Le pluralisme juridique au Liban

Né sur la rive orientale de la Méditerranée, à la fin du quatrième millénaire avant notre ère, le Liban a toujours constitué, par sa situation géographique et la richesse spirituelle et culturelle des populations qu’il a successivement ou simultanément accueillies, un trait d’union entre l’Orient et l’Occident. La diversité des origines de sa population en fait aujourd’hui un creuset vivant de cultures et de religions. Son statut d’État moderne, mais sous mandat, lui a été conféré, le 1er sep..

Influence of Sarcopenia on Bone Health Parameters in a Group of Elderly Lebanese Men

International audienceSarcopenia is a disease characterized by the loss of muscle mass and strength. The aim of the current study was to explore the influence of sarcopenia on bone health parameters in a group of elderly Lebanese men. To do so, we compared bone health parameters (Bone Mineral Content (BMC), Bone Mineral Density (BMD) and femoral neck geometry indices) in a group of elderly men with sarcopenia and a group of elderly men with normal Skeletal Muscle mass Index (SMI). 23 sarcopenic men (SMI 7 kg/m 2) participated in our study. Body composition and bone variables were measured by Dual-energy X-ray Absorptiometry (DXA). DXA measurements were completed for the Whole Body (WB), Lumbar spine (L1-L4), Total Hip (TH) and Femoral Neck (FN). Hip geometry parameters including Cross-Sectional Area (CSA), Cross-Sectional Moment of Inertia (CSMI), section modulus (Z), Strength Index (SI) and Buckling Ratio (BR) were derived by DXA. Age and height were not significantly different between the two groups. Weight, Body Mass Index (BMI), lean mass, fat mass, appendicular lean mass, SMI, WB BMC, TH BMD, FN BMD, CSA, CSMI and Z were significantly higher in non-sarcopenic men compared to sarcopenic men. In the whole population , lean mass was the strongest determinant of bone health parameters. After adjusting for lean mass, there were no significant differences regarding bone health parameters between the two groups. In conclusion, the present study suggests that sarcopenia negatively influences bone health parameters in elderly Lebanese men

Relationships Between Muscular Power and Bone Health Parameters in a Group of Young Lebanese Adults

International audienceThe aim of the current study was to explore the relationships between lower limb muscular power and bone variables (bone mineral content (BMC), bone mineral density (BMD), hip geometry indices and trabecular bone score (TBS)) in a group of young Lebanese adults. 29 young Lebanese men and 31 young Lebanese women whose ages range between 18 and 32 years participated in this study. Body weight and height were measured, and body mass index (BMI) was calculated. Body composition and bone variables were measured by DXA. DXA measurements were completed for the whole body (WB), lumbar spine (L2–L4), total hip (TH) and femoral neck (FN). Hip geometry parameters including cross-sectional area (CSA), cross-sectional moment of inertia (CSMI), section modulus (Z), strength index (SI) and buckling ratio (BR) were derived by DXA. Trabecular bone score was also derived by DXA. Horizontal jump (HJ), vertical jump, vertical jump maximum power, force-velocity maximum power and 20-m sprint performance were measured or calculated by using validated fitness tests. In men, fat mass percentage was negatively correlated to TH BMD, FN BMD, CSA, CSMI, Z and SI. In women, weight, BMI, lean mass and fat mass were positively correlated to WB BMC, CSMI and Z. Regarding physical performance variables, horizontal jump performance and force-velocity maximal power were positively correlated to TH BMD, FN BMD, CSA and Z in men. Vertical jump maximal power was positively correlated to WB BMC in women. 20-m sprint performance was negatively correlated to FN BMD, CSA, Z and SI in men. In conclusion, the current study suggests that force-velocity maximum power is a positive determinant of BMD and hip geometry indices in men but not in women

Anemia among children and women in the Eastern Mediterranean Region: A Technical Guide

Anemia, a condition defined by deficiency in the size or number of red blood cells (RBCs), or a lower-than-normal level of hemoglobin within the RBCs, is a multifactorial condition whereby numerous factors may contribute to its development. The main factors include inadequate nutrition, poor nutrient absorption, deficiencies in essential micronutrients, nutritional interactions, infections, inflammation, chronic diseases, gynecological factors, heavy menstrual cycles, hemorrhage, pregnancy complications, family history of anemia and inherited disorders affecting RBCs. Anemia remains a significant public health concern, with the most vulnerable being children under five, specifically infants and young children below the age of 2 years, adolescent girls, women of reproductive age (WRA) and pregnant women. While symptoms of anemia vary depending on its severity, common symptoms include fatigue, dizziness, shortness of breath, chills at the extremities (hands and feet), headache, palpitations, decreased physical endurance, inadequate nutrition, and reduced productivity. Anemia predominantly affects low-income and middle-income countries with the heaviest burden, specifically populations residing in rural areas, economically disadvantaged households, and those lacking formal education. In 2019, the World Health Organization (WHO) estimated that approximately 40% of under five children, 37% of pregnant women, and 30% of WRA (15–49 years of age) worldwide are anemic. In the Eastern Mediterranean Region (EMR), the prevalence among under five children ranged between 11.9% and 79.5%. Among WRA, the prevalence ranged from 23.7% to 61.5%, while the prevalence among pregnant women was estimated between 19.1% and 57.5% in countries of the region. When the prevalence was assessed based on income, data from the region showed that in general, as income increased, the prevalence of anemia, and subsequently its severity, decreased, even though some exceptions were present in few countries. When the severity of anemia was assessed, the majority of EMR countries fell into the moderate category for anemia, with a prevalence rate ranging between 20% and 39.9% among under five children, WRA and pregnant women. The majority of EMR countries are therefore off track when compared with the World Health Assembly (WHA) global target of reducing anemia by 50% among WRA in 2025. The management and prevention of anemia should be specific in targeting the underlying nutritional and non-nutritional causes of anemia. This includes following a healthy, nutritious and diversified diet; improving infant feeding practices and promoting exclusive breastfeeding; considering supplementation if necessary; implementing food fortification policies; implementing nutrition education and awareness programs; enforcing food security and ensuring adequate access to a healthy, nutritious and diversified diet, across the population; targeting non-nutritional causes of anemia through specific programs pertinent to malaria, HIV, tuberculosis, soil-transmitted parasitic worms, genetic blood disorders, water, sanitation and hygiene (WASH), environmental and social aspects, delayed cord clamping, birth spacing, and menstrual bleeding and hemorrhage. Therefore, multifaceted, holistic and comprehensive approaches to address the key contributors to anemia are a must, along with frequent monitoring, evaluating and impact assessment. Key recommendations highlighted in the regional expert consultation 2023, on prevention and management of anemia in the EMR, focused on the following: defining a holistic approach; advocacy, coordination and communication; nutrition, dietary habits and preferences; nutrition education; providing support; school-based approaches; data collection, assessment, revision and monitoring; data quality/reporting and analysis; and coverage of interventions

Relations Between Maximal Half Squat Strength and Bone Variables in a Group of Young Overweight Men

International audienceThe purpose of this study was to investigate the relationships between maximal half-squat strength and bone variables in a group of young overweight men. 76 young overweight men (18 to 35 years) voluntarily participated in this study. Weight and height were measured, and body mass index (BMI) was calculated. Body composition, bone mineral content (BMC) and bone mineral density (BMD) and geometric indices of hip bone strength were determined for each individual by Dual-energy X-ray absorptiometry (DXA). Maximal half-squat strength was measured by a classical fitness machine (Smith machine) respecting the instructions of the national association of conditioning and muscular strength (NCSA). Maximal half-squat strength was positively correlated to WB BMC (r = 0.37; p < 0.01), WB BMD (r = 0.29; p < 0.05), L1–L4 BMC (r = 0.43; p < 0.001), L1–L4 BMD (r = 0.42; p < 0.001), TH BMC (r = 0.30; p < 0.01), TH BMD (r = 0.26; p < 0.05), FN BMD (r = 0.32; p < 0.01), FN cross-sectional area (CSA) (r = 0.44; p < 0.001), FN cross-sectional moment of inertia (CSMI) (r = 0.27; p < 0.05), FN section modulus (Z) (r = 0.37; p < 0.001) and FN strength index (SI) (r = 0.33; p < 0.01). After adjusting for lean mass, maximal half-squat strength remained significantly correlated to WB BMC (p = 0.003), WB BMD (p = 0.047), L1–L4 BMC (p < 0.001), L1–L4 BMD (p < 0.001), TH BMC (p = 0.046), FN BMD (p = 0.016), FN CSA (p < 0.001), FN Z (p = 0.003) and FN SI (p < 0.001). The current study suggests that maximal half-squat strength is a positive determinant of BMC, BMD and geometric indices of hip bone strength in young overweight men
