Background: In elderly there are changes both in gait and balance, muscle strength decline, and slowing of sensory and motoric integration by central nervous system. On the other hand, elderly are susceptible to vitamin D deficiency which is known associated with musculosceletal system in the light of functional mobility in order to perform daily Iiving activities independently. Study on vitamin D and its correlation with basic functional mobility in elderly women has not been conducted yet.

Objective: to determine vitamin D serum concentration, the timed up and go (TUG) test score, and the correlation between vitamin D serum concentration and TUG test score of elderly women.

Method: a correlative cross sectional study of institutionalized elderly women age 60 years old or greater was conducted in three nursing homes in DKI Jakarta and one nursing home in Bekasi in January 2005. TUG test was.performed to evaluate basic functional mobility by measuring the time in seconds to stand from 46 cm height armchair, walk three meters, turn around, and return to full sitting in chair. Vitamin D serum concentration was measured by ELISA method. Calcium ion serum concentration that was measured by NOVA method, age and body mass index (BMI) were confounding variables.

Result: Of forty-two elderly women who met the inclusion and exclusion criteria, thirty subjects which proportional randomly assigned were participated in this study. Mean (SD) vitamin D serum concentration was 68.0 (SD 21.1) nmoUL, with concentration S50 nmolIL was 23.3%, TUG score was 10.7 (SD 2.1) seconds, BMI was 223 (3.7) kglm2, age was 70.2 (SD 6.4) years, and median (minimal-maximal) ionized calcium serum concentration was 1.095 (1.030-1.230) mmolfL. Vitamin D serum concentration had not shown significant correlation yet with TUG (r = -0.008; p = 0.968). There were also no significant correlation among the confounding variables and TUG. The correlation with TUG for BMI r = 0.014; p = 0.942, ionized calcium serum concentration p = 0.287; p = 0.124, and age r=0.315;p=0.09.

Conclusion: The mean vitamin D serum concentration of elderly women in this study was 68.0 (SD 21.1) nmolIL, 23.3% had vitamin D deficiency, while the rest of other subjects still had normal vitamin D serum concentration. The mean TUG score of elderly women in this study was 10.7 (SD 2.1) seconds, more than half (60%) had TUG score 10-<20 seconds which means they were mostly independent to perform daily living activities. Vitamin D serum concentration had not shown significant correlation yet with basic functional mobility of elderly women, the higher vitamin D serum concentration was not followed by lesser time to perform TUG test; the proportion of subjects with TUG score <10 seconds (freely mobile in functional mobility) were lesser in vitamin D deficiency respondents."

Background: Nowadays, the role of vitamin D in various chronic diseases is a matter of great interest. Vitamin D is thought to have an immunomodulatory effect so it is thought to be associated with several allergic and autoimmune diseases, including chronic urticaria. There have been reports of low vitamin D levels in patients with chronic urticaria and vitamin D supplementations has been shown to improve symptoms of chronic urticaria which was assessed by a validated questionnaire Urticaria activity score 7 (UAS7). However, data on the correlation between serum vitamin D levels and disease activity in chronic urticaria are still limited, especially in Indonesia.

Objective: To analyze the correlation between vitamin D (25[OH]D) serum and disease activity in chronic urticaria patients.

Methods:

This is an analytic-descriptive cross-sectional study. Thirty chronic urticaria patients age 18 – 59 years old who meet all inclusion and exclusion criterias were recruited in this study. Assessment of disease activity using UAS7 and measurement of 25(OH)D serum levels were performed. Correlation of 25(OH)D serum levels and disease activity was done using Spearman analysis. In this study, an assessment of sun exposure adequacy was carried out using a weekly sunlight exposure questionnaire.

Results: The mean of UAS7 was 14.63±7.8, median duration of illness was 12 (2 – 120) month, median weekly sunlight exposure score was 8 (2 – 34), and the median serum 25(OH)D was 12.10 ng/mL (6.85 – 29.87). The majority of subjects had vitamin D deficiency (80%). There was no correlations between serum 25(OH)D levels and disease activity (r=0.151; p=0.425). However, a significant negative correlation was found in severe deficiency vitamin D group (r=-0.916; p=0.001). There was also significant moderate correlation between disease activity and duration of illness (r=0.391; p=0.033). In weekly sunlight exposure questionnaire, we found that body surface area score was significantly different between insufficiency and deficiency vitamin D groups (p=0,031).

Conclusion: There was no correlation between serum 25(OH)D levels and disease activity in chronic urticaria patients, however there was a tendency of increasing disease activity in severe deficiency vitamin D group"

"Latar Belakang: Infeksi daerah operasi (IDO) merupakan salah satu komplikasi pascaoperasi tersering yang meningkatkan morbiditas, mortalitas, dan beban biaya kesehatan. Penerapan strategi pencegahan hanya menurunkan sedikit angka infeksi nosokomial pada pembedahan. Vitamin D diketahui memiliki pengaruh pada regulasi imun dan penyembuhan luka. Namun, hanya sedikit studi yang menilai efek potensialnya dalam mengurangi kejadian IDO dengan hasil yang didapatkan belum konsisten. Penelitian ini bertujuan untuk menilai hubungan status vitamin D serum praoperasi dengan kejadian IDO pascalaparotomi elektif.Metode: Studi kohort prospektif ini dilakukan pada subjek berusia 18–65 tahun di RS pendidikan tersier, RSUPN Dr. Cipto Mangungkusumo, yang dirawat untuk laparotomi elektif pada bulan Maret hingga Juni 2023. Pengukuran 25-hidroksi vitamin D serum praoperasi menggunakan metode chemiluminescent microparticle immunoassay (CMIA) dengan cutoff defisiensi pada kadar <30 ng/mL. Penegakkan diagnosis IDO berdasarkan kriteria Centers for Disease Control and Prevention dilakukan melalui pemantauan harian selama 30 hari pascaoperasi. Analisis bivariat dan multivariat digunakan untuk menilai hubungan antara variabel bebas dan terikat, serta mengidentifikasi faktor perancu lain yang berhubungan dengan IDO. Hasil: Dari total 117 subjek penelitian, sebanyak 90,4% subjek defisiensi vitamin D dan 20,5% subjek mengalami IDO. Defisiensi vitamin D praoperasi signifikan meningkatkan risiko kejadian IDO dibandingkan tidak defisiensi (RR 1,16, 95% CI 1,07–1,26). Analisis lanjutan dengan regresi logistik untuk faktor perancu lain memeroleh bahwa status albumin serum praoperasi menjadi faktor yang paling signifikan meningkatkan risiko kejadian IDO.Kesimpulan: Terdapat hubungan yang bermakna secara statistik antara defisiensi vitamin D serum praoperasi dengan kejadian IDO pascalaparotomi elektif.

Background: Surgical site infection (SSI) is one of the most common postoperative complications that increases morbidity, mortality, and healthcare costs. The implementation of preventive strategies has only resulted in a slight reduction in nosocomial infection rates in surgical procedures. Vitamin D is known to have an influence on immune regulation and wound healing. However, there have been few studies assessing its potential effect in reducing the incidence of SSI, and the results obtained so far have been inconsistent. This study aims to assess the relationship between preoperative serum vitamin D status and the occurrence of SSI after elective laparotomy.

Methods: This prospective cohort study was conducted on subjects aged 18–65 years at a single tertiary teaching hospital, RSUPN Dr. Cipto Mangunkusumo, who underwent elective laparotomy from March to June 2023. Measurement of preoperative serum 25-hydroxy vitamin D was done using the chemiluminescent microparticle immunoassay (CMIA) method with a deficiency cutoff at levels <30 ng/mL. The diagnosis of SSI was based on the Centers for Disease Control and Prevention criteria through daily monitoring for 30 days postoperatively. Bivariate and multivariate analyses were used to assess the relationship between independent and dependent variables and identify other confounding factors associated with SSI. 

Results: Out of a total of 117 study subjects, 90.4% were vitamin D deficient, and 20.5% developed SSI. Preoperative vitamin D deficiency significantly increased the risk of SSI compared to non-deficiency (RR 1.16, 95% CI 1.07–1.26). Further analysis using logistic regression for other confounding factors revealed that preoperative serum albumin status was the most significant factor in increasing the risk of SSI.

Conclusion: There is a significant statistical association between preoperative serum vitamin D deficiency and the occurrence of SSI after elective laparotomy."
