Dissociation Without Detonation: A DFT Analysis of the Thermally Induced Fragmentation of Binary Sulfur-Nitrogen Rings and Cages.

Potential thermal dissociation pathways available to binary sulfur nitrides have been explored by density functional theory methods, and the results interpreted in terms of their known thermochemical behavior. The cyclic cation/anion pair SN both undergo concerted (4 + 2) cycloreversions to afford the 3-membered thiadiazirine ring -NSN and, respectively, the SNS cation/anions. A similar pathway has been identified for SN, leading to S and -NSN.

Correction of the Manubriosternal Angle: The Missing Link in the Diagnosis and Management of Anterior Chest Wall "Pectus" Deformities.

A normal manubriosternal angle (MSA) varies between 157 and 161 degrees, and it is either increased (in pectus carinatum) or decreased (in pectus excavatum). Measurements of the MSA can accurately define the severity of both deformities and gauge the degree of response to therapeutic intervention(s). Correction of the MSA during repair of pectus deformity by complete upper transverse sternotomy seems necessary.

Seroprevalence and risk factors for Q fever and Rift Valley fever in pastoralists and their livestock in Afar, Ethiopia: A One Health approach.

Background: Coxiella burnetii, the causative agent of Q fever, and Rift Valley fever virus are two under-researched zoonotic pathogens in Ethiopia. Potential outbreaks of these diseases, in light of the high dependency of nomadic pastoralists on their livestock, poses a risk to both human and animal health in addition to risking the pastoralists livelihoods. Our study aimed to determine the seroprevalence and associated risk factors for Q fever and Rift Valley fever in pastoral communities in the Afar region of north-eastern Ethiopia.

Setting up a nurse-led 2-week-wait head and neck cancer diagnostic service.

The number of urgent '2-week-wait' referrals to hospital for people with suspected head and neck cancer being sent by primary care is constantly growing and it is becoming increasingly difficult for head and neck cancer services to meet this demand. In order for trusts to meet their Faster Diagnosis Standards, there needs to be an effective and efficient way to ensure there is capacity for patients to receive the appropriate assessments and diagnostic investigations without compromising the quality of care delivered. This article presents the proposal of introducing a nurse-led 2-week-wait clinic to meet the ever-growing demands on the service.
