Published: February 2024

Background: Evidence indicating the effect of vitamin D supplementation on improving the clinical outcomes of COVID-19 is limited. Objectives: This study aimed to examine the effect of high-dose vitamin D on mortality and hospital length of stay in ICU patients with COVID-19. Methods: A single-center, double-blind, placebo-controlled, randomized clinical trial study was conducted on 61 patients with moderate to severe COVID-19 hospitalized in the ICU of Golestan Hospital, Kermanshah, Iran. Participants were randomly divided to receive a single dose of 300 000 IU vitamin D3 intramuscularly (n = 31) or placebo (n = 30). The primary outcomes were the length of hospital stay and in-hospital mortality. Secondary outcomes were the length of stay in the ICU, the number of patients requiring mechanical ventilation, and the serum level of 25-hydroxyvitamin D. Results: Out of 61 randomized patients, 44 patients with a mean age of 53.49 ± 13.2 years, body mass index of 29.80 ± 5.0 kg/m2, and serum vitamin D level of 24.36 ± 4.47 mg/dL were included in the study for primary analysis, of whom 31 (70.5%) cases were men. Median (interquartile range), the length of hospital stay between the vitamin D group (5.0 [6.0 - 11.0] days), placebo group (11.0 [6.0 - 17.0] days) (log-rank P = 0.23; unadjusted hazard ratio [HR] for hospital discharge, 3.4 [95% confidence interval [CI], 0.4 - 28.05]; P = 0.25; adjusted HR, 0.04 [95%CI, 11.52 - 0.0001]; P = 0.27) and mortality (unadjusted odds ratio [OR], 0.63 [95% CI,0.09 - 4.21]; P = 0.63; adjusted OR, 0.46 [95%CI, 0.03 - 6.55]; P = 0.57) showed no significant difference between the two groups before and after the adjustment of confounding factors. No significant difference was observed between the two groups regarding the need for mechanical ventilation (unadjusted OR for intubation = 2.1 [95% CI, 0.17 - 25.01]; P = 0.55), adjusted OR = 1.16 [95%CI, 0.04 - 27.57]; P = 0.92), and the length of stay in ICUs (log-rank = 2.49, P = 0.114; unadjusted HR for ICU discharge, 6.28 [95%CI, 0.5 - 78.42]; P = 0.15; adjusted HR = 21.48 [95%CI, 0.12 - 3677.48]; P = 0.24). Conclusions: Based on the results, A high dose of vitamin D did not significantly reduce mortality and hospital length of stay in ICU patients with COVID-19.

Authors:   Department of Business Administration, Leading University, Sylhet, Bangladesh., Khanom Musammat Tahmina
Published: February 2024

Equity crowdfunding is an emerging form of entrepreneurial finance that has gained significant attention in recent years. It enables startups and small businesses to collect funds from many investors through online platforms. While equity crowdfunding has the potential to overcome traditional funding barriers and democratize access to capital, there is a lack of consensus on its effectiveness and impact on startups and the wider entrepreneurial ecosystem. This paper provides an overview of leveraging equity crowdfunding for entrepreneurial financial support. It discusses the concept of equity crowdfunding, its evolution, and the benefits and drawbacks of this form of financing along with some comparative analysis. It also reviews the existing literature on equity crowdfunding and highlights its practical implications, limitations, and policy implications. Furthermore, the paper discusses the regulatory environment of equity crowdfunding and its impact on entrepreneurs and investors. The research concludes with recommendations for entrepreneurs considering equity crowdfunding as a source of financing. The study's results highlight the pivotal influence of regulatory frameworks on equity crowdfunding outcomes, suggesting that a favorable regulatory environment correlates with increased success rates, creating a supportive ecosystem for entrepreneurs and investors. Policy makers can contribute significantly to providing regulatory clarity to ensure that entrepreneurs have access to equity crowdfunding for a financing option.
Development of the stoic teachings in antiquity
Authors: Limaj Elona
Published: February 2024

Modern stoicism is becoming increasingly popular in the world: a large number of non-fiction books are published on this topic; many videos reveal the essence of this philosophy; podcasts, articles in magazines, etc. are also dedicated to stoicism. Thus, there is a need to study Stoicism at the scientific level. The study aims to provide an in-depth examination of the history of the Stoic doctrine, in the course of which it is necessary to determine the ideological origins of the Stoic doctrine and the contribution of the Stoics to the development of philosophy. One of the study objectives is to compare the philosophy of Stoicism with other schools of thought to fully reveal the purpose of the article. Analysis, analogy, systematisation, the philosophical pluralism method, synthesis, generalisation, and comparison were used in the study. The development of the Stoic doctrine in comparison with other philosophical concepts of the ancient times was studied. As a result of the analysis of philosophical texts, it was found that Stoicism arose from Kinism and developed on a par with this doctrine. Stoic philosophers had an important influence on philosophy by creating a system of dividing the world into three parts. The Stoics are the continuators of Socrates’ philosophy, and the pedagogical ideas of Stoicism are similar to the general ideas of that time. Stoicism is closely related to Epicureanism, and the Stoics also developed their method of self-analysis. The general trends in the development of this philosophy preserve ancient traditions. Stoicism, as a philosophical trend, developed over a long period and managed to preserve its basic principles unchanged. The study has created several scientific hypotheses that can be considered further at the scientific level, in particular, the following topics: the relationship between Stoicism and Epicureanism; pedagogical ideas of the Stoics; the Stoic method of introspection require further in-depth research by scholars. Such hypotheses can be useful for various groups of people interested in the philosophy of Stoicism and its application in the modern world and life, such as academics (philosophers, researchers), psychologists, managers, and ordinary people seeking personal development and a better understanding of themselves

The aspect of human life, making nanotechnology an exciting field for biomedical applications. Over the years, metal nanoparticles, such as silver, have attracted a lot of attention because of their extraordinary optical, electrical, and antibacterial qualities. Unfortunately, those nanoparticles' aggregation and toxicity have restricted their employment in more advantageous applications. Choosing therapeutically active bimolecular judiciously to functionalize the surface of these particles would undoubtedly improve their biological applicability and biocompatibility. In addition to providing an overview of the current approaches being used to biofunctionalize silver nanoparticles for certain purposes, the current review the distinct size-dependent properties of nanoscale materials have had a significant impact on every aims to highlight the application areas of these particles. Nanotechnology is a promising subject for biomedical applications because of the distinctive size-dependent features of materials at the nanoscale that have greatly touched all aspects of human life. Because of their exceptional optical, electrical, and antibacterial qualities, metal nanoparticles—like silver—have attracted a lot of attention over time. However, their employment in highly optimized applications has been limited due to their poisonous nature and tendency to aggregate. The biocompatibility and biological applicability of these particles are certain to be improved by the logical selection of therapeutically active bimolecular to functionalize their surface. The present review endeavors to emphasize the various application areas of silver nanoparticles while providing an overview of the current approaches entailed in biofunctionalizing these particles for particular uses.

Role of endoscopic duodenojejunal bypass liner in obesity management and glycemic control
Authors: Igi Willian Ferreira , de Oliveira Victor Lira , Matar Ayah , de Moura Diogo Turiani Hourneaux
Published: February 2024

The treatment of obesity and its comorbidities ranges from clinical management involving lifestyle changes and medications to bariat­ric and metabolic surgery. Various endoscopic bariatric and metabolic therapies recently emerged to address an important therapeutic gap by offering a less invasive alternative to surgery that is more effective than conservative therapies. This article compre­hensively reviews the technical aspects, mechanism of action, outcomes, and future perspectives of one of the most promising endoscopic bariatric and metabolic therapies, named duodenojejunal bypass liner. The duodenojejunal bypass liner mimics the mechanism of Roux-en-Y gastric bypass by preventing food contact with the duodenum and proximal jejunum, thereby initiating a series of hormonal changes that lead to delayed gastric emptying and malabsorptive effects. These physiological changes result in significant weight loss and improved metabolic control, leading to better glycemic levels, preventing dyslipidemia and non-alcoholic fatty liver disease, and mitigating cardiovascular risk. However, concern ex­ists regarding the safety profile of this device due to the reported high rates of severe adverse events, particularly liver abscesses. Ongo­ing technical changes aiming to reduce adverse events are being evaluated in clinical trials and may provide more reliable data to sup­port its routine use in clinical practice.
Massive postvaginoplasty retrovaginal hematoma: A case report
Authors: SULE KRISTINA , WERE FRANCIS
Published: February 2024

Case presentation: A para 4+0 with a history repeated of macrosomic fetuses and four subsequent spontaneous vaginal deliveries highlighted by third- and fourth-degree perineal tears presented with vaginal laxity requiring surgical vaginoplasty. Postoperatively, she developed acute urinary retention, weakness, lethargy, and pallor and was noted to have a massive posterior vaginal wall hematoma, which was soon evacuated, and vaginoplasty was successfully revised.
Discussion: Urinary retention is a unique symptom of retrovaginal hematoma, but it must be considered following vaginoplasty. During vaginoplasty, the posterior vaginal wall expands to abut the anterior vaginal wall and inferior urethral wall, preventing evacuation of the bladder. The posterior vaginal wall is elastic and able to discretely accommodate a large amount of blood loss with no signs of vaginal bleeding and should be a point of examination following vaginoplasty.
Conclusion: The expected signs and symptoms of vaginoplasty complications are vaginal bleeding and perineal tenderness. Urinary retention, pallor, and other signs can indicate a retrovaginal hematoma. Cosmetic gynecology practitioners should consider the elasticity and discreetness of the posterior vaginal wall and its ability to accommodate massive hematomas with few signs.

Background: Mesenteric ischemia is a rare condition with a high mortality rate of 24-94%. Acutely, it occurs because of sudden vascular emboli or thrombi and presents with severe abdominal pain disproportionate to physical examination findings with other nonspecific symptoms.
Case presentation: A para 2+0 gravida 3 presented at 36 weeks 4 days of gestation with a 1-day history of worsening lower abdominal pain radiating to the back and reduced fetal movements. Mild pallor was observed, and vaginal examination showed a latent phase of labor. Shortly after admission, the patient developed diaphoresis and mild confusion with worsening pain, and an urgent ultrasound confirmed intrauterine fetal demise. Subsequently, she developed dizziness and progressed to loss of consciousness, with resuscitation promptly begun but unsuccessful. A diagnosis of extensive mesenteric ischemia was made postmortem.
Discussion: Bowel ischemia can result from occlusions of major abdominal vessels and progress to necrosis, gangrene, and eventually perforation with subsequent severe complications. Uterine vasoconstriction in pregnancy itself contributes to a hypercoagulable state, increasing the risk of mesenteric ischemia, with a 10-fold higher risk in those conceiving by in vitro fertilization and embryo transfer. Other venoocclusive causes include atrial fibrillation, coagulopathic, malignancy, and radiation. Diagnosis is mainly by computed tomography. Confirmation is made by emergency laparotomy and histology. Blood investigations like lactate levels may be elevated in sepsis and screening for coagulopathies after diagnosis is made is indicated. Management involves anticoagulants, thrombolysis, and surgical interventions, such as resection and anastomosis, or endarterectomy, and anterograde bypasses. Masked symptoms, rapid progression, and severe resource limitations made this a difficult case to diagnose and manage.
Conclusion: Given the rarity of the incidence of mesenteric ischemia, a very high level of suspicion is required to diagnose and promptly manage this emergency.
Advancing Accountability

In Alkhatib and Others v. Greece, the European Court of Human Rights (ECtHR) has condemned Greece for yet another instance of human rights violations in border management. By underlining the importance of clear regulations and adequate evidence within border operations, the Court showed avenues to enhance the accountability framework for violations perpetrated at Europe’s borders. Its decision contrasts favourably with the approach taken in the EU at large, where both legislators and national and supranational courts generally disregard the opacity in regulations governing border operations and the difficulty of collecting evidence for migrants.

Introdução: A pandemia de Covid-19, causada pelo novo coronavírus de provável origem na China apresentou uma grande influência na condução e desfecho no tratamento das afecções neurocirúrgicas. Objetivo: O objetivo deste trabalho é avaliar o efeito dessa infecção na mortalidade durante a hospitalização em pacientes neurocirúrgicos. Métodos: Foram estudados 93 pacientes internados para tratar doenças neurocirúrgicas entre 21/03/2020 e 30/06/2020. A média das idades foi de 63,71 (15 a 94 anos). Cinquenta e três pacientes eram do sexo masculino e 40 do feminino. Nove pacientes foram diagnosticados com COVID durante a internação. Da amostra total, 67 pacientes foram submetidos a procedimento neurocirúrgico (9 COVID+ e 58 COVID-).Resultados: Entre os pacientes operados, a probabilidade de óbito nos pacientes portadores de Covid-19 foi cinco vezes maior que aos negativos para a doença. Uma análise de regressão logística multivariável verificou que a idade e a presença de Covid-19 foram fatores preditores independentes de mortalidade. A cirurgia não foi um fator significativamente associado à mortalidade. Conclusão: A Covid-19 aumentou em cinco vezes a probabilidade de óbitos em pacientes operados.

O presente trabalho buscou analisar o crime de infanticídio, caracterizado quando a mãe mata o próprio filho sob a influência do estado puerperal, tipificado no Artigo 123 do Código Penal. Os referenciais analíticos estão baseados nas normas jurídicas vigentes no país, nos protocolos de prática médico-legal e também na produção de conhecimento formulada pela antropologia. Entre os principais resultados, destaca-se que o crime de infanticídio é de difícil caracterização, em virtude de sua correlação a condições socioeconômicas e houve uma constatação sobre a insuficiente disponibilidade de dados nacionais sobre o infanticídio no Brasil.

This research aimed to assess the quantity and quality of raw Murrah buffalo milk in a mixed crop-livestock farming system in North Sumatra, Indonesia. The study was conducted at the Sumber Ternak Abadi livestock farm in Pagar Merbau District, North Sumatra, Indonesia, established in 2012 within an oil palm plantation. The study observed 40 lactating Murrah buffaloes. Variables included milk production and quality metrics such as total plate count in colony-forming units per ml, water content percentage, total solids, fat content, and pH. Results demonstrated a milk yield standardized to 305 days ranging from 1,200.78±490.25 to 1,505.71±589.73 kg/head/lactation. The total plate count was 2.1 x 105 ± 0.32 CFU/ml, total solids were 16.87% (w/w), fat was 5.7% (v/v), and pH was 6.73. The results confirmed that the raw Murrah buffalo milk from the observed farm meets the Indonesian National Standard for milk quality. A significant positive correlation was found between water content and total bacterial colony count (r = 0.82, p < 0.01), suggesting that higher water content in milk correlates with increased bacterial colonies.

It is of interest to assess the antioxidant and anti-inflammatory properties of Terminalia chebula gold nanoparticles. Anti-inflammatory and antioxidant properties of the nano composite were assessed using Bovine Serum Albumin (BSA) and DPPH Assay respectively at 10 µL, 20 µL, 30 µL, 40µL, 50 µL. Values for anti-inflammatory property of nanoparticles were higher than the standard values at 40µL, 50 µL concentrations. Percentage of inhibition was highest at 40 µL (86%) and 50 µL (84.6%). The values for antioxidant property of nanoparticles were found to be higher than the standard values at concentrations except at 40µL, 50 µL. Percentage of inhibition was highest at 20 µL (86.2%).Within the limits of the study it can be concluded that Terminalia chebula mediated gold nanoparticles have exceptional anti-inflammatory and antioxidant properties and further can be incorporated in dental material or can be used to coat suture materials to improve their properties.

Looted objects, Badeng histories and Brooke peacemaking
Authors: Mashman Valerie
Published: February 2024

This paper explores the meaning of objects that were looted from the Badeng and were subsequently donated by a Brooke administrator to the Sarawak Museum, as a trigger to examining Badeng responses to Brooke rule. The official histories of Sarawak express the satisfaction of the Brooke officers with their efforts at state-making through punitive expeditions, but these are underpinned by local oral histories of arson, violence and devastation. Through intermediaries, the Badeng succumbed to Brooke rule and are portrayed as being happy with the efforts of peace-making, yet they eventually migrated away from the Brooke domain. As such, these looted objects provide an opportunity to include Badeng historical narratives which convey agency, cunning, resistance and independence in the face of Brooke rule. At the same time, the reconstruction of the history of the Badeng through oral narratives makes a potentially rich contribution towards the popular history of the nation. This leads to the wider issue of the need for a methodology to retell these histories without reopening old grievances and enmities in order that history can be told and understood within a plural society.

The spread of Islam in Taiwan is inseparable from the history of Islam's entry into Tiongkok, which began with the migration of Chinese Muslims to Taiwan in the 17th century and was followed by subsequent migrations. This research analyses the phases and influences brought by Muslim migrants to Taiwan. The method used in this research is the historical research method, including heuristics, source criticism, interpretation and historiography. The results of this study show that there are four phases of Muslim migration to Taiwan: the first phase occurred in the 17th century, the second phase 1952-1961 which occurred in two waves, the first wave 1952-1954, the third phase occurred in 1961, this phase is also known as the evacuation phase of KMT Veterans from Burma and Thailand. The fourth phase occurred in 1989, with the influx of migrant workers from Tiongkok, Burma, Thailand, Indonesia and Malaysia; these immigrants positively impacted the development of Islam in Taiwan. Evidence of the development of Islam in this fourth phase is the existence of halal certification, halal restaurants and hotels, Muslim-friendly neighborhoods, the establishment of the Indonesian Mosque (Masjid At-Taqwa), the emergence of Muslim communities (FORMMIT, Chinese Muslim Association, Indonesian Student Association) and the presence of Indonesian Muslim organizations (Nahdlatul Ulama and Muhammadiyah).
