The clinical factors' prediction of increased intradialytic QT dispersion on the electrocardiograms of chronic hemodialysis patients.

Ventricular arrhythmias and sudden death are common in patients on maintenance hemodialysis (HD). The increase in QT dispersion (QTd) on the electrocardiogram (ECG) reflects increased tendency for ventricular repolarization that predisposes to arrhythmias. The purpose of the study was to identify the clinical factors that may predict the increased intradialytic QTd and to assess differences in QTd before and after HD. Each of 61 chronic HD patients underwent 12-lead ECG and blood pressure (BP) measurement before and every 1 h during a single HD session. The QT intervals were corrected for heart rate using Bazetts formula. Intradialytic QTd increased in 30 (49%) patients. There was no correlation between the increased QTd and the clinical factors including hypertension, pulse pressure, intradialytic hypotension, left ventricular hypertrophy, old myocardial infarct, diabetes mellitus, and nutritional status. The means of QT interval and QTd increased after HD session (from 382 ± 29 to 444 ± 26 ms, P <0.05; and from 74 ± 21 to 114 ± 53 ms, respectively, P <0.05). We conclude that the increased intradialytic QTd could not be predicted by any of the clinical factors evaluated in this study. There was significant difference in the means of QTd before and after HD session.

Proportion and Factors Associated with Zinc Deficiency in Acute Diarrhea Patients

Background: Zinc may affect the intestinal immune response. No data has been available on zinc deficiency in adult patients with diarrhea, especially for Indonesian population. Zinc metabolism, etiologies, pathogenesis and clinical course of diarrhea may have various effects on zinc concentration in different population. This study aimed to determine the proportion of zinc deficiency in patients with acute diarrhea, including its associated factors. Method: A cross-sectional study was conducted in patients with acute diarrhea at outpatient clinics and emergency wards of four hospitals between August 2010 and March 2011. A serum zinc concentration of < 10.7 µmol/L was set as cut-off value for zinc deficiency. Data was analyzed by using Chi-square test. Results: There were 101 subjects, 54.5% were female, the median age was 26 years, median duration of acute diarrhea was 5 days, and the median frequency was 6 times/day. About 95% patients had nutritional status of subjective global assessment (SGA) A and the mean value of body mass index was 19.3 ± 0.70 kg/m2. Approximately 88.1% patients had severe infective diarrhea based on hydration status. About 69.3% patients were zinc deficient with the mean serum zinc concentration of 9.26 ± 2.95 µ mol/L. We found a significant correlation between the severity of diarrhea and zinc deficiency in patients with acute diarrhea. Conclusion: The proportion of zinc deficiency in acute diarrhea patients was quite large although the mean serum zinc level was still below the National Health and Nutrition Examination Survey (NHANES) reference value. The severity of diarrhea has been proven to be significant that affects zinc deficiency in acute diarrhea patients. Keywords: zinc deficiency, acute diarrhea, adult

The role of autosuggestion in geriatric patients' quality of life: a study on psycho-neuro-endocrine-immunology pathway.

ABSTRACT Background: There has been no study conducted about the effect of autosuggestion on quality of life for geriatric patients. Our aim was to evaluate the efficacy of autosuggestion for geriatric patients’ quality of life and its impact on psycho-neuro-endocrine-immune pathway. Methods: Sixty geriatric patients aged ≥60 years in a ward were randomly assigned to either receive autosuggestion or not. Autosuggestion was recorded in a tape to be heard daily for 30 days. Both groups received the standard medical therapy. Primary outcome was quality of life by COOP chart. Secondary outcomes were serum cortisol level, interleukin-2, interleukin-6, interferon-γ, and N-acetylaspartate/creatine ratio in limbic/paralimbic system by magnetic resonance spectroscopy. The study was single blinded due to the nature of the intervention studied. Results: Out of 60 subjects, 51 finished the study. The autosuggestion group reported better scores than the control one for quality of life, COOP chart 1.95 vs. 2.22 (95% CI, p = 0.02). There were increments of serum cortisol (p = 0.03) and interleukin-6 in the autosuggestion group (p = 0.04). Interleukin-2, interferon-γ, and N-acetylaspartate/creatine ratio in prefrontal cortex showed a tendency to increase in the autosuggestion groups. Conclusion: Autosuggestion is associated with improvement of geriatrics’ quality of life, serum cortisol level, and adaptive immunity. There is a better trend for neuroplasticity in prefrontal cortex in the autosuggestion group.

Serokonversi Hepatitis C pada Pasien Hemodialisis di Rumah Sakit Cipto Mangunkusumo

Pendahuluan. Pasien hemodialisis (HD) tergolong kelompok risiko tinggi terinfeksi virus hepatitis C. Penelitian mengenai serokonversi hepatitis C di RS Cipto Mangunkusumo belum pernah dilakukan. Agar transmisi hepatitis C dapat diturunkan, faktor risiko serokonversi hepatitis C penting diketahui. Penelitian ini bertujuan mengetahui proporsi dan faktor risiko serokonversi hepatitis C pada pasien yang menjalani HD di RS Cipto Mangunkusumo. Metode. Penelitian potong lintang terhadap pasien yang menjalani HD di RS Cipto Mangunkusumo pada bulan Juni-Juli 2011. Pemeriksaan anti-HCV menggunakan Roche Elecsys ECLIA, Analisis multivariat menggunakan regresi logistik. Hasil. Pada bulan Juni-Juli 2011 terdapat 135 pasien HD yang memenuhi kriteria inklusi dan eksklusi. Serokonversi mencapai 21,5%. Analisis bivariat menunjukkan hubungan yang bermakna antara lama dialisis (p=0,003) dan jenis kelamin pria (OR 2,43; 95%CI 0,99-5,98; p=0,048) dengan serokonversi hepatitis C. Pasien yang menjalani dialisis >42 bulan (sebelum pemrosesan ulang dialiser menggunakan mesin) lebih banyak yang mengalami serokonversi dibandingkan pasien yang mengalami dialysis ≤42 bulan. Terdapat dua variabel yang marginally statistically significant yaitu HBsAg negatif (p=0,07) dan menggunakan dialiser proses ulang (p=0,07). Pada analisis multivariat, didapatkan jenis kelamin pria (OR 2,91; 95%CI 1,14-7,48; p=0,03) dan lama dialisis (OR 1,02; 95%CI 1-1,03; p=0,007) berhubungan dengan serokonversi hepatitis C. Simpulan. Serokonversi hepatitis C pada pasien yang menjalani HD di RS Cipto Mangunkusumo mencapai 21,5%. Terdapat hubungan signifikan antara jenis kelamin pria dan lama dialisis dengan serokonversi hepatitis C.

Determinan Diagnostik Klinis Defisiensi Vitamin D pada Wanita Berusia Lebih dari 50 Tahun

Pendahuluan. Prevalensi deifisiensi vitamin D pada wanita 50 tahun ke atas di Indonesia cukup tinggi namun pemeriksaan kadar vitamin D serum sangat mahal. Oleh karena itu, diperlukan alat penyaring defisiensi vitamin D yang cukup ekonomis dan sederhana untuk dikerjakan di layanan kesehatan primer. Metode. Penelitian ini merupakan penelitian diagnostik, menggunakan desain potong lintang ( cross-sectional ) sehubungan dengan pengambilan data hanya dilakukan sewaktu saja. Penelitian ini dilakukan di Kotamadia Bandung selama Agustus–Oktober 2012. Pada 240 subjek, dilakukan pengumpulan data berupa karakteristik responden, diabetes mellitus, penyakit ginjal kronik, riwayat jatuh, riwayat fraktur setelah menopause, nyeri tulang, skor paparan sinar matahari, skor proteksi sinar matahari, status gizi, kinerja fisik ( 5 timed chair-stands dan uji sikap tandem), status kesehatan (jumlah dan derajat berat penyakit kronis), kadar vitamin D serum. Untuk pengujian statistik hubungan antara dua variabel kualitatif dikotom dilakukan dengan uji Chi-square dilanjutkan dengan uji multivariat. Hasil. Penelitian ini menemukan hubungan yang bermakna secara statistik antara diabetes mellitus, skor proteksi matahari, kelemaan otot ekstremitas bawah dengan defiisensi vitamin D. Berdasarkan ketiga determinan tersebut, dapat dibuat sistem skoring yang dapat digunakan untuk menyaring kelompok wanita 50 tahun ke atas yang mempunyai probabilitas besar menderita defisiensi vitamin D. Simpulan. Determinan diagnostik defisiensi vitamin D berat yang ditemukan pada penelitian ini meliputi: adanya diabetes melitus, skor proteksi matahari, kelemahan otot tungkai bawah. Sistem skoring untuk menyaring defisiensi vitamin D berat pada wanita berusia 50 tahun ke atas dapat dibuat berdasarkan ketiga determinan tersebut di atas. Bobot untuk masing-masing determinan adalah: 1 untuk diabetes mellitus dan kelemahan otot tungkai bawah serta 2 untuk skor proteksi matahari. Bila penjumlahan dari skor ketiga komponen tersebut ³2, maka subjek tersebut diprediksi menderita defisiensi vitamin D berat.
