We evaluated age at natural menopause and the prevalence of premature ovarian failure (POF) in a monocentric Caucasian cohort of patients with systemic lupus erythematosus (SLE).
At the beginning of 2020, coronavirus disease 2019 (COVID-19) spreads worldwide. Patients with ovarian cancer should be considered at high-risk of developing severe morbidity related to COVID-19. Most of them are diagnosed in advanced stages of disease, and they are fragile. Here, we evaluated the major impact of COVID-19 on patients with ovarian cancer, discussing the effect of the outbreak on medical and surgical treatment.
Dental academic institutions are affected by COVID-19. We assessed the perceived COVID19 preparedness of these institutions and the characteristics of institutions with greater perceived preparedness. An international cross-sectional survey of dental academics was conducted from March to August 2020 to assess academics’ and institutional attributes, perceived preparedness, and availability of infection prevention and control (IPC) equipment. Principal component analysis (PCA) identified perceived preparedness components.
Increasing numbers of laboratories develop new methods based on gas-liquid and high-performance liquid chromatography to determine serum concentrations of oxygenated cholesterol metabolites such as 7α-, 24(S)-, and 27-hydroxycholesterol. We initiated a first international descriptive oxycholesterol (OCS) survey in 2013 and a second interventional survey 2014 in order to compare levels of OCS reported by different laboratories and to define possible sources of analytical errors.
Cholesterol and its oxygenated metabolites, such as oxysterols, are intensively investigated as potential players in the pathophysiology of brain disorder. Altered oxysterol levels have been described in patients with numerous neuropsychiatric disorders, including Alzheimer's disease, Amyotrophic Lateral Sclerosis, Parkinson's disease, X-linked adrenoleukodystrophy, and Smith-Lemli-Opitz Syndrome. Recent studies have shown that Autism Spectrum Disorders are associated with disruption of cholesterol metabolism.
It is now widely accepted that oxysterols are more than metabolic intermediates but are actually bona fide lipid mediators. To qualify as a bona fide lipid mediator, a lipid compound should meet three conditions. First to be endogenous, second to have its levels altered depending on the physiological or pathological situation, and third to induce a signaling response when its levels are altered. As is evident from the papers published in this Special issue, oxysterols largely qualify as bona fide lipid mediators.
The authors' aim is to define a framework around the history of studies and analyses on cranial trepanation. In addition, based on the analytical approach of Abele de Blasio, the authors would like to reach an understanding of the various different interpretations of the origin and aetiology of the art of cranial trepanation, starting in the prehistoric era. In this brief study, historical discussions are intertwined with ethnoiatric and anthropometric techniques of the author, leading the reader into a fascinating discussion on the practice of trepanation in ancient populations.
In Europe in 1918, influenza spread through Spain, France, Great Britain and Italy, causing havoc with military operations during the First World War. The influenza pandemic of 1918 killed more than 50 million people worldwide. In addition, its socioeconomic consequences were huge. "Spanish flu", as the infection was dubbed, hit different agegroups, displaying a so-called "W-trend", typically with two spikes in children and the elderly. However, healthy young adults were also affected.
Bicuspid aortic valve (BAV) disease is the most common congenital cardiac malformation associated with an increased lifetime risk and a high rate of surgically-relevant valve deterioration and aortic dilatation. Genomic data revealed that different genes are associated with BAV. A dominant genetic factor for the recent past was the basis to the recommendation for a more extensive aortic intervention.
Research on bicuspid aortic valve disease (BAV) and related com- plications has grown in an exponential manner in the last decades. However, the current knowledge of the mechanisms underlying the development of this disease is still limited, since all clinical and surgical studies on BAV mainly focused their objects on its major vascular complications, such as ascending aortic aneurysms and dissection.
