The clinical impact of pectoral nerve block in an 'enhanced recovery after surgery' program in breast surgery.

Background: Pectoral nerve block (PECS) is increasingly performed in breast surgery. Aim: The study evaluated the clinical impact of these blocks in the postoperative course. Patients & methods: In this case-control study, patients undergoing breast surgery with 'enhanced recovery after surgery' pathways were divided into group 1 (57 patients) in whom PECS was performed before general anesthesia, and group 2 (57 patients) in whom only general anesthesia was effected. Results: Postoperative opioid consumption (p < 0.002), pain at 32 h after surgery (p < 0.005) and the length of stay (p < 0.003) were significantly lower in group 1. Conclusion: Reducing opioid consumption and pain after surgery, PECS could favor a faster recovery with a reduction in length of stay, ensuring a higher turnover of patients undergoing breast surgery.

'Enhanced recovery after surgery' (ERAS) protocols have been recently applied in breast cancer patients in order to improve the postoperative course. However, the incidence of moderate to severe pain after breast surgery is frequent, and a multimodal approach is recommended. In this view, the interfascial plane blocks are advocated as a valid alternative to both paravertebral and epidural blockade. In this study, we evaluated the effects of these blocks on the postoperative course in patients undergoing breast surgery with ERAS protocols. We compared two patient groups: in the first, pectoral blocks were performed before general anesthesia, while in the second no block was carried out. We found that in the patient group receiving the blocks, postoperative opioid consumption (with essentially the same pain after surgery) and length of stay were significantly lower. Therefore, although more robust studies are needed to confirm our findings, these emerging locoregional techniques could favor a faster recovery in the context of ERAS in breast surgery. These results could have important clinical implications in terms of not only reducing healthcare costs but also ensuring a higher turnover of patients undergoing breast surgery.

The multidisciplinary audit in enhanced recovery after surgery (ERAS) colorectal surgery: experience in a single Italian center.

BACKGROUND: Current literature underlines the role of periodical feed-back to improve Enhanced Recovery After Surgery (ERAS) path adherence during implementation program. The aim of this retrospective study was to evaluate the clinical impact of an audit program in an ERAS path. METHODS: All elective patients submitted to elective colorectal surgery from November 2018 to January 2020 in our Institution were considered. The sample was divided into two study groups: group 1, including patients enrolled in the first sixth months of ERAS program until the first audit; group 2, patients enrolled in a time period of a six months after the first audit. RESULTS: The final analysis included 46 patients in group 1 and 64 in group 2. Group 2 showed a higher ASA Score (P<0.03), a higher prevalence of right hemicolectomy, and a lower prevalence of left hemicolectomy and anterior rectum resection (RAR) (P<0.016). Group 2 also had a lower prevalence of anastomotic leakage (AL) (P<0.004). Intraoperative normothermia (T>36 C°) in this group was achieved in a larger number of patients in comparison with group 1 (39% vs. 19.5%) (P<0.01). Group 2 experienced a higher average body temperature at admission in recovery room (RR) when compared to Group 1 (35.8 vs. 35.1 C°, P<0.01). CONCLUSIONS: Audit program may represent a useful tool to promote advantageous changes in clinical practice and to favor a better compliance to ERAS program.

The Role of the Recovery Room in Improving Adherence During an Enhanced Recovery After Surgery (ERAS) Implementation Program for Colorectal Surgery: A Single-Center Retrospective Analysis.

PURPOSE: The purpose of thisstudy was to evaluate the clinical impact of the Recovery Room (RR) in an Enhanced Recovery After Surgery (ERAS) pathway in colorectal surgery. DESIGN: Single-center retrospective study. METHODS: From November 2019 until September 2021, a total of 149 consecutive patients that underwent to colon-rectal surgery were enrolled. The patients were divided into two study groups: RR Group if admitted to RR after surgery, and no-Recovery Room (NRR) Group if monitored directly on the ward, bypassing the RR. The postoperative ERAS items adherence was assessed in the two study groups. FINDINGS: Final analysis included 119 patients in the RR Group and 30 patients in NRR Group. Patients that started clear liquid oral intake within two hours postoperatively were 118 in the RR group and 19 in the NRR group (99.1% vs 63.3%, P < .001). A total of 98 patients and 18 patients were mobilized on day 0 in the RR group and in NRR group, respectively (84.4% vs 15.5%, P < .05). In the RR group, postoperative adherence to the ERAS protocol components was higher in comparison with the NRR group (P < .003); adherence to the all protocol components was also higher (P < .004). CONCLUSIONS: Among patients undergoing colorectal surgery admitted to RR after surgery, the RR nurse guaranteed effective patient assistance and ensured appropriate compliance to the postoperative ERAS items.

"In Less than No Time": Feasibility of Rotational Thromboelastometry to Detect Anticoagulant Drugs Activity and to Guide Reversal Therapy.

Anticoagulant drugs (i.e., unfractionated heparin, low-molecular-weight heparins, vitamin K antagonists, and direct oral anticoagulants) are widely employed in preventing and treating venous thromboembolism (VTE), in preventing arterial thromboembolism in nonvalvular atrial fibrillation (NVAF), and in treating acute coronary diseases early. In certain situations, such as bleeding, urgent invasive procedures, and surgical settings, the evaluation of anticoagulant levels and the monitoring of reversal therapy appear essential. Standard coagulation tests (i.e., activated partial thromboplastin time (aPTT) and prothrombin time (PT)) can be normal, and the turnaround time can be long. While the role of viscoelastic hemostatic assays (VHAs), such as rotational thromboelastometry (ROTEM), has successfully increased over the years in the management of bleeding and thrombotic complications, its usefulness in detecting anticoagulants and their reversal still appears unclear.

Improved diastolic dysfunction is associated with higher forward flow and better prognosis in chronic heart failure.

The benefit of repeat assessment of left ventricular (LV) systolic and diastolic function in heart failure (HF) remains uncertain. We assessed the prognostic value of repeat echocardiographic assessment of LV filling pressure (LVFP) and its interaction with cardiac index (CI) in ambulatory patients with chronic HF and reduced ejection fraction (HFrEF). We enrolled 357 patients (age 68 ± 11 years; 22% female) with chronic HFrEF. Patients underwent a clinical and echocardiographic examination at baseline. LVFP as assessed by the 2016 Guidelines and Doppler-derived CI were estimated. After the second echocardiographic examination, patients were followed for a median time of 30 months. The study endpoint included all-cause death and hospitalization for worsening HF. Patients who normalized LVFP or showed persistently normal LVFP at the follow-up examination had a significantly lower mortality rate than those with worsening or persistently raised LVFP (p < 0.0001). After stratification by CI, patients with elevated LVFP and CI < 2.0 l/min/m2 had a further worse outcome than those with elevated LVFP and CI ≥ 2.0 l/min/m2 (p < 0.0001). Multivariate survival analysis confirmed an independent prognostic impact of changes in LVFP, incremental to that of established clinical, laboratory and echocardiographic predictors. Repeat assessment of LVFP and CI significantly improved risk stratification of chronic HFrEF outpatients compared to baseline evaluation.

Ferric carboxymaltose vs. ferrous sulfate for the treatment of anemia in advanced chronic kidney disease: an observational retrospective study and cost analysis.

In non-dialysis-dependent chronic kidney disease (NDD-CKD), erythropoiesis-stimulating agents (ESAs) and iron supplementation are essential for anemia management. Ferric carboxymaltose (FCM) is a relatively novel intravenous iron formulation used in different clinical settings, although scarce data exist in NDD-CKD patients. Primary objective of this study was to retrospectively evaluate the efficacy of FCM compared with oral ferrous sulfate for the treatment of iron-deficiency anemia in a cohort of NDD-CKD patients, considering also the treatment costs. This was a monocentric, retrospective observational study reviewing 349 NDD-CKD patients attending an outpatient clinic between June 2013 and December 2016. Patients were treated by either FCM intravenous infusion or oral ferrous sulfate. We collected serum values of hemoglobin, ferritin and transferrin saturation (TSAT) and ESAs doses at 12 and 18 months. The costs related to both treatments were also analysed. 239 patients were treated with FCM intravenous infusion and 110 patients with oral ferrous sulfate. The two groups were not statistically different for age, BMI and eGFR values. At 18 months, hemoglobin, serum ferritin and TSAT values increased significantly from baseline in the FCM group, compared with the ferrous sulfate group. ESAs dose and rate of infusion decreased only in the FCM group. At 18 months, the treatment costs, analysed per week, was higher in the ferrous sulfate group, compared with the FCM group, and this was mostly due to a reduction in ESAs prescription in the FCM group. Routine intravenous FCM treatment in an outpatient clinic of NDD-CKD patients results in better correction of iron-deficiency anemia when compared to ferrous sulfate. In addition to this, treating NDD-CKD patients with FCM leads to a significant reduction of the treatment costs by reducing ESAs use.

Discrepancies in Assessing Diastolic Function in Pre-Clinical Heart Failure Using Different Algorithms-A Primary Care Study.

BACKGROUND: Current guidelines on diastolic function (DF) by the American Society of Echocardiography and the European Association of Cardiovascular Imaging (ASE/EACVI) have been disputed and two alternative algorithms have been proposed by Johansen et al. and Oh et al. We sought (a) to assess the concordance of ASE/EACVI guidelines on DF using these proposed alternative approaches and (b) to evaluate the prevalence of indeterminate diastolic dysfunction (DD) by each method, exploring means for reducing their number. METHODS: We retrospectively analyzed the echocardiographic reports of 1158 outpatients including subjects at risk of heart failure without (n = 644) or with (n = 241) structural heart disease, and 273 healthy individuals. Concordance was calculated using the k coefficient and overall proportion of DD reclassification rate. The effectiveness of pulmonary vein flow (PVF), Valsalva maneuver, and left atrial volume index/late diastolic a'-ratio (LAVi/a') over indeterminate grading was assessed. RESULTS: The DD reclassification rate was 30.1% (k = 0.35) for ASE/EACVI and OH, 36.5% (k = 0.27) for ASE/EACVI and JOHANSEN and 31.1% (k = 0.37) for OH and JOHANSEN (p < 0.0001 for all comparisons). DF could not be graded only by ASE/EACVI and OH in 9% and 11% patients, respectively. The majority of patients could be reclassified using PVF or Valsalva maneuver or LAVi/a', with the latter being the single most effective parameter. CONCLUSION: Inconsistencies between updated guidelines and independent approaches to assess and grade DF impede their interchangeable clinical use. The inconclusive diagnoses can be reconciled by conventional echocardiography in most patients, and LAVi/a' emerges as a simple and effective approach to this aim.

Very early postoperative troponin increase and clinical outcome in patients admitted to the recovery room after noncardiac surgery with suspected cardiac events.

We assessed the prognostic meaning of very early (<6 h) troponin increase after noncardiac surgery in a population of patients admitted to the recovery room, for whom troponin measurements were taken because of a suspected cardiac event. Among a total of 296 patients, abnormal troponin was found in 24 (8.1%). Ten patients in this group (41.7%) and 27 among those with normal troponin (9.9%) experienced cardiovascular death, myocardial infarction, or decompensated heart failure at one month (p < 0.0001). Troponin was independently associated with a two-fold risk of events (p < 0.0001). In these patients, very early troponin measurement in the recovery room may help to identify patients at risk of cardiovascular events.

Tissue Doppler indices of diastolic function as prognosticator in patients without heart failure in primary care.

BACKGROUND: Tissue Doppler imaging (TDI) indices of left ventricular (LV) diastolic function provide incremental prognostic information on mortality and morbidity in the general population and in several clinical scenarios. Their independent, additional role in outpatients with normal LV ejection fraction (LVEF) and without heart failure (HF) is undefined. METHODS: We reviewed clinical and echocardiographic records of 2628 consecutive outpatients 52.8% male, median age 71 years) with LVEF > 50% without concurrent or prior HF, from the Cardiovascular Center of Trieste. We analyzed septal early mitral annular velocity (e') and its combination with mitral peak early filling velocity (E/e') in relation to the composite end-point of death and cardiovascular hospitalizations. RESULTS: During follow-up of 26 months (interquartile range: 12-41), 392 (15%) patients experienced the endpoint (88 deaths). Increasing E/e' showed an overall association with the clinical end-point (log rank p < 0.02), but with no prognostic difference between the middle and upper tertile. Decreasing e' also showed an association with the end-point, with a more balanced stepwise risk increase for increasing tertiles (log rank p < 0.01 for all contrasts). At multivariable analysis, E/e' (either in tertiles or dichotomized according to the threshold of 15) was no longer associated with clinical outcome, whereas e' independently predicted the combined endpoint [hazard ratio 0.73 (0.53-0.94), p = 0.04]. The prognostic value of e' was incremental to that of other clinical and echocardiographic variables (p = 0.04). CONCLUSIONS: In outpatients with normal LVEF and without HF, e' and E/e' are both associated with clinical end-points, though only e' is an independent and incremental predictor of outcome. These findings suggest a potential role for e' as a prognosticator, and spread a cautionary word about the utilization of septal E/e' alone as a surrogate for a comprehensive assessment of diastolic function in this context.

[Chronic diseases and risk of symptomatic COVID-19: results of a case-population study on a sample of patients in the Local Health Unit 'Toscana Centro' (Tuscany Region, Central Italy)]. / Malattie croniche e rischio di ammalarsi di COVID-19 sintomatica: risultati di uno studio case-population su un campione di casi in AUSL Toscana Centro.

BACKGROUND: the COVID-19 pandemic represents a challenge for health systems around the world, with just under 10,000 cases in Tuscany Region (Central Italy) and about 4,500 in the Local Health Unit (LHU) 'Toscana Centro', updated on 11 May 2020. The risk factors reported are several, including age, being male, and some chronic diseases such as hypertension, diabetes, respiratory and cardiovascular diseases. However, the relative importance of chronic diseases is still to be explored. OBJECTIVES: to evaluate the role of chronic diseases on the risk to develop clinically evident (at least mild symptomatic) forms of SARS-CoV-2 infection in the population of the LHU Toscana Centro. DESIGN: case-population study. SETTING AND PARTICIPANTS: 'case' is a subject with SARS-CoV-2 positive swab with at least mild clinical status, who lives in the LHU Toscana Centro area; 'controls' are all people residing in the LHU Toscana Centro area at 1 January 2020. People aged under 30 and patients living in nursing care homes are excluded from the analysis. MAIN OUTCOME MEASURES: the analysis assesses the effect of gender, age, neoplasm, and the main chronic diseases on the onset of an infection with at least mild symptoms by calculating odds ratios (OR) by multivariate logistic regression models (to produce adjusted OR by potential confounders). RESULTS: among the 1,840 cases, compared to the general population, the presence of males and over-60-year-old people is greater. Almost all the considered chronic diseases are more frequent among the cases, compared to the general population. A chronic patient has a 68% greater risk to be positive with at least mild symptoms. Many of the considered diseases show an effect on the risk of getting COVID-19 in a symptomatic form, which remains even adjusting by other comorbidities. The main ones include heart failure, psychiatric disorders, Parkinson's disease, and rheumatic diseases. CONCLUSIONS: these results confirm evidence already shown in other studies on COVID-19 patients and add information on the chronic diseases attributable risk in the population, referred to the symptomatic forms and adjusted by age, gender or the possible copresence of more diseases. These risk estimates should guide prevention interventions by health services in order to protect the chronic patients affected by the pathologies most at risk.

Chronic Care Model for the Management of Patients with Heart Failure in Primary Care.

We recently investigated the prognostic impact of a Chronic Care Model (CCM)-based healthcare program applied in primary care in Tuscany Region mainly run by multidisciplinary teams composed of general practitioners (GPs) and nurses. The project included proactively planned follow-up visits for each patient, individualized counselling to optimize lifestyle modifications and adherence to appropriate diagnostic and therapeutic pathways. 1761 patients with Chronic heart failure (CHF) directly enrolled by the GPs were matched with 3522 CHF controls not involved in the project. Over a 4-year follow-up in the CCM group a higher CHF hospitalization rate was found (12.1 vs 10.3 events/100 patient-years; incidence rate ratio [IRR] 1.15, p=0.0030), whereas mortality was lower (10.8 vs 12.6 events/100 patient-years; IRR 0.82, p<0.0001). The CCM status was independently associated with a 34% increase in the risk of CHF hospitalization and a 18% reduction in the risk of death (p<0.0001 for both). The CCM status was associated with a 50% increase in the rate of planned Heart failure (HF) hospitalizations whereas the rate of 1-month CHF readmissions showed no differences. Such a divergent trend could be explained by the direct involvement of GPs in the CCM program, leading them to a better awareness of patients' clinical status, and then to a more frequent use of clinical pathways and facilities, including hospitalization. It is reasonable to argue that not all hospitalizations must necessarily be considered as a poor outcome, as they often provide additional opportunities to improve therapies, optimize patient education, or define follow-up strategies. The evidence of a divergent trend between mortality and hospitalization in our population might support the clinical importance of a multidisciplinary approach for the management of patients with HF.

Blood flow maintenance by cardiac massage during cardiopulmonary resuscitation: Classical theories, newer hypotheses, and clinical utility of mechanical devices.

The mechanisms by which closed chest cardiac massage produces and maintains blood flow during cardiopulmonary resuscitation are still debated. To date, two main theories exist: the "cardiac pump", which assumes that blood flow is driven by direct cardiac compression and the "chest pump", which hypothesizes that blood flow is caused by changes in intrathoracic pressure. Newer hypotheses including the "atrial pump", the "lung pump", and the "respiratory pump" were also proposed. We reviewed studies supporting these different theories as well as the clinical evidences on the utility of mechanical devices proposed to optimize cardiopulmonary resuscitation, in view of their pathophysiological assumptions with regard to the underlying theory. On the basis of current evidence, a single theory is probably not sufficient to explain how cardiac massage produces blood flow. This suggests that different simultaneous mechanism might be involved. The relative importance of these mechanisms depends on several factors, including delay from collapse to starting of resuscitation, compression force and rate, body habitus, airway pressure, and presenting electrocardiogram. The complexity of the physiologic events occurring during cardiopulmonary resuscitation, together with the need of adequate training for a correct and prompt utilization of mechanical devices, might also partially explain the disappointing results of these devices in most clinical studies.

Speckle tracking echocardiography and right ventricle dysfunction in acute respiratory distress syndrome a pilot study.

PURPOSE: Speckle tracking echocardiography is a novel echocardiographic technique to assess RV myocardial function but no data are so far available in patients with acute respiratory distress syndrome (ARDS), and we aimed at assessing the feasibility of 2 dimensional (2D) speckle tracking echocardiography and the prognostic role of RV free wall speckle tracking strain in 30 consecutive patients with moderate-severe ARDS MATERIALS AND METHODS: In an observational prospective study, 30 consecutive patients with moderate-severe ARDS were enrolled. Echocardiography was performed within 12 hours from ICU admission. RESULTS: Mortality rate was 33% (10/30). Non-survivors showed lower values of pH (7.32 ± 0.09, P = 0.03) and higher troponin I levels (0.32 (0.08-0.46), P = 0.04), NT-pro BNP (3091 (2662-7128), P = 0.009), and SAPS II (60.3 ± 9.6, P < 0.001). At echocardiographic examination, non-survivors showed lower values of TAPSE (18.3 ± 3, P = 0.034) and higher systolic pulmonary arterial pressure (49.6 ± 16, P = 0.05). Two patients (6.6%) did not show valid acoustic windows. Only three patients showed normal values of RV strain free wall (22%, 25%, and 28% absolute values, respectively), among whom one patient died. When compared to survivors, non-survivors showed significantly lower values of RV strain free wall (-10.4 ± 0.10, P < 0.001). CONCLUSIONS: In mechanically ventilated moderate-severe ARDS, 2D speckle tracking is feasible even though difficult acoustic windows are common. Further studies are needed to confirm our findings in a larger cohort of patients.

Giant isolated intracardiac thrombus presenting as acute heart failure secondary to right ventricular outflow tract obstruction in a patient with renal carcinoma.

Right-sided intracardiac thrombi are potential causes of right ventricular (RV) failure, particularly when tricuspid or pulmonary obstruction occurs. In most cases, RV thrombus develops in patients with RV dysfunction and concomitant thrombosis in the systemic veins. However, RV thrombosis can rarely present as an isolated mass and despite preserved RV function, particularly in patients with thrombophilic states. In this report, we describe an unusual case of giant isolated RV thrombus presenting with acute RV failure secondary to dynamic RV outflow tract obstruction in a patient with renal carcinoma. Bedside echocardiography allowed a rapid assessment of the hemodynamic effects of the mass. The possibility of a thrombotic RV outflow obstruction should be considered in patients with acute RV failure, even in those with no evidence of thrombosis in the venous district. This may be particularly important in patients with prothrombotic states, where the effectiveness of routine thromboembolic prophylaxis could be reduced.

Clinical Utility of a Structured Program to Reduce the Risk of Health-Related Quality of Life Impairment after Discharge from Intensive Care Unit: A Real-World Experience.

BACKGROUND: Postdischarge deterioration in health-related quality of life (HRQoL) is a major clinical issue for patients after an intensive care unit (ICU) hospitalization. A significant proportion of these patients is known to develop a progressive worsening of mental and physical performance-the so-called post-intensive care syndrome (PICS). AIM: We aimed at exploring the effects of a structured program for the management of ICU patients, aimed at improving postdischarge HRQoL and reducing the risk of PICS. METHODS: A total of 159 patients hospitalized in our ICU with a length of stay >72 hours were enrolled in an institutional management protocol including specific recommendations: adequate sedation and analgesia protocols, to ensure a valid delirium prevention strategy, and to provide a planned midterm after discharge. The main endpoint was the occurrence of PICS at the 6-month follow-up visitation, defined as an abnormal physical or mental score in the SF-12 questionnaire in the presence of clinical evidence of new or worsening impairment in physical, cognitive, or mental health status. An additional questionnaire was administered, to assess the effects of ICU-related memories. RESULTS: Most patients positively rated their health at the 6-month follow-up and had no significant impairment in physical or mental health status. The mean normalized values of the physical and mental component of the SF-12 score were 46 ± 11 and 48 ± 14, suggesting a normal physical and mental health status in most patients. Twenty-nine patients (18.2%) showed evidence of PICS. Similar good results were found by the questionnaire of memories. In multivariable analysis, no variable was found to predict the risk of PICS in our population. CONCLUSION: In this real-world analysis that lacks a control group, patients who used a program aimed at minimizing the risk of HRQoL deterioration and PICS reported a good perception of their state of health with a relatively low prevalence of PICS.

Opposite trends in hospitalization and mortality after implementation of a chronic care model-based regional program for the management of patients with heart failure in primary care.

BACKGROUND: The chronic care model (CCM) is an established framework for the management of patients with chronic illness at the individual and population level. Its application has been previously shown to improve clinical outcome in several conditions, but the prognostic impact of CCM-based programs for the management of patients with chronic heart failure (HF) in primary care is still to be elucidated. METHODS: We assessed the prognostic impact of a primary-care, CCM-based project applied in Tuscany, Italy, in 1761 patients with chronic HF enrolled in a retrospective matched cohort study. The project was based on predefined working teams including general practitioners and nurses, proactively scheduled regular follow-up visitations for each patient, counseling for therapy adherence and lifestyle modifications, appropriate diagnostic and therapeutic pathways according to international guidelines, and a key supporting role of the nurses, who were responsible for the practical coordination of the follow-up. A matched group of 3522 HF subjects assisted by general practitioners not involved in the project was considered as control group. The endpoints of this study were HF hospitalization and all-cause mortality. RESULTS: Over a 4-year follow-up period, HF hospitalization rate was higher in the CCM group than the controls (12.1 vs 10.3 events/100 patient-years; incidence rate ratio 1.15[1.05-1.27], p = 0.0030). Mortality was lower in the CCM group than the controls (10.8 vs 12.6 events/100 patient-years; incidence rate ratio 0.82[0.75-0.91], p < 0.0001). In multivariable analysis, the CCM status was associated with a 34% higher risk of HF hospitalization and 18% lower risk of death (p < 0.0001 for both). The effect on HF hospitalization was mostly driven by a 50% higher rate of planned HF hospitalization. CONCLUSIONS: Implementation of a CCM-based program for the management of HF patients in primary care led to reduced mortality and increased HF hospitalization. These findings support the hypothesis that the beneficial effects of CCM on survival might be extended to patients with chronic HF followed in primary care, but also support the need for further strategies aimed at improving the management of these patients in terms of hospitalizations.
