Dalam penelitian ini dilakukan impregnasi basah (wet impregnation) Fe3+ ke dalam MCM-41-tersililasi dengan optimasi konsentrasi Fe3+, waktu dan temperatur. Analisis kristalinitas inang didasarkan pada intensitas puncak bidang [100] difraktogram, analisis kuantitatif Fe dalam MCM-41-tersililasi dilakukan dengan metode AAS, sedang karakterisasi Fe-MCM-41-tersililasi dilakukan dengan metode-metode spektroskopi DRUV-Vis, spektroskopi EPR, dan FTIR. Diperoleh kesimpulan bahwa semakin besar konsentrasi Fe3+ dalam larutan prekursor cenderung meningkatkan kandungan Fe dalam Fe-MCM-41-tersililasi, namun jika digunakan larutan prekursor dengan konsentrasi Fe3+ ≥ 0,1 M berakibat terjadinya kerusakan struktur heksagonal MCM-41-tersililasi. Waktu kontak optimal adalah 8 jam, sedang temperatur optimalnya 40 ºC. Impregnasi basah Fe3+ ke dalam MCM-41-tersililasi dapat mengakibatkan substitusi isomorfis Fe3+ menggantikan Si4+ pada jaringan silikat dan juga menghasilkan nanopartikel oksida besi diluar jaringan silikat, yaitu mengisi sebagian pori MCM-41-tersililasi.

The Dance-In and the Re/production of White Corporeality
Authors: Kraut Anthea 
Published: May 2019

This essay examines the figure of the “dance-in,” a stand-in who dances in place of a star prior to filming, focusing on two women who acted as surrogates and dance coaches for the mid-twentieth century white film star Betty Grable: a white woman named Angie Blue and an African American woman named Marie Bryant. Bringing together film studies theories of indexicality, performance studies theories of surrogation, and critical race theories of flesh and body, I argue that the dance-in helps expose how the fiction of white corporeality as a bounded and autonomous mode of being is maintained.ERRATUM (August 27, 2020) In the article "The Dance-In and the Re/production of White Corporeality" by Anthea Kraut (The International Journal of Screendance, Vol. 10, 2019, https://doi.org/10.18061/ijsd.v10i0.6514), figure 14 was not included with the published HTML version of the article due to a production error.

Uzamsal Referans Çerçeveleri ve Türkçedeki Görünümleri Üzerine Bir İnceleme
Authors: ATAK Ata , UZUN Gülsün Leyla 
Published: May 2019

Bu çalışma uzamsal referans çerçeveleri üzerine Türkçeden bakıldığında ne tür görünümlere erişilebileceği sorusundan hareketle yapılmıştır. Türkçe için kullanılan uzamsal referans çerçevelerini tespit etmek amacıyla gerçekleştirilen uygulamada, konumlanış ilişkisi aktaran ikili nesne düzenlemelerinden oluşan dört farklı üretim görevi (production task) 40 kadın ve 40 erkek olmak üzere toplam 80 katılımcı tarafından yerine getirilmiştir. Çalışma, bu uygulamada katılımcıların yerine getirdiği üretim görevlerinden elde edilen verilere dayalı bir tartışma sunmaktadır. Çalışmanın öne çıkardığı bulguların ilki Türkçede iki nesne arasındaki konumlanış ilişkisini aktarmak amacıyla içsel (intrinsic) ve göreli (relative) referans çerçevelerinin kullanılıyor oluşudur. Öte yandan, konumlanan ile konumlayan olan nesnelerin özelliklerinin uzamsal referans çerçevesi seçimini Türkçede de doğrudan etkilemekte olduğu çalışmanın bir diğer bulgusunu oluşturmuştur. Öyle ki, kullanım sıklıkları, konumlanan ve konumlayan olan nesnelerin özelliklerine göre ve nesne düzenlemelerine göre farklılık göstermektedir. Bu çalışmanın araştırma soruları çerçevesinde cinsiyetin uzamsal referans çerçevesi seçiminde bir değişken olmadığı saptanmıştır. Bunun yanında fen bilimleri ile sosyal bilimlerden gelen katılımcılar arasında göreli referans çerçevesi kullanımı açısından anlamlı bir fark olmazken içsel referans çerçevesi kullanma eğilimi fen bilimlerinden gelen katılımcılarda daha fazladır.

Published: May 2019

Abstract
Background: Creating a scalable computational infrastructure to analyze the wealth of information contained in data repositories is difficult due to significant barriers in organizing, extracting and analyzing relevant data. Shared data science infrastructures like Boa_g is needed to efficiently process and parse data contained in large data repositories. The main features of Boa_g are inspired from existing languages for data intensive computing and can easily integrate data from biological data repositories.

Results: As a proof of concept, Boa for genomics, Boa_g, has been implemented to analyze RefSeq’s 153,848 annotation (GFF) and assembly (FASTA) file metadata. Boa_g provides a massive improvement from existing solutions like Python and MongoDB, by utilizing a domain-specific language that uses Hadoop infrastructure for a smaller storage footprint that scales well and requires fewer lines of code. We execute scripts through Boa_g to answer questions about the genomes in RefSeq. We identify the largest and smallest genomes deposited, explore exon frequencies for assemblies after 2016, identify the most commonly used bacterial genome assembly program, and address how animal genome assemblies have improved since 2016. Boa_g databases provide a significant reduction in required storage of the raw data and a significant speed up in its ability to query large datasets due to automated parallelization and distribution of Hadoop infrastructure during computations.

Conclusions: In order to keep pace with our ability to produce biological data, innovative methods are required. The Shared Data Science Infrastructure, Boa_g, provides researchers a greater access to researchers to efficiently explore data in new ways. We demonstrate the potential of a the domain specific language Boa_g using the RefSeq database to explore how deposited genome assemblies and annotations are changing over time. This is a small example of how Boa_g could be used with large biological datasets.

Published: May 2019

Abstract
Background: Visual impairment and blindness are significant public health issues worldwide. The study aims to explore is the prevalence and causes of moderate to severe visual impairment and blindness across three ecological regions of Nepal.
Methods: A comparative cross-sectional study was conducted in three districts covering all ecological regions of Nepal. Intensive training for health workers was provided to conduct door-to-door visits for visual acuity testing using Snellen chart and refer the abnormal cases for comprehensive ocular examination by technicians and ophthalmologists to diagnose and treat ocular morbidities. Collected data were analyzed using SPSS and Stata software.
Results: Altogether 5234 participants were enrolled in the study. The overall prevalence of moderate to severe visual impairment was 9.5% (4.7% in the Mountain district, 11.2% in the Hill district and 21.2% in the Tarai district), though the prevalence of MSVI was 1.5% in participants aged 15-49 years and 25.1% in those aged ≥50. The overall prevalence of blindness was 0.9%, and the prevalence of blindness in the 15-49 and ≥50 age groups was 0.2% and 2.3% respectively. Most cases of visual impairment and blindness (95.5%) were an avoidable cause, of which 93.7% were treatable and 1.8% were preventable. Overall, cataract was the leading cause of visual impairment and blindness (53.5%), followed by uncorrected refractive error (39.5%).
Conclusion: The prevalence of visual impairment and blindness varied significantly with age, ethnicity and locality. The correction of refractive error and cataract surgery would reduce nine in ten cases of moderate to severe visual impairment and blindness.

Published: May 2019

Abstract
Background: Early childhood caries is a common chronic childhood disease and maternal oral health is an important risk factor. Improving the oral health knowledge and practices of pregnant women/young mothers can positively influence the oral health of children and reduce their caries risk. Such preventative strategies have been undertaken by non-dental professionals producing mixed results encompassing various interventions across the perinatal period. However, no comprehensive review of these studies has been undertaken. The aim of this review was to assess the effectiveness of maternal oral health programs undertaken during the antenatal and/or postnatal period by non-dental health professionals to reduce early childhood caries.
Methods: A systematic search of five databases was undertaken using key search terms. Studies were included if they (a) involved quantitative study designs with a control; (b) were published in English; (c) reported on interventions delivered by non-dental professionals (d) delivered the intervention to expectant mothers or mothers with young infants up to 24 months; (e) measured outcomes when the child was under 5 years; (f) measured changes in oral health outcomes of children clinically and oral health behaviours of mothers or children. No restrictions were placed on the study quality and setting.
Results: Nine studies met the inclusion criteria and involved interventions delivered by diverse non-dental professionals across the antenatal (n=1), postnatal (n=6) and perinatal period (n=2). Most studies were of low methodological quality (n=6). The interventions focussed on oral health education (n=8), dental referrals (n=3) and oral health assessments (n=1). Interventions conducted in either the postnatal or antenatal periods showed meaningful improvements in children’s clinical and mother’s behavioural oral health outcomes. The outcomes appear to be sustained when a suite of interventions were used along with referral reminders. There were mixed results from interventions across the perinatal period.
Conclusions: Non-dental professionals can promote maternal oral health and reduce ECC in children by providing oral health education, risk assessment and referrals. Combining these interventions could provide a sustained improvement in oral health outcomes for children. However, more high-quality studies are needed to confirm whether the antenatal and/or postnatal period is best suited to deliver these interventions.
Discharge against medical advice and premature leave of neurological patients from an interdisciplinary emergency department: a retrospective observational study.
Authors: Hoyer Carolin , Stein Patrick , Alonso Angelika , Platten Michael , Szabo Kristina 
Published: May 2019

Abstract
Background: Discharge against medical advice (DAMA) or premature leave (PL) from the emergency department represent relevant medical problems with impact on patient safety and potential medicolegal consequences. They may also indicate structural or procedural problems in the ED. To date, no dedicated analysis of DAMA/PL exists for neurological patients presenting to the ED.
Methods: A retrospective observational study was performed of all patients with neurological complaints presenting to a German interdisciplinary emergency department between January and December 2017. DAMA/PL patients were compared to the total of patients who were admitted or discharged regularly (non-DAMA/PL).
Results: Of all neurological cases, 3% left against medical advice and 2.2% left prematurely. DAMA/PL patients were younger (p<.001), and their presentation was more frequently self-motivated (p<0.001. Waiting times did not differ between DAMA/PL and non-DAMA/PL patients (p=.166) but treatment duration was significantly shorter in the former (p<.001) Headaches, seizures and sensory deficits were the most frequent presenting symptoms in DAMA/PL patients, and in 56.1% of those presenting with a seizure had a history of epilepsy. The most common documented reason for leaving was the length of waiting time.
Conclusions: Both individual and structural/systemic reasons contribute to DAMA/PL in neurological patients. Optimization of pre-hospital assessment and the development of alternative models of care for patients with non-urgent conditions appear to be promising targets for future improvements regarding demand management and the direction of patient flow.
Comparison of InvisalignⓇ Aligners versus Fixed Appliance Treatment in pain perception: a systematic review and meta-analysis
Authors: Pereira Dinis , Machado Vanessa , Botelho João , Mendes José João , Delgado Ana Sintra 
Published: May 2019

Abstract
Background: This systematic review aimed to compare the pain discomfort levels between InvisalignⓇ aligners comparing with traditional fixed appliances at multiple time points, through Pain Visual Analog Scale (VAS).
Methods: Four electronic databases (Pubmed, Medline, CENTRAL and Scholar) were searched up to February 2019. There were no restrictions on year and publication status. Randomized clinical trials (RCTs) and case-control studies comparing pain perception through VAS in patients treated with Invisalign aligners and with labial appliances were included. Risk of bias within and across studies was assessed using Cochrane tool and Newcastle-Ottawa Scale (NOS) approach. Random-effects meta-analysis were conducted. VAS score at 1, 3 and 7 days, and analgesic consumption was collected. Pairwise and Binary Random-Effects Meta-analyses were used to synthesize available data.
Results: At the initial search, a total of 87 articles were retrieved. Following the review protocol, 4 articles met the inclusion criteria and were included, with a total of 214 participants (139 females, 75 males). All studies were considered of high methodological quality. The results demonstrate that Invisalign aligners seems to be associated with significantly less pain than fixed appliances at 7 days after beginning the orthodontic treatment, although at 1 and 3 days the pain experience was similar in both orthodontics appliances. In regard to the type of material, SmartTrackⓇ aligners appear to give significantly better comfort for orthodontic patients than previous standard material, being that 3 days after appliance’s insertion this pain differential becomes significant, and this difference is more pronounced at 7 days.
Conclusion: Patients treated with Invisalign experience less pain discomfort than those treated with fixed appliances and consume less analgesics. Overall, Invisalign promotes better pain and discomfort experience for the patient in the course of orthodontic treatment. Larger RCTs are needed to definitely demonstrate these findings throughout the orthodontic treatment.

Published: May 2019

Abstract
Background

Prevention and management of obesity is integral to family medicine. Yet, physicians lack training and confidence to effectively address weight concerns with patients. Quality, evidence-based obesity management training for family medicine residents is needed to better support patients. We developed a comprehensive course based on the 5As of Obesity Management™, a framework and suite of resources to improve residents’ knowledge and confidence in obesity counselling. This study aimed to understand the course’s impact on residents’ attitudes, beliefs, and confidence with obesity counselling.

Methods

The course combines lectures with a bariatric suit experience, standardized and in-clinic patient practice, and narrative reflections. Using a multi-methods design we measured changes in 42 residents’ attitudes, beliefs, and self-confidence and thematically analyzed the narrative reflections to understand residents’ experience with the course content and pedagogy.

Results

Following the course, residents reported improved attitudes towards people living with obesity and improved confidence for obesity counselling. Experiential learning proved crucial in increasing residents’ ability to empathically engage with patients and to critically reflect on implications for their practice.

Conclusion

The 5AsT-MD course has the potential to increase residents’ confidence and competency in obesity prevention and management. Findings reflect the utility of the 5As to improve residents’ confidence and competency in obesity management counselling.

Published: May 2019

Abstract
Background

As ageing emerges as the next public health threat in Africa, there is a paucity of information on how prepared its health systems are to provide geriatric friendly care services. In this study, we explored the readiness of Uganda’s public health system to provide geriatric friendly care services in Southern Central Uganda.

Methods

Four districts with the highest proportion of old persons in Southern Central Uganda were purposively selected, and a cross section of 18 randomly selected health facilities (HFs) were visited and assessed for availability of key items deemed important for provision of geriatric friendly services; as derived from World Health Organization’s Age-friendly primary health care centres toolkit. Data was collected using an adapted health facility geriatric assessment tool, entered into Epi-data software and analysed using STATA version 14. Kruskal-Wallis and Dunn’s post hoc tests were conducted to determine any associations between readiness, health facility level and district.

Results

The overall readiness index was 16.92 (SD ±4.19) (range 10.8 - 26.6). This differed across districts; Lwengo 17.91 (SD ±3.15), Rakai 17.63 (SD ±4.55), Bukomansimbi 16.51 (SD ±7.18), Kalungu 13.74 (SD ±2.56) and facility levels; Hospitals 26.62, Health centers four (HCIV) 20.05 and Health centers three (HCIII) 14.80. Low readiness was due to poor scores with regard to; leadership (0%), financing (0%), human resources (1.7%) and health management information systems (HMIS) (11.8%) WHO building blocks. Higher level HFs were statistically significantly friendlier than lower level HFs (p= 0.015). The difference in readiness between HCIIIs and HCIVs was 2.39 (p=0.025).

Conclusion

There is low readiness of public health facilities to provide geriatric friendly care services in Uganda. This is due to gaps in all of the health system building blocks. There is a need for health system reforms in Uganda to adequately cater for service provision for old people if the 2020 global healthy ageing goal is to be met.
