COVID-19 is a new disease, based on currently available limited information, older adults and people of any age who have severe underlying medical conditions may be at higher risk for severe illness from COVID-19. People of all age groups are also at risk. Healthcare providers have always been the professionals most exposed to the risk of contracting to any kind of infection due to the nature of their profession. Elective interventions have been postponed to give care of patients with COVID-19. However, some interventions cannot be delayed, such as trauma surgery, acute abdomen, and emergency endoscopies. To maintain the sustainability of the healthcare system, the protection of healthcare providers should be the top priority. On the other hand, patients, who need emergency healthcare, should also be provided with appropriate treatment. Healthcare professionals should choose a treatment method appropriately in the circumstances to protect themselves and their patients as much as possible. This paper aims to summarize how a surgeon may act appropriately when an intervention is inevitable during the COVID-19 pandemic.

Background Cytomegalovirus (CMV) and BK virus (BKV) are post-transplant opportunistic viral infections that affect patient and graft survival. This study was designed to evaluate the risk of BKV nephropathy and CMV disease in kidney transplant recipients who received induction therapy with ATG or basiliximab. Material/Methods We retrospectively analyzed information on 257 adult patients who underwent kidney transplantation between January 2007 and 2017. Patients were categorized into 3 groups according to the induction therapies . The primary endpoint was the onset of CMV disease or biopsy-confirmed BKV nephropathy. The secondary endpoints were biopsy-proven rejection episodes, graft loss, loss to follow-up, and death. Results We followed 257 patients for a median of 55.5 months. The incidence of CMV disease was significantly higher in the only ATG group compared to the group without induction treatment (p<0.001). There was no significant difference in the incidence of BKV nephropathy among groups (p>0.05). The dosage of ATG (OR, 10.685; 95% CI, 1.343 5 to 85.009; P=0.025) was independent risk factor for death. Conclusions This study demonstrated that a higher dosage of ATG in high-risk patients is associated with an increased risk of CMV disease and patient death, also, reducing the dosage may be a rational strategy for increasing graft and patient’s survival.

Background: The incidence of underlying malignancy in appendicitis ranges between 0.5% and 1.7%. We sought to identify the subset of patients with appendicitis who are at increased risk of appendiceal malignancy. Methods: Using the Eastern Association for the Surgery of Trauma Multicenter Study of the Treatment of Appendicitis in America: Acute, Perforated, and Gangrenous database, we included all patients from 28 centers undergoing immediate, delayed, or interval appendectomy between 2017 and 2018. Univariate then multivariable analyses were performed to compare patients with and without malignancy and to identify independent demographic, clinical, laboratory, and/or radiological predictors of malignancy. Akaike information criteria for regression models were used to evaluate goodness of fit. Results: A total of 3,293 patients were included. The median age was 38 (27e53) years, and 46.5% were female patients. On pathology, 48 (1.5%) had an underlying malignancy (adenocarcinoma [60.4%], neuroendocrine [37.5%], and lymphoma [2.1%]). Patients with malignancy were older (56 [34.5e67] vs 37 [27e52] years, P < .001), had longer duration of symptoms before presentation (36e41 vs 18e23 hours, P ¼ .03), and were more likely to have a phlegmon on imaging (6.3% vs 1.3%, P ¼ .03). Multivariable analyses showed that an enlarged appendiceal diameter was independently associated with malignancy (odds ratio ¼ 1.06, 95% confidence interval ¼ 1.01e1.12; P ¼ .01). The incidence of malignancy in patients >40 years with an appendiceal diameter >10 mm on computed tomography was 2.95% compared with 0.97% in patients 40 years old with appendiceal diameter 10 mm. The corresponding risk ratio for that population was 3.03 (95% confidence interval: 1.24e7.42; P ¼ .02). Conclusion:The combination of age >40 and an appendiceal diameter >10 mm is associated with a greater than 3-fold increased risk of malignancy in patients presenting with appendicitis.
