[Erectile dysfunction in railway station workers: principles of treatment (prospective randomized study)]. | LitMetric

AI Article Synopsis

Article Abstract

Introduction: Erectile dysfunction is often a consequence of stressful situations, lack of adequate sleep and rest, and sedentary lifestyles. The profession of locomotive engineer implies the presence of these negative factors, which in addition provoke high blood pressure and the development of hypertension.

Materials And Methods: A total of 85 patients of the urological and therapeutic departments of the "Clinical Hospital "Russian Railways Medicine" in the city of Barnaul", working as locomotive drivers or assistant drivers, were examined. 65 men with erectile dysfunction and hypertension of 1-2 stages (all received antihypertensive therapy) were randomly divided into 3 groups: in the group 1, an activator of endogenous nitric oxide synthase (NOS) was added to the treatment of hypertension; in group 2, a combination of an endogenous NOS activator and a phosphodiesterase-5 inhibitor (PDE-5) was used. Patients of group 3 did not receive additional treatment. The efficiency of treatment was assessed using markers of endothelial dysfunction, including plasminogen activator inhibitor type 1 (PAI-1), endothelin-1 (ET-1), homocysteine, high-selective C-reactive protein (hs-CRP). In addition, the International Index of Erectile Function and male copulatory function scores were filled out. Moreover, laser doppler flowmetry (LDF) with determination of blood flow in penile vessels was done. Follow-up examination was carried out after 2 and 4 months. Twenty of the persons were healthy and referred to the control group.

Results: There were no significant changes in markers and LDF values after 2 months in groups 1 and 3. In group 2, ET-1 and hs-CRP returned to the reference limits, which indicated a decrease in ischemia. After 4 months, there was an improvement in hemodynamics and marker values in group 2. The mean blood flow increased in group 1, while hs-CRP returned to the reference limits. In patients of group 2, a higher total IIEF and male copulatory function scores was documented. In group 3, there was no improvement.

Conclusion: The combination of hypotensive drugs, PDE-5 inhibitor and NOS activator showed the best effect, improving blood flow, reparative properties of endothelium with preventing of thrombus formation. Treatment with an NO synthase activator partially eliminates pathological processes in the endothelium.

Hyperbaric oxygen (HBO) therapy has emerged as a potential treatment, shown to enhance blood flow and angiogenesis. However, specific effects and mechanisms of HBO on limb ischaemia responding to a hypoxic environment remain largely unknown. We aimed to investigate the therapeutic potential of HBO in the treatment of limb ischaemia.

To investigate the effect of Keystone Design Perforator Island Flap (KDPIF) in the repair of maxillofacial soft tissue defect. From June 2021 to June 2023, 16 patients with soft tissue defects caused by resection of maxillofacial tumor repaired by KDPIF were selected. Variants of KDPIF were designed according to the area of the defect, and the incision was parallel to the wrinkle as far as possible in the same facial cosmetic subunit.

Background: Breast cancer is the leading cause of cancer-related deaths in women. Cytokines have been linked to various cancers, and both benign and malignant breast diseases are associated with inflammation. However, there is limited understanding of how the immune system's cytokine response varies among different subtypes of breast cancer.

Sickle cell trait (SCT) has been associated with alterations in various immune-related laboratory parameters including lower circulating lymphocyte counts. To further characterize the impact of SCT on the immune system, we performed flow cytometry of monocyte and lymphocyte immune cell subsets from peripheral blood mononuclear cells collected in a large, community-based cohort of SCT-positive (n = 68) and SCT-negative (n = 959) Black adults. SCT was significantly associated with lower proportions of CD8 and CD4 T cell subsets that include senescent-like markers of repeated immune system challenges.
