The World Health Organization (WHO) Central Nervous System (CNS) Tumors Classification 5^th edition (2021) integrates both molecular and histopathological criteria for diagnosing glial tumors. This updated classification highlights significant differences between pediatric and adult gliomas in terms of molecular characteristics and prognostic implications. The 5^th edition comprises a new category of pediatric-type diffuse low-grade glioma (PDLGG) and pediatric-type diffuse high-grade glioma (PDHGG), classified mainly based on genetic alterations and histopathological features. We reviewed the microscopy, diagnostic molecular pathology, and prognosis of various tumors under the categories PDLGG and PDHGG. The review also addresses the need for clarification concerning overlapping diagnostic features. PDLGG are characterized by diffuse growth, low-grade morphology, and MYB/MYBL1(MYB Proto-Oncogene Like 1) gene fusion or mitogen-activated protein kinase (MAPK) pathway alterations. In contrast, PDHGG is described by diffuse growth, high-grade morphology, and increased mitosis and often shows alterations of histone gene resulting in epigenetic alterations, which contrasts with common isocitrate dehydrogenase (IDH) mutation and epidermal growth factor receptor (EGFR) amplification seen in adult-type high-grade glioma.

Sarcopenia, first introduced as a concept by I. Rosenberg in 1989, has since been extensively studied, particularly in its correlation with chronic diseases. In recent years, sarcopenia has been increasingly associated with advanced chronic liver disease, leading to a lower quality of life and poor outcomes for these patients. Studies have shown that sarcopenia has a prevalence of 33% in individuals with advanced chronic liver disease, impacting not only the patient's health but also contributing to increased healthcare costs. The prevalence of frailty in patients with advanced chronic liver disease is 27%. Given the high prevalence of sarcopenia and frailty in this population, early diagnosis and treatment are crucial to improving patient quality of life outcomes and reducing the strain on healthcare systems globally.

Bullying in schools is a serious global health issue that jeopardizes youth and future adult health and negatively impacts academic outcomes. This cross-sectional study investigated the prevalence, forms, and associated factors of bullying among students aged 7-17 in public schools in Shaqra City, Saudi Arabia, where no prior data existed. A total of 372 students participated, with a median age of 11 years (interquartile range 9-14), of whom 187 were girls. 27 students (12.6%) reported being bullied in the past month, primarily through verbal abuse (89.4%), followed by physical bullying (10.6%). Cyberbullying was prevalent, with all students bullied experiencing it through social media, and some through texting (6 students, 1.6%) or email (3 students, 0.8%). Factors like student and parent age, student sex, school level, class level, nationality, chronic diseases, polygamy, and smartphone ownership were not associated with bullying. Cyberbullying and bullying affected 12.6% of students. Verbal bullying, the most common, occurred in restrooms and halls. Victims were hesitant to discuss their worries with anyone. Bullying incidents both within and outside of schools were more likely to result in positive adult intervention. Bullying among adolescents was attributed to factors such as physical strength and size. The possible reactions of bystander peers to a bullying incident include alerting the school administration and directly intervening independently.

Cardiovascular disease remains a leading cause of morbidity and mortality worldwide. Understanding and detecting risk factors are crucial for early diagnosis and prevention strategies. Obesity, dyslipidemia, hypertension, and insulin resistance, among others, have been described as modifiable risk factors. Among these, the triglycerides-to-HDL cholesterol (TG/HDL) ratio has been described as a marker of insulin resistance and a predictor of cardiovascular disease. Our objective was to investigate the association between the TG/HDL ratio and various cardiometabolic risk factors. A total of 239 young adults aged 18-24 years were recruited. We assessed anthropometric measurements, lipid profiles, glucose levels, insulin, the HOMA index, and the TG/HDL ratio. Participants were stratified based on their BMI and TG/HDL ratio. Our findings revealed that individuals with an elevated TG/HDL ratio had higher blood pressure, BMI, waist circumference, cholesterol, and triglyceride levels compared to those with a normal ratio. Specifically, the TG/HDL ratio was associated with an odds ratio (OR) of 9.3 for overweight, 27.5 for obesity, and 4.41 for abdominal obesity. Additionally, the HOMA index, which measures insulin resistance, was higher in those with an elevated TG/HDL ratio, with a prevalence of 45.6%. In conclusion, the TG/HDL ratio is a predictive marker of insulin resistance in young individuals and is associated with modifiable risk factors for cardiometabolic disease.

Armed conflict is a prevalent global issue that affects both the socioeconomic aspects of society and has profound psychological consequences for those directly involved. This cross-sectional comparative study explored the impact of armed conflict on the self-esteem of nursing students in Sudan and Saudi Arabia. In total, 308 nursing students provided data. The Rosenberg Self-Esteem Scale (RSES) was used to evaluate nursing students' self-esteem. The findings demonstrated that nursing students who were exposed to armed conflict had lower self-esteem than those who were not. However, based on sex, marital status, and age, no statistically significant differences were observed in the nursing students' self-esteem. The current findings indicate that nursing students exposed to armed conflict have low self-esteem. Interventions providing mental health support are essential for improving their self-esteem. Further research should explore other factors that could impact the self-esteem of nursing students.

Cardiovascular complications represent a significant health concern for individuals with diabetes mellitus. The relationship between diabetes and cardiovascular diseases is complex and multifaceted, involving a variety of pathophysiological mechanisms. This study aimed to investigate the potential role of the cardiothoracic ratio as a prognostic tool for cardiovascular disorders in patients with diabetes. A retrospective case-control study of 530 adult patients referred to a tertiary care hospital in Saudi Arabia was conducted. Medical records, including chest X-rays, were analyzed to determine the cardiothoracic ratio. Patients diagnosed with diabetes who experienced cardiac disorders had significantly higher cardiothoracic ratios compared to patients with diabetes alone and controls. HbA1c was significantly elevated among patients with diabetes and cardiovascular disorders (mean = 71.5 ± 25.43 mmol/mol) compared to the other patients. There was a significant positive correlation between the duration of diabetes and the cardiothoracic ratio (r = 0.64, P < 0.001). Furthermore, the cardiothoracic ratio above 0.51 was a good discriminator of cardiovascular disorders in patients with diabetes, with an area under the curve of 0.737, sensitivity of 97.1%, and specificity of 87.2%. This study provided comprehensive evidence supporting the association between cardiothoracic ratio and subsequent cardiovascular adverse outcomes in patients with diabetes. We recommend adopting the cardiothoracic ratio as a valuable prognostic tool for risk stratification among people with diabetes.

This study aimed to identify and analyze factors associated with a higher risk of 3-year mortality in patients with Parkinson's disease (PD) within a Romanian cohort, focusing on individuals with more advanced disease stages as indicated by the Hoehn and Yahr scale. We conducted a cross-sectional observational study on 42 patients with PD treated at the Neurology Clinic I, Cluj-Napoca County Emergency Clinical Hospital, between October 2019 and January 2021. All participants were at stages 2.5 or 3 on the Hoehn and Yahr scale at baseline. Various clinical, neuropsychological, and neurophysiological assessments were performed, including evaluations for motor and non-motor symptoms such as anhedonia (via the Snaith-Hamilton Pleasure Scale - SHAPS) and cognitive impairment. The use of antiparkinsonian medications and antidepressants was also recorded. Factors associated with higher mortality risk included a higher anhedonia score (SHAPS > 34; P = 0.03), higher levodopa doses (cutoff = 937.5 mg; P = 0.001), and the administration of mirtazapine (P = 0.04). These findings indicate that non-motor symptoms like anhedonia, along with higher medication doses and specific treatments, play a significant role in influencing mortality risk in advanced PD. This study highlights the multifaceted nature of mortality risk in patients with PD, particularly emphasizing the role of non-motor symptoms and pharmacological treatment. Tailored therapeutic strategies, including closer monitoring of anhedonia and careful management of medication dosages, may be essential in reducing mortality and improving patient outcomes in advanced stages of PD.

Breast tuberculosis is a rare extrapulmonary manifestation of Mycobacterium tuberculosis, representing less than 0.1% of all breast pathologies in developed countries. However, in regions with high tuberculosis prevalence, such as India and Africa, its incidence is higher. The disease poses diagnostic challenges due to its ability to mimic breast carcinoma, leading to potential misdiagnosis and unnecessary surgical interventions. This study investigates the clinical and imaging characteristics of breast tuberculosis in a large cohort, with a specific focus on a rare case in a postmenopausal woman. A retrospective observational study was conducted on 1704 women who presented for mammography at the Alessandrescu-Rusescu National Institute for Mother and Child Health between 2019 and 2021. Clinical presentation, imaging results, and histopathological findings were analyzed to identify cases of breast tuberculosis. The study includes a comparative analysis with other granulomatous diseases and malignant breast conditions to highlight key diagnostic features. Among the 1704 patients, 714 (41.9%) presented with symptoms such as pain (35.4%), palpable lumps (13.2%), nipple discharge (4.3%), and breast appearance changes (2.1%). A rare case of primary breast tuberculosis was identified in a 69-year-old postmenopausal woman, presenting with a painless, palpable mass in the upper outer quadrant. Imaging demonstrated a hypoechoic mass with fine granular content and posterior acoustic enhancement, categorized as BIRADS 4A. The biopsy confirmed the diagnosis of breast tuberculosis. This study underscores the diagnostic complexity of breast tuberculosis, particularly in its ability to mimic malignancy. Through detailed imaging and clinical analysis, we emphasize the importance of biopsy in differentiating tuberculosis from breast cancer. Given the potential for misdiagnosis, clinicians should consider breast tuberculosis in differential diagnoses, especially in regions with high tuberculosis prevalence. Further research is needed to develop specific imaging criteria for earlier and more accurate diagnosis.
