AbstractBackgroundPheochromocytoma with synchronous ipsilateral adrenal cortical adenoma (PSCA) may present with mixed clinical, biochemical, and radiological features characteristic to each neoplasm subtype. MethodsAll patients with a pathological diagnosis of pheochromocytoma were evaluated for an ipsilateral cortical adenoma from 1994 through 2015. Retrospectively extracted data included indications for adrenalectomy, diagnostic workup (biochemical and radiographic), operative characteristics, pathological findings, and postoperative complications. ResultsSixteen of 413 patients (4%) undergoing adrenalectomy for pheochromocytoma had a PSCA. Median patient age was 57.7 years (IQR 50.1, 63.1); 50% were male. On imaging, 75% of the adrenal neoplasms were found incidentally and only 50% were reported to have a synchronous ipsilateral neoplasm based on imaging findings. Clinically important cortical hormone secretion was diagnosed in 38% of these patients; 25% had glucocorticoid secretory autonomy; and 13% had primary aldosteronism. ConclusionPhysicians should be aware that adrenal neoplasms with mixed diagnostic findings may represent PSCA. Evaluation should be performed on this co‐occurrence to prevent perioperative complications from resection of an unexpected secretory cortical neoplasm.

In 2010, Senate Bill 1309 included language to repeal an existing Arizona law that enables minors younger than 18 years of age to seek diagnosis and treatment of sexually transmitted diseases (STDs) without parental consent. Numerous implications were identified that would have stemmed from parental consent provisions originally proffered in Senate Bill 1309. These implications included diminished access to essential health services among minors, exacerbated existing health disparities, increased health-care spending costs, and thwarted efforts to curb the spread of STDs. Lastly, minors would have been deprived of existing privacy protections concerning their STD-related medical information. This case study describes how collaborative advocacy efforts resulted in the successful amendment of Senate Bill 1309 to avert the negative sexual and reproductive health outcomes among adolescents stemming from the potential repeal of their existing legal right to seek STD treatment without parental consent.

Exploding targets are marketed for their ability to indicate long-range marksmanship by detonating upon high velocity impact. The Internet has popularized recreational use of these targets outside of the scope of their intended design. We present a case of a 47-year-old man who was a bystander during recreational use of exploding targets. A .300 Winchester Magnum rifle was used to detonate an exploding target, on top of which was placed a fire extinguisher inside an aluminum pipe. The decedent was struck in the abdomen by a fragment of aluminum and collapsed. Despite emergency efforts at the scene, he was pronounced dead. Scene investigation revealed aluminum fragments throughout the blast radius. External examination and postmortem radiograph showed an entry wound of the left mid-abdomen without evidence of retained shrapnel. The autopsy findings included a hemoperitoneum due to transection of the right common iliac artery and inferior vena cava. A 10.6 g fragment of aluminum was recovered from within the abdomen. This case illustrates a dangerous misuse of exploding targets that has been popularized in the media. It also exemplifies a potential pitfall of a negative radiograph, despite the presence of metal shrapnel, because of the radiolucency of aluminum.

ObjectiveThis study aims to provide effect size estimates of the impact of two cognitive rehabilitation interventions provided to patients with mild cognitive impairment: computerized brain fitness exercise and memory support system on support partners' outcomes of depression, anxiety, quality of life, and partner burden.MethodsA randomized controlled pilot trial was performed.ResultsAt 6 months, the partners from both treatment groups showed stable to improved depression and anxiety scores, while partners in an untreated control group showed worsening depression and anxiety over 6 months. There were no statistically significant differences on quality of life or burden outcomes in this small pilot trial; however, effect sizes were moderate, suggesting that the sample sizes in this pilot study were not adequate to detect statistical significance.ConclusionEither form of cognitive rehabilitation may help partners' mood or anxiety, compared with providing no treatment. However, effect size estimates related to other partner outcomes (i.e., burden, quality of life) suggest that follow‐up efficacy trials will need sample sizes of at least 30–100 people per group to accurately determine significance.

Objective. HIV and sexually transmitted disease (STD) surveillance patterns in Arizona suggested the need for integrated data analyses to identify trends. Methods. We compiled all HIV/AIDS cases diagnosed from 1998 to 2008 that were reported in Arizona and syphilis or gonorrhea cases diagnosed from 1998 to 2008 in Arizona. We used deterministic matching to identify individuals who were diagnosed with HIV and one or more STDs, and calculated time intervals between diagnoses. Results. Of 23,940 people with HIV/AIDS reported from 1998 to 2008, 1,899 (2.6%) had at least one syphilis or gonorrhea diagnosis from 1998 to 2008. Approximately 85% of these cases reported male-to-male sexual contact. Among males with syphilis, HIV coinfection increased from 0.5% in 1998 to 29.1% in 2008. Among males with gonorrhea, HIV coinfection increased from 2.0% in 1998 to 3.1% in 2008. Among HIV cases diagnosed from 2004 to 2008 and reported with at least one syphilis or gonorrhea diagnosis, the majority of syphilis cases (76.1%) were diagnosed at or after HIV diagnosis, whereas a majority of gonorrhea cases (54.9%) were diagnosed prior to HIV diagnosis. Conclusion. Use of the deterministic matching method identified increases in STD infections among HIV-infected people. The routine performance of this cross-matching method may be a useful tool in identifying these high-risk individuals so that targeted partner services and appropriate care referrals may be used in a timely fashion.

Genome-wide association studies have identified >50 common variants associated with kidney function, but these variants do not fully explain the variation in eGFR. We performed a two-stage meta-analysis of associations between genotypes from the Illumina exome array and eGFR on the basis of serum creatinine (eGFRcrea) among participants of European ancestry from the CKDGen Consortium ( n Stage1 : 111,666; n Stage2 : 48,343). In single-variant analyses, we identified single nucleotide polymorphisms at seven new loci associated with eGFRcrea ( PPM1J , EDEM3, ACP1, SPEG, EYA4, CYP1A1 , and ATXN2L ; P Stage1 <3.7×10 −7 ), of which most were common and annotated as nonsynonymous variants. Gene-based analysis identified associations of functional rare variants in three genes with eGFRcrea, including a novel association with the SOS Ras/Rho guanine nucleotide exchange factor 2 gene, SOS2 ( P =5.4×10 −8 by sequence kernel association test). Experimental follow-up in zebrafish embryos revealed changes in glomerular gene expression and renal tubule morphology in the embryonic kidney of acp1- and sos2 -knockdowns. These developmental abnormalities associated with altered blood clearance rate and heightened prevalence of edema. This study expands the number of loci associated with kidney function and identifies novel genes with potential roles in kidney formation.

Key Points The combination of ixazomib and dexamethasone has clinical activity in patients with relapsed and or refractory multiple myeloma. Higher dose of ixazomib leads to improved response rates but with higher rates of treatment related adverse events.

Abstract Background: Common cancers develop through a multistep process often including inherited susceptibility. Collaboration among multiple institutions, and funding from multiple sources, has allowed the development of an inexpensive genotyping microarray, the OncoArray. The array includes a genome-wide backbone, comprising 230,000 SNPs tagging most common genetic variants, together with dense mapping of known susceptibility regions, rare variants from sequencing experiments, pharmacogenetic markers, and cancer-related traits. Methods: The OncoArray can be genotyped using a novel technology developed by Illumina to facilitate efficient genotyping. The consortium developed standard approaches for selecting SNPs for study, for quality control of markers, and for ancestry analysis. The array was genotyped at selected sites and with prespecified replicate samples to permit evaluation of genotyping accuracy among centers and by ethnic background. Results: The OncoArray consortium genotyped 447,705 samples. A total of 494,763 SNPs passed quality control steps with a sample success rate of 97% of the samples. Participating sites performed ancestry analysis using a common set of markers and a scoring algorithm based on principal components analysis. Conclusions: Results from these analyses will enable researchers to identify new susceptibility loci, perform fine-mapping of new or known loci associated with either single or multiple cancers, assess the degree of overlap in cancer causation and pleiotropic effects of loci that have been identified for disease-specific risk, and jointly model genetic, environmental, and lifestyle-related exposures. Impact: Ongoing analyses will shed light on etiology and risk assessment for many types of cancer. Cancer Epidemiol Biomarkers Prev; 26(1); 126–35. ©2016 AACR.
