Breakthrough in wound healing, electric suture creates excitement

A new type of suture that combines electrical stimulation with traditional suturing methods has been developed.

It has been demonstrated that this mechanoelectric suture, which is constructed from biodegradable materials and generates electric fields in response to movement, significantly accelerates wound healing and lowers the risk of infection.

This innovative approach could revolutionise wound closure procedures and offer patients a faster and safer healing process.

In an experiment in rats, the new strong, flexible thread hastened wound healing by transforming muscle movement into electricity, researchers report in Nature Communications.

According to materials scientist Chengyi Hou of Shanghai’s Donghua University, the substance “could change how we treat injuries” if it is finally shown to be safe for use in humans.

Although prior methods depended on large external batteries, researchers already knew that applying electricity to sutures helped accelerate the healing process. The body provides the energy for the new sutures.

The thread is composed of magnesium, a metal that the body may eventually absorb, and biodegradable polymers. The central layer of the thread rubs against the outer shell when the muscles around the sutures contract and relax, which transfers electrons to the shell and produces electricity.

Hou and colleagues used the thread’s electrical stimulation to treat artificial wounds in lab dishes. After 24 hours, fibroblasts, which are critical to healing, reduced the wound area from 69 percent to 11 percent. Untreated artificial wounds reduced in size from 69 percent to 33 percent after 24 hours.

Rodents treated with electrical sutures recovered faster and were less likely to acquire infections than rats treated with regular sutures or left untreated. Next, the team intends to try the sutures on bigger animals.

NAFDAC destroys N5bn fake, expired products in Aba

The National Agency for Food and Drug Administration and Control (NAFDAC) has shut down 150 shops at Eziukwu Market in Abia over fake and expired products Worth N5 billion.

The agency disclosed this in a statement on Wednesday on X.

NAFDAC said the shops were shut during a two-day operation on December 16 and 17, while products valued at N5billion were destroyed at the market.

The director of the South-East zone, Martins Iluyomade, expressed dismay at the continued illegal activities despite a previous undertaking signed by market leaders in December 2023 to expose counterfeiters.

According to the statement, Mr Iluyomade described the market as a hub for counterfeit and substandard products.

“Our team uncovered a large-scale production and distribution of fake and expired goods, including beverages, carbonated drinks, wines, spirits, and vegetable oils.

“Revalidated food items such as milk, yoghurt, noodles among others were also destroyed,” the statement said.

It reaffirmed NAFDAC zero tolerance for such practices and emphasised its unwavering commitment to safeguarding public health while working toward a permanent solution to the problem of counterfeiting in the market

Eating fish regularly minimises risk of incurable hearing condition – Study

Eating fish regularly minimises risk of incurable hearing condition – Study

Tinnitus is the sound of ringing in the ears. It may also be described as roaring, buzzing, hissing, or clicking inside the head. The sounds may come and go. Or they may be ongoing. The sounds range in severity from a mild distraction to a disabling condition and may manifest with buzzing, hissing, or clicking inside the head.

The sound may happen in one or both ears and may have different tones. A team from Brigham and Women’s Hospital in Boston studied 73,000 individuals to understand how common this disorder is, which affects millions  with a constant ringing in their ears.

Over a span of 30 years, those who consumed more than two servings of fish weekly had nearly 25 percent lower odds of getting tinnitus compared to those who seldom or never ate fish. Even eating just one serving a week resulted in a 13 percent reduced risk.

Certain types of fish, like tuna, light-fleshed varieties such as cod or halibut, and shellfish, were linked to a reduced risk, while darker fish like salmon and swordfish seemed to increase the risk.

Interestingly, fish oil supplements, known for their benefits to heart, brain, and joint health, were also connected to a higher risk of tinnitus. It’s estimated that tinnitus is diagnosed in almost 1 in 6 persons.

While age-related hearing loss, ear injuries, and circulation issues are known to contribute to tinnitus, the exact cause remains unclear. Previous studies have suggested that dietary factors, such as high levels of calcium, iron, and fat, might heighten the risk. However, this new research is the first to analyse data over such a lengthy period.

Past findings have also shown that seafood can lower the risk of hearing loss, with one study suggesting that increased fish consumption might reduce hearing issues by up to 20 percent. Scientists believe that the omega-3 fatty acids in fish could protect inner ear cells or reduce inflammation caused by loud sounds, chemicals, or infections.

The Boston team’s investigation, based on a database of US nurses, aims to shed light on the connection between fish consumption and tinnitus, potentially aiding future patients. The authors of the study expressed hope that identifying factors that can be changed might help in preventing tinnitus and guiding targeted treatments.

Nigerian doctor claims increased s3xual activity lowers cancer risk for women

Nigerian doctor claims increased s3xual activity lowers cancer risk for women

Dr. Rasheed Abassi, a Nigerian medical practitioner, has sparked widespread debate following comments on TVC’s programme Your View, where he recommended increased sexual activity for women as a way to reduce the risk of breast cancer.

The doctor also advised men to consider polygamy, citing its potential health benefits, including a lower risk of prostate cancer.

“Women need to have more sex to reduce breast cancer risk. When a woman reaches orgasm, she releases oxytocin, which lowers her chances of developing cancer,” Dr. Abassi stated during the interview.

Addressing men’s health, Dr. Abassi claimed that polygamy could improve longevity and reduce prostate issues. “Men with two to three wives live longer than men with one wife. If your son is not getting rid of his DHT (dihydrotestosterone), he is likely to develop an enlarged prostate,” he said.

He also linked the absence of regular erections to potential cardiac problems. “Any man not waking with a full erection already has cardiac issues. My oldest patient is 92 years old and has a four-year-old daughter — and that’s DNA-proven,” he revealed.

When asked about the risks of sexually transmitted infections (STIs) associated with increased sexual activity, Dr. Abassi emphasised the importance of safe practices. “The condom is not 100% protective, but we still advise it. Awareness is key,” he said.

He also noted that some men cite the cost of contraceptives as a challenge, comparing it to the financial costs of engaging in sexual activities.
