Diagnostic Performance of Screening Tools for Depressive Symptoms in Vulnerable Older Patients with Cancer Undergoing Comprehensive Geriatric Assessment (CGA): Results from the SCREEN Pilot Study

Depression is a common and disabling disorder in later life, particularly among people with poor physical health. There are many screening tools available that can be used to examine depressive symptoms; however, not all of them may be appropriate or accurate for older adults with cancer. This pilot study was designed to test the diagnostic performance of two screening tools and their short versions in a cohort of vulnerable (G8 score ≤ 14/17) older patients with cancer undergoing comprehensive geriatric assessment (CGA). The prospective analysis covered 50 vulnerable patients with cancer aged ≥70 years. The diagnostic performance of the Geriatric Depression Scale (GDS)-15, GDS-4, Patient Health Questionnaire (PHQ)-9 and PHQ-2 was compared to the ‘gold standard’ Structured Clinical Interview for DSM-5 Disorders (SCID-5-S) depression module A. The sensitivity and specificity in detecting depressive symptoms were the highest in the case of PHQ-2, with an area under the receiver operating characteristic curve (AUROC) of 92.7%. The AUROC for the 9-item version, PHQ-9, was 90.2%. For the GDS-15 and GDS-4, the AUROC was only 56.2% and 62.0%, respectively. The SCREEN pilot study illustrates the potential benefit of using a shorter screening tool, PHQ-2, to identify older patients with cancer who would benefit from a more in-depth emotional evaluation as part of a CGA.</jats:p

Susceptibility of the dromedary (Camelus dromedarius) to rotavirus infection

Camelus dromedarius) is susceptible to rotavirus infection. Among 55 dromedary sera collected in Morocco, 27, it is to say about half of them, possessed anti-rotavirus antibodies. The dromedary is the refore susceptible to rotavirus infection, like many other animal species.Camelus dromedarius) est réceptif à l’infection par rotavirus. Sur 55 sérums de chamelons récoltés au Maroc, 27, soit la moitié à peu près, contenaient des anticorps dirigés contre ce virus. Le dromadaire est réceptif a l’infection par le rotavirus, comme la plupart des autres espèces animales

Lithographic process simulation for scanners

In scanner systems wafer and reticle move continuously with respect to the projection optics. This movement across image field results in varying lateral shift and focus positions and in an averaging of aberrations from different positions of the projection system. Several approaches for the effective simulation of these effects are discussed. Based on simulated and experimental data, scanner effects are quantified and compared to results of static stepper exposure
