Background And Purpose: Previous studies have postulated that poststroke depression (PSD) might be related to cumulative vascular brain pathology rather than to the location and severity of a single macroinfarct. We performed a detailed analysis of all types of microvascular lesions and lacunes in 41 prospectively documented and consecutively autopsied stroke cases.
Methods: Only cases with first-onset depression <2 years after stroke were considered as PSD in the present series. Diagnosis of depression was established prospectively using DSM-IV criteria for major depression. Neuropathological evaluation included bilateral semiquantitative assessment of microvascular ischemic pathology and lacunes; statistical analysis included Fisher exact test, Mann-Whitney U test, and regression models.
Results: Macroinfarct site was not related to the occurrence of PSD for any of the locations studied. Thalamic and basal ganglia lacunes occurred significantly more often in PSD cases. Higher lacune scores in basal ganglia, thalamus, and deep white matter were associated with an increased PSD risk. In contrast, microinfarct and diffuse or periventricular demyelination scores were not increased in PSD. The combined lacune score (thalamic plus basal ganglia plus deep white matter) explained 25% of the variability of PSD occurrence.
Conclusions: The cumulative vascular burden resulting from chronic accumulation of lacunar infarcts within the thalamus, basal ganglia, and deep white matter may be more important than single infarcts in the prediction of PSD.

Introduction: Cerebrovascular pathologic changes (CVPC) are prevalent and associated with dementia in those ≥ 90 years. However, CVPC associations to traditional risk factors (hypertension, diabetes, and hyperlipidemia) are variable. We hypothesized that neither traditional risk factors nor related medications would be associated with CVPC presence.

Background: Diabetes mellitus is closely related to periodontal disease and dental lesions, disorders which through dental infection and metabolic imbalance become negatively potentiated and cause a vicious circle that is almost impossible to break. The aim of this research was to study if the severity of dental and periodontal lesions is related to the presence of microvascular complications and glycemic control in patients with type 2 diabetes mellitus (T2DM).
Methods: In total, 112 subjects with T2DM that underwent a dental evaluation were enrolled in this case-control study.

To quantify microvascular lesions in a large real-world data (RWD) set, based on single central retinal fundus images of diabetic eyes from different origins, with the aim of validating its use as a precision tool for classifying diabetic retinopathy (DR) severity. Retrospective meta-analysis across multiple fundus image datasets. The study analyzed 2445 retinal fundus images from diabetic patients across four diverse RWD international datasets, including populations from Spain, India, China and the US.

Background/objectives: Superficial esophageal cancer is diagnosed by evaluating the vascular architecture, including dilation, tortuosity, caliber change, and shape, of a lesion. However, this diagnosis is subjective and requires extensive experience. Endoscopically distinguishing squamous intraepithelial neoplasia (SIN) from esophageal cancer is difficult.

Robust preclinical models of asymmetric ventricular loading in late gestation reflecting conditions such as hypoplastic left heart syndrome are lacking. We characterized the morphometry and microvascular function of the hypoplastic left ventricle (LV) and remaining right ventricle (RV) in a sham-controlled late gestation fetal lamb model of impaired left ventricular inflow (ILVI). Singleton fetuses were instrumented at ∼120 days gestational age (dGA; term is ∼147 days) with vascular catheters, an aortic flow probe and a deflated left atrial balloon.
