Buku kajian dan advokasi ini adalah untuk mengingatkan kembali bahwa semangat klausul Memorandum of Understanding (MoU) Helsinki yang tertuang dalam Undang-Undang Pemerintahan Aceh (UUPA), Undang-Undang Nomor 11 tahun 2006 terkesan diterjemahkan tidak sesuai kepentingan dan harapan rakyat Aceh. Sejak penandatanganan MoU Helsinki pada 15 Agustus 2005 yang telah berusia hampir 15 tahun lamanya, kondisi Aceh tidak memperlihatkan kemajuan yang signifikan. Aceh dihadapkan pada fakta keterpurukan ekonomi dengan lemahnya daya beli masyarakat, sulitnya mencari pekerjaan, dan tingginya angka kemiskinan hingga Aceh masuk dalam kategori provinsi termiskin di Sumatera. Sungguh miris! Kondisi di Aceh bertentangan dengan dasar-dasar berpikir logika hingga mengherankan masyarakat dunia. Bagaimana bisa, dengan limpahan dana otonomi khusus yang mencapai puluhan triliun tapi rakyatnya miskin (pernah disampaikan Dr. Syurkani Ishak Kasim, Direktur Eksekutif Asian Development Bank). Membicarakan kembali MoU Helsinki dan UUPA berarti merekonstruksi kembali, menyambung kembali ingatan akan identitas Aceh dengan keistimewaannya yang sempat lupa atau dilupakan oleh kekuasaan atau kesengajaan struktural. Apa yang dialami Aceh saat ini bukan semata kesalahan Aceh tapi juga karena ketidaktulusan negara untuk bersama-sama mengimplementasikan MoU Helsinki secara berkeadilan dan komprehensif. Maka apabila orang bertanya kepada saya, apakah keadilan atau pemerataan pembangunan yang harus didahulukan bagi pembangunan Aceh? Maka saya akan jawab, “Keadilan! Hak atas keadilan untuk Aceh yang tertuang dalam MoU Helsinki!” Aceh butuh keadilan memori sebagai wujud keadilan negara pada bangsanya.

The Anti-inflammatory effect of Onion extract in rabbit with Corneal ulcer
Authors: Komariah Cicih , Salsabila Rana , Hilda Hapsari Asyifa , Rizky Kurnia Putri Sixma , Febianti Zahrah
Published: May 2021

Corneal ulcer is a pathological condition of the cornea characterized by corneal tissue discontinuity on stromal epithelium. The most common cause of corneal ulcers is due to Staphylococcus bacterial infection. Staphylococcus aureus infects the cornea by secreting alpha-toxin and protease, which degrade the corneal extracellular matrix. Neutrophils, as an innate immune system, will be involved in bacterial phagocytosis. If the corneal ulcer is not treated properly, it will become scar with neovascularization, which cause partial or total blindness. Onion (Allium cepa L.) contains quercetin, which has antibacterial properties and is thought to inhibit the angiogenic mediator, namely Vascular Endothelial Growth Factor (VEGF). This study aimed to determine the effect and minimum effective concentration of onion extract administration, which can decrease the neutrophils, scar area, and neovascularization number in corneal ulcer rabbit induced with Staphylococcus aureus. This study is true experimental research with a post-test only control group design. Corneal ulcers in rabbits are made by intra-stromal injection of the Staphylococcus aureus. After the corneal ulcer formed, each group received one of the following treatments: moxifloxacin HCl 0.5%, onion extract 1.5%; 3%; 6%; and 12% for 7 days. The results showed that onion extract (Allium cepa L.) could decrease neutrophil count at a concentration of 6.5% and inhibit the formation of neovascularization at a concentration of 3%.
Natural Occurring Radioactive Materials (NORM) in the oil and gas industry
Authors: Zaidan Jamal  Abdul Rahman
Published: May 2021

Radioactive materials which occur naturally and expose people to radiation occur widely, and are known by the acronym 'NORM'. Exposure to NORM is often increased by human activities, eg burning coal, making and using fertilisers, oil and gas production.

Many natural materials contain radioactive elements (radionuclides). The earth's crust is radioactive and constantly leaks radon gas into our atmosphere. However, while the level of individual exposure from all this is usually trivial, some issues arise regarding regulation, and also perspective in relation to what is classified as radioactive waste.The radionuclides identified in oil and gas streams belong to the decay chains of the naturally occurring primordial radionuclides 238U and 232Th. Analyses of NORM from many different oil and gas fields show that the solids found in the downhole and surface structures of oil and gas production facilities do not include 238U and 232Th. gas

These elements are not mobilized from the reservoir rock that contains the oil, gas and formation water.

Formation water contains the radium isotopes 226Ra from the 238U series, and 228Ra and 224Ra from the 232Th series. All three radium isotopes, but not their parents, thus appear in the water co-produced with the oil or gas. The 228Th radionuclide sometimes detected in aged sludge. This causes their precipitation as sulphate and carbonate scales. The mixed stream of oil, and water also carries the noble gas 222Rn that is generated in the reservoir rock through decay of 226Ra. It would appear that the concentrations of 226Ra, 228Ra and 224Ra in scales and sludge range from less than 0.1 Bq/g up to 15 000 Bq/g. Generally,

 the activity concentrations of radium isotopes are lower in sludge than in scales, the opposite applies to 210Pb. The deposition of contaminated scales and sludge in pipes and vessels may produce significant dose rates inside and outside these components. Maximum dose rates are usually in the range of up to a few microsieverts per hour. In exceptional cases, dose rates measured directly on the outside surfaces of production equipment have reached several hundred microsieverts per hour, which is about 1000 times greater than normal background values due to cosmic radiation and terrestrial radiation.

Phase Change Materials for Thermal Energy Storage
Authors: AL-Ataby Mohammed Jafer Ali
Published: May 2021

Salt hydrate phase change materials used for thermal storage in space heating and cooling applications have low material costs, but high packaging costs. A more economic installed storage may be possible with medium priced, high latent heat. Latent heat storage is one of the most efficient ways of storing thermal energy. Unlike the sensible heat storage method, the latent heat storage method provides much higher storage density, with a smaller temperature difference between storing and releasing heat. This paper work on latent heat storage and provides an insight to recent efforts to develop new classes of phase change materials (PCMs) for

use in energy storage. There are large numbers of phase change materials that melt and solidify at a wide range of temperatures, making them attractive in a number of applications. Hydrated salts have larger energy storage density and higher thermal conductivity but experience super cooling and phase segregation, and hence, their application requires the use of some nucleating and thickening agents. Sodium carb-onate, sodium phosphate and sodium sulfate tested as phase change material by crystallization in this work.

Published: May 2021

An unprepared drilling team or an inexperienced group in dealing with bottom hole drilling problemscan cause serious injury, health troubles, environmental damage and rigorous financial losses for anycontingency hole troubles that might be faced during the drilling progress. For that reason, drillingsimulators have been developed and used in teaching and training, usually in well control, focusing onhow to handle the most dangerous and expensive problems such as kicks, mud losses, and stuck pipes.It is believed that the practice preferred to be related to real cases for best results, so modern techniqueshave been introduced in this research to build anew drilling simulator software under the name “Kick-Sim100”. The main programming language used is C# language and Unity3D editor used as a programming environment, together used to connect, exhibit and implement field experiences and fielddata that gathered and analyzed from southern Iraqi fields.Kick-Sim100 imitates the behavior of the kick for both types: gas and water kick. It also mimics two ofthe most common well control methods, namely the “Driller” method and the “wait and weight”method. This simulator deals with southern Iraqi formations also manages the possibilities of kickoccurrence and problems solving steps by involving all the potential odds that might arise during wellkilling procedures automatically, in which It does not need any instructor involvement.Kick-Sim100 is expected to have a great impact on the improvement of the drilling staff abilities inhandling kick detection while drilling and well-killing methods. It is also planned to participate in Iraqipetroleum engineering educational systems in the future if developed.

Authors: A.Razzaq Ayad A.Alhaleem , Neamah Hasan Ali
Published: May 2021

The benefits from doing this analytical study in order to be able to measure and predict the frictional forces affecting a drill string and wellbore (Torque and drag) by construct model of well plan software, hence; the high deviated and directional wells must be planned to keep the torque and drag forces at a minimum and allowable limit.

Also, knowledge of the drill string phenomena can give us an opportunity to choose drill string components that consider these extra forces involved in the operations "high torque and drag values" in directional sections.

In addition to knowledge of influence torque and drag on planned well trajectory can give us a good idea and lesson learned to consider this challenges in the next planned well profile. As a result of well path design one of the best ways to reduce torque and drag forces.

One deviated well in Zubair oil field named, ZB-348 have been selected for analyses torque and drag problems and study the effect of (friction factor, well profile and drill string design) on the mentioned problem.

Well data include hole section size, fluid properties, well profile survey, rig specification, drill string details and drilling parameters were used in well plan software from landmark worldwide programming group to make a comparison between actual and planning status.

The results show a difference between planning and actual case when drilling 12.25" hole and found the root causes for this difference are high flow rate, tortuosity, well bore instability and complete losses. 

The maximum torque about (20 klb-ft) and drag value approximately (30 klb).

Objective: To evaluate the incidence and the correlation between the risk factors of ureteric injury and complications in patients who underwent prophylactic ureteric catheterization before pelvic surgeries.

Material and Method: From October 2015 to December 2018, the medical records of 130 patients in Rajavithi Hospital who underwent pelvic surgeries and prophylactic ureteric catheterization were retrospectively reviewed. Information included age, history of previous pelvic surgeries, pelvic radiation, presence of hydronephrosis, pathology, stage of cancer, injury of ureters, and complications.

Results: Incidence of ureteric injury was 4.6% (n=6). The significant risk of injury was location of the tumor at the ovary (p=0.034); borderline significant risk was malignant pathology (p=0.057). After the procedure, 16.2% (n=21) of the patients had gross hematuria and 14.6% (n=19) of the patients had a urinary tract infection. Average time of catheterization was 20.95 minutes. Significant risk of gross hematuria was older age (p<0.001) and malignant pathology (p=0.006).

Conclusion: From this study, ureteric injury may be significantly higher in cases of malignancy at the ovary and may not prevent injury in high-risk patients. Ureteric catheterization should be carefully considered in elderly patients because of the higher rate of complications.
Correlation evaluation of the international prostate symptom score (IPSS), visual prostate symptom score (VPSS), and modified visual prostate symptom score (mVPSS) in Thai males with benign prostatic hyperplasia

Published: May 2021

Objective: To study the correlation between the modified visual prostate symptom score (mVPSS), the visual prostate symptom score (VPSS) and the international prostate symptom score (IPSS) in Thai males who were diagnosed with benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS).

Material and Method: One hundred and ten Thai males who were diagnosed with BPH and LUTS by urologists were enrolled onto the study between 1st March and 31st July 2019. They were divided into 2 different groups by simple random sampling. The first group was requested to complete the A questionnaire which was composed of IPSS and VPSS and the second group was assigned to finish the B questionnaire which consisted of IPSS and mVPSS. Both groups had to complete their personal data, including age, education level, monthly income, and duration of treatment for BPH, and they also were classified as high or low educated groups. The correlations between the scores of mVPSS, VPSS, and IPSS in the high or low educated groups were assessed using Pearson’s correlation coefficient with IBM SPSS statistics 22.0.

Results: There were statistically significant correlations between mVPSS, VPSS, and IPSS (P<0.05) in total and individual scores, which consisted of quality of life, voiding symptom score, storage symptom score, frequency score and nocturia score. According to this study, it was found that the mVPSS and VPSS questionnaires took less time to complete and were easier than the IPSS. However, in high-educated patients, there was no statistically significant rate to complete the mVPSS, VPSS and IPSS questionnaire by themselves. In addition, this study showed a strong positive correlation between the IPSS versus mVPSS and VPSS in the high-educated groups (r=0.935 and r=0.898, respectively). In contrast, in the low-educated patient group, there was no statistically significant correlation between the VPSS and IPSS questionnaires in frequency score. However, this study found a positive correlation of frequency score between the mVPSS and IPSS questionnaires in all educated groups. Moreover, most patients felt that the mVPSS and VPSS questionnaires were easier to understand and complete than the IPSS questionnaire.

Conclusion: The mVPSS shows a statistically significant correlation to the IPSS standard questionnaire, which means that the IPSS can be replaced by the mVPSS in order to evaluate Thai males with BPH and LUTS, because the mVPSS can be used with all educated groups and the patients are able to understand and complete the questionnaire more quickly. For these reasons, the mVPSS is an excellent choice to replace the VPSS and IPSS, which still have many limitations with varieties of patients.

Objective: To review the presentation, predisposing factors, treatment and outcome of renal vascular malformation, including arteriovenous malformation (AVM), arteriovenous fistula (AVF) and pseudoaneurysm of the kidney in Ramathibodi Hospital.

Material and Method: In-patient medical records from January 2007 to January 2017 were retrospectively reviewed. Patients admitted and diagnosed with any type of vascular malformation of the kidney, comprising AVM, AVF and pseudoaneurysm in Ramathibodi Hospital were included in the study. Baseline characteristics of the patients, including gender, age at diagnosis, and underlying disease were recorded. Vascular malformation, clinical presentation, imaging data, predisposing factors of the disease, treatment and the outcome of patients were summarized and reported.

Results: Seventeen patients were diagnosed with vascular malformation; 9 patients were males and 8 females. The most common comorbidity was hypertension, followed by chronic kidney disease.
Nine patients had AVF (52.94%), 3 had AVM (17.65%), 2 had pseudoaneurysm (11.76%), and 3 had AVF with pseudoaneurysm (17.65%). Common presentations were gross hematuria, flank pain, anemia, and hypovolemic shock. Previous surgery and history of renal biopsy were mutual predisposing factors. Embolization was the most common treatment option. All patients were asymptomatic on follow-up visit with a median follow-up of 90 days.

Conclusion: Vascular malformation of the kidney is not a common condition. The history of previous kidney surgery and renal biopsy may help for diagnostic suspicion. Renal embolization was the proper management with a high success rate.

Objective: The aim of this study was to compare the postoperative outcomes of patients receiving standard percutaneous nephrolithotomy (S-PCNL) and modified mini percutaneous nephrolithotomy (MM-PCNL) in Yala Hospital.

Material and Method: We collected data from 117 patients who underwent S-PCNL or MM-PCNL from 2013-2018. We compared the data of patient characteristics, laboratory results, and postoperative outcomes, such as operative times, duration of catheter, blood transfusion rate, duration of hospitalization, stone free rate and complication rate between the S-PCNL and MM-PCNL groups.

Results: There were no significant differences in operative time, blood transfusion rate, stone free rate and complication rate between the 2 groups. However, the duration of catheter and hospitalization in the MM-PCNL group was significantly shorter than in the S-PCNL group.

Conclusion: Hence, we confirmed that MM-PCNL could be used as an alternative procedure to Mini-PCNL for the management of renal stones in other tertiary hospitals which already have the equipment for S-PCNL by modifying that equipment, as we have shown.
What conditions tone paradigms in Yukuna: Phonological and machine learning approaches
Authors: Lemus-Serrano Magdalena , Allassonnière-Tang Marc , Dediu Dan
Published: May 2021

Yukuna is an understudied Arawak language of North-West Amazonia with a privative tonal system. In this system, roots are underlyingly specified for tone, whilst affixes are toneless. However, affixation interacts with tone, leading to many variations in surface tonal patterns. This paper puts forth a qualitative analysis of Yukuna’s tonal system, and provides data-driven evidence in favor of this analysis using machine learning methods. More precisely, we use decision trees and random forests to assess quantitatively the predictions of the phonological analysis. A manually annotated corpus of verbal paradigms was split into a training and a testing set. We trained the computational classifiers on the first and tested their predictions on the second. We found that they predict the majority of the patterns and support the qualitative analysis. Additionally, they suggest avenues for enhancing the phonological analysis, by providing a ranking of the variables that highlight statistical tendencies within tonal patterns. Besides its contribution to understanding tonal systems in general and of that of Yukuna in particular, our work also suggests that such machine learning approaches might become part of the complex theoretical and methodological toolkit needed for language description and linguistic theory development.

Os Ambientes Virtuais de Aprendizagem (AVA) estão cada vez mais presentes nas instituições de ensino, visto que consistem em mais um recurso para melhorar a comunicação entre alunos e professores. Embora esses sistemas não sejam novos, poucos estudos têm avaliado a performance e o consumo de energia dos mesmos. Avaliar a relação entre a performance e o consumo de energia dos AVAs é essencial para solucionar questões tanto na fase de implementação de um novo projeto quanto na ampliação ou atualização da infraestrutura já existente. Portanto, este trabalho visa avaliar o desempenho e o consumo de energia do ambiente MOODLE, plataforma que fornece suporte a AVAs, utilizando dois sistemas de nuvens privadas, o Apache CloudStack e OpenStack. Uma metodologia é proposta para proporcionar a realização de tais experimentos através de medições. Um estudo de caso foi realizado para ilustrar a aplicabilidade da metodologia em um ambiente real com o Moodle configurado tanto no Apache CloudStack quanto no OpenStack. Os resultados revelaram que o desempenho e também o consumo de energia são diferentes entre os dois sistemas. Por exemplo, nos experimentos realizados, o OpenStack apresentou um maior consumo de energia quando comparando ao Apache CloudStack por demandar um maior tempo de resposta.
In Situ Multiple Sulfur Isotope and S/Se Composition of Magmatic Sulfide Occurrences in the Labrador Trough, Northern Quebec

Published: May 2021

The interaction between mafic-ultramafic magma and crustal sulfide is considered a key process in the formation of magmatic Ni-Cu-platinum group element (PGE) sulfide deposits. Integrated S/Se and multiple sulfur isotope studies are the most robust in constraining the role of crustal sulfur during ore genesis. In the present study, we report the first integrated S/Se and multiple sulfur isotope study of magmatic sulfide occurrences in the Labrador Trough, namely, on the recently discovered Idefix PGE-Cu and Huckleberry Cu-Ni-(PGE) prospects.

Whole-rock and in situ S/Se values (~810–3115) of magmatic sulfides and their host rocks are consistent with S loss during postmagmatic hydrothermal alteration, negating their use in interpreting the origin of S. Values of ∆33S ~0 indicate no record of the assimilation of Archaean sulfur. Disseminated (–0.5 to +2.5‰) and globular (3.0–4.5‰) sulfides at Idefix as well as globular sulfides (2.1–9.6‰) at Huckleberry have δ34S values greater than the accepted mantle range, suggesting that crustal S played a role in the formation of these sulfides. In contrast, disseminated and net-textured sulfides at Huckleberry have variable δ34S values (–4.6 to +3.2‰) that are mostly within the accepted mantle range, excluding one anomalous sample that records relatively higher δ34S values (11.9–15.0‰). It is proposed that sulfide melt segregated in response to the addition of small proportions of crustal S prior to the final emplacement of the host intrusions, i.e., in a feeder conduit or staging chamber. Isotopic exchange between the sulfide melt and silicate magma has diluted and, in places, eradicated a crustal δ34S signature.
Worldwide Introduction of North American Pawpaw (Asimina triloba): Evidence Based on Scientific Reports
Authors: Brannan Robert G. , Coyle Maria N.
Published: May 2021

The North American pawpaw (Asimina triloba) is a small tree native to the Appalachian region of the United States that produces large, yellowish-green to brown fruit that has the flavor of a banana and mango. The scope of this review is limited to pawpaw orchards outside of North America that were intentionally planted for commercial or research purposes and are documented in the scientific literature. This review identified nine countries outside of North America (Romania, Italy, Ukraine, Slovakia, Austria, Georgia, Russia, Japan, Korea) and across two continents that have scientific literature that describes pawpaw cultivation. There are reports that pawpaws are cultivated in China, Israel, Belgium, and Portugal, however, no scientific literature could be found that describes pawpaw research from these countries. Most of the research since 2010 has featured pawpaws grown in Romania, Italy, and Korea with a focus on characterizing roots, twigs, leaves, pulp and seeds or the toxicity and/or bioactivity of the annonaceous acetogenins naturally found in these parts of the pawpaw.
HIL Evaluation of a Novel Real-time Energy Management System for an HEV with a Continuously Variable Transmission
Authors: Taghavipour Amir , Alipour Ali
Published: May 2021

One of the most important challenges facing automotive engineers is reducing vehicle fuel consumption and improving the drivability index. Modern hybrid electric powertrains play an important role in reducing fuel consumption. Continuously variable transmission (CVT) is an automatic transmission that can change the gear ratio seamlessly using a belt and pulleys. CVT performs with infinite gear ratios. Controlling and determining the optimal gear ratio, especially in a complex hybrid powertrain, is a major challenge. Therefore, a multi-parametric model predictive controller with real-time implementation capability is proposed that can handle the energy management task concurrently with gear shifting strategy in a parallel pre-transmission hybrid electric vehicle. The proposed controller hardware-in-the-loop (HIL) validation procedure on the high-fidelity Autonomie model shows significant improvement in fuel economy while maintaining drivability in three different driving schedules. HIL evaluation guarantees the real-time capability and the proposed controller readiness to be implemented to real-world control hardware.
Territorio y redes alimentarias alternativas: experiencias en la ciudad de Sevilla
Authors: González-Romero Gema , Cánovas-García Fulgencio
Published: May 2021

Las redes alimentarias alternativas son un fenómeno de marcado carácter urbano con una expansión significativa durante las primeras décadas del siglo XXI. Se vinculan a movimientos ciudadanos en respuesta a los impactos socioeconómicos, ambientales y territoriales de un régimen alimentario globalizado y financiarizado, así como a la creciente preocupación por la seguridad y la calidad alimentarias. El objetivo de este artículo es analizar dichas redes en Sevilla, prestando especial atención a sus implicaciones territoriales, aspecto poco tratado hasta ahora en la literatura que aborda esta temática. Se ha aplicado una metodología mixta: cualitativa (entrevistas semiestructuradas y observación virtual) y cuantitativa (bases de datos y redes sociales). En Sevilla, las iniciativas vinculadas a redes alimentarias alternativas están arraigadas en determinados barrios y sus implicaciones territoriales sobrepasan el ámbito periurbano. Pese a sus limitaciones, no puede dejar de valorarse su capacidad para generar proyectos colectivos en favor de un sistema alimentario más justo y sostenible.
Panorama da saúde bucal na atenção básica nas macrorregiões brasileiras no período de 2009 a 2018

Published: May 2021

Este estudo analisou o panorama da saúde bucal na Atenção Básica no período de 2009 a 2018 nas macrorregiões brasileiras. Para isto foram utilizados os indicadores de cobertura populacional de equipes de saúde bucal, Primeira Consulta Odontológica Programática e Ação Coletiva de Escovação Dental Supervisionada; também foram analisados os repasses federais para saúde bucal na Atenção Básica para estados e municípios. Embora a cobertura populacional por equipes de saúde bucal tenha se mantido em contínuo crescimento, a partir do ano de 2015 houve expressiva queda no desempenho dos outros indicadores analisados. O montante de recursos federais destinados ao financiamento tripartite das ações de saúde bucal para estados e municípios sofreu forte impacto após aprovação da Emenda Constitucional nº 95 em 15/12/16, principalmente no ano de 2018, afetado também pela mudança nos blocos de financiamento dada pela Portaria nº 3992 de 28/12/17. Após a segunda década do Sistema Único de Saúde (de 1999 a 2008) ter sido de expansão da saúde bucal com direcionamento e criação de políticas públicas para esta área, esperava-se que a década seguinte, de 2009 a 2018, fosse um período de consolidação. No entanto, o que se constata na presente análise é o desmonte das políticas públicas e fragilização da área de saúde bucal.

Published: May 2021

Background
Posterior component separation (PCS) via transversus abdominis release (TAR) technique overcomes the pitfalls of traditionally described repairs. We evaluate the safety and efficacy of this approach and present the lessons we have learnt in our experience with a large series of complex ventral hernias. We also evaluate the importance of pre-operative optimisation and the value of a dedicated abdominal wall reconstruction (AWR) team in improving the surgical outcomes.

Study Design
A retrospective review of all patients undergoing TAR at a specialised hernia centre in the 2016-2019 period was performed. Pertinent data collected included patient demographics, peri-operative details and post-operative complications. Primary outcome variables were surgical site occurrences (SSO) and hernia recurrence. A multivariate regression model was developed to determine significant predictors of SSO.

Results
In 92 consecutive patients, the mean age was 52 years with a mean body mass index of 27.9%. Major comorbidities included diabetes (41%), hypertension (23%), and chronic obstructive pulmonary disease (15%). The mean hernia defect was 13.2 cm and the average operative time was 232 minutes. Complete posterior sheath closure was achieved in 95.6% cases. There were 18 (19.5%) cases of SSO which were managed conservatively and no cases required mesh explanation. There were 2 (2.1%) recurrences which required a redo surgery. On multivariate analysis operative time (p value 0.047) was a significant predictor of SSO.

Conclusions
AWR using the TAR approach offers a robust repair with low overall morbidity. A holistic pre-operative optimisation strategy and a dedicated AWR team can further improve surgical outcomes.
