Contact investigations with drug-susceptible tuberculosis (DS-TB) patients have demonstrated a high prevalence of tuberculosis infection (TBI). However, the prevalence of TBI among individuals in close contact with drug-resistant tuberculosis (DR-TB) patients is poorly understood. This systematic review and meta-analysis aimed to determine the prevalence of TBI among household and non-household contacts of DR-TB patients.

Mitophagy preserves overall mitochondrial fitness by selectively targeting damaged mitochondria for degradation. The regulatory mechanisms that prevent PTEN-induced putative kinase 1 (PINK1) and E3 ubiquitin ligase Parkin (PINK1/Parkin)-dependent mitophagy and other selective autophagy pathways from overreacting while ensuring swift progression once initiated are largely elusive. 

At two hospitals in Western Australia, we conducted a prospective, open-label, randomised, controlled trial of 240 patients undergoing tonsillectomy to investigate the effect of chewing a confectionery jelly snake on postoperative nausea and vomiting. The results were published in Anaesthesia Critical Care & Pain Medicine. Recruitment for this study was completed uneventfully between July 2018 and August 2019.

Urbanization combined with climate change are exacerbating water scarcity for an increasing number of the world’s emerging cities. Water and sanitation infrastructure, which in the first place was largely built to cater only to a small subsector of developing city populations, is increasingly coming under excessive strain.

Scabies infection is associated with heightened total IgE immunoglobulin and IgE antibodies to scabies antigens, with both being extremely high for crusted scabies patients. The IgE antibodies cross-react with house dust mite allergens with high reactivity found to the minor allergen arginine kinase.

Scabies is one of the world’s most prevalent diseases, with approximately 147 million cases at any one time and an estimated annual incidence of 455 million new episodes. Although Group A streptococcal (GAS) pharyngitis has long been implicated in the pathogenesis of acute rheumatic fever (ARF) and subsequent rheumatic heart disease (RHD), impetigo caused by GAS has recently been postulated as a link between scabies and the pathogenesis of ARF.

Iron deficiency (ID) is the most common nutritional deficiency affecting young children. Serum ferritin concentration is the preferred biomarker for measuring iron status because it reflects iron stores; however, blood collection can be distressing for young children and can be logistically difficult. A noninvasive means to measure iron status would be attractive to either diagnose or screen for ID in young children.

Reports of a rise in childhood cancer incidence in Australia and globally prompted the investigation of cancer incidence and survival in South Australia and the Northern Territory over a 28-year period, with emphasis on Indigenous peoples.

Atelectasis has been reported in 68 to 100% of children undergoing general anaesthesia, a phenomenon that persists into the recovery period. Children receiving recruitment manoeuvres have less atelectasis and fewer episodes of oxygen desaturation during emergence. The optimal type of recruitment manoeuvre is unclear and may be influenced by the airway device chosen.
