Published: April 2024

Purpose: This study aimed at giving evidence on prevalence and factors associated with anastomotic leakage among patients undergoing bowel resection and anastomosis at Bugando Medical Centre (BMC) and Sekou Toure Regional Referral Hospital (SRRH).
Methodology: A descriptive cross-sectional analytical study was used involving patients undergoing bowel resection and anastomosis at Bugando Medical Centre and Sekotoure regional referral hospital over a four-month period from March 2017 to June 2017 inclusive.
Findings: Eight out of 144 patients (5.6%) developed anastomotic leakage. The common indication for surgery was sigmoid volvulus, the common performed anastomosis was ileo-ileo end to end, and double layer continuous anastomotic suture was the common method of anastomosis Anemia (0.012), presence of premorbid illnesses (p=0.003), American association for anesthesia (ASA) greater than II (p=0.001), intraoperative contamination/sepsis (p< 0.001), low ranked operator (p=0.046), prolonged duration of operation (p=0.001), and delayed passage of stool and flatus (p=0.001) were found to be variables associated with anastomotic leakage among study participants. Anastomotic leakage in our setting occurs in approximately 5.6% of patients operated. Several factors such as high American society for Anesthesiologist above III, premorbid condition such as uncontrolled Diabetes Mellitus, intraoperative contamination/sepsis, low ranked operator, prolonged duration of operation above 3 hours and prolonged ileus were among factors that the present study found to be associated with high risk of anastomotic leakage.

This work is based on the investigation of uranyl (VI) ion adsorption onto natural diatomite using batch sorption method under different parameters such as pH, initial ion concentration, adsorbent amount and effect of sulfate ion as a foreign ion. 8-hydroxyquinoline is used as a chromogen forming a pale-yellow complex with ions in chloroform, the absorbance was measured spectrophotometrically at λmax 460 nm, obtaining a linear calibration curve with R2=0.998, LOD=3.03 mg/L and LOQ=9.21 mg/L. Prior to the implementation of the batch experiment, the morphology and composition of diatomite was confirmed using XRF (Bruker S8 Tiger), XRD (Bruker D5005), FTIR (Bruker Vector 22), and SEM (JEOL JSM-5610 LV) techniques. From spectrophotometric analysis, the results showed that the maximum uranyl ion adsorption distribution coefficient reached at the initial concentration of 50ppm, pH 4.5, contact time 5hrs and adsorption dosage of 2 g/L. There was no significant effect of sulfate ion on the adsorption affinity. Adsorption isotherm was studied by Langmuir which was favourable model fitting with R2=0.996 and maximum adsorption capacity of 16mg/g, and separation factor RL = 0.0122. Freundlich isotherm model also applied for the same data and give a very straight line with R2= 1.00 and maximum adsorption capacity of 200 mg/g. Temkin model was less fit and gave a negative isotherm curve with R2= 0.78, KT= 0.9405 L/g, bT= 24.724 J/mol. Langmuir and Freundlich isotherms gave exothermic adsorption while Temkin gave an endothermic one.

The study holds significance in revealing how ensuring fair access to education can fuel economic growth, promote social cohesion, and guide policymaking for sustainable development. The objective of current research is to empirically examine the relationship between gender disparity in educational attainment within social, and ecological systems. The data is collected for the period 1990-2022. In the presence of cross-sectional dependence 2nd generation unit root test is applied. CS-ARDL technique is considered to examine the short-run as well as the long-run relationship between Gender disparity in education and the socio-ecological system. Achieving environmental sustainability and minimizing our ecological footprints depend critically on gender parity in education. Equal access to high-quality education gives women the knowledge, analytical abilities, and self-assurance to stand up for their communities and themselves. Findings describe that in the long run, there is a statistically significant negative correlation between the GINI-Coefficient and school enrollment tertiary and School enrollment primary. This indicates that, over time, a decrease in income disparity is linked to an increase in enrolment in primary and postsecondary education. In the long run, the GINI-Coefficient and Secondary school enrollment has a positive and statistically significant relationship. The data in Model 2 appear to indicate that the relationship between education and environmental sustainability is more intricate than the EKC hypothesis predicts. Higher education can raise one's knowledge and understanding of environmental issues, but it can also increase consumption and have an adverse effect on the environment. The findings of the study suggest that implementing policies with the goal of removing obstacles to education based on gender. This could entail giving families financial incentives to send their daughters to school and making sure that all genders have access to high-quality education.
Intelligent, optimal charging with MSSC and PCM protocols for healthy and long life on Li-ion batteries

Published: April 2024

MSCC is one of the most efficient charging methods with the appropriate advantages over the CC/CV method most commonly used in the Li-ion battery charger market. Our approach to this optimal charging is based on the weak points of CC/CV charging, as well as the battery's reaction after each CC step in testing the new optimal current. Given the needs of the industrial market, which demands fast charging and safety against overcharging and side effects, we decided to develop a fast, optimal charging method aimed first and foremost at guaranteeing a long battery life cycle. Our intelligent charging strategy uses a combination of two charging protocols, MSSC and PCM, each with functionality and a communication link via an STM32 MCU. The principle is to find the optimum charging current for the battery at each stage of charging, depending on its state of health, and then apply the MSSC with a modern, optimized method based on methodological calculations, always respecting the temperature conditions.
Finally, based on several experimental tests, we were able to prove that the optimal, intelligent method proposed in this article reduces charging time by 16.8% and temperature by 20%, compared with our own intelligent CC/CV+PCM method.
Anatomic location of the first dorsal extensor compartment for surgical De-Quervain’s tenosynovitis release: A cadaveric study
Authors: Thandoni Aditya , Yetter William Nicholas , Regal Steven Michael 
Published: April 2024

BACKGROUND
De-Quervain’s tenosynovitis is a disorder arising from the compression and irritation of the first dorsal extensor compartment of the wrist. Patients who fail conservative treatment modalities are candidates for surgical release. However, risks with surgery include damage to the superficial radial nerve and an incomplete release due to inadequate dissection. Currently, there is a paucity of literature demonstrating the exact anatomic location of the first dorsal extensor compartment in reference to surface anatomy. Thus, this cadaveric study was performed to determine the exact location of the first extensor compartment and to devise a reliable surgical incision to prevent complications.
AIM
To describe the location of the first dorsal compartment in relation to bony surface landmarks to create replicable surgical incisions.
METHODS
Six cadaveric forearms, including four left and two right forearm specimens were dissected. Dissections were performed by a single fellowship trained upper extremity orthopaedic surgeon. Distance of the first dorsal compartment from landmarks such as Lister’s tubercle, the wrist crease, and the radial styloid were calculated. Other variables studied included the presence of the superficial radial nerve overlying the first dorsal compartment, additional compartment sub-sheaths, number of abductor pollicis longus (APL) tendon slips, and the presence of a pseudo-retinaculum.
RESULTS
Distance from the radial most aspect of the wrist crease to the extensor retinaculum was 5.14 mm ± 0.80 mm. The distance from Lister’s tubercle to the distal aspect of the extensor retinaculum was 13.37 mm ± 2.94 mm. Lister’s tubercle to the start of the first dorsal compartment was 18.43 mm ± 2.01 mm. The radial styloid to the initial aspect of the extensor retinaculum measured 2.98 mm ± 0.99 mm. The retinaculum length longitudinally on average was 26.82 mm ± 3.34 mm. Four cadaveric forearms had separate extensor pollicis brevis compartments. The average number of APL tendon slips was three. A pseudo-retinaculum was present in four cadavers. Two cadavers had a superficial radial nerve that crossed over the first dorsal compartment and retinaculum proximally (7.03 mm and 13.36 mm).
CONCLUSION
An incision that measures 3 mm proximal from the radial styloid, 2 cm radial from Lister’s tubercle, and 5 mm proximal from the radial wrist crease will safely place surgeons at the first dorsal compartment.

Authors: Thomas Preussler Vanda , München Sinara 
Published: April 2024

Este artigo teve como objetivo identificar pesquisas vinculadas a Educação, Ciência, Tecnologia e Sociedade (CTS) no Ensino Médio através de uma revisão bibliográfica em trabalhos da Biblioteca Digital de Teses e Dissertações (BDTD) do Instituto Brasileiro de Informação em Ciência e Tecnologias (IBICT). A abordagem metodológica é qualitativa do tipo bibliográfica, seguindo pressupostos metodológicos para compor um estado do conhecimento. Os trabalhos foram analisados adotandoa metodologia da Análise Textual Discursiva, organizando os resultados em duas categorias emergentes: (1) Implicações da realidade escolar e da motivação dos alunos na formação e atuação do professor, com perspectiva CTS; (2) Percursos e resultados da formação e da prática de professores, com perspectiva CTS, no Ensino Médio. Os resultados encontrados evidenciam uma realidade escolar fragilizada, compreensões limitadas dos professores sobre CTS e apontam a formação docente como direção para o desenvolvimento de práticas pedagógicas articuladas à educação CTS. A falta de planejamento coletivo é um fator limitante assinalado pela pesquisa ao desenvolvimento de novas propostas de ensino e a mudança de postura dos professores em relação ao ensino interdisciplinar é um destaque da pesquisa, tendo em vista ser um fator relevante para alavancar a educação baseado na tríade CTS.
O ENSINO DE CIÊNCIAS FACE A HEGEMONIA DA RACIONALIDADE NEOLIBERAL: DESAFIOS E TENSIONAMENTOS NA ORGANIZAÇÃO CURRICULAR

Published: April 2024

Resumo: No contexto contemporâneo, o neoliberalismo tornou-se uma racionalidade hegemônica, transversalizando os diferentes fenômenos culturais, sociais e políticos. Estas mudanças na esfera mercantil reverberam nos âmbitos psíquicos, provocando uma reconfiguração antropológica. Diante disso, reconhece-se que as propostas curriculares para o Ensino de Ciências não são inócuas às mudanças macroestruturais e a emergência do neosujeito, passando a ser tensionadas pela razão-mundo hegemônica. Neste ensaio, discorre-se acerca dos desafios e tensionamentos da hodiernidade ao Ensino de Ciências, evidenciando a necessidade de inserção de tópicos de História e Filosofia das Ciências no currículo escolar, a fim de formar capacidades necessárias para o bem estar político e econômico da sociedade. A fim de realizar o objetivo proposto, na primeira seção do ensaio disserta-se acerca da constituição subjetiva dos neosujeitos, argumentando que este indivíduo é incapaz de participar de discussões de caráter aprofundado, na medida em que prioriza a busca pelo entretenimento em substituição ao estudo necessário para compreender a complexidade do mundo. A ênfase no pragmatismo e na satisfação pessoal, promove o surgimento de novas expectativas sociais e políticas em relação à educação, induzindo mudanças endǵenas nas propostas curriculares. Na segunda seção, discorre-se acerca destas mudanças pedagógicas, realizando uma crítica aos fundamentos neoliberais subjacentes a elas. Enfatiza-se que a autorreferencialidade e o hedonismo promovidos por tais mudanças, levam à morte do homem público. Diante desse cenário, urge a necessidade de revisitar os fundamentos do Ensino de Ciências, reapropriando-se de uma gramática pedagógica perdida pela hegemonia da razão neolieral. Soma-se a isso, a urgência de pensar o lócus escolar como espaço de promoção do raciocínio, bem como um convite para desvelar a complexidade do mundo e realizar um julgamento crítico em relação ao mundo e as escolhas humanas. Na terceira seção, adota-se uma postura prognóstica, anunciando as possibilidades de organizar um currículo escolar que tenha como compromisso a formação de uma racionalidade contra-hegemônica, por meio da inclusão de tópicos de História e Filosofia das Ciências.

Published: April 2024

: Every year, more than a million women are diagnosed with breast cancer, and over 700.000 of them have positive for hormone receptors (FIR). The expression of key markers, such as ER and PP, and clinical circumstances show specific biological traits. Risk factors may have a role in the development of some hormone receptor-positive breast cancers. Objective: The objective of this study was to investigate the correlations between key tumor markers, including HER2, ER, PR, ALP, and KI67, in hormone receptor-positive breast cancers. Methods: Tumour tissue samples were collected for histopathology (10% neutral buffered Formalin-fixed paraffin-embedded tissue specimens) during Trucut biopsy or mastectomy at the oncology department of a tertiary care hospital in Karachi from October 2022 to July 2023. Tissues were analyzed under a light microscope for tumor hormone receptors at a tertiary care hospital in Karachi. Results: There were several significant correlations observed between HER 2 NUE, KI 67, ER, and PR. Specifically, a weak negative correlation was noted between HER 2 NUE and KI 67, while weak positive correlations were observed between HER 2 NUE and both ER and PR. Additionally, a weak positive correlation was found between ER and HER 2 NUE, PR, and KI 67, and a weak positive correlation existed between PR and ER, HER 2 NUE, and KI 67. Finally, KI 67 displayed a weak positive correlation with HER 2 NUE, PR, and ER. Conclusions: Her two nurses, ER, ALP, KI 67, and breastfeeding, are significantly and directly related. PR is not significantly related to other mentioned tumor markers.
