Excessive lipid accumulation in white adipose tissue (WAT) results in adipocyte hypertrophy and chronic low-grade inflammation, which is the major cause of obesity-associated insulin resistance and consequent metabolic disease. The development of beige adipocytes in WAT (browning of WAT) increases energy expenditure and has been considered as a novel strategy to counteract obesity. Thymoquinone (TQ) is the main bioactive quinone derived from the plant Nigella Sativa and has antioxidative and anti-inflammatory capacities. Fish oil omega 3 (ω3) enhances both insulin sensitivity and glucose homeostasis in obesity, but the involved mechanisms remain unclear. The aim of this study is to explore the effects of TQ and ω3 PUFAs (polyunsaturated fatty acids) on obesity-associated inflammation, markers of insulin resistance, and the metabolic effects of adipose tissue browning. 3T3-L1 cells were cultured to investigate the effects of TQ and ω3 on the browning of WAT. C57BL/6J mice were fed a high-fat diet (HFD), supplemented with 0.75% TQ, and 2% ω3 in combination for eight weeks. In 3T3-L1 cells, TQ and ω3 reduced lipid droplet size and increased hallmarks of beige adipocytes such as uncoupling protein-1 (UCP1), PR domain containing 16 (PRDM16), fibroblast growth factor 21 (FGF21), Sirtuin 1 (Sirt1), Mitofusion 2 (Mfn2), and heme oxygenase 1 (HO-1) protein expression, as well as increased the phosphorylation of Protein Kinase B (AKT) and insulin receptors. In the adipose tissue of HFD mice, TQ and ω3 treatment attenuated levels of inflammatory adipokines, Nephroblastoma Overexpressed (NOV/CCN3) and Twist related protein 2 (TWIST2), and diminished adipocyte hypoxia by decreasing HIF1α expression and hallmarks of beige adipocytes such as UCP1, PRDM16, FGF21, and mitochondrial biogenesis markers Peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC1α), Sirt1, and Mfn2. Increased 5′ adenosine monophosphate-activated protein kinase (AMPK) and acetyl-CoA carboxylase (ACC) phosphorylation and HO-1 expression were observed in adipose with TQ and ω3 treatment, which led to increased pAKT and pIRS1 Ser307 expression. In addition to the adipose, TQ and ω3 also increased inflammation and markers of insulin sensitivity in the liver, as demonstrated by increased phosphorylated insulin receptor (pIR tyr972), insulin receptor beta (IRβ), UCP1, and pIRS1 Ser307 and reduced NOV/CCN3 expression. Our data demonstrate the enhanced browning of WAT from TQ treatment in combination with ω3, which may play an important role in decreasing obesity-associated insulin resistance and in reducing the chronic inflammatory state of obesity.

Background: Elderly patients admitted emergently for ventral hernia may have high rates of complications, including morbidity and mortality. The goal of this study was to retrospectively assess risk factors for in-hospital mortality for elderly patients admitted emergently with a primary diagnosis of ventral hernia. Methods: Elderly patients with ventral hernia that required emergency admission were analyzed using the National Inpatient Sample database, 2005-2014. Demographics, clinical data, and outcomes were collected. The relationship between mortality and the predictors was assessed using a stratified analysis, multivariable logistic regression model, and multivariable generalized additive model. Results: A total of 33,700 elderly patients were analyzed. The mean (SD) age for males and females was 75 (7.25) and 76.25 (7.75) years, respectively (p<0.001). Approximately 70% of the patients were females. The mean (SD) hospital length of stay (HLOS) was 6.3 (6.5) and 11.6 (13.7) days in survived vs. deceased patients (p<0.001), respectively. Gangrene was present in 1.5% of survivors vs. 5.6% of deceased (p<0.001) patients. Intestinal obstruction was observed in 78% of survivors vs. 88% of deceased patients (p<0.001). Of the 8,554 cases managed non-operatively, 2.1% died. In contrast, in the 25,163 patients who were operated upon, the mortality rate was 2.9%. The mean (SD) HLOS was 7.39 (7.41) days in patients who had an operation vs. 3.82 (3.48) days in those who did not (p<0.0001). Time to operation was 1.12 (1.97) days in survivors vs. 1.81 (3.02) days in deceased patients (p<0.001). In the final multivariable logistic regression model for patients who underwent an operation, delayed operation, elderly male, frailty, invasive diagnostic procedures and presence of gangrene or obstruction were the main risk factors for mortality. In the final model for patients who did not have an operation, age, frailty, presence of gangrene or obstruction and HLOS were the main risk factors for mortality. Conclusion: A delayed operation in elderly males and frail patients with intestinal obstruction or gangrene admitted emergently due to ventral hernia significantly increases mortality in this setting.

Background The study explored determinants of mortality of admitted emergently patients with the primary diagnosis of hemorrhoids, during the years 2005-2014. Methods Demographics, clinical data, and outcomes were obtained from the National Inpatient Sample, 2005-2014, in elderly (65+ years) and non-elderly adult patients (18-64 years) with hemorrhoids who underwent emergency admission. Multivariable logistic regression model with backward elimination was used to identify predictors of mortality. Results 25 808 adult and 26 978 elderly patients were included. Female patients consisted of 42.5% and 59.3% in adult and elderly, respectively. 42 (.2%) adults died, of which 50% were female and 125 (.5%) elderly patients died, of which 60% were female. Mean (SD) age of the adult patients was 47.8 (11) years and in elderly patients was 78.7 (8) years. 82.2% and 85.7% had internal hemorrhoids in adult and elderly patients, respectively. 9326 (36.1%) adult and 7282 (27%) elderly patients underwent an operation. In the final multivariable logistic regression model for adult patients with operation, delayed operation and invasive diagnostic procedures increased the odds of mortality, whereas in elderly patients, delayed operation and frailty index were the risk factors of mortality. In both adults and elderly with no operation, increased hospital length of stay (HLOS) significantly increased the odds of mortality, and undergoing an invasive diagnostic procedure significantly decreased the odds of mortality. Conclusion In all operated patients, increased time to operation and undergoing an invasive diagnostic procedure were the risk factors for mortality. On the other hand, in non-operated emergency hemorrhoids patients, increased age and increased HLOS were the risk factors for mortality while undergoing an invasive diagnostic procedure decreased the odds of mortality.

Background: More than 400,000 cases of ventral hernia (VH) are repaired each year in the U.S. This condition is a major problem with significant morbidly and mortality. The aim of this study was to evaluate independent predictors of in-hospital mortality for patients with a primary diagnosis of VH who were admitted emergently. Methods: Non-elderly adults (age 18-64 years) with ventral hernias that required emergency admission were analyzed using the National Inpatient Sample database, 2005-2014. Demographics, clinical data, and outcomes were collected. The relationships between mortality and predictors were assessed using a multivariable logistic regression model. Results: Overall, 48,539 patients were identified. The mean (SD) age for both males and females was 50 (9.6). Overall mortality was low (316 or 0.7%). Males accounted for 35% of the total sample and 45% of all mortalities (p<0.001). The mean (SD) hospital length of stay (HLOS) was 4.9 (6.3) and 12.3 (20.6) days in surviving and deceased patients (p<0.001), respectively. Approximately 1.1% of surviving and 6% of deceased patients had gangrene (p<0.001). Intestinal obstruction was observed in 70% of surviving and 83% of deceased patients (p<0.001). While a vast majority of the patients (40,602) were operated on, 8,023 patients were not; 0.7% and 0.4% died, respectively. The mean (SD) HLOS was 5.30 (6.99) days in patients who underwent an operation and 2.97 (2.96) days in those who did not (P<0.0001). Time to operation was 0.81 (1.92) days in surviving and 1.34 (2.42) days in deceased patients (p<0.001). In the final multivariable regression model for patients who underwent an operation, age, male sex, presence of gangrene or obstruction, and longer time to operation were the main risk factors for mortality. For patients who did not undergo an operation, only HLOS and presence of obstruction were the main risk factors for mortality. Conclusion: Male sex, presence of gangrene or obstruction at the presentation, and delayed operation were shown to be risk factors for mortality in adult patients with ventral hernia admitted emergently.

Background and Objectives: Due to COVID-19, residency programs could not conduct in-person interviews during the 2020-2021 match and were forced to implement a virtual format. We conducted a nationwide survey of US senior medical students to evaluate their perception of the virtual interview process and to solicit their recommendations for future virtual interview best practices. Methods: This study was administered to US fourth-year medical students currently participating in the residency match using Survey Monkey during March 2021. Students were contacted through their respective student affairs deans. Surveys solicited demographic information, 26 4-point Likert-scale questions, and four free-response questions. Results: A total of 357 surveys were completed. Most respondents stated that they could confidently represent themselves to the program (71.7%) using a virtual platform. However, only 11.6% stated that they could confidently assess a program’s facility using a virtual platform. Although most respondents (58.26%) found that virtual meet and greets helped them better assess their fit for the program, less than half (46%) confidently believed they could assess their fit into the program after the conclusion of the virtual interview. Regarding potential disparities introduced by virtual interviews, 40.6% believed that the virtual interviews introduce greater inequalities into the match process. Two-thirds of respondents (239, 66.95%), believed that there should be a limit on the number of interview offers an applicant can accept, with the maximum number of interviews per specialty capped at 25.7 (10-150). Finally, just over two-thirds (69.47%), claimed they could confidently prepare their rank-order list at the conclusion of the interview. Conclusions: Most respondents found virtual interviews financially beneficial, however difficulty in assessing fit was a challenge. Best practice recommendations from the respondents include shorter interviews, more engaging resident-led social hours without faculty present, and preinterview packages to include video representations of the program facilities.

Background: Colorectal cancer, among which are malignant neoplasms of the rectum and rectosigmoid junction, is the fourth most common cancer cause of death globally. The goal of this study was to evaluate independent predictors of in-hospital mortality in adult and elderly patients undergoing emergency admission for malignant neoplasm of the rectum and rectosigmoid junction. Methods: Demographic and clinical data were obtained from the National Inpatient Sample (NIS), 2005–2014, to evaluate adult (age 18–64 years) and elderly (65+ years) patients with malignant neoplasm of the rectum and rectosigmoid junction who underwent emergency surgery. A multivariable logistic regression model with backward elimination process was used to identify the association of predictors and in-hospital mortality. Results: A total of 10,918 non-elderly adult and 12,696 elderly patients were included in this study. Their mean (standard deviation (SD)) age was 53 (8.5) and 77.5 (8) years, respectively. The odds ratios (95% confidence interval, P-value) of some of the pertinent risk factors for mortality for operated adults were 1.04 for time to operation (95%CI: 1.02–1.07, p < 0.001), 2.83 for respiratory diseases (95%CI: 2.02–3.98), and 1.93 for cardiac disease (95%CI: 1.39–2.70), among others. Hospital length of stay was a significant risk factor as well for elderly patients—OR: 1.02 (95%CI: 1.01–1.03, p = 0.002). Conclusions: In adult patients who underwent an operation, time to operation, respiratory diseases, and cardiac disease were some of the main risk factors of mortality. In patients who did not undergo a surgical procedure, malignant neoplasm of the rectosigmoid junction, respiratory disease, and fluid and electrolyte disorders were risk factors of mortality. In this patient group, hospital length of stay was only significant for elderly patients.

Background: Tracheostomy is a procedure commonly conducted in patients undergoing emergency admission and requires prolonged mechanical ventilation. In the present study, the aim was to determine the prevalence and risk factors of mortality among emergently admitted patients with tracheostomy complications, during the years 2005–2014. Methods: This was a retrospective cohort study. Demographics and clinical data were obtained from the National Inpatient Sample, 2005–2014, to evaluate elderly (65+ years) and non-elderly adult patients (18–64 years) with tracheostomy complications (ICD-9 code, 519) who underwent emergency admission. A multivariable logistic regression model with backward elimination was used to identify the association between predictors and in-hospital mortality. Results: A total of 4711 non-elderly and 3315 elderly patients were included. Females included 44.5% of the non-elderly patients and 47.6% of the elderly patients. In total, 181 (3.8%) non-elderly patients died, of which 48.1% were female, and 163 (4.9%) elderly patients died, of which 48.5% were female. The mean (SD) age of the non-elderly patients was 50 years and for elderly patients was 74 years. The mean age at the time of death of non-elderly patients was 53 years and for elderly patients was 75 years. The odds ratio (95% confidence interval, p-value) of some of the pertinent risk factors for mortality showed by the final regression model were older age (OR = 1.007, 95% CI: 1.001–1.013, p < 0.02), longer hospital length of stay (OR = 1.008, 95% CI: 1.001–1.016, p < 0.18), cardiac disease (OR = 3.21, 95% CI: 2.48–4.15, p < 0.001), and liver disease (OR = 2.61, 95% CI: 1.73–3.93, p < 0.001). Conclusion: Age, hospital length of stay, and several comorbidities have been shown to be significant risk factors in in-hospital mortality in patients admitted emergently with the primary diagnosis of tracheostomy complications. Each year of age increased the risk of mortality by 0.7% and each additional day in the hospital increased it by 0.8%.
