BACKGROUND Treatment with DAAs before deceased donor liver transplantation has been shown to be an effective strategy to prevent post-transplant HCV recurrence, with a 95% cure-rate among individuals who achieve undetectable HCV VL for ≥30 days pre- transplant. This strategy has not been evaluated in LDLT. MATERIAL AND METHODS We evaluated outcomes in LDLT recipients treated with DAAs pre-transplant and bridged with 4 weeks of post-transplant SOF. All cases of LDLT at Johns Hopkins (1/1/2014-3/1/15) were retrospectively reviewed...

The cell division cycle is the process by which eukaryotic cells replicate their chromosomes and partition them to two daughter cells. To maintain the integrity of the genome, proliferating cells must be able to block progression through the division cycle at key transition points (called 'checkpoints'), if there have been problems in the replication of the chromosomes or their biorientation on the mitotic spindle. These checkpoints are governed by protein-interaction networks, composed of phase-specific cell-cycle activators and inhibitors...

Limited knowledge currently exists on the disparity in pediatric leukemia relapse. This study compared the risk of pediatric leukemia relapse between Hispanic and non-Hispanic Whites. Study participants were children (<20 years) diagnosed with leukemia from January 2006 to December 2014 at the Johns Hopkins All Children's Hospital, St. Petersburg, Florida. Hazard ratios and 95% confidence intervals for relapse-free survival were calculated using adjusted Cox regression. The study included 35 Hispanic and 94 non-Hispanic Whites...

Carboxylesterase (CBE)-mediated metabolic resistance to organophosphate and carbamate insecticides is a major problem for the control of insect disease vectors, such as the mosquito. The most common mechanism involves overexpression of CBEs that bind to the insecticide with high affinity, thereby sequestering them before they can interact with their target. However, the absence of any structure for an insecticide-sequestering CBE limits our understanding of the molecular basis for this process. We present the first structure of a CBE involved in sequestration, Cqestβ21, from the mosquito disease vector, Culex quinquefasciatus...

REVIEW
Emily Rohde, Elizabeth Domm
AIM AND OBJECTIVES: To review current literature about nurses' clinical reasoning practices that support safe medication administration. BACKGROUND: The literature about medication administration frequently focuses on avoiding medication errors. Nurses' clinical reasoning used during medication administration to maintain medication safety receives less attention in the literature. As health care professionals, nurses work closely with patients, assessing and intervening to promote mediation safety prior to, during and after medication administration...

Treatment sequences for the multisymptomatic child with bipolar disorder are not adequately described or based on a systematic clinical trial database, and systems for longitudinal tracking of symptoms are rarely utilized. We present a patient whose symptoms of depression, anxiety, attention-deficit/hyperactivity disorder, oppositional behavior, and mania are rated by a parent and plotted on a weekly basis in the Child Network under a Johns Hopkins Institutional Review Board-approved protocol. This 9-year-old girl remained inadequately responsive to lithium or risperidone...

Sprint intensity interval training (SIT) is reported to improve blood glucose control and may be a useful public health tool. The sirtuins and associated genes are emerging as key players in blood glucose control. This study investigated the interplay between the sirtuin/NAD system and individual variation in insulin sensitivity responses after SIT in young healthy individuals. Before and after 4 weeks of SIT body mass and fat percentage were measured and oral glucose tolerance tests (OGTT) performed in 20 young healthy participants (7 females)...

Alzheimer's disease (AD) is a uniquely human brain disorder characterized by the accumulation of amyloid-beta protein (Aβ) into extracellular plaques, neurofibrillary tangles (NFT) made from intracellular, abnormally phosphorylated tau, and selective neuronal loss. We analyzed a large group of aged chimpanzees (n = 20, age 37-62 years) for evidence of Aβ and tau lesions in brain regions affected by AD in humans. Aβ was observed in plaques and blood vessels, and tau lesions were found in the form of pretangles, NFT, and tau-immunoreactive neuritic clusters...

: The field of Endocrine Surgery is linked to extraordinary contributions made by Hopkins leaders in surgery including William Stewart Halsted, Harvey Cushing, and John L Cameron. Halsted's contributions to the anatomic basis of thyroid and parathyroid surgery were based on his experimental and clinical work performed at Johns Hopkins Hospital. Halsted's disciple, Harvey Cushing, created the field of modern neurosurgery and recognized the disease and syndrome that are immortalized with his name. The Halstedian principles promulgated and transmitted by John L Cameron to subsequent generations of endocrine surgeons at Hopkins have transformed the field of Endocrine Surgery with the stamp of Johns Hopkins Hospital...

BACKGROUND: Acute kidney injury (AKI), which is common among HIV-positive individuals, may contribute to the excess burden of chronic kidney disease (CKD) in this patient population; however, conventional clinical methods to detect AKI do not capture kidney injury sufficiently early to prevent irreversible damage. Further, large observational and interventional studies of AKI generally exclude HIV-positive persons in spite of their disproportionate risk. METHODS: The Predictors of Acute Renal Injury Study (PARIS) is a prospective observational cohort study among HIV-positive individuals established to determine the ability of candidate kidney injury biomarkers to predict future hospitalized clinical AKI, to characterize hospitalized subclinical AKI, and to discern the risk of progressive kidney disease following subclinical and clinical AKI...

Mucoepidermoid carcinoma (MEC) is the most common salivary gland malignancy. Recent studies have shown that most MECs harbor gene fusions involving MAML2-an alteration that appears to be specific for MEC, a finding that could be diagnostically useful. While most cases of MEC are histologically straightforward, uncommon variants can cause considerable diagnostic difficulty. We present 2 variants of MEC for which MAML2 studies were crucial in establishing a diagnosis: a previously undescribed ciliated variant, and the recently described Warthin-like variant...

The oral cavity and oropharynx have historically been viewed as a single anatomic compartment of the head and neck. The practice of combining the oral cavity and oropharynx has recently been revised, largely owing to the observation that human papillomavirus (HPV)-related carcinogenesis has a strong predilection for the oropharynx but not the oral cavity. The purpose of this study was to determine whether HPV is evenly distributed across squamous cell carcinomas of the oropharynx including those sites that do not harbor tonsillar tissues such as the soft palate...

BACKGROUND: Walter E. Dandy (1886-1946) was an outstanding neurosurgeon who spent his entire career at the Johns Hopkins Hospital. After graduating from medical school in 1910, he completed a research fellowship in the Hunterian laboratory with Harvey Cushing and then joined the Department of Surgery as resident, rising to the rank professor in 1931. Dandy made several contributions that helped building the neurosurgical specialty, most famously the introduction of pneumo-ventriculography to image brain lesions for which he received a Nobel prize nomination...

Decreasing biomedical research support over the past decade has driven many talented young scientists to seek careers outside academia. In 2011, the Department of Neurology at Johns Hopkins University School of Medicine developed an internal grant review program (IGRP) to systematically review career development awards (CDAs) and research grants (e.g., R01s) for junior investigators prior to NIH submission. With IGRP implementation, we observed significant increases in the number of CDAs and R-grants awarded to junior investigators...

This paper presents an integrated modelling approach for value assessments, focusing on resource recovery from waste. The method tracks and forecasts a range of values across environmental, social, economic and technical domains by attaching these to material-flows, thus building upon and integrating unidimensional models such as material flow analysis (MFA) and lifecycle assessment (LCA). We argue that the usual classification of metrics into these separate domains is useful for interpreting the outputs of multidimensional assessments, but unnecessary for modelling...
