Effects of complementary spiritual therapy on stress, anxiety, burnout syndrome and hematological parameters of professionals in a public hospital: a randomized controlled trial.

OBJECTIVES: This randomized controlled trial evaluated the stress, anxiety, and burnout of professionals exposed to complementary spiritist therapy (CST), which consists in therapeutic resources as prayer, Spiritist passe, fluidic water and spiritual education or control. METHODS: Seventy-six professionals were randomized to CST or control: to maintain the routine for 5 weeks. The ISSL scale, anxiety and depression Beck's indices, Maslach instrument, subjective well-being and WHOQOL-BREF were used at baseline and five-week. Blood count and cytokine dosage were collected at baseline, one-week and five-week. Analysis using the intention to treat approach. RESULTS: The means of variation of stress (exhaustion phase) between baseline and five-week were -1.50 ± 3.31 in the CST and 0.72 ± 3.50 in the control (p=0.036), effect size for CST group was d=0.65, which is considered medium effect. CST showed decrease in emotional exhaustion and negative affects, and increase in lymphocytes, erythrocyte parameters and platelets between the baseline and five-week (p<0.05). Reduction in IL-1ß and increase in total lymphocyte count were observed with 2-3 sessions per week, but that does not maintain when the number of sessions is decreased. Participants receiving ≥7 sessions reduced emotional exhaustion, depersonalization and stress, and improved hematological parameters throughout the study (p<0.05). CONCLUSIONS: CST may be effective in reducing stress (exhaustion phase) compared to control. Higher frequency of interventions promotes better psychic state, evidenced by large effect size for emotional exhaustion in burnout, and improves hematological parameters of professionals.

Resorbable bacterial cellulose membranes with strontium release for guided bone regeneration.

Hybrid materials, based on bacterial cellulose (BC) and hydroxyapatite (HA), have been investigated for guided bone regeneration (GBR). However, for some GBR, degradability in the physiological environment is an essential requirement. The present study aimed to explore the use of oxidized bacterial cellulose (OxBC) membranes, associated with strontium apatite, for GBR applications. BC membranes were produced by fermentation and purified, before oxidizing and mineralizing by immersing in strontium chloride solution and sodium bibasic phosphate for 5 cycles. The hybrid materials (BC/HA/Sr, BC/SrAp, OxBC/HA/Sr and OxBC/SrAp) were characterized for biodegradability and bioactivity and for their physicochemical and morphological properties. In vitro cytotoxicity and hemolytic properties of the materials were also investigated. In vivo biocompatibility was analyzed by performing histopathological evaluation at 1, 3 and 9 weeks in mices. Results showed that the samples presented different strontium release profiles and that oxidation enhances degradation under physiological conditions. All the hybrid materials were bioactive. Cell viability assay indicated that the materials are non-cytotoxic and in vivo studies showed low inflammatory response and increased connective tissue repair, as well as degradation in most of the materials, especially the oxidized membranes. This study confirms the potential use of bacterial cellulose-derived hybrid membranes for GBR.

Preparation and characterization of carboxymethyl cashew gum grafted with immobilized antibody for potential biosensor application.

This report details the design of carboxymethylated cashew gum (CG) as a platform for antibody (Ab) immobilization, which can then be used as a biosensor for bacteria detection. The CG was isolated and characterized, followed by conversion to carboxymethyl cashew gum (CMCG). The CMCG film was a viable support for antibody immobilization; it was electrodeposited on gold surface using the cyclic voltammetry technique, applying a potential sweep from -1.0 V to 1.3 V with a scan rate of 50 mV s-1 and 10 scans. The COOH groups on the surface of the film were critical in promoting Ab bonding. The immobilization of the Ab was mediated by protein A (PrA) for recognition of the antigen. Voltammetry studies were used to monitor the antibody immobilization. Finally, the analytical response of the CMCG-PrA-Ab system was evaluated with the chronoamperometry technique and was found to detect Salmonella Typhimurium bacteria rapidly and efficiently.

Religiousness/Spirituality, Resilience and Burnout in Employees of a Public Hospital in Brazil.

The present study aimed to determine the relation between religiousness/spirituality (R/S), resilience and burnout in employees of a public hospital. A total of 57 participants were evaluated, and the R/S Brief Multidimensional Measure, Pesce and collaborators' resilience scale and Maslach Burnout Inventory were used. Most employees (91.2%) were females. It was observed that the burnout and resilience variables showed statistically significant differences in relation to R/S dimensions. The results identified an association between R/S, resilience and burnout, demonstrating that employees who are more religious and spiritualized have greater resilience and consequently are less often affected by burnout.

Treatment of acromegaly patients at the Federal University of Triângulo Mineiro (UFTM): Experience Report.

OBJECTIVE:: To evaluate the effectiveness of the treatment of acromegaly patients at the Federal University of Triangulo Mineiro. METHODS:: Cross-sectional and retrospective study of thirty cases treated over a period of two decades. RESULTS:: 17 men (56.7%) aged 14-67 years and 13 women aged 14-86 years were analyzed. Twenty-one patients underwent transphenoidal surgery, whichwas associated with somatostatin receptor ligands in 11 patients (39.3%), somatostatin receptor ligands + radiotherapyin 5 patients (17.8%), radiotherapy in 3 patients (10.7%), and radiotherapy + somatostatin receptorligands + cabergoline in 1 patient (3.6%). Additionally, 2 patients underwent radiotherapy and surgeryalone. Six patients received somatostatin receptor ligands before surgery, and 2 were not treated due to refusal and death. Nine patients have died, and 20 are being followed; 13 (65%) have growth hormonelevels o1 ng/mL, and 11 have normal insulin-like growth factor 1 levels. CONCLUSION:: The current treatment options enable patients seen in regional reference centers to achieve strict control parameters, which allows them to be treated close to their homes.

Stability of a functional beverage composed by tropical fruits and yacon (Smallanthus sonchiyo- lius) under refrigerated storage.

The development of beverages with functional properties must consider the preservation of the bioactive or functional properties during storage. For this reason, the aim of this study was to evaluate the stability of a functional beverage of tropical fruits and yacon, stored under refrigeration. The beverage, composed by 50% of yacon and 50% of a blended tropical fruits (camu-camu, acerola, cashew-apple, yellow mombin, acai and pineapple), was pasteurized (90 seconds/ 85°C) and stored under refrigeration (5°C). After processing and on 45 day intervals until the end of storage, were assayed the bioactive compounds (ascorbic acid and total extractable polyphenols), antioxidant activity, total soluble solids, titratable total acidity, pH, color (L*, a* and b*), total sugar content, sucrose, glucose and fructose, and nd the physical and chemical analyzes were limited by decreased total antioxidant activity and their bioactive components. The beverage showed relative physical and chemical quality during storage period, and in the 225 days of storage, the total extractable polyphenols and total antioxidant activity showed a significantly decline, and thus , these parameters were evaluated only until this period. However, the main limitation for the beverage storage was due to. sensory acceptability and microbiological safety, which although in accordance with Brazilian legislation, limited storage period for 90 days.

Pectinolytic enzymes secreted by yeasts from tropical fruits.

Three hundred yeasts isolated from tropical fruits were screened in relation to secretion of pectinases. Twenty-one isolates were able to produce polygalacturonase and among them seven isolates could secrete pectin lyase. None of the isolates was able to secrete pectin methylesterase. The pectinolytic yeasts identified belonged to six different genera. Kluyveromyces wickerhamii isolated from the fruit mangaba (Hancornia speciosa) secreted the highest amount of polygalacturonase, followed by K. marxianus and Stephanoascus smithiae. The yeast Debaryomyces hansenii produced the greatest decrease in viscosity while only 3% of the glycosidic linkages were hydrolysed, indicating that the enzyme secreted was an endo-polygalacturonase. The hydrolysis of pectin by polygalacturonase secreted by S. smithiae suggested an exo-splitting mechanism. The other yeast species studied showed low polygalacturonase activity.
