Abstract BACKGROUND Sleep disorder, brings in many physical, behavioral, and mental problems. Applying continuous care model leads to proper recognition of the patient’s problems and involves the patient in solving health problems. This study aimed to determine the effect of continuous care model on the quality of sleep in menopausal women. METHODS AND MATERIALS A random clinical trial study was carried out with participation of 110 menopausal women visiting Kermanshah-based clinics (the west of Iran) in 2017. The participants were randomly assigned to intervention (n=55) and control (n=55) groups. The control group received the routine cares and in addition to the routine cares the intervention group attended four weekly group consultation sessions (60-90min). The quality of sleep in the two groups was assessed using Pittsburg Sleep Quality Index before, immediately after, and one month after the intervention. Data analyses were done using independent t-test, ANOVA with frequent measures, Friedman’s test, Wilcoxon’s post hoc test, and X2 test in SPSS (24). RESULTS The mean scores of quality of sleep before and after the intervention were significantly different in the intervention group (p=0.001). There was no significant difference between the two groups in terms of quality of sleep before (p=0.140) and immediately after the intervention (p=0.168). However, one month after, the difference between the two groups was significant (P<0.001). CONCLUSION Implementation of the continuous care model led to an improvement of quality of sleep in the menopausal women.

Background: Asthma may be considered as a non-communicable condition associated with higher bronchial responsiveness that may impair quality of life (QoL). Purpose: The research aim was to compare scores of depression, as well as general and foot health-related QoL, in patients who suffered from asthma with respect to healthy subjects. Methods: A total sample of 152 subjects, median age of 37.00 ± 16.00 years, were recruited from a respiratory and allergy department of a hospital and divided into patients with asthma (n = 76) and healthy subjects (n = 76). The scores of the Spanish foot health status questionnaire (SFHSQ) domains as well as the Spanish Beck’s Depression Inventory (BDI) scores and categories were collected. Results: The only statistically significant difference (p < 0.05) was shown for the difference of the FHSQ footwear domain establishing that patients who suffered from asthma presented a worse QoL related to foot health for footwear (lower FHSQ scores) compared to healthy matched-paired participants (higher FHSQ scores). Regarding the rest of the outcome measurements, there were no statistically significant differences (p > 0.05) for the other FHSQ domains scores as well as the BDI scores and categories. Conclusions: Patients with allergic asthma presented impairment of the QoL related to foot health for footwear, which seemed to be linked to the presence of asthma.

Comparisons have been made of the milk quality of ewes of two strains of Merino, strong-wool (S) and medium-wool Peppin (B), and of two breeds, strong-wool Merino and Corriedale (C). The strains were compared in two ways – for ewes suckling single lambs and for ewes suckling a pair of twins containing one lamb of each strain, and the breeds were compared for ewes suckling single lambs. The strain comparisons were made in 1960–61 and the breed comparison in 1961–62. Ewes of the S and B strains during the first 10 weeks of lactation had milk with mean fat percentages of 6.0 and 6.5 respectively when suckling singles, and 6.4 and 7.2 when suckling twins. The corresponding percentages for solids-not-fat (S.N.F.) for the period 45–72 days after parturition were 9.5 and 9.3 for singles, 9.9 and 10.2 for twins. The C breed and the S strain yielded milk with respective mean fat percentages of 8.6 and 9.4, and mean S.N.F. of 10.1 and 10.6, during the first 20 days of lactation. The only statistically significant difference among these breed and strain comparisons was the breed difference in S.N.F. In Merino ewes suckling twins the fat percentage was higher than in those suckling singles over 10 weeks of lactation (6.8 v. 6.2), while the percentage of S.N.F. for the period 45–72 days after parturition was also higher (10.1 v. 9.4). The difference in fat was not significant, but the difference in S.N.F. was. When adjusted for the higher amount of whole milk produced by ewes suckling twins, the relative amounts of fat and S.N.F. secreted become 116 : 100 and 112 : 100. There is thus a suggestion that the extra sucking stimulus which leads to a greater production of whole milk also increases the secretion of fat and S.N.F. When the 10-week lactation period was divided into three subperiods, the fat percentages showed a significant increase with time since parturition for Merino ewes suckling singles (5.7 : 5.8 : 7.2) or twins (5.7 : 6.8 : 7.9). Even when these figures were adjusted for amount of whole milk, the relative total amounts of fat secreted were 100 : 105 : 102 and 100 : 111 : 104. Lamb growth rate was no more highly correlated with the constituents of milk quality than with the total amount of whole milk. No important differences in milk quality were found between the genetic groups examined, but these were all related, the Corriedale breed being half Merino. The possibility remains that breeds differing more widely in their genetic background might also differ in milk quality.

Background: Stroke is a brain disease where an acute nerve function is occurred due to the cerebral vascular disorders. To establish a diagnosis the stroke, it can be identified by employing the Diffusion Weighted Imaging (DWI) sequence in the MRI examination. Artifacts still exist on the MRI image which in turn reduce the resolution when using the DWI sequence. Adding the PROPELLER data acquisition method in the DWI sequence possibly improves the quality of brain images. The purpose of this study is to know the difference on the quality of anatomical image information between the DWI sequences with PROPELLER and without PROPELLER methods, and to determine adequate anatomical image appearance that created in amongst of the two methods, specifically for the stroke disease.Methods: this research is quantitative research with experimental approach. This study was conducted using MRI 1.5 T at Bethesda Hospital Yogyakarta. Data were 16 images from 8 patients using DWI sequences using PROPELLER without PROPELLER on MRI Brain examination with stroke. The results of the image were evaluated on 7 criteria: cortex cerebri, basal ganglia, thalamus, pons, cerebellum, stroke (infarction) and artifacts using questionnaires given to 3 respondents. Data analysis was done by Wilcoxon test to know the difference of anatomical image information on DWI sequence using PROPELLER without PROPELLER and to know better anatomical image information from both sequences seen from mean rank value.Results: The results shown, there is a significant difference on the quality of anatomical image information and the artifacts between the use of DWI sequence with and without PROPELLER methods ( 0.05). Based on the mean rank results, the DWI PROPELLER sequence has a higher mean rank value 4.50 compared to the DWI sequence without PROPELLER 0.00.Conclusions: The DWI PROPELLER sequence has better image results compared to the DWI sequence without PROPELLER.
