Adjunctive ivermectin mass drug administration for malaria control on the Bijagos Archipelago of Guinea-Bissau (MATAMAL): a quadruple-blinded, cluster-randomised, placebo-controlled trial.

Background: Arthropod vectors feeding on the blood of individuals treated with ivermectin have substantially increased mortality. Whether this effect will translate into a useful tool for reducing malaria burden at scale is not clear. Our trial aimed to assess whether using ivermectin as an adjunct to mass drug administration (MDA) with dihydroartemisinin-piperaquine would further reduce malaria prevalence.

Validation of a method for the dry preservation and rehydration of Anopheles gambiae sensu lato for parity analysis to assess the impact of vector control measures in the field.

Background: As the control of malaria remains heavily dependent on vector management interventions, it is important to understand the impact of these on mosquito populations. Age-grading is a valuable tool for this; however, logistical challenges in remote, resource-poor areas make current methodologies difficult to incorporate into clinical trials and routine surveillance. Our aim was to validate a methodology that could be easily implemented in such settings.

Protocol for a cluster randomised placebo-controlled trial of adjunctive ivermectin mass drug administration for malaria control on the Bijagós Archipelago of Guinea-Bissau: the MATAMAL trial.

Introduction: As malaria declines, innovative tools are required to further reduce transmission and achieve elimination. Mass drug administration (MDA) of artemisinin-based combination therapy (ACT) is capable of reducing malaria transmission where coverage of control interventions is already high, though the impact is short-lived. Combining ACT with ivermectin, an oral endectocide shown to reduce vector survival, may increase its impact, while also treating ivermectin-sensitive co-endemic diseases and minimising the potential impact of ACT resistance in this context.

Broadening the range of use cases for ivermectin - a review of the evidence.

Ivermectin is a broad-spectrum antiparasitic agent that interferes with glutamate-gated chloride channels found in invertebrates but not in vertebrate species. Mass drug administration (MDA) with ivermectin-based regimes has been a mainstay of elimination efforts targeting onchocerciasis and lymphatic filariasis for more than 3 decades. More recently, interest in the use of ivermectin to control other neglected tropical diseases (NTDs) such as soil-transmitted helminths and scabies has grown.

Counting the cost of major infection and sepsis in New Zealand: an exploratory study using the National Minimum Data Set.

Aim: To explore the population-at-risk and potential cost of a sepsis episode in New Zealand.

Method: Retrospective analysis of the National Minimum Data Set using two code-based algorithms selecting (i) an inclusive cohort of hospitalised patients diagnosed with a 'major infection' with the potential to cause sepsis and (ii) a restricted subset of these patients with a high likelihood of clinical sepsis based on the presence of both a primary admission diagnosis of infection and at least one sepsis-associated organ failure.

Results: In 2016, 24% of all inpatient episodes were associated with diagnosis of a major infection.

The role of birds and mammals in Korean pine (Pinus koraiensis) regeneration dynamics.

This study examined the interrelationships of the fall seed-foraging guild with Korean pine (Pinus koraiensis) and its regeneration. The study took place in old-growth and secondary-growth forests in Northeastern China. Foraging behavior, seed transportation distance, and cache location of various birds and mammals were observed.
