Pine disease in sheep on the Cheviots
The following conclusions are drawn from the
main work of the investigation.1. Pine disease in the Cheviot region is a,
nutritional anaemia caused by nineral deficiency in
the soil or herbage of affected areas resulting in
defective iron metabolism.2. The disease occurs in an endemic form on the
Andesite formation in the East Borders. Both hill
land and arable land are involved. The affected district covers an area of approximately 80 square
miles and carries 40,000 head of sheep..3. There is evidence that the disease first
attained serious proportions in the Cheviot region
about the beginning of the nineteenth century. This
was due to far-reaching changes in the system of sheep
husbandry, and in sheep- breeding in particular. It
is probable that the local races of sheep were
formerly resistant to the malady. This view is
supported by the fact that native sheep are maintained
on pining land in Scotland at the present day without
a change of pasture. the problem therefore has a genetic aspect which appears to offer scope for enquiry.

cobalt prevents the occurrence of the disease on.
pining land and also acts as a cure. The beneficial
results obtained from the feeling of iron compounds
are attributable to traces of cobalt in the materials
used.6. Small quantities of phosphorus, free from
cobalt, are of curative and preventive value. The
feeding of phosphorus compounds only, gives successful
results in practice. A deficiency in this element is
regarded as a predisposing cause of the malady.Both phosphorus and cobalt are presumably lacking
in sufficient quantity from the produce of pining soil
The precise significance of cobalt in animal nutrition,
apart from its potency in assisting the utilisation. of
iron, is unknown,7. Experimental evidence shows that no effect is
produced by the administration of traces of copper to
pining sheep.8. The condition is primarily one of mineral
deficiency. The influence of parasitic infestation
of the digestive tract is entirely secondary. The
treatment of pining sheep for mineral deficiency alone,
with materials that possess no known anthelminthic
properties, is successful in well over 95 per cent of
cases. This applies equally to animals which are
mildly affected, and those which are in an alvanced
stage of the malady.9. The disease has a close similarity with bush
sickness in New Zealand, enzootic marasmus in Western
Australia, coast disease in South Australia, and
certain pining diseases in other countries. It
appears to be different in origin from salt sickness
in Florida and lecksucht in Holland.10. In the Border Counties, the nutritional
anaemia represented by pine disease is not confined to
the Andesite formation. it is manifested in various
forms under diverse conditions of soil and of sheep-husbandry. These various types are as follows: -(1) An endemic for of the :disease is found on the
Andesite and also in localised areas on many other
geological formations in the Border Area. This form
occurs both in hill an:i in arable districts. (2) A
sporadic type is liable ' <o occur in a proportion of
the flock on any hill farm, following a severe winter
luring which the stock have become debilitated.(3) A type of anaemia associated with pregnancy, and
also prevalent among small lambs after weaning, is
found in flocks in all districts, both hill and
arable, and on all types of soil.All of these types respond to the same treatment
as nine disease on the Andesite.11. It is probable that the low content of available
phosphorus in many soils in the area has some connection
with the occurrence of these anaemias.12. It is suggested that these various forms of
anaemia ray be widely distributed in other parts of
Scotland.13. The system of mineral feeding worked out
Luring the course of this investigation has been used
upon thousands of sheep with markedly beneficial
results. apart from its effect upon pine disease or
anaemia, it has other advantages. There is a decrease in the proportion of tup-eild ewes, and an
appreciable increase in the number of twin lambs.There is a reduction in the rate of abortion, and, in
lowland flocks, the incidence of pregnancy toxaemia is
lessened. 'Deaths among ewes are reduced. Lambs
make bettor progress while nursing.14. In practice, pine disease and allied conditions
can be prevented, and some of the above advantages
secured, by an annual outlay of one penny per
sheep

The Chelsea Critical Care Physical Assessment Tool (CPAx): validation of an innovative new tool to measure physical morbidity in the general adult critical care population; an observational proof-of-concept pilot study.
Objective To develop a scoring system to measure physical morbidity in critical care – the Chelsea Critical Care Physical Assessment Tool (CPAx). Method The development process was iterative involving content validity indices (CVI), a focus group and an observational study of 33 patients to test construct validity against the Medical Research Council score for muscle strength, peak cough flow, Australian Therapy Outcome Measures score, Glasgow Coma Scale score, Bloomsbury sedation score, Sequential Organ Failure Assessment score, Short Form 36 (SF-36) score, days of mechanical ventilation and inter-rater reliability. Participants Trauma and general critical care patients from two London teaching hospitals. Results Users of the CPAx felt that it possessed content validity, giving a final CVI of 1.00 (P < 0.05). Construct validation data showed moderate to strong significant correlations between the CPAx score and all secondary measures, apart from the mental component of the SF-36 which demonstrated weak correlation with the CPAx score (r = 0.024, P = 0.720). Reliability testing showed internal consistency of α = 0.798 and inter-rater reliability of κ = 0.988 (95% confidence interval 0.791 to 1.000) between five raters. Conclusion This pilot work supports proof of concept of the CPAx as a measure of physical morbidity in the critical care population, and is a cogent argument for further investigation of the scoring system
Assessing the behavioural trajectories of terrorists: The role of psychological resilience
Within studies critically examining terrorist behaviour, the examination of mental health has largely focused on the relationship with the movement towards terrorist involvement. The impact of engagement in terrorism upon mental health has rarely been studied. However, recent research has shown that there is an association between terrorist engagement and the occurrence of mental health problems across the spectrum of terrorist involvement. This work therefore expands on previous research, and disaggregates three discrete stages of terrorist involvement; pre-engagement, engagement, and disengagement, to critically examine the role of psychological resilience on mental health. To determine whether psychological resilience protects against the negative psychological repercussions of terrorist involvement, we undertake cluster analyses. Results indicate that there is a subset of actors who demonstrate psychological resilience, and appear to maintain their mental health despite their experiences during involvement in terrorism
‘CSA-Plan’: strategies to put Climate-Smart Agriculture (CSA) into practice
Large-scale investment is needed to create climate-smart agriculture (CSA) systems. While many government and development agencies are integrating CSA into their policies, programmes, plans and projects, there is little guidance for operational planning and implementation on ways to be climate-smart. Here we present ‘CSA-Plan’. CSA-Plan frames actions needed to design and execute CSA programmes into four components – (i) situation analysis, (ii) targeting and prioritising, (iii) programme design, and (iv) monitoring and evaluation. Each component yields concrete information to operationalise CSA development, separating it from traditional agriculture development. Already, CSA-Plan has shown the capacity to change the discussion around CSA implementation. With iterative co-development, the approaches will become ever more useful, relevant and legitimate to governments, civil society and the private sector alike

Impact of the Chelsea critical care physical assessment (CPAx) tool on clinical outcomes of surgical and trauma patients in an intensive care unit: An experimental study
Background: Critically ill patients following traumatic injury or major surgery are at risk of loss of skeletal muscle mass, which leads to decreased physical function. Early rehabilitation in an intensive care unit (ICU) is thought to preserve or restore physical functioning. The Chelsea critical care physical assessment (CPAx) is a measurement tool used to assess physical function in the ICU. Objectives: To determine whether the use of the CPAx tool as part of physiotherapy patient assessment, in two adult trauma and surgical ICU settings where early patient mobilisation forms part of standard physiotherapy practice, had an impact on ICU and hospital length of stay (LOS) through delivery of problem-oriented treatment plans. Method: A single-centred pre–post quasi-experimental study was conducted. The population was a consecutive sample of surgical and trauma ICU patients. Participants’ functional ability was assessed with the CPAx tool on alternative days during their ICU stay, and rehabilitation goals were modified according to their CPAx score. Intensive care unit and hospital LOS data were collected and compared to data of a matched historical control group. Descriptive and inferential statistics were used. Results: A total of 26 ICU patients were included in the intervention group (n = 26). They received CPAx-guided therapy, and outcomes were matched with ICU patients in the historical control group (n = 26). The median sequential organ failure assessment (SOFA) score was significantly higher in the control group (p = 0.005) (3.5 [IQR 2–6.3]) versus (2 [IQR 1.8–2.5]) for the intervention group. The median admission CPAx score for the intervention group was 33.5 (IQR 16.1–44), and the median ICU discharge score was 38 (IQR 28.5–43.8). No significant differences were found in ICU days (control 2.7 [IQR 1.1–5.2]; intervention 3.7 [IQR 2.3–5.4]; p = 0.27) or hospital LOS (control 13.5 [IQR 9.3–18.3]; intervention 11.4 [IQR 8.4–20.3], p = 0.42). Chelsea critical care physical assessment scores on ICU admission had a moderate negative correlation with hospital LOS (r = -0.58, p = 0.00, n = 23). Chelsea critical care physical assessment scores at ICU discharge had strong positive correlation with discharge SOFA scores (r = 0.7; p = 0.025; n = 10). Conclusion: Problem-oriented patient rehabilitation informed by the CPAx tool resulted in improvement of physical function but did not reduce ICU or hospital LOS. Clinical implications: A higher level of physical function at ICU admission, measured with CPAx, was associated with shorter hospital LOS.South African Society of Physiotherapy Research Foundatio
