Two Groups (two + groups)
Selected AbstractsCross-Sectional and Longitudinal Studies of the Development of Group Differences in Acoustic Features of Coo Calls in Two Groups of Japanese MacaquesETHOLOGY, Issue 1 2006Toshiaki Tanaka Japanese macaques, Macaca fuscata, frequently utter coo calls to maintain vocal contact. Cross-sectional and longitudinal comparisons were conducted on the acoustic features of coo vocalizations of two groups of M. fuscata, Yakushima and Ohirayama groups, to explore the possibility of vocal plasticity. These two groups derive from the same local population but have been separated for more than 34 yr. The Yakushima group is non-provisioned, while the Ohirayama group is provisioned. Initially, coo calls in the two groups were compared cross-sectionally in females ranging from 0 to 18 yr. Mean values of the four variables studied (start, end, maximum, and minimum frequencies) were consistently lower in all age groups of the Ohirayama individuals compared with the Yakushima individuals. Secondly, longitudinal comparisons were conducted on individuals in the 1,4 yr after birth. Mean values of the five frequency variables studied (start, end, maximum, minimum and average frequencies) were again consistently lower in all age groups of Ohirayama compared with Yakushima individuals, although mean values of both groups gradually declined with an increase in age. Inter-group differences were significant at all ages in minimum frequency and at the first, second and third years in start frequency. Longitudinal comparisons of individuals aged 4,11 mo were also conducted. Regarding the four variables that differed between the two groups in the cross-sectional study, the mean values of minimum and start frequency did not differ significantly between the two groups at 4,5 mo, but were significantly lower in Ohirayama individuals aged 7,8 and 9,11 mo. Although provisioning may have had an effect on the weight difference between the groups, and consequently on vocalization frequency, these results suggest that the inter-group differences in coo call features form approximately 6,7 mo after birth as a result of vocal plasticity. [source] The effect of Chinese food therapy on community dwelling Chinese hypertensive patients with Yin-deficiencyJOURNAL OF CLINICAL NURSING, Issue 7-8 2010CuiZhen Shen Objectives., The objectives of this study are to evaluate the effectiveness of Chinese food therapy in correcting the Yin-deficiency and to examine its impact on the patients' quality of life and hypertension control. Background., Epidemiological studies have shown 14,50% of people with hypertension have Yin-deficiency. Whether restoring the Yin,Yang balance by means of Chinese food therapy can help to better manage patients with hypertension has yet to be examined. Design., Two groups randomised controlled trial. Methods., Eighty-five hypertensive patients recruited from two community health service centre were divided into two groups. The intervention group (n = 48) received specific dietary instructions and corresponding management of their antihypertensive medication if indicated and brief health education, whilst the control group (n = 37) received routine support involving only brief health education. Data were collected at baseline, after intervention at four, eight, 12 and 16 weeks follow-up. Comparisons were made to examine the effects of Chinese food therapy on Yin-deficiency symptoms, blood pressure and quality of life of hypertensive patients. Results., The intervention group had reduction in the numbers of antihypertensive medication taken as well as improvement in most of the Yin-deficiency symptoms after 12 weeks of Chinese food therapy and mean scores of several SF-36 dimensions were higher than that of in the control group after 12 and 16 weeks follow-up. Significant difference was found in systolic blood pressure in the intervention group when it was compared from baseline to after four and eight weeks respectively. Conclusion., Chinese Food Therapy can restore body constitution with Yin,Yang imbalance and may potentially improve hypertensive patients' quality of life. It is also beneficial in controlling blood pressure in hypertensive patients. Relevance to clinical practice., Chinese food therapy may become a complementary therapy in health care and it should be a component of nursing education and health education. [source] The role of community mental health nurses caring for people with schizophrenia in Taiwan: a substantive grounded theoryJOURNAL OF CLINICAL NURSING, Issue 5 2008Xuan-Yi Huang DNSc Aim and objectives., The aim was to develop a practice theory that can be used to guide the direction of community nursing practice to help clients with schizophrenia and those who care for them. Design., Substantive grounded theory was developed through use of grounded theory method of Strauss and Corbin. Methods., Two groups of participants in Taiwan were selected using theoretical sampling: one group consisted of community mental health nurses and the other group was clients with schizophrenia and those who cared for them. The number of participants in each group was determined by theoretical saturation. Semi-structured one-to-one in-depth interviews and unstructured non-participant observation were utilized for data collection. Data analysis involved three stages: open, axial and selective coding. During the process of coding and analysis, both inductive and deductive thinking were utilized and the constant comparative analysis process continued until data saturation occurred. To establish trustworthiness, the four criteria of credibility, transferability, dependability and confirmability were followed along with field trial, audit trial, member check and peer debriefing for reliability and validity. Results., A substantive grounded theory, the role of community mental health nurses caring for people with schizophrenia in Taiwan, was developed through utilization of grounded theory method of Strauss and Corbin. Conclusion., In this paper, results and discussion focus on causal conditions, context, intervening conditions, consequences and phenomenon. Relevance to clinical practice., The theory is the first to contribute knowledge about the field of mental health home visiting services in Taiwan to provide guidance for the delivery of quality care to assist people in the community with schizophrenia and their carers. [source] Structured reminiscence: an intervention to decrease depression and increase self-transcendence in older womenJOURNAL OF CLINICAL NURSING, Issue 2 2006Cynthia Kellam Stinson MSN Aims/objectives., The purpose of this study was to assess the effect of group reminiscing on depression and self-transcendence of older women residing in an assisted living facility in southeast Texas. There were two major objectives for this study. One objective was to determine if depression decreased in older women after structured reminiscence group sessions held twice weekly for a six-week period. A second objective was to determine if self-transcendence increased after structured reminiscence group sessions held twice weekly for a six-week period. Background., Reminiscence has been studied to determine its impact on a variety of conditions including but not limited to depression, self-esteem, fatigue, isolation, socialization, well-being, language acquisition and cognitive functioning. This review of research specifically focused on reminiscence, depression, self-transcendence and older people. Design/methods., Two groups were assessed at baseline, three and six weeks to answer the research questions. A sample of 24 women between the ages of 72 and 96 years were randomly assigned to either a reminiscence (experimental) group or the activity (control) group of the facility. Pearson's r was used to determine the magnitude of the relationship between subjects' responses on the Geriatric Depression Scale and the Self-Transcendence Scale. A mixed design analysis of variance (anova) was used to determine if there was a difference between the experimental and control groups on scores of the Geriatric Depression Scale and the Self-Transcendence Scale at baseline, three and six weeks. Conclusions., Data revealed a non-significant decrease in depression and increase in self-transcendence in the reminiscence group at the completion of six weeks, indicating a trend toward a positive result with reminiscence group sessions. The study also revealed an inverse relationship between depression and self-transcendence. These findings underscore the importance of screening older people for depression. Relevance to clinical practice., One of the primary modalities used for the treatment of depression in elderly women is medication. Antidepressant medications lead to harmful side effects without alleviating the underlying depression. For these reasons, there is a need to research alternative therapies for treatment of depression in the older female. Reminiscence offers a possible intervention for treatment of depression in older women. [source] Can the Neuropathic Pain Scale Discriminate Between Non-neuropathic and Neuropathic Pain?PAIN MEDICINE, Issue 2 2008David A. Fishbain MD, FAPA ABSTRACT Objectives., 1) To determine if the neuropathic pain scale (NPS) can be used to classify chronic pain patients (CPPs) as having primarily neuropathic vs non-neuropathic pain, and furthermore; 2) to determine what, if any, cut-off score can be used to reliably make this determination. Design., A total of 305 CPPs consecutive admissions to The Rosomoff Pain Center were administered the NPS and were assigned a diagnosis according to the physical examination and all available test results. CPPs with a diagnosis of chronic radiculopathy and spondylolysis/degenerative arthritis were segregated into two groups for the purposes of having a group representative of neuropathic pain (chronic radiculopathy) and non-neuropathic pain (spondylolysis/degenerative arthritis). Applying neuropathic pain criteria to each "of these two groups": a neuropathic pain "subtype" was identified within the chronic radiculopathy group; and, a non-neuropathic pain "subtype" was identified within the spondylolysis/degenerative arthritis group. This step was performed in order to assure that the CPPs selected for further analysis were truly representative of neuropathic and non-neuropathic pain. Discriminant function analysis was then employed to determine if NPS scoring could differentiate between these two "subtypes." Results from the discriminant function analysis model were utilized to derive an NPS cut-off score above which CPPs would be classified as having neuropathic pain. For the diagnoses of myofascial pain syndromes, spinal stenosis, epidural fibrosis, fibromyalgia, complex regional pain syndromes 1 and 2, and failed back surgery syndrome, a predicted NPS score was calculated and compared with the cut-off score. Setting., Multidisciplinary pain facility. Patients., Chronic pain patients. Results., The NPS appeared to be able to separate CPPs into neuropathic pain vs non-neuropathic pain subtypes. The derived cut-off score from the model was 5.53. Myofascial pain syndrome and spinal stenosis had predictive scores lower than this cut-off score at 3.81 and 4.26, respectively. Epidural fibrosis, fibromyalgia, complex regional pain syndromes 1 and 2, and failed back surgery syndrome had predictive scores higher than the cut-off score at 6.15, 6.35, 6.87, 9.34, and 7.19, respectively. Conclusions., The NPS appears to be able to discriminate between neuropathic and non-neuropathic pain. A debate is currently raging as to whether diagnoses, such as fibromyalgia and complex regional pain syndrome 1, can be classified as neuropathic. Our NPS cut-off score results suggest that these diagnoses may have a neuropathic pain component. The reliability and validity of our NPS method will need to be tested further in other neuropathic pain models, such as diabetic peripheral neuropathic pain. [source] | ||||||||||
