Evaluation of the Effectiveness of Breastfeeding as a Factor in the Prevention of Breast Cancer

2020

Background: As cancer is one of the main causes of fatal illnesses in the world, and breast cancer is responsible for an elevated number of deaths in women, it is important to implement measures to prevent this disease. Method: In order to assess the influence of breastfeeding in preventing breast cancer in women, forteen prospective cohort articles are included in this study, and their methodological quality has been assessed through the Newcastle Ottawa quality assessment scale cohort studies. After determining the risk of bias for each case study, those with fewer systematic errors and therefore greater validity, have been selected to demonstrate the relationship they propose exists bet…

Low risk of severe hypoglycaemia in patients with type 2 diabetes mellitus starting insulin therapy with premixed insulin analogues BID in outpatient…

2012

Summary Aims:  The choice of insulin at initiation in type 2 diabetes remains controversial. The aim of this study was to assess the occurrence of self-reported severe hypoglycaemia associated with premixed insulin analogues in routine clinical care. Methods:  A 12-month, prospective, observational, multicentre study in patients starting a commonly prescribed premixed insulin analogue (either insulin lispro 25/75 or biphasic insulin aspart 30/70, twice daily) after suboptimal glycaemic control on oral antidiabetic agents. Treatment decisions were made solely in the course of usual practice. Results:  Study follow-up was completed by 991 (85.5%) of the 1150 patients enrolled. At baseline, me…

Los niveles plasmáticos de IL-18 se relacionan con la insulinemia y están modulados por polimorfismos del gen de IL-18

2015

INTRODUCTION Atherosclerosis is an inflammatory chronic disease influenced by multiple factors. Different prospective studies have shown that plasmatic levels of inflammatory markers were related to atherosclerosis and cardiovascular disease. OBJECTIVE To evaluate whether plasmatic levels of interleukin 18 (IL-18) are modulated by SNPs (single nucleotide polymorphisms) of the IL 18 gene and its possible association with insulin levels and other cardiovascular risk factors. METHODS 746 individuals were studied for a period of two years by opportunistic selection in the metropolitan area of Valencia. Parameters of lipid and glucose metabolism were analyzed by standard methodology. IL-18 was m…

Normalwerterstellung von Blutströmungsgeschwindigkeiten an der Arteria mesenterica superior bei Früh- und Reifgeborenen mit der Duplexsonographie

1994

In a prospective study blood flow velocity measurements were performed in 110 "healthy" newborn with duplex Doppler sonography in the superior mesenteric artery to obtain standard values. In 49 of these neonates 15, 30, and 45 minutes following feeding examinations were performed. Peak systolic flow velocity, end systolic flow velocity, time average flow velocity and time average maximum flow velocity were determined, the resistance and Pourcelot index as well as the volume blood flow were calculated. The children's gestational age was 27-42 weeks, the postnatal age was 2-68 days and the body weight was 920-4190 g. All measured blood flow velocities showed a synchronous relation to feeding …

Co-morbid mental health conditions in cancer patients at working age - prevalence, risk profiles, and care uptake

2013

Summary Objective This study examined the prevalence of mental health conditions in cancer patients, the role of socioeconomic position in relation to that, and the use of professional mental health care. Methods Prospective cohort with measurements at the beginning of inpatient treatment (baseline) and 3, 9, and 15 months after baseline using structured clinical interviews based on DSM-IV, questionnaires, and medical records. Results At baseline, 149 out of 502 cancer patients (30%) were diagnosed with a mental health condition. Prevalence was associated with unemployment (odds ratio [OR] 2.0), fatigue (OR 1.9), and pain (OR 1.7). Of those with mental health conditions, 9% saw a psychother…

Resection of esophageal diverticulum through uniportal video-assisted thoracoscopic surgery

2018

Open surgery remains the standard strategy for management of esophageal diverticulum in symptomatic patients. However, in the last years an increasing number of minimally invasive approaches have been proposed for this issue in order to reduce the surgical trauma and favor a fast return to daily activity. Herein, we describe a novel technique as uniportal video-assisted thoracoscopic surgery (VATS) for performing resection of esophageal diverticulum. This procedure was successfully carried out in three consecutive patients with giant mid-esophageal diverticulum (mean size: 6.5±0.5 cm). The mean post-operative time was 121±10 minutes. The chest drain was removed 48 hours later in all cases a…

Effect of storage time and donor sex of transfused red blood cells on 1-year survival in patients undergoing cardiac surgery: an observational study

2016

BACKGROUND Red blood cell (RBC) storage lesions and RBCs from females transfused into male recipients may have adverse effects on transfusion recipients' survival. We hypothesized that the effect of donor sex and the effect of age of blood on mortality would be most apparent in cardiac surgery patients. STUDY DESIGN AND METHODS Using data from French Blood Services and two university hospitals, we conducted a retrospective cohort study on cardiac surgery patients whose first transfusion occurred between 2007 and 2011. The age of blood and donor sex effects on 1-year survival were studied using Cox regression modeling, with time-dependent stratification on the number of RBCs and adjustments …
