Tauopathies, including Alzheimer's disease and primary age-related tauopathy (PART), present heterogeneous clinico-pathological phenotypes that include dementia, aphasia, motor neuron diseases, and psychiatric symptoms. PART is neuropathologically characterized by the presence of neurofibrillary tangles in limbic regions without significant Aβ deposition, but its clinical features have not yet been fully established. Here, we present two patients with distinct psychosis and behavioral symptoms. At autopsy, these patients showed tau pathologies that could not be classified as typical PART, although PART-like neurofibrillary tangles were present in limbic regions. Clinically, both patients were admitted to mental hospitals due to severe delusions or other neuropsychiatric/behavioral symptoms. The first case presented with hallucination, delusion, and apathy at age 70, and died of pancreatic cancer at age 75. He had neuronal cytoplasmic inclusions with selective accumulation of 3Rtau in the striatum and thorn-shaped astrocytes in the amygdala. The second case, who presented with abnormal behaviors such as wandering, agitation and disinhibition, exhibited limbic neurodegeneration with massive 4R tau-positive oligodendroglial inclusions in the medial temporal white matter. His age at onset was 73, and the duration of disease was 15 years. These findings support the notion that distinct limbic tau pathology with concomitant degeneration of the related neural circuits might induce specific psychosis and behavioral symptoms. This underlines the importance of neuropathological evaluation for both clinical education and practice in the fields of neuropathology and neuropsychiatry. 相似文献

Aim
To assess the safety and efficacy of tirzepatide in people of East Asian descent based on age and body mass index (BMI).Materials and Methods
Data of participants enrolled in East Asian countries in the SURPASS-1, -3, -4, -5, J-mono and J-combo phase 3 clinical trials were included. Participants with type 2 diabetes with a baseline HbA1c of 7.0% up to 11.0% and a BMI of 23 kg/m2 or greater or 25 kg/m2 or greater were included. Participants treated with tirzepatide 5, 10 or 15 mg were evaluated to assess the safety and efficacy of tirzepatide in people of East Asian descent (94% from Japan) based on age (< 65 and ≥ 65 years) and BMI (< 25 and ≥ 25 kg/m2). Key safety and efficacy outcomes were assessed.Results
At baseline, 73% of East Asian participants had a BMI of 25 kg/m2 or greater and 74% were younger than 65 years. At week 52, tirzepatide induced a similar dose-dependent reduction in HbA1c, waist circumference and BMI across subgroups. Across all BMI and age subgroups, mean absolute HbA1c reductions across the three doses ranged from 2.3% to 3.0%, and mean waist circumference reductions ranged from 4.3 to 9.8 cm. Improvements in absolute insulin sensitivity, assessed by homeostatic model assessment for insulin resistance, were greater in those with a baseline BMI of ≥ 25 kg/m2. Improvements in lipid profiles were similar across subgroups. While the safety profile of tirzepatide was broadly similar across BMI and age subgroups, drug discontinuation because of adverse events was higher in participants with a baseline age of ≥ 65 years.Conclusions
This post hoc analysis showed that once-weekly tirzepatide had a similar safety and efficacy profile across BMI and age subgroups in East Asian participants. 相似文献254.

Chronic renal failure and diabetes mellitus could also be risk factors of pseudoaneurysm of the internal carotid artery (ICA) due to malignant otitis externa (MOE). Although pseudoaneurysm of the ICA is a rarely encountered disease, it should always be taken into consideration when treating patients of MOE. 相似文献
