[Treatment of cancer-related pain-From pharmacotherapy to invasive procedures].

Depending on the stage of the tumor up to 80% of the patients suffer from cancer-related pain but treatment is often inadequate. Multiple causes can trigger pain and these can be due to the tumor itself, its secondary consequences but also treatment related. A differentiated assessment and individually tailored treatment of cancer-related pain not only improve the quality of life but also reduce the risk of pain chronification.

Inhibition of Bone Morphogenetic Protein Signaling Prevents Tau Pathology in iPSC Derived Neurons and PS19 Mice.

Objective: Many neurodegenerative disorders share a common pathologic feature involving the deposition of abnormal tau protein in the brain (tauopathies). This suggests that there may be some shared pathophysiologic mechanism(s). The largest risk factor for the majority of these disorders is aging, suggesting involvement of the aging process in the shared pathophysiology.

Ultrasound visualization and blood flow velocity measurements of the adrenal arteries in the fetus.

Introduction: Detection and surveillance of fetal growth restriction (FGR) is well established, but there is still room for improvement. Animal studies indicate that compromised fetuses increase adrenal blood flow. Modern ultrasound equipment allows us to measure vascular impedance in the fetal adrenal arteries despite their modest size.

Zinc Influences the Efficacy of Betulinic Acid Treatment and Radiotherapy in Breast Cancer Cells.

The trace element zinc influences a number of biological reactions, including cell growth, apoptosis, and DNA damage, which affect tumor therapy. The natural compound betulinic acid (BA) and its derivatives are known for their antiviral, antibacterial, and antitumor effects. Previous studies show that BA and 3-acetyl-28-sulfamoyloxybetulin (CAI3) have high cytotoxicity and induce radiosensitization in breast cancer cells.

Intravenous Immunomodulatory Nanoparticles Prevent Secondary Damage after Traumatic Brain Injury.

After traumatic brain injury (TBI), monocyte/macrophage infiltration is a key early step in the development of an inflammatory cascade that leads to substantial secondary damage. Intravenous (IV) immunomodulatory nanoparticle (IMP) administration after TBI limits inflammatory cell infiltration and reduces both behavioral decline and lesion size without any noticeable toxicity. Here we show that there is a dose-response relationship between the amount of IMP administered and tissue damage which plateaus at a well-tolerated dose.

Bioinspired intratumoral infusion port catheter improves local drug delivery in the liver.

Tumor immune modulation can be achieved using intratumoral injection of different immunomodulators during different phases of the cancer-immunity cycle. Intratumoral infusion catheters have been used in brain tumors, but these are not suitable outside the brain, where breathing motion results in catheter migration. Here, we use microstereolithography to manufacture a barbed sidehole catheter, modeled after the barbs in a bee stinger, where the barbs maintain the catheter position in the tumor, and sideholes within the barbs infuse drug into tumor tissue.

The Diagnosis and Treatment of Neuropathic Pain.

Background: The reported prevalence of neuropathic pain in the general population in Germany is from 6.9% to 10%. There are both medical and surgical treatment options.

Impact of rapid blood culture identification PCR panel on optimal antibiotic use in methicillin-susceptible bacteremia.

Unlabelled: Rapid identification of methicillin-susceptible (MSSA) bacteremia may optimize antibiotic use and clinical outcomes. The study objective was to assess the impact of the BioFire® blood culture identification (BCID) polymerase chain reaction (PCR) panel on antibiotic use and clinical outcomes in patients with MSSA bacteremia. This was a retrospective chart review of adult inpatients with MSSA bacteremia during the pre-PCR (June 2018-December 2019) and post-PCR (June 2020-December 2021) implementation periods.

Validation Study of the Parkinson's Disease Stigma Questionnaire (PDStigmaQuest).

Background: Stigma is a relevant aspect of Parkinson's disease (PD). Specific stigma tools are needed to address the complex construct of stigma in PD comprehensively.

Objective: To test the dimensionality and psychometric properties of the newly developed Parkinson's Disease Stigma Questionnaire (PDStigmaQuest).

Detection of Guanine Quadruplexes by Raman Optical Activity and Quantum-Chemical Interpretation of the Spectra.

Quadruplexes formed by guanine derivatives or guanine-rich nucleic acids are involved in metabolism and genetic storage of many living organisms, they are used in DNA nanotechnologies or as biosensors. Since many quadruplex geometries are possible the determination of their structures in aqueous solutions is difficult. Raman optical activity (ROA) can make it easier: For guanosine monophosphate (GMP), we observed a distinct change of the spectra upon its condensation and quadruplex formation.

Liver Resection for Gastroenteropancreatic Neuroendocrine Tumors with Extrahepatic Disease.

: Although survival outcomes for neuroendocrine liver metastases (NETLM) are improved with liver-direct therapies (LDT), including hepatic debulking and nonsurgical trans-arterial embolization, the benefit is less established in the setting of concurrent extrahepatic disease (EHD). We performed a population-based study to characterize the rates of LDT being performed for NETLM with EHD patients and whether LDT is associated with survival outcomes. : Patients with NETLM and EHD were identified using the California Cancer Registry database merged with data from the California Office of Statewide Health Planning and Development between 2000 and 2012.

The Prevalence of Persistent Toe Walking in Children With and Without Autism Spectrum Disorder and the Odds of Subsequent Surgery.

Persistent toe walking is associated with autism spectrum disorder. The true prevalence of persistent toe walking and odds of progression to surgery in children with and without autism remains unclear. This retrospective descriptive study identified patients ages 3 to 17 years who were enrolled in our healthcare system over a 2-year period.

Validation of Quality Assessment Measures for Inpatient Gastroenterology Consults on Oncologic Patients in Non-teaching Services at a Cancer Center: A Cross-Sectional Study.

Objective: To develop and validate tools for measuring inpatient gastroenterology (GI) consultation quality on oncologic patients.

Methods: A total of 145 inpatient GI consults were analyzed using electronic health records in this cross-sectional study. Essential Consult Elements on oncologic-hospitalized patients (EE-COH) and Hospitalized Oncologic Patients Enhanced Quality of Consult Assessment Tool (HOPE-QCAT) were used for grading.

Experiences of patients with endometriosis with a digital health application: a qualitative analysis.

Background: Endometriosis is a frequent disease in women of reproductive age in which the endometrium occurs outside the uterine cavity. Multimodal treatment approaches are necessary due to loss of quality of life and the chronic nature of the disease. Digital health applications (DiGa) are becoming increasingly important.

Associations between fetal position at delivery and duration of active phase of labor: A historical cohort study.

Introduction: In clinical experience, occiput posterior (OP) position is associated with longer labor duration than occiput anterior (OA) position, but few studies have investigated the association between labor duration and fetal position. We aimed to compare duration of the active phase of labor in OP deliveries with OA deliveries in a contemporary population using survival methods. Secondary aims were to compare the frequencies of operative interventions, obstetric anal sphincter injuries (OASIS), postpartum hemorrhage, and newborn outcomes in OP with OA deliveries.

Increasing region of interest width reduces neonatal circumferential strain.

Objective: There is growing interest in speckle tracking echocardiography-derived strain as a measure of left ventricular function in neonates. However, knowledge gaps remain regarding the effect of image acquisition and processing parameters on circumferential strain measurements. The aim of this study was to evaluate the effect of using different region of interest (ROI) widths on speckle tracking derived circumferential strain in healthy neonates.

Phosphorylation site of L-alanyl-L-glutamine identified by Raman optical activity spectroscopy.

Phosphorylated peptides are instrumental in studying protein phosphorylation events. In the present study, Raman optical activity (ROA) is employed to elucidate the structure of a dipeptide, L-alanyl-L-glutamine (L-Ala-L-Gln) and its two differently alkylated N-phosphorylated derivatives. Theoretical simulations were conducted to aid the interpretation of peptide conformation variations upon phosphorylation, and of the measured Raman and ROA spectra.

YAP and TAZ differentially regulate postnatal cortical progenitor proliferation and astrocyte differentiation.

WW domain-containing transcription regulator 1 (WWTR1, referred to here as TAZ) and Yes-associated protein (YAP, also known as YAP1) are transcriptional co-activators traditionally studied together as a part of the Hippo pathway, and are best known for their roles in stem cell proliferation and differentiation. Despite their similarities, TAZ and YAP can exert divergent cellular effects by differentially interacting with other signaling pathways that regulate stem cell maintenance or differentiation. In this study, we show in mouse neural stem and progenitor cells (NPCs) that TAZ regulates astrocytic differentiation and maturation, and that TAZ mediates some, but not all, of the effects of bone morphogenetic protein (BMP) signaling on astrocytic development.
