Pendahuluan: Pada traumatic brain injury (TBI) dapat terjadi peningkatan metabolisme sehingga pasien rentan mengalami malnutrisi. Tatalaksana nutrisi yang adekuat sesuai dengan kondisi klinis dan komorbiditas berperan dalam mencegah terjadinya malnutrisi, menurunkan morbiditas dan mortalitas, serta mengoptimalkan outcome neurologis. Presentasi Kasus: Keempat pasien dalam serial kasus ini adalah laki-laki berusia antara 31?60 tahun dengan TBI dan berbagai faktor penyulit. Pasien pertama dengan obesitas dan mengalami hiponatremia berulang selama perawatan, pasien kedua memiliki status gizi malnutrisi, pasien ketiga dengan riwayat kemoradiasi pada astrositoma, amiloid angiopati dan disfagia, sementara pasien keempat dengan hipertensi dan fibrilasi atrium. Skrining gizi dengan MST pada keempat pasien menunjukkan skor dua. Pemberian energi pada keempat pasien adalah sebesar 140?150% dari kebutuhan energi basal yang dihitung dengan Harris-Benedict, dengan target pemberian protein sebesar 1,5?1,9 g/kg BB/hari atau setara dengan 20% energi. Selama pemantauan asupan protein pada keempat pasien adalah sebesar 0,55?1,67 g/kg BB/hari atau setara dengan 13,1?19,5% energi. Restriksi cairan dilakukan pada pasien pertama sebagai tatalaksana hiponatremia yang diperkirakan terjadi akibat SIADH. Pemberian natrium pada pasien keempat tidak direstriksi meskipun pasien mengalami hipertensi karena hipertensi adalah salah satu mekanisme kompensasi pada TBI. Pasien ketiga mengalami disfagia jika mengasup air putih sehingga dilakukan latihan menelan. Asupan per oral dimulai pada hari ke 6?15 pasca trauma. Hasil: Keempat pasien menunjukkan perbaikan outcome neurologis yang tampak berdasarkan peningkatan skor GCS disertai peningkatan kapasitas fungsional. Kesimpulan: Tatalaksana nutrisi yang adekuat pada pasien TBI dengan mempertimbangkan komorbiditas pasien diperlukan untuk menunjang penyembuhan dan memperbaiki outcome pasien.

ABSTRACT Chronic kidney disease is a irreversible progressive chronic process that causes worsening renal function. Patients with end stage renal disease needs renal replacement therapy to protect themselves from uremia toxicity. Patients who have to undergo dialysis are in high catabolism state and has an increased energy and protein expenditure. Adequate energy and protein for these patients are needed to prevent protein energy wasting PEW . Four cases from this serial case has ESRD and has been on hemodialysis with different time frames. Two outpatient and two inward patients who have CKD stage V with hypertension, diabetes mellitus, and uremic encephalopathy. Although only one patient I categorized as mildly malnourished, 3 of four patients experienced weigth loss 10 in 6 months. Thus, medical nutritional therapy is needed to determine energy and protein requirements in these patients. Evaluation and monitoring form these cases shows that all patients have better clinical outcome, better nutrition intake, and functional capacity were preserved. Medical nutrition therapy has an important role in all CKD patients with dialysis to prevent PEW, to improve their clinical outcome and to increasetheir functional capacity. Key words medical nutrition therapy, chronic kidney disease, hemodialysis, hipertension.

ABSTRACT Background: The prevalence of heart failure increase annually, 60-70% due to coronary heart disease (CHD). Some of the risk factors associated with heart failure are diabetes, hypertension, obesity, metabolic syndrome, and atherosclerosis. The phatophysiology of heart failure is very complex and involves many systems. The occurance of hypermetabolism can lead to weight loss and triger malnutrition. The state of acute decompensated heart failure due to old myocardial infarction require immediate treatment in hospital to avoid further complications. Methods: This series of case report describes four cases of patients with acute myocardial heart failure, due to old infarction, aged between 41 to 70 years old, and three of them with a history of type 2 diabetes melitus. All patients required nutritional support, three patients had nutritional status of obese and one patient was normal in weight. The problems which closely linked to all nutrition of the four patients were hypoalbuminemia, electrolyte disturbances, impaired renal function, impaired liver function, fluid inbalance, and micronutrient deficiencies. Basal Energy Requirement was calculated using Harris Benedict formula with stress factors corresponding clinical condition and comorbidities. Macronutrients composition was given according to the recommendation of the Therapeutic Lifestyle Changes (TLC) and the American Heart Association (AHA), while the provision of proteins was tailored with the kidney function of each patient. Micronutrients supplementation was also given to four patients. Patient monitoring parameters included subjective complaints, hemodynamic, analysis tolerance of intake, laboratory tests, anthropometric, fluid balance and functional capacity. Results: During the monitoring period in the hospital four patients showed clinical improvement, increased tolerance of intake, improved electrolyte levels and increased functional capacity. Conclusion:Adequate medical nutrition therapy can improve the clinical condition of patients with acute decompensated heart failure due to old myocardial infarction.
