Damage index in childhood-onset systemic lupus erythematosus in Egypt
<p>Abstract</p> <p>Background</p> <p>To investigate the prevalence of cumulative organ damage among Egyptian children with juvenile-onset systemic lupus erythematosus (jSLE) and the relationships between the organ damage and the demographic data, clinical variables, and disease activity.</p> <p>Methods</p> <p>A total of 148 patients with jSLE have been followed in the pediatric rheumatology clinic and section at Cairo University. These patients were evaluated by retrospective chart review. The organ system damage due to SLE was measured using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI). Risk factors for damage were also studied including demographic criteria as well as clinical and laboratory manifestations.</p> <p>Results</p> <p>Overall, 43.9% of the patients had damage within a mean of 6.57 Ā± 3.59 years of disease diagnosis. Neuropsychiatric (NPS-21%) and renal (16.9%) system involvement were observed most frequently, followed by cardiovascular (11.5%), skin (9.5%), pulmonary (6.1%), and ocular (4.8%), with a mean SDI score of 0.93 Ā± 1.37. In our study, the presence of neuropsychiatric manifestations at diagnosis showed the strongest association with the presence of later disease damage.</p> <p>The number of SLE diagnostic criteria at presentation was strongly associated with the total SDI score, and the renal damage was significantly more prevalent in patients with age at disease diagnosis below 10 years of age. A higher mean disease duration was found in patients with musculoskeletal damage.</p> <p>Conclusion</p> <p>We found that cumulative organ damage, as measured by the SDI, was present in 43.9% of Egyptian patients with juvenile-onset SLE. The damage was significantly more likely in patients who had more SLE diagnostic criteria at time of disease presentation and NPS manifestations at the time of diagnosis.</p
Levels of certain tumor markers as differential factors between bilharzial and non-biharzial bladder cancer among Egyptian patients
<p>Abstract</p> <p>Background/Objective</p> <p>Bladder cancer is the commonest type of malignant tumors as a result of schistosomaisis which is a major healthy problem in many subtropical developing countries. The aim of this study is to comparatively elucidate the underlying biochemical tumor markers in schistosomal bladder cancer versus non-schistosomal bladder cancer when compared to normal healthy ones.</p> <p>Methods</p> <p>This work was performed on tissue specimens from total 25 patients and serum samples from total 30 patients versus ten healthy individuals served as control. The investigated parameters in serum are: xanthine oxidase (XO), fructosamine, lactate dehydrogense (LDH), aspartate aminotransferase (AST), alanine aminotransferase (ALT), total proteins, essential and non- essential amino acids profile, hydroxyproline, total immunoglobulin E (IgE) and tumor necrosis factor alpha (TNF-<it>Ī±</it>). In addition, the current investigation also extended to study some markers in tumor bladder tissues including, pyruvate kinase enzyme (PK), lactate dehydrogenase (LDH), aspartate aminotransferase (AST) and alanine aminotransferase (ALT).</p> <p>Results</p> <p>Results showed that biharzial bladder cancer patients recored more significant elevation in serum XO, fructosamine, LDH, AST, ALT, hydroxyproline, IgE and TNF-<it>Ī± </it>than in bladder cancer patients when compared to control ones. While, in tissues there were significant increase in PK, LDH, AST & ALT activities of schistosomal bladder cancer than in bladder cancer as compared to control healthy patients.</p> <p>Conclusions</p> <p>It could be concluded that, bilharzial and non-bilharzial bladder cancer showed distinct biochemical profile of tumor development and progression which can be taken into consideration in diagnosis of bladder cancer.</p
Frequency and severity of ketoacidosis at diagnosis among childhood type 1 diabetes in Khartoum state, Sudan
Background: Diabetic ketoacidosis (DKA) is a potentially life
threatening acute complication of Type I diabetes mellitus (T1DM). This
study aimed to determine the frequency and clinical characteristics of
pediatric DKA at diagnosis of new-onset T1DM in Khartoum during 2000-
2017 period. Methods: The study was retrospective and involved review
of medical files of children (<15 years) with T1DM in the city
hospitals and diabetes centers. Results: The overall frequency of DKA
among T1DM children at onset of disease diagnosis was 17.6% (173/982).
The episodes of DKA increased from 26% in first 6- year period
(2000-2005) to 46.3% in the last 6-year period (2011-2012; p<0.001).
No significant difference in the frequency of DKA was observed
according to gender (p=0.9) and age (p=0.24). Compared to other age
groups, the severity of DKA (pH<7.1) was higher in pre-school
children (p<0.01). Approximately, 5% of patients were complicated
with cerebral edema with a mortality rate of 1.7%. Conclusion: The DKA
frequency at diagnosis of childhood T1DM in Khartoum was lower than
previous reports. In addition, the severity of DKA was high among
pre-school age children with a relatively high mortality rate when
compared to the global rate

Cardiometabolic Risk Factors and Its Association with Hyperandrogenemia Among Sudanese Reproductive Women with Polycystic Ovary Syndrome
Background: Risk factors for cardiovascular disease (CVD) are more common and frequently occur among PCOS women. The objective of this study was to evaluate atherogenic index of plasma (AIP) as a predictor of CVD and its association with hyperandrogenemia among PCOS women.
Methods and Results: This hospital-based study, conducted in Khartoum (Sudan) from October 2020 to September 2021, used a case-control design. The patients (n=150) were women with diagnosed PCOS, according to Rotterdam criteria. The controls were 150 infertile women who did not have PCOS. An ELISA reader (ASYS Expert Plus Microplate, Austria) was used to quantify serum insulin, luteinizing hormone (LH), follicle-stimulating hormone (FSH), and anti-Mullerian hormone (AMH) by indirect methods and total testosterone (TT) by competitive method during the follicular phase of the menstrual cycle. Serum samples of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and fasting plasma glucose (FPG) were assayed on the Cobas c311 system (Roche Diagnostics GmbH, Germany). The triglycerideāglucose index (TyGI) and TyGI-BMI, as a marker for insulin resistance (IR), were calculated. The logarithmically converted ratio of the molar concentrations of TG to HDL-C was used to determine the AIP. Low CVD risk was defined as 0.24.
PCOS women had a significant increase in BMI, compared to non-PCOS (P0.1.
PCOS women with hyperandrogenemia showed significantly increased AIP and decreased HDL-C. Additionally, about 73% of PCOS women with hyperandrogenemia had lower HDL-C, and 29.9% had a high risk of CVD (AIP>0.24).
A Spearman correlation revealed that PCOS womenās TT correlates positively with TC, TG, TyGI, and AIP and inversely correlates with HDL-C. AIP positively correlates with TT, TC, TyGI, and TyGI-BMI index.
Conclusion: Our data revealed a significant occurrence of hyperandrogenemia, dyslipidemia, AIP, and obesity, all of which are considered risk factors for CVD in PCOS women

Fundamental Role of Neurochemicals Aberration in the Pathogenesis of Autism Spectrum Disorders
AIM: The aim of this research was to establish the perturbation of reliable biomarkers implicated in the pathophysiology of autism to help in the early diagnosis and to be as targets in the treatment of autism spectrum disorders (ASDs) in children and to spotlight into the complex crosstalk between these biomarkers.
PATIENS AND METHODS: This study included 90 autistic children aged from 2 to 7 years old, who were classified into two groups, the atypical autism of 30 children and the childhood autism. The childhood autism group was further divided into mild-moderate autism group and severe autism group each of 30 children. The control group included 30 matched healthy children. All the participants were subjected to full psychiatric examinations, psychological investigations, and biochemical measurements, including gamma-aminobutaric acid (GABA), serotonin, dopamine (DA) in plasma, and brain-derived neurotrophic factor (BDNF) in serum.
RESULTS: The autistic groups showed a highly significant increase in GABA, serotonin, DA, and BDNF levels compared to the control. Of note, the levels of GABA, DA, and BDNF were significantly increased with the increased disease severity. Furthermore, a significant positive correlation between BDNF levels and both GABA and DA levels in the childhood autism group has been recorded.
CONCLUSION: The present clinical setting provides new insight into the fundamental role of BDNF in the brain of autistic children as any alterations of its level due to GABA increment cause change in serotonin and DA levels which have empirical evidence in the pathophysiology of ASD. The results received in this research, create a fertile base for the setup of particular targets in the intervention of this ailment
Wax co-cracking synergism of high density polyethylene to alternative fuels
AbstractAttempts have been made to understand the thermal degradation of high density polyethylene (HDPE) and their combined co-cracking using different ratios of HDPE and petroleum wax under nitrogen atmosphere. We have conducted the experiments using HDPE as the raw material and petroleum wax as co-feed by at 400 and 450Ā°C reaction temperatures. The product distribution was noted along with reaction time of 0.5ā3h for the degradation. Thermal gravimetric analysis (TGA) technique was used to measure the weight change of the feedstock as a function of temperature and time. Differential scanning calorimetry (DSC) was used to determine the degradation temperature. Products were characterized using gas chromatography (GC) and infrared spectroscopy (FTIR), some other standard physical methods were used to determine the main properties of the liquid products. Results show that the mixed plastic-wax samples could be converted into gases, gasoline, and middle distillate depending upon the composition of feed polymer/wax ratio. It was found that the products mostly consisted of paraffin and olefin compounds, with carbon numbers of C1āC4, C5āC9 and C10āC19 in the case of gases, gasoline and middle distillate respectively
DJELOVANJE UMJETNIH GNOJIVA NA KEMIJSKU ANALIZU I SASTAV AMINOKISELINA I MASNIH KISELINA SUDANSKOG GENOTIPA SOJE
The impact of fertilizer on chemical analysis, amino acid and fatty acid composition of soybean (Glycine max L merril) Sudanese local genotype was studied. A field experiment was conducted for two consecutive seasons (2009-2010 and 2010-2011) on the demonstration farm of the College of Agricultural studies, Sudan University of Science and Technology at Shambat. The experiment was laid out in a randomized complete block design with four replicates. The fertilizer treatments consisted of three types: Urea (180 kg/ha), NP (361kg/ha), compost (1904.76 kg/ha) and then control. The results showed that fertilizer treatments had no significant difference in proximate analysis of soybean seeds except in fibber. In fatty acid, control and nitrogen treatments gave the highest percentage of palmitic acid. NP and compost gave highest effect in linoleic acid and compost gave highest effect in polyunsaturated fatty acids. As general compost treatment gave the lowest effect in all amino acids and the highest effect in minerals. Control gave the highest effect in all amino acids. The application of nitrogen, NP and compost fertilizers for soybean significantly increased number of seeds/plant, weight of seedsplant and seeds yield. The results also showed that urea fertilizer increased protein and ash content, while NP increased oil and carbohydrate contents. Compost increased all the minerals, but there was no effect on fatty and amino acid composition.Istraživano je djelovanje umjetnog gnojiva na kemijsku analizu, sastav amino kiselina i masnih kiselina soje (Glycine max L.merril) lokalnog sudanskog genotipa. Proveden je terenski pokus tijekom dvije uzastopne sezone (2009. ā 2010. i 2010. -2011.) na oglednoj farmi Visoke poljoprivredne Å”kole Sudanskog SveuÄiliÅ”ta znanosti i tehnologije u Shambatu. Pokus je postavljen u sluÄajnom potpunom bloku u Äetiri ponavljanja. Tretmani s umjetnim gnojivom sastojali su se od tri tipa: Urea (180 kg/ha), NP (361 kg/ha) i kompost (1904,76 kg/ha) te kontrola. Rezultati su pokazali da se tretiranje umjetnim gnojivom nije znaÄajno razlikovalo u neposrednoj analizi sjemena soje osim u vlaknu. U masnoj kiselini, kontroli i tretmanu s duÅ”ikom dobiven je najviÅ”i postotak palminske kiseline. NP i kompost imali su najveÄi uÄinak u polunezasiÄenim masnim kiselinama. OpÄenito, tretman s kompostom imao je najslabiji uÄinak u svim aminokiselinama, a najviÅ”i uÄinak u mineralima. Kontrola je pokazala najviÅ”i uÄinak u svim aminokiselinama. Primjena duÅ”ika, NP i komposta znaÄajno je poveÄala broj sjemenki po biljci, težinu sjemenki po biljci i prinos sjemena. Rezultati su takoÄer pokazali da je urea kao gnojivo poveÄala sadržaj duÅ”ika i pepela dok je NP poveÄao sadržaj ulja i ugljikohidrata. Kompost je poveÄao sve minerale ali nije djelovao na sastav amino i masnih kiselina
