Improving outpatient care in chronic heart failure

Despite advances in pharma and high-technology medicine, the rate of burdensome hospital admissions and mortality in patients with chronic heart failure (CHF) remains high. Over half of all admission-entailing decompensations have been repeatedly shown to emerge from non-compliance with outpatient prescriptions. Poor adherence to medication and non-medication treatment can only be broken by improving the patient’s awareness of the disease and his closer monitoring by healthcare professionals. The power of clinical and laboratory illness monitoring in line with the recommended quality criteria of medical aid in heart failure (HF) is strongly limited today by time resources available in outpatient and midwifery clinics. Meanwhile, an international and certain domestic experience has been built up to run CHF outpatient centres with involvement of specially-trained nursing and senior medical staff. Analytic evidence on such centres suggests a reduction in mortality and hospitalisation rate among the visiting patients. To combat existing drawbacks of CHF outpatient care, the National Medical Research Center of Cardiology in alliance with the Specialist Society of Heart Failure have developed the nurses’ guidelines for CHF rooms and are launching a medical staff training programme to manage CHF rooms, registry and data analysis. Furthermore, a procedure has been developed for patient routing to regional CHF outpatient cabinets that is being actively deployed in the Tyumen Region

Optimization of intravascular volume determination in patients with acute decompensated heart failure

Acute decompensated heart failure (ADHF) is based on multilevel pathological pathways, which include hemodynamic overload and venous stasis. Determination of the volemic status is one of the most important tasks in managing such patients. Despite the availability of modern diagnostic markers (physical examination, chest x-ray, and brain natriuretic peptide (BNP) assessment), they do not accurately assess the degree of fluid overload, and therefore there remains a need to find a new, accurate and simple technology for assessing pulmonary congestion. The urgency of this problem has led to the development of a novel non-invasive remote dielectric sensing (ReDS) technology, which is a quantitative method for measuring the total volume of lung fluid by determining the tissue dielectric properties. The use of this technology makes it possible to quickly, non-invasively and quantitatively measure the fluid content in the lungs, makes it possible to optimize the treatment regimen and reduces the number of readmissions. This article presents the results of studies on the efficacy, safety and prospects for using a ReDS technology for the quantitative measurement of total lung fluid in patients with ADHF

Gallium-67 SPECT scintigraphy may be useful in diagnosis of temporal arteritis

Objective: To investigate the effectiveness and usefulness of (67)Ga SPECT scintigraphy in the diagnosis of TA. Methods: Nine patients (five male, four female) and six controls were included in the study. All of them received 8–10 mCi (67)Ga intravenously 48 hours before the scan.(67)Ga uptake ratios were calculated on transaxial and coronal slices. Results: All patients showed increased uptake in the temporal area of the skull compared with controls. Conclusion: The data suggest that (67)Ga skull SPECT may be useful in the diagnosis of TA, especially if the uptake ratio in the area of interest is calculated. Further studies are needed to confirm these data

Intraocular lens power calculation in the elderly population using the Kane formula in comparison with existing methods.

PURPOSE:To assess the accuracy of the Kane formula for intraocular lens (IOL) power calculation in comparison to established formulas in the elderly population. SETTING:Shiley Eye Institute, University of California San Diego, USA. DESIGN:Retrospective cohort. METHODS:Retrospective data from 90 patients ≥75 years old who underwent uneventful cataract surgery with SN60WF IOL implantation were evaluated. The first operated eyes of patients with final best-corrected visual acuity 20/40 or better and axial length 22-26 mm were included. Prediction errors were calculated for Barrett Universal II (BUII), Haigis, Hoffer Q, Holladay 1, Kane and SRK/T formulas. A subgroup analysis based on age (75-84 and ≥85 years old) was performed. RESULTS:Use of both BUII and Kane formulas resulted in the highest percentage of eyes with prediction errors within ±0.50 D (72% each) and significantly higher than Hoffer Q, Holladay 1 and SRK/T (p=0.001). Rates of predictability within ±0.25 D and ±1.00 D were 31%-38% and 87% -92%, respectively, with no significant differences between formulas. No statistically significant difference was seen between formulas in the median absolute error. These tendencies remained consistent in both age groups when analyzed separately. Subgroup analysis showed better predictability of all formulas in the younger age group. CONCLUSIONS:This is the first study evaluating the Kane formula exclusively in the elderly population. The Kane formula was found to be of equal accuracy to the BUII and superior to the Hoffer Q, Holladay 1 and SRK/T formulas. Very elderly patients may have reduced refractive precision using all formulas
