Mental health among the Moroccan population during SARS-CoV-2 outbreak: MAROCOVID study.

BACKGROUND: The SARS-CoV-2 pandemic's unpredictability and ambiguity, combined with the lockdown, social distancing, containment measures, and economic impact could increase the risk of mental health issues. OBJECTIVE: To assess the magnitude of mental health outcomes and risk factors among Moroccans, using an online survey, during the SARS-CoV-2 outbreak. METHODS: This cross-sectional, survey-based study collected demographic data and mental health measurements from 11,123 participants. The degree of depression, anxiety, and insomnia symptoms were assessed by the 9-item Patient Health Questionnaire, the 7-items Generalized Anxiety disorder, and the 7-items Insomnia Severity Index. RESULTS: The survey was completed by 11,123 individuals out of a total of 15,008 contacts. 7315 (65.8%) were women, and 7182 (64.6%) were aged 18 to 34. A significant proportion of respondents experienced depression (5894 [53%]), anxiety (5544 [49.8%]), and insomnia (4410 [39.6%]). Multivariable logistic regression analysis showed that being a woman, being married, and being a parent of children aged less than five years were associated with severe symptoms of depression and anxiety (e.g. severe depression among women vs. men (OR, 1.19; 95%CI, 1.06-1.33; P = .003), severe depression among married compared to unmarried respondents (OR, 1.92; 95%CI, 1.71-2.16; P < .000), e.g. severe anxiety among women vs. men (OR, 1.40; 95%CI, 1.24-1.58; <0.000), severe anxiety among married people compared to unmarried (OR, 1.14; 95%CI, 1.00-1.28; P < .003). CONCLUSION: Our findings reported a significant mental health burden on the general public during the COVID-19 lockdown. In addition to efforts deployed to prevent the spread of the disease, timely and culturally-specific mental health care needs to be developed urgently.

Randomised active programs on healthcare workers' flu vaccination in geriatric health care settings in France: the VESTA study.

BACKGROUND: Because of a lack of efficacy of influenza vaccination in elderly population, there are still numerous outbreaks in geriatric health care settings. The health care workers (HCW) flu vaccination is known to get herd immunity and decrease the impact of influenza in elderly population living in geriatric health care settings. However, the rates of vaccinated HCWs are still low in France. The French Geriatric Infection Risk Institute (ORIG) performed the VESTA study, a three-phase multicentre to identify factors limiting vaccination in HCWs, and to develop and implement active programs promoting HCWs influenza vaccination. OBJECTIVES: To implement multicenter programs to enhance HCW influenza vaccination. DESIGN: It was a cluster randomised interventional studies. SETTING: 43 geriatric health care settings (GHCSs), long term care and rehabilitation care settings in France. PARTICIPANTS: 1814 Health care workers from 20 GHCSs in the interventional group and 2,435 health care workers in 23 GHCSs in the control group. INTERVENTION: After the failure of a first educational program giving scientific information and. tested during the 2005-06 flu season in 43 HCSs, a second program was designed with the help of marketing experts, one year after Program 1. The objectives were to involve HCWs in the creation of "safety zones", and to give personal satisfaction. Program 2 was tested during the 2006-07 season. 20 of the 24 HCSs from the Program 1 cluster were included in the Program 2 cluster (1,814 HCWs), and 16 of the 19 HCSs from the Control 1 cluster, plus 7 new HCSs with interest in participating, were included in the Control 2 cluster (23 HCSs; 2,435 HCWs). MEASUREMENTS: The efficacy of each program was assessed by calculating and comparing the percentage of vaccinated HCWs, from all HCSs taken together, in the program and control clusters. RESULTS: Program 1 failed to increase the HCW vaccination coverage rate (VCR) (Program 1: 34%; Control 1: 32%; p > 0.05),). Program 2 increased the VCR in HCWs (Program 2: 44%; Control 2: 27%; Chi2 test, p < 0.001) regardless their occupational group but only in the non previous vaccinated subgroup. CONCLUSIONS: In geriatric health care centres in France, an active multicenter program giving personal satisfaction and taking into account the profile of non-vaccinated HCWs was more effective in promoting flu vaccination than a scientifically factual information program. HCW involvement is required in program implementation in order to avoid rejection of top-down information.

Role of catecholamines in glucagon-induced thermogenesis.

The present work was undertaken in order to investigate whether the observed thermogenesis following glucagon injection requires the participation of catecholamines. Our experiments aim at studying the effects of intraperitoneal injection of glucagon on metabolic rates, plasma catecholamine and fuel metabolites in guanethidine-treated ducklings reared at thermoneutrality (25 degrees C). The chronic guanethidine treatment induced a marked decrease in catecholamines levels in peripheral tissues (heart, muscle and intestine) but not in adrenals. At thermoneutrality, intraperitoneal injection of glucagon had lower thermogenic effects in guanethidine-treated compared to control ducklings. Glucagon injection elicited a concomitant increase of plasma norepinephrine, metabolic rate and energy metabolites in control ducklings, whereas in guanethidine-treated ducklings, the plasma catecholamines and metabolic rate did not undergo any consistent change. The thermogenic action of glucagon in birds involves at least the mobilization of lipids and catecholaminergic system stimulation.

Responsiveness of plasma catecholamines to intracerebroventricular injection of glucagon in Muscovy ducklings.

Recent investigations have demonstrated a modulatory action of glucagon on shivering via the central nervous system in ducklings. The aim of this study was to investigate the effects of intracerebroventricular injection (i.c.v.) of glucagon on metabolic rates (MR) and plasma catecholamines in control ducklings (TN) and in ducklings exhibiting nonshivering thermogenesis after chronic glucagon treatment: (GT). At thermoneutrality (25 degrees C, Ta), i.c.v. injection of glucagon had no thermogenic effects in TN and GT ducklings. At cold (+4 degrees C, Ta), i.c.v. glucagon injection elicited a concomitant decrease of plasma norepinephrine (NE) and MR in TN ducklings, whereas in GT ducklings, the plasma catecholamines and the MR remained unchanged. These results indicate that glucagon treatment rendered the catecholaminergic system of GT ducklings insensitive to cold or i.c.v. glucagon injection.

Involvement of the catecholaminergic system in glucagon-induced thermogenesis in Muscovy ducklings (Cairina moschata).

Physiological studies have shown that glucagon is a potential mediator of nonshivering thermogenesis (NST) in birds. The present work was undertaken in order to investigate whether the observed thermogenesis results from a direct action of glucagon on avian thermoregulatory mechanisms or in fact requires the participation of other agents such as catecholamines. Our experiments were performed using cold-acclimated (CA) ducklings which developed muscle NST. A comparison was made with thermoneutral (TN) ducklings of the same age. Our principal results showed that: (1) at ambient temperature (25 degrees C), circulating norepinephrine (NE) was markedly decreased in CA ducklings (-42%), while circulating epinephrine (E) did not undergo any consistent change; (2) in CA and TN ducklings, an intraperitoneal injection of glucagon (360 microg x kg(-1)) was followed after 10 min by prominent lipolysis and a large increase in circulating NE (4- to 6-fold) and E (14- to 17-fold), which was sustained for at least 1 h. The elevation of circulating NE was less pronounced in CA ducklings. The thermogenic action of glucagon in birds is probably indirect and involves at least the mobilization of lipids and sympatho-adrenal stimulation. The changes in peripheral noradrenergic activity during cold acclimation could be associated with adaptive changes leading to NST.
