Outcomes and role of peripheral revascularization in type A aortic dissection presenting with acute lower extremity ischemia.

OBJECTIVE: Limited data exists on management and outcomes of patients presenting with type A aortic dissection (TAAD) and acute lower extremity ischemia (ALI). The role of limb-related revascularization and optimal treatment strategy remains undefined. The objective of this study was to analyze dissection characteristics, treatment modalities, and outcomes of patients undergoing proximal aortic repair for TAAD with ALI. METHODS: Consecutive patients who underwent proximal aortic repair for TAAD were identified from a prospectively maintained database. Clinical data, imaging, operative details, and outcomes of patients with TAAD and ALI were retrospectively analyzed. Kaplan-Meier methodology was used to estimate overall and amputation-free survival. Log-rank tests were used to compare overall curves. Predictors of revascularization and in-hospital mortality were determined using multivariable logistic regression analysis. RESULTS: From 2010 to 2018, 463 patients with TAAD underwent proximal aortic repair. A total of 81 patients (17%) presented with ALI; 48% (39/81) with isolated ALI, and 52% (42/81) with ALI and renovisceral malperfusion. Thirty percent (24/81) required revascularization in addition to proximal aortic repair. Revascularization strategies involved endovascular (46%; 11/24), open (33%; 8/24), and hybrid (21%; 5/24) interventions. The major amputation rate was 4% (3/81), and in-hospital mortality was 21% (17/81). Amputation-free survival was significantly lower in patients requiring revascularization compared with those who did not (log-rank P = .023). Overall survival did not significantly differ between the two groups (log-rank P = .095). Overall survival was significantly lower in patients with concomitant ALI and renovisceral malperfusion compared with those with isolated ALI (log-rank P = .0017). Distal extent of dissection flap into zone 11 (odds ratio [OR], 5.65; 95% confidence interval [CI], 1.58-20.2; P = .008) and partial/complete thrombosis of any iliac artery (OR, 3.94; 95% CI, 1.23-12.6; P = .021) were associated with increased risk of requiring an additional revascularization procedure. True lumen collapse at level of renovisceral aorta (OR, 8.84; 95% CI, 1.74-44.9; P = .0086) was associated with increased risk of in-hospital mortality. CONCLUSIONS: ALI resolves after proximal aortic repair of TAAD in most cases. Distal extent of aortic dissection into zone 11 and iliac thrombosis are risk factors for additional peripheral revascularization. True lumen collapse at the renovisceral aorta and TAAD with concomitant ALI and renovisceral malperfusion portends a poor prognosis. A multi-disciplinary team approach to manage these patients who present with ascending aortic dissection and distal malperfusion may improve outcomes in this complex population.

Preoperative Vitamin D Concentration and Cardiac, Renal, and Infectious Morbidity after Noncardiac Surgery.

BACKGROUND: Low 25-hydroxyvitamin D is associated with cardiovascular, renal, and infectious risks. Postsurgical patients are susceptible to similar complications, but whether vitamin D deficiency contributes to postoperative complications remains unclear. We tested whether low preoperative vitamin D is associated with cardiovascular events within 30 days after noncardiac surgery. METHODS: We evaluated a subset of patients enrolled in the biobank substudy of the Vascular events In noncardiac Surgery patIents cOhort evaluatioN (VISION) study, who were at least 45 yr with at least an overnight hospitalization. Blood was collected preoperatively, and 25-hydroxyvitamin D was measured in stored samples. The primary outcome was the composite of cardiovascular events (death, myocardial injury, nonfatal cardiac arrest, stroke, congestive heart failure) within 30 postoperative days. Secondary outcomes were kidney injury and infectious complications. RESULTS: A total of 3,851 participants were eligible for analysis. Preoperative 25-hydroxyvitamin D concentration was 70 ± 30 nmol/l, and 62% of patients were vitamin D deficient. Overall, 26 (0.7%) patients died, 41 (1.1%) had congestive heart failure or nonfatal cardiac arrest, 540 (14%) had myocardial injury, and 15 (0.4%) had strokes. Preoperative vitamin D concentration was not associated with the primary outcome (average relative effect odds ratio [95% CI]: 0.93 [0.85, 1.01] per 10 nmol/l increase in preoperative vitamin D, P = 0.095). However, it was associated with postoperative infection (average relative effect odds ratio [95% CI]: 0.94 [0.90, 0.98] per 10 nmol/l increase in preoperative vitamin D, P adjusted value = 0.005) and kidney function (estimated mean change in postoperative estimated glomerular filtration rate [95% CI]: 0.29 [0.11, 0.48] ml min 1.73 m per 10 nmol/l increase in preoperative vitamin D, P adjusted value = 0.004). CONCLUSIONS: Preoperative vitamin D was not associated with a composite of postoperative 30-day cardiac outcomes. However, there was a significant association between vitamin D deficiency and a composite of infectious complications and decreased kidney function. While renal effects were not clinically meaningful, the effect of vitamin D supplementation on infectious complications requires further study.

Low Tidal Volumes Are Associated With Slightly Improved Oxygenation in Patients Having Cardiac Surgery: A Cohort Analysis.

BACKGROUND: Mechanical ventilation with low tidal volumes appears to provide benefit in patients having noncardiac surgery; however, whether it is beneficial in patients having cardiac surgery is unclear. METHODS: We retrospectively examined patients having elective cardiac surgery requiring cardiopulmonary bypass through a median sternotomy approach who received mechanical ventilation with a single lumen endotracheal tube from January 2010 to mid-August 2016. Time-weighted average tidal volume (milliliter per kilogram predicted body weight [PBW]) during the duration of surgery excluding cardiopulmonary bypass was analyzed. The association between tidal volumes and postoperative oxygenation (measured by arterial partial pressure of oxygen (PaO2)/fraction of inspired oxygen ratio [PaO2/FIO2]), impaired oxygenation (PaO2/FIO2 <300), and clinical outcomes were examined. RESULTS: Of 9359 cardiac surgical patients, larger tidal volumes were associated with slightly worse postoperative oxygenation. Postoperative PaO2/FIO2 decreased an estimated 1.05% per 1 mL/kg PBW increase in tidal volume (97.5% confidence interval [CI], -1.74 to -0.37; PBon = .0005). An increase in intraoperative tidal volumes was also associated with increased odds of impaired oxygenation (odds ratio [OR; 97.5% CI]: 1.08 [1.02-1.14] per 1 mL/kg PBW increase in tidal volume; PBon = .0029), slightly longer intubation time (5% per 1 mL/kg increase in tidal volume (hazard ratio [98.33% CI], 0.95 [0.93-0.98] per 1 mL/kg PBW; PBon < .0001), and increased mortality (OR [98.33% CI], 1.34 [1.06-1.70] per 1 mL/kg PBW increase in tidal volume; PHolm = .0144). An increase in intraoperative tidal volumes was also associated with acute postoperative respiratory failure (OR [98.33% CI], 1.16 [1.03-1.32] per 1 mL/kg PBW increase in tidal volume; PHolm = .0146), but not other pulmonary complications. CONCLUSIONS: Lower time-weighted average intraoperative tidal volumes were associated with a very modest improvement in postoperative oxygenation in patients having cardiac surgery.

Effectiveness of Shared Decision-Making for Elderly Depressed Minority Primary Care Patients.

OBJECTIVE: The authors assessed the impact of a shared decision-making (SDM) intervention among elderly depressed minority primary care patients not currently receiving treatment. METHODS: A total of 202 English and Spanish-speaking primary care participants aged 65 and older who scored positive on the Patient Health Questionnaire-9 (≥10) were randomized at the physician level to receive a brief SDM intervention or usual care (UC). Primary analyses focused on patient adherence to either psychotherapy or antidepressant medication, and reduction in depression severity (Hamilton Depression Rating Scale) over 12 weeks. RESULTS: Patients randomized to physicians in the SDM condition were significantly more likely than patients of physicians randomized to UC to receive a mental health evaluation or initiate some form of treatment (39% versus 21%), and to adhere to psychotherapy visits over 12 weeks. There were no differences between groups in adherence to antidepressant medication or in reduction of depressive symptoms. CONCLUSION: Among untreated elderly depressed minority patients from an inner-city municipal hospital, a brief SDM intervention was associated with greater initiation and adherence to psychotherapy. However, low treatment adherence rates across both groups and the intervention's lack of impact on clinical outcomes highlight the need to provide focused and accessible mental health services to patients choosing active treatments.

Two Interventions for Patients with Major Depression and Severe Chronic Obstructive Pulmonary Disease: Impact on Dyspnea-Related Disability.

OBJECTIVE: The Personalized Intervention for Depressed Patients with Chronic Obstructive Pulmonary Disease (PID-C) is an intervention aiming to help patients adhere to their rehabilitation and care. This study tested the hypothesis that the Problem-Solving Adherence (PSA) intervention, which integrates problem-solving into adherence enhancement procedures, reduces dyspnea-related disability more than PID-C. Exploratory analyses sought to identify patients with distinct dyspnea-related disability trajectories and to compare their clinical profiles. METHODS: In this randomized controlled trial in an acute inpatient rehabilitation and community, 101 participants diagnosed with chronic obstructive pulmonary disease (COPD) and major depression were included after screening 633 consecutive admissions for acute inpatient rehabilitation. Participants underwent 14 sessions of PID-C versus PSA over 26 weeks using the Pulmonary Functional Status and Dyspnea Questionnaire. RESULTS: The study hypothesis was not supported. Exploratory latent class growth modeling identified two distinct disability trajectories. Dyspnea-related disability improved in 39% of patients and remained unchanged in the rest. Patients whose dyspnea-related disability improved had more severe disability and less sense of control over their condition at baseline. CONCLUSION: Improvement or no worsening of disability was noted in both treatment groups. This is a favorable course for depressed patients with a severe, deteriorating medical illness. PID-C is compatible with the expertise of clinicians working in community-based rehabilitation programs, and after further testing in the community, it can be integrated in the care of depressed COPD patients.

Young, healthy South Asians have enhanced lipogenic sensitivity to dietary sugar.

OBJECTIVE: South Asians have higher rates of type 2 diabetes and cardiovascular disease compared to most other racial/ethnic groups. Increased hepatic de novo lipogenesis (DNL) in response to dietary sugar may accelerate the development of these chronic diseases in this population. STUDY DESIGN: Hepatic DNL in response to a calorically sweetened beverage was measured in an outpatient setting in 15 South Asians and 15 Caucasians with similar and normal body mass indexes, waist circumferences, glucose tolerance and lipid profiles. Blood was sampled before and hourly for 4 h after the ingestion of a single beverage made with glucose (1·5 g/kg) and fructose (1·5 g/kg). The main outcome, DNL, was measured as the increase in %palmitate (16:0) in very low-density lipoprotein (VLDL) triglyceride (TG) over 4 h. RESULTS: After the sugar dose, the increase in %16:0 in VLDL TG was significantly greater in South Asians vs Caucasians (P = 0·01). VLDL and total TG also increased to a significantly greater extent in South Asians (P = 0·04 and <0·001, respectively). Although the fasting and postsugar levels of insulin and glucose did not differ between groups, the DNL response significantly correlated with the insulin response to sugar in South Asians (r = 0·56, P = 0·03). CONCLUSIONS: Hepatic DNL in response to a sugar challenge was greater in healthy, young South Asians compared to Caucasians despite normal indices of insulin sensitivity, and it correlated with the insulin response. These findings suggest an early, insulin-related, gene-nutrient interaction contributing to the high prevalence of diabetes and coronary disease in this population.

Two Behavioral Interventions for Patients with Major Depression and Severe COPD.

OBJECTIVE: Personalized Intervention for Depressed Patients with COPD (PID-C), a treatment mobilizing patients to participate in their care, was found more effective than usual care. To further improve its efficacy, we developed a Problem Solving-Adherence (PSA) intervention integrating problem solving into adherence enhancement procedures. We tested the hypothesis that PSA is more effective than PID-C in reducing depressive symptoms. Exploratory analyses sought to identify patients with distinct depressive symptom trajectories and compare their clinical profiles. DESIGN: Randomized controlled trial. SETTING: Acute inpatient rehabilitation and community. PARTICIPANTS: A total of 101 diagnosed with chronic obstructive pulmonary disease (COPD) and major depression after screening 633 consecutive admissions for acute inpatient rehabilitation. INTERVENTION: Fourteen sessions of PID-C versus PSA over 26 weeks. MEASUREMENTS: 24-item Hamilton Depression Rating Scale. RESULTS: PSA was not more efficacious than PID-C in reducing depressive symptoms. Exploratory latent class growth modeling identified two distinct depressive symptoms trajectories. Unlike patients with unfavorable course (28%) who remained symptomatic, patients with favorable course (72%) had a decline of symptoms during the hospitalization followed by a milder decline after discharge. Patients with unfavorable course were younger and had greater scores in disability, anxiety, neuroticism, and dyspnea related limitation in activities and lower self-efficacy scores. CONCLUSIONS: Both interventions led to sustained improvement depressive symptoms. PID-C matches the skills of clinicians employed by community rehabilitation programs and can be integrated in the care of depressed COPD patients. Patients with severe disability, anxiety, neuroticism, and low self-efficacy are at risk for poor outcomes and in need of close follow-up and targeted interventions. .

Redefining "low risk": Outcomes of surgical aortic valve replacement in low-risk patients in the transcatheter aortic valve replacement era.

OBJECTIVES: Guidelines suggest aortic valve replacement (AVR) for low-risk asymptomatic patients. Indications for transcatheter AVR now include low-risk patients, making it imperative to understand state-of-the-art surgical AVR (SAVR) in this population. Therefore, we compared SAVR outcomes in low-risk patients with those expected from Society of Thoracic Surgeons (STS) models and assessed their intermediate-term survival. METHODS: From January 2005 to January 2017, 3493 isolated SAVRs were performed in 3474 patients with STS predicted risk of mortality <4%. Observed operative mortality and composite major morbidity or mortality were compared with STS-expected outcomes according to calendar year of surgery. Logistic regression analysis was used to identify risk factors for these outcomes. Patients were followed for time-related mortality. RESULTS: With 15 observed operative deaths (0.43%) compared with 55 expected (1.6%), the observed:expected ratio was 0.27 for mortality (95% confidence interval [CI], 0.14-0.42), stroke 0.65 (95% CI, 0.41-0.89), and reoperation 0.50 (95% CI, 0.42-0.60). Major morbidity or mortality steadily declined, with probabilities of 8.6%, 6.7%, and 5.2% in 2006, 2011, and 2016, respectively, while STS-expected risk remained at approximately 12%. Mitral valve regurgitation, ventricular hypertrophy, pulmonary, renal, and hepatic failure, coronary artery disease, and earlier surgery date were residual risk factors. Survival was 98%, 91%, and 82% at 1, 5, and 9 years, respectively, superior to that predicted for the US age-race-sex-matched population. CONCLUSIONS: STS risk models overestimate contemporary SAVR risk at a high-volume center, supporting efforts to create a more agile quality assessment program. SAVR in low-risk patients provides durable survival benefit, supporting early surgery and providing a benchmark for transcatheter AVR.

Post-cardiopulmonary bypass longitudinal strain provides higher prognostic ability than baseline strain or change in strain.

Context: Global longitudinal strain (GLS) measured by speckle-tracking echocardiography demonstrates excellent prognostic ability in predicting major adverse cardiac events after cardiac surgery. However, the optimal timing of intraoperative GLS measurement that provides the best prognostic value is unclear. Aim: Our goal was to evaluate whether GLS measured prior to cardiopulmonary bypass (pre-CPB GLS), following CPB (post-CPB GLS), or change in GLS provides the strongest association with postoperative complications. Setting and Design: Post hoc analysis of prospectively collected data from a clinical trial (NCT01187329). 72 patients with aortic stenosis undergoing elective AVR ± coronary artery bypass grafting between January 2011 and August 2013. Material and Methods: Myocardial deformation analysis from standardized transesophageal echocardiographic examinations were performed after anesthetic induction and chest closure. We evaluated the association between pre-CPB GLS, post-CPB GLS, and change in GLS (percent change from pre-CPB baseline) with postoperative atrial fibrillation and hospitalization >7 days. The association of post-CPB GLS with duration of mechanical ventilation, N-terminal pro-BNP (NT-proBNP) and troponin T were also assessed. Statistical Analysis: Multivariable logistic regression. Results: Risk-adjusted odds (OR[97.5%CI] of prolonged hospitalization increased an estimated 27% (1.27[1.01 to 1.59];Padj =0.035) per 1% decrease in absolute post-CPB GLS. Mean[98.3%CI] NT-proBNP increased 98.4[20 to 177]pg/mL; Padj =0.008), per 1% decrease in post-CPB GLS. Pre-CPB GLS or change in GLS were not associated with any outcomes. Conclusions: Post-CPB GLS provides the best prognostic value in predicting postoperative outcomes. Measuring post-CPB GLS may improve risk stratification and assist in future study design and patient outcome research.

Health-Related Quality of Life After Extensive Aortic Replacement.

To assess and compare patient-reported long-term health-related quality of life (HRQoL) after combined proximal aortic (arch ± ascending, root) and distal aortic (descending thoracic ± abdominal) replacement using open vs multimodal/endovascular (hybrid) approaches. From 2010 to 2016, 146 adults underwent single- or multi-stage aortic arch plus descending thoracic aorta replacement, 31 open and 115 hybrid. The 2 surgical approach groups had similar preoperative characteristics and extent of surgery. Cross-sectional follow-up revealed 49 deaths (7 open, 42 hybrid). Of the 97 survivors, 72 (74%) responded to the Patient-Reported Outcomes Measurement Information System (PROMIS) Global-10 survey (18 open, 54 hybrid) a median 6.2 years (15th, 85th percentiles: 3.1, 7.9) after their last aortic surgery. Predictors of HRQoL scores were identified by random forest regression. Overall physical HRQoL T-score was lower than that of population norms (46 vs 50, P < 0.0001); mental HRQoL T-score was similar (50 vs 50, P > 0.9). Neither T-score was significantly different according to surgical approach (P ≥ 0.3). Greater number of postoperative complications and history of chronic obstructive pulmonary disease were the most important predictors of lower physical HRQoL, and prior myocardial infarction was the most important predictor of lower mental HRQoL. Although extensive aortic replacement had a small long-term effect on patient-reported physical HRQoL, both physical and mental HRQoL can be preserved in survivors with both surgical approaches. Surgeons should recommend the approach they believe will yield the best long-term survival, but lifelong follow-up is crucial, and patients should understand that they may require multiple operations.

Admixture mapping of lung cancer in 1812 African-Americans.

Lung cancer continues to be the leading cause of cancer death in the USA and the best example of a cancer with undisputed evidence of environmental risk. However, a genetic contribution to lung cancer has also been demonstrated by studies of familial aggregation, family-based linkage, candidate gene studies and most recently genome-wide association studies (GWAS). The African-American population has been underrepresented in these genetic studies and has patterns of cigarette use and linkage disequilibrium that differ from patterns in other populations. Therefore, studies in African-Americans can provide complementary data to localize lung cancer susceptibility genes and explore smoking dependence-related genes. We used admixture mapping to further characterize genetic risk of lung cancer in a series of 837 African-American lung cancer cases and 975 African-American controls genotyped at 1344 ancestry informative single-nucleotide polymorphisms. Both case-only and case-control analyses were conducted using ADMIXMAP adjusted for age, sex, pack-years of smoking, family history of lung cancer, history of emphysema and study site. In case-only analyses, excess European ancestry was observed over a wide region on chromosome 1 with the largest excess seen at rs6587361 for non-small-cell lung cancer (NSCLC) (Z-score = -4.33; P = 1.5 × 10⁻5) and for women with NSCLC (Z-score = -4.82; P = 1.4 × 10⁻6). Excess African ancestry was also observed on chromosome 3q with a peak Z-score of 3.33 (P = 0.0009) at rs181696 among ever smokers with NSCLC. These results add to the findings from the GWAS in Caucasian populations and suggest novel regions of interest.

Renal injury after open versus laparoscopic non-cardiac surgery: a retrospective cohort analysis.

BACKGROUND: Laparoscopic surgical approaches enhance recovery, reduce postoperative pain, and shorten hospital length-of-stay. Nevertheless, increased intra-abdominal pressure is associated with decreased renal blood flow, renal hypoxia and acute kidney injury. When combined with Trendelenburg positioning, renal function may further deteriorate. We tested the primary hypothesis that the combination of laparoscopic surgical approach and Trendelenburg position is associated with larger reductions in estimated Glomerular Filtration Rate (eGFR) within the initial 48 postoperative hours compared to open surgery without Trendelenburg positioning. Secondarily, we tested, if laparoscopic procedures are associated with greater incidence of postoperative acute kidney injury. METHODS: Adults who had laparoscopic colorectal surgery in Trendelenburg position at the Cleveland Clinic Main Campus from 2009 to 2016 were propensity-matched to patients who had comparable open procedures. Patients with pre-existing renal impairment were excluded. RESULTS: Among 7,357 eligible patients, 1,846 laparoscopic cases with Trendelenburg were matched to 1,846 open cases. No association was found between laparoscopic approach and postoperative eGFR. A significant protective effect of the laparoscopic procedure on the odds of having AKI was found. Patients who had laparoscopic surgeries were an estimated 0.70 (95% CI 0.55, 0.90, pHolm-adj = 0.006) times as likely to have AKI as open surgical patients. CONCLUSION: Despite compelling potential mechanisms, laparoscopic approach with Trendelenburg position in adult colorectal surgeries did not worsen postoperative eGFR, and actually reduced postoperative acute kidney injury. Given the other advantages of laparoscopic surgery, the approach should not be avoided for concerns about renal injury.

From Court to Couch: Exercise and Quality of Life after Acute Type A Aortic Dissection.

BACKGROUND: Acute Type A aortic dissection can be physically and mentally stressful with little known about survivors' postrepair activity levels, exercise habits, and quality of life (QOL). This study was aimed to describe pre- and postdissection changes regarding exercise, understand physician recommendations, quantify use of cardiac rehabilitation, and assess QOL in dissection survivors. METHODS: A total of 295 acute Type A aortic dissection survivors were surveyed about exercise, cardiac rehabilitation, QOL, sexual activity, and posttraumatic stress disorder (PTSD) with 137 (46%) respondents. RESULTS: Respondents were less likely to participate in competitive athletics after than before dissection (1/131 [0.76%] vs. 26/131 [20%], p [McNemar test] < 0.0001) or lift heavy objects (11/111 [9.9%] vs. 41/111 [37%], p < 0.0001). Forty-eight of 132 respondents (36%) did not participate in cardiac rehabilitation. Compared with general population norms, respondents reported lower median QOL physical component scores (40 [26, 51; 15th, 85th percentile], p < 0.0001); these were lower in respondents who did not exercise (Hodges-Lehmann [HL; 95% confidence interval (CI)]: -6.8 [-11, -2.4], p = 0.002), limited sexual activity (-8.0 [-13, -4.3], p = 0.0002), or screened positive for PTSD (-10 [-14, -5.3], p = 0.0002). Median mental component scores were similar to general population norms (HL [95% CI]: 55 [34, 61], p = 0.24) but were lower among respondents who did not exercise (-4.2 [-7.8, -1.0], p = 0.01), limited sexual activity (-5.5 [-10, -1.8], p = 0.003), or screened positive for PTSD (-16 [-22, -10], p < 0.0001). CONCLUSION: Physicians should prescribe cardiac rehabilitation, encourage appropriate exercise, promote resumption of sexual activity, and identify and treat PTSD after surgery for acute Type A aortic dissection.

From Tear to Fear: Posttraumatic Stress Disorder in Patients With Acute Type A Aortic Dissection.

Background Acute type A aortic dissection presents with abrupt onset of pain that requires emergency surgery. However, minimal research exists on posttraumatic stress disorder (PTSD) in survivors. We aimed to quantify the prevalence and describe characteristics of PTSD in patients following dissection. Methods and Results A total of 295 adult survivors of surgical dissection with an email on file were administered a cross-sectional online survey about their dissection experience; 137 returned questionnaires, and 129 (94%) responded to the 4-item Primary Care PTSD portion of the survey that was part of a larger lifestyle survey designed to study survivors of aortic dissection and surgery. In addition to the PTSD screening, it inquired about current sexual activity, exercise habits, and employment within the preceding 30 days. At a median of 6.8 years (quartile 1=2.6, quartile 3=8.9 years) after dissection, 23% of patients (30/129) screened positive for PTSD, with 44% (57/129) stating that within the past month they felt constantly on guard or watchful or were easily startled. Of those who screened positive and matched to their electronic medical record (n=27), only 2 (7.4%) had been tested and clinically diagnosed with PTSD. Patients who screened positive for PTSD were more likely to report limited current sexual activity than those who did not (odds ratio, 5.3; 95% CI, 1.9-15 [P=0.0006]). Conclusions PTSD is an important mental health consideration in aortic dissection survivors. Physicians should screen these patients for PTSD at follow-up visits to identify those who test positive and refer them for further testing and treatment, such as trauma-focused psychotherapy or medication.

Association between higher BMI and postoperative pain and opioid consumption in pediatric inpatients - A retrospective cohort study.

BACKGROUND: Childhood and adolescent obesity increased in recent decades, and caregivers face an increasing number of obese pediatric surgical patients. Some clinical and pharmacogenetic data suggest that obese patients have altered pain sensitivity and analgesic requirements. OBJECTIVE: To test the primary hypothesis that increased BMI in pediatric patients is associated with increased pain during the initial 48 postoperative hours. Secondarily, we tested whether BMI is associated with increased opioid consumption during the same period. DESIGN: Retrospective single-center cohort study. SETTING: Pediatric surgical wards in a tertiary medical center. PATIENTS: A total of 808 opioid naïve patients aged 8 to 18 years having elective non-cardiac surgery with hospital stay of at least 48 h in the Cleveland Clinic between 2010 and 2015. INTERVENTIONS: None. MEASUREMENTS: Using U.S. Centers for Disease Control definitions for childhood weight classifications, we retrospectively evaluated the association between body mass index (BMI) percentile and time-weighted average pain scores and opioid consumption. We used multivariable linear regression to test for an association with postoperative pain scores, and multivariable gamma regression to test for an association with postoperative opioid consumption (in mg morphine equivalents Kg-1). RESULTS: BMI was not associated with postoperative pain after general, orthopedic, or neuro-spinal surgeries. Pain increased by 0.07 [98.75% CI: (0.01, 0.13), Padj < 0.05] points per 5 percentile increase in BMI after neuro-cranial surgery. Higher BMI was associated with a decrease in postoperative opioid consumption (mean change [95% CI] -2.12% [-3.12%, -1.10%] in morphine equivalents Kg-1 per 5 percentile increase in BMI, P < 0.001). CONCLUSION: We found no clinically important increase in pain scores or opioid consumption in association with higher BMI in patients 8 to 18 years of age recovering from elective non-cardiac surgery.

Chronic + binge alcohol exposure promotes inflammation and alters airway mechanics in the lung.

INTRODUCTION: Alcohol use disorders are major risk factors for the development of and susceptibility to acute respiratory distress syndrome. Although these risks of alcohol consumption on the lung are well described, mechanisms by which alcohol abuse promotes acute lung injury are poorly understood. These gaps in our understanding are due, at least in part, to limitations of animal models to recapitulate human alcohol consumption. Recently, a new model of chronic plus binge alcohol exposure was developed that is hypothesized to better model drinking patterns of individuals with alcohol use disorders. Specifically, this paradigm models chronic consumption coupled with periodic bouts of heavy drinking. The impacts of this alcohol-exposure regimen on the lung are uncharacterized. Therefore, the goal of this study was to examine lung injury and inflammation in a well-characterized experimental model of chronic + binge alcohol exposure. METHODS: 10-week-old male C57Bl6/J mice were administered ethanol-containing (or isocaloric control) liquid diet for 10 days, followed by a single ethanol gavage (5 g/kg). Lung inflammation and pulmonary function were assessed. RESULTS: Ten days of ethanol-containing liquid diet alone (chronic) did not detectably affect any variables measured. However, ethanol diet plus gavage (chronic + binge) caused neutrophils to accumulate in the lung tissue and in the bronchoalveolar lavage fluid 24 h post-binge. This inflammatory cell recruitment was associated with airway hyper-responsiveness to inhaled methacholine, as indicated by elevated resistance, Newtonian resistance, and respiratory resistance. CONCLUSIONS: Taken together, the novel findings reveal that ethanol alone, absent of any secondary inflammatory insult, is sufficient to produce inflammation in the lung. Although these changes were relatively mild, they were associated with functional changes in the central airways. This animal model may be useful in the future for identifying mechanisms by which alcohol abuse sensitizes at-risk individuals to lung injury.

Assessment of Patient Knowledge of Longitudinal Melanonychia: A Survey Study of Patients in Outpatient Clinics.

IMPORTANCE: Subungual melanoma (SM) is a rare subtype of cutaneous melanoma but carries a worse prognosis than similarly staged cutaneous melanomas. Assessing patient knowledge of melanonychia is integral to early diagnosis of SM. OBJECTIVES: The aim of this paper is to determine patient knowledge of longitudinal melanonychia (LM) and warning signs for SM, frequency of nail self-examinations, and satisfaction of patients with their physician's nail examinations. DESIGN SETTING AND PARTICIPANTS: We conducted a survey-based study of 363 random patients at Weill Cornell Medicine in New York, USA, performed at 3 different clinics: a general dermatology clinic (n = 167), a nail specialty clinic (n = 44), and a primary care clinic (n = 152). MAIN OUTCOMES AND MEASURES: Knowledge of the ABCDEF mnemonic for SM was compared to the ABCD mnemonic for cutaneous melanoma. Analyses were performed for patient behavior regarding suspicious nail changes as well as satisfaction with nail counseling and examination. RESULTS: Only 5% (18/363) of the patients in our study had heard of the ABCDEF mnemonic. In contrast, 9.9% (36/363) of the patients had heard of the ABCD mnemonic for cutaneous melanoma. In total, 37/363 (10.2%) patients reported having LM, 32.4% (12/37) of the patients noted changes in color or width of the band, and 10.8% (4/37) presented with pain or bleeding of the nail, with only 45.9% (17/37) seeking medical attention. Only 11.8% (43/363) of the patients stated that their physician asked them about nail changes, and 1.4% (5/363) of the patients stated that they were counseled about the ABCDEF mnemonic. In comparison, 13.8% (50/363) of the patients were advised on the ABCD mnemonic for the cutaneous melanoma mnemonic. While 70.2% (255/363) of the patients stated that they used sunscreen or wore sun-protective clothing, only 31.4% (114/363) assessed their nails for color changes, with 54.9% (128/233) of the patients categorizing themselves as "very unsatisfied" with the evaluation of their nails by their dermatologist. CONCLUSIONS AND RELEVANCE: Our data shows that there is a lack of patient knowledge of LM and warning signs for SM. Further testing is needed to determine whether educating patients about LM, warning signs for SM, and nail self-examinations would improve patient outcomes.

Adherence to Depression Treatment in Primary Care: A Randomized Clinical Trial.

Importance: Nonadherence to antidepressant medication is common and leads to poor outcomes. Early nonadherence is especially problematic. Objective: To test the effectiveness of a psychosocial intervention to improve early adherence among older patients whose primary care physician newly initiated an antidepressant for depression. Design, Setting, and Participants: The Treatment Initiation and Participation Program (TIP) was offered in a 2-site randomized clinical effectiveness study between January 2011 and December 2014 at primary care practices in New York, New York, and Ann Arbor, Michigan. Analyses began in February 2016. All participants were middle-aged and older adults (aged ≥55 years) who received newly initiated depression treatment by their primary care physician and recruited within 10 days of their prescription. Analyses were intention-to-treat. Interventions: Participants were randomly assigned to the intervention (TIP) or treatment as usual. Participants in the TIP group identified and addressed barriers to adherence, including stigma, misconceptions, and fears about treatment, before developing a personalized adherence strategy. The Treatment Initiation and Participation Program was delivered in three 30-minute contacts scheduled during a 6-week period just after the antidepressant was prescribed. Main Outcomes and Measures: The primary outcome was self-reported adherence on the Brief Medication Questionnaire, with adequate early adherence defined as taking 80% or more of the prescribed doses at 6 and 12 weeks. The secondary outcome was depression severity. Results: In total, 231 middle-aged and older adults (167 women [72.3%] and 64 men [27.7%]) without significant cognitive impairment were randomly assigned to the TIP intervention (n = 115) or treatment as usual (n = 116). Participants had a mean (SD) age of 67.3 (8.4) years. Participants in the TIP group were 5 times more likely to be adherent at 6 weeks (odds ratio, 5.54; 95% CI, 2.57 to 11.96; χ21 = 19.05; P < .001) and 3 times more likely to be adherent at both 6 and 12 weeks (odds ratio, 3.27; 95% CI, 1.73 to 6.17; χ21 = 13.34; P < .001). Participants in the TIP group showed a significant earlier reduction (24.9%) in depressive symptoms (95% CI, 13.9 to 35.9; t337 = 4.46; adjusted P < .001). In both groups, participants who were 80% adherent at weeks 6 and 12 had a 15% greater improvement in depressive symptoms from baseline over the course of treatment (95% CI, -0.2 to -30; t369 = 1.93; P = .051). Conclusions and Relevance: The Treatment Initiation and Participation Program is an effective intervention to improve early adherence to pharmacotherapy. Improved adherence can promote improvement in depression. Trial Registration: clinicaltrials.gov Identifier: NCT01301859.

Storm Impact and Depression Among Older Adults Living in Hurricane Sandy-Affected Areas.

OBJECTIVE: Research on the impact of natural disasters on the mental health of older adults finds both vulnerabilities and resilience. We report on the rates of clinically significant depression among older adults (aged ≥60 years) living in areas affected by Hurricane Sandy in 2012 and the factors associated with mental health need. METHODS: The Sandy Mobilization, Assessment, Referral and Treatment for Mental Health (SMART-MH) program integrates community outreach and needs assessments to identify older adults with mental health and aging service needs. Older adults with significant anxiety or depressive symptoms were offered short-term psychotherapy. Social service referrals were made directly to community agencies. All SMART-MH activities were offered in Spanish, Russian, Mandarin/Cantonese, and English. RESULTS: Across the full sample, 14% of participants screened positive for depression. Hurricane Sandy stressors predicted increased odds of depression, including storm injury, post-storm crime, and the total count of stressors. Outcomes varied significantly by age group, such that all Sandy-related variables remained significant for younger-old adults (aged 60-74 years), whereas only the loss of access to medical care was significant for older-old adults (aged ≥75 years). CONCLUSIONS: Storm-affected communities show higher rates of depressive symptoms than seen in the general population, with storm stressors affecting mental health needs differentially by age group.
