Multifactorial hypovitaminosis D among women in the South-East Oases of Morocco

This study assessed the vitamin D status among women in South-East Oases of Morocco. Two hundred thirty-three healthy volunteer women were recruited at five urban and rural health centers. Hypovitaminosis D is very common in this region and correlated to age, monthly income, skin color, daily sun exposure, BMI, and body fat percentage.

PURPOSE

This study assessed the vitamin D status among women in the Draa-Tafilalet region and its relationship with clinical, anthropometric, and behavioral parameters.

METHODS

The study was carried out with 233 women in consultation at five urban and rural health centers in the South-East region of Morocco. The data collected relate to age, monthly income, educational level, BMI, body fat percentage, daily sun exposure, physical activity level, veil wear, and skin color. The plasma determination of vitamin D was measured by immunofluorescence. Statistical analyses were performed using Python and Jamovi.

RESULTS

The median 25(OH)D plasma concentration was 9.95 ng/mL (IQR: 8-13.18). A total of 50.64% of women had 25(OH)D levels below 10 ng/ml and 47.21% had levels between 10 and 30 ng/mL. Statistical tests showed an association between hydroxyvitamin D plasma levels and age (r =  - 0.139; p = 0.034), monthly income (p = 0.001), BMI (r =  - 0.200; p = 0.002), body fat percentage (r =  - 0.131; p = 0.049), daily sun exposure (r = 0.165; p = 0.012), and skin color (p < 0.001). Binomial logistic regression showed that darker skin was associated with vitamin D deficiency (< 10 ng/mL). It also showed that high income and longer sun exposure could be protecting factors against vitamin D deficiency.

CONCLUSION

The plasma concentrations of vitamin D in women in the Draa-Tafilalet region were low compared to expected results for a high sunshine time area.

Effects of COVID-19 home confinement on musculoskeletal health and physical performance in a cross-sectional study: results of the COVID-19 era online survey

Introduction

the global pandemic of COVID-19 is the unique health crisis, the populations were exposed to situations of unprecedented confinement, this represents a major public health challenge, with a high risk of developing musculoskeletal disorders. The objective of the present work is to identify the potential effects of sedentary behavior on musculoskeletal health and physical performance.

Methods

after two months of confinement a survey was uploaded and shared on Google's online survey platform. Two research laboratories, University Moulay Ismail, University Ibn Tofail, promoted the survey which was developed on the basis of two questionnaires: the French version of the Nordic questionnaire musculoskeletal disorders and the French version of the Global Physical Activity Questionnaire (GPAQ).

Results

out of 384 respondents, 209 (54.4%) were females 124 (32.3%) were between 30-49 years old (6.8%) and 123 (32%) had an underweight and overweight levels, respectively. One hundred and thirty-nine 139 (36.2%) reported sitting more than eight hours. The results of our survey show that many of our respondents had developed some sort of musculoskeletal pain during the confinement. One hundred and sixty two (42.2%) reported to have pain in the lower back region, 108 (28.1%) of participants reported to have pain in the neck region, 93 (28.2%) in the shoulder region, 97 (25.3) - in the upper back region and more women than men reported musculoskeletal pain in more than five regions. The results of our survey also show that 322 (83,9%) of the participants, after two months of confinement, were unable to do high intensity exercises for at least 10 min per day in their usual daytime activity, the prevalence of musculoskeletal pain differed across categories of body mass index (BMI) between males and females, (p<0.05).

Conclusion

the results of this study show the existence of musculoskeletal disorders and deterioration in physical performance and strongly recommend the urgent implementation of prevention and remediation interventions.

Adherence to the Mediterranean diet of school-age children in Moroccan oases, Draa-Tafilalet Region

Background

Dietary patterns, eating behaviour and lifestyle are changing in Morocco. It would be interesting to identify and evaluate this transition in its Mediterranean context.

Aims

To assess adherence to the Mediterranean diet (MedDiet) and analyse associated factors in school-age children living in oasis environments.

Methods

A cross-sectional survey was conducted among 3684 school-age children between May 2015 and November 2017 in Tafilalet Oasis. The mean age was 9.81 (2.13), 51.3% were girls, and 62.7% were from urban areas. Participants were recruited from public primary schools. Adherence to the MedDiet was evaluated by Mediterranean Diet Quality (KIDMED) index. Socioeconomic characteristics and anthropometric measurements were obtained.

Results

Only 2.12% had a poor KIDMED index, 57.9% had an average index and 39.98% had a high index. Maternal ethnicity was associated with degree of adherence to the MedDiet. Poor adherence was seen in 2.17% of urban participants compared with 2.04% of rural participants. Participants with high income were more likely to have good adherence to the MedDiet. Low levels of parental education were more likely to result in higher levels of poor adherence. There was no significant correlation between body weight and KIDMED index.

Conclusions

Most of the study population had medium to good adherence to MedDiet, but low KIDMED index was observed. Interventions and strategies should be devised for preserving and promoting healthy eating habits in this target population.

[Prevalence of obesity and overweight within the school environment in Tafilalet oasis, south-east of Morocco]

Introduction

L’obésité représente un sérieux problème de santé publique qui a un impact direct sur la santé physique et mentale des individus. L’objectif du présent travail est de déterminer la prévalence de l’obésité et du surpoids en milieu scolaire urbain et rural, chez une population infantile oasienne.

Méthodes

Nous avons entrepris une étude transversale descriptive au sein des établissements scolaires publics urbains et ruraux de l’oasis de Tafilalet. Nous avons recruté un échantillon représentatif de 3684 enfants scolarisés appartenant à 39 écoles publiques primaires.

Résultats

La moyenne d’âge était de 9,81 ± 2,13 ans. L’échantillon total s’est réparti en 1794 garçons (48,70%) et 1890 filles (51,30%). Deux mille trois cent neuf appartenant à l’urbain (62,70%) et 1375 au rural (37,30%). Selon les références de l’organisation mondiale de la santé, notre étude a révélé un taux d’obésité de 1,9% et 10,8% pour le surpoids. L’obésité et le surpoids n’étaient pas significativement associés avec le sexe des enfants.

Conclusion

La prévalence de l’obésité dans l’oasis de Tafilalet est inférieure aux données nationales et internationales, le mode de vie et les habitudes alimentaires de cette population semblent être un facteur protecteur contre l’obésité et le surpoids.

Epidemiological Profile of Drug Overdose Reported in South-East Morocco from 2004 to 2016

Background

Drug overdose, either accidental or intentional, is the most common cause of acute poisoning worldwide.

Objective

The aim of this study was to determine the epidemiological profile of drug poisoning recorded in the south east of Morocco and to identify the proportion of intentional versus accidental drug overdose.

Methods

This was an epidemiological study of 180 cases of medicinal poisoning registered with the Provincial Delegation of Health in Errachidia between January 2004 and December 2016. Information on demographic and drug overdose characteristics was obtained from the regional poison center. Drugs were categorized according to the anatomical therapeutic chemical (ATC) classification system.

Results

Adults were the most affected group, with a median age of 21 years and a sex ratio of three females to every male. Drug poisoning mainly occurred in urban areas (83% of cases). Regarding clinical signs, 55.2% of patients presented with digestive signs and 27.6% with neurological signs. Other signs were also present: respiratory (5.1%), combined neurological and digestive (4.5%), cardiovascular (3.8%), and general (3.8%). Women represented 88.9% of those who had intentionally overdosed and 64.3% of those who had unintentionally overdosed. Benzodiazepine derivatives and other related drugs were involved in 21.5% of cases of drug poisoning, with other drugs found in patients with drug overdose as follows: paracetamol 3.3%, ethinyl estradiol/levonorgestrel 5%, and cyproheptadine 1.6%.

Conclusion

Our results indicate that the number of reported cases of drug poisoning in south-east Morocco increased between 2004 and 2016. The intentional use of drugs in overdose was mostly  among adults, especially women. The drugs involved were predominantly psycholeptic drugs, followed by analgesics. Mortality was low, but investigation in a representative sample will show  the real severity and outcomes of drug overdoses.

Cardiovascular effect of Nigella sativa L. Aqueous Extract in Normal Rats

This study aims to evaluate the cardiovascular effect of Nigella sativa L. aqueous extract (NSAE) in normal rats. The in vivo experiment showed that the intravenous injection of NSAE at the doses of 50, 100 and 200 mg/kg of body weight produced a dose dependent reduction in the mean arterial blood pressure (MABP) (p<0.001) accompanied by a significant fall in heart rate (p<0.01). In the in vitro experiment, incubation of NSAE during 30 min caused a right shift of the contraction response curve of aortic ring to Norepinephrine (NE) with a reduction of the maximal contraction response (p<0.01). Endothelium destruction significantly reduced the vasorelaxant effect of NSAE at a dose of 30 mg/ml (p<0.01). Furthermore, Nitric oxide synthase inhibitor: Nω-Nitro-L-Arginine Methyl Ester (L-NAME) produced a significant reduction (p<0.01) of the in vitro vasorelaxant effect of NSAE at a dose of 30 mg/ml. We conclude that NSAE possess a rapid and dose dependent in vivo hypotensive effect in normal rats which may be probably due to the inhibition of parasympathetic tone. In isolated aortic ring, NSAE possess a potent inhibitor of contractile response to NE which may be probably due to an increase in the endothelial nitric oxide synthesis.

Analysis of food intake profile among women from the oasis of southeastern Morocco

Nutritional status is the best indicator of the global well-being of women and food intake is known to reflect a healthy diet. The aim of this study was to assess the influence of socioeconomic status on the food intake in women living in the southeastern oasis of Morocco by exploring their nutritional intake through 24-h dietary recall (n=387). Analysis of the relationship between food intake and the socioeconomic characteristics in women showed a positive correlation between daily vegetable, cereals, red and white meat intake and region of residence (p<0.001, p=0.005, p=0.001 and p=0.04 respectively). The number of persons living at home showed a positive significant correlation with the daily intake of vegetables (p=0.01) and beverage (p=0.004). For fish and cereals, a positive significant correlation with the occupation variable has been shown (p=0.04 and p<0.001 respectively). In addition, a positive correlation has been noticed between the daily intake of vegetables, cereals, white meat, and dairy product and family status in housing (p=0.03, p=0.02, p=0.03 and p=0.04 respectively). In conclusion, the level of education, family size and occupation influence the daily intake of food in this region.

Antidiabetic plants improving insulin sensitivity

BACKGROUND

Globally, the prevalence of diabetes mellitus is increasing at an alarming rate. This chronic pathology gravely troubled the human health and quality of life. Both insulin deficiency and insulin resistance are involved in the pathophysiology of diabetes mellitus. Moreover, insulin resistance is being diagnosed nowadays in a growing population of diabetic and obese patients, especially in industrialized societies. There are lots of conventional agents available to control and to treat diabetes, but total recovery from this disorder has not been reported up to this date. Plants provided a potential source of hypoglycemic drugs and are widely used in several traditional systems of medicine to prevent diabetes. A few reviews with less attention paid to mechanisms of action have been published on antidiabetic plants.

OBJECTIVES

The present review focuses on the various plants that have been reported to be effective in improving insulin sensitivity associated with diabetes.

KEY FINDINGS

In this work, an updated systematic review of the published literature has been conducted to review the antidiabetic plants improving insulin sensitivity and 111 medicinal plants have been reported to have a beneficial effect on insulin sensitivity using several in-vitro and in-vivo animal models of diabetes.

CONCLUSION

The different metabolic and cellular effects of the antidiabetic plants improving insulin sensitivity are reported indicating the important role of medicinal plants as potential alternative or complementary use in controlling insulin resistance associated with diabetes mellitus.
