Changes in Pediatric Sports Injury Presentation During the COVID-19 Pandemic: A Multicenter Analysis.
Orthopaedic journal of sports medicine
2021; 9 (4): 23259671211010826
The current coronavirus 2019 (COVID-19) pandemic has prompted a multitude of public health response measures including social distancing, school cancellations, and cessation of organized sports.To examine the impact of COVID-19 and corresponding public health measures on the characteristics of common pediatric musculoskeletal injuries associated with sports.Cohort study; Level of evidence, 3.This was a multicenter retrospective cohort study comparing patients with sports injuries presenting to 3 geographically diverse level I pediatric trauma hospitals and outpatient orthopaedic surgery clinics in the United States during the COVID-19 pandemic and a prepandemic period at the same institutions. Patients were included if they presented for care between February 15 and July 15 in 2020 (pandemic cohort) or between March 15 and April 15 in 2018 and 2019 (prepandemic cohort).Included were 1455 patients with an average age of 12.1 ± 4.5 years. When comparing patients presenting in 2018 and 2019 with those presenting in 2020, we observed a decrease in mean age during the pandemic (12.6 ± 4.0 vs 11.0 ± 5.2 years; P = .048). Additionally, a decrease in the proportion of injuries attributed to sports (48.8% vs 33.3%; P < .001) and those occurring at school (11.9% vs 4.0%; P = .001) was observed. The proportion of injuries attributable to clavicle fractures increased during the early stages of the pandemic (13.2% vs 34.7%; P < .001). There was no statistically significant delay to care in injuries presenting during the pandemic (41.5 ± 141.2 vs 19.23 ± 79.1 days; P = .175).Across 3 tertiary care institutions, patients were seen without significant delay during the pandemic. We observed a significant decline in pediatric musculoskeletal injuries associated with sports during the COVID-19 pandemic. This decrease has been accompanied by a shift in both injury type and mechanism.

A Multidomain Approach to Assessing the Convergent and Concurrent Validity of a Mobile Application When Compared to Conventional Methods of Determining Body Composition.
Sensors (Basel, Switzerland)
2020; 20 (21)
Determining body composition via mobile application may circumvent limitations of conventional methods. However, the accuracy of many technologies remains unknown. This investigation assessed the convergent and concurrent validity of a mobile application (LS) that employs 2-dimensional digital photography (LS2D) and 3-dimensional photonic scanning (LS3D). Measures of body composition including circumferences, waist-to-hip ratio (WHR), and body fat percentage (BF%) were obtained from 240 healthy adults using LS and a diverse set of conventional methods-Gulick tape, bioelectrical impedance analysis (BIA), and skinfolds. Convergent validity was consistently high-indicating these methods vary proportionally and can thus reliably detect changes despite individual measurement differences. The span of the Limits of Agreement (LoA) using LS were comparable to the LoA between conventional methods. LS3D exhibited high agreement relative to Gulick tape in the measurement of WHR, despite poor agreement with individual waist and hip circumferences. In BF%, LS2D exhibited high agreement with BIA and skinfold methods, whereas LS3D demonstrated low agreement. Interestingly, the low inferred bias between LS3D and DXA using existing data suggests that LS3D may have high agreement with dual-energy x-ray absorptiometry. Overall, the suitability of LS2D and LS3D to replace conventional methods must be based on an individual user's criteria.

Prospectively Assigned AAST Grade versus Modified Hinchey Class and Acute Diverticulitis Outcomes.
The Journal of surgical research
The American Association for the Surgery of Trauma (AAST) recently developed a classification system to standardize outcomes analyses for several emergency general surgery conditions. To highlight this system's full potential, we conducted a study integrating prospective AAST grade assignment within the electronic medical record.Our institution integrated AAST grade assignment into our clinical workflow in July 2018. Patients with acute diverticulitis were prospectively assigned AAST grades and modified Hinchey classes at the time of surgical consultation. Support vector machine-a machine learning algorithm attuned for small sample sizes-was used to compare the associations between the two classification systems and decision to operate and incidence of complications.67 patients were included (median age of 62 y, 40% male) for analysis. The decision for operative management, hospital length of stay, intensive care unit admission, and intensive care unit length of stay were associated with both increasing AAST grade and increasing modified Hinchey class (all P < 0.001). AAST grade additionally showed a correlation with complication severity (P = 0.02). Compared with modified Hinchey class, AAST grade better predicted decision to operate (88.2% versus 82.4%).This study showed the feasibility of electronic medical record integration to support the full potential of AAST classification system's utility as a clinical decision-making tool. Prospectively assigned AAST grade may be an accurate and pragmatic method to find associations with outcomes, yet validation requires further study.

Prospective Study of Short-Term Quality-of-Life After Traumatic Rib Fractures.
The journal of trauma and acute care surgery
Post-discharge convalescence after traumatic rib fractures remains unclear. We hypothesized that patients with rib fractures, even as an isolated injury, have associated poor QoL after discharge.We prospectively enrolled adult patients at our Level I trauma center with rib fractures between July 2019 and January 2020. We assessed QoL at 1 and 3-months after discharge using the Trauma-specific Quality-of-Life (T-QoL: 43-question survey evaluating five QoL domains on a four-point Likert scale. "4" indicates optimal and "1" worst QoL) and supplementary questionnaires. We used generalized estimating equations to assess T-QoL score trends over time and effect of age, sex, injury pattern, self-perceived injury severity, and injury severity score.We enrolled 139 patients (108 completed the first and 93 completed both surveys). Three months after discharge, 33% of patients were not working at pre-injury capacity and 7% were still using opioid analgesia. Suffering rib fractures most impacted recovery and resilience (T-QoL score, mean [robust standard error] at 1-month: 2.7[0.1], 3-months: 3.0[0.1]) and physical well-being domains (1-month: 2.5[0.1]; 3-months 2.9[0.1]). QoL improved over time across all domains. Compared with patients who perceived their injuries as mild/moderate, patients who perceived their injuries as severe/very severe reported worse T-QoL scores across all domains. In contrast, injury severity score did not affect QoL. Patients aged ≥65 years (-0.6[0.1]) and females (-0.6[0.2]) reported worse functional engagement compared with those aged ≤65 years and males, respectively.We found that patients with traumatic rib fractures experience suboptimal QoL after discharge. QoL improved over time, but even three months after discharge, patients reported challenges performing activities of daily living, slower-than-expected recovery, and not returning to work at pre-injury capacity. Perception of injury severity had a large effect on QoL. Patients with rib fractures may benefit from close short-term follow-up.Prognostic and Epidemiological LEVEL OF EVIDENCE: Level III.
