Background/Aims: Pediatric patients with suspected gastroparesis often undergo antroduodenal manometry (ADM) and gastric emptying scintigraphy (GES) for diagnostic purposes. However, it is unknown if delayed gastric emptying (DGE) correlates with manometric findings. This study evaluates whether ADM parameters differ between normal and abnormal GES in pediatric patients. Methods: Data from pediatric patients undergoing ADM and GES at Nationwide Children’s Hospital from 2011-2020 were retrospectively reviewed. Manometry parameters including motility index (Ln [sum of amplitudes × number of contractions + 1]), number of antral contractions, and direction of the phase III migrating motor complex (MMC) were compared to GES results from age-matched patients with DGE (n = 32) and normal gastric emptying (NGE) (n = 32) of similar sex, body mass index, and weight. Results: Children with DGE had a lower post-prandial antral motility index and antral contraction number than those with NGE (9.4 vs 11.2, P = 0.005; 21.8 vs 49.6, P < 0.001). The gastric emptying percentage at 4 hours was lower in patients with retrograde phase III (59.2% vs 83.9%,P = 0.022) and in those without an antral component in the fasting phase III of the migrating motor complex (70.3% vs 86.5%, P = 0.003). Post-prandial antral hypomotility occurred more frequently in the DGE group than in the NGE group (41% vs 9%, P = 0.008). Conclusions ADM findings differ between children with DGE and NGE. Children with DGE are more likely to have abnormal fasting phase III patterns and decreased post-prandial antral activity during ADM testing.

BACKGROUND

Intraoperative transfusion for gynecologic surgery, when appropriately used, can improve patient outcomes. However, when utilized incorrectly, blood transfusion can worsen patient outcomes and increase patient cost. This study aimed to evaluate the blood transfusion practices of tertiary hospitals in the Philippines.

The study utilized a cross-sectional design wherein prospective data were gathered through multiple sources across seven tertiary-level hospitals. Women admitted to undergo gynecologic surgery were recruited based on a set of criteria. A chart review was conducted, and blood utilization indices were calculated. Outcomes were compared between public versus private facilities and transfused versus nontransfused patients.

Among 514 patients, 79.7% underwent cross-matching and 75.1% received transfusions. Adverse events were rare, with no transfusion-related deaths. The overall crossmatch-to-transfusion ratio (C/T ratio) was 2.8, exceeding the 2.5 optimal benchmark; all public hospitals recorded a C/T ratio >2.5, whereas private centers had more efficient usage. Six hospitals met acceptable benchmarks for transfusion probability and transfusion index. Open abdominal procedures, particularly hysterectomy, accounted for the most blood used. Transfused patients had longer operative times, greater blood loss, lower preoperative hemoglobin, and more frequently involved resident physicians in training. Public hospitals recorded higher cross-match and transfusion rates, greater resident physician participation, and broader use of general anesthesia.

Results of the study highlight the importance of monitoring blood transfusion parameters to optimize blood utilization. The observed differences between public and private institutions in the country highlight the urgent need for standardized and evidence-based practice to ensure efficient transfusion protocols nationwide.

Background::Previous studies have reported associations of specific maternal and paternal lifestyle factors with offspring’s cognitive development during early childhood. This study aimed to investigate the prospective associations between overall parental lifestyle and offspring’s cognitive performance during adolescence and young adulthood in China.Methods::We included 2531 adolescents aged 10-15 years at baseline in 2010 from the China Family Panel Studies. A healthy parental lifestyle score (ranged 0-5) was constructed based on the following five modifiable lifestyle factors: Smoking, drinking, exercise, sleep, and diet. Generalized estimating equation models were used to examine the association between baseline parental healthy lifestyle scores and offspring’s fluid and crystallized intelligence in subsequent years (2012, 2014, 2016, and 2018).Results::Offspring in the top tertile of parental healthy lifestyle scores performed better in overall fluid intelligence (multivariable-adjusted β = 0.53, 95% confidence interval [CI]: 0.29-0.77) and overall crystallized intelligence (multivariable-adjusted β = 0.35, 95% CI: 0.16-0.54) than those in the bottom tertile of parental healthy lifestyle scores. The results were similar after further adjustment for the offspring’s healthy lifestyle scores and persisted across the subgroups of parental socioeconomic status. Additionally, maternal and paternal healthy lifestyle scores were independently associated with better offspring’s cognitive performance, with significant contribution observed for paternal never-smoking, weekly exercise, and diversified diet. When both parents and offspring adhered to a healthier lifestyle, we observed the highest level of the offspring’s overall crystallized intelligence. Conclusions::Our study indicates that parental adherence to a healthier lifestyle is associated with significantly better offspring’s cognitive performance during adolescence and early adulthood, regardless of socioeconomic status. These findings highlight the potential cognitive benefits of promoting healthy lifestyles among parents of adolescents.

Abstract： Objective　To understand the new HIV-1 infection in MSM (men who have sex with men) sentinel population in Haikou and explore the influencing factors of HIV/AIDS epidemic, so as to provide a basis for AIDS prevention and control. Methods　A continuous cross-sectional study was used to detect HIV-1 infection in the MSM sentinel surveillance population in Haikou City from 2019 to 2023, excluding those with known past positive results and those who had been on antiretroviral therapy for more than six months. The positive cases suitable for new infection testing were examined by HIV-1 restriction antigen affinity enzyme immunization method, and binary non-conditional logistic regression model conducted multivariate analysis of new infections. Results　A total of 2 001 MSM were recruited, with a median age M（P25, P75）of 28 (23, 33) years, 89.8% were recruited from the Internet, 90.8% were single; 79.7% resided in the local area for >2 years, 72.6% were educated to college level or above, and the proportion of household registration in the province was 78.0%. From 2019 to 2023, the HIV-1 positive rate among MSM in Haikou from 2019 to 2023 was 6.85% (137/2 001), with a new infection rate of 2.95% (59/2 001). The estimated new infection rate was 8.61% (95%CI: 6.41-10.81), with no significant trend changes in HIV-1 positivity and new infection rates over the years (P>0.05). Multivariate analysis revealed that, compared to those who lived locally for ≤2 years, those residing locally for >2 years had a lower probability of recent HIV-1 infection (OR=0.473，95%CI: 0.273-0.821). Compared to those who had never received intervention services, those who had received such services had a lower risk of recent HIV-1 infection (OR=0.347, 95%CI:0.197-0.613). Conclusions　In recent years, the Haikou MSM population has shown characteristics of higher education and younger age, and the rate of new HIV-1 infections has not changed significantly. Receiving intervention services is the protection factor to prevent HIV-1 new infections, whereas the mobile MSM population has a higher risk of HIV-1 new infection. Health management of the mobile MSM population should be strengthened to expand the coverage of AIDS intervention services.

Objective To observe the expression of adhesion molecule CD226 on the small intestinal group 3 innate lymphoid cells (ILC3) in mice. Methods The bioinformatics was used to analyze the expression of CD226 on murine ILCs. Small intestinal mucosal lamina propria lymphocytes (LPL) were isolated from wild-type C57BL/6J mice, and the expression of CD226 on ILC1 and ILC3 was detected by flow cytometry. A mouse model of dextran sulfate sodium (DSS)-induced colitis was constructed to observe the changes in the expression of CD226 on ILC3. Results Both ILC1 and ILC3 in the mice small intestine expressed CD226 molecules; the proportion of ILC3 was reduced, while the expression level of CD226 on ILC3 was increased in the colitis model. Conclusion CD226 is expressed on the small intestines of mice, and although the proportion of ILC3 decreases in the DSS-induced colitis, the expression of CD226 on ILC3 increases.

Objective To explore the phenotypic conversion of regulatory T cells (Tregs) in the lungs of mice with bronchopulmonary dysplasia (BPD)-affected mice. Methods A total of 20 newborn C57BL/6 mice were divided into air group and hyperoxia group, with 10 mice in each group. The BPD model was established by exposing the newborn mice to hyperoxia. Lung tissues from five mice in each group were collected on postnatal days 7 and 14, respectively. Histopathological changes of the lung tissues was detected by HE staining. The expression level of surfactant protein C (SP-C) in the lung tissues was examined by Western blot analysis. Flow cytometry was performed to assess the proportion of FOXP3⁺ Tregs and RORγt⁺FOXP3⁺ Tregs in CD4⁺ lymphocytes. The concentrations of interleukin-17A (IL-17A) and IL-6 in lung homogenate were measured by using ELISA. Spearman correlation analysis was used to analyze the correlation between FOXP3⁺Treg and the expression of SP-C and the correlation between RORγt⁺FOXP3⁺ Tregs and the content of IL-17A and IL-6. Results The hyperoxia group exhibited significantly decreased levels of SP-C and radical alveolar counts in comparison to the control group. The proportion of FOXP3⁺Tregs was reduced and that of RORγt⁺FOXP3⁺Tregs was increased. IL-17A and IL-6 concentrations were significantly increased. SP-C was positively correlated with the expression level of RORγt⁺FOXP3⁺ Tregs. RORγt⁺FOXP3⁺ Tregs and IL-17A and IL-6 concentrations were also positively correlated. Conclusion The number of FOXP3⁺ Tregs in lung tissue of BPD mice is decreased and converted to RORγt⁺ FOXP3⁺ Tregs, which may be involved in hyperoxy-induced lung injury.
