Improvements in clinical signs and symptoms of Parkinson's disease using photobiomodulation: a five-year follow-up.

BACKGROUND: Parkinson's disease is a progressive neurodegenerative disease characterized by clinical motor signs and non-motor symptoms that severely impact quality of life. There is an urgent need for therapies that might slow, halt or even reverse the progression of existing symptoms or delay the onset of new symptoms. Photobiomodulation is a therapy that has shown potential to alleviate some symptoms of Parkinson's disease in animal studies and in small clinical trials. OBJECTIVE: To assess long-term effectiveness of photobiomodulation therapy in a cohort of Parkinson's disease individuals after five years of continuing therapy. METHODS: Eight participants of the initial 12 in a previously published study agreed to be reassessed after five years. Seven of these participants had continued home-based, self-applied photobiomodulation therapy three times per week for five years. One participant had discontinued treatment after one year. Participants were assessed for a range of clinical motor signs, including MDS-UPDRS-III, measures of mobility and balance. Cognition was assessed objectively, and quality of life and sleep quality were assessed using self-reported questionnaires. A Wilcoxon Signed Ranks test was used to evaluate change in outcome measures between baseline (before treatment) and after five years, with the alpha value set to 0.05. RESULTS: Of the seven participants who had continued photobiomodulation therapy, one had a preliminary diagnosis of multisystem atrophy and was excluded from the group analysis. For the remaining six participants, there was a significant improvement in walk speed, stride length, timed up-and-go tests, tests of dynamic balance, and cognition compared to baseline and nonsignificant improvements in all other measures, apart from MDS-UPDRS-III, which was unchanged and one measure of static balance (single leg stance, standing on the unaffected leg with eyes open) which declined. Five of six participants either improved or showed no decline in MDS-UPDRS-III score and most participants showed improvement or no decline in all other outcome measures. No adverse effects of the photobiomodulation therapy were reported. CONCLUSIONS: This study provides a signal that photobiomodulation therapy might safely reduce important clinical motor signs and non-motor symptoms in some Parkinson's disease patients, with improvements maintained over several years. Home-based photobiomodulation therapy has the potential to complement standard therapies to manage symptoms and potentially delay Parkinson's symptom progression.

Evidence of heat sensitivity in people with Parkinson's disease.

Examining how heat affects people with Parkinson's disease is essential for informing clinical decision-making, safety, well-being, and healthcare planning. While there is evidence that the neuropathology associated with Parkinson's disease affects thermoregulatory mechanisms, little attention has been given to the association of heat sensitivity to worsening symptoms and restricted daily activities in people with this progressive disease. Using a cross-sectional study design, we examined the experiences of people diagnosed with Parkinson's disease in the heat. Two-hundred and forty-seven people completed an online survey (age: 66.0 ± 9.2 years; sex: male = 102 (41.3%), female = 145 (58.7%)), of which 195 (78.9%) reported becoming more sensitive to heat with Parkinson's disease. Motor and nonmotor symptoms worsened with heat in 182 (73.7%) and 203 (82.2%) respondents, respectively. The most commonly reported symptoms to worsen included walking difficulties, balance impairment, stiffness, tremor, fatigue, sleep disturbances, excess sweating, difficulty concentrating, and light-headedness when standing. Concerningly, over half indicated an inability to work effectively in the heat, and nearly half reported that heat impacted their ability to perform household tasks and social activities. Overall, heat sensitivity was common in people with Parkinson's disease and had a significant impact on symptomology, day-to-day activities and quality of life.

Effects of photobiomodulation and an aerobic exercise on the level of pain and quality of life in women with fibromyalgia.

To evaluate the effectiveness of photobiomodulation (PBM) in conjunction with an aerobic exercise program (AEP) on the level of pain and quality of life of women with fibromyalgia (FM). METHODS: A double-blinded randomized controlled trial in which 51 participants with FM were allocated into 4 groups: control group (CG) (n = 12); active PBM group (APG) (n = 12); AEP and placebo PBM group (EPPG) (n = 13); AEP and active PBM group (EAPG) (n = 14). AEP was performed on an ergometric bicycle; and a PBM (with an increase dosage regime) [20 J, 32 J and 40 J] was applied using a cluster device. Both interventions were performed twice a week for 12 weeks. A mixed generalized model analysis was performed, evaluating the time (initial and final) and group (EAPG, EPPG, APG and CG) interaction. All analyses were based on intent-to-treat for a significance level of p ≤ 0.05. RESULTS: The intra-group analysis demonstrated that all treated groups presented a significant improvement in the level of pain and quality of life comparing the initial and final evaluation (p < 0.05). Values for SF-36 and 6-minute walk test increased significant in intragroup analysis for EPPG comparing the initial and final evaluation. No intergroup differences were observed. CONCLUSIONS: Both exercised and PBM irradiated volunteers present improvements in the variables analyzed. However, further studies should be performed, with other PBM parameters to determine the best regime of irradiation to optimize the positive effects of physical exercises in FM patients.

Self-control, limited willpower and decision fatigue in healthcare settings.

We argue that willpower as well as its depletion may, in some circumstances, adversely impact on clinical decision-making and patient care. This psychological phenomenon has been dubbed ego depletion in social psychology. Willpower and its depletion which is known as 'ego depletion' are well-established and validated theoretical constructs in social psychology and have been studied across a range of experimental contexts. Willpower is closely related to the concept of self-control, which refers to the ability to regulate one's own behaviour and actions in order to pursue and achieve either a short- or long-term goal. We outline the clinical relevance of willpower and its depletion in relation to clinical case examples drawn from three of the authors' clinical experience with the view of developing a clinical-research agenda for future research studies. We examine willpower and its depletion in the context of three clinical case examples, which include (i) doctor-patient interactions, (ii) willpower and its depletion in relation to challenging interpersonal interactions with clinical and non-clinical work colleagues and (iii) willpower and its depletion in response to working within a challenging and unpredictable clinical environment. In contrast to the more widely recognised external resources (including space, staff allocations and night shifts), a greater understanding of how this important but under-recognised internal resource can be depleted in response to a range of different factors within clinical settings has the potential to inform and improve patient care through a renewed focus on the developing interdisciplinary clinical studies which draw upon contemporary findings from social psychology. Future work aimed at developing evidence-based interventions to help mitigate the negative impact of impaired self-control and decision fatigue within healthcare systems may in turn lead to improved patient care as well as more effective healthcare service and delivery.

Transdisciplinary allied health assessment for patients with stroke: a pre-/post- mixed methods study protocol.

BACKGROUND: Transdisciplinary approaches can streamline processes and build workforce capacity by blurring traditional responsibilities and integrating aspects of care. Emerging evidence shows transdisciplinary approaches can improve time-efficiency, quality of care and cost-effectiveness across various healthcare settings, however no empirical study is based on an acute stroke unit. METHODS: The SPIRIT checklist was used to guide the content of the research protocol. The study is a pragmatic pre-/post- mixed methods four-phase study with a 3-month follow up, based at the Mater Hospital Brisbane. Participants experiencing stroke symptoms will be recruited as they are admitted to the acute stroke unit. Patients presenting with mild stroke symptoms or Transient Ischaemic Attack will be allocated to Phase 1 (baseline) or Phase 2 (implementation), while patients presenting with moderate to severe stroke symptoms will be allocated to Phase 3 (baseline) or Phase 4 (implementation). Participants in baseline Phases 1 and 3 will receive standard allied health assessment, while participants in implementation Phases 2 and 4 will receive the novel transdisciplinary assessment. For the primary aim, allied health professionals will time their assessments to evaluate time taken to administer a novel transdisciplinary assessment, compared to usual discipline-specific assessments. Non-inferiority of the novel transdisciplinary assessment will also be explored in terms of patient safety, compliance to national standards, use of the assessment, and stakeholder perceptions. A retrospective medical record audit, staff focus group, patient/staff surveys, and patient phone interviews at 3-months will be completed. Quantitative results will be estimated using general linear and logistic regression models in Stata 15.1. Qualitative results will be analysed using frequency counts and NVivo software. An economic evaluation will be performed using three scopes including the allied health assessment, hospital admission, and patient outcomes at 3-months. DISCUSSION: When designing the study, pragmatic factors related to staff willingness to be involved, patient safety, and existing clinical pathways/processes were considered. To address those factors, a co-design approach was taken, resulting in staff buy-in, clinically relevant outcome measures, and the pre-/post- four-phase study design.

Improvements in clinical signs of Parkinson's disease using photobiomodulation: a prospective proof-of-concept study.

BACKGROUND: Parkinson's disease (PD) is a progressive neurodegenerative disease with no cure and few treatment options. Its incidence is increasing due to aging populations, longer disease duration and potentially as a COVID-19 sequela. Photobiomodulation (PBM) has been successfully used in animal models to reduce the signs of PD and to protect dopaminergic neurons. OBJECTIVE: To assess the effectiveness of PBM to mitigate clinical signs of PD in a prospective proof-of-concept study, using a combination of transcranial and remote treatment, in order to inform on best practice for a larger randomized placebo-controlled trial (RCT). METHODS: Twelve participants with idiopathic PD were recruited. Six were randomly chosen to begin 12 weeks of transcranial, intranasal, neck and abdominal PBM. The remaining 6 were waitlisted for 14 weeks before commencing the same treatment. After the 12-week treatment period, all participants were supplied with PBM devices to continue home treatment. Participants were assessed for mobility, fine motor skills, balance and cognition before treatment began, after 4 weeks of treatment, after 12 weeks of treatment and the end of the home treatment period. A Wilcoxon Signed Ranks test was used to assess treatment effectiveness at a significance level of 5%. RESULTS: Measures of mobility, cognition, dynamic balance and fine motor skill were significantly improved (p < 0.05) with PBM treatment for 12 weeks and up to one year. Many individual improvements were above the minimal clinically important difference, the threshold judged to be meaningful for participants. Individual improvements varied but many continued for up to one year with sustained home treatment. There was a demonstrable Hawthorne Effect that was below the treatment effect. No side effects of the treatment were observed. CONCLUSIONS: PBM was shown to be a safe and potentially effective treatment for a range of clinical signs and symptoms of PD. Improvements were maintained for as long as treatment continued, for up to one year in a neurodegenerative disease where decline is typically expected. Home treatment of PD by the person themselves or with the help of a carer might be an effective therapy option. The results of this study indicate that a large RCT is warranted.

Photobiomodulation (PBM) therapy at 904 nm mitigates effects of exercise-induced skeletal muscle fatigue in young women.

Muscle fatigue is a process influenced by several mechanisms such as concentration of metabolic substrates, changes in blood flow, and increases in reactive oxygen species that impair contractile muscle function. In this context, photobiomodulation has been investigated for preventing muscle fatigue, with reports of positive effects on muscle performance. This study aimed to investigate the effects of 904-nm LASER photobiomodulation on rectus femoris muscle performance in young women. Eighteen young women participated in a randomized, participant and assessor-blinded crossover trial with placebo control. Active LASER (904 nm, 60 mW, 250 Hz, 3.6 J per diode, total dose of 129.6 J) intervention was applied prior to an isokinetic fatigue protocol consisting of a set of 60 concentric quadricep contractions at a constant dynamometer angular velocity of 180°/s. Compared to placebo, LASER photobiomodulation significantly reduced muscle fatigue across a range of indicators including reduced ratings of perceived exertion (P = 0.0139), and increased electromyographic fatigue index (EFI) (P = 0.005). The isokinetic dynamometer performance analysis demonstrated that LASER photobiomodulation increased peak torque (P = 0.04), time to peak torque (P = 0.042), total work (P = 0.032), average power (P = 0.0007), and average peak torque (P = 0.019) between both experimental conditions. No significant difference was observed for work fatigue index (P = 0.29) or for lactate concentration (P > 0.05). Photobiomodulation at 904 nm was effective in reducing fatigue levels and increasing muscle performance in young active women but had no effect on lactate levels.

Contributing factors, prevention, and management of playing-related musculoskeletal disorders among flute players internationally.

Major studies have shown that flutists report playing-related pain in the neck, middle/upper back, shoulders, wrists, and hands. The current survey was designed to establish the injury concerns of flute players and teachers of all backgrounds, as well as their knowledge and awareness of injury prevention and management. Questions addressed a range of issues including education, history of injuries, preventative and management strategies, lifestyle factors, and teaching methods. At the time of the survey, 26.7% of all respondents were suffering from flute playing-related discomfort or pain; 49.7% had experienced flute playing-related discomfort or pain that was severe enough to distract while performing; and 25.8% had taken an extended period of time off playing because of discomfort or pain. Consistent with earlier studies, the most common pain sites were the fingers, hands, arms, neck, middle/upper back, and shoulders. Further research is needed to establish possible links between sex, instrument types, and ergonomic set up. Further investigation is recommended to ascertain whether certain types of physical training, education, and practice approaches may be more suitable than current methods. A longitudinal study researching the relationship between early education, playing position, ergonomic set-up, and prevalence of injury is recommended.

Utilising an Allied Health Practitioner Capability Audit and Confidence Survey to Identify Implications for Telehealth Safety and Risk-A Chronicle of a Health Service Improvement Activity.

Whilst the benefits of telehealth were identified during the COVID-19 pandemic, we noted barriers to its use at a vital time. Through a health service improvement approach, we sought to increase allied health professional capability in telehealth, but we also sought to understand if there were risks associated with its use. We designed and implemented tools to evaluate allied health professional competence and confidence in using telehealth with private and public patients in a metropolitan teaching hospital setting. With an emphasis on technology capability, we undertook audits over three consecutive years (2020 to 2022) of allied health professional telehealth occasions of service reporting on compliance with the audit criteria and investigating staff confidence in undertaking telehealth sessions using a co-designed survey. The audit tool and confidence survey results were used to identify risk factors to telehealth service delivery using a Modified Health Failure Modes, Effects Analysis. Although confidence levels were relatively high among staff, confidence in managing safety factors and technology risks associated with telehealth were not initially verified by the audit findings. Remedial efforts resulted in service improvements in many identified risk factors, yet technology performance and its troubleshooting remained a primary variable in the ability of staff to comply with the requirements of the real-time audits. Health workers using telehealth should have training to engage safely and effectively in telehealth care and the technology.

Working Towards an Optimal Allied Health Telehealth Service: A Model for Improvement.

Beginning in 2018, Mater Health was enacting its next stage of strategic planning focusing on services designed around consumers and strengthening technology to improve access to care and information for delivering better outcomes. Telehealth was part of the strategy. Allied health services sought to meet future community needs by increasing the number of its offsite or virtual services without the need for expensive infrastructure. Our aim was to reinforce allied health professional capability in telehealth, as part of sustainable allied health telehealth delivery. We used a Model for Improvement that included use of the Plan, Do, Study, Act cycles, incorporating a community of practice and evaluation framework with strategies such as appreciative inquiry designed to enhance communication and understanding among team members. Telehealth has proven of great value to health services and consumers during the COVID-19 pandemic. Scaling up of telehealth during the pandemic resulted in recognition of multiple factors needing to be addressed for telehealth to be sustainable. Our work provides insights into staff and consumer perspectives of TH, forming a basis for future telehealth research.

Localised Objective Characterisation Assessment of Lymphoedema (LOCAL): Using High-Frequency Ultrasound, Bioelectrical Impedance Spectroscopy and Volume to Evaluate Superficial Tissue Composition.

Lymphoedema tissue is characterised by excess free fluid and structural changes to the extracellular matrix (ECM) in the form of fibrotic and fatty deposition. These tissue characteristics are integral to the assessment of lymphoedema progression; however, clinicians and researchers often focus on changes in the free fluid, volume and function of lymphatic vasculature to inform practice. Subsequently, little is known about the effect of clinical interventions on lymphoedema tissue composition. This article presents a novel approach to classify lymphoedema tissue. The Localised Objective Characterisation Assessment of Lymphoedema (LOCAL) classification combines diagnostic and clinically meaningful objective assessment thresholds to infer lymphoedema pathophysiological changes in tissue layers. The LOCAL classification method was verified using data from fifteen women with unilateral breast cancer-related lymphoedema who were evaluated at three sites on each arm using high-frequency ultrasound (HFUS), bio-electrical impedance spectroscopy (BIS) and volume measurements. Participants exhibited an uneven distribution of volume between the proximal and distal segments of the arm (p = 0.023), with multiple tissue compositional categories observed across sites on the same limb (p < 0.001). The LOCAL method demonstrated utility in categorising a diverse range of lymphoedema tissue layer changes beyond what can be ascertained from whole-limb measures.

Pitting Is Not Only a Measure of Oedema Presence: Using High-Frequency Ultrasound to Guide Pitting Test Standardisation for Assessment of Lymphoedema.

The pitting qualities of lymphoedema tissue change with disease progression. However, little is known about the underlying tissue response to the pitting test or the tissue characteristics that enhance or resist indentation. The pitting test is currently unstandardised, and the influence of test technique on pitting outcomes is unknown. Understanding how tissue reacts to applied pressure will build evidence for the standardisation of the pitting test. Ninety pitting test sites from fifteen women with unilateral breast cancer-related lymphoedema were evaluated using high-frequency ultrasound (HFUS), bioelectrical impedance spectroscopy (BIS), and limb volume measures. Three sites on each lymphoedema and non-lymphoedema arm were subject to a 60-s (s) staged pitting test, with changes in tissue features captured with ultrasound imaging before, throughout, and after the pitting test. Pitting qualities of tissues varied greatly, with lymphoedema sites pitting more frequently (p < 0.001) with greater depth (p < 0.001) and requiring a longer recovery time (p = 0.002) than contralateral unaffected tissue. Pitting is not solely attributable to oedema volume. Non-structural and structural characteristics of dermal and subcutaneous layers also influence tissue responses to sustained pressure. To enhance the validity and reliability of pitting assessment, a 60 s staged pitting test with an observation of tissue recovery is recommended for lymphoedema presentations.

Does an allied health transdisciplinary stroke assessment save time, improve quality of care, and save costs? Results of a pre-/post- clinical study.

PURPOSE: Demand for stroke services is increasing. To save time and costs, stroke care could be reorganised using a transdisciplinary assessment model embracing overlapping allied health professional skills. The study compares transdisciplinary assessment to discipline-specific allied health assessment on an acute stroke unit, by evaluating assessment time, quality of care, and cost implications. METHOD: The pre-/post- clinical study used non-randomised groups and 3-month follow-up after hospital admission. Patients with confirmed/suspected stroke received usual discipline-specific allied health assessment (pre-implementation phase) or the novel transdisciplinary assessment (post-implementation phase). Staff/student assessment times (primary outcome) and medical record data (secondary outcomes) were collected. Time differences were estimated using multivariable linear regression controlling for confounding factors. Cost minimisation and sensitivity analyses estimated change in hospital resource use. FINDINGS: When the transdisciplinary assessment was used (N = 116), compared to usual assessment (N = 63), the average time saving was 37.6 min (95% CI -47.5, -27.7; p < 0.001) for staff and 62.2 min (95% CI -74.1, -50.3; p < 0.001) for students. The median number of allied health occasions of service reduced from 8 (interquartile range 4-23) to 5 (interquartile range 3-10; p = 0.011). There were no statistically significant or clinically important changes in patient safety, outcomes or stroke guideline adherence. Improved efficiency was associated with an estimated cost saving of $379.45 per patient (probabilistic 95% CI -487.15, -271.48). DISCUSSION AND CONCLUSION: Transdisciplinary stroke assessment has potential for reorganising allied health services to save assessment time and reduce healthcare costs. The transdisciplinary stroke assessment could be considered for implementation in other stroke services.

Rehabilitation report of 2 cases of spinal cord ischemic injury after intra-aortic repair.

RATIONALE: Spinal cord ischemia injury is a serious complication after intra-aortic surgery, with a low incidence but high disability rate. However, patients often do not receive comprehensive treatment in the early stages of the disease. Therefore, active neurological intervention is needed to protect and prevent spinal cord ischemia during and after surgery. In this paper, rehabilitation program and imaging data of 2 cases with spinal cord ischemic injury are presented and discussed regarding causes, prevention and acute treatment with this disease, which could be referred by clinicians. PATIENT CONCERNS: Case report 1: A 69-year-old male patient underwent aortic arch aneurysm and thoracic endovascular aortic repair (coated stent) was performed under general anesthesia. Complete paralysis of both lower limbs, constipation, and urinary retention occurred after surgery and was subsequently referred to our rehabilitation department. Case report 2: A man aged 41 years experienced sudden chest pain with no dizziness or headache. Weakness of both lower limbs gradually appeared over 30 minutes with subsequent loss of consciousness. He was diagnosed with aortic dissection and underwent aortic stent implantation. Inpatient rehabilitation began systematically 3 months after discharge. DIAGNOSES: The 2 patients were diagnosed with paraplegia and spinal cord ischemic injury. INTERVENTIONS: The patients received strength and transfer training, sensory input, health mission, and activities of daily living. OUTCOMES: Patient 1 returned home without assistive devices and patient 2 returned home with wheelchair. LESSONS: Perioperative spinal cord protection is directly related to postoperative quality of life. Once the symptoms of spinal cord ischemic injury occur, cerebrospinal fluid drainage should be performed as soon as possible to increase mean arterial pressure. At the same time, methylprednisolone, ganglioside, anticoagulation, vasodilator drugs, and symptomatic supportive treatments are required. Intercostal artery and subclavian artery are reconstructed if necessary. Symptom stability flags referral to commence rehabilitation. Repetitive functional training is necessary to help patients return to the family and society as soon as possible.

A Holistic Perspective on How Photobiomodulation May Influence Fatigue, Pain, and Depression in Inflammatory Bowel Disease: Beyond Molecular Mechanisms.

BACKGROUND: Numerous mechanisms, mostly molecular, have been tested and proposed for photobiomodulation. Photobiomodulation is finding a niche in the treatment of conditions that have no gold-standard treatment or only partially effective pharmacological treatment. Many chronic conditions are characterised by symptoms for which there is no cure or control and for which pharmaceuticals may add to the disease burden through side effects. To add quality to life, alternate methods of symptom management need to be identified. OBJECTIVE: To demonstrate how photobiomodulation, through its numerous mechanisms, may offer an adjunctive therapy in inflammatory bowel disease. Rather than considering only molecular mechanisms, we take an overarching biopsychosocial approach to propose how existing evidence gleaned from other studies may underpin a treatment strategy of potential benefit to people with Crohn's disease and ulcerative colitis. MAIN FINDINGS: In this paper, the authors have proposed the perspective that photobiomodulation, through an integrated effect on the neuroimmune and microbiome-gut-brain axis, has the potential to be effective in managing the fatigue, pain, and depressive symptoms of people with inflammatory bowel disease.

Protocol for a Single-Arm Feasibility Study of Photobiomodulation for Fatigue, Depression, and Pain in Inflammatory Bowel Disease.

BACKGROUND: There are limited treatment options for mental health comorbidities associated with Inflammatory Bowel Disease (IBD), although they have been shown to negatively affect the course of IBD and multiple important areas of functioning. Photobiomodulation (PBM) is a new therapeutic intervention using laser-generated low-powered light therapy that has shown early promise in alleviating fatigue, depression, and pain in chronic illness. METHODS: This prospective, single-arm pilot study aims to assess the feasibility and efficacy of PBM in the treatment of fatigue, depression, and pain in youth with IBD. We will recruit 28 young adults with IBD who will receive PBM in addition to treatment as usual. The primary outcome will be fatigue, while secondary outcomes will include depression, pain, quality of life, inflammatory markers, alterations in microbiome composition, physical activity, and functioning. Outcome measures will be assessed at baseline, after a 10-week control period (pre-PBM), at 20 weeks (post-PBM), and at 30 weeks. Feasibility will be assessed by attendance, recruitment rates, and participants' views of PBM. Mixed-effects linear regression modelling will be used to assess the PBM effect on continuous outcomes (fatigue, depression, anxiety and stress scores, and inflammation levels). RESULTS: The study will provide preliminary indicators of PBM feasibility and efficacy in IBD.

Personal protective equipment for COVID-19 among healthcare workers in an emergency department: An exploratory survey of workload, thermal discomfort and symptoms of heat strain.

OBJECTIVES: To examine workload, thermal discomfort and heat-related symptoms among healthcare workers (HCWs) in an Australian ED during the COVID-19 pandemic. METHODS: A cross-sectional study design was employed among HCWs in an ED at a metropolitan hospital in Brisbane, Australia. Respondents provided demographic information including their self-reported age, sex, height, weight, role (e.g. doctor, nurse), and whether they wore personal protective equipment (PPE) during their shift, rated as either Full PPE, Partial PPE, or usual uniform or scrubs. The workload of HCWs was assessed with the National Aeronautics and Space Administration's task load index (NASA-TLX). Thermal discomfort was evaluated using scales from the International Organisation for Standardisation. Responders rated their subjective heat illness using the Environmental Symptoms Questionnaire. RESULTS: Fifty-nine HCWs completed the survey (27 male, 31 female, one prefer not to answer). Overall workload from the NASA-TLX was 64.6 (interquartile range [IQR] 56.5-73.3) for doctors, 72.5 (IQR 63.3-83.3) for nurses and 66.7 (IQR 58.3-74.17) for other staff, representing moderate to high ratings. Eighty-one percent reported thermal sensation to be slightly warm, warm, or hot, and 88% reported being uncomfortable, ranging from slightly to extremely. Ninety-seven percent reported at least one heat-strain symptom. More than 50% reported light-headedness or headache and approximately 30% reported feeling dizzy, faint, or weak. CONCLUSIONS: ED HCWs experience thermal discomfort when wearing PPE. Combined with their workloads, HCWs experienced symptoms related to heat strain. Therefore, careful consideration should be given to managing heat strain among HCWs when wearing PPE in an ED.

Modifying the Microbiome as a Potential Mechanism of Photobiomodulation: A Case Report.

Objective: The objective of this case study was to elucidate the effect of photobiomodulation (PBM) on the microbiome. Background: The gut microbiome has been identified as a key component of health, with gut dysbiosis, characterized by decreased microbial diversity and an altered microbial composition, being recognized as instrumental in many diseases and disorders. Previous research has suggested that the gut microbiome can be favorably altered in animal models using PBM. Materials and methods: The participant had their microbiome tested on nine occasions, three times before any treatment, three times after radiotherapy and commencement of immunotherapy for breast cancer, and three times after PBM treatment. The PBM treatment consisted of infrared laser treatment (904 nm; 700 Hz pulse frequency, 861.3 total joules) to the abdomen three times per week for 11 weeks. Results: The microbiome of the participant showed significant changes in diversity after PBM treatment, but not after cancer therapy, with an increase in the number of known beneficial bacteria (Akkermansia, Faecalibacterium, and Roseburia) and decrease in the number of potentially pathogenic genera. Conclusions: The results suggested the possibility that PBM may alter the microbiome and thus it represents a therapeutic avenue for chronic diseases with otherwise limited treatment options.

Remote Photobiomodulation Treatment for the Clinical Signs of Parkinson's Disease: A Case Series Conducted During COVID-19.

Objective: To assess whether remote application of photobiomodulation (PBM) is effective in reducing clinical signs of Parkinson's disease (PD). Background: PD is a progressive neurodegenerative disease for which there is no cure and few treatment options. There is a strong link between the microbiome-gut-brain axis and PD. PBM in animal models can reduce the signs of PD and protect the neurons from damage when applied directly to the head or to remote parts of the body. In a clinical study, PBM has been shown to improve clinical signs of PD for up to 1 year. Methods: Seven participants were treated with PBM to the abdomen and neck three times per week for 12 weeks. Participants were assessed for mobility, balance, cognition, fine motor skill, and sense of smell on enrolment, after 12 weeks of treatment in a clinic and after 33 weeks of home treatment. Results: A number of clinical signs of PD were shown to be improved by remote PBM treatment, including mobility, cognition, dynamic balance, spiral test, and sense of smell. Improvements were individual to the participant. Some improvements were lost for certain participants during at-home treatment, which coincided with a number of enforced coronavirus disease 2019 (COVID-19) pandemic lockdown periods. Conclusions: Remote application of PBM was shown to be an effective treatment for a number of clinical signs of PD, with some being maintained for 45 weeks, despite lockdown restrictions. Improvements in clinical signs were similar to those seen with the application of remote plus transcranial PBM treatment in a previous study. Clinical Trial Registration number: U1111-1205-2035.

Co-production of a transdisciplinary assessment by researchers and healthcare professionals: a case study.

AIM: One definition of research co-production is a collaboration between researchers and healthcare professionals throughout a research process to facilitate knowledge translation and improve the clinical impact of research findings. In this paper, we present a case study of clinical research co-production and reflect on how the process was facilitated between researchers and healthcare professionals. Type of program or service: Development of a novel transdisciplinary assessment for implementation in an acute stroke unit (ASU). METHODS: Researchers and healthcare professionals integrated perspectives and co-produced a novel transdisciplinary assessment. Team-based activities were guided by a logic model, including task analysis and simulation testing. A logframe matrix was used to plan implementation strategies to mitigate potential risks. RESULTS: Research co-production was fundamental to integrating multiple perspectives to develop an effective, novel transdisciplinary assessment for patients with stroke. Preliminary data demonstrated that the transdisciplinary approach could save up to 103 minutes per patient in assessment time. LESSONS LEARNT: As the project evolved, the three most important factors for research co-production were 1) the right people to integrate critical disciplinary and pragmatic perspectives; 2) a project leader who was inclusive of perspectives held by researchers and healthcare professionals, and 3) structured and non-biased team discussions using a theoretical tool. We recommend these three factors be considered in future research co-production in healthcare settings.
