Background: Pulmonary complications remain relatively high in morbidities that arise after liver surgery and are associated with increased length of hospital stay and higher cost. Identification of possible risk factors in this retrospective analysis may help reduce operative morbidity and achieve better outcomes. Methods: In all, 363 consecutive patients underwent elective hepatectomies between July 2008 and November 2013 and these were identified and analyzed retrospectively. Patient demographics and perioperative variables were collected. The main outcome was an analysis of risk factors associated with postoperative pleural effusion (PPE). Results: Of 363 patients receiving hepatectomies, 80 patients (22.0%) developed pulmonary complications. The predominant pulmonary complication in this series is pleural effusion (76 patients, 95%). Univariate analysis found that older age, higher body mass index (BMI), chronic obstructive lung disease, asthma, heart disease, hepatitis C infection, heavy smoking, American Society of Anesthesiology class III and IV, hepatectomy site, combined surgeries, perioperative blood transfusion, and cirrhosis of liver were associated with PPE. Only older age, higher BMI, asthma, heavy smoker, combined gastrointestinal surgeries, and perioperative blood transfusion were identified as independent risk factors in multivariate analysis. Conclusion: This study identifies 6 risk factors for PPE. Identification and management of some of these factors could possibly reduce morbidity and improve short-term surgical outcomes.

Purpose.Postoperative pulmonary complications (PPCs) are common after major surgeries. However, the number of studies regarding PPCs following total knee arthroplasty (TKA) is limited. The aim of this study was to determine the incidence of early PPCs following TKA by computed tomography (CT) scan and to identify associated risk factors.Methods.Patients, who were diagnosed with osteoarthritis or rheumatoid arthritis and underwent primary TKA at our institution, were included in this prospective cohort study. Patients received a standard procedure of TKA under general anesthesia. Chest CT scan was performed during 5–7 days postoperatively. Univariate analysis and multivariate logistic regression analysis were employed to identify the risk factors.Results.The total incidence of early PPCs following TKA was 45.9%. Rates of pneumonia, pleural effusion, and atelectasis were 14.4%, 38.7%, and 12.6%, respectively. Lower body mass index and perioperative blood transfusion were independent risk factors for PPCs as a whole and associated with atelectasis. Postoperative acute episode of hypoxemia increased the risk of pneumonia. Blood transfusion alone was related to pleural effusion.Conclusions.The incidence of early PPCs following TKA was high. For patients with relevant risk factors, positive measures should be adopted to prevent PPCs.

Aims: In the setting of rising healthcare costs, more cost efficiency in total hip arthroplasty (THA) is required. Following THA, most patients are monitored with serial hemoglobin testing despite few needing blood transfusions.  This testing adds cost and may not be necessary in most patients.  This study aims to identify factors associated with transfusion, therefore guiding hemoglobin monitoring following THA.Patients and Methods: Patients who underwent primary THA in 2015 were identified using the National Surgical Quality Improvement Project (NSQIP) database.  Patient discharged on the day of surgery were excluded. Patients were classified into those receiving transfusion versus no transfusion. Demographics and comorbidities were compared between groups followed by univariate and multivariate analysis, allowing identification of patient characteristics and comorbidities associated with transfusion. Results: Overall, 28664 patients who underwent THA patients were identified.  Within this group, 6.1% (n=1737) had a post-operative transfusion.  Patients receiving a blood transfusion were older, had lower body mass index, and had higher rates of chronic obstructive pulmonary disease (COPD), heart failure, dialysis, prior transfusion, and were more frequently ASA class 3-4 (p<0.001).  Univariate analysis demonstrated that patients requiring transfusion had higher complication rates (4.3% vs. 12.8%, p<0.0001).  Multivariate analysis identified age >70, diabetes, smoking, COPD, prior transfusion, and operative time >2 hours as independent risk factors for transfusion.Conclusion: Among THA patients, characteristics and comorbidities exist that are associated with increased likelihood of transfusion.  Presence of these factors should guide hemoglobin monitoring post-operatively. Selective hemoglobin monitoring can potentially decrease the cost of THA.

AbstractTo evaluate potential factors associated with the risk of perioperative blood transfusion (PBT) with implications on length of hospital stay (LOHS) and major post-operative complications in patients who underwent robot-assisted radical prostatectomy (RARP) as a primary treatment for prostate cancer (PCa). In a period ranging from January 2013 to August 2019, 980 consecutive patients who underwent RARP were retrospectively evaluated. Clinical factors such as intraoperative blood loss were evaluated. The association of factors with the risk of PBT was investigated by statistical methods. Overall, PBT was necessary in 39 patients (4%) in whom four were intraoperatively. Positive surgical margins, operating time and intraoperative blood loss were associated with perioperative blood transfusion on univariate analysis. On multivariate analysis, the risk of PBT was predicted by intraoperative blood loss (odds ratio, OR 1.002; 95% CI 1.001–1.002; p < 0.0001), which was associated with prolonged operating time and elevated body mass index (BMI). PBT was associated with delayed LOHS and Clavien–Dindo complications > 2. In patients undergoing RARP as a primary treatment for PCa, the risk of PBT represented a rare event that was predicted by severe intraoperative bleeding, which was associated with increased BMI as well as with prolonged operating time. In patients who received a PBT, prolonged LOHS as well as an elevated risk of major Clavien–Dindo complications were seen.

AbstractBackgroundThis study examined the incidence of a person’s first diagnosis of a selected chronic disease, and the relationships between modifiable lifestyle risk factors and age to first of six chronic diseases.MethodsOntario respondents from 2001 to 2010 of the Canadian Community Health Survey were followed up with administrative data until 2014 for congestive heart failure, chronic obstructive respiratory disease, diabetes, lung cancer, myocardial infarction and stroke. By sex, the cumulative incidence function of age to first chronic disease was calculated for the six chronic diseases individually and compositely. The associations between modifiable lifestyle risk factors (alcohol, body mass index, smoking, diet, physical inactivity) and age to first chronic disease were estimated using cause-specific Cox proportional hazards models and Fine-Gray competing risk models.ResultsDiabetes was the most common disease. By age 70.5 years (2015 world life expectancy), 50.9% of females and 58.1% of males had at least one disease and few had a death free of the selected diseases (3.4% females; 5.4% males). Of the lifestyle factors, heavy smoking had the strongest association with the risk of experiencing at least one chronic disease (cause-specific hazard ratio = 3.86; 95% confidence interval = 3.46, 4.31). The lifestyle factors were modelled for each disease separately, and the associations varied by chronic disease and sex.ConclusionsWe found that most individuals will have at least one of the six chronic diseases before dying. This study provides a novel approach using competing risk methods to examine the incidence of chronic diseases relative to the life course and how their incidences are associated with lifestyle behaviours.

IntroductionThere were almost 1 million deaths in children aged between 5 and 14 years in 2017, and pneumonia accounted for 11%. However, there are no validated guidelines for pneumonia management in older children and data to support their development are limited. We sought to understand risk factors for mortality among children aged 5–14 years hospitalised with pneumonia in district-level health facilities in Kenya.MethodsWe did a retrospective cohort study using data collected from an established clinical information network of 13 hospitals. We reviewed records for children aged 5–14 years admitted with pneumonia between 1 March 2014 and 28 February 2018. Individual clinical signs were examined for association with inpatient mortality using logistic regression. We used existing WHO criteria (intended for under 5s) to define levels of severity and examined their performance in identifying those at increased risk of death.Results1832 children were diagnosed with pneumonia and 145 (7.9%) died. Severe pallor was strongly associated with mortality (adjusted OR (aOR) 8.06, 95% CI 4.72 to 13.75) as were reduced consciousness, mild/moderate pallor, central cyanosis and older age (>9 years) (aOR >2). Comorbidities HIV and severe acute malnutrition were also associated with death (aOR 2.31, 95% CI 1.39 to 3.84 and aOR 1.89, 95% CI 1.12 to 3.21, respectively). The presence of clinical characteristics used by WHO to define severe pneumonia was associated with death in univariate analysis (OR 2.69). However, this combination of clinical characteristics was poor in discriminating those at risk of death (sensitivity: 0.56, specificity: 0.68, and area under the curve: 0.62).ConclusionChildren >5 years have high inpatient pneumonia mortality. These findings also suggest that the WHO criteria for classification of severity for children under 5 years do not appear to be a valid tool for risk assessment in this older age group, indicating the urgent need for evidence-based clinical guidelines for this neglected population.

Objectives: The amount of blood transfusion after knee arthroplasty seem to vary in different reported study. We carried out a retrospective study to analysis pre-operative risk factors for blood transfusion in patient whom underwent knee arthroplasty in our institution. Methods: A retrospective study of 190 patients treated with 194 procedure (186 unilateral knee arthroplasty, 4 bilateral knee arthroplasty) from November 2014 to October 2015 was analyzed. A univariate analysis was performed to establish the relationship between all variables and the need for postoperative transfusion. Variables that were determined to have significant relationship were include in a multivariable analysis.. Results: The univariate analysis revealed a significant relationship between need for postoperative blood transfusion and preoperative hemoglobin levels, surgical technique, arthrotomy approach, DVT prophylaxis, operative blood loss, surgical technique and surgeon experience. The multivariate analysis identified a significant relationship between need for transfusion and preoperative hemoglobin level, surgical technique and operative blood loss. Patients with a preoperative hemoglobin less than 12 g/dL had a 5.1 times greater risk of having a transfusion than those with a hemoglobin level ≥ 12 g/dL. The surgical technique with computer assisted surgery had a 0.15 times lesser risk of having a transfusion than those with the conventional technique. Conclusion: The preoperative hemoglobin level < 12 g/dL was shown to increase risk of the need for blood transfusion after knee arthroplasty, while computer assist surgery total knee arthroplasty was shown to decrease risk of blood transfusion. We suggest that patients with preoperative hemoglobin < 12 g/dL need to be crossmatching PRC in pre-operative steps.

ObjectivesOccupational dust exposure may induce various lung diseases, including pneumoconiosis and chronic obstructive pulmonary disease (COPD). The features of combined COPD and pneumoconiosis have not been well described, and this may hamper the management. This study aimed to describe the prevalence and characteristics as well as the risk factors of the combined diseases.DesignA cross-sectional study.Setting and participants758 patients with pneumoconiosis were recruited at a single-medical centre. Of these, 675 patients with pneumoconiosis, including asbestosis, silicosis, coal workers’ pneumoconiosis and other pneumoconiosis, was eligible for analysis.Primary outcome measuresCOPD was diagnosed based on clinical features and/or history of exposure to risk factors and post bronchodilator forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) ratio <0.7. Clinical data were collected from predesigned medical reports. The patients underwent both chest radiograph and high-resolution CT scans. Risk factors for combined COPD and pneumoconiosis were analysed using regression analysis.ResultsCOPD prevalence overall was 32.7% (221/675) and was the highest in silicosis (84/221) and coal workers’ pneumoconiosis (100/221). COPD prevalence increased with smoking pack-years, dust exposure duration and pneumoconiosis stage. Patients with combined diseases had lower body mass index, higher smoking index and worse pulmonary function. Risk factors for combined diseases included heavy smoking, silica or coal exposure and advanced pneumoconiosis. The interaction between dust exposure and smoking in COPD was also identified. The risk of combined COPD significantly increased with heavy smoking and silica or coal exposure (OR 5.49, 95% CI 3.04 to 9.93, p<0.001).ConclusionsCOPD is highly prevalent in patients with pneumoconiosis, especially patients with silicosis and coal workers’ pneumoconiosis. Occupational dust exposure as well as heavy smoking is associated with an increased risk of combined COPD and pneumoconiosis, which demands an effective preventive intervention.

Aortic Valve Reimplantation

Abstract Introduction Aortic valve reimplantation is considered technically demanding. We searched for predictors of long-term outcome including the surgeon as risk factor. Methods We selected all aortic valve reimplantations performed in our department between December 1999 and January 2017 and obtained a complete follow-up. The main indications were combined aortic aneurysm plus aortic valve regurgitation (AR), 69% and aortic dissections (15%). In 14%, valves were bicuspid. Cusp repair was performed in 27% of patients. One-third received additional procedures (coronary artery bypass grafting, mitral, or arch surgery). We performed multivariable analyses for independent risk factors of short- and long-term outcomes, including “surgeon” as variable. Twelve different surgeons operated on 193 patients. We created three groups: surgeons A and B with 84 and 64 procedures, respectively, and surgeon C (10 surgeons for 45 patients). Results Cardiopulmonary bypass and clamp times were 176 ± 45 and 130 ± 24 minutes, respectively. In-hospital mortality was 2%. Postoperatively, 5% had mild and 0.5% had moderate AR. Kaplan–Meier's survival estimates, freedom from reoperation, and freedom from severe AR at 12 years were 97 ± 1, 93 ± 2, and 91 ± 3%, respectively. Age and chronic obstructive pulmonary disease appeared as risk factors for perioperative complications by univariate analysis. Age, coronary artery disease, and duration of cardiopulmonary bypass, but not surgeon, presented as risk factors by multivariable analysis. Conclusion The results suggest that if a David procedure is performed successfully, long-term durability may be excellent. They also suggest that good and durable results are possible even with limited experience of the operating surgeon.
