Quality of medical research reports should be evaluated before they are applied to clinical practice. Since 1990s, several guidelines on research reports were suggested. Most recently published Consolidated Standards of Reporting Trials statement 2010 consists of 25 checklists and flow diagram for reporting an randomized controlled trial. Strengthening the reporting of observational studies in epidemiology statement is a checklist of items that should be addressed in articles reporting on the observational studies in epidemiology. TREND statement for the reporting of nonrandomized designs consists of 22 checklists. The Quality of Reporting of Meta-analyses checklist proposes to provide checklist and flow diagram for reporting of meta-analyses. The Meta-analysis of Observational Studies in Epidemiology statement proposes a checklist for compensating the study errors about observational studies in epidemiology. After development of reporting guidelines, improvements in the quality of reports are continuously reported, so using guidelines in the medical research will be expected to be more generalized.

On the horizon there is a new class of psychoactive medications which work by inhibiting the neuronal reuptake of serotonin, norepinephrine, and dopamine. There are multiple potential indications for these drugs. Research suggests that they may have a role in treating depressive disorders, and it is plausible they may have potential efficacy in obesity, addiction, and pain syndromes. The current review describes some of the molecules in development presently and explores the research relevant to possible clinical uses for this class of medications.

Pregabalin is a newly developed synthetic gamma-aminobutyric acid (GABA) that is approved for the treatment of fibromyalgia and several neuropathy. It has been proven to show analgesic, anxiolytic, anticonvulsant and sleep enhancement effects, which could be applicable in the treatment of a variety of psychiatric disorders. There have been consistent reports that unexplained somatic symptoms (i.e., pain) may be a part of psychiatric disorders such as major depressive disorder (MDD) and anxiety disorders. Previous researches have also suggested the possible therapeutic potential of anticonvulsants as augmentation therapy or monotherapy in the treatment of mood disorders and anxiety disorders. Hence this short perspective tries to prompt and facilitate a shifting of researchers' attention to potential neuropsychotropic drug role of pregabalin to treat a wide range of neuropsychiatric disorders.

We tried to review and update clinical and preclinical studies evaluating vilazodone's role as an antidepressant for patients with major depressive disorder (MDD). In terms of its mechanism of actions, we sought to elaborate them mainly through preclinical animal studies. A data search was conducted in November 1, 2013, using the key terms "vilazodone" or "Viibryd," in PubMed and Medline databases. All published and unpublished studies are included and citations from publications were also reviewed for additional references. Five unpublished, phase-II and two pivotal published phase-III clinical trials with nearly identical design (8-week, double-blind, randomized, and placebo-controlled) investigated efficacy of vilazodone, were found for the treatment of patients with MDD. Two post-hoc studies and one long-term open study were also included. Data were thoroughly reviewed to incorporate the pharmacology, action mechanism, efficacy and safety for the vilazodone in the treatment of major depressive disorder. Vilazodone is an antidepressant with novel mechanism of action because its chemical structure is unrelated to conventional antidepressant, and it has a selective serotonin (5-HT) reuptake inhibitor and 5-HT1A receptor partial agonist profile. Vilazodone is an effective and safe treatment option with its novel action mechanisms for patients with depression. Its putative benefits compared with other antidepressants must be thoroughly studied in adequately-powered and well-designed future clinical trials.

OBJECTIVE: The present study aimed to observe potential benefit of aripiprazole augmentation in the treatment of major depressive disorder with mixed specifier (MDDM) in naturalistic treatment setting. METHODS: Data were collected from MDDM patients using a retrospective chart review for 8 weeks (week –8 and week 0) in routine practice. All patients were on current antidepressants upon starting of aripiprazole. Patients were treated without restriction of doses of aripiprazole. The primary endpoint was the mean change of Montgomery–Åsberg Depression Rating Scale (MADRS) total scores along with various secondary endpoint measures. RESULTS: In total 38 patients were analyzed. The changes of MADRS, Clinical Global Impression (CGI)-severity, Young Mania Rating Scale, Sheehan Disability Scale, and CGI-clinical benefit total scores from baseline to the endpoint were −7.1, −0.8, −4.9, −4.1, and −3.6, respectively (all p < 0.0001). At the endpoint, the responder and remitter rates by MADRS score criteria were approximately 32% and 21%, respectively. CONCLUSION: The present findings have clearly shown the effectiveness and tolerability of aripiprazole augmentation for MDDM patients in routine practice. The present study warrants subsequent, adequately-powered, well-controlled studies for generalizability near future.

The aim of the present work is to investigate the existence of epistatic interactions possibly influencing psychotropic agents' response between rs6740584 within Cyclic adenosine monophosphate Response Element Binding (CREB) and rs12775799 within cAMP response element-modulator (CREM) variants in bipolar disorder (BD) and major depressive disorder (MDD). All BD and MDD patients were administered with the Young Mania Rating Scale (YMRS) and Hamilton Depression Rating Scale (HAMD) at baseline and at endpoint, respectively. A multiple regression model was employed to investigate the existence of possible epistatic interactions between the two variants and diverse clinical factors including drug response in affective disorders. No significant epistatic interaction was observed between rs6740584 within CREB and rs12775799 within CREM on both symptom improvement and other clinical factors in affective disorders. Our preliminary results suggest that no epistatic interaction between rs6740584 within CREB and rs12775799 within CREM should exist on clinical improvement and clinical factors in affective disorders.

The mainstay of schizophrenia treatment is pharmacological therapy using various antipsychotics including first- and second-generation antipsychotics which have different pharmacokinetic and pharmacodynamic property leading to differential presentation of adverse events (AEs) and treatment effects such as negative symptoms, cognitive symptoms and cormorbid symptoms. Major treatment guidelines suggest the use of antipsychotic monotherapy (APM) as a gold standard in the treatment of schizophrenia. However, the effects of APM is inadequate and less potent to achieve symptom remission as well as functional recovery in real practice which has been consistently reported in numerous controlled clinical trials, large practical trials, independent small studies and systematic reviews till today. Therefore antipsychotic polypharmacy (APP) regardless of the class of antipsychotics has been also commonly utilized for many reasons in real world practice. However, APP has also crucial pitfalls including increase of total psychotics including antipsychotics, high-doses of antipsychotics used, poor compliance, drug-drug interaction and risks for developing AEs, all of which are paradoxically related to poor clinical outcomes, whereas APP has also substantial advantages in reduction of re-hospitalization, severe psychopathology and targeted control of concurrent symptoms. Given currently limited therapeutic options, it is also important to properly utilize APP in order to maximize its clinical utility and minimize its risk for better treatment outcomes for patients with schizophrenia, based on risk/benefit with full understanding of pharmacological and clinical issues on APP. The present paper intends to address intriguing and important issues in the use of APP in real world practice.

Antipsychotic monotherapy (APM) is considered best-acceptable treatment option regardless of antipsychotic class and formulation types for treating schizophrenia. However, antipsychotic polypharmacy (APP) has been also widely utilized in routine clinical practice. Despite APP has some clinical benefits it has also numerous pitfalls in relation with increased total number and doses of APs leading to adverse events as well as decrease of treatment adherence and persistence resulting in poor clinical outcomes. Recent introduction of long-acting injectable antipsychotics (LAIs) to the market has offered a chance for better medication adherence/persistence and also provided a simplification of treatment regime leading to more stabilized treatment for schizophrenia patients. When we cannot stay away from APP in the treatment of schizophrenia, clinicians need to find more proper APP regimens and thereby utilization of APP in efficient way should be a practical strategy to benefit schizophrenia patient in a real world treatment setting. With this regard, LAIs can be one of available APP regimen for treatment of schizophrenia in routine practice since their clinical utility and pharmacokinetic stability over oral APs have been well-elaborated today. However, when we have to commence LAIs as a part of APP with oral APs or other LAIs, every effort should be made before doing so whether or not validated and available treatment options or other clinical factors were not done or evaluated yet. Any treatment guidelines do not support APP regardless of the formulation of APP regimen or address two or more LAIs for treatment of schizophrenia till today.

Objective: In a number of controlled clinical trials and naturalistic studies, aripiprazole once monthly (AOM) has been found to be effective and safe as acute and maintenance treatment options for schizophrenia. However, such clinical data have been presented in selected patient population (i.e., antipsychotic monotherapy, etc.), in particular, clinical information on switching to AOM from antipsychotic polypharmacy and/or other long acting injectable antipsychotics (LAIs) has been scarce till today. Methods: The study period was from the first switching day to AOM up to 12 months in patients with antipsychotic polypharmacy (APpoly)/LAIs (baseline, month 3, month 6, and month 12). Available demographics and clinical information were retrieved from electronic medical records (EMRs). Available scores of Global Assessment of Functioning (GAF), Clinical Global Impression-Clinical Benefit (CGI-CB), CGI-severity, Visual Analog Scale on Satisfaction-Patient/Health Professional (VAS-P/HP), and the Positive and Negative Syndrome Scale-Insigh (PANSS-I) scores were also taken from EMR. Proportional change of functional impairment before and after AOM was also captured. Results: Data of 18 patients were available. Most commonly used combined APs before AOM were aripiprazole, blonanserin, quetiapine, and risperidone. At least 2 APs (n = 2.4) were combined before AOM. Scores of GAF (10.7% increase), CGI-CB (46.2% decrease), VAS-P (47.8% increase), VAS-HP (40.8% increase), and PANSS-I (27.9% increase) (all p = 0.001) were significantly improved from baseline to month 12, respectively. Approximately 59% of patients improved individual functioning with different level (i.e., employment, back to school, etc.) after AOM treatment at month 12. Conclusion The present study have clearly shown the clinical benefit and utility of switching to AOM for treatment of patients with APpoly/LAIs in routine practice. Subsequent, adequately-powered, well-controlled clinical trials may be necessary to confirm our findings in near future.
