Our results show that melatonin is effective in attenuating SGAs' adverse metabolic effects, particularly in bipolar disorder. The clinical findings allow us to propose that SGAs may disturb a centrally mediated metabolic balance that causes adverse metabolic effects and that nightly administration of melatonin helps to restore. Melatonin could become a safe and cost-effective therapeutic option to attenuate or prevent SGA metabolic effects.

BackgroundClassification of Psychiatric Emergency Presentations (PEP) is not sufficiently clear due to their inherent high inter-subjectivity and lack of validated triage instruments. In order to improve current classification of psychiatric emergency presentations (PEP) at Emergency Departments, we implemented and validated the Color-Risk Psychiatric Triage (CRPT), an instrument for classifying PEP risk by sorting one to five color/risk levels and one to thirty-two possible conditions arranged by risk.MethodsUsers who visited the Emergency Department (ED) of a Mexican psychiatric hospital from Dec 1st, 2008 to Dec 1st, 2009 were included. One CRPT was assessed by an ED psychiatrist to each patient upon their arrival to ED. Some patients were randomly assessed simultaneously with an additional CRPT and a Crisis and Triage Rating Scale (CTRS) to test validity and reliability of the CRPT.ResultsA total of 7,631 CRPT assessments were included. The majority of PEP were non-urgent (74.28 %). For the validation phase n = 158 patients were included. CRPT score showed higher concurrent validity than CRPT color/risk. CRPT level/risk and score showed highest concurrent validity within dangerousness domain of CTRS (r = 0.703, p < 0.0001). CRPT and CTRS scores showed similar predictive validity (p < 0.0001). High intraclass correlation coefficient (0.982) and Cohen’s Kappa (0.89) were observed for CRPT score (r = 0.982, p < 0.0001).ConclusionsCRPT appeared to be a useful instrument for PEP classification due to its concurrent validity, predictive validity and reliability. CRPT score showed higher correlations than the CRPT color/risk. The five levels of risk provided by the CRPT appear to represent a simple and specific method for classifying PEP. This approach considers actual or potential risk, rather than severity, as the main factor for sorting PEP, which improves upon the current approach to emergency classification that is mainly based on the criterion of severity. Regardless of the triage procedure, emergency assessments should no longer classify PEP as “not real emergencies.”Electronic supplementary materialThe online version of this article (doi:10.1186/s12888-016-0727-7) contains supplementary material, which is available to authorized users.

Background: Occupational functioning is severely impaired in patients with bipolar disorder (BD). Work motivation (WM), defined as the psychological processes that determine the direction, intensity, and persistence of action within the work, is an essential component of work-related functioning. Aim: To assess whether WM is affected in patients with BD and which clinical and sociodemographic factors are related to low WM. Methods: In all, 95 euthymic BD patients were invited to answer the Motivation for Work Questionnaire and the Rating Scale on Subjective Cognitive Deficits in Bipolar Disorder (COBRA). Results: A total of 49.5% ( n = 47) of the patients were classified in the Low Motivated (LM) group. Unemployment and the report of more subjective cognitive complaints were predictors of poor WM in this sample ((OR) = 3.01 and 7.10, respectively). Conclusions: Perceived cognitive deficits related to the disorder and current unemployment negatively impact WM in patients with BD. In addition to symptomatic recovery, the need of the inclusion of personal and occupational areas in the comprehensive treatment of patients with BD is necessary.

Background: Depression and anxiety are frequent comorbid conditions in cardiovascular diseases (CVDs); they are related to poor prognosis and higher mortality risk. Health providers need a clinical tool to identify these psychiatric conditions. The 14-item hospital anxiety and depression scale (HADS) is a screening tool used in patients with different medical conditions. Objective: The aim of this study was to evaluate the psychometric properties of the HADS Mexican Spanish version in a broad sample of Mexican patients with CVDs. Materials and Methods: A total of 953 individuals between 18 and 75 years old with ischemic or hypertensive cardiomyopathy were screened with the HADS Mexican Spanish version. Construct validity, internal consistency, and congruence coefficients of the scale were obtained. Results: The results showed two clear factors which correspond to the original two designated domains of the HADS, anxiety, and depression, with adequate reliability values (alpha > 0.80) and high congruence coefficients (> 0.90) when compared to the sample of other validation studies of the HADS. Conclusions: The present study adds evidence of the validity and reliability of the HADS to assess the presence of both depression and anxiety in Mexican patients with CVD. Its central contribution is that it demonstrates its capacity to differentiate the presence and severity of depression and anxiety in this population.
