The importance of cancer patients' functional recollections to explore the acceptability of an isometric-resistance exercise intervention: A qualitative study
Background and Aims: Although it has been widely recognized the potential of physical activity to help cancer patients' preparation for and recovery from surgery, there is little consideration of patient reflections and recovery experiences to help shape adherence to exercise programs. The aim was to explore the acceptability of our newly proposed isometric exercise program in a large general hospital trust in England providing specialist cancer care by using patient recollections of illness and therapy prior to undertaking a randomized controlled trial. Methods: Four Focus groups (FGs) were conducted with cancer survivors with an explicit focus on patient identity, functional capacity, physical strength, exercise advice, types of activities as well as the timing of our exercise program and its suitability. Thematic framework analysis was used with NVivo 11. Results: FG data was collected in January 2016. A total of 13 patients were participated, 10 were male and 3 were female with participants' ages ranging from 39 to 77. Data saturation was achieved when no new information had been generated reaching āinformation redundancy.ā Participants reflected upon their post-surgery recovery experiences on the appropriateness and suitability of the proposed intervention, what they thought about its delivery and format, and with hindsight what the psychological enablers and barriers would be to participation. Conclusion: Based upon the subjective recollections and recovery experiences of cancer survivors, isometric-resistance exercise interventions tailored to individuals with abdominal cancer has the potential to be acceptable for perioperative patients to help increase their physical activity and can also help with emotional and psychological recovery
Muscle strengthening intervention for boys with haemophilia: Developing and evaluating a best-practice exercise programme with boys, families and health-care professionals
Background: Muscle strengthening exercises have the potential to improve outcomes for boys with haemophilia, but it is unclear what types of exercise might be of benefit.
We elicited the views of health-care professionals, boys and their families to create and assess a home-based muscle strengthening programme.
Objective: To design and develop a muscle strengthening programme with healthcare professionals aimed at improving musculoskeletal health, and refine the intervention by engaging boys with haemophilia and their families (Study 1). Following delivery, qualitatively evaluate the feasibility and acceptability of the exercise programme with the boys and the study's physiotherapists (Study 2). Design: A person-based approach was used for planning and designing the exercise programme, and evaluating it post-delivery. The following methods were utilized: modified nominal group technique (NGT) with health-care professionals; focus group with families; exit interviews with boys; and interviews with the study's physiotherapists.
Results: Themes identified to design and develop the intervention included exercises to lower limb and foot, dosage, age accommodating, location, supervision and
monitoring and incentivization. Programme refinements were carried out following engagement with the boys and families who commented on: dosage, location, supervision
and incentivization. Following delivery, the boys and physiotherapists commented on progression and adaptation, physiotherapist contact, goal-setting, creating
routines and identifying suitable timeframes, and a repeated theme of incentivization.
Conclusions: An exercise intervention was designed and refined through engagement with boys and their families. Boys and physiotherapists involved in the intervention's delivery were consulted who found the exercises to be generally acceptable with some minor refinements necessary
Longitude : a privacy-preserving location sharing protocol for mobile applications
Location sharing services are becoming increasingly popular. Although many location sharing services allow users to set up privacy policies to control who can access their location, the use made by service providers remains a source of concern. Ideally, location sharing providers and middleware should not be able to access usersā location data without their consent. In this paper, we propose a new location sharing protocol called Longitude that eases privacy concerns by making it possible to share a userās location data blindly and allowing the user to control who can access her location, when and to what degree of precision. The underlying cryptographic algorithms are designed for GPS-enabled mobile phones. We describe and evaluate our implementation for the Nexus One Android mobile phone

Acceptability and feasibility of an isometric resistance exercise program for abdominal cancer surgery: An embedded qualitative study
Although it is recognized in the early stages of cancer recovery that changes in lifestyle including increases in physical activity improves physical function, there are no clear findings whether low versus moderate intensity activity or home or gym exercise offer optimal benefit. Isometric-resistance exercises can be carried out with very little equipment and space and can be performed while patients are bed-bound in hospital or at home. This embedded qualitative study, based in an English hospital trust providing specialist cancer care, was undertaken as a component of a feasibility trial to evaluate the acceptability and feasibility of an isometric-resistance exercise program and explore the suitability of functional assessments by drawing from the experiences of abdominal cancer patients following surgery. Telephone interviews were undertaken with 7 participants in the intervention group, and 8 interviews with the usual care group (nĀ¼ 15). The gender composition consisted of 11 females and 4 males. Participantsā ages ranged from 27 to 84 (MĀ¼ 60.07, SD Ā¼ 15.40). Interviews were conducted between August 2017 and May 2018, with audio files digitally recorded and data coded using thematic framework analysis. Our results show that blinding to intervention or usual care was a challenge, participants felt the intervention was safe and suitable aided by the assistance of a research nurse, yet, found the self-completion questionnaire tools hard to complete. Our study provides an insight of trial processes, participantsā adherence and completion of exercise interventions, and informs the design and conduct of larger RCTs based on the experiences of abdominal cancer surgery patients
Phenotype variability of infantile-onset multisystem neurologic, endocrine, and pancreatic disease IMNEPD
Infantile-onset multisystem neurologic, endocrine, and pancreatic disease
(IMNEPD) has been recently linked to biallelic mutation of the peptidyl-tRNA
hydrolase 2 gene PTRH2. Two index patients with IMNEPD in the original report
had multiple neurological symptoms such as postnatal microcephaly,
intellectual disability, developmental delay, sensorineural deafness,
cerebellar atrophy, ataxia, and peripheral neuropathy. In addition, distal
muscle weakness and abnormalities of thyroid, pancreas, and liver were found.
Here, we report five further IMNEPD patients with a different homozygous PTRH2
mutation, broaden the phenotypic spectrum of the disease and differentiate
common symptoms and interindividual variability in IMNEPD associated with a
unique mutation. We thereby hope to better define IMNEPD and promote
recognition and diagnosis of this novel disease entity

Effects of pre- and post-operative resistance exercise interventions on recovery of physical function in patients undergoing abdominal surgery for cancer: A systematic review of randomised controlled trials
Objective:
To systematically review the effects of pre- and post-operative resistance exercise training on the recovery of physical function in patients undergoing abdominal surgery for cancer.
Data sources:
A systematic review of English articles using Medline, PEDro, Cinahl and The Cochrane Library electronic databases was undertaken.
Eligibility criteria for selecting studies:
Studies were included if they used a randomised, quasi-randomised, or controlled trial study design and compared the effects of a muscle-strengthening exercise intervention (+/- other therapy) with a comparative non-exercise group; involved adult participants (ā„18 years) who had elected to undergo abdominal surgery for cancer; and used muscle strength, physical function, self-reported functional ability, range of motion and/or a performance-based test as an outcome measure.
Results:
Following screening of titles and abstracts of the 588 publications retrieved from the initial search, 24 studies met the inclusion criteria and were accessed for review of the full-text version of the article and 2 eligible met the inclusion criteria and were included in the review. One exercise programme was undertaken pre-operatively and the other post-operatively, until discharge from hospital. There were no differences between groups in either study.
Conclusion:
The only two studies designed to determine whether pre- or post-operative resistance muscle-strengthening exercise programmes improved or negatively affected physical function outcomes in patients undergoing abdominal surgery for cancer provide inconclusive results. The exercise interventions of the included studies were performed for 5 and 8 session respectively
Biallelic UBE4A loss-of-function variants cause intellectual disability and global developmental delay
Purpose: To identify novel genes associated with intellectual disability (ID) in four unrelated families. Methods: Here, through exome sequencing and international collaboration, we report eight individuals from four unrelated families of diverse geographic origin with biallelic loss-of-function variants in UBE4A. Results: Eight evaluated individuals presented with syndromic intellectual disability and global developmental delay. Other clinical features included hypotonia, short stature, seizures, and behavior disorder. Characteristic features were appreciated in some individuals but not all; in some cases, features became more apparent with age. We demonstrated that UBE4A loss-of-function variants reduced RNA expression and protein levels in clinical samples. Mice generated to mimic patient-specific Ube4a loss-of-function variant exhibited muscular and neurological/behavioral abnormalities, some of which are suggestive of the clinical abnormalities seen in the affected individuals. Conclusion: These data indicate that biallelic loss-of-function variants in UBE4A cause a novel intellectual disability syndrome, suggesting that UBE4A enzyme activity is required for normal development and neurological function
Pairwise tests of purchasing power parity
Given nominal exchange rates and price data on N + 1 countries indexed by i = 0,1,2,ā¦, N, the standard procedure for testing purchasing power parity (PPP) is to apply unit root or stationarity tests to N real exchange rates all measured relative to a base country, 0, often taken to be the U.S. Such a procedure is sensitive to the choice of base country, ignores the information in all the other cross-rates and is subject to a high degree of cross-section dependence which has adverse effects on estimation and inference. In this article, we conduct a variety of unit root tests on all possible N(N + 1)/2 real rates between pairs of the N + 1 countries and estimate the proportion of the pairs that are stationary. This proportion can be consistently estimated even in the presence of cross-section dependence. We estimate this proportion using quarterly data on the real exchange rate for 50 countries over the period 1957-2001. The main substantive conclusion is that to reject the null of no adjustment to PPP requires sufficiently large disequilibria to move the real rate out of the band of inaction set by trade costs. In such cases, one can reject the null of no adjustment to PPP up to 90% of the time as compared to around 40% in the whole sample using a linear alternative and almost 60% using a nonlinear alternative
