Unlocking the clinical potential of paired inspiratory and expiratory CT scans in the differential diagnosis of cystic lung diseases: A systematic review.

Introduction: Currently, high-resolution computed tomography (HRCT) is the imaging of choice for the differential diagnosis of various cystic lung lesions, including true cystic lung diseases (CLD) and lesions that may mimic them. However, the traditionally used inspiratory scan still presents a significant spectrum of overlapping radiological features. Recent studies have demonstrated variation in lesion size between inspiratory and expiratory phases, probably due to cyst-airway communication.

Nutritional Value of the Larvae of the Black Soldier Fly () and the House Fly () as a Food Alternative for Farm Animals-A Systematic Review.

Dietary alternatives using insect-based products as an alternative for farm animal nutrition have been the object of study due to the high nutritional value of these feeds and the costs related to both their production and consequently their commercialization. Thus, the use of flies, especially larvae, has a high content of proteins and lipids (fat), as well as minerals and essential nutrients for development and growth, directly impacting the production of these animals, whether meat or milk. Therefore, the objective of this study was to compile data from the literature on the nutritional value of adults and larvae of Black soldier () and housefly () as a dietary alternative for animal feed.

Detection of Liver Lesions in Colorectal Cancer Patients Using F-FDG PET/CT Dual-Time-Point Scan Imaging.

Objective: The aim of this study was to evaluate the diagnostic performance of dual-time-point fluorine-18-fluorodeoxyglucose positron emission computed tomography/computed tomography (F-FDG PET/CT) compared to conventional early imaging for detecting colorectal liver metastases (CRLM) in colorectal cancer (CRC) patients.

Methods: One hundred twenty-four consecutive CRC patients underwent dual-time-point imaging scans on a retrospective basis. Histopathological confirmation and/or clinical follow-up were accepted as the gold standard.

Deep Learning Algorithms for Diagnosis of Lung Cancer: A Systematic Review and Meta-Analysis.

We conducted a systematic review and meta-analysis of the diagnostic performance of current deep learning algorithms for the diagnosis of lung cancer. We searched major databases up to June 2022 to include studies that used artificial intelligence to diagnose lung cancer, using the histopathological analysis of true positive cases as a reference. The quality of the included studies was assessed independently by two authors based on the revised Quality Assessment of Diagnostic Accuracy Studies.

Postoperative computed tomography of insufflated lung specimens obtained by video-assisted thoracic surgery: detection and margin assessment of pulmonary nodules.

Objective: To investigate the utility of computed tomography (CT) scans to detect and assess the margin status of pulmonary nodules that were insufflated after being resected by video-assisted thoracic surgery.

Materials And Methods: This was a novel multicenter study conducted at two national referral centers for thoracic diseases. Patients suspected of having lung cancer underwent video-assisted thoracic surgery for the resection of pulmonary nodules, which were submitted to postoperative CT.

Myocardial Injury in Patients With Acute and Subacute Chagas Disease in the Brazilian Amazon Using Cardiovascular Magnetic Resonance.

Background Chagas disease is a neglected tropical disease that is still considered a global health emergency. In the Amazon region, most of the reports are of acute cases that are associated with oral transmission. This study aimed to evaluate myocardial injury in patients with acute Chagas disease before and after treatment.

Evaluation of peripheral nerve injury by magnetic resonance neurography: A systematic review.

In view of the limitations of current methods for assessing peripheral nerve injury, there is a need for technical innovations to improve diagnosis, surgical approach and postoperative monitoring. The objective of this study was to conduct a systematic review to analyze the applicability of magnetic resonance neurography in peripheral nerve injuries. The present systematic review focused on the use of magnetic resonance neurography.

Comparative Study of Electrical Stimulation of the Heart with VDD and DDD Pacemakers as to the Evolution to Atrial Fibrillation.

Introduction: The pacemaker implantation VDD is considered simpler, faster, less expensive and causes fewer complications compared to DDD. However, the VDD pacemaker has not been widely used in many centers, perhaps for fear of dysfunction of the sinus node and the reduction of atrial sensitivity by the pacemaker during follow-up after implantation.

Objective: To compare patients with DDD and VDD pacemakers regarding the evolution of chronic atrial fibrillation (AF) and length of stay outside this postoperative arrhythmia.

Oral anticoagulation in carriers of mechanical heart valve prostheses: experience of ten years.

Background: Published data suggest that rates of thromboembolism and bleeding, in patients with mechanical heart valve prostheses, can be very small by optimizing current anticoagulant therapy.

Objective: To evaluate the occurrence of complications in patients with mechanical heart valve prostheses undergoing anticoagulant therapy optimized through specialized clinics.

Methods: We studied the occurrence of complications over 10 years in 261 anticoagulated patients with mechanical heart valve prostheses, followed in specialized clinics.

Cystatin C and glomerular filtration rate in the cardiac surgery with cardiopulmonary bypass.

Objective: The aim of this study was to compare cystatin C versus creatinine as a marker for acute kidney injury in patients submitted to cardiac surgery with cardiopulmonary bypass.

Methods: Fifty consecutive patients submitted to coronary artery bypass grafting were studied. Renal function was evaluated by serum cystatin C and creatinine.

Primary idiopathic chylopericardium--case report.

The accumulation of chyle in the pericardial space, or chylopericardium, is a condition occurring most frequently after trauma, cardiac and thoracic surgery, or in association with tumors, tuberculosis or lymphangiomatosis. When its precise cause cannot be identified, it is called primary or idiopathic chylopericardium. This is a rare clinical entity.

Partial absence of the inferior vena cava associated with bowel malformation.

A 6-year-old female child sought medical service due to a gastrointestinal malformation. During medical follow-up, partial absence of the inferior vena cava was diagnosed, a rare congenital alteration affecting the vascular drainage from the inferior segment of the body. Imaging exams were accomplished, contributing to evaluation and description of the case.

Preoperative risk factors for the development of acute renal failure in cardiac surgery.

Objective: To evaluate clinical risk factors for the development of Acute Renal Failure (ARF) in patients who undergo cardiac surgery.

Method: Over a period of 21 consecutive months, one hundred and fifty patients who underwent cardiac surgery were studied. There was a slight prevalence of men (57%) and the average age was 56 +/- 14.
