Objective: Approximately, 2% of women who undergo chorionic villi sampling (CVS) will subsequently undergo amniocentesis due to placental mosaicism or sampling/laboratory issues. Our objective was to compare obstetric outcomes in women who underwent both procedures with those who had CVS alone.
Study Design: Retrospective case-control study of patients with singleton pregnancies undergoing invasive testing from 2010 to 2020 was performed. All women who underwent CVS followed by amniocentesis were compared with a control group who underwent CVS alone matched (2:1) for age and year of pregnancy. Women with pregnancy loss at <16 weeks were excluded from the control group. Pregnancies terminated for genetic abnormalities were excluded. Obstetric outcomes were compared between cases and controls. Student -test and Fisher's exact test were used for statistical comparison.
Results: During the study period 2,539 women underwent CVS, and 66 (2.6%) subsequently underwent amniocentesis. The 66 cases were compared with 132 age-matched controls who underwent CVS alone. Mean maternal age was 36.8 ± 3.4 years, and 43% of women were nulliparous. Amniocentesis was performed due to sampling or laboratory issues in 33% of cases, placental mosaicism in 44%, and further diagnostic testing in 23%. There were no pregnancy losses or stillbirths in either group. Those who had two invasive procedures delivered at similar gestational ages and birthweights and did not have higher rates of adverse outcomes compared with those who underwent CVS alone.
Conclusion: Patients considering CVS who are concerned about the possibility that a second invasive procedure could be required should be reassured that this does not appear to be associated with higher rates of adverse outcomes. Due to study size, we cannot exclude the possibility of small differences in uncommon outcomes, such as pregnancy loss or stillbirth.
Key Points: · Amniocentesis may be recommended after CVS due to mosaicism, sampling issues, or further testing.. · Amniocentesis after CVS is not associated with pregnancy loss or other adverse outcomes compared.. · Patients who have both CVS and amniocentesis deliver at similar gestational ages and birthweights..

A 36-year-old woman diagnosed with complicated cholecystolithiasis underwent elective laparoscopic cholecystectomy (LC), then converted to open cholecystectomy because of a massive intraoperative bleeding. Hemostasis was performed with clipping and suturing the source of bleeding. In post-operative period, the patient suffered from persistent anemia associated with hemoperitoneum diagnosed through abdominal CT scanning, in absence of any sign of active bleeding.

Background: Growth differentiation factor (GDF)-15 is a pleiotropic cytokine that is associated with appetite-suppressing effects and weight loss in patients with malignancy.
Objectives: This study aims to investigate the relationships between GDF-15 levels, anorexia, cachexia, and clinical outcomes in patients with advanced heart failure with reduced ejection fraction (HFrEF).
Methods: In this observational, retrospective analysis, a total of 344 patients with advanced HFrEF (age 58 ± 10 years, 85% male, 67% NYHA functional class III), underwent clinical and echocardiographic examination, body composition evaluation by skinfolds and dual-energy x-ray absorptiometry, circulating metabolite assessment, Minnesota Living with Heart Failure Questionnaire, and right heart catheterization.
Incidence and Prognosis of Prosthesis-Patient Mismatch After Transcatheter Aortic Valve Replacement for Bicuspid Aortic Stenosis.

Department of Cardiology, Keio University School of Medicine, Tokyo, Japan.
Background: Evidence regarding the incidence of prosthesis-patient mismatch (PPM) and long-term mortality after transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valve stenosis (AS) is scarce.
Objectives: This study sought to assess the incidence and prognostic impact of PPM after TAVR for bicuspid AS compared with that for tricuspid AS.
Methods: In total, 7,393 patients who underwent TAVR were prospectively enrolled in the OCEAN-TAVI (Optimized Catheter Valvular Intervention Transcatheter Aortic Valve Implantation) registry, an ongoing Japanese, multicenter registry.

Background: Cataract surgery is the most common surgical procedure performed for older US adults. Cataracts are associated with poor cognition and higher rates of dementia, but whether cataract surgery improves cognition for US older adults is not known. We examined the relationship between cataract surgery and long-term change in cognition in the Health and Retirement Study, a population-based study of older US adults linked with Medicare billing data.
