Academic medicine is in an era of unprecedented and constant change due to fluctuating economies, globalization, emerging technologies, research, and professional and educational mandates. Consequently, academic health science centers (AHSCs) are facing new levels of complexity, constraint, and uncertainty. Currently, AHSC leaders work with competing academic and health service demands and are required to work with and are accountable to a diversity of stakeholders. Given the new challenges and emerging needs, the authors believe the leadership methods and approaches AHSCs have used in the past that led to successes will be insufficient...

Oxidative stress is two sided: Whereas excessive oxidant challenge causes damage to biomolecules, maintenance of a physiological level of oxidant challenge, termed oxidative eustress, is essential for governing life processes through redox signaling. Recent interest has focused on the intricate ways by which redox signaling integrates these converse properties. Redox balance is maintained by prevention, interception, and repair, and concomitantly the regulatory potential of molecular thiol-driven master switches such as Nrf2/Keap1 or NF-κB/IκB is used for system-wide oxidative stress response...

Oxymatrine (OMT), a monosomic alkaloid extracted from the Chinese herb, Sophora flavescens Ait, has long been used as a traditional Chinese medicine for the treatment of inflammatory diseases. The aim of the present study was to investigate the potential anti‑inflammatory effect of OMT, and its modulation on imbalance between regulatory T (Treg) cells and T helper (Th) 17 cells in rats with collagen‑induced arthritis (CIA). Sprague‑Dawley rats were immunized with type II collagen and following a second collagen immunization, the rats were treated with OMT or dexamethasone (DXM) intraperitoneally once a day for 43 days...

Vaccine development is one of the greatest achievements of modern medicine. Vaccines made of live-attenuated pathogens can revert to virulent live strains, which causes safety concerns. On the other hand, the use of purified antigenic components as subunit vaccines is safer, but less effective, as these components induce lower levels of protective immunity. Multiple copy presentation of an antigenic determinant in a well-ordered and well-defined orientation on a nanosized particle can mimic the natural host-pathogen surface interaction to provide antigen stability and immunogenicity similar to that of conventional vaccines with improved safety...

We previously demonstrated that altered activity of lysophosphatidic acid in murine mammary glands promotes tumorigenesis. We have now established and characterized a heterogeneous collection of mouse-derived syngeneic transplants (MDSTs) as preclinical platforms for the assessment of personalized pharmacological therapies. Detailed molecular and phenotypic analyses revealed that MDSTs are the most heterogeneous group of genetically engineered mouse models (GEMMs) of breast cancer yet observed. Response of MDSTs to trametinib, a mitogen-activated protein kinase (MAPK) kinase inhibitor, correlated with RAS/MAPK signaling activity, as expected from studies in xenografts and clinical trials providing validation of the utility of the model...

Prebiotics are selectively fermentable dietary compounds that result in changes in the composition and/or activity of the intestinal microbiota, thus conferring benefits upon host health. In veterinary medicine, commercially available products containing prebiotics have not been well studied with regard to the changes they trigger on the composition of the gut microbiota. This study evaluated the effect of a commercially available nutraceutical containing fructo-oligosaccharides (FOS) and inulin on the fecal microbiota of healthy cats and dogs when administered for 16 days...

BACKGROUND: Failure to follow up and communicate test results to patients in outpatient settings may lead to diagnostic and therapeutic delays. Residents are less likely than attending physicians to report results to patients, and may face additional barriers to reporting, given competing clinical responsibilities. OBJECTIVE: This study aimed to improve the rates of communicating test results to patients in resident ambulatory clinics. METHODS: We performed an internal medicine, residency-wide, pre- and postintervention, quality improvement project using audit and feedback...

BACKGROUND: There is an incomplete understanding of the most effective approaches for motivating residents to adopt guideline-recommended practices for hospital discharges. OBJECTIVE: We evaluated internal medicine (IM) residents' exposure to educational experiences focused on facilitating hospital discharges and compared those experiences based on correlations with residents' perceived responsibility for safely transitioning patients from the hospital. METHODS: A cross-sectional, multi-center survey of IM residents at 9 US university- and community-based training programs in 2014-2015 measured exposure to 8 transitional care experiences, their perceived impact on care transitions attitudes, and the correlation between experiences and residents' perceptions of postdischarge responsibility...

BACKGROUND: Since 2013, the National Resident Matching Program (NRMP) has asked all programs to declare themselves to be "all in" or "all out" for the NRMP. Before this rule was enacted, program directors who were surveyed expressed concerns about what they anticipated with the change, including resources for increased applications and potential delays with residency start times. OBJECTIVE: This study investigated the positive and negative effects of the rule change on recruiting seen from the perspective of internal medicine (IM) program directors...

PURPOSE: Vitamin D is a fascinating and attractive molecule that has gained particular attention in medicine in recent years. Its immunomodulatory and anti-inflammatory potential might resemble the activity of many nature-derived molecules (eg, flavonoids), but its role in biology was selected during a long evolutionary pathway to dampen the damaging effect of cell stress response and of the immune reaction. In this sense, this molecule can be considered an ancient hormone that serves, in its primary role, as a pro-survival agent...

Aims Cardiovascular fixed-dose combination pills, or polypills, may help address the widespread lack of access and adherence to proven medicines. Initiation of polypill-based care typically entails switching from current separately taken medications. Given the heterogeneity in usual care, there is interest in the impact of polypill treatment across different patterns of prior medication regimen. Methods A total of 2004 participants with established cardiovascular disease or estimated 5-year cardiovascular risk of over 15% were randomised to polypill-based treatment (aspirin 75 mg, simvastatin 40 mg, lisinopril 10 mg and either atenolol 50 mg or hydrochlorothiazide 12...

Incorporating "-omics" studies with environmental interactions could help elucidate the biological mechanisms responsible for Traditional Chinese Medicine (TCM) patterns. Based on the authors' own experiences, this review outlines a model of an ideal combination of "-omics" biomarkers, environmental factors, and TCM pattern classifications; provides a narrative review of the relevant genetic and TCM studies; and lists several successful integrative examples. Two integration tools are briefly introduced. The first is the integration of modern devices into objective diagnostic methods of TCM patterning, which would improve current clinical decision-making and practice...

Light is a necessary environmental factor for production of conidia and pigment, formation of stroma, and development of Cordyceps militaris, a well-known edible and medicinal mushroom. In this study, an obvious rhythm loop was observed in certain strains of C. militaris under conditions of alternating 12-hour intervals of dark and light. A possibly related gene, Cmvvd, the homologue of the blue-light photoreceptor of Neurospora crassa, was cloned from the genome of C. militaris. The protein CmVVD is predicted to be 203 amino acids in length and is characterized by the presence of a light, oxygen, or voltage domain...

In recent decades, infertility is one of the health problems worldwide. One of the most crucial events in reproductive period is implantation window (IW). In the time after IW period, the embryo cannot connect to the endometrium; therefore the most critical issue for successful implantation is timely entrance of embryo to the uterine cavity during the IW. Implantation failure is responsible for many cases of infertility and is the most important limiting factor for achieving a successful outcome using the assisted reproductive techniques (ART)...

BACKGROUND: Amyloid beta (Aβ) oligomers play a critical role in the pathogenesis of Alzheimer's disease (AD) and represent a promising target for drug development. Tramiprosate is a small-molecule Aβ anti-aggregation agent that was evaluated in phase III clinical trials for AD but did not meet the primary efficacy endpoints; however, a pre-specified subgroup analysis revealed robust, sustained, and clinically meaningful cognitive and functional effects in patients with AD homozygous for the ε4 allele of apolipoprotein E4 (APOE4/4 homozygotes), who carry an increased risk for the disease...
