Hereditary vitamin D resistant rickets (HVDRR) case series: phenotype, genotype, conventional treatment, and adjunctive cinacalcet therapy.

Introduction: Hereditary vitamin D resistant rickets (HVDRR) is a rare autosomal recessive disorder marked by end-organ resistance of 1,25-dihydroxyvitamin D secondary to various mutations in the vitamin D receptor gene. The currently accepted treatment modality involves bypassing the affected receptors in the gut with high-dose intravenous calcium. In a few limited case reports, cinacalcet, a calcimimetic, has been used as an adjunctive therapy.

Investigating the Role of Non-Coding RNA in Non-Alcoholic Fatty Liver Disease.

Non-coding RNAs (ncRNAs) are RNA molecules that do not code for protein but play key roles in regulating cellular processes. NcRNAs globally affect gene expression in diverse physiological and pathological contexts. Functionally important ncRNAs act in chromatin modifications, in mRNA stabilization and translation, and in regulation of various signaling pathways.

Design: Prospective, cross-sectional.

Risk factors for retransplant kidney recipients: relisting and outcomes from patients' primary transplant.

As of November 2013, 14.5% of the waitlist for a donor kidney comprised patients awaiting a retransplant. We performed a retrospective cohort study of 11,698 adult solitary kidney recipients using national Scientific Registry of Transplant Recipients data transplanted between 2002 and 2011.

Hospitalizations following living donor nephrectomy in the United States.

Background And Objectives: Living donors represented 43% of United States kidney donors in 2012. Although research suggests minimal long-term consequences of donation, few comprehensive longitudinal studies for this population have been performed. The primary aims of this study were to examine the incidence, risk factors, and causes of rehospitalization following donation.

Comorbidity burden and perioperative complications for living kidney donors in the United States.

Background And Objectives: Since 1998, 35% of kidney transplants in the United States have been derived from living donors. Research suggests minimal long-term health consequences after donation, but comprehensive studies are limited. The primary objective was to evaluate trends in comorbidity burden and complications among living donors.

Prominent impact of community risk factors on kidney transplant candidate processes and outcomes.

Numerous factors impact patients' health beyond traditional clinical characteristics. We evaluated the association of risk factors in kidney transplant patients' communities with outcomes prior to transplantation. The primary exposure variable was a community risk score (range 0-40) derived from multiple databases and defined by factors including prevalence of comorbidities, access and quality of healthcare, self-reported physical and mental health and socioeconomic status for each U.

The prognostic value of kidney transplant center report cards.

SRTR report cards provide the basis for quality measurement of US transplant centers. There is limited data evaluating the prognostic value of report cards, informing whether they are predictive of prospective patient outcomes. Using national SRTR data, we simulated report cards and calculated standardized mortality ratios (SMR) for kidney transplant centers over five distinct eras.

The impact of deceased donor kidney risk significantly varies by recipient characteristics.

As of May 2012, over 92 000 patients were awaiting a solitary kidney transplant in the United States and new waitlist registrations have been rising for over a decade. The decreasing availability of donor organs makes it imperative that organ allocation be as efficient and effective as possible. We performed a retrospective cohort study of adult recipients in the United States (n=109 392) using Scientific Registry of Transplant Recipients data.

Impact of psychiatric and social characteristics on HIV sexual risk behavior in Puerto Rican women with severe mental illness.

Background: Latinos in the United States have been identified as a high-risk group for depression, anxiety, and substance abuse. HIV/AIDS has disproportionately impacted Latinos. Review findings suggest that HIV-risk behaviors among persons with severe mental illness (SMI) are influenced by a multitude of factors including psychiatric illness, cognitive-behavioral factors, substance use, childhood abuse, and social relationships.

Comparing two approaches to acquiring HIV-risk data from Puerto Rican women with severe mental illness.

Renewed interest has been expressed by researchers in mixed-method assessment that employs both quantitative and qualitative techniques in an expansive style that utilizes a variety of tactics to address research questions. Participants consisted of Puerto Rican women with severe mental illness living in Cuyahoga County, Ohio. The women were shadowed over a 2-year period to observe and verify behaviors that were self-reported using standardized instruments in semi-structured interviews.

Social closeness increases salivary progesterone in humans.

We examined whether interpersonal closeness increases salivary progesterone. One hundred and sixty female college students (80 dyads) were randomly assigned to participate in either a closeness task with a partner versus a neutral task with a partner. Those exposed to the closeness induction had higher levels of progesterone relative to those exposed to the neutral task.

How to play to your strengths.

Most feedback accentuates the negative. During formal employee evaluations, discussions invariably focus on "opportunities for improvement," even if the overall evaluation is laudatory. No wonder most executives--and their direct reports--dread them.

Reduced DNA-dependent protein kinase activity is associated with lung cancer.

Reduced DNA repair capacity of carcinogen-induced DNA damage is now thought to significantly influence inherent susceptibility to lung cancer. DNA-dependent protein kinase (DNA-PK) is a serine-threonine kinase activated by the presence of double-strand breaks in DNA that appears to play a major role in non-homologous recombination and transcriptional control. The purpose of this study was to determine whether DNA-PK activity varies among individuals and how this affects lung cancer risk.

Frequency of trisomy 20 in nonmalignant bronchial epithelium from lung cancer patients and cancer-free former uranium miners and smokers.

Lung cancer is the leading cause of cancer-related deaths. The development of sensitive screening methods to identify at-risk individuals before emergence of clinical disease would permit early intervention that could decrease this mortality. Our previous studies have shown that cells with trisomy 7 can be detected in bronchial epithelium from cancer-free smokers and former uranium miners.

Detection of trisomy 7 in nonmalignant bronchial epithelium from lung cancer patients and individuals at risk for lung cancer.

Early identification and subsequent intervention are needed to decrease the high mortality rate associated with lung cancer. The examination of bronchial epithelium for genetic changes could be a valuable approach to identify individuals at greatest risk. The purpose of this investigation was to assay cells recovered from nonmalignant bronchial epithelium by fluorescence in situ hybridization for trisomy of chromosome 7, an alteration common in non-small cell lung cancer.
