Controlling hybrid nonlinearities in transparent conducting oxides via two-colour excitation.

Nanophotonics and metamaterials have revolutionized the way we think about optical space (ɛ,µ), enabling us to engineer the refractive index almost at will, to confine light to the smallest of the volumes, and to manipulate optical signals with extremely small footprints and energy requirements. Significant efforts are now devoted to finding suitable materials and strategies for the dynamic control of the optical properties. Transparent conductive oxides exhibit large ultrafast nonlinearities under both interband and intraband excitations. Here we show that combining these two effects in aluminium-doped zinc oxide via a two-colour laser field discloses new material functionalities. Owing to the independence of the two nonlinearities, the ultrafast temporal dynamics of the material permittivity can be designed by acting on the amplitude and delay of the two fields. We demonstrate the potential applications of this novel degree of freedom by dynamically addressing the modulation bandwidth and optical spectral tuning of a probe optical pulse.

Prevalence of childhood obesity in the state of Kuwait.

BACKGROUND: Overweight and obesity have reached an epidemic in Kuwait, with the highest rate of adult obesity in the region. National estimates of childhood obesity in Kuwait are scarce. The purpose of this study is to evaluate the prevalence of overweight and obesity among school children in Kuwait. METHODS: This is a cross-sectional study of a representative sample of 6-18 years old school children, randomly selected from 244 schools in Kuwait. Anthropometric data was measured from 6574 students in September 2012-June 2013. Overweight and obesity have been defined in accordance with the Centres for Disease Control and Prevention (CDC), International Obesity Task Force (IOTF) and World Health Organization (WHO) 2007 criteria. RESULTS: The prevalence estimate overweight was based on the three different systems (CDC = 17.7%, IOTF = 23.3%, WHO = 21.6%). The prevalence of obesity was (CDC = 33.9%, IOTF = 28.2%, WHO = 30.5%). Boys had a higher percentage of obesity regardless of the classification system used. CONCLUSIONS: The prevalence of childhood obesity is alarmingly high in the State of Kuwait and exceeds the prevalence rates reported from neighbouring countries and from North America.

In vitro conservation of embryogenic cultures of date palm using osmotic mediated growth agents.

This study was carried out to investigate the effect of mannitol, sorbitol and sucrose as osmotic agents on in vitro conservation of embryogenic cultures of date palm (Phoenix dactylifera, L.) Bartamoda and Sakkoty cultivars. Embryogenic cultures was obtained using MS medium supplemented with 10 mg/l 2,4-dichlorophenoxy acetic acid (2,4-D) and 3 mg/l isopentenyl adenine (2iP). Among the three types of osmotic substances used for slow growth conservation, sucrose at all concentrations gave the highest percentage of survival with Sakkoty cultivar. However, addition of 40 g/l or 60 g/l mannitol and 20 g/l sorbitol showed the highest percentage of survival percentage with Bartamoda cultivar. The different sucrose concentrations caused higher numbers of germinated embryos of the two cultivars compared with mannitol or sorbitol. Also, the number of germinated embryos was increased with increasing the storage periods till the ninth month. Genetic stability was determined using random amplified polymorphic DNA (RAPD) analysis. There were no clear genetic differences between the two osmotic agents used for preservation. The preserved cultures of Sakkoty cultivar gave the high percent of similarity while Bartamoda cultivar gave low percent of similarity. From the obtained results we can recommend using 40 g/l mannitol or 20 g/l sorbitol for in vitro preservation of Bartamoda cultivar of date palm and 20 g/l of sucrose for Sakkoty cultivar.

Prevalence of thyroid autoantibodies in children, adolescents and young adults with type 1 diabetes in Kuwait.

OBJECTIVE: To investigate the prevalence of thyroid autoimmunity among children and adolescents with type 1 diabetes in Kuwait. SUBJECTS AND METHODS: In a mixed cross-sectional and longitudinal study, anti-thyroid peroxidase (anti-TPO) and anti-thyroglobulin (anti-TG) were measured in 232 subjects (118 males and 114 females) with type 1 diabetes. RESULTS: The mean age of the total study population was 10.9 ± 3.6 years (range 1-21), and the median diabetes duration was 3.9 years (range 0-16). At the initial screening, 57 out of 232 (24.6%) patients had positive antibodies, and of the remaining 175 patients, who were antibody negative,131 (74.3%) were followed up for 4-9 years. 23 out of these 131 (17.7%) patients became antibody positive, with a cumulative prevalence of elevated antibodies of 34.5%. Anti-TPO was present in 34 (14.7%), anti-TG in 23 (9.9%) and both antibodies in 23 (9.9%) patients. Thyroid antibodies presented early within the first 5 years of the onset of diabetes (63.2 vs. 36.8%, p < 0.05). The prevalence of elevated thyroid antibodies increased after the onset of puberty in both females and males (p < 0.0001). A total of 58.7% of the patients with positive antibodies were females compared to 41% males (p < 0.0001). The basal thyroid-stimulating hormone was higher in subjects with positive antibodies (5.1 ± 10.7 mIU/l) compared to those who were antibody negative (1.79 ± 0.87 mIU/l, p < 0.001). Furthermore, 30 out of 232 (12.9%) patients developed thyroid dysfunction. CONCLUSION: In this study, a high prevalence of thyroid autoimmune antibodies was found in patients either at the onset of type 1 diabetes or within the 4-9 years of follow-up.

The Kuwait-Scotland eHealth Innovation Network (KSeHIN): a sustainable approach to quality improvement in healthcare.

BACKGROUND: The rising prevalence of obesity and diabetes in Kuwait represents a significant challenge for the country's healthcare system. Diabetes care in Scotland has improved by adopting a system of managed clinical networks supported by a national informatics platform. In 2010, a Kuwait-Dundee collaboration was established with a view to transforming diabetes care in Kuwait. This paper describes the significant progress that has been made to date. METHODS: The Kuwait-Scotland eHealth Innovation Network (KSeHIN) is a partnership among health, education, industry and government. KSeHIN aims to deliver a package of clinical service development, education (including a formal postgraduate programme and continuing professional development) and research underpinned by a comprehensive informatics system. RESULTS: The informatics system includes a disease registry for children and adults with diabetes. At the patient level, the system provides an overview of clinical and operational data. At the population level, users view key performance indicators based on national standards of diabetes care established by KSeHIN. The national childhood registry (CODeR) accumulates approximately 300 children a year. The adult registry (KHN), implemented in four primary healthcare centres in 2013, has approximately 4000 registered patients, most of whom are not yet meeting national clinical targets. A credit-bearing postgraduate educational programme provides module-based teaching and workplace-based projects. In addition, a new clinical skills centre provides simulator-based training. Over 150 masters students from throughout Kuwait are enrolled and over 400 work-based projects have been completed to date. CONCLUSION: KSeHIN represents a successful collaboration between multiple stakeholders working across traditional boundaries. It is targeting patient outcomes, system performance and professional development to provide a sustainable transformation in the quality of diabetes healthcare for the growing population of Kuwaitis with diabetes in Kuwait.

Further evidence for the rising incidence of childhood Type 1 diabetes in Kuwait.

AIMS: To provide age-gender standardized incidence rate, temporal trend and seasonal variation of Type 1 diabetes in Kuwaiti children aged < or = 14 years. METHODS: Data were prospectively collected over a period of 6 years (1992-1997) according to the DiaMond Project protocol using the capture-recapture method of ascertainment. RESULTS: Data ascertainment varied between 90% and 96%. The incidence rate of Type 1 diabetes was 20.1 per 100,000 children 0-14 years (95% confidence interval (CI) 18.0-22.1); age-standardized incidence rate 20.9 (95% CI 18.8-23.0). The incidence rate among boys, 21.1 per 100,000 (95% CI 18.1-24.1) was slightly higher than that among girls, 19.0 per 100,000 (95% CI 16.1-21.8). The age-standardized incidence rate was 21.9 (95% CI 18.9-24.8) in boys, and 19.9 (95 CI 17.1-22.8) in girls. Incidence rates increased with age in both sexes (boys chi(2) for linear trend = 13.5, P < 0.001; and for girls chi(2) = 27.8, P < 0.0001). There was a significant trend towards increase in overall incidence during the 6-year period (chi(2) = 6.210, P = 0.013), and in age group 5-9 (chi(2) = 10.8, P = 0.001). Seasonality was demonstrated overall, in boys and girls (P < 0.001). CONCLUSION: The incidence of Type 1 diabetes in Kuwait is high compared with the neighbouring Arab countries, and it appears to be increasing as in many European populations.

Impact of glycemic control on serum lipoprotein (a) in Arab children with type 1 diabetes.

BACKGROUND: Lipoprotein (a) (Lp (a)) is an independent risk factor for coronary artery disease (CAD), a major cause of death in patients with type 1 diabetes mellitus. Both type 1 diabetes and CAD represent major problems in Kuwait. Data on the effect of metabolic control on Lp (a) in diabetic children are limited and this is particularly true for Arab children. The objectives of the present study were to analyze serum Lp (a) levels in patients with type 1 diabetes compared with non-diabetic children, taking into account the effect of glycemic control. METHODS: Circulating lipids, including Lp (a), were measured in serum samples from 60 prepubertal non-diabetic children and 58 prepubertal children with type 1 diabetes. Comparisons of Lp (a) concentrations were made between the non-diabetic and diabetic children with good to fair control (glycosylated hemoglobin (GHb) <11%) and a group of diabetic children with poor control (GHb > or = 11%). RESULTS: The mean serum Lp (a) level in all diabetic children was 187.62+160.43 mg/L, compared with 162.88+156.06 mg/L in the control group. The group of children with poor glycemic control had higher median Lp (a) levels (147.50 mg/L) than either the group of diabetic children with good to fair control (95 mg/L; P<0.028) or the group of non-diabetic children (125 mg/L; P<0.04). Moreover, 38.3% of poorly controlled diabetic children had elevated Lp (a) levels > or = 250 mg/L, compared with 12.5% of diabetic children with good to fair control and 16.7% of non-diabetic children (P<0.025 and P<0.039, respectively). No association was found between Lp (a), diabetes duration and insulin dose. CONCLUSIONS: In Arab children, highest Lp (a) levels are associated with poorest metabolic control. The prevalence of Lp (a) levels associated with cardiovascular risk is higher in poorly controlled diabetic children. Increased levels of Lp (a) may be another contributing factor to the high risk for CAD in diabetic patients.

High frequency of HLA-DQB1 non-Asp(57) alleles in Kuwaiti children with insulin-dependent diabetes mellitus.

The prevalence of polymorphic amino acids at position 57 of the HLA DQB1 in Kuwaiti children with insulin-dependent diabetes mellitus (IDDM) and nondiabetic controls has been determined using a polymerase chain reaction-sequence-specific primers (PCR-SSP) method. Using this approach, 34/55 (62%) IDDM children were found to be homozygous Ala/Ala and 19/55 (35%) were heterozygous with various combinations. Amongst the IDDM children with heterozygous genotype at codon 57 of HLA DQB1, 6/55 (11%) had Asp/Ala, 8/55 (15%) had Ala/Val, 4/55 (7%) had Ala/Ser and 1/55 had Asp/Val allelic combinations. When considered collectively, the nonaspartate (NA) alleles were represented in 87% of the IDDM cases and only 13% cases had Asp(57) allele in different heterozygous combinations, while none of the IDDM subjects had a homozygous Asp genotype. In nondiabetic controls, homozygous non-Asp (NA) alleles were represented in 44% subjects, 37% of the controls were heterozygous (NA/A) and 19% had a homozygous (A/A) genotype. These differences between the IDDM group and the control group were found to be statistically significant. Our data report one of the highest frequency of NA/NA residues at this locus compared with that from different world populations (Sardinians, Norwegians, US Caucasians, US Blacks and Chinese).

Implication of Granulocyte-Macrophage Colony Stimulating Factor (GM-CSF) and Interleukin-3 (IL-3) in Children with Acute Myeloid Leukaemia (AML).

Granulocyte-macrophage colony stimulating factor (GM-CSF) and Interleukin-3 (IL-3) are increasingly used to stimulate granulopoiesis in neutropenic patients but these are rarely used in the lights of knowledge of the endogenous CSF-levels. In this study we measured serum levels of GM-CSF and IL-3 at diagnosis and after remission in children with acute leukaemia, using an enzyme linked immuno-sorbent assay (ELISA) techniques in 14 patients with acute myeloid leukaemia (AML) and 27 patients with acute lymphoblastic leukaemia (ALL). Twelve healthy age-matched children were used as a reference group. AML patients showed a highly significant increase in serum levels of GM-CSF and IL-3 before induction of therapy (p < 0.0001) compared to the reference control group, with a highly significant decline of both GM-CSF and IL-3 (p < 0.0001) after successful remission. On the other hand, ALL patients showed no significant elevation of GM-CSF and IL-3 at diagnosis (p > 0.5), with no significant difference between preinduction and postinduction serum levels of either (p > 0.5). Since these cytokines are known to be fundamental for the growth of AML cells, we postulate that the pretreatment levels of both GM-CSF and IL-3 could play a role in the pathogenesis of AML.

Kenny-Caffey syndrome: an Arab variant?

We describe 2 unrelated Bedouin girls who met the criteria for the diagnosis of Kenny-Caffey syndrome. The girls had some unusual features--microcephaly and psychomotor retardation--that distinguish the Kenny-Caffey syndrome profile in Arab children from the classical Kenny-Caffey syndrome phenotype characterized by macrocephaly and normal intelligence. The 2 girls did not harbor the 22q11 microdeletion (the hallmark of the DiGeorge cluster of diseases) that we previously reported in another Bedouin family with the Kenny-Caffey syndrome (Sabry et al. J Med Genet 1998: 35(1): 31-36). This indicates considerable genetic heterogeneity for this syndrome. We also review previously reported 44 Arab/Bedouin patients with the same profile of hypoparathyroidism, short stature, seizures, mental retardation and microcephaly. Our results suggest that these patients represent an Arab variant of Kenny-Caffey syndrome with characteristic microcephaly and psychomotor retardation. We suggest that all patients with Kenny-Caffey syndrome should be investigated for the 22q11 microdeletion. Other possible genetic causes for the Kenny-Caffey syndrome or its Arab variant include chromosome 10p abnormalities.

Factors associated with obesity in Kuwaiti children.

The prevalence of adult obesity in Kuwait is among the highest in the Arab peninsula, and cardiovascular disease, for which obesity is a risk factor, is the leading cause of death. This study reports familial and environmental factors associated with childhood obesity; in addition to adverse effects of obesity on children's serum lipids, lipoproteins, apolipoproteins, insulin, and blood pressure profiles. The authors carried out a pair-matched case-control study including 460 obese (body mass index >90th percentile of the age/sex specific reference value of the National Center for Health Statistics), school children 6 to 13 years old matched by age and gender to 460 normal weight controls. We ascertained obese children in a cross-sectional survey of a representative sample of 2400 school children selected from 20 schools by multistage stratified random sampling. Biochemical variables and blood pressure were adversely affected in obese children. The conditional logistic regression analysis showed that family history of obesity, and diabetes mellitus, respiratory and bone diseases in child were significant associated factors with obesity after adjusting for social and behavioural factors. Physical activity and parental social class were not significant. We recommend early preventive measures with emphasis on families in which one or both parents are overweight.

Opportunistic intestinal protozoal infections in immunocompromised children.

Hundred immunocompromised children and 100 house contact controls were chosen. Patients included: 52 nephrotic syndrome children receiving corticosteroids for more than one month (age 5.28 +/- 2.32 years), 14 protein-calorie malnutrition (PCM) patients (8 cases of marasmus aged 6 +/- 2.27 months and 6 cases of marasmic kwashiorkor aged 1.39 +/- 0.88 years) and 34 lymphomas patients (22 cases of Hodgkin's disease and 12 cases of non-Hodgkin's lymphoma; age 4.5 +/- 3.54 years). Examination of concentrated stool was done using iodine stain of fresh mounts and modified Ziehl-Neelsen (cold acid-fast) to fixed smears. T-cell subsets were counted after staining with mouse monoclonal antibodies against CD4 and CD8 labeled with fluorescein. Both nephrotic syndrome and lymphomas groups showed affection of cellular immunity in the form of significant decrease in T-helper and H/S ratio and significant increase in suppressor T-cell subsets. Giardia lamblia, Entamoeba histolytica, Cryptosporidium parvum and Blastocystis hominis were the most frequent in patients group and were significantly more prevalent among patients than controls. No significant difference in the prevalence of Entamoeba coli and Chylomastix mesnili between the two groups. C. parvum infection were strictly confined to groups with T-cell subsets abnormalities i.e. nephrotic syndrome and lymphomas groups.

Prevalence of human leukocyte antigen DQA1 and DQB1 alleles in Kuwaiti Arab children with type 1 diabetes mellitus.

The prevalence of human leukocyte antigen (HLA) DQB1 and DQA1 alleles has been determined in 78 Kuwaiti Arab children with insulin-dependent diabetes mellitus (IDDM) and in 57 normal healthy controls with similar ethnic background. The typing of HLA-DQ alleles was carried out using an allele-specific DNA-based polymerase chain reaction (PCR) SSP method. DR typing was also performed in 212 control subjects using PCR-SSP (sequence specific primer) method. A significantly higher frequency of DQB1*0201 allele was found in IDDM cases compared to the controls (p<0.001). There was no significant difference in the prevalence of DQB1 alleles *0302, *0501, and *0602 between IDDM cases and the controls. In contrast, DQB1 alleles *0301, *0402, *0502, *0602, and *0603 were represented at a somewhat higher frequency in controls compared to the IDDM cohort. The frequency of DQA1 allele *0301, which encode for an Arg at codon 52, was significantly higher in the IDDM patients compared to the controls (p<0.001). The frequency of DQA1 allele *0302 was also higher in IDDM cases than controls (p = 0.034) but the difference was less pronounced than DQA1*0301. Amongst the Arg52 alleles, no significant difference was detected in the frequency of *0401 between IDDM cases and the controls and the allele *0501 was detected only in controls. For non-Arg52 alleles *0103, *0104, and *0201, the differences in the two groups were not significant, with the exception of allele *0104 (p = 0.024). DR3 was the most common type in the Kuwaiti general population (28%) and DRB1*0301 was detected in 41% of the individuals with DR3 specificity. Analysis of HLA-DQBI/DQA1 haplotypes from IDDM cases and controls revealed a significantly high frequency of haplotype DQA1*0301/DQB1*0201 between Kuwaiti IDDM cases (49/78, 63%) and the controls (8/57, 14%).

Apolipoproteins A-I and B in Kuwaiti children.

To assess the relation of apolipoproteins (Apos) A-I and B (the carrier proteins for high and low density lipoprotein cholesterol, respectively) with the degree of obesity, body fat distribution, serum lipids, glucose and insulin levels, a case-control study was carried out and included 460 Kuwaiti obese children, 6-13 years old, matched by age and sex to 460 normal-weight controls. Obese children were ascertained in a representative cross-sectional study of 2,400 school children. The Apo A-I levels were not different between obese and non-obese boys, while they were significantly lower in obese girls (p < 0.01). The Apo B mean concentrations were significantly higher in obese boys and girls (p < 0.001), while the Apo A-I:B ratio was significantly lower in obese children (p < 0.001). Apo A-I levels were positively correlated with total cholesterol, high- and low-density lipoprotein cholesterol, but were not correlated with very low-density lipoprotein cholesterol, triglycerides, insulin, glucose or insulin:glucose ratio. Apo B levels were negatively correlated with high-density lipoprotein cholesterol and positively correlated with insulin and insulin:glucose ratio (p < 0.01) in obese children. The study documented an adverse Apo profile in obese Kuwaiti children. Since Apo changes are correctable through management of obesity, their identification in childhood offers prospects for prevention of early onset atherogenesis in adulthood.

Anti-schistosomal IgE and its relation to gastrointestinal allergy in breast-fed infants of Schistosoma mansoni infected mothers.

To study the relationship between presence of gastrointestinal allergic manifestations in breast-fed infants and presence of IgE against Schistosoma mansoni antigens, sixty breast-fed infants of S. mansoni infected mothers were selected. Of them, thirty infants were suffering from manifestations of gastrointestinal allergy (patients) and the other thirty were not suffering from such manifestations (controls). Levels of IgE against S. mansoni adult worm antigen (AWA), soluble egg antigen (SEA) and cercarial antigen (CA) were determined, by ELISA, in sera of these infants. There was significant association between presence of allergic manifestations and presence of IgE against AWA (P = 0.018), SEA (P < 0.001) and CA (P = 0.002). Also, concentration of IgE against AWA was significantly higher in patients group than the control group (P = 0.024). IgE against AWA showed significant negative correlation with haemoglobin concentration (P = 0.009) and serum albumin level (P = 021) and significant positive correlation with absolute eosinophilic count (P = 0.005). Also, IgE against CA showed significant negative correlation with haemoglobin concentration (p = 0.047) and serum albumin level (0 = 0.036). It was concluded that gastrointestinal allergy in breast-fed infants of S. mansoni infected mothers may be due to hypersensitivity of Schistosoma mansoni antigens present in mothers' milk. Schistosoma mansoni should be investigated and treated in mothers from endemic localities when their breast-fed infants are suffering from manifestations suggestive of gastrointestinal allergy.

Association of fasting insulin with serum lipids and blood pressure in Kuwaiti children.

To examine the association of hyperinsulinemia with the atherogenic risk profile in children, we studied the relationships of the fasting plasma insulin level with indices of obesity (body mass index [BMI] and sum of triceps and subscapular skinfold thickness [SFT]), body fat distribution (waist to hip ratio [WHR]), serum lipid, lipoprotein, and apolipoprotein levels, and blood pressure in a case-control study of 460 Kuwaiti prepubertal obese children aged 6 to 13 years matched by age and sex to 460 prepubertal non-obese controls. Obese children were ascertained in a representative cross-sectional study of 2,400 school children. Fasting insulin levels were positively correlated (P < .001) with serum triglyceride (TG) and very-low-density lipoprotein (VLDL) cholesterol levels and negatively correlated with high-density lipoprotein (HDL) cholesterol levels. No significant associations were observed between insulin and total cholesterol (TC), cholesterol, low-density lipoprotein (LDL) or apolipoprotein A-I (apo A-I). Stronger associations of insulin levels with lipoprotein fractions were observed in obese versus non-obese controls. Obese children had a higher concentration of apo B and a lower apo A-I:B ratio (P < .001). Insulin and the insulin to glucose ratio increased with age in obese children, whereas there were slight changes in non-obese children. TG and HDL cholesterol levels and systolic blood pressure (SBP) were significantly different across insulin quartiles in boys and girls. We conclude that the fasting plasma insulin level may be used as a marker for the development of obesity-associated metabolic disorders and elevated blood pressure in children.

Kawasaki disease: clustering in infants and pre-school children in Kuwait.

We report five children who presented within a 2-month period and who all fulfilled at least four of the five criteria essential for the diagnosis of Kawasaki disease. They were three girls and two boys aged between 5 months and 3 years. Two of them had atypical presentations; one mimicked infectious mononucleosis and the other had severe abdominal pain and was later found to have hydrops of the gall bladder. Although treatment was started within the 1st 10 days of the illness, echocardiographic changes were found in three cases: one had myocarditis and the other two showed in the coronary arteries. The occurrence of five cases in such as short period of time is similar to the clusterings of Kawasaki disease reported in Japan and the USA, and strongly suggests the presence of a causative infectious agent.

Incidence and severity of ketoacidosis in childhood-onset diabetes in Kuwait. Kuwait Diabetes Study Group.

In 1992, the diabetes registry was started in Kuwait, as part of DiaMond, a WHO multinational collaborative project on the incidence of childhood-onset diabetes. Children (243) aged below 15 years, were identified between 1 January 1992 and 31 December 1995. Children (203) were Kuwaiti and 40 were non-Kuwaiti children but resident of Kuwait. For the years 1992, 1993, the annual incidence of childhood onset diabetes for Kuwaiti children was 15.4 per 100,000 (95% confidence interval 12.9-19), and the degree of ascertainment was 92%. Polyuria, polydypsia, weight loss and nocturia were the most frequently reported symptoms; four children were in coma and one in shock at presentation. Nearly half of the children (49%) presented ketoacidosis (venous pH < 7.3 and/or plasma bicarbonate level < 18 mmol/l). and in 53 children (23.5%) it was severe (venous pH < 7.1 and/or plasma bicarbonate level < 10 mmol/l). In 62 children (25.5%) it was mild to moderate (venous pH 7.1-7.3 and/or plasma bicarbonate level 10.1-18 mmol/l). The incidence of severe ketoacidosis was similar in all age groups and sexes. All children recovered completely without major complications and no deaths were recorded. We conclude that diabetic ketoacidosis is a common presentation at the onset of diabetes in childhood in Kuwait and attests to the lack of awareness of general practitioners and parents to the symptoms and signs of diabetes in childhood.
