The problem of flood inundation in the Kebon Agung River at the Medokan Ayu Village, Rungkut District Surabaya, is getting worse due to the conditions of topographic, soil properties, high rainfalls, rising sea tides and very significant changes in land use. The eastern part of Surabaya, which was formerly open space land and now developed into a residential area. Therefore in the area, there is often flood inundation when the rainy season due to lack of recharge areas and poor drainage facilities. The performance evaluation of the drainage system was carried out using the SWMM program that is combining hydrology and hydraulic analysis. Hydrology analysis is used to determine various rainfall return periods. The maximum rainfall data are collected for 18 years. The hydraulic analysis is used to obtain the data in the form of cross-section, roughness, and drainage channel capacity. The results of the evaluation of drainage system modeling with SWMM have obtained the inundation points, namely for channels K3-K4-K5- K6-K7-K8 on the right side and Ki2-Ki3-Ki4-Ki5 on the left side.
Pemasalahan genangan banjir di Kali Kebon Agung di Kelurahan Medokan Ayu Kecamatan Rungkut Surabaya menjadi semakin parah karena kondisi topografi, sifat tanah, tingginya intensitas hujan, meningkatnya pasang surut air laut dan perubahan tata guna lahan yang sangat signifikan. Wilayah Surabaya bagian timur yang semula lahan terbuka kini berkembang menjadi daerah perumahan. Oleh sebab itu di wilayah tersebut sering terjadi genangan banjir saat musim hujan dikarenakan kurangnya daerah resapan dan fasilitas drainase yang kurang baik. Evaluasi kinerja sistem drainase pada wilayah tersebut dilakukan dengan menggunakan pemodelan SWMM yang megabungkan pemodelan hidrologi dan hirdolika. Analisis hidrologi digunakan untuk menentukan berbagai kala ulang hujan. Data curah hujan maksimum digunakan selama 18 tahun. Analisis hidrolika digunakan untuk memperoleh data berupa penampang, kekasaran, dan kapasitas saluran drainase. Hasil running SWMM didapatkan titik titik lokasi genangan pada saluran K3-K4-K5-K6- K7-K8 pada sisi kanan dan Ki2-Ki3-Ki4-Ki5 pada sisi kiri.

<p>Biji melinjo kerikil mengandung resveratrol yang merupakan senyawa turunan stilbenoid dan mempunyai aktivitas antioksidan. Selama penyimpanan, senyawa resveratol dapat mengalami perubahan berupa oksidasi dan degradasi yang berdampak pada aktivitas antioksidannya. Penelitian ini bertujuan menduga umur simpan ekstrak kering beku biji melinjo kerikil berdasarkan kadar resveratrol dan aktivitas antioksidan (penghambatan radikal DPPH) sebagai indikator kerusakan. Pendugaan umur simapn dilakukan dengan metoda accelerated shelf life test (ASLT). Metoda ini didasarkan pada penyimpanan pada kondisi yang direkayasa sehingga mempercepat yang terjadinya kerusakan. Penyimpanan dilakukan selama 35 hari pada suhu simpan 35°C, 45°C adn 55°C. Hasil penelitian ini menunjukkan bahwa parameter mutu kritis pada penyimpanan ekstrak kering beku melinjo kerikil adalah aktivitas antioksidan (penghambatan radikal DPPH) karena memiliki energi aktivasi (1301,09 kal/mol) yang lebih rendah dibandingkan energi aktivasi kadar senyawa recveratrol. Umur simpan ekstrak keirng beku biji melinjo kerikil pada penyimpanan 35; 45; 55 dan 28°C berturut-turut adalah 13,57 hari, 12,67 hari, 11,83 hari dan 14,56 hari.</p><p> </p><p><strong>Shelf life estimation of melinjo kerikil seeds freeze-dried extract based on resveratrol and</strong><strong> </strong><strong>antioxidant activity</strong></p><p>Melinjo kerikil seeds contain resveratrol which is a stilbenoid derivative compound and has antioxidant activity.

Published: May 2020

Abstract
Background . Informal care provided by family caregivers to old persons is associated with a high risk of burden and poor health status. This study aimed to analyze the impact of Personalized Social Support (PSS) for non-dependent old persons living in the community on caregiver burden, satisfaction, and frailty. Methods . This non-interventional longitudinal study was performed in the southeast of France: old persons asking for PSS (>70 years of age, with no disability and no severe chronic disease, living at home) and their caregivers were included with a 6-month follow-up. Eligible dyads were visited at home by social workers. Caregiver burden was assessed with Mini-Zarit and frailty status with FiND (Frail Non-Disabled). Results . 876 dyads were eligible for PSS. Old persons were 82.2 ± 5.8 years old and 77.6% were women. Most caregivers were women (64.5%). Most caregivers were the children of the old person (61%), the rest were mostly spouses. Nearly 64% of old persons were frail and 38% were highly dependent. Follow-up was conducted for 686 dyads (78.3%). Of these, only 569 had PSS. The PSS was mainly for housework and meal preparation. At the time of follow-up, 53% of the caregivers for whom the old person had PSS had less difficulty helping their old person. Two-thirds (61.5%) of caregivers were fully satisfied with the PSS. Whether or not they had received the PSS, 73% of caregivers had reduced burden at 6 months, only 6% still had a high burden, 17% were less frail, and 18% felt healthier than at the time of inclusion. Conclusions . Our study highlights that non-dependent old person’s caregivers also experience burden. Implementing social support for activities of daily living had a major impact on their burden but not on their level of frailty. This means that the determinants of caregiver frailty are more complex and further studies are needed. Keywords: Caregiver’s burden. Old person. Personalized social support .

Abstract
Background： The purpose of this study was to evaluate the predictive value of the postoperative neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and lymphocyte-to-monocyte ratio (LMR) for early periprosthetic joint infection (PJI). Methods : During the period from January 2008 to December 2016, 104 patients (26 early PJI cases and 78 non-PJI cases) who underwent total joint arthroplasty at the Department of Orthopedics in our hospital were enrolled in this study. All of the relevant clinical information and laboratory indexes were reviewed from our hospital follow-up system. The time when any abnormal symptoms or signs occurred, including fever, local swelling or redness around the surgical site between the 2nd and 4th weeks after surgery, was defined as the “suspect time”. We compared laboratory parameters, including NLR, PLR, LMR, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), between the two groups. The trends of NLR, LMR, PLR, CRP and ESR were also reviewed after surgery. The predictive ability of these parameters at the suspect time for early PJI was evaluated by multivariate analysis and receiver operating characteristic (ROC) curve analysis. Results : NLR, PLR and LMR returned to preoperative levels within two weeks after surgery in the two groups. In the early PJI group, NLR and PLR were significantly increased during the incubation period of infection or infection, and LMR was significantly reduced, although 61.5% (16/26) of the patients had normal white blood cells. Interestingly, ESR and CRP were still relatively high two weeks after surgery, and the change in these two indexes was not obvious when infection occurred. NLR and PLR were significantly correlated with early PJI (Odds ratio (OR) N LR =88.36, OR PLR =1.12, P NLR =0.005, P PLR =0.01), and NLR had great predictive ability for early PJI, with a cut-off value of 2.77 (sensitivity=84.6%, specificity=89.7%, 95% CI=0.86-0.97) . Conclusions: ESR and CRP are not sensitive for the diagnosis of early PJI due to their persistently high levels after arthroplasty. The postoperative NLR at the suspected time has a great ability to predict early PJI, and more attention should be paid to it.

Abstract
Background: First permanent molars (FPMs) are the most critical teeth in the dental arc. Meanwhile they bear the highest risk for carious lesions. The aim of this study was to investigate the caries status of primary and permanent teeth among 8-9-year-old children in Guangzhou, and the correlation between the caries of primary molars and first permanent molars (FPMs).Methods: 119 samples of children aged 8-9 were included. The scoring and evaluation were processed in accordance with International Caries Detection and Assessment System (ICDAS). Statistical analysis was performed using SPSS 20.0 software package by means of Pearson Chi-square test and Kendall’s correlation.Results: Pearson Chi-Square test showed that the prevalence of dental caries of the first primary molars, second primary molars and primary molars had significant correlation with that of FPMs, while Kendall’s correlation analysis showed that they had weak positive correlation. What’s more, the Pearson chi-square test showed that there was no significant correlation between the degree of dental caries of different primary molars and FPMs.Conclusion: Caries in primary molars, especially the second molars, were considered to be a risk indicator for the development of permanent molars in the future. However, regardless of the degree of primary molars caries, the susceptibility of FPMs caries should be aware of. And pit and fissure sealants for them should be carried out as soon as possible.

Abstract
Background High body mass index (BMI) is a risk factor for type 2 diabetes and cardiovascular disease. However, its relationships with indices of carotid stiffness and plaque volume are unclear. We investigated associations of long-term measurements of BMI with indices of carotid stiffness and atherosclerosis among non-demented diabetes patients from the Israel Diabetes and Cognitive Decline (IDCD) study.Methods Carotid ultrasound indices [carotid intima media thickness (cIMT), distensibility, elastography and plaque volume] were assessed in N = 471 participants. Mean BMI across all MHS diabetes registry measurements and trajectories of BMI were calculated. BMI was categorized into three trajectory groups representing: a relatively stable normal weight (n = 185, 44%), overweight trajectory (n = 188, 44.8%) and a trajectory of obesity (n = 47, 11.2%). Linear and logistic regressions estimated associations of carotid indices with mean BMI and BMI trajectories.Results Compared to the normal weight trajectory, an obesity trajectory was associated with carotid distensibility (β=-3.078, p = 0.037), cIMT (β = 0.095, p = 0.004), and carotid elastography (β = 0.181, p = 0.004) but not with plaque volume (β = 0.066, p = 0.858). Compared with the normal weight trajectory, an obesity trajectory was associated with increased odds for impaired carotid distensibility (OR = 2.790, p = 0.033), impaired cIMT (OR = 5.277, p = 0.001) and large carotid plaque volume (OR = 8.456, p = 0.013) but not with carotid elastography (OR = 1.956, p = 0.140). Mean BMI was linearly associated with Distensibility (β=-0.275, p = 0.005) and cIMT (β = 0.005, p = 0.026).Conclusions Long-term measurements of adiposity are associated with indices of carotid stiffness and plaque volume among older type 2 diabetes adults.

Abstract
Background: The efficacy of paclitaxel-eluting balloon catheters (PEB) is affected by the method of binding paclitaxel to the balloon catheter surface. The aim of this study was to compare the long-term efﬁcacy of seal-wing and iopromide-coated PEB for bare-metal stent restenosis (BMS-ISR) treatment. Methods:We analyzed 3-year clinical follow-up data of 132 patients with BMS-ISR. 64 of them were treated with seal-wing PEB, the control group comprised 68 patients from the iopromide-coated PEB arm of the previous TIS clinical study. Primary end-points included the occurrence of major adverse cardiac events (MACE; cardiovascular [CV] death, myocardial infarction [MI], or target vessel revascularization [TVR]) Results:At 3 year clinical follow-up, the incidence of MACE was significantly higher in the seal-wing PEB than in the iopromide-coated PEB group (40.6 % vs. 19.1%; p=0.008); the same can be said about TVR (26.9% vs. 8.8%; p=0.011). Similarly, the event-free survival was significantly longer in the iopromide-coated PEB than in the seal-wing PEB group (p=0.021). No significant differences were found between the groups where CV mortality (4.7% vs. 5.9%; p=1.000), MI (6.3% vs. 4.4%; p=0.712), definite stent thrombosis (0% vs. 2.9%; p=0.497) or the second MACE (4.7% vs. 1.5%; p=0.354) are concerned.Conclusions: Compared to iopromide-coated PEB, the use of seal-wing PEB for BMS-ISR treatment led to a significantly higher 3-year occurrence of MACE and TVR.
