ABSTRACT

BACKGROUND: Guidelines recommend screening for primary aldosteronism in patients diagnosed with hypertension and obstructive sleep apnea. Recent studies have shown that adherence to these recommendations is extremely low. It has been suggested that cost is a barrier to implementation. No analysis has been done to rigorously evaluate the cost-effectiveness of widespread implementation of these guidelines. METHODS: We constructed a decision-analytic model to evaluate screening of the hypertensive obstructive sleep apnea population for primary aldosteronism as per guideline recommendations in comparison with current rates of screening. Probabilities, utility values, and costs were identified in the literature. Threshold and sensitivity analyses assessed robustness of the model. Costs were represented in 2020 US dollars and health outcomes in quality-adjusted life-years. The model assumed a societal perspective with a lifetime time horizon. RESULTS: Screening per guideline recommendations had an expected cost of $47,016 and 35.27 quality-adjusted life-years. Continuing at current rates of screening had an expected cost of $48,350 and 34.86 quality-adjusted life-years. Screening was dominant, as it was both less costly and more effective. These results were robust to sensitivity analysis of disease prevalence, test sensitivity, patient age, and expected outcome of medical or surgical treatment of primary aldosteronism. The screening strategy remained cost-effective even if screening were conservatively presumed to identify only 3% of new primary aldosteronism cases. CONCLUSIONS: For patients with hypertension and obstructive sleep apnea, rigorous screening for primary aldosteronism is cost-saving due to cardiovascular risk averted. Cost should not be a barrier to improving primary aldosteronism screening adherence.

ABSTRACT

BACKGROUND: Resistant hypertension is common in patients with primary aldosteronism and in those with obstructive sleep apnea. Primary aldosteronism treatment improves sleep apnea. Despite Endocrine Society guidelines' inclusion of sleep apnea and hypertension co-diagnosis as a primary aldosteronism screening indication, the state of screening implementation is unknown. METHODS: All hypertensive adult patients with obstructive sleep apnea (n = 4751) at one institution between 2012 and 2020 were compared with a control cohort without sleep apnea (n = 117,815). We compared the association of primary aldosteronism diagnoses, risk factors, and screening between both groups. Patients were considered to have screening if they had a primary aldosteronism diagnosis or serum aldosterone or plasma renin activity evaluation. RESULTS: Obstructive sleep apnea patients were predominantly men and had higher body mass index. On multivariable analysis, hypertensive sleep apnea patients had higher odds of drug-resistant hypertension (odds ratio [OR] 2.70; P < .001) and hypokalemia (OR 1.26; P < .001) independent of body mass index, sex, and number of antihypertensive medications. Overall, sleep apnea patients were more likely to be screened for primary aldosteronism (OR 1.45; P < .001); however, few patients underwent screening whether they had sleep apnea or not (pre-guideline publication 7.8% vs 4.6%; post-guidelines 3.6% vs 4.6%; P < .01). Screening among eligible sleep apnea patients remained low prior to and after guideline publication (4.4% vs 3.4%). CONCLUSIONS: Obstructive sleep apnea is associated with primary aldosteronism risk factors without formal diagnosis, suggesting screening underutilization and underdiagnosis. Strategies are needed to increase screening adherence, as patients may benefit from treatment of concomitant primary aldosteronism to reduce sleep apnea severity and its associated cardiopulmonary morbidity.

ABSTRACT

Social impairments are common across many psychiatric conditions. Standardized dyadic assessments intended to elicit social affiliation between unacquainted partners are used to elucidate mechanisms that disrupt relationship formation and inform possible treatment targets; however, the psychometric properties of such paradigms remain poorly understood. This study evaluated the psychometric properties of a controlled social affiliation paradigm intended to induce connectedness between a target participant and trained confederate. Individuals with an anxiety or depressive disorder diagnosis (clinical group; n = 132) and those without (control group; n = 35) interacted face-to-face with a trained confederate; partners took turns answering a series of increasingly intimate questions about themselves. Social connectedness, affect, and affiliative behavior measures were collected during the interaction. Participant symptom and social functioning measures were collected to examine validity. The paradigm elicited escalating social connectedness throughout the task for both participants and confederates. Parallel forms (i.e., different question sets) elicited similar affiliation outcomes. Self-reported (but not behavioral) affiliation differed across some demographic variables (e.g., participant gender, Hispanic ethnicity). Within-task affiliation measures were associated with one another and with global social connectedness and social anxiety symptom measures, but not with somatic anxiety measures. Clinical participants reported lower social affiliation and positive affect reactivity and higher negative affect reactivity than healthy participants. These findings provide initial psychometric support for a standardized and controlled dyadic affiliation paradigm that could be used to reliably probe social disconnection mechanisms across psychopathology.

ABSTRACT

OBJECTIVES: Individuals with major depressive disorder (MDD) have problems with engaging in approach behaviour to potentially rewarding encounters, which contributes to the maintenance of depressive symptoms. Approach-avoidance training (AAT) retrains implicit approach tendencies, and behavioural activation (BA) promotes explicit approach behaviour in MDD. As a novel MDD treatment strategy, this study aimed to implement a brief, computerized version of BA integrated with implicit AAT. DESIGN: Adults with a principal diagnosis of MDD (N = 25) were randomly assigned to complete one of two versions of AAT - approach-positive faces (n = 12) or balanced approach of positive and neutral faces (n = 13) - concurrently with self-guided BA twice weekly for 2 weeks. METHODS: Outcomes included treatment completion rates; bias scores for automatic approach towards positive social cues; and symptom scales for depression, positive affect, social relationship functioning, anhedonia, and anxiety. RESULTS: Feasibility and acceptability of computerized BA + AAT were supported by moderate pre-treatment credibility and expectancy ratings and 80% treatment completion. Participants across both conditions displayed significant and large sized reductions in depression from pre- to post-assessment (Cohen's d = -1.23) that maintained three months later, as well as decreased anxiety and anhedonia and increased positive affect and social relationship functioning (medium to large effects). CONCLUSION: Results support the feasibility and potential efficacy of brief, computerized BA + AAT. Research is needed to determine whether AAT is additive to BA, and what AAT parameters best enhance treatment outcomes. PRACTITIONER POINTS: Brief, computerized behavioral activation plus approach/avoidance training (BA + AAT) may be acceptable and beneficial for some patients with moderate-to-severe major depression. Computer-delivered BA + AAT can be implemented as a largely self-guided program for MDD and could be administered remotely and/or with minimal clinician interaction. As this was a small proof of concept study, it cannot be determined which treatment components - AAT, BA, or both - contributed to positive clinical outcomes. Because BA + AAT was implemented in a research clinic, it remains unknown what treatment engagement and response would look like in community settings.

ABSTRACT

BACKGROUND: Anxiety and depressive disorders are often characterized by perceived social disconnection, yet evidence-based treatments produce only modest improvements in this domain. The well-established link between positive affect (PA) and social connectedness suggests that directly targeting PA in treatment may be valuable. METHOD: A secondary analysis of a waitlist-controlled trial (N=29) was conducted to evaluate treatment response and process of change in social connectedness within a 10-session positive activity intervention protocol-Amplification of Positivity (AMP)-designed to increase PA in individuals seeking treatment for anxiety or depression (ClinicalTrials.gov Identifier: NCT02330627). Perceived social connectedness and PA/negative affect (NA) were assessed throughout treatment. Time-lagged multilevel mediation models examined the process of change in affect and connectedness throughout treatment. RESULTS: The AMP group displayed significantly larger improvements in social connectedness from pre- to post-treatment compared to waitlist; improvements were maintained through 6-month follow-up. Within the AMP group, increases in PA and decreases in NA both uniquely predicted subsequent increases in connectedness throughout treatment. However, experiencing heightened NA throughout treatment attenuated the effect of changes in PA on connectedness. Improvements in connectedness predicted subsequent increases in PA, but not changes in NA. CONCLUSIONS: These preliminary findings suggest that positive activity interventions may be valuable for enhancing social connectedness in individuals with clinically impairing anxiety or depression, possibly through both increasing positive emotions and decreasing negative emotions.

ABSTRACT

BACKGROUND: Social disconnection is a common and pernicious feature of anxiety and depressive disorders, yet is insufficiently addressed by our best available treatments. To better understand why people with anxiety and depression feel socially disconnected, we tested a positive and negative valence systems framework informed by research on how normative social connections develop and flourish. METHOD: Individuals seeking treatment for anxiety or depression (N = 150) completed measures of perceived social connectedness, positive and negative valence temperament, social goals, affect, symptoms, and life satisfaction. RESULTS: Feeling less socially connected was associated with diminished life satisfaction, beyond clinical symptom severity. Regression analyses revealed that both diminished positive valence and heightened negative valence temperament, and their corresponding motivational and affective outputs, were significantly and uniquely (with no significant interaction between them) associated with lower perceived connectedness. LIMITATIONS: Data was cross-sectional and based on self-report-limiting conclusions about causality and social disconnection processes at different units of analysis. CONCLUSIONS: Understanding social disconnection through the lens of a positive and negative valence systems framework may inform transdiagnostic models and treatment approaches.

ABSTRACT

BACKGROUND: There is substantial evidence that resecting adrenal metastases can be safely accomplished and extend overall survival in select patients. However, patient access to this operation has not been studied at the population level. The purpose of this study was to determine differences in utilization rates of adrenal metastasectomy (ADMX) across patient populations. METHODS: The Healthcare Utilization Project National Inpatient Sample was used to identify patients who had adrenal metastases (ADM) and who underwent ADMX from 2007 to 2011. Patients were identified by ICD-9-CM diagnosis and procedure codes. Predictor variables included sex, race, median household income, and primary insurance payer. Primary outcomes included receiving an ADMX and same hospitalization mortality. Secondary outcomes included length of stay, infection, cardiac, pulmonary, and renal complications. Univariable and multivariable logistic regression models were used to identify statistical associations. RESULTS: 32,331 ADM and 1070 ADMX patients identified in the database. Despite similar comorbidities, Black patients had 0.30 (95% CI 0.21-0.41) lower odds to receive an ADMX compared to White patients. Medicaid patients had 0.38 (0.28-0.52) less odds and Private Insurance patients 1.18 (1.00-1.39) more odds to receive an ADMX compared to Medicare patients. Women had a 1.39 (1.22-1.58) higher odds ratio of undergoing ADMX compared to men. Of the ADMX cohort, there was no difference in same hospitalization mortality or surgical complications. CONCLUSIONS: Black and Medicaid patients underwent fewer adrenal metastasectomies despite similar comorbidities and postoperative outcomes. This suggests a potential disparity in access to this treatment that disproportionately affects Black and low-income patients, and prompts further study, outreach attempts, as well as, research into improving access.

ABSTRACT

BACKGROUND: Retroperitoneal laparoscopic adrenalectomy is gaining traction as a minimally invasive technique. One of the purported relative contraindications is BMI given the smaller working space. We hypothesize that other anthropometric measurements may be better predictors of operative time. METHODS: An IRB-approved, single-institution, retrospective study of 83 patients who underwent laparoscopic retroperitoneal adrenalectomy evaluated the association of anthropometric measurements taken from cross-sectional imaging and the primary outcome of operative time. Descriptive statistics were performed with Wilcoxon rank-sum test for continuous variables (median; IQR) and Chi-square (n; %) for categorical variables. A linear random effects model was used to model operative time. RESULTS: The majority of the patients were white (40; 48.2%) women (46; 55.4%) with a median age of 54 with interquartile range (IQR) of 43-63 and a median BMI of 27.8 (IQR 21.2-38.6). On univariable analysis, factors that led to longer operative time included right-sided operation (p = 0.04), male gender (p < 0.01), clinical diagnosis (p < 0.01), waist area (p < 0.01), waist/hip ratio (p < 0.01), periadrenal volume (p < 0.01), posterior adiposity index (PAI) (p < 0.01) and BMI (p < 0.01). Only side, order of operation, and periadrenal fat volume (p < 0.01, p = 0.02 and p < 0.01, respectively) remained independent predictors of increased operative time on multivariable analysis. CONCLUSION: This study demonstrates that anthropometric measurements, specifically periadrenal fat volume, and side of operation, are better predictors for increased operative time in laparoscopic retroperitoneal adrenalectomies than BMI. This information can help facilitate appropriate patient selection for this operative approach.

ABSTRACT

Social anxiety disorder (SAD) often involves difficulty developing relationships. Facial expressions are important in relationship formation, but data are limited regarding facial display production among persons with SAD during social interaction. The current study compared facial displays of individuals diagnosed with SAD (n=41) to control participants (n=24) as they interacted with a confederate; confederates and observers then rated their desire for future interaction with participants. Automated software used the Facial Action Coding System (FACS; Ekman & Friesen, 1978) to classify displays. During portions of the interaction that involved listening to partners, the SAD group smiled less frequently and less intensely than controls, and lower smiling was associated with others' lower desire for future interaction with participants. Diminished positive facial affect in response to interaction partners may disrupt relationship formation in SAD and may serve as an effective treatment target.

ABSTRACT

BACKGROUND: Inadequate weight loss following LAGB (laparoscopic adjusted gastric banding) requiring band removal and conversion to another bariatric procedure is common. There is a paucity of objective data to guide procedure selection. Single anastomosis modifications (SIPS, SADI, SADS) of the duodenal switch biliopancreatic division (DS-BPD) are being investigated. Laparoscopic sleeve gastrectomy (LSG) has become the most prevalent primary bariatric procedure and has been used for revision following LAGB. PURPOSE: The purpose is to investigate single-stage LAGB removal to LSG SADS (single anastomosis duodenal switch). A matched cohort analysis compared each revision to a similar patient having a primary procedure. This was performed to understand the impact of prior banding on outcomes with each procedure. MATERIALS AND METHODS: This is a retrospective study to investigate the outcomes of revision of LAGB for inadequate weight loss to LSG or SADS. To determine whether prior banding impairs results, a matched cohort was done comparing each revision to a patient that had a primary procedure. RESULTS: As expected, patients who had SADS had greater weight loss than LSG. There was no difference in peri-operative and early complications. Both procedures resulted in weight loss. Importantly, with matched cohort, prior LAGB decreased weight loss outcomes in LSG, but not SADS. CONCLUSION: Conversion of LAGB to LSG or SADS results in weight loss. The presence of LAGB decreases weight loss in LSG, but not in SADS. This can have important implications for long-term outcomes.

ABSTRACT

Hürthle cell predominant thyroid nodules often confound the diagnostic utility of fine needle aspiration biopsy (FNAB) with cytology often interpreted as a Hürthle cell lesion with an indeterminate risk of malignancy, Bethesda category (BC) III or IV. Molecular diagnostics for Hürthle cell predominant nodules has also been disappointing in further defining the risk of malignancy. We present a case of a slowly enlarging nodule within a goiter initially reported as benign on FNAB, BC II but on subsequent FNAB suspicious for a Hürthle cell neoplasm, BC IV. The patient had initially requested a diagnostic lobectomy for a definitive diagnosis despite a higher risk of malignancy based on the size of the nodule > 4 cm alone. To better tailor this patient's treatment plan, a newer expanded gene mutation panel, ThyroSeq® v3 that includes copy number alterations (CNAs) and was recently found to have greater positive predictive value (PPV) for identifying Hürthle cell carcinoma (HCC), was performed on the FNAB material. Molecular profiling with ThyroSeq® v3 was able to predict a greater risk of carcinoma, making a more convincing argument in favor of total thyroidectomy. Surgical pathology confirmed a Hürthle cell carcinoma with 5 foci of angioinvasion and foci of capsular invasion.

ABSTRACT

Individuals with social anxiety disorder (SAD) have difficulty forming social relationships. The prevailing clinical perspective is that negative emotions such as anxiety inhibit one's capacity to develop satisfying social connections. However, empirical findings from social psychology and affective neuroscience suggest that positive emotional experiences are fundamental to establishing new social bonds. To reconcile these perspectives, we collected repeated measurements of anxiety, positive emotions (pleasantness), and connectedness over the course of a controlled relationship formation encounter in 56 participants diagnosed with SAD (64% female; Mage=23.3, SD=4.7). Participants experienced both increases in positive emotions and decreases in anxiety throughout the interaction. Change in positive emotions was the most robust predictor of subsequent increases in connectedness, as well as a greater desire to engage one's partner in future social activities, above and beyond reductions in anxiety (medium to large sized effects). Those findings suggest that anxiety-based models alone may not fully explain difficulties in relationship formation in SAD, and underscore the potential value of considering positive emotional experiences in conceptual and treatment models of SAD.

ABSTRACT

Glutamatergic signaling abnormalities in cortico-striatal circuits are hypothesized to lead to the repetitive thoughts and behaviors of obsessive-compulsive disorder (OCD). To test this hypothesis, studies have used proton magnetic resonance spectroscopy (1H MRS) to measure glutamatergic compounds in the striatum of individuals with OCD. However, no studies have used methods that could measure glutamate minimally contaminated by glutamine and γ-aminobutyric acid (GABA) in striatal subregions. Therefore, in this study, a proton MRS imaging (1H MRSI) technique with relatively high spatial resolution at 3.0 T was used to measure minimally contaminated glutamate levels in three striatal subregions (i.e., dorsal caudate, dorsal putamen, and ventral striatum) in 15 unmedicated adults with OCD and 16 matched healthy control subjects. No significant group differences in glutamate levels were found in any of the three striatal subregions. In contrast, a study in unmedicated pediatric OCD patients that measured glutamatergic compounds in the dorsal caudate by MRS at 1.5 T found significant elevations. Further studies are warranted to assess whether these discrepant MRS findings are due to differences in subject age or MRS methodology, or potentially are associated with glutamatergic gene variants implicated in OCD.

ABSTRACT

OBJECTIVE: To examine mastery of life skills necessary for independent adulthood among perinatally HIV-infected (PHIV+) and perinatally HIV-exposed but uninfected (PHIV-) youth. METHODS: Participants were recruited from four medical centers in New York City as part of a longitudinal study. Data for this article came from interviews of 150 PHIV+ and 95 PHIV- youth (age 13-24 years) and their caregivers. Life skills mastery was assessed using the Ansell-Casey Life Skills Assessment (ACLSA). RESULTS: PHIV+ youth had lower daily living skill mastery than PHIV- youth according to both youth and caregivers, and lower self-care mastery according to caregiver report. No HIV-status group differences were found in social relationships scores, but PHIV- youth had higher scores than an ACLSA benchmark sample. CONCLUSIONS: PHIV+ youth may need supportive services in daily living and self-care needs to transition into adulthood. Normal-to-high functioning in social relationships may be important for learning to live independently.
