Respiratory syncytial virus (RSV) plays a major part in causing lower respiratory tract infections in younger populations, especially in infants and pediatric patients, causing a higher rate of morbidity and mortality in the respective population, affecting 60% of the population globally. Typically, identifying the virus in the patient's respiratory secretions is important for laboratory validation of a clinically suspected RSV infection. Unfortunately, the only available preventive measure to lower the incidence for infants who are at high risk of RSV-induced hospitalization is palivizumab prophylaxis. Treatment strategies to manage RSV involve using an antiviral drug that is Ribavirin along with bronchodilators, nebulized adrenaline (epinephrine), and nebulized hypertonic saline. Providing patients with alternative treatment options like vitamin D-cathelicidin as well as probiotics and prebiotics can help reduce the intensity of the infection. This review article focuses on the epidemiology, clinical manifestation, prophylaxis, and available treatment options for RSV infections in infants, children, and young adults.

The use of ultrasound for pleural procedures is associated with a decreased risk of complications. Handheld ultrasounds allow for easier evaluation of the pleural space. Limited data exists for the use of such devices for pleural procedures. The primary objective of our study was to assess the effectiveness and safety of handheld ultrasound for pleural procedures. We performed a prospective observational study, including all consecutive patients who underwent pleural procedures using the handheld ultrasound between September 2021 and November 2023. A total of 332 pleural procedures were attempted with handheld ultrasound, of which 329 pleural procedures (99.1%) were successfully performed. The median volume of fluid drained was 500 (interquartile range: 300-800). Thoracentesis was performed in 127 patients (38.5%), tube thoracostomy in 179 patients (54.4%), and medical thoracoscopy in 23 patients (7.0%). Exudative pleural effusions were found in 264 patients (80.0%), of which 152 (46.2%) were determined to be due to infectious etiologies. A total of 4 (1.2%) patients had a complication due to the procedure. 2 patients (0.6%) had a pneumothorax, while 2 patients (0.6%) developed a hemothorax. A total of 101 patients had either low platelets (<50×109/L) or use of anti-platelet or anti-coagulant drugs. 128 patients (38.8%) were on positive pressure support during the pleural procedure. Our study shows that handheld ultrasounds are effective and safe for pleural procedures, including cases with septated pleural effusions and patients on anti-platelet or anti-coagulant drugs.

Tuberculosis (TB) is a major worldwide health problem, particularly in India, where it accounts for a quarter of infections. Adherence to the directly observed treatment, short-course (DOTS), which is necessary for TB treatment, is difficult in resource-limited circumstances. This study addressed the knowledge, attitude, and perceived barriers related to TB and DOTS adherence among patients and caregivers. A cross-sectional survey was undertaken at the selected TB clinics between November 2023 and March 2024. Purposive sample yielded 180 patients and 217 caregivers. Data were obtained using validated, self-structured questionnaires that assessed knowledge, attitude, and perceived barriers to TB and DOTS adherence. Statistical analysis was carried out with IBM SPSS version 23.0. The study found that caregivers had considerably greater TB knowledge than patients (p<0.05). Many patients misunderstood the cause of TB (50.6%) and embraced various misconceptions about the disease, such as TB spreading by shaking hands or sharing food, swimming in a holy river to cure diseases, and TB being the result of sin or karmic retribution. Distance to treatment facilities (95.6%), the necessity to take time off from work (91.7%), and social stigma (65.0%) were identified as the top three barriers to DOTS adherence. The study highlighted considerable gaps in knowledge, distant healthcare facilities, busy work schedules, and social stigma as barriers to TB treatment adherence in Deoghar, Jharkhand. Addressing these challenges via focused education and support activities is essential for enhancing DOTS adherence and TB treatment outcomes.

The respiratory symptoms experienced by patients with chronic obstructive pulmonary disease (COPD) are a burden on daily life. The objective of this study was to measure health-related quality of life (HRQoL) and comprehensively identify its associated factors in Moroccan COPD patients. A cross-sectional, randomized study was carried out in the city of Fes, Morocco, as part of the large multicenter Burden of Obstructive Lung Disease Study on people with COPD. Data collection was carried out using a questionnaire containing sociodemographic, clinical, and quality-of-life data. The diagnosis of COPD was based on spirometry, and quality of life was measured by the Short Form Survey (SF-12) questionnaire. Using multiple linear regression, we assessed the relationship between several sociodemographic and clinical factors and SF-12 mental and physical quality-of-life scores. A total of 107 patients were included, with a male predominance (63.6%) and the most common age category being 60 years and older (51.4%). Additionally, 46.7% of participants were classified as Global Initiative for Obstructive Lung Disease (GOLD) stage 1. The mean SF-12 mental component score was 41.32±9.18, and the mean SF-12 physical component score was 41.91±11.93. Multivariate analysis revealed that a greater mental HRQoL was associated with the male gender, a body mass index of 25 or higher, and GOLD stage 1, while a greater physical HRQoL was associated with the male gender, an age less than 60 years, absence of respiratory comorbidities, and GOLD stage 1. Our results show low scores of the mental and physical components of HRQoL in COPD patients in Morocco, suggesting the implementation of measures to reduce first the prevalence of the disease and then adopt an appropriate COPD management strategy to improve those people's quality of life.

Chronic obstructive pulmonary disease (COPD) presents as a multifaceted clinical landscape with various hematological manifestations. Among these, polycythemia and anemia pose distinct challenges. While the prevalence of polycythemia has decreased in recent years, anemia remains a prevalent concern, impacting patient outcomes. This study investigated the incidence and clinical characteristics of polycythemia in COPD patients, focusing on a diverse cohort in India. Methodological approaches included comprehensive evaluations of clinical parameters, pulmonary function, and hematological profiles. Results revealed significant variations in COPD severity, pulmonary function, and respiratory symptoms among patients with different hemoglobin levels. The findings shed light on the complex interplay between hematological variations and clinical manifestations in COPD, providing valuable insights for disease management strategies.

Low vitamin D levels are associated with different pulmonary diseases, such as chronic obstructive pulmonary disease, bronchial asthma, and obstructive sleep apnea. In this study, we aimed to assess the relation between vitamin D levels and COVID-19 severity. Positive COVID-19 patients were subjected to clinical examination, computed tomography of the chest, and laboratory investigations. Serum vitamin D level was measured and correlated with the severity and the clinical course of the disease. The study included 72 patients, classified into four groups according to the severity of the disease. There was a statistically significant difference between the four groups regarding age, lymphocyte count, serum vitamin D, C-reactive protein, and lactate dehydrogenase levels. Serum vitamin D levels can be correlated with COVID-19 severity and clinical course.

Systemic sclerosis (SSc) is a heterogeneous disease with a propensity to involve multiple organ systems. There is a significant proportion of these patients with interstitial lung disease (ILD) who are at risk of mortality and morbidity. There are limited available tools to assess the severity of parenchymal lung involvement and are subject to confounding factors, including the presence of pulmonary hypertension and concomitant smoking history. The diagnostic tools include careful clinical history, examination, thoracic imaging, and pulmonary function tests. One of the limitations of assessing disease severity in SSc-ILD is the lack of standardized definitions for disease activity and serum biomarkers to predict future progression. Although there has been significant progress in managing SSc-related ILD over the last couple of decades with a few randomized double-blind clinical trials assessing the role of immunosuppression (mainly Cyclophosphamide and Mycophenolate Mofetil), the efficacy of these therapies is at best modest and is associated with significant toxicities. Furthermore, Nintedanib has shown promise in reducing forced vital capacity decline in SSc-ILD and in progressive fibrotic-ILD of a range of etiologies. Data are emerging for therapies like Rituximab and Tocilizumab, and we are likely to see further evidence of similar drugs being efficacious in this disease cohort. A relatively simplified algorithm is proposed in this review to guide clinicians dealing with ILD and SSc. It is imperative that clinicians take a multi-disciplinary approach to managing this complex disease in a changing therapeutic landscape.

Systemic right ventricle (sRV) dysfunction is frequent in patients with congenitally corrected transposition of great arteries (cc-TGA) and those with dextro-transposition of great arteries (D-TGA) after Mustard/Senning operations. This condition should be identified promptly. We aimed to compare echocardiographic parameters with cardiac magnetic resonance (CMR)-derived parameters in patients with sRV and to evaluate their correlation with clinical variables and exercise capacity. Patients with cc-TGA and D-TGA after Mustard/Senning who underwent standard and advanced (speckle tracking and 3D) echocardiography and CMR (including feature-speckle tracking) were included. Clinical and imaging parameters were collected. Echocardiographic-derived right ventricle end-diastolic area and end-systolic area correlated with 3D echocardiographic-derived right ventricle end-diastolic and end-systolic volume (r=0.6, p=0.006 and r=0.8, p=0.002). 3D ejection fraction (EF) correlated with fractional area change and tricuspid annular plane systolic excursion (TAPSE) (r=0.8, p=0.001 and r=0.7, p=0.03). sRV global longitudinal strain (GLS) correlated with systemic atrial strain (sAS) (r=-0.6, p=0.01). CMR-derived EF correlated with CMR-derived GLS both endocardial and myocardial (r=-0.7, p=0.007 and r=-0.6, p=0.005). sRV areas as assessed by echo correlated with CMR-derived volumes (r=0.9, p=0.0001 for diastole and r=0.8, p=0.0001 for systole). Similarly, a correlation was found between sRV echo-derived GLS and CMR-derived GLS, both endocardial and myocardial (r=0.8, p=0.001 and r=0.7, p=0.01). The only imaging parameter that correlated with peak oxygen consumption was sAS (r=0.55, p=0.04). When comparing cc-TGA and D-TGA, the former showed better GLS-derived values as assessed by CMR (CMR-derived right ventricle endocardial longitudinal strain -23.2% versus -17.2%, p=0.002; CMR-derived right ventricle myocardial longitudinal strain -21.2% versus -16.7%; p=0.05), bigger systemic atrial area (20.2 cm2/m2 versus 8.4 cm2/m2, p=0.005) and higher TAPSE values (16.2 mm versus 12.2 mm, p=0.04). Echocardiography is valid to screen for sRV dilatation and function and to guide the timing for CMR. The investigation of atrial deformation imaging may help to better understand diastolic function. Patients with cc-TGA show better cardiac function compared to patients after atrial switch. Further investigations are needed to identify imaging parameters linked to exercise capacity.

Infective endocarditis (IE) is a life-threatening condition with high morbidity and mortality rates, making early diagnosis and intervention crucial. This report details the case of a 47-year-old male with a history of mechanical prosthetic aortic valve replacement, presenting with pyrexia and diagnosed with aortic bioprosthetic endocarditis leading to a massive aortic pseudoaneurysm. This shows that 3D transesophageal echocardiography is much more useful than regular 2D imaging for finding problems with IE, which makes surgical planning and intervention more precise.
