All articles published in the British Journal of Oral and Maxillofacial Surgery (BJOMS) and the International Journal of Oral and Maxillofacial Surgery (IJOMS) between January 1999 and December 2009 were classified by study design and evaluated to find the evidence base in oral and maxillofacial surgery (OMFS). Those in related specialties, and the impact factor of related dental journals were also compared. From a total of 3294 articles (1715 (52%) BJOMS; and 1579 (48%) IJOMS) most of the studies were observational or descriptive (36% BJOMS; and 31% IJOMS). Review articles constituted 5% in the British Journal and 6% in the International Journal. Analytical (non-controlled) studies made up 6% and 7% of the studies in the British Journal and the International Journal, respectively. There were 28 randomised controlled trials (RCT) (2%) in the British Journal and 40 (3%) in the International Journal. One meta-analysis was recorded in the International Journal, and one closed loop audit was recorded in the British Journal. Forty percent of the papers in both journals were non-clinical, scientific, or animal studies. The number of RCTs published in OMFS is low and is comparable with the related specialties of ear, nose, and throat (ENT) (1%) and plastic surgery (4%). Greater effort is required to carry out quality research if we are to provide the best possible evidence to patients for our interventions.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Background And Objective: Relevant research has provided valuable insights into risk factors for bicycle crashes at intersections. However, few studies have focused explicitly on three common types of bicycle crashes on road segments: overtaking, rear-end, and door crashes. This study aims to identify risk factors for overtaking, rear-end, and door crashes that occur on road segments.

Since legalization in 2016, the uptake of MAID has increased rapidly to equal or exceed rates in other countries. In that MAID implementation involves numerous ethical/moral complexities, we consider four factors that appear to have influenced this growth.

Studies have noted the connection between Mycobacterium avium subspecies paratuberculosis (MAP) and autoimmunity. MAP is an intracellular pathogen that infects and multiplies in macrophages. To overcome the hostile environment elicited by the macrophage, MAP secretes a battery of virulence factors to neutralize the toxic effects of the macrophage.

Background: People with brain injury can have lower resiliency compared to the general public. Yet, resiliency facilitates positive processes to negotiate adversity after brain injury. Therefore, measuring resiliency after a brain injury is important.
