"Latar Belakang: Tumor sistem saraf pusat (SSP) meningkatkan tekanan intrakranial dan menyebabkan berbagai gangguan neurologis yang dapat memengaruhi status gizi pasien. Status gizi memengaruhi imunitas bawaan dan adaptif. Pada hampir semua jenis keganasan kadar asam amino rantai cabang (AARC) didapatkan rendah. Asam amino rantai cabang meningkatkan imunitas dengan meningkatkan fagositik neutrofil, proliferasi limfosit, sintesis protein, menjaga jalur pensinyalan yang sensitif terhadap nutrisi. Rasio neutrofil limfosit (RNL) menggambarkan keseimbangan sistem imunitas dengan inflamasi. Peningkatan RNL dihubungkan dengan penurunan respon imun tubuh, terapi, harapan hidup dan prognosis. Penelitian ini dilakukan untuk mengetahui hubungan asupan AARC terhadap RNL pada pasien tumor SSP.Metode: Penelitian ini merupakan studi potong lintang pada pasien tumor SSP yang dirawat di RSCM. Karakteristik subjek berupa usia, jenis kelamin, jenis tumor, defisit neurologis, status performa karnofsky, indeks massa tubuh (IMT), status gizi berdasarkan ASPEN, penyakit komorbid, status infeksi, kemoterapi, radiasi, dan atau kemoradiasi, terapi glukokortikoid, asupan energi dan protein, asupan AARC, serta nilai RNL. Dilakukan analisis hubungan antara dua kelompok asupan AARC yang dibagi sesuai median populasi penelitian terhadap RNL.Hasil: Terdapat 66 subjek penelitian dengan median usia 48 tahun, mayoritas subjek perempuan (56,1%), dengan jenis tumor sekunder sebanyak 38 subjek (57,6%). Defisit neurologis tertinggi berupa nyeri kepala (60,6%), proporsi status performa karnofsky terganggu sedang-berat (60,6%). Proporsi IMT estimasi normal sebanyak 34,8%, rerata IMT 23,46 ± 4,95 kg/m2, dengan mayoritas malnutrisi (54,5%) berdasarkan kriteria ASPEN.

Background: Central nervous system (CNS) tumors increase intracranial pressure and cause various neurological disorders that can affect the nutritional status of patients. Nutritional status influences both innate and adaptive immunity. In almost all malignancies, low levels of branched-chain amino acids (BCAA) are observed. Branched-chain amino acids enhance immunity by increasing neutrophil phagocytosis, lymphocyte proliferation, protein synthesis, and maintaining nutrient-sensitive signaling pathways. The neutrophil lymphocyte ratio (NLR) reflects the balance of the immune system with inflammation. An elevated NLR is associated with decreased body immune response, therapy outcomes, life expectancy, and prognosis. This study aims to determine the relationship between BCAA intake and NLR in CNS tumor patients.

Method: This is a cross-sectional study on CNS tumor patients treated at RSCM. Subject characteristics include age, gender, tumor type, neurological deficits, Karnofsky performance status, body mass index (BMI), nutrition status based on ASPEN, comorbidities, infection status, chemotherapy, radiation, and/or chemoradiation, glucocorticoid therapy, energy, and protein intake, BCAA intake, and NLR values. The analysis examines the relationship between two groups of BCAA intake divided according to the study population's median with NLR.

Results: There were 66 study subjects with a median age of 48 years, mostly female subjects (56,1%), with 38 subjects (57,6%) having secondary tumors. The highest neurological deficit was headache (60,6%), and the majority have a moderately to severely impaired Karnofsky performance status (60,6%). The proportion of estimated normal Body Mass Index (BMI) was 34.8%, with a mean BMI of 23,46 ± 4,95 kg/m2, and the majority were malnourished (54,5%) based on ASPEN criteria. Most subjects had no comorbidities (65,2%), no infections (80,3%), did not undergo chemotherapy, radiation, and/or chemoradiation (84,8%), and did not receive glucocorticoids (71.2%). The mean energy intake was 1519 kcal, protein intake 65 g/day, and the median BCAA was 9 g/day. There was a significant difference in the NLR values (p=0,047) between the group with BCAA intake <9 g/day (median NLR 4,9) and the group with BCAA intake ≥9 g/day (median NLR 3,1).

Conclusion: BCAA intake is related to NLR values in CNS tumor patients. Higher BCAA intake is associated with lower NLR values."

ABSTRACTThe decrease of muscle mass and strength in elderly people will affect thefunctional capacity and increase the risk of sarcopenia. One factor that can affect the loss of mass and muscle strength in elderly is the decrease in protein and branched chain amino acids (BCAA) intakes. This will affect the visceral protein status, especially prealbumin. The purpose of this study is to assess the association between intake of protein, BCAA and serum prealbumin level with muscle strength in elderly people. The methodology of this research is a cross-sectional study with 52 elderly people from April-May 2016. Food intake include energy, non-protein calorie (NPC), protein, and BCAA which is obtained from 2x24 hours food records. Blood sampling was performed after the subjects fasted for ± 8 hours, and muscle strength was measured with a Jamar's handgrip dynamometer. The results show there are no correlation between protein intake with the hand grip strength (r = 0,21 and p = 0,11), as well as AARC intake (r = 0,18 and p = 0,19) and prealbumin serum level (r = -0,056 and p = 0,69). This study concludes that low protein intake but accompanied with sufficient energy intake and BCAA will affect serum prealbumin level and muscle strength will be remained at normal values, however a statistically significant relationship is not found."

"Penelitian ini bertujuan untuk mengetahui asupan asam amino taurin dan korelasinya dengan aktivitas superoksida dismutase pada darah pasien osteoartritis lutut. Pada osteoartritis terjadi ketidakseimbangan antara prooksidan dengan antioksidan sehingga menimbulkan keadaan yang disebut stres oksidatif. Antioksidan enzimatik superoksida dismutase berperan dalam mencegah terjadinya stres oksidatif dengan cara memutus reaksi berantai radikal bebas sejak awal. Superoksida dismutase bekerja dengan cara mengkatalisis superoksida menjadi hidrogen peroksida. Pada osteoartritis diketahui terjadi peningkatan superoksida dan penurunan aktivitas superoksida dismutase. Asam amino taurin merupakan asam amino yang terdapat dalam jumlah tinggi di tubuh namun tidak ikut berperan serta dalam sintesis protein. Asam amino taurin banyak terdapat dalam bahan makanan sumber protein hewani terutama ikan, daging dan hasil laut. Asam amino taurin mempunyai beberapa sifat antara lain sebagai antioksidan, antiinflamasi, dan kondroprotektif. Penelitian ini menggunakan disain potong lintang dengan melibatkan 56 subjek OA lutut yang direkrut melalui consecutive sampling. Asupan taurin diambil dengan metode FFQ semikuantitatif.

The aim of this research was to observe the correlation between taurine amino acid intakes and superoxide dismutase activities on knee osteoarthritis patients. In osteoarthritis there is an imbalance state between pro oxidant and anti oxidant causing oxidative stress. The enzymatic anti oxidant superoxide dismutase plays an important role in stopping the occurrence of oxidative stress by cutting off the free radicals rsquo chain reaction from the beginning. Superoxide dismutase works by catalyzing superoxide into hydrogen peroxide. Osteoarthritis cases are known by the increase of superoxide and the decrease of superoxide dismutase activities. Taurine is an amino acid that is found abundant in human body that does not play a role in protein synthesis reaction. Taurine amino acid is found in several food sources including fish, meat, and seafood. Taurine amino acid has several characteristics including anti oxidant, anti inflammatory, and chondro protective. This study used cross sectional design with 56 knee osteoarthritis subjects recruited through consecutive sampling. Taurine intake was obtained by semiquantitative FFQ method. The superoxide dismutase activity sample was obtained from whole blood and measured using RANSOD SD 125 with spectrophotometric method. The statistical test used correlation test with SPSS. The mean age was 50.75 6.17 years old, with 89.3 of them were females. Median for taurine intakes was 59.77 15.96 ndash 278.57 mg per day.
