Epstein-Barr virus (EBV) persists in nasopharyngeal (NPC) and gastric carcinomas (EBVaGC) in a tightly latent form. Cytolytic virus activation (CLVA) therapy employs gemcitabine and valproic acid (GCb+VPA) to reactivate latent EBV into the lytic phase and antiviral valganciclovir to enhance cell death and prevent virus production. CLVA treatment has proven safe in phase-I/II trials with promising clinical responses in patients with recurrent NPC. However, a major challenge is to maximize EBV lytic reactivation by CLVA...

BACKGROUND: Black and Latino minorities have traditionally had poorer access to primary care than non-Latino Whites, but these patterns could change with the Affordable Care Act (ACA). To guide post-ACA efforts to address mental health service disparities, we used a nationally representative sample to characterize baseline race-, ethnicity-, and nativity-associated differences in mental health services in the context of primary care. METHODS: Data were obtained from the Medical Expenditures Panel Survey (MEPS), a two-year panel study of healthcare use, satisfaction with care, and costs of services in the United States (US)...

Shooting in biathlon competitions substantially influences final rankings, but the predictability of hits and misses is unknown. The aims of the current study were A) to explore factors influencing biathlon shooting performance and B) to predict future hits and misses. We explored data from 118,300 shots from 4 seasons and trained various machine learning models before predicting 34,340 future shots (in the subsequent season). A) Lower hit rates were discovered in the sprint and pursuit disciplines compared to individual and mass start (P < 0...

OBJECTIVE: Lifetime depression and depression around the time of an acute coronary syndrome event have been associated with poor cardiac outcomes. Our study sought to examine the persistence of this association, especially given modern cardiac medicine's successes. METHODS: For 332 patients admitted for an acute coronary syndrome, a baseline interview assessed major depression status, and psychological measures were administered. At 1 and 12 months post-acute coronary syndrome event, telephone interviews collected rates of hospital readmission and/or death and major depression status, while biomarker information was examined using medical records...

OBJECTIVE: Although fibrinolytic therapy is an upcoming treatment for intracerebral haemorrhage (ICH), standard guidelines are lacking, and some clinical issues persist. Here, we used our recently devised clot model of ICH to systematically analyse effects of irrigation and cerebrospinal fluid (CSF) on fibrinolysis. METHODS: In vitro clots of human blood (25 ml) were generated and a catheter irrigation system was applied to deliver fluid/treatment. Clots were weighed before and after treatment and compared to rtPA treatment alone...

BACKGROUND: The association of hospital teaching status and overall expenditures has not been studied among patients undergoing hepato-pancreato-biliary (HPB) surgery. We sought to define the impact of hospital teaching intensity on payments and charges associated with (HPB) surgery from the payer perspective. METHODS: Surgical patients undergoing HPB procedures were identified using 2013-2015 Medicare Provider Analysis and Review (MEDPAR) data. Hospital teaching intensity was categorized based on hospital resident-to-bed ratio: non-teaching (NTH: 0), minor teaching (minor-TH: 0-0...

The sensorimotor system prefers sway velocity information when maintaining upright posture. Sway velocity has a unique characteristic of being persistent on a short time-scale and anti-persistent on a longer time-scale. The time where the transition from persistence to anti-persistence occurs provides information about how sway velocity is controlled. It is, however, not clear what factors affect shifts in this transition point. This research investigated postural responses to support surface movements of different temporal correlations and movement velocities...

Water analysis has been an important area since the beginning of analytical chemistry. The focus though has shifted substantially: from minerals and the main constituents of water in the time of Carl Remigius Fresenius to a multitude of, in particular, organic compounds at concentrations down to the sub-nanogram per liter level nowadays. This was possible only because of numerous innovations in instrumentation in recent decades, drivers of which are briefly discussed. In addition to the high demands on sensitivity, high throughput by automation and short analysis times are major requirements...

Persistent wound drainage after total joint arthroplasty can potentiate periprosthetic joint infection. Although current recommendations are to treat persistent wound drainage with surgical debridement, we believe nonoperative treatment may be successful in selected patients. We performed a retrospective analysis of 25 persistently draining hip and knee arthroplasty wounds treated with a protocol consisting of a combination of surgical site aspiration, closure of open wound edges, cessation of anticoagulants, activity modification, and antibiotics (in select patients)...

Aging is a complex process that results from a combination of environmental, genetic, and epigenetic factors. A chronic pro-inflammatory status is a pervasive feature of aging. This chronic low-grade inflammation occurring in the absence of overt infection has been defined as "inflammaging" and represents a significant risk factor for morbidity and mortality in the elderly. The low-grade inflammation persists even after reversing pro-inflammatory stimuli such as LDL cholesterol and the renin-angiotensin system (RAS)...

Muscular dystrophies have always been marginalized culturally and socially, particularly in underdeveloped and developing countries. Pakistan is facing significant dearth of "appropriately" trained neurologists and neuromuscular pathologists. A careful and methodical link between clinical, pathological and molecular analysis must be established before making a diagnosis in such cases. Increased collaboration between local and international neurology societies may add value to collaborative neuromuscular research and education in Pakistan, both in community and health sectors...

Purpose: The number of simultaneous liver-kidney transplants (SLKT) performed in the USA has been rising. The Organ Procurement and Transplantation Network implemented a new policy governing SLKT that specifies eligibility criteria for candidates to receive a kidney with a liver, and creates a kidney waitlist "safety net" for liver recipients with persistent renal failure after transplant. This review explores potential impacts for liver patients and the kidney waitlist. Recent Findings: Factors that have contributed to the rise in SLKT including Model for End-stage Liver Disease (MELD)-based allocation, regional sharing for high MELD candidates, and the rising incidence of non-alcoholic steatohepatitis will continue to increase the number of liver transplant candidates with concurrent renal insufficiency...

Isolated landscapes largely shaped by aeolian processes can occur on Earth, while the majority of Mars' recent history has been dominated by wind-driven activity. Resultantly, Martian landscapes often exhibit large-scale aeolian features, including yardang landforms carved from sedimentary-layered deposits. High-resolution orbital monitoring has revealed that persistent bedform activity is occurring with dune and ripple migration implying ongoing abrasion of the surface. However, little is known about the interaction between dunes and the topography surrounding them...
