BACKGROUND

In the Philippines, the prevalence of food insecurity increased during the COVID-19 pandemic, affecting the nutritional status of communities nationwide. Urban areas in particular are vulnerable to the harmful effects of food insecurity, and the effects are extended and magnified when it comes to children.

This study aims to evaluate the coping strategies of households with children aged 0-10 years old in an urban poor community in Quezon City. In particular, the study will determine Coping Strategies Index (CSI) scores and the frequency of specific coping strategies used.

A descriptive cross-sectional study was conducted to assess the coping strategies of 405 households with children in the community during the pandemic. Mothers or caregivers were given a survey inquiring about the sociodemographic data and CSI.

Sociodemographic profiling showed that the households generally belonged to class D and E (PhP 15,000 and below) income households (73.8%). The majority of the household heads (52.6%) have their highest educational attainment at the high school level. The majority (77.5%) of the households were categorized as having low CSI classification (90%CI: 73.9, 80.8). This could indicate that relief operations conducted in the community may have helped ease their food insecurity. Coping strategies that were most frequently employed by the households were depending on less preferred or more affordable food (74.8%), rationing money for prepared food (69.1%), and purchasing food on credit (58.5%).

Low CSI classification was noted, which may be due to increased adaptation to persistent food insecurity and the utilization of coping strategies not indicated in the questionnaire. Common coping strategies used by households include reliance on less favored or less costly food items, rationing resources for prepared food, and food on credit. It is recommended that the results collected be used to target food availability and accessibility interventions in the community.

OBJECTIVES: To analyze the potential causal relationship between gut microbiota and food allergy (FA) using two-sample Mendelian randomization (MR) methods. METHODS: Data from genome-wide association studies on gut microbiota and FA were utilized. MR analysis was conducted employing inverse variance weighting, MR-Egger regression, and weighted median methods to assess the causal relationship between gut microbiota and FA. Cochrane's Q test was used to evaluate heterogeneity of instrumental variables, MR-PRESSO analysis was conducted to test for outliers and pleiotropy, and MR-Egger regression was employed to assess horizontal pleiotropy. The "leave-one-out" method was used to evaluate the impact of removing individual single nucleotide polymorphisms on the causal relationship. RESULTS: Inverse variance weighting analysis revealed that the phylum Verrucomicrobia, family Verrucomicrobiaceae, order Verrucomicrobiales, genus Ruminococcaceae UCG013, and genus Akkermansia were negatively associated with FA (P<0.05). Sensitivity analyses confirmed the reliability of the findings, indicating no heterogeneity or pleiotropy present. CONCLUSIONS There is a causal relationship between gut microbiota and FA, with Verrucomicrobia, Verrucomicrobiaceae, Verrucomicrobiales, Ruminococcaceae UCG013, and Akkermansia potentially reducing the risk of developing FA. These findings provide potential targets for the treatment and prevention of FA; however, further research is needed to explore the specific mechanisms by which the microbiota influence FA.

BACKGROUND: Since the accident at Fukushima Daiichi Nuclear Power Plant (FDNPP), concerns have arisen in Japan regarding the presence of radionuclides in food. Moreover, exposure levels to ⁹⁰Sr and Pu isotopes in adults and those to ¹³⁴Cs+¹³⁷Cs, ⁹⁰Sr, and Pu (where Cs, Sr, and Pu are cesium, strontium, and plutonium, respectively) in children have not been examined. Therefore, this study employed a duplicate portion approach to examine dietary exposure levels of radionuclides in adults and children following the FDNPP accident. METHODS: The study spanned fiscal years 2012-2014 and was conducted in 10 prefectures: Hokkaido, Iwate, Miyagi, Fukushima, Ibaraki, Saitama, Tokyo, Kanagawa, Osaka, and Kochi. The participants provided portions of their meals for two non-consecutive days and completed questionnaires on the meal items. The activity concentrations of ¹³⁴Cs, ¹³⁷Cs, ⁹⁰Sr, and ^239+240Pu, which are targets of standard limits for radionuclides in foods in Japan, were determined according to the Radioactivity Measurement Series. The daily intake was calculated based on the radionuclide activity concentrations in the duplicate portion samples, and the committed effective doses were estimated using dose coefficients for the ingestion of each radionuclide provided by the International Commission on Radiological Protection. RESULTS: Approximately 80 duplicate samples were obtained in each fiscal year, and 242 samples were collected. The highest summed activity concentration of ¹³⁴Cs and ¹³⁷Cs was 11 Bq/kg, which was recorded in Date City (child) in 2013; this level was approximately one-ninth of the standard limit for general foods (100 Bq/kg). The committed effective dose from annual ingestion of the sample described above was 74 µSv, approximately 14 times lower than the maximum permissible level of 1 mSv/y. Pu was not detected and the ⁹⁰Sr activity concentrations were similar to those before the FDNPP accident. CONCLUSIONS For the samples examined in the present study, the ¹³⁴Cs, ¹³⁷Cs, ⁹⁰Sr, and ^239+240Pu dietary exposure levels were considerably lower than the regulatory levels and may not pose a health risk.

Per- and polyfluoroalkyl substances (PFAS) have recently been shown to affect human health at low levels in the blood, according to epidemiological evidence. Consequently, human exposure to these chemicals should be strictly controlled to prevent health risks. This review reports on the potential sources of PFAS using Japan as an example. Tap water has attracted attention as a source of exposure to PFAS. PFAS have also been detected in the air, in household dust, and in consumer products. Furthermore, in the general population, diet is the most common source of exposure, and there is particular concern about human exposure to PFAS accumulated in seafood. Continuous monitoring is important for appropriate management of exposure for both humans and the environment.

OBJECTIVES

This study aims to describe the micronutrient intake and diet quality of overweight and obese Filipino adults in the National Capital Region (NCR). Specifically, it seeks to assess micronutrient inadequacy among these individuals and analyze differences in food intake based on their sociodemographic profiles and lifestyle habits.

This analytical cross-sectional study utilized data from the Expanded National Nutrition Survey (ENNS) conducted in 2018, 2019, and 2021 by the Department of Science and Technology-Food and Nutrition Research Institute (DOST-FNRI). A total of 3,154 overweight and obese subjects were included. ANOVA and Kruskal-Wallis tests were employed to analyze the food groups consumed by these adults.

Majority of overweight and obese adults were found to be inadequate in vitamin A (81.7%), vitamin C (88.4%), thiamin (62.5%), riboflavin (70.7%), iron (69.8%), and calcium (88.7%). Significant differences were observed in the mean intake of various food groups across different age groups, sexes, civil statuses, wealth quintiles, educational attainments, employment statuses, and smoking and drinking statuses.

Filipino adults who are overweight and obese, and residing in urban settings face significant challenges related to micronutrient inadequacy. When their food intake was assessed based on sociodemographic and lifestyle characteristics, it was found that their diets were more calorie-dense than nutrient-dense. To address this issue, it is recommended to encourage a wider variety of nutrient-dense foods among overweight and obese adults.

BACKGROUND

Filipino farmers recorded the highest incidence of poverty in the last decade. In addition, a heightened awareness was observed within agriculture and different government agencies to better understand the link between agriculture and nutrition. However, limited studies have been conducted in the Philippines integrating nutritionsensitive agriculture into the Municipal Agricultural Development Plan (MADP).

This study aims to determine the effect of capacity building on the knowledge, attitude, and self-efficacy of municipal agriculturists on Nutrition-Sensitive Agriculture (NSA) in CALABARZON.

This study utilized a non-randomized controlled trial design to measure the change in knowledge, attitude, and self-efficacy of the municipal agriculturists on NSA and nutrition sensitivity of the MADP. A total of 57 municipal agriculturists from CALABARZON participated in the capacity building.

Local agriculture planners' knowledge, attitude, and self-efficacy significantly improved after capacity building. In addition, membership of municipal agriculturists to local nutrition committee was significantly associated with higher scores difference in knowledge and self-efficacy after the training. Meanwhile, the score difference in their attitude was significantly related to the tenure of employment in local agriculture planners.

Capacity building on the NSA can significantly improve local agriculture planners' knowledge, attitude, and self-efficacy. Thus, the government must support programs and initiatives concerning the NSA, like increasing the capacity of local agriculture planners. This will allow them to integrate nutrition-sensitive agriculture concepts positively into their agriculture development plan.

Signal detection is a critical task in drug safety regulation. However, it inevitably generates irrelevant or false signals, posing challenges for resource allocation by marketing authorization holders. To reasonably assess these signals, different countries have established various principles for prioritizing the evaluation of risk signals. This study systematically compares these principles and finds that the U.S. Food and Drug Administration(FDA) focuses on practical issues, such as identifying drug confusion or drug interactions. However, China's Good Pharmacovigilance Practices and the European Medicines Agency(EMA) emphasize a comprehensive evaluation framework. The Council for International Organizations of Medical Sciences(CIOMS) emphasizes the consistency of multiple data sources, highlighting the reliability of signal evaluation. China practices a multidisciplinary approach combining traditional Chinese and western medicine, and the risk signals related to traditional Chinese medicine(TCM) have unique characteristics, including complex components, cumulative toxicity, specific theoretical foundations, and drug interactions. The different priorities in risk signal evaluation principles across countries suggest that China should strengthen clinical trial research, emphasize corroboration with evidence of multiple sources, and pay particular attention to the risks of drug interactions in the TCM regulatory science. Establishing the risk signal prioritization principles that align with the characteristics of TCM enables more precise and efficient scientific regulation of TCM.

Objective:To investigate the clinical characteristics and major allergens of patients with pollen-food allergy syndrome（PFAS） and their correlation with the severity of symptoms, and to provide a basis for identifying high-risk patients, optimizing the allergen testing process and developing individualized dietary management strategies. Methods:The clinical data of 166 patients with PFAS admitted to our hospital from January 2021 to July 2023 were retrospectively analyzed. The clinical symptoms, pollen types and food allergy of the patients were analyzed by questionnaire survey and serum specific IgE detection. phi coefficient, Apriori algorithm modeling and multivariate logistic regression analysis were used to evaluate the association between allergen and symptom severity. Results:Artemisia pollen was the most common allergen in this area, with a positive rate of 96.39%. Peach and mango were the most common food allergens, which caused allergic reactions in 24.10% and 22.89% of patients, respectively. Oral mucosal symptoms were the main symptoms. Correlation analysis showed that there was a correlation between pollen allergens and allergenic food. Association rule analysis showed that when the patient was allergic to the combination of peanuts and trees, the probability of high severity of symptoms was 82.35%. Multivariate analysis showed that ragweed allergy was significantly positively correlated with the severity of PFAS symptoms. Conclusion:Artemisia pollen and related food allergens play an important role in the pathogenesis of PFAS. Association rule mining and network map analysis revealed direct associations between peanut and tree combination allergy and symptom severity, as well as potential links between other inhaled allergens and specific food allergies. Ragweed and peach allergy are independent risk factors for the aggravation of PFAS symptoms, which can be used as early warning indicators. These results help to improve the screening of high-risk patients and the construction of regional allergen databases.
