Ripe date fruits contain phenolic compounds which possess a high antioxidant activity. The current review was carried out to evaluate total phenolic content in ripe date fruits. Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) was followed during the review process. Relevant studies published from inception up to March 2019 were retrieved from three databases. Study selection was performed based on specific inclusion criteria. A total of twenty-two articles were selected and included in the present review. Data collected from these studies were organized, pooled, and analyzed using descriptive statistics. Total phenolic content means and medians have been reported for the collected ripe date fruit samples for each included study and pooled data. The results suggested that ripe date fruits contain a potent total phenolic content that can contribute mainly to their antioxidant properties.

The present study examined the phytochemical composition, antioxidant, antimicrobial properties, and molecular docking of different solvents extracts (methanol and water) of two medicinal plants, namely, Capparis spinosa L (CS) and Rumex nervosus (RN). Phytochemical analysis showed that total phenol, flavonoids, alkaloids, and vitamin C were significantly (P ≤ 0.05) higher in the methanolic extract of both plants than in other solvents. However, tannin content was significantly (P ≤ 0.05) high in the water extract for both plants. Chloroform and acetone extracts were significantly lower in phytochemicals than other solvents, therefore excluded in this study. GC–MS analysis showed one dominant compound in CS (isopropyl isothiocyanate) and two in RN (pyrogallol and palmitic acid). The antioxidant methods applied (DPPH, ABTS, β-Carotene/linoleic acid assay, and reducing the power) showed that the methanolic extract of CS exerted higher activity in methanolic extract but lower than that of BHA standard. The methanolic extract of both plants inhibited the bacterial pathogens when a minimum inhibitory concentration (MIC) method was applied, compared to water extract with RN-methanolic extract had a lower inhibition concentration than CS-methanolic extract. The molecular interactions study revealed that the palmitic acid and pyrogallol interacted with the receptors' active site. This work concluded that CS and RN showed a remarkable antioxidant and antibacterial effect with the high antimicrobial activity of RN extract.

Vascular endothelial cells have a critical role in the maintenance of cardiovascular function. Evidence suggests that endothelial function may be compromised under conditions of magnesium deficiency, which increases vulnerability to inflammation. Whole genome transcription analysis was used to explore the acute (24 h) effects of magnesium on human umbilical vascular endothelial cells (HUVEC) cultured in low (0.1 mM) or high (5 mM) concentrations. With low magnesium 2728 transcripts were differentially expressed compared to the 1 mM control cultures and 3030 were differentially expressed with high magnesium. 615 transcripts were differentially expressed under both conditions, of which only 34 showed a concentration-dependent response. Analysis indicated that cellular organisation and biogenesis and key cellular processes such as apoptosis were impacted by both low and high conditions. High magnesium also influenced protein binding functions, intracellular signal transduction, metabolic and catalytic processes. Both conditions impacted on stress-related processes, in particular the inflammatory response. Key mediators of calcium-dependent regulation of gene expression were responsive to both high and low magnesium conditions. The HUVEC transcriptome is highly sensitive to acute changes in the concentration of magnesium in culture medium. The findings of this study support the view that whilst inflammation is an important process that is responsive to magnesium, the function of the endothelium may be impacted by other magnesium-induced changes including maintenance of cellular integrity, receptor expression and metabolic functions. The high proportion of transcripts that did not show a concentration-dependent response suggests variation in magnesium may elicit indirect changes, possibly mediated by other ions.

Children with intellectual or developmental disabilities are susceptible to malnutrition. This systematic review was conducted to assess the nutritional status and dietary behaviors of children with intellectual or developmental disabilities in Saudi Arabia. The target population was children from Saudi Arabia aged 18 years or younger and diagnosed with intellectual or developmental disabilities. Appropriate research studies that were published from inception up to December 2023 were obtained and reviewed. The outcomes of interest, including anthropometric data, laboratory data, dietary intake data, and dietary behaviors data, were collected and organized in relevant tables. The methodological quality and bias risk for the involved studies were evaluated. Out of 286 screened articles, 31 research articles were selected. The review results show that the rates of overweight and obesity were significantly higher among children with intellectual or developmental disabilities compared to typically developing children. The laboratory data revealed that they were more likely to have nutritional deficiencies. Low intake of energy, protein, and several micronutrients is frequently reported among them. Moreover, they are anticipated to have unhealthy dietary behavior. In conclusion, the findings suggested that children with intellectual or developmental disabilities were at higher risk of malnutrition including deploying obesity and nutritional deficiencies. Healthy and balanced nutrition that considers dietary requirements and food preferences is critical to maintaining the optimal development of these children. This review could invite researchers and policy-makers in Saudi Arabia to put more effort into integrating individuals with disability into the healthcare system and community. Further research is required to determine the types of intervention measures that can be taken to reduce the risk of malnutrition. Additional action is needed to monitor the implementation of national policies and programs that target this part of society.

Purpose: The purpose of this study is to investigate the effect of roselle flower extract and date palm pollen on the nutritional and sensory qualities of date palm spathe beverage (DPSB).Design/methodology/approach: The nutritional composition and sensorial quality of the date palm spathe-based beverage were evaluated. The product was fortified with different concentrations (1 per cent and 5 per cent) of roselle flowers and 1 per cent date palm pollen grains.Findings: Generally, fortification of the DPSB with roselle flowers only or the combination of roselle flowers and date palm pollen grains significantly affected the nutritional and sensory properties of the products. The total dissolved solids, turbidity and total contents of proteins; fats; carbohydrates; vitamins A, E and C; iron; nickel and copper were highest in the DPSB fortified with a mixture of 1 per cent roselle flower extract and 1 per cent pollen grains and lowest in the DPSB supplemented with 1 per cent roselle flower extract. The manganese and selenium contents were both highest and lowest in DPSB supplemented with 5 per cent and 1 per cent roselle flower extract, respectively. Antioxidant activity was highest in DPSB supplemented with the 5 per cent roselle flower extract and lowest in unfortified DPSB. Boron, molybdenum and zinc contents were highest in unfortified DPSB. All sensory attributes were highest in both the unfortified DPSB and that fortified with 1 per cent roselle flower extract.Originality/value: While fortification with a combination of 1 per cent roselle flower extract and 1 per cent date palm pollen grains improved the nutritional quality of the DPSB, it negatively affected the sensory attributes of the products.

Globally, millions of children live with intellectual and developmental disabilities (IDD), which can raise the risk of malnutrition in children. Data from Saudi Arabia on school‐aged children with IDD remain limited. Therefore, this study aimed to determine the prevalence of malnutrition among school‐aged children with and without IDD in Saudi Arabia. This cross‐sectional study was conducted during August–December of 2024 at the Child Development Center at University Hospital, Riyadh, Saudi Arabia. School‐aged children (5–17 years) with clinician‐diagnosed autism spectrum disorder (ASD), Down syndrome (DS), attention deficit/hyperactivity disorder (ADHD), or cerebral palsy (CP) and age‐matched children without IDD were recruited. Weight and height were measured, and body mass index (BMI) was calculated. WHO Growth Reference 2007 (5–19 years) was used to generate BMI‐for‐age z‐scores (BAZ) and height‐for‐age z‐scores (HAZ) using WHO AnthroPlus; weight‐for‐age z‐scores (WAZ) were computed only for children aged ≤ 10 years. Malnutrition was defined as undernutrition (thinness and/or stunting and/or underweight) and/or overnutrition (overweight and/or obesity). A total of 168 children participated (IDD, n = 68; non‐IDD, n = 100). Overall malnutrition prevalence was similar in children with and without IDD (47% vs. 48%; risk ratio [RR] 0.98, 95% CI 0.71–1.36; p = 0.905). Overnutrition was more common than undernutrition in both groups (IDD: 29% overnutrition vs. 25% undernutrition; non‐IDD: 32% vs. 28%). Although overall prevalence was comparable, marked heterogeneity was observed across IDD subtypes (malnutrition: DS 90%, ADHD 50%, CP 48%, ASD 24%; χ 2 (3) = 12.02, p = 0.007; FDR‐adjusted q = 0.022). Concurrent stunting and overweight/obesity (individual‐level double burden) was observed in 12% of non‐IDD children and 7% of children with IDD. In conclusion, nearly half of this hospital‐based sample of Saudi school‐aged children had evidence of malnutrition, with overnutrition exceeding undernutrition. While overall malnutrition prevalence did not differ between children with and without IDD, the distribution across IDD subtypes was clinically meaningful. Routine growth monitoring and targeted nutrition support are needed in both clinical and school settings.
