Childhood asthma has been increasing in Sudan, with a 13– 16% prevalence among Khartoum school children. To achieve and maintain good asthma control, proper diagnosis, assessment of severity, and appropriate medication administration are crucial, with phenotyping being a key factor in determining patients’ specific treatment.Objective: To study the frequency of severe asthma and the distribution of its different phenotypes and to investigate associations between age and gender and different phenotypes of asthma.Methodology: This descriptive cross-sectional hospital-based study was conducted in the Asthma Clinic of Mohamed Al-Amin Hamid Pediatrics Hospital. It included 229 patients who were presented to the clinic from September 2021 to April 2022. Data were collected from the patients and/or their caregivers using a modified validated standard questionnaire and were analyzed using SPSS version 26.0. A p-value of 0.05 or less was considered statistically significant.Results: In this study of 229 participants, 14.4% had severe asthma, with 44.5% and 41% exhibiting mild and moderate asthma, respectively. Most were effectively managed in steps 2 or 3. The cohort, primarily aged 5 or younger (40.2%) with a male majority (62%), showed a mean diagnosis age of 2.9 ± 2.8 years. Impressively, 90% maintained well-controlled asthma. Within severe asthma cases (87% atopic), 39.4% represented a severe allergic asthma phenotype. Elevated eosinophil counts were noted in 45.5% (serum) and 78.8% (sputum cytology), while 57.6% had normal serum IgE levels. The predominant symptom pattern in severe asthma was episodic multi-trigger wheezing (48.5%). Age and gender displayed no significant association with severe asthma phenotype.Conclusion: This study reveals a concerning rise in childhood asthma prevalence in Sudan, emphasizing the importance of tailored treatment strategies. Severe asthma, characterized by atopic eosinophilic involvement, necessitates targeted interventions in pediatric asthma care for specific phenotypes.Keywords: asthma, pediatrics, respiratory system, chronic obstructive pulmonary diseases, Sudan

Non-alcoholic steatohepatitis (NASH) is a more dangerous form of chronic non-alcoholic fatty liver disease (NAFLD). In the current investigation, the influence of citicoline on high-fat diet (HFD)-induced NASH was examined, both alone and in combination with Lactobacillus (probiotic). NASH was induced by feeding HFD (10% sugar, 10% lard stearin, 2% cholesterol, and 0.5% cholic acid) to rats for 13 weeks and received single i.p. injection of streptozotocin (STZ, 30 mg/kg) after 4 weeks. Citicoline was given at two dose levels (250 mg and 500 mg, i.p.) at the beginning of the sixth week, and in combination with an oral suspension of Lactobacillus every day for eight weeks until the study's conclusion. HFD/STZ induced steatohepatitis as shown by histopathological changes, elevated serum liver enzymes, serum hyperlipidemia and hepatic fat accumulation. Moreover, HFD convinced oxidative stress by increased lipid peroxidation marker (MDA) and decreased antioxidant enzymes (GSH and TAC). Upregulation of TLR4/NF-kB and the downstream inflammatory cascade (TNF-α, and IL-6) as well as Pentaraxin, fetuin-B and apoptotic markers (caspase-3 and Bax) were observed. NASH rats also had massive increase in Bacteroides spp., Fusobacterium spp., E. coli, Clostridium spp., Providencia spp., Prevotella interrmedia, and P. gingivalis while remarkable drop in Bifidobacteria spp. and Lactobacillus spp. Co-treatment with citicoline alone and with Lactobacillus improve histopathological NASH outcomes and reversed all of these molecular pathological alterations linked to NASH via upregulating the expression of Nrf2/HO-1 and downregulating TLR4/NF-kB signaling pathways. These results suggest that citicoline and lactobacillus may represent new hepatoprotective strategies against NASH progression., (© 2023. The Author(s).)

Background: Ward rounds are a cornerstone in the educational experience of junior doctors and an essential part of teaching patient care. Here, we aimed to assess the doctors' perception of ward rounds as an educational opportunity and to identify the obstacles faced in conducting a proper ward round in Sudanese hospitals., Method: A cross-sectional study was conducted from the 15 th to the 30 th of January 2022 among house officers, medical officers, and registrars in about 50 teaching and referral hospitals in Sudan. House officers and medical officers were considered the learners, while specialist registrars were considered the teachers. Doctors' perceptions were assessed using an online questionnaire, with a 5-level Likert scale to answer questions., Results: A total of 2,011 doctors participated in this study (882 house officers, 697 medical officers, and 432 registrars). The participants were aged 26.9 ± 3.2 years, and females constituted about 60% of the sample. An average of 3.1 ± 6.8 ward rounds were conducted per week in our hospitals, with 11.1 ± 20.3 h spent on ward rounds per week. Most doctors agreed that ward rounds are suitable for teaching patient management (91.3%) and diagnostic investigations (89.1%). Almost all the doctors agreed that being interested in teaching (95.1%) and communicating appropriately with the patients (94.7%) make a good teacher in ward rounds. Furthermore, nearly all the doctors agreed that being interested in learning (94.3%) and communicating appropriately with the teacher (94.5%) make a good student on ward rounds. About 92.8% of the doctors stated that the quality of ward rounds could be improved. The most frequently reported obstacles faced during ward rounds were the noise (70%) and lack of privacy (77%) in the ward environment., Conclusion: Ward rounds have a special value in teaching patient diagnosis and management. Being interested in teaching/learning and having good communication skills were the two major criteria that make a good teacher/learner. Unfortunately, ward rounds are faced with obstacles related to the ward environment. It is mandatory to ensure the quality of both ward rounds' teaching and environment to optimize the educational value and subsequently improve patient care practice., (© 2023. The Author(s).)
