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.
OBJECTIVESThis 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.
METHODSA 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.
RESULTSSociodemographic 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%).
CONCLUSIONLow 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
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.
METHODSThis 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.
RESULTSMajority 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.
CONCLUSIONFilipino 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).
OBJECTIVESThis 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.
METHODSThis 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.
RESULTSLocal 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.
CONCLUSIONCapacity 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.

The current study aimed to clarify the roles of apolipoprotein A5 (ApoA5) and milk fat globule-epidermal growth factor 8 (Mfge8) in regulating myocardial lipid deposition and the regulatory relationship between them. The serum levels of ApoA5 and Mfge8 in obese and healthy people were compared, and the obesity mouse model induced by the high-fat diet (HFD) was established. In addition, primary cardiomyocytes were purified and identified from the hearts of suckling mice. The 0.8 mmol/L sodium palmitate treatment was used to establish the lipid deposition cardiomyocyte model in vitro. ApoA5-overexpressing adenovirus was used to observe its effects on cardiac function and lipids. The expressions of the fatty acid uptake-related molecules and Mfge8 on transcription or translation levels were detected. Co-immunoprecipitation was used to verify the interaction between ApoA5 and Mfge8 proteins. Immunofluorescence was used to observe the co-localization of Mfge8 protein with ApoA5 or lysosome-associated membrane protein 2 (LAMP2). Recombinant rMfge8 was added to cardiomyocytes to investigate the regulatory mechanism of ApoA5 on Mfge8. The results showed that participants in the simple obesity group had a significant decrease in serum ApoA5 levels (P < 0.05) and a significant increase in Mfge8 levels (P < 0.05) in comparison with the healthy control group. The adenovirus treatment successfully overexpressed ApoA5 in HFD-fed obese mice and palmitic acid-induced lipid deposition cardiomyocytes, respectively. ApoA5 reduced the weight of HFD-fed obese mice (P < 0.05), shortened left ventricular isovolumic relaxation time (IVRT), increased left ventricular ejection fraction (LVEF), and significantly reduced plasma levels of triglycerides (TG) and cholesterol (CHOL) (P < 0.05). In myocardial tissue and cardiomyocytes, the overexpression of ApoA5 significantly reduced the deposition of TG (P < 0.05), transcription of fatty acid translocase (FAT/CD36) (P < 0.05), fatty acid-binding protein (FABP) (P < 0.05), and fatty acid transport protein (FATP) (P < 0.05), and protein expression of Mfge8 (P < 0.05), while the transcription levels of Mfge8 were not significantly altered (P > 0.05). In vitro, the Mfge8 protein was captured using ApoA5 as bait protein, indicating a direct interaction between them. Overexpression of ApoA5 led to an increase in co-localization of Mfge8 with ApoA5 or LAMP2 in cardiomyocytes under lipid deposition status. On this basis, exogenous added recombinant rMfge8 counteracted the improvement of lipid deposition in cardiomyocytes by ApoA5. The above results indicate that the overexpression of ApoA5 can reduce fatty acid uptake in myocardial cells under lipid deposition status by regulating the content and cellular localization of Mfge8 protein, thereby significantly reducing myocardial lipid deposition and improving cardiac diastolic and systolic function.

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.

This study aimed to investigate the correlation between changes in intestinal toxicity and compositional alterations of Euphorbiae Ebracteolatae Radix(commonly known as Langdu) before and after milk processing, and to explore the detoxification mechanism of milk processing. Mice were intragastrically administered the 95% ethanol extract of raw Euphorbiae Ebracteolatae Radix, milk-decocted(milk-processed), and water-decocted(water-processed) Euphorbiae Ebracteolatae Radix. Fecal morphology, fecal water content, and the release levels of inflammatory cytokines tumor necrosis factor-α(TNF-α) and interleukin-1β(IL-1β) in different intestinal segments were used as indicators to evaluate the effects of different processing methods on the cathartic effect and intestinal inflammatory toxicity of Euphorbiae Ebracteolatae Radix. LC-MS/MS was employed to analyze the small-molecule components in the raw product, the 95% ethanol extract of the milk-processed product, and the milky waste(precipitate) formed during milk processing, to assess the impact of milk processing on the chemical composition of Euphorbiae Ebracteolatae Radix. The results showed that compared with the blank group, both the raw and water-processed Euphorbiae Ebracteolatae Radix significantly increased the fecal morphology score, fecal water content, and the release levels of TNF-α and IL-1β in various intestinal segments(P<0.05). Compared with the raw group, all indicators in the milk-processed group significantly decreased(P<0.05), while no significant differences were observed in the water-processed group, indicating that milk, as an adjuvant in processing, plays a key role in reducing the intestinal toxicity of Euphorbiae Ebracteolatae Radix. Mass spectrometry results revealed that 29 components were identified in the raw product, including 28 terpenoids and 1 acetophenone. The content of these components decreased to varying extents after milk processing. A total of 28 components derived from Euphorbiae Ebracteolatae Radix were identified in the milky precipitate, of which 27 were terpenoids, suggesting that milk processing promotes the transfer of toxic components from Euphorbiae Ebracteolatae Radix into milk. To further investigate the effect of milk adjuvant processing on the toxic terpenoid components of Euphorbiae Ebracteolatae Radix, transmission electron microscopy(TEM) was used to observe the morphology of self-assembled casein micelles(the main protein in milk) in the milky precipitate. The micelles formed in casein-terpenoid solutions were characterized using particle size analysis, fluorescence spectroscopy, ultraviolet spectroscopy, and Fourier-transform infrared(FTIR) spectroscopy. TEM observations confirmed the presence of casein micelles in the milky precipitate. Characterization results showed that with increasing concentrations of toxic terpenoids, the average particle size of casein micelles increased, fluorescence intensity of the solution decreased, the maximum absorption wavelength in the UV spectrum shifted, and significant changes occurred in the infrared spectrum, indicating that interactions occurred between casein micelles and toxic terpenoid components. These findings indicate that the cathartic effect of Euphorbiae Ebracteolatae Radix becomes milder and its intestinal inflammatory toxicity is reduced after milk processing. The detoxification mechanism is that terpenoid components in Euphorbiae Ebracteolatae Radix reassemble with casein in milk to form micelles, promoting the transfer of some terpenoids into the milky precipitate.

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.

OBJECTIVES:
To investigate the effect of interleukin-17 (IL-17) gene polymorphism on the susceptibility to cow's milk protein allergy (CMPA) in infants and its association with gut microbiota.
METHODS:
A prospective study was conducted involving 100 infants diagnosed with CMPA at the Women and Children's Hospital of Ningbo University from January 2022 to October 2024. A total of 100 healthy infants undergoing routine check-ups at the same hospital during the same period was enrolled as the control group. Medical information was obtained through the electronic medical record system. IL-17A (rs2275913) and IL-17F (rs1889570) polymorphisms were detected using polymerase chain reaction-restriction fragment length polymorphism method. Serum IL-17 levels were measured using enzyme-linked immunosorbent assay, and high-throughput sequencing was employed to analyze the relative abundance of Lactobacillus and Bifidobacterium. Multivariate logistic regression analysis was used to explore the influencing factors of CMPA occurrence in infants.
RESULTS:
The proportions of infants with a family history of allergy and those with vitamin D deficiency or insufficiency were significantly higher in the CMPA group compared to those in the control group (P<0.05). The distribution of IL-17F (rs1889570) genotypes showed significant differences between the CMPA and control groups (P<0.05), with the frequency of the A allele being significantly higher in the CMPA group (P<0.05). Multivariate logistic regression analysis revealed that a family history of allergy, vitamin D deficiency or insufficiency, and carrying the IL-17F (rs1889570) AA genotype were independent influencing factors for CMPA in infants (P<0.05). Infants in the CMPA group with the IL-17F (rs1889570) AA genotype had significantly higher serum IL-17 levels compared to those with AG/GG genotypes (P<0.05), while the relative abundance of Lactobacillus and Bifidobacterium was significantly lower (P<0.05).
CONCLUSIONS
IL-17F (rs1889570) gene polymorphism influences susceptibility to CMPA in infants, potentially through mechanisms involving IL-17 expression and the relative abundance of gut probiotics.

10.Role and Mechanism of Hyaluronic Acid-modified Milk Exosomes in Reversing Pemetrexed Resistance in Lung Adenocarcinoma Cells.
Chinese Journal of Lung Cancer 2025;28(9):658-666
BACKGROUND:
Lung cancer currently ranks first globally in both incidence and mortality. Pemetrexed (PMX) serves as a first-line treatment for lung adenocarcinoma (LUAD), but the patients often develop drug resistance during therapy. Milk exosome (mEXO) have the advantages of low immunogenicity, high tissue affinity, and low cost, and mEXO itself has anti-tumor effects. Hyaluronan (HA) naturally bind to CD44, a receptor which is highly expressed in LUAD tissues. This study aims to construct hyaluronan-modified milk exosome (HA-mEXO) and preliminarily investigate their molecular mechanisms for reversing PMX resistance through cellular experiments.
METHODS:
Exosomes were extracted from milk using high-speed centrifugation, and HA-mEXO was constructed. PMX-resistant A549 and PC-9 cell lines were treated with mEXO and HA-mEXO, respectively. CCK-8 assays, colony formation assays, Transwell assays, and flow cytometry were performed to evaluate proliferation, colony formation, migration, invasion, and apoptosis phenotypes in the treated resistant cell lines. Finally, transcriptomic sequencing, analysis, and cellular functional recovery experiments were conducted to investigate the mechanism by which HA-mEXO reverses PMX resistance in LUAD cells.
RESULTS:
The expression of CD44 in A549 and PC-9 LUAD drug-resistant cell lines was significantly higher than that in parental cells, and the uptake rate of HA-mEXO by drug-resistant cell lines was significantly higher than that of mEXO. Compared to the mEXO group, HA-mEXO-treated A549 and PC-9 resistant cells exhibited significantly reduced half maximal inhibitory concentration (IC50) values for PMX, markedly diminished clonogenic, migratory, and invasive capabilities, and a significantly increased proportion of apoptotic cells. Western blot analysis revealed that, compared to parental cells, A549 and PC-9 drug-resistant cells exhibited downregulated ZNF516 expression and upregulated ABCC5 expression. Immunofluorescence analysis revealed that HA-mEXO treatment downregulated ABCC5 expression in A549 and PC-9 drug-resistant cells compared to the PBS group, whereas co-treatment with HA-mEXO and ZNF516 knockdown showed no significant change in ABCC5 expression.
CONCLUSIONS
HA-mEXO carrying ZNF516 suppress ABCC5 expression, thereby enhancing the sensitivity of A549 and PC-9 LAUD drug-resistant cells to PMX.
