The POSITIVE study investigates the impact of temporary ET interruption to allow pregnancy. Methods POSITIVE enrolled women with stage I-III HR + early breast cancer, ≤42 years, who had received 18–30 months of adjuvant ET and wished to interrupt ET for pregnancy. Treatment interruption for up to 2 years was permitted to allow pregnancy, delivery and breastfeeding, followed by ET resumption to complete the planned duration. Findings From 12/2014 to 12/2019, 518 women were enrolled at 116 institutions/20 countries/4 continents. At enrolment, the median age was 37 years and 74.9 % were nulliparous. Fertility preservation was used by 51.5 % of women. 93.2 % of patients had stage I/II disease, 66.0 % were node-negative, 54.7 % had breast conserving surgery, 61.9 % had received neo/adjuvant chemotherapy. Tamoxifen alone was the most prescribed ET (41.8 %), followed by tamoxifen + ovarian function suppression (OFS) (35.4 %). A greater proportion of North American women were <35 years at enrolment (42.7 %), had mastectomy (59.0 %) and received tamoxifen alone (59.8 %). More Asian women were nulliparous (81.0 %), had node-negative disease (76.2%) and received tamoxifen + OFS (56.0 %). More European women had received chemotherapy (69.3 %). Interpretation The characteristics of participants in the POSITIVE study provide insights to which patients and doctors considered it acceptable to interrupt ET to pursue pregnancy. Similarities and variations from a regional, sociodemographic, disease and treatment standpoint suggest specific sociocultural attitudes across the world.The POSITIVE trial and this work are sponsored by the IBCSG in non-North American countries and by the Alliance for Clinical Trials in Oncology in North America, with collaboration of the Breast International Group (BIG) cooperative groups and US National Clinical Trials Network groups

Prevalence of diabetes mellitus and impaired glucose regulation in Spain: the [email protected] Study

Introduction: atherosclerosis, blood vessel disease, is the main cause of cardiovascular disease associated with aging; comprising modifiable risk factors that increase because of this when it exists.Objective: to evaluate atherogenic markers and metabolic syndrome in older adults, with cardiovascular risk living in urban areas, Pinar del Río province. Methods: observational, descriptive and cross-sectional study, from the service of Clinical Laboratory at Abel Santamaría Cuadrado Teaching General Hospital  Pinar del Río with 60 years old and older patients from the urban areas, during the period 2013 - 2014. The target group included 588 patients. The sample comprised 100 patients who have at least two risk factors previously established for this study.Results: ample predominance of women (61.0 %), the risk factors of higher incidence were hypertension 67 %, and sedentary lifestyle 65 %, followed by obesity 48 %, diabetes mellitus 40 % along with smoking habit 32 %, obese with increased diameters of waist circumference 48 %, and dyslipidemia 49 %, those with high glycemic values in fasting 50 % of the sample. It was considered that 63 % of the patients studied suffer from metabolic syndrome.Conclusions: a high number of white-skin women, the predominant risk factors were hypertension followed by sedentary lifestyle, obesity, diabetes mellitus and smoking habit. Approximately half of the sample was obese with increased diameters of the waist circumference, a large part suffered from dyslipidemia and half of them showed high fasting blood glucose levels. The prevalence of metabolic syndrome was detected.IIntroducción: aterosclerosis, enfermedad de los vasos sanguíneos, principal causa de enfermedad cardiovascular vinculada al envejecimiento, con factores de riesgo modificables que se incrementan cuando esta existe.Objetivo: evaluar marcadores aterogénicos y síndrome metabólico en adultos mayores, con riesgo cardiovascular residentes en zonas urbanas de la provincia Pinar del Río.Métodos: estudio observacional, descriptivo, transversal, servicio de Laboratorio Clínico Hospital General Docente “Abel Santamaría Cuadrado” Pinar del Río, pacientes de 60 años y más de zonas urbanas, durante período 2013 - 2014. Universo de 588 pacientes. Muestra de 100 pacientes que posean mínimo de dos factores de riesgo establecidos con anterioridad para este estudio.Resultados: amplio predominio de las mujeres (61 %). Factores de riesgo de mayor incidencia hipertensión arterial 67 %, y sedentarismo 65 %, seguidos por obesidad 48 %, diabetes mellitus 40 % y hábito de fumar 32 %, obesos con diámetros aumentados de la circunferencia de la cintura 48 %, presentaban dislipidemia 49 % y tenían elevados valores de glucemia en ayunas el 50 % de la muestra. Se consideró que 63 % de los pacientes estudiados presentaron síndrome metabólico.Conclusiones: elevado número de mujeres de piel blanca, con factor de riesgo predominante de hipertensión arterial seguido por sedentarismo, obesidad, diabetes mellitus y hábito de fumar. Alrededor de la mitad de la muestra fueron obesos con diámetros aumentados de la circunferencia de la cintura, gran parte presentaban dislipidemia y la mitad altos valores de glucemia en ayunas. Se detecta prevalencia de síndrome metabólico

Identification of Novel Pathogenicity Loci in Clostridium perfringens Strains That Cause Avian Necrotic Enteritis

Type A Clostridium perfringens causes poultry necrotic enteritis (NE), an enteric disease of considerable economic importance, yet can also exist as a member of the normal intestinal microbiota. A recently discovered pore-forming toxin, NetB, is associated with pathogenesis in most, but not all, NE isolates. This finding suggested that NE-causing strains may possess other virulence gene(s) not present in commensal type A isolates. We used high-throughput sequencing (HTS) technologies to generate draft genome sequences of seven unrelated C. perfringens poultry NE isolates and one isolate from a healthy bird, and identified additional novel NE-associated genes by comparison with nine publicly available reference genomes. Thirty-one open reading frames (ORFs) were unique to all NE strains and formed the basis for three highly conserved NE-associated loci that we designated NELoc-1 (42 kb), NELoc-2 (11.2 kb) and NELoc-3 (5.6 kb). The largest locus, NELoc-1, consisted of netB and 36 additional genes, including those predicted to encode two leukocidins, an internalin-like protein and a ricin-domain protein. Pulsed-field gel electrophoresis (PFGE) and Southern blotting revealed that the NE strains each carried 2 to 5 large plasmids, and that NELoc-1 and -3 were localized on distinct plasmids of sizes ∼85 and ∼70 kb, respectively. Sequencing of the regions flanking these loci revealed similarity to previously characterized conjugative plasmids of C. perfringens. These results provide significant insight into the pathogenetic basis of poultry NE and are the first to demonstrate that netB resides in a large, plasmid-encoded locus. Our findings strongly suggest that poultry NE is caused by several novel virulence factors, whose genes are clustered on discrete pathogenicity loci, some of which are plasmid-borne

Influence of dietary fat source, alpha-tocopherol, and ascorbic acid supplementation on sensory quality of dark chicken meat

8 pages, 2 figures, 5 tables.-- PMID: 11441849 [PubMed].We studied the influence of dietary fat source and dl-α-tocopheryl acetate and ascorbic acid supplementation on the sensory quality of cooked dark chicken meat stored at −20 C for different periods. Results showed that dietary fat source and α-tocopheryl acetate supplementation influenced sensory scores (rancid flavor and aroma and acceptability). Ascorbic acid had no influence on these scores. Thiobarbituric acid values showed a high correlation with sensory scores. In addition, the low levels of α-tocopheryl acetate contained in the trace mineral-vitamin mix (20 IU/kg of feed) were enough to prevent rancidity development in cooked dark chicken meat when broilers were fed a saturated fat diet and samples were vacuum-packed and stored at −20 C for 13 mo.This work was supported by research grants from the Comisio´n Interministerial de Ciencia y Tecnologı´a (CICYT) and the Instituto Danone.Peer reviewe
