Abstract Background: Maintaining normocapnia during mechanical ventilation in anesthetized children during laparoscopic surgeries is highly recommended. There is a debate regarding the use of capnography (ETCO2) as a trend monitor for evaluation of arterial carbon dioxide levels (PaCO2). We analyzed the relationship between ETCO2 and PaCO2 with time in elective pediatric laparoscopic surgeries. Methods: This study was a prospective observational cohort analysis of 116 paired comparisons between PaCO2 and ETCO2 computed from 29 children (ASA I, 12–72 months). Arterial blood samples were withdrawn before, at 15 minutes and 30 minutes during pneumoperitoneum and 1 minute after deflation. ETCO2 value was recorded simultaneously, while arterial blood was withdrawn. PaCO2-ETCO2 relationship was evaluated by Pearson’s correlation coefficients and Bland Altman Method of agreement. Results: Out of the 116 comparisons analyzed, a PaCO2–ETCO2 difference beyond 0 to ≤ 5 mmHg was recorded in 71 comparisons (61.2%) with negative difference in 34 comparisons (29.3%). A positive significant correlation between PaCO2 and ETCO2 was recorded before (r = 0.617, p = 0.000) and at 15 minutes (r = 0.582, p = 0.001), with no significant correlation at 30 minutes (r = 0.142, p = 0.461), either after deflation (r = 0.108, p = 0.577). Bland-Altman plots showed agreement between ETCO2 and PaCO2 before inflation with mean PaCO2-ETCO2 difference 0.14±5.6mmHg (limits of 95% agreement −10.84–11.2, simple linear regression testing p-value 0.971), with no agreement at 15 minutes (0.51 ±7.15, −13.5–14.5, p = 0.000), 30 minutes. (2.62 ±7.83, -12.73–17.97, p = 0.000), or after deflation (1.81 ± 6.56, −10.93–14.55, p = 0.015). Conclusion: Usage of capnography as a trend monitor in pediatric laparoscopic surgeries may not be a reliable surrogate for PaCO2 levels. Background recommended ETCO (ETCO2 PaCO2. PaCO .

Abstract Introduction Psoriasis (PsO) is an immune-mediated chronic inflammatory disease that results in severe outcomes that impact the patient's quality of life and work productivity. We investigated the effectiveness of secukinumab in patients with chronic plaque psoriasis and psoriatic arthritis (PsA) over a 12-month period. Methods This was a longitudinal, retrospective study of the medical records of 81 patients with psoriasis and/or psoriatic arthritis who had been treated with secukinumab for at least 12 weeks. Results The Psoriasis Area Severity Index (PASI), Body Surface Area (BSA) percentage, and Dermatology Quality of Life Index (DLQI) among patients with PsO and PsO-PsA showed a statistically significant decrease from baseline over 12 months by approximately 9.86, 19.3%, and 9.7, respectively (p values < 0.001 for each). Moreover, there was a statistically significant decrease in the overall Disease Activity in Psoriatic Arthritis score (DAPSA) by approximately 22.35 from baseline over 12 months of treatment (p < 0.001). Considering the patients who started secukinumab 12 months or more prior to the study cutoff date, the 12-month retention rate was 85%. Conclusion In a Saudi real-world setting, secukinumab proved to be an efficient medication with high efficacy and retention rates.

Abstract Background: Many adjuvants are added to prolong the effects of spinal analgesia. We investigated the postoperative analgesic efficacy of the addition of midazolam or fentanyl to intrathe-cal levobupivacaine in women undergoing cesarean delivery. Methods: Eighty patients were randomly assigned to two groups (n = 40). Group M received 10 mg of 0.5% levobupivacaine plus 2 mg of midazolam. Group F received 10 mg of 0.5% levobupivacaine plus 25 μg of fentanyl. Assessments included motor and sensory block, APGAR score, time to first request for analgesia, postoperative pain score, total consumption of rescue analgesics, and adverse effects. Results: Sensory blockade was prolonged in Group M compared with Group F (215.58 ± 27.94 vs. 199.43 ± 19.77 min; p = 0.004), with no differences in other characteristics of the spinal block in intraoperative hemodynamics or APGAR score. The mean time to first request for rescue analgesia was longer in Group M (351.45 ± 11.05 min) than in Group F (268.83 ± 10.35 min; p = 0.000). The median total consumption of rescue analgesics in the first 24 hours postoperatively was 30 mg in Group M vs. 60 mg in Group F (p = 0.003). The median Visual Analog Scale (VAS) scores were lower in Group Ethan in Group F from the 8th to the 12th hour postoperatively, with no differences between the groups at other time points. The incidence of adverse effects was higher in Group F than in Group M. Conclusion: Intrathecal midazolam (2 mg) was superior to intrathecal fentanyl (25 μg) in increasing the duration of the sensory blockade and postoperative analgesia with lower postoperative pain scores and decreasing the incidence of adverse effects.

Abstract: En | Text: En | PDF: En

Rabies is endemic in Sudan with continuing outbreaks occurring annually, the most common animals affected are dogs, followed by goats and equids. This work focused on equid rabies, to elucidate the current situation of the disease through analysis of reports of equid rabies outbreaks in Sudan during 2010-2022 supported by laboratory confirmation of the disease. During the study period, 66 animals were affected during 35 equid rabies outbreaks. The highest incidences were found in Al Gezira (30.3%), followed by Darfur (24.2%) and Kordofan (15.2%). The highest incidence rate was observed during 2018 (33.3%), followed by 2015 (16.7%). Within seasons, the highest incidence rate was reported during October - December (33.3%), followed by July - September (30.3%). Chi-square analysis revealed a significant correlation between rabid animals and year, season, and state. Wald statistics demonstrated that year and season had a significant association with the disease. Virus antigen was identified (72.2%) in brain tissues using the fluorescent antibody test. Viral nucleic acid was amplified (n = 6) with a reverse transcriptase polymerase chain reaction assay. CONTRIBUTION: As equids are kept in close contact with humans and other animals in the country, according to the present investigation, equid rabies in Sudan is a potential public health concern, emphasising the importance of implementing effective control measures

RESUMO Introdução: A resposta imune a diferentes vacinas contra a doença do coronavírus 2019 (COVID-19) é pouco investigada em pacientes com doença renal em estágio terminal (DRET), especialmente no Oriente Médio e norte da África. Realizamos esta pesquisa para estimar a eficácia da imunização contra a COVID-19 em pacientes com DRET em hemodiálise regular (HD). Métodos: Nesse estudo observacional prospectivo, inscrevemos 60 pacientes com DRET em HD regular que haviam concluído o esquema de vacinação contra a COVID-19 e 30 participantes saudáveis vacinados. Os níveis séricos de imunoglobulina G da síndrome respiratória aguda grave do coronavírus 2 (SARS-COV2 IgG) foram quantificados um mês após a conclusão do esquema vacinal, e todos os participantes foram acompanhados de outubro de 2021 a março de 2022. As vacinas utilizadas no estudo eram da Pfizer-BioNTech, AstraZeneca e Sinopharm. Resultados: O nível mediano de SARS-COV2 IgG foi menor em pacientes em HD do que em participantes saudáveis (p < 0,001). Com relação ao tipo de vacinação contra a COVID-19, não houve diferença estatística nos níveis de SARS-COV2 IgG entre pacientes em HD. Durante o período de observação, nenhum dos pacientes em HD teve COVID-19. Conclusão: A vacinação contra a COVID-19 pareceu ser eficaz na proteção de pacientes em HD por 6 meses e os efeitos colaterais das vacinas foram toleráveis.

ABSTRACT Introduction: The immune response to different Coronavirus Disease 2019 (COVID-19) vaccines is under-investigated in end-stage kidney disease (ESKD) patients, especially in the Middle East and North Africa. We carried out this research to estimate the effectiveness of COVID-19 immunization in ESKD patients on regular hemodialysis (HD). Methods: In this prospective observational study, we enrolled 60 ESKD patients on regular HD who had completed COVID-19 vaccination and 30 vaccinated healthy participants. Serum levels of severe acute respiratory syndrome coronavirus 2 immunoglobulin G (SARS-COV2 IgG) were quantified 1 month after completing the vaccination schedule, and all participants were followed up from October 2021 to March 2022. The vaccines used in the study were from Pfizer-BioNTech, AstraZeneca, and Sinopharm. Results: The median level of SARS-COV2 IgG was lower in HD patients than in healthy participants (p < 0.001). Regarding the type of COVID-19 vaccination, there was no statistical difference in SARS-COV2 IgG levels among HD patients. During the observation period, none of the HD patients had COVID-19. Conclusion: COVID-19 vaccination appeared to be protective in HD patients for 6 months and the side effects of vaccines were tolerable.

ABSTRACT Soil salinization is more aggravating than ever before and techniques are needed to mitigate this problem; understanding salinity-fertilizer relationship is of considerable economic importance for promoting crop growth and productivity in saline soil. A pot experiment was done in a greenhouse to determine whether the N could alleviate the negative effect of different salts compositions on the growth, and physiological attributes of the two most used Sudan sorghum (Sorghum bicolor (L.) Moench) cultivars (Wadahmed and Tabat). The plant was subjected to the salt stress at 0, 0.3419 M NaCl, and 0.1408 M Na2SO4, and four levels of N application 0, 4, 8, and 12 g N kg-1 soil, designated as N0, N1, N2, and N3, respectively. Results showed that Na2SO4 was reduced plant height, leaf area index, number of leaves, dry weight (DW), chlorophyll a, total chlorophyll content, and increased soluble protein content, activities of peroxidase (POD) and catalase (CAT) activities by 16.4%, 29.7%, 61.5%, 28.7%, 39.6%, 12.7%, 99.7%, 34.3%, 51.8%, respectively, when compared with the non-saline treatment. The Na2SO4 salt had a more harmful effect than NaCl. This study revealed that N fertilizer was successful for alleviating the adverse impacts of both types of salt. In this study, 12 g N kg-1 soil was most effective on most of the measured parameters of two sorghum cultivars. These findings demonstrated that the N soil amendment application could alleviate the harmful impact of salinity. ‘Wadahmed’ was more tolerant to salinity stress than ‘Tabat’ during the boot stage of sorghum plant.

Abstract: En | Text: En | PDF: En

The objective of this study was to develop two simple and selective visible spectrophotometric methods for the determination of antihistamine drug triprolidine hydrochloride (TRH) in the capsules. The methods were based on the formation of ion-pair complexes between TRH and two dyes, namely, bromocresol green (BCG) and bromophenol blue (BPB). The produced ion-pair complexes were measured at 415 and 410 nm for BCG and BPB methods, respectively. Beer’s law was applicable in the concentration ranges of 2.50-15.0 μg mL-1 TRH for both methods. The molar absorptivity values were found to be 2.12 × 104 and 2.07 × 104 L mol-1 cm-1 for the BCG method and BPB method, respectively, and the Sandell’s sensitivity values were 0.0149 and 0.0152 μg cm-2. The limits of detection and quantification were calculated and found to be 0.29 and 0.86 μg mL-1 for the BCG method and 0.31 and 0.95 μg mL-1 for the BPB method.

ABSTRACT Objective: To determine caries prevalence and its association with body mass index in school children between 9-12 years of age in Hail, Saudi Arabia. Material and Methods: This descriptive cross-sectional study included 524 school children 9-12 years of age. These children were selected from 9 Public schools in Hail Province. Dental caries was recorded as per criteria established by the World Health Organization using assessment form for children 2013. Children were weighed using an electronic scale nearest to 0.1 kg with children attired in light clothing and wearing no shoes. The height was measured using a stadiometer to the nearest full centimeter with the children in a standing position. Body Mass Index (BMI) was determined using the formula BMI = kg/m2. Results: Caries prevalence in the population was 86%. The comparisons of mean DMFT between the groups demonstrate higher scores in the overweight group (mean=2.43) compared to normal weight (mean=1.85) and underweight children (mean=1.56) which is statistically significant (p=0.000). Bonferroni Post hoc test to compare the underweight and overweight group (p=0.000) and overweight and normal weight (p=0.000) were highly significant. Conclusion: A positive correlation of caries severity, namely DMFT, with BMI is established.

To this end, varying contact loads and sliding speeds were applied to tribological tests. The ZA-27 alloy was produced using gravity die casting (GDC) and new rheo-casting (NRC) methods. The results showed that the microstructure of GDC ZA-27 alloy is dendritic containing α and η phases. While the NRC alloy microstructure demonstrates a semi-globular structure of fine equiaxed α phase bordered by eutectoid α and η. The NRC alloy achieved an improvement in tensile, hardness, and elongation properties by almost 15%, 20%, and 25%, respectively. Regarding tribological properties, the NRC alloy achieved an enhancement in tribo-behavior by lowering the coefficient of friction (COF) to about 67% than the GDC alloy. Further, the results showed that the wear rate recorded an increment with applied load for both GDC and NRC alloys. Though, the results showed that the wear rate with NRC alloy was lower compared to the GDC alloy with about 84% at 160N normal load. The worn surfaces of NRC alloys were characterized by smooth and shallow wear grooves. While the GDC alloy worn surfaces were rougher and experience deeper grooves and damage.

SUMMARY OBJECTIVE: The World Health Organization defines infertility as the inability to get pregnant after 12 months of unprotected sexual activity. This study was conducted to estimate the levels of gene expression for two mature miRNAs (i.e., miR-122 and miR-34c-5p) to evaluate susceptibility to male infertility. METHODS: This study included 50 male patients with idiopathic infertility who were admitted to hospital from the period November 2021 to May 2022 and another group consisting of 50 apparently healthy individuals used as controls. RESULTS: miR-122 level was significantly highest in azoospermia and followed by oligospermia, 39.22 (31.88) versus 37.34 (20.45), respectively. In addition, there was a very significant difference in miR-34c-5p levels between the study groups (p<0.05). CONCLUSION: Two miRNAs, namely, miR-34c-5p and miR-122, can be used as predictive and diagnostic biomarkers for infertility.

Abstract Due to the extensive usage in the industry, the structural integrity of hollow cylinders is seen as a critical goal for stakeholders. Fracture is the most common failure mode for cylinders, which occurs due to crack propagation. Cracks can be found in single or multiple forms; when numerous, crack interaction occurs, which can exacerbate pressures beyond the material's resistance. This work uses Ansys software to examine double parallel interacting surface cracks on a hollow cylinder. The stress intensity factor (SIF) was used to describe the driving force that was used to characterize crack interaction for various crack geometries. To conduct extensive research, this study evaluated a wide range of crack aspect ratios as well as the relative depth of the crack. The findings of this study indicated that the shielding effect demonstrated parallel crack interaction. In addition, an empirical mathematical approach for predicting SIFs for double parallel cracks via single crack SIFs has been developed. The validation of the proposed model using performance evaluation metrics revealed an acceptable rate of error of less than 5%. industry stakeholders propagation forms numerous materials material s resistance cylinder SIF (SIF geometries research addition developed 5 5%

Abstract The traditional method of fixing cracked pipes by welding needs stopping the production. In this study, a composite material is used to repair pipelines without interrupting production, saving both time and money. Hand Layup and vacuum infusion techniques were used to prepare glass strand mat and intra-ply hybrid glass - carbon fibers composites repairs. To show the composites' strength, blister, double cantilever beam, and peel tests were conducted. A novel modified blister test was utilized to show effectiveness of laboratory tests on real pipeline. The results indicate that vacuum infused intra-ply hybrid composite exhibited the highest strength. The experimental results of the best composite were compared with the finite element model under blister test, and the results were found to be identical. The modified blister test on the real pipe provides a better indication about the good strength of the composite repair compared to previous researches. production study money intraply intra ply repairs beam conducted pipeline identical researches

Abstract: En | Text: En | PDF: En

The debate around viable global governance has become increasingly topical, particularly from the perspective of countries in the Global South. Concerning Africa, despite the continent's quest to reform the United Nations Security Council (UNSC), existing research has failed to comprehensively address the topic. Consequently, this article explores the arguments and challenges surrounding Africa's drive to secure a permanent voice in the UNSC. It argues that despite the enduring legacies of colonialism, neocolonial interventions, and being the primary concern of the UNSC agenda, Africa's claim for fair representation in the Council remains. The article attempts to address the research gap and contribute to the existing debate by examining why Africa has failed to be represented in the UNSC. Africa's collective initiative towards reforming the UN system is instrumental in ensuring inclusive and sustainable global governance. Nonetheless, Africa's insistence on immediate and full veto power for new entrants and its demand for representation merely through numbers inside the UN are unfeasible.

Abstract: En | Text: En | PDF: En

Justice has a high status in Islamic societies, and as one of the most important human ideals, has long been the focus of thinkers and researchers. In fact, when the citizens do not understand the presence of justice in the behaviour of the officials of their society, their trust in the current procedures, and consequently the public participation will be affected. Considering the importance of the subject, the present study has been conducted with the aim of investigating the effect of perception of justice on citizens' trust and participation in the creation of a democratic Islamic society. The statistical population of this research included 3578 Indonesian Muslim citizens in 2022, and the research questionnaires were distributed among them. Data analyses were done using Statistical Package for the Social Sciences (SPSS) and Linear Structural Relations (LISREL) statistical software. The results of statistical analyses indicated that the perception of Islamic justice does not have a significant effect on the participation of Muslims in creating a democratic Islamic society. In addition, the perception of Islamic justice has a positive effect on the trust in officials of the Islamic society. Moreover, trust in the officials of the Islamic society positively affects the citizens' participation in creating a democratic Islamic society. CONTRIBUTION: According to the results of this research, it is necessary for the officials of the Islamic society to use all their efforts in creating a justice-oriented Islamic society in order to create trust among the citizens, and to involve Muslims in development decisions and to establish democratic Islamic society
