Article Synopsis
  • - The study analyzed bone density and fracture risks between 1,427 male veterans and matched non-veterans, revealing that veterans have a higher overall fracture risk and higher post-fracture mortality rates.
  • - Veterans were found to be slightly younger when experiencing fractures and had better bone density scores in certain areas compared to non-veterans; however, they also had a greater incidence of radial fractures.
  • - The findings highlight the need for targeted medical interventions for veterans due to their higher rates of comorbidities and increased mortality after fractures, emphasizing the importance of prevention and long-term care in osteoporosis management.

Unlabelled: The mosquito plays a critical role in the transmission of viral diseases, including Zika virus, which poses significant public health challenges. Understanding the complex interactions between mosquitoes and viruses is paramount for the development of effective control strategies. In this study, we demonstrate that silencing the adiponectin receptor-like protein (AaARLP) results in a reduction of Zika virus infection.

Article Synopsis
  • Mosquito saliva, particularly a protein called Nest1, modifies the human immune response to enhance blood feeding and increase the likelihood of pathogen spread, such as Zika virus.
  • Nest1 interacts with a human protein known as CD47, which plays a role in immune processes, and this interaction appears to suppress the body’s ability to mount an effective antiviral response.
  • By outcompeting the natural ligand for CD47, Nest1 hinders phagocytosis and reduces inflammation, thereby facilitating the dissemination of Zika virus in human skin.

The midgut is crucial for blood digestion, nutrition, reproduction, and pathogen interaction. Using single-cell RNA sequencing, we explored virus infection and transcriptomic changes at the cellular level. We identified 12 distinct cell clusters in the midgut post-Zika virus infection, including intestinal stem cells, enteroblasts, enteroendocrine cells (EE), and enterocytes (ECs).

: Cervical disc herniation (CDH) leads to pain, numbness, and potential disability. Percutaneous endoscopic cervical discectomy (PECD) offers an anterior or posterior approach. This study aims to compare postoperative disc height and angle changes one year after PECD, considering both approaches.

Objective: This retrospective study was designed to evaluate the incidence and predisposing factors of heterotopic ossification (HO) after cervical disc arthroplasty (CDA) with a specific implant at 1 and 2 levels, and to investigate the biomechanical effects related to HO. The study goal was to identify ways to reduce the likelihood of HO formation after surgery.

Methods: The study included patients who underwent only 1- or 2-level CDA with the Baguera C disc between November 2014 and December 2021 at a single medical center.

Article Synopsis
  • - This study investigated the genetic factors affecting survival duration in Glioblastoma Multiforme (GBM) patients using Next-Generation Sequencing, dividing 30 patients into extended (over two years) and abbreviated (under two years) survival groups.
  • - Key mutations identified included CHEK2, IDH1, and TP53, with non-coding variants found in TERT and TP53 RNA splicing sites, although no statistical significance was reached due to the small sample size.
  • - Interestingly, TP53 mutations were more common in the longer-surviving group, challenging previous Western findings; however, further research is necessary to explore their functional implications and the role of other mutations in therapeutic strategies.

S-adenosylmethionine (SAM), generated from methionine and ATP by S-adenosyl methionine synthetase (SAMS), is the universal methyl group donor required for numerous cellular methylation reactions. In Caenorhabditis elegans, silencing sams-1, the major isoform of SAMS, genetically or via dietary restriction induces a robust mitochondrial unfolded protein response (UPR) and lifespan extension. In this study, we found that depleting SAMS-1 markedly decreases mitochondrial SAM levels.

Article Synopsis
  • The study examines the effects of a hybrid stabilization system (DTO) on adjacent segment disease (ASD) in patients with lumbar spinal stenosis and spondylolisthesis.
  • From 2012 to 2020, 31 out of 115 patients were analyzed, with follow-ups measuring various spinal changes at key segments over two years.
  • Results showed that while ASD was not significantly prevented, the L3-L4 segment demonstrated reduced motion changes and less degeneration compared to adjacent segments, indicating a potential benefit of DTO in stabilizing that level.

Article Synopsis
  • An estimated 88% of rheumatoid arthritis (RA) patients deal with cervical spine issues, specifically atlantoaxial instability (AAI), which can complicate surgical procedures.
  • This study reviewed 20 years of surgeries on 67 AAI patients, employing advanced techniques like fluoroscopy, surgical navigation, and augmented reality to enhance surgical accuracy.
  • The findings suggest that using CT-based image-guided surgery and augmented reality can significantly improve the outcomes of C1-C2 surgeries, especially for RA patients facing technical challenges.

Objectives: Heterotopic ossification (HO), a major cause of dysfunction after disc arthroplasty (CDA). The aim of this study was to determine the cut value of the residual exposed endplate (REE) ratio and to predict the development of posterior HO after Bryan CDA.

Methods: This retrospective study investigated the relationship between the REE ratio and posterior HO formation after Bryan CDA.

Arthropod-borne viruses present important public health challenges worldwide. Viruses such as DENV, ZIKV, and WNV are of current concern due to an increasing incidence and an expanding geographic range, generating explosive outbreaks even in non-endemic areas. The clinical signs associated with infection from these arboviruses are often inapparent, mild, or nonspecific, but occasionally develop into serious complications marked by rapid onset, tremors, paralysis, hemorrhagic fever, neurological alterations, or death.

Objectives: The objectives of this study were to identify the risk factors and incidence of anterior bone loss (ABL) after Baguera C cervical disc arthroplasty (CDA) and identify whether design differences in artificial discs affect ABL.

Methods: In this retrospective radiological review of patients who underwent single-level Baguera C CDA in a medical center, the extent of ABL and the following radiological parameters were recorded: global and segmental alignment angle, lordotic angle (or functional spinal unit angle), shell angle, global range of motion (ROM), and ROM of the index level. ABL at the index level was grade 0-2.

Background: Mosquito-borne dengue virus (DENV) causes major disease worldwide, impacting 50-100 million people every year, and is spread by the major mosquito vector Aedes aegypti. Understanding mosquito physiology, including antiviral mechanisms, and developing new control strategies have become an important step towards the elimination of DENV disease. In the study reported here, we focused on autophagy, a pathway suggested as having a positive influence on virus replication in humans, as a potential antiviral target in the mosquito.

Florida lies within a subtropical region where the climate allows diverse mosquito species including invasive species to thrive year-round. As of 2021, there are currently 66 state-approved Florida Mosquito Control Districts, which are major stakeholders for Florida public universities engaged in mosquito research. Florida is one of the few states with extensive organized mosquito control programs.

Background: Dopamine agonists such as bromocriptine and cabergoline have been found to be an effective treatment for hyperprolactinemia, not only inducing adenoma shrinkage but also lowering serum prolactin levels. Among known dopamine agonists, cabergoline is the drug of choice due to its enhanced tolerability compared with bromocriptine. This study aimed to evaluate cabergoline's effectiveness, along with transsphenoidal surgery, in the treatment of hyperprolactinemia.

A recently published DNA extraction protocol using magnetic beads and an automated DNA extraction instrument suggested that it is possible to extract high quality and quantity DNA from a well-preserved individual mosquito sufficient for downstream whole genome sequencing. However, reliance on an expensive automated DNA extraction instrument can be prohibitive for many laboratories. Here, the study provides a budget-friendly magnetic-bead-based DNA extraction protocol, which is suitable for low to medium throughput.
