RESUMO

BACKGROUND: Adrenal venous sampling (AVS) is recommended before adrenalectomy for patients with primary aldosteronism (PA) over 35 years old. The literature examining contralateral suppression (CoS) on AVS in predicting surgical outcomes is conflicting. We examined the presence of CoS in patients who underwent adrenalectomy while adjusting for clinical and biochemical factors associated with a clinical cure of hypertension (ccHTN). METHODS: We performed a retrospective review of patients with successful AVS who underwent unilateral adrenalectomy for PA at a quaternary referral center. Patients were excluded if they had overt cortisol co-secretion, or inadequate follow-up. We first evaluated the aldosterone resolution score (ARS) in predicting ccHTN in our cohort. Next, the receiver-operator characteristic analysis (ROC) was used to determine the optimal contralateral suppression index (CSI) cutoff to define CoS. We performed univariable and multivariable analyses of factors associated with ccHTN. The primary outcome was ccHTN defined as blood pressure less than 140/90 mmHg, and off blood pressure medications. RESULTS: Of the 102 patients on bivariable analysis, age, sex, duration of HTN, number of medications, preoperative systolic blood pressure, and creatinine level were associated with ccHTN. ROC analysis of ARS had an AUC of 0.850 (p < 0.001). On multivariable analysis, only ARS remained associated with ccHTN (OR 3.40, 95% CI 1.20-9.61, p = 0.021). CSI was not significantly associated with ccHTN on ROC, bivariable, or multivariable analyses. CONCLUSION: The presence of CoS was not useful in predicting ccHTN following unilateral adrenalectomy for PA in our cohort. After adjusting for clinical and biochemical factors, ARS remains a useful predictor for ccHTN.

RESUMO

BACKGROUND: As an increasing number of general surgery residents apply for fellowship positions, it is important to identify factors associated with successful matriculation. For applicants to colon and rectal surgery, there are currently no objective data available to distinguish which applicant attributes lead to successful matriculation. OBJECTIVE: The purpose of this study was to identify objective factors that differentiate colon and rectal surgery fellowship applicants who successfully matriculate with those who apply but do not matriculate. DESIGN: This was a retrospective analysis of colon and rectal surgery applicant characteristics. SETTINGS: Deidentified applicant data provided by the Association of American Medical Colleges from 2015 to 2017 were included. MAIN OUTCOME MEASURES: Applicant demographics, medical school and residency factors, number of program applications, number of publications, and journal impact factors were analyzed to determine associations with successful matriculation. RESULTS: Most applicants (n = 371) and subsequent matriculants (n = 248) were white (61%, 62%), male (65%, 63%), US citizens (80%, 88%) who graduated from US allopathic medical schools (66%, 75%). Statistically significant associations included graduation from US allopathic medical schools (p < 0.0001), US citizenship (p < 0.0001), and number of program applications (p = 0.0004). Other factors analyzed included American Osteopathic Association membership (p = 0.57), university-based residency (p = 0.51), and residency association with a colon and rectal surgery training program (p = 0.89). Number of publications and journal impact factors were not statistically different between cohorts (p = 0.067, p = 0.150). LIMITATIONS: American Board of Surgery In-Training Examination scores, rank list, and subjective characteristics, such as strength of interview and letters of recommendation, were not available using our data source. CONCLUSIONS: Successful matriculation to a colon and rectal surgery fellowship program was found to be associated with US citizenship, graduation from a US allopathic medical school, and greater number of program applications. The remaining objective metrics analyzed were not associated with successful matriculation. Subjective and objective factors that were unable to be measured by this study are likely to play a determining role. See Video Abstract at http://links.lww.com/DCR/B415. EVALUACIN DE FACTORES VINCULADOS EN LA INMATRICULACIN EXITOSA PARA BECAS DE CIRUGA COLORRECTAL: ANTECEDENTES:A medida que un número cada vez mayor de residentes de Cirugía General solicitan una beca, es importante identificar los factores vinculados con una inmatriculación exitosa. Para los candidatos a una beca en Cirugía Colorrectal, hoy en día no existen datos objetivos disponibles para distinguir qué atributos del solicitante conducen a una inmatriculación exitosa.OBJETIVO:Identificar objetivamente los factores que diferencian un candidato a una beca en Cirugía Colorrectal que se inmatricula con éxito de aquel que aplica pero no llega a inmatricularse.DISEÑO:Análisis retrospectivo de las características de los solicitantes de beca para Cirugía Colorrecatl.AJUSTES:Datos de los solicitantes no identificados, proporcionados por la Asociación de Colegios Médicos Estadounidenses de 2015 a 2017.PRINCIPALES MEDIDAS DE RESULTADO:Se analizaron los factores demográficos del solicitante, las facultades de medicina y los factores de la residencia, el número de solicitudes de programas, el número y el factor de impacto de las publicaciones realizadas para determinar la asociación con una inmatriculación exitosa.RESULTADOS:La mayoría de los solicitantes (n = 371) que posteriormente fueron inmatriculados exitosamente (n = 248) eran blancos (61%, 62%, respectivamente), hombres (65%, 63%), ciudadanos estadounidenses (80%, 88%) que se graduaron de Facultades de medicina alopática en los EE. UU. (66%, 75%). Las asociaciones estadísticamente significativas incluyeron la graduación de las escuelas de medicina alopática de los EE. UU. (P <0,0001), la ciudadanía de los EE. UU. (P <0,0001) y el número de solicitudes de programas (p = 0,0004). Otros factores analizados incluyeron: membresía AOA (p = 0,57), la residencia universitaria (p = 0,51) y asociación de la residencia con un programa de formación en Cirugía Colorrectal (p = 0,89). El número de publicaciones y los factores de impacto de las revistas no fueron estadísticamente diferentes entre las cohortes (p = 0,067, p = 0,15, respectivamente).LIMITACIONES:El Score ABSITE, la posición en lista de clasificación y las características subjetivas como el de una buena entrevista y las cartas de recomendación no se encontraban disponibles en la fuente de datos.CONCLUSIONES:Se encontró que la inmatriculación exitosa a un programa de becas de Cirugía Colorreectal estaba asociada con la ciudadanía estadounidense, la graduación en una Facultad de medicina alopática en los EE. UU, y al mayor número de solicitudes de programas. El analisis de las medidas objetivas restantes no se asociaron con una inmatriculación exitosa. Es probable que los factores subjetivos y objetivos que no pudieron ser medidos por este estudio jueguen un papel determinante. Consulte Video Resumen en http://links.lww.com/DCR/B415.

RESUMO

BACKGROUND: Catecholamine excess in patients with pheochromocytomas or paragangliomas (PPGLs) can lead to hypertension, diabetes and hyperlipidemia. The aim was to investigate the prevalence of hyperlipidemia and the effect of surgical resection. METHODS: One hundred and thirty-two patients with PPGLs underwent an operation at the National Institutes of Health from 2009 to 2016, of which 54 patients met the inclusion criteria. Clinical demographics, BMI, genetic mutations, tumor size, perioperative catecholamine levels and perioperative lipid panels were retrospectively reviewed. Spearman correlation between catecholamines and lipid levels was evaluated. Paired Wilcoxon and paired t test were used to analyze differences in pre- and postoperative lipid levels. RESULTS: Preoperatively, 51 patients (94.4%) had elevated catecholamines, thirteen (24.1%) had elevated total cholesterol (TC) (>200 mg/dL), nine (16.6%) had elevated LDL (>130 mg/dL) and ten (18.5%) had elevated triglycerides (>150 mg/dL). Serum and urinary metanephrine levels were positively associated with TC (r = 0.2792, p = 0.0372 and r = 0.4146, p = 0.0031, respectively) and LDL levels (r = 0.2977, p = 0.0259 and r = 0.4434, p = 0.0014, respectively). Mean TC decreased from 176.4 to 166.3 mg/dL (p = 0.0064) and mean HDL decreased from 56.7 to 53.2 mg/dL (p = 0.0253) after PPGL resection (median 3.1 months (range 1.3-50.2) between lipid panels). Most patients with elevated TC (76.9%) had improvement with mean TC decreasing from 225 to 200.2 mg/dL (p = 0.0230). Of patients with elevated LDL, 66.7% had improvement with mean LDL decreasing from 149 to 131.1 mg/dL (p = 0.0313). CONCLUSIONS: The prevalence of hyperlipidemia in patients with PPGLs is 46%. Future prospective studies are needed to determine whether surgical resection improves TC and/or LDL levels.

RESUMO

Background: Use of e-cigarettes among college students has escalated, in part due to the perception that they are less harmful than traditional cigarettes and have other benefits such as circumventing smoking bans. College students also drink more heavily than other age groups, and e-cigarettes are associated with alcohol, especially among students who engage in problematic drinking.Objective: The present study sought to determine if an interaction between problematic alcohol use and increased perceptions of benefits and decreased perceptions of risks of e-cigarettes would predict whether participants had ever used an e-cigarette.Method: The present study included 1,133 undergraduate college students surveyed between November 2014 - November 2016. Participants were primarily Caucasian (82.3%) and female (78.1%). Participants completed questionnaires regarding demographics, smoking status/history, and expectancies.Results: Higher levels of problematic drinking and higher perceived benefits of e-cigarette use were both associated with having tried e-cigarettes. This relationship was significant even when controlling for several covariates such as cigarettes smoking status. However, there was not a significant interaction between problematic alcohol use and perceived benefits or risks of e-cigarettes. There was also no relationship between risk perceptions of e-cigarettes and e-cigarettes use.Conclusions: Both problematic alcohol use and perception of benefits of e-cigarettes were associated with having tried an e-cigarette. This finding is problematic as the use of e-cigarettes may influence further engagement in risky behaviors including problematic drinking or transitioning to regular cigarette use. Thus, it is important to develop interventions to help college students develop more accurate risk perceptions about e-cigarettes.

RESUMO

OBJECTIVE: We sought to understand the experiences of patients with lung cancer and to see if attitudes varied by demographic factors. METHODS: We administered a 63-question survey by phone or online among 174 patients with lung cancer. Factor analysis was used to identify two groups of questions with a conceptual relationship and high Cronbach's alphas, stigma and satisfaction with care. We used a multivariable analysis to identify predictors of self-blame and the factors of stigma and satisfaction with care. RESULTS: Patients were satisfied with the quality of their care and treatment choices but did not feel that there is enough public support for or research in lung cancer. Predictors of lower satisfaction with care were never being a smoker, lack of college education, not living in a rural location, refusing to report income, and not knowing/not being sure of stage. Self-blame was modest; in multivariable analysis, predictors of self-blame were believing that smoking was a cause of their lung cancer, younger age, male sex, living in a suburban location, and not knowing/not being sure of the stage of the cancer. Reported stigma was low and the only predictor for stigma was being married. Despite low scores on their personal experience of stigma, patients reported a high degree of stigmatization of lung cancer in general. Smoking was a significant predictor of personal stigma. CONCLUSION: Despite satisfaction with their treatment and care, lung cancer patients feel that society stigmatizes them as a general population. Patients who smoke are more likely to report that they have personally experienced stigma.

RESUMO

INTRODUCTION: Lung cancer screening represents an opportunity to deliver smoking cessation advice and assistance to current smokers. However, the current tobacco treatment practices of lung cancer screening sites are unknown. The purpose of this study was to describe organizational priority, current practice patterns, and barriers for delivery of evidence-based tobacco use treatment across lung cancer screening sites within the United States. METHODS: Guided by prior work examining readiness of health care providers to deliver tobacco use treatment, we administered a brief online survey to a purposive national sample of site coordinators from 93 lung cancer screening sites. RESULTS: Organizational priority for promoting smoking cessation among lung cancer screening enrollees was high. Most sites reported that, at the initial visit, patients are routinely asked about their current smoking status (98.9%) and current smokers are advised to quit (91.4%). Fewer (57%) sites provide cessation counseling or refer smokers to a quitline (60.2%) and even fewer (36.6%) routinely recommend cessation medications. During follow-up screening visits, respondents reported less attention to smoking cessation advice and treatment. Lack of patient motivation and resistance to cessation advice and treatment, lack of staff training, and lack of reimbursement were the most frequently cited barriers for delivering smoking cessation treatment. CONCLUSIONS: Although encouraging that lung cancer screening sites endorsed the importance of smoking cessation interventions, greater attention to identifying and addressing barriers for tobacco treatment delivery is needed in order to maximize the potential benefit of integrating smoking cessation into lung cancer screening protocols. IMPLICATIONS: This study is the first to describe practice patterns, organizational priority, and barriers for delivery of smoking cessation treatment in a national sample of lung cancer screening sites.

RESUMO

OBJECTIVES: To determine: 1) whether obese women perceive themselves to be obese or at risk for malignancy, 2) perceived impact of obesity on cancer risks, 3) compliance with cancer screening, and 4) rates of menstrual dysfunction. METHODS: Surveys were administered to female patients presenting for bariatric weight loss surgery. Demographics, gynecologic history, perception of cancer risk, and screening history were collected/analyzed. Women were categorized as obese (BMI: 30-39kg/m(2)), morbidly obese (40-49kg/m(2)), super obese (≥50kg/m(2)) and compared. RESULTS: Ninety-three women (mean age: 44.9 years, mean BMI: 48.7kg/m(2)) participated and 45.7% felt they were in 'good', 'very good', or 'excellent' health despite frequent medical comorbidities. As BMI increased, women were more likely to correctly identify themselves as obese (23% of obese vs. 77% of morbidly obese vs. 85% of super obese; p<0.001) but there were no significant differences in comorbidities. Two-thirds of women correctly identified obesity as a risk factor for uterine cancer, yet 48% of those retaining a uterus perceived that it was "not likely/not possible" to develop uterine cancer. Menstrual irregularities were common as was evaluation and interventions for the same; 32% had prior hysterectomy. Participation in cancer screening was robust. CONCLUSIONS: Women presenting for bariatric surgery have high rates of menstrual dysfunction. While they perceive that obesity increases uterine cancer risk, they often do not perceive themselves to be at risk. This disconnect may stem from the fact that many failed to identify themselves as obese perhaps because overweight/obesity has become the norm in U.S. society.

RESUMO

The current web-based survey investigated the association between team or individual sport participation (or both) and self-reported alcohol and tobacco use among high school athletes (N=1, 275) transitioning to college. Peak Blood Alcohol Concentration, weekly drinking, and alcohol-related problems were significantly lower among athletes in individual sports compared to other groups. Athletes competing in both team and individual sports reported greater lifetime tobacco use and combined alcohol/tobacco use compared to individual or team sports alone. Preventive strategies targeting HS athletes in general and those participating in team sports in particular may be useful in minimizing future alcohol use and related problems.

RESUMO

Adoptive cell transfer (ACT) with neoantigen-reactive T lymphocytes can mediate cancer regression. Here we isolated unique, personalized, neoantigen-reactive T cell receptors (TCRs) from tumor-infiltrating lymphocytes of patients with metastatic gastrointestinal cancers and incorporated the TCR α and ß chains into gamma retroviral vectors. We transduced autologous peripheral blood lymphocytes and adoptively transferred these cells into patients after lymphodepleting chemotherapy. In a phase 2 single-arm study, we treated seven patients with metastatic, mismatch repair-proficient colorectal cancers who had progressive disease following multiple previous therapies. The primary end point of the study was the objective response rate as measured using RECIST 1.1, and the secondary end points were safety and tolerability. There was no prespecified interim analysis defined in this study. Three patients had objective clinical responses by RECIST criteria including regressions of metastases to the liver, lungs and lymph nodes lasting 4 to 7 months. All patients received T cell populations containing ≥50% TCR-transduced cells, and all T cell populations were polyfunctional in that they secreted IFNγ, GM-CSF, IL-2 and granzyme B specifically in response to mutant peptides compared with wild-type counterparts. TCR-transduced cells were detected in the peripheral blood of five patients, including the three responders, at levels ≥10% of CD3+ cells 1 month post-ACT. In one patient who responded to therapy, ~20% of CD3+ peripheral blood lymphocytes expressed transduced TCRs more than 2 years after treatment. This study provides early results suggesting that ACT with T cells genetically modified to express personalized neoantigen-reactive TCRs can be tolerated and can mediate tumor regression in patients with metastatic colorectal cancers.

RESUMO

INTRODUCTION: Recent research has shown that body image stimuli increase negative affect and smoking urges among female smokers. Mindfulness (paying attention to present-moment experience with an attitude of nonjudgmental acceptance) may be a useful technique to minimize the influence of body dissatisfaction on negative affect, smoking urges, and smoking behavior. METHODS: This study investigated whether mindfulness influences how female college smokers respond to a body image challenge. The study used a 2 × 2 factorial design with body image challenge (trying on a bathing suit vs. looking at a purse) crossed with instructions (mindfulness vs. silence). Female smokers (n = 64; M (age) = 20.03 [± 1.77], 87.5% Caucasian) were randomly assigned to one of four conditions: Purse + Silence (n = 16), Body Image + Silence (n = 15), Purse + Mindfulness (n = 15), and Body Image + Mindfulness (n = 18).

RESUMO

Substance use is a perennial public health concern with associated health risks and economic impacts on society. In this article, we present a selective review of the epidemiological and clinical literatures on alcohol and substance use from a lifespan developmental perspective. We compare and contrast risk factors for the initiation of use and the development of a substance use disorder in adolescence, young adulthood, middle-age and later life. During adolescence, alcohol use experimentation is at its peak. Specific risk factors have been identified including trauma and parenting style that can increase the risk of substance use for teenagers. Emerging adults and college students are likely to experiment with other substances in addition to alcohol such as nicotine, marijuana, cocaine, and prescription medication such as Adderall. Middle-age and older adults with alcohol and substance use in their developmental histories may have an undiagnosed alcohol use disorder. Others will develop a late-onset substance use disorder in older age, possibly due to a dearth of social support, coping with bereavement, and medical complication. Based on Social Cognitive Theory, the roles of expectancies and self-efficacy are hypothesized to impact substance use and the risk of substance use disorder across the lifespan. Implications of the present review for future research on age-specific risk factors in alcohol use in relation to underlying developmental processes are considered.

RESUMO

Individuals with opioid use disorder (OUD) endorse high rates of combustible smoking (Zale et al., 2015) which is associated with poorer outcomes (e.g., opioid craving and lower detoxification completion rates) among individuals receiving medications for opioid use disorder (MOUD; Mannelli et al., 2013) and lower smoking cessation rates (Okoli et al., 2010). The complex pharmacological relationship between opioids and nicotine may help explain these findings (Kohut, 2017); however, little is known about psychosocial variables that influence MOUD processes among combustible smokers with OUD. The present study sought to expand upon prior work (Mannelli et al., 2013) by examining the impact of psychological factors and smoking-related variables on opioid withdrawal symptoms among smokers with OUD receiving Suboxone at an inpatient substance use treatment facility. Current smokers with OUD (N = 64) completed a battery of psychological measures examining depression, anxiety, and smoking constructs. The present study tested the influence of daily smoking rate, nicotine dependence, smoking urges, anxiety, and depression on opioid withdrawal symptoms through a hierarchical multiple regression. Findings revealed that smoking urges (p = .003) predicted severity of opioid withdrawal symptoms while controlling for race, daily smoking rate, and nicotine dependence. Depression (p = .000), however, explained variance in severity of opioid withdrawal symptoms above and beyond all smoking-related variables and anxiety. Results highlight the importance of considering psychological factors, specifically depression, which impact treatment processes among smokers with OUD to help inform the development of effective treatment interventions for both OUD and smoking cessation among individuals with OUD.

RESUMO

INTRODUCTION/OBJECTIVES: Despite the introduction of lung cancer screening using low dose computed tomography (LDCT), overall screening rates in the U.S. remain low, with certain populations including Black and rural communities experiencing additional disparities. The primary objective of this study was to understand the facilitators of lung cancer screening initiation and retention in Alabama reported by people at risk from mostly rural, mostly Black populations in Jefferson County-including the urban center of Birmingham-and 6 rural counties: Choctaw, Dallas, Greene, Hale, Marengo, and Sumter. METHODS: We conducted semi-structured telephone interviews with 58 people who underwent lung cancer screening between December 2019 and January 2022. Participant responses were recorded by the interviewer for analysis. Open-ended responses were coded to identify emergent themes. RESULTS: The most reported influences to initiate screening were information or suggestion from a Community Health Advisor (CHAs) or the supervising county coordinator, suggestion from a friend, or consideration of a personal history of smoking. Most participants reported multiple influences. Physicians were not very influential in decisions to initiate screening, but they were extremely influential in participants' intent to continue screening, both positively and negatively. Knowing the recommended timeline for their annual scans was also a predictor of intention to continue screening. Participants screened during the COVID-19 state of emergency expressed less certainty about dates of next scans and more ambivalence about intention to continue screening. CONCLUSIONS: This study shows the benefit of using multiple methods to support increased awareness of and interest in lung cancer screening, particularly when educational messaging through CHAs is used. Clear guideline-based messages from healthcare providers about recommended screening is important for increasing retention. COVID-19 related implementation challenges impacted screening recruitment and retention. Future research is warranted to further explore use of CHAs in lung cancer screening.

RESUMO

Background: Cancer-related financial hardship is linked to poor health outcomes and early mortality. Oncology financial advocacy (OFA) aims to prevent cancer-related financial hardship in oncology settings by assessing patients' needs and connecting them to available financial resources. Despite promising evidence, OFA remains underutilized. Objectives: Describe oncology financial advocates' perceptions about the challenges to and opportunities for implementing oncology financial advocacy (OFA) in community cancer centers. Methods: Nine virtual focus groups were conducted with 45 oncology financial advocates. Focus group transcripts were analyzed using template-based thematic analysis informed by the Consolidated Framework for Implementation Research (CFIR); two study team members coded each transcript and all six team members identified emergent themes. Results: Salient themes were identified across all five domains of the CFIR framework: (1) intervention characteristics: participants described challenges of adapting OFA to meet the needs of the medical system instead of needs of the patients; (2) outer setting: growing awareness of health and cancer disparities could bring more attention to and investment in OFA; (3) inner setting: programs are under-resourced to assist all at-risk patients, staffing, technology integration, and network/communication workflows are needed; (4) characteristics of individuals: advocates believe strongly in the effectiveness and would like to see their credibility enhanced with professional certification; (5) process: implementation strategies that target the engagement of leadership, key stakeholders, and patients to increase program reach are needed. Conclusions: OFA cannot reach all at-risk patients because of understaffing, poor communication between departments, and a lack of understanding OFA as an intervention among colleagues, key stakeholders, and patients. To reach full implementation, advocates need assistance in making the case for more resources, research on patient outcomes, professional certification, and the use of policy to incentivize financial advocacy as a standard of care in medicine.

RESUMO

Circulating T cells from peripheral blood (PBL) can provide a rich and noninvasive source for antitumor T cells. By single-cell transcriptomic profiling of 36 neoantigen-specific T cell clones from 6 metastatic cancer patients, we report the transcriptional and cell surface signatures of antitumor PBL-derived CD8+ T cells (NeoTCRPBL). Comparison of tumor-infiltrating lymphocyte (TIL)- and PBL-neoantigen-specific T cells revealed that NeoTCRPBL T cells are low in frequency and display less-dysfunctional memory phenotypes relative to their TIL counterparts. Analysis of 100 antitumor TCR clonotypes indicates that most NeoTCRPBL populations target the same neoantigens as TILs. However, NeoTCRPBL TCR repertoire is only partially shared with TIL. Prediction and testing of NeoTCRPBL signature-derived TCRs from PBL of 6 prospective patients demonstrate high enrichment of clonotypes targeting tumor mutations, a viral oncogene, and patient-derived tumor. Thus, the NeoTCRPBL signature provides an alternative source for identifying antitumor T cells from PBL of cancer patients, enabling immune monitoring and immunotherapies.

RESUMO

The study aim was to examine changes in food cue-elicited cravings and the macronutrient content of craved foods across menstrual cycle phases in a non-eating disordered sample. Thirty-five college females attended laboratory sessions in the late follicular and late luteal phases. In each session they completed a measure of state food craving before and after exposure to preferred, high fat/high sugar chocolate candy. Candy consumption following cue exposure was measured during an ad libitum "taste test." Additionally, participants rated their desire to eat foods differing systematically and significantly in macronutrient content. Ovulation was confirmed with luteinizing hormone detection kits. Results show that whereas the food cue increased cravings, this effect did not differ between cycle phases examined. The macronutrient content of foods desired also did not differ significantly between cycle phases, however, a non-significant trend suggested that high fat/high complex carbohydrate and low fat/high protein foods were more strongly desired in the late luteal phase. Amount of chocolate candy eaten did not differ between cycle phases. These results suggest that cravings for high fat/high sugar foods do not differ between menstrual cycle phases examined, whereas cravings for other foods may fluctuate across cycle phases in non-eating disordered women.

RESUMO

Cannabidiol (CBD), a nonpsychoactive cannabinoid, is used by many individuals to treat medical and mental health conditions, despite limited support for the efficacy of CBD for these conditions. Identification of CBD-related outcome expectancies (i.e., beliefs concerning the anticipated effects of CBD) could be useful in understanding the etiology and maintenance of CBD use and/or be useful in administration or clinical trial research. Although there are several measures of cannabis outcome expectancies, cannabis comprises several active compounds (e.g., tetrahydrocannabinol [THC], CBD). Thus, cannabis outcome expectancies may not reflect CBD-specific outcome expectancies. Yet, no known CBD-specific outcome expectancy measure exists. The present study used a three-phase, mixed-methods approach to develop and test the psychometric properties of the Cannabidiol Outcome Expectancy Questionnaire (CBD-OEQ). The CBD-OEQ assessed endorsement (i.e., how much an individual agrees/disagrees with an expected outcome) and desirability ratings (i.e., how desirable an expected outcome is). The initial item pool was administered to 600 adults who endorsed having heard of or using CBD products. Factor analyses supported a 60-item, six-factor structure. There was an initial support for internal consistency and convergent, discriminant, and incremental validity of the CBD-OEQ subscale scores in the present sample. Desirability ratings explained minimal additional variance in CBD variables for most subscales, but moderated the relationship between endorsement ratings and use behaviors for Global Negative Effects and No Effect subscales. The newly developed CBD-OEQ could be used as both a research and a clinical tool. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

RESUMO

Exogenous and endogenous female hormones influence nicotine use and cessation, potentially through mechanisms such as anxiety and negative affect. In the present study, college females using all types of hormonal contraceptives (HC) were compared to those not using HC to determine the potential influence on current smoking, negative affect, and current and past cessation attempts. Differences between progestin-only and combination HC were also examined. Of the 1,431 participants, 53.2% (n = 761) reported current HC use, and 12.3% (n = 176) of participants endorsed current smoking. Women currently using HC were significantly more likely to smoke (13.5%; n = 103) compared to women not using HC (10.9%; n = 73), p = .04. There was a significant main effect of HC use being associated with lower anxiety levels (p = .005), as well as a significant HC use by smoking status interaction, such that women who smoke using HC reported the lowest levels of anxiety among participants (p = .01). Participants using HC were more likely to be making a current attempt to quit smoking than those not using HC (p = .04) and were more likely to have made past quit attempts (p = .04). No significant differences were observed across women using progestin-only, combined estrogen and progestin, and women not using HC. These findings provide evidence that exogenous hormones may be an advantageous treatment target and that they warrant additional study.

RESUMO

PURPOSE: Immune checkpoint blockade (ICB) agents and adoptive cell transfer (ACT) of tumor-infiltrating lymphocytes (TIL) are prominent immunotherapies used for the treatment of advanced melanoma. Both therapies rely on activation of lymphocytes that target shared tumor antigens or neoantigens. Recent analysis of patients with metastatic melanoma who underwent treatment with TIL ACT at the NCI demonstrated decreased responses in patients previously treated with anti-PD-1 agents. We aimed to find a basis for the difference in response rates between anti-PD-1 naïve and experienced patients. PATIENTS AND METHODS: We examined the tumor mutational burden (TMB) of resected tumors and the repertoire of neoantigens targeted by autologous TIL in a cohort of 112 anti-PD-1 naïve and 69 anti-PD-1 experienced patients. RESULTS: Anti-PD-1 naïve patients were found to possess tumors with higher TMBs (352.0 vs. 213.5, P = 0.005) and received TIL reactive with more neoantigens (2 vs. 1, P = 0.003) compared with anti-PD-1 experienced patients. Among patients treated with TIL ACT, TMB and number of neoantigens identified were higher in ACT responders than ACT nonresponders in both anti-PD-1 naïve and experienced patients. Among patients with comparable TMBs and predicted neoantigen loads, treatment products administered to anti-PD-1 naïve patients were more likely to contain T cells reactive against neoantigens than treatment products for anti-PD-1 experienced patients (2.5 vs. 1, P = 0.02). CONCLUSIONS: These results indicate that decreases in TMB and targeted neoantigens partially account for the difference in response to ACT and that additional factors likely influence responses in these patients.
