Detection of Coronary Artery Disease With Coronary Computed Tomography Angiography and Stress Testing in Candidates for Liver Transplant.

Cardiac complications are the leading cause of morbidity and mortality in recipients of liver transplant (LT). Previous guidelines recommended stress testing to exclude coronary artery disease (CAD), although recent guidelines recommend coronary computed tomography angiography (CCTA). We aimed to assess the prevalence and predictors of CAD on CCTA and compare CCTA with stress testing in consecutive adult candidates for LT who underwent CAD noninvasive assessment between 2020 and 2023.

Heart Rate Lowering for Coronary CTA with Ivabradine in End-Stage Liver Disease.

In a study of 282 patients with end-stage liver disease undergoing coronary CT angiography, administration of a single dose of ivabradine (up to 15 mg) was found to be safe and effective at heart rate lowering.

Purulent pericarditis caused by methicillin-sensitive Staphylococcus aureus bacteriuria.

Background: Purulent pericarditis (PP)- a purulent infection involving the pericardial space-requires a high index of suspicion for diagnosis as it often lacks characteristic signs of pericarditis and carries a mortality rate as high as 40% even with treatment. Common risk factors include immunosuppression, diabetes mellitus, thoracic surgery, malignancy, and uremia. Most reported cases of PP occur in individuals with predisposing risk factors, such as immunosuppression, and result from more commonly observed preceding infections, such as pneumonia, osteomyelitis, and meningitis.

Cardiac rehabilitation for heart failure: progress and gaps in evidence and policy.

Purpose Of Review: This review synthesizes recent research on the efficacy, optimal design, and delivery methods of cardiac rehabilitation tailored to heart failure patients. Despite established benefits, cardiac rehabilitation referral and access disparities persist, necessitating elucidation of limitations and solutions.

Recent Findings: Exercise-based cardiac rehabilitation improves long-term mortality and hospitalization rates but not short-term mortality.

Performance of Computed Tomographic Angiography-Based Aortic Valve Area for Assessment of Aortic Stenosis.

Background A total of 40% of patients with severe aortic stenosis (AS) have low-gradient AS, raising uncertainty about AS severity. Aortic valve calcification, measured by computed tomography (CT), is guideline-endorsed to aid in such cases. The performance of different CT-derived aortic valve areas (AVAs) is less well studied.

Quantifiable In Vivo Imaging Biomarkers of Retinal Regeneration by Photoreceptor Cell Transplantation.

Purpose: Short-term improvements in retinal anatomy are known to occur in preclinical models of photoreceptor transplantation. However, correlative changes over the long term are poorly understood. We aimed to develop a quantifiable imaging biomarker grading scheme, using noninvasive multimodal confocal scanning laser ophthalmoscopy (cSLO) imaging, to enable serial evaluation of photoreceptor transplantation over the long term.

[An experimental study of the photodynamic properties of furfural and of the potentials for using a photoprotective cream].

Acute rabbit experiments have revealed furfural photodynamic characteristics. Photoprotective cream used to protect the skin from UV exposure could to a certain measure reduce the level of the photodynamic reaction developing in combined exposure to furfural and UV light. These data are recommended to be borne in mind when designing prophylactic measures.

[The experimental skin-resorptive action of furfural and a distillate of D-11 mineral oil].

Animal experiments have revealed manifest skin resorptive effect of furfural. Acute experiments have demonstrated manifest toxic action of furfural when applied to intact animal skin. Subacute action of mineral oil induced poorly manifest toxic effect manifesting as nonspecific visceral changes.

[Climacteric keratoderma (Haxthausen's syndrome)].

This condition was described by Haxthausen in 1934 for the first time; it is one of the diseases explained by hyperkeratosis of the palms and soles. This disease is difficult to diagnose, and patients often complain of such conditions; therefore the authors consider it useful to regularly publish descriptions of clinical cases. Besides involvement of the palms and soles, manifesting by hyperkeratotic layers, painful fissures and itching, the patients with climacteric keratoderma develop metabolic endocrine, neurovegetative, and psychoemotional disorders.

[Pyogenic dermatoses in the workers of the Apsheron oil production industry and the days of incapacity because of them].

A total of 2820 oilmen regularly exposed to industrial oil were examined. Folliculites were detected in 151, furuncles in 63, hydradenitis in 58, phlegmons in 35, panaritium in 30 subjects. The number of invalidity days due to pyogenic dermatoses was 2-3 times higher among the workers exposed to deep oils than among those handling surface oils; this difference is explained by chemical composition and physicochemical characteristics of the extracted oil.

[The level of immunoglobulins in the blood serum of guinea pigs with epicutaneous exposure to petroleum refinery products].

Blood serum IgG1, IgG2, IgA, and IgM were assayed by radial immunodiffusion after exposure of guinea pig skin to oil refinery products, mineral oil distillate D-11 (MOD) and furfurol (F), applied both separately and together. Application of MOD, F, and MOD + F subthreshold concentrations was found to be associated with a tendency to a reduction of IgG1 level; isolated applications of the agents in threshold concentrations involved statistically significant lowering of IgG1 (in exposure to MOD) and imbalanced levels of IgG1, IgG2, IgA, and IgM (in exposure to F). Combined application of both agents induced immunity shifts of other type as against isolated exposure.

[Changes in the morphological structure of the skin and internal organs of guinea pigs after multiple epicutaneous exposures to furfural, a distillate of D-11 mineral oil and their combinations].

Experimental multiple epicutaneous exposure of guinea pigs to furfural and D-11 mineral oil distillate and their combinations in various concentrations has resulted in structural changes of the skin and viscera. These changes were dose-dependent. Combined exposure to both agents resulted in more grave disorders than isolated exposures in the same doses.

[The irritating action of oil-refining products (furfural and mineral oil distillate D-11) on the skin of laboratory animals from isolated and joint exposures].

Experimental data demonstrate a manifest skin irritating action of D-11 mineral oil distillate and furfural used in oil processing. The minimal effective concentrations of these chemicals have been defined. The irritating effects are enhanced in exposure to their combination.

[The characteristics of photodermatoses in workers of the Apsheron petroleum industry].

Examinations of 518 refinery workers have revealed photodermatoses in 106. The disease ran a benign course: chronic or subacute one, eventuating in hyperpigmentation and vascular maculae in the workers exposed to oil and oil products. The patients suffering from occupational photodermatoses develop immunologic shifts, i.

[Measures for the combined therapy and prevention of dermatoses occurring in workers in contact with organophosphorus pesticides].

Allergenic and photosensitizing effects of organophosphorus pesticides (OPP) have been detected, as well as their destructive effect on the skin cell ultrastructure, on the body metabolism and enzymic systems, and the inhibitory effect on cholinesterase activity. Pesticide-induced changes in polyunsaturated fatty acids (PUFA) are significant in the mechanism of dermatoses development. The complex of treatment-and-prophylaxis measures includes regular dermatologic check-ups and limitation of the number of subjects handling OPP.

[The effect of occupational factors on immunologic indices in workers in the petroleum-refining industry].

Examinations of 518 refinery workers have helped define the dermatologic morbidity structure. Immunologic examinations have been carried out in 82 workers. 70 of these have developed skin abnormalities (toxicoderma, eczema, itching, hyperkeratosis, vascular spots, abnormal pigmentation, etc.
