Mohs micrographic surgery (MMS) for cutaneous melanoma is becoming more prevalent, but surgical technique varies.
To define variations in published techniques for MMS for melanoma.
A systematic ...review was performed of PubMed, EMBASE, and Scopus databases to identify all articles describing surgical techniques for MMS for melanoma. Technical details were recorded for the preoperative, intraoperative, and postoperative phases of MMS.
Twenty-four articles were included. Mohs surgeons vary in how they assess clinical margins, how wide a margin they excise on the first MMS layer, and how they process tissue to determine tumor stage and margin clearance during MMS for melanoma.
Mohs micrographic surgery for melanoma is performed with varied surgical techniques. To establish best practices, additional research is necessary to determine how different techniques affect outcomes.
•Choosing Wisely recommendations could reduce low-value care in physical therapy.•Optimizing language could increase implementation of the recommendations.•Physical therapists were less willing to ...follow negatively framed recommendations.•They were most willing to follow recommendations with high detail.•They were more willing to follow recommendations with alternatives to low-value care.
Choosing Wisely recommendations could reduce physical therapists’ use of low-value care.
To investigate whether language influences physical therapists’ willingness to follow the Australian Physiotherapy Association's (APA) Choosing Wisely recommendations.
Best-worst Scaling survey
The six original APA Choosing Wisely recommendations were modified based on four language characteristics (level of detail, strength- qualified/unqualified, framing, and alternatives to low-value care) to create 60 recommendations. Physical therapists were randomised to a block of seven choice tasks, which included four recommendations. Participants indicated which recommendation they were most and least willing to follow. A multinomial logistic regression model was used to create normalised (0=least preferred; 10=most preferred) and marginal preference scores.
215 physical therapists (48.5% of 443 who started the survey) completed the survey. Participants' mean age (SD) was 38.7 (10.6) and 47.9% were female. Physical therapists were more willing to follow recommendations with more detail (marginal preference score of 1.1) or that provided alternatives to low-value care (1.3) and less willing to follow recommendations with negative framing (−1.3). The use of qualified (‘don't routinely’) language (vs. unqualified - ‘don't’) did not affect willingness. Physical therapists were more willing to follow recommendations to avoid imaging for non-specific low back pain (3.9) and electrotherapy for low back pain (3.8) vs. recommendation to avoid incentive spirometry after upper abdominal and cardiac surgery.
Physical therapists were more willing to follow recommendations that provided more detail, alternatives to low-value care, and were positively framed. These findings can inform the development of future Choosing Wisely recommendations and could help reduce low-value physical therapy.
IntroductionThe REFORM (REhabilitation FOR Musculoskeletal conditions) trial is a non-inferiority randomised controlled trial (n=210) designed to determine whether a supported home exercise programme ...is as good or better than a course of face-to-face physiotherapy for the management of some musculoskeletal conditions. The trial is currently being conducted across Sydney government hospitals in Australia. This process evaluation will run alongside the REFORM trial. It combines qualitative and quantitative data to help explain the trial results and determine the feasibility of rolling out supported home exercise programmes in settings similar to the REFORM trial.Methods and analysisTwo theoretical frameworks underpin our process evaluation methodology: the Realist framework (context, mechanism, outcomes) considers the causal assumptions as to why a supported home exercise programme may be as good or better than face-to-face physiotherapy in terms of the context, mechanisms and outcomes of the trial. The RE-AIM framework describes the Reach, Effectiveness, Adoption, Implementation and Maintenance of the intervention. These two frameworks will be broadly used to guide this process evaluation using a mixed-methods approach. For example, qualitative data will be derived from interviews with patients, healthcare professionals and stakeholders, and quantitative data will be collected to determine the cost and feasibility of providing supported home exercise programmes. These data will be analysed iteratively before the analysis of the trial results and will be triangulated with the results of the primary and secondary outcomes.Ethics and disseminationThis trial will be conducted in accordance with the National Health and Medical Research Council National Statement on Ethical Conduct in Human Research (2018) and the Note for Good Clinical Practice (CPMP/ICH-135/95). Ethical approval was obtained on 17 March 2017 from the Northern Sydney Local Health District Human Research Ethics Committee (trial number: HREC/16HAWKE/431-RESP/16/287) with an amendment for the process evaluation approved on 4 February 2020. The results of the process evaluation will be disseminated through publications in peer-reviewed journals and presentations at scientific conferences.Trial registration numberACTRN12619000065190.
highlights the findings and application of Cochrane reviews and other evidence pertinent to the practice of physical therapy. The Cochrane Library is a respected source of reliable evidence related ...to health care. Cochrane systematic reviews explore the evidence for and against the effectiveness and appropriateness of interventions--medications, surgery, education, nutrition, exercises--and the evidence for and against the use of diagnostic tests for specific conditions. Cochrane reviews are designed to facilitate the decisions of clinicians, patients, and others in health care by providing a careful review and interpretation of research studies published in the scientific literature. (1) Each article in this PTJ series will summarize a Cochrane review or other scientific evidence resource on a single topic and will present clinical scenarios based on real patients to illustrate how the results of the review can be used to directly inform clinical decisions. This article focuses on the effectiveness of exercise for the prevention of recurrence of nonspecific low back pain. Can an exercise program decrease the number of recurrences in individuals such as this patient with recurrent low back pain?
Glioblastoma multiforme (GBM) is the most lethal of brain tumors and is highly resistant to ionizing radiation (IR) and chemotherapy. Here, we report on a molecular mechanism by which a key ...glioma-specific mutation, epidermal growth factor receptor variant III (EGFRvIII), confers radiation resistance. Using Ink4a/Arf-deficient primary mouse astrocytes, primary astrocytes immortalized by p53/Rb suppression, as well as human U87 glioma cells, we show that EGFRvIII expression enhances clonogenic survival following IR. This enhanced radioresistance is due to accelerated repair of DNA double-strand breaks (DSB), the most lethal lesion inflicted by IR. The EGFR inhibitor gefitinib (Iressa) and the phosphatidylinositol 3-kinase (PI3K) inhibitor LY294002 attenuate the rate of DSB repair. Importantly, expression of constitutively active, myristylated Akt-1 accelerates repair, implicating the PI3K/Akt-1 pathway in radioresistance. Most notably, EGFRvIII-expressing U87 glioma cells show elevated activation of a key DSB repair enzyme, DNA-dependent protein kinase catalytic subunit (DNA-PKcs). Enhanced radioresistance is abrogated by the DNA-PKcs-specific inhibitor NU7026, and EGFRvIII fails to confer radioresistance in DNA-PKcs-deficient cells. In vivo, orthotopic U87-EGFRvIII-derived tumors display faster rates of DSB repair following whole-brain radiotherapy compared with U87-derived tumors. Consequently, EGFRvIII-expressing tumors are radioresistant and continue to grow following whole-brain radiotherapy with little effect on overall survival. These in vitro and in vivo data support our hypothesis that EGFRvIII expression promotes DNA-PKcs activation and DSB repair, perhaps as a consequence of hyperactivated PI3K/Akt-1 signaling. Taken together, our results raise the possibility that EGFR and/or DNA-PKcs inhibition concurrent with radiation may be an effective therapeutic strategy for radiosensitizing high-grade gliomas.
Many educational interventions seek to change teachers’ instructional practice. Standards-based observation systems are a common and useful tool to understand these interventions’ impact, but the ...process of measuring instructional change with observation systems is highly complex. This paper introduces a framework for examining and understanding potential instrumentation biases that arise when evaluations use observation systems to understand instructional change. The framework systematizes two processes that all studies must undertake: (1) the process of operationalizing the construct of teaching quality, and (2) the process of data collection. A study that engages in these processes generates observation scores that capture their own raters’ perspectives on specific segments of instruction. These scores must be generalized to draw conclusions about the intended constructs and settings. Systematizing these two processes highlights the necessary steps of a validity argument supporting evaluation conclusions and the instrumentation biases that threaten such conclusions. The framework is illustrated with an example from our recent work, which sought to understand instructional change since the adoption of the Common Core State Standards (CCSS).
Synthetic meshes are increasingly used in the surgical management of stress urinary incontinence and pelvic-organ prolapse in an attempt to improve success rates and increase the longevity of ...repairs. This review describes and analyses complications following pelvic-floor procedures employing synthetic meshes.
Type I monofilament polypropylene mesh with a large pore size is currently the mesh of choice. Chronic inflammation is a typical host response, whereas acute inflammation and predominant CD20+ lymphocyte infiltration represent an adverse host reaction and may result in defective healing. Mesh properties influence the performance and complication rate. Mesh-related complications after midurethral slings and mesh sacrocolpopexies with monofilament polypropylene are rare. An up to 26% mesh erosion rate and up to 38% dyspareunia rate with vaginally introduced mesh for pelvic-organ prolapse repair has been reported. Concurrent hysterectomy seems to increase mesh erosion rates.
Surgeons should be aware of the potential complications of synthetic meshes. Until data on the safety and efficacy of synthetic mesh in vaginal reconstructive surgery emerge, its routine use outside of clinical trials cannot be recommended.
Abstract The number of septic and aseptic total hip arthroplasty (THA) revisions will increase, which involves a greater financial burden. We here provide a retrospective consecutive analysis of the ...major variable direct costs involved in revision THA for aseptic and septic failure. A total of 144 patients (30 septic, 114 aseptic) treated between January 1, 2009 and March 31, 2012 was included. The management of septic THA loosening is much more expensive than that of aseptic loosening ($14,379.8 vs. $5,487.4). This difference is mainly attributable to the two-stage exchange technique used for septic failure (hospital stay: 40.2 vs. 15.6 days) and significantly higher implant costs ($3,930.9 vs. $2,298.2). The septic implantation part is on average $3,384.6 more expensive than aseptic procedures ( P < .001).
