BACKGROUND: Spasticity is a common feature in patients with disruptions in corticospinal pathways. However, the term is used ambiguously. Here, spasticity is defined as enhanced velocity-dependent stretch reflexes and placed within the context of deforming spastic paresis encompassing other forms of muscle overactivity. OBJECTIVE: This scoping review aims at evaluating the clinimetric quality of clinical outcome assessments (COAs) for spasticity across different pathologies and to make recommendations for their use. METHODS: A literature search was conducted to identify COAs used to assess spasticity. An international expert panel evaluated the measurement properties in the included COAs. Recommendations were based on the MDS-COA program methodology based on three criteria: if the COA was (1) applied to patients with spastic paresis, (2) used by others beyond the developers, and (3) determined to be reliable, valid, and sensitive to change in patients with spasticity. RESULTS: We identified 72 COAs of which 17 clinician-reported outcomes (ClinROs) and 6 patient-reported outcomes (PROs) were reviewed. The Tardieu Scale was the only ClinRO recommended for assessing spasticity. One ClinRO-Composite Spasticity Index-and two PROs-Spasticity 0-10 Numeric Rating Scale and 88-Item Multiple Sclerosis Spasticity Scale-were recommended with caveats. The Ashworth-derived COAs were excluded after evaluation due to their focus on muscle tone rather than spasticity, as defined in this review. CONCLUSIONS: The Tardieu Scale is recommended for assessing spasticity, and two PROs are recommended with caveats. Consistent terminology about the various types of muscle overactivity is necessary to facilitate their assessment and treatment. © 2024 The Author(s).

The aim of this prospective study was to assess the duration of culture-viable SARS-CoV-2 and to monitor the emergence of mutations in a cohort of 23 kidney transplant recipients (KTRs) from June 2022 to June 2023. Combined nares/oropharyngeal swabs were collected weekly starting as soon as possible after symptom onset. The time from symptom onset to a negative culture was 11 days (interquartile range, 8-14), while the time to negative reverse transcriptase quantitative polymerase chain reaction was 18 days (interquartile range, 15-30). Beyond the first swab, 21.7% had a positive culture, and 8.7% replicated viable virus for longer than 30 days. T cell depletion (rate ratio, 2.5; 95% confidence interval [95% CI], 1.9-3.3; P < .001) and time from transplantation (rate ratio, 0.93; 95% CI, 0.90-0.97; P = .006) were associated with the time of viable virus shedding. A cycle threshold value of 24.2 demonstrated a 91.3% negative predictive value of viability (95% credible interval [95% CrI], 76-100). The odds of viability decreased by 69% per week of infection (odds ratio, 0.31; 95% CrI, 0.12-0.76). Overall, ribonucleic acid sequencing did not show accelerated molecular evolution though mutation rate could be increased in molnupiravir-treated KTRs. In conclusion, viable SARS-CoV-2 is eliminated rapidly, the risk of virus evolution is low, and prolonged self-isolation is generally unnecessary for most KTRs.

BACKGROUND: Isolated injury to the superior mesenteric vein (SMV) caused by blunt abdominal trauma is rare but often lethal, especially in pediatric patients. Due to the low incidence of SMV injuries, there are no universal guidelines for its diagnosis and treatment. The diagnosis is made using either computed tomography (CT) or intraoperative exploration. Primary vascular repair is recommended. CASE REPORT: A 10-year-old girl was transferred to a trauma center after a high-energy motor vehicle collision. Under the diagnosis of acute abdomen with hemoperitoneum, the patient underwent urgent laparotomy, 34 min after admission to the hospital. A complete laceration of the SMV trunk was observed. Definitive vascular repair of the transected SMV was performed. An interposition graft from the internal jugular vein was used with a good postoperative course. CONCLUSION: This case report demonstrates that definitive vascular repair of the SMV reduces the risk of intestinal ischemia and should be performed in cases where ligation presents a real threat to small bowel viability. In cases of severe SMV injury, the internal jugular vein is a high-quality and easily accessible graft.

The glycoprotein clusterin (CLU) is involved in cell proliferation and DNA damage repair and is highly expressed in tumor cells. Here, we aimed to investigate the effects of CLU dysregulation on two human astrocytic cell lines: CCF-STTG1 astrocytoma cells and SV-40 immortalized normal human astrocytes. We observed that suppression of CLU expression by RNA interference inhibited cell proliferation, triggered the DNA damage response, and resulted in cellular senescence in both cell types tested. To further investigate the underlying mechanism behind these changes, we measured reactive oxygen species, assessed mitochondrial function, and determined selected markers of the senescence-associated secretory phenotype. Our results suggest that CLU deficiency triggers oxidative stress-mediated cellular senescence associated with pronounced alterations in mitochondrial membrane potential, mitochondrial mass, and expression levels of OXPHOS complex I, II, III and IV, indicating mitochondrial dysfunction. This report shows the important role of CLU in cell cycle maintenance in astrocytes. Based on these data, targeting CLU may serve as a potential therapeutic approach valuable for treating gliomas.

Cancer immunotherapy is increasingly used in clinical practice, but its success rate is reduced by tumor escape from the immune system. This may be due to the genetic instability of tumor cells, which allows them to adapt to the immune response and leads to intratumoral immune heterogeneity. The study investigated spatial immune heterogeneity in the tumor microenvironment and its possible drivers in a mouse model of tumors induced by human papillomaviruses (HPV) following immunotherapy. Gene expression was determined by RNA sequencing and mutations by whole exome sequencing. A comparison of different tumor areas revealed heterogeneity in immune cell infiltration, gene expression, and mutation composition. While the mean numbers of mutations with every impact on gene expression or protein function were comparable in treated and control tumors, mutations with high or moderate impact were increased after immunotherapy. The genes mutated in treated tumors were significantly enriched in genes associated with ECM metabolism, degradation, and interactions, HPV infection and carcinogenesis, and immune processes such as antigen processing and presentation, Toll-like receptor signaling, and cytokine production. Gene expression analysis of DNA damage and repair factors revealed that immunotherapy upregulated Apobec1 and Apobec3 genes and downregulated genes related to homologous recombination and translesion synthesis. In conclusion, this study describes the intratumoral immune heterogeneity, that could lead to tumor immune escape, and suggests the potential mechanisms involved.

The endorsement of conspiracy theories may be increased by subjectively perceived stress. Yet, it is not known whether this correlation is caused by the effects of the acute stress reaction on the brain or other psychological, social, or methodological factors. The effect of an experimentally induced acute stress reaction on conspiracy thinking was tested on a sample (n = 115) of students of medicine. Although the stress procedure caused a substantial increase in salivary cortisol, there was no significant effect on endorsing conspiracy theories or adopting conspiracy interpretations of novel information. The results confirmed no effect of the acute stress reaction on conspiracy thinking, suggesting it may be absent or weaker than expected. The study demonstrated the viability of psychophysiological experimental design in conspiracy research and may inspire further examination of the physiological mechanisms underlying susceptibility to conspiracy theories.

INTRODUCTION: Currently, limited data are available on long-term use of dupilumab to treat atopic dermatitis (AD) in a multinational real-world setting. The aim of this analysis was to report the interim 1-year data for patients with AD enrolled in the GLOBOSTAD registry, including treatment patterns, dupilumab effectiveness and safety, and healthcare burden. METHODS: GLOBOSTAD is an ongoing, 5-year, multinational, prospective, observational study of adult/adolescent (aged ≥ 12 years at baseline) patients with AD who initiated dupilumab in real-world settings according to their local country-specific prescribing guidelines. Outcomes were evaluated at baseline and at 3, 6 and 12 months and included Eczema Area and Severity Index (EASI) total score, SCORing Atopic Dermatitis (SCORAD) total score, percent body surface area (BSA) affected, Patient-Oriented Eczema Measure (POEM), Dermatology Life Quality Index (DLQI) total score for adults or Children's Dermatology Life Quality Index (CDLQI) total score for adolescents and pruritus Numeric Rating Scale (NRS) total score. RESULTS: At the interim 1-year cut-off (March 2023), 955 patients were enrolled in GLOBOSTAD, and follow-up data were obtained from 903 patients. After dupilumab initiation, mean improvements in effectiveness outcome measures from baseline to month 3 were EASI from 25.1 to 6.1, SCORAD 59.3 to 25.3, POEM 19.7 to 8.7, DLQI 13.7 to 5.3, CDLQI 12.2 to 2.7 and pruritus NRS 6.3 to 2.5, with each measure exceeding the minimal clinically important difference. These positive changes in effectiveness outcomes were maintained or further improved through 12 months since treatment initiation. AD-related hospitalizations and emergency room or urgent care facility visits decreased from 11.1% to 1.7% from baseline to month 12. CONCLUSIONS: In a multinational real-world setting, dupilumab demonstrated rapid, robust and sustained effectiveness in patients with moderate-to-severe AD across multiple disease domains, including AD signs, symptoms, quality of life and emergency/urgent care visits. Safety was consistent with the known dupilumab safety profile. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT03992417.

INTRODUCTION: A variable proportion of non-responders to cardiac resynchronization therapy (CRT) warrants the search for new approaches to optimize the position of the left ventricular (LV) lead and the CRT device programming. CineECG is a novel ECG modality proposed for the spatial visualization and quantification of myocardial depolarization and repolarization sequences. OBJECTIVE: The present study aimed to evaluate CineECG-derived parameters in different pacing modes and to test their associations with acute hemodynamic responses in CRT patients. METHODS AND RESULTS: CineECG was used to construct the average electrical path within the cardiac anatomy from the 12-lead ECG. CineECG and LV dP/dt max were tested in 15 patients with nonischemic dilated cardiomyopathy and left bundle branch block (QRS: 170 ± 17 ms; LVEF: 26 ± 5.5%) under pacing protocols with different LV lead localizations. The CineECG-derived path directions were computed for the QRS and ST-T intervals for the anteroposterior (Xh), interventricular (Yh), and apicobasal (Zh) axes. In a multivariate linear regression analysis with adjustment for the pacing protocol type, the ST-T path direction Yh was independently associated with the increase in dP/dt max during CRT, [regression coefficient 639.4 (95% confidence interval: 187.9-1090.9), p = 0.006]. In ROC curve analysis, the ST-T path direction Yh was associated with the achievement of a 10% increase in dP/dt max (AUC: 0.779, p = 0.002) with the optimal cut-off > 0.084 (left-to-right direction) with sensitivity 0.67 and specificity 0.92. CONCLUSION: The acute hemodynamic response in CRT patients was associated with specific CineECG repolarization sequence parameters, warranting their further testing as potential predictors of clinical outcomes.

This scoping review summarizes evidence regarding the impact of civic and community engagement of young people during the COVID-19 pandemic. Recognizing that the global pandemic not only brought challenges but also new opportunities to take a stance and to actively engage in communities and society, this review assesses the impact of the COVID-19 pandemic on young people's civic engagement across different cultural contexts and identifies key factors and processes that enable young people to engage with their community or society at large. We summarize evidence from 27 original research papers, one thought piece, and four reports conducted by global organizations such as the United Nations and OECD. Relevant research was conducted in the United States, Europe, China, Southeast Asia, South Africa, and New Zealand, addressing the development of leadership skills, civic responsibility, critical consciousness, civic and community engagement, as well as social integration. Key factors that facilitated civic engagement include national investments in online learning facilities, support for basic needs (such as education, health, and employment), and promotion and encouragement of local initiatives. The studies differed in their focus depending on the socio-cultural context encountered and future research needs to consider cultural variations and different demands on young people to inform effective practices for supporting young people's active engagement in society.

BACKGROUND: Limited licensed medications are available for multiple sclerosis (MS) in pediatric patients. OBJECTIVE: To evaluate the efficacy, safety, and tolerability of alemtuzumab in pediatric patients with relapsing-remitting multiple sclerosis (RRMS) and disease activity on prior disease-modifying therapies (DMTs). METHODS: LemKids was a multicenter, multinational, single-arm, open-label, switch (from ongoing DMT to alemtuzumab treatment) study in pediatric RRMS patients (aged 10-<18 years), with disease activity on DMT. The primary endpoint was a comparison of the number of new/enlarging T2 lesions on the magnetic resonance imaging of the brain between the prior-DMT period and alemtuzumab treatment. RESULTS: This study was prematurely terminated due to low enrollment and an European Medicines Agency Article-20 pharmacovigilance review of alemtuzumab in adult RRMS. Of 46 screened patients, 16 were enrolled; 12 completed prior-DMT treatment period; 11 received alemtuzumab of whom 7 completed treatment. Patients on alemtuzumab developed fewer new/enlarging T2 lesions compared with prior-DMT (7 vs 178, relative risk (95% confidence interval): 0.04 (0.01-0.14)). No significant pharmacodynamic changes or safety concerns were noted in this limited dataset. CONCLUSION: Alemtuzumab treatment was associated with a low number of new/enlarging T2 lesions in pediatric patients with RRMS and was safe and well tolerated in seven patients during infusion and the initial 4 months.
