Front Physiol 2022; 13:955702. [PMID: 36117715 PMCID: PMC9470752 DOI: 10.3389/fphys.2022.955702] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2022] [Accepted: 07/22/2022] [Indexed: 11/13/2022] Open
Abstract
Objective: Oxygenation impairment is a common complication of acute aortic syndrome (AAS) patients after surgical repair. The aim of this study is to identify the relationship between body mass index (BMI) and the risk of postoperative oxygenation impairment in AAS patients. Methods: A total of 227 consecutive patients who were diagnosed as AAS and underwent surgical repair were recruited. They were divided into two groups based on the postoperative oxygenation impairment (non-oxygenation impairment group and oxygenation impairment group). Logistic regression was conducted to evaluate the association between BMI and the risk of oxygenation impairment after surgery. Dose-response curve and subgroup analysis were used to test the reliability of the results of regression analysis. A meta-analysis was then performed to further confirm these results using Pubmed, Embase, and Web of Science databases. Results: For the retrospective study, a significant association was observed after adjusting for a series of variables. BMI was significantly correlated with postoperative oxygenation impairment in patients with AAS (OR, 95% CI, P: 1.27, 1.17–1.46, 0.001). Compared with the normal weight group (18.5 kg/m2 ≤ BMI <23.0 kg/m2), patients with excessive BMI were at a higher risk of oxygenation impairment for the overweight group (23.0 kg/m2 ≤ BMI <25 kg/m2) and obesity group (BMI ≥25 kg/m2) (OR, 95% CI, P: 4.96, 1.62–15.15, 0.005; 9.51, 3.06–29.57, <0.001). The dose-response curve showed that the risk of oxygenation impairment after surgery increased with the increased BMI. Besides, subgroup analysis showed that AAS patients who have an excess weight with a TNF-α ≥ 8.1 pg/ml carried an excess risk of postoperative oxygenation impairment. For the meta-analysis, the pooled result also indicated that AAS patients with high BMI had a significantly increased risk of oxygenation impairment after surgery (OR, 95% CI, P: 1.40, 1.18–1.66, 0.001). Conclusion: Excessive BMI was an independent risk factor for AAS with postoperative oxygenation impairment.

Abstract
OBJECTIVE The study aimed to determine the relationship between body mass index (BMI) and the risk of acute aortic syndrome (AAS) with preoperative oxygenation impairment. METHODS A meta-analysis of published observational studies involving BMI and AAS with preoperative oxygenation impairment was conducted. A total of 230 patients with AAS were enrolled for retrospective analysis. All patients were divided into 2 groups (Non-oxygenation impairment group and Oxygenation impairment group). Logistic regression analysis was performed to assess the relation between BMI and the risk of preoperative oxygenation impairment after the onset of AAS. Dose-response relationship curve and subgroup analysis were conducted to test the reliability of BMI as an independent factor of it. RESULTS For the meta-analysis, the quantitative synthesis indicated that excessive BMI increased the risk of preoperative oxygenation impairment (OR: 1.30, 95% CI: 1.05-1.60, P heterogeneity = 0.001). For the retrospective analysis, a significant association was observed after adjusting for a series of variables. BMI was significantly related to preoperative oxygenation impairment after the onset of AAS (OR: 1.34, 95% CI: 1.15-1.56, p <0.001), and compared with normal weight group (18.5 kg/m2 ≤ BMI < 23.0 kg/m2), the individuals with excessive BMI were at higher risk of preoperative oxygenation impairment for the obese group (BMI ≥ 25 kg/m2) (OR: 17.32, 95% CI: 4.03-74.48, p <0.001). A J-shape curve in dose-response relationship analysis further confirmed their positive correlation. Subgroup analysis showed that diastolic blood pressure (DBP) ≥ 90mmHg carried an excess risk of preoperative oxygenation impairment in obese patients. CONCLUSION Excessive BMI was an independent risk factor for AAS with preoperative oxygenation impairment.

Abstract
BACKGROUND With the growing number of adults requiring operations for CHD, prolonged length of stay adds an additional burden on healthcare systems, especially in developing countries. This study aimed to identify factors associated with prolonged length of stay in adult patients undergoing operations for CHD. METHODS This retrospective study included all adult patients (≥18 years) who underwent cardiac surgery with cardiopulmonary bypass for their CHD from 2011 to 2016 at a tertiary-care private hospital in Pakistan. Prolonged length of stay was defined as hospital stay >75th percentile of the overall cohort (>8 days). RESULTS This study included 166 patients (53.6% males) with a mean age of 32.05 ± 12.11 years. Comorbid disease was present in 59.0% of patients. Most patients underwent atrial septal defect repair (42.2%). A total of 38 (22.9%) patients had a prolonged length of stay. Post-operative complications occurred in 38.6% of patients. Multivariable analysis showed that pre-operative body mass index (odds ratio: 0.779; 95% confidence interval: 0.620-0.980), intraoperative aortic cross-clamp time (odds ratio: 1.035; 95% confidence interval: 1.009-1.062), and post-operative acute kidney injury (odds ratio: 7.392; 95% confidence interval: 1.036-52.755) were associated with prolonged length of stay. CONCLUSION Predictors of prolonged length of stay include lower body mass index, longer aortic cross-clamp time, and development of post-operative acute kidney injury. Shorter operations, improved pre-operative nutritional optimisation, and timely management of post-operative complications could help prevent prolonged length of stay in patients undergoing operations for adult CHD.

Abstract
Patients with obesity are at increased risk for coronary artery disease and heart failure and often present with symptoms of dyspnea, fatigue, edema, or chest pain. Echocardiography is frequently used to help distinguish whether these symptoms are due to cardiac disease. Unfortunately, obesity has a significant impact on image quality because of signal attenuation. Ultrasound-enhancing agents may improve the detection of structural remodeling and subclinical left ventricular dysfunction in patients with obesity. Assessment of chamber sizes and cardiac remodeling in severely obese subjects must be interpreted with caution, however, as the current recommendations for indexing cardiac chamber sizes to body size may lead to false conclusions about chamber volumes or mass, particularly in settings in which weight is changing. As a result of increases in stroke volume and cardiac output, obesity may exacerbate hemodynamic compromise in obstructive structural or valvular disease. With regard to assessment of ischemic heart disease, stress echocardiography can effectively risk-stratify patients with obesity and may have advantages over other noninvasive modalities. In general, transesophageal echocardiography is safe in patients with obesity, although some precautions should be observed. Stress echocardiography using the transesophageal approach is an alternative for preoperative or ischemia evaluation in patients with suboptimal transthoracic views.

Abstract
OBJECTIVE To determine the relationship between obesity and the risk of AKI after cardiac surgery (CS-AKI) in a cohort study. METHODS A total of 1,601 patients undergoing cardiac surgery were collected and their incidence of CS-AKI was recorded. They were divided into underweight, normal weight, overweight, and obese groups. Logistic regression was used to estimate the association between BMI (body mass index) and CS-AKI risk. Then, a meta-analysis of published cohort studies was conducted to confirm this result using PubMed and Embase databases. RESULTS A significant association was observed in this independent cohort after adjusting age, gender, hypertension and New York Heart Association classification (NYHA) class. Compared with normal BMI group (18.5 ≤ BMI < 24.0), the individuals with aberrant BMI level had an increased AKI risk (OR: 1.68, 95% CI: 1.01-2.78) for BMI < 18.5 group and (OR: 1.43, 95% CI: 0.96-2.15) for BMI ≥ 28.0. Interestingly, the U-shape curve showed the CS-AKI risk reduced with the increasing of BMI when BMI ≤ 24.0. As BMI increases with BMI > 24.0, the risk of developing CS-AKI increased significantly. In the confirmed meta-analysis, compared with normal weight, overweight group with cardiac surgery had higher AKI risk (OR: 1.28, 95% CI: 1.16-1.41, Pheterogeneity = 0.49). The similar association was found in obesity subgroup (OR: 1.79, 95% CI: 1.57-2.03, Pheterogeneity = 0.42). CONCLUSION In conclusion, the results suggested that abnormal BMI was a risk factor for CS-AKI independently.

Abstract
Background: Pain management in emergency departments is a complex objective. The absence of a care pathway or a high level of activity complicates diagnostic or analgesic therapeutic strategies. Medical innovation can impact both individual practices and the functioning of an emergency department. Objective: We then wanted to understand how medico-economic studies on pain were carried out in an emergency department. Study design: We reviewed the literature of the last 20 years (between 1998 and 2018). Setting: Of 846 titles screened, a total of 268 abstracts qualified for further screening, and 578 titles were excluded. A total of 14 studies qualified for inclusion in the review. Studies on medico-economics in an emergency department are very diverse. None of the methods used are identical; the studies differ in their very nature (prospective, retrospective, cost-effectiveness, etc.) and the determination of emergency room costs differs according to the part of the world studied. In addition, organizational impact is rarely measured, although it is an essential dimension for choosing or not a medical innovation.

Abstract
OBJECTIVES Our study aimed to compare overweight and healthy-weight pediatric trauma patient outcomes, specifically with respect to hospital length of stay and resource utilization. We hypothesized that overweight pediatric trauma patients would have increased hospital length of stay and radiographic study use compared with their healthy-weight counterparts. METHODS This was a prospective, observational, cohort study of pediatric trauma patients aged 2 to 19 years presenting to an urban pediatric emergency department over a period of 1 year. Using measured height and weight values, body mass index (BMI) for age was calculated and plotted on the Centers for Disease Control and Prevention BMI-for-age growth charts. Patients were followed up throughout their hospitalization, and the following items were recorded: trauma alert level, mechanism of injury, age, sex, race, Glasgow Coma Scale score, total number of days in hospital, total number of intensive care unit days, total number of radiographs obtained, total number of computed tomography scans obtained, and mechanism of injury. RESULTS Our study population included 109 subjects. The mean age of the subjects was 9.7 years. The number of patients meeting the definition of obese (BMI for age ≥95%) was 15, or 14% of the total study population. There was no significant difference between the overweight cohort and the healthy-weight cohort found among any of the variables recorded and analyzed. CONCLUSIONS Although there are many chronic conditions in children associated with obesity, in the case of trauma, it does not seem to be a strong concern. A continued focus on preventing and reversing childhood obesity for other physical and mental health outcomes may be more important.

Abstract
BACKGROUND Multiple Sclerosis (MS) results from genetic predisposition and environmental variables, including elevated Body Mass Index (BMI) in early life. This study addresses the effect of BMI on the epigenome of monocytes and disease course in MS. METHODS Fifty-four therapy-naive Relapsing Remitting (RR) MS patients with high and normal BMI received clinical and MRI evaluation. Blood samples were immunophenotyped, and processed for unbiased plasma lipidomic profiling and genome-wide DNA methylation analysis of circulating monocytes. The main findings at baseline were validated in an independent cohort of 91 therapy-naïve RRMS patients. Disease course was evaluated by a two-year longitudinal follow up and mechanistic hypotheses tested in human cell cultures and in animal models of MS. FINDINGS Higher monocytic counts and plasma ceramides, and hypermethylation of genes involved in negative regulation of cell proliferation were detected in the high BMI group of MS patients compared to normal BMI. Ceramide treatment of monocytic cell cultures increased proliferation in a dose-dependent manner and was prevented by DNA methylation inhibitors. The high BMI group of MS patients showed a negative correlation between monocytic counts and brain volume. Those subjects at a two-year follow-up showed increased T1 lesion load, increased disease activity, and worsened clinical disability. Lastly, the relationship between body weight, monocytic infiltration, DNA methylation and disease course was validated in mouse models of MS. INTERPRETATION High BMI negatively impacts disease course in Multiple Sclerosis by modulating monocyte cell number through ceramide-induced DNA methylation of anti-proliferative genes. FUND: This work was supported by funds from the Friedman Brain Institute, NIH, and Multiple Sclerosis Society.

Abstract
OBJECTIVES This study was conducted to clarify the relationship between body mass index and mitral valve (MV) surgery and to determine whether an 'obesity paradox' exists in the context of surgery for degenerative MV disease. METHODS In this retrospective single-centre study, we analysed data from 715 patients who underwent mitral surgery for degenerative disease from 2000 to 2015. Patients were classified according to body mass index: underweight (<20 kg/m2), normal weight (20-24.99 kg/m2), overweight (25-29.99 kg/m2) and obese (≥30 kg/m2). Early and long-term results were investigated. Multivariable analysis was conducted to identify risk factors for long-term mortality. RESULTS Mean follow-up was 67 ± 44 months (range 0-190 months). There were no differences between groups regarding 30-day mortality (P = 0.35), stroke (P = 0.45), reoperation for bleeding (P = 0.9) and length of hospital stay (P = 0.31). Obese patients were at increased risk of acute kidney injury when compared with normal weight patients (17% vs 5%; P = 0.03) but not when compared with the other groups; this was confirmed within the subgroup with depressed ejection fraction (42% vs 10%, P = 0.02). No differences in long-term survival were found across groups for all patients (P = 0.62) and for patients with depressed ejection fraction (P = 0.6), with a trend towards worse survival in obese patients undergoing MV repair (P = 0.06). Survival in obese patients undergoing repair was significantly worse than that in obese patients undergoing replacement (P = 0.04). CONCLUSIONS An 'obesity paradox' was not demonstrated after surgery for degenerative MV disease. Obese patients are more prone to acute kidney injury and have worse late survival after MV repair.

Abstract
BACKGROUND Prior research reveals that overweight patients have higher emergency department (ED) utilization rates, longer length of stay, and face increased misdiagnosis risk. OBJECTIVE The objective of this study was to evaluate the association between obesity and ED patient satisfaction. METHODS This study was a cross-sectional study. A convenience sample of inner-city ED patients completed a written survey, then rated overall satisfaction with ED care (10-point scale), and rated components of satisfaction (4-point scale; never to always). Body mass index (BMI) was calculated using triage records (obesity = BMI >30). RESULTS Five hundred and sixty-four patients were included in the study group (50.5%: obese, 55.4%: female, mean age: 43.2 ± 25.4 years). With respect to overall visit satisfaction (rating 8 or greater on 10-point scale), bivariate analysis revealed no differences between nonobese versus obese patients (74.6% vs. 73.9%; P = 0.85). There were no significant differences for score of 4 (always) for components of ED satisfaction: physician courtesy (87.9% vs. 90.4%; P = 0.34), nurse courtesy/respect (89.2% vs. 88.7%; P = 0.87), doctor listened (85.4% vs. 87.1%; P = 0.5), doctor explained (80.2% vs. 85.0%; P = 0.14), and recommend to friend (72.5% vs. 81.1%; P = 0.02). Within our multivariate model, obesity was not associated with overall satisfaction (scores of 8 or greater) (P = 0.97; odds ratio = 0.99 [95% confidence interval = 0.65-1.5]). CONCLUSIONS Despite research that suggests that overweight patients have characteristics of their ED visit that might increase dissatisfaction risk, we found no difference in satisfaction scores between nonobese and obese patients.

Abstract
OBJECTIVES To evaluate the health service requirements of obese patients admitted to an Emergency Short Stay Unit (ESSU) and specifically compare length of stay (LOS), failure of ESSU management, and rates of investigations and allied health interventions among obese and non-obese patients. METHODS A prospective cohort study, using convenience sampling was conducted. The body mass index (BMI) of participants was calculated and those with a BMI of ⩾30 were allocated to the obese group, and those that had a BMI of <30 to the non-obese group. Data collected included demographics, admission diagnosis, time and date of ESSU admission and discharge, discharge disposition, radiological investigations, and referrals made to allied health personnel during ESSU admission. RESULTS There were 262 patients that were recruited sub-grouped into 127 (48.5%) obese participants and 135 (51.5%) non-obese participants with similar sex and diagnostic category distributions. The mean LOS in ESSU was similar - 11.5h (95% CI: 9.9-13.1) for obese patients and, 10.2h (95% CI: 8.8-11.6) for non-obese patients (p=0.21). Failure rates of ESSU management, defined as inpatient admission to hospital, were also similar with 29 (22.8%) obese patients admitted to hospital compared to 25 (18.5%) non-obese patients (p=0.39). Plain X-ray requests were significantly higher among obese patients (71.6 vs 53.3%; p=0.002), as was the rate of allied health interventions (p=0.001). CONCLUSION There was no significant difference in inpatient admission rates or LOS between obese and non-obese patients managed in the ESSU. Provisions for increased rate of investigations and allied health interventions for obese patients may facilitate timely assessment and disposition from ESSU.

Abstract
Acute pulmonary embolism (PE) can diminish patient quality of life (QoL). The objective was to test whether treatment with tenecteplase has an independent effect on a measurement that reflects QoL in patients with submassive PE. This was a secondary analysis of an 8-center, prospective randomized controlled trial, utilizing multivariate regression to control for predefined predictors of worsened QoL including: age, active malignancy, history of PE or deep venous thrombosis (DVT), recurrent PE or DVT, chronic obstructive pulmonary disease and heart failure. QoL was measured with the physical component summary (PCS) of the SF-36. Analysis included 76 patients (37 randomized to tenecteplase, 39 to placebo). Multivariate regression yielded an equation f(8, 67), P < 0.001, with R(2) = 0.303. Obesity had the largest effect on PCS (β = -8.6, P < 0.001), with tenecteplase second (β = 4.73, P = 0.056). After controlling for all interactions, tenecteplase increased the PCS by +5.37 points (P = 0.027). In patients without any of the defined comorbidities, the coefficient on the tenecteplase variable was not significant (-0.835, P = 0.777). In patients with submassive PE, obesity had the greatest influence on QoL, followed by use of fibrinolysis. Fibrinolysis had a marginal independent effect on patient QoL after controlling for comorbidities, but was not significant in patients without comorbid conditions.

Cost-effectiveness of quantitative pretest probability intended to reduce unnecessary medical radiation exposure in emergency department patients with chest pain and dyspnea. Acad Emerg Med 2015; 22:525-35. [PMID: 25899550 DOI: 10.1111/acem.12648] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2014] [Revised: 11/09/2014] [Accepted: 11/25/2014] [Indexed: 01/05/2023]
Abstract
OBJECTIVES Quantitative pretest probability (qPTP) incorporated into a decision support tool with advice can reduce unnecessary diagnostic testing among patients with symptoms suggestive of acute coronary syndrome (ACS) and pulmonary embolism (PE), reducing 30-day costs without an increase in 90-day adverse outcomes. This study estimates long-term (beyond 90-day) costs and outcomes associated with qPTP. The authors hypothesized that qPTP reduces lifetime costs and improves outcomes in low-risk patients with symptoms suggestive of ACS and PE. METHODS This was a cost-effectiveness analysis of a multicenter, randomized controlled trial of adult emergency patients with dyspnea and chest pain, in which a clinician encountering a low-risk patient with symptoms suggestive of ACS or PE conducted either the intervention (qPTP for ACS and PE with advice) or the sham (no qPTP and no advice). Effect of the intervention over a patient's lifetime was assessed using a Markov microsimulation model. Short-term costs and outcomes were from the trial; long-term outcomes and costs were from the literature. Outcomes included lifetime transition to PE, ACS, and intracranial hemorrhage (ICH); mortality from cancer, ICH, PE, ACS, renal failure, and ischemic stroke; quality-adjusted life-years (QALYs); and total medical costs compared between simulated intervention and sham groups. RESULTS Markov microsimulation for a 40-year-old patient receiving qPTP found lifetime cost savings of $497 for women and $528 for men, associated with small gains in QALYs (2 and 6 days, respectively) and lower rates of cancer mortality in both sexes, but a reduction in ICH only in males. Sensitivity analysis for patients aged 60 years predicted that qPTP would continue to save costs and also reduce mortality from both ICH and cancer. Use of qPTP significantly reduced the lifetime probability of PE diagnosis, with lower probability of death from PE in both sexes aged 40 to 60 years. However, use of qPTP reduced the rate of ACS diagnosis and death from ACS at age 40, but increased the death rate from ACS at age 60 for both sexes. CONCLUSIONS Widespread use of a combined qPTP for both ACS and PE has the potential to decrease costs by reducing diagnostic testing, while improving most long-term outcomes in emergency patients with chest pain and dyspnea.
