Food Addiction and Tobacco Use Disorder: Common Liability and Shared Mechanisms.

As food addiction is being more commonly recognized within the scientific community, parallels can be drawn between it and other addictive substance use disorders, including tobacco use disorder. Given that both unhealthy diets and smoking are leading risk factors for disability and death, a greater understanding of how food addiction and tobacco use disorder overlap with one another is necessary. This narrative review aimed to highlight literature that investigated prevalence, biology, psychology, and treatment options of food addiction and tobacco use disorder. Published studies up to August 2020 and written in English were included. Using a biopsychosocial lens, each disorder was assessed together and separately, as there is emerging evidence that the two disorders can develop concurrently or sequentially within individuals. Commonalities include but are not limited to the dopaminergic neurocircuitry, gut microbiota, childhood adversity, and attachment insecurity. In addition, the authors conducted a feasibility study with the purpose of examining the association between food addiction symptoms and tobacco use disorder among individuals seeking tobacco use disorder treatment. To inform future treatment approaches, more research is necessary to identify and understand the overlap between the two disorders.

Physicians' knowledge and practices regarding screening adult patients for adverse childhood experiences: a survey.

BACKGROUND: Adverse Childhood Experiences (ACEs) are common and associated with many illnesses. Most physicians do not routinely screen for ACEs. We aimed to determine if screening is related to knowledge or medical specialty, and to assess perceived barriers. METHODS: Physicians in Ontario, Canada completed an online survey in 2018-2019. Data were analyzed in 2019. RESULTS: Participants were 89 family physicians, 46 psychiatrists and 48 other specialists. Participants screened for ACEs "never or not usually" (N = 58, 31.7%), "when indicated" (N = 67, 36.6%), "routinely" (N = 50, 27.3%) or "other" (N = 5, 2.7%). Screening was strongly associated with specialty (Chi2 = 181.0, p < .001). The modal responses were: family physicians - "when indicated" (66.3%), psychiatrists - "routinely" (91.3%), and other specialists - "never or not usually" (77.1%). Screening was not related to knowledge of prevalence of ACEs, or of the link between ACEs and mental health, but was significantly associated with knowing that ACEs are associated with physical health. Knowing that ACEs are linked to stroke, ischemic heart disease, COPD, and diabetes predicted greater screening (Chi2 15.0-17.7, each p ≤ .001). The most prevalent perceived barriers to screening were lack of mental health resources (59.0%), lack of time (59.0%), concern about causing distress (49.7%) and lack of confidence (43.7%). CONCLUSIONS: Enhancing knowledge about ACEs' negative influence on physical illness may increase screening. Efforts to promote screening should address concerns that screening is time-consuming and will increase referrals to mental health resources. Education should focus on increasing confidence with screening and with managing patient distress.

Exposure to attachment figure cue reduces cigarette craving.

Cue-induced craving among smokers is a well-documented phenomenon. Conditioning theory is used to explain how stimuli elicit cravings. Attachment theory may explain additional influences on cue-induced craving. This study tested the effects of cigarette cues and attachment figure cues on craving and affect. Cue-reactivity as a function of cue type was examined to explore the magnitude of craving effect sizes for each cue type. Thirty-six smokers (27 men) were exposed to cigarette cues (i.e., cigarette) and attachment figure cues (i.e., digital photos of people identified as attachment figures). Neutral to cue exposure differences in craving and affect were assessed. Sixty-one percent of participants reported increased craving to the cigarette cue (M = 61.1, SD = 29.4) compared to the neutral cue (M = 46.6, SD = 28.8), Mdiff = 20.7 (10.60, 30.73), Yt (23) = 4.24, p = .0003. When exposed to an attachment figure photo, 56% participants reported decreased craving (M = 38.2, SD = 31.6) compared to the neutral photo (M = 50.9, SD = 29.8), Mdiff = -15.73 (-30.83, -0.63), Yt (21) = -2.17, p = .042. There was a significant difference in the craving for cigarette cues (M = 14.5, SD = 22.8 (CI: 6.94, 22.39)), and attachment figure photos (M = -12.7, SD = 28.6 (CI: -22.38, -3.01); t(35) = 4.3, p < .001). The effect sizes for cigarette cues and attachment figure photos were d = .50, d = .42, respectively. Participants' responses to attachment cues were not influenced by their reactivity to cigarette cues or their attachment figure's smoking status. Findings support a plausible model in which an attachment figure photo decreases craving via affect regulation. Further research on cues that have an inhibitory effect on craving may inform new cessation strategies. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

Childhood Adversities and Physical and Mental Health Outcomes in Adults Living with HIV: Findings from the Ontario HIV Treatment Network Cohort Study.

We sought to estimate the prevalence of childhood adversity and examine its relationship with health outcomes among people living with HIV. Study participants included 1409 adults living with HIV and receiving care in Toronto, Canada. Data on childhood adversity, health behaviors, HIV outcome measures, depression, and health-related quality of life (HRQOL) were collected through face-to-face interviews and medical records. Statistical analyses included multivariable linear and logistic regression modeling. The prevalence of any childhood adversity was 71% (individual types ranged from 11% to 44%) and higher prevalence was associated with younger age, Indigenous or African/Caribbean/Black ethnicity, lower socioeconomic status, and higher rates of cigarette smoking and nonmedicinal drug use. Greater number of childhood adversities was associated with greater odds of depression and decreasing mental HRQOL. HIV care providers need to screen for childhood adversities and address childhood trauma within the context of HIV care.

Recovery of respiratory gas exchange after exercise in adults with congenital heart disease.

BACKGROUND: Delayed gas exchange kinetics in the early recovery period after exercise testing has been reported in children and adults with congenital heart disease (ACHD). Our objective was to compare early and late phase recovery kinetics in three groups of ACHD-patients. METHODS: Sixty-seven adults with complex ACHD (33 repaired tetralogy of Fallot, 19 Fontan operations, and 15 transposition complexes) and 10 healthy controls underwent symptom-limited cardiopulmonary exercise testing measuring gas-exchange kinetics over a 10 minute recovery period. Changes within the first minute of recovery and late changes, characterized as the time to reach 50% of peak values (T1/2), were compared between groups. RESULTS: Recovery of VO2 in early and late recoveries was significantly delayed in all ACHD-patients compared to controls without significant differences between patient groups. VO2-recovery at 1 min compared between patients and controls was -7.2 ± 4.0 versus -17.0 ± 4.5 ml · kg · min(-1) and T1/2 VO2 was 147 ± 62 versus 66 ± 23 s (p < 0.0001 for both comparisons). Similar changes were observed for VCO2-recovery. Peak VO2 (ml · kg · min(-1)) demonstrated strong correlation with VO2-recovery at 1 min (ml · kg · min(-1), r=0.90) and moderate correlation with T1/2 VO2 (r = -0.70). CONCLUSION: Gas exchange recovery after exercise testing is prolonged in ACHD-patients, independent of the congenital heart lesion but related to peak aerobic capacity, particularly recovery kinetics within the first minute. Recovery kinetics at 1 min is a useful and easily obtained clinical measure that warrants further study as a prognostic measure.
