Caregivers' hesitancy and outright refusal toward children's COVID-19 vaccination in the Democratic Republic of Congo: A community-based cross-sectional study.

Data from the global South show higher COVID-19-related mortality in children compared to the North. Parents' willingness to vaccinate their children once COVID-19 vaccines are available is poorly documented. We assessed parents' willingness to vaccinate their children in the DRC.

HIV and induced abortion among migrants from sub-Saharan Africa living in Île-de-France: Results of the PARCOURS study.

Introduction: HIV heavily affects sub-Saharan African women living in France and can impact reproductive decisions. It was investigated whether HIV was associated with induced abortion in pregnancies held after migration by women from sub-Saharan Africa living in Île-de-France.

Methods: We used data on ANRS Parcours, a retrospective life event survey conducted in health facilities in the metropolitan region of Paris, between February 2012 and May 2013, with migrants from sub-Saharan Africa.

Effects of variation in exercise training load on cognitive performances and neurotrophic biomarkers in patients with coronary artery disease.

This study compared the effects of linear (LP) and nonlinear (NLP) training periodization on cognitive functions, neurotrophic biomarkers [plasma brain-derived neurotrophic factor (BDNF), insulin-like growth factor-1 (IGF-1)], and cathepsin-B in patients with coronary artery disease (CAD). Forty-four patients with CAD reported to our laboratory on two occasions to undergo testing procedures before and after training sessions, and were then blindly randomized to NLP or LP for 36 training sessions. included blood samples and a maximal cardiopulmonary exercise testing to get maximal oxygen uptake (V̇o).

Integrating very high resolution environmental proxies in genotype-environment association studies.

Landscape genomic analyses associating genetic variation with environmental variables are powerful tools for studying molecular signatures of species' local adaptation and for detecting candidate genes under selection. The development of landscape genomics over the past decade has been spurred by improvements in resolutions of genomic and environmental datasets, allegedly increasing the power to identify putative genes underlying local adaptation in non-model organisms. Although these associations have been successfully applied to numerous species across a diverse array of taxa, the spatial scale of environmental predictor variables has been largely overlooked, potentially limiting conclusions to be reached with these methods.

A Quality Improvement Study on Colonoscopy Wait Times in Underinsured Patients Following the COVID-19 Pandemic.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic limited access to colonoscopy. To advance colorectal cancer health equity, we conducted a quality improvement study on colonoscopy wait times in 2019-2023 for underinsured (Medicaid, uninsured) compared with insured patients at an academic medical center providing colonoscopy for surrounding Federally Qualified Health Centers.

Methods: Retrospective chart reviews were performed on adult outpatient colonoscopies in the preintervention period (2019-2021).

Socio-Demographic Factors Influencing Malaria Vaccine Acceptance for Under-Five Children in a Malaria-Endemic Region: A Community-Based Study in the Democratic Republic of Congo.

Two novel vaccines against malaria are proposed as a complementary control tool to prevent and reduce related disease and death in under-five children from moderate to high malaria transmission regions. The Democratic Republic of Congo (DRC) has committed to eradicate malaria by 2030, and significant efforts have been deployed to strengthen control and elimination measures. We aimed to understand factors influencing the malaria vaccine acceptability among the general population in eastern DRC.

A novel homozygous variant in gene associated with pontocerebellar hypoplasia type 1E: a case report.

Neonatal encephalopathy (NE) is a complex clinical condition with diverse etiologies. Hypoxic-ischemic encephalopathy (HIE) is a major contributor to NE cases. However, distinguishing NE subtypes, such as pontocerebellar hypoplasia type 1E (PCH1E), from HIE can be challenging due to overlapping clinical features.

Vertical distribution and seasonal dynamics of planktonic cyanobacteria communities in a water column of deep mesotrophic Lake Geneva.

Background: Temperate subalpine lakes recovering from eutrophication in central Europe are experiencing harmful blooms due to the proliferation of , a potentially toxic cyanobacteria. To optimize the management of cyanobacteria blooms there is the need to better comprehend the combination of factors influencing the diversity and dominance of cyanobacteria and their impact on the lake's ecology. The goal of this study was to characterize the diversity and seasonal dynamics of cyanobacteria communities found in a water column of Lake Geneva, as well as the associated changes on bacterioplankton abundance and composition.

French healthcare students and antibiotics: are they ready to promote their appropriate use?

Objectives: French healthcare students are required to carry out primary prevention interventions as part of the Healthcare Service by Healthcare Students (HSHS). The purpose of this study was to explore students' perceptions of preparedness to address the public's concerns about antibiotic use and how their perceptions changed after implementing their intervention.

Methods: A questionnaire was sent twice during the 2020-2021 academic year to 920 multidisciplinary healthcare students (nursing, medicine, physiotherapy, pharmacy and midwifery students) enrolled in the HSHS in Franche-Comté (HSHS-FC).

Genomics and conservation: Guidance from training to analyses and applications.

Environmental change is intensifying the biodiversity crisis and threatening species across the tree of life. Conservation genomics can help inform conservation actions and slow biodiversity loss. However, more training, appropriate use of novel genomic methods and communication with managers are needed.

Life cycle assessment of municipal biowaste management - a Czech case study.

As part of coming targets to transition to a sustainable society and actively set a circular economy, one of the EU objectives is to decrease the amount of municipal solid waste and initiate the separation of its organic fraction, i.e., biowaste.

Distractor-induced saccade trajectory curvature reveals visual contralateral bias with respect to the dominant eye.

The functional consequences of the visual system lateralization referred to as "eye dominance" remain poorly understood. We previously reported shorter hand reaction times for targets appearing in the contralateral visual hemifield with respect to the dominant eye (DE). Here, we further explore this contralateral bias by studying the influence of laterally placed visual distractors on vertical saccade trajectories, a sensitive method to assess visual processing.

Validation Criteria for PCO Kinetics during the Hyperventilation Provocation Test in the Diagnosis of Idiopathic Hyperventilation Syndrome.

Background: The hyperventilation provocation test (HPTest) is a diagnostic tool for idiopathic hyperventilation syndrome (HVS), encountered in some long-COVID patients. However, interpretation of the HPTest remains unclear regarding the relevant PETCO2 values to focus on and whether subjective symptoms should be considered. This study aimed to re-evaluate objective HPTest results for diagnosing HVS by determining accurate PETCO2 kinetics in two groups of patients previously screened via the Nijmegen questionnaire (NQ).

A High-Throughput Search for SFXN1 Physical Partners Led to the Identification of ATAD3, HSD10 and TIM50.

Sideroflexins (SFXN, SLC56) are a family of evolutionarily conserved mitochondrial carriers potentially involved in iron homeostasis. One member of the SFXN family is SFXN1, recently identified as a human mitochondrial serine transporter. However, little is known about the SFXN1 interactome, necessitating a high-throughput search to better characterize SFXN1 mitochondrial functions.

Symptomatic Colorectal Cancer Is Associated With Stage IV Diagnosis in Two Disparate Populations.

In the United States, individuals of Black/African Ancestry (AA) have a higher incidence and mortality from colorectal cancer (CRC) compared to individuals of White/European Ancestry (EA). In order to develop an approach towards disentangling the complex effects of associated race and socioeconomic factors on CRC outcome, we have conducted a manual chart review of sporadic CRC pathological diagnoses (total n = 334) at an urban public hospital (UH) and a suburban university hospital (SH). There were significant differences between the SH and UH CRC patients with respect to Black/AA race (4.

The Terrestrial Biosphere Model Farm.

Model Intercomparison Projects (MIPs) are fundamental to our understanding of how the land surface responds to changes in climate. However, MIPs are challenging to conduct, requiring the organization of multiple, decentralized modeling teams throughout the world running common protocols. We explored centralizing these models on a single supercomputing system.

Black voices in gastroenterology and hepatology.

The Association of Black Gastroenterologists and Hepatologists (ABGH) was established to improve health equity in Black communities and to provide academic and social support for Black gastroenterologists and hepatologists. In this Viewpoint, four members of ABGH (early career, mid-career and late career) discuss their route into gastroenterology and hepatology, how academia and medicine can promote inclusivity and equity, and their advice to Black students interested in a career in medicine or science.

The Struggling Odyssey of Infantile Primary Hyperoxaluria.

Oxalate overproduction in Primary Hyperoxaluria type I (PH1) leads to progressive renal failure and systemic oxalate deposition. In severe infantile forms of PH1 (IPH1), end-stage renal disease (ESRD) occurs in the first years of life. Usually, the management of these infantile forms is challenging and consists in an intensive dialysis regimen followed by a liver-kidney transplantation (combined or sequential).

Characterization of a novel strain of Aspergillus aculeatinus: From rhamnogalacturonan type I pectin degradation to improvement of fruit juice filtration.

Aspergillus spp. are well-known producers of pectinases commonly used in the industry. Aspergillus aculeatinus is a recently identified species but poorly characterized.

Combined Deletion of Free Fatty-Acid Receptors 1 and 4 Minimally Impacts Glucose Homeostasis in Mice.

The free fatty-acid receptors FFAR1 (GPR40) and FFAR4 (GPR120) are implicated in the regulation of insulin secretion and insulin sensitivity, respectively. Although GPR120 and GPR40 share similar ligands, few studies have addressed possible interactions between these 2 receptors in the control of glucose homeostasis. Here we generated mice deficient in gpr120 (Gpr120KO) or gpr40 (Gpr40KO), alone or in combination (Gpr120/40KO), and metabolically phenotyped male and female mice fed a normal chow or high-fat diet.

Insights into the Roles of the Sideroflexins/SLC56 Family in Iron Homeostasis and Iron-Sulfur Biogenesis.

Sideroflexins (SLC56 family) are highly conserved multi-spanning transmembrane proteins inserted in the inner mitochondrial membrane in eukaryotes. Few data are available on their molecular function, but since their first description, they were thought to be metabolite transporters probably required for iron utilization inside the mitochondrion. Such as numerous mitochondrial transporters, sideroflexins remain poorly characterized.

Free fatty acid receptor 4 inhibitory signaling in delta cells regulates islet hormone secretion in mice.

Objective: Maintenance of glucose homeostasis requires the precise regulation of hormone secretion from the endocrine pancreas. Free fatty acid receptor 4 (FFAR4/GPR120) is a G protein-coupled receptor whose activation in islets of Langerhans promotes insulin and glucagon secretion and inhibits somatostatin secretion. However, the contribution of individual islet cell types (α, β, and δ cells) to the insulinotropic and glucagonotropic effects of GPR120 remains unclear.

Achalasia: physiology and diagnosis.

Achalasia is a rare motility disorder with incomplete relaxation of the lower esophageal sphincter and ineffective contractions of the esophageal body. It has been hypothesized that achalasia does not result from only one pathway but rather involves a combination of infectious, autoimmune, and familial etiological components. On the basis of other observations, a novel hypothesis suggests that a muscular form of eosinophilic esophagitis is involved in the pathophysiology of achalasia in some patients.

Three novel rhamnogalacturonan I- pectins degrading enzymes from Aspergillus aculeatinus: Biochemical characterization and application potential.

Rhamnogalaturonans I (RGI) pectins, which are a major component of the plant primary cell wall, can be recalcitrant to digestion by commercial enzymatic cocktails, in particular during fruit juice clarification process. To overcome these problems and get better insights into RGI degradation, three RGI degrading enzymes (RHG: Endo-rhamnogalacturonase; ABF: α-Arabinofuranosidases; GAN: Endo-β-1,4-galactanase) from Aspergillus aculeatinus were expressed in Pichia pastoris, purified and fully biochemically characterized. All three enzymes showed acidic pH optimum, and temperature optima between 40-50 °C.
