Current Trends of Alternatives to Hysterectomy in Adenomyosis: A Review Article
Authors: Zeba Dilruba , Rahman Riedwan Habibur , Rahman Raiyan Muhibur , Biswas Rajib
Published: November 2023

Adenomyosis is a common gynecological problem characterized by the growth of endometrial glands and stroma within the myometrium. Previously, the definitive diagnosis of adenomyosis was made through histopathology after a hysterectomy. However, in the last two decades, several uterine-sparing treatment options have emerged, including High-Intensity Focused Ultrasound (HIFU), which has become a promising option. HIFU is a non-invasive local thermal ablation technique that can be performed via ultrasound or MRI guidance. Additionally, “Laparoscopic uterine artery occlusion with uterus sparing pelvic plexus block and partial adenectomy for adenomyosis” has become a popular option. While conventional adenomyomectomy carries a high risk of recurrence and uterine rupture, some novel surgical techniques have been described to mitigate these complications and preserve future fertility. There are also “new surgical techniques of laparoscopic resection of adenomyoma under real-time intraoperative ultrasound elastography guidance”. Diagnostic imaging techniques such as transvaginal ultrasound, MRI, and hysteroscopic evaluation have revolutionized the diagnosis of adenomyosis and opened up possibilities for conservative treatment options. Hysteroscopy can be used for direct visualization and biopsy collection, though it is not the first-line treatment option. With the increasing incidence of adenomyosis and the desire for fertility preservation among younger patients, there is a growing need for effective uterine-sparing treatments.

Published: November 2023

Actualmente en América Latina, la construcción regular de muros de hormigón armado para estructuras de hasta dos plantas es una analogía al método utilizado en los edificios de gran altura. Los muros están diseñados con una doble capa de malla de acero horizontal y vertical. Sin embargo, el uso de refuerzo de doble malla implica una cantidad de acero mucho mayor que la necesaria para los diseños de muros de estructuras de poca altura. Este estudio tiene como propósito realizar pruebas experimentales para evaluar el comportamiento sísmico de muros delgados de concreto armado con un solo refuerzo central. El plan experimental consideró una prueba de 6 muros en una proporción de 1:1. del WSL1 al WSL6, los muros tienen una longitud de 1600 mm (lw), una altura de 1600 mm (hw) y un espesor de 100 mm (tw), todas las muestras se construyeron con una viga superior para aplicar cargas horizontales y una viga inferior para sujetar los muros al suelo. Se ha observado a partir de ensayos experimentales que el comportamiento y falla de los muros se controla mediante el corte. La mayoría de las primeras grietas observadas en la muestra son grietas diagonales. Las variables estudiadas en el análisis de resultados fueron: cuantía de malla de refuerzo, tipo de acero (malla o refuerzo corrugado), cuantía de refuerzos de borde vertical. Además, se analizaron los resultados experimentales para evaluar el efecto del refuerzo de borde, cuantía de mallas soldadas, el tipo de acero y cuantía de armaduras convencionales.

Published: November 2023

La calidad del agua superficial en cuencas con baja oferta y alta demanda de este recurso, debe evaluarse principalmente en países en desarrollo. Sin embargo, por la disponibilidad de recursos, únicamente se ha venido considerando a los parámetros fisicoquímicos para hacerlo, por lo que el relacionar elementos bióticos y abióticos permitirá conocer el estado ecológico, como una lectura más integral de la salud o calidad del ecosistema acuático. Por ello, el objetivo de este estudio fue estimar la calidad ecológica en microcuencas con diverso estado de conservación del suelo y que abastecen con agua para su potabilización en la ciudad de Loja al Sur del Ecuador. Para ello, fueron usados diversos índices bióticos, partiendo desde los más comunes como los índices de diversidad, el índice ABI (Andean Biotic Index) basado en el BMWP (Biological Monitoring Working Party), el EPT (Ephemeroptera, Plecoptera y Trichoptera); y el índice de calidad de hábitat SVAP (Stream Visual Assessment Protocol). Los resultados de estos índices ubican a las tres microcuencas que abastecen actualmente de agua (San Simón, El Carmen y Mendieta) con buena calidad; sin embargo, no se deben descuidar sus condiciones de uso, manejo y conservación. Para las dos microcuencas restantes, se estimó una calidad de agua dudosa debido al impacto de ciertas actividades antrópicas que se presentan en ellas. Por esta razón, usar el índice de calidad ecológica (ICE) en cuencas abastecedoras de agua, puede ser muy útil para la gestión integral de cuencas, el ordenamiento territorial, o generar normativa por parte de los gobiernos autónomos descentralizados (GAD) con una visión más holística y prospectiva.

ABSTRACT : Availability of Polystyrene (PS) type plastic waste in various surrounding environments, added to the hot asphalt mixture to improve road pavement performance. This study aims to determine the effect of adding Polystyrene (PS) plastic to the Marshall characteristics of AC-WC and AC-BC asphalt based on the 2018 General Highways Specifications. The test results on Marshall characteristics with a mixture of normal asphalt content of 5% and 6% obtained Optimum Asphalt Content (KAO) of 5.5% for each asphalt AC-WC and AC-BC. Marshall testing on AC-WC asphalt with polystyrene materials using 4% and 5% levels. Then the Stability, VMA, VIM, Flow, and Marshall Quotient values increase, while the VFA value decreases with each addition of Polystyrene (PS) content, this indicates the low density of the asphalt mixture against water and air. However, all variations in the levels of plastic additives on AC-WC asphalt met the specifications, while the Marshall test on AC-BC asphalt with polystyrene materials used levels of 4% and 5%. Then the Stability, VFA, Flow, and Marshall Quotient values have increased, while the VMA, and VIM values have decreased with each addition of Polystyrene (PS) content, this indicates that the voids in the aggregate and voids in the mixture are getting smaller, and causing the asphalt to not be able to fill the empty space too much. and aggregate binding. However, only the VIM value at 5% with a value of 2.58% does not meet the specifications between 3% -5%. So, apart from that, all the added ingredients of asphalt plastic AC-BC meet the specifications. Utilizing Polystyrene (PS) type plastic waste in hot asphalt mixtures can improve the quality of Marshall characteristics and can be used as an additive in asphalt flexible pavement.Â Keywordsi : AC-WC, AC-BC, Marshall, KAO, Polystyrene (PS).

Published: November 2023

The research identifies factors influencing consumer preferences of kasbi sago (Sagu Jay Brand) purchasing decision. It conducts in Ternate from July to December 2020. The kasbi sago from Sagu Jay Brand is produced in Jaya Village, distributed through collectors, and marketed in Ternate City. The brand is chosen because the village is a center of Sagu Jay sales with the highest consumer demand in North Maluku compared to other kasbi sago production. The research is a survey research using qualitative and quantitative methods. The qualitative aims at identifying research descriptions derived from traders in marketing the Sagu Jay product and related respondents. The qualitative data are then quantified by processing the data to generate tabulated valid data. The quantitative data are numeric or values in the variable are expressed in real numbers (Sugiono, 2014). Research variables to be observed include cultural, price, flavor, and purchase location factors. Consumer preference sampling refers to expertsâ€™ opinion that sampling used to obtain representative data is a non-probability sampling, namely accidental sampling. The research analysis method used is conjoint analysis. The research results of factors influencing consumer preferences of Sagu Jay purchasing decision in Ternate indicate that flavor factor at the original level (1.921) and the chocolate level (1.668) are dominant factors and levels that form consumer preferences. The second dominant factor is the texture factor at the dry level (0.918) followed by the price factor at the level of Rp. 10.000 (0.576), and purchase location factor at the level of Pasar Kota Baru (0.060). The lowest factor is cultural factors at regional acceptability (0.29). This suggests that the consumers prefer kasbi sago products from the Sagu Jay brand due to the flavor factor at the dry level than other factors.

Materials and Methods: A descriptive observational study was carried out among total population of consenting health workers (medical doctors, laboratory scientists / technologists, and technicians) in the Surgery and Diagnostic Services Departments in two teaching hospitals in Port Harcourt, using self-administered questionnaires. Data on experiences and challenges was analysed using the Statistical Package for Social Sciences (SPSS) version 20.0. Results: The respondents had a male to female ratio of 1.3:1, mean age of 35.47 ± 8.44 years, mean years in practice of 7.58 ± 6.97 years, and 171 (98.3%) were Christians. One hundred and sixteen (66.7%) respondents were aware of delay in diagnostic services, in varying degrees. Lack of reagents (49 = 28.2%), inadequate personnel (18 = 10.3%), long processing time (15 = 8.6%) and poor electric power supply (9 = 5.2%) were the most common reasons for delay in diagnostic test results. Diagnostic challenges were highlighted, occurrence of medico-legal issues was reported, and solutions proffered. Conclusion: The professionals practicing in the diagnostic / surgical departments were aware and do experience delays in diagnostic test results and errors (reported by a few) that affects surgical services in our environment. Their experiences and challenges were highlighted and recommendations were made.

A Study on the Association between Skiers’ Body Fat Percentage and Their Jump and Sprint Performance
Authors: Sevindik Aktaş Buket
Published: November 2023

This study was conducted to analyse the correlation between elite skiers’ body fat percentage (BFP) and their jump and sprint performance. From among different disciplines of snow sports (alpine skiing, cross-country skiing, snowboarding, ski jumping, and biathlon), a total of 40 (male) elite athletes with a mean age of 18.55±2.86 year, a mean height of 172.1±6.05 cm, and a mean body weight of 65.73±10.79 kg were included in this study, and their anthropometric (height, body weight, body mass index, and BFP) and performance (10-30 meters sprint and vertical/horizontal jump) measurements were taken. In order to determine the suitability of the data for normal distribution, the Pearson Correlation Coefficient test was used to analyse the correlations between variables upon assuming normal distribution by using the Shapiro-Wilk test. As a result, negative correlations were found between 10-30 m sprint and horizontal jump performances and the disciplines of cross-country skiing, ski jumping and biathlon. Further negative correlations were found between vertical jump and 30 m sprint in snowboard branch, while positive correlations were present between 10-30 m sprint and BFP in the disciplines of cross-country skiing, ski jumping and biathlon. However, there was also a strong negative correlation between horizontal jump and BFP in the discipline of ski jumping. It can be suggested that high BFP negatively affects the sprint and jump abilities of the athletes since the skiers’ jump performance appears to decrease with the increased BFP, and likewise, their jump performance increases with the decreased BFP.

Published: November 2023

The geosystem of the Anapa bay-bar is a zone of contact and mixing of aquatic, psammophilic and steppe ecosystems. The location on the "land-sea" border leads to the sensitivity of the geosystem to external influences and high variability, in particular, of the relief. On the basis of complex field and remote studies, the vegetation of the coastal-marine geosystem of the Anapa bay-bar and its role in the formation of the relief are characterized in the presented work.

Published: November 2023

The monitoring of the state of the ecosystems of the Arctic seas is both an urgent practical task in the face of ever-increasing anthropogenic pressure on fragile Arctic ecosystems, and a fundamental scientific task, because for its implementation it is necessary to solve a number of important scientific issues. A reliable assessment of the state of biological diversity in marine ecosystems is associated with the need to have accurate data on the species composition of benthic and plankton communities. The development of a method for assessing the biological diversity of marine communities by metagenomic analysis opens up a promising way to solve this problem.

Acute sialoadenitis (К11.2 МКБ 10) is one of the early post-operative complications. Swelling and infiltration of the salivary glands occur within a few minutes to 24 hours after surgery. This post-operative sialadenitis resolves spontaneously within 1–5 days, but rarely it can lead to serious complications. We present the clinical case of a 62-year-old female who underwent a spinal surgery in the prone position under general anesthesia. Three hours after the operation, we noted swelling of the neck, signs of acute respiratory failure, which required observation in intensive care unit and re-intubation of the trachea. Within 72 hours, swelling and infiltration of the salivary glands decreases. The patient was extubated and transferred to the neurosurgical department. Thus, acute post-operative sialoadenitis can cause the upper airway obstruction.

The aim of the study was to estimate the significance of delayed percutaneous coronary interventions (PCIs) in the treatment of ST-segment elevation myocardial infarction (STEMI), to weigh the initial mortality risk (MR) while determining the indications for their use and the time window for the use of mechanical reperfusion in late hospital admission. Total 2226 patients admitted to the Institute with STEMI for the period 2008–2017 were studied. Emergency coronary angiography was performed in 945 admitted patients in the initial 12 hours and in 834 patients after 12–72 hours of STEMI onset; PCI was performed in 784 and 619 patients, respectively. In all patients, MR was scored by TIMI; angiographic success was assessed as TIMI 3 coronary flow and compared to ECG signs of reperfusion. The baseline MR score averaged 5 or 12.5%, being corresponded to score 4.2 or 8% in patients with PCI performed in the initial 12 hours, score 5 or 12.5% in those with PCI performed after 12–72 hours, and score 6 or 16% in patients without PCI; or with respect to the patient age, MR scored 3.7 or 7%, 6 or 16%, and 7.5 or 25%, for those under the age of 65 years, those from 65–75 years, and those over 75 years old, respectively. Mortality in patients with an early and delayed PCI was 5.2% and 4.2%, respectively, and 15.6% in patients without PCI; after patient distribution by age under 65, 65–75, and over 75 years old, the respective mortality rates were 3.8%, 4.9%, and 10.8% after an early PCI; 2.6%, 5.8%, and 8.2% after a delayed PCI; and 8.4%, 19.4%, and 28% among those without PCI. For 10 years, the number of primary PCIs had increased from 39% to 78%. The ratio of early to delayed PCI made 56% to 44%. Of 195 deaths (67 patients with PCI and 128 without PCI), 90% of patients had a three-vessel disease; 83% of patients had the MI area over 30%; and the cause of death in 84% was pulmonary edema. The presented data suggest a high practical significance of delayed PCI in patients with initially high MR, its most weighty components being the age over 75 years and severe manifestations of acute heart failure (AHF). Unlike early PCIs, the delayed PCIs are used less frequently, the initial MR is not taken into account, and they are abstained from in respect to people over 75 years of age. The reduction in mortality, proportional to the baseline MR, suggests their correlation to PCI results and the feasibility of PCI use without age restrictions. The use of primary PCIs in late hospital admissions, by analogy with early ones or selectively in high MR, will help to optimize the treatment tactics and minimize mortality.

This article explores the enduring mysteries of consciousness and the afterlife, two enigmatic topics that have fascinated humanity for ages. Despite extensive scientific efforts, the existence of an afterlife remains unproven, and understanding consciousness remains a significant challenge. The research introduces innovative hypotheses through simple thought experiments with empirical evidence and robust theoretical foundations. It delves into the complexities of consciousness, its relationship with the brain, and the need for interdisciplinary approaches encompassing physics, psychology, and philosophy. Boldly contemplating the probability of a continuous consciousness after death, the study argues that existing evidence strongly supports this idea. Beyond theoretical implications, it envisions practical outcomes, suggesting that insights into these mysteries could enhance human well-being and contribute to a more harmonious world. In summary, this article embarks on a quest to shed light on age-old questions about consciousness and the afterlife. Through fresh methodologies, it aims to provide new perspectives that could reshape our understanding of existence and inspire intellectuals to positive individual and societal advancements.

Published: November 2023

Segitiga komponen packing merupakan salah satu komponen pendukung dalam proses packing di PT. Surabaya Autocomp Indonesia yang memiliki beberapa ukuran. Dalam menghasilkan ukuran-ukuran tersebut, diperlukan suatu sistem yang presisi, salah satunya menggunakan motor stepper.

Rangkaian pulsa digital dikirimkan ke motor stepper untuk mengontol kecepatan dan sudut rotasi pada motor. Metode penelitian yang diterapkan adalah kuantitatif eksperimen, dilakukan dengan mengkaji persamaan matematis yang digunakan untuk rumus konversi. HMI akan memberikan input nilai jarak kepada PLC. Kemudian PLC akan mengkonversi nilai jarak menjadi nilai pulsa. Motor stepper diberikan pulsa oleh PLC melalui driver motor untuk mengendalikan langkah (step) motor supaya berputar sesuai input yang diinginkan HMI

Setelah melakukan tiga kali percobaan nilai konversi, didapat nilai error terkecil pada percobaan ketiga yaitu, 0.19% dan 0.04%. Hal ini dikarenakan faktor konversi yang kurang akurat dan faktor mekanik yang kurang presisi dalam perakitannya.
