The utility of intraoperative PTH dosage in primary hyperparathyroidism based on preoperative diagnosis and surgical choice.

Background: The aim of this study was to evaluate the impact of the intraoperative PTH (ioPTH) monitoring in the success of parathyroidectomy based on the concordant or indeterminate preoperative imaging studies of localization and the performed surgical choices.

Methods: Fourthy-seven patients who received parathyroidectomy operations were divided in four groups: concordance of the imaging and ioPTH, concordance of the imaging and no ioPTH, indeterminate imaging and ioPTH and indeterminate imaging and no ioPTH.

Results: Overall, patients in whom ioPTH monitoring was not performed were healed in 89.

Dione's Wispy Terrain: A Cryovolcanic Story?

We examine the HO ice phase on the surface of Dione, one of Saturn's icy satellites, to investigate whether it might harbor cryovolcanic activity induced by a subcrustal body of water. Several studies have searched for such a signature, as summarized in Buratti et al.; however, none has yet produced sufficient evidence to dissipate doubts.

Well-described exercises for chronic low back pain in Life Science Literature: A systematic review.

Background: Therapeutic exercise (TE) is recommended in multimodal treatment for patients with non-specific chronic back pain (cLBP).

Objective: The aim of this study is to identify an exercise or a spectrum of exercises, well described and reproducible by the clinician, for cLBP patients.

Methods: Systematic review by researching in the databases MEDLINE, EMBASE, PEDro, CINAHL, and Scopus.

Color, composition, and thermal environment of Kuiper Belt object (486958) Arrokoth.

The outer Solar System object (486958) Arrokoth (provisional designation 2014 MU) has been largely undisturbed since its formation. We studied its surface composition using data collected by the New Horizons spacecraft. Methanol ice is present along with organic material, which may have formed through irradiation of simple molecules.

Detection of ammonia on Pluto's surface in a region of geologically recent tectonism.

We report the detection of ammonia (NH) on Pluto's surface in spectral images obtained with the New Horizons spacecraft that show absorption bands at 1.65 and 2.2 μm.
