Interleukin-1 type 1 receptor blockade attenuates the exaggerated exercise pressor reflex in male UC Davis type 2 diabetic mellitus rats.

An exaggerated exercise pressor reflex and peripheral neuropathy are both evoked by the same type of thinly myelinated afferents and are present in patients with type 2 diabetes mellitus (T2DM). Although it is known that the pro-inflammatory cytokine interleukin-1β (IL-1β) contributes to peripheral neuropathy, the effects of IL-1β on the exercise pressor reflex in T2DM are not known. Therefore, we aimed to determine the effect of IL-1 receptors on the exercise pressor reflex in T2DM.

Real-World Outcomes of Patients Treated With Gemcitabine Using Standardized Dose and Rate and Docetaxel for Advanced Soft Tissue Sarcoma in an Australian Sarcoma Center.

Background: Gemcitabine and docetaxel (GD) is a common chemotherapy regimen for metastatic soft tissue sarcoma (STS). The GeDDiS trial compared GD with doxorubicin in the first-line setting, using gemcitabine 675 mg/m over a prolonged rate of 90 min-reporting a 20% response rate and 5.4-month median progression-free survival (PFS).

Paramedics Providing Palliative Care at Home: A Retrospective Cohort Study Comparing Symptom Management of Breathlessness and Pain in Cancer Versus Non-Cancer Conditions.

Background Palliative care aims to alleviate pain and distressing symptoms, affirm life, and offer support to patients and their caregivers. For many, the expressed preference is to die at home. As a result, there is growing recognition that paramedics can play an integral role at the end of life for symptom relief.

Validity of Patient-Reported Outcome Measures in Evaluating Nerve Damage Following Chemotherapy.

Importance: Chemotherapy-induced peripheral neuropathy (CIPN) is a substantial adverse effect of anticancer treatments. As such, the assessment of CIPN remains critically important in both research and clinic settings.

Objective: To compare the validity of various patient-reported outcome measures (PROMs) with neurophysiological and sensory functional measures as the optimal method of CIPN assessment.

Plasma Lipidomic Profiling Identifies Elevated Triglycerides as Potential Risk Factor in Chemotherapy-Induced Peripheral Neuropathy.

Purpose: Chemotherapy-induced peripheral neuropathy (CIPN) is a dose-limiting side effect of cytotoxic cancer treatment, often necessitating dose reduction (DR) or chemotherapy discontinuation (CD). Studies on peripheral neuropathy related to chemotherapy, obesity, and diabetes have implicated lipid metabolism. This study examined the association between circulating lipids and CIPN.

Cyclooxygenase products contribute to the exaggerated exercise pressor reflex evoked by static muscle contraction in male UCD-type 2 diabetes mellitus rats.

Cyclooxygenase (COX) products of arachidonic acid metabolism, specifically prostaglandins, play a role in evoking and transmitting the exercise pressor reflex in health and disease. Individuals with type 2 diabetes mellitus (T2DM) have an exaggerated exercise pressor reflex; however, the mechanisms for this exaggerated reflex are not fully understood. We aimed to determine the role played by COX products in the exaggerated exercise pressor reflex in T2DM rats.

Impact of Pain on Symptom Burden in Chemotherapy-Induced Peripheral Neurotoxicity.

Background: Chemotherapy-induced peripheral neurotoxicity (CIPN) affects the quality of life of cancer survivors. However, the impact of pain on symptom burden remains undefined. This study aimed to define differences in the clinical symptom profile of patients with painful and nonpainful CIPN.

Mucinous ovarian carcinoma: A survey of practice in Australia and New Zealand.

Background: Mucinous ovarian carcinoma (MOC) is a rare ovarian cancer with limited evidence to support clinical care.

Aims: We undertook a clinician survey to better understand current practice in treating MOC in Australia and New Zealand, and to determine any features associated with variation in care. In addition, we aimed to understand future research priorities.

Upper-limb dysfunction in cancer survivors with chemotherapy-induced peripheral neurotoxicity.

Introduction: Upper-limb symptoms are often reported in the context of chemotherapy-induced peripheral neurotoxicity (CIPN), but objective quantification of functional deficits is often lacking. We examined and compared a range of neurophysiological and functional assessments of the upper-limb in the assessment of CIPN severity.

Methods: Cross-sectional assessment of neurotoxic chemotherapy-treated patients was undertaken using patient-reported and clinically-graded CIPN measures.

Sleep dysfunction associated with worse chemotherapy-induced peripheral neurotoxicity functional outcomes.

Purpose: Sleep problems are commonly reported by cancer survivors; however, knowledge of the impact of chemotherapy-induced peripheral neurotoxicity (CIPN) on sleep quality remains limited. In this study, we explored the impact of CIPN on sleep quality, as well as identified clinical characteristics associated with poor sleep quality.

Methods: Participants were assessed cross-sectionally post-neurotoxic chemotherapy.

An Australian mainstream genetic testing program: Clinicians views about current and future practices.

Purpose: Germline genetic testing results can guide treatment decisions for oncology patients and are now offered to many cancer patients. Mainstream testing refers to genetic testing arranged by a non-genetics specialist. This repeated cross-sectional study aimed: (1) to capture clinician views on the existing mainstreaming genetic testing program for ovarian, breast, prostate, and endometrial cancer patients, and (2) to ascertain the interest of clinicians to consider changing practice to adopt mainstream testing.

Spontaneous baroreflex sensitivity is attenuated in male UCD-type 2 diabetes mellitus rats: A link between metabolic and autonomic dysfunction.

Patients with type 2 diabetes mellitus (T2DM) have impaired arterial baroreflex function, which may be linked to the co-existence of obesity. However, the role of obesity and its related metabolic impairments on baroreflex dysfunction in T2DM is unknown. This study aimed to investigate the role of visceral fat and adiponectin, the most abundant cytokine produced by adipocytes, on baroreflex dysfunction in T2DM rats.

Patient navigation models for mental health of parents expecting or caring for an infant or young child: A systematic review.

Patient navigation (PN) aims to improve timely access to healthcare by helping patients to "navigate" complex service provision landscapes. PN models have been applied in diverse healthcare settings including perinatal mental health (PMH). However, the practice models and implementation of PN programs vary widely, and their impact on engagement with PMH services has not been systematically investigated.

Patient-Reported Outcome Measures in Chemotherapy-Induced Peripheral Neurotoxicity: Defining Minimal and Clinically Important Changes.

Background: Chemotherapy-induced peripheral neurotoxicity (CIPN) is a common complication of cancer treatment that produces functional disability. Increasingly, patient-reported outcome measures (PROMs) are used to assess CIPN, providing a broader symptom perspective than clinician-graded scales. Understanding when a reported change in CIPN symptoms meets the threshold for clinical significance is challenging.

Exaggerated exercise pressor reflex in male UC Davis type 2 diabetic rats is due to the pathophysiology of the disease and not aging.

Studies in humans and animals have found that type 2 diabetes mellitus (T2DM) exaggerates the blood pressure (BP) response to exercise, which increases the risk of adverse cardiovascular events such as heart attack and stroke. T2DM is a chronic disease that, without appropriate management, progresses in severity as individuals grow older. Thus, it is possible that aging may also exaggerate the BP response to exercise.

Polygenic risk of paclitaxel-induced peripheral neuropathy: a genome-wide association study.

Background: Genetic risk factors for chemotherapy-induced peripheral neuropathy (CIPN), a major dose-limiting side-effect of paclitaxel, are not well understood.

Methods: We performed a genome-wide association study (GWAS) in 183 paclitaxel-treated patients to identify genetic loci associated with CIPN assessed via comprehensive neuropathy phenotyping tools (patient-reported, clinical and neurological grading scales). Bioinformatic analyses including pathway enrichment and polygenic risk score analysis were used to identify mechanistic pathways of interest.

Association of electrochemical skin conductance with neuropathy in chemotherapy-treated patients.

Purpose: Chemotherapy-induced peripheral neuropathy (CIPN) is an adverse event of cancer treatment that can affect sensory, motor, or autonomic nerves. Assessment of autonomic neuropathy is challenging, with limited available tools. Accordingly, it is not routinely assessed in chemotherapy-treated patients.

Providing palliative care at home aligns with the professional identity of paramedics: a qualitative study of paramedics and palliative health care providers.

Background: An innovative program, 'Paramedics Providing Palliative Care at Home,' was implemented in Nova Scotia, Canada in 2015. Roles like this are part of an evolving professional identity; role discordance or lack of clarity not only hinders professionalization but may impair the wellbeing, and career longevity of paramedics. This study explored the alignment of providing palliative support at home with paramedic professional identity.

An International Comparison of Presentation, Outcomes and CORONET Predictive Score Performance in Patients with Cancer Presenting with COVID-19 across Different Pandemic Waves.

Patients with cancer have been shown to have increased risk of COVID-19 severity. We previously built and validated the COVID-19 Risk in Oncology Evaluation Tool (CORONET) to predict the likely severity of COVID-19 in patients with active cancer who present to hospital. We assessed the differences in presentation and outcomes of patients with cancer and COVID-19, depending on the wave of the pandemic.

Physical activity behaviors in cancer survivors treated with neurotoxic chemotherapy.

Aim: There are many barriers to physical activity among cancer survivors. Survivors treated with neurotoxic chemotherapy may develop chemotherapy-induced peripheral neuropathy (CIPN) and experience additional barriers related to sensorimotor and mobility deficits. This study examined physical activity behaviors, including physical activity predictors, among cancer survivors treated with neurotoxic chemotherapies.

Essential Elements to Implementing a Paramedic Palliative Model of Care: An Application of the Consolidated Framework for Implementation Research.

Comfort care without transport to hospital was not traditionally a paramedic practice. The novel includes a new clinical practice guideline, medications, a database to manage and share goals of care, and palliative care training. This study determined essential elements for implementation, scale, and spread of this Program.

Establishment of CORONET, COVID-19 Risk in Oncology Evaluation Tool, to Identify Patients With Cancer at Low Versus High Risk of Severe Complications of COVID-19 Disease On Presentation to Hospital.

Purpose: Patients with cancer are at increased risk of severe COVID-19 disease, but have heterogeneous presentations and outcomes. Decision-making tools for hospital admission, severity prediction, and increased monitoring for early intervention are critical. We sought to identify features of COVID-19 disease in patients with cancer predicting severe disease and build a decision support online tool, COVID-19 Risk in Oncology Evaluation Tool (CORONET).
