ABSTRACT

INTRODUCTION: The importance of exercise electrocardiogram (ECG) is still controversial in the prevention of cardiovascular events among sportsmen and sportswomen. The aim of this study was to assess the relevance of exercise ECG as a screening tool to prevent cardiovascular events when any cardiovascular disease (CVD) risk factors are present. METHODS: The study included leisure time asymptomatic sportsmen and sportswomen over age 35 evaluated from 2011 to 2016 at the University Hospital of Saint-Etienne (France). Major adverse cardiovascular events (MACE) and atrial fibrillation were collected at 3 years. RESULTS: Of the cohort of 2457 sportsmen and sportswomen (mean age 50.2 ± 9.4 years), 50 (2%) had a high-risk SCORE2. A total of 256 exercise ECGs (10%) were defined as positive, most of them due to silent myocardial ischemia (SMI) (n = 196; 8%). These 196 SMI cases led to 33 coronary angiograms (1%), which revealed 23 significant coronary stenoses requiring revascularization. In multivariate logistic regression analysis, having at least two CVD risk factors was independently associated with (1) positive exercise ECG (OR = 1.80 [95% CI: 1.29-2.52], p = 0.0006), with (2) suspected SMI (OR = 2.57 [95% CI: 1.10-6.02], p = 0.0304), with (3) confirmed SMI (OR = 8.20 [95% CI: 3.46-19.46], p < 0.0001) and with (4) cardiovascular events (MACE or atrial fibrillation) (OR = 6.95 [95% CI: 3.49-13.81], p < 0.0001) at 3 years (median). CONCLUSIONS: The study supports the European recommendations for the use of exercise ECG in evaluation of asymptomatic leisure time sportsmen over age 35. Having at least two CVD risk factors was the best predictor for presence of coronary artery stenosis that may increase the risk for adverse events.

ABSTRACT

BACKGROUND: Despite advances in human immunodeficiency virus (HIV) prevention methods, such as the advent of pre-exposure prophylaxis (PrEP), the number of people with newly acquired HIV remains high, particularly in at-risk groups. A prophylactic HIV vaccine could contribute to reduced disease prevalence and future transmission and address limitations of existing options, such as suboptimal long-term adherence to PrEPs. METHODS: This qualitative study aimed to capture perceptions towards and acceptance of prophylactic HIV vaccination in three adult populations in the United States: the general population, 'at-risk' individuals (e.g. men who have sex with men, transgender individuals, gender-nonconforming individuals, and individuals in a sexual relationship with a person living with HIV), and parents/caregivers of children aged 9-17 years. Interviews were conducted with 55 participants to explore key drivers and barriers to HIV vaccine uptake, and a conceptual model was developed. RESULTS: The sample was diverse; participants were 51% female, aged 20-57 years (mean 37 years), 33% with high school diploma as highest education level, and identified as White (42%), Black or African American (35%), of Hispanic, Latino, or Spanish origin (22%), or other races/ethnicities (8%) [groupings are not mutually exclusive]. Perceptions were influenced by individual, interpersonal, community, institutional, and structural factors. Overall, 98% of participants thought vaccination would be beneficial in preventing HIV. Key considerations/barriers included perceived susceptibility, i.e. whether participants felt there was a risk of contracting HIV (discussed by 90%); the clinical profile of the vaccine (e.g. the adverse effect profile [98%], and vaccine efficacy [85%], cost [73%] and administration schedule [88%]); and concerns around potential vaccine-induced seropositivity (VISP; 62%). Stigma was not found to be an important barrier, with a general view that vaccination status was personal. Participants in the 'at-risk' group were the most likely to accept an HIV vaccine (70%). Unique concerns in the subgroups included how a potential vaccine's clinical profile compared with PrEP, voiced by those receiving/considering PrEP, and considerations of children's views on the topic, voiced by parents/caregivers. CONCLUSIONS: Understanding these factors could help develop HIV vaccine research strategies and contribute toward public health messaging to support future HIV vaccination programs.

ABSTRACT

Current serologic tests for HIV screening and confirmation of infection present challenges to the adoption of HIV vaccines. The detection of vaccine-induced HIV-1 antibodies in the absence of HIV-1 infection, referred to as vaccine-induced seropositivity/seroreactivity, confounds the interpretation of test results, causing misclassification of HIV-1 status with potential affiliated stigmatization. For HIV vaccines to be widely adopted with high community confidence and uptake, tests are needed that are agnostic to the vaccination status of tested individuals (ie, positive only for true HIV-1 infection). Successful development and deployment of such tests will require HIV vaccine developers to work in concert with diagnostic developers. Such tests will need to match today's high-performance standards (accuracy, cost-effectiveness, simplicity) for use in vaccinated and unvaccinated populations, especially in low- and middle-income countries with high HIV burden. Herein, we discuss the challenges and strategies for developing modified serologic HIV tests for concurrent deployment with HIV vaccines.

ABSTRACT

BACKGROUND: Health literacy is a critical health determinant. To implement initiatives aiming at improving health literacy among children, adapted measurement tools are needed. OBJECTIVE: This study aimed to translate, adapt, and test the Health Literacy Survey Child Questionnaire-15 (HLS-Child-Q15) to assess health literacy among French-speaking 8- to 11-year-old pupils. METHODS: The HLS-Child-Q15 was translated and adapted to the French context to become the HLS-Child-Q15-FR. A cross-sectional survey was carried out using a written, self-reported questionnaire to assess the psychometric properties of the HLS-Child-Q15-FR. KEY RESULTS: Translation and adaptation of the HLS-Child-Q15 German-French translated versions were cross-referenced. Back-translation led to minor refinements. Qualitative pre-test among children led to simplifications in wording and structure. Validation of the HLS-Child-Q15-FR. Four trained interviewers collected data among 3,107 pupils in 74 elementary schools of the Auvergne-Rhône-Alpes region. HLS-Child-Q15-FR showed good reliability (alpha = 0.83). Exploratory factor analysis showed a two-factor model related to health care and primary prevention. Construct validity analyses suggested removing 3 items. External validity analyses indicated a significant and moderate relationship with perceived self-efficacy. CONCLUSION: This study aimed to address the issue of measuring health literacy among French-speaking 8- to 11-year-old pupils. The HLS-Child-Q15-FR showed a high internal consistency. Statistics suggested a two-dimensional thematic scale. These findings should be further investigated. [HLRP: Health Literacy Research and Practice. 2023;7(3):e144-e153.].

ABSTRACT

BACKGROUND: HIV poses significant challenges for vaccine development due to its high genetic mutation and recombination rates. Understanding the distribution of HIV subtypes (clades) across regions and populations is crucial. In this study, a systematic review of the past decade was conducted to characterize HIV-1/HIV-2 subtypes. METHODS: A comprehensive search was performed in PubMed, EMBASE, and CABI Global Health, yielding 454 studies from 91 countries. RESULTS: Globally, circulating recombinant forms (CRFs)/unique recombinant forms (URFs) accounted for 29% of HIV-1 strains, followed by subtype C (23%) and subtype A (17%). Among studies reporting subtype breakdowns in key populations, 62% of HIV infections among men who have sex with men (MSM) and 38% among people who inject drugs (PWIDs) were CRF/URFs. Latin America and the Caribbean exhibited a 25% increase in other CRFs (excluding CRF01_AE or CRF02_AG) prevalence between 2010-2015 and 2016-2021. CONCLUSIONS: This review underscores the global distribution of HIV subtypes, with an increasing prevalence of CRFs and a lower prevalence of subtype C. Data on HIV-2 were limited. Understanding subtype diversity is crucial for vaccine development, which need to elicit immune responses capable of targeting various subtypes. Further research is needed to enhance our knowledge and address the challenges posed by HIV subtype diversity.

ABSTRACT

Vaccine-induced seroreactivity/positivity (VISR/P) poses a significant and common challenge to HIV vaccine implementation, as up to 95% of vaccine recipients may be misclassified as having HIV infection by current HIV screening and confirmatory serological assays. We investigated whether internal HIV proteins could be used to overcome VISR and discovered a set of 4 antigens (gp41 endodomain, p31 integrase, p17 matrix protein, and Nef) that are recognized by antibodies produced in individuals with HIV infection but not in vaccinated individuals. When evaluated in a multiplex double-antigen bridging ELISA, this antigen combination had specificities of 98.1% prevaccination and 97.1% postvaccination, demonstrating the assay is minimally impacted by vaccine-induced antibodies. The sensitivity was 98.5%, further increasing to 99.7% when p24 antigen testing was included. Results were similar across HIV-1 clades. Although more technical advancements will be desired, this research provides the groundwork for the development of new fourth-generation HIV tests unaffected by VISR. IMPORTANCE While the detection of HIV infection is accomplished by several methods, the most common are serological tests that detect host antibodies produced in response to viral infection. However, the use of current serological tests may present a significant challenge to the adoption of an HIV vaccine in the future because the antibodies to HIV antigens detected in currently available tests also tend to be included as antigens in the HIV vaccines in development. The use of these serological tests may thus result in the misclassification of vaccinated HIV-negative individuals, which can have potential for significant harms for individuals and could prevent the widespread adoption and implementation of HIV vaccines. Our study aimed to identify and evaluate target antigens for inclusion in new serological tests that can be used to identify HIV infections without interference from vaccine-induced antibodies but also fit within existing platforms for HIV diagnostics.

ABSTRACT

INTRODUCTION: Decisions about prevention of and response to Ebola outbreaks require an understanding of the macroeconomic implications of these interventions. Prophylactic vaccines hold promise to mitigate the negative economic impacts of infectious disease outbreaks. The objective of this study was to evaluate the relationship between outbreak size and economic impact among countries with recorded Ebola outbreaks and to quantify the hypothetical benefits of prophylactic Ebola vaccination interventions in these outbreaks. METHODS: The synthetic control method was used to estimate the causal impacts of Ebola outbreaks on per capita gross domestic product (GDP) of five countries in sub-Saharan Africa that have previously experienced Ebola outbreaks between 2000 and 2016, where no vaccines were deployed. Using illustrative assumptions about vaccine coverage, efficacy, and protective immunity, the potential economic benefits of prophylactic Ebola vaccination were estimated using the number of cases in an outbreak as a key indicator. RESULTS: The impact of Ebola outbreaks on the macroeconomy of the selected countries led to a decline in GDP of up to 36%, which was greatest in the third year after the onset of each outbreak and increased exponentially with the size of outbreak (i.e., number of reported cases). Over three years, the aggregate loss estimated for Sierra Leone from its 2014-2016 outbreak is estimated at 16.1 billion International$. Prophylactic vaccination could have prevented up to 89% of an outbreak's negative impact on GDP, reducing the outbreak's impact to as little as 1.6% of GDP lost. CONCLUSION: This study supports the case that macroeconomic returns are associated with prophylactic Ebola vaccination. Our findings support recommendations for prophylactic Ebola vaccination as a core component of prevention and response measures for global health security.

ABSTRACT

Background: Although the health benefits of physical activity (PA) are recognized, prostate cancer patients do not follow PA recommendations. Barriers to PA, whether physical, environmental or organizational, are known. Furthermore, even when these barriers are overcome, this achievement is not systematically accompanied by lifestyle change. Many strategies have shown to be effective in increasing patient adherence to PA. This study aims to assess the feasibility and the viability of the Acti-Pair program which combines three strategies: peer support, a personalized and realistic PA project, and support from health and adapted physical activity professionals in a local context. Methods and analysis: We conducted a pilot study utilizing a mixed qualitative and quantitative methodology, employing feasibility and viability assessments. Quantitative assessments included recruitment, retention adherence rates, process and potential effectiveness (PA and motivation) indicators; while qualitative methods were used to evaluate the program's practicality, suitability and usefulness. Indicators of potential effectiveness were assessed before and after the intervention using a Wilcoxon test for matched data. Qualitative data were collected through semistructured interviews conducted by two researchers with various program stakeholders. The study lasted for 3 years. Results: Twenty-four patients were recruited over a 25-month period. Forty-two percent of patients completed the program 3 months after the beginning. We recruited 14 peers and trained nine peers over a 10-month period. The program was coordinated extensively by adapted PA professionals, while health professionals were involved in recruiting patients and peers. Self-reporting of moderate to vigorous PA was increased after the Acti-Pair program initiation [42.86 (30.76) at baseline to 53.29 (50.73)]. Intrinsic motivation significantly increased after participation in the Acti-Pair program [1.76 (1.32) before the intervention vs. 2.91 (1.13) after the intervention]. The key player to support the Acti-Pair program in the field has been the PA support system. The main challenge has been the difficulty of health professionals in promoting PA. Discussion: This pilot study has shown that the Acti-Pair program is feasible and viable. It will allow us to extend the peer support intervention to other contexts and assess the effectiveness of this intervention and its generalization.

ABSTRACT

Background: Oral anticoagulants generate a burden of care that can affect the patient's quality of life. The concept of treatment's burden measures the impact of medical care for the patient's quality of life. Various factors can exacerbate the burden. Several studies have assessed the satisfaction of patients treated with oral anticoagulants. Objective: This study has assessed the burden of patients treated with oral anticoagulants. Methods: An analytical cross-sectional study of patients recruited from pharmacies in the Loire. A questionnaire was carried out using the anti-clot treatment scale, assessing satisfaction, and the Zarit scale, assessing the burden on carers of demented patients. Results: Anticoagulants were a burden for 41% (n = 158) of the 389 responding patients. Anticoagulants' burden was higher when oral anticoagulant was responsible for side effects, anxiety or lifestyle changes. Conclusion: The patients could be satisfied with the benefit of the treatment, satisfied with its practical modalities, and describe modifications of lifestyle habits contributing to the burden of the treatment.


Introduction: Les anticoagulants oraux génèrent une charge de soins pouvant impacter la qualité de vie des patients. Le fardeau du traitement mesure l'impact de la prise en charge médicale sur la qualité de vie. Des facteurs divers peuvent aggraver le fardeau. Plusieurs études ont évalué la satisfaction des patients traités par anticoagulants oraux. Objectif: Cette étude a évalué le fardeau des patients traités par anticoagulants oraux. Méthode: Étude transversale analytique menée auprès de patients recrutés dans des pharmacies ligériennes. Un questionnaire a été réalisé à partir de l'échelle échelle anti-clot treatment scale évaluant la satisfaction et de l'échelle Zarit évaluant le fardeau des aidants de patients déments. Résultats: Les anticoagulants étaient un fardeau pour 41 % (n = 158) des 389 répondants. Le fardeau des anticoagulants était plus important lorsque l'AO était responsable d'effets secondaires, d'angoisse ou modifiait leurs habitudes de vie. Conclusion: Les patients interrogés pouvaient être convaincus du bénéfice du traitement, satisfaits de ses modalités pratiques, et décrire un fardeau du traitement.

ABSTRACT

BACKGROUND: Protection by preventive Ebola vaccines has been demonstrated in clinical trials, but a complete picture of real-world effectiveness is lacking. Our previous study modeling the impact of preventively vaccinating healthcare workers (HCW) alone or with a proportion of the general population (GP) estimated significant reductions in incidence and mortality. The model assumed 100% vaccine efficacy, which is unlikely in the real world. We enhanced this model to account for lower vaccine efficacy and to factor in reduced infectiousness and lower case fatality rate in vaccinated individuals with breakthrough infections. METHODS: The previous model was enhanced to still permit a risk, although lower, for vaccinated individuals to become infected. The enhanced model, calibrated with data from epidemics in Sierra Leone (SL) and North Kivu, Democratic Republic of the Congo, helped evaluate the impact of preventive Ebola vaccination in different scenarios based on different vaccine efficacy rates (90% and 30% reductions in infection risk in the base and conservative scenarios, respectively; additionally, both scenarios with 50% reductions in infectiousness and mortality) and vaccination coverage among HCWs (30%, 90%) and GP (0%, 5%, and 10%). RESULTS: The base scenario estimated that, depending upon the proportions of vaccinated HCWs and GP, 33-85% of cases and 34-87% of deaths during the 2014 SL epidemic and 42-89% of cases and 41-89% of deaths during the 2018 North Kivu epidemic would be averted versus no vaccination. Corresponding estimates for the conservative scenario were: 23-74% of cases and 23-77% of deaths averted during the SL epidemic and 31-80% of both cases and deaths averted during the North Kivu epidemic. CONCLUSIONS: Preventive vaccination targeting HCW alone or with GP may significantly reduce the size and mortality of an EVD outbreak, even with modest efficacy and coverage. Vaccines may also confer additional benefits through reduced infectiousness and mortality in breakthrough cases.

ABSTRACT

PURPOSE: The use of oral cancer drugs (OAD) has increased over the last two decades. The objective of this study was to measure the impact of a nurse-led telephone follow-up in the therapeutic management of patients treated with an OAD regarding toxicity, medication adherence and quality of life. METHODS: A randomized, multicenter, controlled trial was conducted. All consecutive over 18-year-old patients, treated in medical oncology, radiotherapy, or hematology departments, receiving OAD for any cancer were invited to participate to the study. A total of 183 patients treated for solid or hematological cancers with an OAD were randomly assigned to receive a nurse-led telephone follow-up or standard care for 24 weeks. Data were collected between 2015 and 2018. RESULTS: Nurse telephone follow-up did not improve the global score toxicity in the intervention group. However, telephone calls directed by trained nurses induced a significant decrease in number of patients with grade 3 adverse events throughout the follow-up [OR 0.45 (IC à 95%) (0.23, 0.9)](P = 0.03). There was no significant difference in quality of life and medication adherence between groups at any follow-up time point. CONCLUSIONS: In this first French real-life study, the advice provided by qualified nurses via phone calls improved the management of grade 3 toxicities but failed to demonstrate an improvement of all grades of toxicities. More prospective studies are needed to confirm the impact of telephone calls on the toxicities related to OAD. TRIAL REGISTRATION: Clinical trial registration is NCT02459483. Protection committee SUD-ESTI registration is 2015-A00527-42 on 13 April 2015. National Agency for the Safety of Medicines and Health Products registration is 150619-B on the 27 may 2015.

ABSTRACT

Heterologous vaccine regimens deliver antigens through different vaccine components or vector types at sequential time points. Clinical development shows promising results and several candidates may be progressing to licensure in the coming years. This study aimed at exploring future acceptance and uptake of such regimens (also called heterologous prime-boost) and to identify implementation-associated benefits and challenges. Survey tools were developed based on findings from a previous literature search shared with the study team, and exploratory interviews with global stakeholders. An online survey and key informant interviews in six countries were conducted with stakeholders at national and sub-national level, including policy-makers, regulators and implementers. The interview guide and the online survey covered: (a) awareness of, and knowledge about, heterologous vaccine regimens; (b) rating of regimen-associated perceived benefits and challenges; (c) anticipation of possible challenges in relation to four hypothetical introduction scenarios; (d) potential acceptance benefits and challenges at the policy, health facility and recipient level. Sixty-two interviews were conducted at national level. The online survey was completed by 50 participants. Across the four introduction scenarios, respondents considered the highest potential for the introduction of heterologous regimens for immunoprophylaxis was among adolescents/adults for diseases against which no vaccines are currently available. Most reservations were related to logistics, record keeping, and recipient compliance. Adding a new heterologous vaccine regimen to the routine immunization calendar for children was considered feasible if it could generate an increased and longer-term immune response. Introduction in preparation of or following a disease outbreak was considered less favourably, with respondents stressing the difficulty of logistics in emergency situations, and the potential lag in the onset of protection. The recent approval of the first heterologous vaccine regimen for the prevention of Ebola Virus Disease will soon bring new light to the topic.

ABSTRACT

Ebola epidemics constitute serious public health emergencies. Multiple vaccines are under development to prevent these epidemics and avoid the associated morbidity and mortality. Assessing the potential impact of these vaccines on morbidity and mortality of Ebola is essential for devising prevention strategies. A mean-field compartmental stochastic model was developed for this purpose and validated by simulating the 2014 Sierra Leone epidemic. We assessed the impacts of prophylactic vaccination of healthcare workers (HCW) both alone and in combination with the vaccination of the general population (entire susceptible population other than HCW). The model simulated 8,706 (95% confidence intervals [CI]: 478-21,942) cases and 3,575 (95%CI: 179-9,031) deaths in Sierra Leone, in line with WHO-reported statistics for the 2014 epidemic (8,704 cases and 3,587 deaths). Relative to this base case, the model then estimated that prophylactic vaccination of only 10% of HCW will avert 12% (95% CI: 6%-14%) of overall cases and deaths, while vaccination of 30% of HCW will avert 34% of overall cases (95% CI: 30%-64%) and deaths (95% CI: 30%-65%). Prophylactic vaccination of 1% and 5% of the general population in addition to vaccinating 30% of HCW was estimated to result in reduction in cases by 44% (95% CI: 39%-61%) and 72% (95% CI: 68%-84%) respectively, and deaths by 45% (95% CI: 40%-61%) and 74% (95% CI: 70%-85%) respectively. Prophylactic vaccination of even small proportions of HCW is estimated to significantly reduce incidence of Ebola and associated mortality. The effect is greatly enhanced by the additional vaccination even of small percentages of the general population. These findings could be used to inform the planning of prevention strategies.

ABSTRACT

OBJECTIVE: Little data about the management of drugs in terminally ill palliative care cancer patients is available. The present study aimed at describing the evolution of anticancer and non-anticancer treatments (NACTs) in cancer patients in palliative care units. The second objective was to identify factors leading to the medical decision to withdraw or not NACTs. METHODS: Data from 1,091 cancer patients hospitalized in palliative care units were prospectively collected in 2010-2011, through a multicenter, observational French cohort. RESULTS: The median overall survival after admittance in palliative care units was 15 days. Specific anticancer treatments were systematically stopped in the first 24 h in palliative care units, but for 4.5% of patients. Regarding NACTs, patients were heavily treated with strong opioids (74%), corticosteroids (51%), and antidepressants (21.8%) until death. Antiulcer agents (63.4%), antibiotics (25.7%), thrombosis prevention (21.8%), antidiabetics (7.6%), and transfusions (4%) were often also continuously prescribed. In multivariate analysis, ECOG PS 4 was an independent predictor of continuous prescription of morphine and an independent predictor of discontinuation of corticosteroids, proton-pump inhibitors, antidiabetics, and preventive anticoagulant therapy. Infection symptoms independently predicted continuous prescription of paracetamol. Paralysis and cancer palpable mass independently predicted corticosteroid withdrawal. Brain metastases independently predicted antiulcer withdrawal. Hemorrhage independently predicted preventive anticoagulant withdrawal. Availability to a venous access independently predicted paracetamol and antiulcer continuous prescriptions. Co-prescriptions independently predicted continuous prescriptions (antibiotics with antiulcer, antifungals with antibiotics) or withdrawal (preventive anticoagulant with antiplatelets and antifungals). CONCLUSIONS: NACT prescription remained commonplace in terminally ill palliative cancer patients, although their benefit is questionable.

ABSTRACT

OBJECTIVES: to prospectively evaluate the incidence and the clinical relevance on hematopoietic reconstitution of HHV-6 infection in autologous hematopoietic stem cell transplantation (ASCT) recipients. METHODS: HHV-6 DNA load was measured in whole blood specimens once during the 7 days before stem cell re-infusion and once a week after transplantation until hematopoietic recovery. Active HHV-6 infection was defined by 2 consecutive positive DNA loads. RESULTS: from July 2012 to February 2015, 196 adult patients undergoing ASCT were enrolled. Twenty-two (11.2%) patients developed active HHV-6 infection with a cumulative incidence of 19% at 40 days after transplantation. The onset of active HHV-6 infection occurred with a median of 13 days after stem cell re-infusion. HHV-6 infection was associated with an increased frequency of non-infectious complications (OR = 5.05; 95%CI 1.78-14.32; P < 0.001). Moreover, the severity of these non-infectious complications was higher in recipients exhibiting HHV-6 infection (OR = 4.62; 95%CI 1.32-16.2; p < 0.01). Delayed neutrophils 10 (IQR: 8-14) vs 8 (IQR: 6-11) days and platelets recoveries 15 (IQR: 11.8-18.5) vs 8 (IQR: 4-14) days were observed in patients with active HHV-6 infection compared to non-infected ones. CONCLUSIONS: in this study, 11.2% ASCT recipients presented active HHV-6 infection associated with significantly delayed hematologic reconstitution.

ABSTRACT

BACKGROUND: About one-third of patients with renal cell carcinoma (RCC) have detectable metastases at diagnosis. Among them, bone is the second most frequent metastatic site. Treatment of metastatic RCC mostly relies on anti-angiogenic (AA) therapies and, more recently, immunotherapy. Skeletal-related events (SREs) can be prevented with bone-targeted therapies such as denosumab (Dmab), which has demonstrated superiority when compared with zoledronic acid in solid tumors. However, there is limited available data on Dmab toxicity in combination with AA therapies in patients with kidney cancer. The objective of this study was to retrospectively analyze the toxicity profile (mainly osteonecrosis of the jaw [ONJ] and hypocalcemia) in patients with metastatic renal cell carcinoma (mRCC) treated with Dmab and AA therapy combination. PATIENTS AND METHODS: We conducted a multicenter retrospective study among centers from the French Groupe d'Etudes des Tumeurs Uro Genitales (GETUG). Patients with bone metastases who received concurrently or sequentially AA therapy and Dmab were included in this study. RESULTS: A total of 41 patients with mRCC were enrolled. Although no patient presented with severe hypocalcemia, ONJ occurred in 7 (17%) of 41 patients. Interestingly, all patients with ONJ received the Dmab and AA combination in the first line of treatment; among these patients, 3 patients had no risk factor other than the Dmab and AA combination. CONCLUSION: The incidence of ONJ was high in this real-life population of patients with mRCC treated with AA therapies combined with Dmab. This toxicity signal should warn physicians about this combination in the mRCC population.

ABSTRACT

INTRODUCTION: The announcement of cancer coupled with initiation of its treatment impacts patients' psychological and physical states as well as their lifestyles. The objective of this study was to identify and confirm the needs of patients starting off on anticancer chemotherapy treatment. METHODS: This study was based on a qualitative-quantitative mixed method. In 2009, a qualitative study was conducted at the Lucien Neuwirth Cancer Institut for cancer patients undergoing intravenous chemotherapy for the first time. Exploratory and semi-directed interviews were carried out by a sociologist. In 2014, a questionnaire was hetero-administered to 100 patients starting off on chemotherapy. RESULTS: Forty patients were interviewed in 2009. Ninety-seven patients answered the questionnaire in 2014. Food was a theme that was identified by a majority of patients in 2009 (13/40) and confirmed in 2014: 63% needed help in identifying favorable food and 67% in identifying those that had to be avoided. The other needs identified were those linked to better understanding of the treatment, of how it may affect the couple, its side effects, hygiene and beauty, and knowledge about other treatments. These needs were confirmed in 2014. New needs were elicited in 2014: activities and leisure (33%), psychological needs (32.6%), and family relations (29.9%). CONCLUSION: This study enabled us to identify, confirm, and enrich our knowledge of the needs of cancer patients starting off on intravenous chemotherapy. These results led to the modification of an existing patient education program for these patients, in order to fulfill their needs in an updated and tailored manner.

ABSTRACT

OBJECTIVE: To describe the current state of knowledge concerning the quality of reporting in phase II clinical trials in oncology and to describe the various methods published allowing this quality evaluation. METHODS: databases including MEDLINE and COCHRANE were searched. Reviews and meta-analyses analyzing the quality of the reporting of phase II trials in oncology were included. Descriptive analysis of the results was performed. RESULTS: Thirteen publications were retained. Only 2 publications adopted a systematic approach of evaluation of the quality of reporting by overall scores. The Key Methodological Score (KMS), proposed by Grellety et al., gathering 3 items, seemed adapted for such an evaluation. A score of 3/3 was found in 16.1% of the 156 phase II trials analysed by this score. The other reviews used a qualitative analysis to evaluate the reporting, via an analysis of a single criterion, generally the statistical plan of the study. This item was considered as having been correctly reported in less than 50% of the analysed articles. CONCLUSION: The quality of reporting in phase II trials in oncology is a field that has been investigated very little (13 publications). When it is studied, the estimated level of quality is not satisfactory, whatever the method employed. The use of an overall score of evaluation is a path which should be pursued, in order to get reliable results. It also seems necessary to propose strong recommendations, which would create a consensus for the methodology and the reporting of these studies.

ABSTRACT

BACKGROUND: The importance of exercise electrocardiogram (ECG) has been controversial in the prevention of cardiac events among sportsmen. The aim of this study was to determine the frequency of silent myocardial ischemia (SMI) from an exercise ECG and its relationship with induced coronary angiographic assessment and potentially preventable cardiac events. METHODS: This prospective cohort study included leisure time asymptomatic sportsmen over 35years old, referred from 2011 to 2014 in the Sports Medicine Unit of the University Hospital of Saint-Etienne. RESULTS: Of the cohort of 1500 sportsmen (1205 men; mean age 50.7±9.4years; physical activity level 32.8±26.8MET-h/week), 951 (63%) had at least one cardiovascular disease (CVD) risk factor. Family history, medical examination and standard resting 12-lead were collected. A total of 163 exercise ECGs (10.9%) were defined as positive, most of them due to SMI (n=129, 8.6%). SMI was an indication for coronary angiography in 23 cases, leading to 17 documented SMIs (1.1%), including 11 significant stenoses requiring revascularization. In multivariate logistic regression analysis, a high risk of CVD (OR=2.65 [CI 95%: 1.33-5.27], p=0.005) and an age >50years (OR=2.71 [CI 95%: 1.65-4.44], p<0.0001) were independently associated with confirmed SMI. CONCLUSIONS: The association of positive exercise ECG with significant coronary stenosis was stronger among sportsmen with CVD risk factors and older than 50years. Screening by exercise ECG can lower the risk of cardiac events in middle-aged and older sportsmen. One hundred tests would be enough to detect one silent myocardial ischemia at risk for cardiac event.

ABSTRACT

BACKGROUND: Phase II clinical trials are a cornerstone of the development in experimental treatments They work as a "filter" for phase III trials confirmation. Surprisingly the attrition ratio in Phase III trials in oncology is significantly higher than in any other medical specialty. This suggests phase II trials in oncology fail to achieve their goal. Objective The present study aims at estimating the quality of reporting in published oncology phase II clinical trials. DATA SOURCES: A literature review was conducted among all phase II and phase II/III clinical trials published during a 5-year period (2010-2015). STUDY ELIGIBILITY CRITERIA: All articles electronically published by three randomly-selected oncology journals with Impact-Factors>4 were included: Journal of Clinical Oncology, Annals of Oncology and British Journal of Cancer. INTERVENTION: Quality of reporting was assessed using the Key Methodological Score. RESULTS: 557 articles were included. 315 trials were single-arm studies (56.6%), 193 (34.6%) were randomized and 49 (8.8%) were non-randomized multiple-arm studies. The Methodological Score was equal to 0 (lowest level), 1, 2, 3 (highest level) respectively for 22 (3.9%), 119 (21.4%), 270 (48.5%) and 146 (26.2%) articles. The primary end point is almost systematically reported (90.5%), while sample size calculation is missing in 66% of the articles. 3 variables were independently associated with reporting of a high standard: presence of statistical design (p-value <0.001), multicenter trial (p-value = 0.012), per-protocol analysis (p-value <0.001). LIMITATIONS: Screening was mainly performed by a sole author. The Key Methodological Score was based on only 3 items, making grey zones difficult to translate. CONCLUSIONS & IMPLICATIONS OF KEY FINDINGS: This literature review highlights the existence of gaps concerning the quality of reporting. It therefore raised the question of the suitability of the methodology as well as the quality of these trials, reporting being incomplete in the corresponding articles.
