Penelitian ini bertujuan mengetahui miskonsepsi yang terjadi pada materi larutan penyangga menggunakan instrumen soal two-tier diagnostic test . Instrumen dikembangkan berdasarkan indikator kompetensi materi larutan penyangga menjadi 10 pertanyaan dan dinyatakan valid untuk digunakan. Penelitian dilakukan terhadap siswa dan mahasiswa tingkat I dan III berjumlah 159. Hasil penelitian menunjukkan bahwa terjadi miskonsepsi pada konsep sifat larutan penyangga sebanyak 24,6%, konsep komposisi larutan penyangga sebanyak 24,1%, konsep prinsip kerja larutan penyangga sebanyak 29,3%, dan konsep pH larutan sebanyak 25,4%. Penyebab miskonsepsi dikarenakan konsep awal responden yang lemah, penjelasan guru yang sering menyederhanakan konsep, kebiasaan responden untuk menghafal, pemahaman bahasa dan konsep matematis yang lemah, serta model pembelajaran yang belum memberikan kesempatan responden untuk memahami komponen dan prinsip kerja larutan penyangga secara mikroskopis. Pengetahuan tentang miskonsepsi diperlukan sebagai evaluasi terhadap guru dan dosen agar lebih termotivasi untuk menerapkan model pembelajaran yang mampu mengatasi miskonsepsi untuk mencegah timbulnya miskonsepsi lebih luas dalam pembelajaran kimia yang menjadikan kimia dianggap sulit.

Published: January 2020

Abstract
Background: Lebanon has experienced several measles and mumps outbreaks in the past twenty years . In this article, the trend of measles outbreaks in Lebanon was studied in an attempt to outline factors contributing to the failure of elimination plans, and to provide potential solutions. The relationship between measles and mumps outbreaks in Lebanon was described and explored. Methods: A retrospective descriptive study of confirmed cases of measles and mumps in Lebanon between 2003 and 2018 collected from the Lebanese Ministry of Public Health Epidemiological Surveillance Unit public database was carried out. The information collected was graphically represented taking into consideration dates of cases, age groups affected, and vaccination status. Results: The mean number of measles cases was 150.25 cases/year in the 1-4 years age group, 87 cases/year in individuals aging between 5 and 14, and 63.68 cases/year in those > 14 years old. In the latter group, only 18.05% were unvaccinated. The mean number of mumps cases was 30.4 cases/year in the <4 year age group and 53.8 cases/year in the 10-19 years age group. During the study period, every spike in measles cases was followed by a similar spike in mumps. 9.66% of measles cases occurred in individuals who received at least 2 doses of the vaccine, 52.26% in the unvaccinated, and 38% in those whose vaccination status was undetermined. Conclusions: Measles in Lebanon is a disease of the pediatric population, but adults remain at risk. Outbreaks of mumps followed those of measles and were mainly among adolescents. Presence of a large number of Syrian refugees in the country may further complicate the situation. Vaccination activities need to be intensified. Keywords: Measles, mumps, elimination, vaccine, Lebanon.
Maternal coffee intake and the risk of bleeding in early pregnancy: a cross-sectional analysis
Authors: Choi Hansol , Koo Seul , Park Hyun-Young 
Published: January 2020

Abstract
Background: Caffeine can easily cross the placenta, and maternal caffeine intake, thus, has an effect on fetal growth. However, it is still unclear whether coffee consumption is an independent risk factor for bleeding in early pregnancy. The objective of this study was to examine the association between pre-pregnancy coffee consumption patterns and the risk of bleeding in early pregnancy. Methods: A cross-sectional analysis was conducted among 3,510 pregnant women from the Korean Pregnancy Outcome Study who underwent baseline examination between 2013 and 2017 and for whom the results of the pregnancy were available. Coffee consumption patterns before pregnancy were examined using a questionnaire. The participants were classified according to the frequency of coffee consumption into seldom (<1 cup/week), light (<1 cup/day), moderate (1 cup/day), and heavy coffee drinker (≥2 cups/day) groups. Bleeding in early pregnancy was defined as the occurrence of vaginal bleeding in the first 20 weeks of pregnancy. Multiple logistic regression models were applied to examine the association between pre-pregnancy coffee consumption and the risk of bleeding in early pregnancy, after adjusting for age, body mass index, systolic blood pressure, cigarette smoking and alcohol consumption behavior, previous and current physical activity levels, stress levels, history of depression, presence of antenatal depressive symptoms during the first trimester, type of emesis, parity, and the number of livebirths, stillbirths, miscarriages, and abortions. Odds ratios among light, moderate, and heavy coffee drinkers were determined through comparisons with the seldom coffee drinker group. Results: Women who were light, moderate, and heavy coffee drinkers before pregnancy had adjusted odds ratios of 1.086, 1.225, and 1.358, respectively, for bleeding in early pregnancy. However, the association between coffee consumption and the risk of miscarriage or stillbirth was not significant. Conclusions: Our results showed that heavy coffee drinking was independently associated with a higher risk of bleeding in early pregnancy among pregnant Korean women, suggesting that caffeine intake before conception and during pregnancy should be reduced. Our study highlights the need for nutritional interventions for healthy coffee drinking among pregnant women in Korea. Keywords: caffeine, coffee consumption, fetus, placenta, pregnancy
Effectiveness of additional thoracic paravertebral block in improving anesthetic effects of regional anesthesia for proximal humeral fracture surgery in elderly patients: study protocol for a randomized controlled trial

Published: January 2020

Abstract
Background: The innervation of shoulder-upper extremity area is complicated and unclear. Regional anesthesia with brachial plexus and cervical plexus block is probably inadequate for the proximal humeral surgery. Missing blockade of T1-T2 nerves may be the reason. We conduct this prospective randomized controlled trial (RCT) to explore whether additional T2 thoracic paravertebral block (TPVB) can improve the success rate of regional anesthesia for elderly patients in proximal humeral fracture surgery.
Methods: The patients aged 65 or older, referred for anterior approach proximal humeral fracture surgery, will be enrolled. Each patient will be randomly assigned 1:1 to receive IC block (combined interscalene brachial plexus with superficial cervical plexus block) or ICTP block (combined thoracic paravertebral block with brachial plexus and superficial cervical plexus block). The primary outcome is the success rate of regional anesthesia without rescue analgesic methods. The secondary outcomes are as follows: sensory block at surgical area, proportion of patients who need rescue anesthesia (intravenous remifentanil or conversion to general anesthesia), cumulative doses of intraoperative vasoactive medications and adverse events. The total sample size is estimated to be 80 patients.
Discussion: This RCT aims to confirm whether additional T2 TPVB can provide better anesthetic effects of regional anesthesia with brachial and cervical plexus block in elderly patients undergoing proximal humeral surgery.
A partial mediation effect of father-child attachment and self-esteem between parental marital conflict and subsequent features of internet gaming disorder in children: a 12-month follow-up study

Abstract
Objectives

This study evaluated whether parent-child attachment and self-esteem may mediate the relationship between parental marital conflict and increases in features of internet gaming disorder (IGD) in children at one year.

Method

The baseline and one-year follow-up data for 268 children from the iCURE study were collected. The students were “non-cases of high risk of IGD” in the initial self-reported assessment, anyone living with both parents, current game user at baseline, and those who completed a 12-month follow-up assessment. The Internet Game Use-Elicited Symptom Screen (IGUESS) was used to identify increases in IGD features at 12 months. To examine a potential mediation effect, structural equation modeling was performed.

Results

The direct effect was statistically significant, and parental marital conflict at baseline significantly predicted the increases in IGD features in children at the 12-month follow-up after adjusting for gender, sex, socioeconomic status, and baseline IGUESS score (ß=0.206, P=0.003). The indirect effect showed that attachment to fathers through self-esteem was a significant mediating effect (ß=0.078, P=0.045). Parental marital conflicts were associated with increases in IGD features in children through poor father-child attachment, and in turn, the lower levels of self-esteem in the children.

Conclusion

Parents, especially fathers, should make an effort to bond with their children to reduce the risk of their children’s developing the IGD features.

Abstract
Background: This study aims to compare the percentage of dentin removed, instrumentation efficacy, root canal filling and load at fracture between contracted endodontic cavities, and traditional endodontic cavities on root canal therapy in premolars.
Methods: Forty extracted intact human first premolars were imaged with micro-CT and randomly assigned to the contracted endodontic cavity (CEC) or traditional endodontic cavity (TEC) groups. CEC was prepared with the aid of a 3D-printed template, canals were prepared with a 0.04 taper M-Two rotary instrument, and cavities were restored with resin. Specimens were loaded to fracture in an Instron Universal Testing Machine after a fatigue phase. The data were analyzed by the independent samples T test and Mann-Whitney U test, appropriate post hoc tests.
Results: In the premolars tested in vitro, the percentage of dentin removed in the premolars with two dental roots in the CEC group (3.85% ± 0.42%) was significantly smaller (P < 0.05) than in the TEC group (4.94% ± 0.5%). The untouched canal wall (UCW) after instrumentation for TECs (16.43% ± 6.56%) was significantly lower (P< .05) than the UCW (24.42% ± 9.19%) for CECs in single-rooted premolars. No significant differences were observed in the increased canal volume and surface areas in premolars between the TEC and CEC groups (P > 0.05). CECs conserved coronal dentin in premolars with two dental roots but no impact on the instrument efficacy. There were no differences between the CEC groups and the TEC groups in the percentage of filling material and voids (P > 0.05). In addition, the mean load at failure of premolars did not significantly differ between the CEC and TEC groups and there was no significant difference in the type of fracture (P > 0.05).
Conclusion: The results of this study suggest that CEC could not improve the fracture resistance of the endodontically treated premolars. The instrumentation efficacy and the percentage of filling material did not significantly differ between CECs and TECs in premolars.
Keywords: 3D-printed template, contracted endodontic cavities, instrumentation efficacy, root canal filling, fracture resistance
Magnitude of iodine deficiency disorder and associated factors in Dawro zone, southwest Ethiopia: the hidden hunger
Authors: Asfaw Agize , Belachew Tefera 
Published: January 2020

Abstract
Background: Iodine deficiency disorder (IDD) is continued to be a major public health problem in Ethiopia. The problem is worse but the data is scarce in some pocket areas of the country. This study was aimed to assess the magnitude of IDD and associated factors in southwest Ethiopia by using different biochemical and clinical indicators.
Methods: Both community and school based cross- sectional study was conducted on school age children (6-12 years) from March 1 to 24, 2017. Simple random and systematic sampling techniques were applied to select districts and eligible children respectively. Household data was collected from children’s primary care takers by using structured questionnaire. A trained surgeon examined all children (n=652) for goiter. Urine sample was collected from 20% of children (n=130).
Results: A total of 652 school children were participated in the study. Total goiter rate and median urinary iodine concentration (UIC) was 54.8 % and 96.12μg/l respectively. In multivariable logistic regression analyses student’s age was significantly (P<0 05) associated with both goiter and median UIC. However; sex of students and family income were significantly (P<0.001) associated with goiter and cassava consumption was significantly (P<0.001) associated with UIC.
Conclusion: As indicated by the median UIC, there was mild iodine deficiency in this study community. However; chronic iodine deficiency was still a severe public health problem (high goiter prevalence). In addition, there was low concentration of iodine in the salt and increased cassava cultivation and consumption indicating the potential risk in the area. Therefore, it is necessary to intensify IDD elimination activities along with teaching communities on techniques of cassava processing for household consumption.

Abstract
Background There are several open scientific questions regarding the optimal antibiotic treatment of spine infections (SI) with or without an implant. The duration of post-surgical antibiotic therapy is debated.Methods We will perform and perform two unblinded randomized -controlled RCTs. We hypothesize that shorter durations of systemic antibiotic therapy after surgery for SI are non-inferior (10% margin, 80% power, ɑlpha 5%) to existing (long) treatment durations. The RCTs allocate the participants in two arms of 2 x 59 episodes each: 3 vs. 6 weeks of targeted post-surgical systemic antibiotic therapy for implant-free spine infections (two positive microbiological samples); or 6 vs. 12 weeks for implant-related spine infections. This equals a total of 236 adult SI episodes (randomization schemes 1:1) with a minimal follow-up of 12 months. All participants have a concomitant multidisciplinary surgical, re-educational, internist and infectious diseases care. We perform three interim analyses that are evaluated, in a blinded analysis, by an independent Study Data Monitoring Committee. Besides the primary outcome remission, we also assess adverse events of antibiotic therapy, changes of the patient’s nutritional status, the influence of immune suppression, total costs, functional scores, and the timely evolution of the (surgical) wounds. We define infection as the presence of local signs of inflammation (pus, wound discharge, calor, rubor) together with microbiological evidence of the same pathogen(s) in at least two intraoperative samples; and remission as absence of clinical, laboratory and/or radiological evidence of (former or new) infection.Discussion Provided that there is adequate surgical debridement, both RCTs enable to potentially prescribe less antibiotics during the therapy of SI; with potentially less adverse events and reduced overall costs.
