Since screening and diagnostic tests for dementia do not have perfect accuracy, >1 test is often administered when assessing patients with cognitive complaints. Use of both patient performance tests and informant questionnaires has been recommended. Combination of individual test results may be based on methods originally defined by Thomas Bayes (revision or updating of pretest probabilities to post-test probabilities given the test results) and by George Boole (application of associative "AND" or "OR" operator). This study sought to apply these methods in clinical practice.
Using the dataset of a pragmatic test accuracy study of the Six-Item Cognitive Impairment Test (6CIT) and informant Ascertain Dementia 8 (AD8), post-test probabilities for the combination were calculated using Bayes' formula and compared to Boolean "AND" combination. Combined test sensitivity and specificity was calculated using either Boolean "AND" or "OR" operator and compared to results using equations based on individual test sensitivity and specificity.
Both Bayesian and Boolean methods produced similar improvements from pretest probability (0.288) to combined post-test probability for dementia (≈0.5). Likewise, the 2 different methods for calculating combined sensitivities and specificities gave similar results, with, as anticipated, the "AND" combination improving overall specificity (to ≈0.65) whereas the "OR" combination improved sensitivity (to ≈1.00).
Combination of individual screening test results using Bayesian and Boolean methods is relatively straightforward and may add to clinicians' intuitive judgements when combining test results.

Older cancer patients with locally advanced or metastatic disease may benefit from chemotherapy alone or combined with radiotherapy. However, chemotherapy is often omitted either because of physician bias or because of its underlying comorbidity, thus compromising their survival. The coronavirus disease 19 (COVID-19) pandemic is compounding this issue because of the fear of immunosuppression induced by chemotherapy on the elderly which makes them more vulnerable to the virus.
Immunotherapy has less effect on the patient bone marrow compared to chemotherapy. The potential synergy between radiotherapy and immunotherapy may improve local control and survival for older patients with selected cancer. Preliminary data are encouraging because of better survival and local control in diseases which are traditionally resistant to radiotherapy and chemotherapy such as melanoma and renal cell carcinoma. selleck compound Key Message We propose a new paradigm combining immunotherapy at a reduced dose and/or extended dosing intervals and hypofractionated radiotherapy for older patients with selected cancer which needs to be tested in future clinical trials.

Intraspinal epidermoid cysts are congenital or acquired in origin; whereas intraspinal neurenteric cysts (NECs) are of congenital origin. Their individual association with spinal dysraphism and vertebral segmentation anomalies is very well known.
We hereby report a case of concurrent intradural extramedullary epidermoid and NEC at adjacent vertebral levels in a spinal dysraphism child, not reported in English Literature till now.
Multiple spinal lesions related to any/all of the 3 germ layers can coexist at same or adjacent vertebral levels in the same patient and surgical planning shown to be done accordingly.

The sequencing-based noninvasive prenatal testing (NIPT) has been successfully integrated into clinical practice and facilitated the early detection of fetal chromosomal anomalies. However, a comprehensive reference material to evaluate and quality control NIPT services from different NIPT providers remains unavailable.
In this study, we established a set of NIPT reference material consisting of 192 simulated samples. Most of the potential factors influencing the accuracy of NIPT, such as fetal fraction, mosaicism, and interfering substances, were included in the reference material. We compared the performance of chromosomal abnormalities detection on 3 widely used sequencers (NextSeq 500, BGISEQ-500, and Ion Proton) based on the reference material.
All 3 sequencers provided highly accurate and reliable results to samples with ≥3.5% fetal fractions and high percentage of mosaicism.
The established reference material can serve as a universal standard quality control for the current and new-coming NIPT providers based on various sequencers.

While biographers have described him as Republican, anticlerical, and agnostic, the literature also presents evidence that he came to admire Buddhism toward the end of his life; Charcot's involvement with numerous patients suffering from incurable and insidious neurological diseases may have contributed to this change in attitude.
