In Vivo Confocal Microscopy in Avellino Corneal Dystrophy.

Corneal dystrophies are a group of rare genetic eye disorders characterized by the accumulation of abnormal material in different layers of the cornea, potentially leading to vision impairment. In vivo confocal microscopy (IVCM) is an emerging non-invasive imaging and diagnostic tool that helps study the ocular surface microstructure. This case report examines the clinical characteristics of Avellino corneal dystrophy in a young patient through the use of slit lamp examination, IVCM, and optical coherence tomography (OCT) in order to assess the effectiveness of these non-invasive tests as diagnostic tools.

Unraveling persistent dyspnea after mild COVID: insights from a case series on hyperventilation provocation tests.

Dyspnea is a common yet poorly understood symptom of long COVID, affecting many patients. This brief report examines the role of dysfunctional breathing in persistent dyspnea among patients with mild post-COVID-19 using hyperventilation provocation tests (HVPT). In this case series, six patients with unexplained dyspnea and normal cardiopulmonary function underwent HVPT. Despite normal exercise testing results, all patients exhibited delayed PETCO2 recovery, indicative of a hyperventilation pattern consistent with chronic hyperventilation syndrome, without typical symptomatic manifestations. These findings suggest underlying post-COVID respiratory dysregulation, emphasizing the importance of targeted diagnostic and therapeutic approaches for persistent respiratory symptoms in long COVID patients.

Current Approaches to Salvage Surgery for Head and Neck Cancer: A Comprehensive Review.

Salvage surgeries of head and neck cancer are often complicated and do not always show decent results. This type of procedure is tough on the patient, as many crucial organs can be affected. A long period of reeducation usually follows the surgery because of the need to rehabilitate functions such as speech or swallowing. In order to lighten the journey of the patients, it is important to develop new technologies and techniques to ease the surgery and limit its damages. This seems even more crucial since progress has been made in the past years, allowing more salvage therapy to take place. This article aims at showing the available tools and procedures for salvage surgeries, such as transoral robotic surgery, free-flap surgery, sentinel node mapping, and many others, that help the work of the medical team to operate or obtain a better understanding of the status of the cancer when taken in charge. Yet, the surgical procedure is not the only thing determining the outcome of the operation. The patient themself and their cancer history also play an important part in the care and must be acknowledged.

A randomized trial to evaluate the effects of a supervised exercise program on insomnia in patients with non-metastatic breast cancer undergoing chemotherapy: design of the FATSOMCAN study.

BACKGROUND: Up to 70% of breast cancer patients report symptoms of insomnia during and after treatment. Despite the ubiquity of insomnia symptoms, they are under-screened, under-diagnosed and poorly managed in breast cancer patients. Sleep medications treat symptoms but are ineffective to cure insomnia. Other approaches such as cognitive behavioral therapy for insomnia, relaxation through yoga and mindfulness are often not available for patients and are complex to implement. An aerobic exercise program could be a promising treatment and a feasible option for insomnia management in breast cancer patients, but few studies have investigated the effects of such a program on insomnia. METHODS: This multicenter, randomized clinical trial evaluate the effectiveness of a moderate to high intensity physical activity program (45 min, 3 times per week), lasting 12 weeks, in minimizing insomnia, sleep disturbances, anxiety/depression, fatigue, and pain, and in enhancing cardiorespiratory fitness. Patients with breast cancer be recruited from six hospitals in France and randomly allocated to either the "training" or the "control" group. Baseline assessments include questionnaires [Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index questionnaire (PSQI), Hospital Anxiety Depression Scale (HADS), Epworth Sleepiness Scale (ESS)], home polysomnography (PSG), and 7-day actigraphy coupled with completion of a sleep diary. Assessments are repeated at the end of training program and at six-month follow-up. DISCUSSION: This clinical trial will provide additional evidence regarding the effectiveness of physical exercise in minimizing insomnia during and after chemotherapy. If shown to be effective, exercise intervention programs will be welcome addition to the standard program of care offered to patients with breast cancer receiving chemotherapy. TRIAL REGISTRATION: National Clinical Trials Number (NCT04867096).

Real-Life Effectiveness of Benralizumab, Mepolizumab and Omalizumab in Severe Allergic Asthma Associated with Nasal Polyps.

Biological therapies are available for the treatment of the severe allergic asthma (SAA) with blood eosinophil count ≥ 0.3 × 109/L. Several of them also showed benefits on nasal polyps (NP), one of the most frequent comorbidities of the severe asthma, but comparative studies on their effectiveness in the association SAA-NP are currently lacking. The aim of this study is to compare the effectiveness of benralizumab, mepolizumab and omalizumab in patients with SAA-NP in real-life settings. A retrospective, observational, multicenter real-life study was realized including patients with SAA-NP treated by benralizumab, mepolizumab or omalizumab for 6 months. We analysed the nasal and respiratory symptoms, the number of asthma attacks and salbutamol use/week, acute sinusitis and severe exacerbation rates, the asthma control score, the lung function parameters, the NP endoscopic score, the sinus imaging and the blood eosinophil count 6 months before and after treatment. Seventy-two patients with SAA-NP were included: 16 treated by benralizumab, 21 by mepolizumab and 35 by omalizumab. After 6 months of treatment, almost all studied parameters were improved (except sinus imaging) with a greater effect of omalizumab on the nasal pruritus (p = 0.001) and more benefits of benralizumab on exacerbations rate, asthma attacks per week and lung function (all p < 0.05). Benralizumab and mepolizumab were more effective to improve the NP endoscopic score and the blood eosinophil count (both p < 0.001). All three biological therapies showed effectiveness by improving asthma and nasal outcomes in patients with SAA-NP. Several differences have been found that should be confirmed by larger comparative studies.

Cardiotoxicity is mitigated after a supervised exercise program in HER2-positive breast cancer undergoing adjuvant trastuzumab.

Background: Trastuzumab is used, alone or in conjunction with standard chemotherapy, to treat HER2-positive breast cancer (BC). Although it improves cancer outcomes, trastuzumab. can lead to cardiotoxicity. Physical exercise is a safe and effective supportive therapy in the management of side effects, but the cardioprotective effects of exercise are still unclear. Objectives: The primary aim of this study was to test whether trastuzumab-induced cardiotoxicity [left ventricular ejection fraction (LVEF) under 50%, or an absolute drop in LVEF of 10%] was reduced after a supervised exercise program of 3 months in patients with HER2-positive breast cancer. Secondary endpoints were to evaluate (i) cardiotoxicity rates using other criteria, (ii) cardiac parameters, (iii) cardiorespiratory fitness and (iv) whether a change in LVEF influences the cardiorespiratory fitness. Methods: 89 women were randomized to receive adjuvant trastuzumab in combination with a training program (training group: TG; n = 46) or trastuzumab alone (control group: CG; n = 43). The primary and secondary endpoints were evaluated at the end of the supervised exercise program of 3 months (T3). Results: After exercise program, 90.5 % of TG patients and 81.8% of CG patients did not exhibit cardiotoxicity. Furthermore, whatever the used criterion, percentage of patients without cardiotoxicity were greater in TG (97.6 and 100% respectively) than in CG (90.9 and 93.9% respectively). LVEF and GLS values remained stable in both groups without any difference between the groups. In contrast, at T3, peak VO2 (+2.6 mL.min-1.kg-1; 95%CI, 1.8 to 3.4) and maximal power (+21.3 W; 95%CI, 17.3 to 25.3) increased significantly in TG, whereas they were unchanged in CG (peak VO2: +0.2 mL.min-1.kg-1; 95%CI, -0.5 to 0.9 and maximal power: +0.7 W, 95%CI, -3.6 to 5.1) compared to values measured at T0. No correlation between LVEF changes and peak VO2 or maximal power was observed. Conclusion: A 12-week supervised exercise regimen was safe and improved the cardiopulmonary fitness in particular peak VO2, in HER2-positive BC patients treated with adjuvant trastuzumab therapy. The study is under powered to come to any conclusion regarding the effect on cardiotoxicity. Clinical trial registration: www.ClinicalTrials.gov, identifier: NCT02433067.

Subtle Combined Hamartoma of the Retina and Retinal Pigment Epithelium Causing Recurrent Exodeviation.

A 3-year-old girl presented with recurrent exotropia following primary strabismus surgery. Careful fundus examination of the left eye revealed loss of the foveal reflex and presence of a subtle grayish mass with overlying white fluff. Optical coherence tomography through the lesion revealed disorganization of inner and outer retinal layers with accompanying epiretinal gliosis. Together, these findings were suggestive of combined hamartoma of the retina and retinal pigment epithelium (CHRRPE). No syndromic association was found. CHRRPE is a rare retinal tumor that usually presents with visual loss, strabismus, or follows an asymptomatic course. Retinal tumors must be kept in mind whenever loss of foveal reflex occurs concurrently with strabismus.

Ventilatory adaptation during eccentric cycling in patients with severe COPD: Potential implications for exercise training.

INTRODUCTION: Eccentric (ECC) cycling is viewed as an alternative to concentric (CON) cycling for exercise training in patients with severe COPD as it induces a much lower ventilatory demand for a given mechanical load than CON cycling. However, a more hyperpneic breathing pattern (i.e., higher fB and lower tidal volume (VT)) during ECC than during CON has been reported in healthy subjects. RESEARCH QUESTION: Do patients with severe COPD develop a more hyperpneic breathing pattern during ECC than during CON cycling, and is it associated with differences in dynamic hyperinflation, ventilatory efficiency and cardiometabolic adaptation? METHODS: Fourteen patients with severe COPD performed incremental CON and ECC cardiopulmonary exercise tests (CPET). Several physiological parameters including VT, fB, inspiratory capacity (IC) and oxygen consumption (V̇O2) were recorded at each workload increment during CPET. RESULTS: At the highest identical minute ventilation (V̇E) achieved during ECC and CON (28.6 ± 4.6 L.min-1), VT was lower (1010 ± 218 vs. 1100 ± 233 mL; p = 0.02), fB was higher (29.0 ± 5.1 vs. 27.0 ± 5.5 min-1; p = 0.03), IC(% baseline) was lower (84 ± 10 vs. 78 ± 9; p < 0.01) and markers of ventilatory efficiency were poorer during ECC than during CON. Similar results were found at the highest identical V̇O2 achieved during ECC and CON. CONCLUSION: The finding of a more hyperpneic ventilatory pattern during ECC cycling together with a lower IC and a poorer ventilatory efficiency suggests that ECC exercise training should be decided with caution in patients with severe COPD.

Bacteria enhance the production of extracellular polymeric substances by the green dinoflagellate Lepidodinium chlorophorum.

High biomasses of the marine dinoflagellate Lepidodinium chlorophorum cause green seawater discolorations along Southern Brittany (NE Atlantic, France). The viscosity associated to these phenomena has been related to problems in oyster cultivation. The harmful effect of L. chlorophorum might originate from the secretion of Extracellular Polymeric Substances (EPS). To understand whether the EPS are produced by L. chlorophorum or its associated bacteria, or if they are a product of their interaction, batch cultures were performed under non-axenic and pseudo-axenic conditions for three strains. Maximum dinoflagellate cell abundances were observed in pseudo-axenic cultures. The non-sinking fraction of polymers (Soluble Extracellular Polymers, SEP), mainly composed of proteins and the exopolysaccharide sulphated galactan, slightly increased in pseudo-axenic cultures. The amount of Transparent Exopolymer Particles (TEP) per cell increased under non-axenic conditions. Despite the high concentrations of Particulate Organic Carbon (POC) measured, viscosity did not vary. These results suggest that the L. chlorophorum-bacteria interaction could have a detrimental consequence on the dinoflagellate, translating in a negative effect on L. chlorophorum growth, as well as EPS overproduction by the dinoflagellate, at concentrations that should not affect seawater viscosity.

Differentiation of groups of patients with cognitive complaints at breast cancer diagnosis: Results from a sub-study of the French CANTO cohort.

OBJECTIVE: Cognitive complaints are more frequent in women with breast cancer (BC) than in healthy controls and can be present before any treatment. Findings regarding contributive factors remain inconsistent. This study aimed to identify different groups of patients with cognitive complaints at BC diagnosis and to determine whether these different groups were associated with demographic, medical, or psychological characteristics. METHODS: Cognitive complaints were assessed in a subset of 264 women from the French multicenter prospective CANTO cohort, at baseline before any treatment. Clustering analyzes were performed using the six-cognitive dimension Costa's scoring of the FACT-Cog V3. Univariable analyses were used to study how cognitive function (standardized neuropsychological tests, ICCTF), anxiety, depression, fatigue, and quality of life (HADS, FA12, QLQ-C30) were associated with specific cognitive complaints groups. RESULTS: Results included 263 women (54±11 years), newly diagnosed with BC (69% stages I-III). Four distinct groups emerged, ranged from "no complaints" (22.8%), "low complaints" (55.1), "mixed complaints" (14.5%), to "consistent complaints" (7.6%). No significant differences were found in terms of demographic and medical factors between the four groups. However, the groups with higher proportions of patients with complaints were found to have more impairment in executive function, higher scores of anxiety, depressive symptoms, and fatigue, and lower quality of life, than the groups with lower proportions of cognitive complaints. CONCLUSION: Using complete cognitive assessment prior to BC treatment, we identified four distinct cognitive complaints groups with specific characteristics. This work provides valuable clinical basis to further investigations for a better understanding of cognitive complaints and their associates.

The spatial dimensions of medication management by home-dwelling older adults after hospital discharge.

Ageing in place raises pressing questions about medication practices at home. Understanding how medication practices are integrated into older adults' domestic settings requires an interest in where activities linked to medication take place and why. This study aimed to describe the medication practices and spatial dimensions of medication management for home-dwelling older adults after hospital discharge, using a qualitative research design. Semi-structured interviews were carried out with ten older adults aged 65 years old or more and discharged home from hospital, together with nine informal caregivers. Thematic content analysis identified two main themes dealing with the spatial dimensions of medication management in this specific context: the process of integrating medication changes into routines and familiar spaces, and the individual and collective management of medication changes linked to a renegotiation of the boundaries between public and private spaces.

Optimising medication management for polymedicated home-dwelling older adults with multiple chronic conditions: a mixed-methods study protocol.

INTRODUCTION: Optimal medication management is one of the basic conditions necessary for home-dwelling older adults living with multiple chronic conditions (OAMCC) to be able to remain at home and preserve their quality of life. Currently, the reasons for such high numbers of emergency department visits and the very significant rate of hospitalisations for OAMCC, due to medication-related problems (MRPs), is poorly explored. This study aims to reveal the current state of the medication management practices of polymedicated, home-dwelling OAMCC and to make proposals for improving clinical and medication pathways through an innovative and integrated model for supporting medication management and preventing adverse health outcomes. METHODS AND ANALYSIS: A mixed-methods study will address the medication management of polymedicated, home-dwelling OAMCC. Its explanatory sequential design will involve two major phases conducted sequentially over time. The quantitative phase will consist of retrospectively exploiting the last 5 years of electronic patient records from a local hospital (N ≈ 50 000) in order to identify the different profiles-made up of patient-related, medication-related and environment-related factors-of the polymedicated, home-dwelling OAMCC at risk of hospitalisation, emergency department visits, hospital readmission (notably for MRPs), institutionalisation or early death. The qualitative study will involve: (a) obtaining and understanding the medication management practices and experiences of the identified profiles extracted from the hospital data of OAMCC who will be interviewed at home (N ≈ 30); (b) collecting and analysing the perspectives of the formal and informal caregivers involved in medication management at home in order to cross-reference perspectives about this important dimension of care at home. Finally, the mixed-methods findings will enable the development of an innovative, integrated model of medication management based on the Agency for Clinical Innovation framework and Bodenheimer and Sinsky's quadruple aim. ETHICS AND DISSEMINATION: Ethical approval has been obtained from the Human Research Ethics Committee of the Canton Vaud (2018-02196). Findings will be disseminated in peer-reviewed journals, professional conferences and other knowledge transfer activities with primary healthcare providers, hospital care units, informal caregivers' and patients' associations.

Physiological and Metabolic Responses of Freshwater and Brackish-Water Strains of Microcystis aeruginosa Acclimated to a Salinity Gradient: Insight into Salt Tolerance.

Proliferation of microcystin (MC)-producing Microcystis aeruginosa in brackish waters has been described in several locations and represents a new concern for public and environmental health. While the impact of a sudden salinity increase on M. aeruginosa physiology has been studied, less is known about the mechanisms involved in salt tolerance after acclimation. This study aims to compare the physiological responses of two strains of M. aeruginosa (PCC 7820 and PCC 7806), which were isolated from contrasted environments, to increasing salinities. After acclimation, growth and MC production rates were determined and metabolomic analyses were conducted. For both strains, salinity decreased the biovolume, growth, and MC production rates and induced the accumulation of polyunsaturated lipids identified as monogalactosyldiacylglycerol. The distinct salt tolerances (7.5 and 16.9) obtained between the freshwater (PCC 7820) and the brackish-water (PCC 7806) strains suggested different strategies to cope with the osmotic pressure, as revealed by targeted and untargeted metabolomic analyses. An accumulation of trehalose as the main compatible solute was obtained in the freshwater strain, while sucrose was mainly accumulated in the brackish one. Moreover, distinct levels of glycine betaine and proline accumulation were noted. Altogether, metabolomic analysis illustrated a strain-specific response to salt tolerance, involving compatible solute production.IMPORTANCE Blooms of Microcystis aeruginosa and the production of microcystins are major issues in eutrophic freshwater bodies. Recently, an increasing number of proliferations of M. aeruginosa in brackish water has been documented. The occurrence of both M. aeruginosa and microcystins in coastal areas represents a new threat for human and environmental health. In order to better describe the mechanisms involved in Microcystis sp. proliferation in brackish water, this study used two M. aeruginosa strains isolated from fresh and brackish waters. High salinity reduced the growth rate and microcystin production rate of M. aeruginosa In order to cope with higher salinities, the strains accumulated different cyanobacterial compatible solutes, as well as unsaturated lipids, explaining their distinct salt tolerance.

A challenging diagnosis of exercise-related transient abdominal pain.

A 17-year-old woman, high-performance triathlete, presented transient abdominal pain, face angioedema and sometimes syncope during exercise. Exercise-induced anaphylaxis was suspected at first. Allergic explorations with skin prick tests were negative but wheat flour specific IgE and recombinant rTri a14 (LTP) were weakly positive. However, wheat eviction did not improve the symptoms and stress test after wheat oral challenge did not show any signs of anaphylaxis. An abdominal ultrasound revealed peak expiratory velocities with a stenosis evaluated at 70 to 80 percent with turbulences in the celiac artery, confirmed by computed tomography angiogram. The diagnosis of exercise-induced median arcuate ligament syndrome (MALS) was retained and we discuss here the challenging diagnosis mimicking exercise-induced anaphylaxis.

Medication Management Models for Polymedicated Home-Dwelling Older Adults With Multiple Chronic Conditions: Protocol of a Systematic Review.

BACKGROUND: Older adults with multiple chronic diseases commonly require complex medication regimes. When combined with frailty, cognitive impairment, and changing pharmacological prescriptions, older adults' polymedication regimes increase the risk of medication-related problems (MRPs) and hospitalization. Effective, well-organized medication management could avoid MRPs and their clinical outcomes. OBJECTIVE: Identify medication management models and analyze their impact on managing and preventing MRPs for polymedicated, home-dwelling older adults. METHODS: We will conduct a systematic review of published articles in relevant professional scientific journals from inception until March 31, 2019, in the following electronic databases,: Embase; Medline OvidSP; PubMed (NOT Medline[sb]); Cumulative Index to Nursing and Allied Health Literature (CINAHL) EBSCO; PsycINFO OvidSP; Cochrane Library, Wiley; and Web of Science. We will also hand search the bibliographies of all the relevant articles found and search for unpublished studies. We will consider publications in English, French, German, Spanish, Italian, and Portuguese. Retrieved articles will be screened for eligibility. Statistical analyses will be conducted following the recommendations of the Cochrane Handbook for Systematic Reviews of Interventions, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), and Meta-analysis Of Observational Studies in Epidemiology (MOOSE) statements. Data will be analyzed using SPSS Statistics for Windows, version 25.0 (IBM Corp), and Review Manager, version 5.5 (The Nordic Cochrane Centre, The Cochrane Collaboration). RESULTS: A preliminary search in Embase delivered 3272 references. This preliminary search allows us to complete our research strategy with equation development and to search the other databases. Relevant articles identified will allow for searching the reference lists for unpublished studies. The inclusion and exclusion criteria will be rigorously respected in the study selection. The entire study is expected to be completed by January 2020. CONCLUSIONS: This review will provide an exhaustive view of medication management models that could be effective for polymedicated, home-dwelling older adults and will allow us to analyze their impact on managing and preventing MRPs.

Tubular and mucinous breast cancer: results of a cohort of 917 patients.

OBJECTIVES:: To analyze axillary lymph node involvement (ALNI) rate and survival for mucinous (MC) and tubular (TC) breast carcinomas considered being of very good prognosis and for which an axillary surgical exploration could be questioned. METHODS:: Our multicentric cohort consisted of 21,135 patients with clinically node-negative invasive breast cancer, without neoadjuvant therapy, between 1999 and 2013 in 10 French centers. ALNI rate and survival were analyzed according to patient and tumor characteristics. RESULTS:: Our cohort consisted of 672 TC and 245 MC. Patients were older and tumor size greater for MC and pathologic factors were more pejorative. The rate of mastectomies and adjuvant chemotherapy was higher in the MC group. Axillary lymph node status was determined by SLNB alone in 71.2% of patients. ALNI rates were 17.9% and 18% for TC and MC, respectively. ALNI rate was lesser for MC (OR 0.503, p = 0.024) and greater in case of lympho-vascular invasion (OR 5.0, p < 0.0001) and for tumors >10 mm (OR 2.17, p = 0.042). Median follow-up was 58 months. The 5- and 7-year overall survival rates were 97.1% and 95% for TC, respectively; 92.3% and 91.2% for MC ( p = 0.043); 5- and 7-year disease-free survival rates were 97.9% and 97.2% versus 95.2 and 93.6% ( p = 0.041). Lympho-vascular invasion was the only predictive factor for overall survival (hazard ratio [HR] = 2.70)' grade 2 (HR = 10) and HR-negative (HR = 4.9) were the two predictive factors for disease-free survival. CONCLUSION:: This study confirms the need for an axillary exploration for these tumors even for a tumor size <10 mm and a favorable prognosis.

Medication practices and experiences of older adults discharged home from hospital: a feasibility study protocol.

BACKGROUND: Switzerland's aging population raises pressing questions about maintaining older adults in their home environments and the problems associated with managing complex treatments requiring medication in such contexts. Few studies have examined older adults' experiences of changes in their medication on discharge home following hospitalization for illness or an accident. Similarly, few studies have evaluated the involvement of informal and professional caregivers in the medication practices used with older adults living at home. However, medication practices are complex and understanding them requires an interest in their underlying logic and the interactions that constitute them. This study will explore the feasibility of recruiting older adults and then collecting and analyzing data on their medication practices and their experiences of discharge home after hospitalization for an illness or following an accident. Furthermore, it will describe the involvement of informal caregivers and homecare professionals in these processes. DESIGN AND METHODS: The study will use a qualitative methodology. The first phase will be developed in the general medicine and surgery wards of Sion hospital and in the town's community healthcare center. This phase will aim to build a close collaboration between the research team and the health care professionals of Valais hospitals and the community healthcare center. It will enable data collection from professional caregivers to identify the tools, and potentially the interventions, which are used to prepare older adults for hospital discharge and return home, particularly with regard to the medication prescribed to them. In the second phase, semi-structured interviews will be conducted with eight patients aged 75 years old or more who have returned home after hospitalization. Interviews will also be conducted with their informal and professional caregivers. CONCLUSION: This feasibility study will enable the identification of tools that leverage improved adhesion to a medical treatment that has been adjusted and stabilized following discharge home from hospital. It will incorporate the points of view of older adults and the different stakeholders involved in the management of their medication and the development of tangible solutions to encourage treatment adhesion on discharge home. This study's findings will enable us to design a much larger future study.

Factors associated with a poor prognosis for the IVF-ICSI live birth rate in women with rAFS stage III and IV endometriosis.

PURPOSE: To assess the factors associated with a poor prognosis for a cumulative IVF live birth rate (LBR) in women with stage III and IV endometriosis according to the revised classification of the American Fertility Society (rAFS). METHODS: A retrospective cohort study was conducted between January 1, 2010, and December 31, 2014, in our Reproductive Medicine Center. We analyzed different factors associated with a poor prognosis for a cumulative IVF LBR in women with rAFS stage III and IV endometriosis. A total of 101 patients were included, representing 232 IVF-ICSI cycles and 212 embryo transfers. The primary endpoint was the cumulative LBR per cycle and per patient. RESULTS: The cumulative LBR per cycle was 14.7% (n = 34) and that per patient was 31.7% (n = 32). The cumulative LBR was significantly decreased by active smoking [adjOR = 3.4, 95% CI (1.12-10.60), p = 0.031], poor ovarian response (POR) according to the Bologna criteria [adjOR = 11.5, 95% CI (1.37-96.83), p = 0.024], and rAFS stage IV [adjOR = 3.2, 95% CI (1.13-8.95), p = 0.024]. The cumulative LBR per women was 59.4% without factors associated with a poor prognosis and 25.6% in the case of one factor, and it decreased to 7.7% in the case of two or three factors (p < 0.001). CONCLUSION: Active smoking, POR according to the Bologna criteria, and rAFS stage IV endometriosis had a negative impact on the IVF-ICSI cumulative LBR for women with rAFS stage III and IV endometriosis. Because smoking dramatically decreases the LBR with endometriosis, stopping smoking before IVF-ICSI should be strongly advised.

Smoking habits in French farmers: a cross-sectional study.

BACKGROUND: Farmers are exposed to multiple air contaminants that may interact with tobacco smoking in the development of respiratory diseases. Farmers are currently considered to smoke less than non-farmers, but precise data in different categories of age and farming activities are lacking. METHODS: Smoking habits were studied in a cross-sectional study involving 4105 farmers and 996 non-farming controls aged 40-74 years in 9 French departments between October 2012 and May 2013. Three age groups were defined (40-54, 55-64 and 65-74years). Farmers were divided into four activity groups, namely cattle breeders, livestock farmers working in confined spaces, crop farmers and others. Smoking prevalence was compared between farmers and controls, and odds ratios (ORs) for smoking adjusted for age were calculated. RESULTS: The adjusted OR for ever-smoking was lower among farmers than among non-farmers in all age categories, but the ORs for current smoking were similar in farmers and controls. Smoking prevalence varied according to the type of farming activity, and was lower than in non-farming controls only among cattle breeders and confined livestock farmers. In farmers, the proportion of smokers was higher in the youngest age categories compared with the older age classes. CONCLUSIONS: Our results confirm that the prevalence of ever-smokers is lower in farmers than in non-farmers. Nevertheless, our data show that active smoking prevalence is similar in farmers and in non-farmers. This suggests that farmers, just like non-farmers, should be targeted by primary prevention campaigns against smoking.
