Abstract
BACKGROUND The 5-factor frailty index (5-mFI), validated frailty index with Spearmen rho correlation of .95 and C statistic >.7 for predicting postoperative complications, can be preoperatively used to stratify patients prior to parastomal hernia repairs. METHODS Retrospective review of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database identified patients from 2015 to 2020. 5-mFI scores were calculated by adding one point for each comorbidity present: diabetes mellitus, congestive heart failure (CHF), hypertension requiring medication, severe chronic obstructive pulmonary disease (COPD), non-independent functional status. Primary endpoint was 30-day overall complications; secondary endpoints were 30-day readmission, reoperation, and discharge to care facility. RESULTS 2924 (52.2% female) patients underwent elective parastomal hernia repair. Univariate analysis showed 5-mFI > 2 had higher rates of overall (P = .008), pulmonary (P = .002), cardiovascular (P = .003)), hematologic (P = .003), and renal (P = .002) complications and higher rates of readmission (P = .009), reoperation (P = .001), discharge to care facility (P < .001), and death (P < .001). Multivariate analysis identified a 5-mFI of 2 or more as an independent risk factor for overall complications [OR: 1.40, 1.03-1.78; P = .032], pulmonary complications [2.97, 1.63-5.39; P < .001], hematological complications [1.60, 1.03-2.47; P = .035], renal complications [2.04, 1.19-3.46; P = .009], readmission [1.54, 1.19-1.99; P < .001], and discharge to facility [2.50, 1.66-3.77; P < .001]. Reoperation was not signification on multivariate analysis. CONCLUSIONS Parastomal hernia repair patients with 5-mFI score of >2 had higher risk of renal, cardiovascular, pulmonary, and hematologic complications, readmissions, longer hospitalization, discharge to care facility, and mortality, and can be useful during preoperative risk stratification.

Abstract
BACKGROUND Acute kidney injury (AKI) after surgery increases long-term risk of kidney dysfunction. The major risk factor for AKI after bariatric surgery is having preoperative renal insufficiency. Little is known about the outcomes and risk factors for developing AKI in patients undergoing bariatric surgery with normal renal function. OBJECTIVE We aimed to describe factors that may increase risk of AKI after primary bariatric surgery in patients without history of kidney disease. SETTING Academic hospital, United States. METHODS We performed a retrospective analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program data registry for patients aged ≥18 years undergoing laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass (LRYGB) from 2015 to 2019. Patients with diagnosis of chronic kidney disease were excluded. The primary outcome was incidence of AKI. Secondary outcomes included 30-day complications, readmissions, reoperations, and mortality. Univariate and multivariate analyses were performed to identify differences between patients with and without AKI. RESULTS A total of 747,926 patients were included in our analysis (laparoscopic sleeve gastrectomy = 73.1%, LRYGB = 26.8%). Mean age was 44.40 ± 11.94 years, with female predominance (79.7%). AKI occurred in 446 patients (.05%). Patients with postoperative AKI had higher rates of complications, readmissions, reoperations, and mortality. Significant predictors of AKI were male sex, history of venous thromboembolism, hypertension, limitation for ambulation, and LRYGB. High albumin levels and White race were protective factors. CONCLUSIONS New-onset AKI was associated with adverse 30-day outcomes in patients undergoing bariatric surgery. Male sex, venous thromboembolism, hypertension, limited ambulation, and LRYGB were independent predictors of AKI. Prospective studies are needed to better describe these results.

Abstract
BACKGROUND Severe obesity could be an independent risk factor for peripheral artery disease (PAD) and critical limb ischemia (CLI). Bariatric surgery reduces cardiac risk factors, decreasing cardiovascular morbidity and mortality in subjects with severe obesity. OBJECTIVES We aimed to describe the impact of bariatric surgery on risk of hospitalization due to PAD and CLI. SETTING Academic hospital. METHODS The National Inpatient Sample data collected from 2010 to 2015 were examined. Patients were classified as treatment and control groups. Treatment was defined as patients with a previous history of bariatric surgery, and control was defined as patients with a body mass index ≥35 without a history of bariatric surgery. The primary outcome was hospitalization due to PAD; secondary outcomes were CLI, revascularization, major amputation, length of hospital stay (LOS), and total cost of hospitalization. Univariate and multivariate analyses were performed to assess the differences between groups. RESULTS There were a total of 2,300,845 subjects: 2,004,804 controls and 296,041 treatment patients. Hospitalization rate for PAD was significantly lower compared to the control group (.10% versus .21%, P < .0001), which was confirmed after adjusting for covariables (control versus treatment: odds ratio= 1.20, confidence interval: 1.15-1.47). Subgroup analysis showed patients without a history of bariatric surgery had a higher prevalence of CLI (59.3% versus 52.4%, P < .0219) and a higher mean LOS (6.7 versus 5.7 days, P = .0023) and cost of hospitalization (78.756 versus 72.621$, P = .0089), with no significant differences in other outcomes. After multivariate analysis, only LOS and total costs were significantly different. CONCLUSIONS Bariatric surgery may decrease the risk of hospitalization due to PAD, similarly to the LOS and total cost of hospitalization. Prospective studies should be performed to describe this relationship.

Abstract
BACKGROUND Stroke is the second leading cause of death worldwide and fifth in the United States, and it represents the major cause of disability in older adults. OBJECTIVE We aimed to determine the risk of acute ischemic stroke (AIS) in individuals with obesity with a history of transient ischemic attack (TIA) compared with patients with a history of bariatric surgery. SETTING Academic hospital, United States. METHODS Using the Nationwide Inpatient Sample (NIS) database from 2010 to 2015, we retrospectively identified patients with obesity and past medical history of TIA and divided them into 2 groups: a treatment group of patients who underwent bariatric surgery, and a control group of patients with obesity. We compared incidence of new AIS in both groups using a univariate analysis and multivariate regression model. Covariates included were lifestyle (smoking status, alcohol habits, cocaine use), family history of stroke, co-morbidities (diabetes, hypertension, hyperlipidemia, atrial fibrillation) and long-term medical treatment (antiplatelet/antithrombotic treatment). RESULTS A total of 91,640 patients met inclusion criteria, of which treatment patients were 12.3% (n = 11,284) and control patients 87.6% (n = 80,356). The average age of the treatment group was 62.9 ± 17.08 years, and the average of the control was 59.6 ± 12.74 years. The rate of AIS in the treatment group was significantly lower compared with the control group (2.8% versus 4.2%, P < .0001). After adjusting for covariables, the risk difference of AIS was still significant between groups (odds ratio = 1.33, P < .0001), showing that patients in the treatment group were less likely to have AIS compared with the control group. CONCLUSIONS After analyzing nationwide information, we conclude bariatric surgery helps decrease risk of AIS in patients with a history of TIA. However, this comparison is limited by the nature of the database; further studies are needed to better understand these results.

Abstract
BACKGROUND The population undergoing bariatric surgery (BaS) has many cardiovascular risk factors that can lead to significant perioperative cardiovascular morbidity. OBJECTIVES We aimed to examine trends in the incidence of major adverse cardiovascular and cerebrovascular events (MACCE) after BaS. SETTING Academic Hospital, United States METHODS: We performed a retrospective analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) data registry for patients aged ≥18 years undergoing laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) from 2015 to 2019. Data on demographics, co-morbidities, and type of procedure were collected. MACCE was defined as a composite variable including perioperative acute myocardial infarction (AMI), cardiac arrest requiring cardiopulmonary resuscitation, acute stroke, and all-cause mortality. We utilized the Cochrane-Armitage and Jonckheere-Terpstra tests to assess for significant trend changes throughout the years. RESULTS A total of 752,722 patients were included in our analysis (LSG = 73.2%, LRYGB = 26.8%). Postoperative MACCE occurred in 1058 patients (.14%), and was more frequent in patients undergoing LRYGB (.20%). The frequency of MACCE declined from .17% to .14% (P = .053), driven by a decline in the frequency of AMI (.04% to .02%, P = .002), cardiac arrest (.05% to .04%, P = .897), and all-cause death (.11% to .08%, P = .040), but with an increase in perioperative stroke (.01% to .02%, P = .057). CONCLUSION The overall risk of MACCE after BaS is .14% and has been declining in the last 5 years. This trend is likely multifactorial and further analysis is necessary to provide a detailed explanation.

Abstract
BACKGROUND Obesity independently increases the risk of hospitalization due to viral respiratory infections, including influenza virus and, more recently, severe acute respiratory syndrome coronavirus 2. As an independent risk factor, obesity impairs the immune response to viral infections and decreases the effectiveness of immunizations. OBJECTIVES Using influenza as a proxy, we aimed to determine the impact of bariatric surgery (BaS) on the risk of hospitalization due to viral respiratory infections. SETTING Academic hospital, United States. METHODS National (Nationwide) Inpatient Sample data collected from 2010 to 2015 were examined. Patients were classified as treatment and control groups. Treatment subjects were defined as patients with a history of BaS and control subjects as patients with a body mass index ≥35 kg/m2 and without a history of BaS. Any hospitalization with influenza as a primary diagnosis was identified. Univariate analysis and multivariate regression models were performed to assess the differences between groups. RESULTS A total of 2,300,845 subjects were reviewed, of which 2,004,804 were control subjects and 296,041 were treated patients. Univariate analysis showed that the hospitalization rate in the treatment group was significantly lower than in the control group (.007% versus .019%, P < .0001), which was confirmed after adjusting for covariables (control versus treatment: odds ratio = 2.21, P = .0010). CONCLUSIONS BaS may decrease the risk of hospitalization due to influenza, but further prospective studies are needed to confirm these results. We also suggest that these results should be translated into the development of similar studies to determine the impact of BaS on the incidence and severity of the coronavirus disease 2019.

Abstract
BACKGROUND The incidence of obesity has been steadily increasing, especially in developed countries. Also, obesity is considered one of the modifiable risk factors of kidney cancer. OBJECTIVES This study aims to determine the impact of bariatric surgery-induced weight loss on the prevention of kidney cancer. SETTING Academic Hospital, United States. METHODS The National (Nationwide) Inpatient Sample (NIS) was queried for the period 2010 to 2015 for first-time kidney cancer-related hospitalization, used as a proxy for cancer incidence, in patients with a history of bariatric surgery (cases) and patients with obesity but no history of bariatric surgery (controls). Patients with a previous diagnosis of cancer were excluded from the analysis. In order to identify comparable patients, all controls had to have a body mass index ≥35 kg/m2, as per the existing qualification criteria for bariatric surgery. The International Classification of Diseases-9 codes (ICD-9) was used to identify admissions for kidney cancer. A univariate analysis was conducted to compare demographics and co-morbidities between groups. A multivariate logistic regression model was performed to assess differences between surgical and control groups and adjust for independent variables such as smoking history and family history of malignancy. All percentages and means (with confidence intervals [CIs]) were weighted. RESULTS A total of 2,300,845 were included in the analysis, of which 2,004,804 controls-subjects, with a mean age of 54.4 ± .05 years, and 296,041 treatment-subjects, with a mean age of 51.9 ± .05 years. Demographics and co-morbidities, such as tobacco use, diabetes, and hypertension, were also measured. Patients with a history of bariatric surgery were significantly less likely to experience renal cancer than patients without a history of bariatric surgery, with 5935 cases in the control group and 684 in the case group (P < .0001). After a multivariate logistic regression was performed, the OR was 1.10 (95% CI: 1.02-1.22, P < .0224). CONCLUSION Our finding suggests that bariatric surgery-induced weight loss could significantly prevent first-time kidney cancer-related hospitalizations in patients with obesity. Prospective studies are needed to confirm our findings.

Abstract
BACKGROUND Perineal wound complications after extralevator abdominoperineal resection for cancer are common with no consensus on optimal reconstructive technique. We compared short- and long-term results of laparoscopic abdominoperineal resection with open surgery ± vertical rectus abdominis myocutaneous flap. METHODS This is a single-institution retrospective observational study of 204 consecutive patients with advanced low rectal cancer who underwent extralevator abdominoperineal resection from January 2010 to August 2020. Main outcome measures were short-term results, wound complications, and incisional, parastomal, and perineal hernia rates. RESULTS Fifty-five (27%) patients had a laparoscopic approach, 80 (39%) open, and 69 (33%) open + vertical rectus abdominis myocutaneous flap. The groups had similar median length of follow up (P = .75). Patients' age and radiation, intraoperative and postoperative complications, mortality, and readmission rates were similar among the 3 groups. Perineal wound infection and dehiscence rates were not influenced by surgical approach. Laparoscopy resulted in higher perineal (7.3 vs 2.5 vs 0%; P = .047) and parastomal (23.6 vs 13.8 vs 5.8%; P = .016) hernia rates than did open or open + vertical rectus abdominis myocutaneous flap. Patients who underwent an open approach had a higher body mass index and rate of prior surgeries and preoperative ostomies. Laparoscopic and open approaches had significantly shorter operative times (300 vs 303 vs 404 minutes, respectively; P < .001) and shorter length of stay (7.6 vs 10.8 vs 11.12, respectively; P = .006) compared to open with a flap approach. CONCLUSION Open and open + vertical rectus abdominis myocutaneous flap approaches for reconstruction after abdominoperineal resection had lower parastomal and perineal hernias rates but similar postoperative morbidity as did the laparoscopic approach.

Abstract
BACKGROUND Body fat distribution is highly associated with metabolic disturbances. Skeletal muscle plays an important role in glucose metabolism, as it serves as an important organ for glucose storage in the form of glycogen. In fact, low muscle mass has been associated with metabolic syndrome, type 2 diabetes (T2D), systemic inflammation, and decreased survival. OBJECTIVES To compare the relationship between visceral abdominal fat (VAF) and fat free mass (FFM) with the improved glucose metabolism after bariatric surgery. SETTING University hospital, United States. METHODS A retrospective review was performed of all patients who underwent bariatric surgery between 2011 and 2017 at a university hospital in the United States. In severely obese patients with T2D, we measured the VAF via abdominal computed tomography scan and we calculated the FFM preoperatively and at a 12-month follow-up. Data collected included baseline demographic characteristics and perioperative parameters, such as treatment for hypertension (HTN) and T2D, body mass index (BMI), glycated hemoglobin (HbA1C), glucose, and lipid profile. RESULTS A total of 25 patients met the inclusion criteria. The average age was 52.5 ± 11.6 years. The initial BMI was 41.41 ± 5.7 kg/m2 and the postoperative BMI was 31.7 ± 6.9 kg/m2 (P < .0001). The preoperative VAF volume was 184.6 ± 90.2 cm3 and the postoperative VAF volume was 93.8 ± 46.8 cm3 at the 12-month follow-up (P < .0001). The preoperative FFM was 55.2 ± 11.4 kg and the postoperative FFM was 49.1 ± 12 kg (P < .072). The preoperative HbA1C was 5.8% ± .9%, which decreased postoperatively to 5.3% ± .4% at the 12-month follow-up (P < .013). CONCLUSION Bariatric surgery has been demonstrated to be an effective treatment modality for severe obesity and T2D. Our results suggest that at 12 months, there is a reduction in VAF and HbA1C without a significant loss of FFM. Further prospective studies are needed to better understand these findings.

Abstract
OBJECTIVE To survey inner-city prostitutes' perceived health needs. METHODS One hundred forty street prostitutes in Washington DC, were surveyed to determine their perceived health needs, in addition to levels of post traumatic stress disorder (PTSD). RESULTS The final sample comprised 100 individuals, representing 3 subgroups of prostitutes, female, male, and transgender male. Major health needs included protection from physical and sexual assault, social support, counseling, addictions treatment, job training, and medical care. Over 42% of the population was identified as meeting established criteria for PTSD. CONCLUSION Effective program development for inner-city prostitutes needs to acknowledge the presence of distinct subpopulations and the pervasive influence of PTSD on health status.
