Alterations of pleiotropic neuropeptide-receptor gene couples in Cetacea.

Background: Habitat transitions have considerable consequences in organism homeostasis, as they require the adjustment of several concurrent physiological compartments to maintain stability and adapt to a changing environment. Within the range of molecules with a crucial role in the regulation of different physiological processes, neuropeptides are key agents. Here, we examined the coding status of several neuropeptides and their receptors with pleiotropic activity in Cetacea.

Isotope-based inferences of the trophic niche of short-finned pilot whales in the Webbnesia.

Knowledge of predator-prey interactions is key in ecological studies and understanding ecosystem function, yet this is still poorly explored in the deep-sea environment. Carbon (δC: C/C) and nitrogen (δN: N/N) stable isotope ratios of a deep-diving species, the short-finned pilot whale (Globicephala macrorhynchus), were used to explore knowledge gaps on its ecological niche and foraging habitats in the Webbnesia marine ecoregion (Tenerife Island, n = 27 animals vs. Madeira, n = 31; 500 km apart) where animals display distinct levels of site fidelity.

Prediction of extracapsular extension of prostate cancer by MRI radiomic signature: a systematic review.

Unlabelled: The objective of this review is to survey radiomics signatures for detecting pathological extracapsular extension (pECE) on magnetic resonance imaging (MRI) in patients with prostate cancer (PCa) who underwent prostatectomy. Scientific Literature databases were used to search studies published from January 2007 to October 2023. All studies related to PCa MRI staging and using radiomics signatures to detect pECE after prostatectomy were included.

Phthalates and fatty acid markers in free-ranging cetaceans from an insular oceanic region: Ecological niches as drivers of contamination.

Plastic additives, such as phthalates, are ubiquitous contaminants that can have detrimental impacts on marine organisms and overall ecosystems' health. Valuable information about the status and resilience of marine ecosystems can be obtained through the monitoring of key indicator species, such as cetaceans. In this study, fatty acid profiles and phthalates were examined in blubber biopsies of free-ranging individuals from two delphinid species (short-finned pilot whale - Globicephala macrorhynchus, n = 45; common bottlenose dolphin - Tursiops truncatus, n = 39) off Madeira Island (NE Atlantic).

Community-Based Action Research Intervention to Promote Occupational Health Nursing of Portuguese Quarry Workers.

The northern region of Portugal has the largest number of companies manufacturing granite and stone products, which has become the region's trademark. In the municipalities of Marco de Canaveses and Penafiel, the economic activity of this area is important. However, the lack of attractiveness of this activity, combined with the high prevalence of silicosis and tuberculosis in this population, has led to a growing shortage of labor.

COVID-19 in Portugal: A Pandemic Redesigned by the Media.

The news media in Portugal played an important role during the COVID-19 pandemic by providing people with important and up-to-date health information. However, the number of news reports did not always correspond to the severity of the pandemic. There was significant media attention at the beginning of the pandemic (in early 2020), but media coverage soon declined, and the Portuguese media began to report on a greater diversity of topics.

Risk Biomarkers for Biochemical Recurrence after Radical Prostatectomy for Prostate Cancer Using Clinical and MRI-Derived Semantic Features.

Objectives: This study aimed to assess the impact of the covariates derived from a predictive model for detecting extracapsular extension on pathology (pECE+) on biochemical recurrence-free survival (BCRFS) within 4 years after robotic-assisted radical prostatectomy (RARP).

Methods: Retrospective data analysis was conducted from a single center between 2015 and 2022. Variables under consideration included prostate-specific antigen (PSA) levels, patient age, prostate volume, MRI semantic features, and Grade Group (GG).

Kaposiform hemangioendothelioma of the thigh: A case report.

Kaposiform hemangioendothelioma is a rare, locally aggressive or borderline vascular tumor that typically affects infants. It presents as a purpuric cutaneous lesion and may be associated with life-threatening coagulation disorders, such as the Kasabach-Merritt phenomenon. The differential diagnosis can be challenging based on clinical presentation alone.

Postural stability computerized evaluation in total knee arthroplasty.

Purpose: To evaluate the balance in patients with total knee arthroplasty (TKA) and knee osteoarthrosis (KOA), measured by postural stability computerized evaluation (PSCE), and to evaluate the effect of post-TKA patients' characteristics in their performance on PSCE.

Materials And Methods: An observational cross-sectional study was conducted in two sets of patients: (A) patients with KOA and primary TKA surgery scheduled and (B) patients who underwent primary TKA >9 months. Sociodemographic, radiographic, clinical and PSCE parameters (using the Biodex Balance System) were assessed.

An incipient development in the field of medical devices takes the form of Smart Health Textiles, which can possess innovative properties such as thermoregulation, sensing, and antibacterial control. This protocol aims to describe the process for the development of a new type of smart clothing for individuals with reduced mobility and/or who are bedridden in order to prevent PIs.

Seeking Brightness in Molecular Erbium-Based Light Upconversion.

Whereas dye-sensitized lanthanide-doped nanoparticles represent an unquestionable advance for pushing linear near-infrared (NIR) to visible-light upconversion within the frame of applications, analogous improvements are difficult to mimic for related but intramolecular processes induced at the molecular level in coordination complexes. Major difficulties arise from the cationic nature of the target cyanine-containing sensitizers (S), which drastically limits their thermodynamic affinities for catching the lanthanide activators (A) required for performing linear light upconversion. In this context, the rare previous design of stable dye-containing molecular SA light-upconverters required large S···A distances at the cost of the operation of only poorly efficient intramolecular S → A energy transfers and global sensitization.

End-User Assessment of an Innovative Clothing-Based Sensor Developed for Pressure Injury Prevention: A Mixed-Method Study.

This study aimed to evaluate a clothing prototype that incorporates sensors for the evaluation of pressure, temperature, and humidity for the prevention of pressure injuries, namely regarding physical and comfort requirements. A mixed-method approach was used with concurrent quantitative and qualitative data triangulation. A structured questionnaire was applied before a focus group of experts to evaluate the sensor prototypes.

Abdominal splenosis mimicking peritoneal carcinomatosis of ovarian cancer.

We present the clinical case of a 53-year-old woman referred for suspicion of recurrence of a mesonephric-like adenocarcinoma of the ovary. Abdominal and pelvic CT revealed multiple round/oval solid nodules with similar density scattered throughout the abdomen and pelvis, the biggest ones appearing in the left hypochondrium; no normal-appearing spleen or ascites were observed. These radiological findings and the absence of significant elevation of CA 125 levels made the radiologists hypothesize that these aspects were related to abdominal splenosis.

Early biomarkers of extracapsular extension of prostate cancer using MRI-derived semantic features.

Background: To construct a model based on magnetic resonance imaging (MRI) features and histological and clinical variables for the prediction of pathology-detected extracapsular extension (pECE) in patients with prostate cancer (PCa).

Methods: We performed a prospective 3 T MRI study comparing the clinical and MRI data on pECE obtained from patients treated using robotic-assisted radical prostatectomy (RARP) at our institution. The covariates under consideration were prostate-specific antigen (PSA) levels, the patient's age, prostate volume, and MRI interpretative features for predicting pECE based on the Prostate Imaging-Reporting and Data System (PI-RADS) version 2.

The imaging features of the main pathologies are described, such as portal thrombosis, Budd-Chiari syndrome, hereditary hemorrhagic telangiectasia, portosystemic shunts and congenital vascular malformations. Endovascular intervention techniques are listed according to the indication for each hepatic vascular pathology and emphasis is placed on the ability to shape disease progression in order to prevent related morbidity and mortality.

Malignant peripheral nerve sheath tumor mimicking an adnexal mass: a radio-pathologic correlation.

We report the case of a pelvic malignant peripheral nerve sheath tumor mimicking an adnexal mass. A 59-year-old postmenopausal woman presented with a 3-month history of diffuse abdominal bloating and urinary frequency. Laboratory tests revealed an increased CA 125.

Effect of pre-conceptional nutrition and season on fetal growth during early pregnancy in sheep.

Gestational age in sheep can be closely predicted through ultrasonographic measurement of fetal bones when correlated to standardized fetal growth curves. However, these standardized curves do not account for factors that are known modulators of fetal growth, such as maternal nutrition or health status. Despite being seasonal breeders, and studies reporting an effect of season on birth weight, the influence of season on fetal growth has not been well characterized.
