Introduction: Poor feeding practices can result in malnutrition, which may have long-term negative effects on children’s physical and cognitive development. There is limited qualitative research exploring feeding practices among caregivers of urban poor, even though their children are highly vulnerable to undernutrition. Aim: This qualitative study aimed to explore and compare the feeding practices, barriers and coping strategies of caregivers of well-nourished and undernourished children aged three to five years living in public low-cost housing in Kuala Lumpur, Malaysia. Methods: Semi-structured in-depth interviews were conducted among 27 caregivers. Caregivers were purposively selected using purposive sampling and categorized into two groups based on their children’s growth status: families with well-nourished children (FWWC; n=15) and families with undernourished children (FWUC; n=12). Thematic analysis was conducted. Results: Two main themes emerged: feeding practices and barriers and coping strategies to feed children. FWWC caregivers demonstrated certain unique yet beneficial practices. They emphasized responsive feeding techniques, such as using nutritious snacks, promising outdoor activities, and involving children in meal preparation at home as effective strategies to increase children’s food intake. Contrarily, FWUC caregivers practiced less responsive feeding techniques, such as forcing, ignorance, and distraction. Caregivers from both groups experienced similar barriers (child barriers and family barriers) and applied comparable coping strategies (ignorance, distraction, pressure and force, compromise, and creativity). Conclusion: Understanding feeding practices of caregivers of healthy and undernourished children can guide the development of culturally tailored interventions and policies. These efforts can help address barriers and improve child nutrition through responsive feeding, ultimately preventing undernutrition.

Introduction: The growing population of international students in Malaysia has underscored the need to better understand their food preferences. Despite this, local studies addressing this topic have remained scarce. This study aimed to determine relationships between nutrition knowledge and food environment and their respective contributions to food preferences among international students at a Malaysian public university. Methods: This cross-sectional study included 619 international students. A structured questionnaire was used to assess general nutrition knowledge and food environment. Students were asked to rate their preferences for 77 food items using a five-point Likert scale, ranging from “dislike a lot” (1) to “like a lot” (5). The food items were categorised into six groups, namely animal foods (14 items), starches (12 items), dairy products (8 items), fruits (15 items), vegetables (20 items), and snacks (8 items). Results: A significant negative relationship was observed between dairy preference and affordability (r=-0.115, p=0.005). Students who lived off campus reported significantly greater preference for vegetables (M=75.49) than those who lived on campus (M=72.84). Nutrition knowledge related to diet, disease, and weight management emerged as the strongest predictor of fruit preference (β=0.257, p<0.001). Conclusion: General nutrition knowledge and food accessibility emerged as significant predictors of food preferences. Nutrition intervention programmes and efforts to improve access to fresh food options on campus may help encourage healthier food preferences among international students.

Introduction: Beckwith–Wiedemann syndrome (BWS) is a congenital overgrowth disorder associated with dysregulation of genes on chromosome 11p15.5. Infants with BWS can present with hyperinsulinemic hypoglycemia. There are also distinctive clinical features including macrosomia, macroglossia and visceromegaly that may raise suspicion of this diagnosis. Case: A preterm female infant of 30 weeks gestation with a birth weight of 1.87 kg (97th centile) had recurrent hypoglycemia in the neonatal period, requiring escalation to a maximum glucose infusion rate of 17.6 mg/kg/min. Hypoglycemia only resolved after starting intravenous glucagon infusion. Critical sampling during hypoglycemia revealed serum insulin 3.9 µU/mL (3–25 µU/mL), serum ketone 0.2 mmol/L, cortisol 3,053 nmol/L and growth hormone 16.2 ng/mL. These findings supported the diagnosis of non-ketotic hyperinsulinemic hypoglycemia. She was commenced on oral diazoxide with resolution of hypoglycemia and discontinuation of glucagon. Examination at birth revealed macroglossia, hepatomegaly and ballotable kidneys. An initial US abdomen at birth revealed bilateral enlarged kidneys but normal liver. An initial chromosomal study revealed karyotype 46, XX. Over time, additional clinical features became evident fulfilling the diagnostic criteria for BWS, that is, polyhydramnios, large for gestational age, transient hypoglycemia, hyperinsulinism, macroglossia, hemihypertrophy, facial nevi, bilateral ear creases, hepatomegaly and ballotable kidney. A repeat US abdomen surveillance at 4 months old revealed a heterogeneous liver mass with marked vascularity, prompting a diagnosis of hepatic hemangioma. She was commenced on oral propranolol, with reduction in the size and vascularity of the liver hemangioma and decline in alpha-fetoprotein levels. Conclusion The clinical features of BWS may not be recognizable in a preterm baby in early neonatal period. Careful clinical examination should be done in a baby with persistent hyperinsulinemic hypoglycemia for underlying syndromal causes. US surveillance should also be carried out due to increased risk of hepatoblastoma or liver hemangioma in BWS, as was seen in this case.

Introduction: Hypernatremia in preterm babies is often due to insensible water loss, inadequate fluid intake or sodium imbalance due to immature kidneys. Congenital nephrogenic diabetes insipidus (CNDI) is an uncommon cause of hypernatremia in neonates and presents shortly after birth. Early recognition is important to prevent severe dehydration, electrolytes imbalance and neurological complications. Case: We report a case of a preterm 32-week female infant, with a birth weight of 1.14 kg with persistent hypernatremia (146– 156 mmol/L) from day 4 of life. She received total parenteral nutrition since birth and was started on breastmilk since day 5 of life. The baby was mildly dehydrated with weight loss and high urea (6.5 mmol/L) at day 7 of life. Total fluids were increased to 160 mL/kg/day but serum sodium remained elevated even though the urea had normalized. The infant was also noted to have high urine output (5–6 mL/kg/hour) since day 3 of life and suboptimal weight gain. Further evaluation at age 1 month revealed urine osmolality 71 mOsm/kg, serum osmolality 308 mOsm/kg and urine sodium <20 mmol/L when serum sodium was 150 mmol/L, suggestive of DI. A trial of desmopressin showed unchanged serum sodium (Na), suggesting nephrogenic DI. Administration of intravenous fluids of 1/5NSD10% resulted in further increase of both sodium (159 mmol/L) and serum osmolality (326 mOsm/kg) with low urine osmolality (111 mOsm/kg). Intravenous fluids were discontinued and she was started on hydrochlorothiazide (1 mg/kg/dose bd), resulting in gradual normalization of sodium 138 mmol/L. Post discharge, she had good weight gain and normal developmental milestones at corrected age of 1.5-month-old. Due to early onset hypernatremia, the infant was referred for genetic testing to rule out CNDI. Conclusion Early onset persistent hypernatremia and high urine output despite adequate fluid management should prompt evaluation of DI. Early diagnosis is crucial to prevent a chronic state of hypernatremia that can lead to growth and developmental delay.

Objective: To investigate the health literacy level and its influencing factors among the elderly in Shunyi District, Beijing Municipality, so as to provide the evidence for developing health literacy intervention measures and improving the elderly's health literacy level. Methods: From September to November 2024, permanent residents aged ≥60 years in Shunyi District were selected by a multi-stage random sampling method combined with probability proportionate to size sampling method. The Chinese Elderly Health Literacy Questionnaire was used to conduct face-to-face surveys on basic information, health status, and health literacy. The health literacy level of the elderly was analyzed. Multivariable logistic regression model and decision tree model were used to analyze the influencing factors for health literacy level of the elderly. Results: There were 285 males (47.50%) and 315 females (52.50%). The mean age was (68.91±7.38) years. The health literacy level of the elderly was 14.33%. The literacy levels of basic concepts, basic knowledge, and basic skills were 43.33%, 5.33%, and 50.83%, respectively. The literacy levels of scientific aging concept, intrinsic capacity and geriatric syndromes, healthy lifestyle, information acquisition and self-care, health service utilization and chronic disease management, and safety and first aid were 52.33%, 7.17%, 51.83%, 58.83%, 72.00%, and 4.33%, respectively. Multivariable logistic regression analysis showed that educational level (high school/technical secondary school/technical school and above, OR=2.376, 95%CI: 1.020-5.532), monthly household income per capita (1 000-<3 500 yuan, OR=2.973, 95%CI: 1.349-6.555), residence (urban, OR=3.836, 95%CI: 2.071-7.105), and health attention (relatively concerned, OR=4.164, 95%CI: 1.779-9.742) were influencing factors for health literacy level of the elderly. Decision tree model results showed that educational level, monthly household income per capita, residence, and health attention were influencing factors for health literacy level of the elderly, with residence being the main influencing factor. Elderly people living in urban areas, relatively concerned about health, and with high school/technical secondary school/technical school and above educational level had higher health literacy level (40.00%). Conclusions The health literacy level of the elderly in Shunyi District is mainly affected by educational level, monthly household income per capita, residence, and health attention. It is recommended to focus on rural elderly with lower educational level, monthly household income per capita, and health attention.

Objective To investigate correlations of the ratio of specific brain region volume to total brain volume(ratio％),standard uptake value(SUV)of specific brain region based on 18F-FDG PET/MR examination in Alzheimer disease(AD)patients,as well as the relationship between changes of these two.Methods Fifty AD patients were retrospectively collected.Based on FDG PET/MR,the ratio％and the mean SUV(SUVmean)of 40 specific brain regions were obtained,and the correlation between ratio％and SUVmean for each region were evaluated.According to a database of normal brains,Z-scores for ratio％and SUVmean were calculated to represent structural and functional changes in AD patients,and the correlation between these 2 Z-scores was assessed.Results Correlations were found between ratio％and SUVmean,also between Z-scores of these two parameters in 29 brain regions(r=0.288 to 0.778,all P＜0.05).Among them 7 brain regions,i.e.bilateral middle temporal gyrus,right fusiform gyrus,right hippocampus,right precuneus,left lingual gyrus and right parahippocampal gyrus exhibited correlation coefficients greater than 0.6.Conclusion There were some relationships between brain structural and metabolic functions and their changes in AD patients showed on FDG PET/MR.

Objective:To compare the diagnostic efficacy of 18F-fibroblast activation protein inhibitor (FAPI) PET/MR and contrast-enhanced CT in detecting metachronous ovarian metastasis after gastric signet-ring cell carcinoma (GSRCC) surgery, and to evaluate its impact on clinical decision-making. Methods:This study employed a diagnostic test design. A retrospective analysis was conducted on 26 female patients with suspected metachronous ovarian metastasis following GSRCC resection between January 2023 and June 2025 in Renji Hospital, Shanghai Jiao Tong University School of Medicine. All patients underwent both 18F-FAPI PET/MR and contrast-enhanced CT within 2 weeks. Using histopathology or clinical imaging follow-up (≥6 months) as the reference standard, the diagnostic performance of both modalities was compared (McNemar test, Fisher exact test and Delong test), and changes in clinical management were analyzed. Results:Metachronous ovarian metastasis was confirmed in 12 patients (22 lesions). 18F-FAPI PET/MR showed significantly higher sensitivity (90.9%(20/22) vs 72.7%(16/22); χ2=4.10, P=0.043), specificity (100%(30/30) vs 50.0%(15/30); χ2=13.01, P<0.001), and accuracy (96.2%(50/52) vs 59.6%(31/52); χ2=15.43, P<0.001), compared to contrast-enhanced CT, with a significantly higher AUC (0.964 vs 0.815; Z=2.85, P=0.015). It also demonstrated superior detection of extraovarian metastases, including anastomotic recurrence, peritoneal spread, and lymph node involvement ( P values: 0.004-0.031), and identified 5 additional rare-site metastases in 3 patients that were missed by contrast-enhanced CT. Based on 18F-FAPI PET/MR findings, clinical management was adjusted in 6 patients with metastasis. Conclusion:18F-FAPI PET/MR outperforms contrast-enhanced CT in diagnosing metachronous ovarian metastasis and performing whole-body restaging in post-surgical GSRCC patients, therapy provides critical evidence for informing decision-making.

Objective To explore the effects and mechanism of Jianpi Shuyi Decoction in improving pancreatic fibrosis in chronic pancreatitis(CP)based on network pharmacology and animal experiments.Methods TCMSP was used to screen the active components and targets of Jianpi Shuyi Decoction.GeneCards was used to obtain the disease targets of pancreatic fibrosis,and the intersection of drug and disease targets was used to construct the protein interaction network and the drug-component-target network,and the core target genes were screened out.GO and KEGG pathway enrichment analysis was performed on the intersecting targets.Caerulein was used to induce CP mouse model,and Jianpi Shuyi Decoction was given for gavage.HE and Sirius red staining were used to observe pancreatic tissue inflammation and collagen deposition,respectively.RT-qPCR was used to observe the mRNA expression levels of Acta2,COL1A1,PI3K and Akt1 in pancreatic tissue.Immunohistochemistry staining was used to observe the protein expression levels of α-SMA,COL-1,p-PI3K and p-Akt in pancreatic tissues.Results A total of 181 active components were screened from Jianpi Shuyi Decoction,corresponding to 284 targets,with 240 targets overlapping between drugs and disease and the core targets were PTGS2,HSP90AA1,etc.193 signaling pathways were obtained from KEGG pathway enrichment analysis,primarily involving lipids and atherosclerosis,chemical carcinogenic-receptor activation,PI3K-Akt signaling pathway and others.The results of animal experiments showed that,compared with the normal group,the model group showed a large number of inflammatory cell infiltration and collagen deposition in pancreatic tissue,the mRNA expression of Acta2,COL1A1,PI3K and Akt1 in pancreatic tissue significantly increased(P<0.01),and the protein expression of α-SMA,COL-1,p-PI3K,p-Akt significantly increased(P<0.01);Jianpi Shuyi Decoction significantly reduced the inflammation and collagen deposition in pancreas of mice,reduced the mRNA expression of Acta2,COL1A1,PI3K and Akt1(P<0.05),and attenuated the protein expression of α-SMA,COL-1,p-PI3K and p-Akt in pancreatic tissue(P<0.05).Conclusion Jianpi Shuyi Decoction may exert a therapeutic effect on CP pancreatic fibrosis by regulating the PI3K/Akt signaling pathway,attenuating inflammation and collagen deposition in the pancreas,and reducing the levels of α-SMA and COL-1.

PURPOSE: The rate of complications among patients undergoing surgery has increased due to infection with SARS-CoV-2 and other variants of concern. However, Omicron has shown decreased pathogenicity, raising questions about the risk of postoperative complications among patients who are infected with this variant. This study aimed to investigate complications and related factors among patients with recent Omicron infection prior to undergoing orthopedic surgery. METHODS: A historical control study was conducted. Data were collected from all patients who underwent surgery during 2 distinct periods: (1) between Dec 12, 2022 and Jan 31, 2023 (COVID-19 positive group), (2) between Dec 12, 2021 and Jan 31, 2022 (COVID-19 negative control group). The patients were at least 18 years old. Patients who received conservative treatment after admission or had high-risk diseases or special circumstances (use of anticoagulants before surgery) were excluded from the study. The study outcomes were the total complication rate and related factors. Binary logistic regression analysis was used to identify related factors, and odds ratio (OR) and 95% confidence interval (CI) were calculated to assess the impact of COVID-19 infection on complications. RESULTS: In the analysis, a total of 847 patients who underwent surgery were included, with 275 of these patients testing positive for COVID-19 and 572 testing negative. The COVID-19-positive group had a significantly higher rate of total complications (11.27%) than the control group (4.90%, p < 0.001). After adjusting for relevant factors, the OR was 3.08 (95% CI: 1.45-6.53). Patients who were diagnosed with COVID-19 at 3-4 weeks (OR = 0.20 (95% CI: 0.06-0.59), p = 0.005), 5-6 weeks (OR = 0.16 (95% CI: 0.04-0.59), p = 0.010), or ≥7 weeks (OR = 0.26 (95% CI: 0.06-1.02), p = 0.069) prior to surgery had a lower risk of complications than those who were diagnosed at 0-2 weeks prior to surgery. Seven factors (age, indications for surgery, time of operation, time of COVID-19 diagnosis prior to surgery, C-reactive protein levels, alanine transaminase levels, and aspartate aminotransferase levels) were found to be associated with complications; thus, these factors were used to create a nomogram. CONCLUSION Omicron continues to be a significant factor in the incidence of postoperative complications among patients undergoing orthopedic surgery. By identifying the factors associated with these complications, we can determine the optimal surgical timing, provide more accurate prognostic information, and offer appropriate consultation for orthopedic surgery patients who have been infected with Omicron.
