Clinical Characteristics of COVID-19 Patients and Risk Factors for Shortness of Breath: A Cross-Sectional Study in Bangladesh

Background: Exploring the clinical characteristics, and risk factors for severe complications among COVID-19-positive patients has been helpful in identifying the most vulnerable communities to which public healthpractitioners should pay special attention. This study aimed to evaluate the clinical characteristics of COVID-19 patients, and risk factors for shortness of breath among COVID-19-positive patients in Chattogram, Bangladesh.Materials and Methods: Data were collected using a structured and facilitator-administered questionnaire among the COVID-19-positive patients (N = 408). Multivariate logistic regression analysis was performed to explore the predictors of outcome variables. Data were analyzed using IBM SPSS version 24.0.Results: It was revealed that at least one comorbidity was found among about half of the study participants,while the most prevalent symptoms of COVID-19 patients consisted of fever, cough, loss of taste, loss of smell, fatigue, and sore pain. In addition, Azithromycin is a more common treatment in our country. The multivariate logistic regression displays the COVID-19 patients aged more than 50 years (AOR = 2.05, 95% CI: 1.13-3.71) and respondents with cardiovascular disease (AOR = 4.60, 95% CI: 1.51-8.58) and the second wave of the coronapandemic (AOR = 1.78, 95% CI: 1.06-2.99) were reported as a risk factor for having shortness of breath among the virus-infected people.Conclusion: The findings explored an empirical and practical basis for exploring the risk factors for severecomplications of COVID-19 patients. Furthermore, evidence from this study might play a key role in providingpolicymakers with research-based evidence in their continuous effort to prevent the COVID-19 pandemic.

Risk factors for severe complications and salvage management in direct-to-implant immediate breast reconstruction: A retrospective study.

Controversies regarding the risk factors affecting direct-to-implant (DTI) immediate breast reconstruction still exist. This study aimed to evaluate the risk factors for severe complications in DTI breast reconstruction and explore potential salvage management strategies. We conducted a retrospective review of 238 patients (240 breasts) who underwent DTI immediate breast reconstruction between 2011 and 2020. Multivariate logistic regression analyses were used to identify the risk factors predicting severe complications. Seventeen (7.08%) reconstructed breasts experienced severe complications, of which only 5 were successfully salvaged through surgical revision, while the others failed and resulted in implant removal. Multivariate analyses demonstrated that mesh use [odds ratio (OR) = 4.054, 95% confidence interval: 1.376-11.945, P = .011] and post-mastectomy radiotherapy (odds ratio = 4.383, 95% confidence interval 1.142-16.819, P = .031) were independent predictors of severe complications. Mesh use and post-mastectomy radiotherapy for breast reconstruction increase the risk of severe complications. Despite positive surgical treatment, the successful salvage rate was poor.

The Effect of Diabetes on Complications after Spinal Fusion: A Systematic Review and Meta-Analysis

ObjectiveSpinal fusion procedures are used to treat a wide variety of spinal pathologies. Diabetes mellitus (DM) has been shown to be a significant risk factor for several complications following these procedures in previous studies. To the authors’ knowledge, this is the first systematic review and meta-analysis elucidating the relationship between DM and complications occurring after spinal fusion procedures. MethodsSystematic literature searches of PubMed and EMBASE were performed from their inception to October 1, 2022, to identify studies that directly compared postfusion complications in patients with and without DM. Studies met the prespecified inclusion criteria if they reported the following data for patients with and without DM: (1) demographics; (2) postspinal fusion complication rates; and (3) postoperative clinical outcomes. The included studies were then pooled and analyzed. ResultsTwenty-eight studies, with a cumulative total of 18,853 patients (2,695 diabetic patients), were identified that met the inclusion criteria. Analysis showed that diabetic patients had significantly higher rates of total number of postoperative complications (odds ratio[OR]=1.33;95% confidence interval[CI]=1.12-1.58;p=.001), postoperative pulmonary complications (OR=2.01;95%CI=1.31-3.08;p=.001), postoperative renal complications (OR=2.20;95%CI=1.27-3.80;p=.005), surgical site infection (OR=2.65;95%CI=2.19-3.20;p<.001), and prolonged hospital stay (OR=1.67; 95%CI=1.47-1.90; p<.001). ConclusionsPatients with DM had a significantly higher risk of developing complications after spinal fusion, particularly pulmonary and renal complications, in addition to surgical site infections and had a longer length of stay. These findings are important for informed discussions of surgical risks with patients and families before surgery.

Presurgical mild anemia is a risk factor for severe postoperative complications of rectal cancer surgery: A Japanese nationwide retrospective cohort study.

Anemia has negative effects on long-term outcomes of rectal cancer patients; however, its status as a risk factor for severe complications is disputed. Perioperative risks may differ based on the severity of pre-surgical anemia; nonetheless, no previous study has investigated these differences. This study identified risks of severe postoperative complications in rectal cancer patients based on severity of their pre-surgical anemia. This study enrolled patients who underwent low anterior resection for rectal cancer and were registered in the Japanese National Clinical Database (NCD) between 2017 and 2019. Anemia severity was categorized into three levels: mild, moderate, and severe. A logistic regression model was applied to calculate the risk-adjusted odds ratio (OR) of severe complications after surgery. This study analyzed a cohort of 51 765 rectal cancer patients who underwent low anterior resection. Results showed that severe complications occurred in 10.9% of patients and were significantly more frequent in patients with anemia (13.6%) than those with normal hemoglobin levels (9.2%). Risk-adjusted ORs of severe complications in the severe, moderate, and mild anemia groups versus the normal group for males were 1.19 (95% confidence interval [CI]: 0.89-1.58), 1.47 (1.34-1.62), and 1.21 (1.12-1.31), respectively. Those for females were 1.39 (0.90-2.15), 1.64 (1.37-1.97), and 1.36 (1.16-1.58), respectively. According to this large cohort study, pre-surgical anemia significantly increases the risk of severe postoperative complications in rectal cancer patients. Even mild anemia presents a significant risk.

Effect of Preoperative Malnutrition Based on Albumin and BMI on Hepatocellular Carcinoma Surgery and Prediction of Risk Factors of Complications.

To investigate the correlation between preoperative malnutrition and perioperative variables in patients with hepatocellular carcinoma (HCC) and to analyze the risk factors of complications after HCC resection. All patients who underwent hepatectomy because of HCC in the First Affiliated Hospital of Chongqing Medical University from June 1, 2018, to December 1, 2021, were analyzed retrospectively. Preoperative malnutrition was defined as body mass index (BMI) < 18.5kg/m2 or serum albumin level < 3.5g/dL within 30days before operation. A total of 415 patients with HCC hepatectomy were included, and 75 (18.1%) were classified as malnutrition group. In the malnutrition group, blood loss (662.1 ± 748.1 VS 404.6 ± 681.9, P = 0.002), transfusion rate (36.0% VS 13.5%, P < 0.001), postoperative hospital stays (13.3 ± 9.6 VS 10.1 ± 4.2, P < 0.001), 30-day postoperative mortality (4.0 VS 0.6%, P = 0.043), complications rate (68% VS 34.8%, P < 0.001), and severe complication rate (17.3% VS 2.4%, P < 0.001) were significantly higher than those in the well-nourished group. Multivariate analysis showed that age (HR 1.037, 95% CI 1.015-1.059, P = 0.001), preoperative malnutrition (HR 2.933, 95% CI 1.515-5.679, P = 0.001), simultaneous cholecystectomy (HR 2.004, 95% CI 1.168-3.440, P = 0.012), cirrhosis (HR 4.997, 95% CI 2.864-8.718, P < 0.001), and transfusion (HR 5.166, 95% CI 2.272-11.748, P < 0.001) were independent risk factors for postoperative complications. In addition, preoperative malnutrition (HR 8.209, 95% CI 2.711-24.864, P < 0.001) and operation time (HR 1.088, 95% CI 1.003-1.103, P = 0.004) were independent risk factors for severe complications. Preoperative malnutrition can adversely affect the outcome of HCC resection. For patients with advanced age, cirrhosis, and malnutrition, preoperative planning is very important, and we should be more careful during the operation to avoid transfusion caused by bleeding and not to carry out preventive cholecystectomy, which are helpful to reduce the occurrence of postoperative complications.

Sickle Cell Trait and Mortality Risk: California Newborn Screening Longitudinal Follow up of Births 1991-2013

Sickle cell trait (SCT) represents a significant global public health issue with approximately three million carriers in United States and over 300 million worldwide. Yet, the mortality risk of sickle cell trait is unknown. Early anecdotal research on SCT led to social bias and stigmatization of individuals with the trait, which unfortunately hindered the conduct of well-designed morbidity and mortality studies in this population. This resulted in SCT being perceived as a benign asymptomatic condition that protects against malaria and its importance confined to the genetic risk for sickle cell disease. As research in SCT gradually increased, it became evident that SCT is indeed a risk factor for several complications including exertional related rhabdomyolysis, chronic kidney disease, venous thromboembolism, and other morbidities. SCT red cells in abnormal physiologic conditions sickle and can cause morbidity and mortality. Additionally, SCT could potentially influence the severity of various illnesses. Individuals with SCT commonly experience hyposthenuria and are at risk for dehydration which could further exacerbate the severity of many medical problems. It is essential to determine if SCT is a risk factor for overall mortality. This study is the first population-level investigation of all-cause mortality risk for individuals with SCT. This longitudinal analysis included all live births with SCT identified by the California newborn screening (NBS) program between 1991 and 2013. For each newborn with SCT, three matched controls with hemoglobin AA were randomly selected from the NBS cohort. Controls were matched to SCT cases on year of birth, sex, race/ethnicity, and city of birth. SCT records with incomplete data for the matched variables or those with fewer than three matching controls were excluded from the analysis. SCT cases and controls were linked to all deaths within the state of California for the years 1991-2013 using statewide death data files. Cox proportional hazard ratios and 95% confidence intervals were calculated to compare mortality between individuals with SCT and controls with hemoglobin AA, including stratified by age (&amp;lt;1, 1-4, 5-14, 15-22). The study identified 94,240 live births with SCT (Table 1), which represents 96% of all SCT live births identified by the California NBS program in 1991-2013, and 282,720 matched controls. Between 1991 to 2013, there were 693 (0.74%) SCT deaths and 1,910 (0.68%) control deaths. Those with SCT had an increased mortality hazard rate compared to those with hemoglobin AA (11% higher, p=0.015). When stratified by age, mortality hazard rates in the age strata 1-4 years (44% higher, p= .0009) and 5-14 years (48% higher, p=.0047) were higher than those with hemoglobin AA (Table 2). These age strata describe periods of follow up time, and an individual may appear in more than one stratum. Mortality hazard ratios calculated for each age stratum are conditional to individuals surviving to the starting age of that stratum. This analysis of mortality risk for a cohort of over 94,000 infants identified with SCT is the first of its kind and adds important information to the assessment of health risk for the condition. This is the first study that reports a higher risk of mortality for children and young adults with SCT compared to those with hemoglobin AA. These findings highlight the need for comprehensive research, including confirming the study results in other longitudinal sickle cell trait population-level studies and investigation into underlying causes of death, to inform clinical management and counseling for individuals with SCT.

Progression of antenatal preeclampsia in the postpartum period (clinical cases)

Background. Preeclampsia is recognized as one of the leading causes of maternal morbidity and mortality. In the majority of observations in the postpartum period, symptoms of preeclampsia appear in patients with antenatal hypertensive complications. These symptoms appear within the first 710 days after delivery and are accompanied by high blood pressure (BP) and neurologic symptoms, commonly presenting as headaches. According to the literature, common risk factors for the progression of preeclampsia in the postpartum period include maternal age over 3540 years, obesity, cesarean section delivery, and non-Hispanic black race. Patients with progression of antenatal preeclampsia in the postpartum period often require readmission after discharge from the hospital.&#x0D; Description of clinical cases. The first clinical observation involves a 25-year-old female patient was transferred to the cardiology department of the hospital on the fourth day after her first spontaneous labor due to a significant increase in BP combined with complaints of intense headache, nausea, and itching of the palms. Progression of antenatal preeclampsia complicated by the cholestasis was detected. The implementation of a complex treatment led to the normalization of clinical and laboratory parameters. In the second clinical observation, a 31-year-old first-pregnant patient at the gestational age of 27 weeks underwent emergency cesarean section due to the development of eclampsia. The patient developed thrombocytopenia and massive proteinuria a day after delivery for the first time, along with high BP, which was not present during pregnancy. The application of a personalized approach to treatment helped stabilize the maternity patients condition.&#x0D; Conclusion. The presented clinical observations demonstrate the progression of antenatal preeclampsia in the postpartum period. In both cases, disturbances of laboratory parameters, high arterial hypertension, resistant to previously conducted antihypertensive therapy, were noted. Given that preeclampsia is a risk factor for severe complications, patients should not be discharged after delivery until clinical and laboratory parameters have completely normalized.

Short-Term and Long-Term Morbidity after Radical Cystectomy in Patients with NMIBC and Comparison with MIBC: Identifying Risk Factors for Severe Short-Term Complications

Introduction: RC represents a viable treatment option for certain NMIBC patients. However, studies investigating morbidity in the context of RC for NMIBC are scarce. The goal of the current study was to assess and compare morbidity after RC performed in patients with NMIBC and patients with MIBC and to identify risk factors for severe short-term complications. Methods: Medical records of 521 patients who underwent RC for bladder cancer were retrospectively reviewed. Patients were divided into patients with NMIBC and patients with MIBC. The groups were compared and risk factors for severe complications were identified. Results: RC for NMIBC was performed in 123 patients (23.6%). Histological upstaging was seen in 47 NMIBC patients (38.2%) and in 231 MIBC patients (58%, p < 0.001). OS was 29.8% and CSS was 15.5%. Both endpoints were higher for RC for MIBC (p < 0.001). More complications affecting the urinary diversion were seen with RC for NMIBC (p = 0.033) and more continent urinary diversions (p = 0.040) were performed in those patients. Obesity (p = 0.008), a higher ASA score (p = 0.004), and preoperative medical drug anticoagulation (p = 0.025) were risk factors for severe short-term morbidity after both, RC for NMIBC and for MIBC. Conclusion: Patients who underwent RC for NMIBC are exposed to a comparably high perioperative risk than patients with MIBC. RC seems to be a viable treatment option for certain NMIBC patients with a significant histological upstaging in both groups. In patients with obesity, a high ASA score, and with medical drug anticoagulation, the indication for surgery should be confirmed especially strict and possible treatment alternatives should be considered particularly thorough.

Complication After Gastrectomy for Gastric Cancer According to Hospital Volume: Based on Korean Gastric Cancer Association-Led Nationwide Survey Data.

This study aimed to analyze the incidence and risk factors of complications following gastric cancer surgery in Korea and to compare the correlation between hospital complications based on the annual number of gastrectomies performed. A retrospective analysis was conducted using data from 12,244 patients from 64 Korean institutions. Complications were classified using the Clavien-Dindo classification (CDC). Univariate and multivariate analyses were performed to identify the risk factors for severe complications. Postoperative complications occurred in 14% of the patients, severe complications (CDC IIIa or higher) in 4.9%, and postoperative death in 0.2%. The study found that age, stage, American Society of Anesthesiologists (ASA) score, Eastern Cooperative Oncology Group (ECOG) score, hospital stay, approach methods, and extent of gastric resection showed statistically significant differences depending on hospital volumes (P<0.05). In the univariate analysis, patient age, comorbidity, ASA score, ECOG score, approach methods, extent of gastric resection, tumor-node-metastasis (TNM) stage, and hospital volume were significant risk factors for severe complications. However, only age, sex, ASA score, ECOG score, extent of gastric resection, and TNM stage were statistically significant in the multivariate analysis (P<0.05). Hospital volume was not a significant risk factor in the multivariate analysis (P=0.152). Hospital volume was not a significant risk factor for complications after gastric cancer surgery. The differences in the frequencies of complications based on hospital volumes may be attributed to larger hospitals treating patients with younger age, lower ASA scores, better general conditions, and earlier TNM stages.

CT-guided Transthoracic Lung Biopsy: complications and success in yielding a specific diagnosis

Aim: To present risk factors for common complications of CT-guided transthoracic lung biopsy and to analyse the diagnostic success of the procedure in terms of specific diagnostic rates. Materials &amp; Methods: 461 consecutive procedures retrospectively enrolled. Patient, lesion and technical variables are scrutinized in terms of complications and their severity. Pathology results were evaluated for diagnostic specificity. Results: 27% total complications with %17 alveolar haemorrhage, 7% pneumothorax and 3% developed both. ≤ 15 mm size and ≥ 20 mm distance from pleura significantly increases the risk of both PTX and AH. Perilesional emphysema is a predisposing factor of both severe PTX and extended bleeding. Lateral decubitus position increases the likelihood of pneumothorax. Patients with a needle angle of less than 90±15° had an approximate 2-fold increase risk of PTX (P = 0.034). Semi-solid lesions carry a risk of significant bleeding. The accuracy was 96.9% with a specific malignant diagnosis rate of 83% and a specific benign diagnosis rate of 52%. Conclusion: Perilesional emphysema is risk factor of severe complications. Semi-solid lesions are prone to severe bleeding. Lateral decubitus position and low needle angle are important as preventable predisposing factors of PTX. Although the diagnostic yield is satisfactory, the specific benign diagnosis rates are still below expectations and that larger needle biopsies are more beneficial in this regard.

Outcomes of infective endocarditis in patients with and without pericardial effusion: a National Inpatient Sample study

Abstract Introduction Pericardial effusion (PE) in patients with infective endocarditis (IE) has been shown to be an independent risk factor for severe complications, however no significant association with mortality has been established. Our study aims to study the significance of pericardial effusion in patients with IE. Methods We performed a retrospective analysis using the United States National Inpatient Sample (NIS) database to identify all the hospital admissions with IE using ICD 10 codes and divided them into two groups based on the presence of PE. The outcomes of interest were in-hospital mortality, in-hospital complications, need for cardiac surgery, and length of stay (LOS). Results A total of 381,300 patients were hospitalized from 2016 to 2019 with IE, of whom 10,370 developed PE. Mean age of patients in the PE group was 51 years and in non-PE group was 61 years with males and Caucasian race being predominant in both groups. PE group had higher rates of in-hospital death (12.7% vs 9%, P≤0.001) and longer in-hospital stay (12 days vs 7 days, P≤0.001) compared to non-PE group. The rates of cardiac surgery were higher in PE group (26.1% vs 8.4%, P≤0.001). The rates of heart failure, heart block, renal failure, cardiogenic shock, and embolic stroke were higher in PE group [Table 1]. Conclusion Our study shows that presence of PE in patients with IE is a predictor for in-hospital mortality, length of stay, and need for cardiac surgery. Also, these patients are at higher risk for heart failure, heart block, cardiogenic shock and embolic stroke. Funding Acknowledgement Type of funding sources: None.

“Role of kidney function and concentrations of BAFF, sPD-L1 and sCD25 on mortality in hospitalized patients with COVID-19”

BackgroundChronic kidney disease (CKD) is a recognized risk factor for severe complications in COVID-19. Our objective was to analyze the association between kidney function / T and B lymphocyte modulatory factors and risk of mortality in COVID-19 patients.MethodsIn-hospital and 30‐day mortality were analyzed in COVID‐19 patients (n = 110). Plasma levels of selected T and B cell modulators were analyzed and correlated to mortality risk. A subgroup of sex- and eGFR-matched COVID-19 patients was compared to CKD patients without infection and healthy subjects.ResultsCOVID-19 patients who died in hospital and within 30 days had significantly higher BAFF and sCD25 plasma levels than survivors. In logistic regression models patients with high BAFF, sCD25 and sPD-L1 levels had significantly higher risk of both in-hospital and 30-day mortality while there was no association to eGFR. In the subgroup analysis, a higher level of BAFF, IFN-α, sCD25, sPD-L1 and a lower level of sCD40L was observed in COVID-19 patients compared to the CKD group with corresponding kidney function.ConclusionsWe demonstrate that kidney function and concentrations of BAFF, sCD25 and PD-L1, independent of previously recognized risk factors; age, male gender, and leukocytosis are associated with risk of in-hospital and 30-day mortality in patients with COVID-19. These data indicate the significance of adaptive immune system modulators in COVID-19 and motivate further analysis to identify new potential prognostic and therapeutic approaches.

Age and Charlson Comorbidity Index score are not independent risk factors for severe complications after curative esophagectomy for esophageal cancer: a Dutch population-based cohort study

BackgroundThe number of older patients undergoing curative esophagectomy for esophageal cancer is increasing, and minimally invasive techniques are being increasingly used. The aim of this study is to compare postoperative outcomes after curative esophagectomy between older and younger patients. MethodsData was retrieved from the Dutch Upper Gastrointestinal Cancer Audit (DUCA), a national surgical outcome registry. The primary outcome was severe complications, defined as complications graded Clavien-Dindo ≥ 3. The secondary outcomes were postoperative complications, reintervention rates, length of hospital stays, and mortality. Outcomes were compared between patients aged ≥75 and < 75 years. We performed additional subgroup analyses between these age groups after totally minimally invasive esophagectomy (TMIE) and in patients with severe complications. We adjusted for the following parameters: gender, BMI, Charlson Comorbidity Index score (CCI), ASA score, histology, type of neoadjuvant therapy, and surgical technique. ResultsOf all 3775 included patients, 455 (12.1%) were aged ≥75 years and 3302 (87.9%) were aged <75 years. Overall, severe complications occurred in 184 (40.4%) older and in 1140 (34.5%) younger patients (CI = 1.009–1.080). After TMIE, severe complications occurred in 150 (42.1%) older and in 891 (35.8%) younger patients (CI = 1.007–1.088). In patients with severe complications, rates of complications, reinterventions, mortality, and ICU stays were comparable between older and younger patients. After adjustment for casemix, age and CCI score were not independent risk factors for (severe) complications and mortality. ConclusionsAge and Charlson Comorbidity Index are not adequate predictors of postoperative morbidity and mortality after curative esophagectomy for esophageal cancer.

Postoperative Dehydration Is Associated with Frailty and Decreased Survival in Older Patients with Hip Fracture.

Background: Hyperosmolar dehydration (HD) is a risk factor for severe complications in hip fracture in older patients. However, evidence for recommending screening of dehydration is insufficient and its relation with frailty and mortality is unclear. We tested the hypothesis that postoperative HD is associated with frailty and increased mortality. Methods: We recruited 625 older (>65 years) patients surgically treated for hip fracture and co-managed by an orthogeriatric team over one year in 2017. Pre- and postoperative HD (serum osmolarity > 300 mmol/L) was diagnosed. Frailty and associated mortality risk were assessed by the Multidimensional Prognostic Index (MPI). Results: The prevalence of preoperative HD was 20.4%. Compared with no-HD, MPI was similar in HD patients despite higher (p < 0.05) prevalence of polypharmacy, arterial hypertension, diabetes, chronic kidney disease and heart failure. After surgery the incidence of HD decreased to 16.5%, but increased (p = 0.003) in the MPI high-risk subgroup. Postoperative HD was associated with more complications and was an independent determinant of adjusted hospital length of stay (LOS) and of 60- to 365-days mortality. Conclusions: Older frail patients with hip fracture are prone to developing postoperative HD, which independently predicts prolonged hospital LOS and mortality. Systematically screening older patients for frailty and dehydration is advisable to customize hydration management in high-risk individuals.

Evaluation of the risk factors for severe complications and surgery of intestinal foreign bodies in adults: a single-center experience with 180 cases.

BackgroundForeign bodies (FBs) lodged in the intestine or causing intestinal complications are uncommon in clinical practice but may pose diagnostic difficulties and prove life-threatening. This study aimed to evaluate the risk factors for severe complications and surgery to aid clinicians in the diagnosis and management of intestinal FBs.MethodsWe performed a retrospective analysis of patients in whom FBs were lodged in the intestine or caused complications from 2010 to 2020 in the First Affiliated Hospital of Wenzhou Medical University (Zhejiang, China). The characteristics of the patients and FBs, symptoms, imaging findings, diagnostics, treatment strategies, and clinical outcomes were analysed. Furthermore, the risk factors for complications and surgery were investigated.ResultsIn total, 180 patients were included in our study. Most patients (76.1%) were unable to provide a history of ingestion. Bezoars were the most common FBs (35.6%). The FBs were mainly located in the duodenum (32.8%) and the ileum (27.8%). Surgical removal of FBs was successful in 89 (49.4%) patients and endoscopic removal in 54 (30.0%) patients. Eleven with perforations were treated conservatively. FBs located in the jejunum or ileum were more likely to cause severe complications than those located in the duodenum. FBs located in the jejunum, ileum, or sigmoid colon were more likely to undergo surgery, and severe complications were an independent risk factor for surgery.ConclusionIntestinal FBs, often localized in angulation, are likely to be misdiagnosed because most patients do not provide a history of FB ingestion. Surgery and endoscopic therapy are the most commonly used treatment modalities. Surgery is not mandatory in clinically stable patients with small and contained perforations. FBs located in the jejunum or ileum are risk factors for both complications and surgery.

One year follow-up of ablation procedures performed in a single-center over a 32-months period

Arrhythmia ablation procedures are in constant increase. Securing these invasive procedures is one of the major concerns. Complications are relatively rare but can be potentially severe. To describe early and mid-term (one month) complications and the long-term impact on symptoms and antiarrhythmic and anticoagulant agents prescription in a cohort of successive patients who underwent arrhythmia ablation in the department of cardiology of the university hospital of Brest. All patients undergoing interventional arrhythmia procedures are included and followed in the PRINT registry. We included 841 consecutive patients who underwent an arrhythmia ablation procedure between 2017 and 2019, and observed complications (occurring early during or after the procedure and at one month follow-up), symptoms at 3 months and 1 year follow-up, and medication at 1 year. The rate of severe complications was 6.8% with differences according to the type of procedure. The most frequent were vascular complications (2.8% in all patients), conductive disturbances (0.9%), and severe pericardial effusion without need for surgery (1.1% in all procedures, 2.7% in atrial fibrillation ablation, more often in case of radiofrequency ablation). Hypertension and left bundle branch block were independent risk factors for severe complications in our study. The rate of procedure-related death was very low (0.1%). Symptoms, including palpitations and dyspnea were significantly reduced at 1 year. The use of anticoagulant and antiarrhythmic therapy was significantly lower at 1 year. The complication rates in our study were similar, for equivalent procedures, to those reported in other series. In our population, we confirm the favorable impact of ablation procedures on symptoms and quality of life, with a significant decrease in the number of symptomatic patients and the discontinuation or reduction of drug treatment.

Analysis of Clinicopathological Features and Risk Factors for Severe Complications after Gastrectomy for Gastric Cancer in Elderly Patients

Objective: As life expectancy is increasing, the number and proportion of elderly patients with gastric cancer are also expanded. This study aimed to investigate the clinicopathological features for elderly gastric cancer patients undergoing gastrectomy and analyze risk factors for developing severe complications.Methods: A total of 514 patients treated surgically for gastric cancer between January 2016 and December 2019 were enrolled in this retrospective study. Patients were divided into two groups: younger group ( ≤ 69 years) and elderly group ( ≥ 70 years). Clinicopathological characteristics and operative outcomes including the complications and mortality were compared between two groups. Risk factors for severe complications in elderly gastric cancer patients were also investigated.Results: Of the 514 patients, 145 (28.2%) were elderly group. Comorbidity (P &lt; 0.001), differentiated histology (P = -0.006), deeper in tumor depth (P = 0.012), and frequent lymph node metastasis (P = 0.028) were observed in elderly group. Overall complications (P = 0.046) and severe complications (P = 0.049) were significantly higher in elderly group. Multivariate analysis indicated that extent of resection (P = 0.044) was associated with severe complications in elderly gastric cancer patients.Conclusion: Elderly patients have a significantly higher probability of complications and severe complications than younger patients after gastrectomy for gastric cancer. Especially, when total gastrectomy was performed in elderly gastric cancer patients, the risk of developing serious complications was significantly higher more than 3 times. Therefore, surgeons should pay attention to gastric cancer patients over the age of 70 who require total gastrectomy.

Postoperative complications after robotic resection of colorectal cancer: An analysis based on 5-year experience at a large-scale center.

BACKGROUNDAs a common gastrointestinal malignancy, colorectal cancer (CRC) poses a serious health threat globally. Robotic surgery is one of the future trends in surgical treatment of CRC. Robotic surgery has several technical advantages over laparoscopic surgery, including 3D visualization, elimination of the fulcrum effect, and better ergonomic positioning, which together lead to better surgical outcomes and faster recovery. However, analysis of independent factors of postoperative complications after robotic surgery is still insufficient.AIMTo analyze the incidence and risk factors for postoperative complications after robotic surgery in patients with CRC.METHODSIn total, 1040 patients who had undergone robotic surgical resection for CRC between May 2015 and May 2020 were analyzed retrospectively. Postoperative complications were categorized according to the Clavien-Dindo (C-D) classification, and possible risk factors were evaluated.RESULTSAmong 1040 patients who had undergone robotic surgery for CRC, the overall, severe, local, and systemic complication rates were 12.2%, 2.4%, 8.8%, and 3.5%, respectively. Multivariate analysis revealed that multiple organ resection (P < 0.001) and level III American Society of Anesthesiologists (ASA) score (P = 0.006) were independent risk factors for overall complications. Multivariate analysis identified multiple organ resection (P < 0.001) and comorbidities (P = 0.029) as independent risk factors for severe complications (C-D grade III or higher). Regarding local complications, multiple organ resection (P = 0.002) and multiple bowel resection (P = 0.027) were independent risk factors. Multiple organ resection (P < 0.001) and level III ASA score (P = 0.007) were independent risk factors for systemic complications. Additionally, sigmoid colectomy had a lower incidence of overall complications (6.4%; P = 0.006) and local complications (4.7%; P = 0.028) than other types of colorectal surgery.CONCLUSIONMultiple organ resection, level III ASA score, comorbidities, and multiple bowel resection were risk factors for postoperative complications, with multiple organ resection being the most likely.

Use of the modified Clavien‑Dindo classification to determine the risk factors for early complications following radical gastrectomy and the effect of such complications on long‑term prognosis

Surgical resection remains the gold standard treatment for gastric cancer; however, the rate of post‑operative complications remains unsatisfactory. Although the majority of complications are treatable, it remains unknown whether the long‑term survival of patients is affected and what type of complications affect prognosis. In the present study, the modified Clavien‑Dindo classification system was used to examine the incidence of early complications along with the related risk factors following radical gastrectomy (RG) and to determine the effects of such complications on long‑term prognosis. For this purpose, 525 gastric cancer patients with RG were analyzed retrospectively. The results revealed that age [odds ratio (OR), 1.781; P=0.013], pre‑operative comorbidity (OR, 1.765; P=0.020), blood loss (OR, 2.153; P=0.001) and the type of surgery (OR, 3.137; P&lt;0.001) were identified as independent risk factors associated with post‑surgery complications. Blood loss (OR, 13.053; P=0.013) and the resection type (OR, 7.936; P=0.047) were identified as independent risk factors for severe complications. The 5‑year overall survival (OS) rate of patients in the severe complication group was 35%, which was significantly worse than that of patients in the non‑severe complication group (61.8%). Severe complications (hazard ratio, 1.595; P=0.107) were not found to be independent risk factors associated with the 5‑year OS. On the whole, the present study demonstrates that complications following RG were significantly related to age, pre‑operative comorbidity, blood loss and the type of surgery. Severe complications were distinctly affected by blood loss and the resection type. The 5‑year OS of patients in the severe complication group was significantly worse than that of patients in the non‑severe complication group; however, severe complications were not found to be independent risk factors associated with long‑term survival.

Effect of preoperative asymptomatic renal dysfunction on the clinical course after colectomy for colon cancer.

To evaluate the effect of mild renal dysfunction on the clinical course after colectomy in patients with colon cancer. The subjects of this retrospective study were 263 patients who underwent surgical resection for colon cancer at our hospital between 2011 and 2015. Renal function was assessed based on preoperative estimated glomerular filtration rate (eGFR) values. Patients were divided into groups based on their eGFR value of 55ml/min/1.73 m2. The Mann-Whitney U test, chi-square or Fisher exact test, and log-rank test were used in the data analysis. There were 59 patients (22.4%) in the low eGFR group and 204 patients in the normal eGFR group. There were differences between the groups in age, comorbidities, and the levels of hemoglobin, albumin, and serum creatinine. The overall postoperative complication rate, frequency of severe complications, and length of stay were significantly higher in the low eGFR group than in the normal eGFR group. Multivariate analysis revealed that low eGFR was the only independent risk factor for severe complications (Clavien-Dindo classification III/IV). There were no differences in survival between the groups. Preoperative asymptomatic renal dysfunction may be correlated with the development of postoperative complications and a possible significant risk factor for severe complications after colon cancer surgery.
