The Effectiveness of Lifestyle Interventions to Reduce Cardiovascular Risk in Patients with Severe Mental Disorders: Meta-Analysis of Intervention Studies

Patients with severe mental illness have higher prevalences of cardiovascular risk factors (CRF). The objective is to determine whether interventions to modify lifestyles in these patients reduce anthropometric and analytical parameters related to CRF in comparison to routine clinical practice. Systematic review of controlled clinical trials with lifestyle intervention in Medline, Cochrane Library, Embase, PsycINFO and CINALH. Change in body mass index, waist circumference, cholesterol, triglycerides and blood sugar. Meta-analyses were performed using random effects models to estimate the weighted mean difference. Heterogeneity was determined using i² statistical and subgroups analyses. 26 studies were selected. Lifestyle interventions decrease anthropometric and analytical parameters at 3 months follow up. At 6 and 12 months, the differences between the intervention and control groups were maintained, although with less precision. More studies with larger samples and long-term follow-up are needed.     

Uptake and metabolism of carbamazepine (CBZ) by clam Ruditapes decussatus and its effects in biochemical responses

1. Laboratory experiments were carried out to assess uptake and metabolism of the epilepsy drug, carbamazepine and its consequent biological responses in marine clam (Ruditapes decussatus) a model non-target organism in ecotoxicology.

2. Clams were exposed to two nominal concentrations (C1?=?30?μg/L and C2?=?50?μg/L) of CBZ for a maximum period of 14 days. Analysis of CBZ and their metabolites in clam and water after exposure to two nominal concentrations of the pharmaceutical drug were performed using UPLC-HRMS analysis. CBZ accumulation reached an average tissue concentration of 1241.59 ng/g dw and 1664.33 ng/g dw at low and high nominal concentration, respectively.

3. Furthermore, a metabolite (3-hydroxy-CBZ) was detected in tissues indicating carbamazepine translocation and metabolism inside clam, suspect screening of CBZ glucuronides was also performed by accurate mass extraction but it could not be detected.

4. Activities of antioxidant enzymes superoxide dismutase, catalase and gluthatione-S-transferase generally increased. Change in the contents of glutathione, malondialdehyde and protein carbonyl were also studied.

5. Results indicated that the bioaccumulation of CBZ resulted in the changes of the antioxidant defense system and the production of ROS with the oxidative stress, ultimately induced alteration in lipid peroxidation and protein carbonyl.     

Calidad de vida en personas con depresión y comorbilidad física desde una perspectiva de género

ObjetivoEl objetivo del estudio es describir la percepción de la calidad de vida relacionada con la salud de personas con depresión y comorbilidad física bajo una perspectiva de género. Se incluyeron 380 individuos mayores de 49 años con, al menos, una patología de las siguientes: diabetes, enfermedad obstructiva pulmonar crónica y cardiopatía isquémica, reclutadas en 31 equipos de atención primaria de Cataluña. La calidad de vida se midió con la escala EuroQol (EQ-5D). Además, se recogieron variables sociodemográficas, gravedad de depresión, índice de privación económica y ámbito de residencia. Se evaluó la relación ajustada entre el sexo y las dimensiones de calidad de vida, mediante una regresión logística multivariante.ResultadosEl 81,3% fueron mujeres; la media de edad fue de 68,4 años (DE: 8,8), La media de la escala visual analógica fue de 57,8 (DE: 17,4) en hombres y 55,8 (DE: 18,6) en mujeres. La media del EQ-Health Index fue de 0,74 (DE: 0,17) en hombres y 0,65 (DE: 0,21) en mujeres (p = 0,001). La probabilidad de presentar problemas en las dimensiones del EQ-5D mostró el sexo como factor de más peso (mujer = 1/hombre = 0) en: autocuidado OR: 2,29 (IC 95% 1,04 a 5,07) y actividades cotidianas OR: 3,09 (IC 95% 1,67 a 5,71). La movilidad se asoció con la edad OR: 1,87 (IC 95% 1,22 a 2,86), el ámbito de residencia con el dolor OR: 2,51 (IC 95% 1,18 a 5,34) y el Beck Depression Inventory (BDI) con la ansiedad/depresión OR: 4,77 (IC 95% 1,77 a 12,88).ConclusiónLa percepción en la calidad de vida de las mujeres con depresión y comorbilidad física es inferior a la de los hombres, siendo en ambos casos inferior a la de población general.Palabras clave: Calidad de vida, Depresión, Comorbilidad física, Género, Atención Primaria     

From neural signatures of emotional modulation to social cognition: individual differences in healthy volunteers and psychiatric participants

It is commonly assumed that early emotional signals provide relevant information for social cognition tasks. The goal of this study was to test the association between (a) cortical markers of face emotional processing and (b) social-cognitive measures, and also to build a model which can predict this association (a and b) in healthy volunteers as well as in different groups of psychiatric patients. Thus, we investigated the early cortical processing of emotional stimuli (N170, using a face and word valence task) and their relationship with the social-cognitive profiles (SCPs, indexed by measures of theory of mind, fluid intelligence, speed processing and executive functions). Group comparisons and individual differences were assessed among schizophrenia (SCZ) patients and their relatives, individuals with attention deficit hyperactivity disorder (ADHD), individuals with euthymic bipolar disorder (BD) and healthy participants (educational level, handedness, age and gender matched). Our results provide evidence of emotional N170 impairments in the affected groups (SCZ and relatives, ADHD and BD) as well as subtle group differences. Importantly, cortical processing of emotional stimuli predicted the SCP, as evidenced by a structural equation model analysis. This is the first study to report an association model of brain markers of emotional processing and SCP.     

SEOM clinical guidelines for the treatment of thyroid cancer

Although thyroid cancer represents less than 1% of malignant tumours, its increased incidence detected in recent years and the appearance and development of new drugs targeting specific molecular targets has attracted the attention of the doctors involved in this pathology, especially medical oncologists. For this reason it is important at this critical point, when treatment may be substantially changed, to establish and agree updated guidelines. These guidelines should incorporate the newly developed strategies that, although still preliminary in evidence level, will surely have an important role, especially in relapsed and refractory tumours, which are unsuitable for surgical or radio-iodine treatment. Particular histological and molecular features of these tumours must be taken into account in order to optimise therapeutic approaches.
