Landscape-scale drivers of spatial dynamics and genetic diversity in an emerging wildlife pathogen.

Aquatic pathogens often cannot tolerate drying, and thus their spread, and diversity across a landscape may depend on interactions between hydrological conditions and the movement of infected hosts. The aquatic fungus Batrachochytrium dendrobatidis (Bd) is a nearly ubiquitous pathogen of amphibians and particular lineages have been associated with host declines. By coupling amphibian surveys with molecular pathogen detection and genotyping techniques, we characterized the spatial dynamics and genetic diversity of Bd on a landscape containing both permanent and ephemeral ponds.

Diverse Relationships between Batrachochytrium Infections and Antimicrobial Peptide Defenses Across Leopard Frog Populations.

Antimicrobial peptides (AMPs) play a fundamental role in the innate defense against microbial pathogens, as well as other immune and non-immune functions. Their role in amphibian skin defense against the pathogenic fungus Batrachochytrium dendrobatidis (Bd) is exemplified by experiments in which depletion of host's stored AMPs increases mortality from infection. Yet, the question remains whether there are generalizable patterns of negative or positive correlations between stored AMP defenses and the probability of infection or infection intensity across populations and species.

and : fungal priority pathogens in laboratory diagnosis.

and are two fungal genera recently recognized in the list of fungal priority pathogens. They cause a wide range of diseases that affect humans, animals, and plants. In clinical laboratories, there is increasing concern about diagnosis due to limitations in sample collection and morphological identification.

Global patterns of allochthony in stream-riparian meta-ecosystems.

Ecosystems that are coupled by reciprocal flows of energy and nutrient subsidies can be viewed as a single "meta-ecosystem." Despite these connections, the reciprocal flow of subsidies is greatly asymmetrical and seasonally pulsed. Here, we synthesize existing literature on stream-riparian meta-ecosystems to quantify global patterns of the amount of subsidy consumption by organisms, known as "allochthony.

Effects of temperature on the interaction between amphibian skin bacteria and .

Symbiotic relationships between animals and microbes are important for a range of functions, from digestion to protection from pathogens. However, the impact of temperature variation on these animal-microbe interactions remains poorly understood. Amphibians have experienced population declines and even extinctions on a global scale due to chytridiomycosis, a disease caused by chytrid fungi in the genus .

Acoustically targeted noninvasive gene therapy in large brain volumes.

Focused Ultrasound Blood-Brain Barrier Opening (FUS-BBBO) can deliver adeno-associated viral vectors (AAVs) to treat genetic disorders of the brain. However, such disorders often affect large brain regions. Moreover, the applicability of FUS-BBBO in the treatment of brain-wide genetic disorders has not yet been evaluated.

Budget impact analysis of primary screening with the HPV test and genotyping against conventional cytology in Colombia.

Introduction: The detection of the human papillomavirus (HPV) through the combination of the HPV test and other techniques such as cytology has impacted the detection and timely treatment of lesions associated with cervical cancer. Objective: To estimate the budgetary impact of the strategy of early detection of HPV with DNA test genotyping with reflex cytology versus conventional cytology in women aged 30 to 65 years attending the cervical cancer screening program at a health benefit managing entity in Colombia. Materials and methods: Using a decision tree and a Markov model, the clinical implications and direct costs of screening, diagnosis, and treatment were estimated in a cohort of women.

Once a reservoir, always a reservoir? Seasonality affects the pathogen maintenance potential of amphibian hosts.

Host species that can independently maintain a pathogen in a host community and contribute to infection in other species are important targets for disease management. However, the potential of host species to maintain a pathogen is not fixed over time, and an important challenge is understanding how within- and across-season variability in host maintenance potential affects pathogen persistence over longer time scales relevant for disease management (e.g.

Pregnancy outcomes of women with multiple sclerosis treated with ocrelizumab in Canada: A descriptive analysis of real-world data.

Objectives: To report and describe the real-world use of ocrelizumab in women with multiple sclerosis (MS) in Canada before and/or during pregnancy as well as their fetal outcomes.

Methods: We identified retrospective and prospective Canadian pregnancy exposure cases from the Roche Global Safety Database from November 5, 2008 until March 31, 2021, and linked these cases to information within the Canadian Roche Patient Support Program (COMPASS). The analysis only included spontaneous reports or those from a non-interventional program.

Host species is linked to pathogen genotype for the amphibian chytrid fungus (Batrachochytrium dendrobatidis).

Host-pathogen specificity can arise from certain selective environments mediated by both the host and pathogen. Therefore, understanding the degree to which host species identity is correlated with pathogen genotype can help reveal historical host-pathogen dynamics. One animal disease of particular concern is chytridiomycosis, typically caused by the global panzootic lineage of the amphibian chytrid fungus (Batrachochytrium dendrobatidis, Bd), termed Bd-GPL.

His last breath.

Dying alone in a hospital bed is not what I envision when I think about my own death. As a third-year medical student, I have the honor of serving as leader for No One Dies Alone at my medical institution. I want to share my story to inspire others to participate in vigils with one who is dying or to assist in the efforts to contact family.

A multicentre real-world data study to assess the bleeding rate and management of patients with haemophilia A and factor VIII inhibitors in Argentina.

The development of inhibitors against factor VIII (FVIII) concentrates is a severe complication of treatment for patients with haemophilia. We investigated annualized bleeding rates (ABRs) in patients in Argentina with haemophilia A with inhibitors and analysed potential differences between treatment strategies. This multicentre, retrospective, real-world data, cohort design study comprised ambulatory paediatric and adult patients with congenital haemophilia A and FVIII inhibitors treated according to standard clinical practice, with 12-months follow-up.

A One Health Perspective to Recognize as Important in Clinical Practice.

Any strategy that proposes solutions to health-related problems recognizes that people, animals, and the environment are interconnected. is an example of this interaction because it is capable of infecting plants, animals, and humans. This review provides information on various aspects of these relations and proposes how to approach fusariosis with a One Health methodology (a multidisciplinary, and multisectoral approach that can address urgent, ongoing, or potential health threats to humans, animals, and the environment).

Baseline Functional Status and One-year Mortality After Hospital Admission in Elderly Patients: a prospective cohort study.

Introduction: Hospitalization represents a major factor that may precipitate the loss of functional status and the cascade into dependence. The main objective of our study was to determine the effect of functional status measured before hospital admission on survival at one year after hospitalization in elderly patients.

Methods: Prospective cohort study of adult patients (over 65 years of age) admitted to either the general ward or intensive Care units (ICU) of a tertiary teaching hospital in Buenos Aires, Argentina.

Evaluating environmental DNA as a tool for detecting an amphibian pathogen using an optimized extraction method.

Environmental DNA (eDNA) detection is a valuable conservation tool that can be used to identify and monitor imperiled or invasive species and wildlife pathogens. Batrachochytrium pathogens are of global conservation concern because they are a leading cause of amphibian decline. While eDNA techniques have been used to detect Batrachochytrium DNA in the environment, a systematic comparison of extraction methods across environmental samples is lacking.

Shifts in disease dynamics in a tropical amphibian assemblage are not due to pathogen attenuation.

Infectious diseases rarely end in extinction. Yet the mechanisms that explain how epidemics subside are difficult to pinpoint. We investigated host-pathogen interactions after the emergence of a lethal fungal pathogen in a tropical amphibian assemblage.

Prostanoids for critical limb ischaemia.

Background: Peripheral arterial occlusive disease (PAOD) is a common cause of morbidity and mortality due to cardiovascular disease in the general population. Although numerous treatments have been adopted for patients at different disease stages, no option other than amputation is available for patients presenting with critical limb ischaemia (CLI) unsuitable for rescue or reconstructive intervention. In this regard, prostanoids have been proposed as a therapeutic alternative, with the aim of increasing blood supply to the limb with occluded arteries through their vasodilatory, antithrombotic, and anti-inflammatory effects.

[Cross-cultural validation and telephonic reliability of modified "VIDA" questionnaire].

Instrumental activities scales allow the assessment of the functional status of the elderly; however, those currently used have gender bias and insufficient cross-cultural validation. The main objectives of this study were to perform the cross-cultural validation of the modified "VIDA: Daily living of the elderly questionnaire", created in Spain, into the Spanish spoken language in the City of Buenos Aires, and to evaluate its telephonic reliability. The secondary objective was to assess the concurrent validity of the modified VIDA questionnaire with the Lawton and Brody scale.
