Our goal was to test the effectiveness of collaborative care (CC) versus usual care (UC) to improve treatment of pain, depression, physical inactivity, and quality of life in outpatients with spinal cord injury (SCI). We conducted a single blind parallel group randomized controlled trial. The setting was two outpatient SCI rehabilitation clinics within a large academic medical center. Participants were 174 outpatients who were on average 47.7 years old, 76% male, 76% white, 8% Hispanic, 47%...

Modeling blood flow in aneurysms treated with coils could be used to understand the complete embolization of the aneurysm, through thrombus formation that fills the entire sac. Modeling of the endovascular coil mass as a porous medium is a technique that allows for study of aneurysm hemodynamics, efficiently for patient-specific treatment outcome predictions. Models in the literature use mean porosity of coils in the aneurysmal volume, proving inadequate for outcome prediction. However, models...

CONCLUSION: A summary of this evidence reveals a lower short-term mortality in hemodynamically stable patients with mesenteric malperfusion, along with a reduction in postoperative laparotomy/bowel resections. Of those patients who survive to receive central repair, short-term mortality remains very low in the select group of hemodynamically stable patients. Further high-quality studies with randomized or propensity matched data are required to verify these results.

CONCLUSIONS: Proximal and distal occlusions with low NIHSS have comparable outcomes and safety profiles. While all MT techniques have a similar safety profile, ADAPT was associated with better clinical outcomes at discharge and 90 days.

CONCLUSIONS: These findings uncover a novel pathway for Lp(a) endocytosis involving multiple plasminogen receptors that enhance surface binding and stimulate macropinocytosis of Lp(a). Although the findings were produced in cell culture models that have limitations, they could have clinical relevance since drugs that inhibit macropinocytosis are in clinical use, that is, the PI3K inhibitors for cancer therapy and some antidepressant compounds.

CONCLUSIONS: Self-reported Executive Dysfunction contributed to participation outcomes after mild to severe TBI in community-dwelling adults, whereas self-reported emotional and fatigue symptoms did not. Performance-based cognition measures may capture different variability in participation after injury.

INTRODUCTION: Malaria, a devastating febrile illness caused by protozoan parasites, sickened 247,000,000 people in 2021 and killed 619,000, mostly children and pregnant women in sub-Saharan Africa. A highly effective vaccine is urgently needed, especially for Plasmodium falciparum (Pf), the deadliest human malaria parasite.

Development of next-generation vaccines against Plasmodium falciparum (Pf) is a priority. Many malaria vaccines target the pre-erythrocytic sporozoite (SPZ) and liver stages. These include subunit vaccines based on the Pf circumsporozoite protein (CSP) and attenuated PfSPZ vaccines. However, these strategies require 3-4 doses and have not achieved optimal efficacy against field-transmitted malaria. Prime-and-trap is a recently developed two-step heterologous vaccine strategy that combines...

CONCLUSION: We present a pair of ischaemic and bleeding risk scores specifically to assist clinicians and their patients in deciding on DAPT duration beyond the first month post-ACS.

In this study, we leveraged the combined evidence of rare coding variants and common alleles to identify therapeutic targets for osteoporosis. We undertook a large-scale multiancestry exome-wide association study for estimated bone mineral density, which showed that the burden of rare coding alleles in 19 genes was associated with estimated bone mineral density (P < 3.6 × 10^(-7)). These genes were highly enriched for a set of known causal genes for osteoporosis (65-fold; P = 2.5 × 10^(-5))....

CONCLUSIONS: This review demonstrates the durability and safety of the David and Yacoub valve-sparing procedures across long-term follow-up in bicuspid aortic valve patients. These procedures offer significant freedom from mortality and secondary reoperations on the aorta and valve and will likely continue to demonstrate excellent results into the future. There is a clear transition towards the David procedure, with the bulk of contemporary literature publishing on this technique.

There is increasing interest in the African spiny mouse (Acomys cahirinus) as a model organism because of its ability for regeneration of tissue after injury in skin, muscle, and internal organs such as the kidneys. A high-quality reference genome is needed to better understand these regenerative properties at the molecular level. Here, we present an improved reference genome for A. cahirinus generated from long Nanopore sequencing reads. We confirm the quality of our annotations using RNA...

CONCLUSIONS-: Our results have implications for the development of interventional strategies after ischemic stroke and suggest a novel potential modality of therapy after mechanical thrombectomy.

CONCLUSIONS: TM in SUD treatment is generally perceived to be beneficial and acceptable and as effective as in-person care, although more rigorously designed studies on effectiveness are still lacking. Access and utilization of TM may vary by platform. TM service quality and costs are the least studied and warrant further investigations.

The accepted paradigm for both cellular and anti-tumor immunity relies upon tumor cell killing by CD8^(+) T cells recognizing cognate antigens presented in the context of target cell major histocompatibility complex (MHC) class I (MHC-I) molecules. Likewise, a classically described mechanism of tumor immune escape is tumor MHC-I downregulation. Here, we report that CD8^(+) T cells maintain the capacity to kill tumor cells that are entirely devoid of MHC-I expression. This capacity proves to be...

CONCLUSIONS: There is varied opinion on what we should prioritise in measuring the experience in simulation practice. Importantly, this study identified key areas that aids our understanding on how we can measure new technology in educational settings. Synthesising these results in to a multidomain instrument requires a systematic approach to testing in future research.

Cerebral aneurysms are a serious clinical challenge, with ∼half resulting in death or disability. Treatment via endovascular coiling significantly reduces the chances of rupture, but the techniquehas failure rates of ∼20 %. This presents a pressing need to develop a method fordetermining optimal coildeploymentstrategies. Quantification of the hemodynamics of coiled aneurysms using computational fluid dynamics (CFD) has the potential to predict post-treatment outcomes, but representing the coil...

CONCLUSION: This study demonstrated supranormal fecal elastase levels and weight gain posttransplant; however, there was no correlation. Future study with serial FE-1 before and after transplant is needed to better assess its correlation with weight gain.

The expression of the placental growth factor (PGF) in cancer cells and the tumor microenvironment can contribute to the induction of angiogenesis, supporting cancer cell metabolism by ensuring an adequate blood supply. Angiogenesis is a key component of cancer metabolism as it facilitates the delivery of nutrients and oxygen to rapidly growing tumor cells. PGF is recognized as a novel target for anti-cancer treatment due to its ability to overcome resistance to existing angiogenesis inhibitors...
