This paper examines challenges faced by novice school principals in Somalia using quantitative research. The International Study of Principal Preparation (ISPP) survey was employed with a sample of 181 principals serving for a maximum of three years. Data were collected from primary and secondary schools in Mogadishu and the Puntland region. Statistical analyses, including frequency, t-test, ANOVA, and Kruskal Wallis, were performed using SPSS. Findings reveal no significant differences in problematic aspects based on gender, age, experience, or student enrollment. However, education background, school location, and school level showed significant differences in problematic aspects.

The academic performance of students has been a subject of interest for educational researchers for a while; however, most of the research in this area was done outside of Somaliland. Therefore, this study examined factors affecting the academic performance of students in Burao, Somaliland. The study aimed to investigate the influence of employment status, learning style preference, test anxiety, and English communication problems on the students' GPAs. The undergraduate students of the University of Burao participated in this study. Using stratified sampling, 333 students were chosen from six different faculties, and data was gathered by a questionnaire. The response rate was 69%, so data from 230 students were analyzed using a Binomial logistic regression with the help of SPSS 21. The result indicated that employment status has no significant effect on students' GPAs, while the other three variables had effects on it. Regarding the influence of learning style preference, the students with auditory learning styles had 3.0 times higher odds of achieving higher grades than students with visual learning styles. The study also discovered that for every one-unit increase in test anxiety, students were 0.56 times less likely to achieve higher grades. Moreover, for every one-unit increase in English communication problems, students were 0.63 times less likely to achieve higher grades. In short, of the four predictor variables, only learning style preference, test anxiety, and English communication problems affected students' GPAs in different ways. Therefore, the study made several recommendations including the use of various lecture delivery techniques by lecturers and the development of an English communication policy by the university.

Salinity is one of the substantial threats to plant productivity and could be escorted by other stresses such as heat and drought. It impairs critical biological processes, such as photosynthesis, energy, and water/nutrient acquisition, ultimately leading to cell death when stress intensity becomes uncured. Therefore, plants deploy several proper processes to overcome such hostile circumstances. Grapevine is one of the most important crops worldwide that is relatively salt-tolerant and preferentially cultivated in hot and semi-arid areas. One of the most applicable strategies for sustainable viticulture is using salt-tolerant rootstock such as Ruggeri (RUG). The rootstock showed efficient capacity of photosynthesis, ROS detoxification, and carbohydrate accumulation under salinity. The current study utilized the transcriptome profiling approach to identify the molecular events of RUG throughout a regime of salt stress followed by a recovery procedure. The data showed progressive changes in the transcriptome profiling throughout salinity, underpinning the involvement of a large number of genes in transcriptional reprogramming during stress. Our results established a considerable enrichment of the biological process GO-terms related to salinity adaptation, such as signaling, hormones, photosynthesis, carbohydrates, and ROS homeostasis. Among the battery of molecular/cellular responses launched upon salinity, ROS homeostasis plays the central role of salt adaptation.

Abstract Background Quality sleep is vital for well-being, especially for healthcare workers facing high risks of fatigue and burnout. Sleep deprivation impairs cognitive and motor functions, contributing to medical errors. Addressing sleep disorders among healthcare professionals is crucial for enhancing patient care. Tailored interventions are needed to support their well-being and improve healthcare outcomes. Objective To evaluate the effect of Sleep Quality and its Deprivation on Sudanese Healthcare Professionals amidst conflict in Sudan. Methods A cross-sectional online survey of Sudanese doctors was conducted using convenience sampling. The questionnaire covered sleep quality, daytime sleepiness, and psychological well-being. Pilot testing ensured questionnaire clarity. Data collection utilized Google Forms distributed through social media and professional networks. A minimum sample size of 384 was calculated. Statistical analysis included descriptive statistics and various tests for significance. Data were securely stored and analyzed using SPSS and R software. Results Among 649 participants, 404 (62.2%) were women, with a mean age of 30.34 years. Most were single (434, 66.9%). General practitioners constituted the largest professional group (267, 41.1%), followed by registrars/residents (142, 21.9%). Participants took an average of 43.70 minutes to fall asleep and slept an average of 5.90 hours per night. According to the PSQI, 300 (46.2%) reported mild sleep disturbance, 287 (44.2%) moderate, 42 (6.5%) severe, and only 20 (3.1%) normal sleep. The ESS revealed 285 (43.9%) with lower normal daytime sleepiness, 188 (29.0%) with higher normal, and various levels of excessive daytime sleepiness. Stress levels varied, with 398 (61.3%) reporting normal stress, while anxiety ranged from 248 (38.2%) normal to 148 (22.8%) extremely severe. Conclusion This study emphasizes the importance of addressing sleep quality, mental health, and performance challenges among Sudanese healthcare professionals. It highlights the need for hospitals to implement measures enabling more time off, adequate sleep, and reduced on-call service days. Healthcare workers must recognize the significance of these factors for their well-being and patient care quality. The research outcomes can raise awareness about the necessity of regulating healthcare practitioners' working hours and ensuring adequate sleep.

Abstract Background Oculocutaneous albinism type1 (OCA1) is caused by the TYR gene's homozygous and compound heterozygous variants. TKFC gene variants cause triokinase & FMN cyclase deficiency syndrome with variable multisystemic disorders. Objectives To determine the potential disease-causing variants in two deceased patients presenting atypical OCA1 features by demonstrating three generations for a single family. The two deceased neonates had severe skeletal abnormalities and fatal hypertrophic cardiomyopathy. We also explored the potential mechanisms for the causative relationship between TKFC and multisystem disorders. Patients and methods Due to the new emerging symptoms that weren’t reported before with the TYR gene, the following methods were performed: Sanger sequencing for the TYR gene, followed by whole exome sequencing, co-segregation, and computational analyses. Results Extensive parental consanguinity was found, and consequently an autosomal recessive mode of inheritance was prioritized. Upon performing sequencing and segregation data, the following has been confirmed: positive co-segregation of nonsense homozygous NM_000372.5:c.346C > T p.(Arg116*) variant in TYR gene and multisystem disease-missense homozygous NM_015533.4:c.598G > A p.(Val200Ile) variant in TKFC gene in the two affected index patients who deceased due to hypertrophic cardiomyopathy. Using computational analysis, we found that c.598G > A p.(Val200Ile) pathogenicity has led to the failure of L2-K1 active site closure due to the potential differential fluctuation between valine and isoleucine residues. Subsequently, disruption of endogenous DHA phosphorylation was found. Two potential mechanisms exploring the causative relationship between TKFC gene and multisystem disorders have been suggested. Conclusions This study presented a first family with the co-existence of biallelic variants in TYR and TKFC genes associating severe skeletal abnormalities and lethal hypertrophic cardiomyopathy. Neither of these genes would have been pursued in the standard genetic counseling. Such discovery is paving the way for more efficient genetic counseling. Comparing TKFC results with literature data showed that our relevant expanded TKFC variant is the 3rd worldwide.

Abstract Background The use of IOUS is increasingly common in recent neurosurgical practice. IOUS has become very valuable in neurosurgery. It plays a key role in the localization of space-occupying lesion location and decreasing operation time and hence improves both surgical efficiency and safety. Ultrasound is very useful in the determination of the lesion location, its most superficial portion, and in differentiation between solid tumors and cystic components. Results Intraoperative ultrasonography has a significant edge over the other intraoperative aids for image guidance in brain surgery, especially in terms of independence, cost, and adaptability to multiple different clinical scenarios. Ultrasound-based neuro-navigation is an easy-to-use, fast, and safe technique of real-time imaging for various neurosurgical procedures. Conclusion We conclude that ultrasound-based neuro-navigation is an easy-to-use, fast, and safe technique of real-time imaging for various neurosurgical procedures.

Abstract Background Cardiac symptoms are a characteristic feature of chronic obstructive pulmonary disease (COPD), a disorder with lately achieved recognition as a systemic illness according to established standards. The research’s objective was aimed at investigating the transthoracic echocardiography role in assessing right ventricular (RV) dysfunction among individuals diagnosed with COPD, as well as to examine the potential correlation between blood pro B-type natriuretic peptide (BNP) concentrations + and this diagnostic procedure. Methods Arterial blood gasses, spirometry, echocardiography, and serum pro BNP were done for 80 COPD patients and 20 healthy smokers, and some echocardiographic parameters were correlated with degree of airflow limitation. Results 77.5% of COPD cases exhibited pulmonary hypertension (PHTN), and on classifying our COPD patients, it was found that 65% of patients in group II had PHTN and 90% of patients in group III had PHTN. Systolic pulmonary artery pressure (SPAP), mean pulmonary arterial pressure (MPAP), right ventricular mid diameter (RVMD), right ventricular basal diameter (RVBD), right ventricular longitudinal diameter (RVLD), right ventricular outflow tract (RVOT) above pulmonary and aortic valve, and tricuspid annular plane systolic excursion (TAPSE) along with RVEF exhibited a significant variance among all groups. A negative correlation was observed among forced expiratory volume (FEV) 1% and (RVMD as well as RVBD) and between Pro BNP and (TAPSE and RVEF). Conclusions PHTN was found in 77.5% of COPD patients and is negatively correlated with FEV1%. Serum pro BNP level exhibits a negative correlation with FEV1% in stable COPD patients.

Abstract Background & aims Chronic migraine poses a global health burden, particularly affecting young women, and has substantial societal implications. This study aimed to assess the efficacy of Greater Occipital Nerve Block (GONB) in individuals with chronic migraine, focusing on the impact of local anesthetics compared with placebo. Methods A meta-analysis and systematic review were conducted following the PRISMA principles and Cochrane Collaboration methods. Eligible studies included case-control, cohort, and randomized control trials in adults with chronic migraine, adhering to the International Classification of Headache Disorders, third edition (ICHD3). Primary efficacy outcomes included headache frequency, duration, and intensity along with safety assessments. Results Literature searches across multiple databases yielded eight studies for qualitative analysis, with five included in the final quantitative analysis. A remarkable reduction in headache intensity and frequency during the first and second months of treatment with GONB using local anesthetics compared to placebo has been reported. The incidence of adverse events did not differ significantly between the intervention and placebo groups. Conclusion The analysis emphasized the safety and efficacy of GONB, albeit with a cautious interpretation due to the limited number of studies and relatively small sample size. This study advocates for further research exploring various drugs, frequencies, and treatment plans to enhance the robustness and applicability of GONB for chronic migraine management.
