Pakistan has the world's fifth-largest prevalence of TB, with 276/100,000 cases in prevalence and a mortality of 34/100,000. Delayed diagnosis, disruptions in treatment continuity and a lack of awareness are the key issues leading to multidrug-resistant TB. The current study aimed to find out the determinants of delayed pulmonary TB in a rural district of Khyber Pakhtunkhwa Province, Pakistan. The cross-sectional study was conducted in six TB control program centers designated by the National TB Control Program from March to December 2024. Data were collected from 250 eligible patients, and after removal of incomplete questionnaires, the data of 229 patients were analyzed. The study was approved by the district TB officer, and participants' consent was obtained before data collection. A delay of >21 days was considered the cutoff point for delayed TB diagnosis. Among 229 patients, 51.1% were male and 48.9% female participants, with a mean age of 33.31±21.32 years. The mean diagnostic delay was 23.66±14.94 days. Descriptive analysis of data showed 52% of delayed TB diagnosis cases; 92.2% of the studied patients were from rural areas, in which 80% of delayed TB diagnosis cases were reported. Male gender [odds ratio (OR)=2.31], getting treatment from public hospitals (OR=4.13), age group 31-45 years (OR=3.10), presence of acute extrapulmonary symptoms of cough, fever, and weight loss (OR=2.84), perception that the symptoms will be relieved by oneself (OR=9.99), economic constraints (OR=6.58), and perception of the poor quality of healthcare services at hospitals (OR=7.32) were found to be significant factors of delayed TB diagnosis. Primary school- (OR=0.20), college- or university-level education (OR=0.42) and high-income groups (OR=0.39) were significant protective factors against delayed TB diagnosis. Marital status, occupation, residence, comorbidities, distance from healthcare facility, previous exposure to TB patients, fever, weight loss, chronic cough, hemoptysis, fear of diagnosis, fear of social isolation, and bad experience of the healthcare staff behavior were found to be non-significant factors for delayed TB diagnosis. The study only focused on delayed diagnosis and did not report healthcare system-related or total delay in tuberculosis management.

The findings revealed that levels of MMP-7 and MMP-8 were significantly elevated in both the periodontitis and ILD groups compared to healthy controls, while TIMP-1 did not show notable variation among groups. Clinical periodontal parameters were also higher in patients with ILDs as well as those with chronic periodontitis.

Community-based pulmonology care represents a potentially pivotal component of healthcare systems for the management of chronic and complex respiratory diseases. A national, anonymous, web-based survey was conducted among Italian pulmonologists working in territorial and community healthcare settings. The questionnaire explored organizational structures, clinical and diagnostic activities, availability of technological resources, care pathways, continuity of care, and integration with hospital services. A total of 168 valid questionnaires were collected and analyzed using descriptive methods. The survey revealed substantial heterogeneity across regions and healthcare organizations in terms of structural models, availability of diagnostic and interventional procedures, multidisciplinary teams, and access to telemedicine solutions. While several community services provide advanced outpatient and home-based respiratory care, significant gaps persist in standardized care pathways, timely access to functional respiratory diagnostics, and structured follow-up of chronic patients. Limitations in direct access to hospitalization pathways further contribute to fragmentation of care and potentially optimizable use of emergency medical services. This survey provides an initial, comprehensive overview of the current state of community-based pulmonology in Italy.

Reduced inhaler adherence is a well-recognized contributor to exacerbations and poorer outcomes in COPD. While self-management interventions are well established in stable COPD, their initiation during acute exacerbations has been inadequately explored. This randomized controlled trial, conducted in a South Indian tertiary hospital between July 2024 and May 2025, evaluated the effectiveness of a structured self-management program initiated during hospitalization for acute exacerbation of COPD. The intervention included individualized counseling, family engagement, structured telephonic follow-ups (weekly for 3 months, then monthly for 3 months), and scheduled outpatient reviews, while controls received standard care. Primary outcomes were inhaler adherence assessed by the Test of Adherence to Inhalers, health-related quality of life (HRQoL) measured with the St. George's Respiratory Questionnaire (SGRQ), and functional capacity assessed by the six-minute walk test. At six months, good inhaler adherence was observed in 66.7% of the intervention group compared to 10% of controls (p<0.001). The mean between-group difference in six-minute walk distance at six months was 92.8 meters [95% confidence interval (CI): 58.1 to 127.6; p<0.001], favoring the intervention group. HRQoL also improved significantly, with a mean between-group difference in SGRQ score of -38.2 (95% CI: -46.7 to -29.8; p<0.001).

In this narrative review, we summarize current evidence on the use of systemic corticosteroids as adjunctive therapy in pediatric CAP and illustrate their potential role through a representative clinical case. Available data from randomized trials, observational studies, and meta-analyses suggest that corticosteroids may shorten fever duration, improve oxygenation, and reduce length of hospital stay in selected pediatric patients, particularly those with hyperinflammatory features, parapneumonic effusions, or macrolide-refractory Mycoplasma pneumoniae infections. Some studies also indicate a reduced need for surgical intervention in complicated pneumonia. However, results remain heterogeneous, and current guidelines do not support routine corticosteroid use. Adverse effects are generally mild with short treatment courses and include hyperglycemia and transient behavioral changes. In the presented clinical case, adjunctive corticosteroid therapy was associated with rapid clinical and radiological improvement in a child with severe hyperinflammatory pleuropneumonia.

Ambulatory cardiac patients are highly vulnerable to DTPs primarily due to complex comorbidities, but the prevalence and specific drivers of these problems within chronic care settings in Ethiopia are poorly characterized. Therefore, this study aimed to determine the prevalence and predictors of DTPs among adult ambulatory CVD patients at Wolaita Sodo University Comprehensive Specialized Hospital from May 9 to July 8, 2022. We conducted an institution-based cross-sectional study among ambulatory cardiac patients receiving chronic care. Data were collected through structured patient interviews and comprehensive medical record reviews. DTPs were systematically identified and classified using Cipolle's validated methodology, adapted for the local patient population. Binary logistic regression was used to assess the associations between predictor variables and DTPs, followed by multiple logistic regression to control for potential confounders. Statistical significance was determined at p≤0.05, with 95% confidence intervals used to estimate precision of effect measures. Among 195 ambulatory CVD patients, hypertension (59.5%, n=116) and heart failure (47.2%, n=92) were the most prevalent conditions.
