COVID-19 has brought death and disease to large parts of the world. Governments must deploy strategies to screen the population and subsequently isolate the suspect cases. Diagnostic testing is critical for epidemiological surveillance, but the accuracy (sensitivity and specificity) and clinical utility (impact on health outcomes) of the current diagnostic methods used for SARS-CoV-2 detection are not known. I ran a quick search in PubMed/MEDLINE to find studies on laboratory diagnostic tests and rapid viral diagnosis. After running the search strategies, I found 47 eligible articles that I discuss in this review, commenting on test characteristics and limitations. I did not find any papers that report on the clinical utility of the tests currently used for COVID-19 detection, meaning that we are fighting a battle without proper knowledge of the proportion of false negatives that current testing is resulting in. This shortcoming should not be overlooked as it might hamper national efforts to contain the pandemic through testing community-based suspect cases.

Contemporary Cytomegalovirus (CMV) Infections in Low-Risk CMV Seronegative Recipients of Solid Organ Transplants From CMV Seronegative Donors (D-/R-): Time to Reexamine Donor CMV Serostatus.
Clin Transplant
January 2025
Division of Infectious Diseases, Department of Medicine, Duke University School of Medicine, Durham, North Carolina, USA.
Background: Early posttransplant cytomegalovirus (CMV) infections in CMV seronegative solid organ transplant recipients (SOTR) with CMV seronegative donors (D-/R-) are often attributed transfusion-transmitted CMV. The prevalence of false-negative donor CMV serology in D-/R- SOTR with early CMV infections has not been explored.
Methods: We determined the frequency and characteristics of CMV DNAemia that occurred within 90 days of transplant among adult SOTR classified as D-/R- who underwent a first SOT at a single center between February 25, 2014 and February 25, 2024.

December 2024
General Surgery, Aneurin Bevan University Health Board, Newport, GBR.
Aim: To assess recent colonoscopies and CT scans in conjunction with the feacal immunochemical test (FIT) for possibly downgrading urgent suspected cancer (USC) referrals.
Methods: A retrospective single-centre study was conducted, including all USC referrals for colonoscopy in 2022, excluding anal cancers. The CT and colonoscopy findings for a two-year period prior to the referral, along with the FIT result (if done), were noted.
Recurrence rate of corneal squamous cell carcinoma in dogs undergoing superficial keratectomy surgery.
Open Vet J
November 2024
Animal Eye Care, Melbourne, Australia.
Background: Corneal squamous cell carcinoma (cSCC) is a rare neoplasm of dogs that can be treated with various modalities, principally by superficial keratectomy (SK) surgery. It is common to treat cSCC with multiple adjunctive therapies, but this may not always be practical for clinicians, clients, or patients.
Aim: This retrospective study describes the signalment of affected dogs, concurrent medical therapy, and success rate of surgical treatment of cSCC with SK surgery alone or in combination with adjunct therapy.
Bronchial artery pseudoaneurysm presenting with hemoptysis and hemothorax after pulmonary lobectomy: a case report and literature review.
J Cardiothorac Surg
December 2024
Department of Thoracic Surgery, The Second Hospital of Jilin University, Changchun, Jilin, 130041, PR China.
Background: Bronchial artery pseudoaneurysm is a rare vascular disorder, and cases of bronchial pseudoaneurysms reported after lung surgery are even rarer. The number of reported cases is very limited due to the unclear pathogenesis, lack of diagnostic criteria and treatment guidelines, and nonspecific clinical manifestations.
Case Presentation: The paper reports a case of a patient with primary lung adenocarcinoma who developed hemoptysis, chest and back pain, and right hemothorax after lobectomy.
