Background: Absolute grip strength (aGS) is  used to detect dynapenia, and is also an  indicator of functional impairments such as mobility limitations. The objective of this study is to investigate whether dynapenia status assessed by absolute grip strength (aGS) is associated with loss of community mobility.Method: The population studied (n=62) was composed of  a dynapenic group of women (aged 66.4 ± 4.8) according to an aGS threshold of ≤ 19.9kg and an age-matched group of nodynapenic women (aged 66.1 ± 5.2). The aGS was measured and body-weigth-related to grip strength (BW/GS) was computed. Fonctionnal laboratory tests were conducted. During 12 days, each participant wore a GPS device to obtain Transit distance in vehicle per day, Transit distance on foot per day and Ellipse area.  The Life space (LS) was assessed using the Life Space Assesment questionnaire (LSA). A Wilcoxon test was used to compare the 2 groups for the community mobility measures. Then, data of the 2 groups were pooled to assess the relationship between BW/GS and community mobility measures. A Spearman correlation was used.Results: The dynapenic group performed worse for fonctionnal capacity tests such as the step test and the walking speed. Howerver, no significant difference was found for GPS measures and LS between the two groups. No significant relationship was found for the BW/GS and community mobility measures with the GPS measures and the LS.

AbstractThe stake test is widely used to evaluate the efficacy of wood preservatives. This test monitors the deterioration level observed in treated stakes partially inserted into the ground. The results are conventionally expressed as the relationship between deterioration levels and exposure periods. The preservative efficacy is compared among the stake groups treated with different retention levels based on the test results; however, there is no scientific basis for the comparison. We applied survival analysis to the conventional stake test to include a scientific basis to the test. Stakes impregnated with different types and retention levels of preservatives were subjected to deterioration at two test sites for approximately 30 years. The deterioration levels were monitored according to the conventional procedure and survival analysis was applied to the monitored data. Kaplan–Meier plots of the survival probabilities against the exposure periods indicated that there is a significant difference between the durability of the stakes treated with alkylammonium chloride (AAC-1) at K2 and K3 retention levels, whereas no significant difference was observed between those at K3 and K4 retention levels. Contrastingly, emulsified copper naphthenate (NCU-E) was found to be a reliable preservative, and the stakes impregnated with NCU-E showed a significant increase in durability in accordance with preservative retention. Alkaline copper quaternary (ACQ-1) also appeared to be a reliable preservative; however, the increase in stake durability after ACQ-1 treatment differed between the test sites. These results were verified using the modified Gehan–Breslow–Wilcoxon test with Holm’s p adjusting method.

Purpose:To quantify the influence of the assistive pole, seat configuration, and upper-body and trunk strength on seated-throwing performance in athletes with a spinal-cord injury (SCI).Methods:Ten Paralympic athletes competing in wheelchair rugby, basketball, or athletics (seated throws) participated in 2 randomized sessions: seated throwing and strength tests. Participants threw a club from a custom-built throwing chair, with and without a pole. 3D kinematic data were collected (150 Hz) for both conditions using standardized and self-selected seat configurations. Dominant and nondominant grip strength were measured using a dynamometer, and upper-body and trunk strength were measured using isometric contractions against a load cell.Results:Seated throwing with an assistive pole resulted in significantly higher hand speed at release than throwing without a pole (pole = 6.0 ± 1.5 m/s, no pole = 5.3 ± 1.5 m/s; P = .02). There was no significant difference in hand speed at release between standardized and self-selected seating configurations during seated throwing with or without an assistive pole. Grip strength (r = .59–.77), push/pull synergy (r = .81–.84), and trunk-flexion (r = .50–.58) strength measures showed large and significant correlations with hand speed at release during seated throwing with and without an assistive pole.Conclusions:This study has demonstrated the importance of the pole for SCI athletes in seated throwing and defined the relationship between strength and seated-throwing performance, allowing us to better understand the activity of seated throws and provide measures for assessing strength that may be valid for evidence-based classification.

Background: Normal nutritional status is a balanced condition of nutritional intake and requirement in a person. Lack of nutrition in cancer patients promotes undesirable effects on various organs and systems of the body. Purpose: To determine the nutritional status differences in patients with advanced stage NPC type III WHO before and after radiotherapy,  and the relationship between nutritional status with mucositis occurance after radiotherapy. Method: Observational analytic study. Sampling was conducted by non-random purposive sampling technique with 10 subjects with NPC. The statistical analysis used paired sample Wilcoxon test and Spearman correlation test. Result: The study found significant differences between nutritional state regarding BMI, LOLA and transferrin before and after radiotherapy with p<0.05. Paired sample t test of BMI, LOLA, transferrin before and after radiotherapy demonstrated BMI p=0.000, LOLA p=0.001 and transferrin p=0.005. The paired sample t test for albumin before and after radiotherapy showed that radiotherapy did not cause significant decrease in albumin. Correlation test to determine the relationship among BMI, LOLA, albumin, and transferrin before radiotherapy with mucositis occurance showed BMI p=0.062, LOLA p=0.209, p=0.904 albumin, transferrin p=0.631 which meant that nutritional state has no corelation with mucositis occurance. While after radiotherapy it showed BMI p=0.122, p=0.209 LOLA, albumin, p=0.902 and transferrin p=1.000 which meant that nutritional state after radiotherapy has no corelation to the occurance of mucositis. Conclusion: Radiotherapy in patients with advanced-stage of NPC caused a significant difference in nutritional state before and after radiotherapy, but had no significant association with mucositis occurance. Keywords: nasopharyngeal carcinoma, radiotherapy, nutritional state, malnutrition, mucositis Abstrak :  Latar belakang: Status nutrisi normal menggambarkan keseimbangan yang baik antara asupan nutrisi dengan kebutuhan nutrisi.

Abstract The relationship between anthropometric and physical characteristics of female handball players and throwing velocity is considered an important factor in handball performance. The aim of this study was to examine key differences in anthropometric and fitness characteristics between top elite and elite female players competing in the first Spanish handball league. A total of 89 players from the first Spanish handball league were divided into two groups, top elite (38) and elite (51) players, and assessed for anthropometric and fitness characteristics (throwing velocity, vertical jump and hand grip strength). A Student’s t-test was used to determine whether a statistically significant difference between the two different levels of play occurred. Significant differences were found in age, body height, body mass, arm span, muscle mass, different girths (tensed and flexed arm, forearm, wrist, ankle), dominant hand width and length, different breadths (biacromial, bitrochanteric, bistyloid breadth and biepicondylar humerus) and fitness characteristics (hand grip strength and throwing velocity for different positions). Top elite players compared to elite players showed differences in anthropometric characteristics which were mainly located in the upper limbs and mostly were nonmodifiable aspects by training. Furthermore, the best players were able to maintain a high throwing velocity in different tactical situations.

The important task for modern physiology is remote monitoring of the functions of physiological systems of the human organism during the competitive and training activity. It is well known that analysis of heart rate variability is one of the effective methods to evaluate the physiological changes which occur in the response to physical loads. In order to perform the correct analysis of heart rate variability by newly designed devices, it is necessary to confirm the sufficient level of accuracy in the registration of RR intervals. The purpose of our research was to analyze the accuracy of RR time series measurements by software-hardware complex “Rytm” and validity of subsequently calculated heart rate variability indexes in conditions of exercise performance. Material and methods. The study involved 20 healthy male adults 20-21 years old. Recording of cardio intervals was performed simultaneously with «Polar RS800», and software-hardware complex “Rytm”. The subjects performed a step test in a rate of 20 steps per minute, platform height – 40 cm, duration – 2 minutes. Results and discussion. Heart rate variability indexes were calculated by Kubios HRV 2.1 software. The totally 4707 pairs of RR intervals were analyzed. The average bias between the RR interval, registered by software-hardware complex «Rytm» and «Polar RS800», was only 0.06 s. We revealed the narrow Bland–Altman limits of agreement (3.72 − -3.83 ms) and the highest value of the intraclass correlation coefficient (1.000) between the data of these two devices. The Bland–Altman plot confirmed good agreement between the devices in the measurements of RR intervals. At the same time, the significant difference (p = 0.002) of the two data sets was found according to paired Wilcoxon test. As the final goal of the registration of RR time series is calculation of individual heart rate variability indexes, we intended to test the presence of substantial differences in the heart rate variability indexes, derived from the data from two devices − «Polar RS800» and software-hardware complex «Rytm». We compared the results of time-domain (HR, STD RR, RMSSD, pNN50), frequency-domain (VLF, LF, HF, LF / HF) and nonlinear (RR tri index, SD1, SD2) analysis of heart rate variability. It was found that only for the LF/HF ratio a statistically significant difference was present. Conclusion. The results suggest the good agreement between most of the heart rate variability indexes based on data of software-hardware complex «Rytm» and well approved heart rate monitoring systems («Polar RS800»)

Summary Aim: Tumor scintigraphy with 201-TICI is an established diagnostic method in the follow-up of differentiated thyroid cancer. We investigated the relationship between thyroglobulin (Tg) level and tumor detectability. Subject and methods: We analyzed the scans of 122 patients (66 patients with proven tumor). The patient population was divided into groups with Tg above (N = 33) and below (N = 33) 5 ng/ml under TSH suppression or above (N = 33) and below (N = 33) 50 ng/ml under TSH stimulation. Tumor detectability was compared by ROC-analysis (True-Positive-Fraction test, specificity 90%). Results: There was no significant difference (sensitivity 75% versus 64%; p = 0.55) for patients above and below 5 ng/ml under TSH suppression and a just significant difference (sensitivity 80% versus 58%; p = 0.04) for patients above and below 50 ng/ml under TSH stimulation. In 18 patients from our sample with tumor, Tg under TSH suppression was negative, but 201-TICI-scan was able to detect tumor in 12 patients. Conclusion: Our results demonstrate only a moderate dependence of tumor detectability on Tg level, probably without significant clinical relevance. Even in patients with slight Tg elevation 201-TICI scintigraphy is justified.

ABSTRACT Toilet training is an effort to train children to be able to control and urinate (BAK) and defecate (BAB). Toilet training is one of the main tasks of children at toddler age. Toilet training is one of the main tasks of children in toddler age which is very important to be done to create independence in children in controlling BAK and BAB and children know the parts of the body and their functions. Data in 2012 shows that ± 60% of parents do not teach toilet training to children from an early age. The aim of the study was to find out the effectiveness of toilet training education on maternal behavior and toilet skills in toddler age training (18-36 months). The study was conducted in July-August 2018. This type of quantitative research used the design of the Quasy pretest and posttest experiment with non-equivalent control group design. Samples were 36 mothers and 36 children with purposive sampling technique. Data analysis used Paired t test, Wilcoxon test, Man-Whitney test an Independent t test. The results showed that toilet training education through lecture methods, modules and maze games was more effective than toilet training education through lecture and leaflet methods on children's knowledge and abilities. Conversely, for the role of mothers in supervision there is no significant difference in effectiveness. Health education is recommended in health promotion programs to increase maternal knowledge, the role of mothers and the ability of toilet training children independently. Keywords: Toilet training, Lecture method, Module, Maze game, Leaflet, Knowledge, Role of mother, Children's ability.
