Distinct karyotypic and mutational landscape in trisomy AML.

Trisomy karyotype occurs in 5%-10% of AML. Its mutational landscape and prognostic significance are not well defined. A cohort of 156 trisomy AML patients was analysed, with reference to 615 cytogenetically normal (CN) AML patients. Trisomy AML showed distinct mutational landscape with more prevalent SMC1A, N/KRAS, ASXL1 and BCOR but fewer CEBPAbZIP and NPM1 mutations in patients ≤60, and fewer NPM1 mutations in those >60. NRAS mutations were associated with poor outcome in trisomy AML, whereas DNMT3A and FLT3-ITD mutations had neutral effect. Trisomy AML appeared biologically distinct from CN-AML.

Worldwide Survey of Clinician Practice on use of Adjunctive Therapies Following Botulinum Toxin Injection for Spasticity.

OBJECTIVE: Non-pharmacological adjunctive therapies can be used alongside botulinum toxin injection to enhance its efficacy. The objective of this global study was to determine the current practice and perception among clinicians of the use of adjunctive therapies after botulinum toxin injections for the treatment of limb spasticity. METHODS: A questionnaire with 22 questions on clinical practice demographics, self-reported use and clinician opinion on barriers to the use of complementary therapies, and priorities for future research was translated into 7 languages and distributed worldwide through national and international professional associations concerning (neuro)rehabilitation. RESULTS: A total of 527 clinicians from 52 countries responded to the survey. Most commonly used physical interventions were: active exercise programmes at home (81%), stretching programmes at home (81%), and splinting (70%), followed by active movement exercises (65%) and within 30 min of botulinum toxin injection and constraint induced movement therapy (63%). The main barriers reported by clinicians to provision of these interventions were clinicians' lack of time, limited financial resources, and lack of evidence. Future research should focus primarily on immediate active movement exercises and passive stretching. CONCLUSION: Worldwide, clinicians often recommend adjunctive therapies after a botulinum toxin injection to reduce spasticity. The most commonly used physical interventions among clinicians were active exercises at home, stretching at home, and splinting. Lack of evidence, time and financial constraints were identified as barriers to providing these interventions.

Practice Patterns of Physicians Using Adjunct Therapies with Botulinum Toxin Injection for Spasticity: A Canadian Multicenter Cross-Sectional Survey.

BACKGROUND: Adjunct therapies are nonpharmacological treatments used with botulinum toxin (BoNT) injection that may improve spasticity outcomes. It has been suggested that physicians consider adjunct therapies as a part of comprehensive spasticity management. It is unclear which adjunct therapies are used by physicians in clinical practice. OBJECTIVE: To determine physician practice patterns and perceptions of use of adjunct therapies following BoNT injection for limb spasticity. DESIGN: Cross-sectional national survey of current clinical practice using a 22-item questionnaire developed by the authors. SETTING: Not applicable. PARTICIPANTS: Survey respondents were physicians actively administering BoNT injections for limb spasticity management across Canada (N = 48). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Types of adjunct therapies used by physicians; physician opinions on barriers to adjunct therapy use, patient preferences, and future research priorities. RESULTS: Most physicians prescribe home stretching programs, home active exercise programs, and splinting; however, many physicians perceive that these same adjunct therapies are unwanted by patients. A minority of physicians prescribe electrical stimulation (ES), transcutaneous electrical nerve stimulation (TENS), casting, and extracorporeal shockwave therapy; financial limitations and perceived lack of evidence were identified as barriers to their use. Significantly more physicians practicing in academic settings compared with nonacademic, community, and private practice settings used functional ES (59% vs 11%) and TENS (41% vs 0%) as adjunct therapies (P < .05). Research priorities included determining the effectiveness of immediate postinjection application of adjunct therapies (eg, injected muscle activation with ES or stretching) and nutraceuticals. CONCLUSIONS: Canadian physicians frequently use adjunct therapies in combination with BoNT injection to treat spasticity. Financial and time constraints are identified as barriers to implementation of adjunct therapies that are currently supported by research, and patient preferences may also affect compliance. Future research should focus on adjunct therapies that overcome these barriers.

Updates in the Treatment of Post-Stroke Pain.

PURPOSE OF REVIEW: To provide an overview of the current treatment strategies for common subtypes of post-stroke pain. RECENT FINDINGS: There is growing research interest in non-pharmacological treatment approaches for chronic pain, including neurostimulation as well as lifestyle and psychosocial interventions. Newer pharmacotherapy research includes cannabinoids and NMDA-receptor antagonists as well as bee venom. Persistent post-stroke headache is an increasingly appreciated entity, though the role of novel chronic migraine treatments for post-stroke headache is not known. Overall, most treatment approaches to post-stroke pain lack high-quality evidence. Stroke survivors are in need of effective treatments based on methodologically sound evidence. To address the interplay of clinical and psychosocial factors that contribute to post-stroke pain, it may be reasonable to adopt a multimodal treatment strategy incorporating both lifestyle interventions and conventional therapies.
