Preferences for Communicating about Breast Cancer Screening Among Racially/Ethnically Diverse Older Women.

Differences exist across breast cancer screening guidelines regarding frequency of screening and age of discontinuation for older women (≥70 years) at average risk for breast cancer. These differences highlight concerns about the benefits and harms of screening, and may negatively impact older women's ability to make informed screening decisions. This study examined preferences for communicating about screening mammography among racially/ethnically diverse, older women. In-depth interviews were conducted with 59 women with no breast cancer history. Non-proportional quota sampling ensured roughly equal numbers on age (70-74 years, ≥75 years), race/ethnicity (non-Hispanic/Latina White, non-Hispanic/Latina Black, Hispanic/Latina), and education (≤high school diploma, >high school diploma). Interviews were audio-recorded, transcribed, and analyzed using NVivo 10. Thematic analyses revealed that rather than being told to get mammograms, participants wanted to hear about the benefits and harms of screening mammography, including overdiagnosis. Participants recommended that this information be communicated via physicians or other healthcare providers, included in brochures/pamphlets, and presented outside of clinical settings (e.g., in senior groups). Results were consistent regardless of participants' age, race/ethnicity, or education. Findings revealed that older women desire information about the benefits and harms of screening mammography, and would prefer to learn this information through discussions with healthcare providers and multiple other formats.

Lived experiences of chronic cognitive and mood symptoms among community-dwelling adults following stroke: a mixed-methods analysis.

Objectives: Few studies have explored the lived experiences of chronic cognitive and mood symptoms following stroke using a racially/ethnically diverse sample. Therefore, we aimed to explore the perceptions of chronic post-stroke cognition and mood symptoms and goals among a racially/ethnically diverse sample of community-dwelling adults aging with stroke. Method: This qualitative study using mixed-methods analysis included semi-structured interviews regarding perceived post-stroke cognitive and mood symptoms among community-dwelling stroke survivors at least one-year post stroke. Transcripts were subjected to thematic content analysis, and differences in theme usage patterns by age, gender, race/ethnicity, and post-acute rehabilitation setting were assessed using an inferential clustering technique. Results: The majority of participants (93%) reported cognition-related themes, including language and communication, memory, thinking abilities, comprehension, visual-spatial processing, and cognitive assessments and training. Nearly half of participants mentioned mood-related themes, including depression, aggression and anger, mood fluctuations, anxiety, and psychological services and medication. Nearly half reported an unmet need for cognition or mood-related treatment. Inferential clustering analysis revealed that older participants reported a different pattern of cognitive and mood symptoms than those aged younger than 65 (p = 0.02). Older adults were more likely to describe post-stroke language/communication changes, while younger adults described post-stroke mood changes. Conclusion: Stroke survivors experienced cognitive and mood-related symptoms beyond one-year post stroke, which has implications for long-term assessment and management. Incorporation of continued symptom monitoring into existing community-based services is needed to address chronic cognitive and mood symptoms affecting the quality of life of persons with stroke.

Resistance to discontinuing breast cancer screening in older women: A qualitative study.

OBJECTIVE: Screening mammography is associated with reduced breast cancer-specific mortality; however, among older women, evidence suggests that the potential harms of screening may outweigh the benefits. We used a qualitative approach to examine the willingness of older women from different racial/ethnic groups to discontinue breast cancer screening. METHODS: Women ≥70 years of age who reported having a screening mammogram in the past 3 years and/or reported that they intended to continue screening in the future were recruited for in-depth interviews. Participants who intended to continue screening were asked to describe how the following hypothetical scenarios would impact a decision to discontinue screening: health concerns or limited life expectancy, a physician's recommendation to discontinue, reluctance to undergo treatment, and recommendations from experts or governmental panels to stop screening. Semi-structured, face-to-face interviews were audio-recorded. Data coding and analysis followed inductive and deductive approaches. RESULTS: Regardless of the scenario, participants (n = 29) expressed a strong intention to continue screening. Based on the hypothetical physician recommendations, intentions to continue screening appeared to remain strong. They did not envision a change in their health status that would lead them to discontinue screening and were skeptical of expert/government recommendations. There were no differences observed according to age, race/ethnicity, or education. CONCLUSIONS: Among older women who planned to continue screening, intentions to continue breast cancer screening appear to be highly resilient and resistant to recommendations from physicians or expert/government panels.

Patient and physician views of shared decision making in cancer.

CONTEXT: Engaging patients in shared decision making involves patient knowledge of treatment options and physician elicitation of patient preferences. OBJECTIVE: Our aim was to explore patient and physician perceptions of shared decision making in clinical encounters for cancer care. DESIGN: Patients and physicians were asked open-ended questions regarding their perceptions of shared decision making throughout their cancer care. Transcripts of interviews were coded and analysed for shared decision-making themes. SETTING AND PARTICIPANTS: At an academic medical centre, 20 cancer patients with a range of cancer diagnoses, stages of cancer and time from diagnosis, and eight physicians involved in cancer care were individually interviewed. DISCUSSION AND CONCLUSIONS: Most physicians reported providing patients with written information. However, most patients reported that written information was too detailed and felt that the physicians did not assess the level of information they wished to receive. Most patients wanted to play an active role in the treatment decision, but also wanted the physician's recommendation, such as what their physician would choose for him/herself or a family member in a similar situation. While physicians stated that they incorporated patient autonomy in decision making, most provided data without making treatment recommendations in the format preferred by most patients. We identified several communication gaps in cancer care. While patients want to be involved in the decision-making process, they also want physicians to provide evidence-based recommendations in the context of their individual preferences. However, physicians often are reluctant to provide a recommendation that will bias the patient.

Afghan Refugee Explanatory Models of Depression: Exploring Core Cultural Beliefs and Gender Variations.

Relatively little empirical attention has been paid to understanding how refugees conceptualize depression and how this concept varies between genders. The purpose of this study was to explore beliefs about depression among Afghans residing in San Diego County, California, using cultural consensus analysis. Using the prescribed mixed-method approach, we employed results from in-depth interviews to develop a culturally meaningful questionnaire about depression. Consensus analysis of responses to questionnaire items from 93 Afghans (50 men, 43 women) indicates shared beliefs that associates depression causality with mild traumatic experiences and post-resettlement stressors, symptomatology to include culturally salient idioms of distress, and treatment selections ranging from lay techniques to professional care. Divergence between genders occurred most in the symptoms subdomain, with women associating depression with more somatic items. This study contributes to understanding the etiology of and cultural responses to depression among this population, which is critical to improving culturally sensitive intervention for Afghan refugees.

Does hormone therapy exacerbate other venous thromboembolism risk factors?

OBJECTIVE: Postmenopausal symptoms in women at higher risk for venous thromboembolism (VTE) due to comorbidities are often undertreated because of concerns that hormone therapy (HT) may increase VTE risk; however, it is unclear how much HT impacts risk of VTE when compared with other risk factors. METHODS: This is a case-control study in a commercial claims database from 2007 to 2019. Women aged 50 to 64 years (n = 223,949) were classified as cases if they had an International Classification of Diseases code indicating an acute VTE plus a filled prescription for an anticoagulant, placement of intravascular vena cava filter, or death within 30 days of diagnosis. Controls were matched 10:1 to each case by index date and age. Risk factors and comorbidities present within the year before index were examined. Exposure was defined as a HT prescription within 60 days before index. RESULTS: There were 20,359 VTE cases and 203,590 matched controls. A conditional logistic regression indicated that the greatest risks for VTE were from metastatic cancer (odds ratio [OR], 13.66; 95% CI, 12.64-14.75), hospitalization/surgery (OR, 8.51; 95% CI, 8.09-8.96), trauma (OR, 3.52; 95% CI, 3.32-3.73), comorbidity burden (OR, 3.51; 95% CI, 3.34-3.69), history of hypercoagulable condition (OR, 3.10; 95% CI, 2.87-3.36), and varicose veins (OR, 2.87; 95% CI, 2.56-3.22). Regarding hormone exposure, we observed ORs of 1.51 (95% CI, 1.43-1.60) for any recent hormone exposure; 1.13 (95% CI, 1.04-1.23; number needed to harm, 4,274) for unopposed estrogen menopausal HT; 1.23 (95% CI, 1.10-1.38; number needed to harm, 2,440) for combined menopausal HT; and 5.22 (95% CI, 4.67-5.84) for combined hormonal contraceptives compared with no recent HT exposure. CONCLUSIONS: Hormone therapy exposure did not appear to adversely influence other risk factors, and exposure generally played a minor role in VTE risk. Contraceptives, however, were a strong risk factor.

Factors Associated with COVID-19 Vaccine Uptake Among High School Students in a Large, Diverse Metropolitan Area.

BACKGROUND: Because previous studies on adolescent COVID-19 attitudes focused on intent to get vaccinated, this study examined attitudinal factors and racial/ethnic differences associated with vaccine uptake. METHODS: In a cross-sectional survey of a metropolitan high school district, students were asked about their COVID-19 attitudes, information sources, and whether they had been vaccinated. Logistic regression predicted vaccination status and adjusted odds ratios (aOR) controlled for race/ethnicity. RESULTS: Being unvaccinated was associated with themes of distrust with concerns about vaccine newness (aOR: 0.10; 95% confidence intervals [CI]: 0.06-0.15), side effects (aOR: 0.22; 95% CI: 0.15-0.33), efficacy (aOR: 0.25; 95% CI: 0.17-0.38), distrust of vaccines (aOR: 0.16; 95% CI: 0.09-0.27), government oversight (aOR: 0.19; 95% CI: 0.13-0.30), and politicization (aOR: 0.60; 95% CI: 0.41-0.88). Vaccine uptake was influenced by official information sources, school closures, and vaccine availability. The majority of vaccinated and unvaccinated students trusted primary care professionals as a source for COVID-19 information, but their influence varied across race/ethnic groups. CONCLUSIONS: Trust and distrust were the main themes of vaccinated and unvaccinated students, respectively. Incorporating trusted information sources (primary care professionals) in information dissemination efforts may improve vaccine uptake.

Hormone exposure and venous thromboembolism in commercially insured women aged 50 to 64 years.

Background: Menopausal hormone therapy (MHT) can elevate venous thromboembolism (VTE) risk, but less is known about formulations and routes of exposures. Objective: To estimate hormone-associated VTE risk by route and formulation in exposed and unexposed women aged 50 to 64 years in the US. Methods: In a nested case-control study of US commercially insured women aged 50 to 64 years (2007-2019), cases were defined as incident VTE diagnoses and matched to 10 controls by date of VTE and age, excluding prior VTE, inferior vena cava filter placement, or anticoagulants. Filled prescriptions in the prior year defined hormone exposures. International Classification of Diseases and Current Procedural Terminology codes identified risk factors and comorbidities. Results: Odds ratios (ORs) were estimated with conditional logistic regression controlling for differences between cases (n = 20,359) and controls (n = 203,590) in comorbidities and VTE risk factors. For exposures within 60 days, oral MHT risk was almost twice as high as transdermal MHT (OR = 1.92; 95% CI, 1.43-2.60); transdermal MHT did not elevate risk compared with no exposure (unopposed OR = 0.70; 95% CI, 0.59-0.83; combined OR = 0.73; 95% CI, 0.56-0.96). Risk was highest for MHT combinations with ethinyl estradiol, followed by conjugated equine estrogen (CEE) (ethinyl estradiol-CEE: OR = 1.55; 95% CI, 1.07-2.25), and lowest for estradiol (CEE-estradiol: OR = 1.33; 95% CI, 1.02-1.72). Combined hormonal contraceptives elevated risk 5 times higher than no exposure (OR = 5.22; 95% CI, 4.67-5.84) and 3 times higher than oral MHT (OR = 3.65; 95% CI, 3.09-4.31). Conclusion: The risk of VTE is much lower with MHT than combined hormone contraceptives and varies by hormone formulation and route of exposure. Transdermal MHT did not elevate risk. Oral MHT combinations with estradiol were lower risk than other forms of estrogen. Oral combined hormone contraceptives had much higher risk than oral combined hormonal MHT.

Statin Use and the Risk of Venous Thromboembolism in Women Taking Hormone Therapy.

Importance: Although hormone therapy (HT) in perimenopausal women is associated with increased risk for venous thromboembolism (VTE), it is unclear to what extent statins may mitigate this HT-associated risk. Objective: To estimate VTE risk in women aged 50 to 64 years taking HT with or without statins. Design, Setting, and Participants: This nested case-control study analyzed data from a commercially insured claims database in the US. Eligible participants included women aged 50 to 64 years with at least 1 year of continuous enrollment between 2008 and 2019. Data analysis occurred from January 2022 to August 2023. Exposure: Filled prescriptions for estrogens, progestogens, and statins were recorded in the 12 months prior to index. Recent HT was defined as any estrogen or progestogen exposure within 60 days before the index date. Current statin exposure was defined as 90 or more days of continuous exposure prior to and including the index date. Statin intensity was defined by the statin exposure 30 days prior to index. Main Outcomes and Measures: Cases were identified with VTE diagnoses (diagnostic codes) preceded by at least 12 months without VTE and followed within 30 days by anticoagulation, an inferior vena cava filter placement, or death. Controls were matched to cases (10:1) on date and age. Conditional logistic regression models estimated risk for HT and statin exposures with odds ratios (OR), adjusted for comorbidities. Conditional logistic regression models were used to estimate VTE risk for HT and statin exposures with odds ratios (ORs), adjusted for comorbidities. Intensity of statin therapy was measured as a subgroup analysis. Results: The total sample of 223 949 individuals (mean [SD] age, 57.5 [4.4] years) included 20 359 cases and 203 590 matched controls. Of the entire sample, 19 558 individuals (8.73%) had recent HT exposure and 36 238 individuals (16.18%) had current statin exposure. In adjusted models, individuals with any recent HT exposure had greater odds of VTE compared with those with no recent HT exposure (OR, 1.51; 95% CI, 1.43-1.60). Individuals receiving current statin therapy had lower odds of VTE compared with those with no current statin exposure (OR, 0.88; 95% CI, 0.84-0.93). When compared with those not recently taking HT or statins, the odds of VTE were greater for those taking HT without statins (OR, 1.53; 95% CI, 1.44-1.63) and for those taking HT with statins (OR, 1.25; 95% CI, 1.10-1.43), but were lower for those taking statins without HT (OR, 0.89; 95% CI, 0.85-0.94). Individuals taking HT with statin therapy had 18% lower odds of VTE than those taking HT without statins (OR, 0.82; 95% CI, 0.71-0.94) and there was greater risk reduction with higher intensity statins. Conclusions and Relevance: In this case-control study, statin therapy was associated with reduced risk of VTE in women taking HT, with greater risk reduction with high-intensity statins. These findings suggest that statins may reduce risk of VTE in women exposed to HT and that HT may not be contraindicated in women taking statins.

Can deliberately incomplete gene sample augmentation improve a phylogeny estimate for the advanced moths and butterflies (Hexapoda: Lepidoptera)?

This paper addresses the question of whether one can economically improve the robustness of a molecular phylogeny estimate by increasing gene sampling in only a subset of taxa, without having the analysis invalidated by artifacts arising from large blocks of missing data. Our case study stems from an ongoing effort to resolve poorly understood deeper relationships in the large clade Ditrysia ( > 150,000 species) of the insect order Lepidoptera (butterflies and moths). Seeking to remedy the overall weak support for deeper divergences in an initial study based on five nuclear genes (6.6 kb) in 123 exemplars, we nearly tripled the total gene sample (to 26 genes, 18.4 kb) but only in a third (41) of the taxa. The resulting partially augmented data matrix (45% intentionally missing data) consistently increased bootstrap support for groupings previously identified in the five-gene (nearly) complete matrix, while introducing no contradictory groupings of the kind that missing data have been predicted to produce. Our results add to growing evidence that data sets differing substantially in gene and taxon sampling can often be safely and profitably combined. The strongest overall support for nodes above the family level came from including all nucleotide changes, while partitioning sites into sets undergoing mostly nonsynonymous versus mostly synonymous change. In contrast, support for the deepest node for which any persuasive molecular evidence has yet emerged (78-85% bootstrap) was weak or nonexistent unless synonymous change was entirely excluded, a result plausibly attributed to compositional heterogeneity. This node (Gelechioidea + Apoditrysia), tentatively proposed by previous authors on the basis of four morphological synapomorphies, is the first major subset of ditrysian superfamilies to receive strong statistical support in any phylogenetic study. A "more-genes-only" data set (41 taxa×26 genes) also gave strong signal for a second deep grouping (Macrolepidoptera) that was obscured, but not strongly contradicted, in more taxon-rich analyses.

Vaginal Vitamin E for Treatment of Genitourinary Syndrome of Menopause: A Systematic Review of Randomized Controlled Trials.

Genitourinary syndrome of menopause significantly affects the quality of life in postmenopausal women with few evidence-based alternatives to vaginal estrogen for women with contraindications. This systematic review evaluates the evidence for vaginal vitamin E efficacy in reducing patient-reported genitourinary symptoms in healthy postmenopausal women compared to placebo or vaginal control therapy. This systematic review evaluated randomized controlled trials before October 2020 that assessed the efficacy of vitamin E vaginal suppositories in reducing genitourinary symptoms in postmenopausal women compared with a control group of healthy postmenopausal women. Outcomes included patient-perceived genitourinary symptoms. Of the 31 studies, four met the inclusion criteria. One 8-week trial (n = 42) found a significant reduction in vaginal symptoms in the 1 mg vitamin E group than the placebo group (difference in means, 5.3; 95% confidence interval [CI], 4.4 to 6.2). Another 8-week trial (n = 40) found 5 mg vaginal hyaluronic acid superior to 1 mg vitamin E (difference in means -0.50, 95% CI, -0.95 to -0.05). Two 12-week trials (n = 52 in each) found no difference between 0.5 g vaginal estrogen and 100 IU vaginal vitamin E in healthy postmenopausal women (difference in means: -0.19, 95% CI, -4.4 to 4.0, and -3.47, 95% CI, -13.8 to 6.8). Evidence from small, limited studies suggests that vaginal vitamin E may be effective in alleviating symptoms of genitourinary syndrome of menopause; however, additional high-quality studies are needed to determine efficacy, ideal dosing, and long-term safety.

Incidence of venous thrombotic events and events of special interest in a retrospective cohort of commercially insured US patients.

OBJECTIVE: To estimate the US incidence of thrombotic events and related rare diagnoses. DESIGN: Claims-based retrospective cohort study of incidence. SETTING: US commercial health insurance administrative claims database. PARTICIPANTS: Adults 25-64 years of age between 2015 and 2019 with a minimum of 12 consecutive thrombosis-free months of continuous enrolment beginning 2014 were selected. MAIN OUTCOMES: Age (10-year intervals) and sex stratum-specific incidence rates per 100 000 person-years were determined for venous thromboembolism (VTE), cerebral venous thrombosis (CVT) and other major venous thrombotic events, and events of special interest, including immune thrombocytopenic purpura (ITP), haemolytic-uremic syndrome (HUS) and heparin-induced thrombocytopenia (HIT). RESULTS: Of 13 249 229 enrollees (half female/male), incidence of venous thromboembolic events (deep vein thrombosis (DVT), pulmonary embolism (PE), CVT or other major venous thrombotic conditions) was 247.89 per 100 000 person-years (95% CI: 245.96 to 249.84). Incidence of VTE was 213.79 with ICD codes alone (95% CI: 211.99 to 215.59) and 129.34 (95% CI: 127.95 to 130.75) when also requiring a filled anticoagulation prescription or an inferior vena cava (IVC) filter. Incidence was 6.37 for CVT (95% CI: 6.07 to 6.69), 26.06 for ITP (95% CI: 25.44 to 26.78), 0.94 for HUS (95% CI: 0.82 to 1.06) and 4.82 for HIT (95% CI: 4.56 to 5.10). The co-occurrence of CVT with either ITP or HIT (diagnoses within 14 days of one another) was 0.090 (95% CI: 0.06 to 0.13). Incidence tended to increase with age and was higher for women under 55. Incidence for CVT, HUS and CVT with ITP or HIT was higher for women in all age groups. Incidence of PE and CVT increased significantly over the 5-year period, while DVT rates decreased. CONCLUSIONS: These results are the first US estimates for the incidence of thrombotic and rare events of interest in a large, commercially insured US population. Findings provide a critically important reference for determining excess morbidity associated with COVID-19 and more generally for vaccine pharmacovigilance.

Important-performance analysis to conceptualize goal priorities in community dwelling stroke survivors.

BACKGROUND: It is important for clinicians to have a better understanding of stroke survivor's goals. Important performance analysis (IPA) is a tool that could be utilized to identify goal priorities in rehabilitation. OBJECTIVES: To examine the utility of the IPA method to identify goal priorities in a diverse group of community dwelling stroke survivors. METHODS: Thirty-eight stroke survivors completed private structured interviews and were asked to rate their perceived importance and performance of 37 goal areas. Important-performance analysis (IPA) was utilized to determine goal priorities for the overall sample. Different IPA methods used to identify goal priorities were compared. Goal priorities were also compared by age (dichotomized as <65 and ≥65 years) and sex (male or female). RESULTS: The IPA method effectively separated the goals into the four quadrants, and distinguished which goals were a priority for the sample of stroke survivors. The five goals that were consistently identified as a focus area were: hand function, driving, balance, memory, and arm strength. Men rated mood control as more important than women (p = .046). The two goals rated as being more important for those older than 65 were home accessibility (p = .008) and skin health (p < .001). CONCLUSIONS: Stroke survivors continue to have goals related to their stroke recovery in the years after their stroke. Both current performance as well as perceived importance should be considered during goal discussions with stroke survivors. IPA can help identify goal priorities in this population.

Identifying sustainable lifestyle strategies for maintaining good glycemic control: a validation of qualitative findings.

INTRODUCTION: Diabetes self-care practices are less effective outside of controlled research settings, and almost half of patients do not achieve good glycemic control. Qualitative studies suggest some lifestyle strategies may be linked to good control, but those strategies have not been validated. This study provides population-based evidence that dietary strategies identified in qualitative studies are associated with glycemic control in US patients with diabetes. RESEARCH DESIGN AND METHODS: In a cross-sectional sample of the National Health and Nutrition Examination Survey (NHANES), qualitative self-management themes were matched to survey questions and used to predict good glycemic control (hemoglobin A1c <7.0% (53 mmol/mol)). Patients were limited to those 50 years of age and older with a diagnosis of diabetes for at least 1 year (N=465). RESULTS: Patients averaged 65 years of age with a body mass index of 32.56 kg/m2 and 42% reported no physical activity. In logistic regression models controlling for sociodemographic and medical history variables, self-monitoring of blood glucose, weight loss, and physical activity were not significantly associated with glycemic control. Instead, dietary practices such as consuming low-calorie foods (OR=4.05, 95% CI 1.64 to 10.01), eating less fat (OR=2.15, 95% CI 1.03 to 4.47), and reducing sodium (OR=1.94, 95% CI 1.18 to 3.17) were significantly associated with good glycemic control, as was diabetes education or consultation with a dietitian (OR=3.48, 95% CI 1.28 to 9.45). Non-adherence to medications (OR=0.27, 95% CI 0.11 to 0.68) and general dietary descriptions, such as following a 'diabetic diet' (OR=0.32, 95% CI 0.17 to 0.57) and 'changing eating habits for weight loss' (OR=0.34, 95% CI 0.15 to 0.77), were associated with poorer glycemic control. CONCLUSIONS: The NHANES validation of lifestyle management strategies suggests practices that may be sustainable. In a population that tends to be obese with low physical activity, successful self-care might emphasize specific dietary practices offering concrete touchpoints for patient communication and guidance. These strategies might help maintain glycemic control.

Intensity of statin therapy and muscle symptoms: a network meta-analysis of 153 000 patients.

OBJECTIVE: To estimate relative risk (RR) of statin-associated musculoskeletal symptoms by statin therapy intensity. SETTING: Network meta-analysis assessing multicentre randomised controlled trials (RCTs) across several countries. PARTICIPANTS: PubMed, Web of Science, Cochrane database and ClinicalTrials.gov were searched through January 2021 for doubled-blinded RCTs testing the effect of statin therapy on lipids with at least 1000 participants and 2 years of intended treatment. Two coders assessed articles for final inclusion, quality and outcomes. Treatment intensity was categorised according to American Heart Association definitions. OUTCOMES: Pairwise and network meta-analysis (NMA) estimated RR and risk difference with random effects modelling. Heterogeneity was evaluated with the I2 statistic. Outcomes included muscle symptoms (any, myalgia and attrition due to muscle symptoms), rhabdomyolysis and elevated creatine kinase (CK) (>10 × upper limit of normal). RESULTS: Of 2919 RCTs, 24 (n=152 461) met inclusion criteria. NMA results indicated risk was significantly greater for high compared with moderate intensity statin therapy for any muscle problem (RR=1.04, 95% CI 1.00 to 1.07; I2=0%), myalgia (RR=1.04, 95% CI 1.00 to 1.08; I2=0%, number needed to harm (NNH)=173), attrition due to muscle problems (RR=1.37, 95% CI 1.09 to 1.73, I2=0%, NNH=218) and elevated CK (RR=4.69, 95% CI 2.50 to 8.80; I2=7%, NNH=527). Risk also was significantly higher for high intensity compared with placebo for any muscle problem (RR=1.05, 95% CI 1.01 to 1.09, I2=0%), myalgia (RR=1.13, 95% CI 1.05 to 1.23; I2=0%, NNH=182), attrition due to muscle problems (RR=1.55, 95% CI 1.15 to 2.08, I2=0%, NNH=187) and elevated CK (RR=5.37, 95% CI 2.48 to 11.61; I2=7%, NNH=589). Due to inconsistency of results across sensitivity analyses, estimates were inconclusive for rhabdomyolysis and CK. There were no significant differences in risk between moderate intensity therapy and placebo for all outcomes. CONCLUSIONS: For approximately each 200 patients on high intensity statins, one additional patient may experience myalgia or discontinue therapy due to muscle problems compared with moderate intensity therapy. TRIAL REGISTRATION NUMBER: CRD42019112758.

Informed decision making changes test preferences for colorectal cancer screening in a diverse population.

PURPOSE: We wanted to better understand patient preferences and decision making about options for colorectal cancer screening. Consistency in patient preferences could improve patient-clinician communication about tests by simplifying and focusing discussions. METHODS: In a cross-sectional sample of primary care patients, cognitive ranking tasks were used to estimate patient preferences for fecal occult blood testing, flexible sigmoidoscopy, colonoscopy, and double-contrast barium enema before and after consideration of 13 test attributes, such as accuracy and scientific evidence. Patients also ranked the 13 test attributes and attribute descriptions in terms of importance. Friedman's nonparametric test was used to measure overall discrimination among items, and the average Pearson correlation coefficient (r) among participants was used to measure the degree of consistency in choices. RESULTS: Participants (n = 168) averaged 62.1 years of age, and 64.3% were of minority racial ethnicity. For test-specific attributes, preferences were for high test accuracy (r = 0.63, P < .001), amount of colon examined (r = 0.64, P < .001), strong scientific evidence for efficacy (r = 0.59, P < .001), minimum discomfort (r = 0.50, P < .001), and low risk of complications (r = 0.38, P < .001). When all 13 attributes were considered together, agreement dropped (r = 0.13, P < .001), but attributes considered most important for decision making were test accuracy, scientific evidence for efficacy, amount of colon examined, and need for sedation. Test preferences showed moderate agreement (r = 0.20, P < .001), and choices were fairly consistent before and after exposure to test-specific attributes (kappa = 0.17, P = .007). Initially the modal choice was fecal occult blood testing (59%); however, after exposure to test specific attributes, the modal choice was colonoscopy (54%). CONCLUSION: Participants were clear about the attributes that they prefer, but no single test has those attributes. Preferences were varied across participants and were not predictable; clinicians should discuss the full range of recommended tests for colorectal cancer with all patients.

Toward reconstructing the evolution of advanced moths and butterflies (Lepidoptera: Ditrysia): an initial molecular study.

BACKGROUND: In the mega-diverse insect order Lepidoptera (butterflies and moths; 165,000 described species), deeper relationships are little understood within the clade Ditrysia, to which 98% of the species belong. To begin addressing this problem, we tested the ability of five protein-coding nuclear genes (6.7 kb total), and character subsets therein, to resolve relationships among 123 species representing 27 (of 33) superfamilies and 55 (of 100) families of Ditrysia under maximum likelihood analysis. RESULTS: Our trees show broad concordance with previous morphological hypotheses of ditrysian phylogeny, although most relationships among superfamilies are weakly supported. There are also notable surprises, such as a consistently closer relationship of Pyraloidea than of butterflies to most Macrolepidoptera. Monophyly is significantly rejected by one or more character sets for the putative clades Macrolepidoptera as currently defined (P < 0.05) and Macrolepidoptera excluding Noctuoidea and Bombycoidea sensu lato (P < or = 0.005), and nearly so for the superfamily Drepanoidea as currently defined (P < 0.08). Superfamilies are typically recovered or nearly so, but usually without strong support. Relationships within superfamilies and families, however, are often robustly resolved. We provide some of the first strong molecular evidence on deeper splits within Pyraloidea, Tortricoidea, Geometroidea, Noctuoidea and others.Separate analyses of mostly synonymous versus non-synonymous character sets revealed notable differences (though not strong conflict), including a marked influence of compositional heterogeneity on apparent signal in the third codon position (nt3). As available model partitioning methods cannot correct for this variation, we assessed overall phylogeny resolution through separate examination of trees from each character set. Exploration of "tree space" with GARLI, using grid computing, showed that hundreds of searches are typically needed to find the best-feasible phylogeny estimate for these data. CONCLUSION: Our results (a) corroborate the broad outlines of the current working phylogenetic hypothesis for Ditrysia, (b) demonstrate that some prominent features of that hypothesis, including the position of the butterflies, need revision, and (c) resolve the majority of family and subfamily relationships within superfamilies as thus far sampled. Much further gene and taxon sampling will be needed, however, to strongly resolve individual deeper nodes.

Cross-cultural perspectives on physician and lay models of the common cold.

We compare physicians and laypeople within and across cultures, focusing on similarities and differences across samples, to determine whether cultural differences or lay-professional differences have a greater effect on explanatory models of the common cold. Data on explanatory models for the common cold were collected from physicians and laypeople in South Texas and Guadalajara, Mexico. Structured interview materials were developed on the basis of open-ended interviews with samples of lay informants at each locale. A structured questionnaire was used to collect information from each sample on causes, symptoms, and treatments for the common cold. Consensus analysis was used to estimate the cultural beliefs for each sample. Instead of systematic differences between samples based on nationality or level of professional training, all four samples largely shared a single-explanatory model of the common cold, with some differences on subthemes, such as the role of hot and cold forces in the etiology of the common cold. An evaluation of our findings indicates that, although there has been conjecture about whether cultural or lay-professional differences are of greater importance in understanding variation in explanatory models of disease and illness, systematic data collected on community and professional beliefs indicate that such differences may be a function of the specific illness. Further generalizations about lay-professional differences need to be based on detailed data for a variety of illnesses, to discern patterns that may be present. Finally, a systematic approach indicates that agreement across individual explanatory models is sufficient to allow for a community-level explanatory model of the common cold.

Patient-centered mobility outcome preferences according to individuals with stroke and caregivers: a qualitative analysis.

PURPOSE: To explore the mobility-related preferences among stroke survivors and caregivers following post-acute rehabilitation at inpatient or skilled nursing facilities. METHODS: In this cross-sectional study; semi-structured, qualitative interviews of stroke survivors (n = 24) and informal caregivers (n = 15) were conducted. The participants were recruited from the community. RESULTS: Comparative content analysis was used to identify themes by two independent coders. The survivors (68 years) and caregivers (58 years) mentioned mobility-related consequences including inability to walk, balance, drive, and transfer; and increased falls. The survivors (63%) and caregivers (73%) also mentioned the use of assistive devices. The common rehabilitation activities included: walking (62%); followed by standing and mobility; strength and balance; and wheelchair skills. Some stroke survivors were dissatisfied as their rehabilitation was not patient-centered. Frequently mentioned outcome preferences by survivors were ability to walk (88%), move, and balance. They also wanted to acquire assistive devices to move independently. Caregivers were concerned with the survivor's safety and wanted them to drive (53%), prevent falls, have home accommodations, and transfer independently. Caregivers (40%) also expressed the importance of receiving realistic information. CONCLUSIONS: This study suggests a need to consider the stroke survivors' and caregivers' mobility outcome preferences to improve the patient-centered rehabilitation care. Implications for Rehabilitation Stroke survivors and caregivers tend to differ in their outcome preferences. Caregivers expressed concern for transfers, driving, fall prevention, home modifications, and wished for realistic information. Incorporating stroke survivors and their families' perspectives during rehabilitation may enhance patient-centered outcomes.
