A Review of Parameterizations for Enthalpy and Momentum Fluxes from Sea Spray in Tropical Cyclones
Authors: Sroka Sydney , Emanuel Kerry 
Published: June 2021

AbstractThe intensity of tropical cyclones is sensitive to the air-sea fluxes of enthalpy and momentum. Sea spray plays a critical role in mediating enthalpy and momentum fluxes over the ocean’s surface at high wind speeds, and parameterizing the influence of sea spray is a crucial component of any air-sea interaction scheme used for the high wind regime where sea spray is ubiquitous. Many studies have proposed parameterizations of air-sea flux that incorporate the microphysics of sea spray evaporation and the mechanics of sea spray stress. Unfortunately, there is not yet a consensus on which parameterization best represents air-sea exchange in tropical cyclones, and the different proposed parameterizations can yield substantially different tropical cyclone intensities. This paper seeks to review the developments in parameterizations of the sea spray-mediated enthalpy and momentum fluxes for the high wind speed regime and to synthesize key findings that are common across many investigations.

Background Official conference participants (OCPs) consisting of speakers, moderators, discussants, and presenters) with conflicts of interest (COI) could negatively influence the audience’s ability to fairly evaluate information if their COI is not properly disclosed. We aim to examine the patterns of COI disclosures by OCPs and the nature and extent of financial compensation at 3 annual trauma conferences. Methods A retrospective cohort analysis of COI disclosures of OCPs, in the EAST, WTA, and AAST Annual Meetings from 2016 to 2019. The Open Payments Database (OPD) was used to describe the nature and extent of financial compensation. Descriptive statistics and independent sample t-tests were performed with significance defined as P < .05. Results Eastern Association for the Surgery of Trauma: conflicts of interest ranged from 3.8 to 6.0% of OCPs. Moderators, discussants, and presenters comprised decreasing proportions disclosing COIs, whereas speakers comprised an increasing proportion. Western Trauma Association : conflicts of interest ranged from 1.3 to 6.8% of OCPs. Moderators comprised an increasing proportion whereas speakers comprised a decreasing proportion. American Association for the Surgery of Trauma: conflicts of interest ranged from 3.6 to 5.4% of OCPs. Speakers, moderators, and presenters comprised progressively decreasing proportions, whereas discussants comprised an increasing proportion. Participants who did not disclose a COI comprised the majority of payment recipients in the OPD. Conclusion Official conference participants who disclosed a COI varied between EAST, WTA, and AAST Annual Meetings from 2016 to 2019. Implementation of standardized COI disclosure policies with explicitly communicated definitions/categories can maximize the participants’ understanding of the disclosure process, translate into improved COI reporting, and preserve an evidence-based environment that is free from commercial influence for physicians to teach and learn.

Published: June 2021

Background Work hour restrictions have been imposed by the Accreditation Council for Graduate Medical Education since 2003 for medical trainees. Many acute care surgeons currently work longer shifts but their preferred shift length is not known. Methods The purpose of this study was to characterize the distribution of the current shift length among trauma and acute care surgeons and to identify the surgeons’ preference for shift length. Data collection included a questionnaire with a national administration. Frequencies and percentages are reported for categorical variables and medians and means with SDs are reported for continuous variables. A chi-square test of independence was performed to examine the relation between call shift choice and trauma center level (level 1 and level II), age, and gender. Results Data from 301 surgeons in 42 states included high-level trauma centers. Assuming the number of trauma surgeons in the United States is 4129, a sample of 301 gives the survey a 5% margin of error. The median age was 43 years (M = 46, SD = 9.44) and 33% were female. Currently, only 23.3% of acute care surgeons work a 12-hour shift, although 72% prefer the shorter shift. The preference for shorter shifts was statistically significant. There was no significant difference between call shift length preference and trauma center level, age, or gender. Conclusion Most surgeons currently work longer than 12-hour shifts. Yet, there was a preference for 12-hour shifts indicating there is a gap between current and preferred shift length. These findings have the potential to substantially impact staffing models.

Objective: To analyze the factors influencing the diagnosis and treatment of tracheobronchial foreign bodies (TFBs) in children. Methods: The clinical data of 300 consecutive children with suspected TFBs who were admitted to our department between January 2016 and December 2019 were retrospectively collected, including demographics, diagnosis, history of foreign body inhalation, preoperative chest computed tomography (CT) findings, duration of foreign body retention, time from admission to operation, operation duration, duration of hospitalization, and complications. Results: Among the 300 cases, the male:female ratio was 193:107, and the age range was 6 months to 12 years (median age: 19 months). A total of 291 cases (97.0%) involved TFBs confirmed by rigid bronchoscopy, while the other 9 cases (3.0%) involved bronchopneumonia. The diagnostic accuracy, sensitivity, and specificity of a history of foreign body inhalation and chest CT were 96.0%, 98.6%, and 11.1% and 97.7%, 97.6%, and 100%, respectively. The duration of hospitalization, time from admission to operation, and operation duration were all related to bronchopneumonia ( P < .05). Conclusions: A detailed history, adequate physical examination, and preoperative imaging examination help improve the diagnostic accuracy. Preoperative bronchopneumonia in children with TFBs will increase the surgical risks and treatment costs, prolonging the duration of hospitalization.

Published: June 2021

Background: Although minimal clinically important difference (MCID), Patient Acceptable Symptom State (PASS), and substantial clinical benefit (SCB) have been defined for hip-specific legacy patient-reported outcome measures, these metrics have not been defined for the Patient-Reported Outcomes Measurement Information System (PROMIS) instruments for patients undergoing hip arthroscopy. Purpose: To define the MCID, PASS, and SCB thresholds for the PROMIS Physical Function (PF) computerized adaptive test (CAT) and PROMIS Pain Interference (PI) instruments in patients undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS). Study Design: Cohort study (Diagnosis); Level of evidence, 2. Methods: Patients undergoing primary hip arthroscopy between August 2018 and January 2019 for the treatment of FAIS were retrospectively analyzed. Patients were administered the PROMIS-PF, PROMIS-PI, Hip Outcome Score (HOS)–Activities of Daily Living, HOS–Sports Subscale, modified Harris Hip Score, and International Hip Outcome Tool–12 preoperatively and at 1 year postoperatively. MCID was calculated using the distribution method, whereas PASS and SCB were calculated using an anchor-based method. Patients achieving clinically significant outcomes (CSOs) were compared with those who did not achieve CSOs via chi-square and independent-samples t tests, and a multivariate logistic regression was conducted to determine predictors of CSO achievement. Results: 124 patients with a mean age of 32.7 ± 12.3 years were included in the analysis. The threshold scores required to achieve MCID, PASS, and SCB, respectively, were as follows: PROMIS-PI (–3.1, 53.7, 51.9) and PROMIS-PF (3.3, 47.0, 49.9). Patients achieved any MCID, PASS, and SCB for PROMIS scores at a rate of 89.0%, 71.8%, and 62.1%, respectively, compared with 87.1%, 76.6%, and 71.8% for legacy patient-reported outcome measurements. For PROMIS-PF, higher preoperative PROMIS-PF score was a positive predictor of CSO achievement, and patients achieving SCB were significantly younger (30.3 ± 12 vs 35.6 ± 12 years; P = .017) with significantly lower body mass index (BMI) (24.7 ± 6.4 vs 27.9 ± 7; P = .009). Preoperative chronic pain and history of orthopaedic surgery were negative predictors of PROMIS-PI CSO achievement, whereas higher (worse) preoperative PROMIS-PI scores were a positive predictor. Conclusion: Our study defined the MCID, PASS, and SCB for the PROMIS-PF CAT and PROMIS-PI CAT at 1 year postoperatively. Patients with higher preoperative PROMIS scores, younger age, and lower BMI were more likely to achieve CSO, whereas preoperative chronic pain and history of orthopaedic surgery were negative predictors of CSO achievement.

Published: June 2021

Background: Biomechanical studies on anterior cruciate ligament (ACL) injuries and reconstructions are based on ACL transection instead of realistic injury trauma. Purpose: To replicate an ACL injury in vitro and compare the laxity that occurs with that after an isolated ACL transection injury before and after ACL reconstruction. Study Design: Controlled laboratory study. Methods: Nine paired knees were ACL injured or ACL transected. For ACL injury, knees were mounted in a rig that imposed tibial anterior translation at 1000 mm/min to rupture the ACL at 22.5° of flexion, 5° of internal rotation, and 710 N of joint compressive force, replicating data published on clinical bone bruise locations. In contralateral knees, the ACL was transected arthroscopically at midsubstance. Both groups had ACL reconstruction with bone–patellar tendon–bone graft. Native, ACL-deficient, and reconstructed knee laxities were measured in a kinematics rig from 0° to 100° of flexion with optical tracking: anterior tibial translation (ATT), internal rotation (IR), anterolateral (ATT + IR), and pivot shift (IR + valgus). Results: The ACL ruptured at 26 ± 5 mm of ATT and 1550 ± 620 N of force (mean ± SD) with an audible spring-back tibiofemoral impact with 5o of valgus. ACL injury and transection increased ATT ( P < .001). ACL injury caused greater ATT than ACL transection by 1.4 mm (range, 0.4-2.2 mm; P = .033). IR increased significantly in ACL-injured knees between 0° and 30° of flexion and in ACL transection knees from 0° to 20° of flexion. ATT during the ATT + IR maneuver was increased by ACL injury between 0° and 80° and after ACL transection between 0° and 60°. Residual laxity persisted after ACL reconstruction from 0° to 40° after ACL injury and from 0° to 20° in the ACL transection knees. ACL deficiency increased ATT and IR in the pivot-shift test ( P < .001). The ATT in the pivot-shift increased significantly at 0° to 20° after ACL transection and 0° to 50° after ACL injury, and this persisted across 0° to 20° and 0° to 40° after ACL reconstruction. Conclusion: This study developed an ACL injury model in vitro that replicated clinical ACL injury as evidenced by bone bruise patterns. ACL injury caused larger increases of laxity than ACL transection, likely because of damage to adjacent tissues; these differences often persisted after ACL reconstruction. Clinical Relevance: This in vitro model created more realistic ACL injuries than surgical transection, facilitating future evaluation of ACL reconstruction techniques.
Functional Ankle Range of Motion but Not Peak Achilles Tendon Force Diminished With Heel-Rise and Jumping Tasks After Achilles Tendon Repair
Authors: Zellers Jennifer A. , Baxter Josh R. , Grävare Silbernagel Karin 
Published: June 2021

Background: Deficits in sporting performance after Achilles tendon repair may be due to changes in musculotendinous unit structure, including tendon elongation and muscle fascicle shortening. Purpose/Hypothesis: The purpose was to discern whether Achilles tendon rupture reduces triceps surae muscle force generation, alters functional ankle range of motion, or both during sports-related tasks. We hypothesized that individuals who have undergone Achilles tendon repair lack the functional ankle range of motion needed to complete sports-related tasks. Study Design: Descriptive laboratory study. Methods: The study included individuals 1 to 3 years after treatment of Achilles tendon rupture with open repair. Participants (n = 11) completed a heel-rise task and 3 jumping tasks. Lower extremity biomechanics were analyzed using motion capture. Between-limb differences were tested using paired t test. Results: Pelvic vertical displacement was reduced during the heel-rise (mean difference, −12.8%; P = .026) but not during the jumping task ( P > .1). In the concentric phase of all tasks, peak ankle plantarflexion angle (range of mean difference, −19.2% to −48.8%; P < .05) and total plantar flexor work (defined as the area under the plantar flexor torque – ankle angle curve) (range of mean difference, −9.5% to −25.7%; P < .05) were lower on the repaired side relative to the uninjured side. No significant differences were seen in peak Achilles tendon load or impulse with any of the tasks. There were no differences in plantar flexor work or Achilles tendon load parameters during eccentric phases. Conclusion: Impaired task performance or increased demands on proximal joints were observed on the repaired side in tasks isolating ankle function. Tasks that did not isolate ankle function appeared to be well recovered, although functional ankle range of motion was reduced with rupture. Reduced plantar flexor muscle-tendon unit work supports previous reports that an elongated tendon and shorter muscle fascicles caused by Achilles tendon rupture constrain functional capacity. Achilles tendon peak load and impulse were not decreased, suggesting that reduced and shifted functional ankle range of motion (favoring dorsiflexion) underlies performance deficits. Clinical Relevance: These findings point to the need to reduce tendon elongation and restore muscle length of the triceps surae after Achilles tendon rupture in order to address musculature that is short but not necessarily weak for improved performance with sports-related activities.
Mechanical Tension-Stress in Alveolar Cleft Repaired With Autogenous Bone in Canine Models
Authors: Liu Anqi , Huang Jialiang 
Published: June 2021

Objective: Cleft lip and/or palate is a common birth defect worldwide, always accompanied by alveolar cleft. However, the success rate of secondary alveolar bone grafting is unsatisfactory. Rapid maxillary expansion (RME) often used after bone transplantation provides functional stimulation for bone graft area. This study aimed to investigate the effect of RME force on the bone graft area and midpalatal suture, and screen out the most suitable loaded force and loaded teeth, so as to provide a reference for clinical treatment. Methods: Fourteen 24-week-old male beagles were assigned randomly to 3 groups: blank control, autogenous, and autogenous with RME. Three-dimensional finite element analysis was conducted to evaluate the distribution and value of the stress in the model. The maxillae were collected and subjected to radiography and helical computed tomography to evaluate new bone formation in the graft area. Van Gieson’s Picrofuchsin staining was performed for histomorphological observation. Results: After 8 weeks of RME treatment, new bone formation of the dogs was markedly accelerated, and bone resorption was significantly reduced compared with the untreated dogs or those only treated with autogenous iliac bone. The treatment with RME evidently made the bone trabecula more abundant and the area of bone formation larger. Three-dimensional finite element analysis showed that the clinical effect can be achieved by using canine teeth as the loaded teeth and applying force of 10 MPa. Conclusion: Rapid maxillary expansion after bone grafting had a positive effect on osteogenesis in a canine model of alveolar cleft.

Published: June 2021

This study explores how parenting couples use their relationship to support each other after their child’s autism diagnosis by assessing the role of dyadic coping and parenting sense of competence as predictors of their coparenting quality. Mothers and fathers raising a child on the spectrum ( N = 70 couples) individually completed self-report questionnaires measuring stress appraisal, dyadic coping, parenting sense of competence, and coparenting. Parents were recruited 1–36 months after their child’s autism diagnosis and data were analyzed using the actor-partner interdependence model. Parents’ dyadic coping and sense of competence were related to their level of coparenting. Partner effects were found as mothers’ dyadic coping was positively linked to fathers’ coparenting and a higher sense of competence among fathers predicted mothers’ coparenting. Further research is needed to understand how these effects evolve throughout the child’s development stages. Lay abstract We investigated how couples support each other after their child’s autism diagnosis and whether this affects the way they work together to raise their child. We recruited 70 couples raising a child on the autism spectrum. Both partners were asked to complete the same questionnaires measuring how they perceived the experience of having a child on the autism spectrum, how they used their relationship to support each other during stressful situations, how competent they felt completing their parenting tasks, and the coparenting relationship to explore how they worked together as a team when parenting their child. Parents participated in the study 1–36 months after their child’s autism diagnosis. We used statistical techniques that allowed us to see the impact mothers and fathers had on each other. Overall, parents who felt more competent and supported by their partner worked better as a team to raise their child on the spectrum. Fathers invested in the coparenting relationship more when mothers felt more supported by fathers. Mothers invested in the coparenting relationship more when fathers felt more competent parenting their child. Further research is needed to better understand how we can support couples as their child gets older.
Language changes medical judgments and beliefs

Published: June 2021

Aims and objectives: How health risks are communicated can have a substantial impact on medical judgments and choice. Here, we examine whether the language used to process health-related information systematically changes bilinguals’ perceptions and preferences. Methodology: Chinese-English bilinguals were presented with 10 medical scenarios in either their native language (Mandarin Chinese; n = 76) or a second language (American English; n = 84) and made judgments regarding their familiarity with the medical conditions and the perceived severity of the possible symptoms (incurability, emotional distress, physical pain, social harm). Participants then rated their agreement with statements pertaining to beliefs about medical decision-making (trust in the good intentions of doctors, acceptability of challenging doctors, importance of involving family, preference for standard treatments, preference for experimental treatments). Data and analysis: Linear mixed-effects models were constructed for judgments of medical conditions and for beliefs regarding medical decision-making. Findings and conclusions: Medical conditions were perceived to be easier to cure, less physically painful, and less emotionally distressing when processed in the second language, English. Using English also increased endorsement of beliefs (such as challenging doctors’ opinions and accepting experimental treatments) that were more consistent with individualistic than with collectivistic norms. We propose that the activation of emotions and values is linked to language, with consequences for how individuals make decisions that impact their health and well-being. Originality: The present study is among the first to systematically examine the interactive psychological impact of language context and experience on judgments and beliefs in an applied medical domain. Significance: With millions of practitioners and patients worldwide making medical decisions in a combination of native and non-native languages, the present findings highlight the need to account for language, including language use, context, and experience, in order to optimize health-related communication and judgments.

Background The burden of stroke is increasing in India; stroke is now the fourth leading cause of death and the fifth leading cause of disability. Previous research suggests that the incidence of stroke in India ranges between 105 and 152/100,000 people per year. However, there is a paucity of available data and a lack of uniform methods across published studies. Aim To identify high-quality prospective studies reporting the epidemiology of stroke in India. Summary of review A search strategy was modified from the Cochrane Stroke Strategy and adapted for a range of bibliographic databases from January 1997 to August 2020. From 7717 identified records, nine studies were selected for inclusion; three population-based registries, a further three population-based registries also using community-based ascertainment and three community-based door-to-door surveys. Studies represented the four cities of Mumbai, Trivandrum, Ludhiana, Kolkata, the state of Punjab, and 12 villages of Baruipur in the state of West Bengal. The total population denominator was 22,479,509 and 11,654 (mean 1294 SD 1710) people were identified with incident stroke. Crude incidence of stroke ranged from 108 to 172/100,000 people per year, crude prevalence from 26 to 757/100,000 people per year, and one-month case fatality rates from 18% to 42%. Conclusions Further high-quality evidence is needed across India to guide stroke policy and inform the development and organization of stroke services. Future researchers should consider the World Health Organization STEPwise approach to Surveillance framework, including longitudinal data collection, the inclusion of census population data, and a combination of hospital-registry and comprehensive community ascertainment strategies to ensure complete stroke identification.
