Introduction: Medical thoracoscopy is a minimally invasive and safe procedure mostly performed for unexplained exudative pleural effusions but may be considered for pneumothorax (PNX)., Methods: This retrospective study included participants affected by PNX who underwent medical thoracoscopy with talc poudrage at a single academic hospital from 2008 to 2021. The primary endpoint was the observation of complete radiographical lung re-expansion and absence of air supply from the chest drain within 7 days of medical thoracoscopy. The secondary endpoint was achieving no recurrence of ipsilateral PNX at 24 months post-discharge., Results: A total of 95 patients affected by primary spontaneous PNX (PSP), secondary spontaneous PNX (SSP), iatrogenic, and traumatic PNX were enrolled. An additional procedure was required by 17.89% of patients, and only one patient with SSP required subsequent surgery. Recurrence of PNX occurred on the same side within 24 months after discharge in 9.47% of patients, with a median time to recurrence of 13.5 months. The PSP group was significantly more likely to achieve the primary endpoint. Pleural morphology was significantly associated with reaching the primary endpoint, while receiving a cumulative dose of talc greater than or equal to 4 g during hospitalization was associated with a lower risk of meeting it. Receiving a cumulative dose of talc greater than or equal to 4 g led in all cases to the achievement of the secondary endpoint. Patients with iatrogenic and traumatic PNX had an excellent prognosis in both the short- and long-term evaluation., Conclusion: Medical thoracoscopy is an effective procedure for treating PNX in the acute setting in selected cases while preventing long-term relapses. Large prospective clinical studies are needed to support and better define the role of medical thoracoscopy in current clinical practice., (© 2024. The Author(s).)

Patients with COVID-19 and metabolic-dysfunction associated fatty liver disease (MAFLD) appear to be at higher risk for severe manifestations, especially in the youngest decades. Our aim was to examine whether patients with MAFLD and/or with increased liver fibrosis scores (FIB-4) are at risk for severe COVID-19 illness, using a machine learning (ML) model. Six hundred and seventy two patients were enrolled for SARS-CoV-2 pneumonia between February 2020 and May 2021. Steatosis was detected by ultrasound or computed tomography (CT). ML model valuated the risks of both in-hospital death and prolonged hospitalizations (> 28 days), considering MAFLD, blood hepatic profile (HP), and FIB-4 score. 49.6% had MAFLD. The accuracy in predicting in-hospital death was 0.709 for the HP alone and 0.721 for HP + FIB-4; in the 55-75 age subgroup, 0.842/0.855; in the MAFLD subgroup, 0.739/ 0.772; in the MAFLD 55-75 years, 0.825/0.833. Similar results were obtained when considering the accuracy in predicting prolonged hospitalization. In our cohort of COVID-19 patients, the presence of a worse HP and a higher FIB-4 correlated with a higher risk of death and prolonged hospitalization, regardless of the presence of MAFLD. These findings could improve the clinical risk stratification of patients diagnosed with SARS-CoV-2 pneumonia., (© 2023. The Author(s).)

During the first two waves of the COVID-19 emergency in Italy, internal medicine high-dependency wards (HDW) have been organized to manage patients with acute respiratory failure (ARF). There is heterogeneous evidence about the feasibility and outcomes of non-invasive respiratory supports (NIRS) in settings outside the intensive care unit (ICU), including in patients deemed not eligible for intubation (i.e., with do-not-intubate, DNI status). Few data are available about the different NIRS modalities applied to ARF patients in the newly assembled internal medicine HDW. The main aim of our study was to describe a real-life experience in this setting of cure, focusing on feasibility and outcomes. We retrospectively collected data from COVID-19 patients with ARF needing NIRS and admitted to internal medicine HDW. Patients were treated with different modalities, that is high-flow nasal cannula (HFNC), continuous positive airway pressure (CPAP), or non-invasive mechanical ventilation (NIMV). Switching among different NIRS during the hospitalization and the success rate (weaning with the same NIRS) or failure (endotracheal intubation-ETI or in-hospital death) were recorded. Three hundred thirty four ARF patients (median age 74 years), of which 158 (54%) had a DNI status, were included. CPAP, NIMV, and HFNC's success rates were 54, 33, and 13%, respectively. Although DNI status was strongly associated with death (Gehan-Breslow-Wilcoxon test p < 0.001), an acceptable success rate was observed in these patients using CPAP (47%). Multivariate regression models showed older age (odds ratio-OR 4.74), chronic ischemic heart disease (OR 2.76), high respiratory rate after 24 h (OR 7.13), and suspected acute respiratory distress syndrome-ARDS (OR 21.1) as predictors of mortality risk or ETI. Our real-life experience shows that NIRS was feasible in internal medicine HDW with an acceptable success rate. Although DNI patients had a worse prognosis, the use of NIRS represented a reasonable chance of treatment., (© 2023. The Author(s).)

Background and Objective: Chronic obstructive pulmonary disease (COPD) and heart failure (HF) mutually increase the risk of being present in the same patient, especially if older. Whether or not this coexistence may be associated with a worse prognosis is debated. Therefore, employing data derived from the REPOSI register, we evaluated the clinical features and outcomes in a population of elderly patients admitted to internal medicine wards and having COPD, HF or COPD + HF., Methods: We measured socio-demographic and anthropometric characteristics, severity and prevalence of comorbidities, clinical and laboratory features during hospitalization, mood disorders, functional independence, drug prescriptions and discharge destination. The primary study outcome was the risk of death., Results: We considered 2,343 elderly hospitalized patients (median age 81 years), of whom 1,154 (49%) had COPD, 813 (35%) HF, and 376 (16%) COPD + HF. Patients with COPD + HF had different characteristics than those with COPD or HF, such as a higher prevalence of previous hospitalizations, comorbidities (especially chronic kidney disease), higher respiratory rate at admission and number of prescribed drugs. Patients with COPD + HF (hazard ratio HR 1.74, 95% confidence intervals CI 1.16-2.61) and patients with dementia (HR 1.75, 95% CI 1.06-2.90) had a higher risk of death at one year. The Kaplan-Meier curves showed a higher mortality risk in the group of patients with COPD + HF for all causes (p = 0.010), respiratory causes (p = 0.006), cardiovascular causes (p = 0.046) and respiratory plus cardiovascular causes (p = 0.009)., Conclusion: In this real-life cohort of hospitalized elderly patients, the coexistence of COPD and HF significantly worsened prognosis at one year. This finding may help to better define the care needs of this population., (© 2023. The Author(s).)

SARS-CoV-2 survivors may report persistent symptoms that resemble myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). We explored (a) ME/CFS-like symptom prevalence and (b) whether axonal, inflammatory, and/or lung changes may contribute to ME/CFS-like symptoms in SARS-CoV-2 survivors through clinical, neuropsychiatric, neuropsychological, lung function assessment, and serum neurofilament light chain, an axonal damage biomarker. ME/CFS-like features were found in 27% of our sample. ME/CFS-like group showed worse sleep quality, fatigue, pain, depressive symptoms, subjective cognitive complaints, Borg baseline dyspnea of the 6-min walking test vs. those without ME/CFS-like symptoms. These preliminary findings raise concern on a possible future ME/CFS-like pandemic in SARS-CoV-2 survivors., (© 2021. Journal of NeuroVirology, Inc.)

Coronavirus disease of 2019 (COVID-19) is associated with severe acute respiratory failure. Early identification of high-risk COVID-19 patients is crucial. We aimed to derive and validate a simple score for the prediction of severe outcomes. A retrospective cohort study of patients hospitalized for COVID-19 was carried out by the Italian Society of Internal Medicine. Epidemiological, clinical, laboratory, and treatment variables were collected at hospital admission at five hospitals. Three algorithm selection models were used to construct a predictive risk score: backward Selection, Least Absolute Shrinkage and Selection Operator (LASSO), and Random Forest. Severe outcome was defined as the composite of need for non-invasive ventilation, need for orotracheal intubation, or death. A total of 610 patients were included in the analysis, 313 had a severe outcome. The subset for the derivation analysis included 335 patients, the subset for the validation analysis 275 patients. The LASSO selection identified 6 variables (age, history of coronary heart disease, CRP, AST, D-dimer, and neutrophil/lymphocyte ratio) and resulted in the best performing score with an area under the curve of 0.79 in the derivation cohort and 0.80 in the validation cohort. Using a cut-off of 7 out of 13 points, sensitivity was 0.93, specificity 0.34, positive predictive value 0.59, and negative predictive value 0.82. The proposed score can identify patients at low risk for severe outcome who can be safely managed in a low-intensity setting after hospital admission for COVID-19.

Several factors worsen the prognosis of hospitalized patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPD). Little is known about the specific contribution of age. Study aim was to evaluate the impact of age on early mortality (90-days)., Methods: this observational prospective study considered hospitalized AECOPD patients. Three groups were created according to tertiles of age distribution: group 1 (≤ 67 years), group 2 (68-76 years) and group 3 (≥ 77 years). Baseline, clinical, microbiological, gas analysis and laboratory variables were collected at admission. The primary outcome was mortality at 90 days from admission. Multivariate regression models and receiver-operating characteristic (ROC) curves were used to evaluate the predictive power of age versus early mortality and adjusted for gender, comorbidities, staging and disease severity., Results: we enrolled 449 patients, 33 (7%) of whom died within 90 days from admission. Older patients were predominantly male, with more comorbidities, and higher dyspnoea grade and disease severity. The multivariate logistic regression demonstrated a significant predictive role of age as a continuous variable [odds ratio (OR) 1.05, 95% confidence interval (CI) 1.01-1.10; p = 0.046]. The Cox regression analysis found that group 2 [hazard ratio (HR) 6.6; 95% CI 1.5-28.8; p = 0.013], group 3 (HR 7.2; 95% CI 1.6-32.6; p = 0.010) and acute severe hypoxemia at admission (HR 2.7; 95% CI 1.2-6; p = 0.012) were independent significant predictors of mortality. The Kaplan-Meier curves showed a significant role of age in cumulative survival (Gehan-Breslow-Wilcoxon test p = 0.010). ROC curves highlighted 70 years as the best discriminating cut-off., Conclusions: age is a determinant of worse prognosis among hospitalized patients with AECOPD.

Liver cirrhosis is a major cause of morbidity and mortality worldwide, mainly due to complications of portal hypertension. In this article, we review the current understanding on the pathophysiology, the diagnostic criteria and the available therapeutic options for patients with emerging hepatic syndromes in cirrhosis, namely the hepatorenal, hepato-adrenal and hepatopulmonary syndrome. The hepatorenal syndrome is a well-recognized complication of advanced cirrhosis and is usually associated with an accelerated course to death unless liver transplantation is performed. The hepatopulmonary syndrome is often missed in the evaluation of patients with cirrhosis; however, early recognition is essential for the efficient management of individual patients. The hepato-adrenal syndrome, although not fully characterized, offers an exciting field for research and potential therapeutic interventions.

The role of pulmonary rehabilitation (PR) in COPD patients with lung hyperinflation has not yet been fully investigated. We retrospectively evaluated the effect of a standard PR course on exercise tolerance and symptoms according to the presence or absence of associated lung hyperinflation, as defined by lung function parameters in three Italian rehabilitation centres. In a cohort of 823 COPD patients (age 71 ± 8 years, FEV1 56 ± 18% pred.) we have systematically recorded: changes (∆) in 6-minute walking test (6MWD) as the primary outcome; dyspnoea (D); muscle fatigue (F); SO2nadir during effort; perceived breathlessness score (MRC); and specific health-related quality of life (SGRQ). Outcomes were compared between patients with lung hyperinflation (n = 283, LH) or without (n = 540 No-LH). Groups were comparable for age, body mass index, baseline exercise tolerance, and breathlessness. ∆-6MWD (+72 ± 47 vs. +62 ± 42 m, p < 0.05); ∆-D (-2.3 ± 1.7 vs. -1.9 ± 1.3 point, p < 0.05) and ∆-SO2nadir (+1.4 ± 3.0 and +0.5 ± 3.3 point, p < 0.05) were greater in LH than in No-LH. Using a multivariate linear regression model, ∆-6MWD in the LH group significantly correlated with lower functional residual capacity (p = 0.021) and baseline 6MWD (p = 0.004). Tolerance, gas exchange and perceived symptoms during effort are the parameters that gain a significant benefit from standard rehabilitation in COPD patients with a lung hyperinflation condition.

Chronic Obstructive Pulmonary Disease (COPD) has been recently recognized as a condition involving more than the lungs. The presence of common factors in COPD and in other chronic extra-pulmonary diseases, as well as the co-existence of these conditions in the same adult individual, supports the hypothesis of a shared pathogenetic pathway. We will here review the interplay between coexisting COPD and the metabolic syndrome (MS), based on the most updated knowledge. We will discuss this clinical condition from the definition, to the pathophysiology and to the clinical implications. Basically, MS is more likely to be present in a COPD patients, and increased levels of circulatory pro-inflammatory proteins from both the lung and adipose tissue coincide in these patients. The relative impact of the coexisting COPD and MS may depend on several factors: the presence of physical inactivity and of systemic inflammation related to a smoking habit, sedentary lifestyle, airway inflammation and obstruction, adipose tissue and inflammatory marker activation. More studies will be required to elucidate the association between COPD and MS and to formulate individualized management approaches for this specific disease phenotype.
