RESUMEN
The study was done to determine the levels of interferon-gamma, interleukin 6, interleukin 10, iron status, hepcidin and haematologicalparameters of patients with pulmonary tuberculosis co-infected with human immunodeficiency virus in Southeast, Nigeria. This study was carried out at the directly observed treatment-short course Tuberculosis (TB DOTS) centre of Federal Medical Centre, Umuahia, located in South-Eastern Nigeria. Therefore, sample size of 240 was used to give room for attrition. A total of two hundred and forty (240) subjects aged 18-60 years were enlisted for this study. Seven milliliters (7ml) of venous blood was collected from each subject and 2.5ml was dispensed into bottles containing di-potassium salt of ethylenediamine tetra-acetic acid (K2-EDTA) and was used for full blood count, CD4 count and HIV screening. Also, 4.5ml was dispensed into plain tubes. Serum was obtained after clotting by spinning at 3000 RPM for 10 minutes and was used for interferon gamma, interleukin-6, and interleukin-10, iron and hepcidin determination. Data was analysed using statistical package for social science (SPSS) version 20. Student t-test, ANOVA (Analysis of Variance), Pearson Product Moment and Chi-Square were the tools employed. Results were expressed as mean ± standard deviation and are presented in table and significance level was set at P<0.05.The results showed difference that was statistically significant (P<0.05) in IFN-γ (P=0.000), IL-6 (P=0.000) IL-10 (P=0.000), CD4 (P=0.000), hepcidin (P=0.000), Iron (P=0.000), TIBC (P=0.000), %TSA (P=0.001) ,WBC (P=0.000), Neutrophils (P=0.000), Lymphocyes (P=0.000), Monocytes (P=0.000), Eosinophils (P=0.000), Basophils (P=0.018), RBC (P=0.000), haemoglobin (P=0.000), PCV (P=0.000), MCV (P=0.000), MCH (P=0.000), MCHC (P=0.000), Platelets (P=0.000), ESR (P=0.000) when compared among control, TB, HIV and TB-HIV subjects respectively. The co infection of HIV on pulmonary TB patients increases the levels of the cytokines. The cytokines and hepcidin can be used as adjunct to prognostic and diagnostic markers as their levels decreased with increased duration of treatment of the patients. The study hasshown wide variations in the haemtological indices studied
RESUMEN
Background: Hepatitis B and C viruses are common and preventable causes of liver disease. Health care workers are prone to infection by the hepatitis B and C viruses. In Nigeria there is no current guideline on vaccination of health care workers especially health care interns. Objective: To determine the knowledge, attitude and practice of health care interns and students towards hepatitis virus infection prevention. Methodology: This is a cross-sectional descriptive questionnaire-based study which was carried out among healthcare professional interns and medical students. Informed consent and ethical approval were obtained for this survey. Data entry and analysis was done using SPSS version 22 and appropriate descriptive statistics was applied. Results: A total of 253 interns of several healthcare professional groups and medical students took part in the survey. The healthcare interns were 115 (45.5%) and medical students were 138 (54.5%). They were 112 males (44.3%) and 141 females (55.7%), with age range 18-40 years and mean age of 22.9± 3.2 years. The respondents that knew that both hepatitis B and C were infective in nature were 225 accounting for 90.7% of respondents. The respondents with good knowledge on the modes of transmission of hepatitis were over 90% for known modes of transmission while those that knew of mother to child transmission accounted for 77.6% (n=180). Regarding the attitude of the respondents toward hepatitis B and C, only 60.4% (n=148) thinks that they are at risk of getting hepatitis infection. Those that have not received any form of hepatitis B vaccination were 163 accounting for 65.4% (n=163/253) of respondents. A high percentage of the respondents 97.8% (n=223/253) knew hepatitis B and C can cause liver disease. Conclusion: Despite a good knowledge of hepatitis B and C infectivity, attitude towards prevention of the infection was poor. The study reveals an urgent need for adequate and effective government and institutional policies towards prevention of viral hepatitis

RESUMEN
In developing countries; under nutrition is common; and this plays a crucial role in the pathogenesis of malaria and anemia. Indeed it has been associated with adverse pregnancy outcomes. Unfortunately; published evidence concerning the situation is lacking. Objectives: To evaluate some nutritional function indices of pregnant women in a rural Nigerian community. Subjects and Methods: This is a cross sectional study involving of 171 pregnant women from a rural area in South-eastern Nigeria. They included 72 and 99 women in their second and third trimesters respectively. The control group was of 60 women; matched in age; parity and socioeconomic conditions; non-pregnant; non-menstruating and non lactating apparently healthy women. The parameters measured by standard methods included serum iron; total proteins; albumin; globulin; packed cell volume and hemoglobin. Results: The results obtained from control group; second and third trimesters; recorded as Mean (SEM) were 134.60(3.12) ?g/L; 101.20(4.48) ?g/L and 91.87(3.42) ?g/L respectively for iron; 69.12(0.80) g/L; 63.60(0.71) g/L and 57.74(0.75) g/L for total proteins; 42.95(0.92) g/L; 35.74(1.00) g/L and 35.26(0.64) g/L for albumin; 26.77(1.00) g/L; 27.78(1.07) g/L and 22.93(0.88) g/L for globulin; 32.80(0.36); 27.92(0.37) and 27.73(0.34) for packed cell volume; and 11.25(0.11) g/L; 9.59(0.13) g/L and 9.57(0.14) g/L for hemoglobin respectively. These results showed that all the parameters decreased significantly in pregnancy (P0.001) except globulin that did not show immediate; significant decrease. Conclusion: There is a general decrease in the nutrition parameters studied among the pregnant women from our study area; indicating under-nutrition. Urgent measures should be taken to improve the nutritional status of rural dwellers especially the antioxidant micronutrients
