RESUMEN
BACKGROUND: Contemporary therapies improve breast cancer (BC) outcomes. Yet, many of these therapies have been increasingly linked with serious cardiotoxicity, including reports of profound hypertension. Yet, the incidence, predictors, and impacts of these events are largely unknown. METHODS: Leveraging two large U.S.-based registries, the National Inpatient Sample (NIS) and the Food and Drug Administration Adverse Event Reporting System (FAERS) databases, we assessed the incidence, factors, and outcomes of hypertensive events among BC patients from 2007 to 2015. Differences in baseline characteristics, hypertension-related discharges, and complications were examined over time. Further, we performed a disproportionality analysis using reporting-odds-ratios (ROR) to determine the association between individual BC drugs and hypertensive events. Utilizing an ROR cutoff of >1.0, we quantified associations by drug-class, and individual drugs with the likelihood of excess hypertension. RESULTS: Overall, there were 5,464,401 BC-admissions, of which 46,989 (0.8%) presented with hypertension. Hypertensive BC patients were older, and saw initially increased in-hospital mortality, which equilibrated over time. The mean incidence of hypertension-related admissions was 732 per 100,000 among BC patients, versus 96 per 100,000 among non-cancer patients (RR 7.71, p < 0.001). Moreover, in FAERS, those with hypertension versus other BC-treatment side-effects were more frequently hospitalized (40.1% vs. 36.7%, p < 0.001), and were most commonly associated with chemotherapy (45.9%). Outside of Eribulin (ROR 3.36; 95% CI 1.37-8.22), no specific drug was associated with a higher reporting of hypertension; however, collectively BC drugs were associated with a higher odds of hypertension (ROR 1.66; 95% CI 1.09-2.53). CONCLUSIONS: BC therapies are associated with a substantial increase in limiting hypertension.

PURPOSE: Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in cancer survivors, particularly after chest radiation therapy (RT). However, the extent to which CVD events are consistently reported in contemporary prospective trials is unknown. METHODS AND MATERIALS: From 10 high-impact RT, oncology, and medicine journals, we identified all latter phase trials from 2000 to 2019 enrolling patients with breast, lung, lymphoma, mesothelioma, or esophageal cancer wherein chest-RT was delivered. The primary outcome was the report of major adverse cardiac events (MACEs), defined as incident myocardial infarction, heart failure, coronary revascularization, arrhythmia, stroke, or CVD death across treatment arms. The secondary outcome was the report of any CVD event. Multivariable regression was used to identify factors associated with CVD reporting. Pooled annualized incidence rates of MACEs across RT trials were compared with contemporary population rates using relative risks (RRs). RESULTS: The 108 trials that met criteria enrolled 59,070 patients (mean age, 58.0 ± 10.2 years; 46.0% female), with 273,587 person-years of available follow-up. During a median follow-up of 48 months, 468 MACEs were reported (including 96 heart failures, 75 acute coronary syndrome, 1 revascularization, 94 arrhythmias, 28 strokes, and 20 CVD deaths; 307 occurred in the intervention arms vs 144 in the control arms; RR, 1.96; P < .001). Altogether, 50.0% of trials did not report MACEs, and 37.0% did not report any CVD. The overall weighted-trial incidence was 376 events per 100,000 person-years compared with 1408 events per 100,000 person-years in similar nontrial patients (RR, 0.27; P < .001). There were no RT factors associated with CVD reporting. CONCLUSION: In contemporary chest RT-based clinical trials, reported CVD rates were lower than expected population rates.
RESUMEN
BACKGROUND: Data describing antibiotic use in U.S. nursing homes remain limited. We report antibiotic use among skilled nursing facility residents from 29 U.S. nursing homes and assessed correlations between antibiotics prescribed to residents in skilled care and nursing home characteristics. DESIGN: Retrospective cohort study. SETTING: Twenty-nine U.S. nursing homes in the same healthcare corporation. PARTICIPANTS: Residents receiving skilled care in 2016. MEASUREMENTS: We used pharmacy invoice and nursing home census data to calculate the days of antibiotic therapy per 1,000 days of skilled care (1,000 DOSC), the rate of antibiotic starts per 1,000 DOSC, the length of antibiotic therapy, and the average antibiotic spectrum index. We also assessed correlations between antibiotic use and nursing home characteristics. RESULTS: Antibiotics accounted for an average of 9.6% (±0.6%) of systemic medications prescribed among residents receiving skilled care. On average, 26.8% (±2.9%) of antibiotics were intravenous. Fluoroquinolones were prescribed at the highest rates (19% across all facilities), followed by beta-lactam/beta-lactamase inhibitors (11%), first- and second-generation cephalosporins, sulfonamides, and oral tetracyclines (each at 9%). Both the proportion of residents using enrolled in Medicare and number of unique prescribers responsible for systemic prescriptions positively correlated with the rate of antibiotic starts. CONCLUSIONS: Our study demonstrates that pharmacy invoices represent a useful and preexisting source of data for assessing antibiotic prescriptions among individuals receiving skilled nursing care. The correlation between the number of unique prescribers and antibiotic starts suggests that prescribers are central to efforts to improve antibiotic use in nursing homes.

BACKGROUND: Inferior vena cava filter (IVCF) use is common after a venous thromboembolic event (VTE). Cancer is associated with higher rates of VTEs and is also seen in a significant proportion of patients requiring IVCF. As hospital readmissions remain a frequently scrutinized metric, we sought to evaluate the impact of cancer on hospital-readmission rates and in-hospital outcomes among patients with VTEs who received an IVCF. METHODS: Leveraging the 2013 to 2014 Nationwide Readmission Database, we identified adult patients presenting with a VTE in the United States and evaluated 30-day readmission rates and readmission in-hospital outcomes postindex-admission. Multivariable logistic regression was used to identify factors associated with readmission after an index-procedure, including traditional and nontraditional cardiovascular risk factors, as well as hospital-level characteristics. RESULTS: Among the 619 241 patients presenting with a VTE at index-admission, 11.2% of patients received IVCF on index-admission, of which 30.9% had cancer. The 30-day readmission rate amongst IVCF recipients was 15.8% (N = 10 927), and 19.9% amongst those with cancer compared to 13.9% in patients without cancer (P < .001). Moreover, cancer patients had longer lengths of stay in the hospital (4.5 ± 0.2 vs 4.0 ± 0.1 days; P = .02), higher cost of care ($10 900 ± 308 vs $9242 ± 206; P = .007), but no difference in mortality (8.3% vs 6.3%; P = .70) during readmission compared to noncancer patients. CONCLUSION: Readmission after IVCF placement is common. In patients readmitted after an IVCF implantation, those with cancer have longer hospital stays and higher costs of care. However, in-hospital mortality is similar to those without cancer.

BACKGROUND: Cardiovascular disease (CVD) has become an increasingly common limitation to effective anticancer therapy. Yet, whether CVD events were consistently reported in pivotal trials supporting contemporary anticancer drugs is unknown. OBJECTIVES: The authors sought to evaluate the incidence, consistency, and nature of CVD event reporting in cancer drug trials. METHODS: From the Drugs@FDA, clinicaltrials.gov, MEDLINE, and publicly available U.S. Food and Drug Administration (FDA) drug reviews, all reported CVD events across latter-phase (II and III) trials supporting FDA approval of anticancer drugs from 1998 to 2018 were evaluated. The primary outcome was the report of major adverse cardiovascular events (MACE), defined as incident myocardial infarction, stroke, heart failure, coronary revascularization, atrial fibrillation, or CVD death, irrespective of treatment arm. The secondary outcome was report of any CVD event. Pooled reported annualized incidence rates of MACE in those without baseline CVD were compared with reported large contemporary population rates using relative risks. Population risk differences for MACE were estimated. Differences in drug efficacy using pooled binary endpoint hazard ratios on the basis of the presence or absence of reported CVD were also assessed. RESULTS: Overall, there were 189 trials, evaluating 123 drugs, enrolling 97,365 participants (58.5 ± 5 years, 46.0% female, 72.5% on biologic, targeted, or immune-based therapies) with 148,138 person-years of follow-up. Over a median follow-up of 30 months, 1,148 incidents of MACE (375 heart failure, 253 myocardial infarction, 180 strokes, 65 atrial fibrillation, 29 revascularizations, and 246 CVD deaths; 792 in the intervention vs. 356 in the control arm; p < 0.01) were reported from the 62.4% of trials noting any CVD. The overall weighted-average incidence was 542 events per 100,000 person-years (716 per 100,000 in the intervention arm), compared with 1,408 among similar-aged non-cancer trial subjects (relative risk: 0.38; p < 0.01), translating into a risk difference of 866. There was no association between reporting CVD events and drug efficacy (hazard ratio: 0.68 vs. 0.67; p = 0.22). CONCLUSIONS: Among pivotal clinical trials linked to contemporary FDA-approved cancer drugs, reported CVD event rates trail expected population rates.

People living with the human immunodeficiency virus (HIV) should receive pneumococcal vaccinations as part of their routine health maintenance. Our goal was to create a "virtual clinic" to help increase rates of pneumococcal vaccination among people living with HIV without adding substantially to the workload of primary providers. We used administrative data from our Veterans Affairs (VA) medical center to identify a cohort of veterans living with HIV who were not current with either the 13-valent pneumococcal conjugate vaccine (PCV13), the 23-valent pneumococcal polysaccharide vaccine (PPSV23) or both. We enrolled these individuals (n = 99) into a virtual clinic, notified providers via the electronic medical record and mailed letters to the veterans recommending they receive a pneumococcal vaccine. We also wrote orders for the appropriate pneumococcal vaccine that expired after 90 days. Among the virtual clinic cohort, 38% (38/99) of patients received the recommended vaccine within 180 days. Concurrent with our intervention, the Veterans Health Administration deployed a system-wide pneumococcal vaccine clinical reminder that incorporated recent PCV13 recommendations. To discern any effect of the virtual clinic beyond that of the clinical reminder, we compared the rate of PCV13 vaccinations among all HIV-positive veterans at our institution to the equivalent population from 2 other VA medical centers in Ohio. With consideration of the VHA's system-wide clinical reminder, the proportion of HIV-positive patients who received PCV13 in the first 90 days following the virtual clinic intervention was greater at our facility compared to another Ohio VA medical center (P < 0.05). The virtual clinic improved the pneumococcal vaccine coverage among HIV-positive veterans. These outcomes suggest that even in conjunction with a system-wide clinical reminder, the virtual clinic strategy improves vaccination rates among a high-risk population.

BACKGROUND: To support the role of nurses as active proponents of antimicrobial stewardship in long-term care facilities, we developed an educational intervention consisting of a free online course comprised of 6 interactive modules. Here, we report the effect of the course on the knowledge, beliefs, and attitudes toward antimicrobial stewardship of nurses working in long-term care facilities. METHODS: We used a paired pre- and postcourse survey instrument to assess nurses' knowledge regarding the care of long-term care facility residents with infections and attitudes and beliefs regarding antimicrobial stewardship. RESULTS: There were 103 respondents, registered nurses or licensed practical nurses, who completed the pre- and postsurveys. Their mean knowledge scores improved from 75% (precourse) to 86% (postcourse, P <.001). After the course, nurses' agreement that their role influences whether residents receive antimicrobials increased significantly (P <.001). CONCLUSIONS: The online course improves nurses' knowledge regarding the care of long-term care facility residents with infections and improves their confidence to engage in antimicrobial stewardship activities. Empowering nurses to be antimicrobial stewards may help reduce unnecessary antibiotic use among institutionalized older adults.

OBJECTIVES: To identify features of community nursing home (NH) environments associated with lower rates of overall antibiotic use. DESIGN: This pilot study used an explanatory sequential design that incorporated comparative feedback about antibiotic use to inform a discussion about antimicrobial stewardship practices in community NHs. SETTING: NHs. PARTICIPANTS: Clinical leadership of five NHs. MEASUREMENTS: For the quantitative phase, the number of antibiotic prescriptions, length of therapy, and days of therapy/1,000 days of care were measured at six NHs. For the qualitative phase, semistructured interviews were conducted with healthcare workers in leadership positions at five community NHs. Transcripts from the recorded interviews were assessed using emergent thematic analysis. For the triangulation phase, themes from the semistructured interviews were evaluated in the context of each NH's antibiotic use. RESULTS: The number of antibiotic prescriptions ranged from 172 to 1,244, with 50% to 83% written for 7 days or fewer. All NHs reported a similar proportion of fluoroquinolone use (27-32% of days of therapy). Triangulation yielded six themes for which the environment at each facility ranged from less- to more-supportive antimicrobial stewardship: practice patterns, external influences, infection control, leadership, communication, and facility culture. All NHs reported pressure from well-intentioned family members to prescribe antibiotics. NHs with shorter lengths of therapy and lower overall antibiotic use were consonant with an environment more supportive of antimicrobial stewardship. CONCLUSION: These findings suggest several features of NHs that are supportive of antimicrobial stewardship: practice patterns grounded in established diagnostic criteria, proactive infection control and prevention, open communication and interconnectedness among staff.

Background. Little is known about the American public's perceptions or knowledge about antibiotic-resistant bacteria or antibiotic misuse. We hypothesized that although many people recognize antibiotic resistance as a problem, they may not understand the relationship between antibiotic consumption and selection of resistant bacteria. Methods. We developed and tested a survey asking respondents about their perceptions and knowledge regarding appropriate antibiotic use. Respondents were recruited with the Amazon Mechanical Turk crowdsourcing platform. The survey, carefully designed to assess a crowd-sourced population, asked respondents to explain "antibiotic resistance" in their own words. Subsequent questions were multiple choice. Results. Of 215 respondents, the vast majority agreed that inappropriate antibiotic use contributes to antibiotic resistance (92%), whereas a notable proportion (70%) responded neutrally or disagreed with the statement that antibiotic resistance is a problem. Over 40% of respondents indicated that antibiotics were the best choice to treat a fever or a runny nose and sore throat. Major themes from the free-text responses included that antibiotic resistance develops by bacteria, or by the infection, or the body (ie, an immune response). Minor themes included antibiotic overuse and antibiotic resistance caused by bacterial adaptation or an immune response. Conclusions. Our findings indicate that the public is aware that antibiotic misuse contributes to antibiotic resistance, but many do not consider it to be an important problem. The free-text responses suggest specific educational targets, including the difference between an immune response and bacterial adaptation, to increase awareness and understanding of antibiotic resistance.
RESUMEN
STUDY AIM: Stereophotogrammetric digital imaging enables rapid and accurate detailed 3D wound monitoring. This rich data source was used to develop a statistically validated model to provide personalized predictive healing information for chronic wounds. MATERIALS: 147 valid wound images were obtained from a sample of 13 category III/IV pressure ulcers from 10 individuals with spinal cord injury. METHODS: Statistical comparison of several models indicated the best fit for the clinical data was a personalized mixed-effects exponential model (pMEE), with initial wound size and time as predictors and observed wound size as the response variable. Random effects capture personalized differences. RESULTS: Other models are only valid when wound size constantly decreases. This is often not achieved for clinical wounds. Our model accommodates this reality. Two criteria to determine effective healing time outcomes are proposed: r-fold wound size reduction time, t(r-fold), is defined as the time when wound size reduces to 1/r of initial size. t(δ) is defined as the time when the rate of the wound healing/size change reduces to a predetermined threshold δ < 0. Healing rate differs from patient to patient. Model development and validation indicates that accurate monitoring of wound geometry can adaptively predict healing progression and that larger wounds heal more rapidly. Accuracy of the prediction curve in the current model improves with each additional evaluation. CONCLUSION: Routine assessment of wounds using detailed stereophotogrammetric imaging can provide personalized predictions of wound healing time. Application of a valid model will help the clinical team to determine wound management care pathways.

BACKGROUND: Ovarian cancer is the most lethal gynecologic disease in the United States, with more women dying from this cancer than all gynecological cancers combined. Ovarian cancer has been termed the "silent killer" because some patients do not show clear symptoms at an early stage. Currently, there is a lack of approved and effective early diagnostic tools for ovarian cancer. There is also an apparent severe knowledge gap of ovarian cancer in general and of its indicative symptoms among both public and many health professionals. These factors have significantly contributed to the late stage diagnosis of most ovarian cancer patients (63% are diagnosed at Stage III or above), where the 5-year survival rate is less than 30%. The paucity of knowledge concerning ovarian cancer in the United States is unknown. METHODS: The present investigation examined current public awareness and knowledge about ovarian cancer. The study implemented design strategies to develop an unbiased survey with quality control measures, including the modern application of multiple statistical analyses. The survey assessed a reasonable proxy of the US population by crowdsourcing participants through the online task marketplace Amazon Mechanical Turk, at a highly condensed rate of cost and time compared to traditional recruitment methods. CONCLUSION: Knowledge of ovarian cancer was compared to that of breast cancer using repeated measures, bias control and other quality control measures in the survey design. Analyses included multinomial logistic regression and categorical data analysis procedures such as correspondence analysis, among other statistics. We confirmed the relatively poor public knowledge of ovarian cancer among the US population. The simple, yet novel design should set an example for designing surveys to obtain quality data via Amazon Mechanical Turk with the associated analyses.

Ovarian cancer (OvCa) is the most lethal gynecologic disease in the United States, with an overall 5-year survival rate of 44.5%, about half of the 89.2% for all breast cancer patients. To identify factors that possibly contribute to the long-term survivorship of women with OvCa, we conducted a comprehensive online Ovarian Cancer Survivorship Survey from 2009 to 2013. This paper presents the design and implementation of our survey, introduces its resulting data source, the OVA-CRADLE™ (Clinical Research Analytics and Data Lifecycle Environment), and illustrates a sample application of the survey and data by an analysis of prediagnosis symptoms, using text mining and statistics. The OVA-CRADLE™ is an application of our patented Physio-MIMI technology, facilitating Web-based access, online query and exploration of data. The prediagnostic symptoms and association of early-stage OvCa diagnosis with endometriosis provide potentially important indicators for future studies in this field.
RESUMEN
The purpose of this study is to explore narcissistic and prosocial behaviors as reported by adolescents with and without substance dependency disorder (SDD). This study employs a quasi-experimental design using SDD adolescents compared with two normative samples of adolescents. In comparison to normative adolescents, adolescents with SDD were strongly distinguished by overt narcissistic behaviors and less monetary giving. Levels of narcissistic and prosocial behaviors among adolescents with SDD suggest a connection between self-centeredness and addiction. Results also suggest volunteerism as a potential option to counter narcissism in substance dependent adolescents.
