Chronic Illness, Treatment Choice and Workforce Participation

Choices with respect to labor force participation and medical treatment are increasingly intertwined. Technological advances present patients with new choices and may facilitate continued employment for the growing number of chronically ill individuals. We examine joint work/treatment decisions of end stage renal disease patients, a group for whom these tradeoffs are particularly salient. Using a simultaneous equations probit model, we find that treatment choice is a significant predictor of employment status. However, the effect size is considerably smaller than in models that do not consider the joint nature of these choices.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45858/1/10754_2004_Article_5145693.pd

Protocol for a Randomized Multiple Center Trial of Conservative Versus Liberal Oxygenation Targets in Critically Ill Children (Oxy-PICU): Oxygen in Paediatric Intensive Care

OBJECTIVES: Oxygen administration is a fundamental part of pediatric critical care, with supplemental oxygen offered to nearly every acutely unwell child. However, optimal targets for systemic oxygenation are unknown. Oxy-PICU aims to evaluate the clinical effectiveness and cost-effectiveness of a conservative peripheral oxygen saturation (Spo2) target of 88-92% compared with a liberal target of more than 94%. DESIGN: Pragmatic, open, multiple-center, parallel group randomized control trial with integrated economic evaluation. SETTING: Fifteen PICUs across England, Wales, and Scotland. PATIENTS: Infants and children age more than 38 week-corrected gestational age to 16 years who are accepted to a participating PICU as an unplanned admission and receiving invasive mechanical ventilation with supplemental oxygen for abnormal gas exchange. INTERVENTION: Adjustment of ventilation and inspired oxygen settings to achieve an Spo2 target of 88-92% during invasive mechanical ventilation. MEASUREMENTS AND MAIN RESULTS: Randomization is 1:1 to a liberal Spo2 target of more than 94% or a conservative Spo2 target of 88-92% (inclusive), using minimization with a random component. Minimization will be performed on: age, site, primary reason for admission, and severity of abnormality of gas exchange. Due to the emergency nature of the treatment, approaching patients for written informed consent will be deferred to after randomization. The primary clinical outcome is a composite of death and days of organ support at 30 days. Baseline demographics and clinical status will be recorded as well as daily measures of oxygenation and organ support, and discharge outcomes. This trial received Health Research Authority approval on December 23, 2019 (reference: 272768), including a favorable ethical opinion from the East of England-Cambridge South Research Ethics Committee (reference number: 19/EE/0362). Trial findings will be disseminated in national and international conferences and peer-reviewed journals

The diverse oncogenic and tumour suppressor roles of p63 and p73 in cancer: a review by cancer site

p63 and p73, the two other members of the p53 family, were identified almost 15 years ago. Here, we review their potential use for diagnosis, prognosis and prediction of response to therapy in various cancers. The two genes show distinct expression patterns in both normal and cancer tissues and each gene gives rise to multiple protein isoforms with different activities, including those with tumour-suppressor or oncogenic effects. Despite such complexity, some common themes emerge; p63 is commonly overexpressed as the ΔNp63 isoform and sometimes associated with TP63 amplification, whereas p73 is often reduced (by methylation or gene loss), or there is an increase in the ratio of ΔNp73 to TAp73. These generalisations do not apply universally; TAp63 is overexpressed in haematological malignancies, TP63 mis-sense mutations have been reported in squamous cancers and TP63 translocations occur in lymphomas and some lung adenocarcinomas. There are associations with disease prognosis and response to specific therapies in individual cancer types for both p63 and p73, making their analysis of clinical relevance. We also discuss their utility for aiding in differential diagnosis, which has been demonstrated for p63, but not yet for p73. Throughout, we highlight the discrepant nature of many studies due to the variable methodologies employed, the lack of systematic evaluation of isoforms and the problems of poor antibody characterization and crossreactions within the p63/p73 family. Finally, we emphasize the value of recently developed isoformspecific reagents that have clear advantages for the study of p63 and p73 experimentally and clinically

Prospective observational study to evaluate the performance of the BioSure HIV Self-Test in the hands of lay users

OBJECTIVES: In order to assess whether the BioSure HIV Self-Test could be reliably performed by users at home and to determine whether they were able to perform and correctly interpret the test, we carried out an evaluation study among attendees at a sexual health service. METHODS: A prospective observational study of clinic attendees to determine their ability to follow the instructions, complete the test on themselves and correctly interpret the results. The evaluation included interpretation of three dummy (contrived) devices, chosen at random from a sample of 12 devices, to ensure that a sufficient number of all possible test outcomes were included. RESULTS: Two hundred participants were recruited. 97.0% (95% CI 93.5 to 98.9) conducted the test so as to achieve a valid result. 99.5% correctly identified the test result. Participants correctly interpreted the result of 94.0% (95% CI 91.4 to 95.9) of 586 contrived devices. CONCLUSIONS: The majority of participants were able to follow the instructions and perform the test in order to get a valid result. Interpretation of the test results was good and the majority of participants were able to correctly read the result of their own and contrived tests. The availability of HIV self-tests will provide another option to increase access to testing particularly for those who may not wish or are unable to access clinical services
