The Impact

<p><strong>Background:</strong> We evaluated the results of different types of cardiovascular surgery in patients with chronic renal failure (CRF) (serum creatinine ?2 mg/dL) who were not dialysis-dependent.</p><p><strong>Methods:</strong> Eighty-two patients who presented with non-dialysis-dependent CRF were retrospectively evaluated. Patients in Group 1 (n = 12) underwent valvular surgery, those in Group 2 (n = 58) underwent coronary artery bypass grafting (CABG), and those in Group 3 (n = 12) underwent combined CABG and valvular surgery.</p><p><strong>Results:</strong> The demographics were similar among the groups. Cardiopulmonary bypass and aortic cross-clamping times were shorter (<em>P</em> &lt; .01), the use of blood and blood products was less, and the mechanical ventilation time and hospital stay were shorter in Group 2 in comparison to the other groups (<em>P</em> &lt; .01). There were 4 (6.9%) early mortalities in Group 2. Late mortalities occurred in 4 (33.3%), 16 (27.6%), and 6 (50%) patients from Groups 1, 2, and 3, respectively. Cox regression analysis revealed that age, the presence of a preoperative cerebrovascular accident, the presence of a left main coronary lesion, preoperative blood urea nitrogen level, and the use of blood and blood products were independent risk factors for early mortality. High Euroscore, cerebrovascular accident, the use of platelet suspension, longer ventilation support times, and combined CABG and valvular surgery were independent risk factors for late mortality.</p><p><strong>Conclusions:</strong> Morbidity and survival seemed to be more dependent on preoperative patient characteristics than the type of surgery in this group of patients. Combined CABG and valvular surgery was a risk factor for late mortality.</p>

Background and Aim: Immunoglobulin A nephropathy (IgAN) is the most common primary glomerulopathy. The Oxford classification was recently updated to include crescents as markers of poor prognosis. The aim of this study was to evaluate the impact of cellular crescents on the prognosis of patients with IgAN in Brazil. Methods: This was a single-centre retrospective analysis of medical records and renal biopsies in patients with IgAN. The renal biopsy findings were classified according to the revised Oxford classification: mesangial hypercellularity, endocapillary hypercellularity (E), segmental glomerulosclerosis (S), tubular atrophy or interstitial fibrosis (T), and crescent formation (C). We evaluated a composite outcome (progression to end-stage renal disease or creatinine doubling). We performed analyses between the patients with crescents in the renal biopsy specimen (C1/C2 group) and those without such crescents (C0 group). Results: We evaluated 111 patients, of whom 72 (65.0%) were women, 80 (72.0%) self-identified as White, 73 (65.6%) were hypertensive, and 95 (85.6%) had haematuria. The distribution of patients according to cellular crescentic lesions was: C0, 80 (72%); C1, 27 (24.4%); C2, 4 (3.6%). The composite outcome was observed in 33 (29.72%) of the 111 patients. In comparison with the C0 group, the C1/C2 group had higher proportions of patients with hypertension (p = 0.04), haematuria (p = 0.03), worse serum creatinine (p = 0.0007), and worse estimated glomerular filtration rate (p = 0.0007). The C1/C2 group also had higher proportions of patients in whom the biopsy specimen was classified as E1 (p = 0.009), S1 (p = 0.001), or T1/T2 (p = 0.03), In addition, the mean follow-up period was shorter in the C1/C2 group (p < 0.0001). Furthermore, the composite outcome was observed in a greater proportion of patients and in a shorter length of time in the C1/C2 group than in the C0 group (p = 0.002 and p = 0.0014, respectively). In a Cox regression analysis, the independent risk factors for the composite outcome had Oxford classifications of S1, T1/T2, and C1/C2. Conclusion: Oxford classification findings of S1, T1/T2, or C1/C2 were independent risk factors for the composite outcome, corroborating previous studies.

Background: The aim of our study was to develop a nomogram model to predict overall survival (OS) and cancer-specific survival (CSS) in patients with gastric signet ring cell carcinoma (GSRC). Methods: GSRC patients from 2004 to 2015 were collected from the Surveillance, Epidemiology, and End Results (SEER) database and randomly assigned to the training and validation sets. Multivariate Cox regression analyses screened for OS and CSS independent risk factors and nomograms were constructed. Results: A total of 7,149 eligible GSRC patients were identified, including 4,766 in the training set and 2,383 in the validation set. Multivariate Cox regression analysis showed that gender, marital status, race, AJCC stage, TNM stage, surgery and chemotherapy were independent risk factors for both OS and CSS. Based on the results of the multivariate Cox regression analysis, prognostic nomograms were constructed for OS and CSS. In the training set, the C-index was 0.754 (95% CI = 0.746-0.762) for the OS nomogram and 0.762 (95% CI: 0.753-0.771) for the CSS nomogram. In the internal validation, the C-index for the OS nomogram was 0.758 (95% CI: 0.746-0.770), while the C-index for the CSS nomogram was 0.762 (95% CI: 0.749-0.775). Compared with TNM stage and SEER stage, the nomogram had better predictive ability. In addition, the calibration curves also showed good consistency between the predicted and actual 3-year and 5-year OS and CSS. Conclusion: The nomogram can effectively predict OS and CSS in patients with GSRC, which may help clinicians to personalize prognostic assessments and clinical decisions.

Objectives: We analyzed risk factors for mortality in febrile neutropenic patients with bloodstream infections (BSI) presenting with septic shock and assessed the impact of empirical antibiotic regimens. Methods: Multicenter retrospective study (2010-2019) of two prospective cohorts comparing BSI episodes in patients with or without septic shock. Multivariate analysis was performed to identify independent risk factors for mortality in episodes with septic shock. Results: Of 1563 patients with BSI, 257 (16%) presented with septic shock. Those patients with septic shock had higher mortality than those without septic shock (55% vs 15%, p<0.001). Gram-negative bacilli caused 81% of episodes with septic shock; gram-positive cocci, 22%; and Candida species 5%. Inappropriate empirical antibiotic treatment (IEAT) was administered in 17.5% of septic shock episodes. Empirical β-lactam combined with other active antibiotics was associated with the lowest mortality observed. When amikacin was the only active antibiotic, mortality was 90%. Addition of empirical specific gram-positive coverage had no impact on mortality. Mortality was higher when IEAT was administered (76% vs 51%, p=0.002). Age >70 years (OR 2.3, 95% CI 1.2-4.7), IEAT for Candida spp. or gram-negative bacilli (OR 3.8, 1.3-11.1), acute kidney injury (OR 2.6, 1.4-4.9) and amikacin as the only active antibiotic (OR 15.2, 1.7-134.5) were independent risk factors for mortality, while combination of β-lactam and amikacin was protective (OR 0.32, 0.18-0.57). Conclusions: Septic shock in febrile neutropenic patients with BSI is associated with extremely high mortality, especially when IEAT is administered. Combination therapy including an active β-lactam and amikacin results in the best outcomes.

Abstract Background Predictors and clinical outcomes of VF-ACC and the relative VF-ACC incidence with various access routes have not been well documented. This study aimed to identify predictors, clinical outcomes, and relative incidences of ventricular fibrillation after the release of an aortic cross-clamp (VF-ACC) with various access routes in valvular surgery.Patients and methods In this single-center and retrospective cohort study, we screened 228 consecutive patients undergoing valve surgery, and a total of 119 patients were included in the study. The primary outcomes were the relative incidence and predictors of VF-ACC with access routes, and secondary endpoints included effects of VF-ACC on 30-day mortality, perioperative ventricular arrhythmias (VAs), and heart failure with ejection fraction < 50% (HFEF < 50%).Results VF-ACC incidence varied on the basis of access routes. VF-ACC occurred in 58.3% of patients with aortic valve replacement via transverse aortotomy (TAo-AVR), in 48.6% of patients with aortic and mitral replacements via transseptal and transverse aortotomy access (TSAo-MAVR), and in 20% of patients with mitral valve replacement via transseptal access (TS-MVR). Seven independent risk factors were identified: HTK solution (AOR: 4.90, p = 0.002), smoking status (AOR: 6.30, p = 0.001), cerebrovascular disease (CBD) [(AOR: 7.08, p = 0.022)], regional wall motion abnormality (RWMA) [(AOR: 8.33, p < 0.001)], perioperative VAs (AOR: 4.85, p = 0.001), HFEF < 50% (AOR: 5.66, p = 0.002), and left ventricular mass index (LVMI) [(AOR: 0.962, CI: 0.941–0.984)].Conclusions VF-ACC was the most common in TAo-AVR and the least common in TS-MVR. HTK solution, smoking status, CBD, perioperative VAs, HFEF < 50%, and RWMA were associated with an increased risk of VF-ACC, and low LVMI acted as a protective factor. Patients with VF-ACC commonly experienced perioperative VAs or HFEFs < 50%.Clinical trial registration: ChiCTR2100050961.

And Oxidative Stress

Ascending aorta aneurysm (AsAA) is a complex disease, currently defined an inflammatory disease. In the sporadic form, AsAA has, indeed, a complex physiopathology with a strong inflammatory basis, significantly modulated by genetic variants in innate/inflammatory genes, acting as independent risk factors and as largely evidenced in our recent studies performed during the last 10 years. Based on these premises, here, we want to revise the impact of reactive oxygen species (ROS) and oxidative stress on AsAA pathophysiology and consequently on the onset and progression of sporadic AsAA. This might consent to add other important pieces in the intricate puzzle of the pathophysiology of this disease with the translational aim to identify biomarkers and targets to apply in the complex management of AsAA, by facilitating the AsAA diagnosis currently based only on imaging evaluations, and the treatment exclusively founded on surgery approaches.

Observation Period

The majority of patients with myelodysplastic syndromes (MDS) require regular red blood cell (RBC) transfusions. Alloimmunization (AI) against blood products is an adverse event, causing time-consuming RBC compatibility testing. The reported incidence of AI in MDS patients varies greatly. Even though different studies on AI in MDS patients have been performed, there are still knowledge gaps. Current literature has not yet fully identified the risk factors and dynamics of AI in individual patients, nor has the influence of disease modifying treatment (DMT) been explored. Therefore, we performed this study to evaluate the effect of DMT on AI. An observational, population-based study, using the HemoBase registry, was performed including all newly diagnosed MDS patients between 2005 and 2017 in Friesland, a province of the Netherlands. All available information about treatment and transfusions, including transfusion dates, types, and treatment regimens, was collected from the electronic health records and laboratory systems. Follow-up occurred through March 2019. For our patient cohort, blood products were matched for AB0 and RhD, and transfused per the 'type and screen' policy (i.e. electronic matching of blood group phenotype between patient and donor). After a positive antibody screening, antibody identification and Rh/K phenotyping was performed and subsequent blood products were (cross)matched accordingly. The observation period was counted from first transfusion until last transfusion or first AI event. Univariate analyses and cumulative frequency distributions were performed to study possible risk factors and dynamics of AI. DMT was defined as hypomethylating agents, lenalidomide, chemotherapy and monoclonal antibodies. The effect of DMT as a temporary risk period on the risk of AI was estimated with incidence rates, relative risks (RR) and hazard ratios (HR) using a cox regression analysis. Follow-up was limited to 24 months for the cox regression analysis to avoid possible bias by survival differences. Statistical analyses were performed using IBM SPSS 24 and SAS 9.4. Out of 292 MDS patients, 236 patients received transfusions and were included in this study, covering 463 years of follow-up. AI occurred in 24 patients (10%). AI occurred mostly in the beginning of the observation period: Eighteen patients (75%) were alloimmunized after receiving 20 units of RBCs, whereas 22 patients (92%) showed AI after 45 units of RBCs (Figure 1). We found no significant risk factors for AI in MDS patients at baseline. DMT was given to 67 patients (28%) during the observation period. Patients on DMT received more RBC transfusions than patients that did not receive DMT (median of 33 (range: 3-154) and 11 (range: 0-322) RBC units respectively, p<0,001). Four AI events (6%) occurred in patients on DMT and 20 AI events (12%) occurred in patients not on DMT. Cox regression analysis of the first 24 months of follow-up showed an HR of 0.30 (95% CI: 0.07-1.31; p=0.11). The incidence rates per 100 person-years were 3.19 and 5.92 respectively. The corresponding RR was 0.54 (95% CI: 0.16-1.48; p=0.26). Based on our results, we conclude that the incidence of AI in an unselected, real world MDS population receiving RBC transfusions is 10% and predominantly occurred in the beginning of follow-up. Risk factors for AI at baseline could not be identified. Our data showed that patients on DMT received significantly more RBC transfusions but were less susceptible to AI. Therefore, extensive matching of blood products may not be necessary for patients on DMT. Larger studies are needed to confirm the protective effect of DMT on AI.

Abstract Background: The objective of this study was to assess the impact of the recurrent laryngeal nerve injury (RLNI) after esophagectomy on prognosis.Methods: Retrospectively collected data from 297 patients with esophageal squamous cell carcinoma who underwent McKeown esophagectomy at our department from April 2014 to May 2018, were analyzed.Results: RLNI occurred in 31.9% of the patients. Left-side RLNI occurred 2.8 times more often than right-side RLNI. Among the cases in which assessment of the vocal cords was continued, 8.4% involved permanent injury. There were no significant differences among clinicopathological data between patients with RLNI and without. Compared with patients without RLNI,patients with RNLI have longer operation time,more number of bronchoscopy suctions, longer postoperation hospital stay, and higher incidence of postoperative complications. T stage, N stage, RLN LN metastasis were independent risk factors for the prognosis, but RLNI is not independent risk factors for long-term survival. Conclusion: RLNI is a serious complication that will affect the short-term prognosis of patients and reduce the quality of life of patients. It should be avoided as much as possible during surgery, but it may not have negative impact on the long-term survival.

Objective To analyze the prevalence of urinary incontinence (UI) in female patients with an indication for bariatric surgery, to investigate the potential risk factors and the impact on quality of life. Methods A cross-sectional study with female patients with obesity. The evaluation consisted of a structured interview, a specific study form and quality of life questionnaires. The Poisson regression was performed to identify independent risk factors related to UI. Results A total of 221 patients were enrolled; 118 of the study participants (53.4%) reported UI episodes. Mixed UI (MUI), stress UI (SUI) only, and urgency UI (UUI) only were reported by 52.5% (62), 33.9% (40) , and 13.5% (16) of these patients respectively. The prevalence of UI was increased by 47% among the women who had given birth vaginally and by 34% of the women who had entered menopause. Vaginal delivery and menopause were identified as independent risk factors related to UI. The mean International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) score was 9.36 ± 4.9. The severity of symptoms was considered moderate in 53.3% (63) of the patients with UI. Conclusion Urinary incontinence impacts quality of life negatively, and the prevalence of UI is high among obese patients. In the present study, vaginal delivery and menopause were independently associated with UI.

Abstract OBJECTIVES The association of unstable heart disease and resectable lung cancer is rare. The impacts of staged management, cardiac surgery with cardiopulmonary bypass (CPB) versus angioplasty, on long-term survival and cancer recurrence remain debated. We report our experience using staged management. METHODS From 1997 to 2016, 107 patients were treated at the Quebec Heart and Lung Institute: 72 underwent cardiac surgery with CPB (group 1), 35 were treated with angioplasty (group 2), followed by oncological pulmonary resection. RESULTS Two postoperative deaths (3%) and 1 ischaemic heart complication (1%) were reported in group 1. One death (3%) was reported in group 2. Two-year overall survival was 82% (59/72) in group 1 and 80% (28/35) in group 2; 5-year overall survival was 62% (33/53) in group 1 and 63% (19/30) in group 2. Two-year disease-free survival in group 1 was 79% (57/72) and 77% (27/35) in group 2; 5-year disease-free survival was 58% (31/53) in group 1 and 60% (18/30) in group 2. The independent risk factors for death after thoracic surgery were transfusions (P = 0.004) and grade ≥3 complications (P = 0.034). Independent risk factors for recurrence included the cancer stage (P &lt; 0.001) and, paradoxically, a shorter delay between cardiac and lung procedures (P = 0.031). CONCLUSIONS When a staged management remains feasible after cardiac procedure, oncological outcomes of patients with cardiopathy and lung cancer are satisfactory. CPB does not seem to be deleterious. The delay between procedures should intuitively be as small as possible but not at the expense of good recovery after the cardiac procedure.

Abstract INTRODUCTION We retrospectively analyzed the impact on post-relapse survival of selected prognostic factors and salvage therapy (finalized to perform an allo-SCT) in 145 patients (pts) with non-APL AML who had been initially treated with standard induction and risk-adapted consolidation. The aim was to identify factors associated with a better outcome at first relapse. METHODS All pts were at first recurrence following consolidation of CR1 with (i) high-dose Ara-C (HiDAC) multicycle therapy supported by blood stem cells (standard risk, as defined by mixed clinico-cytogenetic criteria) or (ii) allo-SCT in case of high-risk prognostic profile. Median pt age was 55 y (range 21–68). CR1 duration was ≤ 6 months in 49 pts (34%), ranging from 0.6 to 6 mo (median 3.7). 25/68 pts (37%) had an unfavourable cytogenetics (CG), and 8.2 % had MDS-related AML. 96 pts (66%) had received HiDAC and 21 (15%) an allo-SCT according to study design. RESULTS 105 pts (72%) received salvage chemotherapy, 10 pts (7%) underwent directly allo-SCT, while the remaining 30 (21%) received palliation and all of them died. Salvage therapy consisted again of HiDAC alone or in combination with fludarabine or anthracyclines. After reinduction, 52/105 pts (49.5%) achieved CR2 and 15 (14%) died of complications. Altogether, 42 pts (29%, group 1) received an allo-SCT following relapse, 27 (64%) in CR2, 5 beyond CR2 and 10 soon after relapse. Of 20 more pts (14%, group 2) in CR2 but without HLA identical donor, 13 could be given further intensive consolidation therapy. Both groups were comparable regarding adverse prognostic features such as age >55 y, WBC count>50,000/μL, unfavourable CG, presence of FLT-3 ITD, prior allo-SCT and 1st CR lasting ≤ 6 mo. At the end of treatment, 37/42 pts (88%) receiving SCT and all 20 pts (100%) given only chemotherapy were in CR2. Logistic regression analysis showed that intensive treatment without HiDAC at induction (p=0.04) as well as CR1 lasting <6 mo (p=0.01) negatively affected CR2 rate. Median duration of CR2 was 7.5 mo (range 1–49) in group 1 compared to 4 mo (range 1–15) in group 2. Day 100 non-relapse mortality in the 2 groups was 7% and 10%. After a median follow-up of 9.4 mo in group 1 (range 3–49) and 10 mo in group 2 (range 2–65), 2-y OS was 24% and 15.5%, respectively. Notably, 2-y OS in allo-SCT group ranged from 42% in pts ≤ 45 years to 14% in older ones. Moreover, survival was affected by risk category. In fact 2-y OS of 14/37 (38%) standard risk pts undergoing allo-SCT at salvage was 41% vs 17% in 28/108 (26%) comparable high risk pts. Cox regression analysis revealed achievement of CR2 being the only independent prognostic factor related to overall survival (p=0.0001). CONCLUSIONS AML patients receiving intensive chemotherapy including HiDAC at 1st relapse reached a high CR2 rate, regardless of type of prior risk-adapted consolidation. Further intensification with allo-SCT may offer substantial salvage rates to younger standard risk patients, thus adding value to the underlying concept of a risk-oriented first-line therapy.
