Abstract
The current study analyzed the influence of burden on the well-being of caregivers by exploring the mediating role of sociocultural and family factors. The study sample comprised 386 Mexican caregivers between ages 19 and 87 (mean age = 49.05; SD =12.41 years). The results from the current research showed that burden scores are negatively associated with well-being, sociocultural, and family scores. However, the effect of burden on subjective well-being is minimized by the mediation effect of sociocultural and family resources between burden and well-being. The complexities of sociocultural and family influences should be taken into account to change the prevailing individualistic approach within the current stress and family caregiver well-being paradigm.

Abstract
The purpose of this study was to characterize behavioral and physiological effects of a selective thromboxane (TP) receptor antagonist, SQ 29,548, in the C57Bl/6 mouse model. At 6 months of age, male mice were given either sham or drug i.p. injections for 3 days at a dose of 2 mg/kg each day. On the day after the final injection, mice were subjected to behavioral testing before brain collection. Left hemisphere hippocampi were collected from all mice for protein analysis via Western blot. Right brain hemispheres were fixed and embedded in gelatin and then serially sectioned. The sections were immunostained with anti-c-Fos antibodies. Prostaglandin analysis was performed from remaining homogenized brain samples, minus the hippocampi. Injection of SQ 29,548 decreased selective brain prostaglandin levels compared with sham controls. This correlated with robust increases in limbic-region c-Fos immunoreactivity in the SQ 29,548-injected mice. However, drug-treated mice demonstrated no significant changes in relevant hippocampal protein levels compared with sham treatments, as determined from Western blots. Surprisingly, injection of SQ 29,548 caused mixed changes in parameters of depression and anxiety-like behavior in the mice. In conclusion, the results indicate that administration of peripheral TP receptor antagonists alters brain levels of prostanoids and influences neuronal activity, with only minimal alterations of behavior. Whether the drug affects neurons directly or through a secondary pathway involving endothelium or other tissues remains unclear.

Abstract
PURPOSE Erectile dysfunction (ED) is common in males with epilepsy, likely of multifactorial etiology, including possible systemic vascular comorbidities and medication effects. Here we examined male patients for the possibility of a vasculogenic element of ED. METHODS Research participants included 47 men with epilepsy (mean age=30.98 years; duration of illness=13.98 years) and 25 healthy matched men (mean age=30.36). Erectile function was assessed using the International Index of Erectile Function Questionnaire (IIEF-5). Penile blood flow was assessed using Duplex Ultrasonography (PDU) after intracavernous alprostadil injection. Penile peak systolic velocity (PSV), end-diastolic velocity (EDV) and resistance index (RI) were the functional parameters analyzed. Carotid artery intima media thickness (CA-IMT) was also measured. RESULTS Thirteen of the 47 men with epilepsy (23.40% versus 0% for controls) reported ED, and of these patients, 11 (84.62%) had abnormal PDU [PSV=28.23 ± 6.1cm/s, P=0.0001; EDV=2.22 ± 5.71 cm/s, P=0.004; RI=0.89 ± 0.22, P=0.071] suggesting vasculogic ED. Penile arterial insufficiency was identified in 5 (45.45%), while 6 (54.54%) had mixed arterial insufficiency and venous leak. Compared to patients with high PSV, patients with low PSV had lower IIED-5 scores, higher EDV, lower RI, higher diastolic blood pressure and higher CA-IMT values. There were no differences in depression, anxiety or concentrations of sex hormones. Significant correlations were evident between PDU variables and duration of illness, depression and anxiety scores and CA-IMT values. In multivariate analysis, the association between PDU parameters and CA-IMT values remained significant even after adjustment for other confounding variables. CONCLUSIONS Vasculogenic ED is frequent with epilepsy and its relationship to systemic atherosclerosis cannot be excluded.

Abstract
BACKGROUND Shank3, a post-synaptic density protein involved in N-methyl-d-aspartate (NMDA) receptor tethering and dendritic spine rearrangement, is implicated in the pathophysiology of bipolar disorder. We hypothesized that elevated baseline plasma Shank3 levels might predict antidepressant response to the NMDA receptor antagonist ketamine. METHODS Twenty-nine subjects with bipolar depression received a double-blind, randomized, subanesthetic dose (.5 mg/kg) ketamine infusion. Of the patients for whom Shank3 levels were collected, 15 completed baseline 3-Tesla MRI and 17 completed post-ketamine [(18)F]-FDG PET. RESULTS Higher baseline Shank3 levels predicted antidepressant response at Days 1 (r=-.39, p=.047), 2 (r=-.45, p=.02), and 3 (r=-.42, p=.03) and were associated with larger average (r=.58, p=.02) and right amygdala volume (r=.65, p=.009). Greater baseline Shank3 also predicted increased glucose metabolism in the hippocampus (r=.51, p=.04) and amygdala (r=.58, p=.02). LIMITATIONS Limitations include the small sample size, inability to assess the source of peripheral Shank3, and the lack of a placebo group for baseline Shank3 levels and comparative structural/functional neuroimaging. CONCLUSIONS Shank3 is a potential biomarker of antidepressant response to ketamine that correlates with baseline amygdala volume and increased glucose metabolism in the amygdala and hippocampus.

Abstract
BACKGROUND This study assessed the efficacy of the Falloon model of psychoeducational family intervention (PFI), originally developed for schizophrenia management and adapted to bipolar I disorder. The efficacy of the intervention was evaluated in terms of improvement of patients׳ social functioning and reduction of family burden. METHODS This was a multicentre, real-world, controlled, outpatient trial carried out in 11 randomly recruited Italian mental health centres. Enroled patients and key-relatives were consecutively allocated either to receive PFI and Treatment As Usual (TAU) or to a waiting list receiving TAU alone. The efficacy of the intervention was evaluated in terms of improvement in patients׳ social functioning (primary outcome) and reduction of family burden (secondary outcome). RESULTS Of the 137 recruited families, 70 were allocated to the experimental group and 67 to the control group. At the end of the intervention, significant improvements in patients׳ social functioning and in relatives׳ burden were found in the treated group compared to TAU. This effect of the intervention remained also after controlling for several confounding patient׳s socio-demographic and clinical factors. The experimental intervention had an impact also on other outcome measures, such as patients׳ clinical status and personal burden. LIMITATIONS Lack of an active control group. CONCLUSIONS The results of this study clearly show that the psychoeducational family intervention according to the Falloon model is effective in improving the social outcome of patients with bipolar I disorder.

Abstract
Both the molecular co-chaperone FKBP51 and the presynaptic vesicle protein synapsin (alternatively spliced from SYN1-3) are intensively discussed players in the still insufficiently explored pathobiology of psychiatric disorders such as major depression, schizophrenia and posttraumatic stress disorder (PTSD). To address their still unknown interaction, we compared the expression levels of synapsin and five other neurostructural and HPA axis related marker proteins in the prefrontal cortex (PFC) and the hippocampus of restrained-stressed and unstressed Fkbp5 knockout mice and corresponding wild-type littermates. In addition, we compared and correlated the gene expression levels of SYN1, SYN2 and FKBP5 in three different online datasets comprising expression data of human healthy subjects as well as of predominantly medicated patients with different psychiatric disorders. In summary, we found that Fkbp5 deletion, which we previously demonstrated to improve stress-coping behavior in mice, prevents the stress-induced decline in prefrontal cortical (pc), but not in hippocampal synapsin expression. Accordingly, pc, but not hippocampal, synapsin protein levels correlated positively with a more active mouse stress coping behavior. Searching for an underlying mechanism, we found evidence that deletion of Fkbp5 might prevent stress-induced pc synapsin loss, at least in part, through improvement of pc Akt kinase activity. These results, together with our finding that FKBP5 and SYN1 mRNA levels were regulated in opposite directions in the PFC of schizophrenic patients, who are known for exhibiting an altered stress-coping behavior, provide the first evidence of a role for pc synapsin in FKBP51 modulation of stress responsiveness. This role might extend to other tissues, as we found FKBP5 and SYN1 levels to correlate inversely not only in human PFC samples but also in other expression sites. The main limitation of this study is the small number of individuals included in the correlation analyses. Future studies will have to verify the here-postulated role of the FKBP51-Akt kinase-synapsin pathway in stress responsiveness.

Abstract
There is an increasing incidence of dementia in our aging population, and consequently an urgent need to develop treatments and activities that may alleviate the symptoms of dementia. Accumulating evidence shows that persons with dementia enjoy music, and their ability to respond to music is potentially preserved even in the late or severe stages of dementia when verbal communication may have ceased. Media interest in this topic has contributed to the public perception that music abilities are an "island of preservation" in an otherwise cognitively impaired person with dementia. In this chapter, we review the current literature on music cognition in dementia and show that there has been very scarce rigorous scientific investigation of this issue, and that various types of music memory exist and are differentially impaired in the different types of dementia. Furthermore, we discuss the recent development of music activities as a nonpharmacological treatment for dementia and highlight the methodological limitations of the current literature on this topic. While it has been reported that music activities can improve behavior, (particularly agitation), mood, and cognition in persons with dementia, recent large-scale randomized control studies have questioned the specificity of the effect of music and found that it is no more beneficial than other pleasant activities. Nevertheless, music is unique in its powerful ability to elicit both memories and emotions. This can provide an important link to individual's past and a means of nonverbal communication with carers, which make it an ideal stimulus for persons with dementia.

Abstract
BACKGROUND Nonadherence to medication is still a major problem in the treatment of schizophrenia. The current longitudinal study investigated whether the patients' attitudes toward treatment correlated with the ratio of observed vs expected plasma levels of antipsychotic drugs as an objective measurement of adherence. METHODS Data of patients starting monotherapy with a new-generation antipsychotic were collected 2, 4, and 12 weeks after the initiation of treatment. Next to the assessment of patients' attitudes toward medication by means of the Drug Attitude Inventory, the ratio of the observed vs expected plasma level was calculated. Antipsychotic-induced side effects were evaluated by means of the Udvalg for Kliniske Undersogelser Side Effect Rating Scale. RESULTS A total of 93 patients were eligible for statistical analysis. About one-half of the ratios of observed vs expected plasma levels ranged from 0.5 to 2 and were considered normal, whereas the other ratios were considered either too low (<0.5) or too high (>2). No consistent correlation between patients' attitude toward drug therapy and the individual ratios of observed vs expected plasma levels of medication was detected. This finding was not affected by side effects. CONCLUSIONS Our results highlight the importance of recognizing the complex nature of adherence to medication in schizophrenia patients. Importantly, we found no consistent correlation between subjective and objective measures of medication adherence. Therefore, monitoring adherence to medication remains a challenge in clinical practice.

Abstract
BACKGROUND Epigenetic drugs like sodium butyrate (NaB) show antidepressant-like effects in preclinical studies, but the exact molecular mechanisms of the antidepressant effects remain unknown. While research using NaB has mainly focused on its role as a histone deacetylase inhibitor (HDACi), there is also evidence that NaB affects DNA methylation. METHODS The purpose of this study was to examine NaB's putative antidepressant-like efficacy in relation to DNA methylation changes in the prefrontal cortex of an established genetic rat model of depression (the Flinders Sensitive Line [FSL]) and its controls (the Flinders Resistant Line). RESULTS The FSL rats had lower levels of ten-eleven translocation methylcytosine dioxygenase 1 (TET1), which catalyzes the conversion of DNA methylation to hydroxymethylation. As indicated by the behavioral despair test, chronic administration of NaB had antidepressant-like effects in the FSL and was accompanied by increased levels of TET1. The TET1 upregulation was also associated with an increase of hydroxymethylation and a decrease of methylation in brain-derived neurotrophic factor (Bdnf), a gene associated with neurogenesis and synaptic plasticity. These epigenetic changes were associated with a corresponding BDNF overexpression. CONCLUSIONS Our data support the antidepressant efficacy of HDACis and suggest that their epigenetic effects may also include DNA methylation changes that are mediated by demethylation-facilitating enzymes like TET1.

Abstract
We studied how maturation influences the organization of functional brain networks engaged during mental calculations and in resting state. Surface EEG measurements from 20 children (8-12 years) and 25 students (21-26 years) were analyzed. Interregional synchronization of brain activity was quantified by means of Phase Lag Index and for various frequency bands. Based on these pairwise estimates of functional connectivity, we formed graphs which were then characterized in terms of local structure [local efficiency (LE)] and overall integration (global efficiency). The overall data analytic scheme was applied twice, in a static and time-varying mode. Our results showed a characteristic trend: functional segregation dominates the network organization of younger brains. Moreover, in childhood, the overall functional network possesses more prominent small-world network characteristics than in early acorrect in xmldulthood in accordance with the Neural Efficiency Hypothesis. The above trends were intensified by the time-varying approach and identified for the whole set of tested frequency bands (from δ to low γ). By mapping the time-indexed connectivity patterns to multivariate timeseries of nodal LE measurements, we carried out an elaborate study of the functional segregation dynamics and demonstrated that the underlying network undergoes transitions between a restricted number of stable states, that can be thought of as "network-level microstates". The rate of these transitions provided a robust marker of developmental and task-induced alterations, that was found to be insensitive to reference montage and independent component analysis denoising.

Abstract
Amino acids play key roles in the function of the central nervous system, and their alterations are implicated in psychiatric disorders. In the search for a biomarker for major depressive disorder (MDD), we used high-performance liquid chromatography to measure amino acids and related molecules in the cerebrospinal fluid (CSF) of 52 patients with MDD (42 depressed and 10 remitted; DSM-IV) and 54 matched controls. Significant differences were found in four amino acid concentrations between the depressed patients and controls. After Bonferroni correction, only ethanolamine (EA) levels remained significantly reduced in depressed patients (nominal P = 0.0000011). A substantial proportion of the depressed patients (40.5%) showed abnormally low CSF EA levels (<12.1 μM) (P = 0.000033; OR = 11.6, 95% CI: 3.1–43.2). When patients with low EA and those with high EA levels were compared, the former had higher scores for overall depression severity (P = 0.0033) and ‘Somatic Anxiety’ symptoms (P = 0.00026). In unmedicated subjects, CSF EA levels showed a significant positive correlation with levels of homovanillic acid (P = 0.0030) and 5-hydroxyindoleacetic acid (P = 0.019). To our knowledge, this is the first study showing that patients with MDD have significantly lower CSF EA concentrations compared with control subjects. CSF EA could be a state-dependent biomarker for a subtype of MDD.

Abstract
BACKGROUND Soluble fragments of the amyloid precursor protein (APP) generated by α- and β-secretases, sAPPα and sAPPβ, have been postulated as promising new cerebrospinal fluid (CSF) biomarkers for the clinical diagnosis of Alzheimer's disease (AD). However, the capacity of these soluble proteins to assemble has not been explored and could be relevant. Our aim is to characterize possible sAPP oligomers that could contribute to the quantification of sAPPα and sAPPβ in CSF by ELISA, as well as to characterize the possible presence of soluble full-length APP (sAPPf). RESULTS We employed co-immunoprecipitation, native polyacrylamide gel electrophoresis and ultracentrifugation in sucrose density gradients to characterize sAPP oligomers in CSF. We have characterized the presence of sAPPf in CSF from NDC and AD subjects and demonstrated that all forms, including sAPPα and sAPPβ, are capable of assembling into heteromers, which differ from brain APP membrane-dimers. We measured sAPPf, sAPPα and sAPPβ by ELISA in CSF samples from AD (n = 13) and non-disease subjects (NDC, n = 13) before and after immunoprecipitation with antibodies against the C-terminal APP or against sAPPβ. We demonstrated that these sAPP heteromers participate in the quantification of sAPPα and sAPPβ by ELISA. Immunoprecipitation with a C-terminal antibody to remove sAPPf reduced by ~30% the determinations of sAPPα and sAPPβ by ELISA, whereas immunoprecipitation with an APPβ antibody reduced by ~80% the determination of sAPPf and sAPPα. CONCLUSIONS The presence of sAPPf and sAPP heteromers should be taken into consideration when exploring the levels of sAPPα and sAPPβ as potential CSF biomarkers.

Abstract
BACKGROUND AND AIM Several studies have raised concerns over consequences of brand-to-generic and generic-to-generic pharmacy-generated medication substitutions in psychiatric and non-psychiatric patients. The purpose of this retrospective study was to assess behavioral and emotional responses of patients with schizophrenia to antipsychotic medication substitution performed by pharmacies. METHODS A group of Polish ambulatory patients with schizophrenia (n = 196) chronically treated with antipsychotic medications were asked whether antipsychotic medication substitution had been proposed by a pharmacist in the last 12 months. Ninety-nine patients answering positively were administered more questions addressing the patient's emotional and behavioral response to the pharmacy proposal. RESULTS The most important findings of the present study can be summarized as follows: (1) approximately half of the patients were confronted with a pharmacy proposal to switch their antipsychotic medications in the last 12 months, (2) one quarter of these patients did not accept the pharmacy switch, (3) a substantial proportion of patients (>40 %) did not receive any explanation from a pharmacist offering medication substitution, (4) pharmacy-generated substitution proposals were mainly associated with negative patient attitudes and negative emotional responses, (5) substitution proposals provoked an unscheduled psychiatric visit in approx. 10 % of patients, (6) despite the negative attitudes reported by patients, the pharmacy switch rarely led to treatment discontinuation, but did provoke a change in drug dosing in 7 % of patients accepting the switch. CONCLUSIONS A pharmacy proposal to switch their antipsychotic medications is a relatively common experience of Polish ambulatory patients with schizophrenia. Pharmacy-generated substitution proposals are mainly associated with negative patient attitudes, but rarely lead to antipsychotic treatment discontinuation in this group of patients.

Abstract
Family interventions for schizophrenia have been amply demonstrated to be effective and are recommended by most of the international clinical guidelines. However, their implementation in the clinical setting as well as in treatment protocols of patients with psychosis has not been fully achieved yet. With the increasing deinstitutionalization of patients, family has begun to assume the role of care performed by psychiatric hospitals, with a high emotional cost for caregivers as well as the recognition of burden experiences. Families have been the substitute in the face of the scarcity of therapeutic, occupational, and residential resources. For this reason, the viability of patients' care by their families has become a challenge. This article aims to discuss the most important aspects of family interventions, their impact on families, and the most important challenges that need to be overcome in order to achieve well-being and recovery in both patients and caregivers.

Abstract
BACKGROUND Relapse is common in schizophrenia, and seriously impacts patients' quality of life and social functioning. Many factors have been identified that may potentially increase the risk of relapse. This study was designed to investigate the relapse rate in the year following hospital discharge among Chinese patients with schizophrenia in the naturalistic condition, and to explore possible risk factors related to relapse. METHODS We conducted a large, multicenter, retrospective, observational study in ten psychiatric hospitals throughout the People's Republic of China. Nine hundred and ninety-two schizophrenic outpatients aged 18-65 years discharged from these hospitals between September 2011 and February 2012 with recovery/improvement of their condition were included in the study. Information about relapse and correlative factors during the year after discharge was collected by telephone interview using a questionnaire. RESULTS Eight hundred and seventy-six of 992 eligible patients completed the telephone survey. Of these patients, 293 (33.4%) had at least one relapse within 1 year after discharge, and 165 (18.8%) were rehospitalized. In respondents' view, the most important factor contributing to relapse was poor medication adherence (50.7%). Approximately 30% of the respondents had a negative attitude toward medication, with the impression that there was no need to take drugs at all or for a long time. Nonadherent patients (37.9%) had a relapse rate that was 2.5-fold higher than adherent patients (54.5% versus 20.7%, P<0.001). The top five risk factors associated with relapse were nonadherence to medication (odds ratio [OR] 4.602, 95% confidence interval [CI] 3.410-6.211), being without work (OR 3.275, 95% CI 2.291-4.681), poor self-care ability (OR 2.996, 95% CI 2.129-4.214), poor interpersonal skills (OR 2.635, 95% CI 1.951-3.558), and hospitalization on more than three occasions (OR 2.299, 95% CI 1.691-3.126). CONCLUSION The 1-year relapse rate after discharge in patients with schizophrenia was 33.5% in our study. The most important risk factor related to relapse was poor medication adherence, which was mainly due to patients having a negative attitude toward their medication. Lack of psychosocial support and a complicated disease history also increased the risk of relapse.

Abstract
PURPOSE OF REVIEW Carers of people with dementia are at increased risk of experiencing psychological distress. This article reviews recent findings on the role of personality traits for psychological outcomes for carers of people with dementia. RECENT FINDINGS Several studies have now established that personality influences the caregiving experience, carer well-being and outcomes such as coping ability, burden and caregiving style. Several moderators of these associations have also been identified such as the effect of kinship and type of dementia. There is consistent evidence that carer personality characteristics influence the progression of the disease such as cognitive decline and severity. Most of the recent studies identified in this review are cross-sectional. SUMMARY Taken together, these results indicate that personality is an important psychological resource for carers. Recent findings indicate that personality traits are associated with and influence both carer and patient outcomes. Future research is necessary to guide interventions and to expand further on our understanding of how personality factors shape adjustment to the caregiving role and how these impact on the progression of the disease.

Abstract
Background. Major depressive disorder (MDD) is the second cause of years lived with disability around the world. A large number of studies have been carried out to identify genetic risk factors for MDD and related endophenotypes, mainly in populations of European and Asian descent, with conflicting results. The main aim of the current study was to analyze the possible association of five candidate genes and depressive symptoms in a Colombian sample of healthy subjects. Methods and Materials. The Spanish adaptation of the Hospital Anxiety and Depression Scale (HADS) was applied to one hundred eighty-eight healthy Colombian subjects. Five functional polymorphisms were genotyped using PCR-based assays: BDNF-Val66Met (rs6265), COMT-Val158Met (rs4680), SLC6A4-HTTLPR (rs4795541), MAOA-uVNTR, and SLC6A3-VNTR (rs28363170). Result. We did not find significant associations with scores of depressive symptoms, derived from the HADS, for any of the five candidate genes (nominal p values >0.05). In addition, we did not find evidence of significant gene-gene interactions. Conclusion. This work is one of the first studies of candidate genes for depressive symptoms in a Latin American sample. Study of additional genetic and epigenetic variants, taking into account other pathophysiological theories, will help to identify novel candidates for MDD in populations around the world.

Abstract
The current study was the first one to reveal the contribution of DRD3 methylation to the risk of different (SCZ) subtypes. This study comprised a total of 30 paranoid (15 males and 15 females) and 29 undifferentiated (15 males and 14 females) SCZ patients and 26 age- and gender-matched controls. Our results showed a significant association of CpG2 with SCZ. A breakdown analysis by gender showed that CpG2 and CpG3 methylation were significantly higher in male patients than male controls, and that CpG5 methylation was significantly higher in female patients than female controls. A further breakdown analysis by both gender and SCZ subtype showed that CpG2 and CpG3 methylation were significantly higher in male paranoid SCZ and male undifferentiated SCZ than male controls. In contrast, CpG2 and CpG3 methylation were significantly lower in female undifferentiated SCZ than female controls. Additionally, CpG5 methylation was significantly higher in female paranoid SCZ than female controls. In conclusion, our findings supported that DRD3 gene body hypermethylation was significantly associated with the risk of SCZ. Future study is needed to clarify the mechanisms by which DRD3 gene body hypermethylation contributes to the risk of SCZ.

Abstract
BACKGROUND In order to reduce the huge treatment gap in mental health, WHO has called for integrating mental health into primary care. The purposes of this study are to provide a training course to improve the community mental health staff's knowledge of mental health and reduce stigma related to mental illness, as well as to evaluate the impact of this training on knowledge and stigma. METHODS The training intervention was a one day course for community mental health staff in Guangzhou, China. Evaluation questionnaires were given before and after the training session. Mental health knowledge was assessed using two vignettes. Stigma was evaluated by the Mental Illness: Clinicians' Attitudes Scale (MICA) and the Reported and Intended Behavior Scale (RIBS). RESULTS A total of 99 community mental health staff from eight regions in Guangzhou, China were recruited for the study. The training course did not lead to a significant improvement of participants' levels of mental health knowledge. The mean score of MICA decreased from 47.92 ± 8.63 to 43.53 ± 9.61 after the training (t = 6.64, P < 0.001). As for the RIBS, the mean scores increased from (14.12 ± 3.90) to (15.38 ± 3.41) at post-test (t = -5.44, P < 0.001), indicating a significant improvement. CONCLUSIONS The results from this study show that the training course is an effective way to improve community mental health staff's attitudes toward people with mental illness in the short term, as well as to lessen the social distance between staff and people with mental illness.

Abstract
Evidence from epidemiological, longitudinal, prospective, double-blinded clinical trials as well as case reports documents age-accelerated atherosclerosis with increased carotid artery intima media thickness (CA-IMT) in patients with epilepsy. These findings raise concern regarding their implications for age-accelerated cognitive and behavioral changes in midlife and risk of later age-related cognitive disorders including neurodegenerative processes such as Alzheimer's disease (AD). Chronic epilepsy, cerebral atherosclerosis, and age-related cognitive disorders including AD share many clinical manifestations (e.g. characteristic cognitive deficits), risk factors, and structural and pathological brain abnormalities. These shared risk factors include increased CA-IMT, hyperhomocysteinemia (HHcy), lipid abnormalities, weight gain and obesity, insulin resistance (IR), and high levels of inflammatory and oxidative stresses. The resulting brain structural and pathological abnormalities include decreased volume of the hippocampus, increased cortical thinning of the frontal lobe, ventricular expansion and increased white matter ischemic disease, total brain atrophy, and β-amyloid protein deposition in the brain. The knowledge that age-accelerated atherosclerosis may contribute to age-accelerated cognitive and behavioral abnormalities and structural brain pathologies in patients with chronic epilepsy represents an important research path to pursue future clinical and management considerations.

Abstract
The use of long-acting injectable antipsychotics (LAIs) in schizophrenia is usually restricted to patients in long-term treatment, who prefer them to oral antipsychotics, and to patients with multiple relapses who have a history of non-adherence. However, preliminary evidence from patients in the early phases of the disease suggest that second generation LAIs may be superior to second generation oral medications with regard to the control of negative symptoms and psychosocial functioning. Moreover, several studies have found that psychiatrists are generally reluctant to prescribe LAI antipsychotics and under-estimate their acceptability by patients. Key elements to take into account when offering a LAI in the early course of schizophrenia should include their potential superiority in allowing early detection of non-adherence and in reducing the number of rehospitalisations and relapses.

Abstract
BACKGROUND Depression and anxiety are common and independent outcome predictors in patients with chronic heart failure (CHF). However, it is unclear whether CHF causes depression. Thus, we investigated whether mice develop anxiety- and depression-like behavior after induction of ischemic CHF by myocardial infarction (MI). METHODS AND RESULTS In order to assess depression-like behavior, anhedonia was investigated by repeatedly testing sucrose preference for 8 weeks after coronary artery ligation or sham operation. Mice with large MI and increased left ventricular dimensions on echocardiography (termed CHF mice) showed reduced preference for sucrose, indicating depression-like behavior. 6 weeks after MI, mice were tested for exploratory activity, anxiety-like behavior and cognitive function using the elevated plus maze (EPM), light-dark box (LDB), open field (OF), and object recognition (OR) tests. In the EPM and OF, CHF mice exhibited diminished exploratory behavior and motivation despite similar movement capability. In the OR, CHF mice had reduced preference for novelty and impaired short-term memory. On histology, CHF mice had unaltered overall cerebral morphology. However, analysis of gene expression by RNA-sequencing in prefrontal cortical, hippocampal, and left ventricular tissue revealed changes in genes related to inflammation and cofactors of neuronal signal transduction in CHF mice, with Nr4a1 being dysregulated both in prefrontal cortex and myocardium after MI. CONCLUSIONS After induction of ischemic CHF, mice exhibited anhedonic behavior, decreased exploratory activity and interest in novelty, and cognitive impairment. Thus, ischemic CHF leads to distinct behavioral changes in mice analogous to symptoms observed in humans with CHF and comorbid depression.

Abstract
Alzheimer's disease is associated with the accumulation of Aβ (amyloid β)-peptides in the brain. Besides their cytotoxic effect on neurons, Aβ-peptides are thought to be responsible for the atherothrombotic complications associated with Alzheimer's disease, which are collectively known as cerebrovascular disease. In the present study, we investigated the effect of Aβ-peptides on human platelet signal transduction and function. We discovered that the 25-35 domain of Aβ-peptides induce an increase in platelet intracellular Ca2+ that stimulates α-granule and dense granule secretion and leads to the release of the secondary agonist ADP. Released ADP acts in an autocrine manner as a stimulant for critical signalling pathways leading to the activation of platelets. This includes the activation of the protein kinases Syk, protein kinase C, Akt and mitogen-activated protein kinases. Ca2+-dependent release of ADP is also the main component of the activation of the small GTPase Rap1b and the fibrinogen receptor integrin αIIbβ3, which leads to increased platelet aggregation and increased thrombus formation in human whole blood. Our discoveries complement existing understanding of cerebrovascular dementia and suggest that Aβ-peptides can induce vascular complications of Alzheimer's disease by stimulating platelets in an intracellular Ca2+-dependent manner. Despite a marginal ADP-independent component suggested by low levels of signalling activity in the presence of apyrase or P2Y receptor inhibitors, Ca2+-dependent release of ADP by Aβ-peptides clearly plays a critical role in platelet activation. Targeting ADP signalling may therefore represent an important strategy to manage the cerebrovascular component of Alzheimer's disease.

Abstract
Although most knowledge regarding antidepressant effects is at the receptor level, the neurophysiological correlates of these neurochemical changes remain poorly understood. Such an understanding could benefit from elucidation of antidepressant effects at the level of neural circuits, which would be crucial in identifying biomarkers for monitoring treatment efficacy of antidepressants. In this study, we recruited 20 first-episode drug-naive major depressive disorder (MDD) patients and performed resting-state functional magnetic resonance imaging (MRI) scans before and after 8 weeks of treatment with a selective serotonin reuptake inhibitor-escitalopram. Twenty healthy controls (HCs) were also scanned twice with an 8-week interval. Whole-brain connectivity was analyzed using a graph-theory approach-functional connectivity strength (FCS). The analysis of covariance of FCS was used to determine treatment-related changes. We observed significant group-by-time interaction on FCS in the bilateral dorsomedial prefrontal cortex and bilateral hippocampi. Post hoc analyses revealed that the FCS values in the bilateral dorsomedial prefrontal cortex were significantly higher in the MDD patients compared to HCs at baseline and were significantly reduced after treatment; conversely, the FCS values in the bilateral hippocampi were significantly lower in the patients at baseline and were significantly increased after treatment. Importantly, FCS reduction in the dorsomedial prefrontal cortex was significantly correlated with symptomatic improvement. Together, these findings provided evidence that this commonly used antidepressant can selectively modulate the intrinsic network connectivity associated with the medial prefrontal-limbic system, thus significantly adding to our understanding of antidepressant effects at a circuit level and suggesting potential imaging-based biomarkers for treatment evaluation in MDD.

Abstract
Music is an important resource for achieving psychological, cognitive, and social goals in the field of dementia. This paper describes the different types of evidence-based music interventions that can be found in literature and proposes a structured intervention model (global music approach to persons with dementia, GMA-D). The literature concerning music and dementia was considered and analyzed. The reported studies included more recent studies and/or studies with relevant scientific characteristics. From this background, a global music approach was proposed using music and sound–music elements according to the needs, clinical characteristics, and therapeutic–rehabilitation goals that emerge in the care of persons with dementia. From the literature analysis the following evidence-based interventions emerged: active music therapy (psychological and rehabilitative approaches), active music therapy with family caregivers and persons with dementia, music-based interventions, caregivers singing, individualized listening to music, and background music. Characteristics of each type of intervention are described and discussed. Standardizing the operational methods and evaluation of the single activities and a joint practice can contribute to achieve the validation of the application model. The proposed model can be considered a low-cost nonpharmacological intervention and a therapeutic–rehabilitation method for the reduction of behavioral disturbances, for stimulation of cognitive functions, and for increasing the overall quality of life of persons with dementia.

Abstract
OBJECTIVE To present the pilot study on the European Portuguese validation of the Confusion Assessment Method (CAM). METHODS The translation process was carried out according to International Society Pharmacoeconomics and Outcomes Research guidelines with trained researchers and inter-rater reliability assessment. The study included 50 elderly patients, admitted (≥24 h) to two intermediate care units. Exclusion criteria were: Glasgow Coma Scale (total score ≤11), blindness/deafness, inability to communicate and not able to speak Portuguese. The sensitivity and specificity of CAM were assessed, with DSM-IV-TR criteria of delirium used as a reference standard. RESULTS Findings revealed excellent inter-rater reliability (k>0.81), moderate sensitivity (73%) and excellent specificity (95%). CONCLUSION These preliminary results suggested that this version emerges as a promising diagnostic instrument for delirium.

Abstract
The neurovascular unit is a key player in brain development, homeostasis, and pathology. Mental stress affects coagulation, while severe mental illnesses, such as recurrent depression and schizophrenia, are associated with an increased thrombotic risk and cardiovascular morbidity. Evidence indicates that the hemostatic system is involved to some extent in the pathogenesis, morbidity, and prognosis of a wide variety of psychiatric disorders. The current review focuses on emerging data linking coagulation and some psychiatric disorders.

Abstract
Major depressive disorder (MDD) is an important public health problem affecting 350 million people worldwide. After decades of study, the pathophysiology of MDD remains elusive, resulting in treatments that are only 30-60% effective. This review summarizes the emerging evidence that implicates impaired mitochondrial bioenergetics as a basis for MDD. It is suggested that impaired mitochondrial bioenergetic function contributes to the pathophysiology of MDD via several potential pathways including: genetics/genomics, inflammation, oxidative stress, and alterations in neuroplasticity. A discussion of mitochondrial bioenergetic pathways that lead to MDD is provided. Evidence is reviewed regarding the mito-toxic or mito-protective impact of various antidepressant medications currently in use. Opportunities for further research on novel therapeutic approaches, including mitochondrial modulators, as stand-alone or adjunct therapy for reducing depression are suggested. In conclusion, while there is substantial evidence linking mitochondrial bioenergetics and MDD, there are currently no clear mitochondrial phenotypes or biomarkers to use as guides in targeting therapies beyond individuals with MDD and known mitochondrial disorders toward the general population of individuals with MDD. Further study is needed to develop these phenotypes and biomarkers, to identify therapeutic targets, and to test therapies aimed at improving mitochondrial function in individuals whose MDD is to some extent symptomatic of impaired mitochondrial bioenergetics.

Abstract
OBJECTIVES This study aims to examine the characteristics of obsessive compulsive disorder (OCD) associated with high levels of schizotypy. METHODS Using the Schizotypal Personality Questionnaire (SPQ) with 177 individuals with OCD, patients with OCD and high levels of schizotypy (OCD-HS) were compared to patients with OCD and low levels of schizotypy (OCD-LS) on a range of clinical characteristics. Self-report and clinician-administered instruments were used. Results were adjusted for the severity of OCD symptoms, age, marital status and comorbidity using logistic regression. RESULTS Patients with OCD-HS were younger and less likely to have been married. OCD-HS was associated with higher rates of symmetry/order obsessions, ordering/arranging compulsions, checking compulsions, co-occurring major depression, post-traumatic stress disorder, substance use disorders and greater general psychopathology. Previously reported associations, such as higher total scores on the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) were not significant when adjusted for differences in demographic variables and comorbidity. CONCLUSIONS Patients with OCD-HS were associated with specific OCD symptoms and comorbid conditions and may warrant a specific treatment approach.

Abstract
Family caregiving is a significant rite of passage experienced by family caregivers of individuals with protracted illness or injury. In an integrative review of 26 studies, we characterized family caregiving from the sociocultural perspective of liminality and explored associated psychosocial implications. Analysis of published evidence on this dynamic and formative transition produced a range of themes. While role ambiguity resolved for most, for others, uncertainty and suffering continued. The process of becoming a caregiver was transformative and can be viewed as a rebirth that is largely socially and culturally driven. The transition to family caregiving model produced by this review provides a holistic perspective on this phenomenon and draws attention to aspects of the experience previously underappreciated. Published 2014. This article is a U.S. Government work and is in the public domain in the USA.

Abstract
Lack of insight is predominant in schizophrenia though the causes are still unclear. The present study was carried on to investigate the effect of three Second Generation Antipsychotics (SGAs) and Haloperidol on insight and the associations among different clusters of symptoms and insight. Fifty-five patients have been recruited at the moment of pharmacological switch needed for psychotic exacerbation, from other antipsychotic drugs to Olanzapine, Aripiprazole, Ziprasidone and Haloperidol. Patients have been followed for 6 months and evaluated at baseline, after 3 months and after 6 months. Regarding the insight improvement, all SGAs resulted more effective than Haloperidol, while no difference was detected among different SGAs. Concerning psychopathology, all SGAs showed a better efficacy than Haloperidol, positive symptoms apart. All SGAs showed a similar efficacy on all domains, except for negative symptoms which resulted less responsive to ziprasidone and haloperidol. An association between improvement of insight and psychopathology was detected. Furthermore, insight appears to be related to psychopathology severity, particularly to negative symptoms. However, the observed different effectiveness of Ziprasidone on negative symptoms and insight suggests that these psychopathological features may be not strictly related and, thus, they may be sustained by different psychopathological processes.

Abstract
BACKGROUND Stigma and discrimination are widely experienced by people with mental illness, even in healthcare settings. The purposes of this study were to assess mental health stigma among community mental health staff in Guangzhou, China and in doing so also to assess the psychometric properties of the Reported and Intended Behaviour Scale (RIBS) - Chinese version. METHODS A cross-sectional survey was undertaken among 214 community mental health staff in Guangzhou from September to November, 2013. The Mental Health Knowledge Schedule (MAKS) and RIBS were administered together with the Mental Illness: Clinicians' Attitudes Scale (MICA) to evaluate staff stigma from the perspective of knowledge, attitudes and behaviour. RESULTS The total scores of RIBS, MAKS and MICA were (11.97 ± 3.41), (16.80 ± 5.39) and (51.69 ± 6.94) respectively. Female staff members were more willing to contact people with mental illness than males (t(212) = -2.85,P = 0.005) and had more knowledge about mental illness (t(212) = -2.28,P = 0.024). The Chinese version of RIBS had good internal consistency (alpha = 0.82), test-retest reliability (r = 0.68,P < 0.001) and adequate convergent validity, as indicated by a significant negative correlation with the Chinese version of MICA(r = -0.43, P < 0.001). CONCLUSIONS Our results show relatively high levels of stigma toward people with mental illness among community mental health staff in Guangzhou, China. There are slightly gender differences in discriminatory behaviours and stigma related knowledge of mental illness among community mental health staff, with female staff in general less stigmatising. Accordingly, anti-stigma programmes should be established among healthcare staff. In addition, the Chinese version of RIBS is a reliable, valid and acceptable measure which can be used to assess the willingness of participants to contact people with mental illness in future anti-stigma campaigns.

Abstract
Platelets, known for their role in primary haemostasis, prevent excessive bleeding after injury. The study of platelets has, therefore, traditionally focused on bleeding disorders. It has recently become evident, however, that platelet research can contribute to unravelling the disease mechanisms that underlie neuropathological disorders that have a subtle subclinical platelet phenotype. Platelets and neurosecretory cells have common gene expression profiles and share several biological features. This review provides a literature update on the use of platelets as easily accessible cells to study neurological disorders. We provide examples of the use of different platelet-based tests to understand the underlying pathophysiological mechanisms for both complex and monogenetic neuropathological disorders. In addition to the well-studied regulated granule secretion and serotonin metabolism, more recent studies have shown that defects in transcription factors, membrane transporters, G-protein signal transduction, and cytoskeletal proteins can be investigated using platelets to gain information on their role in neuropathology.

Abstract
Human plasma inhibits arachidonic acid metabolism and platelet aggregation. This helps human form a haemostatic control system that prevents the progress of certain aggregatory or inflammatory reactions. Whether this property of plasma is unique to human or extends to other species is not well known. It is speculated that this protective ability of plasma remains evolutionarily conserved in different mammals. In order to confirm this, the effect of plasma from 12 different mammalian species was investigated for its inhibitory potential against arachidonic acid metabolism and platelet aggregation. Metabolism of arachidonic acid by cyclooxygenase and lipoxygenase pathways was studies using radio-immuno assay and thin layer chromatography while platelet aggregation in the plasma of various mammals was monitored following turbedmetric method in a dual channel aggregometer. Results indicate that inhibition of AA metabolism and platelet aggregation is a common feature of plasma obtained from different mammalian species, although there exists large interspecies variation. This shows that besides human, other mammals also possess general protective mechanisms against various aggregatory and inflammatory conditions and this anti-inflammatory property of the plasma is evolutionarily conserved in mammalian species. The most likely candidates responsible for these properties of plasma include haptoglobin, albumin and lipoproteins.

Abstract
Delirium is a common, but an often underdiagnosed complication in the elderly following major surgery. Recognising delirium in early stages and diagnosing the condition based on established criteria can improve the outcome and management. Managing delirium with environmental, supportive and pharmacological interventions will possibly reduce the incidence and side-effects associated with post-operative delirium. The purpose of this article is to provide an over view of the current knowledge about the disease, diagnosis, pathogenesis, preventive strategies, and treatment of post-operative delirium.

Abstract
Patients with heart disease and depression have an increased mortality rate. Both behavioral and biologic factors have been proposed as potential etiologic mechanisms. Given that the pathophysiology of depression is considered to involve disruption in brain serotonergic signaling, we investigated platelet response to serotonin stimulation in patients with stable coronary artery disease (CAD). We enrolled 92 patients with stable CAD. Platelet response to increasing concentrations of serotonin (5-HT), epinephrine-augmented 5-HT, and adenosine diphosphate (ADP) was measured by optical aggregation and flow cytometry. As concentrations of 5-HT and ADP increased, so did the activation and aggregation of the platelets. However, on addition of the highest concentration of 5-HT (30 μM), a significant decrease in platelet activation (p=0.005) was detected by flow cytometry. This contrasts the increase in platelet activation seen with the addition of the highest concentration of ADP. In conclusion, we found increased platelet activation and aggregation with increased concentrations of ADP; however, when platelets are stimulated with a high concentration of 5-HT (30 μM), there is decreased platelet activation. The data demonstrate unique patterns of platelet activation by 5-HT in patients with stable CAD. The cause of this phenomenon is unclear. Our study sheds light on the in vitro response of platelet function to serotonin in patients with stable CAD, which may further the mechanistic understanding of heart disease and depression.

Abstract
Schizophrenia (SCZ) is a severe complex psychiatric disorder that generates problems for the associated family and society and causes disability with regards to work for patients. The aim of the present study was to assess the contribution of 10 genetic polymorphisms to SCZ susceptibility. Meta-analyses were conducted using the data without a limitation for time or language. A total of 27 studies with 7 genes and 10 polymorphisms were selected for the meta-analyses. Two polymorphisms were found to be significantly associated with SCZ. SNAP25 rs3746544 was shown to increase the SCZ risk by 18% [P=0.01; odds ratio (OR), 1.18; 95% confidence interval (CI), 1.05-1.34] and GRIK3 rs6691840 was found to increase the risk by 30% (P=0.008; OR, 1.30; 95% CI, 1.07-1.58). Significant results were found under the dominant (P=0.001; OR, 1.36; 95% CI, 1.13-1.65) and additive (P=0.02; OR, 1.45; 95% CI, 1.06-1.98) model for the SNAP25 rs3746544 polymorphism and under the additive model for the GRIK3 rs6691840 polymorphism (P=0.03; OR, 1.73; 95% CI, 1.04-2.85). There were no significant results observed for the other eight polymorphisms, which were CCKAR rs1800857, CHRNA7 rs904952, CHRNA7 rs6494223, CHRNA7 rs2337506, DBH Ins>Del, FEZ1 rs559668, FEZ1 rs597570 and GCLM rs2301022. In conclusion, the present meta-analyses indicated that the SNAP25 rs3746544 and GRIK3 rs6691840 polymorphisms were risk factors of SCZ, which may provide valuable information for the clinical diagnosis of SCZ.

Abstract
Huntington’s disease (HD) is a progressive and fatal neurodegenerative disorder caused by an expanded trinucleotide CAG sequence in huntingtin gene (HTT) on chromosome 4. HD manifests with chorea, cognitive and psychiatric symptoms. Although advances in genetics allow identification of individuals carrying the HD gene, much is still unknown about the mechanisms underlying the development of overt clinical symptoms and the transitional period between premanifestation and manifestation of the disease. HD has no cure and patients rely only in symptomatic treatment. There is an urgent need to identify biomarkers that are able to monitor disease progression and assess the development and efficacy of novel disease modifying drugs. Over the past years, neuroimaging techniques such as magnetic resonance imaging (MRI) and positron emission tomography (PET) have provided important advances in our understanding of HD. MRI provides information about structural and functional organization of the brain, while PET can detect molecular changes in the brain. MRI and PET are able to detect changes in the brains of HD gene carriers years ahead of the manifestation of the disease and have also proved to be powerful in assessing disease progression. However, no single technique has been validated as an optimal biomarker. An integrative multimodal imaging approach, which combines different MRI and PET techniques, could be recommended for monitoring potential neuroprotective and preventive therapies in HD. In this article we review the current neuroimaging literature in HD.

Abstract
About half or more of the patients with chronic psychiatric illnesses, either do not take their medications correctly, or completely stop taking them. The problem of poor initial compliance or adherence is often compounded by a continued decline in compliance/adherence over time. The failure to take medicines, adversely affects the outcome of treatment, and places a huge burden of wasted resources on the society. Three terms have been used to describe medication-taking among patients with chronic psychiatric disorders. Compliance is defined as “the extent to which the patient’s behaviour matches the prescriber’s recommendations”. Though compliance has been frequently employed to describe medication-taking behaviour, it has proved problematic because it refers to a process where the clinician decides on a suitable treatment, which the patient is expected to comply with unquestioningly. Studies over the past few decades have emphasized the importance of patients’ perspectives in medication-taking, based on their own beliefs, their personal circumstances, the information and resources available for them. Adherence has been used as a replacement for compliance in an effort to place the clinician-patient relationship in its proper perspective. Adherence refers to a process, in which the appropriate treatment is decided after a proper discussion with the patient. It also implies that the patient is under no compulsion to accept a particular treatment, and is not to be held solely responsible for the occurrence of non-adherence. Adherence has been defined as “the extent to which a person’s behaviour, taking medication, following a diet, and/or executing lifestyle changes, corresponds with agreed recommendations from a health care provider”. To overcome certain problems in the concept of adherence, a third term concordance has been used. The concept of concordance has evolved from a narrower view, emphasizing an agreement between the clinician and the patient, which takes into account each other’s perspective on medication-taking, to a broader process consisting of open discussions with the patient regarding medication-taking, imparting information and supporting patients on long-term medication. It is a process, which entertains patients’ views on medication-taking, and acknowledges that patients’ views have to be respected even if they make choices, which appear to be in conflict with the clinician’s views. Although none of these terms are ideal solutions to understanding the complex process of medication-taking behaviour of patients, the move from compliance to adherence and concordance represents genuine progress in this field, which puts the patient’s perceptions at the centre of the whole process.

Abstract
Peripheral biomarkers play an indispensable role in quick and reliable diagnoses of any kind of disease. With the population ageing, the number of people suffering from age-related diseases is expected to rise dramatically over the coming decades. In particular, all types of cognitive deficits, such as Alzheimer’s disease, will increase. Alzheimer’s disease is characterised mainly by coexistence of amyloid plaques and neurofibrillary tangles in brain. Reliable identification of such molecular characteristics antemortem, however, is problematic due to restricted availability of appropriate sample material and definitive diagnosis is only possible postmortem. Currently, the best molecular biomarkers available for antemortem diagnosis originate from cerebrospinal fluid. Though, this is not convenient for routine diagnosis because of the required invasive lumbar puncture. As a consequence, there is a growing demand for additional peripheral biomarkers in a more readily accessible sample material. Blood platelets, due to shared biochemical properties with neurons, can constitute an attractive alternative as discussed here. This review summarises potential platelet Alzheimer’s disease biomarkers, their role, implication, and alteration in the disease. For easy comparison of their performance, the Hedge effect size was calculated whenever data were available.

Abstract
Insight into the biological pathomechanism of a clinical syndrome facilitates the development of effective interventions. This paper applies this perspective to the important clinical problem of obsessive-compulsive symptoms (OCS) occurring during the lifetime diagnosis of schizophrenia. Up to 25% of schizophrenia patients suffer from OCS and about 12% fulfil the diagnostic criteria of obsessive-compulsive disorder (OCD). This is accompanied by marked subjective burden of disease, high levels of anxiety, depression and suicidality, increased neurocognitive impairment, less favourable levels of social and vocational functioning, and greater service utilization. Comorbid patients can be assigned to heterogeneous subgroups. It is assumed that second generation antipsychotics (SGAs), most importantly clozapine, might aggravate or even induce second-onset OCS. Several epidemiological and pharmacological arguments support this assumption. Specific genetic risk factors seem to dispose patients with schizophrenia to develop OCS and risk-conferring polymorphisms has been defined in SLC1A1, BDNF, DLGAP3, and GRIN2B and in interactions between these individual genes. Further research is needed with detailed characterization of large samples. In particular interactions between genetic risk constellations, pharmacological and psychosocial factors should be analysed. Results will further define homogeneous subgroups, which are in need for differential causative interventions. In clinical practise, schizophrenia patients should be carefully monitored for OCS, starting with at-risk mental states of psychosis and longitudinal follow-ups, hopefully leading to the development of multimodal therapeutic interventions.
