Besides the modulation of neuronal firing patterns, brain histamine levels are also thought to modulate functions of glial cells. Microglia are the innate immune cells and professional phagocytes of the central nervous system, and histamine was previously shown to have multiple effects on microglial functions in health and disease. Isolated microglia respond only to agonists of the Hrh2 subtype of histamine receptors (Hrh), and the expression of that isoform is confirmed by a metadata analysis of microglia transcriptomes. When we studied the effect of the histamine receptor isoforms in cortical and thalamic microglia by in situ live cell Ca2+ imaging using a novel, microglia-specific indicator mouse line, microglial cells respond to external histamine application mainly in a Hrh1-, and to a lower extent also in a Hrh2-dependent manner. The Hrh1 response was sensitive to blockers of purinergic P2ry12 receptors, and since Hrh1 expression was predominantly found in astrocytes, we suggest that the Hrh1 response in microglia is mediated by astrocyte ATP release and activation of P2ry12 receptors in microglia. Histamine also stimulates microglial phagocytic activity via Hrh1- and P2ry12-mediated signaling. Taken together, we provide evidence that histamine acts indirectly on microglial Ca2+ levels and phagocytic activity via astrocyte histamine receptor-controlled purinergic signaling.The inclusion of human body dissection in anatomical science curricula has been described as a critical educational experience for the mastery of anatomical structures and concepts. To ensure that body donors are ethically acquired and suitable for anatomy education, Anatomical Donation Programs (ADPs) are tasked with the responsibility of acquiring body donors for basic and clinical science curricula. Considering the personal and institutional impact of SARS-CoV-2, a national survey was conducted to examine the current effect of the pandemic on ADP protocols, body donation, and the sustainability of ADPs in the United States (U.S.). Eighty-nine U.S. ADPs were identified and contacted for optional participation in a survey to assess the impact of the SARS-CoV-2 pandemic on their programs. Survey data were collected and managed using REDCap electronic data capture tools. Thirty-six ADPs (40.5% response rate) from the nine U.S. Divisions are represented in the survey results. Data were collected on ADP descriptions and demographics, SARS-CoV-2 impact on ADPs and protocols, and body donation and ADP sustainability. Almost all ADPs reported that the pandemic has affected their ADP operations in some way; however, the sustainability for the majority of ADPs appears likely and donor availability remains stable due to a proportional decrease in body donations and body donor requests. As the long-term impact on ADPs has yet to be determined, the authors plan to reevaluate the lasting impact of the SARS-CoV-2 pandemic on body donation, ADP sustainability, and anatomical science education throughout the year 2021.Smoking is one of the most unhealthy behaviours and responsible for a variety of respiratory diseases. Although spirometric lung age (SLA) is regarded as an effective way to augment the smoking quit rate in other countries, it has not been calculated in Chinese smokers. Thus, the aim of this study was to determine the association of SLA with smoking status, and further explore whether smoking duration, dependence and other factors such as obesity and physical exercise affect SLA in Chinese current smokers. A total of 431 healthy men aged 20 years and older took part in the study from September 2018 to August 2019. Spirometric test was measured through a portable spirometry, and smoking status including smoking duration and dependence was investigated by using a questionnaire. SLA was calculated from an established equation which is based on the inverse calculation of the forced expiratory volume in one second in the Chinese population. Lung age difference (∆LA) could be obtained by counting the difference between SLA and chronological age. Results indicated that ∆LA is remarkably higher in current smokers than that in ex-smokers and non-smokers (p less then 0.01). The study also revealed that smoking duration and dependence are related to ∆LA. Smokers with long smoking duration (smoked ≥10 years) and high dependence (consumed ≥20 cigarettes per day) had a significantly higher ∆LA than their counterparties (p less then 0.01). Multiple regression analysis showed that body mass index, smoking duration and cigarettes per day were independently correlated with ∆LA in the current smokers (p less then 0.01). The findings suggest that not only smoking or not, but smoking duration, dependence and obesity are strongly associated with SLA.
Iron has been implicated in the pathogenesis of brain injury and hydrocephalus after preterm germinal matrix hemorrhage-intraventricular hemorrhage, however, it is unknown how external or endogenous intraventricular clearance of iron pathway proteins affect the outcome in this group.

This prospective multicenter cohort included patients with posthemorrhagic hydrocephalus (PHH) who underwent (1) temporary and permanent cerebrospinal fluid (CSF) diversion and (2) Bayley Scales of Infant Development-III testing around 2 years of age. CSF proteins in the iron handling pathway were analyzed longitudinally and compared to ventricle size and neurodevelopmental outcomes.

Thirty-seven patients met inclusion criteria with a median estimated gestational age at birth of 25 weeks; 65% were boys. Ventricular CSF levels of hemoglobin, iron, total bilirubin, and ferritin decreased between temporary and permanent CSF diversion with no change in CSF levels of ceruloplasmin, transferrin, haptoglobin, and hepcidin. There was an increase in CSF hemopexin during this interval.
