The biochemical tests conducted includes include Citrate Utilization test, Triple Sugar Iron test, Urea test, Methyl Red test, Indole test, and Voges Proskauer test. The isolates were confirmed by Microbact<sup>TM</sup>GNB24E identification kit (Oxiod, UK). A total of 400 fish samples were bought in the market from three area council of the FCT. The result of the study showed overall prevalence rate of (13) 3.25% of Proteus mirabilis isolates. Distribution based on Area councils showed that AMAC had higher prevalence rate of 4.81%, while Bwari had 2.99% and Gwagwalada with 2.57% prevalence. All isolates were subjected to antimicrobial susceptibility testing using the modified single disc diffusion method. From the antimicrobial susceptibility testing done it was discovered that Proteus mirabilis are resistant to Amoxyclav (100%), Erythromycin (92.3%), Tetracycline (92.3%) and Ceftriaxone (23.1%). However, the isolates were susceptible to Ofloxacin (100%), Netillin (92.3%), Levofloxacin (92.3%), Ceftazidime (76.9%), Co-trimoxazole (69.2%) and Gentamicin (61.5%). Since Proteus mirabilis sources of zoonotic diseases and can potentially be dangerous to humans and other animals, our research was able to isolate it from fresh water fish sold in the Federal Capital Territory. This makes public health awareness of the risks associated with Proteus mirabilis in Nigeria necessary.展开更多

Pharmacy staffs have pivotal roles in facilitating the prudent use of antibiotics through antimicrobial stewardship programs. Due to limited information in Benin, this study assessed the knowledge and attitudes of pharmacy staffs on antibiotic use and resistance. Materials and Methods: This cross-sectional study was conducted among 159 pharmacy staffs using a structured questionnaire from August 2018 to December 2018 in Benin. Data analysis was done by using Stata version 13.0. Results: Of the 159 participants, 54.8% knew the definition of antibiotic therapy and 66.9% knew the definition of probabilistic antibiotic therapy. The majority (88.1%) of the participants thought that the choice of antibiotics was made according to the pathology, while 60.4% thought that it depended on the pathology and the germ involved. 49.02% of dispensers in pharmacies stated that half of the patients had requested treatment without providing a prescription at the pharmacy. The top three antibiotics that were dispensed without a prescription include amoxicillin (98.1%), cloxacillin (76.7%) and metronidazole (57.2%), all from the Access group of antibiotics. Conclusion: These results underscore the need for educational and training interventions targeting specific professional groups. There is an urgent need for regulatory measures and public awareness through improved antimicrobial stewardship to limit this practice.展开更多

The aim of this study was to analyze the cardiovascular risk factors in hypertensive farmers compared with hypertensive non farmers. This was a prospective case-control study that included 239 hypertensive farmers and non farmers aged 25 to 65 with blood pressure ≥ 140 mmHg and 90 mmHg. Hypertensive farmers (101) represented 42.25% of the population versus hypertensive non farmers (138) 57.74%. The median ages were 47 ± 11.3 years for farmers and 51.45 ± 9.77 years for non farmers. Biochemical analysisand screening for major cardiovascular disease risk factors such as metabolic syndrome were performed. Metabolic syndrome was defined according to the new definition of the International Diabetes Federation. Our results revealed higher blood glucose levels in farmers (47.77%) than in non farmers (27.20%) (p = 0.0132). Dyslipidemia was more frequent in non farmerswith high level of LDL cholesterol and total cholesterol. Farmers presented a high level of tryglycerides. The prevalence of obesity was higher in non farmers 51 (36.96%) than farmers 18 (17.82%). The prevalence of metabolic syndrome was 106 (44.35%) in our study population. There was not an important difference between farmers (39.60%) and non farmers (47.82%). However, the variation of metabolic syndrome according to age and sex showed a higher prevalence in young male farmers aged 25 to 45 whereas non farmers presented an increasing prevalence of metabolic syndrome according to age and the absence of metabolic syndrome between age 25 and 35. Our results showed that the cardiovascular risk appeared early in young farmers compared with non farmers suggesting a possible role of pesticides in the onset of this risk.展开更多

Verdc.) has economic importance for the producers and the traders as cash crop since it generates substantial income for households in Niger. The objective of this study was to assess eight (8) Bambara groundnut morphotype from Université André Salifou de Zinder in Niger Republic by their morphological and agronomic characters. The experiment was conducted in a randomized complete block design with three replications during the rainy season of 2020-2021. Data were collected on the Number of leaves, Plant height (cm), Growth habit (cm), Terminal leaflet length, Terminal leaflet width, Number of nodes/stem, Number of stems/plant, Number of pods/plant, Weight of 100 pods (g), Weight of 100 seeds (g), Length of seeds (mm), Width of seeds (mm), Weight of seeds/Plot (kg). There were significant differences for all characters, except Number of leaves, Terminal leaflet length, Terminal leaflet width, Length of seeds (mm) Weight of 100 pods (g), Weight of 100 seeds (g). The morphotypes UZ-VZ-04, UZ-VZ-03, UZ-VZ-06, UZ-VZ-02 and UZ-VZ-05 have demonstrated good performance for grain weight per plot and can be useful for a breeding program.展开更多

The experiments were carried out on 128 rabbits divided into 4 batches of 32 animals, reared for 8 weeks under the same conditions. Each batch was subdivided into two subgroups, one fed with a complete diet (a diet containing one of the fiber sources and served all day) and the other with the same diet separated from the fiber source (served at 9 a.m. and supplemented with the fiber source at 4 p.m.). Eight (8) experimental rations were, respectively, tested on the subgroups: complete feed Gliricidia sepium (CFG);supplemented feed Gliricidia sepium (SFG);complete feed Leucaena leucocephala (CFL);supplemented feed Leucaena leucocephala (SFL);complete feed Moringa oleifera (CFM);supplemented feed Moringa oleifera (SFM);complete feed palm nut fiber (CFF);supplemented feed palm nut fiber (SFF). In each subgroup, 4 rabbits were slaughtered at 15 weeks of age for a total of 32 rabbits. Physico-chemical parameters were evaluated on the feed and the meat. Data were analyzed using SAS 2013 software. Fiber content was similar (p > 0.05) for complete feeds. Fat content was high (p < 0.001) for the palm nuts fiber (27.34%) and the CFF feed (11.36%). Feeding rabbits with G. sepium leaves or palm nut fiber continuously increased the fat content of the meat in contrast to sequential feeding. Meat quality was also better when the fiber source was used in the feed of the rabbits in the evening.展开更多

Multi-week sampling was conducted in an urban site (industrial area) in Abidjan from April 2018 to July 2019. The mean mass concentration was 48.83 ± 15.24 μg/m<sup>3</sup> for PM<sub>2.5</sub> and 77.34 ± 10.91 μg/m<sup>3</sup> for PM<sub>10</sub>, with significant temporal variability. The average ratio of PM<sub>2.5</sub>/PM<sub>10</sub> was 0.64 ± 0.21. The concentration of BC in PM<sub>2.5</sub> and PM<sub>10</sub> was respectively 52.32 ± 7.48 μg/m<sup>3</sup> and 52.26 ± 12.07 μg/m<sup>3</sup>. Twenty-two elements: Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Rb, Sr, Zr and Pb were analysed by Energy Dispersive X-ray Fluorescence (EDXRF). Elemental composition data were modeled using principal component analysis (PCA) with varimax rotation to determine two (2) and four (4) dominant source categories contributing to PM<sub>2.5</sub> and PM<sub>10</sub> respectively. In the case of fine particles PM<sub>2.5</sub>, the possible sources were Industrial activities and non-exhaust emissions, exhaust emissions. The PM<sub>10</sub> sources were industrial activities and non-exhaust emissions, industrial processes, mineral dust, and waste combustion.展开更多

However, they are not devoid of adverse health effects on exposed operators. Therefore, we propose to assess the radiological risk of the interventional radiology team of the International Polyclinic of Indénié of Abidjan during the procedures of Embolization of uterine fibromyomas. The effective and equivalent doses to the extremities and crystals were estimated by TLD dosimeters positioned at different body areas selected on the basis of a radiological analysis of the exposure of personnel during five procedures. The analysis of fluoroscopic and record times showed variability in or an average fluoroscopy time of 32.37 min with extremes of 25.14 to 56.32 min;average record time of 0.52 min with extremes of 0.12 min to 1 min. The annual effective doses were respectively, 4.04 mSv, 3.42 mSv, 2.84 mSv;2.28 mSv, in the Radiologist (R), Operator Assistant (O2);Anesthesiologist (A2), Manipulator (M2). The annual equivalent doses to the radiologist’s predominant extremities and lenses were left index and left lens with values of 37.07 mSv and 9.46 mSv. The estimated doses in our study are reassuring from a regulatory point of view of dose limits. The results of our work have shown no significant short-term danger to the health of personnel.展开更多

The neural tube does not close properly around the 28th day of life and affects the development of the spinal column and spinal cord. Spina bifida is characterised by damage to the nervous system and will generate handicaps and damage of varying degrees: neurological motor, sensory, cognitive, genito-phincter (bladder and anorectal) deficits with consequences for the quality of life of these people. The literature describes the association between spinal dysraphism and genital prolapse. However, genital prolapse is an exceptional and rare entity in newborns. We report the observations of two newborns: the first case of a newborn born at term, at 7 days of age, who presented a prolapse of the uterine cervix in association with myelomeningocele, without any neuromuscular repercussions, and the second case of a newborn at 10 days of age, presenting with a lumbosacral spina bifida and a uterine prolapse. They benefited from conservative medical treatment characterised by manual reduction of the prolapse in both cases with a favourable evolution. In the case of spina bifida, a cure of myelomeningocele was performed surgically with simple postoperative course.展开更多

Moench), is grown as a sole crop and as a field crop in Niger. In the present study, three okra varieties from Zinder region in Niger Republic have been assessed for their agronomic performance traits. The experiment was conducted in a randomized complete block design with three replications during the dry season 2018-2019. The following characters were evaluated: emergence;germination;boutonization flowering;fructificaion;height at flowering;height at maturity;length of the petiole;diameter of leaves;diameter of plants;number of fruits;number of fruit per branch;total number of fruits;number of branch, number of leaves;length of fruits;diameter of fruits;number of arrets;weight of fruits;weight of seed, number of seeds. The collected data were subjected to analysis of variance (ANOVA) using XlStat version 7.1 and the means separated by using Turkey’s Method. Analysis of Principal components (PCA) using R software was also performed on the variables. There were significant differences for all characters except emergence, germination, diameter of plants, number of fruits, total number of fruits and diameter of fruits. The multivariate analysis by the ACP showed a grouping of the varieties in three groups. The three okra varieties have revealed good performances and could be useful for a breeding program. The study of the water needs of the varieties will be very interesting to make a better selection of the collection.展开更多

During malaria, changes in fluid volume are rather multifarious and estimating this parameter, especially in sick children is very challenging for clinicians who frequently rely on indices such as long capillary refill times, tachycardia, central venous pressure and decreased urine volume as guides. Here, we present the UHAS-MIDA, an open-source software tool that calculates the red blood cell (RBC) concentration and blood volume during malaria in children determined using a stable isotope of chromium (<sup>53</sup>Cr as the label) by gas chromatography-mass spectrometry in selective ion monitoring (GC/MS-SIM) analysis. A key component involves the determination of the compositions of the most abundant naturally occurring isotopes of Cr (<sup>50</sup>Cr, <sup>52</sup>Cr, <sup>53</sup>Cr), and converting the proportions into a 3 × 3 matrix. To estimate unknown proportions of chromium isotopic mixtures from the measured abundances of three ions, an inverse matrix was calculated. The inverse together with several inputs is then used to calculate the corrected MS ion abundances. Thus, we constructed the software tool UHAS- MIDA using HTML, CSS/Bootstrap, JavaScript, and PHP scripting languages. The tool enables the user to efficiently determine RBC concentration and fluid volume. The source code, binary packages and associated materials for UHAS-MIDA are freely available at https://github.com/bentil078/Abaye-et-al_UHASmida展开更多

This pollution is characterized by pH and conductivity parameters, concentrations average in mg/L of metals such Fe (0.731), Mn (0.345), Cr (0.070), Cu (0.014) and concentrations of nutrients known to be pollutants and toxic for living or-ganisms. These heavy metals are dangerous to the lives, the local inhabitants and also a threat to aquatic life since this water is essential for the economical town, Abidjan. According to the Manganese concentration average (0.345 mg) values that higher than WHO (0.05 mg) value, the main likely source of pollu-tants is anthropogenic, industrial and agricultural. This study also shows the use of materials and lubricants near the lagoon that pollute this water.展开更多

They frequently have comorbidities and reduced physiologic reserves, influencing treatment decisions and outcomes. Hence, a comprehensive approach is fundamental to ensure better results. The authors retrospectively evaluated the profile of 332 cases of geriatric trauma over ten years (January 2010-December 2019) at National Orthopaedic Hospital Enugu, in South-East Nigeria. The mean age of patients was 74.78 years (SD = 8.69), with females presenting at a later age than men (76.05 vs 73.69 years), p = 0.013. The commonest mechanism of injury was ground-level fall (47.59%), with proximal femoral fractures being the most common (41.27%). Only 47% of geriatric patients presented to a hospital within 24 hours following injury, and the mean duration of admission was 28 days. Approximately 77% of patients had operative care, and 68.67% expressed satisfaction with the outcome of their management. The mortality rate was 2.11%. In conclusion, most geriatric fractures require surgical intervention and education to facilitate early hospital presentation is needed.展开更多

Noise pollution has an adverse health effect to human population, when exposed for a long period. Residence in proximate communities along the north industrial area and those working in the various industries located in the area may be affected, when the noise pollution level exceed the permissible standard for human exposure. A sound level meter was used to measure the amount of noise pollution at the streets of the northern industrial area. The measurements were done during the daytime, at a time interval of 2 hours, from 08:00 am - 06:00 pm. The amount of noise pollution obtained from the study ranges from (64 - 72) dB (A), with a maximum of 72 dB (A) in Bonsmara Street, (67.4 - 75.3) dB (A), with a maximum of 75.3 dB (A) in New Castle Street, (60.5 - 81.0) dB (A), with a maximum of 72.3 dB (A) in Braham Street. (62.5 - 72.3) dB (A), with a maximum of 82.3 dB (A) in Hosea Kutako Street, (66.0 - 82.3) dB (A), with a maximum of 76.8 dB (A) in Simmentaler Street and (65.1 - 76.8) dB (A), with a maximum of 76.8 dB (A) in Dortmund Street. The variation of noise level index L10, L50, L90 and Leq, Noise Climate (NC) and Traffic Noise index (TNI) were calculated. The maximum noise pollution values obtained from the study were higher than the WHO recommended limit of 70 dB (A).展开更多

In tertiarybased nursing courses, students spend time learning in the clinical setting as they do in their classroombased studies. The purpose of this study was to explore teaching skills considered by undergraduate student nurses as effective in the clinical setting as well as qualities that make a clinical teacher effective. A descriptive design was employed using questionnaires to collect data. Respondents comprised year four undergraduate student nurses admitted through direct entry (DE) and university matriculation examination (UME) results. Using validated structured questionnaire, data were collected from 101 students who had completed their six months consolidated clinical experience on their perception of teaching skills and teacher qualities considered effective in the clinical setting. Data were analyzed using both descriptive and inferential statistics. Specifically, frequencies, percentage and standard deviation were used for descriptive analysis of scores while chi square and Mann-Whitney tests were used to test the mean differences in the teaching skills and to test whether there was a significant difference in their perception of teacher behaviours respectively at 0.05 level of significance. The result showed that having both clinical (professional) and teaching knowledge were the most important teaching skills for effective clinical teaching. Five qualities ranked by students as teacher behaviours important for effective teaching include being honest with students, motivation to teach, willingness to listen and using good communication skills, supervising students effectively and being positive role model. These factors could be considered when recruiting future clinical teachers and when planning inservice education programmes for clinical teachers to promote student learning.展开更多

The common practice has been incineration or dumping into dumpsite. The enormous heaps of these rice husks which have piled up since the 1960s now constitute nuisance. Removal of this rice husk from the environment is urgently needed because of the environmental pollution and health hazards it poses to the people and the environs. This study estimates the willingness to pay (WTP) for improved waste disposal services. Findings indicated that about 95% (152) of the households were willing to pay for removal of rice husk waste with an average amount of N957. Factors that positively affected WTP for the removal of rice husk from the environment include annual income (0.001), years of education (0.013), farm size (0.051), age (0.025) and farming experience (0.008), while household size (0.003) and distances of homes/farms from rice mill centers (RMCs) (0.001) were inversely related to WTP with the R2 value of 77%. About 90% (144) of the respondents generated rice husk with an average of 23 bags (kg). The study therefore recommends among others that through the help of extension agents, the general public should be informed on the need for waste recycling and the need for attitudinal change towards recycled product.展开更多

From Ivorian traditional origin, its popularity is increasing in Africa and production networks are developing. However, the growth of attiéké industry is still curbed by lack of technical skills of producers and irregular quality, depending on cassava variety, processing and inoculum. In the present study, a traditional inoculum and four cassava varieties (two improved local (IAC and Bonoua) and two improved sweet ones from Nigeria (Olekanga and TMS 4 (2) 1425)) were used for producing attiéké Ebrié. For the sensorial evaluation of prepared attiéké, qualitative sensory profiling was used. The sensory quality descriptors where quantitatively measured by a trained sensory panel. With this method the most important quality criteria of attiéké were judged. These quality criteria were selected with the aid of surveys on its production and consumption. The relationships between sensory attributes of the four attiéké prepared of the different cassava varieties and biochemical characteristics were studied. Sensory analysis revealed that the four attiéké were cream-colored products with sweet and/or sour tastes, made of cohesive and well-formed grains of different sizes, with an odor of fermentation specific to attiéké and showing a firm texture. The differences between sensory profiles of the four attiéké produced from four cassava varieties (12 months growth) concern only some descriptors of quality. Pearson correlation coefficients between physicochemical descriptors of quality showed that biochemical parameters may help predict organoleptic characteristics of attiéké Ebrié (pH-size of grains: r = 0.99;pH-acidity: r = ?0.92;acidity-rounded grains: r = ?0.98: starch-cohesion between grains: r = ?0.96;starch-sweet: r = ?0.95;starch-granulous: r = 0.97, total sugar-yellow color: r = 0.96;total sugar-aroma of attiéké: r = 0.96;reducing sugar-odor of attiéké: r = 0.95;cyanide-fibrous: r = 0.95).展开更多
文摘Our study was carried out to determine the phenotypic characterization antimicrobial susceptibility of Proteus mirabilis from fish in FCT, Abuja using isolation, selective plating, preliminary observation, complete biochemical method and antimicrobial susceptibility testing. The biochemical tests conducted includes include Citrate Utilization test, Triple Sugar Iron test, Urea test, Methyl Red test, Indole test, and Voges Proskauer test. The isolates were confirmed by Microbact<sup>TM</sup>GNB24E identification kit (Oxiod, UK). A total of 400 fish samples were bought in the market from three area council of the FCT. The result of the study showed overall prevalence rate of (13) 3.25% of Proteus mirabilis isolates. Distribution based on Area councils showed that AMAC had higher prevalence rate of 4.81%, while Bwari had 2.99% and Gwagwalada with 2.57% prevalence. All isolates were subjected to antimicrobial susceptibility testing using the modified single disc diffusion method. From the antimicrobial susceptibility testing done it was discovered that Proteus mirabilis are resistant to Amoxyclav (100%), Erythromycin (92.3%), Tetracycline (92.3%) and Ceftriaxone (23.1%). However, the isolates were susceptible to Ofloxacin (100%), Netillin (92.3%), Levofloxacin (92.3%), Ceftazidime (76.9%), Co-trimoxazole (69.2%) and Gentamicin (61.5%). Since Proteus mirabilis sources of zoonotic diseases and can potentially be dangerous to humans and other animals, our research was able to isolate it from fresh water fish sold in the Federal Capital Territory. This makes public health awareness of the risks associated with Proteus mirabilis in Nigeria necessary.
文摘Background: One of the key drivers for the emergence and spread of antimicrobial resistance (AMR) is non-prudent antibiotic use, which results in selection pressure toward relevant bacteria. Pharmacy staffs have pivotal roles in facilitating the prudent use of antibiotics through antimicrobial stewardship programs. Due to limited information in Benin, this study assessed the knowledge and attitudes of pharmacy staffs on antibiotic use and resistance. Materials and Methods: This cross-sectional study was conducted among 159 pharmacy staffs using a structured questionnaire from August 2018 to December 2018 in Benin. Data analysis was done by using Stata version 13.0. Results: Of the 159 participants, 54.8% knew the definition of antibiotic therapy and 66.9% knew the definition of probabilistic antibiotic therapy. The majority (88.1%) of the participants thought that the choice of antibiotics was made according to the pathology, while 60.4% thought that it depended on the pathology and the germ involved. 49.02% of dispensers in pharmacies stated that half of the patients had requested treatment without providing a prescription at the pharmacy. The top three antibiotics that were dispensed without a prescription include amoxicillin (98.1%), cloxacillin (76.7%) and metronidazole (57.2%), all from the Access group of antibiotics. Conclusion: These results underscore the need for educational and training interventions targeting specific professional groups. There is an urgent need for regulatory measures and public awareness through improved antimicrobial stewardship to limit this practice.
文摘The heavy use of chemicals, pesticides, cosmetics and plastic packaging coincides with a resurgence of cardiovascular disease, in particular hypertension, which is affecting younger and younger populations. The aim of this study was to analyze the cardiovascular risk factors in hypertensive farmers compared with hypertensive non farmers. This was a prospective case-control study that included 239 hypertensive farmers and non farmers aged 25 to 65 with blood pressure ≥ 140 mmHg and 90 mmHg. Hypertensive farmers (101) represented 42.25% of the population versus hypertensive non farmers (138) 57.74%. The median ages were 47 ± 11.3 years for farmers and 51.45 ± 9.77 years for non farmers. Biochemical analysisand screening for major cardiovascular disease risk factors such as metabolic syndrome were performed. Metabolic syndrome was defined according to the new definition of the International Diabetes Federation. Our results revealed higher blood glucose levels in farmers (47.77%) than in non farmers (27.20%) (p = 0.0132). Dyslipidemia was more frequent in non farmerswith high level of LDL cholesterol and total cholesterol. Farmers presented a high level of tryglycerides. The prevalence of obesity was higher in non farmers 51 (36.96%) than farmers 18 (17.82%). The prevalence of metabolic syndrome was 106 (44.35%) in our study population. There was not an important difference between farmers (39.60%) and non farmers (47.82%). However, the variation of metabolic syndrome according to age and sex showed a higher prevalence in young male farmers aged 25 to 45 whereas non farmers presented an increasing prevalence of metabolic syndrome according to age and the absence of metabolic syndrome between age 25 and 35. Our results showed that the cardiovascular risk appeared early in young farmers compared with non farmers suggesting a possible role of pesticides in the onset of this risk.
文摘Bambara groundnut (Vigna subterranea (L.) Verdc.) has economic importance for the producers and the traders as cash crop since it generates substantial income for households in Niger. The objective of this study was to assess eight (8) Bambara groundnut morphotype from Université André Salifou de Zinder in Niger Republic by their morphological and agronomic characters. The experiment was conducted in a randomized complete block design with three replications during the rainy season of 2020-2021. Data were collected on the Number of leaves, Plant height (cm), Growth habit (cm), Terminal leaflet length, Terminal leaflet width, Number of nodes/stem, Number of stems/plant, Number of pods/plant, Weight of 100 pods (g), Weight of 100 seeds (g), Length of seeds (mm), Width of seeds (mm), Weight of seeds/Plot (kg). There were significant differences for all characters, except Number of leaves, Terminal leaflet length, Terminal leaflet width, Length of seeds (mm) Weight of 100 pods (g), Weight of 100 seeds (g). The morphotypes UZ-VZ-04, UZ-VZ-03, UZ-VZ-06, UZ-VZ-02 and UZ-VZ-05 have demonstrated good performance for grain weight per plot and can be useful for a breeding program.
文摘This study was conducted to valorize four sources of fiber (Gliricidia sepium, Leucaena leucocephala, Moringa oleifera and palm nut fibers) in animal production. The experiments were carried out on 128 rabbits divided into 4 batches of 32 animals, reared for 8 weeks under the same conditions. Each batch was subdivided into two subgroups, one fed with a complete diet (a diet containing one of the fiber sources and served all day) and the other with the same diet separated from the fiber source (served at 9 a.m. and supplemented with the fiber source at 4 p.m.). Eight (8) experimental rations were, respectively, tested on the subgroups: complete feed Gliricidia sepium (CFG);supplemented feed Gliricidia sepium (SFG);complete feed Leucaena leucocephala (CFL);supplemented feed Leucaena leucocephala (SFL);complete feed Moringa oleifera (CFM);supplemented feed Moringa oleifera (SFM);complete feed palm nut fiber (CFF);supplemented feed palm nut fiber (SFF). In each subgroup, 4 rabbits were slaughtered at 15 weeks of age for a total of 32 rabbits. Physico-chemical parameters were evaluated on the feed and the meat. Data were analyzed using SAS 2013 software. Fiber content was similar (p > 0.05) for complete feeds. Fat content was high (p < 0.001) for the palm nuts fiber (27.34%) and the CFF feed (11.36%). Feeding rabbits with G. sepium leaves or palm nut fiber continuously increased the fat content of the meat in contrast to sequential feeding. Meat quality was also better when the fiber source was used in the feed of the rabbits in the evening.
文摘Epilepsy is a neurological disease characterized by excessive and abnormal hyper-synchrony of electrical discharges of the brain and a predisposition to generate epileptic seizures resulting in a broad spectrum of neurobiological insults,imposing psychological,cognitive,social and also economic burdens to the sufferer.Voltage-gated sodium channels(VGSCs)are essential for the generation and propagation of action potentials throughout the central nervous system.Dysfunction of these channels has been implicated in the pathogenesis of epilepsy.VGSC inhibitors have been demonstrated to act as anticonvulsants to suppress the abnormal neuronal firing underlying epileptic seizures,and are used for the management and treatment of both genetic-idiopathic and acquired epilepsies.We discuss the forms of idiopathic and acquired epilepsies caused by VGSC mutations and the therapeutic efficacy of VGSC blockers in idiopathic,acquired and pharmacoresistant forms of epilepsy in this review.We conclude that there is a need for better alternative therapies that can be used alone or in combination with VGSC inhibitors in the management of epilepsies.The current anti-seizure medications(ASMs)especially for pharmacoresistant epilepsies and some other types of epilepsy have not yielded expected therapeutic efficacy partly because they do not show subtype-selectivity in blocking sodium channels while also bringing side effects.Therefore,there is a need to develop novel drug cocktails with enhanced selectivity for specific VGSC isoforms,to achieve better treatment of pharmacoresistant epilepsies and other types of epileptic seizures.
文摘This paper describes the evaluation of trace element composition of atmospheric aerosol particles (PM<sub>2.5</sub> and PM<sub>10</sub>) and their influence on air quality in the largest industrial area of Abidjan city, C?te d’Ivoire. Multi-week sampling was conducted in an urban site (industrial area) in Abidjan from April 2018 to July 2019. The mean mass concentration was 48.83 ± 15.24 μg/m<sup>3</sup> for PM<sub>2.5</sub> and 77.34 ± 10.91 μg/m<sup>3</sup> for PM<sub>10</sub>, with significant temporal variability. The average ratio of PM<sub>2.5</sub>/PM<sub>10</sub> was 0.64 ± 0.21. The concentration of BC in PM<sub>2.5</sub> and PM<sub>10</sub> was respectively 52.32 ± 7.48 μg/m<sup>3</sup> and 52.26 ± 12.07 μg/m<sup>3</sup>. Twenty-two elements: Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Rb, Sr, Zr and Pb were analysed by Energy Dispersive X-ray Fluorescence (EDXRF). Elemental composition data were modeled using principal component analysis (PCA) with varimax rotation to determine two (2) and four (4) dominant source categories contributing to PM<sub>2.5</sub> and PM<sub>10</sub> respectively. In the case of fine particles PM<sub>2.5</sub>, the possible sources were Industrial activities and non-exhaust emissions, exhaust emissions. The PM<sub>10</sub> sources were industrial activities and non-exhaust emissions, industrial processes, mineral dust, and waste combustion.
文摘Ionizing radiation is widely used in medical practice for both diagnostic and therapeutic purposes. However, they are not devoid of adverse health effects on exposed operators. Therefore, we propose to assess the radiological risk of the interventional radiology team of the International Polyclinic of Indénié of Abidjan during the procedures of Embolization of uterine fibromyomas. The effective and equivalent doses to the extremities and crystals were estimated by TLD dosimeters positioned at different body areas selected on the basis of a radiological analysis of the exposure of personnel during five procedures. The analysis of fluoroscopic and record times showed variability in or an average fluoroscopy time of 32.37 min with extremes of 25.14 to 56.32 min;average record time of 0.52 min with extremes of 0.12 min to 1 min. The annual effective doses were respectively, 4.04 mSv, 3.42 mSv, 2.84 mSv;2.28 mSv, in the Radiologist (R), Operator Assistant (O2);Anesthesiologist (A2), Manipulator (M2). The annual equivalent doses to the radiologist’s predominant extremities and lenses were left index and left lens with values of 37.07 mSv and 9.46 mSv. The estimated doses in our study are reassuring from a regulatory point of view of dose limits. The results of our work have shown no significant short-term danger to the health of personnel.
文摘Spina bifida, or spinal dysraphism, is a malformative pathology related to an anomaly in the development of the nervous system, occurring during embryogenesis. The neural tube does not close properly around the 28th day of life and affects the development of the spinal column and spinal cord. Spina bifida is characterised by damage to the nervous system and will generate handicaps and damage of varying degrees: neurological motor, sensory, cognitive, genito-phincter (bladder and anorectal) deficits with consequences for the quality of life of these people. The literature describes the association between spinal dysraphism and genital prolapse. However, genital prolapse is an exceptional and rare entity in newborns. We report the observations of two newborns: the first case of a newborn born at term, at 7 days of age, who presented a prolapse of the uterine cervix in association with myelomeningocele, without any neuromuscular repercussions, and the second case of a newborn at 10 days of age, presenting with a lumbosacral spina bifida and a uterine prolapse. They benefited from conservative medical treatment characterised by manual reduction of the prolapse in both cases with a favourable evolution. In the case of spina bifida, a cure of myelomeningocele was performed surgically with simple postoperative course.
文摘Okra, (Abelmoschus esculentus (L.) Moench), is grown as a sole crop and as a field crop in Niger. In the present study, three okra varieties from Zinder region in Niger Republic have been assessed for their agronomic performance traits. The experiment was conducted in a randomized complete block design with three replications during the dry season 2018-2019. The following characters were evaluated: emergence;germination;boutonization flowering;fructificaion;height at flowering;height at maturity;length of the petiole;diameter of leaves;diameter of plants;number of fruits;number of fruit per branch;total number of fruits;number of branch, number of leaves;length of fruits;diameter of fruits;number of arrets;weight of fruits;weight of seed, number of seeds. The collected data were subjected to analysis of variance (ANOVA) using XlStat version 7.1 and the means separated by using Turkey’s Method. Analysis of Principal components (PCA) using R software was also performed on the variables. There were significant differences for all characters except emergence, germination, diameter of plants, number of fruits, total number of fruits and diameter of fruits. The multivariate analysis by the ACP showed a grouping of the varieties in three groups. The three okra varieties have revealed good performances and could be useful for a breeding program. The study of the water needs of the varieties will be very interesting to make a better selection of the collection.
文摘Clinical assessment of fluid volume status in children during malaria can be taxing and often inaccurate. During malaria, changes in fluid volume are rather multifarious and estimating this parameter, especially in sick children is very challenging for clinicians who frequently rely on indices such as long capillary refill times, tachycardia, central venous pressure and decreased urine volume as guides. Here, we present the UHAS-MIDA, an open-source software tool that calculates the red blood cell (RBC) concentration and blood volume during malaria in children determined using a stable isotope of chromium (<sup>53</sup>Cr as the label) by gas chromatography-mass spectrometry in selective ion monitoring (GC/MS-SIM) analysis. A key component involves the determination of the compositions of the most abundant naturally occurring isotopes of Cr (<sup>50</sup>Cr, <sup>52</sup>Cr, <sup>53</sup>Cr), and converting the proportions into a 3 × 3 matrix. To estimate unknown proportions of chromium isotopic mixtures from the measured abundances of three ions, an inverse matrix was calculated. The inverse together with several inputs is then used to calculate the corrected MS ion abundances. Thus, we constructed the software tool UHAS- MIDA using HTML, CSS/Bootstrap, JavaScript, and PHP scripting languages. The tool enables the user to efficiently determine RBC concentration and fluid volume. The source code, binary packages and associated materials for UHAS-MIDA are freely available at https://github.com/bentil078/Abaye-et-al_UHASmida
文摘Eight water bottles from Ebrie lagoon with pollution potency were studied using nuclear chemistry technique and Energy dispersive X-ray fluorescence. This pollution is characterized by pH and conductivity parameters, concentrations average in mg/L of metals such Fe (0.731), Mn (0.345), Cr (0.070), Cu (0.014) and concentrations of nutrients known to be pollutants and toxic for living or-ganisms. These heavy metals are dangerous to the lives, the local inhabitants and also a threat to aquatic life since this water is essential for the economical town, Abidjan. According to the Manganese concentration average (0.345 mg) values that higher than WHO (0.05 mg) value, the main likely source of pollu-tants is anthropogenic, industrial and agricultural. This study also shows the use of materials and lubricants near the lagoon that pollute this water.
文摘Geriatric trauma patients require special consideration. They frequently have comorbidities and reduced physiologic reserves, influencing treatment decisions and outcomes. Hence, a comprehensive approach is fundamental to ensure better results. The authors retrospectively evaluated the profile of 332 cases of geriatric trauma over ten years (January 2010-December 2019) at National Orthopaedic Hospital Enugu, in South-East Nigeria. The mean age of patients was 74.78 years (SD = 8.69), with females presenting at a later age than men (76.05 vs 73.69 years), p = 0.013. The commonest mechanism of injury was ground-level fall (47.59%), with proximal femoral fractures being the most common (41.27%). Only 47% of geriatric patients presented to a hospital within 24 hours following injury, and the mean duration of admission was 28 days. Approximately 77% of patients had operative care, and 68.67% expressed satisfaction with the outcome of their management. The mortality rate was 2.11%. In conclusion, most geriatric fractures require surgical intervention and education to facilitate early hospital presentation is needed.

文摘The increase in industrial activities and vehicular movement along the northern industrial area of Windhoek has vastly increased the amount of traffic noise and other noise pollution in the area. Noise pollution has an adverse health effect to human population, when exposed for a long period. Residence in proximate communities along the north industrial area and those working in the various industries located in the area may be affected, when the noise pollution level exceed the permissible standard for human exposure. A sound level meter was used to measure the amount of noise pollution at the streets of the northern industrial area. The measurements were done during the daytime, at a time interval of 2 hours, from 08:00 am - 06:00 pm. The amount of noise pollution obtained from the study ranges from (64 - 72) dB (A), with a maximum of 72 dB (A) in Bonsmara Street, (67.4 - 75.3) dB (A), with a maximum of 75.3 dB (A) in New Castle Street, (60.5 - 81.0) dB (A), with a maximum of 72.3 dB (A) in Braham Street. (62.5 - 72.3) dB (A), with a maximum of 82.3 dB (A) in Hosea Kutako Street, (66.0 - 82.3) dB (A), with a maximum of 76.8 dB (A) in Simmentaler Street and (65.1 - 76.8) dB (A), with a maximum of 76.8 dB (A) in Dortmund Street. The variation of noise level index L10, L50, L90 and Leq, Noise Climate (NC) and Traffic Noise index (TNI) were calculated. The maximum noise pollution values obtained from the study were higher than the WHO recommended limit of 70 dB (A).
文摘Learning in the clinical environment is an integral part of nursing education programme. In tertiarybased nursing courses, students spend time learning in the clinical setting as they do in their classroombased studies. The purpose of this study was to explore teaching skills considered by undergraduate student nurses as effective in the clinical setting as well as qualities that make a clinical teacher effective. A descriptive design was employed using questionnaires to collect data. Respondents comprised year four undergraduate student nurses admitted through direct entry (DE) and university matriculation examination (UME) results. Using validated structured questionnaire, data were collected from 101 students who had completed their six months consolidated clinical experience on their perception of teaching skills and teacher qualities considered effective in the clinical setting. Data were analyzed using both descriptive and inferential statistics. Specifically, frequencies, percentage and standard deviation were used for descriptive analysis of scores while chi square and Mann-Whitney tests were used to test the mean differences in the teaching skills and to test whether there was a significant difference in their perception of teacher behaviours respectively at 0.05 level of significance. The result showed that having both clinical (professional) and teaching knowledge were the most important teaching skills for effective clinical teaching. Five qualities ranked by students as teacher behaviours important for effective teaching include being honest with students, motivation to teach, willingness to listen and using good communication skills, supervising students effectively and being positive role model. These factors could be considered when recruiting future clinical teachers and when planning inservice education programmes for clinical teachers to promote student learning.
文摘Increasing generation of rice husk requires better quality disposal options in Ebonyi State, Nigeria. The common practice has been incineration or dumping into dumpsite. The enormous heaps of these rice husks which have piled up since the 1960s now constitute nuisance. Removal of this rice husk from the environment is urgently needed because of the environmental pollution and health hazards it poses to the people and the environs. This study estimates the willingness to pay (WTP) for improved waste disposal services. Findings indicated that about 95% (152) of the households were willing to pay for removal of rice husk waste with an average amount of N957. Factors that positively affected WTP for the removal of rice husk from the environment include annual income (0.001), years of education (0.013), farm size (0.051), age (0.025) and farming experience (0.008), while household size (0.003) and distances of homes/farms from rice mill centers (RMCs) (0.001) were inversely related to WTP with the R2 value of 77%. About 90% (144) of the respondents generated rice husk with an average of 23 bags (kg). The study therefore recommends among others that through the help of extension agents, the general public should be informed on the need for waste recycling and the need for attitudinal change towards recycled product.
文摘Background:Globally,there is a high demand for nurses,resulting in migration from low‑to high‑income countries.The emigration of nurses is the act of leaving one's own country to settle permanently in another country,leading to a shortage in the number of nurses in their home countries.Consequently,this study aims to assess the impact of the emigration of nurses on the health‑care delivery system in Nigeria.Materials and Methods:A descriptive cross‑sectional survey was conducted with a stratified sampling technique to select 270 nurses from three selected hospitals in Benin‑city Edo state.A self‑structured questionnaire with open and Likert scale questions were used as an instrument to assess the Impact of the Emigration of nurses on the Health Care Delivery System.Data collected were analyzed using tables,percentages,means,standard deviation and t‑test.Results:The result showed a mean score of 1.59±0.92 impacts of the emigration of nurses on health‑care delivery system and identified how to reduce it.The study also showed that there is no significant difference between gender and reason for emigration among nurses(t=3.84,P≤0.001).Conclusion:The emigration of nurses is severely affecting the health care delivery system in the country.Recently,the Nursing and Midwifery Council of Nigeria gave the directive for training schools to increase their training capacity and number of students’intake to cushion the effect,and this study shows that this palliative can only be a short time measure,and however will encourage more nurses traveling abroad on the long run.Therefore,the hospital managers and government should provide a conducive working environment,better remuneration,attractive retirement benefit,and other incentives as a push in factor for nurses to stay back in their home countries.
文摘Attiéké is fermented cassava semolina steamed and consumed with proteins and vegetables. From Ivorian traditional origin, its popularity is increasing in Africa and production networks are developing. However, the growth of attiéké industry is still curbed by lack of technical skills of producers and irregular quality, depending on cassava variety, processing and inoculum. In the present study, a traditional inoculum and four cassava varieties (two improved local (IAC and Bonoua) and two improved sweet ones from Nigeria (Olekanga and TMS 4 (2) 1425)) were used for producing attiéké Ebrié. For the sensorial evaluation of prepared attiéké, qualitative sensory profiling was used. The sensory quality descriptors where quantitatively measured by a trained sensory panel. With this method the most important quality criteria of attiéké were judged. These quality criteria were selected with the aid of surveys on its production and consumption. The relationships between sensory attributes of the four attiéké prepared of the different cassava varieties and biochemical characteristics were studied. Sensory analysis revealed that the four attiéké were cream-colored products with sweet and/or sour tastes, made of cohesive and well-formed grains of different sizes, with an odor of fermentation specific to attiéké and showing a firm texture. The differences between sensory profiles of the four attiéké produced from four cassava varieties (12 months growth) concern only some descriptors of quality. Pearson correlation coefficients between physicochemical descriptors of quality showed that biochemical parameters may help predict organoleptic characteristics of attiéké Ebrié (pH-size of grains: r = 0.99;pH-acidity: r = ?0.92;acidity-rounded grains: r = ?0.98: starch-cohesion between grains: r = ?0.96;starch-sweet: r = ?0.95;starch-granulous: r = 0.97, total sugar-yellow color: r = 0.96;total sugar-aroma of attiéké: r = 0.96;reducing sugar-odor of attiéké: r = 0.95;cyanide-fibrous: r = 0.95).
