Frailty is Not Associated with Worse Outcomes following Lower Extremity Angiograms for Limb Ischemia in Nonagenarians.

Background: Endovascular interventions are performed routinely with minimal risk in younger populations. The safety and efficacy of endovascular interventions in nonagenarians is under examined. We sought to examine the following (1) mortality and limb salvage rates in the nonagenarian population and (2) whether frailty was associated with outcomes following lower extremity (LE) interventions for both acute limb ischemia (ALI) and chronic limb threatening ischemia (CLTI).

Diet Quality and Risk of Older-onset Crohn's Disease and Ulcerative Colitis.

Background: We aimed to assess the relationship between diet quality and risk of older-onset Crohn's disease [CD] and ulcerative colitis [UC].

Methods: We conducted a prospective cohort study of 83 147 participants from the Swedish Mammography Cohort and the Cohort of Swedish Men. We used food frequency questionnaires to calculate adherence scores to multiple derived healthy diet patterns: Alternate Healthy Eating Index [AHEI], Healthy Eating Index-2015 [HEI-2015], Healthful Plant-Based Diet Index [HPDI], and modified Mediterranean Diet Score [mMED] at baseline in 1997 in both cohorts.

DNA methylation in people with anorexia nervosa: Epigenome-wide patterns in actively ill, long-term remitted, and healthy-eater women.

Objectives: Recent studies have reported altered methylation levels at disorder-relevant DNA sites in people who are ill with Anorexia Nervosa (AN) compared to findings in people with no eating disorder (ED) or in whom AN has remitted. The preceding implies state-related influences upon gene expression in people with AN. This study further examined this notion.

Disruption to well-being activities and depressive symptoms during the COVID-19 pandemic: The mediational role of social connectedness and rumination.

Background: Disruption to everyday routine during the COVID-19 pandemic has resulted in considerable implications for global mental health. The inter- and intra-personal mechanisms by which disrupted routine can contribute to elevated depressive symptoms has not been well-explored. The present study aimed to examine how feelings of social (dis)connectedness and rumination, as a maladaptive coping strategy, could explain the association between disrupted well-being activities and depressive symptoms.

Carotid Duplex Poorly Predicts Stroke Risk During Transcatheter Aortic Valve Replacement.

Introduction: Patients undergoing surgical aortic valve replacement, in isolation or with concomitant coronary artery bypass grafting, have historically been screened for carotid artery disease prior to surgery. Over the past decade, transcatheter aortic valve replacement (TAVR) has incrementally become the predominant technique for the treatment of severe aortic stenosis. The relationship between internal carotid artery stenosis (ICAS) and risk of periprocedural stroke in the TAVR population is uncertain.

Trends in Surgical Case Volume During Pacific Partnership Missions Onboard USNS Mercy.

Introduction: Since 2006, the U.S. Navy has conducted six Pacific Partnership (PP) missions throughout Southeast Asia on board the U.

Alcohol consumption and risk of inflammatory bowel disease among three prospective US cohorts.

Background And Aims: There are limited data on alcohol dose and types and risk of Crohn's Disease (CD) and Ulcerative Colitis (UC). We therefore sought to comprehensively examine the association between alcohol consumption and risk of CD and UC.

Methods: We conducted a prospective cohort study of 237,835 participants from the Nurses' Health Study, Nurses' Health Study II, and Health Professional Follow-Up Study.

Alcohol Consumption is Associated With An Increased Risk of Microscopic Colitis: Results From 2 Prospective US Cohort Studies.

Background: No dietary factors have yet been shown to conclusively impact the incidence of microscopic colitis (MC). Here, we sought to examine the relationship between alcohol intake and the risk of MC.

Methods: We conducted a prospective cohort study of 209,902 participants (age range, 28.

Obesity is Associated With Increased Risk of Crohn's disease, but not Ulcerative Colitis: A Pooled Analysis of Five Prospective Cohort Studies.

Background And Aims: It is unclear whether obesity is associated with the development of inflammatory bowel disease despite compelling data from basic science studies. We therefore examined the association between obesity and risk of Crohn's disease (CD) and ulcerative colitis (UC).

Methods: We conducted pooled analyses of 5 prospective cohorts with validated anthropometric measurements for body mass index (BMI) and waist-hip ratio and other lifestyle factors.

Left renal vein transposition for posterior Nutcracker syndrome.

Nutcracker syndrome (NCS) is a rare cause of pelvic venous congestion syndrome and is secondary to either compression of the left renal vein in its normal anatomic position by the superior mesenteric artery and aorta or less commonly when the left renal vein is in a retroaortic position, compressed between the aorta and the spine. We herein present a unique case of NCS in a female patient with a history of chronic pelvic pain and venous congestion. We also review the literature and discuss the diagnostic modalities, differential diagnosis, and various open surgical and endovascular options for NCS.

Birth weight is associated with adolescent brain development: A multimodal imaging study in monozygotic twins.

Previous research has shown that the prenatal environment, commonly indexed by birth weight (BW), is a predictor of morphological brain development. We previously showed in monozygotic (MZ) twins associations between BW and brain morphology that were independent of genetics. In the present study, we employed a longitudinal MZ twin design to investigate whether variations in prenatal environment (as indexed by discordance in BW) are associated with resting-state functional connectivity (rs-FC) and with structural connectivity.

Successful Return to Active Duty after First Rib Resection for Thoracic Outlet Syndrome.

Background: The optimal surgical approach and treatment algorithm for thoracic outlet syndrome (TOS) remain controversial. We sought to examine the outcomes of patients treated at a military medical treatment facility (MTF) for TOS.

Methods: A retrospective review was performed on all patients who had a first rib resection (FRR) for TOS over a 9-year period at a single MTF.

Isolated mycotic hypogastric artery aneurysm.

Isolated iliac artery aneurysms are rare and commonly associated with aortic aneurysms. Hypogastric artery aneurysms (HAAs) are exceptionally rare. The general approach to HAAs has been exclusion and bypass, although when this is complicated by mycotic disease, endovascular techniques can provide unique approaches to management.

A two-state comparative implementation of peer-support intervention to link veterans to health-related services after incarceration: a study protocol.

Background: Approximately 600,000 persons are released from prison annually in the United States. Relatively few receive sufficient re-entry services and are at risk for unemployment, homelessness, poverty, substance abuse relapse and recidivism. Persons leaving prison who have a mental illness and/or a substance use disorder are particularly challenged.

Differential Associations between Cortical Thickness and Striatal Dopamine in Treatment-Naïve Adults with ADHD vs. Healthy Controls.

Alterations in catecholamine signaling and cortical morphology have both been implicated in the pathophysiology of attention deficit/hyperactivity disorder (ADHD). However, possible links between the two remain unstudied. Here, we report exploratory analyses of cortical thickness and its relation to striatal dopamine transmission in treatment-naïve adults with ADHD and matched healthy controls.

Collaborative Approach to the Creation of an Arteriovenous Fistula on a US Navy Hospital Ship.

Early creation of arteriovenous fistulas (AVFs) decreases morbidity and mortality in patients with end-stage renal disease and is the standard of care in the United States. However, this procedure is frequently not accessible in low- and middle-income countries (LMICs). We present the first reported case of successful AVF creation as part of a humanitarian assistance mission.

Correlation between Subjective Nasal Patency and Intranasal Airflow Distribution.

Objectives (1) Analyze the relationship between intranasal airflow distribution and subjective nasal patency in healthy and nasal airway obstruction (NAO) cohorts using computational fluid dynamics (CFD). (2) Determine whether intranasal airflow distribution is an important objective measure of airflow sensation that should be considered in future NAO virtual surgery planning. Study Design Cross-sectional.

Giant Anterior Tibial Artery Pseudoaneurysm Successfully Treated on the USNS Mercy.

The need for an experienced vascular surgeon in the combat setting is not questioned; however, there is a paucity of literature exploring the utility of vascular surgery during an elective humanitarian mission. We herein present a case of a post-traumatic pseudoaneurysm of the anterior tibial artery treated in the context of a humanitarian mission during Pacific Partnership 2015 aboard the United States Naval Ship Mercy. This case report demonstrates the necessity and unique opportunities for vascular surgeons to participate in humanitarian surgery.

Birth weight discordance, DNA methylation, and cortical morphology of adolescent monozygotic twins.

Background: Several studies have shown that the in utero environment, which can be indexed by birth weight (BW), is associated with cortical morphology in adolescence and adulthood. Work in monozygotic (MZ) twins suggests that this association is driven by non-shared environmental factors. This correlation could be the result of in utero impacts on DNA methylation.

Correlation of Nasal Mucosal Temperature With Subjective Nasal Patency in Healthy Individuals.

Importance: Historically, otolaryngologists have focused on nasal resistance to airflow and minimum airspace cross-sectional area as objective measures of nasal obstruction using methods such as rhinomanometry and acoustic rhinometry. However, subjective sensation of nasal patency may be more associated with activation of cold receptors by inspired air than with respiratory effort.

Objective: To investigate whether subjective nasal patency correlates with nasal mucosal temperature in healthy individuals.
