Abstract: Objective. This analysis focuses on the effect of depression on the cost of hospitalization of stroke patients. Methods. Data on 17,010 stroke patients (primary diagnosis) were extracted from 2008 Tennessee Hospital Discharge Data System. Three groups of patients were compared: (1) stroke only ( , ), (2) stroke + depression ( , ), and (3) stroke + other mental health diagnoses ( , ). Results. Of all adult patients, 4.3% were diagnosed with stroke. Stroke was more prevalent among blacks than whites (4.5% versus 4.2%, ) and among males than females (5.1% versus 3.7%, ). Nearly one-quarter of stroke patients (23.3%) were diagnosed with depression/anxiety. Hospital stroke cost was higher among depressed stroke patients ( ) compared to stroke only ( ) patients ($77,864 versus $47,790, ), and among , cost was higher for black males compared to white depressed males ($97,196 versus $88,115, ). Similar racial trends in cost emerged among females. Conclusion. Depression in stroke patients is associated with increased hospitalization costs. Higher stroke cost among blacks may reflect the impact of comorbidities and the delay in care of serious health conditions. Attention to early detection of depression in stroke patients might reduce inpatient healthcare costs. 1. Background Between 20% and 60% of stroke patients are diagnosed with depression/anxiety [1], and these are often newly diagnosed in stroke patients both during hospitalization and up to 3 years after discharge [1–20]. Depression is associated with longer institutionalization and poorer rehabilitation outcomes [21, 22]. Further, depression is more often diagnosed for females and white stroke patients [23, 24], and it is correlated with higher rates of suicidal ideation and stroke mortality [25–27]. Depression increases the risk of stroke [28] as well as increased healthcare costs [29–34]. As these and other stroke related factors are evaluated, understanding their impact on healthcare cost is necessary for better management, improved therapeutic outcomes, and reduced healthcare cost. 2. Depression and Healthcare Cost Several studies have reported the effect of depression/anxiety on healthcare costs. For example, while female Medicare patients had a higher prevalence of depression and higher use of outpatient services, inpatient hospital costs for male patients were 47% higher compared to females ($15,060 versus $10,240, ) [30]. In another study, the medical cost of depressed patients was 54% higher compared to nondepressed patients [34]. While higher cost among stroke patients is associated with
Perilaku Perambatan Retak pada Aluminium Paduan A2024-T351 dengan Menggunakan Spesimen CTS

Abstract: Fracture behavior of aluminum alloys under mixed mode (Mode I+II) loading was studied. Fracture tests were carried out on A2024-T351 aluminum. Compact-tension-shear specimen was employed and angle between loading axis and the crack surface was varied from 90°(mode I) to 0°(mode II). The crack extension (crack initiation and propagation) behaviors observed by a video microscope. Under a load with relatively high mode II components, the shear type crack initiation preceded the opening type crack propagation. Final fracture was occurred by shearing instability in the pure mode II loading. These experimental results were explained qualitatively by using finite element analysis. The critical values of stress intensity factors at crack initiation under mode II dominant conditions become smaller than those predicted by the maximum hoop stress criterion. It was also found that the rolling direction and small holes existing ahead of the crack-tip influence the crack extension behaviors. Abstract in Bahasa Indonesia : Penelitian ini membahas studi tentang perilaku retak aluminium paduan pada pembebanan mode campuran (mixed mode) (Mode I+II). Uji retakan dilakukan pada material aluminium paduan A2024-T351. Sudut antara arah pembebanan dan permukaan retakan dari spesimen Compact-tension-shear yang digunakan divariasikan dari 90°(mode I) sampai 0°(mode II). Perilaku dan arah perambatan retak diamati dengan video microscope. Pada pembebanan dengan komponen mode II relatif tinggi, maka inisiasi retakan jenis geseran terjadi lebih dahulu kemudian diikuti dengan jenis perambatan retak terbuka. Patah akhir terjadi karena ketidakstabilan geseran pada pembebanan mode II. Hasil eksperimental ini akan dijelaskan secara kualitatif dengan menggunakan analisa metode elemen hingga. Harga kritis dari faktor intensitas tegangan pada inisiasi retakan pada pemebebanan dimana mode II lebih dominan menjadi lebih kecil dari pada yang diprediksikan dengan kriteria tegangan hoop maksimum (maximum hoop stress criterion). Juga diperoleh bahwa arah pengerolan dan lubang-lubang kecil yang ada didepan ujung retak mempengaruhi perilku arah perambatan retak.

Abstract: Fracture behavior of aluminum alloys (A6061-T6) under mixed mode (Mode I+II) loading was studied. Compact-tension-shear (CTS) specimen was employed and angle between loading axis and the crack surface was varied from 90°(mode I) to 0°(mode II). The crack extension (crack initiation and propagation) behaviors observed by a digital microscope. Under a load with relatively high mode II components, the shear type crack initiation preceded the opening type crack propagation. Final fracture was occurred by shearing instability in the pure mode II loading. These experimental results were explained qualitatively by using finite element analysis Abstract in Bahasa Indonesia : Penelitian ini membahas perilaku retak material aluminium paduan (A6061-T6) pada pembebanan mode campuran (Mode I+II). Spesimen dibuat dalam bentuk Compact Tension Shear (CTS) dan menggunakan alat pembebanan dimana sudut antara sumbu pembebanan dan permukaan retak bervariasi dari 900 (mode I) sampai 00 (mode II). Perilaku retakan awal dan perambatan retak dimonitor dengan mikroskop digital. Semakin kecil sudut pembebanan, beban yang dibutuhkan pada spesimen untuk memulai terjadinya awal retakan semakin besar. Pada pembebanan dengan komponen mode II relatif tinggi, terlihat bahwa retak tipe geseran terjadi lebih dulu kemudian diikuti dengan retak tipe terbuka. Hasil-hasil eksperimen ini akan diklarifikasi dengan analisa numerik melalui simulasi metode elemen hingga.

UNTUK MENDETEKSI ANEMIA : APAKAH SAMA HASIL TEST HEMOGLOBIN DENGAN HASIL TEST HEMATOKRIT ?

Bulletin of Health Research , 2012,
Abstract: General medical and nutritional practice usually use hemoglobin value for the detection of anemia. Hematocrit test is rarely used, because the cutoff values for each segment of population still remain unclear. This study examined anemia prevalence rates using hemoglobin and hematocrit tests performed in underfive children, adult women and men. These data indicate that hemoglobin and hematocrit screening tests are highly correlated (r = 0.90) and are indeed comparable in detecting anemia in the same population. Using only hematocrit tests, the cutoff values for underfive children is 36 % or equal to 11 g/dl of hemoglobin, for adult women is 38 % or equal to 12 g/dl of hemoglobin, and for adult men is 42 % or equivalent to 13 g/dl of hemoglobin concentration. The hemoglobin and hematocrit tests are equally useful in detecting anemia, and that they can be used interchangeably for anemia screening.

Abstract: Penyelidikan ini dilakukan didaerah pegunungan di Jawa Timur pada masyarakat dengan penghasilannya rendah, untuk mengetahui sampai berapa jauh anemia terdapat pada ibu hamil maupun pada wanita dewasa normal. Ternyata 60 - 85 per cent dari seluruh wanita yang hamil maupun tidak hamil menderita nutritional anemia ringan maupun sedang. Sedangkan bagimereka yang mempunyai nilai haemoglobin rendah tidak harus selalu diikuti dengan rendahnya kadar protein serum, Packed Cell Volume, maupun serum iron. Hal ini mungkin dapat diterangkan karena adanya beberapa makanan yang dipantang sewaktu hamil dan juga oleh karena 80 percent dari total calori yang didapat adalah berasal dari beras dan 6-7 percent calori lainnya berasal dari ikan asin. Satu-satunya sumber protein mereka adalah juga dari ikan asin. Dari hasil penyelidikan Tjiat dan Soedarmo di Rumah Sakit Umum Jakarta didapat juga hasil bahwa 50 per cent dari ibu-ibu hamil menderita anemia ringan, 40.0 percent anemia sedang, dan 9.0 percent anemia berat yang kesemuanya itu disebabkan oleh karena nilai gizi makanan mereka yang kurang.

Abstract: The study on 1274 full term new born infants (gestational age > 37 weeks) in Bogor and its surroundings revealed the highly positive relationship between birth weight and birth length (R2 = 49.0%), birth weight and chest circumference (R2 = 53.3%), birth weight and head circumference (R2 = 40.6%). Regarding the anthropometric measurrements, the size of the infants were proportional. The head circumference appears to be useful as a predictor of low birth weight. Among the infants studied, 7.0% (N = 89) belongs to intra uterine growth retardation (IUGR) as a consequence of inadequate fetal growth. The relative risk of neonatal mortality of these IUGR infants was 7.4 times greater than those of the adequate birth weight infants (> 2500g).
