FIVE-FACTOR MODEL PERSONALITY PROFILES: THE DIFFERENCES BETWEEN ALCOHOL AND OPIATE ADDICTION AMONG FEMALES

Background: The prevalence of female alcohol and substance abusers has markedly increased. The main objective of this research was to explore personality profiles among females who had alcohol and opiate dependence. Aim: The aim of the study is to analyse if there is differences in personality profiles of females addicted to alcohol and opiates. We hypothesized that there might be significant differences in personality profiles among subgroups of women who present with alcohol and opiate use disorders. Subjects and methods: Of 157 consecutive women with diagnosis of alcohol/opiate addiction, 62 fulfilled following inclusion criteria: age 19-45 years, abstinence from alcohol and opiates for at least 10 days prior to enrollment. Alcohol-dependent group consisted of 30 females, while opiate-dependent group consisted of 32 females. The control group involved 30 age-matched randomly chosen healthy women. The data were collected using the Revised NEO Personality Inventory (NEO-PI-R). The multiple stepwise discriminant analysis was used to determine relations between personality traits and the probability of belonging to one of the study groups. Results: Significant differences in the NEO-PI-R scores were observed between groups for all main personality traits except for Openness to Experience. Compared with controls, substance-dependent women scored significantly higher on Neuroticism and lower on Conscientiousness. Opiate-dependent females scored the highest on Neuroticism and on Extraversion and lowest on Agreeableness and on Conscientiousness. Alcohol-dependent females scored higher on Conscientiousness and lower on Neuroticism compared to opiate-dependent women. Conclusions: The results of our study confirmed significant characteristics in personality profiles among females with alcohol and opiate dependence, as well as the difference between these two groups of substance abusers and their healthy controls. The distinct personality characteristics among different groups of substance addicted women should be taken into account when creating the most effective program of prevention and therapeutic approaches in this specific cohort

The direction of research into visual disability and quality of life in glaucoma

<p>Abstract</p> <p>Background</p> <p>Glaucoma will undoubtedly impact on a person's ability to function as they go about their day-to-day life. The purpose of this study is to investigate the amount of published knowledge in quality of life (QoL) and visual disability studies for glaucoma, and make comparisons with similar research in other chronic conditions.</p> <p>Methods</p> <p>A systematic literature search of the Global Health, EMBASE Psychiatry and MEDLINE databases. Title searches for glaucoma and six other example chronic diseases were entered alongside a selection of keywords chosen to capture studies focusing on QoL and everyday task ability. These results were further filtered during a manual search of resulting abstracts. Outcomes were the number of publications per year for each disease, number relating to QoL and type of glaucoma QoL research.</p> <p>Results</p> <p>Fifteen years ago there were no published studies relating to the impact of glaucoma on QoL but by 2009 this had risen to 1.2% of all glaucoma articles. The number of papers relating to QoL as a proportion of all papers in glaucoma in the past 10 years (0.6%) is smaller than for AMD and some other disabling chronic diseases. Most QoL studies in glaucoma (82%) involve questionnaires.</p> <p>Conclusion</p> <p>QoL studies in glaucoma are increasing in number but represent a tiny minority of the total publications in glaucoma research. There are fewer QoL articles in glaucoma compared to some other disabling chronic conditions. The majority of QoL articles in glaucoma research use questionnaires; performance-based measures of visual disability may offer an additional method of determining how the disease impacts on QoL.</p

Cation insertion to break the activity/stability relationship for highly active oxygen evolution reaction catalyst

The production of hydrogen at a large scale by the environmentally-friendly electrolysis process is currently hampered by the slow kinetics of the oxygen evolution reaction (OER). We report a solid electrocatalyst α-Li2IrO3 which upon oxidation/delithiation chemically reacts with water to form a hydrated birnessite phase, the OER activity of which is five times greater than its non-reacted counterpart. This reaction enlists a bulk redox process during which hydrated potassium ions from the alkaline electrolyte are inserted into the structure while water is oxidized and oxygen evolved. This singular charge balance process for which the electrocatalyst is solid but the reaction is homogeneous in nature allows stabilizing the surface of the catalyst while ensuring stable OER performances, thus breaking the activity/stability tradeoff normally encountered for OER catalysts

Psychological factors as predictors of early postoperative pain after open nephrectomy

Purpose: There is an increasing interest in the identification of predictors for individual responses to analgesics and surgical pain. In this study, we aimed to determine psychological factors that might contribute to this response. We hence investigated patients undergoing a standardized surgical intervention (open nephrectomy). Patients and methods: Between May 2014 and April 2015, we conducted a prospective observational cohort study. The following psychological tests were administered preoperatively: Mini-Mental State Examination, Amsterdam Preoperative Anxiety and Information Scale (APAIS), Hamilton Anxiety Rating Scale, Hamilton Depression Rating Scale, and Pain Catastrophizing Scale. The primary outcome, postoperative pain intensity (11-point numerical rating scale, [NRS]), was assessed in the “immediate early” (first 8 hours), “early” (12 and 24 hours), and “late early” periods (48 and 72 hours). Results: A total of 196 patients were assessed, and 150 were finally included in the study. NRS scores improved from 4.9 (95% confidence interval [CI]: 4.7–5.1) in the “immediate early” to 3.1 (95% CI: 2.9–3.3) in the “early” and 2.3 (95% CI: 2.1–2.5) in the “late early” postoperative period. Most (87%) patients received intravenous opioids, while 13% received analgesics epidurally. Repeated measures analysis of variance indicated better pain management with epidural analgesia in the first two postoperative periods (F=15.01, p<0.00). Postoperative pain correlated strongly with analgesic strategy and preoperative psychological assessment. Multiple linear regression analysis showed “expected pain” was the only predictor in the “immediate early” phase, and “anxiety” was most important in the “early” postoperative period. In the “late early” phase, catastrophizing was the predominant predictor, alongside “preoperative analgesic usage” and “APAIS anxiety”. Conclusion: After open nephrectomy, epidural analgesia conveys a clear advantage for pain management only within the first 24 hours. Moreover, as the psychological phenotype of patients changes distinctively in the first 72 postoperative hours, psychological variables increasingly determine pain intensity, even surpassing employed analgesic strategy as its main predictor

Are pediatricians responsible for maintaining high MMR vaccination coverage? Nationwide survey on parental knowledge and attitudes towards MMR vaccine in Serbia.

AimTo assess parental knowledge and attitudes related to MMR vaccination and to determine factors associated with parental decision whether to vaccinate their child with MMR vaccine in Serbian population.MethodsThe selection of participants was performed using multi-phase sampling. Seventeen out of the total 160 public health centers on the territory of Republic of Serbia were randomly selected. All parents of children up to the age of 7 who visited the pediatrician at the public health centers from June to August 2017 were recruited. Parents filled in an anonymous questionnaire regarding their knowledge, attitudes and practices in immunization with MMR vaccine. The relative contribution of different factors was explored by univariable and multivariable logistic regression analysis.ResultsThe majority of parents were female (75.2%), with mean age of 34.3 ± 5.7 years, and the average age of children was 4.7 ± 2.4 years, 53.7% of them were girls. In the multivariable model, getting information on vaccination from a pediatrician was associated with 7.5 fold increased probability to vaccinate child with MMR vaccine (OR = 7.52; 95% CI 2.73-20.74; pConclusionOur study emphasized the key role of pediatricians in the formation of parental attitude on MMR vaccination of their child

Cardiac Nitric Oxide Synthases and Na+/K+-ATPase in the Rat Model of Polycystic Ovary Syndrome Induced by Dihydrotestosterone

Nitric oxide synthases (NOSs) and Na+/K+-ATPase are enzymes essential for regular functioning of the heart. Since both enzymes are under insulin and androgen regulation and since insulin action and androgen level were disturbed in polycystic ovary syndrome (PCOS), we hypothesized that cardiac nitric oxide (NO) production and sodium/potassium transport would be deteriorated in PCOS. To test our hypothesis we introduced animal model of PCOS based on dihydrotestosterone (DHT) treatment of female Wistar rats and analyzed protein expression, phosphorylation or subcellular localization of endothelial NOS (eNOS), inducible NOS (iNOS) and alpha subunits of Na+/K+-ATPase in the heart. Obtained results indicate that DHT treatment significantly decreased cardiac eNOS protein level and activating phosphorylation at serine 1177, while inhibitory phosphorylation at threonine 495 was increased. In contrast to expression of eNOS, iNOS protein level in the heart of DHT-treated rats was significantly elevated. Furthermore, cardiac protein level of alpha 1 subunit of the ATPase, as well as its plasma membrane content, were decreased in rats with PCOS. In line with this, alpha 2 subunit protein level in fraction of plasma membranes was also significantly below control level. In conclusion, DHT treatment impaired effectiveness of NOSs and Na+/K+-ATPase in the female rat heart. Regarding the importance of NO production and sodium/potassium transport in the cardiac contraction and blood flow regulation, it implicates strong consequences of PCOS for heart functioning.Ministry of Education, Science and Technological Development, Republic of Serbia {[}III41009
