RESUMEN
Vitamin and mineral supplements are commonly used in diets for zoologic and companion animals. Because specific nutrient requirements are often unknown, informed decisions are based on literature for related species. Over 18 mon beginning in November 2017, an entire population of spot-tailed earless lizards (Holbrookia lacerata and Holbrookia subcaudalis) died (N = 33). All but two lizards were submitted for histopathology (94%). All examined cases had mineralization in at least one tissue; 71% (22 of 31) had multisystemic mineral deposits consistent with metastatic mineralization. No underlying causes were detected histologically. The supplement used for dusting the food items fed five to six times per week was inadvertently switched for 2 to 4 mon, and the incorrect supplement was found to contain fourfold the intended vitamin D3 concentration. Thus, hypervitaminosis D was considered the most likely cause. Interestingly, eastern collared lizards (Crotaphytus collaris), also fed prey supplemented five to six times a week, and over 50 other insectivorous reptile and amphibian species possibly receiving the supplement one to seven times a week did not appear affected. During this time, only two other cases of metastatic mineralization were diagnosed in other herpetofauna at this institution. Prior to receiving the incorrect supplement, there were no cases of metastatic mineralization detected in the earless lizard population. These cases highlight species-specific sensitivities, and the deleterious effects of excessive or inappropriate supplementation. It is important to confirm product identification on arrival, regularly conduct chemical analysis of supplements, and educate keepers and owners about adverse effects of inappropriate supplementation.

OBJECTIVES: Routinely used performance status scales, assessing patients' suitability for cancer treatment, have limited ability to account for multimorbidity, frailty and cognition. The Clinical Frailty Scale (CFS) is a suggested alternative, but research detailing its use in oncology is limited. This study aims to evaluate if CFS is associated with prognosis and care needs on discharge in oncology inpatients. METHODS: We evaluated a large, single-centre cohort study in this research. CFS was recorded for adult inpatients at a Regional Cancer Centre. The associations between CFS, age, tumour type, discharge destination and care requirements and survival were evaluated. RESULTS AND CONCLUSIONS: A total of 676 patients were included in the study. Levels of frailty were high (Median CFS 6, 81.8% scored ≥5) and CFS correlated with performance status (R = 0.13: P = 0.047). Patients who were frail (CFS ≥ 5) were less likely to be discharged home (62.9%) compared with those who were not classed as frail (86.1%) (OR 3.6 [95%CI 2.1 to 6.3]: P < 0.001). Higher CFS was significantly associated with poorer prognosis in all ages. Solid organ malignancy (hazard ratio [HR] 2.60 [95%CI 2.05-3.32]) and CFS (HR 1.43 [95%CI 1.29-1.59]; P < 0.001) were independently associated with poorer survival. This study demonstrated that CFS may help predict prognosis in adult oncology inpatients of any age. This may aid informed shared decision-making in this setting. Future work should establish if routine CFS measurement can aid the appropriate prescription of systemic therapy and enable early conversations about discharge planning.

Incidence of bilateral risk-reducing mastectomies (RRMs) is increasing. The aim of this study was to compare satisfaction, aesthetic and oncological outcomes in women undergoing RRM with implant-based reconstruction comparing nipple-sparing mastectomy (NSM) with skin-sparing mastectomy (SSM) (sacrificing the nipple +/− nipple reconstruction). Women who had undergone bilateral RRM between 1997 and 2016 were invited. Aesthetic outcome and nipple symmetry were evaluated using standardized anthropometric measurements. The oncological outcome was assessed at last documented follow up. Ninety-three women (186 breasts) participated, 60 (64.5%) had NSM, 33 (35.5%) SSM. Median time between surgery and participation was 98.4 months (IQR: 61.7−133.9). Of the women, 23/33 (69.7%) who had SSM underwent nipple reconstruction. Nipple projection was shorter in the reconstructed SSM group than the maintained NSM group (p < 0.001). There was no significant difference in overall symmetry (p = 0.670), satisfaction regarding nipple preservation (p = 0.257) or overall nipple satisfaction (p = 0.074). There were no diagnoses of breast cancer at a median follow up of 129 months (IQR: 65−160.6). Women who undergo nipple-sparing RRM maintain long-term nipple symmetry. Nipple projection was less maintained after nipple reconstruction. Although satisfaction with the nipples was higher in the NSM group, this did not reach statistical significance. No breast cancers developed after RRM with long-term follow up.
RESUMEN
PURPOSE: With early detection, breast conservation surgery with adequate surgical margins is the standard of care. The aim of this study was to evaluate the use of pre-operative duct endoscopy (DE) to target surgical resection, improve adequate margins and reduce re-excision operations. METHODS: Women with DCIS, stage I and II breast cancer suitable for breast conservation were randomized to DE-assisted wide local excision versus standard wide local excision (without DE). The primary endpoint was margin re-excision rates between the two groups. Secondary end points were: (i) volume differences of the surgical specimen; (ii) whether an extensive in situ component (EIC) influenced successful DE-guided resection. RESULTS: 78 women were randomized: 44 patients to no-DE and 34 patients to the DE group. The median age was 59 (49-65) and 56 (48-64) years in the two groups respectively with mean follow-up of 9.1 (4.2-11.1) years. There were 23 positive findings in 17 women in 30 successful DE procedures (17/30 = 56.7%). The surgical specimen volume, no-DE (17 [IQR 10-29] cm3) and DE 20 [IQR 12-28] cm3), did not differ, p = 0.377. The overall re-excision rate was 20/78 (26%), 9 (20%) and 11 (32% in the no-DE and DE groups, respectively, p = 0.233. CONCLUSIONS: This randomized clinical trial was limited by incomplete accrual. DE did not contribute to improved margin excision rates whether a target lesion was visualized or not. The presence of EIC did not improve efficacy of DE.

Background: Ovarian suppression in premenopausal women is known to reduce breast cancer risk. This study aimed to assess uptake and compliance with ovarian suppression using the luteinizing hormone releasing hormone (LHRH) analogue, goserelin, with add-back raloxifene, as a potential regimen for breast cancer prevention.Methods: Women at ≥30% lifetime risk breast cancer were approached and randomized to mammographic screening alone (C-Control) or screening in addition to monthly subcutaneous injections of 3.6 mg goserelin and continuous 60 mg raloxifene daily orally (T-Treated) for 2 years. The primary endpoint was therapy adherence. Secondary endpoints were toxicity/quality of life, change in bone density, and mammographic density.Results: A total of 75/950 (7.9%) women approached agreed to randomization. In the T-arm, 20 of 38 (52%) of women completed the 2-year period of study compared with the C-arm (27/37, 73.0%). Dropouts were related to toxicity but also the wish to have established risk-reducing procedures and proven chemoprevention. As relatively few women completed the study, data are limited, but those in the T-arm reported significant increases in toxicity and sexual problems, no change in anxiety, and less cancer worry. Lumbar spine bone density declined by 7.0% and visually assessed mammographic density by 4.7% over the 2-year treatment period.Conclusions: Uptake is somewhat lower than comparable studies with tamoxifen for prevention with higher dropout rates. Raloxifene may preserve bone density, but reduction in mammographic density reversed after treatment was completed.Impact: This study indicates that breast cancer risk reduction may be possible using LHRH agonists, but reducing toxicity and preventing bone changes would make this a more attractive option.

DNA methylation of tumor-suppressor genes occurs early in the molecular transformation of precursor events to breast cancer and is therefore of interest to screening in high-risk women. The aim of this study was to use tumor-suppressor genes that have previously been shown to be cancer predictive in tissue to evaluate the potential of DNA methylation assays in cells from duct lavage (DL) fluid. The frequency of target gene DNA methylation in tissue and DL of cancer and healthy control patients was assessed, and an association of DNA methylation between different duct systems in the same breast was explored. The cancer and control groups were identified in the outpatient clinic when surgical treatment was finalized. Tumor, adjacent tissue and bilateral DL samples for comparative DNA methylation studies were obtained during surgery from women with cancer. In the healthy control group, samples of tissue and DL were collected. Reverse transcriptase methylation-specific PCR was conducted on modified DNA purified from 42 cancer biopsies, 41 benign excision cavity biopsies (internal control), 29 benign biopsies (external control), and 119 DL specimens. A validated panel of cancer predictive genes was analyzed in the study bank of tissue and DL samples from cancer and healthy patients. The sensitivity of DNA methylation in DL samples compared with matched cancer tissue was highest for SCGB3A1 (90 %), CDH13 (91 %), and RARB (83 %). The genetic algorithm selected RASSF1A, RARB, and IGFBP7 as the optimum predictor set for detecting DNA methylation in cancer tissue. The optimum area under the ROC curve for DNA methylation in cancer compared with internal control healthy tissue from excision margins was 0.84. The area under the ROC curve for DNA methylation in cancer DL compared with contralateral benign DL was 0.76. DL cytology was not a helpful predictor of breast cancer. This study shows that relative patterns of tumor-suppressor gene hypermethylation in breast cancer tissue are significantly reflected in the DL from the cancer affected breast. Using DL, nonconcordant patterns of DNA methylation between different duct systems confer independent oncologic potential for distinct breast lobes. The approach of DNA methylation in DL may be substantiated by a larger trial of breast cancer biomarkers.

AIM: Nipple aspiration (NA) and duct lavage (DL) are modalities for obtaining breast duct fluid for biomarker analyses. The aim of this study was to assess the feasibility of obtaining serial NA and DL samples at consecutive patient visits for cytology assessment and the creation of a biobank. METHODS: Seventy eligible subjects were enroled at a single institution in the United Kingdom as part of an international multicentre study. Entry criteria were based on a 5-year Gail model risk of ≥2% or Claus score lifetime risk of ≥26%. Women underwent NA and DL in an outpatient clinic under local anaesthesia. RESULTS: The mean patient age was 48 (range 41-69)years. Sixty seven out of 70 women (96%) attended three consecutive 6 monthly visits and follow-up for 2 years. Three women withdrew due to intolerance of the DL procedure. 56/67 (83%) women produced NA fluid from at least one duct. 204/264 (77%) of ducts declared by NA were cannulated for DL. 170/204 (83%) produced DL samples with adequate cellularity. By the final visit 52/67 (78%) women produced DL, 28/52 (54%) of whom were premenopausal and 24/52 (46%) were postmenopausal. 50/52 women (96%) underwent repeated DL of 81 ducts on 3 consecutive visits. CONCLUSION: NA and DL are well tolerated for repeated assessment to obtain material for cytology and to create a biobank for future biomarker studies in women at high breast cancer risk.

PURPOSE: This study was designed to evaluate potential preventive effects of meditation or exercise on incidence, duration, and severity of acute respiratory infection (ARI) illness. METHODS: Community-recruited adults aged 50 years and older were randomized to 1 of 3 study groups: 8-week training in mindfulness meditation, matched 8-week training in moderate-intensity sustained exercise, or observational control. The primary outcome was area-under-the-curve global illness severity during a single cold and influenza season, using the Wisconsin Upper Respiratory Symptom Survey (WURSS-24) to assess severity. Health care visits and days of missed work were counted. Nasal wash collected during ARI illness was assayed for neutrophils, interleukin-8, and viral nucleic acid. RESULTS: Of 154 adults randomized into the study, 149 completed the trial (82% female, 94% white, mean age 59.3 ± 6.6 years). There were 27 ARI episodes and 257 days of ARI illness in the meditation group (n = 51), 26 episodes and 241 illness days in the exercise group (n = 47), and 40 episodes and 453 days in the control group (n = 51). Mean global severity was 144 for meditation, 248 for exercise, and 358 for control. Compared with control, global severity was significantly lower for meditation (P = .004). Both global severity and total days of illness (duration) trended toward being lower for the exercise group (P=.16 and P=.032, respectively), as did illness duration for the meditation group (P=.034). Adjusting for covariates using zero-inflated multivariate regression models gave similar results. There were 67 ARI-related days of-work missed in the control group, 32 in the exercise group (P = .041), and 16 in the meditation group (P <.001). Health care visits did not differ significantly. Viruses were identified in 54% of samples from meditation, 42% from exercise, and 54% from control groups. Neutrophil count and interleukin-8 levels were similar among intervention groups. CONCLUSIONS: Training in meditation or exercise may be effective in reducing ARI illness burden.

The concept of an intraductal approach to evaluate the breast microenvironment assumes direct access to the cancer-containing duct. Central duct access to the cancer-affected lobe is essential if cytology or cell markers are to be useful indicators of pre-malignant change. Access to the cancer-bearing lobe would be less important if field change effects of malignant change were predominantly supra-lobar. The aim of this study was to determine how often duct lavage fluid drains the breast cancer-affected segment. 58 patients undergoing mastectomy for breast cancer were recruited among which 47 had at least one fluid-yielding duct. Following duct lavage, fluid-yielding ducts were perfused ex vivo with Polyurethane Elastomer (PU4ii) resin. Specimens were sliced sagittally, and the extent of resin perfusion and anatomical relationship to the cancer-affected segment was recorded. Computed tomography (CT) scanning was performed on selected mastectomies before cut-up for a feasibility study of 3D duct reconstruction. The median number of fluid-yielding ducts cannulated per cancer-affected breast was 2 (range 1-4). 35/47 (74%) mastectomy specimens were successfully cannulated for resin perfusion. 29/35 (83%) showed tracing of the cancer-affected duct system, 6/35 resin perfusions traced duct systems unaffected by cancer and 12/35 perfusions extravasated. The proportion of sagittal breast slices perfused by resin was 13-68% (median 43%). Volume rendering CT showed it is feasible to produce a simulated image of the perfused ducts. Duct access to the cancer-containing segment is feasible in the majority of patients. Fluid-yielding ducts proportionately drain a significant volume of the breast. Large symptomatic cancers may cause obstruction with distal collapse. Further quantitative study of breast perfusion CT scans may be helpful for estimating the volume fraction of breast tissue perfused by fluid-yielding ducts. The intraductal approach is a valid concept for biomarker assessment of cancer-containing breast segments.

BACKGROUND: The long-term effects of smoking and smoking cessation on markers of cardiovascular disease (CVD) prognosis obtained during treadmill stress testing (TST) are unknown. The purpose of this study was to evaluate the long-term effects of smoking cessation and continued smoking on TST parameters that predict CVD risk. METHODS: In a prospective, double-blind, randomized, placebo-controlled trial of 5 smoking cessation pharmacotherapies, symptom-limited TST was performed to determine peak METs, rate-pressure product (RPP), heart rate (HR) increase, HR reserve, and 60-second HR recovery, before and 3 years after the target smoking cessation date. Relationships between TST parameters and treatments among successful abstainers and continuing smokers were evaluated using multivariable analyses. RESULTS: At baseline, the 600 current smokers (61% women) had a mean age of 43.4 (SD 11.5) years and smoked 20.7 (8.4) cigarettes per day. Their exercise capacity was 8.7 (2.3) METs, HR reserve was 86.6 (9.6)%, HR increase was 81.1 (20.9) beats/min, and HR recovery was 22.3 (11.3) beats. Cigarettes per day and pack-years were independently and inversely associated with baseline peak METs (P < .001), RPP (P < .01, pack-years only), HR increase (P < .05), and HR reserve (P < .01). After 3 years, 168 (28%) had quit smoking. Abstainers had greater improvements than continuing smokers (all P < .001) in RPP (2,055 mm Hg beats/min), HR increase (5.9 beats/min), and HR reserve (3.7%), even after statistical adjustment (all P < .001). CONCLUSIONS: Smokers with a higher smoking burden have lower exercise capacity, lower HR reserve, and a blunted exercise HR response. After 3 years, TST improvements suggestive of improved CVD prognosis were observed among successful abstainers.

BACKGROUND: We assessed ovarian cancer screening outcomes in women with a positive family history of ovarian cancer divided into a low-, moderate- or high-risk group for development of ovarian cancer. METHODS: 545 women with a positive family history of ovarian cancer referred to the Ovarian Screening Service at the Royal Marsden Hospital, London from January 2000- December 2008 were included. They were stratified into three risk-groups according to family history (high-, moderate- and low-risk) of developing ovarian cancer and offered annual serum CA 125 and transvaginal ultrasound screening. The high-risk group was offered genetic testing. RESULTS: The median age at entry was 44 years. The number of women in the high, moderate and low-risk groups was 397, 112, and 36, respectively. During 2266 women years of follow-up two ovarian cancer cases were found: one advanced stage at her fourth annual screening, and one early stage at prophylactic bilateral salpingo-oophorectomy (BSO). Prophylactic BSO was performed in 138 women (25.3%). Forty-three women had an abnormal CA125, resulting in 59 repeat tests. The re-call rate in the high, moderate and low-risk group was 14%, 3% and 6%. Equivocal transvaginal ultrasound results required 108 recalls in 71 women. The re-call rate in the high, moderate, and low-risk group was 25%, 6% and 17%. CONCLUSION: No early stage ovarian cancer was picked up at annual screening and a significant number of re-calls for repeat screening tests was identified.
RESUMEN
The purpose of this study was to identify attributes of community-based coalitions associated with member perceptions of greater impact. Based on Hackman's model of work group effectiveness, we hypothesized that member effort, knowledge and skill, and performance strategies would affect their perceptions of coalition impact. Findings from a lagged regression on a sample of forty-five youth-oriented coalitions indicated that two aspects of member effort were associated with subsequent perceived impact, as were performance strategies for both coalition governance and community interventions. There were no associations, however, between member knowledge and skill and perceived impact. These results suggest that leaders may improve perceived coalition impact by encouraging member participation in discussions and interventions and by developing effective strategies for both governance and implementation.
RESUMEN
The purpose of this study was to identify potential opportunities for improving member participation in community-based coalitions. We hypothesized that opportunities for influence and process competence would each foster higher levels of individual member participation. We tested these hypotheses in a sample of 818 members within 79 youth-oriented coalitions. Opportunities for influence were measured as members' perceptions of an inclusive board leadership style and members' reported committee roles. Coalition process competence was measured through member perceptions of strategic board directedness and meeting effectiveness. Members reported three types of participation within meetings as well as how much time they devoted to coalition business beyond meetings. Generalized linear models accommodated clustering of individuals within coalitions. Opportunities for influence were associated with individuals' participation both within and beyond meetings. Coalition process competence was not associated with participation. These results suggest that leadership inclusivity rather than process competence may best facilitate member participation.

BACKGROUND: Biodimensional devices may provide a superior breast form when an implant is considered for immediate breast reconstruction for breast cancer. The authors prospectively report patient perception of outcome using a permanent anatomical expander implant following a planned one-stage procedure. METHODS: The Quality of Life Questionnaire BR-23 was modified to measure body image perception, physical effects, cancer worry, and surgical choice. Responses were classified into four categories. A subset of patients completed the questionnaire 1 and 6 years after surgery. Data were compared using nonparametric analyses. RESULTS: One hundred ten patients were studied, with a mean follow-up of 63 months (range, 25 to 108 months); 46 patients had submuscular implant reconstruction and 64 had an implant-assisted latissimus dorsi flap. The mean patient age was 46 years (range, 20 to 76 years). There was no difference in patient perception of outcome between the two groups, although the latissimus dorsi group found it easier to fit into bras (p = 0.03, Mann-Whitney test). For patient perception of body image, the median score was within the most favorable category in four of six fields. Restricted arm movement and pain in the treated breast had resolved completely by 5 years after surgery. More than 80 percent of patients would choose the same surgical option if the cancer scenario presented itself again. CONCLUSIONS: A biodimensional permanent expander implant, when used appropriately, can achieve high levels of patient satisfaction. The authors' data provide long-term outcome measures with which to counsel patients about one-stage implant-assisted immediate breast reconstruction using an anatomical device.

OBJECTIVES: To conduct a pilot population-based study within a general practice catchment area to determine whether the incidence of breast cancer was increased in the Ashkenazi population. DESIGN: Population-based cohort study. SETTING: A single general practice catchment area in North London. PARTICIPANTS: 1947 women over the age of 16 who responded to a questionnaire about ethnicity and breast cancer. MAIN OUTCOME MEASURES: Incidence of breast cancer, ethnicity. RESULTS: This study showed a 1.5-fold (95% CI 0.93-2.39) increase in breast cancer risk in the Ashkenazim compared with the non-Ashkenazi white population. The increased incidence was for both premenopausal and postmenopausal breast cancer (expected incidence pre:post is 1:4 whereas in the Ashkenazim it was 1:1; 51 and 52% of cases respectively). This increase was not shown in the Sephardim. Asians had a reduction in incidence (OR = 0.44; 95% CI 0.10-1.89). Results were adjusted for other risk factors for breast cancer. CONCLUSION: This study showed a 1.5-fold increase in breast cancer rates in Ashkenazim compared with the non-Jewish white population when adjusted for age (i.e. corrections were made to allow comparison of age groups) and this is not observed in the Sephardic population. The proportion of premenopausal breast cancer was just over double that of the general population. This is the first general practice population-based study in the UK to address this issue and has implications for general practitioners who care for patients from the Ashkenazi community.
RESUMEN
Given both the importance and difficulty of promoting community-based public health coalitions, their capacity for sustainable action merits systematic examination. The current study addresses this need, focusing specifically on the relational dimension of capacity, that is, how relationships both among members and with external actors affect coalition-level activity. The context is a multimethod comparative case study of two rural cancer control coalitions. The authors began by using quantitative and qualitative data to characterize relational capacity in each coalition and then assessed the association between coalition-level relational capacity and level of subsequent interventions. The more active coalition had a more inclusive relational structure than did its less active counterpart but also placed less emphasis on personal friendships. The authors conclude that coalitions' relational structures are measurable and that this dimension of capacity may affect sustainable capacity for health promotion.

INTRODUCTION: Local coalitions combine the knowledge, expertise, and resources of many individuals and organizations to improve community health. This article describes data from 11 rural cancer coalitions in Pennsylvania and New York collected through a model-based data system. METHODS: The coalition data collection system was adapted from a conceptual model designed to monitor the activities and impact of cardiovascular disease coalitions. Community Coalition Action Theory was used during implementation and validation of the data system. Primary components of the data system were organizational capacity, process, and outcome/impact. RESULTS: From 2002 to 2004, the 11 coalitions conducted 1369 initiatives, including 1147 (83.8%) interventions and 222 (16.2%) development activities. Among interventions, 776 (56.7%) were outreach only, 158 (11.5%) education only, 117 (8.5%) outreach and education, and 96 (7.0%) screening. Differences in the distribution of initiatives by coalition, cancer site, and target audience were statistically significant (P < .05). The majority of interventions focused on colorectal (37.0%) and breast (32.9%) cancer. Target groups included women (71.3%), rural residents (32.6%), survivors (21.8%), and low-income (21.8%) individuals. Although not statistically significant, an observed 3-year trend was shown for decreased outreach interventions and increased education and screening interventions. In total, 1951 of 3981 individuals who were offered a cancer screening (49%) completed screening, and 15 sustainable community changes were documented. CONCLUSION: This study reports the initiatives and impact of 11 rural community cancer coalitions over a 3-year period. This study estimates the mix of development activities and community interventions, against which this coalition network and others may be compared.

INTRODUCTION: The incidence of colorectal cancer in portions of rural Appalachia is higher than in much of the United States. To reduce this disparity, cancer-control strategies could be adapted to and implemented in rural Appalachian communities. The objectives of this pilot study were to develop and test community-based participatory research methods to examine whether cancer coalitions in Appalachia could effectively disseminate print materials from a national media campaign intended to promote colorectal cancer awareness to their rural communities. METHODS: This pilot study used a two-arm intervention design with random selection of 450 community organizations from nine counties with cancer coalitions (the coalition arm) and 450 organizations from nine matched counties without a cancer coalition (the noncoalition arm) in northern Appalachia. The primary outcome measures were participation by and interest of community organizations in dissemination of materials from Screen for Life: National Colorectal Cancer Action Campaign, a national campaign to promote colorectal cancer education and screening. The data were collected with prestudy and poststudy surveys. RESULTS: One-hundred thirty (29%) organizations participated in the coalition arm, and 38 (8%) participated in the noncoalition arm (P < .001). Within the coalition arm, 86 of the 119 (66%) organizations that responded to the question about influence reported being influenced to participate by the local coalition. Initial interest in dissemination was high in each of the study arms but remained higher throughout the study in the coalition arm than the noncoalition arm. CONCLUSION: Community cancer coalitions can increase the local dissemination of material from a national media campaign in rural Appalachia. Continued development and study of methods for coalitions to translate and implement cancer-control strategies at a local level in Appalachia is warranted.
