Purpose: This study investigated disparities in dual diagnosis (comorbid substance-use and depressive/anxiety disorders) among US adults by nativity and racial-ethnic origin and socioeconomic, cultural, and psychosocial factors that may account for the observed disparities. Design/methodology: The study drew on data from two waves of the National Epidemiological Survey on Alcohol and Related Conditions. Racial-ethnic categories included African, Asian/Pacific Islander, European, Mexican, Puerto Rican, and other Hispanic/Latino...

Catatonia is an independent syndrome that co-occurs with several mental and medical conditions. We performed a systematic literature review in PubMed/Scopus until February 2017 and meta-analyzed studies reporting catatonia prevalence. Across 74 studies (cross-sectional = 32, longitudinal = 26, retrospective = 16) providing data collected from 1935 to 2017 across all continents, mean catatonia prevalence was 9.0% (k = 80, n = 110764; 95% CI = 6.9-11.7, I2 = 98%, publication bias P < .01), decreasing to 7...

Genetic, epidemiological and post mortem studies have described an association between schizophrenia (SCZ) and the immune system. Microglia, the tissue-resident macrophages of the brain, not only play an essential role in inflammatory processes, but also in neurodevelopment and synapse refinement. It has therefore been hypothesized that aberrant functioning of these myeloid immune cells is involved in SCZ pathogenesis. Until now cellular research into the role of myeloid cells in SCZ has been limited to monocytes and functional assays are lacking...

BACKGROUND: Depression is one of the most prevalent psychiatric disorders, and in older persons is associated with high levels of comorbidity and under-treatment. Dysfunction of the hypothalamic-pituitary-adrenal (HPA) stress axis is consistently observed in the older population as well as depressed patients, with the angiotensin converting enzyme (ACE) a key regulator of the stress response. Epigenetic regulation of ACE may play an important role in HPA axis (dys)regulation. OBJECTIVE: To investigate ACE promoter methylation as a biomarker of late-life depression, and its association with genetic variation and cortisol secretion...

Depression, the most frequent psychiatric disorder following ischaemic stroke, negatively affects survivals' functional outcome, response to rehabilitation and quality of life. Approximately, one-third of them are affected by post-stroke depression (PSD), making it a serious social and public health problem and anti-depressant preventive and curative therapies worth investigating. However, a two-way association between depression and stroke has been also established: stroke increases the risk of PSD, but depression is an independent risk factor for stroke...

INTRODUCTION: The symptoms of low testosterone frequently overlap with psychiatric complaints including depression and fatigue. Testosterone repletion has been shown to improve mood symptoms in men with low testosterone, although this finding has not been consistent across all studies. Despite the potential importance of low testosterone for psychiatry, the prevalence of low testosterone in men who present to psychiatric clinics with mental health complaints is unknown. AIM: To provide an overview of the current state of knowledge of the psychiatric complications of male hypogonadism, the challenges of screening for hypogonadism in a psychiatric population, and the potential mental health treatment implications of hypogonadism...

The treatment for penile cancer has been shown to cause harmful psychiatric symptoms as well as have detrimental effects on well-being. In the past several years, alternatives to total or partial penectomy have emerged, such as chemotherapy, radiation, penile sparing, and laser ablation therapies. A more specific breakdown for penile cancer is in order as the therapy has the potential for life changing surgery. We examined the Surveillance, Epidemiology, and End Results (SEER) database (1973-2013), comprising 28% of the United States population...

BACKGROUND: Obsessive-compulsive disorder (OCD) symptoms within the context of a bipolar disorder (BD) have been described since the 19th century. Interestingly, the existence of a relevant overlap between the aforementioned psychiatric syndromes has been confirmed by a number of recent epidemiological and family studies. AIMS: The aim of the present paper is to review the clinical features and the therapeutic implications of the OCD-BD comorbidity. DISCUSSION: In the last two decades, the frequent association between OCD and BD has been earning a growing interest given its relevant nosological and therapeutic implications...

Knowledge about prevalence rates of psychiatric disorders and mental health services use among parents and relatives of persons with autism spectrum disorder (ASD) is limited, particularly when referring to epidemiologic samples. The current study is based on an island-wide probabilistic multistage cluster sample of adult individuals (N = 3062) living in Puerto Rico. Results showed a significantly higher rate of attention deficit hyperactivity disorder and serious mental illness in parents (n = 34) or relatives (n = 34) of ASD individuals, as compared with the Puerto Rico adult population as a whole...

Background: Many recent epidemiological studies have shown that epileptic patients are more likely suffer from depression, anxiety, and irritability. However, the cellular mechanisms of epilepsy-induced psychotic behaviors are not fully elucidated. Neurotrophin receptors have been suggested to be involved in epilepsy and also in psychiatric disorders. Up-regulation of p75NTR expression and activation of p75NTR signalling cascades after the seizure have been shown, but the role of the p75 receptor in epilepsy-induced psychotic behaviors has not been documented so far...

A possible role for Toxoplasma gondii in the etiopathogenesis of schizophrenia is supported by epidemiological studies and animal models of infection. However, recent studies attempting to link Toxoplasma to schizophrenia have yielded mixed results. We performed a nested case-control study measured serological evidence of exposure to Toxoplasma gondii in a cohort of 2052 individuals. Within this cohort, a total of 1481 individuals had a psychiatric disorder and 571 of were controls without a psychiatric disorder...

The neurophysiology underlying temporal perception significantly overlaps with areas of dysfunction identified in schizophrenia. Patients commonly exhibit distorted temporal perception, which likely contributes to functional impairments. Thus, study of temporal perception in animal models of the disease may help to understand both cognitive and neurobiological factors involved in functional impairments in patients. As maternal immune activation (MIA) has been shown to be a significant etiological risk factor in development of schizophrenia and other developmental psychiatric diseases, we tested interval timing in a rat model of MIA that has previously been shown to recapitulate several behavioural and neurophysiological impairments observed in the disease...

OBJECTIVE: Researchers need to be confident about the reliability of epidemiological studies that quantify medication use through self-report. Some evidence suggests that psychiatric medications are systemically under-reported. Modern record linkage enables validation of self-report with national prescribing data as gold standard. Here, we investigated the validity of medication self-report for multiple medication types. STUDY DESIGN AND SETTING: Participants in the Generation Scotland population-based cohort (N=10,244) recruited 2009-11 self-reported regular usage of several commonly prescribed medication classes...

Importance: Positive associations between inflammatory biomarkers and risk of psychiatric disorders, including schizophrenia, have been reported in observational studies. However, conventional observational studies are prone to bias, such as reverse causation and residual confounding, thus limiting our understanding of the effect (if any) of inflammatory biomarkers on schizophrenia risk. Objective: To evaluate whether inflammatory biomarkers have an effect on the risk of developing schizophrenia...

Substance abuse is a health problem with serious psychological and psychiatric dimensions and multiple social and economic consequences. Cancer is a disease that threatens not only life and physical integrity but mental health as well. Oncology patients suffer from mental disorders in high rates, especially from depression and anxiety. The role of substance abuse in the pathogenesis of cancer is studied systematically, since there are research data supporting the mutagenic effects of certain substances. It has been supported that a possible dysregulation of the immune system is linked to the oncogenic processes induced by substances of abuse...

BACKGROUND: Major Depressive Disorder (MDD) and Bipolar Disorder (BPD) are the most severe mood disorders globally. Previous reports indicate high co-occurrence of cannabis use and cannabis use disorders (CUDs) associated with both disorders, yet studies comparing patterns of cannabis use between individuals with MDD and BPD are scarce. METHODS: Data were drawn from Wave 1 (2001-2002) of the National Epidemiologic survey on Alcohol and Related Conditions (NESARC)...
