RESUMO

Fast track (FT) surgery is a multimodal concept aiming to reduce postoperative pain and stress-induced organ dysfunction. Key elements are perioperative fluid restriction, epidural analgesia, early oral nutrition and early mobilization. Therefore, multidisciplinary teamwork is required in order to obtain the optimal outcome of reduced postoperative complications and a hospital stay of only three or four days after open colectomy. Most of the patients undergoing colorectal surgery qualify for FT surgery. Meanwhile, FT principles are applied in a variety of open and laparoscopic procedures. The aim of this review is to highlight the principles of FT and to answer the question why FT surgery should nowadays be considered as standard care.

RESUMO

Peri-operative surgical stress (SS) is characterized by increased secretion of pituitary hormones and sympathetic activation and is correlated with changed blood levels of stress hormones and metabolites. Adverse effects of perioperative stress include mortality and morbidity and a negative nitrogen balance. Although peri-operative analgesia and stress response-free period are commonly considered as synonyms, pain seems not to be the only factor determining the hormonal-metabolic response to surgery. Other factors playing a role in the creation of SS in newborns include blood loss, site of surgery, superficial and visceral trauma, surgery duration, hypothermia, infection, prematurity and factors related to cardiac surgery. Potent semi-synthetic opioids attenuate the SS better than morphine. However, supplementation of general anesthesia (GA) with local anesthetics either by way of regional or local anesthesia seems to decrease SS more effectively than GA with IV opioids. Hemodynamic monitoring may not suffice for SS or analgesia quality estimation. The most accessible laboratory measure for the monitoring of the stress response for non-cardiac surgery and pre-bypass phase of cardiac surgery may be blood glucose. Blood glucose increases with stress and when analgesia is inadequate; it is easily measured and treated almost immediately once an excessive response is identified. This individualized approach and real-time feedback may be far better than using either excessive opioid doses (hoping to ablate stress response) or minimal opioid dosages.

RESUMO

Alzheimer's disease, AD, is the most common form of dementia. AD initially targets memory and progressively destroys the mind. The brain atrophies as the neocortex suffers neuronal, synaptic, and dendritic losses, and the hallmark amyloid plaques and neurofibrillary tangles proliferate. Pharmacological management, at best, is palliative and transiently effective, with marked adverse effects. Certain nutrients intrinsic to human biochemistry (orthomolecules) match or exceed pharmacological drug benefits in double-blind, randomized, controlled trials, with superior safety. Early intervention is feasible because its heritability is typically minimal and pathological deterioration is detectable years prior to diagnosis. The syndrome amnestic mild cognitive impairment exhibits AD pathology and to date has frustrated attempts at intervention. The condition age-associated memory impairment is a nonpathological extreme of normal brain aging, but with less severe cognitive impairment than amnestic mild cognitive impairment. Age-associated memory impairment is a feasible target for early intervention against AD, beginning with the modifiable AD risk factors - smoking, hypertension, homocysteine, type 2 diabetes, insulin resistance, and obesity. Stress reduction, avoidance of toxins, and mental and physical exercise are important aspects of prevention. The diet should emphasize omega-3 fatty acids docosahexaenoic acid and eicosapentaenoic acid; flavonoids and other antioxidant nutrients; and B vitamins, especially folate, B6 and B12. Dietary supplementation is best focused on those proven from randomized, controlled trials: the phospholipids phosphatidylserine and glycerophosphocholine, the energy nutrient acetyl-L-carnitine, vitamins C and E, and other antioxidants. A comprehensive integrative strategy initiated early in cognitive decline is the most pragmatic approach to controlling progression to Alzheimer's disease.

RESUMO

PURPOSE: To examine the effect of preoperative administering of a Japanese traditional herbal medicine, Hochu-ekki-to (TJ-41), on immunosuppression induced by surgical stress in patients with gastrointestinal malignancies. METHODS: To monitor the immune functions, the mitochondrial membrane potential (MMP) and natural killer (NK) cell activity prior to and following operation were measured in peripheral blood lymphocytes (PBL) in patients with (n = 20) or without (n = 27) the preoperative administering of TJ-41 for 7 days. The plasma catecholamine and interleukin (IL)-6 levels were also analyzed prior to and following the operation. RESULTS: The numbers of MMP-high CD56-positive cells (NK cells) and NK cell activities in the TJ-41-treated group were significantly higher than those in the control group (P = 0.026 and P = 0.037, respectively). An elevation of plasma noradrenaline and IL-6 following surgery was also inhibited by the preoperative administering of TJ-41 (P = 0.023 and P = 0.039, respectively). A positive correlation between MMP-high CD56-positive cell numbers and NK cell activity in PBL treated with carbonyl cyanide m-chlorophenyl hydrazone (CCCP) in vitro suggested that MMP measurement in CD56-positive cells can serve as a convenient alternative to evaluate the NK cell activity. CONCLUSION: Our findings suggest that the preoperative administering of TJ-41 prevents surgical stress-induced immunosuppression by maintaining the NK cell activity and inhibiting the elevation of stress mediators.

RESUMO

BACKGROUND: Infusion of hypertonic saline provides early haemodynamic benefits and may affect the immune system. It is unknown if infusion of hypertonic saline affects plasma cytokines and stress hormones after surgery. METHODS: Sixty-two women undergoing abdominal hysterectomy were randomized in a double-blind study to infusion of NaCl 7.5% (HS), NaCl 0.9% (NS4), both 4 ml kg(-1), or NaCl 0.9% 32 ml kg(-1) (NS32) over 20 min. Blood was collected at baseline, 1, 4, and 24 h after surgery (n=34) for the determination of interleukin (IL)-1beta, IL-6, IL-8, IL-10, IL-12, IL-1ra, and tumour necrosis factor-alpha. Serum cortisol and vasopressin were measured at these time points and 48 h after operation. Epinephrine and norepinephrine (n=26) were quantified at baseline, after infusion, 25 min after incision, 1, and 4 h after surgery. Finally, C-reactive protein was measured at baseline, 24, and 48 h after surgery. RESULTS: Surgery and anaesthesia induced well-reported changes in the concentrations of cytokines and hormones. The concentration of norepinephrine briefly increased after infusion of HS and NS32 but not NS4 (P<0.05). Epinephrine was increased 25 min after incision in Group NS32 compared with the other groups (P<0.05). No other differences were found between the groups. CONCLUSIONS: Infusion of a clinically relevant dose of hypertonic saline before hysterectomy appears to have limited effect on the postoperative concentration of selected plasma cytokines and the hormonal stress-response.

RESUMO

Dehorning adult cattle is a surgical procedure causing distress of varying intensities that can be reflected in behavioural changes and alterations in plasma cortisol levels. Stress responses during the dehorning process were evaluated in 18 Red Pied cows. The cows were divided into 3 groups of six and kept in tie-stall housing. Those in the first group were dehorned under general anaesthesia (GA) induced by intravenous administration of xylazine and ketamine. The second group was dehorned under sedation and local anaesthesia (SLA) induced by intramuscular administration of xylazine and local anaesthesia with lidocaine. The third group was dehorned under local anaesthesia (LA) with lidocaine. Dehorning was performed with a foetotomy wire. Blood samples were taken 0.5 h before dehorning to determine cortisol levels, and, by means of a central venous catheter inserted into the jugular vein, during surgery at 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 7 and 8 h post-surgery. Concurrently, occurrence of stress behaviours was assessed. Cortisol levels were measured by enzyme immunoassay (EIA). The lowest mean peak levels of plasma cortisol (82.53 +/- 6.04 nmol l(-1)), the most rapid return of plasma cortisol levels to baseline values (1.92 +/- 1.11 h), and the lowest occurrence of stress behaviours (2.38 +/- 5.83%) were noted in the SLA group. The highest mean peak levels plasma cortisol (113.86 +/- 25.65 nmol l(-1)), the slowest return of plasma cortisol levels to baseline values (3.83 +/- 2.18 h) and the most frequent occurrence of stress behaviours (65.48 +/- 28.72%) were observed in the LA group. There were significant differences between the SLA and LA groups in peak plasma cortisol levels (p = 0.011) and in occurrence of stress behaviours (p = 0.003). Sedation induced by intramuscular administration of xylazine in conjunction with local anaesthesia with lidocaine is considered the most suitable method of anaesthesia when dehorning adult cattle. Local anaesthesia with lidocaine alone was least suitable.

RESUMO

BACKGROUND: Music has been used for therapeutic purposes since the beginning of cultural history. However, despite numerous descriptions of beneficial effects, the precise mechanisms by which music may improve human well-being remain unclear. METHODS: We conducted a randomized study in ten critically ill patients to identify mechanisms of music-induced relaxation using a special selection of slow movements of Mozart's piano sonatas. These sonatas were analyzed for compositional elements of relaxation. We measured circulatory variables, brain electrical activity, serum levels of stress hormones and cytokines, requirements for sedative drugs, and level of sedation before and at the end of a 1-hr therapeutic session. RESULTS: Compared with controls, we found that music application significantly reduced the amount of sedative drugs needed to achieve a comparable degree of sedation. Simultaneously, among those receiving the music intervention, plasma concentrations of growth hormone increased, whereas those of interleukin-6 and epinephrine decreased. The reduction in systemic stress hormone levels was associated with a significantly lower blood pressure and heart rate. CONCLUSION: Based on the effects of slow movements of Mozart's piano sonatas, we propose a neurohumoral pathway by which music might exert its sedative action. This model includes an interaction of the hypothalamic-pituitary axis with the adrenal medulla via mediators of the unspecific immune system

RESUMO

BACKGROUND: The aim of the present randomized study was to determine the effect of adding sufentanil to bupivacaine, compared with bupivacaine alone in caudal block, on the surgical stress response in children. METHODS: The children were premedicated with midazolam 0.5 mg/kg. All children received induction with nitrous oxide and sevoflurane. Anesthesia was maintained with the same volatile agents in the both groups. The children were randomly allocated to two groups. Group I received bupivacaine alone (n = 17) and group II received bupivacaine + sufentanil (n = 16). Caudal block was performed with 0.25% bupivacaine 2 mg/kg (group I) or 0.25% bupivacaine 2 mg/kg with sufentanil 0.5 microg/kg (group II) after induction of anesthesia. Blood samples were obtained after induction of anesthesia (T(0)) to measure baseline concentrations of cortisol, prolactin, glucose and insulin. Additional samples were obtained 30 min after the start of surgery (T(1)), and 60 min after the end of surgery (T(2)). RESULTS: All of the basal values (T(0)) were within the normal ranges of the authors' laboratory for children of this age group and there were no differences between the groups (P > 0.05). In both groups, glucose concentration increased at T(1), compared with T(0) and T(2) (P < 0.05). The glucose concentration was unchanged at T(2) compared with T(0) in both group (P > 0.05). In both groups, prolactin concentration increased at T(1), compared with T(0) and decreased at T(2), compared with T(1) (P < 0.05). Cortisol decreased at T(1) and T(2), compared with T(0) in both groups. (P < 0.05). Insulin concentration remained unchanged at T(0) and T(2), but increased slightly at T(1) in both groups (P > 0.05). There were no significant differences in plasma prolactin, cortisol, glucose and insulin levels between the two groups at T(1) and T(2) (P > 0.05). CONCLUSION: There is no advantage in adding 0.5 microg/kg sufentanil to bupivacaine over bupivacaine alone in the caudal block, with regard to the surgical stress response in children.

RESUMO

We examined the effect of quercetin (3,3',4',5,7-pentahydroxyflavon) and KNK437 (N-formyl-3,4-methylenedioxy-benzylidene-gamma-butyrolactam), a benzylidene lactam compound, on heat-induced heat shock protein (hsp) gene expression in Xenopus laevis A6 kidney epithelial cells. In previous studies, both quercetin and KNK437 inhibited heat shock factor activity resulting in a repression of hsp mRNA and protein accumulation in human cultured cells. In this first study of the effect of these hsp gene expression inhibitors in a non-mammalian cell line, we report that both quercetin and KNK437 reduced the heat shock-induced accumulation of hsp30, hsp47 and hsp70 mRNA in X. laevis cultured cells. However, these inhibitors had no effect on the relative level of a non-heat shock protein mRNA, ef1alpha, in either control or heat shocked cells. Western blot and immunocytochemical analyses revealed that quercetin partially inhibited HSP30 protein accumulation. In contrast, HSP30 protein was not detectable in KNK437-treated cells. Finally, treatment of A6 cells with KNK437 inhibited the heat shock-induced acquisition of thermotolerance, as determined by preservation of actin filaments and cellular morphology using immunocytochemistry and laser scanning confocal microscopy.

RESUMO

Thousands of children receive methylphenidate (MPH; Ritalin) for attention deficit/hyperactivity disorder (ADHD), yet the long-term neurochemical consequences of MPH treatment are unknown. To mimic clinical Ritalin treatment in children, male rats were injected with MPH (5 mg/kg) or vehicle twice daily from postnatal day 7 (PND7)-PND35. At the end of administration (PND35) or in adulthood (PND135), brain sections from littermate pairs were immunocytochemically labeled for neurotransmitters and cytological markers in 16 regions implicated in MPH effects and/or ADHD etiology. At PND35, the medial prefrontal cortex (mPFC) of rats given MPH showed 55% greater immunoreactivity (-ir) for the catecholamine marker tyrosine hydroxylase (TH), 60% more Nissl-stained cells, and 40% less norepinephrine transporter (NET)-ir density. In hippocampal dentate gyrus, MPH-receiving rats showed a 51% decrease in NET-ir density and a 61% expanded distribution of the new-cell marker PSA-NCAM (polysialylated form of neural cell adhesion molecule). In medial striatum, TH-ir decreased by 21%, and in hypothalamus neuropeptide Y-ir increased by 10% in MPH-exposed rats. At PND135, MPH-exposed rats exhibited decreased anxiety in the elevated plus-maze and a trend for decreased TH-ir in the mPFC. Neither PND35 nor PND135 rats showed major structural differences with MPH exposure. These findings suggest that developmental exposure to high therapeutic doses of MPH has short-term effects on select neurotransmitters in brain regions involved in motivated behaviors, cognition, appetite, and stress. Although the observed neuroanatomical changes largely resolve with time, chronic modulation of young brains with MPH may exert effects on brain neurochemistry that modify some behaviors even in adulthood.

RESUMO

OBJECTIVE: To determine the effect of different doses of sufentanil on stress responses to tracheal intubation in patients undergoing heart valve replacement surgery. METHODS: Sixty patients undergoing heart valve replacement surgery were randomly divided into 4 groups (n=15). Before the tracheal intubation, patients received 10microg/kg fentanyl (Group A), 1microg/kg sufentanil (Group B ), 1.5micro/kg sufentanil (Group C), and 1.5microg/kg sufentanil (Group D), respectively, with midazolum and vecuronium intravenous injection. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and heart rate (HR) were recorded before the induction of anesthesia(T(0)), after the induction of anesthesia(T(1)), and at 1(T(2)), 3(T(3)), 5(T(4)), and 10 min after the tracheal intubation(T(5)). Rate-pressure product was derived from SBP and HR. Blood sugar was monitored at T(0), T(2) and T5. RESULTS: The SBP,DBP,MAP, HR and RPP at T(0) were not significantly different among the 4 groups (P>0.05). These parameters at T(1) were significantly lower than those at T(0) (P<0.01), but there was not significant difference among the 4 groups. The SBP, DBP, MAP in Group A increased significantly at T(2) and T(3) than those at T(1)(P<0.01 approximately 0.05), but were not significantly different than those at T(0)(P>0.05). The SBP,MAP in Group B,C,D at T(2) and T(3) were significantly lower than those in Group A (P<0.01 approximately 0.05 ). The SBP and MAP in Group D at T(4) were still lower than those in Group A (P<0.05). The HR at T(2) in Group A increased compared with that at T(1)(P<0.05),but was still lower than that at T(0). The HR at T(2) in Group B, C, and D was not significantly changed. The HR decreased significantly at T(2) in Group D compared with that in Group A(P<0.05), and the HR at T5 in Group A and D significantly decreased compared with that in Group B(P<0.05). The RPP at T(1) to T5 in Group B, C, and D significantly decreased compared with that at T(0)(P<0.01). The RPP at T(2) in Group A increased significantly compared with those in Group B, C, and D(P<0.01). The cases of using atropine during the induction and intubation in Group A,B,C, and D were 5(33.3%),0(0%),4(26.7%),5(33.3%),respectively, and the cases in Group B were significantly different compared with those in Group A and D(P<0.05). The change of blood sugar in Group A,B,C, and D was not significantly different(P>0.05). CONCLUSION: Three doses of sufentanil may effectively control the stress responses to the tracheal intubation in patients undergoing heart valve replacement surgery, and the hemodynamics during the intubation at 1microg/kg is much more stable.

RESUMO

PURPOSE/OBJECTIVES: To test the effects of an art-making class (AMC) on reducing anxiety and stress among family caregivers of patients with cancer. DESIGN: A pretest and post-test quasi-experimental design. SETTING: A residential care facility near tertiary treatment centers in the southeastern United States. SAMPLE: The convenience sample of 69 family caregivers was aged 18-81 years (X = 48 years) and predominantly Catholic. Most had at least a high school education. Two-thirds were daughters, wives, or mothers of patients with cancer. METHODS: Participants completed a demographic data survey and a Beck Anxiety Inventory (BAI). Researchers collected a saliva sample from each participant to measure salivary cortisol, which indicates stress levels. Following pretesting, a two-hour AMC was delivered. Post-tests included a repeat BAI and a second saliva sample. MAIN RESEARCH VARIABLES: Anxiety and stress. FINDINGS: Anxiety was significantly reduced after AMC. Stress was reduced. CONCLUSIONS: The AMC appeared to reduce anxiety and stress. The addition of a control group and replication with larger numbers are suggested. The physiologic cortisol measure corroborated BAI findings but was difficult to obtain from some cultural groups and was expensive to analyze. IMPLICATIONS FOR NURSING: Family caregivers may benefit from participation in art-making interventions. Nurses should continue to investigate the use of creative approaches to promote holistic care.

RESUMO

BACKGROUND: Most work sites engage in some form of health promotion programming designed to improve worker health and reduce health care costs. Although these programs have typically been delivered through combinations of seminars and print materials, workplace health promotion programs are increasingly being delivered through the Internet. OBJECTIVE: The purpose of this research was to evaluate the effectiveness of a Web-based multimedia health promotion program for the workplace, designed to improve dietary practices, reduce stress, and increase physical activity. METHODS: Using a randomized controlled trial design with pretest-posttest comparisons within each group, 419 employees of a human resources company were randomly assigned to the Web-based condition or to a condition that provided print materials on the same topics. All subjects were assessed at pretest and posttest through an online questionnaire containing multiple measures of health behavior and attitudes. The test period was 3 months. Questionnaire data were analyzed mainly by analysis of covariance and t tests. RESULTS: Retention rates were good for both groups-85% for the Web-based group and 87% for the print group. Subjects using the Web-based program performed significantly better than the print group on Attitudes Toward a Healthful Diet (F(1,415) = 7.104, P = .008) and Dietary Stage of Change (F(1,408) = 6.487, P = .01), but there were no significant group differences on the five other dietary measures. Both groups also showed improvement from pretest to posttest on most dietary measures, as indicated by significant t tests. Within the Web-based group, dosage analyses showed significant effects of the number of times the subject accessed the program on measures of Dietary Self-Efficacy (F(2,203) = 5.270, P = .003), Attitudes Toward a Healthful Diet (F(2,204) = 2.585, P = .045), and Dietary Stage of Change (F(2,200) = 4.627, P = .005). No significant differences were found between the two groups on measures of stress or physical activity, although t tests of pretest-posttest changes indicated that both groups improved on several of these measures. The Web-based group gave significantly higher ratings to the program materials than the print group on all health topics and in their overall evaluation (F(1,410) = 9.808, P = .002). CONCLUSIONS: The Web-based program was more effective than print materials in producing improvements in the areas of diet and nutrition but was not more effective in reducing stress or increasing physical activity. The higher ratings given to the Web-based program suggest that workers preferred it to the print materials. Both groups showed numerous pretest-posttest improvements in all health topics, although such improvements might be attributable in part to a Hawthorne effect.

RESUMO

Enhanced endoplasmic reticulum (ER) stress has been implicated in various pathological situations including inflammation. During a search for compounds that regulate ER stress, we identified vaticanol B, a tetramer of resveratrol, as an agent that protects against ER stress-induced cell death. Vaticanol B suppressed the induction of unfolded protein response-targeted genes such as glucose-regulated protein 78 (GRP78) and C/EBP-homologous protein (CHOP) after cells were treated with ER stressors. Analysis in the mouse macrophage cell line RAW 264.7 revealed that vaticanol B also possesses a strong anti-inflammatory activity. Production of a variety of inflammatory modulators such as tumor necrosis factor-alpha, nitric oxide, and prostaglandin E(2) was inhibited by vaticanol B to a much greater extent than by monomeric or dimeric resveratrol after exposure of cells to lipopolysaccharide. Further investigations to determine the common mechanisms underlying the regulation of ER stress and inflammation by vaticanol B disclosed an important role for vaticanol B in regulation of basic gene expression and in prevention of the protein leakage from the ER into the cytosol in both conditions. These results suggest that vaticanol B is a novel anti-inflammatory agent that improves the ER environment by reducing the protein load on the ER and by maintaining the membrane integrity of the ER.

RESUMO

OBJECTIVES: Surgery and anesthetic method have immunomodulating effects on hemodynamic response and stress. We compared the effects of 2 intraoperative analgesic regimens on patients undergoing abdominal hysterectomy. MATERIAL AND METHODS: We conducted a randomized double-blind trial in ASA 1 and 2 patients undergoing abdominal hysterectomy under balanced anesthesia. Twenty-nine patients were randomized to 2 groups. One group received analgesia by infusion of remifentanil plus morphine and nonsteroidal anti-inflammatory drugs as rescue medications; the other received conventional analgesia with bolus doses of fentanyl according to changes in hemodynamic variables. We measured levels of proinflammatory (interleukin [IL]-6) and antiinflammatory (IL-10) cytokines, cortisol, and C-reactive protein preoperatively, at incision, and at 1, 4 and 24 hours after surgery. RESULTS: There were no significant differences between the 2 groups in terms of the markers studied at baseline. In each group, however, there were significant changes from baseline at the various points in time. IL-6 and IL-10 levels were significantly elevated (P < .05) at 4 hours. The changes in cortisol levels were significantly different at 1 and 4 hours. Finally, there were significant increases in C-reactive protein at 24 hours. CONCLUSIONS: Unlike other clinical trials, our study detected no differences between the 2 techniques in response to surgical stress evaluated by analyzing concentrations of pro- and anti-inflammatory cytokines, cortisol, and C-reactive protein.

RESUMO

BACKGROUND: To determine if a lifestyle change program can modify behavior to reduce sleep and stress disorders. METHODS: Analyses are based on 2,624 individuals aged 30 to 80 years from the Rockford, Illinois metropolitan area who completed a lifestyle evaluation at baseline and again after four weeks, following participation in a 40-hour educational course given over a four-week period. Participants receive instruction on the importance of making better lifestyle choices related to making long-term improvements in nutrition and physical activity and they learn ways to improve sleep and reduce stress in their lives. RESULTS: Significant percent decreases were observed in the number experiencing selected sleep or stress disorders from baseline to four weeks later for "sleeps restlessly" (-59%), "suffers from insomnia" (-64%), "feels under pressure" (-37%), "easily emotionally upset" (-52%), and "feels fearful or depressed" (-61%). Experiencing a selected sleep or stress disorder after four weeks among those who had the disorder at baseline was significantly more likely in those not physically active and/or not having lowered their BMI after four weeks. Changes in alcohol consumption and smoking did not significantly contribute to changes in the disorders. Those who failed to lower their coffee/tea use after four weeks were significantly more likely to have a sleep disorder and be easily emotionally upset. CONCLUSIONS: Changes in lifestyle behaviors after attending an educational program significantly reduced sleep and stress disorders in as little as four weeks, primarily explained by decreasing BMI and/or increasing exercise.
