UNLABELLED: We aimed to evaluate the incidence of SARS-CoV-2 breakthrough infection of SARS-CoV-2 vaccines in people with MS (PwMS) on high-efficacy disease-modifying therapies (HET) included in the national MS registry in Argentina (RelevarEM).
METHODS: Non-interventional, retrospective cohort study that collected information directly from RelevarEM. Adult PwMS who had been treated for at least 6 months with a HET (ocrelizumab, natalizumab, alemtuzumab, cladribine) who had received at least two doses of SARS-CoV-2 vaccines available in Argentina were included. Full course of vaccination was considered after the second dose of the corresponding vaccines. Cumulative incidence of SARS-CoV-2 infection was reported for the whole cohort by Kaplan-Meier survival curves (which is expressed in percentage) as well as incidence density (which is expressed per 10.000 patients/day with 95% CI).
RESULTS: Two hundred twenty-eight PwMS were included. Most frequent first and second dose received was AstraZeneca vaccine, followed by Sputnik vaccine. Most frequent HETs used in included patients were cladribine in 79 (34.8%). We found an incidence density of breakthrough COVID-19 infection of 3.5 × 10.000 patients/day (95% CI 2.3-6.7) after vaccination in Argentina. We described the incidence rate after vaccination for every HET used, it being significantly higher for ocrelizumab compared with other HETs (p = 0.005). Only five patients presented a relapse during the follow-up period with no differences regarding the pre-vaccination period.
CONCLUSIONS: We found an incidence density of breakthrough COVID-19 infection of 3.5 × 10.000 patients/day (95% CI 2.3-6.7) after vaccination in Argentina.

Remodeling retinal Müller glial fate, including gliosis inhibition and pro-reprogramming, represents a crucial avenue for treating degenerative retinal diseases. Stem cell transplantation exerts effects on modulating retinal Müller glial fate. However, the optimized stem cell products and the underlying therapeutic mechanisms need to be investigated. In the present study, we found that retinal progenitor cells from human embryonic stem cell-derived retinal organoids (hERO-RPCs) transferred extracellular vesicles (EVs) into Müller cells following subretinal transplantation into RCS rats. Small EVs from hERO-RPCs (hERO-RPC-sEVs) were collected and were found to delay photoreceptor degeneration and protect retinal function in RCS rats. hERO-RPC-sEVs were taken up by Müller cells both in vivo and in vitro, and inhibited gliosis while promoting early dedifferentiation of Müller cells. We further explored the miRNA profiles of hERO-RPC-sEVs, which suggested a functional signature associated with neuroprotection and development, as well as the regulation of stem cell and glial fate. Mechanistically, hERO-RPC-sEVs might regulate the fate of Müller cells by miRNA-mediated nuclear factor I transcription factors B (NFIB) downregulation. Collectively, our findings offer novel mechanistic insights into stem cell therapy and promote the development of EV-centered therapeutic strategies.
ETHNOPHARMACOLOGICAL RELEVANCE: Amyotrophic lateral sclerosis (ALS) is a fetal neuromuscular disorder characterized by the gradual deterioration of motor neurons. Semen Strychni pulveratum (SSP), a processed version of Semen Strychni (SS) powder, is widely used to treat ALS in China. Vomicine is one of the most primary components of SS. However, their pharmacological effects and mechanisms for ALS remain elusive.
AIM OF THE STUDY: This study aimed to evaluate the neuroprotective and anti-neuroinflammatory effects of SSP and vomicine, as well as to explore their protective roles in ALS and the underlying mechanisms.
MATERIALS AND METHODS: In vivo, 8-week-old hSOD1-WT mice and hSOD1-G93A mice were orally administered different concentrations of SSP (SSP-L = 5.46 mg/ml, SSP-M = 10.92 mg/ml or SSP-H = 16.38 mg/ml) once every other day for 8 weeks. A series of experiments, including body weight measurement, footprint tests, Hematoxylin & Eosin staining, and Nissl staining, were performed to evaluate the preventive effect of SSP. Immunofluorescence staining, western blotting, and RT-qPCR were subsequently performed to evaluate activation of the cGAS-STING-TBK1 pathway in the spinal cord. In vitro, hSOD1G93A NSC-34 cells were treated with vomicine to further explore the pharmacological mechanism of vomicine in the treatment of ALS via the cGAS-STING-TBK1 pathway.
RESULTS: SSP improved motor function, body weight loss, gastrocnemius muscle atrophy, and motor neuron loss in the spine and cortex of hSOD1-G93A mice. Furthermore, the cGAS-STING-TBK1 pathway was activated in the spinal cord of hSOD1-G93A mice, with activation predominantly observed in neurons and microglia. However, the levels of cGAS, STING, and pTBK1 proteins and cGAS, IRF3, IL-6, and IL-1β mRNA were reversed following intervention with SSP. Vomicine not only downregulated the levels of cGAS, TBK1, IL-6 and IFN-β mRNA, but also the levels of cGAS and STING protein in hSOD1G93A NSC-34 cells.
CONCLUSION: This study demonstrated that SSP and vomicine exert neuroprotective and anti-neuroinflammatory effects in the treatment of ALS. SSP and vomicine may reduce neuroinflammation by regulating the cGAS-STING-TBK1 pathway, and could thereby play a role in ALS treatment.
BACKGROUND: Ascaris lumbricoides cystatin (Al-CPI) prevents the development of allergic airway inflammation and dextran-induced colitis in mice models. It has been suggested that helminth-derived cystatins inhibit cathepsins in dendritic cells (DC), but their immunomodulatory mechanisms are unclear. We aimed to analyze the transcriptional profile of human monocyte-derived DC (moDC) upon stimulation with Al-CPI to elucidate target genes and pathways of parasite immunomodulation.
METHODS: moDC were generated from peripheral blood monocytes from six healthy human donors of Denmark, stimulated with 1 µM of Al-CPI, and cultured for 5 hours at 37°C. RNA was sequenced using TrueSeq RNA libraries and the NextSeq 550 v2.5 (75 cycles) sequencing kit (Illumina, Inc). After QC, reads were aligned to the human GRCh38 genome using Spliced Transcripts Alignment to a Reference (STAR) software. Differential expression was calculated by DESEq2 and expressed in fold changes (FC). Cell surface markers and cytokine production by moDC were evaluated by flow cytometry.
RESULTS: Compared to unstimulated cells, Al-CPI stimulated moDC showed differential expression of 444 transcripts (|FC| ≥1.3). The top significant differences were in Kruppel-like factor 10 (KLF10, FC 3.3, PBH = 3 x 10-136), palladin (FC 2, PBH = 3 x 10-41), and the low-density lipoprotein receptor (LDLR, FC 2.6, PBH = 5 x 10-41). Upregulated genes were enriched in regulation of cholesterol biosynthesis by sterol regulatory element-binding proteins (SREBP) signaling pathways and immune pathways. Several genes in the cholesterol biosynthetic pathway showed significantly increased expression upon Al-CPI stimulation, even in the presence of lipopolysaccharide (LPS). Regarding the pathway of negative regulation of immune response, we found a significant decrease in the cell surface expression of CD86, HLA-DR, and PD-L1 upon stimulation with 1 µM Al-CPI.
CONCLUSION: Al-CPI modifies the transcriptome of moDC, increasing several transcripts encoding enzymes involved in cholesterol biosynthesis and SREBP signaling. Moreover, Al-CPI target several transcripts in the TNF-alpha signaling pathway influencing cytokine release by moDC. In addition, mRNA levels of genes encoding KLF10 and other members of the TGF beta and the IL-10 families were also modified by Al-CPI stimulation. The regulation of the mevalonate pathway and cholesterol biosynthesis suggests new mechanisms involved in DC responses to helminth immunomodulatory molecules.
OBJECTIVE: To investigate the structural abnormalities, genetic results, and postnatal clinical outcomes of fetuses with bovine aortic arch (Bovine Aortic Arch, BAA) to provide a basis for prenatal counseling and management.
METHODS: A retrospective analysis was conducted on 216 fetuses diagnosed with bovine aortic arch through prenatal ultrasound screening at the First Affiliated Hospital of Anhui Medical University and the No.901 Hospital of the Joint Service of the People's Liberation Army from January 2019 to February 2023. Their family history of genetic diseases, prenatal screening results, and postnatal follow-up data were collected. The fetuses were divided into an isolated BAA group (n = 192) and a non-isolated BAA group (n = 24). Chromosomal karyotyping and copy number variation (CNV) testing were conducted, and statistical analysis was performed using SPSS 22.0 software.
RESULTS: Of the 216 fetuses with BAA, 192 were isolated BAA (88.89%), and 24 were non-isolated BAA (11.11%). Among the isolated BAA fetuses, only 1 case (0.52%) had chromosomal karyotype and pathogenic CNV abnormalities. Among the non-isolated BAA fetuses, 4 cases (16.67%) had chromosomal or CNV abnormalities, but the overall risk was low. The postnatal outcomes of isolated BAA fetuses were good (99.48%), while 79.17% of non-isolated BAA fetuses had good postnatal outcomes.
CONCLUSION: Most BAA fetuses are isolated, with a very low incidence of chromosomal abnormalities and pathogenic CNVs, and have good postnatal outcomes. The clinical value of isolated BAA is limited, and invasive prenatal diagnosis is not recommended for low-risk populations. Prenatal screening should focus on the risk of concurrent severe structural anomalies and chromosomal abnormalities.

Chronic Obstructive Pulmonary Disease (COPD) significantly impacts patients' quality of life and burdens healthcare systems. Magnesium is crucial for lung function and reducing respiratory disease risk. This study investigates the association between Magnesium Depletion Score (MDS) and COPD and explores whether inflammatory markers mediate this relationship. A cross-sectional analysis was conducted using data from 30,490 participants in the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2018. MDS was calculated based on diuretic use, proton pump inhibitors, renal function, and alcohol consumption. Univariable and multivariable logistic regression analyses were performed to assess the association between MDS and COPD, adjusting for potential confounders. Mediation analysis was used to examine the roles of neutrophils, serum albumin, and the Systemic Immune-Inflammation Index (SII). In the univariable logistic model, higher MDS was significantly associated with increased COPD risk. Specifically, compared to MDS = 0, the odds ratios (OR) for COPD were 2.50, 4.12, 6.13, 8.53, and 7.81 for MDS = 1, 2, 3, 4, and 5, respectively (all P < 0.001). In the multivariable model, the ORs were 1.79, 2.25, 2.71, and 3.44 for MDS = 1, 2, 3, and 4, respectively (all P < 0.001). Higher neutrophil levels and SII were positively associated with increased COPD risk, while higher serum albumin levels were inversely associated. Mediation analysis indicated that neutrophils, serum albumin, and SII significantly mediated the MDS-COPD relationship. Higher MDS is significantly associated with increased COPD risk, mediated by systemic inflammation markers. Improving magnesium levels could potentially reduce COPD risk, warranting further research on magnesium supplementation in COPD prevention and management.
PURPOSE: To develop a quantitative tool for assessing the posterior ocular shape using widefield, volumetric optical coherence tomography (OCT) in eyes with myopia.
METHODS: This observational, cross-sectional study included 178 eyes from 113 participants. Participants underwent a standardized eye examination, including ocular biometry and a custom ultrawide OCT. True ocular shape was reconstructed by tracing the beam propagation from the system to the posterior eye. Gaussian curvature quantified the localized ocular shape, which was further categorized into five distinct categories. An ocular shape irregularity (OSI) was calculated using principal component analysis. Linear regression with breakpoints analyzed the relationship between ocular shape parameters and axial length (AL).
RESULTS: Increased curvature mean and variance were associated with more severe myopia (P < 0.001). Curvature categories (convex, normal, concave, and highly concave) differed significantly between the groups (all P < 0.001). Their correlations with AL revealed significant breakpoints between 27.1 and 27.2 mm. OSI, as a single metric for quantifying ocular shape distortion, was associated with more severe myopia (P < 0.001), and its correlation with AL revealed a breakpoint at 27.2 mm with a fourfold increase in slope steepness beyond this pivot. Determination of OSI was highly reproducible and could also be obtained with fewer scans.
CONCLUSIONS: Eyes exceeding 27.2 mm in length exhibit pronounced shape changes. Our framework can be seamlessly integrated into commercial OCTs for ocular shape deformation detection, which could aid in identifying eyes with pathologic myopia.
The investigators will recruit 70 patients with aortic stenosis (25 patients with asymptomatic moderate aortic stenosis and 25 patients with symptomatic severe aortic stenosis, 10 patients with mild aortic stenosis and 10 patients with aortic sclerosis) and 10 healthy volunteers, who will undergo baseline 68Ga-FAPI or 18F-AlF-FAPI PET/MR imaging to establish fibrosis activity in healthy myocardium and in context of chronic myocardial injury. All patients will have a follow up FAPI PET/ MR scan 1 year after their baseline scan to assess whether myocardial fibrosis activity reverses following aortic valve replacement and restoration of normal afterload in patients with severe aortic stenosis and if baseline myocardial fibrosis activity can predict progression in the fibrosis burden and clinical progression in patients with mild or moderate aortic stenosis or aortic sclerosis. Healthy volunteers will not undergo any repeat imaging.
The intervention sites will receive the results of the patient-reported depression severity collected during the phone interviews on a monthly basis. The patients in the intervention arm will be interviewed by phone once per month for 6 months.
This study aims at the possible effect of subliminal intragastric administration of fatty acids on responses to positive emotion induction, based on our earlier findings that subjective administration of fatty acid decreases neural responses to negative mood induction (Van Oudenhove et al, J Clin Invest 2011). After screening for exclusion criteria and the participants sign the informed consent form, an intravenous catheter is placed in the forearm, and a naso-gastric tube inserted through the nose. Then the test subject is connected to the equipment in order to record the activity of the autonomic nervous system, via three electrocardiogram electrodes. By using the nasogastric tube we serve a fatty acid solution (Dodecanoic acid, "fatty acid" condition) or a physiological saline solution ( "control" condition) intragastrically. The intragastric administration of low doses of this food ingredient has already been used in several previous studies by our research group and has proven perfectly safe. A positive or neutral emotional state will be induced by the combination of looking at emotional facial expressions and listening to classical music pieces that were previously validated for this purpose; This combination of incentives has already been used in previous studies of our research group. Responses will be measured by means of validated self-report scales and measurements of the vagal tone. We also take blood samples on a regular basis by the intravenous catheter for determination of gastrointestinal hormones, given our hypothesis that this may explain the effect on emotions. After removal of the nasogastric tube, the influence of subliminal administration of fatty acids and emotional state on food intake measured by means of a validated and previously drink test used in which participants "ad libitum" to drink a chocolate milkshake while the emotion-induction by means of classical music pieces continue. Finally, the intravenous catheter is removed.
When you take levonorgestrel and ethinyl estradiol tablets, which has a 91-day treatment cycle, you should expect to have 4 menstrual periods per year (bleeding when you are taking the 7 white pills). However, you also should expect to have more bleeding or spotting between your menstrual periods than if you were taking an oral contraceptive with a 28-day treatment cycle. During the first levonorgestrel and ethinyl estradiol tablets treatment cycle, about 1 in 3 women may have 20 or more days of unplanned bleeding or spotting (bleeding when you are taking pink pills). This bleeding or spotting tends to decrease during later cycles. Do not stop levonorgestrel and ethinyl estradiol tablets because of the bleeding. If the spotting continues for more than 7 consecutive days or if the bleeding is heavy, call your healthcare provider.
Participants were administered trigger point dry kneedling technique 6 times for 1 month, once every 5 days. The subject was positioned prone and the arm position was slightly changed related with the muscle. After the skin inspection it was cleaned with the alcohol. .
Facing increasing economization in the health care sector, clinicians have to adapt not only to the ever-growing economic challenges, but also to a patient-oriented health care. Treatment costs are the most important variable for optimizing success when facing scarce human resources, increasing material- and infrastructure costs in general, as well as low revenue flexibility due to flat rates per case in Germany, the so-called Diagnosis-Related Groups (DRG). University hospitals treat many patients with particularly serious illnesses. Therefore, their share of complex and expensive treatments, such as liver cirrhosis, is significantly higher. The resulting costs are not adequately reflected in the DRG flat rate per case, which is based on an average calculation across all hospitals, which increases this economic pressure. Thus, the aim of this manuscript is to review cost and revenue structures of the management of varices in patients with cirrhosis at a university center with a focus on hepatology. For this monocentric study, the data of 851 patients, treated at the Gastroenterology Department of a University Hospital between 2016 and 2020, were evaluated retrospectively and anonymously. Medical services (e.g., endoscopy, radiology, laboratory diagnostics) were analyzed within the framework of activity-based-costing. As part of the cost unit accounting, the individual steps of the treatment pathways of the 851 patients were monetarily evaluated with corresponding applicable service catalogs and compared with the revenue shares of the cost center and cost element matrix of the German (G-) DRG system. This study examines whether university-based high-performance medicine is efficient and cost-covering within the framework of the G-DRG system. We demonstrate a dramatic underfunding of the management of varicose veins in cirrhosis in our university center. It is therefore generally questionable whether and to what extent an adequate care for this patient collective is reflected in the G-DRG system.
Infertility can lead to the realization of follicular puncture or oocytes in order to obtain an embryo for medically assisted procreation. It is a long treatment for the couples concerned and this intervention, relatively simple in young patients, is associated with a very high level of anxiety. According to studies, the incidence of preoperative anxiety ranges from 11% to 80% in adult patients. In patients undergoing outpatient surgery, anxiolytics are not administered before anesthesia in outpatient surgery, as this would risk altering their "fitness for the street" and preventing their return home. Studies have shown a benefit of acupressing in the treatment of preoperative anxiety. This technique could therefore be an alternative to drug anxiety before surgery. Acupressing could also help these patients.
