KETAKSAMAAN HERMITE-HADAMARD TERHADAP INTEGRAL RIEMANN-STIELTJES
Authors: Hakim Denny Ivanal , Gunawan Hendra 
Published: September 2020

The Hermite-Hadamard inequality is an inequality for convex functions that gives an estimate for the integral mean value of a convex function on a closed interval by its value at the middle of interval and the average of its values at the endpoints. The Hermite-Hadamard inequality can be generalized by using the Riemann-Stieltjes integral mean value. An application of the Hermite-Hadamard inequality with respect to Riemann-Stieltjes integral for estimating the power mean of positive real numbers by the aritmethic mean is given at the end of discussion.

This paper presents the modeling of the amount of sugar and molasses production in Pabrik Gula Candi Baru Sidoarjo (PGCBS), East Java, by using multivariate mixedlinear models. Estimation of parameters will be done by using maximum likelihood coupled with restricted maximum likelihood methods. The amount of sugar and molasses products which have strong linear correlation, will be set as responses and are supposed to be affected by seven fixed effect variables and four random effect variables. This paper demonstrates that the seven fixed effect variables and only one random effect variable have significant influence on a single response. In the multivariate response modeling, however, all of variables fail to explain the variability of these two responses simultaneously. It is due to the factors matrix has no full rank. As a result, the model response of molasses can be explained by using a model of the amount of sugar obtained.

Poverty is one of the problems that becomes concern in all countries. In Indonesia, one of the provinces that has high poverty rates is Jambi (9.12% in 2015).Result of coordination meeting of all Camat in Jambi Province, reported that the Tabir Barat is the poorest sub-district. The condition is caused mostly by inadequate household infrastructure. Therefore it is necessary for grouping households based on the household infrastructure condition to find the household groups which should be prioritized in the development of poverty alleviation. To describe the poverty variable based on household infrastructure, Bappeda uses 9 indicators, that are residential building status, the widest type of floor, the widest type of wall, the widest type of roof, drinking water source, defecation facility, stool drainage, main lighting and cooking fuel. Because of the folowing reasons: the poverty is an unmeasurable latent variable, and indicators of poverty are categorial variables, the Latent Class Cluster analysis were used in this research as a grouping method. The result shows that there are 5 clusters / latent classeswith their respective characteristics of the household in the Tabir Barat.

Published: September 2020

This cross-sectional study aimed to assess HIV-related knowledge and attitudes of PHMs, the frontline community health workers in Sri Lanka. Two-hundred and ninety-one PHMs were recruited. PHMs’ knowledge level was good (79.9% of answers were correct) but could be improved. Those more knowledgeable about HIV and with higher education demonstrated a more positive attitude toward PLWH. A more negative attitude, less training and older age were associated with having a stronger intention to engage in extra precautionary behaviors. PHMs need further HIV training to improve their knowledge to better educate the community. By reducing PHMs misperceptions about HIV, they may develop a more positive attitude and thus help reduce the general public’s stigma associated with PLWH.

Children’s physical activity level and sedentary behavior in Norwegian early childhood education and care: effects of a staff-led cluster-randomized controlled trial
Authors: Andersen Eivind , Øvreås Steinar , Jørgensen Kari Anne , Borch-Jenssen Janne , Moser Thomas 
Published: September 2020

Abstract
Background: A growing body of evidence suggests that children’s physical activity (PA) level in early childhood education and care (ECEC) settings is insufficient. Since most children attend ECEC settings for many hours on most days of the week and these institutions reach children across the socioeconomic spectrum, ECEC settings may serve as an ideal avenue for increasing PA level, reducing sedentary time and enhancing the overall health of young children. This paper investigates the effectiveness of the “Active Kindergarten – Active Children” study in increasing children’s PA level and reducing sedentary time within the ECEC setting. Methods: Accelerometers were used to assess PA and sedentary time. A total of 116 three- to four-year-olds took part in a randomized controlled trial in 11 ECEC settings. The participants were cluster-randomized, by ECEC setting, to either a 12-week staff-led and expert-supported intervention or a waiting-list control group. Results: The intervention group increased time spent in moderate- and vigorous-intensity PA by 10 min/day (95% CI = 3, 18; P=0.01), took 1909 more steps per day (95% CI = 1130, 2688; P˂0.01) and reduced sedentary time by 14 min/day (95% CI = -27, -1; P=0.04) compared to the control group. The intervention group was 2.4 times more likely (95% CI = 1.05, 5.7; P = 0.04) to meet the PA recommendations than the control group at follow-up. Conclusions: Our results show that a flexible staff-led and expert-supported multi-component PA intervention can increase the total PA level and moderate- and vigorous-intensity PA and reduce sedentary time in three- to four-year-old children during their stay in ECEC settings.

Published: September 2020

Abstract
Background: Magnesium sulfate (MgSO4) is the standard drug for eclampsia prophylaxis and treatment. In China, the effective therapeutic serum magnesium level is 1.8–3.0 mmol/L. There is little information on how to achieve and maintain effective therapeutic concentrations. This study aimed to investigate risk factors for sub-therapeutic serum concentrations of MgSO4 in patients with severe preeclampsia. Methods: Patients with severe preeclampsia who received MgSO4 intravenous infusion were retrospectively reviewed. The maternal demographic characteristics, regimens for the administration of MgSO4, and lab test results of patients were collected. Multivariate logistic regression analysis and receiver operating characteristic (ROC) curve analysis were conducted for the risk factors influencing the serum magnesium concentration. Results: A total of 93 patients with severe preeclampsia were included in the study. 52 (55.91%) patients did not attain therapeutic serum magnesium levels. A multivariate logistic regression analysis identified creatinine clearance (Ccr), whether the loading dose was given, and measurement time of serum magnesium concentration (referring to the time from start of MgSO4 infusion to blood draw for serum sampling) as independent risk factors for sub-therapeutic serum magnesium concentration (P < 0.05). ROC curve analysis indicated that the continuous variable Ccr had a significant predictive value for the serum magnesium concentration, which resulted in a cutoff point of 133 mL/min; while measurement time had limited predictive value, with cutoff point of 2.375 h. Conclusions: Ccr, whether the loading dose was given, and measurement time were independent risk factors for sub-therapeutic serum magnesium concentration. A loading dose of MgSO4 everytime before the maintenance dose, as well as the duration of MgSO4 maintenance dose of more than 2.375 hours are recommended for all the patients with severe PE. Routine evaluation of serum magnesium levels is a recommended practice for women with severe PE and whose Ccr is ≥ 133 mL/min.

Published: September 2020

Abstract
Objective

Purpose of the current study was to find the trend in progression of COVID-19 among South Asian countries as compared to more developed western countries.

Method

COVID-19 data of South Asian countries was taken for this observational study. Data was taken up to 21 st April since the outbreak of the virus. There were 4 out of 7 countries which passed through the inclusion criteria and included for analysis.

Results

Increase in average weekly reported cases after 5 th week since first case reported was exponential. Correlation between reported cases and tests performed was found strong and significant (r=0.90, p-value=0.037). However, on average 315.25 tests per million population was performed which was at least 12 times lower than the tests performed in the countries having large number of COVID-19 cases.

Conclusion

At present, number of reported cases from South Asia was found extrememly lower than western countries. However, it could be due to a smaller number of tests performed. Hence, increase in strength of performing diagnostic tests is highly recommended. Strict measures are required to be taken to make the people of these countries to follow the instructions of social distancing and comply with preventive measures.

Published: September 2020

Abstract
Background: Ca2+ was supposed to play an important role in the formation of cataract. Exosomal miR-29b from aqueous humour may play an important role in the mechanism of diabetes and cataracts. The purpose of this study was to investigate the role of exosomal miR-29b and Ca2+ in regulating the function of human lens epithelial cells.Methods: Exosomes were isolated from human aqueous humour by ultracentrifugation, and visualized by nanoparticle tracking and transmission electron microscopy. Exosomal miRNA sequencing was performed to identify differentially expressed miRNAs between diabetes and cataracts group (DMC) and age-related cataracts group (ARC). TargetScan was used to predict potential target of certain miRNA. The expression of CACNA1C mRNA was determined by quantitative real-time PCR and CACNA1C protein was determined by Western blotting. Concentration of Ca2+ of human aqueous humour and cell culture supernatant was detected by the Calcium Assay Kit. Cell Counting Kit-8 was used to determine cell viability.Results: Exosomes were isolated from human aqueous humour, which had a typical cup-shaped phenotype and a particle size distribution in accordance with micro extracellular vesicles. Exosomal miRNA sequencing revealed that miR-29b was significantly downregulated in diabetes and cataracts group (DMC) compared with age-related cataracts group (ARC). Ca2+ concentration of human aqueous humour in DMC was higher than that in ARC. Cell culture supernatant transfected with miR-29b inhibitors had a higher concentration of Ca2+ than that transfected with miR-29b mimics. miR-29b reduced the viability of human lens epithelium cells (HLECs) by up-regulating CACNA1C expression.Conclusions: Exosomes isolated from human aqueous humour contained abundant miRNAs. A significantly expressed miRNA, miR-29b, could affect the concentration of Ca2+ and regulate HLEC processes by up-regulating CACNA1C.

Published: September 2020

Abstract
Background: This study was to evaluate the effectiveness and safety of vancomycin- lock therapy for the prevention of catheter-related bloodstream infection (CRBSI) in very low body weight (VLBW) preterm infant patients.Methods: One hundred and thirty-seven cases of VLBW preterm infants who retained peripherally inserted central catheters (PICCs) were retrospectively reviewed, including 68 treating with heparin plus vancomycin (vancomycin-lock group) and 69 with heparin only (control group). The incidence of CRBSI, related pathogenic bacteria, adverse events during the treatment, complications, antibiotic exposure, PICC usage time, hospital stay, etc. were compared between the above two groups.Results: The incidence rate of CRBSI in the vancomycin-lock group (4.4%, 3/68) was significantly less than in the control group (21.7%, 15/69, p=0.004). Total antibiotic exposure time during the whole observation period was significantly shorter in the group than in the control group (11.2±10.0 vs 23.6±16.1 d; p<0.001). No hypoglycemia occurred during the locking, and the blood concentrations of vancomycin were not detectable.Conclusions: Vancomycin-lock may effectively prevent CRBSI in Chinese VLBW preterm infants and reduce the exposure time of antibiotics, without causing obvious side complications.
