Heterogeneity of sensitization profiles and clinical phenotypes among patients with seasonal allergic rhinitis in Southern European countries-The @IT.2020 multicenter study. Allergy 2024; 79:908-923. [PMID: 38311961 DOI: 10.1111/all.16029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 11/30/2023] [Accepted: 12/04/2023] [Indexed: 02/06/2024]
Abstract
BACKGROUND Pollen allergy poses a significant health and economic burden in Europe. Disease patterns are relatively homogeneous within Central and Northern European countries. However, no study broadly assessed the features of seasonal allergic rhinitis (SAR) across different Southern European countries with a standardized approach. OBJECTIVE To describe sensitization profiles and clinical phenotypes of pollen allergic patients in nine Southern European cities with a uniform methodological approach. METHODS Within the @IT.2020 multicenter observational study, pediatric and adult patients suffering from SAR were recruited in nine urban study centers located in seven countries. Clinical questionnaires, skin prick tests (SPT) and specific IgE (sIgE) tests with a customized multiplex assay (Euroimmun Labordiagnostika, Lübeck, Germany) were performed. RESULTS Three hundred forty-eight children (mean age 13.1 years, SD: 2.4 years) and 467 adults (mean age 35.7 years SD: 10.0 years) with a predominantly moderate to severe, persistent phenotype of SAR were recruited. Grass pollen major allergenic molecules (Phl p 1 and/or Phl p 5) ranged among the top three sensitizers in all study centers. Sensitization profiles were very heterogeneous, considering that patients in Rome were highly poly-sensitized (sIgE to 3.8 major allergenic molecules per patient), while mono-sensitization was prominent and heterogeneous in other cities, such as Marseille (sIgE to Cup a 1: n = 55/80, 68.8%) and Messina (sIgE to Par j 2: n = 47/82, 57.3%). Co-sensitization to perennial allergens, as well as allergic comorbidities also broadly varied between study centers. CONCLUSIONS In Southern European countries, pollen allergy is heterogeneous in terms of sensitization profiles and clinical manifestations. Despite the complexity, a unique molecular, multiplex, and customized in-vitro IgE test detected relevant sensitization in all study centers. Nevertheless, this geographical diversity in pollen allergic patients imposes localized clinical guidelines and study protocols for clinical trials of SAR in this climatically complex region.

Abstract
BACKGROUND: Bedaquiline (BDQ) is widely used in the treatment of rifampicin-resistant TB (RR-TB). However, resistance to BDQ is now emerging. There are no standardised regimens for BDQ-resistant TB. This study aims to share experience in managing primary BDQ-resistant TB.METHODS: We performed a retrospective study of patients treated for RR-TB in Karakalpakstan, Uzbekistan, from January 2017 to March 2022. We identified patients with resistance to BDQ with no history of BDQ exposure. We describe baseline characteristics, treatment and follow-up of these patients.RESULTS: Twelve of the 1,930 patients (0.6%) had baseline samples resistant to BDQ with no history of BDQ exposure, 75% (9/12) of whom had been previously treated for TB. Ten (83.3%) were resistant to fluoroquinolones; respectively 66% and 50% had culture conversion by Month 3 and Month 6. The interim treatment outcomes were as follows: unfavourable treatment outcomes (3/12, 25%), favourable outcomes (2/12, 17%); the remaining seven (58%) were continuing treatment.CONCLUSIONS: A large proportion of the cases had previously been treated for TB and had TB resistant to quinolone. Both patients who had not experienced culture conversion by Month 3 had an unfavourable treatment outcome. Therefore, we recommend monthly monitoring of culture status for patients on treatment regimens for BDQ resistance.

Social and Structural Influences on Multiracial Identification and Health: a Public Health Mandate to Precisely Measure, Theorize, and Better Understand Multiracial Populations. J Racial Ethn Health Disparities 2023; 10:427-445.

Abstract
There is a growing group of adolescents and young adults in the USA who identify as multiracial. However, very little research, especially health research, focuses on understanding multiracial identification and health and behavioral outcomes for multiracial populations in comparison to their single-race counterparts. Understanding the intersectional influences on this identification process is critical to updating the literature on racial and ethnic identity and health with more accurate identifications and categories. It is especially critical that there is an explicit focus on understanding the impact of structural racism and discrimination when studying the process of racial identification and the impact on health. This review takes an interdisciplinary approach relying on a review of multiple research literatures: the historical literature on race, racism and categorization, psychological and adolescent medicine literatures on adolescent development, the sociological literature on racial and ethnic identification, and the limited public health research beginning to disentangle multiracial health outcomes. An empirically testable conceptual framework is offered to frame the organization of this review-demonstrating the multiple spheres of influence on racial and ethnic identification and the implication for health outcomes.

Abstract
BackgroundNonlinear associations in rheumatoid arthritis (RA) prevalence and sociodemographic indices suggest social determinants of health affect RA.1 RA screening tools have lower sensitivity and specificity for Hispanic/Latinx individuals compared with white individuals (77% vs 85% sensitivity and 45% vs 87% specificity).2 Hispanic/Latinx people also present to physicians later and with more severe RA.3 There is little research in this population to explain these differences or how they can be addressed. Because it is known the Hispanic/Latinx population has lower English-language proficiency, we hypothesized this is in part because of the lack of validated Spanish-language educational materials and research tools for RA.ObjectivesTo validate a Spanish-language patient-provider questionnaire (PPQ) for Hispanic/Latinx patients with RA that had previously been validated as concordant for primary care visits in Sweden.4To understand if rheumatologist and patient assessments for Hispanic/Latinx people with RA are concordant when using a Spanish-language digital PPQ.To determine if a Spanish-language rheumatologist-completed PPQ could be a proxy for patient impressions in a prospective clinical study.MethodsA Spanish-language PPQ for RA was created by translating 9 of 13 questions previously validated in the Swedish study,4 and adding a question about treating to target specific to RA. The survey was made available on tablet devices in 4 rheumatology clinics in the U.S. and Puerto Rico. Clinic staff obtained patient consent and gathered demographic information to generate a unique confidential identifier code for each visit, which was inputted into surveys on tablet devices. After the visit ended the patient and rheumatologist were each given the PPQ coded for that visit to complete independently of one another. The PPQs were submitted electronically to a secure database in which the visit code was the only identifier recorded.ResultsAcross 114 clinical visits, 96.75% of possible answers were recorded and were almost invariably positive with scores of 5 (strongly agree; 88%), 4 (agree; 12%), or 3 (neither agree nor disagree; 0.09%). Physicians responded with 4 (agree) more often than patients (18% vs 6% of responses). Responses from both patient and physician were available for (96.64%) of answered questions. Within these paired answers, 80.67% were concordant (same answer from both patient and physician). Physicians answered 4 when patients answered 5 in 76.5% of discordant responses (different ratings from patient and physician). Most physician ratings of 4 came from 1 of the 4 physicians involved and only 12.5% of patients were responsible for 75% of the patient responses of 4.ConclusionHispanic/Latinx patients with RA and their rheumatologist rated their communication, goal setting, and relationships extremely positively, making it difficult to evaluate true concordance and not possible to use rheumatologist-completed PPQs as proxy for patient assessments. Notably, ratings were substantially different from what is typically seen on Likert scales, which normally skew positively but with a normal distribution. This finding may reflect social determinants of health or cultural differences such as a social-desirability bias toward positive statements about physician-patient interactions. Heterogeneity within the participants is also a plausible explanation, considering that a distinct subset of respondents account for almost all responses below the 5 rating. Further research is needed to identify best practices for measuring treatment to target and patient-rheumatologist interactions in the Hispanic/Latinx population with RA.References[1]Safiri S, et al.

Abstract
The prevalence of allergic disorders drastically increased over the last 50 years that today they can be considered epidemic. At present, allergen-specific immunotherapy (AIT) is the only therapy targeting the underlying cause of allergic disorders, and its superior evidence is based on accumulated data from clinical trials and observational studies demonstrating efficacy and safety. However, several aspects remain unsolved, such as harmonization and standardization of manufacturing and quantification procedures across manufacturers, homogeneous reporting of strength, and also the establishment of international reference standards for many allergens. This article discusses the issues related to the measurement of major allergen content in AIT extracts, raising the question of whether comparison of products by different manufacturers are appropriate as basis to choose among the different AIT products. Allergen standardization in immunotherapy products is critical to ensure quality and thereby safety and efficacy. However, lack of harmonization in manufacturing process, allergen quantification (methodologies and references), national regulatory differences, clinical practice, and labeling shows that the comparison of AIT products solely based on major allergen amounts is not rationale and, in fact, impossible. Moreover, further inherent characteristics of products and their clinical use such as their state of extract modification, addition of adjuvant or adjuvant-system, route of administration (sublingual/subcutaneous) and cumulative dose as per posology (including the volume per administration) need to be taken into account, when rating the information given for a specific product. Finally, only convincing clinical data can serve as the product-specific evaluation, or the basis for cross-product comparability, for individual products.

Abstract
Abstract
Introduction
Coronavirus disease (COVID)-19 predominantly produces its effects through lung damage, but an important component of multi-organ dysfunction is cardiac involvement. We have few reports that inform about the behavior of echocardiographic images of patients with the most severe forms of the disease.
Purpose
The present work aims to identify prognostic markers for 60-day mortality in patients hospitalized in intensive care based on echocardiographic findings.
Methodology
A single-center retrospective cohort was conducted. Hospitalized patients were included in one of the nine intensive care units for COVID-19 confirmed by RT-PCR from May to October 2020. Patients with previous conditions that determined a limitation of the therapeutic effort, those who died before 24 hours and pregnant women were excluded. Portable echocardiograms were performed by two expert cardiologists following the recommendations for isolation and personal protection. The time to death was evaluated as outcome. A Cox proportional hazards model was constructed, HR and 95% confidence intervals with their p values. The study was approved by the institutional ethics committee.
Results
Of 326 patients included, 153 patients had an echocardiogram. The mean age was 60.7 years, 47 (30.7%) were female and 67 (44.7%) had positive troponin. 91 patients (59.5%) not survive, the mean long of stay was 8.4 (SD: 4.2) days. 111 (72.5%) had shock, 128 (83.7%) severe ARDS (PaO2 / FiO2 <100 mmHg), 142 (92.8%) required invasive ventilatory support, and 86 (56.2%) acute kidney injury. 27 (17.6%) patients had acute pulmonary embolism, 16 (10.4%) acute myocardial infarction and 9 (5.9%) myocarditis. The mean right ventricular ejection fraction was 37%, TAPSE was decreased in 16 cases (10.4%). 41 cases (26.8%) had right diastolic dysfunction. 34/48 (71%) cases had pulmonary hypertension. The average LVEF was 59.3% and 74 (48.4%) had some left ventricular diastolic dysfunction. 12 (7.8%) had left ventricular segmental wall motion abnormality and 16 (10.4%) had pericardial effusion. Univariate analysis identified TAPSE, PSAP, acute cor pulmonale and right ventricular dilatation as variables related to the outcome of mortality. The multivariate Cox model (Table 2) documented that acute cor pulmonale with a HR of 12.8 (95% CI 3.51 - 46.63, p<0.001) and right ventricular dilation with a HR of 4, 87 (95% CI 1.36–17.46, P 0.016) were associated with mortality.
Conclusions
In patients hospitalized in the intensive care unit for COVID-19, acute cor pulmonale and right ventricular dilatation behaved as independent predictors of in-hospital death.

Abstract
Abstract
Introduction
Coronavirus disease (COVID) - 19 presents with periodic outbreaks with a large number of critical cases that overwhelm the health system. One of the objectives of screening and management is to have markers that can efficiently stratify the individual risk of experiencing adverse results. High-sensitivity troponin has been proposed as one of the possible prognostic markers.
Purpose
To evaluate the prevalence of troponin elevation and its performance for predicting 60-days mortality in patients in ICU due to COVID - 19 in a Latin American population.
Methodology
A single-center retrospective cohort study was carried out in which patients in ICU for COVID-19 confirmed by RT-PC between May and December 2020 were included. Patients with previous conditions that determined a limitation of therapeutic effort and pregnant women were excluded. The outcome was 60-days mortality. Kaplan Meier survival curves were constructed, a ROC curve was generated for the prediction of death according to troponin levels by calculating the area under the curve. Finally, a Cox proportional hazards model was generated.
Results
296 patients were included, 110 (37.2%) female, the mean age was 60 (SD 14) years and the duration of symptoms before admission to the ICU was 8.4 (SD 4.2) days. 81.4% of the patients had at least one comorbidity, 117 (39.5%) had hypertension, 65 (21.9%) had diabetes, and 63 (21.3%) had chronic lung disease. Mortality occurred in 151 cases (51%), 225 (76%) presented shock, 242 (81.8%) severe ARDS (PaO2 / FiO2 <100 mmHg), 232 (78.4%) required invasive ventilatory support, and 153 (5.7%) developed acute kidney injury. The APACHE II average was 13.1 and SOFA 4.8. Troponin was positive in 118 (39.9%) patients, 29.6% of the survivors and 49.7% in non survivors. The AUC was 0.65 (95% CI 0.59–0.71) for predicting mortality (Figure 1). The Kaplan Meier curves are shown in Figure 2 with a p less than 0.001 by achieving the test. In the bivariate analysis, troponin obtained a HR of 1.94 and p<0.001, but in the multivariate model it was 1.39 (95% CI of 0.21–1.56) and p of 0.12.
Conclusions
High sensitivity troponin was found to be elevated in patients hospitalized for COVID-19 in the intensive care unit who died, with regular discrimination (AUC: 0.65), even though the univariate analysis by the Cox and Kaplan Meier methods showed association with 60-days mortality, this was not maintained in the multivariate model.

Abstract
BACKGROUND Peanut allergy has a rising prevalence in high-income countries, affecting 0.5%-1.4% of children. This study aimed to better understand peanut anaphylaxis in comparison to anaphylaxis to other food triggers in European children and adolescents. METHODS Data was sourced from the European Anaphylaxis Registry via an online questionnaire, after in-depth review of food-induced anaphylaxis cases in a tertiary paediatric allergy centre. RESULTS 3514 cases of food anaphylaxis were reported between July 2007 - March 2018, 56% in patients younger than 18 years. Peanut anaphylaxis was recorded in 459 children and adolescents (85% of all peanut anaphylaxis cases). Previous reactions (42% vs. 38%; p = .001), asthma comorbidity (47% vs. 35%; p < .001), relevant cofactors (29% vs. 22%; p = .004) and biphasic reactions (10% vs. 4%; p = .001) were more commonly reported in peanut anaphylaxis. Most cases were labelled as severe anaphylaxis (Ring&Messmer grade III 65% vs. 56% and grade IV 1.1% vs. 0.9%; p = .001). Self-administration of intramuscular adrenaline was low (17% vs. 15%), professional adrenaline administration was higher in non-peanut food anaphylaxis (34% vs. 26%; p = .003). Hospitalization was higher for peanut anaphylaxis (67% vs. 54%; p = .004). CONCLUSIONS The European Anaphylaxis Registry data confirmed peanut as one of the major causes of severe, potentially life-threatening allergic reactions in European children, with some characteristic features e.g., presence of asthma comorbidity and increased rate of biphasic reactions. Usage of intramuscular adrenaline as first-line treatment is low and needs to be improved. The Registry, designed as the largest database on anaphylaxis, allows continuous assessment of this condition.

Abstract
Polygenic inheritance plays a central role in Parkinson disease (PD). A priority in elucidating PD etiology lies in defining the biological basis of genetic risk. Unraveling how risk leads to disruption will yield disease-modifying therapeutic targets that may be effective. Here, we utilized a high-throughput and hypothesis-free approach to determine biological processes underlying PD using the largest currently available cohorts of genetic and gene expression data from International Parkinson's Disease Genetics Consortium (IPDGC) and the Accelerating Medicines Partnership-Parkinson's disease initiative (AMP-PD), among other sources. We applied large-scale gene-set specific polygenic risk score (PRS) analyses to assess the role of common variation on PD risk focusing on publicly annotated gene sets representative of curated pathways. We nominated specific molecular sub-processes underlying protein misfolding and aggregation, post-translational protein modification, immune response, membrane and intracellular trafficking, lipid and vitamin metabolism, synaptic transmission, endosomal-lysosomal dysfunction, chromatin remodeling and apoptosis mediated by caspases among the main contributors to PD etiology. We assessed the impact of rare variation on PD risk in an independent cohort of whole-genome sequencing data and found evidence for a burden of rare damaging alleles in a range of processes, including neuronal transmission-related pathways and immune response. We explored enrichment linked to expression cell specificity patterns using single-cell gene expression data and demonstrated a significant risk pattern for dopaminergic neurons, serotonergic neurons, hypothalamic GABAergic neurons, and neural progenitors. Subsequently, we created a novel way of building de novo pathways by constructing a network expression community map using transcriptomic data derived from the blood of PD patients, which revealed functional enrichment in inflammatory signaling pathways, cell death machinery related processes, and dysregulation of mitochondrial homeostasis. Our analyses highlight several specific promising pathways and genes for functional prioritization and provide a cellular context in which such work should be done.

Abstract
Coastal acidification in southeastern U.S. estuaries and coastal waters is influenced by biological activity, run-off from the land, and increasing carbon dioxide in the atmosphere. Acidification can negatively impact coastal resources such as shellfish, finfish, and coral reefs, and the communities that rely on them. Organismal responses for species located in the U.S. Southeast document large negative impacts of acidification, especially in larval stages. For example, the toxicity of pesticides increases under acidified conditions and the combination of acidification and low oxygen has profoundly negative influences on genes regulating oxygen consumption. In corals, the rate of calcification decreases with acidification and processes such as wound recovery, reproduction, and recruitment are negatively impacted. Minimizing the changes in global ocean chemistry will ultimately depend on the reduction of carbon dioxide emissions, but adaptation to these changes and mitigation of the local stressors that exacerbate global acidification can be addressed locally. The evolution of our knowledge of acidification, from basic understanding of the problem to the emergence of applied research and monitoring, has been facilitated by the development of regional Coastal Acidification Networks (CANs) across the United States. This synthesis is a product of the Southeast Coastal and Ocean Acidification Network (SOCAN). SOCAN was established to better understand acidification in the coastal waters of the U.S. Southeast and to foster communication among scientists, resource managers, businesses, and governments in the region. Here we review acidification issues in the U.S. Southeast, including the regional mechanisms of acidification and their potential impacts on biological resources and coastal communities. We recommend research and monitoring priorities and discuss the role SOCAN has in advancing acidification research and mitigation of and adaptation to these changes.

Abstract
BACKGROUND We report the results of International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2012 to December 2017 in 523 intensive care units (ICUs) in 45 countries from Latin America, Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific. METHODS During the 6-year study period, prospective data from 532,483 ICU patients hospitalized in 242 hospitals, for an aggregate of 2,197,304 patient days, were collected through the INICC Surveillance Online System (ISOS). The Centers for Disease Control and Prevention-National Healthcare Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI) were applied. RESULTS Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAI rates were higher in the INICC ICUs: in the medical-surgical ICUs, the pooled central line-associated bloodstream infection rate was higher (5.05 vs 0.8 per 1,000 central line-days); the ventilator-associated pneumonia rate was also higher (14.1 vs 0.9 per 1,000 ventilator-days,), as well as the rate of catheter-associated urinary tract infection (5.1 vs 1.7 per 1,000 catheter-days). From blood cultures samples, frequencies of resistance, such as of Pseudomonas aeruginosa to piperacillin-tazobactam (33.0% vs 18.3%), were also higher. CONCLUSIONS Despite a significant trend toward the reduction in INICC ICUs, DA-HAI rates are still much higher compared with CDC-NHSN's ICUs representing the developed world. It is INICC's main goal to provide basic and cost-effective resources, through the INICC Surveillance Online System to tackle the burden of DA-HAIs effectively.

Abstract
BACKGROUND AND PURPOSE The NeVa™ (Vesalio, Nashville, Tennessee) thrombectomy device is a CE-approved novel hybrid-cell stent retriever with offset enlarged openings coupled with functional zones and a closed distal end. The device was designed to incorporate and trap resistant emboli. The purpose was to determine the safety and efficacy of the NeVa™ stent. METHODS Prospective data was collected on the first thirty consecutive patients treated at four stroke centers with NeVa™ as first line treatment between December 2017 and May 2018. Clinical outcome measures included re-perfusion scores after each pass, complications (per-procedural complications, device related adverse events, all intracerebral hemorrhage (ICH) and symptomatic ICH (sICH) on follow up imaging), 24 hour NIHSS, mRS at discharge and 90 days. Baseline data as well as treatment parameters were documented. RESULTS Mean presenting NIHSS was 16. Sites of primary occlusion were 10 ICA, 16 M1-MCA, 3 M2-MCA and one basilar. There were five tandem occlusions. Reperfusion outcomes after each NeVa pass; TICI ≥ 2b after first pass 63%, after 1 or 2 passes 83%, after 1 to 3 passes 90%. TICI 2c-3 after first pass 47%, after 1-2 passes 57%, after 1-3 passes 60%. TICI ≥ 2b after final pass 93%; TICI 2c-3, 63%. There were no device related serious averse events and no sICH. Clot material was partially or completely incorporated into the device after 70% passes. The mean 24 hour NIHSS was 7 and the 90 day mRS was 0-2 in 53%. CONCLUSIONS The NeVa™ device demonstrated a high rate of first pass complete reperfusion effect, a good safety profile and favorable 90 day clinical outcomes in this initial clinical experience.

Abstract
UNLABELLED By the end of 2018, 42 years after the landing of the two Viking seismometers on Mars, InSight will deploy onto Mars' surface the SEIS (Seismic Experiment for Internal Structure) instrument; a six-axes seismometer equipped with both a long-period three-axes Very Broad Band (VBB) instrument and a three-axes short-period (SP) instrument. These six sensors will cover a broad range of the seismic bandwidth, from 0.01 Hz to 50 Hz, with possible extension to longer periods. Data will be transmitted in the form of three continuous VBB components at 2 sample per second (sps), an estimation of the short period energy content from the SP at 1 sps and a continuous compound VBB/SP vertical axis at 10 sps. The continuous streams will be augmented by requested event data with sample rates from 20 to 100 sps. SEIS will improve upon the existing resolution of Viking's Mars seismic monitoring by a factor of ∼ 2500 at 1 Hz and ∼ 200 000 at 0.1 Hz. An additional major improvement is that, contrary to Viking, the seismometers will be deployed via a robotic arm directly onto Mars' surface and will be protected against temperature and wind by highly efficient thermal and wind shielding. Based on existing knowledge of Mars, it is reasonable to infer a moment magnitude detection threshold of M w ∼ 3 at 40 ∘ epicentral distance and a potential to detect several tens of quakes and about five impacts per year. In this paper, we first describe the science goals of the experiment and the rationale used to define its requirements. We then provide a detailed description of the hardware, from the sensors to the deployment system and associated performance, including transfer functions of the seismic sensors and temperature sensors. We conclude by describing the experiment ground segment, including data processing services, outreach and education networks and provide a description of the format to be used for future data distribution.

Abstract
AIM Late-onset Alzheimer's disease (LOAD) accounts for 95% of all Alzheimer's cases and is genetically complex in nature. Overlapping clinical and neuropathological features between AD, FTD and Parkinson's disease highlight the potential role of genetic pleiotropy across diseases. Recent genome-wide association studies (GWASs) have uncovered 20 new loci for AD risk; however, these exhibit small effect sizes. Using NGS, here we perform association analyses using exome-wide and candidate-gene-driven approaches. METHODS Whole-exome sequencing was performed on 132 AD cases and 53 control samples. Exome-wide single-variant association and gene burden tests were performed for 76 640 nonsingleton variants. Samples were also screened for known causative mutations in familial genes in AD and other dementias. Single-variant association and burden analysis was also carried out on variants in known AD and other neurological dementia genes. RESULTS Tentative single-variant and burden associations were seen in several genes with kinase and protease activity. Exome-wide burden analysis also revealed significant burden of variants in PILRA (P = 3.4 × 10-5 ), which has previously been linked to AD via GWAS, hit ZCWPW1. Screening for causative mutations in familial AD and other dementia genes revealed no pathogenic variants. Variants identified in ABCA7, SLC24A4, CD33 and LRRK2 were nominally associated with disease (P < 0.05) but did not withstand correction for multiple testing. APOE (P = 0.02) and CLU (P = 0.04) variants showed significant burden on AD. CONCLUSIONS In addition, polygenic risk scores (PRS) were able to distinguish between cases and controls with 83.8% accuracy using 3268 variants, sex, age at death and APOE ε4 and ε2 status as predictors.

Abstract
BACKGROUND Scottish Terriers have a high incidence of juvenile onset hereditary ataxia primarily affecting the Purkinje neuron of the cerebellar cortex and causing slowly progressive cerebellar dysfunction. OBJECTIVE To identify chromosomal regions associated with hereditary ataxia in Scottish Terriers. ANIMALS One hundred and fifty-three Scottish Terriers were recruited through the Scottish Terrier Club of America. MATERIALS AND METHODS Prospective study. Dogs were classified as affected if they had slowly progressive cerebellar signs. When possible, magnetic resonance imaging and histopathological evaluation of the brain were completed as diagnostic aids. To identify genomic regions connected with the disease, genome-wide mapping was performed using both linkage- and association-based approaches. Pedigree evaluation and homozygosity mapping were also performed to examine mode of inheritance and to investigate the region of interest, respectively. RESULTS Linkage and genome-wide association studies in a cohort of Scottish Terriers both identified a region on CFA X strongly associated with the disease trait. Homozygosity mapping revealed a 4 Mb region of interest. Pedigree evaluation failed to identify the possible mode of inheritance due to the lack of complete litter information. CONCLUSION AND CLINICAL IMPORTANCE This finding suggests that further genetic investigation of the potential region of interest on CFA X should be considered in order to identify the causal mutation as well as develop a genetic test to eliminate the disease from this breed.

Abstract
HIV-associated neurocognitive disorders (HAND) may include neurological disorders of various severities such as AIDS dementia complex (ADC) also known as HIV dementia and HIV-associated dementia (HAD), HIV encephalopathy, and Mild Neurocognitive Disorder (MND). As it seems HIV-associated neurocognitive disorders are associated with a metabolic encephalopathy induced by HIV infection and fueled by immune activation of macrophages and microglia. Despite of a group, evidences have described presence of cognitive alterations in HIV patients at different stages of HIV infection so far; little is known about the neurocognitive state of patients at very early stages of HIV infection. Here, we explored the neurocognitive profile of a group of cases of HIV patients at very early stages of HIV infection. We have analyzed of three groups of subjects, thus, we have studied a group of patients with early HIV infection, a healthy control group and a group of patients with mild cognitive impairment due to neurodegenerative causes. Our results suggested that cognitive processes are sensitive to very early neuropathological changes in HIV infection. Noteworthy, our results also showed that neurocognitive profile of HIV patients differs from those cognitive alterations in patients with mild cognitive disorders associated to primary neurodegeneration. Together, our results point out that HIV infection generates neural changes even at early stages of infection. Furthermore, our results highlight the importance of a deep neurocognitive exploration at very early stages of HIV infection as this approach allow improve the accompaniment, clinical attachment and interventions.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Chronic airway inflammation provides a unique environment for B cell activation and antibody production. Clin Exp Allergy 2017; 47:457-466.

Abstract
BACKGROUND B cells play many roles in health and disease. However, little is known about the mechanisms that drive B cell responses in the airways, especially in humans. Chronic rhinosinusitis (CRS) is an inflammatory disease of the upper airways that affects 10% of Europeans and Americans. A subset of CRS patients develop nasal polyps (NPs), which are characterized by type 2 inflammation, eosinophils and group 2 innate lymphoid cells (ILC2s). We have reported that NP contain elevated levels of B cells and antibodies, making NP an ideal system for studying B cells in the airways. OBJECTIVE We sought to determine the mechanisms that drive B cell activation and antibody production during chronic airway inflammation. METHODS We analysed B cells from NP or tonsil, or after ILC2 coculture, by flow cytometry. Antibody production from tissue was measured using Luminex assays and the frequency of antibody-secreting cells by ELISpot. Formation of B cell clusters was assessed using immunohistochemistry. Expression of genes associated with B cell activation and class switch recombination was measured by qRT-PCR. RESULTS NP contained significantly elevated frequencies of plasmablasts, especially those that expressed the extrafollicular marker Epstein-Barr virus-induced protein 2 (EBI2), but significantly fewer germinal centre (GC) B cells compared with tonsil. Antibody production and the frequency of antibody-secreting cells were significantly elevated in NP, and there was evidence for local class switch recombination in NP. Finally, ILC2s directly induced EBI2 expression on B cells in vitro. CONCLUSIONS AND CLINICAL RELEVANCE Our data suggest there is a unique B cell activation environment within NP that is distinct from classic GC-mediated mechanisms. We show for the first time that ILC2s directly induce EBI2 expression on B cells, indicating that ILC2s may play an important role in B cell responses. B cell-targeted therapies may provide new treatment options for CRSwNP.

Abstract
Los bovinos criollos presentan características adaptativas de importancia. Se ha propuesto que el desarrollo y/o progresión de la leucosis bovina tiene bases genéticas. En el presente trabajo se estudió la dinámica del virus de la leucosis bovina en el ganado criollo Hartón del Valle en condiciones de infección natural. En 93 animales Hartón del Valle (HV), 30 Lucerna (LUC) y 30 Holstein (HOL) se evaluó la presencia del VLB por PCR-anidada, el desarrollo de linfocitosis por extendido en placa, los títulos de anticuerpos usando ELISA y la carga proviral mediante PCR en tiempo real, en tres muestreos durante un año. Se estimaron los porcentajes de animales infectados y se realizaron pruebas de independencia entre las variables evaluadas. Se encontró un efecto racial significativo sobre el desarrollo de la leucosis bovina, los animales de la raza Hartón presentaron menor tasa de infección del VLB (38,3%), desarrollaron menos linfocitosis persistente (15%), tuvieron mayores títulos de anticuerpos contra el virus (97,6) y mantuvieron la carga proviral más baja (663828 copias/ng de ADN) que las razas Lucerna y Holstein. Los datos aquí presentados pueden ser utilizados en programas de erradicación y control de la enfermedad. Se concluye que el ganado criollo Hartón del Valle puede ser considerado un progresor lento de la leucosis bovina.

Gene transcripts associated with muscle strength: a CHARGE meta-analysis of 7,781 persons. Physiol Genomics 2016; 48:1-11.

Abstract
Lower muscle strength in midlife predicts disability and mortality in later life. Blood-borne factors, including growth differentiation factor 11 (GDF11), have been linked to muscle regeneration in animal models. We aimed to identify gene transcripts associated with muscle strength in adults. Meta-analysis of whole blood gene expression (overall 17,534 unique genes measured by microarray) and hand-grip strength in four independent cohorts (n = 7,781, ages: 20-104 yr, weighted mean = 56), adjusted for age, sex, height, weight, and leukocyte subtypes. Separate analyses were performed in subsets (older/younger than 60, men/women). Expression levels of 221 genes were associated with strength after adjustment for cofactors and for multiple statistical testing, including ALAS2 (rate-limiting enzyme in heme synthesis), PRF1 (perforin, a cytotoxic protein associated with inflammation), IGF1R, and IGF2BP2 (both insulin like growth factor related). We identified statistical enrichment for hemoglobin biosynthesis, innate immune activation, and the stress response. Ten genes were associated only in younger individuals, four in men only and one in women only. For example, PIK3R2 (a negative regulator of PI3K/AKT growth pathway) was negatively associated with muscle strength in younger (<60 yr) individuals but not older (≥ 60 yr). We also show that 115 genes (52%) have not previously been linked to muscle in NCBI PubMed abstracts. This first large-scale transcriptome study of muscle strength in human adults confirmed associations with known pathways and provides new evidence for over half of the genes identified. There may be age- and sex-specific gene expression signatures in blood for muscle strength.

Pelvic MRI findings in relapsed prostate cancer after radical prostatectomy. Radiat Oncol 2015; 10:262.

Abstract
PURPOSE/OBJECTIVE Little is known about the clinical impact of using multiparametric MRI to plan early salvage radiotherapy after radical prostatectomy. We aimed to evaluate the incidence and location of recurrence based on pelvic multiparametric MRI findings and to identify clinical variables predictive of positive imaging results. MATERIALS AND METHODS We defined radiological criteria of local and lymph node malignancy and reviewed records and MRI studies of 70 patients with PSA recurrence after radical prostatectomy. We performed univariate and multivariate analysis to identify any association between clinical, pathological and treatment-related variables and imaging results. RESULTS Multiparametric MRI was positive in 33/70 patients. We found local and lymph node recurrence in 27 patients and 7 patients, respectively, with a median PSA value of 0.38 ng/ml. We found no statistically significant differences between patients with positive and negative multiparametric MRI for any variable. Shorter PSADT was associated with positive lymph nodes (median PSADT: 5.12 vs 12.70 months; p: 0.017). CONCLUSIONS Nearly half the patients had visible disease in multiparametric MRI despite low PSA. Positive lymph nodes incidence should be considered when planning salvage radiotherapy, particularly in patients with a short PSADT.

Brix refractometry in serum as a measure of failure of passive transfer compared to measured immunoglobulin G and total protein by refractometry in serum from dairy calves. Vet J 2015; 211:82-7. [PMID: 26993533 DOI: 10.1016/j.tvjl.2015.11.004] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2015] [Revised: 10/12/2015] [Accepted: 11/08/2015] [Indexed: 11/30/2022]
Abstract
A series of trials were conducted to evaluate Brix refractometry (Brix %) for the assessment of failure of passive transfer (FPT) in dairy calves compared to: (1) serum IgG (reference standard) when measured by radial immunodiffusion (RID) or a turbidometric immunoassay (TIA), and (2) serum total protein refractometry (STP). For the serum samples tested with TIA, STP, and Brix % (n = 310; Holstein calves), the median concentrations were 21.3 g/L IgG, 58 g/L STP, and 9.2%, respectively. For the serum samples tested with RID, STP and Brix % (n = 112; Jersey calves), the mean concentrations were 38 g/L IgG, 68 g/L STP, and 10.2%, respectively. For samples tested with only Brix % and STP (n = 265; Holstein calves), median STP and Brix % were 50 g/L STP and 8.5%, respectively. Correlations between Brix % and RID, and between Brix % and TIA were equal (r = 0.79, respectively). Brix % and STP were positively correlated (r = 0.99). Brix % estimated serum IgG concentrations determined by TIA and RID (r(2) = 0.63, 0.62, respectively). When FPT was defined as serum IgG < 10 g/L, Brix % ≤ 8.5% showed optimal sensitivity (100%) and specificity (89.2%) to predict FPT. At the same IgG cut-point, an STP value of ≤ 52 g/L showed a similar sensitivity (100%) and specificity (80.4%) to predict FPT. Brix refractometry predicted successful transfer of passive immunity in dairy calves, but further evaluation as a diagnostic tool for the diagnosis of FPT is warranted.
