"Penyakit Paru Obstruktif Kronik PPOK adalah penyakit akibat stres oksidatif penyebab menurunnya fungsi paru sehingga mempengaruhi kualitas hidup penderitanya.Tes baku untuk mengukur kualitas hidup PPOK adalah COPD AssessmentTest CAT . Vitamin C sebagai antioksidan banyak terdapat di cairan pelapis epitel paru. Penelitian ini bertujuan mengetahui korelasi antara kadar vitamin C serum dan skor CAT pada PPOK. Penelitian potong lintang ini dilakukan di RSUP Persahabatan,Jakarta Timur, melibatkan 47 subjek dengan metode consecutive sampling. Data karakteristik subjek dan asupan vitamin C secara FFQ semikuantitatif didapatkan melalui wawancara. Data klasifikasi klinis, fungsi paru, komorbid, skor CAT didapatkan dari rekam medis dan wawancara. Status gizi ditentukan berdasarkan Indeks Masa Tubuh IMT , dan kadar vitamin C serum dengan spektrofotometer. Semua subjek laki-laki, rerata usia 66,6 tahun, sebagian besar bekas perokok berat dengan fungsi paru rendah. Status gizi kurang pada 25 subjek, skor CAT kategori ringan, asupan vitamin C cukup, dan kadar vitamin C rendah. Tidak didapatkan korelasi antara kadar vitamin C serum dan skor CAT.

COPD is a disease due to oxidative stress causing low pulmonary function, resulting in low quality of life. A standard test to measure the quality of life in COPD is COPD Assessment Test CAT . Vitamin C as antioxidant is widely available in the pulmonary epithelial fluid. This study aimed to investigate the correlation between serum vitamin C level and CAT score in COPD. This cross sectional study was conducted at Persahabatan Hospital, East Jakarta, involving 47 subjects using consecutive sampling method. Interview was used to assess subjects rsquo characteristics and vitamin C intake using semi quantitative FFQ. Clinical classification, lung function, comorbidity, and CAT scores were gathered from medical records or interview. BMI was used to determine nutritional status, while vitamin C serum level was assessed using spectrophotometry. All subjects were male, mean age was 66.6 years, mostly ex heavy smokers, with decreased lung function, and 25 were undernourished. Vitamin C intake was sufficient, but low in serum vitamin C level and CAT score. There was no correlation between serum vitamin C levels and CAT score. "

"Malnutrisi pada kanker nasofaring (KNF) disebabkan oleh peradangan, sel tumor dan efek kemoradioterapi. Malnutrisi dikaitkan dengan penurunan kualitas hidup, fungsi fisik, dan kelangsungan hidup. Pemberian nutrisi pasien KNF yang menjalani radioterapi (RT) memperbaiki status gizi, kapasitas fungsional, dan prognosis keseluruhan. Pasien KNF dengan kaheksia, usia 29 - 67 tahun, tiga pria dan satu wanita yang menjalani kemoradioterapi. Diberikan nutrisi sesuai kebutuhan energi, makronutrien, mikronutrien, dan nutrien spesifik. Pemantauan pasien di awal, hingga RT selesai, pada keluhan terkait terapi, analisis asupan, antropometri, komposisi tubuh, kapasitas fungsional, dan pemeriksaan CRP. Didapatkan penurunan asupan pada empat pasien saat RT, tetapi meningkat lagi pada tiga pasien setelah pemasangan NGT. Satu pasien dengan peningkatan berat badan (BB), sedangkan 3 pasien lainnya BB menurun 2,2-13% pasca RT. Tiga pasien dengan CRP meningkat pada awal RT, tetapi hanya 1 pasien dengan CRP kembali normal. Massa otot meningkat pada 3 pasien setelah RT. Tiga pasien mengalami perbaikan skor ECOG pasca RT, dan satu pasien dengan skor ECOG tetap stabil. Pemasangan NGT dapat mempertahankan asupan pasien. Terapi nutrisi memperbaiki penurunan BB, tetapi tidak terlihat kaitan dengan CRP, massa otot dan kapasitas fungsional karena faktor lain.

Malnutrition in nasopharyngeal carcinoma (NPC) is induced by inflammation, tumor cells and the effects of chemoradiotherapy. Malnutrition is associated with decrease in quality of life, physical function and survival. Nutritional therapy to NPC who underwent radiotherapy (RT) improves nutritional status, functional capacity, and prognosis. NPC cachexic patients, ages 29 - 67 years, three male and one female, all underwent chemoradiotherapy. Nutrition therapy start with planning of energy, macronutrient, micronutrient and specific nutrients needs. Patients monitoring start from the the beginning, until completed RT, related to therapy, intake analysis, anthropometry, body composition, functional capacity, and C-Reactive Protein (CRP) examination. Decrease intake in four patients during RT, but it increased in three patients after NGT insertion. One patient increase body weight (BW), while other 3 patients dropped BW 2.2-13% post-RT. Three patients increase in CRP at the start of RT, but only 1 CRP patient returned to normal. Muscle mass increased in 3 patients after RT. Three patients had improved ECOG scores after RT, and one patient with ECOG scores remained stable. Insertion of NGT can maintain patient intake. Nutritional therapy maintains BW, but does not appear to be related to CRP, muscle mass and functional capacity due to other factors."
