RESUMO
OBJECTIVE: The IDEAL Schedule was developed for staging "care needs" in patients with dementia. We here aim to validate the Spanish version, further test its psychometric properties and explore a latent construct for "care needs". METHODS: A multicenter study was done in 8 dementia care facilities across Spain. Patients referred with a reliable ICD-10 diagnosis of dementia (n = 151) were assessed with the IDEAL Schedule by pairs of raters. Inter-rater reliability (intra-class correlation [ICC] coefficients), internal consistency (Cronbach's alpha), and factor analysis were calculated. Convergent validity for individual items was tested against validated Spanish versions of international instruments. RESULTS: Pilot testing with numerical scales supported the feasibility, face, and content validity of the schedule. The psychometric coefficients were good/clinically acceptable: inter-rater reliability (mean ICC = 0.861; 85% of the ICCs > 0.8), internal consistency (global alpha coefficient = 0.74 in 5 nuclear items), and concurrent validity (global score against the Clinical Dementia Rating schedule, r = 0.63; coefficients for individual items ranging from 0.40 to 0.84, all statistically significant, p < 0.05). Internal consistency was low for the "nonprofessional care" and "social support" dimensions. Factor analysis supported a unidimensional solution, suggesting a latent "care needs" construct. CONCLUSION: The Spanish version of the IDEAL Schedule confirms the main psychometric properties of the original version and documents for the first time the convergent validity of individual items. Factor analysis identified a latent construct consistent with the concept "care needs" although 2 dimensions need further psychometric research.

The objective of this study was to evaluate the prevalence and treatment responsiveness of neuropsychiatric symptoms in patients with mild to moderately severe Alzheimer disease recruited in a naturalistic treatment setting in Spain. All the patients, who matched the prescribing recommendations for donepezil and were able to participate in the study, received donepezil (5 to 10 mg/d) for 6 months. The primary outcome measure was the incidence of adverse events. Secondary outcome measures were neuropsychiatric function measured by the Neuropsychiatric Inventory (NPI), the Mini-Mental State Evaluation, and caregiver burden measured by the Zarit scale. Five hundred and twenty-nine patients were included of which 455 completed the study. The mean baseline NPI score was 19.1. Sixty-five patients (12.3%) experienced an adverse event. The most frequent adverse events were diarrhea and agitation (<2%). Seventeen patients (3%) presented with a neuropsychiatric adverse event and 11 (2%) patients presented with a neurologic adverse event over the course of the study. NPI scores improved by 34.4% over the course of the study, with all items showing a statistically significant improvement. Mini-Mental State Evaluation scores and Zarit caregiver burden scores also improved by 1.27 points and 5.9 points, respectively. This study showed a low incidence of adverse events accompanied by an improvement in the neuropsychiatric and cognitive functions in patients with mild to moderately severe Alzheimer disease treated with donepezil in a community setting in Spain. Donepezil also reduced caregiver burden.

Although alterations in the gut microbiota have been linked to the pathophysiology of major depressive disorder (MDD), including through effects on the immune response, our understanding is deficient about the straight connection patterns among microbiota and MDD in patients. Male and female MDD patients were recruited: 46 patients with a current active MDD (a-MDD) and 22 in remission or with only mild symptoms (r-MDD). Forty-five healthy controls (HC) were also recruited. Psychopathological states were assessed, and fecal and blood samples were collected. Results indicated that the inducible nitric oxide synthase expression was higher in MDD patients compared with HC and the oxidative stress levels were greater in the a-MDD group. Furthermore, the lipopolysaccharide (an indirect marker of bacterial translocation) was higher in a-MDD patients compared with the other groups. Fecal samples did not cluster according to the presence or the absence of MDD. There were bacterial genera whose relative abundance was altered in MDD: Bilophila (2-fold) and Alistipes (1.5-fold) were higher, while Anaerostipes (1.5-fold) and Dialister (15-fold) were lower in MDD patients compared with HC. Patients with a-MDD presented higher relative abundance of Alistipes and Anaerostipes (1.5-fold) and a complete depletion of Dialister compared with HC. Patients with r-MDD presented higher abundance of Bilophila (2.5-fold) compared with HC. Thus, the abundance of bacterial genera and some immune pathways, both with potential implications in the pathophysiology of depression, appear to be altered in MDD, with the most noticeable changes occurring in patients with the worse clinical condition, the a-MDD group.

INTRODUCTION: Although it is a troublesome side effect, information on antipsychotic-induced sexual dysfunction is limited. AIM: To evaluate the frequency of sexual dysfunction and its impact on treatment adherence in patients with a psychotic disorder treated with various antipsychotics under routine clinical conditions. METHODS: Subjects included were sexually active male and female patients 18 years of age or older with a diagnosis of schizophrenia, schizophreniform disorder, schizoaffective disorder, or other psychotic disorder. This was a multicenter, cross-sectional, and naturalistic study conducted by 18 investigators. In addition to sexual functioning, we recorded demographic data, psychiatric diagnosis according to the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition), and medication history. MAIN OUTCOME MEASURE: Pyschotropic-Related Sexual Dysfunction Questionnaire (PRSexDQ-SalSex). RESULTS: All the analyses were performed in the 243 evaluable patients. Most patients were males (71%), and the most common diagnosis was schizophrenia (71%). Overall, 46% of the patients exhibited sexual dysfunction according to the assessment with the SalSex (50% of the males and 37% of the females). Only 37% of the patients with sexual dysfuntion spontaneously reported it. Among the patients exhibiting sexual dysfunction, 32% reported to have poor tolerance to the disturbance. With the exception of conventionals depot, which had a very important and greater effect on females' sexual funtioning, the severity and tolerance of sexual dysfunction were worse in males than in females regardless of the antipsychotic studied. In the univariate logistic regression analysis, using olanzapine as a reference category, risperidone (odds ratio [OR] 7.45, 95% confidence interval [CI] 3.73-14.89) and conventionals, depot (OR 4.57, 95% CI 1.72-12.13) and nondepot (OR 4.92, 95% CI 1.43-16.93), showed a significant increased risk of sexual dysfunction. CONCLUSIONS: Our results show that sexual dysfunction is very common in patients receiving long-term treatment with antipsychotics, and it is associated with a great impact in a substantial proportion of patients.

BACKGROUND: Patients with chronic pain frequently display comorbid depression, but the impact of this concurrence is often underestimated and mistreated. The aim of this study was to determine the prevalence of unrecognized major depression and other mood disorders and comorbid unexplained chronic pain in primary care settings and to explore the associated factors.Also, to compare the use of health services by patients with unexplained chronic pain, both with and without mood disorder comorbidity. METHODS: A cross-sectional study was carried out in a sample of primary care centers. 3189 patients consulting for "unexplained chronic pain" were assessed by the Visual Analogue Scales (VAS) and the Primary Care Evaluation of Mental Disorders (PRIME-MD) questionnaire. RESULTS: We report: a) a high prevalence of unrecognized mood disorders in patients suffering from unexplained chronic pain complaints (80.4%: CI 95%: 79.0%; 81.8%); b) a greater susceptibility of women to mood disorders (OR adjusted = 1.48; CI 95%:1.22; 1.81); c) a direct relationship between the prevalence of mood disorders and the duration of pain (OR adjusted = 1.01; CI 95%: 1.01; 1.02) d) a higher comorbidity with depression if the pain etiology was unknown (OR adjusted = 1.74; CI 95%: 1.45; 2.10) and, e) an increased use of health care services in patients with such a comorbidity (p < 0.0001). CONCLUSIONS: The prevalence of undiagnosed mood disorders in patients with unexplained chronic pain in primary care is very high, leading to dissatisfaction with treatment processes and poorer outcomes. Consequently, it seems necessary to explore this condition more regularly in general practice in order to reach accurate diagnoses and to select the appropriate treatment.

Alzheimer's disease (AD) is the most prevalent neurodegenerative condition, especially among elderly people. The presence of cortical ß-amyloid deposition, together with tau phosphorylation and intracellular accumulation of neurofibrillary tangles (NFT) is the main neuropathologic criteria for AD diagnosis. Additionally, a role of inflammatory, mitochondrial, and metabolic factors has been suggested. Tramiprosate binds to soluble amyloid, thus inhibiting its aggregation in the brain. It reduced oligomeric and fibrillar (plaque) amyloid, diminished hippocampal atrophy, improved cholinergic transmission, and stabilized cognition in preclinical and clinical studies. In this narrative review, current information on the efficacy and safety of tramiprosate, both in AD and in other neurocognitive disorders, is presented. Possible directions for future studies with tramiprosate are also discussed.
