    BACKGROUND: Topical calcipotriol plus 5-fluorouracil (5-FU) combination is an effective immunotherapy against actinic keratosis (AK), which is a precursor to squamous cell carcinoma (SCC). However, the long-term effectiveness of calcipotriol plus 5-FU treatment for SCC prevention is unknown. METHODS: We performed a blinded prospective cohort study on participants of a randomized double-blind clinical trial in which a 4-day course of topical calcipotriol plus 5-FU combination was compared to Vaseline plus 5-FU (control) for AK treatment. SCC and basal cell carcinoma (BCC) incidences were assessed at 1, 2, and 3 years after trial. Tissues were analyzed for calcipotriol plus 5-FU-induced T cell immunity in the skin. RESULTS: Calcipotriol plus 5-FU-induced tissue-resident memory T (Trm) cell formation in face and scalp skin associated with significantly higher erythema scores compared with control (P \u3c 0.01). Importantly, more participants in the test cohort remained SCC-free over the more than 1,500-day follow-up period (P = 0.0765), and significantly fewer developed SCC on the treated face and scalp within 3 years (2 of 30 [7%] versus 11 of 40 [28%] in control group, hazard ratio 0.215 [95% CI: 0.048-0.972], P = 0.032). Accordingly, significantly more epidermal Trm cells persisted in the calcipotriol plus 5-FU-treated face and scalp skin compared with control (P = 0.0028). There was no significant difference in BCC incidence between the treatment groups. CONCLUSION: A short course of calcipotriol plus 5-FU treatment on the face and scalp is associated with induction of robust T cell immunity and Trm formation against AKs and significantly lowers the risk of SCC development within 3 years of treatment.

    Background Adolescents and young adults (AYAs) with cancer are at high risk of poor psychosocial outcomes, and evidence-based interventions designed to meet their psychosocial and communication needs are lacking. The main objective of this project is to test the efficacy of a new adaptation of the Promoting Resilience in Stress Management intervention for AYAs with Advanced Cancer (PRISM-AC). Methods/design The PRISM-AC trial is a 2-arm, parallel, non-blinded, multisite, randomized controlled trial. 144 participants with advanced cancer will be enrolled and randomized to either usual, non-directive, supportive care without PRISM-AC (“control” arm) or with PRISM-AC (“experimental” arm). PRISM is a manualized, skills-based training program comprised of four 30–60 min, one-on-one sessions targeting AYA-endorsed resilience resources (stress-management, goal-setting, cognitive-reframing, and meaning-making). It also includes a facilitated family meeting and a fully equipped smartphone app. The current adaptation includes an embedded advance care planning module. English- or Spanish-speaking individuals 12–24 years old with advanced cancer (defined as progressive, recurrent, or refractory disease, or any diagnosis associated with \u3c 50% survival) receiving care at 4 academic medical centers are eligible. Patients’ caregivers are also eligible to participate in this study if they are able to speak and read English or Spanish, and are cognitively and physically able to participate. Participants in all groups complete surveys querying patient-reported outcomes at the time of enrollment and 3-, 6-, 9-, and 12-months post-enrollment. The primary outcome of interest is patient-reported health-related quality of life (HRQOL) and secondary outcomes of interest include patient anxiety, depression, resilience, hope and symptom burden, parent/caregiver anxiety, depression and health-related quality of life, and family palliative care activation. We will conduct intention-to-treat analysis to compare the group means of primary and secondary outcomes between PRISM-AC arm and control arm with regression models. Discussion This study will provide methodologically rigorous data and evidence regarding a novel intervention to promote resilience and reduce distress among AYAs with advanced cancer. This research has the potential to offer a practical, skills-based curriculum designed to improve outcomes for this high-risk group.

    CONTEXT: Little is known about how parents of children with advanced cancer classify news they receive about their child\u27s medical condition. OBJECTIVE: To develop concepts of "good news" and "bad news" in discussions of advanced childhood cancer from parent perspectives. METHODS: Parents of children with advanced cancer cared for at three children\u27s hospitals were asked to share details of conversations in the preceding 3 months that contained "good news" or "bad news" related to their child\u27s medical condition. We used mixed methods to evaluate parent responses to both open-ended and fixed response items. RESULTS: Of 104 enrolled parents, 86 (83%) completed the survey. Six (7%) parents reported discussing neither good nor bad news, 18 (21%) reported only bad news, 15 (17%) reported only good news, and 46 (54%) reported both good and bad news (1 missing response). Seventy-six parents (88%) answered free response items. Descriptions of both good and bad news discussions consisted predominantly of "tumor talk" or cancer control. Additional treatment options featured prominently, particularly in discussions of bad news (42%). Child well-being, an important good news theme, encompassed treatment tolerance, symptom reduction, and quality of life. CONCLUSION: A majority of parents of children with advanced cancer report discussing both good and bad news in the preceding 3 months. While news related primarily to cancer control, parents also describe good news discussions related to their child\u27s well-being. Understanding how parents of children with advanced cancer classify and describe the news they receive may enhance efforts to promote family-centered communication

    The Outbreak of West Nile Virus Infection in the New York City Area in 1999

    Background In late August 1999, an unusual cluster of cases of meningoencephalitis associated with muscle weakness was reported to the New York City Department of Health. The initial epidemiologic and environmental investigations suggested an arboviral cause. Methods Active surveillance was implemented to identify patients hospitalized with viral encephalitis and meningitis. Cerebrospinal fluid, serum, and tissue specimens from patients with suspected cases underwent serologic and viral testing for evidence of arboviral infection. Results Outbreak surveillance identified 59 patients who were hospitalized with West Nile virus infection in the New York City area during August and September of 1999. The median age of these patients was 71 years (range, 5 to 90). The overall attack rate of clinical West Nile virus infection was at least 6.5 cases per million population, and it increased sharply with age. Most of the patients (63 percent) had clinical signs of encephalitis; seven patients died (12 percent). Muscle weakness was documented in 27 percent of the patients and flaccid paralysis in 10 percent; in all of the latter, nerve conduction studies indicated an axonal polyneuropathy. An age of 75 years or older was an independent risk factor for death (relative risk adjusted for the presence or absence of diabetes mellitus, 8.5; 95 percent confidence interval, 1.2 to 59.1), as was the presence of diabetes mellitus (ageadjusted relative risk, 5.1; 95 percent confidence interval, 1.5 to 17.3). Conclusions This outbreak of West Nile meningoencephalitis in the New York City metropolitan area represents the first time this virus has been detected in the Western Hemisphere. Given the subsequent rapid spread of the virus, physicians along the eastern seaboard of the United States should consider West Nile virus infection in the differential diagnosis of encephalitis and viral meningitis during the summer months, especially in older patients and in those with muscle weakness

    Bacterial microevolution and the Pangenome

    The comparison of multiple genome sequences sampled from a bacterial population reveals considerable diversity in both the core and the accessory parts of the pangenome. This diversity can be analysed in terms of microevolutionary events that took place since the genomes shared a common ancestor, especially deletion, duplication, and recombination. We review the basic modelling ingredients used implicitly or explicitly when performing such a pangenome analysis. In particular, we describe a basic neutral phylogenetic framework of bacterial pangenome microevolution, which is not incompatible with evaluating the role of natural selection. We survey the different ways in which pangenome data is summarised in order to be included in microevolutionary models, as well as the main methodological approaches that have been proposed to reconstruct pangenome microevolutionary history

    Conducting Psychosocial Intervention Research among Adolescents and Young Adults with Cancer: Lessons from the PRISM Randomized Clinical Trial

    No full text
    Background: Adolescents and young adults (AYAs) with cancer have poor psychosocial outcomes, in part because their limited participation in clinical trials precludes intervention-testing. We previously reported results of a successful randomized trial testing an AYA-targeted psychosocial intervention. Here, we aimed to describe strategies learned during the trial’s conduct. Methods: We summarized data from the medical record and staff field notes regarding reasons for participation/non-participation. We conducted two focus groups with study staff; directed content analyses identified strategies for success. Results: 92 AYAs enrolled (77% of approached; n = 50 Usual Care (control), n = 49 PRISM (intervention)). In eligible families who declined participation (n = 22 AYAs, n = 8 parents), the AYAs more commonly had advanced cancer (n = 11 (37%) declined vs. n = 25 (26%) enrolled). AYA reasons for non-enrollment were predominantly “not interested”; parents worried participation was “too burdensome.” Staff strategies for accrual included having significant time to introduce the study and underscoring a desire to learn from the patient. After enrollment, AYAs who discontinued participation were more commonly assigned to control (n = 5 (10%) control vs. n = 2 (4%) intervention). Only n = 1 AYA chose to discontinue participation after receiving the intervention. Conclusions: Efforts to engage AYAs prior to and during studies may help with accrual and retention

    Thesis (Master's)--University of Washington, 2012Purpose: Psychological distress (PD) in a parent may have an effect on their children and other members of their family. We sought to describe the prevalence and predictors of PD among parents of children with advanced cancer. Patients and Methods: Parents of children with progressive, recurrent, or refractory cancer who were treated at one of 3 large children¡&hibar;s hospitals and enrolled in the Pediatric Quality of Life and Evaluation of Symptoms Technology (PediQUEST) study completed the Survey of Caring for Children with Cancer (SCCC). Parent PD was measured by the Kessler-6 general psychological distress scale. K6 scores of >= 7 suggest high distress and those >= 13 indicate serious psychological distress (SPD, U.S. SPD prevalence is 3%). Linear and logistic regression models were used to evaluate associations between PD and child/ parent factors. Results: 86 of 104 enrolled parents completed SCCC (83% participation); 81 had complete K6 data. Over 50% of parents reported high distress and 16% met criteria for SPD. Parent and child demographic factors were not associated with parent PD in this study; however, parent perceptions of prognosis, goals of therapy, perceived child symptoms/suffering, as well as financial hardship were. In multivariate analyses, parent PD scores were higher among those whose care goals were incongruent with their prognostic understanding, whose child was suffering highly, and who perceived great economic hardship due to their child¡&hibar;s illness. Conclusions: Parenting a child with progressive cancer can profoundly affect mental health. Interventions aimed at aligning care goals with prognostic understanding, easing child suffering and financial hardship may improve parental emotional wellbeing
