What is known about the topic?

Patients who die from poisoning are potential organ or tissue donors but may represent an under-referred population.

What did this study ask?

Do Canadian emergency physicians under-refer patients who die from poisoning for organ or tissue donation, and what characteristics influence referral rates?

What did this study find?

In a simulated context, poisoned patients were under-referred as potential organ or tissue donors, and both environmental and clinician characteristics influenced rates.

Why does this study matter to clinicians?

Understanding factors that affect donor referral may decrease the morbidity and mortality for patients waiting for organ or tissue donation.

In the early 1830s and 1840s, a British colonial official by the name of Colonel James Low uncovered evidence for an early culture with Indic traits in a river system known as the Bujang Valley. On the west coast of the Thai-Malay peninsula, the Bujang Valley is today located in the Malaysian state of Kedah. However, it wasn't until just before World War II that excavations took place, conducted by H. G. Quaritch Wales and his wife Dorothy. Their discoveries and subsequent publications led to the first real attempts to explain the origins and extent of this civilisation and its place within the larger South and Southeast Asian world. In the intervening years between Quaritch Wales's excavations and the present day, considerably more research has taken place within the Bujang Valley, though this has not been without controversy. Recently claims and counter-claims regarding the antiquity of Hinduism and Buddhism at the site have arisen in some quarters within Malaysia. It therefore seems pertinent that this material be re-evaluated in light of new scholarship and discoveries as well as the prevailing paradigms of interactions between South and Southeast Asia. This paper presents an updated reading of this material and argues that the Bujang Valley should be seen as a cosmopolitan trading port with substantive evidence for the presence of Hinduism and Buddhism.

The mid-first millennium CE represents a crucial period in the emergence of early polities in Southeast Asia. However, disagreement remains between archaeologists and art historians as to the precise dating of this shift from prehistory to history. This article focuses on the Dvāravatī period and re-evaluates evidence in Thai and Western language publications. A growing number of sites excavated over the past two decades in particular show occupation from c. the fourth to fifth century onwards while others provide a continual sequence stretching back well into the Iron Age. I argue that evidence from these sites makes a strong case for postulating a proto-Dvāravatī period spanning c. the fourth to fifth centuries. In doing so this article proposes this period as the timeframe within which the nascent traits and characteristics of what becomes Dvāravatī in the seventh to ninth centuries are present and gradually developing.

Studies of early Southeast Asia focus largely on its ‘classical states’, when rulers and their entourages from Sukhothai and Ayutthaya (Thailand), Angkor (Cambodia), Bagan (Myanmar), Champa and Dai Viet (Vietnam) clashed, conquered, and intermarried one another over an approximately six-century-long quest for legitimacy and political control. Scholarship on Southeast Asia has long held that such transformations were largely a response to outside intervention and external events, or at least that these occurred in interaction with a broader world system in which Southeast Asians played key roles. As research gathered pace on the prehistory of the region over the past five decades or so, it has become increasingly clear that indigenous Southeast Asian cultures grew in sophistication and complexity over the Iron Age in particular. This has led archaeologists to propose much greater agency in regard to the selective adaptation of incoming Indic beliefs and practices than was previously assumed under early scholarship of the nineteenth and early to mid-twentieth century.

The rapid growth and co-option of the local agriculture movement highlights a need to deepen connections to place-based culture. Selection of plant varieties specifically adapted to regional production and end-use is an important component of building a resilient food system. Doing so will facilitate a defetishization of food systems by increasing the cultural connection to production and consumption. Today's dominant model of plant breeding relies on selection for centralized production and end-use, thereby limiting opportunity for regional differentiation. On the other hand, end-user-driven selection of heirloom varieties with strong cultural and culinary significance may limit productivity while failing to promote continued advances in end-use quality. Farmer-based selection may directly reflect local food culture; however, increasing genetic gains may require increased exchange of germplasm, and collaboration with trained plant breeders. Participatory farmer–breeder–chef collaborations are an emerging model for overcoming these limitations and adding the strength of culturally based plant breeding to the alternative food movement. These models of variety selection are examined within the context of small grain and dry bean production in Western Washington.

Understanding the nutritional demands on serving military personnel is critical to inform training schedules and dietary provision. Troops deployed to Afghanistan face austere living and working environments. Observations from the military and those reported in the British and US media indicated possible physical degradation of personnel deployed to Afghanistan. Therefore, the present study aimed to investigate the changes in body composition and nutritional status of military personnel deployed to Afghanistan and how these were related to physical fitness. In a cohort of British Royal Marines (n 249) deployed to Afghanistan for 6 months, body size and body composition were estimated from body mass, height, girth and skinfold measurements. Energy intake (EI) was estimated from food diaries and energy expenditure measured using the doubly labelled water method in a representative subgroup. Strength and aerobic fitness were assessed. The mean body mass of volunteers decreased over the first half of the deployment ( − 4·6 (sd 3·7) %), predominately reflecting fat loss. Body mass partially recovered (mean +2·2 (sd 2·9) %) between the mid- and post-deployment periods (P< 0·05). Daily EI (mean 10 590 (sd 3339) kJ) was significantly lower than the estimated daily energy expenditure (mean 15 167 (sd 1883) kJ) measured in a subgroup of volunteers. However, despite the body mass loss, aerobic fitness and strength were well maintained. Nutritional provision for British military personnel in Afghanistan appeared sufficient to maintain physical capability and micronutrient status, but providing appropriate nutrition in harsh operational environments must remain a priority.

Significant new opportunities for astrophysics and cosmology have been identified at low radio frequencies. The Murchison Widefield Array is the first telescope in the southern hemisphere designed specifically to explore the low-frequency astronomical sky between 80 and 300 MHz with arcminute angular resolution and high survey efficiency. The telescope will enable new advances along four key science themes, including searching for redshifted 21-cm emission from the EoR in the early Universe; Galactic and extragalactic all-sky southern hemisphere surveys; time-domain astrophysics; and solar, heliospheric, and ionospheric science and space weather. The Murchison Widefield Array is located in Western Australia at the site of the planned Square Kilometre Array (SKA) low-band telescope and is the only low-frequency SKA precursor facility. In this paper, we review the performance properties of the Murchison Widefield Array and describe its primary scientific objectives.
