Concurrent or Sequential Adjuvant Letrozole and Radiotherapy after Conservative Surgery for Early-stage Breast Cancer: Long-term Results of the Cohort Phase 2 Randomized Trial

Purpose/Objective(s): Letrozole radiosensitizes breast cancer cells in vitro. In clinical settings, no data exist for the combination of letrozole and radiotherapy. We assessed concurrent and sequential radiotherapy and letrozole in the adjuvant setting.Materials/Methods: The present study is registered with ClinicalTrials.gov, number NCT00208273. This Phase 2 randomized trial was undertaken in two centers in France and one in Switzerland between January 12, 2005, and February 21, 2007. One hundred fifty postmenopausal women with early-stage breast cancer were randomly assigned after conserving surgery to either concurrent radiotherapy and letrozole (n = 75) or sequential radiotherapy and letrozole (n = 75). Randomization was open label with a minimization technique, stratified by investigational centers, chemotherapy (yes vs. no), radiation boost (yes vs. no), and value of radiation-induced lymphocyte apoptosis (#16% vs. .16%). The whole breast was irradiated to a total dose of 50 Gy in 25 fractions over 5 weeks. In the case of supraclavicular and internal mammary node irradiation, the dose was 44 - 50 Gy. Letrozole was administered orally once daily at a dose of 2 - 5 mg for 5 years (beginning 3 weeks pre-radiotherapy in the concomitant group, and 3 weeks postradiotherapy in the sequential group). The primary endpoint was the occurrence of acute (during and within 6 weeks of radiotherapy) and late (within 2 years) radiation-induced Grade 2 or worse toxic effects of the skin and lung (functional pulmonary test and lung CT-scan). Analyses were by intention-to-treat. The long-term follow-up after 2 years was only performed in Montpellier (n = 121) and evaluated skin toxicity (clinical examination every 6 months), lung fibrosis (one CT-scan yearly), cosmetic outcome.Results: All patients were analyzed apart from 1 in the concurrent group who withdrew consent before any treatment.Within the first 2 years (n = 149), no lung toxicity was identified by CT scan and no modification from baseline was noted by the lung diffusion capacity test. Two patients in each group had Grade 2 or worse late effects (both radiation-induced subcutaneous fibrosis [RISF]). After 2 years (n = 121), and with a median follow-up of 50 months (38-62), 2 patients (1 in each arm) presented a Grade 3 RISF. No lung toxicity was identified by CT scan. Cosmetic results (photographies) and quality of life was good to excellent. All patients who had Grade 3 subcutaneous fibrosis had an RILA value of 16% or less, irrespective of the sequence with letrozole.Conclusions:With long-term follow-up, letrozole can be safely delivered shortly after surgery and concomitantly with radiotherapy.

Ultra-rapid opiate detoxification using deep sedation and prior oral buprenorphine preparation: long-term results.

BACKGROUND: New methods of ultra-rapid opiate detoxification (URD) under intravenous sedation have been criticized because of limited data on safety and long-term follow-up. Premedication with buprenorphine has been advocated to improve safety by decreasing vomiting. Prior research has not explored URD in socially impaired patients. METHOD: Sixteen patients were detoxified with URD and prospectively evaluated over at least 30 months. Data of this procedure were compared with those of our previous study without buprenorphine preparation (Drug Alcohol Depend. 52(3) (1998) 243). The 16 patients were followed up by a general practitioner (GP) before and after URD. The GPs also supervised the 7-day course of buprenorphine treatment prescribed for the 16 patients prior to URD. RESULTS: During the procedure, only one episode of vomiting occurred instead of 13 out of 20 in our previous study. Post-procedure, only two patients experienced moderate withdrawal symptoms, such as persistent nausea, abdominal cramps and vomiting lasting from 24 to 48 h, in comparison with most patients in the previous study without buprenorphine. After a period of at least 30 months (36.0+/-6.38), the 16 patients were still alive and were regularly monitored by their GP. Only two of the 16 never relapsed after URD and reported total opiate abstinence. Fourteen patients relapsed; 12 of these were prescribed a licensed methadone substitution program and two were still using heroin. CONCLUSION: In this small sample, the data indicated that URD with buprenorphine preparation was safe and that it markedly decreased post-procedure morbidity. No patient died over a minimum 30-month follow-up period. Furthermore, the procedure was employed with socially impaired patients. In the long term, a few patients were still free of opiates, while the majority opted for a methadone maintenance program, showing that URD can serve as one possible step in a long-term treatment program.

Baerveldt implant in refractory glaucoma: long-term results and factors influencing outcome.

PURPOSE: To evaluate the clinical outcome of patients who received a Baerveldt implant for refractory glaucoma and to identify factors which may influence the outcome. METHODS: Retrospective study including 51 eyes of 51 patients with medically uncontrolled glaucoma who underwent Baerveldt implant surgery between June 1994 and December 1998. Criteria for success were intraocular pressure (IOP) < or = 21 mmHg and > 6 mmHg, necessity of further antiglaucoma medications, absence of additional glaucoma surgery and no loss of light perception. RESULTS: Over a mean follow-up of 37.6 (SD: +/-18.8) months, the mean intraocular pressure decreased from 34.8 (+/-12.5) mmHg to 14.0 (+/-4.3) mmHg at month 60. Qualified success rate, achieved when IOP was below 21 mmHg and higher than 6 mmHg with medications was 25/48 (52%), complete success rate (same IOP limits without medication) was 14/48 (29%). Seven eyes had major complications or lost light perception. Postoperative visual acuity improved or remained within one Snellen line of the preoperative visual acuity in 35 patients (73%). Factors associated with a better prognosis were a preoperative visual acuity better than 20/400 and etiology of glaucoma. CONCLUSION: The Baerveldt implant is effective in lowering intraocular pressure in most patients with refractory glaucoma. Long-term results are promising with satisfactory IOP control.

Long-term effects of neonatal hypoglycemia on brain growth and psychomotor development in small-for-gestational-age preterm infants.

OBJECTIVE: To investigate the effects of neonatal hypoglycemia on physical growth and neurocognitive function.Study design: A systematic detection of hypoglycemia (<2.6 mmol/L or 47 mg/dL) was carried out in 85 small-for-gestational-age preterm neonates. Prospective serial evaluations of physical growth and psychomotor development were performed. Retrospectively, infants were grouped according to their glycemic status. RESULTS: The incidence of hypoglycemia was 72.9%. Infants with repeated episodes of hypoglycemia had significantly reduced head circumferences and lower scores in specific psychometric tests at 3.5 years of age. Hypoglycemia also caused reduced head circumferences at 18 months and lower psychometric scores at 5 years of age. Infants with moderate recurrent hypoglycemia had lower scores at 3.5 and 5 years of age compared with the group of infants who had 1 single severe hypoglycemic episode. CONCLUSION: Recurrent episodes of hypoglycemia were strongly correlated with persistent neurodevelopmental and physical growth deficits until 5 years of age. Recurrent hypoglycemia also was a more predictable factor for long-term effects than the severity of a single hypoglycemic episode. Therefore repetitive blood glucose monitoring and rapid treatment even for mild hypoglycemia are recommended for small-for-gestational-age infants in the neonatal period.

Long-Term Follow-Up of Multilayer Amniotic Membrane Transplantation (MLAMT) for Non-Traumatic Corneal Perforations or Deep Ulcers with Descemetocele.

Background: To evaluate the long-term efficacy of multilayer amniotic membrane transplantation for reconstruction of epithelium and stroma in non-traumatic corneal perforations (less than 2 mm) or deep ulcers with descemetocele.Design: Retrospective, non-comparative, interventional case series.Patients and Methods: Eleven consecutive patients with non-traumatic corneal perforations or deep corneal ulcers with descemetocele refractory to conventional treatments: herpetic or zoster keratitis (n = 4), Sjögren's syndrome (n = 2), rosacea (n = 1), hydrops (n = 1), mucous membrane pemphigoid (n = 1), bacterial keratitis (n = 1) and perforation after protontherapy for melanoma (n = 1). Intervention was: multilayer amniotic membrane transplantation with cryopreserved amniotic membrane. Complication rate and clinical outcome were evaluated in this long-term follow-up.Results: Mean follow-up was 32 months (12 to 60). Integration of the multilayer amniotic membrane was obtained in 10 cases after one year. Corneal epithelium healed above the membrane in 10 cases within 3 weeks and remained stable after 32 months in 9 cases. Thickness of the stroma was increased and remained stable during the follow-up in 9 cases. In one case herpetic keratitis recurred with a corneal perforation. The clearing of the amniotic membrane was gradually obtained over a period of 11 months. Complications occurred in 15 % of the eyes during the long-term follow-up.Conclusion: Multilayer amniotic membrane transplantation is a safe and efficient technique for a long restoration of the corneal integrity after non-traumatic corneal perforations or deep corneal ulcers with descemetocele. Long-term prognosis of these eyes depends of the gravity of the initial disease.

Design and methodology of the Swiss Transplant Cohort Study (STCS): a comprehensive prospective nationwide long-term follow-up cohort.

In Switzerland, organ procurement is well organized at the national-level but transplant outcomes have not been systematically monitored so far. Therefore, a novel project, the Swiss Transplant Cohort Study (STCS), was established. The STCS is a prospective multicentre study, designed as a dynamic cohort, which enrolls all solid organ recipients at the national level. The features of the STCS are a flexible patient-case system that allows capturing all transplant scenarios and collection of patient-specific and allograft-specific data. Beyond comprehensive clinical data, specific focus is directed at psychosocial and behavioral factors, infectious disease development, and bio-banking. Between May 2008 and end of 2011, the six Swiss transplant centers recruited 1,677 patients involving 1,721 transplantations, and a total of 1,800 organs implanted in 15 different transplantation scenarios. 10 % of all patients underwent re-transplantation and 3% had a second transplantation, either in the past or during follow-up. 34% of all kidney allografts originated from living donation. Until the end of 2011 we observed 4,385 infection episodes in our patient population. The STCS showed operative capabilities to collect high-quality data and to adequately reflect the complexity of the post-transplantation process. The STCS represents a promising novel project for comparative effectiveness research in transplantation medicine.

Long-Term Follow-Up of Choroidal Neovascularization in Pathological Myopia Treated with Intravitreal Ranibizumab.

Background: The purpose of this contribution is to report our functional results on the efficacy of intravitreal ranibizumab for submacular choroidal neovessels (CNV) in high myopia, and to compare the roles of optical coherence tomography (OCT), fluorescein angiography and visual acuity changes in the treatment decision prior to each injection. Patients and Methods: This is a retrospective study performed in Jules Gonin Eye Hospital. It included all patients with myopic CNV treated with intravitreal ranibizumab injections with a minimum follow-up of 24 months. After an induction dosing from 1 to 3 injections, the follow-up was based on a pro re nata regimen. Ophthalmic evaluation, best corrected visual acuity, and OCT were done at each visit, and fluorescein angiography at baseline and if neovascular activity was suspected. Retreatment criteria included metamorphopsia, visual loss of ≥ 5 ETDRS letters, any fluid on OCT and/or leakage on fluorescein angiography. Results: 24 eyes were included in the study. Mean follow-up was 49 months. Mean visual acuity improved significantly from 62.8 ± 13.8 letters at baseline to 72.8 ± 12.9 letters at last follow-up visit (p = 0.001). The mean number of injections was 2.2 in the first year and below 1 for the following years. The sensitivities of fluorescein angiography, SD OCT, and visual acuity loss ≥ 5 letters were 62.6 %, 51.4 %, and 40 %, respectively. The fluorescein angiography showed a significantly higher sensitivity in treatment decision than OCT (p = 0.007). Conclusion: Our study has shown that ranibizumab injections provide a significant long-term visual benefit in myopic CNV with a small number of injections. Fluorescein angiography has a preponderant role in the treatment decision of active myopic CNV.

Long-term continuous-flow left ventricular assist devices (LVAD) as bridge to heart transplantation.

Heart transplantation (HTx) is the treatment of choice for end-stage heart failure but the limited availability of heart's donors still represents a major issue. So long-term mechanical circulatory support (MCS) has been proposed as an alternative treatment option to assist patients scheduled on HTx waiting list bridging them for a variable time period to cardiac transplantation-the so-called bridge-to-transplantation (BTT) strategy. Nowadays approximately 90% of patients being considered for MCS receive a left ventricular assist device (LVAD). In fact, LVAD experienced several improvements in the last decade and the predominance of continuous-flow over pulsatile-flow technology has been evident since 2008. The aim of the present report is to give an overview of continuous-flow LVAD utilization in the specific setting of the BTT strategy taking into consideration the most representative articles of the scientific literature and focusing the attention on the evolution, clinical outcomes, relevant implications on the HTx strategy and future perspectives of the continuous-flow LVAD technology.

Chronic NSAID use and long-term decline of renal function in a prospective rheumatoid arthritis cohort study.

OBJECTIVES: Non-steroidal anti-inflammatory drugs (NSAIDs) may cause kidney damage. This study assessed the impact of prolonged NSAID exposure on renal function in a large rheumatoid arthritis (RA) patient cohort. METHODS: Renal function was prospectively followed between 1996 and 2007 in 4101 RA patients with multilevel mixed models for longitudinal data over a mean period of 3.2 years. Among the 2739 'NSAID users' were 1290 patients treated with cyclooxygenase type 2 selective NSAIDs, while 1362 subjects were 'NSAID naive'. Primary outcome was the estimated glomerular filtration rate according to the Cockroft-Gault formula (eGFRCG), and secondary the Modification of Diet in Renal Disease and Chronic Kidney Disease Epidemiology Collaboration formula equations and serum creatinine concentrations. In sensitivity analyses, NSAID dosing effects were compared for patients with NSAID registration in ≤/>50%, ≤/>80% or ≤/>90% of assessments. FINDINGS: In patients with baseline eGFRCG >30 mL/min, eGFRCG evolved without significant differences over time between 'NSAID users' (mean change in eGFRCG -0.87 mL/min/year, 95% CI -1.15 to -0.59) and 'NSAID naive' (-0.67 mL/min/year, 95% CI -1.26 to -0.09, p=0.63). In a multivariate Cox regression analysis adjusted for significant confounders age, sex, body mass index, arterial hypertension, heart disease and for other insignificant factors, NSAIDs were an independent predictor for accelerated renal function decline only in patients with advanced baseline renal impairment (eGFRCG <30 mL/min). Analyses with secondary outcomes and sensitivity analyses confirmed these results. CONCLUSIONS: NSAIDs had no negative impact on renal function estimates but in patients with advanced renal impairment.

The offspring of the diabetic mother--short- and long-term implications.

In the 1980s, David Barker and Colleagues proposed that the major causes of cardiovascular and metabolic diseases have their roots in early development. There is now robust evidence that an hyperglycemic intrauterine environment is responsible not only for significant short-term morbidity in the fetus and the neonate but also for an increased risk of developing diabetes as well as other chronic, noncommunicable diseases at adulthood. The risk is higher in pregestational diabetes, but unrecognized and/or poorly managed gestational diabetes (GDM) may have similar consequences. Although a relatively clear picture of the pathogenesis of the fetal and neonatal complications of maternal diabetes and of their interrelationship is available today, the intimate molecular mechanisms involved in the long term are far from being understood. While the rate of GDM is sharply increasing in association with the pandemic of obesity and of type 2 diabetes over the world, we review here the current understanding of short- and long-term outcomes of fetuses exposed to a diabetic environment.

Human cytomegalovirus induced pseudotumor of upper gastrointestinal tract mucosa: Effects of long-term chronic disease?

Human cytomegalovirus-induced lesions resembling malignancies have been described in the gastrointestinal tract and include ulcerated or exophytic large masses. The aim of this study was to review the cases registered in the databases of two academic hospitals and formulate a hypothesis concerning the pathogenic mechanisms responsible for cytomegalovirus-induced pseudotumor development. All the diagnoses of human cytomegalovirus infections of the upper gastrointestinal tract recorded from 1991 to 2013 were reviewed. Cases of mucosal alterations misdiagnosed endoscopically as malignancies were selected. Large ulcers occurring in the stomach (three cases) and an irregular exophytic mass at the gastro-jejunal anastomosis were misdiagnosed endoscopically as malignancies (4 cases out of 53). Histologically, all lesions reflected hyperplastic mucosal changes with a prevalence of epithelial and stroma infected cells, without signs of cell atypia. The hypothesis presented is that the development of human cytomegalovirus-induced pseudotumors may be the morphological expression of chronic mucosa damage underlying long-term infection.

Psychosexual development in men with congenital hypogonadotropic hypogonadism on long-term treatment: a mixed methods study.

INTRODUCTION: Congenital hypogonadotropic hypogonadism (CHH) is a rare, genetic, reproductive endocrine disorder characterized by absent puberty and infertility. Limited information is available on the psychosocial impact of CHH and psychosexual development in these patients. AIM: The aim of this study was to determine the impact of CHH on psychosexual development in men on long-term treatment. METHODS: A sequential mixed methods explanatory design was used. First, an online survey (quantitative) was used to quantify the frequency of psychosexual problems among CHH men. Second, patient focus groups (qualitative) were conducted to explore survey findings in detail and develop a working model to guide potential nursing and interdisciplinary interventions. MAIN OUTCOME MEASURES: Patient characteristics, frequency of body shame, difficulty with intimate relationships, and never having been sexually active were assessed. Additionally, we collected subjective patient-reported outcomes regarding the impact of CHH on psychological/emotional well-being, intimate relationships, and sexual activity. RESULTS: A total of 101 CHH men on long-term treatment (>1 year) were included for the analysis of the online survey (mean age 37 ± 11 years, range 19-66, median 36). Half (52/101, 51%) of the men had been seen at a specialized academic center and 37/101 (37%) reported having had fertility-inducing treatment. A high percentage of CHH men experience psychosexual problems including difficulty with intimate relationships (70%) and body image concerns/body shame (94/101, 93%), and the percentage of men never having been sexually active is five times the rate in a reference group (26% vs. 5.4%, P < 0.001). Focus groups revealed persisting body shame and low self-esteem despite long-term treatment that has lasting impact on psychosexual functioning. CONCLUSIONS: CHH men frequently experience psychosexual problems that pose barriers to intimate relationships and initiating sexual activity. These lingering effects cause significant distress and are not ameliorated by long-term treatment. Psychosexual assessment in CHH men with appropriate psychological support and treatment should be warranted in these patients. Dwyer AA, Quinton R, Pitteloud N, and Morin D.
