The University of South Australia has made a groundbreaking discovery that could revolutionize the treatment of Parkinson’s disease. Scientists have developed a long-acting injectable formulation that delivers a steady dose of levodopa and carbidopa over an entire week, potentially replacing the need for multiple daily tablets.

Parkinson’s disease is the second most common neurological disorder, affecting more than 8.5 million people worldwide. Currently, there is no cure, and symptoms such as tremors, rigidity, and slow movement are managed with oral medications that must be taken several times a day. The frequent dosing can be a burden, especially for elderly patients or those with swallowing difficulties, leading to inconsistent medication levels, more side effects, and reduced effectiveness.

The newly developed injectable gel combines an FDA-approved biodegradable polymer PLGA with Eudragit L-100, a pH-sensitive polymer, to achieve a controlled and sustained drug release. The system can be tuned to release drugs over a period ranging from a few days to several weeks depending on therapeutic needs.

Lead researcher Professor Sanjay Garg says the weekly injection could significantly improve treatment outcomes and patient adherence. “Our goal was to create a formulation that simplifies treatment, improves patient compliance, and maintains consistent therapeutic levels of medication. This weekly injection could be a game-changer for Parkinson’s care.”

UniSA PhD student Deepa Nakmode adds, “After years of focused research, it’s incredibly rewarding to see our innovation in long-acting injectables for Parkinson’s disease reach this stage. Our invention has now been filed for an Australian patent.”

The implications of this research are profound, and the technology could also be adapted for other chronic conditions such as cancer, diabetes, neurodegenerative disorders, pain management, and chronic infections that require long-term drug delivery.

UniSA scientists hope to start clinical trials in the near future and are exploring commercialisation opportunities. With this breakthrough, patients with Parkinson’s disease may soon have a more convenient and effective treatment option available, leading to improved quality of life and reduced burden on caregivers.

The article reveals a surprising truth: high blood sugar levels can have a significant impact on men’s sexual health, even if they are not diabetic. A recent study presented at the Endocrine Society’s annual meeting in San Francisco found that modest increases in blood sugar were the primary drivers of changes in the reproductive systems and sexual functioning of aging men.

According to Dr. Michael Zitzmann, professor and doctor of medicine at University Hospital in Muenster, Germany, “Our research indicates that these changes more closely correlate with modest increases in blood sugar and other metabolic changes.” This means that men can take proactive steps to preserve or revive their reproductive health through lifestyle choices and medical interventions.

The study followed a group of 200 healthy men aged 18-85 over six years. Researchers studied the participants’ semen and hormonal profiles, erectile functioning, and metabolic health (BMI and blood sugar levels). The findings showed that:

* Hormone levels and semen parameters remained largely within normal ranges.
* Sperm movement and erectile function declined in men with minimally elevated blood sugar levels (below 6.5% HbA1c diabetes threshold).
* Testosterone levels did not directly impact erectile function but correlated with participants’ libido assessment.

The study’s conclusions are hopeful: “We’re now aware that it’s within our power to retain sexual and reproductive well-being in men, even as they age.” This research was conducted as part of the FAME 2.0 study, providing valuable insights for healthcare professionals and patients to formulate effective male sexual health maintenance plans.

A groundbreaking study has revealed that combining menopause hormone therapy with the obesity medication tirzepatide can lead to significantly greater weight loss in postmenopausal women. The research, presented at the Endocrine Society’s annual meeting, provides new insights into how these two treatments can be used together to improve the health and well-being of millions of women.

Menopause-related hormonal changes often result in increased abdominal fat, decreased muscle mass, and altered energy expenditure, leading to weight gain and an increased risk of heart disease and other serious health issues. To confirm the hypothesis that concurrent menopause hormone therapy enhances the effectiveness of tirzepatide for weight loss, researchers conducted a real-world study using the electronic medical records of 120 postmenopausal women over a median duration of 18 months.

The results were striking: superior total body weight loss percentage was observed in women using tirzepatide plus menopause hormone therapy (17%) compared to those using tirzepatide alone (14%). Moreover, a higher percentage of menopause hormone therapy users (45%) achieved at least 20% total body weight loss, compared to 18% of menopause hormone therapy non-users.

These findings have significant implications for the development of more effective and personalized weight management interventions to reduce the risk of overweight and obesity-related health complications in postmenopausal women. As one researcher noted, “This study underscores the urgent need for further research to better understand how obesity medications and menopause hormone therapy work together. Gaining this knowledge could greatly improve the health and well-being of millions of postmenopausal women.”

The study was funded by the National Institutes of Health Bridging Interdisciplinary Careers in Women’s Health Research Grant and the Mayo Clinic Center for Women’s Health Research, highlighting the importance of continued investment in research that addresses the unique needs of women’s health.
