Simultanagnosia is a disorder of visual attention resulting from bilateral parieto-occipital lesions. Healthy individuals look at eyes to infer people's attentional states, but simultanagnosics ...allocate abnormally few fixations to eyes in scenes. It is unclear why simultanagnosics fail to fixate eyes, but it might reflect that they are (a) unable to locate and fixate them, or (b) do not prioritize attentional states. We compared eye movements of simultanagnosic G.B. to those of healthy subjects viewing scenes normally or through a restricted window of vision. They described scenes and explicitly inferred attentional states of people in scenes. G.B. and subjects viewing scenes through a restricted window made few fixations on eyes when describing scenes, yet increased fixations on eyes when inferring attention. Thus G.B. understands that eyes are important for inferring attentional states and can exert top-down control to seek out and process the gaze of others when attentional states are of interest.
This prospective, cross-sectional study of HIV testing at two sexually transmitted infection clinics compares testing results from the ARCHITECT HIV Ag/Ab Combo fourth generation assay against the ...current standard of care in North Carolina (third generation enzyme immunoassay testing with western blot confirmation and reflex nucleic acid amplification testing of pooled seronegative samples). In this setting, the assay reported a sensitivity of 100%, a specificity of 99.9%, and a median turn-around time of 26.1 h.
Food insecurity (FI) affects 11.1% of U.S. households with higher rates for patients in the emergency department (ED) and those with cancer. A convenience sample of patients undergoing cancer ...treatment at an academic medical center's ED was used to understand FI prevalence using the HFIAS tool. A total of 105 patients enrolled in-person or telephone. FI prevalence was 14.3%. Participants preferred fresh produce, meal delivery service, or money for food compared to food bank services. About 75% felt the COVID-19 pandemic impacted their access to food. FI affects patients with cancer in the ED at higher rates than the US.
