    Effects of thermal and non-thermal pre-processing methods on the physical parameters of jackbean seed were investigated. The bean was subjected to three pre-processing methods roasting and autoclaving which are thermal and sprouting a non-thermal pre-processing method. The physical parameters evaluated include length, width and thickness which were done by the use of digital venier caliper, sphericity index by the use of formula and aspect ratio which is the ratio between length and width. The results of physical characterization revealed that all the pre-processing methods used had effects on the seed. With roasting, there was decrease in all these parameters except sphericity index: length 19.00– 15.00 mm, width 13.00–11.00 mm, thickness 10.75–10.55 mm and sphericity index 72.88–80.20 %. The aspect ratio decreased with pre-processing time for all the treatments used from 1.46- 1.33. Kernel density (g/cm3), bulk density (g/cm3) and density ratio for the untreated seed were 1.24, 0.73 and 0.59 respectively. However, with autoclaving and sprouting, there was increase in length from 19.00–24.00 mm, width 13.00–18.00 mm, thickness 10.75-11.10 mm but a decrease in sphericity index (72.88- 67.46 %) as the pre-processing time increased. These results are very useful in designing of processing equipment for the jackbean seeds thus, encouraging the industrial utilization of the seed.Keywords: Jackbean, roasting, autoclaving, sproutin

    The study aimed to determine the influence of nitric oxide (NO) on the action of histamine and carbachol on acid secretion in the common African toad – Bufo regularis. Gastric acidity was determined by titration method. The acid secretion was determined when nitric oxide was absent following administration of NO synthase inhibitor; N-nitro-L-arginine methyl ester (L-NAME) and when nitric oxide was in excess by administration of exogenous NO donor, sodium nitroprusside (SNP). Histamine or carbachol increased acid secretion in the toad. Acid output increased from 0.32 ± 0.04 mEq/15min to 0.56 ± 0.08 and 0.61 ± 0.05 mEq/15min for histamine and carbachol respectively (P < 0.05). Pretreatment of the toad with L-NAME produced further increases in histamine (0.62 ± 0.06 mEq/15min) or carbachol (0.74 ± 0.06 mEq/15min) induced acid secretion respectively. SNP however, completely abolished the acid secretion stimulated by either histamine or carbachol. It was therefore concluded that nitric oxide has a negative influence on the histamine or carbachol – stimulated acid secretion in the toad – Bufo regularis.Keywords: nitric oxide, histamine, carbachol, acid secretion Nigerian Journal of Physiological Sciences Vol. 20(1&2) 2005: 74-7

    Objectives: To determine the prevalence and describe factors associated with the use of potentially inappropriate medication (PIM) among older patients. Methods: Cross sectional study of 400 older patients selected systematically at the geriatric centre, University College Hospital, Ibadan between July and September 2016. With the aid of semi-structured questionnaires, information on the socio-demographic characteristics, lifestyle habits, healthcare utilisation and morbidities was obtained. The Beer’s criteria 2015 update was used to identify the PIMs. Predictors of PIMs were determined using multivariate analyses at alpha 0.05. Results: Age was 70.2 (SD=5.9) years and 240 (60%) were females. General prescription pattern showed antihypertensives (34.7%) as the commonest medications used. The point prevalence of PIMs use was 31%. In all, 10 PIMs were used by the respondents. The majority (81.5%) were using one PIM, while (17.7%) used two PIMs and (0.8%) 3 PIMs. NSAIDs (72.6%) were the commonest PIMs identified, followed by the benzodiazepines (24.2%). Respondents had an average of 1.9 morbidities, and mulitmorbidity found in 60.5%. Logistic regression analysis showed self-rated health assessed as better compared with age-mates [OR =1.718 (1.080–2.725)] and being physically active [OR =1.879 (1.026–3.436)] as the most significantly associated with PIMs use. Conclusions: The use of PIMs among older patients in our setting was high with NSAIDs being the most frequently used medications. An interdisciplinary approach, of medication review by pharmacists’, working with physicians may improve prescribing practices among older persons. Therefore, it is necessary to create public health awareness on the use of PIMs among older persons

    Reactive Oxygen Species (ROS) could be a causative factor for perfumeinduced testicular toxicity in male rats

    Fragrance materials have been implicated in male infertility. These ingredients are unsteady and tend to oxidize easily. The dearth of information regarding the mechanism of action in which it induces testicular toxicity prompted us to evaluate its possible mechanism pathway in animal model. Sixty adult male wistar rats were randomly divided into six groups of ten rats each. Group A and B rats (Controls) rats were exposed (6hrs day-1) to 5 ml kg-1 body weight of normal saline for 56 days and 112 days via whole body inhalation respectively, Group C and D rats were exposed (6hrs day-1) to 5 ml kg-1 body weight of one of the perfume designated as F1 for a period of 56 days and 112 days via whole body inhalation respectively while Group E and Group F rats were exposed (6hrs day-1) to 5 ml kg-1 body weight of one of the perfume designated as F2 for a period of 56 days and 112 days via whole body inhalation respectively. Result obtained showed a significant decrease in the activity level of SOD, CAT, GPx and GSH and a significant elevation in the level of MDA when compared to values from the control groups of rat. The decrease in level of these testicular enzymatic and testicular non-enzymatic antioxidants (SOD, CAT, GPx and GSH and MDA respectively) in group exposed for 112 days (D and F) were more significant (P<0.005) when compared to groups of rats exposed for 56 days (C and E). However, the GSH content in group E rats was not significantly (P>0.05) different from that of the control groups of rats. From our study, we can only conclude that oxidative stress in testicular tissue might be responsible, at least in part, for perfume induced toxicity in animal model

    Health workers sensitization: effects on perceived quality of immunization services among mothers of under five children in Ilorin, North Central Nigeria

    Clients? satisfaction with services received is an important dimen- sion of evaluation that is examined only rarely in developing coun- tries. Health care professionals have always acknowledged that satisfying the consumers at some level is essential to providing ser- vices of high quality. This is a quasi-experimental study. The study group included 150 mothers bringing their children for immuniza- tion at Alanamu Health Centre, Ilorin. The control group included 150 mothers bringing their children for immunization at Okelele Health Centre. Total population of mothers bringing their children for vaccines against tuberculosis/poliomyelitis/hepatitis B (BCG/ OPV/HBV) and against diphterite-pertussis-tetanus (DPT)/OPV/ HBV were recruited sequentially until sample size was attained. Mean waiting time at pre-intervention was 82.7 ± 32.5 and 90.4 ± 41.7 minutes for the study and control groups respectively. Post intervention, there was a significant decrease (p inf. 0.05) in the estimated waiting time in the study group (mean = 48.0 ± 24.4 minutes) while there was no observed difference in the control p &gt; 0.05 (mean = 88.4 ± 40.6 minutes). Perceived adequacy of information on services being provided by the health facility was low (58%) in the study group while it was relatively higher in the control group (80%), but there was a significant increase in pro- portion of those that felt information was adequate only in the study group (p inf. 0.05) at post intervention. Waiting time in health facili- ties by clients should be reduced as this may give clients a positive perception of the service they have come to access. Information dis- semination to clients should be encouraged among health workers as this would affect clients? knowledge and also quality of health care delivery

    Background. Cervical cancer is the second most common malig- nancy in women worldwide with a high incidence in under-devel- oped countries and Nigeria is one of these countries. This study aimed at screening for cervical cancer using Papanicolaou smear and to identify risk factors for cervical cancer among women in Olufadi community, Kwara state, North-central Nigeria. Methods. This was a cross-sectional study involving the screening of women aged 25-64 years for cervical cancer using Papanicolaou smear. Respondents were selected through systematic random sam- pling of households. Interviewer- administered questionnaire and clinical report form were also used to collect data. In addition, Pap smear samples were taken. Data was analyzed using SPSS version 15. Results. Only 10 (5.0%) respondents had positive cytology result, while the rest were normal. Of the 10 positive cytology results, 1(10.0%) was high grade squamous intraepithelial lesion (HGSIL) while the remaining 9(90.0%) were low grade squamous intraepithelial lesion (LGSIL) which corresponds to 0.5% and 4.5% of the total respondents respectively. Risk fac- tors for cervical cancer identified included coitarche, tobacco smoking, number of sexual partners and family history of cervi- cal cancer. Conclusion. The findings from this study attest to the increasing burden of cervical cancer. The high number of positive results obtained from the study coupled with the presence of risk factors was an indication of how useful regular screening will be in the early detection of cervical cancer

    Background Diabetes, particularly type 1 diabetes, at younger ages can be a largely preventable cause of death with the correct health care and services. We aimed to evaluate diabetes mortality and trends at ages younger than 25 years globally using data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. Methods We used estimates of GBD 2019 to calculate international diabetes mortality at ages younger than 25 years in 1990 and 2019. Data sources for causes of death were obtained from vital registration systems, verbal autopsies, and other surveillance systems for 1990–2019. We estimated death rates for each location using the GBD Cause of Death Ensemble model. We analysed the association of age-standardised death rates per 100 000 population with the Socio-demographic Index (SDI) and a measure of universal health coverage (UHC) and described the variability within SDI quintiles. We present estimates with their 95% uncertainty intervals. Findings In 2019, 16 300 (95% uncertainty interval 14 200 to 18 900) global deaths due to diabetes (type 1 and 2 combined) occurred in people younger than 25 years and 73·7% (68·3 to 77·4) were classified as due to type 1 diabetes. The age-standardised death rate was 0·50 (0·44 to 0·58) per 100 000 population, and 15 900 (97·5%) of these deaths occurred in low to high-middle SDI countries. The rate was 0·13 (0·12 to 0·14) per 100 000 population in the high SDI quintile, 0·60 (0·51 to 0·70) per 100 000 population in the low-middle SDI quintile, and 0·71 (0·60 to 0·86) per 100 000 population in the low SDI quintile. Within SDI quintiles, we observed large variability in rates across countries, in part explained by the extent of UHC (r2=0·62). From 1990 to 2019, age-standardised death rates decreased globally by 17·0% (−28·4 to −2·9) for all diabetes, and by 21·0% (–33·0 to −5·9) when considering only type 1 diabetes. However, the low SDI quintile had the lowest decline for both all diabetes (−13·6% [–28·4 to 3·4]) and for type 1 diabetes (−13·6% [–29·3 to 8·9]). Interpretation Decreasing diabetes mortality at ages younger than 25 years remains an important challenge, especially in low and low-middle SDI countries. Inadequate diagnosis and treatment of diabetes is likely to be major contributor to these early deaths, highlighting the urgent need to provide better access to insulin and basic diabetes education and care. This mortality metric, derived from readily available and frequently updated GBD data, can help to monitor preventable diabetes-related deaths over time globally, aligned with the UN's Sustainable Development Targets, and serve as an indicator of the adequacy of basic diabetes care for type 1 and type 2 diabetes across nations.publishedVersio

    Global burden of cardiovascular diseases and risk factors, 1990–2019: update from the GBD 2019 study

    Cardiovascular diseases (CVDs), principally ischemic heart disease (IHD) and stroke, are the leading cause of global mortality and a major contributor to disability. This paper reviews the magnitude of total CVD burden, including 13 underlying causes of cardiovascular death and 9 related risk factors, using estimates from the Global Burden of Disease (GBD) Study 2019. GBD, an ongoing multinational collaboration to provide comparable and consistent estimates of population health over time, used all available population-level data sources on incidence, prevalence, case fatality, mortality, and health risks to produce estimates for 204 countries and territories from 1990 to 2019. Prevalent cases of total CVD nearly doubled from 271 million (95% uncertainty interval [UI]: 257 to 285 million) in 1990 to 523 million (95% UI: 497 to 550 million) in 2019, and the number of CVD deaths steadily increased from 12.1 million (95% UI:11.4 to 12.6 million) in 1990, reaching 18.6 million (95% UI: 17.1 to 19.7 million) in 2019. The global trends for disability-adjusted life years (DALYs) and years of life lost also increased significantly, and years lived with disability doubled from 17.7 million (95% UI: 12.9 to 22.5 million) to 34.4 million (95% UI:24.9 to 43.6 million) over that period. The total number of DALYs due to IHD has risen steadily since 1990, reaching 182 million (95% UI: 170 to 194 million) DALYs, 9.14 million (95% UI: 8.40 to 9.74 million) deaths in the year 2019, and 197 million (95% UI: 178 to 220 million) prevalent cases of IHD in 2019. The total number of DALYs due to stroke has risen steadily since 1990, reaching 143 million (95% UI: 133 to 153 million) DALYs, 6.55 million (95% UI: 6.00 to 7.02 million) deaths in the year 2019, and 101 million (95% UI: 93.2 to 111 million) prevalent cases of stroke in 2019. Cardiovascular diseases remain the leading cause of disease burden in the world. CVD burden continues its decades-long rise for almost all countries outside high-income countries, and alarmingly, the age-standardized rate of CVD has begun to rise in some locations where it was previously declining in high-income countries. There is an urgent need to focus on implementing existing cost-effective policies and interventions if the world is to meet the targets for Sustainable Development Goal 3 and achieve a 30% reduction in premature mortality due to noncommunicable diseases
