Association of Vegetarian and Vegan Diets with Cardiovascular Health: An Umbrella Review of Meta-Analysis of Observational Studies and Randomized Trials.

BACKGROUND: Cardiovascular diseases (CVDs) are leading global causes of mortality. Unhealthy diets have been linked to an increased risk of CVD, while plant-based diets have shown potential protective effects. This umbrella review summarizes the evidence on the association between vegetarian diets and cardiovascular and cerebrovascular diseases. METHODS: PubMed, Scopus, Embase, CINAHL, Cochrane, and Web of Science were consulted. Meta-analyses grouped by author and outcome were performed. The heterogeneity was evaluated using I2 statistics. RESULTS: There was a 41.2% risk reduction for cerebrovascular disease. CVD incidence had a 29% reduced risk. CVD mortality had a 13.8% risk reduction, while IHD incidence had a 24.1% reduction, but with high heterogeneity. IHD mortality showed a significant 32.1% risk reduction. Ischemic stroke had a significant 32.9% risk reduction across six studies. Stroke incidence showed a significant 39.1% risk reduction in a single study. There was a non-significant 11.6% risk reduction for stroke mortality with moderate heterogeneity. CONCLUSION: Healthier diets are associated with reduced risks of cerebrovascular disease, CVD incidence, IHD mortality, and ischemic stroke. However, evidence quality and consistency vary, emphasizing the need for more research. Policymakers and healthcare professionals should prioritize promoting healthy diets for CVD prevention.

Meta-Analysis of Rates and Risk Factors for Local Recurrence in Surgically Resected Patients With NSCLC and Differences Between Asian and Non-Asian Populations.

Introduction: Postoperative radiotherapy (PORT) reduces local failure in patients with NSCLC, without a clear overall survival benefit. It is unknown whether the subsets of patients benefit. Two recent large randomized controlled trials, PORT-C (People's Republic of China) and Lung ART (Europe), reported widely different locoregional recurrence (LR) rates in the control arms, at 18.3% and 28.1% (46% of which were mediastinal recurrences), respectively. We performed a meta-analysis of patients with pathologic (p) N0 to N2 disease to evaluate the risk factors for LR and to explore possible differences in recurrence risk between Asian population (AP) and non-Asian population (NAP). Methods: We identified all original studies of curative NSCLC surgical resection which reported risk of LR between January 1, 2000, and January 10, 2021, excluding studies with less than 10 LR, patients with metastatic disease, or any neoadjuvant therapy. A total of 87 studies were identified with pN0 to N2 disease; of these, 56 were of high quality (HQ) on the basis of the Newcastle-Ottawa Scale. For each risk factor, we derived pooled relative risk (RR) and 5-year rate estimates using random-effects models. Results: Overall, the three significant highest pooled RRs (95% confidence intervals) for LR were pN2 versus pN0 (3.01, 1.39-6.55), lymphovascular invasion (1.92, 1.58-2.33), and advanced pT3-4 stage versus pT1 (1.86, 1.53-2.25). For HQ studies, the highest RRs for LR were lymphovascular invasion (1.94, 1.57-2.40), sublobar versus lobar resection (1.86, 1.46-2.36), and pN1 versus pN0 (1.84, 1.37-2.47), but pN2 versus pN0 was no longer significant (3.0, 0.57-15.61), on the basis of only two eligible studies. The RRs for LR were consistent for most factors in AP and NAP, although the RR for male versus female sex was higher in AP (1.44, 1.21-1.72) than in NAP (1.09, 0.99-1.19). Where reported, the pooled rate of LR at 5 years was lower in AP (12.0%) than in NAP (22.7%), despite similar overall 5-year recurrence rates (both LR and distal) in both populations: 38.0% in AP and 37.3% in NAP. Nevertheless, a lower 5-year mortality rate was noted in AP (24.3%) than in NAP (45.9%). Conclusions: There is little high-quality evidence to support the hypothesis that pN2 disease is a risk factor for LR, but LR seems to be lower in Asians. Prospective evaluation of LR factors and rates may be necessary before further prospective evaluation of PORT, because it may not depend on nodal status alone. Recurrence rates may differ in Asians. The impact of mutational status and modern treatment including targeted therapies and immune checkpoint inhibitors is inadequately studied.

Development and external validation of a predictive multivariable model for last-weeks survival of advanced cancer patients in the palliative home care setting (PACS).

PURPOSE: Various prognostic indexes have been proposed to improve physicians' ability to predict survival time in advanced cancer patients, admitted to palliative care (PC) with a survival probably to a few weeks of life, but no optimal score has been identified. The study aims therefore to develop and externally validate a new multivariable predictive model in this setting. METHODS: We developed a model to predict short-term overall survival in cancer patients on the basis of clinical factors collected at PC admission. The model was developed on 1020 cancer patients prospectively enrolled to home palliative care at VIDAS Milan, Italy, between May 2018 and February 2020 and followed-up to June 2020, and validated in two separate samples of 544 home care and 247 hospice patients. RESULTS: Among 68 clinical factors considered, five predictors were included in the predictive model, i.e., rattle, heart rate, anorexia, liver failure, and the Karnofsky performance status. Patient's survival probability at 5, 15, 30 and 45 days was estimated. The predictive model showed a good calibration and moderate discrimination (area under the receiver operating characteristic curve between 0.72 and 0.79) in the home care validation set, but model calibration was suboptimal in hospice patients. CONCLUSIONS: The new multivariable predictive model for palliative cancer patients' survival (PACS model) includes clinical parameters routinely at patient's admission to PC and can be easily used to facilitate immediate and appropriate short-term clinical decisions for PC cancer patients in the home setting.

Multidrug-Resistant Bacterial Colonization and Infections in Large Retrospective Cohort of Mechanically Ventilated COVID-19 Patients1.

Few data are available on incidence of multidrug-resistant organism (MDRO) colonization and infections in mechanically ventilated patients, particularly during the COVID-19 pandemic. We retrospectively evaluated all patients admitted to the COVID-19 intensive care unit (ICU) of Hub Hospital in Milan, Italy, during October 2020‒May 2021. Microbiologic surveillance was standardized with active screening at admission and weekly during ICU stay. Of 435 patients, 88 (20.2%) had MDROs isolated ≤48 h after admission. Of the remaining patients, MDRO colonization was diagnosed in 173 (51.2%), MDRO infections in 95 (28.1%), and non-MDRO infections in 212 (62.7%). Non-MDRO infections occurred earlier than MDRO infections (6 days vs. 10 days; p<0.001). Previous exposure to antimicrobial drugs within the ICU was higher in MDRO patients than in non-MDRO patients (116/197 [58.9%] vs. 18/140 [12.9%]; p<0.001). Our findings might serve as warnings for future respiratory viral pandemics and call for increased measures of antimicrobial stewardship and infection control.

Observed intervention effects for mortality in randomised clinical trials: a methodological study protocol.

INTRODUCTION: It is essential to choose a realistic anticipated intervention effect when calculating a sample size for a randomised clinical trial. Unfortunately, anticipated intervention effects are often inflated, when compared with the 'true' intervention effects. This is documented for mortality in critical care trials. A similar pattern might exist across different medical specialties. This study aims to estimate the range of observed intervention effects for all-cause mortality in trials included in Cochrane Reviews, within each Cochrane Review Group. METHODS AND ANALYSIS: We will include randomised clinical trials assessing all-cause mortality as an outcome. Trials will be identified from Cochrane Reviews published in the Cochrane Database of Systematic Reviews. Cochrane Reviews will be clustered according to the registered Cochrane Review Group (eg, Anaesthesia, Emergency and Critical Care) and the statistical analyses will be conducted for each Cochrane Review Group and overall. The median relative risk and IQR for all-cause mortality and the proportion of trials with a relative all-cause mortality risk within seven different ranges will be reported (relative risk below 0.70, 0.70-0.79, 0.80-0.89, 0.90-1.09, 1.10-1.19, 1.20-1.30 and above 1.30). Subgroup analyses will explore the effects of original design, sample size, risk of bias, disease, intervention type, follow-up length, participating centres, funding type, information size and outcome hierarchy. ETHICS AND DISSEMINATION: Since we will use summary data from trials already approved by relevant ethical committees, this study does not require ethical approval. Regardless of our findings, the results will be published in an international peer-reviewed journal.

Palliative medicine favourably influences end-of-life cancer care intensity: a large retrospective database study.

OBJECTIVES: Hospice and home palliative care have been associated to a reduction of aggressive treatments in the end-of-life, but data in the Italian context are scanty. Therefore, we aim to investigate the role of palliative care on indicators of end-of-life intensity of care among patients with cancer in Lombardy, the largest Italian region. METHODS: Within a retrospective study using the healthcare utilisation databases of Lombardy, Italy, we selected all residents who died in 2019 with a diagnosis of cancer. We considered as exposure variables admission to palliative care and time at palliative care admission, and as indicators of aggressive care hospitalisations, diagnostic/therapeutic procedures, in-hospital death, emergency department visits and chemotherapy over a time window of 30 days before death; chemotherapy in the last 14 days was also considered. RESULTS: Our cohort included 26 539 individuals; of these, 14 320 (54%) were admitted to palliative care before death. Individuals who were admitted to palliative care had an odds ratio (OR) of 0.27 for one hospitalisation, 0.14 for ≥2 hospitalisations, 0.25 for hospital stay ≥12 days, 0.38 for minor diagnostic/therapeutic procedures, 0.18 for major diagnostic/therapeutic procedures, 0.02 for in-hospital death, 0.35 for one emergency department visit, 0.29 for ≥2 emergency department visits and 0.66 for chemotherapy use in the last 30 days; the OR was 0.56 for chemotherapy use in the last 14 days. CONCLUSIONS: This large real-world analysis confirms and further support the importance of palliative care assistance for patients with cancer in the end- of- life; this is associated to a significant reduction in unnecessary treatments.

[Palliative Care in Lombardy Region: analysis of the care offer in 2019.] / Le cure palliative in Lombardia: analisi dell'offerta assistenziale nel 2019.

OBJECTIVE: The Lombardy Region has one of the most widespread and advanced models of Palliative Care (PC) in the country. However, there is a relative lack of updated data referring to the activity of the Lombardy PC network. METHODS: This work aims to describe the activity carried out in the two main PC care settings (home care and hospice) in 2019 through the analysis of the data sent by each Unit to the Lombardy Region. Data were analysed on a regional basis and considering the 8 Health Protection Agencies (ATS) separately. RESULTS: In 2019, PC activity was provided by 114 home care units (1.14/100,000 inhabitants) and 70 hospice for a total of 812 beds (8.1 beds/100,000 inhabitants). Overall, 25,514 patients were assisted for a total of 29,892 care pathway. 77.6% of the patients assisted were oncologic and about 67% of the patients who died of cancer in Lombardy were intercepted by CP. 54.4% of patients were taken care of in home care, although with a significant difference between cancer patients (58%) and non-cancer patients (42%). In home care, average activation time was 2.8 days and in 81% of cases the assistance was activated within 24-48 hours; in hospice, average activation time was 3.5 days, with 60% of admissions within 24 hours and over 30% with waiting time ≥3 days. The median duration of home palliative care was approximately 21 days (average 40.5), that in hospice was 9 days (average 17.2). In the home care pathways, the prevalent outcome was the death of the patient at home (64%) and hospitalization in hospice (17.2%), while 86% of hospitalizations in hospice ended with death. CONCLUSIONS: This accurate report of the Lombardy PC activity indicates that PC satisfy various qualitative indicators of structural and care process identified by national regulations. However, PC still remain predominantly intended for cancer patients, with relatively short duration of care, particularly in the hospice setting.
