Levothyroxine-induced serum free thyroxine response following radioactive iodine administration in patients thyroidectomized for differentiated thyroid cancer: A randomized controlled trial.

Endocrine 2022 Jun 25. Epub 2022 Jun 25.

SSD Medicina interna ad indirizzo onco-endocrinologico, Università di Parma - Azienda Ospedaliero-Universitaria di Parma, Parma, Italy.

Purpose: Patients undergoing thyroidectomy for differentiated thyroid cancer (DTC) may require 131-radioactive iodine (RAI) administration for remnant ablation or disease treatment. After ingestion, RAI resides within the gastrointestinal tract potentially leading to mucosal damage and abnormalities in the absorption of levothyroxine (LT4). The aim of this study was to evaluate whether serum FT4 peak, induced by a LT4 challenge, changes according to the LT4 formulation (solid or liquid) in both RAI and non-RAI-treated DTC patients.

Estimands for factorial trials.

Stat Med 2022 Jun 25. Epub 2022 Jun 25.

MRC Clinical Trials Unit at UCL, London, UK.

Factorial trials offer an efficient method to evaluate multiple interventions in a single trial, however the use of additional treatments can obscure research objectives, leading to inappropriate analytical methods and interpretation of results. We define a set of estimands for factorial trials, and describe a framework for applying these estimands, with the aim of clarifying trial objectives and ensuring appropriate primary and sensitivity analyses are chosen. This framework is intended for use in factorial trials where the intent is to conduct "two-trials-in-one" (ie, to separately evaluate the effects of treatments A and B), and is comprised of four steps: (i) specifying how additional treatment(s) (eg, treatment B) will be handled in the estimand, and how intercurrent events affecting the additional treatment(s) will be handled; (ii) designating the appropriate factorial estimator as the primary analysis strategy; (iii) evaluating the interaction to assess the plausibility of the assumptions underpinning the factorial estimator; and (iv) performing a sensitivity analysis using an appropriate multiarm estimator to evaluate to what extent departures from the underlying assumption of no interaction may affect results.

Combined anterior and posterior ring fixation versus posterior ring fixation alone in the management of unstable Tile B and C pelvic ring injuries: A randomized controlled trial.

Chin J Traumatol 2022 Jun 15. Epub 2022 Jun 15.

Department of Orthopedics and Traumatology, Faculty of Medicine, Ain Shams University, Cairo, 11522, Egypt.

Purpose: Combined anterior and posterior ring (APR) fixation is classically performed in Tile B2 and C1 injuries to achieve superior biomechanical stability. However, the posterior ring (PR) is the main weight bearing portion that is responsible for weight transmission from the upper parts of the body to the lower limbs through the sacrum and the linea terminalis. It is hypothesized that isolated PR fixation can achieve comparable radiological and clinical outcomes to APR fixation. Read More

Impact of empathic physician contact on patient anxiety and distress during the waiting period after embryo transfer: a randomized controlled trial.

Reprod Biomed Online 2022 May 5. Epub 2022 May 5.

Department of Obstetrics and Gynecology, Beth Israel Deaconess Medical Center, Boston MA, USA; Department of Obstetrics, Gynecology and Reproductive Biology, Harvard Medical School, Boston MA, USA; Boston IVF/Eugin Group, Waltham MA, USA; Domar Center for Mind/Body Health, Boston IVF, Waltham MA, USA.

Research Question: Can an empathic physician phone call in the interval between embryo transfer and first serum human chorionic gonadotrophin measurement decrease anxiety and distress amongst patients undergoing IVF?

Design: This was a randomized controlled trial at a single academically-affiliated fertility centre including patients aged 18-43 undergoing their first embryo transfer with autologous fresh or euploid cryopreserved embryos following preimplantation genetic testing for aneuploidies (frozen embryo transfer, FET/PGT-A).
