Applying mathematical models, possible scenarios for the evolution of the outbreak in Germany are simulated. The results indicate that independent of the effectiveness of the current restrictive measures they might not be sufficient to mitigate the outbreak. Repeated shutdown periods or permanently applied measures over the winter could be successful alternatives.
European regulatory authorities request postmarketing safety and efficacy data for factor IX (FIX) products.
Collect additional clinical data from routine nonacog alfa use in children aged <6years with haemophilia B.
The EUREKIX registry included retrospective and prospective data collection phases. Safety was assessed via adverse drug reactions (ADRs)/adverse events (AEs) and events of special interest (ESIs) as the primary objective; efficacy was evaluated via annualised bleeding rates (ABRs).
The retrospective phase comprised 37 subjects. Of these, 25 had severe haemophilia B. (S)2Hydroxysuccinicacid One subject experienced 2 ADRs; another experienced 4 ESIs of hypersensitivity. Median ABR in subjects receiving a predominantly on-demand regimen (prophylaxis <50% of time; n=11) was 2.0; median ABR was 3.8 in those receiving predominantly prophylactic treatment (prophylaxis ≥50% of time; n=24). Joint bleeding was infrequent (median ABR, 0.4; n=35). The prospective phase included 26 subjects, with 17 continuing from the retrospective phase. A total of 20 subjects had severe haemophilia B. Three subjects experienced 7 treatment-related AEs; 3 experienced 4 ESIs. Median ABR was 4.5 and 1.1 in subjects who received predominantly on-demand (n=5) or prophylactic treatment (n=19), respectively; the overall median ABR for joint bleeding events was 0.0.
Overall, nonacog alfa treatment effectively controlled bleeding events, with no new safety signals identified. These data support the safety and efficacy of nonacog alfa in routine clinical settings in children aged <6years.
Overall, nonacog alfa treatment effectively controlled bleeding events, with no new safety signals identified. These data support the safety and efficacy of nonacog alfa in routine clinical settings in children aged less then 6 years.
To determine the optimal dose-volume constraint for laryngeal sparing using three commonly employed intensity modulated radiation therapy (IMRT) approaches in patients with oropharyngeal cancer treated to the bilateral neck.
Thirty patients with stage II-IVA oropharynx cancers received definitive radiotherapy with split-field IMRT (SF-IMRT) to the bilateral neck between 2008 and 2013. Each case was re-planned using whole-field IMRT (WF-IMRT) and volumetric modulated arc therapy (VMAT) and plan quality metrics and dose to laryngeal structures was evaluated. Two larynx volumes were defined and compared on the current study the Radiation Therapy Oncology Group (RTOG) larynx as defined per the RTOG 1016 protocol and the MDACC larynx defined as the components of the larynx bounded by the superior and inferior extent of the thyroid cartilage.
Target coverage, conformity, and heterogeneity indices were similar in all techniques. The RTOG larynx mean dose was lower with WF-IMRT than SF-IMRT (22.1 vs 25.8Gy; P&l-IMRT), whole-field IMRT (WF-IMRT) and volumetric arc therapy (VMAT). All three techniques provided good sparing of laryngeal structures and were able to achieve a mean larynx dose less then 33 Gy. There were no significant differences in dose to target structures or non-laryngeal organs at risk among techniques.Lamellar ichthyosis (LI) is a genetic skin disorder characterized by dark brown scales, palmoplantar hyperkeratosis, pain, and itching. LI severity could have implications in psychological aspects, causing depression and impairment in the quality of life (QoL) of patients. In this study, we used the Congenital Ichthyosis Severity Index, the Depression Beck Inventory-II (DBI-II), and the Dermatologic Life Quality Index (DLQI) to assess severity, level of depression, and impairment in QoL in a group of patients with LI. We observed that the majority of the patients presented a high severity level concerning the presence of scales (57.7%), while for erythema and alopecia, the severity was less 80% of the analyzed patients presented depression, while only 20.8% of individuals of the control group presented it (P less then .001, OR = 15.2). While for QoL, only 4.3% of the patients did not exhibit any impairment. Finally, the increase in the score obtained in DBI-II was correlated with the DLQI score (rs = 0.663, P = .0014). Our results suggest that patients with LI have an increased risk of suffering depression and impairment in their QoL; thus, the management of their disease should be performed from a multidisciplinary perspective to improve the global aspects of their lives.Psoriasis is a multifactorial and chronic skin disorder. It is a recurrent disease that requires incessant therapy. Psoriasis treatment includes topical and systemic routes using synthetic drugs that lead to severe unwanted adverse effects. Herbal therapy is widely used for thousands of years in countries like China and India. The use of herbal therapy in the developed region enhanced to a great extent and showed better efficacy towards psoriasis alone or as adjuvant to synthetic therapy. Herbal medicines have gained great attention in the treatment of psoriasis due to their lesser side effects compared to synthetic drugs. In this review, the various plant sources which have been found effective in psoriasis and can be used to develop novel therapeutics have been discussed. The mechanisms by which the phytoconstituents elicit anti-psoriatic activity and various research studies that have proven the effectiveness of these natural products have also been compiled in this review.
Acute coronary syndrome (ACS) may induce cardiovascular death. The correlation of mast cells related microRNAs (miRs) with risk of ACS has been investigated. We explored regulatory mechanism of miR-335-5p on macrophage innate immune response, atherosclerotic vulnerable plaque formation, and revascularization in ACS in relation to Notch signaling.
ACS-related gene microarray was collected from Gene Expression Omnibus database. After different agomir or antagomir, or inhibitor of Notch signaling treatment, IL-6, IL-1β, TNF-α, MCP-1, ICAM-1, and VCAM-1 levels were tested in ACS mice. Additionally, Notch signaling-related genes and matrix metalloproteinases (MMPs) were measured after miR-335-5p interference. Finally, mouse atherosclerosis, lipid accumulation, and the collagen/vessel area ratio of plaque were determined.
miR-335-5p targeted JAG1 and mediated Notch signaling in ACS. miR-335-5p up-regulation and Notch signaling inhibition reduced expression of JAG1, Notch pathway-related genes, IL-6, IL-1β, TNF-α, MCP-1, ICAM-1, VCAM-1, and MMPs, but promote TIMP1 and TIMP2 expression.
