Climate change to drive multiple sclerosis cases, fuel treatment market: Report

Published

on

New Delhi, June 7 (IANS) Climate change is likely to have a significant impact on the rise in multiple sclerosis (MS) cases, increasing the need for effective approaches to treatment, according to a report on Friday.

Multiple sclerosis is an autoimmune disease of the central nervous system, which affects about 2.8 million people worldwide. The immune system attacks healthy nerve cells in an overreaction, causing them to continuously die.

The report by GlobalData, a data and analytics company, aligned with a June 2024 literature review, published in the Lancet Neurology, which revealed that climate change has the potential to intensify MS symptoms.

The report anticipates an uptick in the prevalence and disease severity of MS, and the need for newer and more effective approaches to treatment arises.

The main treatments for MS focus on slowing the disease’s progression and are disease-modifying therapies (DMTs).

The report forecasts that sales for MS DMTs will grow to $30.1 billion by 2030, at a compound annual growth rate (CAGR) of 4.7 per cent during 2020 -30.

“Climate change-related exacerbations of MS will necessitate the development of novel, more effective DMTs as disease flare-ups become more frequent with fluctuating temperatures,” said Jos Opdenakker, Pharma Analyst at GlobalData.

Currently, there are two ongoing Phase III clinical trials in which Novartis’s remibrutinib and Genentech’s fenebrutinib are being evaluated in comparison to the presently available standard of care — Sanofi’s Aubagio (teriflunomide) in patients with relapsing MS.

“These trials signify pharmaceutical companies’ interest in developing more effective DMTs, as the severity of MS symptoms is getting magnified due to climate change, a potential driver of growth in the MS market,” Opdenakker said.

While research is being conducted and new health policies are under development, more effective DMTs have the potential to occupy the interlude as the main line of defence for MS patients against climate change.

Opdenakker stressed the need for “new and more effective therapeutic interventions to form an all-encompassing, coherent strategy for managing MS in line with climate change”.

Older adults likely to continue using wearable tech if get aid from healthcare peers: Study

Published

on

By

New Delhi, June 22 (IANS) Older adults living in the community are more likely to continue using Wearable Monitoring Devices (WMDs), such as trackers, pedometers, and smartwatches, if they get support from healthcare professionals or peers, a new study has found.

In the study published in the Journal of Medical Internet Research, the researchers from The Hong Kong Polytechnic University studied data from three randomised controlled trials involving over 150 older adults.

“Healthcare professionals play a pivotal role in facilitating the adoption of wearable monitoring devices among older adults,” said Dr Arkers Kwan Ching Wong, who led the research.

The data indicated that interventions focused on increasing awareness of monitoring and utilising collaborative goal-setting and feedback tools, such as the SystemCHANGE approach, improved adherence to WMDs.

WMDs can offer helpful health insights, but their long-term use can be challenging for older adults who may not be comfortable with technology or do not see the value in using it, the researchers noted.

However, the research highlighted that providing targeted support to assist older adults overcome these barriers and integrate WMDs into their daily routines can help maximise the potential health benefits of these devices.

“By working with healthcare professionals to set specific goals related to the use of wearables, older adults are more likely to benefit from these devices in the long term,” the researchers said.

Researchers use diabetes medication as effective drug therapy for sleep-related disorder

Published

on

By

London, June 22 (IANS) A team of researchers have demonstrated the potential of tirzepatide, known to manage type 2 diabetes, as the first effective drug therapy for Obstructive Sleep Apnea (OSA), a sleep-related condition characterised by repeated episodes of irregular breathing due to complete or partial blockage of the upper airway, a new study has said.

The study published in the New England Journal of Medicine highlighted the treatment’s potential to enhance the quality of life for millions worldwide affected by OSA.

“This study marks a significant milestone in the treatment of OSA, offering a promising new therapeutic option that addresses both respiratory and metabolic complications,” said Atul Malhotra, MD, lead author of the study, professor at UC San Diego Health.

OSA can cause low blood oxygen levels and raise the risk of cardiovascular problems such as hypertension and heart failure. Recent research, also led by Malhotra, suggests that there are approximately 936 million OSA patients globally.

The study involved 469 participants diagnosed with clinical obesity and living with moderate-to-severe OSA.

The participants were administered either 10 or 15 mg of the drug by injection or a placebo. The impact of tirzepatide was assessed over 52 weeks.

Researchers found that tirzepatide led to a significant drop in the number of breathing interruptions during sleep, a key indicator used to measure the severity of OSA.

“This improvement was much greater than what was seen in participants that were given a placebo,” the study mentioned.

In addition, the researchers noted that some participants who took the drug reached a point where CPAP therapy might not be necessary.

The therapy also improved other factors related to OSA, such as reducing the risk factors of cardiovascular diseases and improving body weight.

“This new drug treatment offers a more accessible alternative for individuals who cannot tolerate or adhere to existing therapies. We believe that the combination of CPAP therapy with weight loss will be optimal for improving cardiometabolic risk and symptoms,” said Malhotra.

Weight loss linked with reduced cancer risk in people with obesity: Study

Published

on

By

San Francisco, June 22 (IANS) Real-world weight loss is linked with a decreased risk of obesity-related cancers, a new study has said.

The study published in the journal American Diabetes Association comprised 172 patients including 100,143 in the control arm and 5,329 cases.

The median body mass index (BMI at censoring (kg/m2.) was 34.2 for cases and 34.5 for controls, which are considered to have obesity according to the US-based Centers for Disease Control and Prevention (CDC).

For each cancer endpoint, logistic regression models were used to assess the association of body mass index (BMI) change with three, five, and 10-year intervals before cancer diagnosis (for cases) versus controls.

The study found that the risk was reduced for renal cell carcinoma (three years), multiple myeloma (10 years), and endometrial cancer (three and five years) among primary cancer endpoints.

“This study reinforces how crucial it is to treat obesity as a chronic disease,” said Kenda Alkwatli, MD, Clinical Fellow at Cleveland Clinic, and author of the study.

“We are hopeful that these results can help us better understand how we can use weight loss to address comorbidities including cancer in patients with obesity,” she added.

As per the researchers, obesity is linked to higher risks of at least 13 types of cancer due to excess estrogen and elevated insulin, including breast, kidney, ovary, liver, and pancreatic cancer.

Bird flu outbreak at US dairy farms cause public health concerns

Published

on

By

Los Angeles, June 22 (IANS) The ongoing bird flu outbreak at US dairy farms has heightened concerns among public health experts as more dairy herds have tested positive for the virus in recent months.

The influenza A (H5N1) virus, commonly known as bird flu, is widespread in wild birds worldwide and has been circulating in US poultry since 2022, reports Xinhua news agency.

However, the situation escalated in late 2023 when the virus is believed to have jumped from birds to dairy cows at a Texas farm.

This was followed by a human infection in April linked to exposure to infected cattle. To date, three human cases of infection have been reported, bringing the total number of US H5N1 cases to four, including one case in 2022 linked to poultry exposure, according to the Centers for Disease Control and Prevention (CDC).

The virus had been confirmed in at least 115 dairy herds across 12 states as of Thursday, according to the latest tally posted on the US Department of Agriculture’s Animal and Plant Health Inspection Service website.

In a new study funded by the National Institutes of Health (NIH), researchers found “small, detectable amounts of infectious (H5N1) virus remained in raw milk samples with high virus levels” when treated at 72 degrees Celsius for 15 seconds — one of the standard pasteurisation methods used by the dairy industry, according to an NIH press release last week.

The CDC noted that while the current public health risk is low, it is watching the situation carefully and working with states to monitor people with animal exposures.

But public health experts have paid attention to the government’s slow response and inadequate testing.

“Failures in testing continued. This was a serious problem in the early months of COVID-19, in mpox, and now with H5N1. There will be future disease emergencies — we have to do better,” wrote Gigi Gronvall, an immunologist, on social media X on Thursday.

Gronvall, an associate professor at Johns Hopkins Bloomberg School of Public Health, called for a public-private partnership between the government, test developers, and clinical laboratories to streamline testing rollout and information sharing at the beginning of an event.

The World Health Organization considers bird flu a public health concern, as these viruses, including the H5N1 strain, can result in mild to severe illness and death and have the potential to mutate to become more contagious, says the organisation on its website.

While infections have been confirmed in cattle across the country, only 45 individuals have been tested for novel influenza A since March, with 550 under monitoring, according to the CDC’s latest update on June 14.

Aside from the limited availability of bird flu tests, experts said the low trust of farm owners and farm workers towards the government also makes it difficult to detect potential cases.

“The United States’ response to H5N1 — ‘bird flu’ — has taken too long, showing how risky gaps in coordination and trust can be,” wrote Tom Frieden, former director of the CDC, in an analysis published by CNN on Tuesday.

“Trust toward the United States government is low, especially among rural Americans who are on the front line of these outbreaks,” added Frieden, president and chief executive of Resolve to Save Lives.

Many dairy farm workers in the United States are undocumented immigrants or migrants who may distrust the government or be hesitant to miss work if they test positive, CDC Principal Deputy Director Nirav Shah told Axios in a Tuesday report.

Despite the allocation of federal funds to incentivise farm cooperation, no farms have enrolled in the voluntary on-site milk testing program, according to the US Department of Agriculture.
