It is increasingly acknowledged that a sex and gender specificity affects the occurrence, development, and consequence of a plethora of pathologies. Mitochondria are considered as the powerhouse of the cell because they produce the majority of energy-rich phosphate bonds in the form of adenosine tri-phosphate (ATP) but they also participate in many other functions like steroid hormone synthesis, reactive oxygen species (ROS) production, ionic regulation, and cell death. Adequate cellular energy supply and survival depend on mitochondrial life cycle, a process involving mitochondrial biogenesis, dynamics, and quality control via mitophagy...

The environment plays a critical role in shaping development and function of the brain. Stress, especially when experienced early in life, can interfere with these processes. In the context of respiratory control, perinatal stress can therefore alter the ability to achieve the "fine-tuning" necessary for proper detection of chemosensory stimuli and production of an adequate motor (respiratory) command. Depending on the timing, intensity, and duration, the detrimental consequences of perinatal exposure to adverse conditions on the respiratory network become manifest at various life stages and can persist into adulthood...

OBJECTIVE: To examine the 3-year course of multiple co-occurring substance use disorders (SUDs) based on longitudinal survey data from a large, nationally representative sample. METHODS: National estimates of the prevalence of DSM-IV SUDs were derived by analyzing data from structured, face-to-face diagnostic interviews as part of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), which collected data from a large, nationally representative sample of noninstitutionalized US adults at 2 waves (2001-2002 and 2004-2005; N = 34,653)...

Female Sexual Disorders (FSD) include a complex, multidimensional, individual experience that can change as an individual age, suggesting that these problems are caused by multiple factors including psychosocial factors, personal relationships, pathologic changes caused by diseases, and pharmacologic influences. Menopause is an important time for middle aged women and postmenopausal physiological changes could have a significant role in the development of FSD. Few is still known about their correct definition and treatment...

Nearly one-third of individuals in treatment for substance use disorders endorse at-risk levels of compulsive sexual behaviours (CSBs). Untreated sexual compulsivity may facilitate relapse for treatment-seeking men. Previous research and theory suggest that CSBs are maintained by efforts to escape or alter negative affect (e.g., depression and anxiety). However, this hypothesis has not been examined within a sample of men in treatment for substance use disorders. In an effort to better understand CSBs within a population of men with substance use disorders, the present study is the first to examine experiential avoidance as one potential mechanism underlying the relation between men's symptoms of depression and anxiety and their use of CSBs...

The majority of mental disorders have their onset in late adolescence and early adulthood and this coincides with important stages of sexual development. Although sexual dysfunction is highly prevalent among people with mental health disorders, little is known about this topic among youth. This study aimed to evaluate the sexual functioning and subjective experience of sex in young people aged between 15 and 26 years attending a youth mental health service. One hundred and three participants were assessed with the Sexual Health Questionnaire, Sexual Functioning Questionnaire, Brief Psychiatric Rating Scale, Scale for the Assessment of Negative Symptoms and the Medication Adherence Rating Scale...

Depressive symptoms and suicidal behavior are common among patients that suffered a first-episode psychosis. We searched Web of Knowledge(SM) and Pubmed® for English and Portuguese original articles investigating prevalence of depressive symptoms and/or suicidal behavior and associated factors after first-episode psychosis. We included 19 studies from 12 countries, 7 studied depressive symptoms and 12 suicidal behavior. The findings confirm that depressive symptoms and suicidal behavior have high rates in the years after first-episode psychosis...

The aim of this review is to analyze current diagnostic approaches to obesity in adult men, the potential mechanisms linking obesity to infertility, and treatment options aimed at improving reproductive health. Obesity has become a worldwide epidemic with the estimated prevalence increasing from 28.8% to 36.9% between 1980 and 2013. In terms of diagnosis, numerous simple techniques have been developed including body mass index, waist to hip ratio, waist circumference, bioelectrical impedance analysis, ultrasound and skinfold measurements...

PURPOSE: Intimate partner violence (IPV) has been recognised as a major obstacle to the achievement of gender equality and human development. Its adverse physical and mental health consequences have been reported to affect women of all ages and backgrounds. Although Indigenous women seem to experience higher rates of partner abuse than non-Indigenous women, mental health consequences of IPV among this population are not yet clearly established in the literature. This study systematically reviewed the global literature on mental health outcomes and risk factors for mental ill health among Indigenous women who experienced IPV...

PURPOSE OF REVIEW: Lower urinary tract and sexual dysfunction are commonly reported sequelae of neurologic disease and have a significant impact on quality of life. This article presents an up-to-date summary of the clinical presentation, investigations, and treatment options for urogenital dysfunction in patients with neurologic disease. RECENT FINDINGS: The pattern of lower urinary tract dysfunction is influenced by the site of the neurologic lesion. The risk for developing upper urinary tract damage is considerably less in patients with slowly progressive nontraumatic neurologic disorders, as compared to those with spinal cord injury or spina bifida...

Youth runaway behavior and homelessness (RHY) in the U.S. is increasingly common, with prevalence estimated at 1-1.7 million youth. RHY have multiple, overlapping problems often including poor physical and mental health, frequent street victimization, and histories of physical and sexual abuse. Further, current street victimization interacts with childhood abuse to produce complex, unique presentations of traumatic symptoms and related disorders in runaway and homeless youth. This review paper explores (1) the role of childhood trauma in the genesis of runaway and homeless behavior, and (2) how childhood trauma interacts with street victimization to create vulnerability to psychopathology...

Ovotesticular or testicular disorder of sexual development in dogs with female karyotype and lack of SRY (XX DSD) is a common sexual anomaly diagnosed in numerous breeds. The molecular background, however, remains unclear, and epigenetic mechanisms, including DNA methylation, have not been studied. The aim of our study was comparative methylation analysis of CpG islands in promoters of candidate genes for XX DSD: SOX9, SOX3, and WNT4. Methylation studies were performed on DNA extracted from formalin-fixed/paraffin-embedded or frozen gonads from 2 dogs with ovotesticular and 2 dogs with testicular XX DSD as well as control females (n = 4) and males (n = 2)...

The luteinizing hormone receptor (LHCGR) is necessary for fertility and genetic mutations cause defects in reproductive development and function. Activating mutations in LHCGR cause familial male limited precocious puberty (FMPP). We have previously characterized a mouse model (KiLHRD582G) for FMPP that exhibits the same phenotype of precocious puberty, Leydig cell hyperplasia and elevated testosterone as boys with the disorder. We observed that KiLHRD582G male mice became infertile by 6 months of age although sperm count and motility were normal...

Decades of genetic selection have generated 2 different, highly specialized types of chickens in which 1 type, known as the layer-type chicken, expresses high laying performance while the other type, known as the broiler-type chicken, is dedicated to the production of fast-growing birds. Selected lines for the latter type often express disorders in their reproductive performance including early sexual maturation and accelerated, non-reversible seasonal decline of their semen production and mating behavior. The aim of the present study was to characterize some metabolic markers of the Sertoli cell populations...

Most children who experience an acquired demyelinating syndrome of the central nervous system will have a monophasic disease course, with no further clinical or radiological symptoms. A subset will be diagnosed with multiple sclerosis, a life-long disorder. Using linear mixed effects models we examined longitudinal diffusion properties of normal-appearing white matter in 505 serial scans of 132 paediatric participants with acquired demyelinating syndromes followed for a median of 4.4 years, many from first clinical presentation, and 106 scans of 80 healthy paediatric participants...

Cancer is a physical disease and also one of the leading clinical manifestations where psychosocial problems are prevalent. Psychosocial problems that these patients may have in the long run include anxiety, uneasiness, mourning, helplessness, fatigue, impairment of concentration, sleep disorders, mental and cognitive reservation, sexual dysfunction, infertility, psychological distress, and psychiatric disorders. Psychosocial problems have a nature of underpinning the emergence of psychological troubles. The prevalence of psychological disorders in patients with cancer range from 29% to 47%...

Betamethasone is the drug of choice for antenatal treatment, promoting fetal lung maturation and decreasing mortality. Previous studies in rats reported male programming and alteration in sperm parameters and sexual behavior following intrauterine betamethasone exposure. The impact on the female reproductive development is not known. In this study, rat female offspring was assessed for sexual development, morphophysiology of the reproductive tract and fertility after maternal exposure to 0.1 mg kg(-1) of betamethasone or vehicle on gestational days 12, 13, 18 and 19...

Research on disorganization of infant attachment provides evidence that it can be caused not only by violent aggression or very early sexual abuse, but also by covert maltreating behavior, which includes the abdication of the caregiver's responsibility to soothe the infant's distress. This paper argues that both overtly abusive caregivers and merely "abdicating" caregivers may cause disorganization of infant attachment through a simultaneous and conflicting activation of the motivational systems governing attachment and survival defense in the infant...

Many pharmacological and psychological approaches have been found efficacious in patients with generalized anxiety disorder (GAD), but many treatment-seeking patients will not respond and others will relapse despite continuing with interventions that initially had beneficial effects. Other patients will respond but then stop treatment early because of untoward effects such as sexual dysfunction, drowsiness, and weight gain. There is much scope for the development of novel approaches that could have greater overall effectiveness or acceptability than currently available interventions or that have particular effectiveness in specific clinical subgroups...

Eating disorders are highly sexually differentiated disorders that exhibit a female predominance in risk. Most theories focus on psychosocial explanations to the exclusion of biological/genetic influences. The purpose of this descriptive review is to evaluate evidence from animal and human studies in support of gonadal hormone effects on sex differences in binge eating. Although research is in its nascent stages, findings suggest that increased prenatal testosterone exposure in males appears to protect against binge eating...
