Abstract
BACKGROUND The Hearing Voices Approach, a community-based peer-led support group model, is generating interest as a novel way to engage with psychosis. Hearing Voices (HV) groups are run by peers, 'experts-by-experience', and emphasize group ownership and community-building rather than adherence to a therapist-led, predetermined structure. Diverse beliefs about experiences are respected and viewed as potentially meaningful. Groups work within each individual's explanatory framework to reframe understandings. AIMS This paper describes the effects of participation in Veteran Voices and Visions (VVV) groups, an adaptation of the HV approach, co-led by clinicians and Veteran peer support specialists, adapted for Veterans who have experienced psychosis and receive care at the VA, a large public health system in the United States. METHOD This mixed methods pilot study has a convergent parallel design, integrating quantitative and qualitative data from participants in pre-intervention and post-intervention assessments. RESULTS Over 16 weeks, quantitative analysis showed a statistically significant reduction in distress, due to auditory hallucinations, as measured by the Psychotic Symptom Rating Scales (PSYRATS). The Beliefs about Voices Questionnaire- Revised (BAVQ-R) results showed a reduction in malevolence and omnipotence and an increase in benevolence related to auditory hallucinations, but no change in resistance. Engagement showed a trend-level reduction. Qualitative data from midpoint (Week 8) and endpoint (Week 16) interviews revealed several perceived benefits from groups: 1) normalization and camaraderie, 2) increased hope and confidence, 3) self-understanding and reframing of experiences, and 4) building relationships outside of groups. Overall, VVV groups reduced distress due to voices, negative beliefs about voices, and perceived power of voices. CONCLUSIONS Study findings contribute to a growing body of literature indicating HV groups support those who have experienced psychosis by reducing social isolation and fostering community, which may facilitate social integration. Overall, our findings highlight the potential benefits of adapting HV groups to health systems.

Abstract
Background COVID-19 measures such as masking, social distancing, and staying indoors may mitigate chronic rhinosinusitis (CRS) symptoms. We evaluate whether these measures correlated with improved symptoms in patients with CRS. Methods This retrospective study compared SNOT-22 survey data from the Northwestern CRS Registry at the time of enrollment and at years 1-5 of follow-up. The final sample consisted of 1826 SNOT-22 surveys for 598 patients. April 10, 2020 to December 31, 2021 was considered "during the pandemic" and prior to March 11, 2020 was considered "pre-pandemic." Wilcoxon test was used to compare SNOT22 at enrollment pre-pandemic versus during pandemic. Separate linear mixed models were performed to estimate SNOT22 at 1 to 5 years after enrollment pre-pandemic versus during pandemic. Results Subjects enrolled during the pandemic had worse SNOT22 scores than those enrolled pre-pandemic (53 vs. 42, p = .0024). Total SNOT-22 scores were improved during the pandemic than before the pandemic at 1 year follow-up (18.17 vs. 12.22, p = .001). This effect persists when evaluating the nasal (7.33 vs. 5.13, p = .003), sleep (2.63 vs. 1.39, p = .008), function (1.40 vs. 0.72, p = .015), and emotion (0.77 vs. 0.17, p < .001) domains individually. There was no statistically significant difference in total SNOT-22 score at Years 2-5 of follow-up. Conclusions Patients with CRS experience a greater reduction in symptom severity in their first year of treatment during the pandemic than before the pandemic, plausibly from measures such as masking and staying indoors. Level of Evidence 4.

Strong and consistent associations of precedent chronic rhinosinusitis with risk of non-cystic fibrosis bronchiectasis. J Allergy Clin Immunol 2022; 150:701-708.e4. [PMID: 35314187 PMCID: PMC9463084 DOI: 10.1016/j.jaci.2022.03.006] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2021] [Revised: 01/20/2022] [Accepted: 03/03/2022] [Indexed: 11/24/2022]
Abstract
BACKGROUND Chronic rhinosinusitis (CRS) and bronchiectasis commonly co-occur, but most prior studies were not designed to evaluate temporality and causality. OBJECTIVES In a sample representing the general population in 37 counties in Pennsylvania, and thus the full spectrum of sinonasal and relevant lung diseases, we aimed to evaluate the temporality and strength of associations of CRS with non-cystic fibrosis bronchiectasis. METHODS We completed case-control analyses for each of 3 primary bronchiectasis case finding methods. We used electronic health records to identify CRS and bronchiectasis with diagnoses, procedure orders, and/or specific text in sinus or chest computerized tomography scan radiology reports. The controls never had any indication of bronchiectasis and were frequency-matched to the 3 bronchiectasis groups on the basis of age, sex, and encounter year. There were 5,329 unique persons with bronchiectasis and 33,363 without bronchiectasis in the 3 analyses. Important co-occurring conditions were identified with diagnoses, medication orders, and encounter types. Logistic regression was used to evaluate associations (odds ratios [ORs] and 95% CIs) of CRS with bronchiectasis while adjusting for confounding variables. RESULTS In adjusted analyses, CRS was consistently and strongly associated with all 3 bronchiectasis definitions. The strongest associations for CRS (ORs and 95% CIs) were those that were based on the text of sinus computerized tomography scan reports; the associations were generally stronger for CRS without nasal polyps (eg, OR = 4.46 [95% CI = 2.09-9.51] for diagnosis-based bronchiectasis). On average, CRS was identified more than 6 years before bronchiectasis. CONCLUSION Precedent CRS was strongly and consistently associated with increased risk of bronchiectasis.

Abstract
PURPOSE This study aimed to evaluate markers of cardiac damage (total CK, CKMB and CRP), inflammatory markers (free iron, homocysteine and TNF-α) as well as lipidogram in breast cancer patients undergoing acute cycles of doxorubicin (DOX), paclitaxel (PTX) or trastuzumab (TZ) and to verify if there is an association between these markers and the toxicity of the chemotherapeutic treatment. Methods: Included in the study were 120 breast cancer patients and 50 healthy controls. All analyzes were performed on automated systems. For the statistical analysis, each group was compared with the controls according to their normality by Student's t-test and Mann-Whitney test. Results: Our results showed that DOX treatment led to increased hsCRP (4.80 ± 1.23 mg/dL, p = 0.0005), triglycerides (187.6 ± 25.06, p = 0.0231), TNF-α (42.31 ± 17.96 pg/mL, p = 0.01) and Fe levels (138.8 ± 18.6 μg/dL, p = 0.0193). In the meantime, PTX induced changes in CK-MB (8.78 ± 4.2 U/L, p = 0.0361), hsCRP (7.12 ± 1.87 mg/dL, p = 0.0006), cholesterol (201.7 ± 19.54, p = 0.05), triglycerides (201.7 ± 19.54, p = 0.0277), TNF-α (38.27 ± 9.12 pg/mL, p = 0.023), homocysteine (10.95 ± 0, 86 μmol/L, p = 0.005), and free iron (113 ± 18 6 μg/dL, p = 0.045) while TZ augmented CK-MB (6.9 ± 1.97 U/L, p < 0.00), hsPCR (3.12 ± 0.68 mg/dL, p = 0.095), cholesterol (218.3 ± 16.79, p = 0.0317), triglycerides (218.3 ± 16.79, p = 0.0127), TNF-α (89.6 ± 12.11, p = 0.032), homocysteine (9.95 ± 1.15 μmol/L, p = 0.0396), free iron (120.5 ± 4.64 μg/dl, p = 0.0058) as well. Conclusions: Our data demonstrated the existence of a proinflammatory net triggered by breast cancer chemotherapy that could increase cardiomyocytes permeability and allow the leakage of circulating proteins as CK-MB and induce the production of hsCRP.

Abstract
Array programming provides a powerful, compact and expressive syntax for accessing, manipulating and operating on data in vectors, matrices and higher-dimensional arrays. NumPy is the primary array programming library for the Python language. It has an essential role in research analysis pipelines in fields as diverse as physics, chemistry, astronomy, geoscience, biology, psychology, materials science, engineering, finance and economics. For example, in astronomy, NumPy was an important part of the software stack used in the discovery of gravitational waves1 and in the first imaging of a black hole2. Here we review how a few fundamental array concepts lead to a simple and powerful programming paradigm for organizing, exploring and analysing scientific data. NumPy is the foundation upon which the scientific Python ecosystem is constructed. It is so pervasive that several projects, targeting audiences with specialized needs, have developed their own NumPy-like interfaces and array objects. Owing to its central position in the ecosystem, NumPy increasingly acts as an interoperability layer between such array computation libraries and, together with its application programming interface (API), provides a flexible framework to support the next decade of scientific and industrial analysis. NumPy is the primary array programming library for Python; here its fundamental concepts are reviewed and its evolution into a flexible interoperability layer between increasingly specialized computational libraries is discussed.

Abstract
The European Position Paper on Rhinosinusitis and Nasal Polyps 2020 is the update of similar evidence based position papers published in 2005 and 2007 and 2012(1-3). The core objective of the EPOS2020 guideline is to provide revised, up-to-date and clear evidence-based recommendations and integrated care pathways in ARS and CRS. EPOS2020 provides an update on the literature published and studies undertaken in the eight years since the EPOS2012 position paper was published and addresses areas not extensively covered in EPOS2012 such as paediatric CRS and sinus surgery. EPOS2020 also involves new stakeholders, including pharmacists and patients, and addresses new target users who have become more involved in the management and treatment of rhinosinusitis since the publication of the last EPOS document, including pharmacists, nurses, specialised care givers and indeed patients themselves, who employ increasing self-management of their condition using over the counter treatments. The document provides suggestions for future research in this area and offers updated guidance for definitions and outcome measurements in research in different settings.

Abstract
Allergic rhinitis, chronic rhinosinusitis, and asthma are highly prevalent, multifactorial chronic airway diseases. Several environmental and genetic factors affect airway epithelial dynamics leading to activation of inflammatory mechanisms in the airways. This review links environmental factors to host epithelial immunity in airway diseases. Understanding altered homeostasis of the airway epithelium might provide important targets for diagnostics and therapy of chronic airway diseases.

The document provides suggestions for future research in this area and offers updated guidance for definitions and outcome measurements in research in different settings. EPOS2020 contains chapters on definitions and classification where we have defined a large number of terms and indicated preferred terms. A new classification of CRS into primary and secondary CRS and further division into localized and diffuse disease, based on anatomic distribution is proposed. There are extensive chapters on epidemiology and predisposing factors, inflammatory mechanisms, (differential) diagnosis of facial pain, allergic rhinitis, genetics, cystic fibrosis, aspirin exacerbated respiratory disease, immunodeficiencies, allergic fungal rhinosinusitis and the relationship between upper and lower airways. The chapters on paediatric acute and chronic rhinosinusitis are totally rewritten. All available evidence for the management of acute rhinosinusitis and chronic rhinosinusitis with or without nasal polyps in adults and children is systematically reviewed and integrated care pathways based on the evidence are proposed. Despite considerable increases in the amount of quality publications in recent years, a large number of practical clinical questions remain. It was agreed that the best way to address these was to conduct a Delphi exercise . The results have been integrated into the respective sections. Last but not least, advice for patients and pharmacists and a new list of research needs are included.

Abstract
Introduction: Chronic rhinosinusitis (CRS) is a broad heterogeneous inflammatory disorder of the nose and paranasal sinuses, resulting from the dysfunctional interplay between host immunity, defective epithelial barrier, and environmental factors. CRS with nasal polyps (CRSwNP) is considered a more severe clinical phenotype with greater burden of symptoms and higher relapse rate, especially with comorbid asthma or aspirin sensitivity. Available treatment options after endoscopic sinus surgery (ESS) - systemic corticosteroids or revision surgery - have significant risks and limitations. Areas covered: Bioabsorbable, steroid-eluting implants have been studied extensively for the ability to dilate and re-establish sinus patency by the localized, controlled delivery of topical corticosteroids to diseased sinonasal lining and nasal polyps. This review provides a comprehensive, up to date analysis of the literature regarding a novel, office-based, mometasone furoate (MF) sinus implant that may treat patients with recurrent CRSwNP after ESS. Expert commentary: Clinical evidence has demonstrated the safety and efficacy of steroid-eluting implant in the reduction of polyp size, symptom burden, and the need for revision sinus surgery. MF sinus implants may play an important role in the management of patients with recurrent polyposis after sinus surgery.

Abstract
Background Staphylococcal exotoxins have been implicated in the pathogenesis of several chronic inflammatory diseases including atopic dermatitis (AD), asthma, and, most recently, chronic rhinosinusitis with nasal polyposis (CRS/NP). In severe AD, these toxins act both as superantigens (SAg), triggering massive T-cell activation, and as conventional allergens, triggering toxin-specific immunoglobulin E (IgE) in the serum. In CRS/NP, evidence for both processes has been reported but it is unclear whether these processes are linked. The aim of this study was to correlate SAg activity as inferred by staphylococcal-specific T-cell receptor (TCR) V-β expansion in the polyp and blood of CRS/NP patients with staphylococcal-specific anti-IgE antibodies in the serum. Methods IgE antibodies to staphylococcal exotoxin A (SEA), staphylococcal exotoxin B (SEB), and toxic shock syndrome toxin (TSST) 1 were measured in the serum of 12 individuals with CRS/NP before functional endoscopic sinus surgery. Flow cytometry was used to analyze the SEA, SEB, and TSST-1–specific TCR V-β domains on the T cells from the polyp and blood of these patients. Results Serum SEA-, SEB-, and TSST-1-specific IgE antibodies were detected in 0/12 (0%), 6/12 (50.0%), and 9/12 (75%) of CRS/NP patients, respectively. Evidence of SAg effect in the polyp lymphocytes (TCR V-β expansion in both CD4+ and CD8+ subsets) was noted in 7/12 (58.3%) patients. Five of 6 CRS/NP patients had overlapping evidence of a systemic IgE response and TCR V-β expansion, suggestive of exposure to the same exotoxin. No patients had evidence a SAg effect in blood lymphocytes. Nine of 12 subjects also had coexistent asthma. Conclusion These results provide evidence for a local SAg effect in 7/12 (58.3%) polyp patients and establish a positive correlation of V-β expansion with the presence of corresponding toxin-specific IgE in the serum.

Abstract
BACKGROUND In neurological diseases presenting with a plethora of symptoms, the value of bodily functions for a given patient might be a guide for clinical management. Multiple sclerosis (MS) is paradigmatic in this respect, and little is known about the value of different bodily functions of patients and their physicians' perceptions. METHODS In a multicenter study, 171 patients with relapsing-remitting multiple sclerosis (RRMS), 61% with a clinically active disease within the last 2 years were followed over up to 3 years and yearly patients and their study physician rated on the perceived value of 13 bodily functions via a priority list. Differences between patients and physicians as well as modulating disease demographic factors were analyzed. RESULTS Patients with RRMS rated visual function followed by thinking and memory and walking highest while physicians stressed mobility, followed by thinking and memory and alertness most. Ratings were independent from disease duration or disability. Strongest value judgment differences were seen in swallowing regarded more relevant by patients and hand function regarded more relevant by physicians. In general, patients' and physicians' ratings through time were quite stable. Collapsing physical items into a physical functioning scale and mental items in a mental function scale, both dimensions were regarded equally important by patients while physicians underscored physical functioning (P = .016). CONCLUSION There are differences between patients and physicians in value statements of bodily functions in MS. In particular, visual functioning is under-recognized by physicians.

Abstract
INTRODUCTION Chronic rhinosinusitis (CRS) is a broad clinical syndrome linked by mucosal inflammation. Primary treatment modalities are corticosteroids and antibiotics with surgery an option for failures, but the level of supporting evidence is generally low. The primary reason is that CRS is a symptom complex and not a specific disease. Areas covered: The primary treatment modalities for CRS are corticosteroids, antibiotics and surgery. Corticosteroids, which have very broad anti-inflammatory properties, also have the strongest evidence for efficacy. Antibiotics are likely effective in a subpopulation of patients but the various phenotypes and endotypes that make up CRS have thus far been poorly defined. Early surgery as well as biologics may also be more efficacious and cost effective in some phenotypes as well. Expert commentary: A better understanding of the inflammatory pathways that drive CRS will permit investigators to separate patient groups. This will allow for clinical trials that target specific subpopulations and more personalized therapy for CRS patients in the future.

Abstract
Abstract
Epithelial barrier dysfunction is thought to play a role in many mucosal diseases including asthma, chronic rhinosinusitis (CRS), and eosinophilic esophagitis (EoE). Oncostatin M (OSM), was elevated in both mRNA (28.3 fold, p<.01, n=12) and protein (4.4 fold, p<.05, n=12-19) in the nasal polyps of CRS patients compared to control tissue. OSM protein was also elevated in bronchoalveolar lavage (BAL) of allergic asthma (AA) patients following segmental allergen challenge (SAC) vs. saline challenge (14 fold, p<.0001). Additionally, OSM mRNA was elevated in esophageal biopsies of EoE patients vs. controls, (3 fold, p<.01). OSM stimulation of differentiated airway epithelium induced barrier dysfunction, as measured by decreased transepithelial electrical resistance (63% reduction, p<.0001, n=11) and increased permeability to 10kD dextran (2.45 fold, p<.05, n=5). Staining for the tight junction protein, occludin showed that OSM stimulation of differentiated airway epithelium impaired the organization of the tight junctions compared to unstimulated controls (n=5). Levels of OSM protein in tissue lysates from CRS and controls correlated with levels of α2-macroglobulin, a marker of epithelial leak, in matched nasal secretions (r=.5055, p<.01). Additionally, OSM in the BAL following SAC in AA patients correlated with serum albumin, another marker of epithelial leak (r=.8062, p<.001). These results suggest that OSM may play a role in epithelial barrier dysfunction in mucosal disease.

Abstract
Abstract
Chronic rhinosinusitis (CRS) is an upper airway disease that affects 30 million Americans and a subgroup of CRS patients also has nasal polyps (CRSwNP). In CRSwNP patients, inflamed sinus tissues can be removed as part of treatment, which provides a unique model system to investigate mechanisms of human mucosal inflammation. We have previously reported local elevations in NP of B cells, antibodies (Ab), and expression of Epstein-Barr virus-Induced protein 2 (EBI2), a marker of extrafollicular plasma cells (PC). To characterize the mechanisms mediating these responses, we assessed B cells from fresh tissue (d0) or after 4 days of culture (d4) from NP, uncinate tissue (UT) or tonsils from CRS and control subjects by flow cytometry. We measured Ab production by multiplex array and assessed formation of B cell follicles by immunohistochemistry. We assessed the Ab repertoire by DNA deep sequencing and by analysis of Ab genes from single cells. We found that NP uniquely supported the accumulation of PC (p<0.01) and Ab production (p<0.05) in vitro. Plasmablasts (PB) and PC were Ki67+, and EBI2 expression was highest on PB. We found no evidence for increased B cell follicles in NP compared to control UT (n>10/group). Ab from NP had fewer CDR3 mutations than Ab from UT (p<0.05), but more mutations than Ab from peripheral blood (p<0.05). These data suggest that there is a strong extrafollicular B cell response in NP that may drive Ab production during chronic airway inflammation.

Abstract
Chronic rhinosinusitis (CRS) is a public health problem that has a significant socio-economic impact. Moreover, the complexity of this disease due to its heterogeneous nature based on the underlying pathophysiology - leading to different disease variants - further complicates our understanding and directions for the most appropriate targeted treatment strategies. Several International/national guidelines/position papers and/or consensus documents are available that present the current knowledge and treatment strategies for CRS. Yet there are many challenges to the management of CRS especially in the case of the more severe and refractory forms of disease. Therefore, the International Collaboration in Asthma, Allergy and Immunology (iCAALL), a collaboration between EAACI, AAAAI, ACAAI, and WAO, has decided to propose an International Consensus (ICON) on Chronic Rhinosinusitis. The purpose of this ICON on CRS is to highlight the key common messages from the existing guidelines, the differences in recommendations as well as the gaps in our current knowledge of CRS, thus providing a concise reference. In this document we discuss the definition of the disease, its relevance, pharmacoeconomics, pathophysiology, phenotypes and endotypes, genetics and risk factors, natural history and co-morbidities as well as clinical manifestations and treatment options in both adults and children comprising pharmacotherapy, surgical interventions and more recent biological approaches. Finally, we have also highlighted the unmet needs that wait to be addressed through future research.

Abstract
Individuals with schizophrenia face significant challenges in daily functioning, and although social cognition predicts how well patients respond to these challenges, associated physiological mechanisms remain unspecified. The present study draws from polyvagal theory and tested the hypothesis that respiratory sinus arrhythmia (RSA), an established indicator of the capacity to self-regulate and adapt to environmental demands, combines with social cognition to predict functional outcome. Using data from 41 schizophrenia patients and 36 healthy comparison subjects, we replicated group differences in RSA and social cognition and also demonstrated that RSA and social cognition interact to predict how effectively patients manage work and independent living activities. Specifically, RSA did not enhance functional outcomes when social cognition was already strong, but higher levels of RSA enabled effective role functioning when social-cognitive performance was impaired. Jointly, RSA and social cognition accounted for 40% of the variance in outcome success, compared with 21% when evaluating social cognition alone. As polyvagal theory suggests, physiological flexibility and self-regulatory capacity may compensate for poorer social-cognitive skills among schizophrenia patients.

Does the Cyanophora paradoxa genome revise our view on the evolution of photorespiratory enzymes? PLANT BIOLOGY (STUTTGART, GERMANY) 2013; 15:759-768.

Abstract
In the present-day O2 -rich atmosphere, the photorespiratory pathway is essential for organisms performing oxygenic photosynthesis; i.e. cyanobacteria, algae and land plants. The presence of enzymes for the plant-like 2-phosphoglycolate cycle in cyanobacteria indicates that, together with oxygenic photosynthesis, genes for photorespiratory enzymes were endosymbiotically conveyed from ancient cyanobacteria to photosynthetic eukaryotes. The genome information for Cyanophora paradoxa, a member of the Glaucophyta representing the first branching group of primary endosymbionts, and for many other eukaryotic algae was used to shed light on the evolutionary relationship of photorespiratory enzymes among oxygenic phototrophs. For example, it became possible to analyse the phylogenies of 2-phosphoglycolate phosphatase, serine:glyoxylate aminotransferase and hydroxypyruvate reductase. Analysis of the Cyanophora genome provided clear evidence that some photorespiratory enzymes originally acquired from cyanobacteria were lost, e.g. glycerate 3-kinase, while others were replaced by the corresponding enzymes from the α-proteobacterial endosymbiont, e.g. serine:glyoxylate aminotransferase. Generally, our analysis supports the view that many C2 cycle enzymes in eukaryotic phototrophs were obtained from the cyanobacterial endosymbiont, but during the subsequent evolution of algae and land plants multiple losses and replacements occurred, which resulted in a reticulate provenance of photorespiratory enzymes with different origins in different cellular compartments.

Abstract
Oxygenic photosynthesis would not be possible without photorespiration in the present day O2 -rich atmosphere. It is now generally accepted that cyanobacteria-like prokaryotes first evolved oxygenic photosynthesis, which was later conveyed via endosymbiosis into a eukaryotic host, which then gave rise to the different groups of algae and streptophytes. For photosynthetic CO2 fixation, all these organisms use RubisCO, which catalyses both the carboxylation and the oxygenation of ribulose 1,5-bisphosphate. One of the reaction products of the oxygenase reaction, 2-phosphoglycolate (2PG), represents the starting point of the photorespiratory C2 cycle, which is considered largely responsible for recapturing organic carbon via conversion to the Calvin-Benson cycle (CBC) intermediate 3-phosphoglycerate, thereby detoxifying critical intermediates. Here we discuss possible scenarios for the evolution of this process toward the well-defined 2PG metabolism in extant plants. While the origin of the C2 cycle core enzymes can be clearly dated back towards the different endosymbiotic events, the evolutionary scenario that allowed the compartmentalised high flux photorespiratory cycle is uncertain, but probably occurred early during the algal radiation. The change in atmospheric CO2 /O2 ratios promoting the acquisition of different modes for inorganic carbon concentration mechanisms, as well as the evolutionary specialisation of peroxisomes, clearly had a dramatic impact on further aspects of land plant photorespiration.
