Introduction: Low prevalence of exclusive breastfeeding in the Arab world is concerning and suboptimal breastfeeding is a leading child health risk factor in several Arab States. Breastfeeding education has the capacity to improve breastfeeding knowledge and practice, thus positively impacting infant and maternal health. The purpose of this review is to identify and examine the impact of breastfeeding promotion interventions across the Arab world. Method: A scoping review of the literature was conducted across seventeen databases for relevant publications published through October 2021 to find studies in Arab countries, that involved breastfeeding as an intervention component. Twenty-one articles met inclusion criteria and were reviewed. Results: Individual and community based educational interventions offer the opportunity to positively impact the knowledge, attitudes, and practices of breastfeeding in new mothers in Arab countries. Increased breastfeeding has the potential to lead to improved neonate and maternal health. In addition to significant benefits found across individual and community-based interventions in a variety of Arab countries, there is also evidence that interventions that improve the knowledge of health care professionals and/or the practices of a health care system can contribute to subsequent increases in breastfeeding rates. Discussion: Breastfeeding education is a low-cost and high-impact public health tool that can impact infant and maternal health and potentially increase breastfeeding adherence in the Arab world. Significance: What is already known on this subject? Breastfeeding has major long-term effects on the health and development of children as well as women's health. Combined health systems and community interventions more than double exclusive breastfeeding rates globally. The most cost-effective ways to promote exclusive breastfeeding include counselling and supportive interventions in multiple settings. What this study adds? Multi-component educational and supportive interventions increase breastfeeding initiation and duration among mothers in the Arab world. The most successful interventions among Arab women include education as well as pre- and post-partum support. Education and training for health professionals on the importance of breastfeeding can have broad-reaching impact on improving breastfeeding rates. [ABSTRACT FROM AUTHOR]

Mahonia bealei is one of the important members of the genus Mahonia and Traditional Chinese Medicine (TCM). Several compounds isolated from this plant have exhibited useful biological activities. Polysaccharides, an important biomacromolecule have been underexplored in case of M. bealei. In this study, hot water extraction and ethanol precipitation were used for the extraction of polysaccharides from the stem of M. bealei, and then extract was purified using ultrafiltration membrane at 50,000 Da cut off value. Characterization of the purified M. bealei polysaccharide (MBP) was performed using Fourier Transform Infrared Spectroscopy (FT-IR), along with Scanning Electron Microscopy (SEM), X-ray crystallography XRD analysis and Thermal gravimetric analysis (TGA). The purified polysaccharide MBP was tested for antioxidant potential by determining its reducing power, besides determining the DPPH, ABTS, superoxide radical, and hydroxyl radical scavenging along with ferrous ion chelating activities. An increased antioxidant activity of the polysaccharide was reported with increase in concentration (0.5 to 5 mg/ml) for all the parameters. Antimicrobial potential was determined against gram positive and gram-negative bacteria. 20 µg/ml MBP was found appropriate with 12 h incubation period against Escherichia coli and Bacillus subtilis bacteria. We conclude that polysaccharides from M. bealei possess potential ability of biological importance; however, more studies are required for elucidation of their structure and useful activities.

Cucumber is a highly perishable fruit, that can easily suffer from water loss, condensation, shriveling, yellowing and decay. The present investigation aim was to extending the shelf-life of cucumber using eco-friendly sodium tripolyphosphate and nano-material. Decay; hardness; succinate dehydrogenase activity (SDH); condensation and shriveling rates; and visual quality assessments of cucumbers fruits were evaluated during 21 days of storage period at 10 °C. There was a slight incidence of decay among (Chitosan/Titanium Dioxide Nanoparticles) CS-TiO2 and (Chitosan/Titanium Dioxide Nanoparticles/Sodium Tripolyphosphate) CS-TiO2-STP samples, which reported the lowest decay incidence 2.21% in CS-TiO2, while CS-TiO2-STP did not show any decay at end of storage period. CS-TiO2-STP recorded the lowest value in SDH activity 0.08 ∆OD min−1 mg protein−1. Very slight hardness, water condensation, and shriveling were detected in CS-TiO2 samples, while CS-TiO2-STP was the lowest compared with other SC samples and control. In general, CS-TiO2-STP treatment was found most potential to enhance the postharvest shelf life of cucumber throughout the storage period up to 21 day. [ABSTRACT FROM AUTHOR]

White button mushrooms are greatly high perishable and can deteriorate within a few days after harvesting due to physicomechanical damage, respiration, microbial growth of the delicate epidermal structure. For that reason, the present research work was applied to evaluate the effect of chitosan combination with nano-coating treatments on physicochemical parameters and microbial populations on button mushrooms at chilling storage. Nano coating with the addition of nisin 1% (CHSSN/M) established the minimum value for weight loss 12.18%, maintained firmness 11.55 N, and color index profile. Moreover, O2% rate of (CHSSN/M) mushrooms was the lowest at 1.78%; while the highest rate was reported for CO2 24.88% compared to the untreated samples (Control/M) on day 12. Both pH and total soluble solid concentrations increased during storage. Results reported that the (CHSS/M) mushroom significantly (P < 0.05) reduced polyphenol oxidase activity (24.31 U mg−1 Protein) compared with (Control/M) mushrooms that increased faster than the treated samples. (CHSSN/M) treatment was the most efficient in the reduction of yeast and mold, aerobic plate microorganisms (5.27–5.10 log CFU/g), respectively. The results established that nano-coating film might delay the aging degree and accompany by marked prolongation of postharvest mushroom freshness. [ABSTRACT FROM AUTHOR]

Agaricus bisporus is an edible fungus with a limited shelf life due to high moisture loss, browning, respiration, self-dissolve, lack of physical protection, rotting, and microbial attack. Mushrooms have been coated with nisin, nano-silica, and chitosan films in order to extend the shelf life, preserve quality and oxidation activities. The results showed that treating the mushrooms with chitosan and nano-silica (CH-AN-SILICA) increased superoxide dismutase activity (SOD—6.53 U kg−1), total phenolic content (TPC—0.39 g kg−1), and malondialdehyde content (MDA—1.63 µmol kg−1). CH-AN-SILICA treatment exhibited the highest scavenging against 2,2-Diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radicals. While, CH-AN-SILICA with the addition of nisin as an antimicrobial agent preserved almost the reactive oxygen species such as hydroxyl radicals (OH—0.33 µmol g−1), superoxide anion (O2•−—0.271 mmol s−1 kg−1), and hydrogen peroxide (H2O2—21.54 µmol g−1). Besides, both CH-AN-SILICA and CH-AN-SILICA/N enhanced the catalase (CAT) activity and reduced the respiration rate. The results indicated that the combination of nisin, nano-silica, and chitosan coating films was effective in providing a longer storage life with acceptable quality in mushrooms.

Chitosan coating (B/CH) in addition with nano-material films as silicon (B/CH/Nano-SiO2) and titanium (B/CH/Nano-TiO2) dioxides were developed and applied to detect potential changes on fresh blueberry fruits in commercial storage temperature. Physical, mechanical parameters (weight loss, decay rate, colour index and firmness), phytochemical contents (ascorbic acid, acidity, soluble solids concentration, titratable acidity, and repining index), phenolic enzymes (peroxidase and polyphenoloxidase), pigments (anthocyanin) and microbiological analysis (mesophilic aerobic, yeasts and molds populations) were detected every other day until the end of the experiment. Nano-coating based on (Nano-TiO2) established the most suitable values for weight loss (2.22%), titratable acidity (0.45% citric acid), and repining index. (B/CH/Nano-TiO2) reported a gradual increase in polyphenoloxidase and peroxidase enzyme activities (659.45 U/min g) and (20.39 U/min g), respectively. While, (B/CH/Nano-SiO2) established the slightest change in acidity (2.61), anthocyanin (105.19 cyanidin-3-O-glucoside mg/100 g FW) and minimized the growth of mesophilic aerobic, yeasts, and molds populations (3.73–3.98 log CFU/g), respectively. (B/CH) films maintained lightness (6.80% loss) and recorded the highest ascorbic acid content (7.34 g/100 g FW). Therefore, chitosan nano-material films can maintain nutrients and control the microbial growth for extending the shelf life of fresh blueberry fruits. [ABSTRACT FROM AUTHOR]

Non-communicable diseases (NCD) related to inadequate nutrition are prevalent in economically transitioning countries such as the Arab region. The westernized diet is recognized as a leading trend and the UN General Assembly is focused on the prevention and control of NCD. Due to the rapid transitions in diet and physical inactivity occurring in the Arab region, revising public health dietary strategies, guidelines, and policies to reduce the burden of NCD is needed. This article presents existing literature on food label use in the Arab region as a response to the problem. The primary objective was to locate, review, and summarize peer-reviewed studies on how and why consumers use food labels in Arab countries. An integrative review of the related literature was conducted with no delimiting time frames. The authors applied search strategies to eight academic databases which produced 32 peer-reviewed articles. Seventeen were removed due to inconsistent scope and focus. Awareness of and nutrition knowledge about food labeling emerged as a primary theme. Education, household income, and age were secondary themes and predictor variables. Nutrition food labels as a population-based strategy can influence individual behavior change and potentially improve population health. These outcomes depend on the consumer's ability to understand nutrition labels and properly apply information. Themed recommendations included standardization of food labeling policies, consumer education on food labeling, and public health efforts to develop a detailed understanding of regional populations prior to health promotion strategy development. Enabling informed food selection and reinforcing healthy dietary intake can help prevent NCD and support individual and population health. [ABSTRACT FROM AUTHOR]
