The relationship between telomeres, nevi and melanoma is complex. Shorter telomeres have been found to be associated with many cancers and with number of nevi, a known risk factor for melanoma. However, shorter telomeres have also been found to decrease melanoma risk. We performed a systematic analysis of telomere-related genes and tagSNPs within these genes, in relation to the risk of melanoma, dysplastic nevi, and nevus count combining data from four studies conducted in Italy. In addition, we examined whether telomere length measured in peripheral blood leukocytes is related to the risk of melanoma, dysplastic nevi, number of nevi, or …

BACKGROUND: Intimate partner violence (IPV) is prevalent among adolescent and adult women, with significant physical, sexual, and mental health consequences. In 2011, the Institute of Medicine's Clinical Preventive Services for Women consensus report recommended universal screening for violence as a component of women's preventive services; this policy has been adopted by the Health Resources and Services Administration (HRSA). These policy developments require that effective clinic-based interventions be identified, easily implemented, and taken to scale.

METHODS: To foster dialogue about implementing effective interventions, we convened a symposium entitled "Responding to Violence Against Women: Emerging Evidence, Implementation Science, and Innovative Interventions," on …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Necrostatin-1 (Nec-1) is widely used in disease models to examine the contribution of receptor-interacting protein kinase (RIPK) 1 in cell death and inflammation. We studied three Nec-1 analogs: Nec-1, the active inhibitor of RIPK1, Nec-1 inactive (Nec-1i), its inactive variant, and Nec-1 stable (Nec-1s), its more stable variant. We report that Nec-1 is identical to methyl-thiohydantoin-tryptophan, an inhibitor of the potent immunomodulatory enzyme indoleamine 2,3-dioxygenase (IDO). Both Nec-1 and Nec-1i inhibited human IDO, but Nec-1s did not, as predicted by molecular modeling. Therefore, Nec-1s is a more specific RIPK1 inhibitor lacking the IDO-targeting effect. Next, although Nec-1i was ∼100 × …

More than 40 genetic susceptibility loci have been reported for type 2 diabetes (T2D). Recently, the combined effect of genetic variants has been investigated by calculating a genetic risk score. We evaluated 36 genome-wide association study (GWAS) identified SNPs in 2,679 T2D cases and 3322 controls in middle-age Han Chinese. Fourteen SNPs were significantly associated with T2D in analysis adjusted for age, sex and BMI. We calculated two genetic risk scores (GRS) (GRS1 with all the 36 SNPs and GRS2 with the 14 SNPs significantly associated with T2D). The odds ratio for T2D with each GRS point (per risk allele) …

Inla Promotes Dissemination Of Listeria Monocytogenes To The Mesenteric Lymph Nodes During Food Borne Infection Of Mice, Elsa N. Bou Ghanem, Grant S. Jones, Tanya Myers-Morales, Pooja D. Patil, Achmad N. Hidayatullah, Sarah E. F. D'Orazio

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Intestinal Listeria monocytogenes infection is not efficient in mice and this has been attributed to a low affinity interaction between the bacterial surface protein InlA and E-cadherin on murine intestinal epithelial cells. Previous studies using either transgenic mice expressing human E-cadherin or mouse-adapted L. monocytogenes expressing a modified InlA protein (InlA(m)) with high affinity for murine E-cadherin showed increased efficiency of intragastric infection. However, the large inocula used in these studies disseminated to the spleen and liver rapidly, resulting in a lethal systemic infection that made it difficult to define the natural course of intestinal infection. We describe here a …

Obstetrics and Gynecology Faculty Publications

BACKGROUND: Limited evidence suggests that intimate partner violence (IPV) may be associated with poorer cancer outcomes. We hypothesized that timing and type of IPV as well as childhood sexual abuse (CSA) may negatively affect depression, perceived stress, and cancer-related well-being.

METHODS: This was a cross-sectional study of women diagnosed with either breast, cervical, or colorectal cancer in the prior 12 months included in the Kentucky Cancer Registry. Consenting women were interviewed by phone (n=553). Multivariate analysis of covariance (MANCOVA) was used to determine the association between IPV (37% lifetime prevalence) and type, timing, and the range of correlated cancer-related well-being …

Load-Relaxation Properties Of The Human Trunk In Response To Prolonged Flexion: Measuring And Modeling The Effect Of Flexion Angle, Nima Toosizadeh, Maury A. Nussbaum, Babak Bazrgari, Michael L. Madigan

Biomedical Engineering Faculty Publications

Experimental studies suggest that prolonged trunk flexion reduces passive support of the spine. To understand alterations of the synergy between active and passive tissues following such loadings, several studies have assessed the time-dependent behavior of passive tissues including those within spinal motion segments and muscles. Yet, there remain limitations regarding load-relaxation of the lumbar spine in response to flexion exposures and the influence of different flexion angles. Ten healthy participants were exposed for 16 min to each of five magnitudes of lumbar flexion specified relative to individual flexion-relaxation angles (i.e., 30, 40, 60, 80, and 100%), during which lumbar flexion …

Effect Of Genetic Variants, Especially Cyp2c9 And Vkorc1, On The Pharmacology Of Warfarin, Erik Fung, Nikolaos Patsopoulos, Steven Belknap, Daniel O'Rourke, John Robb, Jeffrey L. Anderson, Nicholas W. Shworak, Jason H. Moore

Dartmouth Scholarship

The genes encoding the cytochrome P450 2C9 enzyme (CYP2C9) and vitamin K-epoxide reductase complex unit 1 (VKORC1) are major determinants of anticoagulant response to warfarin. Together with patient demographics and clinical information, they account for approximately one-half of the warfarin dose variance in individuals of European descent. Recent prospective and randomized controlled trial data support pharmacogenetic guidance with their use in warfarin dose initiation and titration. Benefits from pharmacogenetics-guided warfarin dosing have been reported to extend beyond the period of initial dosing, with supportive data indicating benefits to at least 3 months. The genetic effects of VKORC1 and CYP2C9 in …


Nevirapine Hepatotoxicity: Case Report And Discussion, Matt Baichi Oct 2012

Nevirapine Hepatotoxicity: Case Report And Discussion, Matt Baichi

The Medicine Forum

Nevirapine (viramune) is a nonnucleoside reverse transcriptase inhibitor commonly used in combination with other antiretroviral medicines in the treatment of HIV/AIDS. The safety profile of nevirapine, as determined by review of prospective clinical trials, reports rash with an incidence of 16% as the most common side effect. Clinical hepatitis is reported to occur with an incidence of 1%. A review of the literature shows many case reports of nevirapine-induced hepatotoxicity in patients receiving both treatment and prophylaxis for HIV. The purpose of this case report is to stress the importance of early recognition and withdrawal of the offending drug.

Brain and Mind Institute Researchers' Publications

Current research suggests a role for biomedical knowledge in learning and retaining concepts related to medical diagnosis. However, learning may be influenced by other, non-biomedical knowledge. We explored this idea using an experimental design and examined the effects of causal knowledge on the learning, retention, and interpretation of medical information. Participants studied a handout about several respiratory disorders and how to interpret respiratory exam findings. The control group received the information in standard "textbook" format and the experimental group was presented with the same information as well as a causal explanation about how sound travels through lungs in both the …

Department of Neurosurgery Faculty Papers

To improve clinicians' ability to predict outcome after spinal cord injury (SCI) and to help classify patients within clinical trials, we have created a novel prediction model relating acute clinical and imaging information to functional outcome at 1 year. Data were obtained from two large prospective SCI datasets. Functional independence measure (FIM) motor score at 1 year follow-up was the primary outcome, and functional independence (score ≥ 6 for each FIM motor item) was the secondary outcome. A linear regression model was created with the primary outcome modeled relative to clinical and imaging predictors obtained within 3 days of injury. …

Department of Occupational Therapy Faculty Papers

Parents of children with autism frequently report that their children exhibit unusual responses to sensory experiences. Little research is available, however, describing how parents' and children's culture and environment might influence parents' reports of their children's behaviors. This study compared the frequency of parent-reported responses to sensory experiences in children from two countries-Israel and the United States. We administered the Short Sensory Profile to primary caregivers of children with autism spectrum disorders (ASD) and typically developing peers. Results indicate that Israeli parents reported unusual responses to sensory experiences less frequently than U.S. parents for both ASD and typically developing children. …

Sarcopenia, Obesity, And Natural Killer Cell Immune Senescence In Aging: Altered Cytokine Levels As A Common Mechanism, Charles T. Lutz, Lebris S. Quinn Aug 2012

Sarcopenia, Obesity, And Natural Killer Cell Immune Senescence In Aging: Altered Cytokine Levels As A Common Mechanism, Charles T. Lutz, Lebris S. Quinn

Pathology and Laboratory Medicine Faculty Publications

Human aging is characterized by both physical and physiological frailty. A key feature of frailty, sarcopenia is the age-associated decline in skeletal muscle mass, strength, and endurance that characterize even the healthy elderly. Increases in adiposity, particularly in visceral adipose tissue, are almost universal in aging individuals and can contribute to sarcopenia and insulin resistance by increasing levels of inflammatory cytokines known collectively as adipokines. Aging also is associated with declines in adaptive and innate immunity, known as immune senescence, which are risk factors for cancer and all-cause mortality. The cytokine interleukin-15 (IL-15) is highly expressed in skeletal muscle tissue …
