Use of the measure your medical outcome profile (MYMOP2) and W-BQ12 (Well-Being) outcomes measures to evaluate chiropractic treatment: an observational study

Background: The objective was to assess the use of the Measure Yourself Medical Outcome Profile (MYMOP2) and W-BQ12 well-being questionnaire for measuring clinical change associated with a course of chiropractic treatment. Methods: Chiropractic care of the patients involved spinal manipulative therapy (SMT), mechanically assisted techniques, soft tissue therapy, and physiological therapeutic devices. Outcome measures used were MYMOP2 and the Well-Being Questionnaire 12 (W-BQ12). Results: Statistical and clinical significant changes were demonstrated with W-BQ12 and MYMOP2. Conclusions: The study demonstrated that MYMOP2 was responsive to change and may be a useful instrument for assessing clinical changes among chiropractic patients who present with a variety of symptoms and clinical conditions

The importance of setting and therapeutic relationships when delivering chiropractic care to those living with disadvantage

Background: Chiropractic is a mostly privatised health profession within Australia, with people experiencing disadvantage typically having limited access due to financial barriers. However, some universities within Australia offer community outreach clinics where students provide chiropractic care to people living with disadvantage. This demographic experiences higher rates of chronic conditions including musculoskeletal complaints and requires subsidisation to access privatised care. This need also offers opportunity for the chiropractic profession to work within community healthcare teams. A mixed-methods observational study was used to investigate how the unique setting of a student chiropractic community clinic may influence the experience and outcomes of those who attend. Methods: Three patient-reported outcome measures (PROMs) investigated client outcomes: Measure Yourself Medical Outcome Profile (MYMOP); European Five Domain Five Level Quality of Life Questionnaire (EQ-5D-5L); and the Patient Enablement Instrument. The PROMs data were analysed descriptively and inferentially. Interviews were conducted with clients who had received chiropractic care, chiropractic students, clinical supervisors and staff of the centre. Interview data were coded using thematic analysis, and themes were formed using Bronfenbrenner’s socio-ecological systems framework and non-participant observations. Results: Thirty-seven participants completed baseline PROMs and 17 completed follow-ups after four treatments. Seventy-two percent of participants nominated their primary complaint as chronic. Significant change was noted in general health and wellbeing for the MYMOP, pain and disability for the EQ-5D-5L and index scores for the EQ-5D-5L suggested improved health and wellbeing. Most clients experienced higher levels of enablement post treatment. Twelve participants were interviewed (four were clients), with five themes emerging from the interview data. Clients reported their lived experiences impacted their health problems and attending the clinic offered benefits beyond improvement of pain and disability. Conclusions: Interview data suggested that these benefits were due to a combination of therapy, the setting and the relationships formed within that setting. Complementing this, PROM data suggested clients experienced better levels of health and wellbeing and decreased levels of pain and disability. Findings indicated that people who experienced disadvantage may receive broader benefits from attending community centres offering chiropractic care. Services such as chiropractic may be complementary in meeting the healthcare needs of those experiencing disadvantage. © 2022, The Author(s)

Modulation of the human preadipocyte mitochondrial activity by beta-carotene

Increased ROS generation by the overload by metabolic substrates mitochondria paralleled by decrease of antioxidant activity are typical events found in metabolic syndrome and diabetes type 2. Metabolites of beta-carotene (BC) such as retinoic acid (RA), as well as low concentration of reactive oxygen species (ROS) modify the mitochondrial bioenergetic function. The aim of the study was to investigate the effect of beta-carotene on mitochondrial activity in human preadipocytes. BC used in concentrations, 10 or 30 µM, decreased mitochondrial membrane potential, inhibited mitochondrial respiration and decreased cellular ATP content. We conclude, that BC, the known antioxidant may decrease oxidative phosphorylation capacity of mitochondria

A systematic review on the effectiveness of implementation strategies to postpone elective caesarean sections to ≥ 39 + (0-6) weeks of gestation

BACKGROUND Caesarean sections often have no urgent indication and are electively planned. Research showed that elective caesarean section should not be performed until 39 + (0-6) weeks of gestation to ensure best neonatal and maternal health if there are no contraindications. This was recommended by various guidelines published in the last two decades. With this systematic review, we are looking for implementation strategies trying to implement these recommendations to reduce elective caesarean section before 39 + (0-6) weeks of gestation. METHODS We performed a systematic literature search in MEDLINE, EMBASE, CENTRAL, and CINAHL on 3rd of March 2021. We included studies that assessed implementation strategies aiming to postpone elective caesarean section to ≥ 39 + (0-6) weeks of gestation. There were no restrictions regarding the type of implementation strategy or reasons for elective caesarean section. Our primary outcome was the rate of elective caesarean sections before 39 + (0-6) weeks of gestation. We used the ROBINS-I Tool for the assessment of risk of bias. We did a narrative analysis of the results. RESULTS We included 10 studies, of which were 2 interrupted time series and 8 before-after studies, covering 205,954 elective caesarean births. All studies included various types of implementation strategies. All implementation strategies showed success in decreasing the rate of elective caesarean sections performed < 39 + (0-6) weeks of gestation. Risk difference differed from - 7 (95% CI - 8; - 7) to - 45 (95% CI - 51; - 31). Three studies reported the rate of neonatal intensive care unit admission and showed little reduction. CONCLUSION This systematic review shows that all presented implementation strategies to reduce elective caesarean section before 39 + (0-6) weeks of gestation are effective. Reduction rates differ widely and it remains unclear which strategy is most successful. Strategies used locally in one hospital seem a little more effective. Included studies are either before-after studies (8) or interrupted time series (2) and the overall quality of the evidence is rather low. However, most of the studies identified specific barriers in the implementation process. For planning an implementation strategy to reduce elective caesarean section before 39 + (0-6) weeks of gestation, it is necessary to consider specific barriers and facilitators and take all obstetric personal into account.

Apoptosis-related gene expression in glioblastoma (LN-18) and medulloblastoma (Daoy) cell lines

The expression of apoptosis genes in a commercial pre-designed low-density array from Applied Biosystems was evaluated in two human brain cancer cell models, LN-18 and Daoy (HTB-186™) in comparison to the reference human primary endothelial cells under basic conditions. Analysis of the gene expression in the cancer cell lines compared to the normal control revealed features reflecting anti-apoptotic and inflammatory characteristics of the former. There was an overall downregulation of apoptosis-stimulating genes in both cancer cell lines, along with an upregulation of certain apoptosis inhibitors. A number of genes demonstrated statistically significant changes in their expressions, including BAX (BCL2-associated X protein); the CARD4/NLR family, CARD domain containing 4; CASP10 (caspase 10, apoptosis-related cysteine peptidase); DAP1 (death-associated protein kinase 1), and BIRC5 (baculoviral IAP repeat-containing 5). Anti-apoptotic potential in both cell lines was demonstrated by changes in the Bax:Bcl-2 ratio and downregulation of the APAF1 gene in LN18 cells. There was also significant downregulation of extrinsic signals and the TNF/FADD/inflammatory cascade, and upregulation of caspase inhibitors (IAPs). These results provided a novel molecular characterization of important human cancer cell lines, which might provide a useful research tool for investigating the experimental model of the CNS cell

Acupuncture, chiropractic and osteopathy use in Australia: a national population survey

Background There have been no published national studies on the use in Australia of the manipulative therapies, acupuncture, chiropractic or osteopathy, or on matters including the purposes for which these therapies are used, treatment outcomes and the socio-demographic characteristics of users. Methods This study on the three manipulative therapies was a component of a broader investigation on the use of complementary and alternative therapies. For this we conducted a cross-sectional, population survey on a representative sample of 1,067 adults from the six states and two territories of Australia in 2005 by computer-assisted telephone interviews. The sample was recruited by random digit dialling. Results Over a 12-month period, approximately one in four adult Australians used either acupuncture (9.2%), chiropractic (16.1%) or osteopathy (4.6%) at least once. It is estimated that, adult Australians made 32.3 million visits to acupuncturists, chiropractors and osteopaths, incurring personal expenditure estimated to be A$1.58 billion in total. The most common conditions treated were back pain and related problems and over 90% of the users of each therapy considered their treatment to be very or somewhat helpful. Adverse events are reported. Nearly one fifth of users were referred to manipulative therapy practitioners by medical practitioners. Conclusion There is substantial use of manipulative therapies by adult Australians, especially for back-related problems. Treatments incur considerable personal expenditure. In general, patient experience is positive. Referral by medical practitioners is a major determinant of use of these manipulative therapies

Effects of body position on autonomic regulation of cardiovascular function in young, healthy adults

Background: Analysis of rhythmic patterns embedded within beat-to-beat variations in heart rate (heart rate variability) is a tool used to assess the balance of cardiac autonomic nervous activity and may be predictive for prognosis of some medical conditions, such as myocardial infarction. It has also been used to evaluate the impact of manipulative therapeutics and body position on autonomic regulation of the cardiovascular system. However, few have compared cardiac autonomic activity in supine and prone positions, postures commonly assumed by patients in manual therapy. We intend to redress this deficiency. Methods: Heart rate, heart rate variability, and beat-to-beat blood pressure were measured in young, healthy non-smokers, during prone, supine, and sitting postures and with breathing paced at 0.25 Hz. Data were recorded for 5 minutes in each posture: Day 1 - prone and supine; Day 2 - prone and sitting. Paired t-tests or Wilcoxon signed-rank tests were used to evaluate posture-related differences in blood pressure, heart rate, and heart rate variability. Results: Prone versus supine: blood pressure and heart rate were significantly higher in the prone posture (p &lt; 0.001). Prone versus sitting: blood pressure was higher and heart rate was lower in the prone posture (p &lt; 0.05) and significant differences were found in some components of heart rate variability. Conclusion: Cardiac autonomic activity was not measurably different in prone and supine postures, but heart rate and blood pressure were. Although heart rate variability parameters indicated sympathetic dominance during sitting (supporting work of others), blood pressure was higher in the prone posture. These differences should be considered when autonomic regulation of cardiovascular function is studied in different postures

Scholarly teaching practice: ethics issues and responses in research into teaching in tertiary education.

Research into one's own teaching practice, a significant aspect of the scholarship of teaching and learning in tertiary education, raises ethical issues. This paper sets out some ethical issues for teaching staff and their implications for academic management and academic development. It uses a case study of a funded Action Research in Teaching and Learning (ARTL) scheme in the Science, Engineering and Technology Portfolio at RMIT University. It examines the role that academic developers can play in building staff and organisational capability to work ethically with research into teaching practice

Chiropractors` experience and readiness to work in Indigenous Australian Communities: a preliminary cross-sectional survey to explore preparedness, perceived barriers and facilitators for chiropractors practising cross-culturally

Abstract Background Indigenous people make up approximately 3% of the total Australian population and score poorer on all health indices, including back pain. Chiropractors are well placed to alleviate back pain, yet there is no research that considers chiropractors’ readiness to treat Indigenous patients. This study explores chiropractors` experience working with Indigenous Australians, describes perceived barriers and facilitators to chiropractors’ participation in Indigenous Healthcare and their willingness to engage in cultural competency training. Methods This study used a non-representative cross-sectional design and a convenience sample. Participants were recruited via email invitation to complete an online survey and encouraged to send the invitation on to colleagues. A 17-item online-survey measured demographic data, perceived barriers and facilitators related to caring for Indigenous Australians, participants` level of comfort when working in Indigenous health, and their willingness to participate in cultural competency programs to enhance their skills, knowledge and cultural capacity when engaging with Indigenous Australians. Analysis of the data included descriptive statistics as well as thematic analysis of qualitative free text. Results One hundred and twenty-five chiropractors participated in the survey. The majority of participants (86%, n = 108) were employed in private practice. 62% of respondents were members of the Chiropractors' Association of Australia, 41% were Chiropractic and Osteopathic College of Australasia members. 60% of chiropractors considered that they had, or do treat Indigenous patients yet only 4% of respondents asked their patients if they identified as Indigenous. A majority of participants expressed a high level of ‘comfort’ or confidence in working with Indigenous people while only 17% of respondents had undertaken some form of cultural proficiency training. A majority of respondents (62.7%, n = 74) expressed an interest in working with Indigenous Australians and a majority (91%, n = 104) were willing to participate in training to develop Indigenous cultural competency. Conclusions The study points to a need for chiropractors to have access to cultural proficiency training in order to develop the capability and confidence to engage respectfully with their Indigenous patients. This preliminary study has provided the researchers with valuable insights aiding the development and implementation of an Indigenous cultural proficiency program for chiropractors
