An Opioid-Sparing Pain Protocol of Intravenous and Oral Ketorolac Reduces Opioid Consumption and Pain Levels After Arthroscopic Meniscus Surgery: A Prospective, Randomized Controlled Trial.

Background: The primary purpose was to compare ketorolac to oxycodone-acetaminophen with respect to pain and opioid consumption after arthroscopic meniscus surgery. The secondary purpose was to compare short-term functional outcomes between the 2 protocols.

Methods: A power analysis demonstrated that 43 patients were required.

Identifying patterns of reported findings on long-term cardiac complications of COVID-19: a systematic review and meta-analysis.

Introduction: Prior reviews synthesized findings of studies on long-term cardiac complications of COVID-19. However, the reporting and methodological quality of these studies has not been systematically evaluated. Here, we conducted a systematic review and meta-analysis on long-term cardiac complications of COVID-19 and examined patterns of reported findings by study quality and characteristics.

Suppressed charge recombination defect engineering of confined semiconducting quantum dots for photoelectrocatalysis.

Confined semiconducting CuSe quantum dots with abundant Se vacancies are synthesized by pulsed laser deposition with vacuum annealing. With the presence of Se vacancies, the photogenerated charge recombination is suppressed by the self-introduced in-gap trapping states, thus enhancing the photoelectrocatalytic activity under solar illumination.

Total Ankle Arthroplasty for Posttraumatic Fracture Versus Primary Osteoarthritis: An Analysis of Complications, Revisions, and Prosthesis Survival.

Background: Most outcome studies of total ankle arthroplasty (TAA) do not discriminate by arthritis etiology. The primary purpose of this study was to compare the complications of TAA between posttraumatic fracture osteoarthritis (fracture PTOA) and primary osteoarthritis (POA).

Methods: Ninety-nine patients who underwent TAA were retrospectively evaluated with a mean follow-up of 3.

Outcomes of Geriatric Periprosthetic Distal Femur Fractures: Comparison of Fixation Versus Reconstruction.

Objective: Comparing outcomes of periprosthetic distal femur fractures treated with open reduction and internal fixation (ORIF) versus distal femoral replacement (DFR).

Setting: Three major academic hospitals within one metropolitan area.

Design: Retrospective.

Long-term cardiac symptoms following COVID-19: a systematic review and meta-analysis.

Background: There is growing body of literature on the long-term cardiac symptoms following COVID-19. We conducted a systematic review and meta-analysis to synthesize and evaluate related evidence to inform clinical management and future studies.

Methods: We searched two preprint and seven peer-reviewed article databases from January 1, 2020 to January 8, 2022 for studies investigating cardiac symptoms that persisted for at least 4 weeks among individuals who survived COVID-19.

Efficient Charge Transfers in Highly Conductive Copper Selenide Quantum Dot-Confined Catalysts for Robust Oxygen Evolution Reaction.

Defective quantum dots (QDs) are the emerging materials for catalysis by virtue of their atomic-scale size, high monodispersity, and ultra-high specific surface area. However, the dispersed nature of QDs fundamentally prohibits the efficient charge transfer in various catalytic processes. Here, we report efficient and robust electrocatalytic oxygen evolution based on defective and highly conductive copper selenide (CuSe) QDs confined in an amorphous carbon matrix with good uniformity (average diameter 4.

Longitudinal Changes in Subclinical Vascular Disease in Ugandan Youth With Human Immunodeficiency Virus.

Background: Prospective investigations on the risk of cardiovascular disease among youth with perinatally acquired human immunodeficiency virus (PHIV) in sub-Saharan Africa are lacking.

Methods: A prospective observational cohort study was performed in 101 youth (aged 10-18 years) with PHIV and 97 who were human immunodeficiency virus (HIV) uninfected (HIV-), from 2017 to 2021 at the Joint Clinical Research Center in Uganda. Participants with PHIV were receiving antiretroviral therapy (ART) and had HIV-1 RNA levels ≤400 copies/mL.
