Arbeitsmedizin

Das Kapitel ist in vier Unterkapital gegliedert. "Allgemeines zur Arbeitsmedizin" beinhaltet die Rolle und Ziele der Arbeitsmedizin und die wesentlichen gesetzlichen Grundlagen. "Berufskrankheiten" umfasst die Berufs- und Arbeitsplatzanamnese sowie die wichtigsten Berufskrankheiten und Noxen. Das dritte Unterkapitel behandelt die arbeitsassoziierten Gesundheitsstörungen, die Ergonomie, Arbeitsorganisation und Arbeitslosigkeit. Die Kapitel "Absenzen- und Case Management" sowie "Betriebliche Gesundheitsförderung und Arbeitsgestaltung" zeigen Möglichkeiten auf, wie ein Betrieb die Gesundheit und Arbeitsfähigkeit seiner Mitarbeiter aufrechterhalten und fördern kann. Das Kapitel befähigt die Studierenden, die Interaktion zwischen Arbeit und Gesundheit zu erkennen und adäquate Massnahmen zu ergreifen.[Autoren]]]> Occupational Medicine ; Occupational Diseases oai:serval.unil.ch:BIB_EFD9005BC107 2020-05-30T01:25:30Z phdthesis urnserval https://serval.unil.ch/notice/serval:BIB_EFD9005BC107 Résultats à court terme des arthroplasties totales de hanche non cimentées chez des patients de moins de 60 ans Larequi, Ivan-Philippe Université de Lausanne, Faculté de médecine info:eu-repo/semantics/doctoralThesis phdthesis 1999 fre https://serval.unil.ch/resource/serval:BIB_EFD9005BC107.P001/REF.pdf http://nbn-resolving.org/urn/resolver.pl?urn=urn:nbn:ch:serval-BIB_EFD9005BC1073 info:eu-repo/semantics/altIdentifier/urn/urn:nbn:ch:serval-BIB_EFD9005BC1073 info:eu-repo/semantics/restrictedAccess Restricted: indefinite embargo Copying allowed only for non-profit organizations https://serval.unil.ch/disclaimer application/pdf oai:serval.unil.ch:BIB_EFD90D5BB70B 2020-05-30T01:25:30Z openaire documents urnserval https://serval.unil.ch/notice/serval:BIB_EFD90D5BB70B Association Between Plasma Caffeine and Other Methylxanthines and Metabolic Parameters in a Psychiatric Population Treated With Psychotropic Drugs Inducing Metabolic Disturbances info:doi:10.3389/fpsyt.2018.00573 info:eu-repo/semantics/altIdentifier/doi/10.3389/fpsyt.2018.00573 info:eu-repo/semantics/altIdentifier/pmid/30473668 Delacrétaz, Aurélie Vandenberghe, Frederik Glatard, Anaïs Levier, Axel Dubath, Céline Ansermot, Nicolas Crettol, Séverine Gholam-Rezaee, Mehdi Guessous, Idris Bochud, Murielle von Gunten, Armin Conus, Philippe Eap, Chin B. info:eu-repo/semantics/article article 2018-11-09 Frontiers in Psychiatry, vol. 9 info:eu-repo/semantics/altIdentifier/pissn/1664-0640 <![CDATA[Importance: Multiple studies conducted in the general population identified an association between self-reported coffee consumption and plasma lipid levels. To date, no study assessed whether and which plasma methylxanthines (caffeine and/or its metabolites, i.e., paraxanthine, theophylline, and theobromine) are associated with plasma lipids. In psychiatric patients, an important coffee consumption is often reported and many psychotropic drugs can induce a rapid and substantial increase of plasma lipid levels. Objective: To determine whether plasma methylxanthines are associated with metabolic parameters in psychiatric patients receiving treatments known to induce metabolic disturbances. Design, Setting, and Participants: Data were obtained from a prospective study including 630 patients with metabolic parameters [i.e., body mass index (BMI), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), non-high-density lipoprotein cholesterol (non-HDL-C), and fasting triglycerides (TG)] monitored routinely during psychotropic treatment. Exposures: Plasma methylxanthines levels. Main Outcomes and Measures: Metabolic variables including BMI and plasma lipid levels. Results: Multivariate analyses indicated that BMI, TC, HDL-C, and non-HDL-C increased significantly with increasing total methylxanthines (pcorrected &lt;= 0.05). In addition, compared to patients with plasma caffeine concentration in the lowest quartile, those with caffeine concentration in the highest quartile were twice more prone to suffer from non-HDL hypercholesterolemia (p(corrected) = 0.05), five times more likely to suffer from hypertriglyceridemia (p(corrected) = 0.01) and four times more susceptible to be overweight (p(corrected) = 0.01). Conclusions and Relevance: This study showed that plasma caffeine and other methylxanthines are associated with worsening of metabolic parameters in patients receiving psychotropic treatments known to induce metabolic disturbances. It emphasizes that important caffeine consumption could be considered as an additional environmental risk factor for metabolic worsening in patients receiving such treatments

Cannabis Use as a Protective Factor Against Overweight in HIV-Hepatitis C Virus Co-Infected People (ANRS CO13 HEPAVIH Cohort)

International audienceOverweight is increasingly prevalent in people living with HIV (PLWH), and is a high risk factor for metabolic disorders in this population. PLWH co-infected with hepatitis C virus (HCV) have a higher risk of metabolic disorders than their mono-infected counterparts. The putative relationship between cannabis use and body weight found in the general population has never been documented in HIV-HCV co-infected people. We tested whether cannabis use is associated with body mass index (BMI), overweight, and underweight in HCV co-infected PLWH (N = 992). Mixed-effects linear and logistic regression models were used to study the association between cannabis use and the three outcomes over time. After multivariable adjustment, cannabis use was inversely associated with BMI. Cannabis use was associated with a lower and higher risk of overweight and underweight, respectively. Cannabis use should be assessed and taken into account in the clinical management of the HIV-HCV co-infected population

One-month humoral response following two or three doses of mRNA Covid-19 vaccines as primary vaccination in specific populations in France: first results from the ANRS0001S COV-POPART cohort

International audienceObjectives: We aimed to investigate the one-month humoral response to two or three doses as primary vaccination in specific populations compared to healthy adults.Methods: ANRS0001S-COV-POPART (NCT04824651) is a French nationwide multicenter prospective observational cohort study assessing the immune response to Covid-19 vaccines routinely administered to 11 subgroups of patients with chronic conditions and two control groups. Patients and controls who had received at least two vaccine doses and whose results at one month after the second dose were available have been included. Humoral response was assessed at 1-month post first dose, post second dose and post third dose (if applicable), through the percentage of responders (positive anti-Spike SARS-CoV-2 IgG antibodies, geometric means of anti-Spike SARS-CoV-2 IgG antibodies (ELISA) and proportion of participants with anti-SARS-CoV-2-specific neutralizing antibodies (in vitro neutralization assay for the original SARS-CoV-2 strain). All analyses were centralized.Results: We included 4091 participants in this analysis: 2979 participants from specific subpopulations and 1112 controls. Only 522 (17.5%) of the specific populations received 3 doses as primary vaccination regimen. Patients living with HIV, cancer and diabetic patients had high rates of responders after two doses while solid organ transplant (SOT), allogeneic hematopoietic stem cell transplant (HSCT) and hypogammaglobulinemic patients had the lowest percentage of responders (35.9% [95%CI: 29.2; 43.0], 57.4% [48.1; 66.3]) and 77.1% [65.6; 86.3] respectively). In those who received a third dose, the rate of responders reached 54.2% [42.9-65.2] (vs. 32.3% (16.7-51.4) after 2 doses) in SOT and 73.9% [58.9-85.7) (vs. 56.1% [46.2-65.7] after 2 doses) in HSCT. Similar results were found with anti-SARS-CoV-2-specific neutralizing antibodies.Conclusions: Lower COVID-19 vaccine humoral response was observed in specific populations compared to controls. A third dose of vaccine in the primary regimen had a positive effect on both percentages of patients who developed anti-Spike IgG antibodies and specific neutralizing antibodies

Maintenance darunavir/ritonavir monotherapy to prevent perinatal HIV transmission, ANRS-MIE 168 MONOGEST study

International audienceObjectives: Because NRTIs can have fetal toxicities, we evaluated a perinatal NRTI-sparing strategy to prevent perinatal HIV transmission. Our primary objective was to determine the proportion maintaining a viral load (VL) of 50 copies/mL. Neonates received nevirapine prophylaxis for 14 days.Results: Of 89 patients switching to darunavir/ritonavir monotherapy, 4 miscarried before 22 weeks' gestation, 2 changed treatment for elevated liver enzymes without virological failure, and 83 were evaluable for the main outcome. Six had virological failure confirmed on a repeat sample (median VL=193 copies/mL; range 78-644), including two before switching to monotherapy. In these six cases, ART was intensified with tenofovir disoproxil fumarate/emtricitabine. The success rate was 75/83, 90.4% (95% CI, 81.9%-95.7%) considering two patients with VL missing at delivery as failures, and 77/83, 92.8% (95% CI, 84.9%-97.3%) when considering them as successes since both had undetectable VL on darunavir/ritonavir throughout pregnancy. In ITT, the last available VL before delivery was <50 copies/mL in all of the patients. There was no case of perinatal HIV transmission.Conclusions: Darunavir/ritonavir maintenance monotherapy required intensification in nearly 10% of cases. This limits its widespread use, thus other regimens should be evaluated in order to limit exposure to antiretrovirals, particularly NRTIs, during pregnancy

Reproducibility of fluorescent expression from engineered biological constructs in E. coli

We present results of the first large-scale interlaboratory study carried out in synthetic biology, as part of the 2014 and 2015 International Genetically Engineered Machine (iGEM) competitions. Participants at 88 institutions around the world measured fluorescence from three engineered constitutive constructs in E. coli. Few participants were able to measure absolute fluorescence, so data was analyzed in terms of ratios. Precision was strongly related to fluorescent strength, ranging from 1.54-fold standard deviation for the ratio between strong promoters to 5.75-fold for the ratio between the strongest and weakest promoter, and while host strain did not affect expression ratios, choice of instrument did. This result shows that high quantitative precision and reproducibility of results is possible, while at the same time indicating areas needing improved laboratory practices.Peer reviewe
