There is controversy regarding whether the addition of cover gowns offers a substantial benefit over gloves alone in reducing personnel contamination and preventing pathogen transmission.

Simulated patient care interactions.

To evaluate the efficacy of different types of barrier precautions and to identify routes of transmission.

In randomly ordered sequence, 30 personnel each performed 3 standardized examinations of mannequins contaminated with pathogen surrogate markers (cauliflower mosaic virus DNA, bacteriophage MS2, nontoxigenic Clostridioides difficile spores, and fluorescent tracer) while wearing no barriers, gloves, or gloves plus gowns followed by examination of a noncontaminated mannequin. We compared the frequency and routes of transfer of the surrogate markers to the second mannequin or the environment.

For a composite of all surrogate markers, transfer by hands occurred at significantly lower rates in the gloves-alone group (OR, 0.02; P < .001) and the gloves-plus-gown group (OR, 0.06; P = .002). Transfer by stethoscope diaphragms was common in all groups and was reduced by wiping the stethoscope between simulations (OR, 0.06; P < .001). Compared to the no-barriers group, wearing a cover gown and gloves resulted in reduced contamination of clothing (OR, 0.15; P < .001), but wearing gloves alone did not.

Wearing gloves alone or gloves plus gowns reduces hand transfer of pathogens but may not address transfer by devices such as stethoscopes. Cover gowns reduce the risk of contaminating the clothing of personnel.

Functional impairment is a defining feature of psychotic disorders. A range of factors has been shown to influence functioning, including negative symptoms, cognitive performance and cognitive reserve (CR). However, it is not clear how these variables may affect functioning in first-episode psychosis (FEP) patients. This 2-year follow-up study aimed to explore the possible mediating effects of CR on the relationship between cognitive performance or specific clinical symptoms and functional outcome.

A prospective study of non-affective FEP patients was performed (211 at baseline and 139 at follow-up). CR was entered in a path analysis model as potential mediators between cognitive domains or clinical symptoms and functioning.

At baseline, the relationship between clinical variables or cognitive performance and functioning was not mediated by CR. At follow-up, the effect of attention (p = 0.003) and negative symptoms (p = 0.012) assessed at baseline on functioning was partially mediated by CR (p = 0.032 and 0.016), whereas the relationship between verbal memory (p = 0.057) and functioning was mediated by CR (p = 0.014). Verbal memory and positive and total subscales of PANSS assessed at follow-up were partially mediated by CR and the effect of working memory on functioning was totally mediated by CR.

Our results showed the influence of CR in mediating the relationship between cognitive domains or clinical symptoms and functioning in FEP. In particular, CR partially mediated the relationship between some cognitive domains or clinical symptoms and functioning at follow-up. Therefore, CR could improve our understanding of the long-term functioning of patients with a non-affective FEP.

Previous literature supports antipsychotics’ (AP) efficacy in acute first-episode psychosis (FEP) in terms of symptomatology and functioning but also a cognitive detrimental effect. However, regarding functional recovery in stabilised patients, these effects are not clear. Therefore, the main aim of this study is to investigate dopaminergic/anticholinergic burden of (AP) on psychosocial functioning in FEP. We also examined whether cognitive impairment may mediate these effects on functioning.

A total of 157 FEP participants were assessed at study entry, and at 2 months and 2 years after remission of the acute episode. The primary outcomes were social functioning as measured by the functioning assessment short test (FAST). Cognitive domains were assessed as potential mediators. Dopaminergic and anticholinergic AP burden on 2-year psychosocial functioning [measured with chlorpromazine (CPZ) and drug burden index] were independent variables. Secondary outcomes were clinical and socio-demographic variables.

Mediation analysis found a statistical but not meaningful contribution of dopaminergic receptor blockade burden to worse functioning mediated by cognition (for every 600 CPZ equivalent points, 2-year FAST score increased 1.38 points). Regarding verbal memory and attention, there was an indirect effect of CPZ burden on FAST (b = 0.0045, 95% CI 0.0011–0.0091) and (b = 0.0026, 95% CI 0.0001–0.0006) respectively. However, only verbal memory post hoc analyses showed a significant indirect effect (b = 0.009, 95% CI 0.033–0.0151) adding premorbid IQ as covariate. We did not find significant results for anticholinergic burden.

CPZ dose effect over functioning is mediated by verbal memory but this association appears barely relevant.

Mixed Bipolar patients are those who have co-existing depressive symptoms during mania. These patients are supposed to have a worse evolution.

The objective of this study was to compare the long-term outcomes of patients who had at least one mixed episode with those who experienced only pure manic episodes.

169 outpatients diagnosed of Bipolar I disorder and treated at least during two years were included. 120 patients (71%) complited the follow-up over 10 years. Baseline demographic and clinical variables were included.

The patients with mixed episodes (37%) had a significantly younger mean age at onset comparing with those with manic episodes (25.3 years vs. 30.8 years; p=0.025) they also had more previous mood- incongruent psychotic symptoms χ2= 6.77, p=0.034), more number of hospitalizations (OR= 1.36, 95% CI = 1.14; -1.63; p< 0.001), and more number of episodes (OR= 1.21, 95% CI = 1.10-1.31; p< 0.001). There were no significant differences relating to depressive episodes, alcohol use, drug abuse, suicidal behaviour and suicide attempts.

Age at onset differed significantly between the mixed episode and pure mania groups, with mixed episode patients having a younger age of onset. This is interesting as one of the major results of the study we have found that age at onset mediates some of the factors classically related to outcome in mixed episodes like alcohol abuse and suicide attempts. However, independently of age at onset, these patients represent a especially severe type of bipolar disorder.

Allelic variation in the promoter region of the serotonin transporter (5-HTTpro) contributes for the risk of alcohol dependence (AD). The short allele (S) of this polymorphism has been associated with co-occurring clinical features in severe AD such as depression, early onset or impulsivity. We studied the putative link between this allele and relapse in AD.

60 male alcohol dependent patients were followed for 3 months after withdrawal. Persistent abnormalities in lab tests (GGT and CDT) or failure to show up at scheduled interviews were considered as relapse. PCR amplifying the 5-HTTpro polymorphism from genomic DNA were performed. The impact of the S allele on relapse was assessed by a non-parametric Pearson χ2 test.

67.27 % of the patients relapsed during follow-up. The S allele of the 5-HTTpro was significantly associated with relapse (χ2 = 7.66 ; p < .006) while no other factor influenced relapse.

Responsible for a 5-HT hypo-functioning, the S allele of the 5-HTTpro may be associated with relapse in abstinent alcohol dependent patients, possibly through intermediate phenotypes such as personality features or lack of behavioral inhibition.

To introduce mindfulness pointing out its potentialities when applied in the psychopatology scope.

The authors had proceeded to a research on this third generation cognitive therapy through the bibliographical retraction, from scientific articles and publications. Trying and describing what he is one practical regular one of Mindfulness.

The practice of Mindfulness Practical of Mindfulness divulged in multiple publications, disclosing to be about a new generation of the Cognitive Therapy. It describes its possible clinical applicability in some psycopathologic features, with bigger emphasis in the disturbances of the anxiety. It is proceeded a summary revision from some conceptual boardings and more recent scientific studies.

Psicotherapeutic thechniques based in the practice of Mindfulness can be applied in clinical context complementing the cognitive theory based in the restructuring of the thought with the essential component of acceptance. However it would be very important to appear more randomized control trials that allow to prove its therapeutical effectiveness.

Cloninger's type II is a severe, early-onset, male-limited, genetically influenced, impulsive form of alcoholism. We assessed the association of two gene polymorphisms (TaqI A DRD2 and 5-HTTpro) with Cloninger's typology, as defined by age at onset of alcohol-related problems, and family history of alcohol abuse, which is thought to be more frequent in type II alcoholics.

58 male alcohol dependent patients were discriminated according to age at onset of alcohol-related problems and interviewed about family history of alcoholism. Genomic DNA was extracted and PCR amplifying the studied polymorphisms were performed. The associations between DRD2 (A1 or A2 alleles), 5-HTTpro (L and S alleles), family history and typology were assessed by Pearson chi2 analyses.

While typology was not influenced by any of the studied polymorphisms, a higher rate of general family history of alcohol abuse was still observed in type II patients (χ2= 4.53; p = 0.033). Furthermore, the A1 allele of the DRD2 was significantly associated with paternal history of alcoholism (χ2= 4.66; p = 0.031) and male, first-degree, collateral history of alcoholism (χ2= 4.40; p = 0.036).

Age at onset as main discriminator between type I and type II does not seem to be influenced by TaqI A DRD2 and 5-5HTTpro polymorphisms. However, the A1 allele of the DRD2 may be a marker of male familial alcoholism, which is in line with previous studies showing association between TaqI A DRD2 with some clinical features of type II alcoholism.

To evaluate the 12-months prospective evolution of metabolic and cardiovascular risk factors in patients with types I or II Bipolar Disorder (BD) in Spain.

The BIMET study is a 12-month, prospective, multicentre, naturalistic study which enrolled patients with type I or II BD according to DSM-IV TR criteria. Fasting blood levels of glucose, total, HDL, LDL cholesterol and triglycerides as well as weight, height, waist circumference and blood pressure were recorded. The National Cholesterol Educational Program (NCEP)-ATP III definition was applied to consider presence of metabolic syndrome (MS).

A total of 524 patients were enrolled; 73% type I and 27% type II. 61.9% women, mean age 46.3 years. 28.4% of subjects work regularly. Smokers were 42.2%, 15.1% had a substance abuse history, 34.2% were obese according with WHO criteria (obesity class I; 23.2%, class II; 7.5%, and class III; 3.5%) and overweight was found in 37.4% of sample. Prevalence of diabetes was 7.3%, hypertension was present in 24.7%, 18.5% had cholesterol ≥240 mg/dL and 36.2% had triglycerides ≥150 mg/dL. Overall prevalence of MS was 27.0% (95% CI: 22.7%-31.3%), with 27.3% (22.2%-32.3%) in type I BD and 27.1% (19.0%-36.6%) in type II (p=0.973).

The prevalence of metabolic syndrome in type I / II BD patients was considerably higher than in the general population. As an excess of mortality due to metabolic and cardiovascular reasons pointed out in these patients, it is recommended a close clinical monitoring of such parameters in the routine medical practice.

The possibility of detention for treatment of mental patients may be controversial since introduces the possibility of the judicial power to dominate one's private life.

It is made an analysis of the legal problems in compulsory internment and treatment in mental patients in Portugal.

The diplomas mainly analysed were the Portuguese mental health law, Constitution and Penal Code. The study was based in four legal principles: necessity, proportionality, subsidiary and adequacy whenever a compulsory detention for mental treatment is imposed and the requisites for that decision.

Compulsory internment may only be determined when it is the only way to guarantee that patient is submitted to treatment, and when is deemed proportional to the danger of the legally protected value in question. Restrictions on patient’s fundamental rights shall be those strictly necessary and suitable to the effectiveness of treatment. Compulsory internment may be petitioned by the Public Attorney, patient's legal representative, public health authorities or any person.

In spite of the diversity of criteria for compulsory mental health care across several countries, Portuguese mental health law emphasizes the need for treatment as an essential condition for detaining patients with mental illness. The compulsory treatment is based on the judge decision supported in the psychiatric report. However, how can we be certain that a mental patient is going to practice a specific crime? Is it fair to punish without crime? Are there scientific criteria capable of ensuring that mental patients cause always violent behavior?

Brain volume abnormalities and oxidative cell damage have been reported to be pathological characteristics of schizophrenia patients. This study aims to assess a potential relationship between these two characteristics in child and adolescent patients with first-episode psychosis.

26 child and adolescent patients with first-episode early-onset schizophrenia, and 78 age- and gender-matched healthy controls were assessed. Magnetic resonance imaging (MRI) scans were used for volumetric measurements of five cerebral regions: gray matter of the frontal, parietal, and temporal lobes, sulcal cerebrospinal fluid (CSF), and lateral ventricles. Oxidative cell damage was traced by means of a systemic increase in lipid hydroperoxides (LOOH).

Lateral ventricle volumes were significantly higher in schizophrenia patients than in controls. In schizophrenia patients, a significant positive relationship was found between oxidative cell damage (LOOH levels) and the abnormal enlargement of the lateral ventricles, after controlling for total intracranial volume, age, gender, daily smoking status, intelligence quotient (IQ), psychopathology, and time since onset of psychotic symptoms. No association was found between brain volumes and oxidative cell damage in control subjects.

Our results suggest that, in patients with first-episode early-onset schizophrenia, enlargement of the lateral ventricles is associated with chronic oxidative cell damage.

To estimate the 10-years coronary heart disease and cardiovascular mortality risks in a Spanish population of bipolar disorder (BD) patients.

BIMET study is a 12-month, prospective, multicentre, naturalistic study which enrolled type I or II BD patients according to DSM-IV TR criteria. A fasting blood sample was drawn to evaluate glucose, total cholesterol, HDL cholesterol, LDL cholesterol and triglycerides. Weight, height, waist circumference at the umbilicus and blood pressure were also recorded. Framinghan and SCORE functions were used to calculate the 10-year risk for coronary hearth disease or cardiovascular death respectively.

A total of 320 and 417 patients, mean age 46.3 (13.0) years, were included for the Framingham and SCORE calculations respectively. The overall mean (standard deviation) risk for coronary heart disease was 7.3% (7.8) according to Framingham algorithm, with 6.3% of patients classified as having a high risk of coronary disease (Framingham higher than 10%). The mean overall risk for cardiovascular mortality was 1.2% (2.4) according to SCORE algorithm, with 6.5% of patients falling within the high cardiovascular mortality risk segment; SCORE higher than 5%. No statistically significant differences were observed between type I and II patients.

This study reflects a substantial risk for cardiovascular events or mortality in a Spanish cohort of bipolar disorder patients. Results were comparable to those seen in subject with schizophrenia spectrum disorders. Therefore, an effort for controlling all cardiovascular risk factors in bipolar disorder patients should be carried out by clinicians and health decision makers.

To describe possible differences in the initial cognitive profile between schizophrenia and non-schizophrenia first episode psychosis patients.

We assessed attention, working memory, and executive functioning in 57 first episode psychosis patients at baseline and at a one-year follow-up.

No significant differences were detected in the cognitive profile among schizophrenia (n=20) and non-schizophrenia (n=37) patients at baseline or at the one-year follow-up. For the overall group, significant reductions in the percentage of omission and commission errors for the sustained attention task (p< 0.001 and p=0.001 respectively), in the total time to complete the Stroop-I task (p< 0.001), in the percentage of omission errors for the working memory task (p=0.001), and in the percentage of perseverative errors for the WCST (p< 0.001) were detected, as well as a significant increase in the number of categories completed in the WCST (p< 0.001). The other cognitive variables analyzed remained stable (4 of the 10 variables tested). The pattern of change was similar for schizophrenia and non-schizophrenia patients in the areas of attention and working memory. For executive functioning, the non-schizophrenia group showed a more beneficial pattern of change.

Our results indicate a lack of specificity of cognitive alterations related to the degree of affectation, at least during the first year after instauration of treatment. The course of cognitive deficits in first episode psychosis showed significant improvements over this period, being the patter of change in executive functioning slightly more beneficial for patients with a non-schizophrenia psychosis.
