Oncologic Staging Computed Tomography with IV Contrast Has Similar Efficacy to Dedicated Computed Tomography Angiography for Preoperative DIEP Flap Planning.

Background: Due to variations in perforator vasculature, deep inferior epigastric artery perforator (DIEP) flap preoperative imaging can minimize operative time required to locate the most suitable perforators. Dedicated computed tomography angiography (CTA) has been the gold standard; however, many patients have already undergone a staging computed tomography (CT) per oncologic workup. The benefits from CTA may also be realized with a staging CT or CT with IV contrast. Methods: Ten patients who underwent DIEP flap reconstruction with staging CT and CTA within 3 years of one another were included in this study. Reviewers evaluated axial views of both imaging modalities separately to identify each visible perforator in reference to the pubic symphysis from the xiphoid to the pubic symphysis. An intraclass correlation coefficient (ICC) was used to determine agreement in location of perforators between the two imaging studies. Statistical analysis was performed using an ICC and Wilcoxon signed rank-tests. Results: The identified perforators within the patient cohort had an excellent correlation between their location on CT and CTA based upon ICC. The mean number of perforators identified in the CT group was 15.3 (SD 4.9) and in the CTA group was 18.8 (SD 6.4), which was not statistically different (P = 0.247). Conclusions: CT has similar efficacy in identifying number of perforators and perforator location to dedicated CTA for preoperative planning in DIEP flaps. This has the potential for decreased patient contrast and ionizing radiation exposure as well as improved patient and healthcare resource utilization.

A Narrative Review of Non-Pharmacological Strategies for Managing Sarcopenia in Older Adults with Cardiovascular and Metabolic Diseases.

This narrative review examines the mechanisms underlying the development of cardiovascular disease (CVD) and metabolic diseases (MDs), along with their association with sarcopenia. Furthermore, non-pharmacological interventions to address sarcopenia in patients with these conditions are suggested. The significance of combined training in managing metabolic disease and secondary sarcopenia in type II diabetes mellitus is emphasized. Additionally, the potential benefits of resistance and aerobic training are explored. This review emphasises the role of nutrition in addressing sarcopenia in patients with CVD or MDs, focusing on strategies such as optimising protein intake, promoting plant-based protein sources, incorporating antioxidant-rich foods and omega-3 fatty acids and ensuring sufficient vitamin D levels. Moreover, the potential benefits of targeting gut microbiota through probiotics and prebiotic fibres in sarcopenic individuals are considered. Multidisciplinary approaches that integrate behavioural science are explored to enhance the uptake and sustainability of behaviour-based sarcopenia interventions. Future research should prioritise high-quality randomized controlled trials to refine exercise and nutritional interventions and investigate the incorporation of behavioural science into routine practices. Ultimately, a comprehensive and multifaceted approach is essential to improve health outcomes, well-being and quality of life in older adults with sarcopenia and coexisting cardiovascular and metabolic diseases.

Managing Ulnar Nerve Subluxation With a Medial Intermuscular Septum Sling.

BACKGROUND: Cubital tunnel syndrome (CuTS) is a lifestyle-altering peripheral neuropathy lacking a consensus for optimal surgical management. We describe creation of a fascial "V-sling" without ulnar nerve transposition, which is associated with increased surgical morbidity compared with decompression. The purpose of this study is to evaluate a novel technique with effective ulnar nerve decompression and subluxation prevention by creating a fascial sling in patients with CuTS and ulnar nerve subluxation. METHODS: We reviewed records of 39 elbows in 35 patients who underwent in situ ulnar nerve decompression and creation of a fascial sling in a "V" configuration to stabilize the nerve in its native position. We examined patient demographics, Single Assessment Numeric Evaluation (SANE) scores, Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) scores, and patient outcomes. Chi-square and student's t test were used for all analysis. RESULTS: A total of 37 extremities in 33 patients undergoing nerve decompression had nerve subluxation confirmed intraoperatively. There was a statistically significant change in preoperative and postoperative SANE scores of 64.5 and 82.3, respectively. Mean QuickDASH scores decreased significantly from 49.3 preoperative to 10.8 postoperative. The long-term QuickDASH scores obtained at mean of 564 days were maintained at 10.76. CONCLUSIONS: This study describes a novel technique for treating CuTS by achieving in situ nerve decompression and addressing ulnar nerve subluxation with creation of an intermuscular septal sling. The technique improved functional outcomes and provided symptomatic relief, while avoiding risks commonly associated with nerve transposition.

Physician collections are 71% less for early onset scoliosis casting than for growing rod instrumentation: A retrospective cohort study.

Growing rod (GR) instrumentation and the elongation, derotation, and flexion (EDF) casting technique are 2 alternatives for the treatment of early-onset scoliosis. Our purpose was to investigate the cost of these treatment options. This was a retrospective cohort study of patients with early-onset scoliosis treated at 2 institutions from 2007 to 2014 with either GR instrumentation or EDF casting. Patients with <2 years of follow-up were excluded. Physician and hospital charges and collections, total procedures, and procedure times until final follow-up or time of fusion were compared. Nineteen patients met the inclusion criteria; 8 in the GR group and 11 in the EDF casting group. There were no significant differences between the groups in age (P = .23), public versus private insurance (P = 1.0), or major curve (P = .21) at the initiation of treatment. Excluding final fusion, the EDF casting patients had an average of 2.1 (range: 0.7-6.6) procedures/year while the GR patients had an average of 1.5 (range: 0.8-2.7) procedures/year. The average procedure time for the EDF group was 104.2 minutes; the average procedure time for the GR group, excluding the index procedure, was 62.40 minutes (P = .001). Physician charges were 85% less for the EDF group (EDF= $1892.75, GR= $12,354.53, P < .001). Physician collections were 71% less for the EDF group (EDF= $731.10, GR= $2554.88, P = .001). Hospital charges and collections were similar between the groups (P = .82, P = .42). Physician charges for casting were approximately 18% of that of GRs. Compared to GRs, physician collections were 71% less for EDF casting patients per year.

Modernizing Our Understanding of Total Hip Arthroplasty in the Pediatric and Young Adult Patient: A Single-center Experience.

INTRODUCTION: Pediatric hip disorders represent a broad range of pathology and remain a significant source of morbidity for children and young adults. Surgical intervention is often required for joint preservation, but when salvage is not possible, joint replacement may be indicated to eliminate pain and preserve function. Although there have been significant updates in the management of both pediatric hip disease and the field of total hip arthroplasty (THA), there is a paucity of literature reflecting advancements in the area of pediatric and young adult (PYA) arthroplasty. No study has investigated the impact of approach on outcomes after PYA THA. The purpose of this study is to describe the indications, techniques, and early outcomes of THA in the PYA population in a modern practice setting. METHODS: We performed a retrospective descriptive analysis of all patients undergoing primary THA performed at a tertiary care children's hospital from 2004 to 2019. Ninety-three hips in 76 patients were evaluated. Demographics, intraoperative variables, postoperative pain and function ratings, and complication and revision rates were collected. RESULTS: Eighty-five hips in 69 patients were included. Patients were aged 12 to 23 years old, with males and females represented equally (33 vs. 36, respectively). The most common cause of hip pain was avascular necrosis (AVN, 56/85, 66%), most commonly due to slipped capital femoral epiphysis (13/56, 23%) idiopathic AVN (12/56, 21%), and chemotherapy (12/56, 21%). Half of all hips had been previously operated before THA (43/85). Thirty-six procedures were performed via the posterolateral approach (36/85, 42%), 33 were performed via direct anterior approach (33/85, 39%), and 16 were performed via the lateral approach (LAT, 16/85, 19%). At final follow-up, 98% (83/85) of patients had complete resolution of pain, 82% (70/85) had no notable limp, and 95% (81/85) had returned to all activities. There were 6 complications and 1 early revision. Average Hip disability and Osteoarthritis Outcomes Score for Joint Replacement scores increased by 37 points from 56 to 93. The overall revision-free survival rate for PYA THA was 98.8% (at average 19-mo follow-up). CONCLUSIONS: Modern PYA THA is dissimilar in indications and surgical techniques to historic cohorts, and conclusions from prior studies should not be generalized to modern practice. In our practice, PYA patients most commonly carry a diagnosis of AVN, and THA can be performed with modern cementless fixation with large cup and head sizes and ceramic-on-cross-linked polyethylene bearings utilizing any approach. Further study is required to better characterize middle-term and long-term results and patient-reported outcomes. LEVEL OF EVIDENCE: Therapeutic Level IV-retrospective case series.

The Health Education and Training (HEAT) Corps: A Medical-Community Collaboration Response during the COVID-19 Pandemic.

With the declaration of the COVID-19 pandemic by the World Health Organization in March 2020, many elements of society were faced with attempting to assimilate public health recommendations for infectious control. Vital social organizations had to balance delivering their social services while attempting to stay up to date with COVID-19 information and comply with evolving regulations. In the realm of schools and school systems, guidance on how to best adapt to COVID-19 was often limited. School officials and staff had to assist with multiple public health crises as a consequence of the pandemic, from the pandemic's transmission prevention strategies (e.g., face masks and physical distancing) to the recognition that students would have personal tragedies related to COVID-19. In this review, we highlight the process and feasibility of implementing an international COVID-19 school-based initiative over two years of the pandemic, the Health Education and Training (HEAT) Corps program.

Implementation of a Multimodal Knowledge-Exchange Platform to Provide Trauma Critical Care Education During the Ongoing Conflict in Ukraine.

Importance: The conflict in Ukraine has forced civilian hospitals with limited trauma and battlefield medicine experience to care for casualties of war, placing significant strain on the health care system. Using the Checklist for Early Recognition and Treatment of Acute Illness and Injury (CERTAIN) program, a multimodal trauma critical care knowledge-exchange platform was created for clinicians practicing in these institutions. Objectives: To describe the development and implementation of the CERTAIN for Ukraine program and to evaluate the reach of this intervention, together with participant engagement and satisfaction. Design, Setting, and Participants: This quality improvement study included clinicians caring for critically ill patients during the ongoing Ukrainian conflict who were part of a community developed using a messaging app. The program was implemented by a group of international trauma and critical care experts in collaboration with critical care leaders from the Shupyk National Healthcare University in Kyiv, Ukraine. This study evaluates data collected from the CERTAIN for Ukraine program from its launch on April 9, 2022, to August 31, 2022. Interventions: The initiative comprised a longitudinal series of interactive tele-education sessions, a webpage containing the CERTAIN approach and current trauma critical care guidelines translated into Ukrainian and Russian, and a private messaging chat for asynchronous discussion. Main Outcomes and Measures: Participant engagement and satisfaction were tracked using multimedia analytics and a post-session survey. Results: Since program launch, 838 participants have joined the messaging group, and 6 tele-education sessions have been delivered, with 1835 total views. The CERTAIN website has had 3527 visits, mainly from Ukraine (1378 [39%]) and the United States (1060 [30%]). Of the 74 completed postsession surveys, 65 respondents (88%) rated the course content excellent or very good, and 73 (99%) recommended it to others. Conclusions and Relevance: The findings of this quality improvement study indicate that, using widely available and low-cost platforms, knowledge was shared rapidly and efficiently to a large community of clinicians practicing in a wartime environment with broad-based engagement and a high level of learner satisfaction.

Intracranial Hypertension Associated With Testosterone Therapy In Female-To-Male Transgender Patients: A Case Report And Literature Review.

We highlight a case of intracranial hypertension secondary to exogenous testosterone in a female-to-male transgender patient and present a systematic review of similar cases. Our review identified 19 female-to-male transgender individuals with intracranial hypertension. The mean age was 24.2 years and most common presenting symptom was headache (78.9% of patients). The most frequently associated ocular symptoms were transient visual obscurations (42.1%) and blurred vision (21.1%). Onset of symptoms occurred concurrently with exogenous testosterone therapy in 89.5% of the patients. The most common treatments were acetazolamide (89.5%), topiramate (31.6%), and alteration in hormone regimen (21.1%); four cases required surgery. These findings aid clinicians treating intracranial hypertension in patients undergoing gender affirmation therapy in a conscientious, patient-centered manner.

Immediate Deep Inferior Epigastric Perforator Flap Reconstruction of a Giant Phyllodes Tumor.

We present a case of a giant phyllodes tumor (PT) requiring simple mastectomy with en bloc pectoralis major resection and immediate deep inferior epigastric perforator (DIEP) flap reconstruction. This patient presented with a four-year history of an enlarging breast mass with ultrasound-guided biopsy results consistent with atypical fibroepithelial proliferation that was highly concerning for a borderline phyllodes tumor. In this large, rare breast tumor that required en bloc pectoralis major resection, we describe the novel use of an immediate single pedicled DIEP flap for the resulting chest wall defect. The patient's postoperative course was uncomplicated, and she reported satisfactory cosmetic and functional outcomes at her initial postoperative follow-up visits. Our findings support the use of simple mastectomy with en bloc resection and immediate single-pedicled DIEP flap for the definitive treatment of giant phyllodes tumors. Our experience shows this is a safe and effective technique for achieving adequate oncologic resection while maintaining postoperative function and cosmesis, which are essential for patient quality of life.

A Case of Adult Multisystem Inflammatory Syndrome Following COVID-19 Vaccine.

Multisystem inflammatory syndrome is a life-threatening condition associated with elevated inflammatory markers and multiple organ injury. A diagnosis of exclusion, it has been reported after severe acute respiratory syndrome coronavirus 2 infection (SARS-CoV-2) in children and adults; recently it has been described in some post-COVID-19 vaccinated individuals. The prognosis with supportive care and immunomodulatory therapy is good, although some individuals may require treatment in the intensive care unit (ICU). Here we report a case of a 58-year-old man who developed multi-organ failure after receiving the second dose of the Moderna mRNA-1273 COVID-19 vaccine. He required critical organ support in the ICU. An extensive workup was done to rule out alternative infectious and inflammatory processes. Following a period of gradual in-hospital convalescence, our patient made a full recovery. To our knowledge, this is the first comprehensively described case of multisystem inflammatory syndrome associated with Moderna mRNA-1273 COVID-19 vaccine in an adult over 50 years of age.

Towards a Low-Cost Solution for Gait Analysis Using Millimeter Wave Sensor and Machine Learning.

Human Activity Recognition (HAR) that includes gait analysis may be useful for various rehabilitation and telemonitoring applications. Current gait analysis methods, such as wearables or cameras, have privacy and operational constraints, especially when used with older adults. Millimeter-Wave (MMW) radar is a promising solution for gait applications because of its low-cost, better privacy, and resilience to ambient light and climate conditions. This paper presents a novel human gait analysis method that combines the micro-Doppler spectrogram and skeletal pose estimation using MMW radar for HAR. In our approach, we used the Texas Instruments IWR6843ISK-ODS MMW radar to obtain the micro-Doppler spectrogram and point clouds for 19 human joints. We developed a multilayer Convolutional Neural Network (CNN) to recognize and classify five different gait patterns with an accuracy of 95.7 to 98.8% using MMW radar data. During training of the CNN algorithm, we used the extracted 3D coordinates of 25 joints using the Kinect V2 sensor and compared them with the point clouds data to improve the estimation. Finally, we performed a real-time simulation to observe the point cloud behavior for different activities and validated our system against the ground truth values. The proposed method demonstrates the ability to distinguish between different human activities to obtain clinically relevant gait information.

Prepectoral Conversion of Subpectoral Implants for Animation Deformity after Breast Reconstruction: Technique and Experience.

Implant-based breast reconstruction in postmastectomy patients is commonly performed in a submuscular plane. Following reconstruction, animation deformity can be a displeasing aesthetic result for patients. In addition, patients may experience more postoperative pain with a submuscular reconstruction. Prepectoral conversion of submuscular implant position is an option for addressing these concerns. We describe a detailed technique and review our results. METHODS: A retrospective review was conducted of all prepectoral conversions performed by the senior author (DSW) from 2017 to 2019 after IRB approval. All patients presented with animation deformity and another symptom such as asymmetry, pain, and/or capsular contracture. Patients underwent prepectoral conversion with smooth silicone gel implants. Demographic data, outcomes, and patient satisfaction were reviewed. RESULTS: Prepectoral conversion was performed in 33 consecutive patients (57 breasts) with animation deformity. Twelve patients had capsular contracture, seven complained of pain, and five had ruptured implants. Postoperative complications included three infections requiring implant removal in two breasts, one implant exposure and one hematoma requiring implant replacement, five seromas requiring aspiration, and one capsular contracture. Seven patients had contour abnormalities addressed with secondary autologous fat grafting. Ultimately, all patients had elimination of animation deformity and were satisfied with the results of the conversion. CONCLUSIONS: Unsatisfactory results of subpectoral implant reconstruction such as animation deformity and chronic pain have led the reconstructive surgeon to consider various techniques to address these issues. The conversion to a prepectoral plane will effectively eliminate animation deformity, resolve pain, and yield satisfactory results in these patients.

Leg Fidgeting Improves Executive Function following Prolonged Sitting with a Typical Western Meal: A Randomized, Controlled Cross-Over Trial.

Prolonged uninterrupted sitting and a typical Western meal, high in fat and refined sugar, can additively impair cognitive and cerebrovascular functions. However, it is unknown whether interrupting these behaviours, with a simple desk-based activity, can attenuate the impairment. The aim of this study was to determine whether regular leg fidgeting can off-set the detrimental effects of prolonged sitting following the consumption of a typical Western meal, on executive and cerebrovascular function. Using a randomized cross-over design, 13 healthy males consumed a Western meal and completed 180-min of prolonged sitting with leg fidgeting of 1 min on/4 min off (intervention [INT]) and without (control [CON]). Cognitive function was assessed pre and post sitting using the Trail Maker Test (TMT) parts A and B. Common carotid artery (CCA) blood flow, as an index of brain flow, was measured pre and post, and cerebral (FP1) perfusion was measured continuously. For TMT B the CON trial significantly increased (worsened) completion time (mean difference [MD] = 5.2 s, d = 0.38), the number of errors (MD = 3.33, d = 0.68) and cognitive fatigue (MD = 0.73, d = 0.92). Compared to CON, the INT trial significantly improved completion time (MD = 2.3 s, d = 0.97), and prevented declines in cognitive fatigue and a reduction in the number of errors. No significant changes in cerebral perfusion or CCA blood flow were found. Leg fidgeting for 1-min on/4-min off following a meal high in fats and refined sugars attenuated the impairment in executive function. This attenuation in executive function may not be caused by alterations in CCA blood flow or cerebral perfusion.

Central and peripheral arterial stiffness responses to uninterrupted prolonged sitting combined with a high-fat meal: a randomized controlled crossover trial.

Independently, prolonged uninterrupted sitting and the consumption of a meal high in saturated fats acutely disrupt normal cardiovascular function. Currently, the acute effects of these behaviors performed in combination on arterial stiffness, a marker of cardiovascular health, are unknown. This study sought to determine the effect of consuming a high-fat meal (Δ = 51 g fat) in conjunction with prolonged uninterrupted sitting (180 min) on measures of central and peripheral arterial stiffness. Using a randomized crossover design, 13 young healthy males consumed a high-fat (61 g) or low-fat (10 g) meal before 180 min of uninterrupted sitting. Carotid-femoral (cf) and femoral-ankle (fa) pulse wave velocity (PWV), aortic-femoral stiffness gradient (af-SG), superficial femoral PWV beta (ß), and oscillometric pulse wave analysis outcomes were assessed pre and post sitting. cfPWV increased significantly more following the high-fat (mean difference [MD] = 0.59 m·s-1) meal than following the low-fat (MD = 0.2 m·s-1) meal, with no change in faPWV in either condition. The af-SG significantly decreased (worsened) (ηp2 = 0.569) over time in the high- and low-fat conditions (ratio = 0.1 and 0.1, respectively). Superficial femoral PWVß significantly increased over time in the high- and low-fat conditions (ηp2 = 0.321; 0.8 and 0.4 m·s-1, respectively). Triglycerides increased over time in the high-fat trial only (ηp2 = 0.761). There were no significant changes in blood pressure. Consuming a high-fat meal prior to 180 min of uninterrupted sitting augments markers of cardiovascular disease risk more than consuming a low-fat meal prior to sitting.

Interest in Telehealth Among Patients With Chronic Retinal Conditions.

Purpose: This work investigated interest in telehealth services for patients with chronic retinal conditions. Methods: A single-center, multi-office study was conducted of patients with chronic retinal conditions who were seen by 1 of 4 physicians during June 2020. Patients whose next appointment was 6 months or later were telephoned. Patients completed a phone interest survey about their interest in a hybrid telehealth evaluation instead of a complete office evaluation with their provider. Results: Of 2136 patients reviewed, 453 met eligibility to participate in the survey. A total of 159 patients (35.1%) participated, of whom 91 (57.2%) indicated an interest in telehealth at their next follow-up visit. Of the 68 (42.8%) patients without a current interest in telehealth, 13 (19.1%) expressed interest in pursuing telehealth in the future. Age (P = .19), sex (P = .22), race (P = .79), office location (P = .19), number of prior visits (P = .58), and median household income by patient's zip code (P = .14) were not predictors of telehealth interest. Among diagnoses, dry age-related macular degeneration was associated (P = .04) with increased interest in telehealth. An increased number of ocular diagnoses were also found to predict a decreased (P = .04) interest in telehealth. multivariable analysis revealed healthcare provider as the only significant predictor for interest in telehealth (P = .03). Conclusions: Most patients with chronic retinal conditions may be interested in incorporating telehealth into routine care. Considerations should be made to evaluate interest in telehealth to guide patients to clinical experiences that best suit their needs.

Leucine Supplementation Increases Muscle Strength and Volume, Reduces Inflammation, and Affects Wellbeing in Adults and Adolescents with Cerebral Palsy.

BACKGROUND: Spastic cerebral palsy (CP) is characterized by muscle weakness owing, in part, to a blunted muscle protein synthetic response. This might be normalized by long-term leucine supplementation. OBJECTIVES: The study assessed the effects of 10 wk leucine supplementation in adolescents and adults with CP. METHODS: The study was a single-center randomized controlled trial. Twenty-four participants were randomly assigned to a control group (n = 12) or a leucine group (n = 12). l-Leucine (192 mg/kg body mass) was dissolved in water and administered daily for 10 wk. The primary outcome measures of elbow flexor muscle strength and muscle volume (measured by 3D ultrasound technique) and inflammation [C-reactive protein (CRP) concentration] were assessed before and after the 10 wk, alongside the secondary outcomes of body composition (measured by CP-specific skinfold assessment), metabolic rate (measured by indirect calorimetry), and wellbeing (measured by a self-reported daily questionnaire). Data were compared via a series of 2-factor mixed ANOVAs. RESULTS: Twenty-one participants completed the intervention (control group: n = 11, mean ± SD age: 18.3 ± 2.8 y, body mass: 48.8 ± 11.9 kg, 45% male; leucine group: n = 10, age: 18.6 ± 1.7 y, body mass: 58.3 ± 20.2 kg, 70% male). After 10 wk, there was a 25.4% increase in strength (P = 0.019) and a 3.6% increase in muscle volume (P = 0.001) in the leucine group, with no changes in the control group. This was accompanied by a 59.1% reduction in CRP (P = 0.045) and improved perceptions of wellbeing (P = 0.006) in the leucine group. No changes in metabolism or body composition were observed in either group (P > 0.05). CONCLUSIONS: Improvements in muscle strength and volume with leucine supplementation might provide important functional changes for adults and adolescents with CP and could be partly explained by reduced inflammation. The improved wellbeing highlights its capacity to improve the quality of daily living. This trial was registered at clinicaltrials.gov as NCT03668548.
