"We literally worked in parking lots, cars, garages, and separately set up party tents": qualitative study on the experiences of GPs in the frame of the SARS-CoV-2 pandemic in Austria.

BACKGROUND: Primary care is internationally recognised as one of the cornerstones of health care. During the COVID-19 pandemic, primary care physicians were assigned a variety of tasks and thus made a significant contribution to a country's pandemic response. They were expected to perform a variety of tasks, such as diagnosing and treating people with COVID-19, maintaining health care for all other patients, as well as several public health tasks, such as diagnostic testing and vaccination, protecting patients and staff from infection, and serving as community trusted persons. In Austria, there are no structured levels of care, no definition of the role of the general practitioner during a pandemic is given, and no specific support structures are present. The aim of this study was to assess the views and experiences of primary care physicians regarding supportive and hindering factors for pandemic preparedness in Austria. METHODS: Qualitative study using semi-structured interviews. A total of 30 general practitioners were interviewed, with particular attention to an equitable distribution in small, medium and large primary care facilities. Qualitative content analysis was performed. RESULTS: Interviewees described a wide range of infection control, organisational and communication measures that they had implemented. They made changes to practise equipment, found makeshift solutions when supplies were scarce, and established communication and information pathways when official communication lines were inadequate. CONCLUSION: General practitioners took on essential tasks and showed a high level of understanding of their role in the pandemic response. This was achieved mainly at an informal level and with high personal commitment. Their functioning in the absence of structural regulations and support shows that they had a clear intrinsic understanding of their responsibilities. To ensure reliability and sustainability and to reduce their burden, it will be necessary to clarify the role and tasks of a general practitioner and to provide the necessary support. This concerns both infrastructural support and communication and information strategies. As part of the reform to strengthen primary care, primary care needs to be seen, valued and involved in decision-making processes.

Quantification of serotonin and eight of its metabolites in plasma of healthy volunteers by mass spectrometry.

Serotonin is transformed into melatonin under the control of the light/dark cycle, representing a cornerstone of circadian rhythmicity. Serotonin also undergoes extensive metabolism to produce 5-hydroxyindoleacetic acid (5-HIAA), a biomarker for the diagnosis and monitoring of serotonin secreting neuroendocrine tumors (NETs). While serotonin, melatonin and their metabolites are part of an integrated comprehensive system, human observations about their respective plasma concentrations are still limited. We report here for the first time a multiplex UHPLC-MS/MS assay for the quantification of serotonin, 5-HIAA, 5-hydroxytryptophol (5-HTPL), N-acetyl-serotonin (NAS), Mel, 6-OH-Mel, 5-methoxytryptamine (5-MT), 5-methoxytryptophol (5-MTPL), and 5-methoxyindoleacetic acid (5-MIAA) in human plasma. Analytes were extracted by protein precipitation and solid phase extraction. Plasma concentrations for these analytes were determined in 102 healthy volunteers. The LLOQ of the assay ranges from 2.2 nM for serotonin to 1.0 pM for 6-OH-Mel. This sensitivity enables the quantification of circulating serotonin, 5-HIAA, NAS, Mel, and 5-MIAA, even at their lowest diurnal concentrations. This assay will enable specific, precise and accurate measurement of serotonin, Mel and their metabolites to draw a detailed picture of this complex pineal metabolism, allowing a dynamic understanding of these pathways and providing promising biomarkers and a metabolic signature for serotonin-secreting NETs.

Functional weakness of the limbs has an uncertain prognosis and little chance of recovery. Obese people in precarious situations may succeed in losing weight through an intensive lifestyle-based weight loss program. In patients with gonarthrosis, physiotherapy may decrease pain and disability when compared to injected corticosteroids. Patients suffering from an alcohol dependence syndrome can reduce their consumption with short-term consultations conducted by general practitioners. Fatigue and dyspnea are two frequent symptoms that may persist after the acute phase of the SARS-CoV-2 infection. PCR analysis for the detection of SARS-CoV-2 could be performed with the same degree of sensitivity on a nasopharyngeal or salivary swab.

La faiblesse fonctionnelle des membres a un pronostic incertain et peu de probabilité de guérir. Les personnes souffrant d'obésité en situation de précarité peuvent réussir à perdre du poids par un programme intensif de perte pondérale soutenu par des changements du style de vie. Chez les patients atteints de gonarthrose, la physiothérapie peut diminuer la douleur et l'incapacité lorsqu'elle est comparée à des corticostéroïdes injectés. Les patients qui souffrent d'un syndrome de dépendance à l'alcool peuvent réduire leur consommation avec des consultations de courte durée effectuées par des médecins généralistes. La fatigue et la dyspnée sont deux des symptômes parmi les plus fréquents qui peuvent perdurer après la phase aiguë de l'infection par SARS-CoV-2. L'analyse de détection du SARS-CoV-2 par PCR pourrait être effectuée avec le même degré de sensibilité sur un prélèvement nasopharyngé ou salivaire.

[Pharmacovigilance update]. / Pharmacovigilance.

The main pharmacovigilance updates in 2014 are reviewed. Ivabradine: increased risk of cardiovascular death and myocardial infarction in patients with symptomatic angina treated with high dosages. Clopidogrel: rare observations of acquired hemophilia. Orlistat: may reduce the absorption of HIV antiretrovirals. Ponatinib: increased risk of arteriopathy and thrombosis. Axitinib: significant risk of heart failure (class effect). Tocilizumab: possible causal relationship with the emergence or aggravation of psoriasis. Lithium: hypercalcemia and hyperparathyroidism commonly observed. Sildenalfil: suspected causal association with melanoma, so far not proven, Methylphenidate: rare observations of priapism. St John's wort (Hypericum): reduced effectiveness of hormonal contraceptives, including implants.
