Strontium isoscape of sub-Saharan Africa allows tracing origins of victims of the transatlantic slave trade.

Strontium isotope (Sr/Sr) analysis with reference to strontium isotope landscapes (Sr isoscapes) allows reconstructing mobility and migration in archaeology, ecology, and forensics. However, despite the vast potential of research involving Sr/Sr analysis particularly in Africa, Sr isoscapes remain unavailable for the largest parts of the continent. Here, we measure the Sr/Sr ratios in 778 environmental samples from 24 African countries and combine this data with published data to model a bioavailable Sr isoscape for sub-Saharan Africa using random forest regression.

Germline de novo alterations of RUNX1T1 in individuals with neurodevelopmental and congenital anomalies.

Runt-related transcription factor 1 translocated to 1 (RUNX1T1; also known as eight-twenty-one [ETO]) encodes a transcription regulator for hematopoietic genes and is well known for its involvement in hematologic malignancies, particularly acute myeloid leukemia (AML). However, its role in congenital disease is less understood. This study provides detailed clinical and molecular information on three cases exhibiting neurodevelopmental and congenital anomalies with germline de novo alterations in RUNX1T1.

Strengthening the Chain: A Continuing Medical Education Program for Test Results Follow-up.

Introduction: The Canadian Medical Protective Association (CMPA)'s Commitment to Change in Test-Results Follow-Up (CTC-TRFU) program aims to provide physicians with resources to enhance their test results follow-up systems for improved patient safety. Framed around the Transtheoretical Model, the program involves a 6-month multimodal educational intervention involving individual and group coaching sessions, action planning, and reflection surveys.

Methods: This study evaluates the CTC-TRFU program's impact by analyzing survey responses and course documents, focusing on three main outcomes: physicians' perceived barriers and challenges, changes in their confidence and commitment, and implemented practice changes with perceived impact on patient safety.

Association between the A316T Mutation and Adolescent Idiopathic Scoliosis in French Canadian and Italian Cohorts.

Studies have revealed anthropometric discrepancies in girls with adolescent idiopathic scoliosis (AIS) compared to non-scoliotic subjects, such as a higher stature, lower weight, and lower body mass index. While the causes are still unknown, it was proposed that metabolic hormones could play a role in AIS pathophysiology. Our objectives were to evaluate the association of A316T polymorphism in AIS susceptibility and to study its relationship with disease severity and progression.

Biallelic variants in GTF3C5, a regulator of RNA polymerase III-mediated transcription, cause a multisystem developmental disorder.

General transcription factor IIIC subunit 5 (GTF3C5) encodes transcription factor IIIC63 (TFIIIC63). It binds to DNA to recruit another transcription factor, TFIIIB, and RNA polymerase III (Pol III) to mediate the transcription of small noncoding RNAs, such as tRNAs. Here, we report four individuals from three families presenting with a multisystem developmental disorder phenotype with biallelic variants in GTF3C5.

Visuo-Haptic Rendering of the Hand during 3D Manipulation in Augmented Reality.

Manipulating virtual objects with bare hands is a key interaction in Augmented Reality (AR) applications. However, there are still several limitations that affect the manipulation, including the lack of mutual visual occlusion between virtual and real content as well as the lack of haptic sensations. To address the two abovementioned matters, the role of the visuo-haptic rendering of the hand as sensory feedback is investigated.

Circulatory Adipokines and Incretins in Adolescent Idiopathic Scoliosis: A Pilot Study.

Adolescent idiopathic scoliosis (AIS) is a three-dimensional malformation of the spine of unknown cause that develops between 10 and 18 years old and affects 2-3% of adolescents, mostly girls. It has been reported that girls with AIS have a taller stature, lower body mass index (BMI), and bone mineral density (BMD) than their peers, but the causes remain unexplained. Energy metabolism discrepancies, including alterations in adipokine and incretin circulatory levels, could influence these parameters and contribute to disease pathophysiology.

Animal reactivity to camera traps and its effects on abundance estimate using distance sampling in the Taï National Park, Côte d'Ivoire.

The use of camera traps (CTs) has become an increasingly popular method of studying wildlife, as CTs are able to detect rare, nocturnal, and elusive species in remote and difficult-to-access areas. It thus makes them suited to estimate animal density and abundance, identify activity patterns and new behaviours of animals. However, animals can react when they see the CTs and this can lead to bias in the animal population estimates.

SLEAP: A deep learning system for multi-animal pose tracking.

The desire to understand how the brain generates and patterns behavior has driven rapid methodological innovation in tools to quantify natural animal behavior. While advances in deep learning and computer vision have enabled markerless pose estimation in individual animals, extending these to multiple animals presents unique challenges for studies of social behaviors or animals in their natural environments. Here we present Social LEAP Estimates Animal Poses (SLEAP), a machine learning system for multi-animal pose tracking.

Review about Psychological Barriers to Lifestyle Modification, Changes in Diet Habits, and Health-Related Quality of Life in Bariatric Endoscopy.

Obesity is an expanding disease responsible for significant deterioration in the Health-Related Quality of Life (HRQL) of those who suffer from it. Bariatric Endoscopy (BE) therapies have proven to be an effective treatment for this pathology. A multidisciplinary approach is essential for the successful therapeutic management of BE.

Delineating the genotypic and phenotypic spectrum of -related neurodevelopmental disorders.

Background: Variants in have recently been reported to cause a neurodevelopmental disorder with hypotonia, seizures and impaired language; however, only six variants have been reported and the clinical characteristics have only broadly been defined.

Methods: Molecular and clinical data were collected from clinical and research cohorts. Massive parallel sequencing was performed and identified individuals with a related neurodevelopmental disorder.

Lessons learned while protecting wild chimpanzees in West Africa.

Though human activities are postulated to be the main drivers of the worldwide biodiversity crisis, humans are also suggested by some to be an important part of the solution to the crisis. How can such a paradox be best solved? This paradox requires an adaptive, context-specific, dynamic solution, at a fine-grained scale that varies by location. The Wild Chimpanzee Foundation (WCF) works on the ground in three West African countries: In Côte d'Ivoire, where bushmeat consumption is a recurrent and generalized threat to wildlife, WCF used live theater performances in the villages to address this issue.

Environmental variability supports chimpanzee behavioural diversity.

Large brains and behavioural innovation are positively correlated, species-specific traits, associated with the behavioural flexibility animals need for adapting to seasonal and unpredictable habitats. Similar ecological challenges would have been important drivers throughout human evolution. However, studies examining the influence of environmental variability on within-species behavioural diversity are lacking despite the critical assumption that population diversification precedes genetic divergence and speciation.

Re-suturing after primary endoscopic sleeve gastroplasty (ESG) for obesity.

Introduction: Although primary endoscopic sleeve gastroplasty (P-ESG) is effective, some patients may require revision procedures to augment weight loss. We hypothesized that a non-surgical approach using redo ESG (R-ESG) might be a viable option in such patients. We aimed to assess the safety and efficacy of R-ESG following P-ESG to treat obesity.

Nutrition and physical activity level of adolescents with idiopathic scoliosis: a narrative review.

Some studies have shown that patients with adolescent idiopathic scoliosis (AIS) have different anthropometric features compared with their peers such as taller stature, lower body mass index, and bone mineral density. Yet the causes explaining these differences remain uncertain. Nutritional intake and status, combined with physical activity, could explain these discrepancies.

Mold inhalation causes innate immune activation, neural, cognitive and emotional dysfunction.

Individuals living or working in moldy buildings complain of a variety of health problems including pain, fatigue, increased anxiety, depression, and cognitive deficits. The ability of mold to cause such symptoms is controversial since no published research has examined the effects of controlled mold exposure on brain function or proposed a plausible mechanism of action. Patient symptoms following mold exposure are indistinguishable from those caused by innate immune activation following bacterial or viral exposure.
