Objective: To outline the management of an outbreak of invasive group A Streptococcus (iGAS) in a residential aged-care facility in rural Queensland, Australia, comparing outbreak management with the newly released Australian Series of National Guidelines (SoNG) for this disease and exploring unique aspects of rural iGAS outbreak management. Methods: An outbreak of iGAS was identified in a rural Queensland residential facility, where two cases occurred within 24 hours. A confirmed case was defined as any individual linked to the facility who had laboratory evidence of group A Streptococcus (GAS) in a sterile site. Whole genome sequencing was performed on all confirmed cases. The public health management of this outbreak was conducted according to the Queensland Communicable Disease Control guidelines and was compared with the new SoNG. Results: A phylogenetic tree confirmed that the two samples clustered closely together with a single allele difference. Chemoprophylaxis was offered to all residents and staff in the affected part of the facility; 95% (42/44) of residents consented to chemoprophylaxis. Increased surveillance for GAS and increased facility cleaning were recommended by the public health unit. No additional cases were identified after 30 days of surveillance. Management of the outbreak largely aligned with the SoNG except for post-outbreak surveillance, which would have been extended under the new guidelines. Discussion: This paper highlights factors unique to managing iGAS outbreaks in rural areas. Rural workforce factors and access to pathology services impact rural outbreak management, and thus involving local services and considering the local context are vital. The use of chemoprophylaxis continues to be recommended by the SoNG, and in this case was considered to be an important adjunct to other management strategies.

Rauvolfia serpentina (L.) Benth. Ex Kurz is a greatly appreciated medicinal plant, well-known for its therapeutic benefits in traditional medicine, particularly in Ayurveda, where the roots and whole plant are used to treat a variety of ailments. However, studies focusing on R. serpentina seeds are relatively scarce. Hence, the present study provides a novel approach by analysing the seed oil of R. serpentina extracted using the supercritical-carbon dioxide-fluid-extraction (SCFE) technique. The research employed advanced analytical methods including gas-chromatography with flame ionization detector (GC-FID), gas-chromatography-tandem mass spectrometry (GC-MS/MS), and high performance thin layer chromatography (HPTLC) to characterise the chemical composition of the extracted oil. Functional moieties were evaluated by Fourier transform infrared spectroscopy (FT-IR), while proton nuclear-magnetic-resonance (¹H NMR) spectroscopy was utilised to identify the phytometabolites as well as to assess the physico-chemical parameters. The anti-microbial potential of the supercritically extracted oil was demonstrated through its activity against Klebsiella pneumoniae. The inhibitory effects on K. pneumoniae were quantified using the broth microdilution method, showing activity at both minimum inhibitory concentrations (MIC₅₀ and MIC₉₀). Furthermore, the oil was found to be non-genotoxic, as demonstrated by the Ames assay, which showed no mutagenic effects against S. typhimurium and E. coli WP2 uvrA. Since previous reports on R. serpentina seeds and their novel contribution in the field of pharmaceutics are rather limited, the present study is of utmost importance. The study may pave the way for future investigations into the therapeutic potentials of R. serpentina seeds.

Chronic myeloid leukemia (CML) typically progresses from a chronic phase to an accelerated phase, and eventually to a blast crisis, often involving the bone marrow and peripheral blood, if left untreated. Central nervous system (CNS) involvement is an uncommon manifestation of CML, particularly as an isolated CNS relapse. Here, we present a rare case of CML in lymphoid blast crisis with an isolated CNS relapse. A 46-year-old female with underlying CML in lymphoid blast crisis, previously treated with chemotherapy and tyrosine kinase inhibitors, presented with visual disturbances. Imaging and cerebrospinal fluid analysis confirmed leukemic infiltration of the CNS without evidence of a systemic disease. Isolated CNS involvement is an atypical complication of CML and presents significant therapeutic challenges owing to the blood-brain barrier, which limits the efficacy of systemic therapies. Subsequently, the patient was treated with intrathecal chemotherapy targeting the CNS. Despite aggressive treatment, CNS relapse remains a major concern due to the limited penetration of standard therapies into the CNS. This case underscores the importance of early recognition of CNS symptoms in CML patients, particularly in those with blast crisis, and highlights the need for tailored therapeutic strategies to manage this rare and challenging manifestation.

Purpose: This study aimed to compare the anxiety, depression, and quality of life (QOL) among caregivers of children with cerebral palsy and those caring for typically developing children. Methods: A cross-sectional, comparative study was conducted using convenience sampling to recruit 60 subjects. Anxiety, depression, and QOL were assessed with the Generalized Anxiety Disorder-7 Scale, the Patient Health Questionnaire-9, and the World Health Organization Quality of Life-BREF Scale, respectively. Results: The mean age of caregivers of children with cerebral palsy was 33.63±6.94 years, compared to 32±5.003 years for caregivers of typically developing children. Caregivers of children with cerebral palsy exhibited significantly higher levels of anxiety and depression, as well as poorer QOL, than those caring for typically developing children (P<0.05). Conclusion Caregivers of children with cerebral palsy experience higher levels of anxiety and depression and a poorer QOL compared to caregivers of typically developing children.
