Is Joint Aspiration to Rule Out Prosthetic Joint Infection Required Before ever...
Diniz, Sara Elisa; Vinha, André; Ribau, Ana; Soares, Daniel; Araújo Abreu, Miguel; Sousa, Ricardo; Diniz, Sara ElisaIntroduction: Synovial fluid investigation is the best alternative to diagnose prosthetic joint infection (PJI) before ade‐ quate microbiological/histology sampling during revision surgery. Although accurate preoperative diagnosis is certainly recommended, puncturing every patient before revision arthroplasty raises concerns about safety and feasibility issues especially in difficult to access joint (e.g., hip)...
Advantages of a MultidisciplinaryTeam in the Treatment of Boneand Joint Infections
Sousa, Ricardo; Araújo Abreu, MiguelBone and joint infections represent a significant source of morbidity and mortality, often termed a “silent epidemic.” While native infections, such as septic arthritis and osteomyelitis, still persist, surgical site infections related to orthopedic implants have gained particular prominence due to their growing prevalence and complexity. These infections not only lead to substantial patient morbidity and morta...
Manufacturing of novel cork-STF composites designed for impact energy absorption
Sousa, Guilherme; Fernandes, Fábio; Rocha, Ana; Serra, Gabriel; Sousa, RicardoShear thickening fluids (STF) viscosity significantly increases when subjected to an external dynamic load. Recent advances show their potential for engineering applications, such as developing shock absorbers and impact energy-absorbing structures. There is a search for sustainable materials for several applications due to the critical need to replace nonrenewable raw materials. Cork is a sustainable material ...
Muscle Mass Evaluation and Nutritional Support in the Critically Ill Patient
Mano, Diana; Vidal, César; de Mendonça, Teresa; Sousa, Ricardo; Santos, Mariana; Pinho, João Pedro; Marinho, Ricardo; Marinho, AníbalIntroduction: The loss of muscle mass is becoming a very common problem among critically ill patients and it’s also strongly related to their prognosis and quality of life after leaving the intensive care unit. The purpose of this study was to evaluate the loss of muscle mass in the first five days, since the patient is admitted to the intensive care unit, and if there is a relationship between this muscle wast...
Inflammation of BCG Inoculation Site Scar after the First Dose of an Anti-SARS-...
Barros Rodrigues, João; Pacheco, Maria; Antunes, Ivan; Sousa, RicardoInflammatory reactions in the Bacillus Calmette-Guérin (BCG) inoculation scar site have been previously described, in association with viral infections. The inflammation of the scar in association with other vaccines has been described with the flu vaccine and, more recently, after the second dose of mRNA anti-SARS-CoV-2 vaccines (mRNA-1273 e BNT162b2), in two healthcare workers. We present the case of a 27-yea...
Cross-leg flap after postraumatic osteomyelitis defect: A last resource for lim...
Campos Pereira, Eva; Diniz, Sara; Rodrigues, Filipe; Pereira, Alexandre; Sousa, RicardoWe report the case of a patient with a tibial shaft fracture occurring through a chronic posttraumatic osteomyelitis site with significant soft tissue defect. The bone and soft tissue reconstruction procedures are described with a cross-leg fasciocutaneous flap performed as a last resource after previous rotated muscle flap partial failure. Pre-operative CT angiography, to rule outaxial vessel damage and periph...
Adult Native Joint Septic Arthritis: A Nine-Year Retrospective Analysis in a Po...
Cipriano, Ana; Santos, Fábio Videira; Dias, Rita; Carvalho, André; Reis, Ernestina; Pereira, Claudia; Santos, Ana Cláudia; Sousa, RicardoIntroduction: Septic arthritis of a native joint represents a medical emergency. Drainage and effective antibiotic treatment are critical to avoid joint destruction and long-term impairment. The aim of this study was to evaluate epidemiological and clinical characteristics of patients with the diagnosis of septic arthritis to help establish local guidelines for empirical antibiotic treatment.Material and Method...
Pleistocene expansion, anthropogenic pressure and ocean currents: Disentangling...
Sousa, Ricardo; Vasconcelos, Joana; Vera-Escalona, Iván; Pinto, Ana Rita; Hawkins, S. J.; Freitas, Mafalda; Delgado, João; González, José A.Aims: Rising sea-level following the Last Glacial Maximum lead to fragmentation of coastal limpet populations between islands of the Archipelago of Madeira. This fragmentation is reinforced by recent heavy exploitation reducing effective population size on Madeira Island. We use the limpet P. aspera to understand how the role of processes at different time scales (i.e. changes in the sea level and overexploitat...
The shell phenotypic variability of the keyhole limpet Fissurella latimarginata...
Vasconcelos, Joana; Caamaño, Diego; Tuset, Víctor M.; Sousa, Ricardo; Riera, RodrigoHydrodynamics are a major environmental factor on intertidal rocky shores. Morphological responses to this factor are expected to strongly influence spatial distribution of species across environmental gradients. We here analysed the shell phenotypic variability of the limpet Fissurella latimarginata using geometric mor phometric analysis. The limpets were obtained from a sheltered intertidal coastal area and a...
Major ocean currents may shape the microbiome of the topshell Phorcus sauciatus...
Sousa, Ricardo; Vasconcelos, Joana; Vera-Escalona, Iván; Delgado, João; Freitas, Mafalda; González, José A.; Riera, RodrigoStudies on microbial communities are pivotal to understand the role and the evolutionary paths of the host and their associated microorganisms in the ecosystems. Meta-genomics techniques have proven to be one of the most efective tools in the identifcation of endosymbiotic communities of host species. The microbiome of the highly exploited topshell Phorcus sauciatus was characterized in the Northeastern Atlanti...
