Cardiovascular risk and access to primary care: Comparisons among Chinese documented and undocumented immigrants.

AIMS: The aim of this study was to examine main risk factors of undocumented Chinese migrants living in Italy when compared with Chinese migrants registered with National Health Service (NHS). METHODS: A cohort of 3435 Chinese first-generation immigrants living in Prato underwent blood pressure (BP) measurement and blood tests. Hypertension was diagnosed for BP ≥ 140/90 mmHg at 2 visits, and/or antihypertensive drug use; type 2 diabetes (T2DM) for fasting glucose ≥ 126 mg/dL at 2 visits, and/or use of hypoglycemic drugs; hypercholesterolemia (HC) for cholesterol ≥ 240 mg/dL and/or statins use. Subjects diagnosed with hypertension, T2DM, or HC unaware of their condition were considered newly diagnosed. Comparisons were performed using multivariable adjusted logistic regression analysis. RESULTS: A large proportion of Chinese migrants were undocumented (1766, 51 %); newly diagnoses of risk factors were performed especially among undocumented migrants; registration with NHS was associated with higher level of awareness for hypertension and T2DM and with 6 times higher rate of treatment for T2DM. Only a small minority of subjects with high cholesterol were treated with statins. CONCLUSIONS: Undocumented immigrants had high prevalence of risk factors with lower levels of awareness than migrants registered with the NHS. Health policies targeting this hard-to-reach population needs to be improved.

Flurbiprofen in the subglottic space to prevent postoperative sore throat after cardiac surgery: A randomized double-blind study.

STUDY OBJECTIVE: Postoperative sore throat (POST) and hoarseness are common complications of tracheal intubation. This study aims to evaluate the efficacy of flurbiprofen administered through the subglottic port of tracheal tubes to prevent POST after cardiac surgery. DESIGN: Single-center, prospective, randomized, double-blind, placebo-controlled trial. SETTING: Tertiary Care Referral University Hospital (Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome). PATIENTS: Included 71 patients undergoing for elective cardiac surgery. Inclusion criteria were (a) age between 50 and 75 years, (b) NYHA class I or II, (c) surgery for myocardial revascularization or valve repair or replacement under cardiopulmonary bypass. INTERVENTION: Patients were double blind randomized to receive flurbiprofen or saline in the subglottic port of the endotracheal tube (groups F and P). The solution was injected ten minutes after tracheal tube placement, ten minutes after ICU admission and ten minutes before tracheal tube removal. MEASUREMENTS: The primary outcome was to assess the effect of topical flurbiprofen administered through the subglottic port of the tracheal tube to prevent post-operative sore throat (POST). The secondary outcomes were the presence of hoarseness safety and patient's subjective satisfaction with their recovery. We did not report any exploratory outcomes. MAIN RESULTS: We analyzed 68 patients, 34 patients in each group. In group F, two patients complained of POST and hoarseness (5.9%), while all controls did. The two groups significantly differed in the severity scores (VAS and TPS for sore throat and HOAR for hoarseness) at all time points. In group P, patients reported mild to moderate symptoms that significantly improved or disappeared 36 h after tracheal tube removal. According to the multivariable model, hoarseness affected women less than men, in the control group (p = 0.002). None of the patients in either group reported any adverse effects. CONCLUSIONS: Repeated administration of flurbiprofen through the subglottic port of tracheal tubes reduced the incidence of sore throat and hoarseness after cardiac surgery without evidence of complications.

Comparison of De-Kay repair versus De Vega suture for functional tricuspid regurgitation: a preliminary experience.

BACKGROUND: In patients undergoing mitral valve surgery, restrictive suture annuloplasty (De Vega) for less-than-severe functional tricuspid regurgitation has been proven to be safe and effective. The aim of this study is to determine whether the adjunct of the plication of the posterior tricuspid leaflet with the same running suture (bicuspidized De Vega or "De Kay") is equally safe and effective. METHODS: Single center, retrospective study on patients submitted to suture repair of the tricuspid valve during mitral valve surgery, with either conventional or De Kay, between January 2014 and December 2020. Comparison was based on degree of residual tricuspid valve regurgitation and right ventricular assessment at discharge. RESULTS: Over the course of the study period, 255 patients undergoing mitral valve surgery had a dilated (>40 mm or >20 mm/m2) tricuspid valve annulus, with less-than-severe tricuspid regurgitation. Conventional De Vega was employed in 166 patients (65.1%) and De Kay in the remaining 89 (34.9%). At discharge the adjunct of postero-septal commissure plication has similar outcomes to the classic De Vega repair. It seems to preserve right ventricular function. CONCLUSIONS: De Kay repair guarantees the same tricuspidal regurgitation reduction as compared with conventional De Vega early after surgery.

Complications associated with the use of peripherally inserted central catheters and midline catheters in COVID-19 patients: An observational prospective study.

BACKGROUND: Among the many interesting aspects of clinical care during the SARS-CoV-2 pandemic, vascular access still deserves some attention. Peripherally inserted central catheters (PICCs) and midline catheters (MCs) are venous access devices inserted by ultrasound-guided puncture of veins of the arm, which have been associated with the possibility of minimizing infectious complications in different populations of patients. We have investigated their performance in SARS-CoV-2 patients. METHODS: As the incidence of catheter-related bloodstream infections (CRBSI) in patients hospitalized for COVID-19 is still unclear, we have designed a single-center, prospective observational study enrolling all patients with established diagnosis of SARS-CoV-2 infection who were admitted to our hospital in the period between October 2020 and April 2021 and who required either a PICC or a MC. RESULTS: We recruited 227 patients. The cumulative incidence of CRBSI was 4.35% (10 cases), that is, 3.5 episodes/1,000 catheter days. Four CRBSI occurred in patients with PICCs (4.5/1,000 catheter days) and 6 in those with MCs (3.2/1,000 catheter days). CONCLUSIONS: Our data suggest that COVID-19 patients may have a more pronounced tendency for the development of catheter-related infections compared to other populations of patients.

Two innovative aortic bioprostheses evaluated in the real-world setting. First results from a two-center study.

BACKGROUND: The increasing use of biological substitutes for surgical aortic valve replacement (AVR), has led to the development of new bioprostheses with improved hemodynamics and expected durability. METHODS: In this observational retrospective two-center cohort study, two innovative bioprostheses, INSPIRIS Resilia and AVALUS were analyzed. We analyzed early and 2.4-year follow-up results in terms of safety, clinical outcome and hemodynamic performance. RESULTS: From November 2017 to February 2021, 148 patients underwent AVR with INSPIRIS Resilia (N.=74) or AVALUS (N.=74) bioprosthesis. The 30-day and mid-term mortality was comparable (1% vs. 3%, P=0.1 and 7% vs. 4%, P=0.4, respectively). Valve-related mortality was observed in one AVALUS patient. Three (4%) patients of the AVALUS group developed prosthetic endocarditis and two of them died after reoperation. No other cases of prosthetic endocarditis were observed. No cases of structural valve degeneration or significant paravalvular leak were detected at follow-up. Median follow-up peak pressure gradient was 21 vs. 23 mmHg (P=0.4) and the mean pressure gradient was 12 vs. 13 mmHg (P=0.9) for Inspiris and AVALUS, respectively. The effective orifice area (EOA) and indexed EOA were 1.5 cm2 vs. 1.4 cm2 (P=0.4) and 0.8 vs. 0.7 cm2/m2 (P=0.5), respectively. Indexed left ventricular mass regression was -33 vs. -52 g/m2 for the Inspiris and AVALUS groups, respectively, (R2-adjusted =0.14; P<0.01). CONCLUSIONS: INSPIRIS Resilia and AVALUS bioprostheses were reliable with comparable results in safety, clinical outcome and hemodynamic performance. After statistical adjustment, AVALUS was associated with better left ventricular mass reduction. Long-term follow-up would provide definitive comparative results.

Single shot of intravenous iron in cardiac surgery: The ICARUS study.

BACKGROUND: Iron deficiency (ID), with or without anemia, is commonly observed among patients scheduled for cardiac surgery. We investigated if screening ID in the immediate preoperative period and treating ID patients regardless of anemia could reduce perioperative transfusion requirements. METHODS: This is an observational single-center propensity score-matched study including candidates to elective cardiac surgery prospectively and retrospectively enrolled. Prospectively enrolled patients were screened for ID at hospital admission: if ferritin was ≤100 µg/L or ≤ 300 µg/L with transferrin saturation index ≤20% they received intravenous ferric carboxymaltose, B12-vitamin, and folic acid. A retrospective series of patients not screened for ID and matched for gender, type of surgery, BMI, Goudie transfusion risk score, hemoglobin level, and red blood cell (RBC) indices, served as controls. The primary outcome was the proportion of patients requiring ≤1 packed RBC (pRBC) unit within day 7 or discharge The main secondary outcomes were intraoperative and postoperative pRBC transfusions, duration of hospitalization, and cost-effectiveness of ID screening and treatment. RESULTS: We included 479 prospective and 833 retrospective cases: 442 patients screened for ID and 442 matched controls with unknown iron status were analyzed. ID was observed in 196 patients (44.3%) and iron was administered 1 day (IQR 1-2) before surgery. Overall, 76.9% of patients in the prospective group and 69.7% of controls received ≤1 pRBC transfusion (p = 0.014). The risk for multiple transfusions was lower in patients screened for ID (OR 0.689, 95% CI 0.510-0.930). Despite similar Hb levels at day 7, patients in the prospective group received fewer postoperative pRBC transfusions (p < 0.001) and had a shorter hospital length of stay (p < 0.001). Globally, hospitalization costs were lower in patients screened and treated for ID. CONCLUSIONS: Short-term pre-operative iron therapy is associated with a reduction in postoperative transfusions in anemic and non-anemic ID cardiac surgery patients and has a favorable impact on hospitalization costs. CLINICAL TRIAL REGISTRATION: NCT04744181.

Performance, clinical outcomes and implementation of an original heart valve clinic model.

BACKGROUND: Valvular heart disease (VHD) requires optimized outpatient management that is generally considered to be best delivered by a dedicated, multidisciplinary team (Heart Valve Clinic [HVC]). Although HVC is promoted by clinical guidelines and organized in many centers, real world outcome assessments are limited. Thus, we evaluated the performance, clinical and management outcomes during a 6-year experience with an original HVC model. METHODS: By interrogating the local database, 1047 consecutive patients admitted to the HVC from January 2015 to October 2020 were found. Management and mortality were checked for all patients. After 3 years of HVC activity, in order to improve appropriateness and efficiency, access priority criteria were introduced. Thus, the study population was divided in two period subgroups (before and after access criteria introduction) that were compared. RESULTS: A total of 1047 consecutive patients admitted to the HVC constituted the study population; 346 patients (33%) were recommended for invasive treatment. After a mean follow-up of 25.7±3.1 months, 37 patients (3.5%) died. When comparing study periods, statistically significant increase inpatients' complexity and VHD severity was noticed in Period 2, also translating into higher rate of referral to intervention (39.0% vs. 29.4% in Period 1; P=0.001). Finally, despite higher rate of elderly and frail patients, operative mortality was not jeopardized. CONCLUSIONS: The present study reports a comprehensive assessment of the characteristics and outcomes achieved through an original HVC model. Standardization of access criteria supports the HVC improvement.

Description of a Sarcoptic Mange Outbreak in Alpine Chamois Using an Enhanced Surveillance Approach.

Since 1995, the Alpine chamois (Rupicapra r. rupicapra) population of the Dolomites has been affected by sarcoptic mange with considerable management concerns. In this study, 15 years (2006-2020) of passive surveillance and demographic data were analyzed in order to describe a mange outbreak. Furthermore, an enhanced passive surveillance protocol was implemented in order to evaluate the efficiency of ordinary vs. enhanced surveillance protocol in identifying dead chamois in the field and in reaching a correct diagnosis. Our results confirm the role of mange as a determining factor for chamois mortality, while stressing the importance of a wider view on the factors affecting population dynamics. The enhanced passive surveillance protocol increased the probability of carcass retrieval and identification of the cause of death; however, its adoption may be too costly if applied for long periods on a wide scale. Passive surveillance, in both ordinary and enhanced surveillance protocol, should encompass the use of other strategies in the future to study the eco-epidemiology of the disease in wild Caprinae.

Postoperative Intensive Care Management of Aortic Repair.

Vascular surgery patients have multiple comorbidities and are at high risk for perioperative complications. Aortic repair surgery has greatly evolved in recent years, with an increasing predominance of endovascular techniques (EVAR). The incidence of cardiac complications is significantly reduced with endovascular repair, but high-risk patients require postoperative ST-segment monitoring. Open aortic repair may portend a prohibitive risk of respiratory complications that could be a contraindication for surgery. This risk is greatly reduced in the case of an endovascular approach, and general anesthesia should be avoided whenever possible in the case of endovascular repair. Preoperative renal function and postoperative kidney injury are powerful determinants of short- and long-term outcome, so that preoperative risk stratification and secondary prevention are critical tasks. Intraoperative renal protection with selective renal and distal aortic perfusion is essential during open repair. EVAR has lower rates of postoperative renal failure compared to open repair, with approximately half the risk for acute kidney injury (AKI) and one-third of the risk of hemodialysis requirement. Spinal cord ischemia used to be the most distinctive and feared complication of aortic repair. The risk has significantly decreased since the beginning of aortic surgery, with advances in surgical technique and spinal protection protocols, and is lower with endovascular repair. Endovascular repair avoids extensive aortic dissection and aortic cross-clamping and is generally associated with reduced blood loss and less coagulopathy. The intensive care physician must be aware that aortic repair surgery has an impact on every organ system, and the importance of early recognition of organ failure cannot be overemphasized.

Myocardial fibrosis in asymptomatic patients undergoing surgery for mitral and aortic valve regurgitation.

BACKGROUND: Chronic heart valve regurgitation induces left ventricular (LV) volume overload, leading to the development of hypertrophy and progressive dilatation of the ventricle to maintain physiological cardiac output. In order to prevent potential irreversible LV structural changes, the identification of the best timing for treatment is pivotal. OBJECTIVE: To assess the presence and extent of fibrosis in myocardial tissue in asymptomatic patients with valvular heart disease (VHD) and preserved LV dimensions and function undergoing cardiac surgery. METHODS: Thirty-nine patients were enrolled. Sixteen patients were affected by aortic or mitral regurgitation: they were all asymptomatic, undergoing valve surgery according to VHD European Society of Cardiology guidelines. Twenty-three patients with end-stage nonischemic dilated cardiomyopathy (DCM) and severe LV dysfunction undergoing cardiac surgery for implantation of a durable left ventricular assist device (LVAD) served as controls. During surgery, VHD patients underwent three myocardial biopsies at the level of the septum, the lateral wall and LV apex, while in LVAD patients the coring of the apex of the LV was used. For both groups, the tissue samples were analyzed on one section corresponding to the apical area. All slides were stained with hematoxylin and eosin and Masson's trichrome staining and further digitalized. The degree of fibrosis was then calculated as a percentage of the total area. RESULTS: Of 39 patients, 23 met the inclusion criteria: 12 had mitral or aortic insufficiency with a preserved ejection fraction and 11 had idiopathic dilated cardiomyopathy. Quantitative analysis of apical sections revealed a myocardial fibrosis amount of 10 ±â€Š6% in VHD patients, while in LVAD patients the mean apical myocardial fibrosis rate was 38 ±â€Š9%. In VHD patients, fibrosis was also present in the lateral wall (9 ±â€Š4%) and in the septum (9 ±â€Š6%). CONCLUSION: Our case series study highlights the presence of tissue remodeling with fibrosis in asymptomatic patients with VHD and preserved LV function. According to our results, myocardial fibrosis is present at an early stage of the disease, well before developing detectable LV dysfunction and symptoms. Since the relationship between the progressive magnitude of myocardial fibrosis and potential prognostic implications are not yet defined, further studies on this topic are warranted.

Non-invasive follicular neoplasm with papillary-like nuclear features: a challenging and infrequent entity in Argentina.

PURPOSE: Non-invasive encapsulated follicular variant of papillary thyroid cancer was reclassified as non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). These neoplasms have an extremely low malignant potential. The aim of this study was (1) to assess the prevalence of NIFTP in patients with papillary thyroid carcinoma, (2) to evaluate their outcomes, and (3) to determine their molecular profile. METHODS: Multicenter, descriptive, retrospective study. Patients with papillary thyroid cancer diagnosed from January 2006 to December 2016 from 11 referral centers were included. Diagnosis of NIFTP was based on criteria described by Nikiforov et al. in 2018. At least two pathologists agreed on the diagnosis. Two thousand six hundred and seventy-seven papillary thyroid cancer patients were included; 456 (17%) of them were follicular variant papillary thyroid cancer, and 30 (1.12%) fulfilled diagnostic criteria for NIFTP. RESULTS: Each of the 30 included patients underwent a total thyroidectomy, and 50% were treated with radioiodine (median dose 100 mCi). After a median follow-up of 37 months, 84% of patients had an excellent response, 3% had an indeterminate response and data was missing in the remaining 13%. No metastatic lymph nodes, distant metastases or recurrences were found. RAS mutations were detected in 4 patients (13%). CONCLUSION: The prevalence of NIFTP in our series is amongst the lowest reported. Excellent outcomes of patients underscore their low malignant potential. Molecular findings differ from other series, probably related to environmental or ethnic features of our population and the meticulous criteria for diagnosing NIFTP.

Body-Size Perception among First-Generation Chinese Migrants in Italy.

Body-size perception is an important factor in motivating people to lose weight. Study aim was to explore the perception of body image among first-generation Chinese migrants living in Italy. A sample of 1258 Chinese first-generation immigrants and of 285 native Italians living in Prato, Italy, underwent blood pressure measurements, blood tests (with measurement of glucose, cholesterol, and triglycerides), and anthropometric measurements. Body-size perception was investigated with Pulvers' figure rating scale using logistic or linear multivariable regression adjusted for age, gender, BMI, education and years spent in Italy. Chinese migrants had lower BMI and discrepancy score (preferred minus current body size) than Italians (p < 0.05 for both). After a logistic regression analysis, the discrepancy score remained lower in the Chinese than in the Italian cohort independently from BMI and other confounders (OR 0.68; 95%CI 0.50 to 0.92). In the Chinese cohort, female gender, BMI and years spent in Italy were positive determinants of discrepancy score (desire to be thinner), while age showed negative impact (p < 0.05 for all). Overweight is an important risk factor for diabetes, a very prevalent condition among first-generation Chinese migrants. The present study offers useful information and suggests the need for prevention programs specifically addressed to men.

Bleeding Complications in Patients With Perioperative COVID-19 Infection Undergoing Cardiac Surgery: A Single-Center Matched Case-Control Study.

OBJECTIVE: Previous studies reported a poor outcome in patients with coronavirus 2019 (COVID-19) undergoing cardiac surgery. Complications most frequently described were respiratory failure, renal failure, and thromboembolic events. In their recent experience, the authors observed a very high incidence of bleeding complications. The purpose of the study was to investigate a possible significant correlation between perioperative COVID-19 infection and hemorrhagic complications compared to non-COVID-19 patients. DESIGN: Single-center, observational, retrospective, matched case-control (1:2) study involving patients who underwent open-heart cardiac surgery from February 2020 and March 2021 with positive perioperative diagnosis of COVID-19 infection, matched with patients without COVID-19 infection. SETTING: Cardiac surgery unit and intensive care unit of a university tertiary center in a metropolitan area. PARTICIPANTS: In the study period, 773 patients underwent cardiac surgery on cardiopulmonary bypass (CPB). Among them, 23 consecutive patients had perioperative diagnosis of COVID-19 infection (study group). These patients were compared with 46 corresponding controls (control group) that matched for age, sex, body mass index, and Society of Thoracic Surgeons score. INTERVENTIONS: Open-heart cardiac surgery on CPB. MEASUREMENTS AND MAIN RESULTS: In the study group, 2 patients (9%) died in the intensive care unit from severe respiratory failure, shock, and multiple organ failure. In the study group, patients showed a significantly higher incidence of bleeding complications (48% v 2%, p = 0.0001) and cases of surgical reexploration for bleeding (35% v 2%, p = 0.0001), a higher incidence of severe postoperative thrombocytopenia (39% v 6%, p = 0.0007), and a higher need of blood components transfusions (74% v 30%, p = 0.0006). Chest tubes blood loss and surgical hemostasis time were markedly prolonged (p = 0.02 and p = 0.003, respectively). CONCLUSIONS: A worrisome increased risk of early and late bleeding complications in COVID-19 patients was observed, and it should be considered when assessing the operative risk. CPB-related inflammatory reaction could exacerbate the deleterious effect of COVID-19 on the coagulation system and likely deviate it toward a hemorrhagic pattern.

Molecular surveillance of pneumococcal carriage following completion of immunization with the 13-valent pneumococcal conjugate vaccine administered in a 3 + 1 schedule.

In a cross-sectional study, with the use of molecular methods, we aimed to gain insight into oropharyngeal pneumococcal colonization over time in 1212 Greek children recruited in general pediatric settings throughout the country; they were fully vaccinated with PCV13 (3 + 1 schedule). A single sample was obtained from each child at a time interval of 26 days to 70 months after administration of the 4th (booster) PCV13 dose; sampling time was divided into six time intervals. Carriage of Streptococcus pneumoniae was detected by real-time PCR targeting the lytA gene and isolates were serotyped by singleplex real-time PCR assays. Multiple control procedures to avoid false-positive results were applied. We showed an overall S. pneumoniae carriage rate of 48.6%. Serotyping identified typeable isolates in 82% of the total lytA-positive samples. Non-PCV13 serotypes represented 83.8% of total isolates when excluding serogroups with mixed PCV13 and non-PCV13 serotypes. In multivariate analysis daycare/school attendance emerged as the main contributing factor. Notably, serotypes 19A and 3 were the only two PCV13 serotypes the colonization rate of which increased over time (χ2 for trend P < 0.001 and P = 0.012, respectively). The application of the SP2020 gene on lytA-positive serotyped samples showed pneumococcal colonization in 97% of cases, and the overall colonization profile over time closely resembled that of the lytA gene. With the provisions of the methodological approach and age group of our study, the use of the oropharynx emerges as a reliable alternative to the nasopharynx in estimating pneumococcal carriage in epidemiological studies.

Gender differences in acculturation and cardiovascular disease risk-factor changes among Chinese immigrants in Italy: Evidence from a large population-based cohort.

BACKGROUND: In recent decades, the Chinese presence in Southern Europe has grown rapidly but no data is available on the influence that residing in Mediterranean countries has on Chinese immigrants. In this study, we aim to examine the association between acculturation and cardiovascular risk factors among first-generation Chinese immigrants in Italy. DESIGN: Population-based, cross-sectional study. METHODS: A sample of 2589 Chinese first-generation immigrants (1599 women and 990 men) living in Prato, Italy, underwent blood pressure measurement, blood tests (with measurement of glucose, cholesterol, and triglycerides), and anthropometric measurements. The influence of length of residence (dependent variable) on hypertension, type 2 diabetes, overweight/obesity, and hyperlipidemia (high cholesterol) (independent variables) was investigated with multivariable logistic regression adjusted for age, sex, education and urban/rural home area in China before migration. RESULTS: Mean age of Chinese participants was 47.2 ± 10.7 years and 61.7% were women. Immigrants residing in Italy for ≥20 years were more likely to be hypertensive [odd ratio (OR) 1.84; 95% confidence interval (CI) 1.33 to 2.59], or diabetic (1.91; 1.26 to 2.86) than those residing in Italy for <10 years. Differently, prevalence of hypercholesterolemia (total cholesterol≥240 mg/dl) was lower in immigrants residing in Italy for ≥20 years than in those with <10 years of residence (0.52; 0.32 to 0.83). The association between indicators of acculturation and cardiovascular risk factors appeared to differ by sex. CONCLUSION: Acculturation of Chinese immigrants in Italy was associated with hypertension and type 2 diabetes whereas a favorable effect on hypercholesterolemia was observed.

Influence of cardiopulmonary bypass set-up and management on clinical outcomes after minimally invasive aortic valve surgery.

INTRODUCTION: Minimally invasive aortic valve replacement (MIAVR) requires changes in cannulation strategy and cardiopulmonary bypass (CPB) management when compared to the conventional approach (CAVR). We aimed at evaluating if these differences could influence perfusion-related quality parameters and impair postoperative outcomes. METHODS: Overall, 339 consecutive patients underwent MIAVR or CAVR between 2014 and 2020 and were analyzed retrospectively. To account for baseline differences, a propensity-matching analysis was performed, obtaining two groups of 97 patients each. RESULTS: MIAVR group had longer CPB time [107 (95-120) vs 95 (86-105) min, p = .003] than CAVR group. Of note, average pump flow rate index [2.4 (2.2-2.5) vs 2.7 (2.4-2.8) l/min/m2, p = .004] was lower in the MIAVR group. Mean arterial pressure was 73 = 9 mmHg vs 62 = 11 mmHg for the MIAVR and CAVR group, respectively (p < .001). Cell-salvaged blood was most commonly used in the MIAVR group (25.8% vs 11.3%, p = .02). Finally, CPB temperature was 32.8°C (32.1-34.8) for MIAVR group vs 34.9°C (33.2-36.1) for the CAVR group (p = .02). Postoperative complications were similar between groups. CONCLUSIONS: In conclusion, despite differences in CPB parameters in patients undergoing CAVR and MIAVR, the incidences of adverse outcomes were similar. However, compared to CAVR, MIAVR was associated with shorter durations of mechanical ventilation and hospital stay as well as less transfusion of blood products.

Gait analysis may distinguish progressive supranuclear palsy and Parkinson disease since the earliest stages.

Progressive supranuclear palsy (PSP) is a rare and rapidly progressing atypical parkinsonism. Albeit existing clinical criteria for PSP have good specificity and sensitivity, there is a need for biomarkers able to capture early objective disease-specific abnormalities. This study aimed to identify gait patterns specifically associated with early PSP. The study population comprised 104 consecutively enrolled participants (83 PD and 21 PSP patients). Gait was investigated using a gait analysis system during normal gait and a cognitive dual task. Univariate statistical analysis and binary logistic regression were used to compare all PD patients and all PSP patients, as well as newly diagnosed PD and early PSP patients. Gait pattern was poorer in PSP patients than in PD patients, even from early stages. PSP patients exhibited reduced velocity and increased measures of dynamic instability when compared to PD patients. Application of predictive models to gait data revealed that PD gait pattern was typified by increased cadence and longer cycle length, whereas a longer stance phase characterized PSP patients in both mid and early disease stages. The present study demonstrates that quantitative gait evaluation clearly distinguishes PSP patients from PD patients since the earliest stages of disease. First, this might candidate gait analysis as a reliable biomarker in both clinical and research setting. Furthermore, our results may offer speculative clues for conceiving early disease-specific rehabilitation strategies.

Long-term results of tricuspid annuloplasty with 3-dimensional-shaped rings: effective and durable!

OBJECTIVES: 3-Dimensional (3D)-shaped rings are largely adopted for tricuspid annuloplasty, but evidence about their long-term results is scanty. The goal of this study was to analyse the long-term results of tricuspid annuloplasty with 3D-shaped rings. MATERIALS AND METHODS: A retrospective review of our prospectively maintained database was carried out to identify all patients who underwent tricuspid valve repair with 3D-shaped rings between January 2011 and December 2014. Kaplan-Meier methods were used to analyse long-term survival. Cumulative incidence function using death as the competitive outcome was used to estimate cardiac death. RESULTS: A total of 168 patients were identified. The median age was 66 years. Eighty-two patients (49%) were in advanced New York Heart Association functional class III-IV. Atrial fibrillation (AF) was present in 101 (60%); the median ejection fraction was 60%. In 82 (49%) patients, a Medtronic 3D Contour annuloplasty ring was employed; in the remaining 86 (51%) patients, an Edwards MC3 ring was used. Cumulative incidence function of cardiac death, with non-cardiac death as a competing risk, was 1.9 ± 1.1%, 95% confidence interval (CI) (0.51-4.95) at 7 years. The cumulative incidence function of recurrence of tricuspid regurgitation (TR) ≥2+ at 7 years was 14 ± 3.17%, 95% CI (8.49-20.82). Recurrence of TR ≥2+ at 7 years was not significantly different between the Medtronic 3D Contour and the Edwards MC3 rings (P = 0.3). AF was identified as the only independent predictor of recurrence of TR ≥2+. CONCLUSIONS: 3D-shaped rings are effective and durable. TR recurrence was relatively low at 7 years and usually moderate (2+/4+) without a significant difference between the 2 types of rings. The role of AF as a predictor of TR recurrence was confirmed.
