Aims Disturbances in personality and addictions are associated with an increased risk of committing crimes and therefore of being imprisoned. In this study, the relationship between these factors is analyzed through a sample of inmates in the Prison of Pereiro de Aguiar, Ourense. Material and method 204 inmates participated in this transversal simple blind design study. The following variables were analyzed: presence of personality disorders and psychopathy, history of addictive psychoactive substance use, criminal history and socio-demographic variables. Results 101 (49.5%) inmates received a diagnosis of personality disorder, the most frequent being: narcissistic, 43 (21.08%); antisocial, 38 (18.63%); and paranoid, 29 (14.22%). The presence of any personality disorder was associated with an increase in the risk of committing crimes, especially violence and crimes against property. The most frequent personality disorders were associated with higher scores in the psychopathy assessment tools. Higher scores in the Psychopathy Checklist Reviewed (PCL-R) correlated with an increased risk of committing the following crimes: violent, against public health, against property and disorderly conduct. The consumption of addictive psychoactive substances was associated with the commission of crimes against property. Methadone stood out for its protective role against the commission of violent crimes. Discussion This sample shows that inmates have a higher prevalence of personality disorders, psychopathy and consumption of addictive psychoactive substances. These three variables significantly increased the risk of committing crimes.

Objective Recently, the DSM-5 has developed a new diagnostic category named "Substance-related and Addictive Disorders". This category includes gambling disorder (GD) as the sole behavioral addiction, but does not include sex addiction (SA). The aim of this study is to investigate whether SA should be classified more closely to other behavioral addictions, via a comparison of the personality characteristics and comorbid psychopathology of individuals with SA with those of individuals with GD, which comes under the category of addiction and related disorders. Method The sample included 59 patients diagnosed with SA, who were compared to 2190 individuals diagnosed with GD and to 93 healthy controls. Assessment measures included the Diagnostic Questionnaire for Pathological Gambling, the South Oaks Gambling Screen, the Symptom CheckList-90 Items-Revised and the Temperament and Character Inventory-Revised. Results No statistically significant differences were found between the two clinical groups, except for socio-economic status. Although statistically significant differences were found between both clinical groups and controls for all scales on the SCL-90, no differences were found between the two clinical groups. The results were different for personality characteristics: logistic regression models showed that sex addictive behavior was predicted by a higher education level and by lower scores for TCI-R novelty-seeking, harm avoidance, persistence and self-transcendence. Being employed and lower scores in cooperativeness also tended to predict the presence of sex addiction. Conclusions While SA and GD share some psychopathological and personality traits that are not present in healthy controls, there are also some diagnostic-specific characteristics that differentiate between the two clinical groups. These findings may help to increase our knowledge of phenotypes existing in behavioral addictions.

The biolipid sphingosine-1-phosphate (S1P) is an essential modulator of innate immunity, cell migration, and wound healing. It is released locally upon acute tissue injury from endothelial cells and activated thrombocytes and, therefore, may give rise to acute post-traumatic pain sensation via a yet elusive molecular mechanism. We have used an interdisciplinary approach to address this question, and we find that intradermal injection of S1P induced significant licking and flinching behavior in wild-type mice and a dose-dependent flare reaction in human skin as a sign of acute activation of nociceptive nerve terminals. Notably, S1P evoked a small excitatory ionic current that resulted in nociceptor depolarization and action potential firing. This ionic current was preserved in “cation-free” solution and blocked by the nonspecific Cl− channel inhibitor niflumic acid and by preincubation with the G-protein inhibitor GDP-β-S. Notably, S1P3 receptor was detected in virtually all neurons in human and mouse DRG. In line with this finding, S1P-induced neuronal responses and spontaneous pain behavior in vivo were substantially reduced in S1P3−/− mice, whereas in control S1P1 floxed (S1P1fl/fl) mice and mice with a nociceptor-specific deletion of S1P1−/− receptor (SNS-S1P1−/−), neither the S1P-induced responses in vitro nor the S1P-evoked pain-like behavior was altered. Therefore, these findings indicate that S1P evokes significant nociception via G-protein-dependent activation of an excitatory Cl− conductance that is largely mediated by S1P3 receptors present in nociceptors, and point to these receptors as valuable therapeutic targets for post-traumatic pain., The authors thank K.

To assess the initial treatment persistence with inhaled corticosteroids and long-acting beta-2 adrenergic bronchodilators (ICS/LABA) depending on the inhaler device used (pMDI or DPI), for the treatment of asthma and COPD.An multicenter observational study. Subjects in initial treatment with ICS/LABA during 2007-2011 were included, and a follow-up period of 3 years. 2 groups of study (asthma, COPD) and 2 subgroups were prepared according to the device type inhaler (pMDI or DPI). The main measurements were: sociodemographic, comorbidity, adherence (rate possession medication -RPM-), persistence, drugs, exacerbation rates, resources use, and their costs (direct and indirect costs). Multivariate methods were used for the variables correction, with significance level of P.05.The study included 2,082 asthma patients (pMDI: N = 566, 27.2%; DPI = 1,516, 72.8%). Patients with MDI devices showed a higher degree of persistence (32.5 vs. 27.8%; P=.037), treatment adherence (RPM: 83.1 vs. 80.5%; P.001), fewer exacerbations (17.7 vs. 24.9%; P=.001) and lower health care costs (2,583 vs. 2,938 EUR; P = 0.042). 1,418 patients with COPD also were analyzed (pMDI: N = 524, 41.9%; DPI: N = 824, 58.1%) were analyzed. Patients with MDI devices also showed a higher degree of persistence (31.5 vs. 24.8%; P=.005), treatment adherence (RPM: 83.3 vs. 80.1%; P= .001), less exacerbations (40.1 vs. 48.2%; P=.002) and lower health care costs (3,922 vs. 4,588 EUR; P=.021).pMDI devices (as ICS/LABA initial treatment) are associated with higher treatment persistence either in asthma or COPD, with lower exacerbation rates, and use of health resources and cost.

Summary Background Imported cases of malaria constitute an important public health problem in many countries, even in those with autochthonous cases, where disease could be acquired in these areas and then seen in non-endemic regions. Non-immune populations are susceptible to complications due to malaria infection, particularly in malaria caused by Plasmodium falciparum . However, Plasmodium vivax the predominant Plasmodium spp. in Venezuela can also lead to severe malaria. Methods We reviewed retrospectively cases of malaria to identify the clinical features of those imported cases diagnosed at two institutions in Margarita Island (a non-endemic area), Venezuela, in an 8-year period. We conducted a retrospective observational study to identify the clinical and epidemiological features among hospitalized patients at Hospital Central and Hospital Agustin Hernandez with malaria acquired at malaria-endemic locations. Results We identified eighteen imported cases of malaria confirmed by thin and thick peripheral blood smears at these two institutions over an 8-year period. The mean age of diagnosis was 27 years. P. vivax was responsible for the majority of cases. All patients presented with fever, 89% with malaise, 78% with chills, and 67% with myalgia, among others symptoms. Mean haemoglobin levels on admission were 8.1 g/dL (100% 3 (89% had platelets below 150,000); and a mean total leukocyte count: 3.4 × 10 3 cells/mm 3 (78% had leukopenia). Thirty nine percent of patients required blood transfusions. Two fatalities were identified (CFR = 11%), one associated to severe malaria due to P. falciparum and the other due to a complicated case of P. vivax malaria. Discussion Imported cases of malaria due to P. vivax and P. falciparum in the studied population are associated with significant hematological complications. These findings illustrate the importance of educating non-immune populations about the malaria risk and prevention strategies; and from a pubic health perspective, the need to develop further malaria prevention strategies at a national level.

Background: Chronic obstructive pulmonary disease (COPD) is currently the fourth cause of mortality and morbility in the developed world. Patients with COPD experience a progressive deterioration of health-related quality of life (HRQOL). A new model of severity classification, the body mass index, bronchial obstruction, dyspnoea, exercise (BODE) index, has recently been proposed. Objective: To evaluate the relationship between HRQOL and the BODE index, and the predictive ability of BODE on HRQOL measurements. Methods: Two HRQOL questionnaires were administered, namely the Nottingham Health Profile (NHP) and St George's Respiratory Questionnaire (SGRQ), in a sample of 67 patients with severe COPD. Results: Pearsonś correlation coefficient analysis shows a positive correlation between the BODE index and the total scores of the specific ( P < 0.001), and general HRQOL ( P < 0.001); the analysis shows a significant correlation between the BODE index and the subscales of symptoms, activity and impact of SGRQ ( P < 0.001) and the subscales energy and physical mobility of the NHP ( P < 0.001). The regression analysis shows that the BODE index is a significant predictor of HRQOL, explaining 46,1% of the total score of the SGRQ ( P < 0.001) and 14.8% of the total score of the NHP ( P < 0.001). Conclusions: The BODE index is good at predicting the worsening of HRQOL in patients with severe COPD. Chronic Respiratory Disease 2008; 5: 7—11

Objective The objective of this study was to describe tissue procurement activity performed during 10 years (2004–2014) by trained medical students in a large university hospital. Methods In this study, third to sixth year medical students were trained as in-hospital Tissue Coordinators (Tc) to perform tissue procurement activity on a 24/7 schedule supervised by an on-call senior Transplant Coordinator (sTC) in a large university hospital. Tc duty consisted of detection, initial evaluation of all hospital deaths, donor's family approach for tissue donation, and retrieval logistics organization, including corneal tissue retrieval after training and certification. They also assist sTC in organ procurement activity. Results A total of 18,931 deaths were prospectively evaluated, 79% of whom (n = 14,879) presented medical contraindications for tissue donation. Of the remaining 4052 (21%) potential tissue donors (PTD), 2522 (62%) were not converted into real donors, mostly due to family refusal (66%; n = 1650) followed by detection system failure and other logistical issues (34%; n = 872). A total of 2814 corneal units, 225 skin donations, 327 muscleskeletal tissue donations, 91 blood vessels donations, and 177 heart valve donations were obtained from the remaining 1530 (38%) real donors. Tissue potentiality increased from 19% to 43% throughout the study period as a consequence of the fluctuating acceptance criteria used by tissue banks depending on tissue demand. Conclusions The tissue donation program performed by trained students was successful in achieving a high and sustainable tissue donation rate in a large university hospital.

Summary Background Surgical site infection (SSI) after colorectal procedures represents a measurable quality indicator of a healthcare system. There is an increasing interest in comparing SSI rates between different hospitals and countries: however, the variability of the data regarding the incidence of SSI makes this comparison difficult. For the purposes of evaluation, data collection must be standardized and must include reliable post-discharge surveillance (PDS). Aim To determine impact and risk factors for PDS SSI after elective colorectal surgery. Methods VINCat is a nosocomial infection surveillance programme in Catalonia, Spain. Between 2007 and 2011, 52 hospitals joined the programme. Hospitals performed active, prospective, standardized surveillance of elective colorectal resection. PDS was implemented by a multimodal approach and was mandatory within the first 30 days after surgery. Findings During the study period, 13,661 elective colorectal procedures were included. SSI was diagnosed in 2826 (20.7%) patients, of whom 22.5% during PDS; of these, 52% required readmission. Patients with PDS SSI were younger (odds ratio: 1.57; 95% confidence interval: 1.29–1.91), predominantly female (1.40; 1.16–1.69), had more frequently undergone endoscopic procedures (1.56; 1.30–1.88) and had more incisional SSI (1.88; 1.54–2.28) than patients with in-hospital SSI. Conclusion SSI rates in elective colorectal procedures at VINCat hospitals were inside the higher range of those reported by other national programmes. PDS SSI increased the overall rate of SSI, had a significant clinical impact, and accounted for almost a quarter of SSI. Younger age and laparoscopic procedures were the most relevant risk factors. Standardized multimodal PDS should be implemented for hospitals performing surveillance of colorectal surgery.

To evaluate the effectiveness of NEPs in prison to reduce the prevalence of infections associated with intravenous drug use and to know more about acceptance of the program by inmates and staff.cross-sectional observational study at baseline, 6 and 12 months and 10 years of program development. Interviews were conducted with program users, as well as random sample surveys of officials at the various cuts, and a random sample of inmates from the centre after10 years. Activity indicators of the program were recorded continuously, and the prevalence of HIV, HBV and HCV at baseline and after 10 years was evaluated. For the statistical analysis, the chi-square test was used with the Yates correction when necessary.In ten years we have supplied a total of 15,962 syringes to 429 users, (average 20.2 users/month), and 11,327 (70.9%) were returned. The prevalence of HIV infection decreased from 21% in 1999 to 8.5% in 2009, HCV prevalence from 40% to 26.1% (p0.01), finding no significant differences in the prevalence of HBsAg +. Most of the inmates and civil servants believe that the program did not increase intravenous drug use and improves hygienic living conditions in prison.After ten years of development of the NEP, there was a significant decrease in the prevalence of HIV and HCV in the prison population at the centre, and the program is accepted as beneficial by most of the inmates and staff participating in the survey.

The magnitude and duration of dopamine (DA) signaling is defined by the amount of vesicular release, DA receptor sensitivity, and the efficiency of DA clearance, which is largely determined by the DA transporter (DAT). DAT uptake capacity is determined by the number of functional transporters on the cell surface as well as by their turnover rate. Here we show that inhibition of phosphatidylinositol (PI) 3-kinase with LY294002 induces internalization of the human DAT (hDAT), thereby reducing transport capacity. Acute treatment with LY294002 reduced the maximal rate of [(3) H]DA uptake in rat striatal synaptosomes and in human embryonic kidney (HEK) 293 cells stably expressing the hDAT (hDAT cells). In addition, LY294002 caused a significant redistribution of the hDAT from the plasma membrane to the cytosol. Conversely, insulin, which activates PI 3-kinase, increased [(3)H]DA uptake and blocked the amphetamine-induced hDAT intracellular accumulation, as did transient expression of constitutively active PI 3-kinase. The LY294002-induced reduction in [(3)H]DA uptake and hDAT cell surface expression was inhibited by expression of a dominant negative mutant of dynamin I, indicating that dynamin-dependent trafficking can modulate transport capacity. These data implicate DAT trafficking in the hormonal regulation of dopaminergic signaling, and suggest that a state of chronic hypoinsulinemia, such as in diabetes, may alter synaptic DA signaling by reducing the available cell surface DATs.

Increasingly growing evidence exists of the involvement of oxidative stress mechanisms in Parkinson's disease. Lower levels of GSH in the sustantia nigra, an increase in iron buildup, an increase in the byproducts of lipid peroxidation and alterations in the mitochondrial complex I have been described. However, few studies have been made of levels of antioxidants in the peripheral bloodstream and of the influence of the intake of nutrients on the development of this disease.In a group of 79 patients afflicted with idiopathic Parkinson's disease and a control group comprised of 107 subjects, compared by age, sex and place of residence, the lowered levels in the plasma of glutathione (GSH), malon dialdehyde (MDA), uric acid, tocophenol, beta-carotene, lycopene and different iron metabolism parameters were studied. Likewise, the intake of certain antioxidants was estimated based on a dietary survey.Significant differences (por = 0.001) were found in the plasma levels of GSH between cases (0.10 mumol/ml +/- 0.06) and controls (0.29 mumol/ml +/- 0.12). Likewise, the plasma levels of uric acid were lower (por = 0.05) in the cases (4.96 mg/ml +/- 1.96) than in the control groups (5.39 mg/ml +/- 1.13). No significant difference was found in the plasma levels of MDA, tocopherol, beta-carotene and lycopene. With regard to iron metabolism, significantly higher ferritine and transferrin values were found in the patients with EP than in the control group, showing a lower transferrin saturation percentage (por = 0.05). The iron showed no significant changes between cases and control groups.The results of this study support the possible involvement of oxidative stress in the pathogenesis of Parkinson's disease and reveal, in turn, alterations in some peripheral blood parameters in keeping with known findings in the sustantia nigra.

This study focuses on the comorbidity between medical and psychiatric illnesses in a sample taken from the general population.We design a two-stage epidemiological community study in the island of Formentera (Spain), using the Schedules for Clinical Assessment in Neuropsychiatry (SCAN). In the first stage, the sample (N=697) was screened using the General Health Questionnaire (GHQ-28). In the second stage, the SCAN, subjects' clinical histories and General Practitioners' diagnosis were used to evaluate psychiatric disorders and medical illnesses. The final sample comprised 242 subjects.Subjects with diagnosed ICD-10 mental disorders presented higher comorbidity with medical pathologies than the group of respondents without psychiatric diagnosis, although the differences were not statistically significant. Of the psychiatric conditions, mood disorders (in which differences were significant) and neurotic disorders were the ones that most frequently presented comorbidity, followed by sleep disorders. Mean scores on the GHQ-28 used at the screening stage, and mean scores on neurotic, depressive and somatic symptoms on the SCAN, were significantly higher in the comorbid group. Comorbidity was more frequent in females.More studies on comorbidity in general population are required, with diagnostic instruments that cover the whole of the psychiatric spectrum and correct assessment systems for medical diagnosis.

Smoking is the main single avoidable cause of death in our country. Little research in the treatment of such disorder has been made.To report the results of a prospective follow up for one year of outpatients from our "Smoker's Clinic" at the Department of Psychiatry of the Catholic University.One hundred twenty-seven patients (84 male, aged 21 to 70 years old), with DSM-IV criteria for nicotine dependence, were included in a total of 18 groups. Each group received an intensive treatment program of 10 sessions with cognitive-behavioral relapse prevention techniques and nicotine replacement. Patients with active psychiatric diseases were not included in the program.Eighty-seven percent of subjects were abstinent at the first month and 50% were still abstinent after twelve months of follow up. We did not find differences in gender, age, previous psychiatric disease, number of cigarettes and breath carbon monoxide level between abstinent and non abstinent patients after 12 months of follow up.This intensive nicotine dependence treatment in seriously dependent patients, proved to be successful, regardless of the previous psychiatric history.

The purpose of the study was to register antibody prevalences of HHV-7 in various locations of the world in comparison to the closely related HHV-6.Sera of healthy blood donors from nine countries in five continents were titered by indirect immunofluorescent assays using HHV-6 infected HSB2 and HHV-7 infected SupT1 cells.Antibody prevalence for HHV-7 is high (75-98%) in practically all countries except for Northern Japan (44%), with no simple correlation to elevated HHV-6 antibody titers. There were regions of low, intermediate and high mean antibody titers against HHV-7 such as 78.5-91.3 for Belgium, Israel, Japan, USA and Australia, 175.4-182.6 for Mexico and Cologne/Germany, and 389.2 for South Africa for which geographic characteristics may be responsible.HHV-7, similar to HHV-6, is a widespread human herpesvirus with elevated antibody titers in the healthy human population essentially everywhere. The data warrant further studies to evaluate its possible pathologic potential, preferentially in persons with defective immune responses.

Spanish prisons have a high number of inmates whose behaviour puts them at risk of being infected by hepatitis C virus (HCV). The object of this study was to establish the prevalence of this infection and its associated factors in the prison population of the north-east of Spain.Inmates in seven prisons in the north-east of Spain were studied. Socio-demographic and prison variables were gathered, as well as risk factors for infection by HCV. Antibodies against HCV were determined (EIA and INNO-LIA HCV III), Hepatitis B virus (VHB) (EIA), and human immunodeficiency virus (HIV) (EIA and Western-Blott). The analysis of associated factors was based on logistic regression.Of the total number of inmates studied, 47.9% presented HCV antibodies. There was greater prevalence in the case of the following: UDVP (89.6%); those who shared needles (94%); those infected by HIV (92.7%); carriers of Australia antigen (65.1%) and antibodies to the HBV core antigen (79.8%); those who had been in prison before (60.9%); unmarried men (54.8%); gypsies (52%); unqualified workers (50.4%); those who had no basic school qualifications (50.9%); those with tattoos (66.7%); and those with a background of self-inflicted injuries (79.3%). In the logistic regression analysis the variables associated to infection by HCV were: UDVP (OR = 33.3; I.C. 95% = 25-50), HBcAc (+) (OR = 4.1; I.C. 95% = 1.1-5.3), age (OR = 0.98; I.C. 95% = 0.96-1.00), months in prison (OR = 1.011; I.C. 95% = 1.004-1.019) and a background of previous prison sentences (OR = 2.3; I.C. 95% = 1.5-3.6).The prevalence of infection by HCV in prison inmates is very high. It is therefore recommended that preventive measures be increased (harm reduction programmes) and that clinical and analysis protocols be drawn up for those infected and for treatment in cases of chronic active hepatitis in order to control this serious public health problem.

The effect of several aliphatic aldehydes on lipid peroxidation was evaluated by measuring the oxygen uptake rate, thiobarbituric acid-reactive products formation and the emitted visible chemiluminescence intensity. Measurements were carried out in brain homogenates and erythrocyte plasma membrane and liver microsomal fractions. In all systems studied, aldehydes (25 mmol/L) (e.g. acetaldehyde, 2,2-dimethylpropanal), increased the intensity of the luminescence associated with the oxidation process. In contrast, aldehyde incorporation decreased TBARS production and the rate of oxygen uptake. The increased luminescence intensity is explained in terms of secondary reactions of aldehyde derived free radicals. These results clearly indicate that extreme care must be exercised in the interpretation of chemiluminescence data in the presence of aldehydes.

A patient with a remitting non-microcytic pulmonary carcinoma was subjected to Doppler-echocardiography. The detection of a pericardial effusion with compression of the pulmonary artery due to an extrinsic mass indicated that the disease was progressing. The Doppler technique was used to evaluate the degree of arterial stenosis by determining the pressure gradient caused by it (49 mmHg) and to calculate the right ventricle pressure (75 mmHg). Tumor infiltration of mediastinal structures was posteriorly confirmed by computed tomography.

The effect of age on the glutathione antioxidant system and its acinar distribution in rat liver was studied. GSH/GSSG ratio in blood and liver was lower in old than in young rats. Hepatic glutathione peroxidase and glutathione S-transferase activities were higher in old than in young rats, whereas hepatic gamma-glutamyl transpeptidase activity was lower in old than in young rats. Glutathione reductase and glucose-6-phosphate dehydrogenase activities did not change with age in rat liver. Total glutathione levels and glutathione peroxidase activity were higher in periportal than in perivenous areas of young rats, but this heterogeneous distribution did not occur in old rats. No change with age was found in hepatic zonation of glutathione reductase and glucose-6-phosphate dehydrogenase.

The dopamine transporter (DAT) regulates the clearance of dopamine (DA) released into the extracellular space and is an important site on which psychostimulants act to produce their effects. Here, we show that mitogen-activated protein kinase (MAPK) regulates the transport capacity and intracellular trafficking of DAT. Incubation of striatal synaptosomes or epitope-tagged human DAT (hDAT) human embryonic kidney (HEK) 293 cells with the MAPK kinase (MEK) inhibitors 1,4-diamino-2,3-dicyano-1,4-bis(o-aminophenylmercapto) butadiene and 2-(2-amino-3-methoxyphenyl)-4H-1-benzopyran-4-one decreased DA uptake in a concentration- and time-dependent manner. Kinetic studies revealed a decrease in the capacity of transport (Vmax) but no change inKm. Immunoblotting confirmed labeling of p42 and p44 MAPK in untreated striatal synaptosomes and HEK 293 cells, consistent with constitutive MAPK activation, and the inhibitors used decreased MAPK phosphorylation. Biotinylation and confocal imaging studies showed that MAPK inhibition promoted the clathrin-associated redistribution of hDAT from the plasma membrane to the cytosol. In contrast, transient transfection of hDAT-expressing cells with constitutively active MEK increased theVmaxof DA transport without alteringKm. However, only a small increase in hDAT cell surface expression was seen. These data demonstrate an involvement of the MAPK cascade in regulating DAT transport capacity in striatum and that inhibition of this cascade decreases DAT cell surface expression in HEK 293 cells. Furthermore, they highlight the potential role of MAPK as a presynaptic mechanism that regulates DA signaling.
