Summary
Dental hard tissues contain periodic incremental markings that can be used as an absolute temporal archive to reconstruct their growth and can incorporate trace elements into their chemical structure during formation that reflect diet, the environment, metabolism, and health. The growth history can be recovered from teeth using virtual tooth histology to resolve a continuous record of trace element composition within each of the mineralized dental tissues, to further our understanding of past life history events in extant and extinct taxa. While acellular cementum forms slowly and regularly and is ideal for recording annual increments, compensatory cellular cementum can mirror this regular growth through gradual physiological changes in anterior tooth inclination. Here, we document this growth through microstructural elemental mapping using non-destructive synchrotron x-ray fluorescence on chimpanzee dental thin sections. We evidence clear seasonal mineral fluctuations, and match the narrower, brighter incremental markings visible in TLM with peaks in mineral concentration in zinc and strontium.

Background:
The rate of bleeding complications following arterial switch operation is too low to independently justify a prospective randomised study for benefit from recombinant factor VIIa. We aimed to evaluate factor VIIa in a pilot study.
Methods:We performed a retrospective cohort study of patients undergoing arterial switch operation from 2012 to 2017. Nearest-neighbour propensity score matching on age, gender, weight, and associated cardiac defects was used to match 27 controls not receiving recombinant factor VIIa to 30 patients receiving recombinant factor VIIa. Fisher’s exact test was performed to compare categorical variables. Wilcoxon’s rank-sum test was used to compare continuous variables between cohorts.
Results:Post-operative thrombotic complications were not associated with factor VIIa administration (Odds Ratio (OR) 0.28, 95% CI 0.005–3.77, p = 0.336), nor was factor VIIa administration associated with any re-explorations for bleeding. No intraoperative transfusion volumes were different between the recombinant factor VIIa cohort and controls. Post-operative prothrombin time (10.8 [10.3–12.3] versus 15.9 [15.1–17.2], p < 0.001) and international normalised ratio (0.8 [0.73–0.90] versus 1.3 [1.2–1.4], p < 0.001]) were lower in recombinant factor VIIa cohort relative to controls.
Conclusions:In spite of a higher post-bypass packed red blood cell transfusion requirement, patients receiving recombinant factor VIIa had a similar incidence of bleeding post-operatively. With no difference in thrombotic complications, and with improved post-operative laboratory haemostasis, a prospective randomised study is warranted to evaluate recombinant factor VIIa.

Advanced imaging techniques are enhancing research capacity focussed on the developmental origins of adult health and disease (DOHaD) hypothesis, and consequently increasing awareness of future health risks across various subareas of DOHaD research themes. Understanding how these advanced imaging techniques in animal models and human population studies can be both additively and synergistically used alongside traditional techniques in DOHaD-focussed laboratories is therefore of great interest. Global experts in advanced imaging techniques congregated at the advanced imaging workshop at the 2019 DOHaD World Congress in Melbourne, Australia. This review summarizes the presentations of new imaging modalities and novel applications to DOHaD research and discussions had by DOHaD researchers that are currently utilizing advanced imaging techniques including MRI, hyperpolarized MRI, ultrasound, and synchrotron-based techniques to aid their DOHaD research focus.

With more long-acting injectable (LAI) antipsychotics available for treating schizophrenia, each with variable durations of action (2 weeks to 3 months), it is important to have clear management strategies for patients developing breakthrough psychotic symptoms or experiencing symptomatic worsening on LAIs. However, no treatment guidelines or clinical practice pathways exist; health-care providers must rely on their own clinical judgment to manage these patients. This article provides practical recommendations—based on a framework of clinical, pharmacokinetic, and dosing considerations—to guide clinicians’ decisions regarding management of breakthrough psychotic symptoms. Management options include ruling out/addressing medical illness or substance abuse/misuse as a contributing factor, addressing stressors, optimizing nonpharmacologic treatments, treating medical/psychiatric comorbidities, ensuring proper LAI administration technique, addressing missed LAI doses or lack of steady-state attainment, and increasing LAI dose directly or indirectly by shortening the injection interval (off-label). If these strategies do not work sufficiently with frequent monitoring, the LAI could be supplemented with a low dose of the corresponding oral formulation for fast symptom control (off-label). However, caution should be exercised with this strategy, because data on the safety of concomitant use of LAI and oral antipsychotics (OAPs) are limited, especially over extended periods. If symptoms abate, therapy optimization could be continued and slow discontinuation of the OAP could be considered. For persistent/worsening symptoms, the OAP should be increased to optimum effective dose while intensifying the initial steps used before it was added. If this fails, switching the OAP or LAI could be considered. We believe that these strategies will help clinicians manage breakthrough psychotic symptoms during LAI treatment and improve overall outcomes among those who can benefit from LAIs.

Weed science has contributed much to agriculture, forestry and natural resource management during its history. However, if it is to remain relevant as a scientific discipline, it is long past time for weed scientists to move beyond a dominating focus on herbicide efficacy testing and address the basic science underlying complex issues in vegetation management at many levels of biological organization currently being solved by others, such as invasion ecologists and molecular biologists. Weed science must not be circumscribed by a narrowly-defined set of tools but rather be seen as an integrating discipline. As a means of assessing current and future research interests and funding trends among weed scientists, the Weed Science Society of America conducted an online survey of its members in summer of 2007. There were 304 respondents out of a membership of 1330 at the time of the survey, a response rate of 23%. The largest group of respondents (41%) reported working on research problems primarily focused on herbicide efficacy and maintenance, funded mainly by private industry sources. Another smaller group of respondents (22%) reported focusing on research topics with a complex systems focus (such as invasion biology, ecosystem restoration, ecological weed management, and the genetics, molecular biology, and physiology of weedy traits), funded primarily by public sources. Increased cooperation between these complementary groups of scientists will be an essential step in making weed science increasingly relevant to the complex vegetation management issues of the 21st century.

Summary
Abstract Ground sections were prepared of the seven root apices of five teeth preserved in the fossil hemi-mandible specimen, KNM-ER 1817, from Koobi Fora, Kenya
. The sections were studied with transmitted polarised light microscopy. Despite the poor gross macroscopic preservation of the mandibular bone, the dentine microstructure was well preserved. Good details of typical dentine structure were observed in many of the sections including both short-period daily incremental lines and long-period lines. The spacing between consecutive daily incremental lines were compared with those published for dentine in modern humans and other primates. Close to the root surface, there appears to be a consistent rate of ~2.5 µm (micrometres) per day. Coarser accentuated lines (Owen’s lines ) together with long-period lines were also clearly visible in the largest apical root section of the M3. These were used to reconstruct the slowing rates of root extension in the last 4 mm of the mesial M3 apex of KNM-ER 1817, which were then compared with those known for a sample of modern human molars.

Aim
To assess whether a print-based intervention led to increased contact with consumer health organisations (CHOs) by general practice patients with chronic disease.
BackgroundCHOs can enhance people's capacity to manage chronic illness by providing information, education and psychosocial support. However, these organisations appear to be grossly under-utilised by patients and clinicians.
MethodsA total of 276 patients completed a computer-assisted telephone interview before randomisation to an intervention (n = 141) or control (n = 135) group. The intervention consisted of mailed printed materials designed to encourage contact with a CHO relevant to the patient's main diagnosed chronic condition. Follow-up interviews were conducted 4 and 12 months later.
FindingsPatients with conditions other than diabetes who received the intervention were twice as likely as those in the control group to contact a consumer health organisation during the 12-month study period: 41% versus 21% (P < 0.001). No such effect was found for diabetes patients, probably because of pre-existing high levels of contact with diabetes organisations. The intervention package received strong patient endorsement. Low-intensity interventions may be effective in improving access to CHOs for patients with chronic disease.

Summary
Introduction
Enamel is the hard crystalline external covering of teeth, and has a mineral component that closely resembles hydroxyapatite (Boyde, 1989; Brudevold and Soremark, 1967). The chemical constituents of hydroxyapatite are tolerant to substitution by a range of trace elements, and are readily incorporated into enamel formation at the time of environmental exposure. The composition of sub-surface enamel is fixed before tooth emergence, and is therefore able to provide a retrospective and relatively permanent record of the trace elements absorbed during the period of enamel formation. The information locked within this deep enamel can provide evidence of early nutrition, residential mobility, and exposure to toxic metals. The incorporation of some trace elements into enamel hydroxyapatite also has the potential to affect susceptibility to caries. The trace element composition of enamel has a broad relevance in disciplines ranging from dentistry and child health (Brown et al., 2004; Dolphin et al., 2005) to forensics (Gulson et al., 1997a) and archaeology (Budd et al., 2000). Two trace elements of particular interest are lead (Pb) and zinc (Zn).
Lead toxicity remains a major public health concern, particularly in relation to its neurological effects on infants and young children (Bellinger et al., 1984; Goyer, 1996). Lead enters the body from contaminated food and drinking water, and inhaled air and dust, and accumulates gradually in calcified tissues. Non-food sources include lead emissions from gasoline, smelter emissions, lead-based paints and glazed food containers (Jarup, 2003).

Summary
Introduction
A primary goal of paleoanthropology, and indeed all sub-fields of paleontology, is to breathe life, metaphorically speaking, into fossilized remains of extinct species. Parsing out details of the phylogeny of a particular group of extinct organisms, inferring diet from comparative functional analyses of dentognathic remains, reconstructing locomotor repertoires, and sorting out brain/body size scaling relationships, etc., are but a few of the more prominent examples of how researchers make “fossils speak to us” from across vast stretches of time. Ever since the pioneering work of Schultz (1935, 1960), however, primatologists and paleoanthropologists have endeavored to reconstruct aspects of extinct species' schedule of growth, development, maturation, etc. – referred to as life history. Life history, simply put, is the schedule of key events in an organism's life cycle (e.g. gestation length, maternal–infant mass ratio, pre- and postnatal growth rates, age/weight at weaning, age at first reproduction, reproductive span, number of offspring per litter, inter-birth interval, etc.) that enable some individuals of a species to avoid predators or other mortality risks more effectively, or that in some way contribute to overall fitness (Godfrey et al., 2002; Ross, 1998). Thus, life history is the “direct outcome of the interaction between developmental variables (e.g. growth rate, age at skeletal maturation) and demographic variables (survival, reproduction, population growth, life-cycle stage census counts, etc.)” (Godfrey et al., 2002, p. 117).
When viewed in this light, it might seem impossible to infer such reproductive, physiological, and even behavioral parameters from fossilized remains.
