Effects of treated poultry litter on potential greenhouse gas emission and field agronomic performance

A study was conducted to evaluate the effects of different treatments of poultry faecal waste on potential greenhouse gas emission and inherent agronomic potentials. Sugar solution at 100g/l salt solution at 350g/l and oven-drying were the various faecal treatments examined using a completely randomized design. The experiment was conducted for eight weeks. Salt treatment had significantly lower nitrogen content (1.70%; p<0.05), and highest nitrogen depletion percentage (1.34%; p<0.05) while sugar treatment showed superiority in nitrogen trapping tendency, with depletion rate of -0.6%. Moisture content tends to increase significantly in sugar treatment (86.67%; p<0.05) and lowest with samples oven-dried (57.33%; p<0.05). Sugar treatment had a mildly acidic pH of 5.66, which was significantly lower (p<0.05) than was observed in Salt treatment (6.35). Salt treatment increased in weight over the 8weeks in storage (2.52kg, p<0.05), Sugar treatment weighed 2.28kg, heavier than oven-dried and control treatments (p<0.05), largely due to the process of fermentation. Baseline microbial assay studies shows no difference (p>0.05) in microbial count across all treatments, as was observed up till the 8th week. By the 4th week oven-dried faeces was lower (p<0.05) in fungal count (0.33×103cfu/ml) compared to other treatments, and completely devoid of Fungi by the end of the 8th week. On agronomic performance test, maize planted using sugar treatments had a 40% germination percentage (GP) after two weeks, oven-dry treatment and the control had mean GP of 65% and 75% respectively. The Sorghum plot attained 100% GP with the control and oven-dry treatments, sugar treatment recorded 88% GP. In both cases, germination was nil on salt treatment. By the third week ending, maize stands on control treatment were averagely 48cm tall, 19cm on oven-dried treatment and10cm on sugar treated pots. This trend persisted on sorghum plots with oven-dry treatment showing superiority to other treatments, averaging a plant height of 28cm after 21days. Key Words: Sugar, Salt, Oven-drying, Germination, Faecal waste, Fungal coun

Determinants of utilization of traditional bone setters in Ilorin, North Central Nigeria

Background. Traditional bone setting (TBS) practice is an important part of health care delivery in many developing coun- tries and has been in Nigeria for long. Despite the complications that arise from the cultural practice, TBS services is still in high demand by a significant number of people. This study was con- ducted to determine the factors that influence the utilization of TBS practice. Methods. A descriptive cross-sectional study was carried out using a semi structured questionnaire to gather information from 400 randomly selected residents of Ilorin West LGA in north cen- tral Nigeria. Multistage sampling technique was used in selecting the respondents. Results. The respondents were between the ages of 18-72 years with a mean age of 36.3 ± 12.3. Three hundred and three (77.3%) of the respondents know of TBS practice as a way of getting treat- ment for bone injuries. More than two third 210 (69.3%) of the respondents who know TBS practice as a form of treatment for bone injuries think that TBS therapy is preferable to Orthodox medicine in handling bone injuries. Reasons for preference are that it is cheap 134 (63.8%), acceptable 123 (58.6%) and accessible 109 (51.9%) to them. More than half (52.3%) of the respond- ents had patronized TBS treatment at one time or the other. Main reason for patronage of TBS was influence from family mem- bers and friends (53.6%). However, factors that influence the respondents decision to utilize TBS treatment include attitude of health workers 310 (77.5%), delay in hospitals 284(71.0%) fear of amputation 272 (54.35) and fear of operation 217(54.3%) in hospitals. There was a statistically significant (p inf. 0.05) relation- ship between respondents age, sex, marital status, occupation, ethnicity as well as the income level of the respondents and the utilization of TBS. Conclusions. Utilisation of TBS is quite popular among the stud- ied population because it is believed to be cheap, acceptable and accessible to them and a high proportion of the respondents uti- lize TBS notwithstanding that they live in a community where they have better access to orthodox medical care. Influence from fam- ily and friends is the main reason for consulting TBS. Regulations should be made concerning the advertisement of TBS practice by relevant agencies and the public should be made aware through health education on the dangers of TBS treatment

Determinants of Referral Practices of Clients by Traditional Birth Attendants in Ilorin, Nigeria

A sizeable number of deliveries still take place with the assistance of Traditional Birth Attendants in Nigeria. This study aims to determine the factors that determine the referral practices of the TBAs in Ilorin of high risk and complicated pregnancies. This descriptive study was conducted among all the 162 registered TBAs in Ilorin that were traceable using pre-tested semi-structured interviewer-administered questionnaire. About 90%, whose source of skill acquisition was by inheritance did not refer their clients appropriately compared with 48% of those whose source of skill acquisition was through formal training (p<0.05). The more the numbers of trainings, the more appropriate the referral (p<0.05). Having supervisory visit by qualified personnel is associated with appropriate referral practices (p<0.05). Regular training and re-training of TBAs with routine monitoring and supportive supervision will promote prompt referral of high risk and complicated pregnancies and deliveries (Afr. J. Reprod. Health 2010; 14[2]:77-84)

Community awareness of bird flu and the practice of backyard poultry in a North-Central State of Nigeria

Introduction. The practice of backyard poultry is a very common practice in many homes in Nigeria. Birds raised at home are usually free ranged, which increases close contact between man and birds, thus increasing the risk of transmission of avian influenza virus to man. This study investigated the awareness of bird flu infection and identifies risk factors associated with the practice of backyard/free ranged poultry among the residents of a state in Northern Nigeria. Methods. This cross-sectional study was carried out in Kwara State using 130 wards selected through cluster sampling technique. Households in each ward were sampled through systematic random sampling technique using the primary health care house numbering register. Semi-structured questionnaire was used to generate relevant information through interview and 650 participants consented and were used for the study. Results. Most of the respondents 604 (92.9%) kept birds in their homes and one-third 204 (33.8%) of this group knew that infection from birds can be transmitted to man. However, less than a third186 (30.8%) of those who keep birds were aware of avian influenza (AI) infection. Out of the 186 respondents, 78 (41.9%) had experienced massive bird deaths in the preceding year prior to the interview. Less than half 81 (43.5%) were willing to report AI or massive deaths occurring in flocks of their birds to designated officers / authority. During outbreaks with massive deaths in birds some of the respondents sold infected live birds 45 (57.7%), few slaughtered and dressed the birds before sale 11 (14.1%), while some slaughtered and consumed the birds in their families 19 (24.4%). Conclusion. The practice of backyard poultry is very high with little knowledge and awareness of mechanism and risk of infection associated with it. This was also reflected in their attitude towards reporting of outbreaks in birds. Public awareness campaign and home visit by environmental and veterinary officers are important strategies that can prevent AI infection transmission among domestic birds and man

Prevalence of stroke in three semi-urban communities in middle-belt region of Nigeria: A door to door survey

Introduction: the burden of stroke has been projected to increase for developing countries, but data are limited, especially in sub-Saharan Africa.This necessitated this study to determine the stroke prevalence in a semi urban community in middle-belt region of Nigeria. Methods: a twophasedoor-to-door study was performed in three semi-urban communities of  Kwara state; in the first phase 12,992 residents were screened andprobable stroke cases were identified by trained health care workers. In the second phase individuals adjudged to be positive for stroke were screened with a stroke-specific questionnaire and made to undergo a complete  neurological examination by a neurologist. Stroke diagnosis was based on clinical evaluation using WHO criteria. Results: out of the numbers that were screened, 18 probable stroke cases were identified in the first stage, and of these, 17 fulfilled WHO criteria for stroke, giving a crude prevalence rate of 1.31/1000 population. The prevalence of stroke was higher among the males than the females (1.54/1000 vs. 1.08/1000) with a ratio 1.4: 1. Sixteen subjects (94.1%) had one or more risk factors for stroke.  Uncontrolled systemic hypertension (82.4%) was the commonest risk  factors for stroke followed by transient ischaemic attack (TIA) (41.2%). Conclusion: stroke is a condition that is prevalent in our environment; especially in older adults and men. Uncontrolled systemic hypertension and previous transient ischaemic attacks were the commonest risk factors for stroke in our community

Vaccine Storage and Handling Practices among routine immunization service providers in a metropolitan city of North-Central Nigeria

Background: The efficacy of vaccines can be compromised by faulty transport, storage, and handling. This study was conducted to assess the knowledge and practice of vaccine storage and handling among Primary Health Care Workers (PHCWs) offering routine immunization (RI) services in static health facilities in Ilorin metropolis, North-central Nigeria.Methodology: It was a descriptive cross-sectional study carried out among 457 Primary Health Care Workers (PHCWs) in 2 Local Government Authorities in Kwara State, north central Nigeria, using multi stage sampling technique. The research instruments were pretested self-administered questionnaire and observational checklist. The data generated were analyzed using EPI-INFO version 3.5.1 software package. Level of significance was predetermined at p-value of less than 0.05 at 95% confidence interval.Results: About half of the respondents (52.1%) knew the optimal vaccine storage temperature, 35.4% knew that freezing is harmful to certain vaccines. Although, 67.8% were aware of the 'shake test', only 48.4% of them knew how to conduct it. Up to 367 (80.3%) acknowledged that heat is harmful to vaccines. Even though, 267 (58.4%) knew the vaccine vial monitor (VVM) stages, only 248 (45.3%) could interpret the VVM correctly. About 30% of the health facilities (HFs) had adequate vaccine storage equipments while less than one third (28.6%) refrigerators were used exclusively for vaccine storage. However, functioning thermometers were present in all the refrigerators devoted to vaccine storage.Conclusions: Vaccine storage and handling practices among PHCWs providing routine immunization (RI) services in the study area was still sub-optimal. There is need for periodic on the job training and supportive supervision of health workers by middle cadre immunization officers in the local government to improve on the vaccine storage and handling practices of RI service providers.Keywords: Routine immunization, knowledge, vaccine handling, Nigeria, practice

Malaria parasitaemia among blood donors in Ilorin, Nigeria

Background: The prevalence of malaria parasitaemia among blood donors in Ilorin has not been documented. In this study, we determined the prevalence of malaria parasitaemia among blood donors in Ilorin, as well as, the sociodemographic and other factors associated with it.Method: This was a hospital- based cross sectional study involving 308 consenting blood donors. The sociodemographic characteristics of participants as well as blood donation history were obtained using structured questionnaires specifically designed for this purpose. Giemsastained thick and thin blood films to identify malaria parasites were performed using standard method. ABO blood grouping and haemoglobin electrophoresis tests were also done using standard methods.Results: The prevalence of malaria parasitaemia among blood donors in Ilorin was 27.3%. The parasite species found were more of Plasmodium falciparum(85.7%) than Plasmodium malariae(14.3%) . There was no age or sex difference in malaria parasitaemia. (p-value of 0.8 and 0.32 respectively). A greater proportion of blood group O individuals had malaria parasitaemia than groups A and B but this difference was not significant (p-value = 0.13). There was also no significant difference among haemoglobin genotypes.Conclusion: The prevalence of malaria parasites among blood donors in Ilorin is considerably high and lack of routine screening of blood puts recipients at risk. We recommend that routine screening for malaria parasites be commenced in our blood banks. Treatment of donor blood with riboflavin and UV light to inactivate malaria parasites and other infectious pathogens before they are transfused to patients may also be considered in our blood banks.Key words: malaria, parasitaemia, blood donors, Nigeri

Reference values of haematological parameters of healthy adults in the north central zone of Nigeria

Background: Haematological parameters differ from one population to another due to several factors. To determine the clinical implication of the blood parameters of an individual in the state of health or disease, we need to have the knowledge of the normal reference range for that locality.Objectives: To determine the reference values of haematological parameters of apparently healthy adults in Ilorin.Design: A descriptive cross sectional study.Setting: Ilorin, North Central zone of NigeriaSubjects: Nine hundred and ten (443 males and 467 females) randomly selected normal, HIV negative individuals aged 18-65 yearsResults: The red blood cell count, Haemoglobin concentration, PCV and MCHC were significantly higher among males than females while the platelet count, total WBC count and absolute neutrophil count were significantly higher in females than in males. There was however no significant gender difference in the values of MCV, MCH and absolute lymphocyte count. The normal reference values obtained in this study were notably different from those that are used currently in the hospital.Conclusion: The normal reference value obtained in this study was notable different from those that are currently used in the hospital. These findings will have clinical implications regarding the adjustment of our current reference values and definitely add value to the management of patients in this part of the country

Pediatric Bacterial Meningitis Surveillance in Nigeria From 2010 to 2016, Prior to and During the Phased Introduction of the 10-Valent Pneumococcal Conjugate Vaccine

Background: Historically, Nigeria has experienced large bacterial meningitis outbreaks with high mortality in children. Streptococcus pneumoniae (pneumococcus), Neisseria meningitidis (meningococcus), and Haemophilus influenzae are major causes of this invasive disease. In collaboration with the World Health Organization, we conducted longitudinal surveillance in sentinel hospitals within Nigeria to establish the burden of pediatric bacterial meningitis (PBM). Methods: From 2010 to 2016, cerebrospinal fluid was collected from children <5 years of age, admitted to 5 sentinel hospitals in 5 Nigerian states. Microbiological and latex agglutination techniques were performed to detect the presence of pneumococcus, meningococcus, and H. influenzae. Species-specific polymerase chain reaction and serotyping/grouping were conducted to determine specific causative agents of PBM. Results: A total of 5134 children with suspected meningitis were enrolled at the participating hospitals; of these 153 (2.9%) were confirmed PBM cases. The mortality rate for those infected was 15.0% (23/153). The dominant pathogen was pneumococcus (46.4%: 71/153) followed by meningococcus (34.6%: 53/153) and H. influenzae (19.0%: 29/153). Nearly half the pneumococcal meningitis cases successfully serotyped (46.4%: 13/28) were caused by serotypes that are included in the 10-valent pneumococcal conjugate vaccine. The most prevalent meningococcal and H. influenzae strains were serogroup W and serotype b, respectively. Conclusions: Vaccine-type bacterial meningitis continues to be common among children <5 years in Nigeria. Challenges with vaccine introduction and coverage may explain some of these finding. Continued surveillance is needed to determine the distribution of serotypes/groups of meningeal pathogens across Nigeria and help inform and sustain vaccination policies in the countr

Psychological distress during pregnancy in a multi-ethnic community: findings from the born in Bradford cohort study

Purpose: Antenatal anxiety and depression are predictive of future mental distress, which has negative effects on children. Ethnic minority women are more likely to have a lower socio-economic status (SES) but it is unclear whether SES is an independent risk factor for mental health in pregnancy. We described the association between maternal mental distress and socio-demographic factors in a multi-ethnic cohort located in an economically deprived city in the UK. Methods: We defined eight distinct ethno-language groups (total N = 8,454) and classified a threshold of distress as the 75th centile of within-group GHQ-28 scores, which we used as the outcome for univariate and multivariate logistic regression for each ethnic group and for the sample overall. Results: Financial concerns were strongly and independently associated with worse mental health for six out of the eight ethnic groups, and for the cohort overall. In some groups, factors such as working status, education and family structure were associated with worse mental health, but for others these factors were of little importance. Conclusions: The diversity between and within ethnic groups in this sample underlines the need to take into consideration individual social, migration and economic circumstances and their potential effect on mental health in ethnically diverse areas
