RESUMO

BACKGROUND: Disparities in scholarship exist between authors in low- or middle-income countries (LMIC) and high-income countries. Recognizing these disparities in our global network providing pediatric, adolescent, and maternal healthcare to vulnerable populations in LMIC, we sought to improve access and provide resources to address educational needs and ultimately impact the broader scholarship disparity. METHODS: We created a virtual community of practice (CoP) program underpinned by principles from starling murmuration to promote interdisciplinary scholarship. We developed guiding principles- autonomy, mastery and purpose- to direct the Global Health Scholarship Community of Practice Program. Program components included a continuing professional development (CPD) program, an online platform and resource center, a symposium for scholarship showcase, and peer coaching. RESULTS: From February 2021 to October 2022, 277 individuals joined. Eighty-seven percent came from LMIC, with 69% from Africa, 6% from South America, and 13% from other LMIC regions. An average of 30 members attended each of the 21 CPD sessions. Thirty-nine authors submitted nine manuscripts for publication. The symposium increased participation of individuals from LMIC and enhanced scholarly skills and capacity. Early outcomes indicate that members learned, shared, and collaborated as scholars using the online platform. CONCLUSION: Sharing of knowledge and collaboration globally are feasible through a virtual CoP and offer a benchmark for future sustainable solutions in healthcare capacity building. We recommend such model and virtual platform to promote healthcare education and mentoring across disciplines.

RESUMO

Self-assembled enantiomers of an asymmetric di-iron metallohelix differ in their antiproliferative activities against HCT116 colon cancer cells such that the compound with Λ-helicity at the metals becomes more potent than the Δ compound with increasing exposure time. From concentration- and temperature-dependent 57Fe isotopic labelling studies of cellular accumulation we postulate that while the more potent Λ enantiomer undergoes carrier-mediated efflux, for Δ the process is principally equilibrative. Cell fractionation studies demonstrate that both enantiomers localise in a similar fashion; compound is observed mostly within the cytoskeleton and/or genomic DNA, with significant amounts also found in the nucleus and membrane, but with negligible concentration in the cytosol. Cell cycle analyses using flow cytometry reveal that the Δ enantiomer induces mild arrest in the G1 phase, while Λ causes a very large dose-dependent increase in the G2/M population at a concentration significantly below the relevant IC50. Correspondingly, G2-M checkpoint failure as a result of Λ-metallohelix binding to DNA is shown to be feasible by linear dichroism studies, which indicate, in contrast to the Δ compound, a quite specific mode of binding, probably in the major groove. Further, spindle assembly checkpoint (SAC) failure, which could also be responsible for the observed G2/M arrest, is established as a feasible mechanism for the Λ helix via drug combination (synergy) studies and the discovery of tubulin and actin inhibition. Here, while the Λ compound stabilizes F-actin and induces a distinct change in tubulin architecture of HCT116 cells, Δ promotes depolymerization and more subtle changes in microtubule and actin networks.

RESUMO

Purpose of Review: As the world grapples with the health systems' challenges during the COVID-19 pandemic, addressing the needs of the already vulnerable adolescents and young people is vital. This narrative synthesis is aimed to highlight the current gender, cultural, and socioeconomic dynamics fueling inequalities to accessing sexual, reproductive health and rights (SRHR) services among adolescents and young people in low- and middle-income countries (LMIC). Recent Findings: The COVID-19 pandemic has in most countries exacerbated already existing inequalities due to economic, gender, cultural, and legal aspects. Strategies implemented by most governments to mitigate the spread of the virus have also had a negative impact on the access to SRHR services, some of which are long term. Few published studies have assessed the extent to which the pandemic has fueled each of these paradigms regarding access to SRHR, especially among adolescents and young people (AYP). Additionally, there is paucity in data on the same in most countries, as the systems to track such effects were not available at the inception of the pandemic. Summary: Despite efforts to mitigate the effects of the pandemic on this population, deficits remain and a multi-stakeholder approach is needed to achieve the intended goals, especially where cultural and gender values are deeply rooted. Further research is needed to quantify how the pandemic has fueled economic, gender, and cultural aspects to influence access to SRHR services among AYP especially in LMIC.

RESUMO

INTRODUCTION: Obesity in adulthood is associated with reduced physical functioning (PF) at older ages. However, mechanisms underpinning this association are not well understood. We investigated whether and the extent to which C-reactive protein (CRP) mediates the association between early-adult obesity and mid-life PF. METHODS: We used data from 8495 participants in the 1958 British birth cohort study. Body mass index (BMI), CRP and PF were measured at 33, 45 and 50y, respectively. Poor PF was defined as the lowest (sex-specific) 10% on the Short-form 36 Physical Functioning subscale. We accounted for prospectively measured confounders in early-life (e.g., social class at birth) and in mid-adulthood (e.g., 42y comorbidities). We decomposed the total effect of early-adult obesity on mid-life PF into direct and indirect (via CRP) effects, by employing a mediation analysis based on parametric g-computation. RESULTS: The estimated total effect of obesity at 33y on poor PF at 50y, expressed as an odds ratio (OR), was 2.41 (95% CI: 1.89, 3.08). The direct effect of obesity on poor PF (i.e., not operating via CRP), was 1.97 (95% CI: 1.51, 2.56), with an indirect effect of 1.23 (95% CI: 1.10, 1.37). As such, the proportion of the total effect which was mediated by the effect of obesity on CRP at 45y, was 23.27% (95% CI: 8.64%, 37.90%). CONCLUSION: Obesity in early-adulthood was associated with over twice the odds of poor PF in mid-life, with approximately 23% of the obesity effect operating via a downstream effect on CRP. As current younger generations are likely to spend greater proportions of their life course in older age and with obesity, both of which are associated with poor PF, there is an urgent need to identify mechanisms, and thus potential modifiable intermediaries, linking obesity to poor PF.

RESUMO

This review forms part of a series of annual evidence updates on atopic eczema (AE), and provides a summary of key findings from systematic reviews (SRs) published or indexed in 2019 related to AE treatment. Several SRs assessed the efficacy of topical corticosteroids (TCS), topical calcineurin inhibitors, topical phosphodiesterase-4 inhibitors and topical Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway inhibitors. However, there is a lack of good-quality trials comparing topical treatment agents with TCS, which remain the standard of care for patients with AE. Most of the included trials lack meaningful comparisons as they used vehicle as a comparator. There is also lack of harmonization of outcome measures for AE across studies. Large, well-designed RCTs are needed to further determine whether any specific emollients offer superior benefit. There is evidence highlighting limited benefit of oral H1 antihistamines as 'add-on' therapy to topical treatment of eczema. Mycophenolate mofetil may have a role in patients with refractory AE. Among biologic therapies, most of the efficacy data relate to dupilumab. Furthermore, there is growing evidence for the efficacy and safety of systemic JAK/STAT pathway inhibitors, but the existing data are of low quality.

RESUMO

This review is part of an annual evidence update on atopic eczema (AE), providing a summary of key findings from 18 systematic reviews published in 2019 on AE risk factors and prevention. Parental atopy, particularly AE, is a risk factor for offspring AE, and this risk is augmented both by the number of parental atopic diseases present and the number of affected parents. Low-quality evidence suggests that autumn or winter birth increases childhood AE risk compared with birth in spring. There is some evidence to support filaggrin gene-environment interactions; however, this is limited by small underpowered studies. There is no evidence to suggest that polymorphisms in the -1082, -592 and -819 loci of the interleukin-10 gene increase susceptibility to AE. There is no robust evidence to support a relationship between childhood AE development and either yoghurt consumption in the first year of life, gut microbiota variants, prenatal or infantile paracetamol exposure, maternal antibiotic exposure or air pollution. Three systematic reviews investigated the effect of probiotics given during pregnancy or infancy; although low-quality evidence suggests benefits of combined probiotics, these studies were limited by significant heterogeneity. No relationship between the age at which complementary food and beverages are introduced and the risk of developing AE in infancy was identified. Consistent evidence showed no relationship between human milk feeding and infant AE development, aside from limited evidence suggesting a protective role in those with atopic heredity. This summary of recent evidence related to AE risk factors and prevention highlights the complex aetiology of AE.

RESUMO

Atopic eczema (herein referred to as 'eczema') is a skin disease characterized by remitting and relapsing symptoms. The Harmonising Outcome Measures for Eczema (HOME) initiative was developed to establish a core outcome set (COS) for eczema to be measured for all future eczema trials. The core outcome set for atopic eczema clinical trials includes the domain for patient-reported eczema control, but a review of the validation of available eczema control instruments was lacking. We aimed to review the literature and systematically assess the measurement properties of validated patient-reported outcome instruments that capture eczema control. PubMed and Ovid EMBASE were searched up to 24 January 2020 for any study that reported on PROM instrument development or validation. The COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) criteria were used to assess the quality of eligible studies. We screened 12 036 titles and abstracts and 58 full texts. A total of 12 papers were included, reporting on seven PROMS. These were assessed with respect to development, reliability, construct validity and responsiveness. Two instruments, Recap of Atopic Eczema (RECAP) and the Atopic Dermatitis Control Tool (ADCT), have been developed and validated to a sufficient standard to support their recommendation as patient-reported outcome instruments for measuring control of atopic eczema as part of the HOME Core Outcome Set.

RESUMO

BACKGROUND: Standardized outcome reporting is crucial for trial evidence synthesis and translation of findings into clinical decision-making. The OMERACT 2.0 Filter and COMET outcome domain taxonomy propose frameworks for consistent reporting of outcomes. There is an absence of a uniform dermatology-specific reporting strategy that uses precise and consistent outcome definitions. OBJECTIVES: Our aim was to map efficacy/effectiveness outcomes assessed in dermatological trials to the OMERACT 2.0 Filter as a starting point for developing an outcome taxonomy in dermatology. METHODS: We critically appraised 10 Cochrane Skin Reviews randomly selected from all 69 Cochrane Skin Reviews published until 01/2015 and the 220 trials included covering a broad spectrum of dermatological conditions and interventions. Efficacy/effectiveness outcomes were mapped to core areas and domains according to the OMERACT 2.0 Filter. The extracted trial outcomes were used for critical appraisal of outcome reporting in dermatology trials and for the preliminary development of a dermatology-specific outcome taxonomy. RESULTS: The allocation of 1086 extracted efficacy/effectiveness outcomes to the OMERACT 2.0 Filter resulted in a hierarchically structured dermatology-specific outcome classification. In 506 outcomes (47%), the outcome concept to be measured was insufficiently described, hindering meaningful evidence synthesis. Although the core areas assessed in different dermatology trials of the same condition overlap considerably, quantitative evidence synthesis usually failed due to imprecise outcome definitions, non-comparable outcome measurement instruments, metrics and reporting. CONCLUSIONS: We present an efficacy/effectiveness outcome classification as a starting point for a dermatology-specific taxonomy to provide trialists and reviewers with the opportunity to better synthesize and compare evidence.

RESUMO

BACKGROUND: Research impact describes whether and how research results in wider benefits to society beyond academic publication. Little is known about translation of clinical trial research into dermatological practice. AIM: We scoped international impact from four independently funded clinical trials published by our group over the past 10 years. METHODS: This was a scoping survey of 35 international colleagues from 22 countries followed by a narrative summary of emergent themes. RESULTS: All recipients kindly responded to the survey. At least 20 emergent themes were identified, which broadly included: (i) interest and enthusiasm in the concept of trying to document clinical trial impact; (ii) direct impacts such as adoption of the drug as tested and recommended from the trial results, including more confidence using the drug in slightly different ways for the same condition; (iii) the finding that trial impact was dependent on factors such as drug availability and country-specific disease patterns; and (iv) the educational value of good trial design for journal club discussions and improving future clinical trial designs in dermatology. Our survey suggests that uptake into clinical practice was surprisingly rapid and widespread. CONCLUSION: Clinical trial research is of little use unless findings are translated into clinical practice for patient benefit. Our international scoping survey suggests that independent clinical trials that address important questions identified by the dermatology community have substantial, diverse and far-reaching impacts on dermatological practice.

RESUMO

This review is part of a series of annual updates that summarize the evidence base for atopic eczema (AE). The aim is to provide a succinct guide for clinicians on the key findings from 14 systematic reviews on the prevention and topical treatment of AE published or indexed in 2018. Various supplements, including long-chain polyunsaturated fatty acids, vitamin D and the probiotic Lactobacillus rhamnosus GG, given prenatally and postnatally, have not been shown to prevent AE in infants, although mixed strains of probiotics may decrease the risk of AE if given to the mother during pregnancy and to the infant for the first 6 months of life. In the postnatal period, there is no evidence that hydrolysed formula, compared with cow's milk formula (CMF), reduces the risk of AE in partially breastfed infants. However, weak evidence suggests that a specific partially hydrolysed whey formula decreases the risk of AE compared with CMF. No specific skin practices can be recommended to reduce the eczema risk in healthy term babies. There is weak evidence of a low risk of reversible hypothalamic-pituitary-adrenal axis suppression following 2-4 weeks of treatment with low-potency topical steroids, and conflicting evidence as to whether bleach bathing affects skin flora or AE severity. A single study demonstrated that the topical Janus kinase inhibitor tofacitinib at 2% significantly reduces the Eczema Area and Severity Index compared with vehicle. Topical naltrexone cream 1% improves pruritus (measured using a visual analogue scale) by 30% more than placebo. There is weak evidence that topical alternative therapies, including antioxidants, micronutrients and some herbal medicines, may improve AE.

RESUMO

This review forms part of an annual update series on atopic eczema (AE), where systematic reviews (SRs) are gathered and appraised to provide a summary of key recent research findings. The focus of this article is systemic therapies used in AE, while a review on prevention and topical therapies is provided in Part 1. In total, 17 SRs on various systemic treatments used in AE were first published or indexed in 2018. There is a lack of evidence to support vitamin D supplementation, montelukast and naltrexone in AE treatment. The adverse effects of systemic corticosteroids are the main barrier to their use, and there is also a lack of data to determine the optimal delivery and duration of treatment with them. Of other immunosuppressants, ciclosporin has the most robust evidence of efficacy. Biologic therapies in AE treatment are being increasingly investigated, and to date, the greatest quantity of data and evidence of efficacy relates to dupilumab. The most commonly reported adverse effects are injection-site reactions and conjunctivitis. Other biologics showing some evidence of efficacy include nemolizumab, lebrikizumab and tralokinumab, although further data are needed. There are currently insufficient data on oral small molecules, including Janus kinase inhibitors, in the treatment of AE. A Cochrane review on probiotics showed no significant benefit, and SRs and meta-analyses on complementary and alternative medicines, including probiotics, in paediatric AE demonstrated significant heterogeneity, thereby limiting their interpretation. This summary of recent SRs provides up-to-date evidence for clinicians on systemic therapies in AE.

RESUMO

BACKGROUND: Eczema control has been identified as an important outcome by key stakeholders in eczema research (including patients, carers, healthcare professionals and researchers) but no validated instruments for the domain have been identified. OBJECTIVES: To develop a measurement instrument to capture a patient's perspective of eczema control that is suitable for use in eczema clinical trials. METHODS: Best practice for the development of a patient-reported outcome was followed. A mixed-methods approach was used to develop and refine a conceptual framework, generate, refine and select items and to test the distribution and construct validity of the final scale. The mixed-methods approach involved expert panel meetings (including patient representatives, healthcare professionals and methodologists), and data collection using a focus group, cognitive interviews and an online survey with people with eczema and caregivers. Multivariable linear regression was used in the item selection process. RESULTS: Fourteen expert panel members co-produced the instrument, with input from people with eczema and caregivers via a focus group (n = 6), cognitive interviews (n = 13) and an online survey (n = 330). The resulting instrument, Recap of atopic eczema (RECAP), is a seven-item questionnaire that captures eczema control via self or caregiver report. The development process aimed to ensure good content validity and feasibility. Initial testing suggested no floor or ceiling effects and good construct validity. Hypothesized correlation with the Patient-Oriented Eczema Measure was confirmed [r(258) = 0·83, P < 0·001]. CONCLUSIONS: RECAP has the potential to improve reporting of eczema control in research and clinical practice. Further exploration of measurement properties is required. Linked Comment: Pattinson and Bundy. Br J Dermatol 2020; 183:418-419. What's already known about this topic? Eczema control has been identified as an important outcome by key stakeholders in eczema research (including patients, carers, healthcare professionals and researchers). Qualitative studies suggest eczema control is a multifaceted and individual experience and no instrument has been identified that captures eczema control in this way. What does this study add? We have developed Recap of atopic eczema (RECAP), a seven-item questionnaire to capture the experience of eczema control in all ages and eczema severities; there are two versions: a self-reported version for adults and older children with eczema, and a caregiver-reported version for younger children with eczema. Designed with input from people with eczema, caregivers and healthcare professionals to ensure good content validity. Initial testing of score distributions and construct validity suggests good measurement properties. What are the clinical implications of the work? The RECAP instrument is appropriate and feasible for measuring eczema control in clinical trials and may also be useful in routine practice.

RESUMO

This article forms part of a series of annual updates that summarizes the evidence base for atopic eczema (AE). It provides a summary of key findings from 28 systematic reviews that were published or indexed during 2017, and focuses on the epidemiology, aetiology and risk factors of AE. AE is the largest single contributor to morbidity associated with skin disease worldwide, once mortality has been excluded. There is a high prevalence of sleep disturbance in individuals with AE and they take more sick leave than controls. While there is a lack of skin bacterial diversity in patients with AE, there is a relative abundance of Staphylococcus aureus and Staphylococcus epidermidis. Compared with controls, affected individuals more often show an IgE response to S. aureus antigens and have higher serum interleukin-31 levels. Early antibiotic exposure, environmental pollutants, maternal atopy and food allergy are associated with an increased risk of AE, and very preterm birth is associated with decreased risk. Patients with AE have a reduced risk of meningioma, but are more likely to develop attention-deficit hyperactivity disorder compared with controls. Patients with eosinophilic oesophagitis are significantly more likely than unaffected individuals to have AE. There is no significant overall association between AE and allergic contact dermatitis (ACD), and in children referred for patch testing, ACD was more common in those without AE. Hand eczema is more prevalent in patients with AE. There is no association between AE and Type 2 diabetes, hypertension, stroke or myocardial infarction.

RESUMO

This review forms part of a series of annual updates that summarize the evidence base for atopic eczema (AE). It provides a summary of key findings from 25 systematic reviews that were published or indexed during 2017, and focuses on the treatment and prevention of AE. There is high-quality evidence to demonstrate that dupilumab is better than placebo for the treatment of AE, is not associated with a higher incidence of adverse effects and does not increase the risk of infection compared with placebo; however, comparison studies with other systemic treatments are necessary. Topical tofacitinib is a promising treatment for mild-moderate AE, but currently lacks sufficient evidence from well-designed randomized controlled trials (RCTs) comparing with other active treatments. Topical doxepin may be effective for pruritus in AE, but available studies have short follow-up periods and longer-term outcomes are needed. Bleach baths were no more effective than water baths alone at reducing AE severity. Topical antibiotics cannot be recommended for infected AE, owing to insufficient evidence of benefit. There is little comparison of different emollients in RCTs, but overall evidence indicates that they reduce AE severity, are steroid-sparing and lead to better outcomes in combination with topical corticosteroids (TCS) than TCS alone. No clear benefit was demonstrated for vitamin D/C/E supplementation in pregnancy for eczema prevention.

RESUMO

BACKGROUND: Adolescent sexual risky behaviours continue to be significant drivers of the HIV epidemic globally. The objective of this study was to determine factors associated with prior engagement in high-risk sexual behaviours among adolescents (10-19 years) in Karamoja sub-region, a pastoralist and post-conflict community in North-eastern Uganda. METHODS: Between August and September 2016, we conducted a cross-sectional study among 1439 adolescents receiving primary healthcare services at nine public health facilities located in five of the seven districts that make up Karamoja sub-region. High-risk sexual behaviour was defined as engaging in sex with two or more (2+) sexual partners in the 6 months preceding the survey or exchanging sex for money or gifts with no or inconsistent use of condoms over the same period of time. Factors associated with prior engagement in high-risk sexual behaviours were analysed using a modified Poison regression model with log-link and Poisson-family via a generalized linear model. RESULTS: Eighty-two percent (81.8%, n = 1177) of the respondents had ever tested for HIV while 62 % (61.5%, n = 885) had ever had sex. Of those that had ever had sex, 11.4% (n = 101) reported prior engagement in high-risk sexual behaviours. Prior engagement in high-risk sexual behaviours was lower among men than women (adjusted prevalence ratio (adj. PR) = 0.46; 95% Confidence Interval (95% CI): 0.33, 0.62) and those whose sex debut was above 14 years (adj.PR = 0.63; 95% CI: 0.57, 0.69). However, prior engagement in high-risk sexual behaviours was significantly higher in adolescents who were not aware of their recent sexual partner's HIV status (adj.PR = 2.43; 95% CI: 1.68, 3.52) and those who used illicit drugs (adj.PR = 2.76; 95% CI: 1.88, 4.05). CONCLUSION: Prior engagement in high-risk sexual behaviours was significantly associated with having sex with partners of unknown HIV sero-status and use of illicit drugs. These findings suggest a need for targeted interventions to improve mutual HIV status disclosure between sexual partners while minimizing their use of illicit drugs/substances.

RESUMO

It is common practice to perform pre-operative coagulation screening in elective neurosurgery patients, including international normalised ratio (INR) and activated partial thromboplastin time (aPTT). We present a retrospective analysis of 1143 elective neurosurgical patients at Wellington Regional Hospital (WRH) in New Zealand between 2013 and 2017 on whom coagulation screening including INR and aPTT was performed prior to surgery. 21 patients (1.8%) had clinically significant derangements on coagulation profile defined as raised INR or prolonged aPTT. 15 (1.3%) of these patients would be expected to have derangement based on previous history and 6 (0.5%) had unexpected derangements in coagulation profile. Of the 6 patients with unexpected derangements in coagulation profile, all had raised aPTT, none had preoperative correction of coagulopathy and none had bleeding complications or mortality. The cost of coagulation screening across the duration of the study was $68,009 New Zealand Dollars (NZD). A survey of major elective neurosurgery units in Australia and New Zealand found that 85% perform routine laboratory coagulation screening. In the 15% who do not perform laboratory coagulation screening, none use a standardised questionnaire to screen for coagulopathy. We developed a structured questionnaire to assist in detection of coagulopathy in elective neurosurgery patients. Our findings suggest that there is limited value in performing indiscriminate laboratory coagulation screening in patients with no risk factors on history. Despite this, routine laboratory coagulation screening is common practice in Australia and New Zealand. We propose a structured questionnaire to guide laboratory testing and discussions with haematology colleagues.

RESUMO

This review forms part of a series of annual updates that summarize the evidence base for atopic eczema (AE), providing a succinct guide for clinicians and patients. It presents the key findings from 14 systematic reviews published in 2016, focusing on AE epidemiology, aetiology and risk factors. For systematic reviews on the treatment and prevention of AE and for nomenclature and outcome assessments, see Parts 1 and 3 of this update, respectively. The annual self-reported prevalence of AE is a range of 11.4-24.2%, compared with a general practioner-diagnosed prevalence of 1.8-9.5%. The mean age of AE diagnosis is 1.6 years. Persistent AE is associated with more severe disease at the time of diagnosis, onset after the age of 2 years and female sex. There is a significant association between having AE and subsequent development of food allergy. Food allergy is also associated with more severe and persistent AE. No consistent association was found between the timing of allergenic food introduction and the risk of developing AE. Evidence from heterogeneous studies indicates that skin absorption is increased in patients with AE, and that there is increased colonization with Staphylococcus aureus in lesional and nonlesional skin and the nasal mucosa of patients with AE compared with controls. There is uncertain evidence indicating an association between AE and smoking exposure, antenatal infection and low maternal vitamin D levels during pregnancy. Weak evidence suggests an increased risk of basal cell carcinoma, but not of melanoma or squamous cell carcinoma, while the risk of glioma is reduced.

RESUMO

This review forms part of a series of annual updates that summarize the evidence base for atopic eczema (AE). It presents the key findings from 11 systematic reviews published in 2016 that focus on AE outcome assessment, disease impact and nomenclature. Systematic reviews on the treatment and prevention of AE are summarized in Part 1 of this update, and systematic reviews on the epidemiology of and risk factors for AE are summarized in Part 2. Six reviews summarized what outcome measurement instruments have been used in published AE trials, or summarized validation studies for the available instruments. These reviews were used to inform consensus decisions by the Harmonising Outcome Measures for Eczema initiative. Although validated instruments exist for clinical signs and patient-reported symptoms, there are currently no validated instruments for capturing quality of life or long-term control. Four reviews examined the impact of AE on children and their families, but few studies were included. One birth cohort study found no association between AE and educational attainment at 11 years. AE has a moderate impact on health-related quality of life and a substantial impact on family life. AE is a major risk factor for occupational hand dermatitis, and it is advised that young atopic individuals are informed about high-risk occupations. Further efforts are required to standardize the nomenclature for AE, which is also commonly known as 'atopic dermatitis' or 'eczema', and preferred terms vary around the world.

RESUMO

This review is part of a series of annual updates summarizing the evidence base for atopic eczema (AE). It provides a summary of key findings from 28 systematic reviews that were published or indexed during 2016 with a focus on treatment and prevention of AE. There is reasonable evidence of benefit for topical corticosteroids, calcineurin inhibitors, a glycyrrhetinic acid-containing preparation (Atopiclair® ), oral ciclosporin, oral azathioprine, narrowband ultraviolet B radiation and education programmes. Overall, there is evidence that topical corticosteroids and calcineurin inhibitors have similar efficacy and that both can prevent AE flares when used twice weekly as maintenance therapy. However, topical calcineurin inhibitors are costlier and have more adverse reactions, thus topical corticosteroids should remain the standard of care for patients with AE. There is no evidence that multiple applications are better than once-daily application of topical corticosteroid. There is inconsistent evidence to support omalizumab and specific allergen immunotherapy use in AE. There is some evidence that vitamin D supplementation and synbiotics reduce AE severity, although the margin of improvement may not be clinically meaningful. There is little evidence to support the use of wet wraps or of complementary/alternative medicine (including Chinese herbal medicine). There is some evidence to suggest that a diet high in fish in infancy may be preventative for AE, but other dietary interventions for the prevention of AE show little promise. This review provides a succinct guide for clinicians and patients wishing to remain up to date with the latest evidence for the treatment and prevention of AE.
