Effects of acute smoking abstinence among people with schizophrenia: A systematic review and meta-analysis of laboratory studies.

BACKGROUND: Smoking rates in schizophrenia are exceptionally high; however, cessation rates remain low with limited research on effective interventions. A critical component of intervention development is identifying the effects of abstinence that are most salient and therefore may contribute to lapse and relapse. OBJECTIVES: We conducted a systematic review and meta-analysis of controlled laboratory studies investigating acute smoking abstinence effects among people with schizophrenia and schizoaffective disorder. METHODS: This review is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. OVID (MEDLINE, EMBASE, PsycINFO) and PubMed databases were searched from inception until November 2023. RESULTS: We identified (k = 16) articles meeting inclusion criteria; all assessed smoking abstinence (ranging 2-120 h). Acute abstinence resulted in large increases in reward-oriented craving and moderate increases in relief-oriented craving; these effects were greater in studies with longer abstinence duration (high certainty). We also observed significant increases in negative affect and global withdrawal symptoms, as well as memory disruption (moderate certainty). Qualitative synthesis suggests restlessness, irritability, anxiety, and visuospatial working memory may be additionally impacted. Findings with respect to negative symptoms and movement were mixed. CONCLUSIONS: Reward-oriented craving may constitute a key target of smoking cessation interventions for people with schizophrenia. In addition, identification of pharmacological and psychosocial interventions that address abstinence-induced changes in relief-oriented craving, memory, negative affect, restlessness, irritability, and anxiety may strengthen treatment outcomes.

How Racialized Approaches to Opioid Use Disorder and Opioid Misuse Management Hamper Pharmacoequity for Cancer Pain.

@JCO_ASCO paper focuses on racialized approaches to OUD and opioid misuse as underappreciated drivers of disparities in cancer and recs a path forward.

Association of smoking with neurocognition, inflammatory and myeloid cell activation profiles in people with HIV on ART.

OBJECTIVE: People with HIV (PWH) experience excess comorbidities, including neurocognitive disorders, which are linked to inflammation, particularly monocyte-macrophage activation. Smoking contributes to morbidity and mortality in well-treated PWH. We investigated associations between smoking, neurocognitive function, and inflammation in PWH on ART. DESIGN: We used baseline data on cognition and inflammation from a longitudinal study of virologically-suppressed PWH who do and do not smoke. METHODS: Participants completed 4 neurocognitive tests (7 measures), with a composite score as the primary measure. Inflammatory markers were plasma sCD14, sCD163, and CCL2/MCP-1; %CD14+ monocytes expressing CD16, CD163, and CCR2; and %CD8+ T cells co-expressing CD38/HLA-DR. Exploratory analyses included a plasma cytokine/chemokine panel, neurofilament light chain (NFL), hsCRP and monocyte transcriptomes by RNAseq. RESULTS: We recruited 58 PWH (26 current smoking [PWH/S], 32 no current smoking [PWH/NS]). Mean composite and individual neurocognitive scores did not differ significantly by smoking status except for the color shape task; PWH/S exhibited worse cognitive flexibility, with adjusted mean times 317.2 (95%CI 1.4, 632.9) msec longer than PWH/NS. PWH/S had higher plasma sCD14 than PWH/NS (median(IQR) 1820(1678, 2105) versus 1551(1284, 1760) ng/ml, p=0.009). Other inflammatory markers were not significantly different between PWH/S and PWH/NS. Monocyte transcriptomes showed several functions, regulators and gene sets that differed by smoking status. CONCLUSIONS: sCD14, a marker of monocyte activation, is elevated in PWH who smoke. While neurocognitive measures and other inflammatory markers did not generally differ, these data implicate smoking-related myeloid activation and monocyte gene dysregulation in the HIV/smoking synergy driving HIV-associated comorbidities.

Cannabis and opioid perceptions, co-use, and substitution among patients across 4 NCI-Designated Cancer Centers.

Prescription opioids are used for managing pain in persons with cancer, however, there are socioeconomic and racial disparities in medication access. Cannabis is increasingly used for cancer symptom management and as an opioid alternative. Limited data are available about patterns of opioid and cannabis use among patients with cancer. We used survey data from 4 National Cancer Institute-designated cancer centers in 3 states (n = 1220) to assess perceptions, use of cannabis and opioids for pain, their substitution, and racial and ethnic differences in each outcome. Compared with White patients, Black patients were less likely to use opioids for pain (odds ratio [OR] = 0.66; P = .035) and more likely to report that cannabis was more effective than opioids (OR = 2.46; P = .03). Race effects were mitigated (P > .05) after controlling for socioeconomic factors. Further research is needed to understand cannabis and opioid use patterns and how overlapping social determinants of health create a disadvantage in cancer symptom management for Black patients.

Tobacco-cannabis co-use among cancer patients and survivors: findings from 2 US cancer centers.

BACKGROUND: Cannabis use is prevalent among cancer patients and survivors and may provide some therapeutic benefits for this population. However, benefits may be attenuated when cannabis is co-used with tobacco, which is associated with more severe tobacco and cannabis use and adverse outcomes in noncancer populations. We compared cannabis use, primary mode of use, and therapeutic and/or nontherapeutic use among 3 groups of patients and survivors based on cigarette smoking status. METHODS: Survey data was collected from patients and survivors with cancer (n = 1732) at 2 US National Cancer Institute-designated cancer centers in states with varying cannabis regulatory policy. Prevalence of cannabis use (prior to diagnosis, after diagnosis, before treatment, after treatment), primary mode of use, and therapeutic and/or nontherapeutic use were assessed by cigarette smoking status (current, former, never) within and across centers using weighted bivariate analyses and multivariable logistic regression, controlling for demographic and clinical variables. RESULTS: Current cigarette use was associated with greater rates of cannabis use prior to diagnosis, after diagnosis, during treatment, and after treatment within each center (all P < .001) and in pooled analyses across centers (all P < .001). Primary mode of use, knowledge of cannabis products, and therapeutic and/or nontherapeutic use also statistically differed by tobacco status and study site. CONCLUSIONS: Results illustrate the importance of conducting assessments for both tobacco and cannabis use among cancer patients during and after cancer treatment, regardless of the cannabis regulatory environment. Given previous data indicating harms from co-use and continued tobacco use during cancer treatment, this issue introduces new priorities for cancer care delivery and research.

Perceptions, prevalence, and patterns of cannabis use among cancer patients treated at 12 NCI-Designated Cancer Centers.

BACKGROUND: The legal climate for cannabis use has dramatically changed with an increasing number of states passing legislation legalizing access for medical and recreational use. Among cancer patients, cannabis is often used to ameliorate adverse effects of cancer treatment. Data are limited on the extent and type of use among cancer patients during treatment and the perceived benefits and harms. This multicenter survey was conducted to assess the use of cannabis among cancer patients residing in states with varied legal access to cannabis. METHODS: A total of 12 NCI-Designated Cancer Centers, across states with varied cannabis-access legal status, conducted surveys with a core questionnaire to assess cannabis use among recently diagnosed cancer patients. Data were collected between September 2021 and August 2023 and pooled across 12 cancer centers. Frequencies and 95% confidence intervals for core survey measures were calculated, and weighted estimates are presented for the 10 sites that drew probability samples. RESULTS: Overall reported cannabis use since cancer diagnosis among survey respondents was 32.9% (weighted), which varied slightly by state legalization status. The most common perceived benefits of use were for pain, sleep, stress and anxiety, and treatment side effects. Reported perceived risks were less common and included inability to drive, difficulty concentrating, lung damage, addiction, and impact on employment. A majority reported feeling comfortable speaking to health-care providers though, overall, only 21.5% reported having done so. Among those who used cannabis since diagnosis, the most common modes were eating in food, smoking, and pills or tinctures, and the most common reasons were for sleep disturbance, followed by pain and stress and anxiety with 60%-68% reporting improved symptoms with use. CONCLUSION: This geographically diverse survey demonstrates that patients use cannabis regardless of its legal status. Addressing knowledge gaps concerning benefits and harms of cannabis use during cancer treatment is critical to enhance patient-provider communication.

Self-reported knowledge of tetrahydrocannabinol and cannabidiol concentration in cannabis products among cancer patients and survivors.

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.

Nicotine Metabolite Ratio Decreases After Switching Off Efavirenz-Based Therapy in People With HIV Who Smoke.

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.

Toward reducing racialized pain care disparities: Approaching cannabis research and access through the lens of equity and inclusion.

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.

Caregiver Engagement in Serious Illness Communication in a Long-Term Acute Care Hospital Setting.

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.

Social Determinants of Health Associated with How Cannabis is Obtained and Used in Patients with Cancer Receiving Care at a Cancer Treatment Center in Pennsylvania.

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.

Changes in Eating Behaviors and Their Relation to Weight Change 6 and 12 Months After Bariatric Surgery.

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.

Clinician Attitudes, Training, and Beliefs About Cannabis: An Interprofessional Assessment.

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.

Substance Use and Adherence to Antiretroviral Therapy among People Living with HIV in the United States.

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.

Effect of Extending the Duration of Prequit Treatment With Varenicline on Smoking Abstinence: A Randomized Clinical Trial.

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. Trial Registration: ClinicalTrials.gov Identifier: NCT03262662.

Characterizing anxiety, pain, sleep, and quality of life among patients in a state Medical Marijuana Program.

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.

Brief Report: Nicotine Metabolism Ratio Increases in HIV-Positive Smokers on Effective Antiretroviral Therapy: A Cohort Study.

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.

Psychological and behavioral moderators of physical health among caregivers and non-caregivers.

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.

"It's Rougher on Me Than It Is on Him": Family Caregiver-Generated and Prioritized Illness Concerns While Patients Undergo Cancer Treatments.

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.
