Randomized controlled trials - The what, when, how and why.

Randomized controlled trials (RCTs) are at the top of the pyramid of evidence as they offer the best answer on the efficacy of a new treatment. RCTs are true experiments in which participants are randomly allocated to receive a certain intervention (experimental group) or a different intervention (comparison group), or no treatment at all (control or placebo group). Randomization, along with other methodological features such as blinding and allocation concealment, safeguard against biases.

Technology beyond Biology; Isn't It Time to Update WHO's Definition of Health?

Technology is increasingly shaping human life, particularly in healthcare, where recent advancements have revolutionized patient care. Despite these advances, the World Health Organization's (WHO) definition of health remains rooted in traditional notions, raising questions about its adequacy in light of technological progress. This paper explores the conceptual and practical limitations of the current definition and argues for its revision to encompass the role of technology in health.

The Value of C-Reactive Protein and Peritoneal Cytokines as Early Predictors of Anastomotic Leak after Colorectal Surgery.

Objectives: The aim of this study was to evaluate the accuracy of serum C-reactive protein (CRP) and intraperitoneal CRP, interleukin-6, and tumor necrosis factor-alpha in early diagnostics of anastomotic leakage in the first 4 postoperative days after colorectal surgery.

Methods: Between January 2023 and June 2023, one hundred patients with colorectal carcinoma were operated on with primary anastomosis. Ten patients had anastomotic leak (10%).

Sex-Related Differences in the Associations between Adiponectin and Serum Lipoproteins in Healthy Subjects and Patients with Metabolic Syndrome.

The strong associations between the serum levels of adiponectin and the lipoprotein subclasses observed in healthy subjects are much weaker in patients with metabolic syndrome (MS). However, the impact of sex on these associations remained unexplored. Therefore, in the present study, we examined associations between adiponectin and the lipoprotein subclasses, analyzed by nuclear magnetic resonance spectroscopy, separately in healthy females and males, as well as in females and males with MS.

Impaired HDL antioxidant and anti-inflammatory functions are linked to increased mortality in acute heart failure patients.

Aims: Acute heart failure (AHF) is typified by inflammatory and oxidative stress responses, which are associated with unfavorable patient outcomes. Given the anti-inflammatory and antioxidant properties of high-density lipoprotein (HDL), this study sought to examine the relationship between impaired HDL function and mortality in AHF patients. The complex interplay between various HDL-related biomarkers and clinical outcomes remains poorly understood.

Undescended testis: A roundtable discussion based on clinical scenarios - Part 2.

Undescended testis (UDT, cryptorchidism) is the most frequent genital anomaly in boys. However, its treatment varies widely throughout the world. This second part of our roundtable discussion aims to continue to ask global experts to express their attitudes towards several case scenarios of UDT in order to explore the rationale for their clinical decisions.

Intentional vomiting as a rare cause of hypercalcemia and consequent acute renal failure: a case report.

Two most common causes of elevated serum calcium levels, which together account for nearly 90% of all cases, are primary hyperparathyroidism and malignancy. Thus, it is necessary to consider other disorders in the diagnostic evaluation of patients with hypercalcemia. We report the case of a 40-year-old female patient with an intellectual disability who was admitted to the Emergency Department with severe symptomatic hypercalcemia and acute renal failure, caused by recurrent intentional vomiting.

PD-L1 expression in testicular germ cell tumors undergoing spontaneous regression.

Spontaneous regression of testicular germ cell tumors is a well-known phenomenon; however, the precise mechanisms of spontaneous regression are still unknown. Our study aimed to investigate programmed death-ligand 1 (PD-L1) expression in spontaneously regressed testicular germ cell tumors, exploring the link between the immune response and spontaneous regression. From a sample of 356 testicular germ cell tumors, we singled out 5 completely regressed and 6 partially regressed tumors.

Literature review and case report: Rare case of successful prenatal detection of Vein of Galen Malformation (VGAM).

Vein of Galen aneurysmal malformation (VGAM) is a rare vascular anomaly originating during embryonic development, specifically between the 6th and 11th weeks of gestation. This malformation results from abnormal arteriovenous connections between primitive choroidal arteries and the median prosencephalic vein (MPV) of Markowski. Typically, the MPV regresses by the 11th week, but in VGAM, this regression is hindered, leading to persistent abnormal flow and the formation of arteriovenous shunts.

Step-by-step venous navigation in treatment of tentorial dural arteriovenous fistula supplied by artery of Bernasconi and Cassinari.

The artery of Bernasconi and Cassinari is a small infraclinoid branch of the internal carotid artery that originates from its cavernous segment and then runs along the tentorium. Because of its gracile appearance, it is often visible only when related to neoplasms and vascular lesions in the tentorial regions. Dural arteriovenous fistulas (dAVFs) are arteriovenous shunts contained within the dural leaflets, supplied largely by the regional meningeal arteries and classified based on the type of venous drainage.

Serum Levels of Adiponectin Are Strongly Associated with Lipoprotein Subclasses in Healthy Volunteers but Not in Patients with Metabolic Syndrome.

Metabolic syndrome (MS) is a widespread disease in developed countries, accompanied, among others, by decreased adiponectin serum levels and perturbed lipoprotein metabolism. The associations between the serum levels of adiponectin and lipoproteins have been extensively studied in the past under healthy conditions, yet it remains unexplored whether the observed associations also exist in patients with MS. Therefore, in the present study, we analyzed the serum levels of lipoprotein subclasses using nuclear magnetic resonance spectroscopy and examined their associations with the serum levels of adiponectin in patients with MS in comparison with healthy volunteers (HVs).

A Case Report of Brugada Syndrome Associated With Physical Trauma.

Brugada syndrome is an autosomal dominant channelopathy that usually affects healthy young males without apparent structural heart disease. It is associated with a spectrum of variable and dynamic clinical manifestations, high risk of life-threatening ventricular arrhythmias, and sudden cardiac death. Our patient demonstrated transient and dynamic EKG changes of both type 1 (coved) and type 2 (saddleback) ST elevation, suggestive of the Brugada pattern that was associated with physical chest trauma and stressful situations.

Stercoral perforation of the sigmoid colon in pregnancy: A case report.

A 39-year-old woman presented at 29 weeks and 4 days of gestation with abdominal pain and chronic constipation. The abdominopelvic magnetic resonance and ultrasound imaging were not conclusive. Computed tomography showed evidence of bowel perforation.

Advanced Oxidation Protein Products Are Strongly Associated with the Serum Levels and Lipid Contents of Lipoprotein Subclasses in Healthy Volunteers and Patients with Metabolic Syndrome.

The association between advanced oxidation protein products (AOPPs) and lipoprotein subclasses remains unexplored. Therefore, we performed comprehensive lipoprotein profiling of serum using NMR spectroscopy and examined the associations of lipoprotein subclasses with the serum levels of AOPPs in healthy volunteers (HVs) and patients with metabolic syndrome (MS). The serum levels of AOPPs were significantly positively correlated with the serum levels of very-low-density lipoprotein (VLDL), intermediate-density lipoprotein (IDL), and low-density lipoprotein (LDL); however, they were significantly negatively correlated with high-density lipoprotein (HDL).

Unusual presentation of late-stage ectopic tubal pregnancy (19 weeks' gestation): Case report and literature review.

Ectopic pregnancy is a medical condition in which a fertilized egg takes an unexpected detour away from the uterine cavity and the fallopian tube becomes a popular host, with the ampulla being the prime location. However, it can occur in other areas such as cervix, ovaries, or abdomen. The most common risk factors are pelvic inflammatory disease, previous pelvic or abdominal surgery, abnormal anatomy of genital organs, endometriosis, previous ectopic pregnancies, assisted reproductive technologies, endocrine disorders, and even the subtle influence of low-dose progestins from contraceptives.
