Background: Duchenne muscular dystrophy (DMD) is a severe neuromuscular disorder, often leading to wheelchair dependence by age 13 with limited treatment options, largely relying on glucocorticosteroids. We assessed the efficacy and safety of vamorolone, a modified synthetic corticosteroid, for DMD.

Methods: We performed a systematic review and meta-analysis using seven databases including prospective studies comparing vamorolone with glucocorticosteroids or placebo in DMD patients.

Background: Telemedicine provides specialized medical expertise in underserved areas where neurological expertise is frequently not available on a daily basis for hospitalized stroke patients. While tele-consultations are well established in acute stroke assessment, the value of telemedicine-based ward-rounds in the subsequent in-patient stroke management is unknown.

Methods: Four telemedicine stroke networks in Germany, implemented in eight out of 16 federal states, participate in this prospective observational multi-center study.

Background: Environmental enteric dysfunction (EED) is an acquired, subclinical state of intestinal inflammation common in children and adults in low-income and middle-income countries. Although vitamin D-3 supplementation has purported anti-inflammatory properties, its ability to ameliorate biomarkers of EED remains unclear.

Objectives: This study aimed to examine the effects of maternal vitamin D-3 supplementation during pregnancy and lactation on biomarkers of EED, systemic inflammation, and growth in women living with HIV and their infants in Dar es Salaam, Tanzania.

Background: Muscle pain is a common symptom in patients with neuromuscular disorders (NMD) and accounts for severely reduced quality of life. OBJECTIVE: This clinical study aimed to observe possible differences in pain prevalence among distinct NMDs and to determine whether the patients' nociceptive pain is influenced by gender, muscle strength and psychological factors and to examine potential pain-associated alterations in muscle properties.

Methods: The cross-sectional study on nociceptive pain in various NMDs involved patient-reported outcomes, muscle strength evaluations (dynamometry and quick motor function test (QMFT)), nociceptive pain evaluations (muscular pressure pain threshold (PPT)), and non-invasive measurement of muscle stiffness, frequency, decrement, relaxation, and creep (myotonometry).

Background: Infections with Herpes simplex virus (HSV)-1 or -2 usually present as mild chronic recurrent disease, however in rare cases can result in life-threatening conditions with a large spectrum of pathology. Monoclonal antibody therapy has great potential especially to treat infections with virus resistant to standard therapies. HDIT101, a humanized IgG targeting HSV-1/2 gB was previously investigated in phase 2 clinical trials.

Introduction And Purpose: Basilar artery occlusion (BAO) is still one of the most devastating neurological conditions associated with high morbidity and mortality. In the present study, we aimed to assess the role of posterior circulation collaterals as predictors of outcome in the BASICS trial and to compare two grading systems (BATMAN score and PC-CS) in terms of prognostic value.

Methods: We performed a sub-analysis of the BASICS trial.

Almonds (Prunus dulcisMill.) are consumed worldwide and their geographical origin plays a crucial role in determining their market value. In the present study, a total of 250 almond reference samples from six countries (Australia, Spain, Iran, Italy, Morocco, and the USA) were non-polar extracted and analyzed by UPLC-ESI-IM-qToF-MS.

Article Synopsis
  • Transmembrane protein 16F (TMEM16F) is a calcium-activated protein that works as both an ion channel and a phospholipid scramblase, showing diverse structural forms that impact its function.
  • Using atomic force microscopy, researchers observed various TMEM16F assemblies that have not been seen in previous high-resolution studies, revealing different dimerization and protomer orientations.
  • The study establishes a link between calcium-induced activation and structural changes in TMEM16F, suggesting that its conformational diversity plays a crucial role in its physiological activities, particularly in lipid and ion transport.

Objectives: In the surgical treatment of colorectal carcinoma (CRC), 1 in 10 patients has a peritumorous adhesion or tumor infiltration in the adjacent tissue or organs. Accordingly, multivisceral resection (MVR) must be performed in these patients. This prospective multicenter observational study aimed to analyze the possible differences between non-multivisceral resection (nMVR) and MVR in terms of early postoperative and long-term oncological treatment outcomes.

The analysis of proteins in the gas phase benefits from detectors that exhibit high efficiency and precise spatial resolution. Although modern secondary electron multipliers already address numerous analytical requirements, additional methods are desired for macromolecules at energies lower than currently used in post-acceleration detection. Previous studies have proven the sensitivity of superconducting detectors to high-energy particles in time-of-flight mass spectrometry.

Family influences on child quality of life (QoL) are increasingly understood. Parenting behavior and parent individual psychopathology are among the established predictors of offspring mental health. However, literature often addresses these factors as 'parental', lacking further gender-specific differentiation while predominantly studying maternal aspects.

Muscarinic acetylcholine receptor M3 (M3R) has repeatedly been shown to be prominently expressed in human colorectal cancer (CRC), playing roles in proliferation and cell invasion. Its therapeutic targetability has been suggested in vitro and in animal models. We aimed to investigate the clinical role of MR3 expression in CRC for human survival.

Lymphoceles (LC) occur in up to 60% after robot-assisted radical prostatectomy (RARP) and pelvic lymphadenectomy (PLND). In 2-10%, they are symptomatic and may cause complications and require treatment. Data on risk factors for the formation of lymphoceles after RARP and PNLD remain sparse in the urologic literature and are inconclusive to date.

The TNF-superfamily member TRAIL is known to mediate selective apoptosis in tumor cells suggesting this protein as a potential antitumor drug target. However, initial successful pr-clinical results could not be translated into the clinic. Reasons for the ineffectiveness of TRAIL-targeting in tumor therapies could include acquired TRAIL resistance.

Background And Purpose: We characterized autonomic pilomotor and sudomotor skin function in early Parkinson's disease (PD) longitudinally.

Methods: We enrolled PD patients (Hoehn and Yahr 1-2) and healthy controls from movement disorder centers in Germany, Hungary, and the United States. We evaluated axon-reflex responses in adrenergic sympathetic pilomotor nerves and in cholinergic sudomotor nerves and assessed sympathetic skin response (SSR), predominantly parasympathetic neurocardiac function via heart rate variability, and disease-related symptoms at baseline, after 2 weeks, and after 1 and 2 years.

Article Synopsis
  • Interleukin-6 is crucial for the advancement and poor outcomes of pancreatic ductal adenocarcinoma (PDAC), and the study investigates the effectiveness of targeting its signaling with inhibitors like SC144 and raloxifene in combination with paclitaxel.
  • In vitro results showed that the combination of paclitaxel and raloxifene significantly inhibited cell growth and increased apoptosis in pancreatic cancer cell lines, while the SC144 combination did not show similar results.
  • In an orthotopic mouse model of PDAC, both drug combinations reduced tumor weight and volume, and raloxifene's combination with paclitaxel led to lower survivin expression, indicating a potential pathway for improving chemotherapy outcomes and reducing side effects.

Purpose: Interleukin 6 (IL-6), Oncostatin M (OSM), and downstream effector STAT3 are pro-tumorigenic agents in pancreatic ductal adenocarcinoma (PDAC). Glycoprotein 130 (gp130) is a compound of the IL-6 and OSM receptor complex that triggers STAT3 signaling. SC144 is a small molecule gp130 inhibitor with anticancer activity.
