Background
There are no clear consensus guidelines on the indications and types of anticoagulation therapies in patients with bio-prosthetic valves either with concomitant atrial fibrillation (AF) or ...sinus rhythm. In our meta-analysis, we assessed the safety and efficacy of DOACs as compared to the standard treatment with warfarin in patients with AF and bioprosthetic valves.
Methods
We included randomized controlled trials (RCTs), cohort studies in the English language, and studies reporting patients with valvular heart disease that included bioprosthetic valvular disease. A systematic literature review using Embase, PubMed, and Web of Science was performed using the terms “Direct Acting Oral Anticoagulant,” “Oral Anticoagulants,” “Non-Vitamin K Antagonist Oral Anticoagulant,” “Atrial Fibrillation,” “Bioprosthetic Valve” for literature published prior to January 2021. Extraction of data from included studies was carried out independently by three reviewers from Covidence. We assessed the methodical rigor of the included studies using the modified Downs and Black checklist.
Results
Four RCTs and one observational study (n=1776) were included in our study. A random-effect model using RevMan (version 5.4; The Nordic Cochrane Centre, The Cochrane Collaboration, Copenhagen) was used for data analysis. The pooled data showed that there was a non-significant reduction in the incidence of stroke and systemic embolism in the patients taking DOACs as compared to warfarin (HR 0.69; 95% CI, 0.29, 1.67; I
2
= 50%). The incidence of major bleeding was lower in the DOACs group; the difference was statistically significant (HR 0.42; 95% CI, 0.26, 0.67; I
2
= 7%). The difference was not statistically significant for all-cause mortality in both groups (HR 1.24; 95% CI, 0.91, 1.67; I
2
= 0%).
Conclusion
Our results showed that there was no difference in the outcomes of stroke and systemic embolism between DOACs and warfarin but there were statistically significantly lower major bleeding events. We conclude that larger clinical trials are needed to assess the true safety and efficacy of DOACs in patients with AF and bioprosthetic valves.

This study investigated the efficiency of rice husk carbon (RHC) for lead (Pb (II)) adsorption. The developed RHC was characterized by CHNS analyser, FTIR and FESEM. BET surface area, micropore area, ...micropore volume and average pore diameter of RHC were 58.54 m.sup.2/g, 14.53 m.sup.2/g, 0.007209 mL/g, and 45.46 Å, respectively. Batch adsorption experiments were conducted to assess the effect of initial pH, contact time, initial Pb (II) concentration and RHC dose on Pb (II) removal. A contact time of 120 min and a pH value of 5 were found as optimum for Pb (II) adsorption; maximum adsorption occurred at 8 g/L of RHC dose. Artificial neural network (ANN) was applied to model Pb (II) adsorption. For prediction of Pb (II) adsorption from aqueous solution by RHC, the smallest mean square error (MSE) and the largest coefficient of determination (R.sup.2) values were, respectively, obtained as 6.0053 and 0.988567 with Levenberg-Marquardt algorithm (LMA). Hence, it was selected as the best training algorithm. Traincgf and traincgp functions followed this function with a MSE of 6.1496 and 6.2967, respectively. Adsorption of Pb (II) by RHC followed pseudo-second-order kinetics. The experimental data were described well by both Langmuir and Freundlich isotherm models. Thermodynamics study revealed that Pb (II) adsorption by RHC was spontaneous and endothermic, and the system randomness increased during the whole process. Pb (II) adsorption capacity of RHC was compared with different adsorbents. As evidenced by its high adsorption capacity, RHC can be used as an effective adsorbent for Pb (II) removal from aqueous solutions and wastewaters.
Swietenia macrophylla or commonly known as big leaf mahogany, has been traditionally used as an antibacterial and antifungal agent.
The unwanted problem of antibiotic resistance in many bacterial ...species advocates the need for the discovery of the new anti-infective drugs. Here, we investigated the anti-infective properties of Swietenia macrophylla with an assay involving lethal infection of Caenorhabditis elegans with the opportunistic human pathogen Pseudomonas aeruginosa.
Using a slow killing assay, Caenorhabditis elegans was challenged with an infective strain of Pseudomonas aeruginosa (PA14). The ability of Swietenia macrophylla seed ethyl acetate extract to promote the survival of infected worms was assessed by comparing the percentage of survival between extract treated and non-treated worm populations. The effect of Swietenia macrophylla towards PA14 growth, Caenorhabditis elegans feeding rate and degree of PA14 colonization in the worm gut was also evaluated. Lastly, using a fluorescent transgenic Caenorhabditis elegans strain and real time PCR, the effect of Swietenia macrophylla on the expression of lys-7, an immune response gene was also investigated.
Our results demonstrate the ability of Swietenia macrophylla seed ethyl acetate extract in rescuing Caenorhabditis elegans from fatal PA14 infection. Consequently, we showed that the extract promotes the survival without exhibiting any bactericidal effect or perturbation of Caenorhabditis elegans feeding rate. We also showed that Swietenia macrophylla was able to restore the initially repressed lys-7 level in PA14 infected Caenorhabditis elegans.
Swietenia macrophylla extract is able to enhance the ability of Caenorhabditis elegans to survive PA14 infection without directly killing the pathogen. We further showed that the extract boosted the expression of a gene pivotal for innate immunity in Caenorhabditis elegans. Collectively, these findings strongly suggest the presence of compounds within Swietenia macrophylla seed that either reduces Pseudomonas aeruginosa virulence and/or enhance host resistance.

The aim of the study was to prepare potentially cheaper carbon for the adsorptive removal of Zinc Zn(II) from aqueous solution. The adsorption capacity of the prepared carbon to remove Zn(II) from ...aqueous solution was tested and adsorption mechanism was investigated. Rice husk carbon was prepared by acidic treatment of rice husk. The Acidically Prepared Rice Husk Carbon (APRHC) was characterised in terms of surface area, micropore area, micropore volume, average pore diameter and surface morphology. Adsorption of Zn(II) by APRHC was examined. The influence of operating parameters, namely, pH, initial concentration, contact time and adsorbent dose on adsorption of Zn(II) by the APRHC was evaluated. Batch adsorption tests showed that extent of Zn(II) adsorption depended on initial concentration, contact time and pH. Equilibrium adsorption was achieved in 60 min, while maximum Zn(II) adsorption occurred at pH 3. Langmuir and Freundlich isotherms were studied and the equilibrium adsorption data was found to fit well with the Freundlich isotherm model. Langmuir constants Q degree and b were 44 and 0.06 and Freundlich constants K sub( f) and 1/n were 7.31 and 0.38, respectively. Adsorption of Zn(II) by APRHC followed pseudo-second-order kinetics. Being a low-cost carbon, APRHC has potential to be used for the adsorption of Zn(II) from aqueous solution and wastewater in developing countries.
The aim of the study was to prepare potentially cheaper carbon for the adsorptive removal of Nickle Ni (II) from aqueous solution. The adsorption capacity of the prepared carbon to remove Ni (II) ...from aqueous solution was determined and adsorption mechanism was investigated. Rice husk carbon was prepared by incineration in a muffle furnace. The incinerated rice husk carbon (IRHC) was characterised in terms of surface area, micropore area, micropore volume, average pore diameter and surface morphology. Adsorption of Ni (II) by IRHC was examined. The influence of operating parameters, namely, pH, initial concentration and contact time on adsorption of Ni (II) by IRHC was evaluated. Batch adsorption tests showed that extent of Ni (II) adsorption depended on initial concentration, contact time and pH. Equilibrium adsorption was achieved in 120 min, while maximum Ni (II) adsorption occurred at pH 4. Langmuir and Freundlich isotherms were studied and the equilibrium adsorption data was found to fit well with the Langmuir isotherm model. Langmuir constants Q° and b were 14.45 and 0.10, and Freundlich constants Kf and 1/n were 4.0 and 0.26, respectively. Adsorption of Ni (II) by IRHC followed pseudo-second-order kinetics. Being a low-cost carbon, IRHC has potential to be used for the adsorption of Ni (II) from aqueous solution and wastewater in developing countries.
