Stunting is a condition of impaired growth and development that children experience caused by low nutrional intake, starting from fetus until the first 1,000 days of life. One indicator that cause malnutrition is a lack of Vitamin C. Vitamin C is a water-soluble vitamin and excreted in the urine. A urine Vitamin C level less than 1.12 mmol/L, indicates that the patient is deficient in Vitamin C intake. Therefore, early detection is needed to monitor adequate intake of Vitamin C in pregnant women. In this study, a colorimetric system was developed for predict Vitamin C contents in urine using image-based classification and regression models with urine test strip. The image was captured using the Samsung Galaxy A72, Samsung Galaxy A31, Huawei Nova 5T, and Vivo Y12 smartphone cameras. The image acquisition process uses an image housing box contains a reference color board that refers to the X-Rite Color Checker Classic and a test barcode. The test barcode is a transformation of the urine test strip by cutting the strip into two equal parts. The Polynomial Color Correction (PCC) color correction model is applied to the image before entering the CNN models. The architecture of the Convolutional Neural Network (CNN) model used is VGG16. Variations in the input image form were carried out to determine the most suitable image form for the colorimetric system, in case study of Vitamin C urine. Variations of input image form including single analyte image, multiple analyte image, all analyte image, and urinalysis barcode image. The urinalysis barcode image is a combination of the test barcode and the reference color. The results showed that the best model was obtained using the form of urinalysis barcode input image. CNN-VGG16 can perform color correction and feature extraction in the model. The system outputs are 5 classes of urine Vitamin C contents and Vitamin C contents of urine. Experiments were carried out with 3500 images using artificial urine samples and 680 images using real urine samples. The performance of the CNN-VGG16 classification model was obtained with an accuracy of 99.5% using artificial urine and 88.7% using real urine samples. The performance of the CNN-VGG16 regression model was obtained with an R2 value of 0.998 and an RMSE of 0.067 using artificial urine, as well as an R2 value of 0.930 and an RMSE of 0.457 using real urine. This performance indicates that the urinalysis colorimetric system can be used to determine the class of urine Vitamin C contents and measure urine Vitamin C contents."

Background. Septic and septic shock patients will have organ dysfunctions due to free radical reaction with microvacular endothelial cells, thus morbidity and mortality rate will increase in these conditions. Those organ dysfunctions can be measured through the changes of Interleukin-6 (IL-6) levels, C-Reactive Protein (CRP) levels, and Sequential Organ Failure Assessment (SOFA) scores. The administration of ascorbic acid has a feature known as free radical scavenging. The feature is expected to reduce the inflammatory rate in the organs and to improve the functions. This study was aimed to analyze the intravenous administration effect of 6 grams of ascorbic acid towards the changes of Interleukin-6 levels, C-Reactive Protein levels, and SOFA scores in septic and septic shock patients in intensive care unit

Methods. This was a single blind randomized controlled clinical trial study on patients aged 18-65 years old with septic and septic shock conditions in the first 24 hour care in intensive care unit (ICU) Dr. Cipto Mangunkusumo Hospital-Jakarta and H. Adam Malik Hospital-Medan from July to December 2019. In total, 49 subjects were included in the study and randomized into two groups. Intervetion group (n=23) received 1.5 gram/6 hours of vitamin C in three days consecutively, whereas the control group (n=26) did not receive the vitamin C. Measurements of IL-6 levels, CRP levels, and SOFA scores were performed in the 24th, 48th, and 72th hour.

Results. There were no significant changes of IL-6 levels (p=0.423), CRP levels (p=0.080), and SOFA scores (p=0.809) between the two groups.

Conclusion. The intravenous administration of 6 grams of ascorbic acid did not significantly affect the changes of Interleukin-6 levels, C-Reactive Protein levels, and SOFA scores in septic and septic shock patients in intensive care unit."

"Serat asbes yang terinhalasi masuk ke dalam alveolus menyebabkan terjadinya peningkatan produksi reactive oxigen spesies (ROS) yang dapat memicu terjadinya reaksi inflamasi. Interleukin 6 merupakan penanda reaksi inflamasi akibat pajanan serat asbes. Vitamin C dan E merupakan antioksidan yang bekerja sebagai scavenger ROS. Vitamin C juga dapat menghambat aktivitas faktor transkripsi NFқB. Vitamin E selain dapat menghambat aktivitas faktor transkripsi JAK/STAT3 dan NFқB, juga dapat menghambat aktivitas COX2 dan LOX5. Penelitian potong lintang di sekretariat serikat buruh pabrik asbes X Kabupaten Karawang bulan Oktober 2014 dilakukan untuk menilai korelasi asupan vitamin C, E dengan kadar interleukin 6 pada pekerja pabrik asbes. Lima puluh dua pekerja pabrik asbes berhasil menyelesaikan protokol penelitian. Hasilnya menunjukkan tidak terdapat korelasi bermakna (p >0,05) antara asupan vitamin C dengan kadar IL-6 dan antara asupan vitamin E dengan kadar IL-6. Terdapat korelasi positif antara kadar vitamin C dengan kadar IL-6 (r = 0,31) dengan p <0,05, namun tidak terdapat korelasi antara kadar vitamin E dengan kadar IL-6.

Asbestos fibers that are inhaled into the alveoli cause increased production of reactive oxygen species (ROS) which may trigger inflammation reaction. Interleukin 6 (IL-6) is a marker of inflammation reaction caused by asbestos fibers exposure. Vitamin C and vitamin E are antioxidants acting as ROS scavengers. Vitamin C can also inhibit the activity of transcription factor NFқB. Vitamin E can inhibit the activities of transcription factors JAK/STAT3 and NFқB as well as the activities of COX2 and LOX5.

A cross-sectional sudy at a labor union secretariat in Karawang Regency in October 2014 was conducted to evaluate the correlations between intakes and levels of vitamin C and vitamin E and level of IL-6 in asbestos factory workers. Fifty two asbestos factory workers finished the study. The result showed no significant correlation between vitamin C intake and IL-6 level or between vitamin E intake and IL-6 level. There was a moderate positive correlation between vitamin C level and IL-6 level (r = 0.31, p <0.05), but there was no correlation between vitamin E level and IL-6 level."

Drug-induced hepatitis is one of the serious side effects of anti-tuberculosis drugs (ATD) that can reduce patient compliance in tuberculosis treatment, thus increasing the risk of treatment failure or developing drug resistance. One of the proposed mechanisms is the occurrence of oxidative stress due to the formation of reactive metabolites, disruption of the mitochondrial respiration chain, and decreased antioxidant enzyme pools that can be triggered by ATD. Vitamin C is a potential antioxidant that is known to have a protective effect on drug-induced liver damage. This study aims to find the relationship between vitamin C intake and the incidence of ATD-induced hepatitis in pulmonary tuberculosis patients. A cross-sectional study was conducted at Persahabatan General Hospital from February to March 2024. A total of 108 patients who met the criteria became research subjects. Data were collected using sociodemographic questionnaire interviews, anthropometric measurements, assessment of vitamin intake with the SQ FFQ, and data on the subject's liver function laboratory results in the last 1 month. The proportion of drug-induced hepatitis in pulmonary TB patients in this study was 6.5%. The majority of subjects were male (54.6%) and had a median age of 41 years. Most of them had poor nutritional status (40.7%), with completed secondary school education (73.1%), and low income (72.2%). A total of 40.7% had comorbidities, 4.6% were HIV positive, 43.5% took other drugs along with ATD, 52.8% did not smoke, and 7.4% of subjects consumed alcohol. More than half of the subjects were in the intensive phase (56.5%) and had positive bacteriological status (50.9%). Many subjects did not take vitamin C supplements (85.2%). Most patients had low intakes of vitamins E and C (97.2% and 63.0%) with median intake values ​​were 1.20 mg/day and 66.65 mg/day. There was no relationship between vitamin C intake and the incidence of ATD-induced hepatitis (OR 3.77 95% CI 0.44-32.55, p value 0.256). There were also no factors that influenced the incidence of OAT-induced hepatitis in this study.

"Latar Belakang: Inflamasi pada kehamilan normal disebabkan oleh oksidatif stress yang disebabkan oleh produksi radikal bebas dan peningkatan biomarker inflamasi, seperti IL-6. 830 wanita meninggal setiap harinya karena hamil dan melahirkan, diantaranya 15% disebabkan oleh komplikasi pada kehamilan seperti preeklampsia. Preeklampsia merupakan sebuah sindrom yang muncul pada kehamilan, terutama pada trimester ketiga, dan terasosiasi dengan inflamasi yang berlebihan. Sebagai antioksidan, vitamin C diduga berperan menurunkan stress oksidatif pada kehamilan dan persalinan, sehingga menurunkan tingkat kematian ibu, sehingga dilakukan penelitian untuk mencari hubungan antara asupan vitamin C dan kadar IL-6 sebagai biomarker dari inflamasi. Metode: Penelitian berdesain potong- lintang dilakukan di Rumah Sakit Cipto Magunkusumo pada 40 orang ibu hamil trimester ketiga dikelompokkan menjadi preeklampsia dan non-preeklampsia. Subjek diwawancara menggunakan semi-kuantitatif food frequency questionnaire yang diolah dengan NutriSurvey untuk asupan vitamin C, dan ELISA untuk kadar IL-6. Data diuji distribusinya dengan uji normalitas Shapiro-Wilk, kemudian dilakukan analisis univariat dengan uji T tidak berpasangan, Mann-Whitney, dan Chi-square; serta bivariat dengan uji korelasi Spearman. Analisis dilakukan dengan SPSS for Windows ver. 20. Hasil: Hasil yang tidak signifikan ditunjukkan pada usia subjek dan usia gestasi terhadap preeklampsia dan non- preeklampsia dengan p=0,545 dan p=0,34. Asupan vitamin C yang ditunjukkan oleh subjek preeklampsia sedikit lebih tinggi dibandingkan dengan kelompok non-preeklampsia dengan median sebesar 76,37(28,05–396,88) mg dan 68,87(8,57–198,53) mg dengan p=0,358. Sedangkan, kelompok preeklampsia menunjukkan kadar IL-6 yang lebih tinggi dibandingkan kelompok non-preeklampsia [15,8(2,2–67,4) pg/ml vs 6,8(1,8–43,5) pg/ml] dengan perbedaan yang tidak signifikan. Uji korelasi non-parametrik menunjukkan tidak adanya asosiasi yang signifikan antara vitamin C dan kadar IL-6 (p=0,361; r= -0,147). Selain itu juga, tidak ditemukan adanya perbedaan yang bermakna antara asupan vitamin C dan kadar IL-6 untuk setiap kelompok dengan r= -0,143 dan -0,198 secara berturut-turut. Pembahasan: Tidak didapatkan hubungan yang signifikan antara asupan vitamin C dan kadar IL-6 pada ibu hamil trimester ketiga pada penelitian ini. Hasil ini dapat disebabkan oleh asupan vitamin C pada subjek yang kurang (<85 mg) pada kedua kelompok dan juga inflamasi pada trimester ketiga yang meningkat. Selain itu, penelitian ini hanya meneliti hubungan asupan vitamin C dengan kadar IL-6, sedangkan peran melawan stress oksidatif dan inflamasi melibatkan seluruh antioksidan, baik eksogen maupun endogen. Oleh karena itu, penelitian lebih lanjut mengenai hubungan antioksidan lainnya dengan IL-6 sangat disarankan.

Background: Inflammation in pregnancy is primarily caused by systemic oxidative stress due to production of free radicals and increased levels of inflammatory biomarkers such as IL-6. Every day, 830 women associated with pregnancy and childbirth die globally, approximately 15% of which is caused by prenatal complications such as preeclampsia. Preeclampsia is a syndrome developed during pregnancy which occurs mostly on the third trimester and is strongly associated with inflammation. As an antioxidant, vitamin C could potentially play a role in reducing oxidative stress in either pregnancy or delivery, thus decreasing mortality rate. Therefore, a research to investigate the relationship between vitamin C intake and levels of IL-6 as a biomarker of oxidative stress was conducted. Methods: A cross-sectional study done in Cipto Mangunkusumo National General Hospital. 40 women in third trimester pregnancy are then grouped into preeclampsia and non- preeclampsia, and surveyed via Food Frequency Questionnaire and NutriSurvey for vitamin C, as well as ELISA assay for IL-6 expression. All data was firstly analyzed using Shapiro- Wilk normality test, then analyzed univariately using unpaired T-test, Mann-Whitney, and Chi-square; bivariate analysis was conducted with Spearman correlation test. All analysis was done using SPSS software ver. 20. Results: There is no significant difference shown between mean age and gestational age of the preeclampsia and non-preeclampsia group with p=0.545 and p=0.34 respectively. Subjects in the preeclampsia group were shown to consume vitamin C slightly higher than the non-preeclampsia with median values of 76.37(28.05–396.88) mg and 68.87(8.57–198.53) mg respectively with p=0.358. On the other hand, the preeclampsia group expressed higher level of IL-6 than the non-preeclampsia [15.8(2.2–67.4) pg/ml vs 6.8(1.8–43.5) pg/ml] with no significant difference. A nonparametric correlation test showed no significant association between vitamin C (p=0.361; r = -0.147) and total IL-6 level. There was also no significant difference between vitamin C consumption and IL-6 level for each group with r= -0.143 and -0.198 respectively. Discussion: There was no significant association between vitamin C intake and IL-6 level on third trimester pregnancy women (p= 0.361). This result could be caused by inadequate intake of vitamin C in both groups and the increase of inflammation on the third trimester. In addition, this study only examined association between vitamin C and IL-6 level, while role of neutralizing oxidative stress and inflammation involved both endogenous and exogenous antioxidants. Therefore, further research should be considered to study vitamin C alongside the other antioxidants level and IL-6 level."
