Randomized Controlled Trial
BACKGROUND
Many persons with chronic obstructive pulmonary disease (COPD) or asthma have not received a diagnosis, so their respiratory symptoms remain largely untreated.
METHODS
We used a case-finding method to identify adults in the community with respiratory symptoms without diagnosed lung disease. Participants who were found to have undiagnosed COPD or asthma on spirometry were enrolled in a multicenter, randomized, controlled trial to determine whether early diagnosis and treatment reduces health care utilization for respiratory illness and improves health outcomes. Participants were assigned to receive the intervention (evaluation by a pulmonologist and an asthma-COPD educator who were instructed to initiate guideline-based care) or usual care by their primary care practitioner. The primary outcome was the annualized rate of participant-initiated health care utilization for respiratory illness. Secondary outcomes included changes from baseline to 1 year in disease-specific quality of life, as assessed with the St. George Respiratory Questionnaire (SGRQ; scores range from 0 to 100, with lower scores indicating better health status); symptom burden, as assessed with the COPD Assessment Test (CAT; scores range from 0 to 40, with lower scores indicating better health status); and forced expiratory volume in 1 second (FEV).
RESULTS
Of 38,353 persons interviewed, 595 were found to have undiagnosed COPD or asthma and 508 underwent randomization: 253 were assigned to the intervention group and 255 to the usual-care group. The annualized rate of a primary-outcome event was lower in the intervention group than in the usual-care group (0.53 vs. 1.12 events per person-year; incidence rate ratio, 0.48; 95% confidence interval [CI], 0.36 to 0.63; P<0.001). At 12 months, the SGRQ score was lower than the baseline score by 10.2 points in the intervention group and by 6.8 points in the usual-care group (difference, -3.5 points; 95% CI, -6.0 to -0.9), and the CAT score was lower than the baseline score by 3.8 points and 2.6 points, respectively (difference, -1.3 points; 95% CI, -2.4 to -0.1). The FEV increased by 119 ml in the intervention group and by 22 ml in the usual-care group (difference, 94 ml; 95% CI, 50 to 138). The incidence of adverse events was similar in the trial groups.
CONCLUSIONS
In this trial in which a strategy was used to identify adults in the community with undiagnosed asthma or COPD, those who received pulmonologist-directed treatment had less subsequent health care utilization for respiratory illness than those who received usual care.

INTRODUCTION
Cystic lung diseases are rare, with numerous differential diagnoses. Iconographic discovery consequently necessitates medical examinations in view of proposing an etiological orientation.
CASE REPORT
A 57-year-old woman consulted in pulmonology following fortuitous detection of a cystic lung disease on an abdominal CT scan. Complementary medical examinations did not allow orientation towards a particular diagnosis. During a follow-up consultation, the patient informed her pulmonologist of the recent detection of a monoallelic variant of a FAT4 gene in one of her daughters, who was suffering from edema of the lower limbs secondary to a disease of the lymphatic system. As our patient had a similar history, she likewise received a genetic analysis. A monoallelic variant not described in the genetic databases was observed, and considered as a probable pathogenic variant (class 4/5 on the pathogenicity scale of genetic variants).
CONCLUSION
After analyzing the available literature data, we raise questions about a possible link between this variant of the FAT4 gene, chronic lymphedema and our patient's cystic lung disease.

Observational Study
This study aims to investigate the effect of amantadine use on neurological outcomes and mortality in patients with severe traumatic brain injury (TBI) (Glasgow coma score [GCS] between 3 and 8) who have been followed up on mechanical ventilators in the intensive care unit (ICU). Data from the hospital's electronic records were retrospectively searched. Patients over 18 years of age, with severe brain trauma (GCS between 3-8), who were treated with endotracheal intubation and invasive mechanical ventilation at admission to the ICU, and who were treated with Amantadine hydrochloride at least once in the first week of follow-up were included in the study. To evaluate the patients' neurological outcomes, the GCS and FOUR scores were used. GCS and FOUR scores were recorded on the 1st, 3rd, and 7th days of the first week. In addition, the score difference between the 1st and 7th day was calculated for both scores. The patients were divided into 2 groups: those receiving amantadine treatment (Group A, n = 44) and the control group (Group C, n = 47). The median age of all patients was 39 (18-81) (P = .425). When Group A and Group C were compared, no statistically significant results were found between the 1st, 3rd, and 7th day GCS values (P = .474, P = .483, and P = 329, respectively). However, the difference in GCS values between day 1 and day 7 (∆ GCS 7-1) was statistically significant (P = .012). Similarly, when Group A and Group C were compared, no statistically significant results were found between the 1st, 3rd, and 7th day FOUR score values (P = .948, P = .471, and P = .057, respectively). However, the FOUR score values between day 1 and day 7 (∆ FOUR score 7-1) were statistically significant (P = .004). There was no statistically significant difference among the groups in terms of ICU length of stay, duration of non-ICU hospital stay, and length of hospital stay (P = .222, P = .175, and P = .067, respectively). Amantadine hydrochloride may help improve neurological outcomes in patients with severe TBI. However, further research is needed to investigate this topic.

INTRODUCTION
Self-management, as the most common method of chronic obstructive pulmonary disease (COPD) management, is not an isolated behaviour, but a set of physical, social, cultural, psychological and existential factors affecting it.
AIM
This study aimed to explore the facilitators and barriers to self-management in men with COPD in the unique social, cultural, political and economic context of Iran.
METHODS
This paper reports part of the findings of a qualitative grounded theory study aimed at exploring the process of self-management in Iranian men with COPD, which was conducted in Iran from January 2019 to July 2023. Participants included men with COPD, their family members and pulmonologists. The selection of participants in this research began with the purposeful sampling method. Data was collected using semistructured interviews. Data collection continued until the data saturation was achieved. A total of 15 interviews were conducted with nine patients, three family members of patients and three pulmonologists. The data was analysed using the constant comparative analysis method.
RESULTS
The findings of this study showed that knowledge, education, experience, family involvement and financial support are the factors that facilitate self-management. Factors related to deficits include lack of education, lack of treatment support, family cooperation deficit, financial problems, medication obtaining problems and factors related to disease impacts include specific nature of the disease, residual effect, comorbidity and factors related to negative patients characteristics include false beliefs, poor self-efficacy, feeling shame and non-adherence are barriers to self-management in men with COPD.
CONCLUSION
Based on results of this study, healthcare providers and health planners can strengthen the factors that facilitate self-management and weaken or remove the barriers to self-management, so that these patients use self-management strategies with maximum capacity to control the disease.

Severe chronic rhinosinusitis with nasal polyposis (CRSwNP) is a disabling airway disease that significantly impacts patients' lives through the severity of symptoms, the need for long-term medical treatment and the high risk of recurrence post-surgery. Biological agents targeting type 2 immune responses underlying the pathogenesis of CRSwNP have shown effectiveness in reducing polyp size and eosinophilic infiltrate, and in decreasing the need for additional sinus surgeries. However, despite recent progress in understanding and treating the disease, type 2 inflammation-driven severe CRSwNP continues to pose challenges to clinical management due to several factors such as persistent inflammation, polyp recurrence, heterogeneity of disease, and comorbidities. This article presents the findings of a scientific discussion involving a panel of ear, nose and throat (ENT) specialists and pulmonologists across Sweden and Finland. The discussion aimed to explore current management practices for type 2 inflammation-driven severe CRSwNP in the Nordic region. The main topics examined encompassed screening and referral, measurements of disease control, treatment goals, and future perspectives. The experts emphasized the importance of a collaborative approach in the management of this challenging patient population. The discussion also revealed a need to broaden treatment options for patients with type 2 inflammation-driven CRSwNP and comorbid conditions with shared type 2 pathophysiology. In light of the supporting evidence, a shift in the disease model from the presence of polyps to that of type 2 inflammation may be warranted. Overall, this discussion provides valuable insights for the scientific community and can potentially guide the future management of CRSwNP.

PURPOSE
The prevalence of airflow obstruction in Japan is 3.8%-16.9%. This epidemiological study based on a large database aimed to reassess the prevalence of airflow obstruction in Japan and the diagnosis rate of chronic obstructive pulmonary disease (COPD).
PATIENTS AND METHODS
We used data regarding claims from the health insurance union and health checkups provided by JMDC. The present study included a subgroup of individuals aged ≥40 years who underwent health checkups involving spirometry between January and December 2019. The study endpoints were the prevalence of airflow obstruction, COPD diagnosis rate, disease stage, and respiratory function test results.
RESULTS
Among 102,190 participants, 4113 (4.0%) had airflow obstruction. The prevalence of airflow obstruction was 5.3% in men and 2.1% in women. Among the study population, 6.8% were current smokers, while 3.4% were never or former smokers. Additionally, the prevalence of COPD increased with age. Approximately 8.4% of participants with airflow obstruction were diagnosed with COPD. Regarding the COPD diagnosis status, participants with airflow obstruction who were diagnosed with COPD were at a more advanced stage than those not diagnosed. Finally, patients diagnosed with COPD had significantly lower FEV/FVC and FEV (p < 0.0001; Wilcoxon rank sum test).
CONCLUSION
The epidemiological study based on a large database determined the COPD diagnosis rate related to airflow obstruction. The COPD diagnosis rate was extremely low among individuals who underwent health checkups, indicating the need for increased awareness about this medical condition. Moreover, primary care physicians should identify patients with suspected COPD and collaborate with pulmonologists to facilitate the early detection of COPD and enhance the COPD diagnosis rate.

Review
Allergic rhinitis (AR) is considered a trivial disease and is often self-treated with over-the-counter drugs and home remedies. However, AR is a contributing risk factor for asthma associated with complications, including chronic cough, eosinophilic esophagitis, and otitis media with effusion. In AR, inflammation is primarily mediated by histamines. Guidelines advise using second-generation oral H1 antihistamines as the primary treatment for AR. Second-generation H1 antihistamines strongly prefer the H1 receptor, limiting their ability to enter the central nervous system. Thus, they have minimal adverse effects. Among these H1 antihistamines, bilastine is highly specific for H1 receptors with a slight affinity for other receptors. It has a rapid and prolonged action, which reduces the need for frequent dosing and has better compliance. In the long term, bilastine is well-tolerated with minimal adverse effects. It is not associated with drug interactions, so dosage adjustment is unnecessary. Bilastine does not penetrate the brain and is nonsedating at 80 mg once daily. The low possibility of drug-drug interactions and pharmacokinetics of bilastine makes it suitable for elderly patients, even with compromised hepatic and renal function, without dose adjustment. This review comprehensively discusses the guidelines and the role of bilastine in treating AR. : Tiwaskar M, Vora A, Tewary K, Role of Bilastine in Allergic Rhinitis: A Narrative Review.

Review
Antisynthetase syndrome (ASyS) is now a widely recognized entity within the spectrum of idiopathic inflammatory myopathies. Initially described in patients with a triad of myositis, arthritis, and interstitial lung disease (ILD), its presentation can be diverse. Additional common symptoms experienced by patients with ASyS include Raynaud's phenomenon, mechanic's hand, and fever. Although there is a significant overlap with polymyositis and dermatomyositis, the key distinction lies in the presence of antisynthetase antibodies (ASAs). Up to 10 ASAs have been identified to correlate with a presentation of ASyS, each having manifestations that may slightly differ from others. Despite the proposal of three classification criteria to aid diagnosis, the heterogeneous nature of patient presentations poses challenges. ILD confers a significant burden in patients with ASyS, sometimes manifesting in isolation. Notably, ILD is also often the initial presentation of ASyS, requiring pulmonologists to remain vigilant for an accurate diagnosis. This article will comprehensively review the various aspects of ASyS, including disease presentation, diagnosis, management, and clinical course, with a primary focus on its pulmonary manifestations.

Burkholderia cenocepacia (B cenocepacia) is a gram-negative bacteria associated with significant morbidity and mortality following lung transplantation. Most US transplant programs consider B cenocepacia colonization to be an absolute contraindication to transplantation. This article argues that, if clinicians have good clinical reasons to expect poor outcomes for patients with B cenocepacia, then offering transplantation anyway is an abrogation of clinicians' fiduciary duties. This article also discusses other fiduciary obligations transplant programs might have to patients with B cenocepacia, such as referring to another transplant center, considering novel treatment options, and investigating how the infection's virulence factors stratify that patient's risk for poor transplant outcomes.
