Risk factors and skin colonization/recolonization – a matter in the development of sternal wound infection after cardiac surgery
Authors: Koziol Malgorzata Maria , Czepinska Aleksandra , Stazka Janusz
Published: September 2024

Cardiac surgeries are classified as “clean procedures” as they do not involve access to any space populated by the patient’s microbiota. Nevertheless, the development of sternal wound infection (SWI) can sometimes occur. The aim of the study was to analyze risk factors of SWI, efficacy of antiseptics procedures, skin microbiota colonization/recolonization, and their impact on infection development in patients undergoing cardiac surgery.

Of 500 patients who had undergone cardiac surgery through a median sternotomy, perioperative swabs of standardized surgical cut area were taken at three-time points: ‘1’-after admission to treatment rooms, ‘2’-before incision; ‘3’-before chest reconstruction. Material was cultured and grown bacterial colonies were counted.

Out of the total population, 23 patients developed SWI and 11 had suspicion of SWI while 466 were without SWI. Risk factors which had statistically significant impact of infection development were high body mass index (BMI) and use of cardiopulmonary bypass (CPB) during operation. The most common SWI-pathogens were coagulase-negative staphylococci (CoNS) and Gram-negative bacilli. From the perioperative period, CoNS and Staphylococcus aureus were isolated. When simultaneous positive cultures in ‘swab-1 and -3’ were observed (respectively, ≥87 and ≥17 bacterial colonies), the risk of complications was higher (patients with SWI – 69.57%; without SWI – 6.71%). Regarding point ‘3’, significant differences were noted in the general level of grown colonies. About 3 times more bacterial colonies were grown in the group with healing problems and SWI. SWI development is multifactorial. The rate of skin microbiota recolonization during surgery may suggests that being more colonized in the surgical incision area was more susceptible to local complications.
Molecular alterations in mucinous ovarian tumors – a review
Authors: Kawecka Weronika , Bielak Michal , Urbanska Karolina
Published: September 2024

Mucinous ovarian tumors (MOTs) include primary and secondary neoplasms, the latter of which contribute for 80% of all cases. The most common site of origin for secondary MOTs is the gastrointestinal tract. Proper differentiation between primary and metastatic lesions is essential for effective treatment. Currently, definitive diagnosis is made based on post-operative histopathological examination with the use of immunohistochemical markers. However, the final diagnosis presents a challenge because of the histopathological similarity between mucinous metastases and primary ovarian lesions. Generally, treatment consists of cytoreductive surgery and adjuvant chemotherapy, even though malignant tumors are found to be chemo-resistant. Prognosis depends on the type of the tumor, presence of metastases and patient’s general condition. Further research on the genetic background of MOTs is necessary for the better understanding of their origin and more effective treatment. This review aims to summarize recent advances in the field of the molecular features of MOTs and their implications for the diagnostic pathways and potential adjuvant therapy options. The analysis of molecular alterations might not only be an important prognostic factor, but also a useful diagnostic tool in distinguishing between primary mucinous tumors and extra-ovarian metastases or other subtypes of epithelial ovarian neoplasms. Moreover, the examination of genetic mutations seems to increase the efficiency of targeted therapy. However, more research evaluating such therapies in pre-clinical models is needed to improve the results of the diagnostics and treatment of MOTs.

Cities on the Edge, Cities of Enchantment: Invisible Cities in the Far North
Authors: Egeler Matthias , Jónsdóttir Dagrún Ósk
Published: September 2024

Calvino’s Invisible Cities tells a multitude of stories of invisible, unreal, utopian and anti-utopian cities and explores ‘the hidden reasons which bring men to live in cities: reasons which remain valid over and above any crisis’. Our contribution takes up some of the themes that Calvino places at the heart of his poetic meditation on city life. This includes his praise of magical enchantment; the desire for human company that pervades his meditations on the desert traveller’s – the solitary individual’s – view of the city; and the fundamental role of the human action that is most central to Calvino’s book, namely, storytelling itself. To pursue these themes, we take the reader on a journey to some of the northernmost inhabited parts of Iceland, where habitation itself is crumbling.
Daughters and Inheritance: Babylonian Boundary Stone 9 and Numbers 27
Authors: Campbell Nicholas J.
Published: September 2024

A daughter’s ability to inherit property is treated differently in various ancient Near Eastern cultures. This paper examines the difference between land inheritance by daughters in Israel and Babylon using the text of Numbers 27 and Babylonian Boundary Stone 9. The unique status of land and land allotment in the two societies are explored as well as the implications for the status of daughters. The conclusion from the comparison is that the biblical text excludes daughters because of limited landholdings and the desire to maintain the property inheritance from the initial land allotment event. However, Babylonian Boundary Stone 9 allows daughters to inherit more easily because of fluid landholdings and multiple (royal) land allotment events.

This article aims to offers the topic of Onesimus as Philemon’s brother in Paul’s letter to Philemon as a solution to conflict the religiousness between Christianity and Islam. The approach of this article is a postcolonial perspective, where building change from society tends to be positioned on the “two poles” or binary into a society that integrates with each other and rubs off between communities that are local, communal, and global simultaneously.
The Controversy Name of Boaz in the Bible Genealogy from Matthean Perspective: Intertextuality Approach
Authors: Chia Philip Suciadi
Published: September 2024

The appearance of Boaz’s name in the Bible genealogy – Ruth, 1 Chronicles, Matthew, and Luke – creates difficulty. Ruth 4:21, 1 Chronicles 2:12, Matthew 1:5, Luke 3:32 informs that Boaz was the father of Obed. The issue is the Bible, both Old Testament and New Testament, mentions that the father of Obed should be Mahlon, and not Boaz. According to the book of Deuteronomy, the purpose of Boaz and Ruth’s levirate marriage is to raise up an offspring (Obed) that would continue the name of Mahlon, and not Boaz. In Ruth 4:4, Boaz even confirms this purpose is to perpetuate the name of the deceased (Mahlon). In the Gospel of Matthew, Sadducees also explicitly narrate that the brothers of the dead man would raise up seed for him to perpetuate the name of the dead man (Mat. 22:24-25; cf. Gen. 38:8-10). Therefore, the Law opposes the idea of Obed carrying the name of Boaz, and not Mahlon. This research employs the study of intertextuality to offer another perspective – Matthean perspective – on the problematic name of Boaz in the Bible genealogy: Ruth, 1 Chronicles, Matthew, and Luke.

Authors: Hasanah Nur Faridatul , Iswari Weningtyas Parama , Hermagustiana Istanti
Published: September 2024

Reading is a crucial skill that Indonesian learners are expected to master, as outlined in the 2013 Curriculum. Students are required to develop comprehension skills to understand both explicit and implicit information in a text. To assess students’ knowledge, teachers often use tests. During these reading tests, students may employ strategies to aid their comprehension. This study investigates the strategies used by secondary high school students at MA Darul Ihsan Samarinda during an English reading comprehension test, along with the challenges they face when using these strategies. This study employs a qualitative design to examine the strategies utilized by six students: high score, middle score, and lowest score. The data, gathered through the think-aloud method and interviews, is analyzed using thematic analysis. The findings reveal that students employed 23 out of 31 strategies to answer factual questions and 19 strategies for inferential questions. Both the high score and middle score students predominantly used the strategy of reading the text for clues in both types of questions. Conversely, the lowest score student primarily relied on the strategy of rereading the question. Despite the differences, all students utilized a meaning-based text strategy to choose their answers. The middle score and lowest score students frequently faced challenges with time management and complex vocabulary. Additionally, using mixed-method research designs could provide deeper insights into test-taking strategies. This study focused on the strategies used by high school students during reading tests, while other research has examined test-taking strategies in high-stakes language tests

Constructed wetlands (CWs) are considered one of the most efficient solutions for treating wastewater and reusing water resources. The present study aimed to monitor the performance of an integrated constructed wetland (ICW) located at NUST, H-12 campus, Islamabad. It has a sedimentation tank for pre-treatment, eight ponds planted with different vegetation (Typha latifolia, Pistia stratiotes, and Centella asiatica), and a FILTER (filtration and irrigated cropping for land treatment and effluent reuse) technology. The objectives of the present study were divided into the analysis of the physicochemical parameters, microbial analysis, and comparison with the past studies on the same ICW. The samples for physicochemical and microbial analysis were collected from four points, i.e., the inlet, sedimentation tank, pond 8, and collection tank. The results indicated that average temperature, pH, and DO range between 23.95-24.20, 6.95-7.20, and 2.25-3.10, respectively. Whereas other parameters showed the removal efficiency as follows: EC 10%, turbidity 73.99%, TSS 79.16%, TDS 32.60%, TS 47.22%, COD 69.01%, NO3-N 52.76%, NO2-N 50.53%, TKN 63.50%, and PO₄³⁻ 41.24%. Gram-negative bacteria with dominating microbial species such as Salmonella, Shigella, and E. coli were found to have a removal rate of up to 95%. The findings indicate that ICW is effective at removing pathogenic microorganisms, organic contaminants, nutrients, and maintaining temperature and pH changes in the water. Moreover, the comparison with past studies showed that the performance of ICW has been maintained over the years.

Son Doong Cave it is the largest cave on the planet and also the most majestic cave in Vietnam. Son Doong Cave is divided into habitats: Dark cave (covered by the cave ceiling) and light cave (not covered by the cave ceiling), including doline 1 and doline 2.Surveying and collecting land snail samples in Son Doong cave was carried out in January 2023. For the first time, the list of terrestrial snail species in Son Doong Cave was published. This includes 30 species (11 phenotyps are just only identified to genus) belonging to 24 genera, 11 families, 3 orders, 3 subclasses; of which  the presence of 5 species (Pincerna mouhoti, Leptopoma perlucidum, Scabrina patera, Chloritis khammouanensis, Amphidromus haematostoma) are newly recorded and added to the list of terrestrial gastropod fauna of Vietnam. In Son Doong cave, land snails are only distributed in the light part of the cave (Doline 1 and Doline 2), not in the dark part of the cave, which accounts for most of the cave area. Doline 2 has a higher species diversity (27 species belonging to 22 genera, 8 families, 2 orders) than Doline 1 (13 species belonging to 11 genera, 6 families, 3 orders). The diversity of land snail species in Son Doong cave is very unique and highly distinctive, but the species populations here is very small, requiring recommendations for tourists and the management board to protect vegetation to maintain and develop populations of this species.

Published: September 2024

The increase of freshwater aquaculture leads to the increasing demand for silkworms (Tubifex sp) as natural feed. Unfortunately, high demand of silkworm supply is not fully fulfilled yet because its availability is relied on natural catch. Cultivation of Tubifex sp. outside its natural habitats requires good information on substrates and feed. We aimed to study the effect of  mud, sand and their combination use as substrates in supporting Tubifex sp growth. This study used complete randomized design with 5 treatments, namely K1 (100% sand), K2 (100% mud), P1 (combination 75% mud-25%) sand, P2 (combination 50% mud-50% sand), and P3 (combination 25% mud-75% sand) with triplicates on each treatment. Research was conducted for 21 days using fermented chicken manure as feed. Tubifex sp growth was measured on biomass, number of individuals, and average body weight, while pH, temperature, dissolved oxygen and total organic matter were listed as measured environmental parameters. The use of sand and mud combination as substrate was better than a single sand or mud alone to support Tubifex sp growth. Combination of 75% mud and 25% sand showed the best growth of Tubifex sp as observed on biomass value of 13,244 g, 370 number of individuals, and average weight body of 2,741 mg. The application of a combination of sand and mud substrates has a potency to support the cultivation of Tubifex sp outside its native habitat.

Deteksi Pencemaran Mikroplastik pada Air Lindi di TPA Piyungan Yogyakarta Indonesia
Authors: Utami Inggita , Agustina Agustina
Published: September 2024

Piles of plastic waste at the Piyungan Landfill in Bantul Yogyakarta can be a source of microplastics and endanger if they accumulate in the bodies of living things. Data collection on microplastic contamination in leachate ponds at the Piyungan landfill is essential because the leachate will go to the Opak River, which is still used by the community. This study aimed to analyze the abundance and polymer types of microplastics in the leachate at the Piyungan landfill. The study was conducted from January to April 2021. Leachate samples were taken at the inlet pond (before treatment) and outlet pond (after treatment). The research stages include leachate sampling, filtering particles, drying samples, density separation, separation with organic compounds, and filtering supernatants containing microplastics. Identification of microplastics was carried out visually using a microscope, while the identification of polymer types was determined by the Fourier-transform infrared streptoscopy test. The data were analyzed quantitative descriptively, and inferentially to compare the average abundance value and determine the correlation between microplastic abundance and abiotic parameters. The analysis results showed the abundance of microplastics in the inlet pool of 154.8 ± 21.22 particles/L while in the outlet pool of 135.60 ± 12.18 particles/L. According to the T-paired test, it was found that the abundance of microplastics in the two ponds was not significantly different. Water temperature correlates with the abundance of microplastic in the leachate. The identified polymer types are Polystyrene (PS), Polyethylene (PE), and Polyvinyl Chloride (PVC), which are commonly used as raw materials for single-use plastic, food containers, and leachate sewer pipes. This study concludes that in the leachate at the Piyungan landfill, the highest microplastic was found in the inlet pond with polymer types, namely Polystyrene (PS), Polyethylene (PE), and Polyvinyl Chloride (PVC). Therefore, the Yogyakarta government needs to increase the leachate processing process to decompose this microplastic and not pollute the Opak river as a leachate disposal channel for the Piyungan landfill.

Timely, Granular, and Actionable: Designing a Social Listening Platform for Public Health 3.0
Authors: Kitchens Brent , Claggett Jennifer L. , Abbasi Ahmed
Published: September 2024

Every day, patients access and generate online health content through a variety of channels, creating an ever-expanding sea of digital data. At the same time, proponents of public health have recently called for timely, granular, and actionable data to address a range of public health issues, stressing the need for social listening platforms that can identify and compile this valuable data. Yet previous attempts at social listening in healthcare have yielded mixed results, largely because they have failed to incorporate sufficient context to understand the communications they seek to analyze. Guided by activity theory to design HealthSense, we propose a platform for efficiently sensing and gathering data across the web for real-time analysis to support public health outcomes. HealthSense couples theory-guided content analysis and graph propagation with graph neural networks (GNNs) to assess the relevance and credibility of information, as well as intelligently navigate the complex online channel landscape, leading to significant improvements over existing social listening tools. We demonstrate the value of our artifact in gathering information to support two exemplar public health tasks: (1) performing postmarket drug surveillance for adverse reactions and (2) addressing the opioid crisis by monitoring for potent synthetic opioids released into communities. Our results across data, user, and event experiments show that effective design artifacts can enable better outcomes across both automated and human decision-making contexts, making social listening for public health possible, practical, and valuable. Through our design process, we extend activity theory to address the complexities of modern online communication platforms, where information resides not only in the collection of individual communication activities but also in the complex network of interactions among them.
Performance Implications of Digital Disruption in Strategic Competition

Published: September 2024

Pervasive digitalization is changing how firms engage in strategic competition. Some firms are pursuing digital disruption strategies, using digital resources to rewire their value chain and change the landscape of their industry by redefining performance expectations. Other firms are adapting to digitalization by adding digital resources into their existing value chain. Through NK model simulations, we advance our understanding of digital disruption vis-à-vis adaptation in strategic competition in two main ways. First, we unearth important nuances in performance trade-offs: A digital disruption strategy may be effective for relative performance at the expense of absolute performance gains. Second, we explore relevant market- and competitor-related conditions under which firms should opt (or not) for a digital disruption strategy.

This study explores the therapeutic potential of Psidium guajava (Guava) and Jasminum grandiflorum (Chameli) leaves for oral ulcer treatment. Traditionally used in Ayurveda, these plants are rich in bioactive compounds. Ethanolic extracts were assessed for phytochemical content, antioxidant, and anti-inflammatory properties. Thin-layer chromatography (TLC) confirmed the presence of flavonoids, phenolics, tannins, saponins, terpenoids, steroids, glycosides, and alkaloids. Total phenolics and flavonoids were quantified using colorimetric assays. Antioxidant activity was evaluated through total antioxidant capacity (TAC) and ferric reducing power (FRAP) assays. Anti-inflammatory activity was assessed via albumin denaturation inhibition, anti-protease activity, and membrane stabilization assays. Antibacterial efficacy against Bacillus subtilis and Escherichia coli was tested using agar well diffusion. Guava extract exhibited higher total phenolic content (121.6 mg GAE/g) and comparable flavonoid content (280 mg QE/g) to Chameli. Both extracts demonstrated notable antioxidant activity, with Guava showing superior anti-inflammatory effects across all assays and antibacterial activity against both bacterial strains. These findings highlight the bioactive compounds contributing to the therapeutic potential of Guava and Chameli leaves. The developed herbal oral paste was effective in promoting healing, supporting its potential for oral ulcer treatment, although further clinical validation is needed.
Feared and forgotten; but no more.

A rapidly aging population is resulting in increasing numbers of people with dementia. Unfortunately, the New Zealand population affected by this medically incurable disease are eventually being forced into institutionalised aged care facilities. The lack of human-centred design in these facilities results in numerous problems that fundamentally induce a poor quality of life (QoL) and wellbeing of the service users. Architecture has the proven capability to not only give the individuals a sense of autonomy, but also decelerate, and in some cases stabilise, their health and wellbeing. Providing an opportunity to allow this growing population to enjoy a greater quality of life, like the rest of us.

This thesis explores existing literature that ought to solve issues experienced by service users in current aged care facilities. While also examining successful case studies which implement these solutions, I aspire to create a ‘home away from home’ for not only the service users, but the wider dementia community inclusive of nurses, caregivers, families, and the local community. A research-through-design methodological approach will hope to determine how can architecture improve the quality of life and prolong the general wellbeing of people living with dementia? The need for specifically designed architecture in terms of wayfinding, environment and activity was identified in the literature review to provide a sense of autonomy, identity and stimulation for the service users. This will form the framework for this design.

Applying this gained knowledge to a research-through-design methodology, should produce an optimum outcome. This research intends to build a model that utilises the specific design strategies discovered that reduces the problems commonly experience by the service users. This model hopes to create a necessary movement in New Zealand away from institutionalised aged care facilities and towards specialised environments carefully designed for people with Dementia.
DeBakey Type III Aortic Dissection Causing Bowel Necrosis: A Case Report

Published: September 2024

Rationale: Aortic dissection is a life-threatening medical emergency associated with high morbidity and mortality. Preoperative mesenteric malperfusion increases the surgical risk and mortality in patients with type B aortic dissection. For DeBakey type III B patients involving most of the thoracoabdominal aorta, endovascular treatment to improve true lumen perfusion may have limited benefits. Organ reperfusion on-time is crucial. Patient concerns: A 38-year-old man was admitted with sudden severe upper abdominal pain. Emergency CTA of the entire aorta revealed an aortic dissection with an entry tear in the descending aortic arch involving the celiac trunk, superior mesenteric artery, bilateral common iliac arteries and right external iliac artery, with thrombosis in the superior mesenteric artery. Diagnoses: The patient was diagnosed with DeBakey type III aortic dissection with mesenteric artery embolism. Enhanced chest CT showed the entry tear location and involvement of major arteries. Angiography confirmed partial blood flow in the superior mesenteric artery. Interventions: The patient underwent endovascular aortic stent-graft implantation through the left femoral artery, covering the descending aortic arch and sealing the entry tear. Postoperatively, the patient received intensive care, including ventilatory support, CRRT, anti-infection therapy, vasoactive drugs and lumbar cistern drainage. Outcomes: Two weeks postoperatively, the patient developed massive black stools, indicative of intestinal obstruction and necrosis. Exploratory laparotomy revealed ischemic necrosis and rupture of the stomach, small intestine, and colon. Despite surgical efforts, the patient’s condition deteriorated, leading to death from severe infection, acid-base imbalance and multiple organ failure.

En 1860, tras la crisis que amenazó la integridad del Estado ecuatoriano, surgió la necesidad imperiosa de establecer un gobierno sólido y moderno; es así que aparece la figura de Gabriel García Moreno en un momento de crisis a nivel nacional, cuando el Estado ecuatoriano enfrentaba la posibilidad de desintegrarse, fue el quien implementó un proyecto destinado a consolidar y modernizar el Estado; introdujo el sufragio universal, promovió el desarrollo cultural, técnico y científico, estableció una red vial nacional e inició la construcción del ferrocarril. García Moreno, visto como un presidente ejemplar por algunos y como un dictador por otros, tenía un ideal claro: fomentar la unificación entre las regiones Costa y Sierra. Su meta era mejorar el comercio y la comunicación a través de la introducción de un medio de transporte, particularmente un sistema ferroviario. En 1895, Eloy Alfaro, un presidente de tendencia liberal y con un fuerte deseo de completar el proyecto del ferrocarril, asumió el poder. Alfaro, simpatizante de Estados Unidos, tomó la decisión de continuar con la construcción del ferrocarril. “El ferrocarril más difícil del mundo”, para ello, contrató a dos ingenieros norteamericanos: Archer y John Harman, siendo Archer el más experimentado en construcción de ferrocarriles. Alfaro denominó el proyecto como "redentor" porque su propósito era facilitar una comunicación y comercio efectivos entre diferentes regiones del país. Además, este proyecto cumplía con los requisitos necesarios para el desarrollo económico y la transición hacia el capitalismo, dejando atrás los antiguos modelos económicos y sociales. Es cierto que la construcción de la línea del ferrocarril dejó con una gran deuda a Ecuador; sin embargo, el desarrollo social del país mejoró notablemente, la comunicación entre la Costa y la Sierra, el comercio, los viajes que parecían imposibles por los Andes antes del ferrocarril, ahora se los podía realizar en cuestión de horas, de esta forma Ecuador pasó a ser un país reconocido para el resto de Sudamérica y el mundo.
