ABSTRACT
The National Football League (NFL) is a highly popular sport in the United States, attracting numerous aspiring athletes due to its lucrative pay and fame. However, the pursuit of a career in the NFL comes with significant health risks, particularly concussions and their long-term effects. Repeated head traumas in the NFL can lead to chronic traumatic encephalopathy (CTE), a neurodegenerative disease that is characterized by a spectrum ranging from cognitive and behavioral aberrations and has been linked to conditions such as Parkinson's and Alzheimer's diseases. Despite growing evidence, NFL officials have historically downplayed the connection between concussions and CTE, attributing symptoms to other factors such as performance-enhancing drugs. To address the concussion crisis, the NFL has implemented rule changes and partnered with engineers to develop safer helmets. However, the most effective approach to combating CTE involves early detection through MRI brain scans, which are a potential method for identifying the disease in living patients and subsequently facilitating early intervention. While other contact sports such as boxing have been shown to increase the risk of traumatic brain injury as well as CTE, the impact the NFL has on CTE is the most prominent in today's society. This editorial emphasizes the need for the NFL to acknowledge the clear link between concussions and CTE and to invest in comprehensive diagnostic and therapeutic strategies such as new monoclonal antibody therapies. Despite ethical and technical challenges, such as the use of embryonic stem cells and the risks associated with radioactive scans, advancing these methods could save lives and improve the long-term health outcomes of current and former NFL players. Enhanced understanding and proactive management of CTE are crucial for mitigating the severe impact of concussions in professional football.
ABSTRACT
Longitudinal bone growth is mediated through several mechanisms including macro- and micronutrients, and endocrine and paracrine hormones. These mechanisms can be affected by childhood obesity as excess adiposity may affect signaling pathways, place undue stress on the body, and affect normal physiology. This review describes the physiology of the epiphyseal growth plate, its regulation under healthy weight and obesity parameters, and bone pathology following obesity. A literature review was performed utilizing PubMed, PMC, NIH, and the Cochrane Database of Systematic Reviews pertinent to hormonal and nutritional effects on bone development, child obesity, and pathologic bone development related to weight. The review indicates a complex network of nutrients, hormones, and multi-system interactions mediates long bone growth. As growth of long bones occurs during childhood and the pubertal growth spurt, pediatric bones require adequate levels of minerals, vitamins, amino acids, and a base caloric supply for energy. Recommendations should focus on a nutrient-dense dietary approach rather than restrictive caloric diets to maintain optimal health. In conclusion, childhood obesity has profound multifaceted effects on the developing musculoskeletal system, ultimately causing poor nutritional status during development. Weight loss, under medical supervision, with proper nutritional guidelines, can help counteract the ill effects of childhood obesity.
ABSTRACT
INTRODUCTION: Low back pain has become a substantial health problem in all developed countries. Many healthcare professionals and content creators have begun sharing their treatment methods and opinions through social media, especially the video-based platform TikTok. TikTok has been downloaded more than 2.6 billion times with over a billion daily users. Its influence on public health makes it imperative that information be accurate and safe. This study aims to analyze TikTok's most popular content on lower back pain and how orthopaedic surgeons contribute on this growing platform. OBJECTIVES: To analyze TikTok's most popular content on lower back pain and how orthopaedic surgeons are and can contribute on this growing platform. METHODS: A TikTok search conducted on April 22, 2023, using the terms '#lowerbackpain'and '#lowbackpainrelief,' resulted in numerous videos, 100 of which met inclusion criteria. Videos were included if they were related to the content, had more than 1000 views, were in English, and were not duplicates. Video characteristics were recorded and evaluated for quality by two reviewers using DISCERN. A two-sample t-test was used to assess differences. RESULTS: Overall, the top videos on lower back pain had an average of 2,061,396 views, with a mean DISCERN score of 34. The mean total DISCERN score was 36 and 34 for physicians and nonphysicians, respectively, while the video by the orthopaedic surgeon (n = 1) scored 31. The most recommended treatments included at-home exercises (n = 75) and visiting a chiropractor (n = 4). CONCLUSION: We find that the information presented by nonphysicians offered quick, at-home fixes to medical problems without offering any research or proven data to support their claims. We cannot overlook Tiktok's immense influence in the realm of orthopaedic health as it has become a sphere of information dissemination and education. Thus, we suggest that there is not necessarily a need for a greater number of surgeons and/or resident physicians to involve themselves on the platform, but rather the involvement of governing bodies and spine societies to put out position statements for our patients.

STUDY DESIGN: Retrospective Cohort. OBJECTIVE: We investigate whether duration of symptoms a patient experiences prior to lumbar microdiscectomy affects pain, lifestyle, and return to work metrics after surgery. METHODS: A retrospective review of patients with a diagnosis of lumbar radiculopathy undergoing microdiscectomy was conducted using a statewide registry. Patients were grouped based on self-reported duration of symptoms prior to surgical intervention (Group 1: symptoms less than 3 months; Group 2: symptoms between 3 months and 1 year; and Group 3: symptoms greater than 1 year). Radicular pain scores, PROMIS PF Physical Function measure (PROMIS PF), EQ-5D scores, and return to work rates at 90 days, 1 year, and 2 years after surgery were compared using univariate and multivariate analysis. RESULTS: There were 2408 patients who underwent microdiscectomy for lumbar disc herniation for radiculopathy with 532, 910, and 955 in Groups 1, 2, and 3, respectively. Postoperative leg pain was lower for Group 1 at 90 days, 1 year, and 2 years compared to Groups 2 and 3 (P < .05). Postoperative PROMIS PF and EQ-5D scores were higher for Group 1 at 90 days, 1 year, and 2 years compared to Groups 2 and 3 (P < .05). CONCLUSION: Patients with prolonged symptoms prior to surgical intervention experience smaller improvements in postoperative leg pain, PROMIS PF, and EQ-5D than those who undergo surgery earlier. Patients undergoing surgery within 3 months of symptom onset have the highest rates of return to work at 1 year after surgery.
ABSTRACT
STUDY DESIGN: Systematic Review. OBJECTIVES: To determine the efficacy and overall outcomes of iFactor/ABM/P-15 following lumbar spine surgery. METHODS: We performed a search of the Cochrane Library, Medline Ovid, PubMed, and SCOPUS databases from inception until August 2023. Eligible studies included outcomes of patients receiving iFactor following lumbar spine surgery. The primary outcomes of interest were fusion rates and iFactor efficacy after lumbar surgery in patients who received iFactor. Secondary outcomes included patient-reported outcomes and complication rates. RESULTS: A total of 766 titles were initially screened. After inclusion criteria were applied, 5 studies (388 patients) were included, which measured overall outcomes of iFactor/ABM/P-15 following lumbar spine surgery. These studies showed acceptable reliability for inclusion based on the Methodical Index for Non-Randomized studies and Critical Appraisal Skills Programme assessment tools. iFactor/ABM/P-15 facilitated significantly faster bone development in various procedures while maintaining favorable clinical outcomes compared to traditional grafts. CONCLUSIONS: This systematic review found that iFactor/ABM/P-15 use for lumbar spine surgery maintains similar managing patient-reported outcomes relative to other grafting methods. In regard to rates of fusion, iFactor/ABM/P-15 showed a significantly faster rate of fusion when compared to traditional grafts including allograft, autograft, demineralized bone matrix (DBM), and recombinant human bone morphogenetic protein-2 (rhBMP-2). Future multicenter randomized control trials with larger sample sizes are recommended to further assess iFactor/ABM/P-15 efficacy in lumbar spine surgery.
ABSTRACT
Stroke is one of the leading causes of death and disability. To address this challenge, microwave imaging has been proposed as a portable medical imaging modality. However, accurate stroke classification using microwave signals is still an open challenge. In addition, identified features of microwave signals used for stroke classification need to be linked back to the original data. This work attempts to address these issues by proposing a wavelet convolutional neural network (CNN), which combines multiresolution analysis and CNN to learn distinctive patterns in the scalogram for accurate classification. A game theoretic approach is used to explain the model and indicate distinctive features for discriminating stroke types. The proposed algorithm is tested in simulation and experiments. Different types of noise and manufacturing tolerances are modeled using data collected from healthy human trials and added to the simulation data to bridge the gap between the simulation and real-life data. The achieved classification accuracy using the proposed method ranges from 81.7% for 3D simulations to 95.7% for lab experiments using simple head phantoms. Obtained explanations using the method indicate the relevance of wavelet coefficients on frequencies 0.95-1.45 GHz and the time slot of 1.3 to 1.7 ns for distinguishing ischemic from hemorrhagic strokes.
ABSTRACT
The landscape of orthopedic joint surgeries, specifically total hip arthroplasty (THA) and total knee arthroplasty (TKA), is rapidly changing, and artificial intelligence (AI) along with robotics is at the helm of this transformation. These technologies, working synergistically, have introduced unprecedented levels of precision and personalization to surgical procedures, thereby significantly enhancing patient outcomes. In this editorial, we explore the changing perspectives of orthopedic surgeons toward AI and robotics and dissect the incorporation of these technologies in surgeries, their associated advantages, their inherent limitations, and potential future prospects. We draw from a host of recent studies to provide a comprehensive understanding of how these transformative technologies can augment surgical performance and patient care.
ABSTRACT
In the dynamic realm of spinal surgery, the integration of virtual reality (VR) and augmented reality (AR) technologies is heralding a transformative era. These cutting-edge tools are not only reshaping the training landscape for surgical trainees, offering immersive and interactive experiences but are also enhancing the surgical precision of seasoned professionals in the operating room. While the potential of VR and AR is vast, their adoption is tempered by significant costs and challenges in seamless integration. As the spinal surgery community looks ahead, it becomes imperative to emphasize the validation, reliability, and thorough cost-benefit analysis of these technologies. This article delves into the current applications, benefits, challenges, and future trajectories of VR and AR in spinal surgery, underscoring their pivotal role in the evolution of immersive healthcare.
ABSTRACT
INTRODUCTION: Unicompartmental designs and techniques have been developed to preserve bone stock and minimize soft tissue trauma. Early modern designs and techniques have been introduced with little support in the peer-reviewed literature. MATERIAL AND METHODS: From October 2002 to May 2004, 64 consecutive DePuy Preservation unicondylar knee arthroplasties (UKAs) were performed in 56 patients. Two patients died of unrelated consequences, leaving 62 UKAs for review (55 medial, 7 lateral). All procedures were performed through a quadriceps-sparing approach. All components were cemented, including an all polyethylene tibial component. Clinical and radiographic follow-up data were reviewed and analyzed. RESULTS: At an average follow-up of 2.5 years, six (11%) of the medial tibial components have subsided. Of these, four had moderate-to-severe pain, one did require a revision to a total knee arthroplasty (TKA), and another did stabilize. An additional two patients continued to have knee pain (one requiring conversion to TKA), leaving a total of 55 UKAs (89%) functioning well at early follow-up. Additional complications have included four deep vein thromboses, three cardiac issues following the index procedure, one surgical site infection, one intraoperative medial femoral condyle fracture, and one reoperation for loose cement fragments. CONCLUSION: This study demonstrates a high rate of subsidence for all-polyethylene tibial components used in UKA, resulting in pain and failure of the arthroplasty. Despite the less invasive approach, we found complications that are usually associated with TKA surgery as well as those unique to UKA.
ABSTRACT
Motivational deficits in schizophrenia may interact with foundational cognitive processes including learning and memory to induce impaired cognitive proficiency. If such a loss of synergy exists, it is likely to be underpinned by a loss of synchrony between the brains learning and reward sub-networks. Moreover, this loss should be observed even during tasks devoid of explicit reward contingencies given that such tasks are better models of real world performance than those with artificial contingencies. Here we applied undirected functional connectivity (uFC) analyses to fMRI data acquired while participants engaged in an associative learning task without contingencies or feedback. uFC was estimated and inter-group differences (between schizophrenia patients and controls, n = 54 total, n = 28 patients) were assessed within and between reward (VTA and NAcc) and learning/memory (Basal Ganglia, DPFC, Hippocampus, Parahippocampus, Occipital Lobe) sub-networks. The task paradigm itself alternated between Encoding, Consolidation, and Retrieval conditions, and uFC differences were quantified for each of the conditions. Significantly reduced uFC dominated the connectivity profiles of patients across all conditions. More pertinent to our motivations, these reductions were observed within and across classes of sub-networks (reward-related and learning/memory related). We suggest that disrupted functional connectivity between reward and learning sub-networks may drive many of the performance deficits that characterize schizophrenia. Thus, cognitive deficits in schizophrenia may in fact be underpinned by a loss of synergy between reward-sensitivity and cognitive processes.

INTRODUCTION: Hand masses are fairly common. While most of these masses are either ganglion cysts or benign tumors, masses in the first web space are not rare, and they may in fact represent a variety of lesions. These include both benign and malignant tumors, metastases, or congenital and anomalous structures, and may involve nerves, vascular structures, connective tissue, and joints. METHODS: In this retrospective case series, data on 12 cases of first dorsal web space hand mass treated at our center over a period of five years were collected and analyzed. RESULTS: Twelve consecutive patients presenting with a first dorsal web space hand mass over a period of five years were reviewed. This represented a group of nine females and three males, with a mean age of 53 years (range = 16-70 years). Seven patients had a mass on the right side and five on the left side. The surgical approach to resect the mass in all 12 patients was dorsal. The most common diagnosis was ganglion cyst (50%), followed by lipoma (25%) and aneurysm (16.6%). There was one case of eccrine spiradenoma. CONCLUSION: First dorsal web space hand masses can encompass multiple different pathologies, and the first web space has an intricate anatomy. Both of these factors mandate a careful approach that includes meticulous preoperative planning with appropriate advanced imaging studies, which helps to make the surgical procedure more efficient and accurate.
ABSTRACT
STUDY DESIGN: Systematic Review. OBJECTIVES: To determine the radiographic and clinical utility of postoperative orthoses following cervical spine surgery. METHODS: We performed a search of the PubMed, Cochrane Library, Medline Ovid, and SCOPUS databases from inception until November 2021. Eligible studies included outcomes of postoperative bracing vs no bracing following cervical spine surgery. The primary outcome of interest was fusion rates after cervical surgery in braced vs unbraced patients. Secondary outcomes included patient reported outcomes and complication rates. RESULTS: A total of 3232 titles were initially screened. After inclusion criteria were applied, 7 studies (550 patients) were included, which compared results of braced vs unbraced patients after cervical spine surgery. These studies showed acceptable reliability for inclusion based on the Methodical Index for Non-Randomized studies and Critical Appraisal Skills Programme assessment tools. There were no significant differences in fusion rates or complications between braced vs unbraced patients identified in any study. Patient reported pain and quality of life measures between braced and unbraced groups varied amongst studies, without any clear overall advantages favoring either method. CONCLUSIONS: This systematic review found that external bracing, though widely used following cervical spine surgery, may not offer any advantages in patient-reported outcomes, as compared to not bracing. In regard to the effect of bracing on fusion rates, no strong consensus can be made as the methods of fusion assessment in the included studies were heterogenous and suboptimal. Future high-quality studies using recommended methods of fusion assessment are needed to adequately address this important question.
ABSTRACT
Introduction Dry eye disease (DED) is a common ocular pathology with significant impacts on both quality of life and visual function. One platform where individuals are receiving healthcare information is TikTok, the world's fastest-growing social media platform. Though used by more than one billion users, current literature is not established to assess the quality of information on TikTok. The purpose of this study was to assess the quality of DED-related medical information present on TikTok. Methods We conducted a cross-sectional analysis of DED content on TikTok, utilizing the search term #DryEye to assess the top 150 videos appearing on December 20, 2021. Included videos were analyzed for descriptive statistics, including views, likes, uploader profession, and the number of uploader followers. Videos were assessed utilizing DISCERN, a tool used to appraise consumer health information. The one-way analysis of variance (ANOVA) was used to determine statistical significance groups. Results A total of 101 videos were included in the final analysis. When comparing content creators, physicians received a significantly greater number of views and higher DISCERN scores (p<0.05) than non-physician medical providers and non-medical individuals. The content of the videos were educational content (n=39, 38.6%) or treatment information (n=37, 36.6%), followed by home remedies (n=10, 9.9%) and personal anecdotes (n=8, 7.9%). Videos with rich supplementary visuals (multiple images/moving images) had higher DISCERN scores compared to videos with no supplementary visuals or one supplementary visual (p<0.01). Conclusion With the growing popularity of TikTok, it is important to provide high-quality information to ensure the dissemination of medically accurate information and reduce the prevalence of disinformation. Our results demonstrate that while TikTok is a powerful platform, the quality of videos can still be vastly improved. Content creators, regardless of profession, can improve their DISCERN through listing sources, comparing treatments, and discussing risks/outcomes of various treatment modalities.
ABSTRACT
Background Traumatic upper cervical spine injuries (tUCSI) are generally caused by high-impact injuries to the C1-C2 vertebral level. The current literature is limited with regards to comparing epidemiological trends, treatment options, and overall outcomes for tUCSI within the pediatric cohort. The purpose of this study was to analyze pediatric tUCSI epidemiological data, potential variations in treatment and patient outcomes, and to evaluate any specific trends that may be clinically relevant. Methodology We conducted a retrospective cohort study on pediatric patients ages 1 day to 16 years old, admitted for tUCSI over the past 10 years (1/2011 to 1/2021) at a Midwest level 1 trauma center. Retrospective data was queried using ICD-9 and ICD-10 diagnosis codes for tUCSI. Children were stratified into three age groups: Group 1 - Infants and Toddlers (children under three years of age); Group 2 - Young Children (children between three and seven years of age); Group 3 - Juveniles and Adolescents (children between the ages of seven and 16). Numerical data and categorical variables were summarized and the normality of the distribution of data was evaluated using the Anderson-Darling normality test. Differences between the age groups were examined using either an unpaired, independent Two-Sample t-test or Unpaired Mann-Whitney U test. Pearson's chi-squared or Fisher's exact tests were used to compare categorical data between groups. Results Forty total patients were included in the final analysis, 23 female (57.5%) and 17 male (42.5%). The mean age was 11 ± 4 (range 2-16). Overall, the most common mechanism of injury was a motor vehicle collision (n=16, 40%), followed by sports injury (n=13, 32.5%), falls (n=6, 15%), and unknown mechanism (n=5, 12.5%). The most common mechanism of injury in young children was a fall (n=4, 57.5%, p<0.001). Adolescents and Juveniles significantly suffer from sports injuries compared to young children (n=13, 39.4%, p=0.043). Mechanisms of injuries presented with unique associated concomitant injuries. The most common associated sites of injuries were lower cervical spine (n=31, 77.5%), and skull injury (n=4, 10%). The vast majority of these cases were managed nonoperatively (pain medication and non-operative cervical orthosis) (n=36, 90%). Mortality and morbidity rates from tUCSI were rare in our cohort (n=1, 2.5%). Conclusion This study found that the majority of pediatric tUCSI patients can be managed nonoperatively, with dislocations and spinal instability being the most common indications for operative management. Commonly used non-operative external fixation methods include cervical collars and Minerva jackets. Our cohort showed very low mortality and morbidity rates, however, these preliminary results will require validation by future prospective multicenter studies.
ABSTRACT
Cervical spine pathology is becoming increasingly prevalent with an aging world population and is associated with significant morbidity, affecting all areas of the world. This review was undertaken to provide a global perspective on cervical spine pathology, including epidemiology, burden of disease, access to care, and plan of care in both developed and developing low- and middle-income countries (LMICs). We found that epidemiology, access to care, plan of care, and health outcomes were relatively similar between nations with similar economies. However, these aspects change dramatically when comparing developing nations to LMICs, with LMICs displaying substantial barriers to care and subsequently higher rates of morbidity and mortality. There is currently a need for large-scale, global, prospective multicenter studies that analyze not only the epidemiology and treatment of cervical spine pathology, but also consider patient outcomes.
ABSTRACT
BACKGROUND: Prior to 2003 in Bangladesh, ~ 80% of kidney-failure patients could not afford treatment. The Kidney Foundation Bangladesh (KFB) was formed in 2003 with an aim to create awareness, to promote prevention of kidney disease to families and population, at risk as well as offer treatment to those afflicted with kidney failure. METHODS: KFB runs a 150-bed hospital for treatment of kidney disease, dialysis, and transplantation at an affordable price. New patients visiting the OPD pay only US$ 5.00 to consult a specialist, and dialysis and transplant patients pay US$1 for each consultation. All laboratory tests are discounted by 30% for all patients except patients with dialysis and transplantation who enjoy a 50% discount. Patients on HD pay only US$ 20.00 per session, and a renal transplant surgery costs US$ 3,000.00. RESULTS: From October 2004 to December 2014, there were 102,578 patients who received treatment in OPD in KFB at an affordable price. Similarly, more than 40,000 people per year benefited from various laboratory tests. A total of 11,099 patients were admitted in KFB hospital from January 2010 to December 2014. Of them, 2,409 (22%) were diagnosed as ESRD, and all of them were initially managed with dialysis either through a noncuffed catheter (82%) or by an AV fistula (8%); of the 388 continued on HD, 300 underwent transplantation, 289 agreed to shift to CAPD treatment, and rest of the patients were shifted to other HD centers. Simultaneously, a total of 3,600 patients were screened in rural, urban, and disadvantaged populations from 2004 to 2007 for detection of CKD. CONCLUSION: KFB is offering treatment for patients with kidney disease and kidney failure, not only at an affordable price, but also without compromising quality.
