RESUMO

Recent studies suggest that arthropod diversity in German forests is declining. Currently, different national programs are being developed to monitor arthropod trends and to unravel the effects of forest management on biodiversity in forests. To establish effective long-term monitoring programs, a set of drivers of arthropod diversity and composition as well as suitable species groups have to be identified. To aid in answering these questions, we investigated arthropod data collected in four Hessian forest reserves (FR) in the 1990s. To fully utilize this data set, we combined it with results from a retrospective structural sampling design applied at the original trap locations in central European beech (Fagus sylvatica) forests. As expected, the importance of the different forest structural, vegetation, and site attributes differed largely between the investigated arthropod groups: beetles, spiders, Aculeata, and true bugs. Measures related to light availability and temperature such as canopy cover or potential radiation were important to all groups affecting either richness, composition, or both. Spiders and true bugs were affected by the broadest range of explanatory variables, which makes them a good choice for monitoring general trends. For targeted monitoring focused on forestry-related effects on biodiversity, rove and ground beetles seem more suitable. Both groups were driven by a narrower, more management-related set of variables. Most importantly, our study approach shows that it is possible to utilize older biodiversity survey data. Although, in our case, there are strong restrictions due to the long time between species and structural attribute sampling.

RESUMO

BACKGROUND & AIMS: Autoimmune pancreatitis (AIP) is an immune-mediated disease of the pancreas with distinct pathophysiology and manifestations. Our aims were to characterize type 1 AIP in a large pan-European cohort and study the effectiveness of current treatment regimens. METHODS: We retrospectively analyzed adults diagnosed since 2005 with type 1 or not-otherwise-specified AIP in 42 European university hospitals. Type 1 AIP was uniformly diagnosed using specific diagnostic criteria. Patients with type 2 AIP and those who had undergone pancreatic surgery were excluded. The primary end point was complete remission, defined as the absence of clinical symptoms and resolution of the index radiologic pancreatic abnormalities attributed to AIP. RESULTS: We included 735 individuals with AIP (69% male; median age, 57 years; 85% White). Steroid treatment was started in 634 patients, of whom 9 (1%) were lost to follow-up. The remaining 625 had a 79% (496/625) complete, 18% (111/625) partial, and 97% (607/625) cumulative remission rate, whereas 3% (18/625) did not achieve remission. No treatment was given in 95 patients, who had a 61% complete (58/95), 19% partial (18/95), and 80% cumulative (76/95) spontaneous remission rate. Higher (≥0.4 mg/kg/day) corticosteroid doses were no more effective than lower (<0.4 mg/kg/day) doses (odds ratio, 0.428; 95% confidence interval, 0.054-3.387) and neither was a starting dose duration >2 weeks (odds ratio, 0.908; 95% confidence interval, 0.818-1.009). Elevated IgG4 levels were independently associated with a decreased chance of complete remission (odds ratio, 0.639; 95% confidence interval, 0.427-0.955). Relapse occurred in 30% of patients. Relapses within 6 months of remission induction were independent of the steroid-tapering duration, induction treatment duration, and total cumulative dose. CONCLUSIONS: Patients with type 1 AIP and elevated IgG4 level may need closer monitoring. For remission induction, a starting dose of 0.4 mg/kg/day for 2 weeks followed by a short taper period seems effective. This study provides no evidence to support more aggressive regimens.

RESUMO

As the need for high-speed electronics continues to rise rapidly, printed wiring board (PWB) requirements become ever-more demanding. A typical PWB is fabricated by bonding dielectric films such as polyimide to electrically conductive copper foil such as rolled annealed (RA) copper and is expected to become thinner, flexible, durable, and compatible with high-frequency 5G performance. Polyimide films inherently feature a higher coefficient of thermal expansion (CTE) than copper foils; this mismatch causes residual thermal stresses. To attenuate the mismatch, silica nanoparticles may be used to reduce the CTE of PI. A nodulated copper surface can be used to enhance the Cu/PI adhesion by additional bonding mechanisms that could include a type of mechanical bonding, which is a focus of this study. In this investigation, a 90° peel test was used to measure the peel strength in copper/polyimide/copper laminates containing nodulated copper and polyimide reinforced with 0, 20, and 40 wt % silica nanoparticles. The influence of silica nanoparticles on the peel strength was quantitatively evaluated. Laminates incorporating polyimide films lacking silica nanoparticles had a ∼3.75× higher peel strength compared with laminates reinforced with 40% silica. Their failure surfaces were analyzed by using scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDX), and X-ray photoelectron spectroscopy to identify the mode of failure and to understand bonding mechanisms. The key bonding mechanism, mechanical interlocking, was achieved when the polyimide surrounded or engulfed the copper nodules when the laminate was created. Post-testing failure surface analysis revealed the presence of copper on the polyimide side and polyimide on the copper side, indicating mixed mode failure. An analytical model was developed to determine the impact of applied pressure, temperature, and time on the polyimide penetration and mechanical interlocking around the copper nodules. The model was validated by measuring the peel strength on another set of specimens fabricated using increased temperature and pressure that showed a 3× increase in peel strength compared to lower temperature/pressure processing conditions. This enhanced adhesion resulted from the lower polymer material viscosity at higher temperatures, which fosters deeper and more complete penetration around the copper nodules during processing at higher pressures for longer durations. The methodology of combining peel testing, viscosity and CTE measurement, SEM/EDX, surface chemical analysis, and penetration depth calculation developed herein enables the calculation of the desired processing parameters to enhance functionality and improve adhesion.

RESUMO

BACKGROUND: Type 2 (T2) inflammation plays a pathogenic role in chronic rhinosinusitis (CRS). The effects of endoscopic sinus surgery (ESS) on T2 inflammation are unknown. OBJECTIVE: The aim of this study was to compare T2 inflammatory biomarkers from middle meatal (MM) mucus for distinguishing patients with CRS from CRS-free patients, identifying major phenotypes (CRS without nasal polyps [CRSsNP] and CRS with nasal polyps [CRSwNP]), assessing endotypic change, and establishing cross-sectional and longitudinal outcomes in patients undergoing ESS. METHODS: MM mucus samples were collected from patients with CRSsNP and patients with CRSwNP before and 6 to 12 months after ESS and compared with samples from CRS-free control patients. T2 biomarkers were evaluated both continuously and using threshold-based definitions of T2 endotype to identify relationships with patient-reported (based on the 22-Item Sinonasal Outcomes Test and Chronic Rhinosinusitis Patient-Reported Outcomes Measure) and clinician-reported (radiographic and endoscopic) severity. Linear mixed models were developed to analyze clinical variables associated with T2 biomarker levels. RESULTS: A total of 154 patients with CRS (89 with CRSsNP and 65 with CRSwNP) were enrolled, with a mean interval of 9 months between ESS and follow-up. An analysis of pre-ESS MM mucus samples revealed elevated levels of T2 mediators in patients with CRSwNP versus in patients with CRSsNP and CRS-free controls. Temporally stable correlations between levels of IL-13 and IL-5, levels of periostin and complement 5a, and levels of eosinophil cationic protein (ECP) and eotaxin-3 were observed. On this basis and on the basis of pathologic significance, levels of IL-13, periostin and ECP were further analyzed. After ESS, levels of IL-13 and periostin decreased significantly, whereas ECP levels remained unchanged. Across pre- and post-ESS evaluation, the T2 endotype was associated with radiographic severity but did not predict outcomes. CRSwNP status and African American race were associated with higher levels of IL-13 and periostin, whereas ECP level was higher in patients undergoing extensive surgery. CONCLUSION: ESS decreased levels of IL-13 and periostin in the middle meatus. T2 inflammation after ESS was correlated with patient- and clinician-reported severity across phenotypes. Pre-ESS T2 inflammation did not predict post-ESS outcomes.

RESUMO

OBJECTIVES: Alcohol and nicotine are the two most important risk factors of chronic pancreatitis and they often occur together. It is still unclear how much they influence the severity of the disease and which of the two addictions should be treated with priority. METHODS: We performed a single-center, retrospective, cross-sectional study in a mixed medicosurgical cohort of 870 patients diagnosed with chronic pancreatitis (CP). We analyzed the impact of the drinking pattern and abstinence for alcohol and nicotine on the course of the disease. Patients with alcoholic CP were subdivided in I) patients with "life-time drinking history" (LTDH), II) "current drinkers" with current alcohol abuse without signs of LTDH, and III) "former drinkers" who stopped or reduced alcohol intake dramatically. RESULTS: Compared to patients with LTDH, "former drinkers" had a lower rate of exocrine insufficiency (29% vs. 59%) and pseudocysts (33% vs. 49%), were more often relapse-free (37% vs. 5%) and had less abdominal pain. There was no correlation detected between the quantity of alcohol consumption and the severity or progression of the disease. Regarding nicotine, 29 pack years are the threshold for developing early stage of CP. Under nicotine abstinence, only slightly more patients were relapse-free (37% vs. 22%). In contrast, the cumulative amount of nicotine consumed correlated with overall disease severity and the development of pseudocysts. The need for surgery was increased with odds ratios of 1.8 for both, alcohol and nicotine abuse. CONCLUSIONS: Alcohol cessation in chronic pancreatitis reduces exocrine insufficiency, abdominal pain and local complications. The effect of nicotine cessation is less pronounced in our cohort. However, nicotine abuse represents an important factor for the development of the disease.

RESUMO

BACKGROUND: Regional anaesthesia has the benefit of reducing the need for systemic analgesia and therefore, potentially reducing undesired side effects. With the end of the sensory nerve block however, many patients report severe pain that requires therapy with opioids and often compromise the initial opioid sparing effect. This study aimed to characterise the postoperative pain profile and the phenomenon of rebound pain after axillary brachial plexus anaesthesia (RA) compared to general anaesthesia (GA). DESIGN: Single-centre observational, stratified cohort study. SETTING: The study was conducted at University Hospital Marburg from May 2020 until September 2022. PARTICIPANTS: One hundred thirty-two patients receiving elective hand and forearm surgery were enrolled in this study. INTERVENTIONS: Group RA received ultrasound-guided brachial plexus anaesthesia via the axillary approach with 30 mL of prilocaine 1% and 10 mL ropivacaine 0.2%. Group GA received balanced or total intravenous general anaesthesia. MAIN OUTCOME MEASURES: Primary endpoint were integrated pain scores (IPS) within 24 h postoperatively. Secondary endpoints were pain scores (NRS 0-10), morphine equivalents, patient satisfaction, quality of recovery and opioid-related side effects. RESULTS: One hundred thirty-two patients were analysed of which 66 patients received brachial plexus block and 66 patients received general anaesthesia. Following RA significantly lower IPS were seen directly after surgery (p < .001) and during the post-anaesthesia care unit interval (p < .001) but equalised after 3 h at the ward. No overshoot in pain scores or increased opioid consumption could be detected. Patient satisfaction and postoperative recovery were comparable between both groups. CONCLUSION: The IPS and NRS was initially lower in the RA group, increased with fading of the block until equal to the GA group and equal thereafter. Although various definitions of rebound pain were met during this phase, the opioid sparing effect of regional anaesthesia was not counteracted by it. The incidence of episodes with uncontrolled, severe pain did not differ between groups. We found no clinical implications of rebound pain in this setting, since the RA group did not show higher pain scores than the GA group at any time point. TRIAL REGISTRATION: German Clinical Trials Register (DRKS00021764).

RESUMO

BACKGROUND: Complications in chronic pancreatitis (CP) can be grouped in inflammatory (ICC) and fibrotic (FCC) clusters and pancreatic insufficiency cluster (PIC). However, the association between etiological risk factors and the development of complication clusters remains obscure. In this study, the impact of the etiology and disease duration on disease onset and development of complications was investigated. METHODS: This cross-sectional study recruited patients with CP from Mannheim/Germany (n = 870), Gießen/Germany (n = 100) und Donetsk/Ukraine (n = 104). Etiological risk factors, disease stage, age at disease onset, complications, need for hospitalization and surgery were noted. RESULTS: In 1074 patients diagnosed with CP, main risk factors were alcohol and nicotine abuse. An earlier onset of the disease was observed upon nicotine abuse (-4.0 years). Alcohol abuse was only associated with an earlier onset of the definite stage of CP. Alcohol abuse was the major risk factor for the development of ICC (p < 0.0001, multiple regression modeling). Abstinence of alcohol reduced ICC, whereas abstinence of nicotine showed no association. PIC correlated with efferent duct abnormalities and the disease duration. In contrast, FCC was mainly dependent on the disease duration (p < 0.0001; t-test). The presence of any complication cluster correlated with the need for surgery (p < 0.01; X2-test). However, only ICC correlated with a prolonged hospital stay (p < 0.05; t-test). CONCLUSIONS: ICC is mainly dependent on alcohol abuse. In contrast, FCC and PIC are mainly dependent on the disease duration. The etiology and disease duration can be used as predictors of the course of disease to provide individual treatment and surveillance strategies.

RESUMO

BACKGROUND: Patients with chronic rhinosinusitis (CRS) may have persistence of polyps, discharge, or edema after endoscopic sinus surgery (ESS). Inflammation in CRS can be classified into three endotypes, with the presence of polyps associated with the type 2 endotype. Here, we evaluate the endotypic underpinnings of discharge or edema without polyps after ESS. METHODS: At a visit 6-12 months post ESS, patients underwent endoscopy and completed the CRS-PRO and SNOT-22. Luminex analysis of middle meatal mucus obtained at that visit was performed for IFN-γ, ECP, and IL-17a. Type 1, 2, and 3 endotypes were defined as greater than the 90th percentile expression of each marker, respectively, in controls. Wilcoxon rank-sum and chi-squared tests were used to compare cytokine levels and endotype prevalence between those with and without endoscopic findings. RESULTS: A total of 122 CRS patients completed a clinical exam (median: 8.2 months post ESS). Of the 122 patients, 107 did not have polyps on endoscopy. Of these 107 patients, 48 had discharge, 44 had edema, and 46 had neither discharge nor edema. Compared with those patients without any findings, patients with discharge or edema reported significantly worse severity as measured by CRS-PRO (10.5 vs. 7.0, p = 0.009; 12.0 vs. 7.0, p < 0.001; respectively), and had higher post-ESS IFN-γ, ECP, and IL-17a. Patients with discharge had higher prevalence of only T1 and T3 endotypes, while patients with edema had higher prevalence of only the T3 endotype. CONCLUSIONS: Post-ESS discharge or edema in the absence of polyps was associated with higher patient-reported outcome severity and was more strongly associated with type 1 or 3 inflammation.

RESUMO

OBJECTIVES: To explore the degree to which patients undergoing unilateral endoscopic sinus surgery (ESS) experience post-operative contralateral sinonasal symptoms and determine risk factors for contralateral symptomatology following unilateral ESS. METHODS: Patients who underwent unilateral surgery for chronic rhinosinusitis (CRS) were contacted and asked if they felt symptomatic on the contralateral side at that point in time. Nasal Obstruction Symptom Evaluation (NOSE) scores were obtained based on contralateral symptomatology they recalled at the following time points: pre-ESS, 1 month post-ESS, and 3 months post-ESS. Demographics, contralateral symptomatology, and NOSE scores were compared between those with 2 or fewer sinusotomies versus 3 or more sinusotomies. RESULTS: Of the 97 patients included in this study, 24% of patients reported contralateral congestion, a median of 24 months post-ESS, and more than 10% of patients reported other contralateral symptoms including swelling, rhinorrhea, difficulty breathing, and hyposmia post-ESS. Those with 2 or fewer sinusotomies were more likely to feel that they had developed worsened sensation of contralateral sinus swelling (P = .008). The median amount of time from the participants' index surgery until the time they were interviewed was 24 months. There were no differences in long-term contralateral symptomatology between those who did and did not have septoplasty (27%). CONCLUSION: Patients who have unilateral ESS for CRS may experience long-term contralateral symptoms. Having a septoplasty did not affect contralateral symptoms.

RESUMO

BACKGROUND: Rebound pain as a side effect of regional anaesthesia is an excessive sensation of pain after the effect of local anaesthesia has subsided. This sensation goes well beyond the normal wound pain following a surgical intervention. This phenomenon has entered focus of research in the past 10 years now, but the specific causes are so far unclear and there are still no targeted treatment recommendations. OBJECTIVE: This review article is intended to give the readership an overview of the current state of research about rebound pain. The theories of pathophysiology are presented and prophylaxis as well as treatment strategies are explained. MATERIAL AND METHODS: For this review article, the publications about rebound pain that appeared from 2005 up to May 2021 in PubMed were reviewed and the authors' definitions of rebound pain as well as the assumptions on pathophysiology and treatment recommendations were summarized. RESULTS AND DISCUSSION: A total of 22 original papers from the years 2005-2021 were evaluated regarding the differences between the definitions of rebound pain, the assumption of its occurrence as well as possible treatment options. It turns out that there is no uniform definition by the professional societies, the pathophysiology has not yet been clearly identified and no clear recommendations for prophylaxis or treatment can be given to date; however, early administration of pain medication (e.g. NSAIDs) before the end of the nerve block has proven to be helpful. Likewise, dexamethasone as an adjuvant to regional anaesthesia shows positive effects regarding the occurrence of rebound pain. In any case, it makes sense to provide patients with comprehensive information about this special side effect of regional anaesthesia so that those affected can correctly classify the excessive pain reaction. Targeted studies to avoid severe pain after regional anaesthesia, e.g. through the addition of adjuvants, are necessary in order to keep side effects as low as possible and thereby improve patient comfort and the acceptance of regional anaesthesia.

RESUMO

The 22-item Sino-Nasal Outcome Test (SNOT-22) and 12-item Patient Reported Outcomes in Chronic Rhinosinusitis (CRS-PRO) instrument are validated patient-reported outcomes measures in CRS. In this study we assess the correlation of these with type 2 (T2) biomarkers before and after endoscopic sinus surgery (ESS). METHODS: Middle meatal mucus data were collected and the SNOT-22 and CRS-PRO were administered to 123 patients (71 CRS without nasal polyps [CRSsNP], 52 CRS with nasal polyps [CRSwNP]) with CRS before and 6 to 12 months after undergoing ESS. Interleukin (IL)-4, IL-5, IL-13, and eosinophilic cationic protein (ECP) were measured using a multiplexed bead assay and enzyme-linked immunoassay. Pre- and post-ESS SNOT-22 and CRS-PRO were compared with T2 biomarkers. RESULTS: Before ESS neither PROM correlated with any biomarker. After ESS, CRS-PRO showed a correlation with 2 mediators (IL-5 and IL-13: p = 0.012 and 0.003, respectively) compared with none for the SNOT-22. For CRSwNP patients, pre-ESS CRS-PRO and SNOT-22 correlated with IL-4 (p = 0.04 for both). However, after ESS, CRS-PRO correlated with 3 biomarkers (IL-5, IL-13, and ECP: p = 0.02, 0.024, and 0.04, respectively) and SNOT-22 with 2 biomarkers (IL-5 and IL-13: p = 0.038 and 0.02, respectively). There were no significant relationships between any of the T2 biomarkers pre- or post-ESS among patients with CRSsNP. Exploratory analyses of the subdomains showed the SNOT-22 rhinologic and CRS-PRO rhinopsychologic subdomains correlated better with the T2 biomarkers. On individual item analysis, IL-13 correlated significantly post-ESS with 8 of 12 items on the CRS-PRO vs 6 of 22 items on the SNOT-22. CONCLUSION: The CRS-PRO total score showed a significant correlation with T2 biomarkers especially when assessed post-ESS and among CRSwNP patients.

RESUMO

BACKGROUND: Mometasone-eluting stents (MES) have demonstrated improvement in short-term endoscopic outcomes and reduce short- to medium-term rescue interventions. Their effect on the local inflammatory environment, longer-term patient-reported outcomes, and radiographic severity have not been studied. METHODS: Middle meatal mucus and validated measures of disease severity were collected before and 6 to 12 months after endoscopic surgery in 52 patients with chronic rhinosinusitis with nasal polyps (CRSwNPs). Operative findings, type 2 mediator concentrations, intraoperative variables, and disease severity measures were compared between those who did and those who did not receive intraoperative frontal MES. RESULTS: A total of 52 patients with CRSwNPs were studied; 33 received frontal MES and were compared with 19 who did not. Pre-endoscopic sinus surgery (ESS) middle meatus (MM) interleukin (IL) 13 and eosinophil cationic protein (ECP) were higher in the stented group (p < 0.05), but pre-ESS clinical measures of disease severity were similar as were surgical extent and post-ESS medical management. Intraoperative eosinophilic mucin was more frequent in the stented group (58% vs 11%, p = 0.001). IL-5 (p < 0.05) and IL-13 (p < 0.001) decreased post-ESS in the stented group, but this was not observed in the nonstented group. Post-ESS IL-4 and IL-13 were higher in the nonstented vs stented group (p < 0.05 for both). CONCLUSION: Although patients who received intraoperative frontal MES had significantly higher pre-ESS MM IL-13 and ECP, patients who received frontal MES had lower concentrations of IL-4 and IL-13 than those who did not at a median of 8 months post-ESS. However, these changes did not correspond to significantly different measures of symptomatic or radiographic disease severity.

RESUMO

Color polymorphism offers rich opportunities for studying the eco-evolutionary mechanisms that drive the adaptations of local populations to heterogeneous and changing environments. We explored the color morph diversity and composition in a Chrysomela lapponica leaf beetle across its entire distribution range to test the hypothesis that environmental and climatic variables shape spatiotemporal variation in the phenotypic structure of a polymorphic species. We obtained information on 13 617 specimens of this beetle from museums, private collections, and websites. These specimens (collected from 1830-2020) originated from 959 localities spanning 33° latitude, 178° longitude, and 4200 m altitude. We classified the beetles into five color morphs and searched for environmental factors that could explain the variation in the level of polymorphism (quantified by the Shannon diversity index) and in the relative frequencies of individual color morphs. The highest level of polymorphism was found at high latitudes and altitudes. The color morphs differed in their climatic requirements; composition of colour morphs was independent of the geographic distance that separated populations but changed with collection year, longitude, mean July temperature and between-year temperature fluctuations. The proportion of melanic beetles, in line with the thermal melanism hypothesis, increased with increasing latitude and altitude and decreased with increasing climate seasonality. Melanic morph frequencies also declined during the past century, but only at high latitudes and altitudes where recent climate warming was especially strong. The observed patterns suggest that color polymorphism is especially advantageous for populations inhabiting unpredictable environments, presumably due to the different climatic requirements of coexisting color morphs.

RESUMO

BACKGROUND/OBJECTIVES: In chronic pancreatitis (CP), progressive fibrosis of the pancreas leads to exocrine and endocrine insufficiency and, finally, to pancreatic burnout. Alcohol consumption is associated with fibrosis in the pancreas and the liver, and the activation of stellate cells plays a central role in the induction of fibrosis in both organs. However, the relationship between pancreatic burnout and liver cirrhosis (LC) is still poorly understood in patients with alcoholic CP (ACP). METHODS: We performed a single-center, retrospective, cross-sectional study with 537 CP patients. We analyzed the clinical presence of early and advanced pancreatic burnout and stated LC in cases of typical alterations in histology, liver stiffness measurement, cross-sectional imaging, or ultrasound. We analyzed further clinical parameters. RESULTS: The frequency of advanced pancreatic burnout was 6.5% for ACP (20/306) and 4% for non-ACP (8/206; p = 0.20; χ2 test). Advanced pancreatic burnout was not associated with the amount of alcohol consumption (p = 0.34) but with the disease duration (p = 0.0470) and rate of calcification (p = 0.0056). Furthermore, advanced pancreatic burnout was associated with LC (p < 0.0001) but cannot be explained by the amount of alcohol consumption. In ACP with alcohol consumption >80 g/day, an isolated LC was significantly more frequently detectable (14%, without pancreatic burnout) than an isolated advanced pancreatic burnout (1%, without LC). These results were confirmed by multivariable analyses. CONCLUSIONS: We identified a close association between LC and pancreatic burnout. The disease duration positively correlates with the development of pancreatic burnout. The liver seems to be more vulnerable to alcohol than the pancreas.

RESUMO

Today, the Internet of Things (IoT) is pervasive and characterized by the rapid growth of IoT platforms across different application domains, enabling a variety of business models and revenue streams. This opens new opportunities for companies to extend their collaborative networks and develop innovative cross-platform and cross-domain applications. However, the heterogeneity of today's platforms is a major roadblock for mass creation of IoT platform ecosystems, pointing at the current absence of technology enablers for an easy and innovative composition of tools/services from the existing platforms. In this paper, we present the Data Spine, a federated platform enabler that bridges IoT interoperability gaps and enables the creation of an ecosystem of heterogeneous IoT platforms in the manufacturing domain. The Data Spine allows the ecosystem to be extensible to meet the need for incorporating new tools/services and platforms. We present a reference implementation of the Data Spine and a quantitative evaluation to demonstrate adequate performance of the system. The evaluation suggests that the Data Spine provides a multitude of advantages (single sign-on, provision of a low-code development environment to support interoperability and an easy and intuitive creation of cross-platform applications, etc.) over the traditional approach of users joining multiple platforms separately.

RESUMO

Chronic rhinosinusitis with nasal polyps (CRSwNP) represents a challenging disease entity with significant rates of recurrence following appropriate medical and surgical therapy. Recent approval of targeted biologics in CRSwNP compels deeper understanding of underlying disease pathophysiology. Both of the approved biologics for CRSwNP modulate the type 2 inflammatory pathway, and the majority of drugs in the clinical trials pathway are similarly targeted. However, there remain multiple other pathogenic mechanisms relevant to CRSwNP for which targeted therapeutics already exist in other inflammatory diseases that have not been studied directly. In this article we summarize pathogenic mechanisms of interest in CRSwNP and discuss the results of ongoing clinical studies of targeted therapeutics in CRSwNP and other related human inflammatory diseases.
