A Vision Language Correlation Framework for Screening Disabled Retina.

Retinopathy is a group of retinal disabilities that causes severe visual impairments or complete blindness. Due to the capability of optical coherence tomography to reveal early retinal abnormalities, many researchers have utilized it to develop autonomous retinal screening systems. However, to the best of our knowledge, most of these systems rely only on mathematical features, which might not be helpful to clinicians since they do not encompass the clinical manifestations of screening the underlying diseases.

Activation of the Alpha 7 Nicotinic Acetylcholine Receptor by GTS-21 Mitigates Contrast Nephropathy in a Rat Model.

Introduction: Contrast nephropathy (CN) is characterized by oxidative stress, vasoconstriction, tubular toxicity, and hypoxia of the renal medulla. We aimed to test the therapeutic effects of an α7 nicotinic acetylcholine receptor (nAChR) agonist, GTS-21, in an experimental CN model.

Methods: Male Sprague-Dawley rats (n = 40) were divided into 4 groups: saline-treated control, GTS-21-treated control, contrast, and GTS-21-treated contrast groups.

Pulmonary Embolism in a Liver Donor: A Case Report and Review of the Literature.

Liver transplant is an important treatment option for end-stage liver disease, and living related donation is an option to shorten or eliminate the waiting period for the patients, especially when shortage of organs is of concern. It is crucial to provide optimal safety for the donors and to thoroughly examine them preoperatively in order to decrease perioperative and postoperative complications. Here, we report the case of a living donor who had undergone a left liver lobectomy and on postoperative day 2 presented with a radiologically severe pulmonary embolism, despite the absence of any risk factor for venous thromboembolism or pulmonary embolism.

Can adipokines predict clinical prognosis and post-COVID lung sequelae?

Background: Adipokines play an important role in the regulation of inflammatory responses toward infections, including COVID-19. This study aimed to investigate the role of chemerin, adiponectin, and leptin in prognosis and post-COVID lung sequelae in hospitalized patients with COVID-19.

Methods: Serum levels of the three adipokines were measured upon admission of polymerase chain reaction-confirmed patients with COVID-19 who were followed up for 6 months for the clinical outcome and lung sequelae formation.

Has the pandemic changed the test quality of the pulmonary function test laboratory?

Introduction: Pulmonary function tests are used in the evaluation of the respiratory system. Maneuvers during spirometry can create aerosols and spread viruses such as SARS-CoV-2. Measures due to the pandemic can negatively affect both the number and the quality of the spirometry tests.
