Mixed stones: urinary stone composition, frequency and distribution by gender and age.

Proper analysis of urinary stone composition is a cornerstone for diagnosis, targeted treatment and recurrence prevention of urolithiasis. The aim of this study was to determine the composition, frequency and distribution of mixed stones according to gender and age of patients. A total of 42,519 urinary stones from 30,311 men and 12,208 women submitted between January 2007 and December 2020 were studied.

Urinary stone composition in Germany: results from 45,783 stone analyses.

Purpose: Stone composition can provide valuable information for the diagnosis, treatment and recurrence prevention of urolithiasis. The aim of this study was to evaluate the distribution of urinary stone components and the impact of different crystal forms according to gender and age of patients in Germany.

Methods: A total of 45,783 urinary stones submitted from 32,512 men and 13,271 women between January 2007 and December 2020 were analyzed by infrared spectroscopy.

Management of Metastatic Bone Disease Algorithms for Diagnostics and Treatment.

Background: Bone is a frequent site of metastases in advanced cancer and is associated with significant skeletal morbidity. Current treatment options are aimed at preserving and improving functional independence and quality of life.

Materials And Methods: A review of current literature focusing on diagnostic tools and treatment approaches of bone metastasis in advanced cancer was performed and conclusions were incorporated into diagnostic and treatment algorithms.

Zeolites X and A crystallization compared by simultaneous UV/VIS-Raman and X-ray diffraction.

The hydrothermal crystallizations of two zeolite topologies (FAU and LTA) have been studied by simultaneous UV-Raman spectroscopy and X-ray diffraction in a home built setup. A wide angle X-ray diffractometer has been redesigned and combined with Raman components. The results revealed, despite similar structures of the starting gels, different aluminosilicate species evolved in the two systems, prior to emerging Bragg scattering.

Improving Interoperability by Incorporating UnitsML Into Markup Languages.

Maintaining the integrity of analytical data over time is a challenge. Years ago, data were recorded on paper that was pasted directly into a laboratory notebook. The digital age has made maintaining the integrity of data harder.
