Hospital work and pregnancy outcomes: a study in the Danish National Birth Cohort
2009
Udgivelsesdato: null-null In hospitals, women of reproductive age do a range of work tasks, some of which are known to carry potential risks. Tasks such as working with radiation, chemicals, and infectious agents, as well as performing heavy lifting or tasks requiring erratic sleep patterns have been reported to increase the risk of reproductive failures. Our aim was to study pregnancy outcomes in female hospital workers in Denmark. We performed a cohort study of 5976 female hospital workers and used as a reference group 60,890 women employed outside of hospitals. The reproductive health of hospital workers working during pregnancy is comparable to those of non-hospital workers for the majo…
Female pelvic congenital malformations. Part I: embryology, anatomy and surgical treatment.
2011
This review covers the most important female congenital pelvic malformations. The first part focuses on the embryological development of the urogenital and anorectal apparatus, morphological features, and the diagnostic and surgical approach to abnormalities. Comprehension of the embryological development of the urogenital and anorectal apparatus is essential to understand the morphology of congenital pelvic abnormalities and their surgical treatment. Congenital pelvic malformations are characterized by specific common features; the severity of which often subverts the pelvic morphology completely and makes it difficult to comprehend before surgery. The development of imaging, mainly magnet…
Gynecological Disorders in Patients with Non-celiac Wheat Sensitivity
2019
Background: Non-celiac wheat sensitivity (NCWS) most frequently presents clinically with irritable bowel syndrome (IBS)-like symptoms, although many extra-intestinal manifestations have also been attributed to it. No studies to date have evaluated the presence and frequency of gynecological symptoms in NCWS. Aim: To evaluate the frequency of gynecological disorders in patients with NCWS. Patients and Methods: Sixty-eight women with NCWS were included in the study. A questionnaire investigating gynecological symptoms and recurrent cystitis was administered, and patients reporting symptoms were then examined by specialists. Three control groups were selected: 52 patients with IBS not related …
Chimney and periscope grafts to facilitate endovascular treatment of aortic transection in a patient with aberrant right subclavian artery
2014
Purpose: To report the use of parallel grafts to extend the proximal landing zone for stentgraft repair of aortic transection involving an aberrant right subclavian artery (ARSA). Case Report: A 28-year-old patient was referred for treatment of traumatic aortic transection with contained rupture at the level of an ARSA. Immediate thoracic endovascular aortic repair (TEVAR) was planned because of hemodynamic instability. To achieve rapid sealing and maintain perfusion to both subclavian arteries, a chimney stent to the left subclavian artery (LSA) and a periscope stent-graft to the ARSA were deployed successfully. After surgical repair of all fractures, the patient was discharged 1 month aft…
No phenotypic differences for polycystic ovary syndrome (PCOS) between women with and without type 1 diabetes mellitus.
2013
Context: Women with type 1 diabetes mellitus (DM1) have a higher prevalence of polycystic ovary syndrome (PCOS) than the general population. Objective: The aim of this study was to clarify, in DM1 women with PCOS(PCOS-DM1), the influence of insulin therapy and glycemic control and evaluate the hormonal and phenotypic differences with age-matched and body mass index (BMI)-matched women with PCOS without diabetes. Design, Setting, and Patients: We evaluated 103 DM1 women with and without PCOS treated with intensive insulin therapy; 38 age-matched and BMI-matched women with PCOS without diabetes were compared in a cross-sectional study. Outcome Measurements: Clinical, anthropometric, and metab…
The role of dispositional and social factors in Argentinian and Spanish women's sexuality
2019
This study examines the role of sociocultural and dispositional factors in the sexual expressions of young Argentinian and Spanish women. Three hundred young women self-evaluated their sexual practices, sexual orientation, and relationships. Results reveal differences in women's sexuality based on societal and dispositional variables. The latter seem to play a more important role in those sexual behaviors that are normative in Hispanic traditions, whereas gender dissimilarity is more relevant when these behaviors are socially censured. Therefore, women's sexuality in Hispanic traditions, such as in Argentina and Spain, seems to be more complex than past studies reported.
Brainstem reflex circuits revisited
2004
Our current understanding of brainstem reflex physiology comes chiefly from the classic anatomical-functional correlation studies that traced the central circuits underlying brainstem reflexes and establishing reflex abnormalities as markers for specific areas of lesion. These studies nevertheless had the disadvantage of deriving from post-mortem findings in only a few patients. We developed a voxel-based model of the human brainstem designed to import and normalize MRIs, select groups of patients with or without a given dysfunction, compare their MRIs statistically, and construct three-plane maps showing the statistical probability of lesion. Using this method, we studied 180 patients with…
Multisensor comparison of NDVI for a semi‐arid environment in Spain
2009
The joint use of multiresolution sensors from different satellites offers many opportunities to describe vegetation and its dynamics. This paper introduces the concept of a virtual constellation (defined as an ensemble of all Earth Observation satellites in orbit that satisfy common requirements) for agricultural applications and contributes to providing the necessary inter-sensor calibration methodology for spectral reflectances and NDVI. For this purpose, we performed an observational study, comparing reflectances and the Normalized Difference Vegetation Index (NDVI), from near-synchronous image pairs of Landsat 7 Enhanced Thematic Mapper Plus (ETM+), as the reference sensor and Landsat 5…
Improved land surface emissivities over agricultural areas using ASTER NDVI
2006
Abstract Land surface emissivity retrieval over agricultural regions is important for energy balance estimations, land cover assessment and other related environmental studies. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) produces images of sufficient spatial resolution (from 15 m to 90 m) to be of use in agricultural studies, in which fields of crops are too small to be well-resolved by low resolution sensors. The ASTER project generates land surface emissivity images as a Standard Product (AST05) using the Temperature/Emissivity Separation (TES) algorithm. However, the TES algorithm is prone to scaling errors in estimating emissivities for surfaces with low s…
Vegetation dynamics from NDVI time series analysis using the wavelet transform
2009
A multi-resolution analysis (MRA) based on the wavelet transform (WT) has been implemented to study NDVI time series. These series, which are non-stationary and present short-term, seasonal and long-term variations, can be decomposed using this MRA as a sum of series associated with different temporal scales. The main focus of the paper is to check the potential of this MRA to capture and describe both intra- and inter-annual changes in the data, i.e., to discuss the ability of the proposed procedure to monitor vegetation dynamics at regional scale. Our approach concentrates on what wavelet analysis can tell us about a NDVI time series. On the one hand, the intra-annual series, linked to th…
