In recent decades, there has been considerable worldwide progress in the treatment of gastric cancer. Gastrectomy with a modified D2 lymphadenectomy (sparing the distal pancreas and spleen) has increasingly gained acceptance as a preferable standard surgical approach among surgeons in the East and the West. Despite growing consensus significant differences still exist in surgical techniques in clinical trials and clinical practices secondary to variations in epidemiology, clinicopathologic features, and surgical outcomes among geographic regions...

Ryan P Merkow, Deborah Korenstein, Rubaya Yeahia, Peter B Bach, Shrujal S Baxi
Importance: Primary care clinicians, who are increasingly responsible for caring for the growing population of cancer survivors, may be unfamiliar with appropriate cancer surveillance strategies. Clinical practice guidelines can inform cancer follow-up care and surveillance testing. Vague recommendations and inconsistencies among guidelines can lead to overuse and underuse of health care resources and have a negative impact on cost and quality of survivorship care. Objective: To examine the specificity and consistency of recommendations for surveillance after active treatment across cancer guidelines...

If statesmanship can be characterized as a bed rock of principles, a strong moral compass, a vision, and an ability to articulate and effect that vision, then the fortitude, tenacity, imperturbability, and resilience of William Crawford Gorgas cannot be overestimated. As Chief Sanitary Officer in Cuba and as Chief Medical Officer in Panama, he actualized strategies to eradicate the vectors of yellow fever and malaria. His superiors initially pigeonholed his requisitions, refused to provide him with any authority, and clamored for his dismissal...

Noninvasive prenatal screening using cell-free DNA, which analyzes placental DNA circulating in maternal blood to provide information about fetal chromosomal disorders early in pregnancy and without risk to the fetus, has been hailed as a potential "paradigm shift" in prenatal genetic screening. Commercial provision of cell-free DNA screening has contributed to a rapid expansion of the tests included in the screening panels. The tests can include screening for sex chromosome anomalies, rare subchromosomal microdeletions and aneuploidies, and most recently, the entire fetal genome...

Incremental hemodialysis has been examined as a viable hemodialysis regimen for selected end-stage renal disease (ESRD) patients. Preservation of residual kidney function (RKF) has been the driving impetus for this approach given its benefits upon the survival and quality of life of dialysis patients. While clinical practice guidelines recommend an incremental start of dialysis in peritoneal dialysis patients with substantial RKF, there remains little guidance with respect to incremental hemodialysis as an initial renal replacement therapy regimen...

Zika virus (ZIKV), a mosquito-borne positive-stranded RNA virus of the family Flaviviridae (genus Flavivirus), is now causing an unprecedented large-scale outbreak in the Americas. Historically, ZIKV spread eastward from equatorial Africa and Asia to the Pacific Islands during the late 2000s to early 2010s, invaded the Caribbean and Central and South America in 2015, and reached North America in 2016. Although ZIKV infection generally causes no symptoms or only a mild self-limiting illness, it has recently been linked to a rising number of severe neurological diseases, including microcephaly and Guillain-Barré syndrome...

INTRODUCTION: Despite the existence of a number of severity-of-illness classifications for other areas of medicine, toxicology research lacks a well-accepted method for assessing the severity of poisoning. The Poisoning Severity Score (PSS) was developed in the 1990s in Europe as a scoring system for poisonings reported to a poison center in order to describe a patient's most severe symptomatology. We reviewed the literature to describe how the PSS is utilized and describe its limitations...

Both the incidence and prevalence of inflammatory bowel disease (IBD) is increasing globally; in the industrialized world up to 0.5% of the population are affected and around 4.2 million individuals suffer from IBD in Europe and North America combined. Successful engraftment in experimental colitis models suggests that intestinal stem cell transplantation could constitute a novel treatment strategy to re-establish mucosal barrier function in patients with severe disease. Intestinal stem cells can be grown in vitro in organoid structures, though only a fraction of the cells contained are stem cells with regenerative capabilities...

Disruption of continuous retention in care (discontinuity) is associated with HIV disease progression. We examined sex, race, and HIV risk disparities in discontinuity after antiretroviral therapy (ART) initiation among patients in North America. Adults (≥18 years of age) initiating ART from 2000 to 2010 were included. Discontinuity was defined as first disruption of continuous retention (≥2 visits separated by >90 days in the calendar year). Relative hazard ratio (HR) and times from ART initiation until discontinuity by race, sex, and HIV risk were assessed by modeling of the cumulative incidence function (CIF) in the presence of the competing risk of death...

Heart failure (HF) is a common cause of death and disability and a major economic burden in industrialized nations. Heart disease remains the leading cause of death in North America, with ischemic and hypertensive heart disease as the leading cause of HF. Various basic and clinical studies have established the role of an activated renin-angiotensin (Ang) system and Ang II generation in the progression of HF. Inhibition of an activated renin-Ang system using Ang-converting enzyme inhibitors, Ang II type 1 receptor blockers, and mineralocorticoid receptors antagonists have shown clinical benefits in patients with HF, although, largely limited to HF with reduced ejection fraction (HF-rEF)...

BACKGROUND: EOX (epirubicin, oxaliplatin, Xeloda; capecitabine) and FOLFOX4 (5-fluorouracil (5-FU), leucovorin, oxaliplatin) are the common chemotherapy regimens used in the treatment of advanced gastric cancer (aGC) in Hong Kong. This study aimed to compare the costs of these therapies for aGC patients from both the healthcare and societal perspectives. It should be noted that, while FOLFOX4 is routinely administered in an outpatient setting in North America and Europe, inpatient setting is adopted in Hong Kong instead, incurring hospitalization cost as a result...
