Predicció de la conducta violenta en interns penitenciaris

En aquest treball exploratori s’ha estudiat les diferencies entre un grup d’interns penitenciaris, de 4 Centres diferents de la Comunitat Autònoma de Catalunya i un grup d’alumnes universitaris de semblants característiques en les seves variables de subjecte de sexe i edat. L’instrument psicològic emprat ha estat el Psicodiagnòstic Miokinètic Revisat i Digitalitzat (PMK-RD) que ha posat de manifest diferències estadísticament significatives en 4 dels 6 trets de personalitat estudiats: excitació, impulsivitat, emotivitat i agressivitat. Ha permès classificar globalment als interns en un 94,7% i els universitaris en un 100 %. Un posterior anàlisis discriminant a partir tan sols d’aquelles variables que han resultat significativament diferents en un i altre grup, ha classificat segons l’excitació i l’emotivitat un 86,8 % d’interns i un 97,4% d’universitaris. L’interès d’aquest treball resideix en que aquestes dades s’han obtingut a partir d’un instrument psicològic que mesura la conducta motora de les persones, a pols i sense visió, o sigui que avalua la influencia de l’activitat propioceptiva, en el control motor de la conducta voluntària. S’ha emprat un disseny de doble cec, segons el qual els administradors de la prova no coneixien que s’avaluava i els correctors de la mateixa no coneixien als participants. Per aquests motius la interpretació dels resultats no es fonamenta en altres fonts ( entrevista, qüestionaris verbals, etc.) que no sigui el test emprat. Els autors consideren que per les seves característiques no verbals i per els resultats aconseguits aquesta prova pot ser un magnífic instrument per a la classificació de les característiques de personalitat d’alt risc per la conducta delictiva i per consegüent útil per a una formació preventiva de les persones, i a tenir en compte per a la rehabilitació de les mateixes.

Risk of type 2 diabetes according to traditional and emerging anthropometric indices in Spain, a Mediterranean country with high prevalence of obesity: results from a large-scale prospective cohort study.

Background: Obesity is a major risk factor for type 2 diabetes mellitus (T2DM). A proper anthropometric characterisation of T2DM risk is essential for disease prevention and clinical risk assessement. Methods: Longitudinal study in 37 733 participants (63% women) of the Spanish EPIC (European Prospective Investigation into Cancer and Nutrition) cohort without prevalent diabetes. Detailed questionnaire information was collected at baseline and anthropometric data gathered following standard procedures. A total of 2513 verified incident T2DM cases occurred after 12.1 years of mean follow-up. Multivariable Cox regression was used to calculate hazard ratios of T2DM by levels of anthropometric variables. Results: Overall and central obesity were independently associated with T2DM risk. BMI showed the strongest association with T2DM in men whereas waist-related indices were stronger independent predictors in women. Waist-to-height ratio revealed the largest area under the ROC curve in men and women, with optimal cut-offs at 0.60 and 0.58, respectively. The most discriminative waist circumference (WC) cut-off values were 99.4 cm in men and 90.4 cm in women. Absolute risk of T2DM was higher in men than women for any combination of age, BMI and WC categories, and remained low in normal-waist women. The population risk of T2DM attributable to obesity was 17% in men and 31% in women. Conclusions: Diabetes risk was associated with higher overall and central obesity indices even at normal BMI and WC values. The measurement of waist circumference in the clinical setting is strongly recommended for the evaluation of future T2DM risk in women.

Development and validation of a risk score predicting substantial weight gain over 5 years in middle-aged European men and women.

BACKGROUND Identifying individuals at high risk of excess weight gain may help targeting prevention efforts at those at risk of various metabolic diseases associated with weight gain. Our aim was to develop a risk score to identify these individuals and validate it in an external population. METHODS We used lifestyle and nutritional data from 53°758 individuals followed for a median of 5.4 years from six centers of the European Prospective Investigation into Cancer and Nutrition (EPIC) to develop a risk score to predict substantial weight gain (SWG) for the next 5 years (derivation sample). Assuming linear weight gain, SWG was defined as gaining ≥ 10% of baseline weight during follow-up. Proportional hazards models were used to identify significant predictors of SWG separately by EPIC center. Regression coefficients of predictors were pooled using random-effects meta-analysis. Pooled coefficients were used to assign weights to each predictor. The risk score was calculated as a linear combination of the predictors. External validity of the score was evaluated in nine other centers of the EPIC study (validation sample). RESULTS Our final model included age, sex, baseline weight, level of education, baseline smoking, sports activity, alcohol use, and intake of six food groups. The model's discriminatory ability measured by the area under a receiver operating characteristic curve was 0.64 (95% CI = 0.63-0.65) in the derivation sample and 0.57 (95% CI = 0.56-0.58) in the validation sample, with variation between centers. Positive and negative predictive values for the optimal cut-off value of ≥ 200 points were 9% and 96%, respectively. CONCLUSION The present risk score confidently excluded a large proportion of individuals from being at any appreciable risk to develop SWG within the next 5 years. Future studies, however, may attempt to further refine the positive prediction of the score.

The association between dietary energy density and type 2 diabetes in Europe: results from the EPIC-InterAct Study

BACKGROUND Observational studies implicate higher dietary energy density (DED) as a potential risk factor for weight gain and obesity. It has been hypothesized that DED may also be associated with risk of type 2 diabetes (T2D), but limited evidence exists. Therefore, we investigated the association between DED and risk of T2D in a large prospective study with heterogeneity of dietary intake. METHODOLOGY/PRINCIPAL FINDINGS A case-cohort study was nested within the European Prospective Investigation into Cancer (EPIC) study of 340,234 participants contributing 3.99 million person years of follow-up, identifying 12,403 incident diabetes cases and a random subcohort of 16,835 individuals from 8 European countries. DED was calculated as energy (kcal) from foods (except beverages) divided by the weight (gram) of foods estimated from dietary questionnaires. Prentice-weighted Cox proportional hazard regression models were fitted by country. Risk estimates were pooled by random effects meta-analysis and heterogeneity was evaluated. Estimated mean (sd) DED was 1.5 (0.3) kcal/g among cases and subcohort members, varying across countries (range 1.4-1.7 kcal/g). After adjustment for age, sex, smoking, physical activity, alcohol intake, energy intake from beverages and misreporting of dietary intake, no association was observed between DED and T2D (HR 1.02 (95% CI: 0.93-1.13), which was consistent across countries (I(2) = 2.9%). CONCLUSIONS/SIGNIFICANCE In this large European case-cohort study no association between DED of solid and semi-solid foods and risk of T2D was observed. However, despite the fact that there currently is no conclusive evidence for an association between DED and T2DM risk, choosing low energy dense foods should be promoted as they support current WHO recommendations to prevent chronic diseases.

Estudio de los exitus con diagnóstico secundario de desnutrición en un hospital de tercer nivel.

BACKGROUND: Malnutrition is a major public health problems, according to WHO, is the leading cause of death, when it affects the group of hospitalized patients, making denominating separate entity "hospital malnutrition". OBJECTIVES: The overall objective is to quantify the main diagnoses frequently high, causing exitus, with secondary diagnosis of malnutrition. METHODS: This is a descriptive study, which included all hospital discharges in 2011 and first half of 2012, which have been exitus and whose secondary diagnosis of malnutrition, with the total of 33. We performed a descriptive analysis, effected the Mann-Whitney nonparametric test (p < 0.05). RESULTS: The most frequent main diagnoses among 33 analyzed are high sepsis (12.1%), liver metastases (9.1%), pneumonia (6.1%), acute respiratory failure (6.1%) and renal acute renal (6.1%). CONCLUSIONS: Although the most frequent primary diagnosis of sepsis, by grouping the diagnoses, the most frequent DRG is respiratory disease, so it has to make comprehensive and quality coding to adjust the relative weight of the same reality. It is essential to specify the source of clinical information used for coding, the degree of malnutrition, for greater specificity in the data.

Irisin is expressed and produced by human muscle and adipose tissue in association with obesity and insulin resistance.

CONTEXT Recently irisin (encoded by Fndc5 gene) has been reported to stimulate browning and uncoupling protein 1 expression in sc adipose tissue of mice. OBJECTIVE The objective of the study was to investigate FNDC5 gene expression in human muscle and adipose tissue and circulating irisin according to obesity, insulin sensitivity, and type 2 diabetes. DESIGN, PATIENTS, AND MAIN OUTCOME MEASURE Adipose tissue FNDC5 gene expression and circulating irisin (ELISA) were analyzed in 2 different cohorts (n = 125 and n = 76); muscle FNDC5 expression was also evaluated in a subcohort of 34 subjects. In vitro studies in human preadipocytes and adipocytes and in induced browning of 3T3-L1 cells (by means of retinoblastoma 1 silencing) were also performed. RESULTS In both sc and visceral adipose tissue, FNDC5 gene expression decreased significantly in association with obesity and was positively associated with brown adipose tissue markers, lipogenic, insulin pathway-related, mitochondrial, and alternative macrophage gene markers and negatively associated with LEP, TNFα, and FSP27 (a known repressor of brown genes). Circulating irisin and irisin levels in adipose tissue were significantly associated with FNDC5 gene expression in adipose tissue. In muscle, the FNDC5 gene was 200-fold more expressed than in adipose tissue, and its expression was associated with body mass index, PGC1α, and other mitochondrial genes. In obese participants, FNDC5 gene expression in muscle was significantly decreased in association with type 2 diabetes. Interestingly, muscle FNDC5 gene expression was significantly associated with FNDC5 and UCP1 gene expression in visceral adipose tissue. In men, circulating irisin levels were negatively associated with obesity and insulin resistance. Irisin was secreted from human adipocytes into the media, and the induction of browning in 3T3-L1 cells led to increased secreted irisin levels. CONCLUSIONS Decreased circulating irisin concentration and FNDC5 gene expression in adipose tissue and muscle from obese and type 2 diabetic subjects suggests a loss of brown-like characteristics and a potential target for therapy.

Després d’aplicar alguns tractaments d’elaboració i conservació als aliments, queden bacteris lesionats. Aquests bacteris perden la capacitat de créixer en els medis de cultiu selectiu convencionals, de manera que se’n subestima el recompte. Malgrat això, poden recuperar-se als aliments i suposar un risc per la salut, ja que alguns encara poden mantenir activitat metabòlica i integritat estructural. En aquest projecte, es van optimitzar protocols de preparació de mostres per citometria de flux (CF) per avaluar l’estat fisiològic de patògens alimentaris (Escherichia coli O157:H7, Salmonella Enteritidis i Listeria monocytogenes) sotmesos a estrès. Es van estudiar principalment dos paràmetres fisiològics: la integritat de membrana, mitjançant iodur de propidi i fluorocroms de la família SYTO; i l’activitat respiratòria, per la reducció intracel•lular d’una sal de tetrazole, el CTC. En primer lloc, es van avaluar variables de protocol, com la concentració de colorant, la ràtio entre colorants, la solució de tinció i el temps d’incubació, en mostres control (cèl•lules sanes i mortes). A continuació, els protocols optimitzats es van aplicar a suspensions bacterianes en medi de cultiu que prèviament havien estat sotmeses a estressos físics i fisicoquímics. Durant l’etapa final del projecte, els coneixements adquirits sobre la preparació de mostres per CF es van aplicar a l’anàlisi de mostres de matriu complexa: amanides comercials inoculades amb E. coli O157:H7. Als assajos amb indicadors d’integritat de membrana en suspensions bacterianes sotmeses a estrès, es van poder quantificar cèl•lules amb la membrana parcialment danyada (presumptes cèl•lules lesionades). El recompte de cèl•lules que mantingueren l’activitat respiratòria després de ser sotmeses a estrès va ser superior al que es va obtenir mitjançant recompte en placa convencional, cosa que va evidenciar la presència de cèl•lules actives però no cultivables. La introducció d’estratègies per reduir les interferències provocades per les partícules alimentàries i l’ús d’un anticòs amb marcatge fluorescent va permetre detectar selectivament les cèl•lules d’E. coli O157:H7 i avaluar-ne la integritat de membrana simultàniament. L’anàlisi de cèl•lules bacterianes per CF requereix de la exhaustiva optimització dels protocols, que són específics per cada soca i matriu. Malgrat això, i a diferència del mètode convencional per recompte en placa, ofereix la possibilitat d’obtenir una gran quantitat d’informació sobre el sovint complex estat fisiològic d’una mostra.

Application of colon capsule endoscopy (CCE) to evaluate the whole gastrointestinal tract: a comparative study of single-camera and dual-camera analysis.

BACKGROUND AND STUDY AIMS Colon capsule endoscopy (CCE) was developed for the evaluation of colorectal pathology. In this study, our aim was to assess if a dual-camera analysis using CCE allows better evaluation of the whole gastrointestinal (GI) tract compared to a single-camera analysis. PATIENTS AND METHODS We included 21 patients (12 males, mean age 56.20 years) submitted for a CCE examination. After standard colon preparation, the colon capsule endoscope (PillCam Colon™) was swallowed after reinitiation from its "sleep" mode. Four physicians performed the analysis: two reviewed both video streams at the same time (dual-camera analysis); one analyzed images from one side of the device ("camera 1"); and the other reviewed the opposite side ("camera 2"). We compared numbers of findings from different parts of the entire GI tract and level of agreement among reviewers. RESULTS A complete evaluation of the GI tract was possible in all patients. Dual-camera analysis provided 16% and 5% more findings compared to camera 1 and camera 2 analysis, respectively. Overall agreement was 62.7% (kappa = 0.44, 95% CI: 0.373-0.510). Esophageal (kappa = 0.611) and colorectal (kappa = 0.595) findings had a good level of agreement, while small bowel (kappa = 0.405) showed moderate agreement. CONCLUSION The use of dual-camera analysis with CCE for the evaluation of the GI tract is feasible and detects more abnormalities when compared with single-camera analysis.

Estudio comparativo de la respuesta inflamatoria peritoneal en la gastrectomía por cáncer: abordaje abierto frente abordaje laparoscópico.

Introducción Estudios en colecistectomías y cáncer colorrectal demostraron que la laparoscopia genera menor respuesta inflamatoria sistémica. Escasos trabajos en cáncer gástrico evalúan el impacto inflamatorio en laparoscopia y emplean metodología deficiente. Hipótesis Demostrar mediante el estudio de tejido peritoneal la menor respuesta inflamatoria(protein-arrays) en pacientes gastrectomizados por laparoscopia vs. vía abierta. Material y métodos 26 pacientes: laparoscópica (12) vs. abierta (14); 2010-2012. Resultados Basados en TNF muestran incremento similar de respuesta a la agresión quirúrgica (aunque hubo diferencias en valores finales en ambos abordajes). Conclusiones Resultados preliminares apuntan hacia conclusiones estadísticamente significativas que apoyen nuestra hipótesis: menor respuesta inflamatoria en laparoscopia y correlación con datos clínicos.

Preinfarction angina prior to first myocardial infarction does not influence long-term prognosis: a retrospective study with subgroup analysis in elderly and diabetic patients.

BACKGROUND AND HYPOTHESIS Although prodromal angina occurring shortly before an acute myocardial infarction (MI) has protective effects against in-hospital complications, this effect has not been well documented after initial hospitalization, especially in older or diabetic patients. We examined whether angina 1 week before a first MI provides protection in these patients. METHODS A total of 290 consecutive patients, 143 elderly (>64 years of age) and 147 adults (<65 years of age), 68 of whom were diabetic (23.4%) and 222 nondiabetic (76.6%), were examined to assess the effect of preceding angina on long-term prognosis (56 months) after initial hospitalization for a first MI. RESULTS No significant differences were found in long-term complications after initial hospitalization in these adult and elderly patients according to whether or not they had prodromal angina (44.4% with angina vs 45.4% without in adults; 45.5% vs 58% in elderly, P < 0.2). Nor were differences found according to their diabetic status (61.5% with angina vs 72.7% without in diabetics; 37.3% vs 38.3% in nondiabetics; P = 0.4). CONCLUSION The occurrence of angina 1 week before a first MI does not confer long-term protection against cardiovascular complications after initial hospitalization in adult or elderly patients, whether or not they have diabetes.
