Moving object detection in video streams plays a key role in many computer vision applications. In particular, separation between background and foreground items represents a main prerequisite to carry out more complex tasks, such as object classification, vehicle tracking, and person re-identification. Despite the progress made in recent years, a main challenge of moving object detection still regards the management of dynamic aspects, including bootstrapping and illumination changes.

PURPOSE As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19–free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2.

OBJECTIVE: Current trends show a rise of attention given to breast cancer patients' quality of life and the surgical reconstructive result. Along with this trend, surgical training quality and efficacy are gaining importanceand innovative training methods such as onlinevideos shared on social media portals, are becoming main updating tools. In hazardous times like COVID-19 pandemic nowadays, online communication becomes of vital importance and adaptation and innovation are fundamental to keep research and education alive.

The presence of cyanobacteria and their toxins in water used as drinking water or for recreational purposes may represent a risk for human health. This work describes the development of an advanced analytical method for simultaneous determination of 21 cyanotoxins (including Microcystins, Cyanopeptolins, Anabaenopeptins and Microginins) in drinking water based on Ultra Performance Liquid Chromatography coupled with a Q-TOF mass spectrometer.

Large multicenter studies and meta-analysis have documented the diagnostic accuracy and the prognostic implications of stress echocardiography, cardiac magnetic resonance and, mainly, nuclear stress tests. However, none of them provides a comprehensive anatomical and functional evaluation within the same study as stress CT perfusion.

There is a growing interest on the risk of health care pro- fessionals to be exposed to SARS-CoV-2 during their activ- ity. Recent studies have demonstrated that SARS-CoV-2 can be easily transmitted by symptomatic and asymptomatic carriers, contributing to viral diffusion and pandemic potential. Moreover, studies have reported that SARS-CoV-2 maintains its biologic stability in aerosol and on surfaces for hours to days

The United Nations 2030 Agenda for Sustainable Development promotes the "Leaving no one behind" principle and sets goals in areas of critical importance.

Similar to other countries, also the internal healthcare system of the Vatican City State has been impacted by the COVID-19 pandemic. However, the experience accumulated so far, the ongoing prevention measures, the organizational efforts to avoid discontinuation of healthcare assistance, and the efforts to precociously identify new cases have contributed to minimize the impact of the pandemic on the State and will be of utmost importance in the coming months, along with a widespread vaccination campaign.

Objectives: Asymptomatic carriers account for over a third of all Coronavirus Disease 19 (COVID-19) cases and are characterized by the absence of symptoms but the same infectivity as symptomatic infections. The high percentage of asymptomatic COVID-19 patients is significant in settings with specific vulnerabilities, such as homeless shelters, where the consequences of an outbreak may be dramatic.

Objective: Coronavirus disease 2019 (COVID-19) has caused rapid and drastic changes in cancer management. The Italian Society of Gynecology and Obstetrics (SIGO), and the Multicenter Italian Trials in Ovarian cancer and gynecologic malignancies (MITO) promoted a national survey aiming to evaluate the impact of COVID-19 on clinical activity of gynecologist oncologists and to assess the implementation of containment measures against COVID-19 diffusion. Methods: The survey consisted of a self-administered, anonymous, online questionnaire.
