The NCCN Guidelines for Survivorship include recommendations for screening, evaluation, and treatment of psychosocial and physical problems resulting from adult-onset cancer and its treatment. They also include recommendations to promote healthy behaviors and immunizations in survivors and provide a framework for care coordination. These NCCN Guidelines Insights summarize the panel's current recommendations regarding sexual health and fertility.

Prior work has identified a key role for glial cells, including microglia, in the multifaceted and temporally evolving neuroimmune response to both stroke and CSVD. Transcriptional profiling has led to important advances including identification of distinct gene expression signatures in ischemia-exposed, flow cytometrically sorted microglia and more recently single cell RNA sequencing-identified microglial subpopulations or clusters.

Here we present evidence from high-precision analyses of stable K isotopes in rats maintained on a control diet that the tissues and organs involved in the internal redistribution of K differ in their speed of K exchange with ECF and can be grouped into those that exchange K with ECF either rapidly or more slowly ("fast" and "slow" pools). After 10 days of K restriction, a compartmental analysis indicates that the sizes of the ICF K pools decreased but that this decrease in ICF K pools was not homogeneous, rather occurring only in the slow pool (15% decrease, < 0.

Assessing renal transporter abundance with antibody probes by immunoblotting is an essential tool for mechanistic studies. Although journals require authors to demonstrate antibody specificity, there are no consensus guidelines for kidney sample preparation leading to lab-to-lab variability in immunoblot results.

Uninephrectomy-associated proteinuria could be attributed to elevated single-nephron GFR and downregulation of megalin, which reduced fractional protein endocytosis.
Background: Losing or donating a kidney is associated with risks of developing hypertension and albuminuria.
Background: The vasoconstrictor effects of angiotensin II via type 1 angiotensin II receptors in vascular smooth muscle cells are well established, but the direct effects of angiotensin II on vascular endothelial cells (VECs) in vivo and the mechanisms how VECs may mitigate angiotensin II-mediated vasoconstriction are not fully understood. The present study aimed to explore the molecular mechanisms and pathophysiological relevance of the direct actions of angiotensin II on VECs in kidney and brain microvessels in vivo.
Methods And Results: Changes in VEC intracellular calcium ([Ca]) and nitric oxide (NO) production were visualized by intravital multiphoton microscopy of cadherin 5-Salsa6f mice or the endothelial uptake of NO-sensitive dye 4-amino-5-methylamino-2',7'-difluorofluorescein diacetate, respectively.
Social deficits are debilitating features of many psychiatric disorders, including autism. While time-intensive behavioral therapy is moderately effective, there are no pharmacological interventions for social deficits in autism. Many studies have attempted to treat social deficits using the neuropeptide oxytocin for its powerful neuromodulatory abilities and influence on social behaviors and cognition.

Chronic infusion of subpressor level of angiotensin II (ANG II) increases the abundance of Na transporters along the distal nephron, balanced by suppression of Na transporters along the proximal tubule and medullary thick ascending limb (defined as "proximal nephron"), which impacts K handling along the entire renal tubule. The objective of this study was to quantitatively assess the impact of chronic ANG II on the renal handling of Na and K in female rats, using a computational model of the female rat renal tubule. Our results indicate that the downregulation of proximal nephron Na reabsorption (T), which occurs in response to ANG II-triggered hypertension, involves changes in both transporter abundance and trafficking.

However, it is challenging to inhibit the suppressive function of T for cancer therapy without affecting immune homeostasis. Identifying pathways that may distinguish tumor-restricted T is important, yet the transcriptional programs that control intratumoral T gene expression, and that are distinct from T in healthy tissues, remain largely unknown.

The epithelial transport processes along the renal tubule that match output to input have long been the subject of experimental and theoretical study. However, emerging data have identified a new dimension of investigation: sex.

Background: Employers and pharmacies are challenged by a complex system for prescription payment. Cost plus direct contracts for prescriptions and bundled services may yield benefits.
Objectives: This study aimed to (1) explore direct contracting using multistakeholder interviews, (2) compare employer costs and employee copays for 6 months of prescription charges under their pharmacy benefit manager (PBM) with projected costs under a pharmacy direct contract, (3) project pharmacy revenue, costs, and net profit had these prescriptions been processed through the direct contract, and (4) assess employee satisfaction under the direct contract.
Purpose Of Review: Women experience unique life events, for example, pregnancy and lactation, that challenge renal regulation of electrolyte homeostasis. Recent analyses of nephron organization in female vs. male rodent kidneys, revealed distinct sexual dimorphisms in electrolyte transporter expression, abundance, and activity.

While much is known about the machinery of transcellular and paracellular K transport-channels, pumps, co-transporters, and tight-junction proteins-many quantitative aspects of K homeostasis in biological systems remain poorly constrained. Here we present measurements of the stable isotope ratios of potassium (K/K) in three biological systems (algae, fish, and mammals).

Design And Methods: A qualitative descriptive design with interviews was used to gather parental experiences from those who consented to HNS for their adolescent with DS and OSA. Interviews were conducted, audiotaped, and transcribed.
The NCCN Guidelines for Survivorship are intended to help healthcare professionals who work with survivors to ensure that the survivors' complex and varied needs are addressed. The NCCN Guidelines provide screening, evaluation, and treatment recommendations for the consequences of adult-onset cancer and its treatment; recommendations to help promote physical activity, weight management, and immunizations in survivors; and a framework for care coordination. This article summarizes updates to the NCCN Guidelines pertaining to preventive health for cancer survivors, including recommendations about alcohol consumption and vaccinations.

Among prostanoids, prostaglandin E2 and its E-prostanoid receptor 4 receptor (EP4R) have been implicated in blood pressure control. Our previous study found that conditional deletion of EP4R from all tissues in adult mice exacerbates angiotensin II-dependent hypertension, suggesting a powerful effect of EP4R to resist blood pressure elevation.

Here we seek to determine the effects of above canopy N deposition on understorey vascular plants in a jack pine (Pinus banksiana) stand in a five-year experimental study. Aqueous N (ammonium nitrate) was applied four times annually (May through October) via helicopter above the canopy between 2011 and 2015 across a narrow but environmentally relevant N deposition gradient (0, 5, 10, 15, 20 and 25 kg N ha yr).

This qualitative study, embedded within Shamba Maisha (NCT02815579)-a randomized controlled trial (RCT) examining the impact of a multisectoral intervention among farmers living with HIV in western Kenya-sought to explore the influence of perceived access to and control of land on agricultural productivity, investments, and benefits. Thirty in-depth interviews (IDIs) were conducted with purposively sampled men and women, 3 to 6 months after receiving intervention inputs; data were deductively and inductively coded and analyzed.
