RESUMO
OBJECTIVES: To determine the incidence rate of suicide from 2002 to 2022 among athletes from the National Collegiate Athletic Association (NCAA) and assess for potential differences by, sex, race, division and sport. METHODS: NCAA athlete deaths over a 20-year period from 2002 to 2022 were identified. Poisson regression models were built to assess changes in incidence rates over time. Linear and quadratic fits between year and suicide incidence for males and females were evaluated. RESULTS: Of 1102 total deaths, 128 (11.6%) deaths by suicide were reported (male n=98, female n=30). The overall incidence was 1:71 145 athlete-years (AYs). Over the last decade, suicide was the second most common cause of death after accidents. The proportion of deaths by suicide doubled from the first 10 years (7.6%) to the second 10 years (15.3%). The suicide incidence rate for males increased linearly (5-year incidence rate ratio 1.32 (95% CI 1.14 to 1.53)), whereas a quadratic association was identified among female athletes (p=0.002), with the incidence rate reaching its lowest point in females in 2010-2011 and increasing thereafter. Male cross-country athletes had the highest suicide incidence rate (1:29 815 AYs) and Division I and II athletes had a higher suicide incidence rate than Division III athletes. No significant differences in suicide incidence rates by sex, race or sport were identified. CONCLUSION: Deaths by suicide among NCAA athletes increased in both males and females throughout the 20-year study period, and suicide is now the second most common cause of death in this population. Greater suicide prevention efforts geared towards NCAA athletes are warranted.

OBJECTIVE: Health disparities are widely prevalent; however, little has been done to examine and address their causes and effects in sports and exercise medicine (SEM). We aimed to summarise the focus areas and methodology used for existing North American health disparity research in SEM and to identify gaps in the evidence base. DESIGN: Scoping review. DATA SOURCES: Systematic literature search of PubMed, Scopus, SPORTDiscus, CINAHL Plus with Full Text, Web of Science Core Collection and Cochrane Central Register of Controlled Trials. ELIGIBILITY CRITERIA: Full-text, peer-reviewed manuscripts of primary research, conducted in North America; published in the year 2000 or after, in English; and focusing on organised sports were included. RESULTS: 103 articles met inclusion criteria. Articles were classified into five focus areas: access to and participation in sports (n=45), access to SEM care (n=28), health-related outcomes in SEM (n=24), provider representation in SEM (n=5) and methodology (n=1). Race/ethnicity (n=39), socioeconomic status (n=28) and sex (n=27) were the most studied potential causes of health disparities, whereas sexual orientation (n=5), location (rural/urban/suburban, n=5), education level (n=5), body composition (n=5), gender identity (n=4) and language (n=2) were the least studied. Most articles (n=74) were cross-sectional, conducted on youth (n=55) and originated in the USA (n=90). CONCLUSION: Health disparity research relevant to SEM in North America is limited. The overall volume and breadth of research required to identify patterns in a heterogeneous sports landscape, which can then be used to inform positive change, need expansion. Intentional research focused on assessing the intersectionality, causes and consequences of health disparities in SEM is necessary.

BACKGROUND: While hepatitis A and B are well-known causes of acute liver failure (ALF), few well-documented cases of hepatitis C virus (HCV) infection (absent preexisting liver disease or other liver insults) have been described that result in ALF. We reviewed the Acute Liver Failure Study Group registry for evidence of HCV as a primary or contributing cause to ALF. METHODS: From January 1998 to January 2017, 2,332 patients with ALF (INR ≥ 1.5, any degree of hepatic encephalopathy) and 667 with acute liver injury (ALI; INR ≥ 2.0, no hepatic encephalopathy) were enrolled. Anti-HCV testing was done routinely, with confirmatory RT-PCR testing for HCV RNA where necessary. RESULTS: A total of 136 patients were anti-HCV-antibody positive, as follows: 56 HCV RNA negative, 65 HCV RNA positive, and 8 with no result nor sera available for testing. Only three subjects with ALI/ALF were determined to represent acute HCV infection. Case 1: 47-year-old female with morbid obesity (BMI 52.4) developed ALF and recovered, experiencing anti-HCV seroconversion. Case 2: 37-year-old female using cocaine presented with ALI and fully recovered. Case 3: 54-year-old female developed ALF requiring transplantation and was anti-HCV negative but viremic prior to transplant experiencing anti-HCV seroconversion thereafter. Among 1636 APAP overdose patients, the 52 with concomitant chronic HCV had higher 3-week mortality than the 1584 without HCV (31% vs 17%, p = 0.01). CONCLUSIONS: ALI/ALF solely related to acute hepatitis C infection is very rare. Chronic HCV infection, found in at least 65 (2.2%) of ALI/ALF patients studied, contributed to more severe outcomes in APAP ALI/ALF; ClinicalTrials.gov number, NCT000518440. Trial Registration ClinicalTrials.gov number NCT000518440.

Analytical spectroscopy methods have shown many possible uses for nuclear material diagnostics and measurements in recent studies. In particular, the application potential for various atomic spectroscopy techniques is uniquely diverse and generates interest across a wide range of nuclear science areas. Over the last decade, techniques such as laser-induced breakdown spectroscopy, Raman spectroscopy, and x-ray fluorescence spectroscopy have yielded considerable improvements in the diagnostic analysis of nuclear materials, especially with machine learning implementations. These techniques have been applied for analytical solutions to problems concerning nuclear forensics, nuclear fuel manufacturing, nuclear fuel quality control, and general diagnostic analysis of nuclear materials. The data yielded from atomic spectroscopy methods provide innovative solutions to problems surrounding the characterization of nuclear materials, particularly for compounds with complex chemistry. Implementing these optical spectroscopy techniques can provide comprehensive new insights into the chemical analysis of nuclear materials. In particular, recent advances coupling machine learning methods to the processing of atomic emission spectra have yielded novel, robust solutions for nuclear material characterization. This review paper will provide a summation of several of these recent advances and will discuss key experimental studies that have advanced the use of analytical atomic spectroscopy techniques as active tools for nuclear diagnostic measurements.
RESUMO
ABSTRACT: The COVID-19 pandemic has created numerous challenges in all walks of life. One such challenge was the strain and subsequent effects on medical education, including the elimination of in-person learning opportunities. Consequently, in March of 2020, a nationwide Sports Medicine fellowship online education series was developed. Presentations were available for live and recorded viewing. Over the course of the 2020-2021 academic year, 38 presentations were offered, covering 45 topics. Live viewership totaled nearly 1600 through the year, while views of recorded lecture reached nearly 34,000. There was no statistical difference in the number of viewers for musculoskeletal versus nonmusculoskeletal topics in either the live (46.50 ± 35.37 vs. 43.38 ± 27.28 viewers, respectively; P = 0.77) or recorded formats (843.60 ± 337.66 vs 876.67 ± 624.70 viewers, respectively; P = 0.85). This article presents the novel approach to sports medicine education by the American Medical Society for Sports Medicine in the 2020-2021 academic year through the genesis the National Online Fellowship Education Program along with analyses of viewership data.

INTRODUCTION: Idiosyncratic drug-induced liver injury (DILI) is the second leading cause of acute liver failure (ALF) in the United States. Our study aims were to characterize secular trends in the implicated agents, clinical features, and outcomes of adults with DILI ALF over a 20-year period. METHODS: Among 2,332 patients with ALF enrolled in the ALF Study Group registry, 277 (11.9%) were adjudicated as idiosyncratic DILI ALF (INR ≥ 1.5 and hepatic encephalopathy) through expert opinion. The 155 cases in era 1 (January 20, 1998-January 20, 2008) were compared with the 122 cases in era 2 (January 21, 2008-January 20, 2018). RESULTS: Among 277 cases of DILI ALF, 97 different agents, alone or in combination, were implicated: antimicrobials, n = 118 (43%); herbal/dietary supplements (HDS), n = 42 (15%); central nervous system agents/illicit substances, n = 37 (13%); oncologic/biologic agents, n = 29 (10%); and other, n = 51 (18%). Significant trends over time included (i) an increase in HDS DILI ALF (9.7% vs 22%, P < 0.01) and decrease in antimicrobial-induced DILI ALF (45.8% vs. 38.5%, P = 0.03) and (ii) improved overall transplant-free survival (23.5%-38.7%, P < 0.01) while the number of patients transplanted declined (46.4% vs 33.6%, P < 0.03). DISCUSSION: DILI ALF in North America is evolving, with HDS cases rising and other categories of suspect drugs declining. The reasons for a significant increase in transplant-free survival and reduced need for liver transplantation over time remain unclear but may be due to improvements in critical care, increased NAC utilization, and improved patient prognostication.

This work investigates and applies machine learning paradigms seldom seen in analytical spectroscopy for quantification of gallium in cerium matrices via processing of laser-plasma spectra. Ensemble regressions, support vector machine regressions, Gaussian kernel regressions, and artificial neural network techniques are trained and tested on cerium-gallium pellet spectra. A thorough hyperparameter optimization experiment is conducted initially to determine the best design features for each model. The optimized models are evaluated for sensitivity and precision using the limit of detection (LoD) and root mean-squared error of prediction (RMSEP) metrics, respectively. Gaussian kernel regression yields the superlative predictive model with an RMSEP of 0.33% and an LoD of 0.015% for quantification of Ga in a Ce matrix. This study concludes that these machine learning methods could yield robust prediction models for rapid quality control analysis of plutonium alloys.

Sports ultrasound is commonly used by sports medicine physicians to enhance diagnostic and procedural accuracy. This expert consensus statement serves as an update to the 2015 American Medical Society for Sports Medicine recommended sports ultrasound curriculum for sports medicine fellowships. Although written in the context of the American sports medicine fellowship training model, we present a stepwise progression in both diagnostic and interventional sports ultrasound that may be applicable to the broader sports medicine community. The curriculum is divided into 12 units with each unit including didactic instructional sessions, practical hands-on instruction, independent scanning practice sessions and mentored clinical experience. To assist with prioritisation of learning, we have organised relevant pathology and procedures as essential, desirable and optional The expanded content can serve as an outline for continuing education postfellowship or for any physician to further advance their sports ultrasound knowledge and skill. We also provide updated scanning protocols, sample milestones and a sample objective structured clinical examination to aid fellowships with implementation of the curriculum and ongoing assessment of fellow progress.

OBJECTIVES: We assessed whether the presence and character of a cardiac murmur in adolescents were associated with structural heart disease that confers risk of sudden cardiac death (SCD). METHODS: We performed a retrospective analysis of 15 141 adolescents age 12-19 who underwent a heart screen with history, physical examination and ECG. Participants with any screening abnormality underwent an echocardiogram for the assessment of structural heart disease. Murmurs were classified as physiological or pathological according to standard clinical criteria, and participants with murmurs were compared with a comparison group without murmurs. The primary outcome was echocardiogram-detected structural heart disease associated with SCD. RESULTS: 905 participants with a cardiac murmur (mean age 15.8; 58% male) and 4333 participants without a murmur (comparison group; mean age 15.8; 55% male) had an echocardiogram to detect structural heart disease. 743 (82%) murmurs were described as physiological and 162 (18%) as pathological. Twenty-five (2.8%) participants with murmurs and 61 (1.4%) participants without murmurs had structural heart disease. Three (0.3%) participants in the murmur group were diagnosed with hypertrophic cardiomyopathy (HCM) which was the only identified condition associated with SCD. Two participants with HCM had physiological murmurs, one had a pathological murmur, and all three had an abnormal ECG. The most common minor structural heart disease was bicuspid aortic valve in both the murmur (7; 0.8%) and comparison (20; 0.5%) groups. The positive predictive value of physiological versus pathological murmurs for identifying any structural heart disease was 2.4% versus 4.3% (p=0.21), respectively. The positive predictive value of having any murmur versus no murmur for identifying structural heart disease was 2.8% versus 1.4% (p=0.003), respectively. CONCLUSIONS: In adolescents, the traditional classification of cardiac murmurs as 'physiologic' or 'pathologic' does not differentiate for structural heart disease that puts individuals at risk for SCD. We recommend ECG evaluation in all patients with a cardiac murmur found during preparticipation screening to increase detection of HCM.

ABSTRACT: Scholarly activity requirements for primary care sports medicine fellowship programs are increasing and the current Accreditation Council for Graduate Medicine Education (ACGME) expectations for fellows and core faculty are more demanding than those found in medicine residencies. A review of existing literature fails to identify any published guidelines on how to pursue scholarly activity within the sports medicine fellowship year. Such a deficiency may be critical for fellowship programs that are struggling to produce scholarship with a 1-year timeframe. This document intends to be a resource for all sports medicine fellowship programs by defining acceptable pieces of scholarly activity, delineating how a project may be completed during fellowship, and outlining avenues to educate others in the topic of choice. Adoption of this curriculum will guide fellows to meet ACGME-mandated scholarship requirements while assisting core faculty in meeting academic promotion criteria.

BACKGROUND: Delays in diagnosis and treatment have been reported for many cancers, with resultant stage migration and worse survival; however, few data exist in patients with hepatocellular carcinoma (HCC). These data are of particular importance in light of the COVID-19 pandemic, which has caused disruptions in healthcare processes and may continue to impact cancer care for the foreseeable future. The aim of our study was to characterize the prevalence and clinical significance of diagnostic and treatment delays in patients with HCC. METHODS: We performed a retrospective cohort study of consecutive patients diagnosed with HCC between January 2008 and July 2017 at 2 US health systems. Diagnostic and treatment delays were defined as >90 days between presentation and HCC diagnosis and between diagnosis and treatment, respectively. We used multivariable logistic regression to identify factors associated with diagnostic and treatment delays and Cox proportional hazard models to identify correlates of overall survival. RESULTS: Of 925 patients with HCC, 39.0% were diagnosed via screening, 33.1% incidentally, and 27.9% symptomatically. Median time from presentation to diagnosis was 37 days (interquartile range, 18-94 days), with 120 patients (13.0%) experiencing diagnostic delays. Median time from HCC diagnosis to treatment was 46 days (interquartile range, 29-74 days), with 17.2% of patients experiencing treatment delays. Most (72.5%) diagnostic delays were related to provider-level factors (eg, monitoring indeterminate nodules), whereas nearly half (46.2%) of treatment delays were related to patient-related factors (eg, missed appointments). In multivariable analyses, treatment delays were not associated with increased mortality (hazard ratio, 0.90; 95% CI, 0.60-1.35); these results were consistent across subgroup analyses by Barcelona Clinic Liver Cancer stage and treatment modality. CONCLUSIONS: Diagnostic and therapeutic delays exceeding 3 months are common in patients with HCC; however, observed treatment delays do not seem to significantly impact overall survival.

BACKGROUND: The novel coronavirus pandemic continues to ravage communities across the United States. Opinion surveys identified the importance of political ideology in shaping perceptions of the pandemic and compliance with preventive measures. OBJECTIVE: The aim of this study was to measure political partisanship and antiscience attitudes in the discussions about the pandemic on social media, as well as their geographic and temporal distributions. METHODS: We analyzed a large set of tweets from Twitter related to the pandemic, collected between January and May 2020, and developed methods to classify the ideological alignment of users along the moderacy (hardline vs moderate), political (liberal vs conservative), and science (antiscience vs proscience) dimensions. RESULTS: We found a significant correlation in polarized views along the science and political dimensions. Moreover, politically moderate users were more aligned with proscience views, while hardline users were more aligned with antiscience views. Contrary to expectations, we did not find that polarization grew over time; instead, we saw increasing activity by moderate proscience users. We also show that antiscience conservatives in the United States tended to tweet from the southern and northwestern states, while antiscience moderates tended to tweet from the western states. The proportion of antiscience conservatives was found to correlate with COVID-19 cases. CONCLUSIONS: Our findings shed light on the multidimensional nature of polarization and the feasibility of tracking polarized opinions about the pandemic across time and space through social media data.

This American Medical Society for Sports Medicine position statement update is directed towards healthcare providers of patients involved in sport and exercise. There have been significant advances in clinical and scientific research in the understanding of blood-borne pathogens (BBPs), and this update incorporates these advancements. This document is intended as a general guide to clinical practice based on the current state of the evidence, while acknowledging the need for modification as new knowledge becomes available. Confirmed transmission of BBPs during sport is exceedingly rare. There are no well-documented reports of HIV, HCV or HDV transmission during sport. There is also no evidence for universal testing for BBPs as a specific requirement for participation in sports. Competitive athletes and non-athletes should follow appropriate general public health agency recommendations for screening for BBPs, considering their individual risk factors and exposures. Standard (universal) precautions must be followed by those providing care to athletes. Exercise and athletic participation can help promote a healthy lifestyle for persons living with BBPs. Those with acute symptomatic BBP infection should limit exercise intensity based on their current health status. Education is the key tool for preventing BBP transmission. Research gaps include evaluation of the prevalence of BBP infections in competitive athletes, the effects of long-term, intense training on infected athletes and the effects of BBP treatment therapies on performance.

OBJECTIVE: To identify factors associated with entry into primary care sports medicine (PCSM) fellowship programs. DESIGN: Primary care sports medicine fellowship directors (FDs) and fellowship faculty were surveyed regarding preferences for accepting applicants into their programs. SETTING: Survey study. PARTICIPANTS: Primary care sports medicine FDs and fellowship faculty. ASSESSMENT OF RISK FACTORS: Questions were designed to delineate factors [clinical experience, letters of recommendation (LOR), scholarship, service commitment, interview performance, etc] perceived to be associated with entry into PCSM fellowship (1-10 scale; 10 = highest value). Weighted mean ± SD were calculated for each question. MAIN OUTCOME MEASURES: Determination of most valued factors for entry into PCSM fellowship. RESULTS: Responses were provided by 242/2332 (10.4%) of the American Medical Society for Sports Medicine members, including 77 of 175 (44%) FDs. The top 3 factors for entry into PCSM fellowships for all respondents were as follows: interview performance (9.17 ± 1.13), LOR from SM fellowship faculty (8.20 ± 1.67), and high school game/event coverage (7.83 ± 1.70). Musculoskeletal ultrasound experience (4.50 ± 2.23) and residency training in pediatrics (4.58 ± 2.54), internal medicine (4.48 ± 2.44), emergency medicine (4.44 ± 2.59), and physical medicine and rehabilitation (4.40 ± 2.83) received the lowest scores. CONCLUSIONS: Applicants seeking entry into SM fellowships should prioritize performance during interviews, LOR from SM fellowship faculty, and team game/event coverage experiences.

Patients often seek care from a family physician when they have a musculoskeletal injury or sport-related ailment. Family physicians must be adequately trained to provide this care. While general guidance is provided by the Accreditation Counsel for Graduate Medical Education (ACGME) it is left up to the individual programs to develop, implement, and execute their orthopedic and sports medicine curriculums. The American Academy of Family Physicians' (AAFP) Recommended Curriculum Guideline for Family Medicine Residents - Musculoskeletal and Sports Medicine provides a basic outline format for curriculum content and reference resources. The aim of this article is to elaborate on those training requirements and help programs to develop a curriculum implementation plan that will deliver a baseline level of competence for family medicine trainees.

Objectives: To evaluate the time taken and the mechanism through which the occlusion settles following the placement of a preformed metal crown (PMC) using the Hall technique. The secondary objective was to assess any temporo mandibular joint dysfunction (TMD) resulting from the Hall technique through a questionnaire. Study Design: 44 children fulfilling the inclusion criteria were evaluated for changes in overbite and occlusal vertical dimension (OVD) following the placement of preformed metal crowns (PMCs) using the Hall technique. The overbite and OVD measurements were taken before treatment, immediately post treatment, then at one, two, three and four weeks post treatment. After four weeks, a questionnaire recorded the occurrence of any signs or symptoms of TMD. Results: At the fourth week, the overbite measurement did not show a statistically significant difference (p value= 0.58) compared to baseline values indicating that the occlusion settled by the fourth week. By the third week the OVD values obtained did not show a significant difference compared to the baseline (p value= 0.42) indicating that the OVD had been restored. The questionnaire provided at the end of four weeks showed negative response for signs and symptoms of TMD in all the children. Conclusion: Any changes in occlusion following the placement of a Hall crown settles in four weeks. The OVD settles three weeks post placement implying that extrusion of teeth do not play a role in settling of the occlusion. The children do not develop any signs or symptoms of TMD post a Hall crown.

Laser-induced plasmas experience Stark broadening and shifts of spectral lines carrying spectral signatures of plasma properties. In this paper, we report time-resolved Stark broadening measurements of a nitrogen triplet emission line at 1-6 bar ambient pressure in a pure nitrogen cell. Electron densities are calculated using the Stark broadening for different pressure conditions, which are shown to linearly increase with pressure. Additionally, using a Boltzmann fit for the triplet, the electron temperature is calculated and shown to decrease with increasing pressure. The rate of plasma cooling is observed to increase with pressure. The reported Stark broadening based plasma diagnostics in nitrogen at high pressure conditions will be significantly useful for future studies on high-pressure combustion and detonation applications.
RESUMO
INTRODUCTION: Wernicke's encephalopathy (WE) is an acute neurologic syndrome resulting from a deficiency in thiamine, also known as Vitamin B1. Thiamine stores can be depleted rapidly in patients with severe hyperemesis. Treatment with thiamine typically results in complete resolution of the neurological abnormalities. CASE REPORT: A 15-year-old G2P0010 at 13.2 weeks gestation presented with altered mental status and transaminitis. She had a medical termination in her previous pregnancy following an admission for a similar clinical scenario. She was initially thought to have a postoperative surgical complication due to recent cholecystectomy, but further evaluation revealed thiamine depletion. Magnetic resonance imaging confirmed the diagnosis of WE. Repletion of thiamine and folic acid resulted in rapid clinical improvement. CONCLUSION: WE should be considered in the differential diagnosis of pregnant patients with hyperemesis and altered mental status. A prior history of WE increases the risk of recurrence during pregnancy. Severe hyperemesis during pregnancy increases the risk of thiamine deficiency and WE. Early thiamine supplementation may reduce the risk of WE in patients with a prior clinical history or in patients with severe hyperemesis gravidarum.
