COVID-19 vaccines: the dilemma when thinking as a patient

What is the truth about the conspiracy theory of the COVID-19 microchip vaccine? The outbreak of the COVID-19 witnessed a vicious race of pharmaceutical firms to develop a vaccine that ends this disaster. Claims were forwarded that some firms funded by well-known foundations are in the process of developing such a vaccine so people wide world can be tracked. Such claims may have been based on Mr. Bill Gate’s announcement in an interview that through vaccination "we will have some digital certificates" which would be used to show who had recovered, been tested and ultimately who received a vaccine but he made no mention of microchips.  The conspiracy theory is spreading around the world and its supporters are on the increase among the public as well as many healthcare professionals. The spread of the virus has been attributed to the introduction of 5G technology and many religious leaders attributed the crisis to punishment from God to the spread of local wars and mass killing, torturing and killing of Muslims in China and Myanmar gay and lesbian movement and marriages

Copper, Nickel and Manganese Residues in Tissues and Organs of Rabbits Dosed with Edible Clay

The study examined the kinetics of Copper (Cu), Nickel (Ni) and Manganese (Mn) in tissues and organs of rabbits treated with edible clay from Enyigba, Ebonyi state Nigeria. Clay samples were obtained from Enyigba mine. Fifty four of the sampled rabbits were grouped into 3: group 1 and group 2 were administered with 2000 mg/kg and 4000 mg/kg of edible clay respectively while group 3 served as control. Concentrations of these metals were detected in the brain, heart, kidney, liver, lungs, skeletal muscle and blood of each of the rabbits using atomic absorption spectroscopy (AAS). One - way ANOVA was used in analyzing the concentrations with significant results (p < 0.05) recorded. The study results showed that while Cu concentrations were predominant in the liver (15.33±1.18 µg/g), kidney (8.25±1.18 µg/g) and heart (9.43±2.36 µg/g) of 2000 mg/kg treated rabbits on day 1 post-treatment, Ni concentrations were the highest among the three elements especially in the blood (221.59±17.05 µg/g) and skeletal muscle (153.41±19.68 µg/g) of 2000 mg/kg treated rabbits on day 1 post-treatment. Concentrations of Mn were mostly detected in the liver (13.99±4.85 µg/g) of 2000 mg/kg treated rabbits on day 1 post-treatment. Most of the concentration values increased in 4000 mg/kg treated rabbits on day 1 post-treatment. Elimination constants as well as half-life eliminations of the metals studied showed that absorbed elements were still present in most organs and tissues of treated rabbits. The study recommends research for possible microbial toxins that may be found in the edible clay studied

Relationship Between the 6-minute Walk Test and Correlates of Type 2 Diabetes: Indication for caution in exercise prescription

Physical exercise is adjudged effective in the prevention and co-management of Type 2 diabetes (T2D). However, because of the different levels of exercise capacity; it must be prescribed with caution based on the individual’s peculiarities. The link between the 6-minute walk test and some correlates of T2D was investigated. This cross-sectional study of 58 consenting patients with T2D was conducted at the diabetes clinic of a secondary health centre in Kano, Nigeria. The measurements included the 6-Minute Walk Distance (6MWD) for exercise capacity and the T2D correlates including age, body mass index, waist circumference and waist-hip ratio. The relationships between the parameters were determined using the Pearson’s correlation coefficient at a significance level of 0.05. The participants consisted of 36 males (62.1%) and 22 females (37.9%). The mean 6MWD for males was 302 ± 33.28 meters and was shorter in women. The 6MWD correlated significantly (P < 0.05) with each of age [r = -0.78 (males), -0.62 (females)], waist circumference [r = -0.82 (males), -0.77 (females)] and body mass index [r = -0.66 (males), -0.74 (females)], while the waist hip ratio correlated significantly with the 6MWD only in the male participants (r = -0.59). Low exercise capacity in patients with T2D was associated with higher age and adiposity. Prescription of physical exercise to patients with T2D who present with one or a combination of these variables should be done with care in order not to exceed safe limits. KEY WORDS: type 2 diabetes, physical exercise, age, body mass index, waist circumference and waist-hip rati

Sensitivity of extended-spectrum β-lactamases producing Enterobacteriaceae isolates to Annona squamosa extracts

Powdered leaves of Annona squamosa (L.) were extracted with ethanol and methanol using percolation method. The extracts were tested for antimicrobial activity against clinical isolates of confirmed extended spectrum β-lactamase producing Escherichia coli, Klebsiella pneumoniae and Proteus specie using disc diffusion method. The extracts were further subjected to phytochemical screening for the presence of secondary metabolites. Sensitivity test results showed that methanol extract of the plant was only active on E. coli at 30 μg/disc concentration with 7mm zone of inhibition but inactive against P. specie even at 60 μg/disc concentration. Ethanol extract of the plant was active against all isolates only at 60 μg/disc concentration with P. specie forming slightly wider zone of inhibition (8mm) and the remaining isolates having 7mm zone diameter. The results of phytochemical screening indicated the presence of reducing sugars, saponins and steroids in either or both extracts.Keywords: Sensitivity, ESBLs, Enterobacteriaceae, Annona squamosa, Extract

Gap Acceptance Behavior at U - turn Median Openings – Case Study in Jordan

U-turns have been considered among the most hazardous locations on highways. The maneuvering of the driver at these locations is quite complex and risky. The behavior of the driver when turning is governed by the gap acceptance concept. In this study, the driver’s gap acceptance behavior at U-turn median openings was studied. 4 U-turn median openings in Irbid City were investigated. Data was collected by video recording. Two models were developed in this study. The first model estimated the time gap accepted by the driver. The second model calculated the turning function, which was used to estimate the probability of accepting gaps. Results showed that male drivers tended to accept shorter gaps than female drivers. Also, younger drivers were more likely to accept shorter gaps than older ones. The waiting time was also found to affect the gap acceptance behavior of the drivers. Drivers tended to accept shorter gaps after longer waiting times
