Bioethics in Medical Care Rationing During the Coronavirus Disease-19 Pandemic.

Background: Coronavirus (CoV) disease (COVID)-19 poses difficult situations in which the ethical course of action is not clear, or choices are made between equally unacceptable responses.

Methods: A web search was performed using the terms "bioethics; COVID-19; ethics; severe acute respiratory syndrome CoV-2; emergent care; pandemic; and public health emergencies."

Results: Protection from COVID-19 has resulted in the cancellation of necessary medical interventions, lengthened suffering, and potential non-COVID-19 deaths.

Prevalence of thyroid dysfunction in healthy adults according to the estimated iodine intake in 24-hour urine samples: The SALMEX cohort.

Purpose: The aim of this study was to evaluate the prevalence of thyroid dysfunction in a cohort of healthy individuals in Mexico City, as well as to investigate the potential associations of these results with their estimated iodine intake (EII) as reflected by their 24-hour urinary iodine excretion (24-h UIE).

Methods: From the SALMEX cohort, 683 adults provided an appropriate 24-h urine sample. Thyroid function tests and thyroid antibody concentrations were determined in the participants' sera.

Tocilizumab in glucocorticoid-resistant graves orbitopathy. A case series report of a mexican population.

Purpose: To describe pre- to post-treatment changes in clinical activity score (CAS) and exophthalmometry in patients with Graves orbitopathy treated with tocilizumab (TCZ).

Material And Methods: Eight Mexican patients presenting with active Graves orbitopathy (CAS>3/7) previously treated with glucocorticoids received 1 monthly dose of TCZ for 6 months. CAS, EUGOGO severity assessment and exophthalmometry were used to evaluate clinical status, with serum measurement of thyroid-stimulating hormone receptor antibodies (TR-Ab) for biochemical evaluation before and after application of TCZ.

Recurrent Papillary Thyroid Carcinoma to the Cervical Lymph Nodes: Outcomes of Compartment-Oriented Lymph Node Resection.

Introduction: Recurrence of papillary thyroid carcinoma after initial treatment is challenging. Surgical reintervention is recommended, but cure after surgery in uncertain and surgical morbidity may be high. This study evaluates the effect of compartment-oriented lymph node dissection (LND) on clinical and biochemical cure rate as well as the related complications.

Clinical utility of an ultrasensitive thyroglobulin assay in the follow-up of patients with differentiated thyroid cancer: can the stimulation test be avoided in patients with an intermediate recurrence risk?

Serum thyroglobulin (Tg) measurement during suppression with levothyroxine (LT4) using an ultrasensitive assay (OnT4-Tg) has been proposed as a replacement of TSH-stimulated Tg measurement (OffT4-Tg) in management of patients with differentiated thyroid cancer (DTC). The aim of this study is to evaluate the capacity of an ultrasensitive Tg assay in predicting an OffT4-Tg > 2.0 ng/mL based on the OnT4-Tg in patients with DTC and an intermediate recurrence risk.
