A Review of Genetic Diversity Based on the Y Chromosome in the Romanian Population.

Y chromosome analysis is used in a number of practical applications, including investigations of criminal cases, establishment of paternity, searching for missing persons, studies on human migration, evolutionary research, and historical and genealogical investigations. Questions about the origin of individual ethnic groups are addressed not only through archaeological, linguistic, and ethnographic methods but also through molecular genetics methods. The study of genetic diversity in Romania is particularly interesting from several perspectives because Romania, located in Southeast Europe, is distinguished by the fact that the Carpathians and the Danube served as natural barriers against the migrations of peoples for centuries, thus influencing the genetic mixture of the population.

Emerging Perspectives on the Set of Conditions That Lead to the Emergence of Metabolic Syndrome.

Metabolic syndrome, as a medical condition, presents multifactorial complexity that is characterized by the resulting damage from genetic, environmental, and lifestyle factors (presence or absence of physical activity, food choices). Thus, metabolic syndrome qualifies unequivocally as a medical condition in which there are, simultaneously, several independent metabolic risk factors, namely, abdominal obesity, high triglyceride level, low HDL cholesterol level, arterial hypertension, and high glycemic level. Although age, sex, socio-economic status, and the precise definition of metabolic syndrome all influence the prevalence and risk of developing the condition, clinical and epidemiological studies clearly show that central obesity, as measured by an increased abdominal circumference, is the main risk factor.

Chronic Appendicitis: Possible Differential Diagnosis in Patients with Chronic Abdominal Pain.

In the emergency department, patients frequently present with abdominal pain, with a variety of different causes ranging from intra-abdominal to extra-abdominal and retroperitoneal pathologies which can affect all age groups. Chronic appendicitis is a rare medical condition characterized by less severe and continuous abdominal pain and a clinical picture lasting longer than 1-2 days and extending over months, even years, and it is not always possible to consider it as a preliminary diagnosis. We represent a case report of chronic appendicitis where the patient's clinical picture led the diagnostics and treatment in different directions and delayed the diagnosis.
