What attributes should a specialist in rehabilitation have? Seven suggested specialist capabilities in practice

Problem: Many services and professionals refer to themselves as providing rehabilitation. There is no agreed method for determining whether someone has specific expertise in rehabilitation. This makes it difficult for patients and payers to know whether professionals who claim to provide rehabilitation are specifically expert in rehabilitation. Context: Doctors have a medical speciality of rehabilitation. The medical training curriculum gives attributes that differentiate a rehabilitation specialist from other doctors. Until recently, these attributes were competencies to undertake activities associated with specialization. Apart from nurses, who have at least one, unofficial, curriculum identifying specific competencies, other professions involved in rehabilitation do not have any way to show specialization in rehabilitation. Capabilities in Practice: The U.K. General Medical Council accredits specialist medical training. It has moved from specifying multiple practical clinical competencies to specifying fewer high-level ‘Capabilities in Practice’. Six are generic to all doctors, eight identify the trained doctor as having specialist rehabilitation skills. This article adopts this approach to put forward seven generic and seven specialist capabilities to identify any professional as having special expertise in rehabilitation. The seven specialist capabilities centre on the biopsychosocial model of illness and multidisciplinary teamwork. Four of them could be used to define a specialist rehabilitation team. Conclusion: Seven capabilities identifying specialization in rehabilitation are put forward for discussion. They could form the basis of a formal recognition that any professional has additional expertise in rehabilitation. A validating authority would be needed to provide oversight and governance

Making healthcare decisions in a person’s best interests when they lack capacity: Clinical guidance based on a review of evidence

Objective: To clarify the concept of best interests, setting out how they should be ascertained and used to make healthcare decisions for patients who lack the mental capacity to make decisions. Context: The legal framework is the Mental Capacity Act (MCA) 2005, which applies to England and Wales. Theory: Unless there is a valid and applicable Advance Decision, an appointed decision-maker needs to decide for those without capacity. This may be someone appointed by the patient through a Lasting Power of Attorney, or a Deputy appointed by the court. Otherwise the decision-maker is usually the responsible clinician. Different approaches exist to surrogate decision-making cross-nationally. In England and Wales, decision-making is governed by the MCA 2005, which uses a person-centred, flexible best interests (substituted interests) approach. Observations: The MCA is often not followed in healthcare settings, despite widespread mandatory training. The possible reasons include its focus on single decisions, when multiple decisions are made daily, the potential time involved and lack of clarity about who is the responsible decision-maker. Solution: One solution is to decide a strategic policy to cover more significant (usually health-related) decisions and to separate these from day-to-day relational decisions covering care and activities. Once persistent lack of capacity is confirmed, an early meeting should be arranged with family and friends, to start a process of sharing information about the patient’s medical condition and their values, wishes, feelings and beliefs with a view to making timely treatment decisions in the patient’s best interests

Rehabilitation after COVID-19: An evidence-based approach

After severe COVID-19 disease, many patients will experience a variety of problems with normal functioning and will require rehabilitation services to overcome these problems. The principles of and evidence on rehabilitation will allow an effective response. These include a simple screening process; use of a multidisciplinary expert team; four evidence-based classes of intervention (exercise, practice, psychosocial support, and education particularly about self-management); and a range of tailored interventions for other problems. The large number of COVID-19 patients needing rehabilitation coupled with the backlog remaining from the crisis will challenge existing services. The principles underpinning vital service reconfigurations needed are discussed

Silyl trifluoromethanesulfonate-activated para-methoxybenzyl methyl ether as an alkylating agent for thiols and aryl ketones

para-Methoxybenzyl methyl ether acts as an alkylating agent for thiols in the presence of trimethylsilyl trifluoromethanesulfonate and trialkylamine base in good yields (58-96%). Aryl ketones are alkylated under similar conditions, probably through an enol silane intermediate, also in high yields (67-95%). The active alkylating species is likely a p-methoxybenzyl cation

The effects of small-needle-knife therapy on pain and mobility from knee osteoarthritis: A pilot randomized controlled study

Objective: To investigate the effect of small needle-knife therapy in people with painful knee osteoarthritis. Design Pilot randomised, controlled trial. Setting. Rehabilitation hospital. Subjects. In-patients with osteo-arthritis of the knee. Interventions: Either 1-3 small needle-knife treatments over 7 days or oral Celecoxib. All patients stayed in hospital three weeks, receiving the same mobility-focused rehabilitation. Measures. Oxford Knee Score (OKS), gait speed and kinematics were recorded at baseline, at 3 weeks (discharge) and at three-months (OKS only). Withdrawal from the study, and adverse events associated with the small needle knife therapy were recorded. Results: 83 patients were randomized: 44 into the control group, of whom 10 were lost by 3 weeks and 12 at 3 months; 39 into the experimental group of whom 8 were lost at 3 weeks and 3 months. The mean (SE) OKS scores at baseline were Control 35.86 ( 1.05), Exp 38.38 ( 0.99); at three weeks 26.64 (0.97) and 21.94 (1.23); and at three months 25.83 (0.91) and 20.48 (1.14) The mean (SE) gait speed at baseline was 1.07 (0.03) m/sec (Control) and 0.98 (0,03), and at three weeks was 1.14 (0.03) and 1.12 (0.03) (p < 0.05). Linear mixed model statistical analysis showed that the improvements in the experimental group were statistically significant for total OKS score at discharge and three months. Conclusions: Small needle-knife therapy added to standard therapy for patients with knee osteoarthritis, was acceptable, safe, and reduced pain and improved global function on the Oxford Knee Score. Further research is warranted

Gravitational Waves From Known Pulsars: Results From The Initial Detector Era

We present the results of searches for gravitational waves from a large selection of pulsars using data from the most recent science runs (S6, VSR2 and VSR4) of the initial generation of interferometric gravitational wave detectors LIGO (Laser Interferometric Gravitational-wave Observatory) and Virgo. We do not see evidence for gravitational wave emission from any of the targeted sources but produce upper limits on the emission amplitude. We highlight the results from seven young pulsars with large spin-down luminosities. We reach within a factor of five of the canonical spin-down limit for all seven of these, whilst for the Crab and Vela pulsars we further surpass their spin-down limits. We present new or updated limits for 172 other pulsars (including both young and millisecond pulsars). Now that the detectors are undergoing major upgrades, and, for completeness, we bring together all of the most up-to-date results from all pulsars searched for during the operations of the first-generation LIGO, Virgo and GEO600 detectors. This gives a total of 195 pulsars including the most recent results described in this paper.United States National Science FoundationScience and Technology Facilities Council of the United KingdomMax-Planck-SocietyState of Niedersachsen/GermanyAustralian Research CouncilInternational Science Linkages program of the Commonwealth of AustraliaCouncil of Scientific and Industrial Research of IndiaIstituto Nazionale di Fisica Nucleare of ItalySpanish Ministerio de Economia y CompetitividadConselleria d'Economia Hisenda i Innovacio of the Govern de les Illes BalearsNetherlands Organisation for Scientific ResearchPolish Ministry of Science and Higher EducationFOCUS Programme of Foundation for Polish ScienceRoyal SocietyScottish Funding CouncilScottish Universities Physics AllianceNational Aeronautics and Space AdministrationOTKA of HungaryLyon Institute of Origins (LIO)National Research Foundation of KoreaIndustry CanadaProvince of Ontario through the Ministry of Economic Development and InnovationNational Science and Engineering Research Council CanadaCarnegie TrustLeverhulme TrustDavid and Lucile Packard FoundationResearch CorporationAlfred P.

Multiple novel prostate cancer susceptibility signals identified by fine-mapping of known risk loci among Europeans

Genome-wide association studies (GWAS) have identified numerous common prostate cancer (PrCa) susceptibility loci. We have fine-mapped 64 GWAS regions known at the conclusion of the iCOGS study using large-scale genotyping and imputation in 25 723 PrCa cases and 26 274 controls of European ancestry. We detected evidence for multiple independent signals at 16 regions, 12 of which contained additional newly identified significant associations. A single signal comprising a spectrum of correlated variation was observed at 39 regions; 35 of which are now described by a novel more significantly associated lead SNP, while the originally reported variant remained as the lead SNP only in 4 regions. We also confirmed two association signals in Europeans that had been previously reported only in East-Asian GWAS. Based on statistical evidence and linkage disequilibrium (LD) structure, we have curated and narrowed down the list of the most likely candidate causal variants for each region. Functional annotation using data from ENCODE filtered for PrCa cell lines and eQTL analysis demonstrated significant enrichment for overlap with bio-features within this set. By incorporating the novel risk variants identified here alongside the refined data for existing association signals, we estimate that these loci now explain ∼38.9% of the familial relative risk of PrCa, an 8.9% improvement over the previously reported GWAS tag SNPs. This suggests that a significant fraction of the heritability of PrCa may have been hidden during the discovery phase of GWAS, in particular due to the presence of multiple independent signals within the same regio

Dissecting the Shared Genetic Architecture of Suicide Attempt, Psychiatric Disorders, and Known Risk Factors

Background Suicide is a leading cause of death worldwide, and nonfatal suicide attempts, which occur far more frequently, are a major source of disability and social and economic burden. Both have substantial genetic etiology, which is partially shared and partially distinct from that of related psychiatric disorders. Methods We conducted a genome-wide association study (GWAS) of 29,782 suicide attempt (SA) cases and 519,961 controls in the International Suicide Genetics Consortium (ISGC). The GWAS of SA was conditioned on psychiatric disorders using GWAS summary statistics via multitrait-based conditional and joint analysis, to remove genetic effects on SA mediated by psychiatric disorders. We investigated the shared and divergent genetic architectures of SA, psychiatric disorders, and other known risk factors. Results Two loci reached genome-wide significance for SA: the major histocompatibility complex and an intergenic locus on chromosome 7, the latter of which remained associated with SA after conditioning on psychiatric disorders and replicated in an independent cohort from the Million Veteran Program. This locus has been implicated in risk-taking behavior, smoking, and insomnia. SA showed strong genetic correlation with psychiatric disorders, particularly major depression, and also with smoking, pain, risk-taking behavior, sleep disturbances, lower educational attainment, reproductive traits, lower socioeconomic status, and poorer general health. After conditioning on psychiatric disorders, the genetic correlations between SA and psychiatric disorders decreased, whereas those with nonpsychiatric traits remained largely unchanged. Conclusions Our results identify a risk locus that contributes more strongly to SA than other phenotypes and suggest a shared underlying biology between SA and known risk factors that is not mediated by psychiatric disorders.Peer reviewe

Genomic Relationships, Novel Loci, and Pleiotropic Mechanisms across Eight Psychiatric Disorders

Genetic influences on psychiatric disorders transcend diagnostic boundaries, suggesting substantial pleiotropy of contributing loci. However, the nature and mechanisms of these pleiotropic effects remain unclear. We performed analyses of 232,964 cases and 494,162 controls from genome-wide studies of anorexia nervosa, attention-deficit/hyper-activity disorder, autism spectrum disorder, bipolar disorder, major depression, obsessive-compulsive disorder, schizophrenia, and Tourette syndrome. Genetic correlation analyses revealed a meaningful structure within the eight disorders, identifying three groups of inter-related disorders. Meta-analysis across these eight disorders detected 109 loci associated with at least two psychiatric disorders, including 23 loci with pleiotropic effects on four or more disorders and 11 loci with antagonistic effects on multiple disorders. The pleiotropic loci are located within genes that show heightened expression in the brain throughout the lifespan, beginning prenatally in the second trimester, and play prominent roles in neurodevelopmental processes. These findings have important implications for psychiatric nosology, drug development, and risk prediction.Peer reviewe
