Relevance of patient-centered actigraphy measures in pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension: a qualitative interview study.

Background: Pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) are severe, progressive diseases characterized by key symptoms such as dyspnea and fatigue. These symptoms impair physical functioning, with patients struggling to perform their daily activities. One traditional measure of physical functioning and exercise capacity is the 6-minute walk test (6MWT).

Divergent otolithic systems in the inner ear of Paranthropus robustus and Australopithecus africanus.

The bony labyrinth of the inner ear houses the sensory end-organs responsible for balance (otolithic system in the utricle and saccule, and semicircular canal system) and hearing (cochlea). Study of the bony labyrinth has revealed considerable morphological diversity in the hominin lineage (semicircular canals and cochleae) and aided in reconstructing essential aspects of primate evolution, including positional behavior, audition, and phylogenic affinities. However, evidence of evolutionary change in the hominin otolithic system remains elusive.

Bipedalism or bipedalisms: The os coxae of StW 573.

There has been a long debate about the possibility of multiple contemporaneous species of Australopithecus in both eastern and southern Africa, potentially exhibiting different forms of bipedal locomotion. Here, we describe the previously unreported morphology of the os coxae in the 3.67 Ma Australopithecus prometheus StW 573 from Sterkfontein Member 2, comparing it with variation in ossa coxae in living humans and apes as well as other Plio-Pleistocene hominins.

Association of risk assessment at diagnosis with healthcare resource utilization and health-related quality of life outcomes in pulmonary arterial hypertension.

We aimed to describe the clinical characteristics, healthcare resource utilization (HCRU) and costs, health-related quality of life (HRQoL), and survival for patients with pulmonary arterial hypertension (PAH), stratified by 1-year mortality risk at diagnosis. Adults diagnosed with PAH at the Sheffield Pulmonary Vascular Disease Unit between 2012 and 2019 were included. Patients were categorized as low, intermediate, or high risk for 1-year mortality at diagnosis.

Treatment and management of chronic thromboembolic pulmonary hypertension (CTEPH): A global cross-sectional scientific survey (CLARITY).

Advances in the treatment of chronic thromboembolic pulmonary hypertension (CTEPH) over the past decade changed the disease landscape, yet global insight on clinical practices remains limited. The CTEPH global cross-sectional scientific survey (CLARITY) aimed to gather information on the current diagnosis, treatment, and management of CTEPH and to identify unmet medical needs. This paper focuses on the treatment and management of CTEPH patients.

The Miocene primate Pliobates is a pliopithecoid.

The systematic status of the small-bodied catarrhine primate Pliobates cataloniae, from the Miocene (11.6 Ma) of Spain, is controversial because it displays a mosaic of primitive and derived features compared with extant hominoids (apes and humans). Cladistic analyses have recovered Pliobates as either a stem hominoid or as a pliopithecoid stem catarrhine (i.

Noninvasive single-cell-based prenatal genetic testing: A proof of concept clinical study.

Objective: To clinically assess a cell-based noninvasive prenatal genetic test using sequence-based copy number analysis of single trophoblasts from maternal blood.

Methods: Blood was obtained from 401 (243 + 158) individuals (8-22 weeks) and shipped overnight. Red cells were lysed, and nucleated cells stained for cytokeratin (CK) and CD45 and enriched for positive CK staining.

Recognition, diagnosis, and operability assessment of chronic thromboembolic pulmonary hypertension (CTEPH): A global cross-sectional scientific survey (CLARITY).

Early recognition and diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH) is crucial for improving prognosis and reducing the disease burden. Established clinical practice guidelines describe interventions for the diagnosis and evaluation of CTEPH, yet limited insight remains into clinical practice variation and barriers to care. The CTEPH global cross-sectional scientific survey (CLARITY) was developed to gather insights into the current diagnosis, treatment, and management of CTEPH and to identify unmet medical needs.

Risk assessment and real-world outcomes in chronic thromboembolic pulmonary hypertension: insights from a UK pulmonary hypertension referral service.

Objectives: This study was conducted to evaluate the ability of risk assessment to predict healthcare resource utilisation (HCRU), costs, treatments, health-related quality of life (HRQoL) and survival in patients diagnosed with chronic thromboembolic pulmonary hypertension (CTEPH).

Design: Retrospective observational study.

Setting: Pulmonary hypertension referral centre in the UK.

Use of the National Cancer Institute Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events to assess treatment tolerability in pulmonary arterial hypertension: qualitative patient research findings in current and former users of oral selexipag.

Background: Understanding patients' perspectives regarding drug tolerability, in addition to effectiveness, provides a complete picture of the patient experience and supports more informed therapeutic decision-making. The item library of the National Cancer Institute's Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) was developed to measure patient-reported frequency, severity, and interference of adverse events (AEs) associated with cancer therapies. This qualitative interview study assessed the suitability of items selected from the PRO-CTCAE library for assessing tolerability of selexipag, a medication targeting the prostacyclin pathway for patients with pulmonary arterial hypertension (PAH).

Patient Preferences in Pulmonary Arterial Hypertension, a Latent Class Analysis to Identify Preference Heterogeneity.

Objectives: Pulmonary arterial hypertension (PAH) is a chronic, progressive disease of the pulmonary circulation characterized by vascular remodeling that, if untreated, can lead to right heart dysfunction and death. This analysis measured heterogeneity in patient preferences for PAH-specific treatment regimens.

Method: Adult patients with PAH with slight to marked limitations during physical activity were recruited through a patient organization in Germany.

Broca's area, variation and taxic diversity in early from Koobi Fora (Kenya).

Because brain tissues rarely fossilize, pinpointing when and how modern human cerebral traits emerged in the hominin lineage is particularly challenging. The fragmentary nature of the fossil material, coupled with the difficulty of characterizing such a complex organ, has been the source of long-standing debates. Prominent among them are the uncertainties around the derived or primitive state of the brain organization in the earliest representatives of the genus , more particularly in key regions such as the Broca's area.

Societal costs associated to chronic thromboembolic pulmonary hypertension: A study utilizing linked national registries.

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare but serious complication after a pulmonary embolism. Healthcare resource utilization (HCRU; hospitalization, outpatient visits, and drug utilization) as well as productivity loss (sick leave and disability pension) before and after the CTEPH diagnosis is sparsely studied. By linking several Swedish national databases, this study estimated the societal costs in a national CTEPH cohort ( = 369, diagnosed with CTEPH in 2008-2019) 5 years before and 5 years after diagnosis (index date) and compared to an age, sex, and geographically matched control group ( = 1845, 1:5 match).

Comparative evaluation of costs and healthcare resource utilization of oral selexipag versus inhaled treprostinil or oral treprostinil in patients with pulmonary arterial hypertension.

Background: Pulmonary arterial hypertension (PAH), a rare vasculopathy progressively leading to right heart failure and death, is associated with considerable economic burden. Oral prostacyclin pathway agents (PPAs) like selexipag and treprostinil address an underlying PAH pathway, yet are often under-utilized. Data on head-to-head cost comparison of various PPAs is lacking.

Societal costs associated with pulmonary arterial hypertension: A study utilizing linked national registries.

Pulmonary arterial hypertension (PAH) is a progressive disease with no cure. Healthcare resource utilization (HCRU; hospitalization, outpatient visits, and drug utilization) before diagnosis and productivity loss (sick leave and disability pension) before and after PAH diagnosis are not well known. By linking several Swedish national databases, this study have estimated the societal costs in a national PAH cohort ( = 749, diagnosed with PAH in 2008-2019) 5 years before and 5 years after diagnosis and compared to an age, sex, and geographically matched control group ( = 3745, 1:5 match).

The Australopithecus assemblage from Sterkfontein Member 4 (South Africa) and the concept of variation in palaeontology.

Interpreting morphological variation within the early hominin fossil record is particularly challenging. Apart from the fact that there is no absolute threshold for defining species boundaries in palaeontology, the degree of variation related to sexual dimorphism, temporal depth, geographic variation or ontogeny is difficult to appreciate in a fossil taxon mainly represented by fragmentary specimens, and such variation could easily be conflated with taxonomic diversity. One of the most emblematic examples in paleoanthropology is the Australopithecus assemblage from the Sterkfontein Caves in South Africa.

Antisense oligonucleotide therapy rescues disturbed brain rhythms and sleep in juvenile and adult mouse models of Angelman syndrome.

encodes ubiquitin protein ligase E3A, and in neurons its expression from the paternal allele is repressed by the antisense transcript (). This leaves neurons susceptible to loss-of-function of maternal . Indeed, Angelman syndrome, a severe neurodevelopmental disorder, is caused by maternal deficiency.
