RESUMO

BACKGROUND: Allergy to peanuts and tree nuts is a common cause of food allergy in Spain, with lipid transfer proteins (LTP) being the most frequently recognized panallergen. LTP sensitization often leads to multiple food group sensitivities, resulting in overly restrictive diets that hinder patient's quality of life. This study aimed to assess the tolerance of peanuts and tree nuts (hazelnuts and walnuts) in children sensitized to LTP, potentially mitigating the need for such diets. METHODS: This prospective study enrolled individuals diagnosed with allergy to peanuts, hazelnuts, or walnuts. Data were collected from medical records, including demographics and clinical history. Allergological assessment comprised skin prick tests using commercial extracts and the nuts in question, alongside measurements of total and specific IgE to nuts and their primary molecular components. Participants showing positive LTP sensitization without sensitization to seed storage proteins underwent open oral nut challenges. RESULTS: A total of 75 individuals labeled as allergic to peanuts, 44 to hazelnuts, and 51 to walnuts were included. All of them underwent an open oral provocation test with the incriminated nut, showing a high tolerance rate. Peanut was tolerated by 98.6% of patients, 97.72% tolerated hazelnut, and 84.3% tolerated walnut. CONCLUSION: The findings suggest that the majority of patients allergic to peanuts, hazelnuts, or walnuts, due to LTP sensitization and lacking IgE reactivity to seed storage proteins, can tolerate these nuts. This supports the need for personalized nut tolerance assessments to avoid unnecessary dietary restrictions.

RESUMO

Language discordance between clinicians and families in pediatrics has been associated with adverse events and lower quality of care. We aimed to summarize the existing literature evaluating the impact of language discordance among healthcare professionals and families within pediatric oncology by conducting a systematic review. Of 8364 studies, 43 studies met eligibility for inclusion in this review. These studies highlight the impact of language discordance on pediatric cancer care outcomes, including communication challenges, obstacles to research participation, and potentially higher risk disease features at presentation. Healthcare professionals endorsed inconsistent professional interpreter use and lack of formal training on communicating via interpreters. Interventions to address barriers to language-appropriate care are sparse. Further research is warranted to design and implement interventions promoting language justice and provision of high-quality, equitable pediatric cancer care for all families.

RESUMO

The interplay between three-dimensional chromosome organisation and genomic processes such as replication and transcription necessitates in vivo studies of chromosome dynamics. Fluorescent organic dyes are often used for chromosome labelling in vivo. The mode of binding of these dyes to DNA cause its distortion, elongation, and partial unwinding. The structural changes induce DNA damage and interfere with the binding dynamics of chromatin-associated proteins, consequently perturbing gene expression, genome replication, and cell cycle progression. We have developed a minimally-perturbing, genetically encoded fluorescent DNA label consisting of a (photo-switchable) fluorescent protein fused to the DNA-binding domain of H-NS - a bacterial nucleoid-associated protein. We show that this DNA label, abbreviated as HI-NESS (H-NS-based indicator for nucleic acid stainings), is minimally-perturbing to genomic processes and labels chromosomes in eukaryotic cells in culture, and in zebrafish embryos with preferential binding to AT-rich chromatin.

RESUMO

Salmonella hijack host machinery in order to invade cells and establish infection. While considerable work has described the role of host proteins in invasion, much less is known regarding how natural variation in these invasion-associated host proteins affects Salmonella pathogenesis. Here we leveraged a candidate cellular GWAS screen to identify natural genetic variation in the ARHGEF26 (Rho Guanine Nucleotide Exchange Factor 26) gene that renders lymphoblastoid cells susceptible to Salmonella Typhi and Typhimurium invasion. Experimental follow-up redefined ARHGEF26's role in Salmonella epithelial cell infection. Specifically, we identified complex serovar-by-host interactions whereby ARHGEF26 stimulation of S. Typhi and S. Typhimurium invasion into host cells varied in magnitude and effector-dependence based on host cell type. While ARHGEF26 regulated SopB- and SopE-mediated S. Typhi (but not S. Typhimurium) infection of HeLa cells, the largest effect of ARHGEF26 was observed with S. Typhimurium in polarized MDCK cells through a SopB- and SopE2-independent mechanism. In both cell types, knockdown of the ARHGEF26-associated protein DLG1 resulted in a similar phenotype and serovar specificity. Importantly, we show that ARHGEF26 plays a critical role in S. Typhimurium pathogenesis by contributing to bacterial burden in the enteric fever murine model, as well as inflammation in the colitis infection model. In the enteric fever model, SopB and SopE2 are required for the effects of Arhgef26 deletion on bacterial burden, and the impact of sopB and sopE2 deletion in turn required ARHGEF26. In contrast, SopB and SopE2 were not required for the impacts of Arhgef26 deletion on colitis. A role for ARHGEF26 on inflammation was also seen in cells, as knockdown reduced IL-8 production in HeLa cells. Together, these data reveal pleiotropic roles for ARHGEF26 during infection and highlight that many of the interactions that occur during infection that are thought to be well understood likely have underappreciated complexity.

RESUMO

PURPOSE: Lenalidomide remains an effective drug for multiple myeloma, but it is often associated with adverse events and requires dose adjustments. The objective of this study was to propose a model for predicting whether a patient would require dose adjustment. METHODS: This retrospective observational study included patients treated with lenalidomide and dexamethasone from June 2014 to September 2018 at a tertiary hospital. Demographic variables, patient functional status, disease, analytical data specific to myeloma, and treatment-related variables were collected. Univariate and machine learning (logistic regression and classification and regression trees model) analyses were also performed. Kaplan-Meier analysis was used to determine the time of toxicity onset. Only lenalidomide (and not dexamethasone) related dose reductions are included. RESULTS: A total of 64 patients received lenalidomide-dexamethasone. 69% (44) required dose reduction or discontinuation of treatment due to lenalidomide-related adverse events. The median time between treatment beginning and lenalidomide dose reduction or discontinuation was 8.0 months (95% CI: 6.0-17.0). Age, platelet count, and neutrophil count were related to dose reduction in the univariate model. In the multivariate models, age and neutrophil count were significant in the logistic regression model, renal clearance, and neutrophil count in the classification and regression trees model. CONCLUSION: Elderly patients and those with low bone marrow reserves are prone to dose-limiting adverse events. This study can aid in making follow-up, prophylaxis, and dosing decisions to achieve better pharmacotherapeutic results.

RESUMO

Melasma is a common circumscribed hypermelanosis of sun-exposed areas of the skin. Platelet-Rich Plasma therapy has been evidenced to inhibit melanin synthesis in animals and humans. To determine the effectiveness of platelet-rich plasma as a treatment for melasma. Twenty female patient with melasma were involved in this study. The intervention included three Platelet-Rich Plasma application sessions at 15-day intervals. Patients were evaluated before and after treatment. Variables measured included the facial melanin concentration using the melasma area and severity index score, melasma quality of life scale satisfaction grade, and histologic changes. Mean age was 41 ± 7 years. An initial MELASQOL score of 42 ± 14.8 and final score of 16.6 ± 7.2 (p = 0.008) were reported; the initial and final MASI score were 15.5 ± 8.4 and 9.5 ± 7.2 (p = 0.001), respectively. The dermatoscopy examination revealed a decrease in pigmentation after intervention (p = 0.001). Histopathologic improvement was detected in reductions in cutaneous atrophy (14 [70%] vs. 11 [55%]), solar elastosis (15 [75%] vs.11 [55%]), and inflammatory infiltrate (9 [45%] vs. 6 [30%]), before and after treatment, respectively. The intervention was associated with decreased intensity of the melasma patch and improved skin quality, shown by the MELASQOL and MASI scores.

RESUMO

The first atmospheric PAHs levels and associated inhalation cancer risk were assessed over southwest Buenos Aires region by deploying PUF disk PAS samplers. Eight sampling location included coastal zones, touristic beaches, and rural inland areas were considered. PUF disks were fortified with surrogate standards and extracted by automated Soxhlet prior to GC-MS analysis. Σ16 PAHs ranged from 1.13 to 44.5 ng m-3 (10.3 ± 9.8), while urban locations showed up to 10 times higher PAH levels than rural or beach locations. Direct sources of PAHs, such as intensive vehicle traffic, heating, and general combustion activities, were identified. PAHs with four to six rings (46.62%) were predominantly Flt, Pyr, BbF, and BkF, and carcinogenic risk was expressed by BaP (0.10 ± 0.07 ng m-3) and BaPTEQs (0.26 ± 0.22 ng m-3). Inhalation ECR (2.23E-5, WHO) presented the lowest risk at beach locations. Molecular ratios and PCA showed a strong dominance in pyrolytic sources, such as biomass and coal combustion, with a particular signature in fires at inland locations. Overall, this study demonstrated that PUF disk passive air sampling provided a sound and simple approach for tracking air PAHs, their sources and public health risks, bringing a cost-effective tool for pollution control measures, even at small and remote towns. This is particularly relevant in extensive countries with medium or low income, such as Argentina.

RESUMO

BACKGROUND: Previously selected lamivudine resistance-associated mutations (RAMs) may remain archived within the proviral HIV-DNA. OBJECTIVES: To evaluate the ability of proviral DNA genotyping to detect lamivudine RAMs in HIV-1 virologically suppressed participants; the correlation between Sanger and next generation sequencing (NGS); and predictive factors for detection of lamivudine RAMs in proviral DNA. METHODS: Cross-sectional study of participants on stable antiretroviral therapy and suppressed for ≥1 year. Analysis of proviral DNA was performed by Sanger sequencing in whole blood and by NGS in PBMCs. RESULTS: We analysed samples from 102 subjects (52 with and 50 without lamivudine RAMs in historical plasma RNA-genotypes). Among participants with previous lamivudine resistance, Sanger sequencing detected RAMs in 26.9%. Detection rates significantly increased using NGS: 47.9%, 64.6%, 75% and 87.5% with the 20%, 10%, 5% and 1% thresholds, respectively. As for participants without historical lamivudine resistance, Sanger detected the RAMs in 1/49 (2%), and NGS (5% threshold) in 8/45 (17.8%). Multivariate models fitted to the whole population revealed that having a history of lamivudine resistance was a risk factor for detection of lamivudine RAMs by NGS. Among participants with historical lamivudine resistance, multivariate analysis showed that a longer time since HIV diagnosis was associated with persistence of archived mutations by NGS at thresholds of >10% [OR 1.10 (95% CI: 1.00-1.24)] and >5% [OR 1.16 (95% CI: 1.02-1.32)]. CONCLUSIONS: Proviral DNA Sanger sequencing does not detect the majority of historical lamivudine RAMs. NGS increases the sensitivity of detection at lower thresholds, although the relevance of these minority populations with lamivudine RAMs needs further evaluation.

RESUMO

BACKGROUND: In the ART-PRO pilot trial there were no virological failures through 48 weeks of treatment with dolutegravir plus lamivudine in suppressed individuals with and without archived lamivudine resistance-associated mutations (RAMs) detected through next-generation sequencing (NGS) but without evidence of lamivudine RAMs in baseline proviral DNA population sequencing. OBJECTIVES: To present 96 week results from ART-PRO. METHODS: Open-label, single-arm pilot trial. At baseline, all participants switched to dolutegravir plus lamivudine. Participants were excluded if proviral DNA population genotyping detected lamivudine RAMs. To detect resistance minority variants, proviral DNA NGS was retrospectively performed from baseline samples. For this analysis the efficacy endpoint was the proportion of participants with <50 HIV-1 RNA copies/mL at week 96. Safety and tolerability outcomes were incidence of adverse events and treatment discontinuations. RESULTS: Forty-one participants were included, 21 with lamivudine RAMs in historical plasma RNA genotypes. Baseline proviral DNA NGS detected lamivudine RAMs (M184V/I and/or K65R/E/N) above a 5% threshold in 71.4% (15/21) and 15% (3/20) of participants with and without history of lamivudine resistance, respectively. At 96 weeks, 90.2% of participants achieved the efficacy endpoint. Between week 48 and 96 there was one discontinuation due to consent withdrawal and no discontinuations related to adverse events. Two participants had a transient viral rebound, both re-suppressed on dolutegravir plus lamivudine. Through week 96, there were no virological failures. CONCLUSIONS: In this pilot trial, dolutegravir plus lamivudine maintained virological suppression at 96 weeks despite historical lamivudine resistance and persisting archived minority lamivudine RAMs.

RESUMO

This study evaluates for the first time the distribution and accumulation of butyltin compounds (BTs) in different compartments such as seawater, sediments, suspended particulate matter (SPM), and mussels (Brachidontes rodriguezii) in the Bahía Blanca estuary. The samples were collected from six sampling sites with different anthropogenic impacts. A better visualization and interpretation of data was achieved using chemometric tools (Tucker4 model), which made it possible to reveal the main relationships among the variables. This analysis showed the presence of BTs in all the estuarine environmental compartments, even in sites with low human intervention. The relationships found among BTs levels, seasons, and environmental matrices show the importance of biological processes such as phytoplankton blooms and remobilization of sediments (by tidal dynamics and/or periodic dredging) in BTs distribution and degradation. In addition, partition coefficients showed that mussels mainly bioaccumulate tributyltin from sediment, water and, to a lesser extent, SPM.

RESUMO

Grazing in small-scale dairy systems reduces costs and enhances sustainability. However, binary pastures (BP) have low persistency, which may be increased by including more species given their flexibility to withstand different agroecological and management situations. The objective was to assess a multi-species (MS) pasture of perennial ryegrass (RG), tall fescue (TF), bromegrass (BG), red clover (RC) and white clover (WC) in comparison to a BP of perennial ryegrass (RG) - WC grazed by six Holstein dairy cows during the dry season in an on-farm double cross-over experiment, with three 14-day each experimental periods for animal variables, and a split-plot design for pasture variables at 3 cow/ha. There were differences (P < 0.05) between pastures for sward height (MS 5.0 vs. BP 4.0 ± 0.10 cm, both MS and BP) and net herbage accumulation (MS 902 vs BP 228 ± 172.4 kg DM/ha, both MS and BP) and differences (P < 0.05) for chemical composition among periods. There were differences (P < 0.01) among periods for estimated DM intake, but no differences (P > 0.05) for milk yield (mean 16.8 kg/cow/day), milk fat or protein content (mean 31.8 and 28.8 g/kg). Multi-species pastures are a viable alternative for SSDS in the highlands of central Mexico, being more resistant to harsh environment and to weed and kikuyu grass invasion.

RESUMO

OBJECTIVES: We report the results of the reverse transcriptase (RT)/protease (PR) transmitted drug resistance (TDR) prevalence study in 2018, focusing on doravirine resistance-associated mutations and the differences observed when Stanford or French National Agency for AIDS Research (ANRS)/Spanish Network of AIDS Research (RIS)/IAS-USA resistance interpretation algorithms are used to describe clinically relevant resistance. METHODS: We used the WHO 2009 list to investigate the prevalence of NNRTI, NRTI and PI TDR, in treatment-naive HIV-1-infected patients, adding mutations E138A/G/K/Q/R, V106I, V108I, V179L, G190Q, H221Y, F227C/L/V, M230IDR, L234I, P236L and Y318F in RT. The prevalence of doravirine resistance-associated mutations, as described by Soulie et al. in 2019, was evaluated. Clinically relevant TDR was investigated using the latest versions of ANRS, RIS, IAS-USA and Stanford algorithms. RESULTS: NNRTI mutations were detected in 82 of 606 (13.5%) patients. We found 18 patients (3.0%) with NRTI mutations and 5 patients (0.8%) with PI mutations. We detected 11 patients harbouring doravirine resistance-associated mutations (prevalence of 1.8%). Furthermore, we observed important differences in clinically relevant resistance to doravirine when ANRS/RIS (0.7%), IAS-USA (0.5%) or Stanford algorithms (5.0%) were used. V106I, which was detected in 3.8% of the patients, was the main mutation driving these differences. V106I detection was not associated with any of the clinical, demographic or virological characteristics of the patients. CONCLUSIONS: The prevalence of NRTI and PI TDR remains constant in Spain. Doravirine TDR is very infrequent by RIS/ANRS/IAS-USA algorithms, in contrast with results using the Stanford algorithm. Further genotype-phenotype studies are necessary to elucidate the role of V106I in doravirine resistance.

RESUMO

Risk, severity, and outcome of infection depend on the interplay of pathogen virulence and host susceptibility. Systematic identification of genetic susceptibility to infection is being undertaken through genome-wide association studies, but how to expeditiously move from genetic differences to functional mechanisms is unclear. Here, we use genetic association of molecular, cellular, and human disease traits and experimental validation to demonstrate that genetic variation affects expression of VAC14, a phosphoinositide-regulating protein, to influence susceptibility to Salmonella enterica serovar Typhi (S Typhi) infection. Decreased VAC14 expression increased plasma membrane cholesterol, facilitating Salmonella docking and invasion. This increased susceptibility at the cellular level manifests as increased susceptibility to typhoid fever in a Vietnamese population. Furthermore, treating zebrafish with a cholesterol-lowering agent, ezetimibe, reduced susceptibility to S Typhi. Thus, coupling multiple genetic association studies with mechanistic dissection revealed how VAC14 regulates Salmonella invasion and typhoid fever susceptibility and may open doors to new prophylactic/therapeutic approaches.

RESUMO

BACKGROUND: Integrase strand-transfer inhibitors (INSTIs) constitute at present one of the pillars of first-line ART. OBJECTIVES: To study the prevalence of and the trend in transmitted drug resistance (TDR) to INSTIs in ART-naive patients in Spain. METHODS: During the period 2012-17, 1109 patients from CoRIS were analysed. The Stanford algorithm v8.7 was used to evaluate TDR and transmission of clinically relevant resistance. To describe individual mutations/polymorphisms, the most recent IAS list (for INSTIs) and the 2009 WHO list update (for the backbone NRTIs used in combination with INSTIs in first-line treatment) were used. RESULTS: Clinically relevant resistance to the INSTI class was 0.2%: T66I, 0.1%, resistance to elvitegravir and intermediate resistance to raltegravir; and G163K, 0.1%, intermediate resistance to raltegravir and elvitegravir. No clinical resistance to dolutegravir or bictegravir was observed. The prevalence of INSTI TDR following the IAS-USA INSTI mutation list was 2.6%, with no trend towards changes in the prevalence throughout the study period. The overall prevalence of NRTI WHO mutations was 4.3%, whereas clinically relevant resistance to tenofovir, abacavir and emtricitabine/lamivudine was 1.7%, 1.9% and 0.7%, respectively. CONCLUSIONS: Given the low prevalence of clinically relevant resistance to INSTIs and first-line NRTIs in Spain, it is very unlikely that a newly diagnosed patient will present with clinical resistance to a first-line INSTI-based regimen. These patients may not benefit from INSTI and NRTI baseline resistance testing.

RESUMO

INTRODUCTION: In this report we describe a series of patients with a previously undescribed headache. METHODS: Over a 4-year period, we recruited 14 patients with a distinctive type of head pain of unknown cause that did not meet diagnostic criteria for other primary headaches. RESULTS: Nine women and five men with a mean age of 49.6 years (standard deviation, 17.8) presented with spontaneous headache attacks lasting 2-15 minutes. In each attack, the pain was localized to a region of one side of the head. Pain location varied between episodes in 12 patients. Pain quality was pressing, and pain intensity was mild to severe. There were no accompanying symptoms. Physical examination and all ancillary tests were unremarkable. Among seven patients who tried pharmacological treatments, one responded to antidepressants, another to indomethacin and three to other nonsteroidal anti-inflammatory drugs or simple analgesics. CONCLUSIONS: Paroxysmal pressing headache may be a new headache syndrome marked by short duration of the pain and shifting location.

RESUMO

OBJECTIVE: Pain in chronic venous ulcers (CVUs) notably increases with the usual cleaning of the wound. Chronic pain is usually poorly controlled even with the multiple analgesic treatments available. Analgesics can have different serious adverse effects and medical interactions in old patients with several comorbidities. This study reports the efficacy and safety of topical sevoflurane for treatment of pain in CVUs. METHODS: We report a descriptive and retrospective study of 30 patients older than 65 years with painful CVUs refractory to conventional analgesic treatments. Patients received topical sevoflurane treatment before the usual cleaning of the ulcer. Cleaning visits with sevoflurane every 2 days for a period of 1 month were scheduled. We compared the visual analog scale results and analgesic drugs for cleaning with and without topical sevoflurane. The systemic pharmacokinetics of sevoflurane after topical application has not been determined. RESULTS: Pain related to CVUs decreased with topical sevoflurane. Sevoflurane had an analgesic effect with latency time between 2 and 7 minutes. The duration of analgesia ranged between 8 and 18 hours. The time needed to take an analgesic treatment increased after application of sevoflurane. The use of other conventional analgesic drugs, including paracetamol, metamizole, nonsteroidal anti-inflammatory drugs, tramadol, and major opioids, was progressively reduced. The main local adverse effects were mild and transient, including heat, pruritus, and erythema. There were no systemic adverse effects. CONCLUSIONS: Topical sevoflurane has an intense, fast, and long-lasting local analgesic effect with an adequate safety profile. It also diminishes the taking of other conventional analgesic drugs. Topical sevoflurane is an efficient and safe therapeutic alternative for refractory painful CVUs.

RESUMO

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder among reproductive-aged women and the main cause of infertility due to anovulation. However, this syndrome spans the lives of women affecting them from in-utero life until death, leading to several health risks that can impair quality of life and increase morbidity and mortality rates. Fetal programming may represent the beginning of the condition characterized by hyperandrogenism and insulin resistance which leads to a series of medical consequences in adolescence, adulthood, and old age. Menstrual and fertility problems evolve into metabolic complications as age advances. An early and precise diagnosis is important for an adequate management of PCOS, especially at the extreme ends of the reproductive lifespan. However, many different phenotypes are included under the same condition, being important to look at these different phenotypes separately, as they may require different treatments and have different consequences. In this way, PCOS exhibits a great metabolic complexity and its diagnosis needs to be revised once again and adapted to recent data obtained by new technologies. According to the current medical literature, lifestyle therapy constitutes the first step in the management, especially when excess body weight is associated. Pharmacotherapy is frequently used to treat the most predominant manifestations in each age group, such as irregular menses and hirsutism in adolescence, fertility problems in adulthood, and metabolic problems and risk of cancer in old age. Close surveillance is mandatory in each stage of life to avoid health risks which may also affect the offspring, since fetal and post-natal complications seem to be increased in PCOS women.

RESUMO

The goal of this study was to improve an already established reference method, such as the one devoted to organotin compounds determination (Reference Method for Marine Pollution Studies, No. 59, UNEP). The proposed upgrade consists of replacing the mechanical shaking by ultrasound energy and applying low temperature throughout the whole procedure. The optimization of the new operational conditions was performed by using a factorial design. Quality control was performed using a certified sediment reference material (PACS-2) for sediments (82.5-97% of recovery) and recoveries on spiked samples for suspended particulate matter (SPM) and mussels (94-100%). The proposed procedure was applied to surface sediment samples, SPM, and native bivalve mollusks (Brachidontes rodriguezii) collected in Bahia Blanca estuary, a very industrialized zone. The relative standard deviation (RSD %) of the environmental samples were less than 7.9%. It is important to note that the proposed procedure reduced the sample pretreatment time about seven times.

RESUMO

INTRODUCTION: Spontaneous bacterial peritonitis is an infectious complication with a negative impact on survival of patients with cirrhosis. OBJECTIVE: To analyze the short- and long-term survival after a first episode of bacterial peritonitis and the associated prognostic factors. PATIENTS AND METHODS: This was a retrospective, multicenter study of patients admitted to hospital for spontaneous bacterial peritonitis between 2008 and 2013. Independent variables related to mortality were analyzed by logistic regression. The prognostic power of the Child Pugh Score, the Model for End-Stage Liver Disease (MELD) and the Charlson index was analyzed by ROC curve. RESULTS: A total of 159 patients were enrolled, 72% were males with a mean age of 63.5 years and a mean MELD score of 19 (SD ± 9.5). Mortality at 30 and 90 days and one and two years was 21%, 31%, 55% and 69%, respectively. Hepatic encephalopathy (p = 0.008, OR 3.5, 95% CI 1.4-8.8) and kidney function (p = 0.026, OR 2.7, 95% CI 1.13-16.7) were independent factors for short- and long-term mortality. MELD was a good marker of short- and long-term survival (area under the curve [AUC] 0.7: 95% CI 1.02-1.4). The Charlson index was related to long-term mortality (AUC 0.68: 95% CI 0.6-0.77). CONCLUSIONS: Short- and long-term mortality of spontaneous bacterial peritonitis is still high. The main prognostic factors for mortality are impairment of liver and kidney function. MELD and the Charlson index are good markers of survival.

RESUMO

BACKGROUND: In the last few decades, patient satisfaction has become a critical component of quality assessment and is being incorporated into payment for performance plans. However, assessment of satisfaction with anesthesia services is problematic and few validated satisfaction tools have been published. Assessing parent satisfaction with pediatric anesthesia services is even more challenging. OBJECTIVE: Our aim was to develop, implement, and start validating a set of survey questions that evaluate parental satisfaction with the pediatric anesthesia services in order to identify strengths and potential areas for improvement. METHODS: The Pediatric Anesthesia Parent Satisfaction (PAPS) survey contained 17 questions adapted from the American Society of Anesthesiologists Committee on Outcomes and Performance Measures. With consent of the hospital quality improvement committee, the PAPS survey was randomly administered on iPads to 250 English-speaking parents in the main operating room and procedure center postanesthesia care units prior to discharge. Statistical analyses including descriptive statistics, exploratory factor analysis, Cronbach's alpha and Raykov's rho coefficients, composite scale creation, correlations between items, composite scores, and overall satisfaction measures were used to provide evidence for a subset of validity and reliability types. RESULTS AND CONCLUSIONS: The PAPS survey is a short and simple tool for evaluation of parent satisfaction with pediatric anesthesia services and provides some evidence for validity and reliability. The majority (greater than 95%) of parents reported were satisfied or very satisfied with the care provided by the pediatric anesthesia department.
