Oocyte IVM technology is an option for fertility preservation in some groups of patients, such as those with polycystic ovary syndrome, patients with ovarian hyperstimulation syndrome, and for patients with cancer. However, the developmental potential of oocytes from IVM still needs to improve. Several previous studies have reported that lysophosphatidic acid (LPA) promotes glucose metabolism, cumulus cell (CC) expansion, and oocyte nuclear maturation. However, the effect of LPA on oocyte cytoplasmic maturation, particularly mitochondrial function, has rarely been studied and the underlying mechanism is largely unknown, which impedes (pre)clinical applications of LPA. In this study, cumulus-oocyte complexes (COCs) and cumulus-denuded germinal vesicle oocytes (DOs) were treated with various concentrations of LPA during IVM, in the presence or absence of the oxidative stressor cyclophosphamide (CTX). In both normal and CTX-damaged COCs, the 25 μM LPA group exhibited improved CC expansion capacity, a higher nuclear maturation rate, and superior mitochondrial function, compared to no LPA treatment. When the concentration of LPA was over 40 μM, detrimental effects of LPA on oocyte maturation occurred. Compared with COCs, the addition of LPA slightly improved oocyte nuclear and cytoplasmic maturation of DOs, but this was not statistically significant. We observed that LPA promotes the activation of extracellular signal-regulated kinase (ERK)1/2, although this was not statistically significant in DOs. Furthermore, LPA could not reverse the negative effect of CC expansion and mitochondrial function after inactivation of ERK1/2 by U0126. RNA-sequencing and RT-PCR results showed that LPA upregulated several ERK1/2 downstream genes related to CC expansion, such as Areg, Cited4, and Ptgs2. This study demonstrates that LPA improves oocyte quality during IVM through the activation of ERK1/2 pathway CCs and oocytes, which provides evidence for the potential addition of LPA to IVM medium.

The lack of a well-designed prospective study of the determinants of urgent dialysis start led us to investigate its individual- and provider-related factors in patients seeing nephrologists.

CKD-REIN is a prospective cohort study that included 3033 patients with CKD (mean age, 67 years; 65% men; mean estimated glomerular filtration rate (eGFR), 32 mL/min/1.73 m2) from 40 nationally representative nephrology clinics from 2013-16, who were followed annually through 2020. Enfortumab vedotin-ejfv in vivo Urgent-start dialysis was defined as that "initiated imminently or < 48 hours after presentation to correct life-threatening manifestations" according to KDIGO 2018.

Over a 4-year (IQR, 3.0-4.8) median follow-up, 541 patients initiated dialysis with a known start status, 86 (16%) urgently. Five-year risks for the competing events of urgent and nonurgent dialysis start, pre-emptive transplantation, and death were 4%, 17%, 3%, and 15%, respectively. Fluid overload, electrolytic disorders, acute kidney injury, and post-surgery kidney function worsening were the reasons most frequently reported for urgent-start dialysis. Adjusted odds ratios (aOR) for urgent start were significantly higher in patients living alone (2.14; 95% CI, 1.08-4.25), or with low health literacy (2.22; 1.28-3.84), heart failure (2.60; 1.47-4.57), or hyperpolypharmacy (taking > 10 drugs) (2.14; 1.17-3.90), but not with age or lower eGFR at initiation. They were lower in patients with planned dialysis modality (0.46; 0.19-1.10) and more nephrologist visits in the 12 months before dialysis (0.81; 0.70-0.94) for each visit.

This study highlights several patient- and provider-level factors that are important to address to reduce the burden of urgent-start dialysis.

The objective of this study was to examine changes in microbiome diversity and the presence of antibiotic residues (ABR) on three farms that contained a diverse range of animal species pasture-raised poultry (broiler and layer), swine and beef cattle. Total bacterial communities were determined using 16S rRNA microbiome analysis, while specific ARG (sulfonamide [Sul; Sul1] and tetracycline [Tet; TetA]) were enumerated by qPCR. Results indicated that the ARG abundances (Sul1 [P less then 0.05] and TetA [P less then 0.001]) were higher in layer hen manures (16.5 x 10 -4 and 1.4 x 10 -4 µg kg -1, respectively) followed by broiler chickens (2.9 x 10 -4 and 1.7 x 10 -4 µg kg -1, respectively), swine (0.22 x 10 -4 and 0.20 x 10 -4 µg kg -1, respectively) and beef cattle (0.19 x 10 -4 and 0.02 x 10 -4 µg kg -1, respectively). Average fecal TetA ABR tended to be greater (P = 0.09) for broiler chickens (11.4 µg kg -1) than for other animal species (1.8-0.06 µg kg -1), while chlortetracycline, lincomycin, and oxytetracycline ABR were similar among animal species. Furthermore, fecal microbial richness and abundances differed significantly (P less then 0.01) both among farms and specific species of animal. This study indicated that the microbial diversity, ABR, ARG concentrations, and types in feces varied from farm-to-farm and from animal species-to-animal species. Future studies are necessary to perform detailed investigations of the horizontal transfer mechanism of antibiotic resistant microorganisms (ARM) and ARG.

List prices set by manufacturers for brand-name prescription drugs in the US have been increasing faster than inflation, although confidential manufacturer rebates offset some of these increases. Most commercially insured patients pay at least some out-of-pocket costs for prescription drugs, and higher patient spending is associated with lower adherence and worse health outcomes.

To examine whether price changes for brand-name drugs are correlated with changes in patient out-of-pocket spending and whether this association varies by insurance benefit design.

A cohort study of 79 brand-name drugs with available pricing data from January 2015 to December 2017 was conducted, with data obtained from a national commercial insurance claims database.

Change in the list prices set by manufacturers and estimated net prices after rebates among non-Medicaid payers.

Change in median out-of-pocket spending among all patients and stratified by insurance pharmacy benefit design, including high-deductible insurance nding when drug prices increase. Among these patients, there was no evidence that manufacturer rebates to insurers are associated with patients' out-of-pocket spending. Policies to rein in unregulated annual increases in list prices for brand-name drugs may have important consequences for patient out-of-pocket spending.

Some commercially insured patients who pay only prescription drug copayments appear to be insulated from increases in drug prices. However, more than half of patients pay deductibles or coinsurance and may experience substantial increases in out-of-pocket spending when drug prices increase. Among these patients, there was no evidence that manufacturer rebates to insurers are associated with patients' out-of-pocket spending. Policies to rein in unregulated annual increases in list prices for brand-name drugs may have important consequences for patient out-of-pocket spending.

Obtaining voluntary informed consent prior to enrollment in clinical trials is a fundamental ethical requirement.

To assess whether health literacy, contextual factors, or sociodemographic characteristics are associated with perception of voluntariness among parents who had consented for their child's participation in a leukemia therapeutic clinical trial.

This cross-sectional study prospectively enrolled 97 parents of children diagnosed as having leukemia at Rady Children's Hospital San Diego, a large tertiary academic center in California, from 2014 to 2017. Health literacy, contextual factors (acculturation, decisional regret, and satisfaction with informed consent), sociodemographic characteristics, and perception of voluntariness after consenting for a therapeutic clinical trial were measured. Univariable and multivariable regression were used to determine significant associations. The analyses for the present study were conducted from May 2019 to May 2020.

Informed consent for a therapeutic leukpotential role of recruitment interventions tailored to the participant's health literacy level to improve voluntary informed consent in underserved populations.

Among parents of children with newly diagnosed leukemia who had consented for their child's participation in a therapeutic clinical trial, lower perception of voluntariness was significantly associated with lower health literacy. These results suggest that parents with low health literacy may perceive external influences in their decision for their child's participation in clinical trials. This finding highlights the potential role of recruitment interventions tailored to the participant's health literacy level to improve voluntary informed consent in underserved populations.

Financial incentives may improve health by rewarding patients for focusing on present actions-such as medication regimen adherence-that provide longer-term health benefits.

To identify barriers to improving statin therapy adherence and control of cholesterol levels with financial incentives and insights for the design of future interventions.

This qualitative study involved retrospective interviews with participants in a preplanned secondary analysis of a randomized clinical trial of financial incentives for statin therapy adherence. A total of 636 trial participants from several US insurer or employer populations and an academic health system were rank ordered by change in low-density lipoprotein cholesterol (LDLC) levels. Participants with the most LDLC level improvement (high-improvement group) and those with LDLC levels that did not improve (nonimprovement group) were purposively targeted, stratified across all trial groups, for semistructured telephone interviews that were performed from April 1 to84.

Kidney failure risk prediction has implications for disease management, including advance care planning in adults with severe (ie, estimated glomerular filtration rate [eGFR] category 4, [G4]) chronic kidney disease (G4-CKD). Existing prediction tools do not account for the competing risk of death.

To compare predictions of kidney failure (defined as estimated glomerular filtration rate [eGFR] <10 mL/min/1.73 m2 or initiation of kidney replacement therapy) from models that do and do not account for the competing risk of death in adults with G4-CKD.

This prognostic study linked population-based laboratory and administrative data (2002-2017) from 2 Canadian provinces (Alberta and Manitoba) to compare 3 kidney risk models the standard Cox regression, cause-specific Cox regression, and Fine-Gray subdistribution hazard model. Participants were adults with incident G4-CKD (eGFR 15-29 mL/min/1.73 m2). Data analysis occurred between July and December 2020.

The performance of kidney risk models at prespecified times and across categories of baseline characteristics, using calibration, reclassification, and discrimination (for competing risks).
