Entrepreneurship disruptions have become a pervasive and transformative force in today's global business landscape. These disruptions are characterized by the rapid and often unpredictable changes that impact the way entrepreneurs conceive, launch, and operate businesses. In the modern era, the rapid pace of technological advancement and the rise of disruptive innovations have presented a significant challenge for entrepreneurs and established businesses alike. As entrepreneurs strive to identify and leverage disruptive opportunities, they face complex issues related to market dynamics, economic instability resource allocation, and competitive pressures. Moreover, the ever-accelerating rate of disruption necessitates a deeper understanding of how entrepreneurs can effectively navigate these challenges while staying innovative and sustainable. This study seeks to identify and analyse the experiences and challenges faced by businesses in their pursuit of sustainability during this disruptive era. Data were generated via the internet, newspapers, newsletters, libraries and other documented materials pertinent to the study.  Findings revealed that there is a positive relationship between entrepreneurship disruptions and business sustainability in Nigeria. To fully harness disruptive entrepreneurship and achieve sustainability, regulatory reforms, technological advancements, changing consumer behaviour, infrastructure development, and increased access to funding are crucial. Consequently, to address these challenges and promote sustainability, it is imperative to conduct a comprehensive analysis of the experiences and challenges faced by businesses and individuals in the disruption era, businesses in Nigeria need to adopt innovative solutions, and collaborate with relevant stakeholders while keeping a close eye on regulatory changes and global trends.

Authors: Uwitonze Felix
Published: May 2024

This study examined Huguka Radio in Muhanga District in Rwanda to see how radio contributes to socio-economic development. It helped identify Huguka Radio's socio-economic benefits and problems. This research also helped the researcher graduate in Masters in Development Studies. The campaign targeted 250 Huguka Radio listeners, journalists, managers, government officials, civil society organizations (CSOs), and media advocates. Slovin's formula determined a sample size of 75 applicants using purposive or judgmental sampling and simple random sampling. Surveys and interviews were utilised to obtain data from Huguka Radio listeners, staff, government officials, civil society organisations, and media advocates. After discussing the research instruments with the supervisor, the researcher confirmed that the questions and substance were valid. To assess reliability, respondents' answers were tested again. Using percentages and frequencies, SPSS descriptive statistics analysed quantitative data. To analyse qualitative data, content analysis was performed. The poll found that 95.2% of respondents thought that radio helps Rwanda's economy, while 92.1% said Huguka Radio does. In particular, 93.3% of respondents believed Huguka Radio promotes agriculture and farming, 94.9 % human rights, and 84.7 % health. The research also revealed that Huguka Radio promotes socio-economic development through rural forums, accessible language, and community debates. Due to financial constraints, Huguka Radio struggled to promote socioeconomic development. Some respondents noted that this issue limits equipment, professional journalists to work on contract, radio journalists' consistency, and time and area to reach people, especially in rural areas where many Rwandans live. Huguka Radio should collaborate with other broadcasters and keep engaging socio-economic development partners. After this investigation, the researcher suggested other research subjects, including Financial inability of radio and socio-economic growth in Rwanda; and cooperation with government institutions.

IMPACT OF TREATMENT OF DIABETIC MACULAR EDEMA ON VISUAL IMPAIRMENT IN PEOPLE WITH TYPE 2 DIABETES MELLITUS: A COMPREHENSIVE SYSTEMATIC REVIEW AND METAAANALYSIST STUDY
Authors: Yovita  , Setiohadji Bambang
Published: May 2024

Background: Diabetic retinopathy (DR) and diabetic macular edema (DME) are among the most significant and disabling chronic complications of diabetes mellitus. DME is an important cause of severe vision loss in type 2 diabetes. Hyperpermeability of retinal blood vessels and subsequent formation of edema and hard exudates are the key clinical features.
Method: This systematic review and meta-analysis, conducted following PRISMA guidelines and employing the PICO format, aim to explore about impact of treatment of diabetic macular edema on visual impairment in people with type 2 diabetes mellitus, focusing on treatment, complications, and prognosis. Inclusion criteria encompass diverse study designs (RCTs, observational, quasi-experimental, and case-control studies) investigating impact of treatment of diabetic macular edema on visual impairment in people with type 2 diabetes mellitus among treatment, complications, and prognosis, while exclusion criteria filter out studies lacking relevance to impact of treatment of diabetic macular edema on visual impairment in people with type 2 diabetes mellitus.
Result: After conducting three levels of screening, the results of our search in Pubmed get 6 articles, whereas the results of our search on SageJournal get 42 articles, on Lancet 21, and on Scient direct get 60 articles. Records remove before screening are 91, so we get 78 articles for screening. After we screened based on record exclude, we compiled a total of 10 papers. We included four research that met the criteria.  
Conclusion: There is a particularly robust response to anti-VEGF therapy in both groups when glycemic control is optimized, highlighting the critical importance of communication between the physicians managing the DME and those managing systemic diabetes control. Improving our understanding of the factors that contribute to anti-VEGF response for DME therapy may help to enhance DME treatment outcomes, particularly through the concerted coordinated efforts of the treating retina specialist and the endocrinologist or primary care physician.

Published: May 2024

Introdução: A Doença Renal Crônica (DRC) é um problema de saúde pública mundial, afetando de 8-16% da população mundial e com prevalência em ascensão. O diagnóstico da DRC compreende avaliação da albuminúria, níveis séricos de creatinina e o cálculo da Taxa de Filtração Glomerular (TFG). Dentre os fatores de risco ao desenvolvimento da DRC, destaca-se a Hipertensão Arterial Sistêmica (HAS) e Diabetes Mellitus tipo 2 (DM2). Portanto, avaliar pessoas em risco, que desconhecem sua saúde renal, é vital para melhorar o prognóstico e realizar os encaminhamentos conforme recomendações do Sistema Único de Saúde (SUS). Objetivo: Determinar a prevalência de DRC em indivíduos com hipertensão e/ou DM2. Métodos: Trata-se de um estudo descritivo, observacional e transversal, realizado em um ambulatório de uma faculdade de medicina em Belo Horizonte. Foi avaliada e classificada a função renal de hipertensos e diabéticos, totalizando 97 pacientes. Resultados: Dos participantes, 48% apresentaram TFG G1 (> 90 ml/min/1,73m²), 27% G2 (60-89 ml/min/1,73m²), 13% G3a (45-59 ml/min/1,73m²), 9,3% G3b (30-44 ml/min/1,73m²) e 2,1% G4 (15-29 ml/min/1,73m²). Conclusão: Do total, 52% apresentaram redução na TFG e 2,1% uma queda grave. O estudo está em consonância com pesquisas anteriores que indicam o DM2 e a hipertensão como fatores de risco para a DRC. Embora limitado pelo tamanho da amostra, o estudo destaca a necessidade da avaliação da função renal em pacientes com doenças crônicas. Estudos adicionais podem revelar mais associações entre comorbidades comuns e doenças renais, aprimorando, em última análise, o cuidado ao paciente.

Published: May 2024

Many diseases, esp. the chronic diseases, are incurable. That means that for a long time, doctors will be palliating the symptoms and when time comes, they would take responsibility for caring for dying patients. They shouldtherefore prepare themselves to have discussions with patients and their families, manage their symptoms, support their families, diagnose dying, manage symptoms at the end of life, work in multi-disciplinary team and makedecisions about withholding and withdrawing treatments to void patients’ burden.Text: Although all doctors work hard to cure ailments and save lives, dying from incurable diseases remain abasic fact of life. Despite the advent of modern treatments, most diseases in textbook remain incurable althoughthese are, at best, controllable. Examples include Ischaemic Heart disease, Heart failure, Renal failure and cancer. There are diseases which cause immense burden on patients and are therefore requiring long-term symptom management and nursing support.In this view, managing terminal phase of incurable diseases and death itself remains a healthcare professional’sresponsibility. In industrialized world and some developing countries like India, Palliative care has taken up thatrole but it is identified that providing palliative care is responsibility of all healthcare professionals (1).

Songs and singing in school: Danish school singing between tangible and intangible cultural heritage
For centuries, singing has played a vital role in elementary schools in Denmark. During the 20th Century, singing’s significance – in Denmark as well as elsewhere in Europe – was gradually downplayed, and singing was reduced from an independent subject and an overarching activity to a subdiscipline under the broader subject of “Mus­ic”. In the 2020’s a renewed interest in communal singing is surging in Denmark; this also entails an increasing focus on the benefits of school singing. Political and societal discourse is fraught with wishes of revitalizing singing culture in schools. However, the arguments to support such wishes are quite different in nature, some­times lead­ing to misconceptions. This article aims to show that arguments for school singing fall within a continuum between two poles: In one end of the continuum, singing is valued as a way to preserve a culturally valued repertoire of songs, and in the other end, singing is val­ued as a beneficial activity regardless of what is being sung. The purpose of the article is thus to establish a conceptual distinction that has hitherto been unclear, underscored by the inability of the Danish language to discriminate clearly between “song” and “singing”. To support our case, we mobilize the conceptual pair of tangible and intangible cultural heritage, arguing that these can be mapped on to the distinction between school singing as preservation of songs vs. as an activity in its own right. Further, we trace the occurrence and connotation of the word “song” in Danish public newspapers from the late 18th Century to the 2020’s, showing that the term does indeed fluctuate between connotations of tangible and intangible cultural heritage throughout the period.

Published: May 2024

Constructing Type-II heterostructure is an effective scheme to tailor the electronic structure and improve the application performance. Motivated by recently successful syntheses of Mg(OH)2 and GaS monolayers, we investigate the stability, electronic, and optical properties of GaS/Mg(OH)2 heterostructure by using the density functional theory method. The calculated results show that GaS/Mg(OH)2 heterostructure is easily constructed due to its small lattice mismatch, negative binding energy, and thermodynamic stability. Compared with monolayer materials, the GaS/Mg(OH)2 heterostructure has a band gap that effectively decreases to 2.021 eV and has Type-II band structure, facilitating the spatial separation of photo-generated carriers where electrons are localized in the GaS and holes reside in the Mg(OH)2 monolayers. The built-in electric field induced by the interlayer charge transfer points from GaS to Mg(OH)2 monolayer, which can further improve the separation and suppress the recombination of electron-hole pairs. Under the biaxial strain, the valance band maximum and conduction band minimum of GaS/Mg(OH)2 heterostructure shift in the downward direction to different extents, resulting in obvious change of band gap, with the change reaching about 0.5 eV. Furthermore, the band structure of GaS/Mg(OH)2 heterostructure can be transformed from indirect band gap semiconductor into direct band gap semiconductor under the tensile strain, while GaS/Mg(OH)2 heterostructure maintains Type-II band structure. Additionally, the band edge positions of GaS/Mg(OH)2 heterostructure can also be effectively adjusted to cross the redox potentials of water decomposition at pH = 0–7. The light absorption spectra show that GaS/Mg(OH)2 heterostructure has stronger light absorption capability than the constituent monolayers. Especially, the light absorption has an obvious redshift phenomenon at a tensile strain of 3%. These findings indicate that the GaS/Mg(OH)2 heterostructure has a wide range of applications in the field of optoelectronics due to the tunable electronic properties, and also provides some valuable insights for future research.

Authors: Khuong Nguyen Quoc , Nhat Nguyen Minh , Thu Le Thi My , Thuc Le Vinh
Published: May 2024

The aim of the current study was to assess the potency of the exopolymeric substances (EPS)-secreting purple non-sulfur bacteria (PNSB) on rice plants on acidic salt-affected soil under greenhouse conditions. A two-factor experiment was conducted following a completely randomized block design. The first factor was the salinity of the irrigation, and the other factor was the application of the EPS producing PNSB (Luteovulum sphaeroides EPS18, EPS37, and EPS54), with four replicates. The result illustrated that irrigation of salt water at 3–4‰ resulted in an increase in the Na+ accumulation in soil, resulting in a lower rice grain yield by 12.9–22.2% in comparison with the 0‰ salinity case. Supplying the mixture of L. sphaeroides EPS18, EPS37, and EPS54 increased pH by 0.13, NH4+ by 2.30 mg NH4+ kg−1, and available P by 8.80 mg P kg−1, and decreased Na+ by 0.348 meq Na+ 100 g−1, resulting in improvements in N, P, and K uptake and reductions in Na uptake, in comparison with the treatment without bacteria. Thus, the treatments supplied with the mixture of L. sphaeroides EPS18, EPS37, and EPS54 resulted in greater yield by 27.7% than the control treatment.

Purpose

The aim of this study was to assess the reliability and validity of the My Jump 2® app in measuring jump height, flight time, and peak power among elite women beach volleyball players on sand surfaces.

Methods

Eleven elite female beach volleyball players (aged 23.6 ± 6.2 years; weight 66.3 ± 5.8 kg; height 174.4 ± 5.8 cm; with 8.4 ± 4.8 years of professional experience) participated in this study. Each player performed six countermovement jumps in a wooden box filled with sand on a force platform while simultaneously recording a video for subsequent analysis using the My Jump 2® app.

Results

We found excellent agreement for flight time, jump height and peak power between observers (ICC = 0.92, 0.91 and 0.97, respectively). No significant differences between force platform and My Jump 2® app were detected in the values obtained for the three variables (P > 0.05). For the force platform and the My Jump 2® app, we found a good agreement measuring jump height and flight time (ICC = 0.85 and 0.85, respectively). However, we only found a moderate agreement for peak power (ICC = 0.64). The difference in jump height showed a limit of agreement between −4.10 and 4.74 cm in Bland-Altman, indicating a high level of agreement between the two measurement tools.

Conclusion

Based on our findings, the My Jump 2® app reveals a valid tool for measuring jump height and flight time of CMJ on sand surfaces. However, more caution is needed when measuring peak power.

Authors: Madkour Noha Abdelfattah Ahmed
Published: May 2024

Introduction: Diffusion can efficiently detect infratentorial and brainstem infarctions. Fluid-attenuation Inversion Recovery (FLAIR) is a widely used Magnetic Resonance Imaging (MRI) technique for the segmentation of brain lesions and strokes. Aim: To investigate the sensitivity of the Lesion Prediction Algorithm (LPA) within the Lesion Segmentation Tool (LST) in the automated segmentation of acute and subacute brainstem infarctions. Materials and Methods: This study was a retrospective diagnostic accuracy study where 24 patients with brainstem infarctions were referred from the Emergency Department to the Department of Radiodiagnosis at Kasr Alainy Hospital, Cairo University, Egypt. The study was conducted from September 2016 to June 2023. It included 24 patients (14 males and 10 females) with acute and subacute brainstem infarctions. MRI of the brain and diffusion were performed on all patients. Automated segmentation of brainstem infarctions using FLAIR was conducted in all cases. Manual and segmented volumes of brainstem infarctions were calculated. Sensitivity and accuracy of the LPA within the LST in automated segmentation of acute and subacute brainstem infarctions were evaluated. Pearson correlation was used to correlate volumes of White Matter Lesion (WML) burden in patients with brainstem infarctions and patients’ age. Results: The mean age of the participants was 51.75±11.95 years. The sensitivity of the LPA in automated segmentation of acute and subacute brainstem infarctions was 63.6% and 76.9%, respectively. An insignificant correlation (r=0.08; p-value=0.68) between the volumes of WML burden in patients with brainstem infarctions and patients’ age was noted. Conclusion: The sensitivity of the automated method in the segmentation of subacute brainstem infarctions was higher than that in acute brainstem infarctions.

Mucocele of the appendix is a rare condition caused by mucus accumulation due to a blocked appendix resulting from inflammation, infection, or faecal matter blockage. It presents as lower abdominal pain, vomiting, nausea, abdominal mass, and distension. It is more common in individuals over 50 years old and is more prevalent in the elderly. Mucocele can be differentiated into mucinous cystadenocarcinoma, mucosal hyperplasia, and mucinous cystadenoma. It is often diagnosed incidentally during radiological, laparoscopic, or surgical interventions. Ultrasound and computed tomography imaging techniques are useful in screening and diagnosing appendiceal mucocele, as they can detect a cystic mass or soft tissue mass and differentiate between a mucocele and other neoplasms. Most cases are reported in older individuals, with few in young adults. In the present case report, the authors present a case of a 34-year-old female with a history of occasional abdominal pain. On investigation, it was found to be an inflamed appendix with a mass in the right iliac fossa for which the patient underwent appendectomy. Due to the involvement of the right adnexa with tubo-ovarian complex and omentum, the present case presents a unique manifestation of an appendix mucocele.

Introduction: Bacterial Meningitis (BM) is a serious health problem worldwide with high mortality and permanent longterm neurological sequelae. Cerebrospinal Fluid (CSF) analysis is the cornerstone for diagnosing BM, but the lack of specificity creates a difficult clinical scenario for initiating proper treatment. Empiric antibiotic use in patients with suspected meningitis at primary care settings decreases the yield of CSF culture and alters CSF cytological and biochemical findings, making it further difficult to diagnose BM. To overcome this difficulty, there is a need for other biochemical markers with higher sensitivity and specificity. Aim: To determine the diagnostic sensitivity and specificity of Procalcitonin (PCT) in serum and CSF in patients with BM and compare its diagnostic accuracy in both sample types. Materials and Methods: A cross-sectional study was conducted in the Department of Internal Medicine at a tertiary care centre in eastern India from September 2018 to August 2020. A total of 82 adult patients with meningitis were recruited as per the protocol, and CSF analysis was done along with estimation of PCT in serum and CSF. Receiver Operating Characteristics (ROC) curve analysis of serum and CSF PCT was used to determine sensitivity and specificity with a 95% confidence interval. Results: Out of the 82 patients recruited, 30 (36.6%) had BM. CSF PCT with a cut-off value of >0.45 ng/mL had a sensitivity of 86.7% and specificity of 92.3%. The sensitivity of serum PCT with a cut-off value of >0.6 ng/mL was 83.3%, and specificity was 86.5%. There was no statistically significant difference in sensitivity and specificity between CSF and serum PCT in patients with BM (p-value=0.7988). Conclusion: Both serum and CSF PCT were found to have high sensitivity and specificity as markers for diagnosing BM without any statistically significant difference between them.

The practice of artisanal refining of crude oil remains rampant within the Niger Delta region of Nigeria with consequent pollution and destruction of the environment as well as exposure of the human population to various pollutants known to cause health problems. It was thus necessary to conduct this study to assess the quality of water and air in communities where artisanal refining of crude oil is carried out in Ekeremor, Bayelsa state, Nigeria. This was a comparative cross-sectional study that was conducted in Peretorugbene community in Ekeremor Local Government Area of Bayelsa state. Water samples from five points (L1-L5) in the study site and one control site (LX were obtained and assessed. Also, air quality assessments were conducted and results were comparatively assessed for significant differences between test and control sites. Results revealed that the water samples from the third sampling site (L3) had the highest levels of chromium of 0.100±0.055, while the first sampling site (L1) had the highest levels of lead of 5.225±0.687. Heavy metals’ concentrations from the water samples obtained from the artisanal refining sites significantly differed from the concentration of the samples from the non-artisanal refining site (p-value: 0.006 [for chromium], p-value: <0.001 [for lead]). Assessment of the concentration of noxious gases in the air at these two differing sites revealed that the carbon monoxide (3.110±0.160), nitrogen oxides (2.870±0.212), and sulfur oxides (2.557±0.105) from the first sampling site (L1) were the highest, and carbon monoxide and nitrous oxides concentration at the non-artisanal refining site was significantly lower from the concentrations at all the artisanal refining sites (p-value: <0.001). Also, the turbidity, temperature, and salinity of the water samples exceeded the allowable standard limits, alongside the lead, cadmium and mercury levels. In this study, it was thus concluded that the turbidity, temperature, and salinity of the water samples exceeded the allowable standard limits, while the conductivity, and total dissolved solids (TDS) in the water samples were below the acceptable standards. Also, the assessed air quality parameters were found to exceed the laid down allowable limits. It was recommended that stakeholders at the federal level of government should strengthen and enforce regulations specifically targeting artisanal refining activities in order to control and monitor their environmental impact.

Aim: The present study analysed the presence of antimicrobial resistance organisms and genes in the final effluent from STPs of hospitals.
Study Area and Sampling: Samples for microbiological analysis were collected from two different hospitals in Trivandrum City and carried out further microbiological analysis.
Methodology: In this study, MDRB (Multi Drug Resiatant Bacteria) were detected from the hospital effluent samples collected from two hospitals. Antibiotic susceptibility analysis showed that the 90% screened organisms was resistant to different antibiotics -Tetracycline (30µg), Amikacin (30µg), Gentamycin (10µg), Ciprofloxacin (5µg), Colistin (10µg) and Amoxicillin (30µg)). Metagenomic surveillance of effluent helped to assess the efficacy of STPs, at the same time assessing the local clinical antibiotic resistance condition by detection of the presence of antimicrobial resistance towards antibiotics and their  genes (ARGs) in the hospital effluent.
Results: In this study, a total of 3 antibiotic resistant bacterial strains obtained from hospital STP effluent were identified by16S rRNA sequence analysis. The sequences of E.coli, Klebsiella and Enterobacter were submitted in Genbank with accession number MT784125, OM978270 andMN437586 respectively.The final effluent from Hospital 1 showed100% resistance to Tetracycline and 86% resistance to Amoxicillin followed by sensitivity 28%, 22%, 18% and 10% respectively to Ciprofloxacin, Gentamycin, Amikacin and Colistin. The bacterial strains isolated from final effluent of Hospital 2 showed highest resistance to Amikacin and Colistin which is 100% and 86% and 82% resistance to Gentamycin and Ciprofloxacin. The gene primers used for the respective genes above have been amplified in the sample with a higher efficiency of 16 SrRNA, ermB and ampC primers showing a lower Cq value. Thus, these three genes were detected in the samples at high amount which showed the prominent use of the consecutive antibiotics in the clinical field

This research examined the involvement of women in various stages of fish processing in Ekiti State, Nigeria. A sampling method was used to select 90 women fish processors, and data was collected through structured interviews. The data was analyzed using descriptive statistics, such as frequencies, percentages, and means, along with charts. Additionally, probit regression analysis was conducted to identify socio-economic factors influencing women's participation in fish processing. The findings revealed that, on average, women involved in fish processing were 38.5 years old, with 57% being married and 28.4% being single. A majority (61.7%) had received formal education, and nearly all (91%) were members of cooperative societies. The study found that women were primarily engaged in scaling, gutting, and sticking (87%), with 60% using the hot smoking method. Most processing equipment was locally fabricated, with 15% using drum ovens, 25% using metal sheets, 45% using clay ovens, and 40% using kilns. The majority (85%) used firewood as a fuel source, and 89% packaged their fish in baskets and paper. The probit regression analysis indicated that age, education, access to credit, and access to markets were positively and significantly related to women's participation in fish processing. Marital status and experience in fish processing were also positively related but not significantly. The study concluded that women utilized various methods, equipment, and energy sources in fish processing. Based on the findings, recommendations were made, including assisting women in forming cooperative societies to enhance their business management skills, prioritizing women in accessing credit and loans, and stabilizing fish product prices to mitigate business risks among women processors.
