Online pedagogy: a changing higher education pedagogy and an emerging lecturer habitus
Authors: Mantashe Lunga Xolisa
Published: November 2023

This study explored how the shift to online pedagogy has shaped lecturer dispositions and practices for a post-COVID-19 era, including whether their practices during the national lockdowns could be conceptualised as temporary coping mechanisms or as an adoption of new practices related to effective modes of online teaching. Bourdieu’s theory of human practices was employed to facilitate the exploration. The theory privileges the weight of past practices on agents while permitting incremental changes in such practices, depending on the flexibility and/or rigidity of a human habitus. Six lecturers were interviewed using semi-structured interviews to collect data. It was found that despite showing flexible and reflective dispositions regarding post-COVID-19 online teaching, participants were still in their exploratory phase in respect of teaching practices with online technology tools. An explicit institutional, reflective training process is suggested to help evolve in lecturers the habitus and cultural capital necessary to facilitate teaching with technology.
The use of M-learning to foster the development of self-regulated learning in university students: A systematic review
Authors: Nyirenda Ishmael , Simuja Clement
Published: November 2023

The rapid development of mobile technologies and their price decrease have enabled mobile devices to become ubiquitous. Both lecturers and students are integrating mobile technologies into teaching and learning. The continuous global innovation in emerging mobile technologies and their ever-increasing overlap with the lives of students and lecturers in Higher Education Institutions (HEIs) have thrust Mlearning and self-regulated learning into prominence. Accordingly, this review analyses conference proceedings and national and international journals on the potential of M-learning for fostering self-regulated learning. To select relevant sources, a systematic literature review approach was employed. This study fills gaps in existing literature and investigates how mobile devices might enhance self-regulated learning among university students. It also signals future research directions and offers implications for researchers and practitioners in HEIs.
Proctoring as a human substitution for online summative assessments in a comprehensive open distance e-learning institution: Opportunities and obstacles
Authors: Jacobs Lorette , Mncube Siphamandla
Published: November 2023

At a comprehensive open distance e-learning (CODeL) university in South Africa, assessment practices were converted and offered online during and post COVID-19. Innovative proctoring methods were applied to secure the authenticity of online summative assessments. However, the use of such proctoring tools to ensure ethical behaviour of students during summative assessments remains questionable, as these tools are not infallible. A qualitative approach was applied to explore ways in which online proctoring tools can contribute toward ensuring authentic summative assessments. Through the application of collaborative autoethnography, the researchers obtained insight into opportunities and obstacles that may influence the effective use of online proctoring tools to support summative assessment activities. Findings indicate that students would go to great lengths to consult unauthorised material and share answers during summative assessments. Therefore, to enhance perceptions of ethical conduct in higher education, it is recommended that ethical principles are expanded through extended training and guidance with revolutionised proctoring technologies.
Students’ perceptions of Computerised Adaptive Testing in higher education
Authors: Ramgovind Proya , Pramjeeth Shamola
Published: November 2023

The COVID-19 pandemic has forced higher education institutions (HEIs) to re-look at their assessment strategy as learning, development, and engagement move more fluidly into the online arena. The purpose of this research was to investigate students' academic and personal perceptions of computer adaptive testing (CAT) in higher education to understand students’ confidence in adopting CAT. Using a quantitative descriptive research design, an online questionnaire was administered to students at private and public HEIs in South Africa, with 600 respondents. The study found that the students were comfortable engaging in online learning and expressed positive perceptions of adopting CAT, with most respondents recommending it for implementation. Students believe that CAT allowed for more productive interaction with material which meets their needs and learning preferences without feeling overburdened. The findings of the study provide HEIs with valuable information on key managerial implications to ensure the successful adoption and implementation of CAT.
Occurrence, quantification and removal of triclosan in wastewater of Umbogintwini Industrial Complex in KwaMakhutha, South Africa
Authors: Mhlongo Siyabonga A. , Sibali Linda L. , Ndibewu Peter P.
Published: November 2023

We report on the detection of an organic pollutant mostly found in local streams and wastewater treatment plants, specifically on triclosan detected in the Umbogintwini Industrial Complex (UIC), located on the south coast of Durban, KwaZulu-Natal in South Africa. Triclosan was successfully extracted from effluent samples using molecularly imprinted membrane adsorbents (MIMs) before quantification and removal using high-performance liquid chromatography (HPLC). This was done through fabrication of a polyvinylidene fluoride polymer using selective microparticles and molecularly imprinted polymers by means of phase inversion and an immersion precipitation method which results in enhanced hydrophilicity and membrane performance. The optimisation of experimental parameters – i.e. contact time and sample size – was performed through different stages of analysis. The synthesised MIMs exhibited an outstanding adsorption efficiency of 97% for triclosan in relation to those of non-imprinted membranes (NIMs) and pristine membranes at 92% and 88%, respectively. The analytical method employed had limits of detection and quantification of 0.21 and 0.69 parts per billion (ppb or μg/L) in wastewater effluent, respectively. The obtained efficiency results show great potential for future use of membrane and molecular imprinting technology, and that MIMs can be adopted as adsorbents for water treatment. The fast and highly selective methodology presented in this work could also be employed for the examination of persistent organic pollutants in the future to combat water scarcity in South Africa.
Significance:
The key finding of this work is the incorporation of molecularly imprinted polymers with a membrane adsorbent to improve the performance of the membrane. An unexpected finding was the existence of pollutants like triclosan in water within the boundaries of the KwaMakhutha community, near the human settlement. Among the MIMs, NIMs and bare membranes, higher removal efficiencies were displayed by the synthesised MIMs against the discovered pollutants. This work could open doors for advanced research in the community.

Published: November 2023

Omental Infarction (OI) is a rare condition that can mimic common causes of acute abdominal pain, primarily affecting individuals aged 40 to 50, with a male predominance. Imaging techniques like ultrasound and computed tomography aid in diagnosis. Treatment options range from conservative management to surgery, depending on severity and complications. OI often leads to right-sided abdominal pain in 90% of cases, with histological features including focal necrosis and fibroblastic reactions. Acute appendicitis is a common cause of acute abdominal conditions, especially in children and adolescents. Having a patient simultaneously presenting with acute appendicitis and omental infarction is extremely rare, with only three cases reported in the literature to date to our knowledge. We present the case of a 32-year-old male, a heavy smoker, who presented with epigastric pain and vomiting. Initial clinical suspicion was a perforated ulcer, but imaging revealed swollen appendicitis with adjacent fat stranding and evidence of epiploic infarction near the stomach. Laparoscopic surgery confirmed the diagnosis of acute appendicitis, with an appendectomy performed and identification of the infarcted omentum, which was preserved. After the operation, the patient had a successful recovery and was discharged on the second postoperative day. This case firstly emphasizes the rarity of the association between acute appendicitis and omental infarction in the same patient and underscores the importance of considering Omental Infarction (OI) in the differential diagnosis of acute abdominal pain. Imaging plays a crucial role in accurate diagnosis, and a high degree of suspicion and prompt diagnosis are crucial for optimal patient outcomes.
Sonographic appearances of the kidneys and correlation with CD4 count and viral load in adult HIV/AIDS patients in a rural-based infectious disease hospital in sub-saharan Africa

Published: November 2023

Background: The management of HIV infection is often challenging as it can affect every organ in the body including the kidneys. Determination of the Resistivity Indices (RI) of the intra-renal arteries is an emerging non-invasive tool that could predict renal disease. Aims & objectives: To determine the renal volume, parenchymal pattern, as well as the RI of the intra-renal arteries by Doppler ultrasonography in adult HIV/AIDS patients and correlate findings with CD4 count, viral load and serum creatinine. Materials & methods: This is a comparative cross-sectional descriptive study that involved sonographic assessment of the renal dimensions, parenchymal echogenicity, and Doppler velocimetry of the segmental intra-renal arteries in 100 apparently healthy confirmed HIV-seronegative control subjects and an equal number of confirmed HIV-seropositive adult patients at Retroviral (RV) clinic of our hospital. A Doppler ultrasound machine with a 3.5MHz Curvilinear probe was used. Data analysis: Data obtained was analyzed and presented as means which were compared using Student’s t - test, and p values < 0.05 at 95% intervals were considered significant. Pearson’s correlation coefficient was used to assess correlation. Results: The renal volumes were larger in the HIV/AIDS subjects (right: 125.94 ± 34.02 cm3 and left: 138.99 ± 33.29cm3) than in controls (p = < 0.01) with the left also larger than the right in both HIV/AIDS and control subjects (p = < 0.01, < 0.01) respectively. There were significantly more individuals with abnormal renal echogenicity in the HIV/AIDS subjects than in the controls. The RI was significantly greater in the HIV/AIDS than in control subjects. Both renal volumes showed a weak negative correlation with CD4, viral load, and serum creatinine which was not statistically significant. There was a statistically significant weak negative correlation between renal echogenicity and CD4 but a positive correlation with viral load and serum creatinine. RI showed weak negative correlations with serum creatinine and weak positive correlations with CD4 count. Conclusion: There is a significant difference in renal volume, echogenicity, and RI in HIV/AIDS patients compared to the controls. Renal echogenicity is a better predictor of serum creatinine levels than renal volume and RI. Thus, renal volume and RI do not provide sufficient correlation to be used as a means of monitoring HIV/AIDS patients with renal impairment.

What can we learn from Bonhoeffer concerning the churches facing Palestinian suffering?
Authors: Duchrow Ulrich
Published: November 2023

Dietrich Bonhoeffer’s essay on “The Church and the Jewish Question” (1933) inspired already two ecumenical processes. The first one was the decision of the Lutheran World Federation (LWF) in 1977 declaring apartheid a status confessionis, the second was the call of the World Alliance of Reformed Churches (WARC) to engage in a processus confessionis “regarding economic injustice and ecological destruction” (1997). This led the LWF (2003), the WARC (2004) and also the World Council of Churches (WCC in 2013) to formally reject imperial neoliberal capitalism. Now it inspires the church actions against the state of Israel, depriving the Palestinians of their civil and political rights and the justification of this by misusing the Bible in (Christian) Zionism. This amounts to apartheid according to all relevant human rights organizations and the UN. There are important consequences for Christian-Jewish relations in Germany and the West today. After Western antisemitism and the horrific genocide by German Nazis against the Jewish people it was extremely necessary to overcome this past by intensive Christian-Jewish dialogue. However this has become a deal to silence critique of Israel’s constant violations of international law and human rights, as pointed out by the Jewish liberation theologian Marc Ellis. In order to overcome this a theology of land respectful of human rights is needed. Churches are being called to a process of study and discernment leading to action. A special responsibility lies with the churches in Germany and the USA because their governments must link their cooperation with the State of Israel to international law and human rights.
Raised in newness of life
Authors: Dodson Chris
Published: November 2023

In the last days of World War II, Dietrich Bonhoeffer struggled to understand how the church was meant to live faithful to Christ in this catastrophic setting. In a letter written for his godson’s baptism, he connects themes of religionlessness and the sacraments – in particular, baptism, confession, and the Eucharist – to explore what this faithfulness might look like. In five reflections, Bonhoeffer considers and the legacy of Germany and his generation and confesses their sins and failures in hopes of creating an opportunity for the coming generation to begin their life of faith with a religionless disposition more fitting to the time and the calling of Christ. Concluding with examples of how some in subsequent generations have lived in a manner reflective of Bonhoeffer’s hopes, this article asserts that Bonhoeffer’s vision of a life transformed through reception of the sacraments remains a compelling and honest vision for Christian fidelity to both God and the Christian’s worldly context.
EVALUATION OF ECOSYSTEM SERVICES OF THE CITY OF CHERNIHIV WITH THE BEGINNING OF THE FULL-SCALE INVASION OF RUSSIA ON THE TERRITORY OF UKRAINE
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Zapototskyi Sergii , Holub Yuliia ,   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine
Published: November 2023

Purpose. The purpose of the article is to analyze the ecosystem services of the city of Chernihiv after the beginning of the full-scale invasion of the Russian Federation and to assess the consequences of military actions for the urban space and ecosystem. Methodology. During the writing of the article, the method of analysis and synthesis, analytical, systematic and graphic were used. The informational basis of the study is the scientific work of Ukrainian and foreign scientists, as well as the authors' own observations and memories related to the first days of the Russian-Ukrainian war and the damage that was caused to the environment. Results. The impact of military operations on the disruption of ecosystem elements has been studied. Using the example of the city of Chernihiv, the importance of component ecosystem services and the need to preserve them to ensure the balanced development of the city's territory and improve the quality of life of the population is revealed. The main changes and consequences of the Russian aggression, which affected the state of atmospheric air, river systems, soils, and forest areas, are outlined. One of the main environmental problems of the city is analyzed - the accumulation of garbage and the handling of solid household waste. The ecological potential as a vector of the work of the new City Development Concept, which began to be developed immediately after the end of active hostilities in Chernihiv, was considered. Scientific novelty. Chernihiv is one of the largest cities in the north of Ukraine, which Russian troops have been trying to capture since February 24, 2022. Occupying a convenient geographical position determined by the proximity to the capital of the country, it is of strategic importance for the state. In addition, Chernihiv has unique historical-cultural and natural-recreational resources that require protection and appropriate treatment on the part of the population. Russian aggression caused the destruction not only of infrastructure facilities, enterprises, and houses, but also caused damage to the environment, which in some places has catastrophic consequences. Thus, the study of the elements of the ecosystem, the study of the city's ecological problems, and the receipt of ecosystem services require additional attention from scientists, especially after active hostilities. Practical significance. The practical significance of the article is determined by the possibility of using the research results during educational activities to increase the level of environmental culture and education of the population.

Published: November 2023

Aim: to study the role of the hemostatic system in pretem delivery in pregnant women who have had COVID-19 in the gestation period from 14 to 16 weeks.

Materials and Methods. A prospective single-center observational study was conducted by enrolling 63 pregnant women with verified COVID-19 at 14–16 weeks of gestation. The main group consisted of 37 patients with preterm birth (PB), comparison group – 26 patients labour activity that occurred at least at gestational age of 37 weeks. Clinical and anamnestic data and dynamic changes in fibrinogen and D-dimer level, activity of tissue factor (TF), tissue factor pathway inhibitor (TFPI), plasminogen activator inhibitor-1 (PAI-1), tissue plasminogen activator (t-PA), urokinase plasminogen activator (u-PA) were analyzed; thrombin generation assay (TGA) was performed.

Results. It was found that severity of COVID-19 infection did not determine the timing of delivery that depended on patient comorbid condition. All PB observations (37 out of 63, 58.7 %) were caused by decompensated placental function manifested by acute obstetrical complications: increasing intrauterine fetal hypoxia (64.9 %) along with intrauterine growth retardation (51.4 %), severe preeclampsia (13.5 %) and premature abruption of the normally located placenta (5.0 %). In both study groups, COVID-19 experienced at 14–16 weeks of pregnancy was associated with coagulation and fibrinolytic imbalances. At the same time, at least 6 weeks post-COVID-19 infection, patients with PB had higher level of the “Peak thrombin” vs. comparison group (3050 vs. 2527 pmol/L; p = 0.0433). Also, patients with term vs. preterm delivery had TF activity decreased significantly: by 47.1% and 28.1%, respectively (p = 0.0546). Patients in preterm delivery group were characterized by fibrinolytic imbalance. At the first time point, suppressed fibrinolysis (PAI-1 level – 18.4 vs. 12.5 ng/ml in the comparison group; p = 0.0209) was concomitant with elevated level of u-PA (1.5 vs. 0.55 ng/ml in comparison group, p = 0.0015), which suggests a potential prolonged immunoinflammatory response in patients with PB. Magnitude of fibrinogen concentration and D-dimer level during post-COVID-19 follow-up study was within the reference values specific to gestational age.

Conclusion. A significant increase in coagulation potential was found and verified by elevated activity of tissue factor and potential to thrombin generation in COVID-19 convalescent patients. In the case of preterm delivery, there was an imbalance in fibrinolysis system revealed by decreased blood fibrinolytic activity elevating along with increasing gestational age.
Trauma-Informed Yoga Teacher Training: Impact on Incarcerated Men’s Wellness
Authors: Harner Holly , Henderer Anna , Murphy Nancy
Published: November 2023

In late 2021, the United States had a total of 1.2 million individuals confined in state and federal prisons, with approximately 1.1 million of these people being men. Although existing research provides evidence that engaging in yoga programs within prison settings can enhance the well-being of incarcerated individuals, with several studies supporting this claim, knowledge regarding the specific effects of participating in a yoga teacher training program during confinement is still lacking. The purpose of the present investigation was to evaluate the effect of completing a prison-based 200-hour trauma-sensitive yoga teacher training program on the perceived physical, mental, social, and spiritual wellness of men in prison. We hypothesized that men who successfully completed the training program would report notable improvements in all four dimensions of wellness. Focus groups, participant workbook reviews, and demographic surveys were used to understand how participation in yoga teacher training influenced men’s perceived wellness. Participants identified a variety of wellness gains associated with yoga teacher training. These gains have the potential to contribute to improved individual health, improved relationships with others, and safer communities.

This study evaluated the effects of sowing dates and maturation group of soybean on soybean-corn succession in the Southwestern of Paraná state, Brazil, at the 2016/17 and 2017/18 growing season. Experiment was laid out as a randomized complete block design in a 3×3 factorial scheme with three replications, being factor A three soybean cultivars with different maturation group and factor B three soybean sowing dates. Corn sowing periods (nine at total) was a consequence of the soybean harvest date. Soybean cultivars with a maturation cycle between 5.1 and 5.3 sowed in mid-September resulted in better corn performance, but worse technical feasibility for the soybean-maize succession in relation to its sowing on the beginning of October, which results in better total grain yield. Soybean cultivar with maturity group 6.0 was a good option for the mid-September sowing. Soybean sowing in mid-October did not increase its yield and reduce the corn yield.

La concretización de los derechos humanos fundamentales: positivismo, interpretación y seguridad jurídica
Authors: Jiménez Serrano Pablo
Published: November 2023

Este artículo tiene como objetivo discutir los factores que limitan la efectividad y concretización de los derechos humanos fundamentales en las sociedades brasileña y latinoamericanas. Por medio de una investigación doctrinal e histórico-realista (empírica), se caracterizan los obstáculos que impiden la anhelada concretización. La metodología utilizada contempla el método deductivo, aplicado en la investigación bibliográfica, filosófica y normativa, brasileña y extranjera, teniendo como marco teórico, entre otros, los trabajos “El Derecho como texto: cuatro estudios de teoría comunicacional del derecho”, de Gregorio Robles, “Curso de filosofía jurídica”, de Pablo Jiménez Serrano y “La era de los derechos”, de Norberto Bobbio. Teniendo como base estos trabajos, se discute la importancia y las perspectivas de una teoría comunicacional del derecho y los límites que el texto legal impone a la implementación, debido a la falta de conocimiento o mal uso de las técnicas legislativas. También se discute el concepto, el significado y el alcance de los conceptos operacionales utilizados y relacionados a la concretización de los derechos humanos fundamentales. Se concluye que la responsabilidad de la concretización y efectividad de los derechos es de naturaleza estatal, gubernamental y social, siendo la solidaridad y la convivencia social los principios rectores de este proceso, más allá de los intereses económicos y políticos partidarios.

Published: November 2023

Trata-se de uma pesquisa realizada a partir de uma perspectiva psicossocial, que buscou relacionar a satisfação corporal de jovens adultos com suas práticas corporais e o uso que fazem de redes sociais virtuais. Participaram do estudo 207 jovens, que responderam um questionário online autoaplicado, cujas respostas foram tratadas com estatística descritiva e inferencial. Os resultados indicaram que a satisfação corporal é mais presente entre os praticantes de atividades físicas, e, em contrapartida, observou-se menor satisfação corporal entre os participantes mais aderentes a dietas e cirurgias plásticas estéticas. Algumas práticas corporais encontraram associação estatística significativa com o uso das redes sociais virtuais: praticantes de atividade física as acessam por menor tempo diário e visualizam conteúdos alusivos à saúde; dietas e cirurgias plásticas estão associadas ao maior acesso a conteúdos de influenciadores digitais. Assim, a satisfação corporal e a forma como jovens utilizam redes sociais virtuais podem ter influência sobre suas práticas corporais.

Serum Interleukin-6 in Schizophrenia: Associations with Clinical and Sociodemographic Characteristics
Authors: Zhilyaeva Tatyana V. , Rukavishnikov Grigory V. , Manakova Elvira A. , Mazo Galina E.
Published: November 2023

BACKGROUND:Recentlyasignificant part of schizophrenia studies have been focused on the role of cytokines, especially interleukin-6 (IL-6). Some authors have suggestedapathogenetic role for IL-6 in schizophrenia and concluded that therapy that centers on suppressing IL-6 activity may prove beneficial for certain categories of patients with the disorder. However, many questions about whether the changes in IL-6 levels in schizophrenia are primary, related to symptoms or caused by therapy, are concomitant metabolic disorders, are related to smoking or other secondary factors remain unanswered.
AIM:To assess the level of serum IL-6 in patients with schizophrenia in comparison with healthy controls, as well as to study its association with clinical and socio-demographic characteristics.
METHODS:Some 125 patients with schizophrenia and 95 healthy volunteers were examined.Theevaluation of IL-6 was performed by enzyme immunoassay. All patients were assessed using standardized psychometric instruments. Information from patient medical records on the course of the disease and treatment wasanalyzed.
RESULTS:Thelevel of IL-6 was significantly higher in the patients than in the healthy volunteers (z=2.58;p=0.0099), but among men the difference between the patients and volunteers was not significant. Statistically significant correlations were found between the level of serum IL-6 and the severity of the cognitive impairment of patients: (auditory [ρ=–0.31;p=0.00063] and working memory [ρ=−0.25;p=0.0065], hand-eye coordination [ρ=−0.29;p=0.0011], verbal fluency [ρ=−0.28;p=0.0019] and problem-solving capacity [ρ=−0.22;p=0.013]), total severity of schizophrenia symptoms (PANSS, ρ=0.22;p=0.016), PANSS positive subscale (ρ=0.18;p=0.048), and the age of manifestation (ρ=0.20;p=0.025) and disease duration (ρ=0.18;p=0.043).Thelevel of IL-6 was the lowest in patients treated with third-generation antipsychotics, and the highest in those treated withfirst-generation antipsychotics (H=6.36;p=0.042). Moreover, in hospital patients, the level of IL-6 was significantly higher than in outpatients and inpatients hospitals (H=18.59;p=0.0001).
CONCLUSION:Thestudy confirmed that there are associations between the serum IL-6 level and schizophrenia, the age of the patient, duration of the disease and how late in one's life cycle it began manifesting itself, as well asanumber of clinical characteristics. Considering that IL-6isassociated withawide range of symptoms that are loosely controlled by antipsychotics, this biochemical marker needs to be studied to look into how closely its level tracks with an unfavorable course of schizophrenia. That would require further prospective studies.
USAGE OF BILECIK LEFKE STONE AND BENTONITE CLAY FOR PHOSPHORUS REMOVAL IN WATER
Authors: ÇANGA Betül , MERAL Ramazan , ALKAN Çayan
Published: November 2023

The rapid increase in the world population, the development of the industry, the excessive usage of fertilizers in agriculture, and the increase in detergents and chemicals used for cleaning accelerate the pollution of water resources. Conservation and recovery of damaged water resources along with the deteriorated ecosystem is of great importance for living things. An important part of water pollution in lakes and rivers is the increase in the content of nutrients. Nutrient elements, especially phosphorus, cause the transparency of water to decrease gradually. Over time, this situation, called eutrophication, causes an algae bloom and the aquatic ecosystem is disrupted. Uncontrolled discharge of wastewater containing phosphorus in high concentrations accelerates this process. These nutrients must be removed in order to maintain water quality and reduce the risk of eutrophication. The main ways of removing phosphorus from water are physical, chemical and biological methods. Among these, as an alternative to settling with chemical substances, the usage of clay (based on fixation) has an important place. In this study, different dosages of bentonite, lefke stone and ferrous sulphate heptahydrate (FeSO4.7H2O) were used in water with three different pH values (4, 7 and 10) and three different phosphorus contents (20, 40, 60 ppm). The per cent yields of the phosphorus removed with ferrous sulphate heptahydrate, lefke stone and bentonite are 72%, 57% and 39%, respectively. In addition, it was determined that the dosage of additives used should be renewed depending on the phosphorus content of the environment and that the high pH value of the environment increased the efficiency, especially in the usage of ferrous sulphate heptahydrate. In conclusion, as an alternative to the usage of chemicals, it has been revealed that lefke stone can be used for phosphorus removal in water, and its effectiveness can be further increased with further studies.

Transversus abdominis plane (TAP) block is a successful postoperative analgesia technique in laparoscopic surgeries. This study compared the analgesic efficacy of 0.25% bupivacaine and 0.375% Ropivacaine in TAP block as post-operative analgesia for upper abdomen laparoscopic surgeries.

: This randomized, double-blinded comparative study was conducted at the Dr Jeyasekharan Medical Trust and Nursing Home for 18 months. Seventy-one consenting adult patients undergoing upper abdominal laparoscopic surgeries qualifying the inclusion criteria to undergo Bilateral Subcostal TAP Block were included. The patient was labelled group A or B according to a computer-generated randomization list. TAP block was administered using 30 ml (15 ml on each side) of 0.25% bupivacaine (A) or 0.375% ropivacaine (B). Similar premedication and induction were given to all patients.

: Among 71 patients in group A, males were 5 (14.7%), and females were 29 (85.3%). In group B, males were 7 (18.9%), and female was 30 (81.1%). There is no significant difference in gender, age, and BMI between groups. The mean duration of analgesia with 0.375% ropivacaine (10.21±3.36 hrs.) was significantly higher than 0.25% bupivacaine (6.38±2.03 hrs.). In the first 24 hours postoperatively, the mean total tramadol consumption was 147.06±11.94 mg in group A and 117.57±31.11 mg in group B, which is statistically significant.

: This study concludes that 0.375% 30ml ropivacaine given as a TAP block under ultrasound guidance significantly prolonged the post-operative analgesia duration compared to 0.25% 30ml bupivacaine.

This pilot study aimed to bridge the digital divide between older and younger adults. The goal was for older people in the state to become digitally literate by engaging them in a program that provides digital devices (i.e., Apple iPads), internet connectivity (i.e., through HotSpots), and training from supervised university student mentors. This project, funded as a key policy initiative through the state's unit on aging, specifically promoted social and economic equity by targeting participants from lower‐income communities and areas hit hardest by the COVID‐19 pandemic. Our university partnered with senior/community centers to recruit and support English‐ and Spanish‐speaking adults 50 years of age and older (age range: 55‐100, M=72.3, SD=8.5). For this paper, we examined changes in technology use and digital competence from the pre‐ to the post‐survey (collected over the phone) from older participants (N=145), and we examined how the program contributed to new ways for participants to connect to community resources. Based on statistical analyses, participants improved in digital competence (pre=2.06, post=2.74), technology use (pre=1.99, post=2.70), tablet use (pre=1.53, post=4.08), and the number of purposes in which participants used technology (pre=4.09, post=5.55; p's<.01). Themes that arose from the qualitative data included feeling more capable and confident in searching out new information, now knowing where to find activities and resources, and meeting with doctors and booking health appointments. This program addressed a significant community need during the pandemic and had success working with community partners. Policies for state grants that support broadband equity, digital literacy and digital equity initiatives should utilize this research to inform their efforts to address digital inclusion needs for older adults.
Negotiating Technological Engagement: Use and Non‐Use Among Older Adults in Assisted Living
Authors: Snyder Jennifer L.
Published: November 2023

Recent research on digital inequalities has shown that some individuals, including older adults, display careful consideration when deciding to use or not use technology. The purpose of this study is to explore the relationship between aging and technology use by examining not only the types of technologies used by older adults, but also how they make decisions about that use. Using semi‐structured interviews and observations of staff members, residents, and family members of residents at a privately owned, for‐profit assisted living facility in the northeast U.S., this research offers essential insights into the relationship between older adults and technology, along with the implications of that relationship on policy recommendations surrounding technology use. First, consistent with recent trends in research, the findings of this study reveal how technology use among older adults involves a complex decision‐making process. Specifically, they navigate use and non‐use by considering their skills and needs, while also managing their limitations and fears of technology. They also employ advanced mechanisms to compensate for the missed opportunities of non‐use. Treating use as a negotiated process urges policymakers and practitioners to prioritize older adults' agency when considering the implementation of technological policy and intervention. Second, I propose an Interaction Approach of Technology Use as a more nuanced way to understand older adults' technology use as it relates to the degree of independence or dependence that occurs during that use. An interactive approach allows researchers and policymakers to consider a wider range of use when examining the relationship between older adults and technology.
