Antigen (Ag)-specific T helper (Th)2cells play a central role in food allergy (FA) pathogenesis. Methods can be used to eliminate Ag-specific Th2 cells that are currently lacking. This study aims to eliminate the Ag-specific Th2 cells with a novel nanoparticle, the mEV (modified extracellular vesicles, that carry a chimeric antigen peptide, MHC II and caspase 3) in a murine FA model.

mEVs were generated by exposing dendritic cells (DC) to ovalbumin (OVA, a specific Ag) and recombinant caspase 3 (Casp3) in the culture overnight. Exosomes were purified from culture supernatant by the magnetic antibody approach. A murine FA model was developed with OVA as the specific Ag.

Purified mEVs had the molecular markers of extracellular vesicle, CD81, CD63, and CD9, cleaved Casp3 and MHC II/OVA complexes. mEVs specifically bound to the surface of Ag-specific CD4
T cells, induced Ag-specific CD4
T cell apoptosis both
and
as well as increased regulatory T cells in the intestinal tissues. Administration of mEV efficiently suppressed experimental FA.

mEVs carry Ag/MHC II complexes and Casp3, that can induce Ag-specific Th2 cell apoptosis. Administration of mEV can efficiently suppress experimental FA. The results suggest that the mEVs have the translational potential to be used in the treatment of FA and other allergic diseases.

Grass pollen allergy is the most widespread pollen allergy in the world. It still remains unknown in which aspects and in which extent symptoms from grass pollen allergy differ throughout the grass pollen season, although individual sensitization profiles of persons concerned are known for a long time.

The crowd-sourced symptom data of users of the Patient's Hayfever Diary were filtered for significant positive correlated users to grass pollen from Vienna (Austria) during the respective grass pollen seasons from 2014, 2015, and 2016. These symptom data were the foundation for 3 statistical approaches in order to examine different sections of the grass pollen season defined either by grass pollen data, phenology (grass species determination in the field), or symptom data itself.

Results from all 3 approaches are similar and come to the same major conclusion. The symptom peak of most users is observed in the second section of the grass pollen season (70%), followed by the first section (20%), and with thePhleum und Cynodon is documented for the last section of the grass pollen season. Crowd-sourced symptom data is the prerequisite for personal pollen information to consider the individuality of grass pollen allergy sufferers. Phenological monitoring is needed to provide information on specific grass taxa of importance to allergic persons.
Skin prick test (SPT) solutions and allergy vaccines (AVs) are crucial tools for diagnosis and therapy of allergies. It was the aim of this study to corroborate the content of products for diagnosis and treatment of dust mite allergies that are produced and sold in India.

SDS-PAGE, immunoblots and high-resolution mass spectrometric analysis was performed with 16 house dust mite (HDM) SPT solutions and AVs from 3 Indian manufacturers. Authority-approved European SPT solutions and in-house extracts were used as references.

From the 5 Indian
products, none contained proteins from this source. Instead, 1 sample contained
and human serum proteins, 4 products contained allergens from the storage mite
, allergens from the legume
(chickpea), and proteins from baker's yeast. From 4 Indian
labeled products, 2 contained human serum proteins and a limited number of
allergens. Two contained only
,
, and yeast proteins. In contrast, the European authority-approved
and
SPT solutions that weretable for dust mite allergy diagnosis and therapy, as they contain either no, or only a limited number of, HDM allergens. In addition, their use could lead to misdiagnosis since some of them contain allergens from other sources, including the storage mite Suidasia, chickpea, as well as baker's yeast. Further, their application might be harmful to patients, as some products contain large amounts of proteins of human origin. Analysis of European SPT solutions, on the other hand, confirmed their suitability for dust mite allergy diagnosis.Inborn errors of immunity (IEI) are a heterogeneous group of disorders, mainly resulting from mutations in genes associated with immunoregulation and immune host defense. These disorders are characterized by different combinations of recurrent infections, autoimmunity, inflammatory manifestations, lymphoproliferation, and malignancy. Interestingly, it has been increasingly observed that common allergic symptoms also can represent the expression of an underlying immunodeficiency and/or immune dysregulation. Very high IgE levels, peripheral or organ-specific hypereosinophilia, usually combined with a variety of atopic symptoms, may sometimes be the epiphenomenon of a monogenic disease. Therefore, allergists should be aware that severe and/or therapy-resistant atopic disorders might be the main clinical phenotype of some IEI. This could pave the way to target therapies, leading to better quality of life and improved survival in affected patients.
The aim of this
study was to evaluate the quality of four root canal obturation techniques using microcomputed tomography (micro-CT).

A total of 36 mandibular first premolars with mostly round canals were decoronated, then instrumented up to a size F3 rotary file, and dressed with an epoxy resin-based sealer. Subsequently, they were divided into 4 different groups (
= 9) based on the method of obturation lateral condensation using 0.02 tapered master cone (LC2), lateral condensation using 0.04 tapered master cone (LC4), matched single-cone technique (MS), and matched single cone-mediated ultrasonic activation (MSUA). All the teeth were scanned using micro-CT (resolution of 19 
m), and the percentage volume of voids was calculated. One-way analysis of variance and Tukey test were used to analyze the data (
= 0.05).

The total percentage volume of voids was significantly lower in the MSUA group compared to all other groups (
< 0.05). The total percentage volume of voids was significantly lower in the MS group compared to the LC4 (
< 0.001) and LC2 (
< 0.001) groups. However, there was no significant difference between the LC2 and LC4 groups (
< 0.65).

MSUA, significantly, showed the least root canal filling voids amongst all the obturation techniques studied. MSUA can be considered an effective method for the filling of the round root canals. In general, lateral condensation using either 0.02 or 0.04 tapered master cones had significantly the highest volume percentage of voids amongst the experimental groups.

The authors present a case of a 73-year-old female who presented with an acute large bowel obstruction. Abdominal computed tomography (CT) scan reveals a colorectal intussusception with a colonic distension upstream. Laparoscopy founds out a stenotic tumor on colorectal junction corresponding with an adenocarcinoma on histopathological exam. CT scan is the most specific diagnostic test for intussusception and is superior to ultrasonography and endoscopy and thus should be performed preferentially.Chondrosarcoma of the head and neck region is a rare disease, representing approximately 0.1% of all head and neck neoplasms. Parapharyngeal location is extremely rare and low-grade ones are even rarer. Surgery alone or followed by adjuvant radiotherapy is the treatment of choice. In this article, we report a case of a 67-year-old male with low-grade parapharyngeal chondrosarcoma who presented with a 3-month history of dysphagia. A cervical magnetic resonance imaging was performed that shows a well-defined mass located at the right parapharyngeal space, causing medial deviation of the mucosal space. Surgical resection of the tumor without neck dissection followed by adjuvant radiotherapy was undertaken with a favorable response. The purpose of this article is to add our case to the limited literature for good management of parapharyngeal chondrosarcomas.Pseudoaneurysms are rare complications in urological surgery. Typically, they would present with pain, haematuria or anaemia. We report a 60-year-old patient who was found to have a chronic pseudoaneurysm via a corona mortis vascular variant, 3 months after a robotic-assisted prostatectomy. Unlike other rare reports of delayed vascular complications after minimally invasive urological surgery, the patient was entirely asymptomatic.Apart from careful intraoperative dissection, a high index of suspicion and low threshold for imaging are also required in the follow up period. Percutaneous trans-arterial embolization is safe and effective in dealing with post-surgical pseudoaneurysms.The anomalies of the middle colic artery have rarely been reported and reviewed in literature. However, in case such anomalies are observed in clinical practice, surgery must still be performed safely. This report presents the case of a 78-years-old female who underwent ileocecal resection and hepatectomy due to ascending colon cancer with liver metastasis. Preoperative abdominal contrast-enhanced computed tomography showed an anomaly of the middle colic artery. Since such anomaly is extremely rare, preoperative evaluation of vascular structure is important for safely performing the surgery.Robert's uterus is a rare Müllerian malformation first characterized by a French gynecologist Héléne Robert in 1969. It represents an asymmetric division of the uterine cavity. A 45-year-old female patient presented with vaginal bleeding and vague abdominal pain for the course of 20 days, with a blood human chorionic gonadotropin level of 10331.00 mIU/mL, and a gestational sac in the right uterine horn without a fetal heart beat revealed by the ultrasound. Ectopic pregnancy in the right uterine horn seemed to be the most likely diagnosis. Laparoscopic and hysteroscopic attempts to terminate the pregnancy failed. A pelvic magnetic resonance imaging (MRI) performed after the surgery demonstrated Robert's uterus with pregnancy in the blind hemicavity. When a pregnancy sac has been revealed by an ultrasound but nothing has been found by a hysteroscopy, a possibility of uterine malformation should be considered. Radiologists and gynecologists should consider the application of MRI for diagnosis of congenital Müllerian uterine anomalies.Heterotaxy syndrome is a rare condition characterized by the abnormal arrangement of thoracoabdominal organs across the left-right axis of the body. It is generally classified as right and left atrial isomerism or asplenia and polysplenia syndrome, even though there are overlaps and uncertainties. The diagnosis of isomerism is typically made by echocardiography. However, multidetector computed tomography and MRI can help in obtaining detailed data on the morphology of the heart, great vessels, the anatomy of the internal organs, and their mutual arrangement that make an accurate diagnosis of heterotaxy syndrome. The authors present here the imaging findings of the heterotaxy polysplenia syndrome in a 21-year-old female with a complete endocardia cushion defect and a duplicated right renal vein.Joubert Syndrome is a rare autosomal recessive genetic disorder characterized by a distinctive midbrain-hindbrain malformation that gives the appearance of "the molar tooth sign" on axial magnetic resonance imaging (MRI). Mutations in the implicated genes, affect proteins integral to cellular structures like the primary cilium, basal bodies and centromeres, categorizing Joubert syndrome as a ciliopathy. The most common clinical manifestations include moderate to severe hypotonia in early infancy with ataxia developing later in life, abnormal breathing patterns (tachypnea, apnea), atypical eye movements, development delay and intellectual disabilities. Differential diagnosis between different ciliopathies is challenging due to the overlapping clinical features. French neurologist Marie Joubert was the first to describe the clinical findings in 1969 and later the disorder was named after her. In this report, we present the case of a newborn female patient who was admitted to the neonatal intensive care unit 12 hours after birth, presenting with dyspnea, cyanosis, signs of respiratory distress and seizures. During the course of her hospitalization elevated levels of urea and creatinine were detected and after an abdominal ultrasound and CT evaluation bilateral renal hyperplasia and polycystic kidney disease were discovered. An MRI of the head and neck revealed the presence of inferior vermis agenesis, with a medial crack in cerebellum, a partial dysgenesis of corpus callosum, an underlying and thicker cerebral peduncle, as well as the molar tooth sign suggesting a diagnosis of Joubert syndrome. The diagnosis was ultimately confirmed through molecular genetic testing. Through this case report, we hope to draw attention to this rare and elusive group of disorders and emphasize the value of a prompt diagnosis and a proactive and multidisciplinary approach in the management of these patients.Acute appendiceal diverticulitis is a difficult prospective diagnosis due to both its rarity and clinical overlap with other ileocecal diseases, such as acute appendicitis. Few preoperative radiological images of acute appendiceal diverticulitis have been presented in the literature. We report a case of acute appendiceal diverticulitis initially diagnosed with outpatient ultrasound and confirmed with contrast-enhanced computed tomography in an 85-year-old male who presented with right lower quadrant pain. Appendiceal diverticulitis is an often overlooked diagnosis, and given its association with appendiceal neoplasms and relatively high rate of perforation, it is important to consider this entity in patients with right lower quadrant pain in order to ensure that they are managed appropriately. The addition of high quality ultrasound and computed tomography (CT) images to the literature may heighten awareness of this rare condition and facilitate accurate preoperative diagnosis and management in these patients.Hemoptysis could be a life-threatening event, especially when the bleeding originates from the arterial pulmonary circulation. The main cause of this type of bleeding is pulmonary artery pseudoaneurysm (PAP), which can be managed by surgical, medical or minimally invasive techniques. This study reports the case of massive hemoptysis in a 75-year-old male patient, with a former history of lobectomy. The initial CT scan showed a giant PAP from a branch of the right middle lobar pulmonary artery, within the right lower lobectomy cavity. An endovascular approach was decided. Subsequently, the feeding artery of the PAP was embolized with detachable coils. The control CT scan showed a persistent opacification of the PAP. The embolization was then completed by injection of Onyx within coils packing, with a complete thrombose of the PAP on control CT scan. This report confirms the safety and efficacy profile of an endovascular approach to treat giant PAP, using a combination of coils and Onyx.Contrast-induced encephalopathy (CIE) is a well-known but rare complication following contrast media administration. Its nonspecific clinical manifestations hinder diagnosis, particularly in the pediatric population. The majority of cases are reversible, with clinical improvement and resolution of signs noted on diagnostic imaging. Here, we report the case of a 2-month-old patient with a history of complex cardiovascular disease who presented with a single episode of seizure after undergoing cardiac catheterization with nonionic iodinated contrast media. CIE is diagnosed based on the signs and symptoms exhibited by the patient and the findings on plain head computed tomography (CT) scan. Subsequently, the absence of neurological symptoms and disappearance of the imaging alterations on a control CT are documented.Dural arteriovenous fistula (dAVF) of the anterior cranial fossa is an aggressive entity with a high risk of intracranial hemorrhage. A 38-year-old woman presented to our institution with nasal obstruction and discharge. Computed tomography (CT) scans performed for suspected sinusitis revealed erosion of the crista galli predominantly on the left side. The frontal and ethmoidal sinuses adjacent to the crista galli were clear and did not communicate with the crista galli. Contrast computed tomography scans revealed ectatic vessels adjacent to the crista galli, coursing on the cortical surface. Cerebral angiography identified an anterior fossa dAVF supplied by the bilateral anterior and posterior ethmoidal arteries and drained by the dilated cortical veins. Based on these findings, we assumed that long-term compression by the pulsatile draining veins caused the erosion. The patient underwent successful microsurgical disconnection procedure of the dAVF with an uneventful postoperative course. We concluded that external erosion of the crista galli could be a sign of aggressive dAVF and requires careful examination.Herein is described the case of a 39-year-old female agronomist who was admitted to hospital after a syncopal episode. She had had fever, abdominal pain, nausea, and vomiting for the previous month. The patient showed signs of hypoperfusion, so a trans-thoracic echocardiography was done, demonstrating the presence of a cardiac tamponade. An emergency pericardiocentesis was performed, draining 500 ml of hematic content. Thoracic-abdominal computed tomography showed bilateral pleural effusion and also peritoneal effusion. Laboratory tests were compatible with an inflammatory situation with neutrophilic leukocytosis, alteration of hepatic function, and a plateau elevation of high-sensitivity troponin T. Colchicine was initiated but the evolution of the patient was torpid, making necessary the performance of a pericardial window due to an abrupt increase of pericardial effusion and echocardiographic signs of impending cardiac tamponade. Two chest tubes were inserted due to an increasing bilateral pleural effusion. Serology was positive for Leptospira spp. so doxycycline was initiated. She reported that she had inspected a rice-field the previous month. The patient presented a good response to the treatment, being discharged from hospital completely asymptomatic, with no pericardial effusion and practically resolved pleural effusions. She was evaluated again one month later, with no trace of effusions or symptoms. .Severe coronary calcification is a common cause for stent under-expansion, which is associated with an increased risk of stent thrombosis and restenosis. Presently the devices for treatment of under-expanded stent due to severe calcification are rotational atherectomy and high-pressure non-compliant balloons with the limitation of potential balloon rupture and perforation risk. We report on a series of seven successful treatments of chronically under-expanded stents due to severe calcification using shockwave coronary intravascular lithoplasty (IVL). Our report suggests that IVL is a feasible and safe tool for such chronically under-expanded stents. .The incidence of Dressler's syndrome after myocardial infarction (MI) has decreased in the reperfusion therapy era. Although guidelines recommend high-dose aspirin for treatment based on evidence from the pre-percutaneous coronary intervention (pre-PCI) era, bleeding and thrombotic concerns occurred upon aspirin administration after coronary stenting. A 69-year-old man with recent MI was admitted to our hospital. The patient presented with chest pain 1 week before admission. Electrocardiography revealed newly detected atrial fibrillation with no ST segment change. Urgent coronary angiography demonstrated a left circumflex artery occlusion. He underwent PCI, and a sirolimus-eluting stent was deployed. Aspirin, prasugrel, and apixaban were administered. However, hospital discharge was delayed because he developed heart failure during hospitalization. Twenty-three days after admission, he developed a fever of >39 °C. Electrocardiography showed anterior ST segment elevation, and echocardiography revealed a 6-mm pericardial effusion. We diagnosed the patient with Dressler's syndrome, and colchicine 0.5 mg/day + acetaminophen 2000 mg/day were administered. His condition clinically improved after treatment and he was discharged 32 days after admission. There was hesitation about administration of high-dose aspirin in a patient who has undergone recent coronary stenting. Combination therapy of colchicine and acetaminophen could be a treatment option for Dressler's syndrome. .A recent study revealed that recurrence of myocarditis occurs in a significant proportion of patients, but multiple recurrences of myocarditis have rarely been reported. The pathophysiology and best treatments for multiple recurrences of myocarditis remain unclear. A 60-year-old man presented to our emergency department with fever and chest pain. Physical examination, imaging, and laboratory findings were consistent with fulminant myocarditis. Paired titers confirmed adenovirus infection. The patient was treated with intra-aortic balloon pump and percutaneous cardiopulmonary support for 7 days and was discharged with near-normal electrocardiographic and echocardiographic findings on day 26. Over the subsequent 3 years, the patient experienced six episodes of recurrence of myocarditis with a progressive decrease in his ability to perform activities of daily living. At the time of his sixth recurrence, he died of ventricular fibrillation. Autopsy revealed mild enlargement of the left ventricle, extensive inflammatory cell infiltration, and mild interstitial fibrosis, suggesting left ventricle remodeling because of repetitive myocarditis. We have presented a case of multiple recurrences of myocarditis. This is the largest number of recurrences in a single patient reported to date. Further studies are needed to elucidate the underlying pathogenesis and best treatment of this condition. .A 41-year-old woman who had suffered an acute stroke underwent closure of a persistent patent foramen ovale (PFO) two months later. Eleven months after PFO closure the patient was hospitalized with signs of cardiogenic shock due to cardiac tamponade. Imaging studies showed a correct position of the left occluder disc, whereas the right atrial disc was in direct contact with the aortic root. At day 6, the patient underwent surgery via a minimally invasive route under cardiopulmonary bypass. The left atrial disc of the occluder was in a correct position. A too big right atrial disc together with a sharp angle misalignment toward the right atrial wall led to an erosion of the right atrial wall and of the wall of the aortic root. The occluder was explanted and the PFO closed by direct suture. Given the increasing number of procedures performed, serious and potentially life-threatening complications - even if rare - deserve special attention. Even though device oversizing was the most likely factor causing the erosion, other factors may play a role, as the patient used whole-body vibration starting three months before the incident. This could explain why the event happened as late as 11 months after the initial PFO closure. .A 63-year-old male with a medical history of uncorrected tetralogy of Fallot (TOF) presented to our hospital due to acute myocardial infarction (AMI). Emergency coronary angiography (CAG) was performed and it showed a severe thrombotic stenosis in the middle right coronary artery (RCA) and total thrombotic occlusion of the posterior descending branch of the RCA. Subsequently, percutaneous coronary artery intervention (PCI) under the guidance of intravascular ultrasound (IVUS) was performed. He was discharged on the 14th day in stable condition. Nine months after the PCI procedure, coronary computed tomography angiography was performed for follow-up, which revealed tetralogy of Fallot and complete resolution of the thrombus and ectasic coronary artery without stenosis. When he was 70 years old, he was transferred to our hospital because of recurrent AMI. As emergency CAG showed total thrombotic occlusion of the middle RCA, IVUS-guided PCI was performed. We experienced a very rare case of AMI in an adult patient with uncorrected TOF accompanied by coronary artery ectasia (CAE). To the best of our knowledge, this is the first case of AMI in an adult patient with uncorrected TOF accompanied by CAE. .Patients with Wolff-Parkinson-White (WPW) syndrome rarely have multiple accessory pathways (APs). Here, we present a case of a 21-year-old man with the manifest type B WPW syndrome who was experiencing multiple attacks of palpitations. The electrophysiological study revealed two APs located bilaterally the anterolateral tricuspid annulus and lateral mitral annulus. Atrial/ventricular extrastimulations induced two types of wide QRS tachycardia conducting via two APs in the clockwise and counterclockwise direction. These two APs were eliminated with careful mapping and catheter ablation. .Hyperhomocysteinemia has been established as a risk factor for cardiovascular events. This case of a 23-year-old male, presenting with acute coronary thrombosis and unremarkable past medical history, highlights the importance of measuring homocysteine levels in young individuals with acute coronary syndromes, especially those without conventional risk factors. .Flush occlusions of coronary arteries present with multiple challenges during primary percutaneous coronary intervention (PPCI). We describe a case of anterior ST-elevation myocardial infarction in cardiogenic shock, where it was not possible to identify the origin of left anterior descending artery (LAD) as it was flush occluded and initial attempts to place a coronary guidewire in the LAD during PPCI were unsuccessful. After failed attempts with multiple guidewires, a combined pharmacological-mechanical approach resulted in successful timely revascularization and subsequent recovery of the patient. .In the late phase after Fontan surgery, organ dysfunction due to high central venous pressure (CVP) is a major clinical problem. We have described the cases of two patients with portosystemic shunts who exhibited hyperammonemia and high cardiac output associated with peripheral vasodilatation after Fontan surgery. A high CVP in these patients may have resulted in the formation of a portosystemic shunt. We performed coil embolization and balloon-occluded retrograde transvenous obliteration for each case. The possibility of a portosystemic shunt as a postoperative complication of Fontan surgery should always be considered. Early detection and therapeutic intervention seem necessary from the viewpoint of stabilizing the Fontan circulation and delaying the progression of liver disorder. .Biobanking as a quickly growing branch of personalised medicine has undergone enormous progress during last two decades. Nowadays it is a well developed and structured multidisciplinary field that reflects developments and advances of biomedical research based on principles of predictive, preventive and personalised medicine (PPPM/3PM). All these trends in PPPM progress have to be translated into practice and education of new generation of scientists and healthcare givers. The importance of biobanks for multitasking research, personalised treatment, and health care systems was emphasised by many scientists and health care experts. As biobanking carries multidisciplinary character currently including more professionals than ten-twenty years ago, new generation of professional biobankers is urgently needed. To create new generation of biobankers who are fully competent to answer more and more scientific and practical questions, new study programmes, novel university curricula, and topic-dedicated courses are es process of creating optimal biobanking education.
Several biologic agents have been approved for the treatment of asthma, chronic urticaria and atopic dermatitis. These therapeutic agents are especially useful for patients with severe or refractory symptoms. We present the real-life experience of four of the commonly used biologic agents in the United Arab Emirates.

In this retrospective observational study, we reviewed the demographic, clinical, laboratory and treatment parameters for all patients treated with biologic agents.

270 patients received biologics at our centre between May 2015 and December 2019 with a median age of 36.5 years. Omalizumab was the most prescribed agent (n=183, 67.8%) followed by dupilumab (n=54, 20%), benralizumab (n=22, 8.1%) and mepolizumab (n=11, 4.1%). Urticaria was the commonest treatment indication (n=148, 55%) followed by asthma (n=105, 39%) and atopic dermatitis (n=13, 5%). All chronic urticaria patients were treated with omalizumab and showed improvement in the mean urticaria control test score from 6.7±4.47 to 12.02±4.17, with a p-value of 0.001. Dupilumab was found to be the most commonly prescribed drug for asthma (37%), followed by omalizumab (32%), benralizumab (21%) and mepolizumab (10%). The mean Asthma control test score for all asthmatics combined increased from 17.06 ± 5.4 to 19.44 ± 5.6, with p-value 0.0012 with treatment; FeNO reduced from 60.02 ± 45.74 to 29.11 ± 27.92, with p-value 0.001 and mean FEV1 improved from 2.38L ± 0.8 to 2.67L ± 0.78, with p-value 0.045. Only 4 patients in the entire cohort reported adverse events.

Our study demonstrated that biological agents are a safe and effective treatment for atopic asthma, chronic urticaria and atopic dermatitis.

Chronic Obstructive Pulmonary Disease (COPD) is characterized by persistent and progressive airflow limitation generally caused by prolonged cigarette smoking. Ethnic differences have been reported regarding COPD risk from smoking. The purpose of this study was to compare COPD prevalence in Hispanic and Caucasian smokers in a real-world setting. We studied consecutive patients referred to the community-based pulmonary practice. Hispanic and Caucasian smokers were included in the study.

The clinical diagnosis of COPD was recorded from the chart. COPD was defined by PFT using GOLD criteria. Exclusion criteria were other ethnicities, non-smokers, and patients with a history of asthma /other pulmonary conditions. We reviewed a total of 1,313 consecutive PFTs of which 797 patients met our inclusion criteria.

The prevalence of COPD among Hispanics was found to be lower by both clinical diagnosis as well as by spirometry compared to Caucasians (41.6% vs 54.2%). In Hispanics, clinical diagnosis was 91% higher by PFT, whereas for Caucasians, it was 6% lower. The odds of developing COPD (diagnosed based on FEV
/FVC ratio <70%) in the Caucasians are 4.1 times higher than Hispanics (Odds Ratio 4.1; 95%CI 2.8-5.9). Hispanic smokers have a lower prevalence of COPD both by the clinical diagnosis as well as by PFT. There is a significant disconnection between clinical and PFT diagnosis of COPD in Hispanic patients.

The genetic basis of lower COPD risk and prevalence in Hispanics needs to be better understood. Spirometry threshold criteria for confirming a diagnosis of COPD may need to be modified based on ethnicity in clinical practice.

The significance of
in pulmonary secretions is unclear, and usually is regarded as colonization, not contributing to symptoms or disease. Yet, in our experience,
seemed associated with chronic sputum, mucus plugging, atelectasis, and poor outcome.

The aim of this study is to describe the clinical findings of patients with
in pulmonary (sputum or bronchoscopy) secretions and the significance of
.

Retrospective study of inpatients and outpatients referred for pulmonary consultation with
in pulmonary secretions. Clinical parameters and estimates of whether
was likely clinically significant, were determined.

82 inpatients and 11 outpatients were identified, of which 61 (66%) had atelectasis and 68 (73%) bronchoscopies. Of patients having bronchoscopies, 56 (82%) had mucus, and 43 (63%) mucus plugging. Of the inpatients death (or probable death) occurred in 43 (63%), 42 (98%) of which were from definite or probable respiratory failure, with 13 (31%) likely related to mucus plugging, 16 (38%) possibly from mucus plugging, 6 (14%) unknown, and 7 (17%) not due to mucus plugging.
was felt likely clinically significant in 57 patients (61%), uncertain significance in 23 (25%), and not significant in 13 (14%). All outpatients had exacerbations, including 7 (64%) within a year.

Patients requiring pulmonary consultation with

was likely clinically significant in most patients. Recommendations to consider
in pulmonary secretions as colonization should be reconsidered.
Patients requiring pulmonary consultation with Candida in pulmonary secretions often have chronic sputum production, exacerbations, mucus plugging, atelectasis, and death from respiratory failure. Candida was likely clinically significant in most patients. Recommendations to consider Candida in pulmonary secretions as colonization should be reconsidered.The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the coronavirus disease (COVID-19) pandemic, which has led scientists all over the world to push for the identification of novel therapies for COVID-19. The lack of a vaccine and specific treatment has led to a surge of novel therapies and their publicity in recent times. Under these unprecedented circumstances, a myriad of drugs used for other diseases is being evaluated and repositioned to treat COVID-19 (example- Remdesivir, Baricitinib). While multiple trials for potential drugs and vaccines are ongoing, and there are many unproven remedies with little or no supporting evidence. Presently, discussions are revolving around the use of multivitamins (Vitamin, C, D, A), minerals (selenium, zinc), probiotics, flavonoids, polyphenols, and herbal remedies (curcumin, artemisinin, herbal drinks). Our review delves further into the details of some of these controversial therapies for COVID-19.COVID-19 has been considered to be the most destructive pandemic ever happened in the history of mankind. The worldwide research community has put a tenacious effort to carry out research on the COVID-19 to analyse its impact on economic, medical and sociolgoical fields. They are trying to solve many crucial issues related to this disease and derive strategies to deal with this global pandemic. In this paper, we have analysed the trend, countries affected regionally and the variation of cases at the country level on COVID-19 dataset. We have used the Principal component analysis on the COVID-19 dataset variables to reduce the dimensionality and find the most significant variables. Further, we have unveiled the hidden community structure of countries by applying the unsupervised clustering approach, K-means. We have compared the results with the K-means method. The communities achieved after applying the PCA are more precise. The resulted communities can be beneficial to researchers, scientists, sociologists, different policy makers and managers of health sector.The Caribbean part of the Kingdom of the Netherlands consists of six islands Aruba, Bonaire, Curaçao, St. Maarten, St. Eustatius, and Saba. Because of their small size and relative remoteness, they face several economic and healthcare challenges, including limited access to genetics services. In this article, we provide an overview of the clinical and community genetics services that are available in the Dutch Caribbean. In particular, we describe our joint pediatric-genetics clinic with a visiting clinical geneticist that was established in 2011 to provide clinical genetics services for the pediatric population of the Dutch Caribbean.The sustainability agenda has evolved around a set of interconnected dilemmas regarding economic, social, and environmental goals. Progress has been made in establishing thresholds and targets that must be achieved to enable life to continue to thrive on the planet. However, much work remains to be done in articulating coherent theoretical frameworks that adequately describe the mechanisms through which sustainability outcomes are achieved. This paper reviews core concepts in the sustainability agenda to develop four propositions on integrated sustainability that collectively describe the underlying mechanisms of sustainable development. We then advance a framework for integrated sustainability and assess its viability through linear regression and principal components analysis of key selected indicators. The results provide preliminary evidence that countries with institutions that enable cooperation and regulate competition perform better in attaining integrated sustainability indicators. Our findings suggest that institutional design is important to sustainability outcomes and that further research into process-oriented mechanisms and institutional characteristics can yield substantial dividends in enabling effective sustainability policy.

Urban and rural development interacts through the flows of people, materials, energy, goods, capital, and information. Without building sound urban-rural linkages, achieving development in one area could compromise it in another area. Achieving sustainable development needs customized policy prioritization and implementation in both urban and rural areas. Much literature exists in the research field of urban-rural linkages, but little has been done via a comprehensive analysis from an interlinkage perspective in the context of the Sustainable Development Goals (SDGs). Sustainable Development Goal 11 on sustainable cities and several targets embedded under other Goals provides a good framework for analyzing the urban-rural linkages. This paper contributes to this novel research perspective using Ghana as a case. The study applied an integrated approach by combining the results from a solution-scanning exercise with an SDG iinclusion. An integrated approach that considers both the synergies and trade-offs of relevant solutions is critical for effective policymaking, specifically in developing countries.
Here we describe the development of a protein immunofluorescent assay for the detection of nuclear-localized androgen receptor variant 7 (AR-V7) protein within circulating tumor cells (CTCs) identified in patient blood samples. Used in the clinic, the test result serves as a validated biomarker of futility for patients with progressing metastatic castration-resistant prostate cancer (mCRPC) who are treated with androgen receptor targeted therapies (AATT) in whom nuclear-localized AR-V7 CTCs are identified and have received level 2A evidence in the 2019 National Cancer Center Network (NCCN) guidelines (v1.0).

Assay development was completed on the Epic Sciences rare cell detection platform using control cell lines of known AR-V7 status and clinical testing of mCRPC patient samples obtained at the decision point in management.

Using these samples, all assay parameters, scoring criteria, and clinical cutoffs for positivity were prospectively selected and locked. After assay lock, blinded clinical validation testing was initiated on multiple, independent, clinical cohorts as reported by Scher et al (JAMA Oncol. 2016;21441-1449; JAMA Oncol. 2018;41179-1186) and Armstrong et al (J Clin Oncol. 2019;371120-1129).

The association of pulmonary congestion assessed by lung ultrasound (LUS) and biomarkers-other than N-terminal pro-brain natriuretic peptide (NT-proBNP)-is uncertain.

We investigated the relationship between total B-line count by LUS and several biomarkers in outpatients with suspicion of heart failure (HF). Primary care patients with suspected new-onset nonacute HF were evaluated both with a 12-scan LUS protocol (8 anterolateral areas plus 4 lower posterior thoracic areas) and 11 inflammatory and cardiovascular biomarkers. A cardiologist blinded to LUS and biomarkers except NT-proBNP confirmed HF diagnosis. After log-transformation of biomarkers' concentrations, unadjusted and adjusted correlations were performed.

A total of 170 patients were included (age 76 ± 10 years, 67.6% women). HF diagnosis was confirmed in 38 (22.4%) patients. After adjustment by age, sex, body mass index, and renal function, total B-line sum significantly correlated with NT-proBNP (R = 0.29, p < 0.001), growth/differentiation factor-15 (GDF-15; R = 0.23, p = 0.003), high-sensitive Troponin T (hsTnT; R = 0.36, p < 0.001), soluble interleukin-1 receptor-like 1 (sST2; R = 0.29, p < 0.001), cancer antigen 125 (CA-125; R = 0.17, p = 0.03), high-sensitivity C-reactive protein (hsCRP; R = 0.20, p = 0.009), and interleukin (IL)-6 (R = 0.23, p = 0.003). In contrast, IL-33 (R = -0.01, p = 0.93), IL-1β (R = -0.10, p = 0.20), soluble neprilysin (sNEP; R = 0.09, p = 0.24), tumor necrosis factor-alpha (TNF-α; R = 0.07, p = 0.39), and TNF-α receptor superfamily member 1A (TNFRSF1A; R = 0.14, p = 0.07) did not.

Total B-line sum correlated significantly, although moderately, with congestion and several inflammation biomarkers. Unexpectedly, the highest correlation found was with hsTnT.

COVID-19 causes high mortality and long hospitalization periods. The aim of this study was to search for new early prognostic strategies accessible to most health care centers.

Laboratory results, demographic and clinical data from 500 patients with positive SARS-CoV-2 infection were included in our study. The data set was split into training and test set prior to generating different multivariate models considering the occurrence of death as the response variable. A final computational method called the BGM score was obtained by combining the previous models and is available as an interactive web application.

The logistic regression model comprising age, creatinine (CREA), D-dimer (DD), C-reactive protein (CRP), platelet count (PLT), and troponin I (TNI) showed a sensitivity of 47.3%, a specificity of 98.7%, a kappa of 0.56, and a balanced accuracy of 0.73. The CART classification tree yielded TNI, age, DD, and CRP as the most potent early predictors of mortality (sensitivity = 68.4%, specificity = 92.5%, kappa = 0.61, and balanced accuracy = 0.80). The artificial neural network including age, CREA, DD, CRP, PLT, and TNI yielded a sensitivity of 66.7%, a specificity of 92.3%, a kappa of 0.54, and a balanced accuracy of 0.79. Finally, the BGM score surpassed the prediction accuracy performance of the independent multivariate models, yielding a sensitivity of 73.7%, a specificity of 96.5%, a kappa of 0.74, and a balanced accuracy of 0.85.

The BGM score may support clinicians in managing COVID-19 patients and providing focused interventions to those with an increased risk of mortality.

Due to the continued presence of HPAI A(H5) viruses in wild birds and the environment,there is still a risk of avian influenza incursions with the potential further spread between establishments, primarily in areas with high poultry densities. As the currently circulating HPAI A(H5N8) virus cancause high mortality also in affected duck farms, mortality eventscan be seen as a good indicatorted human cases is assessed as very lowand the risk forpeople occupationally exposedpeople as low.Any human infections with avian influenza viruses are notifiablewithin 24 hoursthrough the Early Warning and Response System (EWRS) and the International Health Regulations (IHR) notification system.American mink and ferret are highly susceptible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), but no information is available for other mustelid species. SARS-CoV-2 spreads very efficiently within mink farms once introduced, by direct and indirect contact, high within-farm animal density increases the chance for transmission. Between-farm spread is likely to occur once SARS-CoV-2 is introduced, short distance between SARS-CoV-2 positive farms is a risk factor. As of 29 January 2021, SARS-CoV-2 virus has been reported in 400 mink farms in eight countries in the European Union. In most cases, the likely introduction of SARS-CoV-2 infection into farms was infected humans. Human health can be at risk by mink-related variant viruses, which can establish circulation in the community, but so far these have not shown to be more transmissible or causing more severe impact compared with other circulating SARS-CoV-2. Concerning animal health risk posed by SARS-CoV-2 infection the animal species that mution and results publicly shared.The additive tragacanth gum is intended to be used as a technological additive (category technological additive; functional groups emulsifier, stabiliser, thickener, gelling agent) for all animal species. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) assessed the data provided by the applicant in the technical dossier. During the course of the assessment, the need for additional information in order to be able to deliver an opinion on the safety and efficacy of this additive was identified and notified to the applicant. The information requested covered the characterisation and identification, the safety for the target species and the efficacy of the additive. The applicant has failed to provide the additional information. Therefore, considering the data provided in the original dossier and the absence of response from the applicant to the requests from EFSA, the FEEDAP Panel is not in a position to deliver an opinion on the safety and efficacy of the additive tragacanth gum as a technological additive for all animal species.Following a request from the European Commission, EFSA developed updated scientific guidance to assist applicants in the preparation of applications on smoke flavouring primary products. This guidance describes the scientific data to be included in the applications for the authorisation of new smoke flavouring primary products, as well as for the renewal or for the modification of existing authorisations, submitted respectively under Articles 7, 12 and 11 of Regulation (EC) No 2065/2003. Information to be provided in all applications relates to the characterisation of the primary product, including the description of the source materials, manufacturing process, chemical composition, specifications and stability; the proposed uses and use levels and the assessment of the dietary exposure; the safety data, including information on the genotoxic potential of the identified components and of the unidentified fraction of the primary product, toxicological data other than genotoxicity and information on the safety for the environment. For the toxicological studies a tiered approach is applied, for which the testing requirements, key issues and triggers are described. A description of the standard uncertainties relevant for the evaluation of primary products and how these are considered in the standardised risk assessment procedure is also included. The applicant should generate the data requested in each section to support the safety assessment of the smoke flavouring primary product. On the basis of the submitted data, EFSA will assess the safety of the primary product and conclude whether or not it presents risks to human health and to the environment under the proposed conditions of use.EFSA assessed the role of seropositive wild boar in African swine fever (ASF) persistence. Surveillance data from Estonia and Latvia investigated with a generalised equation method demonstrated a significantly slower decline in seroprevalence in adult animals compared with subadults. The seroprevalence in adults, taking more than 24 months to approach zero after the last detection of ASFV circulation, would be a poor indicator to demonstrate the absence of virus circulation. A narrative literature review updated the knowledge on the mortality rate, the duration of protective immunity and maternal antibodies and transmission parameters. In addition, parameters potentially leading to prolonged virus circulation (persistence) in wild boar populations were reviewed. A stochastic explicit model was used to evaluate the dynamics of virus prevalence, seroprevalence and the number of carcasses attributed to ASF. Secondly, the impact of four scenarios on the duration of ASF virus (ASFV) persistence was evaluated with the model, namely a (1) prolonged, lifelong infectious period, (2) reduction in the case-fatality rate and prolonged transient infectiousness; (3) change in duration of protective immunity and (4) change in the duration of protection from maternal antibodies.
