Developing, Piloting and Evaluating a Patient Support Portal for Men With Prostate Cancer in Victoria: An Action Research Study.

Introduction: Men with prostate cancer (PCa) and their support providers face challenges in accessing high-quality, impartial information tailored to their specific needs to enhance their overall care and decision-making. We describe the development, piloting and evaluation of the co-designed web portal 'BroSupPORT'.

Methods: IT teams developed and integrated BroSupPORT into the Victorian Prostate Cancer Outcomes Registry (PCOR-Vic) electronic patient-reported outcome follow-up process.

The history of women and hemophilia: a narrative review of evolving beliefs and testing practices.

The history of hemophilia is well documented, yet reports focus heavily on the male perspective and severe forms of the disease. Although hemophilia was initially believed to only affect men with women seen as silent carriers, it is now universally acknowledged that women and girls can also be affected. In this narrative review, we tracked the progression of beliefs about women and hemophilia as documented in the literature from pre-1800s to the present time.

A national assessment of standards of care for inherited bleeding disorders in Canada.

Aim: The Canadian Integrated and Comprehensive Care Standards for Inherited Bleeding Disorders were adopted in June 2020. In early 2023, a self-assessment of each of the 26 Canadian inherited bleeding disorder treatment centre's (IBDTCs) capacity to meet the Standards was conducted. The goal was to validate the standards by assessing appropriateness and adherence.

Codesigning a patient support portal with health professionals and men with prostate cancer: An action research study.

Introduction: The supportive care needs of men with prostate cancer (PCa) have been well documented, but little is known about how an online portal may address these. This study sought to determine priority issues facing men with PCa, barriers and enablers to accessing care and whether health professionals (HPs) and men would support the inclusion of a patient-reported outcome (PRO) comparator tool.

Methods: We conducted four online focus groups with HPs recruited from healthcare services in Victoria, followed by seven online codesign workshops with men with PCa, recruited through the Victorian Prostate Cancer Outcomes Registry, Prostate Cancer Foundation Australia and the Cancer Council Victoria.

Exploring statistical weight estimates for mitochondrial DNA matches involving heteroplasmy.

Massively parallel sequencing (MPS) of mitochondrial (mt) DNA allows forensic laboratories to report heteroplasmy on a routine basis. Statistical approaches will be needed to determine the relative frequency of observing an mtDNA haplotype when including the presence of a heteroplasmic site. Here, we examined 1301 control region (CR) sequences, collected from individuals in four major population groups (European, African, Asian, and Latino), and covering 24 geographically distributed haplogroups, to assess the rates of point heteroplasmy (PHP) on an individual and nucleotide position (np) basis.

Invisible bleeds: Lived experiences and barriers to care for men with hemophilia.

Introduction: Guidelines of the World Federation of Hemophilia support the provision of equitable, optimal care for people with hemophilia (PWH). However, limited research exists examining the lived experiences of PWH or the barriers to care they may encounter. The primary objective of this exploratory study was to describe the experiences of men with hemophilia in Canada.

"Everything was blood when it comes to me": Understanding the lived experiences of women with inherited bleeding disorders.

Introduction: Despite the many symptoms that women with inherited bleeding disorders experience, no study has specifically sought to explore and understand the lived experiences of these women, nor the barriers to care that they may encounter. The primary objective of this study was to describe the lived experiences of women with inherited bleeding disorders.

Methods: Inclusion criteria for study enrollment were the following: age ≥18 years, English speaking, and confirmed diagnosis of an inherited bleeding disorder.

Healthcare provider perspectives on inequities in access to care for patients with inherited bleeding disorders.

Introduction: The ways in which social determinants of health affect patients with inherited bleeding disorders remains unclear. The objective of this study was to understand healthcare provider perspectives regarding access to care and diagnostic delay amongst this patient population.

Methods: A healthcare provider survey comprising 24 questions was developed, tested, and subsequently disseminated online with recruitment to all members of The Association of Hemophilia Clinic Directors of Canada (N = 73), members of the Canadian Association of Nurses in Hemophilia Care (N = 40) and members of the Canadian Physiotherapists in Hemophilia Care (N = 44).

Evaluating the Impact of Pneumonia Prevention Recommendations After Cardiac Surgery.

Background: Pneumonia is the most prevalent healthcare-associated infection after coronary artery bypass grafting (CABG), but the relative effectiveness of strategies to reduce its incidence remains unclear. We evaluated the relationship between healthcare-associated infection recommendations and risk of pneumonia after CABG.

Methods: Pneumonia prevention practice recommendations were developed based on literature review and analysis of semistructured interviews with key health care personnel across centers with low (<5.

Intrapelvic Femoral Head Dislocation without Associated Proximal Femur Fracture: A Case Report and Description of Closed Reduction Technique.

Traumatic hip dislocations are potentially devastating injuries, especially in young patients, and require emergent orthopedic treatment. Given the significant amount of energy required to cause these injuries, a high index of suspicion is necessary to identify related injuries. The associated injuries, direction of dislocation, and time between injury and reduction represent the known prognostic factors, based on limited available research.

Bacterial Septic Arthritis of the Adult Native Knee Joint: A Review.

» Acute bacterial septic arthritis of the knee is an orthopaedic emergency and, if left untreated, can result in substantial joint degradation. » Important risk factors for development of septic arthritis include age of >60 years, recent bacteremia, diabetes, cancer, cirrhosis, renal disease, drug or alcohol abuse, a history of corticosteroid injection, a recent injury or surgical procedure, a prosthetic joint, and a history of rheumatoid arthritis. » The diagnosis is primarily based on history and clinical presentation of a red, warm, swollen, and painful joint with limited range of motion.

Pronounced somatic bottleneck in mitochondrial DNA of human hair.

is the presence of variable mitochondrial DNA (mtDNA) within the same individual. The dynamics of heteroplasmy allele frequency among tissues of the human body is not well understood. Here, we measured allele frequency at heteroplasmic sites in two to eight hairs from each of 11 humans using next-generation sequencing.

Bottleneck and selection in the germline and maternal age influence transmission of mitochondrial DNA in human pedigrees.

Heteroplasmy-the presence of multiple mitochondrial DNA (mtDNA) haplotypes in an individual-can lead to numerous mitochondrial diseases. The presentation of such diseases depends on the frequency of the heteroplasmic variant in tissues, which, in turn, depends on the dynamics of mtDNA transmissions during germline and somatic development. Thus, understanding and predicting these dynamics between generations and within individuals is medically relevant.

Achieving the unimaginable: Health equity in haemophilia.

Historically, treatment based on the availability of clotting factor replacement has resulted in an arcane guideline for the correction of factor deficiencies in people with haemophilia (PwH). While all other disease entities seek to restore function to a normal level, PwH are restricted to factor nadirs still equivalent to mild or moderate disease, resulting in continued risk of bleeding. A new treatment paradigm is needed based on the defined needs of PwH.

An approximate full-likelihood method for inferring selection and allele frequency trajectories from DNA sequence data.

Most current methods for detecting natural selection from DNA sequence data are limited in that they are either based on summary statistics or a composite likelihood, and as a consequence, do not make full use of the information available in DNA sequence data. We here present a new importance sampling approach for approximating the full likelihood function for the selection coefficient. Our method CLUES treats the ancestral recombination graph (ARG) as a latent variable that is integrated out using previously published Markov Chain Monte Carlo (MCMC) methods.

External fixator-augmented flexible intramedullary nailing of an unstable pediatric femoral shaft fracture model: a biomechanical study.

The objective of this study was to test the compressive strength and torsional stiffness provided by the addition of a two-pin external fixator to an unstable pediatric femoral shaft fracture model after being instrumented with flexible intramedullary nailing (FIMN), and to compare this to bridge plating and FIMN alone. A length-unstable oblique diaphyseal fracture was created in 15 pediatric sized small femur models. Fracture stabilization was achieved by three constructs: standard retrograde FIMN with two 3.

The Effect of Acute Pulmonary Hypertension on Tricuspid Annular Height, Strain, and Curvature in Sheep.

The tricuspid annulus shows significant alterations in patients with functional tricuspid regurgitation-tricuspid valve dysfunction that is secondary to other diseases such as pulmonary hypertension. Early changes in annular shape and dynamics may provide an understanding of disease mechanisms and could predict disease progression. To gain a mechanistic insight into these early changes we perform a spatially-resolved analysis of the effect of acute pulmonary hypertension on the tricuspid annulus in sheep.

Pleistocene land bridges act as semipermeable agents of avian gene flow in Wallacea.

Cyclical periods of global cooling have been important drivers of biotic differentiation throughout the Quaternary. Ice age-induced sea level fluctuations can lead to changing patterns of land connections, both facilitating and disrupting gene flow. In this study, we test if species with differing life histories are differentially affected by Quaternary land connections.

Increasing frequency of combination medical therapy in the treatment of acromegaly with the GH receptor antagonist pegvisomant.

Pegvisomant monotherapy is effective and safe in treatment of acromegaly. However, some clinicians combine pegvisomant with somatostatin analogues (SSA) or dopamine agonist (DA). In this analysis of ACROSTUDY, a long-term non-interventional study, the use of combination regimens was evaluated.

A Population Phylogenetic View of Mitochondrial Heteroplasmy.

The mitochondrion has recently emerged as an active player in myriad cellular processes. Additionally, it was recently shown that >200 diseases are known to be linked to variants in mitochondrial DNA or in nuclear genes interacting with mitochondria. This has reinvigorated interest in its biology and population genetics.

Engineering Analysis of Tricuspid Annular Dynamics in the Beating Ovine Heart.

Functional tricuspid regurgitation is a significant source of morbidity and mortality in the US. Furthermore, treatment of functional tricuspid regurgitation is suboptimal with significant recurrence rates, which may, at least in part, be due to our limited knowledge of the relationship between valvular shape and function. Here we study the dynamics of the healthy in vivo ovine tricuspid annulus to improve our understanding of normal annular deformations throughout the cardiac cycle.

The effects of Pleistocene climate change on biotic differentiation in a montane songbird clade from Wallacea.

The role of Pleistocene Ice Age in tropical diversification is poorly understood, especially in archipelagos, in which glaciation-induced sea level fluctuations may lead to complicated changes in land distribution. To assess how Pleistocene land bridges may have facilitated gene flow in tropical archipelagos, we investigated patterns of diversification in the rarely-collected rusty-bellied fantail Rhipidura teysmanni (Passeriformes: Rhipiduridae) complex from Wallacea using a combination of bioacoustic traits and whole-genome sequencing methods (dd-RADSeq). We report a biogeographic leapfrog pattern in the vocalizations of these birds, and uncover deep genomic divergence among island populations despite the presence of intermittent land connections between some.

Identification of Highly Specific scFvs against Total Adiponectin for Diagnostic Purposes.

Adiponectin is one of the most abundant adipokines secreted from adipose tissue. It acts as an endogenous insulin sensitizer and plasma concentrations are inversely correlated with obesity and metabolic syndrome. A decrease in plasma adiponectin levels normally indicates increased hormonal activity of the visceral lipid tissue, which is associated with decreased insulin sensitivity.

Population structure and coalescence in pedigrees: Comparisons to the structured coalescent and a framework for inference.

Contrary to what is often assumed in population genetics, independently segregating loci do not have completely independent ancestries, since all loci are inherited through a single, shared population pedigree. Previous work has shown that the non-independence between gene genealogies of independently segregating loci created by the population pedigree is weak in panmictic populations, and predictions made from standard coalescent theory are accurate for populations that are at least moderately sized. Here, we investigate patterns of coalescence in pedigrees of structured populations.
