Xolography for Biomedical Applications: Dual-Color Light-Sheet Printing of Hydrogels With Local Control Over Shape and Stiffness.

Current challenges in tissue engineering include creation of extracellular environments that support and interact with cells using biochemical, mechanical, and structural cues. Spatial control over these cues is currently limited due to a lack of suitable fabrication techniques. This study introduces Xolography, an emerging dual-color light-sheet volumetric printing technology, to achieve control over structural and mechanical features for hydrogel-based photoresins at micro- to macroscale while printing within minutes.

Practical Recommendations for the Diagnosis and Management of Lysosomal Acid Lipase Deficiency with a Focus on Wolman Disease.

Lysosomal acid lipase deficiency (LAL-D) is an ultra-rare lysosomal storage disease with two distinct phenotypes, an infantile-onset form (formerly Wolman disease) and a later-onset form (formerly cholesteryl ester storage disease). The objective of this narrative review is to examine the most important aspects of the diagnosis and treatment of LAL-D and to provide practical expert recommendations. The infantile-onset form occurs in the first weeks of life and is characterized by malnourishment and failure to thrive due to gastrointestinal impairment (vomiting, diarrhea, malabsorption), as well as systemic inflammation, hepatosplenomegaly, and adrenal calcifications.

Racial/Ethnic Disparities in Oncology Clinical Trial Participation: Investigator Attitudes, Needs, and Motivation to Improve.

Purpose: The perspective of all stakeholders involved in clinical trials is critical to addressing disparities in racial/ethnic minority (REM) clinical trial participation. Little is known about clinical trial investigator perspectives. To our knowledge, there are no published studies assessing differences in investigator perspectives on the basis of their primary role in clinical trials (ie, principal investigator [PI] or subinvestigator [sub-I]).

Limitations With California Medicaid Data for Palliative and End of Life Care Quality Measures.

In 2014 the California legislature passed Senate Bill 1004 (SB 1004) that was designed to expand access to specialty palliative care for individuals served by California's Medicaid (known as Medi-Cal) Managed Care Plans (MCPs). The California Department of Health Care Services (DHCS) operationalized the legislation by developing minimum requirements for palliative care programs that all MCPs must meet or exceed. Quality and utilization data specific to California's Medicaid population are needed for stakeholders to identify care deficiencies and disparities, describe the end of life experience and utilization patterns of MCP members, compare these patterns to Medicare beneficiaries or other populations, and set appropriate targets to help monitor progress.

Caring for others without neglecting oneself? Grandparent caregivers, gender, and perceived health-related quality of life.

In this study, we explored the impact of caregiving on quality of life and health perceptions and outlined the profile of grandparent caregivers in Andalusia (Spain) in terms of a range of sociodemographic variables related to the care of their grandchildren. A sample of 171 participants (21.6% men) completed the Health-Related Quality of Life (HRQoL) questionnaire and another ad hoc one providing sociodemographic and caregiving data.

Synthesis and interaction with growth factors of sulfated oligosaccharides containing an anomeric fluorinated tail.

Compounds that mimic the biological properties of glycosaminoglycans (GAGs) and can be more easily prepared than the native GAG oligosaccharides are highly demanded. Here, we present the synthesis of sulfated oligosaccharides displaying a perfluorinated aliphatic tag at the reducing end as GAG mimetics. The preparation of these molecules was greatly facilitated by the presence of the fluorinated tail since the reaction intermediates were isolated by simple fluorous solid-phase extraction.

Infections and risk factors for infection-related mortality after pediatric allogeneic hematopoietic stem cell transplantation in Mexico: A single center retrospective study.

Objective: To identify the type of infections and risk factors for infection-related mortality (IRM) after allogeneic hematopoietic stem cell transplantation (HSCT).

Methods: Retrospective cohort study of patients <16 years of age treated in 2010-2019 was conducted. Unadjusted hazard ratios (HR) and adjusted hazard ratios (aHR) with 95% confidence intervals (95% CIs) were estimated using Cox regression.

Effective Coping with Academic Stress Is a Matter of Personality Types: Revisiting the Person-Centred Approach.

Recent literature provides alarming data on the increase in university academic stress. The role of personality in understanding and addressing this problem is well established. However, this evidence could be improved by adopting a person-centred approach (e.

Consent document translation expense hinders inclusive clinical trial enrolment.

Patients from historically under-represented racial and ethnic groups are enrolled in cancer clinical trials at disproportionately low rates in the USA. As these patients often have limited English proficiency, we hypothesized that one barrier to their inclusion is the cost to investigators of translating consent documents. To test this hypothesis, we evaluated more than 12,000 consent events at a large cancer centre and assessed whether patients requiring translated consent documents would sign consent documents less frequently in studies lacking industry sponsorship (for which the principal investigator pays the translation costs) than for industry-sponsored studies (for which the translation costs are covered by the sponsor).

Using machine learning-based systems to help predict disengagement from the legal proceedings by women victims of intimate partner violence in Spain.

Intimate partner violence against women (IPVW) is a pressing social issue which poses a challenge in terms of prevention, legal action, and reporting the abuse once it has occurred. However, a significant number of female victims who file a complaint against their abuser and initiate legal proceedings, subsequently, withdraw charges for different reasons. Research in this field has been focusing on identifying the factors underlying women victims' decision to disengage from the legal process to enable intervention before this occurs.

Prediction of patients with idiopathic generalized epilepsy from healthy controls using machine learning from scalp EEG recordings.

Epilepsy detection is essential for patients with epilepsy and their families, as well as for researchers and medical staff. The use of electroencephalogram (EEG) as a tool to support the diagnosis of patients with epilepsy is fundamental. Today, machine learning (ML) techniques are widely applied in neuroscience.

The Interaction between Chondroitin Sulfate and Dermatan Sulfate Tetrasaccharides and Pleiotrophin.

Pleiotrophin (PTN) is a neurotrophic factor that participates in the development of the embryonic central nervous system (CNS) and neural stem cell regulation by means of an interaction with sulfated glycosaminoglycans (GAGs). Chondroitin sulfate (CS) is the natural ligand in the CNS. We have previously studied the complexes between the tetrasaccharides used here and MK (Midkine) by ligand-observed NMR techniques.

Development and characterization of cell models harbouring mtDNA deletions for in vitro study of Pearson syndrome.

Pearson syndrome is a rare multisystem disease caused by single large-scale mitochondrial DNA deletions (SLSMDs). The syndrome presents early in infancy and is mainly characterised by refractory sideroblastic anaemia. Prognosis is poor and treatment is supportive, thus the development of new models for the study of Pearson syndrome and new therapy strategies is essential.
