RESUMO

BACKGROUND: Orthopedic residency and fellowship applicants with a strong research record are highly valued for their potential in continuing academic excellence. Despite this, the association between research productivity during training and future academic productivity as an attending orthopedic surgeon is not well-established. We assess the effects of research output during different periods of surgical training as well as residency location on long-term academic productivity as an attending shoulder and elbow surgeon. METHODS: A search of the 2022-2023 American Shoulder and Elbow Surgeons (ASES) Fellowship Directory was conducted to identify a list of orthopedic shoulder and elbow fellowship faculty members. Each surgeon's residency, fellowship and current institution of practice were determined and stratified by geographic location. Total publication counts acquired before residency, during residency, during fellowship, and after fellowship were collected for each faculty member. Attending publication rates and H-indices were calculated. A multivariate linear regression model was created, and significance was set at a P-value < 0.05. RESULTS: A total of 149 shoulder and elbow fellowship faculty members representing 34 fellowship programs were identified. The average number of total publications per surgeon was 88.8 ± 102. The average attending publication rate was 5.29 ± 6.89 publications per year. The average H-index for included surgeons was 27.8 ± 24.4. The number of publications acquired before residency (ß = 0.293; P < 0.001), during residency (ß = 0.110; P = 0.025) and during fellowship (ß = 0.593; P < 0.001) were significantly associated with an increased attending publication rate, but no association was observed with the H-index [before residency (ß = -0.221; P = 0.574), during residency (ß = 0.045; P = 0.866), during fellowship (ß = 0.198; P = 0.678)]. There were no significant differences in total publication count (P = 0.397), attending publication rate (P = 0.237), or H-index (P = 0.364) based on location of residency training. DISCUSSION: Research output before and during surgical training is predictive of continued academic productivity as a shoulder and elbow surgeon. In particular, greater productivity during surgical fellowship was most predictive of academic output as an attending. While long-term academic productivity does not seem to be influenced by the geographic location of residency training, attending surgeons practicing in the Midwest had significantly greater total publication counts and H-indices but similar annual publication rates. LEVEL OF EVIDENCE: Survey Study; Cross Sectional Design; Literature and Internet Sources.

RESUMO

BACKGROUND: Recurrent anterior shoulder instability remains the most common complication from a prior shoulder dislocation, especially among young and active individuals who engage in athletic activities. This instability can lead to repeated subluxation or dislocations of the humeral head from the glenoid fossa. The purpose of this study is to compare postoperative recurrence rates, instability-related revision and return to sport (RTS) rates between isolated arthroscopic Bankart repair (ABR) and ABR with remplissage (ABR + R) for anterior shoulder instability with subcritical glenoid bone loss (GBL) and a Hill-Sachs lesion (HSL). METHODS: PubMed, Embase, and Web of Science were searched on June 2022. Studies sought were those comparing postoperative outcomes of ABR + R versus isolated ABR for subcritical GBL and an HSL. Study quality was evaluated using the revised Cochrane tool. Redislocations, instability-related revisions, and RTS rates were extracted and pooled estimates were calculated using the random-effect model. RESULTS: Twelve studies were included with a mean follow-up of 48.2 months for isolated ABR and 43.2 months for ABR + R. The meta-analytic comparison demonstrated that ABR + R resulted in statistically significant improvement in Rowe and American Shoulder and Elbow Surgeons scores by 6.5 and 2.2 points, respectively; however, the improvements in patient-reported outcomes were not clinically meaningful. ABR + R resulted in reduced external rotation at the side by 1° which was not clinically meaningful and there was no significant difference in terms of forward elevation. ABR + R resulted in a statistically significant reduction of overall postoperative recurrences (odds ratio [OR]: 9.36), postoperative dislocations (OR: 6.28), instability-related revision (OR: 3.46), and RTS to any level (OR: 2.85). CONCLUSION: The addition of remplissage to ABR for recurrent anterior shoulder instability with subcritical GBL and HSL results in significantly lower postoperative instability recurrence, lower instability-related revisions, and higher RTS to any level.

RESUMO

BACKGROUND: Understanding the role of social determinants of health disparities (SDHDs) in surgical outcomes can better prepare providers to improve postoperative care. In this study, we use International Classification of Diseases (ICD) codes to identify SDHDs and investigate the risk of postoperative complication rates among patients undergoing total shoulder arthroplasty (TSA). METHODS: A retrospective cohort analysis was conducted using a national insurance claims database. Using ICD and Current Procedural Terminology (CPT) codes, patients who underwent primary TSA with at least 2 years of follow-up in the database were identified. Patients with a history of SDHDs were identified using appropriate ICD-9 and ICD-10 codes. Patients were grouped in one of 2 cohorts: (1) patients with no history of SDHDs (control) and (2) patients with a history of SDHDs (SDHD group) prior to TSA. The SDHD and control groups were matched 1:1 for comorbidities and demographics prior to conducting multivariable analysis for 90-day medical complications and 2-year surgical complications. RESULTS: After matching, there were 8023 patients in the SDHD group and 8023 patients in the control group. The SDHD group had significantly higher odds for 90-day medical complications including heart failure, cerebrovascular accident, renal failure, deep vein thrombosis, pneumonia, sepsis, and urinary tract infection. Additionally, the SDHD group had significantly higher odds for revision surgery within 2 years following TSA. Patients in the SDHD group also had a significantly longer length of hospital stay following TSA. DISCUSSION: This study highlights the association between SDHDs and postoperative complications following TSA. Quantifying the risk of complications and differences in length of stay for TSA patients with a history of SDHDs is important in determining value-based payment models and risk stratifying to optimize patient care.

RESUMO

Orthopedic surgeons commonly perform corticosteroid injections. These injections have systemic side effects, including suppression of the hypothalamic-pituitary adrenal axis. Due to this suppression, there is a theoretical risk of corticosteroid injections affecting the efficacy of the novel COVID-19 vaccines. This potential interaction led the American Academy of Orthopedic Surgeons to recommend, "avoiding musculoskeletal corticosteroid injections for two weeks before and one week after COVID vaccine administration." This review examines the literature underlying this recommendation. An extensive literature review was performed through PubMed, MEDLINE, and Google Scholar from database inception to May 2022. Keywords searched were COVID, coronavirus, vaccine, vaccination, steroids, and corticosteroids. Search results included articles written in the English language and encompassed reviews, case series, empirical studies, and basic science articles. There is no definitive evidence that corticosteroid injections affect COVID-19 vaccine efficacy or increase the risk of contracting COVID. The authors recommend orthopedic surgeons follow the AAOS guidelines, which recommend avoiding injections two weeks before and one week following COVID vaccine administration. Additional research is needed to better define this theoretical risk, especially since there is good evidence that injections suppress the hypothalamic-pituitary-adrenal-axis.

RESUMO

Hypothesis: The management of superior labrum anterior to posterior (SLAP) tears typically consists of either repair or biceps tenodesis (BT). While repair is more frequently recommended in younger patients, patients older than 40 years are often treated with BT. The purpose of this study is to determine whether there has been a change in utilization of these procedures over the past decade with respect to patient age as well as compare reoperation rates between the two procedures. Methods: The Pearldiver database was queried to identify BT and SLAP repairs indicated for SLAP tears performed from 2010 to 2019. The primary outcome was utilization rate, stratified by age. A secondary outcome was 2-year shoulder reoperation rates. Trends were reported in terms of compounded annual growth rate. Outcome analysis was conducted using univariate and multivariable analysis. Results: From 2010 to 2019, SLAP repair was the most common procedure performed for SLAP tears. Regardless of age, BT performed for SLAP tear had a significantly increased utilization rate; whereas, SLAP repair had a significantly decreased utilization rate. SLAP repair was more commonly performed in younger patients compared to BT. Following multivariable analysis, patients who underwent SLAP repair had significantly higher odds (odds ratio (OR): 1.453; 95% confidence interval (CI): 1.26-1.68; P < .001) of requiring an arthroscopic reoperation within 2 years when compared to those who underwent BT with no significant difference with respect to 2-year open reoperation. Conclusion: Although SLAP repair is still more commonly used to treat SLAP tears than BT, especially for younger patients, the utilization of SLAP repair is decreasing while BT is increasing. The increased utilization of BT may be associated with lower rates of shoulder reoperation for problematic SLAP tears.

RESUMO

Cleavage of the flavivirus premembrane (prM) structural protein during maturation can be inefficient. The contribution of partially mature flavivirus virions that retain uncleaved prM to pathogenesis during primary infection is unknown. To investigate this question, we characterized the functional properties of newly-generated dengue virus (DENV) prM-reactive monoclonal antibodies (mAbs) in vitro and using a mouse model of DENV disease. Anti-prM mAbs neutralized DENV infection in a virion maturation state-dependent manner. Alanine scanning mutagenesis and cryoelectron microscopy of anti-prM mAbs in complex with immature DENV defined two modes of attachment to a single antigenic site. In vivo, passive transfer of intact anti-prM mAbs resulted in an antibody-dependent enhancement of disease. However, protection against DENV-induced lethality was observed when the transferred mAbs were genetically modified to inhibit their ability to interact with Fcγ receptors. These data establish that in addition to mature forms of the virus, partially mature infectious prM+ virions can also contribute to pathogenesis during primary DENV infections.

RESUMO

BACKGROUND: Patients today have access to an increasing number of health resources to guide medical decision making, including specialist health care providers, the Internet, friends, and family members. No prior studies, to our knowledge, have comprehensively explored health information-seeking behavior (HISB) for patients being managed for shoulder pain. OBJECTIVE: Our primary objective is to identify which health resources patients use and find helpful in a cohort of patients being either evaluated or managed for shoulder pain. With increased access to the Internet and its use, we also hope to quantify the extent of use of Internet resources and identify predictors of patient use. METHODS: We interviewed a cohort of new and follow-up patients being surgically or nonoperatively managed for shoulder pain by a single fellowship-trained orthopedic surgeon. All patients were administered a questionnaire to determine HISB, which evaluated the types of resources used and those deemed most helpful in guiding medical decision making. For patients using the Internet, specific websites were documented. Additional variables that were collected included age, gender, ethnicity, and highest education attained. Multivariable logistic regression was used to evaluate predictors of Internet use. RESULTS: This study included 242 patients. A discussion with an orthopedic surgeon was reported to be the most informative for nonoperatively treated patients, first postoperative patients, and operative follow-up patients. Patients at the first postoperative visit reported YouTube as their preferred resource almost 4 times more than new patients (odds ratio [OR] 3.9, P = .015). Search engine use was significantly higher in patients at the first postoperative visit (OR 5.8, P = .004) and patients at subsequent surgical follow-up (OR 8.3, P = .001) compared with new patients. Having an undergraduate (OR 0.1, P = .037) or graduate degree (OR 0.03, P = .01) had a significant inverse association with difficulty of using Internet resources. Patients of Black race reported significantly higher rates of distrust for Internet resources than those of White race (OR 5.8, P < .001). CONCLUSION: This study highlights the patterns of HISB among patients with shoulder conditions. A face-to-face discussion with a physician or a shoulder surgeon was the most crucial resource for information compared to other resources. This study has also defined the preferred Internet resources for patients at different time points of care and the reasons for refraining from seeking health information on the Internet. Such findings can aid shoulder surgeons in understanding the optimal methods for delivering health information for different patient demographics and different phases of their care.

RESUMO

AIM: There is a requirement for an expansive and up to date review of the management of emergency colorectal conditions seen in adults. The primary objective is to provide detailed evidence-based guidelines for the target audience of general and colorectal surgeons who are responsible for an adult population and who practise in Great Britain and Ireland. METHODS: Surgeons who are elected members of the Association of Coloproctology of Great Britain and Ireland Emergency Surgery Subcommittee were invited to contribute various sections to the guidelines. They were directed to produce a pathology-based document using literature searches that were systematic, comprehensible, transparent and reproducible. Levels of evidence were graded. Each author was asked to provide a set of recommendations which were evidence-based and unambiguous. These recommendations were submitted to the whole guideline group and scored. They were then refined and submitted to a second vote. Only those that achieved >80% consensus at level 5 (strongly agree) or level 4 (agree) after two votes were included in the guidelines. RESULTS: All aspects of care (excluding abdominal trauma) for emergency colorectal conditions have been included along with 122 recommendations for management. CONCLUSION: These guidelines provide an up to date and evidence-based summary of the current surgical knowledge in the management of emergency colorectal conditions and should serve as practical text for clinicians managing colorectal conditions in the emergency setting.

RESUMO

Zika virus (ZIKV) is a major human pathogen and member of the Flavivirus genus in the Flaviviridae family. In contrast to most other insect-transmitted flaviviruses, ZIKV also can be transmitted sexually and from mother to fetus in humans. During recent outbreaks, ZIKV infections have been linked to microcephaly, congenital disease, and Guillain-Barré syndrome. Neutralizing antibodies have potential as therapeutic agents. We report here a 4-Å-resolution cryo-electron microscopy structure of the ZIKV virion in complex with Fab fragments of the potently neutralizing human monoclonal antibody ZIKV-195. The footprint of the ZIKV-195 Fab fragment expands across two adjacent envelope (E) protein protomers. ZIKV neutralization by this antibody is presumably accomplished by cross-linking the E proteins, which likely prevents formation of E protein trimers required for fusion of the viral and cellular membranes. A single dose of ZIKV-195 administered 5 days after virus inoculation showed marked protection against lethality in a stringent mouse model of infection.

RESUMO

Curcumin, the main constituent of turmeric, is suspected to possess cancer chemopreventive properties. Pharmacokinetic and pharmacodynamic parameters have been reported, but few data exist describing whether methodologies are suitably robust for curcuminoid detection in colonic biopsy specimens. Information on the acceptability of prolonged administration of daily curcumin is not available. This is of vital importance to implement chemoprevention strategies. This study aimed to quantify levels of curcuminoids in colorectal mucosa of patients undergoing colorectal endoscopy or surgical resection and to obtain information on the acceptability and compliance with daily curcumin. Curcumin C3 complex (2.35 g) was administered to patients once daily for 14 days before endoscopic biopsy or colonic resection. Safety and tolerance were monitored. Analysis of curcuminoids in plasma, urine, and colonic mucosa was conducted by ultraperformance liquid chromatography (UPLC)-UV with characterization by liquid chromatography/tandem mass spectrometry (LC/MS-MS). Twenty-four of 26 patients commencing curcumin completed the course. Six patients reported mild gastrointestinal adverse events. Curcuminoids were detectable in nine of 24 plasma samples, 24 of 24 urine samples, and in the colonic mucosa of all 23 biopsied participants. Mean tissue levels were 48.4 µg/g (127.8 nmol/g) of parent curcuminoids. The major conjugate, curcumin glucuronide, was detectable in 29 of 35 biopsies. High levels of topical curcumin persisted in the mucosa for up to 40 hours postadministration. Sixteen participants (67%) stated that they would take curcumin long-term should it be of proven benefit. In summary, pharmacologically active levels of curcumin were recovered from colonic mucosa. The regimen used here seems safe, and patients support its use in long-term trials.

RESUMO

Resveratrol is a phytochemical with chemopreventive activity in preclinical rodent models of colorectal carcinogenesis. Antiproliferation is one of the many chemopreventive modes of action it has been shown to engage in. Concentrations of resveratrol, which can be achieved in human tissues after p.o. administration, have not yet been defined. The purpose of this study was to measure concentrations of resveratrol and its metabolites in the colorectal tissue of humans who ingested resveratrol. Twenty patients with histologically confirmed colorectal cancer consumed eight daily doses of resveratrol at 0.5 or 1.0 g before surgical resection. Resveratrol was found to be well tolerated. Normal and malignant biopsy tissue samples were obtained before dosing. Parent compound plus its metabolites resveratrol-3-O-glucuronide, resveratrol-4'-O-glucuronide, resveratrol-3-O-sulfate, resveratrol-4'-O-sulfate, resveratrol sulfate glucuronide, and resveratrol disulfate were identified by high-performance liquid chromatography (HPLC) with UV or mass spectrometric detection in colorectal resection tissue. Quantitation was achieved by HPLC/UV. Cell proliferation, as reflected by Ki-67 staining, was compared in preintervention and postintervention tissue samples. Resveratrol and resveratrol-3-O-glucuronide were recovered from tissues at maximal mean concentrations of 674 and 86.0 nmol/g, respectively. Levels of resveratrol and its metabolites were consistently higher in tissues originating in the right side of the colon compared with the left. Consumption of resveratrol reduced tumor cell proliferation by 5% (P = 0.05). The results suggest that daily p.o. doses of resveratrol at 0.5 or 1.0 g produce levels in the human gastrointestinal tract of an order of magnitude sufficient to elicit anticarcinogenic effects. Resveratrol merits further clinical evaluation as a potential colorectal cancer chemopreventive agent.
