Do certain phrases in letters of recommendation predict success in fellowship performance?

BACKGROUND: Letters of recommendation (LORs) are a valued, yet imperfect tool. Program directors (PDs) score phrases such as give my highest recommendation and top 5 to 10% of students as positive. Although positive phrases are valued by PDs, there is no evidence that these phrases predict performance. We attempt to identify whether 12 specific phrases found in letters of recommendation predict future performance of fellows. METHODS: LORs were evaluated for 12 select phrases and statements. Alpha Omega Alpha (AOA) status, Step 2 Clinical Knowledge (CK) score, and whether the letter writer was personally known to our admission's committee were also categorized. Logistic regressions were performed to evaluate the relationship of the independent variables with fellow performance. RESULTS: Using multivariate logistic regression, one of the best residents (OR = 4.02, 95% CI (1.0, 15.9), p < 0.05), exceeds expectations (OR = 4.74, 95% CI (1.4, 16.3), p = 0.01), and give my highest recommendation (OR = 3.87, 95% CI (1.3, 11.7), p = 0.02) predicted positive performance. Highly recommend (OR = 0.31, 95% CI (0.1, 1.0), p < 0.05) and top 5 to 10% (OR = 0.05, 95% CI (0.0, 0.6), p = 0.02) predicted negative performance. The remaining phrases did not correlate to fellowship performance. CONCLUSION: The current LOR evaluation process may place undo importance on phrases that have limited bearing on a candidate's success in training. Training both letter readers and writers to avoid using coded language or avoid assigning improper importance to select phrases may help improve the candidate selection process.

Starting a Vascular Surgery Fellowship at a Rural Healthcare Center.

INTRODUCTION: In the United States, there is an anticipated critical shortage of vascular surgeons in the coming decades. The shortage is expected to be particularly pronounced in rural areas. Our institution serves a rural and underserved population in which the incidence and prevalence of cardiovascular disease continues to rise. Our institution maintains a general surgery residency and has all the required Accreditation Council for Graduate Medical Education (ACGME) rotations and educational infrastructure to support a vascular surgery fellowship. This study aims to analyze the vascular caseload at our institution to determine if we and other institutions with similar surgical volumes can support the creation of a 2-year vascular fellowship. METHODS: A single-site retrospective review of the number and type of vascular cases conducted at our institution between July 2016 and June 2021 was performed. The procedures were grouped into the following ACGME-defined categories: abdominal, cerebrovascular, complex, endovascular aneurysm repair, endovascular diagnostic or therapeutic, and peripheral. The total number and annual average for each category was obtained. Using the annual average, a 2-year estimate was calculated and compared to the ACGME minimum for each category. Our 2-year estimate was then compared to the national average for graduating vascular surgery fellows in order to generate a z-score for each category. RESULTS: In the specified period, 6100 total surgical procedures were performed by three vascular surgeons at our institution. Two thousand five hundred and seventy-eight of the 6100 procedures met at least one of the ACGME-defined category requirements. Our center greatly exceeded the requirements for each category except for abdominal. This is consistent with trends observed in most centers across the nation, which are seeing a decline in open repairs across all categories, especially in open abdominal repairs. Our center's vascular case volume shows no significant difference the national average in each ACGME category (P ≥ 0.05 for all). CONCLUSIONS: Despite our center's large vascular caseload and need for more vascular providers, there were not enough open abdominal cases performed to support the training of a vascular fellow. Given the continued decline in open aortic volume across the country, we anticipate that rural centers similar to our own will have difficulty establishing programs to train and recruit vascular surgeons. Flexibility in the abdominal category requirement or creation of open aortic fellowships may be necessary for smaller rural centers to train vascular surgeons and meet the future needs of the specialty.

Partial Claviculectomy to Relieve Tracheal Compression in an Adult Male with Osteomesopyknosis.

BACKGROUND: The clavicle is a long bone that forms the anterior border of the thoracic inlet. Anatomic abnormalities of the clavicle can lead to compression of the innominate artery and trachea due to mass effect. These anatomic abnormalities can be amenable to surgical resection, which can provide complete resolution of symptoms. METHODS: We present a case of tracheal compression by the innominate artery in an adult man, caused by a clavicular abnormality due to an underlying bone mineralization disorder, corrected by partial resection of the right clavicle. RESULTS: The patient underwent successful open surgical resection of his right clavicular head leading to resolution of his tracheal compression by the innominate artery. CONCLUSIONS: We believe that this is the first description of tracheal compression due to osteomesopyknosis. This case demonstrates that compression of the innominate artery due to a clavicular abnormality can be safely corrected via open surgical resection.

Surgical Resection of a Symptomatic Superior Vena Cava Lipoma: A Case Report and Literature Review.

BACKGROUND: Lipomas are the most common form of benign soft tissue neoplasms and most frequently occur in the subcutaneous tissue. Rarely does a lipoma primarily arise from the arteries or veins. The most common location for an intravascular lipoma is the inferior vena cava, and rarely lipomas originate in the superior vena cava (SVC). Large lipomas of the SVC may be associated with central venous occlusive symptoms. There are only 7 cases of SVC lipomas reported in the literature. Here, we present only the second case of a large symptomatic lipoma located in the SVC, right internal jugular vein, and innominate veins. METHODS: We present a case of a 5-cm lipoma located in the SVC, discovered incidentally and surgically resected via median sternotomy. RESULTS: The patient underwent a successful open surgical resection of a symptomatic lipoma located in his SVC. CONCLUSIONS: Lipomas of the SVC are exceptionally rare, with only 7 cases described in the literature. This case demonstrates that lipomas can be safely excised from the SVC leading to resolution of central venous occlusive symptoms. A comprehensive literature review reveals that surgical resection is generally without complication, leads to resolution of symptoms, and does not require long-term follow-up.

Lower-Extremity Arteriovenous Malformation Masquerading as Peripheral Artery Disease.

An arteriovenous malformation (AVM) refers to an anomalous, direct connection between an artery and a vein. Typically, these two vessels are interposed by high-resistance capillary beds, the absence of which results in a high-flow system from an artery into a vein. Venous vessel walls are not designed to handle such high-pressure blood flow, and their vessel wall structure becomes permanently altered and weakened. For this reason, AVMs are at an increased risk for hemorrhages and ruptures. AVMs present with a spectrum of symptoms, ranging from skin discoloration, ischemia in distal tissues, and heart failure from arteriovenous shunting. Here, we present a case of a patient who underwent amputation of his second left toe, initially thought to be a result of peripheral arterial disease (PAD) due to his extensive smoking history. Further imaging findings revealed a rare lower-extremity AVM as the source of his ischemia, not PAD. Ultimately, the treatment of the vascular anomaly and resolution of the patient's symptoms were achieved via transarterial embolization. This case emphasizes the importance of looking beyond PAD as the cause of distal lower-extremity ischemia and provides insights into an uncommon and often missed diagnosis of extracranial AVMs.

Median Arcuate Ligament Syndrome Masquerading as Functional Abdominal Pain Syndrome.

Median arcuate ligament syndrome refers to anatomical compression of the celiac artery and/or ganglion by fibrous attachments of the median arcuate ligament. It typically presents as a vague constellation of abdominal symptoms that are often initially attributed to various other gastrointestinal pathologies; thus, it can be very difficult to diagnose. We present a case of median arcuate ligament syndrome in a 68-year-old woman, whose diagnosis and treatment were delayed by many years as her symptoms were taught to be the result of functional abdominal pain syndrome, ultimately corrected by laparoscopic decompression of the celiac axis. This case demonstrates that surgical decompression of the celiac axis is an effective treatment for median arcuate ligament syndrome and the importance of continuing to reassess the clinical picture of patients labeled with functional abdominal pain syndrome.

A Faster DiSH: Hardware Implementation of a Discrete Cell Signaling Simulator.

Development of fast methods to conduct in silico experiments using computational models of cellular signaling is a promising approach toward advances in personalized medicine. However, software-based cellular network simulation has runtimes plagued by wasted CPU cycles and unnecessary processes. Hardware emulation affords substantial speedup, but prior attempts at hardware implementation of biological simulators have been limited in scope and have suffered from inaccuracies due to poor random number generation. In this work, we propose several simulation schemes utilizing novel random update index generation techniques for step-based and round-based stochastic simulations of cellular networks. Our results show improved runtimes while maintaining simulation accuracy compared to software implementations.
