Potential impact of husbandry practices on the welfare and productivity of draught cattle in rural communities around Zaria, Nigeria

A survey of the draught cattle husbandry practices and the potential impact of such practices on the health and productivity as it relates to work hours of these cattle was carried out during the months of November – March (dry season) and during the months of June-September (wet season) in seven rural communities around Zaria. It was observed that these animals are kept under a typical traditional husbandry system, where no special housing or periodic health care is provided for these animals. Consequently, common health conditions seen were more during the dry season, (64.75%) than during the wet period (38.72%). The clinical parameters of the apparently healthy draught cattle as compare to those clinically sick showed significant changes in the age, weight, working hours and work output. The variation in the body weight showed that clinically sick cattle with diarrhea had significantly (P<0.05) lower weight than those with injuries, and mixed conditions. The body temperatures of those injured and with mixed conditions were significantly (P<0.05) higher than those with diarrhea and other conditions. It was concluded that clinically sick cattle showed loss of weight, worked less hours and consequently less output than the healthy cattle. Factors that affect the health management of draught animals such as the availability of quality food supply, the level of hygiene, the prevalence of diseases and available veterinary services were noticed to be present in these communities. The draught animal survival ability rather than productive ability was the dominating factor in most husbandry practice in these communities, with the animals surviving under sub-optional productive state in conjunction with stress of diseases on one hand, and poor nutrition on the other hand.Keywords: Draught Cattle, Husbandry, Health, Workhours, Wet, Dry Month

Global, regional, and national disability-adjusted life-years (DALYs) for 315 diseases and injuries and healthy life expectancy (HALE), 1990�2015: a systematic analysis for the Global Burden of Disease Study 2015

Background Healthy life expectancy (HALE) and disability-adjusted life-years (DALYs) provide summary measures of health across geographies and time that can inform assessments of epidemiological patterns and health system performance, help to prioritise investments in research and development, and monitor progress toward the Sustainable Development Goals (SDGs). We aimed to provide updated HALE and DALYs for geographies worldwide and evaluate how disease burden changes with development. Methods We used results from the Global Burden of Diseases, Injuries, and Risk Factors Study 2015 (GBD 2015) for all-cause mortality, cause-specific mortality, and non-fatal disease burden to derive HALE and DALYs by sex for 195 countries and territories from 1990 to 2015. We calculated DALYs by summing years of life lost (YLLs) and years of life lived with disability (YLDs) for each geography, age group, sex, and year. We estimated HALE using the Sullivan method, which draws from age-specific death rates and YLDs per capita. We then assessed how observed levels of DALYs and HALE differed from expected trends calculated with the Socio-demographic Index (SDI), a composite indicator constructed from measures of income per capita, average years of schooling, and total fertility rate. Findings Total global DALYs remained largely unchanged from 1990 to 2015, with decreases in communicable, neonatal, maternal, and nutritional (Group 1) disease DALYs offset by increased DALYs due to non-communicable diseases (NCDs). Much of this epidemiological transition was caused by changes in population growth and ageing, but it was accelerated by widespread improvements in SDI that also correlated strongly with the increasing importance of NCDs. Both total DALYs and age-standardised DALY rates due to most Group 1 causes significantly decreased by 2015, and although total burden climbed for the majority of NCDs, age-standardised DALY rates due to NCDs declined. Nonetheless, age-standardised DALY rates due to several high-burden NCDs (including osteoarthritis, drug use disorders, depression, diabetes, congenital birth defects, and skin, oral, and sense organ diseases) either increased or remained unchanged, leading to increases in their relative ranking in many geographies. From 2005 to 2015, HALE at birth increased by an average of 2·9 years (95 uncertainty interval 2·9�3·0) for men and 3·5 years (3·4�3·7) for women, while HALE at age 65 years improved by 0·85 years (0·78�0·92) and 1·2 years (1·1�1·3), respectively. Rising SDI was associated with consistently higher HALE and a somewhat smaller proportion of life spent with functional health loss; however, rising SDI was related to increases in total disability. Many countries and territories in central America and eastern sub-Saharan Africa had increasingly lower rates of disease burden than expected given their SDI. At the same time, a subset of geographies recorded a growing gap between observed and expected levels of DALYs, a trend driven mainly by rising burden due to war, interpersonal violence, and various NCDs. Interpretation Health is improving globally, but this means more populations are spending more time with functional health loss, an absolute expansion of morbidity. The proportion of life spent in ill health decreases somewhat with increasing SDI, a relative compression of morbidity, which supports continued efforts to elevate personal income, improve education, and limit fertility. Our analysis of DALYs and HALE and their relationship to SDI represents a robust framework on which to benchmark geography-specific health performance and SDG progress. Country-specific drivers of disease burden, particularly for causes with higher-than-expected DALYs, should inform financial and research investments, prevention efforts, health policies, and health system improvement initiatives for all countries along the development continuum.

Seroprevalence of contagious bovine pleuropneumonia in three selected south-eastern states of Nigeria

Contagious bovine pleuropneumonia is a trans-boundary animal disease caused by Mycoplasma mycoides subsp. mycoides. This study was designed to determine the seroprevalence of contagious bovine pleuropneumonia (CBPP) in three selected south eastern states (Anambra, Enugu and Imo) of Nigeria using competitive enzyme-linked immunosorbent assay (c-ELISA). A total of 438 bovine sera samples were collected randomly for four months (December 2019 to March 2020) and screened for antibodies to Mycoplasma mycoides subsp. mycoides (Mmm) using IDEXX CBPP antibody ELISA kit (CIRAD, France). Results showed an overall prevalence of 59.4% for the three states screened. Antibodies to Mmm were detected in all the three states. Enugu state had the highest prevalence (64.3%) followed by Imo state (63%) and Anambra state (50.7%). Female animals had higher prevalence of CBPP than male. However, it was not statistically significant (P> 0.05). This study confirms the presence of CBPP in south eastern Nigeria, and could be used as a base line data for future studies in this region. It is recommended that active surveillance and vaccination protocol should be undertaken in the region for the control and prevention of this disease.

Sleeping space matters: LLINs usage in Ghana

Long Lasting Insecticidal Net (LLIN) is an effective malaria prevention mechanism. However, ownership of LLIN does not imply its use among households. The availability of enough sleeping space is a natural prerequisite to install and use LLINs. The objective of this study was to explore the effect of sleeping space and other socio-demographic factors of households’ heads on LLINs usage among households. A cross-sectional household-based study was conducted using a quantitative approach. Data was collected exclusively from households that received LLINs at no direct financial cost to them in a mass malaria campaign conducted in the study area using a structured questionnaire. A total of 383 households sampled for the study received 1,181 LLINs with a range of 1 to 15 LLINs per household. Less than 16% of households that received more than 2 LLINs installed all the LLINs they received during the distribution. Among households that received LLINs, 45% of them did not use them at all and 36% of them used them every night including the night before data collection. The number of bedrooms, children and members per household, and the number of occupants per bedroom were also found statistically associated with the use of LLINs among households. The study used a quantitative approach to investigate sleeping space in relation to LLINs usage and malaria control, an area and topic that has not been adequately covered in the literature

Knowledge levels on applications of radiation in medicine among medical practitioners in Ghana

The evaluation of medical practitioners’ knowledge levels of radiation and safety is essential for planning diagnostic procedures and treatment in radiation medicine. This study sought to identify levels of knowledge and the predictor variables influencing knowledge of medical practitioners on applications of radiation in medicine in Ghana. Online survey was conducted with Google Form consisting of 37-point questionnaire highlighting on physicians’ background information, professional experience, knowledge on radiation usage in medicine, radiation protection and safety. Evaluation of the data was performed by descriptive analysis using frequency distributions and percentages. Among 152 respondents who participated in the study, specialists and consultants made up a higher representation of 46.7%. Two-thirds (64.0%) of the respondents who had received refresher training in the application of radiation in medicine exhibited full knowledge in the field. Medical practitioners who had practiced between 21–25 years were also found to demonstrate full knowledge of the application of radiation in medicine, while 36.6% of those who had practiced for < 6 years demonstrated extensive knowledge. Majority of the medical practitioners, constituting 39.5%, exhibited full knowledge in medical radiation protection and safety. This level of knowledge was found higher than what was demonstrated for general and occupational radiation protection. With medical imaging forming a key component in the diagnosis of several medical conditions, education in the field of radiation usage and radiological protection and safety should be a subject of periodic training for medical practitioners regardless of their level of training or duration of practic

Healthcare access and quality index based on mortality from causes amenable to personal health care in 195 countries and territories, 1990-2015: A novel analysis from the global burden of disease study 2015

Background National levels of personal health-care access and quality can be approximated by measuring mortality rates from causes that should not be fatal in the presence of effective medical care (ie, amenable mortality). Previous analyses of mortality amenable to health care only focused on high-income countries and faced several methodological challenges. In the present analysis, we use the highly standardised cause of death and risk factor estimates generated through the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) to improve and expand the quantification of personal health-care access and quality for 195 countries and territories from 1990 to 2015. Methods We mapped the most widely used list of causes amenable to personal health care developed by Nolte and McKee to 32 GBD causes. We accounted for variations in cause of death certification and misclassifications through the extensive data standardisation processes and redistribution algorithms developed for GBD. To isolate the effects of personal health-care access and quality, we risk-standardised cause-specific mortality rates for each geography-year by removing the joint effects of local environmental and behavioural risks, and adding back the global levels of risk exposure as estimated for GBD 2015. We employed principal component analysis to create a single, interpretable summary measure-the Healthcare Quality and Access (HAQ) Index-on a scale of 0 to 100. The HAQ Index showed strong convergence validity as compared with other health-system indicators, including health expenditure per capita (r=0·88), an index of 11 universal health coverage interventions (r=0·83), and human resources for health per 1000 (r=0·77). We used free disposal hull analysis with bootstrapping to produce a frontier based on the relationship between the HAQ Index and the Socio-demographic Index (SDI), a measure of overall development consisting of income per capita, average years of education, and total fertility rates. This frontier allowed us to better quantify the maximum levels of personal health-care access and quality achieved across the development spectrum, and pinpoint geographies where gaps between observed and potential levels have narrowed or widened over time. Findings Between 1990 and 2015, nearly all countries and territories saw their HAQ Index values improve; nonetheless, the difference between the highest and lowest observed HAQ Index was larger in 2015 than in 1990, ranging from 28·6 to 94·6. Of 195 geographies, 167 had statistically significant increases in HAQ Index levels since 1990, with South Korea, Turkey, Peru, China, and the Maldives recording among the largest gains by 2015. Performance on the HAQ Index and individual causes showed distinct patterns by region and level of development, yet substantial heterogeneities emerged for several causes, including cancers in highest-SDI countries; chronic kidney disease, diabetes, diarrhoeal diseases, and lower respiratory infections among middle-SDI countries; and measles and tetanus among lowest-SDI countries. While the global HAQ Index average rose from 40·7 (95% uncertainty interval, 39·0-42·8) in 1990 to 53·7 (52·2-55·4) in 2015, far less progress occurred in narrowing the gap between observed HAQ Index values and maximum levels achieved; at the global level, the difference between the observed and frontier HAQ Index only decreased from 21·2 in 1990 to 20·1 in 2015. If every country and territory had achieved the highest observed HAQ Index by their corresponding level of SDI, the global average would have been 73·8 in 2015. Several countries, particularly in eastern and western sub-Saharan Africa, reached HAQ Index values similar to or beyond their development levels, whereas others, namely in southern sub-Saharan Africa, the Middle East, and south Asia, lagged behind what geographies of similar development attained between 1990 and 2015. Interpretation This novel extension of the GBD Study shows the untapped potential for personal health-care access and quality improvement across the development spectrum. Amid substantive advances in personal health care at the national level, heterogeneous patterns for individual causes in given countries or territories suggest that few places have consistently achieved optimal health-care access and quality across health-system functions and therapeutic areas. This is especially evident in middle-SDI countries, many of which have recently undergone or are currently experiencing epidemiological transitions. The HAQ Index, if paired with other measures of health-system characteristics such as intervention coverage, could provide a robust avenue for tracking progress on universal health coverage and identifying local priorities for strengthening personal health-care quality and access throughout the world.
