Ovulation induction and epigenetic anomalies

2013

In this systematic review of ovulation induction and epigenetic control, studies mainly done in the mouse model highlight how hormone treatments may be prejudicial to the epigenetic reprogramming of gametes as well as early embryos. Moreover, the hormone protocols used in assisted reproduction may also modify the physiologic environment of the uterus, a potential link to endometrial epigenetic disturbances. At present, the few available data in humans are insufficient to allow us to independently determine the impact of a woman's age and infertility problems and treatment protocols and hormone doses on such processes as genomic imprinting.

Obesity and assisted reproductive technology outcomes.

2006

Obesity is a rising health problem in Western societies. It has been related to increased morbidity and mortality rates due to several pathologies. In the field of gynaecology and reproduction, obesity is associated with menstrual disorders, hirsutism, infertility, miscarriage and obstetric complications. It is known to impair human reproduction through different mechanisms such as insulin resistance, hyperandrogenism and elevated leptin levels. Weight management and dietary intervention can reverse this situation and improve reproductive function. Obesity can also impair the outcome of assisted reproductive technologies. The lower probability of a healthy live birth described in obese wome…

Computer assisted language learning and the internationalisation of the Portuguese language in higher education contexts

2015

The internationalisation of the Portuguese language has become a priority for academic institutions of different Portuguese-speaking countries which are trying to adapt to the current context of globalisation and ubiquitous communications through digital media. In order to achieve it, several challenges should be faced, namely providing international students with resources aimed at helping them improve their Portuguese while fostering its use in academic and scientific contexts. This can be done by identifying, creating and editing high-quality teaching materials which bear in mind the sociocultural, political, economic and linguistic contexts; using the Information and Communication Techn…

IoT-Based Home Monitoring: Supporting Practitioners' Assessment by Behavioral Analysis.

2019

This paper introduces technical solutions devised to support the Deployment Site - Regione Emilia Romagna (DS-RER) of the ACTIVAGE project. The ACTIVAGE project aims at promoting IoT (Internet of Things)-based solutions for Active and Healthy ageing. DS-RER focuses on improving continuity of care for older adults (65+) suffering from aftereffects of a stroke event. A Wireless Sensor Kit based on Wi-Fi connectivity was suitably engineered and realized to monitor behavioral aspects, possibly relevant to health and wellbeing assessment. This includes bed/rests patterns, toilet usage, room presence and many others. Besides hardware design and validation, cloud-based analytics services are intro…

Fast and green: Sustainable rapid-prototyping of microfluidic chips on polylactic acid substrates

2018

This paper reports novel ways to bond bio-based polylactic acid (PLA) substrates for the production of sustainable, single-use, microfluidic components. A laser-based, fast (minutes) fabrication process for multi-layer microfluidic devices in PLA was reported recently but in that report, demonstrator devices were bonded with adhesive tape, which significantly reduced the devices transparency. In this paper, we propose two novel ways to bond PLA substrates, which alleviate the need for adhesives, and enable optimal device transparency.

P111 ROBOTIC-ASSISTED REPAIR OF IATROGENIC LEFT BRONCHUS PERFORATION DURING RAMIE – A CASE REPORT

2019

Abstract Background Iatrogenic bronchial injury during an esophageal surgery is a severe complication. Hence, immediate treatment is necessary to avoid further pulmonary complications and death. We present a case of an intraoperative bronchial injury caused by a bronchial tube cuff during a full robotic-assisted Ivor-Lewis esophagectomy (RAMIE). Case report A 64-year old patient with adenocarcinoma of the distal esophagus was planned for a RAMIE after completing neoadjuvant radiochemotherapy. Before beginning the thoracic phase, the anesthesist reported an airway leakage during the ventilation. During the transthoracic robotic assisted esophagectomy a perforation of the left main bronchus c…

Photo-assisted formation of a chelating diphos ligand from PPh3 and a cyclometallated [P(C6H4)(C6H5)2]− ligand. Crystal structure of Pd{η2-o-[P(C6H5)…

2000

Abstract The cyclometallated palladium compound, Pd[η2-(C6H4)P(C6H5)2]Br[P(C6H5)3] (1), in the solid state by action of light, evolves to give Pd{η2-o-[P(C6H5)2]2(C6H4)}Br2 (2). This compound contains the diphosphine, o-[P(C6H5)2]2(C6H4), as chelated ligand that is formed by a couple reaction of the metallated ligand η2-[(C6H4)P(C6H5)2]− and the coordinated arylphosphine. A study by NMR spectroscopy confirms that the o-phenylene bridge in the diphosphine ligand in 2 comes from the metallated phosphine ligand in 1.

Prevalence of pathogenic copy number variants among children conceived by donor oocyte.

2021

AbstractDevelopment of assisted reproductive technologies to address infertility has favored the birth of many children in the last years. The majority of children born with these treatments are healthy, but some concerns remain on the safety of these medical procedures. We have retrospectively analyzed both the fertilization method and the microarray results in all those children born between 2010 and 2019 with multiple congenital anomalies, developmental delay and/or autistic spectrum disorder (n = 486) referred for array study in our center. This analysis showed a significant excess of pathogenic copy number variants among those patients conceived after in vitro fertilization with donor …

SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study

2021

Abstract Background Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18–49, 50–69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results NNVs were more favourable in su…
