RESUMEN
Given asthma's large phenotypic diversity, the study was aimed to use specific biomarkers to characterize Allergic asthma (AA) and its severity. Blood was collected from 42 healthy controls (HCs) and 96 patients with AA. Biomarkers related to blood cell number and function: total leukocyte count (TLCs), neutrophil, lymphocyte, monocyte, eosinophil, basophil, neutrophil-to-lymphocyte ratio (NLR), immunoglobulin E (IgE), tryptase and eosinophilic cationic protein (ECP) as well as remodelling biomarkers (Matrix metalloproteinase (MMP-9), (MMP-16), Fibroblast growth factor (FGF-18) and (FGF-23) and alpha-skeletal muscle actin-1 (ACTa-1) were measured. Significant differences were observed in hematological parameters with higher levels of total leukocytes, eosinophil, and basophil counts in the AA group compared to HCs. The disease group also had significantly higher levels of several serum biomarkers (IgE, TPs, ECP, MMP-9, MMP-16, FGF-18, FGF-23, and ACTa-1) compared to HC. Forced expiratory volume 1 (FEV1) and forced vital capacity (FVC) had a strong negative correlation with ECP, IgE, and ACTa-1. FEV1 was negatively correlated with MMP-16 and tryptase. Patients with AA have higher levels of several biomarkers, such as MMP-9, MMP-16, FGF-18, FGF-23, IgE, tryptase, and ACTa-1. In addition, IgE, tryptase, ACTa-1, and MMP-16 are related to lung function impairment in AA. This indicates that measuring multiple biomarkers may be of value in the future when diagnosing and monitoring AA.

The prevalence of diabetes mellitus is growing globally and the management of diabetes is a critical issue for public health. This study aimed to analyze the concentration of different biomarkers in patients with type 2 diabetes mellitus (T2DM) without complication, T2DM patients with complication (T2DM+C), and compared to healthy controls (HC). For this aim, there were 164 participants: 59 T2DM, 60 T2DM+C, and 45 HC. Venous blood was collected and the levels of Hemoglobin A1C (HbA1C), fasting blood glucose, Interleukin-31 (IL-31), IL-35, glutamic acid decarboxylase antibody (GADA), developmental locus-1 (Del-1), fibroblast growth factor-9 (FGF-9) and FGF-18) and lipid profile (total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL) and triglyceride) were analyzed. Results showed that IL-31 was significantly higher in T2DM compared to HC (p<0.0001), and compared to T2DM+C (p<0.0001). IL-31 was significantly lower in T2DM+C than HC (p=0.009). The level of serum GADA was significantly elevated in T2DM compared to HC (p=0.0009), and T2DM+C (p=0.03). There was a significant correlation between (IL-31, IL-35, GADA, Del-1, FGF-9 and FGF-18). The duration of having diabetes was significantly longer in T2DM+C compared to T2DM (p<0.0001). However, there was no significant difference in the level of HBA1C% between T2DM+C and T2DM patients (p=0.98). In conclusion, there were significant differences in biomarker concentrations between all three groups. This indicates that the monitoring of multiple biomarkers may be of value in the controlling of T2DM in the future.

The objective of the current investigation was to investigate the diagnostic utility of the serum concentrations and mutational status of TGFß1, SMAD2, CTNNß1, and Wnt3a. and the expression levels of humanrelated genes in patients with non-small cell lung cancer (NSCLC). The serum concentrations were determined using the ELISA technique, and PCR for genotype variations of TGFß1, SMAD2, CTNNß1, and Wnt3a were examined using Sanger sequencing in tissue samples obtained from 93 patients with NSCLC and 84 healthy individuals for blood, and 20 Formalin Fixed Parafï¬n Embedded (FFPE) from normal samples dissected adjacent to the tumour. The findings of the current investigation indicate that individuals diagnosed with NSCLC exhibited significant elevation in the serum levels of CEA and CYFRA21-1, as well as TGFß1, SMAD2, CTNNß1, and Wnt3a. In total, 325 mutations in four trialled genes (243 mutations in TGFß1, 24 mutations in SMAD2,47 mutation Wnt3a and 11 mutations in CTNNß1) were identified in patients with NSCLC. Furthermore, all mutations were recorded in adenocarcinoma, not squamous and normal adjacent tumour cells. CYFRA21-1 and CEA are more significant between NSCLC and HC, gender, and NSCLC types (p<0.001). In detail, TGFß1 exhibited the highest rate of mutations among other genes and three types of genomic mutations. Elevated levels and genetic polymorphisms of TGFß1, SMAD2, CTNNß1, and Wnt3a may play crucial functions in the pathogenesis and angiogenesis of non-small cell lung cancer (NSCLC). These biomarkers might play a role in future immunologic response and pharmacologically targeted NSCLC therapy.

Objective: The hyperinflammatory response, caused by severe acute respiratory syndrome-2 (SARS-CoV-2), is the most common cause of death in patients with coronavirus disease 2019 (COVID-19). The etiopathogenesis of this illness is not fully understood. Macrophages appear to play a key part in COVID-19's pathogenic effects. Therefore, this study aims to examine serum inflammatory cytokines associated with the activation state of macrophages in COVID-19 patients and attempt to find accurate predictive markers for disease severity and mortality risk in hospital. Methods: 180 patients with COVID-19 and 90 healthy controls (HCs) participated in this study. Patients were divided into three different subgroups, mild (n=81), severe (n=60), and critical groups (n=39). Serum samples were collected and IL (Interleukin)-10, IL-23, tumor necrosis factor-alpha (TNF-α), interferon-gamma (IFN-γ), IL-17, monocyte chemoattractant protein-1 (MCP-1) and chemokine ligand 3 (CCL3) were determined by ELISA. In parallel, myeloperoxidase (MPO) and C-reactive protein (CRP) were measured using colorimetric and electrochemiluminescence methods, respectively. Data were collected, and their associations with disease progression and mortality were assessed using regression models and receiver operating characteristic (ROC) curves. Results: Compared to HCs, a significant increase in IL-23, IL-10, TNF-α, IFN-γ and MCP-1, were observed in COVID-19 patients. Serum levels of IL-23, IL-10, and TNF-α were significantly higher in COVID-19 patients with critical cases compared to mild and severe cases, and correlated positively with CRP level. However, non-significant changes were found in serum MPO and CCL3 among the studied groups. Moreover, significant positive association has been observed among increased IL-10, IL-23 and TNF-α in serum of COVID-19 patients. Furthermore, a binary logistic regression model was applied to predict death's independent factors. Results showed that IL-10 alone or in combination with IL23 and TNF-α are strongly linked with non-survivors in COVID-19 patients. Finally, ROC curve results uncovered that IL-10, IL-23 and TNF-α were excellent predictors for prognosing COVID-19. Conclusion: The elevations of IL-10, IL-23, and TNF-α levels were seen in severe and critical cases of COVID-19 patients and their elevations were linked to the in-hospital mortality of the disease. A prediction model shows that the determination of these cytokines upon admission is important and should be done on COVID-19 patients as a way of evaluating the prognosis of the disease. COVID-19 Patients with high IL-10, IL-23, and TNF-α on admission are more likely to experience a severe form of the disease; therefore, those patients should be cautionary monitored and treated.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is a devastating pandemic that causes disease with a variability in susceptibility and mortality based on variants of various clinical and demographic factors, including particular genes among populations. OBJECTIVES: Determine associations of demographic, clinical, laboratory, and single nucleotide polymorphisms in the ACE2, TMPRSS2, TNF-α, and IFN-γ genes to the incidence of infection and mortality in COVID-19 patients. DESIGN: Prospective cohort study SETTINGS: Various cities in the Kurdistan Region of Iraq. PATIENTS AND METHODS: This prospective cohort study compared laboratory markers (D-dimer, tumor necrosis factor-alpha [TNF-α], interferon-gamma [IFN-γ], C-reactive protein [CRP], lymphocyte and neutrophil counts) between COVID-19 patients and healthy controls. DNA was extracted from blood, and genotypes were done by Sanger sequencing. MAIN OUTCOME MEASURES: Single nucleotide polymorphisms of the ACE2, TMPRSS2, TNF-α, and IFN-γ genes and demographic characteristics and laboratory markers for predicting mortality in COVID-19. SAMPLE SIZE: 203 (153 COVID-19 patients, 50 health control subjects). RESULTS: Forty-eight (31.4%) of the COVID-19 patients died. Age over 40 and comorbidities were risk factors for mortality, but the strongest associations were with serum IFN-γ, the neutrophil-to-lymphocyte ratio (NLR), and serum TNF-α. The AA genotype and A allele of TMPRSS2 rs2070788 decreased while the GA genotype and A allele of TNF-α increased susceptibility to COVID-19. Patients with the GA genotype of TNF-α rs1800629 had shorter survival times (9.9 days) than those carrying the GG genotype (18.3 days) (P<.0001 by log-rank test). The GA genotype versus the GG genotype was associated with higher levels of serum TNF-α. The GA genotype increased mortality rates by up to 3.8 fold. The survival rate for COVID-19 patients carrying the IFN-γ rs2430561 TT genotype (58.5%) was lower than in patients with the TA and AA genotypes (80.3%). The TT genotype increased the risk of death (HR=3.664, P<.0001) and was linked to high serum IFN-γ production. Olfactory dysfunction was a predictor of survival among COVID-19 patients. CONCLUSIONS: Age older than 40, comorbidities, the NLR and particular genotypes for and the IFN-γ and TNF-α genes were risk factors for death. Larger studies in different populations must be conducted to validate the possible role of particular SNPs as genetic markers for disease severity and mortality in COVID-19 disease. LIMITATIONS: Small sample size. CONFLICT OF INTEREST: None.

RESUMEN
Purpose: Oxidative stress (OS) and inflammation are pivotal points in the pathophysiology of coronavirus disease-2019 (COVID-19). This study aims to use routine laboratory and oxidative stress/antioxidative biomarkers as predictors for the mortality of the disease. Patients and Methods: This prospective cohort study, made up of 120 COVID-19 patients from emergency units in Erbil, Duhok, Kirkuk, and Sulaymaniyah cities in Iraq, from May the 1st to May the 30th, 2021, and 60 healthy controls (HCs) (n = 60). The patients were re-categorized into mild (n = 54), severe (n = 40), and critical (n = 26) groups based on the clinical criteria. Following admission to the hospital, blood was directly collected for measuring routine laboratory biomarkers. Results: Neutrophils and neutrophil/lymphocyte ratio (NLR) were higher in the critical group, while lymphocytes were lower in the severe and critical groups compared to the mild group. The CRP, ferritin, and D-dimer values were more elevated in severe and critical cases than in mild COVID-19 cases. The levels of malondialdehyde (MDA), nitric oxide (NO), and copper were elevated, while the superoxide dismutase (SOD) activity level and total antioxidant capacity (TAC) level were lower. However, vitamin C, glutathione peroxidase (GPx), and catalase activity levels were not changed in the COVID-19 groups compared to the HCs. NO and ferritin were predictors of ICU hospitalization; D-dimer, MDA, and NLR were predictors of mortality. NO, and NLR were predictors of SpO2 depression. Moreover, NO, and copper have both good diagnostic values, their cutoffs were 39.01 and 11.93, respectively. Conclusion: There is an association between immune dysregulation and oxidative imbalance. The biomarkers, that could be considered as predictors for the severity and mortality of COVID-19, are the NLR, NO, ferritin, and D-dimer. The age equal to and older than 50 has a poor prognosis in the Kurdish population.
RESUMEN
Introduction: Biomarkers play a crucial role in evaluating the prognosis, diagnosis, and monitoring of non-small cell lung cancer (NSCLC). The aim of this study was to compare the levels of inflammatory and remodelling biomarkers among patients with NSCLC and healthy controls (HCs) and to investigate the correlation between these biomarkers. Material and methods: Blood samples were taken from 93 NSCLC and 84 HCs. Each sample was analysed for the inflammatory biomarkers transforming growth factor ß1 (TGF-ß1), mothers against decapentaplegic homolog 2 (SMAD2) and the remodelling biomarkers Wingless-related integration site (Wnt3a) and α-catenin (CTNN-ß1). Results: The patients with NSCLC had significantly higher levels of all the measured biomarkers. In the NSCLC patients, TGF-ß1 correlated significantly with SMAD2 (r = 0.34, p = 0.0008), Wnt3a (r = 0.328, p = 0.0013), and CTNN-ß1 levels (r = 0.30, p = 0.004). SMAD2 correlated significantly with CTNN-ß1 (r = 0.546, p = 0.0001) and Wnt3a (r = 0.598, p = 0.0001). CTNN-ß1 level also correlated with the level of Wnt3a (r = 0.61, p = 0.0001). No correlation was found between biomarkers and symptom scores. Discussion: In this study, patients with NSCLC had higher inflammatory and remodelling biomarker levels than HCs. In the NSCLC, there were significant associations between inflammatory and remodelling biomarkers. This indicates that measuring biomarkers could be valuable in the workup of NSCLC patients. Conclusions: Our investigation showed that inflammatory and remodelling biomarkers might play a role in future immunologic response and pharmacologically targeted NSCLC therapy.
RESUMEN
BACKGROUND/PURPOSE: The formation of white spot lesions (WSLs) around fixed orthodontic attachments is a common complication during and following fixed orthodontic treatment, marking the result of a successfully completed treatment. This double-blind, randomized clinical trial study aims to investigate the varying effects of nano-silver, chlorhexidine (CHX) or fluoride mouthwashes on WSLs. MATERIALS AND METHODS: Double-blind prospective randomized clinical trial, comprised of forty-two patients with mild to moderate crowding, were recruited for this study. Randomization and allocation to trial group were carried out by computer system in college of dentistry, university of Sulaimani from January 2020 to September 2020. The patients were divided into three groups (14 per group) according to the type of mouthwash used during the treatment (nano-silver, CHX or fluoride), using block randomization. The clinical examination for the presence of WSLs was recorded through visual examination of the upper and lower anterior teeth using the International Caries Detection and Assessment System (ICDAS II) score before bonding and at 30, 90 and 180 days after bonding of the upper and lower arches. RESULTS: The total number of patients was 42 (16 males and 26 females) with a mean age of 23.02⯱â¯3.841 (18-37) years old, distributed into three groups of 14 patients. There is significant difference in white spot lesions formation between the three groups; the mean of WSLs in nanosilver group is lower than CHX and fluoride group in 90 and 180 days of follow-up (Pâ¯<â¯0.05). CONCLUSION: Nano-silver mouthwash is more effective than CHX and fluoride mouthwash in reducing WSLs during orthodontic treatment.
RESUMEN
Allergic asthma (AA) is a complex disorder with heterogeneous features of airway hyperresponsiveness, inflammation, and remodeling. The increase of airway smooth muscle (ASM) mass is a fundamental component of bronchial remodeling in AA, yet the pathophysiological mechanisms and clinical outcomes associated with ASM modulation are still elusive. The objective of this study is to compare the expression level of ß-dystroglycan (ß-DG) in ASM in AA subjects and a healthy control group and to investigate the relationship between eosinophils and ß-DG in ASM in patients with AA. Thirteen AA patients and seven control subjects were analyzed for the ASM area and eosinophil cells. Bronchial biopsies were stained by ß-DG and eosinophil cationic protein (ECP) using immunohistochemistry. The proportion of ASM with ß-DG staining was greater in those with AA than in the healthy control group (mean (95% CI) (28.3% (23.8-32.7%) vs. 16.4% (14.1-18.5%), P < 0.0001). The number of ECP positive cells was higher in patients with AA than in the control group (4056 (3819-4296) vs. 466 (395-537) cells/mm2 P < 0.0001). In AA, the number of ECP positive cells was significantly correlated to the ß-DG expression in ASM (r = 0.77, P = 0.002). There is an increased ß-DG expression in ASM and a higher number of ECP positive cells in the bronchial biopsy of those with AA than those in the control group. The increased expression of ß-DG in ASM in AA subjects correlates with the number of eosinophils, suggesting a role for this cell in airway remodeling in AA.

This study investigated the in vivo antileukemic activity of palladium nanoparticles (Pd@W.tea-NPs) mediated by white tea extract in a murine model. The cell viability effect of Pd@W.tea-NPs, "blank" Pd nanoparticles, and white tea extract alone was determined in murine leukemia WEHI-3B cells and normal mouse fibroblasts (3T3 cells). Apoptotic and cell cycle arrest effects of Pd@W.tea-NPs in WEHI-3B cells were evaluated. The effects of Pd@W.tea-NPs administered orally to leukemic mice at 50 and 100 mg/kg daily over 28 days were evaluated. Pd@W.tea-NPs reduced the viability of WHEI-3B cells with IC50 7.55 µg/ml at 72 h. Blank Pd nanoparticles and white tea extract alone had smaller effects on WHEI-3B viability and on normal fibroblasts. Pd@W.tea-NPs increased the proportion of Annexin V-positive WHEI-3B cells and induced G2/M cell cycle arrest. Leukemic cells in the spleen were reduced by Pd@W.tea-NPs with an increase in Bax/Bcl-2 and cytochrome-C protein and mRNA levels indicating the activation of the mitochondrial apoptotic pathway. These effects replicated the effects of ATRA and were not observed using blank Pd nanoparticles. Pd@W.tea-NPs afford therapeutic efficacy against leukemia likely to pivot on activation of the mitochondrial pathway of apoptotic signaling and hence appear attractive potential candidates for development as a novel anticancer agent.
RESUMEN
Many types of research have distinctly addressed the efficacy of natural plant metabolites used for human consumption both in cell culture and preclinical animal model systems. However, these in vitro and in vivo effects have not been able to be translated for clinical use because of several factors such as inefficient systemic delivery and bioavailability of promising agents that significantly contribute to this disconnection. Over the past decades, extraordinary advances have been made successfully on the development of novel drug delivery systems for encapsulation of plant active metabolites including organic, inorganic and hybrid nanoparticles. The advanced formulas are confirmed to have extraordinary benefits over conventional and previously used systems in the manner of solubility, bioavailability, toxicity, pharmacological activity, stability, distribution, sustained delivery, and both physical and chemical degradation. The current review highlights the development of novel nanocarrier for plant active compounds, their method of preparation, type of active ingredients, and their biomedical applications.

BACKGROUND: The aim was to determine the level of inflammatory cytokines, eosinophil cationic protein and IgE in allergic rhinitis (AR) patients. SUBJECTS AND METHODS: Blood samples were taken from 88 AR patients and 88 healthy controls (HC). Each sample was analysed for eosinophil counts by flow cytometry, IgE by ECLIA, ECP, IL-17, and IL-33 by using ELISA test. RESULTS: There was no significant difference between AR patients and the control group in age and gender. Levels of eosinophils, IgE, ECP, IL-17, IL-33 and the total symptom scores were significantly higher in AR patients than the HC (P = 0.0001). Serum ECP correlated with IL-17 (P = 0.041, r = 0.42), IL-33 (P = 0.0001, r = 080), and IgE levels (P = 0.017, r = 0.45) in the R patients. There was no correlation between IL-17 and IL-33. There was a correlation between symptom scores and eosinophils (P = 0.026, r = 0.52), and IgE (P = 0.001, r = 0.60) in the patients. No correlation was observed between symptom scores and ECP, IL-17, and IL-33 in the AR patient. CONCLUSIONS: Patients with AR have significant higher serum levels of ECP, IL-17, and IL-33 than healthy controls. This indicates that these markers could be used to in order to diagnose AR and to monitor disease. Inhibitory molecules to IL-17 and IL-33 may be considered as novel treatment strategies.
RESUMEN
The current rampant coronavirus infection in humans, commonly known as COVID-19, a pandemic that may cause mortality in humans, has been declared a global emergency by the World Health Organization (WHO). The morbidity and mortality rates due to the pandemic are increasing rapidly worldwide, with the USA most affected by the disease. The source COVID-19 is not absolutely clear; however, the disease may be transmitted by either by COVID-19-positive individuals or from a contaminated environment. In this review, we focused on how the COVID-19 virus is transmitted in the community. An extensive literature search was conducted using specific keywords and criteria. Based on the published report, it is concluded that COVID-19 is primarily transmitted human-to-human via oral and respiratory aerosols and droplets with the virus-contaminated environment play a lesser role in the propagation of disease. Healthcare providers and the elderly with comorbidities are especially susceptible to the infection.
RESUMEN
BACKGROUND: Diabetes Mellitus is described as a group of metabolic diseases in which the patient has higher blood glucose levels due to many causes. These include a defect in insulin secretion and failure of the body's cells to respond to the hormone. Cytokines and autoantibodies have a critical role in the pathogenesis of diabetes, especially type I. AIM OF THE STUDY: The aim of this study was to measure the serum levels of interleukin-1 beta (IL-1 ß), interleukin-3 (IL-3), interferon-gamma (INF- γ), and glutamic acid decarboxylase autoantibody (GADA) in patients with type I and type II diabetes mellitus. MATERIAL AND METHODS: In this cross-sectional study, serum samples were taken from 250 individuals, including 100 samples from patients with type II diabetes mellitus, 100 samples from healthy controls, and 50 samples from patients with type I diabetes mellitus. Five milliliters of venous blood were taken from each individual and the samples were analyzed for cytokines (IL-1 ß, IL-3, and INF- γ) and GABA using ELISA. RESULTS: In the study, we found that the serum levels of IL-1 ß were significantly higher in the healthy control group compared to the patients with type I and type II diabetes mellitus. The levels of IL-3 and INF- γ were significantly higher in type II diabetes mellitus, while GABA serum levels were higher in type I diabetes mellitus. CONCLUSION: Our data showed that GADA is an important autoantibody, not only in type I but also in type II diabetes mellitus and can probably be used in the future for diagnosis of this disease. There was also a close association of GADA with systemic immunoregulation in type I and II diabetes mellitus. The relation of cytokines (IL-1 ß, IL-3, and INF- γ) and GADA in patients with diabetes will also increase our understanding for the immunology of diabetes mellitus and to propose specific treatment on the basis of our findings. Our data also include correlation between age and the level of cytokines and GADA with different conclusion for each parameter.

A simulation-based training course was designed to support the development of nurses' skills in falls assessment and prevention. National guidance on falls risk assessment and prevention was used to develop the course content. The course enabled participants to practise real-life scenarios in a safe environment, reflect on their performance and receive feedback from their peers. The post-course evaluations showed positive feedback with all the nurses reporting benefit from this style of learning. They all thought their participation would have a significant effect on their clinical practice and aid their ability to care for patients who had fallen. On an organisational level, the trust has seen an 11% reduction in the number of falls since the training was introduced in 2016.

AIM: To determine how the auto-antibodies (Abs) profiles overlap in chronic hepatitis C infection (CHC) and autoimmune hepatitis (AIH) and correlate to liver disease. METHODS: Levels of antinuclear Ab, smooth muscle antibody (SMA) and liver/kidney microsomal-1 (LKM-1) Ab and markers of liver damage were determined in the sera of 50 patients with CHC infection, 20 AIH patients and 20 healthy controls using enzyme linked immunosorbent assay and other immune assays. RESULTS: We found that AIH patients had more severe liver disease as determined by elevation of total IgG, alkaline phosphatase, total serum bilirubin and serum transaminases and significantly higher prevalence of the three non-organ-specific autoantibodies (auto-Abs) than CHC patients. Antinuclear Ab, SMA and LKM-1 Ab were also present in 36% of CHC patients and related to disease severity. CHC cases positive for auto-Abs were directly comparable to AIH in respect of most markers of liver damage and total IgG. These cases had longer disease duration compared with auto-Ab negative cases, but there was no difference in gender, age or viral load. KLM-1+ Ab CHC cases showed best overlap with AIH. CONCLUSION: Auto-Ab levels in CHC may be important markers of disease severity and positive cases have a disease similar to AIH. Auto-Abs might have a pathogenic role as indicated by elevated markers of liver damage. Future studies will unravel any novel associations between these two diseases, whether genetic or other.

In allergic asthma (AA), inflammatory changes in the airway epithelium may contribute to the characteristic pathophysiology and symptoms. The presence of T lymphocytes, eosinophils, mast cells and macrophages, the presence of cytokines, and also structural changes in the airway mucous membrane are characteristic for asthma. Bronchial biopsy specimens were obtained from 33 AA, 25 nonallergic asthma (NAA), and 20 healthy controls (HC). This study used immunohistochemical techniques for identified monoclonal antibodies (CD3, CD4, CD8, CD25, ECP, MBP, tenascin, and laminin) in the bronchi. The highest number of eosinophils and T lymphocyte cells in bronchial biopsies was found in AA, and NAA. The number of T lymphocytes in AA was significantly higher than in NAA and HC. The degree of epithelial damage was higher in the AA group compared to the other groups. The tenascin- and laminin-positive layers in AA were thicker than other groups. In AA, a significant negative correlation was found between epithelial integrity and the count for eosinophils or T lymphocytes. T lymphocytes and eosinophils in AA were found in the area of epithelial and lamina propria damage. This article suggests that T lymphocytes may not only contribute to the chronic airway inflammatory response, airway remodeling, and symptomatology but may also have a central role at the initiation of the allergic immune response. Th-targeted therapy would be of considerable interest in controlling AA. Having more knowledge on the roles of T lymphocytes in the pathogenesis of allergic inflammation highlights the contributions of these cells in regulating and may lead to a new therapeutic target-AA.

Asthma and rhinitis are inflammatory diseases of the respiratory tract. Respiratory inflammation of the adaptive and innate immune system is the focus of this review, and chronic inflammation is not limited to the respiratory tissue. The inflammatory response, which consists of phagocytes, eosinophils, mast cells, and lymphocytes, spreads along the respiratory tract, leading to tissue damage. Mast cells and eosinophils are commonly recognized for their detrimental role in allergic reactions on activation through the high- and low-affinity receptors for IgE FcÉRI. These cells rapidly produce and secrete many of the mediators responsible for the typical symptoms of asthma and rhinitis. However, increasing amount of evidence demonstrate that mast cells and leukocytes have vital roles in host defense against pathogenesis. Histological methods are used to study leukocytes and receptor expression pattern in different respiratory tract compartments. The overall aim of this review was to understand the relationship between upper and lower respiratory tract inflammation and remodeling in patients with allergic and non-allergic asthma and rhinitis. In conclusion, this review discusses the relationship between the upper and lower airway in respiratory disease and focuses on the effect of respiratory processes on laryngeal inflammation, remodeling, function, and symptoms; however, they also have a central role in the initiation of the allergic immune response. Our findings suggest that there are differences that contribute to the development of immunopathological mechanisms of these clinically distinct forms of asthma, rhinitis, and chronic obstructive pulmonary disease.
RESUMEN
Addressing the needs to achieve the highest standards at multidisciplinary team meetings at the Stroke Unit of Broomfield Hospital, an electronic version is applied instead of the traditional paper model. This is to ensure that patients within the unit are receiving appropriate care and their progress is monitored throughout their entire journey. This also enables the stroke team to retrieve old information anywhere in the hospital, electronically, from previous documentations to compare progress of rehabilitation. The electronic model also helps when assessing readmission or those who attend the stroke clinics to clarify new onset changes from residual weakness. The tool kit estimates Barthel Index score for activities of daily living and Rivermead Mobility Index for physical capacity assessment weekly as the team attending the meetings. The goals from all disciplines, physiotherapists, occupational therapists, speech and language therapists, and nurses are clearly documented along with patient cognition, emotion, and perception. This initiative commenced in late April 2013 and the first clinical outcome assessments performed at the beginning of September 2013, enabling the stroke team to assess rehabilitation activities and achievements. Front-line staff expressed satisfaction with the initiative model, which successfully managed to monitor and analyze the rehabilitation activities within the stroke unit.
