CYP2C19 polymorphism plays an important role in clopidogrel metabolism. The genetic factor is VerifyNow P2Y12 is an examination that specifically describes platelet function against P2Y12 inhibitors. It is unknown whether platelet reactivity measured by P2Y12 reaction unit (PRU) is affected by CYP2C19 polymorphism or predictive of TIMI flow in Asian populations, particularly in Indonesia. We sought to define whether polymorphisms on CYP2C19 genes and platelet reactivity may affect the myocardial perfusion.

STEMI patients who underwent primary PCI and has received 600 mg loading dose of clopidogrel were recruited for the study. We measured platelet reactivity by VerifyNow P2Y12, high platelet reactivity was defined as > 208 PRU. Genetic polymorphisms analysis to assess the presence of CYP2C19*2 and *3 alleles on each patient were performed by Taqman method.

There were 90 patients recruited for study. Genetic polymorphisms studies revealed 23.3% of patients with *2 allele, 11.2% of *3 allele carriers, and 1.1% carried both allele. 23.4% of patients were clopidogrel non-responders. Overall, there was no correlation between CYP2C19 polymorphism and TIMI flow < 3, but there was a relationship between CYP2C19 polymorphism and decreased function of platelet inhibition (OR 4.7, p = 0.030). Platelet reactivity index > 208 increased the risk of suboptimal reperfusion (OR 3.3, p = 0.046).

There is no direct relationship between CYP2C19 polymorphism and TIMI flow, but patients with CYP2C19*2 and/or CYP2C19*3 had increased risk of being clopidogrel non responders. After adjusted to confounding factors, VerifyNow > 208 PRU is associated with suboptimal myocardial reperfusion."

"Infertilitas adalah keadaan dimana selama 12 bulan atau lebih hubungan seks tanpa proteksi tidak dapat menghasilkan keturunan. Di Indonesia sendiri masalah ini didasari oleh faktor dari pihak lelaki sebanyak 25%. Infertilitas pada pria dapat disebabkan oleh faktor internal dan eksternal. Faktor internal antara lain adalah faktor genetik. Salah satu dari faktor genetik adalah mutasi pada gen yang mengkode enzim Methylenetetrahydrofolate Reductase (MTHFR), yang merupakan enzim yang berperan penting dalam proses spermatogenesis. Mutasi ini terdapat pada posisi 677 yaitu perubahan alel C menjadi T yang disebut juga polimorfisme. Penelitian cross-sectional ini bertujuan untuk membuktikan apakah ada hubungan antara polimorfisme gen MTHFR SNP C677T dengan Oligozoospermia. Teknik yang digunakan pada penelitian ini adalah PCR-RFLP untuk isolasi dan amplifikasi DNA. Proses cutting DNA menggunakan enzim HinfI. Selanjutnya data dianalisis menggunakan perhitungan chi-square. Didapat hasil cutting 3 genotip (CC, CT, TT) yang menunjukkan bahwa ada hubungan bermakna antara distribusi ketiga genotip gen MTHFR C677T dan Oligozoospermia dengan p value 0.011 (p<0.05). Hasil serupa ditemukan juga pada distribusi alotip (alel C dan T) yang menunjukkan bahwa ada hubungan bermakna antara distribusi alotip dan Oligozoospermia dengan p value 0.005 (p<0.05). Dapat disimpulkan bahwa polimorfisme gen MTHFR pada posisi C677T berhubungan dengan terjadinya oligozoospermia pada pria Indonesia.

Infertility is a condition in which 12 months or more unprotected sex fail to produce offspring. In Indonesia this condition is dominated by male infertility with the rate of 25% of all infertility cases. Male infertility can be due to internal and external factors. Internal factors include genetic factors. One of the genetic factors is mutation in gene that codes for Methylenetetrahydrofolate Reductase (MTHFR) enzyme, which is an enzyme that plays an important role in spermatogenesis process. This mutation is located in position 677, which changed allele C into T, called polymorphism.

This cross - sectional study aims to prove whether there is any association between MTHFR gene polymorphism C677T SNP and Oligozoospermia. PCR - RFLP was used for the isolation and amplification of DNA. The DNA cutting process uses Hinf1 enzyme. Furthermore, the data were analyzed with the chi - square calculations.

As a result 3 genotype cutting were obtained (CC, CT, TT) which indicates that there is a significant association between the distribution of the three genotypes of MTHFR C677T and Oligozoospermia genes with p value of 0.011 (p<0.05). Similar results were also found on the allotype distribution (allele C and T) that indicates that there is a significant association between the allotype distribution and Oligozoospermia with p value of 0.005 (p<0.05). In conclusion, MTHFR gene polymorphism C677T is associated with the occurrence of Oligozoospermia in Indonesian men."

"Kejadian stunting pada masa anak-anak masih menjadi masalah kesehatan masyarakat, khususnya di negara berkembang seperti Indonesia. Berdasarkan data Riset Kesehatan Dasar (Riskesdas, 2013) prevalensi stunting pada anak usia 5-12 di Indonesia sebesar 30,7%. Faktor nutrisi telah diketahui sebagai penyebab kejadian stunting. Namun, beberapa penelitian menemukan adanya kontribusi genetik terhadap penyerapan kalsium yang akan mempengaruhi pertumbuhan, yaitu gen vitamin D receptor (VDR). Tujuan dari penelitian ini adalah untuk mengetahui hubungan antara faktor genetik dan nutrisi terhadap height-for-age Z-core (HAZ) pada anak sekolah dasar di kabupaten Malang, Jawa Timur. Penelitian ini menggunakan desain studi potong lintang dan dilakukan pada tahun 2018. Penelitian ini melibatkan 142 anak sekolah dasar berusia 8-10 tahun. Pengukuran tinggi badan dilakukan untuk menghitung HAZ pada anak-anak. Asupan energi, protein, kalsium dan vitamin D diperoleh dengan 24-hour dietary recall selama 4 hari. Dua SNP yang terletak pada daerah promoter dari gen VDR dipilih (rs11568820 dan rs4516035); dan distribusi genotipnya dianalisis menggunakan Real Time PCR. Faktor lain seperti karakteristik sosiodemografi, riwayat penyakit menular dan skor paparan sinar matahari diperoleh dengan kuesioner terstruktur, dan kuesioner paparan sinar matahari. Hasil penelitian menunjukkan bahwa prevalensi stunting sebesar 21,8%. Asupan makan sebagian besar kurang terpenuhi, khususnya asupan kalsium dan vitamin D. Distribusi genotip rs11568820 adalah TT (19%), CT (43,7%) dan CC (37,3%). Sedangkan distribusi genotip rs4516035 adalah TT (90,8%) dan CT (9,2%). Analisis bivariat menunjukkan adanya korelasi yang signifikan antara asupan energi dan protein terhadap HAZ (p=0,030 dan p=0,016), tetapi tidak pada asupan kalsium dan vitamin D. Selain itu, tidak ditemukan hubungan yang signifikan antara polimorfisme kedua SNP gen VDR dengan HAZ (p>0,05). Setelah disesuaikan dengan faktor-faktor lainnya, asupan protein secara signifikan berkolerasi dengan HAZ (β=0,034, 95% CI 0,016 – 0,053, p<0,001, adj. R2=0,077). Efek dari aktivitas gen VDR kemungkinan tidak terlihat karena rendahnya asupan vitamin D yang diperlukan untuk meningkatkan penyerapan kalsium yang kemudian akan mempengaruhi HAZ.

Childhood stunting remains as a major public health problem, especially in developing countries such as Indonesia. According to Indonesia Basic Health Research (Riskesdas, 2013) the prevalence of stunting among children aged 5-12 years old in Indonesia was 30.7%. Nutrition factors has been known as a predominant factors associated with stunting. However, some studies discovered a genetic contribution in calcium absorption that will affect growth of the children, known as vitamin D receptor (VDR) gene. The aim of this present study was to assess the association between genetic and nutritional factors related to height-forage Z-score (HAZ) of elementary school children in Malang District, East Java. The study design was a cross-sectional study which began on 2018. In this study, 142 children aged 8-10 years old were included. Height measurement was obtained to calculate HAZ of the children. Dietary intake consist of energy, protein, calcium and vitamin D intake were obtained using 4 days 24-hour dietary recall. Two SNPs located in the promoter region of VDR gene were selected (rs11568820 and rs4516035); its genotype distribution were analyzed using Real Time PCR system. Other factors such as sociodemographic characteristics, history of infectious diseases and sun exposure score were assessed using structured questionnaire and sun exposure questionnaire. The result showed that the prevalence of stunting was 21.8%. Dietary intake were mostly inadequate, especially for calcium and vitamin D intake. Genotype distribution of rs11568820 was TT (19%), CT (43.7%), and CC (37.3). While for rs4516035 the distribution was TT (90.8%) and CT (9.2%). Bivariate analysis showed a significant correlation between energy and protein intake with HAZ of the children (p=0.030 and p=0.016, respectively), but not with calcium and vitamin D intakes. There were no significant association between VDR gene polymorphism for both SNPs and HAZ of the children (p>0.05). Adjusted by other factors, protein intake was significantly correlated with HAZ (β=0.034, 95% CI 0.016 – 0.053, p<0.001, adj. R2=0.077). The effect of VDR gene promoter activity might not revealed due to very low vitamin D intake to stimulates intestinal calcium absorption which in turn affect HAZ.
