Breast implants have a positive impact on female sexuality, according to new research

Women tend to report improved sexual functioning after undergoing breast augmentation surgery, according to new research published in Revista da Associacao Medica Brasileira. The findings suggest that this popular cosmetic procedure not only enhances physical appearance but also positively impacts women’s self-confidence.

Breasts hold a central role in how society perceives femininity, sexuality, and maternity. Changes in breast size, shape, or distortions can have a profound effect on a woman’s self-image and quality of life. Dissatisfaction with one’s body, including breast size and contour, can lead to sexual dysfunction and reduced quality of life.

“Breast augmentation is on of the most performed procedures in plastic surgery and it is due to the impact that it causes on women’s life quality and self-esteem,” said study author Mateus Leme De Marchi, a plastic surgery resident in São Paulo, Brazil.

The study involved 87 women with hypomastia (small breasts) who desired breast augmentation. The criteria for inclusion encompassed women between 18 and 55 years old, a minimum education level of the 5th grade, and small breast size according to the Sacchini index. Exclusion criteria included factors such as pregnancy, systemic diseases, smoking, and previous breast surgeries.

Two groups of patients were assessed using separate questionnaires. The Female Sexual Quotient (QS-F) questionnaire was used in one group, and the Female Sexual Function Index (FSFI) questionnaire in the other. The surgical procedure involved placing subglandular silicone implants, adhering to strict protocols and safety measures.

Patients completed their respective questionnaires before the surgery and at follow-up visits, two and four months after the procedure. The questionnaires evaluated various aspects of sexual function, including desire, arousal, lubrication, pain, orgasm, and satisfaction.

In the QS-F group, patients showed an initial slight decrease in scores at two months postoperatively, likely due to discomfort and pain following surgery. However, at the four-month mark, there was a significant increase in scores, indicating an improvement in their sexuality.

Similarly, the FSFI group also demonstrated improvements in sexual function, with scores increasing from preoperative levels to two and four months postoperatively.

“I was surprised with the improvement in sexuality only a couple months after surgery, when people still haven’t completed all the healing process,” De Marchi said.

One notable finding was the significant improvement in the domain of arousal and harmony with a partner in both groups. This suggests that breast augmentation positively influenced women’s self-confidence, self-esteem, and overall satisfaction with their body image, subsequently enhancing their sexual desire and arousal.

The results of this study underscore the close connection between a woman’s breasts and her self-image, body satisfaction, and ultimately, her sexuality. Changes in breast size and shape, brought about by augmentation, can lead to significant improvements in various aspects of a woman’s quality of life, including her sexual well-being.

“Breast augmentation has a positive impact on life quality, which encompasses sexuality,” De Marchi told PsyPost. “Some women maybe don’t feel very comfortable with their bodies and specifically their breasts, either because of the standards of beauty and size proposed by social media or because of bullying. This may cause many prejudices in their life and self-esteem. For these women, the breast augmentation brings high satisfaction and can improve the relationship of the woman and her own body, which can bring a big benefit in her sexuality.”

While this study provides valuable insights into the impact of breast augmentation on female sexuality, it is essential to acknowledge its limitations. The study was conducted at a single center and had a relatively small sample size. Additionally, the follow-up period was relatively short at 4 months post-surgery.

Future research should aim to include larger and more diverse study populations, as well as longer-term follow-up assessments, to gain a more comprehensive understanding of the long-term effects of breast augmentation on female sexuality.

“We studied the sexuality, which is part of life quality, but we could see an improvement in other aspects of life quality as well, which must be studied,” De Marchi added.

The study, “Impact of breast augmentation on female sexuality“, was authored by Paulo Afonso Monteiro Pacheco Guimarães, Elisa Mayumi Kokuba Aihara, Miguel Sabino Neto, Mateus Leme De Marchi, and Lydia Masako Ferreira.

New engineered bacteria could destroy plastics in seawater

Over 14 million tons of plastic litter ends up in the ocean every year, killing thousands of animals and birds that ingest it. Much of it ends up amassing in giant garbage patches and over time breaking down into smaller microscopic pieces that are harmful to marine life.

A new study offers a glimmer of hope in addressing this marine plastic pollution problem. Researchers at North Carolina State University report in the AIChE Journal that they have genetically engineered a marine microorganism to break down a commonly used plastic in salt water.

Polyethylene terephthalate (PET) is a type of plastic used to make bottles, food packaging and clothes. Much PET plastic waste does not get recycled, and ends up in landfills and aquatic environments. It eventually breaks down into microplastics—particles with a size of less than 5 mm—which are challenging to collect and have been shown to move quickly between aquatic, terrestrial, and atmospheric environments, the researchers point out in the paper.

Some microbes have been found to have the ability to break down plastic. Researchers have genetically engineered bacteria, or even just the enzymes they produce, to convert plastic waste into valuable chemicals. A key limitation with these previously modified organisms is that “their growth is inhibited by high concentrations of salt,” the NCSU team writes. That means microplastics would have to be collected and washed off using large quantities of water before they can be broken down.

So the researchers took a different approach, harnessing two different species of bacteria. The first, Vibrio natriegens, lives in saltwater and reproduces very quickly, doubling in number in under 10 minutes in ideal conditions. The second bacteria, Ideonella sakaiensis, produces enzymes that can deconstruct PET.

The team isolated the DNA sequence from I. sakaiensis that is responsible for producing the enzyme, and inserted it into V. natriegens. The modified V. natriegens could produce the PET-degrading enzymes on the surface of their cells. They found that V. natriegens was able to break down PET into its building blocks in a saltwater environment at room temperature.

“From a practical standpoint, this is the first genetically engineered organism that we know of that is capable of breaking down PET microplastics in saltwater,” said Tianyu Li, a PhD student and the paper’s first author, in a press release. “That’s important, because it is not economically feasible to remove plastics from the ocean and rinse high concentration salts off before beginning any processes related to breaking the plastic down.”

There is still significant work to be done, the researchers say. They now plan to modify V. natriegens so that it can feed on the byproducts it creates when it breaks apart PET, and so it can produce useful chemical molecules in the end.

Child drug poisonings and firearm deaths have skyrocketed in America: Study

Firearm deaths and drug poisoning deaths in children have spiked in the last decade, according to a new study in the United States. The study found an increase in firearm deaths by 87% and drug poisoning deaths by 133%.

Researchers looked at data from the Centers of Disease Control and Prevention’s injury reporting system. They analyzed injuries leading to death from 2011-2021 and nonfatal injuries from 2011-2020.

Overall, they found that fatal injury rates increased from about 14 deaths per 100,000 children in 2011 to over 17 deaths per 100,000 children in 2021. Firearm injuries made up the biggest portion of those fatal injuries.

Both the increase in firearm and drug overdoses may be because children can get ahold of these dangerous items easily, says Dr. Rebecca Mannix, an author on the study and a pediatric emergency medicine physician at Boston Children’s Hospital.

"The access issues of firearms and prescription and illicit drugs have also been a huge problem in the pediatric population," she says. "There's a reservoir of both prescribed and illicit drugs that kids have access to that can become quite deadly."

The study found that pediatric injury fatalities sharply increased in the pandemic years of 2020 to 2021.

"The increase in pediatric injury-related deaths preceded the COVID-19 pandemic, though the pandemic exacerbated numerous factors underlying this disturbing trend, including access to lethal means, such as firearms and opioids, the mental health crisis and structural racism," said Mannix in an email to ABC News. "In this way, the increase in deaths in 2020 to 2021 is an amplified trend that has been creeping up on us for the last decade."

It remains unclear whether these trends will continue. The study also looked at the trends of injuries that did not lead to death in children.

Nonfatal injuries decreased by more than half between 2011 and 2020. Motor vehicle injuries saw a decrease by 47%.

While it is hard to determine why there was a decrease, Mannix and her team point to public health initiatives, such as booster seats for children, as a possible cause.

"This is largely due to public health interventions I think, in the last few decades, improving motor vehicle safety, improving helmet technology, [and] childproofing," says Mannix. Technological advancements and legislative requirements may also have contributed, experts say.

Public safety initiatives are key to keeping children safe, says Dr. Wee Chua, a pediatric emergency medicine physician at Massachusetts General Hospital and Harvard University. That includes "car seats, bike helmets, and the safe storage of firearms," Chua says.

Despite overall decreases in nonfatal injuries, the rates of self-harm increased by 57%. Self-harm is the act of purposefully hurting oneself, and it’s associated with mental illnesses like depression and anxiety.

"I spend my clinical time in the ER," says Mannix, "And I can tell you, there's a behavioral health [and] mental health crisis in kids."

Parents can prevent firearm injuries and drug poisonings by removing guns from homes, locking prescription drugs, monitoring for illicit and prescription drug use and seeing a doctor if your child is exhibiting self-harm behavior.

AI translates 5,000-year-old cuneiform tablets into English | A new technology meets old languages.

Abstract

Cuneiform is one of the earliest writing systems in recorded human history (ca. 3,400 BCE–75 CE). Hundreds of thousands of such texts were found over the last two centuries, most of which are written in Sumerian and Akkadian. We show the high potential in assisting scholars and interested laypeople alike, by using natural language processing (NLP) methods such as convolutional neural networks (CNN), to automatically translate Akkadian from cuneiform Unicode glyphs directly to English (C2E) and from transliteration to English (T2E). We show that high-quality translations can be obtained when translating directly from cuneiform to English, as we get 36.52 and 37.47 Best Bilingual Evaluation Understudy 4 (BLEU4) scores for C2E and T2E, respectively. For C2E, our model is better than the translation memory baseline in 9.43, and for T2E, the difference is even higher and stands at 13.96. The model achieves best results in short- and medium-length sentences (c. 118 or less characters). As the number of digitized texts grows, the model can be improved by further training as part of a human-in-the-loop system which corrects the results.

Significance Statement

Hundreds of thousands of clay tablets inscribed in the cuneiform script document the political, social, economic, and scientific history of ancient Mesopotamia. Yet, most of these documents remain untranslated and inaccessible due to their sheer number and limited quantity of experts able to read them. This paper presents a state of the art neural machine translation model for the automatic translation of Akkadian texts into English, from Unicode cuneiform glyphs and from transliterations of the cuneiform signs, achieving 36.52 and 37.47 Best Bilingual Evaluation Understudy 4 (BLEU4) scores, respectively. It is particularly effective in maintaining the style of the text genre in the translation. This is another major step toward the preservation and dissemination of the cultural heritage of ancient Mesopotamia.

What are possible specialities in power system engineering?

As a newly graduate with Power Engineering degree, what speciality in power systems should you focus on?

I will give you some insights, these inputs will help you decide in the type of learning course and projects you will pursue in power system speciality.

You have a couple of paths to take:

1. System Protection (relays and settings)

2. System Control (generator control, remedial action schemes, etc.)

3. System Design (create prints, bill of materials, etc.)

4. System Testing (in service testing and commissioning or equipment testing)

5. System Studies (powerflow, voltage and transient stability studies, planning, etc)

6. Project Engineer (a smarter PM)

What you do depends on what type of career you want. Every power system company has system protection, plenty of positions, and is an extremely deep topic so it is always a good choice.

Controls is very specific to a particular company so the skills aren’t always marketable to other companies but if you want to stay long term in one place this is a great path because they always need you.

Design is pretty much only contract work these days. You can work for a firm but you will get overworked and underpaid.

System testing is some of the most fun but you will have to travel 90% of the time which is a hard lifestyle but some people love it. Very nomadic. 

System studies is a good choice if you are computer inclined. You essentially need a good understanding of the power system and some computer science to be really successful. This path gets you into a lot more theoretical stuff and lots of companies are doing hybrid or full remote positions if that attracts you. 

Project engineers are in meetings all day. You lose a lot of the technical side but you get your face in front of management if you do a good job so it can help you move into management if that is your goal.

Calls for verbal abuse of children by adults to be formally recognised as form of child maltreatment

A new systematic review by researchers at UCL and Wingate University has highlighted the importance of identifying childhood verbal abuse by adults as a standalone subtype of child maltreatment, to ensure targeted prevention and address the lasting harm it can inflict.

Child maltreatment is currently classified into four subtypes: physical abuse, sexual abuse, emotional abuse, and neglect. These classifications guide the creation of interventions and the monitoring of affected populations.

The study, published in Child Abuse & Neglect: The International Journal and commissioned by charity, Words Matter, examines a total of 149 quantitative and 17 qualitative studies to assess how child verbal abuse is currently defined and measured.

Researchers found that there needs to be a more consistent way of defining childhood verbal abuse, as it currently varies between parents and other authorities, with it being normalised in some cultures as a form of discipline.

The nature of childhood verbal abuse involves behaviours that can be detrimental to a child’s wellbeing, such as belittling, shouting, and threatening language.

It was found that these actions could have a lasting impact throughout the child’s life, creating underlying emotional and psychological repercussions, including increased risks of anger, depression, substance abuse, self-harm and obesity.

However, the team noted that there was a noticeable void in acknowledging childhood verbal abuse by adults as a distinct maltreatment subtype and that doing so would be a starting point for its identification and prevention.

Co-author, Professor Peter Fonagy (UCL Psychology & Language Sciences), said: “This systematic review is timely and of significant clinical value. Preventing the maltreatment of children is the most effective way we can reduce the prevalence of child mental health problems. A sharp focus on childhood verbal abuse by adults around them by the new charity Words Matter, and this review will help make significant change, and support and direct our efforts to identify and respond to this risk in an effective and timely manner.” 

Data from the World Health Organization (WHO) has found that emotional abuse is now the most prevalent form of child maltreatment, ahead of physical or sexual abuse.*

However, researchers found that the term “emotional abuse” was ambiguous and focused on the victim.

Whereas the term “childhood verbal abuse” zeroes in on the adult’s actions and this onus could be a starting point for prevention, were it to be made a subtype in its own right.

There was also a range of varying terminology associated with “verbal abuse” across the studies, with terms such as “verbal aggression”, “verbal hostility” and “verbal abuse” being used - highlighting the need for standardised terminology in this area.

The review found that the main perpetrators of childhood verbal abuse by adults were parents (76.5%), other adult caregivers in the home (2.4%), and teachers (12.71%). Other adults noted were coaches (0.6%) and police (0.6%).

Shouting and screaming were the most documented characteristics of verbal abuse. However, the research emphasises that definitions of childhood verbal abuse should not only consider the words used but also the intent, delivery, and the immediate impact on children.

More research would need to be carried out on specific age groups to further understand the effects of this behaviour.

Lead author, Professor Shanta Dube (Wingate University, US), said: “Childhood verbal abuse desperately needs to be acknowledged as an abuse subtype, because of the lifelong negative consequences.

“We’ve seen tremendous strides in increased awareness and interventions targeting physical and sexual abuse perpetrators leading to the reduction in these forms of maltreatment. If we focus on ‘verbal abuse’ by perpetrators rather than just ‘emotional abuse’ among victims, we may develop similar actions to prevent childhood verbal abuse and its consequences.

“Breaking the intergenerational cycles starts with the adults.”

Jessica Bondy, Founder of Words Matter, a newly established charity with the mission of enhancing children’s overall health and wellbeing by curtailing verbal abuse by adults in their lives, said: “It’s paramount to grasp the true scale and impact of childhood verbal abuse. All adults get overloaded sometimes and say things unintentionally. We have to work collectively to devise ways to recognise these actions and end childhood verbal abuse by adults so children can flourish.

“Words have weight, they can uplift or destroy. Let’s build children up, not knock them down.”
