Nomogram for Prediction of Postoperative Morbidity in Patients with Colon Cancer Requiring Emergency Therapy.

BACKGROUND Postoperative complications are the major cause of mortality and prolonged hospitalization after emergency surgery for colon cancer. This study aimed to propose an effective nomogram to predict postoperative complications in order to improve the outcomes. MATERIAL AND METHODS We retrospectively analyzed 449 patients who underwent emergency surgery for complicated colon cancer at the County Emergency Hospital Clinic "St. Apostle Andrei" in Galati, in the period from 2008 to 2017. Postoperative complications were intestinal obstruction, leakage, bleeding, peritonitis, wound infection, surgical wound dehiscence, respiratory failure, heart failure, acute renal failure, sepsis, and Clostridium difficile colitis, within a month after surgery. Logistic regression models were used to identify the independent prediction factors, and a nomogram was created, based on the best model. RESULTS A total of 106 patients (21%) presented postoperative complications after emergency surgery for colon cancer; 51 patients (11.36%) died during the postoperative period. After identifying the risk factors through univariate regression analysis, we identified the independent prediction factors in 2 multivariate regression models. The model with the highest accuracy included the following 7 independent prediction factors: Eastern Cooperative Oncology Group performance status, Charlson score, white blood cell count, electrolyte and coagulation disorders, surgery time, and cachexia (P<0.05 for all). This model showed good precision in predicting postoperative complications, with an area under curve of 0.83 and ideal accordance between the predicted and observed probabilities. CONCLUSIONS The nomogram developed in this study, which was based on a multivariate logistic regression model, had good individual prediction of postoperative complications.

Additional Prognostic Value of Tissue Doppler Evaluation in Patients with Aortic Stenosis and Left-Ventricular Systolic Dysfunction Undergoing Aortic Valve Replacement.

Background and Objectives: Patients with surgical aortic stenosis (AS) show impaired diastolic filling, which is a risk factor for early and late mortality after aortic valve replacement (AVR). There is a paucity of information concerning the impact of restrictive diastolic filling and the evolution of diastolic dysfunction in the early and medium terms post-AVR. We aimed to determine the prognostic value of the presence of a restrictive left-ventricular (LV) diastolic filling pattern (LVDFP) and dilated left atrium (LA) in patients with AS and LV systolic dysfunction (LVEF < 40%) who underwent AVR, and to define the independent predictors for immediate and long-term prognosis and their value for preoperative risk estimation. Materials and Methods: The study was prospective and included 197 patients with surgical AS and LVEF <40% who underwent AVR. Preoperative echocardiographic examinations were repeated at day 10, at 1, 3 and 6 months, and at 1 and 2 years after surgery, with evaluation of LVEF, diastolic function and LA dimension index (mm/m2). Depending on LV systolic performance, patients were classified as Group A (LVEF: 30−40%) or Group B (LVEF < 30%). Results: The main echographic independent parameters for early and late postoperative death were: restrictive LVDFP, significant pulmonary hypertension, LV end-systolic diameter (LVESD) >55 mm and the presence of second-degree mitral regurgitation. Restrictive LVDFP and LA dimension >30 mm/m2 were independent predictors for fatal outcome (p = 0.0017). Conclusions: Assessment of diastolic function and LA dimension are reliable parameters in predicting fatal outcome and hospitalization for heart failure, having an independent and incremental prognostic value in patients with surgical AS. Complete evaluation of LVDFP with all the echographic measurements (including TDI) should routinely be part of the preoperative assessment of patients with LV systolic dysfunction undergoing AVR.

PD-L1 Expression in Esophageal and Gastroesophageal Junction Carcinoma, Correlation with the Immune Infiltrate - Preliminary Study.

Background: Although traditional management for esophageal and esogastric cancer has been improved, survival at 5 years is still low, and immunotherapy could be a way to improve it. In addition to the predictive value of the response to immunotherapy, PD-L1 also has a known prognostic value. We aimed to evaluate the immunohistochemical expression of PD-L1, CD8+ T-cell, and CD4/CD25+ T-cell (Tregs) infiltration and their relationship in esophageal and gastroesophageal junction carcinoma. Material and Methods: Endoscopic biopsies were analyzed in 14 patients with esophageal cancer or esogastric junction, before starting the neoadjuvant treatment, hospitalized from the period 2019- to 2021 in the St. Mary's Clinical Hospital, Bucharest. Immunohistochemical tests were performed to investigate the expression of lymphocyte intratumoral infiltrate markers. Results: Of the 14 cases, 13 (93%) were male, and 1 (7%) were female. Histological, 4 cases were adenocarcinomas, and 10 cases were squamous cell carcinomas. 10 cases showed epithelial PD-L1 positivity (78%). Using a quantitative evaluation of PD-L1 we obtained a statistical correlation between the median values of this marker with the expression of CD8. There was obtained a statistical correlation between PD-L1 positivity and low expression of CD4 or CD4+/CD25 T cells. Conclusions: PD-L1 is expressed in tumors with higher CD8+ T cell densities and lower CD4/CD25 positive cells (Tregs), indicating that the good prognosis of PD-L1-positive tumors could be due to the inhibition of CD4 / CD25-positive cells (Tregs) rather than the stimulation of CD8-positive T cells, by an adaptive immune resistance mechanism.

Abberant Immunohistochemical Expression of OCT3/4 and EMT Related Markers, Vimentin and E-cadherin, is Correlated with Adverse Histopathological Features in Colorectal Adenocarcinoma.

Background: Although clinical management for colorectal cancer has been markedly improved, it is faced with a growing incidence among the young and among those in developing nations. Furthermore, diagnosis occurs mostly in advanced stages, when the therapeutic resources are limited. Therefore we need new biomarkers for diagnostics and therapeutic targets. The key event that leads to invasion and metastasis is the epithelial to mesenchymal transition (EMT), which can be studied with IHC markers. We aimed to corelate the expression of EMT related markers (Vimentin and E-cadherin) and a stem cell marker (OCT 3/4) with the clinicopathological parameters of the tumors. Material and Methods: Surgical resection specimens from 30 treatment-naive colon cancer patients, hospitalized from 2018 to 2021 were assessed. Immunohistochemical tests were performed to investigate the expression of EMT related markers and OCT 3/4 in tumor cells. Results: Vimentin, OCT3/4 positivity and loss of E-cadherin were significantly associated with tumor grade, tumor budding, invasive tumor front, and lymph node metastasis. Conclusions: Vimentin, E-cadherin and OCT 3/4 might serve as a panel of biomarkers that can aid in the prognostication of patients, with the added potential of being oncotargets.

Challenges and Solutions in Choosing the Surgical Treatment in Patients with Complicated Colon Cancer Operated in an Emergency - A Retrospective Study.

Introduction: Choosing the optimal treatment for patients with complicated colon cancer operated in an emergency remains a challenge. The study aims to identify the factors that influence the therapeutic decision in these patients. Patients and Methods: We included in this retrospective study 449 patients operated in emergency for complicated colon cancer, in the Clinical Emergency County Hospital "St. Ap. Andrei" Galati between 2008-2017. The patients data were collected from the observation sheets, the surgical, imaging and laboratory protocols. Results: The operations performed were: resections with a stoma in 37.63% of cases, resections with anastomosis in 36.97%, stomas in 16.26% and internal derivations in 9.13% of patients. Elderly age was correlated with stomas with or without tumour resection (p 0.05). Preoperative diagnosis of IDH was associated with resections with anastomosis, those with occlusion were associated with internal derivations and those with digestive perforations with resections with a stoma (p 0.05). The stomas were associated with the presence of intraoperatively detected complications (p 0.05). Conclusions: Complicated colon tumours operated on in an emergency require surgical treatment tailored to each patient. It is important to choose the type of treatment taking into account the patient's condition at admission, clinical-paraclinical data, tumour location, tumour complication and the presence of other complications detected intraoperatively.

Continuous Noninvasive Hemoglobin Monitoring Reflects the Development of Acute Hemodilution After Consecutive Fluid Challenges.

BACKGROUND: Consecutive fluid challenges (FCs) are frequently administered to maximize the stroke volume (SV) as part of a goal-directed therapy (GDT) strategy. However, fluid administration may also cause acute hemodilution that might lead to an actual paradoxical decrease in oxygen delivery (DO2). The aim of this study was to examine whether continuous noninvasive hemoglobin (SpHb) monitoring can be used to detect the development of acute hemodilution after graded fluid administration. METHODS: In 40 patients who underwent major vascular or gastrointestinal surgery, an FC, consisting of 250 mL colloid solution, was administered. When the SV increased by ≥10%, the FC was repeated up to a maximum of 3 times. Laboratory-measured hemoglobin concentrations (BHb), SpHb, SV, cardiac output (CO), and DO2 values were recorded after each FC. RESULTS: All 40 patients received the first FC, 32 patients received the second FC, and 20 patients received the third FC (total of 750 mL). Out of the 92 administered FCs, only 55 (60%) caused an increase in SV ≥10% ("responders"). The first and the second FCs were associated with a significant increase in the mean CO and DO2, while the mean SpHb and BHb decreased significantly. However, the third and last FC was associated with no statistical difference in CO and SV, a further significant decrease in mean SpHb and BHb, and a significant decrease in DO2 in these patients. Compared to their baseline values (T0), BHb and SpHb decreased by a mean of 5.3% ± 4.9% and 4.4% ± 5.2%, respectively, after the first FC (T1; n = 40), by 9.7% ± 8.4% and 7.9% ± 6.9% after the second FC (T2; n = 32), and by 14.5% ± 6.2% and 14.6% ± 5.7% after the third FC (T3; n = 20). Concordance rates between the changes in SpHb and in BHb after the administration of 250, 500, and 750 mL colloids were 83%, 90%, and 100%, respectively. CONCLUSIONS: Fluid loading aimed at increasing the SV and the DO2 as part of GDT strategy is associated with acute significant decreases in both BHb and SpHb concentrations. When the administration of an FC is not followed by a significant increase (≥10%) in the SV, the DO2 decreases significantly due to the development of acute hemodilution. Continuous noninvasive monitoring of SpHb does not reflect accurately absolute BHb values, but may be reliably used to detect the development of acute hemodilution especially after the administration of at least 500 mL of colloids.

Prognostic Factors in Advanced Ovarian Cancer - A Clinical Trial.

Introduction: Ovarian cancer is one of most fatal gynecological condition. The number of patients diagnosed in advanced stages is very high, hence the recurrence rate is high, and the chance of survival at 5 years is less than 45%. Purpose: To evaluate correspondance between overall survival with clinical, paraclinical, tumor or treatment characteristics and to identify prognostic factors in patients with advanced ovarian cancer - stage III and IV FIGO. Material and Method: We performed a retrospective study in 65 patients with advanced ovarian cancer - stages III and IV FIGO operated during 2010-2018, with a follow-up period of at least one year. There were correlations with clinical and paraclinical charateristics, tumor or treatment characteristics and with overall survival. Results: In the univariate statistical analysis of survival, a significant statistical association is obtained by the presence of pelvic pain at presentation (p_value = 0.033744), with the stage III (p_value = 0.007595, respectively p_value = 0.022090), with the type of citoreduction (p_value = 0.035) , with postoperative complications (p_value = 0.000685) within the pathological subtypes (p_value = 0.046266), with adjuvant treatment (p_value = 0.000083). Cox multivariate regression analysis showed that adjuvant chemotherapy (HR = 0.046, 95% CI = (0.008, 0.261), (p_value = 0.000492), suboptimal cytoreduction (HR = 0.346, 95% CI = (0.140, 0.853), (p_value) = 0.021219) and postoperative complications (HR = 53,751, 95% CI = (4,672, 618,365), (p_value = 0.001389) are independent prognostic factors. Conclusions: Absence of pelvic pain at diagnosis, FIGO IIIC stage, suboptimal cytoreduction, presence of postoperative complications, inadequate adjuvant treatment and pathological type of clear cell cancer have been shown to be prognostic factors for overall survival. In patients with advanced ovarian cancer, the type of optimal citoreduction and adjuvant treatment are independent protective factors for overall survival, and the presence of postoperative complications has been shown to be an independent risk factor.

The Influence of the Type of Surgery on the Immediate Postoperative Results in Patients with Colorectal Cancer Operated in Emergency.

The emergency surgery for colorectal cancer is associated with high rates of morbidity and mortality due to factors related to the characteristics of the patients but also the therapeutic attitude. This study aims to identify the surgical interventions associated with the postoperative complications, with the main causes of morbidity, with the reinterventions and with the postoperative deaths. We included in this retrospective study 431 patients hospitalized and operated in an emergency for complicated colorectal malignant tumors in the Surgery II Clinic of the Clinical Emergency County Hospital "Sf. Ap. Andrei from Galati, in the period 2008-2017. The patients data were collected from observation sheets, operative protocols, pathological, imaging and laboratory bulletins, at the time of the emergency intervention, as well as from those of subsequent admissions in patients who benefited from serial interventions. The postoperative morbidity was 10.44%. The resections with anastomosis were associated with the presence of postoperative complications (p 0.01): pseudomembranous colitis, (p 0.01) and postoperative intestinal occlusion (p 0.01). The practice of lymph node dissection was associated with postoperative complications (p 0.01): pseudomembranous colitis (p 0.01) and intestinal occlusion (p 0.01). The reinterventions were associated with resections with anastomosis (p 0.01), lymph node dissection (p 0.01) or patients with open /semi-open abdomen (p 0.04). The postoperative mortality was 9.28%. It was associated with the practice of lymph node dissection (p 0.01), of the ileostomy (p 0.01), with the open /semi-open abdomen (p 0.04). Patients with colostomy had the lowest number of hospitalization days (p 0.01). The resections with anastomosis per primam and the lymph node dissection were associated with morbidity. The type of main surgery did not influence the postoperative mortality, this being associated with the concomitant surgery: the lymph node dissection, the ileostomy, and the abdomen closure type. The reinterventions were associated with resections with anastomosis per primam, with lymph node dissection and with the open /semi-open abdomen. The duration of hospitalization was significantly shorter in patients with a colostomy.

The Importance of Systemic Inflammation Markers in the Survival of Patients with Complicated Colorectal Cancer, Operated in Emergency.

Introduction: The inflammatory response plays a critical role in carcinogenesis. There are recent scores based on the systemic inflammatory response, such as neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), lymphocyte/monocyte ratio (LMR), which have been shown to have prognostic value in cancer patients. These scores allow the identification of patients who will have poor response to treatment and poor survival. The aim of this study is to evaluate the prognostic role of NLR, PLR, LMR and PNI in terms of long-term survival in patients with colorectal cancer, operated in emergency. Material and Methods: We included 391 patients admitted and operated for complicated colorectal cancer in the Surgery II clinic of the Clinical Emergency County Hospital Sf. Ap. Andrei - from Galati, between 2008-2017. We analyzed the paraclinical factors of systemic inflammation NLR, PLR, MRL and PNI. As prognostic factors, survival curves were analyzed. Results: The high values of NLR and PLR increased the risk of death (HR = 7.581, 95% CI = (6.358,9.039), p value = 0.000000, respectively HR = 1.043, 95% CI = (1.039, 1.047), p value = 0.000000), and the increased values of LMR and PNI led to the decrease of this risk (HR = 0.069, 95% CI = (0.054.0.090), p value = 0.000000, respectively HR = 0.758, 95 % CI = (0.730.0.788), p value = 0.000000). In the multivariate regression analysis, the increase of PLR resulted in an increase in the risk of death (HR = 1.024, 95% CI = (1.019.1.029), p value = 0.000000), and for the LMR and PNI, a reduction of the risk of death (HR = 0.353, 95% CI = (0.248.0.504), p value = 0.000000, respectively HR = 0.852, 95% CI = (0.822.0.883), p value = 0.000000). Conclusions: The univariate analysis showed that NLR and PLR are risk factors, and LMR and PNI are protective factors in terms of survival. The multivariate analysis revealed that PLR is an independent risk factor, and LMR and PNI were independent protection factors.

Analysis of Prognostic Factors in Complicated Colorectal Cancer Operated in Emergency.

Introduction: In 2018, the colon cancer was the 5th type of neoplasia regarding the cancer mortality and the rectal cancer was the 10th. The survival of patients with colorectal cancer operated in emergency still remains unsatisfactory, the death being due to local recurrences and to metastases. The aim of this study is to evaluate some correlations of overall survival with clinic and paraclinic features, tumor or treatment characteristics in order to identify prognostic factors, for cases with colorectal tumors that underwent emergency surgery. Material and Methods: We performed a retrospective analysis on 431 patients with colorectal cancer operated in emergency between 2008-2017, excluding 40 patients with postoperative deaths, with a follow-up period of at least one year. There were correlations of some clinic and paraclinic features, tumor or treatment characteristics with the overall survival. Results: In the univariate statistical survival analysis, a statistically significant association was obtained with: the age 61 years (p_value = 0.000049), abdominal surgical history (p_value = 0.031725), heart disease (p_value = 0.000007), atrial fibrillation (p_value = 0.007496), preoperative diagnosis (p_value = 0.034352), cachexia (p_value = 0.000000), oliguria (p_value = 0.000000), anemia (p_value = 0.000006) hydro-electrolytic disorders (p_value = 0.000001), tumor localization (p_value = 0.000030), invasion into other organs (p_value = 0.000000), appearance of "frozen pelvis" (p_value = 0.000000), peritoneal carcinomatosis (p_value = 0.000000), liver metastases (p_value = 0.000000), type of surgery (p_value = 0.000000), lymph node dissection (p_value = 0.000001), liver biopsy (p_value = 0.043483), stoma reversal (p_value = 0.000000 ), serial interventions (p_value = 0.000000), pTNM (p_value = 0.000000), tumor grading (p_value = 0.007069). The Cox multivariate regression analysis revealed that: the age 61 years - HR = 1,026, 95% CI (1,012, 1,039) (p value = 0.000139), cachexia - HR = 1,358, 95% CI (1,046, 1,764) (p value = 0.021617), peritoneal carcinomatosis - HR = 2.346, 95% CI (1.163, 4.732) (p_value = 0.017253), disease stage - HR = 36.745, 95% CI (14.778, 91.366) (p_ value = 0.000000), intervention type - HR = 0.187, 95% CI (0.045, 0.779) (p_ value = 0.021281) and serial interventions - HR = 0.282, 95% CI (0.144.0.551) (p_ value = 000213) are independent prognostic factors. Conclusions: The prognostic factors for patients with colorectal cancers operated in emergency are: the age 61, the presence of abdominal surgical history and associated cardiac conditions, especially atrial fibrillation, diagnosis of diastatic perforation imminence, cachexia, oliguria, hydro-electrolytic disorders at admission, rectal tumors, tumor invasion in other organs, the appearance of "frozen pelvis", the presence of liver metastases or peritoneal carcinomatosis, undifferentiated tumors, stage IV, practicing an internal derivation or not performing lymph node dissection. The age over 61, cachexia, as well as peritoneal carcinomatosis, stage III or IV are independent risk factors the Hartmann procedure and the serial interventions are independent protective factors.

Neoadjuvant Radiochemotherapy for Patients with Locally Advanced Esophagogastric Junction Adenocarcinoma.

SCOPE: neoadjuvant RCT influence on early and long term postoperative outcomes in patients with locally advanced esophagogastric junction adenocarcinomas. MATERIALS AND METHOD: Sixty two patients with locally advanced esophagogastric junction adenocarcinomas were treated at the Center of Excellence in Esophageal Surgery at St. Mary Hospital between 2010-2017. According to the Siewert classification, the group comprised of type I - 11 patients, type II - 18 patients and type III - 33 patients. Only 17 patients received preoperative RCT. The surgical treatment for the 62 resected patients was: abdominal extended gastrectomy - 40 patients, Ivor-Lewis - 13 patients, McKeown esophagogastrectomy (3 incisions) - 5 patients and transhiatal esophagectomy - 4 patients. Results: Postoperative morbidity was 46.77% and was mainly represented by fistulas in 17 patients and pulmonary complications such as pleurisy,pneumonia and ARDS in 12 patients. Fistula occurred in 15 cases: grade 1 - 2 patients, grade 2 - 10 patients, grade 3 - 5 patients. Postoperative mortality was 4.8% (p_value = 0.017980 Fisher's Exact Test). Downstaging was observed in 7 patients. I did not encounter statistically significant differences in long term survival. Conclusions: Neoadjuvant RCT had no impact on postoperative morbidity, but statistically influenced postoperative mortality.

Zenker Diverticulum Treatment: Endoscopic or Surgical?

Introduction: The Zenker Diverticulum is a rare pathology, the selection of patients for invasive treatments is questionable, as well as the applied therapeutic method. The aim of the study is to evaluate the main methods of classical and endoscopic surgical treatment in this pathology and to correlate pathophysiological aspects with clinical consequences. MATERIAL AND METHOD: We included 36 patients with Zenker hypopharyngeal diverticulum treated in 2010/2017 in two university clinics: 7 patients by classical surgical approach at the General and Esophageal Surgery Clinic of St. Mary's Hospital Bucharest and 29 patients with endoscopic approach at Department of Diagnostic and Interventional Digestive Endoscopy of the Regional Institute of Hepatology and Gastroenterology Prof Dr Octavian Fodor, Cluj-Napoca. The age of the patients ranged from 42 to 84 years and in the 7th to 15th decade. Results: Cricopharyngeal myotomy was performed in all patients. Diverticullectomy was performed in 7 patients treated surgically. The average hospitalization duration was 4 days. Intra-procedural complications showed 3 patients treated endoscopically and consisted of laminar haemorrhage. Two patients were treated with endoscopic endoscopic hemostasis and hot pens and one patient had endoscopic hemostasis with clips. The post-procedural complications were: local pain, leukocytosis, melena, fever, cervical hematoma. These post-treatment events were seen in 6 patients. The posttreatment morbidity was 16.66%. Conclusions: In patients included in the batch, the endoscopic treatment efficiency was 80%. Peristent postinterventional symptomatology was mainly represented by dysphagia, post-procedural syndrome was associated with dysphagia persistence. Patients with persistent post-surgical symptoms were required to reintervention.

Present tendencies of elective caesarean delivery in Romania: Geographic, social and economic factors.

The literature review was conducted to identify the causes of the rising incidence of caesarean section (CS) cases in Romania, and to create a database and a measurement plan to quantify the amount of CS on maternal request and the influence of geographical, social and economic factors. The review was conducted at the Department of Obstetrics and Gynaecology Clinical Emergency Hospital Sf Pantelimon, Bucharest, and comprised figures of clinical records of all patients who underwent CS between 2009 and 2014. The results showed an increase in the number of CS on maternal requests. In 2014 it reached a rate of 36.90 cases in every 100 newborn infants, which was 2.62% higher than 2013. Increasing rate of CS seemed to have resulted from a few factors, including the constant preoccupation to improve the obstetrical field in Romania; its services; the prophylactic measures in obstetrics; the trials to prevent the fear of the obstetrical malpraxis and its risks and consequences; and the fact that some obstetricians have done multiple CS deliveries on maternal requests.

PLUNC proteins positivity in patients with chronic rhinosinusitis: a case-control study.

INTRODUCTION: Innate immunity is the first protection against microorganisms. Nowadays, there is a growing interest in innate immune molecule known as palate, lung, nasal epithelial clone (PLUNC). PLUNC is a specific product of the airways, of approximately 25 kDa, encoded by adjacent genes found within a 300 kb region of chromosome 20; these proteins must be detected predominantly in the upper respiratory tract. MATERIALS AND METHODS: We performed a case-control study to investigate the presence of this protein in nasal tissue of patients affected by chronic rhinosinusitis. 59 patients were enrolled (44 cases, 15 controls). We have examined the correlation between the presence of pathology and the PLUNC proteins positivity. RESULTS: 100% of controls have a +++ rated PLUNC proteins positivity, while cases have a lower percentage of positivity. We used χ (2) statistical test to analyze the results of the study and there is a difference statistically significant between cases and controls in PLUNC proteins positivity. CONCLUSIONS: These observations suggest that, in response to agents or chemical factors, nasal mucosal epithelium will react and produce PLUNC proteins. So PLUNC proteins have a protective function on upper airways mucosa, as we can see by evaluating the high positivity in control group.

Challenges Regarding the Value of Routine Perioperative Transesophageal Echocardiography in Mitral Valve Surgery.

BACKGROUND AND OBJECTIVES: Transesophageal echocardiography (TEE) is considered an indispensable tool for perioperative evaluation in mitral valve (MV) surgery. TEE is routinely performed by anesthesiologists competent in TEE; however, in certain situations, the expertise of a senior cardiologist specializing in TEE is required, which incurs additional costs. The purpose of this study is to determine the indications for specialized perioperative TEE based on its utility and the correlation between intraoperative TEE diagnoses and surgical findings, compared with routine TEE performed by an anesthesiologist. MATERIALS AND METHODS: We conducted a three-year prospective study involving 499 patients with MV disease undergoing cardiac surgery. Patients underwent intraoperative and early postoperative TEE and at least one other perioperative echocardiographic evaluation. A computer application was dedicated to calculating the utility of each type of specialized TEE indication depending on the type of MV disease and surgical intervention. RESULTS: The indications for performing specialized perioperative TEE identified in our study can be categorized into three groups: standard, relative, and uncertain. Standard indications for specialized intraoperative TEE included establishing the mechanism and severity of MR (mitral regurgitation), guiding MV valvuloplasty, diagnosing associated valvular lesions post MVR (mitral valve replacement), routine evaluations in triple-valve replacements, and identifying the causes of acute, intraoperative, life-threatening hemodynamic dysfunction. Early postoperative specialized TEE in the intensive care unit (ICU) is indicated for the suspicion of pericardial or pleural effusions, establishing the etiology of acute hemodynamic dysfunction, and assessing the severity of residual MR post valvuloplasty. CONCLUSIONS: Perioperative TEE in MV surgery can generally be performed by a trained anesthesiologist for standard measurements and evaluations. In certain cases, however, a specialized TEE examination by a trained senior cardiologist is necessary, as it is indirectly associated with a decrease in postoperative complications and early postoperative mortality rates, as well as an improvement in immediate and long-term prognoses. Also, for standard indications, the correlation between surgical and TEE diagnoses was superior when specialized TEE was used.

Laparoscopic Esocardiomyotomy-Risk Factors and Implications of Intraoperative Mucosal Perforation.

BACKGROUND: Mucosal perforation during laparoscopic esocardiomyotomy is quite frequent, and its consequences cannot always be neglected. The purpose of the study is to investigate the risk factors for intraoperative mucosal perforation and its implications on the postoperative outcomes and the functional results three months postoperatively. MATERIAL AND METHODS: We retrospectively identified the patients with laparoscopic esocardiomyotomy performed at Sf. Maria Hospital Bucharest, in the period between January 2017-January 2022 and collected the data (preoperative-clinic, manometric and imaging, intra-and postoperative). To identify the risk factors for mucosal perforations, we used logistic regression analysis. RESULTS: We included 60 patients; intraoperative mucosal perforation occurred in 8.33% of patients. The risk factors were: the presence of tertiary contractions (OR = 14.00, 95%CI = [1.23, 158.84], p = 0.033206), the number of propagated waves ≤6 (OR = 14.50), 95%CI = [1.18, 153.33], p < 0.05), the length of esophageal myotomy (OR = 1.74, 95%CI = [1.04, 2.89] p < 0.05), the length of esocardiomyotomy (OR = 1.74, 95%CI = [1.04, 2.89] p < 0.05), and a protective factor-the intraoperative upper endoscopy (OR = 0.037, 95%CI = [0.003, 0.382] p < 0.05). CONCLUSIONS: Identifying risk factors for this adverse intraoperative event may decrease the incidence and make this surgery safer. Although mucosal perforation resulted in prolonged hospital stays, it did not lead to significant differences in functional outcomes.

A Novel Clinical Nomogram for Predicting Overall Survival in Patients with Emergency Surgery for Colorectal Cancer.

BACKGROUND: Long-term survival after emergency colorectal cancer surgery is low, and its estimation is most frequently neglected, with priority given to the immediate prognosis. This study aimed to propose an effective nomogram to predict overall survival in these patients. MATERIALS AND METHODS: We retrospectively studied 437 patients who underwent emergency surgery for colorectal cancer between 2008 and 2019, in whom we analyzed the clinical, paraclinical, and surgical parameters. RESULTS: Only 30 patients (6.86%) survived until the end of the study. We identified the risk factors through the univariate Cox regression analysis and a multivariate Cox regression model. The model included the following eight independent prognostic factors: age > 63 years, Charlson score > 4, revised cardiac risk index (RCRI), LMR (lymphocytes/neutrophils ratio), tumor site, macroscopic tumoral invasion, surgery type, and lymph node dissection (p < 0.05 for all), with an AUC (area under the curve) of 0.831, with an ideal agreement between the predicted and observed probabilities. On this basis, we constructed a nomogram for prediction of overall survival. CONCLUSIONS: The nomogram created, on the basis of a multivariate logistic regression model, has a good individual prediction of overall survival for patients with emergency surgery for colon cancer and may support clinicians when informing patients about prognosis.

Incidence and Risk Factors for Long-Term Persistence of Diastolic Dysfunction after Aortic Valve Replacement for Aortic Stenosis Compared with Aortic Regurgitation.

(1) Background: Severe left ventricular (LV) diastolic dysfunction with a restrictive diastolic pattern (LVDFP) is generally associated with a worse prognosis. Its evolution and reversibility in the short- and medium-term after aortic valve replacement (AVR) has been little-studied. We aimed to evaluate the evolution of LV remodeling and LV systolic and diastolic function after AVR in aortic stenosis (AS) patients compared to aortic regurgitation (AR). Moreover, we tried to identify the main predictive parameters for postoperative evolution (cardiovascular hospitalization or death and quality of life) and the independent predictors for the persistence of restrictive LVDFP after AVR. (2) Methods: A five-year prospective study on 397 patients undergoing AVR for AS (226 pts) or AR (171 pts), evaluated clinically and by echocardiography preoperatively and until 5 years postoperatively. (3) Results: 1. In patients with AS, early post AVR, LV dimensions decreased and diastolic filling and LV ejection fraction (LVEF) improved more rapidly compared to patients with AR. At 1 year postoperatively, persistent restrictive LVDFP was found especially in the AR group compared to the AS group (36.84% vs. 14.16%). 2. Cardiovascular event-free survival at the 5-year follow-up was lower in the AR group (64.91% vs. 87.17% in the AS group). The main independent predictors of short- and medium-term prognosis after AVR were: restrictive LVDFP, severe LV systolic dysfunction, severe pulmonary hypertension (PHT), advanced age, severe AR, and comorbidities. 3. The persistence of restrictive LVDFP after AVR was independently predicted by: preoperative AR, the E/Ea ratio > 12, the LA dimension index > 30 mm/m2, an LV endsystolic diameter (LVESD) > 55 mm, severe PHT, and associated second-degree MR (p < 0.05). (4) Conclusions: AS patients had an immediate postoperative evolution in terms of LV remodeling, and LV systolic and diastolic function were more favorable compared to those with AR. The restrictive LVDFP was reversible, especially after the AVR for AS. The main prognostic predictors were the presence of restrictive LVDFP, advanced age, preoperative AR, severe LV systolic dysfunction, and severe PHT.

The Profile and All-Cause In-Hospital Mortality Dynamics of St-Segment Elevation Myocardial Infarction Patients during the Two Years of the COVID-19 Pandemic.

During the coronavirus pandemic 2019 (COVID-19), some studies showed differences in the profile of subjects presenting with acute coronary syndromes as well as in overall mortality due to the delay of presentation and other complications. The purpose of this study was to compare the profile and outcomes, with emphasis on all-cause in-hospital mortality, of ST-elevation myocardial infarction (STEMI) subjects presenting to the emergency department during the pandemic period compared with a control group from the previous year, 2019. The study enrolled 2011 STEMI cases, which were divided into two groups-pre-pandemic (2019-2020) and pandemic period (2020-2022). Hospital admissions for a STEMI diagnosis sharply decreased during the COVID-19 period by 30.26% during the first year and 25.4% in the second year. This trend was paralleled by a significant increase in all-cause in-hospital mortality: 11.5% in the pandemic period versus 8.1% in the previous year. There was a significant association between SARS-CoV-2 positivity and all-cause in-hospital mortality, but no correlation was found between COVID-19 diagnosis and the type of revascularization. However, the profile of subjects presenting with STEMI did not change over time during the pandemic; their demographic and comorbid characteristics remained similar.

Telemedicine for Optimizing Secondary Prevention in Coronary Artery Bypass Grafting Patients during COVID-19 Pandemic.

(1) Background: The COVID-19 pandemic has introduced a major disruption to the delivery of secondary prevention measures in patients with established atherosclerotic cardiovascular disease (CVD). It required a rapid and widespread adoption of new medical services, including the use of telemedicine. This study aimed to examine the impact of COVID-19 on secondary prevention in patients with coronary artery bypass grafting (CABG) and to evaluate the effectiveness of the telemedicine application for the implementation of lifestyle change measures, remote monitoring, and treatment regimen adjustment; (2) Methods: This prospective study on 194 CABG patients evaluated three consecutive years between 2019 and 2022 in the pre-pandemic period by face-to-face visits and during the pandemic by teleconsultations or hybrid follow-up. Variables of interest were compared between four periods: pre-pandemic-pre-P (1 March 2019-29 February 2020), lockdown-Lock (1 March-31 August 2020), restrictive-pandemic-Restr-P (1 September 2020-28 February 2021), and relaxed-pandemic-Rel-P (1 March 2021-1 March 2022). (3) Results: The average values of the lipidogram, blood sugar, and uric acid increased during Lock and Restr-P, but, through the use of teleprevention, they returned to the pre-pandemic level or even below this level. The exception was blood sugar, which remained high in Rel-P. The number of newly diagnosed patients with diabetes also increased, with most of them having moderate forms of COVID. During Lock and Res-P, the percentage of obese, smoking, or hypertensive patients increased, but, through the use of teleprevention, we managed to reduce it, although it remained slightly higher than the pre-pandemic level. Physical activity decreased in the first year of the pandemic, but, in Rel-P, CABG patients became more active than before the pandemic (4) Conclusions: The use of telemedicine for cardiovascular secondary prevention allowed us to not only continue seeing CABG patients but, also, to adjust their medication and to expand cardiovascular preventive counseling and testing with favorable results, especially during the second year of the pandemic.
