Psoriasis dermatitis, a common phenotype of early forms of both psoriasis and atopic dermatitis in children: A prospective multicenter study.

BACKGROUND: Psoriasis (Ps) and atopic dermatitis (AD) are chronic systemic immune-mediated diseases that can coexist in an overlapping condition called psoriasis dermatitis (PD). PD patients have intermediate lesions with characteristics of both Ps and AD. PD is very rare in adults but much more frequent in children. Little is known, however, about the course of PD in the pediatric population. The aim of this study was to evaluate the percentage of PD cases in children that evolved to a definite form of Ps or AD and to identify any clinical or epidemiological variables that could predict the course of the disease. METHODS: We performed a prospective multicenter cohort study of children diagnosed with PD between January 2018 and December 2020. We collected participants' clinical and epidemiological characteristics, and pediatric dermatologists determined the percentage of participants who developed Ps or AD. RESULTS: The study included 24 children with PD, with a median age of 7.0 years. After a median follow-up period of 31 months, 83.3% of cases had evolved to a definite form of Ps or AD (44.4% to Ps and 38.9% to AD). Younger age and family history of Ps were associated with progression to AD. Participants who progressed to AD or Ps had a longer follow-up than those with an unchanged PD diagnosis. CONCLUSIONS: Given sufficient time, a large percentage of PD cases in children will evolve into Ps or AD. Long-term clinical follow-up is necessary for a correct diagnosis.

Abscopal downstaging of intermediate stage hepatocellular via combination cryoablation and immunotherapy with complete pathologic response.

The abscopal effect is a rare phenomenon characterized by disease regression in distant sites after tumoral locoregional therapy. Locoregional therapy, such as cryoablation, can induce an antitumor immunological response, potentially improving outcomes in cancer patients receiving immunotherapy. This report describes a patient with multifocal hepatocellular carcinoma who progressed through multiple locoregional therapies, was initially unresponsive to immunotherapy, and later achieved rapid and sustained disease regression with a combination cryoablation and immunotherapy. A 5-year sustained complete tumor response successfully bridged to liver transplantation.

Deep Neck Infection: A Case of Retropharyngeal Abscess.

The incidence of retropharyngeal abscesses has been decreasing since the introduction of antibiotic therapy, and it is currently a rare diagnosis in adults, although there are some recent cases in the literature. Given its seriousness, if not treated promptly, the infection can progress rapidly and its complications can be fatal, making it a serious health problem. A 79-year-old woman presented at her primary care center with complaints of persistent odynophagia for about two weeks and rapidly progressive dysphagia in five days, initially for solids and later for solids and liquids. On observation, she had difficulty swallowing saliva and presented a painful mass in the bilateral anterior submental and anterior cervical region. Due to the rapid progression of symptoms and the findings of the physical examination, the patient was referred to the emergency department for a suspected abscess or cervical mass. In the emergency department, a cervical CT scan was performed, which revealed a retropharyngeal abscess measuring approximately 7 x 6 x 4 cm, involving the right carotid artery and internal jugular vein, with compression of the internal jugular vein. The patient was admitted to the otorhinolaryngology department, where intravenous antibiotic therapy with third-generation cephalosporin and clindamycin was initiated. She underwent exploration in the operating room to determine the cause of the abscess and transoral drainage of the already spontaneously draining abscess. After completing antibiotic therapy, a follow-up CT scan showed complete resolution of the abscess without suggestive masses of neoplasm or foreign bodies, therefore, the cause of the abscess has not been identified.  The most frequent cause of retropharyngeal abscess in adults is dental septic foci and another commonly described cause is the ingestion of foreign bodies such as fish bones or chicken bones. Early diagnosis of this condition is crucial, as delays in treatment initiation can lead to the progression of infection into the deep cervical spaces, resulting in serious complications such as mediastinitis, pericarditis, jugular vein thrombosis, sepsis, laryngeal edema, conditions with a high degree of morbidity and mortality. Therefore, it is important for any doctor to be aware of warning signs and symptoms in patients who present such symptoms, especially primary care doctors, who are the first gateway to health services and to whom patients often turn first. This case report shows the importance of suspicion and subsequent referral for timely diagnosis and treatment.

Integrated control of neglected tropical diseases in Brazil: document review of a national campaign in light of WHO recommendations.

Objective: To describe the results of a national campaign aimed at the integrated control of neglected tropical diseases in Brazil in light of the World Health Organization (WHO) official documentation related to the integration of strategies for the prevention, control, and elimination or eradication of neglected tropical diseases. Methods: A document review that included official WHO documents published between 2007 and 2020 and campaign results extracted from the official technical report produced by the Brazilian Ministry of Health. Results: The integrated control of neglected tropical diseases was gradually incorporated in the WHO documentation over time. Preventive chemotherapy through mass drug administration, intensified case management, and integrated vector management were extensively recommended as strategies for integrated control. The Brazilian campaign was carried out in four iterations between 2013 and 2017. Children aged 5 to 14 years enrolled in municipal public schools nationwide were targeted. In summary, a total of 1 074 and 73 522 new cases of leprosy and trachoma, respectively, were detected. Nearly 18 million doses of preventive chemotherapy for soil-transmitted helminthiasis were administered. More than 700 cases of schistosomiasis were diagnosed and treated. Conclusions: The integrated strategies implemented in Brazil throughout the campaign generated results aligned with the WHO recommendations for the control of neglected tropical diseases, especially those regarding mass drug administration, active case detection, and intensified case management. Therefore, the continuity of the campaign with adequate evaluation tools must be encouraged as a constant public health policy in the Brazilian government agenda.

Diagnostic test accuracy of novel biomarkers for lupus nephritis-An overview of systematic reviews.

INTRODUCTION: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with multiorgan inflammatory involvement and a mortality rate that is 2.6-fold higher than individuals of the same age and sex in the general population. Approximately 50% of patients with SLE develop renal impairment (lupus nephritis). Delayed diagnosis of lupus nephritis is associated with a higher risk of progression to end-stage renal disease, the need for replacement therapy, and mortality. The initial clinical manifestations of lupus nephritis are often discrete or absent and are usually detected through complementary tests. Although widely used in clinical practice, their accuracy is limited. A great scientific effort has been exerted towards searching for new, more sensitive, and specific biomarkers in recent years. Some systematic reviews have individually evaluated new serum and urinary biomarkers tested in patients with lupus nephritis. This overview aimed to summarize systematic reviews on the accuracy of novel serum and urinary biomarkers for diagnosing lupus nephritis in patients with SLE, discussing how our results can guide the clinical management of the disease and the direction of research in this area. METHODS: The research question is "What is the accuracy of the new serum and urinary biomarkers studied for the diagnosis of LN in patients with SLE?". We searched for systematic reviews of observational studies evaluating the diagnostic accuracy of new serum or urinary biomarkers of lupus nephritis. The following databases were included: PubMed, EMBASE, BIREME/LILACS, Scopus, Web of Science, and Cochrane, including gray literature found via Google Scholar and PROQUEST. Two authors assessed the reviews for inclusion, data extraction, and assessment of the risk of bias (ROBIS tool). RESULTS: Ten SRs on the diagnostic accuracy of new serum and urinary BMs in LN were selected. The SRs evaluated 7 distinct BMs: (a) antibodies (anti-Sm, anti-RNP, and anti-C1q), (b) cytokines (TWEAK and MCP-1), (c) a chemokine (IP-10), and (d) an acute phase glycoprotein (NGAL), in a total of 20 review arms (9 that analyzed serum BMs, and 12 that analyzed BMs in urine). The population evaluated in the primary studies was predominantly adults. Two SRs included strictly adults, 5 reviews also included studies in the paediatric population, and 4 did not report the age groups. The results of the evaluation with the ROBIS tool showed that most of the reviews had a low overall risk of bias. CONCLUSIONS: There are 10 SRs of evidence relating to the diagnostic accuracy of serum and urinary biomarkers for lupus nephritis. Among the BMs evaluated, anti-C1q, urinary MCP-1, TWEAK, and NGAL stood out, highlighting the need for additional research, especially on LN diagnostic panels, and attempting to address methodological issues within diagnostic accuracy research. This would allow for a better understanding of their usefulness and possibly validate their clinical use in the future. REGISTRATION: This project is registered on the International Prospective Registry of Systematic Reviews (PROSPERO) database (CRD42020196693).

In vitro Selection of High Affinity DNA and RNA Aptamers that Detect Hepatitis C Virus Core Protein of Genotypes 1 to 4 and Inhibit Virus Production in Cell Culture.

Hepatitis C virus (HCV) core is a highly conserved and multifunctional protein that forms the viral capsid, making it an attractive target for HCV detection and inhibition. Aptamers are in vitro selected, single-stranded nucleic acids (RNA or ssDNA) with growing applicability in viral diagnostics and therapy. We have carried out DNA and RNA in vitro selection against six different variants of HCV core protein: two versions of the full-length protein of genotype 1, and the hydrophilic domain of genotypes 1 to 4. The aptamer populations obtained were analyzed by means of Ultra-Deep Sequencing (UDS), the most abundant sequences were identified and a number of highly represented sequence motifs were unveiled. Affinity (measured as the dissociation constant, Kd) of the most abundant DNA and RNA aptamers were quantified using Enzyme-Linked OligoNucleotide Assay (ELONA)-based methods. Some aptamers with nanomolar or subnanomolar Kd values (as low as 0.4 nM) were the common outcome of DNA and RNA selections against different HCV core variants. They were tested in sandwich and competitive biosensor assays, reaching a limit of detection for HCV core of 2 pM. Additionally, the two most prevalent and high affinity aptamers were assayed in Huh-7.5 reporter cell lines infected with HCV, where they decreased both the viral progeny titer and the extracellular viral RNA level, while increasing the amount of intracellular viral RNA. Our results suggest that these aptamers inhibit HCV capsid assembly and virion formation, thus making them good candidate molecules for the design of novel therapeutic approaches for hepatitis C.

Effect of solvent-solvent partition on antioxidant activity and GC-MS profile of Ilex guayusa Loes. leaves extract and fractions.

The use of guayusa (Ilex guayusa Loes.) leaves as functional food has increase recently. This work discusses the antioxidant activity and volatile compounds of guayusa leaves extract and fractions. The methanol crude extract was obtained by maceration, subsequently hexane, chloroform, ethyl acetate, and aqueous fractions were collected by solvent-solvent partition. Total phenolic content (TPC), total flavonol/flavone content (TFC), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, and ferric reducing antioxidant power (FRAP) were measured by ultraviolet-visible (UV-Vis) spectrophotometry. The results revealed that ethyl acetate fraction showed highest inhibition against DPPH radical (93.86 ± 0.95%) at 500 µg/mL, and reduce the ferric-tripyridyltriazine complex (Fe3+-TPTZ) at 1619.81 mg trolox equivalent (TE)/g, followed by aqueous fraction. This bioactivity could be related to phenolic acids, flavones and flavonols content, as well as the caffeine, dodecanoic acid isopropyl ester, caffeic acid, and malic acid identified by gas chromatography-mass spectrometry (GC-MS). These findings support the antioxidant properties of this plant material.

Anti-inflammatory potential of processing Vernonanthura patens (Kunth) H. Rob. leaves aqueous extract.

Folk medicine uses decoctions of Vernonanthura patens (Kunth) H. Rob. leaves for healing wounds, and moderate pains. In this study, anti-inflammatory activity of decocted aqueous extract and its fractions is discussed. The fractions were obtained by liquid-liquid extraction in a separating funnel with solvents of increasing polarity: hexane, chloroform, and ethyl acetate. Antioxidant capacity, COX1, and COX2 cyclooxygenase inhibitory activities of aqueous extract (A1), aqueous (A2), and ethyl acetate (A3) fractions were assessed. A3 revealed the highest flavonoid content, and DPPH (2,2-diphenyl-1-picrylhydrazyl) scavenging activity. Nevertheless, no significance differences were observed between IC50 values of A1 and A2, and A1 showed anti-inflammatory activity with potential selectivity against COX2 enzyme, but intermediate COX1 inhibition. Further experiments are required to complement the remarkable anti-inflammatory effect of assessed aqueous extract. These results support the medicinal use of this plant species and indicate that A1 can be used as raw material for prospective nutraceutical products.

Scaffold Hopping to Imidazo[1,2-a]pyrazin-8-one Positive Allosteric Modulators of Metabotropic Glutamate 2 Receptor.

Glutamate hyperfunction is implicated in multiple neurological and psychiatric diseases. Activation of the mGlu2 receptor results in reduced glutamate release and decreased excitability representing a promising novel therapeutic agent for the treatment of disorders such as epilepsy, schizophrenia, mood, anxiety, and other neuropsychiatric disorders. We have previously reported substantial efforts leading to potent and selective mGlu2 PAMs from different chemical series. Herein, the discovery and optimization of a novel series of imidazopyrazinone mGlu2 PAMs are reported. This new scaffold originated from computational searching of fragment databases and comparison with our previously explored scaffolds. Optimization guided by our robust understanding of SAR from former series led to potent, selective, and brain-penetrant compounds.

Effect of Cocoa Bean Shell Addition on Metabolite Profile and Antioxidant Activity of Herbal Infusions.

Cocoa bean shell (CBS) is a by-product with aromatic characteristics that can enhance the aroma and bioactivity of herbal infusions. This study was aimed to determine the effect of the addition of cocoa bean shell on the metabolite profile and antioxidant activity of infusions made with Ilex guayusa and Vernonanthura patens and their mixtures. Metabolite profile was analyzed by gas chromatography-mass spectrometry combined with multivariate analysis. Total polyphenol content and flavonoids were determined by the Folin-Ciocalteu method and by the flavonoid-AlCl3 complex, respectively. Antioxidant activities were measured by the decolorization assay of the 2,2-diphenyl-1-picrylhydrazyl radical and the ferric reducing antioxidant power. The results revealed that the addition of CBS increases the content of phenolic acids in the infusions (caffeic acid, 4-hydroxybenzoic acid, and pyrocatechol). Nonetheless, the antioxidant activity of the infusions decreased with the addition of CBS (16.21 to 2.74 TEAC). Carboxylic acids and derivatives, major compounds present in the infusions prepared with V. patens, were the metabolites that showed the highest correlation with the antioxidant activity. This study suggests that the infusions made with CBS present a profile of metabolites different from the infusions of I. guayusa, V. patens, and their mixtures.

Spiro-oxindole Piperidines and 3-(Azetidin-3-yl)-1H-benzimidazol-2-ones as mGlu2 Receptor PAMs.

Starting from two weak mGlu2 receptor positive allosteric modulator (PAM) HTS hits (4 and 5), a molecular hybridization strategy resulted in the identification of a novel spiro-oxindole piperidine series with improved activity and metabolic stability. Scaffold hopping around the spiro-oxindole core identified the 3-(azetidin-3-yl)-1H-benzimidazol-2-one as bioisoster. Medicinal chemistry optimization of these two novel chemotypes resulted in the identification of potent, selective, orally bioavailable, and brain penetrant mGluR2 PAMs.

Effect of resin content and pressing temperature on banana pseudo-stem particle boards properties using full factorial design.

The volume of global gross banana exports reached a record of 117.9 million tonnes in 2015 (FAO 2017), which agro-industrial wastes derived as the pseudo-stem, rachis and leaves do not have an industrial application instead they are discarded. This research study applies full factorial design and response surface methodology to determine the effect of pressing temperature and resin content on density (D), moisture (M), water absorption (WA), water swelling (WS), module of rupture (MOR), module of elasticity (MOE) and formaldehyde content (FC) of particle board made of banana pseudo-stem. A 22 factorial design was performed, factors considered were resin and temperature. The low level of resin was 15% in the coarse fiber (CF) and 35% in fine fiber (FF); high level as 25% CF and 45% FF. Temperature levels were 150ºC and 170ºC respectively. The boards met all quality parameters except ones with low resin content that didn't meet WS parameter. Furthermore, resin affected positively on WA, FC and MOE, and decreased D, WS and MOR values. Meanwhile, temperature affected negatively on D, WS, and increased FC, WA, MOE, MOR properties; none of the factors affected M response. Process conditions were optimized to 162.61°C and 43.15% FF, 23.97% CF.

Evaluation of a Series of ß-Secretase 1 Inhibitors Containing Novel Heteroaryl-Fused-Piperazine Amidine Warheads.

Despite several years of research, only a handful of ß-secretase (BACE) 1 inhibitors have entered clinical trials as potential therapeutics against Alzheimer's disease. The intrinsic basic nature of low molecular weight, amidine-containing BACE 1 inhibitors makes them far from optimal as central nervous system drugs. Herein we present a set of novel heteroaryl-fused piperazine amidine inhibitors designed to lower the basicity of the key, enzyme binding, amidine functionality. This study resulted in the identification of highly potent (IC50 ≤ 10 nM), permeable lead compounds with a reduced propensity to suffer from P-glycoprotein-mediated efflux.

Inhibition of the Alanine-Serine-Cysteine-1 Transporter by BMS-466442.

Experiment and modeling were combined to understand inhibition of the alanine-serine-cysteine-1 (asc1) transporter. The structure-activity relationship (SAR) was explored with synthesis of analogues of BMS-466442. Direct target interaction and binding site location between TM helices 6 and 10 were confirmed via site directed mutagenesis. Computational modeling suggested the inhibitor binds via competitive occupation of the orthosteric site while also blocking the movement of TM helices that are required for transport.
