Differential effects of metoprolol and atenolol to neuropeptide Y blockade in coronary artery disease

Objective. To explore possible differential effects between metoprolol and atenolol in patients with coronary artery disease. Design. The study was randomized, double blind, two-way crossover with the Y1 antagonist AR-H040922 given as IV infusion for 2 h or placebo. Most patients were treated with metoprolol or atenolol. In a post hoc analysis we compared the hemodynamic response to exercise of the Y1 antagonist in patients on metoprolol (n = 16) and atenolol (n = 5), and assessed respiratory sinus arrhythmia (RSA), an indirect measurement of cardiac vagal activation, in the placebo phase in patients on metoprolol (n = 26) and on atenolol (n = 24). Results. 1) The Y1 antagonist reduced the systolic blood pressure rise during and after exercise during atenolol, but not during metoprolol, while heart rate and maximal load were similar with the two beta-blockers and not affected by the Y1 antagonist. 2) At equal heart- and respiration-rate 7–8 min after exercise the RSA was significantly lower in atenolol than in metoprolol patients, while no difference was seen at rest before exercise. Conclusion. These findings from this hypothesis generating study indicate that peripheral effects of NPY contribute less to cardiovascular stress reactions in patients on metoprolol than in those on atenolol.

Stress and quality of life in psoriasis: an update

Psoriasis is a chronic, relapsing, cutaneous condition with 1-2% prevalence in the general population. There are many factors involved in the induction and/or exacerbation of psoriasis of which stress is a well-known trigger factor in the appearance or exacerbation of psoriasis. Stress reaction in patients with psoriasis is probably mediated by the hypothalamic-pituitary-adrenal relationship with immunologic effects. Stress response involves increased levels of neuroendocrine hormones and autonomic neurotransmitters. Psychological stress or an abnormal response to stressors has been found to modify the evolution of skin disorders such as psoriasis. It can also have substantial psychological, and psychosocial impact on a patient's quality of life. Treatment regimens include stress-reduction strategies, such as biofeedback, meditation, yoga, and self-help approaches. This review focuses the relationship between psoriasis and stress, especially relating to psychosocial, psychological, and emotional stress aspects.

Psychological and systemic stress reactions of patients during hyperthermia treatments

Purpose: This study evaluated psychological stress reactions during hyperthermia (HT) treatments and compared them to systemic stress reactions.Materials and methods: 27 patients with malignant disease were treated with superficial or regional hyperthermia. Cortisol and the catecholamines adrenaline and noradrenaline in venous blood were used as markers of psychological stress. The anxiety proneness of the patients was evaluated with a trait-anxiety inventory. Blood pressure and heart rate were markers of systemic stress. Patients were first grouped by superficial or regional treatment and then into two subgroups: anxious and non-anxious patients.Results: The time course of the cortisol concentration of the superficial group showed a slight but significant decrease and that of the regional group an increase. The cortisol concentration of the regional group was sometimes slightly but significantly higher than in the superficial group, and in the group of anxious patients higher than in the group of non-anxious patients. The changes in time courses and differences in groups were not as pronounced for the catecholamine concentrations. Heart rate and blood pressure showed a significant increase only in the regional group, and there was no significant difference between the regional and the superficial groups. None of the variables showed a significant difference between the initial and the subsequent treatments; all lay well within the normal physiological range.Conclusions: These standard hyperthermia treatments are not excessively stressful, either systemically or psychologically. The different behaviours of the variables confirm that it makes sense to consider systemic stress as well as psychological reactions.

Evaluation of leukocyte esterase and nitrite strip tests to detect spontaneous bacterial peritonitis in cirrhotic patients

Laparoscopic surgery is the main treatment method for patients with gastrointestinal malignant tumors. Although laparoscopic surgery is minimally invasive, its tool stimulation and pneumoperitoneum pressure often cause strong stress reactions in patients. On the other hand, gastrointestinal surgery can cause stronger pain in patients, compared to other surgeries. Transversus abdominis plane block (TAPB) can effectively inhibit the transmission of nerve impulses caused by surgical stimulation, alleviate patient pain, and thus alleviate stress reactions. Remazolam is an acting, safe, and effective sedative, which has little effect on hemodynamics and is suitable for most patients. TAPB combined with remazolam can reduce the dosage of total anesthetic drugs, reduce adverse reactions, reduce stress reactions, and facilitate the rapid postoperative recovery of patients.
