Hane Htut Maung
It is often claimed in parts of the psychiatric literature that neuroscientific research into the biological basis of mental disorder undermines dualism in the philosophy of mind. This paper shows that such a claim does not apply to all forms of dualism. Focusing on Kenneth Kendler's discussion of the mind-body problem in biological psychiatry, I argue that such criticism of dualism often conflates the psychological and phenomenal concepts of the mental. Moreover, it fails to acknowledge that there are different varieties of dualism, and so overlooks the important metaphysical insights of contemporary dualist philosophers...

Background: Previous studies have shown that the hypothalamus-pituitary-adrenal-axis (HPA-axis) is closely involved in the development of affective disorders. Given that early life events are also linked to dysregulation of the same system, there might be an association between childhood adversities and suicidal behavior in affective disorders, moderated by HPA-axis genes. We aimed to investigate a potential association between childhood trauma and previous suicide attempts in affective disorder patients, moderated by variants of the corticotropin-releasing hormone receptor 1 (CRHR1) gene...

Transgender is a complex state of bio-psycho-social dimension of human sexuality. It encompasses cognitive-emotional-behavior component that makes the person unique in his or her sexual expression. Transgender tend to use cross sex hormone in order to eradicate their secondary sexual characteristics and to facilitate the shift to their experienced gender. The common masculinising sex hormone use, i.e. Female to Male Treatment Options (FMTO) is testosterone and for feminising hormone i.e. Male to Female Treatment Options (MFTO) is a combination of estrogen with anti-androgen, respectively...

Angelica Ronald, Oliver Pain
We present a systematic review of genome-wide research on psychotic experience and negative symptom traits (PENS) in the community. We integrate these new findings, most of which have emerged over the last four years, with more established behaviour genetic and epidemiological research. The review includes the first genome-wide association studies of PENS, including a recent meta-analysis, and the first SNP heritability estimates. Sample sizes of < 10,000 participants mean that no genome-wide significant variants have yet been replicated...

João Gama Marques, Filipe Arantes-Gonçalves
Some authors suggest a relation between Unconjugated Bilirubin (UCB) plasma high levels and schizophrenia, as schizophrenia patients have been showing higher UCB levels when compared with other psychiatric patients and general population. These higher UCB levels have been already correlated with acute psychotic states, positive symptoms, and poor outcome in patients with schizophrenia. Schizophrenia and schizoaffective disorders share common symptoms but there aren't yet accepted biomarkers for their distinction...

Glen O Gabbard
Psychodynamic psychiatry is a way of thinking that places the person at the heart of diagnostic understanding and treatment. This emphasis on unique characteristics of an individual is at odds with much of contemporary psychiatric thought, which is geared to identifying a set of criteria designed to identify discrete diagnostic categories with biological underpinnings. This article addresses component parts of the person that are linked to psychodynamic constructs and lie at the heart of diagnostic understanding and treatment in psychodynamic psychiatry...

Histone deacetylases (HDACs), which regulate transcription and specific functions such as tumor suppression by p53, are frequently altered in tumors and have a contentious role in carcinogenesis. HDAC inhibitors, which have a long history of use in psychiatry and neurology, have recently been tested as possible treatments for tumors. Belinostat received regulatory approval in the USA on July 3, 2014, for use against peripheral T-cell lymphoma. However, the unavailability of information on belinostat genotoxicity in normal cells and the molecular mechanisms involved in the genetic instability after exposure to belinostat encouraged us to conduct this study...

Walter L Miller
The hypothalamic-pituitary-adrenal (HPA) axis is central to homeostasis, stress responses, energy metabolism, and neuropsychiatric function. The history of this complex system involves discovery of the relevant glands (adrenal, pituitary, hypothalamus), hormones (cortisol, corticotropin, corticotropin-releasing hormone), and the receptors for these hormones. The adrenal and pituitary were identified by classical anatomists, but most of this history has taken place rather recently, and has involved complex chemistry, biochemistry, genetics, and clinical investigation...

Importance: There is urgent need to improve the limited prognostic accuracy of clinical instruments to predict psychosis onset in individuals at clinical high risk (CHR) for psychosis. As yet, no reliable biological marker has been established to delineate CHR individuals who will develop psychosis from those who will not. Objectives: To investigate abnormalities in a graph-based gyrification connectome in the early stages of psychosis and to test the accuracy of this systems-based approach to predict a transition to psychosis among CHR individuals...

The objectives are to review the role of pharmacogenomics in drug metabolism of medications typically used in patients with irritable bowel syndrome (IBS) focusing predominantly on cytochrome P450 metabolism. Other aims are to provide examples of genetic variation of receptors or intermediary pathways that are targets for IBS drugs and to critically appraise the situations where precision medicine is impacting health in IBS. Pharmacogenomics impacts both pharmacokinetics and pharmacodynamics. Although large clinical trials have not incorporated testing for genetic variations that could impact the efficacy of medications in IBS, there are therapeutic advantages to inclusion of pharmacogenomics testing for individual patients, as has been demonstrated particularly in the treatment with central neuromodulators in psychiatry practice...

Mood disorders comprise major depressive disorder (MDD), bipolar disorder (BD) and the milder forms of these two disorders. Reccurring MDD is also known as unipolar disorder. The distinction between unipolar and bipolar disorders was first suggested in 1957 by Leonard and was made official after support by several studies in 1980. Indeed, in 150 AD, Aretaeus of Cappadocia wrote "It seems to me that melancholia is the beginning and a part of mania". Additionally, Kraepelin, who proposed the first medical disease model in psychiatry a century ago, considered recurrent unipolar depression cases under the category of bipolar disorder and conceptualized spectrum disorders...

Progress in PTSD pharmacotherapy has lagged far behind that of other major mental illnesses. Unfortunately, due to the enormous costs and lengthy process involved in bringing drugs to market, delivering new treatments to patients with PTSD in the near future will remain a challenge. However, by capitalizing on recent advances in the pharmacogenetics of antidepressants, precision psychiatry approaches can be leveraged to optimize the delivery of currently-available medications in a fraction of the time and cost required to develop novel therapeutics...

Yukiko Y Lema, Nao J Gamo, Kun Yang, Koko Ishizuka
To further improve clinical activities in psychiatry by early diagnosis and early intervention with novel mechanism-guided treatments, there is a great need for biomarkers that reflect "trait" and "state" in major mental disorders. Stable trait biomarkers would allow early diagnosis, prognosis, and hopefully early intervention in these disorders, while dynamic state markers that reflect symptomatic changes would help to develop treatments that target these molecular mechanisms. However, in the search for such biomarkers, and eventually translating them to the clinic and industry, challenges currently exist at multiple levels, from basic scientific understanding, patient sample collection, and sample and data management, to bridging the gap between basic and clinical research and industry...

BACKGROUND: Alcohol dependence (AD), characterized by profound disruptions in specific circuits of the brain is influenced by both environmental, which play a significant role in developing addiction and genetic factors, which make some individuals more susceptible to disruptions. Various polymorphisms in the neurotransmitter genes are reported to increase the risk of developing dependence. The present study aimed to identify association of serotonin and GABA polymorphisms with AD in Indian subjects...

Bipolar disorder (BD) is a heritable mood disorder characterized by episodes of mania and depression. Although genomewide association studies (GWAS) have successfully identified genetic loci contributing to BD risk, sample size has become a rate-limiting obstacle to genetic discovery. Electronic health records (EHRs) represent a vast but relatively untapped resource for high-throughput phenotyping. As part of the International Cohort Collection for Bipolar Disorder (ICCBD), we previously validated automated EHR-based phenotyping algorithms for BD against in-person diagnostic interviews (Castro et al...
