RESUMO

PURPOSE: Cannabis use may introduce risks and/or benefits among people living with cancer, depending on product type, composition, and nature of its use. Patient knowledge of tetrahydrocannabinol (THC) or cannabidiol (CBD) concentration could provide information for providers about cannabis use during and after treatment that may aide in risk and benefit assessments. This study aimed to examine knowledge of THC or CBD concentration among patients living with cancer who consume cannabis, and factors associated with knowledge of cannabinoid concentrations. METHODS: People living with cancer who consumed cannabis since their diagnosis (n = 343) completed an anonymous, mixed-mode survey. Questions assessed usual mode of delivery (MOD), knowledge of THC/CBD concentration, and how source of acquisition, current cannabis use, and source of instruction are associated with knowledge of THC/CBD concentration. Chi-square and separate binary logistic regression analyses were examined and weighted to reflect the Roswell Park patient population. RESULTS: Less than 20% of people living with cancer had knowledge of THC and CBD concentration for the cannabis products they consumed across all MOD (smoking- combustible products, vaping- vaporized products (e-cigarettes), edibles-eating or drinking it, and oral- taking by mouth (pills)). Source of acquisition (smoking-AOR:4.6, p < 0.01, vaping-AOR:5.8, p < 0.00, edibles-AOR:2.6, p < 0.04), current cannabis use (edibles-AOR:5.4, p < 0.01, vaping-AOR: 11.2, p < 0.00, and oral-AOR:9.3, p < 0.00), and source of instruction (vaping only AOR:4.2, p < 0.05) were found to be variables associated with higher knowledge of THC concentration. CONCLUSION: Self-reported knowledge of THC and CBD concentration statistically differed according to MOD, source of acquisition, source of instruction, and current cannabis use.

RESUMO

BACKGROUND: The relationship between theoretically relevant psychosocial and behavioral variables and outcomes of metabolic and bariatric surgery remains unclear. Some studies have found that the presence of psychopathology, disordered eating, and impulsivity, either before surgery or during the early postoperative period, is associated with suboptimal postoperative weight loss. Other studies have not found these relationships. OBJECTIVE: Examine the relationship between psychopathology, disordered eating, impulsivity, and weight loss 24 months postoperatively. SETTING: Two large, urban university health systems. METHODS: Participant characteristics were collected using validated interviews, patient-reported outcome measures, and computerized assessment methods. Linear mixed effect models were used to test the association of the variables of interest on percent weight loss (%WL). RESULTS: Three hundred participants were enrolled at baseline; weight data at 24 months were available for 227 participants; between 181 and 53 individuals completed other outcome measures. The mean %WL was 23.3 ± 9.9% at 24 months. Patients who underwent Roux-en-Y gastric bypass lost more weight than those who underwent sleeve gastrectomy. The presence of subjective binge episodes at baseline was related to a greater %WL at 24 months; there were no other baseline predictors. The presence of eating disorder diagnoses and disordered eating symptoms after surgery were associated with smaller weight losses over 24 months. Current and lifetime psychopathology and impulsivity were unrelated to %WL at 24 months. CONCLUSION: Disordered eating after bariatric surgery was associated with a smaller %WL at postoperative year 2. Additional monitoring of these symptoms in the early postoperative period is recommended. Psychotherapeutic and/or dietary interventions may promote more optimal weight loss outcomes.

RESUMO

There is growing interest in cannabis use for cancer pain. This commentary aims to discuss the evidence surrounding cannabis use for cancer pain in the context of the long-racialized landscape of cannabis policies and the disparity in pain control among cancer patients holding minoritized racial identities. Much evidence surrounding both the benefits and harms of cannabis use in cancer patients, and all patients in general, is lacking. Although drawing on the research in cancer that is available, it is also important to illustrate the broader context about how cannabis' deep roots in medical, political, and social history impact patient use and health care policies. There are lessons we can learn from the racialized disparities in opioid risk mitigation strategies, so they are not replicated in the settings of cannabis for cancer symptom management. Additionally, the authors intentionally use the term "cannabis" here rather than "marijuana.: In the early 1900s, the lay press and government popularized the use of the word "marijuana" instead of the more common "cannabis" to tie the drug to anti-Mexican prejudice.

RESUMO

Rates of cigarette smoking in people with HIV (PWH) are two to three times higher than in people without HIV. Nicotine is metabolized by CYP2A6 and the nicotine metabolite ratio (NMR; 3-hydroxycotinine/cotinine) is a measure of nicotine clearance. Higher NMR has been observed in PWH and is associated with lower quit rates. Efavirenz, a mainstay antiretroviral therapy (ART) globally, partially upregulates its own metabolism through CYP2A6. We hypothesized that efavirenz also upregulates nicotine metabolism by CYP2A6, resulting in a higher NMR, and switching to non-efavirenz ART would decrease the NMR, potentially leading to improved quit rates. We compared the NMR during and after efavirenz use among PWH in a longitudinal, multisite cohort. Eligibility criteria included: (i) active cigarette smoking, (ii) ART switched from efavirenz-based to non-efavirenz-based regimen, (iii) plasma available at pre- and post-ART switch, and (iv) viral suppression during study period. Plasma cotinine and 3-hydroxycotinine were measured by liquid chromatography-tandem mass spectrometry. T-tests compared the NMR on and off efavirenz. Samples were collected between 2010 and 2019 in 72 PWH. The mean NMR difference after switching to a non-efavirenz-based regimen was -0.24 (SD: 0.37, P < 0.001); 44 PWH had at least a 0.1 decrease in NMR. Effect modification by race was present; Black PWH had a larger mean decrease. Our findings suggest that previously observed higher NMR among PWH may be due to direct pharmacologic effects of ART. Assessing the effect of ART on the NMR suggests that avoiding nicotine metabolism inducers could potentially increase quit rates.

RESUMO

CONTEXT: Prolonged management of critical illnesses in long-term acute care hospitals (LTACH) makes serious illness communication (SIC), a clinical imperative. SIC in LTACH is challenging as clinicians often lack training and patients are typically unable to participate-making caregivers central. OBJECTIVES: This qualitative descriptive study characterized caregiver engagement in SIC encounters, while considering influencing factors, following the implementation of Ariadne Labs' SIC training at a LTACH in the Northeastern United States. METHODS: Clinicians' documented SIC notes (2019-2020) were analyzed using directed content analysis. Codes were grouped into four categories generated from two factors that influence SIC-evidence of prognostic understanding (yes/no) and documented preferences (yes/no)-and caregiver engagement themes identified within each category. RESULTS: Across 125 patient cases, 251 SIC notes were analyzed. In the presence of prognostic understanding and documented preferences, caregivers acted as upholders of patients' wishes (29%). With prognostic understanding but undocumented preferences, caregivers were postponers of healthcare decision-making (34%). When lacking prognostic understanding but having documented preferences, caregivers tended to be searchers, intent on identifying continued treatment options (13%). With poor prognostic understanding and undocumented preferences, caregivers were strugglers, having difficulty with the clinicians or family unit over healthcare decision-making (21%). CONCLUSION: The findings suggest that two factors-prognostic understanding and documented preferences-are critical factors clinicians can leverage in tailoring SIC to meet caregivers' SIC needs in the LTACH setting. Such strategies shift attention away from SIC content alone toward factors that influence caregivers' ability to meaningfully engage in SIC to advance healthcare decision-making.

RESUMO

Cues associated with smoking can induce relapse, which is likely driven by cue-induced neurobiological and physiological mechanisms. For instance, greater relapse vulnerability is associated with increases in cue-induced insula activation and heightened cortisol concentrations. Determining if there is a link between such cue-induced responses is critical given the need for biomarkers that can be easily measured in clinical settings and used to drive targeted treatment. Further, comprehensively characterising biological reactions to cues promises to aid in the development of therapies that address this specific relapse risk factor. To determine whether brain and cortisol responses to smoking cues are linked, this study recruited 27 nicotine-dependent tobacco-smoking individuals and acquired whole-brain functional activation during a cue reactivity task; salivary cortisol was measured before and after scanning. The results showed that increases in blood-oxygen-level-dependent activation in the right anterior insula and right dorsolateral prefrontal cortex (DLPFC) when viewing smoking versus neutral cues were positively correlated with a post-scan rise in salivary cortisol concentrations. These brain regions have been previously implicated in substance use disorders for their role in salience, interoception and executive processes. These findings show that those who have a rise in cortisol following smoking cue exposure also have a related rise in cue-induced brain reactivity, in brain regions previously linked with heightened relapse vulnerability. This is clinically relevant as measuring cue-induced cortisol responses is a more accessible proxy for assessing the engagement of cue-induced neurobiological processes associated with the maintenance of nicotine dependence.

RESUMO

Despite increased rates of cannabis use among patients with cancer, there are gaps in our understanding of barriers to accessing cannabis. Social determinants of health (SDoH) are associated with access to healthcare, but few studies have evaluated how SDoH relate to cannabis access and use among cancer patients. We examined whether access to and modes of cannabis use differed across indicators of SDoH among patients receiving treatment from a large National Cancer Institute (NCI) designated cancer center. This anonymous cross-sectional survey was developed in collaboration with the NCI Cannabis Supplement consortium, which funded 12 supplements to NCI Center Core Grants across the United States. We evaluated the association of race, gender, income, and age with mode of cannabis use, source of obtaining cannabis, what influences their purchase, and medical cannabis certification status. Overall, 1,053 patients receiving treatment for cancer in Pennsylvania completed the survey and 352 (33.4%) reported using cannabis since their cancer diagnosis. Patients who identified as Black/African-American were less likely to have medical cannabis certifications (p=0.04). Males and Black/African-Americans were more likely to report smoking cannabis (vs other forms, ps<0.01) and to purchase cannabis from an unlicensed dealer/seller (p<0.01). Lower-income patients were more likely to be influenced by price and ease of access (ps<0.05). Although cannabis users were younger than non-users, age was not associated with any outcomes. The current data shed light on how critical drivers of health disparities (such as race, gender, and income) are associated with where patients with cancer obtain cannabis, what forms they use, and what may influence their purchase decisions.

RESUMO

BACKGROUND: Nearly 1 in 3 clinical trials end prematurely due to underenrollment. Strategies to enhance recruitment are often implemented without scientific rigor to evaluate efficacy. Evidence-based, cost-effective behavioral economic strategies designed to influence decision-making may be useful to promote clinical trial enrollment. OBJECTIVE: This study evaluated 2 behavioral economic strategies to improve enrollment and retention rates across 4 clinical trials: information provision (IP) and contingency management (CM; ie, lottery). IP targets descriptive and injunctive norms about participating in research and CM provides participants incentives to reinforce a target behavior. METHODS: A sample of 212 participants was enrolled across 4 clinical trials focused on tobacco use: 2 focused on HIV and 2 focused on neuroimaging. The CM condition included a lottery: for each study visit completed, participants received 5 "draws" from a bowl containing 500 "chips" valued at US $0, US $1, US $5, or US $100. In the IP condition, text messages that targeted injunctive norms about research (eg, "Many find it a rewarding way to advance science and be part of a community") were sent through the Way to Health platform before all study visits. Participants were randomized to 1 of 4 conditions: IP, CM, IP+CM, or standard recruitment (SR). We performed logistic regression, controlling for sex and study, with condition as a between-subject predictor. Outcomes were the percentage of participants who attended a final eligibility visit (primary), met intent-to-treat (ITT) criteria (secondary), and completed the study (secondary). Recruitment was evaluated by the percentage of participants who attended a final eligibility visit, enrollment by ITT status, and retention by the percentage of participants who completed the study. RESULTS: Rates of attending the eligibility visit and meeting ITT status were 58.9% (33/56) and 33.9% (19/56) for IP+CM; 45.5% (25/55) and 18.2% (10/55) for IP only; 41.5% (22/53) and 18.9% (10/53) for CM only; and 37.5% (18/48) and 12.5% (6/48) for SR, respectively. In the logistic regression, females were more likely to meet ITT status than males (odds ratio [OR] 2.7, 95% CI 1.2-5.7; P=.01). The IP+CM group was twice as likely to attend the final eligibility visit than the SR group (OR 2.4, 95% CI 1.1-5.2; P=.04). The IP+CM group was also significantly more likely to reach ITT status than the SR condition (OR 3.9, 95% CI 1.3-11.1; P=.01). Those who received any active intervention (IP, CM, or IP+CM) had a higher study completion rate (33/53, 63.5%) compared to those who received SR (5/12, 41.7%), but this difference was not significant (P=.26). CONCLUSIONS: Combining IP and CM strategies may motivate participants to participate in research and improve recruitment and retention rates. Evidence from this study provides preliminary support for the utility of behavioral economics strategies to improve enrollment and reduce attrition in clinical trials.

RESUMO

Racial and ethnic disparities in pain management pose major challenges to equitable cancer care delivery. These disparities are driven by complex interactions between patient-, provider-, and system-related factors that resist reductionistic solutions and require innovative, holistic approaches. On September 19, 2022, the Society for Integrative Oncology and the American Society of Clinical Oncology published a joint guideline to provide evidence-based recommendations on integrative medicine for cancer pain management. Integrative medicine, which combines conventional treatments with complementary modalities from cultures and traditions around the world, are uniquely equipped to resonate with diverse cancer populations and fill existing gaps in pain management. Although some complementary modalities, such as music therapy and yoga, lack sufficient evidence to make a specific recommendation, other modalities, such as acupuncture, massage, and hypnosis, demonstrated an intermediate level of evidence, resulting in moderate strength recommendations for their use in cancer pain management. However, several factors may hinder real-world implementation of the Society for Integrative Oncology and the American Society of Clinical Oncology guideline and must be addressed to ensure equitable pain management for all communities. These barriers include, but are not limited to, the lack of insurance coverage for many complementary therapies, the limited diversity and availability of complementary therapy providers, the negative social norms surrounding complementary therapies, the underrepresentation of racial and ethnic subgroups in the clinical research of complementary therapies, and the paucity of culturally attuned interventions tailored to diverse individuals. This commentary examines both the challenges and the opportunities for addressing racial and ethnic disparities in cancer pain management through integrative medicine.

RESUMO

BACKGROUND: Post-cessation weight gain (PCWG) is an obstacle to smoking cessation. This trial evaluated a behavioral intervention targeting alternative rewards to smoking and high calorie snacking to promote smoking cessation while mitigating PCWG. METHODS: Adult smokers (n = 288; 119 females, 169 males) received eight weeks of transdermal nicotine and were randomized to eight sessions of behavioral activation for smoking cessation and the mitigation of PCWG (BAS+) or standard smoking cessation counseling (SC). Primary outcomes were 7-day point prevalence abstinence and PCWG 26 weeks after the target quit date. Change in caloric intake from pre-treatment through the 26-week follow-up was a secondary outcome. Data were collected from September 2016 to February 2021, and analyses were completed in July 2022. RESULTS: BAS+ and SC did not differ in smoking abstinence rates at the 26-week follow-up (OR=0.80, 95%CI 0.50-1.27, p = 0.34; 18% versus 23%). There were no significant differences in PCWG between BAS+ and SC who were 7-day point prevalence abstinent (ß = -0.29, 95%CI -2.13 to 1.65, p = 0.77; 2.60 versus 2.20 pounds, respectively) or among those continuously abstinent (5.78 versus 5.34 pounds, respectively). There were no significant differences in caloric intake between BAS+ and SC from baseline to the 26-week follow-up (ß = 110.65, 95%CI -96.72 to 318.02, p = 0.30; -19.1 versus -116.9 kcals/day, respectively). CONCLUSIONS: The results do not support the efficacy of BAS+ for smoking cessation and the prevention of PCWG. These findings join a growing body of research highlighting the challenge of minimizing PCWG and promoting smoking abstinence.

RESUMO

INTRODUCTION: Identifying eating behaviors associated with suboptimal weight loss following bariatric surgery remains important. This study assessed the relationship between eating behaviors and weight loss following bariatric surgery in a racially diverse sample. METHODS: Participants were assessed before surgery and 6 and 12 months postoperatively, with the Structured Clinical Interview for DSM-5, the Eating Disorder Examination-Bariatric Surgery Version, and validated measures assessing a range of eating behaviors. Linear mixed effect models were used to test the impact of eating behaviors on percent weight loss (%WL) at 6 and 12 months. RESULTS: We enrolled 300 participants (mean age 40.1 years; BMI 45.9 kg/m2; 87% women; 62% Black and 30% White). The majority (82%) underwent sleeve gastrectomy (SG). Mean %WL was 23.0 ± 5.1% at 6 months and 26.2 ± 7.6% at 12 months. Subjective binge episodes prior to surgery predicted greater %WL over the first 12 postoperative months (p = 0.028). Postoperative disinhibition, hunger, night eating symptoms, objective binge episodes, global disordered eating attitudes and behaviors, and snacks per day were associated with smaller %WL over 12 months (all p's < 0.01). The presence of picking/nibbling and addictive-like eating behaviors was not associated with %WL at the end of the first postoperative year. CONCLUSION: Among a diverse participant sample, problematic eating behaviors following surgery were associated with smaller %WL over 12 months. Postoperative assessment and treatment of eating behaviors are needed to address these issues as they arise and to prevent attenuation of early weight loss in some patients.

RESUMO

Background: Medical use of cannabis is growing in popularity across the United States, but medical education and clinician comfort discussing cannabis use for medical purposes have not kept pace. Materials and Methods: A total of 344 clinicians in the state of Pennsylvania (response rate 14%) completed a brief online survey about their attitudes, training, and experiences regarding medical cannabis and certifying patients to use medical cannabis. Results: Only 51% of clinicians reported completing any formal training on medical cannabis. Compared with noncertifying clinicians (pharmacists, nurse practitioners, and physician assistants), physicians were significantly more comfortable with patient use of medical cannabis, saw fewer risks, more benefits, and felt better prepared to discuss its use with vulnerable populations. All clinicians noted significant limitations to their understanding of how medical cannabis can affect patients, and many indicated a desire for more research and training to fill in gaps in their knowledge. Conclusions: Insufficient medical curricula on the medical uses of cannabis are available to interprofessional clinicians across their disciplines, and clinicians report significant deficits in their knowledge base about its effects. Additionally, these data suggest an urgent need to expand training opportunities to the full spectrum of clinicians as all are involved in caring for patients who use medical cannabis.

RESUMO

People with HIV (PWH) smoke at higher rates compared with the general population and have lower cessation rates. The primary aim of this study was to examine the impact of the COVID-19 pandemic on smoking in PWH. A survey was administered to participants in two smoking cessation trials in the United States. Mean cigarettes per day was 13.9 (SD 8.6), and participants reported they had smoked on average for 30.93 years (SD 10.4). More than half (55.7%) of participants (N = 140) reported not changing their smoking during the pandemic, while 15% reported decreasing, and 25% reported increasing their smoking. In bivariate analyses, worrying about food due to lack of money (χ2 = 9.13, df 2, p = 0.01) and greater Covid-related worry (rs = 0.19, p = 0.02) were significantly associated with increased smoking. Qualitative research may be needed to more clearly elucidate factors related to smoking behaviors among PWH.

RESUMO

People with HIV (PWH) report substance use at higher rates than HIV-uninfected individuals. The potential negative impact of single and polysubstance use on HIV treatment among diverse samples of PWH is underexplored. PWH were recruited from the Center for Positive Living at the Montefiore Medical Center (Bronx, NY, USA) from May 2017-April 2018 and completed a cross-sectional survey with measures of substance use, antiretroviral therapy (ART) use, and ART adherence. The overall sample included 237 PWH (54.1% Black, 42.2% female, median age 53 years). Approximately half of the sample reported any current substance use with 23.1% reporting single substance use and 21.4% reporting polysubstance use. Polysubstance use was more prevalent among those with current cigarette smoking relative to those with no current smoking and among females relative to males. Alcohol and cannabis were the most commonly reported polysubstance combination; however, a sizeable proportion of PWH reported other two, three, and four-substance groupings. Single and polysubstance use were associated with lower ART adherence. A thorough understanding of substance use patterns and related adherence challenges may aid with targeted public health interventions to improve HIV care cascade goals, including the integration of substance use prevention into HIV treatment and care settings.

RESUMO

Importance: Even with varenicline, the leading monotherapy for tobacco dependence, smoking abstinence rates remain low. Preliminary evidence suggests that extending the duration of varenicline treatment before quitting may increase abstinence. Objective: To test the hypotheses that, compared with standard run-in varenicline treatment (1 week before quitting), extended run-in varenicline treatment (4 weeks before quitting) reduces smoking exposure before the target quit date (TQD) and enhances abstinence, particularly among women. Design, Setting, and Participants: This double-blind, randomized, placebo-controlled clinical trial enrolled participants from October 2, 2017, to December 9, 2020, at a single-site research clinic in Buffalo, New York. Of 1385 people screened, 320 adults reporting smoking 5 or more cigarettes per day (CPD) were randomized and followed up for 28 weeks. Data were analyzed from August 2021 to June 2022. Interventions: In the pre-TQD period (weeks 1-4), the extended run-in group received 4 weeks of varenicline; the standard run-in group received 3 weeks of placebo followed by 1 week of varenicline. Both groups received open-label varenicline during weeks 5 to 15 and brief quit counseling at 6 clinic visits. Main Outcomes and Measures: The primary outcome consisted of cotinine-verified (at end of treatment [EOT]) self-reported continuous abstinence from smoking (in CPD) during the last 4 weeks of treatment. Secondary outcomes included bioverified self-report of continuous abstinence at the 6-month follow-up and percentage of reduction in self-reported smoking rate during the prequit period (week 1 vs week 4). Results: A total of 320 participants were randomized, including 179 women (55.9%) and 141 men (44.1%), with a mean (SD) age of 53.7 (10.1) years. Continuous abstinence during the final 4 weeks of treatment (weeks 12-15; EOT) was not greater in the extended run-in group (64 of 163 [39.3%]) compared with the standard run-in group (57 of 157 [36.3%]; odds ratio [OR], 1.13 [95% CI, 0.72-1.78]), nor was the hypothesized group × sex interaction significant (OR, 0.52 [95% CI, 0.21-1.28]). Similar nonsignificant results were obtained for continuous abstinence at the 6-month follow-up. The mean (SE) decrease in self-reported smoking rate during the prequit period was greater in the extended run-in group (-38.8% [2.8%]) compared with the standard run-in group (-17.5% [2.7%]). Conclusions and Relevance: Among adult daily smokers, extending the duration of prequit varenicline treatment beyond the standard 1-week run-in period reduced prequit smoking exposure but, more importantly, did not significantly improve continuous abstinence rates.

RESUMO

BACKGROUND: Smoking contributes to significant morbidity and mortality in people with HIV. People with HIV have relatively high nicotine metabolism rates, as measured by the nicotine metabolite ratio (NMR, 3-hydroxycotinine/cotinine). A higher NMR is associated with difficulty quitting smoking. We hypothesized that HIV infection might upregulate nicotine metabolism. SETTING: A retrospective study of male current smokers in the Multicenter AIDS Cohort Study who HIV seroconverted between 1985 and 1993. METHODS: Eligibility included having plasma stored before and after confirmed HIV seroconversion and current tobacco use. Samples were selected from the closest available visits before (median 3.3 months) and after (median 9.4 months) seroconversion. Antiretroviral therapy use was exclusionary. Cotinine and 3-hydroxycotinine were measured using liquid chromatography-tandem mass spectrometry. We compared NMR from plasma pre-HIV and post-HIV infection using signed-rank tests. We targeted a sample size of 71 pairs to achieve 80% power to detect a 0.1 unit increase in NMR with P = 0.05. RESULTS: We analyzed paired samples from 78 participants; the median age was 34.5 years [interquartile range (IQR 29-40 years)]. The median NMR pre-HIV and post-HIV was 0.45 (IQR 0.32-0.54) and 0.46 (IQR 0.34-0.56), respectively. The median change in NMR postseroconversion was +0.01 (IQR -0.05, +0.09), P = 0.25. Stratification of median change in NMR by timing between samples or time since HIV seroconversion did not alter this finding. CONCLUSIONS: Acquiring HIV had no measurable effect on NMR. We postulate that upregulation of the NMR may be due to direct pharmacologic effects of HIV medications or metabolic changes in response to HIV infection.

RESUMO

BACKGROUND: Cannabis is increasingly used for symptom management, but its effects on health-related quality of life (QoL) have been inconclusive. OBJECTIVES: The goal of the present study was to characterize self-reported symptoms and QoL among patients certified to use medical cannabis. METHODS: These data are from the baseline assessment of a 12-month longitudinal study. The survey assessed certifying conditions, current medications, symptoms and symptom severity. QoL was assessed using the Functional Assessment of Chronic Illness Therapy-Palliative Care (FACIT-Pal) which includes Physical Well-Being (PWB), Social/Family Well-Being (SWB), Emotional Well-Being (EWB), Functional Well-Being (FWB), and the Palliative Care subscale. Higher scores indicated better QoL. RESULTS: Overall, 210 patients (114 female, 92 male, 3 non-binary, 1 refused) completed the survey. The most common certifying conditions were pain (48.6%), anxiety (36.7%), and PTSD (15.7%) and the most common symptoms were anxiety (65.2%), pain (56.7%), sleep disturbance (38.6%), and depression (31.4%). Compared to normative data, this sample reported lower QoL, specifically EWB and SWB scores (i.e., T-Scores<45). Opioid/benzodiazepine/sedative-hypnotic use was associated with lower QoL on all subscales (except SWB and FWB) (ps < 0.05). Greater number of self-reported symptoms and medical conditions were associated with lower QoL (ps < 0.01). CONCLUSION: Despite mixed evidence regarding cannabis' efficacy for anxiety, 36.7% of the current sample were certified by a physician for anxiety. Lower QoL was associated with more self-reported comorbid medical conditions, higher total symptom count, and reported use of an opioid and/or benzodiazepine. Future longitudinal data will provide critical information regarding the trajectory of these symptoms and QoL.

RESUMO

BACKGROUND: People with HIV (PWH) smoke tobacco at much higher rates than the general population. Previous research has shown that PWH have faster nicotine metabolism than HIV-uninfected individuals, which may underlie this disparity, but the cause is unknown. We investigated whether higher nicotine metabolite ratio (NMR; 3-hydroxycotinine:cotinine), a validated biomarker of nicotine metabolism through CYP2A6, was associated with antiretroviral use among HIV-infected smokers. METHODS: We conducted a retrospective cohort study of HIV-positive smokers in the University of Pennsylvania Center for AIDS Research cohort. We compared the NMR before viral suppression (>10,000 copies/mL) and after viral suppression on antiretroviral therapy (<200 copies/mL). We used mixed-effects linear regression to analyze the change in NMR after viral suppression and assessed for effect modification by efavirenz use. RESULTS: Eighty-nine individuals were included in the study. We observed effect modification by efavirenz use (interaction term for efavirenz use, P < 0.001). Among those on nonefavirenz regimens, the mean NMR increased by 0.14 (95% confidence interval: 0.05 to 0.23, P = 0.002). Among those on efavirenz-containing regimens, the mean NMR increased by 0.53 (95% confidence interval: 0.39-0.66, P < 0.001). CONCLUSIONS: We observed a clinically and statistically significant increase in NMR after viral suppression among smokers with HIV, which more than doubled among those on efavirenz-based regimens. Higher NMR among HIV-positive smokers on antiretroviral therapy may help explain the higher rates of tobacco use and lower quit rates among PWH in care. These findings suggest that regimen choice and other modifiable factors may be targets for future attempts to increase success rates for tobacco cessation among PWH.

RESUMO

PURPOSE: Research eliciting patients' illness concerns has typically focused later in the cancer continuum, rather than during cancer treatments. Family caregiver concerns are overlooked during this time. Less is known about how patients and caregivers prioritize concerns during cancer treatments, which holds potential for improving supportive oncology care (ie, primary palliative care). The purpose of this study was to elicit and compare which domains of supportive oncology are of highest importance to patients and caregivers during cancer treatments. METHODS: Freelisting, a cognitive anthropology method, was used to elicit concerns in order of importance. Freelist data were analyzed using Smith's salience index. Qualitative interviews were conducted with a caregiver subsample to add explanatory insights. RESULTS: In descending order, pain, death, fear, family, and awful were salient Freelist items for patients (n = 65), whereas sadness, time-consuming, support, anger, tired, death, and frustration were salient for caregivers (n = 24). When integrated with supportive oncology domains, patients' concerns reflected a prioritization of the physical (pain) and emotional (death, fear, and awful) domains, with less emphasis on social (family) aspects. Caregivers' prioritized the emotional (sadness, anger, death, and frustration) and social (time-consuming and support) domains, with less emphasis on the physical (tired) aspects. CONCLUSION: Our findings suggest that enhancing primary palliative care delivery by oncology teams requires systems thinking to support both the patient and caregiver as the primary unit of care. Primary palliative care may be improved by prioritizing interventions that address physical concerns among patients as well as key social concerns among caregivers to support the complex caregiving role while patients undergo cancer treatments.

RESUMO

The current study sought to evaluate whether psychological and/or behavioral health moderate the relationship between caregiving and physical health. MATERIALS AND METHODS: Using data from the Behavioral Risk Factor Surveillance System (BRFSS) survey (2017-2018), separate composite scores were created for psychological and behavioral health. Self-reported physical health was the primary outcome. The sample was 1,387 non-caregivers and 266 caregivers. RESULTS: The psychological, behavioral, and self-reported physical health did not significantly differ between caregivers and non-caregivers, but psychological and behavioral health were shown to differentially affect self-reported health outcomes among caregivers, compared to non-caregivers. Caregivers with worse psychological health had higher odds of experiencing poor physical health versus non-caregivers, while caregivers with better behavioral health had lower odds of having better general health versus non-caregivers. DISCUSSION: These data extend our understanding on how to consider the impact of psychological and behavioral health as a caregiver and opportunities to develop targeted interventions.
