Low birth weight (LBW) is a major predictor of child mortality and morbidity. The objectives of this study are to determine the proportion and risk factors of LBW. A matched case-control study was conducted at Omdurman Maternity Hospital, Sudan. The study population consisted of all babies delivered in August 2016 excluding stillbirths, multiple births, and babies with insufficient data. All LBW neonates were selected using total coverage sampling as cases and matched on babies' gender with randomly selected normal birth weights as controls. The sample size was 350 babies; 175 test cases and 175 control cases. Data were collected from hospital records and six risk factors were tested: mother age, parity, gravidity, mode of delivery, hypertensive disorders, and diabetes mellitus. The proportion of LBW was 10.8% of the total number of delivered neonates which is 2,938. The bivariate analysis identified that younger mother age ( p = 0.03) and hypertension ( p = 0.02) were significantly associated with LBW while other factors were found statistically insignificant. Multivariable conditional logistic regression revealed that hypertensive disorders in pregnancy increase the risk for LBW almost three times [Adjusted OR = 2.98 (95% CI: 1.23-7.22), p = 0.02]. We found that hypertension is an independent risk factor for LBW. The proportion of LBWcan be reduced if hypertension is controlled by providing simple measures like proper antenatal care and health education for pregnant women., Competing Interests: The authors declare no conflicts of interest., (Copyright © Sudanese Association of Pediatricians.)

Objective: Still's disease is more frequently observed in the paediatric context, but a delayed onset is not exceptional both in the adulthood and in the elderly. However, whether paediatric-onset, adult-onset and elderly-onset Still's disease represent expressions of the same disease continuum or different clinical entities is still a matter of controversy. The aim of this study is to search for any differences in demographic, clinical features and response to treatment between pediatric-onset, adult-onset and elderly-onset Still's disease., Methods: Subjects included in this study were drawn from the International AutoInflammatory Disease Alliance Network registry for patients with Still's disease., Results: A total of 411 patients suffering from Still's disease were enrolled; the disease occurred in the childhood in 65 (15.8%) patients, in the adult 314 (76.4%) patients and in the elderly in 32 (7.8%) patients. No statistically significant differences at post-hoc analysis were observed in demographic features of the disease between pediatric-onset, adult-onset and elderly-onset Still's disease. The salmon-coloured skin rash (p=0.004), arthritis (p=0.009) and abdominal pain (p=0.007) resulted significantly more frequent among paediatric patients than in adult cases, while pleuritis (p=0.015) and arthralgia (p<0.0001) were significantly more frequent among elderly-onset patients compared with paediatric-onset subjects. Regarding laboratory data, thrombocytosis was significantly more frequent among paediatric patients onset compared with adult-onset subjects (p<0.0001), while thrombocytopenia was more frequent among elderly-onset patients although statistical significance was only bordered. No substantial differences were observed in the response to treatments., Conclusions: Despite some minor difference between groups, overall, demographic, clinical, laboratory and treatments aspects of Still's disease were similarly observed in patients at all ages. This supports that pediatric-onset, adult-onset and elderly-onset Still's disease is the same clinical condition arising in different ages., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Objective: To evaluate the potential role of Streptococcus salivarius K12 (SSK12) in controlling febrile flares in patients with Periodic Fever, Aphthous stomatitis, Pharyngitis, and cervical Adenitis (PFAPA) syndrome. Further aims were to assess the impact of SSK12 on (i) flare duration, (ii) variation in the degree of the highest body temperature during flares, (iii) steroid-sparing effect, and (iv) change of PFAPA accompanying symptoms before and after SSK12 introduction., Patients and Methods: The medical charts from 85 pediatric patients with PFAPA syndrome (49 males and 36 females) enrolled in the AIDA registry and treated with SSK12 for a median period of 6.00 ± 7.00 months in the period between September 2017 and May 2022 were examined. Children recruited had a median time of disease duration of 19.00 ± 28.00 months., Results: The number of febrile flares significantly decreased comparing the 12 months before [median (IQR), 13.00 (6.00)] and after SSK12 initiation [median (IQR), 5.50 (8.00), p < 0.001]. The duration of fever was significantly reduced from 4.00 (2.00) days to 2.00 (2.00) days [ p < 0.001]. Similarly, the highest temperature in°C was found significantly lower in the last follow-up assessment [median (IQR), 39.00 (1.00)] compared to the period prior to SSK12 start [median (IQR), 40.00 (1.00), p < 0.001]. Steroid load (mg/year) of betamethasone (or any equivalent steroid) significantly decreased between 12 months before treatment with SSK12 [median (IQR), 5.00 (8.00) mg/year] and the last follow-up visit [median (IQR), 2.00 (4.00) mg/year, p < 0.001]. The number of patients experiencing symptoms including pharyngitis/tonsillitis ( p < 0.001), oral aphthae ( p < 0.001) and cervical lymphadenopathy ( p < 0.001) significantly decreased following SSK12., Conclusion: SSK12 prophylaxis given for at least 6.00 months was found to reduce febrile flares of PFAPA syndrome: in particular, it halved the total number per year of fever flares, shortened the duration of the single febrile episode, lowered body temperature by 1°C in the febrile flare, provided a steroid-sparing effect, and significantly reduced the accompanying symptoms related to the syndrome., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 La Torre, Sota, Insalaco, Conti, Del Giudice, Lubrano, Breda, Maggio, Civino, Mastrorilli, Loconte, Natale, Celani, Romeo, Patroniti, Gentile, Vitale, Caggiano, Gaggiano, Diomeda, Cattalini, Lopalco, Emmi, Parronchi, Gentileschi, Cardinale, Aragona, Shahram, Marino, Barone, Moscheo, Ozkiziltas, Carubbi, Alahmed, Iezzi, Ogunjimi, Mauro, Tarsia, Mahmoud, Giardini, Sfikakis, Laskari, Więsik-Szewczyk, Hernández-Rodríguez, Frediani, Gómez-Caverzaschi, Tufan, Almaghlouth, Balistreri, Ragab, Fabiani, Cantarini and Rigante.)

Khalawi are non-governmental, traditional educational boarding institutions, widely scattered in Sudan. Many Khalawi are resource-limited with deficient feeding and poor housing conditions, which could seriously affect the students' health. A cross-sectional study was conducted, involving all students of a Khalwa in Sharg Al-Neel Locality, Khartoum State. Demographic data were collected using a structured questionnaire with anthropometric measurements, along with laboratory and clinical assessments for anaemia. The dietary behaviours of students were also assessed using Global School-based Health Survey. Statistical analysis was conducted using SPSS software. A total of 131 students were included in this study. Their mean age was 13.7 ± 2.7 years, nearly half of them were from Darfur State in western Sudan, and the majority of them are primary school students. Upon assessment, many displayed serious symptoms and signs of anaemia namely: conjunctival pallor, palmar pallor, fatigability, lightheadedness and palpitation. Based on their haemoglobin testing, 95% were anemic and 24% had severe anaemia. Although 63.6% of them had normal body mass index (4.5%), 11.4%, were found 'severely thin' and 'thin', respectively. Regarding their dietary habits, 46.8% of them consumed milk or milk products less than one time per day, while 20.6% did not consume milk products in the past 30 days. Moreover, 39.4%, 44.9% and 39.4% did not consume any vegetables, fruits or fruit juice, respectively, in the past month. Students of Khalwa displayed poor dietary habits, which resulted in nutritional deficiencies. Programmes must be directed towards improving the quality of diet provided at these schools., Competing Interests: The authors declare that they have no competing interests., (Copyright © Sudanese Association of Pediatricians.)

Purpose of the present paper is to point out the design, development and deployment of the AutoInflammatory Disease Alliance (AIDA) International Registry dedicated to pediatric and adult patients with Behçet's disease (BD). The Registry is a clinical physician-driven non-population- and electronic-based instrument implemented for the retrospective and prospective collection of real-life data about demographics, clinical, therapeutic, laboratory, instrumental and socioeconomic information from BD patients; the Registry is based on the Research Electronic Data Capture (REDCap) tool, which is thought to collect standardised information for clinical real-life research, and has been realised to change over time according to future scientific acquisitions and potentially communicate with other existing and future Registries dedicated to BD. Starting from January 31st, 2021, to February 7th, 2022, 110 centres from 23 countries in 4 continents have been involved. Fifty-four of these have already obtained the approval from their local Ethics Committees. Currently, the platform counts 290 users (111 Principal Investigators, 175 Site Investigators, 2 Lead Investigators, and 2 data managers). The Registry collects baseline and follow-up data using 5993 fields organised into 16 instruments, including patient's demographics, history, clinical manifestations and symptoms, trigger/risk factors, therapies and healthcare access. The development of the AIDA International Registry for BD patients will facilitate the collection of standardised data leading to real-world evidence, enabling international multicentre collaborative research through data sharing, international consultation, dissemination of knowledge, inclusion of patients and families, and ultimately optimisation of scientific efforts and implementation of standardised care.Trial registration NCT05200715 in 21/01/2022., (© 2022.

Objective: The aim of this paper is to present the AutoInflammatory Disease Alliance (AIDA) international Registry dedicated to Vacuoles, E1 enzyme, X-linked, Autoinflammatory, Somatic (VEXAS) syndrome, describing its design, construction, and modalities of dissemination., Methods: This Registry is a clinical, physician-driven, population- and electronic-based instrument designed for the retrospective and prospective collection of real-life data. Data gathering is based on the Research Electronic Data Capture (REDCap) tool and is intended to obtain real-world evidence for daily patients' management. The Registry may potentially communicate with other on-line tools dedicated to VEXAS syndrome, thus enhancing international collaboration and data sharing for research purposes. The Registry is practical enough to be easily modified to meet future needs regarding VEXAS syndrome., Results: To date (April 22 nd , 2022), 113 Centers from 23 Countries in 4 continents have been involved; 324 users (114 Principal Investigators, 205 Site Investigators, 2 Lead Investigators, and 3 data managers) are currently able to access the registry for data entry (or data sharing) and collection. The Registry includes 4,952 fields organized into 18 instruments designed to fully describe patient's details about demographics, clinical manifestations, symptoms, histologic details about skin and bone marrow biopsies and aspirate, laboratory features, complications, comorbidities, therapies, and healthcare access., Conclusion: This international Registry for patients with VEXAS syndrome will allow the achievement of a comprehensive knowledge about this new disease, with the final goal to obtain real-world evidence for daily clinical practice, especially in relation to the comprehension of this disease about the natural history and the possible therapeutic approaches.

Khalawi are one of the most ancient non-governmental educational institutions that are commonly found all over Sudan playing a major role in the Sudanese society. The majority of Khalwa students are children. This study was part of a mixed methods project, conducted by Khartoum Medical Students' Association, aiming to investigate the health status of Khalwa students. It is a cross-sectional study carried out in Mustafa Alfadni Khalwa, Sharg Al-Neel suburb in Khartoum State. The participants were clinically assessed by a doctor and data were collected by using a data entry tool made specially to screen for major infectious diseases among students. The results showed a mean age of 13.7 years. Most of the students (47.7%) were originally from Darfur, and 27.5% of them had only Khalwa education. Respiratory clinic results revealed that 10% were complaining of cough, and 3.4% were diagnosed with pneumonia. Additionally, 44.6% of the students had tinea capitis and 21% had scabies. On examination, 2.3% and 1.1% had mild splenomegaly and hepatomegaly, respectively. Infectious conjunctivitis and trachoma were reported among 11.7% and 10.9%, respectively. Blood films for malaria were positive in 51.3%. Macroscopic and microscopic haematuria was evident among 13.4% and 10.8% of the participants, respectively. Stool examination results showed that 1.4% of the students had worms, 1.5% had ova and 18.8% had red blood cells in stools. Infectious diseases are very common among Khalwa students and their living environment is facilitating the transmission of these diseases. Agent control and sanitation improvement are crucial to decrease such infectious diseases., Competing Interests: The authors have no conflict of interest to declare., (Copyright © Sudanese Association of Pediatricians.)

We aimed to investigate the acute and chronic effects of carvedilol on insulin resistance in high-fructose, high-fat diet (HFrHFD) - fed mice and the implication of the β-arrestin2 pathway. The acute effect of carvedilol (10 mg/kg, i.p.) on glucose tolerance and hepatic lipid signaling in normal and insulin resistant mice was investigated. Then, the chronic effect of carvedilol on insulin resistance and dyslipidemia in HFrHFD-fed mice was examined. Changes in β-arrestin2 and its downstream signals in liver, skeletal muscle, and adipose tissue were measured. This involved measuring phosphatidylinositol 4,5-bisphosphate (PIP2) and diacylglycerol (DAG) levels and protein kinase B (AKT) activity. Carvedilol acutely reduced fasting blood glucose levels in both normal and insulin resistant mice without significantly affecting the glucose tolerance. These acute effects were associated with increased hepatic PIP2 but decreased hepatic DAG levels. Chronic administration of carvedilol significantly ameliorated insulin resistance and dyslipidemia in HFrHFD-fed mice. These chronic effects were associated with increased β-arrestin2, PIP2, and AKT activity levels but decreased DAG levels in the classical insulin target tissues. In conclusion, carvedilol acutely maintains glucose homeostasis and chronically ameliorates insulin resistance and dyslipidemia in HFrHFD-fed mice. The insulin sensitizing effects of carvedilol are highly correlated with the upregulation of β-arrestin2 pathway.

Aims: β-Arrestin2 signaling has emerged as a promising therapeutic target for the management of insulin resistance and related complications. Moreover, recent studies have shown that certain G protein-coupled receptor (GPCR) ligands can modulate β-arrestin2 signaling. The current study examined the effects of the β-blocker propranolol and a low dose of the agonist isoproterenol (L-D-ISOPROT) on β-arrestin2 signaling, insulin resistance, and cardiac remodeling in high-fructose, high-fat diet (HFrHFD)-fed mice. In addition, the effects of these agents were compared to those of the clinical antidiabetic agent, metformin., Materials and Methods: Insulin resistance was induced by HFrHFD feeding for 16 weeks. Mice were then randomly allocated to groups receiving propranolol, L-D-ISOPROT, metformin, or vehicle (control) for 4 weeks starting on week 13 of HFrHFD feeding. Survival rate, body weight, visceral fat weight, blood glucose, serum insulin, insulin resistance index, hepatic β-arrestin2 signaling, heart weight, left and right ventricular thicknesses, cardiac fibrosis severity, serum endothelin-1, cardiac cardiotrophin-1, and cardiac β-arrestin2 signaling were then compared among groups., Key Findings: HFrHFD for 16 weeks significantly increased insulin resistance index, cardiac fibrosis area, and serum endothelin-1, and reduced hepatic β-arrestin2 signaling, cardiac cardiotrophin-1, and cardiac β-arrestin2 signaling without significant changes in survival rate, body weight, visceral fat weight, heart weight, or left and right ventricular thicknesses. All three drugs reduced insulin resistance and cardiac remodeling parameters and enhanced β-arrestin2 signaling with variable efficacies., Significance: Propranolol and L-D-ISOPROT, like metformin, can reduce insulin-resistance and cardiac remodeling in HFrHFD-fed mice, possibly by upregulating β-arrestin2 signaling activity. Therefore, β-arrestin2-signaling modulation might be a promising strategy for insulin-resistance treatment., (Copyright © 2021 Elsevier Inc. All rights reserved.)
