The impact of uterine cavity structural features on reproductive outcomes in T-shaped uterine malformation.

Objectives: Despite advancements in modern medicine, the effectiveness of in vitro fertilization (IVF) remains low. This study aimed to assess the impact of specific features of T-shaped uterine cavity malformation and its intermediate forms on reproductive function and the effectiveness of assisted reproductive technology (ART), particularly on IVF results and pregnancy outcomes.

Methods: A prospective cohort study included 388 somatically healthy patients undergoing 3D ultrasound (US) examination of the uterine cavity before embryonic transfer for IVF treatment.

Tracking the evolution of anti-SARS-CoV-2 antibodies and long-term humoral immunity within 2 years after COVID-19 infection.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that gave rise to COVID-19 infection produced a worldwide health crisis. The virus can cause a serious or even fatal disease. Comprehending the complex immunological responses triggered by SARS-CoV-2 infection is essential for identifying pivotal elements that shape the course of the disease and its enduring effects on immunity.

The Role of Complement System's C3 and C4 Fractions in the Pathogenesis of Uveitis.

Purpose: To study the role of the complement system's C3 and C4 fractions in the pathogenesis of different types of uveitis.

Methods: A prospective case-control study. 118 patients were enrolled.

Influence of ovarian cysts on ovarian reserve and fertility: A case-control study.

Objective: The aim of this study was to evaluate the impact of having an ovarian cyst and undergoing cystectomy on the expression of ovarian reserve markers among adolescent females who live in Armenia.

Methods: We conducted a prospective case-control study. Cases were arranged into two groups.

Kinetics of anti-nucleocapsid IgG response in COVID-19 immunocompetent convalescent patients.

The comprehension of a long-term humoral immune response against SARS-CoV-2 can shed light on the treatment and vaccination strategies of COVID-19 disease, improving the knowledge about this virus infection and/or re-infection. We assessed the IgG antibodies against SARS-CoV-2 nucleocapsid (N) protein (anti-SARS-CoV-2 (N) IgG) in 1441 COVID-19 convalescent patients within 15 months longitudinal study from middle-developed country. The main inclusion criteria was positive RT- PCR result on nasopharyngeal swab samples at least one month before antibody testing and absence of any induced or inherited immunodeficiency.

Reduction of Hospitalization and Mortality by Echocardiography-Guided Treatment in Advanced Heart Failure.

In advanced heart failure (AHF) clinical evaluation fails to detect subclinical HF deterioration in outpatient settings. The aim of the study was to determine whether the strategy of intensive outpatient echocardiographic monitoring, followed by treatment modification, reduces mortality and re-hospitalizations at 12 months. Methods: 214 patients with ejection fraction < 30% and >1 hospitalization during the last year underwent clinical evaluation and echocardiography at discharge and were divided into intensive (IMG; N = 143) or standard monitoring group (SMG; N = 71).

Is I-shaped uterus more common in patients with hyperandrogenism?

Objectives: Subtypes of T-shaped uterus are rare uterine cavity anomalies and there are no morphometric criteria for the diagnosis. Earlier we established a high frequency of I-shaped uterus in patients with adrenalhyperandrogenism, which is more common in Armenian populations. The aim of the study was to determine the frequency of I-shaped uterus as a subtype of T-shaped uterus in patients with ovarian and adrenal hyperandrogenism, accompanied by infertility and miscarriage, as well as the development of it's ultrasonic morphometric criteria.

Incidence patterns and review of Hodgkin lymphoma in the Republic of Armenia.

Hodgkin lymphoma (HL) accounts for roughly 10% of all lymphomas and 0.6% of all malignant tumours analysed worldwide yearly. Data regarding HL in developing world are exceptionally constrained.

The impact of T-shaped uterine cavity anomaly on IVF outcomes: More questions than answers.

Research Question: The aim of our study was the impact of T-shaped uterine anomaly on in vitro fertilization (per 1 IVF cycle per one embryo transfer) results and pregnancy outcomes.

Design: Prospective cohort study included 388 somatically healthy patients at the age of 20-40 years old who underwent 3-dimensional ultrasound of uterine cavity before embryo transfer. The uterine cavities were classified based on morphometric criteria according to the CUME study.

Peculiarities of situational and personal anxiety degree in the schoolchildren with ENT chronic diseases.

Background: A number of the QL researches in case of different pathologies are being increased during the last decade. The existing traditional research methods provide mostly arbitrary data on the disease and its treatment, which are not sufficient for the schoolchildren overall psychological and social adaptation and wellness evaluation.

Methods: The research object became schoolchildren of 3 randomly selected schools in Yerevan.
