Socioecological Determinants of Health and the Quality of Colonoscopy in Rural Alabama.

BACKGROUND: Rural patients suffer higher incidence of and mortality from colorectal cancer. Ensuring high-quality screening is essential to address these disparities. OBJECTIVE: To investigate whether socioecological determinants of health are associated with colonoscopy quality in rural Alabama. DESIGN: Retrospective review. SETTING: Data across three rural hospitals in Alabama from August 2021 to July 2023. PATIENTS: We included adults (≥18 years) who underwent screening or diagnostic colonoscopy and completed a validated survey that measures socioecological determinants of health. MAIN OUTCOME MEASURES: Primary outcomes included bowel preparation quality, cecal intubation, and adenoma detection rate. We linked th e survey responses to these quality metrics to identify factors associated with outcomes. Analyses included the χ 2, Fisher's Exact and Kruskal-Wallis Rank sum tests, with p < 0.05 considered statistically significant. RESULTS: The 84 patients surveyed were 66.7% male, 50.0% Black, and had a median age of 64 years. Optimal bowel preparation was present in 88.0%, 89.3% had successful cecal intubations, and overall adenoma detection rate was 45.8%. Patients with suboptimal bowel preparation described lower rates of internet access (60.0% vs. 87.4%, p < 0.05), more difficulty understanding written information (30.0% vs. 1.4%, p < 0.05) and lacked a sense of responsibility for their health (30.0% vs. 51.4%, p < 0.05) compared to those having optimal bowel preparation. Those with unsuccessful cecal intubations had lower physician-trust (55.6% vs. 73.3%, p < 0.05), while patients with successful cecal intubations were more confident in preventing health-related problems (53.3% vs. 33.3%, p < 0.05) and had a more supportive social environment (72.0% vs. 66.7%, p < 0.05). LIMITATIONS: Retrospective design and small sample size limiting multivariable analyses. CONCLUSION: In rural Alabama, health literacy, internet access, and physician-trust were associated with low-quality colonoscopy, while a higher patient sense of responsibility and a supportive social environment was associated with higher-quality metrics. These findings identify potential targets for improving colonoscopy quality in rural settings. See Video Abstract.

Novel Characterization of Socioecological Determinants of Health in Rural Alabama.

INTRODUCTION: Socioecological determinants of health (SEDOHs) influence disparities in surgical outcomes. However, SEDOHs are challenging to measure, limiting our ability to address disparities. Using a validated survey (SEDOH-88), we assessed SEDOHs in three rural communities in Alabama. We hypothesized that SEDOHs would vary significantly across sites but measuring them would be acceptable and feasible. MATERIALS AND METHODS: This was a retrospective review of a prospectively maintained database involving surgical patients who completed the SEDOH-88 and a secondary survey assessing it's acceptability or feasibility from August 2021 to July 2023. Included patients underwent endoscopic, minimally invasive, or open surgery at three rural hospitals: Demopolis (DM), Alexander City (AC), and Greenville (GV). RESULTS: The 107 participants comprised 48 (44.9%) from DM, 27 (25.2%) from AC, and 32 (29.9%) from GV, respectively. The median age was 64 y, and 65.6% were female. When comparing DM to AC and GV by individual factors, DM had the largest Black population (78.7 versus 22.2 versus 48.3%, P < 0.001) and more often required help reading hospital materials (20.5 versus 3.7 versus 10.3%, P = 0.007). When comparing DM to AC and GV by structural and environmental factors, DM had more Medicaid enrollees (27.3 versus 3.7 versus 6.9%, P = 0.033) and lacked fresh produce (18.2 versus 25.9 versus 39.3%, P = 0.033) and internet access (63.6 versus 100.0 versus 86.2%, P < 0.001). The SEDOH-88 had an overall 90.9% positive acceptability and feasibility score. CONCLUSIONS: SEDOHs varied significantly across rural communities regarding individual (race or health literacy), structural (insurance), and environmental-level factors (nutritious food or internet access). The high acceptability and feasibility of the SEDOH-88 shows it's potential utility in identifying targets for future disparity-reducing interventions.

Minimally Invasive Management of Complicated Diverticular Disease: Current Status and Review of Literature.

BACKGROUND: Diverticulitis is a common condition which carries significant morbidity and socioeconomic burden (McGillicuddy et al in Arch Surg 144:1157-1162, 2009). The surgical management of diverticulitis has undergone significant changes in recent years. This article reviews the role of minimally invasive approach in management of complicated diverticulitis, with a focus on recent concepts and advances. MATERIALS AND METHODS: A literature review of past 10 years (January 2004 to September 2014) was performed using the electronic database MEDLINE from PubMed which included articles only in English. RESULTS: We identified total of 139 articles, out of which 50 were excluded resulting in 89 full-text articles for review 16 retrospective studies, 7 prospective cohorts, 1 case-control series and 1 systematic review were included. These suggest that urgent surgery is performed for those with sepsis and diffuse peritonitis or those who fail to improve despite medical therapy and/or percutaneous drainage. In addition, 3 randomized control trials: DILALA, LapLAND and the Scandinavian Diverticulitis trial are working towards evaluating whether laparoscopic lavage is safe in management of complicated diverticular diseases. Growing trend toward conservative or minimally invasive treatment modality even in severe acute diverticulitis was noticed. CONCLUSIONS: Laparoscopic peritoneal lavage has evolved as a good alternative to invasive surgery, yet clear indications for its role in the management of complicated diverticulitis need to be established. Recent evidence suggests that existing guidelines for optimal management of complicated diverticulitis should be updated. Non-resectional radiographic techniques are likely to play a prominent role in the initial treatment of complicated diverticulitis in the near future.

Comparison of percutaneous device closure versus surgical closure of peri-membranous ventricular septal defects: A systematic review and meta-analysis.

BACKGROUND: While percutaneous device closure (PDC) is a first-line therapy for isolated muscular ventricular septal defects (mVSD), surgery is still the preferred approach for peri-membranous ventricular septal defects (pmVSD). OBJECTIVE: We sought to compare the outcomes of percutaneous versus open surgical closure of pmVSDs. METHODS: PubMed, Cochrane Library, and Web of Science databases were searched through October 15, 2014 for English language studies comparing outcomes of PDC with surgical closure of pmVSDs. Study quality, publication bias, and heterogeneity were assessed. A meta-analysis of selected studies was performed using a random effects model. Comparison was done for early (<1 month) safety and efficacy outcomes. RESULTS: Seven studies with a total of 3,134 patients (PDC = 1,312, surgery = 1,822) were identified. Patients in the PDC group were older than those treated surgically (mean age 12.2 vs. 5.5 years, respectively). In six out of seven studies, the mean VSD size was found to be comparable between the treatment arms (PDC 4.9 mm vs. surgery 6.0 mm). Males represented 52% of patients in either group. Follow-up ranged from 5 to 42 months. No significant differences were observed between PDC vs. surgery in terms of procedural success rate [relative risk (RR): 1.00, confidence interval (CI): 0.99-1.00; P = 0.67]. Combined safety end points for major complications (early death/reoperation/permanent pacemaker) were similar in both groups (RR: 0.55, CI: 0.23-1.35; P = 0.19) as were as other outcomes like post-procedure significant residual shunt (RR: 0.69, CI: 0.29-1.68; P = 0.41), significant valvular (aortic/tricuspid) regurgitation (RR: 0.70, CI: 0.26-1.86; P = 0.47), and advanced heart block (RR: 0.99, CI: 0.46-2.14; P = 0.98). The need for blood transfusion (RR: 0.02, CI: 0.00-0.05; P < 0.001) and duration of hospital stay [standard mean difference (SMD) -2.17 days, CI: -3.12 to -1.23; P < 0.001] were significantly reduced in the PDC group. CONCLUSION: Percutaneous closure of pmVSD when performed in a selected subgroup of patients is associated with similar procedural success rate without increased risk of significant valvular regurgitation or heart block when compared with surgical closure.

Efficacy and safety of transulnar coronary angiography and interventions--a single center experience.

OBJECTIVES: To evaluate the efficacy and long-term safety of transulnar approach in complex coronary interventions. BACKGROUND: The success rate of transulnar approach in complex coronary interventions and its long-term safety remains to be proven. METHODS: We conducted a retrospective chart review of patients undergoing transulnar coronary angiography and interventions at our institution from January 2004 through July 2009. Primary endpoint of the study was the success rate of the procedure. Secondary endpoints were major bleeding, local vascular and neurological complications, cerebrovascular accident (CVA)/transient ischemic attack (TIA), myocardial infarction (MI), all-cause mortality, and major adverse cardiovascular events (MACE) rate that was a composite of MI, CVA/TIA, and all-cause mortality. RESULTS: Of 81 patients undergoing transulnar approach, 41 (50.6%) patients underwent intervention on 65 lesions. Twelve percent of the interventions were performed on coronary bypass grafts and 9.2% on the left main coronary artery. Success rates for transulnar access, coronary angiography, and coronary/bypass graft interventions were 93.8%, 100%, and 92.6%, respectively. Follow-up data was available on 71 patients at short term (30 days) and 58 patients at long term (1 year). At 30-day follow-up, vascular complication rate was 2.8 %. At 1-year follow-up, there were no residual deficits from vascular or neurological complications associated with the index procedure and the overall MACE rate was 3.4%. CONCLUSION: In this first study evaluating long-term safety and feasibility of transulnar coronary angiography and complex coronary interventions, we conclude that transulnar approach appears to be safe and effective.

Development and validation of a risk calculator for prediction of cardiac risk after surgery.

BACKGROUND: Perioperative myocardial infarction or cardiac arrest is associated with significant morbidity and mortality. The Revised Cardiac Risk Index is currently the most commonly used cardiac risk stratification tool; however, it has several limitations, one of which is its relatively low discriminative ability. The objective of the present study was to develop and validate a predictive cardiac risk calculator. METHODS AND RESULTS: Patients who underwent surgery were identified from the American College of Surgeons' 2007 National Surgical Quality Improvement Program database, a multicenter (>250 hospitals) prospective database. Of the 211 410 patients, 1371 (0.65%) developed perioperative myocardial infarction or cardiac arrest. On multivariate logistic regression analysis, 5 predictors of perioperative myocardial infarction or cardiac arrest were identified: type of surgery, dependent functional status, abnormal creatinine, American Society of Anesthesiologists' class, and increasing age. The risk model based on the 2007 data set was subsequently validated on the 2008 data set (n=257 385). The model performance was very similar between the 2007 and 2008 data sets, with C statistics (also known as area under the receiver operating characteristic curve) of 0.884 and 0.874, respectively. Application of the Revised Cardiac Risk Index to the 2008 National Surgical Quality Improvement Program data set yielded a relatively lower C statistic (0.747). The risk model was used to develop an interactive risk calculator. CONCLUSIONS: The cardiac risk calculator provides a risk estimate of perioperative myocardial infarction or cardiac arrest and is anticipated to simplify the informed consent process. Its predictive performance surpasses that of the Revised Cardiac Risk Index.

Routine Intraoperative Use of Esophageal Bougie in Minimally Invasive Hiatal Hernia Repair is Not Necessary.

Background: Laparoscopic hiatal hernia repair can be performed with an antireflux procedure. Routine use of an esophageal bougie has been advocated to avoid an excessively tight fundoplication. The use of an esophageal bougie carries a risk of iatrogenic complications, such as perforation or laceration of the viscera. However, there is equivocal evidence for the routine use in the surgical literature. Methods: We present a retrospective analysis of patients with Types 3 and 4 paraesophageal hiatal hernias who underwent laparoscopic hiatal hernia repair with fundoplication without the use of an esophageal bougie, between December 1, 2010 and February 28, 2020, by a single surgeon at a community-based, academic hospital. Patients with a diagnosis of achalasia and gastroesophageal dysmotility were excluded. Perioperative outcome measures included: recurrence; prolonged postoperative proton pump inhibitor use; dysphagia; re-operation, and mortality. Results: A total of 174 patients (34 males, 140 females) underwent laparoscopic hiatal hernia repair with fundoplication. The average age was 63-years old. Four patients (2.3%) developed dysphagia with narrowing of the gastroesophageal junction, with one patient (0.6%) requiring postoperative esophageal dilation with bougie and eventual re-operation. Postoperative proton pump inhibitor use was 31.0% after 1 month. Overall hernia recurrence rate was 14.9% and the rate of re-operation was 6.3%. Overall mortality was 0.6%. Conclusion: We conclude that laparoscopic hiatal hernia repair with fundoplication without an esophageal bougie is safe, effective, and efficient. Furthermore, bougie related risks are obviated with a comparable reported incidence of postoperative dysphagia and hiatal hernia recurrence.

Targeting residual risk: the rationale for the use of non-HDL cholesterol.

There is a wealth of epidemiological and clinical data linking low-density lipoprotein cholesterol (LDLc) with atherosclerotic cardiovascular disease. Numerous primary and secondary prevention trials have demonstrated that reduction in LDLc leads to significant decrease in cardiovascular event rates. However, patients continue to be at significant risk for recurrent events despite aggressive LDLc lowering, reflecting a substantial residual risk. Numerous parameters like apolipoprotein B, LDL particle size, number and non-high density lipoprotein cholesterol (non-HDLc) measurement have been used to assess and address this high residual risk. Herein, we discuss the rationale and the evidence supporting the use of non-HDLc. We also discuss therapeutic options and provide a practical approach to residual risk reduction from a primary care perspective.

Bivalirudin versus heparin in percutaneous coronary intervention-a systematic review and meta-analysis of randomized trials stratified by adjunctive glycoprotein IIb/IIIa strategy.

BACKGROUND: Bivalirudin has been shown to be associated with less major bleeding than heparin in patients undergoing percutaneous coronary intervention (PCI); but the confounding effect of concomitant glycoprotein IIb/IIIa inhibitors (GPI) limits meaningful comparison. We performed a systematic review and meta-analysis to compare bivalirudin to heparin, with and without adjunctive GPI in PCI. METHODS: We searched PubMed, Cochrane, EMBASE, CINAHL and WOS from January 2000 to December 2017 for clinical trials comparing bivalirudin to heparin, with and without adjunctive GPI during PCI. Cochrane's Q statistics were used to determine heterogeneity. Random effects model was used. RESULTS: Twenty-six comparison groups (22 original studies and 4 subgroup analyses) with 53,364 patients were included. Mean follow-up was 192±303 days. There was no difference between the two groups in all-cause mortality [risk ratio (RR: 0.93; 95% CI: 0.82-1.05, P=0.260), target vessel revascularization (TVR) (RR: 1.17; 95% CI: 0.93-1.46, P=0.174) or stroke (RR: 0.91; 95% CI: 0.71-1.18, P=0.490). Major bleeding was lower in the bivalirudin group with concomitant GPI in one or both arms (RR: 0.64; 95% CI: 0.53-0.77, P<0.001) and without (RR: 0.71; 95% CI: 0.51-0.99, P=0.041) provisional or routine GPIs. Bivalirudin appeared to have a higher risk of stent thrombosis (RR: 1.32; 95% CI: 1.04-1.68, P=0.022) and a trend towards more myocardial infarction (RR: 1.12; 95% CI: 0.98-1.28, P=0.098) though without statistical significance. However, exclusion of studies with GPI showed no difference in stent thrombosis or myocardial infarction with bivalirudin. CONCLUSIONS: Bivalirudin is associated with less major bleeding compared to heparin, regardless of GPI use. The lower anticoagulant effect of bivalirudin is linked with higher stent thrombosis and a trend towards more MI, however a confounding effect of GPI use in the heparin arm cannot be excluded.

A Review of Von Hippel-Lindau Syndrome.

Von Hippel-Lindau syndrome (VHL) is a familial neoplastic condition seen in approximately 1 in 36,000 live births. It is caused by germline mutations of the tumor suppressor gene VHL, located on the short arm of chromosome 3. While the majority of the affected individuals have a positive family history, up to 20% of cases arise from de novo mutations. VHL syndrome is characterized by the presence of benign and malignant tumors affecting the central nervous system, kidneys, adrenals, pancreas, and reproductive organs. Common manifestations include hemangioblastomas of the brain, spinal cord, and retina; pheochromocytoma and paraganglioma; renal cell carcinoma; pancreatic cysts and neuroendocrine tumors; and endolymphatic sac tumors. Diagnosis of VHL is prompted by clinical suspicion and confirmed by molecular testing. Management of VHL patients is complex and multidisciplinary. Routine genetic testing and surveillance using various diagnostic techniques are used to help monitor disease progression and implement treatment options. Despite recent advances in clinical diagnosis and management, life expectancy for VHL patients remains low at 40-52 years. This article provides an overview of the major clinical, histological, and radiological findings, as well as treatment modalities.

Case Report of Haemophilus parainfluenzae Sepsis in a Newborn Infant Following Water Birth and a Review of Literature.

Water birth has grown in popularity over the recent years. Although beneficial for mothers, there are concerns for the infants. There are previous reports of infection following water birth. The information regarding infection with Haemophilus parainfluenzae is limited. We report a case of a neonate with H. parainfluenzae bacteremia following water birth. The child was successfully treated with both antibiotic and supportive care. Previous reports of neonatal H. parainfluenzae infection are reviewed.

Outcomes of mitral valve repair compared with replacement in patients undergoing concomitant aortic valve surgery: a meta-analysis of observational studies.

Long-term superiority of mitral valve (MV) repair compared with replacement is well established in degenerative MV disease. In rheumatic heart disease, its advantages are unclear and it is often performed in conjunction with aortic valve (AV) replacement. Herein, we performed a systematic review and meta-analysis comparing outcomes of MV repair vs replacement in patients undergoing concomitant AV replacement. PubMed, Cochrane and Web of Science databases were searched up to 25 January 2014 for English language studies comparing outcomes of MV repair vs replacement in patients undergoing simultaneous AV replacement. Data of selected studies were extracted. Study quality, publication bias and heterogeneity were assessed. Analysis was performed using a random effects model (meta-analysis of observational studies in epidemiology recommendation). A total of 1202 abstracts/titles were screened. Of these, 20 were selected for full text review and 8 studies (3924 patients) were included in the final analysis: 1255 underwent MV repair and 2669 underwent replacement. Late outcome data were available in seven studies (cumulative follow-up: 15 654 patient-years). The early (in hospital and up to 30 days post-surgery) mortality [risk ratio (RR): 0.68, 95% confidence interval (CI): 0.53-0.87, P = 0.003] and late (>30 days post-surgery) mortality (RR: 0.76, 95% CI: 0.64-0.90 P = 0.001) were significantly lower in the MV repair group compared with the MV replacement group. The MV reoperation rate (RR: 1.89, 95% CI: 0.87-4.10, P = 0.108), thromboembolism (including valve thrombosis) (RR: 0.65, 95% CI: 0.38-1.13, P = 0.128) and major bleeding rates (RR: 0.88, 95% CI: 0.49-1.57, P = 0.659) were found to be comparable between the two groups. In a separate analysis of studies with exclusively rheumatic patients (n = 1106), the early as well as late mortality benefit of MV repair was lost (RR: 0.92, 95% CI: 0.44-1.90, P = 0.81 and RR: 0.69, 95% CI: 0.39-1.22, P = 0.199, respectively), whereas the MV reoperation rate became significantly higher (RR: 5.10, 95% CI: 1.62-16.05, P = 0.005) with MV repair. In patients undergoing concomitant mitral and AV surgery, MV repair is associated with improved early and late survival without any increased risk for mitral valve reoperation. However, in patients with rheumatic heart disease MV repair does not impart any survival advantage while the risk for MV reoperation remains significantly higher.
