Objective: To investigate how sociodemographic and medical care access variables are associated with influenza vaccine uptake among pregnant women in the USA.

Methods: This is an observational study using 2015-2019 data from the US Behavioral Risk Factor Surveillance System. Pregnant women aged 18-49 years were included.

Implementing Locally Tailored Strategies to Promote Redemption of Farmers' Market Nutrition Program Vouchers Among WIC Participants in Central Pennsylvania.

The Pennsylvania Farmers' Market Nutrition Program (FMNP) provides vouchers to participants of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) to purchase locally grown fruits, vegetables (F&V), and herbs every year from June to November. Voucher redemption is suboptimal among WIC participants in Lebanon County, a community with high numbers of low-income and Hispanic families. Supported by a Racial and Ethnic Approaches to Community Health (REACH) award, our community-academic coalition partnered with the local WIC provider to implement locally tailored strategies to promote redemption of FMNP vouchers.

Role of the adaptive immune system in diabetic kidney disease.

Diabetic kidney disease (DKD) is a highly prevalent complication of diabetes and the leading cause of end-stage kidney disease. Inflammation is recognized as an important driver of progression of DKD. Activation of the immune response promotes a pro-inflammatory milieu and subsequently renal fibrosis, and a progressive loss of renal function.

Exercise does not improve insulin resistance and mitochondrial characteristics together.

The aim of this study was to investigate the relationship between mitochondrial content and respiratory function and whole-body insulin resistance in high-fat diet (HFD) fed rats. Male Wistar rats were given either a chow diet or an HFD for 12 weeks. After 4 weeks of the dietary intervention, half of the rats in each group began 8 weeks of interval training.

Enhancing community engagement in Patient-Centered Outcomes Research: Equipping learners to thrive in translational efforts.

Community engagement is a critical component of translational research. Innovative educational approaches to support meaningful involvement of stakeholders in clinical research allows for bidirectional learning and greater engagement in translational efforts. Our Penn State Community-Engaged Research Core (CeRC) team has developed an innovative research curriculum for a variety of stakeholders, including patient partners, organizational representatives, and Community Health Workers (CHWs).

Ammonium chloride administration prior to exercise has muscle-specific effects on mitochondrial and myofibrillar protein synthesis in rats.

Aim: Exercise is able to increase both muscle protein synthesis and mitochondrial biogenesis. However, acidosis, which can occur in pathological states as well as during high-intensity exercise, can decrease mitochondrial function, whilst its impact on muscle protein synthesis is disputed. Thus, the aim of this study was to determine the effect of a mild physiological decrease in pH, by administration of ammonium chloride, on myofibrillar and mitochondrial protein synthesis, as well as associated molecular signaling events.

Maternal exercise attenuates the lower skeletal muscle glucose uptake and insulin secretion caused by paternal obesity in female adult rat offspring.

Key Points: Paternal obesity negatively influences metabolic outcomes in adult rat offspring. Maternal voluntary physical activity has previously been reported to improve glucose metabolism in adult rat offspring sired by healthy fathers. Here, we investigated whether a structured programme of maternal exercise training before and during gestation can attenuate the negative impacts that paternal obesity has on insulin sensitivity and secretion in female adult offspring.

Four weeks of exercise early in life reprograms adult skeletal muscle insulin resistance caused by a paternal high-fat diet.

Key Points: A paternal high-fat diet/obesity before mating can negatively influence the metabolism of offspring. Exercise only early in life has a remarkable effect with respect to reprogramming adult rat offspring exposed to detrimental insults before conception. Exercise only early in life normalized adult whole body and muscle insulin resistance as a result of having a high-fat fed/obese father.

The androgen receptor in bone marrow progenitor cells negatively regulates fat mass.

It is well established that testosterone negatively regulates fat mass in humans and mice; however, the mechanism by which testosterone exerts these effects is poorly understood. We and others have shown that deletion of the androgen receptor (AR) in male mice results in a phenotype that mimics the three key clinical aspects of hypogonadism in human males; increased fat mass and decreased bone and muscle mass. We now show that replacement of the gene specifically in mesenchymal progenitor cells (PCs) residing in the bone marrow of Global-ARKO mice, in the absence of the AR in all other tissues (PC-AR Gene Replacements), completely attenuates their increased fat accumulation.

The role of oxidative stress in renal injury induced in rats by losartan exposure during lactation.

Introduction: Rats exposed to angiotensin II (AII) receptor antagonists during lactation present progressive disturbances in renal development that lead to progressive alterations in renal function and structure. This study evaluates the role of oxidative stress in the renal changes induced by exposure to losartan, a type 1 AII receptor antagonist, in rats during lactation.

Materials And Methods: Male Wistar pups were divided into: Control, pups of dams that received 2% sucrose solution; Control-tempol, pups of dams that received tempol (0.

Renal Development and Blood Pressure in Offspring from Dams Submitted to High-Sodium Intake during Pregnancy and Lactation.

Exposure to an adverse environment in utero appears to programme physiology and metabolism permanently, with long-term consequences for health of the fetus or offspring. It was observed that the offspring from dams submitted to high-sodium intake during pregnancy present disturbances in renal development and in blood pressure. These alterations were associated with lower plasma levels of angiotensin II (AII) and changes in renal AII receptor I (AT(1)) and mitogen-activated protein kinase (MAPK) expressions during post natal kidney development.

Postnatal renal abnormalities in rats exposed to losartan during lactation.

Background/aims: Rats exposed to losartan during lactation exhibit progressive changes in renal function and structure. This study analyzed the early events in pups from dams that received losartan during lactation.

Methods: Male Wistar rats from dams that received 2% sucrose (control, n = 25) or losartan (100 mg/kg/day) diluted in 2% sucrose (n = 33) during lactation were anesthetized 21 days after birth.

Role of endogenous hydrogen sulfide on renal damage induced by adriamycin injection.

A single injection of adriamycin (ADR) induces marked and persistent proteinuria in rats that progress to glomerular and tubulointerstitial lesions. It has been shown that ADR-induced nephrotoxicity is mediated, at least in part, by oxidative stress that lead to inflammation. Endogenous hydrogen sulfide (H₂S) is synthesized from L-cysteine and is an important signaling molecule in inflammation.

Renal structure and function evaluation of rats from dams that received increased sodium intake during pregnancy and lactation submitted or not to 5/6 nephrectomy.

Adult rats submitted to perinatal salt overload presented renin-angiotensin system (RAS) functional disturbances. The RAS contributes to the renal development and renal damage in a 5/6 nephrectomy model. The aim of the present study was to analyze the renal structure and function of offspring from dams that received a high-salt intake during pregnancy and lactation.

MAPK and angiotensin II receptor in kidney of newborn rats from losartan-treated dams.

Several lines of evidence suggest that angiotensin II (A-II) participates in the postnatal development of the kidney in rats. Many effects of A-II are mediated by mitogen-activated protein kinase (MAPK) pathways. This study investigated the influence that treatment with losartan during lactation has on MAPKs and on A-II receptor types 1 (AT(1)) and 2 (AT(2)) expression in the renal cortices of the offspring of dams exposed to losartan during lactation.
