Lipid droplets modulate proteostasis, SQST-1/SQSTM1 dynamics, and lifespan in C. elegans.

In several long-lived Caenorhabditis elegans strains, such as insulin/IGF-1 receptor daf-2 mutants, enhanced proteostatic mechanisms are accompanied by elevated intestinal lipid stores, but their role in longevity is unclear. Here, while determining the regulatory network of the selective autophagy receptor SQST-1/SQSTM1, we uncovered an important role for lipid droplets in proteostasis and longevity. Using genome-wide RNAi screening, we identified several SQST-1 modulators, including lipid droplets-associated and aggregation-prone proteins. Expansion of intestinal lipid droplets by silencing the conserved cytosolic triacylglycerol lipase gene atgl-1/ATGL enhanced autophagy, and extended lifespan. Notably, a substantial amount of ubiquitinated proteins were found on lipid droplets. Reducing lipid droplet levels exacerbated the proteostatic collapse when autophagy or proteasome function was compromised, and significantly reduced the lifespan of long-lived daf-2 animals. Altogether, our study uncovered a key role for lipid droplets in C. elegans as a proteostatic mediator that modulates ubiquitinated protein accumulation, facilitates autophagy, and promotes longevity.

Optimizing Orthopaedic Trauma Implant Pricing Through a Data-Driven and Surgeon-Integrated Approach.

OBJECTIVE: To determine whether market-based pricing could be coupled with surgeon integration into negotiation strategies to achieve lower pricing levels for orthopaedic trauma implants. A secondary aim was to identify specific types of implants that may offer larger opportunities for cost savings. METHODS: Market pricing levels were reviewed from 2 industry implant databases. This information was used by surgeons and supply chain management at our institution to select appropriate target pricing levels (25th percentile) for commonly used orthopaedic trauma implants. Target price values were provided to the existing 12 vendors used by our institution with a clear expectation that vendors meet these thresholds. RESULTS: Benchmark modeling projected a potential savings of 20.0% over our prior annual spend on trauma implants. After 2 rounds of negotiation, savings amounted to 23.0% of prior annual spend. Total savings exceeded 1,000,000 USD with 11 of 12 vendors (91.7%) offering net savings. Total percent savings were highest for external fixators, drill bits, and K-wires. Plates and screws comprised the greatest proportion of our prior annual spend and achieved similar savings. CONCLUSION: A surgeon and supply chain coordinated effort led to major cost savings without a need for consolidation of vendors. LEVEL OF EVIDENCE: Economic Level IV.

Comparison of endoscopic sinus surgery timing in lung transplant patients with cystic fibrosis.

BACKGROUND: No studies have investigated when endoscopic sinus surgery (ESS) is best performed in lung transplant patients with cystic fibrosis (CF). We sought to examine the effects of ESS timing on pulmonary health in this population. METHODS: A retrospective review of all adult lung transplant patients with CF who underwent ESS at our academic medical center over a near 25-year period was performed. Patients were split into two groups based on median time from lung transplantation to ESS. Twenty-three patients were included (12 ESS early and 11 ESS delayed). Outcomes included changes in pulmonary function tests (PFTs) from baseline, preoperative to postoperative measurements, the number and duration of hospitalizations for pulmonary exacerbations, and the number of antibiotic courses used specifically to treat pulmonary exacerbations during the 12 months before and after ESS. RESULTS: Baseline demographics, operative history, and pulmonary function characteristics were similar between groups. While the ESS early group saw significant improvement from preoperative percent-predicted FEV1 (ppFEV1 ) at 12 months postoperatively (confidence interval [CI]: 0.729-11.452, p = 0.030), there were no significant postoperative PFT changes for the ESS delayed group. Postoperative improvement in FEV1 and ppFEV1 at 12 months was significantly higher for the ESS early group relative to the ESS delayed group (CI: 0.010-0.583, p = 0.043; CI: 1.240-16.692, p = 0.025; respectively). The ESS early group had a significant reduction in the need for total antibiotic courses compared with the ESS delayed group (ESS early median: -1, interquartile range [IQR]: -1.5 to -0.5 vs. ESS delayed median: 0, IQR: 0 to 0; p = 0.027). CONCLUSION: Earlier ESS interventions following lung transplantation may improve pulmonary function and attenuate pulmonary exacerbations in CF patients.

The Fifth Metatarsal Shaft Fracture Is Well Treated With Benign Neglect.

Background. Spiral fifth metatarsal fractures have been studied previously in professional dancers. However, little has been reported about outcomes of these injuries in the general population. The objective of this study was to examine patient demographics of those who sustain this injury and their functional outcomes, as stratified by treatment type. Methods. A total of 186 "nonprofessional dancer" patients with a fifth metatarsal fracture who were treated by one orthopaedic surgeon at our academic medical center were identified through chart review. All patients were allowed to weight bearing as tolerated (WBAT). Time to healing, persistence of pain, range of motion, and complications were recorded. Independent samples t tests, 1-way analysis of variance, and Fisher exact tests were used for analysis. Results. Thirty-seven of the 186 patients with fifth metatarsal fractures reviewed were identified as having a spiral fifth metatarsal fracture with appropriate follow-up. The cohort was 78.4% female with a mean age of 50.3 years. Twenty-two were initially treated in a controlled ankle motion (CAM) boot, 14 in a postoperative shoe, and 1 continued in their own shoes. All patients were allowed to WBAT. All fractures healed by a mean of 3.1 months. By the end of the follow-up period, 67.6% of patients had full range of ankle motion, with 5.4% reporting feeling stiff, 27.0% reporting mild persistent pain, and 2.7% reporting significant persistent pain. Conclusion. Fifth metatarsal shaft ("Dancer's") fractures occur within the general population, not only among professional dancers. Without operative fixation and regardless of nonoperative treatment selected, these fractures heal reliably and do so without clinically relevant complication.Level of Evidence: Level III: Retrospective comparative study.

Some outcomes of patients treated operatively for distal humerus fractures are affected by hand dominance.

PURPOSE: This study sought to compare postoperative outcomes and complications between patients with distal humerus fractures treated with open reduction and internal fixation (ORIF) of their non-dominant versus dominant arm. METHODS: A retrospective review of all patients who sustained a distal humerus fracture treated operatively with ORIF at one academic institution between 2011 and 2015 was performed. Measured outcomes included complications, time to fracture union, painful hardware, removal of hardware, Mayo Elbow Performance Index (MEPI), and elbow range of motion. Differences in outcomes between patients who underwent surgery of their dominant upper extremity and those who underwent surgery of their non-dominant extremity were assessed. RESULTS: Sixty-nine patients met inclusion criteria. Forty (58.0%) underwent ORIF of a distal humerus fracture on their non-dominant arm and 29 (42.0%) on their dominant arm. Groups did not differ with respect to demographics, injury information, or surgical management. Mean overall follow-up was 14.1 ± 10.5 months, with all patients achieving at least 6 months follow-up. The non-dominant cohort experienced a higher proportion of postoperative complications (P = 0.048), painful hardware (P = 0.018), and removal of hardware (P = 0.002). At latest follow-up, the non-dominant cohort had lower MEPI scores (P = 0.037) but no difference in elbow arc of motion (P = 0.314). CONCLUSION: Patients who sustained a distal humerus fracture of their non-dominant arm treated with ORIF experienced more postoperative complications, reported a greater incidence of painful hardware, underwent removal of hardware more often, and had worse functional recovery in this study. Physicians should emphasize the importance of physical therapy and maintaining arm movement especially when the non-dominant arm is involved following distal humerus fracture repair.

Assessing the Potency of ß-Lactamase Inhibitors with Diverse Inactivation Mechanisms against the PenA1 Carbapenemase from Burkholderia multivorans.

Burkholderia cepacia complex (Bcc) poses a serious health threat to people with cystic fibrosis or compromised immune systems. Infections often arise from Bcc strains, which are highly resistant to many classes of antibiotics, including ß-lactams. ß-Lactam resistance in Bcc is conferred largely via PenA-like ß-lactamases. Avibactam was previously shown to be a potent inactivator of PenA1. Here, we examined the inactivation mechanism of PenA1, a class A serine carbapenemase from Burkholderia multivorans using ß-lactamase inhibitors (ß-lactam-, diazabicyclooctane-, and boronate-based) with diverse mechanisms of action. In whole cell based assays, avibactam, relebactam, enmetazobactam, and vaborbactam restored susceptibility to piperacillin against PenA1 expressed in Escherichia coli. The rank order of potency of inactivation in vitro based on kinact/KI or k2/K values (range: 3.4 × 102 to 2 × 106 M-1 s-1) against PenA1 was avibactam > enmetazobactam > tazobactam > relebactam > clavulanic acid > vaborbactam. The contribution of selected amino acids (S70, K73, S130, E166, N170, R220, K234, T237, and D276) in PenA1 toward inactivation was evaluated using site-directed mutagenesis. The S130A, R220A, and K234A variants of PenA1 were less susceptible to inactivation by avibactam. The R220A variant was purified and assessed via steady-state inhibition kinetics and found to possess increased Ki-app values and decreased kinact/KI or k2/K values against all tested inhibitors compared to PenA1. Avibactam was the most affected by the alanine replacement at 220 with a nearly 400-fold decreased acylation rate. The X-ray crystal structure of the R220A variant was solved and revealed loss of the hydrogen bonding network between residues 237 and 276 leaving a void in the active site that was occupied instead by water molecules. Michaelis-Menten complexes were generated to elucidate the molecular contributions of the poorer in vitro inhibition profile of vaborbactam against PenA1 (k2/K, 3.4 × 102 M-1 s-1) and was compared to KPC-2, a class A carbapenemase that is robustly inhibited by vaborbactam. The active site of PenA1 is larger than that of KPC-2, which impacted the ability of vaborbactam to form favorable interactions, and as a result the carboxylate of vaborbactam was drawn toward K234/T235 in PenA1 displacing the boronic acid from approaching the nucleophilic S70. Moreover, in PenA1, the tyrosine at position 105 compared to tryptophan in KPC-2, was more flexible rotating more than 90°, and as a result PenA1's Y105 competed for binding with the cyclic boronate vs the thiophene moiety of vaborbactam, further precluding inhibition of PenA1 by vaborbactam. Given the 400-fold decreased k2/K for the R220A variant compared to PenA1, acyl-enzyme complexes were generated via molecular modeling and compared to the PenA1-avibactam crystal structure. The water molecules occupying the active site of the R220A variant are unable to stabilize the T237 and D276 region of the active site altering the ability of avibactam to form favorable interactions compared to PenA1. The former likely impacts the ability of all inhibitors to effectively acylate this variant enzyme. Based on the summation of all evidence herein, the utility of these newer ß-lactamase inhibitors (i.e., relebactam, enmetazobactam, avibactam, and vaborbactam) in combination with a ß-lactam against B. multivorans producing PenA1 and the R220A variant is promising.

Can We Stratify Quality and Cost for Older Patients With Proximal and Midshaft Humerus Fractures?

INTRODUCTION: This study sought to investigate whether a validated trauma triage tool can stratify hospital quality measures and inpatient cost for middle-aged and geriatric trauma patients with isolated proximal and midshaft humerus fractures. MATERIALS AND METHODS: Patients aged 55 and older who sustained a proximal or midshaft humerus fracture and required inpatient treatment were included. Patient demographic, comorbidity, and injury severity information was used to calculate each patient's Score for Trauma Triage in the Geriatric and Middle-Aged (STTGMA). Based on scores, patients were stratified to create minimal, low, moderate, and high risk groups. Outcomes included length of stay, complications, operative management, ICU/SDU-level care, discharge disposition, unplanned readmission, and index admission costs. RESULTS: Seventy-four patients with 74 humerus fractures met final inclusion criteria. Fifty-eight (78.4%) patients presented with proximal humerus and 16 (21.6%) with midshaft humerus fractures. Mean length of stay was 5.5 ± 3.4 days with a significant difference among risk groups (P = 0.029). Lower risk patients were more likely to undergo surgical management (P = 0.015) while higher risk patients required more ICU/SDU-level care (P < 0.001). Twenty-six (70.3%) minimal risk patients were discharged home compared to zero high risk patients (P = 0.001). Higher risk patients experienced higher total inpatient costs across operative and nonoperative treatment groups. CONCLUSION: The STTGMA tool is able to reliably predict hospital quality measures and cost outcomes that may allow hospitals and providers to improve value-based care and clinical decision-making for patients presenting with proximal and midshaft humerus fractures. LEVEL OF EVIDENCE: Prognostic Level III.

Pull the Foley: Improved Quality for Middle-Aged and Geriatric Trauma Patients Without Indwelling Catheters.

INTRODUCTION: Urinary tract infection (UTI) complications are often attributed to the inappropriate use of urinary catheters. PURPOSE: We sought to examine the effectiveness of a hospital-wide policy aimed at reducing the use of indwelling Foley catheters. METHODS: We completed a retrospective review of prospectively collected data on 577 hip and femur fracture patients aged 55 years and older who were operatively treated at a Level 1 trauma center between October 2014 and March 2019. New standard-of-care guidelines restricting the use of indwelling Foley catheters were implemented starting January 2018, and we compared perioperative outcomes between cohorts. RESULTS: Over a 50% absolute reduction in indwelling Foley catheter use and a near 30% relative reduction in hospital-acquired UTI were achieved. Postpolicy cohort patients without indwelling Foley catheters experienced lower odds of hospital-acquired UTI, higher odds of home discharge, as well as decreased time to surgery, shorter length of stay, and lower total inpatient cost compared with those with indwelling Foley catheters. CONCLUSIONS: The policy of restricting indwelling Foley catheter placement was safe and effective. A decrease in indwelling Foley catheter use led to a decrease in the rate of hospital-acquired UTI and positively affected other perioperative outcomes.

Can We Accurately Predict Which Geriatric and Middle-Aged Hip Fracture Patients Will Experience a Delay to Surgery?

INTRODUCTION: This study sought to investigate whether a validated trauma triage risk assessment tool can predict time to surgery and delay to surgery. MATERIALS AND METHODS: Patients aged 55 and older who were admitted for operative repair or arthroplasty of a hip fracture over a 3-year period at a single academic institution were included. Risk quartiles were constructed using Score for Trauma Triage in the Geriatric and Middle-Aged (STTGMA) calculations. Negative binomial and multivariable logistic regression were used to evaluate time to surgery and delay to surgery, respectively. Pairwise comparisons were performed to evaluate 30-day mortality rates and demonstrate the effectiveness of the STTGMA tool in triaging mortality risk. RESULTS: Six hundred eleven patients met inclusion criteria with mean age 81.1 ± 10.5 years. Injuries occurred mainly secondary to low-energy mechanisms (97.9%). Median time to surgery (31.9 hours overall) was significantly associated with STTGMA stratification (P = .002). Moderate-risk patients had 33% longer (P = .019) and high-risk patients had 28% longer time to surgery (P = .041) compared to minimal risk patients. Delay to surgery (26.4% overall) was significantly associated with STTGMA stratification (P = .015). Low-risk patients had 2.14× higher odds (P = .009), moderate-risk patients had 2.70× higher odds (P = .001), and high-risk patients had 2.18× higher odds of delay to surgery (P = .009) compared to minimal risk patients. High-risk patients experienced higher 30-day mortality compared to minimal (P < .001), low (P = .046), and moderate-risk patients (P = .046). DISCUSSION: Patients in higher STTGMA quartiles encountered longer time to surgery, greater operative delays, and higher 30-day mortality. CONCLUSION: Score for Trauma Triage in the Geriatric and Middle-Aged can quickly identify hip fracture patients at risk for a delay to surgery and may allow treatment teams to optimize surgical timing by proactively targeting these patients. LEVEL OF EVIDENCE: Prognostic Level III.

Recognition and Management of Emergent Spinal Pathology Among First-Line Providers.

Spinal emergencies require prompt identification, management, and surgical referral (if needed) from first-line providers. Diagnostic delays from a failure to recognize emergency conditions can lead to adverse patient outcomes. The objective of this study was to understand the proficiency with which first-line providers can recognize and manage spinal conditions, particularly spinal emergencies. This was a cross-sectional analysis of 143 internal medicine, family medicine, emergency care, and neurology questionnaires collected at a single-site academic center. Participants were predominantly physicians (88.1%, n=126), with a smaller percentage of midlevel providers (11.9%, n=17). Only 35.0% (n=50) of respondents felt "very prepared" to handle spinal emergencies. Bivariate analyses revealed interdepartmental differences in clinical knowledge pertaining to the management of lumbar radiculopathy (P<.0001), epidural abscess (P=.0002), and cervical myelopathy (P<.0001). Following pairwise comparisons of interdepartmental differences, emergency medicine statistically outperformed internal medicine (P=.0007) and neurology (P<.0001) on initial management of lumbar radiculopathy, while also having markedly higher success in identifying and managing epidural abscess with respect to family medicine (P<.0001). The likelihood of appropriate initial treatment of cervical myelopathy was significantly higher for neurology than for emergency medicine (P<.0001). A minority of first-line providers reported being very prepared to handle spinal emergencies. Disparities exist between first-line provider specialties regarding clinical knowledge in managing and proficiently identifying emergent and nonemergent spinal conditions. Because appropriate handling of emergent spinal pathologies is essential to patient outcomes and optimal resource use, measures should be taken to further educate first-line providers regarding the spinal conditions they will be treating.

Fascial Hernia After Traumatic Tibial Shaft Fractures: A Cause of Chronic Leg Pain: A Report of 2 Cases.

CASE: This report reviews 2 cases of chronic lower extremity pain after traumatic tibial shaft fractures treated with intramedullary nail fixation. After examination and radiographic evaluation, clinical suspicion and pressure manometry were used to identify fascial herniation and indicate patients for fasciotomy, which ultimately relieved pain. CONCLUSIONS: Lower extremity fascial hernias typically present with nonspecific chronic pain. Ultrasonography and magnetic resonance imaging (MRI) can be used to confirm diagnosis. However, in patients with implanted hardware, MRI may be ineffective in detecting hernias because of artifact. Clinical suspicion and pressure manometry are effective ways of identifying patients with this etiology of chronic pain.

Marriage Status Predicts Hospital Outcomes Following Orthopedic Trauma.

INTRODUCTION: Rising costs of post-acute care facilities for both the patient and payers make discharge home after hospital stay, with or without home help, a favorable alternative for all parties. Our objectives were to assess the effect of marital status, a large source of social support for many, on disposition following hospital stay. METHODS: Patients were prospectively entered into an institutional review board-approved, trauma database at a large, academic medical center. Patients aged 55 years or older with any fracture injury between 2014 and 2017 were included. Retrospectively, their relationship status was recorded through review of patient records. A status of "married" was separated from those with a status self-reported as "single," "divorced," or "widowed." Multinomial logistic regression was used to assess whether discharge location differs by marital status while controlling for demographics and injury characteristics. RESULTS: Of 1931 patients, 8.3% were divorced, 29.9% were single, 20.0% were widowed, and 41.8% were married. There was a significant correlation between discharge disposition and marital status. Single patients had 1.71 times, and widowed patients had 1.80 times, the odds of being discharged to a nursing home, long-term care facility, or skilled nursing facility compared to married patients after controlling for age, gender, Score for Trauma Triage in the Geriatric and Middle-Aged score, and insurance type. Additionally, single and widowed patients experienced 1.36 and 1.30 times longer length of hospital stay than their married counterparts, respectively. DISCUSSION: Patients who are identified as "single" or "widowed" should have early social work intervention to establish clear discharge expectations. Early intervention in this way would allow time for contact with close, living relatives or friends who may be able to provide sufficient support so that patients can return home. Increasing home discharge rates for these patients would reduce lengths of hospital stay and reduce post-acute care costs for both patient and payers without materially altering unplanned readmission rates.

Nuclear Export Inhibition Enhances HLH-30/TFEB Activity, Autophagy, and Lifespan.

Transcriptional modulation of the process of autophagy involves the transcription factor HLH-30/TFEB. In order to systematically determine the regulatory network of HLH-30/TFEB, we performed a genome-wide RNAi screen in C. elegans and found that silencing the nuclear export protein XPO-1/XPO1 enhances autophagy by significantly enriching HLH-30 in the nucleus, which is accompanied by proteostatic benefits and improved longevity. Lifespan extension via xpo-1 silencing requires HLH-30 and autophagy, overlapping mechanistically with several established longevity models. Selective XPO1 inhibitors recapitulated the effect on autophagy and lifespan observed by silencing xpo-1 and protected ALS-afflicted flies from neurodegeneration. XPO1 inhibition in HeLa cells enhanced TFEB nuclear localization, autophagy, and lysosome biogenesis without affecting mTOR activity, revealing a conserved regulatory mechanism for HLH-30/TFEB. Altogether, our study demonstrates that altering the nuclear export of HLH-30/TFEB can regulate autophagy and establishes the rationale of targeting XPO1 to stimulate autophagy in order to prevent neurodegeneration.

Hospital competitive intensity and perioperative outcomes following lumbar spinal fusion.

BACKGROUND CONTEXT: Interhospital competition has been shown to influence the adoption of surgical techniques and approaches, clinical patient outcomes, and health care resource use for select surgical procedures. However, little is known regarding these dynamics as they relate to spine surgery. PURPOSE: This investigation sought to examine the relationship between interhospital competitive intensity and perioperative outcomes following lumbar spinal fusion. STUDY DESIGN/SETTING: This study used the Nationwide Inpatient Sample dataset, years 2003, 2006, and 2009. PATIENT SAMPLE: Patients were included based on the presence of the International Classification of Disease, Ninth Edition, Clinical Modification (ICD-9-CM) codes corresponding to lumbar spinal fusion, as well as on the presence of data on the Herfindahl-Hirschman Index (HHI). OUTCOME MEASURES: The outcome measures are perioperative complications, defined using an ICD-9-CM coding algorithm. MATERIALS AND METHODS: The HHI, a validated measure of competition within a market, was used to assess hospital market competitiveness. The HHI was calculated based on the hospital cachement area. Multiple regression was performed to adjust for confounding variables including patient age, gender, primary payer, severity of illness score, primary versus revision fusion, anterior versus posterior approach, national region, hospital bed size, location or teaching status, ownership, and year. Perioperative clinical outcomes were assessed based on ICD-9-CM codes with modifications. RESULTS: In total, 417,520 weighted patients (87,999 unweighted records) were analyzed. The mean cachement area HHI was 0.31 (range 0.099-0.724). The average patient age was 55.4 years (standard error=0.194), and the majority of patients were female (55.8%, n=232,727). The majority of procedures were primary spinal fusions (92.7%, n=386,998) and fusions with a posterior-only technique (81.5%, n=340,271). Most procedures occurred in the South (42.5%, n=177,509) or the Midwest (27.0%, n=112,758) regions. In the multiple regression analysis, increased hospital competitive intensity was associated with an increased total complication rate (odds ratio [OR] 1.52, p<.0001), device-related complications (OR 1.46, p=.0294), genitourinary complications (OR 2.15, p=.0091), infection (OR 3.48, p<.0001), neurologic complications (OR 1.69, p=.0422), total charges (+29%, p=.0034), and inpatient hospital length of stay (LOS) (+16%, p=.0012). The likelihood of complications at state-owned hospitals (OR 2.81, p=.0001) was more highly associated with HHI than at private, non-profit hospitals (OR 1.39, p=.0050). The occurrence of complications at urban teaching hospitals (OR 2.14, p<.0001) was generally more associated with HHI than at urban non-teaching hospitals (OR 1.19, p=.2457). CONCLUSIONS: Increased interhospital competitive intensity is associated with increased odds of complications, increased total charges, and prolonged LOS following lumbar spine fusion. These differences are generally highest among state-owned and urban teaching hospitals. Differences in outcome related to hospital competition may be due to suboptimal resource allocation. Identifying differences in perioperative outcomes associated with hospital market competition is important in the contemporary environment of health care reimbursement reform and hospital consolidation. Perioperative outcome disparities between highly competitive and minimally competitive areas should be monitored and further studied.

Medical Crowdfunding for Patients Undergoing Orthopedic Surgery.

Crowdfunding for medical expenses is growing in popularity. Through several websites, patients create public campaign profiles to which donors can contribute. Research on medical crowdfunding is limited, and there have been no studies of crowdfunding in orthopedics. Active medical crowdfunding campaigns for orthopedic trauma, total joint arthroplasty, and spine surgery were queried from a crowdfunding website. The characteristics and outcomes of crowdfunding campaigns were abstracted and analyzed. For this study, 444 campaigns were analyzed, raising a total of $1,443,528. Among the campaigns that received a donation, mean amount raised was $4414 (SE, $611). Multivariate analysis showed that campaigns with unspecified location (odds ratio, 0.26; P=.0008 vs West) and those for total joint arthroplasty (odds ratio, 0.35; P=.0003 vs trauma) had significantly lower odds of receipt of any donation. Description length was associated with higher odds of donation receipt (odds ratio, 1.13 per +100 characters; P<.0001). Among campaigns that received any donation, those with Southern location (-65.5%, P<.0001), international location (-68.5%, P=.0028), and unspecified location (-63.5%, P=.0039) raised lower amounts compared with campaigns in the West. Goal amount was associated with higher amount raised (+3.2% per +$1000, P<.0001). Resources obtained through crowdfunding may be disproportionately available to patients with specific diagnoses, those from specific regions, those who are able to craft a lengthy descriptive narrative, and those with access to robust digital social networks. Clinicians are likely to see a greater proportion of patients turning to crowdfunding as it grows in popularity. Patients may ask physicians for information about crowdfunding or request testimonials to support campaigns. Surgeons should consider their response to such requests individually. These findings shed light on the dynamics of medical crowdfunding and support robust personal and professional deliberation. [Orthopedics. 2018; 41(1):e58-e63.].

Laparoscopic management of enlarged serous cystadenoma in advanced pregnancy.

Operative laparoscopy is changing the methods of treatment of the acute abdomen in advanced pregnancy. Diagnostic capabilities in identification of benign disease are becoming more sensitive with the use of advanced imaging ultrasound scanning and magnetic resonance imaging. This has changed the deciding factors in the handling of advanced-size adnexal masses with minimally invasive techniques for the conservative management and treatment in advancing pregnancies. This case shows the successful removal of a 6198-g ovarian serous cystadenoma by use of minimally invasive techniques.
