Abstract
PURPOSE Recent surveys indicate a significant increase in total caffeine intake among schoolchildren. Limited research has been published concerning the total intake of caffeine among schoolchildren in the Middle East and Gulf Cooperation Council (GCC) countries, including the UAE. METHODS This cross-sectional survey estimated the total caffeine intake from foods and beverages among 10,275 schoolchildren in the UAE. Caffeine intakes were related to the European Food Safety Authority's level of no safety concern (3.0 mg/kg BW) and level of effects on sleep (1.4 mg/kg BW). RESULTS More than half (56.2%) of the students consumed more than 100 mg (the upper limit allowed) of caffeine from dietary sources. High intake of caffeine (> 100 mg/day) was significantly associated (p = 0.001) with reduced sleep duration, difficulty falling asleep, infrequent exercising, using smart devices for more than 2 h a day, getting a lower GPA, skipping breakfast, eating fewer servings of vegetables than recommended, frequent consumption of fast food and more frequent snack consumption. CONCLUSION Excessive intake of caffeine from different dietary sources coexists with unhealthy dietary and lifestyle behaviors and sleep problems. Tailoring educational programs and intervention strategies is warranted to correct the unhealthy intake of caffeine and the associated unhealthy dietary and lifestyle behaviors among schoolchildren in the UAE.

Abstract
Background Consumption of caffeinated energy drinks (CED) has escalated during the last few years, especially among schoolchildren, with evident adverse health sequelae in this critical age group. Objective This study examined the prevalence of CED consumption and its associations with sleep, physical and mental health, and dietary and lifestyle habits among schoolchildren in the United Arab Emirates (UAE). Method A structured self-administered online questionnaire was developed and disseminated among schoolchildren aged 14-18 years, selected from schools of the seven emirates of the UAE. Results More than 4,500 (N= 4,648) responses received. A relatively low prevalence of CED consumption (20%) was found among schoolchildren in the UAE. However, those who reported CED consumption were more likely to report unhealthy dietary (skipping breakfast, frequent snacking, and eating fast foods, low fruit, and vegetable intake) and lifestyle behaviors (long screen time, poor sleep health), in addition to poor self-reported mental and physical health than non-users. CED consumption was significantly and variably associated with multiple sociodemographic factors such as students' nationality, parental companionship, sex, school type, education level (children's and parents'), daily allowance, academic performance, screen time, sleep quality parameters, self-reported physical and mental health, and parents' employment. Sources of knowledge about CED were social media (55%), friends/schoolmates (52%), and family members (52%). Students believed that CED constitute sugar (87%), caffeine (69%), artificial flavors (67%) sweeteners (54%), and stimulating components (43%). The majority (70%) of students reported that CED consumption increases the risks for heart disease, diabetes, high blood sugar (65%), addiction (64%), high blood pressure (59%), and obesity (57%). Conclusion These results offer important insights for health professionals, child health specialists, policymakers, and parents in the UAE regarding adolescents' attitudes, knowledge and behaviors toward CED consumption.

Abstract
Background:
Criteria for the diagnosis of malnutrition are still not uniform, and different
tools have been proposed. Global Leadership Initiative on Malnutrition (GLIM) is a newly
developed consensus diagnostic criteria tool.
Objective:
This study aims to determine the prevalence of malnutrition using the GLIM diagnostic
criteria upon admission to the hospital in the United Arab Emirates and evaluate the role muscle
strength can play in the accuracy of this diagnosis.
Methods:
This is a cross-sectional study that was carried out in two hospitals (Rashid Hospital,
Dubai, and Qassimi Hospital, Sharjah) in the United Arab Emirates. Low body mass index or significant
weight loss were used as phenotypic criteria; reduced food intake or the presence of disease
were used as etiological criteria. Muscle strength was measured using a handgrip strength
dynamometer as a supportive measure.
Results:
A total of 371 patients were recruited, of which a total of 103 patients (27.76%) were
diagnosed with malnutrition according to GLIM. The prevalence of low muscle strength was seen
in 60.47% of females (≤ 16.0 kg) and 61.82% males (≤ 27 kg). A total of 209 patients (58.22%)
were diagnosed with malnutrition, accounting for low muscle strength as a proxy for muscle mass
under the phenotypic criteria.
Conclusion:
The study opens a direction for future research to evaluate the feasibility and practicality
of the proposed GLIM criteria. It also opens a path for the validation of muscle strength and relevant
cut-off points across ages, genders, and ethnicities as a diagnostic criterion for malnutrition.

Abstract
PURPOSE Our primary objectives were to create a reliable, noninvasive method for three-dimensional morphometry of deep bony parameters within the sigmoid notch of the distal radius, to identify its morphological patterns, and to identify any significant variation between the left and the right wrists. Our secondary objectives were to obtain morphometric values that could represent our population and to identify any possible ethnic variations. METHODS Computed tomography scans of 102 wrists from 51 healthy individuals were analyzed using a virtualization software. Four anatomical parameters at the distal radius sigmoid notch, namely, the radius of curvature, depth, version angle, and sagittal slope were measured. Morphological patterns of the sigmoid notch surface were identified. The results were statistically analyzed to assess the reliability of the technique and were compared with previously published literature. RESULTS Comparing our findings with previously published values, our study revealed a slightly larger radius of curvature and sagittal slope, while revealing a smaller depth and version. We identified the S-type, C-type, and ski-slope morphological variants. The flat-face morphological variant, however, was not identified. The sigmoid notch at the left and right wrists were similar, except for the radius of curvature. CONCLUSION This study demonstrates a noninvasive, fast, reliable, and reproducible technique for analyzing the sigmoid notch of the distal radius. In wrist injuries with intact distal radius sigmoid notch but involving comminuted fractures of the ulnar head, ulnar head replacement may be indicated. In such cases, analysis of the ipsilateral intact sigmoid notch would allow us to prepare an ulnar head prosthesis of appropriate size.

Abstract
The OSIRIS study investigated efficacy and safety of simeprevir plus sofosbuvir for eight or 12 weeks in hepatitis C virus (HCV) genotype 4-infected patients with METAVIR F0-F4 fibrosis. Sixty-three patients (33 treatment-naïve and 30 peg-interferon/ribavirin (Peg-IFN/RBV)-experienced) enrolled in a partly randomized, open-label, multicentre, phase IIa study. Patients with F0-F3 fibrosis were randomized (1:1) into two groups (A1 and A2), stratified according to treatment experience and METAVIR score, to receive either eight weeks (Group A1, n=20) or 12 weeks (Group A2, n=20) of treatment. Patients with compensated cirrhosis (METAVIR F4) received 12 weeks of treatment (Group B, n=23). Treatment comprised simeprevir 150 mg and sofosbuvir 400 mg daily. The primary efficacy endpoint was sustained virologic response 12 weeks after planned end of treatment (SVR12). Safety and tolerability were assessed throughout. Overall, 92% (95% CI: 82-97) of patients achieved SVR12; 75% (15/20) in Group A1 and 100% in groups A2 and B. Patients who did not achieve SVR12 (n=5) experienced viral relapse during the first 32 days following treatment and were all prior Peg-IFN/RBV null responders. The most commonly reported treatment-emergent adverse events (TEAEs) were asymptomatic lipase increase (14%), pruritus (14%), headache (13%) and hyperbilirubinaemia (11%). No patients discontinued due to TEAEs. In conclusion, simeprevir plus sofosbuvir for 12 weeks achieved a 100% SVR rate in HCV genotype 4-infected patients with or without compensated cirrhosis (ClinicalTrials.gov: NCT02278419). The AE and laboratory profile were favourable and consistent with previous data for simeprevir plus sofosbuvir in eight- and 12-week regimens.

Abstract
Extracts from the stem bark of Streblus asper possess insecticidal activity against the fifth instar of Dysdercus cingulatus. Methanolic extract showed an LC(50) value of 5.56 microg/insect. Partition with chloroform increased the insecticidal activity (LC(50) 2.01 microg/insect). Three polyphenolic rich fractions were obtained from silica-gel column chromatography of the chloroform fraction and found to have noteworthy insecticidal activity (LC(50): 1.82 microg, 2.70 microg, 2.26 microg/insect) by topical application. This may provide a useful beginning for the development of biopesticides.

Abstract
HIV surveillance and screening programs were established at Khartoum Teaching Hospital (KTH) following the first identified HIV case diagnosed in a hemophiliac boy in November 1987. As of December 1995, 15 cases of symptomatic HIV infection have been observed in Sudanese children (< or = 16 years) at KTH. An HIV seroprevalence rate of 35.7% was documented in a group of 28 patients (adults and children) with various congenital coagulation defects. The postulated mode of transmission was through contaminated factor concentrate. Screening of 52,000 volunteer male blood donors (March, 1987-1989) showed an HIV-seroprevalence rate of 0.05%. Selected groups, including 1118 children admitted to KTH during the period 1985-1995, were screened for HIV infection. These included aseptic meningitis/encephalitis group (n = 52), high-risk group (n = 523), children with various chronic and malignant diseases (n = 181), and chronic blood recipients (n = 330). A group of 32 displaced homeless children who survived on the streets were also included. Overall, an HIV seroprevalence rate of 1.2% was established. Among the 15 children with symptomatic HIV infection, tuberculosis accounted for the majority of admissions (33.3%) followed by admission for recurrent infections (20.0%). Of the 13 children with nonparental mode of HIV transmission, a vertical mode was documented in 61.5%. The pattern of HIV infection in Greater Khartoum is similar to that in North Africa and the Middle East. However, the geographic influence of high endemicity in neighboring sub-Saharan countries might change it in the future.

Abstract
Seven children, six boys and a girl, aged from 2 to 15 years with proven myelofibrosis are reported. The clinical presentation in each of them was more or less similar with weight loss, moderate or low-grade fever, and abdominal distension with pain or discomfort for some months. They had hepatosplenomegaly. The spleens, enlarged to more than 6 cm below the costal margin, were smooth, firm and not tender. There was a variable degree of generalized lymphadenopathy. They were diagnosed as myelofibrosis associated with tuberculosis. The clinical response to anti-tuberculous chemotherapy was remarkable. Extensive search should be made for evidence of tuberculosis in children presenting with myelofibrosis.

Abstract
Eight patients with homozygous sickle cell anemia, 15 heterozygotes, and eight control individuals were investigated with respect to plasma concentrations of the inflammatory markers lysozyme and myeloperoxidase and the complement activation marker C3d. The patients showed significantly increased levels of myeloperoxidase and C3d, but not lysozyme, compared with the heterozygotes and the controls. The heterozygotes were also significantly different from the controls with regard to C3d concentration. The concentrations of myeloperoxidase and C3d in plasma showed a significant inverse correlation with the hemoglobin concentration. Myeloperoxidase and C3d showed a significant positive correlation. This suggests a role for the neutrophil and the complement system in the pathophysiology of sickle cell disease.
