RESUMO
INTRODUCTION: Malaria is a potentially fatal parasitic disease transmitted by the Anopheles mosquito. A resurgence in locally acquired infections has been reported in the U.S. OBJECTIVE: This narrative review provides a focused overview of malaria for the emergency clinician, including the epidemiology, presentation, diagnosis, and management of the disease. DISCUSSION: Malaria is caused by Plasmodium and is transmitted by the Anopheles mosquito. Disease severity can range from mild to severe. Malaria should be considered in any returning traveler from an endemic region, as well as those with unexplained cyclical, paroxysms of symptoms or unexplained fever. Patients most commonly present with fever and rigors but may also experience cough, myalgias, abdominal pain, fatigue, vomiting, and diarrhea. Hepatomegaly, splenomegaly, pallor, and jaundice are findings associated with malaria. Although less common, severe malaria is precipitated by microvascular obstruction with complications of anemia, acidosis, hypoglycemia, multiorgan failure, and cerebral malaria. Peripheral blood smears remain the gold standard for diagnosis, but rapid diagnostic tests are available. Treatment includes specialist consultation and antimalarial drugs tailored depending on chloroquine resistance, geographic region of travel, and patient comorbidities. Supportive care may be required, and patients with severe malaria will require resuscitation. Most patients will require admission for treatment and further monitoring. CONCLUSION: Emergency medicine clinicians should be aware of the presentation, diagnosis, evaluation, and management of malaria to ensure optimal outcomes.

In an experiment (N = 206) using skin cancer prevention messages and a 2 (mortality: salient, control) × 2 (freedom-limiting language: freedom-limiting, autonomy-supportive) independent-group design, we tested the terror management health model and integrated its predictions with the theory of psychological reactance. We used a sample of young adults because they are most at risk for excessive tanning. Consistent with the study predictions about proximal defenses, mortality salience significantly increased intentions to wear sunscreen all year around, relative to the control condition. A significant interaction between freedom-limiting language and mortality salience on behavioral intention to purchase high-SPF lotion revealed that, when a freedom-limiting message was paired with mortality salience, intentions to purchase high-SPF lotion were significantly greater as compared to autonomy-supportive language, indicating that mortality salience mitigated the maladaptive effects of reactance. These results add to a growing body of research identifying boundary conditions for reactance effects and, further, point to the utility of directive (albeit freedom-limiting language) in health-prevention messages attempting to communicate deadly health risks.
RESUMO
PURPOSE: The primary aim of this network meta-analysis (NMA) is to compare the incidence of venous thromboembolisms (VTE) and bleeding risk following the use of pharmacological and non-pharmacological thromboprophylaxis for arthroscopic knee surgery (AKS). This study assumed the null hypothesis which was that there will be no difference in the incidence of VTE and bleeding risk when comparing no treatment, pharmacological treatment, and non-pharmacological treatment for preventing VTE events following AKS. METHODS: A systematic electronic search of CENTRAL, Medline, Embase, and ClinicalTrials.gov was carried out. All English language prospective randomized clinical trials published from date of database inception to November 21, 2021 were eligible for inclusion. All papers addressing arthroscopic knee surgery were eligible for inclusion regardless of timing of surgery, operation, surgical technique, or rehabilitation. Multiple random effects NMAs were conducted to compare all treatments for each outcome. The primary outcome was the incidence of pulmonary embolism (PE) and secondary outcomes consisted of overall deep vein thrombosis (DVT), symptomatic DVT, asymptomatic DVT, and all-cause mortality. Adverse outcomes consisted of major and minor bleeding, as well as adverse events. RESULTS: A total of nine studies with 4526 patients were included for analysis. There were 1054 patients in the no treatment/placebo group (NT/Placebo), 1646 patients in the graduated compression stockings, 810 patients in the extended-duration (> 10 days) low molecular weight heparin (Ext-LMWH) group, 650 patients in the short-duration (< 10 days) LMWH group (Short-LMWH), and 356 patients in the rivaroxaban group. GCS, Ext-LMWH, Short-LMWH and rivaroxaban all demonstrated low risks of PE, symptomatic DVT, asymptomatic DVT, combined DVT and all-cause mortality. Similarly, all interventions demonstrated a low risk of major bleeding. CONCLUSION: There is no significant difference in the risk reduction of PEs, symptomatic DVTs, major/minor bleeding, and/or all-cause mortality when using LWMH (including short or extended regimens), rivaroxaban, graduated compression stockings or no treatment following arthroscopic knee surgery. Future primary research on the efficacy of thromboprophylaxis following arthroscopic knee surgery should stratify outcomes based on key patient (i.e., age, sex, comorbidities) and surgical (i.e., major vs. minor surgery) characteristics and should include acetylsalicylic acid as an intervention. LEVEL OF EVIDENCE: I, network meta-analysis of Level I studies.

BACKGROUND: Excision of bone tumors and endoprosthetic reconstruction allow patients early weightbearing and a potential functional advantage compared with amputation. These reconstructions do not restore the limb to normal status, however, and patients are subject to complications that may result in revision or loss of the limb. Because better understanding of these complications based on current information might help the patient and surgeon in decision-making, we undertook a systematic review of studies published on this topic. QUESTIONS/PURPOSES: (1) What are the primary modes and proportion of failure of tumor endoprostheses in patients undergoing reconstruction after excision of primary extremity bone sarcomas? METHODS: We systematically searched MEDLINE, Embase, and the Cochrane Library for all studies published from April 15, 1998, to April 15, 2018. Three reviewers independently reviewed studies reporting endoprosthetic reconstruction survival and events requiring revision for primary extremity bone tumors treated with endoprosthetic reconstruction for inclusion and performed independent data extraction. We excluded all studies with fewer than five patients, any systematic review/meta-analyses, and any study not reporting on primary extremity bone tumors. All discrepancies were resolved by the study's senior author. Data extracted from included studies were any reoperation event for wound dehiscence, any operative fixation for a pathologic fracture, and any revision of the primary endoprosthesis for implant wear or breakage, deep infection not amenable to prosthesis retention, or for local recurrence. We assessed the overall quality of the evidence with the Methodological Index for Non-Randomized Studies (MINORS) approach with a higher MINORS score representative of a more methodologically rigorous study with a total possible score of 16 points for noncomparative and 24 points for comparative studies. Forty-nine studies met criteria for inclusion from an initial search return of 904 studies, of which no studies were randomized controlled trials. From a total patient population of 2721, there was a mean followup of 93 months (range, 1-516 months) with loss to followup or death occurring in 447 of 2118 (21%) patients with six studies not providing loss to followup data. The mean MINORS score was 14 for prospective studies and 11 for retrospective studies. RESULTS: Overall, there were 1283 reoperations among the 2721 (47%) patients. Reoperation for mechanical endoprosthetic events (soft tissue dehiscence or periarticular soft tissue instability, aseptic loosening, or implant wear/fracture) occurred in 907 of 2721 (33%) patients. Aseptic loosening occurred at a mean of 75 months (range, 1-376 months) in 212 of 315 patients (67%). Deep infection requiring removal of the initial prosthesis occurred in 247 of 2721 (9%) patients with deep infection occurring at a mean of 24 months (range, 1-372 months) in the 190 infections (77%) with time to infection data available. Local recurrence rates requiring revision or amputation occurred in 129 (5%) of all patients. There was an overall primary endoprosthesis survival rate without any surgical reintervention of 63% among reporting studies at a mean of 79 months followup. CONCLUSIONS: Failures of endoprosthetic reconstructions after extremity tumor surgery are common, most often resulting from implant wear or fracture, aseptic loosening, and infection. Importantly, the aggregated data are the first to attempt to quantify the time to specific complication types within this patient population. Deep infection not amenable to endoprosthesis retention appears to occur approximately 2 years postoperatively in most patients, with aseptic loosening occurring most commonly at 75 months. Although endoprosthetic reconstruction is one of the most common forms of reconstruction after bone tumor resection, the quality of published evidence regarding this procedure is of low quality with high loss to followup and data quality limiting interstudy analysis. The quality of the evidence is low with high loss to followup and inconsistent reporting of times to reintervention events. Although the most common modes of endoprosthetic failure in this population are well known, creation of quality prospective, collaborative databases would assist in clarifying and informing important elements of the followup process for these patients. LEVEL OF EVIDENCE: Level IV, therapeutic study.

PURPOSE: This systematic review explored the indications, efficacy, and complications of hip arthroscopy in the setting of trauma. METHODS: Databases (PubMed, Medline, Embase, and Web of Science) were searched from database inception to March 2015 for studies using hip arthroscopy in trauma treatment. Systematic screening of eligible studies was undertaken in duplicate. The inclusion criteria included studies pertaining to arthroscopic intervention of all traumatic hip injuries. Abstracted data were organized in table format with descriptive statistics presented. RESULTS: From an initial search yield of 2,809 studies, 32 studies (25 case reports and 7 case series) satisfied the criteria for inclusion. A total of 144 patients (age range, 10 to 53 years) underwent hip arthroscopy for 6 indications associated with trauma: 8 patients for bullet extraction, 6 for femoral head fixation, 82 for loose body removal, 6 for acetabular fracture fixation, 20 for labral intervention, and 23 for ligamentum teres debridement. Patients were followed up postoperatively for a mean of 2.9 years (range, 8 days to 16 years). Successful surgery was achieved in 96% of patients. The rate of major complications (i.e., pulmonary embolism and abdominal compartment syndrome) was 1.4% (2 of 144); avascular necrosis, 1.4% (2 of 144); and nerve palsy, 0.7% (1 of 144). CONCLUSIONS: Hip arthroscopy appears effective and safe in the setting of trauma. These data should be interpreted with caution because of the low-quality evidence of the included studies. Surgeons should be aware of the potential complications such as abdominal compartment syndrome and thromboembolic events when performing hip arthroscopy in the setting of trauma. LEVEL OF EVIDENCE: Level IV, systematic review of Level IV studies.

PURPOSE: To evaluate the indications, preoperative workup outcomes, and postoperative rehabilitation of patients with femoroacetabular impingement (FAI) receiving microfracture as an adjunct to hip arthroscopy for chondral defects. METHODS: The electronic databases MEDLINE, EMBASE, and PubMed were searched and screened in duplicate for studies involving patients with FAI treated arthroscopically with microfracture of the hip for chondral defects either solely or as an adjunct to hip arthroscopy. Data regarding indications, investigations, outcomes, and postoperative rehabilitation were abstracted from eligible studies. The references of included studies were additionally searched, and descriptive statistics are provided. RESULTS: There were 12 studies included in this review, involving 267 patients. With the exception of a single, one-patient case report, 11 of the 12 studies reported positive outcomes after hip arthroscopy with microfracture. Only 0.7% of the total patients experienced a complication, and 1.1% required further surgery on the basis of outcomes evaluated at a mean follow-up of 29.5 (range, 4 to 60) months across the studies. Eight of 12 studies discussed the preoperative workup of these patients, with X-rays and magnetic resonance imaging being the most common preoperative imaging used. There was little reported on weight-bearing status during postoperative rehabilitation. CONCLUSIONS: The outcomes reported in the literature after hip arthroscopy with microfracture for chondral defects are, in general, positive, with a very low percentage of patients requiring further surgery or experiencing complications. The most common indication used in the literature for microfracture is a full-thickness, focal chondral defect (Outerbridge grade IV). The vast majority of literature recommends limited weight bearing after microfracture; however, there was significant variation among the specific rehabilitation protocols used. More research is needed to explore what indications and postoperative rehabilitation result in the best outcomes for patients. LEVEL OF EVIDENCE: Level IV, systematic review of Level II, III, and IV studies.

PURPOSE: Surgical hip dislocation (SHD) and hip arthroscopy are surgical methods used to correct deformity associated with femoroacetabular impingement (FAI). Though both of these approaches appear to benefit patients, no studies exist comparing healthcare resource utilization of the two surgical approaches. This systematic review examines the literature and the records of two surgeons to evaluate the resource utilization associated with treating symptomatic FAI via these two methods. METHODS: EMBASE, MEDLINE and PubMed were searched for relevant articles. The articles were systematically screened, and data was abstracted in duplicate. To further supplement resource utilization data, a retrospective chart review of two surgeon's patient data (one using SHD and another using an arthroscopic approach) was completed. Experts in pharmacy, physiotherapy, radiology, anaesthesia, physiatry and the local hospital finance department were also consulted. RESULTS: There were 52 studies included with a total of 460 patients (535 hips) and 3886 patients (4147 hips) who underwent SHD and arthroscopic surgery for FAI, respectively. Regardless of approach, most patients treated for symptomatic FAI improved across various outcomes measures with low complication rates. Surgical time across all approaches was similar, averaging 118 ± 2 min. On a per patient basis, hip arthroscopy ($10,976) uses approximately 41 % of the resources of SHD ($24,379). CONCLUSION: There were no significant differences in outcomes for FAI treated with SHD or arthroscopy. However, with regard to healthcare resource utilization based on the OHIP healthcare system, hip arthroscopy uses substantially less resources than SHD within the first post-operative year. LEVEL OF EVIDENCE: Systematic Review of Level IV Studies, Level IV.

We report the design of a targeted resequencing panel for monogenic dyslipidemias, LipidSeq, for the purpose of replacing Sanger sequencing in the clinical detection of dyslipidemia-causing variants. We also evaluate the performance of the LipidSeq approach versus Sanger sequencing in 84 patients with a range of phenotypes including extreme blood lipid concentrations as well as additional dyslipidemias and related metabolic disorders. The panel performs well, with high concordance (95.2%) in samples with known mutations based on Sanger sequencing and a high detection rate (57.9%) of mutations likely to be causative for disease in samples not previously sequenced. Clinical implementation of LipidSeq has the potential to aid in the molecular diagnosis of patients with monogenic dyslipidemias with a high degree of speed and accuracy and at lower cost than either Sanger sequencing or whole exome sequencing. Furthermore, LipidSeq will help to provide a more focused picture of monogenic and polygenic contributors that underlie dyslipidemia while excluding the discovery of incidental pathogenic clinically actionable variants in nonmetabolism-related genes, such as oncogenes, that would otherwise be identified by a whole exome approach, thus minimizing potential ethical issues.

PURPOSE: Synovial chondromatosis of the hip is a benign condition whereby pain and functional limitations occur due to numerous intra-articular osteochondral fragments produced by a metaplastic synovium. Recurrence not only worsens morbidity but may lead to malignant transformation. With reported recurrence rates as high as 22% by open surgical approaches and given the increasing use of hip arthroscopy for the treatment of synovial chondromatosis, we sought to quantify the recurrence rate after arthroscopy, as well as identify predisposing factors for recurrence. METHODS: Using predetermined inclusion criteria, 3 electronic databases--Embase, Medline, and PubMed-were searched for relevant articles addressing arthroscopic surgery for synovial chondromatosis of the hip across all available dates up to and including February 16, 2014. A hand search of the reference sections of the included studies was also completed. Article screening was conducted in duplicate. Reviewer agreement statistics and descriptive statistics of the included studies are presented. RESULTS: From an initial retrieval of 2,542 studies, 14 studies satisfied the criteria for inclusion. A total of 197 patients (age range, 13 to 81 years) underwent hip arthroscopy for removal of intra-articular osteochondral fragments and synovectomy to alleviate both mechanical symptoms and pain. Follow-up periods ranged from 1 to 184 months, with approximately 7.6% of patients (15 of 197) lost to follow-up. The recurrence rate after hip arthroscopy was 7.1% (14 of 197), and the rate of minor complications, such as perineal and pedal neurapraxia, was 1%. CONCLUSIONS: For synovial chondromatosis of the hip, arthroscopic removal of osteochondral fragments with synovectomy is both safe and effective, with a mean recurrence rate of 7.1%. LEVEL OF EVIDENCE: Level IV, systematic review of Level IV studies.

The value of research articles is increasingly contingent on complex data analysis results which substantiate their claims. Compared to data production, data analysis more readily lends itself to a higher standard of transparency and repeated operator-independent execution. This higher standard can be approached via fully reexecutable research outputs, which contain the entire instruction set for automatic end-to-end generation of an entire article from the earliest feasible provenance point. In this study, we make use of a peer-reviewed neuroimaging article which provides complete but fragile reexecution instructions, as a starting point to draft a new reexecution system which is both robust and portable. We render this system modular as a core design aspect, so that reexecutable article code, data, and environment specifications could potentially be substituted or adapted. In conjunction with this system, which forms the demonstrative product of this study, we detail the core challenges with full article reexecution and specify a number of best practices which permitted us to mitigate them. We further show how the capabilities of our system can subsequently be used to provide reproducibility assessments, both via simple statistical metrics and by visually highlighting divergent elements for human inspection. We argue that fully reexecutable articles are thus a feasible best practice, which can greatly enhance the understanding of data analysis variability and the trust in results. Lastly, we comment at length on the outlook for reexecutable research outputs and encourage re-use and derivation of the system produced herein.
RESUMO
INTRODUCTION: The US military is transitioning into a posture preparing for large-scale combat operations in which delays in evacuation may become common. It remains unclear which casualty population can have their initial surgical interventions delayed, thus reducing the evacuation demands. METHODS: We performed a secondary analysis of a previously described dataset from the Department of Defense Trauma Registry (DODTR) focused on casualties who received prehospital care. In this, we sought to determine (1) of those who underwent operative intervention, the proportion of surgeries occurring ≥3 days post-injury, and (2) of those who underwent early versus delayed surgery, the proportions who required blood products. RESULTS: There were 6,558 US military casualties who underwent surgical intervention-6,224 early (less than 3 days from injury) and 333 delayed (≥ 3 days from injury). The median Injury Severity Score (ISS) was higher in the early cohort (10 versus 6, p is less than 0.001). Serious injuries to the head were more common in the early cohort (12% versus 5%, p is less than 0.001), as were the thorax (13% versus 9%, p=0.041), abdomen (10% versus 5%, p=0.001), extremities (37% versus 14%, p is less than 0.001), and skin (4% versus less than 1%, p=0.001). Survival to discharge was lower in the early cohort (97% versus 100%, p is less than 0.001). Mean whole blood consumption was higher in the early cohort (0.5 versus 0 units, p is less than 0.001), as was packed red blood cells (6.3 versus 0.5, p is less than 0.001), platelets (0.9 versus 0, p is less than 0.001), and fresh frozen plasma (4.5 versus 0.2, p is less than 0.001). The administration of any units of packed red blood cells and whole blood was higher for the early cohort (37% versus 7%, p is less than 0.001), as was a ≥3 units threshold (30% versus 3%, p is less than 0.001), and ≥10 units threshold (18% versus 1%, p is less than 0.001). CONCLUSIONS: Few combat casualties underwent delayed surgical interventions defined as ≥3 days post injury, and only a small number of casualties with delayed surgical intervention received blood products. Casualties who received early surgical intervention were more likely to have higher injury severity scores, and more likely to receive blood.

Neuroimaging research faces a crisis of reproducibility. With massive sample sizes and greater data complexity, this problem becomes more acute. Software that operates on imaging data defined using the Brain Imaging Data Structure (BIDS) - BIDS Apps - have provided a substantial advance. However, even using BIDS Apps, a full audit trail of data processing is a necessary prerequisite for fully reproducible research. Obtaining a faithful record of the audit trail is challenging - especially for large datasets. Recently, the FAIRly big framework was introduced as a way to facilitate reproducible processing of large-scale data by leveraging DataLad - a version control system for data management. However, the current implementation of this framework was more of a proof of concept, and could not be immediately reused by other investigators for different use cases. Here we introduce the BIDS App Bootstrap (BABS), a user-friendly and generalizable Python package for reproducible image processing at scale. BABS facilitates the reproducible application of BIDS Apps to large-scale datasets. Leveraging DataLad and the FAIRly big framework, BABS tracks the full audit trail of data processing in a scalable way by automatically preparing all scripts necessary for data processing and version tracking on high performance computing (HPC) systems. Currently, BABS supports jobs submissions and audits on Sun Grid Engine (SGE) and Slurm HPCs with a parsimonious set of programs. To demonstrate its scalability, we applied BABS to data from the Healthy Brain Network (HBN; n=2,565). Taken together, BABS allows reproducible and scalable image processing and is broadly extensible via an open-source development model.
RESUMO
Tibial tubercle avulsion fracture with simultaneous patellar tendon avulsion is a rare injury that has only ever been reported in adolescents; the diagnosis and management of this combined lesion has not been described in the adult population. A healthy 62-year-old male presented with acute knee pain and an inability to walk after a fall on ice. Radiographs demonstrated a displaced fracture of the tibial tubercle; patellar tendon integrity could not be verified by ultrasonography. Intraoperatively, the patient was found to have a distal avulsion of the patellar tendon in addition to tubercle fracture. First, the tendon was secured to the tubercle fragment with transosseous sutures. A novel slotted-plate construct was used to fix the tubercle fragment prior to tightening the sutures. Postoperatively, the patient was permitted to bear weight as tolerated with the operative knee immobilized in extension. After six weeks, knee range of motion was gradually increased using a hinged brace. At one year, the patient had achieved excellent range of motion (full extension to 135 degrees of flexion) and strength (5/5 knee flexion and extension) without residual pain or complications. This case represents the first description of diagnosis, management, and rehabilitation of a combined tibial tubercle fracture with distal patellar tendon avulsion in an adult. The unique construct, a slotted-plate over transosseous sutures, provided excellent results and likely has further applications.
RESUMO
CONTEXT: The opioid epidemic has been well-documented in the general population, but the literature pertaining to opioid use and misuse in the athletic population remains limited. OBJECTIVES: The objectives of this study were to seek answers to the following questions: (1) what are the rates of opioid use and misuse among athletes, (2) do these rates differ compared with the nonathletic population, and (3) are there specific subgroups of the athletic population (eg, based on sport, level of play) who may be at higher risk? DATA SOURCES: The Embase, MEDLINE, and PubMed were used for the literature search. STUDY SELECTION: Records were screened in duplicate for studies reporting rates of opioid use among athletes. All study designs were included. STUDY DESIGN: Systematic review. LEVEL OF EVIDENCE: Level 4. DATA EXTRACTION: Data regarding rates of opioid use, medication types, prescription patterns, and predictors of future opioid use were collected. Study quality was assessed using the Methodological Index for Non-Randomized Studies (MINORS) criteria for clinical studies and 5 key domains previously identified for survey studies. RESULTS: A total of 11 studies were eligible for inclusion (N = 226,256 athletes). Studies included survey studies and retrospective observational designs. Opioid use among professional athletes at any given time, as reported in 2 different studies, ranged from 4.4% to 4.7%, while opioid use over a National Football League career was 52%. High school athletes had lifetime opioid use rates of 28% to 46%. Risk factors associated with opioid use included Caucasian race, contact sports (hockey, football, wrestling), postretirement unemployment, and undiagnosed concussion. Use of opioids while playing predicted use of opioids in retirement. CONCLUSION: Overall, opioid use is prevalent among athletes, and use during a playing career predicts postretirement use. This issue exists even at the high school level, with similar rates to professional athletes. Further higher quality observational studies are needed to better define patterns of opioid use in athletes.

The purpose of this study was to identify the causes and risk factors for hip fractures, a rare but devastating complication, following hip arthroscopy. The electronic databases MEDLINE, EMBASE and PubMed were searched and screened in duplicate for relevant clinical and basic sciences studies and pertinent data was abstracted and analysed in Microsoft Excel. Nineteen studies (12 clinical studies and seven biomechanical studies) with a total of 31 392 patients experiencing 43 hip fractures (0.1% of patients) met the inclusion criteria for this systematic review. Femoral osteochondroplasty was performed in 100% of patients who sustained a hip fracture. Six of the 12 (50%) studies identified early weight bearing (prior to 6 weeks post-operatively) as the cause for the hip fracture. Other causes of this complication included over resection during femoral osteochondroplasty, minor trauma and intensive exercise. The results suggest that early weight bearing is the largest modifiable risk factor for hip fracture after femoral osteochondroplasty. For this reason, an extended period of non-weight bearing or restricted weight bearing should be considered in select patients. Studies report a correlation between risk for post-operative hip fracture and increased age. Increased resection during osteochondroplasty has been correlated with increased risk of fracture in various basic science studies. Resection depth has significantly higher impact on risk of fracture than resection length or width. The reported amounts of resection that depth that can be performed before there is a significantly increased risk of fracture of the femoral neck varies from 10 to 30%.
