Effects of acupressure on dysmenorrhea and skin temperature changes in college students: a non-randomized controlled trial.

BACKGROUND: Complementary and alternative therapies may be adopted as nursing interventions to alleviate dysmenorrhea and improve productivity, creativity, work performance, and quality of life. OBJECTIVES: This study aimed to evaluate the efficacy of San Yin Jiao (SP6) acupressure as a non-pharmacologic nursing intervention for dysmenorrhea and identify its effects on temperature changes in two related acupoints as an explanatory mechanism of chi circulation. DESIGN: A non-equivalent control group pre and post-test design was employed to verify the effects of SP6 acupressure on skin temperature and dysmenorrhea. SETTING AND PARTICIPANTS: Young college women with primary dysmenorrhea were recruited from classrooms at two universities in Korea and 58 eligible participants were allotted to either a SP6 acupressure group or placebo group that received light touch on the SP6 acupoint. METHODS: The experimental group received acupressure treatment within the first 8h of menstruation, and severity of dysmenorrhea and skin temperature changes in the Zhongwan (CV2) and Qugu (CV12) acupoints were assessed prior to and 30 min, 1, 2, and 3h following treatment. RESULTS: There was a significant difference in severity of dysmenorrhea between the two groups immediately after (F=18.50, p=0.000) and for up to 2h (F=8.04, p=0.032) post treatment. Skin temperature was significantly elevated at 30 min after acupressure at the suprapubic CV2 acupoint in the experimental group compared to the control group. Temperature elevation was also noted at the epigastric CV12 acupoint post treatment but group differences were not significant, indicating that SP6 acupressure relieves dysmenorrhea primarily by temperature elevation in the CV2 pathway. CONCLUSIONS: Acupressure to the SP6 meridian can be an effective non-invasive nursing intervention for alleviation of primary dysmenorrhea, with effects lasting 2h post treatment.

Effects of self-efficacy, social support and knowledge on adherence to PEFR self-monitoring among adults with asthma: a prospective repeated measures study.

BACKGROUND: Long-term adherence to self-monitoring of peak expiratory flow rate (PEFR) is essential for early detection of declining lung function in individuals with asthma. Psychosocial and cognitive factors can influence adherence to PEFR self-monitoring behaviors. OBJECTIVES: The specific aims of this prospective, repeated measures study were to: (1) determine the effects of asthma self-efficacy, perceived satisfaction with social support and asthma knowledge on adherence to PEFR self-monitoring behavior; and (2) examine whether adherence to PEFR self-monitoring mediates the effects of psychosocial/cognitive factors on lung function and asthma symptoms in adults with asthma. DESIGN: Sixty-eight participants completed standardized questionnaires three times at baseline, 1 month, and 3 months and kept the records of PEFR self-monitoring behaviors twice a day. Data were analyzed using multiple linear regressions. Adherence rates to PEFR self-monitoring were 93.5% and 74.9% at 1 and 3 month, representing those who remained in the study (n=39). Other participants withdrew from the study. FINDINGS: Both at 1 and 3 month, psychosocial/cognitive factors as a whole did not account for a significant variance in adherence to PEFR self-monitoring. Univariate analyses, however, indicated that baseline asthma self-efficacy and asthma knowledge at 1 month were significant independent predictors for adherence to PEFR self-monitoring at 3 month. CONCLUSION: Adherence to PEFR self-monitoring did not mediate the effects of asthma self-efficacy, perceived satisfaction with social support, and asthma knowledge on lung function and asthma symptoms. Lung function was low, but participants reported low asthma symptoms, both of which remained stable over time. Because of a small sample size and high attrition, the findings of the study need to be interpreted with caution. Given the importance of long-term adherence to self-management in asthma and other chronic illnesses, factors influencing adherence need to be further investigated to set a basis for future interventions.

Implementing the research budget.

Reworking a reduced budget after the award and monitoring and managing the budget once funds are received are critical to the success of a research project. Few resources are available to help principal investigators and research teams deal with these components of grant implementation. This article will address strategies and concerns related to the revision of the postaward budget and the implementation of the budget. Among the strategies discussed for the revision of the postaward budget are cost sharing, renegotiation with administration, and reallocation of funds. Also addressed are topics related to monitoring and managing the budget, including understanding budget guidelines, account management and documentation, tracking expenditures, and challenges in grant budget management.

[Association of anger expression patterns and health status in health care workers].

PURPOSE: The purpose of this study was to examine anger-expression patterns and their association with state and trait anger and physical and psychological health status in health care workers. METHOD: Four hundred and forty eight nurses, physicians and technicians from a large medical center completed standardized questionnaires of anger, anger-expression patterns and mood. They also had blood pressure, cholesterol, blood glucose and body mass index measured during their annual physical examinations. Data was analyzed using descriptive statistics, independent t-test, chi-square and ANOVA. RESULTS: Subjects showed two major clusters of anger-expression patterns: anger-control and anger-in/out. Subjects with the anger-in/out pattern reported higher state and trait anger and more anxiety, depression and fatigue than subjects with the anger-control pattern. Physical health indicators, however, were not significantly different between the two clusters of anger-expression patterns. CONCLUSION: Anger-expression patterns are associated with psychological health status but not with physical health status. Anger-expression patterns, however, need to be examined over time to assess their long-term effects on the physical and psychological health status in future studies.

Relationships of asthma knowledge, self-management, and social support in African American adolescents with asthma.

Despite nationwide efforts to manage asthma, the adverse outcomes of asthma continue to increase, especially in African American adolescents. The purpose of this study was to examine the relationships among asthma knowledge, self-management, and social support in African American adolescents with asthma. A correlational descriptive study was conducted using a convenience sample of 53 identified asthmatic adolescents from the Southern metropolitan school system in Alabama. Asthma knowledge was measured by the Parcel Knowledge about Asthma Questionnaire, social support by the Norbeck Social Support Questionnaire, and asthma self-management behaviors by the Asthma Behavioral Assessment Questionnaire. Both asthma knowledge and social support had significant positive relationships (r=0.31, r=0.30, respectively) with asthma self-management behaviors and accounted for 14% of self-management behaviors variability. Further studies are needed to understand how to better manage asthma in adolescents.

Effects of SP6 acupressure on labor pain and length of delivery time in women during labor.

OBJECTIVE: The purpose of this study was to evaluate the effects of SP6 acupressure on labor pain and delivery time in women in labor. DESIGN: Randomized clinical trial. SETTING/LOCATION: Delivery room in a university hospital. PARTICIPANTS: Seventy-five (75) women in labor were randomly assigned to either the SP6 acupressure (n = 36) or SP6 touch control (n = 39) group. The participants were matched according to parity, cervical dilation, labor stage, rupture of amniotic membrane, and husband's presence during labor. There were no additional oxytocin augmentation or administration of analgesics during the study period. INTERVENTION: The 30-minute acupressure or touch on SP6 acupoint was performed. OUTCOME MEASURES: Labor pain was measured four times using a structured questionnaire, a subjective labor pain scale (visual-analogue scale [VAS]): before intervention, immediately after the intervention, and 30 and 60 minutes after the intervention. Length of delivery time was calculated in two stages: from 3 cm cervical dilation to full cervical dilatation, and full cervical dilatation to the delivery. RESULTS: There were significant differences between the groups in subjective labor pain scores at all time points following the intervention: immediately after the intervention (p = 0.012); 30 minutes after the intervention (p = 0.021); and 60 minutes after the intervention (p = 0.012). The total labor time (3 cm dilatation to delivery) was significantly shorter in the SP6 acupressure intervention group than in the control group (p = 0.006). CONCLUSIONS: These findings showed that SP6 acupressure was effective for decreasing labor pain and shortening the length of delivery time. SP6 acupressure can be an effective nursing management for women in labor.

Predictors of health behaviours in college students.

AIM: This paper reports a study examining the direct effects of perceived stress, perceived availability of and satisfaction with social support, and self-efficacy, and examines the intermediary roles of perceived threat (perceived susceptibility x perceived severity), benefits, and barriers on alcohol behaviour, smoking behaviour, physical activity and nutrition behaviour, general safety behaviour and sun-protective behaviour in college students. BACKGROUND: Health behaviours formed during young adulthood may have a sustaining impact on health across later life. Entering college can be an exciting, yet stressful event for many adolescents and young adults as they face trying to adapt to changes in academic workloads, support networks, and their new environment. Coupled with these changes and new-found responsibilities, they have greater freedom and control over their lifestyles than ever before. However, researchers have shown globally that many college students engage in various risky health behaviours. METHOD: A cross-sectional sample of 161 college students enrolled in an introductory psychology course completed self-report questionnaires regarding stress; social support; self-efficacy; and components of the Health Belief Model including perceived threat, perceived benefits, perceived barriers; and common health behaviours. Step-wise multiple regression analysis was conducted and significant predictors were retained as modifiers in the path analysis. FINDINGS: Self-efficacy significantly predicted alcohol and smoking behaviour, physical activity and nutrition protective behaviour, general safety protective behaviour and sun-protective behaviour. Under high-perceived threat, self-efficacy was mediated by perceived barriers for binge drinking and moderated by perceived barriers for physical activity and nutrition behaviours. In addition, under high-perceived threat, self-efficacy was moderated by perceived threat for alcohol use at 30 days and 6 months. Under low threat, self-efficacy was mediated by perceived barriers for smoking behaviour and general safety protective behaviours. CONCLUSIONS: Future health promotion programmes with college students must use interventions that maximize self-efficacy and ultimately reduce barriers to adopting a healthy lifestyle.

Sex differences in immune responses and immune reactivity to stress in adolescents.

The immune system is the body's major defense mechanism against disease. However, psychosocial factors, such as stress, can modulate various immune responses. Although they have been examined in adult humans and other animals, sex differences in immune responses and immune reactivity to stress have rarely been examined in adolescents, particularly comparing healthy and asthmatic adolescents. In 151 healthy and asthmatic high school adolescents (91 females and 60 males), natural killer cell (NK) cytotoxicity, polymorphonuclear leukocyte (PMN) superoxide release, lymphocyte proliferative responses, and CD subsets were measured twice: once during mid-semester and again during final examinations. There was little difference in these measures between healthy and asthmatic adolescents. Similarly, only sex difference was noted in NK cytotoxicity at a 25:1 effector-to-target cell ratio, with males showing significantly higher responses than females. For PMN superoxide release, females significantly increased their responses during final examinations, whereas males demonstrated no changes. For lymphocyte proliferative responses, both females and males increased their responses during final examinations, but the magnitude of increase was much greater in males. Furthermore, racial comparisons indicated that African American adolescents (n = 16), as compared with Caucasian adolescents (n = 128), had significantly higher responses in PMN superoxide release to N-Formyl-Met-Leu-Phe (FMLP) activation during mid-semester and lymphocyte proliferative responses at both time points. Nevertheless, the overall findings indicate limited differences in immune responses and immune reactivity to stress in adolescents between males and females, healthy and asthmatic adolescents, and Caucasians and African Americans. However, further investigations with larger samples are warranted.

Biopsychological markers of distress in informal caregivers.

BACKGROUND: Thirty caregiving wives participated in a study of caregiving distress and negative mood (depressive symptoms) by making diary entries on stressful caregiving situations and collecting saliva samples 4 times a day. At the end of the 7-day study period, caregivers' salivary cortisol production was compared with their diary entries and correlated with pencil and paper self-report scores of caregiver distress and depressive symptoms. FINDINGS: Despite the inability to control a number of factors thought to confound cortisol production (exercise, smoking, alcohol ingestion, and prescription medications), there was a statistically significant difference between No Caregiving and Caregiving cortisol, F(1,739) = 7.67, P = 0.006, with cortisol production higher when caregiving events occurred. However, efforts to code specific types of caregiving situations (e.g., 1 = indirect care; 4 = AD problem behavior care) did not further differentiate cortisol production. Although caregivers' self-reports for the same 7-day period indicated they were depressed, pencil-and-paper measures of distress and negative affect were not significantly correlated with cortisol production. CONCLUSIONS AND RECOMMENDATIONS: The finding that this caregiving group was significantly stressed by caregiving, as evidenced by increased cortisol production during caregiving episodes, verifies the importance of further exploration of specific caregiving situations as contributory factors in caregiver health and well-being. In that saliva is a relatively economical and comparatively noninvasive biological data source for community-based stress studies, methodological limitations of the study are identified and 5 recommendations are made for future biological marker studies of caregiver distress in community-based settings.

[Developing and testing the effects of a psychosocial intervention on stress response and coping in Korean breast cancer survivors: a pilot study].

PURPOSE: The purpose of this study was to develop a socioculturally-appropriate psychosocial intervention program for Korean patients with breast cancer and test its effects on stress, anxiety, depression, and coping strategies. METHODS: One group pretest and posttest design was used to test the effects of the intervention. A post-intervention interview was conducted to refine the nature of the intervention. A convenience sample of 10 breast cancer survivors was recruited from the outpatients clinics. Psychosocial intervention was developed to provide the health education, stress management, coping skill training and support weekly (90 min) for 6 weeks. RESULTS: There was a significant decrease in stress scores following the intervention (Z= -2.388, p=0.017). However, no significant changes were noted in the use of problem-focused and emotion-focused coping strategies, nor in the changes of anxiety and depression levels. Content analysis of interview data revealed six clusters; changes in perception, changes in problem solving approaches, changes in anger management, changes in life pattern, social support and reduction of perceived stress. CONCLUSIONS: Based on quantitative and qualitative data, we recommend the refinements of the intervention in the following areas for future studies: 1) duration, activities, and progression of psychosocial intervention; 2) research design and sample size; and 3) measurements.

Oxidative stress, DNA damage, and breast cancer.

Oxidative stress is a disturbance in the balance between the production of reactive oxygen species (ROS) and antioxidant defenses. It occurs when excessive production of ROS overwhelms the antioxidant defense system or when there is a significant decrease or lack of antioxidant defenses. Oxidative stress, in turn, is known to cause DNA damage and mutations of tumor suppressor genes that are critical initial events in carcinogenesis. Interestingly, early findings of the studies suggest that environmental factors, such as high psychological stress and poor nutritional profile (eg, low antioxidant and high fat intake), increase ROS production. Given that breast cancer is a complex disorder in which gene-environment interactions play a significant role in the development of cancer, oxidative stress may be an excellent model for exploring mechanisms mediating gene-environment interactions for nurse scientists and advanced practice nurses. Such investigations may help to suggest future strategies for nonpharmacological interventions for decreasing cancer risk.

Cardiopulmonary responses and adherence to exercise in women newly diagnosed with breast cancer undergoing adjuvant therapy.

Cardiopulmonary responses to an 8-week moderate-intensity aerobic exercise intervention and adherence to exercise during and after intervention were assessed in 41 women newly diagnosed with breast cancer undergoing adjuvant therapy. The intervention was primarily aimed at minimizing deconditioning. Women were randomly assigned to the intervention or control group, completed graded exercise tests before and after intervention, and encouraged to continue their exercise postintervention. Over time, only the intervention group showed significant decreases in resting heart rate, resting systolic blood pressure (SBP), P <.05 each, and maximum SBP, P <.02, and an increase in VO2 peak, P <.001, although resting SBP was higher in the intervention group at both timepoints, P <.05. The adherence rate to 8-week exercise intervention was 78.3% with average weekly attendance of 2.4 sessions and 42.7 minutes (27.8 minutes within target heart rate) exercise per session. Overall physical activity levels over 16 weeks postintervention did not differ between 2 groups. However, the within-group analysis indicated that only the intervention group showed a significant increase in voluntary activity, P < .02, and energy expenditure, P < .02, and a decrease in sedentary activity, P < .02. These findings indicate that moderate-intensity aerobic exercise is beneficial in reducing deconditioning of cardiopulmonary responses in newly diagnosed breast cancer women undergoing adjuvant therapy.

Fetal alcohol syndrome: a growing concern for health care professionals.

OBJECTIVE: To provide an integrated review of the literature on fetal alcohol syndrome (FAS) and fetal alcohol effects (FAE), focusing on the definition of FAS/FAE, their incidence and related problems, gestational research findings, FAS symptoms, the effects of prenatal alcohol consumption on offspring over time, and FAS/FAE preventive measures. DATA SOURCES: Computerized searches of MEDLINE and Web sites, as well as reference lists from published articles on FAS/FAE from 1973 to present. STUDY SELECTION: Literature was chosen from refereed journals and from current publications of the National Organization of Fetal Alcohol Syndrome. DATA EXTRACTION: Data were extracted using keywords relevant to FAS and FAS prevention. DATA SYNTHESIS: The consumption of alcohol during pregnancy can harm the fetus irreparably. Preventive measures can be helpful in decreasing or stopping the use of alcohol during pregnancy. CONCLUSIONS: Alcohol is a definite teratogen. The amount of alcohol, if any, that can be safely consumed during pregnancy, the exact physiological mechanisms that make alcohol unsafe for the fetus, and the most effective prevention measures have yet to be identified. FAS/FAE is still increasing in the United States.
