Mapping the transcription start points of the Staphylococcus aureus eap, emp, and vwb promoters reveals a conserved octanucleotide sequence that is essential for expression of these genes.

Mapping the transcription start points of the eap, emp, and vwb promoters revealed a conserved octanucleotide sequence (COS). Deleting this sequence abolished the expression of eap, emp, and vwb. However, electrophoretic mobility shift assays gave no evidence that this sequence was a binding site for SarA or SaeR, known regulators of eap and emp.

Cost-effectiveness analysis of a European primary-care physician training in smoking cessation counseling.

BACKGROUND: Physician training in smoking cessation counseling has been shown to be effective as a means to increase quit success. We assessed the cost-effectiveness ratio of a smoking cessation counseling training programme. Its effectiveness was previously demonstrated in a cluster randomized, control trial performed in two Swiss university outpatients clinics, in which residents were randomized to receive training in smoking interventions or a control educational intervention. DESIGN AND METHODS: We used a Markov simulation model for effectiveness analysis. This model incorporates the intervention efficacy, the natural quit rate, and the lifetime probability of relapse after 1-year abstinence. We used previously published results in addition to hospital service and outpatient clinic cost data. The time horizon was 1 year, and we opted for a third-party payer perspective. RESULTS: The incremental cost of the intervention amounted to US$2.58 per consultation by a smoker, translating into a cost per life-year saved of US$25.4 for men and 35.2 for women. One-way sensitivity analyses yielded a range of US$4.0-107.1 in men and US$9.7-148.6 in women. Variations in the quit rate of the control intervention, the length of training effectiveness, and the discount rate yielded moderately large effects on the outcome. Variations in the natural cessation rate, the lifetime probability of relapse, the cost of physician training, the counseling time, the cost per hour of physician time, and the cost of the booklets had little effect on the cost-effectiveness ratio. CONCLUSIONS: Training residents in smoking cessation counseling is a very cost-effective intervention and may be more efficient than currently accepted tobacco control interventions.

The personality profile of borderline personality disordered patients using the five-factor model of personality

The purpose of this ex post facto study is to analyze the personality profile of outpatients who met criteria for borderline personality disorder according to the Five-Factor Model of personality. All patients (N = 52) completed the International Personality Disorder Examination (IPDE) Screening Questionnaire, the Big Five Questionnaire (BFQ), the Beck Depression Inventory (BDI), and the Beck Hopelessness Scale (BHS). The results show a high comorbidity with other DSM-IV-TR Axis II disorders, in particular with those from Cluster C. The BFQ average score indicates that the outpatients who met borderline criteria score lower than controls on all five dimensions, and especially on emotional stability. Correlations were computed between the BFQ and the IPDE scales in our sample. These results suggest that specific personality profile are linked to different comorbidity patterns. More than a half of our sample has clinically significant scores on Beck's scales. Surprisingly, depression and hopelessness are neither correlated with the borderline scale, nor have an effect in the relationship between personality and personality disorders.

Early mobilization out of bed after ischaemic stroke reduces severe complications but not cerebral blood flow: a randomized controlled pilot trial.

OBJECTIVE: To evaluate whether early mobilization after acute ischaemic stroke is better than delayed mobilization with regard to medical complications and if it is safe in relation to neurological function and cerebral blood flow. DESIGN: Randomized controlled pilot trial of early versus delayed mobilization out of bed with incidence of severe complications as the primary outcome. SETTING: Acute stroke unit in the neurology department of a University Hospital. PARTICIPANTS: Fifty patients after ischaemic stroke with a National Institutes of Health Stroke Scale (NIHSS) score >6 were recruited. INTERVENTION: All patients were treated with physiotherapy immediately after their admission. In the early protocol patients were mobilized out of bed after 52 hours, in the delayed protocol after seven days. RESULTS: Eight out of 50 randomized patients were excluded from the per-protocol analysis because of early transfer to other hospitals. There were 2 (8%) severe complications in the 25 early mobilization patients and 8 (47%) in the 17 delayed mobilization patients (P < 0.006). There were no differences in the total number of complications or in clinical outcome. In the 26 patients (62%) who underwent serial transcranial Doppler ultrasonography, no blood flow differences were found. CONCLUSION: We found an apparent reduction in severe complications and no increase in total complications with an early mobilization protocol after acute ischaemic stroke. No influence on neurological three-month outcomes or on cerebral blood flow was seen. These results justify larger trials comparing mobilization protocols with possibly even faster mobilization out of bed than explored here.

Activity and behavior of blowflies on pig liver baits in spring

Des pièges attractifs contenant du foie frais et du foie âgé de 2 et 4 jours ont été utilisés au cours de 9 journées de capture (avril à mai 1999). Parmi les 451 spécimens récoltés, 7 espèces de Calliphoridae ont été identifiées. Les conditions météorologiques, exprimées par la pluie, la température et les radiations solaires, ont une influence signficative sur l'activité des mouches. A l'exception de Lucilia sericata et L. Illustris, les autres espèces montrent une nette préférence pour les pièges contenant du foie de 4 jours. Le sex-ratio est toujours en faveur des femelles et varie de 1.7:1 (L. silvarum) à 18.8:1 (L. illustris).

Efeitos do paclobutrazol em diferentes concentrações e períodos de imersão na cultura do alho

O presente trabalho foi conduzido no período de abril a setembro de 1989 no Campo Experimental do Setor de Olericultura da UFLA, Lavras, MG, com o objetivo de avaliar a influência de concentrações e períodos de imersão em paclobutrazol sobre o controle do pseudoperfilhamento e características comerciais do alho (Allium sativum L.). Utilizou-se o delineamento experimental de blocos ao acaso em esquema fatorial 4 x 5, compreendendo quatro doses de paclobutrazol (0, 500, 1.000 e 1.500 mg L-1 de i.a.) e cinco períodos de imersão (30, 60, 90, 120 e 150 minutos) e quatro repetições. Observou-se, com o incremento das concentrações de paclobutrazol, uma redução na altura e no número de folhas por planta aos 60 e 90 dias após o plantio. A concentração de 976 mg L-1 de paclobutrazol proporcionou o maior peso médio de bulbo, e a dose de 451 mg L-1 foi a que promoveu a maior porcentagem de bulbos graúdos. Quanto a produtividade total e comercial, porcentagem de bulbos pseudoperfilhados e número de bulbilhos por bulbo, não se verificaram diferenças significativas entre os tratamentos.

Efeito da adubação e do calcário na produção de matéria seca e de óleo essencial de pimenta-longa

O objetivo deste trabalho foi estudar o efeito de diferentes doses de N, P e K, em solo que recebeu ou não calcário, sobre a produção de matéria seca e de óleo essencial de pimenta-longa (Piper hispidinervum C. DC.). Utilizou-se o delineamento experimental de blocos casualizados, com três repetições. Os tratamentos foram arranjados no esquema fatorial 3 x 3 x 3, com três doses de N (0, 8 e 16 g/planta de N), P (0, 5 e 10 g/planta de P2O5) e K (0, 5 e 10 g/planta de K2O). Aos 6 e 12 meses após o transplantio, foi avaliada a produção de matéria seca de ramos e folhas, e de óleo essencial. As doses de P promoveram efeito quadrático sobre a produção de matéria seca, com respostas máximas obtidas com 7,1 e 9,6 g/planta de P2O5, no solo que recebeu ou não calcário, respectivamente. Em solo não calcareado, as doses de N promoveram efeito quadrático sobre as produções de matéria seca e de óleo essencial, com os pontos de máxima de 10,2 e 9,4 g/planta de N, respectivamente. O P foi o nutriente que promoveu efeito mais pronunciado no aumento da produção de matéria seca. As médias de produção de matéria seca e de óleo essencial foram maiores no ensaio onde o solo foi calcareado (6.451 kg/ha e 167 L/ha, respectivamente), do que as obtidas no solo não calcareado (5.003 kg/ha e 145 L/ha, respectivamente).

Fibrose pulmonaire idiopathique: nouveautés diagnostiques et thérapeutiques [Idiopathic pulmonary fibrosis: recent diagnostic and therapeutic advances].

Idiopathic pulmonary fibrosis (IPF) is the most frequent of the idiopathic interstitial pneumonias. It is a progressive disorderwith a poor prognosis. Its diagnosis requires the careful exclusion of potential causes, and a pattern of usual interstitial pneumonia at high-resolution computed tomography or video-assisted surgical lung biopsy. Several recent randomized trials have profoundly modified the therapeutic management of IPF. The combination of prednisone and azathioprine, often prescribed until recently, has been shown to be harmful and is no longer indicated. N-acetylcystein, also used in the past decade, failed to show an efficacy. However, two new antifibrotic drugs, pirfenidone and nintedanib, have for the first time proven effective in slowing disease progression.

Interruptions of cART limits CD4 T-cell recovery and increases the risk for opportunistic complications and death.

BACKGROUND: A major goal of antiretroviral therapy (ART) for HIV-1-infected persons is the recovery of CD4 T lymphocytes, resulting in thorough protection against opportunistic complications. Interruptions of ART are still frequent. The long-term effect on CD4 T-cell recovery and clinical events remains unknown. METHODS: Immunological and clinical endpoints were evaluated in 2491 participants of the Swiss HIV Cohort Study initiating ART during a mean follow-up of 7.1 years. Data were analysed in persons with treatment interruptions (n = 1271; group A), continuous ART, but intermittent HIV-1 RNA at least 1000 copies/ml (n = 469; group B) and continuous ART and HIV-1 RNA constantly less than 1000 copies/ml (n = 751; group C). Risk factors for low CD4 T-cell counts and clinical events were analysed using Cox proportional hazards models. RESULTS: In groups A-C, CD4 T lymphocytes increased to a median of 427, 525 and 645 cells/μl at 8 years. In group A, 63.0 and 37.2% reached above 350 and 500 CD4 T cells/μl, whereas in group B 76.3 and 55.8% and in group C 87.3 and 68.0% reached these thresholds (P < 0.001). CD4 T-cell recovery directly depended on the cumulative duration of treatment interruptions. In addition, participants of group A had more Centers for Disease Control and Prevention B/C events, resulting in an increased risk of death. Major risk factors for not reaching CD4 T cells above 500 cells/μl included lower baseline CD4 T-cell count, higher age and hepatitis C virus co-infection. CONCLUSION: In persons receiving continuous ART larger CD4 T-cell recovery and a reduced risk for opportunistic complications and death was observed. CD4 T-cell recovery was smaller in persons with treatment interruptions more than 6 months.

Levels and determinants of inflammatory biomarkers in a Swiss population-based sample (CoLaus Study).

OBJECTIVE: to assess the levels and determinants of interleukin (IL)-1ß, IL-6, tumour necrosis factor (TNF)-a and C-reactive protein (CRP) in a healthy Caucasian population.METHODS: population sample of 2884 men and 3201 women aged 35 to 75. IL-1ß, IL-6 and TNF-a were assessed by a multiplexed particle-based flow cytometric assay and CRP by an immunometric assay.RESULTS: Spearman rank correlations between duplicate cytokine measurements (N?=?80) ranged between 0.89 and 0.96; intra-class correlation coefficients ranged between 0.94 and 0.97, indicating good reproducibility. Among the 6085 participants, 2289 (37.6%), 451 (7.4%) and 43 (0.7%) had IL-1ß, IL-6 and TNF-a levels below detection limits, respectively. Median (interquartile range) for participants with detectable values were 1.17 (0.48-3.90) pg/ml for IL-1ß; 1.47 (0.71-3.53) pg/ml for IL-6; 2.89 (1.82-4.53) pg/ml for TNF-a and 1.3 (0.6-2.7) ng/ml for CRP. On multivariate analysis, greater age was the only factor inversely associated with IL-1ß levels. Male sex, increased BMI and smoking were associated with greater IL-6 levels, while no relationship was found for age and leisure-time PA. Male sex, greater age, increased BMI and current smoking were associated with greater TNF-a levels, while no relationship was found with leisure-time PA. CRP levels were positively related to age, BMI and smoking, and inversely to male sex and physical activity.CONCLUSION: Population-based levels of several cytokines were established. Increased age and BMI, and to a lesser degree sex and smoking, significantly and differentially impact cytokine levels, while leisure-time physical activity has little effect.

Association of statins with inflammatory cytokines: a population-based Colaus study.

PURPOSE: A pleiotropic effect of statins has been reported in numerous studies. However, the association between statin use and inflammatory cytokines is controversial. We examined the associations between statin use and C-reactive protein (CRP), tumour necrosis factor α (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6) in a healthy Caucasian population. METHODS: Cross-sectional study of 6184 participants aged 35-75years from Lausanne, Switzerland. Cytokines were assessed by multiplexed particle-based flow cytometric assay. Self-reported history of medication was collected for statins and other medication. 99 participants without cytokine data were excluded. RESULTS: Among the 6085 participants, 2289 (37.6%), 451 (7.4%) and 43 (0.7%) had IL-1β, IL-6 and TNF-α levels below detection limits, respectively. On multivariate analysis adjusting for age, gender, smoking status, body mass index, hypertension, diabetes, baseline cardiovascular disease, total cholesterol, anti-inflammatory use, other cytokine modifying drugs and other drugs, participants on statins had significantly lower CRP levels (adjusted mean±standard error: 1.22±1.05 vs. 1.38±1.04mg/L for use and non-use, respectively, p<0.01 on log-transformed data). Conversely, no association was found between statin use and IL-1β (p=0.91), IL-6 (p=0.25) or TNF-α (p=0.28) levels. On multivariate analysis, individuals in the statin group (β coefficient=-0.12; 95% CI=-0.21, -0.03) had lower levels of CRP as compared to those in the reference group (i.e. those not using statin). However, no significant associations were observed between IL-1β, IL-6 and TNF-α and statins. CONCLUSION: Individuals on statins have lower CRP levels; conversely, no effect was found for IL-1β, IL-6 and TNF-α levels.
