Abstract OBJECTIVES This study analyzes the safety and outcomes of mitral valve repair for degenerative mitral valve regurgitation in patients 75 years of age or older. METHODS We retrospectively reviewed the clinical results of 343 patients aged ≥75 years who underwent mitral valve repair for degenerative mitral valve regurgitation as a primary indication between January 1998 and June 2017. RESULTS The median (interquartile range) age of the patients was 79.4 (76.9, 82.9) years, and 132 (38.5%) patients were women. Concomitant procedures were performed in 123 patients: tricuspid surgery in 68 (19.8%) and a maze procedure or pulmonary vein isolation in 55 (16.0%). Operative mortality was 1.2%. Operative complications included atrial fibrillation in 37.9%, prolonged ventilation in 7.0%, pacemaker implantation in 3.8, renal failure requiring dialysis in 1.5 and stroke in 3 (0.9%). The median follow-up was 7.4 years (interquartile range, 3.5–14.1 years). The cumulative incidence rates of mitral valve reoperation were 2.2%, 3.2% and 3.2% at 1, 5 and 10 years, respectively. Overall survival at 1, 5 and 10 years were 95%, 83% and 51%, respectively. Older age, smoking and over and underweight were associated with increased risk of mortality, while higher left ventricular ejection fraction and hypertension were associated with reduced risk. CONCLUSIONS Mitral valve repair in elderly patients can be accomplished with low operative mortality and complications. Mitral valve repair in the elderly remains the preferred treatment for degenerative mitral regurgitation.

Abstract Brain metastases occur commonly in patients with advanced solid malignancies. Yet, less is known about brain metastases than cancer-related entities of similar incidence. Advances in oncologic care have heightened the importance of intracranial management. Here, in this consensus review supported by the Society for Neuro-Oncology (SNO), we review the landscape of brain metastases with particular attention to management approaches and ongoing efforts with potential to shape future paradigms of care. Each coauthor carried an area of expertise within the field of brain metastases and initially composed, edited, or reviewed their specific subsection of interest. After each subsection was accordingly written, multiple drafts of the manuscript were circulated to the entire list of authors for group discussion and feedback. The hope is that the these consensus guidelines will accelerate progress in the understanding and management of patients with brain metastases, and highlight key areas in need of further exploration that will lead to dedicated trials and other research investigations designed to advance the field.

Haiti’s Central Plateau region suffers from significant malnutrition, economic hardship, and a crisis level of food insecurity. Already the poorest country in the Western Hemisphere in terms of gross domestic product (GDP) per capita, Haiti has pervasively high malnutrition rates, but the Central Plateau is among the most severely affected areas. One in five children of the Central Plateau suffers from malnutrition, and the region exhibits a devastating 30% rate of child stunting. Our US-based team affiliated with Klinik Sen Jozèf, a community-respected medical clinic in the Central Plateau city of Thomassique. We partnered with local Haitian leadership, a local agronomist, and Trees That Feed Foundation to introduce breadfruit (Artocarpus altilis) and an innovative development model to combat local malnutrition. Five years into the program, we have partnered with 152 farmers, and we have enhanced our malnutrition program with breadfruit derivatives. This report addresses the lessons we learned to assist others looking to introduce models or crops in a similar manner. Our experience is particularly significant in light of the COVID-19 pandemic, as supply chain disruptions have worsened food insecurity for more than 800 million people in low-income countries.

Objectives: To determine whether 2 different methods of post-operative head and neck free flap monitoring affect flap failure and complication rates. Methods: A retrospective chart review of 803 free flaps performed for head and neck reconstruction by the same microvascular surgeon between July 2013 and July 2020 at 2 separate hospitals within the same healthcare system. Four-hundred ten free flaps (51%) were performed at Hospital A, a medical center where flap checks were performed at frequent, scheduled intervals by in-house resident physicians and nurses; 393 free flaps (49%) were performed at Hospital B, a medical center where flap checks were performed regularly by nursing staff with resident physician evaluation as needed. Total free flap failure, partial free flap failure, and complications (consisting of wound infection, fistula, and reoperation within 1 month) were assessed. Results: There were no significant differences between Hospitals A and B when comparing rates of total free flap failure, partial free flap failure, complication, or re-operation ( P = .27, P = .66, P = .65, P = .29, respectively). There were no significant differences in urgent re-operation rates for flap compromise secondary to thrombosis and hematoma ( P = .54). Conclusions: In our series, free flap outcomes did not vary based on the degree of flap monitoring by resident physicians. This data supports the ability of a high-volume, well-trained, nursing-led flap monitoring program to detect flap compromise in an efficient fashion while limiting resident physician obligations in the age of resident duty hour restrictions.

Abstract Introduction Greater trochanteric pain syndrome may often mimic pain generated from other sources. However, it is most commonly caused by gluteus medius and gluteus minimus tendinopathy or tear. The purpose of this technical report was to: 1) describe the ultrasound-guided fascial plane block technique targeting the superior gluteal nerve in the plane between gluteus medius/gluteus minimus to treat moderate-to-severe, chronic, refractory greater trochanteric pain syndrome; 2) anatomically correlate the procedure with cadaveric dissections demonstrating the structures being imaged and the tissues along the needle trajectory; 3) demonstrate the feasibility of the technique with serial dissection of one cadaveric specimen following injection with color dye. Technique description The ultrasound-guided fascial plane block targeting the superior gluteal nerve to treat moderate-to-severe, chronic, refractory greater trochanteric pain syndrome has been outlined with supporting ultrasound scans and anatomical dissections. The cadaveric dissections are correlated to the ultrasound scans of a healthy volunteer and provide visualization of the tissues in the needle trajectory. The feasibility study in a cadaveric specimen showed adequate stain of the superior gluteal nerve without spread to the piriformis muscle belly, the sciatic nerve, or the inferior gluteal nerve. Conclusions This ultrasound-guided fascial plane block is a feasible option for blocking the superior gluteal nerve without inadvertent involvement of the sciatic and inferior gluteal nerves. Further randomized controlled clinical trials are necessary to assess the clinical efficacy of the gluteus medius/gluteus minimus fascial plane block to treat moderate-to-severe, chronic, refractory greater trochanteric pain syndrome.

Abstract The principles of achieving an aesthetically pleasing and harmonious facial appearance are influenced by our evolving understanding of the three-dimensional topography of the face coupled with novel approaches to midface volumization and contouring. In parallel with the evolving landscape of facial aesthetic surgery, an increasing number of publications have emerged focusing on the role of intraoral buccal fat pad removal (BFPR) for the purposes of aesthetic midface contouring. The authors sought to emphasize an underreported and potentially preventable and untoward complication involving iatrogenic parotid duct injury following BFPR. The purpose of this publication is 3-fold: (1) to review the relevant anatomy and literature on intraoral BFPR, (2) to present a case example of this complication, and (3) to discuss treatment options as part of a proposed management algorithm. The authors detail the surgical indications for performing BFPR and review the relevant anatomic considerations. Complication prevention strategies are outlined, and details regarding avoidance of parotid duct injury are reviewed. The diagnostic criteria and clinical presentation of parotid duct injuries following BFPR are comprehensively outlined. The authors present a clinically actionable algorithm for managing a suspected or diagnosed parotid duct injury following BFPR. A clinical case example is discussed to highlight this complication, the diagnostic criteria, and the systematic and algorithmic approach to management. Intraoral BFPR is an incredibly valuable and powerful procedure that can improve facial contour in patients with buccal lipodystrophy or buccal fat pad pseudoherniation. The authors propose a proper diagnostic approach and treatment algorithm to manage this untoward complication. Level of Evidence: 5

AbstractBackgroundTwitter has emerged as a powerful networking and educational tool within the health care community. The instantaneous and casual nature of Twitter allows for easy access to a near limitless pool of medical professionals and the opportunity to share intra‐ and interprofessional knowledge. Beyond individual development, Twitter has the potential to positively impact pharmacy residency programs in a multitude of ways.ObjectiveThis article serves as a practical guide for pharmacy residency programs to implement and maintain a successful Twitter account.RecommendationsAt the program level, a Twitter account creates an official voice and brand while simultaneously providing detail and perspective beyond what a residency website may offer. Additionally, it allows for dynamic ground‐level engagement with prospective residency candidates, current residents, and preceptors which is mutually beneficial to the program audience. In the age of virtual recruitment, successfully utilizing digital tools to meet candidates where they are is essential for attracting the right candidate for the program. Implementation of a successful social media strategy has potential barriers that include garnering buy‐in from departmental leadership, operationalizing a social media team, and maintaining engagement momentum.ConclusionPharmacy residency programs should consider starting an official Twitter account.

Background: Iron-overload cardiomyopathy initially manifests with diastolic dysfunction and can progress to dilated cardiomyopathy if untreated. Previous studies have shown that patients with primary and secondary hemochromatosis can have subclinical left ventricle dysfunction with abnormalities on strain imaging. This study aimed to evaluate the relationship between cardiac T2* values and myocardial-wall strain in patients with hereditary hemochromatosis (HH) at the time of diagnosis and after a course of venesection treatment. Materials and Methods: Baseline cardiac magnetic resonance (CMR) at 3 T was performed in 19 patients with newly diagnosed HH with elevated serum ferritin levels and repeated after a course of treatment with venesection. Quantitative T2* mapping and strain analysis were performed offline using dedicated relaxometry fitting and feature-tracking software. Results: The majority (84%) of patients had normal baseline myocardial T2* values (mean 19.3 ms, range 8.9 to 31.2 ms), which improved significantly after venesection (mean 24.1 ms, range 11 to 38.1 ms) (P=0.021). Mean global radial strain significantly improved from 25.0 (range: 15.6 to 32.9) to 28.3 (range: 19.8 to 35.8) (P=0.001) and mean global circumferential strain improved, decreasing from −15.7 (range: −11.1 to −19.2) to −17.1 (range: −13.0 to −20.1) (P=0.001). Conclusion: Patients with HH may have normal T2* values in the presence of subclinical left ventricle dysfunction, which can be detected by abnormal radial and circumferential strain. As strain imaging improves following venesection in HH, it may serve as a useful biomarker to guide treatment.

Background: Cranial dural arteriovenous fistulas with cortical venous drainage are rare lesions that can present with hemorrhage. A high rate of rebleeding in the early period following hemorrhage has been reported, but published long-term rates are much lower. No study has examined how risk of rebleeding changes over time. Our objective was to quantify the relative incidence of rebleeding in the early and later periods following hemorrhage. Methods: Patients with dural arteriovenous fistula and cortical venous drainage presenting with hemorrhage were identified from the multinational CONDOR (Consortium for Dural Fistula Outcomes Research) database. Natural history follow-up was defined as time from hemorrhage to first treatment, rebleed, or last follow-up. Rebleeding in the first 2 weeks and first year were compared using incidence rate ratio and difference. Results: Of 1077 patients, 250 met the inclusion criteria and had 95 cumulative person-years natural history follow-up. The overall annualized rebleed rate was 7.3% (95% CI, 3.2–14.5). The incidence rate of rebleeding in the first 2 weeks was 0.0011 per person-day; an early rebleed risk of 1.6% in the first 14 days (95% CI, 0.3–5.1). For the remainder of the first year, the incidence rate was 0.00015 per person-day; a rebleed rate of 5.3% (CI, 1.7–12.4) over 1 year. The incidence rate ratio was 7.3 (95% CI, 1.4–37.7; P , 0.026). Conclusions: The risk of rebleeding of a dural arteriovenous fistula with cortical venous drainage presenting with hemorrhage is increased in the first 2 weeks justifying early treatment. However, the magnitude of this increase may be considerably lower than previously thought. Treatment within 5 days was associated with a low rate of rebleeding and appears an appropriate timeframe.
