Surveillance imaging during first remission in follicular lymphoma does not impact overall survival.

Cancer 2021 Jun 22. Epub 2021 Jun 22.

Department of Hematology and Medical Oncology, Emory University-Winship Cancer Institute, Atlanta, Georgia.

Background: Although many patients with follicular lymphoma (FL) undergo routine radiographic surveillance during their first remission, no consensus exists on the modality, duration, frequency, or need for routine imaging studies. The authors retrospectively examined the effect of surveillance imaging on relapse detection and overall survival (OS) in patients with FL.

Methods: Patients with newly diagnosed FL who had a response to induction therapy were identified from the Lymphoid Malignancies Enterprise Architecture Database (LEAD) at Emory University and from the Molecular Epidemiology Resource (MER) of the University of Iowa/Mayo Clinic. Read More

Subgroups of failure after surgery for pelvic organ prolapse and associations with quality of life outcomes: a longitudinal cluster analysis.

Am J Obstet Gynecol 2021 Jun 19. Epub 2021 Jun 19.


Background: Treatment outcomes after pelvic organ prolapse (POP) surgery are often presented as dichotomous 'success or failure' based upon anatomic and symptom criteria. However, clinical experience suggests some women with outcome 'failures' are asymptomatic and perceive their surgery to be successful, while others have anatomic resolution, but continue to report symptoms. Characterizing failure types could be a useful step to refine definitions of success, understand mechanisms of failure, and identify individuals who may benefit from specific therapies. Read More

J Evol Biol 2021 Jun 22. Epub 2021 Jun 22.

ISEM, University of Montpellier, CNRS, EPHE, IRD, Montpellier, France.

Dispersal is a central determinant of spatial dynamics in communities and ecosystems, and various ecological factors can shape the evolution of constitutive and plastic dispersal behaviours. One important driver of dispersal plasticity is the biotic environment. Parasites, for example, influence the internal condition of infected hosts and define external patch quality. Read More

Proven COVID-19-associated pulmonary aspergillosis in patients with severe respiratory failure.

Mycoses 2021 Jun 22. Epub 2021 Jun 22.

Department of Cardiac, Thoracic, Vascular Sciences, and Public Health, Pathology Unit, University of Padova, Medical School, Padova, Italy.

Background: An increasing number of reports have described the COVID-19 associated pulmonary aspergillosis (CAPA) as being a further contributing factor to mortality. Based on a recent consensus statement supported by international medical mycology societies, it has been proposed to define CAPA as possible, probable, or proven on the basis of sample validity and thus diagnostic certainty. Considering current challenges associated with proven diagnoses there is pressing need to study the epidemiology of proven CAPA. Read More

Post-9/11 excess risk of thyroid cancer: Surveillance or exposure?

Am J Ind Med 2021 Jun 22. Epub 2021 Jun 22.

Institute for Translational Epidemiology, Icahn School of Medicine at Mount Sinai, New York, New York, USA.

An excess risk of thyroid cancer has been reported in different World Trade Center (WTC)-dust exposed cohorts. Increased surveillance of these cohorts has been suggested as a potential explanation of this reported excess thyroid cancer risk leading to an increased diagnosis of earlier-stage thyroid cancers. However, the uncertainty to what extent surveillance or physician bias may be contributing to the reported incidence of thyroid cancer in WTC-dust exposed populations remains, highlighting the need to investigate a potential causal link between WTC dust exposure and thyroid cancer.
