Telephone-delivered cognitive-behavioral therapy for pain management among older military veterans: a randomized trial.
This study investigated the effectiveness of telephone-delivered cognitive-behavioral therapy (T-CBT) in the management of chronic pain with older military veterans enrolled in VA primary-care clinics. We conducted a randomized clinical trial comparing T-CBT with telephone-delivered pain education (T-EDU). A total of 98 military veterans with chronic pain were enrolled in the study and randomized into one of two treatment conditions. Study participants were recruited from primary-care clinics at an urban VA medical center and affiliated VA community-based outpatient clinics (CBOCs). Pain management outcomes were measured at midtreatment (10 weeks), posttreatment (20 weeks), 3-month follow-up (32 weeks), and 6-month follow-up (46 weeks). No significant differences were found between the two treatment groups on any of the outcome measures. Both treatment groups reported small but significant increases in level of physical and mental health, and reductions in pain and depressive symptoms. Improvements in all primary outcome measures were mediated by reductions in catastrophizing. Telephone-delivered CBT and EDU warrant further study as easily accessible interventions for rural-living older individuals with chronic pain
Expectancies regarding the interaction between smoking and substance use in alcohol-dependent smokers in early recovery.
The purpose of this study was to investigate expectancies regarding the interaction between cigarette smoking and use of alcohol among alcohol-dependent smokers in early recovery, using the Nicotine and Other Substances Interaction Expectancies Questionnaire (NOSIE). Participants were 162 veterans, 97% male, with a mean age of 50 years, enrolled in a clinical trial aimed at determining the efficacy of an intensive smoking cessation intervention versus usual care. At baseline, participants were assessed on measures of smoking behavior, abstinence thoughts about alcohol and tobacco use, symptoms of depression, and smoking-substance use interaction expectancies. In addition, biologically verified abstinence from tobacco and alcohol was assessed at 26 weeks. Participants reported that they expected smoking to have less of an impact on substance use than substance use has on smoking (p < .001). Severity of depressive symptoms was significantly associated with the expectancy that smoking provides a way of coping with the urge to use other substances (p < .01). The expectation that smoking increases substance urges/use was predictive of prospectively measured and biologically verified abstinence from smoking at 26 weeks (p < .03). The results add to our knowledge of smoking-substance use interaction expectancies among alcohol-dependent smokers in early recovery and will inform the development of more effective counseling interventions for concurrent alcohol and tobacco use disorders

Low-Level Laser Therapy Activates NF-kB via Generation of Reactive Oxygen Species in Mouse Embryonic Fibroblasts
Background
Despite over forty years of investigation on low-level light therapy (LLLT), the fundamental mechanisms underlying photobiomodulation at a cellular level remain unclear.
Methodology/Principal Findings
In this study, we isolated murine embryonic fibroblasts (MEF) from transgenic NF-kB luciferase reporter mice and studied their response to 810 nm laser radiation. Significant activation of NF-kB was observed at fluences higher than 0.003 J/cm2 and was confirmed by Western blot analysis. NF-kB was activated earlier (1 hour) by LLLT compared to conventional lipopolysaccharide treatment. We also observed that LLLT induced intracellular reactive oxygen species (ROS) production similar to mitochondrial inhibitors, such as antimycin A, rotenone and paraquat. Furthermore, we observed similar NF-kB activation with these mitochondrial inhibitors. These results, together with inhibition of laser induced NF-kB activation by antioxidants, suggests that ROS play an important role in the laser induced NF-kB signaling pathways. However, LLLT, unlike mitochondrial inhibitors, induced increased cellular ATP levels, which indicates that LLLT also upregulates mitochondrial respiration.
Conclusion
We conclude that LLLT not only enhances mitochondrial respiration, but also activates the redox-sensitive NFkB signaling via generation of ROS. Expression of anti-apoptosis and pro-survival genes responsive to NFkB could explain many clinical effects of LLLT.National Institutes of Health (U.S.) (grant R01AI050875)Center for Integration of Medicine and Innovative Technology (DAMD17-02-2-0006)United States.

Genetic mechanisms of critical illness in COVID-19.
Host-mediated lung inflammation is present1, and drives mortality2, in the critical illness caused by coronavirus disease 2019 (COVID-19). Host genetic variants associated with critical illness may identify mechanistic targets for therapeutic development3. Here we report the results of the GenOMICC (Genetics Of Mortality In Critical Care) genome-wide association study in 2,244 critically ill patients with COVID-19 from 208 UK intensive care units. We have identified and replicated the following new genome-wide significant associations: on chromosome 12q24.13 (rs10735079, P = 1.65 × 10-8) in a gene cluster that encodes antiviral restriction enzyme activators (OAS1, OAS2 and OAS3); on chromosome 19p13.2 (rs74956615, P = 2.3 × 10-8) near the gene that encodes tyrosine kinase 2 (TYK2); on chromosome 19p13.3 (rs2109069, P = 3.98 × 10-12) within the gene that encodes dipeptidyl peptidase 9 (DPP9); and on chromosome 21q22.1 (rs2236757, P = 4.99 × 10-8) in the interferon receptor gene IFNAR2. We identified potential targets for repurposing of licensed medications: using Mendelian randomization, we found evidence that low expression of IFNAR2, or high expression of TYK2, are associated with life-threatening disease; and transcriptome-wide association in lung tissue revealed that high expression of the monocyte-macrophage chemotactic receptor CCR2 is associated with severe COVID-19. Our results identify robust genetic signals relating to key host antiviral defence mechanisms and mediators of inflammatory organ damage in COVID-19. Both mechanisms may be amenable to targeted treatment with existing drugs. However, large-scale randomized clinical trials will be essential before any change to clinical practice
A COMPARATIVE ANALYSIS OF RATIONAL-EMOTIVE SELF-INSTRUCTIONAL AND BEHAVIORAL ASSERTION TRAINING
Reciprocal effects of alcohol and nicotine in smoking cessation treatment studies
ObjectiveSmoking and alcohol use are highly related; as such the present study investigated whether alcohol use is associated with failure in tobacco cessation attempts. We first examined the self-reported drinking behavior and smoking over the course of a year at a basic level. Next, we addressed two hypotheses to characterize this relationship at a deeper level: (Hypothesis 1) Alcohol use would be lower for those who attempted to quit smoking (quit for one or more days) during the year compared to those who never quit, and (Hypothesis 2) for those who relapsed to smoking after a quit increases in alcohol consumption would be positively associated with increases in smoking.MethodSubjects were participants in two smoking cessation programs. One group of participants (N=139) was part of a smoking cessation study in alcohol dependent smokers in early recovery and the other group of participants (N=163) was drawn from a smoking cessation study for HIV positive smokers. H1 was tested using t-tests. For H2, a time series analysis examined relationships between smoking and alcohol use within person over a one year period. For H1 and for H2, the analyses utilized bivariate time series procedures. Timeline follow-back data allowed for detailed daily reports of both tobacco and alcohol use.ResultsIn the overall sample, there was no difference in alcohol use between those who stopped smoking and those who never stopped. However, when broken up by study, a difference was found in the alcohol dependent sample such that mean drinks were higher for those who stopped compared to those who never stopped smoking (H1). The results indicated a high number of positive significant cross-correlations between tobacco and alcohol use such that one substance predicted current, as well as past and future use of the alternate substance. Same-day cross-correlations were the most common, and dissipated with time (H2).ConclusionsThis analysis provided insights into the proximal influence of one substance on the other. Alcohol is related to relapse in smoking cessation attempts. It is important that smoking cessation efforts in alcohol using populations consider alcohol use in treatment

Hypnosis for Smoking Relapse Prevention: A Randomized Trial.
The purpose of this study was to determine whether hypnosis would be more effective than standard behavioral counseling in helping smokers to remain abstinent. A total of 140 current smokers were enrolled in a randomized controlled smoking cessation trial at an urban Veterans Affairs medical center. Participants (n = 102) who were able to quit for at least 3 days received either a hypnosis or behavioral relapse prevention intervention. Both relapse prevention interventions consisted of two 60 min face-to-face sessions and four 20 min follow-up phone calls (two phone calls per week). At 26 weeks, the validate\d point-prevalence quit rate was 35% for the hypnosis group and 42% for the behavioral counseling group (relative risk = 0.85; 95% confidence interval: 0.52-1.40). At 52 weeks, the validated quit rate was 29% for the hypnosis group and 28% for the behavioral group (relative risk = 1.03; 95% confidence interval: 0.56-1.91). It was concluded that hypnosis warrants further investigation as an intervention for facilitating maintenance of quitting
