DSM-IV and DSM-5 alcohol use disorder among young Swiss men.

BACKGROUND AND AIMS: Previous studies suggest that the new DSM-5 criteria for alcohol use disorder (AUD) will increase the apparent prevalence of AUD. This study estimates the 12-month prevalence of AUD using both DSM-IV and DSM-5 criteria and compares the characteristics of men in a high risk sample who meet both, only one and neither sets of diagnostic criteria. DESIGN, SETTING AND PARTICIPANTS: 5943 Swiss men aged 18-25 years who participated in the Cohort Study on Substance Use Risk Factors (C-SURF), a population-based cohort study recruited from three of the six military recruitment centres in Switzerland (response rate = 79.2%). MEASUREMENTS: DSM-IV and DSM-5 criteria, alcohol use patterns, and other substance use were assessed. FINDINGS: Approximately 31.7% (30.5-32.8) of individuals met DSM-5 AUD criteria [21.2% mild (20.1-22.2); 10.5% moderate/severe (9.7-11.3)], which was less than the total rate when DSM-IV criteria for alcohol abuse (AA) and alcohol dependence (AD) were combined [36.8% overall (35.5-37.9); 26.6% AA (25.4-27.7); 10.2% AD (9.4-10.9)]. Of 2479 respondents meeting criteria for either diagnoses, 1585 (63.9%) met criteria for both. For those meeting DSM-IV criteria only (n = 598, 24.1%), hazardous use was most prevalent, whereas the criteria larger/longer use than intended and tolerance to alcohol were most prevalent for respondents meeting DSM-5 criteria only (n = 296, 11.9%). Two in five DSM-IV alcohol abuse cases and one-third of DSM-5 mild AUD individuals fulfilled the diagnostic criteria due to the hazardous use criterion. The addition of the craving and excluding of legal criterion, respectively, did not affect estimated AUD prevalence. CONCLUSIONS: In a high-risk sample of young Swiss males, prevalence of alcohol use disorder as diagnosed by DSM-5 was slightly lower than prevalence of DSM-IV diagnosis of dependence plus abuse; 63.9% of those who met either criterion met criteria for both.

Hospitalized women experiencing an episode of excessive oral anticoagulation had a higher bleeding risk than men.

OBJECTIVE: Overanticoagulated medical inpatients may be particularly prone to bleeding complications. Among medical inpatients with excessive oral anticoagulation (AC), we sought to identify patient and treatment factors associated with bleeding. METHODS: We prospectively identified consecutive patients receiving oral AC admitted to the medical ward of a university hospital (February-July 2006) who had at least one international normalized ratio (INR) value >3.0 during the hospital stay. We recorded patient characteristics, AC-related factors, and concomitant treatments (e.g., platelet inhibitors) that increase the bleeding risk. The outcome was overall bleeding, defined as the occurrence of major or minor bleeding during the hospital stay. We used logistic regression to explore patient and treatment factors associated with bleeding. RESULTS: Overall, 145 inpatients with excessive oral AC comprised our study sample. Atrial fibrillation (59%) and venous thromboembolism (28%) were the most common indications for AC. Twelve patients (8.3%) experienced a bleeding event. Of these, 8 had major bleeding. Women had a somewhat higher risk of major bleeding than men (12.5% vs 4.1%, p = 0.08). Multivariable analysis demonstrated that female gender was independently associated with bleeding (odds ratio [OR] 4.3, 95% confidence interval [95% C1] 1.1-17.8). Age, history of major bleeding, value of the index INR, and concomitant treatment with platelet inhibitors were not independent predictors of bleeding. CONCLUSIONS: We found that hospitalized women experiencing an episode of excessive oral AC have a 4-fold increased risk of bleeding compared with men. Whether overanticoagulated women require more aggressive measures of AC reversal must be examined in further studies.

Healthcare utilization of elderly persons hospitalized after a noninjurious fall in a Swiss academic medical center.

OBJECTIVES: To determine the risk of hospital readmission, nursing home admission, and death, as well as health services utilization over a 6-month follow-up, in community-dwelling elderly persons hospitalized after a noninjurious fall. DESIGN: Prospective cohort study with 6-month follow-up. SETTING: Swiss academic medical center. PARTICIPANTS: Six hundred ninety persons aged 75 and older hospitalized through the emergency department. MEASUREMENTS: Data on demographics and medical, physical, social, and mental status were collected upon admission. Follow-up data were collected from the state centralized billing system (hospital and nursing home admission) and proxies (death). RESULTS: Seventy patients (10%) were hospitalized after a noninjurious fall. Fallers had shorter hospital stays (median 4 vs 8 days, P<.001) and were more frequently discharged to rehabilitation or respite care than nonfallers. During follow-up, fallers were more likely to be institutionalized (adjusted hazard ratio=1.82, 95% confidence interval=1.03-3.19, P=.04) independent of comorbidity and functional and mental status. Overall institutional costs (averaged per day of follow-up) were similar for both groups ($138.5 vs $148.7, P=.66), but fallers had lower hospital costs and significantly higher rehabilitation and long-term care costs ($55.5 vs $24.1, P<.001), even after adjustment for comorbidity, living situation, and functional and cognitive status. CONCLUSION: Elderly patients hospitalized after a noninjurious fall were twice as likely to be institutionalized as those admitted for other medical conditions and had higher intermediate and long-term care services utilization during follow-up, independent of functional and health status. These results provide direction for interventions needed to delay or prevent institutionalization and reduce subsequent costs.

Long maximal incremental tests accurately assess aerobic fitness in class II and III obese men.

This study aimed to compare two different maximal incremental tests with different time durations [a maximal incremental ramp test with a short time duration (8-12 min) (STest) and a maximal incremental test with a longer time duration (20-25 min) (LTest)] to investigate whether an LTest accurately assesses aerobic fitness in class II and III obese men. Twenty obese men (BMI≥35 kg.m-2) without secondary pathologies (mean±SE; 36.7±1.9 yr; 41.8±0.7 kg*m-2) completed an STest (warm-up: 40 W; increment: 20 W*min-1) and an LTest [warm-up: 20% of the peak power output (PPO) reached during the STest; increment: 10% PPO every 5 min until 70% PPO was reached or until the respiratory exchange ratio reached 1.0, followed by 15 W.min-1 until exhaustion] on a cycle-ergometer to assess the peak oxygen uptake [Formula: see text] and peak heart rate (HRpeak) of each test. There were no significant differences in [Formula: see text] (STest: 3.1±0.1 L*min-1; LTest: 3.0±0.1 L*min-1) and HRpeak (STest: 174±4 bpm; LTest: 173±4 bpm) between the two tests. Bland-Altman plot analyses showed good agreement and Pearson product-moment and intra-class correlation coefficients showed a strong correlation between [Formula: see text] (r=0.81 for both; p≤0.001) and HRpeak (r=0.95 for both; p≤0.001) during both tests. [Formula: see text] and HRpeak assessments were not compromised by test duration in class II and III obese men. Therefore, we suggest that the LTest is a feasible test that accurately assesses aerobic fitness and may allow for the exercise intensity prescription and individualization that will lead to improved therapeutic approaches in treating obesity and severe obesity.

Postoperative Cognitive Dysfunction (POCD) and Inflammatory Markers in Elderly Patients

Introduction: Particularly in elderly patients, the brain responds to a systemic inflammatory response with an increased production of inflammatory mediators. This has hypothetically been linked to the development of postoperative cognitive dysfunction (POCD). Methods: We investigated 31 patients aged >65 yrs undergoing elective major surgery under standardized general anaesthesia (thiopental, sevoflurane, fentanyl, atracurium). Cognitive function was measured preoperatively and 7 days postoperatively using the extended version of the Consortium to Establish a Registry for Alzheimer's Disease - Neuropsychological Assessment Battery (CERAD-NAB, validated German version) for which we developed a diagnostic cut-off in healthy elderly volunteers. Systemic C-reactive protein (CRP) and interleukin 6 (IL-6) were measured preoperatively, 2 days postoperatively, and 7 days postoperatively. Values for CRP, IL-6, operative characteristics and hospital length of stay in patients with POCD and without POCD were compared using the Mann- Whitney U test and are shown as median [range]. Results: Fourteen patients (45%) developed POCD. Values for CRP were not statistically different in patients with POCD and without POCD but tended to be higher in patients with POCD 2 days postoperatively. Patients with POCD had significantly higher IL-6 values on postoperative days 2 and 7 (table 1). These patients also had a significantly longer duration of anaesthesia (305 [195-620] vs.190 [150-560] min, p = 0.034), larger intraoperative blood loss (425 [0-1600] vs. 100 [0-1500] ml, p = 0.018) and longer hospital stays (15 [8-45] vs. 8 [4-40] days, p = 0.008). Table 1 POCD (n = 14) No POCD (n = 17) p value CRP (mg/dl) preop. 4.0 [1.0-245] 4.2 [0.3-36.2] 0.6 2 days postop. 223 [20-318] 98 [4.5-384] 0.07 7 days postop. 58 [15-147] 44 [11-148] 0.2 IL-6 (U/ml) preop. 2[2-28.1] 2 [2-7.3] 0.8 2 days postop. 56 [17-315] 20 [2-123] 0.009 7 days postop. 9[2-77] 4 [2-16] 0.03 Interpretation: In this small group of patients, high IL-6 values postoperatively were associated with POCD supporting a role for systemic inflammation in the development of POCD. In patients with POCD, duration of anaesthesia was significantly longer, and intraoperative blood losses were larger. These risk factors will need to be confirmed in a larger group of patients. The difference in length of stay may be indicative of postoperative complications, which have been linked to POCD earlier.

Personality traits influence clinical outcome in day hospital-treated elderly depressed patients

OBJECTIVES: Although personality traits are considered significant predictors of both physical and mental health, their specific impact on treatment outcome in elderly patients with depression remains largely unexplored. Impact of personality traits on the evolution of depressive symptoms, quality of life, and perception of clinical progress was assessed in a psychotherapeutic community. DESIGN: A prospective longitudinal study was conducted in 62 elderly outpatients. SETTING: Day hospital treatment as usual combined group and individual therapies, pharmacological treatment, as well as family and network meetings. PARTICIPANTS: Patients presented with major depression or a depressive episode of bipolar disease. MEASUREMENTS: The Geriatric Depression Scale, the Short Form Survey, and the Therapeutic Community Assessment scale were administrated at admission, 3, 6, 12 months, and at discharge. Personality was evaluated with the NEO Five-Factor Personality Inventory. RESULTS: Outcome revealed reduced depression and improved mental quality of life and clinical progress. Higher Geriatric Depression Scale scores were found in individuals with higher levels of Neuroticism (and its Vulnerability facet). Better self-perception of clinical progress was observed in individuals with lower levels of the Depressiveness and Modesty facets and higher openness to action. Improvement in quality of life was predicted by high Positive emotions facet. All these associations remained significant after controlling for age, gender, and treatment length. CONCLUSION: Personality traits may predict clinical outcome in psychotherapeutic hospital day care for elderly patients with depression.

Incidence of bullous pemphigoid and pemphigus in Switzerland: a 2-year prospective study.

BACKGROUND: Bullous pemphigoid (BP), pemphigus vulgaris (PV) and pemphigus foliaceus (PF) are autoimmune bullous diseases characterized by the presence of tissue-bound and circulating autoantibodies directed against disease-specific target antigens of the skin. Although rare, these diseases run a chronic course and are associated with significant morbidity and mortality. There are few prospective data on gender- and age-specific incidence of these disorders. OBJECTIVES: Our aims were: (i) to evaluate the incidence of BP and PV/PF in Swiss patients, as the primary endpoint; and (ii) to assess the profile of the patients, particularly for comorbidities and medications, as the secondary endpoint. METHODS: The protocol of the study was distributed to all dermatology clinics, immunopathology laboratories and practising dermatologists in Switzerland. All newly diagnosed cases of BP and pemphigus occurring between 1 January 2001 and 31 December 2002 were collected. In total, 168 patients (73 men and 95 women) with these autoimmune bullous diseases, with a diagnosis based on clinical, histological and immunopathological criteria, were finally included. RESULTS: BP showed a mean incidence of 12.1 new cases per million people per year. Its incidence increased significantly after the age of 70 years, with a maximal value after the age of 90 years. The female/male ratio was 1.3. The age-standardized incidence of BP using the European population as reference was, however, lower, with 6.8 new cases per million people per year, reflecting the ageing of the Swiss population. In contrast, both PV and PF were less frequent. Their combined mean incidence was 0.6 new cases per million people per year. CONCLUSIONS; This is the first comprehensive prospective study analysing the incidence of autoimmune bullous diseases in an entire country. Our patient cohort is large enough to establish BP as the most frequent autoimmune bullous disease. Its incidence rate appears higher compared with other previous studies, most likely because of the demographic characteristics of the Swiss population. Nevertheless, based on its potentially misleading presentations, it is possible that the real incidence rate of BP is still underestimated. Based on its significant incidence in the elderly population, BP should deserve more public health concern.

Metabolic syndrome is associated with colorectal cancer in men.

AIM OF THE STUDY: We assessed the relation between metabolic syndrome (MetS) and its components and colorectal cancer. METHODS: We analysed data from a multicentre case-control study conducted in Italy and Switzerland, including 1378 cases of colon cancer, 878 cases of rectal cancer and 4661 controls. All cases were incident and histologically confirmed. Controls were subjects admitted to the same hospitals as cases with acute non-malignant conditions. MetS was defined according to the International Diabetes Federation criteria. Odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) were estimated by multiple logistic regression models, including terms for major identified confounding factors for colorectal cancer. RESULTS: With reference to each component of the MetS, the ORs of colorectal cancer in men were 1.27 (95% CI, 0.95-1.69) for diabetes, 1.24 (95% CI, 1.03-1.48) for hypertension, 1.14 (95% CI, 0.93-1.40) for hypercholesterolaemia and 1.26 (95% CI, 1.08-1.48) for overweight at age 30. The corresponding ORs in women were 1.20 (95% CI, 0.82-1.75), 0.87 (95% CI, 0.71-1.06), 0.83 (95% CI, 0.66-1.03) and 1.06 (95% CI, 0.86-1.30). Colorectal cancer risk was increased in men (OR=1.86; 95% CI, 1.21-2.86), but not in women (OR=1.13; 95% CI, 0.66-1.93), with MetS. The ORs were 2.09 (95% CI, 1.38-3.18) in men and 1.15 (95% CI, 0.68-1.94) in women with > or =3 components of the MetS, as compared to no component. Results were similar for colon and rectal cancers. CONCLUSION: This study supports a direct association between MetS and both colon and rectal cancers in men, but not in women.

Associations of physical activity and sport and exercise with at-risk substance use in young men: a longitudinal study.

OBJECTIVE: This study aims to measure the associations of physical activity and one of its components, sport and exercise, with at-risk substance use in a population of young men. METHOD: Baseline (2010-2012) and follow-up (2012-2013) data of 4748 young Swiss men from the Cohort Study on Substance Use Risk Factors (C-SURF) were used. Cross-sectional and prospective associations between at-risk substance use and both sport and exercise and physical activities were measured using Chi-squared tests and logistic regression models adjusting for covariates. RESULTS: At baseline, logistic regression indicated that sport and exercise is negatively associated with at-risk use of cigarettes and cannabis. A positive association was obtained between physical activity and at-risk alcohol use. At baseline, sport and exercise was negatively associated with at-risk use of cigarettes and cannabis at follow-up. Adjusted for sport and exercise, physical activity was positively associated with at-risk use of cigarettes and cannabis. CONCLUSION: Sport and exercise is cross-sectionally and longitudinally associated with a low prevalence of at-risk use of cigarettes and cannabis. This protective effect was not observed for physical activity broadly defined. Taking a substance use prevention perspective, the promotion of sport and exercise among young adults should be encouraged.

Protein turnover and thermogenesis in response to high-protein and high-carbohydrate feeding in men.

The rates of energy expenditure and wholebody protein turnover were determined during a 9-h period in a group of seven men while they received hourly isocaloric meals of high-protein (HP) or high-carbohydrate (HC) content. Their responses to feeding were compared with those to a short period of fasting (15-24 h). The 9-h thermic response to the repeated feeding of HP meals was found to be greater than that to the HC meals (9.6 +/- 0.6% vs 5.7 +/- 0.4% of the energy intake, respectively, means +/- SEM, p less than 0.01). The rate of whole-body nitrogen turnover over 9 h increased from 17.6 +/- 2.2 g on the fasting day to 27.4 +/- 1.4 g during HC feeding (NS) and there was a further increase to 58.2 +/- 5.3 g resulting from HP feeding (p less than 0.001). By using theoretical estimates (based upon ATP requirements) of the metabolic cost of protein synthesis, 36 +/- 9% of the thermic response to HC feeding and 68 +/- 3% of the response to HP feeding could be accounted for by the increases in protein synthesis compared with the fasting state.

Elderly age is not a negative predictive factor for virological response to therapy with pegylated interferon-α and ribavirin in chronic hepatitis C virus patients.

BACKGROUND & AIMS: Age is frequently discussed as negative host factor to achieve a sustained virological response (SVR) to antiviral therapy of chronic hepatitis C. However, elderly patients often show advanced fibrosis/cirrhosis as known negative predictive factor. The aim of this study was to assess age as an independent predictive factor during antiviral therapy. METHODS: Overall, 516 hepatitis C patients were treated with pegylated interferon-α and ribavirin, thereof 66 patients ≥60 years. We analysed the impact of host factors (age, gender, fibrosis, haemoglobin, previous hepatitis C treatment) and viral factors (genotype, viral load) on SVR per therapy course by performing a generalized estimating equations (GEE) regression modelling, a matched pair analysis and a classification tree analysis. RESULTS: Overall, SVR per therapy course was 42.9 and 26.1%, respectively, in young and elderly patients with hepatitis C virus (HCV) genotypes 1/4/6. The corresponding figures for HCV genotypes 2/3 were 74.4 and 84%. In the GEE model, age had no significant influence on achieving SVR. In matched pair analysis, SVR was not different in young and elderly patients (54.2 and 55.9% respectively; P = 0.795 in binominal test). In classification tree analysis, age was not a relevant splitting variable. CONCLUSIONS: Age is not a significant predictive factor for achieving SVR, when relevant confounders are taken into account. As life expectancy in Western Europe at age 60 is more than 20 years, it is reasonable to treat chronic hepatitis C in selected elderly patients with relevant fibrosis or cirrhosis but without major concomitant diseases, as SVR improves survival and reduces carcinogenesis.
