23 Impact of COVID-19 in gynecologic oncology: a nationwide Italian survey
Objective Several attempts are done in order to control COVID-19 and promote a fair allocation of resources during the outbreak. The Italian society of obstetrics and gynecologist (SIGO), and the Multicenter Italian Trials in Ovarian cancer and gynecologic malignancies (MITO) are promoting research activities in the field of gynecologic oncology on a national basis, even in the era of COVID-19. Methods The SIGO and MITO group promoted a national survey aiming to evaluate the impact of COVID-19 on clinical activity of gynecologist oncologists and the implementation of containment measures of COVID-19 diffusion. Results Overall, 604 participants completed the questionnaire with a response rat…

Impact of heteroptera pentatomidae feeding and oviposition on photosynthesis of herbaceous plants and egg parasitoids host location
The present study was designed to examine the effect of heteroptera pentatomidae feeding and/or oviposition on photosynthesis. Murgantia histrionica and Nezara viridula were fed on Brassica and Phaseolus plants, respectively. The changes in photosynthetic gas exchange and chlorophyll fluorescence parameters were followed immediately after the feeding as well as during the post-feeding period (24, 48 and 72 h). Murgantia feeding caused visible damage on leaf lamina, whereas this was not the case with Nezara feeding. In both cases a substantial decrease (50%) in photosynthesis was observed, which was partially restored only in Phaseolus plants by the end of the experiment. By using high resol…
A sex pheromone triggers courtship behaviour in the egg parasitoid Trissolcus brochymenae
Effect of dual biotic stress on plant volatile synomones used by egg parasitoids
Studies on semiochemical communication have demonstrated that broad bean plant, Vicia faba, emits volatile synomones induced by feeding and oviposition activities of the southern green stink bug, Nezara viridula, which recruit the egg parasitoid Trissolcus basalis. However plants growing in agro-ecosystems can be attacked by several herbivore species that could affect both above and belowground plant tissues with possible consequences for parasitoid recruitment. For example, broad bean plants can also be attacked by the leaf weevil, Sitona lineatus, and simultaneous attacks by the southern green stink bug and the leaf weevil can occur in agro- ecosystems. The purpose of this work was to inv…
Outcomes after perioperative SARS-CoV-2 infection in patients with proximal femoral fractures: an international cohort study
ObjectivesStudies have demonstrated high rates of mortality in people with proximal femoral fracture and SARS-CoV-2, but there is limited published data on the factors that influence mortality for clinicians to make informed treatment decisions. This study aims to report the 30-day mortality associated with perioperative infection of patients undergoing surgery for proximal femoral fractures and to examine the factors that influence mortality in a multivariate analysis.SettingProspective, international, multicentre, observational cohort study.ParticipantsPatients undergoing any operation for a proximal femoral fracture from 1 February to 30 April 2020 and with perioperative SARS-CoV-2 infec…
La localizzazione dell’ospite nei parassitoidi oofagi: il ruolo delle cere epicuticolari delle piante
La localizzazione dell’ospite nei parassitoidi oofagi è il risultato di un complesso comportamento di foraggiamento influenzato prevalentemente da stimoli di natura fisica e chimica. I segnali chimici (semiochimici) possono derivare dall’interazione tra la pianta e l’uovo ospite (sinomoni indotti dall’ovideposizione), dall’uovo tal quale (cairomoni diretti) e/o da stadi diversi da quello di uovo, come per esempio l’adulto (cairomoni indiretti). I sinomoni indotti con l’ovideposizione, capaci di richiamare i parassitoidi delle uova ancor prima che il fitofago possa causare danni, sono un efficace esempio del coinvolgimento “diretto” della pianta nel processo di localizzazione dell’ospite da …

Effect of COVID-19 pandemic lockdowns on planned cancer surgery for 15 tumour types in 61 countries: an international, prospective, cohort study
This international, prospective, cohort study enrolled 20 006 adult (≥18 years) patients from 466 hospitals in 61 countries with 15 cancer types, who had a decision for curative surgery during the COVID-19 pandemic and were followed up until the point of surgery or cessation of follow-up (Aug 31, 2020). Average national Oxford COVID-19 Stringency Index scores were calculated to define the government response to COVID-19 for each patient for the period they awaited surgery, and classified into light restrictions (index 60). The primary outcome was the non-operation rate (defined as the proportion of patients who did not undergo planned surgery). Cox proportional-hazards regression models wer…
