ABSTRACT
BACKGROUND: A tracheostomy is a surgically created opening through the anterior neck tissues and the trachea, into which a tube is inserted. Despite its influence on basic human needs such as respiration, communication and nutrition, little is known about the impact of tracheostomy on patients and their caregivers or what could be done to enable better care and quality of life (QoL) for these individuals. OBJECTIVE: The aim of this review was to better understand the current knowledge related to the experience and QoL of adults living with a tracheostomy and their caregivers so as to be able to improve these experiences. METHOD: A systematic review of the English-language, peer-reviewed literature was conducted in PubMed, Scopus, PsychINFO, Google Scholar, and CINAHL databases. Articles were eligible if they included adult patient or lay caregiver-reported experiences of tracheostomy. RESULTS: Overall, 1080 articles were identified and 17 eligible for inclusion. Fourteen articles reported on experiences of tracheostomy patients, while three focused on those of their caregivers. Studies were conducted in the home setting (n = 5), on a hospital ward (n = 4), in an intensive care unit (n = 3), in an outpatient clinic (n = 3), in a rehab facility (n = 1), and online (n = 1). Patients and their caregivers reported a range of mostly negative experiences related to the care, support, and management of a tracheostomy, speech and communication, wellbeing and QoL, disfigurement and body image, and stigma and social withdrawal. CONCLUSION: Few studies have published data on the patient and caregiver experiences with tracheostomy, especially in the community setting. There is a need to better understand these experiences in order to be able to formulate strategies and provide resources to improve the quality of care and overall QoL of patients with a tracheostomy and their caregivers in-hospital and in the community.

Hylastes ater and Hylurgus ligniperda are introduced pests of re-established Pinus radiata in New Zealand. Both species breed under the bark of stumps in recently harvested areas. Adult maturation feeding on pine seedlings planted in adjacent areas can significantly impact seedling growth, and in severe cases seedlings will die. Entomopathogenic fungi are important natural mortality factors in bark beetle populations, and Beauveria spp. are predominant. Here, we report on the isolation of other fungal species from H. ater in New Zealand. Based on morphological characteristics and sequencing data, two species, Metarhizium flavoviride var. pemphigi and Hirsutella guignardii, were recovered from H. ater. Both are new records for New Zealand and appear to be the first records of these species from bark beetles worldwide.

In New Zealand, two introduced scolytid beetles, Hylastes ater and Hylurgus ligniperda (Curculionidae: Scolytinae) are pests in pine plantations. Investigation of the naturally occurring pathogens of these exotic pests revealed that both are attacked by Beauveria caledonica, a species originally isolated and described from soil in Scotland. The isolates in New Zealand were identical in morphology and conserved DNA region (rDNA, elongation factor alpha) sequence to isolates held in the USDA-ARS insect pathogens culture collection. In bioassay, the B. caledonica isolates were highly pathogenic to adults of H. ligniperda and larvae of Tenebrio molitor. Sporulation was observed on cadavers, confirming the species can utilise the cadavers. As both species were likely to have been introduced to New Zealand from Europe, a search was made for B. caledonica in the northern UK and Ireland. The fungus was found as a naturally-occurring pathogen of the weevil pest, Hylobius abietis (Curculionidae: Scolytinae), developing in spruce and other beetles in forests in both regions.
