Evaluation of the effect of Mozart music on pain and respiratory rate after thyroidectomy.

PURPOSE: Pain has always been a major concern in postoperative care. The aim of this study was to assess the impact of Mozart music on postoperative pain and physiological parameters in patients who underwent total thyroidectomy. METHODS: Patients scheduled for total thyroidectomy were randomly assigned to a music group or a control group. The music intervention was applied immediately after surgery, whereas the control group received only usual care. Measurements of pain perception and physiological parameters were performed before, during, and after the music intervention in the music group and at the same time points in the control group. Pain was evaluated with the visual analog scale. RESULTS: In a study population of 50 patients, a higher rate of decrease in pain was observed in the music group after the first 10 min of the music intervention compared to the control group (estimate = - 1.329; 95% CI [- 2.490, - 0.169]). Music also reduced respiratory rate by 1.31 rates/min more in the music group than in the control group at every assessment point (95% CI [- 2.171, - 0.451]). Changes in the remaining physiological parameters were not statistically significant between the music and the control group and within each group. CONCLUSION: This study suggests that the use of music during immediate postoperative care after thyroidectomy could accelerate pain relief and lead to a greater decline of respiratory rate compared to that achieved in usual care.

COVID-19 and Acute Cholecystitis Management: A Systematic Review of Current Literature.

Introduction: Since the beginning of the COVID-19 pandemic, many patients with clinically acute presentations have been approached differently. The fear of viral transmission along with the short period of study made patients delay their hospital visits and doctors reassess the approach of certain acute situations. This study aimed to assess the changes in the management of patients with acute cholecystitis before and during COVID-19. Methods: A systematic review of the literature using PubMed (MEDLINE), Scopus, and ScienceDirect databases was performed until 01 September 2021. Totally, two kinds of studies were included, those assessing the management of acute cholecystitis during COVID-19 and those comparing the periods before and during the pandemic. The outcomes recorded include management approaches, complications, and mean length of stay. Results: A number of 15 eligible articles were included in the study. During the pandemic, six studies revealed a shift toward conservative management of acute cholecystitis and five of them reported that conservative management was opted in 73% of the patients. On the contrary, data from all studies revealed that the surgical approach was preferred in only 29.2% of patients. Furthermore, when comparing the periods before vs. during COVID-19, the conservative approach was reported in 36.3 and 43.2% before vs. during COVID-19, respectively, whereas surgical intervention was performed in 62.5% of patients before COVID-19 and 55.3% during the pandemic. The length of stay was delayed when a non-surgical approach was selected in most studies. Complications, mainly classified by the Clavien-Dindo scale, were higher in the pandemic period. Conclusion: A tendency toward more conservative approaches was observed in most studies, reversing the previously used surgical approach in most cases of acute cholecystitis. In most of the examined cases during the COVID-19 pandemic, antibiotic treatment and percutaneous cholecystostomy were much more considered and even preferred.

Study of insulin resistance, TNF-α, total antioxidant capacity and lipid profile in patients with chronic heart failure under exercise.

Gluco-metabolic syndrome, oxidative stress and inflammation are common in chronic heart failure (CHF). Exercise training programmes are known to improve oxidative status, insulin sensitivity and endothelial function. In this study, the effects of walking on improving lipid and glucose metabolism in CHF patients, under statin treatment, were investigated. Fasting glucose, serum insulin, tumor necrosis factor-α (TNF-α), total antioxidant capacity (TAC), uric acid (UA), total cholesterol, triglycerides, high-density lipoproteins (HDL), direct low-density lipoproteins (LDL-dir), apolipoprotein-B, apolipoprotein-A1, and lipoprotein-a (Lp(a)) were monitored. Insulin resistance was depicted by fasting insulin resistance index (FIRI) (FIRI≥2.94±1.41). HDL significantly increased with walking and was positively correlated with the non-significant triglyceride decrease and significant Lp(a) decrease. Significant correlations were found in all CHF patients at baseline between FIRI and New York Heart Association (NYHA) functional class, ejection fraction, HDL, triglycerides and TNF-α. All non-diabetic CHF patients were characterized by insulin resistance. Serum insulin and fasting glucose significantly decreased with walking, while decrease in FIRI was positively associated with patients' adherence to the walking program. Elevated uric acid and TNF-α levels also significantly decreased. In conclusion, the present study demonstrated that moderate, unsupervised, everyday physical activity was able to ameliorate the lipid and glycemic profile of CHF patients, with simultaneous attenuation of inflammation and oxidative stress.

Oxidative damage to plasma proteins in patients with chronic alcohol dependence: the effect of smoking.

BACKGROUND: Accumulating evidence implicates oxidative stress in ethanol-induced toxicity. Ethanol has been reported to be involved in oxidative damage, mostly in vitro, or in post mortem tissues, while biochemical abnormalities in the blood or serum are scanty or lacking. The aim of the present study was to examine the oxidative status of plasma proteins as markers of oxidative stress in subjects with chronic alcohol dependence (CAD). Since smoking has also been associated with oxidative stress this factor was also considered. PATIENTS AND METHODS: A total of 71 patients with CAD and 61 healthy volunteers of comparable age were included in the study. The protein carbonyl assay was carried out in plasma, as a reliable measure of general oxidative protein damage, in these two groups. RESULTS: Increased plasma protein carbonyls (PCs) were found in patients with CAD as compared with the control group [mean values (nmollmg protein): 4.73+/-1.46 and 3.62+/-0.91 respectively, p<0.000001]. Within the control group, smokers had higher PCs than the non-smokers, however this difference was of marginal significance [mean values (nmol/mg protein): 3.93+/-1.32 and 3.47+/-0.63, respectively]. The CAD group had significantly increased PCs compared with both the smoker and the non-smoker subgroups of the controls (p<0.001 and p<0.0001, respectively). Duration of alcohol consumption, daily alcohol intake, smoke load, folic acid and vitamin B12 levels did not correlate significantly with PC levels. CONCLUSION: The above results support the evidence for systemic oxidative stress in CAD, which must be attributed mainly to alcohol consumption, while smoking may act synergistically.
