Study Design: Case report.
Objectives: Case report of acute renal infarction following lateral interbody fusion with posterior instrumentation for adult lumbar kyphoscoliosis.
Summary Of Background Data: This is the first reported renal infarction following minimally invasive lateral interbody fusion and posterior spinal instrumentation.
Methods: We report a case of acute renal infarction in a 72-year-old woman following direct lateral interbody fusion (DLIF) with percutaneous pedicle screw and rod fixation from L1 to L5 for correction of kyphoscoliosis. She reported vague abdominal pain on postoperative day (POD) 7. Abdominal ultrasound findings revealed no abnormalities. The patient tolerated a regular diet, improved in rehabilitative modalities, and had stable vital signs. Abdominal computed tomographic (CT) scan on POD 9 for persistent abdominal pain revealed right renal infarction and right renal artery occlusion. The patient was transferred to the ICU for evaluation, where intravenous heparin was administered and no reperfusion was performed. Transesophageal echocardiography on POD 14 revealed moderate diffuse plaque in the descending aorta.
Results: Surgical correction of kyphoscoliosis through DLIF and posterior spinal instrumentation was performed with improvement of deformity. Subsequent acute renal infarction was noted. The patient was discharged home on POD 21. There were no further adverse events up to the 1-year follow-up.
Conclusions: A lateral approach to the anterior lumbar spine may precipitate renal artery occlusion and renal infarction in patients with atherosclerosis. Diagnosis of renal infarction requires a high index of suspicion because the primary complaint may be vague back, flank, and abdominal pain. We emphasize the importance of recognizing potential symptoms early to prevent additional renal injury. Caution should be taken with deformities around the origin of the renal arteries and great vessels, especially in patients with atherosclerosis.
Level Of Evidence: Level IV.

Importance: Cardiovascular health outcomes associated with noncigarette tobacco products (cigar, pipe, and smokeless tobacco) remain unclear, yet such data are required for evidence-based regulation.
Objective: To investigate the association of noncigarette tobacco products with cardiovascular health outcomes.
Design, Setting, And Participants: This cohort study was conducted within the Cross Cohort Collaboration Tobacco Working Group by harmonizing tobacco-related data and conducting a pooled analysis from 15 US-based prospective cohorts with data on the use of at least 1 noncigarette tobacco product ranging between 1948 and 2015.
Coronary artery calcification progression and renal involvement in patients with systemic lupus erythematosus: a longitudinal cohort study.

To investigate if progression of coronary artery calcification (CAC) in patients with systemic lupus erythematosus (SLE) is associated with renal and traditional cardiovascular risk factors as well as incidence of myocardial infarctions. CAC progression was evaluated by cardiac computed tomography (CT) at baseline and after 5 years. Multivariable Poisson regression was applied to investigate associations between CAC progression and baseline values for traditional cardiovascular risk factors, CAC, SLE disease duration, lupus nephritis, and renal function.

Background: The urinary albumin-to-creatinine ratio (UACR) or urinary protein-to-creatinine ratio (UPCR) has been reported as predictors of cardiovascular and renal events. We aimed to evaluate the impact of changes in proteinuria severity on the prognosis of hypertensive patients post-esaxerenone initiation.
Methods And Results: Hypertensive patients who commenced esaxerenone (n=164) were classified into 3 groups according to baseline UACR or UPCR, based on the modified proteinuria severity classification: A1 (normal; n=35); A2 (microalbuminuria/mild proteinuria; n=49); and A3 (macroalbuminuria/severe proteinuria; n=80).
Newly Initiated Statin Treatment Is Associated with Decreased Plasma Coenzyme Q10 Level After Acute ST-Elevation Myocardial Infarction.

Coenzyme Q10 (CoQ10) plays a crucial role in facilitating electron transport during oxidative phosphorylation, thus contributing to cellular energy production. Statin treatment causes a decrease in CoQ10 levels in muscle tissue as well as in serum, which may contribute to the musculoskeletal side effects. Therefore, we aimed to assess the effect of newly initiated statin treatment on serum CoQ10 levels after acute ST-elevation myocardial infarction (STEMI) and the correlation of CoQ10 levels with key biomarkers of subclinical or clinically overt myopathy.

Objective: Patients with chronic kidney disease (CKD) have an increased risk of adverse cardio-cerebrovascular events. The purpose of this study is to evaluate the prognostic predictors over 5 years in patients with CKD including haemodialysis.
Methods: In this multicenter, prospective cohort study performed with the Gunma-CKD SPECT Study protocol, 311 patients with CKD [estimated glomerular filtration rate (eGFR) < 60 min/ml/1.
