Impact of Bifurcation Lesions on Outcomes After FFR-Guided PCI or CABG.

Circ Cardiovasc Interv

December 2024

Department of Cardiology, Catharina Hospital, Eindhoven, the Netherlands (D.M.M.D., K. Teeuwen, P.A.L.T., N.H.J.P., F.M.Z.).

Background: In the era of first-generation drug-eluting stents and angiography-guided percutaneous coronary intervention (PCI), the presence of a bifurcation lesion was associated with adverse outcomes after PCI. In contrast, the presence of a bifurcation lesion had no impact on outcomes following coronary artery bypass grafting (CABG). Therefore, the presence of a coronary bifurcation lesion requires special attention when choosing between CABG and PCI.

December 2024

Department of Neuropsychiatry, Keio University School of Medicine, 35 Shinanomachi, Shinjuku, Tokyo 160-8582, Japan; Shinjuku-Yoyogi Mental Lab Clinic, 5-27-5 Sendagaya, Shibuyaku, Tokyo, 151-0051, Japan; Department of Psychiatry, International University of Health and Welfare, Mita Hospital, 1-4-3 Mita, Minato-ku Tokyo, 108-8329 Japan. Electronic address:

Background: Bilateral repetitive transcranial magnetic stimulation (BL-rTMS) over the dorsolateral prefrontal cortex is effective for treatment-resistant depression (TRD). Owing to a shorter treatment time, bilateral theta burst stimulation (BL-TBS) can be more efficient protocol. The non-inferiority of BL-TBS to BL-rTMS was established in late-life TRD; however, this has not been determined in adults of other age groups.

JBJS convened a symposium to discuss the reporting of sex and gender in research studies as an imperative to improve research methods and results to benefit all patients. Barriers to improved reporting include a lack of societal and cultural acceptance of its need; a lack of education regarding appropriate terminology and appropriate statistical methods and efficient study designs; a need for increased research funding to support larger group sizes; unknown concordance of cell and animal models with humans to reflect biologic variables such as sex; and a lack of understanding of key considerations of gender, race, and other social determinants of health and how these factors intersect. Attention to developing and disseminating best-practice statistical methods and to educating investigators (at all career levels), reviewers, funders, editors, and staff in their proper implementation will aid reporting.

High Shear Stress Reduces ERG Causing Endothelial-Mesenchymal Transition and Pulmonary Arterial Hypertension.

Arterioscler Thromb Vasc Biol

December 2024

Department of Pediatrics (T.S., J.-R.M., Y.H.C., J.M.S., J. Kaplan, A.C., L.W., D.G., S.T., S.I., M.D., W.Y., A.L.M., M.R.).

Background: Computational modeling indicated that pathological high shear stress (HSS; 100 dyn/cm) is generated in pulmonary arteries (PAs; 100-500 µm) in congenital heart defects causing PA hypertension (PAH) and in idiopathic PAH with occlusive vascular remodeling. Endothelial-to-mesenchymal transition (EndMT) is a feature of PAH. We hypothesize that HSS induces EndMT, contributing to the initiation and progression of PAH.

Objectives: Urothelial carcinoma in situ (CIS) with early papillary formation is terminology sometimes used to suggest incipient high-grade papillary urothelial carcinoma (PUC) but may lead to confusion between true CIS and lateral flat spread of PUC.

Methods: It remains unclear how pathologists and urologists interpret this scenario, so a survey was circulated to 68 pathologists (group 1 = 28 academic genitourinary pathologists; group 2 = 17 pathologists with a self-reported genitourinary focus; group 3 = 23 pathologists self-reported as not genitourinary specialists) and 32 urologists.

Results: Regarding atypical urothelial lesions that appear mainly flat but contain possible papillae, group 3 was more likely to label this as CIS compared with groups 1 and 2 (35% for group 3 vs 13% for groups 1 and 2), while groups 1 and 2 more often adopted another descriptive diagnosis, such as "CIS with early papillary features" (38% for groups 1 and 2 vs 13% for group 3).

Patients with osteosarcoma (OS), a debilitating pediatric bone malignancy, have limited treatment options to combat aggressive disease. OS thrives on insulin growth factor (IGF)-mediated signaling that can facilitate cell proliferation. Previous efforts to target IGF-1R signaling were mostly unsuccessful, likely due to compensatory signaling through alternative splicing of the insulin receptor () to the proliferative isoform.

Description: Gastric cancer (GC) is a leading cause of preventable cancer and mortality in certain US populations. The most impactful way to reduce GC mortality is via primary prevention, namely Helicobacter pylori eradication, and secondary prevention, namely endoscopic screening and surveillance of precancerous conditions, such as gastric intestinal metaplasia (GIM). An emerging body of evidence supports the possible impact of these strategies on GC incidence and mortality in identifiable high-risk populations in the United States.
