RESUMO
AIM: This study investigated the effects of the antioxidant agents, ozone (O) and ellagic acid (EA), on ischemia/reperfusion (I/R) injuries developed from an ovarian torsion-detorsion model. MATERIALS AND METHODS: Arteries in the left ovaries of rats were clamped for two hours to achieve torsion, and then the clamps were removed for a two-hour detorsion period. Thirty-five female Sprague-Dawley rats were randomly divided into five groups: control: administered only with anesthesia, rats were not subjected to torsion-detorsion; I/R: subjected to torsion and subsequent detorsion, without administering any treatment agent; and I/R + EA, I/R + O and I/R + O + EA: subjected to torsion and detorsion processes and administered with EA, O or EA + O at the 75th minute of torsion. The rats were then sacrificed under general anesthesia and the ovarian tissues were excised. The tissues were homogenized and levels of glutathione reductase, catalase, superoxide dismutase and malondialdehyde (MDA) were analyzed. Tissue damage was evaluated in terms of histopathological parameters, such as hemorrhage, congestion, edema and inflammation. RESULTS: Antioxidant enzyme activity and MDA levels in the ovary tissue increased in the I/R group and decreased in the O, EA and O + EA groups (P < 0.05). Histopathological examination revealed that tissue damage in the O, EA and O + EA groups decreased in comparison with the I/R group (P < 0.05). CONCLUSIONS: These biochemical and histopathological findings suggest that EA and O are effective against ovarian I/R injury.

Immunocompromised patients are a heterogeneous and diffuse category frequently presenting to the emergency department with acute surgical diseases. Diagnosis and treatment in immunocompromised patients are often complex and must be multidisciplinary. Misdiagnosis of an acute surgical disease may be followed by increased morbidity and mortality. Delayed diagnosis and treatment of surgical disease occur; these patients may seek medical assistance late because their symptoms are often ambiguous. Also, they develop unique surgical problems that do not affect the general population. Management of this population must be multidisciplinary.This paper presents the World Society of Emergency Surgery (WSES), Surgical Infection Society Europe (SIS-E), World Surgical Infection Society (WSIS), American Association for the Surgery of Trauma (AAST), and Global Alliance for Infection in Surgery (GAIS) joined guidelines about the management of acute abdomen in immunocompromised patients.

Appropriate measures of infection prevention and management are integral to optimal clinical practice and standards of care. Among surgeons, these measures are often over-looked. However, surgeons are at the forefront in preventing and managing infections. Surgeons are responsible for many of the processes of healthcare that impact the risk for surgical site infections and play a key role in their prevention. Surgeons are also at the forefront in managing patients with infections, who often need prompt source control and appropriate antibiotic therapy, and are directly responsible for their outcome. In this context, the direct leadership of surgeons in infection prevention and management is of utmost importance. In order to disseminate worldwide this message, the editorial has been translated into 9 different languages (Arabic, Chinese, French, German, Italian, Portuguese, Spanish, Russian, and Turkish).

The trauma mortality rate is higher in the elderly compared with younger patients. Ageing is associated with physiological changes in multiple systems and correlated with frailty. Frailty is a risk factor for mortality in elderly trauma patients. We aim to provide evidence-based guidelines for the management of geriatric trauma patients to improve it and reduce futile procedures. Six working groups of expert acute care and trauma surgeons reviewed extensively the literature according to the topic and the PICO question assigned. Statements and recommendations were assessed according to the GRADE methodology and approved by a consensus of experts in the field at the 10th international congress of the WSES in 2023. The management of elderly trauma patients requires knowledge of ageing physiology, a focused triage, including drug history, frailty assessment, nutritional status, and early activation of trauma protocol to improve outcomes. Acute trauma pain in the elderly has to be managed in a multimodal analgesic approach, to avoid side effects of opioid use. Antibiotic prophylaxis is recommended in penetrating (abdominal, thoracic) trauma, in severely burned and in open fractures elderly patients to decrease septic complications. Antibiotics are not recommended in blunt trauma in the absence of signs of sepsis and septic shock. Venous thromboembolism prophylaxis with LMWH or UFH should be administrated as soon as possible in high and moderate-risk elderly trauma patients according to the renal function, weight of the patient and bleeding risk. A palliative care team should be involved as soon as possible to discuss the end of life in a multidisciplinary approach considering the patient's directives, family feelings and representatives' desires, and all decisions should be shared. The management of elderly trauma patients requires knowledge of ageing physiology, a focused triage based on assessing frailty and early activation of trauma protocol to improve outcomes. Geriatric Intensive Care Units are needed to care for elderly and frail trauma patients in a multidisciplinary approach to decrease mortality and improve outcomes.

Despite evidence supporting the effectiveness of best practices of infection prevention and management, many surgeons worldwide fail to implement them. Evidence-based practices tend to be underused in routine practice. Surgeons with knowledge in surgical infections should provide feedback to prescribers and integrate best practices among surgeons and implement changes within their team. Identifying a local opinion leader to serve as a champion within the surgical department may be important. The "surgeon champion" can integrate best clinical practices of infection prevention and management, drive behavior change in their colleagues, and interact with both infection control teams in promoting antimicrobial stewardship.
