Sputum smear positive tuberculosis among pulmonary tuberculosis patients at university of maiduguri teaching hospital: a retrospective study

The identification of sputum smear positive pulmonary tuberculosis cases is recommended by the World Health Organisation (WHO) as part of its directly observed therapy short course (DOTs) for effective global tuberculosis control. Earlier study performed in this centre (University of Maiduguri Teaching Hospital (UMTH) Maiduguri) showed a relatively small prevalence of sputum smear positivity among Pulmonary Tuberculosis (PTB) patients that is not close to the Millennium Development Goals (MDG). Objectives: To determine the prevalence of sputum smear positive tuberculosis and assess the progress so far, 5 years after the earlier study. Methods: This is a retrospective study, where the records of all patients treated for tuberculosis at UMTH between April 2008 and December 2008 were retrieved and analysed. Demographic data of PTB patients and their results of sputum smear, stained by Ziehl-Neelson technique were obtained. The effect of HIV seropositivity and of its treatment using HAART on sputum smear was assessed. Results: Four hundred and thirty nine patients with PTB aged 14 years and above consisting of 254(57.9%) males and 185(42.1%) females were used for this study. The 20-25 year age group had the highest sputum smear positive cases, while those within the 62-67 year age group had the lowest. One hundred and eight patients (41.4%) had sputum smear positive results while 153(58.6%) patients had negative smears. Nosignificant difference in sputum positivity between HIV negative and HIV positive patients. Conclusion: The higher rate of sputum smear positive pulmonary TB cases showed an increase in detection rate compared with an earlier finding, but is still some miles away from the set target (MDG goals)

Analysis of Conduct and Performance of Dried Fish Market in Maiduguri Metropolis of Borno State, Nigeria

The study analyzed conduct and performance of dried fish markets in Maiduguri Metropolis of Borno State, Nigeria. Data were obtained using structured questionnaire. Three (3) major dried fish markets were purposely selected out of the seven (7) markets in the study area to reflect areas where dried fish is predominantly sold. A total of 100 respondents from the three (3) markets were randomly selected for the study. Descriptive statistics and budgetary techniques were used as analytical tools. The finding of the study reveals that (44.82%) and (33.33%) were obtained as market margin from sales of Grade C and Grade A dried fish respectively. The result of marketing cost and returns also reveals that capital invested constitutes (96.08%) of the total fixed cost, while transportation accounts for (30.55%) of the total variable cost. The result of market return (net returns) reveals that N25, 013,440.04 was obtained as net returns per week. The finding on marketing efficiency reveals (67.33%) was obtained per cartoons of dried fish sold. The result further indicates the efficiency ratio of 95.54 which is positive. The result of the market conduct reveals that about (40%) of the marketers get information on market situation through personal contact, (72%) price haggling, while (56%) said prices were set by both the sellers and the agents. It was recommended that local fish marketers should be organized into cooperative groups and government should adequately provide infrastructural facilities such as good roads and market facilities to dried fish marketers in the study area.

Gender Difference in Students’ Academic Performance in Colleges of Education in Borno State, Nigeria: Implications for Counselling

This study examines the differences between students’ gender and academic achievement in Colleges of Education in Borno State. The study set one research objective, one research question and tested one research hypothesis. the population of this study include all the NCE students from three NCE awarding institutions in the state that were purposively selected for the study, the Krejcie and Morgan method of selecting sample was employed to choose (322) participants and proportionate techniques was also used to draw186 students out of 351 NCE III students’ in Kashim Ibrahim College of Education, Maiduguri and 136 students out of 210 NCE III students in Umar Ibn Ibrahim College of Education, Science and Technology, Bama. Students’ Academic Performance Aptitude Test (SAPAT) r=0.62 was used by the researchers. T-test was used to test the hypothesis raised in this study. The results indicated that there was no significant differences exist between gender and Academic performance in Colleges of Education in Borno State, in favour of female students therefore, the null hypothesis was accepted. The recommendation advanced was that: the male students lack pocket money thus, and state government should increase their annual scholarship so as to support their academic activities

Agulhas ring dynamics from TOPEX/POSEIDON satellite altimeter data

The transfer of warm water from the Indian Ocean into the South Atlantic subtropical gyre takes place in the form of rings and filaments formed when the Agulhas Current retroflects south of Africa between 15 and 25E. A survey of the rings formed from September 1992 until December 1995 in the Retroflection region was carried out using TOPEX/POSEIDON altimeter data. A two-layer model was used to estimate the upper layer thickness from the altimeter-derived sea-surface height anomaly data. An objective analysis scheme was used to construct a map of upper layer thickness every ten days. Seventeen rings and their trajectories were identified using these maps. The shedding of rings from the Agulhas Current was neither continuous nor periodic, and for long periods there is no formation of rings. Several rings remained in the region for more than a year and, at any given time, 2 to 6 rings coexisted in the region east of the Walvis Ridge. The results showed that the number of rings translating simultaneously in this region is larger during the first half of each year. The upper layer transport of the Agulhas Current in the Retroflection region was computed and a close association between high variations in transport and ring shedding was found. Rings translated WNW at translation speeds ranging from 5 to 16 km day−1 following formation. The values of available potential energy computed for the rings place them among the most energetic rings observed in the world oceans, with values of up to 70 × 1015 J. Transport computations indicate that each ring contributes in the average approximately 1 Sv of Agulhas Current waters to the Benguela Current

Determination of minerals, vitamins, antinutrient and amino acid profile of pumpkin pie produced pumpkin (cucurbeta spp) puree and wheat (tritium aestivum) flour supplemented with spices and butter

Pumpkin (Cucurbita spp.), is one of the most popular vegetables consumed in the world, has been recently recognized as a functional food. Traditional crops including the pumpkins, which are rich in micronutrients, are not consumed widely by smallholder farmers in Africa. However, the cultivation of high yielding, nutrient-rich, multipurpose crops-like pumpkin is important in solving the problems of malnutrition and contributing to food security in Africa including Nigeria. Objectives: Therefore, this work aimed at producing Pumpkin pie from Pumpkin puree and wheat supplemented with some indigenous spices alongside butter. Methodology: Formulations into various formed were made using Pearson's method. The formulations were assayed for mineral, vitamin, antinutrient and amino acid composition using standard laboratory methods. A significant (P<0.05) difference was observed in Zn and Ca content of all the samples, with sample D recording the highest value for Zn (1.30±0.01) mg/g and Ca (0.47±0.01) mg/g. However, samples A and D had the least values for Na and Fe. An increasing and decreasing pattern was observed in all the vitamin contents(B 1, B 2 , B 6 , B12 and C), moving from samples A through to D. Vitamin contents of samples B1 and B6 and higher than he RDA, while B2 , B12 and C were below RDA. The overall antinutrient contents observed were generally low, with sample A having the lowest values for Phytate, Oxalate and tannins. The B, C and D are more enhanced in terms of essential amino acids compared to the control group (sample A). Conclusion: Pumpkin pie can be produced from pumpkin and its supplementation of the spices can boost the pie with essential amino acids, minerals, and vitamin composition. This shows the potential of using pumpkin pie as snacks in-between meals for the prevention of Protein Energy Malnutrition (PEM).&nbsp

Sputum smear positivity among patients presenting to the dots clinic with chronic cough

Cough is one of the cardinal features of Pulmonary Tuberculosis (PTB). However, even in communities with high prevalence of TB, lung diseases other than TB appear to account for this symptom. Objective: To estimate the prevalence of sputum smear positivity among patients with TB who presented with complaints of chronic cough to the Directly Observed Therapy Short Course (DOTS) clinic at the University of Maiduguri Teaching Hospital, North Eastern Nigeria. Methodology: A cross sectional study was conducted at the University of Maiduguri Teaching Hospital (UMTH) Borno state, Northeastern Nigeria between September 2014 and January 2017. All patients (new or previously treated) who presented to the DOTS clinic of the UMTH with complaints of chronic cough and had screening for pulmonary TB using sputum smear microscopy were reviewed. The minimum and the maximum ages were 1 year and 85 years, respectively, and the mean age was 36.0 (SD=14.0) years. The mean age did not differ among the male and female patients (i.e.37.3 ± 14.4 vs 34.1 ± 13.2, p=0.78). The overall prevalence of sputum smear positivity for TB was 26.5%. Although majority of patients who were sputum smear positive for TB fell within the age groups 30-39 and 20-29 thus accounting for 42.6% and 28.7% respectively, however, there was no significant association between age of those with chronic cough and sputum smear positivity TB (p=0.80). Among those who were sputum smear positive, 24.3% were new cases and 2.2% were previously treated. Conclusions: Data were entered into a computer database and analyzed with SPSS version 20.0 statistical software. Results: This study showed a high prevalence of sputum smear positivity among suspected TB patients with complaints of chronic cough This could be explained by the fact that the DOTS strategy has improved the case detection of PTB in this community. All patients with chronic cough should be evaluated for PTB

Prevalence of microalbuminuria in untreated Nigerian hypertensive patients

The burden of cardiovascular disease imposed by hypertension is a result of target organ damage. Microalbuminuria (MA) is the first clinical expression of nephropathy and has become acardiovascular and/or renal disease prognostic indicator for hypertensive subjects. Objectives: To establish the prevalence of MA among newly diagnosed hypertensive patients using thesimple spot urine Albumin-Creatinine Ratio (ACR). Method: : One hundred and eighty six newly diagnosed hypertensive patients were enrolled for assessment of MA using spot urine ACR. Those with overt proteinuria, diabetes mellitus, overt kidney disease and other potential causes of albuminuria were excluded. Spot urine was obtained for measurement of albuminand creatinine. Anthropometric variables were measured and body mass index calculated. All patients had echocardiographic assessment. Statistical analysis was performed using SPSS version 11.0 software. Multiple regression analysis was used in determining predictors of MA. A p-value of ≤ 0.05 was considered significant. Results: Results of 136 patients comprising of 66(48.53%) males and 70(51.47%) females was considered. The overall prevalence of microalbuminuria was 42.65%. Males had a prevalence of 51.52% compared to 34.27% for the females (p=0.29). Weight, BMI, LVM, LVMI, UAE, and ACR were significantly higher in patients with MA, whereas those without MA had a significantly higher urinary creatinine. Multiple regression analysis identified DBP, MAP, LVM and LVMI as significant predictors of increased urinary albumin excretion Microalbuminuria showed significant positive correlation with LVM and LVMI. Conclusion: The prevalence of microalbuminuria is high among untreated Nigerian hypertensive patients. The spot urine ACR provides a simple, accurate and cost effective way of identifying this high risk group of hypertensive patients, allowing for more aggressive treatment to reduce cardiovascular outcomes

Hepatic transaminase and alkaline phosphatase enzyme levels in HIV/HBV co‑infected and HIV mono‑infected patients in Maiduguri, Nigeria

Background: Studies have shown that HIV‑HBV co‑infected patients have an increased risk of liver‑related morbidity and mortality compared to their HIV‑mono‑infected counterparts. Furthermore, it has been reported that HIV‑HBV co‑infected patients have a significantly high incidence of drug‑induced hepatotoxicity following commencement of HAART than HIV‑mono‑infected patients.Objectives: To compare the levels of aspartate amino transferase (AST), alanine amino transferase (ALT) and alkaline phosphatase (ALKPO4) enzyme levels between HAART naïve HIV‑HBV co‑infected patients and their HIV‑mono‑infected counterparts.Materials and Methods: A cross‑sectional descriptive study in which 142 newly diagnosed HIV/HBV co‑infected and HIV mono‑infected adults were investigated for alkaline aminotransferase, aspartate aminotransferase and alkaline phosphatase enzyme levels.Results: The study subjects comprised of 80 (56.3%) females and 62 (46.7%) males. The age range of the study population was 15‑65 years. The mean ages of male and female subjects were 45.5 ± 10.5 years and 39.1 ± 7.5 years respectively (P < 0.05). Sixty‑three (44.4%) study subjects were HIV/HBV co‑infected while 79 (55.6%) were HIV mono‑infected. The mean ALT enzyme level of HIV/HBV co‑infected subjects was significantly higher than that of HIV mono‑infected ones i.e., 42.12 IU/l vs. 27.86 IU/l, (P = 0.038). However, there was no statistically significant difference in the mean AST (30.14 IU/l vs. 29.09 IU/l, P = 0.893) and ALKPO4 (55.86 IU/l vs. 60.97 IU/l, P = 0.205) enzyme levels between HIV‑HBV co‑infected and HIV mono‑infected subjects albeit the two enzymes were moderately elevated in both categories of subjects.Conclusion: The significantly elevated ALT enzyme levels amongst HIV‑HBV co‑infected subjects suggest that HIV‑HBV co‑infected patients may have an increased risk of liver‑related morbidity and mortality than their HIV mono‑infected counterparts. Screening for serological markers of chronic HBV infection, as well as hepatic transaminase enzyme levels in all newly diagnosed HIV‑positive patients is therefore recommended before commencement of HAART.Keywords: Alkaline phosphatase enzyme, hepatitis B virus surface antigen, hepatic transaminase enzymes, human immunodeficiency virusNigerian Journal of Clinical Practice • Oct-Dec 2013 • Vol 16 • Issue

Insulator-Metal Transition in One Dimension Induced by Long-Range Electronic Interactions

The effects of a long range electronic potential on a one dimensional commensurate Charge Density Wave (CDW) state are investigated. Using numerical techniques it is shown that a transition to a metallic ground state is reached as the range of the electron-electron repulsion increases. In this metallic state, the optical conductivity exhibits a large Drude weight. Possible interpretations of our results are discussed.Comment: 5 pages, Revtex, minor misprints corrected and a reference to earlier work by V. Emery and C. Noguera adde

Distribution and sources of organic matter in surface marine sediments across the North American Arctic margin

As part of the International Polar Year research program, we conducted a survey of surface marine sediments from box cores along a section extending from the Bering Sea to Davis Strait via the Canadian Archipelago. We used bulk elemental and isotopic compositions, together with biomarkers and principal components analysis, to elucidate the distribution of marine and terrestrial organic matter in different regions of the North American Arctic margin. Marked regional contrasts were observed in organic carbon loadings, with the highest values (1 mg C m(-2) sediment) found in sites along Barrow Canyon and the Chukchi and Bering shelves, all of which were characterized by sediments with low oxygen exposure, as inferred from thin layers (\u3c2 \u3ecm) of Mn oxihydroxides. We found strong regional differences in inorganic carbon concentrations, with sites from the Canadian Archipelago and Lancaster Sound displaying elevated values (2-7 wt %) and highly depleted C-14 compositions consistent with inputs from bedrock carbonates. Organic carbon:nitrogen ratios, stable carbon isotopes, and terrigenous organic biomarkers (lignin phenols and cutin acids) all indicate marked regional differences in the proportions of marine and terrigenous organic matter present in surface sediments. Regions such as Barrow Canyon and the Mackenzie River shelf were characterized by the highest contributions of land-derived organic matter, with compositional characteristics that suggested distinct sources and provenance. In contrast, sediments from the Canadian Archipelago and Davis Strait had the smallest contributions of terrigenous organic matter and the lowest organic carbon loadings indicative of a high degree of post-depositional oxidation
