Brain functional connectivity is altered in patients with Takotsubo Syndrome.

Takotsubo syndrome (TTS) is an acute, reversible cardiomyopathy. The central autonomic nervous system (ANS) is believed to play a role in this disease. The aim of the present study was to investigate the patterns of brain functional connectivity in a sample of patients who had experienced a previous episode of TTS.

Triple POCUS: A New Approach to an Old Problem.

Unlabelled: Pulmonary embolism (PE) is the most serious and life-threatening clinical presentation of venous thromboembolism, and difficult to diagnose. Triple point-of-care-ultrasonography (POCUS) of the lung, heart and leg veins is a multiorgan approach that may help to evaluate patients suspected of having PE, in combination with existing protocols and computed tomographic pulmonary angiography (CTPA). We present the case of a 26-year-old man with sudden onset of dyspnoea and swelling of the leg with a Well's score of 9.

Overestimation of health urgency as a cause for emergency services inappropriate use: Insights from an exploratory economics experiment in Portugal.

Increasing visits to emergency departments add strain to public healthcare systems. The misperception of symptoms' severity can partly explain inappropriate use of hospitals' emergency departments by non-urgent patients. This paper focuses on the misperception of symptoms' severity as a cause for the inappropriate use of emergency departments.

Deep venous thrombosis of lower limbs in adolescents: a study in a tertiary hospital.

Surface-based registration between CT and US for image-guided percutaneous renal access - A feasibility study.

Purpose: As a crucial step in accessing the kidney in several minimally invasive interventions, percutaneous renal access (PRA) practicality and safety may be improved through the fusion of computed tomography (CT) and ultrasound (US) data. This work aims to assess the potential of a surface-based registration technique and establish an optimal US acquisition protocol to fuse two-dimensional (2D) US and CT data for image-guided PRA.

Methods: Ten porcine kidney phantoms with fiducial markers were imaged using CT and three-dimensional (3D) US.

Trait determinants of impulsive behavior: a comprehensive analysis of 188 rats.

Impulsivity is a naturally occurring behavior that, when accentuated, can be found in a variety of neuropsychiatric disorders. The expression of trait impulsivity has been shown to change with a variety of factors, such as age and sex, but the existing literature does not reflect widespread consensus regarding the influence of modulating effects. We designed the present study to investigate, in a cohort of significant size (188 rats), the impact of four specific parameters, namely sex, age, strain and phase of estrous cycle, using the variable delay-to-signal (VDS) task.

Finding Parameters around the Abdomen for a Vibrotactile System: Healthy and Patients with Parkinson's Disease.

Freezing of Gait (FOG) is one of the most disabling gait disorders in Parkinson's Disease (PD), for which the efficacy of the medication is reduced, highlighting the use of non-pharmacological solutions. In particular, patients present less difficulties in overcoming FOG when using feedback and especially with Biofeedback Systems. In this study it is intended to detect the frequency threshold and the minimum interval of perception of the vibrotactile feedback, through a proposed wearable system, a waistband.

Resistance of different guidewires to laser injury: an in-vitro experiment.

Background: In urology, lasers are used in a variety of endoscopic procedures such as ureteroscopy and retrograde renal surgery for stone fragmentation of urinary calculi and ablation of urothelial tumors. To perform these procedures, guidewires are used as a preliminary safe-mainstay for referencing the urinary tract. This study aims to determine the effect of two different lasers: holmium:YAG (Ho:YAG) and thulium:YAG (Tm:YAG) lasers on metal guidewires with PTFE coating (PTFE), nitinol guidewires with hydrophilic coating (Hydrophilic) and nitinol guidewires with hydrophilic listed coating (Zebra).

Ozone therapy prevents the onset of dysplasia in HPV16-transgenic mice-A pre-clinical efficacy and safety analysis.

Infection with high-risk human papillomavirus (HPV), most often HPV16, is associated with the development of anogenital and oropharyngeal cancers. Recently, ozone therapy was reported to have considerable efficacy against rabbit VX2 tumors, induced by the cottontail rabbit papillomavirus. The present study aims to determine whether similar results can be obtained in HPV16-transgenic mice, possibly paving the way for new therapeutic options against HPV-induced cancers.

Experiences During a Psychoeducational Intervention Program Run in a Pediatric Ward: A Qualitative Study.

Hospitalization, despite its duration, is likely to result in emotional, social, and academic costs to school-age children and adolescents. Developing adequate psychoeducational activities and assuring inpatients' own class teachers' collaboration, allows for the enhancement of their personal and emotional competences and the maintenance of a connection with school and academic life. These educational programs have been mainly designed for patients with long stays and/or chronic conditions, in the format of Hospital Schools, and typically in pediatric Hospitals.

Satisfaction with life in individuals with a lower limb amputation: The importance of active coping and acceptance.

The aim of this study was to analyze the relationship between sociodemographic/clinical characteristics, coping strategies and satisfaction with life in individuals with lower limb amputation. Sixty-three individuals with a lower limb amputation due to Diabetes and Peripheral Vascular Disease participated in the study and answered measures of coping strategies and satisfaction with life. Findings revealed high dissatisfaction with life.

A brain within the heart: A review on the intracardiac nervous system.

Cardiac function is under the control of the autonomic nervous system, composed by the parasympathetic and sympathetic divisions, which are finely tuned at different hierarchical levels. While a complex regulation occurs in the central nervous system involving the insular cortex, the amygdala and the hypothalamus, a local cardiac regulation also takes place within the heart, driven by an intracardiac nervous system. This complex system consists of a network of ganglionic plexuses and interconnecting ganglions and axons.

Tender red subcutaneous nodules in an adult female: a challenging diagnosis.

Pancreatic panniculitis is an uncommon and rare skin complication of systemic fat necrosis associated with pancreatitis post-ampullectomy. Besides the rarity of the condition, the clinical history and physical examination for diagnosis is also important.

Serotonin regulates prostate growth through androgen receptor modulation.

Aging and testosterone almost inexorably cause benign prostatic hyperplasia (BPH) in Human males. However, etiology of BPH is largely unknown. Serotonin (5-HT) is produced by neuroendocrine prostatic cells and presents in high concentration in normal prostatic transition zone, but its function in prostate physiology is unknown.

Solid pseudopapillary neoplasm-Case report of a rare pancreatic tumor.

Introduction: Solid pseudopapillary neoplasm (SPN) is a rare pancreatic tumor. Most patients are female within the second or third decade of life with only a small minority concerning children. Frequently described as low malignant potential tumors, surgical resection remains the main treatment.

The Impact of Prenatal Exposure to Dexamethasone on Gastrointestinal Function in Rats.

Antenatal treatment with synthetic glucocorticoids is commonly used in pregnant women at risk of preterm delivery to accelerate tissue maturation. Exposure to glucocorticoids during development has been hypothesized to underlie different functional gastrointestinal (GI) and motility disorders. Herein, we investigated the impact of in utero exposure to synthetic glucocorticoids (iuGC) on GI function of adult rats.
