Asthma is one of the most common chronic inflammatory lung diseases among pregnant women. Acute asthma exacerbations during pregnancy negatively impact pregnancy outcomes. As myeloid-derived suppressor cell (MDSC) populations are known regulators of airway inflammation and are important in maternal-fetal tolerance, we investigated if percentages of circulating MDSC subsets correlated with clinical indicators of airway inflammation and maternal-fetal tolerance in a cohort of healthy pregnant (HP), asthmatic pregnant (AP) and well controlled asthmatic pregnant (WCAP) women recruited to the B-WELL Mom study.

According to a study conducted among a relatively healthy population of Mongolia (2017), the prevalence of hepatitis C virus (HCV) infection is 8.5%, which is considered a high prevalence of this infection. In addition to inflammation of the liver, other organ systems are affected by HCV infection, according to research.

Timely and efficient diagnosis of hepatitis C virus (HCV) infection remains the effective approach for the subsequent care cascade of HCV treatment. It is of importance in under-resourced areas. The study aimed to assess the feasibility of a point-of-care (POC) model by a rapid diagnostic test and subsequent confirmational HCV RNA test in remote islands where traffic is an additional hurdle for health care.

Research Question: Is growth or blood pressure altered among children conceived by fertility treatment compared with children conceived without use of treatment?

Design: The Upstate KIDS birth cohort originally oversampled for infants conceived by fertility treatment, including by IVF and intracytoplasmic sperm injection, by ovulation induction intrauterine insemination (IUI), or both. A total of 1658 families completed annual questionnaires for children aged 6-10 years, including children's weight, height and blood pressure as reported from paediatric visits. Age- and sex-specific z-scores of weight, height and body mass index (BMI) were calculated.

Background: Earlier feeding practices may influence dietary preference. We evaluated if age of introduction to select complementary foods shape intake and diet quality as measured by the Youth Healthy Eating Index (YHEI) in childhood.

Methods: Parents from the Upstate KIDS cohort reported complementary food introduction of 4-12-month-old infants on food questionnaires.

Background: Although diet quality during pregnancy and postpartum is important for multiple parent and child outcomes, within-person changes in diet quality throughout these periods have not been extensively examined.

Objectives: This study investigated diet quality from early pregnancy through 1 y postpartum and examined differences by sociodemographic characteristics in participants receiving obstetric care in Chapel Hill, North Carolina, United States.

Methods: Participants completed 24-h dietary recalls at 6 study visits (each pregnancy trimester and 6 wk, 6 mo, and 1 y postpartum) (n = 383).

Background/aims: Steatotic liver disease (SLD) is a common manifestation in chronic hepatitis C (CHC). Metabolic alterations in CHC are associated with metabolic dysfunction-associated steatotic liver disease (MASLD). We aimed to elucidate whether hepatitis C virus (HCV) eradication mitigates MASLD occurrence or resolution.

Background: Lower neighborhood opportunity, measured by the Child Opportunity Index [COI], is associated with increased pediatric morbidity, but is less frequently used to examine longitudinal well child care. We aimed to evaluate associations between the COI and well child visit [WCV] attendance from birth - <36 months of age.

Methods: The Upstate KIDS population-based birth cohort includes children born 2008-2010 in New York state.

We prospectively examined associations between mobility in neighborhood opportunity and early childhood recurrent wheezing/asthma. Downward mobility was associated with developing asthma, but not recurrent wheezing, though associations were attenuated after adjusting for family-level socioeconomic status. Elucidating how neighborhoods impact asthma may inform asthma equity initiatives in early childhood.

The purpose of this study was to assess the impact of telemedicine on ophthalmic screening and blood glucose control for patients with diabetes in remote areas of Northern Taiwan during the coronavirus disease 2019 (COVID-19) pandemic. Telemedicine was implemented in Shiding and Wanli Districts using a 5G platform from April 2021 to December 2022. Patients with poorly controlled diabetes received real-time consultations from endocrinologists at Far Eastern Memorial Hospital, 50 km away, for medication adjustment, diet control, and lifestyle recommendations.

Early infant growth trajectories have been linked to obesity risk. The aim of this study was to examine early infant feeding practices in association with anthropometric measures and risk of overweight/obesity in childhood. A total of 2492 children from Upstate KIDS, a population-based longitudinal cohort, were included for the analysis.

The stereoselectivity of glycosidic bond formation continues to pose a noteworthy hurdle in synthesizing carbohydrates, primarily due to the simultaneous occurrence of S1 and S2 processes during the glycosylation reaction. Here, we applied an in-depth analysis of the glycosylation mechanism by using low-temperature nuclear magnetic resonance and statistical approaches. A pathway driven by counterion exchanges and reaction byproducts was first discovered to outline the stereocontributions of intermediates.

The controlled attenuation parameter (CAP) measurement obtained from FibroScan is a low-risk method of assessing fatty liver. This study investigated the association between the FibroScan CAP values and nine anthropometric indicators, including the abdominal volume index (AVI), body fat percentage (BFP), body mass index (BMI), conicity index (CI), ponderal index (PI), relative fat mass (RFM), waist circumference (WC), waist-hip ratio (WHR), and waist-to-height ratio (WHtR), and risk of non-alcoholic fatty liver disease (fatty liver). We analyzed the medical records of adult patients who had FibroScan CAP results.

This study developed an eco-friendly method to synthesize 3-arylisoquinoline from 2-alkynylbenzaldehydes using Nafion® NR50 as an acidic catalyst and hexamethyldisilazane (HMDS) as a nitrogen source. The reaction proceeded a 6- cyclization under microwave irradiation, giving the corresponding isoquinolines in excellent yields. The advantages of this protocol include: (1) the use of recyclable acid catalysts, (2) transition-metal-free catalysis, and (3) the effective formation of the target product.

Purpose: To evaluate whether underlying infertility and mode of conception are associated with childhood behavioral disorders.

Methods: Oversampling on fertility treatment exposure using vital records, the Upstate KIDS Study followed 2057 children (of 1754 mothers) from birth to 11 years. Type of fertility treatment and time to pregnancy (TTP) were self-reported.

Article Synopsis
  • * Results indicated that HBsAg positivity was under 1% for those born after 1991, while HBV carriers showed elevated liver enzyme levels (ALT, AST) and lower body mass index (BMI) compared to non-carriers.
  • * A decline in anti-HBs positivity was noted, with plasma-derived vaccines showing better outcomes than recombinant vaccines; HBsAg presence was linked to higher likelihood of abnormal ALT levels.

Article Synopsis
  • The study analyzes the impact of achieving sustained virologic response (SVR) in patients with early-stage HCV-related hepatocellular carcinoma (HCC) in Taiwan, focusing on their clinical presentation and surgical outcomes.
  • Patients with post-SVR HCC demonstrated better liver function and a lower incidence of cirrhosis compared to those who either remained viremic or achieved SVR after resection.
  • The findings suggest that while patients with post-SVR HCC have improved liver health, their surgical outcomes are comparable to those who achieved SVR after resection, emphasizing the need for ongoing surveillance after SVR.

The pharmacological pathway of para-toluenesulfonamide (PTS) restricts the kinase activity of the mammalian target of rapamycin, potentially leading to reductions in cell division, cell growth, cell proliferation, and inflammation. These pathways have a critical effect on tumorigenesis. We aimed to examine the antitumor effect of PTS or PTS combined with cisplatin on canine melanoma implanted in BALB/c nude mice by estimating tumor growth, apoptosis expression, inflammation, and metastasis.
