Between 5 and 25% of patients with cutaneous lupus erythematosus (CLE) can progress to systemic lupus erythematosus (SLE) during the course of the disease. There is no clear predictive guideline for the progression of CLE to SLE.
Lupus erythematosus (LE), a chronic autoimmune disease, has a wide spectrum of manifestations. On one side of the spectrum is CLE, in which patients only display skin lesions. On the other side of the spectrum is SLE, which develops severe systemic involvement. CLE has even been considered as a separate entity from LE, while CLE is also proposed to be associated with SLE. In this review, the authors will describe the relationship between CLE and SLE; summarize the incidence, risk factors, systemic involvement, and management of patients who transition to SLE. The literature search was conducted mainly through PubMed from March to July 2020.
The identification of clinical characteristics and biomarkers in patients facing risk of developing SLE and monitoring the disease on a regular basis are essential to promptly manage and hopefully prevent transition to the systemic form.

However, SLC-0111, now in phase Ib/II clinical trials, was developed based on the excellent agreement between the in vitro, in vivo and more recently, in-patient data.Chiliadenus montanus is a medicinal plant that grows in Sinai Peninsula in Egypt. Phytochemical investigation of C. montanus methanolic extract led to the isolation of five methoxy flavonoids; Chrysosplenol-D (1), 5,7,4'-trihydroxy- 3,3'-dimethoxy flavone (2), 5,7-dihydroxy -3,3',4'-trimethoxyflavone (3), Bonanzin (4), 3,5,6,7,4'-pentamethoxy flavone (5), a sesquiterpene, Cryptomeridiol (6) and stigmast-5,22-dien-3-O-β-D-glucopyranoside (7). The anti-inflammatory activity of compounds 2 and 5 was assessed in vitro on CaCo2 cells stimulated by lipopolysaccharide (LPS). Both compounds downregulated LPS-induced expression of inflammatory cytokines; tumor necrosis factor alpha (TNFα), interleukin 1β (IL1β), nuclear factor kappa B (NFκB), cyclooxygenase 1 (Cox1), cyclooxygenase 2 (Cox2), and 5-lipoxygenase (5Lox). In vivo, both compounds significantly decreased paw edema thickness in rats relative to carrageenan, showing better anti-inflammatory activity than celecoxib (36.98%) after 1 h (46.60% and 48.11%, respectively). An in silico study was performed, where both compounds were docked into the active site of the crystal structure of the human Cox2 enzyme.
Glioblastoma is a primary brain tumor with a poor prognosis despite multimodal therapy including surgery, radiotherapy and alkylating chemotherapy. Novel therapeutic options are therefore urgently needed; however, there have been various drug failures in late-stage clinical development. The proteasome represents a key target for anti-cancer therapy as successfully shown in multiple myeloma and other hematologic malignancies.
This review article summarizes the preclinical and clinical development of proteasome inhibitors in the context of glioblastoma.
Early clinical trials with bortezomib ended with disappointing results, possibly because this agent does not cross the blood-brain barrier. In contrast to bortezomib and other proteasome inhibitors, marizomib is a novel drug that displays strong inhibitory properties on all enzymatic subunits of the proteasome and, most importantly, crosses the blood-brain barrier, making it a potentially very active novel agent against intrinsic brain tumors. While preclinical studies have demonstrated significant anti-glioma activity, its clinical benefit has yet to be proven. this website Exploiting the biological effects of proteasome inhibitors in combination with other therapeutic strategies may represent a key next step in their clinical development.

Fatigue is one of the most consistent and distressing symptoms reported by adolescent/young adult (AYA) oncology patients. Bright white light (BWL) is used to treat fatigue in adult oncology but has not been explored in AYA oncology patients. The purpose of the current study was to determine the feasibility and acceptability of BWL for AYA who were receiving cancer-directed therapy.
51 AYA patients with newly diagnosed solid tumors, including lymphoma.
Participants were randomized to dim red light (DRL, n =25) or BWL (n=26) from devices retrofitted with adherence monitors for 30minutes upon awakening daily for 8weeks. Side effects were assessed via modified Systematic Assessment for Treatment-Emergent Effects (SAFTEE). Participants completed the PedsQL Multidimensional Fatigue Scale.
Of patients approached, 73% consented and participated. Mean adherence was 57% of days on study with 30.68 average daily minutes of usage. BWL did not cause more extreme treatment-emergent effects over DRL. Patients in the BWL group demonstrated significant improvement on all fatigue outcomes by both self-report and parent proxy report, which was not observed in the DRL group.
This is the first study to evaluate the feasibility and acceptability of light therapy to reduce fatigue in AYA patients receiving cancer-directed therapy. These findings demonstrate the feasibility and acceptability of the intervention and provide preliminary evidence of the potential benefits of BWL, which warrants further study in a confirmatory efficacy trial. ClinicalTrials.gov Identifier Number NCT02429063.

This study included 46 drug-naive children aged 4-17 y diagnosed with ASD. The Autism Behavior Checklist (AuBC), Children's Sleep Habits Questionnaire (CSHQ), and Children's chronotype questionnaire (CCQ) were filled out before and at the end of the COVID-19 mandated home confinement by the children's parents. Children with ASD during the home confinement reported higher chronotype scores, i.e., eveningness chronotype, sleep problems, and autism symptom scores compared to the normal non-hone confinement state. The chronotype score and sleep problems of children with ASD during the home confinement period varied according to the AuBC score. The sleep problems of the children with ASD during the home confinement period mediated the relationship between chronotype score and severity of autism symptoms. It is essential to validate the role of the mediator effect of sleep problems and chronotype in larger samples of children with ASD with restricted to home confinement during the pandemic period. If sleep problems can be controlled with parental education, pharmacotherapy, and psychotherapeutic interventions, the impact on children with ASD of home confinement can be reduced.Coronavirus disease 2019 (COVID-19) has been a pandemic disease of which the termination is not yet predictable. Currently, researches to develop vaccines and treatments is going on globally to cope with this disastrous disease. Main protease (3CLpro) from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is one of the good targets to find antiviral agents before vaccines are available. Some flavonoids are known to inhibit 3CLpro from SARS-CoV which causes SARS. Since their sequence identity is 96%, a similar approach was performed with a flavonoid library. Baicalin, herbacetin, and pectolinarin have been discovered to block the proteolytic activity of SARS-CoV-2 3CLpro. An in silico docking study showed that the binding modes of herbacetin and pectolinarin are similar to those obtained from the catalytic domain of SARS-CoV 3CLpro. However, their binding affinities are different due to the usage of whole SARS-CoV-2 3CLpro in this study. Baicalin showed an effective inhibitory activity against SARS-CoV-2 3CLpro and its docking mode is different from those of herbacetin and pectolinarin. This study suggests important scaffolds to design 3CLpro inhibitors to develop antiviral agents or health-foods and dietary supplements to cope with SARS-CoV-2.
Vulvovaginal candidiasis (VVC) is a common fungal infection caused by predominantly
, and is diagnosed in up to 40% of women with vaginal complaints in the primary care setting. Approximately 75% of women experience at least one episode during their reproductive years.
Ibrexafungerp is an orally active, semi-synthetic triterpenoid glucan synthase inhibitor under development for treatment and prevention of VVC. We present the chemistry, mechanism of action, pharmacology, microbiology, and results from clinical studies with ibrexafungerp in women with VVC.
Ibrexafungerp addresses several unmet needs with existing antifungal drugs as a first in a new class of antifungal agents with a novel mechanism of action demonstrating no antifungal cross resistance with azoles, and fungicidal activity against
spp., including fluconazole-resistant species. Some of the key attributes of ibrexafungerp related to VVC include oral one-day dosing, high tissue penetration, enhanced activity at low pH seen in the vagina, low risk for clinically significant drug-drug interactions, and a low risk of adverse events.
