Omics-based molecular techniques in oral pathology centred cancer: Prospect and challenges in Africa
: The completion of the human genome project and the accomplished milestones in the human
proteome project; as well as the progress made so far in computational bioinformatics and âbig dataâ processing have
contributed immensely to individualized/personalized medicine in the developed world.At the dawn of precision medicine, various omics-based therapies and bioengineering can now be
applied accurately for the diagnosis, prognosis, treatment, and risk stratifcation of cancer in a manner that was
hitherto not thought possible. The widespread introduction of genomics and other omics-based approaches into
the postgraduate training curriculum of diverse medical and dental specialties, including pathology has improved
the profciency of practitioners in the use of novel molecular signatures in patient management. In addition, intricate
details about disease disparity among diferent human populations are beginning to emerge. This would facilitate the
use of tailor-made novel theranostic methods based on emerging molecular evidences
Efficacy of noninvasive respiratory support modes as postextubation respiratory support in preterm neonates: A systematic review and network metaâanalysis
Efficacy of noninvasive respiratory support modes for primary respiratory support in preterm neonates with respiratory distress syndrome: Systematic review and network metaâanalysis
Objectives
To compare the efficacy of different noninvasive respiratory support (NRS) modes for primary respiratory support of preterm infants with respiratory distress syndrome (RDS).
Design
Systematic review and network metaâanalysis using the Bayesian randomâeffects approach. MEDLINE, EMBASE, and CENTRAL were searched.
Interventions
High flow nasal cannula (HFNC), continuous positive airway pressure (CPAP), bilevel CPAP (BiPAP), noninvasive positive pressure ventilation (NIPPV).
Main Outcome Measures
Requirement of invasive mechanical ventilation (MV), any treatment failure.
Results
A total of 35 studies including 4078 neonates were included. NIPPV was more effective in decreasing the requirement of MV than CPAP (risk ratios [95% credible interval]: 0.60 [0.44, 0.77]) and HFNC [0.66 (0.43, 0.97)]. Surface under the cumulative ranking curve (SUCRA) for NIPPV, BiPAP, HFNC, and CPAP were 0.95, 0.59, 0.32, and 0.13. For the outcome of treatment failure, both NIPPV and BiPAP were more efficacious compared to CPAP and HFNC (0.56 [0.44, 0.71] {NIPPV vs CPAP}, 0.69 [0.51, 0.93] {BiPAP vs CPAP}, 0.42 [0.30, 0.63] {NIPPV vs HFNC}, 0.53 [0.35, 0.81] {BiPAP vs HFNC}). The SUCRA for NIPPV, BiPAP, CPAP, and HFNC were 0.96, 0.70, 0.32, and 0.01. NIPPV was associated with a reduced risk of air leak compared to BiPAP and CPAP (0.36 [0.16, 0.73]; 0.54 [0.30, 0.87], respectively). NIPPV resulted in lesser incidence of bronchopulmonary dysplasia or mortality when compared to CPAP (0.74 [0.52, 0.98]). Nasal injury was lesser with HFNC compared to CPAP (0.15 [0.01, 0.60]).
Conclusions
Most effective primary mode of NRS in preterm neonates with RDS was NIPPV

Sunlight and Soil-Litter Mixing: Drivers of Litter Decomposition in Drylands
Decomposition of leaf litter is a key component of biogeochemical cycles but the mechanisms driving it in arid and semiarid ecosystems (drylands) remain unresolved. Here, we review recent findings that demonstrate dual roles of solar radiation (ultraviolet and photosynthetically active radiation) and soilâlitter mixing as drivers of decomposition in drylands. We focus on the known and potential mechanisms by which these factors influence leaf litter decomposition, explore how the importance of these two drivers may shift over time, and propose possible avenues by which these factors may interact. Special attention is given to UV in sunlight, as this radiation is known to have multiple roles in influencing decomposition and has received considerable recent research attention. We also identify important uncertainties and challenges and offer a generalized conceptual model to guide future research aimed at enhancing our mechanistic understanding and quantitative modeling of the processes by which soil deposition and solar radiation together influence leaf litter decomposition rates in globally extensive dryland ecosystems
