Association between multimorbidity and postoperative mortality in patients undergoing major surgery: a prospective study in 29 countries across Europe

STARSurg Collaborative, EuroSurg Collaborative, S. K. Kamarajah, O. Kouli, more

Background Multimorbidity poses a global challenge to healthcare delivery. This study aimed to describe the prevalence of multimorbidity, common disease combinations and outcomes in a contemporary cohort of patients undergoing major abdominal surgery. Methods This was a pre‐planned analysis of a prospective, multicentre, international study investigating cardiovascular complications after major...

Impact of postoperative cardiovascular complications on 30‐day mortality after major abdominal surgery: an international prospective cohort study

STARSurg Collaborative, the EuroSurg Collaborative, O Kouli, D Chaudhry, more

Anaesthesia > 79 > 7 > 715 - 724

Cardiovascular complications after major surgery are associated with increases in morbidity and mortality. There is confusion over definitions of cardiac injury or complications, and variability in the assessment and management of patients. This international prospective cohort study aimed to define the incidence and timing of these complications and to investigate their impact on 30‐day all‐cause...

Model‐based risk analysis for system design

J. Pedro Mendes

Systems Engineering > 27 > 1 > 5 - 20

Despite being the dominant risk analysis paradigm, event guessing is useless for systems design. In management, no event guessing has ever preempted the launch of policies that are decided, not designed. In engineering, events are not guessed; rather, they are created for testing purposes. Events provide inputs to which systems respond according to their structure, as described by state‐space or equivalent...

The impact of surgical delay on resectability of colorectal cancer: An international prospective cohort study

COVIDSurg Collaborative, Michel Adamina, Adesoji Ademuyiwa, Adewale Adisa, more

Colorectal Disease > 24 > 6 > 708 - 726

Aim The SARS‐CoV‐2 pandemic has provided a unique opportunity to explore the impact of surgical delays on cancer resectability. This study aimed to compare resectability for colorectal cancer patients undergoing delayed versus non‐delayed surgery. Methods This was an international prospective cohort study of consecutive colorectal cancer patients with a decision for curative surgery (January–April...

Seroprevalence of anti‐SARS‐CoV‐2 antibodies in COVID‐19 patients and healthy volunteers up to 6 months post disease onset

Patrícia Figueiredo‐Campos, Birte Blankenhaus, Catarina Mota, Andreia Gomes, more

European Journal of Immunology > 50 > 12 > 2025 - 2040

SARS‐CoV‐2 has emerged as a human pathogen, causing clinical signs, from fever to pneumonia—COVID‐19—but may remain mild or asymptomatic. To understand the continuing spread of the virus, to detect those who are and were infected, and to follow the immune response longitudinally, reliable and robust assays for SARS‐CoV‐2 detection and immunological monitoring are needed. We quantified IgM, IgG, and...

Aging effects in public policy making

J. Pedro Mendes, Miguel Aleluia

System Dynamics Review > 35 > 3 > 232 - 254

Administrations in public education can do little besides struggle to balance the number of needed and available teachers. Conventional student–teacher ratios perpetuate trends and are unfit for policy making. Besides lacking a suitable alternative, the Portuguese government was concerned that declining birth rates might make tenured teachers redundant over time. Their hiring policies became gradually...

⁸⁷Sr/⁸⁶Sr applied to age discrimination of the Palaeozoic carbonates of the Ossa-Morena zone (SW Iberia Variscides)

N. Moreira, J. Pedro, J. F. Santos, A. Araújo, more

International Journal of Earth Sciences > 2019 > 108 > 3 > 963-987

Four distinct Palaeozoic episodes of marine carbonate sedimentation are reported in the Ossa-Morena Zone (SW Iberian Variscides). Among them, the Cambrian and the Devonian episodes are those that are well represented in the Portuguese domains of the Ossa-Morena zone. In this zone, the strong Variscan deformation and metamorphic recrystallization obliterate the biostratigraphic contents of some carbonate...

Temporal variability and time compression of sediment yield in small Mediterranean catchments: impacts for land and water management

A. Smetanová, Y. Le Bissonnais, D. Raclot, J. Pedro Nunes, more

Soil Use and Management > 34 > 3 > 388 - 403

Increased soil erosion, pressure on agricultural land, and climate change highlight the need for new management methods to mitigate soil loss. Management strategies should utilize comparable data sets of long‐term soil erosion monitoring across multiple environments. Adaptive soil erosion management in regions with intense precipitation requires an understanding of inter‐annual variability in sediment...

Insulin resistance and sex hormone‐binding globulin are independently correlated with low free testosterone levels in obese males

P. Souteiro, S. Belo, S. C. Oliveira, J. S. Neves, more

Andrologia > 50 > 7 > n/a - n/a

Male obesity is associated with decreased testosterone levels but the pathophysiological mechanisms behind this association are not completely understood. This study aimed to investigate the impact of hyperglycaemia/insulin resistance and sex hormone‐binding globulin (SHBG) levels on testosterone levels in a population of obese men. We investigated the impact of several clinical, anthropometric and...

Music-supported therapy in the rehabilitation of subacute stroke patients: A randomized controlled trial

J. Grau-Sánchez, E. Duarte, N. Ramos-Escobar, J. Sierpowska, more

Annals of Physical and Rehabilitation Medicine > 2018 > 61 > S > e191

Music-supported therapy (MST) has been developed as a tool in neurorehabilitation to restore hemiparesis of the upper extremity after a stroke based on the ability of music training to promote brain plasticity. However, the effects of MST have not been appropriately contrasted with conventional therapy. The aim of this trial was to test the effectiveness of adding MST to a standard rehabilitation...

Morphological changes of the internal carotid artery: prevalence and characteristics. A clinical and ultrasonographic study in a series of 19 804 patients over 25 years old

H. F. G. Martins, A. Mayer, P. Batista, F. Soares, more

European Journal of Neurology > 25 > 1 > 171 - 177

Background and purpose Morphological changes of the internal carotid arteries (McICA) are frequently found during cervical ultrasound studies. However, the etiology of McICA remains controversial. During this study, the prevalence and demographic characteristics of McICA, such as kinking, coiling or looping identified by Doppler ultrasound, were analysed and its relationship with vascular risk factors...

GLUT1‐mediated glucose uptake plays a crucial role during Plasmodium hepatic infection

Patrícia Meireles, Joana Sales‐Dias, Carolina M. Andrade, João Mello‐Vieira, more

Cellular Microbiology > 19 > 2 > n/a - n/a

Intracellular pathogens have evolved mechanisms to ensure their survival and development inside their host cells. Here, we show that glucose is a pivotal modulator of hepatic infection by the rodent malaria parasite Plasmodium berghei and that glucose uptake via the GLUT1 transporter is specifically enhanced in P. berghei‐infected cells. We further show that ATP levels of cells containing developing...

2017 IEEE 5th Portuguese Meeting on Bioengineering (ENBENG)

Diabetes mellitus (DM) is a group of diseases characterized by chronic hyperglycemia caused by inadequate insulin secretion or impaired insulin action, or both. Diabetic corneal neuropathy can result in chronic, sight-threatening corneal pathology. In vivo non-invasive techniques to determine the changes in corneal thickness are of extreme importance to adequately monitor disease progression. In this...

2017 IEEE 5th Portuguese Meeting on Bioengineering (ENBENG) > 1 - 4

2017 IEEE 5th Portuguese Meeting on Bioengineering (ENBENG)

An increasing number of commercial and scientific solutions for unmanned vehicles, aeronautical/aerospace navigation systems, health and sports monitoring solutions, has been prompted by the development of Micro-Electro-Mechanical Systems based inertial sensors. These sensors, with small form factor and low cost, present an advantage for computing three-dimensional space object orientation. Also radio...
