‘Choicest unguents’: molecular evidence for the use of resinous plant exudates in late Roman mortuary rites in Britain
YesResinous substances were highly prized in the ancient world for use in ritual contexts. Details gleaned
from classical literature indicate that they played a significant role in Roman mortuary rites, in treatment
of the body and as offerings at the tomb. Outside of Egypt, however, where research has shown that a
range of plant exudates were applied as part of the mummification process, resins have rarely been
identified in the burial record. This is despite considerable speculation regarding their use across the
Roman Empire.
Focusing on one region, we investigated organic residues from forty-nine late Roman inhumations
from Britain. Using gas chromatographyemass spectrometry and the well-attested biomarker approach,
terpenic compounds were characterized in fourteen of the burials analysed. These results provided direct
chemical evidence for the presence of exudates from three different plant families: coniferous Pinaceae
resins, Mediterranean Pistacia spp. resins (mastic/terebinth) and exotic Boswellia spp. gum-resins
(frankincense/olibanum) from southern Arabia or beyond. The individuals accorded this rite had all
been interred with a package of procedures more elaborate than the norm.
These findings illuminate the multiplicity of roles played by resinous substances in Roman mortuary
practices in acting to disguise the odour of decomposition, aiding temporary soft-tissue preservation and
signifying the social status of the deceased. Nevertheless, it was their ritual function in facilitating the
transition to the next world that necessitated transportation to the most remote outpost of the late
Roman Empire, Britain.R.C.B is supported by a PhD studentship from the Art and Humanities Research Council (43019R00209)

International Nosocomial Infection Control Consortium report, data summary of 50 countries for 2010-2015: Device-associated module
•We report INICC device-associated module data of 50 countries from 2010-2015.•We collected prospective data from 861,284 patients in 703 ICUs for 3,506,562 days.•DA-HAI rates and bacterial resistance were higher in the INICC ICUs than in CDC-NHSN's.•Device utilization ratio in the INICC ICUs was similar to CDC-NHSN's.
Background: We report the results of International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2010-December 2015 in 703 intensive care units (ICUs) in Latin America, Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific.
Methods: During the 6-year study period, using Centers for Disease Control and Prevention National Healthcare Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI), we collected prospective data from 861,284 patients hospitalized in INICC hospital ICUs for an aggregate of 3,506,562 days.
Results: Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAI rates were higher in the INICC ICUs: in the INICC medical-surgical ICUs, the pooled rate of central line-associated bloodstream infection, 4.1 per 1,000 central line-days, was nearly 5-fold higher than the 0.8 per 1,000 central line-days reported from comparable US ICUs, the overall rate of ventilator-associated pneumonia was also higher, 13.1 versus 0.9 per 1,000 ventilator-days, as was the rate of catheter-associated urinary tract infection, 5.07 versus 1.7 per 1,000 catheter-days. From blood cultures samples, frequencies of resistance of Pseudomonas isolates to amikacin (29.87% vs 10%) and to imipenem (44.3% vs 26.1%), and of Klebsiella pneumoniae isolates to ceftazidime (73.2% vs 28.8%) and to imipenem (43.27% vs 12.8%) were also higher in the INICC ICUs compared with CDC-NHSN ICUs.
Conclusions: Although DA-HAIs in INICC ICU patients continue to be higher than the rates reported in CDC-NSHN ICUs representing the developed world, we have observed a significant trend toward the reduction of DA-HAI rates in INICC ICUs as shown in each international report. It is INICC's main goal to continue facilitating education, training, and basic and cost-effective tools and resources, such as standardized forms and an online platform, to tackle this problem effectively and systematically
