The incidence of early-onset colorectal cancer (CRC), defined as CRC occurring in individuals younger than 50 years, is increasing globally. Emerging evidence suggests that the incidence and prevalence of CRC in individuals aged 45-49 years approach those in individuals aged 50-59 years. To address this concerning trend, many health care systems and clinical specialist societies are advocating for lowering the age of initiation for CRC screening in individuals at average risk to 45 years. The present review, provided by the Canadian Association of General Surgeons Clinical Practice Committee, gives an overview of the current CRC screening guidelines in Canada, the rationale for earlier screening, and the challenges and impact of lowering the screening age to 45 years to health care systems in Canada.

Blowflies are important to estimate the postmortem interval (PMI), since they are the first to interact with the carcass. However, depending on the decomposition stage, only pupae can be found. A method that has currently been suggested is the use of cuticular hydrocarbons (CHCs) in forensically important fly species to aid in estimating PMI; however, studies from the pupal stage are rare.

Objective: SURMOUNT-MAINTAIN aims to evaluate the efficacy and safety of reducing the tirzepatide dose and/or continuing the maximum tolerated dose (MTD) versus placebo in maintaining body weight (BW) reduction achieved with tirzepatide MTD.
Methods: This Phase 3b, multicenter, randomized, parallel-arm, double-blinded, placebo-controlled, 52-week clinical trial is in progress comparing treatment with once weekly tirzepatide (5 mg and/or MTD of 15 mg or 10 mg) versus placebo in achieving BW reduction maintenance from the initial 60-week open-label weight-loss period on tirzepatide MTD, in adults with obesity (BMI ≥ 30 kg/m or ≥ 27 kg/m with ≥ 1 obesity-related comorbidity, excluding type 2 diabetes). The primary endpoint is percent maintenance of BW reduction achieved during the weight-loss period at Week 112 among those who reached a BW plateau (i.

Objective: To evaluate the clinical efficacy of tocilizumab, a interleukin-6 (IL-6) receptor blocker, for the treatment of acute necrotizing encephalopathy (ANE).
Methods: PubMed, Cochrane Library, Embase, and Web of Science were searched for systematic review based on PRISMA guidelines. ANE patients treated with and without tocilizumab were included.

Recent improvements in cell-free DNA technology have enabled non-invasive prenatal testing (NIPT) to screen for fetal single-gene autosomal recessive conditions from maternal blood as early as the first trimester. This technique can determine the fetal risk for cystic fibrosis (CF) with a single blood sample from a pregnant person without the need for a partner sample, which is required for traditional carrier screening. A retrospective review of 100,106 consecutive general-risk pregnant patients who underwent CF carrier screening was completed.

Study Objectives: This study compares the demographic characteristics and experiences of three different groups of adolescent and young adults (AYAs) seeking non-sedated intrauterine device (IUD) insertion in the outpatient setting: (1) cisgender individuals, (2) transgender and gender diverse (TGD) individuals receiving gender-affirming testosterone therapy, and (3) TGD individuals not receiving gender-affirming testosterone therapy.
Methods: This retrospective cohort study included AYAs age 13 to 21 years seeking IUD insertion. Data were obtained from the electronic health record via a pre-existing, multi-institutional shared quality improvement (QI) collaborative.
