Characterizing Standardized Functional Data at Inpatient Rehabilitation Facilities

ObjectiveThe Improving Medicare Post-Acute Care Transformation Act of 2014 mandates using standardized patient functional data across post-acute settings. This study characterized similarities and differences in clinician-observed scores of self-care and transfer items for the standardized section GG functional domain and the functional independent measure (FIM) at inpatient rehabilitation facilities.DesignWe conducted secondary analyses of 2017 Uniform Data System for Medical Rehabilitation national data. Patients were assessed by clinicians on both section GG and FIM at admission and discharge. We identified 7 self-care items and 6 transfer items in section GG conceptually equivalent with FIM. Clinician-assessed scores for each pair of items were examined using score distributions, Bland-Altman plot, correlation (Pearson coefficients), and agreement (kappa and weighted kappa) analyses.Setting and ParticipantsIn all, 408,491 patients were admitted to Uniform Data System for Medical Rehabilitation-affiliated inpatient rehabilitation facilities with one of the following impairments: stroke, brain dysfunction, neurologic condition, orthopedic disorders, and debility.MeasuresSection GG and FIM.ResultsPatients were scored as more functionally independent in section GG compared with FIM, but change score distributions and score orders within impairment groups were similar. Total scores in section GG had strong positive correlations (self-care: r = 0.87 and 0.95; transfer: r = 0.82 and 0.90 at admission and discharge, respectively) with total FIM scores. Weak to moderate ranking agreements with total FIM scores were observed (self-care: kappa = 0.49 and 0.60; transfers: kappa = 0.43 and 0.52 at admission and discharge, respectively). Lower agreements were observed for less able patients at admission and for higher ability patients of their change scores.Conclusions and ImplicationsOverall, response patterns were similar in section GG and FIM across impairments. However, variations exist in score distributions and ranking agreement. Future research should examine the use of GG codes to maintain effective care, outcomes, and unbiased reimbursement across post-acute settings.     

The association between sport-related concussion and musculoskeletal injury in university rugby athletes

ObjectivesThe study aimed to analyse the association between Sports-Related Concussion (SRC) and Subsequent Musculoskeletal Injury (MSK) in United Kingdom university-aged rugby union players whilst considering the effects of sex, athlete playing position and injury location.DesignRetrospective cohort study. A period of 365 days with 0–90, 91–180 and 181–365 days sub-periods was analysed for the following variables; MSK injury incidence, occurrence, severity, injury location, playing position and sex.SettingInjury data was collected from the Sports Development Centre database at Loughborough University.ParticipantsA total of 408 injuries in 181 athletes (55 females and 126 males) were included.ResultsThe MSK injury incidence of SRC group was significantly higher than control and higher post-SRC than pre-SRC period over a 365-day period (p=0.012 and p=0.034, respectively). The odds ratios of MSK injury incidence between groups and between periods were 1.62 (95% CI, 1.10–2.25) and 1.57 (95% CI ,1.08–2.29). A SRC was not associated with a greater time loss from a subsequent MSK injury or a specific MSK injury location.ConclusionsAthletes with a second recorded injury were more likely to sustain a MSK injury if they had experienced SRC, however, there was no indication a SRC resulted in greater time loss from a MSK injury.     

Evaluation of 5-aminolevulinic acid-mediated photodynamic therapy in postmenopausal women with persistent HPV infection with or without cervical and vaginal low-grade squamous intraepithelial lesions (CIN1/VaIN1)

ObjectiveTo analyze the efficacy and safety of photodynamic therapy (PDT) on postmenopausal women with persistent human papillomavirus (HPV) infection with or without low-grade cervical and vaginal intraepithelial neoplasia (CIN1 and VaIN1).Materials and methodsThe clinicopathological and follow-up data of 86 postmenopausal women with HPV infection (35 cases with chronic cervicitis and 51 cases with CIN1/VaIN1) were collected. All the women in this group met these criteria: menopausal time ≥ 1 year, HPV infection time ≥ 2 years, colposcopy and pathological diagnosis of biopsy ≤ CIN1/VaIN1 before PDT treatment, and 5-aminolaevulinic acid (5-ALA) as photosensitizer treating for 6 times with a week interval. The above patients were followed up 6 months and 12 months after PDT treatment, and the follow-up contents included HPV typing, cytology, colposcopy and pathological examinations. HPV negative conversion rate and lesion remission rate are the evaluation indicators of treatment efficacy. In addition, we also assessed the safety of PDT treatment.ResultsAt 12-month follow-up, the overall HPV clearance rate was 60% (45/75), of which the negative conversion rate of 16/18 HPV was 41.38% (12/29), and non-16/18 HPV was 71.74% (33/46) (p = 0.009). In patients without lesions, the HPV clearance rate was 51.72% (15/29), while in patients with CIN1/VaIN1 (n = 46), the HPV complete remission rate and lesion regression rate were 65.22% (30/46) and 89.13% (41/46), respectively. In addition, the clearance rate of HPV in lesion regression group was significantly higher than that in lesion persistence/progression group (0.00% vs. 73.17%, p = 0.003). The adverse reactions after PDT treatment were mild, mainly manifested as increased vaginal secretions or burning/tingling.ConclusionsPhotodynamic therapy can significantly enhance the elimination rate of persistent HPV infection in postmenopausal women and reduce the progression of CIN1/VaIN1. It could be an effective conservative treatment for persistent HPV infection and CIN1/VaIN1 in postmenopausal women.     

Transhiatal lower mediastinal lymph node dissection for esophagogastric junction carcinoma by interconnecting four body cavities

BackgroundDue to the limited number of landmark structures, it is difficult to standardize the surgical procedures for advanced esophagogastric junction cancer such as Ivor Lewis esophagectomy that require transhiatal lower mediastinal lymph node dissection (TH-LMND). We demonstrate an easily reproducible procedure for TH-LMND, wherein four body cavities, namely, the abdominal cavity, infracardiac bursa (ICB), and left and right thoracic cavities are interconnected.MethodsFirst, the dissection between the right crus and the esophagus was used to connect the abdominal cavity to the ICB — a lower mediastinal cavity separated from the omental bursa during embryonic development [1,2]. Second, the right thoracic cavity was opened with the shortest distance by dissecting the cranial side of the ICB. The right pulmonary ligament was dissected from the right lung. Third, the dissection to the contralateral side while exposing the aorta and the pericardium connected the left and right thoracic cavities. Then, the left pulmonary ligament was dissected from the left lung. The dissected tissues, including the lymph nodes, were subsequently peeled from the esophagus.ResultsBetween April 2018 and August 2021, 14 patients underwent laparoscopic or robotic TH-LMND via the procedure above. The median time required to complete the dissection was 75 min. None of the procedures were converted to open surgery, and none of the patients experienced intraoperative complications such as pericardial injury, lung injury, or massive bleeding.ConclusionThe surgical concept of interconnecting four body cavities made the procedure more accessible and reproducible while achieving en bloc TH-LMND.     

Survival and Outcomes of Newly Diagnosed Multiple Myeloma Patients Stratified by Transplant Status 2007-2018: Retrospective Analysis from the Canadian Myeloma Research Group Database

BackgroundConsiderable progress has been made in therapeutic options for multiple myeloma (MM). Understanding the current landscape of MM treatment options and associated outcomes in the real world is important in providing key insights into clinical and knowledge gaps which could be targeted for further optimization.MethodsThe Canadian Myeloma Research Group Database (CMRG-DB) is a prospectively maintained disease-specific database with >7000 patients. The objective of this study was to describe the trends in the treatment landscape and outcomes including early mortality, time to next treatment, and overall survival (OS) in each line of treatment stratified by autologous stem cell transplant (ASCT) receipt among newly-diagnosed MM patients in Canada between 2007 and 2018.ResultsA total of 5154 patients were identified among which 3030 patients (58.8%) received an upfront ASCT and 2124 (41.2%) did not. At diagnosis, the median age was 64 years and 58.6% were males. Bortezomib and lenalidomide were most frequently used (>50%) in first and second-line treatment respectively among both the ASCT and non-ASCT cohort. The median OS was 122.0 months (95% Cl 115.0-135.0 months) and 54.3 months (95% CI 50.8-58.8 months) for the ASCT and non-ASCT cohort respectively with an incremental decrease in OS in each subsequent line of treatment.ConclusionWe present the largest study to date in the Canadian landscape showing the characteristics, therapy usage, and outcomes among MM patients. This information will be critical in benchmarking current outcomes and provide key insight into areas of unmet needs and gaps for improvement of MM patients nationally.     

Mechanism matters: A 10-year experience of ballistic injuries of the upper extremity

IntroductionUpper Extremity gunshot wounds represent a significant strain on community and hospital resources, and reports of their epidemiology are varied. We hypothesized that demographic and socioeconomic variables would be associated with variable injury patterns and management, and that two distinct populations would be affected by upper extremity ballistic injury based on violent versus accidental, self-inflicted mechanism.Materials & methodsRetrospective review of all adult patients sustaining ballistic injury to the upper extremity at a single urban Level I trauma center over 10 years (n = 797). Demographic, injury pattern, treatment, and outcomes data were collected. Comparisons between groups were conducted with unpaired t-tests and chi-square testing where appropriate.ResultsMost patients were male (89.1%) and mean age was 30.1 years (18-83). Violence accounted for 89.1% of injuries. Black individuals were disproportionately affected at 87% of patients. Shoulder injuries were most common (34%), and wrist least common (7%). Demographics and injury pattern varied significantly between patients sustaining violent injury and those with self-inflicted mechanisms. Patients sustaining violent injury were most often young, Black men more likely to be injured proximally, whereas patients with self-inflicted injuries were more likely to be older, Caucasian men with more comorbidities injured distally. Cumulatively, 35.3% of patients required operative intervention. Distal injuries were more likely operative. The most commonly injured structure across all levels was bone (53%), and 54.3% of fractures required operation. Median follow-up was 24.5 months. Complication rate was 13.6%.ConclusionsGunshot wounds of the upper extremity create complex patterns of injury which vary based on level of injury and mechanism. Violent and self-inflicted injuries occur in dissimilar populations and result in distinctive injury patterns.
