Bibliometric Analysis of the Composition of Landmark Cerebral Venous Sinus Thrombosis Research.

Background: Cerebral Venous Sinus Thrombosis (CVST) is a relatively rare type of stroke, accounting for less than 3% of all stroke cases, and is associated with significant morbidity and mortality in young females. However, when promptly diagnosed and treated, it can have favorable outcomes. Several knowledge gaps remain regarding pathophysiology, diagnosis, and management of CVST, so critical assessment of past and present research could help close these gaps or establish targeted future research goals.

Parathyroid allotransplantation for severe post-surgical hypoparathyroidism: a Brazilian experience.

This study presents the cases of two women who developed severe permanent hypoparathyroidism after neck surgery for papillary thyroid cancer and underwent parathyroid allotransplantation. Despite taking high doses of calcium and calcitriol supplements, the patients experienced persistent hypocalcemic symptoms. Fresh parathyroid tissue was removed and prepared from two patients with hyperparathyroidism secondary to end-stage kidney disease and was implanted in the non-dominant forearm of the recipients.

Real-time prediction of dissolution profiles of coated oral dosage forms.

Optical coherence tomography (OCT) has emerged as an in-line monitoring technique for pharmaceutical coating processes based on a representative number of samples. In this study, an approach was developed to correlate the coating thickness measured in-line via OCT with the resultant tablet dissolution profile. This strategy enables prediction of the dissolution profile of coated oral dosage forms for each individual state of the coating process in real-time.

The comparison of melt technologies based on mesoporous carriers for improved carvedilol dissolution.

High-shear (HS) melt granulation and hot melt extrusion (HME) were compared as perspective melt-based technologies for preparation of amorphous solid dispersions (ASDs). ASDs were prepared using mesoporous carriers (Syloid 244FP or Neusilin US2), which were loaded with carvedilol dispersed in polymeric matrix (polyethylene glycol 6000 or Soluplus). Formulations with high carvedilol content were obtained either by HME (11 extrudates with polymer:carrier ratio 1:1) or HS granulation (6 granulates with polymer:carrier ratio 3:1).

Osteoporosis in Parkinson's disease and the role of lean body mass: a cross-sectional study in a Brazilian tertiary center.

Background: Parkinson's disease (PD) is the second most common neurodegenerative illness and has the highest increase rate in recent years. There is growing evidence to suggest that PD is linked to higher osteoporosis rates and risk of fractures.

Objective: This study aims to estimate the prevalence and factors associated with osteoporosis as defined by the National Osteoporosis Foundation (NOF) and World Health Organization in patients with mild to moderate PD.
