- Abstract
Females are at greatest risk for reinjury after return to sport (RTS) following anterior cruciate ligament (ACL) reconstruction (ACLR). The reasons for these sex differences, however, remain unclear. Psychological factors such as kinesiophobia have been identified as a potential predictor for reinjury following RTS. Studies investigating kinesiophobia have identified sex differences, yet whether this holds in the ACLR population remains unknown. The purpose of this study was to examine whether there are sex differences in kinesiophobia and other psychological factors, such as readiness to RTS and self-reported pain in the ACLR population. A total of 20 participants, eleven males (23.0 ± 8.4 years, 178.9 ± 7.6 cm, 76.8 ± 10.4 kg) and 9 females (19.6 ± 5.3 years, 165.1 ± 4.0 cm, 73.2 ± 25.0 kg) voluntarily participated in this study. The Tampa Scale for Kinesiophobia (TSK-11), Anterior Cruciate Ligament Return to Sport After Injury (ACL-RSI) scale, and self-reported pain using a visual analog scale (VAS) were administered after clearance for RTS (10.5 ± 2.3 months post-ACLR). Statistical significance was set a priori at p<0.05. A significant difference between sexes was observed for the ACL-RSI with males reporting a significantly higher score (92.82±16.16) compared to females (77.0±15.54; p = 0.040). There were no significant differences between sexes for VAS for pain (males = 4.55 ± 6.50; females = 1.22 ± 3.31; p = 0.228) and TSK-11 (males = 18.73 ± 3.17; females = 19.67 ± 4.61; p = 0.596). The results of this study demonstrated males had significantly higher ACL-RSI scores than females, suggesting males may have higher psychological readiness following clearance for RTS. This study did not demonstrate significant differences between sexes for kinesiophobia or pain level. Caution in interpretation of results is warranted due to the small sample size, highlighting the need for further research in this area., Competing Interests: Jonathan Riboh receives funding for and/or has the following disclosures: Arthrex consultant, Smith & Newphew Consultant, Ptotect 3D Scientific Board and stock options, Pendria scientific board and stock options Alison Toth- Vericel Corp Advisory board, speakers bureau, Fellowship support from arthres, smith & newphew, MitekDepuy, Breg Other authors have declared that no competing interets exist., (Copyright: © 2024 Robby et al.

- Abstract
Introduction: A palliative care approach can improve quality-of-life for people with dementia. It is the preference of many people with dementia to remain living at home until death, with the appropriate care. To develop a successful model for dementia palliative care in the community, it is essential to assimilate the perspectives and experiences of those affected. The guiding research question for this study was: What are people with dementia and family carers' views on a model for dementia palliative care?., Methods: Focus groups ( n = 3) were conducted with bereaved or current family carers ( n = 11), and people with dementia ( n = 2). Discussions centred around a proposed model of dementia palliative care. These were transcribed and analysed using thematic analysis., Results: Three main themes were identified: living and dying well with dementia; reducing carer burden to fulfil the wish for home care; and lack of faith in the healthcare system. One statement which summarised the analysis was: "Dementia palliative care is a dream, but not a reality." This reflected participants' repeated "wish" for this "ideal" model of care, but simultaneous scepticism regarding its implementation, based on their prior experiences of healthcare services., Conclusion: All participants were welcoming of the proposed model for dementia palliative care and were generally positive about palliative care as a concept relating to dementia. There was consensus that the model would allow people to live and die well with dementia, and reducing the carer burden would fulfil the wish to remain at home. However systemic changes in the healthcare system will be needed to facilitate a truly person-centred, holistic, individualised and flexible model of care., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Background: As an alternative to traditional open reduction internal fixation of ankle fragility fractures, primary retrograde tibiotalocalcaneal (TTC) nailing has been investigated as a treatment option. These results suggest that this treatment is an acceptable alternative treatment option for these injuries. There are still questions about the need for formal joint preparation at the subtalar or tibiotalar joint when performing primary TTC nailing for fragility fractures., Methods: In this study, we retrospectively evaluated 32 patients treated with primary retrograde TTC nail without subtalar or tibiotalar joint preparation for a mean of 2.4 years postoperatively. We specifically reviewed the charts for nail breakages at either joint, patients developing subtalar or tibiotalar joint pathology requiring additional treatment, including return to the operating room for formal joint preparation., Results: Fracture union occurred in 100% of patients. There were 3 cases (10.0%) of hardware failure, and 2 of these cases were asymptomatic and did not require any treatment. One patient (3.3%) developed hardware failure with nail breakage at the subtalar joint. This patient developed progressive pain and symptoms requiring revision surgery with formal arthrodesis of the subtalar and tibiotalar joint., Conclusions: This study shows that retrograde hindfoot nailing without formal subtalar or tibiotalar joint preparation is an acceptable potential treatment option in ankle fragility fractures. Mid-term follow-up demonstrates favorable outcomes without the need for formal joint preparation in this high-risk population. Comparative studies with higher patient numbers and long-term follow-up are needed to confirm the results of this study. Levels of Evidence: Level IV., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Background: Overhead throwing in baseball and softball athletes induces shoulder adaptations theorized to increase risk of shoulder musculoskeletal injury (MSI) and/or pain due to range of motion (ROM) deficits., Hypothesis: Shoulder ROM adaptations are associated with a higher risk for developing shoulder MSI and pain., Study Design: Prospective cohort study., Level of Evidence: Level 3., Methods: A total of 60 National Collegiate Athletic Association Division I athletes cleared for full athletic participation and free from upper extremity MSI in the last 4 weeks (age, 19.0 ± 1.2 years; weight, 82.1 ± 13.7 kg; height, 178.6 ± 11.2 cm; softball, n = 23; baseball, n = 37). Passive glenohumeral internal rotation (IR), external rotation (ER), and horizontal adduction (HA) ROM were measured with the scapula stabilized and used to categorize participants with/without external rotation gain (ERG), external rotation insufficiency (ERI), glenohumeral internal rotation deficit (GIRD), pathological GIRD, and posterior shoulder tightness (PST) before the competitive season. Groups were then compared to assess the incidence of shoulder MSI prospectively and prevalence of shoulder pain at the initial evaluation., Results: Baseball and softball athletes demonstrated significantly less IR ROM in the dominant shoulder (50.6° ± 9.4°) compared with the nondominant shoulder (59.1° ± 8.6°; P < 0.01) and significantly more ER ROM (dominant, 104.6° ± 12.1°; nondominant, 97.7° ± 12.0°; P < 0.01). Incidence of shoulder MSI was 15% but was not significantly related to any shoulder adaptations. No significant relationship was found between prevalence of pain and any shoulder adaptations in the 27% of athletes with pain., Conclusion: Increased ER and decreased IR ROM adaptations in intercollegiate overhead throwing athletes do not appear to be correlated to risk of shoulder MSI or pain., Clinical Relevance: The findings of this level 3 prospective study provide clinicians working with overhead athletes information regarding shoulder MSI risk and pain. It is recommended that clinicians should not use ROM adaptations exclusively to determine increased risk of shoulder MSI., Competing Interests: The authors report no potential conflicts of interest in the development and publication of this article

- Abstract
Background: First metatarsophalangeal joint arthrodesis with isolated dorsal plating without a lag screw and without a compressive mechanism incorporated into the plate is not well studied. Although surface area for bony fusion is increased, there is concern for lower fusion rates and progressive loss of sagittal plane positioning. We present fusion rates and progressive sagittal plane deviation with isolated dorsal plate fixation., Methods: A retrospective review was performed of 41 patients (43 feet) who underwent first metatarsophalangeal joint arthrodesis with isolated dorsal plate fixation. Patients were excluded if another form of fixation was used, if there was a compressive feature to the dorsal plate, or if a lag screw was used. Preoperative, immediate postoperative, and final postoperative radiographs were reviewed to assess radiographic alignment and fusion about the first metatarsophalangeal joint. Specific attention was placed on hallux dorsiflexion in relation to the first metatarsal. Statistical significance was set at P ≤ .05 a priori., Results: Patients were followed for an average of 55.7 weeks. Overall union rate was 97.62%. The average time to union was 42.55 days. Reoperation rate was 4.65%, with one patient requiring revisional arthrodesis with a lag screw construct. Hallux abduction and first-second intermetatarsal angle correction reached significance (P < .00001). Hallux dorsiflexion increased by 1.05° between initial postoperative and final postoperative radiographs (P = .542)., Conclusions: Although fusion rates and progressive loss of sagittal plane position have been concerns for first metatarsophalangeal joint arthrodesis with an isolated dorsal plate construct, these results suggest this to be a stable construct without loss of positioning over time.

- Abstract
Context: Diabetic ketoacidosis (DKA) is an endocrine emergency that can occur in people with diabetes. Its incidence is estimated to be 220,340 hospital admissions each year. Treatment algorithms include fluid resuscitation, intravenous (IV) insulin infusion, and scheduled electrolyte and glucose monitoring. The misdiagnosis of DKA in the setting of hyperglycemic emergencies results in overtreatment and unnecessary increases in healthcare utilization and costs., Objectives: The aims of this study were to determine how often DKA is overdiagnosed in the context of other acute hyperglycemic emergencies, to describe the baseline characteristics of patients, to determine the hospital treatments for DKA, and to identify the frequency of endocrinology or diabetology consultation in the hospital setting., Methods: A retrospective chart review was conducted utilizing charts from three different hospitals within a hospital system. Charts were identified utilizing ICD-10 codes for admissions to the hospital for DKA. If the patient was over 18 and had one of the diagnostic codes of interest, the chart was reviewed for further details regarding the criteria for DKA diagnosis as well as admission and treatment details., Results: A total of 520 hospital admissions were included for review. DKA was incorrectly diagnosed in 28.4 % of the hospital admissions reviewed, based on a review of the labs and DKA diagnostic criteria. Most patients were admitted to the intensive care unit (ICU) and treated with IV insulin infusion (n=288). Consultation of endocrinology or diabetology occurred in 40.2 % (n=209) of all hospital admissions, and 128 of those consults occurred in ICU admissions. The diagnosis of DKA was incorrect in 92 of the patients admitted to the medical surgical unit (MSU) and in 49 of patients admitted to the ICU., Conclusions: Almost one third of hospital admissions for hyperglycemic emergencies were misdiagnosed and managed as DKA. DKA diagnostic criteria are specific; however, other diagnoses like hyperosmolar hyperglycemic syndrome (HHS), hyperglycemia, and euglycemic DKA can make an accurate diagnosis more complicated. Education directed at improving the diagnostic accuracy of DKA among healthcare providers is needed to improve diagnostic accuracy, ensure the appropriate use of hospital resources, and potentially reduce costs to the healthcare system., (© 2023 the author(s), published by De Gruyter, Berlin/Boston.)

- Abstract
Background: Increased length of stay after total joint arthroplasty has been shown to be a risk factor for peri-operative complications. The purpose of this study was to determine if Medicaid insurance would be a risk factor for increased length of stay after total joint arthroplasty., Methods: We retrospectively reviewed a single surgeon's practice of 428 total hip and total knee arthroplasties who had insurance status of Medicaid, Medicare, Private or none. After exclusion criteria there were 400 patients. Patients with insurance status of Medicaid, Medicare or Private were then compared based on length of stay ≤ 2 days and length of stay > 2 days and then further analyzed using demographic, operative data, and total length of stay., Results: Medicaid patients had an increased length of stay compared to patients with Medicare or Private insurance [1.98 days versus 1.73 days, p = .037, 95% confidence intervals (1.78-2.18) and (1.61-1.85), respectively]. The greatest predictor of a less than two-night stay post-operatively was private insurance status (p = 0.001). Medicaid patients had a higher incidence of prescribed narcotic use pre-operatively (p = 0.013). Although not significant, a trend was noted in the Medicaid population with higher incidence of smoking (p = 0.094) and illicit drug abuse (p = 0.099) pre-operatively in this sample subset., Conclusions: Patients with Medicaid insurance undergoing total joint arthroplasty have increased length of stay compared to patients with Medicare or Private insurance and have higher incidence of pre-operative narcotic use., (© 2022.

- Abstract
Determining what factors influence the distribution and abundance of wildlife populations is crucial for implementing effective conservation and management actions. Yet, for species with dynamic seasonal, sex-, and age-specific spatial ecology, like the diamondback terrapin ( Malaclemys terrapin ; DBT), doing so can be challenging. Moreover, environmental factors that influence the distribution and abundance of DBT in their northernmost range have not been quantitatively characterized. We investigated proximity to nesting habitat as one potential driver of spatiotemporal variation in abundance in a three-step analytical approach. First, we used a scale selection resource selection function (RSF) approach based on landcover data from the National Landcover Database (NLCD) to identify the scale at which DBT are selecting for (or avoiding) landcover types to nest. Next, we used RSF to predict areas of suitable nesting habitat and created an index of nest suitability (NSI). Finally, analyzing visual count data using a generalized linear mixed model (GLMM), we investigate spatiotemporal drivers of relative abundance, with a specific focus on whether similar factors affect offshore abundance and onshore nest site selection. We found the scale of selection for developed and saltmarsh land use classes to be 550 and 600 m and open water land use classes to be 100. Selection was positive for nesting areas proximal to saltmarsh habitat and negative for developed and open water. Expected relative abundance was best explained by the interaction between NSI and day of season, where expected relative abundance was greater within high NSI areas during the nesting season (2.20 individuals, CI: 1.19-3.93) compared to areas of low NSI (1.84 individuals, CI: 1.10-3.10). Our results provide evidence that inferred spatial patterns of suitable nesting habitats explain spatiotemporal patterns of terrapin movement and abundance., (© 2023 The Authors.

- Abstract
Background: Resident-run clinics provide autonomy and skill development for resident physicians. Many residency programs have such a clinic. No study has been performed investigating the effectiveness of these clinics in podiatric medical residency training. The purpose of this study was to gauge the resident physician-perceived benefit of such a clinic., Methods: A survey examining aspects of a resident-run clinic and resident clinical performance was distributed to all Doctor of Podiatric Medicine residency programs recognized by the Council on Podiatric Medical Education. To be included, a program must have had a contact e-mail listed in the Central Application Service for Podiatric Residencies residency contact directory; 208 residency programs met the criteria. Statistical analysis was performed using independent-samples t tests or Mann-Whitney U tests and χ2 tests. Significance was set a priori at P < .05., Results: Of 97 residents included, 58 (59.79%) had a resident-run clinic. Of those, 89.66% of residents stated they liked having such a clinic, and 53.85% of those without a resident-run clinic stated they would like to have one. No statistically significant differences were noted between groups in how many patients each resident felt they could manage per hour or regarding their level of confidence in the following clinical scenarios: billing, coding, writing a note, placing orders, conversing with a patient, working with staff, diagnosing and treating basic pathology, and diagnosing and treating unique pathology., Conclusions: Resident-run clinics provide autonomy and skill development for podiatric medical residents. This preliminary study found there was no difference in resident-perceived benefit of such a clinic. Further research is needed to understand the utility of a resident-run clinic in podiatric medical residency training.

- Abstract
Background: Recent evidence has demonstrated that athletes are at greater risk for a lower extremity injury following a return-to-sport (RTS) after sport-related concussion (SRC). The reason for this is not completely clear, but it has been hypothesized that persistent deficits in neurocognitive factors may be a contributing factor., Hypothesis/purpose: This study assessed simple reaction time, processing speed, attention, and concentration in a group of athletes, post-concussion upon clearance for RTS for potential deficits that may result in slower reaction time, processing speed, attention, and concentration. The researchers hypothesized that the concussion group would demonstrate worse scores on both assessments compared to a sex-, age-, and sport-matched cohort., Study Design: Case-controlled study., Methods: Twelve participants who had suffered a SRC and eight healthy individuals who were matched to the concussed group by age, sex, and sport were evaluated. Those with a concussion had been cleared for RTS by a licensed healthcare provider. Each participant underwent neurocognitive tests that included a simple reaction time test (SRT) and the King-Devick Test (K-D). Independent t-tests were performed to compare the groups with significance set a priori at p<0.05., Results: There was a significant difference (p =0.024) between groups for SRT with the concussed group demonstrating a better SRT than the control group. There were no significant differences (p =0.939) between the groups for the K-D., Conclusion: With no significant differences between groups in the K-D assessment and, surprisingly, the concussed group having a better SRT compared to the healthy group, our hypothesis was not supported., Clinical Relevance: These specific measures, compounded with extensive post-concussion time lapse until RTS clearance, may have limited capacity in revealing potential persistent deficits in relevant neurocognitive characteristics., Level of Evidence: Level of Evidence 3., Competing Interests: The authors report no conflicts of interest.

- Abstract
To evaluate the hypothesis that patients with a history of intravenous drug misuse (IVDM) initiated on weight-based heparin infusions require higher than expected infusion rates to achieve therapeutic activated partial thromboplastin time (aPTT). This study is a multicenter, retrospective chart review of patients with a history of IVDM who were admitted to an acute care site between 10/1/2015 and 9/30/2020 and treated with continuous heparin infusions. Patients were identified using ICD9 and ICD10 codes and included if they had a documented history of IVDM within the past six months. Variables of particular interest included: median heparin infusion rates to maintain therapeutic aPTT, average time to reach therapeutic aPTT, and International Society of Thrombosis and Haemostasis Criteria for moderate to severe bleeding. Of the 41 patients who met the inclusion and exclusion criteria, 39 achieved therapeutic aPTT while on a weight-based heparin infusion. All heparin infusions were initiated at a rate of 18 units/kg/hr then titrated per institutional heparin infusion protocols. The mean time to therapeutic aPTT was 38.48 h ± 26.4 h with a mean infusion rate of 27.64 ± 7.14 units/kg/hr. To maintain therapeutic anticoagulation, infusion rates 150% higher than the initial rate were required. Of the 39 patients who achieved therapeutic aPTT, 85% (33) met criteria for heparin resistance, defined as greater than 35,000 units of heparin daily. No statistical significance could be derived from this retrospective chart review as therapeutic heparin rates were evaluated in comparison to initial infusion rate, rather than a control group. The findings in this study demonstrate a possible clinical association of the reduced antithrombin activity previously described in opiate misusers. To efficiently achieve therapeutic anticoagulation, it may be appropriate to consider use of heparin antiXa monitoring in place of aPTT or utilization of increased initial heparin infusion rates., (© 2021.

- Abstract
Context: Strength ratios are important because imbalances in opposing muscle groups can cause articular instability and subsequently increase the risk of musculoskeletal injury (MSKI). Therefore, the purpose of this study was to evaluate the association between lower extremity (LE) musculoskeletal isometric strength ratios and the history of LE MSKI., Participants: One hundred eighty-two NCAA Division 1 soccer, football, volleyball, and basketball athletes., Interventions: All isometric strength assessments were measured bilaterally using a handheld dynamometer. Strength assessments included: ankle inversion/eversion, ankle dorsiflexion/plantarflexion, knee flexion/extension, hip abduction/adduction, and hip external/internal rotation. LE MSKI history was collected through self-report; a report of the LE MSKI sustained in the one year prior to testing were collected., Results: The hip external/internal rotation ratio was statistically significant for side to side differences in the non-injured (NINJ) group (p = 0.001). The dominant leg of the NINJ group had a mean external/internal rotation ratio of 1.109 ± 0.221, and the non-dominant leg had a mean ratio of 1.177 ± 0.208., Conclusions: There were no statistically significant differences between the injured (INJ) and NINJ groups. This could indicate that injury history does not play a role in current strength ratios and could suggest that the athletes in the INJ group are performing successful rehabilitation for their injuries., Competing Interests: Declaration of competing interest None Declared., (Copyright © 2022 Elsevier Ltd.

- Abstract
The period when medical students begin residency in teaching hospitals throughout the United States heralds a period known in the medical community as the "July Effect." Though several sentinel studies associated this timeframe with an increase in medical errors, residencies since demystified this phenomenon within their respective specialty. This study aims to evaluate the presence of the July Effect in a podiatric medicine and surgery residency program. A retrospective chart review was conducted, comparing patient demographics and surgical outcomes including length of stay, operative time and readmission rate between the first (July, August, September) and fourth (April, May June) quarters of the academic year from 2014-2019. A total of 206 patients met the inclusion criteria, where 99 received care in the first, resident-naïve, quarter and 107 received care in the fourth, resident-experienced, quarter. No difference in patient demographics including sex, body mass index, or comorbidity index was appreciated between both quarters (p<0.05). Those patients who underwent soft tissue and bone debridements, digital, forefoot, midfoot and rearfoot amputations experienced no statistically significant difference in length of stay, operative time, or readmission rate between both quarters (p<0.05). The results of this study did not support the presence of the July Effect in our foot and ankle surgery residency. Future studies can further explore this phenomenon by examining patients admitted following traumatic injury or elective procedures. Moreover, this study shows the curriculum employed at our program provides sufficient support, guidance, and resources to limit errors attributed to the July Effect., (Copyright © 2021 the American College of Foot and Ankle Surgeons.

- Abstract
Background: Risk factors for different sports injuries vary between sexes. Deficits in postural stability have been associated with several lower extremity injuries. The purpose of this study was to examine the differences in static postural stability between male and female intercollegiate athletes with and without visual information. # HypothesisThere will be no difference in visual reliance between sexes during static postural stability., Study Design: Cross-sectional Study., Methods: Static postural stability was assessed during a single session for football, soccer, basketball, and volleyball intercollegiate athletes (males, n=135, females, n=51) under eyes open (EO) and eyes closed (EC) conditions via performance of single limb stance on a force plate. Ground reaction force component data in all directions were quantified as a unitless composite score (COMP) where lower values indicated better postural stability. The absolute change and percentage change between EO and EC conditions were calculated for each sex. Two-sample Kolmogorov-Smirnov tests were used to compare differences between sexes., Results: Males had greater EO COMP (males=7.77±3.40; females=6.48±4.61; p=0.038; Cohen's d=0.343) and EC COMP (males=19.43±8.91; females 14.66±6.65; p=0.001; Cohen's d=0.571) than females. A significant difference in absolute change from EO to EC was observed between sexes (males=-11.65±7.05; females=-8.18±5.61; p=0.01, Cohen's d=-0.520) indicating that males had a greater change between conditions for the worse. There was no significant difference in percent change from EO to EC between sexes (males=159.2±90.7; females=156.7±109.2; p=0.39; Cohen's d=0.026)., Conclusions: The observed differences between males and females in EO COMP, EC COMP, and absolute difference in COMP indicate that there is some factor that causes a difference in static postural stability between sexes. No difference in percent change between groups indicates that the difference in static postural stability between sexes may not be due to visual reliance. Female athletes may inherently have better postural stability than males, but both sexes were able to compensate for the loss of visual input., Level of Evidence: 3., Competing Interests: We have no conflicts of interest to disclose.

- Abstract
Injury rates in student athletes are high and often unpredictable. Injury risk factors are not agreed upon and often not validated. Here, we present a random-forest machine learning methodology for identifying the most significant injury risk factors and develop a model of lower extremity musculoskeletal injury risk in student athletes with physical performance metrics spanning joint strength measured with force transducers, postural stability measured using a force plate, and flexibility, measured with a goniometer, combined with previous injury metrics and athlete demographics. We tested our model in a population of 122 student athletes with performance metrics for the lower extremity musculoskeletal system and achieved an injury risk accuracy of 79% and identified significant injury risk factors, that could be used to increase accuracy of injury risk assessments, implement timely interventions, and decrease the number of career-ending or chronic injuries among student athletes., (Copyright © 2020 Henriquez, Sumner, Faherty, Sell and Bent.)

- Abstract
Rupture of the anterior cruciate ligament (ACL) remains extremely common, with over 250,000 injuries annually. Currently, clinical tests have poor utility to accurately screen for ACL injury risk in athletes. In this study, the position of a knee marker was tracked in 2-dimensional planes to predict biomechanical variables associated with ACL injury risk. Three-dimensional kinematics and ground reaction forces were collected during bilateral, single-leg stop-jump tasks for 44 healthy male military personnel. Knee marker position data were extracted to construct 2-dimensional 95% prediction ellipses in each anatomical plane. Knee marker variables included: ellipse areas, major/minor axes lengths, orientation of ellipse axes, absolute ranges of knee position, and medial knee collapse. These variables were then used as predictor variables in stepwise multiple linear regression analyses for 7 biomechanical variables associated with ACL injury risk. Knee flexion excursion, normalized peak vertical ground reaction forces, and knee flexion angle at initial contact were the response variables that generated the highest adjusted R2 values: .71, .37, and .31, respectively. The results of this study provide initial support for the hypothesis that tracking a single marker during 2-dimensional analysis can accurately reflect the information gathered from 3-dimensional motion analysis during a task assessing knee joint stability.

- Abstract
Context: Concussions are consequence of sports participation. Recent reports indicate there is an increased risk of lower-extremity musculoskeletal injury when returning to sport after concussion suggesting that achieving "normal" balance may not fully indicate the athlete is ready for competition. The increased risk of injury may indicate the need to refine a screening tool for clearance., Objective: Assess the between-session reliability and the effects of adding a cognitive task to static and dynamic postural stability testing in a healthy population., Setting: Clinical laboratory., Participants: Twelve healthy subjects (6 women; age 22.3 [2.9] y, height 174.4 [7.5] cm, weight 70.1 [12.7] kg) participated in this study., Design: Subjects underwent static and dynamic postural stability testing with and without the addition of a cognitive task (Stroop test). Test battery was repeated 10 days later. Dynamic postural stability testing consisted of a forward jump over a hurdle with a 1-legged landing. A stability index was calculated. Static postural stability was also assessed with and without the cognitive task during single-leg balance. Variability of each ground reaction force component was averaged., Main Outcome Measures: Interclass correlation coefficients (ICC2,1) were computed to determine the reliability. Standard error of measure, mean standard error, mean detectable change, and 95% confidence interval were all calculated., Results: Mean differences between sessions were low, with the majority of variables having moderate to excellent reliability (static .583-.877, dynamic .581-.939). The addition of the dual task did not have any significant effect on reliability of the task; however, generally, the ICC values improved (eyes open .583-.770, dual task .741-.808)., Conclusions: The addition of a cognitive load to postural stability assessments had moderate to excellent reliability in a healthy population. These results provide initial evidence on the feasibility of dual-task postural stability testing when examining risk of lower-extremity musculoskeletal injury following return to sport in a concussed population.

- Abstract
Kemp's ridley sea turtles were on the verge of extinction in the 1960s. While these sea turtles have slowly recovered, they are still critically endangered. In the last few years, the number of strandings on the beaches of Cape Cod, Massachusetts has increased by nearly an order of magnitude relative to preceding decades. This study uses a combination of ocean observations and a well-respected ocean model to investigate the causes and transport of cold-stunned sea turtles in Cape Cod Bay. After validating the model using satellite-tracked drifters and local temperature moorings, ocean currents were examined in Cape Cod Bay in an attempt to explain stranding locations as observed by volunteers and, for some years, backtracking was conducted to examine the potential source regions. The general finding of this study is that sub 10.5°C water temperatures in combination with persistently strong wind stress (>0.4 Pa), results in increased strandings along particular sections of the coast and are dependent on the wind direction. However, it is still uncertain where in the water column the majority of cold-stunned turtles reside and, if many of them are on the surface, considerable work will need to be done to incorporate the direct effects of wind and waves on the advective processes., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Objectives: In National Collegiate Athletic Association Division I swimmers, we examined the differences in thoracic spine rotation in swimmers with and without scapular dyskinesis and the relationship between thoracic spine rotation and shoulder pain/dysfunction according to the Kerlan-Jobe Orthopaedic Clinic (KJOC) score., Design: Cross-sectional., Setting: Laboratory-based., Participants: 34 NCAA Division I swimmers (13 males, 21 females)., Main Outcome Measures: Self-reported upper extremity function and pain assessed with the KJOC questionnaire, thoracic spine range of motion, presence of scapular dyskinesis., Results: Dyskinesis was present in 15 of 34 (44%) subjects. Thoracic rotation averaged 136.7° and KJOC averaged 87.7 with no differences between swimmers with or without dyskinesis. We observed no correlation between KJOC-identified shoulder pain/dysfunction and thoracic rotation., Conclusions: In our cohort of NCAA Division 1 swimmers, no differences were found between swimmers with or without scapular dyskinesis and extent of thoracic rotation. We found no correlation between thoracic rotation and the amount of self-reported pain and dysfunction experienced in the upper extremity. The presence of scapular dyskinesis in nearly half of our subjects indicates that swimmers need to be assessed for this abnormality. If observed, rehabilitation should address the dyskinesis and improve thoracic rotation in an attempt to alleviate further upper extremity pain and dysfunction., (Copyright © 2019 Elsevier Ltd.

- Abstract
Since the 1970s, the magnitude of turtle cold-stun strandings have increased dramatically within the northwestern Atlantic. Here, we examine oceanic, atmospheric, and biological factors that may affect the increasing trend of cold-stunned Kemp's ridleys in Cape Cod Bay, Massachusetts, United States of America. Using machine learning and Bayesian inference modeling techniques, we demonstrate higher cold-stunning years occur when the Gulf of Maine has warmer sea surface temperatures in late October through early November. Surprisingly, hatchling numbers in Mexico, a proxy for population abundance, was not identified as an important factor. Further, using our Bayesian count model and forecasted sea surface temperature projections, we predict more than 2,300 Kemp's ridley turtles may cold-stun annually by 2031 as sea surface temperatures continue to increase within the Gulf of Maine. We suggest warmer sea surface temperatures may have modified the northerly distribution of Kemp's ridleys and act as an ecological bridge between the Gulf Stream and nearshore waters. While cold-stunning may currently account for a minor proportion of juvenile mortality, we recommend continuing efforts to rehabilitate cold-stunned individuals to maintain population resiliency for this critically endangered species in the face of a changing climate and continuing anthropogenic threats., Competing Interests: The authors have declared that no competing interests exist.
