Case control study of access to medications during COVID-19 and longitudinal impact on health outcomes for primary care patients managing multiple chronic conditions.

Background: During coronavirus disease 2019 (COVID-19), people managing multiple chronic conditions (MCCs) experienced barriers to obtaining needed medications. The purposes of this paper are to (i) determine risk factors for difficulty obtaining medications during COVID-19, (ii) document reasons for the difficulty, and (iii) evaluate the impact on later physical and mental health outcomes.

Method: In a randomized controlled trial conducted in 2016-2021, 1969 adult primary care patients were surveyed about physical and mental health both before and during COVID-19.

Renal Failure in Type A-Aortic Dissection Repair: The Society of Thoracic Surgeons Adult Cardiac Surgery Database Analysis.

Background: We sought to identify predictors of acute renal failure (ARF) following acute type A aortic dissection (ATAAD) and its implications on postoperative outcomes.

Methods: ATAAD cases were identified from The Society of Thoracic Surgeons - Adult Cardiac Surgery Database (2017-2022). Cases with chronic dissection, prior aortic repair, primary endovascular repair, preoperative extracorporeal membrane oxygenation, preoperative renal failure, and operative room deaths were excluded.

From loose sand to sandstone: An experimental approach on early calcite precipitation in sands of siliciclastic and mixed carbonate-siliciclastic composition.

Artificially cemented sandstones were produced to assess the impact of detrital texture and composition on the precipitation and distribution of early calcite cement, and cement-related degradation in porosity. To simulate early-calcite cementation, loose sediment of variable composition (siliciclastic and calcareous) and grain size was exposed to a calcite supersaturated solution for 35 to 58 days at 23°C. Identification and distribution of the newly precipitated crystals was performed with high resolution 2D optical and scanning electron microscopy.

Impact of Hospital Transfers on Cardiac Surgery Outcomes: A Society of Thoracic Surgeons Adult Cardiac Surgery Database Analysis.

Background: Transfers for cardiac surgery are not well studied. We sought to understand the risk profile of transferred patients and determine whether transfer rates vary by cardiac surgery and whether outcomes of transferred patients vary with type of referral hospital/surgery.

Methods: Patients undergoing cardiac surgery with operative risk models were identified from The Society of Thoracic Surgeons database between July 1, 2014, and December 31, 2022.

Predictors of Discharge With Supplemental Oxygen After Lobectomy for Lung Cancer.

Background: Before lung cancer resection, patients inquire about dyspnea and the potential need for supplemental oxygen. The objective of this study was to identify predictors of discharge with supplemental oxygen for patients undergoing lobectomy for lung cancer.

Methods: Using The Society of Thoracic Surgeons General Thoracic Surgery Database, study investigators conducted a retrospective cohort study of patients who underwent lobectomy for lung cancer from July 2018 to December 2021.
