Phenotype and Clinicoradiological Differences in Multifocal and Focal Bronchiectasis.

Introduction: Bronchiectasis is a chronic progressive respiratory disease characterized by permanent dilatation of the bronchi. It is a complex condition with numerous different etiologies, co-morbidities, and a heterogeneous presentation. As we know, there is a lack of studies that describe the differences and compare the characteristics between focal and multifocal bronchiectasis. The aim of this study is to identify differences in clinical characteristics presentation, severity or distribution in focal and multifocal bronchiectasis, and prognostic implications. Methods: 126 patients with computed tomography (CT)-verified bronchiectasis were enrolled. Baseline characteristics that included age, sex, smoking history, and respiratory symptoms were recorded, with special attention paid to hemoptysis appearance, body mass index, and comorbidities. The type of bronchiectasis determined by CT scan and the modified Reiff scores indicating radiological severity were recorded. Patients were divided in two groups (I is focal and II is multifocal). Results: There were no statistically significant differences in age, smoking status, comorbidity, and BMI between the two groups. Multifocality was associated with a significantly higher proportion of females (p = 0.014), the rate of hemoptysis (p = 0.023), and the number of hospitalizations, but not of exacerbations and prevalence of immunodeficiency (p = 0.049). Significantly, a high number of subjects with multifocality had bronchiectasis of moderate severity, and post-infective and asthma-associated phenotypes were the dominant in this group. Unexpectedly, the cystic and varicose radiological phenotype (which need more time to develop) were more dominant in the focal group. The cylindrical phenotype was equally observed in the multifocal and focal groups. Conclusions: Our study suggests that multifocality is not related to age, number of exacerbations, or radiological phenotype, but it seems to be associated with the clinical post-infective phenotype, immunodeficiency, frequent hospitalizations, and severity. Thus, the presence of multifocal bronchiectasis may act as a biomarker of severity and poor outcomes in these patients.

Influence of Achalasia on the Spirometry Flow-Volume Curve and Peak Expiratory Flow.

BACKGROUND: Achalasia is an esophageal motor disorder characterized by aperistalsis and the failure of the relaxation of the lower esophageal sphincter. We want to find out whether external compression or recurrent micro-aspiration of undigested food has a functional effect on the airway. METHODS: The aim of this research was to analyze the influence of achalasia on the peak expiratory flow and flow-volume curve. All of the 110 patients performed spirometry. RESULTS: The mean diameter of the esophagus was 5.4 ± 2.1 cm, and nine of the patients had mega-esophagus. Seven patients had a plateau in the inspiratory part of the flow-volume curve, which coincides with the patients who had mega-esophagus. The rest of the patients had a plateau in the expiration part of the curve. The existence of a plateau in the diameter of the esophagus of more than 5 cm was significant (p 0.003). Statistical significance between the existence of a plateau and a lowered PEF (PEF < 80) has been proven (p 0.001). Also, a statistical significance between the subtype and diameter of more than 4 cm has been proved. There was no significant improvement in the PEF values after operation. In total, 20.9% of patients had a spirometry abnormality finding. The frequency of the improvement in the spirometry values after surgery did not differ significantly by achalasia subtype. The improvement in FEV1 was statistically significant compared to the FVC values. CONCLUSIONS: Awareness of the influence of achalasia on the pulmonary parameters is important because low values of PEF with a plateau on the spirometry loop can lead to misdiagnosis. The recognition of various patterns of the spirometry loop may help in identifying airway obstruction caused by another non-pulmonary disease such as achalasia.

Correlation between Radiological Characteristics, PET-CT and Histological Subtypes of Primary Lung Adenocarcinoma-A 102 Case Series Analysis.

Background and Objectives: Lung cancer is the second most common form of cancer in the world for both men and women as well as the most common cause of cancer-related deaths worldwide. The aim of this study is to summarize the radiological characteristics between primary lung adenocarcinoma subtypes and to correlate them with FDG uptake on PET-CT. Materials and Methods: This retrospective study included 102 patients with pathohistologically confirmed lung adenocarcinoma. A PET-CT examination was performed on some of the patients and the values of SUVmax were also correlated with the histological and morphological characteristics of the masses in the lungs. Results: The results of this analysis showed that the mean size of AIS-MIA (adenocarcinoma in situ and minimally invasive adenocarcinoma) cancer was significantly lower than for all other cancer types, while the mean size of the acinar cancer was smaller than in the solid type of cancer. Metastases were significantly more frequent in solid adenocarcinoma than in acinar, lepidic, and AIS-MIA cancer subtypes. The maximum standardized FDG uptake was significantly lower in AIS-MIA than in all other cancer types and in the acinar predominant subtype compared to solid cancer. Papillary predominant adenocarcinoma had higher odds of developing contralateral lymph node involvement compared to other types. Solid adenocarcinoma was associated with higher odds of having metastases and with higher SUVmax. AIS-MIA was associated with lower odds of one unit increase in tumor size and ipsilateral lymph node involvement. Conclusions: The correlation between histopathological and radiological findings is crucial for accurate diagnosis and staging. By integrating both sets of data, clinicians can enhance diagnostic accuracy and determine the optimal treatment plan.

ADA as main biochemical marker in patients with tuberculous effusion.

Tuberculous pleuritis (TP) is one of the most common extra-pulmonary tuberculosis form. Because of tuberculous pleurisy is hard to diagnose due to slow course of disease and lack of specificity in symptoms and diagnostic methods. In that reason, we need multidisciplinary approach and efficient biomarkers. Acid-fast bacilli (AFB) staining, cultures and pathophysiological biopsy finding from the majority of patients are positive only in less than 10%. Löwenstein culture results need time about 6-8 weeks what delays diagnosis. Adenosine deaminase (ADA) is biomarker with high sensitivity and specificity (more than 90%) and considered as gold standard of biomarkers in the diagnosis of TP. It is very hard to distinguish malignant from TP with lymphocyte predomination, but in patient with malignant pleural effusion the level of ADA is decreased, opposite from TP. ADA in pleural punctate is a fast, simple, efficient and economical way for clarification the etiology of the pleural effusion as tuberculous pleurisy. Also, many studies have proved the role of ADA in the response to treatment for tuberculosis at follow up period.

Integration of migrant and refugee data in health information systems in Europe: advancing evidence, policy and practice.

Coverage of migrant and refugee data is incomplete and of insufficient quality in European health information systems. This is not because we lack the knowledge or technology. Rather, it is due to various political factors at local, national and European levels, which hinder the implementation of existing knowledge and guidelines. This reflects the low political priority given to the topic, and also complex governance challenges associated with migration and displacement. We review recent evidence, guidelines, and policies to propose four approaches that will advance science, policy, and practice. First, we call for strategies that ensure that data is collected, analyzed and disseminated systematically. Second, we propose methods to safeguard privacy while combining data from multiple sources. Third, we set out how to enable survey methods that take account of the groups' diversity. Fourth, we emphasize the need to engage migrants and refugees in decisions about their own health data. Based on these approaches, we propose a change management approach that narrows the gap between knowledge and action to create healthcare policies and practices that are truly inclusive of migrants and refugees. We thereby offer an agenda that will better serve public health needs, including those of migrants and refugees and advance equity in European health systems. Funding: No specific funding received.

RETRO-POPE: A Retrospective, Multicenter, Real-World Study of All-Cause Mortality in COPD.

Purpose: The Phenotypes of COPD in Central and Eastern Europe (POPE) study assessed the prevalence and clinical characteristics of four clinical COPD phenotypes, but not mortality. This retrospective analysis of the POPE study (RETRO-POPE) investigated the relationship between all-cause mortality and patient characteristics using two grouping methods: clinical phenotyping (as in POPE) and Burgel clustering, to better identify high-risk patients. Patients and Methods: The two largest POPE study patient cohorts (Czech Republic and Serbia) were categorized into one of four clinical phenotypes (acute exacerbators [with/without chronic bronchitis], non-exacerbators, asthma-COPD overlap), and one of five Burgel clusters based on comorbidities, lung function, age, body mass index (BMI) and dyspnea (very severe comorbid, very severe respiratory, moderate-to-severe respiratory, moderate-to-severe comorbid/obese, and mild respiratory). Patients were followed-up for approximately 7 years for survival status. Results: Overall, 801 of 1,003 screened patients had sufficient data for analysis. Of these, 440 patients (54.9%) were alive and 361 (45.1%) had died at the end of follow-up. Analysis of survival by clinical phenotype showed no significant differences between the phenotypes (P=0.211). However, Burgel clustering demonstrated significant differences in survival between clusters (P<0.001), with patients in the "very severe comorbid" and "very severe respiratory" clusters most likely to die. Overall survival was not significantly different between Serbia and the Czech Republic after adjustment for age, BMI, comorbidities and forced expiratory volume in 1 second (hazard ratio [HR] 0.80, 95% confidence interval [CI] 0.65-0.99; P=0.036 [unadjusted]; HR 0.88, 95% CI 0.7-1.1; P=0.257 [adjusted]). The most common causes of death were respiratory-related (36.8%), followed by cardiovascular (25.2%) then neoplasm (15.2%). Conclusion: Patient clusters based on comorbidities, lung function, age, BMI and dyspnea were more likely to show differences in COPD mortality risk than phenotypes defined by exacerbation history and presence/absence of chronic bronchitis and/or asthmatic features.

The influence of gender differences on the illness perception and women's point of view on COPD.

OBJECTIVES: Chronic obstructive pulmonary disease (COPD) is an irreversible disease and has influence on patients' quality of life. The aim is to investigate the influence of gender on the illness perception in COPD patients. MATERIALS AND METHODS: This prospective study enrolled 151 COPD patients. For the evaluation of illness perception, we used Brief Illness Perception Questionnaire (BIPQ). RESULTS: Average FEV1 values were significantly different (p = 0.007) in favor of woman compared to men. There was a higher proportion of GOLD stage 3 and less stage 4 in women. We found a significant difference in total BIPQ scores between female and male patients (p = 0.008). Women gave a significantly higher score on question 6 and 8 (p = 0.003). We found a significant difference in total BIPQ scores between female and male patients. Women perceive COPD as a significantly more threatening disease and accept chronic course and long-term treatment. CONCLUSION: COPD is no longer a disease that predominantly affects men. BIPQ is a convenient tool for fast assessment of illness perception for COPD. Patients' perceptions of COPD is in correlation with gender and GOLD stadium. The results of this study have potential benefits in terms of health promotion and improvement of the quality of life and outcome (Fig. 4, Ref. 21).

Healthcare professionals' views on the accessibility and acceptability of perinatal mental health services for South Asian and Black women: a qualitative study.

BACKGROUND: Perinatal mental illness affects one third of new and expectant mothers. Individuals from ethnic minority groups experience higher rates of mental health problems and higher suicide rates. Despite this, women from ethnic minorities-Black and South Asian women in particular-are less likely to receive support from mental health services in the perinatal period. Healthcare professionals (HCPs) who have contact with women during this period have a unique perspective, and their views may provide insights to understand and remedy this health inequality. This study aimed to identify healthcare professionals' views on the current accessibility and acceptability of perinatal mental health services, and ways of improving services by addressing the barriers for these women. METHODS: Semi-structured interviews were conducted with twenty-four healthcare professionals who work with patients in the perinatal period. Purposive sampling was used to select HCPs from a range of different professions (including mental health staff, midwifery, primary care, social care). The data were analysed using Framework Analysis. RESULTS: Three main themes were identified from the data: (1) lack of awareness and understanding of perinatal mental illness and service structure in both healthcare professionals and patients; (2) patients' relationships with family, friends and healthcare professionals can both hinder and facilitate access to services; (3) healthcare professionals encourage raising awareness, flexibility, developing shared understandings and questioning assumptions to improve the accessibility and acceptability of services. CONCLUSION: Key insights into explaining and remedying the health inequalities observed between ethnic groups were proposed by healthcare professionals. Recommendations included sharing information; taking steps to ensure each woman was considered as an individual in her relationship with her culture, ethnicity and childrearing practices; and healthcare professionals addressing their possible unconscious biases through engaging in personal reflexive practices. Reasons these are currently not being implemented deserve further research, and the potential of novel roles such as peer support workers in bridging the space between ideals and practice needs further investigation.

Achalasia Subtype Differences Based on Respiratory Symptoms and Radiographic Findings.

Three subtypes of achalasia have been defined using esophageal manometry. Several studies have reported that symptoms are experienced differently among men and women, regardless of subtype. All subtypes could have some impact on the appearance of respiratory symptoms and lung complications due to compression of the trachea or aspiration of undigested food. The aim of this research was to analyze the differences in respiratory symptoms and radiographic presentation of lung pathology depending on the diameter and achalasia types. One or more respiratory symptoms were reported in 48% of 114 patients, and all of them had two or more gastrointestinal symptoms. The symptom score (SS) is statistically significant for the prediction of subtype 1 (area under the curve = 0.318; p < 0.001, cut-off score of 6.5 had 95.2% sensitivity) and subtype 2 (area under the curve = 0.626; p = 0.020, cut-off score of 7.5 had 93.1% sensitivity). The most common type was subtype 2 (50.8%), and although only 14 patients had subtype 3, they had the largest esophageal diameter (mean 5.8 cm). The difference in esophageal diameter was significant between subtype 1 and 3 (p = 0.011), subtype 2 and subtype 3 (p = 0.011). Nine patients (6%) had mega-esophagus (four patients in type 1, three in type 2 and two in type 3). More than half of all patients (51.7%) had at least one parenchymal lung change on CT scan. Recurrent micro-aspirations led to changes in the structure of the airways and lung parenchyma such as ground glass (GGO) and nodular changes (12%) and fibrosis (14.5%), and they had higher esophageal diameters (p < 0.001). Patients with chronic lung CT changes had significantly higher esophageal diameter than with acute changes (p < 0.001). Awareness of the association of achalasia and lung disorders is important in early diagnosis and treatment. More than half (57.5%) of patients with achalasia had some clinical and/or structural pulmonary abnormalities. All three subtypes had similar respiratory symptoms, meaning they cannot be used to predict the subtype of achalasia; on the contrary, SS can predict the first two subtypes. A higher diameter of the esophagus is associated with chronic structural lung changes. Although unexpected, the pathological radiological findings and diameter were significantly different in subtype 3 patients, but those parameters cannot lead us to a specified subtype.

Isotherm, Thermodynamic and Kinetic Studies of Elemental Sulfur Removal from Mineral Insulating Oils Using Highly Selective Adsorbent.

Elemental sulfur (S8) is a corrosive sulfur compound which was found to be extremely reactive to silver, causing intensive silver sulfide (Ag2S) deposition on on-load tap changer (OLTC) contacts in power transformers. A highly selective adsorbent (HSA), called Tesla'Ssorb, for the removal of S8 from mineral insulating oils was prepared from raw material (RM) using the novel procedure. In this study, the adsorption properties of HSA for the removal of S8 from the oil were determined. RM and HSA were characterized using various techniques, such as field-emission scanning electron microscopy (FESEM), energy-dispersive X-ray (EDX), and X-ray diffraction (XRD). The performance of HSA was determined by adsorption equilibrium, thermodynamic, and kinetic study through batch experiments, at various temperatures and initial concentrations of S8. The obtained results were analyzed by Langmuir and Freundlich adsorption isotherms and it was found that equilibrium data were fitted better with the Langmuir isotherm model. The maximum adsorption capacity was 4.84 mg of S8/g of HSA at 353 K. Thermodynamic parameters, such as enthalpy (ΔH°), Gibbs free energy (ΔG°), and entropy (ΔS°), were calculated and it was found that the sorption process was spontaneous (ΔG° < 0) and endothermic in nature (ΔH° > 0). It was found that the adsorption of S8 follows pseudo-second-order kinetic model, and the activation energy indicated the activated chemisorption process.

Exploring Black and South Asian women's experiences of help-seeking and engagement in perinatal mental health services in the UK.

Background and aims: In the United Kingdom (UK), Black and South Asian women are less likely than White British women to access support from perinatal mental health services, despite experiencing similar, or higher, levels of distress. This inequality needs to be understood and remedied. The aim of this study was to answer two questions: how do Black and South Asian women experience (1) access to perinatal mental health services and (2) care received from perinatal mental health services? Method: Semi-structured interviews were conducted with Black and South Asian women (n = 37), including four women who were interviewed with an interpreter. Interviews were recorded and transcribed line-by-line. Data were analyzed using framework analysis, by an ethnically diverse multidisciplinary team of clinicians, researchers and people with lived experience of perinatal mental illness. Results: Participants described a complex interplay of factors that impacted on seeking, and receiving help, and benefiting from services. Four themes emerged that captured the highly varied experiences of individuals: (1) Self-identity, social expectations and different attributions of distress deter help-seeking; (2) Hidden and disorganized services impede getting support; (3) The role of curiosity, kindness and flexibility in making women feel heard, accepted and supported by clinicians; (4) A shared cultural background may support or hinder trust and rapport. Conclusion: Women described a wide range of experiences and a complex interplay of factors impacting access to, and experience of, services. Women described services as giving them strength and also leaving them disappointed and confused about where to get help. The main barriers to access were attributions related to mental distress, stigma, mistrust and lack of visibility of services, and organizational gaps in the referral process. These findings describe that many women feel heard, and supported by services, reporting that services provide a high quality of care that was inclusive of diverse experiences and understandings of mental health problems. Transparency around what PMHS are, and what support is available would improve the accessibility of PMHS.

The usefulness of MMP-9, TIMP-1 and MMP-9/TIMP-1 ratio for diagnosis and assessment of COPD severity.

BACKGROUND: Inflammation, oxidative stress and an imbalance between proteases and protease inhibitors are recognized pathophysiological features of chronic obstructive pulmonary disease (COPD). The aim of this study was to evaluate serum levels of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in patients with COPD and to assess their relationship with lung function, symptom severity scores and recent acute exacerbations. METHODS: In this observational cohort study, serum levels of MMP-9 and TIMP-1 and the MMP-9/TIMP-1 ratio in the peripheral blood of COPD patients with stable disease and healthy controls were determined, and their association with lung function (postbronchodilator spirometry, body plethysmography, single breath diffusion capacity for carbon monoxide), symptom severity scores (mMRC and CAT) and exacerbation history were assessed. RESULTS: COPD patients (n = 98) had significantly higher levels of serum MMP-9 and TIMP-1 and a higher MMP-9/TIMP-1 ratio than healthy controls (n = 47) (p ≤ 0.001). The areas under the receiver operating characteristic curve for MMP-9, TIMP-1 and the MMP-9/TIMP-1 ratio for COPD diagnosis were 0.974, 0.961 and 0.910, respectively (all p < 0.05). MMP-9 and the MMP-9/TIMP-1 ratio were both negatively correlated with FVC, FEV1, FEV1/FVC, VC, and IC (all p < 0.05). For MMP-9, a positive correlation was found with RV/TLC% (p = 0.005), and a positive correlation was found for the MMP-9/TIMP-1 ratio with RV% and RV/TLC% (p = 0.013 and 0.002, respectively). Patients with COPD GOLD 3 and 4 presented greater MMP-9 levels and a greater MMP-9/TIMP-1 ratio compared to GOLD 1 and 2 patients (p ≤ 0.001). No correlation between diffusion capacity for carbon monoxide and number of acute exacerbations in the previous year was found. CONCLUSIONS: COPD patients have elevated serum levels of MMP-9 and TIMP-1 and MMP-9/TIMP-1 ratio. COPD patients have an imbalance between MMP-9 and TIMP-1 in favor of a pro-proteolytic environment, which overall indicates the importance of the MMP-9/TIMP-1 ratio as a potential biomarker for COPD diagnosis and severity.

Performance and Agreement When Annotating Chest X-ray Text Reports-A Preliminary Step in the Development of a Deep Learning-Based Prioritization and Detection System.

A chest X-ray report is a communicative tool and can be used as data for developing artificial intelligence-based decision support systems. For both, consistent understanding and labeling is important. Our aim was to investigate how readers would comprehend and annotate 200 chest X-ray reports. Reports written between 1 January 2015 and 11 March 2022 were selected based on search words. Annotators included three board-certified radiologists, two trained radiologists (physicians), two radiographers (radiological technicians), a non-radiological physician, and a medical student. Consensus labels by two or more of the experienced radiologists were considered "gold standard". Matthew's correlation coefficient (MCC) was calculated to assess annotation performance, and descriptive statistics were used to assess agreement between individual annotators and labels. The intermediate radiologist had the best correlation to "gold standard" (MCC 0.77). This was followed by the novice radiologist and medical student (MCC 0.71 for both), the novice radiographer (MCC 0.65), non-radiological physician (MCC 0.64), and experienced radiographer (MCC 0.57). Our findings showed that for developing an artificial intelligence-based support system, if trained radiologists are not available, annotations from non-radiological annotators with basic and general knowledge may be more aligned with radiologists compared to annotations from sub-specialized medical staff, if their sub-specialization is outside of diagnostic radiology.

Iron deficiency in nonanaemic COPD patients-Could Low haemoglobin density and Microcytic anaemia factor be usefull?

INTRODUCTION: Erythrocyte indices LHD and Maf are complementary parameters to complete blood count and have been shown as reliable iron deficiency markers in different clinical settings. The aim of the study was to assess diagnostic performances of LHD and Maf in detecting iron deficiency in nonanaemic stable COPD patients. METHODS: A total of 93 nonanaemic stable COPD patients were classified as either iron deficient (ID, N = 15) or non-iron deficient (non-ID, N = 78). Iron deficiency was defined as a ferritin level < 100 µg/L with a transferrin saturation (TSAT) <20%. A complete blood count, including LHD and Maf as well as other relevant inflammation and iron status parameters were obtained for all participants. RESULTS: Both LHD and Maf have shown significant differences between the ID and non-ID group with p = .003 and p = .007 respectively. The AUC for LHD was .744 (95% CI: .626-.863, p = .003) with the best cut-off of 5.85 and sensitivity of 80% (95% CI: 76.0-84.0) and specificity of 61.5% (95% CI: 58.4-64.6). The AUC for Maf was .707 with optimal cut-off value 12.65 and sensitivity of 83.3% (95% CI: 79.1-87.5) and specificity of 60.0% (95% CI: 57.0-63.0). Furthermore, LHD performance was not affected by vitamin B12 status. CONCLUSION: LHD and Maf are useful for iron deficiency diagnosis in stable COPD patients. LHD was shown to be resistant to vitamin B12 deficiency, which is of substantial importance in specific patient subpopulations. Both parameters are not technology-dependant and do not require additional sample and/or reagent volume, which makes them cost-effective and convenient for everyday use.

Pneumonia caused by Sphingomonas paucimobilis infection after a dental intervention.

INTRODUCTION: Sphingomonas paucimobilis can be found in air, water systems, dialysis fluid, nebulizers and laboratory instruments in hospitals. Despite its low pathogenicity, it can cause severe infections. CASE REPORT: A 54-year-old man presented with fever, cough and pain in the right hemithorax. The laboratory results showed elevated inflammatory parameters. Chest radiography showed right upper lobe pneumonia. Empiric antibiotic therapy (cephalosporin) was prescribed. On control examination chest radiography showed incomplete regression. Chest computer tomography (CT) finding was bronchopneumonia in the right upper lobe. Bacteriological examination of fiberaspirate revealed Sphingomonas paucimobils. Trimethoprim-sulfamethoxazole was prescribed based on the antibiogram. After two weeks the control laboratory analysis was normal. The patient was fully recovered. CONCLUSIONS: Our patient had no comorbidities or malignancies, and no hospitalization in the recent past. He had a dental intervention 5 days prior to the onset of symptoms. We propose that it was an infection after the dental intervention.

Lung Abnormalities in Severe Acute Respiratory Syndrome Coronavirus 2 Infection: An Analysis of Paired Computed Tomography Scans Before and After Infection.

Background: Studies on the pulmonary consequences of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are impeded by limited access to pre-SARS-CoV-2 examinations. Methods: We invited Copenhagen General Population Study participants with a confirmed SARS-CoV-2 polymerase chain reaction (PCR) test during the first and second coronavirus disease 2019 waves in Denmark for a repeat chest computed tomography (CT) scan. Paired CT scans were independently assessed for interstitial and noninterstitial abnormalities by 2 trained radiologists. A semiquantitative CT score (ranging from 0 to 20) was used to quantify the extent of interstitial abnormalities. Results: Of 111 SARS-CoV-2-infected individuals, 102 (91.2%) experienced symptoms and 12 (11.2%) were hospitalized. Follow-up examination was performed at median of 5.4 (interquartile range, 4.1-7.8) months after a positive SARS-CoV-2 PCR test. Of 67 individuals with paired CT scans, ground glass opacities and reticulation were present in 31 (46.3%) individuals post-SARS-CoV-2 compared to 23 (34.1%) pre-SARS-CoV-2 (mean CT score, 3.0 vs 1.3; P = .011). Results were similar for nonhospitalized individuals. We did not detect development of bronchiectasis, emphysema, or nodules. Conclusions: SARS-CoV-2 infection in predominantly nonhospitalized individuals with mild disease was associated with a small increase in only interstitial lung abnormalities.

Anxiety and Comorbidities Differences in Adults with Chronic Pulmonary Diseases: Serbian Single Center Experience.

Background and objectives: The purpose of this study is to investigate the differences in the degree of the anxiety and comorbidity levels in patients with different chronic pulmonary diseases such as chronic obstructive bronchitis (COPD) without emphysema phenotype, pulmonary emphysema, bronchial asthma and lung cancer. Materials and Methods: The prospective clinical study included 272 patients that were diagnosed and treated of pulmonary pathology. COPD (without emphysema phenotype) (Group-1), pulmonary emphysema (Group-2), bronchial asthma (Group-3) and lung cancer (Group-4) were assessed. For the evaluation of the anxiety degree, we used Hamilton Anxiety Rating Scale (HAM-A). Results: The degree of cardiovascular symptoms was significantly higher in Group-1 versus Group-2 (p < 0.001), Group-3 (p = 0.001) and Group-4 (p = 0.013), and significantly higher in Group-4 versus Group-2 (p = 0.046). The degree of respiratory symptoms was significantly higher in Group-1 versus Group-2 (p < 0.001), Group-3 (p < 0.001) and Group-4 (p = 0.002), and significantly higher in Group-4 versus Group-2 (p = 0.013) and versus Group-3 (p = 0.023). For gastrointestinal symptoms, the degree of one was significantly higher in Group-1 versus Group-2 (p < 0.001), Group-3 (p < 0.001) and Group-4 (p = 0.017). Somatic subscale values were significantly higher in Group-1 versus Group-2 (p < 0.001), Group-3 (p < 0.001) and Group-4 (p = 0.015), and significantly higher in Group-4 versus Group-2 (p = 0.024). Total HAM-A score was significantly higher in Group-1 versus Group-2 (p = 0.002) and Group-3 (p = 0.007). Conclusions: Patients with COPD (without emphysema phenotype) followed by the lung cancer are at elevated risk of being more mentally challenged in terms of increased anxiety. Furthermore, patients with exacerbation of evaluated pulmonary pathologies have various levels of comorbidities degrees.

Neoveil versus TachoSil in the treatment of pulmonary air leak following open lung surgery: a prospective randomized trial.

OBJECTIVES: Prolonged air leak (PAL) is often associated with pain and immobilization and is a major limiting factor for discharge from the hospital. The efficacy of 2 surgical patches was investigated in the treatment of air leak following open surgery. METHODS: Forty-five patients were randomized in a 1:1 ratio either to treatment with Neoveil (polyglycolic acid) (n = 22) or TachoSil (collagen sponge) (n = 23). Air leak was monitored at 2, 4, 8, 12 and 24 h after surgery and then daily at 8 am and 6 pm, using a digital recording system. The primary outcome was the time to air leak closure. Secondary outcomes were incidence, air leak intensity, incidence of PAL and incidence of pneumonia. RESULTS: Air leak 2 h after surgery was observed in 11/22 (50%) vs 14/23 (61%) patients treated with polyglycolic acid, respectively, with collagen sponge. On average, air loss within the first 24 h after surgery was lower and declined faster in patients treated with polyglycolic acid. Time to pulmonary air leak closure was somewhat shorter with polyglycolic acid (median [interquartile range] 10 [2, 52] h) compared to collagen sponge (19 [2, 141] h). However, the difference was not statistically significant (P = 0.35, Wilcoxon rank-sum test). PAL occurred in 3/22 (14%) vs 6/23 (26%) patients, and pneumonia occurred in 2/22 (9%) vs 3/23 (13%) patients treated with polyglycolic acid, respectively, collagen sponge. CONCLUSIONS: Both systems are effective in the treatment of air leak. Our results suggest a possible superiority of Neoveil over TachoSil in post-surgery air leak control.

Differences in access and utilisation of mental health services in the perinatal period for women from ethnic minorities-a population-based study.

BACKGROUND: Barriers to accessing mental health care during pregnancy and the first postnatal year (perinatal period) seem to be greater for ethnic minority women; however, there is no reliable large-scale data about their actual use of mental health services during this period. Our study aims to explore access rates to secondary mental health services, including involuntary admissions to psychiatric inpatient care and patterns of engagement for ethnic minority women aged 18+ who gave birth in 2017 in England, UK. METHODS: Two datasets from the National Commissioning Data Repository, the Acute Inpatient Dataset and Mental Health Services Dataset, were linked. Datasets covering the full perinatal period for each woman were included. Rates were standardised by age and deprivation. RESULTS: Out of 615,092 women who gave birth in England in 2017, 22,073 (3.5%) started a contact with mental health services during the perinatal period. In total, 713 (3.2%) were admitted to inpatient care, and 282 (39.5%) involuntarily. Ethnicity data was available for 98% of the sample. Black African, Asian and White Other women had significantly lower access to community mental health services and higher percentages of involuntary admissions than White British women. Black African, Asian and White Other women had a higher number of attended community contacts and fewer non-attendances/cancellations of appointments than White British women. CONCLUSION: Access to mental health services during the perinatal period varies significantly between women from different ethnic groups. Access to community mental health services should be facilitated for Black African, Asian and White Other women during the perinatal period, which may reduce rates of involuntary hospital admissions for these groups. The pattern of engagement with community services for women from these ethnicities indicates that access appears to be a problem rather than utilisation.

Understanding the lived experiences of severe postnatal psychiatric illnesses in English speaking South Asian women, living in the UK: a qualitative study protocol.

INTRODUCTION: The South Asian population is the UK's largest and fastest growing minority ethnic group. There is evidence to suggest the lay understanding of postnatal psychiatric illnesses of this group may fall outside the purview of Western biomedical perspectives. Alternative explanations include psychosocial, cultural and spiritual factors. Approaching psychiatric illnesses through a social perspective includes gaining insight to the patient's subjective experiences and understandings via qualitative inquiry. The objectives of this qualitative study are to explore South Asian women's narrative of living with a severe postnatal psychiatric illness and experiences of Perinatal Mental Health Services, care and support. METHODS AND ANALYSIS: Data collection is ongoing and will continue until 31 December 2018. Participants will be identified and recruited from Perinatal Mental Health Services in Birmingham and London. Eligible participants will be English speaking South Asian females aged 18 years or above with the capacity to give written informed consent. Participants are clinically diagnosed with a severe postnatal psychiatric illness. This qualitative study uses individual in-depth face-to-face interviews that aim to last 1 hour. Interviews will be audio recorded with participants' permission. Interview audio recordings will be transcribed verbatim and analysed using interpretative phenomenological analysis (IPA). The primary goal of IPA is for the researcher to closely study and interpret how individuals make sense of their life experiences in a particular context by drawing on the fundamental principles of phenomenology, hermeneutics and idiography. ETHICS AND DISSEMINATION: The University of Birmingham, the South Birmingham Research Ethics Committee and the Health Research Authority have approved this study (approvals date: 18-12-2017 ref: 17/WM/0350). Local capability and capacity have been confirmed from Trust Research and Development departments. The researchers plan to publish the results from this study in journals and present findings at academic conferences.
