Published: September 2009

This article summarizes the ontogenesis and genetics of the thyroid with regards to its possible congenital dysfunction and briefly refers to the roles of the mother-placenta-fetal unit, iodine effect, and organic and functional changes of the negative feedback mechanism, as well as maturity and illness, in some forms of congenital hypo- and hyperthyroidism. This article also describes the published literature and the authors' data on the clinical aspects of congenital hypothyroidism, on the alternating hypo- and hyperthyroidism in the neonatal period, and on neonatal hyperthyroidism.

Division of Gastroenterology, Hepatology and Endoscopy, Brigham and Women's Hospital, 75 Francis Street, Boston, MA, 02115, USA.

Background: Chronic constipation, diarrhea, and fecal incontinence (FI) are prevalent with significant impact on quality of life and healthcare utilization. Thyroid dysfunction was recognized as a potential contributor to bowel disturbances in selected populations, but the strength/consistency of this association remain unclear.

Aims: To investigate the relationship between thyroid function and bowel health measures (constipation, diarrhea, and FI) in a nationally representative sample of the U.

Purpose: To determine the reference values for the shock index (SI) in postpartum patients undergoing elective cesarean delivery with regional anesthesia.

Methods: This prospective study was conducted at our tertiary center between August 1, 2023, and March 1, 2024. We calculated the reference values for the SI within the first 48 h postpartum for patients who underwent elective cesarean delivery after the 34th week of gestation.

Article Synopsis
  • A study in Denmark investigated how thyroid dysfunction impacts heart failure (HF) outcomes in patients diagnosed with HF between 2000 and 2021.
  • The research categorized patients based on thyroid function and found that those with both hypo- and hyperthyroidism had higher risks of mortality and hospitalization compared to those with normal thyroid function.
  • The findings highlight the need for healthcare providers to be more aware of the risks associated with thyroid issues in patients at risk for heart failure.

Underlying disease risk among patients with fatigue: a population-based cohort study in primary care.

Br J Gen Pract

December 2024

Epidemiology of Cancer Healthcare and Outcomes (ECHO) Research Group, Department of Behavioural Science and Health, Institute of Epidemiology & Health Care, University College London, London, UK.

Background: Presenting to primary care with fatigue is associated with a wide range of conditions, including cancer, although their relative likelihood is unknown.

Aim: To quantify associations between new-onset fatigue presentation and subsequent diagnosis of various diseases, including cancer.

Design And Setting: A cohort study of patients presenting in English primary care with new-onset fatigue during 2007-2017 (the fatigue group) compared with patients who presented without fatigue (the non-fatigue group), using Clinical Practice Research Datalink data linked to hospital episodes and national cancer registration data.

Introduction: Thyroid dysfunction is prevalent in chronic kidney disease (CKD) patients and significantly impacts renal outcomes and mortality. This study investigated the associations between thyroid function and clinical outcomes, and also the therapeutic effects of thyroid hormone replacement therapy (THRT) in CKD patients.

Methods: We conducted a retrospective cohort study using data from the China Renal Data System.
