"Purpose: This multicenter, randomized controlled study evaluates the safety of early oral feeding following gastrectomy, and its effect on the length of postoperative hospital stay.Methods: The subjects of this study were patients who underwent distal gastrectomy (DG) or total gastrectomy (TG) for gastric cancer between January 2014 and December 2015. Patients were randomly assigned to the early oral feeding group (intervention group) or the conventional postoperative management group (control group) for each procedure. We evaluated the length of postoperative hospital stay and the incidence of postoperative complications in each group.Results: No significant differences in length of postoperative stay were found between the intervention and control groups of the patients who underwent DG. The incidence of postoperative complications was significantly greater in the DG intervention group. In contrast, the length of postoperative stay was significantly shorter in the TG intervention group, although the TG group did not attain the established target sample size.Conclusion: Early oral feeding did not shorten the postoperative hospital stay after DG. The higher incidence of postoperative complications precluded the unselected adoption of early oral feeding for DG patients. Further confirmative studies are required to definitively establish the potential benefits of early oral feeding for TG patients."

"Anak di bawah dua tahun berisiko tinggi untuk defisiensi zat gizi mikro khususnya defisiensi zat besi, sebagian dikarenakan praktek pemberian makanan tambahan yang salah. Untuk meningkatkan kualitas pemberian makanan tambahan, rekomendasi makanan tambahan (Complementary Feeding Recommendation - CFR) berbasis pangan lokal dibutuhkan. Suplementasi zat besi digunakan secara luas untuk menanggulangi defisiensi zat besi di negara berkembang; namun, efek dari suplementasi tersebut pada mikronutrien lain dan pertumbuhan menjadi perhatian tersendiri. Fortifikasi zat besi telah menunjukkan dampak negatif pada mikrobiota usus melalui peningkatan pertumbuhan bakteri patogen pada usus dikarenakan peningkatan besi yang diserap dan suplementasi zat besi mungkin memiliki dampak yang serupa pada mikrobiota usus tetapi masih belum pernah diteliti. Sebaliknya, jika suplementasi zat besi diberikan dengan optimalisasi diet menggunakan CFR, status gizi anak-anak akan meningkat dengan efek samping yang lebih kecil pada mikronutrien lain dan pertumbuhan. Studi ini meneliti efek dari suplementasi zat besi; dengan atau tanpa diet optimal; pada status mikronutrien, mikrobiota usus dan pertumbuhan anak-anak Myanmar yang berusia di bawah 2 tahun. Sebuah percobaan acak terkontrol (NCT01758159) dilaksanakan selama 24 minggu pada anak usia 12-23 bulan di Ayeyarwady, Myanmar. Optimalisasi CFR berbasis pangan lokal dikembangkan dengan pendekatan Linear Programming. Pengacakan berdasarkan Desa untuk CFR dan non-CFR dan berdasarkan anak (n=433) untuk suplemen besi atau placebo, menghasilkan: 1. kelompok CFR+Fe (n=112); 2. kelompok CFR (n=112); 3. kelompok Fe (n=105); or 4. kelompok pembanding (plasebo) (n=104). Ibu dari kelompok CFR menerima pendidikan CFR dan anak-anak dari kelompok Fe menerima 15 mg Ferric NaEDTA setiap hari. Serum Feritin, Transferin receptor (sTfR), Zinc, retinol-binding-protein (RBP), C-reactive protein dan α-1 acid glycoprotein; feces untuk melihat mikrobiota usus (Bifidobacteria, Lactobacilli, Enterobacteriaceae, E.coli, EPEC, EAEC dan ETEC) diukur pada awal dan akhir penelitian. Di awal penelitian, 88.4% anak mengalami anemia (Hb<110g/L); setelah dikontrol dengan infeksi, 74.4% mengalami defisiensi zat besi (SF<12μg/L dan/ atau sTfR>8.3mg/L) dan 68.9% mengalami anemia gizi besi (AGB) (Hb<110g/L and ID), 41.3% mempunyai kadar serum Send rendah (serum send <10.7µmol/L). Suplementasi besi menurunkan anemia, defisiensi zat besi dan AGB dengan atau tanpa pemberian diet optimal. Namun, suplementasi besi meningkatkan risiko serum Send rendah dan pendek (stunting) bila diberikan tanpa penambahan diet optimal. Efek samping ini tidak terlihat saat suplementasi tablet besi diberikan bersama dengan diet yang optimal. Tidak ada perbedaan yang nyata pada komposisi mikrobiota usus diantara semua kelompok. Suplementasi zat besi harus diberikan bersama dengan diet optimal untuk mengurangi efek samping baik pada kadar zat gizi mikro lainnya di dalam tubuh maupun pertumbuhan anak.

Children under 2-years of age are at high risk of micronutrient deficiencies especially iron deficiency (ID), partly due to poor complementary feeding practices. To improve feeding practices, local food-based complementary feeding recommendations (CFR) are needed. Iron supplementation is widely used to treat ID in developing countries; however, its potential effects on other micronutrients and growth are of concern. Iron fortification had shown negative impact on gut microbiota with increased growth of gut pathogens due to increased unabsorbed iron. It was assumed that iron supplementation may have similar impact on gut microbiota but has not yet been explored. On the other hand, if iron supplementation is given with optimized diet using CFRs, nutritional status of children would be improved with less adverse effects on other micronutrients status and growth.

The study investigated the effect of iron supplementation; given with or without optimized diet; on micronutrient status, gut microbiota and growth of under 2-year Myanmar children. A randomizedcontrolled trial (NCT01758159) was conducted for 24 weeks among 12-23 month old children from Ayeyarwady, Myanmar. Optimized CFRs based on locally available foods were developed by Linear Programming approach. Randomization by village for CFRs or non-CFRs and by child (n=433) for iron supplements or placebo, created: 1.CFR+Fe (n=112); 2.CFR-alone (n=112); 3.Fe-alone (n=105); or 4.Placebo (n=104) groups. Mothers from CFR-groups received education on CFRs and children from Fe groups received 15mg Ferric NaEDTA daily.

Serum for ferritin (SF), transferrinreceptor (sTfR), zinc, retinol-binding-protein (RBP), C-reactive protein and α-1 acid glycoprotein; stool for gut microbiota (Bifidobacteria, Lactobacilli, Enterobacteriaceae, E.coli, EPEC, EAEC and ETEC) were measured at baseline and endline. At baseline, 88.4% of children were anemic (Hb<110g/L); after adjusting for infection, 74.4% had ID (SF<12μg/L and/or sTfR>8.3mg/L) 68.9% had irondeficiency- anemia (IDA) (Hb<110g/L and ID), and 41.3% had low serum zinc status (serum zinc <10.7μmol/L).

Iron supplementation reduced anemia, ID and IDA whether or not it was given with optimized diet. However, iron supplementation increased the risk of low serum zinc and stunting when it is given without optimized diet. These adverse effects were not seen when iron supplementation was given with optimized diet. No significant difference was found in gut microbiota composition among groups. In conclusion, iron supplementation should be given together with optimized diet to reduce its adverse effect on other micronutrients status and growth to best improve nutritional status of these children."

"immune regulatory potency as it works on the macrophage and T cell to control inflammation and T cell dysregulation in elderly. None has been known about its effect on elderly with various states of frailty syndrome, which have different level of chronic low grade inflammation. This study aimed to determine the effect of alphacalcidol on inflammatory cytokines (IL-6, IL-10, g-IFN ) and T cell subsets (CD4/CD8 ratio and CD8+ CD28-) of elderly with various stages of frailty syndrome. Methods: from January to July 2017, a double blind randomized controlled trial (RCT) with allocation concealment, involving 110 elderly subjects from Geriatric Outpatient Clinic Cipto Mangunkusumo Hospital Jakarta, was conducted to measure the effect of 0.5 mcg alphacalcidol administration for 90 days to inflammatory cytokines (IL-6, IL-10, g-IFN) from PBMC culture supernatant, as well as CD4/CD8 and CD8+CD28- percentage using flow cytometry. Statistical analysis using SPSS version 20 was performed with t-test to measure mean difference. Results: of 110 subjects involved in the RCT consisting of 27 fit, 27 pre-frail and 56 frail elderly, 25(OH)D serum level was found to be as low as 25.59 (12.2) ng/ml in alphacalcidol group and 28.27 (10.4) ng/ml in placebo group. Alphacalcidol did not decrease IL-6 (p=0.4) and g- IFN (p=0.001), but it increased IL-10 (p=0,005) and decreased IL6/IL10 ratio (p=0.008). Alphacalcidol increased CD4/CD8 ratio from 2.68 (SD 2.45) to 3.2 (SD 2.9); p=0.001 and decreased CD8+ CD28- percentage from 5.1 (SD 3.96) to 2.5 (1.5); p<0.001. Sub group analysis showed similar patterns in all frailty states. Conclusion: Alphacalcidol improves immune senescence by acting as anti-inflammatory agent through increased IL-10 and decreased IL6/IL-10 ratio and also improves cellular immunity through increased CD4/CD8 ratio and decreased CD8+ CD28- subset in elderly. This effect is not influenced by frailty state.

Latar belakang: Alfakalsidol, suatu analog vitamin D, menunjukkan potensi regulasi imun saat bekerja pada makrofag dan sel T untuk mengontrol peradangan dan disregulasi sel T pada lansia. Saat ini belum diketahui efeknya pada orang tua dengan berbagai keadaan sindrom frailty yang memiliki peradangan kronis tingkat rendah yang berbeda. Penelitian ini bertujuan untuk mengetahui pengaruh alfakalsidol pada sitokin inflamasi (IL-6, IL-10, g-IFN) dan subset sel T (CD4/CD8 rasio dan CD8 + CD28-) lansia dengan berbagai status sindrom frailty. Metode: selama Januari hingga Juli 2017, uji coba terkontrol acak buta ganda (RCT) dengan penyembunyian alokasi, melibatkan 110 subjek lansia dari Poliklinik Geriatri RS Cipto Mangunkusumo Jakarta, dilakukan untuk mengukur efek pemberian alfakalsidol 0,5 mcg selama 90 hari terhadap inflamasi. Pengukuran sitokin (IL-6, IL-10, g-IFN) dari supernatan kultur PBMC, serta persentase CD4/CD8 dan CD8+ CD28- menggunakan flow cytometry dilakukan. Analisis statistik menggunakan SPSS versi 20 dilakukan dengan t-test untuk mengukur perbedaan rata-rata. Hasil: dari 110 subjek yang terlibat dalam RCT yang terdiri dari 27 orang sehat, 27 pra-lemah dan 56 orang lanjut usia lemah, 25 (OH) D serum adalah 25,59 (12,2) ng/ml dalam kelompok alfakalsidol dan 28,27 (10.4) ng / ml dalam kelompok plasebo. Alfakalsidol tidak menurunkan IL-6 (p=0,4) dan g-IFN (p=0,001), tetapi meningkatkan IL-10 (p=0,005) dan menurunkan rasio IL6/IL10 (p=0,008). Alfakalsidol meningkatkan rasio CD4/CD8 dari 2,68 (SD 2,45) menjadi 3,2 (SD 2,9); p=0,001 dan penurunan CD8+ CD28- persentase dari 5,1 (SD 3,96) menjadi 2,5 (1,5); p<0,001. Analisis sub kelompok menunjukkan pola yang sama di semua status frailty. Kesimpulan: alfakalsidol meningkatkan penuaan kekebalan dengan bertindak sebagai agen anti-inflamasi melalui peningkatan IL-10 dan penurunan rasio IL6/IL-10 dan juga meningkatkan imunitas seluler melalui peningkatan rasio CD4/CD8 dan penurunan CD8+ CD28-subset pada lansia. Efek ini tidak dipengaruhi oleh status frailty"

"Background: Nigella sativa (NS) seed extract shows diuretic activity, inhibits sympathetic nervous system overactivity and increases the production of Nitric Oxide in in vivo studies, thus it has a potential use as an adjuvant antihypertensive for elderly population. This study aimed to determine the effect of Nigella sativa seed extract to systolic blood pressure (SBP) and diastolic blood pressure (DBP) of elderly patients with hypertension. Methods: a double-blind, randomized controlled trial was conducted on elderly subjects with hypertension in three outpatient clinics in Cipto Mangunkusumo National Hospital Jakarta Indonesia from June to September 2011. Subjects were divided into intervention group given 300 mg Nigella sativa seed extract twice daily for 28 days and into another group which was given placebo. Blood pressure were measured on day 1 and 28. Intention o treat analysis using unpaired t-test to compare blood pressure after intervention between the two groups was performed. Results: of a total of 85 patients, 76 subjects fulfilled the study criteria and were randomized into 2 groups, with 38 subjects in each group. Both groups were comparable in all important prognostic factors. The mean systolic blood pressure of the NS group was decreased from 160.4 (SD 15.7) mmHg to 145.8 (SD 19.8) mmHg, and from 160.9 (16.3) mmHg to 147.53 (SD 22.0) mmHg in the placebo group (p=0.36). The mean diastolic blood pressure in the NS group was decreased from 78.3 (SD 11.9) to 74.4 (SD 8.2) mmHg, and from 79.0 (SD 12.4) to 78.2 (SD 8.9) in the placebo group (p=0.35). Reported adverse events include dyspepsia in 6 subjects (15.7%), nausea in 3 subjects (7.8%), and constipation in 2 subjects (5.2%). No electrolyte abnormalities, liver and renal toxicities, or orthostatic hypotension were observed. Conclusion: although a trend towards a slight decrease in blood pressure was observed, Nigella sativa has not been proven to be effective in reducing blood pressure in elderly patients with hypertension.

Latar belakang: ekstrak biji Nigella sativa (NS) pada penelitian in vivo menunjukkan potensi sebagai anti hipertensi karena memiliki efek diuretik, meningkatkan produksi Oksida Nitrit dan menghambat overaktivitas sistem saraf simpatis, sehingga potensial digunakan sebagai obat anti hipertensi pada pasien usia lanjut. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian ekstrak biji NS pada perubahan tekanan darah sistolik (TDS) dan tekanan darah diastolik (TDD) pasien usia lanjut dengan hipertensi.

Metode: dilakukan uji klinis acak tersamar ganda mulai Juni hingga September 2011 terhadap 76 pasien usia lanjut dengan hipertensi di tiga poliklinik di RS Cipto Mangunkusumo Jakarta Indonesia. Dengan alokasi tersamar, subyek dibagi menjadi kelompok yang mendapat kapsul berisi ekstrak biji NS 300 mg sebanyak 2 kali sehari selama 28 hari dan kelompok yang mendapat plasebo. Tekanan darah (TD) diukur pada hari ke-1 dan ke-28. Dilakukan analisis dengan uji-t tidak berpasangan untuk melihat perbedaan tekanan darah pada kedua kelompok setelah intervensi dengan prinsip analisis intention to treat. Hasil: dari 85 subjek yang memenuhi kriteria awal, didapatkan 76 subjek yang sesuai kriteria penelitian dan dirandomisasi menjadi dua kelompok, masing-masing terdiri dari 38 subjek. Pada akhir pengamatan, TDS kelompok NS turun dari 160,4 (SD 15,7) menjadi 145,8 (SD 19,8) mmHg and pada plasebo turun dari 160,9 (SD 16,3) menjadi 147,53 (SD 22,0) mmHg (p=0,36). TDD pada kelompok NS turun dari 78,3 (SD 11,9) menjadi 74,4 (SD 8,2) dan pada kelompok plasebo turun dari 79,0 (SD 12,4) menjadi 78,2 (SD 8,9) mmHg. Efek simpang yang dilaporkan adalah dispepsia pada 6 subjek (15,7%), mual pada 3 subjek (7,8%) dan konstipasi pada 2 subjek (5,2%). Tidak didapatkan gangguan elektrolit, gangguan fungsi ginjal, hati, maupun hipotensi ortostatik. Kesimpulan: meskipun menunjukkan kecenderungan penurunan tekanan darah, Nigella sativa belum terbukti dapat menurunkan tekanan darah pasien usia lanjut dengan hipertensi"

"Background: low-grade chronic inflammation in obese individuals contributes to the development of lipid abnormality and insulin resistance. Vitamin E has antioxidant and insulin-sensitizing properties, mediated by adiponectin. In this study, we aimed to evaluate the effect of vitamin E supplementation on lipid profiles and adiponectin levels in obese adolescents.Methods: this was a randomized, double-blind, controlled study. Obese adolescents aged 14-18 years, with no history of taking anti-obesity or antioxidant drugs, were recruited and randomized into two groups: vitamin E and placebo. The dose of vitamin E was 400 IU/day. Intervention was administered for two months. Lipid profiles and adiponectin levels were measured at baseline and after intervention. Primary outcomes were analyzed using the per-protocol analysis principle. Statistical analysis was performed using the independent t-test or the Mann-Whitney U test.Results: a total of 66 subjects completed the intervention study, 34 in the vitamin E group and 32 in the placebo group. Lipid profiles and adiponectin levels at 2 months after intervention did not differ significantly between the two groups. Changes from the baseline level were also not significantly different between the two groups and were inconsistent from one subject to another.Conclusion: in obese adolescents, vitamin E supplementation of 400 IU/day for 2 months does not significantly affect lipid profiles and adiponectin levels.

inflamasi kronik derajat rendah pada obesitas menyebabkan abnormalitas lipid dan resistensi insulin. Vitamin E mempunyai efek antioksidan dan dapat meningkatkan sensitivitas insulin dengan perantara adiponektin. Penelitian ini bertujuan untuk menilai efek suplementasi vitamin E terhadap profil lipid dan kadar adiponektin pada remaja dengan obesitas.

Metode: penelitian ini merupakan uji klinis acak tersamar ganda. Remaja obesitas berusia 14-18 tahun tanpa riwayat konsumsi obat-obatan antiobesitas atau antioksidan diikutsertakan dalam penelitian ini. Mereka dibagi menjadi dua kelompok menggunakan metode randomisasi: kelompok vitamin E dan plasebo. Dosis vitamin E yang digunakan adalah 400 IU/hari. Intervensi diberikan selama 2 bulan. Profil lipid dan kadar adiponektin diukur sebelum dan setelah pemberian intervensi. Hasil utama dianalisis menggunakan prinsip “per-protocol analysis”. Analisis statistik menggunakan uji t independen, dan uji Mann-Whitney U sebagai alternatifnya.

Hasil: sebanyak 66 subyek menyelesaikan penelitian, terdiri dari 34 subyek pada kelompok vitamin E dan 32 subyek pada kelompok plasebo. Profil lipid dan kadar adiponektin setelah intervensi selama 2 bulan tidak berbeda bermakna antara kedua kelompok. Perubahan parameter-parameter tersebut dari nilai dasar juga tidak berbeda bermakna antara kedua kelompok dan tidak konsisten dari satu subyek ke subyek lainnya.

Kesimpulan: pada remaja dengan obesitas, suplementasi vitamin E dengan dosis 400 IU selama 2 bulan tidak berpengaruh secara signifikan terhadap profil lipid dan kadar adiponektin."

"This study's aims were (a) to investigate the feasibility of a school-based motivational enhancement therapy (MET) intervention in voluntarily attracting adolescents who smoke marijuana regularly but who are not seeking formal treatment and (b) to evaluate the efficacy of the intervention in reducing marijuana use. Ninety-seven adolescents who had used marijuana at least 9 times in the past month were randomly assigned to either an immediate 2-session MET intervention or to a 3-month delay condition. Two thirds of the sample characterized themselves as in the precontemplation or contemplation stages of change regarding marijuana use. Participants' marijuana use and associated negative consequences were assessed at baseline and at a 3-month follow-up. Analyses revealed that both groups significantly reduced marijuana use at the 3-month follow-up ( p = .001); however, no between-group differences were observed. Despite the absence of a clear effect of MET, this study demonstrated that adolescents could be attracted to participate in a voluntary marijuana intervention that holds promise for reducing problematic levels of marijuana use."

"ABSTRACTThe aim of this study was to compare the immediate postoperative period of participants rehabilitated with dental implants placed with a conventional technique or with a minimally invasive technique, without a mucoperiosteal flap elevation (flapless). Participants who needed implant placement were divided into two groups: one group was operated using a mucoperiosteal flap elevation (GA), and the other with a flapless surgical technique (G B). Objective clinical parameters including oral hygiene, mouth opening, inflammation (facial perimeter), surgical time and analgesic consumption, as well as subjective parameters of pain and degree of satisfaction with the procedure, were evaluated. 48 implants were placed in 30 participants (15 participants per group). Oral hygiene index, maximum interincisal opening, pain and analgesic consumption values had a significant difference between groups favoring the flapless technique at 24 h and 7 days but at the 15 days follow-up the differences were only significant for oral hygiene and pain (P < 0.05); there were no statistically significant differences between groups in terms of facial perimeter values and surgical time (P > 0.05). Average on the degree of satisfaction was of 2.6 (SD 0.8) for G A and 3.6 (SD 1.02) for G B (P = 0.06). One implant placed in G A (2.0%) failed before prosthetic loading due to mobility and pain at 3 months follow-up. Participants operated for implant placement with flapless surgical technique go through less postoperative discomfort. Both techniques show high success rates, but to perform a flapless technique patients must be properly selected."
