Prospective risk of stillbirth and neonatal complications in twin pregnancies: systematic review and meta-analysis

2016

Twin pregnancies are at increased risk of stillbirth. Uncomplicated twin pregnancies are commonly delivered earlier to prevent stillbirth; however, there is a risk of neonatal complications associated with being born prior to 39 weeks’ gestation. The optimal gestational age for delivery in twin pregnancies is unknown and likely varies by chorionicity. The present study aimed to determine the prospective risk of stillbirth in women with uncomplicated monochorionic and dichorionic twin pregnancies, and neonatal mortality risks, when delivered beyond 34 weeks of gestation. Data on twin pregnancies that reported rates of stillbirth were obtained from MEDLINE, EMBASE, and Cochrane Library. Separ…

Global, regional, and national levels of maternal mortality, 1990–2015: a systematic analysis for the Global Burden of Disease Study 2015

2016

BACKGROUND: In transitioning from the Millennium Development Goal to the Sustainable Development Goal era, it is imperative to comprehensively assess progress toward reducing maternal mortality to identify areas of success, remaining challenges, and frame policy discussions. We aimed to quantify maternal mortality throughout the world by underlying cause and age from 1990 to 2015.METHODS: We estimated maternal mortality at the global, regional, and national levels from 1990 to 2015 for ages 10-54 years by systematically compiling and processing all available data sources from 186 of 195 countries and territories, 11 of which were analysed at the subnational level. We quantified eight underl…

The role of registries in rare genetic lipid disorders: Review and introduction of the first global registry in lipoprotein lipase deficiency

2017

International audience; A good understanding of the natural history of rare genetic lipid disorders is a pre-requisite for successful patient management. Disease registries have been helpful in this regard. Lipoprotein Lipase Deficiency (LPLD) is a rare, autosomal-recessive lipid disorder characterized by severe hypertriglyceridemia and a very high risk for recurrent acute pancreatitis, however, only limited data are available on its natural course. Alipogene tiparvovec (Glybera (R)) is the first gene therapy to receive Marketing Authorization in the European Union; GENIALL (GENetherapy In the MAnagement of Lipoprotein Lipase Deficiency), a 15-year registry focusing on LPLD was launched in …

Quality of Life in Individuals with Diabetic Foot Syndrome.

2020

Background and Objective: Diabetic foot syndrome (DFS) is a common long-term complication of diabetes mellitus. DFS has recently been associated with adverse effects that could further impair the quality of life of diabetic patients, and increase the social and economic burden, morbidity, and premature mortality of the disease. The main physio-pathological basis of DFS is due to diabetesinduced neuropathy and angiopathy in the lower limbs and feet. Patients diagnosed with DFS must significantly modify their daily habits in order to cope with signs and symptoms of DFS and this can alter their quality of life. The objective of this review is to summarize the evidence regarding the economic, …

Dental status, salivary flow, and sociodemographic aspects in Sheehan Syndrome patients

2018

Background Sheehan’s syndrome (SS) is one of the leading causes of hypopituitarism in developing countries. It occurs after postpartum necrosis of the pituitary gland, and it is considered a significant public health problem. This paper, apparently unpublished, aimed to perform an analysis on oral aspects in patients with SS. Material and Methods A cross-sectional study was performed with 23 women diagnosed with SS at the Division of Endocrinology and Diabetes (Walter Cantídio University Hospital, Fortaleza, Brazil). Results Data on sociodemographic, dental and salivary flow aspects were collected through a clinical approach and a panoramic radiograph request. The mean age was 64 ± 11.5 yea…

eIF5A facilitates translation termination globally and promotes the elongation of many non polyproline-specific tripeptide sequences

2017

Abstract eIF5A is an essential protein involved in protein synthesis, cell proliferation and animal development. High eIF5A expression is observed in many tumor types and has been linked to cancer metastasis. Recent studies have shown that eIF5A facilitates the translation elongation of stretches of consecutive prolines. Activated eIF5A binds to the empty E-site of stalled ribosomes, where it is thought to interact with the peptidyl-tRNA situated at the P-site. Here, we report a genome-wide analysis of ribosome stalling in Saccharomyces cerevisiae eIF5A depleted cells using 5Pseq. We confirm that, in the absence of eIF5A, ribosomes stall at proline stretches, and extend previous studies by …

PPAR Agonists, Atherogenic Dyslipidemia and Cardiovascular Risk.

2016

Peroxisome proliferator-activated receptors (PPAR) are implicated in the pathology of several metabolic diseases including obesity, diabetes, and atherosclerosis. PPAR agonists exert multiple lipid modifying actions which are beneficial to the prevention of atherosclerosis. Such benefits in lipid lowering actions include improvements in atherogenic dyslipidemia that seems to be particularly expressed in individuals at higher cardiovascular (CV) risk. In addition, the favorable effects of PPAR agonists on different cardio-metabolic parameters are established in several metabolic conditions, such as diabetes mellitus, insulin resistance, and heightened systemic inflammation. The goal of this …

Pharmacogenomics of Scopoletin in Tumor Cells

2016

Drug resistance and the severe side effects of chemotherapy necessitate the development of novel anticancer drugs. Natural products are a valuable source for drug development. Scopoletin is a coumarin compound, which can be found in several Artemisia species and other plant genera. Microarray-based RNA expression profiling of the NCI cell line panel showed that cellular response of scopoletin did not correlate to the expression of ATP-binding cassette (ABC) transporters as classical drug resistance mechanisms (ABCB1, ABCB5, ABCC1, ABCG2). This was also true for the expression of the oncogene EGFR and the mutational status of the tumor suppressor gene, TP53. However, mutations in the RAS onc…

Stimulation of autophagy prevents intestinal mucosal inflammation and ameliorates murine colitis

2017

Background and pourpose A defective autophagy is involved in the pathogenesis of inflammatory disorders such as IBD. Cross talk interactions between autophagy and inflammation have been reported and we analyse the effects of autophagy stimulators on murine colitis. Experimental approach Mice were treated with intrarectal administration of TNBS (3.5 mg/20 g BW) and body weight was measured every day and histological damage score analysed two or four days after treatment. Some mice received trehalose (3% in drinking water three weeks before TNBS administration) or a daily administration of rapamycin (1.25 mg/kg, i.p.), betanin (1g/kg, i.p.) or betanin + 3MA (10mg/kg, i.p.). Mucosal protein le…

2020

Aims: Current anti-hypertensive therapies cannot cure hypertension and a life-long medication is necessary. Maternal treatment may represent a promising strategy for hypertension treatment. We have previously shown that maternal treatment of spontaneously hypertensive rats (SHR) with pentaerythritol tetranitrate (PETN) leads to a persistent blood pressure reduction in the female offspring at age of 6-8 months. The underlying mechanisms include improved endothelial function resulting from long-lasting epigenetic changes. In the present study, we address the renal effects of maternal PETN treatment. Methods and Results: F0 parental SHR were fed with either normal chow or PETN-containing (1 g/…
