Perceived similarity of other customers on service experience

This study aims to examine how a mere appearance of other similar customers will influence the perceived service quality of a potential customer. This research involves two experimental studies. Findings shows that if potential customers perceive other customers to be similar (vs. dissimilar) in a hospitality setting with regard to age, they will have more favorable perceptions toward the service quality and have a higher purchase intention. However, the positive impact of the similarity in age cohort can override the negative impact of dissimilarity in ethnicity on one\u27s perceived service quality and purchase intentions. The results provide implications for hospitality managers

Smokers’ reports on receiving a doctor’s advice to quit smoking; receiving the advice is more prevalent among smokers with Crohn’s Disease relative to smokers with Ulcerative Colitis

Receiving a doctor’s advice to quit smoking is an important predictor for improving smokers’ intentions to quit smoking and successful smoking cessation. We examined reports of smokers with Crohn’s Disease (CD) and Ulcerative Colitis (UC) regarding receiving a doctor’s advice to quit smoking in the past 12 months, and eval-uated the differences in the rates of receiving the advice between the CD and UC patients. The data were retrospectively reported by CD and UC patients (n = 453) who self-identified as current smokers in online assessments conducted by IBD Partners in the period from 2011 to 2014 in the USA. Statistical methods included chi-square tests and a multiple logistic regression model for the logit of the probability of receiving the advice as a function of patient’s characteristics and assessment year. Overall, about 77% of smokers reported receiving a doctor’s advice to quit smoking. The percentage was significantly (p \u3c 0.001) higher among smokers with CD (80%) than it was among smokers with UC (63%). While the specificdifferences by CD/UC depended on smoking initiation age, the overall effect of disease type on the odds of receiving the advice remained significant: the odds of receiving the advice were higher for smokers with CD relative to smokers with UC (OR = 3.6, p \u3c 0.001). Although the majority of CD and UC patients report receiving a doctor’s advice to quit smoking, the encountered difference associated with the disease type is concerning. Because long-term smoking increases cancer and mortality risks, doctors should address smoking cessation with all patients who smoke

Inhibition of interleukin-1 signaling enhances elimination of tyrosine kinase inhibitor treated CML stem cells

Treatment of chronic myelogenous leukemia (CML) with BCR-ABL tyrosine kinase inhibitors (TKI) fails to eliminate leukemia stem cells (LSC). Patients remain at risk for relapse, and additional approaches to deplete CML LSC are needed to enhance the possibility of discontinuing TKI treatment. We have previously reported that expression of the pivotal proinflammatory cytokine interleukin-1 (IL-1) is increased in CML bone marrow (BM). We show here that CML LSC demonstrated increased expression of the IL-1 receptors, IL-1RAP and IL- 1R1, and enhanced sensitivity to IL-1-induced NF-KB signaling compared to normal stem cells. Treatment with recombinant IL-1 receptor antagonist (IL-1RA) inhibited IL-1 signaling in CML LSC and inhibited growth of CML LSC. Importantly, the combination of IL-1RA with TKI resulted in significantly greater inhibition of CML LSC compared with TKI alone. Our studies also suggest that IL-1 signaling contributes to overexpression of inflammatory mediators in CML LSC, suggesting that blocking IL-1 signaling could modulate the inflammatory milieu. We conclude that IL-1 signaling contributes to maintenance of CML LSC following TKI treatment, and that IL- 1 blockade with IL-1RA enhances elimination of TKI-treated CML LSC. These results provide a strong rationale for further exploration of anti-IL-1 strategies to enhance LSC elimination in CML

Impact of Maternal Physical Activity and Infant Feeding Practices on Infant Weight Gain and Adiposity

Increasing evidence supports the contribution of intrauterine environmental exposures on obesity risk in offspring. Few studies have included maternal and infant lifestyle factors. Our objective was to study the impact of maternal physical activity, infant feeding, and screen time on offspring weight gain and adiposity. In a prospective cohort study, 246 mothers underwent testing during pregnancy to assess glucose tolerance status and insulin sensitivity. Anthropometry and questionnaires on physical activity, infant feeding, and screen time were completed. Multiple-linear regression was performed to examine the impact of maternal and infant factors on infant weight gain and weight-for-length z-score at 1 year. Infant weight outcomes were negatively predicted by maternal pregravid vigorous/sport index and exclusive breastfeeding duration. After adjustment, each unit increase in maternal pregravid vigorous/sport index decreased infant weight gain by 218.6 g (t=2.44, P=0.016) and weight-for-length z-score by 0.20 (t=2.17, P=0.031). Each month of exclusive breastfeeding reduced infant weight gain by 116.4 g (t=3.97, P<0.001) and weight-for-length z-score by 0.08 (t=2.59, P=0.01). Maternal pregravid physical activity and exclusive breastfeeding duration are associated with weight gain and adiposity as early as 1 year of age

Patients educating health care providers on Lynch syndrome

Objective: Lynch syndrome (LS) patients are at an elevated risk for early-onset cancers, including endometrial and colorectal (CRC). Prior research has shown a deficit in provider knowledge of LS, which may affect patient satisfaction and adherence to recommended screening and surveillance regimens. Studies suggest patients with LS may educate providers perceived as lacking LS knowledge; however, little is known about these interactions. The goal of this study is to assess patient-reported outcomes from clinical interactions where LS patients educate their providers. Methods: Participants (n=55) were asked to complete an in-depth telephone interview. Results: Out of 55 participants, approximately two-thirds (n=37) reported engaging in educational interactions. Participants reported feeling satisfied with the provider response in over half of the reported educational interactions (n=24). Participants reported changes in their patient-provider relationship ranging from improvements in their relationship to termination of services. Conclusion: Patients with LS report educating providers on their diagnosis as well as their screening and surveillance requirements. Patient-reported outcomes of these educational interactions vary based on the provider’s response to the interaction. Providers should be open and receptive to these educational interactions and follow-up on the discussion to improve patient satisfaction

Prostate Cancer Incidence Rates in Africa

African American men have among the highest prostate cancer incidence rates in the world yet rates among their African counterparts are unclear. In this paper, we compared reported rates among black men of Sub-Saharan African descent using data from the International Agency for Research on Cancer (IARC) and the National Cancer Institute Surveillance, Epidemiology, and End Results Program for 1973–2007. Although population-based data in Africa are quite limited, the available data from IARC showed that rates among blacks were highest in the East (10.7–38.1 per 100,000 man-years, age-adjusted world standard) and lowest in the West (4.7–19.8). These rates were considerably lower than those of 80.0–195.3 observed among African Americans. Rates in Africa increased over time (1987–2002) and have been comparable to those for distant stage in African Americans. These patterns are likely due to differences between African and African American men in medical care access, screening, registry quality, genetic diversity, and Westernization. Incidence rates in Africa will likely continue to rise with improving economies and increasing Westernization, warranting the need for more high-quality population-based registration to monitor cancer incidence in Africa

Synapse-Associated Expression of an Acetylcholine Receptor-Inducing Protein, ARIA/Heregulin, and Its Putative Receptors, ErbB2 and ErbB3, in Developing Mammalian Muscle

AbstractDeveloping motor axons induce synaptic specializations in muscle fibers, including preferential transcription of acetylcholine receptor (AChR) subunit genes by subsynaptic nuclei. One candidate nerve-derived signaling molecule is AChR-inducing activity (ARIA)/heregulin, a ligand of the erbB family of receptor tyrosine kinases. Here, we asked whether ARIA and erbB kinases are expressed in patterns compatible with their proposed signaling roles. In developing muscle, ARIA was present not only at synaptic sites, but also in extrasynaptic regions of the muscle fiber. ARIA was synthesized, rather than merely taken up, by muscle cells, as indicated by the presence of ARIA mRNA in muscle and of ARIA protein in a clonal muscle cell line. ARIA-responsive myotubes expressed both erbB2 and erbB3, but little EGFR/erbB1 or erbB4. In adults, erbB2 and erbB3 were localized to the postsynaptic membrane. ErbB3 was restricted to the postsynaptic membrane perinatally, at a time when ARIA was still broadly distributed. Thus, our data are consistent with a model in which ARIA interacts with erbB kinases on the muscle cell surface to provide a local signal that induces synaptic expression of AChR genes. However, much of the ARIA is produced by muscle, not nerve, and the spatially restricted response may result from the localization of erbB kinases as well as of ARIA. Finally, we show that erbB3 is not concentrated at synaptic sites in mutant mice that lack rapsyn, a cytoskeletal protein required for AChR clustering, suggesting that pathways for synaptic AChR expression and clustering interact
