Key Points for Clinicians About the SEER Oral Cancer Survival Calculator.

Importance: In the setting of a new cancer diagnosis, the focus is usually on the cancer as the main threat to survival, but people may have other conditions that pose an equal or greater threat to their life than their cancer: a competing risk of death. This is especially true for patients who have cancer of the oral cavity, because prolonged exposure to alcohol and tobacco are risk factors for cancer in this location but also can result in medical conditions with the potential to shorten life expectancy, competing as a cause of death that may intervene in conjunction with or before the cancer. Observations: A calculator designed for public use has been released that allows patients age 20 to 86 years who have a newly diagnosed oral cancer to obtain estimates of their health status-adjusted age, life expectancy in the absence of the cancer, and probability of surviving, dying of the cancer, or dying of other causes within 1 to 10 years after diagnosis. The models in the calculator showed that patients with oral cavity cancer had a higher than average risk of death from other causes than the matched US population, and this risk increases by stage. Conclusions and Relevance: The Surveillance, Epidemiology and End Results Program Oral Cancer Survival Calculator supports a holistic approach to the life of the patient, and the risk of death of other causes is treated equally to consideration of the probability of death of the cancer. This tool may be usefully paired with the other available prognostic calculators for oral cancer and is an example of the possibilities now available with registry linkages to partially overlapping or independent data sets and statistical techniques that allow the use of 2 time scales in 1 analysis.

Translocation of bacterial LPS is associated with self-reported cognitive abilities in men living with HIV receiving antiretroviral therapy.

BACKGROUND: Gut damage allows translocation of bacterial lipopolysaccharide (LPS) and fungal ß-D-glucan (BDG) into the blood. This microbial translocation contributes to systemic inflammation and risk of non-AIDS comorbidities in people living with HIV, including those receiving antiretroviral therapy (ART). We assessed whether markers of gut damage and microbial translocation were associated with cognition in ART-treated PLWH. METHODS: Eighty ART-treated men living with HIV from the Positive Brain Health Now Canadian cohort were included. Brief cognitive ability measure (B-CAM) and 20-item patient deficit questionnaire (PDQ) were administered to all participants. Three groups were selected based on their B-CAM levels. We excluded participants who received proton pump inhibitors or antiacids in the past 3 months. Cannabis users were also excluded. Plasma levels of intestinal fatty acid binding protein (I-FABP), regenerating islet-derived protein 3 α (REG3α), and lipopolysaccharides (LPS = were quantified by ELISA, while 1-3-ß-D-glucan BDG) levels were assessed using the Fungitell assay. Univariable, multivariable, and splines analyses were performed. RESULTS: Plasma levels of I-FABP, REG3α, LPS and BDG were not different between groups of low, intermediate and high B-CAM levels. However, LPS and REG3α levels were higher in participants with PDQ higher than the median. Multivariable analyses showed that LPS association with PDQ, but not B-CAM, was independent of age and level of education. I-FABP, REG3α, and BDG levels were not associated with B-CAM nor PDQ levels in multivariable analyses. CONCLUSION: In this well characterized cohort of ART-treated men living with HIV, bacterial but not fungal translocation was associated with presence of cognitive difficulties. These results need replication in larger samples.

Sex as Biological Variable in Cardiac Mitochondrial Bioenergetic Responses to Acute Stress.

Cardiac dysfunction/damage following trauma, shock, sepsis, and ischemia impacts clinical outcomes. Acute inflammation and oxidative stress triggered by these injuries impair mitochondria, which are critical to maintaining cardiac function. Despite sex dimorphisms in consequences of these injuries, it is unclear whether mitochondrial bioenergetic responses to inflammation/oxidative stress are sex-dependent. We hypothesized that sex disparity in mitochondrial bioenergetics following TNFα or H2O2 exposure is responsible for reported sex differences in cardiac damage/dysfunction. Methods and Results: Cardiomyocytes isolated from age-matched adult male and female mice were subjected to 1 h TNFα or H2O2 challenge, followed by detection of mitochondrial respiration capacity using the Seahorse XF96 Cell Mito Stress Test. Mitochondrial membrane potential (ΔΨm) was analyzed using JC-1 in TNFα-challenged cardiomyocytes. We found that cardiomyocytes isolated from female mice displayed a better mitochondrial bioenergetic response to TNFα or H2O2 than those isolated from male mice did. TNFα decreased ΔΨm in cardiomyocytes isolated from males but not from females. 17ß-estradiol (E2) treatment improved mitochondrial metabolic function in cardiomyocytes from male mice subjected to TNFα or H2O2 treatment. Conclusions: Cardiomyocyte mitochondria from female mice were more resistant to acute stress than those from males. The female sex hormone E2 treatment protected cardiac mitochondria against acute inflammatory and oxidative stress.

The Role of Institution-Based Peer Support for Health Care Workers Emotionally Affected by Workplace Violence.

BACKGROUND: Academic health centers with peer support programs have identified a significant increase in requests linked to workplace violence (WPV) exposure. However, no known research has focused on supportive interventions for health care workers exposed to WPV. This study aimed to describe the expansion of two long-standing programs-University of Missouri Health Care's (MU Health Care) forYOU Team, The Johns Hopkins Hospital's (JHH) RISE (Resilence in Stressful Events) team-to WPV support, retrospectively summarize the related data, and share generalizable lessons. METHODS: A retrospective extraction and summary of the forYOU and RISE databases and the MU Health Care and JHH databases was performed tracking hospitalwide data on WPV. Two cases describe the experience of WPV victims. RESULTS: Between 2009 and 2019, forYOU documented 834 peer support interventions, 75 (9.0%) related to WPV (57 one-on-one encounters, 18 group support encounters). In 2018-2019 the forYOU Team experienced an increase in WPV encounters, with 43 of the team's activations (20%) related to WPV. Between 2011 and 2019, RISE recorded 367 peer support interventions, 80 (21.8%) of which were WPV-related (61 group support encounters, 19 one-on-one encounters). Forty-eight (60.0%) of these 80 encounters occurred in 2018-2019 alone, marking an increase in WPV encounters. Nurses were the most frequent callers of both programs. CONCLUSION: This study indicates the growing need for health care workers' support in the aftermath of WPV exposure in today's health care environment. Health care institutions should take a holistic approach to WPV, including timely access to interventional peer support programs.

A contemporary, nationwide analysis of surgery and radiotherapy treatment for prostate cancer.

OBJECTIVE: To characterize national clinical practice trends in the treatment of prostate cancer (PCa) in Australia. PATIENTS AND METHODS: Population-level data were extracted from existing Medicare Benefits Schedule data for radical prostatectomy (RP) and brachytherapy (2002-2016), as well as external beam radiotherapy (EBRT; 2012-2016). Treatment rates were calculated relative to whole and PCa populations among privately treated patients. Overall age-related and geographical trends were analysed. RESULTS: The use of RP and low-dose-rate (LDR) brachytherapy increased between 2002 and 2009, but subsequently decreased to 124 and 6.9 per 100 000 men, respectively, in 2016. More dramatic decreases were observed for men aged <65 years. From 2012, rates of RP (15% drop) and LDR brachytherapy (58% drop) decreased, while the use of EBRT remained steady, falling by 5% to 42 per 100 000 men in 2016. Overall treatment increased in the age group 75-84 years, with the rate of RP increasing by 108%. CONCLUSION: National claims data indicate there has been a reduction in PCa treatment since 2009, which is mostly attributable to a reduction in the treatment of younger patients and reduced use of brachytherapy. RP is most commonly used and its use is rising in men aged >65 years.

Diabetes Self-Management Education and Medical Nutrition Therapy: A Multisite Study Documenting the Efficacy of Registered Dietitian Nutritionist Interventions in the Management of Glycemic Control and Diabetic Dyslipidemia through Retrospective Chart Review.

BACKGROUND: Diabetes self-management education (DSME) and medical nutrition therapy (MNT) improve glycemic control and reduce risk of chronic comorbid disease. OBJECTIVE: Document outcomes for patients with type 2 diabetes (T2D) completing DSME and MNT through American Diabetes Association-recognized programs. DESIGN: Descriptive, retrospective chart review. PARTICIPANTS/SETTING: Four random samples of 100 records of patients with T2D completing DSME and MNT at each of four regional centers in Alabama, June 2013 to 2014, were chosen for review; after exclusions, 392 records were retained. OUTCOME MEASURES: Weight, body mass index (BMI), hemoglobin A1c (HbA1c), total cholesterol, low-density lipoprotein, high-density lipoproteins (HDL), triglycerides (TG), and TG-to-HDL ratio. ANALYSIS: Mixed-model analysis of variance was used to determine differences between continuous variables. McNemar test was used to assess frequency of patients reaching glycemic targets. Paired t tests were used to determine significance of lipid parameters. RESULTS: Significant reductions were observed at end of program and 1 year in weight (2.67±5.54 kg, P<0.001; 2.25±5.45 kg, P=0.001), BMI (0.93±1.91, P<0.001; 0.76±1.93, P=0.001), and HbA1c (1.82%±2.23%, P<0.001; 1.22%±2.15%, P<0.001). Patients managed by diet alone had a mean baseline HbA1c of 6.95% and exhibited a 0.8% reduction in HbA1c (P<0.001) at end of program. Those managed with diet plus drug therapy had a baseline HbA1c of 9% and exhibited a 2.09% reduction in HbA1c (P<0.001). Following DSME and MNT, 62% of patients reached glycemic targets (HcA1c≤7%), as compared with 32% at baseline (P<0.001). Significant reductions in TG were observed from baseline (162±74 mg/dL [4.19±1.91 mmol/L]) to follow-up (109±36 mg/dL [2.82±0.92 mmol/L]) (P<0.001). HDL increased from baseline (45±13 mg/dL [1.16±0.34 mmol/L]) to follow-up (48±11 mg/dL [1.24±0.28 mmol/L]) (P=0.05). The TG-to-HDL ratio improved from a baseline of 4.07±2.41 to 2.48±1.26 at follow-up (P<0.001). CONCLUSIONS: Reductions were observed in weight, BMI, HbA1c, TG, and TG-to-HDL ratio. Improved patient outcomes were achieved in the clinical setting and support universal coverage to increase patient access to DSME and MNT.

Comparison of fosfomycin against fluoroquinolones for transrectal prostate biopsy prophylaxis: an individual patient-data meta-analysis.

PURPOSE: To systematically review and meta-analyse available evidence comparing fosfomycin trometamol (FT) to fluoroquinolone (FQ) prophylaxis to prevent transrectal ultrasound-guided prostate biopsy (TRUSPB) related infectious complications. METHODS: Electronic databases were queried for studies comparing FT to FQ-based TRUSPB prophylaxis. Studies were assessed for comparable outcomes and methodological quality (ROBINS-I modification). The primary outcome measure was the relative odds of overall infectious complications following TRUSPB according to FT/FQ treatment, which was evaluated with meta-analysis. Safety and tolerability were also assessed. The relative odds of infections of different severity [Grade 1, bacteriuria and afebrile urinary tract infection (UTI); Grade 2, bacteraemia, febrile UTI, and urosepsis] according to FT/FQ treatment were also estimated. RESULTS: Five studies, being three prospective randomised trials and two retrospective cohort studies, representing 3112 patients, were included. The relative odds of an infectious complication (OR 0.22, 95% CI 0.09-0.54) or of a more severe (Grade 2) infection (OR 0.13, 95% CI 0.07-0.26) were significantly lower in those receiving FT compared to FQ prophylaxis. A low incidence of medication-related side effects was observed. There were less observed infections due to FQ-resistant pathogens in those receiving FT prophylaxis. CONCLUSIONS: Patients who received FT prophylaxis were less likely than those who received FQ prophylaxis to develop infections overall, as well as severe and resistant infections after TRUSPB. Assessing the performance of FT in other geographic locations or in comparison to targeted prophylaxis based on risk assessment or rectal cultures is desired.

Diabetes Self-Management Education and Medical Nutrition Therapy Improve Patient Outcomes: A Pilot Study Documenting the Efficacy of Registered Dietitian Nutritionist Interventions through Retrospective Chart Review.

BACKGROUND: Diabetes self-management education (DSME) and medical nutrition therapy (MNT) improve patient outcomes; poor reimbursement limits access to care. OBJECTIVE: Our aim was to develop methodology for tracking patient outcomes subsequent to registered dietitian nutritionist interventions, document outcomes for patients with type 2 diabetes attending an American Diabetes Association-recognized program, and obtain outcome data to support reimbursement and public policy initiatives to improve patient access to DSME and MNT. DESIGN: Retrospective chart review. PARTICIPANTS/SETTING: A random sample of 100 charts was chosen from the electronic medical records of patients with type 2 diabetes completing DSME and individualized MNT, June 2013 to 2014. OUTCOME MEASURES: Data were extracted on body mass index (calculated as kg/m2), weight, hemoglobin A1c, blood glucose, and lipids. STATISTICAL ANALYSIS: Mixed-model analysis of variance was used to determine differences between means for continuous variables; McNemar's tests and γ-statistic trend analysis were used to assess frequency of patients reaching glycemic targets. RESULTS: Significant weight loss was observed from baseline (94.3±21.1 kg) to end of program (91.7±21.2 kg [-1.6±3.9 kg]; P<0.001); weight loss in whites (-5.0±8.4 kg; P<0.001) exceeded that of African Americans (-0.8±9.0 kg; P>0.05). Significant hemoglobin A1c reduction was observed from baseline (8.74%±2.30%) to end of program (6.82%±1.37% [-1.92%±2.25%]; P<0.001) and retained at 1 year (6.90%±1.16%; P<0.001). Comparatively, 72% of patients reached hemoglobin A1c targets (≤7.0%) vs 27% at baseline (P=0.008). When stratified by diet alone and diet plus drug therapy, patients exhibited a 1.08%±1.20% (P<0.001) and 2.36%±2.53% (P<0.001) reduction in hemoglobin A1c, respectively. Triglycerides decreased from baseline 181.6±75.5 mg/dL (2.0±0.9 mmol/L) to 115.8±48.1 mg/dL (1.3±0.5mmol/L) (P=0.023). High-density lipoprotein increased from 41.4±12.4 mg/dL (1.1±0.3 mmol/L) to 47.3±12.4 mg/dL (1.2±0.3 mmol/L) (P=0.007). CONCLUSIONS: Retrospective chart review provides an operational model for abstracting existing patient outcome data subsequent to registered dietitian nutritionist interventions. In support of universal reimbursement and patient access to DSME with supplemental individualized MNT, reductions were observed in key outcome measures weight, body mass index, hemoglobin A1c, and triglycerides.

Carotenoids, vitamin A and risk of adenomatous polyp recurrence in the polyp prevention trial.

One trial reported beta-carotene supplementation was protective of adenomatous polyp recurrence in nonsmokers. We now examine the relation of serum and dietary carotenoids and vitamin A to adenomatous polyp recurrence in a subcohort of 834 participants in a low fat, high fiber, high fruit and vegetable dietary intervention, the Polyp Prevention Trial. Multivariate odds ratio (OR) and 95% confidence intervals (CI) of polyp recurrence were obtained using baseline or the average (first 3 years of the trial) carotenoid and vitamin A values after adjustment for covariates. Compared to the lowest quartile of baseline alpha-carotene concentrations, the OR of multiple polyp recurrence for the highest quartile was 0.55 (95% CI = 0.30-0.99) and the OR of right-sided recurrence was 0.60 (95% CI = 0.37-0.95). Baseline dietary intakes of alpha-carotene and vitamin A from food with/without supplements were inversely associated with any recurrence (p for linear trend = 0.03-alpha-carotene; p = 0.004 and p = 0.007 -intakes of vitamin A). Compared to the lowest quartile of averaged beta-carotene concentrations, the OR of multiple adenomas for the highest quartile was 0.40 (95% CI = 0.22-0.75) with an inverse trend (p = 0.02). The risk was inversely related to averaged: alpha-carotene concentrations and right-sided polyps; alpha-carotene intake and recurrence of any, multiple and right-sided polyps; beta-carotene intake and multiple adenoma recurrence; vitamin A from food (with supplements) and each adverse endpoint. Thus, alpha-carotene and vitamin A may protect against recurrence in nonsmokers and nondrinkers or be indicative of compliance or another healthy lifestyle factor that reduces risk.

Fruits, vegetables, and micronutrients in relation to breast cancer modified by menopause and hormone receptor status.

Whether fruit, vegetable, and antioxidant micronutrient consumption is associated with a reduction in breast cancer incidence remains unresolved. To address this issue, we analyzed data from a large population-based case-control study, with consideration given to whether the associations varied with menopausal status or with clinical characteristics of the cases' disease. Study participants completed a modified Block food frequency questionnaire, which included assessment of the frequency and portion sizes of 13 fruits and fruit juices and 16 vegetables and the use of multiple and single vitamin supplements. Statistical analyses were done on 1,463 cases and 1,500 controls. Among postmenopausal women, reduced odds ratios [OR; 95% confidence intervals (95% CI)] were noted for the highest fifth, as compared with the lowest fifth, of intake of any vegetables [0.63 (0.46-0.86); P for trend < 0.01] and leafy vegetables [0.66 (0.50-0.86); P for trend = 0.03] after controlling for age and energy intake. Adjusted ORs (95% CIs) were also decreased for postmenopausal breast cancer in relation to high intake of carotenoids, alpha-carotene, beta-carotene, lutein, and particularly lycopene [0.66 (0.48-0.90); P for trend = 0.03]. Inverse associations for fruits and vegetables were stronger for postmenopausal women with estrogen receptor (ER)+ tumors (OR, 0.65; 95% CI, 0.51-0.82) than ER- tumors (OR, 0.92; 95% CI, 0.64-1.32), but results were less consistent for micronutrients. No similarly reduced associations were observed among premenopausal women. ORs did not appreciably differ by in situ or invasive breast cancer or by whether cases had begun chemotherapy. Our results support an inverse association for fruit and vegetable intake among postmenopausal but not premenopausal breast cancer, which may be more pronounced among women with ER+ tumors.

Ethnic differences in the nutrient intake adequacy of premenopausal US women: results from the Third National Health Examination Survey.

OBJECTIVE: To examine the adequacy of dietary intake of calcium; folate; and vitamins C, D, E, B-6, and B-12 in premenopausal US women of differing ethnicity. DESIGN: Analyses of single and duplicate 24-hour recalls were conducted to determine dietary intake during the Third National Health and Nutrition Examination Survey. SUBJECTS: Three thousand five hundred eighty-five randomly selected women aged 20 to 50 years from across the United States who were not pregnant or lactating were examined between 1988 and 1994. STATISTICAL ANALYSES: Usual nutrient intake distributions were estimated using the Iowa State University method for adjustment of the distribution. The Estimated Average Requirement cut-point method was used to determine the proportion of women with inadequate intake for each nutrient in each ethnic group. RESULTS: More than 75% of women irrespective of ethnic group had usual intakes of calcium lower than the new Adequate Intake. More than 90% of the women had inadequate intakes of folate and vitamin E from food sources alone. More than half of smokers had inadequate intakes of vitamin C. Intakes of vitamins B-6 and B-12 were low in less than 10% of these women. APPLICATIONS/CONCLUSIONS: This article provides evidence that a high proportion of premenopausal US women are underconsuming a variety of nutrients. Dietary intakes alone are not currently adequate to meet the new recommended intakes. Nutritional supplement use is widespread and effective, but does not eliminate the concerns for at-risk populations. Awareness of the general inadequacies in intakes of vitamin E and folic acid at large, and in many women vitamin C as well, can help direct individual dietary recommendations and place the emphasis in group counseling on nutrients that are of widespread concern. In addition, foods rich in vitamins B-6 and of general nutritional benefit should be emphasized among African American women in the United States as a substantial proportion of this group is still showing inadequate intakes from foods.

An investigation of patient satisfaction following discharge after total hip replacement surgery.

PURPOSE: To investigate patient expectations of and satisfaction with in-hospital discharge planning after total hip-joint replacement surgery in early and late discharge patient groups. DESIGN: A qualitative study describing patients' experience of discharge planning. SAMPLE: Thirty-three consecutive patients requiring primary total hip-joint replacement from two metropolitan hospitals. METHODS: Participants completed in-depth, semistructured interviews on the day of discharge from the hospital and again 4 to 8 weeks later. Thematic analysis of the transcripts was made after comparing data from early and late discharge groups. FINDINGS: Attendance at preassessment clinic was facilitated acceptable satisfaction levels for patients in both early and late discharge groups. Although that written information provided was timely, restricted opportunity for dialogue with health professionals limited patient knowledge and understanding of recovery. CONCLUSIONS: Multidisciplinary teams in orthopaedic practice face the challenge of finding better ways to coordinate care and ensure people undergoing total hip-joint replacement therapy surgery have individualized care. A nurse mentor-coach could be one way to ensure patients' education needs in this area are met. IMPLICATIONS FOR NURSING RESEARCH: Future studies could investigate nurses' work in discharge planning and identify any influence that their holistic approach to care could bring to a collaborative discharge process.

Lycopene and the lung.

The human lung, due to the oxidative and ozone stress to which it is exposed, is particularly vulnerable to oxidative damage. Concentrations of dietary antioxidants in the lung epithelial lining and lining fluids may provide protection against oxidative damage. A randomized clinical trial was conducted to study the effects of supplemental, carotenoid-rich vegetable juice (V-8) on lung function macrophage levels of carotenoids and in moderating ozone-induced lung damage. Healthy young adults (n = 23) were exposed to 0.4 ppm ozone in a chamber for 2 hr after either 2 weeks of antioxidant supplementation (including one can of V-8 juice daily) or placebo. Mean lung concentrations of lycopene increased by 12%, and lung epithelial cell DNA damage as measured by the Comet Assay decreased 20% in supplemented subjects. No change in peripheral blood lymphocyte DNA damage was observed as evidenced by no change in mean comet area or length in supplemented or placebo subjects. We were not able to separate the effects of lycopene from other carotenoids or antioxidants administered in this study; however, lycopene is the predominant carotenoid in V-8 (it represents 88% of total carotenoids). A review of the epidemiologic literature providing evidence for the effect of lycopene (diet or serum) or tomatoes on the risk of lung cancer reveals 27 observational epidemiologic studies (18 case-control and nine cohort studies) reporting relative risk (RR) estimates. RR estimates for cohort studies ranged from 0.63 to 1.24 (mean RR = 0.93, SD = 0.16). Odds ratios (OR) for case-control studies ranged from 0.27 to 0.93 (mean OR = 0.61, SD = 0.16). Both plasma levels (RR = 1.01, OR = 0.37) and estimated intakes of lycopene from dietary sources (mean RR = 0.93, RR range = 0.80-1.05; mean OR = 0.67, OR range = 0.27-0.93) were examined. Seventeen studies, three of which were cohorts, reported their results at the level of tomato consumption rather than, or in addition to, lycopene consumption (mean RR = 0.89, RR range = 0.63-1.24; mean OR = 0.61, OR range = 0.37-0.80). The published epidemiologic literature shows an interaction between study design and the relationship between lycopene and/ or tomatoes and risk of lung cancer. Overall, cohort studies did not show an association, whereas case-control studies showed a decreased risk with greater consumption of lycopene and tomatoes. Although lycopene can be found in the human lung, and there is evidence, albeit weak, for a protective association with lung cancer, its biologic role remains to be elucidated.
