Programmable liquid handling devices for cell culture systems have dramatically enhanced scalability and reproducibility. We previously reported a protocol to produce cell aggregates demonstrating growth plate-like structures containing hypertrophic chondrocytes from human induced pluripotent stem cells (hiPSCs). To apply this protocol to large-scale drug screening for growth plate-related diseases, we adapted it to the automated cell culture system (ACCS) consisting of programmable liquid handling devices connected to CO2 incubators, a refrigerator, and labware feeders, designed for up to 4 batches with several cell culture plates culturing for several months...

Chondrodysplasias are hereditary diseases caused by mutations in the components of growth cartilage. Although the unfolded protein response (UPR) has been identified as a key disease mechanism in mouse models, no suitable in vitro system has been reported to analyze the pathology in humans. Here, we developed a three-dimensional culture protocol to differentiate hypertrophic chondrocytes from induced pluripotent stem cells (iPSCs) and examine the phenotype caused by MATN3 and COL10A1 mutations. Intracellular MATN3 or COL10 retention resulted in increased ER stress markers and ER size in most mutants, but activation of the UPR was dependent on the mutation...

Earlier data suggest a relationship between PIBF concentrations and the outcome of pregnancy. The aim of the study was to compare serum and urine concentrations of PIBF in women with successful pregnancy after IVF with those of women without pregnancy after IVF procedure, and to evaluate the potential relation between PIBF and the outcome of pregnancy. Urine and serum were collected from 120 women, undergoing IVF. 87.5% of patients had primary infertility. 69.2% faced female causes of infertility: 10.8% tubal cause, 11...

An increasing number of patients with central nervous system (CNS) tumour could survive to reproductive age. However, it is largely unknown whether the history of CNS tumour might affect pregnancy outcome. We aimed to explore the risk of being born pretem among children of CNS tumour survivors. By linking several nationwide registers in Sweden, we identified 1369 children whose parents were childhood or adolescent CNS tumour survivors. Children whose parents did not have CNS tumour were matched randomly with a 5:1 ratio to generate the reference group...

BACKGROUND: Late-preterm infants show lower breastfeeding rates when compared with term infants. Current practice is to keep them in low-risk wards where clinical guidelines to support breastfeeding are well established for term infants but can be insufficient for late-preterm. OBJECTIVE: The aim of this study was to evaluate an intervention supporting breastfeeding among late-preterm infants in a maternity service in the Basque Country, Spain. METHODS: The intervention was designed to promote parents' education and involvement, provide a multidisciplinary approach and decision-making, and avoid separation of the mother-infant dyad...

OBJECTIVE: To improve rate of skin-to-skin contact for early initiation of breastfeeding at birth on operation table among healthy term and late pretem babies born by caesarean sections from 0% to 80% in eight weeks. METHODS: A quality improvement initiative was undertaken at maternity-newborn care unit of a tertiary-care hospital. A team involving Neonatologists/Pediatricians, Obstetricians, Anaesthesiologists, and Nurses in concerned areas identified problem areas using Fish bone analysis...

Hospitalized cancer patients are at high risk of venous thromboembolism (VTE). Despite current recommendations in clinical guidelines, thromboprophylaxis with low molecular weight heparin (LMWH) is underused. We performed an observational prospective study to analyse factors influencing prophylaxis use, VTE events and mortality in cancer-hospitalized patients. 1072 consecutive adult cancer patients were included in an University Hospital from April 2014 to February 2017, and followed-up for 30 days after discharge...

BACKGROUND AND OBJECTIVES: There are a lot of venous thromboembolism risk assessment models with the aim of predicting the individual risk of venous thromboembolism (VTE), although most have not been externally validated. The objective of our study was to analyse the concordance among the Padua, PRETEMED, IMPROVE and MEDENOX scores. PATIENTS AND METHODS: Observational cohort study with 602 patients admitted to Medical Services of the Hospital Universitario Santa Lucía...

OBJECTIVES: To determine the measures to prevent spontaneous preterm birth (excluding preterm premature rupture of membranes)and its consequences. MATERIALS AND METHODS: The PubMed database, the Cochrane Library and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. RESULTS: In France, premature birth concerns 60,000 neonates every year (7.4 %), half of them are delivered after spontaneous onset of labor...

OBJECTIVES: The safety of paternal use of anti-tumor necrosis factor-α (TNF-α) agents immediately prior to conception is practically unknown. On the basis of nationwide data from Danish health registries, we examined the association between paternal use of anti-TNF-α agents within 3 months before conception and adverse birth outcomes. METHODS: This nationwide cohort study is based on data from all women who had a live born singleton child in Denmark from 1 January 2007 through 2013...

UNLABELLED: The aim was to assess the incidence of complications related to skin-to-skin contact (SSC) in newborns with an umbilical venous catheter (UVC). We carried out a prospective follow-up study of all UVCs in a level 3 unit where SSC is systematic. A total of 333 babies were included (mean gestational age of 31.3 weeks (24-41), mean birth weight of 1618 g (454-4900). Two hundred sixty-three babies (78.9 %) had SSC, at a mean postnatal age of 24 h (3-144 h). Two babies presented with a significant umbilical bleeding, all in the first 3 h, before SSC...

BACKGROUND AND OBJECTIVES: Hospitalized patients are a population at risk for venous thromboembolism (VTE). The PRETEMED-2007 clinical practice guidelines help identify high-risk medical patients who are suited to thromboprophylaxis. These guidelines therefore provide a standard for prophylaxis in such patients. We evaluated the risk of VTE and the adjustment of thromboprophylaxis to the standards of the PRETEMED-2007 guidelines in patients hospitalized in internal medicine departments...

OBJECTIVE: To analyze the incidence of VTE in hospitalized medical patients and prophylaxis applied in accordance with the 8th ACCP guidelines and the National PRETEMED guide for thromboprophylaxis. METHODS: Discharge lists were reviewed to select the first consecutive 20 patients, aged ≥ 40 years and admitted ≥ 4 days to the Internal Medicine Departments of 79 Spanish hospitals. Exclusion criteria were: admission for diagnostic procedures, VTE or surgical illness, or care during hospitalization provided by the local investigator...

INTRODUCTION: The study aims to determine the percentage of patients treated at home with an indication of prophylaxis of thromboembolic disease (TED) according to the PRETEMED guidelines and whether they receive such prophylaxis. MATERIALS AND METHODS: A cross-sectional descriptive study was conducted in Segovia Palace Health Centre (Madrid). INCLUSION CRITERIA: to be included in the domiciliary care protocol. EXCLUSION CRITERIA: terminal patient, hospitalised or surgery in the last 3 months...

BACKGROUND AND OBJECTIVE: The aim of this study is to evaluate the use of venous thromboembolism prophylaxis in hospitalized medical patients using 2 clinical practice guidelines and to analyze the agreement between them. PATIENTS AND METHODS: Cross-sectional study of medical services in a third level hospital.

OBJECTIVE: To investigate calcium, iron and magnesium intakes of preterm infants' mothers before and during pregnancy and calcium, iron and magnesium levels of preterm infants and their mothers in order to provide basis for studying the effect of nutritional factors on the occurrence of prematurity. METHODS: Two hundred and forty matched cases (preterm infants and their mothers) and controls (term infants and their mothers) were recruited. A nutritional survey of calcium, iron and magnesium intakes was performed in the mothers before and during pregnancy...

OBJECTIVES: Newborns, particularly preterm infants, have limited antioxidant protective capacity. The organism's defence system against reactive oxygen species including vitamins A, E and C, trace element selenium (Se) and enzymes, such as catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) are essential components of the antioxidant system against the oxidative injury to the cellular membranes of erythrocytes. In this study, our aim was to compare the oxidant nitric oxide (total plasma nitrite level as an indicator of nitric oxide (NO)), antioxidant vitamins and selenium and erythrocyte antioxidant enzymes in premature babies with hyperbilirubinaemia with healthy preterms...

Twenty-one preterm infants (with a mean gestational age and birth weight of 29.3 weeks and 1288.6 g) and nine pretem infants (with a mean gestational age and birth weight of 29.6 weeks and 1153.1 g) were treated with an enteral preparation of indomethacin and with intravenous indomethacin, respectively, for the closure of hemodynamically significant ductus arteriosus. The patients received three doses of either oral indomethacin capsule (Endol, Deva, Turkey) or intravenous indomethacin (Confortid, Dumex GmBH, Germany) in a dose of 0...
