Aims: to measure the clinical impact of contrast-enhanced ultrasound (CEUS) in the diagnosis of -community-acquired pneumonia (CAP), compared to clinical, radiological and ultrasound diagnosis.

Methods: 84 patients (47/37 males/females, mean age:78,57±11,7 Y) with clinical suspicion of pneumonia and with ultrasound findings of peripheral lung lesions, were investigated with CEUS for a better characterization. Final diagnosis of 65 cap was obtained with complete disappearance of symptoms and pulmonary nodule(s); 19 neoplasms: 16 patients performed histologically with bronchoscopy; 3 refused (non-invasive diagnosis with basal CT-scan and positron emission tomography (PET) with fluorodeoxyglucose (FDG)). Sensitivity, specificity, overall diagnostic accuracy (ODA) (and corresponding AUROC) of clinical-data (CD), chest X-ray(CXR), Lung-ultrasound(LUS), CEUS were calculated with SPSS 26.0 software.

Results: Final diagnosis: 65 CAP, and 19 chest cancers. 9/65 (13%) patients died, of these 7/9 with older age and heart disease as comorbidity. CD: True-Positive (TP):23, True-negative (TN): 17; False-Positive (FP):2; False-negative (FN):42 (sens:35,4% spec:89,5% ODA10%: PPV:92%, NPV:28,8%) (AUROC±SEauc:0,46±0,076); CXR: TP: 36, TN:14; FP:5, FN:29; (sens: 55,4%; spec: 73,7%; ODA: 32%; PPV:87,5%, NPV:32,66%) (AUROC±SEauc:0,645±0,068). US: TP:59; TN: 14; FP:5, FN:6 (sens: 90,8%, spec: 73,7%, ODA: 84,9%, PPV:92,2%, NPV:70%) (AUROC±SEauc:0,9417±0,024); CEUS: TP: 63; TN: 19; FP:0; FN:2 (sens: 96,9%; spec: 100% ODA: 97,5%; PPV: 100%, NPV:90,5%) (AUROC±SEauc:0,98±0,01).

Conclusions: Clinical-data and chest X-RAYS are insufficient to obtain a correct diagnosis of CAP in elderly population; US demonstrated a good accuracy to establish CAP, but with a relatively low specificity; in these cases, CEUS is able to give a correct characterization, allowing you to save the need for a chest contrast-enhanced-CT (CECT).

Background: The management of chronic obstructive pulmonary disease (COPD) lacks standardization due to the diverse clinical presentation, comorbidities, and limited acceptance of recommended approaches by physicians. To address this, a multicenter study was conducted among Italian respiratory physicians to assess consensus on COPD management and pharmacological treatment.

Methods: The study employed the Delphi process using the Estimate-Talk-Estimate method, involving a scientific board and expert panel. During a 6-month period, the scientific board conducted the first Delphi round and identified 11 broad areas of COPD management to be evaluated while the second Delphi round translated all 11 items into statements. The statements were subsequently presented to the expert panel for independent rating on a nine-point scale. Consensus was considered achieved if the median score was 7 or higher. Consistently high levels of consensus were observed in the first rating, allowing the scientific board to finalize the statements without requiring further rounds.

Results: Topics generating substantial discussion included the pre-COPD phase, patient-reported outcomes, direct escalation from a single bronchodilator to triple therapy, and the role of adverse events, particularly pneumonia, in guiding triple therapy prescriptions. Notably, these topics exhibited higher standard deviations, indicating greater variation in expert opinions.

Conclusions: The study emphasized the significance that Italian pulmonologists attribute to managing mortality, tailoring treatments, and addressing cardiovascular comorbidities in COPD patients. While unanimous consensus was not achieved for all statements, the results provide valuable insights to inform clinical decision-making among physicians and contribute to a better understanding of COPD management practices in Italy.

Background: Asthma is the most common chronic non-communicable disease in children and one of the most common in adults, and the majority of asthma-related deaths are attributed to middle- and low-income countries. Physicians' knowledge and practice have been recognized as fundamental elements in the approach to the asthmatic patient with an impact on the treatment and control of the disease. This study aimed to assess the knowledge and practice of Angolan physicians in the management of asthma, as well as to identify the main gaps.

Methods: It was a cross-sectional study carried out in Angola. The data were collected through an online questionnaire to assess the knowledge about asthma among the physicians and the Physicians Practice Assessment Questionnaire. Categorical variables were described with frequencies and percentages. All associations between good practice and possible predictors were established with logistic regression analysis. P<0.05 was considered statistically significant.

Results: A total of 204 physicians throughout Angola participated; the majority of whom were female, aged -between 31 and 40, and from the Luanda province. The average percentage of correct answers for all domains was 65.8% (±SD11.1%). The lowest percentages were in the answers about the diagnosis, drugs, and the signs of an asthma attack. Out of the 204 participants, 81.9% of physicians confirmed seeing patients with asthma. The average percentage of them who reported practicing asthma management based on recommended guidelines was 59.8% (±SD27.8%). More than half of the physicians did not achieve that percentage. The lowest percentages of correct answers concerned assessment of the inhaler technique, provision of a written referral for asthma education, and use of the GINA guidelines to assess the patient's asthma control. Concerning the predictors of best practices, our results showed that being a physician of older age and with more work experience, as well as having the category of specialist were significant predictors of adherence to recommended practices for asthma management.

Conclusions: The physicians' level of knowledge about asthma was moderate, but there are important practical gaps in asthma management regarding standard guidelines.

                                                                 Abstract Background: Few studies have addressed the effects of biological therapies on laboratory outcomes and changes in FEV1 in patients with severe asthma (SA) and chronic rhinosinusitis (CRS). We aimed to study the effect of three biological therapies on laboratory outcomes and FEV1 in Saudi Arabian patients with SA and CRS.

Methods: From March to September 2022, a retrospective observational cohort study was undertaken at the severe asthma clinics of the Armed Forces Hospital-Southern Region (AFHSR) and King Khalid University Hospital, Abha, Saudi Arabia, to delineate the effects of 3 biological therapies (benralizumab, dupilumab, and omalizumab) in adults with SA and concomitant CRS in terms of FEV1 and laboratory parameters (serum IgE and eosinophilic counts).

Results: Eighty patients were enrolled, with a mean age of 46.68. There were 45 (56%) females and 35 (44%) males. There were significant improvements in FEV1 and laboratory parameters (serum IgE and eosinophilic counts) after 6 &12 months of biological therapies compared to pre-biological therapies (p<0.001, each). The response was different among different biological therapies. The improvements in FEV1, serum IgE, and eosinophilic counts were manifest with benralizumab and dupilumab but not with omalizumab.

Conclusions: Results from the first study from two large Saudi Arabian tertiary centers for patients with severe asthma and chronic rhinosinusitis agree with and support those of worldwide real-life ones. One-year follow-up of patients with SA and CRS showed the effectiveness of benralizumab and dupilumab, but not omalizumab, regarding FEV1, serum IgE, and eosinophilic counts. Further prospective multicenter studies are warranted.

Topical nasal therapy is widely used in clinical practice by different specialists. However, it is multifaceted and still controversial. Namely, there is no consensus about the many aspects, and there needs to be specific guidelines. Four independent experts involved 14 Italian scientific societies (concerning ENT, allergy, and pediatrics areas) to participate in generating an Intersocietal Delphi Consensus on this matter. Three iterative rounds collected experts (4 in the first round, 20 in the second round, and 45 in the third round) designed by the scientific societies based on their clinical expertise and documented scientific value. Thirty-four statements were discussed and voted on. At the second round, all statements accomplished a very high consensus grade (>95%). At the third round, many statements reached a high or very high grade of consensus (>70%). However, some statements did not obtain sufficient agreement. Consequently, there is a need to implement knowledge about this issue through educational initiatives and new studies conducted with a robust methodology. In conclusion, topical nasal therapy deserves adequate knowledge as it is widespread and fruitful in managing upper respiratory diseases.

Background: Pulmonary sequestration is a congenital malformation in which nonfunctional lung tissue develops without connection to the bronchial system. The main complication is the occurrence of recurrent pneumonia.

Case presentation: We describe the case of a patient who was incidentally diagnosed with PS as part of the diagnostic algorithm for community-acquired pneumonia. Due to the relatively late diagnosis, the recurrent bronchopulmonary was conducive to the development of COPD and pulmonary emphysema. For prognostic reasons, surgical resection was performed by posterolateral thoracotomy.

Conclusions: Although cigarette smoking is the main risk factor for developing COPD, recurring lung infections may have a synergistic effect. Sometimes recurrent infections are caused by a congenital malformation. Especially in adults who have had recurrent pneumonia since childhood.

Background: Body contouring surgery for the removal of the 11th and 12th ribs is undertaken for aesthetic appeal in female and transgender populations. The potential adverse effects of the surgery on lung function and respiratory muscle strength have not been previously studied. Therefore, this study aimed to determine the effects of 'Ant-waist' surgery on lung function and respiratory muscle strength in individuals who had undergone surgery.

Methods: This was a cross-sectional study with two groups, an Anti-waist group who had undergone surgery and an age and gender matched control group. Participants performed lung function tests to determine measurements of FEV1, FVC, FEV1/FVC, PEF, MIP, and MEP. Independent t-tests were performed to determine between-group differences in outcomes and Pearson's correlation coefficients determined the relationship between lung function and respiratory muscle strength, and number of years since surgery.

Results: There was a significant between-group difference in FEV1 (-0.83; 95%CI -1.30, -0.36; p<0.001), FEV1%pred. (-34.91; 95%CI -48.92, -20.90; p<0.001), FVC%pred. (-22.73; 95%CI -32.84, -12.62; p<0.001), PEF%pred. (-44.18; 95%CI -61.52, -26.84; p<0.001) and MEP (-68.27; -102.48, -34.07; p<0.001). There were significantly large, negative correlations (r>0.5) between the number of years after surgery and FEV1 (p=0.002), FEV1%pred. (p=0.0001); and PEF%pred. (p=0.032).

Conclusions: This study has identified that aesthetic surgery for the removal of ribs 11 and 12 had a significant adverse effect on lung function and respiratory muscle strength in Jordanian females. The potential adverse effects should be carefully explained by surgeons to patients considering the surgery.

Objective: A cough persisting beyond eight weeks is referred as chronic cough (CC) and is a common symptom of many respiratory conditions and non-respiratory conditions. The role of a speech language pathologist (SLP) in CC is emerging and this study aimed to profile the awareness and practice patterns of SLPs practicing in India.

Study design: Cross-sectional study.

Method: An online survey was used to profile the assessment, treatment and counselling practices in CC among SLPs working in India. It sought to identify the awareness levels among SLPs regarding their role and availability of behavioural interventions for CC. Only SLPs who dealt with CC could complete the entire survey while other SLPs, filled regarding awareness and availability of behavioural interventions.

Results: 127 eligible responses obtained from SLPs working across clinical settings in India were analysed. 75.59% (n=96) of them had not seen patients with CC in their career. 47.24% (n=60) of them were aware that behavioural interventions were available for CC. Thirty-one SLPs completed the entire survey and their practice patterns indicated that few clinicians used cough-specific protocols while largely relying on voice and swallowing related assessment and treatment for CC.

Conclusion: This survey the lack of awareness of SLPs' role in CC and that their practices are dominated by existing procedures for voice and swallowing disorders. Increasing the awareness of SLP's role in CC may increase the caseload of patients referred and expand the SLP's scope of practice. Development of guidelines in CC practice and inclusion in coursework/curriculum are future considerations.

Background: Primary ciliary dyskinesia (PCD) is a chronic respiratory illness that places significant strain on the healthcare system due to the complexity and expense of its diagnosis and treatment methods. The diagnostic process typically requires skilled technicians and an assortment of intricate, costly, and time-consuming approaches. Implementing screening tools can enhance efficiency by focusing the diagnostic process on those strongly suspected of having PCD. Tools such as the PCD Rule (PICADAR), North America Criteria Defined Clinical Features (NA-CDCF), the Clinical Index Score (CI), and the newly proposed CInew13 could potentially serve as useful screening tools. This study aims to examine the effectiveness of these tools individually, compare their performance against each other, and assess their results relative to prior research.

Methods: We conducted a diagnostic accuracy test on 83 Egyptian patients referred to Alexandria University Children's Hospital for potential PCD diagnosis between January 2015 and December 2022. The scores obtained from the screening tools were calculated and assessed.

Results: Of the initial group, 10 patients were ruled out because they fit other diagnostic parameters. Forty-three cases received a confirmed diagnosis, while 30 did not. Notably, the confirmed cases consistently scored higher on our screening tools than those that remained unconfirmed (p <.001, for all tested scores). We used receiver operating characteristic curves to assess and compare the effectiveness of each tool. The NA-CDCF had the smallest area under curve 0.736 (95% confiedence interval 0.619-0.832); in contrast, the CI score had the largest 0.898 (95% confidence interval 0.808-0.957).

Conclusion: All the tools tested were effective in identifying suitable patients for PCD testing at statistically significant levels. However, the PICADAR and NA-CDCF scores' performance did not significantly differ in the current study. The CI and CInew13 scores, on the other hand, outperformed both.

Background: Lung ultrasound (LUS) is a non-invasive point of care diagnostic tool used to assess the presence and severity of various lung disorders for more than two decades. Within the healthcare professionals are the respiratory therapists (RTs) who play a vital role in managing ventilated and other patients requiring respiratory support, but the incorporation of LUS into their scope of practice has not been well highlighted. This international cross-sectional survey was specifically designed to evaluate the knowledge, attitude, and practice of RTs with respect to LUS.

Methods: This observational cross-sectional study was conducted among RTs from different parts of the world using a questionnaire-based study tool. 514 RTs responded to all the questions and were considered for statistical analysis. Descriptive statistics, Analysis of variance, Fisher's exact, Chi-square, Bonferroni post-hoc analysis, and Binomial logistic regression analyses were performed to identify the significance of the data.

Results: From 22 countries, 514 RTs responded to the survey, with the major share from the middle eastern countries. Out of the 514 responders, 44.9% of the responders were in the age group of 23-30 years; 67.1% were bachelor's degree holders; and 40.9% of participants had more than 10 years of experience. The knowledge-based questions revealed that RTs with higher experience and academic qualification provided more positive responses. While in the attitude-related domain it is observed that standardized training in LUS helps them to enhance the current practice and to add LUS to the academic curriculum of respiratory therapy schools; however there remains barriers to practice LUS based on their responses. The practice-based questions revealed that RTs expect some additional seminars/workshops/webinars to be done on LUS frequently. More than half of the participants are found to be knowledgeable with a positive attitude and working towards the inclusion of LUS in respiratory therapy profession.

Conclusion: It is concluded that respiratory therapists have a positive attribute towards the inclusion of lung ultrasound in their clinical practice. Providing more structured training for professional respiratory therapists and including lung ultrasound modules in the respiratory therapy school curriculum may facilitate mastering their diagnostic skills, thereby expanding the scope of practice.
