Ecology and conservation of Alseuosmia quercifolia (Alseuosmiaceae) in the Waikato region, New Zealand

The ecology of Alseuosmia quercifolia, a small endemic shrub, was investigated, focussing on its habitat requirements, population dynamics, phenology and reproductive biology, and conservation status. This species occurs most commonly in lowland native forests of the Waikato region of the North Island (north of latitude 38°05'S), but is also found in scattered populations to North Cape. In the Waikato region it typically occupies shady, well-drained, south or south-east facing lower slopes of hills and ranges at altitudes below 400 m. Population structures show considerable variation amongst seven study sites in the Waikato region, with disjunct size classes a reflection of the presence and abundance of introduced browsing mammals. It is a relatively short-lived (less than 50 years), slow-growing species with a fleshy fruit adapted to bird dispersal, but seed dispersal now appears to be primarily by gravity. Flowering occurs early in spring and is synchronous at both individual and population levels, occurring over a 5-week period, with peak flowering during the second and third weeks. While all populations set seed, reproductive output can be negatively affected by persistent browse and by rain during peak flowering. This species is vulnerable because it is highly palatable to introduced mammals and all plants in a population are within browse height. It has relatively narrow habitat specificity, localised distribution, and limited potential to extend its range. We suggest it fulfils the requirements of the category "declining", using the most recent classification of threatened and uncommon plants of New Zealand

Augmenting forearm crutches with wireless sensors for lower limb rehabilitation

Forearm crutches are frequently used in the rehabilitation of an injury to the lower limb. The recovery rate is improved if the patient correctly applies a certain fraction of their body weight (specified by a clinician) through the axis of the crutch, referred to as partial weight bearing (PWB). Incorrect weight bearing has been shown to result in an extended recovery period or even cause further damage to the limb. There is currently no minimally invasive tool for long-term monitoring of a patient's PWB in a home environment. This paper describes the research and development of an instrumented forearm crutch that has been developed to wirelessly and autonomously monitor a patient's weight bearing over the full period of their recovery, including its potential use in a home environment. A pair of standard forearm crutches are augmented with low-cost off-the-shelf wireless sensor nodes and electronic components to provide indicative measurements of the applied weight, crutch tilt and hand position on the grip. Data are wirelessly transmitted between crutches and to a remote computer (where they are processed and visualized in LabVIEW), and the patient receives biofeedback by means of an audible signal when they put too much or too little weight through the crutch. The initial results obtained highlight the capability of the instrumented crutch to support physiotherapists and patients in monitoring usage

Value-based care in surgery : implications in crisis and beyond

Over the past 2 years, surgeons and surgical systems have demonstrated an ability to rapidly adopt value-driven care, triage patients and make evidence-based decisions in response to crisis. Building on these successes, this paper explores a framework to expand these advances in creating a value-based approach to patient care through clinician leadership and state-wide clinical networks

Il monastero benedettino di S. Giorgio in Braida a Verona: nuove prospettive di ricerca sulla rifabbrica romanica (sec. XII)

L’attuale aspetto rinascimentale della chiesa di San Giorgio in Braida è frutto di una serie di interventi promossi dai canonici veneziani di San Giorgio in Alga a partire dalla fine del XV secolo. Il monastero benedettino, tuttavia, fu fondato nella metà dell’XI secolo e completamente ricostruito fra il terzo e il quarto decennio del secolo successivo per volere del vescovo Bernardo. L’articolo ripercorre le vicende storiche dell’istituzione in età medievale e rende nota l’esistenza di alcune parti della compagine romanica tuttora inedite, che permettono d’inserire il cantiere di San Giorgio in Braida nel contesto delle coeve manifestazioni architettoniche veronesi

Reflections on a health systems response to delivery of surgery during the COVID-19 pandemic : NSW experience

This paper presents a systems level reflection on emerging trends over the course of the pandemic to enable surgical systems to anticipate, monitor, respond and learn to support health system resilience, maintain surgical standards and mitigate workforce burnout

Approaching ancient disease from a One Health perspective: Interdisciplinary review for the investigation of zoonotic brucellosis

Today, brucellosis is the most common global bacterial zoonosis, bringing with it a range of significant health and economic consequences, yet it is rarely identified from the archaeological record. Detection and understanding of past zoonoses could be improved by triangulating evidence and proxies generated through different approaches. The complex socio‐ecological systems that support zoonoses involve humans, animals, and pathogens interacting within specific environmental and cultural contexts, and as such there is a diversity of potential datasets that can be targeted. To capture this, in this paper we consider how to approach the study of zoonotic brucellosis in the past from a One Health perspective, one which explicitly acknowledges the health link between people, animals and environments (both physical and cultural). One Health research is explicitly interdisciplinary and conceptually moves away from an anthropocentric approach, allowing the component parts to be considered in holistic and integrated ways to deliver more comprehensive understanding. To this end, in this paper we review the methods, selected evidence and potential for past brucellosis identification and understanding, focussing on osteological markers in humans and animals, historical, biomolecular and epidemiological approaches. We also present an agenda and potential for future research
