Effectiveness of brief alcohol interventions in primary care populations.

Excessive drinking contributes significantly to social problems, physical and psychological illness, injury and death. Hidden effects include increased levels of violence, accidents and suicide. Most alcohol-related harm is caused by excessive drinkers whose consumption exceeds recommended drinking levels, not the drinkers with severe alcohol dependency problems. One way to reduce consumption levels in a community may be to provide a brief intervention in primary care over one to four sessions. This is provided by healthcare workers such as general physicians, nurses or psychologists. In general practice, patients are routinely asked about alcohol consumption during registration, general health checks and as part of health screening (using a questionnaire). They tend not to be seeking help for alcohol problems when presenting. The intervention they are offered includes feedback on alcohol use and harms, identification of high risk situations for drinking and coping strategies, increased motivation and the development of a personal plan to reduce drinking. It takes place within the time-frame of a standard consultation, 5 to 15 minutes for a general physician, longer for a nurse.A total of 29 controlled trials from various countries were identified, in general practice (24 trials) or an emergency setting (five trials). Participants drank an average of 306 grams of alcohol (over 30 standard drinks) per week on entry to the trial. Over 7000 participants with a mean age of 43 years were randomised to receive a brief intervention or a control intervention, including assessment only. After one year or more, people who received the brief intervention drank less alcohol than people in the control group (average difference 38 grams/week, range 23 to 54 grams). For men (some 70% of participants), the benefit of brief intervention was a difference of 57 grams/week, range 25 to 89 grams (six trials). The benefit was not clear for women. The benefits of brief intervention were similar in the normal clinical setting and in research settings with greater resources. Longer counselling had little additional benefit.This resource was contributed by The National Documentation Centre on Drug Use.

The meaning of dependence and independence of older people with a disability in Ireland

The paper presents the findings of a research study carried out in Ireland in 2006 (Murphy et al., 2007) which explored the meaning of dependence and independence for older people with a disability. The research adopted a grounded theory approach; purposive sampling was used initially with some relational sampling towards the latter interviews. The sample was comprised of 143 older people with one of six disabilities: stroke (n=20), arthritis (20), depression (20), sensory disability (20), a learning disability (24), and dementia (18). All participants lived at home, some participants required high levels of help in activities of living while others were mostly independent. An interview schedule was used to guide interviews, all of which were tape recorded and transcribed. Data was collected on levels of dependence and independence using the Katz scale. Participants recorded high levels of independence in relation to transferring (93%), toileting (92%), dressing (87%), continence (87%) and feeding (98%). The main area of dependence where participants required assistance from others was with bathing (77%). The constant comparative technique was used to analyze qualitative data. The findings of the study would suggest that participants personal definition of their independence or dependence shifted relative to others and/or improvement or worsening of their capacity People were aware of the difference between independence and dependence, but these two concepts were not always perceived as opposites. It was possible to be independent and dependent at the same time. People valued being able to do things for themselves, accepted help when necessary but wanted to reciprocate when possible. Participants used varied coping strategies to regain and retain control of their lives. Strategies to promote older peoples independence and self esteem will be explored in this paper.

An international, randomized, double-blind, placebo-controlled, phase III trial of pregabalin monotherapy in treatment of patients with fibromyalgia.

OBJECTIVE: To evaluate the efficacy and safety of pregabalin monotherapy versus placebo for symptomatic pain relief and improvement of patient global assessment in patients with fibromyalgia (FM) enrolled from countries outside the United States. METHODS: This international, multicenter, double-blind, placebo-controlled trial randomly assigned 747 patients with FM to placebo or 300, 450, or 600 mg/day pregabalin twice daily for 14 weeks. Primary efficacy measures were endpoint mean pain scores and Patient Global Impression of Change (PGIC). Secondary outcomes included assessments of sleep and function. RESULTS: Patients in the 450 mg/day pregabalin group showed significant improvements versus placebo in endpoint mean pain score (-0.56; p = 0.0132), PGIC (73% improved vs 56% placebo; p = 0.0017), and function [Fibromyalgia Impact Questionnaire (FIQ) total score -5.85; p = 0.0012]. PGIC was also significant for 600 mg/day pregabalin (69% improved; p = 0.0227). Results for these endpoints were nonsignificant for pregabalin at 300 mg/day and for pain and FIQ score at 600 mg/day. Early onset of pain relief was seen, with separation from placebo detected by Week 1 in all pregabalin groups. All pregabalin doses demonstrated superiority to placebo on the Medical Outcomes Study-Sleep Scale Sleep Disturbance subscale and the Sleep Quality diary. Dizziness and somnolence were the most frequently reported adverse events. CONCLUSION: Pregabalin demonstrated modest efficacy in pain, global assessment, and function in FM at 450 mg/day, and improved sleep across all dose levels, but it did not provide consistent evidence of benefit at 300 and 600 mg/day in this study. Pregabalin was generally well tolerated for the treatment of FM. (Clinical trial registry NCT00333866).

Peer pressure and alcohol use in young men: a mediation analysis of drinking motives.

BACKGROUND: Peer pressure (PP) has been shown to play a major role in the development and continuation of alcohol use and misuse. To date, almost all the studies investigating the association of PP with alcohol use only considered the PP for misconduct but largely ignored other aspects of PP, such as pressure for peer involvement and peer conformity. Moreover, it is not clear whether the association of PP with alcohol use is direct or mediated by other factors. The aim of the present study was to investigate the association of different aspects of peer pressure (PP) with drinking volume (DV) and risky single-occasion drinking (RSOD), and to explore whether these associations were mediated by drinking motives (DM). METHODS: A representative sample of 5521 young Swiss men, aged around 20 years old, completed a questionnaire assessing their usual weekly DV, the frequency of RSOD, DM (i.e. enhancement, social, coping, and conformity motives), and 3 aspects of PP (i.e. misconduct, peer involvement, and peer conformity). Associations between PP and alcohol outcomes (DV and RSOD) as well as the mediation of DM were tested using structural equation models. RESULTS: Peer pressure to misconduct was associated with more alcohol use, whereas peer involvement and peer conformity were associated with less alcohol use. Associations of drinking outcomes with PP to misconduct and peer involvement were partially mediated by enhancement and coping motives, while the association with peer conformity was partially mediated by enhancement and conformity motives. CONCLUSIONS: Results suggest that PP to misconduct constitutes a risk factor, while peer conformity and peer involvement reflect protective factors with regard to alcohol use. Moreover, results from the mediation analyses suggest that part of the association of PP with alcohol use came indirectly through DM: PP was associated with DM, which in turn were associated with alcohol use.

La conversion religieuse: un processus créatif

Les récits de conversion religieuse présentent plusieurs traits communs avec les récits de découvertes scientifiques (Aha-Erlebnisse, expériences de eurêka): événement instantané, exceptionnel, inattendu, marquant une rupture par rapport au passé. Or, il s'agit dans les deux cas de reconstructions a posteriori qui ont tendance à survaloriser le caractère instantané d'un événement au détriment du processus organisant la mise en place d'une nouvelle vision du monde. Howard Gruber l'a très bien montré dans son étude consacrée à Charles Darwin. Là où le récit autobiographique, formulé une quarantaine d'années après l'énoncé de la théorie de la sélection naturelle, donne l'impression d'une intuition subite, les carnets de notes, rédigés à l'époque où s'élabore la théorie, permettent de mettre en évidence un processus créatif qui s'étale sur près d'un an et demi. Ce constat peut être étendu aux récits de conversion religieuse. Le cas de Martin Luther en est une excellente illustration. Ce parallèle entre découverte scientifique et conversion religieuse jette un éclairage nouveau sur cette dernière: l'événement inattendu où tout bascule doit être articulé avec un processus psychologique qui le porte et même le décompose sur une durée bien plus longue que ce que la mémoire ne le reconstruit après-coup. Au point qu'il n'est pas exagéré de voir dans le récit d'une conversion religieuse, ne serait-ce que pour une part, l'expression de la créativité d'un sujet qui invente une solution au problème de sa vie.

Implications of Objective vs Subjective Delirium Assessment in Surgical Intensive Care Patients.

Background Delirium is an independent predictor of increased length of stay, mortality, and treatment costs in critical care patients. Its incidence may be underestimated or overestimated if delirium is assessed by using subjective clinical impression alone rather than an objective instrument. Objectives To determine frequency of discrepancies between subjective and objective delirium monitoring. Methods An observational cohort study was performed in a surgical-cardiosurgical 31-bed intensive care unit of a university hospital. Patients' delirium status was rated daily by bedside nurses on the basis of subjective individual clinical impressions and by medical students on the basis of scores on the objective Confusion Assessment Method for the Intensive Care Unit. Results Of 160 patients suitable for analysis, 38.8% (n = 62) had delirium according to objective criteria at some time during their stay in the intensive care unit. A total of 436 paired observations were analyzed. Delirium was diagnosed in 26.1% of observations (n = 114) with the objective method. This percentage included 6.4% (n = 28) in whom delirium was not recognized via subjective criteria. According to subjective criteria, delirium was present in 29.4% of paired observations (n = 128), including 9.6% (n = 42) with no objective indications of delirium. A total of 8 patients with no evidence of delirium according to the objective criteria were prescribed haloperidol and lorazepam because the subjective method indicated they had delirium. Conclusions Use of objective criteria helped detect delirium in more patients and also identified patients mistakenly thought to have delirium who actually did not meet objective criteria for diagnosis of the condition.

Theileria electrophorin.sp., a parasite of the electric eel Electrophorus electricus (Osteichthyes: Cypriniformes: Gymnotidae) from Amazonian Brazil

The name Theileria electrophori n.sp. is proposed for a small parasite described in the erythrocytes of the electric eel, Electrophorus electricus, from Amazonian Brazil. Division of the organism in the erythrocyte produces only four bacilliform daughter cells which become scattered in the host cell, without a cruciform or rosette-shaped disposition. Exoerythrocytic meronts producing a large number of merozoites were encountered in Giemsa-stained impression smears of the internal organs, principally in the liver, and are presumably the source of the intraerythrocytic forms of the parasite. This developmental pattern is characteristic of piroplasms within the family Theileriidae, where the author considers the parasite of E. electricus to most appropriately belong. It effectively distinguishes the organism from the dactylosomatid parasites Babesiosoma Jakowska and Nigrelli, 1956 and Dactylosoma Labbé, 1894 also found in fishes. This appears to be the second report of Theileria Bettencourt, Franca and Borges, 1907 in a fish.

Instruments measuring spirituality in clinical research: a systematic review.

INTRODUCTION: Numerous instruments have been developed to assess spirituality and measure its association with health outcomes. This study's aims were to identify instruments used in clinical research that measure spirituality; to propose a classification of these instruments; and to identify those instruments that could provide information on the need for spiritual intervention. METHODS: A systematic literature search in MEDLINE, CINHAL, PsycINFO, ATLA, and EMBASE databases, using the terms "spirituality" and "adult$," and limited to journal articles was performed to identify clinical studies that used a spiritual assessment instrument. For each instrument identified, measured constructs, intended goals, and data on psychometric properties were retrieved. A conceptual and a functional classification of instruments were developed. RESULTS: Thirty-five instruments were retrieved and classified into measures of general spirituality (N = 22), spiritual well-being (N = 5), spiritual coping (N = 4), and spiritual needs (N = 4) according to the conceptual classification. Instruments most frequently used in clinical research were the FACIT-Sp and the Spiritual Well-Being Scale. Data on psychometric properties were mostly limited to content validity and inter-item reliability. According to the functional classification, 16 instruments were identified that included at least one item measuring a current spiritual state, but only three of those appeared suitable to address the need for spiritual intervention. CONCLUSIONS: Instruments identified in this systematic review assess multiple dimensions of spirituality, and the proposed classifications should help clinical researchers interested in investigating the complex relationship between spirituality and health. Findings underscore the scarcity of instruments specifically designed to measure a patient's current spiritual state. Moreover, the relatively limited data available on psychometric properties of these instruments highlight the need for additional research to determine whether they are suitable in identifying the need for spiritual interventions.

The association between drinking motives and alcohol-related consequences - room for biases and measurement issues?

Aims  To investigate whether the predominant finding of generalized positive associations between self-rated motives for drinking alcohol and negative consequences of drinking alcohol are influenced by (i) using raw scores of motives that may weight inter-individual response behaviours too strongly, and (ii) predictor-criterion contamination by using consequence items where respondents attribute alcohol use as the cause. Design  Cross-sectional study within the European School Survey Project on Alcohol and other Drugs (ESPAD). Setting  School classes. Participants  Students, aged 13-16 (n = 5633). Measurements  Raw, rank and mean-variance standardized scores of the Drinking Motives Questionnaire-Revised (DMQ-R); four consequences: serious problems with friends, sexual intercourse regretted the next day, physical fights and troubles with the police, each itemized with attribution ('because of your alcohol use') and without. Findings  As found previously in the literature, raw scores for all drinking motives had positive associations with negative consequences of drinking, while transformed (rank or Z) scores showed a more specific pattern: external reinforcing motives (social, conformity) had negative and internal reinforcing motives (enhancement, coping) had non-significant or positive associations with negative consequences. Attributed consequences showed stronger associations with motives than non-attributed ones. Conclusion  Standard scoring of the Drinking Motives Questionnaire (Revised) fails to capture motives in a way that permits specific associations with different negative consequences to be identified, whereas use of rank or Z-scores does permit this. Use of attributed consequences overestimates the association with drinking motives.

Development and experimental validation of a finite element model of total ankle replacement.

Total ankle replacement remains a less satisfactory solution compared to other joint replacements. The goal of this study was to develop and validate a finite element model of total ankle replacement, for future testing of hypotheses related to clinical issues. To validate the finite element model, an experimental setup was specifically developed and applied on 8 cadaveric tibias. A non-cemented press fit tibial component of a mobile bearing prosthesis was inserted into the tibias. Two extreme anterior and posterior positions of the mobile bearing insert were considered, as well as a centered one. An axial force of 2kN was applied for each insert position. Strains were measured on the bone surface using digital image correlation. Tibias were CT scanned before implantation, after implantation, and after mechanical tests and removal of the prosthesis. The finite element model replicated the experimental setup. The first CT was used to build the geometry and evaluate the mechanical properties of the tibias. The second CT was used to set the implant position. The third CT was used to assess the bone-implant interface conditions. The coefficient of determination (R-squared) between the measured and predicted strains was 0.91. Predicted bone strains were maximal around the implant keel, especially at the anterior and posterior ends. The finite element model presented here is validated for future tests using more physiological loading conditions.

Effectiveness of a nurse-led case management home care model in Primary Health Care. A quasi-experimental, controlled, multi-centre study

Background Demand for home care services has increased considerably, along with the growing complexity of cases and variability among resources and providers. Designing services that guarantee co-ordination and integration for providers and levels of care is of paramount importance. The aim of this study is to determine the effectiveness of a new case-management based, home care delivery model which has been implemented in Andalusia (Spain). Methods Quasi-experimental, controlled, non-randomised, multi-centre study on the population receiving home care services comparing the outcomes of the new model, which included nurse-led case management, versus the conventional one. Primary endpoints: functional status, satisfaction and use of healthcare resources. Secondary endpoints: recruitment and caregiver burden, mortality, institutionalisation, quality of life and family function. Analyses were performed at base-line, and at two, six and twelve months. A bivariate analysis was conducted with the Student's t-test, Mann-Whitney's U, and the chi squared test. Kaplan-Meier and log-rank tests were performed to compare survival and institutionalisation. A multivariate analysis was performed to pinpoint factors that impact on improvement of functional ability. Results Base-line differences in functional capacity – significantly lower in the intervention group (RR: 1.52 95%CI: 1.05–2.21; p = 0.0016) – disappeared at six months (RR: 1.31 95%CI: 0.87–1.98; p = 0.178). At six months, caregiver burden showed a slight reduction in the intervention group, whereas it increased notably in the control group (base-line Zarit Test: 57.06 95%CI: 54.77–59.34 vs. 60.50 95%CI: 53.63–67.37; p = 0.264), (Zarit Test at six months: 53.79 95%CI: 49.67–57.92 vs. 66.26 95%CI: 60.66–71.86 p = 0.002). Patients in the intervention group received more physiotherapy (7.92 CI95%: 5.22–10.62 vs. 3.24 95%CI: 1.37–5.310; p = 0.0001) and, on average, required fewer home care visits (9.40 95%CI: 7.89–10.92 vs.11.30 95%CI: 9.10–14.54). No differences were found in terms of frequency of visits to A&E or hospital re-admissions. Furthermore, patients in the control group perceived higher levels of satisfaction (16.88; 95%CI: 16.32–17.43; range: 0–21, vs. 14.65 95%CI: 13.61–15.68; p = 0,001). Conclusion A home care service model that includes nurse-led case management streamlines access to healthcare services and resources, while impacting positively on patients' functional ability and caregiver burden, with increased levels of satisfaction.

Depression with atypical features and increase in obesity, body mass index, waist circumference, and fat mass: a prospective, population-based study.

IMPORTANCE: Depression and obesity are 2 prevalent disorders that have been repeatedly shown to be associated. However, the mechanisms and temporal sequence underlying this association are poorly understood. OBJECTIVE: To determine whether the subtypes of major depressive disorder (MDD; melancholic, atypical, combined, or unspecified) are predictive of adiposity in terms of the incidence of obesity and changes in body mass index (calculated as weight in kilograms divided by height in meters squared), waist circumference, and fat mass. DESIGN, SETTING, AND PARTICIPANTS: This prospective population-based cohort study, CoLaus (Cohorte Lausannoise)/PsyCoLaus (Psychiatric arm of the CoLaus Study), with 5.5 years of follow-up included 3054 randomly selected residents (mean age, 49.7 years; 53.1% were women) of the city of Lausanne, Switzerland (according to the civil register), aged 35 to 66 years in 2003, who accepted the physical and psychiatric baseline and physical follow-up evaluations. EXPOSURES: Depression subtypes according to the DSM-IV. Diagnostic criteria at baseline and follow-up, as well as sociodemographic characteristics, lifestyle (alcohol and tobacco use and physical activity), and medication, were elicited using the semistructured Diagnostic Interview for Genetic Studies. MAIN OUTCOMES AND MEASURES: Changes in body mass index, waist circumference, and fat mass during the follow-up period, in percentage of the baseline value, and the incidence of obesity during the follow-up period among nonobese participants at baseline. Weight, height, waist circumference, and body fat (bioimpedance) were measured at baseline and follow-up by trained field interviewers. RESULTS: Only participants with the atypical subtype of MDD at baseline revealed a higher increase in adiposity during follow-up than participants without MDD. The associations between this MDD subtype and body mass index (β = 3.19; 95% CI, 1.50-4.88), incidence of obesity (odds ratio, 3.75; 95% CI, 1.24-11.35), waist circumference in both sexes (β = 2.44; 95% CI, 0.21-4.66), and fat mass in men (β = 16.36; 95% CI, 4.81-27.92) remained significant after adjustments for a wide range of possible cofounding. CONCLUSIONS AND RELEVANCE: The atypical subtype of MDD is a strong predictor of obesity. This emphasizes the need to identify individuals with this subtype of MDD in both clinical and research settings. Therapeutic measures to diminish the consequences of increased appetite during depressive episodes with atypical features are advocated.

Apoyo social a drogodependientes en programa de mantenimiento con metadona en una prisión

Goal: To learn more about the social support available to patients participating in a prison methadone maintenance program (PMM). Methodology: Descriptive, with controls. Setting: A penitentiary in Albolote (Granada) Population Sample: The total prison population was 1,579; 364 patients were included in the PMM; 35 were female and 329 were male. 60 patients, 7 women and 53 men, were used as cases. 30 non-drug dependent prisoners, 3 women and 27 men, were the control group. They had no antecedents of problems with drug addiction. Interventions: Interviews with cases and controls to learn about their addictive antecedents, family structure, socio-economic level, and a hetero-applied MOS questionnaire was completed. Percentages of each social support variable were obtained and compared using the chi-squared technique. Results: The overall support received is low in 38 cases (74.5%) and in 9 controls (30%): p = 0.0001. OR 0.1466, confidence interval at 95% (0.0538-0.3989). Support received is normal in 13 cases (25%) and 21 controls (70%): p = 0.0007. OR 0.69, confidence interval at 95% (0.44-0.93). All of the variables were statistically significant for non-drug addicts, except for emotional support, which was the same for both groups. Conclusion: The perception of inmates participating in the methadone maintenance program was that they received less social support than the non-drug dependent inmates.
