Association between Hand Hygiene Knowledge and Self-Efficacy in Nursing Students: A Multicenter Cross-Sectional Study within the Framework of the Erasmus Project.

Adherence to hand hygiene procedures is crucial for all populations, and the World Health Organization (WHO) has implemented specific guidelines for infection control. Frequent and correct hand hygiene can prevent infections, but non-compliance with hand hygiene is pervasive. Nursing students address this issue from the beginning of their training.

An Integrative Systematic Review of Promoting Patient Safety Within Prehospital Emergency Medical Services by Paramedics: A Role Theory Perspective.

Timely and effective prehospital care significantly impacts patient outcomes. Paramedics, as the frontline providers of emergency medical services, are entrusted with a range of critical responsibilities aimed at safeguarding the well-being of patients from the moment they initiate contact in the out-of-hospital environment to the time of handover at healthcare facilities. This study aimed to understand the multifaceted roles of paramedics in promoting patient safety within the context of prehospital emergency medical services.

[The problems of cataract surgery and intraocular correction: Russian school achievements and modern trends].

The development of the safest and, at the same time, efficient methods of cataract surgery, is not only a topical task of medical science and practice, but also, taking the demographic situation into account, a solution to a social problem. The article describes the main achievements of academician S. N.

[The function of the posterior corneal epithelium after exposure to ultraviolet laser radiation].

The method of contact mirror microscopy was used for assessment of the state of posterior epithelium of rabbit corneas before and after the action of laser ultraviolet radiation, lambda = 0.337 mmc. It was found that the usage of energy density of 5-20 mwt/cm2 and time exposures [correction of expositions] of 1, 5, 10, 15 min.

[Computerized tomography of the orbit and optic nerve canals in optic nerve atrophy of diverse etiology].

Computerized tomography has been used to examine 10 patients with cranial injuries aftereffects presenting as optic nerve atrophies (Group 1), 24 patients with nontraumatic optic nerve atrophies (Group 2), and 89 subjects without optic nerve abnormalities. Density asymmetry in the projection of the optic nerve canal cranial openings has been the computerized tomography sign that indicated the involvement of the optic nerve in Group 1 patients. Increased pneumatization of the main bone sinus has been detected 2 times more frequently in Group 2 patients.

[Correlations between clinico-functional and computerized tomography parameters in patients with optic atrophy of diverse etiology].

Comprehensive examinations of the optic nerve anatomy and function in atrophies of various origins have revealed a correlation between computerized tomography data and clinical and functional characteristics in 67 patients. A staged pattern of the development of anatomic shifts corresponding to CT data on the changes in the optic nerve diameter and density in accord with the length of the disease has been determined, as well as a relationship between these shifts and the patients' age and the degree of the calcification of the internal carotid arterial walls. CT signs of the optic nerve atrophy are related to functional disorders.

Retinal damage from intense visible light.

Studies of laboratory animal retinal exposure to green monochromatic laser radiation show an increasing stability of tissue with increasing pulse duration up to 10(-1) s. This mechanism of biological response of the eye to light damage is fundamental to living systems. It does not manifest itself in animals under deep anesthesia.

[Laser transscleral contact-compression coagulation of the fundus oculi tissues].

Experimental investigations were carried out in monkeys and rabbits for the purpose of quantitative and qualitative assessments of contact transscleral methods of action on intraocular, structures using ruby and AIH with Nd lasers adapted with a quartz monofiber. It was found that compression of a monofiber into the sclera produces its clarification, this providing effective transmission of radiation without any loss. Essential distinctions of the character of interaction between laser radiation and eye coats in transmission of radiation by a monofiber with its compression into the sclera allowed to substantiate and recommend for a clinical usage the contact-compression transscleral method of laser microsurgery.

[The mechanism of action of low-energy monochromatic coherent light on the lysosomal function of the retina].

A study of the state of retinal lysosomes under the action of low-energy monochromatic coherent light has shown that helium-neon laser radiation (lambda = 632.8 nm) to possesses a lysosomotropic action, changing structural functional parameters of lysosomal membranes, and the directness and intensity of the membranotropic effect on lysosomal structures of the retina depend on energy characteristics of the radiation used.

[Role of the gas composition of intraocular fluid in the regulation of intraocular circulation].

The recovery velocity of the acido-alkaline state of the intraocular fluid depended upon the ocular hemodynamics in the rabbit intraocular chamber. Oppressive action of hyperoxia and substitute hypocapnia on intraocular blood circulation was revealed. The RQ reduction described in some eye diseases and after intraocular operations can be connected with changes in gaseous composition of the intraocular fluid.

[Growth of Ectothiorhodospira mobilis in the dark].

The purple photosynthetic bacterium Ectothiorhodospira mobilis, like E. shaposhnikovii, can grow in the dark in the presence of oxygen on organic media, in particular, containing acetate or malate. The source of sulfur may be sulfate or thiosulfate.
