METHODOLOGY:

• Investigators included participants aged 18-60 years with epilepsy who scored ≥ 4 on the Kilifi Stigma Scale of Epilepsy. A score greater than the 66th percentile indicates the presence of strongly felt stigma.
• Patients (n = 160) had an average of one seizure per week, and most took at least two antiseizure medications.
• The intervention group (n = 80) participated in a yoga module with muscle-loosening exercises, slow and synchronized breathing, meditation, and positive affirmations. The control group (n = 80) participated in sham yoga sessions with no instructions on the breathing exercises or attention to the body movements and sensations during practice.
• Both groups participated in seven 1-hour supervised group yoga sessions over 3 months, were asked to practice the interventions at home five times per week, and received a psychoeducation module on epilepsy.

TAKEAWAY:

• Participants practicing the intervention module had significant reductions in self-perceived stigma, compared with those in the control group (P = .01).
• The proportion of participants in the intervention group who had a more than 50% seizure reduction (odds ratio, 4.11; P = .01) and complete seizure remission (OR, 7.4; P = .005) at the end of the 6-month follow-up was significantly higher than in the control group.
• Compared with those in the control group, there were also significant improvements in anxiety (P = .032) and quality of life (P < .001) in the intervention group.
• The intervention group also experienced significant improvement in mindfulness (P < .001) and cognitive impairment, compared with the control group (P < .004).

IN PRACTICE:

“This stigma can affect a person’s life in many ways, including treatment, emergency department visits, and poor mental health,” study investigator Majari Tripathi, MD, of All India Institute of Medical Sciences, New Delhi, said in a press release. “Our study showed that doing yoga can alleviate the burden of epilepsy and improve the overall quality of life by reducing this perceived stigma.”

SOURCE:

Dr. Tripathi and Kirandeep Kaur, MD, also of All India Institute of Medical Sciences, conducted the study with their colleagues. It was published online in Neurology.

LIMITATIONS:

There was no passive control or treatment as usual group, which would indicate the effect size of the intervention. In addition, there was no monitoring of seizure frequency before the study began, which may have biased the change of seizure frequency as an outcome.

DISCLOSURES:

The study investigators reported no study funding or reported disclosures.

In 2020, 54 million U.S. adults with chronic pain managed their symptoms with a mix of medication and nonpharmacologic therapies but one in four relied on medication alone, data from the Centers for Disease Control and Prevention show.

Results from the annual National Health Interview Survey (NHIS) show that over-the-counter (OTC) pain relievers were the most commonly used pharmacologic treatment and exercise was the most common choice among nonpharmacologic options.

The results also revealed that prescription opioid use for chronic pain decreased from 15.2% in 2019 to 13.5% in 2020. However, there was no corresponding increase in nonpharmacologic therapies, despite current CDC guidelines that recommend maximizing the use of medication alternatives.

“Public health efforts may reduce health inequities by increasing access to pain management therapies so that all persons with chronic pain can receive safe and effective care,” S. Michaela Rikard, PhD, and colleagues wrote.

The findings were published online in a research letter in Annals of Internal Medicine.  

Among 31,500 survey respondents, 7,400 indicated that they had pain on most days or every day for the past 3 months.

The survey collected data on self-reported opioid prescriptions in the past 3 months, as well as prescription and nonprescription opiate use during the same time period.

Among adult respondents, 60% used a combination of pharmacologic and nonpharmacologic treatments for pain and almost 27% used medications alone. Older adults, those with low incomes, uninsured individuals, and those living in the South were among those least likely to turn to nonpharmacologic treatment for pain.

After exercise, complementary therapies were the most commonly used nonpharmacologic options, including massage, meditation, or guided imagery, and spinal manipulation or other forms of chiropractic care.

For those taking medications, 76% self-reported using OTC pain relievers for pain, followed by prescription nonopioids (31%) and prescription opioids (13.5%).

Of those who used both pharmacologic and nonpharmacologic therapies, about half reported nonopioid and nonpharmacologic therapy use and 8% reported combined use of opioids, nonopioids, and nonpharmacologic therapy.

After adjustment for multiple factors, investigators found those who were older, had public insurance, or had more severe pain were more likely to use prescription opioids. They also reported severe pain (22%), but 4% reported only mild pain.

Study limitations included generalizability only to noninstitutionalized civilian adults, potential recall bias, and cross-sectional results that do not include patient or treatment history.

“Despite its limitations, this study identifies opportunities to improve guideline-concordant use of pharmacologic and nonpharmacologic therapies among adults with chronic pain,” the authors wrote.

There was no specific funding source for the study. The authors have reported no relevant financial disclosures.

Leading UK Alzheimer’s organizations have launched an ambitious plan to have a diagnostic Alzheimer’s disease (AD) blood test widely available within the next 5 years.

Alzheimer’s Research UK, the Alzheimer’s Society, and the National Institute for Health and Care Research (NIHR) are collaborating and leading AD researchers to bring a diagnostic blood test to the UK’s National Health Service (NHS).

“Dementia affects around 900,000 people in the UK today, and that number is expected to rise to 1.4 million by 2040. It is the UK’s biggest killer,” Fiona Carragher, with the Alzheimer’s Society, said during a media briefing announcing the project.

Yet, many people face a very long wait of up to 2-4 years to get a dementia diagnosis, and many cases remain undiagnosed, she noted.

A chief reason is lack of access to specialized diagnostic testing. Currently, only 2% of people in the United Kingdom have access to advanced diagnostic tests such as PET scans and lumbar punctures owing to limited availability.

“Getting an early and accurate diagnosis is the pivotal first step to getting help today and unlocking hope for the future” and blood biomarkers provide a “real opportunity to disrupt the diagnostic paradigm,” Ms. Carragher said. It also offers greater opportunities to participate in research and clinical trials, she added.
 

Attitude shift

Susan Kohlhaas, PhD, with Alzheimer’s Research UK, noted that attitudes toward dementia diagnosis have changed in the past few years. The days when people may have not wanted to know if they have dementia are gone.

Data from the latest wave of the Alzheimer’s Research UK Dementia Attitudes Monitor survey show that 9 in 10 people would seek a diagnosis from their provider. “That’s been driven by awareness of treatments and things that people can proactively do to try and slow disease progression,” Dr. Kohlhaas said.

“As new treatments for dementia become available there will to be a surge in people seeking a diagnosis. At the moment, we don’t have adequate infrastructure to cope with that demand,” Dr. Kohlhaas added.

She noted that blood tests are starting to show their potential as an effective part of the diagnosis and are widely used in research.

“In some cases, they are similar in sensitivity to gold-standard PET scans and lumbar punctures, and they’re less expensive and potentially more scalable on the NHS. What we need to do over the next several years is to understand how they fit into the clinical pathway,” Dr. Kohlhaas said.

The project will involve working with leading dementia researchers to pilot the implementation of potential blood tests in the NHS that can give an early and accurate diagnose of dementia.

The project, which kicks off in January 2024, will receive £5 million ($6.13 million) awarded by the UK Postcode Dream Fund. Specific details regarding the leadership team, participating centers, and specific blood biomarker tests to be trialed will be announced then.

Ms. Carragher and Dr. Kohlhaas reported no relevant financial conflicts of interest.

TOPLINE:

A history of military service is associated with a 26% increased risk for amyloid plaque and 10% increased risk for elevated tau tangle levels, underscoring the urgent need for amyloid screening among veterans.

METHODOLOGY:

• The study included 597 male decedents who donated their brains to one of two Alzheimer’s Disease Research Center (ADRC) brain bank programs between 1986 and 2018.
• Researchers conducted public data tracing for historical information on military history, which included searching online commercial genealogical databases and paper archives.
• They evaluated tau tangles (using a B score of neurofibrillary tangle deposition in four stages: B0 [not present], B1 [transentorhinal stages], B2 [limbic stages], and B3 [isocortical stages]) and amyloid plaque pathology (using a C score that classifies neuritic amyloid plaque into four categories: no plaques, sparse, moderate, or frequent).
• The study involved three B score comparisons (1, 2, 3 vs. 0; 2, 3 vs. 0, 1; and 3 vs. 0, 1, 2) and two C score comparisons (sparse, moderate, or frequent vs. no plaques, and moderate or frequent vs. no plaque or sparse).

TAKEAWAY:

• Public record tracing determined that 60% of the sample of male decedents had a history of military service; the median year of birth was 1923 and the median year of death was 2007.
• After adjustment for age and year of death, those with a military service history had a 26% increased risk for a higher neuritic amyloid plaque C score compared with those without such history (odds ratio [OR], 1.26; 95% confidence interval [CI], 1.06-1.49), an increase that applied for both relevant comparisons.
• A history of military service was also associated with a 10% greater adjusted odds of a higher neurofibrillary tangle B score (OR, 1.10; 95% CI, 1.08-1.12), with the increase applying to all three comparisons.
• A sensitivity analysis that included both the male decedents and 556 female decedents (increasing the overall sample to 1,153) and was adjusted for sex in addition to age and year of death showed similar results to the male-only sample estimations for both B and C score comparisons.

IN PRACTICE:

Understanding how military service affects AD biological processes is “essential” from a research perspective, the investigators noted. These new findings “emphasize that targeted AD therapies in the veteran population are urgently needed.”

SOURCE:

The study was conducted by W. Ryan Powell, Center for Health Disparities Research and Department of Medicine, Geriatrics Division, University of Wisconsin School of Medicine and Public Health, and colleagues. It was published online in Alzheimer’s & Dementia.

LIMITATIONS:

Selection bias in brain donation is likely because ADRC cohorts are recruitment based. The study was unable to rigorously identify factors that may explain why individuals with military service are at greater risk of having amyloid and tau neuropathology (including the interplay between environmental and genetic risk factors such as apolipoprotein E status).

DISCLOSURES:

The study was supported by the National Institute on Aging. The authors reported no disclosures.

• A sensitivity analysis that included both the male decedents and 556 female decedents (increasing the overall sample to 1,153) and was adjusted for sex in addition to age and year of death showed similar results to the male-only sample estimations for both B and C score comparisons.

IN PRACTICE:

Understanding how military service affects AD biological processes is “essential” from a research perspective, the investigators noted. These new findings “emphasize that targeted AD therapies in the veteran population are urgently needed.”

SOURCE:

The study was conducted by W. Ryan Powell, Center for Health Disparities Research and Department of Medicine, Geriatrics Division, University of Wisconsin School of Medicine and Public Health, and colleagues. It was published online in Alzheimer’s & Dementia.

LIMITATIONS:

Selection bias in brain donation is likely because ADRC cohorts are recruitment based. The study was unable to rigorously identify factors that may explain why individuals with military service are at greater risk of having amyloid and tau neuropathology (including the interplay between environmental and genetic risk factors such as apolipoprotein E status).

DISCLOSURES:

The study was supported by the National Institute on Aging. The authors reported no disclosures.

TOPLINE:

In the first year of the COVID-19 pandemic, there was a significant drop in working memory and executive function in older individuals. This was attributed to an increase in known dementia risk factors, including increased alcohol use and a more sedentary lifestyle. This trend persisted into the second year of the pandemic, after social restrictions had eased.

METHODOLOGY:

• In total, 3,140 participants (54% women; mean age, 68 years) in the PROTECT study, a longitudinal aging study in the United Kingdom, completed annual cognitive assessments and self-reported questionnaires related to mental health and lifestyle.
• Investigators analyzed cognition across three time periods: during the year before the pandemic (March 2019 to February 2020), during pandemic year 1 (March 2020 to February 2021), and pandemic year 2 (March 2021 to February 2022).
• Investigators conducted a subanalysis on those with mild cognitive impairment and those with a history of COVID-19 (n = 752).

TAKEAWAY:

• During the first year of the pandemic, when there were societal lockdowns totaling 6 months, significant worsening of executive function and working memory was seen across the entire cohort (effect sizes, 0.15 and 0.51, respectively), in people with mild cognitive impairment (effect sizes, 0.13 and 0.40, respectively), and in those with a previous history of COVID-19 (effect sizes, 0.24 and 0.46, respectively).
• Worsening of working memory was sustained across the whole cohort in the second year of the pandemic after lockdowns were lifted (effect size, 0.47).
• Even after investigators removed data on people with mild cognitive impairment and COVID-19, the decline in executive function (effect size, 0.15; P < .0001) and working memory (effect size, 0.53; P < .0001) persisted.
• Cognitive decline was significantly associated with known risk factors for dementia, such as reduced exercise (P = .0049) and increased alcohol use (P = .049), across the whole cohort, as well as depression (P = .011) in those with a history of COVID-19 and loneliness (P = .0038) in those with mild cognitive impairment.

IN PRACTICE:

Investigators noted that these data add to existing knowledge of long-standing health consequences of COVID-19, especially for older people with memory problems. “On the positive note, there is evidence that lifestyle changes and improved health management can positively influence mental functioning,” study coauthor Dag Aarsland, MD, PhD, professor of old age psychiatry at the Institute of Psychiatry, Psychology & Neuroscience of King’s College London, said in a press release. “The current study underlines the importance of careful monitoring of people at risk during major events such as the pandemic.”

SOURCE:

The study was led by Anne Corbett, PhD, of University of Exeter, and was published online in The Lancet Healthy Longevity. The research was funded by the National Institute for Health and Care Research (NIHR) Biomedical Research Centre at South London and Maudsley NHS Foundation Trust and King’s College London and the NIHR Exeter Biomedical Research Centre.

LIMITATIONS:

The study relied on self-reported data. In addition, the PROTECT cohort is self-selected and may skew toward participants with higher education levels.

DISCLOSURES:

Dr. Corbett reported receiving funding from the NIHR and grants from Synexus, reMYND, and Novo Nordisk. Other disclosures are noted in the original article.

Excess consumption of red meat, whether processed or not, is linked to a greater risk for developing type 2 diabetes. This association was confirmed by a new study published in the American Journal of Clinical Nutrition, a data analysis of nearly 217,000 people who were monitored for three decades as part of several cohort studies. “Our study supports the current dietary recommendations of limiting consumption of red meat and highlights the importance of different alternative sources of protein in preventing type 2 diabetes,” the researchers wrote.

Consumption and risk

The study included men and women who took part in the Nurses’ Health Study, the Nurses’ Health Study II, or the Health Professionals Follow-up Study. Questionnaires were used to collect data every 2-4 years on the frequency of specific food consumption. Information on the onset of diseases and on different health-related aspects was collected every 2 years.

Those who consumed more red meat had a higher body mass index, higher total energy intake, and greater likelihood of being a smoker. They were physically less active and less likely to take multivitamins. In a follow-up of 5.48 million person-years, 22,761 cases of type 2 diabetes were recorded.

The link between consumption of processed and unprocessed red meat (and both combined) and a higher risk of diabetes was observed in all cohorts when analyzed separately and jointly. The people in the highest quintile for combined red meat consumption had a 2% greater risk of developing the disease, compared with those in the lowest quintile. The risk increases associated with processed and unprocessed meat were 51% and 40%, respectively. One additional serving per day of processed red meat was associated with a 1.46-fold greater risk of diabetes. This risk was 1.24 times greater for unprocessed meat and 1.28 times greater for both types combined.

The associations had a linear dose-response relationship and remained firm even after accounting for BMI, which the researchers stressed could be a mediating factor. Finally, the associations were stronger when considering the average cumulative consumption over the 30-year follow-up period and still stronger following the calibration of meat consumption with data extrapolated from food registers. The latter step was taken to account for measurement errors.
 

Alternatives are better

By analyzing alternative protein sources, the researchers discovered that nuts and legumes are associated with the most substantial reductions in diabetes risk. “This discovery is consistent with the evidence that shows that sources of unsaturated fatty acids and antioxidants have beneficial effects on glycemic control, insulin response, and inflammation,” they wrote. By replacing a serving of processed red meat, unprocessed red meat, or a combination of the two with a serving of dry fruit or legumes, the risk of developing diabetes is lowered by 30%, 41%, and 29%, respectively. Replacing red meat with a serving of dairy products is also associated with a reduced risk.

Confirmation

Several biological mechanisms could contribute to the increased risk for type 2 diabetes in people who consume red meat. The high level of saturated fats or the relatively low level of polyunsaturated fats, heme iron, or the high nitrate content in processed red meats could play a role. A strong positive association between consumption of this meat, particularly when processed, and the onset of diabetes has already emerged from other studies, including a trial carried out several years ago in the same cohorts. “In the current study, we wanted to look at this association in the same three cohorts in more detail, with over 9,000 additional cases of type 2 diabetes documented with extensive follow-up,” the researchers explained.

TOPLINE:

Tobacco users who quit smoking reduce their risk of developing type 2 diabetes by as much as 30% to 40%, and quitting even after one has developed type 2 diabetes is important in preventing a worsening of the disease’s many serious comorbidities, according to a new policy brief jointly issued by the World Health Organization, the International Diabetes Federation (IDF), and the University of Newcastle, Callaghan, Australia.

With type 2 diabetes representing one of the most prevalent chronic diseases worldwide and the ninth cause of death globally, the potential to reduce the risk and worsening of the disease by quitting smoking adds to the urgency of smoking cessation as a public health interest.
 

METHODOLOGY:

• The policy brief summarizes the evidence on the health impacts of type 2 diabetes, tobacco smoking, and the pathophysiology of tobacco use and its role in the development of type 2 diabetes.
• The brief also describes the latest data on newer products that target smokers or potential smokers, including smokeless tobacco, new nicotine and tobacco products, and their relationship with type 2 diabetes. For instance, evidence suggests that even with smokeless tobacco, heavy use or high consumption increases the risk of developing type 2 diabetes, as the products often contain nicotine, known to contribute to the development of type 2 diabetes and related health conditions.
• Evidence on the effectiveness of tobacco control interventions among those with type 2 diabetes is also summarized, including discussion of a systematic review of six studies suggesting that interventions focusing on education and the involvement of health care professionals and pharmacists can be beneficial for people with type 2 diabetes.

TAKEAWAY:

• Smoking exacerbates the known serious complications of diabetic neuropathy and foot ulcers with type 2 diabetes, while further impeding wound healing.
• Smoking also causes damage to retinal blood vessels already at risk with type 2 diabetes, increasing the risk of diabetic retinopathy and vision loss.
• Quitting tobacco use can help prevent those and other major health complications already linked to diabetes, including kidney failure and cardiovascular events.
• Studies show that key misconceptions among smokers with type 2 diabetes that can prevent cessation include concerns about post-cessation weight gain, the influence of peers who smoke, and the psychological aspect of addiction.
• Clinicians are urged to provide advice on how to stop smoking to all tobacco users during the course of a routine consultation or interaction, which can be accomplished in only a few minutes.

IN PRACTICE:

“Health professionals play a vital role in motivating and guiding individuals with type 2 diabetes in their journey to quit tobacco,” Ruediger Krech, MD, director of the Department of Health Promotion at the World Health Organization in Geneva, Switzerland, said in a press statement on the policy brief.

“Simultaneously, governments must take the crucial step of ensuring all indoor public places, workplaces, and public transport are completely smoke-free. These interventions are essential safeguards against the onset and progression of this and many other chronic diseases,” he emphasized.
 

SOURCE:

The policy brief was jointly developed by the World Health Organization, the International Diabetes Federation, and the University of Newcastle.

The detailed policy brief can be downloaded on the IDF website.
 

LIMITATIONS:

Research remains limited on some issues, including the effectiveness of tobacco control interventions and smoking cessation methods for people with type 2 diabetes.

Likewise, specific guidelines for smoking cessation in the type 2 diabetes population are lacking.  However, the general approaches of building patient motivation, behavioral interventions, and pharmacological treatments are advised.

“These interventions should be at least as intensive as those for the general population, while considering the unique characteristics of the disease and the individual,” the authors asserted.
 

DISCLOSURES:

The authors reported no relevant financial relationships.

TOPLINE:

Exposure to air pollutants is linked to emergency hospital admissions for stroke shortly after the exposure, with the risk being pronounced in men and individuals aged less than 65 years.

METHODOLOGY:

• Limited studies have investigated the association between hourly exposure to air pollutants and specific stroke subtypes, especially in regions with moderate to high levels of air pollution.
• The multicenter case-crossover study evaluated the association between hourly exposure to air pollution and stroke among 86,635 emergency admissions for stroke across 10 hospitals in 3 cities.
• Of 86,635 admissions, 79,478 were admitted for ischemic stroke, 3,122 for hemorrhagic stroke, and 4,035 for undetermined type of stroke.
• Hourly levels of fine particulate matter (PM2.5), respirable PM (PM10), nitrogen dioxide (NO2), and sulfur dioxide (SO2) were collected from the China National Environmental Monitoring Center.

TAKEAWAY:

• Exposure to NO2 and SO2 increased the risk for emergency admission for stroke shortly after exposure by 3.34% (95% confidence interval, 1.41%-5.31%) and 2.81% (95% CI, 1.15%-4.51%), respectively.
• Among men, exposure to PM2.5 and PM10 increased the risk for emergency admission for stroke by 3.40% (95% CI, 1.21%-5.64%) and 4.33% (95% CI, 2.18%-6.53%), respectively.
• Among patients aged less than 65 years, exposure to PM10 and NO2 increased the risk for emergency admissions for stroke shortly after exposure by 4.88% (95% CI, 2.29%-7.54%) and 5.59% (95% CI, 2.34%-8.93%), respectively.

TOPLINE:

Exposure to air pollutants is linked to emergency hospital admissions for stroke shortly after the exposure, with the risk being pronounced in men and individuals aged less than 65 years.

METHODOLOGY:

• Limited studies have investigated the association between hourly exposure to air pollutants and specific stroke subtypes, especially in regions with moderate to high levels of air pollution.
• The multicenter case-crossover study evaluated the association between hourly exposure to air pollution and stroke among 86,635 emergency admissions for stroke across 10 hospitals in 3 cities.
• Of 86,635 admissions, 79,478 were admitted for ischemic stroke, 3,122 for hemorrhagic stroke, and 4,035 for undetermined type of stroke.
• Hourly levels of fine particulate matter (PM2.5), respirable PM (PM10), nitrogen dioxide (NO2), and sulfur dioxide (SO2) were collected from the China National Environmental Monitoring Center.

TAKEAWAY:

• Exposure to NO2 and SO2 increased the risk for emergency admission for stroke shortly after exposure by 3.34% (95% confidence interval, 1.41%-5.31%) and 2.81% (95% CI, 1.15%-4.51%), respectively.

A patient with Parkinson’s disease (PD) can now walk with a normal gait without balance problems or fear of falling after implantation of a neuroprosthetic device.

The neuroprosthesis involves targeted epidural electrical stimulation of areas of the lumbosacral spinal cord that produce walking.

This new therapeutic tool offers hope to patients with PD and, combined with existing approaches, may alleviate a motor sign in PD for which there is currently “no real solution,” study investigator Eduardo Martin Moraud, PhD, who leads PD research at the Defitech Center for Interventional Neurotherapies (NeuroRestore), Lausanne, Switzerland, said in an interview.

“This is exciting for the many patients that develop gait deficits and experience frequent falls, who can only rely on physical therapy to try and minimize the consequences,” he added.

The findings were published online in Nature Medicine.
 

Personalized stimulation

About 90% of people with advanced PD experience gait and balance problems or freezing-of-gait episodes. These locomotor deficits typically don’t respond well to dopamine replacement therapy or deep brain stimulation (DBS) of the subthalamic nucleus, possibly because the neural origins of these motor problems involve brain circuits not related to dopamine, said Dr. Moraud.

Continuous electrical stimulation over the cervical or thoracic segments of the spinal cord reduces locomotor deficits in some people with PD, but the broader application of this strategy has led to variable and unsatisfying outcomes.

The new approach focuses on correcting abnormal activation of circuits in the lumbar spinal cord, a region that hosts all the neurons that control activation of the leg muscles used for walking.

The stimulating device is placed on the lumbar region of the spinal cord, which sends messages to leg muscles. It is wired to a small impulse generator implanted under the skin of the abdomen. Sensors placed in shoes align the stimulation to the patient’s movement.

The system can detect the beginning of a movement, immediately activate the appropriate electrode, and so facilitate the necessary movement, be that leg flexion, extension, or propulsion, said Dr. Moraud. “This allows for increased walking symmetry, reinforced balance, and increased length of steps.”

The concept of this neuroprosthesis is similar to that used to allow patients with a spinal cord injury (SCI) to walk. But unlike patients with SCI, those with PD can move their legs, indicating that there is a descending command from the brain that needs to interact with the stimulation of the spinal cord, and patients with PD can feel the stimulation.

“Both these elements imply that amplitudes of stimulation need to be much lower in PD than SCI, and that stimulation needs to be fully personalized in PD to synergistically interact with the descending commands from the brain.”

After fine-tuning this new neuroprosthesis in animal models, researchers implanted the device in a 62-year-old man with a 30-year history of PD who presented with severe gait impairments, including marked gait asymmetry, reduced stride length, and balance problems.
 

Gait restored to near normal

The patient had frequent freezing-of-gait episodes when turning and passing through narrow paths, which led to multiple falls a day. This was despite being treated with DBS and dopaminergic replacement therapies.

But after getting used to the neuroprosthesis, the patient now walks with a gait akin to that of people without PD.

“Our experience in the preclinical animal models and this first patient is that gait can be restored to an almost healthy level, but this, of course, may vary across patients, depending on the severity of their disease progression, and their other motor deficits,” said Dr. Moraud.

When the neuroprosthesis is turned on, freezing of gait nearly vanishes, both with and without DBS.

In addition, the neuroprosthesis augmented the impact of the patient’s rehabilitation program, which involved a variety of regular exercises, including walking on basic and complex terrains, navigating outdoors in community settings, balance training, and basic physical therapy.

Frequent use of the neuroprosthesis during gait rehabilitation also translated into “highly improved” quality of life as reported by the patient (and his wife), said Dr. Moraud.

The patient has now been using the neuroprosthesis about 8 hours a day for nearly 2 years, only switching it off when sitting for long periods of time or while sleeping.

“He regained the capacity to walk in complex or crowded environments such as shops, airports, or his own home, without falling,” said Dr. Moraud. “He went from falling five to six times per day to one or two [falls] every couple of weeks. He’s also much more confident. He can walk for many miles, run, and go on holidays, without the constant fear of falling and having related injuries.”

Dr. Moraud stressed that the device does not replace DBS, which is a “key therapy” that addresses other deficits in PD, such as rigidity or slowness of movement. “What we propose here is a fully complementary approach for the gait problems that are not well addressed by DBS.”

One of the next steps will be to evaluate the efficacy of this approach across a wider spectrum of patient profiles to fully define the best responders, said Dr. Moraud.
 

A ‘tour de force’

In a comment, Michael S. Okun, MD, director of the Norman Fixel Institute for Neurological Diseases, University of Florida, Gainesville, and medical director of the Parkinson’s Foundation, noted that the researchers used “a smarter device” than past approaches that failed to adequately address progressive walking challenges of patients with PD.

Although it’s “tempting to get excited” about the findings, it’s important to consider that the study included only one human subject and did not target circuits for both walking and balance, said Dr. Okun. “It’s possible that even if future studies revealed a benefit for walking, the device may or may not address falling.”

In an accompanying editorial, Aviv Mizrahi-Kliger, MD, PhD, department of neurology, University of California, San Francisco, and Karunesh Ganguly, MD, PhD, Neurology and Rehabilitation Service, San Francisco Veterans Affairs Health Care System, called the study an “impressive tour de force,” with data from the nonhuman primate model and the individual with PD “jointly” indicating that epidural electrical stimulation (EES) “is a very promising treatment for several aspects of gait, posture and balance impairments in PD.”

But although the effect in the single patient “is quite impressive,” the “next crucial step” is to test this approach in a larger cohort of patients, they said.

They noted the nonhuman model does not exhibit freezing of gait, “which precluded the ability to corroborate or further study the role of EES in alleviating this symptom of PD in an animal model.”

In addition, stimulation parameters in the patient with PD “had to rely on estimated normal activity patterns, owing to the inability to measure pre-disease patterns at the individual level,” they wrote.

The study received funding from the Defitech Foundation, ONWARD Medical, CAMS Innovation Fund for Medical Sciences, National Natural Science Foundation of China, Parkinson Schweiz Foundation, European Community’s Seventh Framework Program (NeuWalk), European Research Council, Wyss Center for Bio and Neuroengineering, Bertarelli Foundation, and Swiss National Science Foundation. Dr. Moraud and other study authors hold various patents or applications in relation to the present work. Dr. Mizrahi-Kliger has no relevant conflicts of interest; Dr. Ganguly has a patent for modulation of sensory inputs to improve motor recovery from stroke and has been a consultant to Cala Health.

People with diabetes had a 47% increased risk of getting colorectal cancer, compared with people without diabetes, according to results of a large new study. Getting a colonoscopy dramatically reduced the risk, the results showed.

The findings, published in JAMA Network Open, suggest that colonoscopies are particularly important for people with diabetes. People diagnosed with diabetes within the past 5 years have the greatest colorectal cancer risk, the study found, suggesting screening should be part of a person’s health care after they’re diagnosed with diabetes.

Researchers analyzed data for 54,597 people who contributed at least 2 years of health data as part of a study that recruited people from 12 Southeastern states between 2002 and 2009. The people self-reported their diabetes status, and although researchers tried to only include people with type 2 diabetes, it’s possible that some people in the study had type 1 diabetes. The average age of those in the study was 51 years old; 64% were women; more than half of them had an income of less than $15,000 per year; and 66% of them were African American. 

Among the people in the study who had diabetes, the risk of having colorectal cancer was not strongly impacted by their race or ethnicity, gender, weight, or income level, the study showed.

While race didn’t predict whether people with diabetes would get colorectal cancer, the findings are particularly important because most of the people in the study were African American. Diabetes and colorectal cancer disproportionately affect African American people, the authors noted. Medical research studies often struggle to recruit people of color, resulting in a lack of data to help guide health care priorities and decision-making.

The study also provided important guidance for people newly diagnosed with diabetes. People who were diagnosed with diabetes within the past 5 years were at a particularly increased risk of getting colorectal cancer, compared to people who had been diagnosed for 5-10 years.

The authors concluded that increased referrals for colonoscopies among people with diabetes, particularly among those newly diagnosed, could greatly reduce the impact of colorectal cancer. Current guidelines suggest most people should begin colorectal cancer screenings at age 45, according to the Centers for Disease Control and Prevention.

The study was supported by the National Cancer Institute and the University of Wisconsin, Madison. The study authors reported no relevant conflicts of interest.
