A larger diameter of femoral head of artificial hip joint (AHJ) is commonly recommended for increasing range of motion (RoM) and for avoiding dislocation. Unfortunately, increasing that diameter will reduce the material liner thickness of the acetabular component. The behaviour of the AHJ contact system with thickness variation of the Ultra High Molecular Weight Polyethylene (UHMWPE) acetabular liner was studied numerically and experimentally. Finite element analysis was employed for calculating contact stresses and the wear volume was measured experimentally. Numerical results show higher contact stresses with decreasing liner wall thickness. Yet, the experimental results suggest that wear decreases as well with decreasing wall thickness. These findings are important in designing an optimised acetabular liner for larger RoM.
Background: In August 2018 Lombok Island in Indonesia was hit by a 7 Richter scale earthquake. This study aimed to assess the effectiveness of comprehensive nutrition disaster rehabilitation, based on the holistic integrated early child development concept, on the growth and development of children under five. Methods: A community-based intervention was performed in the East Lombok district; four villages in two sub-districts were randomly allocated into intervention or control groups. Mothers of 6–49-month-old children in the intervention group (n = 240) attended parenting classes (twice weekly) and received shredded fish/liver/anchovy and optimized complementary feeding/food-based recommendations, developed using linear programming. Health staff from the public health center and teachers from early childhood education (ECE) centers delivered parenting sessions on health–nutrition and care–education. The control group (n = 240) received existing health services. Indicators measured at baseline and the end line point were weight, length/height, hemoglobin, feeding practices, psychosocial care (HOME) and maternal stress (SRQ). At the end line point, child development was assessed using BSID-III. Results: At the end line point, maternal stress and child morbidity (cough) were lower and dietary diversity (+1) in 6–23-month-old children, and weight-for-age Z-score (+0.26) and social emotional score (+10 points) in ≥24-month-old children were higher in the intervention group. Conclusions: The nutrition rehabilitation intervention delivered through ECE centers has a positive effect on the growth and development of children under five in post-disaster conditions.
Latar Belakang : Pengaturan asupan karbohidrat atlet sangat penting agar dapat menjaga performa. Konsumsi sumber karbohidrat setelah latihan berguna untuk mengembalikan simpanan karbohidrat tubuh atlet yang hilang. Salah satu cara yang dianggap praktis untuk menyediakan asupan karbohidrat setelah latihan adalah dengan mengonsumsi minuman berkarbohidrat. Sari tebu merupakan cairan alami sumber karbohidrat yang sering dikonsumsi selain minuman berkarbohidrat pabrikan. Meskipun sering dikonsumsi, penelitian mengenai perbedaan kadar glukosa darah atlet setelah latihan antara sari tebu dan minuman berkarbohidrat pabrikan belum banyak dilakukan. Tujuan : Penelitian ini bertujuan untuk mengetahui perbedaan kadar glukosa darah atlet setelah latihan antara pemberian sari tebu dan minuman berkarbohidrat pabrikan..Metode : Studi eksperimental semu dengan pendekatan randomized pretest- post test 2 group design dengan 2 kelompok perlakuan pada 20 atlet sepak bola Usia 13- 16 tahun di Sekolah Sepak Bola UNDIP pada bulan Agustus 2014. Kelompok kontrol mengonsumsi minuman berkarbohidrat pabrikan, sedangkan kelompok perlakuan mengonsumsi sari tebu murni. Jumlah masing – masing cairan yang diberikan adalah 550 ml. Pemeriksaan kadar glukosa darah dilakukan 5 menit sebelum latihan, 5 menit setelah latihan dan 15 menit setelah intervensi. Latihan yang dilakukan berupa lari 2.4 km dalam waktu 10.49 – 12.10 menit.Hasil : Berdasarkan uji paired t test terdapat perbedaan yang signifikan antara kadar glukosa darah subjek setelah latihan dan setelah intervensi pada kedua kelompok baik pada kelompok kontrol maupun pada kelompok perlakuan (p<0.05). Berdasarkan uji beda independent t test tidak terdapat perbedaan yang signifikan antara selisish kadar glukosa darah setelah latihan dan setelah intervensi antara kelompok kontrol dan perlakuan (p>0.05).Kesimpulan : Konsumsi sari tebu murni dan minuman berkarbohidrat pabrikan setelah latihan mampu meningkatkan kadar lukosa darah atlet setelah latihan masing - masing sebesar 24.2 ± 28.61 dan 15.10 ± 8.69. Sari tebu mampu meningkatkan kadar glukosa darah atlet sebanding dengan minuman berkarbohidrat pabrikan dengan (p>0.05). Sari tebu dapat digunakan sebagai alternatif penyedia asupan karbohidrat setelah latihan yang sama baiknya dengan minuman berkarbohidrat pabrikan.
Background: Stunting was the impact of chronic malnutrition in the long term and has an impact on children's growth and development disorders. Stunting has become a priority for the Indonesian government, including in the Province of East Nusa Tenggara with a stunting reduction target of 14% in 2024. The Indonesian governments have made many efforts to overcome stunting. Religious leaders are parties suspected of being able to play a role in the process. This study was aimed to determine the factors that influence the role of religious leaders in supporting the process of accelerating stunting reduction in the dry land area in East Nusa Tenggara. Subjects and Method: This was a mixed-method study. This study was conducted in May 2022 using the focus group discussion (FGD) method and involved 13 religious leaders who were taken purposively. The data collected were analyzed qualitatively (making interview transcripts) and quantitatively. The independent variables were level of understanding about stunting, support for policies/programs related to stunting, stunting program budget support, national program support: CATIN facilitation, and cross-sectoral cooperation support. The statistical analysis used is multiple logistic regression analysis. Results: Factors that significantly influence the role of religious leaders are the level of understanding of religious leaders about stunting (aOR= 3.50; 95% CI= 0.12 to 12.3; p= 0.010) and support factors for cross-sectoral cooperation (aOR= 2.00; 95% CI= 1.22 to 21.10; p= 0.007). Budget support for stunting related policies/ program (aOR= 2.40; 95% CI= 1.76 to 12.32; p= 0.621), support policy/ program related to stunting (aOR= 1.70; 95% CI= 1.27 to 7.32; p= 0.387), and national program, support "CATIN Mentoring" (aOR= 1.10; 95% CI= 0.37 to 21.02; p= 0.621) were statistically non-significant. Conclusion: Factors that influence the role of religious leaders were the level of understanding of religious leaders about stunting, support factors for cross-sectoral cooperation, budget support for stunting related policies, support policy related to stunting national program, and support "CATIN Mentoring".
