ABSTRACT

BACKGROUND: Hepato-pancreatico-biliary (HPB) patients experience significant risk of preoperative frailty. Studies assessing preventative prehabilitation in HPB populations are limited. This systematic review and meta-analysis evaluates outcomes for HPB patients treated with exercise prehabilitation.

DATA SOURCES: A comprehensive search of MEDLINE (via Ovid), Embase (Ovid), Scopus, Web of Science Core Collection, Cochrane Library (Wiley), ProQuest Dissertations, Theses Global, and Google Scholar was conducted with review and extraction following PRISMA guidelines. Included studies evaluated more than 5 adult HPB patients undergoing ≥ 7-day exercise prehabilitation. The primary outcome was postoperative length of stay (LOS); secondary outcomes included complications, mortality, physical performance, and quality of life.

RESULTS: We evaluated 1778 titles and abstracts and selected 6 (randomized controlled trial, n = 3; prospective cohort, n = 1; retrospective cohort, n = 2) that included 957 patients. Of those, 536 patients (56.0%) underwent exercise prehabilitation and 421 (44.0%) received standard care. Patients in both groups were similar with regards to important demographic factors. Prehabilitation was associated with a 5.20-day LOS reduction (P = 0.03); when outliers were removed, LOS reduction decreased to 1.85 days and was non-statistically significant (P = 0.34). Postoperative complications (OR = 0.70; 95% CI: 0.39 to 1.26; P = 0.23), major complications (OR = 0.83; 95% CI: 0.60 to 1.14; P = 0.24), and mortality (OR = 0.67; 95% CI: 0.17 to 2.70; P = 0.57) were similar. Prehabilitation was associated with improved strength, cardiopulmonary function, quality of life, and alleviated sarcopenia.

CONCLUSIONS: Exercise prehabilitation may reduce LOS and morbidity following HPB surgery. Studies with well-defined exercise regimens are needed to optimize exercise prehabilitation outcomes.

ABSTRACT

OBJECTIVE: Real-world outcomes and prognostic factors in Japanese patients receiving nivolumab therapy for recurrent or metastatic head and neck carcinoma (RMHNC) with an observation period of 1 year have been previously reported. The 1-year follow-up data have been subsequently accumulated, and the long-term real-world outcomes have been analyzed. This study aimed to investigate the 2-year long-term outcomes and prognostic factors associated with the response to nivolumab.

METHODS: This was a multi-institutional retrospective study. In total, 88 RMHNC Japanese patients with squamous cell carcinoma who received nivolumab between May 2017 and May 2018 were retrospectively reviewed. Overall survival (OS), progression-free survival (PFS), and best overall response (BOR) were evaluated. Univariate and multivariable analyses were performed to identify the prognostic factors.

RESULTS: The median follow-up periods for monitoring OS and PFS were 73.1 and 48.1 weeks, respectively. The median OS was 74.1 weeks, and the 2-year survival rate was 33.4%. The median PFS was 18.5 weeks, and the 2-year PFS rate was 22.5%. The BOR rate was 10.2%, 19.3%, 25.0%, and 44.3% in patients who achieved complete response, partial response, stable disease, and progressive disease (PD), respectively. Among the 88 patients with RMHNC, a total of 40 immune-related adverse events (irAEs) were reported in 30 patients. Four patients continued nivolumab, while 84 patients discontinued nivolumab at the data cut-off date. The most common reason for discontinuation was PD in 61 patients, irAEs in 14 patients, and patients’ wishes in 7 patients. Of the 61 patients who discontinued nivolumab because of PD, 28 patients received subsequent treatment. Statistical analyses revealed radiotherapy history, performance status, platinum-refractory carcinoma, irAEs, age, and post-nivolumab treatment as the important prognostic factors associated with OS in patients with RMHNC, and the magnitude of BOR was significantly associated with OS. Additionally, patients with subsequent treatment, including molecular targeted therapy and/or chemotherapy, had significantly prolonged OS compared to patients without subsequent treatment in cases with nivolumab discontinuation because of PD.

CONCLUSION: These findings could be a useful guide for future treatment strategies for head and neck carcinoma. Considering the limitations of our cohort, further larger-scale studies with long-term follow-up are needed to substantiate the results of this study.

ABSTRACT

RATIONALE AND OBJECTIVES: Since the American Board of Radiology (ABR) instituted the new system of board certification, there has been much discussion as to the test’s validity. We decided to evaluate if subjective evaluation of resident performance correlated with ABR Qualifying (Core) Examination performance at this single institution.

MATERIALS AND METHODS: Data regarding resident evaluation scores by attending physicians and passage of board examinations was gathered regarding residents who had taken the ABR Qualifying (Core) Examination from 2013 through 2019 for a total of 42 residents, eight of whom failed the ABR Qualifying (Core) Examination on their first attempt. A univariate analysis comparing scores with resident passage or failure of the ABR Qualifying (Core) Examination on the first attempt and analyses correcting for class year only and class year and number of evaluations was performed.

RESULTS: The non-weighted average evaluation score of years 1, 2, and 3 was 80.24% for those who failed the ABR Qualifying (Core) Examination and 83.71 % for those who passed. On univariate analysis along with analyses correcting for class year only and class year along with number of evaluations, there was a statistically significant correlation with decreased evaluation scores averaged over the three years of residency and failure of the ABR Qualifying (Core) Examination (p = 0.0102, p = 0.003, and p = 0.0043). The statistical significance held for the average numerical score in each individual year of training in all analyses except for year 1 of the univariate analysis (p = 0.1264).

CONCLUSION: At the studied institution, there was a statistically significant correlation between lower subjective faculty evaluation scores and failure of the ABR Qualifying (Core) Examination.

ABSTRACT

BACKGROUND: The Nine Hole Peg Test (NHPT) is one of the most frequently used tools to assess manual dexterity. However, no kinematic parameters are provided to describe the quality of the motor performance, since time is the only score.

PURPOSE: To investigate test-retest and intra-rater reliability, correlation with clinical test score, and discriminant validity of kinematic indexes during NHPT.

STUDY DESIGN: A clinical measurement study.

METHODS: Twenty-five healthy right-handed volunteers performed the NHPT. An experienced physiotherapist administered two sessions at a 6-hour interval with two trials for dominant and non-dominant upper limbs. An optoelectronic system was used to detect NHPT performance, which was divided into nine consecutive peg-grasp, peg-transfer, peg-in-hole, hand-return phases, and one final removing phase. Outcome measures were total and single phases times, normalized jerk, mean, peak and time-to-peak of velocity, curvature index during peg-grasp and hand-return phases, and trunk 3D displacement. The statistical analysis included Intraclass Correlation Coefficients (ICCs) for test-retest and intra-rater reliability, Pearson’s coefficients for correlation with the NHPT score, and paired t-tests for discriminant validity.

RESULTS: Test-retest reliability was excellent for trunk rotation (ICC: 0.91) and good to moderate for the other indexes (ICCs: 0.89-0.61). Intra-rater reliability was excellent for total and removing times (ICCs: 0.91 and 0.94) and good to moderate for the other indexes (ICCs: 0.84-0.66), except for trunk inclination (ICC: 0.37). NHPT phases, normalized jerk, mean velocity, peak of velocity, time-to-peak and curvature index correlated with total time (r-score: 0.8-0.3). NHPT phases and most kinematic indexes discriminated the dominant from non-dominant upper limb, with the greatest effect size for normalized jerk during hand-return (d = 1.16).

CONCLUSIONS: Kinematic indexes during NHPT can be considered for manual dexterity assessment. These indexes may allow for the detection of kinematic changes responsible for NHPT score variations in healthy subjects or patients with upper limb impairments.

ABSTRACT

BACKGROUND: Critical illness from COVID-19 is associated with prolonged hospitalization and high mortality rates. Extracorporeal membrane oxygenation is used for refractory severe acute respiratory distress syndrome in COVID-19 with outcomes comparable to other indications for extracorporeal membrane oxygenation. However, long-term functional outcomes have yet to be fully elucidated.

METHODS: We performed a retrospective chart review of 24 consecutive patients who required extracorporeal membrane oxygenation due to COVID-19 associated severe acute respiratory distress syndrome and survived to hospital discharge. After hospitalization, we contacted patients and administered the Patient-Reported Outcomes Measurement Information System (PROMIS) Global-10 tool to assess longer-term outcomes. We abstracted demographics, clinical course, outcomes, and disposition variables from the electronic medical record. Descriptive statistical analysis was used on the retrospective data collection.

RESULTS: Inpatient data were analyzed for 24 patients, and 21 of 24 (88%) patients completed the Patient-Reported Outcomes Measurement Information System tool at an average of 8.8 months posthospitalization. At hospital discharge, 62.5% of patients had ongoing oxygen requirements (nasal cannula, trach collar, or mechanical ventilation); 70.8% were discharged to a location other than home. However, at the time of follow-up, only 9.5% of patients required supplemental oxygen, all tracheostomies had been removed, and all patients resided at home. Patients reported relatively high levels of global physical function, and though there was a high reported incidence of fatigue, overall pain scores were low.

CONCLUSION: Long-term outcomes after extracorporeal membrane oxygenation for severe acute respiratory distress syndrome from coronavirus disease 2019 are promising. Extracorporeal membrane oxygenation therapy may confer morbidity benefits in patients with coronavirus disease and remains a valuable modality with excellent functional outcomes and preserved quality of life for survivors.

ABSTRACT

BACKGROUND: From 1991-2014, all major burn centers of the German-speaking countries participated in a multicenter study in which essentially demographic data were collected. Individual patient data was located at the particular burn centers and only cumulated data were summarized annually for presentation. Retrospective statistical analysis of the entire data collection and identification of subgroups was not possible. In 2015 the German Burn Registry was established for prospective collection of individual patient data as a tool for quality management (QM) and for scientific analyses.

METHODS: A working group was formed to ensure the development and administration of the registry. From the official start of the German Burn Registry at the beginning of the year 2015 prospective data collection was realized with an individualized, web-based data collection software in a pseudonymized way. Selected data analysis was performed for the first 5 years of data collection. Severely burned adults and all hospitalized children with burn injuries were documented in the registry.

RESULTS: The German Burn Registry was successfully established. 64 burn divisions have already been registered. 18,891 patients were documented over 5 years, of which 58% where children (<16 years). Mean ABSI Score was 4 (children: 3, adults: 6) with a mortality rate of 3.8.0% (children: 0.2%, adults: 9.3%). Children were hospitalized for an average of 7 days, whereas adults were discharged after 18 days.

CONCLUSION: A registry is mandatory for quality assurance in burn medicine, since realization of randomized studies is difficult due to the heterogeneity of burn injuries. The German Burn Registry already is one of the biggest burn registries in Europe. Several scientific projects, based on the registry database, are in working process or have already been published.

ABSTRACT

PURPOSE: Pediatric patients with Crohn’s disease often require colectomies. The laparoscopic approach is considered safe, but there is little national data on outcomes and readmissions in this population.

METHODS: The Nationwide Readmissions Database was queried from 2010 to 2014 for patients ≤ 18 years who underwent colectomy for Crohn’s disease during index admission. Patients were stratified by operative approach: laparoscopic versus open. Outcomes were compared with standard statistical methods.

RESULTS: There were 2833 patients (47% female) who underwent a colectomy via laparoscopic (58%) vs. open (42%) approach. Index admissions were elective 55% of the time. Most operations were right hemicolectomy (86%), followed by total colectomy (8%). Of the study population, 489 (17%) were diverted with an ostomy. Readmission rates at 30 days and 1 year were 9% and 18%, respectively. The most common diagnoses at readmission were intra-abdominal infection (16%), small bowel obstruction (16%), and surgical site infection (9%). Laparoscopy was more commonly performed during elective admissions (63% vs. 44%), for patient with private insurance (72% vs. 39%), and for patients in the highest income quartile (66% vs. 48% in the lowest income quartile), all p<0.001. Length of stay was longer on index admission for open colectomy (8[5-12] days vs. 6[4-11] days, p<0.001), while cost was similar ($17,754[$12,375-$30,625] vs. $17,017[$11,219-$27,336], p = 0.104). There were no differences in readmission rate, intraabdominal infection or small bowel obstruction.

CONCLUSION: In pediatric patients, laparoscopic colectomy for Crohn’s disease is safe and is associated with shorter hospitalization and equivalent hospital costs compared to the open procedure. Socioeconomic disparities in laparoscopic utilization exist and warrant future investigation.

LEVEL OF EVIDENCE: Level III.

ABSTRACT

BACKGROUND: Adolescents with blunt solid organ injuries (BSOI) are cared for at both pediatric trauma centers (PTC) and adult trauma centers (ATC). Over the past decade, treatment strategies have shifted towards non-operative management with reported favorable outcomes. The aim of this study was to compare management strategies and outcomes between PTC and ATC.

METHODS: We queried the 2016-2018 Trauma Quality Improvement Program (TQIP) datasets to identify adolescents between the ages of 16 and 19 with BSOI. Characteristics were stratified by center type (pediatric or adult) for comparative analyses. Separate logistic regressions were used to assess the association of hospital type, location of injury, age, gender, weight, Glascow Coma Score (GCS), Injury Severity Score (ISS), and intensive care unit (ICU) admissions for outcomes of interest.

RESULTS: Among the 3,011,310 patients enrolled in the 2016-2018 TQIP datasets, 106,892 (3.5%) had a BSOI ICD9/10 code. Of those, 9,193 (8.6%) were between 16 and 19 years of age and included in this analysis. Within this cohort, 6,073 (66.1%) were managed at an ATC and 3,120 (33.9%) were managed at a PTC. While statistically different, there were no clinically relevant differences for age, weight, and sex between groups. A significantly higher ISS and lower GCS score were observed among those admitted to ATC compared to PTC. ICU admissions were more frequent at ATC. Number of blood transfusions by 4 h after presentation were also higher among those admitted to an ATC. Despite a lower ISS and higher GCS at presentation, mortality was higher among those treated at a PTC with an odds ratio (95% confidence interval) of 2.42 (1.31-4.53). After excluding adolescents with a traumatic brain injury, a common cause of mortality among adolescent trauma patients, these differences in outcomes persisted.

CONCLUSIONS: Our data suggest that adolescents with BSOI managed at a PTC are less likely to receive blood transfusions by 4 h of admission or be admitted to the ICU than those managed at an ATC. However, this more conservative approach may come at the expense of higher overall mortality. Further work is needed to understand these differences and determine if PTC need to be more aggressive in managing BSOI.

ABSTRACT

Three-dimensional bone reconstructions from medical imaging are essential for biomechanical modelling and are growing tools in clinics. Several methods of lower limbs reconstruction from biplanar radiographs have been proposed in the literature but with significant operator dependence. A novel reconstruction method based on reduced manual annotation, statistical shape models and fully automatic adjustments was proposed in this study. While significantly reducing operator intervention, the proposed method demonstrated similar or better precision than previous approaches on clinical parameters. Meanwhile, shape accuracy was improved to around 1mm. By quasi-automating the 3D reconstruction without loss of accuracy and precision, the proposed approach is a considerable step towards extensive use of 3D personalized models in clinical routine and large cohort biomechanical studies.

ABSTRACT

Purpose: The purpose of this study was to compare video modelling (VM) to a Picture Exchange Communication System (PECS) aimed at improving the oral hygiene of children with autism spectrum disorder (ASD). Methods: This prospectively stratified randomized controlled trial was conducted on 50 children with mild and moderate ASD. Children were assigned into two balanced groups. The control group was educated through PECS, and the intervention group was exposed to VM. Oral hygiene was assessed using the Oral Hygiene Index-simplified (OHI-s) on four occasions (at baseline and at three, six, and 12 months). Quantitative data were analyzed using Fisher’s exact test and a t-test at a five percent significance level and 95 percent confidence interval (95% CI), respectively. Spearman’s rank correlation coefficient (r) was used to correlate baseline characteristics in both groups to obtain average OHI-s scores. Results: The VM group showed a statistically significant reduction in average OHI-s scores compared to the PECS group over the follow-up period (P<0.001). At three, six, and 12 months, the OHI-s mean differences were 0.30 (95% CI equals 0.14 to 0.47), 0.58 (95% CI equals 0.39 to 0.77), and 0.57 (95% CI equals 0.30 to 0.84), respectively. For both groups, the severity of ASD was moderately associated with OHI-s scores at 12 months. Conclusion: Video modelling showed superior results in improving the oral hygiene of children with autism spectrum disorder compared to the Picture Exchange Communication System.
