BACKGROUND: Patients with hepatocellular carcinoma (HCC) outside Milan criteria (MC) may be candidates for liver transplantation (LT) after successful downstaging. Factors that predict successful downstaging are unclear. We aimed to identify the predictors of successful downstaging of HCC in patients outside MC. METHODS: We performed a retrospective cohort study on consecutive patients with HCC outside MC who received downstaging with locoregional therapy. Clinical and laboratory variables, tumor characteristics including total tumor volume (TTV) and up-to-7 criteria were recorded...

Historically, performing a negative appendectomy (NA) was justified to reduce the incidence of perforation. Furthermore, it is also believed that NA is associated with minimal morbidity and cost. The purpose of this study was to evaluate the frequency, clinical characteristics, and economic implications of NA. We reviewed the inpatient admissions on 274,405 patients who underwent nonincidental appendectomy as their primary procedure from the California State Inpatient Databases (2005-2011). Overall, 96.9 per cent had appendicitis (nonperforated = 73...

Improving patient safety is vital for all hospitals due to increasing public reporting and pay-for-performance reimbursement. Venous thromboembolism (VTE) remains a leading cause of preventable mortality accounting for 5 per cent of inpatient deaths. The purpose of this study was to outline the process of implementing standard VTE prophylactic order sets in a 600-bed academic safety net hospital and assess the resulting change in patient outcomes. Outcomes were assessed by comparing the rate that eligible inpatients receive VTE prophylaxis and the rate of preventable VTE's compared with total VTE's...

BACKGROUND: Efforts to mitigate costs while improving surgical care quality have received much scrutiny. This includes the challenging issue of readmission subsequent to hospital discharge. Initiatives attempting to preclude readmission after surgery require planned and unified efforts extending throughout the perioperative continuum. Patient optimization prior to discharge, enhanced disease monitoring, and seamless coordination of care between hospitals and community providers is integral to this process...

In habitats where resource availability declines during the growing season, selection may favor early-flowering individuals. Under such ephemerally favorable conditions, late-blooming species (and individuals) may be particularly vulnerable to resource limitation of seed production. In California, a region prone to seasonal drought, members of the annual genus Clarkia are among the last to flower in the spring. We compared pollen limitation (PL) of seed set and outcrossing rates between early- and late-flowering individuals in two mixed-mating Clarkia taxa to detect whether flowering time is associated with changes in seed set due to resource depletion, PL, or increased selfing...

BACKGROUND: Revision hip arthroplasty for metal-on-metal arthroplasty (MOMA) in the presence of an adverse local tissue reaction (ALTR) has been associated with compromised outcomes. We hypothesized that revision of MOMA for painful micromotion of the cup, in the absence of ALTR, would have a more favorable outcome. METHODS: We reviewed our database for Durom acetabular shell revision with minimum 24 months (24 months to 8 years) follow-up. Patients with a diagnosis of painful micromotion in the absence of pseudotumor was identified...

The influenza epidemic in 2015-2016 in Russia is characterized by a sharp increase of influenza cases (beginning from the second week of 2016) with increased fatalities. Influenza was confirmed in 20 fatal cases registered among children (0-10 years), in 5 cases among pregnant women, and in 173 cases among elderly people (60 years and older). Two hundred and ninety nine people died from influenza were patients with some chronic problems. The overwhelming majority among the deceased (more than 98%) were not vaccinated against influenza...

Importance: State-specific information about the health burden of smoking is valuable because state-level initiatives are at the forefront of tobacco control. Smoking-attributable cancer mortality estimates are currently available nationally and by cancer, but not by state. Objective: To calculate the proportion of cancer deaths among adults 35 years and older that were attributable to cigarette smoking in 2014 in each state and the District of Columbia. Design, Setting, and Participants: The population-attributable fraction (PAF) of cancer deaths due to cigarette smoking was computed using relative risks for 12 smoking-related cancers (acute myeloid leukemia and cancers of the oral cavity and pharynx; esophagus; stomach; colorectum; liver; pancreas; larynx; trachea, lung, and bronchus; cervix uteri; kidney and renal pelvis; and urinary bladder) from large US prospective studies and state-specific smoking prevalence data from the Behavioral Risk Factor Surveillance System...

OBJECTIVES: Language barriers negatively impact health care access and quality for US immigrants. Latinos are the second largest immigrant group and the largest, fastest growing minority. Health care systems need simple, low cost and accurate tools that they can use to identify physicians with Spanish language competence. We sought to address this need by validating a simple and low-cost tool already in use in a major health plan. DESIGN SETTING PARTICIPANTS: A web-based survey conducted in 2012 among physicians caring for patients in a large, integrated health care delivery system...

E-cigarette use has dramatically increased. While studies have examined adolescents' attitudes towards smoking, few have extended this research to adolescents' attitudes towards e-cigarettes. The goal of this study was to examine adolescents' attitudes regarding e-cigarette ingredients, safety, addictive properties, social norms, accessibility, price, and regulation; and determine whether attitudes differ by past cigarette/e-cigarette use. Participants were 786 9th and 12th graders from California (63.21% females; mean age=16...

JNJ63623872 (formerly known as VX-787) is an inhibitor of influenza A virus polymerases through interaction with the viral PB2 subunit. This interaction blocks the cap-snatching activity of the virus that is essential for virus replication. Previously published work has documented antiviral activity of JNJ63623872 in cell culture and mouse infection studies. In this report, we extend the in vivo observations by comparing the efficacies of JNJ63623872 and oseltamivir in mice infected with influenza A/California/04/2009 (H1N1pdm) and A/Victoria/3/75 (H3N2) viruses...

We present a case of a 57-year-old man who fell while climbing a mountain in California and sustained severe facial trauma. Three firefighters and 2 emergency physicians witnessed the fall and resuscitated the patient. The patient ultimately required a surgical cricothyrotomy performed with a pocket knife and Platypus hydration pack. The physicians made a makeshift positive pressure airway device using the Platypus hydration pack. We believe this is the first case report describing an improvised cricothyrotomy performed in the wilderness using only hiking gear...

Wildlife lead exposure is an increasing conservation threat that is being widely investigated. However, for some areas of the world (e.g., South America) and certain species, research on this subject is still scarce or only local information is available. We analyzed the extent and intensity of lead exposure for a widely distributed threatened species, the Andean Condor (Vultur gryphus). We conducted the study at two different scales: 1) sampling of birds received for rehabilitation or necropsy in Argentina, and 2) bibliographic review and extensive survey considering exposure event for the species' distribution in South America...

The concept of dynamic single-interface hollow fiber membrane liquid-phase microextraction (HF-LPME), where the target analyte was extracted on-line and eluted inside the lumen of the HF membrane, was explored. An ionic liquid containing supported liquid membrane was used for the trace determination of Cr(VI) as a model compound. Since the extraction took place on-line inside the hollow fiber membrane, the mass transfer behavior was described and discussed in comparison with the conventional HF-LPME. The extraction efficiency was improved by a recirculation configuration of the sample solution at relatively high sampling flow rates as a result of the increased effective contact area...
