Synergistic properties of linezolid against Enterococcus spp. isolates: a systematic review from in vitro studies.

PURPOSE: Vancomycin-resistant enterococci (VRE) are a leading cause of hospital-acquired infections with limited therapeutic options. Combination of at least two antimicrobials is a possible strategy to obtain rapid and sustained bactericidal effects and overcome the emergence of resistance. We revised the literature on linezolid synergistic properties from in vitro studies to assess its activity in combination with molecules belonging to other antibiotic classes against Enterococcus spp. METHODS: We performed a systematic review of the literature from three peer-reviewed databases including papers evaluating linezolid synergistic properties in vitro against Enterococcus spp. isolates. RESULTS: We included 206 Enterococcus spp. isolates (92 E. faecalis, 90 E. faecium, 2 E. gallinarum, 3 E. casseliflavus, 19 Enterococcus spp.) from 24 studies. When an isolate was tested with different combinations, each combination was considered independently for further analysis. The most frequent interaction was indifferent effect (247/343, 72% of total interactions). The highest synergism rates were observed when linezolid was tested in combination with rifampin (10/49, 20.4% of interactions) and fosfomycin (16/84, 19.0%, of interactions). Antagonistic effect accounted for 7/343 (2.0%) of total interactions. CONCLUSION: Our study reported overall limited synergistic in vitro properties of linezolid with other antibiotics when tested against Enterococcus spp. The clinical choice of linezolid in combination with other antibiotics should be guided by reasoned empiric therapy in the suspicion of a polymicrobial infection or targeted therapy on microbiological results, rather than on an intended synergistic effect of the linezolid-based combination.

Effectiveness and safety of Argon Plasma Coagulation in patients with haemoptysis caused by an endobronchial malignancy.

BACKGROUND: Patients with central neoplasms and haemoptysis show low survival rates. Symptom control without recurrence 48 hours after bronchoscopic interventions may improve the prognosis of these patients. Bronchoscopic Argon Plasma Coagulation (APC) is a useful technique for endobronchial management of haemoptysis in patients with central malignancies. Nevertheless, limited data are available in the literature on its efficacy and safety and the main predictors of success are still unclear. MATERIALS AND METHODS: An observational, prospective, single-center cohort study was carried out to assess the efficacy (i.e. immediate bleeding cessation without recurrence during the following 48 hours) of bronchoscopic APC in the treatment of patients with haemoptysis caused by endobronchial malignancies and the main predictors of success. RESULTS: A total of 76 patients with median age 75 years (IQR: 65-79) were enrolled. 67 (88.2%) patients had bleeding cessation without recurrence 48 hours after bronchoscopic APC. A low rate of non-serious adverse events (5.3%) was recorded and a low (7.6%) recurrence rate of haemoptysis at 3.5 months after the procedure was also shown. No clinical, demographic and endoscopic variables related to a successful procedure at 48 hours were found. CONCLUSIONS: This study demonstrates that bronchoscopic APC is an effective procedure in the treatment of patients with haemoptysis caused by endobronchial malignancies, regardless of the clinical characteristics of the patients, the endoscopic and histological features of the neoplasm and the severity of the symptom. Furthermore, it shows a low rate of complications and long-term efficacy in bleeding control.

Monitoring COPD patients: systemic and bronchial eosinophilic inflammation in a 2-year follow-up.

BACKGROUND: High blood eosinophils seem to predict exacerbations and response to inhaled corticosteroids (ICS) treatment in patients with chronic obstructive pulmonary disease (COPD). The aim of our study was to prospectively evaluate for 2 years, blood and sputum eosinophils in COPD patients treated with bronchodilators only at recruitment. METHODS: COPD patients in stable condition treated with bronchodilators only underwent monitoring of lung function, blood and sputum eosinophils, exacerbations and comorbidities every 6 months for 2 years. ICS was added during follow-up when symptoms worsened. RESULTS: 63 COPD patients were enrolled: 53 were followed for 1 year, 41 for 2 years, 10 dropped-out. After 2 years, ICS was added in 12/41 patients (29%) without any statistically significant difference at time points considered. Blood and sputum eosinophils did not change during follow-up. Only FEV1/FVC at T0 was predictive of ICS addition during the 2 year-follow-up (OR:0.91; 95% CI: 0.83-0.99, p = 0.03). ICS addition did not impact on delta (T24-T0) FEV1, blood and sputum eosinophils and exacerbations. After 2 years, patients who received ICS had higher blood eosinophils than those in bronchodilator therapy (p = 0.042). Patients with history of ischemic heart disease increased blood eosinophils after 2 years [p = 0.03 for both percentage and counts]. CONCLUSIONS: Blood and sputum eosinophils remained stable during the 2 year follow-up and were not associated with worsened symptoms or exacerbations. Almost 30% of mild/moderate COPD patients in bronchodilator therapy at enrollment, received ICS for worsened symptoms in a 2 year-follow-up and only FEV1/FVC at T0 seems to predict this addition. History of ischemic heart disease seems to be associated with a progressive increase of blood eosinophils.

Tailored treatment for tuberculosis in transgender individuals: a call for a patient-centered approach from a large Italian cohort.

Tuberculosis (TB) diagnosis and management in special populations remain challenging. Data about TB and transgender individuals is scarce, and strategies aimed at reducing the TB burden in this at-risk group are needed. We conducted an observational monocentric study from a national reference center for TB, including transgender individuals with active TB in a low-TB burden country (Italy), over 34 years (1990-2023). Sixty-six transgender males and two transgender females (median age 30 years, interquartile range 26-38 years, 65 migrants) were included. Most patients (38/66, 57.6%) lived in poor social conditions. 65.2% (43/66) of patients were people living with HIV. Multidrug- and rifampicin-resistant tuberculosis and isoniazid-resistant TB were diagnosed in five (7.6%) and three (4.5%) patients, respectively. The overall treatment success rate was 72.7% (48/66 patients), with differences observed according to social conditions. Our study highlights the need for a tailored approach to increase treatment success in this at-risk population.

Xpert MTB/RIF in the Diagnosis of Mediastinal Tuberculous Lymphadenitis by Endoscopic Ultrasound-Guided Needle Aspiration Techniques: A Systematic Review and Meta-Analysis.

BACKGROUND: Lymphadenopathy is one of the most prevalent clinical manifestations of extrapulmonary tuberculosis. Endosonography is the recommended technique in the diagnostic work-up of mediastinal lymphadenopathies. Xpert MTB/RIF assay is a self-contained cartridge-based fully automated DNA testing platform which can accurately detect both tuberculosis and mycobacterial resistance to rifampicin. A few studies assessed its accuracy for mediastinal lymph node aspirates collected using endosonography. A systematic review of observational studies was performed to provide a pooled estimate of sensitivity and specificity of Xpert MTB/RIF in the diagnosis of mediastinal tuberculous lymphadenitis using endoscopic ultrasound-guided needle aspiration techniques. METHODS: A search of the scientific evidence was carried out using PubMed, Embase, and Scopus. Articles describing observational studies on Xpert MTB/RIF in the diagnosis of mediastinal tuberculous lymphadenitis using endoscopic ultrasound-guided needle aspiration techniques were selected. RESULTS: Eight studies met the inclusion criteria. The overall pooled sensitivity was 61% (95% CI = 55-68%; I2 = 66.3%; p = 0.004), overall pooled specificity was 89% (95% CI = 85-91%; I2 = 90.1%; p < 0.0001). Area under the sROC curve was 0.68. Only one study reported data on rifampin resistance detection and showed a sensitivity of 83.3% and a specificity of 16%. CONCLUSIONS: Xpert MTB/RIF shows a good accuracy in the diagnosis of mediastinal mycobacterial lymphadenitis by endosonographic needle aspiration techniques. It should be always recommended for suspected mediastinal tuberculosis.

Observational, Multicenter Study on the Efficacy, Tolerability, and Safety of Nintedanib in Patients with Idiopathic Pulmonary Fibrosis Older than 80 Years.

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) primarily affects old patients. Old age is a predictor of mortality. Nintedanib, the only antifibrotic drug approved in Italy for patients aged >80 years, can slow the progression of IPF by reducing the rate of decline in forced vital capacity (FVC) and the risk of exacerbations. OBJECTIVES: The primary aim of the study was to compare the decline of FVC after 12 months of nintedanib in patients aged >80 years versus younger patients. Differences related to other functional data, safety, tolerability, hospitalizations, exacerbations, and mortality were evaluated. METHODS: An observational, retrospective, multicenter study was carried out in Italy. RESULTS: 159 (122 [76.7%] males) patients were recruited: 106 (66.7%) aged ≤80 years and 53 (33.3%) aged >80 years. FVC decline after 12 months of therapy was not significantly different (-45 mL [-170; 75] vs. -20 mL [-138; 110] mL; p: 0.51). No differences were found for other functional data. Diarrhea was the most frequent adverse event (AE). Rate and type of any AEs, permanent/temporary dose reduction, or drug discontinuation were not significantly different between patients aged ≤80 vs. >80 years. Furthermore, acute exacerbations, hospitalization, and mortality were not significantly different. CONCLUSIONS: Nintedanib is effective and safe in patients with IPF aged >80 years, and no significant differences were found when clinical outcomes were compared with those of younger patients. Thus, older age should not be a barrier for the early prescription of antifibrotic treatment in IPF patients.

Bronchoscopy in the post-acute phase of COVID-19: an observational study.

BACKGROUND: Bronchoscopy is a useful technique adopted in the management of patients with COVID-19. 10-40% of COVID-19 survivors experience persistent symptoms. A comprehensive description of the utility and safety of bronchoscopy in the management of patients with COVID-19 sequelae is lacking. The aim of the study was to evaluate the role of bronchoscopy in patients with suspected post-acute sequelae of COVID-19. METHODS: An observational, retrospective study was carried out in Italy. Patients requiring bronchoscopy for suspected COVID-19 sequelae were enrolled. RESULTS: 45 (21, 46.7%, female) patients were recruited. Bronchoscopy was more frequently indicated for patients with a previous critical disease. The most frequent indications were tracheal complications, mostly performed in patients who were hospitalized during the acute phase than treated at home (14, 48.3% VS. 1, 6.3%; p-value: 0.007) and persistent parenchymal infiltrates, more frequent in those treated at home (9, 56.3% VS. 5, 17.2%; p-value: 0.008). 3 (6.6%) patients after the first bronchoscopy required higher oxygen flow. Four patients were diagnosed with lung cancer. CONCLUSION: Bronchoscopy is a useful and safe technique in patients with suspected post-acute sequelae of COVID-19. The severity of acute disease plays a role in the rate and indications of bronchoscopy. Endoscopic procedures were mostly performed for tracheal complications in critical, hospitalized patients and for persistent lung parenchymal infiltrates in mild-moderate infections treated at home.

Evaluation of Human Papilloma Virus (HPV) Genotyping and Viral Load Determination as Diagnostic Biomarkers of Cervical Cancer Risk.

HPV testing in cervical cancer screening programs offers the possibility of introducing molecular standardized biomarkers for the triage of HPV-positive women. This study aimed to evaluate the role of HPV genotyping and viral load as possible diagnostic biomarkers of high-grade cervical lesions (CIN2+) by performing a preliminary evaluation of a new HPV test. Cervical specimens were obtained from 200 women referred for a colposcopy. Samples were tested using both Anyplex™ II HR-HPV as well as OncoPredict HPV® Screening (SCR) and quantitative typing (QT). Using a cycle threshold cutoff (Ct) of 36.8 for the SCR assay and 1.27 log10 (viral copies/104 cells) for the QT assay, relative clinical sensitivity for CIN2+ and relative clinical specificity for CIN2- as compared to Anyplex™ II HR-HPV were, respectively, 0.92 and 1.00 for SCR and 1.35 and 1.24 for QT. The distribution of high-risk HPV (HR-HPV) genotypes (p = 0.009) as well as the viral copy numbers (CIN2-: 3.7 log10 (viral copies/104 human cells); CIN2+: 4.3 log10 (viral copies/104 human cells); p = 0.047) were found to differ in women with high- and low-grade cervical lesions, suggesting a possible role of HPV genotyping and normalized viral load as potential biomarkers to identify women at increased risk of cervical lesions.

Smoking and combined oral contraceptives should be considered as an independent variable in sex and gender-oriented studies.

The influence of sex combined with smoking and combined oral contraceptives (COC) use on atherogenic indexes is scarcely studied. Thus, traditional lipid parameters were measured, and non-traditional atherogenic indexes were calculated in a young and healthy population of men, COC-free women, and COC users. Total cholesterol (TChol), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and HDL/LDL ratio were lower in men, while triglycerides (TG)/HDL ratio, atherogenic index of plasma (AIP), Castelli's Risk Index I (CRII) and CRI-II, atherogenic coefficient (AC), creatinine, creatinine clearance, and estimated glomerular filtration rate (eGFR) were higher in men. The use of COC modified TChol, HDL, TG, TG/HDL, and AIP which had significantly higher values in COC users. In addition, TG were also increased in COC users in comparison with men. Smoking reduced sexually divergent parameters: BMI, TG, HDL/LDL, TG/HDL, AIP, CRII, CRI-II, and AC became similar among the three cohorts, losing the reported sex differences. Smoking also reduced differences in TChol, HDL, TG, and AIP between COC-free women and COC users, but it does not affect CRII, CRI-II, creatinine, creatinine clearance, and eGFR, underlining that COC users and COC-free women have to be considered two different populations. Our results represent a complex landscape suggesting that for both sexes smoking should be an independent variable in medical studies. Moreover, in women, the use of COC evidenced two different cohorts. Thus, more variables should be considered during a single study indicating that sex, smoking, and COC should be studied together to get a picture of the real-life context.

Relationship between electrocardiographic interatrial blocks and echocardiographic indices of left atrial function in acute heart failure.

The presence of an interatrial block (IAB) on surface ECG should be considered as a hallmark of atrial electrical remodelling. This is often accompanied by morphological abnormalities. We aimed to investigate the frequency of IAB and its relationship with the echocardiographic indices of left atrial (LA) remodelling in patients hospitalised with acute HF. Ninety-four consecutive HF patients underwent 12-lead ECG, transthoracic echocardiogram including a detailed study of the LA, and blood tests (including NT-proBNP) on the same day. Thirty-six patients were excluded from the analysis because of atrial fibrillation or rhythms other than sinus. Twenty-eight over 58 (48%) were males. Median age was 72 (IQR 60-82) years. The majority of patients (72%) were diagnosed as having an HF with reduced ejection fraction. Overall, 27 (46%) patients presented with an advanced III or IV NYHA functional class. Median plasma NT-proBNP was 3046 (IQR 1066-5460) pg/ml. Nearly, all the enrolled patients (90%) showed LA dilation. Nineteen patients (33%) presented with advanced IAB. There was a trend toward a more advanced age in patients with advanced IAB (median age 79 vs 68, p = 0.051). Moreover, they were more frequently treated with anticoagulants (42% vs 13%, p = 0.01), and they exhibited greater LA structural and functional remodelling documented by larger area (28 vs 26 cm2, p = 0.04) and greater minimum LA volume index-LAVi (43 ± 16 vs 36 ± 10, p = 0.04). Advanced IAB resulted to be an independent determinant of LA area (Beta 3.49 (0.37-6.60), p = 0.03) and minimum LAVi (Beta 7.22 (0.15-14.30), p = 0.045), and vice versa. LA electrical and structural remodelling is highly prevalent in a non-selected cohort of patients with acute HF. Advanced IAB on surface ECG is present in a high percentage of cases. Patients with advanced IAB tend to be older, and they exhibit higher degrees of LA structural and functional remodelling.

Analysis of Patients with Asthma and Mixed Granulocytic Inflammatory Pattern in Sputum.

BACKGROUND: Patients with asthma usually present airway inflammation classified as eosinophilic, neutrophilic, mixed granulocytic, and paucigranulocytic pattern according to sputum inflammatory cells. OBJECTIVE: The aim of the study was to analyze clinical and biological characteristics of patients with asthma and mixed granulocytic pattern in comparison with the other groups. METHODS: Induced sputum was used to assess airway inflammation; lung function was evaluated as well as blood leukocytes and disease control. History of comorbidities was collected. RESULTS: We retrospectively analyzed 231 subjects with asthma; patients with mixed granulocytic pattern were more frequently male compared with paucigranulocytic subjects, older than eosinophilic and paucigranulocytic patients with increased number and vitality of sputum cells compared to eosinophilic and paucigranulocytic patients and higher cumulative illness rating score, related to increased age. Smoking history, age of disease onset, and ICS treatment were not associated with higher mixed granulocytic pattern occurrence. Subjects with neutrophilic inflammation (mixed granulocytic and neutrophilic patterns considered altogether) were more frequently obese. In subjects under 67 years of age (median of the enrolled subjects), arterial hypertension was the only comorbidity more frequent in mixed granulocytic than in the other groups. 137/231 subjects were re-valuated during follow-up. Lung function of patients with mixed granulocytic, neutrophilic, and paucigranulocytic patterns improved less than that of eosinophilic patients. CONCLUSION: Aging and presence of comorbidities, in particular obesity and hypertension, are characteristics of patients with asthma and mixed granulocytic pattern. They could respond less well to treatment than eosinophilic patients.

Accuracy and Predictors of Success of EUS-B-FNA in the Diagnosis of Pulmonary Malignant Lesions: A Prospective Multicenter Italian Study.

BACKGROUND: The role of endoscopic ultrasound with bronchoscope fine-needle aspiration (EUS-B-FNA) in the diagnosis of suspected malignant pulmonary lesions adjacent to the esophagus has been poorly investigated. The aim of the present study was to assess the accuracy of EUS-B-FNA for the diagnosis and molecular profiling of paraesophageal pulmonary lesions, as well as its predictors of success. MATERIALS AND METHODS: Patients who underwent EUS-B-FNA for the diagnosis of paraesophageal lesions were consecutively enrolled in four Italian centers. Demographic, clinical, procedural, pathological, and molecular characteristics of the malignant samples were collected. The primary outcome was the diagnostic accuracy for pulmonary malignancies. Secondary outcomes were diagnostic yield and predictors of success for diagnosis and molecular profiling. RESULTS: 107 adult patients (60 [56.1%] males; median (interquartile range) age: 69 [60-70] years) were enrolled. The diagnostic accuracy of EUS-B-FNA was 95.3% in the overall cohort and 95.2% in the 99 patients with a final diagnosis of malignancy. Neither clinical nor procedural variables significantly affected the diagnostic accuracy, whereas rapid on-site evaluation (ROSE), performed by pathologists or trained pulmonologists, was a strong predictor for a complete molecular profiling (OR [95% CI]: 12.9 [1.2-137.4]; p value: 0.03). CONCLUSION: EUS-B-FNA is a safe and accurate method for the diagnosis of paraesophageal pulmonary lesions. The presence of ROSE is relevant for a complete molecular profiling in this selected cohort of patients with advanced lung cancer.

The challenge of infectious diseases consultations in the emergency department: an Italian nationwide survey.

Diagnosis and management of infectious diseases (ID) at the emergency department (ED) are challenging due to the peculiar setting and the available diagnostic tools. The involvement of an ID consultant has been described to improve clinical outcomes and antimicrobial stewardship (AMS) programs. An online survey was sent to 100 Italian Departments of Infectious Diseases affiliated with the Italian Society of Infectious Diseases and Tropical Medicine (SIMIT). The primary objective of our study was to describe the characteristics of ID services in Italian EDs to identify possible challenges and shortcomings and provide tips to improve the management of patients. Secondary objectives included the evaluation of diagnostic capability and the management of patients with suspected or confirmed ID. Seventy-six out of the 100 SIMIT centers, 32 (42.1%) of which were teaching hospitals, answered the survey. In 62 (82.7%) centers, consultations were performed by the IDs specialist on call. In 29 (38.2%) centers, there was a formal AMS program, and 32 (42.7%) had protocols for antibiotic use in the ED. Microbiological tests to be performed before starting antibiotic treatment in the ED were clearly defined in 44 (57.9%) hospitals. This survey highlighted several challenges in the current organization of ID consultations in Italian EDs.

Pharmacodynamic analysis of a fluid challenge with 4 ml kg-1 over 10 or 20 min: a multicenter cross-over randomized clinical trial.

PURPOSE: A number of studies performed in the operating room evaluated the hemodynamic effects of the fluid challenge (FC), solely considering the effect before and after the infusion. Few studies have investigated the pharmacodynamic effect of the FC on hemodynamic flow and pressure variables. We designed this trial aiming at describing the pharmacodynamic profile of two different FC infusion times, of a fixed dose of 4 ml kg-1. METHODS: Forty-nine elective neurosurgical patients received two consecutive FCs of 4 ml kg-1 of crystalloids in 10 (FC10) or 20 (FC20) minutes, in a random order. Fluid responsiveness was defined as stroke volume index increase ≥ 10%. We assessed the net area under the curve (AUC), the maximal percentage difference from baseline (dmax), time when the dmax was observed (tmax), change from baseline at 1-min (d1) and 5-min (d5) after FC end. RESULTS: After FC10 and FC20, 25 (51%) and 14 (29%) of 49 patients were classified as fluid responders (p = 0.001). With the exception of the AUCs of SAP and MAP, the AUCs of all the considered hemodynamic variables were comparable. The dmax and the tmax were overall comparable. In both groups, the hemodynamic effects on flow variables were dissipated within 5 min after FC end. CONCLUSIONS: The infusion time of FC administration affects fluid responsiveness, being higher for FC10 as compared to FC20. The effect on flow variables of either FCs fades 5 min after the end of infusion.

Heart rate recovery in adult individuals with asthma.

Slow heart rate recovery (HRR) after exercise is a predictor of overall mortality in individuals with and without cardiovascular or respiratory disorders. No data on adults with asthma are available. The purpose of the study is to evaluate the prevalence of slow HRR in these individuals as compared with those with chronic obstructive pulmonary disease (COPD). We performed a retrospective analysis of baseline characteristics and physiological response to the six-minute walking distance test of stable individuals with asthma or COPD. Slow HRR was defined as HRpeak - HR at 1 minute after end exercise <12 bpm. Individuals with asthma walked significantly longer (median (IQR): 455 (385-512) vs 427 (345-485) meters; p=0.005) with a lower prevalence of slow HRR (30.3% vs 49.0%, respectively: p<0.001) than those with COPD. Individuals with asthma and slow HRR were older and walked less than those with normal HRR, without any difference in airway obstruction or in disease severity. Multivariate analysis showed that only the difference HRpeak - baseline HR (∆HR), was a predictor of slow HRR in both groups. More than 30% of adult individuals with asthma may show slow HRR. Only exercise ∆HR but no baseline characteristic seems to predict the occurrence of slow HRR.

Safety and feasibility of physiotherapy in ICU-admitted severe COVID-19 patients: an observational study.

Early physiotherapy could play an important role in the management of severe COVID-19 subjects with consequences of prolonged ICU stay, although its effectiveness is still unclear. Aim of this study is to describe physiotherapy performed in severe COVID-19 patients and to evaluate its safety and feasibility. Consecutive adults with confirmed SARS-CoV-2 infection, admitted to the ICU, needing invasive mechanical ventilation for >24 hours and receiving early physiotherapy, have been enrolled. Adverse events occurred during physiotherapy sessions and timing and type of physiotherapy delivered were analysed, to identify the interventions most frequently performed and to determine the time taken to first mobilize, stand and walk. Functional and clinical assessment of patients was also performed at hospital discharge. Eighty-four severe COVID-19 subjects were enrolled. Few minor adverse events were recorded. Active mobilization was promoted over passive mobilization and independence in daily life activities was supported. Time interval from patients' intubation to the first physiotherapy treatment was 13 days and to walking was 27 days. Forty-eight (57.1%) subjects returned at home, whereas 29 (34.5%) were discharged to in-patient rehabilitation. Patients with tracheostomy experienced a delay in time from ICU admission until sit out of bed and ambulation, if compared with subjects without tracheostomy, although no differences were found in 6MWT and 1m-STST performances. This study reporting early physiotherapy during pandemic suggests that this intervention is feasible and safe for severe COVID-19 subjects, as well as healthcare workers, although delayed compared to other critically ill patients.

Long-term prognostic outcomes in patients with haemoptysis.

BACKGROUND: Haemoptysis is a challenging symptom that can be associated with potentially life-threatening medical conditions. Follow-up is key in these patients to promptly detect new or misdiagnosed pathologic findings. Few prospective studies have evaluated long-term prognostic outcomes in patients with haemoptysis. Furthermore, the role played by antiplatelet and anticoagulant drugs on mortality and recurrence rates is unclear. The aim of this study was to assess mortality after 18 months of follow-up. Furthermore, the incidence of recurrence and the risk factors for recurrence and death were evaluated (including the role played by anticoagulant and antiplatelet drugs). METHODS: Observational, prospective, multicentre, Italian study. RESULTS: 451/606 (74.4%) recruited patients with haemoptysis completed the 18 months follow-up. 22/604 (3.6%) diagnoses changed from baseline to the end of the follow-up. 83/604 (13.7%) patients died. In 52/83 (62.7%) patients, death was the outcome of the disease which caused haemoptysis at baseline. Only the diagnosis of lung neoplasm was associated with death (OR (95%CI): 38.2 (4.2-347.5); p-value: 0.0001). 166 recurrences were recorded in 103/604 (17%) patients. The diagnosis of bronchiectasis was significantly associated with the occurrence of a recurrence (OR (95% CI): 2.6 (1.5-4.3)); p-value < 0.0001). Anticoagulant, antiaggregant, and anticoagulant plus antiaggregant drugs were not associated with an increased risk of death and recurrence. CONCLUSIONS: Our study showed a low mortality rate in patients with haemoptysis followed-up for 18 months. Pulmonary malignancy was the main aetiology and the main predictor of death, whereas bronchiectasis was the most frequent diagnosis associated with recurrence. Antiplatelet and/or anticoagulant therapy did not change the risk of death or recurrence. Follow-up is recommended in patients initially diagnosed with lower airways infections and idiopathic bleeding. TRIAL REGISTRATION: NCT02045394.

Perioperative liberal versus restrictive fluid strategies and postoperative outcomes: a systematic review and metanalysis on randomised-controlled trials in major abdominal elective surgery.

BACKGROUND: Postoperative complications impact on early and long-term patients' outcome. Appropriate perioperative fluid management is pivotal in this context; however, the most effective perioperative fluid management is still unclear. The enhanced recovery after surgery pathways recommend a perioperative zero-balance, whereas recent findings suggest a more liberal approach could be beneficial. We conducted this trial to address the impact of restrictive vs. liberal fluid approaches on overall postoperative complications and mortality. METHODS: Systematic review and meta-analysis, including randomised controlled trials (RCTs). We performed a systematic literature search using MEDLINE (via Ovid), EMBASE (via Ovid) and the Cochrane Controlled Clinical trials register databases, published from 1 January 2000 to 31 December 2019. We included RCTs enrolling adult patients undergoing elective abdominal surgery and comparing the use of restrictive/liberal approaches enrolling at least 15 patients in each subgroup. Studies involving cardiac, non-elective surgery, paediatric or obstetric surgeries were excluded. RESULTS: After full-text examination, the metanalysis finally included 18 studies and 5567 patients randomised to restrictive (2786 patients; 50.0%) or liberal approaches (2780 patients; 50.0%). We found no difference in the occurrence of severe postoperative complications between restrictive and liberal subgroups [risk difference (95% CI) = 0.009 (- 0.02; 0.04); p value = 0.62; I2 (95% CI) = 38.6% (0-66.9%)]. This result was confirmed also in the subgroup of five studies having a low overall risk of bias. The liberal approach was associated with lower overall renal major events, as compared to the restrictive [risk difference (95% CI) = 0.06 (0.02-0.09); p value = 0.001]. We found no difference in either early (p value = 0.33) or late (p value = 0.22) postoperative mortality between restrictive and liberal subgroups CONCLUSIONS: In major abdominal elective surgery perioperative, the choice between liberal or restrictive approach did not affect overall major postoperative complications or mortality. In a subgroup analysis, a liberal as compared to a restrictive perioperative fluid policy was associated with lower overall complication renal major events, as compared to the restrictive.

Association between perioperative fluid administration and postoperative outcomes: a 20-year systematic review and a meta-analysis of randomized goal-directed trials in major visceral/noncardiac surgery.

BACKGROUND: Appropriate perioperative fluid management is of pivotal importance to reduce postoperative complications, which impact on early and long-term patient outcome. The so-called perioperative goal-directed therapy (GDT) approach aims at customizing perioperative fluid management on the individual patients' hemodynamic response. Whether or not the overall amount of perioperative volume infused in the context of GDT could influence postoperative surgical outcomes is unclear. METHODS: We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing the efficacy of GDT approach between study population and control group in reducing postoperative complications and perioperative mortality, using MEDLINE, EMBASE and the Cochrane Controlled Clinical trials register. The enrolled studies were grouped considering the amount infused intraoperatively and during the first 24 h after the admission in the critical care unit (perioperative fluid). RESULTS: The metanalysis included 21 RCTs enrolling 2729 patients with a median amount of perioperative fluid infusion of 4500 ml. In the studies reporting an overall amount below or above this threshold, the differences in postoperative complications were not statically significant between controls and GDT subgroup [43.4% vs. 34.2%, p value = 0.23 and 54.8% vs. 39.8%; p value = 0.09, respectively]. Overall, GDT reduced the overall rate of postoperative complications, as compared to controls [pooled risk difference (95% CI) = - 0.10 (- 0.14, - 0.07); Chi2 = 30.97; p value < 0.0001], but not to a reduction of perioperative mortality [pooled risk difference (95%CI) = - 0.016 (- 0.0334; 0.0014); p value = 0.07]. Considering the rate of organ-related postoperative events, GDT did not reduce neither renal (p value = 0.52) nor cardiovascular (p value = 0.86) or pulmonary (p value = 0.14) or neurological (p value = 0.44) or infective (p value = 0.12) complications. CONCLUSIONS: Irrespectively to the amount of perioperative fluid administered, GDT strategy reduces postoperative complications, but not perioperative mortality.

Medical thoracoscopy treatment for pleural infections: a systematic review and meta-analysis.

BACKGROUND: Complicated parapneumonic effusions and empyema represent advanced stages of pleural infections and are characterized by a high mortality. Medical thoracoscopy is a safe and minimally invasive endoscopic technique prescribed to treat severe pleural infections. However, only a few studies evaluated its success rate. A systematic review of observational studies was performed to assess the efficacy of medical thoracoscopy in patients with complicated parapneumonic effusions and empyema, as well as its predictive factors. METHODS: A search of the scientific evidence was carried out using PubMed, EMBASE, and Cochrane Central Register of Controlled Trials. Articles describing observational studies on medical thoracoscopy in patients with parapneumonic effusions and empyema were selected. RESULTS: Eight studies met the inclusion criteria. The pooled treatment success rate of thoracoscopy was 85% (95% CI 80.0-90.0%; I2: 61.8%) when used as first-line intervention or after failure of chest tube. The pooled complication rate was 9.0% (95% CI 6.0-14.0%; I2: 58.8%). A pooled difference of treatment success of 9.0% (95% CI 1.0-18.0%) was found when post-thoracoscopy intra-pleural fibrinolysis was prescribed. Pooled success rate was higher in cases with pleural fluid culture negativity (pooled difference: 14.0%; 95% CI 4.0-24.0%). CONCLUSIONS: Medical thoracoscopy is effective and safe when prescribed for complicated parapneumonic effusions and empyema. Bacteriological negativity of pleural effusion specimens and administration of adjuvant intra-pleural fibrinolysis after the procedure are associated with a higher success rate.
