Symptom burden in patients with chronic kidney disease not requiring renal replacement therapy

Background: Although evidence shows that patients with end stage renal disease (ESRD) experience a high symptom burden which impacts on quality of life (QoL), less is known about patients with earlier stages of chronic kidney disease (CKD). This study aimed to explore symptom burden and potential contributing factors in patients with CKD Stage 1-5 not requiring renal replacement therapy (RRT). Methods: Patients with CKD Stage 1-5 and not on RRT were asked to report their symptoms using the Leicester Uraemic Symptom Score (LUSS), a questionnaire which assesses the frequency and intrusiveness of 11 symptoms commonly reported by kidney patients. Results: Symptoms were assessed in 283 CKD Stage 1-5 patients: 54% male, mean age 60.5 standard error± 1.0, mean eGFR 38ml/min/1.73m2. Some 96% (95% confidence interval 93.2-98.0) of participants reported experiencing at least one symptom, the median reported being six. Excessive tiredness (81%;76.0-85.6), sleep disturbance (70%;64.3-75.3) and pain in bones/joints (69%;63.4-74.6) were reported most commonly. Overall, few significant associations were found between biochemical markers of disease severity and symptom burden. Men tended to report fewer symptoms than women and South Asian patients often described experiencing symptoms with a greater severity. Older patients found musculoskeletal symptoms more intrusive whereas younger patients found reduced concentration more intrusive. Conclusions: Our findings suggest that patients with CKD stages 1-5 experience a multitude of symptoms that could potentially impact QoL. Using multidimensional tools like the LUSS, more exploration and focus could provide a greater opportunity for patient focussed symptom control from the earliest stages of CKD.Peer-reviewedPublisher Versio

The prevalence and incidence of mental ill-health in adults with autism and intellectual disabilities

The prevalence, and incidence, of mental ill-health in adults with intellectual disabilities and autism were compared with the whole population with intellectual disabilities, and with controls, matched individually for age, gender, ability-level, and Down syndrome. Although the adults with autism had a higher point prevalence of problem behaviours compared with the whole adult population with intellectual disabilities, compared with individually matched controls there was no difference in prevalence, or incidence of either problem behaviours or other mental ill-health. Adults with autism who had problem behaviours were less likely to recover over a two-year period than were their matched controls. Apparent differences in rates of mental ill-health are accounted for by factors other than autism, including Down syndrome and ability level

Interview with Bob Tyrer by Brien Williams

Biographical NoteRobert Stanley “Bob” Tyrer was born on April 30, 1957, in Hamilton, Ohio, to James and Margaret Tyrer. He grew up in a suburb of Detroit, Michigan. In 1974 he became interested in the Watergate hearings and went to listen to then Congressman Cohen give a talk in Birmingham, Michigan. In 1975 he began college at George Washington University and volunteered in Cohen’s congressional office. He worked on Cohen’s 1978 Senate campaign and stayed in Maine to manage the Bangor office, completing his last year of college at the University of Maine. He returned to Washington, D.C. as Senator Cohen’s press secretary in 1981. He became chief of staff in 1986 and remained in that position for the rest of Cohen’s tenure in the Senate. He was Susan Collins’s campaign manager for her 1996 Senate campaign. He went with Cohen to the Department of Defense in 1997 as chief of staff. At the time of this interview he was with the Cohen Group. SummaryInterview includes discussion of: first encounter with Cohen; interning in Cohen’s congressional office; working in Maine and for Maine interests without being a Mainer; a story about his confusion about a road called “the airline”; his job as press secretary; transitioning to the chief of staff role; Senator Cohen’s detachment from partisan politics; the division of labor in the Senate office; different management styles of Senators Cohen and Mitchell; partisanship; lessons learned from the 1974 gubernatorial race; Mitchell’s U.S. Senate appointment in 1980; the Iran-Contra affair; working together as the Maine delegation; the similarities between Mitchell and Cohen; the joint approach of the Mitchell and Cohen offices and the staff interaction between their offices; the change when Mitchell became majority leader and how he and Cohen would joke about it; the evolution of the leader’s job and the increased importance of fund-raising; Mitchell and Cohen’s respective decisions to retire; Cohen’s career after the Senate; the similarities and differences in Cohen and Mitchell’s voting records; the behind the scenes role of Senate staff; Cohen’s philosophy of letting the merits dictate his point of view; Mitchell’s legacy; Mitchell’s accomplishment in Ireland; an anecdote about the first time Tyrer and Mitchell met and Mitchell wanting to know how he could get The New York Times delivered early in the morning; Mitchell’s ability to always be the first to get in touch with constituents who were ill or had a death in the family; and Mitchell’s drive and detail-oriented approach

Nightly treatment of primary insomnia with prolonged release melatonin for 6 months: a randomized placebo controlled trial on age and endogenous melatonin as predictors of efficacy and safety

<p>Background: Melatonin is extensively used in the USA in a non-regulated manner for sleep disorders. Prolonged release melatonin (PRM) is licensed in Europe and other countries for the short term treatment of primary insomnia in patients aged 55 years and over. However, a clear definition of the target patient population and well-controlled studies of long-term efficacy and safety are lacking. It is known that melatonin production declines with age. Some young insomnia patients also may have low melatonin levels. The study investigated whether older age or low melatonin excretion is a better predictor of response to PRM, whether the efficacy observed in short-term studies is sustained during continued treatment and the long term safety of such treatment.</p> <p>Methods: Adult outpatients (791, aged 18-80 years) with primary insomnia, were treated with placebo (2 weeks) and then randomized, double-blind to 3 weeks with PRM or placebo nightly. PRM patients continued whereas placebo completers were re-randomized 1:1 to PRM or placebo for 26 weeks with 2 weeks of single-blind placebo run-out. Main outcome measures were sleep latency derived from a sleep diary, Pittsburgh Sleep Quality Index (PSQI), Quality of Life (World Health Organzaton-5) Clinical Global Impression of Improvement (CGI-I) and adverse effects and vital signs recorded at each visit.</p> <p>Results: On the primary efficacy variable, sleep latency, the effects of PRM (3 weeks) in patients with low endogenous melatonin (6-sulphatoxymelatonin [6-SMT] ≤8 μg/night) regardless of age did not differ from the placebo, whereas PRM significantly reduced sleep latency compared to the placebo in elderly patients regardless of melatonin levels (-19.1 versus -1.7 min; P = 0.002). The effects on sleep latency and additional sleep and daytime parameters that improved with PRM were maintained or enhanced over the 6-month period with no signs of tolerance. Most adverse events were mild in severity with no clinically relevant differences between PRM and placebo for any safety outcome.</p> <p>Conclusions: The results demonstrate short- and long-term efficacy and safety of PRM in elderly insomnia patients. Low melatonin production regardless of age is not useful in predicting responses to melatonin therapy in insomnia. The age cut-off for response warrants further investigation.</p&gt

Parent-of-origin-specific allelic associations among 106 genomic loci for age at menarche.

Age at menarche is a marker of timing of puberty in females. It varies widely between individuals, is a heritable trait and is associated with risks for obesity, type 2 diabetes, cardiovascular disease, breast cancer and all-cause mortality. Studies of rare human disorders of puberty and animal models point to a complex hypothalamic-pituitary-hormonal regulation, but the mechanisms that determine pubertal timing and underlie its links to disease risk remain unclear. Here, using genome-wide and custom-genotyping arrays in up to 182,416 women of European descent from 57 studies, we found robust evidence (P < 5 × 10(-8)) for 123 signals at 106 genomic loci associated with age at menarche. Many loci were associated with other pubertal traits in both sexes, and there was substantial overlap with genes implicated in body mass index and various diseases, including rare disorders of puberty. Menarche signals were enriched in imprinted regions, with three loci (DLK1-WDR25, MKRN3-MAGEL2 and KCNK9) demonstrating parent-of-origin-specific associations concordant with known parental expression patterns. Pathway analyses implicated nuclear hormone receptors, particularly retinoic acid and γ-aminobutyric acid-B2 receptor signalling, among novel mechanisms that regulate pubertal timing in humans. Our findings suggest a genetic architecture involving at least hundreds of common variants in the coordinated timing of the pubertal transition
