Background/aims: Some of the most promising avenues of cancer clinical investigation center on immunotherapeutic approaches. These approaches have provided notable gains in cancer therapeutics with recent Food and Drug Administration approvals of agents of this class in several types of cancers, although gains for ovarian cancer lag behind. This study examined perceptions of therapeutic trials including immunotherapy and virotherapy among ovarian cancer patients and their family members. Methods: A total of 72 semi-structured qualitative interviews were conducted with 33 patients and 39 family members at two National Cancer Institute–designated comprehensive cancer centers. Eligible patients were diagnosed with epithelial ovarian, primary peritoneal, or fallopian tube carcinoma and had experience with clinical trial conversations; family members were nominated by patients and interviewed separately. Applied thematic analysis was used to understand and interpret the data. Results: More participants were aware of vaccine trials than virus trials, although more than half had heard of at least one of them. Initial reactions to vaccine trials were generally favorable. For many, childhood experience with vaccines lent a familiar frame of reference. Virus trials elicited more negative initial reactions, including the use of adjectives such as “scary” and “dreadful.” Viruses seemed contagious or difficult to control. Increased receptivity to these trials occurred in the context of limited therapeutic options and cancer recurrence. Most participants, including those not immediately drawn to these types of trials, indicated openness to learning more. Conclusion: Although vaccine and viral trials are both immunologically based therapeutic approaches, patients who are offered these trials may perceive their potential benefit and safety quite differently. There is a need to consider terminology, solicit and address “gut reactions,” and provide information that enables patients and their family members to better understand the science behind these trials.

Objective The goal of this study was to identify distinct frailty trajectories (clusters of individuals following a similar progression of frailty over time) in an ageing population and to determine social and behavioural factors associated with frailty trajectories. Design Population-based cohort study. Setting Olmsted County, Minnesota. Participants Olmsted County, Minnesota residents aged 60–89 in 2005. Primary outcome measure Changes in frailty over an 8-year period from 2005 to 2012, measured by constructing a yearly frailty index. Frailty trajectories by decade of age were determined using k-means cluster modelling for longitudinal data. Results After adjustment for age and sex, all social and behavioural factors (education, marital status, living arrangements, smoking status and alcohol use) were significantly associated with frailty trajectories in those aged 60–69 and 70–79 years. After further adjustment for baseline frailty, the likelihood of being in the high frailty trajectory was greatest among those reporting concerns from relatives/friends about alcohol consumption (OR (95% CI) 2.26 (1.19 to 4.29)) and those with less than a high school education (OR (95% CI) 1.98 (1.32 to 2.96)) in the 60–69 year olds. In the 70–79 year olds, the largest associations were observed among those with concerns from oneself about alcohol consumption (OR (95% CI) 1.92 (1.23 to 3.00)), those with less than a high school education (OR (95% CI) 1.57 (1.12 to 2.22)), and those living with family (vs spouse; OR (95% CI) 1.76 (1.05 to 2.94)). No factors remained associated with frailty trajectories in the 80–89 year olds after adjustment for baseline frailty. Conclusions Social and behavioural factors are associated with frailty, with stronger associations observed in younger ages. Recognition of social and behavioural factors associated with increasing frailty may inform interventions for individuals at risk of worsening frailty, specifically when targeted at younger individuals.

AbstractIntroductionDespite advances in trauma care, hemorrhage continues to be the leading cause of preventable mortality in trauma. The evidence to support its use in non‐trauma patients is limited. We aim to report our experience with prehospital blood product transfusion. We hypothesize that it is safe, appropriately utilized, and that our protocol, which was designed for trauma patients, is adaptable to fit the needs of non‐trauma patients.MethodsPatients transfused with blood products, packed red blood cells (pRBCs) or plasma, in the prehospital environment between 2002 and 2014 were included. Trauma patients were compared to non‐trauma patients using descriptive statistics.ResultsA total of 857 patients (n = 549 trauma and n = 308 non‐trauma) were transfused with pRBCs (76 %, n = 654, mean 1.6 ± 1.1 units en route), plasma (53 %, n = 455, mean 1.7 ± 0.7 unit), or both (29 %, n = 252) during ground (12 %) or air (84 %) critical care transport. Mean age was 60.8 ± 21.6 years with 60.1 % (n = 515) males. Subsequently, in‐hospital blood transfusions were performed in 80 % of patients, operations in 44 %, and endoscopy in 31 %. Five percent (n = 41) of patients did not require any of these interventions. Thirty‐day mortality rate was 18 %, and one patient (<0.01 %) had a transfusion reaction. The majority of patients were non‐trauma (n = 549, 64 %). Of the non‐trauma patients, 219 (40 %) were surgical, 193 (35 %) gastrointestinal bleeds, and 137 (25 %) medical.ConclusionBoth non‐trauma and trauma patients require blood products for life threatening hemorrhage and the majority required further interventions. Further research on the benefits of transfusion among non‐trauma patients is warranted.

BACKGROUNDPrior studies have shown that a higher hospital volume or physician caseload is associated with better outcomes for complex and uncommon surgical procedures. Similar studies in the medical management of rare diseases such as hematologic cancers are limited. This retrospective, observational study using the US National Cancer Data Base determined the extent to which the number of new non‐Hodgkin lymphoma (NHL) patients treated annually at a treatment facility affected overall survival (OS).METHODSThere were 278,985 patients treated at 1151 facilities from 1998 to 2006. Treatment facilities were classified by quartiles based on the average number of new NHL patients seen annually: quartile 1 (Q1), 2 to 13 patients; quartile 2 (Q2), 14 to 20 patients; quartile 3 (Q3), 21 to 32 patients; and quartile 4 (Q4), 33 or more patients. The outcome of interest was OS according to facility volume.RESULTSThe unadjusted median OS was 61.8 months for Q1, 65.9 months for Q2, 71.4 months for Q3, and 83.6 months for Q4. A multivariate analysis that was adjusted for demographic (sex, age, race, and ethnicity), socioeconomic (income and insurance type), geographic (area of residence), disease‐specific (NHL subtype and stage), and facility‐specific factors (type and location) showed that the facility volume was associated with OS. Compared with patients at Q4 facilities, patients at lower quartile facilities had higher mortality (hazard ratio for Q3, 1.05 [95% confidence interval, 1.04‐1.06]; hazard ratio for Q2, 1.08 [95% confidence interval, 1.07‐1.10]; hazard ratio for Q1, 1.14 [95% confidence interval, 1.11‐1.17]).CONCLUSIONSNHL patients treated at higher volume facilities may survive longer than those treated at lower volume facilities. Further work is needed to understand the mechanisms of these differences and whether volume should be considered in the determination of referrals for NHL patients.

Twenty volunteers with normal noses were studied to determine the effect of phenylephrine on nasal ciliary function. In vivo study of this drug was performed in 15 patients and revealed a significant increase in their ciliary beat frequency from a control of 11 Hz to 12.03 Hz (p = 0.001). Mucociliary transit times in these volunteers were also studied, revealing a mean of 9.9 minutes prestimulation and 10.2 minutes poststimulation, which was not statistically significant (p = 0.77). Five additional subjects donated ciliated mucosal samples for in vitro analysis of varying concentrations of this agent that showed a significant ciliostimulatory effect at lower concentrations (0.01%), with a progressive cilioinhibitory effect at higher concentrations (0.25%, 0.5%). The 0.05% concentration showed no significant change in ciliary activity compared to control measurements. These data demonstrate that phenylephrine has a ciliostimulatory effect in vivo, as well as in appropriate concentrations in vitro, and should be safe and relatively nontoxic to the mucociliary apparatus for short‐term use.3

AbstractObjectiveDisparities in tobacco use persist despite successful policies reducing use within the United States. In particular, the prevalence of tobacco use in rural and certain minority communities is significantly higher compared to that of their counterparts. In this work, we examine the impact of rurality, mental health, and racial discrimination on tobacco use.MethodsData come from the 2003 California Health Interview Survey (n = 42,044). Modified Poisson regression models were adjusted for age, sex, race/ethnicity, birth origin, education, income, insurance, and marital status.ResultsCompared to urban residents, rural residents had a significantly higher risk for smoking after adjustment (RR = 1.10, 95% CI: 1.01‐1.19). Those who reported having experienced racial discrimination also had a significantly greater risk for smoking compared to those who did not (RR = 1.17, 95% CI: 1.07‐1.27). Additionally, those who reported higher stress had a significantly greater risk for smoking (RR = 1.61, 95% CI: 1.07‐1.67). There was evidence of interaction between rurality and race/ethnicity, and rurality and gender (P < .05).ConclusionResiding in rural areas was associated with an increased risk for smoking, above and beyond sociodemographics. There were no significant differences across rural‐urban environments for the relationship between stress and tobacco use—an indication that the impact of stress and discrimination is not buffered or exacerbated by environmental characteristics potentially found in either location. Mechanisms that explain rural‐urban tobacco use disparities need to be explored, and smoking cessation programs and policies should be tailored to target these factors within rural communities.
