Effectiveness of smoking cessation interventions among persons with cancer: A systematic review.

OBJECTIVES: Continued smoking after cancer diagnosis is associated with worse outcomes, however, many persons diagnosed with cancer who smoke are unable to quit successfully. Effective interventions are needed to promote quitting in this population. The purpose of this systematic review is to understand the most effective interventions for smoking cessation among persons with cancer and to identify gaps in knowledge and methodology to suggest directions for future research. METHODS: Three electronic databases (The Cochrane Central Register of Controlled trials, MEDLINE, and EMBASE) were searched for studies of smoking cessation interventions among persons with cancer, published up to 1 July 2021. Title and abstract screening, full-text review, and data extraction was completed by two independent reviewers, via Covalence software, with any discordance resolved by a third reviewer. A quality assessment was completed using the Cochrane Risk of Bias Tool Version 2. RESULTS: Thirty-six articles were included in the review, including 17 randomized-controlled trials (RCTs) and 19 non-RCT studies. Of the 36 studies, 28 (77.8%) utilized an intervention that included both counseling and medication, with 24 (85.7%) providing medication to participants at no cost. Abstinence rates in the RCT intervention groups (n = 17) ranged from 5.2% to 75%, while the non-RCTs found abstinence rates ranging from 15% to 46%. Overall, studies met a mean of 2.28 out of seven quality items, ranging from 0 to 6. CONCLUSIONS: Our study highlights the importance of utilizing intensive combined behavioral and pharmacological interventions for persons with cancer. While combined therapy interventions seem to be the most effective, more research is needed, as current studies have several quality issues, including the lack of biochemical verification for abstinence.

Characterization of TMC-1 in C. elegans sodium chemotaxis and sodium conditioned aversion.

BACKGROUND: While sodium is attractive at low and aversive at high concentrations in most studied species, including Caenorhabditis elegans, the molecular mechanisms behind transduction remain poorly understood. Additionally, past studies with C. elegans provide evidence that the nematode's innate behavior can be altered by previous experiences. Here we investigated the molecular aspects of both innate and conditioned responses to salts. Transmembrane channel-like 1 (tmc-1) has been suggested to encode a sodium-sensitive channel required for sodium chemosensation in C. elegans, but its specific role remains unclear. RESULTS: We report that TMC-1 is necessary for sodium attraction, but not aversion in the nematode. We show that TMC-1 contributes to the nematode's lithium induced attraction behavior, but not potassium or magnesium attraction thus clarifying the specificity of the response. In addition, we show that sodium conditioned aversion is dependent on TMC-1 and disrupts not only sodium induced attraction, but also lithium. CONCLUSIONS: These findings represent the first time a role for TMC-1 has been described in sodium and lithium attraction in vivo, as well as in sodium conditioned aversion. Together this clarifies TMC-1's importance in sodium hedonics and offer molecular insight into salt chemotaxis learning.

Characterizing Tobacco Usage in Otolaryngology Patients to Target Smoking Cessation Efforts.

Objective: Smoking cessation is critical in reducing incidence of head and neck cancers (HNC) and improving postoperative outcomes. Accurate documentation of tobacco usage is necessary to understand prevalence in patients to target smoking cessation. This study aims to characterize tobacco usage documentation, including electronic nicotine delivery systems (ENDS) use, among otolaryngology patients. Study Design: Retrospective chart review. Setting: Penn State Health Milton S. Hershey Medical Center (PSHMC). Methods: A retrospective chart review was conducted on adult otolaryngology patients seen from January 1, 2020 - December 31, 2020. Patient demographics, details of alcohol and tobacco usage, including type of tobacco, and subspecialty seen were collected. Associations were evaluated using chi-square tests and a multivariable logistic regression model. Results: Patients (n = 2137) were an average of 58.4 years old ±18.0, 59.3% female, and 78.0% white. Of participants with documented tobacco history (n = 944), 56.7% were never users, 28.9% were former users, and 14.4% were current users. Among current users (n = 308), 86.4% used cigarettes, and 5.2% used ENDS. The remainder used chew (4.9%) and cigars (3.25%). Odds of tobacco use were 1.5x greater for males (95% CI 1.19-2.00), 1.6x greater for unmarried patients (95% CI 1.24-2.09), 2.1x greater for those with no insurance vs government (95% CI 1.43-3.18), and 2.4x greater for those diagnosed with HNC (95% CI 1.64-3.49). Conclusion: Most patients report cigarette smoking when asked about tobacco use. Taking into consideration the rise of ENDS use, our sample showed ENDS use that was higher than the national average. There is significant opportunity for improved history taking, especially within general and head and neck oncology subspecialties for more comprehensive treatment.

A Systematic Review on the Potential of Aspirin to Reduce Cardiovascular Risk in Schizophrenia.

Cardiovascular disease (CVD), including heart disease and stroke, continues to be the leading cause of death worldwide. Patients with mental health disorders, including schizophrenia (SCZ) are known to have an increased risk for CVD. Given the association with metabolic syndrome, patients with SCZ are often prescribed metformin and statins but its impact remains unsatisfactory. The use of aspirin (ASA) to decrease cardiovascular risk in the general population has been thoroughly investigated and clear guidelines are currently in place. Since adjuvant treatment with ASA could possibly decrease CVD risk and mortality in SCZ, we conducted a systematic review of the literature to determine the state of the current literature on this subject. Our systematic review points to gaps in the literature on CVD prevention in SCZ and illustrates an obvious need for further research. Although several studies have shown increased CVD risk in SCZ, to date, no research has been conducted on the utilization of CVD preventative treatment such as ASA for SCZ.

Burden of cancer in the general surgical population in the eastern region of Ghana.

OBJECTIVE: To estimate the surgical burden of malignant disease in the Eastern Region of Ghana. DESIGN: Descriptive cross-sectional study. SETTING: Regional hospital in the eastern region of Ghana. PARTICIPANTS: Patients treated by the surgery department at Eastern Regional Hospital in Koforidua, Ghana. INTERVENTIONS: None. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcome was incidence of malignancy and secondary outcome descriptive differences between patients who had a benign indication for surgery compared with those with a malignant indication for surgery. RESULTS: A total of 1943 inpatient surgical procedures were performed from 2015 to 2017 with 13.4% (261) of all procedures ultimately performed for malignancy. Of all breast procedures performed, 95.2% of procedures resulted in a malignant diagnosis. The remaining subtypes of procedures had rates ranging from <1% to 41.2% of procedures performed for malignant disease. Additionally, this study found over 13% of patients admitted to the surgical service for breast cancer ultimately did not undergo a surgical procedure. CONCLUSION: This is the first study investigating the burden of malignant disease in the Eastern Region of Ghana. We found a substantial prevalence of malignant disease in the surgical population in this region. This information can be used to aid in future medical resource planning in this region.
