Bilateral lung volume reduction surgery outperforms the unilateral approach in functional improvement.

Objectives: Lung volume reduction surgery (LVRS) is an established treatment approach for patients with severe pulmonary emphysema, enhancing lung function and quality of life in selected patients. Functional benefits and outcomes after uni- versus bilateral lung volume reduction remain a topic of debate.

Methods: A retrospective analysis of patients undergoing LVRS from January 2018 to October 2022 was conducted.

Association between infection, mismatch repair, HER2 and tumor-infiltrating lymphocytes in gastric cancer.

Background: The influence of () infection and the characteristics of gastric cancer (GC) on tumor-infiltrating lymphocyte (TIL) levels has not been extensively studied. Analysis of infiltrating-immune-cell subtypes as well as survival is necessary to obtain comprehensive information.

Aim: To determine the rates of deficient mismatch-repair (dMMR), HER2-status and infection and their association with TIL levels in GC.

Wald χ Test for Differential Item Functioning Detection with Polytomous Items in Multilevel Data.

Identifying items with differential item functioning (DIF) in an assessment is a crucial step for achieving equitable measurement. One critical issue that has not been fully addressed with existing studies is how DIF items can be detected when data are multilevel. In the present study, we introduced a Lord's Wald test-based procedure for detecting both uniform and non-uniform DIF with polytomous items in the presence of the ubiquitous multilevel data structure.

Functional outcomes in MRI-guided laser interstitial therapy for temporal lobe epilepsy: a systematic review and meta-analysis.

Objective: The use of MRI-guided laser interstitial thermal therapy (MRgLITT) has emerged as a promising treatment option for patients with drug-resistant temporal lobe epilepsy (TLE). Although the minimally invasive approach holds promise as an effective treatment for achieving seizure freedom, a comprehensive review of its impact on functional outcomes is still warranted. To address this need, this review aims to summarize data pertaining to the functional and neurocognitive outcomes following MRgLITT for TLE.

The longitudinal relationship between levels of cognitively stimulating leisure activity and positive and negative affect among older adults with MCI.

Background: The purpose of this study was to investigate the longitudinal relationship between different levels of cognitively stimulating leisure activity (CSLA) participation and different levels of positive and negative affect among older adults with mild cognitive impairment (MCI).

Methods: Using a repeated-measured multivariate analysis of covariance (RM-MANCOVA), this study analyzed the Health and Retirement Study (HRS) data from 2012 to 2020 (N = 5932).

Results: The results presented the following.

Brain abscesses following carotid blowout syndrome: a case report.

We report a case of intracranial abscesses development in a patient with head and neck cancer after emergent treatment of carotid blowout syndrome with coil embolization. Our patient is a 60-year-old male who presented with hemoptysis and hematemesis, which raised concerns for impending carotid blowout syndrome. Endovascular occlusion was successfully achieved, and the patient was discharged in stable condition.

Unilateral optogenetic kindling of hippocampus leads to more severe impairments of the inhibitory signaling in the contralateral hippocampus.

The kindling model has been used extensively by researchers to study the neurobiology of temporal lobe epilepsy (TLE) due to its capacity to induce intensification of seizures by the progressive recruitment of additional neuronal clusters into epileptogenic networks. We applied repetitive focal optogenetic activation of putative excitatory neurons in the dorsal CA1 area of the hippocampus of mice to investigate the role of inhibitory signaling during this process. This experimental protocol resulted in a kindling phenotype that was maintained for 2 weeks after the animals were fully kindled.

Intraventricular endoscopy and intraventricular antibiotics in the treatment of multiloculated hydrocephalus with ventriculitis in a neonate and an infant: Two case reports.

Background: We present two pediatric cases, a neonate and an infant, who presented with treatment-refractory ventriculitis and multiloculated hydrocephalus treated with simultaneous intraventricular endoscopy and antibiotics. This is the first report of this combined therapy in children.

Case Description: Using intraventricular endoscopic surgery and antibiotics, hydrocephalus was treated with a minimum number of ventricular shunt systems.

Ischemic Stroke in a Seven-Year-Old Female With Down Syndrome and Newly Discovered Moyamoya Syndrome.

Moyamoya represents a rare, progressive cerebrovascular disease, characterized by a gradual stenosis of the intracranial internal carotid arteries, thereby increasing the risk of stroke. Down syndrome is known to be a predisposing factor for Moyamoya syndrome. This review discusses a distinctive case of a seven-year-old female with Down syndrome who manifested with Moyamoya syndrome, evident from acute stroke-like symptoms.

The importance of the pretreatment of samples in Nd quantification from NdFeB magnets through inductively coupled plasma atomic emission spectroscopy (ICP-OES)-a rapid and streamlined methodology.

In this study, we emphasize the critical role of sample pretreatment. We report on the behavior of NdFeB magnet samples exposed to four different acid media for digestion. NdFeB magnets are becoming a significant source of neodymium, a rare-earth element critical to many technologies and a potential substitute for traditional mining of the element.

Ictogenesis proceeds through discrete phases in hippocampal CA1 seizures in mice.

Epilepsy is characterized by spontaneous non-provoked seizures, yet the mechanisms that trigger a seizure and allow its evolution remain underexplored. To dissect out phases of ictogenesis, we evoked hypersynchronous activity with optogenetic stimulation. Focal optogenetic activation of putative excitatory neurons in the mouse hippocampal CA1 reliably evoked convulsive seizures in awake mice.

Boosting neuregulin 1 type-III expression hastens SMA motor axon maturation.

Intercellular communication between axons and Schwann cells is critical for attaining the complex morphological steps necessary for axon maturation. In the early onset motor neuron disease spinal muscular atrophy (SMA), many motor axons are not ensheathed by Schwann cells nor grow sufficiently in radial diameter to become myelinated. These developmentally arrested motor axons are dysfunctional and vulnerable to rapid degeneration, limiting efficacy of current SMA therapeutics.

Analysis of Neurosurgery Influencers on Instagram: Trends and Patterns of the Neurosurgeon's Social Media Footprint.

Objective: Social media outlets such as Instagram have recently become a popular tool for medical professionals to disseminate medical information to a large public audience. In this study, we identify the top neurosurgery influencers on Instagram and analyze trends between content type, audience interaction, and user engagement.

Methods: A list of neurosurgeon Instagram profiles based on the number of followers, user engagement, and average interaction were compiled.

The relationship between tumour infiltrating lymphocytes, Epstein-Barr virus and infection in gastric cancer.

Objective: Epstein-Barr virus (EBV) and (HP) infections have been extensively recognised as gastric cancer (GC) triggers, and recent publications suggest they could behave as predictive markers for immune-modulating therapies. Tumour-infiltrating lymphocytes (TILs) have also been identified as a predictive biomarker for immunotherapy in different malignancies. This study aimed to investigate the association between EBV and HP infection with TIL levels in GC.

Non-Fatal Strangulation/Choking During Sex and Its Associations with Mental Health: Findings from an Undergraduate Probability Survey.

Choking/strangulation during sex is prevalent among young adults in the United States. We examined associations between having ever been choked and participants' current mental health symptoms (e.g.

Evolutionary Perspective and Expression Analysis of Intronless Genes Highlight the Conservation of Their Regulatory Role.

The structure of eukaryotic genes is generally a combination of exons interrupted by intragenic non-coding DNA regions (introns) removed by RNA splicing to generate the mature mRNA. A fraction of genes, however, comprise a single coding exon with introns in their untranslated regions or are intronless genes (IGs), lacking introns entirely. The latter code for essential proteins involved in development, growth, and cell proliferation and their expression has been proposed to be highly specialized for neuro-specific functions and linked to cancer, neuropathies, and developmental disorders.

Potential Prognostic Value of Preoperative Leukocyte Count, Lactate Dehydrogenase and C-Reactive Protein in Thymic Epithelial Tumors.

Thymic epithelial tumors are the most common mediastinal tumors. Surgery is the mainstay of treatment and complete resection provides the best survival rate. However, advanced tumors often require multimodality treatment and thus we analyzed the prognostic potential of routine circulating biomarkers that might help to risk-stratify patients beyond tumor stage and histology.

A de novo transcriptional atlas in Danaus plexippus reveals variability in dosage compensation across tissues.

A detailed knowledge of gene function in the monarch butterfly is still lacking. Here we generate a genome assembly from a Mexican nonmigratory population and used RNA-seq data from 14 biological samples for gene annotation and to construct an atlas portraying the breadth of gene expression during most of the monarch life cycle. Two thirds of the genes show expression changes, with long noncoding RNAs being particularly finely regulated during adulthood, and male-biased expression being four times more common than female-biased.

Positive Selection in Gene Regulatory Factors Suggests Adaptive Pleiotropic Changes During Human Evolution.

Gene regulatory factors (GRFs), such as transcription factors, co-factors and histone-modifying enzymes, play many important roles in modifying gene expression in biological processes. They have also been proposed to underlie speciation and adaptation. To investigate potential contributions of GRFs to primate evolution, we analyzed GRF genes in 27 publicly available primate genomes.

Torque Teno Virus load in lung cancer patients correlates with age but not with tumor stage.

Background: Torque teno virus (TTV) is a ubiquitous non-pathogenic virus, which is suppressed in immunological healthy individuals but replicates in immune compromised patients. Thus, TTV load is a suitable biomarker for monitoring the immunosuppression also in lung transplant recipients. Since little is known about the changes of TTV load in lung cancer patients, we analyzed TTV plasma DNA levels in lung cancer patients and its perioperative changes after lung cancer surgery.
