Efficacy and safety of tralokinumab in the treatment of head and neck pattern atopic dermatitis: A multicentre study of 12 patients.

BACKGROUND/OBJECTIVES: The evaluation of the efficacy and safety of new molecules for atopic dermatitis (AD) in real clinical practice is very important to obtain information that clinical trials (EECC) lack. The pattern of AD in the head and neck (H&N) continues to be a challenge in treatment today, despite the new molecules, and real-life data on the use of tralokinumab is still missing. This is the first daily practice study of tralokinumab treatment in patients with H&N AD pattern. The objective is to evaluate the efficacy and safety of tralokinumab in the short term (16 weeks) in patients with AD with H&N pattern, for the first time. METHODS: A multicentre prospective observational study was conducted, including patients with moderate-severe AD and H&N pattern who started tralokinumab treatment in four hospitals in Andalusia. Values of severity and quality of life scales, as well as patient-reported outcomes (PROs), were collected at baseline and at Weeks 4 and 16. Safety events were also recorded. RESULTS: Twelve patients were included. An improvement was observed in all efficacy and quality of life parameters evaluated at 16 weeks with respect to the baseline. No serious adverse events were recorded. CONCLUSIONS: In real clinical practice, tralokinumab is demonstrated to be an effective and safe treatment for patients with AD and H&N pattern at short term.

Low similarity between parasite communities of ten sympatric carangid species.

Host phylogeny and ecological convergence are two factors thought to influence the structure of parasite communities. The aims of this study were to determine the diversity of metazoan parasites of 10 sympatric fish species of the family Carangidae from the southeastern Gulf of California, and to analyze their similarity at infracommunity and component community levels, in order to determine if the host species, particularly those congeneric with similar ecological characteristics, exhibit similar assemblages of parasites. In total, 874 fish specimens were examined and 40 parasite species were identified. The component community was composed by 21 parasite species in Caranx caninus, 20 in C. caballus, 11 in C. vinctus, five in Chloroscombrus orqueta, four in Carangoides otrynter, seven in Hemicaranx leucurus, eight in Selene brevoortii, 14 in S. peruviana, and 11 in Trachinotus rhodopus. The metazoan parasite communities of C. vinctus, Ch. orqueta, H. leucurus, and S. brevoortii are reported here for the first time. The parasite communities of the remaining six carangid species have been reported from regions other than the Gulf of California. All fish species differed significantly regarding the diversity of their parasite infracommunities. This possibly is due to different patterns of habitat use among fish species, and because of the differential host specificity among parasite taxa. Nonetheless, when the analysis was restricted to common parasite species, some fish showed similar parasite infracommunities, particularly congeners of the genus Selene as well as C. caballus and C. vinctus. The component communities of species of Selene were highly similar (>65%), but the three species of Caranx were not. This result supports the hypothesis that congeneric fish species with similar ecological filters harbor similar parasite communities. However, the difference observed between C. caninus and C. caballus suggests that these species, despite being evolutionary and ecologically related, have different physiological or immunological characteristics (compatibility filters) that may result in different parasite communities.

In vitro characterization of a novel resin-based restorative material containing alkaline fillers.

OBJECTIVE: In this study, a comparative evaluation of the physicochemical properties of Cention N and other direct restorative materials was performed. Three restorative materials-a resin-modified glass ionomer (Fuji II LC), an alkasite-based resinous material (Cention N), and a resin composite (Tetric N Ceram)-were characterized in terms of degree of conversion, Knoop hardness number (KHN) ratio, flexural strength, elastic modulus, water sorption, water solubility, microshear bond strength to dentin, immediate microleakage, and radiopacity. METHODOLOGY: The microshear bond strength to dentin and microleakage of Cention N were evaluated with and without the application of an adhesive system (Tetric N Bond Universal). A one-way ANOVA test was used to analyze the data in terms of degree of conversion, KHN ratio, water sorption, water solubility, microshear bond strength to dentin, and radiopacity. A two-way ANOVA test (carried out considering the material type and ethanol aging as factors) was used to analyze the data in terms of flexural strength and elastic modulus. The Kruskal-Wallis test was used to statistically analyze the data on microleakage. A significance level of α=0.05 was used for all tests. RESULTS: Fuji II LC was found to have the highest degree of conversion, water sorption, and microleakage, as well as the lowest flexural strength. Cention N had the highest solubility; when used with an adhesive system, it achieved bond strength and microleakage similar to those of the Tetric N Ceram composite. Tetric N Ceram had the highest degree of conversion, KHN ratio, and radiopacity. Conclusion: The properties of Cention N validate its efficacy as an alternative direct restorative material when used in conjunction with an adhesive system.

Depression and opinion of dental students regarding the hybrid learning model during the COVID-19 pandemic.

BACKGROUND: The global spread of COVID-19 forced schools at all educational levels to close, which was repeated in more than 60 countries. In addition, the COVID-19 pandemic has affected the mental health of dental students world wide. This study hypothesizes that the prevalence of depression in dental students from El Salvador is higher than that reported in studies from Europe, Asia, and North America. METHODS: This study was an online cross-sectional survey performed at the Faculty of Dentistry of the University of Salvador. The PHQ-9 questionnaire was applied to know the level of depression of the students, and a questionnaire focused on learning the opinion of the students on the hybrid teaching model adopted. Approximately 450 students participated in both questionnaires. RESULTS: Regarding the levels of depression present in the students, 14% had minimal depression, 29% had medium depression, 23% had moderate depression and, 34% had severe depression. The students had an excellent opinion regarding the hybrid learning model. CONCLUSIONS: The prevalence of depression in dental students in El Salvador seems to be higher than that reported in studies in non-Latin American countries. Therefore, universities must generate care plans for mental health to avoid these harmful effects on students during future contingencies.

Socio-Emotional Competencies Required by School Counsellors to Manage Disruptive Behaviours in Secondary Schools.

This article identifies the socio-emotional competencies of school counsellors working with children and adolescents. The aim is to address problems related to mental health and conflict and to implement training programmes. The study sample was composed of 149 counsellors working in schools. The instruments used were the CCPES-II (questionnaire on teacher competences) and a series of open-ended questions on conflict resolution. A mixed methodology was used, with a concurrent triangulation design with two phases: a quantitative one (QUAN) and a qualitative one (QUAL). Univariate, bivariate, and correlation quantitative analyses were performed. Parametric and non-parametric tests were applied depending on the number of dependent and independent variables. The qualitative analysis was performed with the NVivo 12 computer programme, which determines word frequencies using a classic content analysis. The results confirm the relationship between socio-emotional training and rapid response to school conflict; the generalised view that conflicts are difficult to anticipate and, thus, to prevent; and the demand for specific training in socio-emotional competences, intervention strategies, more specialised school staff, more time for intervention with and support for families, and more socio-professional recognition.

Redescription of Lernaeenicus longiventris Wilson, 1917 (Copepoda: Pennellidae) Parasitic on the Pacific Crevalle Jack Caranx caninus (Carangidae) Through Morphological and Molecular Analyses.

PURPOSE: The present study deals with a redescription of the copepod Lernaeenicus longiventris Wilson, 1917 (Copepoda: Siphonostomatoida: Pennellidae) found on the Pacific crevalle jack Caranx caninus Günther, using morphological and molecular analyses. METHODS: Fish were collected off Mazatlán Port (23° 12' N, 106° 26' W), in the State of Sinaloa, Mexico (southeastern Gulf of California). The copepods were morphologically analyzed by light microscopy. Sequences of the COI mtDNA gene were generated for the first time for this species. These sequences were compared to COI sequences from six species of Lernaeenicus available in GenBank. RESULTS: The specimens of the present study exhibited a cephalosome without apparent lateral processes, which were originally described for L. longiventris. No remarkable differences were observed with previous descriptions regarding appendages and body proportions. The phylogenetic tree based on COI sequences showed that L. longiventris was closer to L. radiatus although with low bootstrap values support in ML tree, both species formed a sister clade of L. sprattae. CONCLUSIONS: Lernaeenicus longiventris is the unique species of the genus in the Mexican Pacific and the Gulf of California, and also the unique species of Lernaeenicus infecting C. caninus. Molecular data of L. longiventris from host and locality type are required to avoid misidentification of this species.

Efficacy and safety of anakinra and canakinumab in PSTPIP1-associated inflammatory diseases: a comprehensive scoping review.

Introduction: This scoping review explores the effectiveness of IL-1 pathway inhibitors in managing PSTPIP1-associated inflammatory diseases (PAID). These diseases are marked by abnormal IL-1 pathway activation due to genetic mutations. Methods: Our methodology adhered to a pre-published protocol and involved a thorough search of MEDLINE and EMBASE databases up to February 2022, following the Joanna Briggs Institute Reviewer's Manual and the PRISMA Extension for Scoping Reviews. The review included studies reporting on IL-1 pathway inhibitor use in PAID patients. Results: From an initial pool of 5,225 articles, 36 studies involving 43 patients were selected. The studies predominantly used observational designs and exhibited diversity in patient demographics, treatment approaches, and outcomes. Anakinra and canakinumab demonstrated promise in treating sterile pyogenic arthritis, pyoderma gangrenosum, and acne (PAPA) and PSTPIP1-associated myeloid-related-proteinemia inflammatory (PAMI) syndromes, with scant data on other syndromes. Notably, there was a paucity of information on the adverse effects of these treatments, necessitating cautious interpretation of their safety profile. Conclusion: Current evidence on IL-1 pathway inhibitors for PAID is primarily from observational studies and remains limited. Rigorous research with larger patient cohorts is imperative for more definitive conclusions. Collaborative efforts among specialized research centers and international health initiatives are key to advancing this field.

Effect of scanning strategies on the accuracy of digital intraoral scanners: a meta-analysis of in vitro studies.

PURPOSE: This study aimed to investigate whether the accuracy of intraoral scanners is influenced by different scanning strategies in an in vitro setting, through a systematic review and meta-analysis. MATERIALS AND METHODS: This review was conducted in accordance with the PRISMA 2020 standard. The following PICOS approach was used: population, tooth impressions; intervention, the use of intraoral scanners with scanning strategies different from the manufacturer's instructions; control, the use of intraoral scanners following the manufacturers' requirements; outcome, accuracy of intraoral scanners; type of studies, in vitro. A comprehensive literature search was conducted across various databases including Embase, SciELO, PubMed, Scopus, and Web of Science. The inclusion criteria were based on in vitro studies that reported the accuracy of digital impressions using intraoral scanners. Analysis was performed using Review Manager software (version 5.3.5; Cochrane Collaboration, Copenhagen, Denmark). Global comparisons were made using a standardized mean difference based on random-effect models, with a significance level of α = 0.05. RESULTS: The meta-analysis included 15 articles. Digital impression accuracy significantly improved under dry conditions (P < 0.001). Moreover, trueness and precision were enhanced when artificial landmarks were used (P ≤ 0.02) and when an S-shaped pattern was followed (P ≤ 0.01). However, the type of light used did not have a significant impact on the accuracy of the digital intraoral scanners (P ≥ 0.16). CONCLUSION: The accuracy of digital intraoral scanners can be enhanced by employing scanning processes using artificial landmarks and digital impressions under dry conditions.

LIGHT-CURED CALCIUM SILICATE BASED-CEMENTS AS PULP THERAPEUTIC AGENTS: A META-ANALYSIS OF CLINICAL STUDIES.

OBJECTIVES: To determine the clinical performance of light-cured calcium silicate-based cement for direct or indirect pulp capping. The research question was as follows: in teeth with deep caries lesions, does the use of resin-modified calcium silicate-containing composites improve the radiological success and prevent irreversible pulpitis and pulpal necrosis compared with other pulp-capping agents? MATERIALS AND METHODS: The following databases were screened until September 2021: PubMed, Web of Science, Scielo, Scopus, Embase, and The Cochrane Library. Randomized clinical trials reporting the clinical evaluation of a resin-modified calcium silicate material as an agent for pulp therapy were included. Meta-analysis was performed using the Rev Manager v5.4.1 software. The risk difference and 95% confidence interval of the dichotomous outcome (restoration failure or success) were calculated for comparison. RESULTS: Ten studies were considered for qualitative analysis and meta-analysis. Studies evaluating the performance of light-cured calcium silicate-based cement from 1 month to a maximum follow-up period of 36 months and comparing it with the performance of CaOH, mineral trioxide aggregate, or Biodentine were included. In the global analysis for direct pulp capping at 6-month follow-up, no statistical differences were observed between the experimental group using the light-cured calcium silicate-based cement and control group (P = .28). However, at 12-month follow-up, global analysis favored the control group (P < .001). For indirect pulp capping, at 6- and 24-month follow-ups, no statistically significant differences were observed between the experimental and control groups (P = .88; P = .21). CONCLUSIONS: Light-cured calcium silicate-based cement showed a limited clinical performance as a direct pulp capping agent, especially when evaluated in the long term. However, using it as an indirect pulp capping agent may be a reliable and easy-to-use option for restoring teeth with deep caries. CLINICAL SIGNIFICANCE: This systematic review provides evidence that supports the use of light-cured calcium silicate-based cement as an indirect pulp capping agent.

A Scoping Review on Use of Drugs Targeting the JAK/STAT Pathway in Psoriasis.

Introduction: The Janus kinase-signal transducer and activator of transcription (JAK/STAT) pathway are known to be involved in inflammatory immune-mediated skin diseases, including psoriasis. The development of drugs targeting the JAK/STAT signaling pathway presents new treatment opportunities for psoriasis. However, the application of JAK inhibitors for the treatment of dermatological disorders is still in its early stages of development. This review summarizes available evidence in an attempt to identify knowledge gaps for conducting further research studies and improving clinical decision-making. Objective: The objective of this study is to conduct a scoping review of the use of drugs targeting the JAK/STAT pathway in the treatment of psoriasis. Methods: A priori protocol for scoping review was published in 2019. The Joanna Briggs Institute Reviewer's Manual and the PRISMA Extension for Scoping Review were used for the review. MEDLINE, EMBASE, CINAHL, Scopus, and Web of Science databases and ClinicalTrials registry were referred to in April 2019 and March 2021, respectively. References in English involving evidence on the use of drugs targeting the JAK/STAT pathway in patients with psoriasis were included. Data charting was performed by two authors using tables and figures. Results: The evidence found on the efficacy and safety of drugs targeting the JAK/STAT pathway in patients with psoriasis comes from 118 articles reporting the results of 34 randomized clinical trials (RCTs). Nine different drugs administered through various routes were identified (systemic: peficitinib, baricitinib, solcitinib, itacitinib, abrocitinib, deucravacitinib, and brepocitinib; topical: ruxolitinib; and both: tofacitinib). Knowledge articles are mainly created and published by pharmaceutical companies and authors through their own funding or by those related to them. Only tofacitinib and deucravacitinib have undergone phase III clinical trials, being the only ones tested with active comparators etanercept and apremilast, respectively. Proportions of Psoriasis Area and Severity Index (PASI) and Physician's Global Assessment (PGA) were the efficacy variables most frequently studied in systemic treatments. Only two RCTs declared the safety data collected by systematic assessment; the only systemic drug with phase III data was tofacitinib. Tofacitinib 5 mg two times daily (BID)/10 mg BID efficacy was compared with etanercept 50 mg/week and a placebo. At 12-16 weeks, PASI 75/PGA 01 ranges were as follows: 38.07-80%/37.16-67.4% for tofacitinib 5 mg BID; 54.79-100%/50-75.6% for tofacitinib 10 mg BID; 58.8/66.8% for etanercept, date from one only study; and 0-33.3%/9.04-33.3% for the placebo group. Other drugs in earlier stages of development showed values within these ranges. The most frequent adverse events (AEs) were nasopharyngitis and upper respiratory tract infections in all treatment groups. Conclusion: There is increasing evidence on the use of drugs targeting the JAK/STAT pathway as a treatment for psoriasis, although they are in the early phases of development. The trials conducted to date have been financed directly or indirectly by the pharmaceutical industry, which must be taken into account when interpreting the results of the trials. Psoriasis treatment is currently symptomatic and could potentially present a significant risk of toxicity. Therefore, the design of principal efficacy outcome measures considering the impact of the outcome on quality of life and a drug assessment methodology aimed at improving safety would probably strengthen the evidence and decision-making process.

Methods: Retrospective, descriptive, longitudinal, comparative and analytical study. The results of the last 11 years of our service were analyzed by assessing the temperatures of the lesions by assembling two groups, 65° C-70° C and 71 ° C-75° C to analyze their relationship with results and complications. Results: 59 patients were treated in which 74 procedures were performed; the mean age was 59.22 years (± 13.45). Recurrence was observed in 23 procedures with an overall rate of 31%. The average recurrence time was 28.19 months (± 26.21). The average follow-up time was 33.10 months (± 33.49). The average time of pain evolution, prior to the first procedure, was 5.35 years (± 4.37). Analyzing the groups, it was observed that there was no significant statistical relationship (p = 0.74) between the group of patients from 65ºC-70ºC and the group from 71ºC-75ºC and recurrence. No statistically significant relationship was observed between the 65ºC-70ºC group and the 71ºC-75ºC group and recurrence time (p = 0.12). More patients with immediate hypoaesthesia were observed in the group of patients from 65ºC-70ºC, without statistical significance (p = 0.47). Conclusion: Gasser's ganglion radiofrequency thermocoagulation is an accessible, minimally invasive procedure that demonstrated good results and good pain management with a low complication rate

Acupuncture and moxibustion stimulate fibroblast proliferation and neoangiogenesis during tissue repair of experimental excisional injuries in adult female Wistar rats.

OBJECTIVE: To investigate the effects of acupuncture and moxibustion on the repair of excisional skin injuries on the back of adult female Wistar rats. METHODS: 90 animals were divided into three groups: C, control; A, acupuncture treatment (needled at traditional acupuncture points BL13, BL17 and ST36); M, moxibustion treatment (overlying same traditional acupuncture points). They were euthanased on days 7, 14 and 21 after injury for removal and preparation of tissue for analysis. RESULTS: The treated groups (A and M) showed no changes regarding the structural analysis relative to the control (C) group. The total number of fibroblast cells in the A and M groups were significantly higher than those in the C group on days 14 and 21. The number of granulocytes was significantly less in the A and M groups compared with the C group on days 14 and 21. The total number of newly formed vessels increased on day 21 and was significantly higher in the A and M groups. The amount of birefringent collagen fibre detected on day 21 was significantly higher in the C group. The amount of glycosaminoglycan and hydroxyproline was similar between the groups. The amount of collagen I did not differ between the groups in any period, despite the increased amount detected over time. The amount of type III collagen did not differ between the groups but the detected amount decreased over the course of the experiment. The amount of transforming growth factor ß1 (TGF-ß1) and vascular endothelial growth factor (VEGF) in the A and M rats was similar but inferior to C rats across all experimental periods. CONCLUSIONS: Acupuncture and moxibustion stimulated fibroblast proliferation and neoangiogenesis, and extended the period of collagen fibre reorganisation in the repair of excisional injuries in adult female rats.

Granuloma annulare skin profile shows activation of T-helper cell type 1, T-helper cell type 2, and Janus kinase pathways.

BACKGROUND: Granuloma annulare (GA) is an inflammatory skin disorder. Localized GA is often self-resolving, but generalized GA is often recalcitrant to treatments. There are no targeted treatments for GA, largely due to lack of mechanistic understanding. Recently, tumor necrosis factor antagonism showed promise in GA, suggesting an underlying immune pathogenesis. OBJECTIVE: To elucidate the immune pathogenesis and identify potential therapeutic targets for GA. METHODS: Lesional and nonlesional skin biopsy samples were obtained from patients with GA and evaluated for a large array of inflammatory markers compared with inflammatory markers from normal skin of healthy individuals. RESULTS: We found differential expression of many inflammatory genes compared with normal skin. These genes were associated with T-helper (Th) cell type 1/innate immunity (tumor necrosis factor-α, interleukin [IL]-1ß, IL-12/23p40, signal transducer and activator of transcription 1, chemokine [C-X-C motif] ligand 9/10), Janus kinase signaling, and Th2 (IL-4, IL-31, chemokine (C-C motif) ligands 17 and 18; P < .05). Unexpectedly, IL-4 showed significant upregulation in GA lesional skin vs control skin (15,600-fold change). LIMITATIONS: Limited sample size. CONCLUSIONS: Our findings shed light on the inflammatory pathways of GA, supporting the notion that immune mechanisms could be driving disease, as suggested by the promising data of tumor necrosis factor-α inhibitors in GA. The significant Janus kinase and particularly Th2 signaling in GA advocates for the investigation of specific Janus kinase- and Th2- targeted drug therapy.

Autism and Paediatric Dentistry: A Scoping Review.

PURPOSE: The objectives of this scoping review were: first, to pose a research question; second, to identify relevant studies to answer the research question; third, to select and retrieve the studies; fourth, to chart the critical data; and finally, to collate, summarise, and report the results from selected articles on the dental management of children affected with autism. MATERIALS AND METHODS: Relevant articles (randomised controlled trials, reviews, observational studies, and clinical case reports) published over an 11-year period were identified and retrieved from five internet databases: PubMed, Embase/Ovid, Cochrane Library, Google Scholar, and EBSCO. RESULTS: By title and abstract screening and after removing duplicates, 25 articles were finally included in the present scoping review. According to the extracted data, the following four clinical issues were found to be most important: patient behavioural control, prevalence/incidence of dental caries, adverse effects and interactions with medications, and orthodontic management. Additionally, several useful clinical recommendations are provided. CONCLUSIONS: Paediatric dentists should bear in mind that early diagnosis and treatment, effective communication skills, and a long-term follow-up of children with autism continue to be the best approaches for achieving enhanced patient psychological well-being and consequently a better quality of life.

Evolution of international collaborative research efforts to develop non-Cochrane systematic reviews.

This research-on-research study describes efforts to develop non-Cochrane systematic reviews (SRs) by analyzing demographical and time-course collaborations between international institutions using protocols registered in the International Prospective Register of Systematic Reviews (PROSPERO) or published in scientific journals. We have published an a priori protocol to develop this study. Protocols published in scientific journals were searched using the MEDLINE and Embase databases; the query terms "Systematic review" [Title] AND "protocol" [Title] were searched from February 2011 to December 2017. Protocols registered at PROSPERO during the same period were obtained by web scraping all non-Cochrane records with a Python script. After excluding protocols that had a fulfillment or duplication rate of less than 90%, they were classified as published "only in PROSPERO", "only in journals", or in "journals and PROSPERO". Results of data and metadata extraction using text mining processes were curated by two reviewers. These Datasets and R scripts are freely available to facilitate reproducibility. We obtained 20,814 protocols of non-Cochrane SRs. While "unique protocols" by reviewers' institutions from 60 countries were the most frequent, a median of 6 (2-150) institutions from 130 different countries were involved in the preparation of "collaborative protocols". The highest Ranked countries involved in overall protocol production were the UK, the U.S., Australia, Brazil, China, Canada, the Netherlands, Germany, and Italy. Most protocols were registered only in PROSPERO. However, the number of protocols published in scientific journals (924) or in both PROSPERO and journals (807) has increased over the last three years. Syst Rev and BMJ Open published more than half of the total protocols. While the more productive countries were involved in "unique" and "collaborative protocols", less productive countries only participated in "collaborative protocols" that were mainly published in PROSPERO. Our results suggest that, although most countries were involved in solitary production of protocols for non-Cochrane SRs during the study period, it would be useful to develop new strategies to promote international collaborations, especially with less productive countries.

Age-specific changes in the molecular phenotype of patients with moderate-to-severe atopic dermatitis.

BACKGROUND: Atopic dermatitis (AD) shows differential clinical presentation in older compared with younger patients. Nevertheless, changes in the AD molecular profile with age are unknown. OBJECTIVE: We sought to characterize age-related changes in the AD profile. METHODS: We evaluated age-specific changes in lesional and nonlesional tissues and blood from patients with moderate-to-severe AD (n = 246) and age-matched control subjects (n = 71) using immunohistochemistry, quantitative real-time PCR, and Singulex in a cross-sectional study. Patients were analyzed by age group (18-40, 41-60, and ≥61 years). RESULTS: Although disease severity/SCORAD scores were similar across AD age groups (mean, approximately 60 years; P = .873), dendritic cell infiltrates (CD1b+ and FcεRI+, P < .05) decreased with age. TH2 measures (IL5, IL13, CCL13, CCL18, and CCL26) significantly decreased with age in patients with AD, despite increasing with age in control subjects. Consistent with TH2 axis decreases, serum IgE levels and eosinophil counts negatively correlated with age in patients with AD (r = -0.24 and r = -0.23, respectively; P < .05). TH22-secreted IL22 expression levels also decreased with age uniquely in patients with AD (P < .05). Expression of TH1-related (IFNG, IL12/23p40, STAT1, and CXCL9; P < .05 for CXCL9) and TH17-related (IL17A and IL20; P < .05 for IL20) markers increased with age in both patients with AD and control subjects. Expression of terminal differentiation measures significantly increased in older patients with AD (loricrin [LOR] and filaggrin [FLG], P < .05), whereas expression of S100As (S100A8, P < .01) and hyperplasia markers (epidermal thickness, keratin 16, and Ki67; P < .05 for keratin 16) decreased. Serum trends in AD mimicked skin findings, with TH2 downregulation (CCL26; r = -0.32, P < .1) and TH1 upregulation (IFN-γ; r = 0.48, P < .01) with age. CONCLUSION: The adult AD profile varies with age. Although TH1/TH17 skewing increases in both patients with AD and control subjects, patients with AD show unique decreases in TH2/TH22 polarization and normalization of epithelial abnormalities. Thus age-specific treatment approaches might be beneficial for AD.
