Distinguishing ASH clinical practice guidelines from other forms of ASH clinical advice.

The American Society of Hematology (ASH) develops a variety of resources that provide guidance to clinicians on the diagnosis and management of blood diseases. These resources include clinical practice guidelines (CPGs) and other forms of clinical advice. Although both ASH CPGs and other forms of clinical advice provide recommendations, they differ with respect to the methods underpinning their development, the principal type of recommendations they offer, their transparency and concordance with published evidence, and the time and resources required for their development.

Understanding Formal Caregiver Burden in Nursing Assistants in Nursing Homes: A Mixed Methods Approach.

The current study aimed to describe formal caregiver burden of nursing assistants in nursing homes. A descriptive, cross-sectional, convergent mixed methods approach identified attributes of formal caregiver burden using phenomenological interviews and established self-report measures. Themes included nursing assistants' experiences of stress, close relationships, extensive assistance of residents, balancing needs and routines, and feeling accomplished.

Characterization of Classical Sheep Scrapie in White-tailed Deer after Experimental Oronasal Exposure.

Background: Classic scrapie is a prion disease of sheep and goats that is associated with accumulation of abnormal prion protein (PrPSc) in the central nervous and lymphoid tissues. Chronic wasting disease (CWD) is the prion disease of cervids. This study was conducted to determine the susceptibility of white-tailed deer (WTD) to the classic scrapie agent.

How to write a guideline: a proposal for a manuscript template that supports the creation of trustworthy guidelines.

Trustworthy health guidelines should provide recommendations, document the development process, and highlight implementation information. Our objective was to develop a guideline manuscript template to help authors write a complete and useful report. The McMaster Grading of Recommendations Assessment, Development and Evaluation Centre collaborated with the American Society of Hematology (ASH) to develop guidelines for the management of venous thromboembolism.

Methodology for adaptation of the ASH Guidelines for Management of Venous Thromboembolism for the Latin American context.

Background: From 2017 to 2020, the American Society of Hematology (ASH) collaborated with 12 hematology societies in Latin America to adapt the ASH guidelines on venous thromboembolism (VTE).

Objective: To describe the methods used to adapt the ASH guidelines on venous thromboembolism.

Methods: Each society nominated 1 individual to serve on the guideline panel.

Formal Caregiver Burden in Nursing Homes: An Integrative Review.

Formal caregivers in nursing homes provide care to vulnerable older adults with chronic conditions. Caregiver burden affects formal caregivers. The purpose of this integrative review was to explore formal caregiver burden among nursing staff in nursing homes.

Formal Caregiver Burden in Nursing Homes: A Concept Analysis.

Caregiver burden is a phrase often used interchangeably with the concepts of stress, strain, and burnout. Distinct differences may be relevant in formal caregiver burden; however, previous concept analyses have not addressed formal caregiver burden in nursing homes, which would be useful as a foundation for theory development and empirical testing. In the current study, based on Walker and Avant's concept analysis guidelines, articles were reviewed to identify the attributes, antecedents, and consequences of formal caregiver burden.

Methodology for the American Society of Hematology VTE guidelines: current best practice, innovations, and experiences.

Background: Methods for the development of clinical guidelines have advanced dramatically over the past 2 decades to strive for trustworthiness, transparency, user-friendliness, and rigor. The American Society of Hematology (ASH) guidelines on venous thromboembolism (VTE) have followed these advances, together with application of methodological innovations.

Objective: In this article, we describe methods and methodological innovations as a model to inform future guideline enterprises by ASH and others to achieve guideline standards.

A user guide to the American Society of Hematology clinical practice guidelines.

Since November 2018, Blood Advances has published American Society of Hematology (ASH) clinical practice guidelines on venous thromboembolism, immune thrombocytopenia, and sickle cell disease. More ASH guidelines on these and other topics are forthcoming. These guidelines have been developed using consistent processes, methods, terminology, and presentation formats.

Training curriculum to help patient representatives participate meaningfully in the development of clinical practice guidelines.

Patient participation in the development of clinical practice guidelines (CPGs) is critical for validity and trust. Many guideline panels now include patient representatives. Engagement of these individuals may be improved by training them about the process and their role before they join a guideline panel.

Experimental Transmission of the Chronic Wasting Disease Agent to Swine after Oral or Intracranial Inoculation.

Chronic wasting disease (CWD) is a naturally occurring, fatal neurodegenerative disease of cervids. The potential for swine to serve as hosts for the agent of CWD is unknown. The purpose of this study was to investigate the susceptibility of swine to the CWD agent following experimental oral or intracranial inoculation.

Scrapie in Swine: a Diagnostic Challenge.

A naturally occurring prion disease has not been recognized in swine, but the agent of bovine spongiform encephalopathy does transmit to swine by experimental routes. Swine are thought to have a robust species barrier when exposed to the naturally occurring prion diseases of other species, but the susceptibility of swine to the agent of sheep scrapie has not been thoroughly tested. We conducted this experiment to test the susceptibility of swine to U.

Horizontal Transmission of Chronic Wasting Disease in Reindeer.

We challenged reindeer by the intracranial route with the agent of chronic wasting disease sourced from white-tailed deer, mule deer, or elk and tested for horizontal transmission to naive reindeer. Reindeer were susceptible to chronic wasting disease regardless of source species. Horizontal transmission occurred through direct contact or indirectly through the environment.

Lack of prion accumulation in lymphoid tissues of PRNP ARQ/ARR sheep intracranially inoculated with the agent of scrapie.

Sheep scrapie is a transmissible spongiform encephalopathy that can be transmitted horizontally. The prion protein gene (PRNP) profoundly influences the susceptibility of sheep to the scrapie agent and the tissue levels and distribution of PrPSc in affected sheep. The purpose of this study was to compare the survival time and PrPSc tissue distribution in sheep with highly resistant and highly susceptible PRNP genotypes after intracranial inoculation of the agent of scrapie.

Who's your expert? Use of an expert opinion survey to inform development of American Psychiatric Association practice guidelines.

Objective: For many clinical questions in psychiatry, high-quality evidence is lacking. Credible practice guidelines for such questions depend on transparent, reproducible, and valid methods for assessing expert opinion. The objective of this study was to develop and demonstrate the feasibility of a method for assessing expert opinion to aid in the development of practice guidelines by the American Psychiatric Association (APA).

Chronic wasting disease in bank voles: characterisation of the shortest incubation time model for prion diseases.

In order to assess the susceptibility of bank voles to chronic wasting disease (CWD), we inoculated voles carrying isoleucine or methionine at codon 109 (Bv109I and Bv109M, respectively) with CWD isolates from elk, mule deer and white-tailed deer. Efficient transmission rate (100%) was observed with mean survival times ranging from 156 to 281 days post inoculation. Subsequent passages in Bv109I allowed us to isolate from all CWD sources the same vole-adapted CWD strain (Bv(109I)CWD), typified by unprecedented short incubation times of 25-28 days and survival times of ∼35 days.

Susceptibility of cattle to the agent of chronic wasting disease from elk after intracranial inoculation.

Cattle could be exposed to the agent of chronic wasting disease (CWD) through contact with infected farmed or free-ranging cervids or exposure to contaminated premises. The purpose of the current study was to assess the potential for CWD derived from elk to transmit to cattle after intracranial inoculation. Calves (n = 14) were inoculated with brain homogenate derived from elk with CWD to determine the potential for transmission and to define the clinicopathologic features of disease.

Prolonged incubation time in sheep with prion protein containing lysine at position 171.

Sheep scrapie susceptibility or resistance is a function of genotype, with polymorphisms at codon 171 in the sheep prion gene playing a major role. Glutamine (Q) at codon 171 contributes to scrapie susceptibility, while arginine (R) is associated with resistance. In some breeds, lysine (K) occurs at codon 171, but its effect on scrapie resistance has not been determined.

Correlating levels of type III secretion and secreted proteins with fecal shedding of Escherichia coli O157:H7 in cattle.

The locus of enterocyte effacement (LEE) of Escherichia coli O157:H7 (O157) encodes a type III secretion system (T3SS) for secreting LEE-encoded and non-LEE-encoded virulence proteins that promote the adherence of O157 to intestinal epithelial cells and the persistence of this food-borne human pathogen in bovine intestines. In this study, we compared hha sepB and hha mutants of O157 for LEE transcription, T3SS activity, adherence to HEp-2 cells, persistence in bovine intestines, and the ability to induce changes in the expression of proinflammatory cytokines. LEE transcription was upregulated in the hha sepB and hha mutant strains compared to that in the wild-type strain, but the secretion of virulence proteins in the hha sepB mutant was severely compromised.

White-tailed deer are susceptible to the agent of sheep scrapie by intracerebral inoculation.

Interspecies transmission studies afford the opportunity to better understand the potential host range and origins of prion diseases. The purpose of this experiment was to determine susceptibility of white-tailed deer to the agent of scrapie after intracerebral inoculation and to compare clinical signs and lesions to those reported for chronic wasting disease (CWD). Deer (n = 5) were inoculated with 1 mL of a 10% (wt/vol) brain homogenate derived from a sheep clinically affected with scrapie.
