Published: July 2021

La presente investigación tuvo como objetivo principal, determinar el riesgo geotécnico de excavaciones profundas utilizando anclajes post-tensados en edificaciones de Lima Metropolitana, aplicando métodos probabilísticos a partir de un abordaje estadístico simple, basado en la hipótesis fundamental de la distribución normal gaussiana de las variables envueltas.En primer lugar, se utilizó el parámetro fundamental de los anclajes post-tensados, la capacidad última de adherencia en la interacción suelo-lechada de cemento τult, (resistencia en la ruptura). Este parámetro se obtuvo de dieciséis (16) ensayos de arrancamiento a escala natural de anclajes post-tensados cimentados en el conglomerado de Lima Metropolitana, obtenidos de la tesis de maestría de Puelles (2011). En segundo lugar, se realizó un diseño de anclajes post-tensados de edificaciones en Lima Metropolitana de 3, 4 y 5 anillos de 10.50, 13.50 y 16.50 m de profundidad respectivamente. Para ello, se utilizó la metodología FHWA con el objetivo de obtener la capacidad de carga de diseño (TD) de anclajes post-tensados. Además, se ejecutó modelos y modelamientos en el software Slide v6.0 (método equilibrio límite), para realizar el análisis de estabilidad de los mismos. Para ello, se tuvo en cuenta las siguientes variables: los parámetros geotécnicos representativos de Lima Metropolitana, la profundidad de estudio (10.50 a 16.50 m.) y la sobrecarga de edificaciones colindantes. Por último, con los parámetros obtenidos (τult y TD) se definió las curvas estadísticas de distribución de solicitación y resistencia. Luego, se aplicó los métodos probabilísticos e interpretación respectiva, determinado así el riesgo geotécnico para cada caso de estudio.

Esta investigación se centra en el análisis de los textos informativos publicados por los diarios de circulación nacional: El Comercio y La República, relacionados a la candidatura de Ollanta Humala Tasso durante la semana previa al balotaje de los comicios electorales en Perú el año 2011. Y tiene el propósito de evidenciar, si en momentos de tensión política, como es una segunda vuelta, el equilibrio periodístico informativo y sus elementos se ven afectados por el contexto. Para ello, se explica la estrecha relación que guarda el periodismo con la política. Luego, se toma en cuenta los fundamentos del periodismo, para definir la naturaleza, matices y el lenguaje del periodismo informativo. A partir de ello, se construye el concepto de Equilibrio Periodístico Informativo, el cual está apoyado en una serie de elementos y de referentes. De igual forma, se considera el contexto político de la época, el cual sirve de referencia. A partir de ello, los resultados del análisis demuestran que el concepto de información, supuestamente asentado en ambos enunciadores, pierde algunas referencias por una serie elementos y presiones propias de tales coyunturas, donde hay una polarización política.

Aim: this study aimed to compare the sealing ability of two types of commercially available calcium silicate bioceramic based root canal sealers and a resin based root canal sealer. Methods: Twenty one single-rooted teeth were used, samples (n= 21) were randomly divided into three groups according to the sealer used (group A; ADSEAL, group B; Wellroot, group C; Ceraseal). Roots were then cleaved longitudinally in the labiolingual direction; all samples were then sectioned at three, six, and nine mm from the root tip. The penetration of sealers into the dentinal tubules was examined at 1000x with a scanning electron microscope. Data were tested for normality using Shapiro Wilk test. ANOVA test was used for analyzing normally distributed data followed by Bonferroni post hoc test for pair-wise comparison. Significance level p≤0.001. Results: groups B and C showed better sealing ability than group A in all the three sections. The coronal section showed higher sealing ability than the middle section followed by the apical section in the three tested groups. Conclusion: it can be concluded that both calcium silicate-based sealers had better sealing ability and higher bond strength than the resin epoxy- based sealer.
How to Deal with the Verses of War: Abdullah Saeed’s Instructional Values on Reading the Qur’an
Authors: Siddiq Akhmad
Published: July 2021

The connection between violence and religious principle from time to time has been an essential topic discussed among Muslim scholars. Many radical movements, such as the Islamic State of Iraq and Syiria (ISIS), referred to the Qur’an and hadith for justifying or rationalizing their violent acts. They consumed the verses of the Qur’an in order to graps and spread their mission. They hijacked the scripture in their behalf. This article aims to describe the verses of war in the Qur’an which structurally consists of social and political nuances. This article also discusses what so-called “permissive-structure” or “instruction-structure” and elucidates several verses of war, based on Tafsīr al-Qur’ān al-‘Aẓīm written by Imam al-Ḥāfiẓ Abū al-Fidā’ and al-Mīzān fī Tafsīr al-Qur’ān written by Sayyid Muḥammad Ḥusayn al-Ṭabāṭabā’ī. Using hermeneutical approach and discourse-analysis, this study argues that the verses of war in the Qur’an have been contextually misinterpreted by the radical groups to achieve their political interests.
The Problem of Contextualizing a Prestigious Yet Non-Divine Jesus of Islamic Tradition: Theorizing a Radical Transition in the Course of Christology from the New Testament to the Qur’an
Authors: Waqas Syed M.
Published: July 2021

This article addresses the question of the messianic motif of Christianity making its way into the Qur’an without wearing a badge of high New Testament Christology. It attempts to explore and understand a potentially underlying connection among the Islamic ‘Isā, the New Testament Jesus, and the Jewish messiah in a quest for the configuration of a historical Christ through the ideological and historical minefields that exist between the Islamic and the Judeo-Christian Scriptures. The person of Jesus is, therefore, understood to be historical in the article without positing a response to the fundamental questions raised by the historical Jesus skepticism. What I will try to avoid in the following pages, on the contrary, is to treat and brand the Qur’anic portrayal of Jesus as a “stand-alone” concept—indifferent to the historical context of the Bible—hanging in a theological balance, as some critics would be inclined to call it. The article is linearly structured according to the major Qur’anic precepts and concepts developed around the person of Jesus through its text, which originally do not follow a particular sequence. A comparative study of Islamic Jesus against a two-pronged history of the concept is carried out for a critical analysis of the characterization of Islamic Jesus and the received concept of messiah. Such an analysis is important particularly on two fronts: comparison with the Judeo-Christian Bible and comparison with the orthodox Islamic position in certain aspects that fall outside the Qur’anic provenance. The life and ministry of Jesus pictured in the present article is, for the most part, a reconstruction of the important notion of Christology from within the Qur’an without breaking it down to a form of reductionism capitalizing on rudimentary borrowing from an external source.

Authors: Widiyanto Agnes Fitria , Kurniawan Arif , Gamelia Elviera
Published: July 2021

Waste is still a problem in Indonesia. The increase in population causes the volume of waste to continue to grow, in Karangmangu Village, Banyumas Regency. Data on the increase in the volume of waste in Banyumas Regency reached 21.4%. The volume of inorganic waste is greater than organic waste because Karangmangu Village is a tourism buffer area in Baturraden. This study aimed to describe the knowledge, attitudes, and practices of cadres in the management of inorganic waste. The method used was descriptive qualitative. The research subjects were obtained using a purposive technique by conducting interviews with cadres as the main research subjects, midwives, and supporting informants. Data were collected through in-depth interviews and documentation. The results showed that the cadres had understood the definition, types, management, and negative impacts of inorganic waste. Based on their attitudes, the cadres consider the case of handling inorganic waste to be not optimal. In practice, they have sorted inorganic waste, managed a waste bank, made bricks, and produced handicrafts. Strategies to overcome obstacles in waste management are optimizing the facilities and infrastructure for the procurement of waste banks, as well as training more people to make handicrafts and market handicraft products. This study concludes that the presence of village cadres is able to increase public awareness in waste management.

Introdução: A síndrome de Lemmel é uma causa rara de icterícia obstrutiva secundária a um divertículo duodenal periampular, o qual comprime a via biliar comum. Essa compressão resulta em dilatação de via biliar intra-hepática e extra-hepática na ausência de coledocolitíase ou de outras causas obstrutivas. Relato de caso: Apresentamos dois pacientes idosos com colestase, indicada por icterícia obstrutiva, diagnosticados com síndrome de Lemmel por endoscopia digestiva alta, a qual mostrou divertículos duodenais. Os pacientes foram submetidos a tratamento cirúrgico com coledocoduodenostomia devido à idade avançada, aos cálculos primários do colédoco e à dilatação importante do colédoco. Apresentaram evolução favorável no pós-operatório. Conclusão: A síndrome de Lemmel é uma condição que deve ser considerada diagnóstico diferencial em pacientes idosos apresentando colestase. Exames de imagem como colangiorressonância e tomografia computadorizada com contraste devem ser solicitados, e, na suspeita de divertículo duodenal, pode-se confirmar sua presença com endoscopia digestiva alta com vista lateral. Não há tratamento formal para pacientes com síndrome de Lemmel. Em ambos os casos, realizamos tratamento cirúrgico.
Узагальнена логічна схема моделювання процесів технологічного забезпечення контурної стабільності при виготовленні інтегральних обкладинок
Authors: Тріщук Руслан Любомирович
Published: July 2021

Встановлено, що одним з найбільш важливих показників інтегральної обкладинки з широкими клапанами є контурна стабільність, яка характеризується відхиленням зовнішніх контурів від прямокутної побудови. Цей параметр формується під час проходження заготовки обкладинки через механізм координувально-транспортувального блоку лінії для виготовлення інтегральних обкладинок. Зазначений показник залежить як від витратних матеріалів (папір, картон-хромерзац, клей, термоклей), так і від тиражу, а також від геометричних і фізико-механічних параметрів деталей координувально-транспортувального блоку, які контактують з обкладинкою.
Розроблено узагальнену логічну схему в параметричному вигляді моделювання процесів технологічного забезпечення контурної стабільності обкладинок та якості й експлуатаційних властивостей деталей координувально-транспортувального блоку лінії для виготовлення інтегральних обкладинок з широкими клапанами. Така схема дозволяє встановити взаємозв’язок між режимами комплексної технології оздоблювально-зміцнювальної обробки, геометричними і фізико-механічними параметрами поверхні циліндричних деталей координувально-транспортувального блоку лінії для виготовлення інтегральних обкладинок з широкими клапанами, визначити їх вплив на експлуатаційні характеристики поліграфічного обладнання та якість готової продукції.
Підвищення показників якості обкладинок характеризується істотним зменшенням відсотку їх відбракування залежно від накладу після застосування комплексного технологічного процесу оздоблювально-зміцнювальної обробки.
Застосування узагальненої логічної схеми моделювання процесів технологічного забезпечення контурної стабільності обкладинок та експлуатаційних властивостей циліндричних деталей координувально-транспортувального блоку лінії для виготовлення інтегральних обкладинок з широкими клапанами є доцільним при комплексній обробці як деталей лінії з виготовлення обкладинок, так для циліндричних рухомих деталей іншого поліграфічного обладнання (машин для флексографічного друку та ін.).

Experimental Study on the Starting-Up and Heat Transfer Characteristics of Pulsating Heat Pipe Under Local Low-Frequency Vibrations
Authors: Chen Jing , Dong Junbiao , Yao Ye
Published: July 2021

This study mainly experimentally investigates and explores the effects of local low-frequency vibrations on the starting-up and heat transfer characteristics of the pulsating heat pipe. A micro motors with the vibration frequency of 200 Hz were imposed on the external surface of evaporation, condensation and adiabatic section of the pulsating heat pipe, respectively, and the starting-up temperature and the average temperatures along the evaporation section as well as the thermal performances of the vibrating heat pipe were experimentally scrutinized under the local vibrations of different positions. The following important conclusions can be achieved by the experimental study: 1) The effect of vibrations at the evaporation section and at the adiabatic section on the starting-up time of pulsating heat pipe is more significant than that at the condensation section. 2) The vibrations at different positions can reduce the starting-up temperature of the pulsating heat pipe. The effect of the vibrations at the evaporation section is the best as the heating power is lower, and the effect of the vibration at the adiabatic section is the best as the heating power is higher. 3) The vibrations at the evaporation section and at the adiabatic section can reduce the thermal resistance of the pulsating heat pipe. However, the vibrations at the condensation section have little effect on the thermal resistance of the pulsating heat pipe. 4) The vibrations at the evaporation section and at the adiabatic section can effectively reduce the temperature of evaporation section of the pulsating heat pipe, but the vibrations at the condensation section have no effect on the temperature of evaporation section of the pulsating heat pipe.
WHO Fever Management Guidelines: Challenges in Harnessing the Benefits During Covid-19 Pandemic
Authors: Singh Samer , Kishore Dhiraj , Singh Rakesh
Published: July 2021

Fever remains an integral part of the acute clinical diseases management, esp. viral, for which effective therapeutics remain desired. However, the presence of often confusing fever reduction recommendations for COVID-19 in the public domain during the pandemic, as late as 28 April 2021, seems to suggest the reduction of any ‘uncomfortable’ fever ranging from 37.8 - 39oC, as opposed to WHO fever reduction guidelines (≥39oC), urgently need attention. The confusion could percolate down into different agencies who look up to these agencies for guidance in framing their own, denying the benefits of fever to populations, and effectively undo whatever successive WHO’s guidelines have achieved in the last two decades. The existence of conflicting guidelines in public domains which are open to interpretations has consequences to public health and the healthcare infrastructure, on implementation. For controlling acute infectious diseases, esp. viral, the fever remains the most important enabler. Historically, our chief obstacles to harnessing the benefits of fever in acute clinical diseases with limited therapeutics had been: a) widespread myths about ‘fevers’ arising from a general misunderstanding of basic facts; b) presence of confusing guidelines by different agencies which are open to alternate interpretation. The article attempts to briefly indicate the benefits of fever in disease resolution, dispel myths, underline vagueness in illustrative national guidelines and the need to align them with evidence-based WHO guidelines, as it has the potential to perpetuate myths/confusion in masses leading to adverse impact on disease management – more morbidity and mortality from diseases including COVID-19.

Ciacia Language Maintenance through "House of Culture" Model
Authors: Kamaluddin Kamaluddin , Nurnia Nurnia
Published: July 2021

Local language maintenance has been remarkably attended recently following massive extinction of languages for having been rarely used and not transmitted well to younger generation. This paper reports the findings of a study related to a model which is evidently useful to preserve local language use among students with less comprehension to their local language. The developed model employs local short stories as tools for language perseverance by means of project making which requires students' active participation mingling with the language. The study indicates that local culture and tradition like short stories is apparently favorable to support and promote the use of local language among students. Thus, it is highly recommended that local culture and tradition be cultivated and developed to preserve language maintenance and involve language users directly and consciously towards language survival.
Triceps Insufficiency After Total Elbow Arthroplasty
Authors: Meijering Daniëlle , Welsink Chantal L. , Boerboom Alexander L. , Bulstra Sjoerd K. , Vegter Riemer J.K. , Stevens Martin , Eygendaal Denise , van den Bekerom Michel P.J.
Published: July 2021

Background:

The incidence of triceps insufficiency after total elbow arthroplasty (TEA) varies in the literature, and a consensus on treatment strategy is lacking. We review the incidence, the risk factors, the clinical presentation, and the diagnosis and treatment of triceps insufficiency after TEA. Based on this information, we have formulated recommendations for clinical practice.

Methods:

We performed a systematic review of the literature from January 2003 to April 2020 to identify studies that investigated triceps function following TEA by searching the PubMed, Cochrane, and Embase databases. Eligible studies (1) reported on triceps function following primary or revision TEA for every indication, regardless of technique (e.g., bone grafts), (2) included ≥6 adult patients, (3) had the full-text article available, and (4) had a minimum follow-up of 1 year.

Results:

Eighty studies with a total of 4,825 TEAs were included. The quality was low in 15 studies, moderate in 64 studies, and high in 1 study. The mean incidence of triceps insufficiency was 4.5%. The rates were highest in patients after revision TEA (22%), in those with posttraumatic arthritis as an indication for surgery (10.2%), and after a triceps-reflecting approach (4.9%). Most studies used the Medical Research Council scale to score triceps function, although cutoff points and the definition of triceps insufficiency differed among studies. Surgical treatment showed favorable results with anconeus tendon transfer and Achilles allograft repair when compared with direct repair.

Conclusions:

The incidence of triceps insufficiency varies greatly, probably due to a lack of consensus on the definition of the term. Therefore, we recommend the guidelines for clinical practice that are presented in this article. These guidelines assist clinicians in providing the best possible treatment strategy for their patients and help researchers optimize their future study designs in order to compare outcomes.

Team Approach: Virtual Care in the Management of Orthopaedic Patients
Authors: Rubinger Luc , Gazendam Aaron , Wood Thomas , Yardley Darryl , Shanthanna Harsha , Bhandari Mohit
Published: July 2021

» Telemedicine and remote care administered through technology are among the fastest growing sectors in health care. The utilization and implementation of virtual-care technologies have further been accelerated with the recent COVID-19 pandemic.

» Remote, technology-based patient care is not a “one-size-fits-all” solution for all medical and surgical conditions, as each condition presents unique hurdles, and no true consensus exists regarding the efficacy of telemedicine across surgical fields.

» When implementing virtual care in orthopaedics, as with standard in-person care, it is important to have a well-defined team structure with a deliberate team selection process. As always, a team with a shared vision for the care they provide as well as a supportive and incentivized environment are integral for the success of the virtual-care mechanism.

» Future studies should assess the impact of primarily virtual, integrated, and multidisciplinary team-based approaches and systems of care on patient outcomes, health-care expenditure, and patient satisfaction in the orthopaedic population.
Keywords-Driven Paper Recommendation Based on Undirected Paper Citation Graph
Authors: Liu Hanwen
Published: July 2021

Nowadays, recommender systems have become one of the main tools and methods for users to search for their interested papers from massive candidates. Considering the above drawbacks, in this paper, we propose a link prediction approach that combines time, keywords and authors information for constructing a new relation graph. Finally, a case study is employed to explain our approach step by step and demonstrate the feasibility of our proposal.

Published: July 2021

Achieving low-carbon energy transformation is vital for coordinating economic growth and environmental improvement to satisfy the carbon emissions peak and carbon neutrality targets. Existing studies, however, have been dominated by the mere exploration of the low-carbon transformation pathway with little consideration of the importance of energy substitution in low-carbon transformation. Doing so is believably unable to gain the double dividend effect for the economy and environment. Accordingly, this paper develops three energy-target scenarios, taking into account energy structure, electrification level, and carbon mitigation targets by 2030 announced by the Chinese government. A dynamic multi-sectoral computable general equilibrium model, CHINAGEM, is employed to examine the economic and environmental effects under different pathways of long-term low-carbon transformation. Firstly, we detect that China's primary energy consumption and electricity production structure would substantially transfer to low-carbon and clean along with all three energy-target scenarios. Secondly, due to the anticipated decline of fossil energy consumption, especially coal consumption, China's CO2, SO2, and NOX emissions in 2020-2030 would also possibly vastly abate with all the scenarios. Besides, it is highly conceivable for China to achieve its peak carbon emission of 12.4 GtCO2 in 2028 if it serves the comparatively more stringent low-carbon transformation pathways. Lastly, different pathways would also produce varying positive impacts on China's macro-economy and achieve the different extent of double dividend effects. The research concludes with a recommendation of tentative improvement policies towards low-carbon transformation under the carbon peak and carbon neutrality goals, including promoting energy substitution, renewable energy development, and low-carbon technologies.

PurposeTo evaluate the effects of discontinuing anticoagulants(ACs)/antiplatelets(APs) preoperatively on surgery for blepharoptosisMethodA retrospective analysis included patients with acquired blepharoptosis who underwent surgical correction, and were followed for more than one month. Patients were classified into two groups depending on AC/AP treatment or otherwise. All patients taking AC/AP discontinued with the treatment one week prior to surgery in accordance with our clinical guidelines. Preoperative and postoperative marginal reflex distance 1(MRD1) and ecchymosis grade were evaluated and compared.ResultsGroup 1 (AC/AP treatment cessation) included 47 patients with 93 eyelids, and group 2 (control) included 51 patients with 98 eyelids. The preoperative MRD1 showed no significant difference between groups. Group 1 showed a significantly higher rate of severe ecchymosis (41.8 vs. 22.4%, p = 0.004) at 1 week of surgery as well as 'persistent ecchymosis (58.8 vs. 7.3%, p=0.000) compared with group 2 postoperatively at 1 month. Postoperative MRD1 was significantly lower in group 1 at 1 week (p=0.019). However, the MRD1 and degree of improvement in lid height (postoperative MRD1–preoperative MRD1) was not significantly different between the two groups (p = 0.499, p = 0.058) at 1 month postoperatively.ConclusionPostoperative ecchymosis was more severe in group 1 at one month after ptosis surgery even though the ACs/APs were discontinued. Surgeons should be careful about this before operation.

Published: July 2021

Controlled fire use by hunter-gatherers and smallholder agriculturalists and pastoralists shapes ecologies and enhances livelihoods worldwide. Yet, at the global scale, we know little about how these practices influence human wellbeing, ecologies, and wildfire risk. As a basis for global syntheses, we collated information from the literature about fire practices in 587 case study locations spanning the globe. Here, we assess the coverage and completeness of this data. Limited quantitative data, particularly, presents a challenge for improved modelling of anthropogenic influences on fire regimes. We also analyse global trends in fire practices from these studies, finding evidence that subsistence-oriented fire practices have declined in recent decades, while market-oriented fire practices have increased. The case studies point to important drivers of these changes, especially economic pressures, and state governance. We discuss the implications of these findings for fire policy, and future research.

This paper presents a numerically simulated Ge-source based Tunnel Field Effect Transistor with (TFETs) SiO 2 segregation between the channel and drain. The developed device has been compared with conventional TFET and without isolated heterojunction TFET. The use of oxide segregation between channel and drain enhances the performance of the device in terms of ON-state current as well as subthreshold swing (SS). The electrical characteristics such as surface potential, electric field, transfer characteristics, output characteristics of the proposed device have been studied. The temperature variation of the proposed device has also been studied. The proposed device offers high ON current of 3x10 4 A, I ON /I OFF ratio of ~10 11, and enhanced SS of 30 mV/dec. The validity of the proposed device has been done by Synopsys Sentaurus TCAD.

Published: July 2021

Docosahexaenoic acid (DHA) is an essential fatty acid necessary for brain development in both infants and adults. However, the role of gut microbiome and their metabolites produced from DHA remain unclear. In present study, the bacterial isolates Lactobacillus spp. Clostridium spp. Escherichia coli; Staphylococcus spp. Enterococcus spp. were used to convert the metabolites from DHA with SM medium supplemented with 200mg of DHA as substrate. The metabolites were extracted after 24 hours of incubation at 37°C and analyzed by GC/MS. The antimicrobial activity of these metabolites confirmed their effectiveness against clinical pathogens such as Bacillus cereus, Escherichia coli, Pseudomonas aeruginosa, Salmonella enteritidis and Staphylococcus aureus.

Aims Rehabilitation of submerged vegetation is one of the commonly used techniques for the ecological restoration of shallow lakes. The changes of pollution structure in sediments caused by plant recovery and the rhizosphere chemical process under different sediment organic matter (SOM) levels are theoretical basis for the rational application of plant rehabilitation technology in lake management.Methods A circulating extraction system was designed for in situ collection of rhizospheric metabolites especially for the submerged plants. We explored how Vallisneria natans (V. natans) mediate the changes in sediment N and P through rhizospheric metabolites under low (4.94%) and high (17.35%) SOM levels. Results By analysing 63 rhizospheric metabolites from V. natans, glucitol was found to be 146.82% lower in the low SOM than in the high SOM treatment. NH4-N and NO2-N increased by 57% and 68.39%, respectively, in the high SOM treatment, while approximately one-seventh Inorg-P was transferred from Fe/Al-P to Ca-P in the low SOM treatment. The metabolites lactic acid, 3-hydroxybutyric acid, and phosphoric acid mediated NH4-N accumulation. Additionally, 3-hydroxy-decanoic acid and adipic acid mediated the transformation of Fe/Al-P to Ca-P.Conclusions The growth of V. natans significantly changed Inorg-N or Inorg-P fractions. The changes were SOM level-dependent and rhizosphere metabolites related. This study emphasised the benefit of V. natans rehabilitation at low SOM level. When restoring submerged macrophytes from high SOM sediment, care should be taken due to the release potential of labile N and P forms.

Background: Childhood tuberculosis (TB) remains a major public health problem in Uganda. Failure to complete TB treatment is associated with development of multi-drug-resistant TB, continued spread of TB, and death. The World Health Organization (WHO) recommends treatment success rates of ≥85% to achieve TB control, but children often have lower success rates due to challenges in case identification and treatment adherence. We assessed trends in childhood TB case notification rates, spatial case distribution, treatment outcomes, and predictors of treatment completion at Mbale Regional Referral Hospital (MRRH) in Eastern Uganda.Methods: We reviewed TB registers and extracted data for patients aged 0-14 years with presumptive TB at MRRH for 2013-2017. We determined the childhood TB case notification rate in the MRRH catchment area, performed a TB case notification rate trend analysis and described spatial TB case distribution. We used logistic regression to identify patient-related and hospital-related factors associated with completion of TB treatment at MRRH among HIV-positive and HIV-negative patients. Results: We identified 331 TB case notifications among children <15 years. TB case notification rates declined from 6.6/100,000 in 2013 to 2.2/100,000 in 2017 [odds ratio (OR)=0.81; 95% confidence intervals (CI)=0.58-1.1]. Mbale District recorded the highest TB case notification rate (79/100,000), and Kapchorwa District recorded the lowest TB case notification rate (3.8/100,000). Completion rates varied from 35% to 80%. Of the 331 patients, 167 (50%) completed TB treatment. In logistic regression, 142 (75%) of 189 HIV-negative TB patients completed TB treatment compared to 25 (54%) of 46 HIV-positive TB patients (OR=2.5; 95%CI=1.3-4.9). Seventy-four (63%) of 117 patients in the facility-based model and 93 (79%) of patients in the community-based model completed TB treatment (OR=0.47; 95% CI=0.26-0.83).Conclusions: Only half of childhood TB patients completed treatment, well below the WHO target of ≥85% completion. Although TB completion was associated with treatment model and HIV-negative status, neither HIV-positive nor HIV-negative patients had acceptable completion rates. MRRH should strengthen HIV treatment services among childhood TB patients by engaging peer groups and trusted community leaders to provide education on the importance of completing TB treatment.
