Gas chromatography/mass spectrometry analysis and uv absorptivity of bio-oils extracted from some locally grown plant seeds in nothern Nigeria.

Oils play vital roles in various ramifications including health, and food industries. Oils which are components of plant seeds can be extracted using various extraction techniques. This research is an exposition into the chemistry of oils with possible repositioning for purposeful use in the cosmetic, pharmaceutical, and food industries especially as sunscreen. In this work, oils were extracted from nine different seeds and subjected to gas chromatography coupled to mass spectrometry, and Ultraviolet analysis. The extraction method adopted in this work shows that 5 out of the 9 seeds have a relatively high percentage yield ranging from 20.9 to 36.8 % which indicates their potential for use in commercial quantity. The GC- MS analysis shows that (Z, Z)- 9, 12-Octadecadienoic acid is the most abundant components of all the oil samples. n-Hexadecanoic acid and cis-Vaccenic acid are the major constituents of Swietenia macrophylla (mahogany) seed oil. The lead components in the oil samples are usually responsible for their physico-chemical and Ultraviolet interactivities. All the samples were found to have adequate absorbance for Ultraviolet radiation ranging from Ultraviolet C to Ultraviolet A region. Citrullus lanatus, Hyptis spicigera, and Swietenia macrophylla (mahogany) have the highest absorbance ranges of 1.394-1.718, 1.449 to 1.70,2 and 1.402 to 1.711 respectively at Ultraviolet A region. The finding shows that all the samples have the ability to protect the skin from Ultraviolet radiation when expose to the sun, whereas only Citrullus lanatus, Hyptis spicigera and Swietenia macrophylla (mahogany) have the potentials for use as sunscreen with high sun protection factor. Further studies on the antimicrobial activities, cosmeceutical and nutraceutical potentials of the various components of these samples are encouraged.

Short-term dynamics and long-term relationship between natural gas consumption and economic growth in Nigeria: an ARDL approach with breaks.

This paper investigates the short-term dynamics as well as the long-term relationship between natural gas consumption and economic growth in Nigeria, taking breaks into account. The techniques employed include Shahbaz-Omay-Roubaud unit root test with sharp and smooth breaks and autoregressive distributed lag (ARDL) model with breaks. The results revealed that natural gas consumption is positively related to growth both in the short-term and long-term but only significant in the latter. However, there is evidence of bidirectional causality in the long-term and unidirectional causality in the short-term, from growth to natural gas consumption. The implication of the findings is that natural gas is a contributing factor to the growth of the Nigerian economy, and any energy policy aimed at increasing the consumption of natural gas could lead to the increase in economic growth and that Nigerian authorities could adopt energy conservation policies in the short-term so as to take the issue of global warming into consideration. Therefore, the paper recommends stepping up efforts to increase natural gas consumption by building more gas storage facilities, pipeline installations, exploring alternative energy sources, raising awareness/enlightenment about the uses of natural gas, suitability in its use, economic and environmental benefits of its use, ensuring its affordable availability, and beeping up security against pipelines vandalization. Moreover, in the short-term, the country could enact energy conservation policies to combat global warming.

Childhood lead poisoning in Gaza Strip, the Palestinian Authority.

PURPOSE: To assess lead poisoning among a pediatric population in Gaza Strip, the Palestinian Authority. METHODS: A total of 1705 questionnaires and blood samples were collected from children aged 2-6 years, by the finger stick capillary procedure, for the assessment of blood lead level (BLL), using the LeadCare kits. The samples were collected from children living close to lead processing units (hotspots) and far 100-500 m away (general population). Management of elevated BLL was achieved by gavage of chelating agent d-penicillamine at a dose of 30 mg kg-1 body weight/day for two weeks for children having BLL above 20 µg/dl. Data were statistically analyzed using SPSS computer program version 22. RESULTS: Distribution of children in Gaza Strip by sampling process illustrated those 326 children (19.1%) living in lead processing units (hot spots) and 1379 children (80.9%) from location far away 100-500 m from host spot (general population). The mean BLL was 10.4 µg/dl. A total of 440 children (25.8%) were found to be having BLL ≥ 10 µg/dl while 1265 children (74.2%) have BLL < 10 µg/dl. BLL < 10 µg/dl was taken as a cut point due to CDC standards. The prevalence of BLL in hotspot areas in children who were exposed to lead and have BLL ≥ 10 µg/dl was 95.7% while in general population it was 9.3%. The difference between the study population was statistically significant (p < 0.01). Statistical significant differences between the study populations were found among several independent variables of risk factors such as household location and exposure sources, and occupational exposure. Gavage of d-penicillamine significantly reduced BLL to the acceptable level (BLL < 10 µg/dl). CONCLUSIONS: Childhood lead poisoning accounts for a substantial burden in Gaza Strip. Hotspots of lead-related industries are the high risk areas that contributing to high BLLs in children. d-Penicillamine was effective in the treatment of lead poisoning among children. Health education and treatment campaigns should be designed to minimize or prevent childhood lead poisoning in Gaza Strip.

Cost of Illness of Diabetic Foot Ulcer in a Resource Limited Setting: A Study from Northwestern Nigeria.

INTRODUCTION: Diabetic foot ulcer is a major complication of diabetes with a high economic cost of managing. Data from resource limited setting will bring to light how patients in these localities suffer financially in addition to poverty and lack of health insurance. This study estimated cost of illness among patients with diabetic foot ulcer in northwestern Nigeria. METHODS: It was a hospital based cross-sectional study. Questionnaire was used to take the bio data and medical history. Direct medical, direct non-medical and indirect cost were estimated. RESULT: Majority of the patients were males with the mean age of 59.3 ± 15.1 yrs. About 60% of the patients earn less than $100 monthly. The total cost of illness of diabetic foot ulcer was estimated at $140,735.56 (median = $1381.55[IQR 1002.42-]). Direct cost of illness was $107,797.06 (median = $1023.27[IQR 773.93-1568]), while the indirect cost was $32,938.49 (median = $209.90[IQR 128.74-357.08]). Out of pocket payment accounted for 90% of the payment. CONCLUSION: The cost of diabetic foot ulcer is very exorbitant and the patients affected are mostly poor, unemployed and the breadwinners of their families.

Childhood lead exposure in the palestinian authority, Israel, and Jordan: results from the Middle Eastern regional cooperation project, 1996-2000.

In the Middle East, the major sources of lead exposure have been leaded gasoline, lead-contaminated flour from traditional stone mills, focal exposures from small battery plants and smelters, and kohl (blue color) in cosmetics. In 1998-2000, we measured blood lead (PbB) levels in children 2-6 years of age in Israel, Jordan, and the Palestinian Authority (n = 1478), using a fingerstick method. Mean (peak; percentage > 10 microg/dL) PbB levels in Israel (n = 317) , the West Bank (n = 344), Jordan (n = 382) , and Gaza (n = 435) were 3.2 microg/dL (18.2 ; 2.2%) , 4.2 microg/dL (25.7; 5.2%), 3.2 microg/dL (39.3; < 1%) , and 8.6 microg/dL (> 80.0; 17.2%), respectively. High levels in Gaza were all among children living near a battery factory. The findings, taken together with data on time trends in lead emissions and in PbB in children in previous years, indicate the benefits from phasing out of leaded gasoline but state the case for further reductions and investigation of hot spots. The project demonstrated the benefits of regional cooperation in planning and carrying out a jointly designed project.

Assessment of level of satisfaction of national health insurance scheme enrolees with services of an accredited health facility in Northern Nigerian

Introduction: Consumer satisfaction is one of the driving goals of goods and service production. Patient satisfaction surveys, as a means of periodic evaluation of the quality of services offered by the National Health Insurance Scheme (NHIS) accredited facilities, is necessary to ensure that the goals of the scheme are achieved and sustained. Materials and Methods: This was a cross-sectional study of 202 respondents randomly selected from NHIS enrolees attending the Staff Clinic of Aminu Kano Teaching Hospital. It assessed respondents' perceived waiting time, level of satisfaction at the clinic's service units, and overall clinic satisfaction using a modified general practice assessment questionnaire. Results: The mean age of respondents was 36.4 ± 8.1 with a near equal sex ratio. They were predominantly civil servants (79.2%) with tertiary education (75.7%). Most respondents (70.3%) felt waiting time was too long; with 79.7% of those, feeling they spend at least 30 min after arrival at the registration unit to see their doctor. A majority of respondents: 90.1%, 86.8%, 79%, 76.8%, 75.9%, 77.5%, and 80.6% were satisfied with the consultation time, doctors' consultation, medical records, pharmacy, laboratory, accounts, and nursing services, respectively. However, 65.8% were satisfied with the overall clinic services. The perceived sufficiency of the consultation time was associated with overall satisfaction (χ2 = 6.199, P = 0.013). Conclusion: Although 65.8% of respondents were satisfied with the clinic services, the perceived clinic waiting time was dissatisfactory; therefore, further studies on the determinants of overall satisfaction may be required if improvement in the proportion of satisfied service consumers is desired by the clinic managers
