Collagen-V and K-α-1 Tubulin Antibodies as Potential Markers of Unsuspected GERD-Related Lung Damage: Insights from a Cross-Sectional Analysis.

Purpose: Our group has proposed that aspiration of gastric contents leads to exposure of normally sequestered lung self-antigens (SAgs), specifically collagen-V (Col-V) and K-α-1-tubulin (Kα1T), which elicits an immune response characterized by increasing concentrations of self-antibodies (SAbs) anti-Col-V and anti-Kα1T. We sought to establish the point prevalence of abnormally elevated concentrations of SAbs among patients with pathological gastroesophageal reflux disease (GERD) and/or hiatal hernia undergoing antireflux surgery (ARS).

Methods: For this cross-sectional study, we retrieved a plasma aliquot from the Norton Thoracic Institute BioBank from blood samples that were taken preoperatively from patients who underwent ARS between November 2019 and August 2022.

Primary central nervous system post-transplantation lymphoproliferative disorder: A case report and systematic review of imaging findings.

Primary central nervous system post-transplant lymphoproliferative disease (PCNS-PTLD) is a rare subset of post-transplant lymphoproliferative disorder (PTLD) isolated to the CNS without nodal or extra-nodal organ involvement [1,2]. PCNS-PTLD occurs primarily in patients following either solid organ transplants or hematopoietic stem cell transplants and tends to be monomorphic DLBCL. The development of PCNS-PTLD is commonly associated with EBV infection [3].

Effects of hydrogen gas inhalation on L-DOPA-induced dyskinesia.

L-3,4-dihydroxyphenylalanine (L-DOPA)-induced dyskinesia is a side effect of Parkinson's disease treatment and it is characterized by atypical involuntary movements. A link between neuroinflammation and L-DOPA-induced dyskinesia has been documented. Hydrogen gas (H) has neuroprotective effects in Parkinson's disease models and has a major anti-inflammatory effect.

Unilateral inguinofemoral lymphadenectomy in patients with early-stage vulvar squamous cell carcinoma and a unilateral metastatic sentinel lymph node is safe.

Objective: Optimal management of the contralateral groin in patients with early-stage vulvar squamous cell carcinoma (VSCC) and a metastatic unilateral inguinal sentinel lymph node (SN) is unclear. We analyzed patients who participated in GROINSS-V I or II to determine whether treatment of the contralateral groin can safely be omitted in patients with a unilateral metastatic SN.

Methods: We selected the patients with a unilateral metastatic SN from the GROINSS-V I and II databases.

Radiotherapy Versus Inguinofemoral Lymphadenectomy as Treatment for Vulvar Cancer Patients With Micrometastases in the Sentinel Node: Results of GROINSS-V II.

Purpose: The Groningen International Study on Sentinel nodes in Vulvar cancer (GROINSS-V)-II investigated whether inguinofemoral radiotherapy is a safe alternative to inguinofemoral lymphadenectomy (IFL) in vulvar cancer patients with a metastatic sentinel node (SN).

Methods: GROINSS-V-II was a prospective multicenter phase-II single-arm treatment trial, including patients with early-stage vulvar cancer (diameter < 4 cm) without signs of lymph node involvement at imaging, who had primary surgical treatment (local excision with SN biopsy). Where the SN was involved (metastasis of any size), inguinofemoral radiotherapy was given (50 Gy).

CALLA: Efficacy and safety of concurrent and adjuvant durvalumab with chemoradiotherapy versus chemoradiotherapy alone in women with locally advanced cervical cancer: a phase III, randomized, double-blind, multicenter study.

Unlabelled: BackgroundConcurrent chemoradiotherapy is the standard of care for locally advanced cervical cancer. Concurrent chemoradiotherapy with programmed blockade of the cell death-1/programmed cell death-ligand 1 pathway may promote a more immunogenic environment through increased phagocytosis, cell death, and antigen presentation, leading to enhanced immune-mediated tumor surveillance.

Primary Objective: The CALLA trial is designed to determine the efficacy and safety of the programmed cell death-ligand 1 blocking antibody, durvalumab, with and following concurrent chemoradiotherapy versus concurrent chemoradiotherapy alone in women with locally advanced cervical cancer.

Methods: Summarize toxicity, grade, and health-related quality of life within 1 month of treatment discontinuation for women receiving chemotherapy with bevacizumab in GOG240.

Results: Of the 227 patients who received chemotherapy with bevacizumab, 148 discontinued study protocol treatment (90 for disease progression and 58 for toxicity).

Use of Intraventricular Medications in Critically Ill Patients: A Systematic Review.

New evidence and increased use of intracranial devices have increased the frequency of intraventricular (IVT) medication administration in the neurologic intensive care unit. Significant benefits and risks are associated with administration of medications directly into the central nervous system. This review summarizes important literature, along with key information for clinicians regarding the administration, dosing, monitoring, and adverse effects related to IVT medication usage.

Patient-specific parameter estimates of glioblastoma multiforme growth dynamics from a model with explicit birth and death rates.

Glioblastoma multiforme (GBM) is an aggressive primary brain cancer with a grim prog-nosis. Its morphology is heterogeneous, but prototypically consists of an inner, largely necrotic core surrounded by an outer, contrast-enhancing rim, and often extensive tumor-associated edema beyond. This structure is usually demonstrated by magnetic resonance imaging (MRI).

Less is more: Parahippocampal resection or endoscopic assistance in ambient cistern surgery? Qualitative and quantitative assessment of subtemporal approach.

The ambient cistern is an arachnoid complex that extends from the crural cistern to lateral border of cerebral colliculi. The subtemporal approach has been recognized as the best access to reach pathologies in the ambient cistern, however many disadvantages exist. The present work aims to analyze quantitatively the area of exposure provided by the subtemporal access.

Fiber Connections of the Supplementary Motor Area Revisited: Methodology of Fiber Dissection, DTI, and Three Dimensional Documentation.

The purpose of this study is to show the methodology for the examination of the white matter connections of the supplementary motor area (SMA) complex (pre-SMA and SMA proper) using a combination of fiber dissection techniques on cadaveric specimens and magnetic resonance (MR) tractography. The protocol will also describe the procedure for a white matter dissection of a human brain, diffusion tensor tractography imaging, and three-dimensional documentation. The fiber dissections on human brains and the 3D documentation were performed at the University of Minnesota, Microsurgery and Neuroanatomy Laboratory, Department of Neurosurgery.

The role of AKT isoforms in glioblastoma: AKT3 delays tumor progression.

The growth factor receptor/PI3K/AKT pathway is an important drug target in many cancers including Glioblastoma. AKT, a key node in the pathway, has 3 isoforms, AKT1, AKT2 and AKT3. Here we investigate their role in GBM.

Immunoprecipitation and mass spectrometry defines an extensive RBM45 protein-protein interaction network.

The pathological accumulation of RNA-binding proteins (RBPs) within inclusion bodies is a hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). RBP aggregation results in both toxic gain and loss of normal function. Determining the protein binding partners and normal functions of disease-associated RBPs is necessary to fully understand molecular mechanisms of RBPs in disease.

Management of rhinosinusitis during pregnancy: systematic review and expert panel recommendations.

Background: Management of rhinosinusitis during pregnancy requires special considerations.

Objectives: 1. Conduct a systematic literature review for acute and chronic rhinosinusitis (CRS) management during pregnancy.

Effect of HIV co-infection on adherence to a 12-week regimen of hepatitis C virus therapy with ledipasvir and sofosbuvir.

Objective: As the treatment of hepatitis C virus (HCV) infection has evolved to directly acting antiviral agents, the impact of these directly acting antiviral-only regimens on improving adherence to HCV treatment in HIV/HCV coinfected populations has not been evaluated. The study compared adherence to ledipasvir/sofosbuvir (LDV/SOF) in HCV monoinfected and HIV/HCV coinfected individuals.

Design: Adherence was measured from participants in two phase 2 open-label studies (NCT01805882 and NCT01878799).

High adherence to all-oral directly acting antiviral HCV therapy among an inner-city patient population in a phase 2a study.

Background: As treatment for chronic hepatitis C (HCV) virus has evolved to all-oral, interferon-free directly acting antiviral (DAA) therapy, the impact of these improvements on patient adherence has not been described.

Methods: Medication adherence was measured in 60 HCV, genotype-1, treatment-naïve participants enrolled in a phase 2a clinical trial at the National Institutes of Health and community clinics. Participants received either ledipasvir/sofosbuvir (LDV/SOF) (90 mg/400 mg) (one pill) daily for 12 weeks, LDV/SOF + GS-9451 (80 mg/day) (two pills) daily for 6 weeks, or LDV/SOF + GS-9669 (500 mg twice daily; three pills, two in the morning, one in the evening) for 6 weeks.

Moderate Sustained Virologic Response Rates With 6-Week Combination Directly Acting Anti-Hepatitis C Virus Therapy in Patients With Advanced Liver Disease.

Background: Treatment of genotype 1 hepatitis C virus (HCV) infection with combination directly acting antivirals (DAA) for 8-24 weeks is associated with high rates of sustained virologic response (SVR). We previously demonstrated that adding a third DAA to ledipasvir and sofosbuvir (LDV/SOF) can result in high SVR rates in patients without cirrhosis. In this study, we investigated whether a similar regimen would yield equivalent rates of cure in patients with advanced liver fibrosis.

The Role of Endoscopic Assistance in Ambient Cistern Surgery: Analysis of Four Surgical Approaches.

Objective: We used microscopy with endoscopic assistance to conduct an objective analysis of 4 surgical approaches commonly used in the surgery of the ambient cistern: infratentorial supracerebellar (SC), occipital interhemispheric (OI), subtemporal (ST), and transchoroideal (TC). In addition, we performed a parahippocampalis gyrus resection in the ST context.

Methods: Each approach (SC, OI, ST, TC) was performed on 3 cadaveric heads (6 sides).

Impact of multiple sclerosis relapse: The NARCOMS participant perspective.

Acute relapses continue to be a significant aspect of multiple sclerosis (MS) on both the epidemiologic level and the individual patient level. Past work demonstrates residual disability from relapses as well as high patient-reported rates of ineffective relapse treatment. To better characterize the impact of MS relapses on the patient, a relapse-specific survey was administered through the North American Research Committee on Multiple Sclerosis (NARCOMS) Registry to 1000 registry participants who had reported at least one relapse in the past 12 months.

Method for obtaining primary ovarian cancer cells from solid specimens.

Reliable tools for investigating ovarian cancer initiation and progression are urgently needed. While the use of ovarian cancer cell lines remains a valuable tool for understanding ovarian cancer, their use has many limitations. These include the lack of heterogeneity and the plethora of genetic alterations associated with extended in vitro passaging.

[Robotic surgery in gynecology].

Introduction of robotic surgery in the first decade of the 21 century was one of the biggest breakthroughs in surgery since the introduction of anesthesia. For the first time in history the surgeon was placed remotely from the patient and was able to operate with the device that has more degrees of freedom than human hand. Initially developed for the US Military in order to allow surgeons to be removed from the battlefield, surgical robots quickly made a leap to the mainstream medicine.
