Recent research, published in The American Journal of Pathology, using a mouse model has found that treatment with vitamin A may significantly improve eyesight in those suffering from type 2 diabetes.
Researchers checked the effectiveness of the chromophore 9-cis-retinal in the treatment of vision loss in mice with diabetes. They used 9-cis-retinal instead of 11-cis-retinal produced by the body because the latter is highly unstable and not commercially available but they are closely related.
In the study, the mice with diabetes were divided into two groups, one of which received an injection of a single dose of 9-cis-retinal, while another group received a placebo. The analysis of the results showed that the mice that received treatment with 9-cis-retinal had significantly improved vision across all measures.
Lead researcher Dr. Gennadiy Moiseyev, from the University of Oklahoma Health Sciences Center in Oklahoma City, says: “This study suggests that the delivery of visual chromophore to the diabetic eye may represent a potential therapeutic strategy for the early stages of diabetic retinopathy to prevent vision loss in [people] with diabetes.”
A large international study finds that a high intake of whole-fat dairy products is associated with a lower risk of hypertension (high blood pressure) and diabetes.
For the study, a team of researchers analyzed data taken from 147,812 people who live in Asia, North and South America, Africa, and Europe. The participants were 35 to 70 years old. To gather the necessary information, the questionnaires were used.
The analysis showed that people who had at least 2 servings of dairy or 2 servings of whole fat dairy per day had a 24% and a 28% lower risk of metabolic syndrome than people who ate no dairy at all.
Study co-author Andrew Mente, Ph.D., a principal investigator at the Population Health Research Institute, in Hamilton, Canada, says: “Higher intake of dairy foods, such as milk, yogurt, and cheese, especially whole-fat dairy rather than low-fat dairy, is associated with a lower prevalence of metabolic syndrome and with a lower risk of developing hypertension and diabetes.”
New research from France suggests that ultra-processed foods such as sugary drinks, packaged snacks, and ready-made meals, can increase the risk of developing type 2 diabetes.
To examine the effect of this kind of food, containing a higher number of additives and preservatives, a team of researchers conducted a study in which they included 104,707 adult participants, 21,800 men and 82,907 women, who had taken part in the NutriNet-Santé study.
The study has been performed from 2009 to 2019 and during this period the researchers gathered data on the dietary intake of the participants using 24-h dietary records containing information on around 3,500 foods.
Having analyzed the available data, the researchers found a consistent link between the absolute amount of ultra-processed food consumption and the risk of type 2 diabetes.
The researchers write in their paper: “Even though these results need to be confirmed in other populations and settings, they provide evidence to support efforts by public health authorities to recommend limiting [ultra-processed food] consumption.”
A new study, published in the Diabetologia, finds that children who were born prematurely have a higher risk of developing diabetes, type 1 or type 2, later in life.
To perform the analysis, the researchers used information from the Swedish Birth Registry that included data on more than 4 million people. Preterm birth was considered as birth occurring at less than 37 gestational weeks. In total, 4,193,069 Swedes were included in the investigation.
Researchers write in their paper: “Because of major advances in treatment, most preterm infants now survive into adulthood. As a result, clinicians will increasingly encounter adult patients who were born prematurely. Preterm birth should now be recognized as a chronic condition that predisposes to the development of diabetes across the life course.”
According to a recent study from the University of Cambridge, the United Kingdom, people who achieve moderate weight loss within the first few years after the diagnosis of type 2 diabetes, may reverse the condition.
For the study, a team of scientists analyzed data from 867 people aged from 40 to 69 who were diagnosed with type 2 diabetes recently. The researchers followed the participant for 5 years. They found that those participants who had achieved at least 10% weight loss within 5 years had more than twice likely to send the condition into remission than those who had not lost any weight.
The first author of the study Hajira Dambha-Miller, Ph.D., says: “These interventions can be very challenging to individuals and difficult to achieve. But, our results suggest that it may be possible to get rid of diabetes, for at least 5 years, with a more modest weight loss of 10%. This will be more motivating and hence more achievable for many people.”
