White-nose syndrome (WNS) is a fungal wildlife disease of bats that has caused precipitous declines in certain Nearctic bat species. A key driver of mortality is premature exhaustion of fat reserves, primarily white adipose tissue (WAT), that bats rely on to meet their metabolic needs during winter. However, the pathophysiological and metabolic effects of WNS have remained ill-defined.
View Article and Find Full Text PDFWhite-nose syndrome is a fungal disease that has decimated hibernating bats from multiple North American species. In 2014, the invasive fungus arrived at a hibernaculum of little brown bats (Myotis lucifugus) inside the spillway of Tippy Dam, located near Wellston, Michigan, USA, yet surprisingly, this population has not experienced the declines seen elsewhere. Unlike a typical subterranean hibernaculum, light enters the spillway through small ventilation holes.

Objective: To identify a recommended minimum set of core outcomes for basal cell carcinoma clinical trials.
Background: The lack of uniformity in the outcomes reported in clinical studies of the treatment of cutaneous squamous cell carcinoma (cSCC) complicates efforts to compare treatment effectiveness across trials.
Objectives: To develop a core outcome set (COS), a minimum set of agreed-upon outcomes to be measured in all clinical trials of a given disease or outcome, for the treatment of cSCC.
Methods: One hundred and nine outcomes were identified via a systematic literature review and interviews with 28 stakeholders.
Novel pathogens can cause massive declines in populations, and even extirpation of hosts. But disease can also act as a selective pressure on survivors, driving the evolution of resistance or tolerance. Bat white-nose syndrome (WNS) is a rapidly spreading wildlife disease in North America.

Although the majority of transmissions often occurs within social groups, the contribution of connections that bridge groups and species to pathogen dynamics is poorly understood. These cryptic connections-which are often indirect or infrequent-provide transmission routes between otherwise disconnected individuals and may have a key role in large-scale outbreaks that span multiple populations or species.

Objective: To assess the difference in frequency of which reconstruction repairs are selected after MMS, among Mohs surgeons and facial plastic surgeons (FPS), and evaluate whether the level of satisfaction with the final repair outcome differed between specialties.
Materials And Methods: The study was approved by the Saint Louis University Institutional Review Board.
Host responses to infection with novel pathogens are costly and require trade-offs among physiologic systems. One such pathogen is the fungus Pseudogymnoascus destructans (Pd) that causes white-nose syndrome (WNS) and has led to mass mortality of hibernating bats in eastern North America. Although infection with Pd does not always result in death, we hypothesized that bats that survive infection suffer significant consequences that negatively impact the ability of females to reproduce.

Although risk of metastasis is low, basal cell carcinoma can be invasive and infiltrate important underlying structures such as bone or cartilage.

Genetic heritage, prior ultraviolet light exposure, and Fitzpatrick skin type may be associated with the rate and type of facial aging.

Clinical investigations into SCC treatment are common, but the outcomes reported are highly variable, omitted, or clinically irrelevant. The outcome heterogeneity and reporting bias of these studies leave clinicians unable to accurately compare studies.

To experimentally determine susceptibility differences between species, we exposed hibernating naïve little brown myotis (Myotis lucifugus) and big brown bats (Eptesicus fuscus) to the fungus that causes WNS, Pseudogymnoascus destructans (Pd). After hibernating under identical conditions, Pd lesions were significantly more prevalent and more severe in little brown myotis.

(), the psychrophilic fungus responsible for WNS, prospers in the winter habitat of many hibernating bat species. The immune response that elicits in bats is not yet fully understood; antibodies are produced in response to infection by , but they may not be protective and indeed may be harmful.

Candidatus Bartonella mayotimonensis was detected in 2010 from an aortic valve sample of a patient with endocarditis from Iowa, the United States of America. The environmental source of the potentially new endocarditis-causing Bartonella remained elusive. We set out to study the prevalence and diversity of bat-associated Bartonella in North America.

Most treatment options have only been studied in patients with axillary hyperhidrosis, and more studies are needed to develop therapies for other body regions. Several clinical trials are underway with promising preliminary results; however, there is still a large need for new therapies.

Numerous nonsurgical options for periorbital rejuvenation are available and can be used alone or as adjuncts to other nonsurgical and surgical options. Topicals, chemical peels, laser resurfacing, and dermabrasion therapy, along with neuromodulators and fillers, can be used to enhance the appearance of the periorbital region.

The behavioral and physiological changes associated with hibernation leave bats vulnerable to WNS, but the persistence of bats within the contaminated regions of North America suggests that survival might vary predictably among individuals or in relation to environmental conditions.
