Do chronological age and selected socio-demographic factors affect quality of life in females with breast cancer?

The main aim of this study is to determine whether chronological age and selected socio-demographic factors affect quality of life in females with breast cancer. The sample group consisted of 145 females between 32.0 and 84.4 years of age, after radical surgery treatment, chemotherapy, radiotherapy and undergoing hormonotherapy. The results indicate no significant differences between individuals varied by chronological age, and by place of residence. The time elapsed since the diagnosis was a significant differentiating factor in terms of the self-reported extent of positive emotions, cognitive problems and sexual functioning. Higher educated females were more inclined to social avoidance and more severely affected by fatigue - those with partners more so than single ones. The distress related to the disease and its treatment degrades the patients' quality of life so severely that other factors, such as socio-demographic, chronological age or period since diagnosis, do not play as an important role in a subjective evaluation of quality of life. One needs to be cognizant of the variety of coexisting factors, including psychological and characterological, that contribute to the quality of life evaluation.

Abstract

The aim of the study was to determine the impact of steroidal medications on the structure and mechanical properties of supporting tissues of sheep under experimentally-induced osteoporosis. A total of 21 sheep were used, divided into three groups: a negative control (KN) (n = 3), a positive control (KP) (n = 3) with ovariectomy, and a steroidal group (KS) (n = 15) with ovariectomy and glucocorticosteroids. All animals were kept on a low protein and mineral diet and had limited physical activity and access to sunlight. Quantitative computed tomography was the examination method. The declines in the examined parameter values in the KS group were more than three times higher than in the KN group. The study suggests that a glucocorticosteroidal therapy accelerates and intensifies processes taking place in the course of osteoporosis. The combination of glucocorticosteroids with ovariectomy, a restrictive diet, limited physical activity, and no access to sunlight leads to a decrease in radiological bone density.

Abstract

The influence of docosahexaenoic (DHA) acid obtained from a new generation of eggs on ventricular electrical function of 24 pigs with experimentally induced tachycardiomyopathy was described. Two groups were formed, 12 pigs had experimentally evoked tachycardiomyopathy and were getting standard feed (control group TIC). Twelve pigs with tachycardiomyopathy received feed with an addition of a dietary supplement containing phospholipids isolated from new generation of eggs at a dose of 1,000 mg of DHA/animal/24 h (experimental group TIC). Electrophysiological study was carried out from an external programmer immediately after implantation of the pacemaker. All the tests were carried out in general anaesthesia. After 8 weeks of fast ventricular pacing at 170 bpm in pigs receiving phospholipids obtained from eggs, a statistically significant shortening of ventricular refraction time was observed during sinus rhythm and also during the ventricular pacing of 130 bpm, and 150 bpm in the group of pigs fed standard feed. The ventricular refraction time in the sinus rhythm was significantly longer after 12 weeks of fast pacing and in the pacing at 130 bpm and 150 bpm it was significantly longer after 8 weeks of fast pacing. Phospholipids containing high percentage of n-3 polyunsaturated fatty acids (PUFA) obtained from new generation of eggs may contribute to the shortening ventricular refraction period after its oral administration. The n-3 PUFA obtained from a new generation of hen eggs may be an alternative to fish oil source of DHA and other polyunsaturated fatty acids.

Abstract

Introduction: Pacemaker implantation is the only effective symptomatic treatment for life-threatening bradyarrhythmias. Major complications observed after implantation of cardiac pacemakers include lead dislocation, loss of pulse generator function, and inadequate stimulation. The aim of this retrospective single-centre study was to analyse the indications for pacemaker implantation and the incidence and types of complications associated with this procedure in dogs treated for symptomatic bradyarrhythmia.

Material and Methods: The retrospective analysis included 31 dogs with symptomatic bradyarrhythmia, implanted with permanent cardiac pacemakers in 1992–2017. The list of analysed variables included patient age, breed, sex, indication for pacemaker implantation, comorbidities, and the incidence of procedure-related complications along with the type thereof.

Results: The most common indication for pacemaker implantation was 3rd degree AVB, followed by SSS, advanced 2nd degree AVB, and PAS. Pacemaker implantation was associated with a 35% overall complication rate and 6.45% periprocedural mortality. There were no significant differences in terms of procedure-related complications with regard to age, sex, breed, indications for pacemaker implantation, or comorbidities.

Conclusions: Cardiac pacing is the only effective treatment of symptomatic bradycardia, but as an invasive procedure, may pose a risk of various complications, including death.

Abstract

The aim of this study was to investigate the usefulness of new software Pixel Flux (PXFX) for clinical evaluation of tissue perfusion in the field of reproduction in dogs. The experiment was performed on six adult Beagle dogs. Different organs and tissues of the animals were examined with the MyLab25 Gold ultrasound system. Blood flow in the ovary, testicle, prostate, the ramification of the penile artery, and the network of blood vessels of the pampiniform plexus were examined with the use of colour coded Doppler technique, and obtained data was evaluated with the PXFX software. The more objective digital evaluation of data obtained with colour Doppler sonography through the application of dynamic tissue perfusion measurements provides new opportunities for diagnosis, as well as continuous monitoring of the function of the examined tissues and organs. The use of PXFX software is strongly indicated as a tool in small animal practice as an additional method for evaluation of tissue perfusion, especially in the cases when other methods like pulsed wave Doppler techniques are difficult to be performed

Abstract

The aim of the study was to assess the atrioventricular conduction in the model of porcine pacing induced tachycardiomyopathy. Fifty-one swine were examined: 27 were paced and 24 served as a control group. Every 4 weeks, the animals were anaesthetised for 1 h and an ECG Holter was performed. Thirty minutes after the onset of anaesthesia, P-R and R-R intervals were measured. Each result was assigned to the subgroup according to the animal’s weight and the presence or absence of previous pacing. P-R interval was longer in animals after at least 4 weeks of rapid ventricular stimulation than in adjusted group of the animals according to the body mass. Multivariate analysis has showed that longer P-R interval was related to male gender, higher body mass, slower heart rate, and history of previous pacing. Chronic ventricular pacing led to the slowing of atrioventricular conduction. The presence of differences in the duration of R-R intervals between groups was only found in swine weighing 120-139 kg. The R-R interval was shorter in paced animals, whereas PR interval was longer in that group, indicating that PR prolongation is related to electrical or structural remodelling of the cardiac conductive tissue but not increased sympathetic nervous system activity, which is expected to produce corresponding changes in PR and R-R intervals.
