Study Shows Customer Loyalty Is Getting More Sensitive

Informed 1 hour ago

A new study found that customer loyalty is even more finicky during a pandemic.

The study—conducted by the University of Pennsylvania's Wharton Baker Retailing Center and WisePlum—found that consumers were less loyal to brands they experienced problems with. In fact, 66% of respondents said they had issues during their last shopping trip, up from 60% prior to the pandemic. Consumers were also likely to encounter problems online, with four in five saying they had a problem with an e-commerce experience. (The report also found that 69% of online shoppers experienced issues returning items.)

Belonging to a rewards program didn't increase customers' faithfulness. In fact, 47% of customers who reported belonging to such a program were more likely to encounter problems than those who weren’t part of one.

“Companies love these loyalty programs and think they do wonderful things for them, but if you don’t have the fundamentals right, they’re not going to do much for you,” said Thomas S. Robertson, a marketing professor at the Wharton School, University of Pennsylvania. “And in fact, you might alienate people if you don’t have right.”

The study was conducted in two waves—the first wave in February before the pandemic and then another in May. In the second wave, 78% of consumers said they didn’t contact the retailer when they had a serious problem.

According to Paula Courtney, CEO of WisePlum, people who belong to a loyalty program are 2.5 times more likely to contact, but the process for those to get the problems results is “terrible.” She said loyal consumers had to make an average of four contacts with a store to get it resolved, versus an average of 2.8 for non-loyal shoppers. And the negative impact of contacting or not contacting is “detrimental” for customer loyalty.

Convalescent plasma could reduce death from COVID-19, early data suggests

Informed 4 hours ago

COVID-19 patients treated with the blood of those who have recovered from the infection die at significantly lower rates than those given standard treatments alone, according to a preliminary analysis.

In their analysis the researchers looked at a dozen trials where hospitalized COVID-19 patients received convalescent plasma (CP) therapy — a treatment that involves drawing blood plasma from recovered patients and injecting the antibody-rich fluid into sick patients. The 12 trials, conducted at various sites around the world, included more than 800 participants in total, and when taken together, suggest that patients given plasma were less than half as likely to die as patients given other treatments, according to the report.

Specifically, the mortality rate among patients given plasma was 13%, compared with 25% among patients given standard treatments.

Association of Metformin With Pregnancy Outcomes in Women With Polycystic Ovarian Syndrome Undergoing In Vitro Fertilization

Informed 5 hours ago

Is metformin associated with improved outcomes among women with polycystic ovarian syndrome undergoing in vitro fertilization?

This meta-analysis of 12 randomized clinical trials, which collectively included 1123 women, found that metformin treatment was associated with a decreased risk of ovarian hyperstimulation syndrome among women with polycystic ovarian syndrome undergoing in vitro fertilization but had no association with clinical pregnancy or live birth rates in the total population studied. However, among women with a body mass index of 26 or greater, metformin treatment was associated with an improved clinical pregnancy rate.

The findings of this study suggest that metformin treatment should be carefully considered for women with polycystic ovarian syndrome undergoing in vitro fertilization and may be more preferred among women with a body mass index of 26 or greater.

Assessment of Racial Disparities in Mortality Rates Among Older Adults Living in US Rural vs Urban Counties From 1968 to 2016

Informed 5 hours ago

Do historical trends exist in age-adjusted mortality rates among older adults of Black and White ancestry living in rural and urban counties in the US?

In this cross-sectional study of 3131 US counties over a 49-year period, racial disparities in the mortality rates of men, with the exception of men living in rural counties, decreased compared with women. Rural and urban disparities were associated with socioeconomic differences among men and women of both races, and these disparities were most substantial among Black men.

Although the overall trend in the differences among Black and White older adults’ mortality rate have narrowed in the urban areas, there is considerable widening in mortality rate among Black and White men living in rural counties.

Association of Childhood Maltreatment With Suicide Behaviors Among Young People

Informed 5 hours ago

What is the association between experiences of childhood maltreatment and suicide behaviors in children and young adults?

This systematic review and meta-analysis was based on 79 individual studies with 337 185 unique participants found an association between core types of childhood maltreatment and suicide behaviors in children and young adults. Younger individuals with experiences of sexual abuse who were not under the care of clinicians had higher rates of suicide attempt, and young age was also associated more strongly with suicide ideation.

These findings highlight the need for raising public awareness and incorporating suicide prevention strategies into treatment planning and suggest that a primary focus of psychological treatments should be the amelioration of the effects of adverse childhood experiences.

Treating prostate cancer with combined hormonal-radiation therapy

Informed 5 hours ago

Androgens, the family of male sex hormones that includes testosterone, function as a fuel for growth in normal development. However, in some men they can also drive the progression of prostate cancer. Hormonal therapy treats prostate cancer by dramatically reducing levels of testosterone and other androgens.

Hormonal therapy is sometimes given in conjunction with external beam radiation to boost the effectiveness of treatment. Hormonal therapy may also be used to shrink the size of large prostate glands (typically defined as those weighing more than 50 grams) before brachytherapy takes place, to enable proper placement of the radioactive seeds.

To learn more about this treatment and other options, read the Annual Report on Prostate Disease from Harvard Medical School.

Epidemiologists predict the future of the coronavirus pandemic

Informed 6 hours ago

Around the world, epidemiologists are constructing short- and long-term projections to prepare for, and potentially mitigate, the spread and impact of SARS-CoV-2, the virus that causes COVID-19. Although their forecasts and timelines vary, modellers agree on two things: COVID-19 is here to stay, and the future depends on a lot of unknowns, including whether people develop lasting immunity to the virus, whether seasonality affects its spread and — perhaps most importantly — the choices made by governments and individuals. In some places, such as in the United States and Brazil, rapid rises in cases have modellers worried. Elsewhere, where lockdowns are easing, early evidence suggests that the ‘new normal’ of hand-washing and mask wearing is helping to stem second waves.

Association of Migraine With Aura and Other Risk Factors With Incident Cardiovascular Disease in Women

Informed 6 hours ago

Is there an association between migraine with aura and cardiovascular disease (CVD) incidence rates in women, relative to that of other major vascular risk factors?

In this cohort study that included 27 858 female health professionals aged at least 45 years, the adjusted incidence rate of major CVD was 3.36 per 1000 person-years for women who reported migraine with aura and 2.11 per 1000 person-years for women who reported migraine without aura or no migraine, a difference that was statistically significant.

Among female health professionals aged at least 45 years, self-reported migraine with aura was associated with increased incidence rates of CVD, but the clinical importance of this finding remains to be determined.

How thoughts could one day control electronic prostheses, wirelessly

Informed 7 hours ago

Stanford researchers have been working for years to advance a technology that could one day help people with paralysis regain use of their limbs, and enable amputees to use their thoughts to control prostheses and interact with computers.

The team has been focusing on improving a brain-computer interface, a device implanted beneath the skull on the surface of a patient's brain. This implant connects the human nervous system to an electronic device that might, for instance, help restore some motor control to a person with a spinal cord injury, or someone with a neurological condition like amyotrophic lateral sclerosis, also called Lou Gehrig's disease.

The current generation of these devices record enormous amounts of neural activity, then transmit these brain signals through wires to a computer. But when researchers have tried to create wireless brain-computer interfaces to do this, it took so much power to transmit the data that the devices would generate too much heat to be safe for the patient.

How tumor cells evade the immune defense

Informed 7 hours ago

Scientists are increasingly trying to use the body's own immune system to fight cancer. A new study by the University of Bonn and research institutions in Australia and Switzerland now shows the strategies tumor cells use to evade this attack. The method developed for this work contributes to a better understanding of the "arms race" between immune defense and disease. The results could help to improve modern therapeutic approaches.

Researchers Discover Predictor of Laser Treatment Success in Patients with Glaucoma

Informed 7 hours ago

More than 70 million people worldwide suffer from glaucoma, a condition that causes a build-up of fluid and pressure inside the eye and can eventually lead to blindness. Treatment options have traditionally included eye drops to reduce the fluid the eye produces or surgery to unclog the eye’s drainage.

But a new study from the University of Missouri School of Medicine and MU Health Care provides insight into which patients might benefit most from a noninvasive treatment called selective laser trabeculoplasty (SLT), which relieves pressure by using a laser to alter the eye tissue, resulting in better fluid drainage.

Discovery shows promise for treating Huntington's Disease

Informed 8 hours ago

Scientists have identified an enzyme that can play a central role in developing a new route of treatment for Huntington's Disease.

Huntington disease is a progressive and aggressively debilitating brain disorder that causes uncontrolled movements, psychological problems, and loss of cognition. It is caused by a mutation in the gene that encodes the protein huntingtin, causing it to build an abnormally long tail of the amino acid glutamine. This tail prevents huntingtin from folding properly and as a result it aggregates inside neurons of the brain, and eventually kills them.
