chemotherapy as anthracycline based. During follow up, the overall recurrence rate was 47%. The bone was the most common site of relapse (37.5%). Overall survival rate was 82.4% at first, 76.5% at second, and 57% at fifth year. Two patients were brothers, and one of them developed multiple myeloma during follow up. In comparison to female patients with breast cancer, male patients are older, and have more advanced and more hormone positive disease.

Mosaicism for the FMR1 gene influences adaptive skills development in fragile X-affected males

Cohen, I.L.; Sudhalter, V.; Nolin, S.L.

Fragile X syndrome is one of the most common forms of inherited mental retardation, and the first of a new class of genetic disorders associated with expanded trinucleotide repeats. Previously, we found that about 41% of affected males are mosaic for this mutation in that some of their blood cells have an active fragile X gene and others do not. It has been hypothesized that these mosaic cases should show higher levels of functioning than those who have only the inactive full mutation gene, but previous studies have provided negative or equivocal results. In the present study, the cross-sectional developmentmore » of communication, self-care, socialization, and motor skills was studied in 46 males with fragile X syndrome under age 20 years as a function of two variables: age and the presence or absence of mosaicism. The rate of adaptive skills development was 2-4 times as great in mosaic cases as in full mutation cases. There was also a trend for cases with autism to be more prevalent in the full-mutation group. These results have implications for prognosis, for the utility of gene or protein replacement therapies for this disorder, and for understanding the association between mental retardation, developmental disorders, and fragile X syndrome. 21 refs., 3 figs.« less

To explore that it is necessary to routinely detect chromosomes in infertile patients, we investigated peripheral blood lymphocyte karyotype in 16,294 male infertile patients in the north-east of China and analysed the incidence and type of chromosomal anomaly and polymorphism. G-banding karyotype analysis of peripheral blood lymphocytes was performed in 16,294 cases. Semen analysis was performed three times in all the men. PCR and FISH confirmed the presence of the SRY gene. The rate of chromosomal anomaly in the 16,294 male infertile patients was 4.15% (677/16,294). The rates of chromosomal anomaly were 0.24% in normal semen group, 12.6% in light oligoasthenospermia group, 4.7% in moderate-to-severe oligoasthenospermia group and 9.59% in azoospermia group. There are two male infertile patients with 45,X chromosome karyotype. One X male patient had confirmed the presence of the SRY gene and FISH analysis demonstrated its location on the p arm of chromosome 13. The other X male patient had not found SRY gene in its whole-genome DNA. Meanwhile, sperm motility is slightly oligo-asthenozoospermic at the age of 35-39 and nearly azoospermic at the age of 40-45. As the rates of chromosomal anomaly are 0.24% and 12.6% even in normal semen group and light oligoasthenospermia group, the rates of chromosomal polymorphism are 5.36% and 25.51% in normal semen group and light oligoasthenospermia group, respectively; it is necessary to explore peripheral blood lymphocyte karyotype in all infertile couples. We mentioned that Y, 1, 2, 9 and 12 chromosomes were quite important about male infertility. These findings demonstrate that autosomal retention of SRY can be submicroscopic and emphasise the importance of PCR and FISH in the genetic workup of the monosomic X male. At the same time, it suggested that male infertility might be related to meiotic disturbances with spermatogenetic arrest in Y-autosome translocations, which could result in infertility by reduction of sperm

Psychopathy is a personality disorder typified by lack of empathy and impulsive antisocial behavior. Psychopathic traits may partly relate to disrupted connections between brain regions. The aim of the present study was to link abnormalities in microstructural integrity of white-matter tracts to the severity of different psychopathic traits in 15 male offenders with impulse control problems and 10 without impulse control problems. Psychopathic traits were assessed using the Psychopathy Checklist-revised (PCL-R). Diffusion-weighted MRI was used to examine white-matter tracts. Fractional anisotropy (FA), an index of white-matter integrity, was calculated for each voxel. Clusters of voxels showing a significant relationship with psychopathy severity were submitted to probabilistic tractography. No significant correlations between psychopathy severity and FA were present in the whole group of impulsive and nonimpulsive offenders. In impulsive offenders, interpersonal-affective traits (PCL-R Factor 1) were negatively correlated with FA in the anterior and posterior temporal lobe and orbitofrontal area. Further analyses indicated that elevated affective traits (PCL-R Facet 2) were specifically related to reduced FA in the right temporal lobe. Our findings suggest that white-matter abnormalities in temporal and frontotemporal tracts may be linked to the interpersonal-affective deficits of psychopathy in offenders with relatively severe impulse control problems. Our study offers novel insights into the relationships between the four facets of psychopathy and disrupted structural connectivity, and may provide new leads for further characterization of different subtypes of antisocial populations.

Dopamine is an important neuromodulator in animals and its roles in mammalian sexual behavior are extensively studied. Drosophila as a useful model system is widely used in many fields of biological studies. It has been reported that dopamine reduction can affect female receptivity in Drosophila and leave male-female courtship behavior unaffected. Here, we used genetic and pharmacological approaches to decrease the dopamine level in dopaminergic cells in Drosophila, and investigated the consequence of this manipulation on male homosexual courtship behavior. We find that reduction of dopamine level can induce Drosophila male-male courtship behavior, and that this behavior is mainly due to the increased male attractiveness or decreased aversiveness towards other males, but not to their enhanced propensity to court other males. Chemical signal input probably plays a crucial role in the male-male courtship induced by the courtees with reduction of dopamine. Our finding provides insight into the relationship between the dopamine reduction and male-male courtship behavior, and hints dopamine level is important for controlling Drosophila courtship behavior.

Radiation recall dermatitis is one of the skin sequelae that may affect oncology patients. It occurs in a previously irradiated field, when subsequent chemotherapy is given. The eruption may be elicited by chemotherapy, even several months after radiotherapy. Its mechanism is poorly understood, and the histopathologic findings have received, to date, only sketchy descriptions. A 55-year-old male affected by multiple myeloma received radiation therapy both on his left coxofemoral area, and lumbar region (D11-L1). After cyclophosphamide administration, he developed 2 well defined square-shaped, infiltrated erythematoviolaceous plaques in the prior irradiated fields. Histopathologic findings revealed a diffusely fibrosclerosing process, involving deep dermis, hypodermis, as well as the underlying muscle, while sparing the epidermis and superficial-mid dermis. Histopathology was indistinguishable from deep radio-dermatitis, panniculitis, and myositis. This is the first case providing clear evidence of the causative role of cyclophosphamide in inducing a cutaneous and subcutaneous radiation recall reaction.

Schizophrenia is a prevalent neurodevelopmental disorder of an unknown etiology and a variable phenotypic expression. In the recent years, the impact of hormones on the course of schizophrenia has been investigated. This study is aimed at assessing the level of correlating serum levels of hormones in schizophrenic male patients with their cognitive functioning measured with neuropsychological tests. In the index group there were 15 medicated male schizophrenic patients. In the control group there were 15 age and education matched healthy men. All subjects underwent analysis of serum hormones level (TSH, testosterone, estradiol, FSH, LH, progesterone and prolactin) and a battery of tests (Trail Making Test A and B, Stroop Test, Verbal and Semantic Fluency Test). The mean serum levels of the following hormones were higher in the index group than in the control group: TSH (1.76 mIU/L vs 1.58 mIU/L; p=0.66), progesterone (0.85 ng/ml vs 0.69 ng/ml; p=0.22) and prolactin (558.71 uIU/ml vs 181 uIU/ml; p=0.025). The mean levels of estradiol (24.36 pg/ml vs 25.40 ng/ml; p=0.64), FSH (3.17 mIU/ml vs 5.72 mIU/ml; p=0.019), LH (3.85 mIU/ml vs 5.77 mIU/ml; p=0.056) and testosterone (2.90 ng/ml vs 5.38 ng/ml; p=0.003) were higher in the control group. In the index group there were significant negative correlations between FSH and semantic fluency (ρ=-0.678606), progesterone and: TMT B (ρ=-0.586763), Stroop 1 (ρ=-0.701880) and Stroop 2 (ρ=-0.601074) and prolactin and TMT A (ρ=-0.579607). The preliminary results of our study show that serum levels of FSH and testosterone are significantly lower, whereas the level of prolactin is markedly higher, in schizophrenic male patients than in healthy men. There is an inverse correlation between serum levels of progesterone, FSH and prolactin and the results of certain cognitive functioning tests in schizophrenic men.

Recently, a new syndrome of paraganglioma, somatostatinoma, and polycythemia has been discovered (known as Pacak-Zhuang syndrome). This new syndrome, with somatic HIF2A gain-of-function mutations, has never been reported in male patients. We describe a male patient with Pacak-Zhuang syndrome who carries a newly discovered HIF2A mutation. Congenital polycythemias have diverse etiologies, including germline mutations in the oxygen-sensing pathway. These include von Hippel-Lindau (Chuvash polycythemia), prolyl hydroxylase domain-containing protein-2, and hypoxia-inducible factor-2α (HIF-2α). Somatic gain-of-function mutations in the gene encoding HIF-2α were reported in patients with paraganglioma and polycythemia and have been found exclusively in female patients. Through sequencing of the HIF2A using DNA from paraganglioma in 15-year-old male patient, we identified a novel mutation of HIF2A: a heterozygous C to A substitution at base 1589 in exon 12 of HIF2A. The mutation was not found in germline DNA from leukocytes. The C1589A mutations resulted in substitution of alanine 530 in the HIF-2α protein with glutamic acid. This mutation is undoubtedly associated with increased HIF-2α activity and increased protein half-life, because it affects the vicinity of the prolyl hydroxylase target residue, proline 531. To our knowledge, this is the first report describing Pacak-Zhuang syndrome with somatic gain-of-function mutation in HIF2A in a male patient. Congenital polycythemia of unknown origin should raise suspicion for the novel disorder Pacak-Zhuang syndrome, even in male patients. Copyright © 2014 by the American Academy of Pediatrics.

Previous studies have shown that major depressive patients may differ in several features according to gender, but the existence of a specific male depressive syndrome remains controversial. As part of the EPIDEP National Multisite French Study of 493 consecutive DSM-IV major depressive patients evaluated in at least two semi-structured interviews 1 month apart, 125 (27.7%) were of male gender, whereas 317 (72.3%) were female, after exclusion of bipolar I patients. Compared to women, men were more often married, had more associated mixed features, with more bipolar disorder NOS, more hyperthymic temperaments, and less depressive temperaments. Women had an earlier age at onset of depression, more depressive episodes and suicide attempts. A higher family loading was shown in men for bipolar disorder, alcohol use disorder, impulse control disorders and suicide, whereas their family loading for major depressive disorder was lower. Men displayed more comorbidities with alcohol use, impulse control, and cardiovascular disorders, with lower comorbidities with eating, anxiety and endocrine/metabolic disorders. The following independent variables were associated with male gender: hyperthymic temperament (+), alcohol use disorder (+), impulse control disorders (+), and depressive temperament (-). The retrospective design and the lack of specific tools to assess the male depressive syndrome. Study findings may lend support to the male depression syndrome concept and draw attention to the role of hyperthymic temperament, soft bipolarity as well as comorbidities as determinants of this syndrome. The latter could help recognize an entity which is probably underdiagnosed, but conveys a high risk of suicide and cardiovascular morbidity. Copyright © 2014 Elsevier B.V. All rights reserved.

The current study aims to explore the interrelationships between affect recognition and basic neurocognitive functions for patients with BD across different mood states, using the Diagnostic Analysis of Non-Verbal Accuracy-2, Taiwanese version (DANVA-2-TW) as the index measure for affect recognition. To our knowledge, this is the first study examining affect recognition deficits of BPD across mood states in the Han Chinese population. Twenty-nine manic patients, 16 remitted patients with BD, and 40 control subjects are included in the study. Distinct association patterns between affect recognition and neurocognitive functions are demonstrated for patients with BD and control subjects, implicating alternations in emotion associated neurocognitive processing. Compared to control subjects, manic patients but not remitted subjects perform significantly worse in the recognition of negative emotions as a whole and specifically anger, after adjusting for differences in general intellectual ability and basic neurocognitive functions. Affect recognition deficit may be a relatively independent impairment in BD rather than consequences arising from deficits in other basic neurocognition. The impairments of manic patients in the recognition of negative emotions, specifically anger, may further our understanding of core clinical psychopathology of BD and have implications in treating bipolar patients across distinct mood phases. © 2013 Elsevier B.V.

Chronic obstructive pulmonary disease (COPD) is a disease with great impact on the ability to carry out physical activity. To identify the main factors that affect physical activity in the daily life of patients with COPD. Physical activity in daily routine has been evaluated according to the London Chest Activity of Daily Living scale (LCADL) and the pedometer counting the number of steps per day, for a period of three days. Fifty-five male patients with a diagnosis of moderate to very severe COPD were included (aged 67±9.6 years; FEV1 50.8±14.7% predicted). Patients walked on average 4972 steps per day. Very severe COPD patients (n=12) walked much less than severe (n=21) and moderate (n=22) patients (respectively 3079.8 versus 4853.5 and 6118.1 steps per day, p<0.001). The number of steps per day had a negative correlation with age, dyspnea (mMRC), depression, BODE index and pulmonary hyperinflation; and a positive correlation with the distance covered in the six-minute walk test (6MWT), forced expiratory volume in the first second (FEV1), carbon monoxide diffusion capacity (DLCO), arterial oxygen saturation (SpO2) and body mass index (BMI). The main factors that correlated with limited physical activity in daily life routine of this group of COPD patients were dyspnea and 6 min walking distance. These patients form a sedentary group, with a low rate of daily physical activity, which is more evident in patients with GOLD spirometry stage IV. Although pedometer is simpler and less accurate than other devices, it can be used to detect significant restraints daily life physical activity of COPD patients.

Burns are physically, psychologically and economically challenging injuries, and the factors leading to them are many and under-studied. The aim of the current study was to assess level of anxiety, depression and self-esteem in burn patients, and look at various burn-related variables that affect them. This cross-sectional study included 100 patients with burn injuries admitted to a tertiary care private hospital in an urban metropolis in India. The patients were assessed for anxiety, depression and self-esteem using the Hamilton anxiety rating scale, Hamilton depression rating scale and Rosenberg self-esteem scale respectively. Assessment was carried out within 2-8 weeks of injury following medical stabilization. The data was tabulated and statistically analyzed. The study sample was predominantly male (54%), married (69%), with a mean age of 34.1 ± 10.8 years. Accidental burns (94%) were the most common modality of injury. The majority (46%) suffered burns involving 20-59% total body surface area (TBSA), and facial burns were present (57%). No significant association was found between TBSA and anxiety, depression or self-esteem, and the same was true for facial burns. Deep burns, however, were significantly associated with anxiety (p=0.03) and depression (p=0.0002). High rates of anxiety and depression are associated with burn injuries and related to burn depth. Adjustment and recovery in these patients depends on various other factors like the patient's psychological status, nature/extent of the injury and ensuing medical care. Further research is warranted to reveal the magnitude and predictors of psychological problems in burn patients.

Cognitive Impacts of Estrogen Treatment in Androgen-Deprived Males: What Needs to be Resolved.

PubMed

Wibowo, Erik

2017-01-01

Many prostate cancer (PCa) patients are on androgen deprivation therapy (ADT) as part of their cancer treatments but ADT may lead to cognitive impairments. ADT depletes men of both androgen and estrogen. Whether estradiol supplementation can improve cognitive impairments in patients on ADT is understudied. To summarize data on the effects of estradiol treatment on cognitive function of androgen-deprived genetic male populations (PCa patients and male-to-female transsexuals) and castrated male animals. Publications were identified by a literature search on PubMed and Google Scholar. While some studies showed that estradiol improves cognitive function (most notably, spatial ability) for castrated rats, what remains uninvestigated are: 1) whether estradiol can improve cognition after long-term androgen deprivation, 2) how estradiol affects memory retention, and 3) how early vs. delayed estradiol treatment after castration influences cognition. For androgendeprived genetic males, estradiol treatment may improve some cognitive functions (e.g., verbal and visual memory), but the findings are not consistent due to large variability in the study design between studies. Future studies are required to determine the best estradiol treatment protocol to maximize cognitive benefits for androgen-deprived genetic males. Tests that assess comparable cognitive domains in human and rodents are needed. What particularly under-investigated is how the effects of estradiol on cognitive ability intersect with other parameters; sleep, depression and physical fatigue. Such studies have clinical implications to improve the quality of life for both PCa patients on ADT as well as for male-to-female transsexuals.

Mutation of Drosophila dopamine receptor DopR leads to male-male courtship behavior.

PubMed

Chen, Bin; Liu, He; Ren, Jing; Guo, Aike

2012-07-06

In Drosophila, dopamine plays important roles in many biological processes as a neuromodulator. Previous studies showed that dopamine level could affect fly courtship behaviors. Disturbed dopamine level leads to abnormal courtship behavior in two different ways. Dopamine up-regulation induces male-male courtship behavior, while down-regulation of dopamine level results in increased sexual attractiveness of males towards other male flies. Until now, the identity of the dopamine receptor involved in this abnormal male-male courtship behavior remains unknown. Here we used genetic approaches to investigate the role of dopamine receptors in fly courtship behavior. We found that a dopamine D1-like receptor, DopR, was involved in fly courtship behavior. DopR mutant male flies display male-male courtship behavior. This behavior is mainly due to the male's increased propensity to court other males. Expression of functional DopR successfully rescued this mutant phenotype. Knock-down of D2-like receptor D2R and another D1-like receptor, DAMB, did not induce male-male courtship behavior, indicating the receptor-type specificity of this phenomenon. Our findings provide insight into a possible link between dopamine level disturbance and the induced male-male courtship behavior. Copyright © 2012 Elsevier Inc. All rights reserved.

Background A high frequency of hypogonadism has been reported in male patients with advanced cancer. Objectives To evaluate the association among low testosterone, symptom burden and survival in cancer patients. Methods 119/131 (91%) consecutive male cancer patients had an endocrine evaluation of total/free/bioavailable testosterone (TT, FT, BT, respectively), high-sensitivity C-reactive protein (CRP), vitamin B12, thyroid stimulating hormone, 25-hydroxy vitamin D and cortisol levels when presenting with symptoms of fatigue and/or anorexia-cachexia. Symptoms were evaluated by the Edmonton Symptom Assessment Scale. We examined the correlation with Spearman test and survival with log rank test and Cox-regression analysis. Results The median age was 64; majority were white 85 (71%). Median TT was 209ng/dL (normal ≥200 ng/dL), FT was 4.4 ng/dL (normal ≥9 ng/dL), and BT was 22.0 ng/dL (normal ≥61ng/dL). Low TT, FT, and BT values were all associated with worse fatigue (p≤0.04), poor performance status (p≤0.05), weight loss (p≤0.01), and opioid use (p≤0.005). Low TT and FT were associated with increased anxiety (p≤0.04), decreased feeling of well-being (p≤0.04), and increased dyspnea (p≤0.05); while BT was only associated with anorexia (p=0.05). Decreased TT, FT, and BT values were all significantly associated with elevated CRP, low albumin and hemoglobin. In multivariate analysis, decreased survival was associated with low TT (HR 1.66; p=0.034), declining ECOG performance status (HR 1.55; p=0.004), high CRP (HR 3.28; p<0.001), and decreased albumin (HR 2.52; p<0.001). Conclusion In male cancer patients, low testosterone was associated with systemic inflammation, weight loss, increased symptom burden, and decreased survival. PMID:24577665

Medical male circumcision: How does price affect the risk-profile of take-up?

The benefit of male circumcision is greatest among men who are most at risk of HIV infection. Encouraging this population of men to get circumcised maximizes the benefit that can be achieved through the scale-up of circumcision programs. This paper examines how the price of circumcision affects the risk profile of men who receive a voluntary medical circumcision. In 2010, 1649 uncircumcised adult men in urban Malawi were interviewed and provided a voucher for a subsidized voluntary medical male circumcision, at randomly assigned prices. Clinical data were collected indicating whether the men in the study received a circumcision. Men who took-up circumcision with a zero-priced voucher were 25 percentage points less likely than those who took-up with a positive-price voucher, to be from a tribe that traditionally circumcises (p=0.101). Zero-priced vouchers also brought in men with more sexual partners in the past year (p=0.075) and past month (p=0.003). None of the men who were most at risk of HIV at baseline (those with multiple partners and who did not use a condom the last time they had sex) received a circumcision if they were offered a positive-priced voucher. Lowering the price to zero increased circumcision take-up to 25% for men of this risk group. The effect of price on take-up was largest among those at highest risk (p=0.096). Reducing the price of circumcision surgery to zero can increase take-up among those who are most at risk of HIV infection. Copyright © 2016 Elsevier Inc. All rights reserved.

The purpose of this cross-sectional study was to investigate the toe pinch force (TPF) of type 2 diabetic patients with diabetic nephropathy by disease stage, and to clarify the factors affecting the TPF. Seventy-four men with diabetic nephropathy (age: 62.7 ± 8.9 years, duration of diabetes: 14.2 ± 8.6 years) were enrolled. According to the staging of diabetic nephropathy, TPF and knee extension force (KEF) were compared among three groups: normoalbuminuria, microalbuminuria, and overt nephropathy. In addition, we investigated factors influencing TPF and KEF by performing multiple regression analysis. Normoalbuminuria group, microalbuminuria group, and overt nephropathy group included 26, 25, and 23 patients, respectively. The TPF of the overt nephropathy group (3.15 ± 0.75 kg) was significantly lower than that of the normoalbuminuria (4.2 ± 0.7 kg, p < 0.001) and microalbuminuria groups (3.65 ± 0.81 kg, p = 0.022). The KEF of the overt nephropathy group (37.1 ± 8.3 kgf) was significantly lower than that of the normoalbuminuria group (44.8 ± 8.3 kgf, p = 0.010). Multiple regression analysis revealed that diabetic polyneuropathy (DPN) and diabetic nephropathy were determinant factors of the TPF; and age, body mass index, and diabetic nephropathy were determinant factors of the KEF. We found in male patients with diabetic nephropathy, the TPF and KEF decreased with progression of diabetic nephropathy. Furthermore, our findings suggest diabetic nephropathy and DPN are critically involved in the reduction of TPF and KEF.

Xq28 duplications encompassing MECP2 have been described in male patients with a severe neurodevelopmental disorder associated with hypotonia and spasticity, severe learning disability, stereotyped movements, and recurrent pulmonary infections. We report on standardized brain magnetic resonance imaging (MRI) data of 30 affected patients carrying an Xq28 duplication involving MECP2 of various sizes (228 kb to 11.7 Mb). The aim of this study was to seek recurrent malformations and attempt to determine whether variations in imaging features could be explained by differences in the size of the duplications. We showed that 93% of patients had brain MRI abnormalities such as corpus callosum abnormalities (n = 20), reduced volume of the white matter (WM) (n = 12), ventricular dilatation (n = 9), abnormal increased hyperintensities on T2-weighted images involving posterior periventricular WM (n = 6), and vermis hypoplasia (n = 5). The occipitofrontal circumference varied considerably between >+2SD in five patients and <-2SD in four patients. Among the nine patients with dilatation of the lateral ventricles, six had a duplication involving L1CAM. The only patient harboring bilateral posterior subependymal nodular heterotopia also carried an FLNA gene duplication. We could not demonstrate a correlation between periventricular WM hyperintensities/delayed myelination and duplication of the IKBKG gene. We thus conclude that patients with an Xq28 duplication involving MECP2 share some similar but non-specific brain abnormalities. These imaging features, therefore, could not constitute a diagnostic clue. The genotype-phenotype correlation failed to demonstrate a relationship between the presence of nodular heterotopia, ventricular dilatation, WM abnormalities, and the presence of FLNA, L1CAM, or IKBKG, respectively, in the duplicated segment. © 2015 Wiley Periodicals, Inc.

Improved long-term survival of colorectal cancer patients (CRC) treated with surgery and/or chemotherapy ± radiotherapy (RT) has led to increased awareness of long-term side effects, including effecting sexual life, which can ultimately affect the quality of life in these patients. Because the absolute risk factors of erectile dysfunction (ED) have not been defined in CRC patients, the aim of this research was to identify the severity and the absolute risk factors of ED in male CRC survivors. The medical records of 61 male survivors of CRC treated with surgery and/or chemotherapy ± RT were retrieved from the medical oncology outpatient clinics during routine follow-up visits in 2011-2012. Patients older than 55 years and those with ED history before diagnosis were excluded. International Index of Erectile Function (IIEF) questionnaire was filled in by the patients. The patient mean age was 47.6±6.7 years (range 18-55) at the time of filling in the questionnaire. According to the International Index of Erectile Function (IIEF) score, 83.6% of the patients had some degree of ED. The risk factors of erectile dysfunction were advancing age (p=0.01), tumor location (p=0.01), type of surgery (p=0.02), presence of stoma (p=0.03)) and RT (p=0.005). Chemotherapy didn't impact ED (p=0.46). Also, there was no significant correlation between smoking status, hypertension, diabetes mellitus, cardiovascular disease, stage of the tumor and ED. Also hormonal disturbances such as serum FSH, LH and testesterone levels did not affect the presence of ED. Overall, 83.6% of the male CRC survivors had some degree of ED according to the IIEF. The risk factors of ED were advancing age, tumor location, type of operation, presence of stoma and RT. Clinicians should be aware of these risk factors to offer their patients adequate treatment options and also come up with new treatment strategies necessary to reduce further ED in CRC survivors.

Osteopontin (OPN) is an extracellular matrix protein with multifunctions, expressed in various tissues and body fluids, involved in various physiological and pathological processes. It is also detected in the reproductive tract of both males and females, and participates in the implantation, development and differentiation of embryos. Recent studies have indicated that OPN is closely related with male fertility and may affect sperm quality and fertilization. An insight into the functions of OPN may help to explain the mechanisms of male infertility and improve the success rate of assisted reproductive technology.

The objective of this study was to evaluate the implant stability and peri-implant tissue response in heavy smokers receiving dental implants due to partially edentulous posterior mandibles. Forty-five ITI Straumann dental implants were placed into the partially edentulous posterior mandibles of 16 heavy smokers and 16 nonsmokers. One implant in each patient was evaluated for implant stability after surgery and before loading, and for the modified plaque index (mPLI), modified sulcus bleeding index (mSBI), probing depth (PD), and marginal bone loss (MBL) after loading. Meanwhile, the osteogenic capability of jaw marrow samples collected from patients was evaluated via an in vitro mineralization test. For both groups, the implant stability quotient (ISQ) initially decreased from the initial ISQ achieved immediately after surgery and then increased starting from 2 weeks postsurgery. However, at 3, 4, 6, and 8 weeks postsurgery, the ISQ differed significantly between nonsmokers and heavy smokers. All implants achieved osseointegration without complications at least by the end of the 12th week postsurgery. At 6 or 12 months postloading, the MBL and PD were significantly higher in heavy smokers than in nonsmokers, whereas the mSBI and mPLI did not differ significantly between the 2 groups. The 1-year cumulative success rate of implants was 100% for both groups. Within the limitations of the present clinical study (such as small sample size and short study duration), which applied the loading at 3 months postoperation, heavy smoking did not affect the cumulative survival rate of dental implants placed at the posterior mandible in male patients, but heavy smoking did negatively affect bone healing around dental implants by decreasing the healing speed. These results implied that it might be of importance to select the right time point to apply the implant loading for heavy smokers. In addition, heavy smoking promoted the loss of marginal bone and the further development

Quality of life (QOL) has become an important outcome measure in the care of dementia patients. However, there have been few studies focusing on the difference in QOL between different dementias. Two-hundred seventy-nine consecutive outpatients with Alzheimer's disease (AD), dementia with Lewy bodies (DLB) or frontotemporal dementia (FTD) were recruited. The QOL was evaluated objectively using the QOL Questionnaire for Dementia (QOL-D).The QOL-D comprises six domains: positive affect, negative affect and actions, communication, restlessness, attachment to others, and spontaneity. General cognition, daily activities, and behavioral and psychological symptoms of dementia were also evaluated. The scores of positive affect of QOL-D of AD patients were significantly higher than those of patients with DLB or FTD (AD 3.1 ± 0.8, DLB 2.6 ± 0.9, FTD 2.6 ± 0.7). The scores of negative affect and action of QOL-D of FTD patients were significantly higher than those of patients with AD or DLB (FTD 2.0 ± 0.8, AD 1.4 ± 0.5, DLB 1.5 ± 0.6). The apathy scores of FTD and DLB patients were significantly higher than those of patients with AD. The disinhibition scores of FTD patients were significantly higher than those of patients with AD or DLB. The apathy of FTD and DLB patients and depression of DLB patients might affect the lower positive affect of FTD and DLB patients compared to AD patients. The disinhibition of FTD patients might affect the abundance of negative affect & actions in FTD patients compared to AD and DLB patients.

The purpose of the study was to identify the style of parental bonding and the personality characteristics that might increase the risk of hyperventilation and adjustment disorder. A total of 917 males were recruited, 156 with adjustment disorder and hyperventilation syndrome (AD + HY), 273 with adjustment disorder without hyperventilation syndrome (AD-HY), and 488 healthy controls. All participants completed the Parental Bonding Instrument, Eysenck Personality Questionnaire, and Chinese Health Questionnaire. Analysis using structural equation models identified a pathway relationship in which parental bonding affected personality characteristics, personality characteristics affected mental health condition, and mental health condition affected the development of hyperventilation or adjustment disorder. Males with AD-HY perceived less paternal care, and those with AD + HY perceived more maternal protection than those with adjustment disorder and those in the control group. Participants with AD-HY were more neurotic and less extroverted than those with AD + HY. Both groups showed poorer mental health than the controls. Although some patients with hyperventilation syndrome demonstrated symptoms of adjustment disorder, there were different predisposing factors between the two groups in terms of parental bonding and personality characteristics. This finding is important for the early intervention and prevention of hyperventilation and adjustment disorder.

The aim of this study is to investigate the amount and the distribution of biofilm in patients wearing fixed appliances and its relation with age, gender, frequency of tooth brushing, and patient motivation. The sample comprised 52 patients (15.5 ± 3.6 years old, 30 females and 22 males) wearing fixed orthodontic appliances. Dental biofilm was assessed using a modified plaque index (PI). A questionnaire was used to collect patient's information, including gender, age, treatment motivation, and frequency of tooth brushing. Gingival (PI score = 0.9 ± 0.7), mesial (0.8 ± 0.6), and distal (0.8 ± 0.5) areas accumulated more biofilm than occlusal areas (0.3 ± 0.3) (P < 0.038). The maxillary lateral incisors (1.1 ± 0.8) and maxillary canines (1.0 ± 0.8) had more biofilm than other teeth (P < 0.05). The maxillary arch (0.8 ± 0.7) had significantly more biofilm than mandibular arch (0.6 ± 0.6) (P = 0.042). No significant difference was found between the right side (0.7 ± 0.7) and left side (0.7 ± 0.6) (P = 0.627). Less biofilm was found in females (0.6 ± 0.5), adults (0.3 ± 0.3), and "self-motivated" patients (0.3 ± 0.3), compared with males (0.9 ± 0.5), children (0.8 ± 0.6), and "family-motivated" patients (1.1 ± 0.5) (P < 0.001). The amount of biofilm was associated with self-report of the frequency of daily tooth brushing (P < 0.001). Patients wearing fixed orthodontic appliances have the highest biofilm accumulation on the maxillary lateral incisors and maxillary canines, particularly in the gingival area and areas behind arch wires. Less biofilm was observed in female and adult patients and in those who were self-motivated and brushed their teeth more often.

After a registered drug is available on the market and used in everyday circumstances, hitherto unknown adverse drug reactions (ADRs) may occur. Furthermore, the patient can experience a previously unknown course of a known ADR. Voluntary reports by patients play an important role in gaining knowledge about ADRs in daily practice. The Netherlands Pharmacovigilance Centre Lareb received a report from a 55-year-old female-to-male transgender patient who experiences secondary polycythemia while using lifelong testosterone therapy. The onset age of the symptoms was 38 years. The symptoms appeared gradually and after approximately 1 year it was clear that the patient's hemoglobin and hematocrit had started to increase. A Naranjo assessment score of 6 was obtained, indicating a probable relationship between the patient's polycythemia and use of the suspect drug. Polycythemia is a known ADR in testosterone treatment, but little attention has been paid to the possible severity and complications of these symptoms as well as the impact on the patient's well-being.

While it is anticipated that decubitus ulcers are detrimental to outcomes after vascular operations, the contemporary influence of perioperative decubitus ulcers in vascular surgery remains unknown. Using the National Impatient Survey, all adult patients who underwent vascular operation were selected. Patients were stratified by the presence or absence (non-decubitus ulcers) of decubitus ulcer. Case-mix adjusted hierarchical mixed-models examined in-hospital mortality, the occurrence of any complication, and discharge disposition. A total of 538,808 cases were analyzed. Decubitus ulcers were most prevalent among Caucasian male Medicare beneficiaries (P < .001). Decubitus ulcer patients also underwent more nonelective vascular operations (P < .001). Wound, infectious, and procedural complications were more common in patients with decubitus ulcers (P < .001). Failure to rescue, defined as mortality after any complication, was more than doubled in decubitus ulcers (non-decubitus ulcers: 1.5%, decubitus ulcers: 3.2%, P < .001). Similarly, unadjusted mortality was also doubled in patients undergoing vascular operation with decubitus ulcers (non-decubitus ulcers: 3%, decubitus ulcers: 6%, P < .001). After risk adjustment among all patients, neither the presence of a decubitus ulcer nor specific ulcer staging increased the adjusted odds of death. Having a decubitus ulcer increased the adjusted odds of discharge to an intermediate care facility (odds ratio 2.9, P < .001). These patients also had 1.6 times the total charges compared to their non-decubitus ulcer cohort (non-decubitus ulcers: $49,460 ± $281 vs decubitus ulcers: $81,149 ± $5,855, P < .001). Contrary to common perception, perioperative decubitus ulcer does not adversely affect mortality after vascular operation in patients proceeding to operative intervention. Patients with decubitus ulcers are, however, at higher risk for complications and incur sizeable additional charges. Copyright �

Male and female voices activate distinct regions in the male brain.

In schizophrenia, auditory verbal hallucinations (AVHs) are likely to be perceived as gender-specific. Given that functional neuro-imaging correlates of AVHs involve multiple brain regions principally including auditory cortex, it is likely that those brain regions responsible for attribution of gender to speech are invoked during AVHs. We used functional magnetic resonance imaging (fMRI) and a paradigm utilising 'gender-apparent' (unaltered) and 'gender-ambiguous' (pitch-scaled) male and female voice stimuli to test the hypothesis that male and female voices activate distinct brain areas during gender attribution. The perception of female voices, when compared with male voices, affected greater activation of the right anterior superior temporal gyrus, near the superior temporal sulcus. Similarly, male voice perception activated the mesio-parietal precuneus area. These different gender associations could not be explained by either simple pitch perception or behavioural response because the activations that we observed were conjointly activated by both 'gender-apparent' and 'gender-ambiguous' voices. The results of this study demonstrate that, in the male brain, the perception of male and female voices activates distinct brain regions.

Sex-specific pheromones are known to play an important role in butterfly courtship, and may influence both individual reproductive success and reproductive isolation between species. Extensive ecological, behavioural and genetic studies of Heliconius butterflies have made a substantial contribution to our understanding of speciation. Male pheromones, although long suspected to play an important role, have received relatively little attention in this genus. Here, we combine morphological, chemical and behavioural analyses of male pheromones in the Neotropical butterfly Heliconius melpomene. First, we identify putative androconia that are specialized brush-like scales that lie within the shiny grey region of the male hindwing. We then describe putative male sex pheromone compounds, which are largely confined to the androconial region of the hindwing of mature males, but are absent in immature males and females. Finally, behavioural choice experiments reveal that females of H. melpomene, H. erato and H. timareta strongly discriminate against conspecific males which have their androconial region experimentally blocked. As well as demonstrating the importance of chemical signalling for female mate choice in Heliconius butterflies, the results describe structures involved in release of the pheromone and a list of potential male sex pheromone compounds.

Schmid Mast, Marianne; Hall, Judith A; Roter, Debra L

2007-09-01

The present study aimed to investigate the effect of physician sex and physician communication style on patient satisfaction. In real medical visits, physician sex and physician communication style are confounded variables. By using the virtual medical visit paradigm, we were able to disentangle the two variables and study their separate and/or joint effects on patient satisfaction. In an experimental design, analogue patients (167 students) interacted with a computer-generated virtual physician on a computer screen. The patients' satisfaction during the visit was assessed. Depending on the sex composition of the dyad, physician communication style affected analogue patients' satisfaction differently. For instance, in male-male dyads, physician communication style did not affect the patients' satisfaction, whereas in female-female dyads, analogue patients were more satisfied when the physician adopted a caring as opposed to a non-caring communication style. Sex of the physician and sex of the patient moderate how different physician communication styles affect patient satisfaction. In particular, a female-sex role congruent communication style leads to higher patient satisfaction when women see a female physician. Physician communication training cannot be one size fits all. Rather female and male physicians should obtain different training and they need to be made aware of the fact that female and male patients harbor different expectations toward them.

The objective of this study was to characterize hypopituitarism in adult males with prolactinomas. We retrospectively analyzed the records of 102 consecutive patients, classified under three categories based on adenoma size at diagnosis: 1.0-2.0cm (group A), 2.1-4.0cm (group B), and >4.0cm (group C). Further, 76 patients had successful outcomes at follow-up. We compared different forms of pituitary hormone dysfunction (growth hormone deficiency, hypogonadism, hypothyroidism, and hypocortisolism) based on the maximal adenoma diameter. Serum prolactin levels were significantly correlated with the maximal adenoma diameter (r=0.867; P=0.000). Of the patients, 89.2% presented with pituitary failure, which included 74.5% with growth hormone deficiency, 71.6% with hypogonadism, 28.4% with hypothyroidism, and 12.7% with hypocortisolism. The three groups did not differ significantly (P>0.05) in the incidence of hypopituitarism, including the extent of pituitary axis deficiency, at presentation and following treatment. However, there was a statistically significant difference in the degree of hypogonadism in cases of acquired pituitary insufficiency at diagnosis (P=0.000). In adult males with prolactin-secreting adenomas, the most common form of pituitary hormone dysfunction was growth hormone deficiency and hypogonadism, whereas hypocortisolism was less common. The maximal adenoma diameter and prolactin secretion did not determine hormone insufficiency in adult males with prolactinomas, but these factors did affect the degree of both hypogonadism and hypothyroidism. Smaller tumors were found to recur more frequently than large tumors, and recovery was more common in cases of growth hormone deficiency and hypogonadism. Copyright © 2016 Elsevier B.V.

Both schizophrenia and bipolar disorder (BD) have consistently been associated with deficits in facial affect recognition (FAR). These impairments have been related to various aspects of social competence and functioning and are relatively stable over time. However, individuals in remission may outperform patients experiencing an acute phase of the disorders. The present study directly contrasted FAR in symptomatically remitted patients with schizophrenia or BD and healthy volunteers and investigated its relationship with patients' outcomes. Compared to healthy control subjects, schizophrenia patients were impaired in the recognition of angry, disgusted, sad and happy facial expressions, while BD patients showed deficits only in the recognition of disgusted and happy facial expressions. When directly comparing the two patient groups individuals suffering from BD outperformed those with schizophrenia in the recognition of expressions depicting anger. There was no significant association between affect recognition abilities and symptomatic or psychosocial outcomes in schizophrenia patients. Among BD patients, relatively higher depression scores were associated with impairments in both the identification of happy faces and psychosocial functioning. Overall, our findings indicate that during periods of symptomatic remission the recognition of facial affect may be less impaired in patients with BD than in those suffering from schizophrenia. However, in the psychosocial context BD patients seem to be more sensitive to residual symptomatology. Copyright © 2013 Elsevier B.V. All rights reserved.

Abnormal brain processing of affective and sensory pain descriptors in chronic pain patients.

Previous research has suggested that chronic pain patients might be particularly vulnerable to the effects of negative mood during information processing. However, there is little evidence for abnormal brain processing of affective and sensory pain-related information in chronic pain. Behavioral and brain responses, to pain descriptors and pleasant words, were examined in chronic pain patients and healthy controls during a self-endorsement task. Eighteen patients with fibromyalgia (FM), 18 patients with chronic musculoskeletal pain due to identifiable physical injury (MSK), and 16 healthy controls were asked to decide whether word targets described their current or past experience of pain. The number of self-endorsed words, elapsed time to endorse the words, and event-related potentials (ERPs) elicited by words, were recorded. Data revealed that chronic pain patients used more affective and sensory pain descriptors, and were slower in responding to self-endorsed pain descriptors than to pleasant words. In addition, it was found that affective pain descriptors elicited significantly more enhanced positive ERP amplitudes than pleasant words in MSK pain patients; whereas sensory pain descriptors elicited greater positive ERP amplitudes than affective pain words in healthy controls. These data support the notion of abnormal information processing in chronic pain patients, which might be characterized by a lack of dissociation between sensory and affective components of pain-related information, and by an exaggerated rumination over word meaning during the encoding of self-referent information about pain.

Alexithymia and affective verbal behaviour of three groups of patients.

PubMed

Ahrens, S

1985-01-01

The study described in this article was designed to investigate patients' response to affective stimuli on two levels of measurement: one was designed to yield information about cognitive attribution processes whereas the second level was aimed at uncovering deeper, more unconscious responses to the given stimuli. These were displayed as part of an experimental setting, in which three groups were compared: psychosomatic (duodenal ulcer), somatic and psychoneurotic patients. Systematic variation was introduced by showing either of two versions of a short film which differed in the degree of friendliness displayed by the main character. The results show differential effects on the two levels of measurement: in the case of the first level, an interpretation within the framework of current conceptualizations of alexithymia would have been possible, but results for the second level of measurement (utilizing Gottschalk-Gleser content analysis of speech) indicate that psychosomatic patients show the same kind of sensitive response to affective stimuli as patients from the other two groups.

We evaluated adequate setup margins for the radiotherapy (RT) of pelvic tumors based on overall position errors of bony landmarks. We also estimated the difference in setup accuracy between the male and female patients. Finally, we compared the patient rotation for 2 immobilization devices. The study cohort included consecutive 64 male and 64 female patients. Altogether, 1794 orthogonal setup images were analyzed. Observer-related deviation in image matching and the effect of patient rotation were explicitly determined. Overall systematic and random errors were calculated in 3 orthogonal directions. Anisotropic setup margins were evaluated based on residual errors after weekly image guidance.more » The van Herk formula was used to calculate the margins. Overall, 100 patients were immobilized with a house-made device. The patient rotation was compared against 28 patients immobilized with CIVCO's Kneefix and Feetfix. We found that the usually applied isotropic setup margin of 8 mm covered all the uncertainties related to patient setup for most RT treatments of the pelvis. However, margins of even 10.3 mm were needed for the female patients with very large pelvic target volumes centered either in the symphysis or in the sacrum containing both of these structures. This was because the effect of rotation (p ≤ 0.02) and the observer variation in image matching (p ≤ 0.04) were significantly larger for the female patients than for the male patients. Even with daily image guidance, the required margins remained larger for the women. Patient rotations were largest about the lateral axes. The difference between the required margins was only 1 mm for the 2 immobilization devices. The largest component of overall systematic position error came from patient rotation. This emphasizes the need for rotation correction. Overall, larger position errors and setup margins were observed for the female patients with pelvic cancer than for the male patients.« less

Inbreeding affects sexual signalling in males but not females of Tenebrio molitor.

In many species of animals, individuals advertise their quality with sexual signals to obtain mates. Chemical signals such as volatile pheromones are species specific, and their primary purpose is to influence mate choice by carrying information about the phenotypic and genetic quality of the sender. The deleterious effects of consanguineous mating on individual quality are generally known, whereas the effect of inbreeding on sexual signalling is poorly understood. Here, we tested whether inbreeding reduces the attractiveness of sexual signalling in the mealworm beetle, Tenebrio molitor, by testing the preferences for odours of inbred and outbred (control) individuals of the opposite sex. Females were more attracted to the odours produced by outbred males than the odours produced by inbred males, suggesting that inbreeding reduces the attractiveness of male sexual signalling. However, we did not find any difference between the attractiveness of inbred and outbred female odours, which may indicate that the quality of females is either irrelevant for T. molitor males or quality is not revealed through female odours.

Background Patients with schizophrenia often experience problems regulating their emotions. Non-affected relatives show similar difficulties, although to a lesser extent, and the neural basis of such difficulties remains to be elucidated. In the current paper we investigated whether schizophrenia patients, non-affected siblings and healthy controls (HC) exhibit differences in brain activation during emotion regulation. Methods All subjects (n = 20 per group) performed an emotion regulation task while they were in an fMRI scanner. The task contained two experimental conditions for the down-regulation of emotions (reappraise and suppress), in which IAPS pictures were used to generate a negative affect. We also assessed whether the groups differed in emotion regulation strategies used in daily life by means of the emotion regulation questionnaire (ERQ). Results Though the overall negative affect was higher for patients as well as for siblings compared to HC for all conditions, all groups reported decreased negative affect after both regulation conditions. Nonetheless, neuroimaging results showed hypoactivation relative to HC in VLPFC, insula, middle temporal gyrus, caudate and thalamus for patients when reappraising negative pictures. In siblings, the same pattern was evident as in patients, but only in cortical areas. Conclusions Given that all groups performed similarly on the emotion regulation task, but differed in overall negative affect ratings and brain activation, our findings suggest reduced levels of emotion regulation processing in neural circuits in patients with schizophrenia. Notably, this also holds for siblings, albeit to a lesser extent, indicating that it may be part and parcel of a vulnerability for psychosis. PMID:24941136

To assess the impact of listening to preferred music on relieving male patients' pain and anxiety during flexible cystoscopy. A total of 124 male patients were admitted to our hospital for flexile cystoscopy by a single urologist between January 2013 and September 2013 and randomized to two equal groups. Group 2 included 62 patients who could select and listen to their preferred music during flexible cystoscopy. Group 1 included 62 patients who were unable to listen to the music. All patients were administered the same amount of lidocaine (10 mL) for 3 minutes for local anesthesia before flexible cystoscopy. A visual analog scale (VAS) ranging from 0 to 10 was used to assess patients' pain feeling after the cystoscopy procedure. Anxiety levels were calculated according to the State Instrument of State-Trait Anxiety Inventory (STAI-S), and the pulse rate were recorded 5 minutes before and immediately after the procedure. The duration of the procedure of each group were also analyzed. Statistically significant differences were detected between group 1 and group 2 in the mean pain score on VAS (2.53 ± 1.34 vs 1.63 ± 1.09, P=0.002, Mann-Whitney U test), mean postprocedural State Anxiety Inventory pain score (39.4 ± 6.5 vs 34.5 ± 5.8), and postprocedural pulse rate (79.8 ± 5.5 vs 76.0 ± 7.3) (P<0.001 for both, t test). Patients who listened to their preferred music experienced less discomfort and lower anxiety at cystoscopy. Patient age, duration of the procedure, preprocedural STAI-S, and preprocedural pulse rate of each group were comparable. Listening to preferred music during flexible cystoscopy is an easy way to improves male patients' comfort and reduce their anxiety. It could be recommended for male patients.

Testosterone (T) is commonly administered intramuscularly to treat hypogonadal males and female-to-male (FTM) transgender patients. However, these injections can involve significant discomfort and may require arrangements for administration by others. We assessed whether T could be administered effectively and safely subcutaneously as an alternative to intramuscular (IM) injections. Retrospective cohort study. Outpatient reproductive endocrinology clinic at an academic medical center. Sixty-three FTM transgender patients aged >18 years electing to receive subcutaneous (SC) T therapy for sex transition were included. Fifty-three patients were premenopausal. Patients were administered T cypionate or enanthate weekly at an initial dose of 50 mg. Dose was adjusted if needed to achieve serum total T levels within the normal male range. Serum concentrations of free and total T and total estradiol (E2), masculinization, and surveillance for reactions at injection sites. Serum T levels within the normal male range were achieved in all 63 patients with doses of 50 to 150 mg (median, 75/80 mg). Therapy was effective across a wide range of body mass index (19.0 to 49.9 kg/m2). Minor and transient local reactions were reported in 9 out of 63 patients. Among 53 premenopausal patients, 51 achieved amenorrhea and 35 achieved serum E2 concentrations <50 pg/mL. Twenty-two patients were originally receiving IM and switched to SC therapy. All 22 had a mild (n = 2) or marked (n = 20) preference for SC injections; none preferred IM injections. Our observations indicate that SC T injections are an effective, safe, and well-accepted alternative to IM T injections. Copyright © 2017 Endocrine Society

At present only a small number of studies have investigated psychiatric comorbidity in disc surgery patients. Objectives of this study are (1) to examine the prevalence rate of comorbid affective, anxiety, and substance-related disorders in nucleotomy patients in comparison to the German general population and (2) to investigate associations between psychiatric comorbidity and socio-demographic and illness-related characteristics. The study refers to 349 consecutive disc surgery patients (response rate 87%) between the age of 18 and 55 years. The final study sample consists of 239 lumbar and 66 cervical nucleotomy patients. Face-to-face interviews were conducted approximately 3.45 days (SD 3.170) after disc surgery, during hospital stay. Psychiatric comorbidity was assessed by means of the Composite International Diagnostic Interview (CIDI-DIA-X). The corresponding data of the German general population were derived from the German National Health Interview and Examination Survey (GHS). 12-Month prevalence rates of any affective, anxiety or substance-related disorders range between 33.7% in cervical and 23.5% in lumbar disc surgery patients. Four-week prevalence rates of any affective, anxiety or substance disorder vary between 13.2% in cervical and 14.0% in lumbar nucleotomy patients. Disc surgery patients suffer more often from affective disorders and illicit substance abuse than the general population. Significant associations were found between psychiatric comorbidity and gender, as well as pain intensity. Disc surgery patients show a higher risk to suffer from mental disorders than the general population. The assessment of psychiatric distress and the assistance by mental health professionals should be considered during hospital and rehabilitation treatment.

Impulsivity has been shown to be a major variable in the etiology of suicide and aggression, but has not been researched as much in the schizophrenic population, which is characterized by serious suicide and aggression risks. 68 male schizophrenia patients responded to a battery of measures including the Positive and Negative Syndrome Scale (PANSS), the impulsivity control scale (IS), the Suicide Risk Scale (SRS) and the Overt Aggression Scale. We divided our subjects into those who received scores above and below the median on the IS. The high-impulsivity group had higher present and past rates of suicidal ideation and showed a trend for more lifetime suicidal attempts than the low-impulsivity group. The impulsivity score correlated positively with the SRS score and with some of the scores of the PANSS (the positive symptoms score, the general psychopathology score and the total score). A multiple regression analysis revealed that an older age, higher levels of aggression, high impulsivity and an elevated score on the general psychopathology subscale of the PANSS contributed positively and significantly to the explained variance of the SRS. Our study supports the contention that high impulsivity in schizophrenia patients is significant in the etiology of suicide in schizophrenia. However, the relationship between impulsivity and aggression in schizophrenia patients, and also the amelioration of impulsivity by pharmacological interventions, require further study.

OBJECTIVE: To assess whether female primary care physicians' reported coverage of patients eligible for certain preventive care strategies differs from male physicians' reported coverage. DESIGN: A mailed survey. SETTING: Primary care practices in southern Ontario. PARTICIPANTS: All primary care physicians who graduated between 1972 and 1988 and practised in a defined geographic area of Ontario were selected from the Canadian Medical Association's physician resource database. Response rate was 50%. MAIN OUTCOME MEASURES: Answers to questions on sociodemographic and practice characteristics, attitudes toward preventive care, and perceptions about preventive care behaviour and practices. RESULTS: In general, reported coverage for Canadian Task Force on the Periodic Health Examination's (CTFPHE) A and B class recommendations was low. However, more female than male physicians reported high coverage of women patients for female-specific preventive care measures (i.e., Pap smears, breast examinations, and mammography) and for blood pressure measurement. Female physicians appeared to question more patients about a greater number of health risks. Often, sex of physician was the most salient factor affecting whether preventive care services thought effective by the CTFPHE were offered. However, when evidence for effectiveness of preventive services was equivocal or lacking, male and female physicians reported similar levels of coverage. CONCLUSION: Female primary care physicians are more likely than their male colleagues to report that their patients eligible for preventive health measures as recommended by the CTFPHE take advantage of these measures.

Male vocal competition is dynamic and strongly affected by social contexts in music frogs.

Male-male vocal competition in anuran species is critical for mating success; however, it is also highly time-consuming, energetically demanding and likely to increase predation risks. Thus, we hypothesized that changes in the social context would cause male vocal competition to change in real time in order to minimize the costs and maximize the benefits of competition. To test this hypothesis, we assessed the effect of repeating playbacks of either white noise (WN) or male advertisement calls on male call production in the Emei music frog (Babina daunchina), a species in which males build mud-retuse burrows and call from within these nests. Previous studies have shown that calls produced from inside burrows are highly sexually attractive (HSA) to females while those produced outside nests are of low sexual attractiveness (LSA). Results showed that most subjects called responsively after the end of WN playbacks but before the onset of conspecific call stimuli although call numbers were similar, indicating that while males adjusted competitive patterns according to the biological significance of signals, their competitive motivation did not change. Furthermore, these data indicate that the frogs had evolved the ability of interval timing. Moreover, when the inter-stimulus interval (ISI) between playbacks was varied, the subjects preferentially competed with HSA calls when the ISI was short (<4 s) but responded equally to HSA and LSA calls if the ISI was long (≥4 s), suggesting that males allocate competitive efforts depending on both the perceived sexual attractiveness of rivals and the time available for calling. Notably, approximately two-thirds of male calls occurred in response to HSA calls, a preference rate comparable to that previously found for females in phonotaxis experiments and consistent with the idea that the mechanisms underlying both the male's competitive responses to rivals and the female's preferences toward potential mates coevolved under the

Analysis of relative importance of side effects of anticancer therapy is extremely useful in the process of clinical decision making. There is evidence that patients' perception of the side effects of anticancer treatments changes over time. Aim of this study was to evaluate the cancer patients' perceptions of physical and non-physical side effects of contemporary anticancer therapy. Four hundred and sixty-four patients entered the study (153 men and 311 women). Participants were asked to rank their side effects in order of distress by using two sets of cards naming physical and non-physical effects, respectively. Influencing factors, including treatment and patient characteristics, were also analysed. Patients ranked the non-physical side effect 'Affects my family or partner' first. 'Constantly tired' and 'Loss of hair' were ranked second and third, respectively. Significant differences from previous studies on this topic emerged. In particular, 'Vomiting', a predominant concern in previous studies, almost disappeared, whereas 'Nausea' and 'Loss of hair' remained important side effects in the patients' perception. Interestingly, marital status was predominant in driving patients' perception, being associated with several side effects ('Constantly tired', 'Loss of appetite', 'Affects my work/Home duties', 'Affects my social activities', 'Infertility'). Other significant factors influencing patient's perception of side effects included age, disease characteristics and ongoing anticancer therapy. This study provided information on current status of patients' perceptions of side effects of anticancer treatment. These results could be used in pre-treatment patient education and counselling.

In order to obtain references for adequate diagnostic procedures of depressive syndromes in cancer patients, the present study analyzes first the prevalence of somatic, emotional, and cognitive symptoms of depression. In a second part, the ability of diagnostic procedures to discriminate between patients with and without comorbid affective disorder is investigated. From a cross-sectional survey investigating comorbid mental disorders in cancer patients with standardized clinical assessment, a subsample of 71 patients with current affective disorders and depressive symptoms according to the Diagnostic and Statistic Manual of Mental Disorders, 4th edition (DSM-IV) were analyzed. In addition to patients' symptom patterns, a discriminant analysis including all depressive symptoms was conducted. Cognitive symptoms are less prevalent in cancer patients than somatic and emotional symptoms. Loss of interest discriminated best between patients with and without diagnosis of comorbid affective disorder. Additionally, decreased energy and fatigue proved to have discriminatory value. Cognitive symptoms should receive special attention in diagnostic procedures for affective disorders in cancer patients. In spite of possible symptom overlap with the cancer disease and its treatment, fatigue proves to be a useful criteria for diagnosis of depression.

Evolutionary Influences on Attribution and Affect

Evolutionary theory was applied to Reeder and Brewer's schematic theory and Trafimow's affect theory to extend this area of research with five new predictions involving affect and ability attributions, comparing morality and ability attributions, gender differences, and reaction times for affect and attribution ratings. The design included a 2 (Trait Dimension Type: HR, PR) × 2 (Behavior Type: morality, ability) × 2 (Valence: positive, negative) × 2 (Replication: original, replication) × 2 (Sex: female or male actor) × 2 (Gender: female or male participant) × 2 (Order: attribution portion first, affect portion first) mixed design. All factors were within participants except the order and participant gender. Participants were presented with 32 different scenarios in which an actor engaged in a concrete behavior after which they made attributions and rated their affect in response to the behavior. Reaction times were measured during attribution and affect ratings. In general, the findings from the experiment supported the new predictions. Affect was related to attributions for both morality and ability related behaviors. Morality related behaviors received more extreme attribution and affect ratings than ability related behaviors. Female actors received stronger attribution and affect ratings for diagnostic morality behaviors compared to male actors. Male and female actors received similar attribution and affect ratings for diagnostic ability behaviors. Diagnostic behaviors were associated with lower reaction times than non-diagnostic behaviors. These findings demonstrate the utility of evolutionary theory in creating new hypotheses and empirical findings in the domain of attribution. PMID:29312092

In previous reports concerning the association between sex disparity and age, gastric cancer (GC) patients were simply divided into younger and older groups by age. We analyzed the age trend of the male to female sex ratio (MFSR) in GC based on patient sequential age in order to observe the changing process of MFSR with age. One thousand seven hundred fifty-one surgical gastric adenocarcinoma patients aged 26 to 85 years were investigated between January 1996 and December 2010. The patients were grouped by age intervals of 5 years. The Cochran-Armitage trend test was used to determine how the MFSR changed with age. The median age of the 1,751 patients with GC was 60 years (26 to 85 years). There were 1,334 male and 417 female patients (MFSR was 3.20). Cochran-Armitage trend test analysis showed that total MFSR increased significantly with age (Z = 5.964, P < 0.0001). Further studies on age groups of 26 to 60 years and 61 to 85 years were conducted. The trend test showed that MFSR increased significantly with age from 26 to 60 years (Z = 7.433, P < 0.0001). However, MFSR did not increase in ages 61 to 85 years (Z = -0.607, P = 0.544). MFSR in GC presented an increasing trend until 60 years of age. The male GC patients showed an increasing tendency, and female GC patients showed a decreasing tendency with age. This trend reached a plateau phase after 60 years of age.

Behavioural symptoms are common in moderate to severe Alzheimer's disease (AD) and are improved by memantine with the most pronounced effect on agitation/aggression. Dextromethorphan in combination with quinidine is the only drug approved by US Food and Drug Administration for the treatment of pseudobulbar affect (PBA) on the basis of efficacy in patients with multiple sclerosis or amyotrophic lateral sclerosis. The aim of our study was to evaluate the efficacy of memantine on PBA in patients with AD. In a prospective, double-blind, case-control study to assess PBA with pathological laughter and crying scale patients were administered memantine (final dose of 20 mg daily) or citalopram (20 mg once daily), each for 10 weeks. The number of episodes of involuntary emotional expression, Neuropsychiatric Inventory (NPI) and Overt Aggression Scale-Modified (OAS-M) total scores were also recorded. Furthermore, the platelet serotonin (5-HT) concentration was measured. Although memantine had beneficial effects on PBA, it also had a crucial impact on behavioural symptoms, especially aggression and agitation (to an average of 3.5 times higher end-point scores on OAS-M and increase of NPI total scores for an average of 114% of initial value). Therefore, the study was prematurely stopped. In addition, we had evidenced a drop of platelet 5-HT concentration (to an average of 73% of initial value). Surprisingly, our research showed the opposite action of memantine on neuropsychiatric symptoms as expected. In a limited number of AD patients with PBA, memantine had a beneficial effect on involuntary emotional expression, but it potentiated agitation/aggression, irritability and caused a crucial drop of the platelet 5-HT concentration.

What are the primary causes of severe male factor infertility? Although 40% of all patients showed primary causes of infertility, which could be subdivided into three groups based on the severity of their effect, ~75% of oligozoospermia cases remained idiopathic. There are few large-scale epidemiological studies analyzing the causes of male factor infertility. A prospective clinical-epidemiological study was conducted at the Andrology Centre, Tartu University Hospital between 2005 and 2013, recruiting male partners of couples failing to conceive a child for over ≥12 months. Among 8518 patients, 1737 (20.4%) were diagnosed with severe male factor infertility. A reference group of fertile controls was comprised of 325 partners of pregnant women. The mean age of infertility patients and fertile controls was 33.2 ± 7.3 and 31.7 ± 6.3 years, respectively. All participants were examined using a standardized andrology workup, accompanied by a structured medical interview. Hormonal analysis included serum FSH, LH and testosterone. Semen quality was determined in accordance to the World Health Organization recommendations. Cases with spermatozoa concentrations of ≤5 million/ml were screened for chromosomal aberrations and Y-chromosomal microdeletions. The primary cause of infertility was defined for 695 of 1737 patients (~40%). The analyzed causal factors could be divided into absolute (secondary hypogonadism, genetic causes, seminal tract obstruction), severe (oncological diseases, severe sexual dysfunction) and plausible causal factors (congenital anomalies in uro-genital tract, acquired or secondary testicular damage). The latter were also detected for 11 (3.4%) men with proven fertility (diagnoses: unilateral cryptorchidism, testis cancer, orchitis, mumps orchitis). The causal factors behind the most severe forms of impaired spermatogenesis were relatively well understood; causes were assigned: for aspermia in 46/46 cases (100%), for azoospermia in 321

To compare the existence of gonial cortical bone thickness, antegonial index, mandibular canal bone resorption and gonial angle values and pathologies like ground-glass appearance in jawbones and brown tumor in male patients undergoing dialysis due to chronic renal failure and men from the healthy control group on panoramic radiographs. Panoramic radiographs were taken from 80 male individuals in total (40 normal and 40 dialysis patients). Values obtained from the right and left sides of the mandible were summed and their means were calculated. Gonial cortical thickness, antegonial index and gonial angle values were assessed with the Student's t-test, mandibular canal wall resorption with the Chi-square test, and pathologies such as ground-glass appearance and Brown tumor as "available" or "not available." Statistically significant differences were observed among the antegonial index (P < 0.001), gonial cortical bone thickness (P < 0.001), and gonial angle (P < 0.001) values of study and control groups. Besides, mandibular canal wall resorption (P < 0.001) was also statistically significant. In the study group, pathologies with ground-glass appearance were encountered in mandible, but no radiographic findings were observed similar to brown tumor. Compared to the control group, decreases were found in gonial cortical bone thicknesses, antegonial index values, mandibular canal wall resorption, and gonial angle values of the patients receiving dialysis treatment due to chronic renal failure. Although it is not statistically significant, pathology with ground-glass appearance was detected in a patient, but no pathologies like brown tumor were observed. These findings from patients with chronic renal failure must be evaluated in panoramic radiography.

Bone metabolism is affected by mechanical, genetic, and environmental factors and plays a major role in osteoporosis. Nevertheless, the influence of environmental pollution on the occurrence of osteoporosis is still unclear and controversial. In this context, heavy metals are the most important pollutants capable to affect bone mass. The aim of this study was to investigate whether heavy metals accumulation in bone tissues could be related to the altered bone metabolism and architecture of osteoporotic patients. To this end, we analyzed 25 bone head biopsies osteoporotic patients and 25 bone head biopsies of osteoarthritic patients. Moreover we enrolled 15 patients underwent hip arthroplasty for high-energy hip fracture or osteonecrosis of the femoral head as a control group. Bone head biopsies were studied by BioQuant-osteo software, scanning electron microscopy and Energy Dispersive X-ray microanalysis. We found a prevalence of lead, cadmium and chromium accumulation in osteoporotic patients. Noteworthy, high levels of sclerostin, detected by immunohistochemistry, correlate with the accumulation of heavy metal found in the bone of osteoporotic patients, suggesting a molecular link between heavy metal accumulation and bone metabolism impairment. In conclusion, the presence of heavy metals into bone shed new light on the comprehension of the pathogenesis of osteoporosis since these elements could play a non redundant role in the development of osteoporosis at cellular/molecular and epigenetic level. Nevertheless, in vivo and in vitro studies need to better elucidate the molecular mechanism in which heavy metals can participate to osteoporosis. © 2016 Wiley Periodicals, Inc.

Sleep disorders and depression are prevalent conditions in patients with end-stage kidney disease. These co-morbidities have significant overlap and compounded morbidity and mortality burden. This overlap presents challenges to optimal clinical assessment and treatment. The goal of this study was to assess the prevalence of sleep disturbance in patients on maintenance haemodialysis, and to assess the impact of depressive affect. This was a single-site, single group, cross-sectional study of 69 English-speaking patients undergoing maintenance haemodialysis. Self-reported assessments included those of sleep quality (Pittsburgh Sleep Quality Index), depression (Beck Depression Inventory), daytime sleepiness (Epworth's Sleepiness Scale), a dialysis-specific sleep questionnaire, and standard laboratory values. No objective sleep information was collected. All participants were well dialysed, and represented all four daily shifts. Fifty-eight per cent reported clinically significant sleep difficulty, with elevated yet sub-threshold daytime sleepiness. Mean depressive affect was also elevated, yet sub-diagnostic and was positively correlated with increased age. Participants scoring above the diagnostic threshold for depression had significantly more disturbed sleep quality, more daytime sleepiness and had more problems sleeping due to restless leg syndrome than people with minimal depressive affect. Poor sleep quality is prevalent in patients on maintenance haemodialysis, and is associated with increased daytime sleepiness. Depression further compounds this relationship, and is significantly associated with increased daytime sleepiness and restless leg syndrome. © 2016 European Dialysis and Transplant Nurses Association/European Renal Care Association.

Although increasing attention has been paid to plant adaptation to soil heavy metal contamination, competition and neighbor effects have been largely overlooked, especially in dioecious plants. In this study, we investigated growth as well as biochemical and ultrastructural responses of Populus cathayana Rehder females and males to cadmium (Cd) stress under different sexual competition patterns. The results showed that competition significantly affects biomass partitioning, photosynthetic capacity, leaf and root ultrastructure, Cd accumulation, the contents of polyphenols, and structural and nonstructural carbohydrates. Compared with single-sex cultivation, plants of opposite sexes exposed to sexual competition accumulated more Cd in tissues and their growth was more strongly inhibited, indicating enhanced Cd toxicity under sexual competition. Under intrasexual competition, females showed greater Cd accumulation, more serious damage at the ultrastructural level and greater reduction in physiological activity than under intersexual competition, while males performed better under intrasexual competition than under intersexual competition. Males improved the female microenvironment by greater Cd uptake and lower resource consumption under intersexual competition. These results demonstrate that the sex of neighbor plants and competition affect sexual differences in growth and in key physiological processes under Cd stress. The asymmetry of sexual competition highlighted here might regulate population structure, and spatial segregation and phytoremediation potential of both sexes in P. cathayana growing in heavy metal-contaminated soils. © The Author 2016.

Melatonin and male reproduction.

PubMed

Li, Chunjin; Zhou, Xu

2015-06-15

Melatonin is a neurohormone secreted by the pineal gland whose concentrations in the body are regulated by both the dark-light and seasonal cycles. The reproductive function of seasonal breeding animals is clearly influenced by the circadian variation in melatonin levels. Moreover, a growing body of evidence indicates that melatonin has important effects in the reproduction of some non-seasonal breeding animals. In males, melatonin affects reproductive regulation in three main ways. First, it regulates the secretion of two key neurohormones, GnRH and LH. Second, it regulates testosterone synthesis and testicular maturation. Third, as a potent free radical scavenger that is both lipophilic and hydrophilic, it prevents testicular damage caused by environmental toxins or inflammation. This review summarizes the existing data on the possible biological roles of melatonin in male reproduction. Overall, the literature data indicate that melatonin affects the secretion of both gonadotropins and testosterone while also improving sperm quality. This implies that it has important effects on the regulation of testicular development and male reproduction. Copyright © 2015. Published by Elsevier B.V.

Brain-derived neurotrophic factor (BDNF) and oxidative stress may play a role in patients with heroin dependence. The aim of this study was to investigate the serum levels and activities of BDNF and oxidative stress markers, such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), thiobarbituric acid reactive substances (TBARS), protein carbonyl content (PCC), and 8-hydroxy 2'-deoxyguanosine (8-OHdG), in heroin-dependent patients undergoing methadone maintenance treatment (MMT). 60 heroin-dependent male MMT patients and 30 healthy males were recruited for this study. The serum BDNF and oxidative stress markers of these subjects were measured with assay kits. Analyses of covariance (ANCOVAs) with age and body mass index adjustments indicated that the serum levels of BDNF in the MMT patients were significantly higher than those in the healthy controls (F=5.169; p=0.026). However, there were no significant differences between the heroin-dependent patients and the healthy controls in the serum levels or activities of oxidative stress markers (p>0.05). In conclusion, our results suggest that MMT increases BDNF levels in heroin-dependent patients, and that patients undergoing MMT might be in a balanced state of reduced oxidation.

The purpose of this study was to investigate whether administration of the regimen of gossypol at 12 mg/kg/day combined with methyltestosterone at 20 mg/kg/day and ethinylestradiol at 100 microg/kg/day for a long term of twenty-four weeks could affect the existence and differentiation of rat spermatogonial stem cell. This was assessed by conducting TdT-mediated dUTP nick end-labeling detection, spermatogonial stem cell transplantation and fertility recovery evaluation. Our results showed that spontaneous apoptosis was observed in normal rats' testes from the control group with an apoptotic index (AI) average of 10.24+/-1.52. In the regimen-treated group, the predominant apoptotic cells were spermatocytes and spermatids in the seminiferous tubules. Spermatogonia were not apoptotic (AI averaged 113.42+/-13.24). Two to three months after transplantation of spermatogonial stem cells isolated from regimen-treated rats into recipient nude mice, elongated rat spermatids were identified in the seminiferous tubules of recipient nude mice. Six weeks after withdrawal of the administration, fertility of the regimen-treated rats was recovered compared with that of the control group. The number of litters produced by females mated with regimen-treated males averaged 9.88+/-0.166 matched 10.30+/-0.171 of control group and the litters of the first generation appeared to be normal. These results indicated that the administration of this regimen did not affect the existence and differentiation potential of spermatogonial stem cells of the regimen-treated rats.

Nicotine dependence has been suggested to be related to reinforcement sensitivity, which encompasses behavioral predispositions either to avoid aversive (behavioral inhibition) or to approach appetitive (behavioral activation) stimuli. Reinforcement sensitivity may shape motives for nicotine use and offer potential targets for personalized smoking cessation therapy. However, little is known regarding how reinforcement sensitivity is related to motivational processes implicated in the maintenance of smoking. Additionally, women and men differ in reinforcement sensitivity, and such difference may cause distinct relationships between reinforcement sensitivity and motivational processes for female and male smokers. In this study, we characterized reinforcement sensitivity in relation to affect, smoking-related reinforcement motives, and affective responses, using self-report and psychophysiological measures, in over 200 smokers before treating them. The Behavioral Inhibition/Activation Scales (BIS/BAS; Carver & White, 1994) was used to measure reinforcement sensitivity. In female and male smokers, BIS was similarly associated with negative affect and negative reinforcement of smoking. But positive affect was positively associated with BAS Drive scores in male smokers, and this association was reversed in female smokers. BIS was positively associated with corrugator electromyographic reactivity towards negative stimuli and left frontal electroencephalogram alpha asymmetry. Female and male smokers showed similar relationships for these physiological measures. These findings suggest that reinforcement sensitivity underpins important motivational processes (e.g., affect), and gender is a moderating factor for these relationships. Future personalized smoking intervention, particularly among more dependent treatment-seeking smokers, may experiment to target individual differences in reinforcement sensitivity. PMID:25621416

Primary iron overload (IO) is commonly associated with mutations in the hereditary hemochromatosis gene (HFE). Nonetheless, other genetic variants may influence the development of IO beyond HFE mutations. There is a single nucleotide polymorphism (SNP) at - 174 G>C of the interleukin (IL)-6 gene which might be associated with primary IO. Our aim was to study the association between the SNP - 174 G>C gene promoter of IL-6 and primary IO in middle-aged male patients. We studied 37 men with primary IO diagnosed by liver histology. Controls were age-matched male volunteers (n = 37). HFE mutations and the SNP - 174 G>C gene promoter of IL-6 were evaluated by PCR-RFLP. Logistic regression was used to evaluate the association between primary IO and SNP - 174 G>C gene promoter of IL-6. Patients and control subjects were in Hardy-Weinberg equilibrium for the SNP - 174 G>C gene promoter of IL-6 (p = 0.17). Significantly different genotype frequencies were observed between patients (43% CC, 43% CG, and 14% GG) and control subjects (10% CC, 41% CG, and 49% GG) (OR = 4.09, 95% CI = 2.06-8.13; p < 0.0001). The multiple logistic regression analysis showed that IO was significantly associated with CC homozygosis in the SNP - 174 G>C gene promoter of IL-6 (OR = 6.3, 95% CI = 1.9-21.4; p < 0.005) in a model adjusted by age and body mass index. In conclusion, CC homozygosis in the SNP - 174 G>C gene promoter of IL-6 can be proposed as one of the gene variants influencing iron accumulation in male adults with HFE mutations. Studies in larger cohorts are warranted.

Study Objectives: To measure differences in functional status between men and women presenting with sleep-related health problems. Methods: A retrospective clinical audit of 744 Australian patients across 7 private general practices between April 2013 and January 2015 was conducted. Patients completed an electronic survey as part of their routine consultation, which included the Epworth Sleepiness Scale (ESS), the Functional Outcomes of Sleep Questionnaire 10 (FOSQ-10), and other questions relating to the effect of their sleep problem. The proportion of males and females with ESS and FOSQ-10 scores associated with disorders of daytime sleepiness and burden of symptoms due to sleepiness, respectively, were compared, as well as reported differences between the sexes in memory, concentration, issues with relationships, feeling depressed, and trouble sleeping. Results: On presentation, females were more likely to have sleeping disorders associated with daytime sleepiness (median ESS score of 9 for females versus 8 for males, P = .038; proportion ESS > 9 was 49.0% for females versus 36.9% for males, P = .003). Women were also more likely to report an increased burden of symptoms due to sleepiness compared to men, as shown by lower FOSQ-10 scores (P < .001). Secondary outcome measures showed that females were more likely to feel excessively tired and depressed, have difficulties with memory and concentration, and have trouble sleeping at night. Snoring kept partners awake in roughly the same proportion of males and females, and a larger proportion of the partners of males were forced out of the room. Conclusions: Sleep-related health issues both manifest in and affect the lives of males and females differently. Sleep health professionals should recognize these differences on all levels of disease prevention and health promotion from patient education, to diagnosis and management to improve quality of life for those with sleep-related health problems.

With increasing evidence to support its practice, acupuncture has been integrated within many hospitals around the world. The purpose of this study is to understand the factors affecting decision making of patients as they select acupuncture treatment for their medical conditions and symptoms within a public hospital. A qualitative study consisting of in depth interviews with 14 patients was conducted. All patients attended an acupuncture clinic within a public hospital. Data collected was analysed via thematic analysis. Four main factor groups affecting decision making of patients were identified- factors affecting the level and value of patient-centric care, the confidence and trust patients place within the acupuncture service, the presence of collaborative efforts between acupuncturists and Western medicine practitioners, and the knowledge, culture and belief society has regarding the role of acupuncture and Western medicine. All participants interviewed had more than one factor group present as enablers toward their eventual selection of acupuncture for ailment management. It was also noted that although the majority of participants had sufficient knowledge regarding acupuncture, there were a select few who had misperceptions or no knowledge regarding certain aspects of acupuncture. There may be certain patterns in the way patients choose to utilise acupuncture services in public hospitals. Further studies should also be carried out in other public hospitals to analyse the factor groups identified further.

Objective. The clinical factors associated with sperm DNA fragmentation (SDF) were investigated in male patients with infertility. Materials and Methods. Fifty-four ejaculates from infertile Japanese males were used. Thirty-three and twenty-one were from the patients with varicoceles and idiopathic causes of infertility, respectively. We performed blood tests, including the serum sex hormone levels, and conventional and computer-assisted semen analyses. The sperm nuclear vacuolization (SNV) was evaluated using a high-magnification microscope. The SDF was evaluated using the sperm chromatin dispersion test (SCDt) to determine the SDF index (SDFI). The SDFI was compared with semen parameters and other clinical variables, including lifestyle factors. Results. The SDFI was 41.3 ± 22.2% (mean ± standard deviation) and did not depend on the cause of infertility. Chronic alcohol use increased the SDFI to 49.6 ± 23.3% compared with 33.9 ± 18.0% in nondrinkers. The SDFI was related to adverse conventional semen parameters and sperm motion characteristics and correlated with the serum FSH level. The SNV showed a tendency to increase with the SDFI. The multivariate analysis revealed that the sperm progressive motility and chronic alcohol use were significant predictors of the SDF. Conclusion. The SCDt should be offered to chronic alcohol users and those with decreased sperm progressive motility. PMID:25165747

Precursors of neuroactive substances can be obtained from dietary sources, which can affect the resulting production of such substances in the brain. In social species, an intake of the precursor in food could be controlled by social interactions. To test the effects of dietary tyrosine on the brain dopamine levels in social insect colonies, male and worker honeybees were fed tyrosine or royal jelly under experimental conditions and the brain levels of dopamine and its metabolite were then measured. The results showed that the levels of dopamine and its metabolite in the brains of 4- and 8-day-old workers and 8-day-old males were significantly higher in tyrosine-fed bees than in control bees, but the levels in 4-day-old males were not. The brain levels of dopamine and its metabolite in 4- and 8-day-old males and workers were significantly higher in royal jelly-fed bees than in control bees, except for one group of 4-day-old workers. Food exchanges with workers were observed in males during 1-3 days, but self-feedings were also during 5-7 days. These results suggest that the brain levels of dopamine in males can be controlled by an intake of tyrosine in food via exchanging food with nestmates and by self-feeding.

Parental bonding in males with adjustment disorder and hyperventilation syndrome

PubMed Central

2012-01-01

Background The purpose of the study was to identify the style of parental bonding and the personality characteristics that might increase the risk of hyperventilation and adjustment disorder. Methods A total of 917 males were recruited, 156 with adjustment disorder and hyperventilation syndrome (AD + HY), 273 with adjustment disorder without hyperventilation syndrome (AD–HY), and 488 healthy controls. All participants completed the Parental Bonding Instrument, Eysenck Personality Questionnaire, and Chinese Health Questionnaire. Results Analysis using structural equation models identified a pathway relationship in which parental bonding affected personality characteristics, personality characteristics affected mental health condition, and mental health condition affected the development of hyperventilation or adjustment disorder. Males with AD–HY perceived less paternal care, and those with AD + HY perceived more maternal protection than those with adjustment disorder and those in the control group. Participants with AD–HY were more neurotic and less extroverted than those with AD + HY. Both groups showed poorer mental health than the controls. Conclusions Although some patients with hyperventilation syndrome demonstrated symptoms of adjustment disorder, there were different predisposing factors between the two groups in terms of parental bonding and personality characteristics. This finding is important for the early intervention and prevention of hyperventilation and adjustment disorder. PMID:22672223

Patient and disease factors affecting the choice and adherence to active surveillance.

Dall'Era, Marc A

2015-05-01

Treatment decisions for low-risk prostate cancer are arguably some of the most challenging in oncology. Active surveillance has emerged as an important option for many men with tumors estimated to have a low metastatic potential. Multiple complex patient and physician factors affect the recommendation, selection, and adherence to active surveillance. While baseline clinical criteria are used to identify candidates for this approach, it is important to identify and understand other forces that may influence the management of prostate cancer with active surveillance. Patient perceptions and acceptance of active surveillance have improved over time. Treatment decisions for prostate cancer are strongly associated with physician recommendations, and a high-quality relationship between the patient and his healthcare system is critical to successful active surveillance. Patient understanding of prostate cancer and consistency of information received from separate physicians can affect a decision to pursue active surveillance. Psychological symptoms, most notably regarding anxiety and distress, can affect adherence to active surveillance over time. In general, anxiety for men on active surveillance is low, and lifestyle interventions and self-management strategies may be helpful for increasing quality of life and limiting abandonment of active surveillance in the absence of disease progression. Multiple factors may affect the decision for and adherence to active surveillance for prostate cancer. It is important for both physicians and patients to be aware of these issues and work towards individualized approaches and interventions as needed to increase adoption of active surveillance in the future.

In Peru, there are few studies on male sex workers (MSWs), and existing studies explore limited subgroups or offer limited information about MSWs' perspectives. This study provides in-depth perspectives from 40 MSWs who work in downtown Lima (Cercado) and in surrounding urban neighborhoods (non-Cercado) through interviews on their identities, lives, and HIV/STI (sexually transmitted infection) risks and vulnerabilities. Findings are that entry into sex work links economy and affection, particularly among Cercado MSWs. Continued sex work cements this link, making it difficult to exit sex work and establish goals. Ties between economics and affections influence MSWs' perceived HIV/STI risks, vulnerabilities, and prevention practices. Although Cercado MSWs report higher HIV/STI risks and vulnerabilities than non-Cercado peers, they report fewer prevention practices given inability to buy condoms and acceptance of client offers of higher payment, especially clients they feel affection for. MSWs need support to strengthen their self-perceptions and define and pursue their goals in order to improve their HIV/STI prevention practices, health, and well-being. © The Author(s) 2013.

Male hypogonadism is defined as the deficiency of testosterone or sperm production synthesized by testicles or the deficiency of both. The reasons for hypogonadism may be primary, meaning testicular or secondary, meaning hypothalamohypophyseal. In hypogonadotropic hypogonadism (HH), there is indeficiency in gonadotropic hormones due to hypothalamic or hypophyseal reasons. Gonadotropin-releasing hormone (GnRH) is an important stimulant in releasing follicular stimulant hormone (FSH), mainly luteinizing hormone (LH). GnRH omitted is under the effect of many hormonal or stimulating factors. Kisspeptin is present in many places of the body, mostly in hypothalamic anteroventral periventricular nucleus and arcuate nucleus. Kisspeptin has a suppressor effect on the metastasis of many tumors such as breast cancer and malign melanoma metastases, and is called "metastin" for this reason. Kisspeptin is a strong stimulant of GnRH. In idiopathic hypogonadotropic hypogonadism (IHH) etiology, there is gonadotropic hormone release indeficiency which cannot be clearly described. A total of 30 male hypogonatropic hypogonadism diagnosed patients over 30 years of age who have applied to Haydarpasa Education Hospital Endocrinology and Metabolic Diseases Service were included in the study. Compared to the control group, the effect of kisspeptin on male patients with hypogonatropic hypogonadism and on insulin resistance developing in hypogonadism patients was investigated in our study. A statistically significant difference was detected between average kisspeptin measurements of the groups (p < 0.01). Kisspeptin measurement of the cases in the patient group were detected significantly high. No statistically significant relation was detected among kisspeptin and LH/FSH levels. Although a positive low relation was detected between kisspeptin measurements of patient group cases and homeostasis model assessment of insulin resistance (HOMA-IR) measurements, this relation was statistically

Female sticklebacks use male coloration in mate choice and hence avoid parasitized males

AN important problem in evolutionary biology since the time of Darwin has been to understand why females preferentially mate with males handicapped by secondary sexual ornaments1-3. One hypothesis of sexual selection theory is that these ornaments reliably reveal the male's condition4-6, which can be affected for example by parasites4,7-13. Here we show that in the three-spined stickleback (Gasterosteus aculeatus) the intensity of male red breeding coloration positively correlates with physical condition. Gravid females base their active mate choice on the intensity of the male's red coloration. Choice experiments under green light prevent the use of red colour cues by females, and males that were previously preferred are now chosen no more than randomly, although the courtship behaviour of the males remains unchanged. Parasitieation causes a deterioration in the males' condition and a decrease in the intensity of their red coloration. Tests under both lighting conditions reveal that the females recognize the formerly parasitized males by the lower intensity of their breeding coloration. Female sticklebacks possibly select a male with a good capacity for paternal care14 but if there is additive genetic variation for parasite resistance, then they might also select for resistance genes, as proposed by Hamilton and Zuk4.

Infertility is a major and largely incurable disease caused by disruption and loss of germ cells. It affects 10-15% of couples, and male factor accounts for half of the cases. To obtain human male germ cells 'especially functional spermatids' is essential for treating male infertility. Currently, much progress has been made on generating male germ cells, including spermatogonia, spermatocytes, and spermatids, from various types of stem cells. These germ cells can also be used in investigation of the pathology of male infertility. In this review, we focused on advances on obtaining male differentiated germ cells from different kinds of stem cells, with an emphasis on the embryonic stem (ES) cells, the induced pluripotent stem (iPS) cells, and spermatogonial stem cells (SSCs). We illustrated the generation of male differentiated germ cells from ES cells, iPS cells and SSCs, and we summarized the phenotype for these stem cells, spermatocytes and spermatids. Moreover, we address the differentiation potentials of ES cells, iPS cells and SSCs. We also highlight the advantages, disadvantages and concerns on derivation of the differentiated male germ cells from several types of stem cells. The ability of generating mature and functional male gametes from stem cells could enable us to understand the precise etiology of male infertility and offer an invaluable source of autologous male gametes for treating male infertility of azoospermia patients. © 2014 Society for Reproduction and Fertility.

To determine the prevalence of negative symptoms and to examine secondary sources of influence on negative symptoms and the role of specific negative symptoms in delay associated with seeking treatment in first episode non-affective psychosis. One hundred and ten patients who met Diagnostic Statistical Manual-IV (DSM-IV) criteria for a first episode of schizophrenia spectrum psychoses were rated for assessment of negative, positive, depressive and extrapyramidal symptoms, the premorbid adjustment scale and assessment of demographic and clinical characteristics including duration of untreated psychosis (DUP). Alogia/flat affect and avolition/anhedonia were strongly influenced by parkinsonian and depressive symptoms, respectively. A substantial proportion (26.8%) of patients showed at a least moderate level of negative symptoms not confounded by depression and Parkinsonism. DUP was related only to avolition/anhedonia while flat affect/alogia was related to male gender, diagnosis of schizophrenia, age of onset and the length of the prodrome. Negative symptoms that are independent of the influence of positive symptoms, depression and extra pyramidal symptoms (EPS) are present in a substantial proportion of first episode psychosis patients and delay in seeking treatment is associated mainly with avolition and anhedonia.

Anorexia nervosa (AN) is a psychiatric disorder with high mortality. A retrospective register study of 609 males who received hospitalized care for AN in Sweden between 1973 and 2010 was performed. The standardized mortality ratios (SMRs) and Cox regression-derived hazard ratios (HRs) were calculated as measures of mortality. The incidence rate ratios (IRRs) were calculated to compare the mortality rates in patients with AN and controls both with and without psychiatric diagnoses. The SMR for all causes of death was 4.1 [95% confidence interval (CI) 3.1-5.3]. For those patients with psychiatric co-morbidities, the SMR for all causes of death was 9.1 (95% CI 6.6-12.2), and for those without psychiatric co-morbidity, the SMR was 1.6 (95% CI 0.9-2.7). For the group of patients with alcohol use disorder, the SMR for natural causes of death was 11.5 (95% CI 5.0-22.7), and that for unnatural causes was 35.5 (95% CI 17.7-63.5). The HRs confirmed the increased mortality for AN patients with psychiatric co-morbidities, even after adjusting for confounders. The IRRs revealed no significant difference in mortality patterns between the AN patients with psychiatric co-morbidity and the controls with psychiatric diagnoses, with the exceptions of alcohol use disorder and neurotic, stress-related and somatoform disorders, which seemed to confer a negative synergistic effect on mortality. Mortality in male AN patients was significantly elevated compared with the general population among only the patients with psychiatric co-morbidities. Specifically, the presence of alcohol and other substance use disorders was associated with more profound excess mortality.

Recurrent persistent hypophosphatemia in a male-to-female transgender patient with anorexia nervosa: Case report.

Refeeding hypophosphatemia remains a serious and common complication during the early phases of nutritional rehabilitation and weight restoration for patients with anorexia nervosa. Typically, the risk of refeeding hypophosphatemia diminishes after the first 1-2 weeks of the refeeding process and thus, frequent monitoring serum phosphorus levels becomes less important as refeeding proceeds. Herein, we describe a case of persistent recurrent hypophosphatemia in a male-to-female transgender patient with severe anorexia nervosa. As transgender patients become increasingly seen in the realm of eating disorders, it is worth noting this phenomenon to mitigate adverse events. © 2017 Wiley Periodicals, Inc.

Sperm depletion in males can occur when polygynous species are intensively exploited under a male-biased management strategy. In fisheries involving crabs species, the effects of this type of management on the reproductive potential is far from being understood. This study tests whether male-biased management of the principal Chilean crab fishery is able to affect the potential capacity of Metacarcinus edwardsii males to transfer sperm to females. Five localities in southern Chile, recording contrasting crab fishery landing, were selected to assess the potential of sperm depletion triggered by fishery. Seasonally, male crabs from each locality were obtained. Dry weight and histological condition of vasa deferentia and the Vaso-Somatic Index (VSI) were determined in order to use them as proxies for sperm depletion and male reproductive condition. A manipulative experiment was performed in the laboratory to estimate vasa deferentia weight and VSI from just-mated males in order to obtain a reference point for the potential effects of the fishery on sperm reserves. Sperm storage capacity is significantly affected by fisheries; during the mating season vasa deferentia from localities with low fishery intensity were heavier than those from high intensity fisheries, and these differences were even more evident in large males. Histological section showed that this disparity in vasa deferentia weight was explained principally by differences in the quantity of spermatophores rather than other seminal material. VSI was always higher in males from localities with low fishery intensity. Males from localities with high fishery intensity showed little capacity to recover sperm reserves and the VSI of these males remained below the values of the just-mated males. Detriment in the capacity of males to transfer sperm is the first step to sperm limitation in an exploited population, thus detection of sperm depletion can be an alert to introduce changes in the current management of

Prior studies have shown deficits in social cognition and emotion perception in first-episode psychosis (FEP) and multi-episode schizophrenia (MES) patients. These studies compared patients at different stages of the illness with only a single control group which differed in age from at least one clinical group. The present study provides new evidence of a differential pattern of deficit in facial affect recognition in FEP and MES patients using a double age-matched control design. Compared to their controls, FEP patients only showed impaired recognition of fearful faces (p=.007). In contrast to this, the MES patients showed a more generalized deficit compared to their age-matched controls, with impaired recognition of angry, sad and fearful faces (ps<.01) and an increased misattribution of emotional meaning to neutral faces. PANSS scores of FEP patients on Depressed factor correlated positively with the accuracy to recognize fearful expressions (r=.473). For the MES group fear recognition correlated positively with negative PANSS factor (r=.498) and recognition of sad and neutral expressions was inversely correlated with disorganized PANSS factor (r=-.461 and r=-.541, respectively). These results provide evidence that a generalized impairment of affect recognition is observed in advanced-stage patients and is not characteristic of the early stages of schizophrenia. Moreover, the finding that anomalous attribution of emotional meaning to neutral faces is observed only in MES patients suggests that an increased attribution of salience to social stimuli is a characteristic of social cognition in advanced stages of the disorder.

2015-06-01

Central venous catheterization (CVC)-related venous thrombosis is a common but serious clinical complication, thus prevention and treatment on this problem should be extensively investigated. In this research, we aimed to investigate the incidence rate of CVC-related venous thrombosis in senile patients and give a further discussion on the related risk factors and predictors. A total of 324 hospitalized senile male patients subjected to CVC were selected. Retrospective investigation and analysis were conducted on age, underlying diseases, clinical medications, catheterization position and side, catheter retention time, and incidence of CVC-related venous thrombosis complications. Basic laboratory test results during catheterization and thrombogenesis were also collected and analyzed. Among the 324 patients, 20 cases (6.17%) of CVC-related venous thrombosis were diagnoseds. The incidence rate of CVC-related venous thrombosis in subclavian vein catheterization was significantly lower than that in femoral vein catheterization (P<0.01) and that in internal jugular vein catheterization (P<0.05). No statistically significant difference was found between femoral vein catheterization and internal jugular vein catheterization (P<0.05). Previous venous thrombosis history (P<0.01), high lactate dehydrogenase level (P<0.01), low high-density lipoprotein (HDL) level (P<0.05), and low albumin level (P<0.05) were found as risk factors or predictors of CVC-related venous thrombosis in senile male patients. Subclavian vein catheterization was the most appropriate choice among senile patients to decrease the incidence of CVC-related venous thrombosis. Previous venous thrombosis history, high lactate dehydrogenase level, low HDL level, and low albumin level were important risk factors in predicting CVC-related venous thrombosis.

The frequency of human papillomavirus (HPV) infection in the semen of patients with male accessory gland infection (MAGI) was evaluated. One hundred infertile patients with MAGI were classified into group A: patients with an inflammatory MAGI (n = 48) and group B: patients with a microbial form (n = 52). Healthy age-matched fertile men (34.0 ± 4.0 years) made up the control group (n = 20). Amplification of HPV DNA was carried out by HPV-HS Bio nested polymerase chain reaction for the detection of HPV DNA sequences within the L1 ORF. Ten patients in group A (20.8%) and 15 patients in group B (28.8%) had a HPV infection; two controls (10.0%) had HPV infection. Patients with MAGI had a significantly higher frequency of HPV infection compared with controls; patients with a microbial MAGI had significantly higher frequency of HPV infection compared with patients with an inflammatory form (both P < 0.05). Patients with MAGI and HPV had a slight, but significantly lower sperm progressive motility and normal morphology compared with patients with MAGI HPV-negative (P < 0.05). Elevated frequency of HPV infection occurred in patients with MAGI, suggesting that HPV should be investigated in the diagnostic work-up of these patients.

Androgens Enhance Male Urinary Tract Infection Severity in a New Model

Urinary tract infections (UTIs) occur predominantly in females but also affect substantial male patient populations; indeed, morbidity in complicated UTI is higher in males. Because of technical obstacles, preclinical modeling of UTI in male mice has been limited. We devised a minimally invasive surgical bladder inoculation technique that yields reproducible upper and lower UTI in both male and female mice, enabling studies of sex differences in these infections. Acute uropathogenic Escherichia coli (UPEC) cystitis in C57BL/6 and C3H/HeN males recapitulated the intracellular bacterial community pathway previously shown in females. However, surgically infected females of these strains exhibited more robust bladder cytokine responses and more efficient UPEC control than males. Compared with females, C3H/HeN males displayed a striking predilection for chronic cystitis, manifesting as persistent bacteriuria, high-titer bladder bacterial burdens, and chronic inflammation. Furthermore, males developed more severe pyelonephritis and 100% penetrant renal abscess (a complication that is rare in female mice). These phenotypes were sharply abrogated after castration but restored with exogenous testosterone, suggesting that male susceptibility to UTI is strongly influenced by androgen exposure. These data substantiate the long-standing presumption that anatomic differences in urogenital anatomy confer protection from UTI in males; however, as clinically observed, male sex associated with more severe UTI once these traditional anatomic barriers were bypassed. This study introduces a highly tractable preclinical model for interrogating sex differences in UTI susceptibility and pathogenesis, and illuminates an interplay between host sex and UTI that is more complex than previously appreciated.

Suicide is a major cause of death in schizophrenia. Identifying factors which increase the risk of suicide among schizophrenia patients might help focus prevention efforts. This study examined risk of suicide in male schizophrenia patients using population-based data, examining the timing of suicide in relation to the last hospital discharge, and the effect of premorbid IQ on risk of suicide. Data on 930,000 male adolescents from the Israeli military draft board were linked with data from the Israeli Psychiatric Hospitalization Case Registry and vital statistics from the Israeli Ministry of Health. The relationship between premorbid IQ and risk for suicide was examined among 2881 males hospitalized with schizophrenia and compared to a control group of 566,726 males from the same cohort, who were not hospitalized for a psychiatric disorder, using survival analysis methods. Over a mean follow-up period of 9.9 years (SD=5.8, range: 0-22 years), 77/3806 males with schizophrenia died by suicide (a suicide rate of 204.4 per 100,000 person-years). Approximately 48% of the suicides occurred within a year of discharge from the last hospital admission for schizophrenia. Risk of suicide was higher in male schizophrenia patients with high premorbid IQ (HR=4.45, 95% CI=1.37-14.43) compared to those with normal premorbid IQ. These data indicate that male schizophrenia patients with high premorbid IQ are at particularly high risk of suicide, and the time of peak risk is during the first year after the last hospitalization discharge.

Wolfram syndrome (WFS) is a neurodegenerative genetic condition characterized by juvenile-onset of diabetes mellitus and optic atrophy. We studied clinical features and the molecular basis of severe WFS (neurodegenerative complications) in two consanguineous families from Iran. A clinical and molecular genetic investigation was performed in the affected and healthy members of two families. The clinical diagnosis of WFS was confirmed by the existence of diabetes mellitus and optic atrophy in the affected patients, who in addition had severe neurodegenerative complications. Sequencing of WFS1 was undertaken in one affected member from each family. Targeted mutations were tested in all members of relevant families. Patients had most of the reported features of WFS. Two affected males in the first family had fathered unaffected children. We identified two homozygous mutations previously reported with apparently milder phenotypes: family 1: c.631G>A (p.Asp211Asn) in exon 5, and family 2: c.1456C>T (p.Gln486*) in exon 8. Heterozygous carriers were unaffected. This is the first report of male Wolfram patients who have successfully fathered children. Surprisingly, they also had almost all the complications associated with WFS. Our report has implications for genetic counseling and family planning advice for other affected families. PMID:22781099

Male Reproductive Cancers and Infertility: A Mutual Relationship

Reproductive dysfunction and malignancies related to the male gender represent a serious health concern, whose incidence has significantly risen over the past years. Prior to treatment, testicular or prostate cancer patients often display poor semen characteristics similar to subfertile or infertile patients. This fact is underscored by cases where the malignancy is often diagnosed in males who undergo a general fertility screening. This review aims to examine the associations between male infertility and reproductive cancers focusing on common etiologies and biological mechanisms underlining these pathologies. Furthermore, we discuss compelling epidemiological data hypothesizing that male reproductive failure may act as a precursor of future andrological malignancies, including testicular or prostate cancer, thus providing a stimulus for a more specific research in male reproductive health and emphasizing the importance of this relation for physicians taking care of male patients with a reproductive disease.

Perceived health in lung cancer patients: the role of positive and negative affect.

Hirsch, Jameson K; Floyd, Andrea R; Duberstein, Paul R

2012-03-01

To examine the association of affective experience and health-related quality of life in lung cancer patients, we hypothesized that negative affect would be positively, and positive affect would be negatively, associated with perceived health. A sample of 133 English-speaking lung cancer patients (33% female; mean age = 63.68 years old, SD = 9.37) completed a battery of self-report surveys. Results of our secondary analysis indicate that trait negative affect was significantly associated with poor physical and social functioning, greater role limitations due to emotional problems, greater bodily pain, and poor general health. Positive affect was significantly associated with adaptive social functioning, fewer emotion-based role limitations, and less severe bodily pain. In a full model, positive affect was significantly associated with greater levels of social functioning and general health, over and above the effects of negative affect. Reduction of negative affect is an important therapeutic goal, but the ability to maintain positive affect may result in greater perceived health. Indeed, engagement in behaviors that result in greater state positive affect may, over time, result in dispositional changes and enhancement of quality of life.

Postnatal nutrition influences male attractiveness and promotes plasticity in male mating preferences

Noguera, José C.; Metcalfe, Neil B.; Monaghan, Pat

2017-12-01

Poor early-life nutrition could reduce adult reproductive success by negatively affecting traits linked to sexual attractiveness such as song complexity. If so, this might favor strategic mate choice, allowing males with less complex songs to tailor their mating tactics to maximize the reproductive benefits. However, this possibility has been ignored in theoretical and empirical studies. By manipulating the micronutrient content of the diet (e.g., low or high) during the postnatal period of male zebra finches, we show for the first time (1) that males reared on a poor (low) micronutrient diet had less complex songs as adults; (2) that these males, in contrast to the high micronutrient diet group, were more selective in their mating strategies, discriminating against those females most likely to reduce their clutch size when paired with males having less complex songs; and (3) that by following different mating strategies, males reared on the contrasting diets obtained similar reproductive benefits. These results suggest that early-life dietary conditions can induce multiple and long-lasting effects on male and female reproductive traits. Moreover, the results seem to reflect a previously unreported case of adaptive plasticity in mate choice in response to a nutritionally mediated reduction in sexual attractiveness.

How female and male physicians' communication is perceived differently.

Mast, Marianne Schmid; Kadji, Keou Kambiwa

2018-06-07

This paper is based on a 2017 Baltimore International Conference on Communication in Healthcare (ICCH) plenary presentation by the first author and addresses how female and male physicians' communication is perceived and evaluated differently. Female physicians use patient-centered communication which is the interaction style clearly preferred by patients. Logically, patients should be much more satisfied with female than male physicians. However, research shows that this is not the case. This article provides an overview on how female and male physician communication is evaluated and perceived differently by patients and discusses whether and how gender stereotypes can explain these differences in perception and evaluation. Male physicians obtain good patient outcomes when verbally expressing patient-centeredness while female physicians have patients who report better outcomes when they adapt their nonverbal communication to the different needs of their patients. The analysis reveals that existing empirical findings cannot simply be explained by the adherence or not to gender stereotypes. Female physicians do not always get credit for showing gender role congruent behavior. All in all, female and male physicians do not obtain credit for the same behaviors. Physician communication training might put different accents for female and male physicians. Copyright © 2018 Elsevier B.V. All rights reserved.

Will male advertisement be a reliable indicator of paternal care, if offspring survival depends on male care?

Kelly, Natasha B.; Alonzo, Suzanne H.

2009-01-01

Existing theory predicts that male signalling can be an unreliable indicator of paternal care, but assumes that males with high levels of mating success can have high current reproductive success, without providing any parental care. As a result, this theory does not hold for the many species where offspring survival depends on male parental care. We modelled male allocation of resources between advertisement and care for species with male care where males vary in quality, and the effect of care and advertisement on male fitness is multiplicative rather than additive. Our model predicts that males will allocate proportionally more of their resources to whichever trait (advertisement or paternal care) is more fitness limiting. In contrast to previous theory, we find that male advertisement is always a reliable indicator of paternal care and male phenotypic quality (e.g. males with higher levels of advertisement never allocate less to care than males with lower levels of advertisement). Our model shows that the predicted pattern of male allocation and the reliability of male signalling depend very strongly on whether paternal care is assumed to be necessary for offspring survival and how male care affects offspring survival and male fitness.

Application of psychological interventions is essential in classic treatments for patient with cardiac diseases. The present study compared cognitive emotion regulation strategies, positive affect, and negative affect for cardiac patients with healthy subjects. This study was a case-control study. Fifty subjects were selected using convenient sampling method from cardiac (coronary artery disease) patients presenting in Imam Ali medical center of Kermanshah, Iran in the spring 2013. Fifty subjects accompanied the patients to the medical center, selected as control group, did not have any history of cardiac diseases. For collecting data, the cognitive emotion regulation questionnaire and positive and negative affect scales were used. For data analysis, multivariate analysis of variance (MANOVA) was applied using the SPSS statistical software (ver. 19.0). In all cognitive emotion regulation strategies, there was a significant difference between the two groups. A significant difference was also detected regarding positive affect between the two groups, but no significant difference was found regarding negative affect. We found as a result that, having poor emotion regulation strategies is a risk factor for developing heart diseases. PMID:26234976

Nicotine dependence has been suggested to be related to reinforcement sensitivity, which encompasses behavioral predispositions either to avoid aversive (behavioral inhibition) or to approach appetitive (behavioral activation) stimuli. Reinforcement sensitivity may shape motives for nicotine use and offer potential targets for personalized smoking cessation therapy. However, little is known regarding how reinforcement sensitivity is related to motivational processes implicated in the maintenance of smoking. Additionally, women and men differ in reinforcement sensitivity, and such difference may cause distinct relationships between reinforcement sensitivity and motivational processes for female and male smokers. In this study, the authors characterized reinforcement sensitivity in relation to affect, smoking-related reinforcement motives, and affective responses, using self-report and psychophysiological measures, in over 200 smokers before treating them. The Behavioral Inhibition/Activation Scales (BIS/BAS; Carver & White, 1994) was used to measure reinforcement sensitivity. In female and male smokers, BIS was similarly associated with negative affect and negative reinforcement of smoking. However, positive affect was positively associated with BAS Drive scores in male smokers, and this association was reversed in female smokers. BIS was positively associated with corrugator electromyographic reactivity toward negative stimuli and left frontal electroencephalogram alpha asymmetry. Female and male smokers showed similar relationships for these physiological measures. These findings suggest that reinforcement sensitivity underpins important motivational processes (e.g., affect), and gender is a moderating factor for these relationships. Future personalized smoking intervention, particularly among more dependent treatment-seeking smokers, may experiment to target individual differences in reinforcement sensitivity.

Upper aerodigestive tract symptoms are common in patients with obstructive sleep apnea (OSA). It remains unclear whether continuous positive airway pressure (CPAP) improves or worsens these otolaryngology symptoms. As therapy-related side effects limit CPAP adherence, this study aimed to determine if CPAP negatively affects voice, sinonasal, and reflux symptoms of the upper airway. Case series with planned data collection was performed at an academic otolaryngology sleep center. Newly diagnosed patients with OSA were evaluated before and 6 months after initiating CPAP therapy. Data collected included CPAP data download, Reflux Symptom Index (RSI), Epworth Sleepiness Scale (ESS), Voice Handicap Index 10 (VHI-10), Sino-Nasal Questionnaire (SNQ), and oral dryness visual analog scale (VAS). For the 11 CPAP-adherent participants, the RSI significantly improved with CPAP (mean RSI, 22.0-9.5; P = .002); however, the VAS, VHI-10, and SNQ did not change after 6 months of CPAP therapy. In a small sample size, patient-reported voice outcomes (VHI-10) and other upper aerodigestive tract symptoms did not worsen with CPAP; rather, CPAP therapy was associated with a reduction in reflux symptoms.

The goal of this study was to perform 5-alpha-reductase type 2 gene (SRD5A2) analysis in a male pseudohermaphrodite (MPH) patient with normal testosterone (T) production and normal androgen receptor (AR) gene coding sequences. A patient of Chinese origin with ambiguous genitalia at 14 months, a 46,XY karyotype, and normal T secretion under human chorionic gonadotropin (hCG) stimulation underwent a gonadectomy at 20 months. Exons 1-8 of the AR gene and exons 1-5 of the SRD5A2 gene were sequenced from peripheral blood DNA. AR gene coding sequences were normal. SRD5A2 gene analysis revealed 2 consecutive mutations in exon 4, each located in a different allele: 1) a T nucleotide deletion, which predicts a frameshift mutation from codon 219, and 2) a missense mutation at codon 227, where the substitution of guanine (CGA) by adenine (CAA) predicts a glutamine replacement of arginine (R227Q). Testes located in the inguinal canal showed a normal morphology for age. The patient was a compound heterozygote for SRD5A2 mutations, carrying 2 mutations in exon 4. The patient showed an R227Q mutation that has been described in an Asian population and MPH patients, along with a novel frameshift mutation, Tdel219. Testis morphology showed that, during early infancy, the 5-alpha-reductase enzyme deficiency may not have affected interstitial or tubular development.
