Role of Inflammaging on the Reproductive Function and Pregnancy.

During female lifetime and pregnancy, inflammation and cellular senescence are implicated in physiological processes, from ovulation and menstruation, to placental homeostasis and delivery. Several lifestyles, nutritional, and environmental insults, as well as long-lasting pregestational inflammatory diseases may lead to detrimental effects in promoting and sustaining a chronic excessive inflammatory response and inflammaging, which finally contribute to the decay of fertility and pregnancy outcome, with a negative effect on placental function, fetal development, and future health risk profile in the offspring. Maladaptation to pregnancy and obstetric disease may in turn increase maternal inflammaging in a feedback loop, speeding up aging processes and outbreak of chronic diseases. Maternal inflammaging may also impact, through transgenerational effects, on future adult health. Hence, efficacious interventions should be implemented by physicians and healthcare professionals involved in prevention activities to reduce the modifiable factors contributing to the inflammaging process in order to improve public health.

A single-centre experience of intravenous thrombolysis for stroke in COVID-19 patients.

The sudden worldwide outbreak of Coronavirus Disease 2019 (COVID-19) has certainly provided new challenges in the management of acute ischaemic stroke, and the risk-benefit ratio of intravenous thrombolysis in COVID-19 positive patients is not well known. We describe four COVID-19 patients treated with intravenous thrombolysis for acute ischaemic stroke. Although rt-PA administration is the main therapeutic strategy, our patients experienced unpredictable complications and showed atypical features: the overall mortality was very high. In conclusion, in this article, we provide information about these cases and discuss the possible explanation behind this trend.

Size, shape and location of lacunar strokes and correlation with risk factors.

OBJECTIVE: We evaluated a prospective cohort of 150 patients under observation in our centre for lacunar strokes. The purpose of this study was to investigate if lacunar stroke of varying size, shape and locations had different risk factors between them and possibly different mechanisms and causes. PATIENTS AND METHODS: 150 patients with a lacunar stroke were included in the present study. Infarcts were classified by size, shape and location. We evaluated the correlation between several risk factors of stroke and the radiological characteristics of the infarcts. RESULTS: Older age was associated with the presence of a basal ganglia lesion (p < 0.001) and with the presence of a smaller lesion (trend to statistical significance, p = 0.07). Patients with infarcts >15 mm had higher NIHSS score at admission (p 0.01). CONCLUSION: The different subtypes of lacunar infarcts have distinct pathogenesis. Further studies, with a larger numbers of patients, are necessary to confirm our data.

Posterior reversible encephalopathy syndrome as the initial manifestation of Guillain-Barré syndrome: case report and review of the literature.

We report a 63-year-old female patient with Guillain-Barré syndrome revealed after posterior reversible encephalopathy syndrome. The onset was characterized by hypertension, headache, and cortical blindness, followed a few days later by progressive limb and facial paresis, dysautonomia, and respiratory failure. Treatment with plasmapheresis led to a rapid improvement of the clinical picture and the disappearance of magnetic resonance abnormalities. This report reviews the literature on this unusual association and discusses possible pathophysiological mechanisms.
