Autoimmune hemolytic anemia during pregnancy and puerperium: an international multicenter experience.

Relapsing or occurring de novo autoimmune hemolytic anemia (AIHA) during pregnancy or puerperium is a poorly described condition. Here, we report 45 pregnancies in 33 women evaluated at 12 centers from 1997 to 2022. Among the 20 women diagnosed with AIHA before pregnancy, 10 had a relapse.

Facing the Unknown: Idiopathic Giant Cell Hepatitis.

Giant cell hepatitis is a rare infiltrative disease associated with several viruses, drugs, malignancies, and autoimmune conditions. To date, treatment aims at controlling the underlying etiology, and there are limited data on the clinical course and treatment of idiopathic cases. We present a case of idiopathic giant cell hepatitis in an otherwise healthy adult man and review the literature regarding treatment and outcomes in this population.

Multiple Prior Live Births Are Associated With Cardiac Remodeling and Heart Failure Risk in Women.

Objective: Greater parity has been associated with cardiovascular disease risk. We sought to find whether the effects on cardiac remodeling and heart failure risk are clear.

Methods: We examined the association of number of live births with echocardiographic measures of cardiac structure and function in participants of the Framingham Heart Study (FHS) using multivariable linear regression.

Comparing self-reported obstructive airway disease in firefighters with and without World Trade Center exposure.

Background: The degree to which routine, non-World Trade Center (WTC) firefighting exposures contribute to the WTC exposure-obstructive airway disease (OAD) relationship is unknown. Our objective was to compare the frequency of self-reported OAD diagnoses in WTC-exposed firefighters from the Fire Department of the City of New York (FDNY) compared with non-WTC-exposed firefighters from other cities and the general population.

Methods: A total of 9792 WTC-exposed male FDNY firefighters and 3138 non-WTC-exposed male firefighters from Chicago, Philadelphia, and San Francisco who were actively employed on 9/11/01 and completed a health questionnaire were included.

DNA polymerase θ protects leukemia cells from metabolically induced DNA damage.

Leukemia cells accumulate DNA damage, but altered DNA repair mechanisms protect them from apoptosis. We showed here that formaldehyde generated by serine/1-carbon cycle metabolism contributed to the accumulation of toxic DNA-protein crosslinks (DPCs) in leukemia cells, especially in driver clones harboring oncogenic tyrosine kinases (OTKs: FLT3(internal tandem duplication [ITD]), JAK2(V617F), BCR-ABL1). To counteract this effect, OTKs enhanced the expression of DNA polymerase theta (POLθ) via ERK1/2 serine/threonine kinase-dependent inhibition of c-CBL E3 ligase-mediated ubiquitination of POLθ and its proteasomal degradation.

Polypharmacy and Multimorbidity in the Urogynecology Population and Their Effect on Pelvic Floor Symptoms.

Importance: Polypharmacy and multimorbidity are common in older adults but has not been well studied in the urogynecologic patient population.

Objectives: The objective of this study was to determine the prevalence of polypharmacy and multimorbidity in a diverse outpatient urogynecologic population and to examine whether polypharmacy and/or multimorbidity were associated with lower urinary tract symptoms, pelvic organ prolapse, defecatory distress, and/or female sexual dysfunction.

Study Design: This is a secondary analysis of a dual-center cross-sectional study of new patients presenting for evaluation of pelvic floor disorders at 2 urban academic outpatient urogynecology clinics.

Outcomes after a Uterine-Sparing Approach to Essure Contraceptive Device Removal.

Background And Objective: To analyze long-term effectiveness of a conservative, uterine-sparing approach to laparoscopic Essure removal. Specific outcomes of interest include patient satisfaction, symptom resolution, and subsequent surgical intervention.

Methods: A retrospective case series and follow-up survey.

Abortion policy implementation in Ireland: successes and challenges in the establishment of hospital-based services.

Objective: To describe successes and highlight remaining challenges in the establishment of hospital-based abortion services after legal change in the Republic of Ireland.

Methods: We conducted a mixed-methods study on the implementation of abortion policy in Ireland. In this manuscript, we present the results from a qualitative analysis of in-depth interviews conducted with hospital-based providers, service users, and key informants.

Blood Pressure Classification Status in Children With CKD Following Adoption of the 2017 American Academy of Pediatrics Guideline.

Rationale & Objective: Accurate detection of hypertension is crucial for clinical management of pediatric chronic kidney disease (CKD). The 2017 American Academy of Pediatrics (AAP) clinical practice guideline for childhood hypertension included new normative blood pressure (BP) values and revised definitions of BP categories. In this study, we examined the effect of applying the AAP guideline's normative data and definitions to the Chronic Kidney Disease in Children (CKiD) cohort compared with use of normative data and definitions from the 2004 Fourth Report on the Diagnosis, Evaluation, and Treatment of High Blood Pressure in Children and Adolescents.

Ablation of atrial fibrillation beyond pulmonary vein isolation: Do additional ablation lesions impact left atrial function?

Introduction: Electrical isolation of pulmonary veins (PVI) is a cornerstone for atrial fibrillation (AF) ablation. The overall effect of AF ablation, and especially lesions beyond PVI, on left atrial (LA) function is currently poorly understood. Our aim was to determine if LA function is different in patients after extensive LA ablation compared to PVI only.

The relationship between fecal incontinence and food insecurity in United States women: an analysis of 2005-2010 National Health and Nutrition Examination Survey.

Background: Fecal incontinence is a prevalent debilitating pelvic floor disorder characterized by the involuntary loss of stool. Fecal incontinence is known to be associated with constipation and loose stool, advancing age, chronic comorbidities, and previous anorectal trauma, among other biologic risk factors. The relationship between social determinants of health, such as food insecurity, and fecal incontinence is not well elucidated.

PGT-A is associated with reduced cumulative live birth rate in first reported IVF stimulation cycles age ≤ 40: an analysis of 133,494 autologous cycles reported to SART CORS.

Purpose: To evaluate the impact of preimplantation genetic testing for aneuploidy (PGT-A) on cumulative live birth rate (CLBR) in IVF cycles.

Methods: Retrospective cohort study of the SART CORS database, comparing CLBR for patients using autologous oocytes, with or without PGT-A. The first reported autologous ovarian stimulation cycle per patient between January 1, 2014, and December 31, 2015, and all linked embryo transfer cycles between January 1, 2014, and December 31, 2016, were included in the study.

Oncocytic Cell Carcinoma of the Thyroid: A Case Report and an Overview of the Diagnosis, Treatment Modalities, and Prognosis.

Cancers of the thyroid gland are uncommon, accounting for 1% of malignant tumors. Oncocytic carcinoma of the thyroid (OCA), previously known as "Hürthle cell" carcinomas, make up 3% to 5% of all thyroid cancers and are extremely rare. In the United States, the incidence of thyroid cancer is approximately 12 per 100,000 per year and increases with age.

Intravital imaging to study cancer progression and metastasis.

Navigation through the bulk tumour, entry into the blood vasculature, survival in the circulation, exit at distant sites and resumption of proliferation are all steps necessary for tumour cells to successfully metastasize. The ability of tumour cells to complete these steps is highly dependent on the timing and sequence of the interactions that these cells have with the tumour microenvironment (TME), including stromal cells, the extracellular matrix and soluble factors. The TME thus plays a major role in determining the overall metastatic phenotype of tumours.

Patient-centred models of hepatitis C treatment for people who inject drugs: a multicentre, pragmatic randomised trial.

Background: To achieve WHO targets for the elimination of hepatitis C virus (HCV) as a public threat, an increased uptake of HCV treatment among people who inject drugs (PWID) is urgently needed. Optimal HCV co-located treatment models for PWID have not yet been identified. We aimed to compare two patient-centred models of HCV care in PWID with active drug use.

Association of Hydroxychloroquine Dose With Adverse Cardiac Events in Patients With Systemic Lupus Erythematosus.

Objective: To determine whether hydroxychloroquine (HCQ) dose is associated with adverse cardiac outcomes in patients with systemic lupus erythematosus (SLE).

Methods: Patients with SLE taking HCQ and with ≥1 echocardiogram followed at a tertiary care center in the Bronx, New York between 2005 and 2021 were included. The HCQ weight-based dose at the HCQ start date was the main exposure of interest.

Periprocedural P2Y inhibitors improve perioperative outcomes after carotid stenting by primarily decreasing strokes.

Objective: The continuation of antiplatelet agents in the periprocedural period around carotid stenting (CAS) procedures is felt to be mandatory to minimize the risk of periprocedural stroke. However, the optimal antiplatelet regimen is unclear, with some advocating dual antiplatelet therapy, and others supporting the use of P2Y inhibitors alone. The objective of this study was to evaluate the periprocedural effect of P2Y inhibitors for CAS.
