Women's satisfaction and perceived control in childbirth are important attributes of the childbirth experience and quality of care indicators. This article presents findings from the pre-intervention phase of a multi-centre implementation study in Egypt, Lebanon and Syria, to introduce a labour companionship model in these countries. A sample of 2620 women giving birth in three public teaching hospitals from November 2014 to July 2015 in Beirut and Mansoura, and from November 2014 to April 2015 in Damascus were interviewed by trained field workers...

An efficient scheme for the calculation of Born-Oppenheimer molecular dynamics (BOMD) simulations is introduced. It combines the corrected small basis set Hartree-Fock (HF-3c) method by Sure and Grimme [J. Comput. Chem. 2013, 43, 1672], extended Lagrangian BOMD (XL-BOMD) by Niklasson et al. [J. Chem. Phys. 2009, 130, 214109], and the calculation of the two electron integrals on graphics processing units (GPUs) [J. Chem. Phys. 2013, 138, 134114; J. Chem. Theory Comput. 2015, 11, 918]. To explore the parallel performance of our strong scaling implementation of the method, we present timings and extract, as its validation and first illustrative application, high-quality vibrational spectra from simulated trajectories of β-carotene, paclitaxel, and liquid water (up to 500 atoms)...

Cellular transformation owing to cigarette smoking is due to chronic exposure and not acute. However, systematic studies to understand the molecular alterations in lung cells due to cigarette smoke are lacking. To understand these molecular alterations induced by chronic cigarette smoke exposure, we carried out tandem mass tag (TMT) based temporal proteomic profiling of lung cells exposed to cigarette smoke upto 12months. We identified 2620 proteins in total, of which 671 proteins were differentially expressed (1...

AIM: To assess the use of serum levels of angiopoietin-1 (Ang1), Ang2 and tumor necrosis factor-α (TNFα) as predictive factors for small bowel angiodysplasia (SBA). METHODS: Serum samples were collected from patients undergoing capsule endoscopy for any cause of obscure gastrointestinal bleeding (OGIB) or anaemia. Based on small bowel findings patients were divided into 3 groups: (1) SBA; (2) other bleeding causes; and (3) normal, according to diagnosis. Using ELISA technique we measured serum levels of Ang1, Ang2 and TNFα and compared mean and median levels between the groups based on small bowel diagnosis...

Flavin-containing monooxygenase 3 (FMO3) plays a critical role in catalyzing the conversion of trimethylamine (TMA) to trimethylamine-N-oxide (TMAO) in vivo. Despite the well-documented association between FMO3 mutations and a 'fishy' off-flavor eggs in chicken and quail, little information is available regarding the molecular characteristic of goose (Anser cygnoides) FMO3 and its relationship with the yolk TMA content. To fill these gaps, we cloned the full-length cDNA sequence of goose FMO3, which comprised 1851bp encoding 531 amino acids...

Canine oocytes ovulated at prophase complete meiosis and continue to develop in presence of a high progesterone concentration in the oviduct. Considering that meiotic competence of canine oocyte is accomplished in the oviductal environment, we postulate that hormonal milieu resulting from the circulating progesterone concentration may affect oocyte maturation and early development of embryos. From 237 oocyte donors, 2620 oocytes were collected and their meiotic status and morphology were determined. To determine optimal characteristics of the mature oocytes subjected to nuclear transfer, a proportion of the meiotic status of the oocytes were classified in reference to time post-ovulation as well as progesterone (P4) level...

BACKGROUND: Accessory ossicles off the talus (os trigonum) are a common radiographic finding seen within the foot with variable symptomatology in adult and pediatric patients. Although most studies have examined the incidence of these anatomic variants in a retrospective manner, few have longitudinally followed the behavior of os trigonum over time. The aim of this study was to investigate the incidence, mean age of appearance and fusion, and fusion rate of os trigonum in a large cohort of asymptomatic pediatric patients...

BACKGROUND: Despite widespread utilization of influenza vaccines, effectiveness (VE) has not been routinely measured in Latin America. METHODS: We used a case test-negative control design to estimate trivalent inactivated influenza VE against laboratory-confirmed influenza among hospitalized children aged 6months-5years and adults aged ≥60years which are age-groups targeted for vaccination. We sought persons with severe acute respiratory infections (SARI), hospitalized at 71 sentinel hospitals in Argentina, Brazil, Chile, Colombia, Costa Rica, El Salvador, Honduras, Panama, and Paraguay during January-December 2013...

Productivity of conifers in seasonally snow-covered forests is high before and during snowmelt when environmental conditions are optimal for photosynthesis. Climate change is altering the timing of spring in many locations, and changes in the date of transition from winter dormancy can have large impacts on annual productivity. Sap flow methods provide a promising approach to monitor tree activity during the cold season and the winter-spring and fall-winter transitions. Although sap flow techniques have been widely used, cold season results are generally not reported...

It remains inconclusive whether hyperuricemia is a true risk factor for kidney graft failure. In the current study, we investigated the association of hyperuricemia and graft outcome. We performed a multi-center cohort study that included 2620 kidney transplant recipients. The patients were classified as either normouricemic or hyperuricemic at 3 months after transplantation. Hyperuricemia was defined as a serum uric acid level ≥ 7.0 mg/dL in males or ≥ 6.0 mg/dL in females or based on the use of urate-lowering medications...

BACKGROUND: Weight gain during chemotherapy in women with breast cancer is commonly reported. However, there are important differences between studies that examined weight change during chemotherapy; e.g. type of chemotherapy, menopausal status, time between body weight measurements and sample size. The purpose of this meta-analysis was to quantify changes in body weight during chemotherapy for women with breast cancer, taking these differences into account. METHODS: We identified relevant studies using PubMed, Scopus and Embase databases...

In order to evaluate the zoonotic risk due to Babesia spp., especially B. microti, we investigated their presence in 597 individuals of five small mammal species and in 2620 questing nymphs of Ixodes ricinus in rural landscapes of Western France (Brittany). Small mammals (rodents and shrews) are indeed suspected to be reservoir hosts for B. microti, and the tick I. ricinus is the vector of the three main zoonotic species in Europe, i.e. B. divergens, B. venatorum and B. microti. Only one bank vole carried B...

The impact of second-generation drug-eluting stent (G2-DES) implantations compared with first-generation drug-eluting stents (G1-DES) implantations on long-term clinical outcomes after percutaneous coronary intervention in patients with and without diabetes mellitus (DM) has not yet been adequately assessed. This pooled analysis compared 3-year clinical outcomes between G1- and G2-DES according to the presence or absence of DM, using individual patient-level data from the RESET and NEXT trials. Among 6431 patients, G1-DES and G2-DES were used in 713 and 2211 patients, respectively, in the DM stratum, and 887 and 2620 patients, respectively, in the non-DM stratum...

Cystic fibrosis (CF) occurrence in Arab populations is not common and still remains underidentified. Furthermore, the lack of disease awareness and diagnosis facilities have mislead the identification of cystic fibrosis for decades. The knowledge about cystic fibrosis (CF) in Egypt is very limited, and a few reports have drawn attention to the existence of CF or CFTR-related disorders (CFTR-RDs) in the Egyptian population. Therefore a comprehensive genetic analysis of the CFTR gene was realized in patients of North Egypt...

Previous investigations have shown that changes in total prostate volume (TPV) are highly variable among aging men, and a considerable proportion of aging men have a stable or decreasing prostate size. Although there is an abundance of literature describing prostatic enlargement in association with benign prostatic hyperplasia, less is known about the appropriate age cut-off points for TPV growth rate. In this community-based cohort study, TPV was examined once a year in men who had consecutive health checkup, during a follow-up of 4 years...
