Diagnosis of lung cancer following emergency admission: Examining care pathways, clinical outcomes, and advanced NSCLC treatment in an Italian cancer Center.

Background: Lung cancer patients diagnosed following emergency admission often present with advanced disease and poor performance status, leading to suboptimal treatment options and outcomes. This study aimed to investigate the clinical and molecular characteristics, treatment initiation, and survival outcomes of these patients. Methods: We retrospectively analyzed data from 124 patients diagnosed with lung cancer following emergency admission at a single institution. Clinical characteristics, results of molecular analyses for therapeutic purpose, systemic treatment initiation, and survival outcomes were assessed. Correlations between patients' characteristics and treatment initiation were analyzed. Results: Median age at admission was 73 years, and 79.0 % had at least one comorbidity. Most patients (87.1 %) were admitted due to cancer-related symptoms. Molecular analyses were performed in 89.5 % of advanced non-small cell lung cancer (NSCLC) cases. In this subgroup, two-thirds (66.2 %) received first-line therapy. Median overall survival (OS) was 3.9 months for the entire cohort, and 2.9 months for patients with metastatic lung cancer. Among patients with advanced NSCLC, OS was significantly longer for those with actionable oncogenic drivers and those who received first-line therapy. Improvement of performance status during hospitalization resulted in increased probability of receiving first-line systemic therapy. Discussion: Patients diagnosed with lung cancer following emergency admission demonstrated poor survival outcomes. Treatment initiation, particularly for patients with actionable oncogenic drivers, was associated with longer OS. These findings highlight the need for proactive medical approaches, including improving access to molecular diagnostics and targeted treatments, to optimize outcomes in this patient population.

Prevalence of Long COVID Symptoms Related to SARS-CoV-2 Strains.

BACKGROUND: Few studies have assessed the differences of patterns of Long COVID (L-COVID) with regards to the pathogenetic SARS-CoV-2 strains. OBJECTIVES: To investigate the relationship between demographic and clinical characteristics of acute phase of infection and the persistence of L-COVID symptoms and clinical presentation across different SARS-CoV-2 strains. METHODS: In this observational-multicenter study we recorded all demographic and clinical characteristics, severity of infection, presence/persistence of symptoms of fatigue, dyspnoea and altered quality of life (QoL) at baseline and after 6 months, in a sample of Italian patients from Liguria between March 2020 and March 2022. RESULTS: 308 patients (mean age 63.2 years; 55.5% men) with previous COVID were enrolled. Obese patients were 21.2% with a significant difference in obesity prevalence across the second and third wave (p = 0.012). Treatment strategies differed between waves (p < 0.001): more patients required invasive mechanical ventilation in the first wave, more patients were treated with high-flow nasal cannula/non-invasive ventilation in the in the second and more patients were treated with oxygen-therapy in the fourth wave. At baseline, a high proportion of patients were symptomatic (dyspnoea and fatigue), with impairment in some QoL indicators. A higher prevalence of patients with pain, were seen in the first wave compared to later infections (p = 0.01). At follow-up, we observed improvement of dyspnoea, fatigue and some dimensions of QoL scale evaluation such as mobility, usual activities, pain evaluations; instead there was no improvement in remaining QoL scale indicators (usual care and anxiety-depression). CONCLUSIONS: There were no significant differences in the prevalence of the most frequent L-COVID symptoms, except for QoL pain domain that was especially associated with classical variant. Our results show substantial impact on social and professional life and usual care activities. These findings highlight the importance of multidisciplinary post COVID follow-up care including mental health support and rehabilitation program.

Pneumomediastinum following Endobronchial Ultrasound- Guided Transbronchial Needle Aspiration: A Case Report.

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is an effective and safe technique associated with a very low complication rate for the sampling of lymph nodes in those presenting with mediastinal and hilar adenopathy." We report a rare case describing the development of pneumomediastinum following EBUS-TBNA in a young patient with mediastinal lymphadenopathy secondary to non-Hodgkin's lymphoma. Conservative treatment led to spontaneous resolution of the pneumomediastinum. Pneumomediastinum is a rare but possible complication of EBUS-TBNA. Careful follow-up can reduce its severity and the associated morbidity.

Non-invasive mechanical ventilation in elderly patients: A narrative review.

The treatment of acute respiratory failure with non-invasive ventilation (NIV) as a first-line therapy is increasingly common in intensive care units. The reduced invasiveness of NIV leads to better outcomes than endotracheal intubation in carefully selected groups of patients. Furthermore, the use of NIV as a palliative treatment for respiratory failure and dyspnea has become increasingly common. NIV also has an impact on the use of "do not intubate" orders. In the present narrative review, we explore the use and outcome of NIV in elderly patients. To accomplish this, we reviewed the most recent available medical literature.

Severe respiratory failure as a presenting feature of an interstitial lung disease associated with anti-synthetase syndrome (ASS).

Anti-synthetase syndrome (ASS) is defined as a heterogeneous connective tissue disorder characterized by the association of an interstitial lung disease (ILD) with or without inflammatory myositis with the presence of anti-aminoacyl-tRNA-synthetase antibodies. ILD is one of the major extra-muscular manifestations of polymyositis and dermatomyositis. We report a case of a patient with dyspnea, cough, and intermittent fever as well as ILD associated ASS in the absence of muscular involvement. This patient was admitted to the emergency department with severe respiratory failure requiring non-invasive ventilation. Our patient's case demonstrates that the diagnosis of ASS may not be obvious. However, its diagnosis leads to appropriate and potentially life-saving treatment.

Is there an optimal level of positive expiratory pressure (PEP) to improve walking tolerance in patients with severe COPD? / ¿Cuál es el nivel óptimo de presión espiratoria positiva (PEP) capaz de mejorar la tolerancia a la deambulación de los pacientes con enfermedad pulmonar obstructiva cronica (EPOC) grave?

BACKGROUND: The application of positive expiratory pressure (PEP) devices during exercise had been proposed in order to counteract the pulmonary hyperinflation, reduce the dyspnea and thus increase the exercise tolerance in patients with severe chronic obstructive pulmonary disease (COPD). This randomized controlled crossover trial investigated the effect of two different levels of PEP (1 cmH2O and 10 cmH2O) on distance covered at 6minute walk test (6MWT) in patients with severe COPD. Secondary outcomes were the evaluation of PEP effects on physiological and pulmonary function variables. METHODS: Seventy-two severe COPD patients, referred to our hospitals as in and out patients, were recruited. A basal 6MWT without devices was performed on the first day, and then repeated with PEP 1 cmH2O (PEP1) and 10 cmH2O (PEP10), with a randomized crossover design. Slow and forced spirometries, including the inspiratory capacity measure, were repeated before and after each 6MWT. RESULTS: 50 patients (average age 69,92 year, mean FEV1 41,42% of predicted) concluded the trial. The 6MWT improved significantly among both PEP levels and baseline (323,8 mt at baseline vs. 337,8 PEP1 and 341,8 PEP10; p<.002 and p<.018, respectively). The difference between PEP10 and PEP1 did not reach the significance. No improvements were found in pulmonary function, symptoms and physiological variables after the 6MWT. CONCLUSIONS: In patients with severe COPD, the application of 1 cmH2O of PEP seems to improve the exercise tolerance as 10 cmH2O, with similar dyspnea. Further studies should investigate the effects of low levels of PEP on aerobic training programs.

Severe Respiratory Failure Due to Interferon Beta-Related Pulmonary Hypertension.

Pulmonary arterial hypertension (PAH) is an uncommon but devastating disease. There is increasing evidence of a correlation between interferon (IFN) use and PAH. Very few cases of PAH in patients treated with IFN are reported in literature. We report a case of a 47-year-old woman with previous diagnosis of multiple sclerosis treated with IFN ß-1a for 6 years, presenting severe respiratory failure (paO2/FiO2 228) because of pulmonary hypertension. The suspension of the drug along with the treatment of PAH improved the clinical picture allowing cessation of oxygen administration. Pathophysiological effects of IFN on endothelial vascular cells are discussed.

Streptococcus pneumoniae-associated pneumonia complicated by purulent pericarditis: case series.

OBJECTIVE: In the antibiotic era, purulent pericarditis is a rare entity. However, there are still reports of cases of the disease, which is associated with high mortality, and most such cases are attributed to delayed diagnosis. Approximately 40-50% of all cases of purulent pericarditis are caused by Gram-positive bacteria, Streptococcus pneumoniae in particular. METHODS: We report four cases of pneumococcal pneumonia complicated by pericarditis, with different clinical features and levels of severity. RESULTS: In three of the four cases, the main complication was cardiac tamponade. Microbiological screening (urinary antigen testing and pleural fluid culture) confirmed the diagnosis of severe pneumococcal pneumonia complicated by purulent pericarditis. CONCLUSIONS: In cases of pneumococcal pneumonia complicated by pericarditis, early diagnosis is of paramount importance to avoid severe hemodynamic compromise. The complications of acute pericarditis appear early in the clinical course of the infection. The most serious complications are cardiac tamponade and its consequences. Antibiotic therapy combined with pericardiocentesis drastically reduces the mortality associated with purulent pericarditis.

ResumoObjetivo:Na era dos antibióticos, a pericardite purulenta é uma entidade rara. Entretanto, ainda há relatos de casos da doença, associados a alta mortalidade, muitos deles atribuídos ao diagnóstico tardio. Aproximadamente 40-50% de todos os casos de pericardite purulenta são causados por bactérias gram-positivas, particularmente Streptococcus pneumoniae.Métodos:Relatamos quatro casos de pneumonia pneumocócica complicada por pericardite, com diferentes características clínicas e níveis de gravidade.Resultados:Em três dos quatro casos, a principal complicação foi tamponamento cardíaco. A pesquisa microbiológica (teste de antígeno urinário e cultura de líquido pleural) confirmou o diagnóstico de pneumonia pneumocócica grave complicada por pericardite purulenta.Conclusões:Em casos de pneumonia pneumocócica complicada por pericardite, o pronto diagnóstico é de extrema importância para evitar comprometimento hemodinâmico grave. As complicações da pericardite aguda aparecem no início do curso clínico da infecção. As complicações mais graves são tamponamento cardíaco e suas consequências. A antibioticoterapia com pericardiocentese reduz sobremaneira a mortalidade associada à pericardite purulenta.

Predictors of non-invasive ventilation failure in severe respiratory failure due to community acquired pneumonia.

BACKGROUND: Non-invasive ventilation (NIV) has been used for acute respiratory failure to avoid endotracheal intubation and intensive care admission. Few studies have assessed the usefulness of NIV in patients with severe community acquired pneumonia (CAP). The use of NIV in severe CAP is controversial because there is a greater variability in success compared to other pulmonary conditions. MATERIALS AND METHODS: We retrospectively followed 130 patients with CAP and severe acute respiratory failure (PaO2/FiO2 < 250) admitted to a Respiratory Monitoring Unit (RMU) and underwent NIV. We assessed predictors of NIV failure and hospital mortality using univariate and multivariate analyses. RESULTS: NIV failed in 26 patients (20.0%). Higher chest X-ray score at admission, higher heart rate after 1 hour of NIV, and a higher alveolar-arteriolar gradient (A-aDO2) after 24 hours of NIV each independently predicted NIV failure. Higher chest X ray score, higher LDH at admission, higher heart rate after 24 hours of NIV and higher A-aDO2 after 24 hours of NIV were directly related to hospital mortality. CONCLUSION: NIV treatment had high rate of success. Successful treatment is related to less lung involvement and to early good response to NIV and continuous improvement in clinical response.
