A matter of complexity? The role of the dorsal posterior parietal cortex in processing changes in spatial information across time.

The posterior parietal cortex (PPC) is an associative neocortical region that integrates multiple streams of information and is implicated in spatial cognition and decision making. In some cases, however, the PPC is not required for these functions. One possibility is that the PPC is recruited when spatial complexity is high.

Fifteen-year experience of direct bridge with venoarterial extracorporeal membrane oxygenation to heart transplantation.

Objective: The study objective was to evaluate outcomes of patients directly bridged with venoarterial extracorporeal membrane oxygenation to heart transplantation.

Methods: A single-center retrospective study was performed on 1152 adult patients undergoing isolated cardiac transplantation between January 2007 and December 2021. Among these, patients bridged with an extracorporeal membrane oxygenation to transplantation (extracorporeal membrane oxygenation group, n = 317) were compared with standard cohorts of patients (no extracorporeal membrane oxygenation group, n = 835).

A Machine Learning Model Based on MRI Radiomics to Predict Response to Chemoradiation Among Patients with Rectal Cancer.

Background: With rectum-sparing protocols becoming more common for rectal cancer treatment, this study aimed to predict the pathological complete response (pCR) to preoperative chemoradiotherapy (pCRT) in rectal cancer patients using pre-treatment MRI and a radiomics-based machine learning approach.

Methods: We divided MRI-data from 102 patients into a training cohort ( = 72) and a validation cohort ( = 30). In the training cohort, 52 patients were classified as non-responders and 20 as pCR based on histological results from total mesorectal excision.

Lower mini-sternotomy: an approach for treating all valvulopathies?

Background: Lower mini-sternotomy offers the advantage of providing excellent visualization of the 4 cardiac cavities, allowing surgical treatment of aortic, mitral and tricuspid valves as well as any intra-cavitary procedure. Technical issues, as well as safety and echocardiographic results of this approach, are lacking. The aim of this retrospective study was to describe outcomes of lower mini-sternotomy to treat valvulopathies and other intracardiac surgeries.

Approaches to patients with obesity and CKD: focus on nutrition and surgery.

Obesity is recognized as a public health challenge. During the last three decades, the global age-standardized prevalence increased from 8.8% to 18.

Integrating the new pharmacological standard of care with traditional nutritional interventions in non-dialysis CKD.

Chronic kidney disease (CKD) is widely recognized as a leading and growing contributor to global morbidity and mortality worldwide. Nutritional therapy is the basic treatment for metabolic control, and may contribute to nephroprotection; however, the absence of solid evidence on slowing CKD progression together with poor adherence to dietary prescription limit de facto its efficacy and prevent its more widespread use. Sodium-glucose transport protein 2 inhibitors (SGLT2is) are now considered the new standard of care in CKD; in addition, novel potassium binders, glucagon-like peptide-1 receptor antagonists (GLP1-RAs) and nonsteroidal mineralocorticoid receptor antagonists (nsMRAs) show either direct (SGLT2i, GLP1-RA, nsMRA) or indirect (potassium binders that enable the optimal use of renin-angiotensin-aldosterone system inhibitors) nephroprotective effects.

Physical activity and exercise in chronic kidney disease: consensus statements from the Physical Exercise Working Group of the Italian Society of Nephrology.

The Italian Society of Nephrology has tasked its Working Group on Physical Exercise with developing a consensus statement document on physical activity and exercise in patients with chronic kidney disease (CKD). This paper consists of 16 points that were discussed, and approved using the mini-Delphi method by 15 members of the working group. Each statement is based on a comprehensive review of the literature, clinical experience, and expert opinions.

Retinal Reactive Astrocytic Tumor and Astrocytic hamartomas in patient with Neurofibromatosis type 1: Case Report and Literature review.

Introduction: Neurofibromatosis type I, also known as Von Recklinghausen disease, is a common phakomatosis affecting 1 in 2500-3000 live births; it may be associated with several common ocular findings, including Lisch nodules, plexiform neurofibromas, optic pathway gliomas, retinal astrocytic hamartomas and choroidal nodules.

Case Description: This report illustrates clinical evidence of simultaneous presence of retinal reactive astrocytic tumor (RRAT) and two retinal astrocytic hamartomas (RAH) in a 15 y/o patient with NF1, referred to our attention because of an asymptomatic fundus mass in his right eye of recent onset.

Conclusion: This case, in addition to considering NF1 as one of the ocular conditions associated with secondary RRAT, underlines the importance of early referral and continuous ophthalmological follow-up in preventing possible complications that could cause significant visual impairment in patients with NF1.

Influence of haematological parameters on size of the advanced platelet-rich fibrin+ (A-PRF+) in the horse.

The advanced-PRF+ (A-PRF+) is a platelet concentrate, showing a higher concentration of growth factors, an increased number of cells and looser structure of the fibrin clot than leukocyte-PRF. A high variability in the size of PRF associated with patients, haematological features and centrifugation protocols was reported. The aims of this study were to evaluate the feasibility of A-PRF+ production in the field and the correlation between haematological parameters, macroscopic and microscopic features in equine A-PRF+.

Kinematics but not kinetics alterations to single-leg drop jump movements following a subject-tailored fatiguing protocol suggest an increased risk of ACL injury.

Introduction: Neuromuscular fatigue causes a transient reduction of muscle force, and alters the mechanisms of motor control. Whether these alterations increase the risk of anterior cruciate ligament (ACL) injury is still debated. Here we compare the biomechanics of single-leg drop jumps before and after the execution of a fatiguing exercise, evaluating whether this exercise causes biomechanical alterations typically associated with an increased risk of ACL lesion.

It is imperative to comprehend this potential relationship in order to enhance strategies for prevention and treatment.

Infant exposure to drugs of abuse investigated by hair analysis.

Infant exposure to drugs of abuse represents a worldwide problem whose extent is difficult to estimate. Despite the potentially serious health consequences, few data concerning exposure in children under 1 year of age are available. Since in clinical and forensic settings, neonatal and infant hair testing represents a useful method for investigating suspected drug exposures, an observational retrospective study was performed on hair analysis of children under 1 year of age evaluated at the University Hospital of Padova between 2018 and 2022 with the aim of estimate the extent and define the characteristics of this phenomenon in the reference setting.

Comparisons of ammonia- and water-based silver-containing solutions on dentin bonding and enzymatic activity: 1-yr evaluation.

Objective: To evaluate the effects of an ammonia-based and a water-based silver-containing solutions on bonding performance and matrix-metalloproteinases (MMPs) activity of a universal adhesive to dentin after 1 year of artificial aging.

Methods: Mid-coronal dentin surfaces of 60 sound human molars were exposed and the following groups were formed according to the surface pre-treatment and etching mode of the universal adhesive (Zipbond Universal, SDI) (n = 10): G1) Zipbond in the self-etch mode (ZSE); G2) Riva Star (SDI) applied before ZSE; G3) Riva Star Aqua (SDI) applied before ZSE; G4) Zipbond in the etch-and-rinse mode (ZER); G5) Riva Star applied before ZER; G6) Riva Star Aqua applied before ZER. The specimens were sectioned and subjected to microtensile bond strength (µTBS) test at baseline (T) and after 12 months (T) of artificial storage.

Surgical complications after pancreatic transplantation: A computed tomography imaging pictorial review.

Pancreatic transplantation is considered by the American Diabetes Association and the European Association for the Study of Diabetes an acceptable surgical procedure in patients with type 1 diabetes also undergoing kidney transplantation in pre-final or end-stage renal disease if no contraindications are present. Pancreatic transplantation, however, is a complex surgical procedure and may lead to a range of postoperative complications that can significantly impact graft function and patient outcomes. Postoperative computed tomography (CT) is often adopted to evaluate perfusion of the transplanted pancreas, identify complications and as a guide for interventional radiology procedures.

Response to Ustekinumab Therapy Is Associated with an Improvement of Nutritional Status in Patients with Crohn's Disease.
