Financial motives drive some doctors’ decisions to offer IVF
Around one in 25 Australian babies are conceived using assisted reproductive technologies (ART), including in-vitro fertilisation (IVF). These interventions are almost all offered in private fertility clinics, backed by a thriving fertility industry. Women who are deemed eligible for IVF can have an unlimited number of cycles subsidised by Medicare, but out-of–pocket costs can range from several hundred to several thousand dollars per cycle. Our research, published today in the journal Human Fertility, suggests the money being made from IVF could be subtly changing the advice doctors give. Informed consent Although IVF is a well-established procedure, it is not without its risks. These include ovarian hyperstimulation syndrome, where hormone levels rise too much (causing abdominal swelling, nausea, vomiting and diarrhoea); obstetric complications such as premature delivery; and psychological distress, especially if the process fails. Although long-term outcomes for children conceived using IVF appear to be similar to non-IVF children, questions remain about possible harmful impacts, including developmental abnormalities and cancer. Given the financial, physical and psychological burdens of IVF, patients must be able to make informed decisions about whether to pursue these treatments in the first place, and when to stop. So it’s concerning that couples are often oversold the likelihood of success
Don’t dismiss conflict-of-interest concerns in IVF, they have a basis
It’s estimated over 5 million children have been born worldwide as a result of assisted reproductive technology treatments. Assisted reproductive technology, an umbrella term that includes in vitro fertilisation (IVF), is a highly profitable global industry, and fertility clinics are increasingly regarded as an attractive investment option. In 2014, two major IVF clinics - Virtus and Monash IVF — floated on the stock exchange. Excited financial analysts observed at the time that: people will pay almost anything to have a baby. Over the past 12 months, there have been numerous critical media analyses of the IVF industry in Australia, including Monday night’s ABC Four Corners program, The Baby Business. The episode suggested IVF doctors are recommending treatments that are expensive, unsafe and likely to be futile. The following morning the Fertility Society of Australia rejected these assertions, saying: Four Corners presented no evidence to support these claims. One of the claims made in the program was that IVF doctors have a financial incentive to treat women with the more invasive practice of IVF. The program suggested this financial incentive conflicts with the doctor’s duty of care towards the patient. Four Corners highlighted the conflicted nature of commercialised IVF, where some IVF doctors are more concerned about their own interests (making money for themselves or their clinics) than they are about their patients. Not surprisingly, the Fertility Society of Australia strongly denied such conflicts of interest exist. It argued that the profession is both highly ethical and highly regulated
X-Ray Synchrotron White Beam Excitation of Auger Electrons
Auger electron spectra have been measured at the Cornell High Energy Synchrotron Source (CHESS), using the full white beam x-ray spectrum as the excitation source. Ordinary Auger spectra obtained in the laboratory with an electron beam source must employ derivative techniques to distinguish the Auger structures from the large background due to the excitation beam. The synchrotron white beam eliminates this source of background and produces signal rates as high as 107 cps. Superior signal-to-background ratios are found for Auger peaks above a few hundred eV, and count rates are large enough to suggest microprobe applications. X-ray induced Auger satellite peaks were observed with intensities much greater than the electron-induced counterpart; this anomaly is not completely understood
Effect of voluntary Health Star Rating labels on healthier food purchasing in New Zealand: Longitudinal evidence using representative household purchase data
Front-of-pack labelling (FoPL) aims to promote healthier diets by altering consumer food purchasing behaviour. We quantify the impact of the voluntary Health Star Rating (HSR) FoPL adopted by New Zealand (NZ) in 2014, on (i) the quantity of foods purchased by HSR scores and food groups and (ii) the quantities of different nutrients purchased. We used Nielsen HomeScan household purchasing panel data over 2013-2019, linked to Nutritrack packaged food composition data. Fixed effects analyses were used to estimate the association of HSR with product and nutrient purchasing. We controlled for NZ-wide purchasing trends and potential confounding at the household and product level. In 2019, HSR-labelled products accounted for 24% (2890) of 12 040 products in the dataset and 32% of purchasing volume. Of HSR-labelled products, 1339 (46%) displayed a rating of 4.0-5.0 stars and 556 (19%) displayed a rating of 0.5-2.0 stars. We found little or no association between HSR labelling and the quantities of different foods purchased. Introduction of HSR was, however, associated with lower sodium (-9%, 95% CI -13% to -5%), lower protein (-3%, 95% CI -5% to 0%) and higher fibre (5%, 95% CI 2% to 7%) purchases when purchased products carrying an HSR were compared with the same products prior to introduction of the programme. Robust evidence of HSR labelling changing consumer purchasing behaviour was not observed. The positive effect on nutrient purchasing of HSR-labelled foods likely arises from reformulation of products to achieve a better HSR label

Relationship Talk With Partners and Friends During Emerging Adulthood: The Role of Relationship Satisfaction
Research indicates that discussing one’s romantic relationship with one’s partner benefits individual well-being and reduces uncertainty about the future of the relationship. Implications of relationship talk with friends remain less clear, though talking with friends may actually increase uncertainty about the relationship (e.g., by making one’s partner jealous of these friends), particularly for emerging adults. Relationship talk with friends may be especially likely to promote relational uncertainty for couples who are already unsatisfied in their relationships. In this study, we explored whether relationship talk with one’s partner and one’s friends would each be uniquely associated with depressive symptoms and uncertainty about the relationship, specifically in the form of perceived partner jealousy of one’s friends and whether these associations would be moderated by relationship satisfaction. Results from a series of path models using data from 202 romantically involved emerging adults in the United States revealed that associations between relationship talk and outcomes were indeed moderated by relationship satisfaction. For example, only in unsatisfied relationships was relationship talk with friends positively associated with a partner\u27s jealousy and negatively associated with depressive symptoms. This research expands our understanding of relationship talk by differentiating between talk with partners versus friends, while considering the contextual role of relationship satisfaction
Evaluation of a hospital-based integrated model of eye care for diabetic retinopathy assessment: A multimethod study
Objectives Diabetic eye disease is a leading cause of blindness but can be mitigated by regular eye assessment. A framework of issues, developed from the literature of barriers to eye assessment, was used to structure an examination of perceptions of a new model of care for diabetic retinopathy from the perspective of staff using the model, and health professionals referring patients to the new service. Design Multimethod: interviews and focus groups, and a separate survey. Setting A new clinic based on an integrated model of care was established at a hospital in outer metropolitan Sydney, Australia in 2017. Funded jointly by Centre for Eye Health (CFEH) and the hospital, the clinic was equipped and staffed by optometrists who work alongside the ophthalmologists in the existing hospital eye clinic. Participants Five (of seven) hospital staff working in the clinic (ophthalmologists and administrative officers) or referring to it from other departments (endocrinologists); nine optometrists from CFEH who developed or worked in the clinic; 10 community-based optometrists as potential referrers. Results The new clinic was considered to have addressed known barriers to eye assessment, including access, assistance for patients unable/unwilling to organise eye checks and efficient management of human resources. The clinic optimised known drivers of this model of care: providing clear scope of practice and protocols for shared care between optometrists and ophthalmologists, good communication between referrers and eye professionals and a collegial approach promoting interprofessional trust. Remaining areas of concern were few referrals from general practitioners, fewer referrals from hospital endocrinologists than expected and issues with stretched administrative capacity. There were also perceived mismatches between the priorities of hospital management and aims of the clinic. Conclusions The new model was considered to have addressed many of the barriers to assessment. While there remain issues with the model, there were also unexpected benefits
The impact of life tables adjusted for smoking on the socio-economic difference in net survival for laryngeal and lung cancer.
BACKGROUND: Net survival is a key measure in cancer control, but estimates for cancers that are strongly associated with smoking may be biased. General population life tables represent background mortality in net survival, but may not adequately reflect the higher mortality experienced by smokers. METHODS: Life tables adjusted for smoking were developed, and their impact on net survival and inequalities in net survival for laryngeal and lung cancers was examined. RESULTS: The 5-year net survival estimated with smoking-adjusted life tables was consistently higher than the survival estimated with unadjusted life tables: 7% higher for laryngeal cancer and 1.5% higher for lung cancer. The impact of using smoking-adjusted life tables was more pronounced in affluent patients; the deprivation gap in 5-year net survival for laryngeal cancer widened by 3%, from 11% to 14%. CONCLUSIONS: Using smoking-adjusted life tables to estimate net survival has only a small impact on the deprivation gap in survival, even when inequalities are substantial. Adjusting for the higher, smoking-related background mortality did increase the estimates of net survival for all deprivation groups, and may be more important when measuring the public health impact of differences or changes in survival, such as avoidable deaths or crude probabilities of death
HUB City Steps: Methods and Early Findings From a Community-Based Participatory Research Trial to Reduce Blood Pressure Among African Americans
Background: Community-based participatory research (CBPR) has been recognized as an important approach to develop and execute health interventions among marginalized populations, and a key strategy to translate research into practice to help reduce health disparities. Despite growing interest in the CBPR approach, CBPR initiatives rarely use experimental or other rigorous research designs to evaluate health outcomes. This behavioral study describes the conceptual frameworks, methods, and early findings related to the reach, adoption, implementation, and effectiveness on primary blood pressure outcomes.
Methods: The CBPR, social support, and motivational interviewing frameworks are applied to test treatment effects of a two-phased CBPR walking intervention, including a 6-month active intervention quasi experimental phase and 12-month maintenance randomized controlled trial phase to test dose effects of motivational interviewing. A community advisory board helped develop and execute the culturally-appropriate intervention components which included social support walking groups led by peer coaches, pedometer diary selfmonitoring, monthly diet and physical activity education sessions, and individualized motivational interviewing sessions. Although the study is on-going, three month data is available and reported. Analyses include descriptive statistics and paired t tests.
Results: Of 269 enrolled participants, most were African American (94%) females (85%) with a mean age of 43.8 (SD = 12.1) years. Across the 3 months, 90% of all possible pedometer diaries were submitted. Attendance at the monthly education sessions was approximately 33%. At the 3-month follow-up 227 (84%) participants were retained. From baseline to 3-months, systolic BP [126.0 (SD = 19.1) to 120.3 (SD = 17.9) mmHg; p \u3c 0.001] and diastolic BP [83. 2 (SD = 12.3) to 80.2 (SD = 11.6) mmHg; p \u3c 0.001] were significantly reduced.
Conclusions: This CBPR study highlights implementation factors and signifies the community’s active participation in the development and execution of this study. Reach and representativeness of enrolled participants are discussed. Adherence to pedometer diary self-monitoring was better than education session participation. Significant decreases in the primary blood pressure outcomes demonstrate early effectiveness. Importantly, future analyses will evaluate long-term effectiveness of this CBPR behavioral intervention on health outcomes, and help inform the translational capabilities of CBPR efforts
