Objectives: Advanced combination treatment (ACT), defined as a combination of at least 2 biologic agents, a biologic agent and an oral small molecule, 2 oral small molecules drug with different mechanisms of action is a proposed strategy to improve outcomes in patients with immune-mediated inflammatory disease (IMID). We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing ACT with monotherapy in patients with select IMIDs.

Methods: Through a systematic literature search, we identified 10 RCTs (n = 1154) comparing ACT with single agent therapy (monotherapy).

Introduction: Prader-Willi syndrome (PWS) is a genetic disorder characterized by hypothalamic-pituitary deficiencies including hypogonadism. In girls with PWS, hypogonadism can present early in childhood, leading to genital hypoplasia, delayed puberty, incomplete pubertal development, and infertility. In contrast, girls can present with premature activation of the adrenal axis leading to early pubarche and advanced bone age.

Vascular calcification is prevalent in chronic kidney disease (CKD). Genetic causes of CKD account for 10-20% of adult-onset disease. Vascular calcification is thought to be one of the most important risk factors for increased cardiovascular morbidity and mortality in CKD patients and is detectable in 80% of patients with end stage kidney disease (ESKD).

SARS-CoV-2, responsible for COVID-19, shares 79% and 50% of its identity with SARS-CoV-1 and MERS-CoV, respectively. It uses the same main cell attachment and entry receptor as SARS-CoV-1, which is the ACE-2 receptor. However, key residues in the receptor-binding domain of its S-protein seem to give it a stronger affinity for the receptor and a better ability to hide from the host immune system.

Investigation of ,,-Trimethyl-L-alanyl-L-proline Betaine (TMAP) as a Biomarker of Kidney Function.

Department of Physiology and Pharmacology, Schulich School of Medicine and Dentistry, University of Western Ontario, London, Ontario N6A 3K7, Canada.

Glomerular filtration rate (GFR) is the most widely used tool for the measurement of kidney function, but endogenous biomarkers such as cystatin C and creatinine have limitations. A previous metabolomic study revealed ,,-trimethyl-L-alanyl-L-proline betaine (TMAP) to be reflective of kidney function. In this study, we developed a quantitative LCMS assay for the measurement of TMAP and evaluated TMAP as a biomarker of GFR.

We present a unique case of a 6 cm, incidental, ureteral myopericytoma which was initially believed to be an ovarian tumor with mass effect, causing hydroureteronephrosis. A 75-year-old woman presented with a three-month history of postprandial cramps and heartburn. A right distal ureterectomy with en-bloc resection of the mass was performed.

The multifaceted role of GCM1 during trophoblast differentiation in the human placenta.

Department of Anatomy and Cell Biology, Schulich School of Medicine and Dentistry, University of Western Ontario, London N6A 5C1, Canada.

Remodeling of the uterine vasculature by invasive extravillous trophoblasts (EVTs) is a critical aspect of human placentation. Insufficient EVT invasion can lead to severe obstetrical complications like preeclampsia, intrauterine growth restriction, and preterm birth. Glial cells missing-1 (GCM1) is a transcription factor that is crucial for proper placentation in mice, and is highly expressed in human syncytiotrophoblast (ST) and EVTs.

Background: Soft tissue management (STM) training programs for surgeons are largely tradition based, and substantial differences exist among different surgical specialties. The lack of comprehensive and systematic clinical evidence on how surgical techniques and implants affect soft tissue healing makes it difficult to develop evidence-based curricula. As a curriculum development group (CDG), we set out to find common grounds in the form of a set of consensus statements to serve as the basis for surgical soft tissue education.

Background: Anlotinib demonstrated improved overall survival (OS) and progression-free survival (PFS) compared with placebo as a third-line or subsequent therapy in patients with non-small cell lung cancer (NSCLC) in the ALTER0303 trial. The status of epidermal growth factor receptor (EGFR) mutation, different previous treatment may affect the efficacy of subsequent therapy, and we did this subgroup analysis to characterize the efficacy of anlotinib in patients with and without EGFR mutation.

Methods: The ALTER0303 trial was a randomized, double-blind, phase 3 study of anlotinib in patients with NSCLC who failed at least 2 lines of treatment.

() is a Gram-negative bacillus abundant in the environment and rarely implicated in human disease. Previously considered nonpathogenic, its scarcity in literature may be partly due to the unreliability of past phenotypic tests used for its identification. In recent years, the development of matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry (MS) has enabled fast and accurate laboratory identification of .

Background: Intrinsic or acquired resistance to epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) is common, thus strategies for the management of EGFR-TKIs resistance are urgently required. Ferroptosis is a recently discovered form of cell death that has been implicated in tumorigenesis and resistance treatment. Accumulating evidence suggests that ferroptosis can be therapeutically exploited for the treatment of solid tumors; however, whether ferroptosis can be targeted to treat mutant lung cancer and/or overcome the resistance to EGFR-TKIs is still unknown.

Biomechanical analysis of fixation methods for acetabular fractures: A review.

Med Eng Phys

March 2021

Department of Mechanical Engineering, George Mason University, 4400 University Dr, Fairfax, VA 22030, USA. Electronic address:

Acetabular fractures are known as one of the most frequent types of pelvic fractures with growing frequency among elderly people. Because of this, it is important to establish the methods of repair that will produce optimal outcomes for fracture healing and joint remobilization. Open reduction and internal fixation are considered as the "gold standard" of acetabular fracture repair; however, to the best of authors' knowledge, there is no systematic review comparing different repair methods from biomechanical point of view.
