    OBJECTIVES: Poor adherence to medication treatment can have devastating consequences for patients with mental illness. The goal of this project was to develop recommendations for addressing adherence problems to improve patient outcomes.
    METHODS: The editors identified important topics and questions concerning medication adherence problems in serious mental illness that are not fully addressed in the literature. A survey was developed containing 39 questions (521 options) asking about defining nonadherence, extent of adherence problems in schizophrenia and bipolar disorder, risk factors for nonadherence, assessment methods, and interventions for specific types of adherence problems. The survey was completed by 41 (85%) of the 48 experts to whom it was sent. Results of the literature review and survey were used to develop recommendations for assessing and improving adherence in patients with serious mental illness.
    RESULTS: ASSESSING ADHERENCE: The experts endorsed percentage of medication not taken as the preferred method of defining adherence, with 80% or more of medication taken endorsed as an appropriate cut-off for adherence in bipolar disorder and schizophrenia. Although self- and physician report are the most common methods used to assess adherence in clinical settings, they are often inaccurate and may underestimate nonadherence. The experts recommend that, if possible, clinicians also use more objective measures (e.g., pill counts, pharmacy records, and, when appropriate, serum levels such as are used for lithium). Use of a validated self-report scale may help improve accuracy.
    SCOPE OF THE PROBLEM: The majority of the experts believed the average patient with schizophrenia or bipolar disorder in their practices takes only 51%-70% of prescribed medication. FACTORS ASSOCIATED WITH NONADHERENCE: The experts endorsed poor insight and lack of illness awareness, distress associated with specific side effects or a general fear of side effects, inadequate efficacy with persistent symptoms, and believing medications are no longer needed as the most important factors leading to adherence problems in schizophrenia and bipolar disorder. The experts considered weight gain a side effect that is very likely to lead to adherence problems in patients with schizophrenia and bipolar disorder; sedation was considered a more important contributor to adherence problems in bipolar disorder than schizophrenia. The experts rated persistent positive or negative symptoms in schizophrenia and persistent grandiosity and manic symptoms in bipolar disorder as the most important symptomatic contributors to adherence problems in these illnesses.
    INTERVENTIONS: It is important to identify the specific factors that may be contributing to a patient's adherence problems in order to customize interventions to target those problems. Multiple problems may be involved, requiring a combination of interventions.
    CONCLUSIONS: Adherence problems are complex and multidetermined. The experts recommended customized interventions focused on the underlying causes.

    Throughout the world, antidepressants (AD) and phosphodiesterase-5 inhibitors (PDE-5i) are the commonly prescribed psychopharmacological agents for treating patients with co-morbid mental health problem and sexual dysfunction (SD). The serotonergic and noradrenergic ADs, although effective, are not without any SD adverse-effects, especially erectile dysfunction (ED). ED is a failure to obtain a satisfactory erection for rewarding sexual coitus during the phases of male's sexual arousal. It is recognized as an important reason why non-adherence to treatment was observed in patients who were on AD. AD intervention caused remission to some of the pre- treatment psychopathology of ED. However, in many patients, AD potentially magnified the unwanted sexual sideeffects. This made the situation challenging for the mental health professional. These challenges are based on the complexity of ED, its etiology and the associated risk factors, which further add to its AD side-effect. The neuro-psychopharmacological basis for AD treatment selection was deliberated. Bio-psycho-social interventions are recommended at two pivotal stages. Firstly, a step should be taken for proper assessment (e.g. detailed history, psychosocial and laboratory investigations); and identify few modifiable risk factors for ED and associated mental health issues. Secondly, with guidance of an algorithm pathway, a practical intervention should include strategies such as dose reduction, augmentation or changing to an AD with lesser or no sexual adverse-effects. It is recommended that bupropion and mirtazepine to be prescribed when patients develop adverse sexual effects with serotonin selective reuptake inhibitor (SSRI), serotonin norepinephrine reuptake inhibitor (SNRI) and tricyclic antidepressant (TCA). Few suggestions which may be borne in mind are revising sexual scripts and improving sexual techniques, life-style modifications, psychotherapy and other nonpharmacological approaches which may be beneficial to both patients and their partners.

    Psychotic disorders are recognized as severe mental disorders that rigorously affect patient's personality, critical thinking, and perceptional ability. High prevalence, global dissemination and limitations of conventional pharmacological approaches compel a significant burden to the patient, medical professionals and the healthcare system. To date, numerous orally administered therapies are available for the management of depressive disorders, schizophrenia, anxiety, bipolar disorders and autism spectrum problems. However, poor water solubility, erratic oral absorption, extensive first-pass metabolism, low oral bioavailability and short half-lives are the major factors which limit the pharmaceutical significance and therapeutic feasibility of these agents. In recent decades, nanotechnology-based delivery systems have gained remarkable attention of the researchers to mitigate the pharmaceutical issues related to the antipsychotic therapies and to optimize their oral drug delivery, therapeutic outcomes, and patient compliance. Therefore, the present review was aimed to summarize the available in vitro and in vivo evidences signifying the pharmaceutical importance of the advanced delivery systems in improving the aqueous solubility, transmembrane permeability, oral bioavailability and therapeutic outcome of the antipsychotic agents.

    Objective: To evaluate the prescription pattern of antidepressants in patients with medical co-morbidity from major psychiatric centres in Asia.
    Methods: The Research on Asian Psychotropic Prescription Pattern for Antidepressants (REAP-AD 2013) collected data from 42 psychiatric centres in 10 Asian countries and regions. Antidepressant prescriptions of 2320 patients with various psychiatric disorders were evaluated. Of these, 370 patients who had specified medical co-morbidities formed the study cohort.
    Results: Escitalopram (20%) and mirtazapine (20%) were the most commonly prescribed antidepressants in patients with medical co-morbidity followed by sertraline (16%), trazodone (15%), and paroxetine (12%). Overall, more than half (52%; 247/476) of prescriptions comprised selective serotonin reuptake inhibitors. Slightly less than two-thirds (63%; n = 233) of patients received at least 1 selective serotonin reuptake inhibitor. In addition, 79% of patients were prescribed only 1 antidepressant. The mean number of antidepressants used per patient was 1.25 (standard deviation, 0.56). There were subtle differences in the most preferred antidepressant across medical illnesses such as diabetes mellitus, liver dysfunction, acid peptic disease, and cerebrovascular disease. Differences were also seen in prescription patterns across different countries.
    Conclusion: Although selective serotonin reuptake inhibitors formed the bulk of antidepressant
    prescriptions in the presence of medical co-morbidity, mirtazapine was also commonly used in the presence of medical co-morbidities. Specified medical morbidities do influence the selection of antidepressants.

    Hypersexuality refers to abnormally increased or extreme involvement in any sexual activity. It is clinically challenging, presents trans-diagnostically and there is extensive medical literature addressing the nosology, pathogenesis and neuropsychiatric aspects in this clinical syndrome. Classification includes deviant behaviours, diagnosable entities related to impulsivity, and obsessional phenomena. Some clinicians view an increase in sexual desire as 'normal' i.e. psychodynamic theorists consider it as egodefensive at times alleviating unconscious anxiety rooted in intrapsychic conflicts. We highlight hypersexuality as multi-dimensional involving an increase in sexual activity that is associated with distress and functional impairment. The aetiology of hypersexuality is multi-factorial with differential diagnoses that include major psychiatric disorders (e.g. bipolar disorder), adverse effects of treatments (e.g. levodopatreatment), substance-induced disorders (e.g. amphetamine substance use), neuropathological disorders (e.g. frontal lobe syndrome), among others. Numerous neurotransmitters are implicated in its pathogenesis, with dopamine and noradrenaline playing a crucial role in the neural reward pathways and emotionally- regulated limbic system neural circuits. The management of hypersexuality is determined by the principle of de causa effectu evanescent, if the causes are treated, the effect may disappear. We aim to review the role of pharmacological agents causing hypersexuality and centrally acting agents treating the associated underlying medical conditions. Bio-psycho-social determinants are pivotal in embracing the understanding and guiding management of this complex and multi-determined clinical syndrome.

    HIV management in people who use drugs (PWUD) is typically complex and challenging due to the presence of multiple medical and psychiatric comorbidities as well as social, physical, economic and legal factors that often disrupt the HIV continuum of care. In this review, we describe the individual, health systems and societal barriers to HIV treatment access and care retention for PWUD. In addition, the clinical management of HIV-infected PWUD is often complicated by the presence of multiple infectious and noninfectious comorbidities.

    We have recently shown that the tocotrienol-rich fraction (TRF) of palm oil, a mixture of vitamin E analogs, improves amyloid pathology in vitro and in vivo. However, precise mechanisms remain unknown. In this study, we examined the effects of long-term (10 months) TRF treatment on behavioral impairments and brain metabolites in (15 months old) AβPP/PS1 double transgenic (Tg) Alzheimer's disease (AD) mice. The open field test, Morris water maze, and novel object recognition tasks revealed improved exploratory activity, spatial learning, and recognition memory, respectively, in TRF-treated Tg mice. Brain metabolite profiling of wild-type and Tg mice treated with and without TRF was performed using ultrahigh performance liquid chromatography (UHPLC) coupled to high-resolution accurate mass (HRAM)-orbitrap tandem mass spectrometry (MS/MS). Metabolic pathway analysis found perturbed metabolic pathways that linked to AD. TRF treatment partly ameliorated metabolic perturbations in Tg mouse hippocampus. The mechanism of this pre-emptive activity may occur via modulation of metabolic pathways dependent on Aβ interaction or independent of Aβ interaction.
