Abstract
It is well known that buildings have a sizeable energy and environmental footprint. In particular, in environments like university campuses, the occupants as well as occupancy in shared spaces varies over time. Systems for cooling in such environments that are centrally controlled are typically threshold driven and do not account for occupant feedback and thus are often relying on a reactive approach (fix after identifying problems). Therefore, having a fixed thermal operating set point may not be optimal in such cases-both from an occupant comfort and well-being as well as an energy efficiency perspective. To address this issue, a study was conducted which involved development and deployment of an experimental Internet of Things (IoT) prototype system and an Android application that facilitated people engagement on a university campus located in the UAE which typically exhibits hot climatic conditions. This paper showcases data driven insights obtained from this study, and in particular, how to achieve a balance between the conflicting goals of improving occupant comfort and energy efficiency. Findings from this study underscore the need for regular reassessments and adaptation. The proposed solution is low cost and easy to deploy and has the potential to reap significant savings through a reduction in energy consumption with estimates indicating around 50-100 kWh/day of savings per building and the resulting environmental impact. These findings would appeal to stakeholders who are keen to improve energy efficiency and reduce their operating expenses and environmental footprint in such climatic conditions. Furthermore, collective action from a large number of entities could result in significant impact through this cumulative effect.

Abstract
Background The pathogenesis of inflammatory bowel disease (IBD) which includes Crohn’s disease (CD) and ulcerative colitis (UC), is believed to involve activation of the intestinal immune system in response to the gut microbiome among genetically susceptible hosts. IBD has been historically regarded as a disease of developed nations, though in the past two decades there has been a reported shift in the epidemiological pattern of disease. High-income nations with known high prevalence of disease are seeing a stabilization of incident cases, while a rapid rise of incident IBD is being observed in developing nations. This suggests that environmental exposures may play a role in mediating the risk of developing IBD. The potential environmental determinants of IBD across various regions is vast, though medications have been increasingly recognized as one broad category of risk factors. Purpose Several medications have been considered to contribute to the etiology of IBD. This study assessed the association between medication use and risk of developing IBD using the Prospective Urban Rural Epidemiology (PURE) cohort. Method This was a prospective cohort study of 133,137 individuals between the ages of 20-80 from 24 countries. Country-specific validated questionnaires documented baseline and follow-up medication use. Participants were followed prospectively at least every 3 years. The main outcome was development of IBD, including CD and UC. Short-term (baseline but not follow-up use) and long-term use (baseline and subsequent follow-up use) was evaluated. Results are presented as adjusted odds ratios (aOR) with 95% confidence intervals (CI). Result(s) During the median follow-up of 11.0 years [interquartile range (IQR) 9.2-12.2], we recorded 571 incident cases of IBD (143 CD and 428 UC). Higher risk of incident IBD was associated with baseline antibiotic use [aOR: 2.81 (95% CI: 1.67-4.73), p=0.0001] and hormonal medication use [aOR: 4.43 (95% CI: 1.78-11.01), p=0.001]. Among females, previous or current oral contraceptive use was also associated with IBD development [aOR: 2.17 (95% CI: 1.70-2.77), p=5.02E-10]. NSAID users were also observed to have increased risk of IBD [aOR: 1.80 (95% CI: 1.23-2.64), p=0.002], which was driven by long-term users [aOR: 5.58 (95% CI: 2.26-13.80), p<0.001]. All significant results were consistent in direction for CD and UC with low heterogeneity. Conclusion(s) Antibiotics, hormonal medications, oral contraceptives, and long-term NSAID use were associated with increased odds of incident IBD after adjustment for covariates.

Abstract
INTRODUCTION Acute pneumonia is a leading infectious cause of death among children under 5 years globally and in Nigeria. Despite various existing strategies and interventions, pneumonia mortality remains unacceptably high. Novel interventions like improving vitamin D status may be needed as optimal vitamin D status may facilitate the ability of immune cells to fight against infections like pneumonia. We investigated the relationship between serum vitamin D [25(OH)D] levels and acute pneumonia in children younger than 5 years in Nigeria. SUBJECTS AND METHODS This cross-sectional study involved 135 children with pneumonia and 135 apparently healthy controls. Acute pneumonia was diagnosed using the revised World Health Organization criteria (2012) and chest radiological signs. Serum 25(OH)D concentrations were determined using a vitamin D ELISA kit. The mean serum 25(OH)D levels in both groups were compared and also determined odds ratio (OR) of pneumonia. RESULTS The mean serum 25(OH)D level of children with pneumonia (52.14 ± 21.87 nmol/l) was significantly lower than that of controls (60.91 ± 32.65 nmol/l), p = 0.010. The proportion of children with low serum vitamin D levels (≤75.0 nmol/l) was significantly higher in the pneumonia group (n = 123, 91.1%) than the control group (n = 97, 71.9%), p < 0.001. After adjusting for confounders, serum 25(OH)D levels of greater than 75 nmol/l was associated with decreased odds of acute pneumonia (adjusted OR = 0.33, p = 0.007). CONCLUSION A low vitamin D level was associated with increased risk of acute pneumonia. Lay summary. INTRODUCTION Chest infection (pneumonia) is a leading cause of death in children younger than 5 years of age globally and also in Nigeria. Pneumonia death is still very high despite all the existing efforts at reducing it. New methods may still be needed to drastically reduce this problem. One of these new methods may include improving the vitamin D status of an individual because optimal vitamin D levels may help the body to fight against infections like pneumonia. We investigated the relationship between blood levels of vitamin D and pneumonia in children younger than 5 years. SUBJECTS AND METHODS Vitamin D levels of 135 children with pneumonia were measured and compared with vitamin D levels of another 135 healthy children without pneumonia. We diagnosed pneumonia by using both revised World Health Organization criteria (2012) and chest X-rays signs. Blood levels of vitamin D were measured using a vitamin D ELISA kit. RESULTS The average blood vitamin D level of children with pneumonia (52.14 ± 21.87 nmol/l) was low compared with that of children without pneumonia (60.91 ± 32.65 nmol/l), p = 0.010. The number of children with low blood vitamin D levels (≤75.0 nmol/l) was more in the pneumonia group (n = 123, 91.1%) than in children without pneumonia (n = 97, 71.9%), p < 0.001. After adjusting for other potential risk factors, blood level of vitamin D >75 nmol/l was associated with lower risk of having pneumonia, (adjusted OR = 0.33, p = 0.007). CONCLUSION A low vitamin D level was associated with increased risk of acute pneumonia.

Abstract
BACKGROUND Stroke has been a global burden, with increasing morbidity and mortality. Serum cardiac troponin t (cTnT) and creatine kinase (CK-MB) fraction are reported to be elevated in patients admitted with acute ischaemic stroke and high level of these biomarkers indicated more severe stroke and neurologic deficit in some of the patients. OBJECTIVE To evaluate the serum levels cardiac troponin t (cTnT) and creatine kinase MB fraction (CK-MB) in patients with acute ischaemic stroke and relate the analytes to severity of stroke. METHOD Patients with clinical diagnosis of ischaemic stroke diagnosed, confirmed by brain Computerized Tomography scan and equal number of apparently healthy age and sex-matched were recruited. Serum cardiac troponin t (cTnT) and creatine kinase MB fraction (CK-MB) were analysed using ELISA method and Stroke severity was determined using National Institute of Health Stroke Score (NIHSS). RESULTS Mean serum cardiac troponin t (cTnT) and creatine kinase MB fraction (CK-MB) in stroke patients were found to be higher than age sex matched control (p<0.05). NIHS Score of 12.2 ± 5.43 and 9.78 ± 3.97 were observed in Patients with elevated and normal cTnT respectively (p=0.009) while NIHS Score were similar in patients with elevated and normal CK-MB (p = 0.772). CONCLUSION The mean values of serum cTnT and CK-MB were higher in acute ischaemic stroke patients compared to controls. Serum cardiac Troponin t level may be a significant biomarker of the severity of stroke.

Abstract
BACKGROUND AND OBJECTIVE Multiorgan failure including liver dysfunction is a common finding in sickle cell anemia (SCA) patients, the cause of which is multifactorial with advancing age said to be a major determinant. There is a paucity of data on liver function among SCA patients in relation to age in northern Nigerian hospitals, including Ahmadu Bello University Teaching Hospital (ABUTH), Zaria. This study was to assess the biochemical liver function tests (LFTs) as they relate to age among SCA patients in steady state, with a view to improving the overall monitoring of these patients. SUBJECTS AND METHODS This study was carried out in ABUTH, Zaria, Northern Nigeria. LFTs were carried out in 100 SCA and 100 apparently healthy participants (controls). The SCA group was made up of fifty adults and fifty children diagnosed of SCA, whereas the control group was made up of fifty adults and fifty children who were apparently healthy and had hemoglobin AA. Paired two-tailed Student's t-test for matched samples and Pearson's linear correlation statistical methods were employed for the data analysis using Microsoft Office Excel 2007. A P ≤ 0.05 was considered as statistically significant. RESULTS The serum concentrations of total bilirubin (TB), alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), and AST/ALT ratio were significantly higher in SCA patients compared to the controls (P = 0.001, P = 0.001, P = 0.05, P = 0.05 and P = 0.001, respectively). Serum total protein (TP) and ALB were significantly lower (P = 0.01 and P < 0.05, respectively) in SCA patients compared with the controls. The levels of TB, ALT, AST, ALP, and AST/ALT were significantly lower in SCA adults compared to SCA children, whereas TP and ALB were higher in SCA adults compared to the SCA children. There were significant negative correlations between age and each of TB, ALT, AST, ALP, and AST/ALT, and significant positive correlations between age and each of TP and ALB in SCA patients. CONCLUSION There are mild LFTs derangements in SCA patients even in steady state with the extent of the abnormalities decreasing with advancing age of the patients.

Abstract
The present study investigated the anti-hyperglycaemic effect of rutin on blood glucose, oxidative stressbiomarkers and lipid peroxidation in alloxan induced hyperglycaemic wistar rats. Diabetes was induced in rats by anintraperitoneal (i.p) injection of alloxan monohydrate 150 mg/kg body weight. Twenty five wistar rats were divided asfollows; Group1 served as diabetic control received distilled water 2 mg/kg, Group served as positive control received 2mg/kg glibenclamide, 3, 4 and 5 received rutin at 50, 100 and 200 mg/kg body weight for 28 days respectively. At the end of the treatment, rats were sacrificed and the blood and serum were used for the analysis of blood glucose and oxidativestress biomarkers respectively. The determinations of blood glucose levels were carried out at intervals of 7, 14, 21 and 28days respectively Serum oxidative stress biomarkers lipid peroxidation, were done on the 28 days. Administrations of rutinat the three different doses 50,100 and 200 mg/kg to diabetic rats significantly (p<0.05) decreased the blood glucose levelsas compared to diabetic control. The dose of 200 mg/kg exhibited a maximum glucose lowering effect with blood glucoseof 102.8± 0.06 as compared to diabetic control 346.2±0.16. Furthermore, in relation to the oxidative stress biomarkers therewas a significant (p<0.05) increased in the levels of gluthathione peroxidase, superoxide dismutase and catalase as comparedto control. However, there was also a significant decreased in the malondialdehyde levels as compared to control. It may beconcluded that oral administration of Rutin for 28 days decreases blood glucose levels and prevented oxidative stress andantioxidant status in hyperglycaemic rats.

Abstract
Background/Objectives: Psychosocial stress has been proposed to contribute to obesity, particularly abdominal, or central obesity, through chronic activation of the neuroendocrine systems. However, these putative relationships are complex and dependent on country and cultural context. We investigated the association between psychosocial factors and general and abdominal obesity in the Prospective Urban Rural Epidemiologic study. Subjects/Methods: This observational, cross-sectional study enrolled 151 966 individuals aged 35–70 years from 628 urban and rural communities in 17 high-, middle- and low-income countries. Data were collected for 125 290 individuals regarding education, anthropometrics, hypertension/diabetes, tobacco/alcohol use, diet and psychosocial factors (self-perceived stress and depression). Results: After standardization for age, sex, country income and urban/rural location, the proportion with obesity (body mass index ⩾30 kg m−2) increased from 15.7% in 40 831 individuals with no stress to 20.5% in 7720 individuals with permanent stress, with corresponding proportions for ethnicity- and sex-specific central obesity of 48.6% and 53.5%, respectively (P<0.0001 for both). Associations between stress and hypertension/diabetes tended to be inverse. Estimating the total effect of permanent stress with age, sex, physical activity, education and region as confounders, no relationship between stress and obesity persisted (adjusted prevalence ratio (PR) for obesity 1.04 (95% confidence interval: 0.99–1.10)). There was no relationship between ethnicity- and sex-specific central obesity (adjusted PR 1.00 (0.97–1.02)). Stratification by region yielded inconsistent associations. Depression was weakly but independently linked to obesity (PR 1.08 (1.04–1.12)), and very marginally to abdominal obesity (PR 1.01 (1.00–1.03)). Conclusions: Although individuals with permanent stress tended to be slightly more obese, there was no overall independent effect and no evidence that abdominal obesity or its consequences (hypertension, diabetes) increased with higher levels of stress or depression. This study does not support a causal link between psychosocial factors and abdominal obesity.

Abstract
Forty-six bottled water samples representing 16 brands from Dhaka, Bangladesh were tested for the numbers of total coliforms, fecal indicator bacteria (i.e., thermotolerant Escherichia coli and Enterococcus spp.) and potential bacterial pathogens (i.e., Aeromonas hydrophila, Pseudomonas aeruginosa, Salmonella spp., and Shigella spp.). Among the 16 brands tested, 14 (86%), ten (63%) and seven (44%) were positive for total coliforms, E. coil and Enterococcus spp., respectively. Additionally, a further nine (56%), eight (50%), six (37%), and four (25%) brands were PCR positive for A. hydrophila lip, P. aeruginosa ETA, Salmonella spp. invA, and Shigella spp. ipaH genes, respectively. The numbers of bacterial pathogens in bottled water samples ranged from 28 ± 12 to 600 ± 45 (A. hydrophila lip gene), 180 ± 40 to 900 ± 200 (Salmonella spp. invA gene), 180 ± 40 to 1,300 ± 400 (P. aeruginosa ETA gene) genomic units per L of water. Shigella spp. ipaH gene was not quantifiable. Discrepancies were observed in terms of the occurrence of fecal indicators and bacterial pathogens. No correlations were observed between fecal indicators numbers and presence/absence of A. hydrophila lip (p = 0.245), Salmonella spp. invA (p = 0.433), Shigella spp. ipaH gene (p = 0.078), and P. aeruginosa ETA (p = 0.059) genes. Our results suggest that microbiological quality of bottled waters sold in Dhaka, Bangladesh is highly variable. To protect public health, stringent quality control is recommended for the bottled water industry in Bangladesh.

Abstract
BACKGROUND AND OBJECTIVES HPA-1a antibodies account for 70-80% of cases of fetal-neonatal alloimmune thrombocytopenia (FNAIT) in Caucasians. However, numerous workshops have demonstrated variability in their detection. We recently showed that exposure of αIIbβ3 to ethylene diamine tetraacetic acid (EDTA) affected binding of many anti-αIIbβ3 monoclonal, and HPA-1a allo-, antibodies; this adversely affected sensitivity of the monoclonal antibody-specific immobilization of platelet antigens (MAIPA) assay and indirect platelet immunofluorescence test (PIFT). This study presents results from an international workshop studying the impact of cation chelation on HPA-1a antibody detection in routine diagnostic laboratories. MATERIALS AND METHODS Serum and EDTA-anticoagulated plasma samples containing anti-HPA-1a were distributed to 39 laboratories. Participants were asked to detect and identify any HPA antibodies present. RESULTS 2/39 (5.1%) participants were able to detect and identify anti-HPA-1a in the serum, but not in the plasma sample. EDTA plasma reduced MAIPA assay sensitivity by ≥ 20% in 17/24 (70.8%) laboratories and by ≥ 50% in 9/24 (37.5%) when using HPA-1a1a platelets (mean: 27.7%, range 0-85.1%); when using HPA-1a1b platelets 3/4 (75%), participants reported ≥ 50% loss of sensitivity (mean 65.6%, range 0-96.6%). A small but significant increase in optical densities was observed in antigen capture ELISA assays when using plasma (mean difference: 0.081, P < 0.01). Insufficient PIFT data were returned to draw firm conclusions. CONCLUSION Use of EDTA plasma significantly affects the sensitivity of the MAIPA assay and can affect detection of even potent, FNAIT-causing examples of anti-HPA-1a. These data highlight the importance of use of αIIbβ3 in an appropriate conformation for the sensitive detection of anti-HPA-1a.

Abstract
OBJECTIVES During infancy and early childhood, the spleen commonly enlarges in patients with sickle cell anemia (SCA), and it thereafter undergoes progressive atrophy due to repeated episodes of vaso-occlusion and infarction, leading to autosplenectomy in adult life. However, this may not always be the case as some studies have reported splenomegaly persisting into adult life. This study aims to determine and review the prevalence of autosplenectomy by abdominal ultrasonography in sickle cell anemic patients in Zaria, Nigeria. METHODS An ex-post-facto cross study of 74 subjects was carried out between May to July in 2010. Hematological parameters were determined by an analyzer while B mode Ultrasonography was used to determine the craniocaudal length of the spleen, if visualized. RESULTS The mean age of the sickle cell subjects was 23.2 ±5.3 years, while that of the controls was 22.7±12.4 years. Of the 74 sickle cell subjects, 55.4% were females; while of the 20 controls, 50% were females. Forty one subjects (55.4%) had autosplenectomy and a significant difference existed in the mean splenic size compared with the control (p<0.0001). Only 3 (4.05%) subjects had splenomegaly, while 23 (31%) had a shrunken spleen. CONCLUSION Anatomical autosplenectomy is not an uncommon finding in SCA patients. This may be related to inadequate clinical care due to the lack of good health education, ignorance, poverty, and poor standard of care, as well as the lack of newer therapeutic agents.

Abstract
OBJECTIVE Osteopontin (OPN) is overexpressed in tumors and serum of ovarian cancer patients and may serve as a biomarker. To evaluate the utility of serum osteopontin in monitoring disease status, we evaluated 234 serum samples from post-oophorectomy patients with ovarian cancer and 38 samples from healthy controls. METHODS Serum samples were collected from 203 women with recurrent ovarian cancer and 31 newly diagnosed women participating in an experimental chemotherapeutic clinical trial. Controls included 11 young healthy women and 27 peri- or postmenopausal women without ovarian cancer. Samples were assayed for osteopontin using an enzyme-linked immunosorbent assay (ELISA) kit. Statistical analyses for group comparisons of biomarker distribution used the nonparametric Wilcoxon's rank sum test for two-group comparisons and the Kruskal-Wallis test for three-group comparisons. RESULTS Osteopontin values ranged from 25 to 1463 ng/ml for patients and 25 to 617 ng/ml for controls. Mean patient levels were lower than mean control levels (74 ng/ml vs. 147 ng/ml, respectively, P = 0.0006). Serum osteopontin levels correlated with recurrent disease versus remission (68 ng/ml vs. 34 ng/ml, P = 0.0034), presence of ascites versus absence (71 ng/ml vs. 53 ng/ml, P = 0.0002), and bulky disease vs. nonbulky disease (75 ng/ml vs. 38 ng/ml, P = 0.0005). CA-125 values yielded the same trends with greater statistical difference. CONCLUSIONS These results demonstrate that serum osteopontin concentrations in post-oophorectomy patients with recurrent ovarian cancer are not greater than in healthy controls. Nevertheless, within this heterogeneous patient population, the values do correlate with bulk of disease. The potential utility of this assay in monitoring women with CA-125 negative disease is worthy of exploration.

Abstract
Traditional remedies have been a source of important antimalarial drugs and continue to provide novel and effective treatments, both where pharmaceuticals are not available and where the disease is increasingly resistant to commonly prescribed drugs. The Kenyah of the Apo Kayan, a remote forested plateau in Indonesian Borneo, use 17 malaria remedies derived from natural sources. A quantitative analysis of the relationship between a 'local importance value' index for each malaria remedy (IVmal) and inhibition of cultured Plasmodium falciparum by ethanolic extracts supports the hypothesis that the degree of local consensus about a given remedy is a good indicator of its potential biological efficacy. Our results confirm the rational selection and use of traditional remedies for malaria by the Kenyah. We have identified target species for further research directed toward safe and effective treatments for malaria.

Abstract
A retrospective study had been done at the outpatient clinic sub division of Pediatric Gastroenterology, Dr. Pirngcdi Hospital Medan, comprising patients from 1 January 1985-31 December 1987. There were 874 patients. Three hundred seventy eight (43.25%) patients consisting of 210 (55.56%) males and 168 (44.44%) females had intestinal parasitic infestations. The youngest patient was 5 months and the oldest was 14 years and 3 months. Ascaris lumbricoides was found in 215 patients (24.60%) while Trichuris trichiura, hookworm, Oxyuris vermicularis, Hymenolepis nana, and Taenia were in 152 (17.39%), 13 (1.49%), 4 (0.46%), 15 (1.72%) and 4 (0.46%) cases respectively. Entamoeba histolytica was found in 121 (13.84%) and Giardia lamblia in 16 (1.83%) patients. The highest age specific attack rate was found in the age group of 5-10 years (65.67%). Ascaris lumbricoides was most frequently found namely in 100 children (26.46%), followed by Entameba histolytica in 73 (19.31%) and mixed infestation of Ascaris lumbricoides and Trichuris trichiura in 68 (17.99%) patients. One hundred seventy three (66.28%) under five patients with intestinal parasitic infestation had malnutrition while of the 433 under fives without intestinal parasitic infestation only 201 (46.42%) suffered from malnutrition (P less than 0.001).
