The objective of this study was to examine clinicians' patient selection and result interpretation of a clinically validated mass spectrometry test measuring amyloid beta and ApoE blood biomarkers combined with patient age (PrecivityAD® blood test) in symptomatic patients evaluated for Alzheimer's disease (AD) or other causes of cognitive decline. The Quality Improvement and Clinical Utility PrecivityAD Clinician Survey (QUIP I, ClinicalTrials.gov Identifier: NCT05477056) was a prospective, single-arm cohort study among 366 patients evaluated by neurologists and other cognitive specialists. Participants underwent blood biomarker testing and received an amyloid probability score (APS), indicating the likelihood of a positive result on an amyloid positron emission tomography (PET) scan. The primary study outcomes were appropriateness of patient selection as well as result interpretation associated with PrecivityAD blood testing. A 95% (347/366) concordance rate was noted between clinicians' patient selection and the test's intended use criteria. In the final analysis including these 347 patients (median age 75 years, 56% women), prespecified test result categories incorporated 133 (38%) low APS, 162 (47%) high APS, and 52 (15%) intermediate APS patients. Clinicians' pretest and posttest AD diagnosis probability changed from 58% to 23% in low APS patients and 71% to 89% in high APS patients (p < 0.0001). Anti-AD drug therapy decreased by 46% in low APS patients (p < 0.0001) and increased by 57% in high APS patients (p < 0.0001). These findings demonstrate the clinical utility of the PrecivityAD blood test in clinical care and may have added relevance as new AD therapies are introduced.

Objectives To assess the safety, tolerability, and key pharmacodynamic effects of subcutaneous batoclimab, a fully human anti‐neonatal Fc receptor monoclonal antibody, in patients with generalized myasthenia gravis and anti‐acetylcholine receptor antibodies. Methods A Phase 2a, proof‐of‐concept, randomized, double‐blind, placebo‐controlled trial is described. Eligible patients were randomized (1:1:1) to receive once‐weekly subcutaneous injections of batoclimab 340 mg, batoclimab 680 mg, or matching placebo for 6 weeks. Subsequently, all patients could enter an open‐label extension study where they received batoclimab 340 mg once every 2 weeks for 6 weeks. Primary endpoints were safety, tolerability, and change from baseline in total immunoglobulin G, immunoglobulin G subclasses, and anti‐acetylcholine receptor antibodies at 6 weeks post‐baseline. Secondary endpoints included changes from baseline to 6 weeks post‐baseline for Myasthenia Gravis Activities of Daily Living, Quantitative Myasthenia Gravis, Myasthenia Gravis Composite, and revised 15‐item Myasthenia Gravis Quality of Life scores. Results Seventeen patients were randomized to batoclimab 680 mg (n = 6), batoclimab 340 mg (n = 5), or placebo (n = 6). Batoclimab was associated with significantly greater reductions in total immunoglobulin G and anti‐acetylcholine receptor antibodies from baseline to 6 weeks post‐baseline than placebo. Reductions in immunoglobulin G subclasses were generally consistent with total immunoglobulin G. While clinical measures showed directionally favorable improvements over time, the study was not powered to draw conclusions about therapeutic efficacy. No safety issues were identified. Interpretation The safety profile, pharmacodynamics, and preliminary clinical benefits observed in this study support further investigation of subcutaneous batoclimab injections as a potential patient‐administered therapy for seropositive generalized myasthenia gravis.

[...] the lack of progress towards a final political solution and the continuing expansion of Israeli settlements on West Bank land have also led to the domestic weakening of the Palestinian Authority's power base. [...] the continuing Israeli occupation of Palestinian land and the ensuing inability of the Palestinian Authority to provide human security and a just peace to Palestinians undermine Palestinian rule of law, including the application of reform measures. * Rita Giacaman, Yoke Rabaia, Viet Nguyen-Gillham rita@birzeit.edu Institute of Community and Public Health, Birzeit University, Box 14, Birzeit, Occupied Palestinian Territory 1 Garcia-Moreno C, Jansen HAFM, Ellsberg M, Heise L, Watts CH, on behalf of the WHO Multicountry Study on Women's Health and Domestic Violence against Women Study Team.

After a full year of recording the performances of the different cool roofs and different-depth green roofs, we found that the green roofs performed better than the white cool roof with regard to cooling. But because of the amount of insulation, the thermal load due to the roof was negligible between the cool white roof and the green roof. That said, we would always recommend a green roof if budget or structure allowed.
