Prognostic scores for predicting overall survival in patients with metastatic renal and urothelial cancer undergoing immunotherapy - which one to use?

Purpose: Evaluation of the prognostic significance of four different scoring systems in a real-world cohort of patients with metastatic urothelial carcinoma (mUC) or renal cell carcinoma (mRCC) undergoing immunotherapy (IO).

Methods: For 120 patients with mUC (n = 67) and mRCC (n = 53) who received IO between July 2016 and December 2020 at the tertiary Urological University Medical Centre Mannheim, the following scores were recorded at pre-treatment baseline: modified Glasgow prognostic score (mGPS), systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), neutrophil-to-eosinophil ratio (NER). Overall survival (time between the beginning of IO until the patients' death or last contact) was determined for every patient.

Impact of a kidney-adjusted ERAS protocol on postoperative outcomes in patients undergoing partial nephrectomy.

Purpose: Evaluation of a kidney-adjusted enhanced recovery after surgery (ERAS) protocol (kERAS) in patients undergoing nephron-sparing surgery (PN).

Dusk-Dawn Asymmetries in SuperDARN Convection Maps.

The Super Dual Auroral Radar Network (SuperDARN) is a collection of radars built to study ionospheric convection. We use a 7-year archive of SuperDARN convection maps, processed in 3 different ways, to build a statistical understanding of dusk-dawn asymmetries in the convection patterns. We find that the data set processing alone can introduce a bias which manifests itself in dusk-dawn asymmetries.

[Promoting women in urology using the example of habilitation].

Background: The proportion of female urologists is steadily increasing, yet they continue to be underrepresented in academic leadership positions. A postdoctoral lecture qualification (habilitation), which is mandatory for a successful scientific career, is achieved significantly less often by female urologists in Germany than by their male colleagues.

Objective: To identify factors to effectively promote female urologists into academic leadership positions, the current situation, as well as factors influencing successful habilitation of women who are members of the German Society of Urology (Deutsche Gesellschaft für Urologie [DGU]) were investigated.

Baseline Modified Glasgow Prognostic Score (mGPS) Predicts Radiologic Response and Overall Survival in Metastatic Hormone-sensitive Prostate Cancer Treated With Docetaxel Chemotherapy.

Purpose: A symptomatic pseudoaneurysm (SPA) is a rare but severe complication after partial nephrectomy (PN). Selective trans-arterial embolization (TAE) is the treatment of choice with high success rates. However, the influence of this intervention on postsurgical renal function has not been studied.

Nigral stimulation for resistant axial motor impairment in Parkinson's disease? A randomized controlled trial.

Gait and balance disturbances typically emerge in advanced Parkinson's disease with generally limited response to dopaminergic medication and subthalamic nucleus deep brain stimulation. Therefore, advanced programming with interleaved pulses was put forward to introduce concomittant nigral stimulation on caudal contacts of a subthalamic lead. Here, we hypothesized that the combined stimulation of subthalamic nucleus and substantia nigra pars reticulata improves axial symptoms compared with standard subthalamic nucleus stimulation.

Computer control of carbon-nitrogen ratio in Spirulina platensis.

An on-line computer was used to control the ratio of carbon to nitrogen in algal biomass. An indirect method of growth and biomass estimation was utilized. This was based on balancing the amount of CO(2) carbon in and out of the algal bioreactor.

Biomass yields of Chlorella from iron (Yx/Fe) in iron-limited batch cultures.

The maximum biomass in iron-limited photosynthetic batch cultures of chlorella increased as the logarithm of the iron concentration. The growth yield from iron (UxFe) showed a marked inverse relation to the specific growth rate. The maximum biomass yield, g dry biomass/g iron consumed, was 7.
