Background: Cardiac involvement and the consequences of inflammation induced by SARS-CoV2 infection could have catastrophic long-term consequences. Left ventricular mechanics could identify a specific pattern of myocardial fiber damage in patients infected with COVID-19. To our knowledge there are no publications referring to the global description of ventricular mechanics in patients with COVID-19. Objective: To describe left ventricular mechanics in hospitalized patients with COVID-19. Methods: In this cross-sectional study, we included 40 hospitalized patients with confirmed diagnostic of COVID-19, from April 11, 2020, to September 6, 2020. Demographic and laboratory data, clinical and echocardiographic characteristics were collected, as well as events during hospitalization. Left ventricular deformation was analyzed and reported. Results: Subclinical dysfunction was observed in 82.5% (left ventricular longitudinal strain [LVGLS] -17.05% and global circumferential strain [GCS] -18.6%) of the patients, likewise, the mean twist and apical rotation were preserved, and even increased as part of the compensating mechanism to maintain the ejection fraction. Conclusion: In patients hospitalized with COVID-19, despite having a normal left ventricular ejection fraction, subclinical myocardial damage was found, manifested by a decrease in Global Longitudinal Strain (GLS) and Global Circumferential Strain (GCS). This behavior is similar to that of cardiomyopathies in the early stage of the disease, and given the pathophysiological mechanisms involved in the disease, its long-term consequences should be monitored and evaluated.

Obesity is a CVD risk factor that can be modulated for massive reduction in morbi-mortality. Traditional indices measuring it have been inconsistent and the most commonly used;BmI has proved inappropriate for Africans, not attending specifically to body fat and its distribution. With the consensus that intra-abdominal fat is the most critical for cardio-metabolic diseases, various attempts were made to measure it for risk estimation. These however require costly equipments not easily amenable for population studies. The abdominometer conceptualized by BNO has shown promise in isolated cases. This pilot study was undertaken in this restricted population to compare its utility with existing anthropometric measures of cardiovascular disease.

Journal of Building Construction and Planning Research 2018年第4期6卷 251-266页

作者： K. m. Odunfa C. J. Nnakwe V. O. Odunfa mechanical Engineering Department University of Ibadan Ibadan Nigeria Estate management Department The Polytechnic Ibadan Ibadan Nigeria

Energy consumption in both residential and public buildings has been established globally as been significantly high. The need to incorporate energy efficiency in building therefore becomes imperative in order to minimize the consumption level. This work therefore examines the effect of building orientation coupled with different building material composition on energy efficiency in building within major Nigeria climatic zones. The methodology adopted in this study entails carrying out a load survey and thereby calculating the cooling load required to condition the building space in two selected different orientations within the major Nigerian climatic zones. The standard cooling load equations were utilized in the evaluation of the various cooling loads. The selected locations considered within major Nigerian climatic zones are Ibadan in the South West, jos in the middle belt and maiduguri in the North East. The cooling load results obtained for the two different orientations are as follows;151.45 kW and 163.17 kW for Ibadan, maiduguri: 164 kW and 175.78 kW, and 131.77 kW, 143.4 kW for jos. The first orientation being North/South longitudinal placement of the building while the second orientation is East/West longitudinal placement respectively. The study established that the second orientation generated more cooling load. It is therefore concluded that the first orientation which is the North/South longitudinal placement of the building is best recommended. It also established the dependence of cooling load on the climatic condition of the building’s location. Both building material compositions coupled with its orientation and climatic condition therefore play major significant role on the energy consumption in a building space.

Testing for Human Immunodeficiency Virus (HIV), widely distributed in sub-Saharan Africa since it is mainly invasive but, could be non-invasive and quick also, reducing waiting time especially when required for presurgical procedures. This study determined the HIV status of patients using Urine screening test method and to compare its performance to blood-based testing methods. The routine pre and post-test counselling for HIV screening were done for all provider-initiated HIV testing using blood-based screening methods. Due to the cost and unavailability of enough urine testing kits, only patients who tested positive for HIV with blood-based methods and were scheduled for surgery or a surgical procedure were enrolled in the study. Informed consent was obtained. Paired urine and blood samples were collected at the same visit into clean universal bottles and analyzed immediately. A colloidal gold enhanced rapid immuno-chromatographic assay (Alliance Biomedical) kit for the rapid qualitative detection of antibodies to Human Immunodeficiency Virus (HIV) I and II in urine were used in comparison to the standard HIV testing of ante-cubital venous blood collected in EDTA vacutainer and analyzed using Determine (T) HIV 1 and 2 in vitro qualitative immunoassay strip, UNI GOLD rapid test kit and the Chembio HIV 1/2 STAT PAK assay strip. A total of 7568 patients were tested for routine provider-initiated HIV testing, 521 tested HIV positive. There were 105 (20.15%) males and 416 (79.85%) females, age ranged from 15 years to >80 years. most of the surgeries performed were Caesarian section 93 (37%), Hernia 55 (22%), Lumps 48 (19%), Acute appendicitis 33 (13%), Uterine fibroids 10 (4%), Ruptured ectopic pregnancy 2 (1%) and others (Intestinal obstruction, Postoperative adhesions, Ingrown toe nails, Breast abscess, Hemorrhoids, Anal fissures etc.) 10 (4%).

Journal of Environmental Protection 2018年第5期9卷 516-524页

作者： E. G. Ibrahim N. Yakubu L. Nnamonu J. m. Yakubu Dept. of Pure and Applied Chemistry Plateau State University Bokkos Jos Plateau Stae Nigeria Demonstration Secondary School College of Education Akwanga Nasarawa State Nigeria Dept. of Chemistry and Agrochemical Technology University of Agriculture Ma-kurdi Benue State Nigeria Dept. of microbiology Federal University Wukari Wukari Nigeria

Three green leafy vegetable samples of pumpkin leaves, spinach leaves, and sorrel leaves were collected from three different locations in a farm in Akwanga and were tested for the presence of organophosphorus (OP) compounds. The concentrations of all the pesticide residues in the vegetable samples were determined using gas chromatography with mass spectrometry (GC-mS). The organophosphorus pesticides detected include carbaryl (0.052 mg/kg) in pumpkin, this is below European maximum residues limit (EU mRL) of 0.1 mg/kg, Dimethoate was found in pumpkin (0.165 mg/kg), spinach (0.103 mg/kg) and sorrel (0.250 mg/kg) all above the EU mRL of 0.05 mg/kg. Dichlofenthion was detected in pumpkin (0.308 mg/kg), pirimiphos methyl was detected in pumpkin and spinach (0.428 mg/kg and 0.149 mg/kg respectively), all these were below the EU mRL of 0.5 mg/kg. Chlorpyrifos was found in spinach (0.230 mg/kg) and sorrel (0.192 mg/kg) only spinach was above the EU mRL of 0.2 mg/kg. The pesticide residue Bromophosethyl was detected in all vegetables, pumpkin leaves (0.501 mg/kg), sorrel (1.571 mg/kg) and spinach (7.981 mg/kg) all above the EU mRL of 0.5 mg/kg. The remaining pesticides detected were all below their EU mRL value;these are Ethion found in spinach (0.167 mg/kg), methyl Parathion in spinach (0.103 mg/kg) and sorrel (0.335 mg/kg). The levels of some of the organophosphorus pesticide residues found in vegetables were above the maximum residue limits (mRLs) set by the European Union. This calls for laws to regulate the use and circulation of such chemicals. Based on the observation made in these studies, it is proposed that more extensive monitoring investigation covering all vegetables part in Akwanga Nasarawa state be carried out to find the exact position of pesticide residues.

Fish, as one of the fishery resources, is an important constituent of the diet of the Amazon population, as it is the source of several nutritional components. The present work aimed to characterize the centesimal composition of Plagioscion squamosissimus fillet (n = 10) and macrobrachium amazonicum meat (n = 82), species acquired in the estuarine region of the state of Amapá, Brazil. Carcass yield, as well as protein, water content, lipids and ashes was determined according to the methodologies proposed by the Adolf Lutz Institute, as well as carbohydrate and caloric determinations. The analyses were performed in triplicate per sample. After comparing with the literature, it was possible to conclude that P. squamosissimus presented a fillet yield of 31.11%± 0.61%, high protein content (15.99 ± 1.26 g/100 g) and humidity (79.40 ± 1.10 g/100 g), moderate contents of mineral residues (1.10 ± 0.07 g/100 g) and carbohydrates (0.96 ± 0.90 g/100 g), low lipid contents (2.29 ± 0.65 g/100 g), as well as low caloric values (385,018.12 J/100 g) and m. amazonicum a meat yield of 44.12%± 8.34%, high levels of protein (22.81 ± 1.72 g/100 g), carbohydrates (1.92 ± 1.61 g/100 g) and mineral residues (1.76 ± 0.78 g/100 g), moderate water content (73.38 ± 0.78 g/100 g), low lipid levels (0.43 ± 0.08 g/100 g), as well as low caloric values (440,786.3 J/100 g). The results obtained in this work can serve as a subsidy in nutritional diets for humans, thus allowing an adequate dietary use of these species.
