Abstract
BACKGROUND Increased uptake of essential fatty acids during pregnancy through seafood and supplementation has been shown to positively correlate with gestational age and increased infant birth weight. We aimed to evaluate the effect of maternal dietary intake of essential fatty acids, supplementation on gestational period and infant birth weight. MATERIALS A literature search with the help of various databases such as PubMed, Google Scholar, Web of Science and Scopus was conducted. METHODS Original research articles and intervention-based studies, which involve an association between dietary intake and supplementation of essential fatty acids during full-term pregnancy on human infant birth outcomes and published from 2011 to 2021, were included. RESULTS In total, there were 21 intervention-based studies, including full-term pregnant women with or without existing comorbidities, which compared essential fatty acids in the form of dietary sources and supplementation with dietary counseling and with or without placebo. The intervention trials included in this review were conducted in developed and developing countries. Half of the pregnant women who enrolled in the study had comorbidities such as diabetes and hypertension, which might increase their risk of adverse maternal and infant birth outcomes. Most of the studies included in the review have reported a positive association between improvised dietary and supplementation intake of essential fatty acids with increased length of gestation, infant birth weight and other parameters such as head circumference, infant birth length and growth velocity. CONCLUSION Positive correlations were found between increased consumption of essential fatty acids in food sources and supplements with improvised infant birth weight and gestational period.

Abstract
Introduction:
Leptin hormone is produced by adipose tissue and soluble leptin receptor (sOB-R) influences leptin's free bioavailability. Obese individuals have unusually elevated leptin levels. Obesity influences insulin and other hormone levels and is a key risk factor for developing polycystic ovarian syndrome (PCOS) and mutations such as rs2025804 and G2548A (rs7799039). PCOS is a hormonal condition that affects females of reproductive age primarily. Although there is no known cause of PCOS, studies have linked it to various factors, including insulin resistance, obesity, and genetics. Till now, research indicates a substantial correlation between leptin and female reproductive hormones, and PCOS. Thus, the purpose of this study is to compile the available data for a better understanding of the link between leptin and its effect on female reproductive hormones and PCOS and to determine whether the leptin receptor polymorphism (LEPR) influences the start of PCOS.
Method:
Following a review of the relevant papers, it was determined that there is an association between leptin and female reproductive hormones such as luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol (E2), progesterone, and prolactin. It was observed that Gln223Arg (Q223R/rs1137101), Pro1019Pro (A3057G), Lys109Arg (K109R/rs1147100), rs2025804, and G2548A (rs7799039) are the LEPR polymorphisms associated with PCOS. Gln223Arg is the most frequently studied variant in the LEPR gene across populations.
Results:
Interestingly, different groups demonstrated varying relationships between leptin receptor polymorphisms and PCOS, particularly for Gln223Arg, which contains two alleles (G allele and A allele). The G allele was protective against PCOS in the Korean population but increased the frequency of PCOS in countries such as Bahrain, India, Iran, and Iraq. There was no significant difference between PCOS and controls with this polymorphism in places such as China, Turkey, Saudi Arabia, and Helsinki.
Conclusion:
To summarize, the association between multiple leptin receptor polymorphisms and PCOS is complex and varies by research region. There hasn't been much research done on the gene polymorphism "Gln223Arg" or the other polymorphisms. While certain research findings were notable, each came with its limitations. As a result, additional interventional studies, including precise criteria in bigger and more diverse groups, are required.

Abstract
Background: The school-based food and nutrition guidelines approach has the potential to combat undernutrition, overnutrition and micronutrient deficiencies among children and adolescents and set the foundation for a healthy adult lifestyle. Aim: To critically compare the Nutrition Friendly School Initiative (NFSI) of the World Health Organization (WHO) with the Food Safety and Standards Authority of India (FSSAI) and the Indian Academy of Pediatrics (IAP) guidelines to gauge the strengths and limitations. Additionally, to summarize the existing studies on implementing school food and nutrition guidelines. Methods: Policy documents of the above guidelines were critically evaluated, and narrative analysis was conducted. An electronic search was conducted for full-text research articles published in the English language between January 2007 to September 2021 in Science Direct, PubMed, Web of Science, and SCOPUS databases. Results: Upon critical comparison of the three guidelines, it was found that the NFSI and FSSAI guidelines shared similarities in many components and the FSSAI guidelines, if implemented adequately, could improve the school food environment and combat the triple malnutrition burden in India. After screening the articles based on the eligibility criteria, 11 studies were included in the preparation of the review. Studies reported partial or inadequate implementation and poor compliance with the guidelines or approach. A few studies identified barriers to guideline implementation. Conclusion: Implementation of school food and nutrition guidelines could improve the nutritional outcomes in children and adolescents. To sustain the effective implementation, adequate resources and preparedness are essential in low-and middle-income countries, including India.

Abstract
Inappropriate use of pesticides followed by unsafe handling practices to control the insect infestation among the farming groups in developing countries has resulted in a high exposure risk. The use of personal protective equipment is also negligible among Indian farmers due to their affordability to access the same. Very little research has been conducted to establish an exposure assessment procedure through dermal penetration of pesticide residues. Therefore, to quantify the contamination of pesticide residues through dermal exposure along with detailed field observations and pesticide management practices, a field study was conducted in Rangareddy district, Telangana, Southern India, to assess the dermal exposure based on dosimeter and hand washing methods. The analytical method was modified and validated in-house for performance parameters such as limit of detection, quantification, linear range, recovery, and precision. The potential dermal exposure values ranged from 0.15 to 13.45 μg, while a reduction was found in exposure levels as actual dermal exposure values ranged from 0 to 0.629 μg. Contamination through hand washing was the major contributor to overall dermal exposure. Statistical analysis revealed a significant difference in the exposed dermal regions of the leg and torso after the use of PPE. Penetration factor for each anatomical region and risk evaluation in terms of the Margin of Safety implies unsafe handling of pesticides. The findings of the present study confirm the increased exposure to organophosphate pesticides among operators and highlight the importance of the use of protective measures, especially among those that focus on dermal exposure mitigation.

Abstract
The present interventional study aimed to assess the impact of micronutrient supplementation on pesticide-residues concentrations, vitamins, minerals, acetylcholinesterase activity and oxidative stress among 129 farm children (9–12 years, n = 66 and 13–15 years, n = 63) involved in farming activities in Ranga Reddy district, Telangana, India. Our data showed the presence of five organophosphorus pesticide residues (chlorpyrifos, diazinon, malathion, monocrotophos, and phosalone) among children before-supplementation (both age-groups); while post-supplementation, only two pesticide residues (chlorpyrifos and diazinon) were detected indicating improved metabolic rate. Vitamin E, copper, magnesium and zinc levels were also improved in both the age-groups and manganese levels were significantly increased only among children of 13–15 years age group. Further, post-supplementation also showed an improvement in acetylcholinesterase activity and a decrease in lipid peroxidation among both the age groups of children. However, further research for ascertaining the ameliorating effect of micronutrients in preventing adverse effects of organophosphorus pesticides must be conducted.

Abstract
Background:
Cystic fibrosis is an autosomal recessive monogenic disease marked by a mutation in the cystic fibrosis transmembrane conductance regulator gene. Cystic fibrosis transmembrane conductance regulator gene mutations affect respiratory, digestive and reproductive functions and impede bicarbonate, bile acid and sweat secretion. Moreover, the current trend indicates that CF is no longer only a paediatric disease; but has progressively become a disease that also affects adults. This calls to address the condition with an appropriate nutraceutical approach.
Objective:
The study aims to find and collate nutritional targets in the management of Cystic Fibrosis.
Method:
Studies highlighting the benefits of nutrients or nutraceuticals in the management of Cystic Fibrosis were included from previously published research articles (1971 to 2020). Data including nutrients, nutraceuticals, study design, study model, sample size, age, dose and duration of the dose of the supplement were extracted from the studies included and explored to understand their role.
Results:
About 26 studies are being included in the present review. It was found that nutrient interventions comprising nutraceuticals including dietary fibre, proteins and amino acids (taurine, arginine, glutathione), fats (medium-chain triglycerides, polyunsaturated fatty acids (omega-3 fatty acids)), phytochemicals (apigenin, genistein, quercetin, curcumin, allicin, beta-carotene, Pulmonaria officinalis L, Epigallocatechin-3-gallate), micronutrients including vitamin A, vitamin D, vitamin K, magnesium and zinc in addition to antioxidants exhibit improvement in the symptomatic condition of cystic fibrosis patients.
Conclusion:
The advent of nutraceuticals in the food industry and studies indicating their promising benefits have paved a path for targeted therapies in cystic fibrosis.

Abstract
Background:
Nutrition plays an important role in fuelling an athlete for any sports event. The right nutrition helps in better performance and better recovery of an athlete. Nutraceutical, Omega-3 fatty acids have shown to have a potential contribution to their performance output, recovery and health/injury risk.
Objective:
The study aims to understand Omega-3 fatty acid supplementation and review the required dose and duration of the intervention sufficient to confer any potential health benefit.
Methodology:
The review was carried out using data from Google Scholar, PubMed databases. Studies were selected based on Omega-3 fatty acid supplementation to improve muscle functioning and inflammation. While those studies based on animal models, pregnant women or review articles were excluded from this review. Studies among athletes and non-athletes were selected and categorised.
Results:
Omega-3 fatty acid supplementation among the athletes has provided substantial evidence of their health benefits in peripheral neuromuscular conditions, anaerobic endurance, muscle soreness and reduced inflammation. It also hinted at the possible beneficial role of Omega-3 fatty acid in supplementation along with other sports beverages to help in muscle health. Among non-athletes, it was observed that Omega-3 fatty acids help decrease the levels of inflammatory markers among non-athletes also and it helps to improve muscle soreness after intense physical activity. Besides, it also helps in preventing muscle disuse atrophy which could help injured individuals.
Conclusion:
The dose range of 1.1 g to 7 g for 2 weeks to 4 months can help individuals, whether athlete or non-athlete, to show its effect in them.

Abstract
Background:
Annona Muricata is used as a folkloric herbal medicine as it has anticancer, antiproliferative and anti-tumorigenic properties. The extracts from various parts of the plant are considered therapeutic due to Annonaceous Acetogenin compounds which are an absolute boon to the versatility of the plant, paving the mechanistic pathways for its therapeutic potential.
Method:
Google Scholar and PubMed databases were reviewed with the main focus on availing information on Annona muricata and its anticancer effect on breast cancer.
Results and Discussion:
- An array of clinical investigations on the dosage of extracts on cell lines, animal models, and human trials provide confirmatory insights of A. muricata as a preventive and therapeutic measure for cancer. The extract when administered at different dosages shows a high cytotoxic effect on the cancer cells, mostly accounting for an IC50 of less than 1000µg/mL which is of significance.
Conclusion -:
Although high efficacy has been conclusive, assurance of the safety prior to commercialization is of significance. Investigations are required to define the origin and magnitude of side effects along with long-term safety for the enhancement of efficacy and optimum utilization of potential chemo-preventive properties of the plant for the curation of a nutraceutical intervention for cancer that surpasses the traditional medicine.

Abstract
Epidemiological studies suggest suppression of the lymphocytes function through cholinergic stimulation due to organophosphorus pesticide exposure. The study aimed to assess the alteration in the levels of immune cell phenotypes among farm women (FW) and farm children (FC) who were occupationally exposed to pesticides and age/gender-matched control subjects belonging to Rangareddy district (Telangana, India). A total of 129 FW, 129 FC and 268 age/gender-matched controls were recruited. Blood samples were collected from the selected subjects to estimate the levels of nine organophosphorus pesticide residues and CD (CD3+, CD4+, CD8+, CD16+ and CD19+) cell markers using LC-MS/MS and flow cytometry, respectively. Independent t-test analysis was conducted to compare the immune cell phenotypes between exposed and control groups. Spearman's rank correlation test was further carried out to identify any possible correlation between the pesticide residues and CD markers. The mean percentage for CD4+, CD8+ and CD16+ was found to be significantly low, while for CD19 + itwas significantly high in the FW as compared to the CW group (p < 0.01). Further, the residues of chlorpyrifos and monocrotophos among FW were found to be significantly correlating with the mean percentages of CD19+ and CD8+ markers, respectively. The cell marker subsets of CD4+ and CD8+ were significantly low in FC children 9-12 years and 13-15 years age groups, respectively (p < 0.05). Also, these levels were significantly correlating with the residues of malathion and monocrotophos. The present study could indicate an alteration in the lymphocytes' subpopulations, which may thereby infer the toxicity in the first phase assessment of immunotoxicity. Therefore, further studies may be conducted to understand the suspected pesticides' mechanism along with various other factors in causing immune suppression coupled with nutritional and other related disorders.

Abstract
Nutritional status plays a major role in determining the possible adverse health outcomes due to pesticide toxicity. The objective of the present study was to assess the organophosphorus pesticide residue levels among farm women (FW) (24-45years) and farm children (FC) (9-12 and 13-15years) belonging to the Rangareddy district (Telangana, India) along with their micronutrient status, inhibition of acetylcholinesterase activity, and oxidative stress levels. Residues of Chlorpyrifos, Diazinon, Malathion, Monocrotophos and Phosalone were found in the serum samples of FW and FC along with significantly low levels of vitamins and minerals. Inhibition of AChE activity was observed in FW and FC and altered oxidative stress parameters among FW. Correlation studies have found significant associations between the pesticide residues, micronutrients and antioxidant enzymes. The study suggests an association between pesticide exposure coupled with micronutrient deficiency, induced AChE inhibition, and oxidative stress.

Abstract
Amid growing concern about the adverse effects of pesticides, a questionnaire-based cross-sectional study was conducted to evaluate farmers' knowledge on pesticides handling. Results of in-depth surveys (n = 217) with field observations revealed that participants had a mean 18 years of farming experience and knapsack-sprays were used for spraying. About 99% were not using any personal-protective-equipments during mixing, loading, application operations. Over 80% reentered the treated farms within two-days of application without following safety protocols and 39% admitted unsafe disposal of empty containers of pesticides. Statistical-analysis revealed a significant association between participant's pesticide handling practices and self-reported morbidity symptoms (p < 0.05). Despite awareness of toxicity, participants were mishandling the pesticides. Training on safe handling practices and incentives in form of personal-protective-equipments could be productive to ensure safety at work.

Abstract
Oxidative stress has been reported as one of the adverse effects caused due to pesticides, which is the main mechanism of the toxicity in humans and animals and is a useful parameter in monitoring studies. It involves an imbalance in the equilibrium state of ROS and antioxidant defenses leading to alterations in various antioxidant enzyme levels and lipid peroxidation. The objective of the current paper is to present a review of the potential role and protective mechanism action of the antioxidant micronutrient supplementation to ameliorate the oxidative stress induced by pesticides. Studies in animal models and human were retrieved through the relevant search of the literature and categorized. Various animal studies were categorized according to the type of supplementation. Animal studies provide evidence to conclude the potential protective role of antioxidants in ameliorating the adverse effects of pesticides. Similar studies in humans are meager suggesting for further comprehensive research.

Abstract
Background: Inevitable pesticide use in Indian agriculture has posed an increased risk of exposure to the farmers, which may lead to adverse health manifestations. Therefore, it is essential that the farmers must be aware of the harmful effects of pesticides. Aims and Objectives: To assess knowledge, practice and identify self-reported morbidity symptoms associated with pesticide use among farm women in the identified villages of Telangana, India. Materials and Methods: Community based cross-sectional study was conducted using a pre-tested questionnaire to carry out the survey among farmwomen. Results: 129 women working in agricultural farms were included in the study. Meagre knowledge regarding route of pesticide exposure was observed. Majority of them were not aware of toxicity symbols and never read the precautions on the pesticide containers. Inaccessibility was the main reason for insubstantial use of personal protective equipments (PPEs). Unsafe storage and disposal practices of containers were observed. Weakness (57.3%), headache (52%) and itching of skin (51.1%) were the common morbidity symptoms. Significant association was found between morbidity symptoms and use of PPE and hygienic practices, indicating importance of such practices. Conclusion: Improving knowledge which influences their practices and encouraging PPE use might be useful to remediate these issues. Monitoring studies may further aid to obtain the outcome of the awareness programmes and subsequently improved intervention methods can also be implemented.
