Risk factors for venous thromboembolism in patients undergoing neoadjuvant chemotherapy as treatment for ovarian cancer.

Objective: During the treatment of ovarian cancer, the risk of venous thromboembolism (VTE) post operatively is well established, however, patients may be at even greater risk during neoadjuvant chemotherapy (NACT). This study aimed to determine the incidence and timing of VTE amongst patients undergoing NACT, whether there was an association with survival, and examine risk factors associated with the development of VTE.

Study Design: This was a retrospective cohort study of patients diagnosed with ovarian, fallopian tube and primary peritoneal cancer receiving neoadjuvant chemotherapy betweenApril 2011 and April 2022 at a gynaecological cancer centre in England.

Biochar made from and applied as a bifunctional electrocatalyst in Zn-air batteries.

Biochar has been prepared by pyrolysis of (the vegetable sponge produced by ) and activated by mixing the pyrolyzed powder with KOH and pyrolyzed again. Non-activated and activated biochar have both been structurally and then electrochemically characterized to record their differences and assess their suitability as bifunctional oxygen reduction and oxygen evolution reaction electrocatalysts in Zn-air batteries. Non activated biochar carries several functional groups; however, the activation procedure led to a material with mainly O and Mg groups.

Missed opportunities for early HIV diagnosis in Greece: The MORFEAS study, 2019 to 2021.

BackgroundLate HIV diagnosis (CD4+ T-cell count < 350 cells/μL, or with an AIDS-defining event) remains a persistent challenge in Greece, indicating potential missed opportunities (MOs) for earlier testing.AimTo determine the frequency of HIV indicator conditions (ICs) preceding diagnosis and to quantify MOs for earlier testing at a nationwide level in Greece.MethodsThis multicentre retrospective study analysed data on 823 antiretroviral therapy-naive adults (≥ 18 years) diagnosed with HIV during 2019-21.

Age and mating status have complex but modest effects on the critical thermal limits of adult Mediterranean fruit flies from geographically divergent populations.

The highly invasive Mediterranean fruit fly (medfly), Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), is currently expanding its geographic distribution into cooler temperate areas of the Northern Hemisphere. In marginal conditions, the invasion potential of medfly depends in part on innate tolerance to the novel environmental conditions. Physiological tolerances are potentially influenced by interactions among multiple factors, such as organism age or reproductive maturity, sex, and mating status.
