RESUMEN

OBJECTIVE: Entrustable professional activities (EPAs) have seen widespread adoption in medical education and other health professions education. EPAs aim to provide a bridge between competency-based education and clinical practice by translating competencies into fundamental profession-specific tasks associated with clinical practice. Despite the extensive use of EPAs in health professions education, EPAs have yet to be introduced into chiropractic education. The purpose of this paper is to describe the development and introduction of EPAs as part of 2 community-based chiropractic student preceptorship education programs in the United States. METHODS: EPAs were developed and introduced at 2 community-based chiropractic preceptorship sites in 5 distinct steps: (1) differentiating EPAs from competencies, learning objectives, and knowledge, skills, and attitudes; (2) identifying EPAs; (3) mapping EPAs to competencies and necessary experience, knowledge, and skills; (4) designing EPA assessment strategies; and (5) implementing the use of EPAs. RESULTS: A total of 13 individual EPAs were developed and mapped to Council on Chiropractic Education meta-competency outcomes and underlying experience, knowledge, and skills. Three assessment tools were created to evaluate student entrustability for EPAs and enhance student self-assessment. The EPAs and assessment tools were integrated into chiropractic student preceptorships at each site. CONCLUSION: This paper describes the development and introduction of EPAs at 2 community-based chiropractic preceptorship sites. Future research is needed to develop and standardize EPA use and assessment, and to evaluate outcomes associated with EPA use.

RESUMEN

Millions of tons of acetyl derivatives such as acetic acid and acetic anhydride are produced each year. These building blocks of chemical industry are elaborated into esters, amides, and eventually polymer materials, pharmaceuticals, and other consumer products. Most acetyls are produced industrially using homogeneous precious metal catalysts, principally rhodium and iridium complexes. We report here that abundant nickel can be paired with imidazole-derived carbenes or the corresponding salts to catalyze methyl ester carbonylation with turnover frequency (TOF) exceeding 150 hour-1 and turnover number (TON) exceeding 1600, benchmarks that invite comparisons to state-of-the-art rhodium-based systems and considerably surpass known triphenylphosphine-based nickel catalysts, which operate with TOF ~7 hour-1 and TON ~100 under the same conditions.

RESUMEN

Second autologous hematopoietic cell transplantation (AHCT2) is a useful therapeutic modality for fit patients with multiple myeloma who have durable remission after upfront AHCT. Retrospective studies have suggested a significant benefit of incorporating maintenance therapy post-AHCT2, but prospective data on specific regimens are lacking. The purpose of this study was to investigate the use of elotuzumab, pomalidomide, and dexamethasone (EPd) as salvage therapy prior to and maintenance after AHCT2 for relapsed multiple myeloma. This prospective single-arm phase II trial investigating the use of EPd in combination with AHCT2 in patients with relapsed multiple myeloma was conducted at 2 academic centers in North America. The primary outcome was 1-year progression-free survival (PFS). Twenty-five patients were enrolled on the study. Sixteen patients received EPd induction; six patients (38%) progressed during salvage therapy and were removed from the trial prior to AHCT2. Following a planned safety analysis, the protocol was amended, and EPd induction was removed from the study schema. An additional 9 patients underwent induction off-study and were enrolled on trial for AHCT2 and EPd maintenance. A total of 18 patients underwent AHCT2 and received EPd maintenance. Two patients discontinued treatment because of toxicity, one attributed to elotuzumab and the other to pomalidomide. The 1-year PFS was 72%, and the median PFS was 19 months. The study was closed early owing to poor accrual; 6 patients remained on therapy at time of analysis. EPd maintenance after AHCT2 was safe and tolerable. The 1-year PFS and median PFS were similar to values in previous retrospective reports of outcomes following AHCT2. Further studies are needed to define the optimal use of and protocol for AHCT2 in fit patients with relapsed multiple myeloma.

RESUMEN

Objective: Fragments of fibrillin-1 and fibrillin-2 will be detectable in the plasma of patients with aortic dissections and aneurysms. We sought to determine whether the plasma fibrillin fragment levels (PFFLs) differ between patients with thoracic aortic pathology and those presenting with nonaortic chest pain. Methods: PFFLs were measured in patients with thoracic aortic aneurysm (n = 27) or dissection (n = 28). For comparison, patients without aortic pathology who had presented to the emergency department with acute chest pain (n = 281) were categorized into three groups according to the cause of the chest pain: ischemic cardiac chest pain; nonischemic cardiac chest pain; and noncardiac chest pain. The PFFLs were measured using a sandwich enzyme-linked immunosorbent assay. Results: Fibrillin-1 fragments were detectable in all patients and were lowest in the ischemic cardiac chest pain group. Age, sex, and the presence of hypertension were associated with differences in fibrillin-1 fragment levels. Fibrillin-2 fragments were detected more often in the thoracic aneurysm and dissection groups than in the emergency department chest pain group (P < .0001). Patients with aortic dissection demonstrated a trend toward increased detectability (P = .051) and concentrations (P = .06) of fibrillin-2 fragments compared with patients with aortic aneurysms. Analysis of specific antibody pairs identified fibrillin-1 B15-HRP26 and fibrillin-2 B205-HRP143 as the most informative in distinguishing between the emergency department and aortic pathology groups. Conclusions: Patients with thoracic aortic dissections demonstrated elevated plasma fibrillin-2 fragment levels (B205-HRP143) compared with patients presenting with ischemic or nonischemic cardiac chest pain and increased fibrillin-1 levels (B15-HRP26) compared with patients with ischemic cardiac chest pain. Investigation of fibrillin-1 and fibrillin-2 fragment generation might lead to diagnostic, therapeutic, and prognostic advances for patients with thoracic aortic dissection.

RESUMEN

OBJECTIVE: Cervical spine surgeries for degenerative conditions are rapidly increasing. Cervical post-surgery syndrome consisting of chronic pain, adjacent segment disease, recurrent disc herniation, facet joint pain, and/or epidural scarring is common. Repeat surgery is regularly recommended, though patients are often unable to undergo or decline further surgery. Manual therapy is included in clinical practice guidelines for neck pain and related disorders, however clinical guidance for utilization of manual therapy in adults with prior cervical spine surgery is lacking. This study aimed to synthesize available literature and characterize outcomes and adverse events for manual therapy interventions in adults with prior cervical spine surgery due to degenerative conditions. METHODS: Preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews was followed. PubMed, Cumulative Index of Nursing and Allied Health Literature, physiotherapy evidence database, and Index to Chiropractic Literature were searched from inception through October 2021. English-language literature comprised of randomized clinical trials (RCT), case-control, cohort, and case report designs were included. Adults undergoing manual therapy, with or without combination of other interventions, with prior cervical spine surgery due to degenerative conditions were included. RESULTS: Twelve articles were identified, including 10 case reports, 1 low-quality RCT, and 1 acceptable-quality RCT. Eight case reports described 9 patients with history of fusion surgery. Two case reports described 2 patients with history of discectomy. One case report described one patient with separate operations of a discectomy at one level and a fusion at another level. One case report described 2 patients with history of cervical disc replacement surgery. The two RCTs included 63 and 86 participants, respectively. Use of manual joint mobilization/manipulation, table/instrument assisted mobilization/manipulation, and multimodal interventions were described in eligible studies. Favorable clinical outcomes were reported in 10 studies. Six case reports/series involving 8 patients described use of unclassified forms of manual therapy. Eight studies described the use of multimodal interventions along with manual therapy. One study described high patient satisfaction. Two studies, accounting for 3 patients, reported serious adverse events. CONCLUSIONS: There is a lack of literature informing evidence related to clinical outcomes, patient satisfaction, and adverse events associated with manual therapy for patients with prior cervical spine surgery due to degenerative conditions. High-quality studies of higher-level hierarchical study design are needed to understand the clinical utility and safety profile of manual therapy for this population.

RESUMEN

Aim To quantify and update the years of life lost (YLL), years lived with disability (YLD) and disability-adjusted life years (DALY) due to the adverse effects of medical treatment (AEMT) between 1990 and 2017. Subject and methods We analyzed the latest dataset from the Global Burden of Disease (GBD) 2017 study. We described the burden of AEMT based on the number of DALY. We additionally evaluated the global age and sex-specific DALY and compared the age-standardized rates of DALY across the World Health Organization (WHO) regions from 1990 to 2017. Results Worldwide, the total DALYs due to AEMT were 84.93 [95% uncertainty interval (UI), 62.52 to 102.21] in 1990 and 62.79 (52.09 to 75.45) in 2017 per 100,000 population. The global percentage of change in DALY showed a negative trend of -26.06 % (-41.52 to -10.59) across all WHO regions between 1990 and 2017. The YLD has increased during the period from 1997 to 2017 by 29.47% (17.87 to 41.06). In 2017, men were affected more than women with a DALY of 66.78 in comparison to 58.91 DALY in women. DALY rates per 100,000 were highest across all the WHO regions in the first years of life. The predicted DALY rates were 59.92 (57.52 to 62.32) in the year 2020, 50.36 (32.03 to 68.70) in 2030, and 40.8 (-1.33 to 82.93) in 2040. Conclusion Using the GBD 2017 study data, we found a decrease in the DALY rate due to AEMT between 1990 and 2017 with a varying range of DALY between different WHO regions. DALY also differed by age and sex. The forecasting analyses showed a decrease in DALY due to AEMTs with a significant drop in the European region when compared to the African and American regions. However, the increasing trend for YLD signifies an increasing burden of people living with poor health due to AEMT. Our study proposes to identify disability due to AEMT as a significant public health crisis and calls for policymakers to create a robust revised policy.

RESUMEN

There is an increasing awareness, interest and acceptance of the biopsychosocial (BPS) model by all health care professionals involved with patient care. The areas of spine care and pain medicine are no exception, and in fact, these areas of health care are a major centerpiece of the movement from the traditional biomedical model to a BPS model of patient assessment and delivery of care. The chiropractic approach to health care has a history that is grounded in key aspects of the BPS model. The profession has inherently implemented certain features of the BPS model throughout its history, perhaps without a full understanding or realization. The purpose of this paper is to present an overview of the BPS model, its relationship with spine care and pain management, and to discuss the BPS model, particularly psychosocial aspects, in the context of its historical relationship with chiropractic. We will also provide recommendations for the chiropractic profession as it relates to successful adoption of a full integration of the BPS model.

RESUMEN

OBJECTIVES: This study was a multicenter evaluation of the SAVI SCOUT(®) breast localization and surgical guidance system using micro-impulse radar technology for the removal of nonpalpable breast lesions. The study was designed to validate the results of a recent 50-patient pilot study in a larger multi-institution trial. The primary endpoints were the rates of successful reflector placement, localization, and removal. METHODS: This multicenter, prospective trial enrolled patients scheduled to have excisional biopsy or breast-conserving surgery of a nonpalpable breast lesion. From March to November 2015, 154 patients were consented and evaluated by 20 radiologists and 16 surgeons at 11 participating centers. Patients had SCOUT(®) reflectors placed up to 7 days before surgery, and placement was confirmed by mammography or ultrasonography. Implanted reflectors were detected by the SCOUT(®) handpiece and console. Presence of the reflector in the excised surgical specimen was confirmed radiographically, and specimens were sent for routine pathology. RESULTS: SCOUT(®) reflectors were successfully placed in 153 of 154 patients. In one case, the reflector was placed at a distance from the target that required a wire to be placed. All 154 lesions and reflectors were successfully removed during surgery. For 101 patients with a preoperative diagnosis of cancer, 86 (85.1 %) had clear margins, and 17 (16.8 %) patients required margin reexcision. CONCLUSIONS: SCOUT(®) provides a reliable and effective alternative method for the localization and surgical excision of nonpalpable breast lesions using no wires or radioactive materials, with excellent patient, radiologist, and surgeon acceptance.

RESUMEN

BACKGROUND: The current technique for locating nonpalpable breast lesions is wire localization (WL). Radioactive seed localization and intraoperative ultrasound were developed to improve difficulties with WL. The SAVI SCOUT surgical guidance system was developed to improve these methods. The SCOUT system is a non-radioactive, FDA-cleared medical device that uses electromagnetic wave technology to provide real-time guidance during excisional breast procedures. METHODS: Consenting patients underwent localization and excision using an implantable electromagnetic wave reflective device (reflector) and a detector handpiece with a console. Using image guidance, the reflector was placed up to 7 days before the surgical procedure. The primary end points of the study were successful reflector placement, localization, and retrieval. The secondary end points were percentage of clear margins, reexcision rates, days of placement before excision, and physician comparison with WL. RESULTS: This study analyzed 50 patients. The reflectors were placed under mammographic guidance (n = 18, 36 %) or ultrasound guidance (n = 32, 64 %). Of the 50 patients, 10 (20 %) underwent excisional biopsy and 40 (80 %) had a lumpectomy. The lesion and reflector were successfully removed in all 50 patients, and no adverse events occurred. Of the 41 patients who had in situ and/or invasive carcinoma identified, 38 (93 %) had clear margins and 3 (7 %) were recommended for reexcision. CONCLUSIONS: These data suggest that the SCOUT system is safe and effective for guiding the excision of nonpalpable breast lesions and a viable alternative to standard localization options. A larger prospective, multi-institution trial of SCOUT currently is underway to validate these findings.

RESUMEN

Zebrafish have become a popular organism for the study of vertebrate gene function. The virtually transparent embryos of this species, and the ability to accelerate genetic studies by gene knockdown or overexpression, have led to the widespread use of zebrafish in the detailed investigation of vertebrate gene function and increasingly, the study of human genetic disease. However, for effective modelling of human genetic disease it is important to understand the extent to which zebrafish genes and gene structures are related to orthologous human genes. To examine this, we generated a high-quality sequence assembly of the zebrafish genome, made up of an overlapping set of completely sequenced large-insert clones that were ordered and oriented using a high-resolution high-density meiotic map. Detailed automatic and manual annotation provides evidence of more than 26,000 protein-coding genes, the largest gene set of any vertebrate so far sequenced. Comparison to the human reference genome shows that approximately 70% of human genes have at least one obvious zebrafish orthologue. In addition, the high quality of this genome assembly provides a clearer understanding of key genomic features such as a unique repeat content, a scarcity of pseudogenes, an enrichment of zebrafish-specific genes on chromosome 4 and chromosomal regions that influence sex determination.

RESUMEN

As the wave of the baby boomers shifts the age demographic of patients, the current surgical management of breast cancer in elderly women (≥70 years of age) becomes relevant because deviation from standard treatment often occurs in this group. The purpose of this study was to determine the operative mortality when treated with standard surgical procedures and to investigate trends in the surgical management of breast cancer in the elderly. A total of 5,235 patients undergoing either mastectomy or breast conservation surgery (BCS) for invasive and ductal carcinoma in situ (DCIS) were identified in a retrospective review of a prospectively accrued data base between the years of 1994 and 2007 at the Moffitt Cancer Center. Of the 5,235 patients, 1,028 (20%) patients were ≥70 years of age. The 30-day and 90-day mortality in the elderly group (age ≥70 years) was 0.2% (95% CI 0.02-0.7%) and 0.7% (95% CI 0.3-1.4%), respectively. The 30-day and 90-day mortality among patients <70 years was 0 and 0.05% (2 of 4,207 patients) (95% CI 0.005-0.2), respectively. BCS rates for invasive carcinomas were the highest for patients between 40 and 70 years of age, whereas the mastectomy rates were higher among patients <40 years of age (53%). Elderly women were as likely as women <40 years to have BCS for invasive carcinoma (OR 1.1, 95% CI 0.8-1.5), but more likely to have BCS for DCIS (OR 1.9, 95% CI 1.1-3.3). Surgical mortality in elderly women treated for breast cancer was extremely low and was related to the extent of surgery performed. Breast cancer treatment differed by age groups.

RESUMEN

Concussion is a growing public health issue in the United States, and chronic traumatic encephalopathy (CTE) is the chief long-term concern linked to repeated concussions. Recently, attention has shifted toward subconcussive blows and the role they may play in the development of CTE. We recruited a cohort of high school football players for two seasons of observation. Acceleration sensors were placed in the helmets, and all contact activity was monitored. Pre-season computer-based neuropsychological tests and functional magnetic resonance imaging (fMRI) tests were also obtained in order to assess cognitive and neurophysiological health. In-season follow-up scans were then obtained both from individuals who had sustained a clinically-diagnosed concussion and those who had not. These changes were then related through stepwise regression to history of blows recorded throughout the football season up to the date of the scan. In addition to those subjects who had sustained a concussion, a substantial portion of our cohort who did not sustain concussions showed significant neurophysiological changes. Stepwise regression indicated significant relationships between the number of blows sustained by a subject and the ensuing neurophysiological change. Our findings reinforce the hypothesis that the effects of repetitive blows to the head are cumulative and that repeated exposure to subconcussive blows is connected to pathologically altered neurophysiology.

RESUMEN

Interdigitated electrode (IDE) arrays with nanometer-scale gaps have been utilized to enhance the sensitivity of affinity-based detection. The geometry of nanogap IDEs was first optimized on the basis of simulations of the electric field and current density. It was determined that the gap (G) between the electrodes was the most important geometric parameter in determining the distribution and strength of the electric field and the current density compared to the width (W) and height (H) of the IDEs. Several devices were materialized and analyzed for their sensitivity to the electrochemical environment using faradic electrochemical impedance spectroscopy (EIS) as the detection technique. Nanogap optimized IDEs were then employed as biosensors for the label-free, affinity-based detection of antitissue transglutaminase antibodies (αtTG-Abs), a biomarker for the detection of autoimmune disorder celiac sprue, triggered by ingesting gluten. The label-free biosensor assay was found to be less sensitive compared to on-chip ELISA. Gold nanoparticles (GNPs) were then employed to improve the sensitivity of the nanogap IDE-based biosensor. With GNPs, the transducer sensitivity increased by 350% over that of label-free detection. The suitability of nanogap IDEs as biosensor transducers for EIS in label-free and GNP-labeled formats was established. The immunobiosensor assay detection sensitivity with the GNPs was found comparable to ELISA.

RESUMEN

PURPOSE: We present surgical modifications that improved the outcome of cutaneous ureterostomies. MATERIALS AND METHODS: A total of 310 patients with a median age of 71 years (range 38 to 88) underwent cutaneous ureterostomy as urinary diversion. Median followup was 25 months (range 1 to 172). The technique included 1) transposition of the left ureter above the inferior mesenteric artery, 2) mobilization of the ileocecal segment with repositioning above each terminal ureter, 3) abdominal wall hiatus fixation with 4 angle sutures and 4) YV plasty of the ureters with edge-to-edge anastomosis for stomal creation. In the 161 group 1 patients (59.1%) the Double-J® stents were removed in less than 3 months. Stents remained longer than 3 months in the 111 group 2 patients (40.8%). RESULTS: Of the 272 patients ureteral obstruction developed in 36 (13.2%). Ureteral obstruction was on the right side in 6 patients (2.2%), on the left side in 27 (9.9%) and bilateral in 3 (1.1%). Ureteral obstruction was treated with restenting in 20 cases (55.4%), stomal revision in 12 (33.3%) and conversion to a conduit in 4 (11%). Ureteral obstruction developed on the right side, on the left side and bilaterally in 3.7%, 13.7% and 1.82% of the patients in group 1, and in 0%, 4.5% and 0%, respectively, of those in group 2. Stenting time impacted only the left ureter with less obstruction in the group with longer stent placement (greater than 3 months) (p = 0.01). CONCLUSIONS: As with other types of urinary diversion, left ureteral obstruction is a common complication of bilateral cutaneous ureterostomies. Long-term stenting for greater than 3 months and the applied surgical modifications improved the clinical outcome of this type of urinary diversion.

RESUMEN

For a number of years the BioMart data warehousing system has proven to be a valuable resource for scientists seeking a fast and versatile means of accessing the growing volume of genomic data provided by the Ensembl project. The launch of the Ensembl Genomes project in 2009 complemented the Ensembl project by utilizing the same visualization, interactive and programming tools to provide users with a means for accessing genome data from a further five domains: protists, bacteria, metazoa, plants and fungi. The Ensembl and Ensembl Genomes BioMarts provide a point of access to the high-quality gene annotation, variation data, functional and regulatory annotation and evolutionary relationships from genomes spanning the taxonomic space. This article aims to give a comprehensive overview of the Ensembl and Ensembl Genomes BioMarts as well as some useful examples and a description of current data content and future objectives.

RESUMEN

BACKGROUND: Prior ipsilateral completion axillary lymph node dissection (CALND) may be considered a contraindication to performing a sentinel lymph node (SLN) mapping in a patient with recurrent breast carcinoma. However, reoperative SLN biopsy following axillary dissection would determine if alternative lymphatic drainage pathways exist. If nodes were found to contain metastatic disease, staging and locoregional control of the disease could be affected. MATERIALS AND METHODS: An institutional breast cancer database and electronic health record (IRB No. 102554) prospectively accrued 6225 patients between 1994 and 2007. Under separate IRB approval (IRB No. 102552), this database was queried for patients with a prior history of CALND who received a SLN biopsy. Patients' demographic, clinical, and treatment variables were recorded. RESULTS: Of the 6225 patients, 45 (0.7%) were identified as having previously undergone breast-conservation surgery, CALND, and ipsilateral reoperative SLN mapping and biopsy. Of the 45 patients, 13 (29%) had a successful ipsilateral reoperative SLN mapping and biopsy. Nonaxillary drainage was identified in 5 patients with reoperative SLN biopsy. CONCLUSION: Reoperative SLN mapping and biopsy is feasible in the setting of local recurrence after previous CALND. This procedure performed for breast cancer recurrence provides important staging information while identifying extra-axillary drainage that could affect both staging and local control.

RESUMEN

Previous plastic surgery procedures such as breast augmentation or reduction mammoplasty can potentially alter the lymphatic drainage of the breast. The purpose of this study is to determine the success rates of sentinel node lymphatic mapping in patients with previous plastic surgical procedures of the breast. A total of 83 patients with a history of plastic surgery of the breast that underwent subsequent sentinel node mapping between 1996 and 2008 were retrospectively analyzed. Eight-three patients that underwent a total of 108 sentinel node biopsies. Hundred cases (93%) previously underwent breast augmentation and eight cases (7%) previously underwent reduction mammoplasty. The mean time between the previous plastic surgical procedures and the sentinel node biopsy was 10.3 years (range: 2 months-32 years). Indications for the mapping procedure were invasive cancer (n = 64), ductal carcinoma in situ (n = 17), and prophylactic mastectomy (n = 27). The identification rate of the sentinel node was 95.3% (103/108). The success rate based on type of procedure was 96% (96/100) for augmentation and 87.5% (7/8) for reduction mammoplasty. With a mean follow-up of 3.4 years, there has been only one local axillary recurrence that occurred at the time of an ipsilateral breast recurrence following lumpectomy. Lymphatic mapping can be successfully performed in patients who have previously undergone plastic surgery operations.

RESUMEN

Education programs at all levels must be able to demonstrate successful program outcomes. Grades alone do not represent a comprehensive measurement methodology for assessing student learning outcomes at either the course or program level. The development and application of assessment rubrics provides an unequivocal measurement methodology to ensure a quality learning experience by providing a foundation for improvement based on qualitative and quantitatively measurable, aggregate course and program outcomes. Learning outcomes are the embodiment of the total learning experience and should incorporate assessment of both qualitative and quantitative program outcomes. The assessment of qualitative measures represents a challenge for educators in any level of a learning program. Nursing provides a unique challenge and opportunity as it is the application of science through the art of caring. Quantification of desired student learning outcomes may be enhanced through the development of assessment rubrics designed to measure quantitative and qualitative aspects of the nursing education and learning process. They provide a mechanism for uniform assessment by nursing faculty of concepts and constructs that are otherwise difficult to describe and measure. A protocol is presented and applied to a doctoral nursing education program with recommendations for application and transformation of the assessment rubric to other education programs. Through application of these specially designed rubrics, all aspects of an education program can be adequately assessed to provide information for program assessment that facilitates the closure of the gap between desired and actual student learning outcomes for any desired educational competency.
