Association of iron therapy with incidence of chronic kidney disease.

Objective: We investigated the association of oral iron replacement with the incidence of chronic kidney disease (CKD) in a population with normal kidney function to study the effects of iron replacement on the development of new onset CKD.

Methods: In a national cohort of US Veterans with no pre-existing CKD, we identified 33 894 incident new users of oral iron replacement and a comparable group of 112 780 patients who did not receive any iron replacement during 2004-2018. We examined the association of oral iron replacement versus no iron replacement with the incidence of eGFR <60 mL/min/1.

Prevalence of congenital scoliosis in infants based on chest-abdomen X-ray films detected in the emergency department.

Purpose: To investigate the prevalence of congenital scoliosis (CS) in infants based on chest-abdomen radiographs.

Methods: A retrospective review was conducted on infants in the emergency department (ED) of a tertiary children's hospital between February 2008 and September 2019. Patients who had undergone chest-abdomen X-rays were included.

Repair of iatrogenic ureteral injury secondary to breast cancer metastasis.

We present a case of unforeseen ureteral metastasis from a primary breast cancer. A ureteral injury leak was postoperatively recognized after a hysterectomy and bilateral oophorectomy were performed. Subsequent repair with a psoas hitch ureteral re-implant was performed and breast cancer metastasis was discovered in the ureteral stump specimen.

A Case of Early Prosthetic Valve Endocarditis Caused by in a Patient Presenting With Congestive Heart Failure.

, a coagulase negative staphylococcus, has been isolated in prosthetic device-related infections and has been reported as a rare cause of endocarditis. We report a case of prosthetic aortic valve endocarditis, in which the patient lacked typical infectious signs and symptoms, instead presenting with congestive heart failure due to perforation of the valve. Providers should consider endocarditis with a low virulence pathogen such as when a patient with a prosthetic valve presents with heart failure, even in the absence of fever, leukocytosis and other infectious symptoms.

The Marriage Checkup: a randomized controlled trial of annual relationship health checkups.

Objective: This study assessed the efficacy of the Marriage Checkup (MC) for improving relationship health and intimacy.

Method: Cohabiting married couples (N = 215, Mage women = 44.5 years, men = 47 years, 93.

Piecemeal necrosis of the liver revisited a review.

Piecemeal necrosis of the liver is thought to lead to liver cell necrosis. However the process does not lead to necrosis but rather lead to gradual progressive piecemeal removal of liver cell cytoplasm by T lymphocytes which are sensitized to antigens presented on the liver cell surface to form the immunologic synapse. The cytoplasm is taken up by the T cell and digested by the lysosome in the lymphocyte.

Improved Assessment of Pathological Regurgitation in Patients with Prosthetic Heart Valves by Multiplane Transesophageal Echocardiography.

The aim of this study was to evaluate the diagnostic increment of individually optimized axes in the assessment of pathological prosthetic valve regurgitation. Forty-two patients with pathologically regurgitant prostheses in the aortic (n = 21), mitral (n = 15), and tricuspid (n = 6) positions were examined by multiplane transesophageal echocardiography. The investigation was performed utilizing the transverse axis first, the longitudinal axis second, and the intermediate axes afterwards.

Alveolar and tissue surfactant pool sizes in humans.

The amounts of surfactant in human lung tissue and in the alveolar pool have not been extensively reported. We used 24 human lungs from persons over the age range of 13 mo to 80 yr to investigate whether the amount of saturated phosphatidylcholine (Sat-PC) in the human lung changed with age. Lung lavages also were obtained from 10 lungs at autopsy for measurements of the alveolar Sat-PC and surfactant protein-A (SP-A) concentrations.
