Bone Regeneration: Mini-Review and Appealing Perspectives.

Bone is a natural mineral-organic nanocomposite protecting internal organs and allowing mobility. Through the ages, numerous strategies have been developed for repairing bone defects and fixing fractures. Several generations of bone repair biomaterials have been proposed, either based on metals, ceramics, glasses, or polymers, depending on the clinical need, the maturity of technologies, and knowledge of the natural constitution of the bone tissue to be repaired.

Sex disparities in ICU care and outcomes after cardiac arrest: a Swiss nationwide analysis.

Objective: To provide prevalence estimates of any, no more than 4, or fewer than 2 CMBs in association with amyloid status, APOE ε4 copy number, and age.

Design, Setting, And Participants: This cross-sectional study used data included in the Amyloid Biomarker Study data pooling initiative (January 1, 2012, to the present [data collection is ongoing]).

Lipophilic molecular rotor to assess the viscosity of oil core in nano-emulsion droplets.

Characterization of nanoscale formulations is a continuous challenge. Size, morphology and surface properties are the most common characterizations. However, physicochemical properties inside the nanoparticles, like viscosity, cannot be directly measured.

Biomarkers of sepsis-induced coagulopathy: diagnostic insights and potential therapeutic implications.

Diagnosing coagulopathy in septic patients remains challenging in intensive care. Disseminated intravascular coagulation (DIC) indeed presents with complex pathophysiology, complicating timely diagnosis. Epidemiological data indicate a significant prevalence of DIC in septic patients, with mortality rates up to 60%.

Impact of hyper- and hypothermia on cellular and whole-body physiology.

The incidence of heat-related illnesses and heatstroke continues to rise amidst global warming. Hyperthermia triggers inflammation, coagulation, and progressive multiorgan dysfunction, and, at levels above 40 °C, can even lead to cell death. Blood cells, particularly granulocytes and platelets, are highly sensitive to heat, which promotes proinflammatory and procoagulant changes.

Mitochondrial dysfunction is a major cause of thromboinflammation and inflammatory cell death in critical illnesses.

Background: Mitochondria generate the adenosine triphosphate (ATP) necessary for eukaryotic cells, serving as their primary energy suppliers, and contribute to host defense by producing reactive oxygen species. In many critical illnesses, including sepsis, major trauma, and heatstroke, the vicious cycle between activated coagulation and inflammation results in tissue hypoxia-induced mitochondrial dysfunction, and impaired mitochondrial function contributes to thromboinflammation and cell death.

Methods: A computer-based online search was performed using the PubMed and Web of Science databases for published articles concerning sepsis, trauma, critical illnesses, cell death, mitochondria, inflammation, coagulopathy, and organ dysfunction.

Evaluating the factor structure of the Wechsler Adult Intelligence Scale, Fourth Edition (WAIS-IV) in adults with congenital heart disease.

: While it is generally assumed that common neurobehavioral assessments, such as the Wechsler Adult Intelligence Scale, Fourth Edition (WAIS-IV), function similarly in clinical and non-clinical populations, this has not been validated in adults with congenital heart disease (CHD). In this study, we examined the latent factor structure of the WAIS-IV in adults with d-transposition of the great arteries (d-TGA) who participated in the Boston Circulatory Arrest Study. : The WAIS-IV was administered as part of a larger assessment battery.

The prohibitin ligand IN44 decreases Porphyromonas gingivalis mediated inflammation.

Background: Periodontitis is an inflammatory disease causing destruction of periodontal tissues. Controlling inflammation is crucial for periodontitis treatment. Prohibitins (PHBs) are emerging targets in the treatment of inflammatory diseases.

Oral invasive procedures in Glanzmann thrombasthenia: a retrospective observational study.

Background: Glanzmann thrombasthenia (GT) is a very rare autosomal inherited bleeding disease affecting megakaryocyte lineage with impacts on oral health such as gingival bleeding, which requires specific management protocols. Very few clinical cases have been published in the dental and hematologic literature.

Objectives: This study focuses on a series of 21 patients affected specifically by GT and their hemorrhagic prophylaxis management with the use of recombinant activated factor VII (rFVIIa) for dental extractions and full-mouth debridement.

Managing linguistic obstacles in multidisciplinary, multinational, and multilingual research projects.

Environmental challenges are rarely confined to national, disciplinary, or linguistic domains. Convergent solutions require international collaboration and equitable access to new technologies and practices. The ability of international, multidisciplinary and multilingual research teams to work effectively can be challenging.

Daily cigarette smoking among inpatients for substance use disorders in France, 2010-2020: Commonalities and specificities across substances.

Introduction: This study aims to estimate the prevalence and factors associated with cigarette smoking among patients in treatment for substance use disorders (SUD) in France.

Methods: We analyze a nation-wide dataset retrieving information on patients entering treatment for alcohol, opioid and stimulant use disorders between 2010 and 2020. We conduct multilevel Poisson regressions to determine the main factors associated with daily cigarette smoking among all patients who entered treatment for alcohol (n=607122), opioid (n=283381) or stimulant (n=57189) use disorders, and zero-truncated negative-binomial regressions to predict the average number of cigarettes per day.

The state-of-the-art of N-of-1 therapies and the IRDiRC N-of-1 development roadmap.

In recent years, a small number of people with rare diseases caused by unique genetic variants have been treated with therapies developed specifically for them. This pioneering field of genetic N-of-1 therapies is evolving rapidly, giving hope for the individualized treatment of people living with very rare diseases. In this Review, we outline the concept of N-of-1 individualized therapies, focusing on genetic therapies, and illustrate advances and challenges in the field using cases for which therapies have been successfully developed.

Prevention of Sunlight-Induced Cell Damage by Selective Blue-Violet-Light-Filtering Lenses in A2E-Loaded Retinal Pigment Epithelial Cells.

Blue light accelerates retinal aging. Previous studies have indicated that wavelengths between 400 and 455 nm are most harmful to aging retinal pigment epithelia (RPE). This study explored whether filtering these wavelengths can protect cells exposed to broad sunlight.

Autophagy and autophagic cell death in sepsis: friend or foe?

In sepsis, inflammation, and nutrient deficiencies endanger cellular homeostasis and survival. Autophagy is primarily a mechanism of cellular survival under fasting conditions. However, autophagy-dependent cell death, known as autophagic cell death, is proinflammatory and can exacerbate sepsis.

Optimising Paediatric HIV Treatment: Recent Developments and Future Directions.

Treatment options for children living with HIV have historically been less effective, less practical and more difficult to implement compared with those for adults, as the research and development of new drugs for children has lagged behind. Significant progress has been achieved in response to the paediatric HIV epidemic over the last decade. Several optimised paediatric antiretroviral formulations are currently available or in development, including fixed-dose combination tablets containing a complete World Health Organization-recommended regimen.

Leaving no patient behind! Expert recommendation in the use of innovative technologies for diagnosing rare diseases.

Genetic diagnosis plays a crucial role in rare diseases, particularly with the increasing availability of emerging and accessible treatments. The International Rare Diseases Research Consortium (IRDiRC) has set its primary goal as: "Ensuring that all patients who present with a suspected rare disease receive a diagnosis within one year if their disorder is documented in the medical literature". Despite significant advances in genomic sequencing technologies, more than half of the patients with suspected Mendelian disorders remain undiagnosed.
