Background: Violence at school is broadly defined as a range of acts including physical, psychological, and sexual violence, as well as bullying. These can occur at school, in the school environment, on the way to school, or in any school-related environment. Considering the school environment as the place where a child spends most of their daily life, its impact on the child's life cannot be underestimated. This study aims to contribute to the literature by sharing characteristics of school violence and bullying cases with forensic reports prepared in our department, and by presenting solution suggestions for detecting and preventing these issues.

Methods: Between January 1, 2012 and December 31, 2022, a total of 14,330 forensic reports issued by the Dokuz Eylül University Faculty of Medicine, Department of Forensic Medicine, were analyzed. It was found that 125 cases involved school violence. Five cases involving non-students were excluded, leaving 120 student cases for inclusion in the study. Sociodemographic data, type of violence, incident location, educational stage, injury origin, and psychiatric assessment results were assessed. Statistical analysis of the data was performed using the SPSS 29.0 package.

Results: Of the 120 cases analyzed, 90 (75%) were male, and 30 (25%) were female. The cases were most frequently subjected to violence at the secondary education stage (n=73, 60.8%) and, secondarily, at the primary education stage (n=36, 30%). When the type of violence was analyzed, it was found that physical violence was the most common (n=96, 80%), followed by sexual violence (n=21, 17.5%). Among these, 91.1% (n=82) of males and 43.3% (n=13) of females were exposed to physical and sexual violence, respectively. A statistically significant relationship was found between the type of violence and gender (p<0.001). Post-traumatic stress disorder (PTSD) was the most common diagnosis among those who underwent psychiatric assessments after experiencing violence (n=15, 45.5%).

Conclusion: To effectively combat violence and bullying, we believe that strategies based on analyzing the causes of bullying in schools across different cultures, planning and implementing appropriate interventions tailored to the problem area, and preventing recurrence by disseminating the results will yield more effective outcomes.

Background: Various factors contribute to the development of mortality and morbidity in hip fracture surgeries. This study aims to investigate the effects of modifiable factors such as the type of anesthesia, anesthesia management, surgical method, and timing of surgery on 30-day mortality rates, intensive care unit admissions, and complications.

Methods: A total of 400 patients who underwent hip fracture surgery between January 2021 and December 2023 at a Training and Research Hospital were retrospectively analyzed. Patients were divided into two groups: those followed in the ward, named Group 1 (n=304), and those in the intensive care unit, named Group 2 (n=96). Recorded data included demographic characteristics, American Society of Anesthesiologists (ASA) physical status scores, types of comorbidities, anesthesia type, surgical method, surgical delay time, duration of surgery, blood transfusion requirements, and complications.

Results: Patients in Group 2 had higher mean age, comorbidity, and mortality rates compared to Group 1 (p<0.001). In terms of types of comorbidities, the rate of intensive care unit admission was higher in patients with coronary artery disease and chronic renal failure (p<0.001). Mean surgical delay and length of hospital stay were also higher in Group 2 (p<0.001). In multivariate logistic regression analysis, age (p<0.001, Odds Ratio [OR]=1.91, Confidence Interval [CI]=1.046-1.137), ASA score (p<0.001, OR=3.872, CI=1.913-7.838), duration of surgical delay (p<0.001, OR=2.029, CI=1.365-3.017), surgical method (p=0.003, OR=2.003, C=1.258-3.188), and length of hospital stay (p=0.006, OR=1.147, CI=1.04-1.266) were determined as predictive factors for 30-day mortality.

Conclusion: This study found that age, ASA classification, length of hospital stay, surgical method, and surgical delay were predictive factors for both morbidity and mortality. Among these, surgical delay time appears to be a modifiable parameter when all factors are considered.

Background: The aim of our study is to assess the prognostic impact of the neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), and platelet-to-lymphocyte ratio (PLR) on 28-day mortality in patients admitted to the intensive care unit with crush syndrome following the Kahramanmaraş earthquake in Türkiye.

Methods: A total of 63 adult patients with crush syndrome admitted to the intensive care unit after the earthquake were enrolled in this study. The medical records of the patients were examined using follow-up forms and the hospital data system.

Results: The mean age of the patients was 38.9±17.3 years, and the median time under debris was 31.5 hours. The 28-day mortality rate was 27%. In univariate generalized estimating equations (GEE) and other analyses, variables that are significant (or candidate variables) between 28-day mortality groups included age as a biological factor. These variables were included in the multivariate GEE model. The effects of continuous renal replacement therapy (CRRT), serum sodium concentration, Sequential Organ Failure Assessment (SOFA) score, and PLR on mortality were statistically significant.

Conclusion: Elevated SOFA scores, the necessity for CRRT, increased serum sodium levels, and decreased PLR values are associated with increased 28-day mortality in patients with crush syndrome after an earthquake.

Background: This study explored the potential of non-contrast thoracic computed tomography (CT) to predict anemia by correlating CT parameters with hemoglobin (Hb) levels in patients who underwent non-contrast thoracic CT for various indications.

Methods: This retrospective study included 150 patients who underwent non-contrast thoracic CT scans and complete blood counts within 24 hours at our center between January and June 2023. Exclusion criteria included acute bleeding, iron accumulation disorders, recent transfusions, pregnancy, and certain thoracic CT artifacts. Hounsfield Unit (HU) measurements were obtained from the ascending aorta, left ventricular cavity, and descending aorta, and compared with Hb and hematocrit (Htc) values. Anemia indicators such as the 'Aortic Ring Sign (ARS)' and the 'Hyperdense Septum Sign (HSS)' were also evaluated.

Results: Anemic patients (48%) exhibited significantly lower HU measurements at all three CT scan locations and higher instances of ARS and HSS compared to non-anemic patients. Notably, the presence of HSS and ARS was strongly associated with anemia. Thresholds for HU measurements corresponding to anemia were determined using receiver operating characteristic curve analysis, which also revealed strong positive correlations between HU measurements and Hb/Htc levels.

Conclusion: The study concludes that non-contrast thoracic CT parameters, particularly HU measurements and the presence of ARS and HSS, are significantly associated with anemia. These CT indicators could serve as reliable, non-invasive markers for predicting anemia in patients, potentially aiding in the early diagnosis and management of the condition.

Background: This study aimed to develop and validate an artificial intelligence model using machine learning (ML) to predict hospital mortality in patients with acute mesenteric ischemia (AMI).

Methods: A total of 122 patients diagnosed with AMI at Sakarya University Training and Research Hospital between January 2011 and June 2023 were included in the study. These patients were divided into a training cohort (n=97) and a validation cohort (n=25), and further categorized as survivors and non-survivors during hospitalization. Serum-based laboratory results served as features. Hyperfeatures were eliminated using Recursive Feature Elimination (RFE) in Python to optimize outcomes. ML algorithms and data analyses were performed using Python (version 3.7).

Results: Of the patients, 56.5% were male (n=69) and 43.5% were female (n=53). The mean age was 71.9 years (range 39-94 years). The mortality rate during hospitalization was 50% (n=61). To achieve optimal results, the model incorporated features such as age, red cell distribution width (RDW), C-reactive protein (CRP), D-dimer, lactate, globulin, and creatinine. Success rates in test data were as follows: logistic regression (LG), 80%; random forest (RF), 60%; k-nearest neighbor (KN), 52%; multilayer perceptron (MLP), 72%; and support vector classifier (SVC), 84%. A voting classifier (VC), aggregating votes from all models, achieved an 84% success rate. Among the models, SVC (sensitivity 1.0, specificity 0.77, area under the curve (AUC) 0.90, Confidence Interval (95%): (0.83-0.84)) and VC (sensitivity 1.0, specificity 0.77, AUC 0.88, Confidence Interval (95%): (0.83-0.84)) were noted for their effectiveness.

Conclusion: Independent risk factors for mortality were identified in patients with AMI. An efficient and rapid method using various ML models to predict mortality has been developed.

Background: Open reduction and internal fixation (ORIF) using locking plates is a widely adopted treatment for displaced proximal humerus fractures. Various augmentation techniques have been developed to enhance the stability of plate fixation. Among these, iliac bone autograft is notable for its advantages over allografts, such as ready availability and the elimination of costs and risks associated with disease transmission. Despite its potential benefits, data on the outcomes of iliac bone autograft augmentation (IBAA) are still limited. This study aims to present the mid- to long-term results of treating proximal humerus fractures with ORIF using locking plates and IBAA.

Methods: The study included 15 patients treated with ORIF and IBAA. We classified fracture patterns using the Neer classification and estimated local bone density via the deltoid tuberosity index. We measured the neck shaft angle (NSA) and humeral head height (HHH) on both immediate postoperative and most recent X-ray images to assess the maintenance of reduction. Clinical outcomes were evaluated using the DASH (Disabilities of the Arm, Shoulder, and Hand) and Constant scores.

Results: The average follow-up duration was 59.56 months, ranging from 24 to 93 months. A majority of fractures were classified as four-part (53%). The average immediate and late postoperative NSAs were 132.6±8.19 and 131.6±7.32 degrees, respectively. The average HHH on the immediate postoperative and latest follow-up images were 16.46±6.07 and 15.10±5.34, respectively. None of the patients exhibited any radiological signs of avascular necrosis or loss of reduction at the latest follow-up. The mean postoperative Constant and DASH scores at the latest follow-up were 79.6 and 11.5, respectively.

Conclusion: Our findings suggest that ORIF with IBAA is an effective method for managing three- or four-part proximal humerus fractures, yielding excellent outcomes.

Background: Acute appendicitis (AA) is the primary cause of acute abdomen in patients presenting to the emergency department with abdominal pain. Limited studies have explored the relationship between serum hepcidin levels and AA. This study aimed to measure serum hepcidin levels in patients undergoing surgery with a preliminary diagnosis of AA and to assess whether these levels can serve as a biochemical marker for diagnosing AA.

Methods: This study included patients aged 18 or older who presented to the emergency department between April 2018 and May 2019 and underwent surgery with a diagnosis of AA. The cohort comprised 94 patients with surgical pathology results compatible with AA (Group A), 16 patients with results not compatible with AA (Group B), and 42 healthy controls. Serum hepcidin levels were measured from venous blood samples.

Results: Mean hepcidin levels were 1750±285 pg/mL in Group A, 1349±381 pg/mL in Group B, and 1066±225 pg/mL in the control group. Statistically significant differences in serum hepcidin levels were observed between Group A and the control group (p<0.05).

Conclusion: Hepcidin levels were significantly higher in patients with AA compared to both the control group and patients with surgically confirmed non-AA pathology. Therefore, hepcidin may serve as a useful adjunct in diagnosing acute appendicitis.

Background: This study investigates the effects of hydroxychloroquine (HCQ) on a sepsis-induced acute respiratory distress syndrome (ARDS) model in rats, initiated by a fecal intraperitoneal injection procedure (FIP).

Methods: Three groups were established: control (n=8), FIP + saline (n=7), and FIP + HCQ (20 mg/kg/day) (n=9). Blood samples were collected for arterial blood gas and biochemical analyses, and bilateral pneumonectomy was performed for histopathologic examination.

Results: In the FIP + saline group, PaO2 decreased and PaCO2 increased, whereas these levels normalized in the FIP + HCQ group compared to the control (p<0.001 and p<0.05, respectively). Histopathological scores for alveolar congestion, perivascular/interstitial edema, hemorrhage in alveolar tissue, leukocyte infiltration or aggregation in air spaces/vascular walls, and alveolar wall/hyaline membrane thickness increased in the FIP + saline group compared to the control group (p<0.01). These scores decreased in the FIP + HCQ group compared to the FIP + saline group (p<0.01). HCQ reversed the sepsis-induced increase in malondialdehyde, tumor necrosis factor-alpha, interleukin-6, and lactic acid.

Conclusion: HCQ may be an effective and safe option to mitigate the severe progression of ARDS.

Background: Post-ischemia reperfusion can lead to oxidative stress and an increase in oxidative markers. Employing preventive strategies and antioxidant agents may help mitigate ischemia-reperfusion injury (IRI). The use of a tourniquet in extremity surgery has been associated with IRI. This study aims to investigate the impact of three different approaches- brachial plexus block, total intravenous anesthesia (TIVA), and inhalation anesthesia-on IRI during upper extremity surgery using a tourniquet.

Methods: Patients aged 18 to 45 with American Society of Anesthesiologists (ASA) I-II scores were randomly assigned to one of three groups: Group A received an axillary block with bupivacaine; Group I underwent inhalation anesthesia with sevoflurane; and Group T received TIVA with propofol and remifentanil infusion. Blood samples were collected to measure glucose, lactate, total anti-oxidant status (TAS), total oxidant status (TOS), and ischemia-modified albumin (IMA) levels at various time points: before anesthesia (t1), 1 minute before tourniquet release (t2), 20 minutes after tourniquet release (t3), and 4 hours after tourniquet release (t4).

Results: In Group I, lactate levels at t3, and glucose levels at t2 and t3, were higher compared to the other groups. Group A exhibited lower IMA levels at t2, t3, and t4 than the other groups. Additionally, Group I had lower IMA levels at t2, t3, and t4 compared to Group T. TAS levels were higher in Group I at t2, t3, and t4 compared to the other groups. TOS levels at t2 and t3 were lower in Group A than in Group I.

Conclusion: Axillary anesthesia results in a sympathetic block, promoting better perfusion of the upper extremity. This study demonstrated lower levels of oxidative stress markers with axillary plexus block. Therefore, these results suggest that the axillary block has the potential to mitigate IRI.

Background: Traumatic liver injury is an acute event that triggers liver repair. The augmenter of liver regeneration (ALR) has been identified as a growth factor involved in this process. This study evaluates the impact of ALR on isolated liver blunt trauma and examines its relationship with various time intervals.

Methods: Forty healthy female Wistar albino rats were divided into five groups (n=8 each). Isolated blunt liver trauma was induced using a custom-designed trauma platform in all groups except for Group 1. The groups were categorized by the timing of euthanasia post-trauma: 2nd (15 minutes), 3rd (30 minutes), 4th (45 minutes), and 5th (60 minutes). Assessments included plasma ALR levels, liver tissue ALR levels (both intact and lacerated), biochemical indices, and liver histological analysis.

Results: Plasma ALR levels in Group 4 were higher than in Groups 1 and 2 (p<0.01). Intact liver ALR levels in Groups 3 and 4 exceeded those in Group 1 (p<0.05, p<0.01, respectively). Intact liver tissue ALR levels in Group 5 were lower than in Groups 3 and 4 (p<0.05, p<0.01, respectively). Lacerated liver tissue ALR levels in Group 5 were higher than those in Groups 2 and 3. In Group 1, the plasma ALR level was higher than the intact liver tissue ALR level (p<0.05). In Group 2, plasma ALR levels exceeded those in intact liver tissue ALR levels (p<0.01). In Group 3, plasma ALR levels surpassed both lacerated and intact liver tissue ALR levels (p<0.05, p<0.001, respectively). In Group 4, the plasma ALR level was higher than the intact liver tissue ALR level (p<0.01), and the lacerated liver tissue level was higher than the intact liver ALR level (p<0.001). Additionally, inflammation scores were higher in Groups 3, 4, and 5 compared to Group 2 (p<0.05, p<0.01, p<0.01, respectively).

Conclusion: This study is the first to explore the role of ALR in isolated blunt liver trauma. Following blunt liver trauma, both plasma and liver tissue ALR levels change within minutes.
