No full textDetermination of end point of fluid resuscitation using simplified lung ultrasound protocol in patients with septic shock
No full textContext Fluid administration requires dynamic measures that are preferred over static ones as they are easy to apply and noninvasive. Thoracic ultrasound could be used in assessing extravascular lung water by visualizing the so-called B-lines.
Aim To assess the role of a new simple ultrasound protocol in identifying the end point of fluid resuscitation in patients with septic shock.
Settings and design A single-blinded randomized controlled trial was carried out on 80 consecutive adult patients with septic shock.
Patients and methods Patients were divided into two groups: the first received fluid resuscitation according to early goal-directed therapy with a target central venous pressure of 8–12 mmHg, whereas the second received fluids guided by simplified lung ultrasound protocol till reaching a score of 16.
Statistical analysis used IBM SPSS software package, version 20.0 was used for statistical analyses.
Results The ultrasound score showed a negative significant weak correlation with the hypoxic index (Spearman’s r=−0.39, P=0.012), whereas it showed a positive moderate significant correlation with the central venous pressure readings (Spearman’s r=0.50, P=0.001), and positive moderate significant correlation with the congestion by chest radiography (Spearman’s r=0.47, P=0.002). A score of more than or equal to 10 in patients with septic shock with a sensitivity of 84.21% and specificity of 90.48% was concluded, upon which resuscitation should be terminated (area under the curve was 0.818 with a significant correlation of P=0.001).
Conclusion Simplified lung ultrasound protocol could be used as an end point of fluid resuscitation in patients with septic shock to avoid fluid overload effects
The Environmental I mpacts of the New Arbaat dam on arbaat Area of the Red sea
No full textThe objective of this study in the Red Sea State was to assess the
environmental impacts of Khor Arbaat new dam (RSS) constructed to
supplement drinking water in city of Port Sudan and the rural areas.
The four areas of Arbaat dam used in this study composed Arbaat
west Dam, Arbaat east Dam, Arbaat Almoya and Arbaat Alziraa.
The sample of the study was selected randomly consisting of 52
respondents, representing about 3% of the total population of Arbaat area.
Results indicated that the construction of the Dam led to a decrease
in the flow of water in the Khor used for irrigation of agricultural land,
pasture, and for drinking. Consequently agricultural production and
carrying capacity of pasture decreased downstream. Furthermore the
income of the families in the area also dropped.
Negatively affected farmers started looking for marginal jobs in
Port Sudan city compensate for their income loss. They practiced cutting
of trees, working in Port Sudan water Station, Port and Dam.
These new events led to unsuitability in income and settlement.
Construction of the Dam increased ground water level in the area
of Arbaat east Dam giving a good chance for irrigating larger areas and
increase production of crop.
It could be concluded that, In order to improve settlement:
• Encourage new employment opportunities.
• Relocate of new residential area for affected people.
• Improvement of agricultural system ,provision of basic services
health ,education and environmental sanitatio

No full textTo study the effect of supplementation of moringa seed cake on the ovarian dynamics and hemodynamics, hormonal and antioxidant capacity of yearling ewes, native ewes (n=20) were equally divided into control supplemented the basal diet and moringa seed cake (MSC) supplemented orally 7.0g daily for 45 days. After 17 days of starting supplementation, exogenous 45mg progesterone sponges were inserted for a short period (6 days) and each animal was administrated 2.5mg Dinoprost tromethamine on the day of sponge removal. Ultrasound Doppler was conducted and blood samples were collected on the day of sponge insertion (Day -6), sponge removal (Day 0), Days 2, 9, 15, and 21. Results indicated increased dominant follicle diameter and number in ewe-lambs supplemented with MSC on Day 2 (P=0.0007), 9 (P=0.009), and Day 21 (P=0.005)Subordinate follicle diameter of MSC increased on Day -6, 2 (P<0.0001), 9 (P=0.004) and 21 (P=0.012). The follicle’s average circumference, area, and perimeter increased (P<0.0001) in ewe-lambs supplemented with MSC on Days 2, 9, and 21. CL diameter, perimeter, and area of MSC reached the highest (P<0.0001) on Day 15 but those of control reached the maximum diameter (P=0.032) on Day 21. Ovarian color area of MSC increased (P<0.01) on days 0 and 2. The concentrations of total antioxidants, glutathione reduced, catalase, and SOD increased in ewe lambs supplemented MSc. In conclusion, MSC improved follicle and luteal development, ovarian hemodynamics, and response to synchronization using short-term exogenous progesterone. MSC improved the antioxidant capacity and decreased lipid peroxidation during the estrus of ewes

No full textExploring the Drivers of Green SMEs:A Multidimensional Qualitative Study
No full textDespite growing global attention to sustainable entrepreneurship, limited understanding persists regarding how financial, institutional, and leadership dynamics jointly shape the green transition of small and medium-sized enterprises (SMEs). Responding to this gap, the present study offers a novel, ecosystem-based perspective that examines how multiple drivers and barriers co-evolve to influence SME sustainability transitions. Drawing from institutional theory and the resource-based view, and using the United Arab Emirates as a representative context, the paper presents qualitative evidence from 96 stakeholders—including government officials, SME leaders, academics, consultants, and finance professionals. Findings include evidence of the complex interplay between internal capabilities and external institutional structures that determine the pace and depth of green transformation. The findings reveal that financial challenges—particularly high borrowing costs, investor risk aversion, and the absence of specialized green finance instruments—constitute the most significant barriers to sustainability adoption. Conversely, government support mechanisms, technological advancement, and leadership commitment act as powerful enablers, promoting innovation and resilience. The study further demonstrates that SMEs’ ability to signal environmental and social value to investors depends on coherent policy frameworks and integrated public–private financing mechanisms. By integrating insights informed by theory and empirical data, this research proposes a multidimensional framework linking green finance accessibility, institutional readiness, and organizational capability development, advancing theoretical understanding of SME sustainability transitions. The findings provide actionable guidance for policymakers, financial institutions, and ecosystem stakeholders seeking to strengthen national green SME ecosystems and offer comparative insights for other economies pursuing sustainable and inclusive growth
