Impact of estradiol, testosterone and their ratio on left and right auricular myofilament function in male and female patients undergoing coronary artery bypass grafting.

BACKGROUND: The impact of sex hormones on right and left auricular contractile apparatus function is largely unknown. We evaluated the impact of sex hormones on left and right heart contractility at the level of myocardial filaments harvested from left and right auricles during elective coronary artery bypass surgery. METHODS: 150 patients (132 male; 18 female) were enrolled. Preoperative testosterone and estradiol levels were measured with Immunoassay. Calcium induced force measurements were performed with left- and right auricular myofilaments in a skinned fiber model. Correlation analysis was used for comparison of force values and levels of sex hormones and their ratio. RESULTS: Low testosterone was associated with higher top force values in right-sided myofilaments but not in left-sided myofilaments for both sexes (p = 0.000 in males, p = 0.001 in females). Low estradiol levels were associated with higher top force values in right-sided myofilaments (p 0.000) in females and only borderline significantly associated with higher top force values in males (p 0.056). In females, low estradiol levels correlated with higher top force values in left sided myofilaments (p 0.000). In males, higher Estradiol/Testosterone ratio (E/T ratio) was only associated with higher top force values from right auricular myofilaments (p 0.04) In contrast, in females higher E/T ratio was associated with lower right auricular myofilament top force values (p 0.03) and higher top force values in left-sided myofilaments (p 0.000). CONCLUSIONS: This study shows that patients' comorbidities influence left and right sided contractility and may blur results concerning influence of sex hormones if not eliminated. A sex hormone dependent influence is obvious with different effects on the left and right ventricle. The E/T ratio and its impact on myofilament top force showed divergent results between genders, and may partially explain gender differences in patients with cardiovascular disease.

Early standardized clinical judgement for syncope diagnosis in the emergency department.

BACKGROUND: The diagnosis of cardiac syncope remains a challenge in the emergency department (ED). OBJECTIVE: Assessing the diagnostic accuracy of the early standardized clinical judgement (ESCJ) including a standardized syncope-specific case report form (CRF) in comparison with a recommended multivariable diagnostic score. METHODS: In a prospective international observational multicentre study, diagnostic accuracy for cardiac syncope of ESCJ by the ED physician amongst patients ≥ 40 years presenting with syncope to the ED was directly compared with that of the Evaluation of Guidelines in Syncope Study (EGSYS) diagnostic score. Cardiac syncope was centrally adjudicated independently of the ESCJ or conducted workup by two ED specialists based on all information available up to 1-year follow-up. Secondary aims included direct comparison with high-sensitivity cardiac troponin I (hs-cTnI) and B-type natriuretic peptide (BNP) concentrations and a Lasso regression to identify variables contributing most to ESCJ. RESULTS: Cardiac syncope was adjudicated in 252/1494 patients (15.2%). The diagnostic accuracy of ESCJ for cardiac syncope as quantified by the area under the curve (AUC) was 0.87 (95% CI: 0.84-0.89), and higher compared with the EGSYS diagnostic score (0.73 (95% CI: 0.70-0.76)), hs-cTnI (0.77 (95% CI: 0.73-0.80)) and BNP (0.77 (95% CI: 0.74-0.80)), all P < 0.001. Both biomarkers (alone or in combination) on top of the ESCJ significantly improved diagnostic accuracy. CONCLUSION: ESCJ including a standardized syncope-specific CRF has very high diagnostic accuracy and outperforms the EGSYS score, hs-cTnI and BNP.

Clinically inapparent right heart dysfunction is associated with reduced myofilament force development in coronary artery disease.

BACKGROUND: Right ventricular dysfunction after CABG is associated with poor peri- and postoperative outcomes. We aimed to identify clinical and experimental predictors for preoperative inapparent right ventricular dysfunction and therefore hypothesized that reduced myofilament force development as well as altered levels of biomarkers might predict inapparent right ventricular dysfunction. METHODS: From 08/2016 to 02/2018, 218 patients scheduled for CABG were divided into two groups (TAPSE ≥ 20 mm, n = 178; TAPSE < 20 mm, n = 40). Baseline serum samples for biomarkers (Galectin, TGFß1, N Acyl-SDMA, Arginine, ADMA and Pentraxin-3), clinical laboratory and transthoracic echocardiographic parameters were evaluated. To examine the myocardial apparatus of the right ventricle intraoperative right auricular tissue was harvested for stepwise skinned fiber force measurements. RESULTS: Patients with TAPSE < 20 mm had a higher incidence of DM (55 vs. 34%, p = 0.018), preoperative AFib (43 vs. 16%, p < 0.001), reduced GFR (67 ± 18 vs. 77 ± 24 ml/min/1.73 m2, p = 0.013), larger LA area (22 ± 6 vs. 20 ± 5 cm2, p = 0.005) and reduced LVEF (50 vs. 55%, p = 0.008). Furthermore, higher serum ADMA (0.70 ± 0.13 vs. 0.65 ± 0.15 µmol/l, p = 0.046) and higher serum Pentraxin-3 levels (3371 ± 1068 vs. 2681 ± 1353 pg/dl, p = 0.004) were observed in these patients. Skinned fiber force measurements showed significant lower values at almost every step of calcium concentration (pCa 4.52 to pCa 5.5, p < 0.01 and pCa 5.75-6.0, p < 0.05). Multivariable analysis revealed DM (OR 2.53, CI 1.12-5.73, Euro Score II (OR 1.34, CI 1.02-1.78), preoperative AF (OR 4.86, CI 2.06-11.47), GFR (OR 7.72, CI 1.87-31.96), albumin (OR 1.56, CI 0.52-2.60), Pentraxin-3 (OR 19.68, CI 14.13-25.24), depressed LVEF (OR 8.61, CI 6.37-10.86), lower force values: (pCa 5.4; OR 2.34, CI 0.40-4.29 and pCa 5.2; OR 2.00, CI 0.39-3.60) as predictors for clinical inapparent right heart dysfunction. CONCLUSIONS: These preliminary data showed that inapparent right heart dysfunction in CAD is already associated with reduced force development of the contractile apparatus.

Right sided colorectal cancer increases with age and screening should be tailored to reflect this: a national cancer database study.

BACKGROUND: In the United States, colorectal cancer (CRC) screening and surveillance is recommended until age 75. However, rates of surgery for CRC are greatest in the elderly, questioning current guidelines. Tumor sidedness is an emerging prognostic marker that may help guide screening and treatment decisions, with specific benefit evaluating CRC anatomic distribution in the elderly. Our objective was to investigate the anatomical distribution of CRC in the elderly and factors associated with right-sidedness. METHODS: The National Cancer Database (2004-2016) was used to identify elderly patients with CRC. Cases were stratified by tumor sidedness and elderly subgroups: 65-74, 75-84, and ≥ 85 years of age, and further categorized by primary site. Multivariate analysis identified factors associated with CRC right-sidedness. The outcomes were CRC sidedness in the elderly, the anatomic distribution by age group, and factors associated with right-sidedness. RESULTS: There were 508,219 colorectal cancer patients aged over 65 years identified, 54% of whom had a right-sided cancer. The right-sided incidence rates by age group were 49% (65-74 years), 58.2% (75-84 years), and 65.9% (≥ 85 years) (p < 0.001). Variables associated with right-sidedness were age (OR 1.032; 95% CI 1.031-1.033; p < 0.001), female sex (OR 1.541; 95% CI 1.522-1.561; p < 0.001), Medicare (OR 1.023, 95% CI 1.003-1.043; p = 0.027), year of diagnosis ≥ 2010 (OR 1.133; 95% CI 1.119-1.147; p < 0.001), tumor size > 5 cm (OR 1.474; 95% CI 1.453-1.495; p < 0.001), pathologic stage IV (OR 1.036; 95% CI 1.012-1.060; p = 0.003). CONCLUSIONS: We found higher rates of right-sided colon cancer in the 75 and above age group. This is a population who would benefit greatly from a high-quality and complete colonoscopy for early diagnosis. As screening and surveillance for this age group are not currently recommended, our findings question the lack of universal recommendation of colonoscopy in patients over 75 years old. Guidelines for CRC screening and surveillance should consider the colon cancer right-shift in the elderly population. Based on these results, we recommend thorough assessment of the proximal colon in the elderly.

Frailty in older patients undergoing emergency colorectal surgery: USA National Surgical Quality Improvement Program analysis.

BACKGROUND: Frailty is associated with advancing age and may result in adverse postoperative outcomes. A suspected growing elderly population needing emergency colorectal surgery stimulated this study of the prevalence and impact of frailty. METHODS: Elderly patients (defined as aged at least 65 years by Medicare and the United States Census Bureau) who underwent emergency colorectal resection between 2012 and 2016 were identified from the American College of Surgeons National Surgical Quality Improvement Program population database. The five-item modified frailty index (mFI-5) score was calculated, and patients stratified into groups 0, 1 or 2 + . Main outcome measures were the prevalence of frailty, and its impact on 30-day postoperative morbidity, mortality, reoperation, duration of hospital stay (LOS), discharge destination and readmission. RESULTS: A total of 10 025 patients were identified with a median age 75 years, of whom 41·8 per cent were men. The majority (87·7 per cent) had an ASA fitness grade of III or greater and 3129 (31·2 per cent) were frail (mFI-5 group 2+). Major morbidity occurred in one-third of patients and the postoperative mortality rate was 15·9 per cent. Some 52·0 per cent of patients had a prolonged hospital stay and 11·0 per cent were readmitted. Although most patients (88·0 per cent) lived independently before surgery, only 45·4 per cent were discharged home directly. Frailty (mFI-5 2+) predicted mortality, overall and major morbidity, reoperation, prolonged LOS, discharge to an institution and readmission, but frailty was independent of sex. CONCLUSION: Frailty is associated with morbidity, mortality and loss of independence in elderly patients needing emergency colorectal surgery.

ANTECEDENTES: la fragilidad se asocia con la edad avanzada y puede ocasionar resultados adversos postoperatorios. Un presunto aumento de la población mayor que necesita cirugía colorrectal urgente fue el motivo de efectuar este estudio sobre la prevalencia e impacto de la fragilidad. MÉTODOS: Pacientes mayores (definidos como ≥ 65 años por Medicare y la Oficina del Censo de los Estados Unidos) sometidos a resección colorrectal de urgencia fueron identificados a partir de la base de datos poblacional del ACS-NSQIP desde 2012 a 2016. Se calculó el índice de fragilidad modificado de 5 factores (5-factor modified frailty index, mFI-5), y los pacientes se estratificaron en grupos de 0, 1, y 2+. Las medidas de los resultados principales fueron la prevalencia y el impacto de la fragilidad en la morbilidad postoperatoria a los 30 días, mortalidad, reoperación, duración de la estancia hospitalaria (length of stay, LOS), destino al alta y reingreso. RESULTADOS: De 10.131 pacientes, 31,2% (n = 3.129) eran frágiles/mFI-5 de 2+ con una mediana de edad de 75 años y 41,8% eran varones. La mayoría tenían una puntuación ASA 3 o mayor (n = 87,7%), aparecieron complicaciones mayores en un tercio de los pacientes y la mortalidad postoperatoria fue del 15,9%. Se observó una LOS prolongada en 52,0% y 11,0% fueron reingresados. Aunque la gran mayoría (88%) vivían de forma independiente antes de la cirugía, solo el 45,4% fueron dados de alta directamente a su domicilio. Un mFI-5 of 2+ predijo mortalidad, morbilidad global y mayor, reoperación, LOS prolongada, alta a una institución, y reingreso, pero la fragilidad fue independiente del género. CONCLUSIÓN: La fragilidad se asoció con morbilidad, mortalidad y pérdida de independencia en pacientes mayores que necesitan cirugía colorrectal de urgencia.

Evaluating the association of the new National Surgical Quality Improvement Program modified 5-factor frailty index with outcomes in elective colorectal surgery.

BACKGROUND: The 5-factor modified frailty index (mFI-5) is a new, NSQIP-based, predictive tool for mortality and postoperative complications. The mFI-5's predictive ability has been validated within the large-scale NSQIP database but applicability in institutional databases has not been investigated. We sought to assess the association between the mFI-5 and morbidity/mortality at the institutional level. METHODS: A divisional database was queried for 2017 elective colorectal resections and an mFI-5 calculated. The main outcome measure was the association and predictive value of the mFI-5 with major morbidity/mortality and minor complications. Univariable analyses were performed via the Cochran-Armitage Test and Cramer's V. Logistic regression evaluated the relationship between the mFI-5 and morbidity/mortality while accounting for demographics and pre-operative risk factors. Receiver operating characteristic (ROC) curves were plotted to visualize the predictive strength for outcomes. RESULTS: Four hundred and twelve patients were analyzed. 8.7% had major morbidity/mortality and 31.6% minor complications. The mFI-5 categorized patients into 0 (n = 335), 1 (n = 58), and 2+ (n = 19) groups. Univariable analysis showed a higher mFI-5 was associated significantly with major morbidity/mortality (P = 0.004), but not minor (P = 0.281). Multivariable logistic regression showed a strong association between an mFI-5 score of 2+ with major complications (Major: OR = 4.616, CI [1.442-14.776], P = 0.010). ROC curves showed the mFI-5 was poor for predicting outcomes and performed better when other risk factors were added to the model. CONCLUSION: The mFI-5 tool has an independent association with major morbidity/mortality in an institutional dataset for elective colorectal surgery, but is not predictive. Its predictive ability is enhanced when other patient-specific risk factors are incorporated.

Predictors of complications from stoma closure in elective colorectal surgery: an assessment from the American College of Surgeons National Surgical Quality Improvement Program (ACSNSQIP).

BACKGROUND: There is significant morbidity after diverting ileostomy closure, so identifying predictors of complications could be of great benefit. The aim of our study was to evaluate the incidence and risk factors for postoperative morbidity after elective ileostomy closure. METHODS: The ACS-NSQIP dataset was evaluated for elective ileostomy closures from 1/1/2015 to 12/31/2016. Demographic characteristics, operative, and postoperative outcomes were evaluated. The primary outcome was 30-day major morbidity (Clavien class III and greater). Secondary outcomes were rates and predictors of major morbidity, superficial site infection (SSI), reoperation, and readmission from multivariate logistic regression modeling. RESULTS: We retrospectively evaluated 1885 patients. The median operative time was 65 (IQR 50-90) minutes and median length of stay was 3 (IQR 2-5) days. Major morbidity was recorded in 6.7%, including mortality (1.0%), deep/organ space SSI (2.6%), dehiscence (0.8%), reintubation (0.5%), sepsis (1.7%), septic shock (0.8%), and reoperation (3.7%). Readmission was recorded in 9.7% and 6.2% had SSI. Multivariate logistic regression showed male sex (OR 1.584; 95% CI 1.068-2.347; p = 0.022) and longer operative time (OR 1.004; 95% CI 1.001-1.007; p = 0.009) were among those variables associated with increased odds of major morbidity. Dyspnea (OR 2.431; 95% CI 1.139-5.094; p = 0.021) and longer operative time (OR 1.003; 95% CI 1.001-1.007; p = 0.034) were among the independent risk factors for SSI. Male sex (OR 2.246; 95% CI 1.297-3.892; p = 0.004, chronic obstructive pulmonary disease (OR 2.959; 95% CI 1.153-7.591; p = 0.024), and longer operative time (OR 1.005; 95% CI 1.001-1.009; p = 0.011) were associated with increased odds of reoperation. Chronic obstructive pulmonary disease (OR 2.578; 95% CI 1.338-4.968; p = 0.005), wound infection (OR 2.680; 95% CI 1.043-6.890; p = 0.041), and inflammatory bowel disease (OR 2.565; 95% CI 1.203-5.463; p = 0.015) were associated with increased odds of readmission. CONCLUSIONS: Elective stoma closure has significant risk of morbidity. Patients with longer operative times were at increased risk for major morbidity, overall SSI, and reoperation. From the analysis, factors specifically associated with major morbidity, overall infectious complications, readmissions, and reoperations were identified. This information can be used to prospectively prepare for these high-risk patients, potentially improving postoperative outcomes.

Restorative surgery for ulcerative colitis in the elderly: an analysis of ileal pouch-anal anastomosis procedures from the American College of Surgeons National Surgical Quality Improvement Program.

BACKGROUND: Ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC) can be performed as either 2- or 3-stage procedure. IPAA in the elderly has been reported as safe and feasible, but little work to date has assessed outcomes by procedure. The aim of our study was to assess use and short-term outcomes of 2- and 3-stage IPAA in older adults. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) Database was searched for ≥ 65-year-old patients who underwent IPAA for UC in 2- or 3-stage from 2012 to 2016. The primary endpoint was the rate and trends of the two approaches over time. Secondary endpoints included 30-day adverse events and complication-associated costs. RESULTS: Overall, 123 patients were included: 77.5% (n = 83) 2-stage and 40 (32.5%) 3-stage IPAA. Mean age was 68.7 ± 3.9 years, with 43 (34.9%) women. The use of the 3-stage IPAA increased over time (18.8% in 2012 vs. 33.3% in 2016), with decreasing use of 2-stage IPAA (81.3% vs. 66.7%, p < 0.001). The morbidity associated with the procedures decreased over time, overall (81.3% in 2012 and 51.5% in 2016, p < 0.001) and in each group individually. No differences were observed in postoperative complications across groups (45.8% 2-stage, 32.5% 3-stage). The overall mean costs of care when no postoperative complications occurred was $25,910, vs. $38,577 when any complication occurred (p < 0.001), but no differences were observed between groups. CONCLUSION: In a national analysis, there was a trend of increasing 3-stage vs. 2-stage IPAA for UC in older Americans. Complications and complication-associated costs were comparable across approaches, suggesting that the choice of procedure type should be based on the specific patient comorbidities and surgeon preferences.

Analysis of the impact of EEA stapler size on risk of anastomotic complications in colorectal anastomosis: does size matter?

BACKGROUND: Colorectal anastomotic complications are dreaded and dramatically affect outcomes. Causes are multifactorial, with the size of the end-to-end anastomosis (EEA) stapler a modifiable factor and potential target for risk reduction. Our goal was to examine the impact of the EEA stapler size on the risk of anastomotic complications in left-sided colorectal resections. METHODS: A prospective divisional database was reviewed for consecutive elective left-sided resections with a colorectal anastomosis using an EEA stapler from January 2013 May 2018 inclusive. Patients were stratified into 25-29 mm or 30-33 mm cohorts. Patient and disease demographics, operative variables, and postoperative outcomes were evaluated. The main outcome measures were the rate and factors associated with anastomotic complications. RESULTS: Four hundred seventy-three cases were evaluated, 185 ( 39.1%) were in the 25-29 mm group and 288 (60.9%) in the 30-33 mm group. Patients were comparable in demographics and operative variables. More males were anastomosed with the 30-33 mm than with the 25-29 mm stapler (57.6% vs 28.6%, p < 0.01). Significantly more patients developed an anastomotic stricture with the 25-29 mm than with the 30-33 mm staplers (7.1% vs. 2.1%; p = 0.007). There was no significant difference in leak rates or reoperation/interventions between groups. On logistic regression, neither gender, operative indication nor approach were associated with anastomotic leak, readmission, or reoperation/intervention. Stapler size remained significantly associated with stricture (p = 0.032). CONCLUSIONS: The 25-29 mm EEA staplers were associated with an increased rate of anastomotic stricture compared to 30-33 mm staplers in left-sided colorectal anastomoses. As stapler size is a simple process measure that is easily modifyable, this is a potential target for improving anastomotic complication rates. Further controlled trials may help assess the impact of stapler size on improving patient and quality outcomes.

Serological biomarker profiles of rapidly progressive osteoarthritis in tanezumab-treated patients.

There is a need for efficacious and safe pain treatments for OA (osteoarthritis). The nerve growth factor (NGF) antibody tanezumab is associated with high efficacy, but when combined with chronic NSAID treatment shows an increased risk of rapidly progressive osteoarthritis (RPOA) in a small group of patients. AIM: The aim of this study was to phenotype with biochemical biomarkers of bone, cartilage, soft tissue, synovial metabolism OA patients who are at risk of developing RPOA type-2, for both limited and chronic NSAIDs users. MATERIAL AND METHODS: The dataset consisted of OA patients participating in tanezumab trials who used NSAIDs <90 days (limited NSAID users) or chronic users (NSAIDs ≥90 days) over an average 10 month period. Biomarker data were available for 47 cases (RPOA type-2) and 92 controls. Non-linear and linear multivariable predictive models were developed. RESULTS: By use of two biomarkers at baseline the receiver operating characteristic (ROC) curve area for RPOA type-2 in limited NSAID users was 71%, [CI] (60-83%). OA subjects with this biomarker phenotype had 8-fold higher confidence interval [CI][(2-33)] relative risk of developing RPOA type-2 as compared to OA patients without this phenotype. The AUC of the model in chronic NSAIDs users based on 5 biomarkers was 78%, [CI](69-88%), with 4-fold [CI (2-6)] relative risk of developing RPOA type-2. CONCLUSION: In this hypothesis generating and exploratory study, we identified combinations of biomarkers associated with OA patients who develop RPOA type-2, which may be related to the pathology of the RPOA type-2 joint.

A National study on the adoption of laparoscopic colorectal surgery in the elderly population: current state and value proposition.

BACKGROUND: The economic and clinical benefits of laparoscopic colorectal surgery are proven, yet may be underutilized in appropriate cases, especially in the elderly. Since the elderly constitute the greatest colorectal surgical volume, our goal was to identify trends in utilization and impact of laparoscopy in this cohort. METHODS: A national review of elective inpatient colorectal resections from the Premier Inpatient Database between 2010 and 2015 was performed. Patients were included if elderly (≥ 65 years), then grouped into open or laparoscopic procedures. The main outcome measures were trends in utilization by approach and total costs for the episode of care, length of stay (LOS), readmission, and complications by approach in the elderly. Multivariable regression models controlled for differences across platforms, adjusting for patient demographic, comorbidities and hospital characteristics. RESULTS: In 70,655 elderly patients evaluated, laparoscopic adoption remained lower than open throughout the study period. Rates increased until 2013, then declined, with increasing rates of open surgery. Laparoscopy was associated with significantly lower mean total costs ($4012 less/case), complications and readmissions (36% and 33% less, respectively), and shorter LOS (2.6 less days) than open cases (all p < 0.0001). When complications occurred, they were less severe and the readmission episodes were less costly with laparoscopy than open colorectal surgery. CONCLUSION: The adoption of laparoscopy in the elderly has lagged behind open surgery and even declined in recent years despite being associated with improved clinical outcomes and reduced cost. With this tremendous value proposition to increase use of laparoscopic surgery in the elderly, further work needs to evaluate root causes of the disparity.

Colorectal cancer in inflammatory bowel disease: review of the evidence.

Inflammatory bowel disease (IBD)-related colorectal cancer (CRC) is responsible for approximately 2% of the annual mortality from CRC overall, but 10-15% of the annual deaths in IBD patients. IBD-related CRC patients are also affected at a younger age than sporadic CRC patients, and have a 5-year survival rate of 50%. Despite optimal medical treatment, the chronic inflammatory state inherent in IBD increases the risk for high-grade dysplasia and CRC, with additional input from genetic and environmental risk factors and the microbiome. Recognizing risk factors, implementing appropriate surveillance, and identifying high-risk patients are key to managing the CRC risk in IBD patients. Chemoprevention strategies exist, and studies evaluating their efficacy are underway. Once dysplasia or invasive cancer is diagnosed, appropriate surgical resection and postoperative treatment and surveillance are necessary. Here, we discuss the current state of IBD-related CRC, prevalence, risk factors, and evidence for surveillance, prophylaxis, and treatment recommendations.
