Epidemiology of poisoning in Syria (1999 through 2020).

INTRODUCTION: Acute poisoning is a significant international public health issue and one of the leading causes of death in the emergency department (ED). In the absence of any previous reports describing the poisoning profile in Syria, we present this study to assess the epidemiological and clinical characteristics of poisoning over 21 years. METHODS: We collected the data retrospectively from the Syrian Poisons Information Centre (SPIC) from January 1999 until December 2020. The data included patients who had accidental or non-accidental exposure to poisons, either by drugs, medicaments, and biological substances or substances chiefly nonmedicinal sources such as soaps and detergents, corrosive substances, pesticides, and other miscellaneous products. RESULTS: We collected the data of 120,972 poisoned patients, of whom 52.6% were females, and 47.4% were males. Aleppo governorate reported the highest number of poisoned cases (28.6%), followed by Damascus governorate (19.9%). The highest poisoning rates were recorded in 2020, 2014, and 2010. Pharmaceutical (37.0%) and animal (33.8%) sources were the most common causative agents. The oral route was the route of poisoning in 58.3% of patients, and 33.4% through the skin. The most common poison was scorpion stings 19.5% while the most common cause of death was organophosphates 15.7%. DISCUSSION: The differences in socioeconomic status, cultural habits, and agricultural and industrial activities between countries have led to a state of fluctuation regarding the most common poisoning agents. CONCLUSION: Damascus and Aleppo, the two major governorates in Syria, had the highest poisoning cases. Oral administration of pharmaceutical agents was responsible for most of the poisoning cases. The most common individual poison was the scorpion poison, while the top killer was organophosphates.

The FGF-21 genetic variants rs838133 and rs838145 are associated with high salt intake in the Emirati population.

Food predilection is linked to variants in the hepatokine "Fibroblast Growth Factor-21" gene (FGF21); with rs838133 linked to the sweet tooth in Caucasians. The effect of FGF21 variants on food intake is still unclear in other populations. A cohort of 196 healthy Emirati subjects was investigated [age: 30.34 ± 9.75yrs (44.4% males)]. The FGF21 rs838133 and rs838145 were genotyped. The daily intake was calculated based on a 61-item food frequency questionnaire. Multivariate analysis was performed using in house R script that implements two-way unsupervised hierarchical clustering to detect the association of the studied single-nucleotide polymorphisms (SNPs) and related SNPs in linkage disequilibrium, using data from the 1000 genome project. Both SNPs were in Hardy-Weinberg Equilaribium (HWE). BMI positively correlated with age (p = 0.002), but not with caloric intake. Salt intake was significantly higher in subjects homozygous (A: rs838133) and (G:rs838145),(p = 0.03 and 0.01, respectively). An interaction was observed between both SNPs; significantly associated with high salt intake. Using publicly available data, both SNPs fall within a region transmitted in Iberians which has a profile closely similar to Caucasians, but far from Chinese population. In conclusion, the minor alleles of FGF21 rs838145 and rs838133 are associated with high salt intake in Emiratis and may suggest neuro-metabolic link to dietary preference across different populations.

The FTO genetic variants are associated with dietary intake and body mass index amongst Emirati population.

BACKGROUND: The risk of obesity is determined by complex interactions between genetic and environmental factors. Little research to date has investigated the interaction between gene and food intake. The aim of the current study is to explore the potential effect of fat mass and obesity-associated protein gene (FTO) rs9939609 and rs9930506 single nucleotide polymorphism (SNP) on the pattern of food intake in the Emirati population. METHODS: Adult healthy Emirati subjects with Body mass index (BMI) of 16-40 kg/m2 were included in the study. Genotyping for FTO rs9939609(A>T) and rs9930506(A>G) was performed using DNA from saliva samples. Subjects were categorized according to the WHO classification by calculating the BMI to compare different classes. Dietary intake was assessed by a sixty-one-item FFQ that estimated food and beverage intakes over the past year. The daily energy, macronutrient, and micronutrient consumption were computed. RESULTS: We included 169 subjects in the final analysis (mean age 30.49± 9.1years, 57.4% females). The mean BMI of the study population was 26.19 kg/m2. Both SNPs were in Hardy Weinberg Equilibrium. The rs9939609 AA genotype was significantly associated with higher BMI (p = 0.004); the effect was significant in females (p = 0.028), but not in males (p = 0.184). Carbohydrate intake was significantly higher in AA subjects with a trend of lower fat intake compared to other genotypes. The odds ratio for the AA was 3.78 in the fourth quartile and 2.67 for the A/T in the second quartile of total carbohydrate intake, considering the first quartile as a reference (95% CI = 1.017-14.1 and 1.03-6.88, respectively). Fat intake was significantly lower in the FTO rs9930506 GG subjects. The presence of FTO rs9930506 GG genotype decreased the fat intake in subjects with FTO rs9939609 AA (p = 0.037). CONCLUSIONS: The results of this study highlight the interaction of the FTO risk alleles on the food intake in Emirati subjects. The FTO rs9939609 AA subjects had higher carbohydrate and lower fat intake. The latter was accentuated in presence of rs9930506 GG genotype.
