How Can We Help Healthcare Workers during a Catastrophic Event Such as the COVID-19 Pandemic?

Healthcare workers (HCWs) have significantly suffered during the COVID-19 pandemic, reporting a high prevalence of anxiety, depression and post-traumatic stress disorder (PTSD). We investigated with this survey whether HCWs benefitted from supportive measures put in place by hospitals and how these measures were perceived. This cross-sectional survey, which was conducted during the first wave of COVID-19 at the Geneva University Hospitals, Switzerland, between May and July 2021, collected information on the use and perception of practical and mental health support measures provided by the hospital. In total, 3461 HCWs participated in the study. Regarding the practical support measures, 2896 (84%) participants found them useful, and 2650 (76%) used them. Regarding the mental health support measures, 3149 (90%) participants found useful to have the possibility of attending hypnosis sessions, 3163 (91%) to have a psychologist within hospital units, 3202 (93%) to have a medical nursing psychiatric permanence available seven days a week, and 3171 (92%) to have a hotline available seven days a week. In total, 436 (13%) HCWs used at least one of the available mental health support measures. During the COVID-19 pandemic, the support measures were valued by HCWs. Given the high prevalence of psychiatric issues among HCWs, these measures seem necessary and are likely to have alleviated the suffering of HCWs.

Hypophosphatemia on ICU Admission Is Associated with an Increased Length of Stay in the ICU and Time under Mechanical Ventilation.

Hypophosphatemia is frequently observed in the ICU and is associated with several impairments such as respiratory failure or infections. We hypothesized that hypophosphatemia on ICU admission is associated with a prolonged duration of mechanical ventilation and ICU length of stay (LOS), particularly in COVID-19 patients. This cross-sectional study analyzed data from 1226 patients hospitalized in the ICU of the Geneva University Hospitals from August 2020 to April 2021. Patients were categorized as having hypophosphatemia (phosphatemia ≤ 0.8 mmol/L) or non-hypophosphatemia (phosphatemia > 0.8 mmol/L) on ICU admission. Linear regressions were performed to investigate the association between hypophosphatemia on ICU admission and ICU LOS and duration of mechanical ventilation. Overall, 250 (20%) patients presented hypophosphatemia on ICU admission. In the univariable analysis, hypophosphatemic patients had longer ICU LOS than non-hypophosphatemic patients, 7.4 days (±10.4) versus 5.6 days (±8.3), (p < 0.01). Hypophosphatemia on ICU admission was associated with a prolonged duration of mechanical ventilation, 7.4 days (±11.2) versus 5.6 days (±8.9), (p < 0.01). These associations were confirmed in the multivariable analysis (p < 0.01). In the subgroup of COVID-19 patients, a significant association between hypophosphatemia and ICU LOS and duration of mechanical ventilation was also observed. In conclusion, hypophosphatemia on ICU admission is associated with a longer ICU LOS and time under mechanical ventilation, both in the general ICU population and in COVID-19 patients.

Vegetarian, pescatarian and flexitarian diets: sociodemographic determinants and association with cardiovascular risk factors in a Swiss urban population.

Prevalence and trends of different vegetarian diets remain unknown, with estimates varying depending on the source. Evidence suggests that vegetarian diets are associated with a more favourable cardiovascular risk profile. The present study aimed to assess the prevalence and trends of different types of vegetarian diets in a population-based representative sample, sociodemographic characteristics of participants following such diets and the association of these diets with cardiovascular risk factors. Using repeated cross-sectional population-based surveys conducted in Geneva, Switzerland, 10 797 individuals participated in the study between 2005 and 2017. Participants were classified as vegetarians, pescatarians, flexitarians or omnivores using an FFQ. Sociodemographic and cardiovascular risk factors were evaluated through questionnaires, anthropometric measurements and blood tests. Findings show prevalence of vegetarians increased from 0·5 to 1·2 %, pescatarians from 0·3 to 1·1 % and flexitarians remained stable at 15·6 % of the population over the study period. Compared with omnivores, vegetarians were more likely to be young (OR 2·38; 95 % CI 1·01, 5·6), have higher education (OR 1·59; 95 % CI 1·01, 2·49) and lower income (OR 1·83; 95 % CI 1·04, 3·21); pescatarians and flexitarians were more likely to be women (pescatarian: OR 1·81; 95 % CI 1·10, 3·00; vegetarian: OR 1·57; 95 % CI 1·41, 1·75) and flexitarians were also more likely to have a lower income (OR 1·31; 95 % CI 1·13, 1·53). Participants who adhered to any diet excluding/reducing meat intake had lower BMI, total cholesterol and hypertension compared with omnivores. The present study shows an increase in the prevalence of vegetarians over a 13-year period and suggests that the different vegetarian diets assessed are associated with a better cardiovascular risk profile.

[Vegetarian and vegan diets and their impact on health]. / Alimentations végétariennes et véganes†: quelles conséquences sur la santé†?

Vegetarian and vegan diets are increasing in the population, but the prevalence remains low (< 3 %). Vegetarians consume diary and eggs while vegans do not consume or use any animal derived products. Vegetarians have a low risk of deficiency except for iron deficiency with anemia in pre-menopausal women. Vegans should receive a mandatory vitamin B12 substitution because of an important risk of deficiency. Furthermore, vegans are at higher risk of iron and calcium deficiency with higher rates of osteoporotic fracture and iron deficiency anemia. Dietary advice is recommended, particularly for vegans, even though no clear recommendations can be found in the literature. These diets seem to be associated with a reduction in cardio-vascular risk factors, but this association remains to be confirmed.

La prévalence des végétariens et véganes dans la population générale augmente, mais reste faible (< 3 %). Au contraire des véganes qui ne consomment que des produits d'origine végétale, les végétariens consomment des produits laitiers et des œufs. Les végétariens présentent peu de risque de carence mis à part un risque d'anémie ferriprive chez les femmes préménopausées. Les véganes, quant à eux, doivent être substitués systématiquement en vitamine B12 en raison d'un risque élevé de carence. Ils sont aussi plus à risque de carence en calcium et en fer, avec des taux de fracture ostéoporotique et de carence martiale plus élevés. Un suivi diététique est conseillé, en particulier pour les véganes, malgré l'absence de recommandations claires de la littérature. Ces régimes semblent améliorer de nombreux facteurs de risque cardiovasculaire mais ces effets restent à confirmer.
