Role of Empiric Anti-Fungal Therapy in the Treatment of Perforated Peptic Ulcer Disease: Review of the Evidence and Future Directions.
Background: Peptic ulcer disease (PUD) affects four million people worldwide. Perforated peptic ulcer (PPU) occurs in less than 15% of cases but is associated with significant morbidity and mortality rates. Administration of antibiotics is standard treatment for gastrointestinal perforations, including PPU. ⋯ Conclusion: The current evidence reviewed here does not demonstrate efficacy of anti-fungal agents in improving outcomes in patients with PPU. As such, we caution against the routine use of empiric anti-fungal agents in these patients. Further studies should help identify specific subpopulations of patients who might derive benefit from anti-fungal therapy and help define appropriate treatment regimens and durations that minimize the risk of resistance, adverse events, and cost.

Background: Sepsis is an uncommon occurrence after appendectomy, but the morbidity and mortality of patients who develop sepsis after appendectomy remains exceedingly high. The purpose of this study is to identify risk factors and adverse post-operative outcomes associated with sepsis after appendectomy in adults. Patients and Methods: The American College of Surgery National Surgical Quality Improvement Program participant user database was queried from 2012 to 2015. Patients who underwent appendectomy were identified and demographic data, intra-operative variables, and post-operative outcomes were collected. ⋯ Patients who developed sepsis after appendectomy were more likely to return to the operating room (24.76 vs. 0.77%, p < 0.001), be re-admitted for any cause (53.38% vs. 2.70%, p < 0.0001), and die within 30 days of surgery (5.47% vs. 0.05%, p < 0.001). Conclusion: Patients who become septic after appendectomy are at risk for adverse post-operative morbidity and mortality. Age 60 years or more, African American race, morbid obesity, acute renal failure or dialysis, disseminated malignancy, and open appendectomy increase the risk for sepsis after appendectomy and sepsis-related morbidity and mortality. Given the remarkably large number of appendectomies that are performed each year, the findings of this study can assist in identifying at-risk patients, facilitate physician-patient discussion and shared decision-making, and guide appropriate care to further reduce the incidence of sepsis after appendectomy.

Albumin/Procalcitonin Ratio Is a Sensitive Early Marker of Nosocomial Blood Stream Infection in Patients with Intra-Cerebral Hemorrhage.
Background: This study was performed to investigate the combination of admission serum procalcitonin (PCT) and albumin (alb) concentrations as a diagnostic predictor for discriminating patients with nosocomial blood stream infection (BSI) among those with spontaneous intra-cerebral hemorrhage (ICH). Methods: We conducted a retrospective study on patients with ICH and hospital-acquired BSI. Clinical and microbiological data were compared in patients who experienced nosocomial BSI during a hospital stay and those who did not. Multivariable logistic regression analyses were used to identify independent risk factors for nosocomial BSI. ⋯ In the subgroup of 85 patients with nosocomial BSI, the albumin:PCT ratio in patients with shock was lower than that in those without shock (7.154 [2.975-26.267] vs 28.000 [3.818-57.812]; p = 0.027). Conclusion: The albumin:PCT ratio can be used as an early diagnostic predictor for nosocomial BSI in patients with ICH. Additionally, BSI patients with lower albumin:PCT ratios are more likely to experience shock. The albumin:PCT ratio is expected to be a rapid and low-cost tool for clinical practice.

Clinical Outcome and Risk Factors for Emergency Department Adult Patients with Thoracic Empyema after Video-Assisted Thoracic Surgical Procedure.
Background: Empyema is a purulent infection of the pleural cavity that is most relevant to parapneumonia effusion. Video-assisted thoracoscopic surgery (VATS) is an option for stage 2 (fibrinopurulent) and stage 3 (organizational). Surgeons may see critically ill patients with pleural empyema who present to the emergency department (ED). ⋯ Two groups (survivors and non-survivors) significantly differed in age (p = 0.013), sex (p = 0.026), comorbidity (p = 0.017), cough (p = 0.024), chest pain (p = 0.016), serum hemoglobin (p = 0.001), and potassium (p = 0.004) levels. Further logistic regression analysis showed statistically significant differences in age, hemoglobin levels, and potassium levels. Conclusion: Among the ED patients with thoracic empyema, older age, lower hemoglobin levels, and higher potassium levels are associated with post-operative death after VATS. These findings underline the importance of careful peri-operative treatment in older patients with signs of empyema when they present to the ED.

Artificial Intelligence Methods for Surgical Site Infection: Impacts on Detection, Monitoring, and Decision Making.
Background: There has been tremendous growth in the amount of new surgical site infection (SSI) data generated. Key challenges exist in understanding the data for robust clinical decision-support. Limitations of traditional methodologies to handle these data led to the emergence of artificial intelligence (AI). ⋯ Discussions on opportunities, challenges, and limitations of applying these methods to derive accurate SSI prediction are provided. Results: Four main challenges in dealing with SSI data were defined: (1) complexities in using SSI data, (2) disease knowledge, (3) decision support, and (4) heterogeneity. The implications of some of the recent advances in AI methods to optimize clinical effectiveness were discussed. Conclusions: Artificial intelligence has the potential to provide insight in detecting and decision-support of SSI. As we turn SSI data into intelligence about the disease, we increase the possibility of improving surgical practice with the promise of a future optimized for the highest quality patient care.
