Menthol and filter ventilation in cigarettes: prevalence estimates and relationships with harm perception and smoking exposure.

INTRODUCTION: Menthol and filter ventilation (FV) contribute to cigarette appeal. This observational study examines the US prevalence of menthol versus non-menthol cigarette use by FV and how harm perceptions, cigarettes per day and biomarkers of exposure vary. METHODS: Population Assessment of Tobacco and Health Study (2013-2014) was merged with FV levels of cigarettes and restricted to daily smoking adults who had a usual cigarette variety and did not regularly use other tobacco (N=1614). Weighted descriptive statistics identified the prevalence of menthol and non-menthol use by low (0.02%-10.04%), moderate (10.05%-23.40%), high (23.41%-28.12%) and very high FV (28.13%-61.10%). Weighted linear regression was used to examine differences in outcomes by menthol/FV adjusted for potential confounders. RESULTS: The prevalence of a usual brand that was non-menthol, low FV was the lowest at 2.91%. Using non-menthol cigarettes with high and very high FV (≥23.4%) vs low FV (≤10.04%) was associated with a greater likeliness of misperceiving one's cigarette variety to be less harmful than other varieties (p values<0.05). Total nicotine equivalent, biomarker for nicotine exposure, was elevated (p values<0.05) among three non-menthol groups (low, moderate and very high FV) compared with two menthol groups (moderate, very high FV). CONCLUSION: The well-documented harm misperception linked to higher FV is more apparent in those using non-menthol than menthol cigarettes. Increased exposures were observed among some non-menthol cigarette users compared with some menthol cigarette users. These results should by no means delay a menthol ban but rather motivate concerted public health efforts to accompany the menthol ban to maximise smoking cessation.

Pilot randomised controlled trial of a culturally aligned smoking cessation app for American Indian persons.

OBJECTIVE: To pilot test QuitGuide for Natives, a culturally aligned version of the National Cancer Institute's QuitGuide smartphone app for smoking cessation. METHODS: This randomised controlled trial was conducted remotely during 2022-2023. American Indian adults who smoked and resided in the Midwest (n=115) were randomised to QuitGuide for Natives or the general audience QuitGuide smartphone-based intervention. Group differences in feasibility (times the app was initiated), usability, acceptability ('How likely would you be to recommend the app to a friend?'), fit of app with culture and preliminary efficacy (24-hour quit attempts, cotinine-confirmed self-reported 7-day abstinence) outcomes were examined. RESULTS: QuitGuide for Natives versus the general audience QuitGuide did not differ in the number of times the app was opened (adjusted incidence rate ratio 0.94 (95% CI 0.63 to 1.40); p=0.743) nor in usability score (adjusted mean difference (aMD) 0.73 (95% CI: -5.00 to 6.46); p=0.801) or likeliness of recommending the app to a friend (aMD 0.62 (95% CI -0.02 to 1.27); p=0.058). Differences were observed for all cultural fit outcomes such as 'The app fits my American Indian culture (aMD 0.75 (95% CI 0.35 to 1.16); p<0.001). QuitGuide for Natives versus the general audience QuitGuide resulted in an average of 6.6 vs 5.1 24-hour quit attempts (p=0.349) and cotinine-confirmed 7-day abstinence was achieved by 6.9% vs 3.5% (p=0.679). CONCLUSIONS: Acceptability, cultural fit and preliminary efficacy findings are encouraging and will inform future, larger-scale evaluation of culturally aligned digital smoking cessation resources for American Indian adults.

Best Practice Alert to Promote Screening for Primary Aldosteronism Among People With Apparent Treatment-Resistant Hypertension.

OBJECTIVE: Guidelines recommend screening all individuals with resistant hypertension for primary aldosteronism (PA) but less than 2% are screened. We aimed to develop a noninterruptive Best Practice Alert (BPA) to assess if its implementation in the electronic health record improved PA screening rates among individuals with apparent treatment-resistant hypertension (aTRH). METHODS: We implemented a noninterruptive BPA on 9/17/2022 at our ambulatory primary care, endocrinology, nephrology, and cardiology clinics. We assessed clinical parameters of people with aTRH before (9/17/2021-9/16/2022) and after (9/17/2022-9/16/2023) the BPA was implemented. The noninterruptive BPA embedded with an order set identified people with aTRH and recommended screening for PA if it was not previously performed. RESULTS: There were 10 944 and 11 463 people with aTRH who attended office visits during the 12 months before and after the BPA implementation, respectively. There were no statistically significant differences in median age (P = .096), sex (P = .577), race (P = .753), and ethnicity (P = .472) between the pre- and post-BPA implementation groups. There was a significant increase in PA screening orders placed (227 [2.1%] vs 476 [4.2%], P < .001) and PA screening labs performed (169 [1.5%] vs 382 [3.3, P < .001) after BPA implementation. PA screening tests were positive in 26% (44/169) and 23% (88/382) of people in the pre- and post-BPA groups, respectively (P = .447). CONCLUSION: Implementation of a real-time electronic health record BPA doubled the screening rate for PA among people with aTRH; however, the overall screening rate was low.

Use of SPY angiography in tissue assessment for wound healing outcomes after breast reconstruction.

OBJECTIVE: The objective of this study was to evaluate whether a systematic image assessment protocol using SPY Elite images (LifeCell Corp., US) of viable tissue at the periphery of the surgical field was associated with positive wound healing outcomes following mastectomy and breast reconstruction. METHOD: Patients undergoing mastectomy and subsequent breast reconstruction surgery at a single tertiary medical centre were included. SPY images were prospectively analysed using a systematic image assessment protocol, and an absolute value of mean fluorescence was calculated by measuring peripheral, in-situ tissue from each image. Patient medical records were retrospectively reviewed for demographics, surgical characteristics and postoperative outcomes. These variables were statistically tested for associations with mean fluorescence. RESULTS: A total of 63 patients were included in the final analysis. We found that objectively determined mean fluorescence values were not statistically significantly associated with postoperative complications. CONCLUSION: In this study, objectively measured mean fluorescence values representing breast tissue remaining after dissection showed little utility in the assessment of postoperative wound healing outcomes as they did not identify patients who would later have complications of wound healing. DECLARATION OF INTEREST: The authors have no conflicts of interest to declare.

Isotope Labeling Mass Spectrometry to Quantify Endogenous and Exogenous DNA Adducts and Metabolites of 1,3-Butadiene In Vivo.

Human exposure to known carcinogen 1,3-butadiene (BD) is common due to its high concentrations in automobile exhaust, cigarette smoke, and forest fires, as well as its widespread use in the polymer industry. The adverse health effects of BD are mediated by epoxide metabolites such as 3,4-epoxy-1-butene (EB), which reacts with DNA to form 1-hydroxyl-3-buten-1-yl adducts on DNA nucleobases. EB-derived mercapturic acids (1- and 2-(N-acetyl-l-cysteine-S-yl)-1-hydroxybut-3-ene (MHBMA) and N-acetyl-S-(3,4-dihydroxybutyl)-l-cysteine (DHBMA)) and urinary N7-(1-hydroxyl-3-buten-1-yl) guanine DNA adducts (EB-GII) have been used as biomarkers of BD exposure and cancer risk in smokers and occupationally exposed workers. However, low but significant levels of MHBMA, DHBMA, and EB-GII have been reported in unexposed cultured cells, animals, and humans, suggesting that these metabolites and adducts may form endogenously and complicate risk assessment of butadiene exposure. In the present work, stable isotope labeling in combination with high-resolution mass spectrometry was employed to accurately quantify endogenous and exogenous butadiene metabolites and DNA adducts in vivo. Laboratory rats were exposed to 0.3, 0.5, or 3 ppm of BD-d6 by inhalation, and the amounts of endogenous (d0) and exogenous (d6) DNA adducts and metabolites were quantified in tissues and urine by isotope dilution capillary liquid chromatography/high resolution electrospray ionization tandem mass spectrometry (capLC-ESI-HRMS/MS). Our results reveal that EB-GII adducts and MHBMA originate exclusively from exogenous exposure to BD, while substantial amounts of DHBMA are formed endogenously. Urinary EB-GII concentrations were associated with genomic EB-GII levels in tissues of the same animals. Our findings confirm that EB-GII and MHBMA are specific biomarkers of exposure to BD, while endogenous DHBMA predominates at sub-ppm exposures to BD.

Transplantation and immigration: Comparing infectious complications and outcomes between foreign-born and US-born kidney transplant recipients in Minnesota.

BACKGROUND: Foreign-born kidney transplant recipients (FBKTRs) are at increased risk for reactivation of latent infections that may impact outcomes. We aimed to compare the etiology of infections and outcomes between FBKTR and United States KTRs (USKTR). METHODS: We performed a retrospective study of patients who underwent kidney transplantation between January 1, 2014 and December 31, 2018 at two transplant centers in Minnesota. Frequency and etiology of infections as well as outcomes (graft function, rejection, and patient survival) at 1-year post-transplant between FBKTR and USKTR were compared. RESULTS: Of the 573 transplant recipients, 124 (21.6%) were foreign-born and 449 (78.4%) US-born. At least one infection occurred in 411 (71.7%) patients (38.2% bacterial, 55% viral, 9.4% fungal). Viral infections were more frequent in FBKTR, particularly BK viremia (38.7% vs. 21.2%, p < .001). No statistical differences were found for bacterial or fungal infections; no parasitic infections were identified in either group. No geographically-restricted infections were noted aside from a single case of Madura foot in a FBKTR. Rejection episodes were more common in USKTR (p = .037), but stable/improving graft function (p = .976) and mortality (p = .451) at 1-year posttransplantation were similar in both groups. After adjusting for covariates, previous transplantation was associated with a higher number of infections (IRR 1.35, 95% confidence intervals 1.05-1.73, p = .020). CONCLUSION: Although viral infections were more frequent in FBKTR, overall frequency and etiology of most infections and outcomes were similar between FBKTR and USKTR suggesting that comprehensive transplant care is providing timely prevention, diagnosis, and treatment of latent infections in FBKTR.

Immediate Switching to Reduced Nicotine Cigarettes in a U.S.-Based Sample: The Impact on Cannabis Use and Related Variables at 20 Weeks.

INTRODUCTION: The FDA proposed rule-making to reduce nicotine in cigarettes to minimally addictive levels. Research suggests decreasing nicotine levels (i.e. very low nicotine content cigarettes [VLNCs]) produced greater quit attempts, reduced smoking, and reduced exposure to harmful constituents among smokers. The impact of long-term VLNC use among people who co-use cigarettes and cannabis on non-tobacco-specific toxicant and carcinogen exposure has not been investigated. AIMS AND METHODS: This study presents secondary analyses of a controlled clinical trial examining switching to VLNC (versus a normal nicotine cigarettes control group [NNCs]) between people who co-use cigarettes and cannabis (n = 174) versus smoked cigarettes (n = 555). Linear mixed-effects models compared changes in smoking behavior, and tobacco-specific (i.e. total nicotine equivalents [TNE], 4-[methylnitrosamino]-1-[3-pyridyl]-1-butanone [NNK; total NNAL]) and non-tobacco-specific (i.e. carbon monoxide (CO), 2-cyanoethylmercapturic acid [CEMA], phenanthrene tetraol [PheT]) toxicant and carcinogen exposure at week 20 (with random intercept for participants). Cannabis use was measured among co-use groups. RESULTS: CO was significantly lower only among the cigarette-only group assigned VLNCs (interaction: p = .015). Although both VLNC groups demonstrated decreased CEMA, greater decreases emerged among the cigarette-only group (interaction: p = .016). No significant interactions emerged for TNE, cigarettes per day (CPD), NNAL, and PheT (ps > .05); both VLNC groups decreased in TNE, CPD, and NNAL. Only the cigarette-only group assigned VLNCs demonstrated decreased PheT (p < .001). The VLNC co-use group showed increased cannabis use over time (p = .012; 0.5 more days per week by week 20). CONCLUSIONS: Those who co-use cannabis and cigarettes may still be at risk for greater exposure to non-tobacco-specific toxicants and carcinogens compared to those who only smoke cigarettes. IMPLICATIONS: The present study is the longest longitudinal, prospective comparison study of smoking behavior and exposure to harmful constituents among those who co-use cigarettes and cannabis versus cigarette-only after immediately switching to very low nicotine content cigarettes (VLNC). Those who co-use experienced similar reductions in CPD and tobacco-specific exposure, compared to those who only use cigarettes. However, co-use groups experienced smaller reductions in non-tobacco-specific toxicants and carcinogens compared to the cigarette-only group, potentially because of combustible cannabis use. Additionally, those who co-use and switched to VLNC may be susceptible to slight increases in cannabis use (approximately two more days per year).

Risk perceptions and continued smoking as a function of cigarette filter ventilation level among US youth and young adults who smoke.

BACKGROUND: While evidence demonstrates that the industry's marketing of cigarettes with higher filter ventilation (FV) misleads adults about their health risks, there is no research on the relationships between FV, risk perceptions and smoking trajectories among youth (ages 12-17) and young adults (ages 18-24). METHODS: Data on FV levels of major US cigarette brands/sub-brands were merged with the Population Assessment of Tobacco and Health Study to examine whether FV level in cigarettes used by wave 1 youth/young adults (n=1970) predicted continued smoking at waves 2-4, and whether those relationships were mediated by perceived risk of their cigarette brand. FV was modelled based on tertiles (0.2%-11.8%, low; 11.9%-23.2%, moderate; 23.3%-61.1%, high) to predict daily smoking, past 30-day smoking and change in number of days smoking at successive waves. RESULTS: The odds of perceiving one's brand as less harmful than other cigarette brands was 2.21 times higher in the high versus low FV group (p=0.0146). Relationships between FV and smoking outcomes at successive waves were non-significant (all p>0.05). CONCLUSION: Youth and young adults who use higher FV cigarettes perceived their brand as less harmful compared with other brands. However, level of FV was not associated with continued smoking.

Qualitative analysis of Doppler assessment used for surveillance of alloimmunized individuals.

OBJECTIVES: To summarize image quality variables for alloimmunized women at risk for fetal anemia. To investigate the association between image quality with the highest and median middle cerebral artery peak systolic velocity (MCA-PSV) at the last visit and fetal anemia based on hemoglobin. STUDY DESIGN: This study was a qualitative retrospective analysis of 192 Doppler ultrasound images used in the detection of fetal anemia in 26 alloimmunized women seen in a Minneapolis hospital over the past 3 years. Images were graded on seven criteria found in literature. RESULTS: Of the images analyzed, 23 (12.0%) of the 192 met all seven image quality criteria. Using the highest MCA-PSV value, the sensitivity, and specificity were 55.6% and 94.1%, respectively. Using the median MCA-PSV value, the sensitivity, and specificity were 44.4% and 94.1%, respectively. CONCLUSIONS: Only a minority of Doppler images meet all suggested image criteria. This could negatively impact the accuracy of the MCA-PSV measurements as indicated by the decreased sensitivity in our evaluations.

Effect of a dementia friends information session on health professional students' attitudes and knowledge related to dementia.

Despite the growing prevalence of dementia, few models of training for health professional students on this topic have been formally evaluated or widely disseminated. The Dementia Friends (DF) initiative is part of a global movement to improve the way people think, act, and talk about dementia. The impact of these sessions on the dementia-related knowledge and attitudes of health professional trainees has not been adequately assessed. Health professional students (medicine n = 70, physical therapy n = 30, pharmacy n = 28) participated in one-hour DF information sessions, offered in-person or via videoconference. The Dementia Attitudes Scale (DAS), a validated 20-item questionnaire, was administered before and after each session. Pre- and post-session DAS scores were compared using a paired t-test. Students' dementia-friendly action plans were analyzed qualitatively. Of 128 students, 102 (80%) completed both the pre- and post-DAS. The mean DAS score increased significantly from 105.8 (12.3) to 120.8 (10.5) following the DF sessions (p < .001). Students' dementia-friendly action plans included improving communication, promoting quality of life, and learning more about dementia. The DF information session model significantly increased the knowledge and positive attitudes of health professional students toward those living with dementia. Further use and study of this model is appropriate.

Preliminary evidence on cigarette nicotine reduction with concurrent access to an e-cigarette: Manipulating cigarette nicotine content, e-liquid nicotine content, and e-liquid flavor availability.

The reinforcing characteristics of e-cigarettes could moderate the impact of reducing cigarette nicotine content. In this study, people who smoke daily were recruited from North Carolina and Pennsylvania (US) in 2018 and 2019. Within a randomized 2 × 2 × 2 factorial design, participants received investigational cigarettes and an e-cigarette for 12 weeks. Cigarette nicotine content was very low (0.4 mg/g of tobacco; VLNC) or normal (15.8 mg/g; NNC). E-liquids were 0.3% ("low") or 1.8% ("moderate") freebase nicotine, and available in tobacco flavors or tobacco, fruit, dessert and mint flavors. Study recruitment concluded before reaching the planned sample size (N = 480). Fifty participants were randomized and 32 completed the study. We found that randomization to VLNC, relative to NNC cigarettes, reduced self-reported cigarettes per day (CPD; mean difference: -12.96; 95% CI: -21.51, -4.41; p = 0.005); whereas e-liquid nicotine content and flavor availability did not have significant effects. The effect of cigarette nicotine content was larger in the moderate vs. low nicotine e-liquid groups and in the all flavors versus tobacco flavors e-liquid groups; tests of the interaction between e-liquid characteristics and cigarette nicotine content were not significant. Biomarkers of smoke exposure at Week 12 did not differ across conditions, which may reflect variability in adherence to only using VLNC cigarettes. In conclusion this study offers preliminary evidence that the extent to which cigarette nicotine reduction decreases smoking may depend on the reinforcing characteristics of alternative products, including the available nicotine contents and flavors of e-cigarettes.

Cigarette Smokers Versus Cannabis Smokers Versus Co-users of Cigarettes and Cannabis: A Pilot Study Examining Exposure to Toxicants.

INTRODUCTION: Studies suggest tobacco and cannabis co-users may experience greater toxicant exposure than exclusive cigarette (ET) smokers. No study has systematically tested differences in toxicant exposure among co-users, exclusive cannabis (ECa) smokers, and ET smokers. AIMS AND METHODS: Adult daily cigarette smokers and/or weekly cannabis smokers completed two laboratory visits. Co-users (n = 19) tested positive for urinary 11-nor-9-carboxy-Δ 9-tetrahydrocannabinol (THCCOOH), self-reported cannabis use ≥1 per week, and smoked ≥5 cigarettes per day (CPD). ET smokers (n = 18) denied past month cannabis use, tested negative for urinary THCCOOH and smoked ≥5 CPD. ECa smokers (n = 16) tested positive for urinary THCCOOH, self-reported cannabis use ≥1 per week, and denied past month tobacco use (NicAlert <3). Self-reported tobacco and cannabis use were collected at both visits. First morning urinary tobacco and combustion-related biomarkers of exposure were compared following a cannabis or tobacco smoking session (visit 2). RESULTS: Co-users and ET smokers had higher levels of exhaled carbon monoxide, total nicotine equivalents, metabolites of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNAL), and all four measured mercapturic acids (measures of volatile organic compounds) than ECa smokers (ps < .005). ET smokers (geometric mean = 7220.2 pmol/mg) had higher levels of 2-hydroxypropylmercapturic acid than co-users (geometric mean = 5348.7 adjusted p = .009). Phenanthrene tetraol did not differ by group (p > .05). CONCLUSIONS: Co-users and ET smokers demonstrated comparable levels of biomarkers of exposure to harmful constituents despite smoking similar amounts of tobacco. ECa smokers demonstrated lower levels of toxicant exposure for most biomarkers. IMPLICATIONS: Although ECa smokers are exposed to significantly lower levels of harmful constituents compared with co-users and exclusive cigarette smokers, this group is still exposed to higher levels of toxicants than observed in studies of nonsmokers. Additionally, these three groups were exposed to similar levels of phenanthrene tetraol. It is important to account for cannabis use in studies examining biomarkers of exposure among cigarette smokers. Additionally, further research is needed examining exposure to harmful chemicals among various types of cannabis and tobacco users.

Screening Rate for Primary Aldosteronism Among Patients With Apparent Treatment-Resistant Hypertension: Retrospective Analysis of Current Practice.

OBJECTIVE: Primary aldosteronism (PA) is the most common secondary cause of hypertension. Patients with PA experience significant cardiovascular and other complications compared with patients with primary hypertension with the same degree of blood pressure control as those with PA. Guidelines have recommended screening all patients with resistant hypertension for PA. The objective of this study was to assess the screening rate for PA among patients with apparent treatment-resistant hypertension and determine the rate of positive screening test result among the group screened. METHODS: This was a retrospective chart review of electronic medical record data of all patients with hypertension aged ≥18 years within a single health system in Minnesota from September 2018 to September 2020. RESULTS: Of 140 734 patients who were aged ≥18 years and had a diagnosis of hypertension, 18 908 (13.4%) met the criteria for apparent treatment-resistant hypertension after those with congestive heart failure were excluded. Only 795 (4.2%) patients with apparent treatment-resistant hypertension underwent screening for PA in our cohort. Of the 795 patients who underwent screening for PA, 134 (16.9%) had a positive screening test result. CONCLUSION: The screening rate for PA among patients with resistant hypertension was low. Clinical and public health strategies directed at improving the screening rate for PA are vital.

Comparing Characteristics of and Postoperative Morbidity after Hysterectomy for Endometriosis versus other Benign Indications: A NSQIP Study.

STUDY OBJECTIVE: Compare the difference in postoperative morbidity for benign total hysterectomy by indication. DESIGN: Retrospective cohort. SETTING: United States hospitals participating in the American College of Surgeons National Surgical Quality Improvement Project database from 2018 to 2019. PATIENTS: Patients undergoing total hysterectomy for benign indications age 18 to 55 years old. INTERVENTIONS: Univariate comparisons were made between patients with hysterectomies for endometriosis and other benign indications. Unadjusted and adjusted logistic regression models were used to investigate the association between primary outcomes and hysterectomy indication; covariates in the adjusted model include age, race, ethnicity, and route. MEASUREMENTS AND MAIN RESULTS: A total of 29 742 women underwent hysterectomies, of which 3596 (12.1%) were performed for endometriosis. Patients undergoing hysterectomy for endometriosis were likely to be younger, were predominately White, and had less comorbidities. They were also more likely to have previous abdominal surgery, have previous pelvic surgery, undergo a laparoscopic approach, and undergo lysis of adhesions (all p <.001). Overall length of stay (≥1 day 73.1% vs 78.6%; p = .983) and operative time (median 118.0 vs 125.0 minutes; p <.001) were similar in both groups. Examining primary outcomes, patients with endometriosis were more likely to experience major morbidity (3.8% vs 3.4%; adjusted odds ratio [OR], 1.25; p = .033), with no difference in minor or overall morbidity (5.8% vs 6.9% [p = .874] and 8.8% vs 9.4% [p = .185], respectively). There were two 30-day mortalities, none in the endometriosis group. Patients with endometriosis were more likely to develop deep surgical site infection (SSI)/organ-space infection (2.3% vs 1.6%; OR, 1.42; p = .024) and less likely to receive blood transfusion (1.8% vs 3.0%; OR, 0.58; p <.001). There was no difference in occurrence of superficial SSI, sepsis, venous thromboembolism, readmission, or reoperation between groups. CONCLUSION: Patients undergoing hysterectomy for endometriosis were more likely to experience major morbidity and deep SSI, although overall major morbidity is rare.

The Impact of Culturally-Centered Care on Peripartum Experiences of Autonomy and Respect in Community Birth Centers: A Comparative Study.

OBJECTIVE: National studies report that birth center care is associated with reduced racial and ethnic disparities and reduced experiences of mistreatment. In the US, there are very few BIPOC-owned birth centers. This study examines the impact of culturally-centered care delivered at Roots, a Black-owned birth center, on the experience of client autonomy and respect. METHODS: To investigate if there was an association between experiences of autonomy and respect for Roots versus the national Giving Voice to Mothers (GVtM) participants, we applied Wilcoxon rank-sum tests for the overall sample and stratified by race. RESULTS: Among BIPOC clients in the national GVtM sample and the Roots sample, MADM and MORi scores were statistically higher for clients receiving culturally-centered care at Roots (MADM p < 0.001, MORi p = 0.011). No statistical significance was found in scores between BIPOC and white clients at Roots Birth Center, however there was a tighter range among BIPOC individuals receiving care at Roots showing less variance in their experience of care. CONCLUSIONS FOR PRACTICE: Our study confirms previous findings suggesting that giving birth at a community birth center is protective against experiences of discrimination when compared to care in the dominant, hospital-based system. Culturally-centered care might enhance the experience of perinatal care even further, by decreasing variance in BIPOC experience of autonomy and respect. Policies on maternal health care reimbursement should add focus on making community birth sustainable, especially for BIPOC provider-owners offering culturally-centered care.

Pelvic organ prolapse and anal incontinence in women: screening with a validated epidemiology survey.

PURPOSE: The primary objective of this study was to determine the prevalence of pelvic organ prolapse (POP) and anal incontinence (AI) in a Minnesota population using the Epidemiology of Prolapse and Incontinence Questionnaire (EPIQ). The secondary objective of this study was to determine the association of POP and AI with parity, age, smoking status, body mass index (BMI), and co-morbidities. METHODS: Women ≥ 18 years old attending the 2018 Minnesota State Fair were asked to fill out a web-based version of the EPIQ. Multivariable logistic regression models were used to investigate the association of POP and AI with the variables of interest. RESULTS: A total of 1426 women were included in the analysis. There was a 4.9% prevalence of POP and 14.9% prevalence of AI. POP was significantly associated with parity and higher BMI (p < 0.01 and p = 0.02, respectively). In this cohort, POP was not associated with older age, smoking, or presence of co-morbid conditions. Anal incontinence was associated with older age (p < 0.01), smoking status (p = 0.01), and presence of co-morbid conditions (p = 0.01) but was not associated with parity or higher BMI. CONCLUSION: POP and AI were associated with some, but not all, of the variables tested, which differs from prior studies. In addition, the prevalence of POP and AI were different than rates reported in similar studies. This may suggest regional differences in prevalence of POP and AI.

Infusion reactions in natural killer cell immunotherapy: a retrospective review.

BACKGROUND AIMS: The use of natural killer (NK) cells as a cellular immunotherapy has increased over the past decade, specifically in patients with hematologic malignancies. NK cells have been used at the authors' institution for over 15 years. Most patients have a reaction to NK cell infusion. The authors retrospectively analyzed the reactions associated with NK cell infusions to characterize the types of reactions and investigate why some patients have higher-grade reactions than others. METHODS: A retrospective chart review of NK cell infusions was performed at the authors' institution under nine clinical protocols from 2008 to 2016. An infusion reaction was defined as any symptom from the time of NK cell infusion up to 4 h after infusion completion. The severity of infusion reactions was graded based on Common Terminology Criteria for Adverse Events, version 4. Two major endpoints of interest were (i) infusion reaction with any symptom and (ii) grade ≥3 infusion reaction. Multivariable logistic regression models were used to investigate the association between variables of interest and outcomes. Odds ratios (ORs) and 95% confidence intervals (CIs) were obtained for each variable. RESULTS: A total of 130 patients were receiving NK cell infusions at the authors' institution. The most common reported symptom was chills (n = 110, 85%), which were mostly grade 1 and 2, with only half of patients requiring intervention. There were 118 (91%) patients with infusion reactions, and only 36 (28%) were grade 3. There was one life-threatening grade 4 reaction, and no death was reported due to infusion reaction. Among grade ≥3 reactions, cardiovascular reactions (mainly hypertension) were the most common, and less than half of those with hypertension required intervention. NK cell dose was not associated with any of the grade 3 infusion reactions, whereas monocyte dose was associated with headache (grade ≤3, OR, 2.17, 95% CI, 1.19-3.97) and cardiovascular reaction (grade ≥3, OR, 2.13, 95% CI, 1.13-3.99). Cardiovascular reaction (grade ≥3) was also associated with in vitro IL-2 incubation and storage time. Additionally, there was no association between grade ≥3 infusion reactions and overall response rate (OR, 0.75, 95% CI, 0.29-1.95). CONCLUSIONS: The majority of patients who receive NK cell therapy experience grade 1 or 2 infusion reactions. Some patients experience grade 3 reactions, which are mainly cardiovascular, suggesting that close monitoring within the first 4 h is beneficial. The association of monocytes with NK cell infusion reaction relates to toxicities seen in adoptive T-cell therapy and needs further exploration.

Testing the Feasibility and Acceptability of a Religiously-Tailored Text Messaging Intervention to Reduce Smoking Among Somali Muslim Men During Ramadan.

INTRODUCTION: The prevalence of smoking among Somali Muslim male immigrants residing in Minnesota is estimated at 44%, however smoking reduction is common during the month of Ramadan. This study evaluated the feasibility and impact of a religiously tailored text message intervention delivered during Ramadan to encourage smoking reduction among Somali Muslim men who smoke. METHODS: Fifty Somali men were recruited. Participants received two text messages per day starting 1 week prior to and throughout the month of Ramadan. Approximately half were religiously tailored and half were about the risks of smoking and benefits of quitting. Smoking behavior was assessed at baseline, and at weeks 4 (end of Ramadan), 8, and 16. Outcomes included feasibility, acceptability, and preliminary impact of the text message intervention on smoking reduction and bioverified abstinence. RESULTS: The average age was 41 years. Average time to first cigarette was 1.8 hours at baseline, and 46% of participants smoked menthol cigarettes. Eighteen of 50 participants selected English and 32 selected Somali text messages. Subjects significantly reduced self-reported cigarettes per day (CPD) from 12.4 CPD at baseline to 5.8 CPD at week 16 (p < 0.001). Seven subjects reported quitting at week 16, five completed CO testing, confirming self-reported abstinence. The majority of participants found the cultural and religious references encouraging at the end of the week 16 survey. CONCLUSIONS: Religiously tailored text messages to decrease smoking are feasible and acceptable to Somali Muslim men who smoke during Ramadan. This intervention for addressing smoking disparities is worthy of further study. IMPLICATIONS: Recruitment of Somali Muslim men who smoke is feasible and supports the idea that further studies targeting smoking during Ramadan are practical. Ramadan presents a window of opportunity upon which to build smoking cessation interventions for smokers who identify as Muslim. These preliminary findings suggest that text messaging is a feasible and acceptable intervention strategy, and that religious tailoring was well received. Such an approach may offer potential for addressing smoking disparities among Somali Muslim male smokers. TRIAL REGISTRATION: ClinicalTrial.gov: NCT03379142.

An Evaluation of Potential Unintended Consequences of a Nicotine Product Standard: A Focus on Drinking History and Outcomes.

INTRODUCTION: A nicotine product standard reducing the nicotine content in cigarettes could improve public health by reducing smoking. This study evaluated the potential unintended consequences of a reduced nicotine product standard by examining its effects on (1) smoking behaviors based on drinking history; (2) drinking behavior; and (3) daily associations between smoking and drinking. METHODS: Adults who smoke daily (n = 752) in the United States were randomly assigned to smoke very low nicotine content (VLNC) cigarettes versus normal nicotine content (NNC; control) cigarettes for 20 weeks. Linear mixed models determined if baseline drinking moderated the effects of VLNC versus NNC cigarettes on Week 20 smoking outcomes. Time-varying effect models estimated the daily association between smoking VLNC cigarettes and drinking outcomes. RESULTS: Higher baseline alcohol use (vs no use or lower use) was associated with a smaller effect of VLNC on Week 20 urinary total nicotine equivalents (ps < .05). No additional moderation was supported (ps > .05). In the subsample who drank (n = 415), in the VLNC versus NNC condition, daily alcohol use was significantly reduced from Weeks 17 to 20 and odds of binge drinking were significantly reduced from Weeks 9 to 17. By Week 7, in the VLNC cigarette condition (n = 272), smoking no longer predicted alcohol use but remained associated with binge drinking. CONCLUSIONS: We did not support negative unintended consequences of a nicotine product standard. Nicotine reduction in cigarettes generally affected smoking behavior for individuals who do not drink or drink light-to-moderate amounts in similar ways. Extended VLNC cigarette use may improve public health by reducing drinking behavior. IMPLICATIONS: There was no evidence that a VLNC product standard would result in unintended consequences based on drinking history or when considering alcohol outcomes. Specifically, we found that a very low nicotine standard in cigarettes generally reduces smoking outcomes for those who do not drink and those who drink light-to-moderate amounts. Furthermore, an added public health benefit of a very low nicotine standard for cigarettes could be a reduction in alcohol use and binge drinking over time. Finally, smoking VLNC cigarettes may result in a decoupling of the daily associations between smoking and drinking.

Preterm Birth of Infants Prenatally Diagnosed with Congenital Heart Disease, Characteristics, Associations, and Outcomes.

There are limited data on the relation between congenital heart disease (CHD) and preterm birth (PTB). We aimed to estimate the risk of PTB in newborns with CHD, to study associations and risk factors (modifiable and non-modifiable) as well as investigate postnatal outcomes. This was a retrospective cohort study of 336 pregnancies diagnosed with CHD between 2011 and 2016. Groups consisted of those delivered at or after 37 weeks, and those who delivered prior to 37 weeks. Collected data included maternal and fetal characteristics as well postnatal outcomes. Complete data were obtained from 237 singleton pregnancies. The overall proportion of PTB was 23.2% for all CHD, of which 38.2% were spontaneous PTB which was almost unchanged after excluding extracardiac anomalies and pathogenic chromosomal abnormalities. Significant non-modifiable risk factors were pregnancy-related HTN disorders (P < 0.001), fetal growth restriction (P = 0.01), and pathogenic chromosomal abnormalities (P = 0.046). Significant PTB modifiable risk factors included prenatal marijuana use (P = 0.01). Pregnancies delivered at 37-38 weeks had significantly more newborns with birthweight < 2500 g (P < 0.001), required more pre-operative NICU support including intubation (P = 0.049), vasopressors (P = 0.04), prostaglandins (P = 0.003), antibiotics (P = 0.01), and had longer hospital stay (P = 0.001) than those delivered at ≥ 39 weeks. Prenatally diagnosed pregnancies with CHD had higher PTB rate compared to the general population, with spontaneous PTB comprising 38.2% of these preterm deliveries. Most PTB risk factors were non-modifiable, however, significant modifiable factors included marijuana use in pregnancy. Outcomes were favorable in neonates delivered at or beyond 39 weeks.
