Interictal and postictal F-FDG PET/CT in epileptogenic zone localization.

Objective: To evaluate the performance of F-fluorodeoxyglucose positron-emission tomography/computed tomography ( F-FDG PET/CT) in localizing epileptogenic zones, comparing F-FDG injection performed in the traditional interictal period with that performed near the time of a seizure.

Materials And Methods: We evaluated patients with refractory epilepsy who underwent F-FDG PET/CT. The reference standards for localization of the epileptogenic zone were histopathology and follow-up examinations (in patients who underwent surgery) or serial electroencephalography (EEG) recordings, long-term video EEG, and magnetic resonance imaging (in patients who did not).

Impact of androgen deprivation therapy on mortality of prostate cancer patients with COVID-19: a propensity score-based analysis.

Background: Previous studies hypothesized that androgen deprivation therapy (ADT) may reduce severe acute respiratory syndrome coronavirus 2 (SARS-COV2) infectivity. However, it is unknown whether there is an association between ADT and a higher survival in prostate cancer patients with COVID-19.

Methods: We performed a retrospective analysis of prostate cancer (PC) patients hospitalized to treat COVID-19 in Brazil's public health system.

The golden hour for postpartum hemorrhage: Results from a prospective cohort study.

Objective: To evaluate the predictive capacity of vital signs for the diagnosis of postpartum hemorrhage (PPH).

Methods: A prospective cohort study performed at the University of Campinas, Brazil, between February 2015 and March 2016 with women who delivered vaginally. Vital signs and postpartum bleeding were collected over 24 h.

Anesthesia technique and postpartum hemorrhage: a prospective cohort study.

Background And Objective: During the past few years, an increased number of postpartum hemorrhages have been noticed, even in high-income countries. It has been suggested that this escalation could be associated with increased obstetric interventions. Among such interventions, anesthesia is one of the most prevalent.

Outcomes of COVID-19 Patients under Cytotoxic Cancer Chemotherapy in Brazil.

Background: Cancer patients present a distinct vulnerability to COVID-19. It is unclear if chemotherapy could accentuate the overall risk in these patients.

Methods: We performed a retrospective analysis linking COVID-19 data and oncological information systems to compare lethality in patients undergoing cytotoxic chemotherapy before COVID-19.

Use of cystatin C and serum creatinine for the diagnosis of contrast-induced nephropathy in patients undergoing contrast-enhanced computed tomography at an oncology centre.

Objective: Our aim was to assess renal function using as laboratory measurements serum creatinine and cystatin C concentrations before and after administration of low-osmolarity (nonionic) iodinated contrast medium in patients with cancer undergoing computed tomography (CT).

Methods: This prospective study included 400 oncologic outpatients. Serum creatinine and cystatin C concentrations were measured before and 72 h after contrast administration.
