Mental health experiences of HIV/TB healthcare workers during the COVID-19 pandemic - lessons for provider well-being and support from a qualitative study in seven South African provinces.

Background: COVID-19 has substantially reshaped health service delivery. Healthcare workers have had to serve more clients, work longer shifts, and operate in conditions of uncertainty. They have experienced multiple stressors related to the additional 'labour of care', including managing the frustration of inadequate therapeutic or symptom relief options, witnessing clients dying, and having to give this news to clients' family members.

An interdisciplinary team-training protocol for robotic gynecologic surgery improves operating time and costs: analysis of a 4-year experience in a university hospital setting.

Main aim of this study is to assess the effect of a structured, interdisciplinary, surgical, team-training protocol in robotic gynecologic surgery, with the gradual integration of an advanced nurse practitioner. Data from all robotic surgical procedures were prospectively acquired. The surgical team consisted of one experienced surgeon and two surgical fellows and the scrub nurse team from three advance nurse practitioners, specialized in robotic surgery.

KRAS mutation status is not predictive for objective response to anti-EGFR treatment with erlotinib in patients with advanced pancreatic cancer.

Background: It has not yet been defined if KRAS has a prognostic value or is a predictive biomarker for the efficacy of erlotinib in advanced pancreatic cancer (PC).

Methods: AIO-PK0104 was a phase III trial comparing gemcitabine/erlotinib followed by capecitabine with capecitabine/erlotinib followed by gemcitabine in advanced PC. For this post hoc subgroup analysis, biomarker data on the KRAS exon 2 mutation status were correlated with objective response to 1st-line therapy and with overall survival after start of 2nd-line chemotherapy (OSc).

EGFR pathway biomarkers in erlotinib-treated patients with advanced pancreatic cancer: translational results from the randomised, crossover phase 3 trial AIO-PK0104.

Background: We aimed to identify molecular epidermal growth factor receptor (EGFR) tissue biomarkers in pancreatic cancer (PC) patients treated with the anti-EGFR agent erlotinib within the phase 3 randomised AIO-PK0104 study.

Methods: AIO-PK0104 was a multicenter trial comparing gemcitabine/erlotinib followed by capecitabine with capecitabine/erlotinib followed by gemcitabine in advanced PC; primary study end point was the time-to-treatment failure after first- and second-line therapy (TTF2). Translational analyses were performed for KRAS exon 2 mutations, EGFR expression, PTEN expression, the EGFR intron 1 and exon 13 R497K polymorphism (PM).

EFNS guidelines on disease-specific CSF investigations.

We reviewed the literature for disease-specific markers in cerebrospinal fluid (CSF) and evaluated their diagnostic and prognostic relevance in neurological diseases. High tau protein in combination with low amyloid beta levels has a high sensitivity (80%) and specificity (90%) for Alzheimer's disease (AD) against normal aging and can predict conversion of mild cognitive impairment to AD. The detection of 14-3-3 has a high sensitivity (80-90%) and specificity (90%) for the diagnosis of CJD.
